The second side 1012 and the third side 1013 are long sides of the bathtub body 101.

  As shown in FIG. 1, a slit-like opening 110 extending in the X direction is formed in the first inner wall 103. The opening 110 is formed on the inner wall surface below the lowermost end of the flange 102. In the present embodiment, the opening 110 is formed at a position slightly lower than the upper end of the first inner wall 103. The opening 110 is formed over substantially the entire width of the first inner wall 103. As shown in FIG. 2, the water discharge port 2 is disposed in the opening 110 that penetrates into and out of the first inner wall 103.

  An overflow hole 117 is formed in the fourth inner wall 109. The overflow hole 117 allows hot water to be discharged out of the bathtub body 101 from the overflow hole 117 when the water level in the bathtub body 101 rises and reaches the overflow hole 117. Therefore, the overflow hole 117 defines the upper limit h2 of the amount of water stored in the bathtub body 101.

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, 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. The hot water discharged from the overflow hole 117 to the outside of the bathtub main body 101 is connected to a drainage channel and drained together with a drain port 119 formed in the bottom portion 108 of the bathtub main body 101.

  FIG. 4 is a longitudinal sectional view showing the internal structure of the bathtub body 101 and the water discharge device 1 according to this embodiment. FIG. 4 is a longitudinal sectional view of the first inner wall 103 in the Y direction. 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, an upper member 5 provided above the lower member 36, and a partition wall 30.

  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 upper member 5 is disposed on the outer upper end 362 of the lower member 36. The lower surface of the upper member 5 includes a lower protrusion 51, a recess 52, and an inclined portion 53. 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 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 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. At the downstream end of the throttle channel 35, there are a first protrusion 201 and a second protrusion 202 in which the inner wall 364 of the lower member 36 and the inner wall 55 of the upper member 5 protrude in the Y direction toward the first inner wall 103, respectively. Have. A gap between the first projecting portion 201 and the second projecting portion 202 becomes 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 communication portions 42 are formed at intervals in the X direction, 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. The

  The water discharge port 2 is provided over substantially the entire width of the first inner wall 103 in the X direction. The first projecting portion 201 and the second projecting portion 202 are inserted into the opening 110 of the first inner wall 103, and are disposed so as to be waterproofed between the opening 110. As shown in FIG. 4, the first protrusion 201 and the second protrusion 202 are disposed so as to be substantially flush with the first inner wall 103 in the opening 110.

  As shown in FIG. 2, the water outlet 2 is disposed slightly below the upper end of the bathtub body 101. When the adult bather takes a bath with his / her back against the first inner wall 103, the spout 2 is discharged so that a film-like water flow wraps around the bather's shoulder. As described above, when the hot water height h2 in the bathtub body 101 reaches the overflow hole 117, the hot water flows out of the overflow hole 117. The water discharge port 2 is provided at a position higher than the overflow hole 117. Therefore, even if the hot water stored in the bathtub main body 101 increases, it does not reach the water discharge port 2 provided below the upper end portion of the bathtub main body 101. Therefore, the hot water stored in the bathtub main body 101 becomes full and does not flow backward to the water outlet 2.

  According to the bathtub device 100 according to the present embodiment, the water discharge device 1 is disposed on the side of the bathtub main body 101, and is disposed in the opening 110 formed in the first inner wall 103 of the bathtub main body 101 by the membranous water forming mechanism 3. A film-like water flow is discharged from the discharged water outlet 2. As a result, a gap generated around the outside of the bathtub main body 101 can be effectively used as a storage space for the water discharge device 1. Moreover, since only the spout 2 can be seen on the inner wall surface of the bathtub main body 101 on the external appearance, it can be set as the bathroom of a simple external appearance with few unevenness | corrugations. Furthermore, as compared with the prior art in which a water discharge device is provided above the bathtub body, there are no irregularities or small gaps on the flange 102, and the periphery of the bathtub body 101 is easy to clean.

  According to the bathtub device 100 according to the present embodiment, since the bathtub body 101 includes the overflow hole 117, when the water level in the bathtub body 101 rises and reaches the overflow hole 117, the overflow from the overflow body 117 to the outside of the bathtub body 101. Hot water is discharged. Since the overflow hole 117 that determines the upper limit of the amount of water stored in the bathtub body 101 is formed at a position lower than the water outlet 2, the water stored in the bathtub body 101 does not reach the water outlet 2, It is possible to prevent the water stored in the bathtub body 101 from flowing back to the water inlet 2.

  According to the bathtub device 100 according to the present embodiment, since the water discharge port 2 is provided over substantially the entire width of the first inner wall 103 of the bathtub body 101 having a substantially rectangular shape in plan view, a film-like water flow can be discharged in a wide range. . Therefore, if the bather takes a bath with his back against the first inner wall 103, a film-like water flow can be applied over a wide area around the shoulder of the bather. Moreover, when the film-like running water is discharged over substantially the entire width of the first inner wall 103, it is possible to provide the bathtub device 100 having excellent appearance design.

In the case of the bathtub main body 101C shown in FIGS. 12 and 13, the first inner wall 103C is formed by being curved from the center in the width direction (X direction shown in FIG. 13) toward the second inner wall 104C and the third inner wall 105C. Has been. Therefore, the spout 2C is also curved and formed following the shape of the upper edge of the bathtub body 101C. In this case, the maximum separation distance L1 between the second water outlet 22C and the third water outlet 23C is the first outlet of the second water outlet 22C and the third water outlet 23C in the depth direction (the Y direction shown in FIG. 13). This is the distance between the end portions 22e and 23e on the opposite side to the water mouth 21C side. In plan view, since the central portion in the width direction of the first inner wall 103 is the most depressed position, the dimensions L2 and L3 in the depth direction (direction Y) are points at the center portion in the width direction of the first water discharge port 21C. M is the length in the depth direction between the end 22e and 23e of the second water outlet 22C or the third water outlet 23C.

Returning to the description of the second embodiment shown in FIG. As shown in FIG. 8, the water discharge device 1 has a substantially U shape in plan view along the water discharge port 2 </ b> B.
As shown in FIG. 9, the water discharger 1 </ b> B includes a first side 11 extending in the X direction (first direction) on the first inner wall 103 side, and a Y direction (second direction, A second side 12 and a third side 13 extending in the third direction). The second side 12 and the third side 13 are extended substantially in parallel. The water discharger 1 </ b> B is disposed below the flange 102.

  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, and is connected to a water supply path 4 provided below the flange 102. Yes. 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. The configuration of the membranous water formation mechanism 3 is the same as that of the first embodiment.

  9 and 10 show examples of arrangement of the membranous water formation mechanism 3 in the water discharger 1B. As shown in FIG. 9, 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 2B 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 </ b> A in which the dimension of the first side 1011 in the X direction is large, 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 bathtub device 100B according to the present embodiment, the gap generated around the outside of the bathtub body 101 can be effectively used as a storage space for the water discharge device 1 as in the first embodiment. Moreover, since only the spout 2B can be seen on the inner wall surface of the bathtub main body 101 on the external appearance, it can be set as the bathroom of the simple external appearance with few unevenness | corrugations.

  According to the bathtub apparatus 100B according to the present embodiment, the water discharge port 2B is formed to extend in three directions on the plurality of inner walls 103, 104, 105 of the bathtub main body 101, and from the water discharge port 2B by the membranous water forming mechanism 3. A substantially U-shaped film-like water flow in a plan view is discharged. As a result, a film-like water flow is discharged from a wide range from three directions in the bathtub body 101. Therefore, when a bather takes a bath with the back against the first inner wall 103, a film-like water flow can be applied over a wide area from the shoulder to the arm of the bather, and a bathtub device 100B having a high relaxing effect can be provided. 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.

  According to the bathtub apparatus 100B according to the present embodiment, the second water outlet 22 and the third water outlet that extend in the direction Y intersecting the first direction X from both ends of the first water outlet 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 bathtub device 100B having a high relaxing effect can be provided.

  In the said embodiment, although the planar view shape of the bathtub main body 101 showed the substantially rectangular shape, the planar view shape of the bathtub main body 101 is not limited to this. For example, the shape of the bathtub body 101 in plan view includes shapes other than rectangles such as a square shape and an elliptical shape. In addition, when the planar view shape of the bathtub main body 101 is a square shape, the water discharge port 2 by setting any one inner wall as a 1st inner wall, and making two sides which adjoin and are orthogonal to a 1st inner wall into a 2nd inner wall and a 3rd inner wall. May be provided. In addition, for example, the bathtub body may have a circular or rectangular bathtub shape in plan view. In the case of such a deformed bathtub main body, the direction parallel to the longest part in the upper edge is referred to as the long side direction.

  For example, as in the modification shown in FIGS. 12 and 13, the shape of the bathtub body 101 </ b> A in plan view may be an oval shape. When the shape of the bathtub body 101A in plan view is an oblong shape, the first inner wall 103 on which the bather puts his back when taking a bath, and the second inner wall 104 and the third inner wall 105 that are curved from the first inner wall 103 and extend in different directions A slit-shaped opening 110C may be formed along the surface shape. Moreover, in this modification, the gentle curved surface is formed in the upper end part of the bathtub main body 101C to an outer periphery part.

  In the above embodiment, the example in which the overflow hole 117 is provided in the fourth inner wall 109 is shown, but the place where the overflow hole 117 is provided is not limited to this. The overflow hole 117 only has to be provided at a position where the overflow hole 117 is not blocked by the bather's body when the bather takes a bath against the first inner wall where the water discharge port 2 is provided. . For example, the second inner wall 104 and the third inner wall 105 may be used.

  In the said embodiment, although the slit-shaped opening part 110B (water discharge port 2B) showed the example formed in linear form in a horizontal direction, the slit-shaped opening part is not limited to this structure. For example, the opening is formed at a position where the first water outlet 21 of the first inner wall 103 on which the bather puts his back when taking a bath is higher than the second water outlet 23 and the third water outlet 23. The opening part which the both ends of the width direction and the 2nd water discharge port 22 or the 3rd water discharge port 23 connect in a curve form may be sufficient. In this case, the overflow hole 117 is formed at a position whose height is lower than the lowest position in the slit-shaped opening.
