Description

[Detailed description of the invention] This invention relates to a mounting structure that penetrates and fixes the combustor to the roof wall.It is extremely easy to install the combustor from the indoor side, and the body can be adjusted according to the thickness of the roof wall. Even when sliding and fixing in the front and back, the adjustment work is extremely easy and appropriate air supply and exhaust can be ensured.

Conventionally, a structure has been proposed in which a mounting flange is fixed to the body (peripheral wall) of the gas combustor, and the mounting flange is fixed to the inner end surface of the roof wall. Dimensions varied, and there were drawbacks such as if the protruding dimension was too small, which would interfere with hourly exhaust gas, or if the protruding dimension was too large, it would break through the boundaries of the territory.

It is also well known that the exhaust pipe and the supply pipe can be expanded and contracted back and forth using flexible tubes or overlapping piping sections to accommodate the thickness of the roof wall, but in this case, a connecting duct is required, and It requires space for piping work, has a complicated structure, and is expensive.

The present invention was developed in view of the above-mentioned drawbacks, and a mounting flange is slidably inserted into the peripheral wall of the vessel body.
With a simple structure that fixes the mounting flange to the roof wall,
An object of the present invention is to provide a mounting structure for a combustion appliance that can reliably prevent rainwater from entering.

An embodiment of the present invention will be described below based on the drawings.

1 is the main body of the gas combustor, 2 is an inner shell forming a combustion chamber, 3 is an exhaust duct connected to the inner shell 2, and the exhaust duct 3 is connected to a partition plate 4 that divides the tip of the main body 1 into front and rear parts. It is connected. An exhaust port 5 and an air supply port 6 are provided in the distal end portion of the partition plate 4 and the peripheral wall 1b at the central side thereof, respectively. 7 is the gas burner, 8 is the operation button,
9 is a combustion indicator lamp. 10 is a roof wall, and a fastening fitting 11 is embedded and fixed in the roof wall 10.

Reference numeral 12 denotes a mounting flange that is inserted through the main body 1 of the instrument, and a long hole 12c that extends in the axial direction is formed in the peripheral wall 12b of the mounting flange 12, through which a bolt 14 that is screwed into the peripheral wall 1b of the main body 1 is inserted. ing. 13 is a sealing material inserted between the fastening metal fitting 11 and the flange portion 12a of the mounting flange 12, and 15 is a holding flange whose inner diameter is between the holding flange 15 and the tapered portion 12d of the flange portion 12, The sealing material 17 is inserted by inserting a sealing material 17 approximately equal in diameter to hold down the embedded bolt 16 fixed to the fastening fitting 11, passing through the flange 15, flange portion 121a, and sealing material 13, and tightening the nut 18 to the fastening fitting 11. is pushed into the gap having a triangular cross section on the four circumferences and is compressed, and the inner diameter becomes smaller due to the slope of the tapered portion 12d of the mounting flange 12, and the sealing material 17 is crimped onto the outer circumferential surface of the circumferential wall 1b, thereby closing the circumferential wall 1b.
Watertightness is maintained between the mounting flange 12 and the mounting flange 12, and the sealing material 13 is compressed to maintain watertightness between the mounting flange 12 and the roof wall 10, thereby preventing rainwater from entering indoors.

Therefore, the mounting flange 12 is inserted into the long hole 12 on the peripheral wall 1b.
Adjust the position appropriately within the range c, tighten and fix with the bolts 14, and tighten the holding flange 15 and flange portion 12a to the tightening fitting 11 with the embedded bolts 16 fitted and fixed in the tightening fitting 11, and the exhaust port is closed. 5 and the air supply port 6 can be adjusted and fixed at appropriate positions to protrude from the roof wall 10.
The combustion exhaust gas is well discharged from the exhaust port 5, and the combustion air is well taken in from the air supply port 6, and watertightness between the roof wall 10 and the main body 1 is ensured.

In this embodiment, a case is shown in which the mounting flange 12 and the holding flange 15 are simultaneously tightened to the embedded bolt 16 with the nuts 18, but each can be tightened sequentially with separate nuts.
Further, a stud bolt is installed in the mounting flange 12, and the mounting flange 12 is inserted into the stud bolt 16.
It is also possible to tighten the rear presser flange 15 by inserting it into the stud bolt and tightening it.

As explained above, according to the combustor mounting structure according to the present invention, the combustor main body can be attached and fixed to the roof wall with the combustor main body inserted and fixed into the mounting flange in advance, so the combustor main body can be fixed to the roof wall. Since the dimensions on the indoor side can be kept to the necessary minimum, the assembly space can be kept to a minimum, and it is effective in ensuring watertightness, and all assembly work can be done from the indoor side.

When installing the main body, it can be hooked onto the embedded bolt for the first time, so the installation work can be done extremely easily, making the assembly work very easy.
