Electric refrigerator

Abstract

The invention relates to an electric refrigerator comprising a body provided with an inner receiving compartment, a door that is connected to the body in a mobile manner and is used to close the inner receiving compartment, and an air channel system applied to the heat insulation rear wall. Said air channel system comprises a covering plate provided with air outlets, an evaporator arranged between the air channel covering plate and the heat insulation rear wall, and a ventilator. The ventilator is applied horizontally above the evaporator, the air outlets are applied obliquely to the air channel covering plate, and the air flow generated by the ventilator is blown obliquely at an angle to the air channel covering plate, upwards or downwards in the inner receiving compartment.

Description

technical field [0001] The invention relates to a refrigerator, in particular to an air duct system of the refrigerator. Background technique [0002] Refrigerators, especially household refrigerators using an air-cooling system, are usually provided with an air duct system on the rear wall of the refrigerating chamber and the freezing chamber of the refrigerator. The air duct system includes an air duct cover plate installed on the rear insulation wall of the refrigerator or freezer, an evaporator arranged in the gap between the air duct cover plate and the heat insulation wall, and an evaporator arranged at the upper or lower end of the evaporator fan. Several openings are provided on the air channel cover plate, and the rotation of the fan makes the air flow cooled by the evaporator be introduced into the refrigerator compartment or the freezer compartment through the openings, so as to cool the items stored therein.

AI Technical Summary

Problems solved by technology

[0003] US patent application US2006 / 0070395A1 discloses an existing refrigerator with an air duct system. The fan in the air duct system of the refrigerator is placed vertically above the evaporator. Due to the relatively large volume of the fan, the fan motor is partially embedded into the heat insulation wall, thereby reducing the thickness of the heat insulation layer, which is not conducive to the temperature maintenance of the refrigerator freezer

U.S. patent application US2007 / 01576416A1 discloses another improved refrigerator with an air duct system. The fan in the air duct system of the refrigerator is placed horizontally above the evaporator, which overcomes the problem of the fan in US2006 / 0070395A1. However, the common disadvantage of these two U.S. patent applications is that the openings on the air duct cover plate are all perpendicular to the air duct, causing the cold air flow to be exported in a direction perpendicular to the door of the refrigerator compartment. When the door of the refrigerator is in the open position, the cold air flow is blown directly from the refrigerator to the outside of the refrigerator, which increases the energy loss of the refrigerator
