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 pressure circulating 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]

However, in the above method, the suction hose is simply introduced into the bathtub, and the bath water is simply sucked in from the opening at the tip of the suction hose. The end of the hose may be easily blocked by hand. In addition, there is a problem that the shoulder-use nozzle or the like may be clogged because the dirt in the bath water is directly sucked from the suction hose. Further, when the operation of the pressurized circulation pump ends, the bath water in the suction hose returns to the bathtub. For this reason, the next operation requires 5 to 10 seconds to draw the bath water into the suction hose, and the sound at this time is noisy. Furthermore, there is a problem that the suction hose is not fixed to the bath tub, which hinders bathing, and that even if the suction hose is not installed in the bath tub, the bath lid is difficult to use after use. .

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and a first object of the present invention is to prevent the suction port from being easily clogged and to discharge the fuel from the shoulder-applying nozzle. Another object of the present invention is to provide a shower device for a bathtub shoulder which is always stable, and a suction filter for a bathtub which can prevent a decrease in performance due to clogging of a nozzle for a shoulder bath by a suction filter. A third object of the present invention is to provide a shower device for use in a bath, in which the bath water in the suction hose does not flow back into the bathtub, and the waiting time until shower water spouts from the shoulder pad nozzle. A fourth object of the present invention is to provide a shower device for a shoulder tub in which a suction hose is eliminated, and a suction hose which can be easily fixed in the bath tub and is not used. There to provide a shoulder rest for a shower apparatus of the tub that can be stored so that it does not get in the way.

[0005]
