Embodiment 1

[0027] Without loss of generality, the first embodiment will be described by taking the microwave shielding plate 12 installed on the oven door 2 of the microwave cooking device as an example. It should be understood that the microwave shielding plate 12 of the first embodiment can also be applied to any other products requiring microwave shielding, and can be installed at any position of the products. Moreover, the microwave shielding plate 12 of the first embodiment can also be an independent product.

[0028] See figure 1 , the microwave cooking device of the first embodiment includes a furnace body 1 and a furnace door 2 .

[0029] For the structure of furnace door 2, please refer to figure 2 and image 3 . Among them, from image 3 It can be seen from the figure that the oven door 2 includes a microwave shielding plate 12 .

[0030] and, by image 3 It can be found that a protective cover 13 is provided on the outer side of the furnace door 2 (that is, the side aw...

Embodiment 2

[0059] The difference from the first embodiment is that the conductor of the second embodiment is continuously bent in a plane to form a spiral shape.

[0060] When the number of conductive layers is one layer and the conductor includes multiple sections of conductive coils, it is necessary to ensure that the gap between adjacent conductive coils of the conductor is not greater than 1 / 20 of the operating wavelength of the microwave cooking device, so as to ensure that the microwave shielding plate 12 shielding effectiveness.

[0061] Of course, when the adjacent conductive coils are arranged in close proximity, the shielding effect is the best at this time, and it can basically be ensured that there is no path that can directly pass through the conductive layer.

Abstract

The invention relates to the technical field of microwave shielding, and provides a microwave shield plate. The microwave shield plate comprises a plurality of conducting layers, the interiors of the conducting layers are correspondingly provided with conductors, and the two ends of each conductor are provided with wiring points, so that a shielding range covering the conducting layers is formed when the conductors are jointed into a conducting circuit. When the microwave shield plate is installed in a corresponding microwave cooking device, the conductors are jointed into the conducting circuit and form the shielding range covering the conducting layers. Once the microwave shield plate is damaged, the electric property of the conducting circuit can be changed, and leak of microwave can be detected timely only by detecting the changes of the electric property, so that whether shielding materials of a furnace door loose efficacy or not is responded objectively, the leak of the microwave is monitored accurately, start and stop of the microwave cooking device are controlled timely, and the risk caused by the leak of the microwave is reduced to a large extent.

Description

technical field [0001] The invention relates to the technical field of microwave shielding, in particular to a microwave shielding plate and a microwave cooking device. Background technique [0002] Taking a microwave oven as an example, metal mesh is used for microwave shielding in traditional microwave oven doors. When the metal mesh is used as a microwave shielding layer, the damage of the microwave shielding layer is relatively intuitive. With the application of visible microwave oven doors, microwave shielding layers that meet the visualization requirements have gradually appeared. Once these visible microwave shielding layers are damaged, they are not easy to be observed by the naked eye, which leads to microwave leakage in the microwave cooking device after the microwave shielding layer is damaged. . Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] One o...
