TECHNICAL FIELD The present invention relates to a shower device used in a bathroom or the like,
More specifically, the present invention relates to a shower device in which a shower nozzle is reciprocally moved, and more specifically, it relates to a technique for improving appearance and safety, and improving cost and durability.

[Prior Art] Recently, the shower device has been recognized as a simple bathing means because it is easy to prepare for bathing, saves water, and saves energy. On the other hand, social needs for health promotion have increased, and attention has been paid to the effects of skin irritation and thermal irritation by the spray pressure of the shower. In other words, it has been confirmed that it is effective for relaxing the mind and body, recovering from fatigue, and beauty by increasing the blood flow by stimulating a hot bath and activating various functions such as the circulatory system, respiratory system and autonomic nervous system. Has been.

In order to increase these effects, it is necessary to change the water temperature and water pressure of the jet water so that the stimulating effect of the jet water is maintained as long as possible.

For that purpose, an attempt has been made to move the shower head itself up and down so that the water can be sprayed onto the body in a wide range with a small amount of hot water. As a conventional example, a drive system using a hydraulic cylinder has been adopted.

In this system, as shown in FIG. 5, the direction of the water flow sent into the hydraulic cylinder 5 is switched by passing through the direction switching valve 6, and the vertical reciprocating movement is continuously performed. is there. That is, the shower nozzle 1
The slider 9 is fixed to the wire 8 connected to the piston 7 in the hydraulic cylinder 5, and the shower nozzle 1 is attached to the slider 9 to drive the slider 9 up and down.

While adopting the drive system as described above, in the conventional example, as shown in FIG. 6, the shower nozzle 1 was disposed so as to project from the casing 3 on both sides of the drive mechanism portion for driving the shower nozzle 1. , I had the following problems.

a. Since the shower nozzle 1 and the shower hose protrude from the casing 3 and are exposed, there is a safety problem that an infant or the like may be caught with a finger or the like, and it is impossible against the hydraulic drive force as an example of the drive mode. There is a risk of mischievous act such as stopping or moving it, which damages the drive mechanism or shortens its durability.

b. Since the shower nozzle 1 projects to the outside, the appearance is impaired, and the cost is increased for ensuring the strength of the casing 3, the shower nozzle 1 and the supporting portion thereof, and for finishing the makeup.

On the other hand, in the conventional example, since the shower nozzles 1 are arranged on both sides of the drive mechanism unit, the amount of water to be sprayed is required to be about 15 to 16 in order to secure a shower spray pressure suitable for a massage shower. No.) has insufficient heating capacity in the winter, and a large-scale water heater with high cost (capacity 22 or higher) is required. In addition, the water supply and hot water supply pressure is 2.5 to 3.
If it is less than 0 kg / cm ² , there is a problem that the amount of water jet is reduced and the stimulation feeling as a massage shower cannot be obtained.
In order to solve this, a hot water supply pressure pump is connected, which causes a problem of high construction cost.

[Problems to be Solved by the Invention] The present invention has been made in view of such problems,
It is an object of the present invention to provide a shower device in which the reciprocating movement of the shower nozzle can be safely performed with good appearance, and the cost and durability can be improved.

[Means for Solving the Problem] A shower device according to the present invention is a shower device that reciprocates a shower nozzle 1, and is long in a substantially central portion of a casing 3 that covers a drive mechanism 2 that reciprocally drives the shower nozzle 1. A slit 4 is formed, a guide 10 is arranged inside the casing 3 along the slit 4, and a slider 9 which is reciprocally driven by a drive mechanism unit 2 is slidably movable on the guide 10 so as to face the slit 4. The shower nozzle 1 is held by a slider 9, and a long blind belt 11 is attached to the shower nozzle 1 which is movable along the slit 4 so as to cover the slit 4 even when the shower nozzle 1 is moved. It is characterized by that.

Further, it is characterized in that the drainage from the drive mechanism section 2 for reciprocating the shower nozzle 1 is scattered on the blind belt 11 to wash the internal structure section of the casing 3.

[Operation] As described above, the long slit 4 is formed in the substantially central portion of the casing 3 that covers the drive mechanism portion 2 that reciprocally drives the shower nozzle 1, and the guide 10 is disposed inside the casing 3 along the slit 4. A slider 9 that is reciprocally driven by the drive mechanism unit 2 is provided on the guide 10 so as to be slidably movable, and the slit 4
By holding the shower nozzle 1 facing the above with the slider 9, the appearance is enhanced as compared with the conventional configuration in which the shower nozzle 1 is provided outside the casing 3, and the shower nozzle 1 protrudes to the outside. It can be stored in the casing 3 without the need to touch the shower nozzle 1 and accidentally pinch a finger, improve safety and durability, and by disposing the shower nozzle 1 inside the casing 3, This does not require costly finishing of the appearance or the like, and is advantageous in terms of cost.

Further, blind belts 11 are attached to both ends of the shower nozzle 1 that moves along the slit 4, and the shower nozzle 1 is moved along the long slit 4 by covering the slit 4 even when the shower nozzle 1 moves. On the other hand, the slit 4 portion other than the shower nozzle 1 can be hidden by the blindfold belt 11, which further enhances the appearance.

Further, by draining the drainage from the drive mechanism 2 that drives the shower nozzle 1 back and forth to the blindfold belt 11 to wash the internal structure of the casing 3, the drainage from the drive mechanism 2 can be effectively used. The inner structure is cleaned to maintain the inside clean.

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

As shown in FIG. 1, the shower device has a vertical hydraulic cylinder 5 in which a piston 7 is vertically movable, and a wire 8 wound around the rolling wheels 12 and 12 is connected to the piston 7.
The slider 9 is connected to the wire 8, and the shower nozzle 1 is fixed to the slider 9. A drive mechanism section 2 composed of various members such as a reversing mechanism section 13 described later in addition to a cylinder 5 and a wire 8 for reciprocally driving the shower nozzle 1 is covered with a casing 3, and a central portion of the casing 3 is covered with the drive mechanism section 2. A long slit 4 is formed. A guide 10 is vertically arranged inside the casing 3 along the slit 4. A slider 9 is slidably provided on the guide 10, and the shower nozzle 1 facing the slit 4 is held by the slider 9.

Then, as shown in FIG. 1, the driving water passes through the four-way valve 6 and then enters the upper pressurizing chamber 5a of the cylinder 5 and pushes down the piston 7 to make the water in the lower pressurizing chamber 5b of the cylinder 5 four-way. It drains through valve 6. The descending movement of the piston 7 raises the shower nozzle 1 through the wire 8 and the slider 9. When the shower nozzle 1 reaches the upper limit position, the height adjusting tool 14 above the reversing mechanism 13 is kicked, and the reversing rod 15 to which the height adjusting tool 14 is integrally attached is pushed up to switch the four-way valve 6. By switching the four-way valve 6, the driving water passes through the flow path a and enters the lower pressurizing chamber 5b of the cylinder 5, pushes up the piston 7, lowers the shower nozzle 1 through the wire 8 and the slider 9, and then the upper heating Water in the pressure chamber 5a passes through the flow path b
The water is drained through the four-way valve 6. Then, when the shower nozzle 1 is lowered to the lower limit position, the lower height adjusting tool 14 is kicked, the reversing rod 15 is lowered, and the four-way valve 6
, The shower nozzle 1 is raised again. After that, such an operation is repeated.

As shown in FIG. 2, the shower nozzle 1 is located in the center of the casing 3 in the horizontal cross-sectional state, the guides 10 are arranged on both sides of the shower nozzle 1, and the guide 10 is integrated with the shower nozzle 1. A slider 9 is slidably inserted. The wire 8 is fastened to the slider 9. As shown in FIG. 4, the blindfold belts 11 are connected to the upper and lower sides of the shower nozzle 1 and wound around the upper and lower pulleys 17 attached to the fixed base 16 integrated with the guide 10 to form an endless shape. The blindfold belt 11 rotates as the shower nozzle 1 moves up and down, and the blindfold belt 11 constantly covers the slit 4 of the casing 3 regardless of the movement of the shower nozzle 1.

The drainage section 18 of the four-way valve 6 is arranged further above the pulley 17 on which the blindfold belt 11 is wound, and the drainage from the four-way valve 6 scatters on the blindfold belt 11,
The inside structure of the casing 3 can be washed with the drainage adhering to the blindfold belt 11 while preventing the stains from becoming dirty.

The four-way valve 6 and the reversing mechanism unit 13 include a four-way valve main body 19, a four-way valve lid 20, a valve body 21, a valve shaft 22, and a pinion gear 23 which is a reversing gear integrated with the valve shaft 22, and the pinion gear 2.
The guide gear 1 is engaged with a rack gear 25 and an operating shaft 24 which are engaged with the reversing rod 15 and which are pushed up by the reversing rod 15 and are movably held.
The holding shaft 26 fixedly attached to 0 and the operating shaft 24 are composed of a reversing spring 27, etc., which is inserted between the lower end of the rack gear 25 and the holding shaft 26. The reversing rod 15 is moved upward by contacting the adjusting tool 14, the pinion gear 23 is rotated through the rack gear 25, the valve shaft 22 is rotated, and the valve element 21 is switched. When contacting the height adjuster 14, the reversing rod 15 is lowered, the pinion gear 23 is rotated through the rack gear 25, and the valve element 22 is switched.

Water supply to the shower nozzle 1 is performed by a flexible water supply hose 28, which is contained in the casing 3 in the embodiment.
It is also possible to use a configuration in which 8 is not incorporated.

With such a structure, the shower nozzle 1 moves up and down in the guide 10 via the slider 9, so that the up-and-down operation can be smoothly performed without rattling. And since the blindfold belt 11 is interlocked with the shower nozzle 1 in the slit 4 of the casing 3, the internal structure is not visible and the design is improved, and at the same time, it is not possible to insert a hand inside, and it is safe, It is difficult for shower water to enter the inside, and it also prevents dirt inside.

Further, since the four-way valve block 30 is located above the shower nozzle 1 and is fixed to the guide 10, the height adjusting tool 1
4. The reversal signal from the reversing rod 15 is accurately transmitted to the four-way valve block 30 and the reversal of the reciprocating motion becomes smooth.

Further, since the drainage portion 18 of the four-way valve 6 is above the upper pulley 17 around which the blindfold belt 11 is wound, drainage scatters on the blindfold belt 11 and flows down through the blindfold belt 11, so that the shower nozzle 1 and the slider are provided. 9. The drainage is applied to the guide 10 to remove the dirt caused by the shower water being scattered, and at the same time, the dirt is prevented from adhering.

[Effects of the Invention] In summary, according to the present invention, a long slit is formed in a substantially central portion of a casing that covers a drive mechanism portion that reciprocally drives a shower nozzle, a guide is arranged inside the casing along the slit, and the guide is driven. Since the slider that is reciprocally driven by the mechanism is slidably movable and the shower nozzle facing the slit is held by the slider, compared to the conventional configuration where the shower nozzle is provided outside the casing. The shower nozzle can be stored inside the casing without protruding to the outside, you can avoid accidentally pinching your fingers by touching the shower nozzle, safety is also improved, and the shower nozzle is casing. By arranging it inside, there is no need to finish it in appearance, etc., and it is also advantageous in terms of cost. In addition, since it is covered entirely with the casing, there is an advantage that each part can be protected and durability can be improved.

In addition, blind belts are attached to both ends of the shower nozzle that moves along the slit so that the slit is covered even when the shower nozzle moves, so that the slit portion other than the shower nozzle is moved while moving the shower nozzle along the long slit. Can be hidden by a blindfold belt to further enhance the external appearance and prevent shower water from entering through the slits.

Also, by draining the drainage from the drive mechanism that reciprocally drives the shower nozzle to the blindfold belt to wash the internal structure of the casing, the drainage from the drive is effectively used. There is an advantage that the inside can be maintained clean by carrying out the cleaning.
