Embodiment Construction

[0036] The core of the present invention is to provide a tempering gas stove, so that there is as little gas as possible in the burner and pipeline, so as to eliminate or reduce the occurrence of tempering phenomenon.

[0037] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] Please refer to figure 2 and image 3 , figure 2 It is a schematic diagram of the state of the switch mechanism disclosed in the embodiment of the present invention when the burner is blocked, image 3 It is a schematic diagram of the state of the switching device disclosed in the embodiment of the present invention when the furnace head is opened.

[0039] The anti-backlash gas stove provided by the embodiment of the present invention includes sequentially connected nozzles, a burner 8 and a burner. In a...

Abstract

The invention relates to an anti-backfire gas stove. The anti-backfire gas stove comprises a nozzle, a furnace end and a burner which are sequentially connected. The anti-backfire gas stove further comprises a switching mechanism which is arranged inside the furnace end and can block and open a gas channel inside the furnace end. When the gas stove is closed, the switching mechanism can block the gas channel inside the furnace end. Due to the fact that the switching mechanism is arranged inside the furnace end, the furnace end is directly connected with the burner, the residual gas volume is greatly lowered, the probability that mixing ratio of gas to air is within the explosion limit is greatly lowered, a small amount of gas remained in the furnace end and the burner can be burned by a flame, the flame cannot be spread towards the furnace end or farther, the continuous flameout noise and even the explosive sound due to the fact that the flame is spread for the long time are avoided, and parts of the gas stove is effectively protected from being damaged.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to a backfire-proof gas stove. Background technique [0002] Current gas stoves often make a "bang" sound when they are turned off, which is the flameout noise. When the flame is turned off, it is often accompanied by bangs or noises. The heat generated by this kind of combustion not only cannot be used, but may even cause accidents. This is a common phenomenon in tempering. The tempering phenomenon is harmful to the burner and the entire gas Stoves will have destructive effects, which may seriously cause people's property loss or even endanger people's life safety, so the occurrence of tempering should be avoided as much as possible. [0003] The study found that the backfire is due to the continuous decrease of the flow rate of the mixed gas entering the burner, that is, the continuous decrease of the airflow velocity. Finally, because the airflow velocity is lower than ...
