Jet generators 11A, 11B, and 11C that utilize known ejector effects are mounted on the upper and lower two places on the back surface of the front wall and one place on the rear wall of the tank body 1, respectively, and at the front end of each jet generator. Is the nozzle 12A, 12B, 1
2C is facing the inside of the tank. Reference numeral 13 is a bubble generator attached to the bottom wall of the tank body 1, and in this embodiment, it is attached to six places. This bubble generator 13 is a known simple small bubble generator in which a check valve 13A made of a soft thin film rubber is interposed as shown in FIG. 4, and the air E introduced in the direction of the arrow is a surface plate. It is emitted in four directions from a plurality of notched portions 13C provided on the back surface around 13B.

Each of the jet generators 11A, 11B and 1
1C is the corresponding dedicated water pump 14
The discharge ports A, 14B and 14C (hereinafter simply referred to as pumps) are connected to each other in a manner described later. Then, the upper plate 7C of the pump mounted on the lower plate 7B
The air pump 15 installed in the above is connected to each bubble generator 13 through an appropriate pipe as described later.

That is, in this embodiment, as shown in the fluid system diagram of FIG. 5, the discharge ports of the pumps 14A and 14B are
The jet generators 11A and 11B are connected via flow passages 16 and 17 such as an appropriate hose or piping, and the discharge port of the remaining pump 14C is passed through a motor valve 18 for three-way switching and a jet flow generator 19 is used. 11C, and the air pump 15 is connected to each bubble generator 13 via the flow path 20.
Connected with. The three-way switching motor valve 18
Communicates with the flow path 19 except during forced drainage as described later. The jet generators 11A, 11B and 11C are provided with an air suction hole 21 opened at the upper end surface of the tank, a check valve 22 and a flow path 2.
3, 24 and the shared solenoid valve 25 are used for communication.

The suction side of the pump 14C is connected to a drain port 26 provided at the bottom of the tank via a flow path 29 having a heater 27 and a flow switch 28 for preventing heater heating. The suction sides of the pumps 14A and 14B are connected to the flow path between the flow switch 28 and the pump 14C, and a common flow path 31 having a two-way switching motor valve 30 is provided.
Connected through. The motor valve 30 normally maintains the communication state between the passages 29 and 31 except during forced drainage described later.

The remaining forced drainage channel 32 connected to the three-way switching motor valve 18 communicates with an external drainage port. The three-way switching motor valve 18 has a position in which the channels 29 and 19 are communicated with each other and the forced drainage path 32 is blocked, except when forced drainage is performed, as described later. Furthermore,
An overflow discharge port 32 is opened slightly below the air intake hole 21 that is opened at the upper edge of the tank, and the overflowed hot water is naturally drained to the outside through the flow path 33.

The apparatus is equipped with a water level sensor, a temperature sensor, a thermostat, a warning buzzer, etc., and detects various abnormal conditions and issues a warning and / or stop signal to ensure safety and prevent damage to the equipment. I am measuring. In the standby state before the start of treatment, the heater 27 is turned on and the temperature of the treatment water in the bath is preheated to an appropriate temperature by a temperature control member including a temperature sensor.

The upper and lower limb bath apparatus of the present invention is constructed as described above and used as follows. And now
A case of treating the lower limbs of the patient M as shown in FIG. 1 will be described. First, when the touch-type operation panel 6 is operated to move all the pumps, the three-way switching motor valve 18 shuts off the forced drainage channel 32 to connect the flow channels 29 and 19 to each other for other two-way switching. Since the motor valve 30 is placed in a state in which the flow paths 29 and 31 are in communication with each other, the hot water in the tank passes from the drain port 26 through the heater 27 and the flow switch 28, and a part of the hot water flows from the discharge port side of the pump 14C to the motor valve. 18,
After passing through the flow path 19, to the jet generator 11C, the remainder is branched to the pumps 14A and 14B via the motor valve 30, and then supplied to the jet generators 11A and 11B corresponding to the respective pumps. Along with this, the air sucked from the air suction holes 21 by the ejector effect is introduced into each jet generator, and as a result, the jets in which air is mixed from the nozzles 12A, 12B, and 12C are directed from the three directions toward the affected area. Spout and perform well known jet bath treatment. On the other hand, since the air pressurized by the air pump 15 is jetted from the bubble generators 13 in all directions through the flow path 20, it is possible to simultaneously perform the bubble bath treatment.

When only the jet from the nozzle 12A is required for local treatment, for example, calf treatment, if only the drive circuit of the pump 14A is operated and other pumps are stopped. Good. In any case, in order to treat the required part of the affected area, the corresponding pump may be driven or stopped so as to generate a jet flow or bubbles from the required nozzle.

Next, the case where the bath water is discharged after the treatment is completed will be described. In discharging the hot water in the tank, first, the motor valve 18 is operated to connect the forced drainage channel 32 and the flow channel 29 to block the flow channel 19 and at the same time, to remove the motor valve 30.
Is also operated to cut off the connection between the flow paths 29 and 31. Next, when the pump 14C is driven, the hot water in the tank is forcibly discharged to the outside from the drain port 26 through the flow paths 29 and 32. Then, when the drainage passing through the flow path 29 is exhausted, the flow switch 28 senses and stops the operation circuit of the pump 14C and the heater 27, which is a normal means. However, in the present invention, the heater 27 stops the operation. The pump 14C does not stop immediately, but the pump 14C is continuously driven for about 20 seconds after the flow switch 28 is sensed via a timer (not shown), and at the same time, the motor valve 30 is operated to operate between the flow paths 29 and 31. To communicate. Therefore,
For about 20 seconds when the timer expires, the pump 14
Due to the function of C, the residual water in the flow channels 31 and 29 is forcibly discharged. The above flow switch 28
After sensing, the air pump 15 for generating bubbles is also the pump 14C.
By operating in synchronism with the above, the residual water droplets in the air flow path 20 and the bubble generator 13 can be scattered, and the residual water can be completely removed.

As described above, according to the present invention, in the upper and lower limb bath device of the hydrotherapy device, the jet generating member and the bubble generating member are incorporated in a single device, and the jet bath and the bubble bath are operated simultaneously or independently. As a result of forming it so as to obtain, compared to the conventional treatment with a separate and independent device, not only the economic effect but also the movement of the patient between the devices can be omitted, and the installation space can be reduced to about half. It can bring great benefits.

Further, according to the present invention, since the dedicated water pumps are attached to the three jet generators, the strength of the jet flow is lowered even if two or three jet pumps are simultaneously operated as in the conventional case. There are no defects and the effectiveness of treatment is improved.

Further, in the conventional jet bath apparatus, the jet water is supplied to the three nozzles by the single water pump, so that a large number of motor valves for switching the supply flow paths are inevitably required. Since the repair work due to the trouble of the motor valve itself or the trouble of the electric control parts occupies a high ratio in the repair work of the entire device, the total cost is reduced even if the dedicated water pump is equipped as in the present invention. Will never be at a disadvantage compared to the past.

Further, according to the present invention, when the hot water in the tank is forcibly discharged, the jet flow passages are connected to each other for about 20 seconds after the flow switch 28 is sensed until the timer expires. At the same time as forcibly draining the water, the air pump 15 is also operated to scatter the water droplets that have stagnated in the air flow path 20 and the bubble generator 13, so that the residual water after treatment can be greatly reduced, which is hygienic. The effect of can be expected.

In the embodiment of FIG. 1 described above, an example of treatment of lower limbs is shown, but the present invention is applicable to treatment of upper limbs, and at the same time, it is not limited to upper and lower limb bath devices and upper limb bath devices for upper limb treatment and Obviously, it also applies to foot baths as well as whole body baths.

[0025]

According to the upper and lower limb bathing device of the first aspect, the jet generating member and the bubble generating member are incorporated in a single device, and a dedicated water pump is provided for a plurality of jet generating members of the jet generating member. Therefore, even if the operation of one nozzle or two nozzles is switched to the simultaneous operation of three nozzles, the jet strength is not weakened, and a satisfactory satisfaction and therapeutic effect can be obtained, and at the same time, the whirlpool bath and air bubbles can be obtained. Since the baths can be treated simultaneously or independently by a single upper and lower limb bath device, not only the advantages of economical and installation space but also improvement of treatment efficiency can be expected.

According to the upper and lower limb bath device of the second aspect, since the jet flow supply passages are communicated with each other for a predetermined time after the flow switch is sensed during forced drainage to remove residual water in the flow passages, many devices are connected to each other. The drained hot water in the pipeline and bubble generation board does not remain, and hygienic water treatment can be effectively performed.
