Gas stove and method for controlling gas stove glass disc temperature

Abstract

The inventive gas stove comprises a stove door in which air-gas mixture is burning, a dog mounted in the upper part of the stove door, a stove frame firm-jointed with the fire door for fastening the stove edge, a glass disk mounted in the upper part of the frame for putting heated objects, a temperature sensor set on the lower surface of the glass disk for measuring the temperature of the glass disk and a microcomputer for controlling the rotation rate of the air supply fan according to the temperature sensed by the temperature sensor.

Description

technical field [0001] The invention relates to a gas furnace, in particular to a glass pan temperature control device and a glass pan temperature control method for the gas furnace. Background technique [0002] Generally speaking, a gas furnace is a burner that burns a mixture of fuel and air, uses the radiant energy generated when the radiant is heated, and cooks the heated object. [0003] The gas furnace of prior art is described below in conjunction with accompanying drawing. [0004] Such as figure 1 and figure 2 As shown, the gas furnace of the prior art includes: a mixing tube (1) for conveying the mixed gas of air and gas; a furnace mouth (2) connecting the mixing pipe (1) and providing a combustion space for the mixed gas; being installed in the furnace mouth ( 2) a furnace mat (3) that can be burned red by the burning mixed gas on the upper installation part (2a); a bonding pad (4) that is installed on the upper part of the furnace mat (3) and is used to adju...

AI Technical Summary

Problems solved by technology

[0011] However, the prior art gas furnace with the above-mentioned structure cannot be controlled when the temperature of the glass plate (6) rises above the reference value because it operates at a specified air-fuel ratio, and the glass plate (6) may overheat. Phenomenon

like image 3 As shown, for a gas furnace working at a specified air-fuel ratio, the temperature of the glass plate rises in direct proportion to the working time. The longer the working time, the higher the temperature of the glass plate (6). In the case of frequent overheating, it will shorten Service life of the glass disc (6)

[0012] In addition, when the temperature of the glass disc (6) exceeds the reference value, the heat lost through the glass disc (6) will increase, which will increase the indoor temperature and increase the concentration of carbon monoxide in the exhaust gas.

[0013] Especially when the user finishes cooking the object to be heated and removes the object to be heated from the glass dish, if he forgets to turn off the gas stove, the temperature of the glass dish (6) in the no-load state will be very high in the state of burning for a long time. High, so there is a risk of explosion
