A solar photovoltaic microwave oven

Abstract

The invention discloses a solar photovoltaic microwave oven. The microwave oven comprises a thin film cell sun umbrella for transforming optical energy into electricity, a charging protection circuit connected with the thin film cell sun umbrella, a lithium battery having an over-discharge protection function and connected with the charging protection circuit, and a direct current microwave oven. The lithium battery is in line connection with the direct current microwave oven. The microwave oven realizes the function of power maximizing and reduces energy consumption. Meanwhile, the microwave oven is convenient for a user to carry and use and is particularly suitable for motorist which broadens the application space of the microwave oven. The solar photovoltaic microwave oven of the invention can be used outdoor independently of electric supply, such as motor home leisure tourism, etc., and improve the living standards. The microwave oven can supply power to conventional electric appliance such as a laptop via an external sine wave inverter. Moreover, the built-in lithium battery can be detached quickly for automobile emergency start.

Description

technical field [0001] The invention relates to the field of energy saving and environmental protection, in particular to a solar photovoltaic microwave oven. Background technique [0002] Microwave oven is a kind of common household electrical appliance, is the modern cooking stove that heats food with microwave. The power supply provides a high voltage of about 4000 volts to the magnetron. Under the excitation of the power supply, the magnetron continuously generates microwaves, and then couples into the cooking cavity through the waveguide system. Near the entrance of the cooking cavity, there is a rotatable stirrer, because the stirrer is a fan-shaped metal, which can reflect the microwave in all directions after rotating, so it can evenly distribute the microwave energy in the cooking cavity, thus Reheat food. [0003] Microwave ovens in the prior art generally only have a mains power interface, and existing microwave oven products or patents do not have the predictio...
