Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot bath for improving blood circulation in the foot of a physically handicapped person.

[0002]

2. Description of the Related Art For example, in a facility for the elderly, etc. with severe physical disabilities, there is a mechanical bathing turn lifter that can secure a sitting position, and the bath can be taken under the care of a caregiver, but in the living room. If only the feet can be soaked in warm water, the person with a disability can take a foot bath at any time to improve the blood circulation in the foot, and contribute to sleep and physical and mental stability.

[0003] Conventionally, a device for recovering fatigue from a foot bath, relieving neuralgia, muscle pain, and relieving neck and shoulder stiffness due to blood circulation recovery is disclosed in, for example, JP-A-59-115046 and JP-A-56-. It is known from Japanese Patent No. 47651.

However, the invention (invention) disclosed in the above publication has a complicated mechanism such as jet of water jet, vibration by a vibrator, etc. Therefore, not only is the installation troublesome, but the operation is troublesome as well. You cannot operate properly.

[0005]

DISCLOSURE OF THE INVENTION The present invention solves the above problems and enables anyone to easily take a foot bath with a simple mechanism and a simple operation.

[0006]

That is, according to the present invention, a centrifugal pump is connected to a foot bath via a pressure hose, and the pump and the foot bath are connected via a pressure hose, and the centrifugal pump is connected to the centrifugal pump. The rotation angle α of the blades of the liner provided is set to 120 to 130 °, and the hot water in the foot bath is circulated by causing the hot water in the foot bath to be absorbed and discharged by the centrifugal pump through the pressure resistant hose by the operation of the centrifugal pump. At this time, the rotation angle of the blades of the liner causes water friction due to turbulent flow in the discharged hot water, and the foot bath is installed in a recess such as a moat kotatsu. It is what

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Since the present invention is constructed as described above, in order to use it, first, the foot bath 1 is set at a predetermined position (for example, as shown in FIG. 1, a recess 8 provided on the floor). Installed and connected to the centrifugal pump 2 by pressure resistant hoses 3 and 4. Further, the centrifugal pump 2 is connected to a power source (not shown). The flow rate adjusting valves 5 and 6 are attached as described above, and the preparation is completed.

Therefore, warm water of about 40 ° C. is added to the foot bath 1 for 8 hours.
By pouring about 0%, opening the flow rate adjusting valves 5 and 6, and closing the switch (not shown), the centrifugal pump 2 starts rotating, hot water is absorbed from the water intake port 10 and discharged from the discharge port 14. The hot water is jetted into the foot bath 1. At this time, in the present invention, the rotation angle of the tip of the blade 15 of the liner 11 of the centrifugal pump 2 is 120 to 130 °, which is normally that of the centrifugal pump (10 to 30 °). Since the angle is much larger than that of (°), a backflow phenomenon occurs in the water flow, and as a result, friction due to a large resistance is generated in the water flow and turbulence occurs.

Therefore, when the foot is inserted into the foot bath 1, the above-mentioned water flow acts on the foot, so that a massage effect due to friction is obtained in addition to the effect of the warm bath, and as a result, blood circulation in the foot is improved. ..

Thus, improving blood circulation in the foot not only increases the body temperature of the foot, leads to a good night's sleep, and contributes to the stabilization of the mind and body. In this case, the legs are swollen and tired easily, but this is also extremely effective.

Further, the friction of the water flow due to a large resistance causes a turbulent flow. As a result, the temperature of the hot water does not decrease, but rather rises. Therefore, a heat source for keeping warm water is not required.

For example, a three-phase motor 450 watts, 1 /
Using a self-priming centrifugal pump with a 2-hp motor,
The foot bath according to the invention was operated. Put 15 ℃ water in the foot bath,
When it was circulated through a centrifugal pump, the temperature rose to 40 ° C.

[0016]

As described above, according to the present invention, the foot bath and the centrifugal pump are connected to circulate hot water, and at that time, the rotation angle of the blade of the liner of the centrifugal pump is 120 to 1
By setting it at 30 °, friction due to a large resistance is generated in the water flow and turbulence is generated. Therefore, the foot inserted in the foot bath is
Blood circulation is improved. Further, in the present invention, the temperature of the circulating hot water gradually rises due to the friction of the water, and therefore a heat source for maintaining the temperature of the hot water is not required, which is economical.

Further, the present invention is far superior to the conventional ones in that the mechanism is simple, it can be easily installed, and anyone can operate it easily.
