Refrigerator and device for controlling open and closure of ice-making port

Abstract

The invention discloses a refrigerator and a device for controlling open and closure of an ice-making port. The device comprises an direct current motor, a rotating output shaft, an eccentric cam, a fixing part for fixing the eccentric cam, an ice outlet port open-closure transmission part and an ice outlet port door, wherein the rotating output shaft is mutually contacted with the backseat pin on one side of the eccentric cam, the other side of the eccentric cam is provided with a push type baffle which can ensure a transmission part lever to rotate, the push type baffle is in contact with the lever of the ice outlet port open-closure transmission part, and the eccentric cam is sleeved on the fixing part; and the ice outlet port door is installed on the ice outlet port open-closure transmission part, and the backseat pins at two sides of the eccentric cam and the push type baffle have included angles of 45-135 degrees by taking the wheel center of the eccentric cam as a central shaft. By virtue of carrying out simple improvement on the transmission mechanism in a refrigerator ice-making chamber, the space of the whole transmission mechanism is saved, and the better transmission effect can be achieved under the condition of smaller occupied space; and as the modification is slight, large-scale production can be realized without improving the original production facility.

Description

technical field [0001] The invention provides an internal transmission mechanism of a refrigerator and a refrigerator equipped with the device, in particular a refrigerator and a device for controlling the opening and closing of an ice-making opening. Background technique [0002] With the progress of the times, the functions of household appliances are becoming more and more perfect. As one of the representatives of household appliances, the refrigerator is also gradually improving its technology, making the refrigerator more humane, and the functions of the refrigerator are becoming more and more comprehensive. The compact design of the necessary transmission parts inside the body can increase the use space of the refrigerator, which has become the top priority of refrigerator design. As an important part of the refrigerator, the compact design of the ice-making compartment is of great significance for saving space in the ice-making compartment itself. Since the existing d...

Problems solved by technology

[0003] The invention simply improves the transmission mechanism in the ice-making chamber of the refrigerator, so as to solve the problem that the transmission mechanism in the existing design requires a relatively large accommodation space and causes the volume of the ice-making chamber to be too large. The invention provides a method for controlling the opening and closing of the ice-making opening The device includes a DC motor, a rotating output shaft, an eccentric cam, a fixing member for fixing the eccentric cam, an opening and closing transmission part of the ice outlet, an ice outlet door, the rotating output shaft and the rear seat lug on one side of the eccentric cam In contact with each other, the contact point between the rotating output shaft and the ear piece of the rear seat of the eccentric cam, the contact point between the push-type baffle plate and the lever of the transmission part are located on the same side of the eccentric cam, and the other side of the eccentric cam is provided with a device that enables the transmission part to The push-type baffle rotated by the lever, the push-type baffle is in contact with the lever of the opening and closing transmission part of the ice outlet, the eccentric cam is sleeved on the fixing part, and the door of the ice outlet is installed on the ice outlet On the opening and closing transmission part, the rear seat lugs on both sides of the eccentric cam and the push-type baffle form an angle of 45° to 135° with the wheel center of the eccentric cam as the central axis.
