DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower head, and more particularly, to a shower head which mixes air to improve a feeling of use.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a shower head in which air is mixed with hot and cold water by forming a water spraying section in two stages.

[0003]

The conventional shower head has a structure in which air is always mixed therein, and there is a problem that only a single feeling of use can be obtained. An object of the present invention is to provide a configuration that provides a new function to a conventional aerated shower head. An object of the present invention is to control mixing of air into hot and cold water with a simple mechanism, and to discharge water with a different feeling of use. Is to provide an aerated shower head that can be realized by one shower head.

[0004]

According to a first aspect of the present invention, there is provided a shower head provided with an aeration unit for mixing air into hot and cold water in a shower head sprinkling unit. And a mechanism for opening and closing the air inflow path. According to the present invention, by opening and closing the air inflow path, it is possible to realize, with a single shower head, water discharge with different usability, that is, discharge of hot water with air mixed therein and water with no air mixed therein.

[0005]

FIG. 1 is a cross-sectional view of an example in which an air inflow path communicated with the outside is opened in the present aerated shower head sprinkler. FIG. 2 is a sectional view showing an example in which the air inflow path communicated with the outside in FIG. 1 is closed. 1 and 2, a water sprinkling section 2 provided in a shower head 1 has a primary sprinkling section 4 having a plurality of holes 3 and a hole having the same number of holes as the number of holes in the primary sprinkling section 4 and having a larger hole diameter. 5 is provided with a secondary sprinkling section 6 having a gap 5 between the primary sprinkling section 4 and the secondary sprinkling section 6 and an air gap 7 communicating with the outside. The angle is set.

[0006] O-rings 9a and 9b are arranged on the outer periphery of the primary sprinkling section 4 and the secondary sprinkling section 6, and a lid 10 is arranged on the outer periphery. The lid 10 is configured to be movable in the cross-section left and right direction so that the gap 7 can be opened and closed, and to be in close contact with the O-rings 9a and 9b when the gap 7 is closed. A packing 14 is disposed between the primary sprinkling section 4 and the shower head main body 11, and the primary sprinkling section 4, the secondary sprinkling section 6, and the packing 1 are provided.
4 is configured to be fixed to the shower head main body 11 by screws 13.

Further, the primary water sprinkling section 4 and the secondary water sprinkling section 6 may have a fitting section 8 for matching the positions of the holes 3 and 5. Alternatively, the primary sprinkling section 4 and the secondary sprinkling section 6 may be formed integrally. Furthermore, the hole 3 of the primary sprinkling plate 4 may be configured to have an appropriate angle. Further, the upstream side hole end 3a of the primary water sprinkling section 4 may be configured to have a taper. Furthermore, a hole end 5a of the hole 5 in the surface 6a facing the primary watering part 4 of the secondary watering part 6
May be configured to have a taper.

In FIGS. 1 and 2, the primary water sprinkling part 4 and the secondary water sprinkling part 6 are arranged by the fitting part 8 so that the positions of the holes 3 and 5 coincide with each other. The hot and cold water flowing in the shower head main body 11 is squeezed by the holes 3 of the primary sprinkling section 4 to increase the flow velocity, and is discharged into the holes 5 of the secondary sprinkling section 6. In FIG. 1, since the lid 10 is at a position where the gap 7 communicates with the outside, the discharged hot water is conducted to the hole 5 while entraining air from the gap 7. The hot and cold water mixed with air is sprinkled at an appropriate water discharge angle by the angle provided in the hole 5 while maintaining the flow velocity to some extent by increasing the apparent volume. As a result, the sprinkled hot and cold water is sprinkled with both a stimulating feeling due to the flow velocity maintained to some extent and a softness due to the air being mixed.

On the other hand, in FIG. 2, the lid 10 is located at a position where the gap 7 closes a path communicating with the outside, so that the discharged hot water flows into the hole 5 without entraining air from the gap 7. The hot and cold water into which air is not mixed is sprinkled at an appropriate water discharge angle depending on the angle provided in the hole 5 with the flow velocity reduced according to the cross-sectional area of the hole 5. As a result, the sprinkled water becomes a gentle sprinkle with little irritation. Further, by adjusting the angle between the hole 3 of the primary sprinkling section 4 and the hole 5 of the secondary sprinkling section 6, it is possible to adjust the degree of turbulence when the hot and cold water discharged from the hole 3 is conducted to the hole 5, The amount of air entrainment can be adjusted.

Further, by providing a taper at the upstream side hole end 3a of the primary sprinkler 4, the flow of hot and cold water at the time of squeezing becomes smoother. Further, by providing a taper at the hole end 5a on the surface 6a side of the secondary sprinkling section 6 facing the primary sprinkling section 4, the inside of the hole 5 of the secondary sprinkling section 6 of water spouted from the hole 3 of the primary sprinkling section 4 is formed. Conduction to the device becomes smoother. 1 and 2, the gap 7 is configured to communicate with the outside over the entire circumference. However, the communication portion with the outside of the gap 7 is limited to one or a plurality of places, and the cover is opened and closed locally. May be arranged.

[0011]

According to the present invention, the following effects are exhibited by the above configuration. In claim 1, by opening and closing the air inflow path,
Since the spouting of hot and cold water mixed with air and the spouting of hot water not mixed with air can be performed, the spouting with different usability can be realized with one shower head.
