Description

Refrigerator with humidification function

Technical Field

The invention relates to the field of refrigerating devices, in particular to a refrigerator with a humidifying function.

Background

Refrigerators are classified into single system refrigerators and multi-system refrigerators according to the number of evaporators. The single-system air-cooled refrigerator is a main direction of refrigerator design in the industry at present due to the advantages of large volume, high reliability and low cost, and gradually replaces a multi-system air-cooled refrigerator in the future.

However, the air-cooled refrigerator has low overall humidity, so that the fruit, vegetable and other food materials are stored in the refrigerating chamber for a long time and are shriveled, dehydrated and damaged to different degrees, and the nutrition of the food materials is damaged. In particular, single system air-cooled refrigerators, the relative humidity in the refrigeration compartment is typically less than 20% RH, which is highly detrimental to the preservation of fruit and vegetables.

In order to solve the problem and further meet the storage requirements of consumers, some refrigerator enterprises develop in-box humidification technologies, such as closed drawer humidification, ultrasonic humidification, defrosting water humidification, ion humidification and the like, and cold evaporation humidification technologies.

For the moisture-preserving and humidity-adjusting drawer, due to the limitation of the size of the drawer, the use requirement of a user for storing a large amount of fruit and vegetable food materials in a conventional refrigerating chamber at one time cannot be met, and harmful gas is easy to deposit when the food materials are in a closed environment for a long time; the ultrasonic humidifying technology is that water mist is formed through high-frequency oscillation of an ultrasonic atomizing sheet and is dissipated in air, and space rapid humidifying is achieved. Although the technology can quickly improve the humidity level in the space, the atomization sheet is easy to lose effectiveness, consumes water quickly, has high water quality requirement, and has the defects of condensation caused by overhigh local humidity, severe frosting of a freezing evaporator of a single-system air-cooled refrigerator and the like; the defrosting water humidification is that the water after defrosting of the evaporator is collected and then blown back to the refrigerating chamber again through the humidifying material or the fan, so that the humidifying effect is good, and condensation is not easy to occur. But the refrigerating chamber of the single-system air-cooled refrigerator in the current market has no evaporator, and the method cannot be used for humidifying; ion humidification is realized by decomposing free large water molecule clusters in air into smaller water molecules and carrying ions through high-voltage ionization, and the charged water molecules are easier to be absorbed by fruits and vegetables than the free large water molecule clusters. But the technology also has the problem of insufficient moisturizing effect; the cold humidification is to increase the evaporation area by putting water absorbing materials (corrugated paper, non-woven fabrics and the like) in water, increase the water increasing speed by turbulent flow of a fan, change liquid water into gas state to diffuse to a refrigerating chamber for humidification.

Therefore, the humidification of the single-system air-cooled refrigerator is always a difficult problem in the industry, and no good humidification method exists at present, so that the operation is easy, and the excellent humidification effect can be obtained.
