(Embodiment 1) FIG. 1 is a schematic perspective view of the shower device 2 according to the first embodiment.

The shower device 2 shown in FIG. 1 is a bathroom shower device used in a bathroom. The shower device 2 shown in FIG. 1 is particularly an overhead shower device that is fixedly mounted on the ceiling 8 of the bathroom. As shown in FIG. 1 , the shower device 2 has a sprinkler plate 4 .

The sprinkler plate 4 is a plate-like member for sprinkling water. The sprinkler plate 4 has a sprinkler surface 5 . The sprinkler surface 5 is one surface of the sprinkler plate 4, and is provided so as to face downward. "Sprinkling surface" can also be called "sprinkling surface", "outflow surface" and so on.

As shown in FIG. 1 , a plurality of sprinkling holes 10 are formed on the sprinkling surface 5 . The sprinkler hole 10 is a through hole penetrating the sprinkler plate 4, and extends from the surface (outflow surface) of the sprinkler plate 4, that is, the sprinkler surface 5, to the back surface (inflow surface). The plural sprinkler holes 10 shown in FIG. 1 are arranged in a circular shape.

In the shower apparatus 2 of Embodiment 1, the structure of the water sprinkling hole 10 is elaborated. Specifically, it demonstrates using FIGS. 2-5.

FIG. 2 is a schematic plan view of the sprinkler plate 4 . In FIG. 2 , a plurality of sprinkler holes 10 are schematically shown, and the number of the sprinkler holes 10 is also simplified.

As shown in FIG. 2, when the watering surface 5 is planarly viewed, the plurality of watering holes 10 are arranged at intervals, and are arranged in a circular shape so as to overlap with the circle 9, which is an imaginary line. The center 11 of the circumference 9 is the center of the sprinkler surface 5 .

The water sprinkling holes 10 respectively form the openings at the downstream end, namely the downstream openings 12 and the openings at the upstream end, namely the upstream openings 14 . The downstream opening 12 is opened on the sprinkler surface 5 , and the upstream opening 14 is opened on the back surface of the sprinkler plate 4 opposite to the sprinkler surface 5 . The water passing through the sprinkling hole 10 flows from the upstream opening 14 to the downstream opening 12 (refer to reference numeral 20 ). In Embodiment 1, the downstream opening 12 and the upstream opening 14 are circular openings having approximately the same radius.

As shown in FIG. 2 , when the sprinkler surface 5 is viewed from above, the downstream openings 12 and the upstream openings 14 of each sprinkler hole 10 are arranged to be shifted. 3 and FIG. 4 are used for specific description.

FIG. 3 is an enlarged view of a portion of FIG. 2 showing a sprinkler hole 10. FIG. FIG. 4 is a view of arrows A-A of FIG. 2. FIG.

As shown in FIGS. 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 the circumference 9 . As shown in FIGS. 3 and 4 , the downstream opening 12 and the upstream opening 14 are staggered by staggering the opening center 16 and the opening center 18 along the surface direction F of the sprinkler plate 4 .

As shown in FIG. 4, the water sprinkling hole 10 of Embodiment 1 is formed by etching a plate-shaped member from both sides. The inner peripheral surface of the sprinkler plate 4 forming the sprinkler hole 10 has a first curved portion 22 and a second curved portion 24 . The first curved portion 22 is formed by etching the sprinkler plate 4 from the sprinkler surface 5 . The second curved portion 24 is formed by etching the sprinkler plate 4 from the back surface 21 .

Here, let the straight line connecting the opening center 16 and the opening center 18 be the center line 20 . The center line 20 is approximately the same as the traveling direction of the water in the sprinkler hole 10 . As mentioned above, since the opening center 16 and the opening center 18 are staggered in the surface direction F of the sprinkler plate 4 , the center line 20 extends to be inclined in the thickness direction T ( FIG. 4 ) of the sprinkler plate 4 .

Returning to FIG. 3 , when the sprinkler surface 5 is viewed from above, the direction in which the centerline 20 extends includes a slope component P1 with respect to the normal direction P of the circumference 9 and a slope component Q1 with respect to the tangential direction Q of the circumference 9 . By having an inclination component P1 with respect to the normal line direction P in particular, a different form of shower water can be realized from the general shower water. Specifically, it will be described using FIG. 5 .

5 : is a figure which shows the example of the form of the shower spray of the shower apparatus 2 of Embodiment 1. FIG. As shown in FIG. 5, the film|membrane of the shower which flows downward from each hole of the plurality of sprinkler holes 10 while being wound in the circumferential direction R is produced.

In the first embodiment, as shown in FIG. 3 in particular, the inclination component P1 of the center line 20 to the normal line direction P of the circumference 9 is set as the direction toward the circumferential direction R1, as shown in FIG. The inclination component towards the same circumferential direction R1. Thereby, the direction of the water sprayed from the sprinkler holes 10 can be unified into the circumferential direction R1, and the spiral water flow as shown in FIG. 5 can be generated, and the beautiful shower water can be realized. In addition, in Embodiment 1, the case where the inclination component P1 of the center line 20 was unified into the circumferential direction R1 was demonstrated, and design changes, such as changing to the circumferential direction R2 opposite to the circumferential direction R1, may be added.

Regarding the inclination component Q1 of the center line 20 , as shown in FIG. 3 , the direction in which the center line 20 extends from the upstream side to the downstream side is set to be farther from the center 11 ( FIG. 2 ) of the circumference 9 than the tangential direction Q of the circumference 9 direction. Moreover, as shown in FIG. 2, in all the water sprinkling holes 10, the same inclination direction is set. Thereby, the direction can be unified so that the water sprayed from the sprinkler hole 10 advances in a direction away from the center 11 of the circumference 9, and as shown in FIG. As a result, it is possible to generate a spiral water flow that extends from the water spray hole 10 to the outside and turns downward in the circumferential direction R, so that a beautiful shower water 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. Thereby, a water flow with an appropriate inclination angle can be generated.

In addition, the angle α between the center line 20 shown in FIG. 4 and the vertical direction 23 may be set to, for example, 5 degrees or more and 45 degrees or less. Thereby, a water flow with an appropriate inclination angle can be generated.

In addition, the angle β between the centerlines 20 of two adjacent sprinkler holes 10 in the plurality of sprinkler holes 10 shown in FIG. 2 can also be set to, for example, 0.15 degrees or more and 175 degrees or less. In this way, the interval between the sprinkler holes 10 can be appropriately set. At the same time, the water sprayed from the water spray holes 10 can be prevented from immediately converging, and the shower film shown in FIG. 5 can be formed, so that the beautiful shower water can be realized.

Next, the structure of the comparative example is shown in FIG. 6. FIG. FIG. 6 is a plan view schematically showing the sprinkler plate 100 of the comparative example.

As shown in FIG. 6 , a plurality of sprinkler holes 104 are formed on the sprinkler surface 102 of the sprinkler plate 100 . The plurality of sprinkler holes 104 are arranged in a circular shape, and are arranged on a circumference 107 based on the center 105 of the sprinkler surface 102 .

The sprinkler holes 104 are each formed with a downstream opening 106 and an upstream opening 108 . Let the straight line connecting the opening center 109 of the downstream opening 106 and the opening center 111 of the upstream opening 108 be the center line 110 . As shown in FIG. 6 , when the sprinkler surface 102 is viewed from above, the center line 110 of the sprinkler hole 104 is aligned with the normal direction of the circumference 107 of the sprinkler hole 104 . That is, the direction in which the center line 110 extends in plan view has no inclination component with respect to the normal direction of the circumference 107 . According to such a structure, although the water sprayed from the plurality of water spray holes 104 spreads to the outside and is away from the center 105, it advances downward without being swirled in the circumferential direction S. As shown in FIG.

On the other hand, according to the shower device 2 of the first embodiment, since the center line 20 has an inclination component P1 with respect to the normal line direction P of the circumference 9, a swirling component in the circumferential direction R can be generated, and a different shower can be realized. The form of the sprinkler is the form of the sprinkler.

In the present embodiment, attention is also paid to the lateral dimension of the water sprinkling hole 10 penetrating the through region from the upstream opening 14 to the downstream opening 12 linearly along the thickness direction T, and by setting the lower limit value and the upper limit value of the dimension, And achieve the desired water spray form. 7 and 8 are specifically used for description.

FIG. 7 is a plan view schematically showing the sprinkler plate 4 according to the first embodiment, and FIG. 8 is a view taken along arrow B-B in FIG. 7 . The cross-section shown in FIG. 8 is the same cross-section as FIG. 4 and includes the aforementioned center line 20 .

As shown in FIGS. 7 and 8 , each sprinkler hole 10 exists in a penetration region 200 that penetrates through the sprinkler plate 4 in the thickness direction T. As shown in FIG. The penetration region 200 is a region of the sprinkler hole 10 that linearly penetrates through the upstream opening 14 to the downstream opening 12 along the thickness direction T of the sprinkler plate 4 .

In the cross section shown in FIG. 8 , the penetration area 200 has a dimension X in the direction along the surface direction F of the sprinkler plate 4 , that is, in the lateral direction. The dimension X is defined by the distance in the plane direction F between the first inner edge portion 202 of the first curved portion 22 protruding inside and the second inner edge portion 204 of the second curved portion 24 protruding inside.

In the present embodiment, a lower limit value and an upper limit value are set for the dimension X in the lateral direction of the penetration region 200 of the cross section shown in FIG. The value is more than the upper limit value, and the plural watering holes 10 are formed.

According to such a design, in the structure in which the water is sprayed obliquely from the sprinkler hole 10, the clogging of the water in the sprinkler hole 10 can be suppressed, and the inclined water spray angle can be ensured.

If the dimension X is equal to or more than the lower limit value, when the water passes through the sprinkler hole 10 along the center line 20, a passage space for the water can be secured. Thereby, water can pass through smoothly, and clogging of water can be suppressed. In addition, if the dimension X is equal to or less than the upper limit value, when the water passes through the sprinkler holes 10 along the center line 20, the flow rate of the water flow 206 to be passed vertically downward along the thickness direction T can be restricted, so that the thickness direction can be ensured. The inclined water spray angle of T.

FIG. 9 shows an example of experimental results when an experiment was performed on the relationship between the dimension X in the transverse direction of the penetration region 200 and the water spray angle using the sprinkler plate 4 of the first embodiment. FIG. 9 is a graph showing the dimension X (unit: mm) on the horizontal axis and the water spray angle (unit: degree) on the vertical axis. The detailed conditions of the experiment are omitted.

As shown in FIG. 9 , a target water spray angle is set in advance regarding the angle of water spray from the water spray hole 10 . When the dimension X is 0.4mm or less, the water spray angle above the target water spray angle is achieved. On the other hand, when the dimension X is larger than 0.4 mm, the water spray angle is reduced and is lower than the target water spray angle. When it is lower than the target water spray angle, it is easy to flow vertically downward, and it is difficult to achieve an inclined water spray angle.

When the dimension X increases, the water spray angle decreases because, as explained with reference to FIG. 8 , the flow rate of the water flow 206 to pass vertically downward along the thickness direction T increases and is dominated by the water flow vertically downward.

In this embodiment, the lower limit value of dimension X is set to 0.1 mm, and the upper limit value is set to 0.4 mm. The plurality of sprinkler holes 10 were formed by controlling the dimension X in the lateral direction of the penetration region 200 in the range of 0.1 mm or more and 0.4 mm or less in each of the plurality of sprinkler holes 10 . According to this setting, when water is sprayed obliquely from the water spray hole 10, clogging of water can be suppressed, and an inclined water spray angle can be realized.

In the present embodiment, a set value (for example, 0.3 mm) is set between the lower limit value of 0.1 mm and the upper limit value of 0.4 mm, and the plurality of sprinkler holes 10 are formed so as to penetrate through each hole of the plurality of sprinkler holes 10. The dimension X of the area 200 is approximately the same set value. According to this setting, by unifying the dimension X in the lateral direction of the penetration area 200, the angle and flow rate of water sprayed from each water spray hole 10 can be made uniform.

As described above, according to the shower device 2 of the present embodiment, regarding the size of the penetration region 200 of each of the plurality of sprinkler holes 10 penetrating the upstream opening 14 to the downstream opening 12 linearly along the thickness direction T of the sprinkler plate 4, let Each hole of the plurality of sprinkler holes 10 is constituted so that the dimension X in the lateral direction including the cross section of the center line 20 is greater than or equal to a predetermined lower limit value and less than or less than a predetermined upper limit value.

According to such a structure, when water is sprayed obliquely from the water spray hole 10 , the clogging of water can be suppressed, and the inclined water spray angle can be ensured, so that a desired water spray form can be realized.

The downstream opening 90A opens into a circular shape on the water spray surface 85 , and the upstream opening 90B opens into a long hole shape on the back surface 220 . The water passing through the third through-hole 83J flows in the ejection direction 91 from the upstream opening 90B to the downstream opening 90A. The ejection direction 91 and the center line connecting the opening center of the upstream opening 90B and the opening center of the downstream opening 90A are approximately the same.

Similar to Embodiments 1 and 2, the discharge directions 87, 89, and 91 of the first through-hole 81J, the second through-hole 82J, and the third through-hole 83J include the normal directions U1, Slope components α1, α2, α3 of U2, U3. Thereby, water is sprayed in a "spiral shape" from the first through-hole group 81, the second through-hole group 82, and the third through-hole group 83, respectively, and a triple-spiral water spray form can be realized.

In Embodiment 3, in particular, the discharge directions 87, 89, and 91 of the first through-hole 81J, the second through-hole 82J, and the third through-hole 83J are all directed toward the center side with respect to the tangential direction of each circumference 92, 93, and 94. That is, the water sprayed from the first through-hole 81J, the second through-hole 82J, and the third through-hole 83J, respectively, is sprayed toward the center of the sprinkler plate 85 .

Furthermore, in Embodiment 3, the shape of each of the through holes 81J, 82J, 83J is set to a relationship of α1>α2>α3 with respect to the inclination components α1, α2, and α3 with respect to the normal directions U1, U2, and U3. That is, the inclination component α1 of the discharge direction 87 to the normal direction U1 is larger than the inclination component α2 of the discharge direction 89 to the normal direction U2, and the inclination component α2 of the discharge direction 89 to the normal direction U2 is larger than the normal direction U3. The inclination component α3 of the ejection direction 91 .

According to the setting of the inclination components α1, α2, and α3, among the through holes 81J, 82J, and 83J, the outer side of the through holes has a larger amount of components that advance in the direction of rotation of the circumference, and the water falls downward to The center side of the sprinkler plate 84 . The water sprayed from the first through-hole group 81, the second through-hole group 82, and the third through-hole group 83, respectively, converges on the center side, and then diverges in a direction away from the center. This triple helical water spray pattern can be achieved.

Next, longitudinal cross-sectional views of the first through-hole 81J, the second through-hole 82J, and the third through-hole 83J are shown in FIGS. 17A , 17B, and 17C. 17A is a K-K arrow view of the first through hole 81J of FIG. 16 , FIG. 17B is an L-L arrow view of the second through hole 82J, and FIG. 17C is an M-M arrow view of the third through hole 83J.

As shown in FIG. 17A , the spouting direction 87 of the water in the first through hole 81J has an inclination component β1 with respect to the thickness direction T of the sprinkler plate 84 . Similarly, as shown in FIG. 17B , the water ejection direction 89 of the second through hole 82J has an inclination component β2 with respect to the thickness direction T, and as shown in FIG. 17C , the water ejection direction 91 of the third through hole 83J has an inclination component β2 with respect to the thickness direction T The inclination component β3 of the direction T. As shown in FIG. 16 , any of the inclination components β1 , β2 , and β3 is a component toward the center side of the sprinkler surface 85 .

In the third embodiment, in particular, with respect to the inclination components β1, β2, and β3 in the thickness direction T, the shapes of the through holes 81J, 82J, and 83J are set in a relationship of β1>β2>β3. That is, the inclination component β1 of the discharge direction 87 is larger than the inclination component β2 of the discharge direction 89 , and the inclination component β2 of the discharge direction 89 is larger than the inclination component β3 of the discharge direction 91 .

According to the setting of the inclination components β1 , β2 , and β3 , among the through holes 81J, 82J, and 83J, the through holes located on the outer side have more components that advance in the direction parallel to the water spraying surface 85 , and the water falls down to The center side of the sprinkler plate 84 . When the water sprayed from the first through-hole group 81, the second through-hole group 82, and the third through-hole group 83 respectively forms a spiral water flow, the outer through-holes spray water with a stronger rotational component, and water is sprayed on the water. The flow on the center side of the plate 84, after converging on the center side, diverges to spread to the outside. This triple helical water spray pattern can be achieved.

According to the structure of the above-mentioned through holes 81J, 82J, 83J, the triple helical water flow as shown in FIG. 18 can be created. As shown in FIG. 18 , among the through-hole groups 81 , 82 , and 83 , the through-hole group located on the outer side has a stronger component in the direction parallel to the sprinkler surface 85 , that is, in the lateral direction. The composition ratio of the water sprayed from the first through-hole group 81 in the lateral direction is stronger than that of the water sprayed from the second through-hole group 82 , and the composition ratio of the water sprayed from the second through-hole group 82 in the lateral direction is higher than that of the water sprayed from the third through-hole group 83 . The water is strong. Since all the water sprayed from the through-hole groups 81 , 82 , and 83 falls toward the center, after the aggregation area 96 is temporarily aggregated, the water diffuses away from the center from the diverging area 98 . When the water is diffused in the diverging region 98 , among the through-hole groups 81 , 82 , and 83 , the through-hole groups located on the outer side are diverging in a direction away from the center.

According to this type of water spray, not only aesthetics, but also according to the purpose of use, it is possible to distinguish the part where the water is in contact with a larger contact area, such as the diverging region 98, and the part where the water is in contact with a smaller contact area, such as the polymerization region 96 . For example, when cleaning fingers or fine dirt, etc., as long as the object is placed in the aggregation area 96, it can be cleaned without wasting where the water is concentrated. On the other hand, as long as the object is placed on the divergent area 98, a large area such as a palm or an arm can be quickly washed. Moreover, when the shower apparatus 80 is installed in a large water tank, by utilizing the divergent area 98, it can flow efficiently in a large water tank.

Moreover, when water is sprayed into the circular bucket in the shower spray form of Embodiment 3, a swirling water flow can be generated in the bucket, and handkerchiefs and the like can be efficiently washed in the bucket. In addition, when a lotion is added, the blending of the lotion can also be made good.

Moreover, according to the shower water spray form of Embodiment 3, since it is a triple spiral water flow, wind can be generated around it. For example, when using a shower device as a bathroom, the user can feel the wind.

In Embodiment 3, similarly to Embodiments 1 and 2, the water sprinkling holes 81J, 82J, and 83J, in the thickness direction T, are focused on the lateral dimension of the penetration region from the upstream opening to the downstream opening. The lower limit value and the upper limit value are realized, and the desired water spray pattern is realized. Specifically, it demonstrates using FIGS. 19A-19C.

FIGS. 19A to 19C are cross-sectional views showing the penetration regions 222 , 224 , and 226 of the through holes 81J, 82J, and 83J, which have the same cross-sections as those of FIGS. 17A to 17C , respectively.

As shown in FIG. 19A , each sprinkler hole 81J has a first penetration region 222 that penetrates linearly in the thickness direction T of the sprinkler plate 84 . Similarly, as shown in FIG. 19B , each of the sprinkler holes 82J has a second penetration region 224 that penetrates linearly in the thickness direction T of the sprinkler plate 84 , and as shown in FIG. 19C , each of the sprinkler holes 83J has a second penetration region 224 in the sprinkler plate. The third penetration region 226 which penetrates linearly in the thickness direction T of 84 .

Therefore, as shown in FIGS. 19A to 19C , the first penetration region 222 includes the entire downstream opening 86A, the second penetration region 224 includes the entire downstream opening 88A, and the third penetration region 226 includes the entire downstream opening 90A.

In each of the cross sections of FIGS. 19A to 19C , the penetration regions 222 , 224 , and 226 have lateral dimensions X1 , X2 , and X3 . In Embodiment 3, the diameters of the downstream openings 86A, 88A, and 90A are set to approximately the same length. Therefore, the respective dimensions X1, X2, X3 of the penetrating regions 222, 224, 226 are approximately the same length.

In the third embodiment, the through-holes 81J, 82J, and 83J are configured so that the dimensions X1, X2, and X3 are the same as the lower limit value (eg, 0.1 mm) and the same upper limit value (eg, 0.4 mm) as in the first and second embodiments. mm) or less (eg 0.3mm). According to this design, as in Embodiments 1 and 2, the flow rate of the water flow to flow in the thickness direction T in the sprinkler holes 81J, 82J, and 83J, respectively, can be restricted, and the difference between the sprinkler holes 81J, 82J, and 83J can be suppressed. Water blockage, and can ensure the inclined water spray angle.

As described above, according to the shower device 80 of the third embodiment, the dimensions of the penetration regions 222, 224, and 226 of the plurality of sprinkler holes 81J, 82J, and 83J respectively include the size of the discharge directions (center lines) 87, 89, and 91, respectively. The lateral dimensions X1, X2, and X3 of the cross section are set to be equal to or larger than a predetermined lower limit value and equal to or smaller than a predetermined upper limit value.

According to such a structure, the clogging of the water passing through the sprinkling holes 81J, 82J, 83J can be suppressed by setting the limit and the upper limit of the lateral dimensions X1, X2, X3 of the penetrating regions 222, 224, 226, respectively, And it is easy to spray water obliquely. Thereby, the desired water spray form can be realized.

Moreover, in the shower apparatus 80 of Embodiment 3, the lower limit value of the dimension X1, X2, X3 is 0.1 mm, and the upper limit value is 0.4 mm. According to this structure, the clogging of the water in the water spray holes 81J, 82J, and 83J can be effectively suppressed, and the inclined water spray angle can be ensured.

Moreover, in the shower apparatus 80 of Embodiment 3, the penetration area|region 222,224,226 of each of the plurality of sprinkler holes 81J, 82J, 83J includes the whole downstream opening 86A, 88A, 90A. According to this structure, since the lateral dimensions of the downstream openings 86A, 88A, and 90A are consistent with the lateral dimensions X1, X2, and X3 of the penetration regions 222, 224, and 226, respectively, by adjusting the dimensions of the downstream openings 86A, 88A, and 90A, it is possible to adjust the The lateral dimensions X1, X2, X3 of the through regions 222, 224, 226. Thereby, the lateral dimensions X1 , X2 , X3 of the penetrating regions 222 , 224 , and 226 can be controlled with good precision, and the desired water spray pattern can be easily realized.

Moreover, in the shower apparatus 80 of Embodiment 3, the downstream openings 86A, 88A, 90A of each of the plurality of sprinkler holes 81J, 82J, and 83J are circular. According to such a configuration, by unifying the downstream openings 86A, 88A, and 90A into a circular shape, it is possible to suppress variations in the spraying directions and flow rates of the spraying holes 81J, 82J, and 83J.

Moreover, in the shower apparatus 80 of Embodiment 3, the upstream openings 86B, 88B, and 90B of each of the plurality of sprinkler holes 81J, 82J, and 83J are elongated holes. According to this structure, as shown in FIG. 16 , by changing the lengths of the upstream openings 86B, 88B, and 90B in the longitudinal direction, as shown in FIGS. 17A to 17C , the water spraying directions of the water spray holes 81J, 82J, and 83J can be easily adjusted. .

Furthermore, in the shower device 80 of the third embodiment, the sprinkler plate 84 is provided with a plurality of first sprinkler holes 81J arranged at intervals on the circumference 92, and the first sprinkler holes 81J are concentric with the first sprinkler holes 81J on the circumference. A plurality of second sprinkler holes 82J are arranged at intervals on the 93. The first watering hole 81J has a first penetration region 222 , and the second watering hole 82J has a second penetration region 224 . Regarding the size of the first penetration region 222 of each of the first sprinkler holes 81J penetrating the upstream opening 86B to the downstream opening 86A linearly in the thickness direction T, the lateral dimension X1 of the cross section including the ejection direction 87 is set to be equal to or greater than a predetermined lower limit value and below the predetermined upper limit value. As with the first sprinkler holes 81J, the size of the second penetration region 224 of each of the second sprinkler holes 82J linearly penetrating through the upstream opening 88B to the downstream opening 88A in the thickness direction T will include the size of the cross section in the ejection direction 89 . The lateral dimension X2 is set to be equal to or larger than the lower limit value and equal to or smaller than the upper limit value in the same manner as the first penetration region 222 .

According to such a structure, the 2nd water spray hole 82J is provided in addition to the 1st water spray hole 81J, and a double shower film can be sprayed. Furthermore, regarding the lateral dimension X2 of the second penetration region 224 of the second water spray hole 82J, the lower limit value and the upper limit value of the lateral dimension X1 of the first penetration region 222 are also applied, not only in the first water spray hole 81J. In the second water spray hole 82J, clogging of water can also be suppressed, and water can be easily sprayed obliquely, so that a desired water spray form can be realized. In addition, the design is facilitated by applying the same lower limit value and the same upper limit value to the respective lateral dimensions of the first penetration region 222 and the second penetration region 224 .

In addition, in the shower device 80 of the third embodiment, the angle β1 between the ejection direction 87 of the first sprinkler hole 81J and the thickness direction T of the sprinkler plate 84 is different from the angle β1 between the ejection direction 89 of the second sprinkler hole 82J and the sprinkler plate. The angle β2 contained by the thickness direction T of 84. According to this structure, even when the water spray angle of the first water spray hole 81J and the water spray angle of the second water spray hole 82J are different, the same lower limit value and the same lower limit value are applied with respect to the lateral dimensions X1 and X2 of the penetration regions 222 and 224. The upper limit value, no matter in the sprinkler holes 81J and 82J, can effectively suppress the clogging of water, and make the water easy to spray obliquely, which is also easy to design.

In addition, in Embodiment 3, the case where the group of three through-hole groups such as the through-hole groups 81, 82, and 83 is provided has been described, but it is not limited to this case, and the number of groups of the through-hole groups may be two. one or more than four.
