Humidifying device for fruit and vegetable room of refrigerator and refrigerator using the humidifying device

Abstract

The invention discloses a humidifying device for the fruit and vegetable chamber of a refrigerator. The fruit and vegetable chamber comprises a partition board and a drawer, the drawer is arranged below the partition board in a sliding manner so as to form a storage space, the humidifying device is a mechanical humidifying device and comprises a pressing part, the pressing part is arranged on the drawer or the partition board, and when pressure is exerted onto the pressing part of the humidifying device, the humidifying device can carry out humidifying actions. According to the humidifying device for the fruit and vegetable chamber of the refrigerator, when humidifying is required, the humidifying device is started for humidifying the fruit and vegetable chamber during the process that the drawer of the fruit and vegetable chamber of the refrigerator is closed, and the fresh-keeping time of fruits and vegetables inside the fruit and vegetable chamber can be effectively prolonged. Therefore the fresh-keeping effect of the fruits and vegetables is enhanced, the humidifying device has a simple structure, electrical components are not required, and potential safety hazards are avoided.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a humidifying device used in a fruit and vegetable compartment of a refrigerator, and a refrigerator using the humidifying device. Background technique [0002] The study found that the humidity condition in the storage environment of fruits and vegetables is one of the important factors affecting the storage quality of fruits and vegetables. The humidity requirement for fruit and vegetable storage is generally above 90%, which can effectively prevent the water loss of fruits and vegetables in the storage environment. In addition, fruits and vegetables also have strict requirements on the wind speed in the storage environment. Studies have shown that when the wind speed is greater than 0.3m / s, it is easy to cause air drying and affect the quality of fruits and vegetables. Therefore, in order to maintain the original freshness and flavor of fruits and vegetables to the grea...

AI Technical Summary

Problems solved by technology

[0003] At present, the humidity of refrigerators on the market generally fluctuates between 30% and 70%, and the range of humidity fluctuations is large and cannot meet the optimal humidity requirements for fruit and vegetable storage.

Fruits and vegetables placed in the fruit and vegetable compartment of such a refrigerator are prone to wilting due to lack of water

[0004] On the other hand, the humidifiers in existing refrigerators mainly use atomization methods such as electrostatic atomization and ultrasonic atomization. The structures of the above humidifiers are relatively complicated, with many electrical components and inconvenient maintenance.

There are also some humidifying devices composed of a water storage and a capillary water absorber inserted in it. These humidifiers need to use air ducts or fans to blow mist into the storage room. This humidifying device is suitable for air-cooled refrigerators, not suitable for Direct-cooling refrigerators, and in air-cooling refrigerators, the ambient wind speed is relatively high. The high wind speed not only directly affects the storage quality of fruits and vegetables, but also with the circulation of the wind, the mist is taken away, which is not conducive to maintaining the humidity in the storage room.
