Thermoelectric power generation stove power supply system and charging management method thereof

Abstract

The invention provides a thermoelectric power generation stove power supply system and a charging management method thereof, the system comprises a stove main body, the stove main body is provided with a thermoelectric power generation unit, a battery box for power supply ignition, a charging management module connected with the temperature difference power generation unit and the battery box, anda pulse ignition module connected with the battery box; the temperature difference power generation unit is installed on a temperature rise component of a gas stove body and used for converting heatenergy into electric energy according to a temperature difference signal of the temperature rise component and charging the battery box through the generated electric energy, and the charging management module is used for controlling forward charging of the battery box and controlling the thermoelectric power generation unit to stop working or cut off a charging loop when the battery box is detected to be fully charged. The method provided by the invention adopts the system to carry out charging management. The heat released in the combustion process of the gas stove is used for charging, a battery does not need to be replaced frequently, the recycling can be achieved, and the use safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of household gas cookers, in particular to a cooker power supply system for thermoelectric power generation and a charging management method applied to the system. Background technique [0002] Thermoelectric power generation is based on the Seebeck effect to directly convert heat energy into electrical energy. Semiconductor thermoelectric power generation chips have the advantages of no noise, no pollution, no wear, light weight, and long service life. They can be used in the recovery and utilization of various waste heat. However, for a long time, due to the constraints of thermoelectric conversion efficiency and cost constraints, thermoelectric power generation technology has been mainly used in cutting-edge fields such as aerospace and military affairs. In recent years, the emergence of a batch of high-performance thermoelectric conversion materials has provided the possibility for the application of the...

Problems solved by technology

Due to the short life of dry batteries or alkaline batteries, the batteries need to be replaced frequently, which is not convenient for users to use

At the same time, during the combustion process of the gas stove, a large amount of heat is released, and about 40% of the heat is taken away by the flue gas and directly wasted by heat dissipation.

[0004] In addition, the battery power is limited, so when the gas stove is used for a period of time, when the battery power is lower than a certain value, the gas stove ignition and other functions will not work normally, so users need to frequently replace the battery during the use of the gas stove. Increase the cost of use, on the other hand, improper recycling of replaced batteries will also cause pollution to the environment, so it is very necessary to improve the power supply structure of gas stoves
