Description

Technical Field

[0001] The embodiments of the present application relate to the field of household appliances, and more specifically, to a refrigerator and a control method of the refrigerator. Background Art

[0002] Air temperature regulating equipment is usually not installed in home kitchens. The temperature in the kitchen is higher in summer and lower in winter, which may cause users to feel uncomfortable when cooking in the kitchen.

[0003] However, refrigerators, as widely used electrical appliances in households, are usually placed in kitchens. Therefore, how to use refrigerators to adjust the temperature in the kitchen needs to be solved. Summary of the invention

[0004] The embodiments of the present application provide a refrigerator and a method for controlling the refrigerator, which can cool or heat the external environment through the refrigerator, thereby achieving the effect of regulating the external environment and improving the user experience.

[0005] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0006] A box body, configured with at least one storage chamber;

[0007] A refrigeration system is arranged in the box;

[0008] First condenser;

[0009] An air supply channel is provided with an air inlet connected to the storage chamber and capable of selectively being switched on and off, and an air outlet connected to the outside of the box;

[0010] an air supply fan, arranged in the air supply passage;

[0011] A second condenser is disposed in the air supply channel;

[0012] a switch element, connecting the first condenser and the second condenser; when the switch element is in a first state, the first condenser is disconnected from the second condenser; when the switch element is in a second state, the first condenser is connected to the second condenser;

[0013] A controller is disposed in the box, and the controller is configured as follows:

[0014] When receiving a first instruction to start the cooling mode, determining whether a cooling condition is met;

[0015] If the cooling condition is met, the switch element is controlled to be in the first state, the air inlet is opened, and the air supply fan is controlled to operate, so as to blow the cold air in the storage room from the air outlet to the outside of the box through the air supply channel to cool the external environment;

[0016] The controller is also configured to:

[0017] When receiving a second instruction to start the heating mode, determining whether a heating condition is met;

[0018] If the heating conditions are met, the switch element is controlled to be in the second state so that refrigerant flows through the second condenser to provide heat for the air supply channel; and the air inlet is closed, and the air supply fan is controlled to operate so that the heat in the air supply channel is blown to the outside of the box through the air outlet to heat the external environment.

[0019] In the present application, by providing an air inlet and an air supply fan that are connected to the storage room of the refrigerator and can be selectively turned on and off, when the external environment needs to be cooled, the air inlet can be controlled to open, and the air supply fan can be controlled to run, so that the cold in the refrigerator storage room can escape from the air inlet and be blown to the external environment by the air supply fan, thereby achieving cooling for the external environment. In addition, in addition to the original condenser of the refrigerator, a second condenser is also provided. When the external environment needs to be heated, the refrigerant can pass through the newly added second condenser, and the second condenser can release heat, which is blown to the external environment by the air supply fan, thereby achieving heating for the external environment.

[0020] In some embodiments of the present application, the refrigeration system further includes a compressor; and the refrigeration condition includes at least one of the following:

[0021] The time interval between the current moment and the last cooling mode end moment is greater than or equal to the first preset time length;

[0022] During a second preset time period before the current moment, the startup rate of the compressor is less than or equal to the first preset startup rate;

[0023] During a third preset time period before the current moment, the door of the refrigerator is in a closed state;

[0024] The ambient temperature is greater than or equal to the first preset temperature.

[0025] In the present application, since refrigeration is to release the coldness in the storage room to the external environment, by having the interval between two refrigerations be greater than or equal to the first preset time, the refrigerator can be given enough time to generate coldness, thereby avoiding a large impact on the coldness of the storage room when refrigerating the external environment. The compressor startup rate is low, which means that the user opens and closes the door less frequently, and the temperature in the storage room is relatively stable. The door of the refrigerator is in a closed state for a period of time, so that the temperature in the storage room is relatively stable. The refrigeration mode is turned on only when the ambient temperature is high, which can reduce the situation where the refrigeration mode is turned on due to user error.

[0026] In some embodiments of the present application, the controller is configured as follows:

[0027] If the refrigeration condition is met, the compressor is controlled to continue to operate until the temperature in the storage room is lower than a preset temperature, and the difference between the temperature and the preset temperature is greater than or equal to a preset value, and then the compressor is controlled to stop operating;

[0028] The switch element is controlled to be in the first state, and the air inlet is opened.

[0029] In the present application, after the temperature in the storage room is lower than a certain value of the preset temperature, the air inlet is opened, so that when the refrigerator uses the cold energy in the storage room to cool the external environment, the temperature in the storage room will not quickly exceed the preset temperature.

[0030] In some embodiments of the present application, the refrigerator further includes:

[0031] A refrigeration fan is arranged in the box;

[0032] The controller is configured to:

[0033] The air inlet is opened and the refrigeration fan is controlled to operate. After a fourth preset time period, the air supply fan is controlled to operate so as to blow the cold air in the storage room from the air outlet to the outside of the box through the air supply channel to cool the external environment.

[0034] In the present application, when the air inlet is opened, the refrigeration fan is controlled to operate at the same time, and the operation of the refrigeration fan can make the coldness in the storage room more uniform, which is conducive to the coldness to be discharged from the air inlet. After the fourth preset time, the air supply fan is turned on again, and the air supply channel is filled with cold air. The air supply fan can blow the cold air in the air supply channel to the external environment.

[0035] In some embodiments of the present application, the controller is further configured to:

[0036] When a third instruction to close the cooling mode is received, or the running time of the cooling mode reaches a fifth preset time, controlling to close the air inlet;

[0037] After the sixth preset time, the air supply fan is controlled to stop running, and the refrigeration fan and the compressor are controlled to continue running. After the seventh preset time, the refrigeration fan and the compressor are controlled according to the temperature in the storage room and the preset temperature.

[0038] In the present application, the cooling mode is turned off based on the user's instruction or the operation time, which can reduce the significant impact of the long-term opening mode on the temperature in the refrigerator storage room. When the cooling mode is turned off, the air inlet is first closed, and then the air supply fan is turned off after a period of time, so that the air supply fan can blow the cold air remaining in the air supply channel to the external environment. The refrigeration fan and the compressor are controlled to run continuously for a period of time, so that the temperature in the storage room is reduced and the temperature in the storage room is kept relatively uniform.

[0039] In some embodiments of the present application, the refrigeration system further includes a compressor; and the heating condition includes at least one of the following:

[0040] The time interval between the current time and the last time the heating mode ended is greater than or equal to the eighth preset time length;

[0041] During a ninth preset time period before the current moment, the startup rate of the compressor is greater than or equal to a second preset startup rate;

[0042] Within the tenth preset time period before the current moment, the door of the refrigerator is in an open state at least once;

[0043] The ambient temperature is less than or equal to the second preset temperature.

[0044] In this application, since heating is achieved through the operation of the second condenser, by controlling the interval between two heating modes, it is possible to reduce the situation where the refrigerator may be over-refrigerated due to frequent activation of the heating mode, which may affect the food in the refrigerator. A high startup rate and door opening and closing operations over a period of time indicate that the temperature of the compressor is high and the heat dissipation demand is large. At this time, turning on the heating mode can help dissipate heat for the compressor and improve the user's heating experience. Turning on the heating mode only when the ambient temperature is low can avoid the situation where the user accidentally turns on the heating mode.

[0045] In some embodiments of the present application, the controller is configured as follows:

[0046] If the heating condition is met, the control enters the defrost mode. After the defrost is completed, the switch element is controlled to be in the second state so that refrigerant flows through the second condenser to provide heat for the air supply channel.

[0047] In the present application, defrosting is performed before entering the heating mode, which can reduce the situation where excessive frost condenses on the evaporator in the heating mode and affects the normal operation of the refrigerator.

[0048] In some embodiments of the present application, the refrigerator further includes:

[0049] A refrigeration fan is arranged in the box;

[0050] The controller is configured to:

[0051] The air inlet is closed, the refrigeration fan is controlled to run, and the compressor is controlled to run at a speed higher than the target speed. After the eleventh preset time period, the air supply fan is controlled to run to blow the heat in the air supply channel to the outside of the box through the air outlet to heat the external environment.

[0052] In this application, the air inlet is in a closed state, and the cold air in the storage room will not be blown out. The refrigeration fan is controlled to operate, and the operation of the refrigeration fan can make the coldness in the storage room more uniform. After the eleventh preset time, the air supply fan is turned on again. At this time, the air supply channel is full of hot air, and the air supply fan can blow the hot air in the air supply channel to the external environment.

[0053] In some embodiments of the present application, the controller is further configured to:

[0054] When a fourth instruction to turn off the heating mode is received, or the operation time of the heating mode reaches a twelfth preset time, controlling the switch element to switch from the second state to the first state;

[0055] After the thirteenth preset time, the air supply fan is controlled to stop running, and the refrigeration fan and the compressor are controlled to continue running. After the fourteenth preset time, the refrigeration fan and the compressor are controlled according to the temperature in the storage room and the preset temperature.

[0056] In the present application, the heating mode is turned off based on the user's instructions or the operating time, which can reduce the situation where the compressor runs at high speed for a long time due to the heating mode being turned on for a long time, causing the cooling to be too deep. When the heating mode is turned off, the switch element is first controlled to switch to the first state, and then the air supply fan is turned off after a period of time, so that the air supply fan can blow the hot air remaining in the air supply channel to the external environment to avoid heat remaining in the air supply channel. The refrigeration fan and the compressor are controlled to run continuously for a period of time, so that the temperature in the storage room meets the set temperature and the temperature in the storage room is kept relatively uniform.

[0057] In a second aspect, the present application provides a method for controlling a refrigerator, the refrigerator comprising:

[0058] A box body, configured with at least one storage chamber;

[0059] A refrigeration system is arranged in the box;

[0060] First condenser;

[0061] An air supply channel is provided with an air inlet connected to the storage chamber and capable of selectively being switched on and off, and an air outlet connected to the outside of the box;

[0062] an air supply fan, arranged in the air supply passage;

[0063] A second condenser is disposed in the air supply channel;

[0064] a switch element, connecting the first condenser and the second condenser; when the switch element is in a first state, the first condenser is disconnected from the second condenser; when the switch element is in a second state, the first condenser is connected to the second condenser;

[0065] A controller is disposed in the box;

[0066] The method comprises:

[0067] When receiving a first instruction to start the cooling mode, determining whether a cooling condition is met;

[0068] If the cooling condition is met, the switch element is controlled to be in the first state, the air inlet is opened, and the air supply fan is controlled to operate, so as to blow the cold air in the storage room from the air outlet to the outside of the box through the air supply channel to cool the external environment;

[0069] When receiving a second instruction to start the heating mode, determining whether a heating condition is met;

[0070] If the heating conditions are met, the switch element is controlled to be in the second state so that refrigerant flows through the second condenser to provide heat for the air supply channel; and the air inlet is closed, and the air supply fan is controlled to operate so that the heat in the air supply channel is blown to the outside of the box through the air outlet to heat the external environment.

[0071] In a third aspect, the present application provides a computer-readable storage medium, wherein the computer-readable storage medium stores computer-executable instructions, and when the computer-executable instructions are executed by a computer, they are used to implement the method described in the second aspect.

[0072] The computer-readable storage medium provided in the embodiment of the present application can execute the technical solution in the above method embodiment, and its beneficial effects are similar, which will not be repeated here.

[0087] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0088] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0089] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0090] Air conditioning and heating are generally not installed in the kitchen. Thus, when users cook in the kitchen in the summer, the temperature in the kitchen space is too high, which may cause discomfort to the users. When users cook in the kitchen in the winter, the temperature in the kitchen is too low, which may also cause discomfort to the users.

[0091] Based on this, the present application provides a refrigerator, which is connected to the storage room of the refrigerator and can be selectively opened and closed by providing an air inlet and an air supply fan. When the external environment needs to be cooled, the air inlet can be controlled to open, so that the cold in the storage room of the refrigerator can escape from the air inlet and be blown to the external environment by the air supply fan, thereby achieving cooling for the external environment. In addition, in addition to the original condenser of the refrigerator, a new condenser is added. When the external environment needs to be heated, the refrigerant can pass through the newly added condenser, which can release heat, and the heat is blown to the external environment by the air supply fan, thereby achieving heating for the external environment.

[0092] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. The same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0093] First, the structure of the refrigerator provided in some embodiments of the present application is described.

[0094] In one possible implementation, Figure 1 is a schematic diagram of a refrigerator according to some embodiments, such as Figure 1 As shown, the refrigerator 10 includes a cabinet 101 .

[0095] The refrigerator 10 further includes a door body 102 , and the door body 102 is connected to the cabinet 101 .

[0096] The refrigerator 10 further includes a storage chamber, which is disposed in the housing 101 .

[0097] In a possible implementation, the storage chamber includes a refrigerating chamber and / or a freezing chamber, etc.

[0098] The refrigerator 10 further includes a refrigeration system 103 disposed in the housing 101 .

[0099] The refrigerator 10 further includes an air supply duct 104 .

[0100] In a possible implementation, the refrigerator 10 further includes a controller disposed inside the refrigerator body.

[0101] In the embodiment of the present application, the controller may be a microcontroller unit (MCU) or other types of controllers. The embodiment of the present application does not specifically limit the controller.

[0102] The structure of the refrigeration system and the air supply channel 104 in the refrigerator can be seen in Figure 2 shown. Figure 2 A schematic diagram of the interior of a refrigerator according to some embodiments.

[0103] Figure 2 As shown, the refrigeration system 103 includes a compressor 21, a first condenser 22, a capillary tube ( Figure 2 Not shown), evaporator ( Figure 2 not shown).

[0104] The compressor 21, the first condenser 22, the capillary tube and the evaporator are cyclically connected in sequence.

[0105] Exemplarily, the first condenser 22 is a side wall condenser, so that the first condenser 22 is easily connected to the second condenser 26 .

[0106] The first condenser 22 can be arranged in the foam layer of the refrigerator, and the refrigerant flows inside it and dissipates heat through the side wall of the refrigerator. The refrigerant flows inside the second condenser 26 and dissipates heat through the air supply duct.

[0107] The air supply passage 104 is provided with an air inlet 23 which is connected to the storage chamber and can be selectively opened and closed, and an air outlet 24 which is connected to the outside of the box.

[0108] Exemplarily, the air inlet 23 is disposed at the top of the refrigerator compartment.

[0109] An air supply fan 25 and a second condenser 26 are also provided in the air supply passage 104 .

[0110] The second condenser 26 is connected to the capillary tube.

[0111] The air supply fan 25 is arranged at the bottom of the air duct to transport cold and hot air to be discharged from the air outlet.

[0112] A switch element 27 is also provided in the air supply channel 104 , connecting the first condenser 22 , the capillary tube and the second condenser 26 .

[0113] In the present application, when the switch element 27 is in the first state, the first condenser 22 is connected to the capillary tube, and the first condenser 22 is disconnected from the second condenser 26. When the switch element 27 is in the second state, the first condenser 22 is disconnected from the capillary tube, and the first condenser 22 is connected to the second condenser 26.

[0114] Exemplarily, the switch element may be a one-way two-way solenoid valve, or may be other elements with a switch function, which is not limited in the embodiments of the present application.

[0115] like Figure 2 As shown, a one-way stop valve 28 is also provided in the air supply channel 104 . The one-way stop valve 28 is provided on the second condenser 26 for controlling the flow direction of the refrigerant in the second condenser 26 so that the refrigerant can only enter the second condenser 26 from the first condenser 22 .

[0116] like Figure 2 As shown, the refrigerator 10 further includes a cover plate 29 for forming an air supply passage 104 .

[0117] Exemplarily, the cover plate 29 is used to cover the air supply duct, and the outer structural frame may be, for example, a square plastic frame.

[0118] It should be noted that Figure 2 is a side view of a refrigerator. Figure 2 This is just an example for explanation and does not constitute any limitation.

[0119] In the present application, the cycle inside the refrigerator 10 includes:

[0120] The compressor 21 compresses the low-temperature and low-pressure refrigerant gas into a high-temperature and high-pressure gas, and discharges it to the condenser. The condenser cools and condenses the high-temperature and high-pressure refrigerant gas into a high-pressure liquid. The high-pressure liquid refrigerant is throttled and depressurized through the capillary tube to become a low-temperature and low-pressure liquid. The low-temperature and low-pressure liquid refrigerant enters the evaporator, absorbs the heat inside the refrigerator, and then evaporates to become a low-temperature and low-pressure gas, providing cooling for the storage room of the refrigerator. The low-temperature and low-pressure refrigerant gas is then sucked into the compressor 21 to start the next cycle.

[0121] like Figure 2As shown, the second condenser 26 is arranged at a side of the air supply channel 104 away from the air outlet, the air inlet 23 is arranged between the air outlet and the second condenser 26, and the air supply fan 25 is arranged between the air inlet 23 and the air outlet.

[0122] The present application does not limit the specific positions of the second condenser 26 , the air supply fan 25 , the air inlet 23 and the air outlet.

[0123] In this way, by arranging the air inlet 23 between the second condenser 26 and the air outlet, when the air inlet 23 is opened and the wind is blown out from the storage room through the air supply channel 104 and out from the air outlet, the second condenser 26 can reduce the shielding of the wind at the air inlet 23. By arranging the air supply fan 25 between the air inlet 23 and the air outlet, the air supply fan 25 can blow the cold from the air inlet 23 or the heat generated by the second condenser 26 to the air outlet, thereby reducing the dissipation of cold or heat in the air supply channel 104 and improving the effect of using the refrigerator to cool or heat the external environment.

[0124] In the present application, the refrigerator may include three modes, namely, a normal operation mode, a cooling mode and a heating mode. The three modes of the refrigerator are described below.

[0125] Figure 3 Schematic diagram of the internal structure of a refrigerator in a normal operating mode according to some embodiments.

[0126] like Figure 3 As shown, in the normal operating mode, the air inlet 23 is in a closed state, so that the cold air in the storage room circulates inside it, and the opening direction of the switch element 27 is the first condenser 22, that is, there is no refrigerant flowing in the second condenser 26, and the air supply fan 25 is in a closed state. At this time, the refrigerator operates normally, and no cold air or hot air is blown out of the air outlet.

[0127] like Figure 3 As shown, the flow path of the refrigerant in the first condenser 22 is as follows Figure 3 Path A is shown in a clockwise direction.

[0128] The circulation path of cold air in the storage room is as follows Figure 3 Path B is shown in .

[0129] In this way, when the refrigerator is in normal operating mode, the refrigerator does not need to cool or heat the external environment and can operate normally based on the user's settings.

[0130] Figure 4 It is a schematic diagram of the internal structure of a refrigerator when it is in a refrigeration mode according to some embodiments.

[0131] like Figure 4As shown, in the cooling mode, the air inlet 23 is in the open state, so that the cold air in the storage room enters the air supply duct through the air inlet 23, and the switch element 27 is opened in the direction of the first condenser 22, that is, there is no refrigerant flowing in the second condenser 26, and the air supply fan 25 is in the working state. At this time, the refrigerator storage room is still used for normal cooling, and at the same time, the air outlet discharges part of the cold air to reduce the external environment temperature, thereby achieving the effect of cooling the external environment.

[0132] In this way, when the refrigerator is operating normally, the cold air in the refrigerator storage room is blown into the external environment to cool the external environment. For example, when the refrigerator is placed in the kitchen, the refrigerator can cool the kitchen in summer so that the user will not feel too hot when cooking in the kitchen, which can improve the user experience.

[0133] Figure 5 Schematic diagram of the internal structure of a refrigerator in a heating mode according to some embodiments.

[0134] like Figure 5 As shown, in the heating mode, the air inlet 23 is closed, the switch element 27 is turned on in the direction of the second condenser 26, refrigerant flows in the second condenser 26, and heat is dissipated into the air supply duct through the second condenser 26, as shown in the path C in the figure. At this time, the air supply fan 25 is in working state, and the refrigerator storage room is still used for normal cooling. At the same time, the air outlet discharges part of the hot air to increase the temperature of the external environment, thereby achieving the effect of heating the external environment.

[0135] In this way, when the refrigerator is operating normally, the heat generated by the second condenser 26 is blown to the external environment by controlling the refrigerant to flow in the second condenser 26 to heat the external environment. For example, when the refrigerator is placed in a kitchen, the refrigerator can heat the kitchen in winter, so that the user will not feel too cold when cooking in the kitchen, which can improve the user experience.

[0136] Based on the refrigerator described above, a control method for controlling the refrigerator to cool and heat the external environment during the operation of the refrigerator will be described below.

[0137] Combined with the above Figure 2 The structure shown in the figure illustrates the control method of the controller controlling the refrigerator to cool the external environment. For details, please refer to Figure 6 shown. Figure 6 The figure is a flow chart of a method for controlling a refrigerator according to some embodiments.

[0138] Figure 6 As shown, the refrigerator control method may include the following steps:

[0139] S601: When a first instruction to start a cooling mode is received, determine whether a cooling condition is met.

[0140] The first instruction may be generated by the following two possible implementations:

[0141] In a possible implementation, the first instruction is generated by the controller based on the detected temperature of the external environment. Specifically, when the controller detects that the external environment temperature is higher than a certain value, the first instruction is generated. For example, when the controller detects that the external environment temperature is higher than 30°C, the first instruction is generated.

[0142] In another possible implementation, the first instruction is generated when the user chooses to turn on the refrigeration mode through a physical button on the refrigerator or a button on the refrigerator display.

[0143] In the present application, the refrigeration condition includes at least one of the following four refrigeration conditions:

[0144] Refrigeration condition one: the time interval between the current moment and the last time the cooling mode ended is greater than or equal to the first preset time length.

[0145] The first preset duration may be 6 hours or 7 hours, which is not specifically limited in the embodiment of the present application.

[0146] In this way, the situation in which insufficient cold air may be caused in the refrigerator storage compartment due to frequent activation of the refrigeration mode can be reduced.

[0147] Refrigeration condition 2: within a second preset time period before the current moment, the startup rate of the compressor is less than or equal to the first preset startup rate.

[0148] The second preset duration may be 24 hours or 12 hours, which is not limited in the embodiment of the present application. The first preset startup rate may be 85% or 90%, which is not limited in the embodiment of the present application.

[0149] When the startup rate is greater than the first preset startup rate, it means that the refrigerator may be overloaded due to opening and closing the door, putting in food, high ambient temperature, etc., and the compressor is not enough to support the cooling capacity required after the cooling mode is turned on. Therefore, the cooling mode is turned on only when the startup rate of the compressor meets the requirement, so that the cooling capacity generated by the compressor can meet the requirements of maintaining the normal operation of the refrigerator and cooling the external environment.

[0150] Refrigeration condition three: within the third preset time period before the current moment, the door of the refrigerator is in a closed state.

[0151] The third preset time length can be 1 hour or 2 hours, and can be set according to the actual situation of the refrigerator. If the refrigerator can cool quickly, the third preset time length can be a shorter time. Otherwise, the third preset time length can be a longer time. The embodiment of the present application does not limit the third preset time length.

[0152] In this way, when the user opens the refrigerator body, the external heat will be transferred to the storage room, causing the temperature in the storage room to rise, which may lead to insufficient cold air in the storage room. If the external environment is cooled when the storage room is insufficient, the normal operation of the refrigerator may be affected and the effect of cooling the external environment may be reduced. Therefore, the user has not opened or closed the door within the third preset time period before the current moment, so that when the refrigerator cools the external environment, the normal operation of the refrigerator is less affected, and sufficient cold air can be dissipated through the air inlet, which can improve the effect of the refrigerator cooling the external environment.

[0153] Refrigeration condition four: the ambient temperature is greater than or equal to the first preset temperature.

[0154] The first preset temperature may be 30° C. or other temperatures, which is not specifically limited in the embodiment of the present application.

[0155] In this way, the cooling mode is turned on only when the ambient temperature is high, and the user's perception of the cooling capacity is more obvious, which can improve the user experience. In addition, it can avoid the situation where the user accidentally touches the cooling mode when the ambient temperature is low.

[0156] S602: If the cooling conditions are met, the switch element is controlled to be in the first state, the air inlet is opened, and the air supply fan is controlled to operate so as to blow the cold air in the storage room from the air outlet to the outside of the box through the air supply channel to cool the external environment.

[0157] The switch element is controlled to be in the first state so that the refrigerant flows through the compressor, the first condenser, the capillary tube and the evaporator in sequence, so that the evaporator provides cooling for the storage room.

[0158] In the present application, if the refrigeration condition is met, the compressor is controlled to continue to operate until the temperature in the storage room is lower than the preset temperature, and when the difference with the preset temperature is greater than or equal to the preset value, the compressor is controlled to stop operating. The switch element is controlled to be in the first state so that the refrigerant flows through the compressor, the first condenser, the capillary tube and the evaporator in sequence, so that the evaporator provides cooling for the storage room; and the air inlet is opened.

[0159] The preset temperature is the temperature that the storage compartment of the refrigerator needs to reach, which can be set by the user or by default. The preset temperature can be -3°C, etc. The preset value can be 2°C or 3°C. The embodiments of the present application do not specifically limit the preset temperature and preset value.

[0160] For example, when the temperature inside the refrigerator meets the shutdown conditions, the compressor will continue to work for a period of time without stopping until the temperature is lower than the preset temperature of -2°C. This is used to offset the increase in temperature inside the box caused by the cold air being blown out.

[0161] In this way, by controlling the operation of the compressor to make the temperature in the refrigerator storage room lower than the preset temperature, and then opening the air inlet, when the refrigerator uses the cold energy in the storage room to cool the external environment, the temperature in the storage room will not quickly exceed the preset temperature.

[0162] In the present application, the box is also configured with a refrigeration fan, which is arranged in the box. The controller controls the opening of the air inlet and controls the operation of the refrigeration fan. After the fourth preset time, the air supply fan is controlled to operate so as to blow the cold in the storage room from the air outlet to the outside of the box through the air supply channel to cool the external environment.

[0163] The embodiment of the present application does not specifically limit the fourth preset time length.

[0164] In this way, when the air inlet is opened, the refrigeration fan is controlled to operate at the same time, and the operation of the refrigeration fan can make the coldness in the storage room more uniform, which is conducive to the coldness to be discharged from the air inlet. After the fourth preset time, the air supply fan is turned on again, and the air supply channel is filled with cold air. The air supply fan can blow the cold air in the air supply channel to the external environment.

[0165] When the refrigerator is cooling the external environment, the circulation path of the cold air in the storage room can be seen from Figure 4 shown.

[0166] It can be seen that the control method of the refrigerator provided in the present application, when the refrigeration conditions are met, opens the air inlet between the storage chamber and the air supply channel, and controls the operation of the air supply fan, so that the cold air in the storage chamber can enter the air supply channel through the air inlet, and the air supply fan blows the cold air in the air supply channel to the external environment, thereby achieving the effect of cooling the external environment.

[0167] In the present application, when the controller receives the third instruction to turn off the cooling mode, or the running time of the cooling mode reaches the fifth preset time, the air inlet is controlled to be closed. After the sixth preset time, the air supply fan is controlled to stop running, and the refrigeration fan and the compressor are controlled to continue running. After the seventh preset time, the refrigeration fan and the compressor are controlled according to the temperature in the storage room and the preset temperature.

[0168] The third instruction may be generated by the following two possible implementations:

[0169] In a possible implementation, the third instruction is generated by the controller based on the detected temperature of the external environment. Specifically, when the controller detects that the external environment temperature drops to a certain value, the third instruction is generated. For example, when the controller detects that the external environment drops to 27°C, the third instruction is generated.

[0170] In another possible implementation, the third instruction is generated when the user chooses to turn off the refrigeration mode through a physical button on the refrigerator or a button on the refrigerator display.

[0171] The fifth preset duration may be 1 hour or 2 hours, and may be set by the user or by default, which is not limited in the embodiment of the present application.

[0172] The sixth preset duration may be 10 seconds or 20 seconds, which is not limited in the embodiment of the present application.

[0173] The seventh preset duration may be 10 seconds or 20 seconds, which is not limited in the embodiment of the present application.

[0174] In this way, the cooling mode can be turned off based on the user's instructions or the operating time, which can reduce the significant impact of the long-term cooling mode on the temperature in the refrigerator storage room. When the cooling mode is turned off, the air inlet is first closed, and then the air supply fan is turned off after a period of time, so that the air supply fan can blow the cold air remaining in the air supply channel to the external environment. The refrigeration fan and the compressor are controlled to run continuously for a period of time, so that the temperature in the storage room is reduced and the temperature in the storage room is kept relatively uniform.

[0175] Below, taking specific duration and temperature as an example, the control method of using a refrigerator to cool the external environment of the present application is described in detail.

[0176] Figure 7 The present invention is a flow chart of a control method for cooling an external environment using a refrigerator according to some embodiments.

[0177] like Figure 7 As shown, the control method for using a refrigerator to cool the external environment includes the following steps:

[0178] S701, start cooling mode.

[0179] When an instruction to start the cooling mode is received, such as the first instruction described in the above embodiment, the cooling mode can be started.

[0180] S702: Are all cooling conditions met?

[0181] The cooling conditions include the above four conditions, and it is determined whether the four conditions described in the above embodiment are all satisfied. If all are satisfied, the following step S703 is executed, and if not, the above step S701 is executed.

[0182] S703, enter pre-cooling mode.

[0183] After entering the pre-cooling mode, the compressor is controlled to run so that the temperature in the storage room is lower than a certain preset temperature. For details, please refer to the above embodiment, which will not be repeated here.

[0184] S704: Check whether precooling is completed.

[0185] If precooling is completed, the following step S705 is executed. If precooling is not completed, step S703 is executed to continue precooling.

[0186] S705: Enter cooling operation mode.

[0187] In the cooling operation mode, the air inlet is controlled to open and the air supply fan is operated. For details, please refer to the following embodiments.

[0188] S706, the air inlet is opened, and cold air enters the air supply duct.

[0189] In this way, after pre-cooling, entering the refrigeration mode will give the refrigerator enough time to prepare, which can improve the refrigeration effect.

[0190] Next, a control method for a refrigerator to enter a cooling mode and exit a cooling mode is described. Figure 8 The present invention is a flow chart of a method for controlling a refrigerator to enter a refrigeration mode and exit a refrigeration mode according to some embodiments.

[0191] like Figure 8 As shown, the control method for the refrigerator to enter the refrigeration mode and exit the refrigeration mode includes the following steps:

[0192] S801, enter cooling mode.

[0193] S802, open the air inlet.

[0194] S803, refrigeration fans and compressors are operating normally.

[0195] S804: Whether the air inlet opening time is greater than or equal to 10 seconds.

[0196] 10 seconds corresponds to the fourth preset time length in the above embodiment. The embodiment of the present application is only illustrated by taking 10 seconds as an example and does not constitute any limitation.

[0197] If the air inlet opening time is greater than or equal to 10 seconds, the following step S805 is executed, otherwise, step S803 is continued.

[0198] S805, the air supply fan starts running.

[0199] S806: Whether the user turns off the cooling mode or the cooling mode runs for more than or equal to 1 hour.

[0200] 1 hour corresponds to the fifth preset time length in the above embodiment. The embodiment of the present application is only illustrated by taking 1 hour as an example and does not constitute any limitation.

[0201] If the user turns off the cooling mode or the cooling mode is running for more than or equal to 1 hour, the following step S807 is executed; otherwise, the following step S805 is continued.

[0202] S807, close the air inlet.

[0203] S808: Whether the air inlet closing time is greater than or equal to 10 seconds.

[0204] 10 seconds corresponds to the sixth preset time length in the above embodiment. The embodiment of the present application is only illustrated by taking 10 seconds as an example and does not constitute any limitation.

[0205] If the air inlet closing time is greater than or equal to 10 seconds, the following step S809 is executed, otherwise, step S807 is continued.

[0206] S809. Turn off the air supply fan.

[0207] S8010, the refrigeration fan and compressor will operate normally for 10 seconds and then operate normally according to the gear setting.

[0208] 10 seconds corresponds to the seventh preset time length in the above embodiment. The embodiment of the present application is only illustrated by taking 10 seconds as an example and does not constitute any limitation.

[0209] Normal operation is performed according to the gear setting, that is, the refrigeration fan and the compressor are controlled to operate according to the preset temperature corresponding to the gear setting. For details, please refer to the above embodiment, which will not be repeated here.

[0210] S8011, cooling mode ends.

[0211] In this way, it is possible to use the refrigerator to cool the external environment, for example, to use the refrigerator to cool the kitchen.

[0212] Combined with the above Figure 2 The structure shown in the figure illustrates the control method of the controller controlling the refrigerator to heat the external environment. For details, please refer to Fig. 9 shown. Fig. 9 The figure is a flow chart of a method for controlling a refrigerator according to some embodiments.

[0213] Fig. 9 As shown, the refrigerator control method may include the following steps:

[0214] S901. When a second instruction to start a heating mode is received, determine whether a heating condition is met.

[0215] The second instruction may be generated by the following two possible implementations:

[0216] In a possible implementation, the second instruction is generated by the controller based on the detected temperature of the external environment. Specifically, when the controller detects that the external environment temperature is lower than a certain value, the second instruction is generated. For example, when the controller detects that the external environment temperature is lower than 15°C, the second instruction is generated.

[0217] In another possible implementation, the second instruction is generated when the user chooses to turn on the heating mode through a physical button on the refrigerator or a button on the refrigerator display.

[0218] In this application, the heating condition includes at least one of the following four heating conditions:

[0219] Heating condition one: the time interval between the current moment and the last time the heating mode ended is greater than or equal to the eighth preset time length.

[0220] The eighth preset time length may be 6 hours or 7 hours, and this embodiment of the present application does not specifically limit this.

[0221] In this way, since the heating mode requires the participation of the second condenser, the temperature in the refrigerator will drop faster. If the heating mode is frequently turned on, the refrigerator may be over-refrigerated. By controlling the interval between two heating modes, it is possible to reduce the situation where the refrigerator is over-refrigerated due to frequent activation of the heating mode, which may affect the food in the refrigerator.

[0222] Heating condition two: within a ninth preset time period before the current moment, the startup rate of the compressor is greater than or equal to a second preset startup rate.

[0223] The ninth preset duration may be 24 hours or 12 hours, which is not limited in the embodiment of the present application. The second preset startup rate may be 85% or 90%, which is not limited in the embodiment of the present application.

[0224] When the power-on rate is greater than the second preset power-on rate, it means that the refrigerator may be overloaded due to opening and closing the door, putting in food, high ambient temperature, etc., the temperature of the compressor is high, and the heat dissipation demand is large. At this time, turning on the heating mode will help dissipate heat for the compressor and improve the user's heating experience.

[0225] Heating condition three: within the tenth preset time period before the current moment, the door of the refrigerator is opened at least once.

[0226] The tenth preset time length can be 3 hours or 4 hours, which can be set according to the actual situation of the refrigerator. The embodiment of the present application does not limit the third preset time length.

[0227] In this way, since opening and closing the refrigerator door may cause the temperature of the storage room to rise, the startup efficiency of the compressor is higher at this time and the compressor's heat dissipation demand is greater. Therefore, turning on the heating mode when there is a door opening and closing operation for a period of time will help dissipate heat for the compressor and improve the user's heating experience.

[0228] Heating condition four: the ambient temperature is less than or equal to the second preset temperature.

[0229] In this way, the heating mode is turned on only when the ambient temperature is low, and the user's perception of heat is more obvious, which can improve the user experience. In addition, it can avoid the situation where the user accidentally touches the heating mode when the ambient temperature is high.

[0230] S902. If the heating conditions are met, the switch element is controlled to be in the second state so that refrigerant flows through the second condenser to provide heat for the air supply channel; and the air inlet is closed, and the air supply fan is controlled to blow the heat in the air supply channel to the outside of the box through the air outlet to heat the external environment.

[0231] By controlling the switch element to be in the second state, the refrigerant flows through the compressor, the first condenser, the second condenser, the capillary tube and the evaporator in sequence, so that the evaporator provides cold air for the storage room and the second condenser provides heat for the air supply channel.

[0232] In the present application, if the heating conditions are met, the controller controls the defrost mode. After the defrost is completed, the switch element is controlled to be in the second state so that the refrigerant flows through the compressor, the first condenser, the second condenser, the capillary tube and the evaporator in sequence, so that the evaporator provides cooling for the storage room and the second condenser provides heat for the air supply channel.

[0233] When the switch element is in the second state, refrigerant flows through the second condenser. At this time, the flow direction of the refrigerant in the first condenser and the second condenser can be referred to the above Figure 5 At this time, the heat emitted by the second condenser will enter the air supply channel.

[0234] The defrost mode is to melt the frost on the evaporator. After entering the cooling mode, the first condenser and the second condenser work at the same time, and the compressor needs to run at a high intensity to generate enough heat. The greater the working intensity of the compressor, the higher the evaporator needs to work, which will cause more frost to condense on the evaporator. Therefore, before entering the heating mode, the defrost mode is executed first, so that the frost on the evaporator during the heating process of the refrigerator will not be too much to affect the normal operation of the refrigerator.

[0235] In the present application, after the controller controls the switch element to be in the second state, the air inlet can be closed, the refrigeration fan can be controlled to run, and the compressor can be controlled to run at a speed higher than the target speed. After the eleventh preset time period, the air supply fan is controlled to blow the heat in the air supply channel to the outside of the box through the air outlet to heat the external environment.

[0236] The embodiment of the present application does not specifically limit the eleventh preset time length.

[0237] In this way, the air inlet is in a closed state, and the cold air in the storage room will not be blown out. The refrigeration fan is controlled to operate, and the operation of the refrigeration fan can make the cooling amount in the storage room more uniform. After the eleventh preset time, the air supply fan is turned on again. At this time, the air supply channel is full of hot air, and the air supply fan can blow the hot air in the air supply channel to the external environment.

[0238] When the refrigerator heats the external environment, the circulation path of the hot air in the storage room can be seen in Figure 5 shown.

[0239] It can be seen that the control method of the refrigerator provided by the present application, when the heating conditions are met, controls the switch element to be in the second state, so that refrigerant flows through the second condenser, and the second condenser can work to dissipate heat. After a period of time, the air supply fan is controlled to operate so that the heat dissipated by the second condenser fills the air supply channel, and the air supply fan blows the heat in the air supply channel to the external environment, avoiding the situation where the temperature of the hot air blown out is low, so as to achieve the effect of heating the external environment.

[0240] In the present application, when the fourth instruction to turn off the heating mode is received, or the operation time of the heating mode reaches the twelfth preset time, the control switch element is switched from the second state to the first state. After the thirteenth preset time, the air supply fan is controlled to stop running, and the refrigeration fan and the compressor are controlled to continue running. After the fourteenth preset time, the refrigeration fan and the compressor are controlled according to the temperature in the storage room and the preset temperature.

[0241] The fourth instruction may be generated by the following two possible implementations:

[0242] In a possible implementation, the fourth instruction is generated by the controller based on the detected temperature of the external environment. Specifically, when the controller detects that the temperature of the external environment rises to a certain value, the fourth instruction is generated. For example, when the controller detects that the temperature of the external environment rises to 26°C, the fourth instruction is generated.

[0243] In another possible implementation, the fourth instruction is generated when the user chooses to turn off the heating mode through a physical button on the refrigerator or a button on the refrigerator display.

[0244] The twelfth preset time length can be 1 hour or 2 hours. It can be set by the user or by default. The embodiment of the present application does not limit this.

[0245] The thirteenth preset time length can be 10 seconds or 20 seconds, which is not limited in the embodiment of the present application.

[0246] The fourteenth preset time length can be 10 seconds or 20 seconds, which is not limited in the embodiment of the present application.

[0247] In this way, by turning off the heating mode based on the user's instructions or the operating time, it is possible to reduce the situation where the compressor runs at high speed for a long time due to the heating mode being turned on for a long time, causing the over-refrigeration. When turning off the heating mode, the switch element is first controlled to switch to the first state, and then the air supply fan is turned off after a period of time, so that the air supply fan can blow the hot air remaining in the air supply channel to the external environment to avoid heat remaining in the air supply channel. The refrigeration fan and the compressor are controlled to run continuously for a period of time, so that the temperature in the storage room meets the set temperature and the temperature in the storage room is kept relatively uniform.

[0248] Below, taking specific duration and temperature as an example, the control method of using a refrigerator to heat the external environment of the present application is described in detail.

[0249] Fig.10 1 is a flow chart of a control method for heating an external environment using a refrigerator according to some embodiments.

[0250] like Fig.10 As shown, the control method for using a refrigerator to heat the external environment includes the following steps:

[0251] S1001, turn on heating mode.

[0252] When an instruction to start the heating mode is received, such as the second instruction described in the above embodiment, the heating mode can be started.

[0253] S1002: Are all heating conditions met?

[0254] The heating conditions include the above four conditions, and it is determined whether the four conditions described in the above embodiment are all satisfied. If all are satisfied, the following step S1003 is executed, and if not, the above step S1001 is executed.

[0255] S1003, enter defrost mode.

[0256] S1004: Check whether defrosting is completed.

[0257] If defrosting is completed, the following step S1005 is executed. If defrosting is not completed, step S1003 is executed to continue preheating.

[0258] S1005, entering heating operation mode.

[0259] In the heating operation mode, the air inlet is controlled to be closed, the one-way two-way solenoid valve is in the second state, and the air supply fan is working. For details, please refer to the following embodiment.

[0260] S1006, the one-way two-way solenoid valve is switched to the second condenser, the second condenser starts to work, and the hot air enters the air supply channel.

[0261] The one-way two-way solenoid valve is switched to the second condenser, that is, the one-way two-way solenoid valve described in the above embodiment is in the second state.

[0262] In this way, after defrosting, entering the heating mode can reduce the situation where the refrigerator cannot operate normally due to excessive frost on the evaporator in the heating mode.

[0263] Next, taking a switch element being a one-way two-way solenoid valve as an example, a control method for a refrigerator to enter a heating mode and exit a heating mode is described. Fig.11 The present invention is a flow chart of a method for controlling a refrigerator to enter a heating mode and exit a heating mode according to some embodiments.

[0264] like Fig.11 As shown, the control method for the refrigerator to enter the heating mode and exit the heating mode includes the following steps:

[0265] S1101, enter heating mode.

[0266] S1102, the one-way two-way solenoid valve is switched to the second condenser.

[0267] After the one-way two-way solenoid valve is switched to the second condenser, the second condenser starts to work, and refrigerant flows through it, and the second condenser will emit heat when it works.

[0268] S1103, refrigeration fan and compressor run at high speed.

[0269] By controlling the refrigeration fan and the compressor to run at high speed, the heat dissipation demand of the compressor is high, which is beneficial for heating the external environment.

[0270] S1104: Is the switching time of the one-way two-way solenoid valve greater than or equal to 10 seconds?

[0271] 10 seconds corresponds to the eleventh preset time length in the above embodiment. The embodiment of the present application is only illustrated by taking 10 seconds as an example and does not constitute any limitation.

[0272] If the switching time of the one-way two-way solenoid valve is greater than or equal to 10 seconds, execute the following step S1105, otherwise, continue to execute step S1103.

[0273] S1105, the air supply fan is started and operated.

[0274] S1106: Whether the user turns off the heating mode or the heating mode is running for more than or equal to 1 hour.

[0275] 1 hour corresponds to the twelfth preset time length in the above embodiment. The embodiment of the present application is only illustrated by taking 1 hour as an example and does not constitute any limitation.

[0276] If the user turns off the heating mode or the heating mode is running for more than or equal to 1 hour, the following step S1107 is executed; otherwise, the following step S1105 is continued.

[0277] S1107, the one-way two-way solenoid valve is switched to the first condenser.

[0278] After the one-way two-way solenoid valve is switched to the first condenser, no refrigerant flows through the second condenser and the second condenser does not work.

[0279] S11011. Is the switching time of the one-way two-way solenoid valve greater than or equal to 10 seconds?

[0280] 10 seconds corresponds to the thirteenth preset time length in the above embodiment. The embodiment of the present application is only illustrated by taking 10 seconds as an example and does not constitute any limitation.

[0281] If the switching time of the one-way two-way solenoid valve is greater than or equal to 10 seconds, execute the following step S1109, otherwise, continue to execute step S1107.

[0282] S1109. Turn off the air supply fan.

[0283] S1110, after the refrigeration fan and compressor operate normally for 10 seconds, they operate normally according to the gear setting.

[0284] 10 seconds corresponds to the fourteenth preset time length in the above embodiment. The embodiment of the present application is only illustrated by taking 10 seconds as an example and does not constitute any limitation.

[0285] Normal operation is performed according to the gear setting, that is, the refrigeration fan and the compressor are controlled to operate according to the preset temperature corresponding to the gear setting. For details, please refer to the above embodiment, which will not be repeated here.

[0286] S1111, heating mode ends.

[0287] In this way, it is possible to use the refrigerator to heat the external environment, for example, to use the refrigerator to heat the kitchen.

[0288] The present application also provides a computer-readable storage medium, which may include: a USB flash drive, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a disk or an optical disk, and other media that can store program codes.
