In order for any person skilled in the art to implement and use the present invention, the following description is given. In the following description, details are set forth for the purpose of explanation. It should be understood that those of ordinary skill in the art can recognize that the present invention can be implemented without these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid unnecessary details from obscuring the description of the present invention. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope that conforms to the principles and features disclosed in the present application.
[0039] The embodiments of the present application provide a control method, device, server, and storage medium for a refrigerator, which will be described in detail below respectively.
[0040] A refrigerator is a commonly used household refrigeration device. The refrigeration system of the refrigerator includes a compressor, a condenser, a throttling device, and an evaporator. The compressor, the condenser, the throttling device, and the evaporator are connected in sequence, and the outlet of the evaporator is communicated with the inlet of the compressor to form a closed loop for refrigerant flow. Among them, low-temperature liquid refrigerant flows in the evaporator to provide cooling capacity to the refrigerating compartment of the refrigerator. However, the temperature of the liquid refrigerant in the evaporator is low, and the air in the refrigerating compartment is in a humid state. During the refrigeration process, the fan drives the air to exchange heat with the evaporator. During the heat exchange process, moisture is likely to condense on the surface of the evaporator, causing the evaporator to frost, thereby reducing the heat exchange efficiency of the evaporator and resulting in abnormal refrigeration in the refrigerating compartment. Therefore, it is necessary to defrost the evaporator, and the defrost water is discharged through a drain pipe. However, because the defrost water is at a low temperature, it is easy to cause ice blockage of the drain pipe and unable to be discharged normally, thereby causing water leakage in the refrigerator and water leakage in the compressor compartment. Therefore, the prior art adopts timed heating of the drain pipe to avoid ice blockage of the drain pipe. However, at a relatively high ambient temperature, timed heating of the drain pipe causes waste of electric energy, and there is a technical problem of high energy consumption. This is mainly because at a relatively high ambient temperature, the drain pipe is not easy to freeze; when the drain pipe is heated regularly, more heat is radiated into the environment rather than used for deicing, resulting in waste of electric energy.
[0041] Therefore, in the technical solution of the embodiment of the present application, a refrigerator is provided. The refrigerator includes a drain pipe and a heating element, and the heating element is arranged on the drain pipe. The drain pipe is used for discharging defrost water. The refrigerator further includes a controller configured to execute the control method provided in the embodiment of the present application to solve the technical problem of waste of electric energy caused by timed heating of the drain pipe and high energy consumption.
[0042] Refer to Figure 1 As shown, the control method of the refrigerator includes:
[0043] S100, obtain the ambient temperature;
[0044] S200, obtain the pipe temperature of the drain pipe;
[0045] S400, if the ambient temperature is greater than the preset ambient temperature, then at the first operation duration after the refrigerator starts running in the defrost mode, control the heating element to be in the heating state;
[0046] S600, when the pipe temperature is greater than the first preset pipe temperature, control the heating element to switch from the heating state to the stop working state.
[0047] In the technical solution of the embodiment of the present application, when the ambient temperature is higher than the preset ambient temperature and at the first operation duration after the refrigerator starts to operate in the defrosting mode, the heating element is controlled to be in the heating state, so that after the defrosting water begins to be generated and when the pipe temperature of the drain pipe begins to decrease and is likely to cause ice blockage of the drain pipe, the heating element starts to be in the heating state, so that the defrosting water always flows in the drain pipe in a liquid state or the remaining defrosting water is prevented from freezing; and when the pipe temperature is greater than the first preset temperature, the pipe temperature can keep the defrosting water always flowing in the drain pipe in a liquid state or increase the temperature of the remaining defrosting water to prevent it from freezing. In the technical solution of the present application, when the ambient temperature is relatively high, the heating element starts to heat the drain pipe after a period of time after defrosting, and stops heating the drain pipe after the pipe temperature of the drain pipe is higher than the first preset temperature, aiming to start heating the heating element only when there is defrosting water flowing, so as to solve the technical problem of waste of electric energy caused by timed heating of the drain pipe at a relatively high ambient temperature and high energy consumption.
[0048] It should be noted that when the ambient temperature is higher than the preset ambient temperature, if the refrigerator is not defrosting, at this time, the pipe temperature of the drain pipe is close to the ambient temperature. Even if there is remaining defrosting water in the drain pipe, it will not cause ice blockage of the drain pipe, and thus the heating element has been in the stopped heating state. In the embodiment, the preset ambient temperature is set between 10°C and 15°C, such as 12°C. For example, after the ambient temperature is higher than 12°C, only after defrosting, there is a possibility of ice blockage in the drain pipe; and when there is no defrosting, since the temperature of the drain pipe is close to the ambient temperature, there is no possibility of ice blockage.
[0049] In the embodiment, the first preset ambient temperature is 4°C to 6°C. When the pipe temperature is heated above 4°C to 6°C, the possibility of ice blockage in the drain pipe is significantly reduced, so the heating of the heating element is stopped.
[0050] In the above embodiments, the ambient temperature can be obtained by the refrigerator connecting to the network or measured by a temperature sensor provided on the refrigerator. A temperature sensor is provided on the drain pipe for sensing the temperature of the drain pipe; the temperature sensor can be built into the drain pipe to be able to monitor the internal temperature state of the drain pipe in real time.
[0051] In the embodiment, step S200 can be executed when the heating element starts to heat or before the heating element starts to heat.
[0052] As an alternative implementation of the above embodiment, such as Figure 2As shown, the control method further includes: S500. If the ambient temperature is less than the preset ambient temperature and the pipe temperature is less than the second preset pipe temperature, then control the heating element to be in the heating state. That is, at low ambient temperatures, in order to prevent ice blockage caused by residual defrost water, when the pipe temperature is less than the second preset pipe temperature, the heating element starts to heat the drain pipe, so that the defrost water existing in the drain pipe is always in a liquid state, rather than a frozen state; wherein, the first preset pipe temperature is greater than the second preset pipe temperature.
[0053] In this embodiment, the control mode of the heating element is switched according to the ambient temperature; when the ambient temperature is relatively high, within a certain period of time after defrosting starts, the heating element starts to heat; when the ambient temperature is relatively low, after the pipe temperature is less than the second preset temperature, the heating element starts to heat. After the ambient temperature is higher than the preset ambient temperature, only after defrosting, there is a possibility of ice blockage in the drain pipe, and when there is no defrosting, since the temperature of the drain pipe is close to the ambient temperature, there is no possibility of ice blockage. When the ambient temperature is low, the working state of the heating element is controlled by the pipe temperature, so that the residual defrost water in the drain pipe can be in a liquid state rather than a solid state.
[0054] In addition, if the ambient temperature is less than the preset ambient temperature, and after the refrigerator starts defrosting, the defrost water will reduce the pipe temperature to the second preset pipe temperature, then controlling the heating element to be in the heating state at this time will also avoid ice blockage.
[0055] Combined Figure 1 and Figure 2 As shown, the embodiment of the present application provides two control modes for the heating element. By obtaining the ambient temperature, when the ambient temperature is greater than the preset ambient temperature, the heating element is turned on only after the refrigerator defrosts; when the ambient temperature is less than the preset ambient temperature, the heating element is turned on only when the pipe temperature is less than the second preset pipe temperature.
[0056] In this embodiment, the second preset temperature is 0 - 2°C. In order to reduce the risk of ice blockage, the second preset temperature is selected to be between 1°C and 2°C, such as 1.5°C or 2°C.
[0057] As an alternative implementation of the above embodiment, as Figure 3 shown, controlling the heating element to be in the heating state at the first operation duration after the refrigerator starts running in the defrost mode includes:
[0058] S411. When the refrigerator finishes running in the defrost mode, control the heating element to be in the heating state; or
[0059] S412. At the second operation duration after the refrigerator finishes running in the defrost mode, control the heating element to be in the heating state.
[0060] In some embodiments, at the end of the defrosting mode operation, when the defrosting water is flowing in the pipeline, the heating element is controlled to be in the heating state at this time to ensure that the defrosting water can exist and flow out in a liquid state; or at the second operation duration after the refrigerator finishes operating in the defrosting mode, most of the defrosting water has flowed out, but some defrosting water remains in the drain pipe. Since the drain pipe continuously cools down during drainage, the remaining defrosting water has a risk of ice blockage. At this time, heating the drain pipe can heat the remaining defrosting water to avoid freezing of the remaining defrosting water. In the embodiment, the second operation duration is usually set to 8 - 12 minutes, preferably 10 minutes.
[0061] As another alternative implementation of the above embodiment, as Figure 4 shown, before controlling the heating element to be in the heating state at the first operation duration after the refrigerator starts operating in the defrosting mode, the control method further includes:
[0062] S301, obtaining the defrosting gear of the refrigerator;
[0063] S302, determining the first operation duration according to the defrosting gear.
[0064] In this embodiment, there is a negative correlation between the defrosting gear and the first operation duration. The higher the defrosting gear, the shorter the corresponding first operation duration. The lower the defrosting gear, the longer the corresponding first operation duration. When the defrosting gear is higher, more defrosting water is generated in a short time. At this time, the pipeline temperature drops faster, and the risk of ice blockage in the drain pipe is higher. Therefore, the first operation duration is shorter.
[0065] For example, when the defrosting gear is low, the heating element is turned on 15 minutes after the defrosting ends; when the defrosting gear is medium, the heating element is turned on at the end of the defrosting; when the defrosting gear is high, the heating element is turned on at the middle time from the start to the end of the defrosting.
[0066] In some other embodiments, before controlling the heating element to be in the heating state at the first operation duration after the refrigerator starts operating in the defrosting mode, the control method further includes:
[0067] Determining the first operation duration according to the ambient temperature.
[0068] In this embodiment, the higher the ambient temperature, the longer the first operating duration. The lower the ambient temperature, the shorter the first operating duration. This is mainly because when the ambient temperature is higher, the initial temperature of the drain pipe is higher, and the possibility of frost melting water causing ice blockage is lower. Therefore, the first operating duration is set longer. For example, when the first operating duration determined according to the ambient temperature is greater than a preset duration, and the preset duration is greater than the defrosting duration; at this time, it indicates that the ambient temperature is sufficient and the possibility of the drain pipe being blocked by ice is extremely low. At this time, the heating element is controlled to be in a stopped heating state.
[0069] As an alternative implementation of the above embodiment, as Figure 5 shown, controlling the heating element to be in a heating state includes:
[0070] S421, controlling the heating element to operate at a first power;
[0071] S422, obtaining the flow rate of the frost melting water;
[0072] S423, if the flow rate is less than a preset flow rate, then control the heating element to operate at a second power; the second power is greater than the first power.
[0073] In the embodiment, when the heating element starts to operate at the first power, the flow rate of the frost melting water is less than the preset flow rate, and the possibility of ice blockage in the drain pipe is relatively high. For this reason, the power of the heating element is increased to the second power so that the ice in the drain pipe can melt quickly and avoid water leakage caused by the accumulation of frost melting water.
[0074] In some embodiments, the preset flow rate is related to the defrosting gear. For example, when the defrosting gear is high, the amount of frost melting water generated in a short time is high, so the preset flow rate is larger. For example, when the defrosting gear is low, the amount of frost melting water generated in a short time is small, so the preset flow rate is smaller.
[0075] As an alternative implementation of the above embodiment, the heating element is a heating wire; the heating wire is embedded in the drain pipe; and / or the heating wire is helically arranged along the circumferential direction of the drain pipe and extends along the axial direction. In the embodiment, embedding the heating wire in the drain pipe helps the drain pipe to be heated and respond quickly, overcoming the deficiency in the prior art that the heating element is arranged outside the drain pipe resulting in slow heating response. In addition, the area where the drain pipe is blocked by ice is random. For this reason, in some embodiments, the heating wire is helically arranged along the circumferential direction of the drain pipe and extends along the axial direction, so that the heating wire can heat each area of the drain pipe. In some embodiments, the heating wire is embedded in the drain pipe, and the heating wire is helically arranged along the circumferential direction of the drain pipe and extends along the axial direction.
[0076] In order to better implement the control method of the refrigerator in the embodiments of the present application, on the basis of the control method of the refrigerator, a control module of the refrigerator is further provided in the embodiments of the present application, asFigure 6 As shown, the control module of the refrigerator includes:

[0079] Optionally, in the control module, the control module is further configured to: if the ambient temperature is less than the preset ambient temperature and the temperature of the pipe is less than a second preset pipe temperature, control the heating element to be in a heating state.
