However, since the air suction portion a is provided integrally with the jet port b, a total of two pipes are required at the jet port b: a water pipe e and an air suction pipe f. However, for this reason, the range in which the pipe hole for mounting the additional heating bath can be drilled becomes narrower, and the installation of the additional heating bath becomes difficult.
Further, since the jet port b is installed below the water surface, the air suction portion a becomes lower than the water level in the bathtub, and the suction of air is hindered by the head of the bath water, so that there is a drawback that the amount of suction air is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a bubble generating bathtub A having an air suction section according to the present invention. The bathtub A is provided with two jets on each of the front and rear side walls of a substantially box-shaped bathtub body 1 having an open top. An outlet 2 and a suction port 5 are provided, and the base end of the circulation pipe R is connected to the suction port 5.
In addition, the tip of the circulation pipe R is connected to each of the two ejection ports 2.

The circulation pipe R comprises a suction water pipe 51 on the base end side and a discharge water pipe 3 on the front end side. A circulation pump P is connected in 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 circulation pump P
Is connected to the discharge side.

[0008] The discharge water pipe 3 is disposed adjacent to the lower surface of the rim 11 formed in a protruding shape outside the upper end edge of the opening of the bathtub body 1 and laid along the outer surface of the bathtub body 1; Connection water pipe 32 that communicates main body 31 with each jet port 2
And a pump-side water pipe 33 for communicating the center of the discharge water pipe main body 31 with the discharge side of the circulation pump P.

Then, the discharge water pipe main body 31 and the pump side water pipe 33
The vicinity of the connecting portion is formed as a rim adjacent portion formed in the middle of the circulation pipe R, and the air suction portions 4 are provided on both sides of the connecting portion.
Is formed.

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

In addition, a nozzle 44 is provided in the discharge water pipe main body 31 upstream of the connection portion of the air suction pipe 41 to provide a circulation pump P.
From the nozzle 44 is blown out from the nozzle 44 into the air suction section 4.

The embodiment of the present invention is configured as described above. When the circulating pump P is operated, the bath water in the bathtub main body 1 is sucked into the circulating pump P via the suction water pipe 51, and the pump is operated. The air is pressurized by P and jetted from the nozzle 44 into the air suction section 4. A negative pressure is generated inside the air suction part 4 by the flow of the bath water, and the air is mixed into the bath water by sucking outside air into the air suction part 4 through the air suction pipe 41 by the negative pressure. .

The bath water mixed with air as described above passes through the discharge water pipe main body 31 and the connecting water pipe 32 and is used as a bath water containing air bubbles.
Spouts from the spout 2 into the bathtub body 1.

As described above, since both the bath water and the mixed air are supplied to the jet port by the discharge water pipe 3, separate piping for the air suction pipe is not required, and the piping around the bathtub body 1 is simplified. In addition, the range of positions for drilling holes for piping into the reheating bath kettle drilled on the side wall of the bathtub body 1 is widened, and the piping work is also facilitated.

Further, the air suction part 4 is connected to the rim 11 of the bathtub body 1.
By providing the discharge water pipe main body 31 close to the lower surface, the air suction section 4 is located at a higher position than the water level in the bathtub main body 1, and it is possible to avoid obstruction of air suction by the head of the bath water. A large amount of air can be mixed into the bath.

[0016]

[Effect of the Invention] The base end of the circulation pipe is connected to the suction port of the bathtub body, and the tip is connected to the spout of the bathtub body. A circulation pump is connected in the middle of the circulation pipe, and the bath water flows from the circulation pump. In the bubble-generating bath tub that blows out bubbled bath water from the spout toward the inside of the bathtub body, the middle part of the circulation pipe extending from the circulation pump to the spout is formed in an overhanging manner at the upper edge periphery of the bathtub body. Close to the underside of the rim
By forming a rim proximate part higher than the spout, providing a nozzle in the rim proximate part, and providing an air suction part communicating with the outside air downstream of the nozzle, the air suction part is located The height of the circulating pump can be prevented, so that it is not necessary to set the circulation pump to a high output. Therefore,
It has a power-saving effect, and it is possible to mix sufficient air into the bath water even at a low ejection pressure without noise. In addition, since a long air pipe is not required, the pipe around the bathtub body is simplified, the weight of the pipe can be reduced, and the labor at the time of carrying in can be reduced. Further, the range of the position of the pipe hole for the additional heating bath kettle formed in the side wall of the bathtub body is widened, and the piping work is also facilitated.

Further, since an air suction portion is provided in the circulation pipe so that the hot water mixed with air bubbles can be jetted, the jet port can be made compact.
