The following describes the embodiments. Identical components are given the same reference numerals, and duplicate explanations are omitted. In each drawing, components are omitted, enlarged, or reduced as appropriate for the sake of convenience. The drawings should be viewed according to the orientation of the reference numerals. In this specification, "attachment" includes cases where the conditions mentioned are met directly by two parties, as well as cases where the conditions are met via other members, unless otherwise specified.

Refer to Figures 1 and 2. The toilet device 10 comprises a toilet body 12 and a casing 14 mounted to the rear of the toilet body 12.

The material of the toilet body 12 is, for example, ceramic. The material of the toilet body 12 is not particularly limited, and may be, for example, resin. In this diagram, detailed internal structure of the toilet body 12 is omitted.

The toilet body 12 includes a toilet bowl 16. The following description will use the circumferential and radial directions of the toilet bowl 16. The "circumferential direction" refers to the direction going around the center CL of the upper end opening 16a of the toilet bowl 16 in a plan view. The "radial direction" refers to the direction perpendicular to the vertical line passing through the center CL.

The toilet bowl portion 16 comprises a waste receiving surface 18 that receives waste, and a rim portion 20 that forms the upper end portion of the toilet bowl portion 16 in the range above the outer peripheral end portion 18a of the waste receiving surface 18. The waste receiving surface 18 comprises a shelf surface 22 that receives the main flush water flow Fa, which will be described later, and guides it in the swirling direction Da. The shelf surface 22 is provided in a portion of the range extending radially inward from the outer peripheral end portion 18a of the waste receiving surface 18.

The rim portion 20 has a rising surface 24 rising from the outer peripheral end 18a of the waste receiving surface 18. The rising surface 24 is a surface that, in a cut surface along the radial direction, forms an angle of 45° or more with respect to the horizontal plane over the entire range from the lower inflection point 24a to the upper inflection point 24b. The inflection points 24a and 24b here include, for example, a boundary between a pair of curves with different curvatures, a boundary between a curve and a straight line, etc. In this embodiment, the lower inflection point 24a is provided at the outer peripheral end 18a of the waste receiving surface 18, and the upper inflection point 24b is provided at the upper end opening 16a of the toilet bowl 16. The rising surface 24 of this embodiment continues to the upper end opening 16a of the toilet bowl 16, and does not have a sloping portion that slopes radially inward as it moves upward over the entire range in the vertical direction Z. In addition, the rising surface 24 may have at least a portion that slopes radially inward as it moves upward. Additionally, the rim portion 20 may have an overhang portion that protrudes radially inward from the rim portion 20.

The toilet body 12 comprises a toilet drainage channel 26 connected to the bottom of the toilet bowl 16, and an upper surface 28 where the upper end opening 16a of the toilet bowl 16 opens. The toilet drainage channel 26 is connected to a drain pipe (not shown) installed in the building. The toilet drainage channel 26 serves as a passageway for waste and the like that is discharged from inside the toilet bowl 16 to the drain pipe. A recess 28a is provided in the upper surface 28 behind the toilet bowl 16. A part of the casing 14 is housed in the recess 28a.

The toilet device 10 includes a main water discharge section 30 that supplies flushing water into the toilet bowl 16. In this embodiment, the main water discharge section 30 is provided in the toilet bowl body 12 as a part of the toilet bowl body 12. The main water discharge section 30 includes a main water discharge hole 32 that opens on the inner peripheral surface of the toilet bowl 16, and a water passage 34 that supplies flushing water supplied from a first main water passage 62 (described later) to the main water discharge hole 32. The main water discharge section 30 discharges flushing water from the main water discharge hole 32 into the toilet bowl 16, thereby forming a main flushing water flow Fa that swirls within the toilet bowl 16. In FIG. 1, an arrow indicates the main flow direction of the main flushing water flow Fa. The main flushing water flow Fa cleans the toilet bowl 16, and waste within the toilet bowl 16 is discharged through the toilet drainage passage 26.

The casing 14 is provided as part of a functional device separate from the toilet seat (not shown). The casing 14 is attached to the toilet body 12 using screws or the like. The casing 14 houses internal equipment (not shown). The internal equipment is, for example, at least one of a private parts cleansing device, a drying device, a deodorizing device, a water supply device, a foam supply device, etc.

Please refer to Figures 3 and 4. Figure 4 is also a view of a portion of the casing 14 from the view point Va in Figure 1. The casing 14 includes a plate-shaped base portion 36 that constitutes the lower wall portion of the casing 14, and a cover portion 38 that is disposed above the base portion 36 and covers the internal equipment on the base portion 36.

The toilet device 10 is equipped with auxiliary water discharge sections 40A, 40B that supply flushing water into the toilet bowl 16. In this embodiment, the auxiliary water discharge sections 40A, 40B include a first auxiliary water discharge section 40A and a second auxiliary water discharge section 40B. The multiple auxiliary water discharge sections 40A, 40B are provided at locations spaced apart in the circumferential direction of the toilet bowl 16. Each auxiliary water discharge section 40A, 40B is provided in the casing 14. The auxiliary water discharge sections 40A, 40B are provided separately from the toilet body 12. In a plan view, the auxiliary water discharge sections 40A, 40B are positioned radially inward of the upper end opening 16a of the toilet bowl 16 (see FIG. 1).

The casing 14 has a water receiving section 42 that receives the water W discharged from the downstream end of the sub-channel 70, which will be described later. The water receiving section 42 is a recess that is recessed downward on the inner lower surface of the base section 36. The water receiving section 42 has a first wall section 42a that first receives the water W discharged from the sub-channel 70, and a second wall section 42b that is continuous with the first wall section 42a. The second wall section 42b is inclined downward toward the front. A nozzle (not shown) of the local cleaning device is disposed above the second wall section 42b. The front end of the second wall section 42b forms an opening that is opened and closed by a shutter, and the nozzle can advance and retreat through the opening.

Refer to Figures 3 to 6. The first auxiliary water discharge section 40A has a first auxiliary water discharge hole 44A provided in the first wall portion 42a of the casing 14. The second auxiliary water discharge section 40B has a second auxiliary water discharge hole 44B provided in the second wall portion 42b of the casing 14. Each auxiliary water discharge hole 44A, 44B is provided as a through hole that passes through the base portion 36 of the casing 14 in the vertical direction. Each auxiliary water discharge hole 44A, 44B is a slit that extends in the circumferential direction of the toilet bowl portion 16. This means that the main longitudinal component of the elongated slit is the circumferential direction, not the radial direction.

Each auxiliary water discharge section 40A, 40B has a rib-shaped guide section 46 that protrudes downward from the radially inward and lower inner edge of the auxiliary water discharge hole 44A, 44B. The guide section 46 is provided so as to extend radially outward. In this embodiment, the guide section 46 is provided so as to extend downward as it moves radially outward.

The first auxiliary water discharge section 40A has a rib-shaped damming section 48 that protrudes upward from the radially inward and upper inner edge of the first auxiliary water discharge hole 44A. The damming section 48 can block the water W that flows downward in the second wall section 42b and guide the water W to the first auxiliary water discharge hole 44A. The first auxiliary water discharge section 40A has a rib section 50 that protrudes downward from the radially outward and lower outer edge of the first auxiliary water discharge hole 44A.

Please refer to Figures 5 to 7. In Figure 7, an arrow indicates the main flow direction of the water W discharged from the secondary water channel 70. The water W discharged from the secondary water channel 70 is received by the water receiving portion 42. The water received on the water receiving portion 42 flows toward each of the secondary water discharge holes 44A, 44B, and is supplied to each of the secondary water discharge holes 44A, 44B. In this process, the water on the second wall portion 42b flows downward according to the gradient of the second wall portion 42b.

Water supplied to the secondary water discharge holes 44A, 44B from the upstream side is discharged from the secondary water discharge holes 44A, 44B. As a result, the secondary water discharge sections 40A, 40B supply a continuous water flow into the toilet bowl 16 as the secondary flushing water flow Fb. Here, "continuous water flow" does not mean a mist consisting of multiple water droplets made by breaking down water into small particles, but a continuous, single body of water flow. The condition for "continuous water flow" only needs to be met immediately before the water leaves the secondary water discharge sections 40A, 40B, and the water may be divided due to the influence of surface tension, etc. after leaving the secondary water discharge sections 40A, 40B.

The guide portion 46 in this embodiment is continuous with the inner surface on the radially inner side of the auxiliary water discharge holes 44A, 44B, and can receive the auxiliary flushing water flow Fb discharged from the auxiliary water discharge holes 44A, 44B. The guide portion 46 can guide the auxiliary flushing water flow Fb traveling on the guide portion 46 toward the radially outer side of the toilet bowl portion 16. This allows the auxiliary flushing water flow Fb to have a radially outward velocity component when it leaves the guide portion 46.

See Figures 5, 6, and 8. The area on the inner surface of the toilet bowl 16 that is cleaned by the main flush water flow Fa is called the main flush area Ra, and the area on that inner surface that is above the main flush water flow Fa is called the upper area Rb. The main flush area Ra is the area on the inner surface of the toilet bowl 16 through which the main flush water flow Fa reaches in one toilet flush. The upper area Rb is the area on the inner surface of the toilet bowl 16 through which the main flush water flow Fa does not reach in one toilet flush. The upper area Rb can be considered as a non-cleaned area on the inner surface of the toilet bowl 16 that is not cleaned by the main flush water flow Fa.

The auxiliary water dischargers 40A and 40B supply the auxiliary flush water flow Fb to the upper region Rb on the inner circumferential surface of the toilet bowl 16. In this embodiment, this upper region Rb is provided on the upright surface 24 of the toilet bowl 16. In FIG. 8, the range on the inner circumferential surface of the toilet bowl 16 through which the auxiliary flush water flow Fb flows is hatched. The auxiliary water dischargers 40A and 40B supply the auxiliary flush water flow Fb to a portion of the inner circumferential surface of the toilet bowl 16 that overlaps with the casing 14 in the vertical direction. The water flow leaving the auxiliary water dischargers 40A and 40B is supplied to the upper region Rb by hitting the inner circumferential surface of the toilet bowl 16 directly without passing through other portions of the toilet body 12 (for example, the upper surface portion 28).

The secondary flushing water flow Fb that hits the upper region Rb flows down the inner surface of the toilet bowl 16 from the point of impact toward the bottom of the toilet bowl 16. This allows dirt on the upper region Rb to be washed away by the secondary flushing water flow.

See Figures 1 and 8. The range extending from the main water discharge hole 32 toward the swirling direction Da of the main flushing water flow Fa over half the circumference of the toilet bowl 16 is called the first half range Rc1, and the range extending over the remaining half of the circumference of the toilet bowl 16 is called the second half range Rc2. In this embodiment, the secondary water discharge sections 40A and 40B supply the secondary flushing water flow Fb to the upper region Rb in the second half range Rc2. In this embodiment, the secondary flushing water flow Fb is supplied to the upper region Rb behind the center CL of the toilet bowl 16.

The conditions described so far are met by both of the auxiliary water discharge sections 40A and 40B. In this embodiment, the auxiliary water discharge holes 44A and 44B are slits, so the auxiliary water discharge sections 40A and 40B supply a band-shaped auxiliary cleaning water flow Fb that extends in the circumferential direction.

The effects of the toilet device 10 described above will now be explained.

The toilet device 10 of this embodiment is equipped with secondary water discharge sections 40A, 40B that supply secondary flushing water flow Fb to an upper region Rb that is different from the main flushing region Ra. Therefore, the secondary flushing water flow Fb can widen the flushing range within the toilet bowl 16. In order to widen the flushing range in this way, it is not necessary to increase the flow rate of the main flushing water flow Fa. Therefore, it is possible to widen the flushing range while preventing splashing that occurs when the flow rate of the main flushing water flow Fa is increased.

The auxiliary water dischargers 40A, 40B are provided with guide portions 46 that guide the auxiliary flushing water flow Fb radially outward. Therefore, when the auxiliary water dischargers 40A, 40B are positioned radially inward relative to the upper region Rb, it becomes easier for the auxiliary flushing water flow Fb to reach hard-to-reach locations in the upper region Rb. As a result, the cleaning range of the toilet bowl 16 can be further expanded. Here, the "hard-to-reach locations" are, for example, locations near the upper end opening 16a of the toilet bowl 16 (see also Figures 5 and 6).

The auxiliary water discharge sections 40A and 40B are positioned radially inward from the upper end opening 16a of the toilet bowl 16. This allows the auxiliary flushing water flow Fb leaving the auxiliary water discharge sections 40A and 40B to hit the inner surface of the toilet bowl 16 directly, making it easier to wash away dirt with the powerful auxiliary flushing water flow Fb.

The secondary water discharge holes 44A, 44B are slits that extend in the circumferential direction of the toilet bowl 16. Therefore, a band-shaped secondary flushing water flow Fb can be supplied from the secondary water discharge parts 40A, 40B, and the cleaning range by the secondary flushing water flow Fb can be made wider in the circumferential direction.

The multiple secondary water discharge sections 40A, 40B are provided at locations spaced apart in the circumferential direction of the toilet bowl 16. This allows the cleaning range provided by the secondary cleaning water flow Fb to be wide in the circumferential direction.

In the rear range Rc2 of the toilet bowl 16, gravity makes it difficult for the main flush water flow Fa to reach high positions, and the boundary position Bp (see Figures 5 and 6) between the main flush area Ra and the upper area Rb tends to be low. In other words, the vertical range of the upper area Rb tends to be wide, making it easier for dirt to remain. By supplying the secondary flush water flow Fb to such areas where dirt is likely to remain, the remaining dirt can be washed away effectively.

The areas on the inner circumferential surface of the toilet bowl 16 that overlap with the casing 14 in the vertical direction Z are difficult to reach, making it difficult to wipe off dirt. The secondary water discharge sections 40A and 40B supply the secondary flushing water flow Fb to such areas. This makes it easier to wash away dirt in hard-to-reach areas with the secondary flushing water flow Fb.

Refer to Figure 9. The toilet device 10 includes a first main water passage 62 that supplies water supplied from a first water supply source 60 to the main water discharge section 30 as flush water, and a second main water passage 68 that supplies water supplied from a second water supply source 64 to a water-utilizing component 66.

The first water supply source 60 and the second water supply source 64 are, for example, a water supply system, a tank, etc. The second water supply source 64 may share the first water supply source 60, or may be separate from the first water supply source 60. Each water supply source 60, 64 may be supplied with temperature-adjusted water through a hot and cold water mixing valve.

The water-using part 66 is a part that uses water to function. In this embodiment, the water-using part 66 is disposed inside the casing 14. The water-using part 66 is, for example, a nozzle disposed inside the casing 14 as part of the local cleansing device. The water-using part 66 may also be an ejector of a foam supply device, a tank, etc.

The toilet device 10 is provided with a sub-water passage 70 that supplies water from the second water supply source 64 to the sub-water outlets 40A and 40B as flushing water. The sub-water passage 70 branches off from the second main water passage 68.

The toilet device 10 includes a first main valve 72 that can open and close the first main water passage 62, a second main valve 74 that can open and close the second main water passage 68, a sub-valve 76 that can open and close the sub-water passage 70, and a temperature sensor 78 that detects the temperature of the water flowing through the second main water passage 68. Each of the valves 72, 74, and 76 is an electrically driven valve such as a solenoid valve or an electric valve.

The toilet device 10 is equipped with a control device 80 that can control the open/closed state of each of the valves 72, 74, and 76. The control device 80 is a computer that combines hardware such as a CPU, ROM, and RAM with software.

When a predetermined flushing condition is met, the control device 80 executes a flushing operation to flush the inside of the toilet bowl 16 with the main flushing water flow Fa. The flushing condition is, for example, that the control device 80 acquires a flushing command output from a remote controller or the like. The flushing operation is executed by keeping the first main valve 72 open for a predetermined time. As a result, flush water is supplied from the first main water passage 62 to the main water discharge section 30, and the inside of the toilet bowl 16 is flushed with the main flushing water flow Fa.

When a predetermined start condition is satisfied, the control device 80 executes a water supply operation to operate the water utilization component 66. The start condition is, for example, that the control device 80 acquires a start command output from a remote controller or the like. In this water supply operation, when attempting to supply wash water in an appropriate temperature range from the second water supply source 64, cold stagnant water may remain in the second main water passage 68. To prevent this cold stagnant water from being supplied to the water utilization component 66, i.e., to prevent the cold stagnant water from being sprayed from the nozzle, the control device 80 executes water discard control in the water supply operation.

This waste water control is performed by switching the open/closed state of the second main valve 74 and the sub-valve 76 based on the detection result of the temperature sensor 78. In detail, when the temperature detected by the temperature sensor 78 is outside a predetermined suitable temperature range, the control device 80 opens the sub-valve 76 while keeping the second main valve 74 closed. As a result, water outside the suitable temperature range (e.g., cold stagnant water) is supplied as waste water to the sub-discharge sections 40A and 40B through the sub-water passage 70. On the other hand, when the detected temperature is within the suitable temperature range, the control device 80 opens the second main valve 74 while keeping the sub-valve 76 closed. As a result, water within the suitable temperature range is supplied to the water utilization component 66 through the second main water passage 68, and the water is used by the water utilization component 66.

When waste water is supplied to the auxiliary water discharge sections 40A, 40B by the above waste water control, the auxiliary water discharge sections 40A, 40B use the waste water to supply the auxiliary washing water flow Fb. The auxiliary water discharge sections 40A, 40B supply the auxiliary washing water flow Fb using water supplied at a timing different from the washing operation. Here, "waste water" refers to water that is generated within the casing 14 and should be discarded to the outside. In this embodiment, the waste water is water that is discarded without being used by the water utilization component 66.

Other variations of each component are described below.

Unlike the embodiment, the casing 14 may be configured as a toilet seat (not shown).

The number of main water discharge sections 30 is not particularly limited. For example, there may be two or more main water discharge sections 30. The main water discharge sections 30 may be provided separately from the toilet body 12.

An example has been described in which the auxiliary water discharge sections 40A, 40B are provided in the casing 14 as part of the casing 14. Alternatively, the auxiliary water discharge sections 40A, 40B may be provided in a nozzle separate from the casing 14. An example has been described in which the auxiliary water discharge sections 40A, 40B supply the auxiliary flushing water flow Fb to the upper region Rb of the toilet bowl 16 by directing the auxiliary flushing water flow Fb at the upper region Rb. This is not limiting, and the auxiliary water discharge sections 40A, 40B may supply the auxiliary flushing water flow Fb to the upper region Rb of the toilet bowl 16 by running water that hits the recess 28a of the toilet body 12.

In the above example, the guide portion 46 of the auxiliary water discharge portion 40A, 40B is provided separately from the auxiliary water discharge holes 44A, 44B. Alternatively, the guide portion 46 may be provided as part of the auxiliary water discharge holes 44A, 44B. The guide portion 46 only needs to be able to guide the auxiliary cleaning water flow Fb radially outward, and may guide the auxiliary cleaning water flow Fb upward, or may not need to guide it in the vertical direction. This means that the guide portion 46 may extend upward as it moves radially outward, or may not need to extend in the vertical direction.

The secondary water discharge sections 40A, 40B may be positioned radially outward from the upper end opening 16a of the toilet bowl 16. This assumes, for example, that the secondary flushing water flow Fb is supplied to the upper region Rb of the toilet bowl 16 by flowing water that hits the recess 28a of the toilet body 12.

The shape of the secondary water discharge holes 44A, 44B is not particularly limited. For example, the secondary water discharge holes 44A, 44B may be round holes, unlike the embodiment.

The number of auxiliary water discharge sections 40A, 40B is not particularly limited. There may be one auxiliary water discharge section 40A, 40B, or three or more auxiliary water discharge sections 40A, 40B.

The secondary water discharge sections 40A and 40B may supply a secondary flushing water flow Fb to the upper region Rb in the front half range Rc1 of the toilet bowl 16.

The secondary water discharge sections 40A and 40B may supply the secondary flushing water flow Fb to a location on the inner circumferential surface of the toilet bowl 16 that does not overlap with the casing 14 in the vertical direction.

Specific examples of waste water supplied to the auxiliary water discharge sections 40A and 40B are not particularly limited. The waste water may be, for example, waste water used to clean the nozzles, or waste water overflowing from an open tank used in the air gap device. In addition, water dedicated to the auxiliary cleaning water flow Fb may be supplied to the auxiliary water discharge sections 40A and 40B instead of waste water.

The temperature of the water supplied to the auxiliary water discharge sections 40A, 40b is not particularly limited, and either cold water or hot water may be used. The components of the water supplied to the auxiliary water discharge sections 40A, 40B are not particularly limited. The water supplied to the auxiliary water discharge sections 40A, 40B may contain, for example, a disinfecting component, an antibacterial component, a deodorizing component, a detergent component, etc. It can also be said that the water supplied to the auxiliary water discharge sections 40A, 40B may be disinfected water, etc.

An example has been described in which the auxiliary water dischargers 40A and 40B supply the auxiliary flush water flow Fb using water supplied at a timing different from the flushing operation. The auxiliary water dischargers 40A and 40B may supply the auxiliary flush water flow Fb to the toilet bowl 16 in accordance with the timing of either the flushing operation or the preliminary operation. As described above, the flushing operation refers to the operation of supplying flush water to the main water discharger 30 to flush the inside of the toilet bowl 16 after using the toilet body 12. The preliminary operation refers to the operation of wetting the inside of the toilet bowl 16 by supplying water into the toilet bowl 16 in advance before using the toilet body 12. The preliminary operation is performed to make it difficult for waste to adhere to the toilet bowl 16 by wetting the inside of the toilet bowl 16 in advance.

When the auxiliary flush water flow Fb is supplied to the toilet bowl 16 in accordance with the timing of the flushing operation, the timing of supplying the main flush water flow Fa and the auxiliary flush water flow Fb to the toilet bowl 16 does not matter. For example, the main water discharge section 30 may supply the main flush water flow Fa to the toilet bowl 16 first, and then the auxiliary water discharge sections 40A and 40B may supply the auxiliary flush water flow Fb. Alternatively, the auxiliary water discharge sections 40A and 40B may supply the auxiliary flush water flow Fb first, and then the main water discharge section 30 may supply the main flush water flow Fa. Alternatively, the main water discharge section 30 and the auxiliary water discharge sections 40A and 40B may supply the main flush water flow Fa and the auxiliary flush water flow Fb simultaneously.

It is preferable that the flow velocity (m/s) of the secondary flushing water flow Fb supplied from the secondary water dischargers 40A and 40B is slower than the flow velocity of the main flushing water flow Fa supplied from the main water discharger 30. This can reduce splashing of flushing water outside the toilet bowl 16 compared to when this condition is not met. In particular, when the secondary flushing water flow Fb is supplied to the toilet bowl 16 in accordance with the timing of the flushing operation, this is effective in reducing splashing of splashes caused by the merging of the main flushing water flow Fa and the secondary flushing water flow Fb inside the toilet bowl 16. The "flow velocity of the main flushing water flow Fa" refers to the flow velocity at the time when it is discharged from the main water discharger 30. The "flow velocity of the secondary flushing water flow Fb" refers to the flow velocity at the time when it is discharged from the secondary water dischargers 40A and 40B.
