[0002]

2. Description of the Related Art Conventionally, there is a type of bath in which bath water is forcibly circulated in order to make bathing comfortable. In this bath, as shown in FIG. 4, a discharge device 2 and a suction device 3 are attached to a bathtub 1 and a discharge port 2a and a suction port 3a are opened on a tank inner side surface 1a. The discharge port 2a and the suction port 3a are communicated with each other through a circulation channel 4, and a circulation pump 5 is connected in the middle of the circulation channel 4. Further, in this bath, an air supply path 6 composed of a pipe or the like is provided outside the tank, and the suction area 2b of each of the discharge tools 2 and the air intake amount adjusting tool 7 are connected by the air supply path 6. The bathtub 1 is provided with a drainage tool 8 on the bottom surface 1b inside the tank, and extends a drainage channel 9 composed of a pipe or the like from the drainage tool 8, or drains naturally from the drainage tool 8 without providing the drainage channel 9. is there. The drainage tool 8
A rubber stopper 10 is provided detachably.

In the bath, when the circulation pump 5 is started, the hot water W in the bathtub 1 is sucked by the suction port 3a of the suction tool 3 and guided to the circulation flow path 4, and then the hot water W is pumped by the circulation pump 5. The pressurized hot water is guided to each discharge device 2 through the circulation channel 4, and each discharge port 2 a

The above bath has the following problems. (A) The area around the bathtub 1 is a place where piping work is difficult because the foundations and walls of the building approach. Therefore, separately drawing out the circulation channel 4 and the drainage channel 9 from the bathtub 1 requires:
A lot of labor is required for construction. Further, providing the suction tool 3 and the drainage tool 8 in the bathtub 1 requires a plurality of holes to be drilled in the bathtub 1 and requires much labor for drilling and mounting the metal fittings 3 and 8. (B) During bathing, a suction port 3a opened on the inner surface 1a of the tank.
In some cases, a part of the body or a towel may be sucked and the suction port 3a may be closed. At this time, in order to separate the sucked object from the suction port 3a, it is necessary to pull the sucked object in the lateral direction away from the suction port 3a. However, it is difficult for the user to sit in the bathtub 1 and apply sufficient force to pull in the lateral direction. Therefore, conventionally, it was not possible to immediately separate the sucked object, which was dangerous.

An object of the present invention is to provide a bath for forcibly circulating a bath water which can shorten the work and facilitate the separation of the sucked water in order to solve the above problem.

[0006]

A first means adopted by the present invention is a bath tub having a discharge port and a suction port opened on the inner surface of the tub,
In a bath forcibly circulating bath water provided with a circulation channel connecting the discharge port and the suction port, and a circulation pump connected in the middle of the circulation channel, the suction port is opened on the bottom surface in the tank. In addition, a drainage channel extends from a position upstream of the circulation pump and lower than a bottom surface in the tank in the circulation channel, and a drainage valve is provided at an appropriate position in the drainage channel.

[0007] The second means adopted by the present invention is a bathtub having a discharge port and a suction port opened on the inner surface of the tank, a circulation channel connecting the discharge port and the suction port, and a circulation channel. In a bath forcibly circulating bath water provided with a circulating pump connected in the middle of the bath, the suction port is opened at the bottom of the tub, and the circulating flow path is upstream of the circulating pump and from the bottom of the tub. That is, a drain port is provided at a lower position, and a drain valve is provided at the drain port.

[0008]

[Function] The suction port is used for both circulation and drainage. Therefore, it is not necessary to provide a drain port in the bathtub separately from the suction port. When the drain valve is opened and the circulating pump is stopped, a drain state is established. When the drain valve is closed and the circulating pump is operated, the bath tub is circulated.

Since the suction port is opened at the bottom of the tank, when a part of the body or a towel is sucked into the suction port, if the sucked part is pulled upward just away from the suction port, the suction port is pulled. Can be separated from It is easier to apply a force to pull the bather upward than in the sideways direction because the bather is in a standing direction.

As shown in FIG. 1, the drain valve 11 can be opened and closed by an electromagnetic operating tool 11a, or can be opened and closed by an operating cable (not shown) extending from an opening edge 1c of the bathtub 1 or the like. An operation type or the like is appropriately selected. When the drain valve 11 is opened and the circulating pump 5 is stopped, a drain state is established. When the drain valve 11 is closed and the circulating pump 5 is operated, the bath tub hot water W is circulated. Therefore, the suction port 13a of the suction tool 13 is used for both circulation and drainage.

When the drainage valve 11 is closed and the circulation pump 5 is operated, the hot water W sucked from the suction port 13a is guided to the circulation pump 5 through the upstream side 4a of the circulation flow path 4. The hot water W pressurized by the circulation pump 5 is guided to each discharge device 2 via the downstream side 4b of the circulation flow path 4 and is jetted into the bathtub 1 from each discharge port 2a.

In this embodiment, the suction port 13a is connected to the tank bottom 1b.
When a part of the body or a towel or the like is sucked into the suction port 13a circulating the hot water W, the hot water W can be pulled right above and separated from the suction port 13a.
Applying force to pull directly upwards is
, The direction can be made easier than in the direction just beside which is the pulling direction of the conventional structure. Further, in this embodiment, since the suction port 13a is provided in the bathtub bottom surface 1b, dust having a high specific gravity can be effectively suctioned and caught by the strainer 18.

In this embodiment, since the suction port 13a of the suction tool 13 is used for both circulation and drainage, there is no need to separately draw out the circulation flow path 4 and the drainage path 9 from the bathtub 1 and the construction is simple. Becomes
