[0036] Food requires appropriate humidity for categorized storage and preservation. Humidity control technology is a crucial component of refrigerator preservation. With the development of refrigerator technology, refrigeration, variable temperature storage, and freezing have become important storage methods. Variable temperature storage typically involves designating a specific area within the refrigerator compartment as a variable temperature zone or temperature control area (hereinafter referred to as the variable temperature zone). During long-term use, the variable temperature zone can easily remain in an environment with extremely high humidity, such as 100%. Under such conditions, food is prone to spoilage due to excessive humidity. Therefore, this application provides a refrigerator, a humidity control method, a device, and a storage medium, which will be described in detail below.

[0037] The refrigerator in this embodiment has a refrigerator compartment and a variable temperature compartment; a variable temperature damper is provided between the refrigerator compartment and the variable temperature compartment, and the damper has a first state of opening the refrigerator compartment and the variable temperature compartment and a second state of cutting off the refrigerator compartment and the variable temperature compartment. The refrigerator also includes a controller for executing the humidity regulation control method provided in this embodiment. Figure 1 As shown, the humidity control method includes:

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

[0039] S202, when the variable temperature humidity is higher than the first preset humidity value, the variable temperature damper is controlled to be in the first state; when the variable temperature humidity is lower than the second preset humidity value, the variable temperature damper is controlled 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 this application embodiment, when the temperature and humidity of the variable temperature chamber exceed 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, thereby reducing the humidity in the variable temperature chamber; when the temperature and humidity of the variable temperature chamber are lower than a second preset humidity value, when the temperature and humidity in the variable temperature chamber drop 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 too much loss of humid air in the variable temperature chamber; thereby, the humidity of the variable temperature chamber is kept within a suitable humidity range, which is conducive to food storage in the variable temperature chamber, reducing food spoilage or slowing down food spoilage.

[0041] In this 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 humidity compartment. For example, the user can set the humidity value via an app or the refrigerator panel based on the type of food and a recommended range; alternatively, the refrigerator can identify the food, determine its type, and then set the first or 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 inside the refrigerator compartment fluctuates periodically. During refrigerator operation, as the refrigerator cools, moisture inside condenses on the evaporator surface with the airflow, causing a rapid drop in humidity. When cooling stops, the humidity rises again. Therefore, the humidity inside the refrigerator fluctuates periodically with the cooling cycle. For this reason, as an optional implementation of the above embodiment, before controlling the temperature-controlled damper to be in the first state when the variable temperature humidity is higher than a first preset humidity value, and before controlling the temperature-controlled damper to be in the second state when the variable temperature humidity is lower than a second preset humidity value, such as... Figure 2 As shown, the control method further includes:

[0043] S101, obtain the refrigeration temperature of the refrigerator compartment;

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

[0045] In this embodiment, the humid air in the variable temperature compartment is introduced into the refrigerator compartment after the refrigeration process in the refrigerator compartment has finished. Once the refrigerator temperature reaches the shutdown point, the compressor stops supplying cooling to the refrigerator evaporator, and the refrigeration process ends. During refrigeration, the humid air in the refrigerator compartment condenses on the surface of the refrigerator evaporator, resulting in a lower humidity environment inside the refrigerator compartment. At this time, the refrigerator fan operates at a first speed, causing the frost layer inside the refrigerator evaporator to defrost and increasing the humidity inside the refrigerator compartment. If the humidity at this time is higher than a first preset humidity value, the variable temperature damper is in its first state. While the refrigerator fan increases the humidity inside the refrigerator compartment, the humid air in the variable temperature compartment also enters the refrigerator compartment to humidify it. This allows the refrigerator compartment to maintain a relatively high humidity for a longer period and the variable temperature compartment to remain within a suitable humidity range.

[0046] Compared to keeping the variable-temperature damper in its first position during refrigeration, keeping it in the first position slows down the rate of humidity decrease in the variable-temperature compartment. During refrigeration, the evaporator surface temperature drops as the compressor cools. If the damper is in its first position at this time, the humid air entering the refrigerator compartment from the variable-temperature compartment will gradually condense on the evaporator surface, causing the humidity in the variable-temperature compartment to drop rapidly. This is less conducive to preserving freshness compared to keeping the damper in its first position after refrigeration is complete. However, after refrigeration, the evaporator surface temperature rises as the compressor stops cooling. If the damper is in its first position at this time, the humid air entering the refrigerator compartment from the variable-temperature compartment will increase the humidity in the refrigerator compartment instead of gradually condensing on the surface. This slows down the rate of humidity decrease in the variable-temperature compartment and is beneficial for preserving freshness.

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

[0048] S301, Obtain the defrosting temperature for indicating the defrosting of the refrigeration evaporator; the refrigeration evaporator is used to supply cooling to the refrigerator compartment;

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

[0050] In this embodiment, when humid air from the variable temperature compartment is introduced into the refrigerator compartment, the surface temperature of the refrigerator evaporator continuously rises because the refrigerator stops supplying cooling to the refrigerator compartment. When the defrosting temperature is higher than the first preset temperature value, the refrigerator fan is controlled to stop running, and the refrigerator evaporator and the air no longer exchange heat, so that the temperature of the refrigerator compartment is maintained at a low temperature for a period of time, allowing the refrigerator compartment to maintain a higher humidity and lower humidity for a longer period of time during the non-cooling stage.

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

[0052] As an optional implementation of the above embodiments, after controlling the refrigeration fan to stop running when the defrosting temperature is higher than the first preset temperature value, such as... Figure 4 As shown, the control method further includes:

[0053] S401, when the refrigeration temperature is higher than the start-up temperature, control the compressor to supply cooling to the refrigeration evaporator and control the refrigeration fan to run at the second speed until the refrigeration temperature reaches the stop-up temperature.

[0054] In this embodiment, when the defrosting temperature is higher than the first preset temperature value, the refrigeration fan is controlled to stop running, and the heat exchange between the refrigeration evaporator and the air ceases, so that the temperature of the refrigerator compartment is maintained at a low temperature for a period of time until the refrigeration temperature rises to the start-up temperature. At this point, the compressor is controlled to start supplying cooling to the refrigeration evaporator, and the refrigeration fan is controlled to run at the second speed to reduce the temperature inside the refrigerator compartment until the refrigeration temperature reaches the stop-up temperature, thus completing one refrigeration cycle of the refrigerator compartment.

[0055] As an optional implementation of the above embodiments, the second rotational speed is less than the first rotational speed. In this embodiment, when the refrigerator provides cooling to the refrigerator compartment, the refrigeration fan operates at the second rotational speed; when the refrigerator stops providing cooling to the refrigerator compartment until the defrost temperature is higher than the first preset temperature value, the fan speed of the refrigeration fan increases from the second rotational speed to the first rotational speed, so that the humidity in the refrigerator compartment can be quickly increased, reducing the time the refrigerator compartment operates at low humidity, which is beneficial to increasing the operating time of the refrigerator compartment in a high humidity environment and achieving the high humidity operation index of the refrigerator.

[0056] As an optional implementation of the above embodiments, before controlling the refrigeration fan to stop operating when the defrosting temperature is higher than the first preset temperature value; such as Figure 5 As shown, the control method further includes:

[0057] S302, when the defrosting temperature is higher than the second preset temperature value, control the refrigeration fan to run at a third speed; wherein the second preset temperature value is less than the first preset temperature value, and the third speed is less than the first speed.

[0058] In this embodiment, after the compressor stops supplying cooling to the refrigeration fan, the surface temperature of the refrigeration evaporator continuously increases as the refrigeration fan operates at a higher speed, i.e., the defrosting temperature continuously increases. When it reaches the second preset temperature value, the surface temperature of the refrigeration evaporator rises to a certain temperature condition. At this time, the temperature inside the refrigerator compartment also rises. Therefore, to prevent the refrigerator compartment temperature from rising too quickly and reaching the compressor start-up condition rapidly, the speed of the refrigeration fan is reduced to a third speed when the defrosting temperature is higher than the second preset temperature value, so that the temperature inside the refrigerator compartment rises slowly. At the same time, the humidity inside the refrigerator compartment also increases to a higher humidity level. The slow rise in temperature inside the refrigerator compartment can prolong the time to reach the temperature and start up, which is beneficial to increasing the operating time of the refrigerator compartment in a high humidity environment and achieving the high humidity operation index of the refrigerator.

[0059] In this embodiment, the second preset temperature value is set to -1℃ to 0℃. For example, the second preset temperature value is 0℃. When the defrosting temperature rises to 0℃, the frost layer on the evaporator surface melts, and the temperature rise rate of the refrigerator compartment increases rapidly. At this time, by reducing the speed of the refrigerator fan, the temperature rise rate of the refrigerator compartment is slowed down.

[0060] As an optional implementation of the above embodiments, the refrigerator is a dual-system refrigerator; when the compressor stops supplying cooling to the refrigeration evaporator, the compressor supplies cooling to the freezing evaporator, or the compressor stops operating. In this embodiment, the refrigerator is a dual-system refrigerator, which further includes a freezing evaporator. Figure 6 The diagram illustrates a refrigerant circulation system for a dual-system refrigerator. This system includes a refrigerator evaporator 7, a freezer 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 sequentially to the refrigerator evaporator 7 and the freezer evaporator 8 via the first capillary tube 6. The second outlet is connected to the freezer evaporator 8 via the second capillary tube 5. The outlet of the freezer evaporator 8 is connected to the inlet of the compressor 1.

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

[0062] The solenoid valve has a first state and a second state. In the first state, the solenoid valve's inlet is connected to the second outlet, meaning the refrigerant flows through the solenoid valve, the second capillary tube, and the refrigeration evaporator. In this state, the compressor only supplies cooling to the refrigeration evaporator. In the second state, the solenoid valve's inlet is connected to the first outlet, meaning the refrigerant flows through the solenoid valve, the first capillary tube, the refrigeration evaporator, and the refrigeration evaporator. In this state, the compressor supplies cooling to both the refrigeration and refrigeration evaporators.

[0063] In one embodiment, when the compressor stops supplying cooling to the refrigeration evaporator, the solenoid valve is in the first state, at which time the compressor only supplies cooling to the freezing evaporator; when the refrigeration temperature is higher than the start-up temperature, the compressor is controlled to supply cooling to the refrigeration evaporator and the refrigeration fan is controlled to run at a second speed, the solenoid valve is controlled to be in the second state, at which time the compressor supplies cooling to both the refrigeration evaporator and the freezing evaporator. In some embodiments, when the compressor stops supplying cooling to the refrigeration evaporator, the compressor may also be in a stopped state when the freezing conditions in the freezer compartment are met.

[0064] In the technical solution of this application embodiment, after the refrigeration of the refrigerator compartment is completed, the dual-system refrigerator enters the defrosting and humidification stage, which enables the dual-system refrigerator to maintain the refrigerator compartment in a high humidity environment for a long time, and reduces the impact on the temperature of the freezer compartment, improves the humidification effect of the refrigerator compartment and the food preservation effect of the freezer compartment; and through the defrosting and humidification stage, the humidification of the refrigerator compartment can be improved by dehumidifying the variable temperature compartment, and by utilizing the air convection between the two compartments, the humidity of the variable temperature compartment is prevented from always being as high as 100%, which is more conducive to the storage and placement of food such as vegetables in the variable temperature space, and helps to improve the humidity of the refrigerator compartment.

[0065] To better implement the humidity control method in the embodiments of this application, based on the humidity control method, the embodiments of this application also provide a humidity control device, such as... Figure 7 As shown, the humidity control device includes:
