Door hinge and electric oven

Abstract

The invention relates to a door hinge of an electric oven. The door hinge of the electric oven comprises an arm support requiring to be installed on an oven body, and a hinge support requiring to be installed on an oven door. A hinge arm, a pull arm and an elastic element are arranged on the hinge support; the arm support is coupled onto the hinge arm; the hinge arm is hinged onto the hinge support at a hinge point part; the first end of the elastic element is connected with the hinge support; the second end of the elastic element is connected with the pull arm; the pull arm is coupled onto the hinge arm; during an opening process of the oven door, the pull arm overcomes an elastic pull force of the elastic element, and linearly moves toward a direction close to the hinge point along the hinge support, and the hinge support rotates opposite to the hinge arm and the arm support toward a direction far away from the arm support; and during a closing process of the oven door, the pull armis stressed by the elastic pull force of the elastic element, and linearly moves toward a direction far away from the hinge point along the hinge support, and the hinge support rotates opposite to thehinge arm and the arm support toward a direction close to the arm support. The door hinge is simple in structure, easy to assemble and lower in cost. The door hinge structure provided by the embodiment can enable the oven door to automatically maintain pause under the condition of opening at a certain angle so as to be convenient to use.

Description

technical field [0001] The invention relates to a box door hinge and an electric oven. Background technique [0002] Existing electric oven door hinges are divided into two categories, one is that the door is hinged with the box body, that is, the box door can be rotated to open and close on the box body, and an elastic piece is arranged between the box body and the box door, and the elastic piece helps The box door is closed, because its structure is too simple, the elastic force of the elastic parts is not easy to control, even if some auxiliary structures are added, the opening and closing of the box door is still difficult to meet the needs of users; the other is a synthetic hinge, that is, the hinge arm. The rotation and the movement of the elastic member are installed in the same part, so that the box body and the box door can be opened and closed better, but the hinge structure is complicated, which leads to relatively high cost of the electric oven, so the applicatio...
