[0033] Referring to FIG. 2, there is depicted is a flowchart illustrating a method for automatically controlling a breezeless mode of an air conditioner according to a first embodiment of the present disclosure.
[0034] In one embodiment, the method for automatically controlling the breezeless mode of the air conditioner includes:
Operation S10, obtaining a maximum triggering distance after the air conditioner is in a cooling mode;
In this embodiment, the pulse width modulation (PWM) signal of the preset infrared module in the air conditioner is detected, and the corresponding duty ratio is obtained, after it is detected the air conditioner is in the cooling mode. The duty cycle is the ratio of the energization time to a total time in one pulse cycle. The higher the infrared emission power exists, the higher the corresponding duty ratio exists, thereby the infrared mode can detect a farther distance. Therefore, the corresponding duty ratio can be obtained by adjusting the infrared emission power of the infrared module, and the maximum triggering distance D can be calculated according to the duty ratio x, where the D=-a∗x^2+b∗x+c, where the a, b, c are constant values, and taking a=0.001, b=0.07, c=0.997. For a fixed air conditioner, the infrared emission power of the infrared module is adjusted according to the actual needs, so that a fixed duty ratio x can be obtained. Therefore, the pulse width modulation (PWM) signal of the preset infrared module in the air conditioner is detected, and the corresponding duty ratio is obtained, after it is detected the air conditioner is in the cooling mode. So that the maximum triggering distance L0 can be calculated and obtained according to the above formula.
[0035] Operation S20: detecting whether there is a target obstacle in an air supply direction of the air conditioner, and detecting whether a distance between the target obstacle and the air conditioner is less than or equal to the maximum trigger distance; and
In this embodiment, the target obstacle can be a child or an adult. That is, whether there is a child or an adult exists is detected, and whether the distance L between the children or the adult from the air conditioner is less than or equal to the maximum triggering distance L0. In this embodiment, the air conditioner can be the cabinet air conditioner, and the cabinet air conditioner is configured with an infrared module group, which includes an upper infrared module group and a lower infrared module group. The distance between the upper infrared module and the bottom of the cabinet air conditioner is greater than an average height of children. A distance between the lower infrared module and the bottom of the cabinet air conditioner is less than the average height of children. And an average height of children is set according to the actual situation, for example, 1.2 meters. Referring to FIG. 3, there is depicted a scene diagram illustrating an air supply of the air conditioner of a method for automatically controlling a breezeless mode of an air conditioner according to an embodiment of the present disclosure.
[0036] In this embodiment, both the upper infrared module and the lower infrared module can receive the infrared rays in the detection range, and the detection directions of the upper infrared module and the lower infrared module are consistent or substantially the same as the air supply direction of the air conditioner. For example, the detection directions of the upper infrared module and the lower infrared module are parallel to the horizontal plane, and perpendicular to the front side of the air conditioner (the front side where the air outlet of the air conditioner located). Because of the infrared wavelength of the human body's radiation is mainly concentrated at about 10000 nm, and according to the characteristics of the infrared of the human body's radiation, an range such as from 9500 nm to 10500 nm can be set (which to be set specifically according to the actual conditions). When the infrared wavelength that detected by the lower infrared module is in the range from 9500 nm to 10500nm, and the infrared wavelength that detected by the upper infrared module is not in the range from 9500nm to 10500nm, which means that the lower infrared module detects the human body, and the upper infrared module does not detect the human body. That is, it determines that a first type of target obstacle exists, and the first type of target obstacle is the child. When the infrared wavelength that detected by the upper infrared module is in the range from 9500 nm to 10500 nm, this indicates that the upper infrared module detects the human body, that is, it is determined that a second type of target obstacle exist, and the second type of target obstacle is one adult.
[0037] After determining that the target obstacle exist, the distance between the target obstacle and the air conditioner is further determined. In this embodiment, for example, the upper infrared modules and the lower infrared modules include an infrared ranging sensor. And the infrared ranging sensor includes: a pair of diodes with one infrared signal transmitting diode and one infrared signal receiving diode. And an infrared light to be emitted by using the infrared ranging sensor, and to form a reflection process after that illuminates the object. And the signal is received after being reflected to the sensor, and then the Charged Coupled Device (CCD) is configured to receive the data of the lag difference between the transmission and the reception. The distance of the object is calculated after the data of the lag difference being processed by the signal processor. That is, after determined there is the target obstacle, the infrared signal of the specific frequency is transmitted through the infrared signal transmitting diode of the infrared ranging sensor in the infrared module, and the infrared signal receiving diode receives the specific frequency infrared signal. And when the infrared detecting direction exists the target obstacle, the infrared signal is reflected back and received by the infrared signal receiving diode. After being processed, the infrared return signal can be configured to calculate the distance L that between the target obstacle and the air conditioner (when it is determined that there is the first type of target obstacle, the distance L between the first type of target obstacle and the air conditioner is detected by the lower infrared module. The distance between the second type target obstacle and the air conditioner is detected by the upper infrared module, when there is the second type of target obstacle).
[0038] After calculating and obtaining the distance L between the target obstacle and the air conditioner, detecting whether the distance L is less than or equal to the maximum triggering distance L0. The target obstacle is nearer to the air conditioner, in response to a determination that the distance L is less than or equal to the distance L0.
[0039] Operation S30, turning on the breezeless mode corresponding to the target obstacle in response to a determination that the distance is less than or equal to the maximum trigger distance, obtaining an operating parameter of the air conditioner, and controlling the air conditioner to operate according to the operating parameter.
[0040] In this embodiment, in response to a determination that the distance L between the target obstacle and the air conditioner is less than or equal to the maximum triggering distance, the human body is nearer to the air conditioner, and the air conditioner is in a cooling mode, which may cause the human body to catch a cold. So it needs to turn on the breezeless mode, according to the type of the target obstacle, in response to a determination that the distance L between the target obstacle and the air conditioner is less than or equal to the maximum triggering distance. And in response to a determination that the target obstacle is a first target obstacle, that the first type of target obstacle is the child, the lower breezeless mode of the air conditioner should be turned on, the operating parameter is received, and the air conditioner is controlled to operate according to the operate parameter. And in response to a determination that the target obstacle is a second target obstacle, that the second type of target obstacle is an adult, the total breezeless mode of the air conditioner is turned on, the operating parameters is received, and the air conditioner to the operate parameters is controlled.
[0041] In one embodiment of the present disclosure, in response to a determination that the target obstacle is the first type of target obstacle of the children, the lower breezeless mode of the air conditioner is turned on. And the local air temperature, the draft rate, the local airflow rate, the fan speed and the turbulence intensity in the air conditioner operating environment are firstly obtained. The theoretical target temperature is calculated according to the draft rate. And the target temperature is obtained according to the theoretical target temperature and the set temperature. And finally the operating parameters are obtained according to the target temperature and the local air temperature.
[0042] In one embodiment of the present disclosure, the local air temperature is determined by the outlet air temperature. According to the type of the breezeless mode, the outlet air temperature of tc is collected: tc1 is collected when the upper breezeless mode is turned on, tc2 is collected when the lower breezeless mode is turned on, and tc2 is collected when the the total breezeless mode is turned on. According to the correlation formula, the local air temperature value ta of an area with an altitude of 2.5 meters is calculated: the upper breezeless mode is turned on with the local air temperature value ta 1, the lower breezeless mode is turned on with the local air temperature value ta 2, and the total breezeless mode is turned on with the local air temperature value ta 3. The correlation formula between the outlet air temperature and the local air temperature is: ta=atc+b, and ta is the local air temperature, tc is the outlet air temperature, a and b are both constants, a corresponding to different types of breezeless mode are different, and b corresponding to different types of breezeless mode are different. For example, in response to a determination that the type of the breezeless mode is the lower breezeless, the correlation formula between the outlet air temperature and the local air temperature is: ta=0.2307tc+23.955. When the type of the breezeless mode is the lower breezeless, the temperature collected by the preset temperature sensor at the air outlet, namely the outlet air temperature, is tc. tc can be substituted into the above formula to obtain the local air temperature.
[0043] In this embodiment, the draft rate is determined by the type of the breezeless mode. It should be preset that: the draft rate DR1 of the upper breezeless mode is 5, the draft rate of the lower breezeless mode of DR2=10, and the draft rate of the total breezeless of DR3=5. For example, in response to a determination that it is determined that the type of the breezeless mode is the lower breezeless, the draft rate DR is 10.
[0044] In one embodiment of the present disclosure, the local airflow rate is related to the air duct structure, the fan speed, or the like. The local airflow rate Va only relates to the fan (such as a fan of the air conditioner, the fan in the following can also be a fan of air conditioner) speed F (F has a range from 1% to 100%). The relationship formula between the local airflow rate Va and the fan speed F is: Va=cF+d, c and d both are constants, and the value of c corresponding to different breezeless mode, the value of d corresponding to different breezeless mode. That is, the upper breezeless mode corresponds to c1 and d1, the lower breezeless mode corresponds to c2 and d2, and the total breezeless mode corresponds to c3 and d3. For example, in response to a determination that the type of the breezeless mode is the lower breezeless mode, the relationship formula between the local airflow rate Va and the fan speed F is: Va=0.0352F+0.1366. In response to a determination that it is determined that the type of the breezeless mode is the lower breezeless, the fan speed F can be obtained, according to substitute the local airflow rate into the above formula, for example, the local airflow rate is an initial value of 0.3 m/s.
[0045] In one embodiment of the present disclosure, the turbulence intensity is related to the air duct structure, the fan speed and the stability. And the turbulence intensity only related to the fan speed. The relationship formula between the turbulence intensity Tu and the fan speed F is: Tu=eF2+fF+g, e, f, and g are constants, and the value of e corresponding to different breezeless mode, the value of f corresponding to different breezeless mode, the value of g corresponding to different breezeless mode. That is the upper breezeless mode corresponds to e1=0, f1=0, and g1=36.4, and the lower breezeless mode corresponds to e2=-12.858, f2=29.244, and g2=21.424, and the total breezeless mode corresponds to e3=0, f3=0, and g3=29.6. For example, when the type of the breezeless mode is the lower breezeless mode, the relationship formula between the turbulence intensity Tu and the fan speed F is: Tu=-12.858F2+29.244F+21.424. When the type of the breezeless mode is the lower breezeless, the fan speed F is obtained, and the turbulence intensity Tu is obtained by the speed F substituted into the above formula.
[0046] In this embodiment, the set temperature is a temperature value preset by the user. For example, after the air conditioner is turned on, the user set a temperature, such as 25 °C, namely the set temperature.
[0047] In 1988, Fanger proposed a model for predicting the dissatisfaction of breezeless. Based on this model,the draft rate DR in IS07730-2005 is used to characterized the human dissatisfaction caused by the wind draft feeling. The formula of the draft rate is:
[0048] DR=(34-tas)(Va-0.05)0.62(0.37×Va×Tu+3.14), where DR is the draft rate, in response to a determination that DR is larger than 100%, and DR is equal to 100%; tas is the theoretical target temperature, and the sign for temperature is °C; Va is the local airflow rate, m/s; Tu is the turbulence intensity.
[0049] tas of the theoretical target temperature is obtained, through substituting the draft rate DR, the local airflow rate Va, and the turbulence intensity into the above formula.
[0050] In one embodiment of the present disclosure, when the target obstacle is a child, the target temperature can be obtained according to the theoretical target temperature and the set temperature.
[0051] When the set temperature is less than 24 °C, and the theoretical target temperature of tas is less than 24 °C, the target temperature is set as 24 °C. The target temperature is set as 29 °C, when the theoretical target temperature of tas is greater than 29 °C. When the theoretical target temperature is at the range from 24 °C to 29 °C, the theoretical target temperature is set as the target temperature.
[0052] When the set temperature is greater than or equal to 24 °C, and less than or equal to 28 °C, and the theoretical target temperature of tas is less than 24 °C, thus the target temperature is set as 24 °C. When the theoretical target temperature of tas is greater than 29 °C, thus the target temperature is set as 28 °C. When the theoretical target temperature is between 24 °C and 29 °C, then the theoretical target temperature is the target temperature.
[0053] When the set temperature is greater than 28 °C, and the theoretical target temperature of tas is less than 24 °C, thus the target temperature is set as 24 °C. When the theoretical target temperature of tas is greater than 29 °C, thus the target temperature is set as 29 °C. when the theoretical target temperature is between 24 °C and 29 °C, then the theoretical target temperature is the target temperature.
[0054] After obtaining the target temperature, the target temperature of tas is compared with the local air temperature of the ta. First, whether the difference between tas and ta is greater than a preset value is detected. For example, whether the difference between tas and ta is greater than 1 is detected. And when the difference between tas and ta is not exceed 1, thus the parameter of the air conditioner is maintained. When the difference between tas and ta is greater than 1. There are two cases, one case is that tas is greater than ta, and the difference is greater than 1; and another one is that tas is less than ta, and the difference is greater than 1. That is, the difference between ta and tas have two ranges, in the which the first range is (1, ∞), that is, tas is less than ta, and the difference is greater than 1. And in the which the second range is (-∞, -1), that is, tas is greater than ta, And the difference is greater than 1. When the difference between tas and ta is in the first range, thus the compressor frequency is increased by a preset value. For example, the compressor frequency is increased by 1 hz, and the running time is 3 min. In response to a determination that the difference between tas and ta is in the second range, thus the compressor frequency is lowered by a preset value, such as 1 hz, and the running time is 3 min. In another embodiment of the present disclosure, when the compressor frequency is lowered to a minimum value. For example, the minimum value is set as 20 hz, the initial value of the local airflow rate of 0.3 m/s is lowered by a preset value, for example, by which the preset value of 0.1. That is, when the compressor frequency is lowered to 20 hz, thus the local airflow rate is lowered to 0.2 m/s, and the calculated fan speed F is 1.8011, according to the lower breezeless. And the relationship formula between the local airflow rate Va and the fan speed F: Va=0.0352F+0.1366. And running with the compressor frequency of 20hz and the fan speed of 1.8011, and the running time is 3 min at this moment (the running time that can be maintained according to the actual needs, and the running time is not be limited here).
[0055] In another embodiment of the present disclosure, in response to a determination that the target obstacle is an adult, thus turning on the breezeless mode of the air conditioner, and the subsequent process is similar to the process of that in response to a determination that the target obstacle is a child. That is, firstly the local air temperature, the draft rate, the local airflow rate, the fan speed, and the turbulence intensity in the air conditioner operating environment are obtained by the air conditioner in the total breezeless mode. And then the theoretical target temperature be calculated and obtained according to the draft rate, the local airflow rate, and the turbulence intensity. In the step of obtaining the target temperature based on the theoretical target temperature and the set temperature, the range of the target temperature is from 24 °C to 27 °C. After the target temperature being obtained, the target temperature of tas is compared with the local air temperature of the ta. First, it is detecting whether the difference between tas and ta is greater than a preset value. For example, whether the difference between tas and ta is greater than 0.5. And in response to a determination that the difference between tas and ta is not exceed 0.5, the parameter of the air conditioner is maintained. in response to a determination that the difference between tas and ta is greater than 0.5, it exist two cases: one is that tas is greater than ta, and the difference is greater than 0.5; and one is that tas is less than ta, and the difference is greater than 0.5. That is, the difference between ta and tas has two ranges, the first range is (0.5, ∞), that is, tas is less than ta, and the difference is greater than 0.5. And the second range is (-∞, -0.5), that is, tas is greater than ta, and the difference is greater than 0.5. In response to a determination that the difference between tas and ta is in the first range, thus the compressor frequency is increased by a preset value, for example, the compressor frequency is increased by 1 hz, and the running time is 3 min. In response to a determination that the difference between tas and ta is in the second range, thus the compressor frequency is then lowered by a preset value, such as reducing the compressor frequency by 1 hz and the running time is 3 min. In another embodiment of the present disclosure, in response to a determination that the compressor frequency is lowered to a minimum value, for example, the minimum value is 20 hz. The initial value of the local airflow rate of 0.3 m/s is lowered by a preset value, for example, by which the preset value of 0.1. That is, in response to a determination that the compressor frequency is lowered to 20 hz, and the local airflow rate is lowered to 0.2 m/s, the fan speed is calculated according to the relationship formula between the local airflow rate Va and the fan speed F according to the total breezeless. And running with the compressor frequency of 20hz and the fan speed, and the running time is 3 min at this moment (the running time that can be maintained according to the actual needs, and the running time is not be limited here).
[0056] According to the present disclosure, obtaining a maximum triggering distance after the air conditioner is in a cooling mode, turning on the breezeless mode corresponding to the target obstacle in response to a determination that the distance is less than or equal to the maximum trigger distance, obtaining an operating parameter of the air conditioner, and controlling the air conditioner to operate according to the operating parameter. According to the present disclosure, the air conditioner can be triggered to turn on the breezeless mode according to the type of the human body, in response to a determination that the air conditioner is in the cooling mode, and the human body is nearer to the air conditioner, and the distance between the human body and the air conditioner is less than or equal to the maximum triggering distance. Thereby realizing the adjustment of the operating parameter of air conditioning, so that to the wind blown by the air conditioner is comfortable for the human body, and avoiding people catch a cold due to they are too close to the air conditioner, and guaranteed the user's health during the use of the air conditioner.
[0057] Further, in one embodiment of the method for automatically controlling a breezeless mode of an air conditioner of the present disclosure, S10 includes:
obtaining a duty ratio in response to a detection that the air conditioner is in the cooling mode; and
calculating the maximum triggering distance according to the duty ratio.
[0058] In this embodiment, the pulse width modulation (PWM) signal of the preset infrared module in the air conditioner is detected, and the corresponding duty ratio is obtained, after it is detected the air conditioner is in the cooling mode. The duty cycle is the ratio of the energization time to a total time in one pulse cycle. The higher the infrared emission power exists, the higher the corresponding duty ratio exists, thereby the infrared mode can detect a farther distance. Therefore, the corresponding duty ratio can be obtained by adjusting the infrared emission power of the infrared module, and the maximum triggering distance D can be calculated according to the duty ratio x, where the D=-a∗x^2+b∗x+c, where the a, b, c are constant values, and taking a=0.001, b=0.07, c=0.997. For a fixed air conditioner, the infrared emission power of the infrared module is adjusted according to the actual needs, so that a fixed duty ratio x can be obtained. Therefore, the pulse width modulation (PWM) signal of the preset infrared module in the air conditioner is detected, and the corresponding duty ratio is obtained, after it is detected the air conditioner is in the cooling mode. So that the maximum triggering distance L0 can be calculated and obtained according to the above formula.
[0059] In this embodiment, the maximum triggering distance is calculated. And when the distance between the target obstacle child or the adult and the air conditioner is less than or equal to the maximum triggering distance, it indicates that the target obstacle is nearer to the air conditioner. The breezeless mode of the air conditioner corresponding to the target obstacle should be turned on to free children on to free children or adults from cold wind.
[0060] Further, in one embodiment of the method for automatically controlling a breezeless mode of an air conditioner of the present disclosure, the method is applied to a cabinet air conditioner, and the cabinet air conditioner includes an upper infrared module and a lower infrared module, a distance between the upper infrared module and a bottom of the cabinet air conditioner is greater than an average height of children, and a distance between the lower infrared module and the bottom of the cabinet air conditioner is less than the average height of children, and the operation of detecting whether there is a target obstacle in an air supply direction of the air conditioner includes:
judging whether the upper infrared module detects an infrared signal of a human body, and whether the lower infrared module detects the infrared signal of the human body;
determining there is a first type of the target obstacle, in response to a determination that the upper infrared module does not detect the infrared signal of the human body and the lower infrared module detects the infrared signal of the human body; and
determining there is a second type of the target obstacle, in response to a determination that the upper infrared module detects the infrared signal of the human body.
[0061] In this embodiment, the target obstacle refers to a child or an adult. That is, detecting whether there is a child or an adult is exist, and whether the distance L between the children or the adult from the air conditioner is less than or equal to the maximum triggering distance L0. In this embodiment, the air conditioner refers to the cabinet type air conditioner, and there is a first type of target obstacle, which including an upper infrared module group and a lower infrared module group. Where the distance between the upper infrared module and the bottom of the cabinet air conditioner is greater than an average height of children. The distance between the lower infrared module and the bottom of the cabinet air conditioner is less than the average height of children. And an average height of children is set according to the actual situation, for example, 1.2 meters. Referring to FIG. 3, there is depicted a scene diagram illustrating an air supply of the air conditioner of a method for automatically controlling a breezeless mode of an air conditioner according to an embodiment of the present disclosure.
[0062] In this embodiment, both the upper infrared module and the lower infrared module can receive the infrared rays in the detection range, and the detection directions of the upper infrared module and the lower infrared module are consistent or substantially the same as the air supply direction of the air conditioner. For example, the detection directions of the upper infrared module and the lower infrared module parallel to the horizontal plane, and perpendicular to the front side of the air conditioner (the front side where the air outlet of the air conditioner located). Because of the infrared wavelength of the human body's radiation is mainly concentrated at about 10000 nm, and according to the characteristics of the infrared of the human body's radiation, an range such as from 9500 nm to 10500 nm can be set (which to be set specifically according to the actual conditions). And when the infrared wavelength that detected by the lower infrared module is in the range from 9500 nm to 10500nm, and the infrared wavelength that detected by the upper infrared module is not in the range from 9500 nm to 10500nm, which means that the lower infrared module detects the human body, and the upper infrared module does not detect the human body. That is, it determines that a first type of target obstacle exist, and the first type of target obstacle is the children. When the infrared wavelength that detected by the upper infrared module is in the range of 9500 nm to 10500 nm, this indicates that the upper infrared module detects the human body, that is, it is determined that there is a second type of target obstacle currently, and the second type of target obstacle is an adult.
[0063] Further, in one embodiment of the method for automatically controlling a breezeless mode of an air conditioner of the present disclosure, the operation of "detecting whether a distance between the target obstacle and the air conditioner is less than or equal to the maximum trigger distance" includes:
detecting the distance between the first or second type target obstacle and the air conditioner through the infrared module; and
judging whether the distance between the first or second type target obstacle and the air conditioner is less than or equal to the maximum trigger distance.
[0064] After determining that there is a target obstacle, the distance between the target obstacle and the air conditioner is further determined. In this embodiment, for example, the infrared modules include an infrared ranging sensor, and the infrared ranging sensor includes: a pair of diodes with one infrared signal transmitting diode and one infrared signal receiving diode. And an infrared light to be emitted by using the infrared ranging sensor, and to form a reflection process after that illuminates the object, the signal is received after being reflected to the sensor, and then the Charged Coupled Device (CCD) is configured to receive the data of the lag difference between the transmission and the reception. The distance of the object is calculated after the data of the lag difference being processed by the signal processor. That is, after it is determined that there is the target obstacle, the transmitting of the infrared ranging sensor in the lower infrared module emits a specific frequency infrared signal, and the infrared signal receiving diode receives the specific frequency infrared signal. And when the infrared detecting direction exists the target obstacle, the infrared signal is reflected back and received by the infrared signal receiving diode. After being processed, the infrared return signal can be configured to calculate the distance L that between the target obstacle and the air conditioner.
[0065] After calculating and obtaining the distance L between the target obstacle and the air conditioner, detecting whether the distance L is less than or equal to the maximum triggering distance L0. The target obstacle is nearer to the air conditioner, when the distance L is less than or equal to the distance L0. The corresponding breezeless mode of the air conditioner can be triggered to be turned on, thereby realizing the adjustment of the operating parameter of air conditioning, so that to the wind blown by the air conditioner is comfortable for the human body, and avoiding people catch a cold due to they are too close to the air conditioner, and guaranteed the user's health during the use of the air conditioner.
[0066] Further, in one embodiment of the method for automatically controlling a breezeless mode of an air conditioner of the present disclosure, the operation of "turning on the breezeless mode corresponding to the target obstacle, obtaining an operating parameter of the air conditioner, and controlling the air conditioner to operate according to the operating parameter " includes:
turning on the breezeless mode according to type of the target obstacle, obtaining an environmental parameter, and obtaining a target temperature according to a draft rate, a local airflow rate, and a turbulence intensity in the environmental parameter; and
obtaining a local air temperature in the environmental parameter, calculating a difference between the local air temperature and the target temperature, obtaining the operating parameter of the air conditioner according to a range where the difference is located, and controlling the air conditioner to operate according to the operating parameter.
[0067] In this embodiment, when the distance L between the target obstacle and the air conditioner is less than or equal to the maximum triggering distance, the human body is nearer to the air conditioner, and the air conditioner is in a cooling mode, at this time user may catch a cold. The breezeless mode can be turned on according to the type of the target obstacle, when the distance L between the target obstacle and the air conditioner is less than or equal to the maximum triggering distance. And when the target obstacle is a first target obstacle, and the first type of target obstacle is the children, the lower breezeless mode of the air conditioner is turned on, the operating parameter is received, and the air conditioner is controlled to operate according to the operate parameter. And when the target obstacle is the second target obstacle, and the second type of target obstacle is an adult, the total breezeless mode of the air conditioner is turned on, the operating parameter is received, and the air conditioner is controlled to operate according to the operate parameter.
[0068] In one embodiment of the present disclosure, when the target obstacle is the first type of target obstacle, such as one child, the lower breezeless mode of the air conditioner is turned on. And the local air temperature, the draft rate, the local airflow rate, the fan speed and the turbulence intensity in the air conditioner operating environment are obtained first. The theoretical target temperature is obtained according to calculating the draft rate, the local airflow rate, and the turbulence intensity. The target temperature is obtained according to the theoretical target temperature and the set temperature. Finally the operating parameter is obtained according to the target temperature and the local air temperature.
[0069] In one embodiment of the present disclosure, the local air temperature is determined by the outlet air temperature. The outlet air temperature of tc is collected according to the turn on breezeless mode: tc1 is collected when the upper breezeless mode is turned on, tc2 is collected when the lower breezeless mode is turned on, and tc2 is collected when the the total breezeless mode is turned on. According to the correlation formula, the local air temperature value of ta that at 2.5 meters is calculated: the upper breezeless mode is turned on with the local air temperature value ta 1, the lower breezeless mode is turned on with the local air temperature value ta 2, and the total breezeless mode is turned on with the local air temperature value ta 3. In where the correlation formula between the outlet air temperature and the local air temperature is: ta=atc+b, where ta is the local air temperature, tc is the outlet air temperature, and the a and b are both constants, and a corresponding to different types of breezeless mode are different, and b corresponding to different types of breezeless mode are different. For example, when the type of the breezeless mode is the lower breezeless, the correlation formula between the outlet air temperature and the local air temperature is: ta=0.2307tc+23.955. When in the lower breezeless mode, the outlet air temperature collected by the set temperature sensor is defined as outlet air temperature tc, which is substituted into the above formula to obtain the local air temperature.
[0070] In this embodiment, the draft rate is determined by the breezeless mode, of which should be preset: the draft rate of the upper breezeless mode DR1 is 5, the draft rate of the lower breezeless mode of DR2 is 10, and the draft rate of the total breezeless of DR3 is 5. For example, when in the lower breezeless, the draft rate DR which is 10 is acquired.
[0071] In one embodiment of the present disclosure, the local airflow rate is related to the air duct structure, the fan speed, or the like. The local airflow rate Va only relates to the fan (such as a fan of the air conditioner, the fan in the following can also be a fan of air conditioner) speed F (F has a range from 1% to 100%). The relationship formula between the local airflow rate Va and the fan speed F is: Va=cF+d, in where c and d both are constants, and the value of c corresponding to different total breezeless mode, the value of d corresponding to different total breezeless mode. That is, the upper breezeless corresponds to c1 and d1, the lower breezeless corresponds to c2 and d2, and the total breezeless corresponds to c3 and d3. For example, when the type of the breezeless mode is the lower breezeless mode, the relationship formula between the local airflow rate Va and the fan speed F is: Va=0.0352F+0.1366. When in lower breezeless mode, the fan speed F can be obtained, by substituting the local airflow rate into the above formula, for example, the local airflow rate is an initial value of 0.3 m/s.
[0072] In one embodiment of the present disclosure, the turbulence intensity is related to the air duct structure, the fan speed and the stability, and which can be approximated as that the turbulence intensity only related to the fan speed. The relationship formula between the turbulence intensity Tu and the fan speed F is: Tu=eF2+fF+g, where e, f, and g are constants, and the value of e corresponding to different breezeless mode, the value of f corresponding to different breezeless mode, the value of g corresponding to different breezeless mode. That is the upper breezeless corresponds to e1=0, f1=0, and g1=36.4, and the lower breezeless corresponds to e2=-12.858, f2=29.244, and g2=21.424, and the total breezeless corresponds to e3=0, f3=0, and g3=29.6. For example, when the type of the breezeless mode is the lower breezeless, the relationship formula between the turbulence intensity Tu and the fan speed F is: Tu=-12.858F2+29.244F+21.424. When it is determined that the type of the breezeless mode is the lower breezeless , the fan speed F is obtained, and to obtain the turbulence intensity Tu by substituting the speed F into the above formula.
[0073] In this embodiment, the set temperature is a preset by user. For example, after turning on the air conditioner, the user can set a temperature, such as 25 °C, namely the set temperature.
[0074] In 1988, Fanger proposed a model for predicting the dissatisfaction of breezeless. Based on this model,the draft rate DR in IS07730-2005 is used to characterized the human dissatisfaction caused by the wind draft feeling. The formula of the draft rate is:
where DR is the draft rate, when DR is greater than 100%, then DR is equal to 100%; tas is the theoretical target temperature, and the sign for temperature is °C; Va is the local airflow rate, m/s; Tu is the turbulence intensity.
[0075] tas of the theoretical target temperature is obtained by substituting the draft rate DR, the local airflow rate Va, and the turbulence intensity into the above formula.
[0076] In one embodiment of the present disclosure, when the target obstacle is a child, the target temperature can be obtained according to the theoretical target temperature and the set temperature.
[0077] When the set temperature is less than 24 °C, and the theoretical target temperature of tas is less than 24 °C, the target temperature is set as 24 °C. The target temperature is set as 29 °C, when the theoretical target temperature of tas is greater than 29 °C. When the theoretical target temperature is at the range from 24 °C to 29 °C, the theoretical target temperature is set as the target temperature.
[0078] When the set temperature is greater than or equal to 24 °C, and less than or equal to 28 °C, and the theoretical target temperature of tas is less than 24 °C, thus the target temperature is 24 °C. When the theoretical target temperature of tas is greater than 29 °C, thus the target temperature is 28 °C. When the theoretical target temperature is between 24 °C and 29 °C, then the theoretical target temperature is the target temperature.
[0079] When the set temperature is greater than 28 °C, and the theoretical target temperature of tas is less than 24 °C, thus the target temperature is 24 °C. When the theoretical target temperature of tas is greater than 29 °C, thus the target temperature is 29 °C. When the theoretical target temperature is between 24 °C and 29 °C, then the theoretical target temperature is the target temperature.
[0080] After obtaining the target temperature, the target temperature of tas is compared with the local air temperature ta. First, whether the difference between tas and ta is greater than a preset value is detected. For example, whether the difference between tas and ta is greater than 1 is detected. When the difference between tas and ta is not exceed 1, thus the parameter of the air conditioner is maintained. When the difference between tas and ta is greater than 1, there are two cases, one case is that tas is greater than ta, and the difference is greater than 1; and another one is that tas is less than ta, and the difference is greater than 1. That is, the difference between ta and tas have two ranges, the first range is (1, oo), that is, tas is less than ta, and the difference is greater than 1. The second range is (-∞, -1), that is, tas is greater than ta, and the difference is greater than 1. When the difference between tas and ta is in the first range, the compressor frequency is increased by a preset value, for example, the compressor frequency is increased by 1 hz, and the running time is 3 min. When the difference between tas and ta is in the second range, the compressor frequency is lowered by a preset value, such as the compressor frequency is reduced by 1 hz and the running time is 3 min. In another embodiment of the present disclosure, when the compressor frequency is lowered to a minimum value. For example, the minimum value is set as 20 hz, the initial value of the local airflow rate of 0.3 m/s is lowered by a preset value, for example, by which the preset value of 0.1. That is, when the compressor frequency is lowered to 20 hz, thus the local airflow rate is lowered to 0.2 m/s, and the fan speed F=1.8011 is calculated, according to the lower breezeless. And the relationship formula between the local airflow rate Va and the fan speed F: Va=0.0352F+0.1366. And running with the compressor frequency of 20hz and the fan speed of 1.8011, and the running time is 3 min at this moment (the running time that can be set according to the actual needs, and the running time is not be limited here).
[0081] In another embodiment of the present disclosure, when the target obstacle is an adult, the breezeless mode of the air conditioner is turned on, and the subsequent process is similar to the process of that when the target obstacle is a child. That is, firstly the local air temperature, the draft rate, the local airflow rate, the fan speed, and the turbulence intensity in the air conditioner operating environment are obtained by the air conditioner in the total breezeless mode. And then the theoretical target temperature be calculated and obtained according to the draft rate, the local airflow rate, and the turbulence intensity. In the step of obtaining the target temperature based on the theoretical target temperature and the set temperature, the range of the target temperature is from 24 °C to 27 °C. After obtaining the target temperature, the target temperature of tas is compared with the local air temperature of the ta. First, it is detecting whether the difference between tas and ta is greater than a preset value. For example, whether the difference between tas and ta is greater than 0.5. And when the difference between tas and ta is not exceed 0.5, the parameter of the air conditioner is maintained. When the difference between tas and ta is greater than 0.5, it exist two cases: one is that tas is greater than ta, and the difference is greater than 0.5; and one is that tas is less than ta, and the difference is greater than 0.5. That is, the difference between ta and tas has two ranges, the first range is (0.5, ∞), that is, tas is less than ta, and the difference is greater than 0.5. And the second range is (-∞, -0.5), that is, tas is greater than ta, and the difference is greater than 0.5. When the difference between tas and ta is in the first range, thus the compressor frequency is increased by a preset value, for example, the compressor frequency is increased by 1 hz, and the running time is 3 min. When the difference between tas and ta is in the second range, thus the compressor frequency is then lowered by a preset value, such as reducing the compressor frequency by 1 hz and the running time is 3 min. In another embodiment of the present disclosure, when the compressor frequency is lowered to a minimum value, for example, the minimum value is 20 hz. The initial value of the local airflow rate of 0.3 m/s is lowered by a preset value, such as 0.1. That is, when the compressor frequency is lowered to 20 hz, and the local airflow rate is lowered to 0.2 m/s, the fan speed is calculated according to the relationship formula between the local airflow rate Va and the fan speed F according to the total breezeless mode. And running with the compressor frequency of 20hz and the fan speed, and the running time is 3 min at this moment (the running time can be set according to the actual needs, and the running time is not be limited here).

And in the which the second range is (-∞, -1), that is, tas is greater than ta, And the difference is greater than 1. When the difference between tas and ta is in the first range. Thus it indicates that the local air temperature is higher than the target temperature, and the difference between tas and ta is greater than the preset value, and the temperature reduction process is needed currently. And the compressor frequency is increased by a preset value according to a preset strategy. For example, the compressor frequency is increased by 1 hz (which is the first preset value), and the running time is 3 min (which is the first preset duration).
[0085] In this embodiment, when the target obstacle is the second type of target obstacle, and the second type of target obstacle is the children. the difference between ta and tas has two ranges, the first range is (0.5, ∞), that is, tas is less than ta, and the difference is greater than 0.5. And the second range is (-∞, -0.5), that is, tas is greater than ta, and the difference is greater than 0.5. When the difference between tas and ta is in the first range. It indicates that the local air temperature is higher than the target temperature, and the difference between tas and ta is greater than the preset value, and the temperature reduction process is needed currently. And the compressor frequency is increased by a preset value according to a preset strategy. For example, the compressor frequency is increased by 1 hz (which is the first preset value), and the running time is 3 min (which is the first preset duration).
[0086] In this embodiment, when the target temperature is lower than the local air temperature, and the difference between tas and ta is greater than the preset value, it indicates that the local air temperature is high, and the temperature reduction process is needed. And the operating parameter of air conditioning is adjusted according to the preset adjustment strategy, and the air conditioner achieves the adaptive control mode.
[0087] Further, in one embodiment of the method for automatically controlling a breezeless mode of an air conditioner of the present disclosure, the operation of "obtaining the operating parameter of the air conditioner according to a range where the difference is located, and controlling the air conditioner to operate according to the operating parameter", includes:

[0088] In this embodiment, when the target obstacle is the first type of target obstacle, and the first type of target obstacle is the children. the difference between ta and tas have two ranges, in the which the first range is (1, ∞), that is, tas is less than ta, and the difference is greater than 1. And in the which the second range is (-∞, -1), that is, tas is greater than ta, And the difference is greater than 1. In response to a determination that the difference between tas and ta is in the second range. Thus it indicates that the local air temperature is higher than the target temperature, and the difference between tas and ta is greater than the preset value, and the temperature reduction process is needed currently. And the compressor frequency is increased by a preset value according to a preset strategy. For example, the compressor frequency is increased by 1 hz (which is the first preset value), and the running time is 3 min (which is the second preset duration and be freely set according to the actual situation).
[0089] In this embodiment, when the target obstacle is childrenwhich is regarded as the second type of target obstacle. The difference between ta and tas has two ranges, the first range is (0.5, ∞), that is, tas is less than ta, and the difference is greater than 0.5. And the second range is (-∞, -0.5), that is, tas is greater than ta, and the difference is greater than 0.5.

[0109] Referring to FIG. 4, there is depicted a flowchart illustrating another embodiment of a method for automatically controlling a breezeless mode of an air conditioner according to the present disclosure.
[0110] In one embodiment, the method for automatically controlling a breezeless mode of an air conditioner includes:
In S40, detecting whether there is a target obstacle in an air supply direction of the air conditioner, in response to a determination that the air conditioner is in the cooling mode turn on;
In this embodiment, the air conditioner can be the cabinet air conditioner, and the cabinet air conditioner is configured with an infrared module group, which includes an upper infrared module group and a lower infrared module group. The distance between the upper infrared module and the bottom of the cabinet air conditioner is greater than an average height of children. A distance between the lower infrared module and the bottom of the cabinet air conditioner is less than the average height of children. And an average height of children is set according to the actual situation, for example, 1.2 meters. Referring to FIG. 3, there is depicted a scene diagram illustrating an air supply of the air conditioner of a method for automatically controlling a breezeless mode of an air conditioner according to an embodiment of the present disclosure.
[0111] In this embodiment, both the upper infrared module and the lower infrared module can receive the infrared rays in the detection range, and the detection directions of the upper infrared module and the lower infrared module are consistent or substantially the same as the air supply direction of the air conditioner. For example, the detection directions of the upper infrared module and the lower infrared module are parallel to the horizontal plane, and perpendicular to the front side of the air conditioner (the front side where the air outlet of the air conditioner located). Because of the infrared wavelength of the human body's radiation is mainly concentrated at about 10000 nm, and according to the characteristics of the infrared of the human body's radiation, an range such as from 9500 nm to 10500 nm can be set (which to be set specifically according to the actual conditions). When the infrared wavelength that detected by the lower infrared module is in the range from 9500 nm to 10500nm, and the infrared wavelength that detected by the upper infrared module is not in the range from 9500nm to 10500nm, which means that the lower infrared module detects the human body, and the upper infrared module does not detect the human body. That is, it determines that a second type of target obstacle exists, and the second type of target obstacle is the child. When the infrared wavelength that detected by the upper infrared module is in the range from 9500 nm to 10500 nm, this indicates that the upper infrared module detects the human body, that is, it is determined that a first type of target obstacle exist, and the first type of target obstacle is one adult.
[0112] In S50, detecting whether a distance between the first type of the target obstacle and the air conditioner is less than or equal to a preset threshold, in response to a determination that there is a first type of the target obstacle;
After determining that a target obstacle exist, the distance between the target obstacle and the air conditioner is further determined. In this embodiment, for example, the upper infrared modules and the lower infrared modules include an infrared ranging sensor. And the infrared ranging sensor includes: a pair of diodes with one infrared signal transmitting diode and one infrared signal receiving diode. And an infrared light is emitted by using the infrared ranging sensor, and to form a reflection process after that illuminates the object. And the signal is received after being reflected to the sensor, and then the Charged Coupled Device(CCD) is configured to receive the data of the lag difference between the transmission and the reception. The distance of the object is calculated after the data of the lag difference being processed by the signal processor. That is, after determined that there is the target obstacle, The infrared signal of the specific frequency is transmitted through the infrared signal transmitting diode of the infrared ranging sensor in the infrared module, and the infrared signal receiving diode receives the specific frequency infrared signal. When the infrared detecting direction exists the target obstacle, the infrared signal is reflected back and received by the infrared signal receiving diode. After being processed, the infrared return signal can be configured to calculate the distance L that between the target obstacle and the air conditioner (when it is determined that there is the second type of target obstacle, the distance L between the second type target obstacle and the air conditioner is detected by the lower infrared module. The distance between the first type of target obstacle and the air conditioner is detected by the upper infrared module, when there is the first type of target obstacle).
[0113] In this embodiment, the preset threshold is preset by the user. For example, which is set to 05 m (the preset threshold can be freely set according to the actual situation). When the distance between the target obstacle and the air conditioner is less than the preset threshold, thus the user is nearer to the air conditioner and the air outlet capacity of the air conditioner needs to be controlled.
[0114] In another optional embodiment of the present disclosure, the pulse width modulation (PWM) signal of the preset infrared module in the air conditioner is detected, and the corresponding duty ratio is obtained, after it is detected the air conditioner is in the cooling mode. The duty cycle is the ratio of the energization time to a total time in one pulse cycle. The higher the infrared emission power exists, the higher the corresponding duty ratio exists, thereby the infrared mode can detect a farther distance. Therefore, the corresponding duty ratio can be obtained by adjusting the infrared emission power of the infrared module, and the maximum triggering distance D can be calculated according to the duty ratio x, where the D=-a∗x^2+b∗x+c, where the a, b, c are constant values, and taking a=0.001, b=0.07, c=0.997. For a fixed air conditioner, the infrared emission power of the infrared module is adjusted according to the actual needs, so that a fixed duty ratio x can be obtained. Therefore, the pulse width modulation (PWM) signal of the preset infrared module in the air conditioner is detected, and the corresponding duty ratio is obtained, after it is detected the air conditioner is in the cooling mode. So that the maximum triggering distance L0 can be calculated and obtained according to the above formula.
[0115] In S60, a set temperature of the air conditioner, an environmental temperature changing trend in an air conditioner operating environment, and an outlet air temperature of the air conditioner, in response to a determination that the distance between the first type of target obstacle and the air conditioner is less than or equal to the preset threshold; and
In S70, obtaining a first operating parameter of the air conditioner, and controlling the air conditioner to operate according to the first operating parameters, according to the set temperature, the environmental temperature changing trend, and the outlet air temperature of the air conditioner.
[0116] In this embodiment, the target obstacle includes: the first target type obstacle and the second target type obstacle, which the first target type obstacle is the adult and the second target type obstacle is the children, where the children and the adult respectively correspond to the different control strategies.
[0117] In an optional embodiment of the present disclosure, when the target obstacle is the first type of target obstacle, and the distance L between the first type obstacle and the air conditioner is less than or equal to the threshold value L0, thus the set temperature of the air conditioner, the environmental temperature changing trend and the air conditioner outlet air temperature in the operating environment are obtained. And the operating state of the air guiding strip of the air conditioner, the compressor frequency and the fan speed are adjusted, according to the set temperature of the air conditioner, the environmental temperature changing trend and the air conditioner outlet air temperature in the operating environment. In where, the set temperature of the air conditioner refers to a target indoor adjustment temperature of the air conditioner by the user through the remote controller or other means. The set temperature of the air conditioner reflects the user's wishes, and also represents the adjustment target of the air conditioner. A temperature sensor is configured on the air conditioner indoor unit, and the indoor temperature is collected every preset time in response to a determination that the air conditioner is in the cooling mode. For example, in a cycle of 10 minutes, when the measured temperature value is t1, then the temperature value that measured 10 minutes ago is t0. And in response to a determination that t1 is greater than t0, the environmental temperature changing trend is rising, and in response to a determination that t1 is less than t0, thus the environment the trend of temperature changes is decreasing. The outlet air temperature of the air conditioner refers to the real-time temperature of the cold wind blown by the air outlet of the air conditioner, which is calculated according to the indoor operating parameters and the formula in this embodiment. The formula for calculating the wind temperature is: Ta=-0.534+T1∗0.853+T2∗0.146, where T1 is the environmental temperature in the air conditioner operating environment, and T2 is the operating temperature value of the preset evaporator coil. The indoor environmental temperature is measured by a temperature sensor configured on the indoor unit of the air conditioner. The evaporator coil is also named as a copper tube. The copper tube and the aluminum foil constitute a heat exchanger with a string-type structure, and the temperature of the copper tube is measured by the temperature sensor which be set on the heat exchanger copper tube.
[0118] In this embodiment, the operating state of the air guiding strip of the air conditioner, the compressor frequency and the fan speed are adjusted, according to the set temperature, the environmental temperature changing trend and the air conditioner outlet air temperature in the operating environment. That is the corresponding breezeless mode of the air conditioner is turned on according to the set temperature, the environmental temperature changing trend and the air conditioner outlet air temperature in the operating environment. When the air conditioner enters the breezeless mode, the vertical air guiding strip is closed, and at this moment, the wind is blown out from the small hole of the closed air guiding strip, and then achieve the breezeless effect. The breezeless mode include the upper breezeless mode and the lower breezeless. Where the upper breezeless direction means that the upper vertical air guiding strip is closed, and the frequency of the compressor is limited to 35hz, when the automatic wind speed is not exceed 35%. Where the lower breezeless direction means that the lower vertical air guiding strip is closed, and the frequency of the compressor is limited to 40hz, when the automatic wind speed is not exceed 45%. No wind sense means that the lower vertical air guide bar is closed, the frequency is limited to 40hz, when the automatic wind speed does not exceed 45%. the upper breezeless mode and lower breezeless are both turned on at the same time that means that the upper vertical air guide bar and lower vertical air guide bar are both closed, and the frequency is limited to the minimum frequency when the automatic wind speed does not exceed 35%. The frequency and the wind speed of the upper breezeless wind are lower than those of the lower breezeless air, because the upper area of the air conditioner is relatively high, and the air supply distance is relatively far. Thus the cooling effect of the upper breezeless mode is better than that of the lower breezeless mode, when the breezeless mode is turned on, the cooling effect is better than that of the breezeless air, so as to the effect of reducing the frequency and the wind speed are both achieved.
[0119] In this embodiment, when the air conditioner is in the cooling mode, and the human body is close to the air conditioner, and the distance between the human body and the air conditioner is less than or equal to a preset threshold, the air conditioner may be triggered to execute the control strategy corresponding to the human body's type. Thereby the operating parameter of air conditioner is adjusted, so that the wind blown out by the air conditioner is comfortable for the human body, and avoiding people catch a cold due to they are too close to the air conditioner, and guaranteed the user's health during the use of the air conditioner.
[0120] Further, in one embodiment of the method for automatically controlling a breezeless mode of an air conditioner of the present disclosure, the S40 includes:
judging whether the upper infrared module detects an infrared signal of a human body, and whether the infrared signal of the human body is detected by the lower infrared module, in response to a determination that the air conditioner is in the cooling mode turn on;

determining there is a first type of the target obstacle, in response to a determination that the infrared module of the human body is detected by the upper infrared module.
[0121] In this embodiment, the air conditioner can be the cabinet air conditioner, and the cabinet air conditioner is configured with an infrared module group, which includes an upper infrared module group and a lower infrared module group. The distance between the upper infrared module and the bottom of the cabinet air conditioner is greater than an average height of children. A distance between the lower infrared module and the bottom of the cabinet air conditioner is less than the average height of children. And an average height of children is set according to the actual situation, for example, 1.2 meters. Referring to FIG. 3, there is depicted a scene diagram illustrating an air supply of the air conditioner of a method for automatically controlling a breezeless mode of an air conditioner according to an embodiment of the present disclosure.
[0122] In this embodiment, both the upper infrared module and the lower infrared module can receive the infrared rays in the detection range, and the detection directions of the upper infrared module and the lower infrared module are consistent or substantially the same as the air supply direction of the air conditioner. For example, the detection directions of the upper infrared module and the lower infrared module are parallel to the horizontal plane, and perpendicular to the front side of the air conditioner (the front side where the air outlet of the air conditioner located). Because of the infrared wavelength of the human body's radiation is mainly concentrated at about 10000 nm, and according to the characteristics of the infrared of the human body's radiation, an range such as from 9500 nm to 10500 nm can be set (which to be set specifically according to the actual conditions). When the infrared wavelength that detected by the lower infrared module is in the range from 9500 nm to 10500nm, and the infrared wavelength that detected by the upper infrared module is not in the range from 9500nm to 10500nm, which means that the lower infrared module detects the human body, and the upper infrared module does not detect the human body. That is, it determines that a second type of target obstacle exists, and the second type of target obstacle is the child. When the infrared wavelength that detected by the upper infrared module is in the range from 9500 nm to 10500 nm, this indicates that the upper infrared module detects the human body, that is, it is determined that a first type of target obstacle exist, and the first type of target obstacle is one adult.
[0123] In this embodiment, the upper infrared module and lower infrared module are arranged, and the target obstacle can be distinguished whether it is an adult or a child, according to the results that detected by the upper infrared module and the lower infrared module.
[0124] Further, in one embodiment of the method for automatically controlling a breezeless mode of an air conditioner of the present disclosure, the operation of "detecting whether a distance between the first type of the target obstacle and the air conditioner is less than or equal to a preset threshold", includes:
detecting the distance between the first type of target obstacle and the air conditioner through the upper infrared module; and
determining whether the distance between the first type of target obstacle and the air conditioner is less than or equal to the preset threshold.
[0125] In this embodiment, when there is a first type of target obstacle, and which is an adult, thus the upper infrared module detects an infrared signal of a human body. The infrared signal of the specific frequency is transmitted through the infrared signal transmitting diode of the infrared ranging sensor in the upper infrared module, and the infrared signal receiving diode receives the specific frequency infrared signal. And when the infrared detecting direction exists the first type of target obstacle, the infrared signal is reflected back and received by the infrared signal receiving diode. After being processed, the infrared return signal can be configured to calculate the distance L that between the first type of target obstacle and the air conditioner. Thereby the size of the distance L and the distance L0 is determined.
[0126] In this embodiment, when the distance between the target obstacle of the first type and the air conditioner is less than or equal to the preset threshold, it indicates that the first type of obstacle of an adult is nearer to the air conditioner the air conditioner needs to be controlled to avoid causing a discomfort for the adult.
[0127] In this embodiment, when there is a second type of target obstacle, and which is the children, thus the upper infrared module detects an infrared signal of a human body, and the lower infrared module detects an infrared signal of a human body. The infrared signal of the specific frequency is transmitted through the infrared signal transmitting diode of the infrared ranging sensor in the lower infrared module, and the infrared signal receiving diode receives the specific frequency infrared signal. And when the infrared detecting direction exists the second type of target obstacle, the infrared signal is reflected back and received by the infrared signal receiving diode. After being processed, the infrared return signal can be configured to calculate the distance L that between the second type of target obstacle and the air conditioner. Thereby the size of the distance L and the distance L0 is determined.
[0128] In this embodiment, when the distance between the target obstacle of the second type and the air conditioner is less than or equal to the preset threshold, it indicates that the second type of obstacle of an adult is nearer to the air conditioner the air conditioner needs to be controlled to avoid causing a discomfort for the children.

[0130] In this embodiment, the practical significance of the breezeless function is that, after the room temperature has cooled down, and reaching or approaching the target set temperature value, thus it needs to reduce the wind speed and the compressor frequency for maintaining the room temperature, and to minimize the breezeless effect of the cold air on the human body as possible. Thereby, it is required to detect whether the difference between the environmental temperature T1 and the air-conditioning set temperature Ts is less than a preset value, and the preset value is set by the user according to actual conditions. For example, the preset value to be set of 2. That is, the subsequent operations to be executed, when the difference between the environmental temperature T1 and the air-conditioning set temperature Ts is less than 2. Thereby the comfort of the air conditioner be improved, and the cooling capacity of the air conditioner also be ensured.

[0136] In which the upper breezeless direction to be turned on that means the upper vertical air guiding strip is closed, and the frequency of the compressor is limited to 35hz (which can be freely set according to the actual situation), when the automatic wind speed is not exceed 35% (which can be freely set according to the actual situation). Where the lower breezeless direction to be turned on that means the lower vertical air guiding strip is closed, and the frequency of the compressor is limited to 40hz (which can be freely set according to the actual situation), when the automatic wind speed is not exceed 45% (which can be freely set according to the actual situation). No wind sense means that the lower vertical air guide bar is closed, the frequency is limited to 40hz, when the automatic wind speed does not exceed 45%. The upper breezeless mode and lower breezeless are both turned on is closed at the same time that means that the upper vertical air guide bar and lower vertical air guide bar are both closed, and the frequency is limited to the minimum frequency. When the automatic wind speed does not exceed 35%. The frequency and the wind speed of the upper breezeless wind are lower than those of the lower breezeless air. Because the upper area of the air conditioner is relatively high, and the air supply distance is relatively far. Thus the cooling effect of the upper breezeless mode is better than that of the lower breezeless mode, when the breezeless mode is turned on, the cooling effect is better than that of the breezeless air, so as to the same effect of reducing the frequency and the wind speed achieved.
[0137] In this embodiment, after detected that the distance between the air conditioner and the air conditioner is less than a preset value, the corresponding automatic breezeless control operation is performed, according to the relationship between the three of the set temperature of the air conditioner, the temperature changing trend, and the outlet air temperature. The corresponding automatic breezeless control operation are mainly includes: the adjustment of the turning on and closing of the upper vertical air guiding strip and lower vertical air guiding strip, the controlling of the frequency of the compressor and the adjustment of the speed of the indoor fan.

[0139] In an optional embodiment of the present disclosure, the lower breezeless mode of the air conditioner is turned on, when the target obstacle is the second type target obstacle, and the distance L between the second type obstacle and the air conditioner is less than or equal to the threshold value of L0. And the local air temperature, the draft rate, the local airflow rate, the fan speed and the turbulence intensity in the air conditioner operating environment are firstly obtained. It obtained the theoretical target temperature, according to calculating the draft rate. And the target temperature is obtained, according to the theoretical target temperature and the set temperature. And finally the operating parameters are obtained according to the target temperature and the local air temperature.
[0140] In this embodiment, when the air conditioner is in the cooling mode, and the human body is close to the air conditioner, and the distance between the human body and the air conditioner is less than or equal to a preset threshold, the air conditioner may be triggered to execute the control strategy corresponding to the human body's type. Thereby the operating parameter of air conditioner is adjusted, so as to the wind blown out by the air conditioner is comfortable for the human body, and avoiding people catch a cold due to they are too close to the air conditioner, and guaranteed the user's health during the use of the air conditioner.
[0141] Further, in one embodiment of the method for automatically controlling a breezeless mode of an air conditioner of the present disclosure, the operation of "turning on the lower breezeless mode, obtaining the second operating parameter of the air conditioner, obtaining a second operating parameter of the air conditioner, and controlling the air conditioner to operate according to the second operating parameters, in response to a determination that the distance between the second type target obstacle and the air conditioner is less than or equal to the preset threshold", includes:

obtaining the local air temperature in the environmental parameter, calculating the difference between the local air temperature and the target temperature, obtaining the second operating parameter of the air conditioner according to the range where the difference is located, and controlling the air conditioner to operate according to the second operating parameter.
[0142] In this embodiment, after the lower breezeless being turned on, the lower air guiding strip of the air conditioner can be closed, and the air of the air conditioner is blown out from the small hole of the lower air guiding strip. Thus the user's feeling of the wind of the air conditioner is reduced.
[0143] In one embodiment of the present disclosure, the local air temperature is determined by the outlet air temperature, and according to the turn on breezeless mode, the outlet air temperature of tc is collected: tc1 is collected when the upper breezeless mode is turned on, tc2 is collected when the lower breezeless mode is turned on, and tc2 is collected when the the total breezeless mode is turned on. According to the correlation formula, the local air temperature value ta of an area with an altitude of 2.5 meters is calculated: the upper breezeless mode is turned on with the local air temperature value ta 1, the lower breezeless mode is turned on with the local air temperature value ta 2, and the total breezeless mode is turned on with the local air temperature value ta 3. Where the correlation formula between the outlet air temperature and the local air temperature is: ta=atc+b, where the ta is the local air temperature, the tc is the outlet air temperature, and a and b are both constants, and a corresponding to different types of breezeless mode are different, and b corresponding to different types of breezeless mode are different. For example, in response to a determination that the type of the breezeless mode is the lower breezeless, the correlation formula between the outlet air temperature and the local air temperature is: ta=0.2307tc+23.955. When it is determined that the type of the breezeless mode is the lower breezeless, the outlet air temperature collected by the set temperature sensor. That is, the outlet air temperature is tc, which to be substituted into the above formula to obtain the local air temperature.
[0144] In this embodiment, the draft rate is determined by the breezeless mode, of which should be preset: the draft rate DR1 of the upper breezeless mode is 5, the draft rate of the lower breezeless mode of DR2=10, and the draft rate of the total breezeless of DR3=5. For example, in response to a determination that it is determined that the type of the breezeless mode is the lower breezeless, the draft rate DR=10 is acquired.
[0145] In one embodiment of the present disclosure, the local airflow rate is related to the air duct structure, the fan speed, or the like, and which can be approximated as the local airflow rate Va only relates to the fan (such as a fan of the air conditioner, the fan in the following can also be a fan of air conditioner) speed F (F is in the range from the 1% to 100%). The relationship formula between the local airflow rate Va and the fan speed F is: Va=cF+d, in where c and d both are constants, and the value of c corresponding to different breezeless mode, the value of d corresponding to different breezeless mode. That is, the upper breezeless corresponds to c1 and d1, the lower breezeless corresponds to c2 and d2, and the total breezeless corresponds to c3 and d3. For example, in response to a determination that the type of the breezeless mode is the lower breezeless mode, the relationship formula between the local airflow rate Va and the fan speed F is: Va=0.0352F+0.1366. In response to a determination that it is determined that the type of the breezeless mode is the lower breezeless, the fan speed F can be obtained, according to substitute the local airflow rate into the above formula, for example, the local airflow rate is an initial value of 0.3 m/s.
[0146] In one embodiment of the present disclosure, the turbulence intensity is related to the air duct structure, the fan speed and the stability, and which can be approximated as that the turbulence intensity only related to the fan speed. The relationship formula between the turbulence intensity Tu and the fan speed F is: Tu=eF2+fF+g, where e, f, and g are both constants, and the value of e corresponding to different breezeless mode, the value of f corresponding to different breezeless mode, the value of g corresponding to different breezeless mode. That is the upper breezeless corresponds to e1=0, f1=0, and g1=36.4, and the lower breezeless corresponds to e2=-12.858, f2=29.244, and g2=21.424, and the total breezeless corresponds to e3=0, f3=0, and g3=29.6. For example, when the type of the breezeless mode is the lower breezeless, the relationship formula between the turbulence intensity Tu and the fan speed F is: Tu=-12.858F2+29.244F+21.424. When the type of the breezeless mode is the lower breezeless, the fan speed F is obtained, and the turbulence intensity Tu is obtained by the speed F substituted into the above formula.
[0147] In this embodiment, the set temperature is a temperature value preset by the user. For example, after turning on the air conditioner, the user will give a temperature, such as 25 °C, namely the set temperature.
[0148] In 1988, Fanger proposed a model for predicting the dissatisfaction of breezeless. Based on this model,the draft rate DR in IS07730-2005 is used to characterized the human dissatisfaction caused by the wind draft feeling. The formula of the draft rate is:
where DR is the draft rate, in response to a determination that DR is larger than 100%, and DR is equal to 100%; tas is the theoretical target temperature, and the sign for temperature is °C; Va is the local airflow rate, m/s; Tu is the turbulence intensity.
[0149] tas of the theoretical target temperature is obtained, in response to a determination that the draft rate DR, the local airflow rate Va, and the turbulence intensity into the above formula.
[0150] In one embodiment of the present disclosure, when the target obstacle is a child, the target temperature can be obtained according to the theoretical target temperature and the set temperature:
When the set temperature is less than 24 °C, and the theoretical target temperature of tas is less than 24 °C, the target temperature is set as 24 °C. The target temperature is set as 29 °C, when the theoretical target temperature of tas is greater than 29 °C. When the theoretical target temperature is at the range from 24 °C to 29 °C, the theoretical target temperature is set as the target temperature.
[0151] When the set temperature is greater than or equal to 24 °C, and less than or equal to 28 °C, and the theoretical target temperature of tas is less than 24 °C, thus the target temperature is set as 24 °C. When the theoretical target temperature of tas is greater than 29 °C, thus the target temperature is set as 28 °C. When the theoretical target temperature is between 24 °C and 29 °C, then the theoretical target temperature is the target temperature.
[0152] When the set temperature is greater than 28 °C, and the theoretical target temperature of tas is less than 24 °C, thus the target temperature is set as 24 °C. When the theoretical target temperature of tas is greater than 29 °C, thus the target temperature is set as 29 °C. when the theoretical target temperature is between 24 °C and 29 °C, then the theoretical target temperature is the target temperature.
[0153] After obtaining the target temperature, the target temperature of tas is compared with the local air temperature of the ta. First, whether the difference between tas and ta is greater than a preset value is detected. For example, whether the difference between tas and ta is greater than 1 is detected. And when the difference between tas and ta is not exceed 1, thus the parameter of the air conditioner is maintained. When the difference between tas and ta is greater than 1, thus there are two cases, one case is that tas is greater than ta, and the difference is greater than 1; and another one is that tas is less than ta, and the difference is greater than 1. That is, the difference between ta and tas have two ranges, in the which the first range is (1, ∞), that is, tas is less than ta, and the difference is greater than 1. And in the which the second range is (-∞, -1), that is, tas is greater than ta, And the difference is greater than 1. When the difference between tas and ta is in the first range, thus the compressor frequency is increased by a preset value. For example, the compressor frequency is increased by 1 hz, and the running time is 3 min. In response to a determination that the difference between tas and ta is in the second range, thus the compressor frequency is lowered by a preset value, such as 1 hz, and the running time is 3 min. In another embodiment of the present disclosure, when the compressor frequency is lowered to a minimum value. For example, the minimum value is set as 20 hz, the initial value of the local airflow rate of 0.3 m/s is lowered by a preset value, for example, by which the preset value of 0.1. That is, when the compressor frequency is lowered to 20 hz, thus the local airflow rate is lowered to 0.2 m/s, and the calculated fan speed F is 1.8011, according to the lower breezeless. And the relationship formula between the local airflow rate Va and the fan speed F: Va=0.0352F+0.1366. And running with the compressor frequency of 20hz and the fan speed of 1.8011, and the running time is 3 min at this moment (the running time that can be maintained according to the actual needs, and the running time is not be limited here).
[0154] In this embodiment, when it is detected that the distance between the children and the air conditioner is less than a preset value, the lower breezeless mode of the air conditioner is turned on. And the operating parameter of the air conditioner is automatically controlled according to the environmental parameter of the air conditioner operating environment. Thereby the air conditioner achieves the adaptive control mode in the breezeless mode, so as to give the users a better using experience.
