[0037] The present application provides a refrigerator control method, device, equipment and storage medium, which are described in detail below.

[0038] See also Figure 1 , Figure 1 1 is a schematic diagram of a refrigerator control system provided in an embodiment of the present application, and the refrigerator control system may include a refrigerator 100. Figure 1 The refrigerator 100 in the embodiment can obtain the relevant control logic stored in the refrigerator 100 to execute the refrigerator control method in the present application.

[0039] In the embodiment of the present application, the refrigerator 100 includes but is not limited to a double-door refrigerator, a single-door refrigerator, a freezer, etc.

[0040] It should be noted that Figure 1 The scene diagram of the refrigerator control system shown is only an example. The refrigerator control system and scene described in the embodiment of the present application are intended to more clearly illustrate the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application. A person of ordinary skill in the art can know that with the evolution of the refrigerator control system and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0041] like Figure 2 As shown, Figure 2The flowchart of a refrigerator control method in an embodiment of the present application is a schematic diagram. The method is applied to a refrigeration device. The refrigeration device includes a damper and a thermoelectric module. The thermoelectric module is attached to the damper. The thermoelectric module is used to heat the damper. The method specifically includes the following steps 201 to 202:

[0042] 201. Get the current air door temperature.

[0043] In the embodiment of the present application, the damper is usually arranged in the air duct to control the flow of cold air entering the refrigeration compartment. Among them, the scheme for obtaining the current damper temperature can be achieved by setting a temperature sensor on the damper, and collecting the temperature of the damper through the temperature sensor. Among them, the specific setting position of the temperature sensor can be set according to actual conditions, and the embodiment of the present application is not limited to it. For example: installing temperature sensors on the damper surface and the surrounding area. Install 5 temperature sensors, respectively located at the four corners and a center position of the damper surface. At this time, 5 temperatures can be collected. Afterwards, the 5 temperatures are averaged to obtain the average temperature, and the average temperature is used as the current damper temperature.

[0044] 202. According to the current damper temperature, adjust the current of the thermoelectric module.

[0045] In the embodiment of the present application, the damper usually freezes at 0 degrees. Therefore, if the current damper temperature is lower, or closer to 0 degrees, the electric heating module can be powered on. In this way, the thermoelectric module will generate heat due to power on, thereby heating the damper. Among them, if the current damper temperature is lower, the power-on current will be greater. In addition, in the embodiment of the present application, the thermoelectric module can be a Peltier element, and its size can be matched with the specific damper size.

[0046] The method for preventing the damper from freezing provided by the present application can obtain the current damper temperature and determine whether the damper is frozen according to the current damper temperature. Then, the damper can be heated according to the specific damper temperature using the heat generated by the power supply of the thermoelectric module to prevent the damper from freezing.

[0047] In order to better implement the embodiment of the present application, in one embodiment of the present application, adjusting the current of the thermoelectric module according to the current damper temperature includes:

[0048] Obtaining a first target temperature threshold; and adjusting a current of the thermoelectric module according to the current damper temperature and the first target temperature threshold.

[0049] In specific situations, the damper may not only freeze, but also frost. The temperature at which the damper frosts will be higher than 0 degrees. Therefore, in the embodiment of the present application, the first target temperature threshold may be the critical point temperature of frost. For example, any temperature value within the range of 0 to 5 degrees may be used as the first target temperature threshold, which may be set specifically according to actual conditions. If the current damper temperature is closer to the first temperature threshold, the current of the thermoelectric module may be increased, otherwise the current may be reduced.

[0050] In order to better implement the embodiment of the present application, in one embodiment of the present application, adjusting the current of the thermoelectric module according to the current damper temperature and the first target temperature threshold includes:

[0051] If the current damper temperature is less than or equal to the first target temperature threshold, the target current value is determined according to the difference between the current damper temperature and the first target temperature threshold; and the current of the thermoelectric module is adjusted according to the target current value.

[0052] The above embodiment provides a first target temperature threshold and a solution for current regulation. However, in order to accurately regulate the specific adjustment, the embodiment of the present application also provides a solution. Specifically, as shown in formula (1):

[0053] First target temperature threshold - current air door temperature = difference... (1)

[0054] According to formula (1), if the first target temperature threshold is 3 degrees and the current damper temperature is 2 degrees, the difference is 1 degree. If the difference is positive, it proves that the damper temperature is already lower than the temperature threshold. At this time, it is necessary to further increase the current so that the damper quickly heats up to a temperature that will not freeze or frost. If the first target temperature threshold is 3 degrees and the current damper temperature is 4 degrees, the difference is -1 degree. At this time, if the difference is negative, it proves that the current damper temperature is higher than the first temperature threshold and there is no risk of freezing. However, it should be noted that if the difference is negative, but the absolute value of the difference is smaller, it proves that although the damper temperature has not yet reached the state of freezing or frosting, it is close to the state of freezing or frosting. At this time, in order to avoid freezing or frosting, the current can be increased to a certain extent. The increased current can be less than the amount of current increased when the difference is positive.

[0055] In order to better implement the embodiment of the present application, in one embodiment of the present application, after adjusting the current of the thermoelectric module according to the target current value, the method includes:

[0056] Determine the temperature change rate of the damper; if the temperature change rate is less than or equal to the rate change threshold, increase the current of the thermoelectric module according to the first current increment.

[0057] The above embodiment provides a solution to increase the current to prevent the damper from freezing or frosting. However, in a specific process, after the current is increased, the temperature of the damper may not increase or increase slowly due to some unknown reasons. At this time, the damper still has the risk of freezing. At this time, it is necessary to combine the temperature change rate.

[0058] Specifically, after increasing the current, it is necessary to detect the temperature change rate of the damper. For example, within 1 minute of increasing the current, detect the temperature change. If the temperature change rate is less than the rate change threshold, it proves that the damper temperature rise is not obvious or has not risen, and the current needs to be further increased.

[0059] For example, if the temperature change rate is less than the rate change threshold, the controller increases the current (assuming the increment is 0.5A). If the temperature change rate remains unchanged, the controller can increase the current by another 0.2A. After that, assuming the temperature rise is still slow, the controller may increase the current by another 0.1A. Finally, the controller adjusts the current of the thermoelectric module to 0.8A and starts heating the damper surface.

[0060] In order to better implement the embodiment of the present application, in one embodiment of the present application, adjusting the current of the thermoelectric module according to the current damper temperature and the first target temperature threshold includes:

[0061] If the current damper temperature is greater than the first target temperature threshold, the current flowing through the thermoelectric module is reduced.

[0062] The above embodiment provides a first target temperature threshold value which can be a critical temperature for frosting. However, in some cases, if the damper temperature is higher than a certain level and the compressor power is reduced, the damper will not continue to lower the temperature. Therefore, the compressor will no longer deliver air at a lower temperature. At this time, there is no need to heat the damper, so the current can be gradually reduced. Therefore, in the embodiment of the present application, the first target temperature threshold value can also be a temperature threshold value for determining the reduction of current. For example: any temperature above 5 degrees is not limited by the embodiment of the present application.

[0063] In order to better implement the embodiment of the present application, in one embodiment of the present application, if the current damper temperature is greater than the first target temperature threshold, after reducing the current of the thermoelectric module, the method further includes:

[0064] If the current damper temperature is greater than the second target temperature threshold, power to the thermoelectric module is stopped.

[0065] The above embodiment provides a solution for reducing the current. However, if the temperature of the damper continues to rise until it exceeds the second target temperature threshold, when the damper has a sufficiently high temperature, it is no longer necessary to heat it, and the power supply can be stopped. The second target temperature threshold is greater than the first target temperature threshold, for example, the second target temperature threshold can be 8 degrees, 9 degrees, 10 degrees, etc.

[0066] In order to better implement the embodiments of the present application, in one embodiment of the present application, the thermoelectric module includes an insulating layer, a first metal layer and a second metal layer;

[0067] The first metal layer is arranged between the second metal layer and the insulating layer, the second metal layer is arranged in contact with the damper, the thermoelectric module is arranged in the first metal layer or the thermoelectric module is arranged in the second metal layer, and the thermal conductivity of the first metal layer is less than the thermal conductivity of the second metal layer.

[0068] The above embodiment provides a solution in which a thermoelectric module is directly mounted on the damper. However, the embodiment of the present application also provides a thermoelectric module with other structures.

[0069] Among them, since the thermal module needs to be powered, an insulating layer can be provided, and the material of the insulating layer can be rubber, polyurethane foam, etc., which is not limited in the embodiment of the present application. At the same time, the material of the first metal layer can be aluminum alloy with medium thermal conductivity, and the thickness can be 5 mm; the second metal layer can be copper with high thermal conductivity, and the thickness can be 2 mm.
