Abstract

A solar microwave oven comprises a storage battery which provides power for magnetron of the microwave oven. The storage battery is connected with a solar cell panel through a solar power supply controller. The solar power supply controller is electrically connected with the magnetron through a driving circuit. The solar cell panel and the storage battery are arranged on the microwave oven. The solar cell panel and the storage battery of the solar microwave oven of the invention are arranged on the microwave oven. A user can conveniently install the solar cell panel and the storage battery. An extra lead does not need to be connected. When the microwave oven does not work, a current generated by the solar cell panel can be stored in the storage battery. When the microwave oven works, the storage battery power can be used preferentially. Besides, in order to avoid a situation that a microwave oven load can not be satisfied because the solar cell output power is not enough, an electric supply is added. A solar cell panel circuit and an electric supply circuit form a parallel circuit so as to realize direct current side grid connection. A structure is simple and reasonable. Energy saving, low carbon and environmental protection can be achieved. Usage is convenient. An energy efficiency ratio is high. An application range is wide.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a solar microwave oven. Background technique [0002] At present, with the high efficiency and convenience of microwave ovens, their promotion has become more and more widespread, and they have entered different consumer fields: household, commercial, and medical. Microwave ovens are generally powered by municipal electricity. As we all know, the supply of municipal electricity generally depends on hydroelectric power generation and coal-fired power generation, which wastes a lot of natural energy and brings a lot of pollution to the environment. [0003] Chinese Patent Document No. CN101922748A disclosed on December 22, 2010 a microwave oven using a solar photovoltaic power generation system as a power supply. Sunlight irradiates solar cells to generate direct current. spare. When the switch of the microwave oven is turned on, the DC input inverter is converted into AC power, and the AC pow...
