DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a shower device for a home bathroom, shower room, or the like.

Construction of the conventional example and its problems The conventional method of showering the body in multiple directions and over multiple areas is as shown in Figure 1, in which a shower head D is installed on each wall in a space surrounded by walls A, B, and C. There are examples where showerheads are installed in large numbers in multiple directions and in multiple stages, but the large number of showerheads results in an excessive amount of water passing through, which is uneconomical as it consumes a large amount of heating energy and water, so there are few practical examples of this. For this reason, in many cases, a single hand-carried shower head is used to inject spray onto various parts of the body, but this is accompanied by some inconvenience compared to the previous example, such as one hand being tied up to hold the shower head. It has some problems.

Purpose of the Invention In order to improve the problems of the conventional example, the present invention eliminates the inconvenience of manual transportation, saves the amount of water sprayed, and automatically sprays a shower over a wide range of parts of the body. The purpose is to

Structure of the Invention The present invention has a structure in which a shower head is fixed to a wire stretched between two pulleys, and one of the pulleys is driven by an electric motor that reverses the direction within the distance between the two pulleys to perform shower injection.

Description of examples Embodiments of the present invention are shown in FIGS. 2 and 3.

In Fig. 2, for case 1, electric motor 2
and a bearing 3, and a pulley 4 is fixed to each of the rotating shaft of the electric motor 2 and the rotating shaft provided in the bearing 3,
A wire 5 is stretched between both pulleys 4, and the end face of the shower head 6 is fixed. The shower head 6 is connected to a water supply valve 8 through a hose 7, and a flow rate control section 9 is provided on the water supply valve 8. The water supply valve 8 receives water from the outside through a water supply port 8'. The rotational speed of the reversing drive of the electric motor 2 can be arbitrarily controlled by a separately provided electronic controller.

The above configuration provides the following effects. By driving the electric motor 2 in reverse, the shower head 6
The electric motor 2 can be reciprocated between the two fixed pulleys 4 depending on the rotational speed of the reversing drive, or the electric motor 2 can be stopped at a desired position between the pulleys 4 of the shower head 6 and the shower can be started at a fixed position. The system adds the convenience of being able to select the position compared to the conventional fixed shower spray method, and at the same time provides unprecedented reciprocating motion to provide a wide range of cleansing effects on the body through shower spray without the need for manual transport. It can be used comfortably without any need.

As another embodiment, shown in FIG. 3, separate shower heads 6 are fixed to both sides of the wire 5 with the pulley 4 interposed therebetween, and the shower heads 6 move in opposite directions.

Next, a method of controlling the rotation of the electric motor 2 and a method of controlling the amount of water supplied to the shower head 6 will be described.

As shown in FIG. 4, the operation of the electric motor 2 is controlled by an inversion control circuit 13 and a speed control circuit 14 connected to a power supply circuit 16 via an operation switch 17. Inversion control circuit 13
As shown in FIG. 2, the electric motor 2 rotates when the shower head 6 reaches each switch based on signals from an upper reversing switch 11 and a lower reversing switch 12, which are movably disposed on the flow line of the shower head 6. After stopping once, the shower head 6 is configured to start rotating in the opposite direction to the conventional one, and the shower head 6 repeats reciprocating motion between the upper reversing switch 11 and the lower reversing switch 12.

The speed control circuit 14 functions to change the moving speed of the shower head 6 by controlling the rotational speed of the electric motor 2 at a speed set continuously or stepwise by a speed regulator 15.

The power supply circuit 16 supplies the optimum power for operating the inversion control circuit 13, speed control circuit 14, and electric motor 2.

The operation switch 17 is used to start and stop the electric motor 2.
This can be done by turning on and off. The shower head 6 stops at any position when the operating switch 17 is turned OFF, but when the operating switch 17 is turned OFF again.
When turned ON, whether the shower head 6 is activated up or down can be selectively set by the configuration of the reversal control circuit 13.

FIG. 5 shows a control configuration of the electric valve 21 that controls the amount of water supplied to the shower head 6. As shown in FIG.

By adjusting the water supply switch 20, the valve control circuit 1
The electric valve 21 controls the amount of water supplied to the shower head 6 according to a command from the shower head 9. The power supply circuit 18 supplies the optimum power to operate the valve control circuit 19 and the electric valve 21.

Effects of the Invention Based on the effects of the embodiments, the present invention has the following effects.

(1) With one or two shower heads, it is possible to spray a wide range of water onto various parts of the body while saving water and reducing heat consumption.

(2) Furthermore, unlike the conventional hand-carrying method, since the device automatically carries out the process, inconveniences such as being able to shower while using both hands freely are eliminated, and the comfort of the shower is improved.

(3) The simple structure of an electric motor and pulley provides an unprecedentedly advanced shower injection function.
