If an alternate operation type switch is used for the operation unit 14 for turning on / off the rotation of the motor 11, the shower head 1 can be held on the shower hook 6 while maintaining the pressurized state of hot and cold water. It is preferable to improve.

  Moreover, as shown in FIG. 3, the charging circuit 16 for charging the rechargeable battery unit 10 of the rotary pressurizing unit 9a uses an electric circuit built in the shower hook 6 as a charging device. The battery units 10 are electrically connected by a transformer 17. In other words, the charging circuit 16 includes a primary circuit 16 a that includes the primary coil 20 of the transformer 17 and is connected to an external power source 25 such as a commercial power source via an electrical wiring and the like, and a secondary coil 21 that is electrically connected to the charging battery unit 10. And the secondary circuit 16b connected through the like.

The primary side core 20a has a C-shape in plan view along the inner peripheral surface which is the holding surface of the hook portion 7, so that the inside of the hook portion 7 which is a dead space of the shower hook 6 is the primary coil. The arrangement space becomes 20, and the shower hook 6 can be made more compact. Furthermore, by providing the protrusion 15 having the rotary pressurizing part 9a and the secondary coil 21 below the gripping part 2a, it is possible to suppress the shape change such as an increase in the size of the gripping part 2a and make it compact. Therefore, when attaching / detaching the shower head 1 from / from the shower hook 6, the rotary pressurizing unit 9 a and the charging circuit 16 do not disturb the gripping of the gripping unit 2 a by the user, and are easy to use.

  The shower device of the present invention may be used as an auxiliary pump for further pressurizing hot water pressurized by a pump provided with a hot water pressurizing means 9 with a hot water pressurizing means 9 attached to a hot water storage tank provided with a shower pump. . In other words, if the water pressure at the time of shower use cannot be sufficiently applied to the hot water by the pump of the hot water storage tank due to the convenience of the installation position or by changing the discharge port 4 of the shower head 1 to a large-diameter having a large spray area, The hot water is further pressurized by the pressurizing means 9 so that the shower can be used with a comfortable water pressure.

  Furthermore, even when hot water with sufficient water pressure can be discharged from the shower outlet by the existing shower device, the water pressure higher than the existing water pressure by the hot water storage tank pump, etc. can be set to the user by installing the shower device of the present invention. It is good also as what gives the massage effect by a shower, or what the user can adjust the water pressure of the hot water discharged from the discharge port 4 of the shower head 1 with the hot water pressurization means 9 by the operation part 14.

  Of course, the hot water pressurizing means 9 may be an impeller, a propeller, or the like that pressurizes and flows hot water with a member separate from the rotor 11b. Moreover, even if it is a washstand without a shower device, the curan can be replaced with a shower hose 24 or a shower that can branch hot and cold water, and the present invention can be replaced to replace the washstand main body. Even if a new pump is not installed in the lower storage part of the wash basin, it can be replaced with a wash basin that can use a comfortable water pressure shower.
