2. Description of the Related Art Recently, various bathtubs have been proposed for the purpose of health and beauty. Most commonly, air bubbles are generated in the bathtub together with the jet water flow, aiming at the massage effect by rupture of bubbles and cavitation.
In addition, a water flow is generated by a screw in the bathtub,
When bathing, a human body is used as a flag body to generate a Karman vortex, and by utilizing the fluttering phenomenon that occurs when this Karman vortex is generated, it is also proposed to apply intermittent vibration to the subcutaneous fat and muscles of the bather. ing. Furthermore, a partition plate is provided at the bottom of the bathtub to form a two-tank type, the lower tank is a circulating tank, and the water refluxed through the lower tank is generated by a screw rotated by a motor,
A bathtub in which the water stream is directly applied to the body has also been proposed.

However, in the conventional jet bathtub, the diameter of the suction port (for returning to the pump) through which the bath water exits the bathtub is small, and the hair is drawn into the suction port and drools. There is a risk that. If the jet and suction ports are placed on the same surface, the pump and bathtub piping will be short, but on the other hand, the water flow going and returning will interfere with each other,
The massage effect is weak. Although there are multiple jets, each jet is small and there is a massage effect that the water flow partially hits, but since the water flow is not concentrated, the fluttering massage effect cannot be expected. Also, if you wanted to concentrate more strongly, you had to bring your body closer to the spout. In addition, in the conventional circulating bathtub, the drive source is directly connected to the bathtub, which causes noise to the bather. Furthermore, since the discharge port is fixed, in order to select and massage the body part, the posture had to be changed, and therefore the bathtub had to be enlarged. Further, the strength of the jet flow cannot be changed unless the rotational speed of the drive source is electrically reduced or the rotational speed ratio between the drive source and the drive shaft is changed. Moreover, since the drive shaft is fixed, it is not possible to easily change the direction of the water flow. In addition, the drive system is unique and cannot be provided inexpensively in terms of production. In the conventional jet bathtub, when the pipe flow path is long, hot water may accumulate in the return pipe and the flow velocity may be reduced, and it is necessary to clean the pipe.
However, cleaning was difficult because the piping was thin. Furthermore,
Some conventional jet bathtubs have a net inside the bathtub that has the function of removing large dust, but the purifying function is provided inside the independent pump unit or outside the bathtub near the bathtub. , And means for maintenance of the tube of the purifying device and the purifying device were required. Further, even if the flow of the water flow becomes weak due to the dirt inside the purifying device, and eventually the ejection speed into the bathtub becomes weak, there is no choice but to remove the dirt from the purifying device to recover it.

[0004]

In order to solve the above-mentioned problems, the present invention provides (1) a bathtub and a detachment disposed in the bathtub in parallel with the bottom of the bathtub at a predetermined distance from the bottom of the bathtub. A possible partition plate, a jet port that jets out a jet water flow that flows from the front of the bathtub toward the rear above the partition plate, and the fluid that flows between the bottom of the bathtub and the partition plate behind the bathtub. A circulation path that circulates the water toward the front of the bathtub, a suction port that is provided on the same plane as the jet outlet at the end of the circulation path, and is disposed outside the bathtub between the jet outlet and the suction port. And a means for opening and closing with respect to each of the injection ports, further comprising: 2) controlling the opening and closing of the means for opening and closing, A means for selecting and switching the ejection position and the number of ejections, or (3) one of the plurality of ejection openings has a larger diameter than other ejection openings, or (4) the above The length of the straight pipe section from the pump to the jet outlet is made longer than the diameter or the length of the diagonal line of the jet outlet, or (5) the swirling flow is provided in the swirl path in the bathtub. It is characterized by having a bathtub water purifying device that closes or opens the path.

The jet water flow directly acts to obtain a massage effect, and the jet water flow smoothly circulates in the bathtub, so that a large massage effect and slimming effect due to the fluttering effect can be obtained. The water inlet to the pump comes under the partition plate, the diverting port is wide and the flow velocity is weaker than the suction port, and the circulatory route is long.Therefore, if you accidentally dive, hair etc. may be sucked and drown. You can avoid sex. Since the partition plate can be removed to clean the lower tank of the partition plate, the circulation path can be kept clean, which is hygienic. It should be noted that if the partition plate is separated into a plurality of sheets instead of one sheet, it is easier to clean. Since the ejection port and the suction port are on the same surface, the connection with the pump is short and the installation area can be made compact. Since it is not necessary to connect the drive system directly to the bathtub, the noise and vibration generated by the drive system need not be introduced into the bathroom, and you can feel comfortable and massage. Further, since the purifying device is provided, the bath water can be kept clean, and the massage effect and slimming effect can be obtained hygienically and comfortably. Moreover, when purification is not necessary, a strong water flow can be obtained, and a large massage effect can be expected.
