[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a lighting storage structure and a toilet apparatus according to an embodiment of the present disclosure will be described with reference to the drawings.

[0011] As shown in Figures 1 and 2, the toilet device 1 according to this embodiment comprises a toilet body 10 having a toilet bowl 11, a toilet seat 2 provided so as to be openable and closable relative to the toilet body 10, and a toilet lid (not shown) provided so as to be openable and closable relative to the toilet seat 2. Figure 1 shows the toilet seat 2 in a closed state.

[0012] In the following description, when a user of the toilet device 1 is seated on the toilet seat 2, the front side of the user is defined as the front side, and the back side of the user is defined as the rear side, and the direction connecting the front side and the rear side is defined as the front-to-back direction X1, and the direction connecting the left side and right side as seen by the user of the toilet seat 2 is defined as the left-to-right direction X2. The side away from the floor surface on which the toilet device 1 is installed is defined as the "upper side", the side closer to the floor surface is defined as the "lower side", and the direction connecting the upper side and the lower side is defined as the up-down direction X3.

[0013] The toilet body 10 has a toilet bowl 11. At the rear of the toilet body 10, a functional section 3 is provided which houses the toilet seat 2, a mechanism for opening and closing the toilet lid, a control device for controlling water use, etc.

[0014] As shown in Figures 2 and 3, the toilet body 10 comprises a toilet bowl 11 and a water pooling section 12 located below the toilet bowl 11. The toilet bowl 11 has a waste receiving surface 13, a rim section 15 located above the waste receiving surface 13, and a shelf section 16 located between the waste receiving surface 13 and the rim section 15. The rim section 15 has a side surface 15a and a top surface 15b. At the rear of the toilet body 10, the top surface 15b of the rim section 15 is set to have a smaller width in the front-to-rear direction Y than the shelf section 16 (see Figure 4). The toilet seat 2 is disposed on the top surface 10a of the toilet body 10. The water pooling section 12 is connected to a toilet drainage channel 17 for discharging waste and the like from the toilet bowl 11.

[0015] The toilet seat 2 is accommodated in the functional part 3 located at the rear of the toilet body 10 and is provided so as to be rotatable about a toilet seat rotation shaft 31 (see Figs. 1 and 2) extending in the left-right direction X2, and is provided so as to be rotatable between a closed position covering the upper surface 10a of the toilet body 10 and an open position standing upright relative to the toilet body 10. The toilet seat 2 is annular and extends continuously in the circumferential direction, and a user can sit on it when it is placed on the upper surface 10a of the toilet body 10 in the closed position. The toilet seat 2 is preferably made of a material having higher rigidity than polypropylene, such as polybutylene terephthalate (PBT resin), ABS, or urea resin. It is also possible to use a material in which the rigidity is increased by adding additives such as glass fiber or talc to polypropylene, or polypropylene is reinforced with a metal plate.

[0016] 1, the toilet seat 2 has a pair of toilet seat support parts 21A, 21B that extend rearward from both the left and right ends of the rear end when in the closed position and are rotatably connected to the functional part 3. The pair of toilet seat support parts 21A, 21B are provided with corresponding rotation hinge parts, respectively.

[0017] The functional unit 3 is located at the rear of the toilet body 10, and is configured so that it is possible to incorporate, for example, a cleaning function (warm water cleaning toilet seat), a heater function (heated toilet seat), a deodorizing function, a disinfecting function, a drying function, a toilet seat opening / closing function, a toilet lid opening / closing function, an onomatopoeic function, etc. within the main body case 32 described below.

[0018] 2, the functional unit 3 includes a main body case 32, a cover 33 that covers an upper opening of the main body case 32, and a toilet seat rotation shaft 31 that is rotated by a motor unit (not shown) housed in the main body case 32 and supports the toilet seat 2 so that it can be opened and closed. The functional unit 3 is supported on a base plate 14 provided at the upper rear part of the toilet body 10.

[0019] 3, the functional section 3 includes a local cleaning device 4 having a local cleaning nozzle 40 (water-discharging nozzle) for cleaning the local areas after use, for example, by a user operating a remote control, and is provided in a state of being fixed to a base plate 14. The base plate 14 is formed into a plate shape, for example, by resin molding or the like.

[0020] As shown in Fig. 4, the genital washing nozzle 40 advances and retreats between the inside of the toilet body 10 and the main body case 32 through the nozzle opening in response to remote control operation or the like. The genital washing nozzle 40 is formed in a substantially cylindrical rod shape and is supported by an appropriate advancing and retreating mechanism so that it can advance and retreat along the nozzle central axis. The tip of the genital washing nozzle 40 is covered by a tip cover 41 having a nozzle opening 41a. The nozzle opening 41a is a substantially circular opening large enough that the genital washing nozzle 40 can be inserted therethrough when the genital washing nozzle 40 advances forward.

[0021] A horizontally long strip-shaped shutter 42 that opens and closes the nozzle opening 41a is provided at the front end of the base plate 14. When the shutter 42 is in the lower position, the nozzle opening 41a is closed.

[0022] The shutter 42 is provided to prevent, for example, dirt, splashes of cleaning water, and the like from getting onto the local pubic cleaning nozzle 40 or from entering the inside of the base plate 14. The shutter 42 is opened when the local pubic cleaning nozzle 40 advances by a shutter operating mechanism (not shown) that works in conjunction with the advancing movement of the local pubic cleaning nozzle 40. On the other hand, when the local pubic cleaning nozzle 40 retreats into the base plate 14 through the nozzle opening 41a, the pressed state of the shutter 42 is released and the shutter 42 automatically rotates, causing the nozzle opening 41a to be closed by the shutter 42.

[0023] As shown in Fig. 4, the portion of the base plate 14 below the local cleansing device 4 is provided with a partition 14A having a space for accommodating a deodorizing unit 34 having a deodorizing cartridge. The partition 14A has a front end wall 141 (front end of the partition), a rear end wall 142, and a bottom wall 143, and has an opening at the top. The bottom wall 143 extends obliquely upward from the lower end of the front end wall 141 toward the lower end of the rear end wall 142. A circular irradiation hole 143a that serves as an irradiation part of the lighting device 6 described later is formed in the front part of the bottom wall 143. The dimensions of the irradiation hole 143a are set to a size that allows a light irradiation part 61 described later to fit into it.

[0024] An upper opening of the partition 14A is covered by a cover body 5. In the space within the partition 14A, the deodorizing unit 34 is housed with a gap (lighting arrangement space S1) above the bottom wall 143. A lighting device 6 is disposed in front of the lighting arrangement space S1.

[0025] The cover body 5 is disposed between the partition section 14A of the base plate 14 and the local cleaning device 4. The cover body 5 has a visor section 51 extending forward from an upper portion of the rear end wall 142 of the base plate 14, a front inclined section 52 extending diagonally downward and forward from the visor section 51, and a cover front end section 53 extending downward from the front end of the front inclined section 52. The local cleaning nozzle 40 of the local cleaning device 4 is disposed above the cover body 5.

[0026] The cover front end 53 is disposed with a gap S2 in front of the front end wall 141 located in front of the partition 14A. The dimension of this gap S2 is set to about 3 mm, for example. Water on the eaves portion 51 of the cover body 5 flows down the eaves portion 51 and the front inclined portion 52 and falls into the toilet bowl 11 in front of the partition 14A of the base plate 14.

[0027] The lighting device 6 has a light main body 60, a light irradiation section 61 for emitting light L, and a connection section 62 for supplying electricity to the light irradiation section 61 in the light main body 60.

[0028] The lighting device 6 is stored in the lighting arrangement space S1 with the light irradiation unit 61 facing forward. At this time, the lighting device 6 is provided on the bottom wall 143 of the base plate 14, and is arranged in an inclined position so that the light irradiation unit 61 is located lower than the wiring unit 62, that is, in a position in which the light irradiation unit 61 side faces diagonally downward.

[0029] A power cable 63 connected to the wire connection portion 62 passes through a rear gap within the partition portion 14A, extends from above the rear end wall 142 to the rear of the base plate 14, and is connected to a power supply portion (not shown).

[0030] The light irradiation section 61 is formed in a cylindrical shape and protrudes downward from the front lower surface of the light body section 60. The light irradiation section 61 is provided with a waterproof packing 65 between the irradiation hole 143a formed in the bottom wall 143 of the base plate 14 and the wiring section 62. The irradiation port 61a of the light irradiation section 61 is arranged so as to irradiate light downward. The waterproof packing 65 is provided in a liquid-tight state by extending along the entire outer circumferential surface of the light body 60, and is provided in a liquid-tight state against the outer circumferential surface of the light irradiation section 61. For example, a sponge or the like can be used as the material for the waterproof packing 65.

[0031] As shown in Fig. 4, the light irradiation unit 61 is exposed forward of the top surface 15b of the rim portion 15 located at the rear of the toilet body 10 when viewed from below. The irradiation port 61a of the light irradiation unit 61 is installed so that the emitted light L irradiates the shelf portion 16 of the toilet bowl 11. More specifically, the light irradiation unit 61 is positioned so as to irradiate the boundary portion between the shelf portion 16 and the rim portion 15.

[0032] Next, the operation of the lighting storage structure and the toilet device 1 according to this embodiment will be described in detail with reference to the drawings.

[0033] As shown in Fig. 4, in the toilet apparatus 1 according to this embodiment, the lighting device 6 is provided in the partition 14A around the private parts washing nozzle 40, and the upper part of the lighting device 6 is covered with the cover body 5, so that it is possible to prevent water sprayed from the private parts washing nozzle 40 from splashing on the lighting device 6. That is, the cover body 5 has an eaves part 51 that covers the upper opening of the partition 14A and a front inclined part 52, so that water splashing on the cover body 5 can drop from the front end of the cover body 5 into the toilet bowl 11. Therefore, even if the lighting device 6 is provided near, for example, the lower part of the private parts washing nozzle 40 of the private parts washing device 4, it is possible to prevent the waste water from the private parts washing nozzle 40 from splashing on and coming into contact with the lighting device 6.

[0034] In this embodiment, a water-tight gasket 65 is provided between the irradiation hole 143a provided in the base plate 14 and the light irradiation section 61 fitted into the irradiation hole 143a, thereby preventing water from inside the toilet bowl 11 from passing through the irradiation hole 143a and entering the lighting arrangement space S1 in which the lighting device 6 is arranged in the partition section 14A.

[0035] In this embodiment, a partition 14A is provided to form a space on the base plate 14, and the cover front end 53 located at the front end of the cover body 5 is positioned with a gap S2 in front of the partition front end (front end wall 141 of partition 14A) located on the front side of the partition 14A, so that it is possible to prevent water from entering the partition 14A due to surface tension, as would occur if the cover front end 53 and the front end wall 141 were in close contact with each other.

[0036] In this embodiment, the lighting device 6 is provided with a connection part 62 that supplies electricity to the light irradiation part 61. The light irradiation part 61 is inclined so as to be located lower than the connection part 62. Therefore, even if water enters the partition part 14A, the water flows from the connection part 62 side to the light irradiation part 61 side, so that the connection part 62 is unlikely to come into contact with water.

[0037] In this embodiment, the lighting device 6 is installed so that the light emitted by it hits the shelf portion 13a that rises from the bowl portion 12 of the toilet bowl 11 to the upper rim 13, so that even if the light L is reflected by the shelf portion 13a, it is in a position where it is difficult for people to see it. In other words, it is possible to prevent the reflected light of the light L that hits the bowl portion 12 of the toilet bowl 11 from easily reaching people's eyes.

[0038] In the lighting storage structure and toilet apparatus 1 according to the present embodiment, the lighting device 6 that illuminates the inside of the toilet bowl 11 can be waterproofed, and problems such as malfunction of the lighting device 6 can be suppressed.

[0039] Although the embodiments of the lighting storage structure and toilet apparatus according to the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments.

[0040] For example, in this embodiment, the lighting device 6 is provided at a position lower than the local cleaning nozzle 40 of the local cleaning device 4. The positional relationship between the lighting device 6 and the local cleaning nozzle 40 is not particularly limited. For example, the lighting device 6 may be provided next to the local cleaning nozzle 40 at approximately the same height. In short, the present invention can be applied to toilet devices configured such that the lighting device 6 is provided in the space around a water-discharging nozzle such as the local cleaning nozzle 40.

[0041] In this embodiment, a waterproof packing 65 is provided between the irradiation hole 143a provided in the base plate 14 and the light irradiation unit 61. This waterproof packing 65 may be omitted.

[0042] In this embodiment, a gap S2 is provided between the cover front end 53 and the partition front end (front end wall 141), but such a gap S2 may be omitted.

[0043] Furthermore, as in the embodiment described above, the lighting device 6 is disposed in an inclined position such that the light irradiation unit 61 is located below the wiring unit 62, but it may be disposed horizontally. The direction of the light L emitted from the light irradiation unit 61 of the lighting device 6 and the irradiation position on the toilet bowl 11 are not limited to the shelf portion 13a of the upper rim 13.

[0044] In addition, the components in the above-described embodiments can be replaced with well-known components as appropriate without departing from the spirit of the present disclosure. [Explanation of symbols]
