[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. However, the present disclosure is not limited to the following embodiments, and can be appropriately modified and implemented without departing from the spirit of the present disclosure.
[0009] [First Embodiment] As shown in FIG. 1, the bathtub 200 is rectangular in a plan view seen from above. The water discharging device 1A has a body 28 attached above the upper edge 210 of a portion constituting the short side of the bathtub 200, a flow path 90 formed inside the body 28, and a lid body 50 which is separate from the body 28 and attached to the body 28. Hereinafter, the horizontal direction orthogonal to the flow direction of the hot water W in the flow path 90 is referred to as the "lateral direction", and a shape extending in the lateral direction is referred to as "horizontally long".
[0010] The water discharging device 1A 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, the 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 of the bathtub 200 to the water discharging device 1A is provided between the bathtub 200 and the water discharging device 1A. The water supply system 300 has, 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 discharging device 1A. The pump 303 sucks the hot water W of the bathtub 200 through the first water supply pipe 302 and pumps it to the water discharging device 1A through the second water supply pipe 304.
[0012] As shown in Figure 3, the body 28 is divided into a horizontally elongated first body 30 and a horizontally elongated second body 40. The lid 50 has a horizontally elongated shape. The lid 50 is attached to the body 28 in a manner that allows it to be removed from the body 28 while the body 28 is attached to the upper edge 210 of the bathtub 200. Specifically, the lid 50 may be fixed to the body 28 from above by screws (not shown), or by a snap-fit (not shown), etc.
[0013] As shown in Figure 4, the first body 30 has a cylindrical inlet portion 31 that protrudes downward. In this embodiment, there are two inlet portions 31, but there may be one or three or more. The inside of each cylindrical inlet portion 31 constitutes an inlet hole 90h. The downstream portion of the second water supply pipe 304 is branched into two, and the ends of each downstream portion are connected to the inlet portion 31 via a cylindrical connecting member 10. In this way, the water supply system 300 is connected to the inlet hole 90h.
[0014] A horizontally elongated lighting device 60 and a horizontally elongated lighting cover 70 are attached to the second body 40. The second body 40 is assembled to the first body 30 from above and connected by screws or the like. Between the first body 30 and the second body 40, a horizontally elongated storage chamber 91, a horizontally elongated throttling channel 92, and a horizontally elongated discharge port 93 are formed. An inlet hole 90h is connected to the bottom surface of the storage chamber 91. A support column 34 for passing the aforementioned screws is provided protruding from the first body 30. The support column 34 passes through the storage chamber 91. The throttling channel 92 is connected to the side of the storage chamber 91 on the side facing the bathtub 200. The throttling channel 92 has a smaller cross-sectional area than the storage chamber 91. The discharge port 93 is connected to the end of the throttling channel 92 on the side facing the bathtub 200.
[0015] In this embodiment, the lid 50 is a molded product made of resin or the like, but it may be made of other materials. Specifically, for example, the lid 50 may be formed by welding together a plurality of divided parts. Alternatively, for example, the lid 50 may be made of metal or the like. Similarly, the first body 30 and the second body 40 may also be molded products made of resin or the like, or they may be made of other materials.
[0016] As shown in Figure 5, the flow path 90 has, in order from the upstream side, an inlet hole 90h, a storage chamber 91, a throttling flow path 92, and a discharge port 93. Hereinafter, the flow direction in the throttling flow path 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.
[0017] In this embodiment, the three components, the first body 30, the second body 40, and the lid 50, 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.
[0018] "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.
[0019] "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.
[0020] "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.
[0021] "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.
[0022] 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 portion of the upper wall of the storage chamber 91 other than the portion formed by the lid 50, the upper wall of the throttling channel 92, and the upper wall of the discharge port 93. 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.
[0023] The lid 50 constitutes the upper wall portion of the storage chamber 91. Specifically, the lid 50 constitutes most of the ceiling wall of the storage chamber 91 and most of the side wall on the side opposite to the bathtub side at the top of the storage chamber 91. The lateral dimensions of the lid 50 are preferably more than half, and more preferably more than 70%, of the lateral dimensions of the flow path 90, in order to sufficiently improve the maintainability of the flow path 90.
[0024] When hot water W is supplied from the water supply system 300 to the inlet hole 90h, the hot water W flows from the inlet hole 90h into the horizontally elongated storage chamber 91 and spreads laterally. Subsequently, the hot water W passes through the horizontally elongated throttling channel 92 and is discharged from the horizontally elongated discharge port 93 in a horizontally elongated film shape.
[0025] As shown in Figure 6, a water-sealing packing P is provided between the first body 30 and the lid 50. Similarly, water-sealing packings (not shown) are provided between the first body 30 and the second body 40, and between the second body 40 and the lid 50. The lighting device 60 illuminates the hot water W discharged from the outlet 93.
[0026] 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 fixing the water discharge device 1A to the upper edge 210 of the bathtub 200.
[0027] The configuration and effects of this embodiment are summarized below.
[0028] The cover 50 is attached to the body 28 in such a manner that it can be removed from the body 28 while the body 28 remains attached to the edge, and it constitutes a part of the wall of the flow path 90. Therefore, by removing the cover 50 from the body 28, an opening communicating with the flow path 90 can be formed while the body 28 remains attached to the upper edge 210 of the bathtub 200. This makes it easier to clean and perform maintenance, such as cleaning, deep inside the flow path 90.
[0029] The cover 50 forms the wall portion of the flow path 90 other than the discharge port 93, but does not form the wall portion of the discharge port 93. Therefore, there is no need to worry that the dimensions or shape of the discharge port 93 will change depending on how the cover 50 is attached to the body 28, causing a deviation from the intended water discharge state.
[0030] 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. Therefore, the hot water W can be leveled laterally in the storage chamber 91 before being discharged from the discharge port 93, making it easy to form a smooth film of hot water W.
[0031] The lid 50 forms part of the wall of the storage chamber 91. Therefore, the storage chamber 91, which is the furthest from the discharge port 93 and would normally be the most difficult to maintain, can be made easier to maintain. Specifically, the lid 50 forms the ceiling wall of the storage chamber 91. Therefore, the storage chamber 91 can be maintained from the ceiling side. Furthermore, the lid 50 forms the side wall of the storage chamber 91 on the side opposite to the bathtub 200. Therefore, the storage chamber 91 can also be maintained from the side opposite to the bathtub 200.
[0032] The cover 50 extends laterally. Therefore, by removing the cover 50 from the body 28, the horizontally elongated flow path 90 can be efficiently maintained.
[0033] The body 28 is formed in multiple sections. Therefore, it is easy to mold the body 28, even if the shape of the flow path 90 is complex.
[0034] Other embodiments are described below. The following embodiments will be described based on the designated embodiment, focusing on the differences, and explanations of aspects that are the same as or similar to the designated embodiment will be omitted as appropriate.
[0035] [Second Embodiment] The water discharge device 1B of the second embodiment will be described based on the first embodiment. As shown in Figures 7 and 8, the body 28 is not divided into a first body 30 and a second body 40. In other words, the body 28 is a single, integrated component, and the body 28 and the lid 50 form the entire wall of the flow path 90. In this embodiment, a portion of the body 28 in the first embodiment belongs to the lid 50. Specifically, the portion that forms the side wall on the side opposite to the bathtub 200 in the lower part of the storage chamber 91 belongs to the lid 50.
[0036] According to this embodiment, since the body 28 is a single component, the number of parts in the water discharge device 1B can be reduced compared to the case where there are two components. Even though the body 28 is a single component, in this embodiment the lid 50 includes a part of the body 28 in the first embodiment, so molding the body 28 does not become extremely difficult. Since the body 28 is a single component, the need to connect the first body 30 and the second body 40 with screws or the like is eliminated, and the support column 34 shown in Figure 4 can be omitted. Therefore, the structure of the body 28 can be simplified.
[0037] [Third Embodiment] The water discharge device 2A of the third embodiment will be described based on the first embodiment. As shown in Figure 10, which is an exploded view of the water discharge device 2A of Figure 9, the water discharge device 2A has a horizontally elongated base plate 20 and a horizontally elongated flow straightening valve 35. In this embodiment, there is one inlet 31, but there may be two or more.
[0038] The base plate 20 is interposed between the upper edge 210 of the bathtub 200 and the first body 30. The base plate 20 has a cylindrical base projection 21 that fits onto the inlet 31 of the first body 30. The downstream end of the second water supply pipe 304 is connected to the base projection 21 via a connecting member 10. In this way, the water supply system 300 is connected to the inlet hole 90h via the base plate 20 and the connecting member 10.
[0039] The flow straightening fin 35 is installed in the storage chamber 91. Hereinafter, the part of the storage chamber 91 located below the flow straightening fin 35 will be referred to as the "lower chamber of the storage chamber 91," and the part of the storage chamber 91 located above the flow straightening fin 35 will be referred to as the "upper chamber of the storage chamber 91." The flow straightening fin 35 has flow straightening holes 36 that penetrate vertically and are arranged horizontally.
[0040] As shown in Figures 11 and 12, 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 straightened by passing through the rectifying holes 36 which are arranged in parallel in the laterally direction. As a result, in this embodiment, the hot water W is more easily distributed evenly in the laterally direction than in the first embodiment.
[0041] [Fourth Embodiment] Next, the water discharge device 2B of the fourth embodiment will be described based on the previous third embodiment. Similar to the second embodiment, as shown in Figures 13 and 14, the body 28 is a single component. According to this embodiment, in addition to the configuration and effects of the third embodiment, such as easier distribution of hot and cold water W in the lateral direction, the configuration and effects of the second embodiment, such as a reduction in the number of parts, can be achieved.
[0042] [Fifth Embodiment] The water discharge device 3A of the fifth embodiment will be described based on the third embodiment, two embodiments prior to this one. As shown in Figures 15 and 16, the water discharge device 3A has two neck members 80 arranged side by side in the left-right direction. Each neck member 80 has a second flow path 89 on its inside and a cylindrical second inlet protruding downward. A second connecting member 18 is fitted onto the second inlet. The inside of the second inlet constitutes the upstream portion of the second flow path 89. The downstream portion of the second water supply pipe 304 branches into three, two of which are connected to the second inlet via the second connecting member 18. In this way, the water supply system 300 is connected to each second flow path 89. The downstream end of the second flow path 89 constitutes a second discharge port. When hot water is supplied to the second inlet, which is the upstream end of the second flow path 89, the hot water W is discharged from the second discharge port, which is the downstream end of the second flow path 89, towards the neck of the bather.
[0043] As shown in Figure 17, in this embodiment, the flow straightening valve 35 is configured to guide the hot water W to the upper part of the upper chamber of the storage chamber 91. As a result, the hot water W is guided to one end at the upper part of the upper chamber and then returns to the lower part of the upper chamber. This lengthens the flow path 90 to improve the flow straightening performance and avoids interference between the flow path 90 and the second flow path 89.
[0044] According to this embodiment, in addition to improving the rectification performance, it is possible to discharge hot water to the neck of the bather.
[0045] [Sixth Embodiment] The water discharge device 3B of the sixth embodiment will be described based on the previous fifth embodiment. Similar to the second embodiment, as shown in Figure 18, the body 28 is a single component. According to this embodiment, in addition to the configuration and effects of the fifth embodiment, such as being able to discharge hot water W towards the bather's neck, the configuration and effects of the second embodiment, such as being able to reduce the number of parts, can be realized.
[0046] [Change form] The embodiments described above can be implemented with modifications as follows, for example. As shown in Figure 19, the dimensions of the lid 50 may be reduced so that the lid 50 constitutes only the ceiling wall of the storage chamber 91. In this case, the body 28 constitutes the entire side wall of the storage chamber 91 on the side opposite to the bathtub 200. As shown in Figure 20, the lateral dimensions of the lid 50 may be less than half the lateral dimensions of the flow path 90. These embodiments can be suitably adopted when it is important to keep the dimensions of the lid 50 small rather than the maintainability of the flow path 90. [Explanation of symbols]
