Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jet jet device for a bathtub that mixes water and air to jet jet.

2. Description of the Related Art In recent years, from a health-oriented need, water and air have been mixed and jet-jetted, and a mechanical stimulus has been applied to the surface of a body during bathing to promote blood circulation, thereby recovering fatigue. Is spreading.

FIG. 4 shows a schematic configuration of the jet jet device for a bathtub.

As shown in the figure, a suction pipe mounting bracket 21 for mounting a water suction pipe 22 communicating with a suction port of a pump 23 is fixed to a water suction port 20a of the bathtub 20. A jet nozzle device 25 for attaching a water pipe 24 communicating with a discharge port of a pump 23 is fixed to a jet port 20b of the bathtub 20. 26 is a jet nozzle device
An air supply pipe that supplies air to 25.

With the above configuration, the hot water in the bathtub 20 is sucked into the pump via the water absorption pipe 22, and is sent to the jet nozzle device 25 by the pump 23 via the water supply pipe 24. The pumped hot water is sent to the air line 26
, And jets into the bathtub 20 together with the air bubbles from the jet nozzle device 25.

PROBLEM TO BE SOLVED BY THE INVENTION In such a conventional jet jet device for bathtub, since the pump 23 is located away from the bathtub 20, the long water absorption pipe 22 and the water supply pipe 24 must be provided. In addition, the piping work required a lot of work, and because the piping was long, the vibration of the pump 23 was transmitted, sometimes causing resonance and causing noise.

The present invention solves the above-mentioned problems, and eliminates the need for a suction pipe mounting bracket and a suction pipe, and can reduce the length of a water supply pipe, does not require labor for piping, and reduces vibration noise. It is an object of the present invention to provide a small jet blast device for a bathtub.

Means for Solving the Problems In order to achieve the above object, a jet jet device for a bathtub of the present invention has a bathtub having a water inlet and a jet port, and a pump fixed by a casing disposed in the water inlet. A water supply pipe communicating with the pump, and a jet nozzle device communicating with the water supply pipe and facing the jet outlet, the pump comprising:
The suction port faces the water suction port and is fixed to the bathtub by the casing. Further, the pump is formed by a DC drive brushless motor in which an impeller is integrated.

Effect The pump of the present invention is fixed by the casing with the suction port facing the water suction port formed in the bathtub. Therefore, the pump and the bathtub can also be fixed by the casing, and the pump can be made thinner and smaller. Further, the pipe of the present invention is only a water pipe communicating the pump and the jet nozzle device, which simplifies the pipe work, and eliminates a long pipe, thereby eliminating vibration noise from the pump.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1 and FIG.

As shown in the drawing, a pump 15 formed by a DC drive brushless motor 19 integrally incorporating an impeller is fixed to a water suction port 14 a of the bathtub 14 by a casing 3 of the DC drive brushless motor 19. A pump 15 is provided at the jet port 14a of the bathtub 14.
The jet nozzle device 17 communicating with the water supply pipe 16 communicating with the discharge port of the nozzle is fixed. Reference numeral 18 denotes an air supply pipe that supplies air to the jet nozzle device 17.

Next, a DC drive brushless motor forming the pump 15
The configuration 19 and the fastening configuration of the pump 15 will be described with reference to FIG.

As shown in the figure, reference numeral 1 denotes a cover member attached to the water inlet 14a of the bathtub 14, which is attached to the casing 3 by screwing. Reference numeral 2 denotes an inflow port provided in the cover member 1.
Reference numeral 3 denotes a casing which also serves as a screwing fastening member for the bathtub 14 and the motor unit. Reference numeral 4 denotes a bracket that is screwed to the casing 3 and is formed of a synthetic resin. 5 is a packing provided on both sides of the bathtub 14. Reference numeral 6 denotes a stator resin-molded in the bracket 4, and reference numeral 7 denotes a rotor, which is formed of an alloy resin and has a rotor magnet 7a molded therein. Reference numeral 8 denotes a buried bearing buried in the center of the rotor 7. A shaft 9 rotatably supports the bearing 8 and is fixed by the bracket 4 and the casing 3. Numerals 10 are shaft plates which are arranged at both ends of the bearing 8 and receive sliding of the rotor 7 in the thrust direction. Reference numeral 11 denotes an impeller integrally formed with the rotor 7, which pressurizes the sucked water and sends it to a water pipe 16. 12 is a discharge pipe.

DC drive brushless motor 19 configured as above
Since the rotor 7 is integrally formed with the impeller 11 and the rotor magnet 7a is molded, and the bracket 4 is molded with the stator 6, so that the axial thickness can be reduced. .

In the above configuration, the pump 15 is connected to the bathtub 14 by screwing the casing 3 and the bracket 4 forming the DC drive motor 19.
The pump 15 and the jet nozzle device are connected to the water pipe
Since they are communicated at 16, the water pipe 16 is extremely short. Further, since the brushless DC motor 19 has a small thickness in the axial direction and is miniaturized, the vibration thereof is also reduced, and the vibration noise is reduced in conjunction with the shortening of the water pipe 16.

EFFECT OF THE INVENTION As is clear from the above description of the embodiment, according to the present invention, a bathtub having a water inlet and a jet outlet, a pump fixed by a casing disposed in the water inlet, and the pump And a jet nozzle device communicating with the water pipe and facing the jet port, wherein the pump is fixed to the bathtub by the casing with its suction port facing the water suction port. Since the pump has its suction port facing the water suction port, the pump is fixed to the bathtub by a casing, and no piping other than a water pipe is required, and the length of the pump is extremely short. In addition, the time and labor are not required, and the space for disposing the pump is not required. Furthermore, since the pump is formed by a direct current drive brushless motor in which an impeller is integrally incorporated, it is possible to provide a jet blast device for a bath tub having excellent effects such as reduced vibration and reduced noise.
