Empty-burning and dry-burning prevention control device of gas stove and gas stove

Abstract

The invention discloses an empty-burning and dry-burning prevention control device of a gas stove. The device comprises a non-contact type gas stove temperature acquisition module, a timing control module and an alarm module, wherein the non-contact type gas stove temperature acquisition module is used for acquiring temperature information within the range of the gas stove; the timing control module is used for controlling and connecting a gas supply valve of the gas stove, acquiring the temperature information and timing, and controlling the gas supply valve of the gas stove to be closed whena preset temperature threshold range is reached and duration reaches preset timing duration; and the alarm module is used for receiving an instruction of the timing control module and sending out a warning signal when the preset temperature threshold range is reached and the duration reaches the preset timing duration. According to the device and the gas stove, the safe cooking, empty burning anddry burning states of the gas stove can be identified according to monitoring temperature data, and the gas supply valve is controlled to be cut off when empty burning and dry burning are judged on the basis of timing configuration, so that the purpose of safely controlling the use of the gas stove is achieved; and meanwhile, a mode configuration function is achieved, use timing and temperature adjustment of the gas stove are achieved according to the cooking purpose, intelligence is achieved, and the automatic control degree is high.

Description

technical field [0001] The invention relates to the technical field of gas cooker safety control, in particular to a gas cooker air defense and dry burning control device and a gas cooker. Background technique [0002] With the implementation of the country's "coal to gas", gas stoves have become the first choice for every household to cook; but at the same time, the use of gas stoves will also be accompanied by many dangerous incidents, so it is necessary to prevent dry burning gas stoves pregnancy. [0003] The traditional anti-dry gas stove is equipped with a thermistor sensor on the stove head, which can detect the temperature of the bottom of the pot, and automatically stop the gas and turn off the flame when it exceeds the preset value; or use the front-mounted gas stove timing valve to force timing To achieve regular turn off to prevent dry burning. Its disadvantages are as follows: [0004] 1. The thermistor sensor installed on the stove needs to be extremely high...

AI Technical Summary

Problems solved by technology

[0004] 1. The thermistor sensor installed on the stove needs to be extremely high temperature resistant in the flame, and the cost is high;

[0005] 2. For gas stoves with mandatory timing, first of all, dry burning cannot be detected when no one is looking after them;

[0007] Therefore, the traditional anti-dry burning gas stove can not fully realize the purpose of air-proof burning and dry burning, and the use effect is not ideal.
