BACKGROUND OF THE INVENTION
This invention is invention regarding the structure of the watering part of the shower head attached to the front-end | tip of water supply pipe lines, such as a bathroom vanity.
[0002]
[Prior art]
Conventionally, a shower head is attached to the tip of a water supply line such as a wash basin, a plurality of water spray holes are drilled in the water spray plate at the tip of the shower head, and hot water supplied from the water tap to the shower head is supplied to the water spray holes. The water was divided into shower water via a water spray and ejected from the water spray plate of the shower head. At that time, if the diameter of the water spray hole of the water spray plate is large, the shower water becomes thick and vigorous. The hot water jumped over a wide area. If the diameter of the water spray hole of the water spray plate is set to be small in order to solve the above problem, fine dust contained in the hot water supplied to the shower head is likely to clog the water spray hole with a small diameter of the water spray plate, and the shower water is The pressure in the shower head inside the water spray plate is increased, and shower water sprayed from the water spray holes may be ejected in an unintended direction.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and the shower water ejected from the water spray plate of the shower head prevents splashing of hot water at the shower water landing position, and the water spray hole of the water spray plate is also clogged. It is an object of the present invention to provide a structure of the watering portion of a shower head that is prevented.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the structure of the water spray portion of the shower head according to claim 1 of the present invention is provided with a water spray plate 2 at the water outlet 1a of the shower head 1, and the water spray holes 3 are arranged in a ring in the water spray plate 2. A plurality of sprinkling hole arrays 4 formed concentrically are provided, and the diameter of the sprinkling holes 3 of the plurality of sprinkling hole arrays 4 is changed from the sprinkling hole array 4 in the central portion to the sprinkling hole array 4 in the outer peripheral portion. The inner surface 2a of the water spray plate 2 is inclined in the direction of water discharge from the outer peripheral edge to the central portion . As a result, the hot water supplied from the shower head 1 is divided by the large number of water spray holes 3 of the water spray plate 2 and ejected from the water spray plate 2 as shower diversions d (d ₁ , d ₂ ). A plurality of sprinkling hole arrays 4 formed by arranging the holes 3 in a ring shape are arranged concentrically, and the diameter of the sprinkling holes 3 of the plurality of sprinkling hole arrays 4 is changed from the sprinkling hole array 4 in the center to the outer peripheral portion. The shower diversion d ejected from the large number of water spray holes 3 of the water spray plate 2 is gradually reduced from the central part toward the outer peripheral part of the shower water D. When the shower water D lands on the wash bowl 15 or the like, the flow rate is small in the shower diversion d ₂ ejected from the small-diameter sprinkling holes 3b located at the outer peripheral edge of the shower water D. So the bounce of hot water is a small one Rukoto can, Although shower diverter d ₁ ejected from the large nozzle holes 3a having a diameter positioned at the center of the shower water D is hot water bounce many flow large, hot water of the outer rebounding which scatters are intended to block the shower diverter d ₂ is located on the outer peripheral edge of the shower water D is scattered outside, it is capable of suppressing the hot water splashing shower water D significantly.
[0005]
Further , since the large- diameter sprinkling hole 3a has a large flow rate for jetting hot water, the flow A of hot water flowing toward the sprinkling hole 3a having a large diameter is the mainstream in the hot water flow from the shower head 1 to the sprinkling plate 2. Further, the inner surface 2a of the water spray plate 2 protrudes in the water discharge direction from the outer peripheral edge where the small water sprinkling hole 3b is disposed toward the central portion where the large water sprinkling hole 3a is disposed. Thus, the hot water flow B toward the water spray hole 3a having a large diameter along the inner surface 2a of the water spray plate 2 is formed. Since the fine dust 5 contained in the hot water is greatly affected by the hot water flows A and B toward the sprinkling hole 3a having a large diameter, the dust 5 is carried to the hot water flows A and B on the water spray plate 2. It moves to the center and is ejected from the large-diameter sprinkling hole 3a to the outside of the shower head 1, and prevents the dust 5 from clogging the small-diameter sprinkling hole 3b.
[0006]
Moreover, the structure of the watering part of the shower head which concerns on Claim 2 of this invention is characterized by forming at least the watering board 2 with resin in Claim 1 . Thereby, it can form easily on manufacture and can also reduce cost.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.
[0008]
An example of an embodiment of the present invention is shown in FIGS. As shown in FIG. 4, an operation lever 7 and a receiving portion 8 are formed on the mounting base 6 at the rear of the wash bowl 15 of the vanity, and a water supply pipe (not shown) is provided inside the vanity. It is what is arranged. A shower body 10 composed of a cylindrical handle portion 9 and a shower head 1 described later is detachably mounted on the receiving portion 8. In that case, the handle portion 9 of the shower body 10 is fitted into the receiving portion 8 so as to be inserted from above. Of both ends of the handle portion 9 in the longitudinal direction, one end is connected to the shower head 1 and the other end is connected to a water supply hose (not shown) extending from the water supply conduit. That is, hot water is supplied from the water supply pipe line to the shower head 1 through the water supply hose and the handle portion 9. Hereinafter, the direction of hot water supplied from the water supply pipe to the shower head is the direction of water discharge (arrow X in FIG. 5). For example, the handle portion 9 is connected to the shower head 1 at the front end in the water discharge direction and is fitted to the receiving portion 8 at the rear end in the water discharge direction. The operation lever 7 adjusts hot water supplied to the shower head 1 (temperature, flow rate, etc.).
[0009]
The shower head 1 is formed in a substantially elbow tube which is bent substantially vertically and has openings (discharge ports 1a, supply ports 1b) at both ends. The openings at both ends (discharge port 1a, supply port 1b) are such that the discharge port 1a is located at the front end in the water discharge direction and the supply port 1b is located at the rear end. In addition, although the push button 14 is formed in the surface of the shower head 1, this operates switching of the flow path to the straight water discharging part 11 and the shower water discharging part 12 mentioned later. The supply port 1b is rotatably attached to the front end of the handle portion 9 in the water discharge direction and the outer peripheral direction of the supply port 1b. On the other hand, the discharge port 1a has a thread 1c extending in the outer peripheral direction. And the watering board attachment edge 13 mentioned later is attached.
[0010]
The sprinkler plate attachment edge 13 is formed in a cylindrical shape, and is a connecting member between the shower head 1 described above and a sprinkler plate 2 described later. The sprinkler plate mounting edge 13 has a cylindrical opening at the front and rear ends in the water discharge direction, and is fixed to the discharge port 1a of the shower head 1 at the rear end in the water discharge direction, and is fixed to the water spray plate 2 at the front end in the water discharge direction. is there.
[0011]
The water spray plate 2 is formed in a substantially conical plate shape with a central portion protruding as compared with the outer peripheral edge. The outer peripheral edge of the water spray plate 2 is connected to the front end of the water spray plate mounting edge 13 in the water discharge direction, and the water spray plate 2 is fixed so as to cover the front end opening of the water spray plate mounting edge 13 in the water discharge direction. . At this time, the substantially conical plate-shaped watering plate 2 is fixed so that the center part protrudes in the water discharging direction. Hereinafter, the details of the shape of the watering plate 2 will be described. An opening 11a is formed in the central portion of the water spray plate 2, and a circular pipe extending in the water discharge direction is formed along the outer edge of the opening 11a. A straight water discharge section 11 is formed from the opening 11a and the circular pipe. ing. Moreover, the shower water discharging part 12 is formed from the outer peripheral edge of the straight water discharging part 11 to the outer peripheral edge of the water spray plate 2. That is, the water spray plate 2 is composed of the straight water discharge portion 11 and the shower water discharge portion 12. A mesh lid 11c is attached to the opening 11a of the straight water discharger 11 so as to cover the opening 11a. On the other hand, a large number of water spray holes 3 are formed in the shower water discharger 12. There is a pattern in the arrangement of the numerous water spray holes 3, and a plurality of water spray holes 3 are annularly arranged around the center of the water spray plate 2 to form the water spray hole array 4. A plurality of water spray hole rows 4 are arranged concentrically from the portion to the outer periphery. And the sprinkling hole 3a whose diameter is larger as the sprinkling hole 3 of the sprinkling hole row 4 close to the center part of the sprinkling plate 2 among the plurality of sprinkling hole rows 4 arranged concentrically. The sprinkling holes 3b of the sprinkling hole row 4 close to the outer peripheral edge are made smaller in sprinkling holes 3b. In the shower spout 12, the sprinkling plate 2 has a substantially conical plate shape, and the sprinkling hole 3 a having a large diameter is located at the front of the spout direction, and the sprinkling hole 3 b having a small diameter is located at the rear of the spout direction. is there.
[0012]
When using the shower body 10 configured as described above, hot water can be supplied to the shower head 1 from the water supply pipe line by operating the operation lever 7. And the hot water supplied to the shower head 1 is distributed to the straight water discharging part 11 and the shower water discharging part 12 by operating the push button 14 of the shower head 1. First, when the hot water supplied to the shower head 1 is distributed to the straight water discharge part 11, the said hot water is ejected as straight water from the opening 11a. Next, when the hot water supplied to the shower head 1 is distributed to the shower water discharger 12, the hot water is ejected from the shower water discharger 12 as shower water D. Here, the shower water D refers to an aggregate of shower diverts d ejected from a large number of water spray holes 3 formed in the water spray plate 2. As described above, the water sprinkling holes 3 formed in the shower spout 12 have a plurality of sprinkling hole arrays 4 having a diameter of the sprinkling holes 3 from the sprinkling hole array 4 at the center to the sprinkling hole array 4 at the outer periphery. Accordingly, the shower diversion d is formed so as to gradually become narrower from the central portion of the shower water D toward the outer peripheral portion.
[0013]
The shower water D is ejected toward a wash bowl or the like, and when the shower water D lands on the wash bowl, the hot water rebounds from the impact. In the case of this example, this rebound is minimized. That is, the shower diversion d ₂ ejected from the small-diameter sprinkling hole 3b located at the outer peripheral edge of the shower water D is formed into a thin one with a small flow rate, and the shower diversion d _{2 at} the outer peripheral edge of the shower water D is Even if it hits a wash bowl etc., it does not bounce so much because there is little impact. On the other hand, the shower diversion d ₁ ejected from the large-diameter sprinkling hole 3a located at the center of the shower water D has a large flow rate and is thick. It is easy. However, since the shower diversion d ₂ is located at the outer periphery of the shower water D as described above, the hot water bounced off from the shower diversion d ₁ at the center of the shower water D interferes with the shower diversion d ₂ , It is wrapped so that it does not fly outside the water D. In this way, it is intended to reduce the rebound of the hot water of the shower water D.
[0014]
Further, in this example, even if the hot water supplied to the shower head 1 contains fine dust 5, the water spray hole 3 is not blocked. In this example, as described above, among the large number of water sprinkling holes 3 drilled in the shower spout 12, a sprinkling hole 3 a having a large diameter is arranged at the center of the sprinkling plate 2 and the outer peripheral edge of the sprinkling plate 2. Since the water spray hole 3b having a small diameter is disposed in the water spray plate 2 and the shape of the water spray plate 2 is formed in a substantially conical plate shape, the water spray hole 3a having a large diameter is located at the tip of the water discharge direction and has a small diameter. The water spray hole 3b is located behind the water discharge direction. When hot water is supplied from the water supply pipe to the shower head 1 and the hot water flows so that the shower water D is ejected from the water spray holes 3 of the water spray plate 2, the water spray holes 3a having a larger diameter are ejected more than the water holes 3b having a smaller diameter. The flow of hot water flowing from the shower head 1 to the sprinkling plate 2 as a whole flows toward the sprinkling hole 3a having a large diameter as indicated by an arrow A in FIG. Since the large-diameter sprinkling hole 3a is disposed near the center of the sprinkling plate 2 in the water discharge direction, the flow of hot water near the side wall of the shower head 1 is in the water discharge direction as shown by the arrow B in FIG. A flow B toward the water spray hole 3a having a large diameter is formed along the inclined surface on the shower head side of the water spray plate 2 from which the center portion of the conical plate projects toward the front. Since the fine dust 5 contained in the hot water supplied to the shower head 1 is greatly influenced by the above-described hot water flows A and B, the fine dust 5 etc. has a large water spray hole. It is carried by the flows A and B toward 3a, and is ejected to the outside together with hot water from the large-diameter sprinkling hole 3a, so that clogging of the small-diameter sprinkling hole 3b is difficult to occur.
[0015]
Moreover, it is preferable that at least the water spray plate 2 is manufactured by resin molding, so that it can be easily formed in manufacturing and the cost can be reduced.
[0016]
【The invention's effect】
As described above, in the structure of the water spray portion of the shower head according to claim 1 of the present invention, the water spray plate is provided at the water outlet of the shower head, and the water spray holes are arranged in a ring on the water spray plate. A plurality of sprinkling hole rows are concentrically arranged, and the diameter of the sprinkling hole rows of the plurality of sprinkling hole rows is gradually reduced from the sprinkling hole row at the center toward the sprinkling hole row at the outer periphery. The shower diverted from the sprinkling holes of the plate is formed so that it gradually narrows from the central part of the shower water to the outer peripheral part. The shower diverted from the small-diameter sprinkling hole located at the periphery has a small flow rate, so that the splashing of hot water can be made small, and the shower diverted from the large-diameter sprinkling hole located in the center of the shower water. Shower shunt flow However, the splashed water of the boiled water that splashes outside is to block the shower shunt located at the outer periphery of the shower water from splashing outside. It is possible to greatly suppress the bounce of the.
[0017]
Further, dusting the inner surface of the water plate from the outer peripheral edge so it is tilted in the water discharge direction across the central portion, hot water, from a shower head to the nozzle plate so large nozzle holes of diameter is one flow for injecting hot water often In the flow channel, the flow that flows toward the large-diameter sprinkling hole is the main flow, and on the inner surface of the sprinkling plate, a large sprinkling hole is arranged from the outer periphery where a small sprinkling hole with a small flow rate is arranged. Since it protrudes and inclines in the direction of water discharge toward the center, the flow of hot water is formed along the inner surface of the water spray plate toward the water spray hole having a large diameter, and fine dust contained in the hot water is formed. Is greatly affected by the flow of hot water toward the large-diameter sprinkling holes, so that the trash is transported by the hot water flow and moves to the center of the sprinkling plate, and from the large-diameter sprinkling holes to the outside of the shower head. The trash will be ejected It is to prevent the clogging small nozzle holes of.
