In the combustion section 2, when the carburetor 1 is sufficiently heated by the heater 4, the fuel is sent from the fuel pump 7 through the fuel pipe 5 and vaporized. Further, the vaporizing air from the primary air supply pipe 6 and the vaporized fuel are mixed to form a mixture. When this air-fuel mixture is ignited, a flame 8 is formed on the flame nozzle 3 and combustion is accelerated.

[0004]

However, in the above-described conventional structure, since the carburetor 1 and the combustion unit 2 are paired in a combination, the combustion is performed in the hot water supply, heating or cooking combustor requiring a plurality of combustion units. There was a problem that the number of parts 2 increased, and the weight and cost also increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to simplify the structure of a combustion apparatus having a plurality of combustion sections.

Another object of the present invention is to uniformly heat a plurality of vaporizing chambers and maintain stable vaporization.

Further, it is intended to prevent heat loss due to cooling of the vaporizer.

[0008]

In order to achieve the above object, the present invention separates a vaporizer into a plurality of vaporization chambers by a partition wall, and for each vaporization chamber, a mixture gas outlet, a mixing passage, and a combustion section. Is provided.

Further, a heater is built in the partition wall, and the tip of the fuel supply pipe is made to face the partition wall.

Further, a blower pipe on the combustion side not used and 2
The next air blower pipe is configured to be closed by an on-off valve.

[0011]

According to the first aspect of the present invention, even if the carburetor has a single carburetor, the carburetor has a plurality of combustion sections, so that the combustion apparatus is simplified, and the number of assembling steps and the weight are reduced. Further, it becomes possible to provide a low-cost combustion device for a hot water supply / heater, a cooking device, or the like that requires a plurality of combustion units.

Further, in the second configuration, since a single heater can uniformly heat each vaporization chamber, there is no difference in vaporization characteristics between the vaporization chambers, and any vaporizer can be used. The heat of the heater can be rapidly transmitted by using the partition wall as a vaporization surface, and a uniform and sufficient vaporization state can be obtained.

Further, in the third structure, since the through air passing through the vaporizing chamber on the side of the combustion unit which is not used is shut off and the backflow of the secondary air is also prevented, the heat loss due to the cooling of the carburetor is eliminated and the consumption is reduced. Power waste is reduced.
