Description

[Detailed description of the invention] (Industrial application field) This invention relates to a structure for mounting a horizontal water heater in a wall hole installed in a high-rise apartment complex.

(Prior art) In places with narrow indoor spaces, such as high-rise apartment buildings, there is a demand for water heaters to be installed horizontally in wall holes. It is required to be simple and easy to install. Therefore, as a conventional mounting structure of this type, there is only one with a single seal structure, for example, as seen in the mounting structure of a water supply/exhaust pipe of a water heater.

(Problem to be solved by the invention) With the above conventional technology, it is impossible to guarantee perfect sealing performance, so rainwater does not infiltrate indoors during rain, especially when rain is accompanied by strong winds. Moreover, the structure is complicated, and the installation work is often difficult. Therefore, this invention provides a water heater mounting structure that solves the above problems by having a double seal structure that is simple and easy to install.

(Means for solving the problem) In order to solve the above problem, this invention integrates functional parts such as a combustion chamber and a heat exchanger into an outer shell B installed horizontally in the mounting hole 1 of the wall A. In a water heater in which the internal structure C that can be changed is inserted while maintaining a certain relative position,
A mounting flange 2 provided on the outer periphery of the outer shell B is fixed to a metal frame 3 fixed to the wall A with a sealing material 4 interposed therebetween, and a sealing material is provided at the attachment part between the mounting flange 2 and the outer shell B. 5 was pressed against a presser plate 6.

(Function) Therefore, the sealing material 4 interposed between the wall A and the mounting flange 2, the mounting flange 2 and the outer shell B
The indoor and outdoor areas are completely isolated by the double seal of the sealing material 5 which is pressed against the mounting part of the outer shell B by the presser plate 6, and the mounting flange 2 which is pre-installed on the outer shell B.
It can be installed and fixed simply by fastening it to the wall A side.

(Embodiment) An embodiment of the water heater mounting structure according to this invention will be described below with reference to the drawings.

In the drawing, A is a wall such as a high-rise apartment building, 1
B is an outer body with an opening 7 at the base end, an air supply port 8 on the lower surface of the distal end, and an exhaust port 9 on both corners of the distal end. in,
It is inserted laterally into the mounting hole 1 and horizontally installed at a predetermined position by means of mounting and fixing means, which will be described later.
C is the internal structure of the water heater, in which functional parts such as a combustion chamber 10, a heat exchanger 11, a burner 12, an air supply fan 13, a flasher 14, and an electrical box 15 are connected to piping connections 16, support legs 17, etc. The internal structure C is connected to the outer shell A.
The air supply port 8 and exhaust port 9 of the outer body B can be connected by simply sliding the support leg 17 into the umbilical cord through the proximal opening 7 of the outer body B.
The partition plate 19 fixed between the sealing material 21 and the partition plate 20 fixed to the heat exchanger 11 of the internal structure C
are pressed against each other to airtightly partition the air supply side and exhaust side in the outer shell B, and the engagement pieces 22 fixed to both sides of the inner surface of the proximal end of the outer shell B are attached to the base plate 18 of the internal structure C. The provided stopper pieces 23 hit, and by fixing these with set screws 24, the internal structure C is firmly held so that it does not escape from the outer shell B.
On the other hand, the internal structure C can be installed inside the water heater while maintaining a certain relative position without impairing the various functions of the water heater. Reference numeral 2 denotes a mounting flange provided on the outer shell B so that its mounting position can be changed.It is provided in an annular shape around the entire outer periphery of the outer shell B, and as a means for changing the mounting position, a fixed interval l is provided on the outer shell B. A reinforcing plate 27 with screw holes 26 that match the screw insertion holes 25 drilled in rows is fitted and fixed in the outer shell B, and set screws 28 of the mounting flange 2 to the outer shell B are set according to the thickness of the wall A. Although an example in which the mounting position can be freely selected is shown, any other conversion means may be used. Also, 3
2 is a metal frame such as an angle member fixed to the indoor side of the wall A, and a mounting bolt 29 for mounting and fixing the mounting flange 2 is fixed to the metal frame 3. 4
is a sealing material interposed between the mounting flange 2 and the metal frame 3, and the mounting flange 2 is tightened with a nut 30 via the sealing material 4 to the mounting bolt 29 attached to the wall A via the metal frame 3. As a result, the sealing material 4 provides an airtight seal between the wall A and the mounting flange 2. Reference numeral 5 denotes a seal material provided at the attachment portion between the outer shell B and the mounting flange 2, and the seal material 5 is attached to the bolt 3 on the mounting flange 2.
1 and a retainer plate 6 fixed by nuts 32, the retaining plate 6 is pressed against the joint surface side thereof to maintain the airtightness of the attachment portion between the outer shell B and the attachment flange 2. The presser plate 6 is annularly provided around the entire outer periphery of the outer body B. In addition, 33 is a notch recess provided at the bottom of the base end opening 7 of the outer body B, and a rising piece 34 provided in the notch recess 33 and an engaging stepped portion provided in the base plate 18 of the internal structure C. 35 is pressed against the packing 36 when the internal structure C is inserted into the outer shell B. 37 is a lid of the proximal opening 7 of the outer body B;
8 is a front cover, 39 is a water supply pipe, 40 is a gas pipe, and 41 is a hot water supply pipe.

(Effect of the invention) In the above structure, the outer shell B that is passed through the mounting hole 1 of the wall A is fixed with a set screw 2 at a predetermined position of the outer shell B.
The mounting flange 2 fixed by 8 is attached to the mounting bolt 29 which is attached to the wall A via the metal frame 3.
Since it is installed horizontally by interposing the sealing material 4 between them and tightening it with a nut 30, the sealing material 4 is pressed against the attachment part of the outer shell A and the mounting flange 2 by the holding plate 6. The indoor and outdoor areas are separated by the double seal of the sealing material 5, and since the sealing material 5 can be screwed to the flange 2 using the holding plate 6 in advance, it can be fixed to the outer shell B. Attach the mounting flange 2 to the wall A side with bolts 29
It can be easily and reliably installed by simply attaching it to the However, when installing a horizontal water heater into a wall hole,
Since it has a structure that can be easily installed based on a double seal, its sealing performance is improved and the indoor and outdoor areas are completely separated, so there is no rainwater entering the room during rain accompanied by strong winds, and the installation process is easy. This method is easy and reliable, and has a simple structure, so it has high practical value especially when applied to horizontal water heaters that are installed using holes in the walls, such as in high-rise apartment buildings.
