Description

Refrigerator-freezer based on automatically-controlled door

Technical Field

The utility model relates to a door field, concretely relates to refrigerator-freezer based on automatically-controlled door.

Background

The modern society refrigerator-freezer uses especially frequently, but now all is conventional manual opening and closing door basically, and the operation is more troublesome, and current automatic refrigerator-freezer that can open the door is at the in-process of switch, and the part of switching department is because the moment of torsion is too big when opening and closing the door, and is great at the switching department load, and the switch door seems tired more, and user experience feels not good, if open the door too frequently, can make the power consumption of refrigerator obviously increase on the one hand, also can reduce the life of refrigerator simultaneously. Because the door of the refrigerator is large, if the door is opened for a plurality of times, cold air in the refrigerator escapes, and warm and humid air outside the refrigerator enters the refrigerator, the temperature in the refrigerator rises. Meanwhile, the moist air entering the box can easily accelerate the frosting on the surface of the evaporator, and the frosting layer is thickened. Because the coefficient of heat conductivity of frost is much less than that of the evaporator material, it is not favorable to heat conduction, causes the temperature decline slowly in the case, and compressor operating time increases, and wearing and tearing accelerate, power consumption increases. If the thickness of the frosting layer on the surface of the evaporator is larger than 10 mm, the heat transfer efficiency is reduced by more than 30%, and the refrigeration efficiency is greatly reduced.

Patent CN201721133095.X, a horizontal refrigerator door control mechanism that opens and shuts discloses a horizontal refrigerator door control mechanism that opens and shuts, including the cabinet body, establish the cabinet door on the cabinet body, establish the actuating mechanism who opens and shuts to the cabinet door on the cabinet body, be equipped with a pair of actuating mechanism on the cabinet door and carry out automatic control's control module, be equipped with a pair of actuating mechanism on the cabinet door and carry out the control switch that manual or automatic control mode carried out the switching, when control switch was in automatic shelves, actuating mechanism passed through the control module drive, be equipped with the distance inductor of being connected with control module on the cabinet door.
