Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a method and device for controlling refrigeration equipment, refrigeration equipment, and a storage medium. Background Art

[0002] As people's demand for food freezing and preservation gradually increases, refrigerators, freezers and other refrigeration appliances are used more and more widely. Due to the user's usage habits and the different environments in which refrigeration appliances are located, frost will appear on refrigeration appliances when they are working. Excessive frost may even affect the operation of the fan, resulting in poor refrigeration effect and affecting food freezing and preservation.

[0003] The related technology discloses a defrost control method, including: obtaining the working state of the fan; if the fan is in a fault state, entering fault defrost, starting the heating module, and turning off the heating module until the temperature detected by the defrost sensor reaches 20°C.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] If the fan is in a refrigeration device with an extremely low temperature, there may be a situation where there is no large amount of frost on the fan, but the fan is faulty. In this case, the relevant technology determines that the fan is in a faulty state and enters the fault defrosting. In fact, there is no large amount of frost on the fan, and it does not require an excessively high temperature for defrosting.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0008] The embodiments of the present disclosure provide a method and apparatus for controlling a refrigeration device, a refrigeration device, and a storage medium to reduce the possibility of fan failure under extremely low temperature conditions.

[0009] In some embodiments, the method includes: detecting a target temperature; when the target temperature is less than or equal to a reference temperature, detecting a defrost temperature to obtain the temperature of a control panel; when the temperature of the control panel is less than or equal to a second temperature threshold, turning on a heating device to heat the control panel.

[0010] When the set temperature is less than or equal to the target temperature, it is determined that the fan is in an extremely low temperature environment. When the temperature of the control board is lower than or equal to the second temperature threshold, the heating device is turned on to increase the temperature of the control board. By the operation of the heating device, the temperature of the control board built in the fan is maintained within the normal temperature range. The situation where the fan cannot operate normally due to the too low temperature of the control board built in the fan is reduced. Thus, the situation where the fan fails under extremely low temperature conditions is reduced.

[0011] In some embodiments, turning on the heating device to heat the control board includes: when T1 < T ≤ T2, turning on the heating device and adjusting the operating power of the heating device to the second operating power; or, when T ≤ T1, turning on the heating device and adjusting the operating power of the heating device to the first operating power; where T is the temperature of the control board, T1 is the first temperature threshold, T2 is the second temperature threshold, and the first operating power is greater than the second operating power.

[0012] When the temperature of the control board is lower than or equal to the second temperature threshold, the control board cannot work properly due to the too low temperature. Therefore, the heating device is turned on to raise the temperature of the control board. According to the different current temperatures of the control board, the operating power of the heating device is also different. The temperature of the control board is raised to the normal operating temperature range, thereby reducing the situation where the fan cannot operate normally due to the too low temperature of the control board built in the fan.

[0013] In some embodiments, the method further includes: when T > T2, turning off the heating device.

[0014] When the temperature of the control board is greater than the second temperature threshold, the current temperature of the control board is within the normal operating temperature range. After the control board can work normally, the heating device is turned off. Thus, the energy consumption is reduced and the energy is saved.

[0015] In some embodiments, before detecting the defrosting temperature and obtaining the temperature of the control board, it further includes: when the target temperature is less than or equal to the reference temperature, obtaining the current defrosting situation of the refrigeration device; when the refrigeration device is defrosting, turning off the heating device; or, when the refrigeration device is not defrosting, obtaining the current operating situation of the compressor; when the compressor is operating, turning on the heating device and adjusting the operating power of the heating device to the first operating power; or, when the compressor is stopped, detecting the defrosting temperature.

[0016] When the refrigeration device is defrosting, the whole refrigeration device is in a temperature rising process. The temperature of the control board is within the normal operating range, and the heating device is turned off, thereby reducing the waste of resources. Since the operation of the compressor of the refrigeration device generates cold, the temperature of the control board is reduced. The heating device is turned on to raise the temperature of the control board. Thus, the temperature of the control board is maintained within the normal operating temperature range.

[0017] In some embodiments, the method further comprises: when the target temperature is greater than the reference temperature, turning off the heating device.

[0018] When the target temperature is greater than the reference temperature, the overall temperature of the refrigeration equipment is within the normal operating temperature range of the control panel. Turning off the heating device reduces energy loss and saves energy.

[0019] In some embodiments, the apparatus comprises: a processor and a memory storing program instructions, wherein the processor is configured to execute the method for controlling refrigeration equipment when running the program instructions.

[0020] In some embodiments, the refrigeration equipment includes a compressor and a fan, and a control panel is arranged inside the fan, wherein the fan includes: a heating device, which is arranged at the bottom of the fan, below the control panel, and is started in a controlled manner to heat the control panel.

[0021] In some embodiments, the distance between the heating device and the control panel is [1.5 mm, 2.5 mm].

[0022] In some embodiments, the refrigeration equipment further includes: the device for controlling the refrigeration equipment.

[0023] In some embodiments, the storage medium stores program instructions, wherein the program instructions, when run, execute the method for controlling refrigeration equipment.

[0037] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0038] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0039] The embodiment of the present disclosure provides a refrigeration device, including a computer board, a compressor, a fan, and a temperature sensor. The computer board is provided with a processor. A control board is provided inside the fan. The fan includes a heating device. The temperature sensor is provided around the fan. Figure 1 As shown, the heating device 01 is arranged at the bottom of the fan 02 and below the control panel, and is controlled to start and heat the control panel. The compressor, temperature sensor, processor and heating device constitute a heating control system. Figure 2 The heating control system includes a temperature sensor 12, a compressor 13, a processor 14 and a heating device 15. The temperature sensor 12 is used to detect the defrosting temperature and send the defrosting temperature to the processor 14. The processor 14 can obtain the current defrosting status of the refrigeration equipment and the operation status of the compressor 13. The processor 14 can receive the information sent by the temperature sensor 12, receive the information input by humans, and analyze and process the received and obtained information. According to the analysis results, an operation instruction is sent to the heating device 15. The heating device 15 receives the instruction of the processor 14, and starts and operates according to the instruction.

[0040] Optionally, the refrigeration equipment includes a refrigerator or a freezer.

[0041] Optionally, the distance between the heating device and the control board is [1.5mm, 2.5mm].

[0042] There is a certain distance between the heating device and the control board to reduce the possibility of components in the control board being burned out. The distance between the heating device and the control board is not too far, and when the heating device is working, the time for heat to be transferred to the control board is short. This reduces heat loss and thus reduces energy consumption.

[0043] Specifically, the distance between the heating device and the control board includes: 1.5 mm, 2 mm or 2.5 mm.

[0044] When the heating device is working, the distance between the heating device and the control panel shortens the time for heat to be transferred to the control panel. The loss during heat transfer is reduced, thereby reducing energy consumption.

[0045] Optionally, the wiring shape of the heating device includes: fork shape, mosquito coil shape, meander shape or Z shape.

[0046] The heating device is evenly distributed at the bottom of the fan, so that the control panel is evenly heated.

[0047] Optionally, the heating device includes a heating wire, a heating film and a silicone heating wire.

[0048] The heating device has good thermal conductivity, which is conducive to quickly heating the control board.

[0049] Combination Figure 3 As shown, the embodiment of the present disclosure provides a method for controlling a refrigeration device, comprising:

[0050] S301, the processor detects the target temperature.

[0051] In S302, when the target temperature is less than or equal to the reference temperature, the processor detects the defrosting temperature and obtains the temperature of the control board.

[0052] In S303, when the temperature of the control board is lower than or equal to the second temperature threshold, the processor turns on the heating device to heat the control board.

[0053] When the set temperature is less than or equal to the target temperature by using the method for controlling a refrigeration device provided by the embodiment of the present disclosure, it is determined that the fan is in an extremely low temperature environment. When the temperature of the control board is lower than or equal to the second temperature threshold, the heating device is turned on to increase the temperature of the control board. By the operation of the heating device, the temperature of the control board built in the fan is maintained within the normal temperature range. The situation that the fan cannot operate normally due to the too low temperature of the control board built in the fan is reduced. Thus, the situation that the fan fails under extremely low temperature conditions is reduced.

[0054] The target temperature is the temperature set by the user when using the refrigeration device. The reference temperature is the lowest temperature within the normal operating temperature range of the control board, which is set to -40°C.

[0055] Optionally, turning on the heating device to heat the control board includes: when T1 < T ≤ T2, turning on the heating device and adjusting the operating power of the heating device to the second operating power. Or, when T ≤ T1, turning on the heating device and adjusting the operating power of the heating device to the first operating power. Wherein, T is the temperature of the control board, T1 is the first temperature threshold, T2 is the second temperature threshold, and the first operating power is greater than the second operating power. In this way, when the temperature of the control board is lower than or equal to the second temperature threshold, the control board cannot work normally due to the too low temperature. Therefore, the heating device is turned on to raise the temperature of the control board. According to the different current temperatures of the control board, the operating power of the heating device is also different. This enables the temperature of the control board to rise to the normal operating temperature range, and can better reduce the situation that the fan cannot operate normally due to the too low temperature of the control board built in the fan.

[0056] The value range of the first temperature threshold is [-41°C, -39°C]. The value range of the first operating power is [1.8W, 2.1W]. The value range of the second temperature threshold is [-31°C, -29°C]. The value range of the second operating power is [0.9W, 1.2W].

[0057] Specifically, the first temperature threshold includes: -41°C, -40°C or -39°C.

[0058] Specifically, the second temperature threshold includes: -31°C, -30°C or -29°C.

[0059] Specifically, the first operating power includes: 1.8W, 1.9W, 2.0W or 2.1W.

[0060] Specifically, the second operating power includes: 0.9W, 1.0W, 1.1W or 1.2W.

[0061] In this way, considering that there is a certain distance between the heating device and the control board and the wiring area of ​​the heating device, and the control board contains a large number of components, the temperature of the control board is limited. The temperature of the control board cannot be too high and must reach the normal operating temperature range. The first operating power selection is [1.8W, 2.1W]. Reduce the situation of burning components on the control board and make the temperature of the control board within the normal operating temperature range. Considering that the fan is used to transmit the cold energy generated by the compressor during operation, the second power selection is [0.9W, 1.2W]. Run the heating device at a lower power to continuously heat the control board. Reduce the situation where the control board cannot work because the fan transmits cold energy and its own temperature is lower than the first temperature threshold.

[0062] Optionally, the method further includes turning off the heating device when T>T2. When the temperature of the control panel is greater than the second temperature threshold, the current temperature of the control panel is within the normal operating temperature range. In this way, the heating device is turned off after the control panel can work normally. This can better reduce energy consumption and save energy.

[0063] Optionally, before detecting the defrost temperature and obtaining the temperature of the control panel, the method further includes: when the target temperature is less than or equal to the reference temperature, obtaining the current defrost condition of the refrigeration equipment. When the refrigeration equipment is defrosting, turning off the heating device. Alternatively, when the refrigeration equipment is not defrosting, obtaining the current operating condition of the compressor. When the compressor is running, turning on the heating device and adjusting the operating power of the heating device to the first operating power. Alternatively, when the compressor is turned off, detecting the defrost temperature. In this way, when the refrigeration equipment is defrosting, the refrigeration equipment as a whole is in a heating process. When the temperature of the control panel is within the normal operating range, the heating device is turned off, thereby reducing resource waste. Since the operation of the compressor of the refrigeration equipment generates cold air, the temperature of the control panel is reduced. Turning on the heating device increases the temperature of the control panel. In this way, the temperature of the control panel can be better maintained within the normal operating temperature range.

[0064] Optionally, the method further comprises: when the target temperature is greater than the reference temperature, turning off the heating device. When the target temperature is greater than the reference temperature, the overall temperature of the refrigeration device is within the normal operating temperature range of the control panel. This can better reduce energy loss and extend the service life of the device.

[0065] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for controlling a refrigeration device, comprising:

[0066] S401, the processor detects the target temperature.

[0067] S402: When the target temperature is less than or equal to the reference temperature, the processor obtains the current defrosting status of the refrigeration equipment.

[0068] S403: When the refrigeration device is defrosting, the processor turns off the heating device.

[0069] S404: When the refrigeration equipment is not defrosted, the processor obtains the current operation status of the compressor.

[0070] S405: When the compressor is running, the processor turns on the heating device and adjusts the operating power of the heating device to a first operating power.

[0071] S406, the processor detects the defrost temperature when the compressor is turned off.

[0072] S407, the processor obtains the temperature of the control panel according to the defrosting temperature.

[0073] S408: When the temperature of the control board is lower than or equal to the second temperature threshold, the processor turns on the heating device to heat the control board.

[0074] By using the method for controlling refrigeration equipment provided by the embodiment of the present disclosure, when the set temperature is less than or equal to the target temperature, it is determined that the fan is in an extremely low temperature environment. If the refrigeration equipment is in the process of defrosting, the temperature of the control board is within the normal operating temperature range. Turn off the heating device to reduce energy consumption. When the compressor of the refrigeration equipment is running, the coldness generated by the compressor will affect the temperature of the control board. Turn on the heating device to heat the control board so that the temperature of the control board is within the normal operating temperature range. When the temperature of the control board is lower than or equal to the second temperature threshold, turn on the heating device to increase the temperature of the control board. The heating device is used to maintain the temperature of the built-in control board of the fan within the normal temperature range. Reduce the situation where the fan cannot operate normally because the temperature of the built-in control board of the fan is too low. Thereby reducing the situation where the fan fails under extremely low temperature conditions.

[0075] In an actual application scenario, when the user uses the refrigerator, the set temperature is -50℃. The processor detects that the target temperature is -50℃. Since the target temperature -50℃ is lower than the reference temperature -40℃, the processor obtains the current defrosting situation. Assume that the information obtained by the processor is that the current refrigeration device is not defrosting. The processor obtains the current operation status of the compressor. Assume that the information obtained by the processor is that the current compressor is running. The processor sends an opening instruction to the heating device, and the operating power is the first operating power. After receiving the instruction, the heating device starts to operate, and the operating power is adjusted to the first operating power. When it is detected that the refrigeration device is defrosting, the processor sends a closing instruction to the heating device to turn off the heating device. When it is detected that the refrigeration device is not defrosting and the compressor is turned off, the temperature sensor sends the temperature information to the processor. Assuming that the defrosting temperature is -33℃, the temperature of the control board is -33℃. The second temperature threshold is -30℃. The first temperature threshold is -40℃. The first operating power is 2W. The second operating power is 1W. Since the temperature of the control board is lower than the second temperature threshold and higher than the first temperature threshold, the processor sends an on instruction to the heating device, and the operating power is the second operating power. After receiving the instruction, the heating device starts and operates the heating device, and the operating power is adjusted to 1W.

[0076] Combination Figure 5 As shown, the embodiment of the present disclosure provides another method for controlling a refrigeration device, comprising:

[0077] S501, the processor detects the target temperature.

[0078] S502: When the target temperature is greater than the reference temperature, the processor turns off the heating device.

[0079] S503: When the target temperature is less than or equal to the reference temperature, the processor obtains the current defrosting status of the refrigeration equipment.

[0080] S504: When the refrigeration device is defrosting, the processor turns off the heating device.

[0081] S505: When the refrigeration device is not defrosted, the processor obtains the current operation status of the compressor.

[0082] S506: When the compressor is running, the processor turns on the heating device and adjusts the operating power of the heating device to a first operating power.

[0083] S507, the processor detects the defrosting temperature when the compressor is turned off.

[0084] S508: The processor obtains the temperature of the control panel according to the defrosting temperature.

[0085] S509: When the temperature of the control board is lower than or equal to the second temperature threshold, the processor turns on the heating device to heat the control board.

[0086] S510: When the temperature of the control board is higher than a second temperature threshold, the processor turns off the heating device.

[0087] According to the method for controlling a refrigeration device provided by the embodiment of the present disclosure, when the target temperature is greater than the reference temperature, the ambient temperature of the control panel is within the normal operating temperature range of the control panel. The heating device is turned off to reduce energy waste. If the refrigeration device is in the process of defrosting, the temperature of the control panel is within the normal operating temperature range. The heating device is turned off to reduce energy consumption. When the compressor of the refrigeration device is running, the coldness generated by the compressor will affect the temperature of the control panel. The heating device is turned on to heat the control panel so that the temperature of the control panel is within the normal operating temperature range. When the set temperature is less than or equal to the target temperature, it is determined that the fan is in an extremely low temperature environment. When the temperature of the control panel is lower than or equal to the second temperature threshold, the heating device is turned on to increase the temperature of the control panel. When the temperature of the control panel is higher than the second temperature threshold, the temperature of the control panel is within the normal operating temperature range. Therefore, the heating device is turned off to save energy. The temperature of the built-in control panel of the fan is maintained within the normal temperature range by the operation of the heating device. The situation where the fan cannot operate normally due to the low temperature of the built-in control panel of the fan is reduced. Thus, the situation where the fan fails under extremely low temperature conditions is reduced.

[0088] In another practical application scenario, when the user uses the refrigerator, the set temperature is -50℃. The processor detects that the target temperature is -50℃. Since the target temperature -50℃ is lower than the reference temperature -40℃, the processor obtains the current defrosting situation. Assume that the information obtained by the processor is that the current refrigeration equipment is not defrosting. The processor obtains the current operation status of the compressor. Assume that the information obtained by the processor is that the current compressor is running. The processor sends a start instruction to the heating device, and the operating power is the first operating power. After receiving the instruction, the heating device starts to run, and the operating power is adjusted to the first operating power. When the compressor is detected to be shut down, the temperature sensor sends the temperature information to the processor. Assuming that the defrosting temperature is -45℃, the temperature of the control board is -45℃. The second temperature threshold is -30℃. The first temperature threshold is -40℃. The first operating power is 2W. The second operating power is 1W. Since the temperature of the control board -45℃ is lower than the first temperature threshold -40℃, the heating device is turned on and runs at 2W. The temperature sensor detects and sends the defrosting temperature again, assuming that the current defrosting temperature is -35℃. Since the temperature of the control panel -35°C is higher than the first temperature threshold -40°C and lower than the second temperature threshold -30°C, the power of the heating device is adjusted to 1W. The heating device is turned off until the defrosting temperature detected is higher than -30°C.
