JP3061372U - Burner for gas stove - Google Patents

Abstract

(57) [Summary] An object of the present invention is to improve the structure of a burner head of a portable gas stove. The present invention comprises a burner head (6) installed at the top end of a mixing tube (3), and an inclined surface (7) protruding inward around the upper surface of the burner head (6).

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a burner used for a portable gas stove.

[0002]

[Prior art]

 Conventionally, in a portable gas stove, a member called an inner cup a as shown in FIG. 1 has been used for a head of a burner portion, so that a flow path of a mixed gas can be lengthened and a direction change can be performed. In addition, those that reduce the flow velocity of gas, prevent ejection of unburned gas, and achieve complete combustion of gas have become widespread.

[0003] However, the production cost has been high because a process of drawing an independent part called the inner cup and welding it to the inside of the head has to be performed.

[0004]

[Problems to be solved by the invention]

 Therefore, the present invention aims to improve the structure of the head so that the intended purpose can be achieved even if the costly process means of manufacturing and mounting a separate part is abolished. Things.

[0005]

[Means for Solving the Problems]

 In the present invention, an inclined surface protruding inward is formed around the upper surface of the burner head installed at the top end of the mixing tube.

[0006]

[Embodiment of the invention]

 When the gas that has risen from the mixing tube hits the inside of the flat part of the head, it flows in the direction of the surrounding inclined surface, and then discharges to the outside through the mesh and small holes on the inclined peripheral surface of the head. Will be done.

Since the inclined surface portion serves as a barrier to the flow of gas, the one-cushion allows the gas to forcibly bypass the inner peripheral surface.

[0008]

【Example】

 1 is an instrument stopper, 2 is a nozzle, and 3 is a mixing tube.

Reference numeral 4 denotes a plate fitted to the top end of the mixing tube 3, and an umbrella-shaped burner head 6 provided with a net 5 inside is installed above and around the plate.

Reference numeral 7 denotes an inclined surface protruding around the inside of the burner head 6 by press molding. The inclined surface forms a gas bypass flow path. Further, a large number of protrusions may be formed on the inner side surface of the inclined surface portion 7.

[0011]

[Effect of the invention]

 In the present invention, the configuration of the inclined surface around the inside of the head, which is a means to lengthen or change the direction of the gas flow, is performed simultaneously with the press forming of the head, and the preparation of a separate part and the welding process Since these processes are completely unnecessary, it is possible to reduce manufacturing costs and to provide products that are effective for both users and producers.
