Description

  The present invention relates to a water discharge device and a bathtub device.

  A water discharging device that discharges a film-like water flow is known (for example, Patent Document 1 and Patent Document 2). When such a water discharge device is installed in the bathtub, a film-like water flow flows into the bathtub. When the bather puts his back on the bathtub below the water discharger and takes a bath, a water flow is applied to the shoulder of the bather, and a relaxing effect is obtained. In addition, when a film-like water stream flows into the bathtub, it is possible to provide a bathroom with excellent aesthetics and high added value.

FIG. 2 is a perspective view showing the water discharging device 1 according to the present embodiment. Hereinafter, description will be given based on an XYZ orthogonal coordinate system as appropriate.

  As shown in FIG. 1, the bathtub apparatus 100 includes a bathtub main body 101 in which hot water or water (hereinafter simply referred to as “hot water”) accumulates, and a flange 102. The bathtub body 101 has a substantially rectangular shape in plan view. The flange 102 extends from the upper edge, which is the upper end of the bathtub body 101, to the outside in a substantially horizontal direction, and the outer peripheral edge has a substantially rectangular shape in plan view.

  As shown in FIG. 1, the first inner wall 103 on the first side 1011 side that is one of the two short sides of the bathtub body 101 along the X direction is outward from the bottom 108 of the bathtub body 101 toward the flange 102. It is formed to be inclined. In the bathtub apparatus 100 according to the present embodiment, the bather is set to take a bath with the back facing the first inner wall 103. The first inner wall 103 is set at an inclination angle so that the bather can relax when the bather takes a bath against the first inner wall 103.

  The bathtub main body 101 includes a second inner wall 104 and a third inner wall 105 extending in the Y direction (second direction, third direction) substantially orthogonally from both ends of the first inner wall 103 in the X direction. The second side 1012 and the third side 1013 are long sides of the bathtub body 101.

  As shown in FIG. 1, the water discharge device 1 according to the present embodiment is provided on an upper portion of a bathtub body 101. The water discharge device 1 is a device that discharges a film-like water flow W from a water discharge port 2 to be described later into the bathtub body 101. In the water discharge device 1, the inner side surface 10 having a substantially U shape in plan view is disposed along the upper edge portion of the bathtub body 101, and is placed on the flange 102.

The water discharge device 1 according to the present embodiment includes a water discharge port 2, a water supply channel 4, a membranous water formation mechanism 3, and a cover member 5.
As shown in FIG. 2, the water discharge device 1 has a first side 11 extending in the X direction (first direction) toward the first inner wall 103 side, and both ends in the X direction of the first side 11 from the Y direction (first It has a second side 12 and a third side 13 extending in two directions and a third direction, and has a substantially U-shaped shape in plan view. Specifically, the first side 11 is disposed on the flange 102 near the first side 1011 at the upper end of the first inner wall 103 of the bathtub body 101. The second side portion 12 is disposed on the flange 102 in the vicinity of the second side 1012 at the upper end of a part of the second inner wall 104. The third side 13 is disposed on the flange 102 in the vicinity of the third side 1013 at the upper end of a part of the third inner wall 105 (see FIG. 1). The second side 12 and the third side 13 are extended substantially in parallel.

  The water outlet 2 is formed along the shape of the upper edge of the bathtub body 101. The upper edge is a boundary portion between the bathtub body 101 and the flange 102. In this embodiment, it has a substantially rectangular shape in plan view. Therefore, the water discharge port 2 is a slit-like opening extending in the horizontal direction on the substantially U-shaped inner side surface 10 formed by the first side portion 11, the second side portion 12, and the third side portion 13. The water outlet 2 is formed extending in three directions. A first spout 21 is formed on the entire length in the X direction (first direction) of the first side 11 on the inner side surface 10. A second water discharge port 22 extending in the Y direction is formed on the inner side surface 10 in the second side portion 12. In the third side portion 13, a third water discharge port 23 (see FIG. 6) extending in the Y direction is formed on the inner side surface 10. The first water outlet 21, the second water outlet 22, and the third water outlet 23 are continuously formed on the inner side surface 10.

  The shape of the water outlet 2 in a plan view is substantially U-shaped as long as the second water outlet 22 and the third water outlet 23 are opened in a direction different from the direction in which the first water outlet 21 opens. For example, the case where the planar view shape formed by the 1st water discharge port 21, the 2nd water discharge port 22, and the 3rd water discharge port 23 is a C-shape, a rectangle, and circular arc shape is included.

  As shown in FIG. 1, the first water outlet 21 of the water outlet 2 is longer than the second water outlet 22 and the third water outlet 23. Here, in a plan view, the short side direction (X direction shown in FIG. 1) in which the first inner wall 103 where the bather bathes in the back is extended is referred to as a width direction. A direction orthogonal to the width direction (X direction shown in FIG. 1) is referred to as a depth direction. In the water discharge port 2, the ratio between the maximum separation distance L1 between the ends of the water discharge ports 22 and 23 in the width direction and the dimensions L2 and L3 in the depth direction is L1: L2 (L3) = 1: 0.15 to 0.7. It is. In the present embodiment, since the second water outlet 22 and the third water outlet 23 are formed with the same dimensions, the dimension L2 and the dimension L3 in the depth direction are equal. For example, the maximum separation distance L1 is 800 mm, and the dimensions L2 and L3 are 400 mm.

  The maximum separation distance L1 is the maximum value of the separation distance in the width direction between the second water outlet 22 and the third water outlet 23. In this embodiment, the water discharge port 2 is provided along the shape of the upper edge part of the bathtub main body 101 of planar view substantially rectangular shape. Therefore, the separation distance between the second water outlet 22 and the third water outlet 23 is equal.

  In the water discharge port 2, the ratio between the maximum separation distance L1 between the ends of the water discharge ports 22 and 23 in the width direction and the dimensions L2 and L3 in the depth direction is L1: L2 (L3) = 1: 0.15-0. .7, a film-like water flow can be sufficiently discharged from the second water outlet 22 and the third water outlet 23 to the arm of the bather. Note that the lengths of the second water outlet 22 and the third water outlet 23 in the Y direction may be substantially equal to the second side 1012 and the third side 1013 of the bathtub body 101.

  In addition, the planar view shape of the bathtub main body 101 may not be a rectangle. For example, as in the modification shown in FIG. 8, the bathtub body 101A may have a substantially oval shape in plan view. In the case of the bathtub main body 101A shown in FIG. 8, the first inner wall 103A is formed to be curved from the center in the width direction (X direction shown in FIG. 8) toward the second inner wall 104A and the third inner wall 105A. . Therefore, the water discharge port 2A of the water discharge device 1A is also formed to be curved following the shape of the upper edge of each side 1011A, 1012A, 1013A of the bathtub body 101A. In this case, the maximum separation distance L1 between the second water outlet 22 and the third water outlet 23 is the first outlet of the second water outlet 22 and the third water outlet 23 in the depth direction (Y direction shown in FIG. 8). The distance between the end portions 22e and 23e on the opposite side to the water mouth 21 side. Since the central portion in the width direction of the first inner wall 103 is the most depressed in plan view, the dimensions L2 and L3 in the depth direction are the same as the point M at the central portion in the width direction of the first spout 21 and It is the length in the depth direction with the end portions 22e and 23e of the second water discharge port 22 or the third water discharge port 23.

  Returning to the description of the embodiment shown in FIG. A membrane-like water forming mechanism 3 is disposed inside the first side portion 11, the second side portion 12, and the third side portion 13 shown in FIG. 2, and a water supply path 4 provided below the flange 102. Connected with. The membranous water formation mechanism 3 is a mechanism for discharging hot water supplied from the water supply channel 4 from the water outlet 2 as a film-like water flow W. The membranous water forming mechanism 3 is provided along the slit-shaped water outlet 2.

  FIG. 3 is a configuration diagram schematically illustrating a water supply system of the water discharge device 1. As shown in FIG. 3, the water supply channel 4 is connected to the circulation port 107 (see FIG. 1) of the bathtub body 101 and the membranous water formation mechanism 3. The water supply channel 4 includes a pump P, and hot water stored in the bathtub body 101 is supplied to the membrane water formation mechanism 3 side through the water supply channel 4. Therefore, the hot water stored in the bathtub body 101 circulates through the water supply channel 4, the membranous water formation mechanism 3, and the water discharge port 2.

  FIG. 4 is a longitudinal sectional view showing the internal structure of the water discharging device 1 according to this embodiment. FIG. 4 shows a longitudinal sectional view in the Y direction at the first side 11 of the water discharger 1. The water discharge device 1 includes a membranous water formation mechanism 3. The membranous water formation mechanism 3 includes a lower member 36 connected to the water supply path 4, a cover member 5 provided above the lower member 36, and a partition wall 30. The membranous water forming mechanism 3 has the same structure at the first side, the second side, and the third side. Therefore, the membranous water forming mechanism 3 on the first side, the second side, and the third side has the same cross-sectional shape as FIG. Below, the structure of the membranous water forming mechanism 3 will be described by taking the first side portion 11 as an example.

  In the lower member 36, a lower end pipe 360 is inserted into a through hole 1021 that penetrates in the Z direction formed in the flange 102. A sealing material 106 is provided between the lower end pipe 360 and the through hole 1021 of the flange 102.

  The lower member 36 is formed with a through portion 361 that penetrates in the Z direction. An inner upper end 363 and an outer upper end 362 are provided at both ends in the Y direction of the penetrating part 361. The inner upper end portion 363 is formed with an inclined surface that is inclined upward from the end portion of the penetrating portion 361 in the Y direction toward the inner wall 364. The outer upper end portion 362 is formed with a horizontal plane from the end portion of the penetrating portion 361 in the Y direction to the outer wall 365. The outer upper end 362 has a horizontal plane at a position higher than the inner upper end 363.

  The cover member 5 is disposed on the outer upper end 362 of the lower member 36. The lower surface of the cover member 5 includes a lower protruding portion 51, a recessed portion 52, an inclined portion 53, and an outer cover portion 54. The lower protruding portion 51 protrudes downward at a position that contacts the outer upper end portion 362 of the lower member 36. The recess 52 is formed adjacent to the lower protrusion 51 in the Y direction and recessed upward. The inclined portion 53 is adjacent to the end portion of the concave portion 52 opposite to the lower protruding portion 51, and is inclined upward from the boundary portion with the concave portion 52 toward the inner wall 55. The outer cover portion 54 is a flat plate-like portion that is provided on the outer side in the Y direction with respect to the lower protrusion portion 51, spaced apart from the lower member 36, and extends downward from the lower member 36.

  The partition wall 30 is disposed so as to cover the upper opening of the through part 361. The concave portion 52 is disposed above the through portion 361 of the lower member 36 and the partition wall 30. The lower protrusion 51 is disposed in contact with the outer upper end 362. The outer wall 365 of the lower member 36 is covered with the outer cover portion 54.

  The inclined portion 53 is disposed opposite to the inner upper end portion 363 of the lower member 36 in the Z direction, and the throttle channel 35 is formed between the inclined portion 53 and the inner upper end portion 363 of the lower member 36. A gap between the inner wall 364 of the lower member 36 and the inner wall 55 of the cover member 5 serves as the water outlet 2.

  The membranous water forming mechanism 3 includes a first chamber 31 and a second chamber 32 that are separated by a partition wall 30 and are arranged in the vertical direction. The first chamber 31 and the second chamber 32 extend in the X direction and the Y direction along the water discharge port 2. The space of the penetrating portion 361 below the partition wall 30 is the first chamber 31, and the space surrounded by the partition wall 30 and the recess 52 is the second chamber 32.

  As shown in FIG. 4, an inlet 33 connected to the water supply path 4 is formed at the lower end of the first chamber 31. The opening area of the inflow port 33 is smaller than the plane area of the first chamber 31. A discharge port 34 communicating with the water discharge port 2 is formed in the second chamber 32. A throttle channel 35 is formed between the discharge port 34 and the water discharge port 2.

  The partition wall 30 is formed with a communicating portion 42 penetrating in the vertical direction, and the first chamber 31 and the second chamber 32 communicate with each other through the communicating portion 42. The communication portion 42 is an opening that is sufficiently small with respect to the plane area of the first chamber 31 and the second chamber 32. A plurality of communication portions 42 are formed at intervals in the extending direction (X direction and Y direction) of the membranous water forming mechanism 3.

  FIG. 5 is a longitudinal sectional view schematically showing the configuration of the membranous water forming mechanism 3. The operation of the membranous water formation mechanism 3 will be described with reference to FIG. Hot water supplied from the water supply channel 4 via the inflow port 33 spreads into the first chamber 31 and becomes full, and flows into the second chamber 32 via the communication portion 42. Hot water that has flowed into the second chamber 32 flows from the discharge port 34 toward the water discharge port 2 via the throttle channel 35. In the membranous water formation mechanism 3, the membranous water flow W is discharged from the water outlet 2 by the following action in the hot water flow path from the inlet 33 to the water outlet 2.

  First, since the partition wall 30 is provided, the hot water that has flowed into the first chamber 31 from the inlet 33 does not flow into the second chamber 32 at once, but the hot water that has flowed in the Z direction has a water flow within the first chamber 31. Distributed. Subsequently, the hot water dispersed in the first chamber 31 flows into the second chamber 32 via the communication portion 42. Since the opening area of the communication portion 42 is sufficiently small with respect to the plane area of the first chamber 31 and the second chamber 32, the second chamber 32 is maintained at a predetermined water force without being affected by the water force in the first chamber 31. Flow into. In the second chamber 32, the hot water is dispersed similarly to the first chamber 31, and the unevenness of the water in the second chamber 32 is reduced.

Next, the throttle channel 35 is a flat space that communicates with the slit-shaped water discharge port 2, has a small gap in the Z direction, and is wide in the horizontal direction. Therefore, the hot water in which the water is dispersed in the second chamber 32 flows into the discharge port 34 which is an opening that is sufficiently small with respect to the volume of the second chamber 32, and the water pressure rises in the throttle channel 35, The water force to water mouth 2 increases. Since the narrow channel 35 and the water discharge port 2 have a smaller gap in the Z direction than in the XY direction (horizontal direction), when hot water with high water pressure is discharged from the water discharge port 2, the film-like water flow W is horizontal. To leak.
In addition, since a plurality of communicating portions 42 are formed at intervals, the water flow discharged from the water discharge port 2 forms a uniform film-like water flow W without unevenness in the direction in which the water discharge port 2 extends.

  6 and 7 show examples of arrangement of the membranous water formation mechanism 3 in the water discharge device 1. FIG. As shown in FIG. 6, the membranous water formation mechanism 3 may be provided continuously on the first side 11, the second side 12, and the third side 13. Moreover, you may provide the membranous water formation mechanism 3 in the 1st edge part 11, the 2nd edge part 12, and the 3rd edge part 13 each independently like the modification shown in FIG. In this case, the throttle channels 35 of the three membranous water forming mechanisms 3 may be communicated in the horizontal direction or individually connected to the water outlet 2. Moreover, the membranous water formation mechanism 3 provided in each side part 11, 12, 13 may be controlled by the same system, or may be controlled individually.

  The water flow of the film-like water flow W discharged from the water discharge port 2 may be the same or different from each other for the first water discharge port 21, the second side portion 12, and the third side portion 13. By adjusting the flow rate in the membranous water formation mechanism 3 and the gap in the Z direction of the slit, the water outlets 21, 22, and 23 can have different water forces. For example, in the case of the bathtub main body 101 having a large dimension in the X direction of the first side 1011, the second water outlet 22 and the third water outlet 23 have a higher water pressure than the first water outlet 21, and the second water outlet 22. The film-like water flow W discharged from the third water discharge port 23 may be surely applied to the bather.

  According to the water discharge device 1 according to the present embodiment, the water discharge port 2 is formed in a shape along the shape of the upper edge portion of the bathtub main body 101, and the membrane-like water forming mechanism 3 is substantially U in plan view from the water discharge port 2. A letter-shaped film-like water flow W is discharged. As a result, the membrane-like water flow W is discharged in a wide range, and the water discharging device 1 having a high relaxing effect can be provided.

  According to the water discharge device 1 according to the present embodiment, the second water discharge port 22 and the third water discharge port extending in the direction Y intersecting the first direction X from both ends of the first water discharge port 21 in the X direction (width direction). 23. The spout 2 is spouted from the spout 2 because the ratio between the maximum separation distance L1 and the dimensions L2 and L3 in the depth direction is in the range of L1: L2 (L3) = 1: 0.15-0.7. The substantially U-shaped membranous water flow W in the plan view is sufficiently long in the depth direction Y with respect to the width direction X, and the membranous water flow W can be sufficiently applied from the shoulder of the bather to the arm. As a result, the membrane-like water flow W is discharged over a wide area from the neck to the arm of the bather, and the water discharging device 1 having a high relaxing effect can be provided.

  According to the bathtub apparatus 100 provided with the water discharging apparatus 1 which concerns on this embodiment, the film-like water flow W is discharged from the 1st water discharge port 21 to the whole region of the 1st edge | side 1011 of the bathtub main body 101, and the 2nd water discharge port 22 and A film-like water flow W is also discharged from the third water discharge port 23. As a result, the film-like water flow W is discharged from the upper edge portion of the bathtub main body 101 in a wide range in a substantially U shape in plan view. In particular, when a bather takes a bath close to the first inner wall 103, a film-like water flow W can be applied from the first spout 21 to the entire region from the neck to the shoulder of the bather. Therefore, the membrane-like water flow W is discharged in a wide range, and the bathtub apparatus 100 having a high relaxation effect can be provided. For example, when a film-like water flow W is applied not only to the bather's neck and shoulders but also to the arm side, a higher relaxing effect can be obtained. In addition, in the case of half-body bathing in which the lower body is mainly immersed in hot water in the bathtub, the upper body may cool if the temperature in the bathroom is low. According to the bathtub apparatus 100 according to the present embodiment, the upper body can be kept warm because a water flow is applied over a wide area from the neck to the arm protruding from the hot water surface during half body bathing.

  In the said embodiment, although the 2nd side part 12 and the 3rd side part 13 showed the example which is substantially equal length, even if the 2nd side part 12 and the 3rd side part 13 have different length, Good. When making the 2nd side part 12 and the 3rd side part 13 into different length, if the side part provided in the side near a washing place is shortened, it will be easy to move between a washing place and a bathtub. Moreover, although the 2nd side part 12 and the 3rd side part 13 showed the example extended substantially parallel, the 2nd water discharge port 22 and the 3rd water discharge port 23 should just open in the direction which mutually faces, and 2nd The side part 12 and the third side part 13 may not be arranged in parallel.

  In the said embodiment, although the 1st spout 21, the 2nd spout 22, and the 3rd spout 23 showed the example of the spout 2 currently formed in the inner side surface 10, the spout 2 is It is only necessary to be configured to extend in three directions so that a substantially U-shaped film-like water flow W in a plan view can be discharged from the water discharge port by the film-like water forming mechanism. Therefore, the water outlet is not limited to a configuration in which the first water outlet, the second water outlet, and the third water outlet are continuously formed. For example, no water outlet is provided at the corner of the first side and the second side, and the corner of the first side and the third side, the first water outlet, the second water outlet, and the first The ends of the first outlet and the third outlet are arranged at close positions, each outlet is formed independently, and the water flow discharged from each outlet is a substantially U-shaped membrane-like water flow W in plan view. The structure which becomes may be sufficient.

  In the said embodiment, although the example of the bathtub main body 101 of planar view substantially rectangular shape was shown, the shape of a bathtub is not limited to this. For example, the bathtub may have a square shape, an ellipse shape, or an oval shape (see FIG. 8) in plan view, and the water discharge device may have a first side part, a second side part depending on the shape of the upper edge part of the bathtub. A side part and a third side part may be provided. When the shape of the plan view is a square bathtub, any one side is the first side, and the sides extending in the other direction from both ends of the first side in the width direction are the second side and the third side. What is necessary is just to set it as the water discharging apparatus which has the water outlet which does. In addition, in the case of a bathtub having an elliptical shape in plan view, the edge that curves the end in the long side direction is the first side, and the edge that faces both ends in the short side direction is the second side and the third side, respectively.
