DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water heater for use in a bathroom or the like, and more particularly to a wall-mounted hot water heater.

[0002]

2. Description of the Related Art FIGS. 1A and 1B are a side view and a front view, respectively, showing a metal support plate 1 used in a conventional hot water heating apparatus. It is designed to be fixed to the wall by screws struck on the wall. Two claw portions 3 are provided at the upper portion of the support plate 1, and two through holes 5 are opened at a horizontally bent portion 4 at the lower portion of the support plate 1.

When the heating device main body 6 is mounted on the support plate 1 after the support plate 1 is mounted on the wall surface, the claw portions 3 projecting from the upper edge of the support plate 1 as shown in FIG. It is inserted from below into an insertion port 7 (locking portion) provided on the back surface of the heating device main body 6, and at the same time, the projection 9 projecting from the ceiling surface of the concave portion 8 of the heating device main body 6 is bent horizontally by the support plate 1. Through-hole 5 opened in part 4
Was to be inserted from above.

[0004] Further, a hole 10 for duct equipment is provided on the back of the heating device main body 6, and a duct 11 attached to the hole 10 for duct equipment is inserted into a wall opening formed in a wall surface of a bathroom, so that it can be used outdoors. The hot water pipe led from a water heater installed in the heating device is introduced into the heating device main body 6 through the outer periphery of the duct 11 in the wall opening and connected to the internal heat exchanger. The inner peripheral portion of the duct 11 is a ventilation passage 12 for a ventilation fan.

[0005]

In the conventional hot water heating apparatus, the claws 3 provided at the upper two places of the support plate 1 are aligned with the insertion ports 7 of the heating apparatus body 6 as described above. At the same time, the projections 9 provided at the two lower portions of the heating device main body 6 must be inserted in accordance with the through holes 5 of the support plate 1, so that it is troublesome to attach the heating device main body 6 to the support plate 1. It was hanging. In particular,
Considering that a heavy heating device main body 6 having a built-in heat exchanger, a blower, and the like is attached to the support plate 1 at a high position on the wall surface, it is very difficult to vertically align the heating device main body 6 with the support plate 1 at the same time. It was difficult.

Further, in the conventional hot water heating apparatus, since the hot water pipe is guided from the wall opening which is opened at the back surface of the hot water heating apparatus, the installation position of the hot water heating apparatus is limited. The installation location was not flexible.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and has as its object to facilitate installation of a hot water heating apparatus. Further, another object of the present invention is to increase the degree of freedom of the installation position of the hot water heating device.

(It also has a display function of displaying during operation, reception confirmation, etc.), and the light receiving section 53 is exposed from the window 55 of the front cover 45. 56
Is a temperature sensor (thermistor) for detecting the indoor temperature, and 57 is a temperature sensor (thermistor) for detecting the temperature of the heat exchanger 38.

In the above embodiment, the case where the hot water pipe 24 is connected from the right side has been described. In this case, if the hot water pipe 24 is directly introduced into the heating apparatus main body 23, the heating apparatus can be connected from the side of the heating apparatus main body 23. Hot water pipe 24 inside body 23
It is necessary to attach the heating device to the support plate 22 in a state where it is connected, and the installation becomes difficult. However, the installation can be facilitated by providing the piping space 33 between the heating device main body 23 and the support plate 22. it can. Also,
Since the hot water pipe 24 is supported by the pipe support portion 27 of the support plate 22, there is no need to manually support the hot water pipe 24, and this also facilitates construction.

Further, the heating device main body 23 is
When attaching the heating device main body 23, the heating device main body 23 can be easily supported because only the upper insertion port 29 needs to be hooked on the claw portion 26 of the support plate 22. Moreover, after that, the lower part of the heating device main body 23 is
2, the heating device main body 23 can be securely fixed to the support plate 22.

In the above description, the case where the hot water pipe 24 is introduced from the right side is described. However, in the hot water heating apparatus 21, the hot water pipe 24 is also introduced from other directions.
Can be introduced. As shown in FIG. 4A, a thin portion 5 is provided around the left side of the body case 31 as shown in FIG.
For example, when the hot water pipe 24 is protruding from the left side, the knockout section 59 is opened to open the hot water pipe 24 directly into the heating device main body 23. Can be led.

Alternatively, as shown in FIG. 9, the hot water pipe 24 may be introduced from outside into the heating device main body 23 through the passage 60 on the small side of the cross section of the duct 52 and connected to the heat exchanger 38. In addition, on the back surface of the main body case 31, a sub-construction hole 61 smaller than the main construction hole 51 is also opened, and when the ventilation fan 49 is not provided,
A wall opening is made in the wall in accordance with the sub-working hole 61, and the hot water pipe 24 can be introduced from the opening.

FIG. 10 is a view showing a pattern 62 for installing the hot water heating apparatus 21 on a wall surface.
The pattern 62 includes the support plate shown in FIG. 22B and the outer shape 23 of the heating device main body when attached to the support plate 22.
B and FIGS. 51B and 61B of two main and sub construction holes are drawn in full scale. Here, the main construction hole 51B and the sub construction hole 6
Center marks 63 and 64 are drawn at the center of 1B, and perforations 65 and 66 are provided on the outer periphery of the main working hole 51 and the sub-working hole 61. The main marks are formed along the perforations 65 and 66. The position of the working hole 51 or the sub-working hole 61 can be opened.

When the hot water heating apparatus 21 is installed, the pattern 62 is applied to a place where the wall surface is to be installed, and the installation position of the hot water heating apparatus 21 is determined. And the pattern 6
2 through the main hole 51B (or the sub hole 61).
For example, a punch or the like is hit on the center of B) to mark the wall surface. After removing the pattern 62, the jig is used to make the wall open through the wall opening with a jig centered on the mark attached to the wall with a punch or the like. When the opening of the wall is completed, the pattern 62 is again applied to the installation position of the hot water heating device 21B. At this time, the pattern 62 is
5 (66) to open the main hole 51B (or the sub hole 61B). Since the position of the wall opening can be determined by opening the main hole 51B (or the sub hole 61B), the pattern 62 is re-aligned so that the main hole 51B (or the sub hole 61B) and the wall opening coincide. Position. When the position of the pattern 62 is determined in this way, the support plate 22 is placed on the wall surface of the pattern 62 and positioned in accordance with the support plate 22B drawn on the pattern 62. In this state, the support plate 22 is fixed by hitting a screw or the like on the wall surface from the mounting hole 25. Therefore,
The use of the pattern 62 allows the support plate 22
And the heating device main body 23 can be accurately attached, and there is no possibility that the wall opening and the position of the duct 52 will not be aligned later.
