An Intelligently Controlled Microwave Heater

Abstract

The invention discloses an intelligent control microwave heater comprising a heater body and an intelligent control device. The heater body comprises a microwave generator, a microwave heating cavity and heat conducting medium; the intelligent control device comprises a control circuit, a negative temperature coefficient thermistor, a power supply, an electronic switch and an external power supply; the control circuit, the negative temperature coefficient thermistor and the power supply form an enclosure circuit; the control circuit comprises a current measuring module, a counting module and a control module; the current measuring module is used for measuring the current of the enclosure circuit, the counting module is used for counting the number of the current, measured by the current measuring module, meeting a preset threshold, and the control module is used for controlling the electronic switch to switch off when the preset number is achieved according to the counting module. According to the heater, the microwave heating manner is adopted, and the heating efficiency is higher as compared with that of the traditional resistor heating manner; by means of the intelligent control device, the problem of electrical heater circular heating caused by forgetting for unattended situation is solved effectively, and the consumption of the electrical heater due to circular heating is avoided.

Description

technical field [0001] The invention relates to an electric heater, in particular to an intelligently controlled microwave heater. Background technique [0002] Energy shortage has become an important problem restricting my country's economic development. Coal accounts for 66% of the current primary energy consumption in my country. At present, the dominant heating method in my country is still coal-based centralized heating. In the annual coal consumption, heating coal consumption accounts for nearly half. Resources, such as coal resources, water resources, and heat energy lost in the transmission process, followed by environmental pollution. Therefore, innovating heating methods and adopting new heat sources are of great significance for reducing energy consumption, protecting the environment, and building a conservation-oriented society. [0003] Electric heater is an internationally popular high-quality and long-life electric heating equipment, which is the process of ...

Problems solved by technology

[0004] However, the heating of the resistance heater is the most primitive, so the thermal efficiency is also the worst. Usually, the thermal efficiency is only about 70%, and a large amount of heat energy is dissipated into the air.

At the same time, the existing electric heaters can automatically cut off the circuit to stop heating when the temperature reaches a certain temperature, and can restart heating when the temperature is lower than a certain temperature. However, because the heating time of the electric heater is too long, people often Forget about the electric heater that is heating, which will cause the temperature of the electric heater to drop for a period of time after heating, and it will be reheated again, which will consume electric energy and shorten the service life of the electric heater, and there will be safety hazards such as fire
