Embodiment Construction

[0019] like figure 2 - image 3 As shown, the anti-freezing damper of the present invention includes a mounting frame 1 for being arranged in the air duct of an air-cooled refrigerator, the mounting frame 1 is equipped with an air duct opening 2 and a micro motor, the mounting frame 1 is provided with an air duct opening 2, and the mounting frame 1 A flap 3 is hinged, and the output shaft of the micro motor is connected with the flap 3 . The micromotor is a conventional part of the existing electric damper, and the figure does not show the micromotor. When the damper 3 is closed, the air duct opening 2 is closed, and when the damper 3 is rotated to open, the air duct opening 2 is opened, and the damper 3 is provided with a uniform temperature hole 5 . The temperature equalizing holes 5 are preferably uniformly provided with more than three holes on the damper 3, figure 2 Shown in is 5 uniform temperature holes 5 . The uniform temperature hole 5 is preferably circular.

Abstract

The invention discloses an anti-freezing air door which comprises an installation frame, an air flap and a micro motor. The air flap and the micro motor are arranged on the installation frame, an air channel opening is formed in the installation frame, and an output shaft of the micro motor is connected with the air flap. When the air flap is closed, the air channel opening is sealed. When the air flap rotates, the air channel opening is opened. Temperature equalizing holes are formed in the air flap. By means of the holes formed in the air flaps, cooling capacity in a freezing chamber can slightly leaks into a refrigerating chamber through the holes. The invention further discloses an air cooling refrigerator with the anti-freezing air door. Tests show that the temperature of one side of refrigerating chamber can be -19.32 DEG C to -5.45 DEG C after the holes are formed in the air doors. Namely, the temperature of the refrigerating chamber side of the air door is below 0 DEG C. Thus, the whole anti-freezing air door is all in an environment below 0 DEG C, the condensation risk at the air door is reduced, and the air door is prevented from being frozen after the air door is closed or opened.

Description

technical field [0001] The invention relates to the technical field of air-cooled refrigerators, in particular to a damper structure of an air-cooled refrigerator. Background technique [0002] Air-cooled refrigerators mainly rely on air circulation to achieve cooling effect. The refrigeration evaporator pipeline of the air-cooled refrigerator is installed in the freezer, and the fan motor is also installed on the upper part of the evaporator in the freezer. room space. Therefore, a damper is installed between the refrigerating chamber and the freezing chamber, and the temperature of the refrigerating chamber is controlled by controlling the opening and closing of the damper. [0003] It can be seen that the damper is the throat that connects the refrigerator and the freezer. [0004] like figure 1 As shown, the existing electric damper includes a mounting frame 1, on which an air duct opening 2 is arranged, and a damper plate 3 for closing or opening the air duct openin...
