Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas stove with reduced temperature rise of burner components.

[0002]

2. Description of the Related Art A conventional gas stove has a burner body made of, for example, cast iron or brass, a stainless steel plate, a saucepan made of stainless steel or an enamel steel plate, and Gotoku is made of cast iron, an enamel steel plate, or a chrome-plated steel material. Many materials do not have good thermal conductivity. Further, these members are generally arranged separately from each other, and the members are often discolored or seized due to spillage because they are likely to be heated during use.

[0003]

The present invention pays attention to such a point, and obtains a gas stove in which the temperature rise of the constituent members is relatively small and there is no discoloration or seizure, and it is easy to maintain a good appearance. This was done as an issue.

[0004]

In order to achieve the above-mentioned object, in the present invention, a flat or substantially flat plate-like upper surface shape is provided, and a lower surface is provided with an air-fuel mixture chamber communicating with a mixing pipe,
In addition, a burner plate provided with a communication hole for supplying the air-fuel mixture in the air-fuel mixture chamber to the flame hole is provided, and this burner plate is supported by the top plate in close contact with the top plate of the stove, and the burner plate and the top plate are It is made of a material having good thermal conductivity. Further, the Gotoku part made of a material having a good thermal conductivity is provided on the upper surface of the burner plate either integrally or in close contact. As the material having good thermal conductivity, one having a thermal conductivity of 200 W / mK or more is suitable, and copper, aluminum, or an alloy thereof can be used. In particular, aluminum or aluminum alloy is most suitable because it can maintain a silver-white appearance.

[0005]

[Function] The burner plate and the top plate have good thermal conductivity, and the burner plate has a flat plate shape and a large area, so that the constituent members are in close contact and thermally integrated. As a result, heat is dissipated from the burner plate surface, and heat conduction and heat dissipation to the top plate are actively performed. For this reason, the temperature rise of the burner plate becomes small, and discoloration or seizure of boiling water does not occur. Further, when the Gotokube made of a material having good thermal conductivity is provided in close contact with the burner plate, the temperature of the Gotokube is less likely to rise, and seizure or discoloration of the soup or the like does not occur on the Gotokube. Aluminum and its alloys have been rarely used in burners until now because they may be locally overheated and melted in the case of flashback, but this invention reduces the temperature rise of the burner plate and melts it. Since it is prevented, the burner can be used easily. In this case, the thermal conductivity is good, discoloration is unlikely to occur, and the appearance is excellent, which is effective in improving the commercial value of the gas stove.

It is performed by placing the top plate 17 on the burner mounting hole edge 17a. The lower surface of the outer peripheral edge 1a has a shape conforming to the upper surface of the top plate 17,
It is arranged to be in close contact with the top plate 17 only by placing it.

Reference numeral 21 denotes an auxiliary burner having a well-known structure composed of a burner base 22 and a burner cap 23. The auxiliary burner 21 is mainly provided by supporting the burner base 22 on a mixing tube 25 fixed to the hob body via a mounting plate 24. The spark plug 26, which is arranged at the center of the burner 11 and is shown by a chain line, and a thermocouple (not shown) are appropriately arranged around the auxiliary burner 21. Reference numeral 27 is a soup saucer attached to the middle portion of each mixing tube. The burner plate 1 is chamfered on the outer periphery so that the broth flows easily, and the burner mounting hole 18 has a high edge to prevent the broth from entering the interior.
