Embodiment Construction

[0035] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0036] For microwave ovens in the prior art, such as image 3 As shown, the microwave generator is composed of a transformer 2, a booster circuit 3 (the booster circuit is composed of a high-voltage capacitor 13 and a high-voltage diode 14 connected in series) and a magnetron 4 . Magnetron 4 is a kind of electric vacuum device used to generate microwave energy, and it is made up of tube core and magnetic copper (or electromagnet), and the structure of tube core includes cathode (or filament) 5, anode 6, energy exporter ( not shown) and the magnetic circuit system (not shown), the transformer 2 and the booster circuit 3 provide the energy required for the magnet...

Abstract

The invention relates to the field of household appliances, and discloses a microwave generator and a microwave oven. The microwave generator comprises multiple magnetrons for outputting microwaves, apower device, and multiple first switch devices, wherein the power device is used for providing different voltages to a cathode and an anode of each magnetron; and each first switch device is correspondingly arranged in a power supply loop of the cathode of the corresponding magnetron and is used for controlling the corresponding magnetron to output the microwave. The microwave generator is simplified in inner structure, high in space occupation rate and low in production cost.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a microwave generator and a microwave oven. Background technique [0002] A microwave oven is a cooking appliance that uses food to absorb microwave energy in a microwave field to heat itself. Microwave generator systems for existing household microwave ovens, such as figure 1 As shown, the transformer / inverter 2, the booster circuit 3 and the magnetron 4 are combined to form a microwave generator, and the computer board 1 is mainly used to control the microwave generator to work or shut down. The output power of household microwave ovens is not large, usually between 700W and 1300W. [0003] With the acceleration of people's life rhythm, a high-power microwave oven is needed in commercial kitchens, that is, a commercial microwave oven. It has the characteristics of fast cooking speed, less food nutrient loss, no open fire and oily smoke, and good secondary heating effect. I...
