DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on embodiments. [Embodiment 1: First Invention] FIG. 1 is a view showing a main part (flowing water outlet) of a water purifier showing a first embodiment of the present invention. In the figure, 2 is a bottom case made of a resin member, 3 is a stainless net (mesh plate), and 4 is a net holder made of a resin member. As shown in FIG. 2A, the net 3 is provided with a large number of holes 3-2 having a diameter larger than that of the mesh 3-1. Although the holes of the mesh 3-1 are drawn large in FIG. 2, they are actually minute holes.

In this water purifier, when the water pressure is increased, the fluid resistance of the mesh surface 3-3 of the net 3 becomes large.
As shown in (a), the running water vigorously flows out from each of the large-diameter holes 3-2 to become the running shower water. At this time, since the running water hits the mesh surface 3-3 of the net 3 and is dispersed, it is possible to obtain the shower running water that is mixed neatly. Further, when the running water hits the mesh surface 3-3 of the net 3 and is dispersed, air is sucked in, so that shower running water of foam can be obtained.

On the other hand, when the water pressure is weakened, the fluid resistance of the mesh surface 3-3 of the net 3 becomes small, and as shown in FIG. 1 (b), the large diameter hole 3-2 and the mesh 3- Flowing water flows out through 1 and becomes direct current water. At this time, the flowing water hits the mesh surface 3-3 of the net 3 and is dispersed, so that it is possible to obtain the DC water that is neatly mixed. Further, when the flowing water hits the mesh surface 3-3 of the net 3 and is dispersed, the air is sucked in, and thus it is possible to obtain DC water in the form of foam.

[Second Embodiment: Second Invention] FIG. 3 is a view showing a main part (flowing water outlet) of a water purifier showing a second embodiment of the present invention. In this embodiment, on the running water inlet side of the net 3,
A lower shower plate (running water inflow plate) 5 made of a resin member is also arranged to hold down the net 3. The lower shower plate 5 is provided with a flowing water inflow hole 5-1 at a position facing the large diameter hole 3-2 of the net 3, and the outer edge surface portion of the flowing water inflow hole 5-1 on the net 3 side is provided. Is provided with a vertical wall 5-2.

FIG. 4A is a view of the lower shower plate 5 seen from above, and FIG. 4B is a view of the lower shower plate 5 seen from below. The lower shower plate 5 has a radius R1 and a radius R1.
A large number of flowing water inflow holes 5-1 are circumferentially provided at predetermined positions at positions 2 and radius R3. For the running water inflow hole 5-1 opened at the position of radius R1, the vertical wall 5-
2, a ring-shaped mountain 5-21 is provided. A ring-shaped mountain 5-22 is provided as a vertical wall 5-2 for the flowing water inflow hole 5-1 opened at the position of the radius R2. Flowing water inflow hole 5 opened at radius R3
For -1, as a vertical wall 5-2, a pedestal-shaped mountain 5-
23 are provided.

The ring-shaped mountain 5-21 has an inclined surface with respect to the flowing water inflow hole 5-1 side formed at the position of radius R1, and the ring-shaped mountain 5-22 has a position of radius R2. The surface on the side of the flowing water inflow hole 5-1 opened at is an inclined surface. In addition, the pedestal mountain 5-23 has an inclined surface on the side facing the flowing water inflow hole 5-1 formed at the position of the radius R3.

Further, the lower shower plate 5 is provided with a flange step portion 5-3 on the lower surface side thereof, and the flange step portion 5-3 has position restricting claws 5-31 and 5-32 for the net 3. Is provided. That is, as shown in FIG. 2A, the net 3 has semicircular cutouts 3-31, 3 on its outer peripheral portion.
-32 is formed. Net 3 is this cutout 3-3
1, 3 and 32 are attached to the lower shower plate 5 by aligning with the position restricting claws 5-31 and 5-32. As a result, the large-diameter hole 3-2 of the net 3 and the flowing water inflow hole 5-1 face each other with a predetermined gap. In Figure 3, this net 3
The lower shower plate 5 attached with the net 3 is dropped into the bottom case 2 with the net 3 on the lower side and press-fitted into the bottom surface portion of the bottom case 2 so that the net 3 can be held between the bottom surface portion of the bottom case 2 and the lower shower plate 5. It is held.

In this water purifier, when the water pressure is increased,
As shown in (a), running water from each running water inflow hole 5-1 of the lower shower plate 5 vigorously flows out from each large diameter hole 3-2 of the net 3 to become a running shower water. On the contrary,
When the water pressure is weakened, as shown in FIG. 3B, the running water from the running water inflow hole 5-1 of the lower shower plate 5 is provided on the outer wall surface of the running water inflow hole 5-1 to form a vertical wall 5-2.

[Third Embodiment: Third Invention] In the second embodiment, depending on the shape of the standing wall 5-2 provided on the lower shower plate 5,
The water pressure at the switching point from shower running water (DC water) to DC running water (shower running water) can be changed. Conversely speaking, the water pressure at the switching point is influenced by the shape of the vertical wall 5-2 provided on the lower shower plate 5, and when a predetermined water pressure is to be used as the switching point, how should the shape of the vertical wall 5-2 be changed? It is difficult to choose. Further, since the method is a method of obtaining direct-current water by flowing running water along the inclined surface of the standing wall 5-2, that is, a method of utilizing surface tension, the water pressure at the switching point is low and strong direct-current water is generated. Can't get Also, due to fluctuations in water pressure, it becomes shower running water or direct current water.

Therefore, in this embodiment, as shown in FIG. 5, the vertical wall 5-2 is removed from the lower shower plate 5 to form a lower shower plate 5 ', and the net 3 is rotated to make the net 3 larger. The relative position between the bore 3-2 and the flowing water inflow hole 5'-1 of the lower shower plate 5'can be adjusted. That is, in this embodiment, by rotating the net 3, the relative position between the large-diameter hole 3-2 of the net 3 and the running water inflow hole 5'-1 of the lower shower plate 5'is changed from the matched state to the non-matched state. It is possible to adjust from the non-matching state to the matching state. Although the mechanism for rotating the net 3 is not shown in this embodiment, it can be embodied by providing an adjusting knob as in Embodiment 4 described later.

In this water purifier, as shown in FIG. 5A, the large-diameter hole 3-2 of the net 3 and the lower shower plate 5 '.
If the relative positions of the water flow inflow holes 5'-1 of the lower shower plate 5'are matched, the water flow from the water flow inflow holes 5'-1 of the lower shower plate 5'flows out from the large diameter holes 3-2 of the net 3. , Shower running water. On the other hand, as shown in FIG. 5B, the large-diameter hole 3-2 of the net 3 and the lower shower plate 5 '
If the relative position with the flowing water inflow hole 5′-1 of No. 3 is set to be in a non-matching state, the flowing water from the flowing water inflow hole 5′-1 of the lower shower plate 5 ′ will be dispersed by hitting the mesh surface 3-3 of the net 3. 3 flowed through the large-diameter hole 3-2 and the mesh 3-1 and became finely mixed foam DC water.

In this water purifier, since it is only necessary to provide the net 3 and the lower shower plate 5'as the flowing water switching portion, a large space in the thickness direction is not required,
It is possible to promote thinning. Further, in this water purifier, the switching point between the direct current water and the shower running water can be made clear, and the direct current water and the shower running water can be fitted to each other. Further, when the relative positions of the large-diameter hole 3-2 of the net 3 and the flowing water inflow hole 5'-1 of the lower shower plate 5'are not matched, the water pressure at the switching point at which DC water is switched to shower flowing water is Since it is expensive, strong direct current water can be obtained.
