This disclosure relates to a toilet device.

Conventionally, technology has been proposed for flushing the toilet with the toilet lid closed to prevent flush water from splashing outside the toilet bowl during toilet flushing (see, for example, Patent Document 1). According to the technology in Patent Document 1, by controlling the toilet lid to close when the seat detection means detects that the user has left the seat, the toilet can be flushed with the toilet lid closed, which is said to prevent flush water from splashing outside the toilet bowl and spreading bacteria and viruses.

JP 2018-62774 A

In the technology of Patent Document 1, the toilet is flushed with the toilet lid closed, so splashes of flushing water can adhere to the underside of the toilet lid or the toilet seat, and can then adhere to the body of the user when using the toilet device.

Therefore, there is a need for a toilet device that can prevent splashes of flush water from splashing outside the toilet bowl when flushing the toilet, and also prevents splashes of flush water from adhering to the toilet lid and toilet seat when flushing the toilet.

The present disclosure relates to a toilet device that includes a toilet body having a toilet bowl, a toilet flushing unit that supplies flushing water into the toilet bowl to flush the toilet, a fluid supply unit that supplies fluid into the toilet bowl from the upper rear of the toilet body, and a control unit that controls the fluid supply unit, and when the toilet flushing unit flushes the toilet, the control unit controls the fluid supply unit to supply fluid into the toilet bowl from the upper rear of the toilet body to block at least a portion of the opening on the top surface of the toilet bowl and thereby executes splash suppression control to suppress splashing of flushing water in the toilet bowl.

FIG. FIG. 3 is a plan view of the toilet apparatus shown in FIG. 2 with the nozzle unit of the private parts washing unit removed. 2 is a block diagram showing the configuration of a control unit of a toilet apparatus according to an embodiment of the present disclosure. FIG. 13 is a flowchart showing an example of a process for splash prevention control of a toilet device according to an embodiment of the present disclosure.

One embodiment of the present disclosure will be described in detail below with reference to the drawings. In the following description, for convenience, the front-rear and left-right directions refer to the front-rear and left-right directions as seen by a user sitting on the toilet seat.

As shown in Figures 1 to 3, the toilet device 1 is a flush toilet device. The toilet device 1 includes a toilet body 2, a toilet cleaning unit 3, a toilet seat 5, a toilet lid 6, a control unit 50, a private parts cleaning unit 60, an opening/closing drive unit 70, a seating detection unit 80, and a fluid supply unit 100.

The toilet body 2 is composed of a bowl-shaped toilet bowl 4 that receives waste and stores water R at the bottom, a rim portion 40 that is provided along the periphery of the toilet bowl 4, and a drain pipe (not shown) that extends downward from the bottom of the toilet bowl 4. The rim portion 40 is formed with a rim water passage (not shown) that swirls flushing water along the periphery of the toilet bowl 4.

The toilet flushing section 3 comprises a tank cover 34 with a hand washing section 38 provided above, a flushing tank 35 that stores flushing water, a flushing mechanism 36 that supplies the flushing water stored in the flushing tank 35 into the toilet bowl 4, and a handle 37. The flushing mechanism 36 has, for example, a ball tap water supply mechanism (not shown) that supplies water into the flushing tank 35, and a drain valve mechanism (not shown) that opens and closes a drain port formed in the bottom of the flushing tank 35 by rotation of a rotating shaft to which the rotational motion of the handle 37 is transmitted. When the user manually rotates the handle 37, the ball tap water supply mechanism and the drain valve mechanism supply a predetermined amount of flushing water stored in the flushing tank 35 into the toilet bowl 4, and also supply a predetermined amount of water into the flushing tank 35.

The cleaning mechanism 36 according to this embodiment is not limited to the manual cleaning mechanism described above, but may be an electric cleaning mechanism. The electric cleaning mechanism may, for example, include an electric actuator that is controlled by the control unit 50 (described later) to rotate the rotating shaft, and a remote controller that transmits a signal to the control unit 50 to drive the electric actuator.

The toilet seat 5 is provided so as to be openable and closable relative to the toilet body 2. Similarly, the toilet lid 6 is provided so as to be openable and closable relative to the toilet body 2, and when closed, covers the opening on the top surface of the toilet bowl 4. The toilet seat 5 and toilet lid 6 are opened and closed by an opening/closing drive unit 70 having a rotating drive shaft controlled by a control unit 50, which will be described later.

The local cleaning unit 60 is provided at the upper rear of the toilet body 2. The local cleaning unit 60 is housed in a case 7 that houses various functional parts. The case 7 has a base 8 that is installed on the upper rear surface of the toilet body 2, a shutter 10 that opens and closes a horizontally long opening 9 formed in the center of the front surface of the base 8, and a cover 11 that is attached to the base 8 and covers the various functional parts.

The private parts washing unit 60 includes a nozzle unit 12 that ejects washing water onto the private parts of a user seated on the toilet seat 5, and a hot water supply unit 13 that supplies hot water to the nozzle unit 12. The private parts washing unit 60 is driven and controlled by the control unit 50, which will be described later.

The nozzle unit 12 is disposed in the center of the base 8. The nozzle unit 12 has a cleaning nozzle 18 for cleaning the anus, a nozzle drive mechanism 19 for driving the cleaning nozzle 18, a bidet cleaning nozzle 20 disposed alongside the cleaning nozzle 18, and a nozzle drive mechanism 21 for driving the cleaning nozzle 20. The cleaning nozzles 18 and 20 each have a discharge hole 22 on the upper surface of the tip through which cleaning water supplied by the warm water supply unit 13, which will be described later, is discharged towards the user's private parts.

The cleaning nozzles 18, 20 have a cylindrical nozzle body and are positioned so that their tips are inclined downward. The cleaning nozzles 18, 20 are moved forward and backward relative to the toilet bowl 4 independently of each other by the nozzle drive mechanisms 19, 21, thereby opening and closing the shutter 10. Specifically, when the cleaning nozzles 18, 20 move forward relative to the toilet bowl 4, the tip of the nozzle body abuts against the inside of the shutter 10 and presses against the toilet bowl 4, opening the shutter 10, and when the cleaning nozzles 18, 20 move backward relative to the toilet bowl 4, the pressure is released and the shutter 10 closes.

The hot water supply unit 13 is disposed at one end of the base 8 in the left-right direction, for example, on the right side as shown in Figures 2 and 3. The hot water supply unit 13 is connected to each cleaning nozzle 18, 20 via individual supply pipes, and supplies hot water adjusted to a set temperature as cleaning water to each cleaning nozzle 18, 20.

The seating detection unit 80 detects when a user sits on the toilet seat 5. The seating detection unit 80 is provided, for example, on the front of the upper part of the cover 11 and is composed of an infrared sensor. The seating detection unit 80 detects when a user sits on the toilet seat 5 by emitting infrared light from a light-emitting element and receiving the infrared light reflected by the seated user's body with a light-receiving element. The detection signal of the seating detection unit 80 is transmitted to the control unit 50, which will be described later. The seating detection unit 80 of this embodiment is not limited to being composed of an infrared sensor, and may be composed of, for example, a contact detection sensor such as an electrostatic sensor.

The toilet device 1 of the present disclosure may include a human body detection unit (not shown). The human body detection unit detects a user approaching the toilet device 1. The human body detection unit is, for example, configured with an infrared sensor similar to the seating detection unit 80 described above, and the detection signal is transmitted to the control unit 50 described below. The detection unit in the present disclosure is configured with at least one of the seating detection unit 80 and the human body detection unit.

The fluid supply unit 100 supplies fluid into the toilet bowl 4 from the upper rear of the toilet body 2. The fluid supply unit 100 of this embodiment includes an air blower 110 that blows air into the toilet bowl 4, an ion generator 27 that generates ions and supplies the ions to the air blower 110, a water discharger 120 that discharges water into the toilet bowl 4, and a sterilized water generator 42 that generates sterilized water and supplies it to the water discharger 120. The fluid supply unit 100 is driven and controlled by a control unit 50, which will be described later. The fluid supply unit 100 of this embodiment may be configured not to include the ion generator 27 or the sterilized water generator 42 described above.

The air blowing section 110 blows air into the toilet bowl 4. As shown in Figures 2 and 3, the air blowing section 110 includes an air blowing unit 14 that blows air, and a deodorizing unit 15 that removes odors from inside the toilet bowl 4 that arise from waste.

The blower unit 14 is disposed at one end of the base 8 in the left-right direction, for example, on the right side as shown in Figs. 2 and 3. The blower unit 14 includes a blower duct 24 that guides outside air to the opening 9, a first blower 25 provided in the blower duct 24, and a heater 26 provided downstream of the first blower 25 in the blower duct 24.

The air duct 24 has an outside air intake (not shown) at its upstream end, and an outlet 28 at its downstream end that faces the toilet bowl 4 from the inside of the opening 9. The air duct 24 takes in outside air from the intake and blows it out from the outlet 28 when driven by the first blower 25. The first blower 25 generates an airflow in the air duct 24 from the intake to the outlet 28. The heater 26 warms the air taken in by the air duct 24.

As shown in Figs. 2 and 3, the air outlet 28 in this embodiment is disposed inside the shutter 10. Therefore, when the shutter 10 is closed, a gap is formed between the shutter 10 and the edge of the opening 9, and this gap functions as the air outlet 45. Therefore, the air blown out from the air outlet 28 is sent out from the air outlet 45 into the toilet bowl 4. Instead of the shutter 10, the air outlet 28 may be provided with a separate air outlet shutter that opens the air outlet 28 with the blown out air and closes the air outlet 28 by its own weight.

The air sent into the toilet bowl 4 from the above-mentioned air outlet 45 generates a swirling current that swirls above the water level in the toilet bowl 4, as shown by the arrows in FIG. 2, in conjunction with the suction action of the deodorizing unit 15 described below. This swirling current functions as an air shield (registered trademark), blocking at least a portion of the opening on the top surface of the toilet bowl 4. This prevents odors generated from waste from leaking out of the toilet bowl 4 when a user is detected by the detection unit. If the toilet is being flushed, it prevents odors from leaking out of the toilet bowl 4 and also prevents splashes of flushing water. This will be explained in detail later as cleaning control and splash suppression control by the control unit 50.

The ion generating unit 27 is provided downstream of the first blower 25 in the air blower duct 24. As the ion generating unit 27, for example, a device capable of suppressing the action of airborne viruses in the air and decomposing and removing airborne mold bacteria by using ions generated by plasma discharge, or various devices that generate ions for sterilization and deodorization in the air, such as an electrostatic atomizer, can be used. Such an ion generating unit 27 ionizes the air taken into the air blower duct 24 to generate positive ions and negative ions. As a result, the air blower 110 blows out ionized air containing positive ions and negative ions from the air outlet 28, and supplies the ionized air into the toilet bowl 4 through the air outlet 45, thereby generating a swirling flow in the toilet bowl 4 and inactivating airborne bacteria in the toilet bowl 4.

The deodorizing unit 15 is disposed at one end of the base 8 in the left-right direction, for example, on the left side as shown in Figures 2 and 3. The deodorizing unit 15 includes a deodorizing duct 29 that guides air from within the toilet bowl 4 to the outside of the toilet bowl 4, a second blower 30 provided within the deodorizing duct 29, and a deodorizing cartridge 31 provided downstream of the second blower 30 within the deodorizing duct 29.

The deodorizing duct 29 has an intake port 32 formed near the front center of the base 8 at its upstream end, and an outlet port 33 formed on one end side of the base 8 in the left-right direction, for example, on the left side as shown in Figures 2 and 3, at its downstream end. The deodorizing duct 29 draws in air and odors from the toilet bowl 4 through the intake port 32 and blows out air from the outlet port 33 by driving the second blower 30. In other words, the deodorizing unit 15 of this embodiment is a non-circulation type (one-pass type) deodorizing device. The second blower 30 generates an airflow from the intake port 32 to the outlet port 33 in the deodorizing duct 29. The deodorizing cartridge 31 contains a deodorizing catalyst, and removes odors contained in the air by passing the air drawn into the deodorizing duct 29.

The suction port 32 is formed on the bottom surface of the base 8, opens downward, and faces the inside of the toilet bowl 4. In other words, since there is no suction port inside the shutter 10, but rather the suction port is formed on the bottom surface of the base 8, air and odors inside the toilet bowl 4 can be sucked in even when the shutter 10 is closed.

The deodorizing cartridge 31 can be an adsorption type deodorizer that uses activated carbon or the like as a catalyst. A decomposition type that has the function of decomposing substances by irradiating them with light such as ultraviolet light, such as a photocatalyst, can also be used as the deodorizing cartridge 31.

As described above, in addition to the air being blown into the toilet bowl 4 by the blower unit 14, the deodorizer unit 15 sucks in the air and odors in the toilet bowl 4, which promotes the generation of a swirling flow in the toilet bowl 4. However, the deodorizer unit 15 does not necessarily need to have a blower or suction device such as the second blower 30 described above, and only needs to have a deodorizer duct 29. As described above, the deodorizer is not limited to a non-circulation (one-pass) type that sucks in the air and odors in the toilet bowl 4 from the suction port 32 and blows out air from the outlet 33, but a circulation type deodorizer that circulates air to the blower unit 14 can also be used.

The water discharge unit 120 discharges water into the toilet bowl 4. As shown in FIG. 3, the water discharge unit 120 includes a mist nozzle 41 that discharges water in the form of a mist into the toilet bowl 4, and a sterilizing water supply pipe 43 that supplies sterilizing water from a sterilizing water generating unit 42 to the mist nozzle 41.

The mist nozzle 41 is disposed in the center of the base 8. That is, as shown in FIG. 3, the mist nozzle 41 is disposed below the nozzle unit 12 of the local cleansing section 60. The tip of the mist nozzle 41 is disposed so as to be inclined downward, and the mist nozzle 41 discharges water into the toilet bowl 4 as shown by the arrow in FIG. 3. More specifically, the mist nozzle 41 discharges water in the form of a mist onto the inner wall surface of the toilet bowl 4. A disinfectant water supply pipe 43 is connected to the mist nozzle 41, and the disinfectant water generated in the disinfectant water generating section 42 is supplied to the mist nozzle 41 via the disinfectant water supply pipe 43 and discharged into the toilet bowl 4.

When the detection unit detects a user, water is discharged in a mist form from the mist nozzle 41, which causes the inner wall surface of the toilet bowl 4 to become wet in advance, thereby preventing waste from adhering to the inner wall surface of the toilet bowl 4. When the toilet is being flushed, this mist blocks at least a portion of the opening on the top surface of the toilet bowl 4, preventing the flush water from splashing inside the toilet bowl 4. This will be explained in detail later as cleaning control and splash prevention control by the control unit 50.

The disinfectant water generating unit 42 generates disinfectant water by electrolyzing water supplied from a water supply source (not shown). Here, the disinfectant water may be, for example, water containing hypochlorous acid or water containing metal ions. Water containing metal ions is, for example, water containing at least one of silver ions, copper ions, and zinc ions. Water containing ozone is also included in the disinfectant water. The disinfectant water generating unit 42 may generate disinfectant water by dissolving a disinfectant or disinfectant liquid in water. The disinfectant water generating unit 42 is controlled by the control unit 50 described later to generate disinfectant water and supply it to the water discharge unit 120 via the disinfectant water supply pipe 43.

As shown in Figs. 2 and 3, the control unit 50 has a control board and is disposed at one end of the base 8 in the left-right direction, for example, on the left side as shown in Figs. 2 and 3. The toilet device 1 is also provided with a power supply board 17 that supplies power to the control unit 50 and various functional components. The functions of the control unit 50 described below are realized as hardware by various elements such as a CPU, and as software by a computer program or the like. As shown in Fig. 4, the control unit 50 has, as its functional components, a splash prevention control unit 51, a purification control unit 52, and an opening/closing drive control unit 53. The splash prevention control unit 51 has an air supply control unit 511, an ion generation control unit 512, a water discharge control unit 513, and a disinfectant water generation control unit 514.

The splash suppression control unit 51 executes splash suppression control when the toilet flushing unit 3 flushes the toilet. Specifically, when the toilet flushing unit 3 flushes the toilet, the splash suppression control unit 51 controls the above-mentioned air blowing unit 110 via the air blowing control unit 511 to blow air into the toilet bowl 4, thereby blocking at least a portion of the opening on the top surface of the toilet bowl 4 and suppressing the scattering of splashes of the flushing water within the toilet bowl 4. At the same time, the splash suppression control unit 51 may control the ion generation unit 27 via the ion generation control unit 512 to supply ionic wind into the toilet bowl 4.

When the toilet flushing unit 3 flushes the toilet, the splash prevention control unit 51 controls the water discharge unit 120 described above using the water discharge control unit 513 to discharge water into the toilet bowl 4, thereby blocking at least a portion of the opening on the top surface of the toilet bowl 4 and suppressing splashing of flushing water inside the toilet bowl 4. At the same time, the splash prevention control unit 51 may control the sterilizing water generation unit 42 using the sterilizing water generation control unit 514 to discharge sterilizing water into the toilet bowl 4.

The splash suppression control unit 51 may execute splash suppression control by only one of the air blowing control unit 511 and the water discharge control unit 513, or may execute splash suppression control by performing both simultaneously. After starting to execute splash suppression control, the splash suppression control unit 51 continues to execute splash suppression control until toilet flushing ends. The end of toilet flushing may be when the amount of flush water supplied becomes small enough that splashes of flush water are no longer scattered, or when the supply amount becomes zero. After toilet flushing ends, splash suppression control may continue for a predetermined time.

When performing splash suppression control, the splash suppression control unit 51 may increase the amount of airflow and mist discharged per unit time supplied into the toilet bowl 4 compared to when performing cleaning control, which will be described later. In other words, when flushing the toilet when the user is not seated or the toilet seat is up, the splash suppression control unit 51 increases the amount of airflow and mist discharged compared to when the user is detected by the detection unit. This makes it possible to more reliably suppress the scattering of splashes of flush water during toilet flushing.

When performing splash suppression control, the splash suppression control unit 51 may change the direction of the airflow supplied into the toilet bowl 4 and the range of mist spray compared to when performing cleaning control, which will be described later. For example, by changing the direction of the airflow or widening the range of mist spray so as to generate a large swirling current that more reliably blocks the opening on the top surface of the toilet bowl 4, splashes of flushing water during toilet flushing can be more reliably suppressed.

When the detection unit detects a user, the cleaning control unit 52 controls at least one of the air blowing unit 110 and the water discharge unit 120 to blow air and discharge water from the upper rear of the toilet body 2 into the toilet bowl 4, thereby performing cleaning control to clean the inside of the toilet bowl 4. When the detection unit detects a user, this is at least one of the following: when the seating detection unit 80 detects that the user is sitting on the toilet seat 5, and when the human body detection unit detects that the user is approaching the toilet device 1. At the same time, the cleaning control unit 52 may control the ion generation unit 27 and the sterilizing water generation unit 42 to discharge ion air or sterilizing water into the toilet bowl 4 for cleaning. As a result, when the detection unit detects a user, the air blowing can prevent the odor generated from the waste from leaking out of the toilet bowl 4, and the water discharge can prevent the waste from adhering to the inner wall surface of the toilet bowl 4 by moistening the inner wall surface of the toilet bowl 4 in advance.

The opening/closing drive control unit 53 controls the opening/closing drive unit 70. The toilet seat 5 and toilet lid 6 open and close as a result of the opening/closing drive unit 70 being controlled by the opening/closing drive control unit 53. In particular, the opening/closing drive control unit 53 may control the opening/closing drive unit 70 to close the toilet lid 6 when the above-mentioned splash prevention control is being performed. In conventional technology, when the toilet is flushed with the toilet lid closed, splashes of the flushing water adhere to the back side of the toilet lid and the toilet seat, whereas in the splash prevention control of this embodiment, splashing of the flushing water is suppressed by blowing air and discharging water, so splashes can be prevented from adhering to the back side of the toilet lid 6 and the toilet seat.

An example of the droplet suppression control process performed by the control unit 50 of the toilet device 1 according to this embodiment will be described in detail with reference to FIG. 5.

The splash prevention control shown in FIG. 5 is triggered by, for example, the toilet flushing operation by the user, or by the start of automatic flushing after a predetermined time has elapsed since the user left the seat, etc.

First, in step S11, it is determined whether the toilet device 1 is flushing the toilet. If the result of this determination is YES, the process proceeds to step S12; if the result is NO, the determination of step S11 is repeated. Whether the toilet is flushing is known by the control unit 50, and may be determined, for example, based on the seating detection unit 80 detecting that the user has left their seat, or may be determined by detecting the position information of the rotating shaft of the flushing mechanism 36 in the toilet flushing unit 3 or the state of the drain valve of the drain valve mechanism using various sensors. In the case of an electric flushing mechanism, it may be determined based on the presence or absence of a flushing mechanism drive signal transmitted from a remote controller to the control unit 50.

Next, in step S12, splash suppression control is started because the toilet device 1 is in the process of flushing the toilet. After splash suppression control is started, the process proceeds to step S13. The splash suppression control may be started before or after the start of the toilet flush. Alternatively, splash suppression control may be started simultaneously with the start of the toilet flush. When splash suppression control is started before or simultaneously with the start of the toilet flush, splash suppression control may be started, for example, based on detection of the user leaving the seat by the seating detection unit 80. When a male is urinating, splash suppression control may be started based on a detection signal from a human body detection unit provided in the toilet device 1.

Next, in step S13, it is determined again whether the toilet is being flushed. The determination of whether the toilet is being flushed is performed in the same manner as in step S11. If the result of this determination is YES, the toilet is still being flushed, so splash prevention control continues, and the determination of this step is repeatedly performed. If the result of this determination is NO, the toilet flush has ended, so splash prevention control ends, and this process ends.

According to the toilet device 1 of this embodiment described above, when the toilet is flushed by the toilet flushing unit 3, the fluid supply unit 100, which is composed of the air blowing unit 110 and the water discharge unit 120, is controlled to blow air and discharge water from the upper rear of the toilet body 2 into the toilet bowl 4, thereby blocking at least a portion of the opening on the top surface of the toilet bowl 4 and preventing the scattering of flushing water droplets within the toilet bowl 4. This in turn prevents the flushing water droplets from scattering outside the toilet bowl 4, thereby preventing the spread of bacteria and viruses.

In addition, according to this embodiment, even if the toilet lid 6 is not closed when flushing the toilet, splashing of flush water outside the toilet bowl 4 can be prevented, and therefore splashing of flush water onto the underside of the toilet lid 6 or the toilet seat 5 can be prevented from adhering to the body of the user who next uses the toilet device 1. Therefore, according to the toilet device 1 of this embodiment, splashing of flush water outside the toilet bowl 4 during toilet flushing can be prevented, and splashing of flush water during toilet flushing can be prevented from adhering to the toilet lid 6 or the toilet seat 5.

In addition, according to this embodiment, splashing of flush water outside the toilet bowl 4 can be prevented even if the toilet lid 6 is not closed when flushing the toilet, so the user can visually check whether the waste has been completely flushed away by the toilet flush. Furthermore, because splash suppression control is performed during toilet flushing when the user is not seated, the user's buttocks are not exposed to uncomfortable wind or mist, and the effect of preventing splashing of flush water during toilet flushing can be achieved.
