Abstract

This invention provides a controlling part of microwave oven, which comprises a control panel with at least one earth connection slot setting in one lateral of the oven, and in the circuit board inside the control panel it has at least one earth connection slot corresponding to said earth connection slot; the front of the control panel also comprises a earth connection slot sequentially go through the control panel and circuit board, and a control cover with at least one earth connection part connecting to the microwave body. Said structure can prevent the internals in the controlling part hurting by the external electrostatic; besides, in the rear of the control cover it set a metal board to prevent the inner fire hazard going outside with lower cost.

Description

technical field [0001] The present invention relates to a microwave oven, and particularly relates to an invention of a control unit for a microwave oven. Background technique [0002] Recently, in order to enhance the appearance of microwave ovens, the front lids of microwave ovens on the market are made of metal materials. Such as figure 1 Shown, be that the lid of prior art microwave oven is made of metal material. [0003] As shown in the figure, the structure of the microwave oven includes a body 1 with a rotatable door 3 on the front side of the body 1 . The door 3 can selectively open and close the cooking chamber (not shown) inside the body 1 , and a door handle 5 is provided on one side of the door 3 . [0004] The front of the above-mentioned door 3 is a door cover 7 . Door cover 7 shows the front appearance of door 3, in order to improve the grade of product, generally selects metal material to make for use. [0005] There is a control part 9 on the front of ...
