4 and is supplied into the vaporizing cylinder 1 through the vaporizing cylinder cover 3. On the other hand, the liquid fuel supplied by the fuel supply pipe 2 is also supplied into the vaporization cylinder 1 at the same time. The liquid fuel supplied into the vaporizing cylinder 1 collides with the inner wall of the vaporizing cylinder maintained at a high temperature by the heater 1a integrated with the vaporizing cylinder 1 and is vaporized. 4. Rectifier plate 5
And is ignited by the spark plug on the peripheral surface of the burner head 6 to form a flame and burn.

[0004] In a combustion apparatus having such a configuration, when an assembling operation is performed on a production line, a method is generally employed in which a blower section and a combustor section are successively stacked from the bottom and assembled efficiently. ing. In addition, the blowing efficiency of the combustion air changes considerably depending on the shape of the air guide 14 that connects the blower unit and the combustor unit to form an air path.

[0005]

Since the conventional combustion apparatus has the above-described structure, the assembling operation of the blower unit and the combustor unit from the bottom in the assembling operation requires the air unit 14 to be located above the air guide 14. Screw the vaporizing cylinder cover 3
In the assembly line,
For example, there is a problem that the vaporization cylinder cover 3 may be displaced from the upper surface of the air guide 14 and fall off due to impact or vibration.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and provides a combustion apparatus which realizes an improvement in productivity by preventing a combustor from being displaced or falling off from an air guide during assembly. The purpose is to do.

[0007]

A combustion apparatus according to the present invention comprises a vaporizing cylinder, a vaporizing cylinder cover provided around the vaporizing cylinder, a burner head provided above the vaporizing cylinder, and a stabilizing combustion flame. A blower unit composed of a combustor unit composed of a flame holding ring, a fan for blowing combustion air, a blower motor for driving this fan, these fans, a fan cover surrounding the blower motor, a blower motor cover, etc. And an air guide that is provided between the combustor unit and the blower unit and that forms an air path for guiding combustion air from the blower unit to the combustor unit. Air above the fan cover
Stack the guide and the combustor in order to assemble
In this configuration, a plurality of upright walls are provided integrally with the upper surface of the air guide so that the lower part of the side surface of the carburetor cover of the combustor portion abuts.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. Hereinafter, the combustion device of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a main part showing Embodiment 1 of a combustion apparatus according to the present invention. In FIG. 1, the same reference numerals as those in FIG. 2 have the same configurations as those of the conventional example, and thus the description thereof will be omitted, and only different portions will be described.

Reference numeral 15 denotes a combustor section comprising a vaporizing cylinder 1, a vaporizing cylinder cover 3, a burner head 6, a flame holding ring 7 for stabilizing a combustion flame, a flame detector 8, an ignition plug 9, and the like, and 16 denotes a combustion section. A fan 12 for blowing air for use, a blower motor 10 for driving the fan, a fan unit 13 including a fan cover 13 and a blower motor cover 11 surrounding the fan 12 and the blower motor 10, respectively. The air guide is provided between the blower unit 15 and the blower unit 16 and guides combustion air from the blower unit 16 to the combustor unit 15.

The air guide 17 has a combustor section 15.
A plurality of standing walls 18 with which the lower side of the carburetor cover 3 contacts.
Are integrally provided and, like the vaporizing cylinder 1, are formed as an integral molded product by die casting. Reference numeral 20 denotes a connection port provided in the air guide 17 and the carburetor cover 3.
Is fitted and connected to the combustion air inlet 3a provided at the bottom of the airbag.

In the first embodiment configured as described above, the combustion operation is exactly the same as the operation described in the prior art, and therefore the description is omitted. When assembling the combustion apparatus having this configuration, as described in the related art, the blower unit 1 is used.
In order to assemble the combustor part 15 sequentially from the bottom and start from the bottom, when assembling on the production line, the fan cover 1
The air guide 17 is placed on the upper surface of the air guide 3 , and then the vaporizing cylinder cover 3 is placed on the upper surface of the air guide 17. Since the vaporizing cylinder cover 3 is made of sheet metal and is formed in an unstable shape, for example, impact or vibration is applied between the mounting of the vaporizing cylinder cover 3 on the air guide 17 and the fastening with the screw 19. In the past, there has been a problem that the vaporization cylinder cover 3 may be displaced or come off from the upper surface of the air guide 17. However, according to the configuration shown in the first embodiment, the vaporization cylinder cover 3 Since the plurality of upright walls 18 with which the lower side of the side of the cover 3 abuts are integrally provided, the upright walls 18 are held by the plurality of upright walls 18, so that the vaporization cylinder cover 3 is not screwed down due to shock or vibration on the assembly line. Does not come off from the upper surface of the air guide 17. Thereby, productivity can be significantly improved.

Further, since the air guide 17 is formed as an integrally molded product by die casting, the fan cover 1 is formed.
The air passage can be formed gently from the discharge port 13a of the carburetor 3 to the combustion air inlet 3a of the carburetor cover 3, the air passage pressure loss can be reduced, and the air blowing efficiency can be improved.
