Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a combustor in which a fuel tank is provided within a main body case.

Conventional configuration and its problems As shown in Figure 1, the fuel tank B built in the main body case A of the hot air heater is generally connected to the left and right flanges on the rear and front sides of the fuel tank B by four screws C. Since the parts were fixed to the support material of the main body case A, many screws were required, and since the left and right flanges on the rear side of the fuel tank B are located deep inside the main body case A, the tightening work was also difficult. It was difficult.

Purpose of the invention Therefore, the present invention reduces the number of screws used to reduce the cost and improve installation workability.

Structure of the Invention In order to achieve this object, in the present invention, a step is provided at the rear corner of the main body case that protrudes inward of the main case, and a long hole is provided in this step so that the flange of the fuel tank can be The front flange portion of the fuel tank is inserted into the elongated hole, and the front flange portion of the fuel tank is fixed to the main body case.

DESCRIPTION OF EMBODIMENTS One embodiment will be described below with reference to the drawings. In FIG. 2, 1 is a box-shaped main body case with an open front. Inside this main body case 1, there is an oil burner (not shown) and a fuel tank 4 storing oil to be supplied to this burner.
It is installed inside. This fuel tank 4 is composed of an upper tank 4a and a lower tank 4b, and a flange portion 4 is attached to both tanks 4a and 4b as a welding margin for these.
c is provided, and this is welded to connect the fuel tank 4.
It consists of On the other hand, the rear plate 2 of the main body case 1 has a step 2a extending vertically on the left and right outer peripheries, and at this step 2a, the fuel tank 4
There is a long hole 2 at right angles to the part that overlaps with the flange part 4c.
b is bored, and the flange portion 4c is inserted and locked into this long hole 2b. Here, since the elongated hole 2b is opened toward the front of the main body case 1, when inserting the flange portion 4c into the elongated hole 2b, the fuel tank 4 is simply moved from the front to the rear.

By doing so, the flange portion 4c of the fuel tank 4 can only move in the front-back direction due to the elongated hole 2b, so when assembling the fuel tank 4, it is only necessary to configure the fuel tank 4 so that it does not move forward. That is, in this embodiment, as in the conventional example, the flange portion 4c at the front corner portion is fixed with screws 6 to the support arm 5 which projects horizontally inward from the left and right side walls 1a, 1b of the main body case 1. There is.

Therefore, as before, the fuel tank 4
Not only does it become unnecessary to fix the four corners with screws, but also the fuel tank 4 can be inserted from the front side of the main body case 1, and the flange part 4c can be inserted into the long hole 2b in the left and right corners of the rear side. If it comes to a dead end, since the elongated hole 2b spans the step 2a, the left and right and front and rear positions can be determined, and the fuel tank 4 can be installed at a predetermined position. Then, the left and right front flange portions 4c
is screwed to the support arm 5 with screws 6.

Therefore, the screws at the left and right flanges 4c at the back of the main body case 1 are no longer required, and the tightening work at the back of the main body case, which is difficult to do in the past, is no longer necessary. This will make your work easier. 3 in the figure is the front plate.

Effects of the invention As can be seen from the above embodiments, according to the invention, the elongated hole that engages the flange of the fuel tank is provided at the left and right steps that protrude inward of the main body case. By simply inserting the flange of the fuel tank into the long hole, the fuel tank can be positioned not only left and right but also rearward.
The work is also easy. In addition, the number of screws used is smaller than in the past, making it cheaper, and there is no need to tighten the screws in the back of the main body case, making the installation process quick and easy.
