Opening and closing structure of pull-down oven door

Abstract

The invention discloses an opening and closing structure of a pull-down oven door. The opening and closing structure comprises a hinged plate fixedly connected with a microwave oven main body and a rotational structural part rotatablely and fixedly arranged on the hinged plate, the external end of the rotational structural part is hinged to the back side of the furnace door, the rear portion of the rotational structural part is connected with a spring, the rear end of the spring is connected to the hinged plate or the microwave oven main body through a fixed hole, and the fixed hole has a triangular structure, and the vertex corner of the fixed hole is arc-shaped. The fixed hole of the spring is designed to have an equilateral triangle structure with the vertex corner and the basic corners being arc-shaped, and the dimension of the triangular structure is greater than the diameter of the steel wire of the hook portion of the spring, so the assembling is convenient, and the insertion of the steel wire into the fixed hole is easy; and the vertex corner of the triangle is arranged to have an arc having a same diameter with the steel wire of the hook portion of the spring, so the hook can be positioned in the vertex corner in no displacement, stable fixing and small noise without considering the bearing of the spring.

Description

technical field [0001] The invention relates to a microwave oven, in particular to an opening and closing structure for a pull-down microwave oven door. Background technique [0002] Generally speaking, a microwave oven is a machine that cooks food conveniently by turning on the power supply and using the microwave effect generated. In particular, recently, heating sources such as heaters have been installed in addition to magnetrons, and various cooking methods have emerged, that is, cooking methods that circulate the heat generated in the heaters, or cooking by controlling the position of the heaters. method etc. [0003] figure 1 It is a microwave oven door opening and closing structure in the prior art. Such as figure 1 As shown, it has shown a pull-down furnace door opening and closing mechanism, and the furnace door is located at the bottom surface of the microwave oven and can be opened from bottom to top. As shown in the figure, the furnace door 10 is pivoted to...

Problems solved by technology

[0004] However, the connecting hole between the spring 14 and the main body of the microwave oven is a circular or square fixing hole, the stress is relatively concentrated, and the positioning is poor. When the door is opened, the spring will move in it, which is prone to noise, and the reciprocating motion will wear off the hook of the spring. , affecting its lifespan
