Refrigerating and freezing device

Abstract

The invention provides a refrigerating and freezing device. The refrigerating and freezing device comprises a box body, a refrigerating system, a first water storage tank, a second water storage tank and a humidifying element, wherein a refrigerating chamber is defined in the box body; the refrigerating system is used for providing cold energy for the refrigerating chamber; the first water storage tank is controlled to receive defrosting water generated during defrosting of the refrigerating and freezing device; the second water storage tank is controlled to receive the defrosting water from the first water storage tank; and the humidifying element is arranged in the second water storage tank and is controlled to start to humidify the refrigerating chamber. The first water storage tank is used for storing the defrosting water as much as possible during defrosting of the refrigerating and freezing device, so that humidifying water is made sufficient to the greatest extent; and meanwhile, it can be guaranteed that the water level in the second water storage tank is basically kept at the best humidifying water level for the humidifying element.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigeration and freezing device. Background technique [0002] Prolonging the freshness of fruits and vegetables, in addition to the key factor of temperature, humidity also has a huge impact on it. According to the research of relevant food research institutions, in general, fruits and vegetables in high humidity (>90% RH) environment, the preservation period of fruits and vegetables is longer, The quality is better. In order to maintain the high-humidity environment in the fruit and vegetable room, sealing control and active humidification are generally used. However, the sealing control method cannot accurately control the humidity in the fruit and vegetable room; improper control of the active humidification method will cause serious leakage, which will accelerate the spoilage of fruits and vegetables. At the same time, the existing active humidificati...

In order to maintain the high-humidity environment in the fruit and vegetable room, sealing control and active humidification are generally used. However, the sealing control method cannot accurately control the humidity in the fruit and vegetable room; improper control of the active humidification method will cause serious leakage, which will accelerate the spoilage of fruits and vegetables.

At the same time, the existing active humidification module needs to continuously store water manually, which is complicated to operate; and after the water is stored in the water storage box for a long time, new bacteria will reproduce and easily cause secondary pollution
