Abstract
The utility model relates a component structure for refrigerators, in particular to an electric ventilation door for a refrigerator. The electric ventilation door for the refrigerator comprises a door panel hinged with a wall board of a cabin of the refrigerator; the door panel can rotate around a hinge shaft so as to open or close the ventilation door; a cam driven by a motor is mounted at one side of the door panel, and the edge of the cam is clung to and presses on the door panel; and a spring capable of driving the door panel to be closed is mounted between the door panel and the wall board. According to the electric ventilation door for the refrigerator, the door panel of the ventilation door is driven to rotate by a cam mechanism, so that the electric ventilation door for the refrigerator has the advantage that the structure is simple, and the manufacturing and the mounting are convenient; besides, due to the characteristics of cam driving, the door panel can be opened at a lower speed through changing the lift angle of the cam, and then a larger torque can be obtained; therefore, the probability that the door panel cannot be opened when being frozen is reduced, and the reliability of the ventilation door can be improved.
Description
Technical field
The utility model relates to a kind of parts of refrigerator structure, specifically is a kind of refrigerator MOD.
Background technology
MOD is parts of controlling cold air flow in the refrigerator between different bins; The conventional electric-powered air door adopts quadric chain to realize the opening and closing control of air door door-plate mostly, and its structure is complicated, and quality of fit is had relatively high expectations between parts; Freeze easily under the air door low temperature, can not reliably open.
Summary of the invention
The utility model technical problem to be solved is, a kind of refrigerator MOD of simple in structure, reliable in action is provided.
The refrigerator MOD of the utility model includes and the hinged door-plate of refrigerator bin wallboard, and door-plate is through around the jointed shaft Unscrew or cut out air door; One side of door-plate is equipped with one by motor-driven cam, and cam edge is pressed on the door-plate; The spring that door-plate cuts out is installed between door-plate and the wallboard.
The utility model adopts cam mechanism to drive the rotation of air door door-plate; Not only simple in structure, manufacturing and easy for installation, and, can change the lift angle of cam owing to cam-actuated characteristics; The realization door-plate is opened with slower speed; To obtain big moment, reduce the probability of door-plate because of freezing and can not opening, improved the reliability of air door.
Description of drawings
Fig. 1 is the structural representation of the air door open mode of the utility model;
Fig. 2 is the structural representation of the air door closed condition of the utility model.
The specific embodiment
As shown in the figure, this refrigerator MOD includes the door-plate 2 hinged with refrigerator bin wallboard 1, and door-plate is through around jointed shaft 3 Unscrews or cut out air door; One side of door-plate is equipped with one by motor-driven cam 4, and cam edge is pressed on the door-plate; The spring 5 that door-plate cuts out is installed between door-plate and the wallboard.
Claims (1)
