(More specifically, it will be expanded below), which is the scope covered by this embodiment, and therefore is not limited herein. Then, the switch determining unit 1032 can determine whether the humidity of the storage space can be adjusted by using the humidity of the refrigerating space, for example, when the humidity of the storage space needs to be humidified, and if it is determined that the air humidity of the refrigerating space is just large, It can be determined that the humidity of the storage space can be adjusted by using the humidity of the refrigeration space; and, when the humidity of the storage space needs to be dehumidified, and if it is determined that the air humidity of the refrigerating space is just small, it can be determined that the humidity of the refrigerating space can be used to adjust the storage.

More specifically, the determining triggering module may use a preset standard humidity to match the storage space humidity to determine whether the storage space humidity needs to be adjusted, and when it is determined that the storage space humidity needs to be adjusted, triggering the determination to utilize the Whether the cooling space humidity can adjust the storage space humidity toward the standard humidity. Regarding the matching process, for example, it may be determined that the humidification is required when the storage space humidity is lower than the preset standard humidity, and the dehumidification is determined when the storage space humidity is higher than the preset standard humidity. The standard humidity may refer to a certain value or a certain numerical interval, and should belong to the protection range of the embodiment. About this preset The standard humidity may be based on the fact that the refrigerator user has previously set the refrigerator directly or based on the inference, for example, by the stored food of the refrigerator, and should fall within the scope of protection of the present embodiment.

3 is a block diagram showing an example structure of the refrigerating space humidity determining unit 1031 shown in FIG. 2, and the structure shown in FIG. 3 can be regarded as the refrigerating space humidity determining unit 1031 shown in FIG. 2. Further disclosure and optimization, the disclosure of the refrigerating space humidity determining unit 1031 shown in FIG. 3 mainly discloses that the determining process of the refrigerating space humidity may be an indirect calculation process, which is mainly intended to illustrate that it is not necessary to install similarly in the refrigerating space. The device of the humidity detector can save hardware costs. More specifically, the refrigerating space humidity determining unit 1031 includes a refrigerating parameter obtaining module 10311 and a refrigerating space humidity determining module 10312 that are connected to each other. The cooling parameter obtaining module 10311 may obtain the cooling state parameter of the refrigerator, for example, may be directly collected or acquired through interaction with other parameter collecting devices, and the cooling state parameter is indicative of the working state of the refrigerator. The parameters, for example, the total duration of use of the refrigerator, the real-time power consumption of the refrigerator, or the cooling continuous operation time of the refrigerating space 1B, the continuous cooling time of the cooling, etc., are all within the scope of the present embodiment and are not limited herein. Thereafter, the refrigerating space humidity determination module 10312 may determine the refrigerating space humidity based on the refrigerating state parameters. In this embodiment, the humidity of the refrigerating space may be determined by a calculation method, and the derivation process mainly depends on the selected cooling state parameter, and then may be combined with the working principle of the refrigerator (as described in the background section). The real-time refrigerating space humidity is derived in real time; the process of estimating and applying the refrigerating space humidity in the present embodiment will be more specifically exemplified below.

4 is a schematic diagram showing the working principle of the humidity control device according to an embodiment of the present invention, and the embodiment shown in FIG. 4 can also be regarded as further disclosure and optimization of the embodiment shown in FIG. 3, more specifically The cooling state parameter selected in the present embodiment is the cooling continuous working time of the refrigerating space and the cooling continuous dwell time, and thereby the real-time refrigerating space humidity is derived. More specifically, as shown in FIG. 4, the humidity sensor 102 detects the storage humidity R in the storage container with respect to the storage space, and then determines whether R is greater than a preset dehumidification trigger threshold X, when R>X Indicates that the humidity of the storage space is too large, and then continues to determine whether the cooling duration of the refrigerator to the refrigerating space is not less than a predetermined A; and when the cooling duration ≥ A, indicating that the cooling continues for a sufficient time, according to the above The working principle of the refrigerator can be that the humidity of the air in the refrigerating space should be at a low relative level. At this time, the humidity of the storage space can be adjusted by using the air in the refrigerating space, that is, the dehumidification operation is performed by starting the airflow exchange control device, and relatively, when The cooling duration <A indicates that the air humidity of the refrigerating space should be at a high relative level. At this time, it is not appropriate to use the air of the refrigerating space to adjust the air of the drawer (storage space), that is, the air exchange control device is not activated. Avoiding the humidity in the storage space is even larger. When Y ≤ R ≤ X, where Y is the humidification trigger threshold, it indicates that the humidity in the storage space is suitable, that is, the operation of starting the air exchange control device for air exchange is not required. When R<Y, it indicates that the humidity of the storage space is too low, and then the humidification operation should be performed on the storage space. At this time, it should be judged whether the cooling continuous stop time is not less than the preset B, and when the cooling continues to stop. When the time ≥ B indicates that the humidity of the refrigerating space is high relative humidity, the humidity of the storage space can be adjusted by the air of the refrigerating space, that is, the starting air exchange control device 103 is triggered.

The above process of determining and triggering the airflow exchange control device 103 may be performed in synchronization with the working process of the refrigerator, and the dehumidification condition regarding A and the humidification condition regarding B are involved in the determination process; wherein the dehumidification condition needs to satisfy the cooling state The starting time A is due to the fact that the cooling space humidity is at the highest state when the cooling is started. The temperature of the cooling source evaporator needs to decrease for a certain period of time. After the temperature drops, the air moisture condenses and the space humidity decreases. After the starting time A, the cooling space air moisture has decreased. , become dry air can be used to dehumidify. The humidification condition needs to meet the stop cooling time B. It is because the cooling space humidity is at the lowest state when the cooling is just stopped, and the temperature of the refrigeration source evaporator needs to rise for a certain period of time. After the temperature rises, the condensation water condenses and evaporates to replenish the air during cooling, and the space humidity rises. After the start time B, the air moisture in the refrigerating space has increased, and it becomes humid air to be humidified. More specifically, the settings regarding A and B may be related to the refrigeration performance of the refrigerator. More specifically, the difference between X and Y may be maintained at 0% RH to 10% RH (Relative Humidity), thereby maintaining the humidity in the storage space in relative A constant state; and the values for the X and Y may be to allow the refrigerator user to customize the settings, thereby enabling the user to construct a constant humidity space of different humidity for different ingredients and to provide customized customization for the diverse ingredients. Preservation storage environment. More preferably, the values of X and Y may be related to a standard humidity M, such as X=M+buffer value, Y=M-buffer value, which may be set to 0% RH to 5% RH, thereby facilitating The user can set a key, and the buffer value can be unselected to 0 to avoid repeated start and stop of the airflow switching control device 103.

As a further disclosure and optimization, the storage space can be matched by the structural member to achieve a relatively sealed state, such that the air between the cooling space and the refrigerating space cannot be naturally convected, and the air flow exchange control device 103 is disposed in the refrigerating space and the storage space. The airflow exchange control device 103 communicates with one side of the refrigerating space, and one side communicates with the storage space. The activation of the airflow exchange control device 103 can actively replace the air in the refrigerating space and the storage space. Also, the humidity sensor 102 can be in an active state. All or part of the above-described judgment, triggering steps set forth in this embodiment may be performed by a microprocessor (not shown) included in the airflow switching control means 103. More specifically, when the main body of the above judgment and trigger operation is the microprocessor in the airflow exchange control device 103, the microprocessor may be connected to the humidity sensor 102 to receive the storage detected by the humidity sensor 102. Humidity data in the space, and when detecting that the refrigerator meets the humidification condition, outputting an opening and closing command to cause the airflow exchange control device 103 to operate to humidify; correspondingly, when the microprocessor detects that the dehumidification condition is met, the output opening and closing command is output to enable The airflow exchange control device 103 operates to dehumidify.

In the preferred embodiment, the humidity of the refrigeration space of the refrigerator is determined by the cooling timing of the refrigerator, and when the humidity is high, the airflow is exchanged with the storage space that needs to be humidified; when the humidity is low, the storage requiring dehumidification is required. The air space is exchanged in the object space, and there is no need to add a humidity sensor to the induction operation in the refrigerating space, and the cost is low, and the humidity control method can actively utilize the refrigerating space air to adjust the humidity therein to achieve the constant humidity state during the storage of the food in the storage space. It is less affected by storage and is conducive to the preservation of various ingredients (such as dry goods that prefer low humidity and fruits and vegetables that prefer high humidity).
