Problems solved by technology

[0002] The gas burner generally includes an injection tube and a fire distribution seat. After the gas passes through the injection tube for a short time, it enters the fire distribution seat to participate in combustion. Since the time for the gas to pass through the injection tube is short, the time for gas and air to mix is ​​short. If it enters the fire distribution seat to participate in the combustion without sufficient mixing, the mixture of gas and air will not burn sufficiently, which will affect the overall combustion efficiency of the gas furnace, and it will easily produce a large amount of harmful gases such as carbon monoxide during combustion.

[0040] see Figure 4 , Figure 5 The difference between this embodiment and the first embodiment is that the sealing connection structure of the fully gas-mixed gas furnace includes a sealing ring 17 and an air inlet 152 arranged on the three-way seat 15, and the air inlet 152 is provided with a connection The step 153, the sealing ring 17 and the connecting step 153 cooperate with each other, the sealing ring 17 and the air inlet nozzle 152 are tightly connected with the air inlet 16 respectively, and the sealing ring 17 can ensure the sealing between the tee seat 15 and the air inlet 16 , the two do not need to be fixed by welding, therefore, the materials of the two can be different, which improves the flexibility of production and processing.

[0041] The rest of the undescribed parts are the same as those of the first embodiment and will not be repeated here.

Abstract

The invention relates to a gas furnace capable of fully mixing gas. The gas furnace comprises an injection pipe and a fire distribution seat, the fire distribution seat is provided with a fire distribution cavity correspondingly communicating with the injection pipe, the injection pipe is provided with a gas premixing cavity, a secondary gas mixing cavity and a gas outlet cavity, the gas premixing cavity is provided with a gas inlet, the gas outlet cavity communicates with the fire distribution cavity, and the secondary gas mixing cavity 12 is connected with the intersection position of the gas premixing cavity 11 and the gas outlet cavity 13; and the secondary gas mixing cavity correspondingly communicate with the gas premixing cavity and the gas outlet cavity, part of mixed gas of fuel gas and air passing through the gas premixing cavity enters the secondary gas mixing cavity before entering the gas outlet cavity, the mixed gas turns back towards the gas premixing cavity after reaching the end of the secondary gas mixing cavity and continues to collide with the mixed gas moving towards the secondary gas mixing cavity, the gas mixing time of the gas and the air is prolonged, the gas and air mixing effect is further improved, so that the overall combustion efficiency of the gas furnace is improved, and the content of harmful gas generated during combustion is reduced.

Description

technical field [0001] The invention relates to the technical field of gas equipment, in particular to a gas furnace with sufficient gas mixture. Background technique [0002] The gas burner generally includes an injection tube and a fire distribution seat. After the gas passes through the injection tube for a short time, it enters the fire distribution seat to participate in combustion. Since the time for the gas to pass through the injection tube is short, the time for gas and air to mix is ​​short. If it enters the fire distribution seat to participate in combustion without sufficient mixing, the mixture of gas and air will not burn sufficiently, which will affect the overall combustion efficiency of the gas furnace, and will easily produce a large amount of harmful gases such as carbon monoxide during combustion. [0003] Therefore, further improvements are required. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcoming...
