External gas flow -in preventing device of electric refrigerator

Abstract

A device for preventing external air from flowing into refrigerator when its door is opened features that a channel on the back plate of cold storage chamber is communicated to the cold storage chamber and a blower is arranged before said channel to generate to cold air flow toward the front of cold storage chamber, so preventing external high-temp air from flowing into cold storage chamber.

Description

technical field [0001] The present invention relates to a refrigerator, in particular to a device for preventing the inflow of external air into the refrigerator, which has the following effects: when the door of the refrigerator is opened, it can prevent to the greatest extent the air caused by the intrusion of warm outside air into the interior of the refrigerator. The inside of the refrigerator becomes high temperature. Background technique [0002] The structure of a prior art refrigerator will be described below with reference to the accompanying drawings. [0003] figure 1 A sectional view showing the structure of a prior art refrigerator. Such as figure 1 As shown, the refrigerator is generally divided into a freezer compartment 2 and a refrigerator compartment 4, and the refrigerator compartment and the freezer compartment are provided with doors 6, 8 respectively. [0004] An evaporator 10 is provided in the heat exchange room 11 behind the freezer compartment 2...

AI Technical Summary

Problems solved by technology

[0005] However, the prior art refrigerator with the above-mentioned structure has the following disadvantages: when taking out or putting in food, the user needs to open the door 8 of the above-mentioned refrigerating chamber 4, and then the relatively high temperature external air will flow into the inside of the refrigerator

That is to say, the contact between the food refrigerated and stored in the refrigerator and the food with relatively high temperature will reduce the freshness of the food, so it is not conducive to keeping the food that needs to be stored for a long time fresh

[0006] In practice, it is desirable that when the door of the refrigerator is opened, outside air cannot flow into the interior of the refrigerator

However, when the door of the refrigerator is opened, outside air will naturally flow in, so it is considered impossible to completely cut off the inflow of outside air.
