Refrigerating and freezing equipment

Abstract

The invention provides refrigerating and freezing equipment. The refrigerating and freezing equipment comprises a sealed drawer and a first draught fan; the sealed drawer is arranged in a storage space and comprises a drawer box body and a drawer body; the drawer box body is provided with a forward opening, a fresh-keeping space is defined in the drawer box body, and a containing cavity communicating with the fresh-keeping space is formed in the top wall of the drawer box body; the drawer body is arranged in the drawer box body in a sliding manner; the first draught fan is arranged in the containing cavity, a ventilation hole is formed in the wall face between the containing cavity and the fresh-keeping space, so that the containing cavity and the fresh-keeping space communicate; and a mechanical valve is arranged on the rear wall of the containing cavity and is configured to be blown open under the condition that the first draught fan is started so that the containing cavity can communicate with the exterior of the sealed drawer, and supersaturated water vapor in the fresh-keeping space is discharged out of the sealed drawer through the ventilation hole and the mechanical valve in sequence. According to the refrigerating and freezing equipment, the humidity in the fresh-keeping space is effectively reduced, the problems that the inner wall is condensed, vegetables are rotten, and fruits are ripe too quickly are avoided, and the storage effect of food is improved.

Description

technical field [0001] The invention relates to the field of item storage, in particular to a refrigeration and freezing device. Background technique [0002] With the development of society and the improvement of people's living standards, and people's pace of life is getting faster and faster, people often buy a large number of items placed in various refrigeration and freezing equipment, but for leafy vegetables and melon and fruit foods, refrigeration and freezing The low temperatures in the appliance's storage space not only wrinkle and blotch the skin of these foods, but also affect their original taste and nutrition. [0003] In the fresh-keeping technology of refrigeration and freezing equipment, oxygen is closely related to the oxidation and respiration of food in refrigeration and freezing equipment. The slower the respiration of the food, the lower the oxidation of the food and the longer the preservation time. Reducing the oxygen content in the air has an obvio...

AI Technical Summary

Problems solved by technology

[0006] In the prior art, a sealed space is often set up in the storage space as a fresh-keeping room, but the current sealed space is prone to problems such as excessive internal humidity, elevated oxygen concentration, and high levels of harmful components such as ethylene, resulting in condensation on the inner wall, rotten vegetables, The fruit ripens too quickly, which seriously affects the user experience
