specific Embodiment 1

[0022] Specific embodiment 1: The electrical appliance is a microwave oven, including an outer box, an inner box, a door, a sensor, a magnetron, a waveguide, a control unit, etc., and the right inner side box is a window-shaped mica sheet with a wave-transmitting structure for electromagnetic waves to pass through surface, the wave-transparent structure can be bonded to the surface of the mica sheet, or it can be compounded into the mica sheet. The shape of the microwave waveguide outlet is circular, and the microwave waveguide outlet is facing the electromagnetic wave passing surface; The wavelength is 30.612mm. Different wave-transmitting structures are pre-distributed in the two areas of the window-shaped mica sheet. There is a smooth rack on one side of the stainless steel plate, and a groove-shaped slideway on the other opposite side. There is a motor in the upper right inner side of the box. It can drive the smooth tooth shape matched with the rack. After distribution acc...

specific Embodiment 2

[0023] Specific embodiment 2: The electrical appliance is a barbecue microwave oven, including an outer box, an inner box, a door, a sensor, a magnetron, a waveguide, a resistance heating tube, a control unit, etc., the shape of the microwave waveguide outlet is rectangular, and the side of the microwave waveguide outlet is opposite to the The electromagnetic wave passing surface; the right inner side of the box is a window-shaped electromagnetic wave passing surface with a wave-transparent stainless steel plate. The electromagnetic wavelength is 122.4489795mm, and the quarter wavelength is 30.612mm. First, the wave-transparent stainless steel plate is selected by bimetal The stainless steel plate has at least one pair of opposite sides with groove-shaped slides. When the temperature in the cooking room rises to the design temperature, the stainless steel plate bulges inwards to change the distribution shape of the electromagnetic wave passing through the original electromagneti...

Abstract

The invention relates to a variable electromagnetic wave acting surface forming method. An electromagnetic wave acting surface comprises an electromagnetic wave reflecting surface and an electromagnetic wave passing surface. The variable electromagnetic wave acting surface forming method is mainly characterized in that at least one electromagnetic wave acting surface in an adopted electric appliance is provided with a variable structure, and after the position or shape of the electromagnetic wave acting surface changes, propagation of electromagnetic waves making contact with the electromagnetic wave acting surface changes in the electric appliance. The invention further provides the electric appliance adopting the variable electromagnetic wave acting surface forming method.

Description

technical field [0001] The invention relates to a method for electromagnetic wave control and an electrical appliance using the method, in particular to an electrical appliance with a variable electromagnetic wave action surface.
