Description

The present invention relates to a shower head used for hair washing or the like, and more particularly, to a shower head in which shower water is uniformly sprinkled from a water spray hole of a water spray plate and can be prevented from bouncing off at the shower water landing site.

  Shower water is used for various kinds of washing such as hair washing, body washing and dish washing. Shower water is sprayed toward the object to be cleaned from a number of water spray holes formed in a water spray plate of a shower head to which water or hot water supplied through a shower hose is connected.

  When shower water sprayed from the shower head collides with a landing spot, there arises a disadvantage that washing water containing bubbles and dirt splashes and wets the surrounding area. Therefore, various shower heads have been proposed in order to prevent splashing of shower water.

  In Patent Document 1, in order to prevent shower water spouted from the water spray plate of the shower head from splashing back at the shower water landing position, a water spray plate is provided at the water outlet of the shower head, and a water spray hole is provided in the water spray plate. Multiple sprinkling hole rows formed in a ring are arranged concentrically, and the diameter of the sprinkling holes of the plurality of sprinkling hole rows is changed from the sprinkling hole row at the center to the sprinkling hole row at the outer periphery. A shower head formed gradually smaller is disclosed. In this shower head, the shower diverted from the small-diameter sprinkling hole located at the outer peripheral edge of the shower water is formed into a thin one with a small flow rate, and therefore does not rebound so much. Also, since the shower diversion is located on the outer periphery of the shower water, the boiled water of the shower diversion in the center of the shower water interferes with the shower diversion and wraps so that it does not fly outside the shower water. In this way, the rebound of shower water is reduced.

Further, in Patent Document 2, in order to suppress the splashing of water, a large number of water spray holes are concentrated and opened in the center to create a straight jet, and a large number of water spray holes are arranged in an annular shape around this. An annular sprinkling hole array is provided to create a curtain-like water flow, and the spray water sprayed from the annular sprinkling hole array is gathered toward a point on the center line at a predetermined distance in front of the sprinkling plate. A shower head using a watering plate that prevents splashing of water is disclosed.

  The shower head of Patent Document 1 is formed so that the diameter of the water spray holes in the water spray hole array gradually decreases from the water spray hole array in the central part toward the water spray hole array in the outer peripheral part. Not only water is not uniformly sprayed, but not only is unevenness per water, but also the shower diverted from the water spray hole having a diameter located at the outer peripheral edge has a drawback that rebounding occurs although the amount of water is small.

  Further, in Patent Document 2, although the curtain-like water flow ejected from the annular sprinkling hole row is gathered toward the central straight jet, the side on which water is introduced into the head and the opposite side thereof However, since the amount of water discharged from the side where it is naturally introduced is reduced, there is a problem in that a uniform curtain-like water flow cannot be produced and water splashes from the gap between the curtains.

  Therefore, the present invention provides a shower head that can suppress splashing of shower water by providing a uniform and uniform water curtain per shower water.

The invention of claim 1 of the present application is a shower head in which a water spray plate having water spray holes for spraying shower water is attached to a water outlet of an internal space into which water is introduced, and is introduced into an inner wall of the internal space. A water-dispersing projection having a convex curved surface that is dispersed when water hits the inner wall on the extension line of water is formed, and the watering plate has a plurality of concentric annular watering holes formed on the outermost outer periphery. The annular sprinkling hole is a shower head characterized in that the shower water to be sprinkled is inclined toward the vertical line side of the sprinkling plate at an angle that does not interfere with the shower water inside the shower water at the landing point.

The invention of claim 2 of the present application is the shower head according to claim 1, wherein the shape of the convex portion is a hemispherical shape or a projection similar to a hemispherical shape.

In the present invention, water is evenly distributed in the internal space 6 by providing the water dispersion protrusions on the extended line of water introduced into the inner surface of the shower head, and the same water pressure is applied to all the water spray holes provided in the water spray plate. As a result, an equal amount of water is discharged from all the water sprinkling holes, so that a uniform curtain-like water flow can be formed on the outer periphery, and in addition to preventing water splash, unevenness per water can be eliminated.

Moreover, the shower head of this invention prevents the shower water discharged from the water spray hole arrange | positioned in the outer periphery of a water spray plate from acting as a curtain, and the water inside a curtain splashes outside. In this way, it is possible to prevent makeup drop off due to water splashing and fouling around the hair washing table, which are problems in conventional showers, particularly in hair washing in a beauty salon or the like.

The shower head of this invention is shown, (a) is explanatory drawing which shows arrangement | positioning of a water spray hole and protrusion, (b) is sectional drawing which shows the cross section of a shower head, and the state of water spray. The another Example of the processus | protrusion of the shower head of this invention is shown, (a) is explanatory drawing which shows arrangement | positioning of processus | protrusion, (b) is sectional drawing of the cross section of processus | protrusion.

As shown in FIG. 1, the shower head of the present invention is provided with water-dispersing projections 5 a on the inner wall of the inner space 6 for evenly dispersing water on the extension line of the water to be introduced. The water flowing into the interior space 6 of the shower head strikes the water dispersion projection 5a and is evenly dispersed in the interior space 6, and the same amount of water is discharged from all of the water spray holes 2 and 3 of the water spray plate 1 so Unevenness is eliminated.

The water-dispersing protrusions 5a form a convex curved surface on which the introduced water hits and uniformly distribute the surface. The shape of the protrusion 5a is made to be a hemisphere shown in FIG. 1 or a shape similar to the hemisphere shown in FIG. The diameter of the protrusion 5a is approximately the same as the diameter of the water channel to be introduced, and water can be sufficiently dispersed.

A water spray plate 1 is attached to the water outlet of the shower head 5. A plurality of concentric annular sprinkling holes 2, 3 are formed in the sprinkling plate 1, an annular outer annular sprinkling hole 2 is formed on the outermost periphery, and concentric inner ring is formed in a plurality of rows inside the annular sprinkling hole 2. Sprinkling holes 3 are formed. The outer annular sprinkling holes 2 have a diameter of 0.3 to 0.4 mm, and the interval between adjacent sprinkling holes 2 is 1 to 1.2 mm so that curtain-shaped shower water is formed. The diameter of the inner watering hole 3 is equal to or slightly larger than that of the watering hole 2, but the interval between the watering holes is not particularly defined and is arbitrary. In the present invention, the number of water spray holes is set to 120 to 180, and the total opening area of the water spray holes is set to ²⁰ to 25 mm ² , so that unevenness per water is eliminated and water splash is suppressed. it can.

  The outer annular sprinkling hole 2 is inclined toward the vertical line side in order to discharge the shower water 2a toward the vertical line at the center of the sprinkling plate 5 so that the shower water 2a hits the cleaning object 4 and rebounds toward the center. Let The angle of the water spray hole 2 is set to an angle that does not collide with the inner shower water 3a before hitting the cleaning object 4 because it cannot be prevented from bouncing back when hitting the inner shower water 3a before hitting the cleaning object 4. When washing with shower water on the object to be washed, the distance between the shower head and the object to be washed is close to the case of washing hair, but it is rare to exceed 1.5 m even when washing away by washing the car, etc. The angle of the outer annular sprinkling hole 2 is such that the shower water to be ejected reaches a distance of about 1.5 m from the shower head to the vertical line at the center of the sprinkling plate 5, and the outer annular sprinkling water is in front of the object to be cleaned. The curtain-like shower water in the hole 2 is prevented from interfering with the inner shower water. Therefore, the inclination angle toward the center side is preferably 0.7 to 6 degrees.
