Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a gas burner used in gas stoves and the like.

A gas burner has a combustion tube cut out from a wire mesh and a glass tube arranged around it, and since the space between the two tubes is used as a flow path for secondary air, the combustion tube near the inlet side has a cooling effect due to the secondary air.
Red heat is inhibited.

Therefore, when viewed through the glass cylinder, although the upper part of the combustion cylinder is sufficiently red hot, the lower part is insufficiently red hot, resulting in uneven red heat.

The present invention has been developed in view of the above points, and embodiments thereof will be described below with reference to the drawings.

Reference numeral 1 denotes a combustion cylinder made by winding a wire mesh made of heat-resistant wire into a cylindrical shape and standing it up.The upper opening is welded and fixed to a cover plate-like closing cap 2, and the lower opening is attached to a mounting cylinder 4 with a flange 3. It is welded and fixed in the open state.

Reference numeral 5 denotes a base plate on which the collar 3 of the mounting tube 4 is placed and fixed, and a connection port 6 that projects downward and opens in the center facing the opening of the attachment tube 4 and the lower opening of the combustion tube 1 is a base plate. At the same time, this connecting port 6 is reduced in diameter downward and is connected and fixed to the mixing pipe 7.

8 is a gas nozzle facing the lower end opening of the mixing tube 7.

Reference numeral 9 denotes a heat-resistant glass tube that is fixed upright over the outer periphery of the closing cap 2 and the base plate 5, and is connected to the combustion tube 1.
A secondary air circulation interval 10 is provided between the two.

11...... is the flow interval 1 drilled in the base plate 5.
0, 12, . . . are the outlets of the flow gap 10 drilled in the closure cap 3.

Reference numeral 13 denotes an annular guide plate fixed upright on the inner periphery of the inlet 11 between the lower part of the combustion tube 1 and the inlet, and its height is approximately the same as that of the mounting tube 4. .

Note that this guide plate 13 may be inclined outward.

14 is a flow regulator fixed to the inner surface of the connection port 6;
This is done so that the mixed gas in the room is approximately even between the top and bottom.

In this way, when gas is supplied from the gas nozzle 8, air is sucked by the ejector effect, and the mixed gas flows through the rectifier 14.
The fuel is rectified and supplied to the entire area of the combustion tube 1 almost uniformly, and then combusted.

During this combustion, the secondary air rising within the flow interval 10 is sequentially used, and the combustion exhaust gas is discharged from the outlets 12.

At this time, the air entering the circulation interval 10 from the inlet 11 is guided upward by the guide plate 13,
Further, during combustion, a draft effect also occurs, resulting in a strong rise.

At the same time, the guide plate 13 suppresses the supply to the lower part of the combustion tube 1.

That is, the secondary air is supplied while being diffused little by little from above the guide plate 13 within the flow interval 10, and is not concentrated in the lower part of the combustion tube 1.

Furthermore, when the guide plate 13 is tilted outward (towards the glass tube), the secondary air collides with the glass tube 9 and is then diffused and supplied, so that the secondary air is not concentrated in any part of the combustion tube 1. does not occur and is more effective.

In this way, the gas burner of the present invention provides a secondary air circulation interval between the hot smoking cylinder and the glass cylinder, and also has a guide plate standing between the lower part of the combustion cylinder and the inlet around the inlet. It is possible to prevent the secondary air that enters from concentrating at the bottom of the combustion cylinder, and also to diffuse it above the guide plate.
It is possible to supply secondary air to almost the entire area of the combustion tube without concentrating it, thereby eliminating uneven red heat.
