[Background technology]

BACKGROUND ART Shower devices have recently been recognized as a convenient means of bathing, as they are easy to prepare for bathing, save water, and save energy. On the other hand, as social needs for health promotion have increased, attention has been focused on the skin irritation and thermal stimulation effects caused by the spray pressure of showers. In other words, a stimulating hot bath increases blood flow, activates various functions such as the circulatory system, respiratory system, and autonomic nervous system, and is effective for relaxing the mind and body, recovering from fatigue, and beautifying. has been recognized. In order to increase these effects, it is necessary to take measures such as changing the temperature and water pressure of the jet water to maintain the stimulating effect of the jet water as long as possible. To this end, attempts have been made to move the shower head itself up and down and back and forth in order to spray hot water over a wide area of the body with as little amount as possible, and as a conventional example, a driving method using a hydraulic cylinder has been adopted. This system, as shown in Figure 9,
The direction of the water flow sent into the cylinder 5 is reversed by passing it through the four-way valve 6, so that it can continuously move up and down. That is, in the shower nozzle 1, a slider 9 is fixed to a wire 8 connected to a piston 7 in a cylinder 5, and the shower nozzle 1 is attached to the slider 9 and driven up and down. In the conventional example, while adopting the above-mentioned drive system, as shown in FIG. In order to attach the abutment 41 to the slide rod 16 provided inside the outer shell cover 23 so that the position can be changed freely, the first
As shown in FIG. 3, the slide guide 43 is slidably inserted into the slide rod 16, the set screw 42 screwed into the slide guide 43 is pressed against the brake piece 44, and the slide rod 16 is inserted between the slide guide 43 and the brake piece 44. When changing the position of the abutment 41, loosen the set screw 42, slide the slide guide 43 to the desired position relative to the slide rod 16, and then tighten the set screw 42. As described above, two operations of loosening and tightening the set screw 42 are required, and the operation takes time. Moreover, since it is a screw type, if the tightening force is insufficient, the connection to the slide rod 16 will be broken, making it impossible to move the slide rod 16 and making it impossible to reverse the shower nozzle 1, which tends to cause reliability problems. If the set screw 42 is tightened too strongly, it is difficult for children or the elderly to perform the release operation, and there are problems such as damage to the screw hole into which the set screw 42 is screwed.

[Purpose of invention]

The present invention was developed in view of these problems, and its purpose is to change the inversion position of the shower nozzle upside down.
To provide a shower device that improves operability, prevents the set state from being canceled unexpectedly, improves the reliability of changing the reversing position, and allows anyone to perform such operations easily and quickly. It's about doing.

[Disclosure of invention]

The shower device of the present invention changes the vertically inverted position of the shower nozzle 1, which is reciprocated up and down, based on the vertical movement of the slide rod 16 connected to the abutment 41 as it comes into contact with the upper and lower abutments 41, 41. This shower device is equipped with an inverting device 14 that detects the movement of the shower nozzle 1 and inverts the movement of the shower nozzle 1 up and down based on the detection result, with the hit 41 being a pivot point P.

The reliability of the operation during position changes is increased, and since the connection force of the contact 41 to the slide rod 16 is determined by the spring 45, the connection force does not become stronger than that, and the connection can be disconnected with less force. Even a weak elderly person can perform the operation, and anyone can perform the operation easily and quickly. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. As shown in FIG. 1, the shower device S has a piston 7 arranged in a vertical cylinder 5 so as to be vertically movable up and down, and a wire 8 wound around wheels 11, 11 is tightly tied to the piston 7. A slider 9 is connected to the wire 8, and a shower nozzle 1 is fixed to the slider 9. On the other hand, the pressurized water for driving the shower nozzle 1 up and down is sent from port A of the four-way valve 6 as a switching valve to the upper pressurizing chamber 12 of the cylinder 5 via the fan hole 6a of the four-way valve 6 and through port B. After the piston 7 is lowered, it returns to the port C of the four-way valve 6, passes through the fan hole 6b of the four-way valve 6, and drains from the port D. In such a flow of pressurized water, the slider 9 descends and the shower nozzle 1 is raised. Then, the shower nozzle 1 rises and contacts the contact 41, actuating the reversing device 14, switching the four-way valve 6, and the pressurized water from port A passes through the fan hole 6a whose position has been changed due to switching, and flows to port C.
