Problems solved by technology

[0004] However, the passive humidification method cannot maintain a high humidity environment when there are few vegetables and other storages, which will lead to dehydration of the vegetables and other storages
The active humidification method cannot intelligently adjust the target humidity according to the type and quantity of vegetables and other storage items

Embodiment approach 1

[0030] figure 1 It is a cross-sectional view schematically showing the overall structure of refrigerator 1 according to Embodiment 1 of the present invention. like figure 1 As shown, the interior of the refrigerator 1 is divided into a plurality of storage compartments by a thermal insulation component made of, for example, rigid polyurethane or expanded polystyrene. The plurality of storage rooms include, for example, a refrigerating room 2, a temperature changing room 3, and a freezing room 4 from top to bottom.

[0031] The refrigerating room 2 is a storage room for refrigerated storage of items. In order not to freeze the stored items, the internal temperature is generally set in the refrigerating temperature range, usually 1°C to 10°C.

[0032] The variable room 3 is a storage room whose temperature can be switched as required, for example, can be switched between the above-mentioned refrigerating temperature zone, freezing temperature zone or other preset temperature z...

Embodiment approach 2

[0066] Use the following Figure 9 , Figure 10 Embodiment 2 of the present invention will be described. Embodiment 2 differs from Embodiment 1 in the configuration of the humidifier, and other structures are the same as those of the refrigerator 1 in Embodiment 1, so descriptions are omitted.

[0067] like Figure 9 , Figure 10 As shown, the humidification compartment 200 has a drawer 201 and a cover plate 202 disposed on the opening of the drawer 201. The inside of the humidification compartment 200 (that is, the internal space of the drawer 201) can be formed into a closed space by the cover plate 202. . In addition, according to needs, a sealing member 202a may also be provided on the lower part of the cover plate 202, for example, the sealing member 202a is in a wedge-shaped shape that protrudes downward as it goes to the inner side. At this time, the side wall of the drawer 201 is formed in a shape that becomes lower in height as it goes toward the inner side corre...

Abstract

The invention provides a refrigerator and a control method of a humidifying device. The refrigerator (1) is provided with a storage compartment (100), the humidifying device (110) for supplying water mist to the storage compartment (100), and a control unit (5) for controlling the on-off of the humidifying device (110) on the basis of a humidity detection value detected by a humidity sensor arranged in the storage compartment (100) and predetermined target humidity. When the humidity detection value is less than the lower limit value of the range of the target humidity, the humidifying device (110) is turned on, and the humidification device (110) is continuously operated for at least first time which is a humidification time required to reach the target humidity under a low humidity condition. Therefore, the humidification speed of the storage compartment can be higher than the outward dissipation speed of the moisture, the humidification amount can be intelligently adjusted according to the current humidity condition and the target humidity, and the situation that due to insufficient humidification, fruits, vegetables and the like are subjected to dehydration weightlessness or due to excessive humidification, the fruits, vegetables and the like are subjected to water corrosion is avoided.

Description

technical field [0001] The invention relates to a refrigerator with a humidification function and a control method for a humidification device. Background technique [0002] In recent years, domestic refrigerators are provided with compartments dedicated to storing vegetables, fruits, and the like. By controlling the high humidity inside the chamber, it is possible to maintain the freshness of vegetables, fruits, etc. for a long time. In addition, as a means of high humidification, for example, a method in which water mist is sprayed by a humidifier is employed. [0003] Humidity control means used in existing refrigerators with humidification function mainly include passive humidification and active humidification. The passive humidification method mainly relies on the evaporation of the water vapor of the vegetables and other stored materials in the vegetable room and the adjustment of the pore size of the vegetable room to control the humidity environment of the vegetab...
