Description

  The present invention relates to a shower head, and more particularly to a shower head that discharges hot water supplied from a large number of water spray holes.

  In a conventional shower head, a configuration is known in which a water spray plate having a plurality of water spray holes at the end of a water passage flowing in the shower head main body is fixed to the shower head main body. The shower head may stop water discharge after use and the shower head main body may be locked to the shower hook. . Then, there is a problem that air exchange occurs due to the intrusion of outside air from the water sprinkling hole, and hot water remaining in the shower head leaks from the water sprinkling hole to cause water dripping and drops the quality of the shower head. is there. In order to solve this problem, it is known that a water film can be easily formed on the net by inserting a mesh net on the upstream side of the water spray plate so that hot water remaining in the shower head does not flow out. (For example, refer to Patent Document 1).

  However, even when a mesh net is inserted inside the sprinkler plate, the shower head sprinkler holes and the inserted mesh are caused by vibrations when the shower hose moves after cleaning, after using the shower, or during reuse. There is a problem that the water film of hot water remaining between the mesh net is broken and the remaining hot water leaks out. In order to solve this problem, in order to make it easy to form a hot water film in the vicinity of the water spray hole, a method of reducing the diameter of the water spray hole in a tapered shape and improving the water stoppage is known (for example, patents). Reference 2).

Japanese Patent Laid-Open No. 2002-355581 JP-A-9-85132

  However, if the diameter of the water spray hole of the shower head is reduced, the flow rate must be secured when using with a constant water discharge amount. Will be used. In a shower in which the water discharge pressure is increased and the diameter of the sprinkling holes is reduced, the force per unit area increases, so that when the user discharges water to the water discharge target part, a force concentrated on the water discharge target part is applied. For this reason, there is a problem that the shower user is strongly stimulated, feels painful, feels uncomfortable, and impairs comfort when using the shower.

  An object of the present invention is to provide a shower head that does not deteriorate the comfort during use of the shower and further improves the water stoppage after use.

  In order to achieve the above object, a shower head according to the present invention is a shower head having a plurality of water spray holes at the tip of a water passage flowing in the shower head body, wherein the shower head is a water spray hole formed of the plurality of water spray holes. The plurality of sprinkling holes that have a plurality of groups and form the one sprinkling hole group are adjacent to the water flow discharged from the plurality of sprinkling holes that form the one sprinkling hole group And is formed so as to be a mixed water stream.

  By this structure, it becomes easy to form a water film by making the hole diameter of each watering hole small, and it can improve water-stopping. Furthermore, the water flow discharged from the sprinkling holes is merged in the vicinity of the discharged water, resulting in a mixed water flow that can be made thicker and comfortable even if the user does not feel pain when taking a shower. Can be improved.

  Further, in the shower head of the present invention, the plurality of water spray holes are formed in a water spray plate provided in the shower head, and the mixed water flow is a central axis obtained by drawing a perpendicular from the center of the water discharge surface of the water spray plate. On the other hand, it is formed so as to be discrete.

  With this configuration, since the mixed water flow is dispersed so as to be separated from the central axis of the water spray plate, that is, to spread outward with respect to the central axis, the mixed water flow has spread outward from the central axis of the water spray plate. It can be set as a shower head, and a user's comfort can be improved more.

  Furthermore, the present invention is characterized in that the interval between the plurality of water spray holes forming the one water spray hole group is narrower than the interval between the water spray hole groups.

  With this configuration, since the interval between the plurality of sprinkling holes is narrower than the interval between the sprinkling hole groups, the water flow discharged from each of the plurality of sprinkling holes forming one sprinkling hole group is the other sprinkling hole group. The water flow discharged from the sprinkling holes forming the water flow does not merge with each other, and the water flows discharged from the plurality of water sprinkling holes forming one sprinkling hole group are easily merged after the water discharge to make the mixed water flow easy. Can do. In addition, the space | interval of sprinkling holes here is not a location where the hot water of a sprinkling hole flows in, but is a space | interval of the center of the sprinkling hole of the outlet side finally discharged from a sprinkling hole, and between sprinkling groups. The distance is also the distance between the centers of the outlet-side sprinkling hole group finally discharged from the sprinkling holes.

  Furthermore, the present invention is characterized in that the plurality of water spray holes are non-circular.

  With this configuration, since the shape of the water spray hole is non-circular when the hole area of the non-circular water spray hole is equal to the circular hole area, the dimension of the short side that is the length facing through the axis of the water spray hole is true. It is shorter and narrower than the yen, making it easier to form a water film and improving the water stoppage.

  According to the present invention, it is easy to form a water film by reducing the diameter of each water sprinkling hole, and it is possible to improve the water stoppage. Furthermore, it is possible to improve the user's comfort without letting the user discharge the discharged water having a narrow flow by joining the water discharged from the water sprinkling holes in the vicinity of the discharge from the shower head. effective.

  Hereinafter, embodiments of the shower head of the present invention will be described with reference to the accompanying drawings. 1 and 2 are a longitudinal sectional view and an external view showing a shower head according to an embodiment of the present invention. As shown in FIG. 1 and FIG. 2, the shower head 1 according to the embodiment of the present invention allows hot water supplied from the faucet body (not shown) side to pass through a water passage that flows in the shower head 1. ing. On the downstream side of the shower head 1, a flange 2 that distributes the supplied hot water to the entire water discharge direction is disposed. A water spray plate 3 is provided downstream of the flange 2 to disperse and discharge hot water supplied from the flange 2. Here, the water spray plate 3 is provided with a plurality of water spray holes 5, and hot water is supplied to the user from the water spray holes 5. The water spray plate 3 includes a water spray hole group 4 formed by collecting a plurality of water spray holes 5, which will be described in detail later.

  Next, the water discharge mechanism by the water spray hole group 4 and the water spray holes 5 provided in the water spray plate 3 will be described in detail with reference to FIGS. FIG. 3 is a longitudinal sectional view showing a water discharge portion of the shower head in the first embodiment of the present invention, and FIGS. 4 and 5 are one watering hole provided in the shower head of the first embodiment of the present invention. FIG. 5 is an enlarged view showing the group 4 (A part of FIG. 2 and FIG. 3), FIG. 5 (a) is a cross-sectional view of the sprinkling hole group 4 seen from the BB cross section in FIG. 4, and FIG. 4 is a cross-sectional view of the sprinkling hole group 4 as seen from a CC cross section in FIG.

  The watering plate 3 in FIG. 3 of the present embodiment is provided with a plurality of watering holes 5 radially from the center of the watering plate 3. FIG. 4 is an enlarged view of the portion of FIG. 3A, and four sprinkling holes 5 are provided to form one sprinkling hole group 4.

  5A and 5B show a cross section through which water flows from the water spray hole 5 in the direction of water discharge. The water spray holes 5 are discharged from the center of the water spray plate 3 while being inclined in any direction with respect to the central axis that is perpendicular to the water spray plate. It heads toward the center of the formed water spray hole group 4. The water discharge angle 61, which is an inclined angle, is formed at 85 ° in both the BB cross section and the CC cross section.

  After the water flow 6 discharged from the sprinkling hole 5 is discharged, it joins with another water flow 6 provided in the same sprinkling hole group 4 and discharged from another sprinkling hole 5 in the vicinity of the discharged water. Yes. Thereby, the mixed water stream 7 is discharged. The number of the mixed water streams 7 is merged and discharged from the water streams 6 so as to coincide with the number of the sprinkling hole groups 4 formed from the sprinkling holes 5. Since the mixed water flow 7 comes out from one sprinkling hole group 4, the thickness of the water flow that pours on the user is larger than that of the unmixed water flow 6. Moreover, the vicinity here shows that the confluence | merging distance 62 which is the distance until the discharged water flow 6 merges is short, and is the vicinity of the watering board 3. FIG. For this reason, the form of water discharge that occurs when a small amount of water is discharged under low water pressure in the shower head 1 and falls as a mass of water through the water spray plate 3 is not included as a mixed stream line. .

  By comprising in this way, the water flow 6 does not pour into a shower user each independently independently, and the water flow 6 discharged from the sprinkling hole 5 joins, and pours into a user as the mixed water flow 7. Since the mixed water stream 7 is thicker than the water stream 6 and is discharged in a large amount, it is possible to suppress irritation when the user pours into the water discharge target and to improve the comfort of shower use.

  On the other hand, the total water flow area of the water spray holes 4 provided in the water spray hole group 4 is constant, and the water flow of the water holes 5 per water hole provided in the water spray hole group 4 is related to adjusting the water discharge pressure. As shown in FIG. 5, the hole diameter is as small as φ0.5 mm. For this reason, the surface tension of the hot water existing in the shower head 1 after using the shower is increased by reducing the diameter of the water passage hole per one water sprinkling hole 5, thereby improving the water stoppage of the shower head 1. it can.

  Here, in this embodiment, although the four water spray holes 5 are handled as one water spray hole group 4, it does not restrict | limit in particular to this. If the number of water spray holes 5 forming one water spray hole group 4 is a plurality of two or more, it is applied within a range in which there is no bias in the water discharge pressure compared to the central part and the outer peripheral part of the water spray plate 3. Can do.

  Further, in the present embodiment, the water discharge angle 61 from which the water flow 6 is discharged from the water spray hole 5 is 85 °, preferably 60 ° to 85 °, but is not particularly limited thereto. . It is desirable to form the water discharge angle 61 at an angle that allows the water discharge 6 to become the mixed water flow 7 before reaching the object. Further, even if the water discharge angle 61 is too small, hot water from the sprinkling holes collides vigorously and does not become the mixed water flow 7. Therefore, a certain angle or more is required for forming the water discharge angle.

  Further, in this embodiment, the diameter of the water spray hole 5 is set to φ0.5 mm from FIG. 5, and preferably φ0.1 to φ0.7 mm, but is not particularly limited thereto. Even if the discharged water stream 6 becomes the mixed water stream 7, it does not become too thin so that the user does not feel pain and irritation, and the water flow area increases and the water supply pressure in the shower head 1 decreases, It is desirable to form the diameter of the sprinkling holes to such an extent that the spouted water stream 6 is not so thick that the mixed water stream 7 cannot be created.

  And in this embodiment, the confluence distance 62 which is the distance until the water flow 6 spouted from the sprinkling hole 5 from FIG. 5 joins the water flow 6 in the vicinity spouted from the sprinkling hole 5 is 5 mm, preferably 3 Although it is set to 200 mm, it is not limited to this. It is desirable to form an angle at which water is discharged from the sprinkling holes at an angle at which the water flow 6 to be discharged can become a mixed water flow 7 before being bathed on the object.

  In addition, the arrangement of the watering holes 5 forming the watering hole group 4 is formed such that the watering holes 5 are plural. The sprinkling holes 5 and the sprinkling hole group 4 are provided on the sprinkling plate 3, but are provided so that the spacing between the sprinkling holes 5 forming the sprinkling hole group 4 is narrower than the spacing between the sprinkling hole groups 4. Yes.

  By this structure, since the space | interval of the water spray holes 5 which form the water spray hole group 4 is narrow, the water flow 6 discharged from one water spray hole becomes easy to merge with another water flow 6 after water discharge, and one mixing It becomes easy to become the water flow 7.

  Next, the shower head in 2nd Embodiment of this invention is demonstrated using FIG. 6 thru | or FIG. Explanations and symbols common to the other embodiments will be omitted.

  FIG. 6 shows the water spray plate 3 which is the water discharge portion of the shower head 1 in this embodiment of the present invention, and a cross section is taken so as to pass through the A portion of FIG. 2 and the central axis of the water spray plate 3. FIG. 7 is a longitudinal sectional view, and FIG. 7 is an enlarged view showing one sprinkling hole group 4 (part A in FIG. 2) provided in the shower head 1 of the present embodiment, and FIG. Sectional drawing of the water spray hole group 4 seen from the DD cross section in FIG. 7, (b) is sectional drawing of the water spray hole group 4 seen from the EE cross section in FIG. In FIG. 6 to FIG. 8, a description on which position of the water spray plate 3 the water spray hole 5 is provided and whether it is the center of the water spray plate or the outer periphery from the position of the water spray plate 3 and the water spray hole 5. I am doing.

  In this embodiment, the point which is different from 1st Embodiment exists in the angle which directs the water discharge of the water flow 6 and the mixed water flow 7 which come out of the water spray hole 5 from each other. The water spray holes 5 provided in the water spray plate 3 in FIG. 6 are provided to be inclined in the direction of the outer periphery with respect to the central axis 10 drawn perpendicularly from the center of the water discharge surface of the water spray plate 3. The inclination direction is directed in the direction of being separated from the central axis while being directed to the center of the water spray hole group 4 formed by each of the water spray holes 5. The water flow 6 and the mixed water flow 7 discharged from the water sprinkling holes 5 are directed in the direction of being dispersed from the central axis toward the outer peripheral side of the water spray plate 3. The water discharge surface of the water spray plate 3 here is a surface outside the water spray plate from which hot water is discharged from the water spray hole 5.

  8A and 8B show a cross section through which water flows from the water spray hole 5 in the direction of water discharge. The water discharge angle 61, which is an inclined angle, is formed at 85 degrees on the outer peripheral side in the DD cross section, 95 degrees on the outer peripheral side in the EE cross section, and 75 degrees on the central side.

  Further, in this embodiment, the water discharge angle 61 at which the water flow 6 is discharged from the sprinkling holes 5 from FIG. 8 is 85 degrees on the outer circumference side in the DD section, 95 degrees on the outer circumference side in the EE section, and the center side. 75 degrees, preferably 60 degrees to 85 degrees on the center side and 85 degrees to 110 degrees on the outer peripheral side, but is not particularly limited thereto. It is desirable to form the water discharge angle 61 in such an angle that the discharged water flow 6 can become the mixed water flow 7 before reaching the object and in a direction in which the mixed water flow 7 is separated from the central axis of the water spray plate 3. Further, even if the water discharge angle 61 is too small, hot water from the sprinkling holes collides vigorously and does not become the mixed water flow 7. Therefore, a certain angle or more is required for forming the water discharge angle.

  According to one aspect of the present embodiment, as shown in FIG. 6, the water spray holes 5 are provided so that the mixed water flow is directed from the central axis of the water spray plate 3 to the outer peripheral side, thereby widening. With this configuration, the mixed water flow 7 coming out of the shower head 1 can be widened, and a shower head that covers a large water discharge area can be provided.

  Next, the shower head in 3rd Embodiment of this invention is demonstrated using FIG. 9, FIG. Explanations and symbols common to the first and second embodiments are omitted.

  In this embodiment, a different point from other embodiment is that the shape of the watering hole 5 is different. What was shown in FIG. 9 is the shape of the watering hole 5 in this embodiment, and is the enlarged view of the A section in FIG.

  The shape of the water spray hole 5 in this embodiment is an ellipse as shown in FIG. 10A is a cross-sectional view of the sprinkling hole group 4 in the FF cross section in FIG. 9, and FIG. 10B is a cross-sectional view of the sprinkling hole group 4 in the GG cross section in FIG. Is an ellipse having a long side of 0.625 mm and a short side of 0.4 mm, and is non-circular.

  By adopting a non-circular shape, for example, when the hole area of the sprinkling hole 5 is equal to a circular shape and a non-circular shape, the dimension of the short side that is the shortest in the length facing through the axis of the sprinkling hole is larger than that of a perfect circle Since it becomes shorter and narrows, it is possible to further increase the surface tension and to further improve the water stoppage.

  In the present embodiment, the shape of the water spray hole 5 is an ellipse. However, other than the ellipse, a non-circular shape such as a polygon or a sector is also conceivable. Since the length of the periphery of the water spray hole 5 is shorter than that of the circular water spray hole 5 having the same hole area, the dimension of the short side is shortened, the surface tension can be increased, and the water stoppage can be further improved.

  The present invention can be used in any environment where a shower is used, such as an embodiment in which a bathroom, a wash basin, and other faucets are coupled and a shower head can be coupled.
