Combustor

Abstract

The invention relates to a combustor which comprises a base and a fire cover arranged at the top of the base, a gas mixing cavity is defined by the fire cover and the base, a fire hole in the fire cover communicates with the gas mixing cavity, and the base is further connected with a light detection assembly capable of detecting the light condition in the gas mixing cavity. According to the combustor, the light condition in the gas mixing chamber can be detected through a pipeline detection assembly; if tempering occurs, the light detection assembly can obtain a tempering detection result at the first time when the flame just enters the gas mixing cavity, then the gas valve is controlled to be closed, the response speed of tempering detection is greatly increased, and the combustor is safer to use. Besides, the light detection assembly can also judge whether the fire cover is already placed or not by detecting the light condition in the gas mixing cavity, so that the use safety of thecombustor is greatly improved, and the situation caused by lack of the fire cover is avoided.

Description

technical field [0001] The invention relates to a device with a burner. Background technique [0002] During the actual use of the gas stove, if the composition of the gas source is abnormal, the pressure of the gas source is abnormal, or the damper is too large, it will cause the flame to spread to the inside of the burner, and then cause the gas to burn inside the burner. The phenomenon not only causes damage to the structure and life of the burner, but also has potential safety hazards. On the other hand, after the user has cleaned the gas stove, there are situations where the user forgets to place the fire cover or does not place it in place. In this case, the ignition operation will lead to problems such as abnormal flame state and backfiring, which will also cause damage to the burner structure. deformed and presents a safety hazard. [0003] The traditional anti-tempering is achieved by detecting the temperature near the injection pipe and the nozzle through a therm...

AI Technical Summary

Problems solved by technology

However, the disadvantage of this technical solution is that only when the flame enters the burner from the fire hole of the fire cover and spreads to the nozzle opening to form a stable combustion, and then causes the temperature near the nozzle or the injection pipe to exceed the set temperature value, can it be effectively identified In the case of tempering and the cut-off work of the solenoid valve, the corresponding time for the cut-off of the solenoid valve is relatively long

[0004] There is no detection of the placement of the fire cover in the prior art, but when the cooker is in use, the absence of the fire cover will cause the following problems: first, deflagration will occur at the moment of ignition, and the flame will be very long, which will frighten the user; second, the flame will be abnormal , the entire flame is ejected from the base or the gas mixing chamber, and then burns directly, which will deform the aluminum base and damage the entire burner; third, it is very easy to cause backfire, the flame burns inside the burner, causing damage to the burner , glass panels thermally shatter, which in turn may cause safety issues

However, the cooker temperature detection device with this structure often needs to extend upwards to the position where the cooker can touch, and the appearance is not beautiful. At the same time, the detection cannot be realized due to the change of the shape and size of the cooker.
