Problems solved by technology

Stainless steel materials are more expensive than ordinary metal materials, so the grounding structure of the control panel in the prior art increases the manufacturing cost of the microwave oven accordingly.
[0017] This shows that the grounding structure of the above-mentioned existing microwave oven control panel still has many defects, and it needs to be improved.

Embodiment Construction

[0046] Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects of the present invention will be described in detail as follows.

[0047] see image 3 , Figure 4 , Figure 5 As shown, the grounding structure of the control panel of the microwave oven of the present invention has a control flange 39 on the upper side of the front panel 37 of the microwave oven. The control flange 39 is made of metal material, and a control dial 41 is installed on its front side. The function of the control dial 41 is to input various operation signals for controlling the operation of the microwave oven, and to display various working conditions of the microwave oven externally. The front side of the control flange 39 is formed with at least one connecting hole 39a.

[0048] The control dial 41 is an insulator made of plastic or other materials, and its inner side is extended from the rear side to form at lea...

Abstract

The present invention is the earthing structure of control panel in microwave oven. The control panel of microwave oven is installed on the control flange in the upper end of the front panel of microwave oven, and has outer hood and earthing bracket in the inner side. The head part of the earthing bracket is fixed to the installation trough and contacts the inner side of the hood, and the flange of the earthing bracket and the control flange are connected via screws to the connecting casing of the control dial plate for contacting the front side of the control flange. The hidden earthing structure has no influence on the outer appearance of the microwave oven and the earthing bracket is made of relatively cheap material, rather than stainless steel for lowering the cost of microwave oven.

Description

technical field [0001] The present invention relates to a control panel of a microwave oven, and more specifically relates to a method of connecting the control panel to the body of the microwave oven with a grounding bracket provided inside the control panel, so that the grounding structure is not exposed. Invention in the grounding structure of the control panel of the external microwave oven. Background technique [0002] A microwave oven is a cooking appliance that uses microwaves or a heater as a heat source. The front side of the microwave oven is provided with a control panel. The function of the control panel is to input various operation signals to control the operation of the microwave oven, and to display various working conditions of the microwave oven externally. [0003] figure 1 It is a three-dimensional schematic diagram of the structure of an ordinary microwave oven. As shown in the figure, the inside of the cavity assembly 10 of the microwave oven forms...
