(57) [Summary] [Purpose] To provide a gas burner whose ignition status can be confirmed even under sunlight. [Configuration] Gas cartridge storing liquefied fuel gas
In the portable gas burner of the type directly connected to the upper surface of (1),
A red heat indicator (18) incorporating a platinum filament (17) is arranged on the flame mouth forming surface (16) of the burner unit (4).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a gas burner used in so-called outdoor activities such as mountain climbing, hiking, camping, and more particularly to a gas burner in which a combustion crater member is directly connected to the upper wall of a gas cartridge storing liquefied gas.

[0002]

[Prior art]

 In recent years, outdoor activities have become popular, and the burners used for cooking food and drink at that time are equipped with a combustion crater member in the gas cartridge that stores liquefied gas due to portability and ease of handling. There are many types that are directly connected and used. Conventionally, as a portable gas burner of this type, for example, as disclosed in Japanese Utility Model Publication No. 3-45020, a valve unit detachably connected to the upper end of a gas cartridge containing a liquefied gas, and this valve The structure consisted of a mushroom-shaped burner unit that was pulled out upward from the unit.

[0003]

[Problems to be solved by the device]

 Although this type of gas burner is often used outdoors, the flame color of this type of gas burner when it is completely burned is transparent with a white and blue color. For this reason, it is difficult to see the flame under sunlight in the daytime. Therefore, it is difficult to confirm whether or not the fuel is burning, and it is also difficult to adjust the thermal power (flame). The present invention has been made paying attention to such a point, and an object thereof is to provide a gas burner whose ignition state can be confirmed even under sunlight.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is characterized in that a red heat indicator incorporating a platinum filament is arranged on the flame opening forming surface of the burner unit.

[0005]

[Advantage] In the present invention, since the red filament display device incorporating the platinum filament is arranged on the flame port forming surface of the burner unit, the platinum filament will glow red in the ignited state. You will be able to see it.

【Example】

 1 is an exploded perspective view, FIG. 2 is a front view of a burner, and FIG. 3 is a plan view of the burner. This portable burner includes a valve unit (3) fixed by being screwed into a connection port (2) formed on an upper wall of a gas cartridge (1) storing liquefied fuel gas, and a valve unit (3) of this valve. It is composed of a burner unit (4) led out from the unit (3) and an ignition unit (5) for igniting the burner unit (4).

The burner unit (4) includes an air-fuel mixing pipe (6) extending upward from the upper surface of the valve unit (3) and an umbrella-type burner (7) fixed to the upper end of the air-fuel mixing pipe (6). ), A heat insulating plate (8) arranged so as to cover the lower surface of the burner (7), and an X-shaped Gotoku (9) arranged on the upper surface of the burner (7). ) And the burner (7) are elastically biased in the direction of separation by a compression spring (10) arranged so as to surround the air-fuel mixing pipe (6) therebetween. Also, Gotoku (9) is the upper surface of the burner (7) and heat shield.
It is arranged so as to sandwich the lower surface of (8), and is fixed by the elastic force acting on the burner (7) and the heat insulating plate (8).

The ignition unit (5) includes an L-shaped support plate (11) formed of a thin plate material, a piezoelectric element (12) fixed to one free end of the support plate (11), and a support. The discharge terminal (13) standingly arranged on the other free end of the plate (11), the ground electrode (14) that was set up to support the discharge terminal (13), and the support plate (11) were connected to the burner. It is composed of a fixed block (15) fitted on the lower end of the air-fuel mixing pipe (6) of the unit (4), and the discharge terminal (12) and the ground electrode (15) are connected to the burner (7). ) Is arranged in a state of discharging along the flame mouth forming surface (16).

A red heat indicator (18) incorporating a platinum filament (17) is arranged on the flame forming surface (16) of the burner (7). The red heat indicator (18) is provided on the flame port forming surface (16) corresponding to the direction in which the operation knob (19) of the valve unit (3) is projected.

In the portable gas burner having such a configuration, since the red heat indicator (18) is provided on the flame mouth forming surface (16) of the burner (7), the gas burner is not used when the burner (7) is used. When is burning, the flame at the time of burning heats the platinum filament (17) of the red heat indicator (18), and the platinum filament (17) becomes red heat. For this reason, even if the entire flame is bluish white or colorless and difficult to see under sunlight, the red heat indicator (18) will glow red and red, so the combustion state can be grasped accurately. Not only can raw gas be prevented from being blown out, but the thermal power can be adjusted while checking the degree of red heat.

[0011]

[Effect of device]

 As described above, in the present invention, since the red heat indicator is arranged on the burner forming surface of the burner, it is possible to confirm the gas combustion state in the burner by the red heat state of the red heat indicator. Even if it is difficult to check the flame, it is possible to understand the combustion state and easily adjust the thermal power.
