Overheating air-burn preventing device of gas stove and preventing method

Abstract

The invention discloses an overheating air-burn preventing device of a gas stove and a preventing method. The overheating air-burn preventing device comprises a temperature sensor, a temperature sensor control circuit, a singlechip microprocessor, a main solenoid valve and a main solenoid valve control circuit, wherein the temperature sensor is used for detecting the temperature of the bottom of a cooker; the main solenoid valve and the main solenoid valve control circuit are arranged on a main gas pipe; in addition to the traditional low-temperature flameout defensive function, the device adds intelligent high temperature protection, has sensitive sense to the cooker temperature, prevents the air burn by overheating detection and overheating curve judgment so as to achieve the effect of preventing the air burn of majority of cookers, thereby effectively preventing fire accidents caused by abnormal high temperature of the air burn of the cooker, and protecting family property and personal safety all the way. The invention has high precision, simple and stable system and relative low cost and can meet the requirement of people on using the gas stove.

Description

Technical field [0001] The invention relates to a gas stove overheating anti-air burning device based on a single-chip microprocessor intelligent control and a control method thereof. Background technique [0002] Gas stoves are very popular in household use. At present, most of the gas stoves produced on the market use mechanical means to control the gas, and the main purpose is to overcome the midway flameout and shut down. There is no device and method for preventing overheating and air burning with a single-chip microprocessor intelligently. , It is more difficult to protect the safety of users. Summary of the invention [0003] In order to overcome the above shortcomings, the present invention provides a gas stove overheating and empty burning prevention device and method. The device and method not only have the traditional low temperature flameout protection function, but also add intelligent high temperature protection through overheat detection and overheat curve. Discrim...
