DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower apparatus for a bathtub which is used to massage a shoulder by giving a strong jet of shower water to the shoulder while taking a bath.

[0002]

2. Description of the Related Art Heretofore, the applicant of the present invention has previously filed a Japanese Patent Application No. 5-678 for this type of shoulder rest shower apparatus. In this method, a shoulder pad nozzle block having two shoulder pad nozzles for spraying shower water toward a shoulder is placed and fixed on an upper surface of a backrest side of a bathtub flange, and a pressurized circulation pump is attached to a wall surface of the bathroom. The pressure circulating pump and the nozzle block for shoulder contact are connected by a discharge hose, and a suction hose connected to the pressure circulating pump is introduced into the bathtub.

[0003]

When using such a shoulder shower device, a bather taking a bath in the bathtub positions his head between the two shoulder nozzles, and sprays from the shoulder nozzle. The shower water is applied to the bather's shoulder to massage. However, when the head is inserted between the two shoulder-applying nozzles, the pipe hits the pipe connecting the two shoulder-applying nozzles, causing a problem that the head is painful and uncomfortable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to stably place a bather's head on a concave portion of a case and comfortably hold a shoulder. An object of the present invention is to provide a shower device for a shoulder bath of a bathtub that can massage.

[0005]

In order to achieve the above object, the present invention provides a shower apparatus for shoulder bath of a bathtub in which two shoulder nozzles 2 for spraying shower water toward a shoulder are connected by piping. The formed shoulder support nozzle block 3 is fixed above the back side of the bathtub 4, and the hot water in the bathtub 4 is supplied to a pressurized circulation pump 6.
In the shower device for shoulder bath of the bathtub, which is supplied to the nozzle block 3 for shoulder pad, the nozzle block 3 for shoulder pad is stored in the case 16 and the curved surface of the human head is placed on the front side of the case 16. A recessed curved portion 17 having a curved surface is formed, and a case in which the shoulder block nozzle block 3 is stored.
The base 16 is attached to the wall surface 5 on the flange 10 of the bathtub 4 .

[0006]

According to the above construction, a bather sitting in the bathtub 4 places his head on the concave portion 17 of the case 16 between the two shoulder pads 2 and the shower water from the shoulder pads 2. By spraying, shoulder water can be massaged by applying shower water to the shoulder. At this time, by placing the bather's head on the concave portion 17 of the case 16, the head can be contacted and massaged without discomfort.

With the spacer member 12 attached, the fitted portion 34 of the shoulder contact nozzle block 3 is fitted to the fitting portion 41 of the spacer member 12 so that the bolt insertion hole 35 and the bolt insertion hole 43 are aligned with each other. 3
Bolts 36 are inserted through 5, 43, and nuts 37 are screwed into the tips of the bolts 36, and the shoulder block nozzle block 3 is attached as shown in FIGS.

The pressure circulating pump 6 is a pump such as a self-priming fugal pump, and is arranged along the wall surface 5 of the bathroom 1 and attached to the wall surface 5 with a mounting bracket 46. The discharge port of the pressure circulation pump 6 and the nozzle block 3 for shoulder contact are connected by a discharge hose 7. When the discharge hose 7 is connected to the shoulder block nozzle block 3, the end of the discharge hose 7 is connected to the connection port 47 of one of the left and right pedestals 18 with a cap nut 48, and the other pedestal The connection port 47 of 18 is closed by a blind lid 50. One end of a suction hose 8 is connected to the suction port of the pressurized circulation pump 6, the other end of the suction hose 8 is introduced into the bathtub 4, and a suction portion 51 is provided at the other end of the suction hose 8. It is. A control box 53 for driving the pressurized circulation pump 6 is arranged outside the bathroom 1, and the pressurized circulation pump 6 and the control box 53 are connected by a cable 54.

When the pressurizing and circulating pump 6 is driven by operating the operation switch 55 of the pressurizing and circulating pump 6 while bathing in the bathtub 4, hot water in the bathtub 4 is sucked from the suction hose 8 and pressurized and circulated. Shower water is sprayed from the shoulder-applying nozzle 2 via the pump 6, the discharge hose 7, and the shoulder-applying nozzle block 3, and the jet of shower water is applied to the shoulder to massage the shoulder. At this time, since the direction of the shoulder-applying nozzle 2 can be directed to an arbitrary direction, in the bathing posture, a strong stimulus can be given to the shoulder from above the shoulder from an optimal direction. Also, at this time, the head is held between the two shoulder-applying nozzles 2 while the bather is sitting in the bathtub 4.
The shoulder massage can be performed in a comfortable posture without discomfort.

[0012]

As described above, according to the present invention, the shoulder block nozzle block is housed in the case, and the concave portion having the curved surface corresponding to the curved surface of the human head is formed on the front side of the case. When a bather sits in a bathtub and puts his / her head between two shoulder-applying nozzles to spray shoulder water from the shoulder-applying nozzle to massage the shoulder, It can be placed on a curved part, can be massaged with the shower water by touching the head without discomfort, and it can be used for relaxing bathing by using the case of the nozzle block for shoulder rest as a pillow. And more concave
