The plurality of storage compartments include, for example, a refrigerating compartment 2 , a changing compartment 3 and a freezing compartment 4 from top to bottom.

The refrigerating chamber 2 is a storage chamber for refrigerating and storing articles. In order to prevent the stored articles from freezing, the temperature inside is generally set in a refrigeration temperature range, usually 1°C to 10°C.

The temperature changing room 3 is a storage room whose temperature can be switched as needed, and can be switched, for example, between the above-mentioned refrigerating temperature zone, freezing temperature zone, or other preset temperature zones.

The freezer compartment 4 is a storage compartment for refrigerating and storing articles, and the temperature inside is generally set in a freezing temperature range, usually -23°C to -15°C. In addition, in order to improve the state of cryopreservation, for example, the minimum temperature may be set to an arbitrary value between -30°C and -23°C.

In addition, the plurality of storage compartments of the refrigerator 1 are not limited to the above-mentioned refrigerating compartment 2, changing room 3, and freezing compartment 4, but may also include compartments having other various functions.

In the present invention, the refrigerator 1 is further provided with a humidification compartment 100 (ie, a storage compartment) specially used for storing items that need to be humidified and preserved, such as fruits, vegetables, and red wine. By controlling the inside of the humidification compartment 100 to be highly humidified, the freshness of the vegetables, fruits, wine, and the like stored in the humidification compartment 100 can be maintained. In addition, in the present invention, as a mechanism for high humidification, a method of spraying water mist by the humidifier 110 is adopted.

In addition, the water tank 111 is preferably disposed on the cover plate 102 in a detachable manner relative to the cover plate 102 , so that the user can take out the water tank 111 to add water, which is convenient for adding water to the humidifying device 110 . In addition, the water tank 111 may be formed integrally with the cover plate 102 , that is, a concave portion for water storage may be formed in the cover plate 102 . In this case, a water filling port may be provided on the top of the water tank 111 , that is, the concave portion, and a cover may be provided on the water filling port. Thereby, the space occupied by the humidifier 110 can also be reduced.

The above describes an example in which the humidifying device 110 has one water tank 111 and one atomizing element 112 respectively, but multiple water tanks 111 and/or multiple atomizing elements 112 may be provided as required. For example, the humidifying device 110 may include a water tank 111 and a plurality of atomizing elements 112, and the water tank 111 and the plurality of atomizing elements 112 are connected through a plurality of water supply paths 114, so that the water mist can be sprayed in the humidifying compartment 100 Spread more evenly.
