[0002] With the improvement of the quality of life, people's requirements for food quality are getting higher and higher. They are no longer satisfied with the mere refrigeration function of refrigerators. There are more and more functional requirements for refrigerators. Fresh fruits and vegetables have a high water content. During storage in the refrigerator, fruits and vegetables will gradually evaporate and lose water. When the water loss rate reaches more than 5%, there will be obvious water loss and wilting, affecting their freshness. Therefore, humidity control is particularly critical during the storage and preservation of fruits and vegetables. If the humidity is too high, it will cause microorganisms to multiply and cause fruits and vegetables to rot and deteriorate. If the humidity is too low, the evaporation rate of water in fruits and vegetables will accelerate, resulting in a decrease in the freshness of fruits and vegetables. At the same time, the most suitable storage humidity for different fruits and vegetables will also be different. Therefore, during the storage of fruits and vegetables, reasonable control of humidity can maximize the preservation effect.

The branch pipe 30 is arranged between every two drawers 3, and multiple atomizing nozzles 31 are arranged in an array on the surface of the branch pipe 30.

[0036] In the present embodiment, when humidification is performed, the controller controls the water pump to start, and the water pump draws the water in the water tank 4 into the water pipe 29. Then the water enters the diverter pipe 30 through the water pipe 29, and then is sprayed out from the atomizing nozzle 31 to humidify the moisturizing chamber 2. The drawers 3 are arranged as a multi-layer structure, each of which is provided with a drain port to avoid water accumulation. The diverter pipe 30 is arranged crosswise with the drawers 3, and the diverter pipe 30 is arranged between two drawers 3, and the number of the diverter pipes 30 corresponds to the number of layers of the drawers 3, so that the moisturizing is more uniform.

[0039] During use, when it is necessary to store food in the moisturizing bin 2 for preservation, the drawer 3 is pulled out from the moisturizing bin 2, and then the food is placed in the drawer 3, and then the drawer 3 is reset, and then a reference humidity matching the food is selected according to the stored food, and the real-time humidity in the moisturizing bin 2 is obtained through the humidity sensor in the moisturizing bin 2, and the obtained real-time humidity is compared with the reference humidity, if the real-time humidity in the moisturizing bin 2 is lower than the reference humidity, the humidification device is started by the controller to humidify the moisturizing bin 2, and if the real-time humidity in the moisturizing bin 2 is higher than the reference humidity, the dehumidification device (not shown in the figure) is started by the controller to dehumidify, so that the humidity in the moisturizing bin 2 is adapted to the matching humidity, so as to maintain the freshness of the food in the moisturizing bin 2 and increase the storage time.

[0040] When humidifying, the controller controls the water pump to start, and the water pump draws the water in the water tank 4 into the water pipe 29. Then the water enters the diversion pipe 30 from the water pipe 29 and is then sprayed out from the atomizing nozzle 31 to humidify the moisturizing chamber 2.

[0042] When the drawer 3 is forgotten to be closed or not closed tightly after opening, the humidity in the moisturizing chamber 2 will be lost, thereby affecting the moisturizing effect. A contact sensor is arranged on the inner wall of the moisturizing chamber 2 to detect whether the drawer 3 is in an open state. When the drawer 3 is detected to be opened, the abnormality detection module is used to detect whether there is an abnormality when the drawer 3 is opened. The specific process is as follows: Obtain abnormal detection data when the drawer is opened, including the drawer opening time sQ, the humidity change amplitude sW when the drawer is opened, and the odor substance concentration sE when the drawer is opened; obtain abnormal detection parameter data when the drawer is opened, including the parameter drawer opening time cQ, the humidity change amplitude cW when the drawer is opened, and the odor substance concentration cE when the drawer is opened; obtain the abnormal detection allowable deviation data when the drawer is opened, including the humidity change amplitude allowable deviation value when the drawer is opened sW and allowable deviation of odor concentration when drawer is opened sE; Determine the abnormality detection assessment value HA based on the abnormality detection data when the drawer is opened, the abnormality detection parameter data when the drawer is opened, and the allowable deviation data of the abnormality detection when the drawer is opened; judge whether the abnormality detection assessment value is greater than the abnormality detection assessment threshold when the drawer is opened stored in the database; if the abnormality detection assessment value is not greater than the abnormality detection assessment threshold when the drawer is opened stored in the database, it is judged that there is no abnormality; if the abnormality detection assessment value is greater than the abnormality detection assessment threshold when the drawer is opened stored in the database, it is judged that there is an abnormality.

[0043] The calculation formula of the anomaly detection assessment value HA is as follows: ; When it is determined that there is an abnormality, the controller controls the drive motor 6 to start, and the drive motor 6 drives the transmission rod 7 to rotate through the output shaft, and the transmission rod 7 drives multiple transmission gears 8 to rotate, and the transmission gear 8 drives the transmission rack 9 meshing with it to move, so that the transmission rack 9 drives the drawer 3 to close, and the drawer 3 slides along the slide rail on the inner top of the moisturizing bin 2 through the slide bar 10 on its top to guide the drawer 3, so as to achieve automatic closing of the drawer 3, avoid affecting the moisturizing effect, and reduce energy consumption.
