Refrigerating chamber humidification system of air-cooling refrigerator and air-cooling refrigerator having refrigerating chamber humidification system

Abstract

The invention provides a refrigerating chamber humidification system of an air-cooling refrigerator. The refrigerating chamber humidification system comprises a switch, a heat exchanger, a water storage device, a humidification device and a controller, wherein the heat exchanger is communicated with an air channel of the refrigerator through the switch; the water storage device is used for storing condensed water defrosted on the surface of the heat exchanger; the humidification device is connected with the water storage device and used for gasifying the condensed water in the water storage device and humidifying a refrigerating chamber; and the controller is connected with the switch and the humidification device and used for controlling on and off of the switch according to temperature of the refrigerating chamber and controlling the humidification device to humidify the refrigerating chamber when the temperature of the refrigerating chamber is lower than predetermined temperature. The invention also provides an air-cooling refrigerator. By the refrigerating chamber humidification system of the air-cooling refrigerator, a humidity requirement of the refrigerating chamber on vegetable and fruit storage can be met, and a humidification effect is obvious. The air-cooling refrigerator having the refrigerating chamber humidification system is low in energy consumption, can keep high humidity of the refrigerating chamber for long time and has the advantage of small humidity variation.

Description

technical field [0001] The invention relates to the technical field of humidification of refrigerators, and particularly designs an air-cooled refrigerator refrigerated room humidification system and an air-cooled refrigerator equipped with the refrigerated room humidified system of the air-cooled refrigerator. Background technique [0002] The level of moisture retention in the freezer compartment of the refrigerator directly affects the storage time for vegetables and fruits to keep fresh. In daily life, most vegetable products generally have good fresh-keeping quality only when the humidity reaches above 60% RH. Therefore, high-humidity fresh-keeping technology has always been the technical development direction of refrigerator-refrigerated food. High-quality vegetables and fruits can effectively prolong their storage time in a low-temperature and high-humidity environment, and can maintain their high moisture and nutrients. At present, refrigerators are mainly divided i...

AI Technical Summary

Problems solved by technology

At present, refrigerators are mainly divided into direct-cooling and air-cooling. In the refrigerator market at home and abroad, all brands of refrigerators have high-humidity and fresh-keeping refrigerator products, but these products are all direct-cooling refrigerators. The function of high-humidity fresh-keeping has not been effectively realized

[0003] like figure 1 As shown, in the existing air-cooled refrigerator, the refrigerating chamber and the freezing chamber are connected by the air duct 11' during the refrigerating process. and the freezer, the moisture in the air will change from gaseous to solid and frost when passing through the finned evaporator 12', thus causing the refrigerator and freezer to be relatively dry

However, the vegetables and fruits stored in the cold room have high requirements on humidity, and the suitable storage humidity is generally between 60%RH and 80%RH. Because most of the moisture in the air during the cooling process of the existing air-cooled refrigerator Frost has formed on the finned evaporator 12', causing the humidity of the air in the refrigerator to generally only be maintained between 10%RH and 15%RH, such as figure 2 35% RH is only occasionally reached when defrosting as shown

Therefore, it is far from reaching the humidity index of 60% RH ~ 80% RH, so it cannot meet the requirements of high humidity preservation
