Description

Technical Field

[0001] The present application relates to the technical field of washer-dryer control, and in particular to a control method, device, electronic equipment, washer-dryer, and storage medium. Background Art

[0002] When a washer-dryer is installed in a built-in configuration, for example, within a cabinet or similar enclosed structure, air flow is poor. During the drying process, the washer-dryer emits heat, heating the surrounding air and forming hot air.

In this case, the ambient temperature obtained before the drying cycle runs significantly differs from the actual ambient temperature. Using the pre-drying temperature as the ambient temperature for determining the drying status of clothing will affect the accuracy of the dryness determination, potentially leading to over-drying or incomplete drying of clothing.

[0048] Example 1

[0049] The embodiment of the present application provides a control method, Figure 3 A schematic diagram of the implementation flow of a control method provided in an embodiment of the present application is shown in FIG. Figure 3 Shown, including:

[0050] Step S101: During the drying process of the washer-dryer, temperature information of the environment in which the washer-dryer is located is obtained.

[0051] In an embodiment of the present application, the washer-dryer may be a washing machine having both a washing and drying function. The electronic device may receive user operations to control the washer-dryer to perform drying. In some embodiments, after the washer-dryer completes washing, the drying process may be automatically performed.

[0052] In an embodiment of the present application, the electronic device can be connected to a temperature sensor for communication, and obtain temperature information of the environment in which the washer-dryer is located through the temperature sensor.

[0053] In the embodiment of the present application, the temperature sensor is arranged at the rear of the top cover of the washer-dryer. The temperature of the environment can be considered as the temperature outside the washer-dryer body.

[0054] Step S102: determining the location of the washer-dryer based on the temperature information.

[0055] In the embodiment of the present application, step S102 can be implemented by the following steps:

[0056] Step S1021: determining the temperature change rate based on the temperature information.

[0057] In the embodiment of the present application, during drying, the heat of the air duct components is radiated to the machine body, which then exchanges heat with the surrounding air. Due to the different placement of the washer-dryer by the user and the different spatial shielding, the heat exchange effect between the washer-dryer and the surrounding air varies. For example, if the washer-dryer is installed in a relatively open area, the heat exchange with the air is faster, and the temperature change of the surrounding air is smaller. If the washer-dryer is installed in a relatively closed cabinet, it is more difficult to exchange heat with the surrounding air, and the temperature of the surrounding air rises faster. Therefore, the temperature change rate can be determined by the temperature information of the temperature sensor installed at the rear of the top cover. The temperature change rate can be calculated by ΔT / Δt.

[0058] Step S1022: Determine the location of the washer-dryer based on the temperature change rate.

[0059] In the embodiment of the present application, step S1022 can be implemented by the following steps:

[0060] When the temperature change rate is greater than or equal to the temperature change rate threshold, the position of the washer-dryer is determined to be the first position; when the temperature change rate is less than the temperature change threshold, the position of the washer-dryer is determined to be the second position, wherein the degree of closure of the first position is greater than the degree of closure of the second position.

[0061] For example, the first location may be inside a closed cabinet, and the second location may be on a relatively open balcony.

[0062] Step S103: determining a return air temperature threshold corresponding to the location of the washer-dryer based on the location of the washer-dryer.

[0063] In the embodiments of the present application, the return air temperature during clothing drying is not only related to the quality of the clothing but also affected by the ambient temperature. The return air temperature during clothing drying varies at different ambient temperatures. Generally, the higher the ambient temperature, the higher the return air temperature during clothing drying.

[0064] In an embodiment of the present application, when the position of the washer-dryer is the first position, the return air temperature threshold corresponding to the position of the washer-dryer is determined to be the first return air temperature threshold; when the position of the washer-dryer is the second position, the return air temperature threshold corresponding to the position of the washer-dryer is determined to be the second return air temperature threshold, wherein the first return air temperature threshold is greater than the second return air temperature threshold.

[0065] In step S104, when the return air temperature of the washer-dryer is greater than or equal to the return air temperature threshold corresponding to the position, it is determined whether the clothes in the washer-dryer are dried based on the return air temperature of the return air outlet of the washer-dryer and the inlet air temperature of the air inlet of the washer-dryer at the same time.

[0066] In the embodiment of the present application, step S104 can be implemented by the following steps:

[0067] Step S1041 : determining a temperature difference based on the return air temperature of the return air outlet of the washer-dryer and the inlet air temperature of the inlet of the washer-dryer 5 at the same time.

[0068] In an embodiment of the present application, the temperature difference between the return air temperature and the inlet air temperature of the washer-dryer can be determined, and the temperature difference can be expressed as: Tb-Ta, where the return air temperature is Tb and the inlet air temperature is Ta.

[0069] Step S1042: determining a temperature difference change rate of the temperature difference per unit time based on the temperature difference.

[0070] In the embodiment of the present application, the unit time can be configured, and for example, can be 1 second. The temperature difference change rate can be calculated by the following formula: Δ(Tb-Ta) / Δt.

[0071] In the embodiment of the present application, the temperature difference change rate can be calculated through a coordinate system, where Δ(Tb-Ta) is the difference between any two points on the time / temperature curve with time t as the horizontal axis and Tb-Ta as the vertical axis, and Δt is the time difference corresponding to the two points, that is, the temperature difference change rate is the slope of the return air temperature and inlet air temperature difference / time curve at any point.

[0072] Step S1043: Determine whether the clothes in the washing and drying machine are dried based on the temperature difference change rate.

[0073] In the embodiment of the present application, the temperature difference change rate is compared with the temperature difference change rate threshold to obtain a comparison result; based on the comparison result, it is determined whether the clothes in the washing and drying machine are dried, wherein the comparison result indicates that the temperature difference change rate is greater than or equal to the temperature difference change rate threshold.

[0074] When the comparison result indicates that the temperature difference change rate is less than or equal to the temperature difference change threshold, it is determined that the clothes in the washer-dryer are not dried.

[0075] Step S105: When the clothes in the washing and drying machine are drying, control the washing and drying machine to stop drying.

[0076] In an embodiment of the present application, if the clothes in the drying machine are not dried, the return air temperature of the return air outlet of the washing and drying machine and the inlet air temperature of the air inlet of the washing and drying machine at the same time continue to be obtained, and the judgment is continued.

[0077] The present application provides a control method, which obtains temperature information of the environment in which the washer-dryer is located during the drying process of the washer-dryer; determines the position of the washer-dryer based on the temperature information; determines a return air temperature threshold corresponding to the position of the washer-dryer based on the position of the washer-dryer; and, when the return air temperature of the washer-dryer is greater than or equal to the return air temperature threshold corresponding to the position, determines whether the clothes in the washer-dryer are dried based on the return air temperature of the return air outlet of the washer-dryer and the inlet air temperature of the air inlet of the washer-dryer at the same time; and, when the clothes in the washer-dryer are dried, controls the washer-dryer to stop drying, thereby improving the accuracy of the drying judgment and avoiding over-drying or incomplete drying.

[0078] Example 2:

[0079] Based on the above embodiments, the present application further provides a control method, the specific implementation of which is as follows:

[0080] When the drying program is running, the temperature sensor obtains temperature data T from the environment and transmits the value to the controller of the washing machine. During drying, the heat of the air duct components is radiated to the machine body, and the machine body then exchanges heat with the surrounding air. Due to the different placement of the washer-dryer by the user and the different spatial obstructions, the heat exchange effect between the washer-dryer and the surrounding air is different. For example, if the washer-dryer is installed in a more open area, the heat exchange with the air is faster and the temperature change of the surrounding air is smaller; if the washer-dryer is installed in a more closed cabinet, it is more difficult to exchange heat with the surrounding air, and the temperature of the surrounding air rises faster. Therefore, the temperature change rate ΔT / Δt (the ratio of time t as the horizontal axis and ambient temperature T as the vertical axis within Δt = 5s) can be calculated by analyzing the temperature information of the temperature sensor installed at the back of the top cover to determine whether the washer-dryer is installed on a more open balcony or in a more closed cabinet.

[0081] The return air temperature Tb when drying clothes is not only related to the quality of the clothes, but also affected by the ambient temperature T. The return air temperature when drying clothes is different under different ambient temperatures. Generally speaking, the higher the ambient temperature, the higher the return air temperature when drying clothes. Therefore, for different ambient temperatures, the dryness judgment conditions are different. When the washing and drying machine dries clothes, the dryness of the clothes is related to the return air temperature. The rate of change per unit time δ of the difference between the return air temperature Tb and the inlet air temperature Ta can be used to judge whether the clothes are dry, that is, Δ(Tb-Ta) / Δt (Δ(Tb-Ta) is the difference between any two points of the time / temperature curve with time t as the horizontal axis and Tb-Ta as the vertical axis, Δt is the time difference corresponding to the two points, that is, δ is the slope of the return air temperature and inlet air temperature difference / time curve at any point). When its change rate reaches a certain set value δ, it can be determined that the clothes are dried.

[0082] When the user uses the drying program, a temperature sensor installed at the rear of the top cover obtains temperature data T from the environment, and the controller calculates the rate of change of the ambient temperature during drying, ε, that is, ΔT / Δt. If the calculated ε<ε0 (ε0 is a preset value), it is determined that the washer-dryer is installed in an open area with good ventilation and heat dissipation conditions. Otherwise, it is determined that the washer-dryer is installed in a closed cabinet with poor ventilation and heat dissipation conditions. Due to different ambient temperatures, using the same temperature to judge drying can easily result in the clothes actually being dried. Therefore, it is necessary to compensate the preset return air temperature Treturn by Δb in the closed cabinet installed with poor ventilation and heat dissipation conditions, that is, Treturn=Treturn+Δb. During the drying process, the value Tb obtained by the temperature sensor installed at the return air is compared with Treturn. If Tb≥Treturn, the rate of change δ of the difference between the return air temperature Tb and the outlet air temperature Ta, that is, δ=Δ(Tb-Ta) / Δt, is compared with the preset value δ0. If δ≥δ0, it is determined that the clothes are dried and the drying program ends. Otherwise, the above steps are repeated.

[0083] A control method provided in the implementation of this application enables the washer-dryer to self-sense its installation location by setting a temperature sensor for measuring the ambient temperature at the rear of the top cover, and automatically adjust the drying temperature according to the changes in the ambient temperature during the drying process, so that the clothes will not be over-dried or incompletely dried, thereby improving user satisfaction.
