[0009] (Bathroom unit configuration) As shown in Figure 1, bathroom unit 1 is defined by wall surface 4, floor surface 5, and ceiling surface 6 that surround bathroom 2. In addition to wall surface 4, floor surface 5, and ceiling surface 6, bathroom unit 1 also includes a bathtub 8, a shower device 10, and a seat portion 12.
[0010] The bathtub 8 stores water for the user to bathe in. In this specification, it is referred to as "water" regardless of the temperature. The bathtub 8 stores water supplied from a water supply port (not shown). The bathtub 8 is located at one end of the bathroom 2. Next to the bathtub 8, there is a space for using the shower device 10. Next to the bathtub 8, there is a seat 12 on which the user sits when using the shower device 10. The top surface of the seat 12 has a generally flat shape to make it easy for the user to sit on.
[0011] A shower unit 10 is disposed on the opposite side of the seat unit 12 from the bathtub 8. The shower unit 10 is disposed along a wall surface 4 located on the opposite side from the bathtub 8. The shower unit 10 includes a hand shower unit 20, an overhead shower unit 30, and an operating unit 100.
[0012] Hand shower unit 20 comprises shower head 22, hose 24, and head holding member 26. Shower head 22 is connected to a water supply source such as a water heater via hose 24. Shower head 22 discharges water supplied via hose 24 from multiple outlets. Shower head 22 is held by head holding member 26. Head holding member 26 is fixed to wall surface 4. Head holding member 26 holds shower head 22 in a manner that allows the user to remove it. The user can use shower head 22 while it is held by head holding member 26. The user can remove shower head 22 from head holding member 26 and use it while holding it in their hand.
[0013] As shown in Figures 2 and 3, the overhead shower unit 30 includes a head body 32, a light source 34, and suppression units 36 and 38. The head body 32 is attached to the ceiling surface 6 and has a rectangular shape with rounded corners. The head body 32 includes a surface plate 40, a shower unit 44, a mist unit 46, and a pouring water unit 48. The surface plate 40 is exposed downward from the ceiling surface 6 and has a rectangular shape with rounded corners. In a modified example, the surface plate 40 may have a shape other than a rectangular shape. For example, the surface plate 40 may be circular, elliptical, or a polygonal shape other than a rectangular shape.
[0014] A shower section 44, a mist section 46, and a pouring water section 48 are attached to the surface plate 40. The shower section 44 includes a plurality of outlets 54 and a path (not shown). The plurality of outlets 54 have openings for discharging water. The plurality of outlets 54 are arranged penetrating the surface plate 40. The plurality of outlets 54 are arranged at intervals from one another. The plurality of outlets 54 discharge water in shower form. Specifically, in shower form, water droplets having a particle size of approximately 0.5 mm to 3.0 mm are continuously discharged from each outlet 54. The plurality of outlets 54 communicate with the path. The path is connected to a water supply source.
[0015] The cascading water section 48 has one outlet 58 and a path 59. One outlet 58 is disposed so as to penetrate the surface plate 40. The outlet 58 has an opening for discharging water. The outlet 58 is disposed in the center of the head body 32. The hole diameter of the outlet 58 is larger than the hole diameters of the outlets 54 and 56. By employing outlets 54, 56, and 58 with different hole diameters in one head body 32, different types of water discharges and different types of water discharges can be used. The outlet 58 discharges water in the cascading water state. In the cascading water state, water is continuously discharged from the outlet 58 in a waterfall-like manner. The outlet 58 communicates with the path 59. The outlet 58 and the path 59 are defined by a supply pipe 60. The supply pipe 60 is attached to the surface plate 40. The supply pipe 60 is made of engineering plastic, such as acrylonitrile butadiene styrene resin (i.e., ABS resin) or polypropylene. The path 59 extends in the vertical direction. The discharge port 58 is disposed at the lower end of the path 59. Although an example in which one discharge port 58 is provided is illustrated, a plurality of discharge ports 58 may be provided in the head main body 32. The arrangement of the discharge ports 58 in the head main body 32 is not particularly limited. The discharge port 58 may be provided in a position other than the center of the head main body 32. Furthermore, for example, a plurality of discharge ports 58 may be provided symmetrically.
[0016] The mist section 46 includes a plurality of outlets 56 and a path 57. The plurality of outlets 56 are disposed through the surface plate 40. Each of the outlets 56 has an opening for discharging water. The plurality of outlets 56 are disposed at intervals around the outlet 58. The diameter of the outlets 56 is smaller than the diameter of the outlet 54. The plurality of outlets 56 discharge water in a mist state. Specifically, in the mist state, water droplets having a particle diameter of approximately 100 μm to 350 μm are sprayed in a mist form from each outlet 56. The outlets 56 communicate with the path 57. The outlets 56 and the path 57 are defined by a water supply member 62. The water supply member 62 is attached to the surface plate 40. The water supply member 62 has a cylindrical shape that surrounds the outlets 58 and the supply pipe 60. The water supply member 62, like the supply pipe 60, is made of, for example, resin. The path 57 extends in the vertical direction. The outlet 56 is disposed at the lower end of the path 59. The number of outlets 56 disposed in the mist section 46 is not particularly limited. For example, the mist section 46 may have one outlet 56. The head body 32 may not have an outlet 56. In this case, a mechanism for changing the aperture diameter of one or more of the multiple outlets 54 may be provided. The shower state and the mist state may be switched by changing the aperture diameter of one or more outlets 54.
[0017] The outlets 54, 56, and 58 are different types of outlets. For example, if one of the outlets 54 and 56 is a first type of opening, the outlet 58 is a second type of opening.
[0018] A switching valve device (not shown) is arranged between the water supply source and each of the shower section 44, mist section 46, and pouring water section 48. The switching valve device switches the water supply destination between the shower section 44, mist section 46, and pouring water section 48. After the pouring water section 48 has finished, water remains in the path 59.
[0019] A cylindrical space 64 is formed between the supply pipe 60 and the water supply member 62. The light source 34 is arranged in the space 64. The light source 34 is arranged between the outlet 58 and the plurality of outlets 56. The light source 34 is arranged around the outlet 58. The light source 34 includes a plurality of LEDs. In FIG. 4, the light source 34 is shown hatched. In reality, the LEDs are arranged. The plurality of LEDs are arranged at equal intervals around the outlet 58. Power is supplied to the light source 34 via wiring (not shown).
[0020] The suppression unit 36 is disposed between the light source 34 and the discharge port 58. The suppression unit 36 has a cylindrical shape that surrounds the discharge port 58 on the outer periphery of the discharge port 58. The suppression unit 36 is sandwiched between the light source 34 and the supply pipe 60. The suppression unit 38 is disposed between the light source 34 and the plurality of discharge ports 56. The suppression unit 38 has a cylindrical shape that surrounds the light source 34 on the outer periphery of the light source 34. The suppression unit 38 is sandwiched between the light source 34 and the water supply member 62.
[0021] The suppression portions 36, 38 are made of a heat insulating material. The heat insulating material is made of a material with lower thermal conductivity than the resin material used to make the head body 32. The heat insulating material is, for example, a foamed plastic material such as rigid polyurethane foam or polyethylene foam. The heat insulating material is not particularly limited. For example, it may be an inorganic porous material such as calcium silicate.
[0022] The light source 34 is switched on and off automatically or by operation of the operation unit 100. For example, the light source 34 may be turned on when the pouring water section 48 is used. The light source 34 may be turned off by switching from the pouring water section 48 to either the shower section 44 or the mist section 46. For example, the light source 34 may be turned on when a user is detected by a human presence sensor. The light source 34 may be turned off when a user is not detected by the human presence sensor.
[0023] By arranging the light sources 34 around the outlets 56, 58, it is possible to irradiate the water being discharged from the outlets 56, 58 with light. By arranging multiple LEDs at equal intervals around the outlet 58, it is possible to evenly irradiate the water being discharged from the outlet 58 with light. This improves the design. In a modified example, it is not necessary to arrange the multiple LEDs at equal intervals. The light sources 34 may be arranged asymmetrically around the outlets 56, 58. In this case as well, it is possible to irradiate the water being discharged from the outlets 56, 58 with light, thereby improving the design.
[0024] When power is supplied to the light source 34 and it is turned on, the light source 34 generates heat. In other words, the light source 34 is a heat source. A suppression unit 36 is arranged between the light source 34 and the outlet 58. This can suppress the heat from the light source 34 from being transferred to the water remaining in the path 59 surrounded by the light source 34. In other words, it can reduce the thermal conductivity between the light source 34 and the outlet 58. When water is discharged from the cascading water section 48, the water in the path 59 is discharged. This can suppress the heat from the light source 34 from increasing the temperature of the initial water discharged from the cascading water section 48. The suppression unit 36 surrounds the light source 34 from the outside. A suppression unit 36 is arranged between the light source 34 and the outlet 56. This can suppress the heat from the light source 34 from increasing the temperature of the water discharged from the outlet 56.
[0025] (Second embodiment) Differences from the first embodiment will be described with reference to FIG. 4. Components identical to those in the first embodiment are designated by the same reference numerals, and a description thereof will be omitted. In the overhead shower unit 130 of this embodiment, air layers 136, 138 are disposed instead of the suppression units 36, 38. The air layer 136 is disposed between the light source 34 and the outlet 58. Similar to the suppression unit 36, the air layer 136 has a cylindrical shape surrounding the outlet 58 on the outer periphery of the outlet 58. The air layer 136 is sandwiched between the light source 34 and the supply pipe 60. The air layer 138 is disposed between the light source 34 and the plurality of outlets 56. Similar to the suppression unit 38, the air layer 138 has a cylindrical shape surrounding the light source 34 on the outer periphery of the light source 34. The air layer 138 is sandwiched between the light source 34 and the water supply member 62.
[0026] According to this configuration, the air layers 136, 138, like the suppression sections 36, 38, can suppress the transfer of heat from the light source 34 to the outlets 56, 58. In other words, the thermal conductivity between the light source 34 and the outlet 58 can be reduced.
[0027] In a variant, one of the air layers 136, 138 may replace one of the suppressors 36, 38. The air layers 136, 138 and the suppressors 36, 38 may be arranged together.
[0028] (Third embodiment) Differences from the first embodiment will be described with reference to FIG. 5. Components identical to those in the first embodiment are assigned the same reference numerals, and descriptions thereof will be omitted. In the overhead shower unit 230 of this embodiment, a plurality of heat dissipation fins 235 are arranged above the light source 34. The plurality of heat dissipation fins 235 are arranged at equal intervals on the upper end surface of the light source 34. The heat dissipation fins 235 have a flat plate shape. The heat dissipation fins 235 may have a shape other than a flat plate, such as a curved plate shape. The heat dissipation fins 235 are made of a material with high thermal conductivity, such as aluminum or copper. The upper end of the heat dissipation fins 235 is exposed to the atmosphere. This allows heat from the light source 34 to be dissipated to the atmosphere via the heat dissipation fins 235.
[0029] In a modified example, at least one of the air layers 136, 138 may be arranged instead of at least one of the suppression units 36, 38. At least one of the suppression units 36, 38 and the air layers 136, 138 may not be arranged. At least three or more of the suppression units 36, 38 and the air layers 136, 138 may not be arranged.
[0030] (Fourth embodiment) Differences from the first embodiment will be described with reference to Figure 6. Components that are the same as those in the first embodiment are given the same reference numerals and will not be described again. The overhead shower unit 330 of this embodiment has a through-hole 262 in the water supply member 62 that communicates with the path 59. The through-hole 262 connects the path 59 with the atmospheric layer outside the water supply member 62. This configuration makes it possible to prevent water from accumulating in the path 59 after the cascading water unit 48 has finished. It is also possible to prevent the temperature of the water accumulating in the path 59 from increasing due to the heat from the light source 34.
[0031] In a modified example, at least one of the suppression units 36, 38 may be replaced with at least one of the air layers 136, 138. At least one of the suppression units 36, 38 and the air layers 136, 138 may not be provided. A plurality of heat dissipation fins 235 may be provided. At least three or more of the suppression units 36, 38 and the air layers 136, 138 may not be provided.
