Description

[Detailed Description of the Invention] "Industrial application field" The present invention uses a forced air supply / exhaust type hot water supply utilizing the space inside the bathtub wall facing the washroom in order to enlarge the bathtub installed in a limited bathroom. Regarding a bath device.

"Prior Art" A conventional balanced bath kettle is a bathroom 40 as shown in FIG.
When the bath pot 41 is installed inside, the bath tub 42 inevitably becomes small because it occupies the space for that portion. In addition, recently, it has been desired to widen the bath tub 42 of a bath installed in a small bathroom such as a housing complex or a condominium for comfortable bathing. However, when there is a space where the bath pot 41 can be installed outside the bathroom 40, there is no problem, but in many cases, since the extra space is not provided outside the bathroom 40, the bathtub 42 is enlarged. I couldn't do it.

Furthermore, recently, a bathtub having a balanced bathtub has been improved so that a space inside the bathtub wall on one side of the bathtub 45 as shown in FIG.
Some 46 have a bath kettle device 47 installed. This is because the space for accommodating the bathtub is widened in the space provided on all four sides of the bathtub, and the bathtub is installed in the space, so the bathtub inevitably becomes small. Moreover,
When performing maintenance and inspection of the bath device 47, the bathtub 45 must be pulled out to the front, and in addition to the original maintenance and inspection work,
Maintenance work was inefficient because extra work such as preparation work and restoration work was required.

"Problems to be solved by the invention" The present invention uses the limited size of the bathroom as widely as possible. The size of the bathtub can be increased by effectively utilizing the space in the wall and accommodating and installing a thin, forced-air supply type bathtub with hot water supply in the space.

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned conventional drawbacks. The bottom squares of a bathtub having a space around the bottom thereof are placed on the respective bases, and the front side of the bases is placed. A space is located on the side of the washing room with a forced-air exhaust type hot-water supply bathtub device equipped with a water heater and an additional heating kettle installed on each stand located on the side And an exhaust passage for connecting the water heater and the reheating kettle to an exhaust port, which is housed and installed in the inside of the bath, horizontally supporting both ends of the mounting table by support rods, and arranged in the upper part of the inside of the housing of the bath device. A space is provided between the wall surface of the fan and a fan that is forcibly taken into the housing from an air supply port for the outside air, and the outside air to be supplied to the gas burner of the bath heater device is forcibly supplied through the gap. A maintenance / inspection window cover is placed in front of the bathtub that houses the bath device. An apron that also serves as a doublet is detachably attached to the front of the bathtub.

[Function] The forced-exhaust type hot-water bath device with a hot water supply can be made thin and can be installed and installed in the space provided inside the bathtub wall, so the balanced-type bath device does not need to have a dedicated space in the bathroom. Therefore, the bathtub can be enlarged. Further, for maintenance and inspection, the bathtub device can be inspected in detail by removing the apron and supporting rod attached to the front of the bathtub without pulling out the bathtub to the front.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

Each of the bathtubs has a space 3 in the tank wall, and the width of the space is approximately 800 to 1000 mm.

In FIGS. 2 and 3, four bases 6 are installed at predetermined positions in the bathroom 1, and two bases 6a on the side facing the washing space 4 are provided.
Forced exhaust type hot-water supply bathtub device 10 in which the mounting bases 7a are fixed to the respective mounting bases 7a, and a thin plate is formed on a shelf plate 8 provided horizontally on the mounting bases 7a.
Is installed. Both ends of this shelf board 8 are supported from the floor of the bathroom 1 by support rods 9, 9 so that a bathtub device placed on the shelf board 8 when hot water does not enter the bathtub 2.
The weight of 10 prevents the bathtub 2 from falling forward.

In FIG. 4, a decorative plate also serving as a maintenance / inspection window lid, that is, an apron 2a, is detachably attached to the front of the bathtub 2, the apron 2a is detached, and the bath rod device 10 is removed by removing the support rod 9. Can be inspected in detail.

Since the forced supply / exhaust bathtub device 10 used in the present invention is formed to have a thickness of about 60 mm, it can be sufficiently accommodated in the space portion 3 provided inside the bathtub 2. I will explain it.

In FIGS. 5 and 6, a housing whose entire outer surface is hermetically sealed
An air chamber 13 is formed on one side inside the housing by being connected to an air supply port 12 provided at one end of 11, and a fan 14 for forcibly taking in outside air is installed in the air chamber 13 The outside air is forcibly sent from an air supply port 15 provided at the upper part of the chamber 13 into a gap 30 provided above the housing 11. further,
The water heater 17 is provided with a first gas burner 18 at the bottom, and a first pipe 19 located above the first gas burner 18 is bent in a zigzag manner to provide a heat exchange section, and one end of the pipe 19 is connected to a water pipe. Tap water is connected and taken in, and hot water is supplied from a currant (not shown) connected to the other end of the pipe.

The reheating boiler 25 has a second gas burner 26 installed in the lower portion thereof, and a second pipe 27 located above the second gas burner 26 is bent in a zigzag shape to form a heat exchange section. One end of the pipe 27 is connected to the bathtub 2, and the other end is also connected to the bathtub 2 via a pump 28.

Next, when the hot water in the bathtub 2 becomes dull, the reheating pot 25
Is heated and the hot water taken from the bathtub 2 by the pump 28 is heated and circulated in the heat exchange section, and the hot water in the bathtub 2 can be boiled by repeating this. The exhaust passages 29 provided at the upper portions of the water heater 17 and the reheating boiler 25 are respectively the fifth and sixth exhaust passages.
As shown in the figure, since it is located inside the housing 11 and a gap 30 is provided between the wall surface of the housing 11 and the exhaust passage 29, the outside air forcibly taken in from the air supply port 12 by the fan 14 is By passing through the gap 30, heat is absorbed by the outside air passing through the exhaust passage 29, and the heat is absorbed by the housing 11.
And, it can be blocked from being transmitted to the bathtub 2 (FIG. 2).

Furthermore, the water heater 17 and the additional heating kettle 25 are heated to heat the pipe 19,
