Refrigerating and freezing device with automatic defreezing function

Abstract

The invention discloses a refrigerating and freezing device with an automatic defreezing function. The refrigerating and freezing device comprises a rack 1. A motor 11 is fixed to the bottom end of the rack 1. The tail end of the motor 11 is in power connection with a first rotating shaft 13 extending up and down. A first transmission groove allowing the first rotating shaft 13 to penetrate is formed in the middle of the rear end of the rack 1. An air blasting assembly for performing air blasting on freezing is arranged in the first transmission groove. The air blasting assembly comprises a first bevel gear 71 rotationally connected with the first rotating shaft 13. A second bevel gear 72 is rotationally mounted on the front side of the first bevel gear 71. A driving shaft 76 is fixedly mounted at the center of the second bevel gear 72. A first fixing block 74 is rotationally mounted on the outer portion of the front side of the driving shaft 76 through a bearing. When the device works, the freezing area can be blown and defreezed, meanwhile, a scraper can repeatedly clean the freezing area below a partition, the operation is simple, and the working efficiency is high.

Description

technical field [0001] The invention relates to the technical field of refrigerating and freezing, in particular to a refrigerating and freezing device capable of automatic defrosting. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. There are compressors, refrigerators or cabinets for freezing in the box, and storage boxes with refrigeration devices. It is understood that most of the water vapor comes from the air. When people store food and open the refrigerator, the indoor air and the gas in the refrigerator exchange freely, and the humid air in the room quietly enters the refrigerator. Another part of the water vapor comes from the food stored in the refrigerator, such as cleaned vegetables and fruits in fresh-keeping boxes. The water in vegetables and other food evaporates and condenses into fros...

AI Technical Summary

Problems solved by technology

Some refrigerators need to be defrosted, artificial refrigerator defrosting is time-consuming and laborious, and the defrosting effect is very poor

[0003] At the present stage, when refrigerators and freezers store stored items for a long time, a large number of ice cubes will be generated on the surface of the inner wall of the freezer and under the partition, which not only occupies the space of the storage room but is also very unsightly, and manual cleaning is time-consuming and expensive. low efficiency
