DETAILED DESCRIPTION



[0031] Below is detailed description of embodiments of the present disclosure, which are shown in the drawings. Throughout the drawings, same or similar reference signs identify same or similar elements or elements having same or similar functions. The embodiments described below in conjunction with the drawings are illustrative, i.e., the embodiments are intended to illustrate the present disclosure, but not to limit the present disclosure.

[0032] As shown in combination of Figs. 1 and 2, a control method of an embodiment of the present disclosure may be applied to a dishwasher 100. The dishwasher 100 includes a housing 110, a fan 120, a humidity detection unit 140, a heating device 170, and a feeding device 180 for the dish-brightening agent. The housing 110 is provided with a working chamber 111 and an air flue 112 for keeping the working chamber 111 in communication with the outside, and the humidity detection unit 140 is configured to detect a humidity of the working chamber 111. The fan 120 is configured to establish an airflow passing through the heating device 170 and the air flue 112 to ventilate the working chamber 111. The control method includes steps of:

S151: determining whether a dish-brightening agent is fed by the feeding device 180;

S152: controlling the humidity detection unit 140 to detect a humidity after the dishwasher 100 finishes washing;

S153: controlling the fan 120 to run for a second predefined time after stopping running for a first predefined time according to the humidity after the dishwasher 100 finishes washing when the dish-brightening agent is fed by the feeding device 180, wherein the humidity is negatively correlated to the first predefined time, and the humidity is positively correlated to the second predefined time; and

S154: controlling the fan 120 and the heating device 170 to run for a fourth predefined time after stopping running for a third predefined time according to the humidity after the dishwasher 100 finishes washing when no dish-brightening agent is fed by the feeding device 180, wherein the humidity is negatively correlated to the third predefined time, and the humidity is positively correlated to the fourth predefined time.



[0033] Again, with reference to Fig. 2, the dishwasher 100 of an embodiment of the present disclosure includes a housing 110, a fan 120, a humidity detection unit 140, a processor 150, a heating device 170, and a feeding device 180 for the dish-brightening agent. The housing 110 is provided with a working chamber 111 and an air flue 112 for keeping the working chamber 111 in communication with the outside. The fan 120 is configured to establish an airflow passing through the air flue 112 to ventilate the working chamber 111. The humidity detection unit 140 is configured to detect the humidity of the working chamber 111. The processor 150 is configured to:

determine whether a dish-brightening agent is fed by the feeding device 180;

control the humidity detection unit 140 to detect a humidity after the dishwasher 100 finishes washing;

control the fan 120 to run for a second predefined time after stopping running for a first predefined time according to the humidity after the dishwasher 100 finishes washing when the dish-brightening agent is fed by the feeding device 180, wherein the humidity is negatively correlated to the first predefined time, and the humidity is positively correlated to the second predefined time; and

control the fan 120 and the heating device 170 to run for a fourth predefined time after stopping running for a third predefined time according to the humidity after the dishwasher 100 finishes washing when no dish-brightening agent is fed by the feeding device 180, wherein the humidity is negatively correlated to the third predefined time, and the humidity is positively correlated to the fourth predefined time.



[0034] That is to say, the control method of an embodiment of the present disclosure may be implemented by the dishwasher 100 of the embodiment of the present disclosure, wherein steps S151, S152, S153, and S154 may be implemented by the processor 150.

[0035] The control method for dishwasher 100 and the dishwasher 100 of the embodiment of the present disclosure control the fan 120 and heating device 170 according to whether the dish-brightening agent is fed and the humidity of the working chamber 111, thereby reducing the water vapor content of the working chamber 111.

[0036] Again, with reference to Fig. 1, the step S151 of the embodiment of the present disclosure is executed after the step S152. It is to be understood that, in other embodiments, the step S151 may be executed before the step S152, which is not specifically limited herein.

[0037] In a certain embodiment, due to the space limitation of the working chamber 111, for example, the working chamber 111 is small, the humidity detection unit 140 may not be directly installed in the working chamber 111, thus the humidity detection unit 140 may be installed in the air flue 112 to detect the humidity in the air flue 112 using the humidity detection unit 140. The working chamber 111 refers to a component in the dishwasher 100 for placing dishes and washing dishes, and is also called an inner container. In some embodiments, the humidity in the air flue 112 may be regarded as the humidity of the working chamber 111.

[0038] In some embodiments, the humidity detection unit 140 may be directly disposed in the working chamber 111 to accurately obtain the humidity of the working chamber 111, which is not specifically limited herein.

[0039] In some embodiments, the fan 120 may be disposed inside the dishwasher 100 or outside the dishwasher 100, which is not specifically limited herein. In an embodiment, the fan 120 is disposed adjacent to the heating device 170, so that the fan 120 may blow a thermal energy generated by the operation of the heating device 170 to the working chamber 111.

[0040] In some embodiments, the dishwasher 100 finishing washing means that the dishwasher 100 has finished the washing program, which generally includes several programs such as pre-washing, main washing, rinsing and drying. The dishwasher 100 finishing washing generally means that the drying program has ended. The steps S151, S152, S153, and S154 of the embodiment of the present disclosure may be regarded as maintenance programs, and the steps S151, S152, S153, and S154 may be repeatedly executed repeatedly to keep the work chamber 111 dry.

[0041] In some embodiments,, the humidity detection unit 140 includes a humidity sensor.

[0042] As such, the humidity sensor may be used to obtain the humidity quickly.

[0043] Specifically, the humidity sensor may refer to a device for measuring the relative humidity of the air. The humidity detection unit 140 is generally configured to measure the relative humidity.

[0044] Specifically, the dish-brightening agent refers to a product for reducing the surface tension of water and avoiding water marks on the dishes after the dishwasher 100 finishes washing. It is to be understood that when the dishwasher 100 performs washing, basically no water marks will be left on the dishes if the dish-brightening agent is fed by the feeding device 180, without using the heating device 170 to evaporate the water marks, so the heating device 170 may be controlled to be turned off to reduce the power consumption of the dishwasher 100; when the dishwasher 100 performs washing, water marks will be left on the dishes if no dish-brightening agent is fed by the feeding device 180, so the heating device 170 may be controlled to work, so that the water marks on the dishes may be evaporated into water vapor, and further the fan 120 may discharge the water vapor from the working chamber 111.

[0045] It is to be understood that when the humidity is relatively small, indicating that the water vapor in the dishwasher 100 is not easy to condense into water droplets, the fan 120 may be controlled to stop running for a longer time (that is, the first predefined time and the third predefined time are both longer) and run for a shorter time (that is, the second predefined time and the fourth predefined time are both short); when the humidity is relatively large, indicating that the water vapor in the dishwasher 100 is easy to condense into water droplets, the fan 120 may be controlled to stop running for a short time (that is, the first predefined time and the third predefined time are both shorter) and run for a longer time (that is, the second predefined time and the fourth predefined time are both longer), thereby removing the water vapor in the dishwater 100, further preventing the water vapor from condensing into droplets.

[0046] In some embodiments, when the humidity values are the same, the first predefined time and the third predefined time may be the same or different, and the second predefined time and the fourth predefined time may be the same or different, which are not specifically limited herein.

[0047] In some embodiments, the heating device 170 includes a heating pipe. As such, the heating device 170 may be used to generate the thermal energy.

[0048] In some embodiments, the feeding device 180 includes a feeding detection unit 182, and the feeding detection unit 182 includes a pressure sensor. As such, whether a dish-brightening agent is fed by the feeding device 180 may be determined by an output of the feeding detection unit 182.

[0049] Specifically, the feeding detection unit 182 may be a pressure sensor, and then by placing the pressure sensor in the feeding device 180, such as at the bottom of the feeding device 180, whether the dish-brightening agent is fed may be determined through the changes in pressure generated by the dish-brightening agent stored in the feeding detection device 180. For example, when the pressure detected by the pressure sensor becomes smaller, it indicates that the feeding device 180 may feed the dish-brightening agent into the dishwasher.

[0050] In some embodiments, the feeding detection unit 182 may also be an infrared sensor. The infrared sensor determines whether the dish-brightening agent fed into the device 180 is reduced by the emission and the return time of infrared light.

[0051] In some embodiments, the feeding device 180 includes a switch configured to control the entry and exit of the dish-brightening agent, and the state of the switch may also be used to determine whether the dish-brightening agent is fed by the feeding device 180.

[0052] It should be noted that the dish-brightening agent is generally used in the washing program of the dishwasher 100 such as a rinsing program. If the dish-brightening agent is used during the rinsing program, it can be determined that the dish-brightening agent is fed by the feeding device 180, and if the dish-brightening agent is not used during the rinsing program, it can be determined that no dish-brightening agent is fed by the feeding device 180.

[0053] With reference to Fig. 3, in some embodiments, before the dishwasher 100 finishes washing, the method includes steps of:

S155: controlling the fan 120 to stop running for a seventh predefined time after stopping running for a fifth predefined time and after running for a sixth predefined time when the dish-brightening agent is fed by the feeding device 180; and

S156: controlling the fan 120 and the heating device 170 to stop running for a tenth predefined time after stopping running for an eighth predefined time and after running for a ninth predefined time when no dish-brightening agent is fed by the feeding device 180.



[0054] Again, with reference to Fig. 2, in some embodiments, the processor 150 is configured to:

control the fan 120 to stop running for a seventh predefined time after stopping running for a fifth predefined time and after running for a sixth predefined time when the dish-brightening agent is fed by the feeding device 180; and

control the fan 120 and the heating device 170 to stop running for a tenth predefined time after stopping running for an eighth predefined time and after running for a ninth predefined time when no dish-brightening agent is fed by the feeding device 180.



[0055] That is to say, the steps S155 and S156 may be implemented by the processor 150.

[0056] As such, dishes in the dishwasher 100 may be subjected to drying treatment.

[0057] Specifically, before the dishwasher 100 finishes washing, the dishwasher 100 generally includes a drying program, and the water vapor content in the working chamber 111 may be greatly reduced by the drying program. When the dish-brightening agent is fed by the feeding device 180, the drying program of the dishwasher 100 may be implemented by controlling the fan 120 to stop running for the fifth predefined time and run for the sixth predefined time, and when no dish-brightening agent is fed by the feeding device 180, the drying program of the dishwasher 100 may be implemented by controlling the fan 120 to stop running for the eighth predefined time and run for the ninth predefined time. That is to say, the drying program of the dishwasher 100 may be running for a period of time (a sixth predefined time or a ninth predefined time) after the fan 120 is controlled to stop running for a period of time (the fifth predefined time or the eighth predefined time). It can be understood that in order to greatly reduce the water vapor content in the working chamber 111, the fifth predefined time may be much shorter than the sixth predefined time, and the eighth predefined time may be much shorter than the ninth predefined time, and the fan 120 may be controlled to work for the fifth predefined time and the sixth predefined time in multiple times or the fan 120 may be controlled to work for an eighth predefined time and a ninth predefined time in multiple times.

[0058] It should be noted that the steps S151, S152, S153, and S154 of the embodiment of the present disclosure may also used to dry the air in the working chamber 111, but generally a long time is required, so the fan 120 may be controlled to stop running for a period of time (the fifth predefined time or the eighth predefined time) and run for a period of time (the sixth predefined time or the ninth predefined time) to dry the air in the working chamber 111 in a short time. In addition, after the working chamber 111 is dried by the fan 120, the water vapor content of the working chamber 100 is low in a short time, so the fan 120 may be controlled to stop running for the seventh predefined time or the tenth predefined time, such as 60 minutes, thereby reducing the power consumption of the dishwasher 100.

[0059] It is to be understood that the fifth predefined time and the eighth predefined time may be the same or different, the sixth predefined time and the ninth predefined time may be the same or different, and the seventh predefined time and the tenth predefined time may be the same or different, which are not specifically limited herein.

[0060] In some embodiments, the fifth predefined time and the eighth predefined time are both about 5 minutes, the sixth predefined time and the ninth predefined time are both about 40 minutes, and the seventh predefined time and the tenth predefined time are both about 60 minutes.

[0061] As such, the air in the working chamber 111 may be dried.

[0062] In some embodiments, the fifth predefined time and the eighth predefined time are the same, the sixth predefined time and the ninth predefined time are the same, and the seventh predefined time and the tenth predefined time are the same. Specifically, when the fan 120 is controlled to dry the dishwasher 100, generally, the fan 120 first stops running for the shorter fifth predefined time or the eighth predefined time, such as 0 to 10 minutes, preferably 5 minutes, then runs for a longer sixth predefined time or the ninth predefined time, such as 30 to 60 minutes, preferably 40 minutes, thereby fully taking away the water vapor in the working chamber 111 and further ensuring the drying of the working chamber 111. After the working chamber 111 is dried by the fan 120, the water vapor content of the working chamber 111 is low, then the fan 120 may stop running for the seventh predefined time or the tenth predefined time, such as 50 to 70 minutes, preferably 60 minutes, and after stopping running for 60 minutes, the humidity may be detected and the fan 120 may be controlled to operate to execute the maintenance program of the dishwasher 100 according to the control method of the embodiment of the present disclosure.

[0063] With reference to Fig. 4, in some embodiments, the step S151 includes steps of:

S1511: controlling the fan 120 to run for the eleventh predefined time after the dishwasher 100 finishes washing and before the first predetermined time when the dish-brightening agent is fed by the feeding device 180;

S1512: controlling the fan 120 and the heating device 170 to run for the twelfth predefined time after the dishwasher 100 finishes washing and before the third predetermined time when no dish-brightening agent is fed by the feeding device 180; and

S1513: controlling the humidity detection unit 140 to detect the humidity within the eleventh predefined time or the twelfth predefined time.



[0064] Again, with reference to Fig. 2, in some embodiments, the processor 150 is configured to:

control the fan 120 to run for the eleventh predefined time after the dishwasher 100 finishes washing and before the first predetermined time when the dish-brightening agent is fed by the feeding device 180;

control the fan 120 and the heating device 170 to run for the twelfth predefined time after the dishwasher 100 finishes washing and before the third predetermined time when no dish-brightening agent is fed by the feeding device 180; and

control the humidity detection unit 140 to detect the humidity within the eleventh predefined time or the twelfth predefined time.



[0065] That is to say, the steps S1511, S1512 and S1513 may be implemented by the processor 150.

[0066] As such, the humidity detected by the humidity detection unit 140 may be made substantially consistent with the humidity of the working chamber.

[0067] Specifically, the humidity detection unit 140 may be disposed in the air flue 112, and when the humidity detection unit 140 works, the fan 120 may be controlled to run if the dish-brightening agent is fed by the feeding device 180; the fan 120 and the heating device 170 may be controlled to run simultaneously if no dish-brightening agent is fed by the feeding device 180; then the fan 120 may drive the air in the working chamber 111 to flow, and further the air in the air flue 112 may be regarded as the air in the working chamber 111, that is, the humidity detected by the humidity detection unit 140 may be regarded as the humidity of the working chamber 111.

[0068] It is to be understood that the eleventh predefined time is between the end of washing of the dishwasher 100 and the first predefined time, and in some embodiments, the eleventh predefined time may refer to the last period of the seventh predefined time, such as the last 20 seconds of the seventh predefined time. In an embodiment, just when the washing program ends, the eleventh predefined time may refer to the last period of the seventh predefined time, such as 20 seconds. In another embodiment, when the steps S151, S152, S153, and S154 are executed cyclically and the previous first predefined time and the second predefined time have just ended, the eleventh predefined time may refer to the last period of the previous second predefined time, such as 20 seconds.

[0069] It is to be understood that the twelfth predefined time is between the end of washing of the dishwasher 100 and the third predefined time, and in some embodiments, the twelfth predefined time may refer to the last period of the tenth predefined time, such as the last 20 seconds of the tenth predefined time. In an embodiment, just when the washing program ends, the twelfth predefined time may refer to the last period of the tenth predefined time, such as 20 seconds. In another embodiment, when the steps S151, S152, S153, and S154 are executed cyclically and the previous third predefined time and the fourth predefined time have just ended, the twelfth predefined time may refer to the last period of the previous fourth predefined time, such as 20 seconds.

[0070] It is to be understood that controlling the humidity detection unit 140 to detect the humidity within the eleventh predefined time or the twelfth predefined time refers to controlling the humidity detection unit 140 to detect the humidity within the eleventh predefined time when the dish-brightening agent is fed by the feeding device 180, and controlling the humidity detection unit 140 to detect the humidity within the twelfth predefined time when no dish-brightening agent is fed by the feeding device 180.

[0071] It should be noted that in order to ensure that the humidity detected by the humidity detection unit 140 is substantially the same as the humidity of the working chamber 111 when no dish-brightening agent is fed by the feeding device 180, generally, the twelfth predefined time is greater than the eleventh predefined time, e.g., the eleventh predefined time may be 20 seconds, and the twelfth predefined time may be 1 minute. In some embodiments, the eleventh predefined time and the twelfth predefined time may also be the same.

[0072] With reference to Fig. 5, in some embodiments, the step S151 includes steps of:

S1514: controlling the humidity detection unit 140 to perform a plurality of detections to obtain a plurality of initial humidity values; and

S1515: processing the plurality of initial humidity values to obtain the humidity, the humidity being an intermediate value or an average value of the plurality of initial humidity values.



[0073] Again, with reference to Fig. 2, in some embodiments, the processor 150 is configured to:

control the humidity detection unit 140 to perform a plurality of detections to obtain a plurality of initial humidity values; and

process the plurality of initial humidity values to obtain the humidity, the humidity being an intermediate value or an average value of the plurality of initial humidity values.



[0074] That is to say, the steps S1514 and S1515 may be implemented by the processor 150.

[0075] As such, the accuracy of the humidity may be ensured.

[0076] It is to be understood that the humidity detection unit 140 may detect to obtain an initial humidity, a plurality of initial humidity values may be obtained through a plurality of detections by the humidity detection unit 140, and the humidity may be obtained by processing the plurality of initial humidity values. Specifically, the method of processing the plurality of initial humidity values to obtain the humidity includes methods such as taking the average value of the plurality of initial humidity values as the humidity, or taking the median value of the plurality of initial humidity values as the humidity, etc., which are not specifically limited herein.

[0077] In addition, the plurality of initial humidity values may be to obtain an initial humidity at intervals, for example, to obtain an initial humidity at intervals of 5 seconds within 20 seconds or an initial humidity at intervals of 20 seconds within 1 minute, and so on.

[0078] With reference to Fig. 6, in some embodiments, the fan 120 has a plurality of fans, and the plurality of fans 120 is configured to be cooperated to establish an airflow passing through the air flue 112 to ventilate the working chamber 111.

[0079] As such, the dehumidifying effect of the dishwasher 100 may be achieved to a large extent.

[0080] It is to be understood that in order to enhance the dehumidification capacity of the working chamber 111, the fan 120 has a plurality of fans, that is, the dishwasher 100 includes a plurality of fans 120, so that the plurality of fans 120 may be operated simultaneously to enhance the air circulation in the working chamber 111 and discharge the water vapor in the air from the dishwasher 100.

[0081] It should be noted that the plurality of fans 120 may be disposed inside or outside the dishwasher 100. In an embodiment, one fan 120 is disposed adjacent to the heating device 170 to blow the thermal energy generated by the heating device 170 to the working chamber 111, and one fan 120 is disposed in the air flue 112 to guide the air into the air flue 112, thereby working simultaneously to speed up the air circulation in the working chamber 111.

[0082] In some embodiments, when the humidity is less than or equal to 50%, the first predefined time is about 170 minutes and the second predefined time is about 10 minutes; when the humidity is greater than 50% and less than or equal to 60%, the first predefined time is about 140 minutes, and the second predefined time is about 10 minutes; when the humidity is greater than 60% and less than or equal to 70%, the first predefined time is about 110 minutes, and the second predefined time is about 10 minutes; when the humidity is greater than 70% and less than or equal to 80%, the first predefined time is about 80 minutes, and the second predefined time is about 10 minutes; when the humidity is greater than 80% and less than or equal to 85%, the first predefined time is about 40 minutes, and the second predefined time is about 20 minutes; and when the humidity is greater than 85%, the first predefined time is about 10 minutes, and the second predefined time is about 20 minutes.

[0083] As such, the fan 120 may be controlled to run according to the humidity.

[0084] Specifically, when the humidity is less than or equal to 50%, indicating that the humidity is very small, the water vapor in the dishwasher 100 may not easily be condensed into water droplets, so the fan 120 is controlled to run for about 10 minutes after stopping running for about 170 minutes; when the humidity is greater than 50% and less than or equal to 60%, indicating that the humidity is smaller, so the fan 120 is controlled to run for about 10 minutes after stopping running for about 140 minutes; when the humidity is greater than 60% and less than or equal to 70%, indicating that the humidity is slightly higher, so the fan 120 is controlled to run for about 10 minutes after stopping running for about 110 minutes; when the humidity is greater than 70% and less than or equal to 80%, indicating that the humidity is higher, so the fan 120 is controlled to run for about 10 minutes after stopping running for about 80 minutes; when the humidity is greater than 80% and less than or equal to 85%, indicating that the humidity is very high, the water vapor in the dishwasher 100 may easily be condensed into water droplets, so the fan 120 is controlled to run for about 20 minutes after stopping running for about 40 minutes; when the humidity is greater than 85%, indicating that the humidity is extremely high, the water vapor in the dishwasher 100 has been substantially condensed into water droplets, so the fan 120 is controlled to run for about 20 minutes after stopping running for about 10 minutes.

[0085] In some embodiments, the third predefined time is the same as the first predefined time, and the fourth predefined time is the same as the second predefined time, that is, when the humidity is less than or equal to 50%, the third predefined time is about 170 minutes and the fourth predefined time is about 10 minutes; when the humidity is greater than 50% and less than or equal to 60%, the third predefined time is about 140 minutes, and the fourth predefined time is about 10 minutes; when the humidity is greater than 60% and less than or equal to 70%, the third predefined time is about 110 minutes, and the fourth predefined time is about 10 minutes; when the humidity is greater than 70% and less than or equal to 80%, the third predefined time is about 80 minutes, and the fourth predefined time is about 10 minutes; when the humidity is greater than 80% and less than or equal to 85%, the third predefined time is about 40 minutes, and the fourth predefined time is about 20 minutes; and when the humidity is greater than 85%, the third predefined time is about 10 minutes, and the fourth predefined time is about 20 minutes.

[0086] In some embodiments, when the humidity less than or equal to 55%, the third predefined time is about 170 minutes, and the fourth predefined time is about 10 minutes; when the humidity is greater than 55% and less than or equal to 70%, the third predefined time is about 110 minutes, and the fourth predefined time is about 20 minutes; when the humidity is greater than 70% and less than or equal to 85%, the third predefined time is about 60 minutes, and the fourth predefined time is about 20 minutes; and when the humidity is greater than 85%, the third predefined time is about 10 minutes, and the fourth predefined time is about 20 minutes.

[0087] As such, the fan 120 may be controlled to run according to the humidity.

[0088] Specifically, when the humidity is less than or equal to 55%, indicating that the humidity is very small, the water vapor in the dishwasher 100 may not easily be condensed into water droplets, so the fan 120 and the heating device 170 are controlled to run for about 10 minutes after stopping running for about 170 minutes; when the humidity is greater than 55% and less than or equal to 70%, indicating that the humidity is slightly higher, so the fan 120 and the heating device 170 are controlled to run for about 20 minutes after stopping running for about 110 minutes; when the humidity is greater than 70% and less than or equal to 85%, indicating that the humidity is higher, so the fan 120 and the heating device 170 are controlled to run for about 20 minutes after stopping running for about 60 minutes; when the humidity is greater than 85%, indicating that the humidity is extremely high, the water vapor in the dishwasher 100 has been substantially condensed into water droplets, so the fan 120 and the heating device 170 are controlled to run for about 20 minutes after stopping running for about 10 minutes.

[0089] With reference to Fig. 7, in some embodiments, the step S154 includes steps of:

S1542: determining whether the humidity is greater than a humidity threshold when no dish-brightening agent is fed by the feeding device 180;

S1544: controlling the fan 120 and the heating device 170 to run for the fourth predefined time after stopping running for the third predefined time according to the humidity after the dishwasher 100 finishes washing when the humidity is greater than the humidity threshold; and

S1546: controlling the fan 120 to run for the fourth predefined time after stopping running for the third predefined time and controlling the heating device 170 to stop running according to the humidity after the dishwasher 100 finishes washing when the humidity is less than or equal to the humidity threshold.



[0090] Again, with reference to Fig. 2, in some embodiments, the processor 150 is configured to:

determine whether the humidity is greater than a humidity threshold when no dish-brightening agent is fed by the feeding device 180;

control the fan 120 and the heating device 170 to run for the fourth predefined time after stopping running for the third predefined time according to the humidity after the dishwasher 100 finishes washing when the humidity is greater than the humidity threshold; and

control the fan 120 to run for the fourth predefined time after stopping running for the third predefined time and control the heating device 170 to stop running according to the humidity after the dishwasher 100 finishes washing when the humidity is less than or equal to the humidity threshold.



[0091] That is to say, the steps S1542, S1544 and S1546 may be implemented by the processor 150.

[0092] As such, the heating device 170 may be controlled to stop working when the humidity is less than or equal to the humidity threshold to reduce the power consumption of the dishwasher 100.

[0093] Specifically, when no dish-brightening agent is fed by the feeding device 180, the water marks attached to the dishes may be evaporated to form the water vapor through the working of the heating device 170, thereby using the fan 120 discharge the water vapor to prevent bacteria from breeding. When the humidity is greater than the humidity threshold, the humidity in the working chamber 111 is larger, and the fan 120 and the heating device 170 may be controlled to simultaneously run for the fourth predefined time after stopping running for the third predefined time according to the humidity; when the humidity is less than or equal to the humidity threshold, the humidity in the working chamber 111 is smaller, and the fan 120 may be controlled to run for the fourth predefined time after stopping running for the third predefined time and the heating device 170 may be controlled to stop working according to the humidity, thereby reducing the power consumption of the dishwasher 100.

[0094] It is to be understood that the humidity threshold may be preset in the dishwasher 100 or determined by a user input, e.g., the humidity threshold may be 60%, 70%, or 80%, which is not specifically limited herein.

[0095] With reference to Fig. 8, the dishwasher 100 of the embodiment of the present disclosure includes a housing 110, a fan 120, a humidity detection unit 140, a heating device 170, a feeding device 180, one or more processors 150, a memory 160, and one or more programs. Among them, the one or more programs are stored in the memory 160, and configured to be executed by the one or more processors 150, and the programs are configured to execute instructions of the control method of any one of above embodiments.

[0096] For example, the programs may be configured to execute instructions of the control method below:

S152: controlling the humidity detection unit 140 to detect a humidity after the dishwasher 100 finishes washing;

S153: controlling the fan 120 to run for a second predefined time after stopping running for a first predefined time according to the humidity after the dishwasher 100 finishes washing when the dish-brightening agent is fed by the feeding device 180, wherein the humidity is negatively correlated to the first predefined time, and the humidity is positively correlated to the second predefined time; and

S154: controlling the fan 120 and the heating device 170 to run for a fourth predefined time after stopping running for a third predefined time according to the humidity after the dishwasher 100 finishes washing when no dish-brightening agent is fed by the feeding device 180, wherein the humidity is negatively correlated to the third predefined time, and the humidity is positively correlated to the fourth predefined time.



[0097] With reference to Fig. 9, a computer-readable storage medium 200 of the embodiment of the present disclosure includes a computer program for use in conjunction with the dishwasher 100, and the computer program is executable by the processor 150 to complete the control method of any one of above embodiments of the present disclosure.

[0098] For example, the computer program may be executed by the processor 150 to complete the following control methods:

S151: determining whether a dish-brightening agent is fed by the feeding device 180;

S152: controlling the humidity detection unit 140 to detect a humidity after the dishwasher 100 finishes washing;

S153: controlling the fan 120 to run for a second predefined time after stopping running for a first predefined time according to the humidity after the dishwasher 100 finishes washing when the dish-brightening agent is fed by the feeding device 180, wherein the humidity is negatively correlated to the first predefined time, and the humidity is positively correlated to the second predefined time; and

S154: controlling the fan 120 and the heating device 170 to run for a fourth predefined time after stopping running for a third predefined time according to the humidity after the dishwasher 100 finishes washing when no dish-brightening agent is fed by the feeding device 180, wherein the humidity is negatively correlated to the third predefined time, and the humidity is positively correlated to the fourth predefined time.



[0099] It should be noted that the computer readable storage medium 200 may be a storage medium built in the dishwasher 100, or a storage medium that may be plugged and inserted in the dishwasher 100.
