Problems solved by technology

However, a conventional microwave oven stopper 10, of the same shape and size, is incorporated on the outer edge of the door 4
Therefore, the electromagnetic wave shielding performance of the traditional microwave oven is very poor.
The problem that is not easy to solve is that the shielding of electromagnetic waves near the door hook 8 on the door 4

Embodiment Construction

[0037] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail: Figure 4 It is an exploded schematic view of the microwave oven door assembly of the present invention, Figure 5 It is a schematic diagram of the inner back of the door in the shielding structure of the microwave oven door of the present invention. As shown in the figure, the front of the door assembly is provided with a door panel 50, and a door handle 52 is formed on the front side end of the door panel 50 to facilitate opening and closing of the door.

[0038] A door glass 54 is attached to the door panel 50 . The door glass 54 can shield the through hole 50' on the door panel 50. This door glass 54 is transparent, and the inside of the barbecue cavity can be seen through the door glass 54 from the outside. A partition 56 is provided on the back of the door glass 54 .

[0039] The above-mentioned door panel 50 , door glass 54 , and partiti...

Abstract

The present invention discloses an electromagnetic wave shielding structure for microwave oven door. It includes door frame, edge-sealing face, door blocking component and door hook placed on one side end of door frame. The door frame is a frame of door combination body for closing front face of cooking cavity, the edge-sealing face is zigzag-formed on the edge of door frame for shielding electromagnetic wave outwards-leaked from door edge, and the blocking component also is combined in the edge of door frame. Said invention can effectively shield electromagnetic wave with different angles and various waveforms.

Description

technical field [0001] The invention relates to a microwave oven, in particular to an electromagnetic wave shielding structure for a microwave oven door. That is, an invention that can prevent the electromagnetic waves projected into the grill cavity from leaking out. Background technique [0002] A microwave oven is a device that uses microwaves of a certain wavelength to cook food. Such as figure 1 As shown, the microwave oven has a grill cavity 2, and a door 4 is installed at the opening of the grill cavity 2. The microwaves generated by the magnetron (not shown) are used to heat the food in the grill cavity 2 . At this time, the heated food should be heated evenly, but due to the characteristics of microwaves, it is difficult for the food to be heated evenly in a static state. [0003] Furthermore, when microwaves are used to heat food, the tray 6 on which the food is placed rotates so that the microwaves are evenly projected onto the food. [0004] In addition, a d...
