[0002] With the progress of society, users' requirements for refrigerators are also increasing.

However, considering that refrigerators of the same model are sold to different regions, the climate in each region is different; even in the same region, the climate will change with the change of seasons. In this case, if the heating temperature of the defrosting pipe when working is set too high, most users will feel that the refrigerator is too hot, which will result in a poor experience; if the heating temperature of the defrosting pipe when working is set too low, the defrosting will not be effective in most cases.

[0022] Typical embodiments embodying the principles of the application will now be described in detail with reference to the drawings. It should be appreciated that the present application can be embodied in various forms without being limited to embodiments set forth herein; and specific expressions and drawings in the description are intended to be illustrative in nature rather than to limit the present application.

[0023] In the description of the present application, the terms "first", "second", etc. are used only for the purpose of description, and should not be understood as indicating or implying relative importance. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0024] In the description of the present application, the terms "some embodiments", "one embodiment", etc. mean that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present description, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0025] The present application provides a refrigerator, which comprises a cabinet and a refrigeration system. The refrigeration system comprises a compressor, a condenser, a throttling element, an evaporator, a defrosting pipe and a control valve.

[0026] The refrigerant circulates through various components in the refrigeration system to achieve the refrigeration effect. The main flow process of the refrigerant in the various components is as follows: the refrigerant enters the condenser after passing through the compressor; enters the throttling element after passing through the condenser; enters the evaporator after passing through the throttling element; and enters the compressor after passing through the evaporator.

[0027] Specifically, the compressor compresses the refrigerant gas at high temperature and high pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The throttling element expands the liquid-phase refrigerant at high temperature and high pressure condensed in the condenser into low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the throttling element and returns the refrigerant gas at low temperature and low pressure to the compressor. The evaporator can achieve the refrigeration effect by exchanging heat with the material to be cooled through the evaporation of the latent heat of the refrigerant.

[0028] In this application, the drain tube and the control valve are located on the refrigerant passage between the compressor and the throttling element, and the drain tube is in communication with the condenser. During the process of the refrigerant flowing from the compressor to the throttling element: part of it flows through the condenser, and part of it flows through the drain tube. The control valve is used to adjust the refrigerant flow through the drain tube.

[0029] When the refrigerant flows through the drain tube, the drain tube provides heat energy using the system condensation, thereby heating the area where it is located and preventing condensation from occurring in the area. Generally, the greater the refrigerant flow through the drain tube, the more heat energy the drain tube provides.

[0030] In some embodiments, the drain tube is provided on the refrigerator U-shell. When the refrigerant flows through the drain tube, the drain tube provides heat energy, thereby heating the refrigerator U-shell and preventing condensation from occurring in the refrigerator U-shell.

[0031] In some embodiments, the drain tube is provided on the refrigerator middle beam. When the refrigerant flows through the drain tube, the drain tube provides heat energy, thereby heating the refrigerator middle beam and preventing condensation from occurring in the refrigerator middle beam.

[0032] On the basis of the refrigerator, the application provides a method for removing condensation from the refrigerator, Figure 1 A flowchart of the method for removing condensation is shown:

[0033] Step S110, obtaining the ambient temperature of the environment where the refrigerator is located and the ambient humidity of the environment where the refrigerator is located;

[0034] Step S120, based on the ambient temperature and the ambient humidity, controlling the control valve to adjust the refrigerant flow through the drain tube.

[0035] The execution subject of the defrosting method in the present application can be the refrigeration system in the refrigerator, can be the electrical control system in the refrigerator, or can be other systems or components with control valve control capability. For the purpose of brief description, the execution subject of the defrosting method will be omitted in the following description of the defrosting method.

[0036] In the present application, the control valve is controlled to adjust the refrigerant flow through the defrosting pipe based on the ambient temperature of the environment where the refrigerator is located and the ambient humidity of the environment where the refrigerator is located.

[0037] In some embodiments, the refrigerator further comprises an ambient temperature sensor and an ambient humidity sensor. The ambient temperature of the environment where the refrigerator is located and the ambient humidity of the environment where the refrigerator is located are obtained by obtaining the ambient temperature through the ambient temperature sensor and obtaining the ambient humidity through the ambient humidity sensor.

[0038] In this embodiment, the refrigerator is provided with an ambient temperature sensor for measuring the ambient temperature of the environment where the refrigerator is located and an ambient humidity sensor for measuring the ambient humidity of the environment where the refrigerator is located. The ambient temperature is obtained through the ambient temperature sensor, and the ambient humidity is obtained through the ambient humidity sensor.

[0039] In some embodiments, the refrigerator further comprises a wireless communication device. The ambient temperature of the environment where the refrigerator is located and the ambient humidity of the environment where the refrigerator is located are obtained by obtaining the ambient temperature and the ambient humidity through the wireless communication device.

[0040] In this embodiment, the refrigerator is provided with a wireless communication device for communication. The wireless communication device can communicate with other communication devices in the same local area network, so that the ambient temperature and the ambient humidity can be obtained through the communication between the wireless communication device and the other communication devices; the wireless communication device can also communicate with a server located in the cloud, so that the ambient temperature and the ambient humidity can be obtained through the communication between the wireless communication device and the server.

[0041] In this way, the refrigerator can be an Internet of Things device in the Internet of Things, and defrosting can be performed through communication with other Internet of Things devices.

[0042] In some embodiments, based on the ambient temperature and the ambient humidity, the control valve is controlled to adjust the refrigerant flow through the defrosting pipe, including: based on an empirical formula composed of the ambient temperature and the ambient temperature as parameters, the control valve is controlled to adjust the refrigerant flow through the defrosting pipe.

[0043] In this embodiment, the relationship between the ambient temperature and humidity and the refrigerant flow rate through the defrosting pipe is determined in advance according to experience when the heat energy emitted by the defrosting pipe matches the environment of the refrigerator, and then the corresponding empirical formula is obtained. Through the empirical formula, the refrigerant flow rate through the defrosting pipe is determined by taking the ambient temperature and humidity as parameters, and then the control valve is controlled to adjust the refrigerant flow rate through the defrosting pipe.

[0044] In some embodiments, based on the ambient temperature and humidity, the control valve is controlled to adjust the refrigerant flow rate through the defrosting pipe, including:

[0045] Based on the ambient temperature and humidity, the dew point temperature of the condensation of the refrigerator is determined;

[0046] Based on the dew point temperature, the control valve is controlled to adjust the refrigerant flow rate through the defrosting pipe, wherein the refrigerant flow rate is positively correlated with the dew point temperature.

[0047] In this embodiment, the dew point temperature of the condensation of the refrigerator is determined based on the ambient temperature and humidity, and then the control valve is controlled to adjust the refrigerant flow rate through the defrosting pipe based on the dew point temperature. The refrigerant flow rate through the defrosting pipe is positively correlated with the dew point temperature.

[0048] By this method, in general, the higher the dew point temperature of the environment of the refrigerator, the greater the refrigerant flow rate through the defrosting pipe, and the more heat energy emitted by the defrosting pipe.

[0049] In some embodiments, the defrosting pipe in the refrigeration system includes a first defrosting pipe and a second defrosting pipe, and the control valve in the refrigeration system is used to adjust the first refrigerant flow rate through the first defrosting pipe and the second refrigerant flow rate through the second defrosting pipe. The first defrosting pipe and the second defrosting pipe are both located on the refrigerant passage between the compressor and the throttling element, and are in communication with the condenser.

[0050] In this embodiment, two defrosting pipes are provided in the refrigerator, which are a first defrosting pipe and a second defrosting pipe. The first defrosting pipe and the second defrosting pipe are both located on the refrigerant passage between the compressor and the throttling element, and are in communication with the condenser.

[0051] It can be understood that according to specific application requirements, in some embodiments of the present application, the defrosting pipe in the refrigeration system can have three, four or more, and the defrosting principle is similar to that of the refrigeration system with two defrosting pipes, so it is not repeated here.

[0052] The defrosting principle of the refrigeration system with two defrosting pipes is described below.

[0053] In some embodiments, the decondensation pipe in the refrigeration system includes a first decondensation pipe and a second decondensation pipe. Based on the dew point temperature, controlling the control valve to regulate the refrigerant flow through the decondensation pipe includes:

[0054] If the dew point temperature is not higher than the reference temperature, then control the control valve to close the passage of the refrigerant to the first dew pipe;

[0055] If the dew point temperature is higher than the reference temperature, the control valve is controlled to open the passage for the refrigerant to flow to the first dew pipe.

[0056] In this embodiment, a reference temperature is preset for whether to close the refrigerant flow to the first decondensation pipe (the reference temperature is generally lower than the heating temperature of the second decondensation pipe under any ambient temperature and humidity conditions). If the dew point temperature is not higher than the reference temperature, the control valve closes the refrigerant flow to the first decondensation pipe. In this case, the second decondensation pipe operates and heats up to perform decondensation. If the dew point temperature is higher than the reference temperature, the control valve opens the refrigerant flow to the first decondensation pipe. In this case, both the first and second decondensation pipes operate and heat up together to perform decondensation.

[0057] This method allows for decondensation by using a single section of the dew point pipe when the dew point temperature of the refrigerator's environment is low, and by using both sections of the dew point pipe when the dew point temperature is high. This ensures effective decondensation while reducing energy consumption.

[0058] In some embodiments, the first refrigerant flow rate through the first condensate pipe is higher than the second refrigerant flow rate through the second condensate pipe.

[0059] In this embodiment, when the refrigerant flow path to the first decondensation pipe is opened, the first refrigerant flow rate through the first decondensation pipe is higher than the second refrigerant flow rate through the second decondensation pipe; that is, when the refrigerant flow path to the first decondensation pipe is opened, the first decondensation pipe can provide more heat energy than the second decondensation pipe.

[0060] This method utilizes a second dew point pipe, which provides less heat, to remove condensation when the dew point temperature is low; conversely, when the dew point temperature is high, both the first and second dew point pipes work together to remove condensation. This ensures both effective and efficient dew removal.

[0061] In some embodiments, the first condenser pipe in the refrigeration system is connected in parallel with the condenser; meanwhile, the inlet of the second condenser pipe is connected in series with the outlet of the condenser.

[0062] For details, please refer to Figure 2 An optional connection structure for the first decondensation pipe and the second decondensation pipe in this embodiment is described by way of example, as well as an optional connection structure for the control valve.

[0063] Figure 2 A refrigeration system of a refrigerator provided in some embodiments of the present application is shown. Referring to FIG. 1, in this embodiment, the refrigeration system comprises a compressor, a condenser, a throttling element, an evaporator, a defrosting pipe 1, a defrosting pipe 2, and a control valve 1 and a control valve 2. The defrosting pipe 1 is in parallel communication with the condenser. The inlet of the defrosting pipe 2 is in series communication with the outlet of the condenser. The control valve 1 is located between the outlet of the compressor, the inlet of the condenser, and the inlet of the defrosting pipe 1. The control valve 2 is located between the outlet of the condenser, the outlet of the defrosting pipe 1, and the inlet of the defrosting pipe 2. Figure 2

[0064] When the control valve 1 closes the A valve port and opens the B valve port, and the control valve 2 closes the C valve port and opens the D valve port, the passage of the refrigerant flowing to the defrosting pipe 1 is closed. In this case, the defrosting pipe 2 works to heat and defrost.

[0065] When the control valve 1 opens the A valve port and opens the B valve port, and the control valve 2 opens the C valve port and opens the D valve port, the passage of the refrigerant flowing to the defrosting pipe 1 is opened. In this case, the defrosting pipe 1 and the defrosting pipe 2 both work together to defrost.

[0066] In some embodiments, the defrosting process of the refrigerator is controlled by the following method: Figure 2

[0067] The ambient temperature and the ambient humidity of the environment in which the refrigerator is located are obtained, and based on the ambient temperature and the ambient humidity, the dew point temperature T1 of the condensation of the refrigerator is determined.

[0068] If T1 is less than or equal to the reference temperature T2, the control valve 1 is controlled to close the A valve port and open the B valve port, and the control valve 2 is controlled to close the C valve port and open the D valve port. In this case, the refrigerant flows from the compressor, through the B valve port of the control valve 1, through the condenser, through the D valve port of the control valve 2, through the defrosting pipe 2, through the throttling element, into the evaporator, and then into the compressor.

[0069] If T1 is greater than the reference temperature T2, the control valve 1 is controlled to open the A valve port and open the B valve port, and the control valve 2 is controlled to open the C valve port and open the D valve port. In this case, a first portion of the refrigerant flows from the compressor, through the A valve port of the control valve 1, and then to the defrosting pipe 1; a second portion of the refrigerant flows from the compressor, through the B valve port of the control valve 1. The first portion of the refrigerant and the second portion of the refrigerant flow through the C valve port and the D valve port of the control valve 2, respectively, merge at the control valve 2, and then flow through the defrosting pipe 2, through the throttling element, into the evaporator, and then into the compressor.

[0070] In some embodiments, the inlet of the first defrosting pipe of the refrigeration system is in series communication with the outlet of the condenser; at the same time, the inlet of the second defrosting pipe is in series communication with the outlet of the condenser, and the second defrosting pipe is in parallel communication with the first defrosting pipe. ​​

[0071] Specifically, referring to Figure 3 The optional connection structure of the first drain pipe and the second drain pipe in this embodiment is described exemplarily, and the optional connection structure of the control valve is also described correspondingly.

[0072] Figure 3 A refrigeration system of a refrigerator provided in some embodiments of the present application is shown. Referring to Figure 3 In this embodiment, the refrigeration system comprises a compressor, a condenser, a throttling element, an evaporator, a drain pipe 1, a drain pipe 2, and a control valve 1 and a control valve 2. The inlet of the drain pipe 1 is in series communication with the outlet of the condenser. The inlet of the drain pipe 2 is in series communication with the outlet of the condenser, and the drain pipe 2 is in parallel communication with the drain pipe 1. The control valve 1 is located between the outlet of the condenser, the inlet of the drain pipe 1, and the inlet of the drain pipe 2. The control valve 2 is located between the outlet of the drain pipe 1, the outlet of the drain pipe 2, and the inlet of the throttling element.

[0073] When the control valve 1 closes the A valve port and opens the B valve port, and the control valve 2 closes the C valve port and opens the D valve port, the passage of the refrigerant flowing to the drain pipe 1 is closed, and in this case, the drain pipe 2 works to heat and perform dew removal.

[0074] When the control valve 1 opens the A valve port and opens the B valve port, and the control valve 2 opens the C valve port and opens the D valve port, the passage of the refrigerant flowing to the drain pipe 1 is opened, and in this case, the drain pipe 1 and the drain pipe 2 both work together to perform dew removal.

[0075] In some embodiments, the dew removal process of the refrigerator is controlled by the following method: Figure 3

[0076] The ambient temperature and the ambient humidity of the environment in which the refrigerator is located are obtained, and based on the ambient temperature and the ambient humidity, the dew point temperature T1 of the condensation of the refrigerator is determined.

[0077] If T1 is less than or equal to the reference temperature T2, the control valve 1 is controlled to close the A valve port and open the B valve port, and the control valve 2 is controlled to close the C valve port and open the D valve port. In this case, the refrigerant flows from the compressor, passes through the B valve port of the control valve 1, flows through the condenser, passes through the D valve port of the control valve 2, flows through the drain pipe 2, and then enters the evaporator through the throttling element and enters the compressor again.

[0078] If T1 is greater than the reference temperature T2, the control valve 1 is controlled to open the A valve port and open the B valve port, and the control valve 2 is controlled to open the C valve port and open the D valve port. In this case, a first part of the refrigerant flows from the compressor, passes through the A valve port of the control valve 1, and then flows to the drain pipe 1; a second part of the refrigerant flows from the compressor, passes through the B valve port of the control valve 1. The first part of the refrigerant and the second part of the refrigerant flow through the C valve port and the D valve port of the control valve 2, respectively, merge at the control valve 2, and flow through the drain pipe 2, and then enter the evaporator through the throttling element and enter the compressor again. ​

[0079] In an embodiment, the dew removal pipe is in parallel communication with the condenser.

[0080] Specifically, referring to Figure 4 The optional connection structure of the first dew removal pipe and the second dew removal pipe in this embodiment is described exemplarily, and the optional connection structure of the control valve is also described.

[0081] Figure 4 A refrigeration system of a refrigerator provided in some embodiments of the present application is shown. Referring to Figure 4 In this embodiment, the refrigeration system comprises a compressor, a condenser, a throttling element, an evaporator, a dew removal pipe 1 and a control valve 1. The dew removal pipe 1 is in parallel communication with the condenser. The control valve 1 is located between the outlet of the compressor, the inlet of the dew removal pipe 1 and the inlet of the condenser.

[0082] The control valve 1 is mainly used for shunting the refrigerant flow out of the compressor. By shunting through the control valve 1, the refrigerant flow through the dew removal pipe 1 is controlled.

[0083] In some embodiments, the dew removal process of the refrigerator is controlled by Figure 2

[0084] The ambient temperature and the ambient humidity of the environment where the refrigerator is located are obtained, and based on the ambient temperature and the ambient humidity, the dew point temperature T1 of the condensation of the refrigerator is determined. Then, the control valve 1 is controlled to adjust the refrigerant flow Q1 through the dew removal pipe 1 according to T1. As T1 increases, Q1 increases accordingly. Wherein, let the total refrigerant flow be Q, and let the refrigerant flow through the condenser be Q2, then Q = Q1 + Q2, and Q2 is greater than 0.

[0085] From the above description, it can be seen that the refrigerator and the dew removal method provided by the present application can meet the dew removal needs in different environments: when the dew point temperature of the environment where the refrigerator is located is low, the dew removal pipe removes dew at a matching low heating temperature; when the dew point temperature of the environment where the refrigerator is located is high, the dew removal pipe removes dew at a matching high heating temperature. Therefore, whether the working area is different or the season changes, the refrigerator and the dew removal method provided by the present application can adapt to the environment where the refrigerator is located.

[0086] At the same time, this method also reduces energy consumption. In some embodiments, for a refrigerator originally installed with heating wires for dew removal, by applying the present application, the heating wires can be removed, thereby being more energy-saving and safer.

[0087] In an exemplary embodiment, the present application provides a dew removal electronic device of a refrigerator, comprising a processor and a memory, wherein the memory has computer readable instructions stored thereon, and the computer readable instructions are executed by the processor to implement the dew removal method of the refrigerator as described above. ​

[0088] Moreover, the application can also be implemented by hardware circuit or by combination of hardware circuit and software instruction, and therefore, the implementation of the application is not limited to any specific hardware circuit, software and combination of both.

[0089] In an exemplary embodiment, the application provides a computer readable storage medium, which stores a computer program, and the computer program is executed by a processor to implement the defrosting method of the refrigerator as described above. The computer readable storage medium can be included in the defrosting electronic device as described in the above embodiments, or can exist separately without being assembled into the defrosting electronic device.

[0090] Although the application has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation. Since the application can be embodied in various forms without departing from the spirit or essential characteristics thereof, it is understood that the exemplary embodiments are not to limit the scope of the application as defined in the claims and their equivalents, and all changes and modifications that come within the scope of the claims or their equivalents are therefore intended to be embraced by the appended claims.
