Description

[Detailed Description of the Invention] The present invention relates to a liquid fuel combustion device, and in particular to a fuel tank portion thereof, and its purpose is to ensure safe combustion even in a single fuel tank taken out from a main body case.

As shown in FIG. 1, a conventional liquid fuel combustion device has a combustion air intake 4' and a frame 5' provided at the lowest part of a lower tank 3' that constitutes a fuel tank 2' built into a main body case 1'.
A space A' is secured by the support height of a fuel tank support fitting 6 provided on the pedestal 5 by fastening or the like.

However, in this configuration, during service, for example, when cleaning the inside of the fuel tank 2', if the fuel tank 2' is not assembled into the support fitting 6' as shown in Fig. 2, and the combustion is performed outside the main body case 1', the combustion will occur. The air intake port 4' is in contact with the floor ff1K' and cannot take in combustion air.

Therefore, if combustion continues after ignition at this time, a strong odor and medium will be generated without reaching the red heat of the red-hot net T', and an abnormal flame will be generated due to the increase in raw gas due to heating, or the wick guide cylinder 8
This could lead to an extremely dangerous situation such as backfire to the gas filling the inside.

Therefore, the present invention attempts to eliminate the above-mentioned drawbacks of the conventional fuel tank by providing legs to the fuel tank.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

In Figure 3, 1 is the main body case;
A fuel tank 2 is provided inside.

In the past, a wick guide tube 3 and a glowing net 4 were provided above the fuel tank 2.

In addition, 5 is a reflective plate, 6 is a protective guard, 7 is a cartridge tank storage part, 8 is the leg which supports the fuel tank detachably, and 9 is the metal fitting which fixed the fuel tank 2 to the leg 8.

In the above configuration, in a normal state, air is taken in from the combustion air intake port 10 and combustion is performed in the upper part of the wick guide tube 3 and the red-hot net 4 section.

Further, when cleaning the inside of the fuel tank 2, for example, the metal fitting 9 is removed and the fuel tank 2 is removed together with the core guide tube 3 from inside the main body case 1 as shown in FIG. 4, and the cleaning is performed.

After this cleaning, a combustion test is performed before installing the main tank 2 into the main body case 1, and in this embodiment, this combustion test can be performed very easily.

In this embodiment, the leg 1 made of wire rod as shown in FIG.
1 is integrally provided in the lower tank 2a by a diaphragm.
It was removably fitted into the opening a' of the.

As a result, as shown in Figure 4, the combustion air intake port 1
A space A is provided between 0 and the floor surface, and air is sufficiently supplied from this space A to the 3 parts of the core guide cylinder.

For this reason, in this combustion test, there were no strong odors or large amounts of medium generated, or abnormal flames or flashbacks, as in the past.

In addition, in this embodiment, the cylindrical portion 2a' is provided by drawing, and the opening a' of the cylindrical portion 2a' is provided above the constant oil level to prevent oil leakage from the forming portion of the cylindrical portion 2a'. There is.

That is, by fixing conventionally known leg fittings to the lower tank 2a of this embodiment by spot welding or the like, it is possible to maintain the space A when the fuel tank 1 is taken out, but it is possible to maintain the space A when the fuel tank 1 is taken out. This would lead to problems with oil leakage or require post-treatment (painting, etc.), resulting in a costly design.

It is also conceivable to secure the space A by providing a plurality of protrusions in the downward direction at the lowest end of the lower tank 2a.
Since the material is in a tight drawing state with a, etc., the material hardens, which leads to the occurrence of cracks, etc.

In contrast, in this embodiment, the space A is secured by attaching legs 11 that are separate from the lower tank 2a.
No oil leakage or cracking of the lower tank 2a occurs, and since no welding is required, no post-processing is required and it can be provided at low cost.

6 and 7 show another embodiment of the present invention, in which the fuel tank 2 is supported by rectangular legs 11' instead of the legs 11, and there is a space between the legs and the floor surface. I secured an A.

As described above, according to the present invention, stable combustion can be carried out when conducting a combustion test with the fuel tank removed from the main body case, so unlike conventional methods, it is possible to generate a large amount of strong odor or medium, or to avoid abnormal startup. It will not cause flames or backfire.
