Description

[0001]
[Industrial applications]
The present invention relates to a shower head of a shower sprinkler used in a bathroom or the like.
[0002]
[Prior art]
As is well known, a shower head of a shower sprinkler provided in a bathroom or the like is provided with a water sprinkling plate having a water passage space formed therein and a large number of small water sprinkling holes formed in front of the shower head. It is supported by a wall or the like so that the plate surface faces diagonally downward, so that water can be sprayed over the entire body of the user.
[0003]
By the way, in the shower head supported diagonally downward on the wall surface as described above, even after the water stops on the upstream side, it takes a long time until the hot water pooled in the water passage space in the shower head is discharged from the water sprinkling hole. Since the water drops droop, there is a problem that the water stop is illusioned to be incomplete and a complaint is generated. In addition, there has been a problem that the water stopcock is more strongly stopped than necessary and causes a failure.
[0004]
In the hand shower disclosed in Japanese Patent Application Laid-Open No. 3-284673, a partition is provided in the interior space of the shower head, and a through hole is provided in the upper portion of the partition, so that residual water below the through hole in the shower head is provided. To prevent it from sagging.
[0005]
Further, in the shower head disclosed in Japanese Utility Model Laid-Open No. 4-114450, a water check valve is provided in the head to open the valve by water pressure so that water can be stopped quickly after the water stop operation.
[0006]
Furthermore, in the shower head disclosed in Japanese Utility Model Laid-Open No. 5-9659, the water sprinkling hole at the peripheral portion of the water sprinkling plate is made larger in diameter than that at the central portion so that the residual water in the head can be completely drained in a short time. I have.
[0007]
[Problems to be solved by the invention]
However, in the above-mentioned Japanese Patent Application Laid-Open No. 3-284673, there is a problem that a considerable amount of water actually drips because water above the through-hole drips.
[0008]
Further, in Japanese Utility Model Laid-Open No. 4-114450, there is a problem in that fine dust and foreign matter in water adhere to the check valve, which easily causes a malfunction.
[0009]
Further, in Japanese Utility Model Laid-Open No. 5-9659, there is a problem that the dripping of residual water can be shortened in terms of time, but the amount does not change at all, so that water is wasted.
[0010]
[Means for Solving the Problems]
The present invention is intended to solve the above-described problems, and in a shower head provided with a watering plate having a large number of small-diameter watering holes formed in front of the watering space, the watering space is divided into an inner chamber and a watering chamber. A partitioning wall is provided, and the partitioning wall is provided with a communication path communicating the inner chamber and the watering chamber, and at least in a state where the shower head is hung on the locking tool so that the watering plate surface is obliquely downward. A mesh portion in which the downstream side surface is substantially horizontal is provided in the communication path .
[0011]
Further, in the present invention, in the above-mentioned shower head for preventing water dripping, a plurality of communication passages having substantially the same height in a state where the shower head is hung on a hook so that a sprinkling plate surface faces obliquely downward are provided in the partition wall. It is characterized by.
[0012]
[Action]
By stopping the water with the shower head hung on the locking device, the downstream side surface of the mesh portion becomes almost horizontal, so that the weight of the residual water in the inner room is applied to the mesh portion almost uniformly without any difference in elevation. The outside air does not enter due to the surface tension of the water acting on the downstream side surface of the mesh portion, so that the residual water at the time of water stoppage can be retained in the inner chamber.
In addition, even when providing a plurality of water passages to secure the water flow, the water passages should be approximately the same height, and the weight of the remaining water should be equally applied to each water passage to maintain the residual water by surface tension. Enable.
[0013]
【Example】
Next, embodiments of the present invention will be described with reference to the drawings.
A shower head 1 shown in the embodiment of FIG. 1 is connected to a distal end of a flexible hose 2, and the shower head 1 is detachably attached to a locking tool 4 protruding from a wall 3 of a bathroom or the like. Can be hung. A water passage space 6 is formed inside the shower head 1, and a water spray plate 8 having a large number of small-diameter water holes 7 is fixed to the front surface thereof by screwing a peripheral edge 9 thereof.
[0014]
Numeral 10 is a partition wall provided in the water passage space 6 by sandwiching a peripheral portion inside the water sprinkle plate 8 at the time of screwing the water sprinkle plate 8. In addition, a small-diameter cylindrical communication passage 13 is provided at the center, and the inner chamber 11 and the sprinkling chamber 12 are partially communicated via the communication passage 13. Then, a mesh portion 14 formed by forming a large number of square through holes adjacent to each other in a matrix in the communication passage 13 is stretched in a film shape, and the mesh portion 14 hangs the shower head 1 on the locking member 4. In the state of FIG. 1, at least the downstream side surface is formed to be substantially horizontal.
[0015]
For this reason, while the remaining water in the watering chamber 12 hangs down from the watering holes 7 when water is stopped, the remaining water in the inner chamber 11 is retained in the inner chamber 11 by surface tension acting on the mesh portion 14.
[0016]
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 10 is fixed to the mounting portion 20 by screws 21. In this case, a pair of small-diameter cylindrical communication passages 13 are provided on both sides of the screw hole. The pair of communication passages 13 are provided in the partition wall 10 so as to be at the same height in a state where the shower head 1 is hung on the locking member 4. It is formed so that it becomes. In the case where 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 mesh portion 14 in each communication passage 13 has The remaining water is equally weighted so that the residual water retention force due to 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 surface tension, the design is appropriately made in consideration of the required amount of remaining water such as the size of the inner chamber 11 and the like. Is done. In addition, it is a matter of course that the mesh portion 14 may be formed in a mesh shape by forming a large number of small holes.
[0017]
【The invention's effect】
As described above, according to the configuration of the present invention, the residual water can be held in the shower head by surface tension, so that the amount of dripping of the residual water at the time of stopping water can be reduced, the usability is improved, and the wasteful outflow of water is improved. There is a beneficial effect that can be suppressed.
