Description

Antibacterial humidifying device and refrigerator

Technical Field

The invention belongs to the technical field of refrigerators, and particularly relates to a bacteriostatic humidifying device and a refrigerator.

Background

Due to the fact that the overall humidity of the air-cooled refrigerator is low, the fruit and vegetable food materials can be shriveled, dehydrated and damaged to different degrees after being stored in the refrigerating chamber for too long time. Particularly, the relative humidity of the refrigerating chamber of the single-system air-cooled refrigerator is usually less than 20% RH, which is very unfavorable for the preservation of fruits and vegetables. And the single-system air-cooled refrigerator becomes the main development direction of refrigerator design in the industry at present by virtue of the advantages of large volume, high reliability, low cost and the like. Therefore, humidification of single system air-cooled refrigerators has been a difficult problem in the industry. At present, no good humidifying method is available, and the method can be operated easily and can obtain excellent humidifying effect.

In order to solve the problem and further meet the storage requirement of users, some refrigerator enterprises develop in-box humidification technologies, such as closed drawer humidification, ultrasonic humidification, defrosting water humidification, ion humidification and other cold evaporation humidification technologies. For such humidification techniques, sterilization devices such as anion generators, ultraviolet lamps, and the like are also typically provided. For example, compared with patent CN112824797A, the invention provides a refrigerator, wherein a humidifying device and an ion sterilizing device are additionally arranged in a refrigerator body and/or on the inner side surface of a refrigerator door body, so that humidification and sterilization are performed in a refrigerating chamber, the problem that food materials in the refrigerating chamber are easy to air dry is solved, the fresh-keeping effect of the refrigerator is improved, and sterilization and deodorization in the refrigerating chamber are realized.

The existing refrigerator humidifying technology mainly has the following defects:

firstly, a moisture preservation and humidity adjustment drawer is limited by 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 the food materials are easy to deposit harmful gas in a closed environment for a long time and are decayed quickly.

And secondly, the ultrasonic humidifying technology is to form water mist through high-frequency oscillation of the ultrasonic atomizing sheet and disperse the water mist in the air to realize rapid space humidification. 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, frosting and bad frosting of a freezing evaporator of a single-system air-cooled refrigerator and the like.

And thirdly, the defrosting water is collected for humidifying, the water defrosted by the evaporator is blown back to the refrigerating chamber again through a humidifying material or a fan, 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 humidification cannot be realized by using the method.

Fourthly, ion humidification is realized by decomposing the free large water molecule clusters in the 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 compared with the free large water molecule clusters. But this technique also has a problem of insufficient moisturizing effect.

And fifthly, cold humidification, wherein water absorbing materials (corrugated paper, non-woven fabrics and the like) are put into water to increase the evaporation area, then the fan is used for turbulent flow to accelerate the water increase speed, and liquid water is changed into gas state to be diffused into the refrigerating chamber for humidification.

In addition, the various humidification devices are internally provided with a negative ion generator, an ozone generator, a photocatalyst, an ultraviolet lamp and other disinfection and sterilization devices which need to consume electric energy, and parts are easy to rust and break down because the interior of the humidification device works in a high-humidity state (generally more than 90%). Meanwhile, a technology for realizing humidification by introducing condensation, cooling and saturation of fresh air does not exist in the industry of refrigerators, and the comprehensive effect of humidification and bacteriostasis by adding an antibacterial agent into the plastic material of the whole device is not seen.
