[Modes for carrying out the invention]

[0008] The embodiments of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited in any way to the embodiments described below, and may be implemented with appropriate modifications without departing from the spirit of this disclosure.

[0009] [First Embodiment] As shown in Figure 1, the bathtub 200 is rectangular in shape when viewed from above. The water discharge device 2A has a body 28 attached to the upper edge 210 of the part that constitutes the short side of the bathtub 200, and a flow path 90 formed inside the body 28. Hereinafter, the horizontal direction perpendicular to the flow direction of the hot water W in the flow path 90 will be referred to as the "lateral direction," and a shape that extends in the lateral direction will be referred to as "horizontally elongated."

[0010] The water spraying device 2A is horizontally long and flat, and the downstream end of the flow path 90 constitutes a horizontally long water discharge port 93. From the water discharge port 93, hot water W is discharged in a horizontally long film shape toward the bathtub 200, specifically, toward the shoulders of the bather.

[0011] As shown in FIG. 2, a water supply system 300 for supplying the hot water W in the bathtub 200 to the water spraying device 2A is provided between the bathtub 200 and the water spraying device 2A. The water supply system 300 includes, in order from the upstream side, a suction port 301, a first water supply pipe 302, a pump 303, and a second water supply pipe 304. The suction port 301 is provided on the inner surface of the lower part of the bathtub 200. The first water supply pipe 302 connects the suction port 301 and the pump 303. The second water supply pipe 304 connects the pump 303 and the water spraying device 2A. The pump 303 sucks the hot water W in the bathtub 200 through the first water supply pipe 302 and pumps it to the water spraying device 2A through the second water supply pipe 304.

[0012] As shown in FIG. 3, the body 28 is divided into a horizontally long first body 30 and a horizontally long second body 40.

[0013] As shown in FIG. 4, the first body 30 has a cylindrical introduction part 31 protruding downward. The inside of the cylindrical introduction part 31 constitutes an introduction hole 90h. A base plate 20 is interposed between the upper edge part 210 of the bathtub 200 and the first body 30. The base plate 20 has a cylindrical base projection 21 that is externally fitted to the introduction part 31 of the first body 30, and the downstream end of the second water supply pipe 304 is connected to the base projection 21 through a cylindrical connection member 10. Thereby, the water supply system 300 is connected to the introduction hole 90h through the base plate 20 and the connection member 10.

[0014] The second body 40 is attached with a horizontally long lighting device 60 and a horizontally long lighting cover 70. The second body 40 is combined with the first body 30 from above and is coupled by screws or the like. A horizontally long storage chamber 91, a horizontally long throttle passage 92, and a horizontally long discharge port 93 are formed between the first body 30 and the second body 40. An introduction hole 90h communicates with the bottom surface of the storage chamber 91. A plurality of columns 34 for passing the aforementioned screws are protrudingly provided on the first body 30. The columns 34 pass through the inside of the storage chamber 91.

[0015] A horizontally long rectifying disk 35 is installed in the storage chamber 91. The rectifying disk 35 has rectifying holes 36 penetrating in the vertical direction arranged horizontally and has screw through holes 37 for passing the aforementioned screws arranged horizontally. The throttle passage 92 communicates with the side surface of the storage chamber 91 on the bathtub 200 side. The throttle passage 92 has a smaller flow path cross-sectional area than the storage chamber 91. The discharge port 93 communicates with the end of the throttle passage 92 on the bathtub 200 side.

[0016] In the present embodiment, the first body 30 is a molded product such as resin, but it may be otherwise. Specifically, for example, the first body 30 may be formed by welding a plurality of divided bodies. Also, for example, the first body 30 may be made of metal or the like. Similarly, the second body 40 may be a molded product such as resin or may be otherwise.

[0017] As shown in FIG. 5, the flow path 90 has, in order from the upstream side, an introduction hole 90h, a storage chamber 91, a throttle passage 92, and a discharge port 93. Hereinafter, the portion of the storage chamber 91 located below the rectifying disk 35 is referred to as the "lower chamber of the storage chamber 91", and the portion of the storage chamber 91 located above the rectifying disk 35 is referred to as the "upper chamber of the storage chamber 91".

[0018] An inlet 90h is connected to the lower chamber of the storage chamber 91, and a throttling channel 92 is connected to the upper chamber of the storage chamber 91. The hot water W supplied to the lower chamber of the storage chamber 91 from the inlet 90h spreads laterally and is supplied to the upper chamber of the storage chamber 91 while being rectified as it passes through the rectifying holes 36 which are arranged in parallel in the horizontal direction. This makes it easier for the hot water W to spread evenly in the horizontal direction. After that, the hot water W passes through the horizontally elongated throttling channel 92 and is discharged in a horizontally elongated film shape from the horizontally elongated discharge port 93.

[0019] Hereinafter, the flow direction in the throttling channel 92 and the discharge port 93 will be referred to as "forward," and the left, right, and rear sides when facing forward will be referred to as "left," "right," and "rear," respectively.

[0020] In this embodiment, the three components, the first body 30, the second body 40, and the lighting device 60, constitute the entire wall of the flow path 90. In other words, these three components constitute the entire wall of the inlet hole 90h, the entire wall of the storage chamber 91, the entire wall of the throttling flow path 92, and the entire wall of the discharge port 93.

[0021] "The entire wall of the inlet hole 90h" refers to the entire inner surface around the flow direction in the entire section of the inlet hole 90h in the flow direction. In other words, since the flow direction of the inlet hole 90h is upward, "the entire wall of the inlet hole 90h" refers to the entire inner surface around the vertical direction in the entire section of the inlet hole 90h in the vertical direction.

[0022] "All walls of the storage chamber 91" refers to the bottom surface, ceiling surface, left inner surface, right inner surface, front inner surface, and rear inner surface of the storage chamber 91.

[0023] "The entire wall of the aperture channel 92" refers to the entire inner surface around the direction of flow in the entire section of the aperture channel 92 in the direction of flow. In other words, since the direction of flow in the aperture channel 92 is forward, "the entire wall of the aperture channel 92" refers to the bottom surface, left inner surface, top surface, and right inner surface of the aperture channel 92.

[0024] "The entire wall of the discharge port 93" refers to the entire inner surface around the flow direction in the entire section of the discharge port 93 in the flow direction. In other words, since the flow direction of the discharge port 93 is forward, "the entire wall of the discharge port 93" refers to the bottom surface, left inner side surface, top surface, and right inner surface of the discharge port 93.

[0025] Of the three components, the first body 30 comprises the entire wall of the inlet hole 90h, the lower wall of the storage chamber 91, the lower wall of the throttling channel 92, and the lower wall of the discharge port 93. The second body 40 comprises the upper wall of the storage chamber 91 and the portion of the upper wall of the throttling channel 92 other than the portion composed of the lighting device 60. For example, the "lower wall of the storage chamber 91" consists of the entire bottom surface of the storage chamber 91 and the lower parts of the left inner surface, right inner surface, front inner surface, and rear inner surface of the storage chamber 91.

[0026] The lighting device 60 comprises the portion of the throttling flow path 92 other than the portion of the ceiling wall that is not composed of the second body 40, and the portion of the discharge port 93 other than the portion of the ceiling wall that is not composed of the second body 40.

[0027] As shown in Figure 6, the second body 40 is provided with a horizontally elongated recess 48 that opens toward the bathtub 200 side and downward. A lighting device 60 is installed in this recess 48. The lighting device 60 has a light-emitting element 62 such as an LED and a waterproof and light-transmitting light-emitting element cover 63 that covers the light-emitting element 62. The light-emitting element cover 63 constitutes part of the ceiling wall of the throttling channel 92 and part of the ceiling wall of the discharge port 93.

[0028] The lighting device 60 illuminates the hot water W discharged from the outlet 93. Specifically, the light emitted from the lighting device 60 towards the bathtub 200 directly illuminates the hot water W discharged from the outlet 93. The light emitted downward from the lighting device 60 illuminates the wall of the flow path 90. The light reflected from that wall overflows from the outlet 93 and illuminates the hot water W discharged from the outlet 93.

[0029] A watertight packing P is provided between the first body 30 and the second body 40. Similarly, a packing (not shown) is provided between the light-emitting body cover 63 and the second body 40.

[0030] A through hole 211 is provided in the upper edge of the bathtub 200, extending vertically. A connecting member 10 is inserted into the through hole 211. A male screw 10a is provided on the outer surface of the connecting member 10, and a nut 11 is screwed onto the male screw 10a from below, thereby attaching the water discharge device 2A to the upper edge 210 of the bathtub 200.

[0031] The configuration and effects of this embodiment are summarized below.

[0032] The lighting device 60 forms part of the wall of the flow path 90. Therefore, it can illuminate the hot water W discharged from the outlet 93 from a close distance. In other words, the distance between the discharged hot water W and the lighting device 60 can be kept small. This makes the hot water W discharged from the outlet 93 look more appealing. Since the lighting device 60 forms part of the wall of the flow path 90, it saves space for the lighting device 60 to be installed.

[0033] The waterproof and light-transmitting light-emitting body cover 63, which covers the light-emitting body 62, constitutes a portion of the wall of the channel 90. Therefore, the light-emitting body cover 63 can be used to constitute a portion of the wall of the channel 90.

[0034] The lighting device 60 forms part of the wall of the discharge port 93 within the flow path 90. Therefore, it can directly illuminate the hot water W discharged from the discharge port 93 from a very close distance.

[0035] The lighting device 60 further constitutes the wall of the diaphragm channel 92, and the light irradiated downward from the lighting device 60 illuminates the wall of the diaphragm channel 92. The light reflected from this wall overflows from the discharge port 93 and illuminates the hot water W discharged from the discharge port 93. Therefore, the hot water W can be illuminated indirectly, and the shimmering of the light passing through the hot water W can create an aesthetically pleasing effect.

[0036] The flow path 90 has, in order from the upstream side, a storage chamber 91 into which the hot water W flows, a constricted flow path 92 with a smaller flow path cross-sectional area than the storage chamber 91, and a discharge port 93 that discharges the hot water W toward the bathtub 200, and each of these extends laterally. Therefore, the hot water W can be efficiently spread laterally and efficiently form a film-like layer of hot water W.

[0037] Other embodiments are described below. The following embodiments will be described based on the specified embodiment, focusing on the differences, and explanations of aspects that are the same as or similar to the specified embodiment will be omitted as appropriate.

[0038] [Second Embodiment] The water discharge device 2B of the second embodiment will be described based on the first embodiment. As shown in Figure 7, in this embodiment, the lighting device 60 is attached to the upper surface of the first body 30, not the lower surface of the second body 40. The lighting device 60 constitutes the lower wall portion downstream of the throttling flow path 92 and the lower wall portion of the discharge port 93. Specifically, as shown in Figure 8, the lighting device 60 is installed in a horizontally elongated recess 38 provided on the upper part of the first body 30.

[0039] This embodiment can be suitably adopted when it is easier to install the lighting device 60 on the first body 30 than on the second body 40, or when it is desired to illuminate the hot water W discharged from the outlet 93 from below.

[0040] [Third Embodiment] The water discharge device 2C of the third embodiment will be described based on the first embodiment. As shown in Figure 9, the lighting device 60 is attached to the ceiling of the storage chamber 91. Specifically, as shown in Figure 10, the second body 40 is provided with a horizontally elongated through-hole 46 that penetrates vertically for attaching the lighting device 60. The lighting device 60 is attached to the through-hole 46, and a hole cover 47 is also attached. The light-emitting body cover 63 of the lighting device 60 constitutes part of the ceiling wall of the storage chamber 91. The lighting device 60 illuminates the inside of the storage chamber 91. The light reflected inside the storage chamber 91 overflows from the discharge port 93 to the outside of the water discharge device 2C, illuminating the hot water W discharged from the discharge port 93.

[0041] In this embodiment, the lighting device 60 forms part of the wall of the storage chamber 91 and illuminates the inside of the storage chamber 91. The light reflected from within the storage chamber 91 illuminates the hot water W discharged from the outlet 93. Therefore, this embodiment can be suitably adopted when it is desired to illuminate the hot water W discharged from the outlet 93 indirectly rather than directly, when the aforementioned flickering effect is to be emphasized, or when it is desired to avoid the light source entering the eyes.

[0042] [Fourth Embodiment] Next, the water discharge device 2D of the fourth embodiment will be described based on the previous third embodiment. As shown in Figure 11, the body 28 does not have a through hole for installing the lighting device 60, and the lighting device 60 is sandwiched vertically between the first body 30 and the second body 40 on the side opposite to the bathtub 200 side of the storage chamber 91. The end face of the lighting device 60 on the bathtub 200 side constitutes part of the side wall of the storage chamber 91. In other words, the lighting device 60 is sandwiched in a predetermined direction between the first body 30 and the second body 40, and the end of the lighting device 60 on the side perpendicular to the predetermined direction constitutes part of the wall of the flow path 90.

[0043] According to this embodiment, by installing the lighting device 60 between the first body 30 and the second body 40, the lighting device 60 can be installed inside the body 28 without providing through holes or the like in the body 28.

[0044] [Fifth Embodiment] Next, the water discharge device 2E of the fifth embodiment will be described based on the previous fourth embodiment. As shown in Figure 13, the lighting device 60 has a light guide plate 65 for guiding the light emitted from the light-emitting element 62. The light guide plate 65 is sandwiched vertically between the first body 30 and the second body 40. The parts of the lighting device 60 other than the light guide plate 65 are installed on the outside of the body 28, specifically on the side of the body 28 that is closer to the bathtub 200.

[0045] Figure 14 is a configuration diagram of Figure 13 viewed from above. In a plan view from above, the light guide plate 65 has a U-shape that opens towards the bathtub 200, and its horizontally inward surface constitutes the wall of the flow path 90. Specifically, the light guide plate 65 constitutes the side wall opposite the bathtub 200 side in the storage chamber 91, the side walls on both sides in the lateral direction in the storage chamber 91, the side walls on both sides in the lateral direction in the constricted flow path 92, and the side walls on both sides in the lateral direction in the discharge port 93. The flow path 90 is illuminated from three directions by the light spilling out from the light guide plate 65: the side opposite the bathtub 200 side and both sides in the lateral direction.

[0046] As shown in Figure 15, a watertight packing P is provided between the light guide plate 65 and the first body 30, and between the light guide plate 65 and the second body 40.

[0047] According to this embodiment, the light guide plate 65 constitutes a portion of the wall of the flow path 90. Therefore, the light guide plate 65 can be used to constitute a portion of the wall of the flow path 90.

[0048] [Change form] The above embodiments can be implemented with modifications as follows, for example: The flow straightening valve 35 may be omitted if the hot water W can be discharged in a sufficiently clean, elongated film shape without it. A second flow path separate from the flow path 90 may be provided to discharge the hot water W towards the bather's neck. [Explanation of symbols]
