Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a shower head.

[0002]

2. Description of the Related Art Conventionally, since chlorine contained in tap water has a bad effect on hair and sensitive skin type people, replace the shower head with a built-in chlorine removal filter to sprinkle chlorine-removed water. The shower head with a built-in chlorine removal filter always sprays chlorine-free water, so if you want to use tap water (raw water) containing chlorine for cleaning, etc. There is a problem that the filter cannot be used and the life of the chlorine removal filter is shortened because the filter always passes through the filter.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned conventional problems, and it is possible to switch between raw water and chlorine-removed water, and to use the raw water satisfactorily at the time of cleaning or the like. The first gist of the invention is to provide a head. The first gist is that an inner sprinkler plate for sprinkling raw water that does not pass through the dechlorination filter is provided at the center of the outer sprinkler plate for sprinkling chlorine-removed water through a built-in dechlorination filter. A changeover switch for switching between watering from the outer watering plate and watering from the inner watering plate is provided.
A second point is that the range of watering from the inner watering plate is set to be smaller than the range of watering from the outer watering plate. A third point is that the diameter of the water sprinkling hole of the inner water sprinkling plate is formed larger than the diameter of the water sprinkling hole of the outer water sprinkling plate. A fourth gist is that the number of watering holes of the inner watering plate is set to be smaller than the number of watering holes of the outer watering plate.

[0004]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional configuration diagram of a shower head according to the present embodiment. The shower head 1 includes a head main body 2 and a handle 3 that forms a water channel and is removably connected to the head main body 2. An outer sprinkling plate 4 having sprinkling holes 4a, 4a, 4a is attached to the discharge side of the head main body 2, and a dechlorination filter 6 is built inside the outer sprinkling plate 4. The dechlorination filter 6 is disposed in the outer passage 5.

At the center of the outer sprinkling plate 4, an inner sprinkling plate 7 having raw water sprinkling holes 7a, 7a, 7a is attached. The raw water passage 8 and the outer passage 5 are each provided with a packing 9 so as to be opened and closed by a ball 10, and the ball 10 is centered on a shaft 11. A seesaw type changeover switch 12 is connected to the shaft 11, and by operating the changeover switch 12, the ball 10 is moved around the shaft 11 to a position where the outer passage 5 is closed. Alternatively, the raw water passage 8 can be moved to a closed position. Therefore,
By operating the changeover switch 12, the chlorine-removed water can be sprinkled from the outer watering plate 4 through the dechlorination filter 6, and the raw water can be sprinkled from the inner watering plate 7 by switching with the changeover switch 12. It is configured.

In the state shown in FIG. 1, the ball 10 is in contact with the packing 9 at the inlet of the raw water passage 8 to close the raw water passage 8. In the state shown in FIG. Tap water is supplied, the tap water is passed through a dechlorination filter 6 to remove chlorine, and water is sprinkled from the water sprinkling holes 4a of the outer water sprinkling plate 4 as chlorine-removed water.

In this embodiment, as shown in the figure, the water spray range α from the inner water spray plate 7 is set so as to be smaller than the water spray range β from the outer water spray plate 4. The diameter of the raw water sprinkling hole 7a of the plate 7 is formed to be larger than the diameter of the water sprinkling hole 4a of the outer water sprinkling plate 4, and the number of the raw water sprinkling holes 7a of the inner water sprinkling plate 7 is The number is set to be smaller than the number of the water sprinkling holes 4a.

In such a structure, when the face is washed or the hair is washed, the raw water passage 8 is closed and the chlorine-free water is sprinkled from the outer water sprinkling plate 4 so that the hair and the like are adversely affected by the chlorine-free water. It is possible to wash the hair well without the need, and when cleaning the bathroom, etc., the outside passage 5 is closed by operating the changeover switch 12,
Tap water can be sprinkled from the raw water passage 8 through the inner sprinkling plate 7. At this time, the inner sprinkling plate 7 is set to have a narrow sprinkling range α, a large diameter of the sprinkling holes 7 a, and a small number. Therefore, water can be spouted out in a spot to be cleaned so that cleaning can be performed satisfactorily. As described above, since raw water can be used at the time of cleaning, etc., since tap water does not always pass through the dechlorination filter 6, the life of the dechlorination filter 6 can be extended accordingly. . In addition, by using raw water at the time of cleaning or the like, since chlorine remains in raw water, there is an advantage that mold, germs and the like are hardly generated.

[0009]

According to the shower head of the present invention, an inner sprinkler plate for sprinkling raw water that does not pass through the dechlorination filter is provided at the center of the outer sprinkler plate for sprinkling chlorine-removed water through a built-in dechlorination filter. By providing a changeover switch that switches between watering from the outer watering plate and watering from the inner watering plate, it is used by spraying chlorine-removed water from the outer watering plate through a dechlorination filter during hair washing and the like. In addition, when cleaning, etc., it can be switched by operating the changeover switch to sprinkle the raw water from the inner watering plate, and it is possible to distinguish and use chlorine-free water and raw water according to the use scene, The life of the dechlorination filter can be extended.

[0010] Further, the range of watering from the inner watering plate is as follows:
By being set to be narrower than the watering range from the outer watering plate, when watering the raw water from the inner watering plate at the time of cleaning or the like, the watering range becomes narrower, and the watering is applied to the cleaning location spotwise. Thus, the cleaning operation can be performed satisfactorily. In addition, by using raw water at the time of cleaning or the like, since chlorine remains in raw water, there is an advantage that mold, germs and the like are hardly generated.

Further, since the diameter of the water sprinkling holes of the inner water sprinkling plate is formed to be larger than the diameter of the water sprinkling holes of the outer water sprinkling plate, the raw water from the inner water sprinkling plate becomes large, and it is necessary to clean the water. In this way, the raw water can vigorously collide with the target location to clean well.

Further, since the number of water holes in the inner water plate is set to be smaller than the number of water holes in the outer water plate, the raw water is spouted from the small number of water holes as a strong water flow for cleaning. This has the effect of being able to come into contact with a place or the like, so that a cleaning operation or the like can be performed satisfactorily.
