Double-fireproof cover, air window furnace end, double-display panel and blast gas stove

Abstract

The invention discloses a double-fireproof cover, an air window furnace end, a double-display panel and a blast gas stove, and relates to gas stoves and main components thereof. According to an existing fire cover, fire return is liable to occur due to a large fire hole, flame deviation is liable to occur due to a small fire hole, balance can only be sought between the two conditions, and therefore safety margins are not high. According to the fire cover, a ventilation flame-retardant piece is adopted to thoroughly block fire return of a fire hole, the flame-deviation-preventing large fire hole is adopted to enable the gas flow speed of the fire hole to be always lower than the combustion diffusion speed, and high-stability combustion of the fire hole without fire return and flame deviation is achieved. According to an existing multi-injection-pipe cast aluminum furnace end, a middle combustion area only depends on air duct air suction for combustion supporting, and therefore oxygen deficit of different degrees becomes a common problem. According to the air window furnace end, a central air window is adopted to directly supply oxygen to the middle combustion area, and the problem of oxygen deficit in the middle of the furnace end is thoroughly solved. An existing stove panel is single in display, the stove panel is provided with an inclined embedded liquid crystal panel, a light window is additionally arranged, and a man-machine interaction interface is optimized. An existing blast gas stove is single in air effect function, and the blast gas stove adopts interference blastand large circulation of an air overflow opening to form an ecological environment for promoting combustion and guaranteeing safety.

Description

technical field [0001] The present invention relates to a gas cooker part and a gas cooker, in particular to a burner head that does not temper and does not separate from the fireworks cover, does not lack oxygen, does not leak water, does not temper and does not leave the flame, a windshield burner head, an interference blowing ecological gas cooker casing, and a mixed dual-display gas burner. Stove panels, and gas stoves / integrated stoves using the above technologies. Background technique [0002] The existing atmospheric burner is the mainstream configuration of gas stoves today. Among them, the performance of the key fire cover and burner plate basically determines the advantages and disadvantages of the thermal parameters of the gas stove. [0003] 1. The flame cover burner of the burner is mainly a round hole burner and a slit burner. The cross-section, depth, and interval of the crater are all limited by atmospheric combustion conditions, and it is difficult to make...

AI Technical Summary

Problems solved by technology

[0004] 1. The size of the cross-section of the existing burner is not only to prevent tempering due to low flow rate of small flow rate, but also to prevent flame separation caused by high flow rate of large flow rate. Even so, the margin of safety is not high

[0005] 2. In order to prevent the burner from flame/flame off, in recent years, the method of increasing the flame stabilization burner has been adopted to stabilize the main flame, which has almost become the only means of stabilizing the flame, but this method is ineffective in preventing the burner from backfiring

[0007] 4. The larger outflow static pressure of the furnace head will prevent the ejector tube from sucking in more air, which is not conducive to combustion

[0008] 5. In the case of being unable to break through the limitations of the current burner, some functions that require the cooperation of the burner will be restricted

[0015] f. The general direction of the fire cover concept is very correct and reasonable. Unfortunately, the specific technical measures are not in place, and the vision of preventing backfire, promoting safety, and improving thermal efficiency has not been fully realized, so there is still room for improvement

[0016] 2. There is an embarrassment in today's stoves/burners, that is, the stove head with good secondary air ventilation is good for combustion, but it is not waterproof, and the stove head with good waterproof is good for cleaning, but it is not good for ventilation and bad for combustion

Especially in recent years, the cast aluminum burner plate with a large base plate of the burner has emerged in recent years. The waterproof effect is very good and has become the mainstream today. However, the large base plate of the burner blocks the vertical ventilation from top to bottom, and the central combusti
