DETAILED DESCRIPTION
[0019] Examples will be described herein in detail, and represented in the accompanying figures. When the following description involves the accompanying figures, the same numerals in different accompanying figures indicate the same or similar elements unless otherwise indicated. The embodiments described in the following examples do not represent all embodiments consistent with the present disclosure.
[0020] During the use of the drying system of the washing equipment, the airflow rate is often reduced due to the wear of a motor shaft of the blower, and the accumulation of lint in an impeller of the blower, the heating air ducts, or the condensation channels, resulting in an increase in the resistance of the system, and the drying effect is affected.
[0021] The drying method provided in the embodiments of the present disclosure is applied to a scenario in which washing equipment provided with a drying system dries washings.
[0022] In the washing equipment provided with the drying system, the drying system includes a blower, heating tubes, heating air ducts, and condensation channels. During the use of the drying system, the airflow rate will decrease due to the wear of a motor shaft of the blower, and the accumulation of lint in an impeller of the blower, the heating air ducts, or the condensation channels, and consequently the drying efficiency of the drying system is affected. In such a case, it is needed for a user to manually clean and maintain the drying device to work normally. However, the current washing equipment provided with a drying system does not have a solution for detecting and prompting a decrease in the resistance of the drying system during use.
[0023] In view of this, the present disclosure proposes a drying method. During the washing equipment provided with a drying system dries washings, a resistance state of the drying system can be determined based on the weight of the washings and the temperature of the drying system, and the drying system is adjusted for drying the washings based on the resistance state.
[0024] FIG. 1 illustrates a flow chart of a drying method according to an example. As shown in FIG. 1, the method includes step S101 and step S102.
[0025] In step S101, a weight of washings put into the washing equipment is determined and a temperature detected by a temperature sensor arranged in the drying system is acquired, in response to a drying program being started for the drying system.
[0026] In an embodiment of the present disclosure, after finishing the washing process, the drying system enters a drying process to dry the washings, where the temperature sensor for detecting the temperature of the drying system is arranged in the vicinity of the heating device, and configured to detect the temperature in the vicinity of the heating device in real time.
[0027] In step S102, a resistance state of the drying system is determined based on the weight and the temperature, and the drying system is controlled to dry the washings based on the resistance state.
[0028] The resistance state of the drying system is used for representing an airflow rate during the drying system dries the washings.
[0029] In the embodiments of the present disclosure, the heat of the heating device in the drying system is transferred to the washings by means of air flow in a drying tunnel, and the air flow rate in the drying tunnel is the airflow rate of the drying system. During the use of the drying system, the airflow rate will decrease due to the wear of a motor shaft of a blower, and the accumulation of lint in an impeller of the blower, heating air ducts, or condensation channels, resulting in a decrease in the drying efficiency of the drying system. If the airflow rate of the drying system is greater than or equal to the preset airflow rate threshold, the resistance state of the drying system is considered to be a normal state; if the airflow rate of the drying system is less than the preset airflow rate threshold, the resistance state of the drying system is considered to be an abnormal resistance state.
[0030] In the embodiments of the present disclosure, during the washing equipment provided with the drying system dries the washings, the resistance state of the drying system is detected, and the washings are dried based on the resistance state of the drying system.
[0031] In the following embodiments of the present disclosure, a method for determining a resistance state of a drying system according to the present disclosure is described.
[0032] FIG. 2 illustrates a flow chart of a method for determining a resistance state of a drying system according to an example. As shown in FIG. 2, the method includes step S201 to step S203.
[0033] In step S201, a current weight level corresponding to a weight is determined, and a current temperature rise rate is determined based on the acquired temperature.
[0034] In the embodiments of the present disclosure, a plurality of weight levels are preset. Each weight level corresponds to a different weight interval, and upon determining the weight level of washings, the corresponding weight level is determined based on the weight interval in which the weight of the washings is located. For example, a plurality of weight levels are respectively preset as: level 1 (0-5 KG), level 2 (5-10 KG), and level 3 (10-15 KG), and if the weight of the washings is determined as 7.4 KG, the corresponding weight level is level 2. It is understood that the division of the weight levels may be set based on actual needs, and more weight levels may be set to improve precision.
[0035] In step S202, a current temperature rise rate threshold corresponding to the current weight level is determined based on the corresponding relationship between a weight level and a temperature rise rate threshold.
[0036] In the embodiments of the present disclosure, the weight of the washings affects the temperature rise rate, and the greater the weight of the washings, the more moisture in the washings, the more time the drying system uses to dry the moisture in the washings, and the lower the temperature rise rate, so there is a corresponding relationship between the weight level and the temperature rise rate threshold.
[0037] In step S203, a resistance state of the drying system is determined based on the current temperature rise rate and the current temperature rise rate threshold.
[0038] In the embodiments of the present disclosure, the airflow rate of the drying system may be indirectly determined based on observing the temperature rise rate of the washings. The temperature sensor of the drying system is arranged in the vicinity of the heating device, and the higher the airflow rate, the faster the heat is taken away from the vicinity of the heating device, and the lower the temperature rise rate in the vicinity of the heating device. Similarly, the lower the airflow rate, the higher the temperature rise rate in the vicinity of the heating device. Moreover, the airflow rate in the drying system reflects the resistance state of the drying system, and in the case of resistance abnormality, the airflow rate will decrease. Therefore, the magnitude of the temperature rise rate reflects the resistance state of the drying system. In order to clearly determine whether the resistance state of the drying system is abnormal, a temperature rise rate threshold may be set. Considering that the temperature rise rate is affected by the weight of the washings, a corresponding temperature rise rate threshold may be set for each weight level. The resistance state of the drying system is determined based on the current temperature rise rate and the corresponding current temperature rise rate threshold.
[0039] In the following embodiments of the present disclosure, a method for determining a resistance state of a drying system according to the present disclosure is further described.
[0040] FIG. 3 illustrates a flowchart of a method for determining a resistance state of a drying system according to another example. As shown in FIG. 3, the method includes step S301, step S302A, and step S302B.
[0041] In step S301, a current temperature rise rate is determined, and a current temperature rise rate threshold is also determined.
[0042] In the embodiments of the present disclosure, if the resistance state of the drying system is normal, for the same weight of the washings, the temperature rise rate cannot be kept constant and will fluctuate within a certain range during the drying system carries out the drying. The reasons for this fluctuation are comprehensive. For example, for the same weight of the washings, the moisture contents in the washings may be different, and the corresponding temperature rise rates also may be different. It is unreasonable to attribute the conventional fluctuation of the temperature rise rate to an abnormal resistance state of the drying system, so it is needed to set different temperature rise rate thresholds based on different weight levels.
[0043] In the embodiments of the present disclosure, after the weight of the washings is determined, the corresponding weight level is determined, and the corresponding temperature rise rate threshold is determined based on the corresponding relationship between the weight level of the washings and the different temperature rise rate thresholds. And the current temperature rise rate is determined based on the temperature rise value during a certain period of time.
[0044] In step S302A, the resistance state of the drying system is determined as an abnormal resistance state, in response to the current temperature rise rate being greater than the current temperature rise rate threshold.
[0045] In the embodiments of the present disclosure, if the current temperature rise rate is greater than the current temperature rise rate threshold, it indicates that the airflow rate of the drying system decreases, the heat transfer efficiency of the drying tunnel decreases, and the resistance of the drying system is abnormal.
[0046] In step S302B, the resistance state of the drying system is determined as a normal state, in response to the current temperature rise rate being less than or equal to the current temperature rise rate threshold.
[0047] In the embodiments of the present disclosure, if the current temperature rise rate is less than or equal to the current temperature rise rate threshold, it indicates that the airflow rate of the drying system is normal, the heat transfer efficiency of the drying tunnel is within a normal range, and the resistance state of the drying system is normal.
[0048] In the embodiments of the present disclosure, the washing equipment will make a corresponding response action based on the change in the resistance state of the drying system.
[0049] FIG. 4 illustrates a flow chart of a method for drying washings according to an example. As shown in FIG. 4, the method includes step S401, step S402A, and step S402B.
[0050] In step S401, a resistance state of the drying system is determined based on the current temperature rise rate and the current temperature rise rate threshold.
[0051] In step S402A, the drying system is maintained to dry the washings and sending prompt information, in response to the resistance state of the drying system being an abnormal resistance state.
[0052] The prompt information is used for prompting to clean the drying system. The prompt information may be one or more of a ringtone, a voice, and a vibration in a special frequency. The embodiments of the present disclosure do not limit a specific realization form of the prompt information, as long as the prompt information may provide a reminder effect. It could be understood that the drying process of the drying system will be accompanied by noises. And when the prompt information is sent, the drying system maintains normal work, and the noise sent by the drying system affects the user's reception of the prompt information, so it is possible to send the prompt information after the drying system finished drying according to demands. Moreover, based on the Internet of Things technology, the washing equipment can be connected wirelessly with a terminal, the user can monitor the drying state through the terminal, and the prompt information can be displayed to the user through the terminal.
[0053] In the embodiments of the present disclosure, the abnormal resistance state of the drying system may affect the drying efficiency and make the drying efficiency reduce, and the drying system can still work normally. Therefore, after the abnormal resistance state of the drying system is detected, the normal work of the drying system is still maintained.
[0054] In step S402B, the drying system is maintained to dry the washings, in response to the resistance state of the drying system being a normal state.
[0055] In the embodiments of the present disclosure, during the resistance state of the drying system is abnormal, the prompt information is sent, so as to remind the user to clean and maintain the drying system and the drying system is controlled to continue drying the washings; during the resistance state of the drying system is normal, the working state is maintained and no prompt information is sent. The drying efficiency of the drying system is ensured.
[0056] In the following embodiments of the present disclosure, a method for determining a corresponding relationship between a weight level and a temperature rise rate threshold according to the present disclosure is described hereinafter.
[0057] FIG. 5 illustrates a flow chart of a method for determining a corresponding relationship between a weight level and a temperature rise rate threshold, according to an example. As shown in FIG. 5, the method includes step S501, step S502A, step S502B, and step S503.
[0059] In step S502A, during the resistance state of the drying system is a normal state, a first time for the temperature sensor to rise from a first temperature to a second temperature is determined for each weight level, and a first temperature rise rate threshold corresponding to each weight level is determined based on the first temperature, the second temperature and the first time.
[0060] In step S502B, during the resistance state of the drying system is an abnormal resistance state, a second time for the temperature sensor to rise from a first temperature to a second temperature is determined for each weight level, and a second temperature rise rate threshold corresponding to each weight level is determined based on the first temperature, the second temperature and the second time.
[0061] In step S503, a temperature rise rate threshold corresponding to each weight level is determined based on the first temperature rise rate threshold and the second temperature rise rate threshold corresponding to each weight level.
[0062] The temperature rise rate threshold is greater than the first temperature rise rate threshold and less than or equal to the second temperature rise rate threshold.
[0063] In the embodiments of the present disclosure, the first temperature rise rate threshold during the resistance state of the drying system is normal and the second temperature rise rate threshold during the resistance state of the drying system is abnormal are respectively acquired for the same weight level. A value between the first temperature rise rate threshold and the second temperature rise rate threshold is taken as the temperature rise rate threshold based on an actual situation. In order to determine the second temperature rise rate threshold, the resistance state of the drying system could be caused to be abnormal by manual means. By this way, a temperature rise rate threshold corresponding to each weight level is determined.
[0064] In an example of the present disclosure, in a case a weighed load of the washings is in gear 2, and the resistance is normal, it takes 180 seconds for the value of the temperature sensor to rise from 30°C to 80°C during drying. That is, the temperature rise rate k1 is 0.278. After the resistance increases, the airflow rate decreases, and the value of the temperature sensor rises from 30°C to 80°C in 100 seconds, that is, the temperature rise rate k2 increases to 0.5. Therefore, in the case that the gear of the weight of washings is 2, and the temperature rise rate k calculated based on the detected value of the temperature sensor is greater than a certain value (which can be a certain value between 0. 278 and 0.5), it is considered that the resistance of the drying system is too great and the airflow rate is reduced, thus remind the user to clean the drying system.
[0065] In the embodiments of the present disclosure, for a plurality of weight levels, corresponding temperature rise rate thresholds are determined respectively based on different temperature rise rates for different weights of washings.
[0066] An example of the present disclosure illustrates a method for drying washings, as shown in a schematic diagram of a drying method in FIG. 6, the method including the followings:
1. start drying.
If a drying program is triggered to start, washing equipment provided with a drying
system, such as a washing machine provided with a drying system such as a washer-dryer,
is triggered to start drying.
2. the weight of the clothes is judged.
The clothes are weighed to judge the weight of the clothes in a drum, and determine
the corresponding weight level as m. The weight level-temperature rise rate threshold
table is preset, and the temperature rise rate threshold is a marginal value for judging
whether the airflow rate is abnormal.
3. the initial temperature detected by the temperature sensor is recorded.
Before the drying system starts to dry, and before a heating element of the drying
system starts to work, an initial temperature near the heating element is detected
by means of the temperature sensor, and the initial temperature detected by the temperature
sensor is recorded as T1.
4. a temperature detected by the sensor after a certain period of time is recorded.
After the heating element of the drying system starts working, the temperature detected
by the temperature sensor after a certain period of time t is recorded as T2.
5. the temperature rise rate is calculated.
(T2-T1)/t is calculated based on the initial temperature T1, the temperature T2 after
a certain period of time, and the heating time t. The result of the calculation is
the temperature rise rate, and is recorded as the current temperature rise rate k.
6. whether the temperature rise rate exceeds the corresponding temperature rise rate
threshold under the condition of corresponding weight is judged.
The corresponding temperature rise rate threshold at the current weight level is determined,
based on the preset weight level-temperature rise rate threshold table, and the current
temperature rise rate k is compared with the corresponding temperature rise rate threshold.
7. if the current temperature rise rate k exceeds the corresponding temperature rise rate threshold, it indicates that the heat of the heating element is not normally transferred to the clothes to be dried, and the airflow rate of the drying system is less than the normal threshold, control prompting the user to clean up the drying system and continue drying.
[0067] If the current temperature rise rate k does not exceed the corresponding temperature rise rate threshold, it indicates that the heat of the heating element is normally transferred to the clothes to be dried, and the airflow rate of the drying system is normal, the drying system continues drying, and the user is not prompted to clean the drying system.
[0068] In the embodiments of the present disclosure, a plurality of weight levels are preset, and corresponding temperature rise rate thresholds are set. Upon starting the drying program, the weight of the washings is detected, and the weight level of the washings is determined. After drying for a period of time, a current temperature rise rate is determined based on a change in temperature in the vicinity of the heating device. If the current temperature rise rate is greater than the corresponding current temperature rise rate threshold, the resistance state of the drying system is determined to be in an abnormal resistance state, the drying process is maintained, and the user is reminded to clean the drying system; if the current temperature rise rate is less than or equal to the corresponding current temperature rise rate threshold, the resistance of the drying system is determined to be normal, the drying process is maintained, and prompt information is not sent. By means of the present disclosure, a method for detecting a resistance state of a drying system and prompting a user to clean the drying system is provided for washing equipment provided with a drying system.
[0069] Based on the same conception, the embodiments of the present disclosure also provides a drying device 100.

A person skilled in the art may use different approaches for each particular application to implement the described function. However, such implementations should not be considered outside the scope of the technical solutions of the embodiments of the present disclosure.
