Controlling knob for microwave oven

Abstract

A control knob for a microwave oven, which has a rotary knob and a guide button. The structure of the rotary knob is an outer structure formed on the edge of the ∏-shaped opening, and two arc-shaped insertion grooves are opened on the top surface near the edge. The end corresponding to the arc-shaped insertion groove is separated by a block piece that is integrated with the central disc on the top surface; the guide button is a T-shaped structure, and its top surface forms an arc surface, and a turning point is formed near the edge of the arc surface. The size of the insertion slot on the button is corresponding to the two arc-shaped convex edges that can be inserted into it. At the ends corresponding to the two arc-shaped convex edges, there is a concave part that can be inserted into the blocking piece on the turn button, and the guide key The tail is formed with a lower socket, and the guide button is embedded in the turn button, wherein the convex edge is inserted into the insertion groove. The invention has only two pieces of structure, which reduces the number of knob assembly, facilitates operation during production, improves production efficiency, and reduces production cost due to the reduction of one component. When the microwave oven operates, it is prompted by a ring aperture, which avoids the exposure of the internal structure. The appearance is generous and beautiful.

Description

technical field [0001] The invention relates to a microwave oven. In particular, it relates to a control knob for a microwave oven with a simple structure and convenient installation. Background technique [0002] 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. A microwave oven is generally composed of the following components, that is, a furnace body, which forms the entire appearance of the microwave oven; a cooking chamber, in which the entire barbecue cooking process is carried out; and an electric control room, in which various electrical components are arranged. Wherein, the electric control room is l...

AI Technical Summary

Problems solved by technology

[0004] The current microwave oven knob structure is generally assembled from three parts: knob A, start button B, and guide button C. Due to the assembly of three parts, it increases the difficulty of production operations, reduces production efficiency, and increases the raw materials of the microwave oven. cost

And the light-transmitting start button B and guide button C are generally made of transparent plastic. This structure makes it easy to see through the inner structure of the knob when the microwave oven is not working, which affects the overall appearance of the microwave oven.
