Detailed Description
Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiment.
(embodiment mode 1)
Fig. 1 is a schematic perspective view of a shower device 2 according to embodiment 1.
The shower apparatus 2 shown in fig. 1 is a shower apparatus for a bathroom used in a bathroom. The shower device 2 shown in fig. 1 is particularly a top-spray type shower device fixedly attached to a ceiling 8 of a bathroom. As shown in fig. 1, the shower device 2 includes a water spray plate 4.
The water spray plate 4 is a plate-like member for spraying water. The water spray plate 4 has a water spray surface 5. The water spray surface 5 is a surface on one side of the water spray plate 4 and is provided to face downward. The "water-jet surface" may also be referred to as "water-outlet surface", etc.
As shown in fig. 1, a plurality of water jetting holes 10 are formed in the water jetting surface 5. The water jetting holes 10 are through holes penetrating the water jetting plate 4 in the thickness direction, and extend from the water jetting surface 5, which is the front surface (outflow surface) of the water jetting plate 4, to the back surface (inflow surface). The plurality of water ejection holes 10 shown in fig. 1 are arranged in a circumferential shape.
In the shower device 2 according to embodiment 1, the structure of the water jetting hole 10 is designed elaborately. Specifically, the description will be given with reference to fig. 2 to 5.
Fig. 2 is a schematic plan view of the water spray plate 4. Fig. 2 schematically shows a plurality of water discharge holes 10, and the number of water discharge holes 10 is also simplified.
As shown in fig. 2, when the water discharge surface 5 is viewed in plan, the plurality of water discharge holes 10 are arranged at intervals from each other, and are arranged in a circumferential shape so as to overlap with the circumference 9 as an imaginary line. The center 11 of the circumference 9 is the center of the water emitting surface 5.
The spout holes 10 form a downstream opening 12 as an opening of a downstream end and an upstream opening 14 as an opening of an upstream end, respectively. The downstream opening 12 is opened in the water discharge surface 5, and the upstream opening 14 is opened in the rear surface of the water discharge plate 4 facing the water discharge surface 5. Water passing through the water jet 10 flows from the upstream opening 14 toward the downstream opening 12 (reference numeral 20). In embodiment 1, the downstream opening 12 and the upstream opening 14 are circular openings having substantially the same radius.
When the water discharge surface 5 is viewed in plan as shown in fig. 2, the downstream opening 12 and the upstream opening 14 of each water discharge hole 10 are arranged offset from each other. Specifically, the description will be given with reference to fig. 3 and 4.
Fig. 3 is an enlarged view of a portion of fig. 2, showing 1 water jet hole 10. Fig. 4 is a longitudinal sectional view of the spout 10 taken along line a-a of fig. 2.
As shown in fig. 3 and 4, the opening center 16 is located at the center of the downstream opening 12, and the opening center 18 is located at the center of the upstream opening 14. In embodiment 1, the opening center 16 of the downstream opening 12 is set to overlap with the circumference 9. As shown in fig. 3 and 4, the downstream opening 12 and the upstream opening 14 are arranged offset by offsetting the opening centers 16 and 18 in the plane direction F of the water jet plate 4.
As shown in fig. 4, the water spout 10 according to embodiment 1 is formed by etching a plate-like member from both sides. The inner circumferential surface of the sprinkler plate 4 forming the sprinkler hole 10 has a 1 st bent portion 22 and a 2 nd bent portion 24. The 1 st bent portion 22 is formed by etching the water spray plate 4 from the water spray surface 5. The 2 nd bent portion 24 is formed by etching the water spray plate 4 from the back surface 21.
Here, a straight line connecting the opening center 16 and the opening center 18 is assumed as a center line 20. The centerline 20 is substantially aligned with the direction of travel of the water in the spout 10. As described above, since the opening centers 16 and 18 are offset in the plane direction F of the water spray plate 4, the center line 20 extends so as to be inclined with respect to the thickness direction T (fig. 4) of the water spray plate 4.
Returning to fig. 3, the direction in which the center line 20 extends when viewed in plan with respect to the water jet surface 5 has an inclination component P1 with respect to the normal direction P of the circumference 9, and also has an inclination component Q1 with respect to the tangential direction Q of the circumference 9. In particular, by having the inclination component P1 with respect to the normal direction P, a different form of shower water from the normal shower water can be realized. Specifically, the description will be given with reference to fig. 5.
Fig. 5 is a diagram showing an example of the form of the shower outlet of the shower device 2 according to embodiment 1. As shown in fig. 5, a film is generated in which the shower flows downward from each of the plurality of water ejection holes 10 while swirling in the circumferential direction R.
In embodiment 1, as shown in fig. 3 in particular, the inclination component P1 of the center line 20 with respect to the normal direction P of the circumference 9 is set to a direction toward the circumferential direction R1, and as shown in fig. 2, the inclination component is set to the same circumferential direction R1 in all the water jet holes 10. This makes it possible to align the direction in which the water discharged from the spout hole 10 swirls with the circumferential direction R1, and to generate a spiral flow as shown in fig. 5, thereby realizing shower water having a good appearance. In embodiment 1, the case where the inclination component P1 of the center line 20 is unified in the circumferential direction R1 has been described, but appropriate modifications such as changing to the circumferential direction R2 in the direction opposite to the circumferential direction R1 may be made.
As for the inclination component Q1 of the center line 20, the direction in which the center line 20 extends from the upstream side to the downstream side as shown in fig. 3 is set to a direction farther from the center 11 of the circumference 9 than the tangential direction Q of the circumference 9. As shown in fig. 2, the inclination directions are set to be the same for all the water discharge holes 10. This can make the direction uniform so that the water discharged from the water discharge hole 10 moves in a direction away from the center 11 of the circumference 9, and can generate a flow spreading outward as it moves downward as shown in fig. 5. As a result, a spiral flow can be generated which spreads outward from the spout hole 10 and flows downward while revolving in the circumferential direction R, and shower water having a good appearance can be realized.
The angle of the inclination component P1 shown in fig. 3 may be set to, for example, 5 degrees or more and 175 degrees or less. This can generate a flow at an appropriate inclination angle.
The angle α formed by the center line 20 and the vertical direction 23 shown in fig. 4 may be set to, for example, 5 degrees or more and 45 degrees or less. This can generate a flow at an appropriate inclination angle.
In addition, the angle β formed by the center lines 20 of the adjacent 2 water ejection holes 10 among the plurality of water ejection holes 10 shown in fig. 2 may be set to 0.15 degrees or more and 175 degrees or less, for example. Thus, the interval between the water discharge holes 10 can be set appropriately. At the same time, the water ejected from the water ejection holes 10 can be prevented from merging immediately, a film of shower can be formed as shown in fig. 5, and shower water having good appearance can be realized.
Next, fig. 6 shows a structure of a comparative example. Fig. 6 is a plan view schematically showing a water spray plate 100 of a comparative example.
As shown in fig. 6, a plurality of water jetting holes 104 are formed in the water jetting surface 102 of the water jetting plate 100. The plurality of water jetting holes 104 are arranged in a circumferential shape and are arranged on a circumference 107 with respect to the center 105 of the water jetting surface 102.
The blowholes 104 are formed with downstream openings 106 and upstream openings 108, respectively. A straight line connecting an opening center 109 of the downstream opening 106 and an opening center 111 of the upstream opening 108 is defined as a center line 110. As shown in fig. 6, when the water discharge surface 102 is viewed in plan, the center line 110 of the water discharge hole 104 coincides with the normal direction of the circumference 107 of the water discharge hole 104. That is, the direction in which the center line 110 extends in plan view does not have an inclination component with respect to the normal direction of the circumference 107. With this configuration, the water ejected from the plurality of water ejection holes 104 travels downward without being swirled in the circumferential direction S while spreading outward away from the center 105.
In contrast, according to the shower apparatus 2 of embodiment 1, the center line 20 is provided with the inclination component P1 with respect to the normal direction P of the circumference 9, so that the swirl component in the circumferential direction R can be generated, and the form of the shower water can be realized which is different from the form of the normal shower water.
As described above, the shower apparatus 2 according to embodiment 1 is a shower apparatus including the water spray plate 4, and the plurality of water spray holes 10 penetrating the water spray plate 4 in the thickness direction T are arranged in a circumferential shape at intervals on the water spray surface 5 of the water spray plate 4. In such a configuration, when the water discharge surface 5 is viewed in plan, the direction in which the center line 20 connecting the opening center 18 at the upstream end and the opening center 16 at the downstream end of each of the plurality of water discharge holes 10 extends includes an inclination component P1 with respect to the normal direction P of the circumference 9 in each water discharge hole 10. With this configuration, a form of the shower water different from a form of the normal shower water can be realized.
(embodiment mode 2)
A shower apparatus according to embodiment 2 of the present invention will be described. In embodiment 2, the differences from embodiment 1 will be mainly described, and descriptions overlapping with embodiment 1 will be omitted.
While the plurality of water jetting holes 10 are arranged in 1 circle in embodiment 1, embodiment 2 differs in that a plurality of water jetting holes other than the plurality of water jetting holes 10 are formed in another circle.
Fig. 7 is a perspective view of a shower device 70 according to embodiment 2. The shower device 70 shown in fig. 7 includes a water spray plate 72, and a group of water spray holes 76 is formed on a water spray surface 74 of the water spray plate 72 in addition to the group of the plurality of water spray holes 10. When the water discharge surface 74 is viewed in plan, the plurality of water discharge holes 76 and the 1 st water discharge hole 10 are concentric and arranged circumferentially at intervals. The plurality of blowholes 10 is the 1 st blowhole and the plurality of blowholes 76 is the 2 nd blowhole. In embodiment 2, the 2 nd spout hole 76 is disposed inside the 1 st spout hole 10. With this configuration, by discharging water from the water discharge holes 10 and 76, a double-shower film can be formed, and a shower discharge mode different from the usual mode can be realized.
In the shower apparatus 70 shown in fig. 7, the inclination angle of the 2 nd water jetting hole 76 is also set in the same manner as the inclination angle of the 1 st water jetting hole 10 described in embodiment 1. Specifically, when the spout surface 74 is viewed in plan, the direction in which the center line connecting the opening center of the upstream end and the opening center of the downstream end of each of the 2 nd spout holes 76 extends includes an inclination component with respect to the normal direction of the circumference in each of the 2 nd spout holes 76. With this configuration, not only the plurality of water jetting holes 10 but also the plurality of water jetting holes 76 can generate a spiral flow, and other shower patterns can be realized.
The present invention is not limited to the above embodiments, and can be implemented in various other embodiments. For example, in embodiment 1, a description has been given of a case where the watering hole 10 is formed by etching and the watering hole 10 having the bent portions 22 and 24 as shown in fig. 4 is provided, but the present invention is not limited to this case. The water jetting holes may be formed by any method other than etching, and for example, the water jetting holes having the shapes shown in fig. 8A to 8D may be formed.
In the water spray plate 30 shown in fig. 8A, the inner peripheral surface of the water spray plate 30 forming the water spray holes 32 has a linear portion 34 inclined linearly. A center line 36 as a straight line connecting the opening center of the downstream opening 32A and the opening center of the upstream opening 32B of the spout hole 32 extends in a direction inclined with respect to the vertical direction. The water ejection hole 32 having such a shape can be formed by, for example, machining by 5-axis machining, laser machining, or the like.
The water spray plate 40 shown in fig. 8B is formed by laminating two plate members 42 and 44. The plate member 42 is formed with an opening 46 and the plate member 44 is formed with an opening 48. The 1 water jet hole 45 is formed by the opening 46 and the opening 48. The openings 46 and 48 are arranged offset in the surface direction G of the water spray plate 40. A center line 49, which is a straight line connecting the opening center at the upstream end of the opening 46 and the opening center at the downstream end of the opening 48, extends in a direction inclined with respect to the vertical direction. The water jetting holes 45 having such a shape can be formed by, for example, press bonding of the plate members 42, 44.
In the sprinkler plate 50 shown in fig. 8C, the inner circumferential surface of the sprinkler plate 50 forming the sprinkler hole 52 has the 1 st linear portion 54 and the 2 nd linear portion 56. The 1 st linear portion 54 extends in the thickness direction X of the water spray plate 50, and the 2 nd linear portion 56 extends in a direction inclined with respect to the thickness direction X of the water spray plate 50. A center line 58, which is a straight line connecting the opening center of the downstream opening 52A and the opening center of the upstream opening 52B of the spout hole 52, extends in a direction inclined with respect to the vertical direction. The water jetting hole 52 having such a shape can be formed by press working using a punch, for example.
In the water spray plate 60 shown in fig. 8D, the inner peripheral surface of the water spray plate 60 forming the water spray holes 62 has linear portions 64 and 66 having asymmetrical cross-sectional shapes. The linear portion 64 extends along the Y direction, which is the thickness direction of the water spray plate 60, and the linear portion 66 extends in a direction inclined with respect to the Y direction. A center line 68 as a straight line connecting the opening center of the downstream opening 62A and the opening center of the upstream opening 62B of the spout hole 62 extends in a direction inclined with respect to the vertical direction. The water jetting holes 62 having such a shape can be formed by, for example, resin molding.
In the blowholes 32, 45, 52, 62 shown in fig. 8A to 8D, the same flow as that of the water shown in fig. 5 is generated by designing the center lines 36, 49, 58, 68 so as to have an inclination component P1 with respect to the normal direction P of the circumference 9 as shown in fig. 3.
In embodiment 1, the description has been given of the case where the direction in which the center line 20 of each water discharge hole 10 extends from the upstream side to the downstream side is directed to the direction farther from the center 11 of the circumference 9 than the tangential direction Q of the circumference 9 in each water discharge hole 10 as shown in fig. 3, but the present invention is not limited to this case. For example, when the water discharge surface 5 is viewed in plan, the direction in which the center line 20 of each water discharge hole 10 extends from the upstream side to the downstream side may be directed closer to the center 11 of the circumference 9 than the tangential direction Q of the circumference 9 in each water discharge hole 10. In this case, a sprayed film can be formed so as to be narrowed inward from the plurality of water ejection holes 10. Alternatively, the direction in which the center line 20 of each water discharge hole 10 extends may be aligned with the tangential direction Q of the circumference 9 of each water discharge hole 10 when the water discharge surface 5 is viewed in a plan view. In this case, the inclination angle of the spout 10 can be set with reference to the tangential direction Q of the circumference 9, and the design becomes easy.
In embodiment 1, the description has been given of the case where the angle of the inclination component P1, the angle of the inclination component Q1, and the angle α shown in fig. 4 are the same value for all the water jet holes 10, but the present invention is not limited to this case. The angles may be set to different values for each water jetting hole 10.
In embodiment 2, the case where two water discharge hole groups of the plurality of water discharge holes 10 and the plurality of water discharge holes 76 are provided has been described, but the present invention is not limited to this case, and another water discharge hole group may be provided. That is, a film having a weight of 3 or more may be formed by spraying. An example of a structure for forming a 3-fold shower film is described in embodiment 3 below.
In embodiments 1 and 2, the case where the shower device 2 is a top-spray type shower device fixed to the ceiling 8 of a bathroom has been described, but the present invention is not limited to this case. For example, any shower device such as a hand-held shower device used by a user holding the shower device may be used.
The above modification can be similarly applied to embodiment 3 below.
(embodiment mode 3)
A water spray plate and a shower apparatus including the same according to embodiment 3 of the present invention will be described. In embodiment 3, differences from embodiments 1 and 2 will be mainly described, and descriptions overlapping with embodiments 1 and 2 will be omitted.
The embodiment 1 is different in that the groups of the water discharge holes 10 are arranged in a circumferential shape, the embodiment 2 is different in that the groups of the water discharge holes 10 and the groups of the water discharge holes 76 are arranged in a circumferential shape, and the embodiment 3 is different in that the groups of the 3 water discharge holes are arranged in a circumferential shape.
Fig. 9 is a plan view of the shower device 80 according to embodiment 3. The shower apparatus 80 shown in fig. 9 includes a water spray plate 84, and 3 sets of through- hole groups 81, 82, and 83 are formed on a water spray surface 85 of the water spray plate 84. The "through-hole" may also be referred to as a "water jet hole". The shower device 80 shown in fig. 9 is a shower device used as a faucet in a toilet, a kitchen, or the like. When the water spray plate 84 is viewed from the surface opposite to fig. 9, a group of through holes having the same pattern and position as those in fig. 9 may be formed.
The 1 st through hole group 81 is composed of a plurality of through holes arranged in a circumferential shape at the outermost side, the 2 nd through hole group 82 is composed of a plurality of through holes arranged in a circumferential shape at the center, and the 3 rd through hole group 83 is composed of a plurality of through holes arranged in a circumferential shape at the innermost side. The 2 nd through hole group 82 is disposed inside the 1 st through hole group 81, and the 3 rd through hole group 83 is disposed inside the 2 nd through hole group 82.
In embodiment 3, the number of through holes constituting the 1 st, 2 nd and 3 rd through hole groups 81, 82 and 83 is the same. As shown in fig. 9, the through holes of the 1 st, 2 nd, and 3 rd through hole groups 81, 82, and 83 are arranged in a row along the radial direction H of the water ejection surface 85.
Fig. 10 shows an enlarged view of a portion I of fig. 9.
As shown in fig. 10, the 1 st through hole (1 st spout hole) 81J constituting the 1 st through hole group 81 is arranged on the circumference 92, and forms a downstream opening 86A as an opening at a downstream end and an upstream opening 86B as an opening at an upstream end. The downstream opening 86A opens at the water discharge surface 85, and the upstream opening 86B opens at the rear surface 95 (fig. 11A to 11C) of the water discharge plate 84 facing the water discharge surface 85. The water passing through the 1 st through hole 81J flows in the discharge direction 87 from the upstream opening 86B toward the downstream opening 86A. The ejection direction 87 substantially coincides with a center line connecting the opening center of the upstream opening 86B and the opening center of the downstream opening 86A.
Similarly, the 2 nd through hole (2 nd spout hole) 82J constituting the 2 nd through hole group 82 is arranged on the circumference 93, and forms a downstream opening 88A as an opening of a downstream end and an upstream opening 88B as an opening of an upstream end. The water passing through the 2 nd through hole 82J flows in the ejection direction 89 from the upstream opening 88B toward the downstream opening 88A. The ejection direction 89 substantially coincides with a center line connecting the opening center of the upstream opening 88B and the opening center of the downstream opening 88A. Similarly, the 3 rd through hole (3 rd spout hole) 83J constituting the 3 rd through hole group 83 is arranged on the circumference 94, and forms a downstream opening 90A as an opening of the downstream end and an upstream opening 90B as an opening of the upstream end. The water passing through the 3 rd through hole 83J flows in the discharge direction 91 from the upstream opening 90B toward the downstream opening 90A. The ejection direction 91 is substantially coincident with a center line connecting the opening center of the upstream opening 90B and the opening center of the downstream opening 90A.
Similarly to embodiments 1 and 2, the ejection directions 87, 89, and 91 of the 1 st through hole 81J, the 2 nd through hole 82J, and the 3 rd through hole 83J include the inclination components α 1, α 2, and α 3 with respect to the normal directions U1, U2, and U3 of the respective circles 92, 93, and 94. As a result, water is discharged in a "spiral shape" from the 1 st, 2 nd, and 3 rd through- hole groups 81, 82, and 83, respectively, and a triple spiral water discharge mode can be realized.
In embodiment 3, the ejection directions 87, 89, and 91 of the 1 st through hole 81J, the 2 nd through hole 82J, and the 3 rd through hole 83J are directed toward the center side with respect to the tangential directions of the circumferences 92, 93, and 94. That is, the water discharged from the 1 st through hole 81J, the 2 nd through hole 82J, and the 3 rd through hole 83J is discharged toward the center of the water discharge plate 85.
Further, in embodiment 3, the through holes 81J, 82J, 83J are shaped so that the inclination components α 1, α 2, α 3 with respect to the normal directions U1, U2, U3 are in a relationship of α 1> α 2> α 3. That is, the inclination component α 1 of the ejection direction 87 with respect to the normal direction U1 is larger than the inclination component α 2 of the ejection direction 89 with respect to the normal direction U2, and the inclination component α 2 of the ejection direction 89 with respect to the normal direction U2 is larger than the inclination component α 3 of the ejection direction 91 with respect to the normal direction U3.
By setting the inclination components α 1, α 2, and α 3, the through holes 81J, 82J, and 83J located on the outer side have a component that advances in the rotational direction along the circumference as the through holes become larger, and water drops toward the center of the downward water spray plate 84. The water ejected from the 1 st, 2 nd, and 3 rd through- hole groups 81, 82, and 83 converges once on the center side and then diverges in a direction away from the center. Such a triple helix shape of the outlet water can be realized.
Next, fig. 11A, 11B, and 11C show vertical sectional views of the 1 st through hole 81J, the 2 nd through hole 82J, and the 3 rd through hole 83J. Fig. 11A is a K-K view of the 1 st through hole 81J in fig. 10, fig. 11B is an L-L view of the 2 nd through hole 82J, and fig. 11C is an M-M view of the 3 rd through hole 83J.
As shown in fig. 11A, the ejection direction 87 of the water from the 1 st through hole 81J has an inclination component β 1 with respect to the thickness direction T of the water spray plate 84. Similarly, as shown in fig. 11B, the discharge direction 89 of the water from the 2 nd through hole 82J has an inclination component β 2 with respect to the thickness direction T, and as shown in fig. 11C, the discharge direction 91 of the water from the 3 rd through hole 83J has an inclination component β 3 with respect to the thickness direction T. The inclination components β 1, β 2, β 3 are all components toward the center side of the water ejection surface 85 as shown in fig. 10.
In embodiment 3, the through holes 81J, 82J, and 83J are particularly shaped so that the inclination components β 1, β 2, and β 3 with respect to the thickness direction T are in a relationship of β 1> β 2> β 3. That is, the inclination component β 1 of the ejection direction 87 is larger than the inclination component β 2 of the ejection direction 89, and the inclination component β 2 of the ejection direction 89 is larger than the inclination component β 3 of the ejection direction 91.
By setting the inclination components β 1, β 2, and β 3 as described above, the through holes 81J, 82J, and 83J located on the outer side have a component that travels in the direction parallel to the water discharge surface 85 as the size of the through holes increases, and water falls toward the center of the downward water discharge plate 84. When the water discharged from each of the 1 st, 2 nd, and 3 rd through- hole groups 81, 82, and 83 forms a spiral flow, the through-holes located on the outer side discharge water with a stronger rotational component, and the water flows toward the center of the water discharge plate 84, converges on the center, and then diverges so as to spread outward. Such a triple helix shape of the outlet water can be realized.
The structure of the through holes 81J, 82J, and 83J described above can form a triple helical flow as shown in fig. 12. As shown in fig. 12, among the through hole groups 81, 82, and 83, the more outward the through hole group is, the stronger the component toward the lateral direction, which is the direction parallel to the water ejection surface 85. The water ejected from the 1 st through hole group 81 has a stronger component in the lateral direction than the water ejected from the 2 nd through hole group 82, and the water ejected from the 2 nd through hole group 82 has a stronger component in the lateral direction than the water ejected from the 3 rd through hole group 83. Since the water ejected from the through hole groups 81, 82, and 83 all fall toward the center, the water once converges in the converging region 96 and then diverges from the diverging region 98 in a direction away from the center. When water is dispersed in the dispersing area 98, the groups of through holes 81, 82, and 83 located on the outer side are dispersed in a direction away from the center.
According to such a discharge form, not only aesthetic, but also part of the water sprayed with a large contact area as in the convergence region 96 and part of the water sprayed with a small contact area as in the divergence region 98 can be used separately according to the purpose of use. For example, when a finger tip or a fine stain is washed, the object can be washed without waste at a portion where water is concentrated by placing the object in the constricted region 96. On the other hand, if the object is placed in the divergent region 98, a large region such as a palm or an arm can be washed quickly. In addition, when the shower apparatus 80 is provided in a large water tank, the large water tank can be efficiently flushed by using the diverging region 98.
Further, if water is discharged into the circular tub in the shower discharge form of embodiment 3, a vortex flow can be generated in the tub, and handkerchiefs and the like can be efficiently washed in the tub. In addition, when a lotion is added, the lotion can be mixed well.
Further, according to the shower outlet form of embodiment 3, since the spiral flow is triple, wind can be generated around the shower outlet form. For example, when the shower apparatus is used as a shower device in a bathroom, the user can feel the wind.
In a general faucet capable of switching between a straight discharge and a shower discharge, water does not flow into a space right in the middle corresponding to the center of the water spray plate when the shower discharge is performed. In contrast, with the discharge form of embodiment 3 shown in fig. 12, water can be caused to flow into the space in the middle, and a discharge form different from the usual one can be realized.
As described above, the water spray plate 84 according to embodiment 3 is a water spray plate in which a plurality of through hole groups 81, 82, and 83 are formed on the water spray surface 85. The water spray plate 84 is formed with: a 1 st through-hole group 81 including a plurality of through-holes 81J arranged on a circumference 92; and a 2 nd through hole group 82 which is arranged inside the 1 st through hole group 81 and is composed of a plurality of through holes 82J arranged on the circumference 93. In the 1 st through hole group 81 and the 2 nd through hole group 82, the water discharge directions 87 and 89 after passing through the through holes 81J and 82J include inclination components α 1 and α 2 with respect to the normal directions U1 and U2 of the circumferences 92 and 93 of the through holes 81J and 82J when viewed in a plan view on the water discharge surface 85.
With such a configuration, a spiral shower film can be formed in two or more layers, and the same effects as those of the shower plate 72 and the shower device 70 according to embodiment 2 can be obtained.
Further, according to the water spray plate 84 of embodiment 3, in the 1 st through hole group 81 and the 2 nd through hole group 82, the water discharge directions 87 and 89 are inclined toward the center sides of the circumferences 92 and 93 from the tangential directions of the circumferences 92 and 93 when the water spray surface 85 is viewed in a plan view. Further, the inclination components α 1, α 2 with respect to the normal directions U1, U2 are larger for the 1 st through hole group 81 than for the 2 nd through hole group 82 for the inclination component α 1, α 2.
According to such a configuration, in a state where the 1 st through hole 81J located on the outer side has a rotation component in the circumferential direction of the circumferences 92 and 93 larger than the 2 nd through hole 82J located on the inner side, the water is ejected toward the center side of the water spray plate 84 and then diverged in a direction away from the center. Such a shower film capable of forming a spiral flow of two or more layers can be formed, and a water discharge form different from that in general can be realized.
Further, according to the water spray plate 84 of embodiment 3, in the 1 st through hole group 81 and the 2 nd through hole group 82, the inclination component β 1 of the 1 st through hole group 81 is larger than the inclination component β 2 of the 2 nd through hole group 82 with respect to the inclination components β 1 and β 2 of the ejection directions 87 and 89 with respect to the thickness direction T of the water spray plate 84.
With this configuration, in a state where the 1 st through hole 81J positioned on the outer side has a larger rotation component in the direction parallel to the water discharge surface 85 than the 2 nd through hole 82J positioned on the inner side, the water is discharged toward the center side of the water discharge plate 84 and then diverges in a direction away from the center. Such a shower film capable of forming a spiral flow of two or more layers can be formed, and a water discharge form different from that in general can be realized.
As described above, according to the shower apparatus 80 of embodiment 3, the 1 st through-hole 81J as the 1 st spout hole is positioned outside the 2 nd through-hole 82J as the 2 nd spout hole. Further, when the water discharge surface 85 is viewed in plan, the discharge directions 87 and 89 as the center lines of the 1 st through hole 81J and the 2 nd through hole 82J extend from the upstream side to the downstream side in a direction closer to the centers of the circumferences 92 and 93 than the tangential directions of the circumferences 92 and 93 in the through holes 81J and 82J. The inclination component α 1 of the ejection direction 87 of the 1 st through hole 81J with respect to the normal direction U1 is larger than the inclination component α 2 of the ejection direction 89 of the 2 nd through hole 82J with respect to the normal direction U2.
According to such a configuration, in a state where the 1 st through hole 81J located on the outer side has a rotation component in the circumferential direction of the circumferences 92 and 93 larger than the 2 nd through hole 82J located on the inner side, the water is ejected toward the center side of the water spray plate 84 and then diverged in a direction away from the center. Such a shower film capable of forming a spiral flow of two or more layers can be formed, and a water discharge form different from that in general can be realized.
In the shower apparatus 80 according to embodiment 3, the inclination component β 1 of the discharge direction 87 of the 1 st through hole 81J and the thickness direction T of the water spray plate 84 is larger than the inclination component β 2 of the discharge direction 89 of the 2 nd through hole 82J and the thickness direction T of the water spray plate 84.
With this configuration, in a state where the 1 st through hole 81J positioned on the outer side has a larger rotation component in the direction parallel to the water discharge surface 85 than the 2 nd through hole 82J positioned on the inner side, the water is discharged toward the center side of the water discharge plate 84 and then diverges in a direction away from the center. Such a shower film capable of forming a spiral flow of two or more layers can be formed, and a water discharge form different from that in general can be realized.
In embodiment 3, a case where 3 sets of the through hole groups 81, 82, and 83 are provided has been described, but the present invention is not limited to this case, and the number of the sets of the through hole groups may be 2 or 4 or more.
In addition, by appropriately combining the various forms described above, effects possessed by each of the forms can be achieved.
The present invention has been fully described in connection with preferred embodiments with reference to the accompanying drawings, but various modifications and alterations will become apparent to those skilled in the art. Such changes and modifications are to be understood as included within the scope of the present invention as determined by the appended claims unless they depart therefrom.
