Description

[Detailed description of the invention] [Industrial field of application and overview of the invention] This invention relates to an outdoor bath pot.
The bath pot can be installed without creating a large gap between this type of bath pot, which is installed near a wall surface, and the wall surface, thereby reducing the installation space for the appliance. be.

[Prior Art and Problems Therein] There is a bathtub for outdoor installation that is made thin so that the installation space can be reduced. An example of this type of bathtub is shown in FIG. 5.

The body case 19 of the bathtub 1 is provided with pipes 17 and 18 that protrude from the back side of the appliance and communicate with a heat exchanger (not shown).
The tips of 7 and 18 are the bathtub pipes D to the bathtub A side.
These are piping connection parts 11 and 12 for connecting D. The bathtub pipes D and D protruding from the wall C to the outside and the respective connecting portions 11 and 12 are connected to each other via connecting rubber pipes E and E.

In this device, when the gas burner (not shown) is ignited to put the appliance into use, the water in the water circuit is heated and heated in the heat exchanger section, and the water in the bathtub A is heated by the heat exchanger section. The water is circulated between them and the bath is heated.

However, with the above-mentioned conventional bathtub, there was a problem in that even if the bathtub was made thinner, the space for installing the appliances was not reduced very much.

In the above-mentioned conventional type, this is because the bathtub 1 and the wall C
This is because the equipment cannot be installed unless a large gap is secured between the two.

That is, in the case of the above-mentioned conventional one, each connection part 11, 12 for connecting the bathtub pipes D, D to the bathtub A.
protrudes from the main body case 19 of the bathtub 1 toward the rear, so that each of these connecting parts 11,
In order to connect the bathtub pipes D and D to the bathtub pipes D and D, a gap for piping work must be created between the bathtub pot 1 and the wall C. Therefore, even if the bathtub 1 is made thinner in order to reduce the installation space of the bathtub 1, when the bathtub is actually installed, the work space secured at the back of the bathtub 1 will be limited. This will protrude extra from the wall C, and the space for installing the appliance will increase accordingly.

On the other hand, there is a forced circulation type bath pot that can reduce the distance between the bath pot 1 installed outdoors and the bathtub wall. The connection fittings on the pot 1 side are simply connected using normal piping, and this piping does not need to have a large diameter as is required when using conventional natural circulation bath pots. It is highly flexible and can reduce the distance between the bathtub 1 installed outdoors and the bathroom wall.

However, this type of bathtub is difficult to apply to bathtubs that are compatible with already installed natural circulation bathtubs. When applied to this type of bathtub, problems similar to those of the conventional bathtub described above arise.

[Problem] The present invention has been made in view of the above points, and is ``a bathtub pipe that is set to correspond to a natural circulation type bathtub and that protrudes vertically from the bathroom wall C at a constant interval. A bathtub A equipped with D and D;
Connecting parts 12, 1 at both ends of the circulation heating circuit of the bath pot 1
The problem is to make it possible to connect a circulation circuit to the bathtub pipes D and D of the existing bathtub A while the bathtub 1 is attached to the wall. .

[Means] The technical means of the present invention taken to solve the above-mentioned problems are as follows: ``The bathtub 1 has a built-in forced circulation heating circuit equipped with a circulation pump P and a heat exchanger, and the main body case 19 is The rear surface of this main body case 19 is attached to a wall C as a flat rectangular parallelepiped in the front and back, and a rectangular parallelepiped-shaped piping box 3 having substantially the same cross section as the main body case 19 is connected below the main body case 19 to attach the front surface of the main case 19 to the wall C. The lid body 35 of the piping box 3 is made removable, and the rear plate of the piping box 3 is provided with an opening through which the bathtub pipes D, D protruding from the wall C are penetrated. Connecting portions 1 that become the inlet and outlet sides of the forced circulation heating circuit in the bathtub 1 from symmetrical positions on the bottom of the main body case 19
2 and 11 protrude, and the connection part 11, which is the inlet side of the forced circulation heating circuit, is made to protrude lower than the other connection part 12, which is the outlet side, so that the height difference between the two can be adjusted to the spacing between the bathtub pipes D, D. The connecting portions 12 and 11 and the bathtub pipes D and D are respectively connected by flexible connecting rubber tubes E and E, respectively.

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

Bathtub pipes D and D protrude from the bathroom wall C at regular intervals vertically to correspond to a natural circulation type bathtub.

Therefore, with the lid 35 of the piping box 3 removed, the bathtub pipes D and D are passed through the openings formed in the rear plate of the piping box 3, and the main case 19 is attached to the wall C. Thereby, the bathtub pipes D and D are housed in the piping box 3. Connection parts 12, 11
project into the arrangement box 3 from symmetrical positions on the bottom surface of the main body case 19 above the front and upper sides of the opening, and
The connection part 11, which is the inlet side of the forced circulation heating circuit, is made to protrude lower than the other connection part 12, which is the outlet side, and the difference in height between the two is made to approximately match the interval between the bathtub pipes D, D, so that the downward A connecting portion 11 is located in one side region near the tip of the upper bathtub pipe D, and a connecting portion 12 is located in the other side region near the tip of the upper bathtub pipe D. The distance between the connecting portion 11 and the corresponding bathtub pipe D matches the distance between the connecting portion 12 and the corresponding bathtub pipe D.

Then, when these two are connected separately, bathtub A
The inside and the inside of the bath pot 1 are connected to each other so as to be able to circulate.

After that, when the lid 35 of the piping box 3 is reinstalled,
The piping connections between the connecting parts 12, 11 and the bathtub pipes D, D are housed in the piping box 3 and cannot be seen from the outside.

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

A forced circulation heating circuit can be connected to an existing natural circulation type bathtub A with the bathtub 1 attached to the wall C. Therefore, the bathtub can be installed even in a narrow space.

Furthermore, since the connection work can be carried out inside the piping box 3 with its front open, it is easy to perform the pipe connection work, and furthermore, after the work is finished, the connection part is no longer visible, so the appearance is not unsightly. It can be resolved.

Furthermore, the connection part 1 corresponding to the bathtub pipes D, D
