Description

gas burner

technical field

The utility model relates to a burner used on a frying stove.

Background technique

Existing gas burners used on frying stoves include a combustion head seat with a combustion head in the inner cavity, a furnace ring is fixed on the combustion head seat, and the air is forced to be blown by a blower to achieve the purpose of burning. The gas burner with the above structure has poor gas atomization effect and insufficient combustion, and part of the gas flows away with the high-temperature flame, which not only pollutes the environment, but also causes waste of gas. In addition, when the gas flows away, part of the heat also flows away, resulting in low thermal efficiency.

Utility model content

The technical problem to be solved by the utility model is to provide a gas burner with sufficient gas combustion and high thermal efficiency for the above shortcomings.

In order to solve the above technical problems, the utility model provides a gas burner with the following structure, including a combustion head seat with a combustion head installed in the inner cavity, and a furnace ring is fixed on the combustion head seat. Its structural features are: the combustion The head is densely covered with ventilation holes, the combustion head seat is a sandwich structure composed of the inner wall and the outer wall. There is an air inlet connected to the air inlet channel, and an air inlet hole connected to the air inlet channel is provided on the inner wall; the furnace ring is a sandwich structure composed of an inner ring wall and an outer ring wall, and the inner ring wall and the outer ring The space between the walls is the return air passage, the upper part of the inner ring wall is provided with a return air hole, and the lower part of the outer ring wall is provided with an exhaust hole, and the return air hole and the exhaust air hole are connected with the return air passage.

For the gas burner with the above-mentioned structure, the shape of the bottom of the frying pan used should match the opening of the hob. The combustion process is as follows: the gas flows out through the gas outlet hole on the combustion head, and the blower blows the gas through the air inlet channel and the air inlet hole. The air is sent in and fully mixed with the gas, so that the gas can be better atomized, and the gas fully mixed with the air and atomized can be fully burned in the combustion chamber surrounded by the furnace ring; in addition, the long flame and the The high-temperature mixed gas, blocked by the wok, enters the return air channel through the return air hole, and a small part of the unburned gas is further burned in the return air channel. The heat generated by the combustion and the heat carried by the high-temperature mixed gas Return to the combustion chamber through the inner ring wall to keep the combustion chamber at a high temperature, and the exhaust gas after combustion is discharged from the exhaust hole.

It is not difficult to conclude from the above description that the utility model has the advantages of sufficient gas combustion and high thermal efficiency.

In order to make the air and gas mix uniformly, the center line of the air inlet hole is inclined relative to the surface of the inner wall.

In order to make the air and gas mix more evenly, the air inlet holes are arranged around the inner wall and divided into three circles along the inner wall from top to bottom. The upper circle of air inlet holes has the same inclination direction in the horizontal direction, and the lower two circles of air inlet holes have the same inclination direction in the vertical direction.

For the convenience of igniting gas at any time, an open flame pipe is connected to the combustion head seat.
