Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shower head for a shower sprinkler used in a bathroom or the like.

[0002]

2. Description of the Related Art As is well known, a shower head for a shower sprinkler provided in a bathroom or the like has a water sprinkling plate formed therein, and a water sprinkling plate having a large number of small diameter sprinkling holes formed on the front surface thereof. The water spray plate is normally supported by a wall surface so that the water spray plate surface is directed obliquely downward so that the user's entire body can be sprayed with water.

By the way, in the shower head which is supported obliquely downward on the wall surface as described above, the hot and cold water accumulated in the water passage space in the shower head is discharged from the sprinkling holes even after the water is stopped on the upstream side. Since water drops droop down for a long time, there was a problem that the water stop was illusion that it was incomplete. Further, for this reason, there has been a problem that the water stopper is strongly operated more than necessary and causes a failure.

Therefore, in the hand shower disclosed in Japanese Patent Laid-Open No. 3-284367, a partition wall is provided in the internal space of the shower head, and a through hole is provided above the partition wall, so that the shower head is lowered from the through hole. The remaining water is kept from dripping.

Further, in the shower head disclosed in Japanese Utility Model Laid-Open No. 4-114450, a check valve that opens by water supply pressure is provided in the head so that the water can be stopped quickly after the water stop operation.

Further, in the shower head disclosed in Japanese Utility Model Laid-Open No. 5-9659, the diameter of the water spray holes in the peripheral portion of the water spray plate is made larger than that in the central portion, and the residual water in the head is completely drained in a short time. I am trying.

[0007]

However, the above-mentioned Japanese Unexamined Patent Application Publication No. 3-
In No. 284367, there is a problem in that a considerable amount of water actually droops down because the water above it droops down.

Further, in Japanese Utility Model Laid-Open No. 4-114450, there is a problem that fine dust and foreign matter in the water adhere to the check valve, which easily causes malfunction.

Further, in Japanese Utility Model Laid-Open No. 5-9659, there is a problem in that the residual water is wasted because the residual water can be drooped down in a short time, but the quantity does not change at all.

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above-mentioned problems. In a shower head provided with a sprinkler plate in which a large number of small diameter sprinkler holes are formed in the front surface of the water passage space, A partition wall for partitioning the space into an inner chamber and a water sprinkling chamber is provided, and a communication passage that connects the inner chamber and the water sprinkling chamber is provided in the partition wall, and a shower head is hung in the engagement passage in the communication passage. At least the downstream side face is provided with a net-like portion which is substantially horizontal.

Further, the present invention is characterized in that, in the above shower head for preventing water dripping, a plurality of communication passages having substantially the same height when the shower head is hooked on the hook are provided in the partition wall.

[0012]

When the shower head is hung on the locking device to stop the water, the downstream side surface of the mesh portion becomes substantially horizontal, so that the weight of the residual water in the inner chamber is applied to the mesh portion substantially evenly. As a result, the surface tension of the water acting on the downstream side surface of the mesh portion prevents the outside air from entering and the residual water when water is stopped can be retained in the inner chamber. In addition, even if multiple water passages are provided to secure sufficient water flow, each water passage should be at approximately the same height, and the weight of the remaining water should be applied equally to each water passage to maintain the residual water by surface tension. To enable.

[0013]

Embodiments of the present invention will now be described with reference to the drawings.
The shower head 1 shown in the embodiment of FIG. 1 is connected to the end of a flexible hose 2, and the shower head 1 is detachably attached to a locking tool 4 provided on a wall surface 3 of a bathroom or the like. Can be hung. A water-passing space 6 is formed inside the shower head 1, and a water-spraying plate 8 having a large number of small-diameter water-spraying holes 7 formed on the front surface thereof is fixed by screwing a peripheral edge portion 9 thereof.

Reference numeral 10 denotes a partition wall provided inside the water passage space 6 by sandwiching a peripheral edge portion inside the water spray plate 8 when the water spray plate 8 is screwed. The partition wall 10 divides the water passage space 6 into an inner chamber 11 Sprinkler room 1
The inner chamber 11 and the sprinkling chamber 12 are partially communicated with each other through the communication passage 13 while being divided into two and provided with a small-diameter cylindrical communication passage 13 in the central portion. A mesh-like portion 14 formed by adjoining a plurality of square through-holes adjacent to each other in a matrix in the communicating passage 13 is stretched in a film shape, and the mesh-like portion 14 hangs the shower head 1 on the locking tool 4. In the state of FIG. 1, at least the downstream side surface is formed to be substantially horizontal.

Therefore, when the water is stopped, the residual water in the sprinkling chamber 12 hangs down from the sprinkling holes 7, but the residual water in the inner chamber 11 is retained in the inner chamber 11 by the surface tension acting on the mesh portion 14. .

On the other hand, in the embodiment shown in FIGS. 2 to 4, the mounting portion 20 is integrally formed at the center of the water passage space 6, and the partition wall 10 is fixed to the mounting portion 20 with the screw 21. Will be
In this case, a pair of small-diameter cylindrical communication passages 1 are provided on both sides of the screw hole.
3 is provided. The pair of communication passages 13 are provided in the partition wall 10 so as to have the same height when the shower head 1 is hooked on the locking tool 4, and the mesh portions 14 are substantially horizontal in the respective communication passages 13. It is formed so that. When a plurality of communication passages 13 are provided as in this embodiment, the plurality of communication passages 13 are made to have the same height when the shower head 1 is hooked, so that the inner chamber 11 is formed in the mesh portion 14 in each communication passage 13.
The weight of the residual water inside is applied equally so that the residual water retention force due to the surface tension acts evenly. Since the inner diameter of the communication passage 13 and the size and shape of the mesh of the mesh portion 14 affect the magnitude of the surface tension, it is appropriately designed in consideration of the required amount of residual water such as the size of the inner chamber 11 and the like. To be done. Also,
Of course, the mesh portion 14 may be formed in a mesh shape by forming a large number of small holes.

[0017]

As described above, according to the structure of the present invention, since the residual water can be retained in the shower head by the surface tension, it is possible to reduce the amount of the residual water drooping when the water is stopped, and to improve the usability and the water quality. There is a beneficial effect that the wasteful outflow of can be suppressed.
