334))).

(Problems to be solved by the device) However, the propellers 5, 5 are installed in the water pipe on the long side of the bathtub 1.
Since they are arranged respectively, a pipe diameter that matches the outer shape of the propellers 5 and 5 is required, and the flow pipe arrangement space on the long side of the bathtub 1 must be set wide. Since the cross-sectional area of No. 2 is molded to the required minimum dimension, molding becomes difficult and the water flow efficiency also deteriorates.

In addition, the running water pipe 2 requires two holes for inserting the propeller shafts 4,4, which makes it difficult to seal the water tight, and also has an interlocking mechanism for rotating the two propeller shafts 4,4 that are separated by a motor at the same time. There was a problem that it became complicated.

The present invention has been made to solve the above problems, and an object thereof is to provide a running water generation bathtub having a simple and compact structure and a good running water efficiency by devising an arrangement structure of a propeller and a propeller shaft. To do.

(Means for Solving the Problems) Therefore, according to the present invention, a flowing water pipe is arranged around the outer periphery of a substantially rectangular shaped bathtub when viewed in plan, and the flowing water pipe is provided on both wall surfaces on the short side of the bathtub. Each of the communicating water flow inlet / outlet slits is formed, and a propeller shaft extending along one axis in the short side direction is inserted into one of the water flow pipes on the short side of the bath, and the slit is provided between the propeller shafts. It is characterized in that two propellers for generating water flows in opposite directions are attached to each other.

(Operation and effect of the invention) The present invention inserts a propeller shaft extending uniaxially in the direction of the short side into one of the water flow pipes on the short side of the bathtub, and inserts a slit on the wall surface of the bathtub between them. It is equipped with propellers that generate water flows in opposite directions.

Therefore, the screw can be arranged in the flowing water pipe on the short side having a space in comparison with the long side of the bath, so that the bath becomes compact.

In addition, since the cross-sectional area of the flowing water pipe in this portion is large, the molding is easy, and the screw can be set large so that the flowing water efficiency becomes good.

Further, since the propeller shaft is on one axis, only one through hole for the water flow pipe is required, which facilitates watertight sealing and simplifies the interlocking mechanism for rotating the motor.

Furthermore, since the motor and the interlocking mechanism are integrated in one place, repair work can be easily performed.
