Small-volume horizontal frostless refrigerator

Abstract

The invention discloses a small-volume horizontal frostless refrigerator which comprises a refrigerator body and a door body, wherein the refrigerator body is internally provided with an air duct system; the air duct system comprises an evaporator, a supply fan, an air intake duct and an air return duct; the evaporator is located in a cavity of the evaporator; a fan cover covers in a chamber; an evaporator temperature sensor, a defrosting heater and a defrosting protector are arranged on the evaporator; an evaporator water collection disk is arranged below the evaporator; the air intake duct comprises a plurality of air intake sub-ducts arranged in an interlayer of the fan cover; the air intake sub-ducts are dispersed and distributed at the periphery by taking the supply fan as a center; an inlet end of each air intake sub-duct is communicated with the supply fan; an outlet end of each air intake sub-duct is connected with an air outlet; the air outlets are distributed at the upper part, the middle part and the lower part of the front side of the fan cover. The refrigerator has the advantages that the purpose of automatic defrosting can be achieved on the premise of low cost.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a small-volume horizontal frost-free refrigerator. Background technique [0002] As a convenient refrigeration tool, the horizontal freezer is widely used in commercial and household fields. Considering the cost and manufacturing process, the horizontal refrigerators on the market all adopt the direct cooling method, that is, the evaporator pipe is wrapped around the inner tank to foam, and a drain pipe is installed at the bottom of the cabinet. This method causes the common faults of the horizontal freezer - severe frosting and laborious opening of the door. After the user uses it for a period of time, a thick frost layer is formed on the inner tank of the freezer due to condensation of water vapor. The user can only cut off the power, take out the food, and discharge the frost through the drain after melting. In addition, with this refrigeration method, a larg...

AI Technical Summary

Problems solved by technology

In addition, with this refrigeration method, a large pressure difference will be formed inside and outside the freezer, and it is quite laborious for the user to open the door for the second time.

[0003] The freezer is generally much longer than the refrigerator in the width direction, and the general freezer does not have a shelf similar to a refrigerator, so the freezer is prone to blockage of the air passage and insufficient air supply distance

In view of this phenomenon, an extended air duct can be designed in the freezer box, but this kind of extended air duct has very high cost, process and installation requirements for production. Refrigerator, the width of the cabinet is small, and the cost of all aspects is too high if the extended air duct is used, so it is not suitable for popularization and mass production
