Description

[Detailed Description of the Invention] The present invention relates to a gas bath kettle, and particularly to a so-called wall-embedded type bath kettle with a water heater, in which a part of the vessel body is buried in a wall surface.

A conventional wall-embedded bathtub has a structure shown in FIG. 1, with an opening 2 provided in the wall adjacent to the bathtub 1, a container 3 housed in the opening, and a heat exchanger 4 protruding from the opening 2. A pair of water pipes 5, 5 are connected to a pair of through holes 6, 6 provided in the side wall of the bathtub 1, respectively, in an airtight manner around the outer periphery, so that only a part of the vessel body 3, the kettle device 7, and the exhaust pipe 8 are exposed to the outside. It stands out. In this case, the vessel body 3 is extremely small compared to that of a bath pot with a water heater, and even if the gap between the vessel body 3 and the adjacent wall surface 9 is small, it can be installed as long as the vessel body 3 has the width W.

However, if the bathtub with a water heater is of the wall-embedded type, the dimensions of the vessel are large, so if the distance between the bathtub and the adjacent wall 9 is small,
It cannot be installed in an existing house.

The present invention solves this drawback of the conventional method by dividing the body into parts and installing it, thereby making it possible to install a large bathtub with a water heater even when there is little distance from the adjacent wall. be.

The technical means of the present invention taken to achieve the above object is that the vessel body 3 is a box-shaped first chamber 22 equipped with a hot water supply heat exchanger 21 and a box-shaped first chamber 22 equipped with a bath heat exchanger 11. The second chamber 12 is removably connected to the lower side of the first chamber 22, and the second chamber 12 is connected to the first chamber 22 below the bath heat exchanger 11 in the second chamber 12. A main burner housing chamber for the bath which is opened is formed, and the upper end opening of the exhaust flue 13 of the bath heat exchanger 11 and the exhaust gas collection part 31 of the hot water heat exchanger 21 are formed.
The lower end opening of the communication path is fitted in the horizontal direction so as to be freely inserted and removed, and the main bath burner 14 is supported by the bottom of the first chamber 22 so as to protrude toward the second chamber 12. The support position of the is set so that it is located below the bath heat exchanger 11 when the first and second chambers are combined, and a pair of supports are provided on the end face of the second chamber 12 that communicate with the bath heat exchanger 11. This is because the water pipes were made to protrude.

The above technical means of the present invention operates as follows.

Since the container body 3 can be separated into the first chamber 22 and the second chamber 12, the second chamber 12 is buried in the wall surface in this separated state.

Next, when the first chamber 22 is attached to the second chamber 12, the main bath burner 14 supported on the first side is removed.
is located below the bath heat exchanger 11, and the upper end opening of the exhaust flue 13 and the lower end opening of the communication path to the exhaust gas collecting section 31 on the first chamber 22 side are fitted in the horizontal direction. Since the first chamber 22
By installing the exhaust flue 13 to the exhaust collecting part 3
The circuit to 1 is connected.

Since the present invention has the above configuration, it has the following unique effects.

The second chamber is housed and fixed in the opening in the wall in advance and the water pipe is connected to the bathtub, and then the first chamber is attached to the second chamber, so there is no space between the fixture mounting wall and the opposite wall. It can also be installed in locations that are smaller than the overall width of the . In other words, a large bathtub with a water heater can be installed even in a narrow space.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Fig. 2 shows the installed state of the bathtub with water heater according to the embodiment of the present invention.
1 has the same structure as the conventional wall-embedded type,
It is housed in the vessel body 3 together with the hot water supply heat exchanger 21,
The bath heat exchanger 11 is located below the hot water supply heat exchanger 21. Furthermore, the inside of the container body 3 is divided into two chambers, one of which is a first chamber 22 in which a hot water supply heat exchanger 21 is housed, and a second chamber 12 in which a bath heat exchanger 11 is housed. Ru. An exhaust flue 13 is connected to the lower bath heat exchanger 11, and the upper part of the exhaust flue is biased toward the first chamber 22, and its upper end is covered with the other hot water heat exchanger 21. An exhaust pipe 32 protrudes from the upper surface of the vessel body 3 and communicates with the exhaust gas collecting portion 31 located at the top of the container.

Reference numeral 14 denotes a main burner for the bath, which is provided below the heat exchanger 11 for the bath, and a valve device ( (not shown), and these main burners are ignited and extinguished as necessary by the valve device.

The vessel body 3 has an approximately L-shaped external shape, and the majority of the second chamber 12, that is, the bath heat exchanger housing portion forms a protruding portion 15, and the external shape of the protruding portion is set to be smaller than the external shape of the wall-embedded bath pot. Moreover, the pair of water pipes 5, 5 of the bath heat exchanger 11 is connected from the tip surface 16 of the protrusion 15.
stands out. The pitch of the water pipes 5, 5 is set appropriately, and a female screw part is provided on the inner periphery of the tip opening, and the through holes 6, 6 provided in the bathtub 1 are provided with a female screw part.
The end flanges 42, 42 of the water pipes 5, 5 are brought into contact with each other through the gasket 41, and the threaded cylinders 43, 43 with flanges are screwed together from the inside of the welding tank 1 to connect the water pipes 5, 5 to the transparent part of the bathtub 1. The outer periphery is connected to the holes 6, 6 in an airtight manner.

Further, the bathtub with a water heater having the above structure can be further separated into the first chamber 22 and the second chamber 11, and the tip of the exhaust flue 13 of the second chamber 11 is connected to the exhaust gas collection part 31 of the first chamber 22. When the side portions of the first chamber 22 and the second chamber 11 are brought into contact with each other and the bent tongues 51 and 52 at the periphery of the contact portions are screwed together, the structure is integrated as shown in FIG. 2. At this time, the first room 22
The bath main burner 14 fixed to the side is inserted below the bath heat exchanger 11 through an opening 17 opened at the lower part of the side wall of the second chamber 12. (Figure 3).

In the bathtub with a water heater having the above structure, the first chamber 22 and the second chamber 12 are separated, and the second chamber 12 is first accommodated in the opening 2 provided corresponding to the bathtub 1, and the water pipe 5 is , 5 are directly connected and fixed to the melting tank 1,
Next, when the first chamber 22 is joined in the above-described procedure, it is installed in the state shown in FIG. 3.

Therefore, the distance from the adjacent wall surface 9 is the distance W ₂ from one side of the first chamber 22 to the tip of the main bath burner 14.
However, it is possible to install a bathtub with a water heater.

In addition, the main bath burner 14 fixed to the first chamber 22 side is made removable from the first chamber, and the first chamber 22
If the structure is such that it can be installed after connecting it to the second chamber 12, the minimum distance between it and the adjacent wall surface to which it can be attached will be further reduced.
