Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shower device that moves an injection nozzle portion up and down and back and forth, and more specifically, it improves the appearance of the shower device and also improves the ability to move the injection nozzle portion up and down over a long period of time. This relates to technology that facilitates smooth operations.

[Prior Art] In recent years, 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.

As shown in Fig. 6a, this type of system switches the direction of the water flow sent into the hydraulic cylinder 5 by passing it through a directional control valve 24, so that it can continuously move up and down. It is something to do. That is, the injection nozzle part 1 is connected to the wire 8 connected to the piston 7 in the hydraulic cylinder 5.
A slider 9 is fixed to the slider 9, and the injection nozzle section 1 is attached to the slider 9 to drive it up and down.

[Problems to be Solved by the Invention] However, according to the above-described configuration, as shown in FIG. Because of this, there is a problem that the injection nozzle part 1 may get caught and be forcibly stopped, or children may get their hands or fingers caught. Also, since there are multiple injection nozzle parts 1, there is a problem that the injection nozzle part 1 may get caught and be forcibly stopped. If you do not operate with water pressure, there may be an imbalance in the injection condition.
It is necessary to adjust the balance between the left and right injection nozzle parts 1, and problems remain in terms of usability, water saving, and energy saving. On the other hand, as a means to solve the above-mentioned problems, a shower device S is provided in which a vertically elongated slit 4 is provided in the casing 3 and an injection nozzle portion 1 is provided so as to move up and down along this slit 4, as shown in FIG. has been done. In this case, blindfold belts 11 are attached to the upper and lower ends of the slider 9 to which the injection nozzle part 1 is attached to visually close the gap between the slits 1 to improve the appearance and to prevent fingers and hands from moving up and down. Although it has the advantage of ensuring safety by preventing it from getting caught, the surface of the blindfold belt 11 and the drive mechanism inside the slider 9 can become contaminated with dirt, mold, etc. due to long-term use, resulting in aesthetic and sanitary problems. The disadvantage was that there were problems above.

In addition, when attempting to vertically reciprocate the injection nozzle part 1 to the center of the casing 3, if the sliding parts do not rub together properly, noise may be generated during movement during long-term use, or rattling may occur due to wear. There was a problem.

The present invention was made in view of these problems, and its purpose is to allow the slider to move up and down reciprocally with a good appearance and safely, and to prevent dirt and dirt caused by shower water, etc. To provide a shower device that can prevent the growth of mold, can be smoothly reciprocated up and down for a long period of time, and can improve hygiene and durability.

A drive mechanism section 2, which is made up of a cylinder 5 for reciprocating the injection nozzle section 1, a wire 8, and various other members such as a reversing mechanism section 13, which will be described later, is covered with a casing 3 as shown in FIG. 1c. A long slit 4 is formed in the center of the casing 3. A guide rail 10 is vertically arranged inside the casing 3 along this slit 4. A slider 9 is slidably provided on the guide rail 10, and the slider 9 holds the injection nozzle part 1 facing the slit 4 shown in FIG. 1c.

However, as shown in Figure 1, the driving water is supplied to the four-way valve 6
After passing through, the water enters the upper pressurizing chamber 5a of the cylinder 5 and pushes down the piston 7, thereby distributing the water in the lower pressurizing chamber 5b of the cylinder 5 through the four-way valve 6. This downward movement of the piston 7 causes the injection nozzle portion 1 to rise via the wire 8 and slider 9. When the injection nozzle part 1 reaches the upper limit position, it kicks the height adjustment clamp 14 on the reversal mechanism part 13, pushes up the reversal rod 15 to which the height adjustment clamp 14 is integrally attached, and switches the four-way valve 6. . By switching the four-way valve 6,
The driving water passes through the flow path a, enters the lower pressurizing chamber 5b of the cylinder 5, pushes up the piston 7, lowers the injection nozzle part 1 via the wire 8 and slider 9, and the water in the upper pressurizing chamber 5a The water is drained through the four-way valve 6 through the flow path b. When the injection nozzle part 1 is lowered to the lower limit position, the lower height adjustment clamp 14 is kicked, and the reversing rod 1
5 is lowered, the four-way valve 6 is switched as shown in FIG. 1b, the initial state is returned, and the injection nozzle portion 1 is raised again. From now on, this kind of operation will be repeated.

As shown in Figure 5b, in its horizontal cross-sectional state,
