Internal icing removal device capable of preventing internal gas and external gas exchange in case of opening of cold storage door

Abstract

The invention discloses an internal icing removal device capable of preventing internal gas and external gas exchange in case of opening of a cold storage door. The internal icing removal device structurally includes a closed extension block, a stressed spindle, a force applying ring and a retractable closed door, and the retractable closed door includes a main rotating body, four fixing columns,a limiting rod, an auxiliary rotating shaft, a retractable scraper, a gas isolation device, a smooth sliding block, a pushing rod, a smooth sliding rail and a closed block; the fixing columns are uniformly and vertically welded to one end face of the main rotating body, and penetrate through one end of the limiting rod and are connected with the limiting rod through hinges; the gas isolation device is located at the top end of the closed block, and is capable of opening a door of a cold store smoothly before opening; and as soon as the door of the cold store is pushed open, a stressed jackingrod loses jacking force of the closed block, moves downwards to produce gas, rushes down through a gas output end, and isolates air on both sides of the stressed jacking rod through the gas so that the jacking force cannot be lost too much.

Description

technical field [0001] The invention belongs to the field of refrigerating devices, and more specifically relates to a device for removing internal ice from opening the refrigerating door to prevent internal and external gas exchange. Background technique [0002] At present, the doors of the hairtail cold storage are relatively thick. At noon in summer, the temperature is the highest. The door of the cold storage can completely isolate the temperature inside and outside, so that the hairtail inside can be better kept fresh. [0003] Based on the inventor's discovery above, the existing cold storage insulation door mainly has the following deficiencies, such as: [0004] 1. In order to ensure the freshness of the product, the temperature inside the refrigerator is below zero degrees. Since the interior is below zero for a long time, it is relatively normal to freeze. The gap between the doors of the refrigerator will be due to the low internal temperature. , so that it is e...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned cold storage for refrigerated hairtail, the door is more likely to freeze if it is not opened for a long time, and the door is bonded to the inner wall of the cold storage. When it needs to be opened, it is more laborious and the door is damaged. After opening, the hot air from the outside is easier to quickly penetrate into the refrigerator, and the cold air inside will also run out, causing the internal temperature to rise sharply, and the refrigerated items are more likely to be affected and deteriorate.
