[Technical Field]

[0001] The present invention relates to a water discharge device. [Background technology]

[0002] A water discharger that discharges water in a wide, thin, waterfall-like shape is known (see, for example, Patent Document 1). In this water discharger, the inner surface of both ends of the longitudinal direction (left and right) of the waterfall spout is shaped to diverge, with the longitudinal width of the opening gradually increasing from the upstream side toward the downstream outlet. Furthermore, a strainer is installed upstream of the diverging part, acting as a flow straightening member, across the waterway. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-138648 Summary of the Invention [Problem to be solved by the invention]

[0004] The water discharge device of Patent Document 1 has a relatively complicated structure, as it is necessary to make the opening diverge and to install a strainer as a flow straightening member.

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a water discharger that has a simple structure and is capable of discharging water in a beautiful, wide, thin waterfall shape. [Means for solving the problem]

[0006] To achieve the above object, the present invention provides a water discharge device that discharges water in the form of a wide, thin waterfall, comprising: a supply section that supplies the water to be discharged; a retention section that is connected to the supply section and temporarily retains the supplied water while stirring it; a flat water discharge flow path that has an inlet that communicates with the retention section and through which the water retained in the retention section flows; and a water discharge outlet that is formed at the end of the water discharge flow path and opens horizontally. The water discharge outlet has a linear shape in a plan view. The retention section, the water discharge flow path, and the water discharge outlet are each formed by stacking multiple plate members, and the supply section is formed in one of the plate members that is located in the outermost layer in the stacking direction. [Effects of the Invention]

[0007] According to the present invention, the structure can be simplified without the need to make the inner surface of the water outlet flared or to install a strainer as a flow straightening member. Furthermore, since the retention section, water discharge flow path, and water outlet are each formed by stacking multiple plate members, it is easy to set the flow path width, flow path height, and internal volume of the water discharge flow path, as well as the height and internal volume of the retention section, to desired values. Therefore, according to the present invention, a water discharge device can be provided that can beautifully discharge water in the shape of a wide, thin waterfall with a simple structure.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The embodiments shown here are merely examples for embodying the technical concept of the present invention and are not intended to limit the present invention. Therefore, all other embodiments, examples, and operational techniques that can be conceived by those skilled in the art without departing from the spirit of the present invention are included in the scope and spirit of the present invention, as well as in the scope of the inventions set forth in the claims and their equivalents.

[0010] In addition, for the convenience of illustration and ease of understanding, the drawings attached to this specification may be represented schematically with the scale, aspect ratio, shape, etc. appropriately changed from the actual product, but these are merely examples and do not limit the interpretation of the present invention.

[0011] In this specification, ordinal numbers such as "first," "second," etc. may be used. However, unless otherwise specified, these ordinal numbers are used to identify components for the convenience of explanation, and do not specify the number or order.

[0012] <Embodiment> As shown in FIG. 1, a garden pan 100 is used as a water tray to receive water from a standpipe (not shown). The garden pan 100 is used outdoors in a garden, park, or the like by placing it on the ground or by embedding the side walls in the ground to a desired height. The garden pan 100 shown in the figure can be used by positioning the tallest of its four side walls, side wall 101, in front of the standpipe. An opening 102 is formed in side wall 101 and extends laterally. The water discharger 10 is installed behind the opening 102, and water is supplied to it via a hose 20. The water discharger 10 discharges water through the opening 102 in the form of a wide, thin waterfall.

[0013] As shown in Figures 2, 3, 4, and 5, water discharger 10 has supply unit 30 that supplies water to be discharged, retention unit 40 that is connected to supply unit 30 and temporarily retains the supplied water while stirring it, flat water discharge flow path 50 that has inlet 51 that communicates with retention unit 40 and through which the water retained in retention unit 40 flows down, and water discharge outlet 52 that is formed at the end of water discharge flow path 50 and opens horizontally. Water discharge outlet 52 has a linear shape in a plan view. Each of retention unit 40, water discharge flow path 50, and water discharge outlet 52 is formed by stacking multiple plate members 61 to 65, and supply unit 30 is formed in one plate member 61 (65) that is located in the outermost layer in the stacking direction.

[0014] The water discharger 10 of the embodiment is configured by stacking five plate members 61 to 65. For ease of explanation, the five plate members 61 to 65 will be referred to as the first plate member 61, the second plate member 62, the third plate member 63, the fourth plate member 64, and the fifth plate member 65, in that order from the bottom layer upward. Each of the plate members 61 to 65 has six bolt holes 70 formed therein, through which bolts (not shown) are inserted to fasten the stacked plate members 61 to 65 together.

[0015] The first plate member 61 and the fifth plate member 65 are located in the outermost layers in the stacking direction. The supply unit 30 is formed in one of the plate members 61 (65). In the illustrated example, the supply unit 30 is formed in the first plate member 61, which is the bottommost layer. The supply unit 30 is composed of a circular hole. A connector 21 to which a hose 20 is connected is connected to the supply unit 30.

[0016] The second plate member 62 is stacked on the first plate member 61. The second plate member 62 has a cutout portion 62a that is open on the front side (the front left side in FIG. 3), and has an arc-shaped wall surface 62b on the back side of the cutout portion 62a (the rear right side in FIG. 3).

[0017] The third plate member 63 is stacked on top of the second plate member 62. The third plate member 63 has a through hole 63a formed therein. The through hole 63a has a linear wall surface 63b on the front side and an arc-shaped wall surface 63c on the rear side. The third plate member 63 has a rectangular sealing portion 63d at a position closer to the front than the through hole 63a.

[0018] The fourth plate member 64 is stacked on the third plate member 63. A through hole 64a is formed in the fourth plate member 64. The through hole 64a has a linear wall surface 64b on the front side and an arc-shaped wall surface 64c on the rear side. The through hole 64a of the fourth plate member 64 has the same shape as the through hole 63a of the third plate member 63. When stacked, the through hole 64a of the fourth plate member 64 and the through hole 63a of the third plate member 63 overlap without creating a step. The dimension of the fourth plate member 64 in the front-rear direction is shorter than the dimension of the third plate member 63 in the front-rear direction, and a step portion 71 is formed on the front side. The front sides of the first to third plate members 61 to 63 are inserted into the opening 102 of the garden pan 100.

[0019] The fifth plate member 65 is stacked on the fourth plate member 64. The fifth plate member 65 seals the through-hole 64a of the fourth plate member 64.

[0020] The stagnation section 40 is formed between the first plate member 61 and the fifth plate member 65, and is formed by the cutout portion 62a of the second plate member 62, the through hole 63a of the third plate member 63, and the through hole 64a of the fourth plate member 64.

[0021] The water discharge flow path 50 is formed between the first plate member 61 and the sealing portion 63d of the third plate member 63, and is formed by the cutout portion 62a of the second plate member 62. The inlet 51 of the water discharge flow path 50 is formed between the first plate member 61 and the rear edge of the sealing portion 63d of the third plate member 63.

[0022] The water outlet 52 is formed between the front edge of the first plate member 61 and the front edge of the sealing portion 63d of the third plate member 63.

[0023] The water discharge flow path 50 has a constant flow path width W and flow path height h from the inlet 51 to the water discharge port 52 (see FIG. 5).

[0024] The height of the retention section 40 is higher than the flow path height h of the water discharge flow path 50, and the internal volume of the retention section 40 is set to be larger than the internal volume of the water discharge flow path 50. Here, the phrase "the height of the retention section 40 is higher than the flow path height h of the water discharge flow path 50" specifies that, although the internal volumes can be different even if the heights are the same, the water in the retention section 40 flows down into the water discharge flow path 50 in a squeezed manner.

[0025] The second plate member 62 has an arc-shaped wall surface 62b on the back side of the cutout portion 62a. The third plate member 63 has an arc-shaped wall surface 63c on the back side of the through-hole 63a. The fourth plate member 64 has an arc-shaped wall surface 64c on the back side of the through-hole 64a. Therefore, the inner wall surface of the retention section 40 facing the inlet 51 of the water discharge flow path 50 has an arc-shaped shape in plan view, with the distance L from the inlet 51 gradually decreasing from the widthwise center of the inlet 51 toward both widthwise ends (see Figure 5).

[0026] Next, the operation of the water discharger 10 will be described.

[0027] As shown in FIG. 4, water supplied from supply unit 30 to retention unit 40 via hose 20 is stirred and temporarily retained inside retention unit 40. At this time, the flow rate of the supplied water is made uniform inside retention unit 40. Furthermore, by temporarily retaining the water, the pressure of the water inside retention unit 40 becomes slightly higher than that of the water flowing through water discharge flow path 50. The water retained in retention unit 40 flows down into water discharge flow path 50 through inlet 51. As shown in FIG. 5, the water that flows down into water discharge flow path 50 is rectified while flowing inside water discharge flow path 50, and is discharged in the shape of a wide, thin waterfall from water discharge outlet 52, which has a linear shape in a plan view.

[0028] The water discharger 10 of the embodiment has a simplified structure, as it is not necessary to make the inner surface of the water discharge port 52 flared or to install a strainer as a flow straightening member. Also, since the retention section 40, water discharge flow path 50, and water discharge port 52 are each formed by stacking multiple plate members 61-65, it is easy to set the flow path width W, flow path height h, and internal volume of the water discharge flow path 50, and the height and internal volume of the retention section 40 to desired values. Therefore, with the water discharger 10 of the embodiment, water can be beautifully discharged in the shape of a wide, thin waterfall with a simple structure.

[0029] As explained above, the water discharger 10 of this embodiment has a supply unit 30 that supplies water to be discharged, a retention unit 40 that communicates with the supply unit 30 and temporarily retains the supplied water while agitating it, a flat water discharge flow path 50 that has an inlet 51 that communicates with the retention unit 40 and through which the water retained in the retention unit 40 flows down, and a water discharge outlet 52 that is formed at the end of the water discharge flow path 50 and opens horizontally. The water discharge outlet 52 has a linear shape in a plan view. The retention unit 40, the water discharge flow path 50, and the water discharge outlet 52 are each formed by stacking multiple plate members 61 to 65, with the supply unit 30 formed in one of the plate members 61 (65) that is located in the outermost layer in the stacking direction.

[0030] This configuration simplifies the structure, eliminating the need to make the inner surface of the water outlet 52 flared or to install a strainer as a flow straightening member. Furthermore, because the retention section 40, water discharge flow path 50, and water outlet 52 are each formed by stacking multiple plate members 61-65, it is easy to set the flow path width W, flow path height h, and internal volume of the water discharge flow path 50, as well as the height and internal volume of the retention section 40, to desired values. Therefore, a water discharger 10 can be provided that, with a simple structure, can beautifully discharge water in the shape of a wide, thin waterfall.

[0031] The water discharge flow path 50 has a constant flow path width W and flow path height h from the inlet 51 to the outlet 52. In this way, the water flowing down the water discharge flow path 50 is further straightened as it flows within the water discharge flow path 50, allowing the water to be discharged neatly in the shape of a wide, thin waterfall.

[0032] The height of the retention section 40 is greater than the flow path height h of the water discharge flow path 50, and the internal volume of the retention section 40 is greater than the internal volume of the water discharge flow path 50. In this way, the water supplied from the supply section 30 to the retention section 40 is further agitated inside the retention section 40, making the flow rate uniform. As a result, the water flowing down into the water discharge flow path 50 is further straightened as it flows within the water discharge flow path 50, allowing the water to be discharged neatly in the shape of a wide, thin waterfall.

[0033] The inner wall surface of the retention section 40 facing the inlet 51 of the water discharge flow path 50 has an arc shape in plan view, with the distance L from the inlet 51 gradually decreasing from the widthwise center of the inlet 51 toward both widthwise ends. In this way, the water supplied from the supply section 30 to the retention section 40 does not stagnate, and is further agitated inside the retention section 40, making the flow rate uniform. As a result, the water flowing down the water discharge flow path 50 is further straightened as it flows within the water discharge flow path 50, allowing the water to be discharged neatly in the shape of a wide, thin waterfall.

[0034] Although the embodiments of the present invention have been described, the present invention is not limited to the configurations described in the embodiments and can be modified as appropriate based on the claims. For example, the water-discharging device 10 can be incorporated into equipment for washing feet or bathing. The water-discharging device 10 can also be incorporated into equipment for giving water to or washing animals.

[0035] The following embodiments are also included within the scope of the present invention: the water discharger 10 according to claim 2 having the features of claim 3; the water discharger 10 according to claim 2 or 3 having the features of claim 4. [Explanation of symbols]
