DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the accompanying drawings, in which a massage device for a bathtub having a massage suction device and a bathtub device having the same are described.

(Embodiment 1) FIG. 1 is a schematic diagram showing a bathtub apparatus according to Embodiment 1 of the present invention.

Referring to FIG. 1, 1 is a bathtub, and 2 is a massage device for a bathtub.

The bathtub massage device 2 includes a bathtub water circulation loop 3 composed of piping, a circulation pump 4, a massage suction device 5, and a controller 6.

The bathtub water circulation loop 3 is for taking out the bathtub water from the bathtub 1 and returning it to the bathtub 1 again. The bathtub water circulation loop 3 is connected to the bathtub water suction port 7 and the bathtub water return port 8 of the bathtub 1 as appropriate. ing. In the bathtub water circulation loop 3, a circulation pump 4 and a massage suction device 5 are provided.

The massage suction device 5 is closed by a part of the human body such as a bather, and has a suction opening 5a for sucking a part of the human body by an internal negative pressure, and a bathtub water from the bathtub 1 inside. It has a bathtub water inlet 5b for drawing in, and a bathtub water outlet 5c for discharging the bathtub water inside to the outside. Then, in the massage suction device 5, bathtub water is drawn in through the bathtub water inlet 5 b by the circulation pump 4 as a negative pressure mechanism with the suction opening 5 a closed by a part of the human body. A structure is provided in which a negative pressure is applied when water is discharged from the bathtub water discharge port 5c.

The controller 6 includes a microcomputer for controlling the entire bathtub apparatus, and controls the operation of the circulation pump 4 to apply a negative pressure to the inside of the massage suction device 5.

Reference numeral 9 denotes a suction pipe for connecting the bath water inlet 7 to the bath water inlet 5b of the massage suction device 5, and reference numeral 10 denotes a circulation pipe which communicates with the bath water outlet 5c of the massage suction device 5. A suction pipe 11 communicates and connects the suction port of the pump 4, and a pipe 11 connects the discharge port of the circulation pump 4 and the bathtub water return port 8.

In operation, when the circulation pump 4 is operated and the suction opening 5a of the massage suction device 5 is closed by a human body, the bath water in the bath tub 1 is changed from the bath tub 1 to the bath tub water suction port 7.
→ Suction pipe 9 → Bath water inlet 5 of massage suction device 5
b → Suction device 5 for massage → Suction device 5 for massage
Bath water discharge port 5c → suction pipe 10 → circulation pump 4 → bath water return pipe 11 → jet jet nozzle 13 (bath water return port 8) → tub 1 circulates in a bath water circulation loop.

In this bathtub water circulation loop, a negative pressure is applied to the inside of the massage suction device 5, so that a part of the human body, such as the back, which closes the suction opening 5a is sucked by the negative pressure, resulting in bathing. The person can receive a required suction massage (massage by sucking a part of the human body) while taking a bath.

(Embodiment 2) In Embodiment 1, the massage suction device 5 performs only suction massage for sucking a part of the human body. In Embodiment 2,
A jet jet is ejected from the massage suction device 5 to the human body, so that the human body is subjected to jet massage (massage by jet jet) in addition to the suction massage. As a result, the human body performs suction massage and jet massage. The suction jet massage is performed.

In this case, in the second embodiment, a conventional jet jet can be jetted from the bathtub water return port 8 of the first embodiment by a jet jet nozzle.

The second embodiment will be described below with reference to FIGS. The illustration of the controller 6 is omitted (the same applies to the following embodiments).

In FIG. 2, reference numeral 12 denotes a jet air suction port, and reference numeral 13 denotes a jet ejection nozzle provided in the hot water return port 8 of the first embodiment.

The jet air suction port 12 and the jet jet nozzle 13 are connected via a jet air pipe 14. The bath water inlet 7 and each massage suction device 5 are connected via a suction pipe 9. Each massage suction device 5 and the circulation pump 4 are connected via a suction pipe 10. The circulation pump 4 and the jet jet nozzle 13 are connected via a bathtub water return pipe 11. The circulation pump 4 also functions as a negative pressure mechanism that suctions bath water in the massage suction device 5 to apply a negative pressure, as described later. When only suction massage is performed by applying a negative pressure in the massage suction device 5, the negative pressure mechanism is not limited to the circulation pump 4, but may be a vacuum pump or a decompression pump. In the second embodiment, the circulation pump 4 is used as a negative pressure mechanism to enable suction jet massage using both suction massage and jet massage.

When the circulation pump 4 is driven, the bath water flows through a circulation loop indicated by an arrow. That is, when the circulation pump 4 is driven, the bathtub water is changed from the bathtub 1 to the bathtub water inlet 7 →
Suction pipe 9 → each massage suction device 5 → suction pipe 10 →
Circulation pump 4 → bath water return pipe 11 → jet jet nozzle 13 → first circulation loop of bath tub 1 and bath tub 1 → each massage suction device 5 → suction pipe 10 → circulation pump 4 → bath tub water return pipe 11 → jet jet The nozzle 13 circulates through a second circulation loop of the bathtub 1. Here, when each of the massage suction devices 5 is closed, the bathtub water is
Circulate only in the first circulation loop.

Next, referring to FIG.
Will be described.

A cylindrical bathtub bolt 17 is attached to the opening 15 in the side wall of the bathtub 1 via an annular bathtub packing 16. The tip of the bathtub bolt 17 projects outside the bathtub 1. A bathtub joint 18 is attached to the outer periphery of the tip of the bathtub bolt 17.
Is screwed. The bathtub joint 18 includes an inner tube 19 and an outer tube 20 on the side of the bathtub bolt 17 (front side), and a tube portion 21 for connection to the suction pipe 9 and a tube portion for connection to the suction pipe 10 on the rear side. 22. The inner cylinder 19 and the cylinder 21 communicate with each other, and the outer cylinder 20 and the cylinder 22 communicate with each other. In this massage suction device 5, the opening of the bathtub bolt 17 is the suction opening 5a, and the inner tube 19 and the tube portion 21 are the bathtub water inlet 5b for drawing the bathtub water from the suction pipe 9 into the inside.
The outer tube 20 and the tube portion 22 constitute a bath water outlet 5c for discharging the internal bath water to the external circulation pump 4. Further, the inner cylinder 19 also constitutes a jet jet part.

In the above configuration, the bathtub massage apparatus of the second embodiment includes one or more (in the embodiment, a plurality of, the same applies hereinafter) massage suction devices 5 and a circulation pump 4. And the circulation pump 4
When the massage suction device 5 is closed, it also functions as a negative pressure mechanism for drawing the inside of the massage suction device 5 to a negative pressure.

Now, even if the circulation pump 4 is driven, when the suction opening 5a of the massage suction device 5 is not closed, as described above, the bath water in the bath tub is connected to the first circulation loop. It circulates with the second circulation loop, and in this circulation, the jet jet is jetted from the jet jet nozzle 13.
However, when the opening 5a of the massage suction device 5 is closed by the human body 23 such as the back of a bather, bathtub water in the bathtub 1 circulates in the first circulation loop.

In this case, when the massage suction device 5 is closed by the human body 23, the massage suction device 5 in the first circulation loop becomes negative due to the pump action of the circulation pump 4, that is, the bathtub water suction action. Pressure. As a result, a part of the human body 23 is drawn into the massage suction device 5. Further, when the bathtub water sucked from the bathtub water suction port 7 exits from the inner cylinder 19 to the outer cylinder 20 in the massage suction device 5 as shown by a thick solid line in FIG. The water is jetted into the bathtub 1 by the pump action, whereby the bathtub water is jetted to the human body 23 in a jet jet state. In this case, comparing the cross-sectional area of the cylindrical portion 21 with that of the inner cylinder 19, the cross-sectional area of the inner cylinder 19 is small, so that the water pressure of the inner cylinder 19 increases, and a jet jet is more easily formed.

Therefore, the bather can receive a relatively strong suction massage, such as receiving acupressure by the stimulus when a part of the back is drawn into the massage suction device 5, and jet jet flow. The bathtub water can receive a jet massage even with the stimulus that hits its back, so the synergistic effect of both massages gives a new sense of massage (combination massage of both massages: suction jet massage) Can be Describing this synergistic effect, in the above state, the bather enters a massage state in which the back meat is pulled by suction massage and blood circulation is promoted. Furthermore, when a jet massage with a warm jet jet is performed on the stretched portion of the back meat, stimulation of blood vessels and the like on the back becomes stronger and blood circulation is further promoted, and as a result, only a suction massage or a massage using only a jet massage is performed. Can also receive a more effective massage.

(Embodiment 3) In the bathtub massage apparatus according to Embodiment 2 described above, especially at the beginning of operation, the circulating pump 4 sucks the air in the suction pipe 10 to be in a so-called air dust state. When the circulating pump 4 is in the air-gathered state, the suction action of the massage suction device 5 is reduced. The third embodiment prevents this.

The third embodiment will be described below with reference to FIGS.

In the bathtub massage apparatus according to the third embodiment, in order to prevent the air stagnation state, two first and second three-way valves 26 and 27 are used to form the suction pipe 10.
Is switched from the bathtub water circulation loop to the circulation loop for air release to release the air in the suction pipe 10, and when the air release in the suction pipe 10 is completed in this mode, the bathtub is operated by the three-way valves 26 and 27. By switching to the water circulation loop, the operation can be shifted to the normal operation mode (operation mode for performing suction jet massage) by the circulation pump 4. Therefore, the bathtub massage apparatus according to the third embodiment includes an air vent valve 24, an air separator 25, and first and second three-way valves 26 and 27, which are brought into a state shown in FIG. Connected with.

In the air bleed operation mode, as shown in FIG.
0, and the switching pipe 32 is connected by the second three-way valve 27.
And 33 are connected. Thereby, each massage suction device 5 → suction pipe 10 → switching pipe 32 → circulation pump 4 →
Switching pipe 29 → air separator 25 (→ air release valve 2
4: The air separated from the bath tub water is removed by the air separator 25) → the switching pipe 28 → the first three-way valve 26 → the switching pipe 30 → a circulation loop (air release circulation loop) A of each massage suction device 5; , Bathtub 1 → bathtub water inlet 7 → switching pipe 33 → second three-way valve 27 → switching pipe 32 → circulation pump 4 → bathtub water return pipe 11 → jet jet nozzle 13
→ A circulation loop B (path for performing a normal jet massage by a jet jet) of the bathtub 1 is formed. Thus, in this air bleeding operation mode, air bleeding in the suction pipe 10 is performed in the circulation loop A, air turbulence in the circulation pump 4 is prevented, and normal massage by a jet jet is performed in the circulation loop B. The suction jet massage using the massage suction device 5 is not performed.

When the air in the suction pipe 10 is thus vented to some extent, the two-way valves 26 and 27 are switched as shown in FIG. 5 to shift to the normal operation mode.

In FIG. 5, the circulation loops A and B are both eliminated, and the bathtub 1 → bath water suction port 7 → switching pipe 33 → second pipe.
Three-way valve 27 → switching pipe 31 → first three-way valve 26 → switching pipe 30 → each massage suction device 5 → suction pipe 10 → switching pipe 32 → circulation pump 4 → bathtub water return pipe 11 → jet ejection nozzle 13 → A bathtub water circulation loop (path for performing a suction jet massage using the massage suction device 5 and a normal jet massage using the jet ejection nozzle 13) C as the bathtub 1 is formed. This circulation loop C
Has a configuration similar to that of FIG.
3 forms the suction pipe 9. Since the circulation loop C has already been described with reference to FIG. 2, the description is omitted.

Therefore, in the third embodiment, the air in the suction pipe 10 is evacuated in the air bleeding operation mode, so that the air circulation of the circulation pump 4 can be prevented.

(Embodiment 4) In Embodiment 4, the acupressure mechanism is provided so that a bather can selectively move the acupressure mechanism. The massage by the acupressure mechanism in the massage suction device 5 is referred to as acupressure massage. Therefore, bathers
By receiving the acupressure massage by the acupressure mechanism, it is possible to enjoy bathing.

Hereinafter, the fourth embodiment will be described with reference to FIGS.

In the bathtub massage apparatus of the fourth embodiment, the air release valve 24, the air separator 25, the first three-way valve 26, the second three-way valve 27, and the switching pipes 28 to 33 are provided.
This is the same as that of the third embodiment, and is shown in FIG. 7 in an air bleeding operation mode in which air bleeding by the circulation loop A and normal jet massage by the circulation loop B shown in FIG. 6 are performed. In addition to the normal operation mode of performing the suction massage by the circulation loop C and the normal jet massage, the operation mode of performing the suction massage, the normal jet massage, and the acupressure massage shown in FIG. .)have.

Therefore, the fourth embodiment has the two-way valve shown in FIGS. 6 to 8 and the acupressure mechanism provided with the acupressure piston shown in FIGS. 9 and 10.

First, referring to FIGS. 6 to 8, reference numeral 34 denotes a two-way valve. The two-way valve 34 is connected to each of the massage suction devices 5 via a switching pipe 35a, and is connected to the bathtub water return pipe 11 via a switching pipe 35b.

In the air release operation mode, a circulation loop A and a circulation loop B are formed as shown in FIG. 6 by controlling the first three-way valve 26 and the second three-way valve 27, respectively. The two circulation loops A and B have already been described, and a description thereof will be omitted. In the normal operation mode, the first three-way valve 2
The circulation loop C is formed by the control of each of the second and third three-way valves 27 as shown in FIG. The circulation loop C has already been described, and a description thereof will be omitted.

In FIGS. 6 and 7, the switching pipes 35a and 35b are disconnected under the control of the two-way valve 34.

In the acupressure additional operation mode, as shown in FIG. 8, the control of the first three-way valve 26 and the second three-way valve 27 is the same as in FIG. 3
5b. Thus, a circulation loop D for driving the acupressure piston is formed. The circulation loop D is composed of the circulation pump 4 → bath water return pipe 11 → switching pipe 35b → two-way valve 34 → switching pipe 35a → massage suction device 5 (piston driving for finger pressure) → suction pipe 10 → shiatsu massage by circulation pump 4 This is the route to perform.

The structure of the massage suction device 5 for performing the acupressure will be described with reference to FIGS. 9 and 10. The massage suction device 5 has a bathtub packing 16, a bathtub bolt 17, and a bathtub joint 18. The bathtub joint 18 has a cylindrical portion 36 connected to the suction pipe 10 on the side.
And a tubular portion 37 connected to the suction pipe 9, a tubular portion 38 connected to the switching pipe 35 a on the rear side, and a tubular portion 3.
8, a piston 39 for acupressure, a coil spring 40, an O-ring 41, and an annular piston stopper 42 are provided. The acupressure piston 39 has a hole 43 with a small pressure release at its tip.

In the state of the circulation loop D, the bath pump water is supplied to the switching pipe 35 by the circulation pump 4 under a predetermined pressure.
b → spouted into the acupressure piston 39. The acupressure piston 39 causes the coil spring 4
9 is pressed inside the bathtub 1 from the state of FIG. 9 to the state of FIG. As a result, the back side of the human body 23 is pressed by the acupressure piston 39 and receives acupressure massage. When the two-way valve 34 is controlled to cut off the circulation loop D, the acupressure piston 39 returns from the state of FIG. 10 to the state of FIG. Therefore,
When the two-way valve 34 is controlled to shut off and form the circulation loop D, the acupressure piston 39 repeats the states shown in FIGS. 9 and 10, so that the bather repeatedly presses the back side, and Good, Shiatsu.

Accordingly, in the case of the fourth embodiment, the air is bleed in the circulation loop A in the state of FIG. 6, and the normal jet massage is performed by the jet jet nozzle 13 in the circulation loop B.
In addition to the suction massage by the massage suction device 5 in the circulation loop C and the normal jet massage by the jet ejection nozzle 13 in the state of FIG. 8, the suction massage in the circulation loop D and the normal jet massage by the jet ejection nozzle 13 in the state of FIG. Shiatsu massage can be received by the acupressure piston 39, so that bathing can be enjoyed more comfortably.

(Embodiment 5) In the normal operation mode described above, since the second three-way valve 27 is always fully open, the negative pressure in the massage suction device 5 is constant, and therefore, the intensity of the massage is increased. Is constant. In this case, if the strength can be changed in strength, the massage effect can be further improved. Therefore, in the fifth embodiment, the second three-way valve 27 is used as negative pressure control means for controlling the magnitude of the negative pressure in the massage suction device.
By fully opening and fully closing the three-way valve 27, the strength of the massage can be adjusted strongly.

Embodiment 5 will be described below with reference to FIGS. 11 and 12.

The bathtub massage apparatus of the fifth embodiment has an air release valve 24, an air separator 25, a first three-way valve 26, a second three-way valve 27, as in the third embodiment.
Using each of the switching pipes 28 to 33, air bleeding in the circulation loop A and massage by a jet jet in the circulation loop B are performed in the air bleeding operation mode as shown in FIG.
As shown in FIG. 5, suction jet massage and normal jet massage in the circulation loop C can be performed in the normal operation mode.

In the fifth embodiment, in addition to this, as shown in FIG. 11, the second three-way valve 27 is controlled so that the switching pipes 30, 32, and 33 are cut off from each other and circulated. A loop E is formed. However, the switching pipe 32 and the suction pipe 10 are directly connected without going through the second three-way valve 27. In the circulation loop E, even if the circulation pump 4 is driven, bathtub water is not sucked from the bathtub water inlet 7 but is sucked only from the massage suction device 5. Therefore, the circulation loop of the bathtub water is composed of the massage suction device 5 → the suction pipe 10 → the switching pipe 3
2 → circulation pump 4 → bath water return pipe 11 → bath 1 → massage suction unit 5 is a circulation loop. Therefore, a strong negative pressure is applied inside the massage suction device 5,
The bather is more strongly sucked on his back side.

This will be described with reference to FIG.

FIG. 12 shows the air bleeding operation mode, which is the state shown in FIG. The negative pressure in the massage suction device 5 in this air release operation mode is zero.

FIG. 12 shows a normal operation mode in which the second three-way valve 27 is fully opened, which is the state shown in FIG. At this time, the opening of the second three-way valve 27 is fully open. Therefore, bathtub water is sucked not only from massage suction device 5 but also from bathtub water suction port 7. Therefore, the negative pressure in the massage suction device 5 is P1. Assuming that the suction force for the bather by the negative pressure P1 is, for example, “weak”, the strength of the suction jet massage thereby is “weak”.

FIG. 12 shows the normal operation mode in which the second three-way valve 27 is fully closed. However, the state shown in FIG. 11, that is, the opening of the second three-way valve 27 is fully closed. Therefore, bathtub water is sucked only from massage suction device 5,
The negative pressure in the massage suction device 5 is P2 (> P1), and the suction force is "strong", that is, the intensity of the massage is "strong".

In FIG. 12, and are repeated, which means that the massage intensity is repeated “strongly”. By this, the bather, until then, simply has its back side sucked with a certain intensity,
In this state, from a massage in which a jet jet of bathtub water having a certain strength is merely applied, a massage in which the suction strength and the jet jet change together is received, and a more effective massage can be enjoyed.

Further, by adjusting the opening of the three-way valve, the strength of the suction force can be adjusted.

Therefore, in the fifth embodiment, the air bleeding operation mode, the first normal operation mode in which the massage strength is constant, that is, the second three-way valve 27 is always fully open, and the massage strength can be changed to a strong or weak level That is, the second three-way valve 27
A second normal operation mode in which the opening and closing of the three-way valve are repeated by adjusting the opening degree of the three-way valve, and a third normal operation mode in which the medium-strength suction force is adjusted by adjusting the opening degree of the three-way valve. With
In the second and third normal operation modes, the massage effect is changed depending on the bather and the massage effect can be further enhanced depending on the bather.

(Embodiment 6) In Embodiment 5 described above, as shown in FIG. 12, at the time of transition from the air release operation mode to the normal operation mode in which the second three-way valve 27 is fully opened, the second three-way valve 27 In the normal operation mode in which full open and full close are repeated, the change of the negative pressure is abrupt at the time of transition from the original to the original. Therefore, for a bather, since the suction force in the massage suction device 5 changes rapidly, pain may be felt physically.

Therefore, in the sixth embodiment, the buffer tank 4
By arranging 4 in any one of the pipelines, a change in suction force at the time of mode transition is buffered so as not to change suddenly, so that the pain of the bather can be reduced.

Hereinafter, the sixth embodiment will be described with reference to FIGS. FIG. 13 corresponds to FIG.
FIG. 14 corresponds to FIG. 5, and FIG. 15 corresponds to FIG. In these figures, reference numeral 44 denotes a buffer tank. As in the fifth embodiment, the sixth embodiment has an air bleeding operation mode, a normal operation mode in which the massage intensity is constant, and a strong and weak operation mode in which the intensity of the massage can be varied.

In the sixth embodiment, the buffer tank 4
For example, when the second three-way valve 27 is switched between fully open and fully closed in the strong / weak operation mode, the change in the negative pressure is moderated by the buffer tank 44, that is, the change in the suction force is moderated. So as not to give the bather any sensational pain.

The operation of the buffer tank 44 will be described.
The lower part of the buffer tank 44 contains suction bath water from the suction pipe 10 and the upper part contains air. Now, when the first three-way valve 22 and the second three-way valve 23 are in the valve switching state corresponding to the air bleeding operation mode as shown in FIG. 13, they correspond to the normal operation mode as shown in FIG. When the valve is switched, the suction force of the circulating pump 4 is applied to the bath water in the buffer tank 44, and the bath water in the buffer tank 44 is drawn by the switching pipe 32. The bath water in the massage suction device 5 is not immediately drawn, but only the bath water in the buffer tank 44 is drawn first. At this time, since the water level in the buffer tank 44 decreases, the air pressure decreases, so that the water level in the buffer tank 44 does not decrease.
The bath water in the massage suction device 5 is drawn through 0. Therefore, even if the operation state is switched from the air release operation mode to the normal operation mode in which the second three-way valve 23 is fully opened, the negative pressure in the massage suction device 5 rapidly changes as shown by the broken line in FIG. Instead, it changes gradually as shown by the solid line in FIG.

Next, the first three-way valve 26 and the second three-way valve 2
7 is switched from the normal operation mode in which the second three-way valve 27 is fully opened as shown in FIG. 14 to the normal operation mode in which the second three-way valve 27 is fully closed as shown in FIG. For this reason, the negative pressure in the massage suction device 5 in FIG. 16 does not change abruptly as shown by a broken line, but changes slowly as shown by a solid line. As described above, in the sixth embodiment, the negative pressure in the massage suction device 5 does not rapidly change when the operation mode is switched, but changes slowly, so that the pain on the bodily sensation is relieved and the massage effect is further improved. .

(Embodiment 7) A bather can receive a suction massage by closing his / her back with a massage suction device 5 and bringing the inside thereof into a negative pressure state. In this case, the bather may be in a posture in which the whole of the massage suction device 5 cannot be closed. Then, negative pressure is less likely to be applied to the inside of the massage suction device 5, so that a required massage cannot be received. Further, when the circulation pump 4 is operated in a state where the massage suction device 5 at a high position is not closed, there is a problem that air is sucked from the circulation pump 4 and the circulation pump 4 runs idle. Further, there is a case where the user wants to receive acupressure massage which stimulates by pressing a jar of a stiff part of the body like acupressure.

Therefore, in the seventh embodiment, the bather can easily receive a required massage by the massage suction device 5 and the function of the circulation pump 4 is not affected. The bather can press the pot to receive stimulation.

The seventh embodiment will be described below with reference to FIGS. In these figures, a backrest is provided on the massage suction device 5, and among them,
