Lighting device for microwave oven

Abstract

The invention discloses a lighting device of a microwave oven, and comprises a passive light emitter (100), which is a seal shell. The passive light emitter (100) is combined with the interior wall of a microwave oven body and consists of a base layer, a coating layer, an isolation layer and a surface layer. The base layer and the surface layer are the transparent organic plastics. The interior surface of the base layer is coated with sulfur and selenium. A method of point-contacting is used for bonding of the base layer and the surface layer, and the parts, which are not bonded, are filled with gas or liquid. The beneficial effect is that as a small part of microwaves inside the microwave oven can be converted into the light energy of visible waves when a magnetic control tube of the microwave oven is in operation, the light source will not emit light in the case of no microwave emission; the method can meet the lighting requirement by the microwave oven, saves energy and increase the product satisfaction degree of a user.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a lighting device for a cooking chamber of a microwave oven which converts microwave energy into light energy. Background technique [0002] Generally speaking, a microwave oven is a kind of microwave oven that puts food inside it, seals it, turns on the power of the magnetron to make it generate high-frequency microwaves, and irradiates the high-frequency microwaves to the food through the waveguide to make the water in the food Molecules vibrate approximately 2.45 billion times per second, and household appliances that cook and heat food through the frictional heat generated between water molecules. To facilitate operation, the cooking chamber of the microwave oven is equipped with lighting. [0003] The lighting devices of existing microwave ovens generally use point light sources. The bulbs are arranged outside the cavity of the microwave oven to protect the bulbs, and illuminate the insi...

Problems solved by technology

[0005] But the lighting device of above-mentioned existing microwave oven has the following disadvantages: the light transmittance and brightness of light bulbs are fixed, the irradiation range is fixed, and the light bulbs are energy-consuming devices.

[0006] Microwave ovens use magnetron lighting to produce an ornamental open light source with high energy consumption. Due to the high shielding requirements of microwave ovens, the microwave leakage standard should be within 0.5M, which is difficult for magnetron lighting to meet Require
