Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a liquid fuel combustion device such as a portable oil stove.

Structure of conventional example and its problems As shown in Fig. 1, in a conventional liquid fuel combustion device, for example, a portable kerosene stove, a tank holding fitting 3 is fixed to a mounting base 2 with rivets or the like to hold a tank 1. Insert the flange 1a provided on the outer periphery of the tank 1 from the front into the groove 4 provided in the tank holding fitting 3, and tighten the tank fixing fitting 5 to the tank holding fitting 3 with screws or the like so that the tank 1 does not move easily. Tank 1 is fixed. Therefore, according to this configuration, since the flange portion 1a is provided on the outer periphery of the tank 1, the tank becomes larger than the actually required size.
This makes the stove body (not shown) larger than necessary and wastes a lot of material, and when installing a wick up/down device (not shown) on the side of the tank,
Since the flange portion 1a has to be shaped so as to be relieved, there is a problem that the lead up/down device etc. have a complicated shape or become larger than necessary.

There is also another conventional method as shown in FIG. This is the tank holding metal fitting 1 on the bottom of the tank 11.
The upper surface 12a of the tank 2 is fixed by spot welding or the like, and the tank holding fitting 12 is fixed to the mounting table 13 from the back surface with screws or the like. Therefore, according to this configuration, the tank itself is leaner than the one shown in Figure 1, and there is no flange on the side of the tank.
Although it is easy to attach the core up/down device, etc., there are the following problems.

(1) Since the tank 11 and the tank holding fittings 12 are fixed together by spot welding or the like, there is a risk that the bottom of the tank 11 containing fuel will corrode and create holes, so post-treatment such as painting is required, resulting in high costs. arrive.

(2) Since the tank holding fitting 12 is fixed to the bottom of the tank 11 by spot welding, etc., the tank 1
1 must be attached and removed from the back side of the stand 13, which requires a lot of effort during assembly and maintenance.

Purpose of the invention The present invention was created in view of the above problems.It facilitates the installation and removal of the tank, and also reduces tank dimensions (especially in the front-back direction) with a tank shape that does not affect the installation of parts such as the core up-and-down device. The purpose is to reduce the size of the stove body to the minimum necessary.

Structure of the Invention In order to achieve the above object, the present invention provides a fuel tank which has a substantially rectangular shape when viewed from the top and has arcuate or tapered corners, and a fuel tank which is fixed to a stand that holds the tank and which It has an opening for inserting the tank into which one end of the tank including the corner part is inserted, and is set to a size such that the arcuate or tapered shape of the corner part comes into contact with and locks the tank, and the opening is set so as to surround the outer periphery of the tank. It has one substantially U-shaped tank holding metal fitting formed therein, and a cut-and-raised part that is fixed to the stand that holds the tank and holds the bottom of the other end of the tank, and is formed so as to surround the outer periphery of the tank. This is a liquid fuel combustion device consisting of the other approximately U-shaped tank holding fitting and a tank fixing fitting that is fixed to the other tank holding fitting and presses down the tank from above.

DESCRIPTION OF EMBODIMENTS One embodiment will be described below with reference to FIGS. 3, 4, and 5. 21 is a stand, and 22 is a roughly rectangular tank for supplying fuel to the combustion section, with two upper and lower parts.
It consists of parts and is joined by seaming, etc. 2
Reference numeral 3 denotes a substantially U-shaped tank holding fitting A that is fixed to the mounting base 21 with rivets or the like, and has flange portions 23a and 23b bent to surround the tank 22 with an interval approximately the same as the width of the tank 22. is provided, and one end of a substantially rectangular tank 21 having an arc-shaped or tapered corner portion is inserted into the tank, and the tank is set to a size such that the arc-shaped or tapered corner portion abuts and locks. It has an opening 23C for use. Reference numeral 24 denotes a substantially U-shaped tank holding metal fitting B fixed to the mounting base 21 with rivets or the like, and has flange portions 24a and 24b bent to surround the tank 22 with an interval approximately the same as the width of the tank 22. provided,
Furthermore, it has a raised cutout 24c for supporting the vicinity of the seamed portion of the tank 22. 25 is tank 22
is inserted into the opening 23c of the holding fitting A23 and set on the tank holding fitting B24, and then attached to the tank holding fitting B24 with a screw or the like using a tank fixing fitting that holds down the tank 22 from above so that the tank 22 does not easily move.

In addition, in the tank 22 of this embodiment, the part to be inserted into the opening 23c of the tank holding fitting 23 is narrowed down to the same height as the side to be set in the tank holding fitting B24, but this is due to the shape of the tank holding fitting A23. This is to make it as small as possible.

In the above configuration, one side of the tank 22 is inserted into the opening 23c of the tank holding fitting A23, and then the other side of the tank 22 is inserted into the opening 23c of the tank holding fitting B24.
Set the tank fixing fitting 25 by pushing it until it makes contact with the tank holding fitting B from above the tank 22.
By attaching the tank 22 to the tank 24 with screws or the like, the tank 22 can be securely and easily fixed. Therefore, in order to hold the tank 22, an extra flange is provided on the outer circumference of the tank to make the tank 22 larger than necessary, and the extra flange makes it difficult to install a wick up/down device that is attached to the side of the tank. This eliminates the problem of having to make the parts into complicated shapes such as providing relief for the flanges 23a and 23b. In addition, since the tank holding metal fittings are fixed to the tank 22 by spot welding, etc., and the tank holding metal fittings are not attached with screws etc. from the back of the stand, the tank 2
The problems of corrosion of the tank 22 and time-consuming installation of the tank 22 are also eliminated.

Fig. 6 shows another embodiment. In this embodiment, there is no step in the part inserted into the tank holding fitting A23, so press working is easy, and the part inserted into the tank holding fitting A23 also has a core. This has the effect that parts such as the upper and lower devices can be attached.

Incidentally, in each of the above embodiments, the tank holding fittings are taken up as two parts, but the same effect can be obtained even if they are integrated.

Effects of the Invention As described above, according to the present invention, since the tank can be made smaller, the entire apparatus can be made more compact.

Furthermore, since the tank retaining metal fittings are not welded to the tank, the problem of tank corrosion as in the conventional example can be solved.

Furthermore, since the tank holder can be attached and removed from above the holder, it is much easier to attach and remove the tank holder than in the conventional case.
