Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a shower device used in bathrooms, etc., and more specifically, to a shower device in which the shower nozzle can be moved back and forth in the vertical direction. It also relates to technology that is intended to be advantageous.

[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 make the shower head itself move back and forth up and down 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 4,
The direction of the water flow sent into the cylinder 5 is reversed by passing it through a 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, the shower nozzle 1 is arranged so as to protrude from the overall cover 23 on both sides of the drive mechanism section for driving the shower nozzle 1, as shown in the external appearance in Fig. 5. As a result, the following problems arose. a Since the shower nozzle 1 protrudes from the overall cover 23 and is exposed, there is a safety problem such as children's fingers getting caught, and it is impossible to force it against the water pressure driving force as an example of the drive form. There is a risk of tampering with stopping or moving the drive mechanism, which may damage the drive mechanism or shorten its durability. b Since the shower nozzle 1 protrudes outside,
They lack a smart design, and they tend to attract dirt, which requires maintenance such as cleaning them. c. Since the shower nozzle 1 is exposed to the outside, the cost increases in order to maintain sufficient strength in the body of the shower nozzle 1, its supporting portion, etc., and to apply a decorative finish. On the other hand, in order to detect the vertically inverted position of the shower nozzle 1 by contacting it with the abutment 13a, and to invert the movement of the shower nozzle 1 up and down based on this detection result, the abutment 13a is as shown in FIG. It is provided in a slit 33 dedicated to the contact 13a formed on the side surface of the overall cover 23, and therefore,
The cover shape becomes asymmetrical, the molding cost increases, and the contact 13a of the height adjuster 13
It was difficult to see the position from the front, and there were also problems with operability.

[Purpose of invention]

The present invention was developed in view of the above-mentioned technical background, and its purpose is to provide a shower device that has improved safety, durability, and appearance, and is also advantageous in terms of cost and operability. There is a particular thing.

The shower device of the present invention is a shower device equipped with a shower nozzle 1 that is reciprocally moved up and down, and the shower nozzle 1 is disposed inside a front cover 3 that covers a drive mechanism section 10 that drives the shower nozzle 1. The injection outlet 2 is arranged in a slit 4 formed in the front cover 3, and the vertically inverted position of the shower nozzle 1 is detected by contacting the abutment 13a, and based on this detection result, the movement of the shower nozzle 1 is controlled vertically. Reversible shower nozzle 1
The present invention is characterized in that a height adjuster 13 is provided, and a stop 13a is disposed within the slit 4. With this structure, the object of the present invention is achieved. That is, the shower nozzle 1 is disposed inside the front cover 3 that covers the drive mechanism section 10 that drives the shower nozzle 1, and the shower nozzle 1 is
The shower nozzle 1 is safe because it does not protrude and be exposed, there is no risk of fingers being caught, and the shower nozzle 1 cannot be forcibly stopped or moved against the driving force, and the drive mechanism part Since the shower nozzle 1 is not exposed and the shower nozzle 1 is not exposed, the design can be enhanced, the degree of freedom can be increased, and the appearance can be improved. Since the shower nozzle 1 is not exposed, there is no need to increase the strength of its body and supporting parts, and there is no need to improve the appearance, which is advantageous in terms of cost. By providing it in the same slit 4 as the shower nozzle 1, there is no need to provide a slit 33 dedicated to the hit 13a, which is advantageous in terms of cost, and the position of the hit 13a is easy to see, making it easier to operate. But it was designed to be advantageous. 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 is of a vertical type, or has a piston 7 arranged in a cylinder 5 so as to be vertically movable, 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 pressure water, the slider 9 rises, causing the shower nozzle 1 to rise. Then, the shower nozzle 1 rises and comes into contact with the height adjuster 13, activating the reversing mechanism 14, switching the four-way valve 6, and allowing the pressure water from port A to flow through the fan hole 6a whose position has been changed due to switching. lower pressure chamber 1 of cylinder 5 via port C.
5, and after raising the piston 7, it returns to port B, and is drained from port D through the fan hole 6b whose position has been changed. Then, the slider 9 descends together with the piston 7, and the shower nozzle 1 also descends. Repeat this operation below. The reversing mechanism 14 meshes with a slide rod 6 that is held so as to be slidable, a height adjuster 13 that is attached to the slide rod 16 so that its position can be changed, a rack gear 17 that is integrally attached to the slide rod 16, and a rack gear 17. A partial gear 18 is also connected to the four-way valve 6, and a reversing swing pin 20 is inserted into the rotating shaft 19 so as to be able to protrude and retract and is biased to project against the rotating shaft 19 by passing through a coil spring 21. The reversing swing pin 20 is connected to the partial gear so that when the reversing swing pin 20 crosses the dead line connecting the centers of the rotating shaft 19 and the partial gear 18, the reversing swing pin 20 is reversed by the elastic restoring force of the compressed coil spring 21. 18
It is mainly composed of a connecting pin 22 that is connected to the connecting pin 22. When the shower nozzle 1 rises and contacts the upper height adjuster 13, the slide rod 16 fixed thereto is lifted up and the rack gear 1

is retired to the rotating shaft 19 side and swung to the right in FIG. The partial gear 18 that protrudes beyond the moving shaft 19 is reversed, the four-way valve 6 is reversely switched, and the ports A of the fan holes 6a, 6b are opened.
The positions relative to B, C, and D are changed so that the pressure water flow path can be switched. Although pressure water is used to drive the shower nozzle 1, electric drive such as motor drive may be used, and there is no particular limitation. Overall cover 23 that covers the drive mechanism section 10 described above
Of these, vertically long slits 4, 4 are formed in the front cover 3, and the injection outlet 2 of the shower nozzle 1 is located within the slit 4. In this way, the shower nozzle 1 is placed inside the front cover 3 that covers the drive mechanism section 10 that drives the shower nozzle 1, so that the shower nozzle 1 does not protrude and be exposed, and there is no possibility of fingers being pinched. It is safe, and the shower nozzle 1 cannot be forcibly stopped or moved against the driving force, and the drive mechanism 10 is not damaged or the durability is impaired. Without exposing it, you can enhance the design and increase the degree of freedom.
The appearance can be improved, and the shower nozzle 1 is less likely to get dirty, and since the shower nozzle 1 is not exposed, there is no need to increase the strength of its body and supporting parts, and there is no need to improve the appearance, reducing costs. It can also be advantageous in terms of aspects. FIG. 3 shows a horizontal sectional view including the shower nozzle 1. Behind the slit 4 of the front cover 3 is a side wall 2 that serves as a movement guide for the shower nozzle 1.
4 and 24 are provided to face each other, and the shower nozzle 1 is guided by the side walls 24 and 24 so that it can be stably raised and lowered. By providing the side wall 24 behind the slit 4 in this manner, the internal mechanism is difficult to see through the slit 4, greatly increasing the effect of enhancing the appearance, and preventing fingers from touching the drive mechanism section 10. This improves safety, and furthermore, the rib effect of the entire cover 23 is exerted on the side wall 24, effectively increasing its strength. The shower nozzle 1 is fixed to a slider 9, and the slider 9 is guided up and down along a fixed guide 25. A rack gear 26 is fixed to the fixed guide 25 to smoothly move the slider 9 up and down. 27 is a fixed part to the wire 8, 28 is a pinion gear that meshes with the rack gear 26, and 29 is a pinion gear 28.
This is the axis that holds the . The height adjuster 13 has a structure in which the slide rod 16 is gripped by a pair of left and right levers 30 and 31, and is held elastically by a torsion coil spring 32 like a clothespin. By grasping the tip of the height adjuster 31 closely, the height adjuster 13 is made free with respect to the slide rod 16, and in this state, the height adjuster 13 can be moved to an arbitrary position. The structure for positioning the height adjuster 13 with respect to the slide rod 16 can be modified in various designs. Since the height adjuster 13 is located in the slit 4 and protrudes from the front cover 3, the positional relationship of the height adjuster 13 with respect to the shower nozzle 1 is easy to understand, and the position can be easily changed. Vessel 13
There is no need to form a dedicated slit 4, which is advantageous in terms of design and cost.
