Description

[Detailed description of the invention] 【Technical field】

The present invention relates to a shower device installed in a bathroom or the like, and more particularly to a shower device whose shower head can be moved by water pressure.

[Background technology]

Showers are increasingly being used by small families and single people as a convenient means of bathing because they are easy to prepare for bathing, and they save water and energy.
In addition, due to social needs for health promotion, the skin stimulation and thermal effects of the spray pressure of showers are attracting attention. In other words, showering not only has a thermal effect, but also stimulates the skin due to the spray pressure, and this stimulation increases blood flow, which improves the health and beauty of the circulatory system, respiratory system, autonomic nervous system, etc. It is attracting attention because it can activate various functions that are deeply related to each other, and is effective for relaxing the mind and body, relieving fatigue, and improving beauty. Against this background, shower devices devised to provide more effective stimulation effects have also been proposed. An example is shown in FIG.
A wire 3 is stretched between a pair of pulleys 31, 31 around a piston 30 disposed in a cylinder 3.
2, and a slider 33 which is provided with a pair of shower heads 1, 1 on this wire 32.
A switching valve 4 formed by a four-way valve is connected to both ends of the cylinder 3, one of the shower heads 1, 1, and a hot water supply source 6. Note that the other shower head 1 is connected to the hot water supply source 6 without going through the switching valve 4. The switching valve 4 here is mechanically switched to change the flow path each time the piston 30 reaches both ends of the cylinder 3, for example, and when the flow rate adjustment valve 5 is opened in the state shown by the solid line in the figure. As hot water is supplied to the upper end of the cylinder 3, the piston 30 descends, and in conjunction with this, the hot water in the lower part of the cylinder 3 is supplied to the shower head 1 via the switching valve 4, and at the same time, the slider 33 Both shower heads 1, 1 provided at the top move upward. When the piston 30 reaches the lower end of the cylinder 3 and the switching valve 4 is switched, hot water is supplied below the cylinder 3 and the piston 30 rises, lowering both shower heads 1 and 1 at the same time. , the hot water in the upper part of the cylinder 3 is supplied to the shower head 1 connected to the switching valve 4. In other words, both shower heads 1, 1 repeatedly move up and down to spray hot water, making it possible to stimulate the skin over a wide area with a small amount of hot water. However, in the above conventional example, the hot water injected from one shower head 1 is the hot water used to move both shower heads 1 up and down, and is not directly connected to the hot water supply source 6. It has the disadvantage that the injection pressure is low and it cannot provide effective skin stimulation. However, in order to compensate for this point, in the conventional example described above, a shower head 1 directly connected to the hot water supply source 6 is also provided. Because of these differences, the balance is disrupted and this actually causes discomfort. Furthermore, since the injection pressure and the moving speed of both shower heads 1, 1 are linked, it is not possible to move them slowly while the injection pressure is kept high. Furthermore, the stroke of the vertical movement of the shower heads 1, 1 is lengthened,
If the shower is applied from the shoulders to the calves, there is a limit to the driving speed of the shower heads 1, 1, so the time required for one round trip up and down will be longer, and in the winter, the shoulders, which should be sufficiently heated, will be affected. It also has the problem of not getting warm.

[Purpose of the invention]

The present invention has been made in view of these points, and its purpose is to provide a shower device that can effectively provide a thermal effect and skin stimulation.

[Disclosure of the invention]

However, the present invention provides a cylinder that reciprocates a piston using hot water supplied through a switching valve;
The shower head is equipped with a first shower head that reciprocates in conjunction with the reciprocating movement of the piston, and a second shower head that is connected to the cylinder via a switching valve and is supplied with hot water discharged from the cylinder. The first shower head is characterized in that the hot water supply route to the second shower head is separate from the first shower head, and the movable first shower head is directly supplied with hot water from the hot water supply source. The discharged hot water is injected from a second shower head, which is separate from the first shower head, especially for a thermal effect. Hereinafter, the present invention will be described in detail based on the embodiment shown in FIG. The wire 32 is connected and a slider 33 provided with a pair of shower heads 1, 1 is attached to the wire 32, and the switching valve 4, which is a four-way valve, is connected to both ends of the cylinder 3. This is the same as the conventional example. However, a permanently installed shower head 2 is connected to the remaining port of the switching valve 4, which is also connected to a hot water supply source 6, so that the hot water discharged from the cylinder 3 is injected from this shower head 2. This differs from the conventional example in that the hot water supply source 6 is connected to the pair of shower heads 1, 1 through a separate system without using the switching valve 4. The shower head 2 is preferably installed at a height where the hot water it sprays hits the user's shoulders. In the figure, 10 is a flexible hose. Since the switching valve 4 is configured to be mechanically switched to change the flow path each time the piston 30 reaches both ends of the cylinder 3, the pair of shower heads 1, 1 can inject hot water. It moves up and down while stimulating the skin over a wide area. Since both shower heads 1, 1 are connected to the hot water supply source 6 without going through the cylinder 3, they have sufficient injection pressure to provide good skin stimulation, and the injection pressure in both shower heads 1, 1 is The pressures are equal. At the same time as the hot water is injected from the shower heads 1 and 1, the shower head 2 injects hot water into the cylinder 3.
The warm water used to drive the piston 30 is sprayed, and even when both shower heads 1, 1 are giving skin irritation to the calves, the water is sprayed from the shower head 2, hitting the shoulders and along the body. It is heated by falling hot water. Therefore, it can be used comfortably even when the room temperature is low, such as in winter. The injection pressure in the shower heads 1, 1 can be controlled by a flow rate regulating valve 5' disposed in the hot water supply path. Also shower head 1,
The speed of the reciprocating motion of shower head 1 can be adjusted by a flow rate regulating valve 5 disposed in the hot water supply path leading to switching valve 4, regardless of the injection pressure from shower heads 1,1. Note that the switching valve 4 may not be one that performs the switching operation mechanically as described above, but may be one that performs the switching operation electrically, and is not particularly limited. Also, the cylinder 3 is connected through the switching valve 4.
The supply route for hot water sent to the bathtub and the supply route for hot water sent to the shower heads 1, 1 do not need to be completely independent, and may be branched from a single hot water supply pipe. It is sufficient that hot water is not sent to the shower heads 1 through the switching valve 4. However, when both systems are completely independent, the hot water supplied to the shower head 2 can be used as fresh water, and the hot water supplied to the shower heads 1 and 1 through the cylinder 3 can be recycled and reused, resulting in total water savings.・Energy saving effect can be further enhanced.

【Effect of the invention】

As described above, in the present invention, since hot water is directly supplied from the hot water supply source to the movable second shower head, the spray pressure is sufficient to effectively stimulate the skin. In addition, it is possible to independently adjust the injection pressure and the reciprocating speed, and the hot water supplied to the cylinder for reciprocating the first shower head is supplied to the second shower head. Since the hot water is jetted from the shower head, it saves water and energy, and the hot water jetted from the second shower head can provide a sufficient thermal effect even when the hot water is low.
It can satisfy both the thermal effect and skin irritation, and exhibits high effects on health promotion and beauty.
