The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.

[0036] Appropriate humidity is required for food classification, storage and preservation. Moisturizing technology is an important part of refrigerator preservation. With the development of refrigerator technology, refrigerated storage, variable temperature storage and frozen storage are important storage parts of refrigerator preservation. Variable temperature storage generally divides an area in the refrigerator as a variable temperature zone or variable temperature chamber (the variable temperature chamber is taken as an example below). During long-term use, the variable temperature chamber is prone to being in an ultra-high humidity environment for a long time, such as 100%; in this case, the food is prone to rot and deterioration due to excessive humidity. To this end, the embodiments of the present application provide a refrigerator, a control method, a device and a storage medium for humidity regulation, which are described in detail below.

[0037] The refrigerator in the embodiment of the present application has a refrigerating chamber and a temperature-changing chamber; a temperature-changing air door is provided between the refrigerating chamber and the temperature-changing chamber, and the temperature-changing air door has a first state of connecting the refrigerating chamber and the temperature-changing chamber and a second state of disconnecting the refrigerating chamber and the temperature-changing chamber. The refrigerator also includes a controller for executing the humidity control method provided in the embodiment of the present application. Figure 1 As shown, the humidity adjustment control method includes:

[0038] S201, obtaining the variable temperature and humidity of the variable temperature chamber;

[0039] S202, when the variable temperature and humidity are higher than the first preset humidity value, control the variable temperature damper to be in the first state; when the variable temperature and humidity are lower than the second preset humidity value, control the variable temperature damper to be in the second state; the second preset humidity value is less than the first preset humidity value.

[0040] In the technical solution of the embodiment of the present application, when the variable temperature and humidity of the variable temperature chamber exceeds a first preset humidity value, the variable temperature damper is controlled to be in a first state, so that the variable temperature chamber and the cold storage chamber are connected, and the air flows to reduce the humidity in the variable temperature chamber; when the variable temperature and humidity of the variable temperature chamber is lower than a second preset humidity value, when the variable temperature and humidity in the variable temperature chamber drops to a preset level, the variable temperature damper is controlled to be in a second state, so that the variable temperature chamber and the cold storage chamber are cut off, and the air does not flow, so as to avoid excessive loss of humid air in the variable temperature chamber; and then the humidity in the variable temperature chamber is within an appropriate humidity range, so as to facilitate the storage of food in the variable temperature chamber and reduce or slow down food rot and deterioration.

[0041] In an embodiment, the first preset humidity value and the second preset humidity value can be set according to the type of food stored in the variable temperature chamber. For example, the user can set it through the APP or the refrigerator panel according to the food type and the recommended range; or the refrigerator can identify the food, determine the food type, and then set the first preset humidity value or the second preset humidity value. In some embodiments, the first preset humidity value is set between 99% and 100%, and the second preset humidity value is set between 94% and 95%.

[0042] In a refrigerator, the humidity in the cold storage room fluctuates periodically. When the refrigerator is in operation, during the refrigeration process of the cold storage room, the moisture in the box condenses onto the surface of the evaporator as the wind circulates, and then the humidity in the box drops rapidly. When the refrigeration stops, the humidity in the box will rise again. Therefore, the humidity in the box also fluctuates periodically during the refrigeration cycle. For this reason, as an optional implementation of the above embodiment, when the variable temperature and humidity are higher than the first preset humidity value, the variable temperature damper is controlled to be in the first state; when the variable temperature and humidity are lower than the second preset humidity value, the variable temperature damper is controlled to be in the second state, as before. Figure 2 As shown, the control method also includes:

[0043] S101, obtaining the refrigeration temperature of the refrigeration chamber;

[0044] S102, when the refrigeration temperature reaches the shutdown point temperature, controlling the compressor to stop supplying cold to the refrigeration evaporator and controlling the refrigeration fan to run at a first speed.

[0045] In this embodiment, the humid air in the variable temperature chamber is introduced into the refrigerated room after the refrigeration in the refrigerated room is finished. After the refrigerated temperature reaches the shutdown point temperature, the compressor stops supplying cold to the refrigerated evaporator, and the refrigerated room ends refrigeration. During refrigeration, the humid air in the refrigerated room condenses on the surface of the refrigerated evaporator, and the refrigerated room is in a relatively low humidity environment; at this time, the refrigerated fan runs at a first speed, so that the frost layer in the refrigerated evaporator thaws and the humidity in the refrigerated room is increased; if at this time, the variable temperature humidity is higher than the first preset humidity value, the variable temperature damper is in the first state, and while the refrigerated fan causes the humidity in the refrigerated room to increase, the humid air in the variable temperature chamber will also enter the refrigerated room to humidify the refrigerated room; in this way, the refrigerated room can maintain a relatively high humidity for a long time and the variable temperature chamber is within a suitable humidity range.

[0046] Compared with controlling the variable temperature damper in the first state during refrigeration, the rate of decrease of humidity in the variable temperature room can be slowed down. During refrigeration, the temperature of the evaporator surface decreases because the compressor is in the cooling stage. At this time, the variable temperature damper is in the first state, and the humid air entering the cold storage room from the variable temperature room will gradually condense on the evaporator surface, which will cause the air humidity in the variable temperature room to drop rapidly, which is not conducive to fresh-keeping compared to controlling the variable temperature damper in the first state after refrigeration is completed. After refrigeration, the temperature of the evaporator surface rises because the compressor is in the stage of stopping cooling. At this time, the variable temperature damper is in the first state, and the humid air entering the cold storage room from the variable temperature room increases the humidity in the cold storage room, and will not gradually condense on the surface, which will slow down the rate of decrease of air humidity in the variable temperature room, which is conducive to fresh-keeping.

[0047] As an optional implementation of the above embodiment, when the variable temperature and humidity are higher than the first preset humidity value, the variable temperature damper is controlled to be in the first state; when the variable temperature and humidity are lower than the second preset humidity value, the variable temperature damper is controlled to be in the second state. Figure 3 As shown, the control method also includes:

[0048] S301, obtaining a defrosting temperature for indicating defrosting of a refrigeration evaporator; the refrigeration evaporator is used to supply cold air to a refrigeration chamber;

[0049] S303, when the defrost temperature is higher than a first preset temperature value, controlling the refrigeration fan to stop running.

[0050] In this embodiment, when the humid air in the variable temperature room is introduced into the cold storage room, the surface temperature of the cold storage evaporator continues to rise because the refrigerator stops supplying cold to the cold storage room. When the defrost temperature is higher than the first preset temperature value, the cold storage fan is controlled to stop running, and there is no heat exchange between the cold storage evaporator and the air, so that the temperature of the cold storage room is maintained at a lower temperature for a period of time, so that the cold storage room can maintain a higher humidity and a lower humidity for a longer time in the non-refrigeration stage.

[0051] In some embodiments, the first preset temperature value is set to 3-4°C.

[0052] As an optional implementation of the above embodiment, when the defrosting temperature is higher than the first preset temperature value, after the refrigeration fan is controlled to stop running, Figure 4 As shown, the control method also includes:

[0053] S401, when the refrigeration temperature is greater than the start-up point temperature, controlling the compressor to supply cold air to the refrigeration evaporator and controlling the refrigeration fan to operate at a second speed until the refrigeration temperature reaches the shutdown point temperature.

[0054] In this embodiment, when the defrost temperature is higher than the first preset temperature value, the refrigeration fan is controlled to stop running, and there is no heat exchange between the refrigeration evaporator and the air, so that the temperature of the refrigeration chamber is maintained at a relatively low temperature for a period of time until the refrigeration temperature is increased to the start-up point temperature. Here, the compressor is controlled to start supplying cold to the refrigeration evaporator, and the refrigeration fan is controlled to run at a second speed to lower the temperature in the refrigeration chamber until the refrigeration temperature reaches the stop point temperature, thereby completing a refrigeration cycle of the refrigeration chamber.

[0055] As an optional implementation of the above embodiment, the second speed is less than the first speed. In the embodiment, when the refrigerator provides cold air to the refrigerating chamber, the refrigerating fan runs at the second speed; when the refrigerator stops providing cold air to the refrigerating chamber until the defrosting temperature is higher than the first preset temperature value, the wind speed of the refrigerating fan is increased from the second speed to the first speed, so that the humidity in the refrigerating chamber can be quickly increased, reducing the time when the refrigerating chamber runs at a lower humidity, which is conducive to increasing the operation time of the refrigerating chamber in a high humidity environment, and achieving the high humidity operation index of the refrigerator.

[0056] As an optional implementation of the above embodiment, when the defrost temperature is higher than the first preset temperature value, before the refrigeration fan is controlled to stop running; Figure 5 As shown, the control method also includes:

[0057] S302, when the defrost temperature is higher than a second preset temperature value, controlling the refrigeration fan to operate at a third speed; wherein the second preset temperature value is lower than the first preset temperature value, and the third speed is lower than the first speed.

[0058] In this embodiment, after the compressor stops supplying cold to the refrigeration fan, when the refrigeration fan runs at a higher wind speed, the surface temperature of the refrigeration evaporator continues to increase, that is, the defrost temperature continues to increase; when it increases to the second preset temperature value, the surface temperature of the refrigeration evaporator increases to a certain temperature condition, and the temperature in the refrigerator room is also increasing at this time. Therefore, in order to avoid the refrigerator room temperature rising too fast and quickly reaching the compressor start-up condition, when the defrost temperature is higher than the second preset temperature value, the speed of the refrigeration fan is reduced to the third speed, so that the temperature in the refrigerator room slowly increases, and at the same time the humidity in the refrigerator room also increases to a higher humidity level; the temperature in the refrigerator room slowly increases, which can extend the time to reach the temperature and start up, which is beneficial to increase the operating time of the refrigerator room in a high humidity environment and achieve the high humidity operating index of the refrigerator.

[0059] In the embodiment, the second preset temperature value is set to -1°C-0°C. For example, the second preset temperature value is 0°C. When the defrosting temperature rises to 0°C, the frost layer on the surface of the evaporator melts away, and the temperature rise speed of the refrigerating chamber becomes faster. At this time, the speed of the refrigerating fan is reduced to slow down the temperature rise speed of the refrigerating chamber.

[0060] As an optional implementation of the above embodiment, the refrigerator is a dual-system refrigerator; when the compressor stops supplying cold to the refrigerating evaporator, the compressor supplies cold to the freezing evaporator or the compressor stops running. In the embodiment, the refrigerator is a dual-system refrigerator, and the dual-system refrigerator also includes a freezing evaporator. Figure 6 As shown, a refrigerant circulation system of a dual-system refrigerator is exemplified. The refrigerant circulation system includes a refrigerating evaporator 7, a freezing evaporator 8, a compressor 1, a condenser 2, a first capillary tube 6, a second capillary tube 5 and a solenoid valve 4. The outlet of the compressor 1 is connected to the inlet of the condenser 2, and the outlet of the condenser 2 is connected to the inlet of the solenoid valve 4. The solenoid valve 4 has a first outlet and a second outlet. The first outlet is connected to the refrigerating evaporator 7 and the freezing evaporator 8 in sequence through the first capillary tube 6. The second outlet is connected to the freezing evaporator 8 through the second capillary tube 5. The outlet of the freezing evaporator 8 is connected to the inlet of the compressor 1.

[0061] In some embodiments, a drying filter 3 is further provided between the condenser and the solenoid valve.

[0062] The solenoid valve has a first state and a second state. When the solenoid valve is in the first state, the inlet of the solenoid valve is connected to the second outlet, that is, the refrigerant passes through the solenoid valve, the second capillary tube and the refrigeration evaporator, and the compressor only supplies cold to the refrigeration evaporator. When the solenoid valve is in the second state, the inlet of the solenoid valve is connected to the first outlet, that is, the refrigerant passes through the solenoid valve, the first capillary tube, the refrigeration evaporator and the refrigeration evaporator, and the compressor supplies cold to the refrigeration evaporator and the refrigeration evaporator.

[0063] In an embodiment, when the compressor stops supplying cold to the refrigerated evaporator, the solenoid valve is in a first state, and the compressor only supplies cold to the frozen evaporator; when the refrigerated temperature is greater than the start-up point temperature, the compressor is controlled to supply cold to the refrigerated evaporator and the refrigerated fan is controlled to operate at a second speed, and the solenoid valve is controlled to be in a second state, and the compressor supplies cold to the refrigerated evaporator and the frozen evaporator. In some embodiments, when the compressor stops supplying cold to the refrigerated evaporator, the compressor can also be in a stopped state when the freezer reaches a freezing condition.

[0064] In the technical solution of the embodiment of the present application, since the dual-system refrigerator enters the stage of refrigeration, defrosting and humidification after the refrigeration of the refrigerator compartment is completed, the dual-system refrigerator can maintain the refrigerator compartment in a high-humidity environment for a long time, and reduce the temperature impact on the freezer compartment, thereby improving the moisturizing effect of the refrigerator compartment and the food preservation effect in the freezer compartment; and by dehumidifying the variable temperature room during the refrigeration, defrosting and humidification stage, the humidification of the refrigerator compartment can be improved by dehumidifying the variable temperature room, and the air convection between the two compartments can be used to prevent the humidity in the variable temperature room from being as high as 100% all the time, which can be more conducive to the storage and placement of foods in the variable temperature space, such as vegetable foods, and help to increase the humidity of the refrigerator compartment.
