Abstract

(57) [Summary] [Purpose] To simplify the piping around the bathtub body. Increase the amount of air mixed in the bath water. [Structure] An intermediate portion of the circulation pipe is brought close to the rim lower surface of the bathtub body, and an air suction portion is provided at a portion near the rim of the pipe. [Effect] Since the hot water and the mixed air can be fed by the discharge water pipe, the air pipe is not required and the pipe can be simplified. Since the air intake portion can be arranged at a high position, it is possible to avoid obstruction of air intake by the bath water head in the bath body and increase the amount of mixed air.

[Problems to be solved by the device]

 However, since the air suction part a is provided integrally with the jet outlet b, a total of two pipes are required at the jet outlet b, a water pipe e and an air suction pipe f. The area where the piping hole for attaching the kettle can be drilled becomes narrow, which makes it difficult to install the reheating bath kettle. Also, since the ejection port b is installed below the water surface, the air suction part a is It has a drawback that it becomes lower than the water level, and the intake of air is obstructed by the head of the bath water, which reduces the amount of intake air.

[0004]

[Means for Solving the Problems]

 In the present invention, the base end of the circulation pipe is connected to the suction port of the bathtub body, the tip is connected to the ejection port of the bathtub body, and the circulation pump is connected in the middle of the circulation pipe, and the circulation of the hot water from the circulation pump In a bubble-generating bathtub that ejects hot water mixed with bubbles toward the inside of the bathtub from the jet outlet, place the middle part of the circulation pipe close to the bottom surface of the rim that is formed in a protruding shape on the upper edge of the bathtub body. , An air intake part is provided near the rim of the circulation pipe, a nozzle is installed in the circulation pipe connected to the circulation pump and upstream of the air intake part, and the air intake part is located higher than the jet port. It is intended to provide a bubble generating bathtub characterized by the above.

【Example】

 Embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a bubble-generating bath A including an air suction portion according to the present invention. The bath A has two jets on each of the front and rear side walls of a bath body 1 having a substantially box-like top opening. The outlet 2 and the suction port 5 are provided, and the base end of the circulation pipe R is connected to the suction port 5 and the tip of the circulation pipe R is connected to each two jet ports 2.

The circulation pipe R includes a suction water pipe 51 on the base end side and a discharge water pipe 3 on the tip end side, and a circulation pump P is connected to the middle of the circulation pipe R. That is, the suction water pipe 51 is connected to the suction side of the circulation pump P, and the discharge water pipe 3 is connected to the discharge side of the circulation pump P.

The discharge water pipe 3 is close to the lower surface of the rim 11 formed in a protruding shape on the outer side of the upper end edge of the opening of the bath body 1, and the discharge water pipe body 31 and the discharge water pipe body 31 which are arranged along the outer side surface of the bath body 1. It is composed of a connection water pipe 32 that communicates the water pipe body 31 with each of the jet outlets 2, and a pump side water pipe 33 that communicates the central portion of the discharge water pipe body 31 with the discharge side of the circulation pump P.

Further, air intake portions 4 are formed on both sides of the connection portion between the discharge water pipe main body 31 and the pump side water pipe 33.

As shown in FIG. 2, the air suction section 4 has an air suction pipe 41 standing on the upper surface of the discharge water pipe body 31 and communicated with an air suction port 42 provided on the upper surface of the rim 11. 43 is a cap that covers the air inlet 42.

Further, a nozzle 44 is provided inside the discharge water pipe main body 31 upstream of the connection portion of the air suction pipe 41 so that bath water from the circulation pump P is jetted from the nozzle 44 into the air suction portion 4. I am trying to do it.

The embodiment of the present invention is configured as described above, and when the circulation pump P is operated, the bath water in the bath body 1 is sucked into the circulation pump P via the suction water pipe 51, and the pump It is pressurized by the nozzle P and ejected from the nozzle 44 into the air suction portion 4. Due to the flow of the bath water, a negative pressure is generated inside the air suction unit 4, and the negative pressure causes outside air to be sucked into the air suction unit 4 through the air suction pipe 41 so that air is mixed into the bath water. ing.

The bath water mixed with air in this way passes through the discharge water pipe body 31 and the connection water pipe 32 and is ejected from the ejection port 2 into the bath body 1 as a bath water containing air bubbles.

As described above, since both the hot water and the mixed air are supplied to the jet port through the discharge water pipe 3, no separate air suction pipe is required, and the piping around the bath body 1 is simplified. As a result, the range of the position of the hole for piping in the bath heater for reheating, which is formed in the side wall of the bathtub body 1, becomes wider, and the piping work becomes easier.

Further, since the air suction part 4 is provided in the discharge water pipe main body 31 adjacent to the lower surface of the rim 11 of the bathtub main body 1, the air intake part 4 is located higher than the water level in the bathtub main body 1, and the bath Since it is possible to avoid obstruction of air intake by the head of the hot water, a large amount of air can be mixed into the bath water.

[Effect of the device]

 Equipped with a jet outlet on the side wall of the bathtub and a circulation pump connected to the jet outlet via a discharge water pipe, air is drawn into the bath by the flow of the bath water from the circulation pump, In a bubble-generating bath configured to eject hot water mixed with bubbles from the outlet toward the inside of the bath, place the middle part of the discharge water pipe between the circulation pump and the outlet close to the bottom of the rim of the bath body, and By providing the air intake part, the air intake part will be at a high position, and it is possible to avoid obstacles to the air intake by the head of the bath water in the bath body, so mix a large amount of air into the bath water. In addition, since no air piping is required, the piping around the bathtub body is simplified, so the weight of the piping can be reduced and labor required for loading can be saved. In addition, the range of the position of the hole for piping in the reheating bath pot drilled on the side wall of the bathtub body is widened, and the piping work is also facilitated.

Furthermore, since the air suction portion is provided in the circulation pipe to allow the bath water containing bubbles to be ejected, the ejection port can be made compact.
