Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a shower device that moves an injection nozzle part up and down and back and forth, and more specifically relates to a technology that attempts to smoothly raise and lower the injection nozzle part over a long period of time. It is something.

[Prior Art] Recently, shower devices have been recognized as having features such as ease of preparation for bathing, water saving, and energy saving, and have become established as a convenient means of bathing. On the other hand, as social needs for health promotion have increased, attention has been focused on the water pressure stimulation and thermal stimulation effects of shower jet pressure. 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, the key is to make the stimulating effects of the jet water last as long as possible by varying the temperature and water pressure of the jet water. To this end, attempts have been made to move the shower head itself up and down and back and forth in order to avoid spraying water from hitting the same position on the body as much as possible, and conventionally a drive system using a hydraulic cylinder has been adopted.

This system, as shown in Figure 6,
Switching the direction of the water flow sent into the hydraulic cylinder 7 by passing it through the directional switching valve 12,
This is intended to cause continuous up and down reciprocation. That is, the ejecting nozzle part 1 is driven up and down by fixing the elevating body 3 to the wire 9 connected to the piston 8 in the hydraulic cylinder 7, and attaching the ejecting nozzle part 1 to the elevating body 3.

[Problem to be solved by the invention] According to such a configuration, as shown in FIG. is provided and the water supply hose 5 is connected to this side, so an unbalanced load is applied to the elevating body 3 that slides relative to the vertical guide 2 such as a rail, and as a result, the elevating body 3 and the vertical guide 2 are There was a problem in that uneven wear occurred and rattling occurred when the elevating body 3 moved up and down. In addition, in the past, a large amount of space was required to store the flexible water supply hose 5 that supplies cleaning water to the injection nozzle section 1, and the design was not cohesive and unbalanced. If the water supply hose 5 is exposed from the case and is pulled by a child or the like, there is a problem that the elevating body 3 having the injection nozzle portion 1 may be difficult to ascend and descend, and the elevating drive portion thereof may be damaged. .

The present invention was developed in view of these problems, and its purpose is to avoid the application of unbalanced loads to the elevating object and to allow the elevating object to move up and down smoothly over a long period of time. To improve the reliability of the device, and to store the water supply hose compactly, to suppress or reduce the exposure of the water supply hose, and to prevent the water supply hose from being pulled by children or getting caught on other objects. We have developed a shower device that avoids damage to the elevating drive part of the injection nozzle, increases the reliability of the device in this respect, and also reduces the size of the shower device and minimizes the installation space. It is about providing.

[Means for Solving the Problems] In the shower device of the present invention, an ejection nozzle portion 1 is disposed at one end in the left-right direction of an elevating body 3 that is held so as to be able to move vertically and reciprocally with respect to a vertical guide 2, and the spray nozzle portion 1 is disposed at one end in the left-right direction. A water supply port 4 for supplying cleaning water to the injection nozzle portion 1 is formed on the side, and a water supply hose 5 is connected to the water supply port 4.

In addition, the original water supply port 6 to which the base end of the water supply hose 5 is connected, the injection nozzle part 1, and the water supply port 4 are arranged in this order in the left-right direction, and the main water supply port 6 and the water supply port 4 are connected to a flexible water supply hose. It is characterized in that it is connected at 5.

[Function] In this way, the injection nozzle part 1 is arranged at one end in the left-right direction of the elevating body 3 which is held so as to be able to move vertically and reciprocally with respect to the vertical guide 2, and the washing water is supplied to the injection nozzle part 1 at the other end. By forming a water supply port 4 that supplies water and connecting a water supply hose 5 to the water supply port 4,
This avoids greatly unbalancing the load on the left and right sides of the elevating body 3, balances the load on the left and right, suppresses the unbalanced load on the elevating body 3, and prevents the imbalance between the elevating body 3 and the vertical guide 2 due to the unbalanced load. This avoids wear and allows the elevating body 3 to be smoothly raised and lowered over a long period of time with simple improvements, thereby increasing the reliability of the device.

In addition, the original water supply port 6 to which the base end of the water supply hose 5 is connected, the injection nozzle part 1, and the water supply port 4 are arranged in this order in the left-right direction, and the main water supply port 6 and the water supply port 4 are connected to a flexible water supply hose. 5, the flexible water supply hose 5 forms a substantially U-shape and straddles the injection nozzle part 1, allowing the water supply hose 5 to be housed compactly and to prevent the water supply hose 5 from being exposed from the outer shell case. Water supply hose 5 that can be suppressed and reduced
This prevents the water supply hose 5 from being pulled by children or getting caught on other objects, and avoids damage to the lifting drive unit caused by the water supply hose 5 being pulled unexpectedly, increasing the reliability of the device in this respect as well. , and by housing the water supply hose 5 compactly, the shower device is made smaller and its design is improved.

[Examples] Examples of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 2, the shower device S has a piston 8 arranged in a vertical hydraulic cylinder 7 so as to be vertically movable up and down, and a wire 9 wound around wheels 11, 11 is tightly tied to the piston 8. A slider 3a is connected to the wire 9 as the elevating body 3, and the injection nozzle portion 1 is fixed to the slider 3a.

On the other hand, the pressurized water for driving the injection nozzle part 1 up and down is supplied from port A of the four-way valve 12 as a directional switching valve, through the fan hole 12a of the four-way valve 12, and via port B to the upper pressurizing chamber 13 of the cylinder 7. After the piston 8 is lowered, the port C of the four-way valve 12 is
Return to port D through the fan hole 12b of the four-way valve 12.
It is designed to drain more water. In such a flow of pressurized water, the slider 3a rises, causing the injection nozzle portion 1 to rise. and injection nozzle part 1
rises and contacts the height adjuster 14, actuating the reversing transmission mechanism 15, switching the four-way valve 12, and the pressurized water from port A passes through the fan hole 12a whose position has been changed due to switching and flows to port C. The water is sent under pressure to the lower pressurizing chamber 16 of the hydraulic cylinder 7 via , and after raising the piston 8, returns to port B, and is drained from port D through the fan hole 12b whose position has been changed. . As the piston 8 rises, the slider 3a descends, and the injection nozzle portion 1 also descends. Repeat this operation below.

The reversing transmission mechanism 15 includes a slide rod 17 that is held so as to be slidable, a height adjuster 14 that is attached to the slide rod 17 so that its position can be changed, and a rack gear 1 that is integrally attached to the slide rod 17.

It is mainly composed of a connecting pin 23 to be connected. When the injection nozzle part 1 rises and comes into contact with the upper height adjuster 14, the slide rod 17 fixed thereto is lifted up, the reversing gear 19 meshed with the rack gear 18 is rotated, and the reversing gear is rotated. While compressing the spring 21, the reversing rocking rod 22 is retired to the rotation shaft 20 side and swinging to the right in FIG. Due to the elastic restoring force of 21, the reversing swing rod 22 protrudes beyond the rotating shaft 20, reversing the reversing gear 19, switching the four-way valve 12 in reverse, and opening the fan hole 12.
The positions of ports a and 12b relative to ports A, B, C, and D are changed so that the pressure water flow path can be switched. In this way, as a lifting force,
Although water pressure is used in this embodiment, electric power such as motor drive or other means may be used.
