[0022] Before introducing the humidity control method, device, electronic device, storage medium and refrigerator provided in this application, the application scenarios involved in the various embodiments of this application will be introduced first. This application can be applied to the scenario of refrigeration equipment operation. In order to keep food fresh and meet the storage needs of different foods, the refrigeration equipment is equipped with a special storage room with adjustable humidity.

[0023] The inventors discovered that related humidification technologies typically involve setting up independent air ducts and humidity control systems within the refrigeration equipment. Airflow is controlled via independent dampers, and humidity is dynamically adjusted based on sensor feedback. Alternatively, active humidification technologies, such as integrating a condensate recovery device or a miniature humidifier into a variable-temperature drawer, maintain a high-humidity environment through evaporating condensate or ultrasonic atomization. Therefore, implementing humidification technologies in refrigeration equipment requires costly additional components, resulting in high production costs for such equipment.

[0024] To address the aforementioned technical problems, this application provides a humidity control method, device, electronic equipment, storage medium, and refrigerator. Based on the humidification or dehumidification requirements of the storage compartments, the refrigeration evaporator and each storage compartment are dynamically opened or closed, thereby achieving humidity regulation of the storage compartments. This allows for humidity regulation of the storage compartments without requiring the installation of expensive additional devices in the refrigeration equipment.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0026] The technical solutions of this application and their effects are described below through several exemplary embodiments. It should be noted that the following embodiments can be referenced, borrowed from, or combined with each other. Identical terms, similar features, and similar implementation steps in different embodiments will not be repeated.

[0027] This application provides a humidity control method applied to a refrigeration device, such as a refrigeration device. Figure 1 As shown: The refrigeration equipment 10 includes a storage compartment, a refrigerated evaporator 30, and an air duct assembly.

[0028] Specifically, the storage room provided in this application embodiment includes a first storage room 21 and at least one second storage room 22. The first storage room 21 is a storage room with adjustable humidity. The refrigeration device 10 adaptively adjusts the humidity of the first storage room 21 according to the items placed in the first storage room 21, thereby extending the storage time of the items in the first storage room 21 as much as possible. The second storage room 22 can be a cold storage room, with the temperature usually kept constant within the range set by the refrigeration device (generally 0°C to 10°C), and the humidity relatively neutral, suitable for storing most common items.

[0029] In this embodiment, the refrigerated evaporator 30 is used to generate cold energy. The refrigerated evaporator 30 generates cold energy to absorb the heat of the storage room connected to the air duct, thereby reducing the temperature and humidity of the corresponding storage room. When the refrigerated evaporator 30 is started, the water vapor in the cold air flowing through the refrigerated evaporator 30 is pre-frozen into frost, thereby forming frost on the surface of the refrigerated evaporator 30.

[0030] In this embodiment, when the refrigerated evaporator 30 is not cooling, the heat from the high-temperature cold air in the storage room is used to exchange heat with the refrigerated evaporator 30, thereby melting the frost on the refrigerated evaporator. The defrosting process is divided into the following stages: 1. The temperature of the frost layer gradually increases, but the temperature of the frost layer is ≤0℃; 2. When the surface temperature of the frost layer reaches 0℃, the frost layer melts into water, and some of the water is carried into the room by the cold air. 3. When the temperature of the frost layer rises above 0℃, it melts completely into water, and some of the water is carried into the room by the cold air.

[0031] The defrosting process of the refrigerated evaporator can increase the water content in the cold air, that is, increase the humidity, thereby increasing the humidity of the storage room.

[0032] In this embodiment, the air duct assembly includes an air duct 41 that connects the refrigerated evaporator 20 and at least two storage compartments. A fan 42 is provided inside the air duct. The air duct assembly also includes an air damper corresponding to each storage compartment. When the air damper is open, it connects the air duct 41 with the corresponding storage compartment. When it is closed, it isolates the air duct from the corresponding storage compartment.

[0033] In this embodiment, the refrigerated evaporator 30 blows cold air to each storage compartment through the air duct 41 and the fan 42. Only the storage compartment with the air duct open can receive the cold air blown from the refrigerated evaporator 30. For the storage compartment with the air duct closed, the air duct is isolated from the storage compartment, that is, it cannot receive the cold air blown from the refrigerated evaporator 30.

[0034] In one example, the refrigerated evaporator 30 is started, the damper of the first storage compartment 21 is opened, and the damper of the second storage compartment 22 is closed. The refrigerated evaporator 30 can blow the cooled air into the first storage compartment 21 through the air duct 41 and the fan 42, thereby achieving cooling and dehumidification of the first storage compartment 21. As for the second storage compartment 22, since the damper is closed, the cooled air blown into the air duct 41 by the refrigerated evaporator 30 will not affect the second storage compartment 22.

[0035] In this embodiment, when the refrigerated evaporator 30 is turned on, that is, during the refrigeration process, the air in the second storage chamber 22 circulates. When the high-temperature air comes into contact with the low-temperature cold air generated by the refrigerated evaporator 30, frost forms on the surface of the refrigerated evaporator 30. The temperature of the cold air in the first storage chamber 21 decreases, and the humidity also decreases accordingly, thereby achieving the control of reducing the humidity in the first storage chamber 21.

[0036] In this embodiment, when the refrigerated evaporator 30 is closed and stops cooling (i.e., no low-temperature refrigerant flows through the evaporator), the circulation in the second storage chamber 22 exchanges heat with the refrigerated evaporator 30 through the heat of the high-temperature air in the second storage chamber 22, causing the frost on the refrigerated evaporator 30 to melt and the water content in the cold air to increase. The cold air with increased water content is then carried into the first storage chamber 21 through the air duct 41 and the fan 42, increasing the humidity in the first storage chamber 21 and thus achieving the control of increasing the humidity in the storage chamber.

[0037] The refrigeration equipment provided in this application embodiment, when the refrigeration equipment 10 is in use, when it is necessary to reduce the humidity in the first storage room 21, absorbs heat by opening the refrigeration evaporator 30, reducing the water content in the cold air, and blows the cold air with reduced water content through the air duct 41 and the fan into the first storage room 21 with the air damper open, thereby reducing the humidity in the first storage room 21. When it is necessary to increase the humidity in the first storage room 21, the refrigeration evaporator 30 is closed, and the heat from the high-temperature air in the second storage room 22 with the air damper open is used to heat the refrigeration evaporator. Heat exchange is performed on the evaporator 30 to melt the frost on the refrigeration evaporator 30, thereby increasing the water content in the cold air. The cold air with increased water content is blown through the air duct 41 and the fan 42 to the first storage compartment 21 with the air door open, thereby increasing the humidity in the first storage compartment 21. This ensures that the items in the storage compartment are stored at the most suitable humidity for preservation. Without the need for additional high-cost devices to be installed in the refrigeration equipment, the humidity of the storage compartment is controlled, the preservation effect of the items in the storage compartment is improved, and the production cost of refrigeration equipment with humidity control function is reduced.

[0038] In an optional embodiment, at least one humidity sensor is provided in both the first storage compartment 21 and the air duct 41.

[0039] In this embodiment of the application, the sensor installed in the first storage room 21 is used to monitor the humidity in the first storage room 21 in real time, so that when the humidity in the first storage room 21 is inconsistent with the humidity range required by the items placed in the first storage room 21, the humidity in the first storage room 21 can be adjusted in time, thereby extending the freshness of the items in the first storage room 21.

[0040] In this embodiment of the application, when multiple humidity sensors are installed in the first storage room 21, the humidity in the first storage room 21 is obtained by averaging the humidity of each humidity sensor.

[0041] In this embodiment, since the cold air used to adjust the humidity 21 of the first storage room is transmitted to the first storage room 21 through the air duct 41, the sensor installed in the air duct 41 is used to detect the humidity in the air duct 41 in real time when the humidity in the first storage room 21 is adjusted, so as to ensure that the humidity of the air duct 41 meets the humidity requirements of the first storage room before the cold air in the air duct is transmitted to the first storage room 21 for adjustment, thereby improving the efficiency and accuracy of humidity adjustment in the storage room.

[0042] In this embodiment, when multiple humidity sensors are installed in the air duct 41, the humidity sensors can be installed at specific intervals according to the length of the air duct, or one humidity sensor can be installed near the air door corresponding to each storage room. When determining the humidity of the air duct, the weighted result of the humidity detected by all humidity sensors can be used as the humidity of the air duct 41. When humidity sensors are installed at specific intervals, the humidity sensor closer to the first storage room 21 has a higher weight. When one humidity sensor is installed for each air door, the humidity sensor installed near the air door corresponding to the first storage room 21 has the highest weight, and the humidity sensor installed near the air door corresponding to the storage room farther away from the first storage room 21 has a lower weight.

[0043] This application provides a humidity control method applied to refrigeration equipment, such as... Figure 2 As shown, the method includes: S201, Obtain the target humidity range for the first storage room.

[0044] In this embodiment of the application, the target humidity range refers to the storage requirements of the current first storage room in terms of humidity. By obtaining the target humidity range of the first storage room, it is possible to determine whether the current humidity of the first storage room meets the storage requirements based on the real-time humidity of the first storage room. If the humidity does not meet the storage requirements, the humidity of the first storage room can be adjusted in a timely manner.

[0045] In this application embodiment, the target humidity range can be set by the user according to their own needs or according to the storage requirements of different items. The target humidity range represents the humidity range that the user expects to maintain inside the first storage room. For example, in order to better preserve leafy vegetables, the target humidity range may be set to 85%-95%, and in order to better preserve fresh meat, the target humidity range may be set to 75%-85%.

[0046] S202, periodically acquire at least one of the first humidity of the first storage room and the second humidity of the air duct.

[0047] In this embodiment of the application, the first humidity of the first storage room is periodically acquired in order to confirm whether the current humidity of the first storage room meets the storage requirements, that is, to determine whether the current humidity of the first storage room is within the target humidity range.

[0048] In this embodiment of the application, the air duct is used to connect the refrigeration evaporator and at least two storage compartments. Each storage compartment is equipped with an air damper. That is to say, after the cold air generated by the refrigeration evaporator enters the air duct, it can be transmitted to the corresponding storage compartment through the air damper of each storage compartment.

[0049] S203, based on the relationship between at least one of the first humidity and the second humidity and the target humidity range, control the opening or closing of each damper and the refrigeration evaporator so that the first humidity is within the target humidity range.

[0050] In this embodiment, the relationship between the first humidity and the target humidity range includes: the first humidity being within the target humidity range, the first humidity being below the lower limit of the target humidity range, and the first humidity being above the upper limit of the target humidity range. The first humidity being within the target humidity range indicates that no humidity adjustment is currently needed; the first humidity being below the lower limit of the target humidity range indicates that the first humidity in the first storage room needs to be increased; and the first humidity being above the upper limit of the target humidity range indicates that the first humidity in the first storage room needs to be decreased.

[0051] In this embodiment of the application, the second humidity of the air duct is periodically acquired in order to confirm whether the current second humidity of the air duct can adjust the humidity of the storage room whose humidity needs to be adjusted. When the first humidity of the first storage room needs to be increased, the second humidity in the air duct needs to be increased first. When the first humidity of the first storage room needs to be decreased, the second humidity in the air duct also needs to be decreased first.

[0052] In the embodiments of this application, the relationship between the second humidity and the target humidity range includes: the second humidity is within the target humidity range, the second humidity is below the lower limit of the target humidity range and the second humidity is above the upper limit of the target humidity range. The second humidity being within the target humidity range indicates that there is no need to adjust the second humidity of the air duct at present. The second humidity being below the lower limit of the target humidity range indicates that the second humidity of the air duct needs to be increased. The second humidity being above the upper limit of the target humidity range indicates that the second humidity of the air duct needs to be decreased.

[0053] In this embodiment, the humidity in the air duct can be adjusted by turning the refrigerated evaporator on or off. When the refrigerated evaporator is on, the cooling continues and the temperature decreases, and the water content in the cold air in the air duct also decreases accordingly, thus reducing the humidity. When the refrigerated evaporator is off, the surface of the refrigerated evaporator defrosts, and the water content in the cold air in the air duct increases, thus increasing the humidity.

[0054] In this embodiment, the cold air in the duct can be transmitted to the corresponding storage room through the air damper of each storage room. Therefore, by controlling the opening of the storage room air damper, the cold air in the duct is transmitted to the corresponding storage room, thereby adjusting the temperature and humidity of the storage room. By controlling the closing of the storage room air damper, the cold air in the duct is isolated from the cold air in the storage room, thus preventing the cold air in the duct from affecting the temperature and humidity of the storage room.

[0055] In one example, the current temperature and humidity of the first storage room are high, requiring cooling, while the current temperature and humidity of the second storage room are suitable, requiring no adjustment of humidity and temperature. In this case, with the refrigeration evaporator cooling normally, the damper of the first storage room is opened and the damper of the second storage room is closed, so that the cooling capacity generated by the refrigeration evaporator only affects the temperature and humidity of the first storage room, thus reducing the temperature and humidity of the first storage room.

[0056] In this embodiment of the application, if the obtained first humidity is within the target humidity range, it means that the humidity in the current first storage room meets the storage requirements and there is no need to adjust the humidity conditions. Therefore, the refrigeration evaporator remains in its original open state and continues to cool normally, and the air doors of each storage room remain in their original open or closed state without any additional operation.

[0057] In this embodiment, if the obtained first humidity is not within the target humidity range, it indicates that the current humidity in the first storage room does not meet the storage requirements, and the humidity of the first storage room needs to be adjusted so that the adjusted humidity is within the target humidity range. First, the second humidity of the air duct is adjusted by turning the refrigerated evaporator on or off. The second humidity of the air duct is periodically obtained to confirm that the cold air in the air duct can bring the first humidity in the first storage room closer to the target humidity range. Only when the second humidity of the air duct is confirmed to be within the target humidity range can the first humidity of the first storage room be adjusted by the cold air in the air duct. When adjusting the humidity of the first storage room by the cold air in the air duct, the air damper of the first storage room is open.

[0058] The humidity control method provided in this application obtains the target humidity range of the first storage room and periodically obtains the first humidity of the first storage room to determine whether the current first humidity of the first storage room is within the target humidity range. This enables the detection of whether the first humidity of the first storage room needs adjustment. When the first humidity is not within the target humidity range, it indicates that the humidity of the first storage room needs to be adjusted. Since the first humidity is adjusted based on the second humidity of the cold air in the air duct, according to the relationship between the first humidity and the target humidity range, and the relationship between the second humidity and the target humidity range, the opening or closing of each air damper and the refrigeration evaporator is controlled first to ensure that the second humidity is within the target humidity range. Then, the first humidity is adjusted by the cold air in the air duct to ensure that the first humidity is within the target humidity range. This achieves precise control of the humidity of the first storage room, improves the preservation effect of the items in the storage room, and reduces the production cost of refrigeration equipment that implements the humidification technology.

[0059] Based on the above embodiments, as an optional embodiment, if it is determined that the first humidity is not within the target humidity range, the refrigeration evaporator is turned off; and the opening or closing of each damper is controlled according to the relationship between the second humidity and the target humidity range.

[0060] In this embodiment, if it is determined that the first humidity is not within the target humidity range, it indicates that the first humidity needs to be adjusted. Therefore, the refrigeration evaporator is first turned off. When the humidity is adjusted to humidification, the frost on the surface of the refrigeration evaporator is melted by turning off the refrigeration evaporator, increasing the water content in the cold air and thus increasing the second humidity of the air duct. Finally, the first humidity of the first storage room is increased based on the cold air in the air duct. When the humidity is adjusted to dehumidification, when the refrigeration evaporator has just stopped cooling, the surface temperature of the evaporator is still below -10 degrees Celsius. At this time, the cold air undergoes heat exchange, and the moisture in the cold air is also frozen on the surface of the evaporator, which can also reduce the second humidity of the air duct. Finally, the first humidity of the first storage room is reduced based on the cold air in the air duct with reduced humidity.

[0061] In this embodiment, when it is necessary to adjust the first humidity of the first storage room, the second humidity of the second air duct is adjusted first, that is, the second humidity of the second air duct is adjusted to the target humidity range first, and then the humidity of the first storage room is adjusted by the cold air in the air duct. Therefore, when the second humidity is not within the target humidity range, it means that the second humidity needs to be adjusted further. During the adjustment of the second humidity, it is necessary to ensure that the air door of the first storage room is closed to improve the adjustment rate of the air duct humidity. When the second humidity is within the target humidity range, it means that the first humidity of the first storage room can be adjusted based on the cold air in the air duct. Therefore, when the second humidity is within the target humidity range, the air door of the first storage room is kept open.

[0062] In the above scheme, after determining whether humidity adjustment is needed based on the relationship between the first humidity and the target humidity range in the first storage room, the opening or closing of each air damper and the refrigeration evaporator is controlled according to the corresponding humidity adjustment operation to first adjust the second humidity. Then, after determining that no further adjustment of the second humidity is needed based on the relationship between the second humidity and the target humidity range, the opening or closing of each air damper is controlled again to blow the cold air in the air duct into the first storage room, thereby adjusting the first humidity in the first storage room so that the first humidity is within the target humidity range. This achieves precise control of the first humidity in the first storage room and improves the preservation time of the items in the first storage room.

[0063] Based on the above embodiments, as an optional embodiment, if it is determined that the second humidity is not higher than the lower limit of the target humidity range when the first humidity is lower than the lower limit of the target humidity range, then the air door corresponding to the first storage room is closed and at least one air door corresponding to the second storage room is opened.

[0064] In this embodiment, if the first humidity is lower than the lower limit of the target humidity range, it indicates that the current humidity of the first storage room is too low and needs to be humidified. Therefore, the refrigeration evaporator is turned off, and the refrigeration evaporator increases the humidity of the cold air in the air duct by continuously defrosting. The second humidity of the air duct is periodically obtained. If it is determined that the second humidity is not higher than the lower limit of the target humidity range, it indicates that the current humidity of the cold air in the air duct is not high enough and it is necessary to continue to increase the humidity of the cold air in the air duct. During the defrosting process, the air damper of the first storage room is kept closed, and at least one air damper corresponding to the second storage room is opened. The air damper of the first storage room is kept closed because the current humidity of the air duct is not enough to adjust the first humidity of the first storage room to the target humidity range. The air damper corresponding to at least one second storage room is opened to utilize the high temperature air in the second storage room to exchange heat with the frost on the surface of the refrigeration evaporator, that is, to melt the frost on the refrigeration evaporator, thereby increasing the second humidity of the air duct.

[0065] In this embodiment of the application, when the first humidity is lower than the lower limit of the target humidity range, if it is determined that the second humidity is higher than the lower limit of the target humidity range, the air door corresponding to the first storage room is opened and at least one air door corresponding to the second storage room is closed until the first humidity is not lower than the lower limit of the target humidity range.

[0066] In this embodiment, as the frost on the surface of the refrigerated evaporator continues to melt, the second humidity in the air duct will increase. When the second humidity is higher than the lower limit of the target humidity range, it indicates that the cold air in the current air duct can adjust the first humidity of the first storage compartment. Therefore, the damper corresponding to the first storage compartment is opened, allowing the cold air in the air duct to be blown into the first storage compartment by the fan, thereby increasing the first humidity in the first storage compartment. The damper corresponding to the second storage compartment is closed to prevent the cold air in the air duct from being dispersed to multiple storage compartments, thereby reducing the humidification speed of the first storage compartment. When the second humidity is higher than the lower limit of the target humidity range, the above state is maintained, that is, the cold air in the air duct is continuously blown into the first storage compartment until the first humidity of the first storage compartment is not lower than the lower limit of the target humidity range, thereby completing the humidification of the first storage compartment.

[0067] In one example, when the initial humidity level is below the lower limit of the target humidity range, a humidification method is provided, such as... Figure 3 As shown, the specific content is as follows: S301, shut off the refrigerator evaporator; S302, determine whether the second humidity is higher than the lower limit of the target humidity range. If yes, execute S303; otherwise, execute S304. S303, keep the damper corresponding to the first storage compartment in the open state, and keep the damper of at least one second storage compartment in the closed state; S304, keep the damper corresponding to the first storage compartment closed, and keep the damper corresponding to at least one second storage compartment open; S305: Determine if the first humidity level is lower than the target humidity range. If yes, execute S302; otherwise, end the humidification process.

[0068] In the above scheme, when the first humidity is determined to be lower than the lower limit of the target humidity range, it indicates that the current humidity in the first storage room is low and needs to be increased. Therefore, the refrigeration evaporator is turned off. When the second humidity in the air duct is not higher than the lower limit of the target humidity range, it indicates that the second humidity in the air duct needs to be further increased. At least one air vent in the second storage room is opened to allow heat exchange between the refrigeration evaporator and the hot air in the storage room, melting the frost on the surface of the refrigeration evaporator and thus increasing the second humidity of the cold air in the air duct. When the second humidity in the air duct is higher than the lower limit of the target humidity range, it indicates that the current humidity in the air duct is high enough to regulate the first humidity in the first storage room. Therefore, the air vent corresponding to the first storage room is opened, and at least one air vent corresponding to the second storage room is closed, so that the cold air in the air duct only regulates the humidity of the first storage room, improving the efficiency of humidity regulation. The first humidity is continuously regulated by the cold air in the air duct until the first humidity is not lower than the lower limit of the target humidity range, thus completing the regulation of the first humidity.

[0069] In addition, during the process of adjusting the humidity of the first storage compartment through the cold air in the air duct, if the second humidity of the air duct is detected to be lower than the lower limit of the target humidity range again, the corresponding air door of the first storage compartment is closed again, and at least one corresponding air door of the second storage compartment is opened to melt the frost on the surface of the refrigeration evaporator and increase the second humidity of the air duct again until the second humidity is higher than the lower limit of the target humidity range. Then the first humidity of the first storage compartment is readjusted. Through the above process, it can be ensured that the humidity adjustment process is stopped only when the first humidity is successfully adjusted to the target humidity range, ensuring that the items in the first storage compartment are as close to the target humidity range as possible.

[0070] Based on the above embodiments, as an optional embodiment, if the first humidity is higher than the upper limit of the target humidity range, and it is determined that the second humidity is not lower than the upper limit of the target humidity range, then the refrigeration evaporator is started.

[0071] In this embodiment, when the first humidity is higher than the upper limit of the target humidity range, it indicates that the humidity of the first storage room is too high and needs to be dehumidified. Since the first storage room can only be dehumidified when the second humidity in the air duct is within the target humidity range, when the second humidity is not lower than the upper limit of the target humidity range, it indicates that the second humidity in the air duct is still too high and cannot reduce the humidity of the first storage room. Therefore, by activating the refrigeration evaporator, the water in the cold air is cooled and frosts form on the surface of the refrigeration evaporator, thereby reducing the water content of the cold air in the air duct and thus reducing the second humidity.

[0072] In this embodiment of the application, when the first humidity is higher than the upper limit of the target humidity range, if it is determined that the second humidity is lower than the upper limit of the target humidity range, the air door corresponding to the first storage room is opened and at least one air door corresponding to the second storage room is closed until the first humidity is not higher than the upper limit of the target humidity range.

[0073] In this embodiment, if it is determined that the second humidity is lower than the upper limit of the target humidity range during the dehumidification process, it indicates that the cold air in the current air duct can adjust the first humidity of the first storage room. Therefore, the air door corresponding to the first storage room is opened, allowing the air in the air duct to be blown into the first storage room by the fan, thereby reducing the first humidity in the first storage room. The air door corresponding to the second storage room is closed to prevent the cold air in the air duct from being dispersed to multiple storage rooms, thereby reducing the speed of dehumidification of the first storage room. When the second humidity is lower than the lower limit of the target humidity range, the above state is maintained, that is, the air in the air duct is continuously blown into the first storage room until the first humidity of the first storage room is not higher than the upper limit of the target humidity range, thereby completing the dehumidification of the first storage room.

[0074] In one example, when the initial humidity level is higher than the upper limit of the target humidity range, a dehumidification method is provided, such as... Figure 4 As shown, the specific content is as follows: S401, shut off the refrigerator evaporator; S402, determine whether the second humidity is higher than the upper limit of the target humidity range. If yes, execute S403; otherwise, execute S404. S403, Start the refrigerator evaporator; S404, keep the damper corresponding to the first storage compartment in the open state, and keep the damper corresponding to at least one second storage compartment in the closed state; S405: Determine if the first humidity level is higher than the upper limit of the target humidity range. If yes, execute S402; otherwise, end the dehumidification process.

[0075] In the above scheme, when the first humidity level is determined to be higher than the upper limit of the target humidity range, it indicates that the humidity in the first storage room is currently high and needs to be reduced. Therefore, the refrigeration evaporator is first turned off. Before the temperature on the surface of the refrigeration evaporator drops sufficiently to melt the frost, the water in the cold air is allowed to frost on the surface of the refrigeration evaporator, thereby reducing the water content of the cold air in the duct and thus reducing the second humidity. If the second humidity level after dehumidification is still higher than the upper limit of the target humidity range, it indicates that further dehumidification is needed. Therefore, the refrigeration evaporator is turned on again, allowing the water in the cold air to frost on the surface of the refrigeration evaporator once more. Frost reduces the water content of the cold air in the duct, thereby lowering the second humidity until the second humidity is no higher than the upper limit of the target humidity range. This indicates that the current humidity in the duct is low enough to regulate the first humidity in the first storage room. Therefore, the air door corresponding to the first storage room is opened, and at least one air door corresponding to the second storage room is closed, so that the cold air in the duct only regulates the humidity of the first storage room, improving the efficiency of humidity regulation. The first humidity is continuously regulated by the cold air in the duct until it is no higher than the upper limit of the target humidity range, thus completing the regulation of the first humidity.

[0076] In addition, during the process of dehumidifying the first storage room with cold air through the air duct, if the second humidity of the air duct is detected to be higher than the upper limit of the target humidity range again, the refrigeration evaporator will be turned on again to further reduce the humidity in the air duct until the second humidity of the air duct is no higher than the upper limit of the target humidity range. Then the first humidity of the first storage room will be readjusted. Through the above process, it can be ensured that the humidity adjustment process will only stop when the first humidity is successfully adjusted to the target humidity range, thus ensuring that the items in the first storage room are as close to the target humidity range as possible.

[0077] Based on the above embodiments, as an optional embodiment, after controlling the opening or closing of each damper and the refrigeration evaporator, if it is determined that the first humidity is within the target humidity range, the refrigeration evaporator is turned on.

[0078] In this embodiment of the application, after controlling the opening or closing of each damper and the refrigeration evaporator, if it is determined that the first humidity is within the target humidity range, it means that the current humidity of the first storage room meets the storage requirements. Therefore, the refrigeration evaporator is turned on so that the refrigeration evaporator can cool normally.

[0079] In this embodiment of the application, after adjusting the first humidity, which is not in the target humidity range, to the target humidity range, the refrigeration evaporator is kept on when it is already on, and the refrigeration evaporator is turned on when it was originally off.

[0080] In the above scheme, after adjusting the humidity of the first storage room to the target humidity range, the refrigeration evaporator is adjusted to normal cooling state, ensuring the normal operation of the basic functions of the refrigeration equipment.

[0081] Based on the above embodiments, as an optional embodiment, the type of items in the first storage room is obtained; and the target humidity range of the first storage room is determined according to the type.

[0082] In this embodiment, an image of an item can be acquired by a camera installed in the first storage room, and the type of the item can be obtained by image recognition. Alternatively, the user can input the type of the item placed in the first storage room through a terminal, and the terminal will transmit the item type to the bound refrigeration device to obtain the item type.

[0083] In this embodiment of the application, different types of items have different suitable humidity ranges. The humidity ranges corresponding to each type of item are stored in advance. After the type is determined, the target humidity range of the first storage room is determined from the humidity ranges corresponding to each type of item that are stored in advance.

[0084] In the above solution, the target humidity range is determined according to the type of items in the first storage room, ensuring that the items stored in the first storage room are in the most suitable humidity state as much as possible, thus extending the shelf life and freshness of the items.

[0085] In this application, a flowchart of a humidity control method is provided, as shown below. Figure 5 As shown, the specific content is as follows: S501, based on the type of items placed in the first storage room, obtain the target humidity range and the first humidity of the first storage room; S502, determine whether the first humidity is within the target humidity range; if yes, end this round of process; otherwise, execute S503. S503, shut off the refrigerator evaporator; S504: If the first humidity level is determined to be lower than the lower limit of the target humidity range, then determine whether the second humidity level in the air duct is higher than the lower limit of the target humidity range; if yes, proceed to S505; otherwise, proceed to S506. S505, keep the damper corresponding to the first storage compartment in the open state, and keep the damper of at least one second storage compartment in the closed state; S506, keep the damper corresponding to the first storage compartment closed, and keep the damper corresponding to at least one second storage compartment open; S507: Determine if the first humidity is lower than the target humidity range. If yes, execute S504; otherwise, end the current process.

[0086] S508: If the first humidity level is determined to be higher than the upper limit of the target humidity range, then determine whether the second humidity level in the air duct is higher than the upper limit of the target humidity range; if yes, then proceed to S509; otherwise, proceed to S510. S509, Start the refrigeration evaporator; S510, keep the damper corresponding to the first storage compartment in the open state, and keep the damper corresponding to at least one second storage compartment in the closed state. S511: Determine if the first humidity is higher than the upper limit of the target humidity range. If yes, execute S508; otherwise, end the current process.

[0087] This application provides a humidity control device, such as... Figure 6 As shown, the humidity control device 60 may include: an acquisition module 601, a processing module 602, and a control module 603.

[0088] Specifically, the acquisition module 601 is used to acquire the target humidity range of the first storage room; The processing module 602 is used to periodically acquire at least one of a first humidity of the first storage room and a second humidity of the air duct, the air duct being used to connect the refrigeration evaporator and at least two storage rooms, each storage room being provided with an air damper; The control module 603 is used to control the opening or closing of each damper and the refrigeration evaporator according to the relationship between at least one of the first humidity and the second humidity and the target humidity range, so that the first humidity is within the target humidity range.

[0089] The humidity control device provided in this application obtains the target humidity range of the first storage room and periodically obtains the first humidity of the first storage room to determine whether the current first humidity of the first storage room is within the target humidity range. This enables the detection of whether the first humidity of the first storage room needs adjustment. When the first humidity is not within the target humidity range, it indicates that the humidity of the first storage room needs to be adjusted. Since the first humidity is adjusted based on the second humidity of the cold air in the air duct, according to the relationship between the first humidity and the target humidity range, and the relationship between the second humidity and the target humidity range, the opening or closing of each air damper and the refrigeration evaporator is first controlled so that the second humidity is first within the target humidity range. Then, the first humidity is adjusted by the cold air in the air duct so that the first humidity is within the target humidity range. This achieves precise control of the humidity of the first storage room, improves the preservation effect of the items in the storage room, and achieves humidity control of the storage room without the need for additional high-cost devices in the refrigeration equipment, thus reducing the production cost of refrigeration equipment with humidity regulation function.

[0091] In an optional embodiment, the control module 603 is configured to shut down the refrigeration evaporator if it is determined that the first humidity is not within the target humidity range; and to control the opening or closing of each damper according to the relationship between the second humidity and the target humidity range.

[0092] In one optional embodiment, if the first humidity is not within the target humidity range, including if the first humidity is lower than the lower limit of the target humidity range, and if it is determined that the second humidity is not higher than the lower limit of the target humidity range, then the air door corresponding to the first storage room is closed and at least one air door corresponding to the second storage room is opened. If it is determined that the second humidity is higher than the lower limit of the target humidity range, then open the air door corresponding to the first storage room and close at least one air door corresponding to the second storage room until the first humidity is not lower than the lower limit of the target humidity range.

[0093] In one alternative embodiment, the first humidity is not within the target humidity range, including the first humidity being higher than the upper limit of the target humidity range.

Compared with related technologies, this method can achieve the following: by acquiring the target humidity range of the first storage room and periodically acquiring the first humidity of the first storage room, it can determine whether the current first humidity of the first storage room is within the target humidity range. This enables the detection of whether the first humidity of the first storage room needs to be adjusted. When the first humidity is not within the target humidity range, it indicates that the humidity of the first storage room needs to be adjusted. Since the first humidity is adjusted based on the second humidity of the cold air in the air duct, the opening or closing of each air damper and the refrigeration evaporator is controlled according to the relationship between the first humidity and the target humidity range and the relationship between the second humidity and the target humidity range, so that the second humidity is currently within the target humidity range. Then, the first humidity is adjusted by the cold air in the air duct so that the first humidity is within the target humidity range. This achieves precise control of the humidity of the first storage room, improves the preservation effect of the items in the storage room, and reduces the production cost of the refrigeration equipment that implements the humidification technology.
