[0022] As shown in Figure 1, the toilet apparatus 10 includes a toilet body 20, a toilet apparatus 30, and a remote controller 60. When the remote controller 60 is operated, the toilet apparatus 10 operates various functions of the toilet apparatus 30. The toilet apparatus 10 can perform a toilet lid closing operation, which rotates the toilet lid 32 into a reclined position, before executing a toilet flush.

[0023] [Toilet body configuration] The toilet body 20 is a floor-standing flush toilet that is placed on the floor of the toilet room R. The toilet body 20 is formed with a toilet bowl 21. The toilet bowl 21 is bowl-shaped with a roughly oval opening at the top end. A water reservoir (not shown) where flush water accumulates is formed at the bottom of the toilet bowl 21. The water reservoir is connected to a drainage channel (not shown) through which the flush water is discharged.

[0024] [Toilet equipment configuration] The toilet device 30 is attached to the top surface of the toilet body 20. The toilet device 30 has a toilet seat 31, a toilet lid 32, and a body 33. As shown in Figure 2, the body 33 has a control unit 51, a toilet seat opening / closing device 48, a toilet lid opening / closing device 49, a toilet flushing device 41, a seating detection unit 43, a first human body detection unit 44A, a second human body detection unit 44B, a toilet lid detection unit 45, a deodorizing device 46, a sterilizing device 47, a remote controller 60, and the like. The body 33 is detachably fixed to the toilet body 20. The body 33 supports the toilet seat 31 and the toilet lid 32 so that they can rotate freely between a reclined position and an upright position.

[0025] The toilet seat 31 is formed in a ring shape with an opening on the inside. The toilet seat 31 is supported by the main body 33 so as to be able to rotate freely between an upright position and a reclined position. In the reclined position, the toilet seat 31 is positioned along the upper end of the toilet bowl 21 of the toilet body 20. The toilet lid 32 is supported by the main body 33 so as to be able to rotate freely between an upright position and a reclined position. In the reclined position, the toilet lid 32 is in a closed state, covering the toilet seat 31 from above and blocking the openings of the toilet seat 31 and the toilet bowl 21, and in the upright position, is in an open state, opening the openings of the toilet seat 31 and the toilet bowl 21.

[0026] The control unit 51 is configured as, for example, a microcomputer, and functions to control the discharge of flush water into the toilet body 20, the opening and closing operations of the toilet lid 32 and toilet seat 31, the operation of the deodorizing device 46, the sterilizing device 47, etc. Based on signals transmitted from the remote controller 60, the control unit 51 can control the discharge of flush water from the toilet body 20, the opening and closing operations of the toilet lid 32 and toilet seat 31, the operation of the deodorizing device 46, the sterilizing device 47, etc.

[0027] The toilet seat opening / closing device 48 is configured by, for example, a motor, etc. The control unit 51 drives the motor of the toilet seat opening / closing device 48 to rotate based on a signal sent from the remote controller 60.

[0028] The toilet lid opening / closing device 49 is composed of, for example, a motor. The control unit 51 drives the motor of the toilet lid opening / closing device 49 to rotate based on a signal sent from the remote controller 60. In this way, the toilet lid opening / closing device 49 rotates the toilet lid 32 between an upright position and a reclined position.

[0029] The toilet flushing device 41 is a device that supplies flush water to the toilet body 20. The toilet flushing device 41 is provided with a water supply channel that supplies flush water, such as tap water, to the toilet body 20. The water supply channel is connected to the toilet bowl 21. A water supply valve is provided midway along the water supply channel. The water supply valve is configured as, for example, a solenoid valve. The water supply channel and water supply valve are not shown. Based on a signal received from the remote controller 60, the control unit 51 opens the water supply valve of the toilet flushing device 41, opens the water supply channel, and begins supplying flush water to the toilet body 20. In other words, the remote controller 60 commands toilet flushing and is a flush operation unit that the toilet flushing device 41 has. The control unit 51 closes the water supply valve after a predetermined time has elapsed, shuts off the water supply channel, and stops the supply of flush water to the toilet body 20. The toilet flushing device 41 performs toilet flushing by supplying flush water to the toilet body 20 to clean the toilet body 20.

[0030] The seating detection unit 43 detects when a user is seated on the toilet seat 31. The seating detection unit 43 is attached to the main body 33. The seating detection unit 43 is configured with a known infrared sensor. The seating detection unit 43 includes a light-emitting element (e.g., an LED) and a light-receiving element (e.g., a photodiode), both not shown. The seating detection unit 43 detects that a user is seated on the toilet seat 31 by emitting infrared light from the light-emitting element and receiving the infrared light reflected by the surface of the user seated on the toilet seat 31 with the light-receiving element. The seating detection unit 43 is configured to output a seating detection signal to the control unit 51 when it detects that a user is seated on the toilet seat 31.

[0031] The first human body detector 44A and the second human body detector 44B detect a human body located at a predetermined position (for example, within the toilet room R) relative to the toilet apparatus 30. The first human body detector 44A and the second human body detector 44B are configured with known infrared sensors and include a light-emitting element (for example, an LED, etc.) and a light-receiving element (for example, a photodiode, etc.), not shown. The first human body detector 44A and the second human body detector 44B detect the presence of a user in the toilet room R by receiving infrared light, which is generated from the light-emitting element and reflected by a human body located within the toilet room R, with the light-receiving element.

[0032] The first human body detector 44A detects a user in front of the front end of the toilet body 20 when the toilet lid 32 is in a reclined position. The first human body detector 44A is configured to output a first human body detection signal to the controller 51 when it detects a user.

[0033] The second human body detector 44B detects a user in front of the toilet body 20 when the toilet seat 31 is in an upright position. The second human body detector 44B is configured to be able to output a second human body detection signal to the controller 51 when it detects a user.

[0034] The toilet apparatus 30 is provided with a human body detection light-emitting unit 44C, which is a light-emitting unit that illuminates at least one of the periphery of the toilet body 20 and the interior of the toilet bowl 21 when the first human body detector 44A and the second human body detector 44B detect a human body located at a predetermined position relative to the toilet apparatus 30 (for example, in the toilet room R). The human body detection light-emitting unit 44C is configured, for example, from an LED. The color of the light emitted from the human body detection light-emitting unit 44C is, for example, white or warm white.

[0035] The toilet lid detector 45 detects the rotation state of the toilet lid 32. The toilet lid detector 45 is equipped with a known rotation detection means (e.g., a magnetic angle sensor that detects the orientation of a magnet that rotates with the toilet lid 32). The toilet lid detector 45 detects the difference in angle between the toilet lid 32 in the lying position and the toilet lid 32 in the upright position. The toilet lid detector 45 is configured to detect the difference in angle between the toilet lid 32 in the lying position and the toilet lid 32 in the upright position when the toilet lid 32 is rotated between the lying position and the upright position by the toilet lid opening / closing device 49, and when the toilet lid 32 is manually changed between the lying position and the upright position. The toilet lid detector 45 is configured to output a signal corresponding to the detected angle difference to the control unit 51.

[0036] The deodorizing device 46 has a duct with an air intake facing the inside of the toilet bowl 21, a fan installed in the duct, and a deodorizing filter. The duct, fan, and deodorizing filter are not shown. The deodorizing device 46 draws air from the inside of the toilet bowl 21 through the air intake by rotating the fan. The drawn-in air is deodorized by passing through the deodorizing filter. The deodorized air is discharged, for example, from an exhaust port formed in the rear of the main body 33. The exhaust port is not shown. In other words, the deodorizing device 46 deodorizes odors drawn in from the space below the down-turned toilet lid 32 (i.e., the space inside the toilet bowl 21).

[0037] The sterilization device 47 has a sterilization unit. The sterilization unit is not shown. The sterilization unit ionizes the air to generate positive ions and negative ions, which are sterilizing substances, and these positive and negative ions surround bacteria and viruses floating in the air. In this way, the sterilization device 47 inactivates the bacteria and viruses floating in the air. The sterilization device 47 is configured, for example, to release the positive and negative ions generated in the sterilization unit into the toilet bowl 21 through a release port facing the toilet bowl 21. The release port is not shown. In other words, the sterilization device 47 releases the positive and negative ions (sterilizing substances) toward the space below the downturned toilet lid 32 (i.e., the space inside the toilet bowl 21).

[0038] The sterilization device 47 is configured to perform cyclic operation, periodically repeating an operating state and a stopped state when no user is present in the toilet R. For example, the sterilization device 47 maintains the operating state for 45 minutes and the stopped state for 15 minutes. If a user enters the toilet R while the sterilization device 47 is in the operating state, the sterilization device 47 changes to the stopped state, and when the user leaves the toilet R and the toilet lid 32 is closed, the sterilization device 47 resumes operation from the operating state or the cyclic operation state. The sterilization device 47 can be operated cyclically or stopped (i.e., maintained in the stopped state) by the remote controller 60.

[0039] The toilet device 30 is provided with a sterilization device light-emitting unit that turns on, blinks, or turns off depending on the operating state of the sterilization device 47. The sterilization device light-emitting unit is configured, for example, with an LED or the like. The sterilization device light-emitting unit is not shown. The sterilization device light-emitting unit emits light of a color different from the color of light emitted from the human body detection light-emitting unit 44C (for example, bluish white, blue, etc.).

[0040] The toilet device 30 is provided with an alarm unit 50 configured with a buzzer or the like. The alarm unit 50 is controlled by a control unit 51 to emit an alarm sound.

[0041] The remote controller 60 has the function of operating various functions of the toilet apparatus 30. The remote controller 60 transmits a signal according to the user's operation to the control unit 51 of the toilet apparatus 30 as, for example, a wireless signal. The remote controller 60 is formed in a roughly rectangular parallelepiped shape. The remote controller 60 is attached to the wall of the toilet room R.

[0042] The remote controller 60 comprises a housing 60A and multiple operation buttons 63A. The housing 60A houses a microcomputer, a battery, etc. The multiple operation buttons 63A are operated to activate a desired function of the toilet device 30. Each operation button 63A is assigned one of various functions in advance. For example, each operation button 63A is assigned a function to open or close the toilet lid 32, open or close the toilet seat 31, start a toilet flush, etc.

[0043] In other words, the remote controller 60 is a toilet lid operating unit that commands the execution of either a toilet lid opening operation that rotates the toilet lid 32 from a lying down state to an upright state, or a toilet lid closing operation that rotates the toilet lid 32 from an upright state to a lying down state, and is a toilet lid operating unit that the toilet lid opening / closing device 49 has. Furthermore, the remote controller 60 is a toilet seat operating unit that the toilet seat opening / closing device 48 has, and is a toilet seat operating unit that commands the execution of either a toilet seat opening operation that rotates the toilet seat 31 from a lying down state to an upright state, or a toilet seat closing operation that rotates the toilet seat 31 from an upright state to a lying down state.

[0044] [About the operation of the toilet device] Next, the operation of the toilet apparatus 30 will be explained with reference to Figures 3, 4, etc. In the toilet apparatus 30, the toilet lid opening / closing device 49 performs a toilet lid closing operation in which the toilet lid 32 is rotated from an upright position to a laid-down position before the toilet flushing device 41 performs a toilet flush. In other words, the toilet apparatus 30 can supply flush water to the toilet body 20 to flush the toilet body 20 after the toilet lid 32 has performed the toilet lid closing operation (hereinafter also referred to as post-closing flushing). The toilet apparatus 30 is configured so that, by the user operating the remote controller 60, it can switch between a post-closing flush and a flush to the toilet body 20 by supplying flush water to the toilet body 20 before the toilet lid 32 performs the toilet lid closing operation (hereinafter also referred to as pre-closing flushing).

[0045] [When using the remote controller to close the door after sitting down and then cleaning it] In this case, first, a user enters the toilet room R. Then, the first human body detector 44A detects the user and outputs a first human body detection signal to the controller 51. The controller 51 then causes the toilet lid opening / closing device 49 to execute a toilet lid opening operation, rotating the toilet lid 32 from a lying down position to an upright position. At the same time, the controller 51 turns on the human body detection light emitting unit 44C and activates the deodorizing device 46.

[0046] Next, as shown in Fig. 3, at time T1, the user sits on the toilet seat 31. Then, the seat detection unit 43 detects that the user has sat on the toilet seat 31 and outputs a seat detection signal to the control unit 51. At this time, the control unit 51 starts playing predetermined music in a music playback unit provided in the main body 33 based on the input of the seat detection signal. The music playback unit is not shown.

[0047] Next, at time T2, the user leaves the toilet seat 31. The seating detection unit 43 then detects that the user has left the toilet seat 31 and stops outputting the seating detection signal. Then, at time T3, the user operates the operation button 63A on the remote controller 60, which corresponds to a toilet flush command. When the control unit 51 receives a wireless signal corresponding to the toilet flush command from the remote controller 60, it initiates a toilet lid closing operation, rotating the toilet lid 32 from an upright position to a laid-down position. At this time, the control unit 51 activates the alarm unit 50 to emit an alarm sound indicating that the toilet lid 32 has begun its toilet lid closing operation. At this time, the toilet lid detection unit 45 is in a state where it has detected a change in the angle of the toilet lid 32 as the toilet lid 32 rotates (i.e., it has detected the toilet lid closing operation). Signals corresponding to the angle of the toilet lid 32 detected by the toilet lid detection unit 45 are input to the control unit 51 one by one.

[0048] When the toilet apparatus 30 performs a pre-closing flush, the toilet flush is executed when the user leaves the toilet seat 31 and then operates the operation button 63A on the remote controller 60, which corresponds to a toilet flush command. A predetermined time (e.g., 60 seconds) has passed since the user left the toilet seat 31, and the control unit 51 begins the toilet lid closing operation. At this time, the control unit 51 operates the alarm unit 50 to emit an alarm sound indicating that the toilet lid 32 has started closing. In other words, in a pre-closing flush, the alarm unit 50 emits an alarm sound after the toilet flush is executed, and in a post-closing flush, the alarm unit 50 emits an alarm sound before the toilet flush is executed. In other words, the timing at which the alarm unit 50 emits an alarm sound differs between the pre-closing flush and the post-closing flush.

[0049] At time T4, when a predetermined time (for example, 6 seconds) has elapsed since time T2, control unit 51 stops the music playback unit from playing music.

[0050] Next, at time T5, the toilet lid 32 enters a lying position. At this time, the control unit 51 receives a signal from the toilet lid detection unit 45 that corresponds to the angle of the lying toilet lid 32. The control unit 51 then operates the toilet flushing device 41 based on the signal from the toilet lid detection unit 45 that corresponds to the lying position, and causes the supply of flush water to the toilet body 20 to begin. In other words, the toilet flushing device 41 performs a toilet flush after the toilet lid detection unit 45 detects the toilet lid closing operation. At this time, the control unit 51 turns on the sterilization device light-emitting unit and changes the sterilization device 47 to an operating state. At this time, the sterilization device 47 begins operation from the operating state of its cyclical operation.

[0051] Then, at time T6, the control unit 51 stops the operation of the toilet flushing device 41 and stops the supply of flush water to the toilet body 20. The human body detection light-emitting unit 44C continues to be illuminated by the control unit 51 even after time T6 has passed. In other words, the human body detection light-emitting unit 44C is illuminated at least while the toilet flushing device 41 is flushing after the toilet lid 32 has been placed in a reclined position. The control unit 51 does not perform the toilet lid opening operation for a predetermined time (e.g., 30 seconds) from time T5, even if a first human body detection signal is input from the first human body detector 44A (i.e., even if a user is detected in front of the front end of the toilet body 20 when the toilet lid 32 is in a reclined position). The predetermined time (30 seconds) from time T5 is an invalid period during which the control unit 51 does not accept the first human body detection signal. This predetermined time (30 seconds) is preferably longer than the time during which the toilet flushing device 41 performs toilet flushing. In other words, when the toilet lid 32 is in the down position and a predetermined time has elapsed since the toilet flushing device 41 started flushing, the toilet lid opening / closing device 49 will not perform the toilet lid opening operation even if the first human body detector 44A detects a user. During this invalid period, the toilet lid 32 can be manually rotated to the upright position.

[0052] The deodorizing device 46 also operates while the toilet flushing device 41 is flushing the toilet. In other words, the deodorizing device 46 operates while the toilet lid 32 is in the down position and the toilet flushing device 41 is flushing the toilet. The deodorizing device 46 continues to operate even after the toilet flushing device 41 has flushed the toilet and finished supplying flush water to the toilet body 20.

[0053] When the toilet lid 32 is in a reclined position and the toilet flushing device 41 is performing a toilet flush and supplying flush water to the toilet body 20, if the user operates the operation button 63A on the remote controller 60, which corresponds to an instruction to open the toilet lid 32, the toilet lid opening / closing device 49 will perform the toilet lid-opening operation. Furthermore, when the toilet lid 32 is in a reclined position and the toilet flushing device 41 is performing a toilet flush and supplying flush water to the toilet body 20, the user operates the operation button 63A on the remote controller 60, which corresponds to an instruction to open the toilet seat 31. Then, the toilet lid opening / closing device 49 will perform the toilet lid-opening operation, and the toilet seat opening / closing device 48 will perform the toilet seat-opening operation.

[0054] While the toilet lid 32 is performing the toilet lid closing operation, for example, if the user stops the rotation of the toilet lid 32, if the user manually rotates the toilet lid 32 to an upright position, or if the toilet lid opening / closing device 49 malfunctions, the angle of the toilet lid 32 detected by the toilet lid detection unit 45 will change differently from the angle that occurs when the toilet lid 32 normally closes. If the change in the angle of the toilet lid 32 is different from normal, the toilet lid detection unit 45 detects this as an abnormality in the toilet lid closing operation. When the toilet lid detection unit 45 detects an abnormality in the toilet lid closing operation in this way, the control unit 51 causes the toilet flushing device 41 to perform a toilet flush. In other words, when the toilet lid detection unit 45 detects an abnormality in the toilet lid closing operation, the toilet flushing device 41 performs a toilet flush.

[0055] For example, if a user obstructs the rotation of the toilet lid 32 while the toilet lid 32 is performing the toilet lid closing operation, causing the toilet lid 32 to rotate more slowly than usual, the time it takes for the toilet lid 32 to reach the down position will be longer than when the toilet lid 32 normally reaches the down position. If the time it takes to reach the down position is longer than usual, the toilet lid detection unit 45 detects this as an abnormality in the toilet lid closing operation. In this way, once the toilet lid detection unit 45 detects an abnormality in the toilet lid closing operation and a predetermined time (e.g., 10 seconds) has elapsed, the control unit 51 causes the toilet flushing device 41 to perform a toilet flush without waiting for the toilet lid 32 to reach the down position. In other words, once the predetermined time has elapsed after the toilet lid detection unit 45 detected an abnormality in the toilet lid closing operation, the toilet flushing device 41 will perform a toilet flush without waiting for the toilet lid 32 to reach the down position.

[0056] Next, at time T7, a predetermined time (e.g., 60 seconds) after time T2, the control unit 51 stops the operation of the deodorizing device 46. In other words, the deodorizing device 46 operates until a predetermined time has passed after the toilet flushing device 41 finishes flushing. At this time, the human body detection light-emitting unit 44C is turned off by the control unit 51. When the toilet lid 32 is in the down position, it is highly likely that a user has entered the toilet room R. Therefore, by keeping the human body detection light-emitting unit 44C lit until time T7 and turning it off at time T7, it is possible to extend the time that at least one of the area around the toilet body 20 and the inside of the toilet bowl 21 is illuminated, and when the toilet device 10 is used without turning on the lights provided in the toilet room R, it is possible to illuminate the area around the user's feet for a longer period of time.

[0057] Next, at time T8, when a predetermined time (for example, 60 seconds) has elapsed since time T5, the control unit 51 changes the sterilization device light-emitting unit from a lit state to a flashing state. In other words, the sterilization device 47 operates while the toilet lid 32 is in the down position and the toilet flushing device 41 is flushing the toilet and supplying flush water to the toilet body 20, and after the toilet flushing device 41 has flushed the toilet and finished supplying flush water to the toilet body 20.

[0058] [When the seat is used and the automatic closing operation is performed after cleaning] In this case, first, a user enters the toilet room R. Then, the first human body detector 44A detects the user and outputs a first human body detection signal to the controller 51. The controller 51 then causes the toilet lid opening / closing device 49 to perform the toilet lid opening operation. At the same time, the controller 51 turns on the human body detection light emitting unit 44C and activates the deodorizing device 46.

[0059] Next, as shown in Fig. 4, at time T11, the user sits on the toilet seat 31. Then, the seat detection unit 43 detects that the user has sat on the toilet seat 31 and outputs a seat detection signal to the control unit 51. Based on the input of the seat detection signal, the control unit 51 causes the music playback unit to start playing predetermined music.

[0060] Next, at time T12, the user leaves the toilet seat 31. The seating detection unit 43 then detects that the user has left the toilet seat 31 and stops outputting the seating detection signal to the control unit 51. Then, at time T13, a predetermined time (e.g., 6 seconds) has elapsed since time T12, the control unit 51 causes the toilet lid opening / closing device 49 to begin the toilet lid closing operation. At this time, the control unit 51 stops the music playback unit from playing music. At this time, the control unit 51 operates the alarm unit 50 to emit an alarm sound indicating that the toilet lid 32 has begun the toilet lid closing operation. The length of the predetermined time (6 seconds) from time T12 to time T13 can be changed, for example, by operating the remote controller 60.

[0061] Next, at time T14, the toilet lid 32 is placed in a lying position. At this time, a signal corresponding to the angle of the lying toilet lid 32 is input to the control unit 51 from the toilet lid detection unit 45. The control unit 51 then operates the toilet flushing device 41 based on the signal corresponding to the lying position from the toilet lid detection unit 45, causing the supply of flush water to the toilet body 20. At this time, the control unit 51 turns on the sterilization device light-emitting unit, and the sterilization device 47 changes to the operating state. At this time, the sterilization device 47 starts operating from the operating state of its cyclical operation.

[0062] Then, at time T15, the control unit 51 stops the operation of the toilet flushing device 41 and stops the supply of flush water to the toilet body 20. The human body detection light-emitting unit 44C continues to be illuminated by the control unit 51 even after time T15 has passed. The control unit 51 does not perform the toilet lid opening operation for a predetermined time (e.g., 30 seconds) from time T14, even if a first human body detection signal is input from the first human body detector 44A (i.e., even if the control unit 51 detects a user in front of the front end of the toilet body 20 when the toilet lid 32 is in a tilted state). The predetermined time (30 seconds) from time T14 is an invalid period during which the control unit 51 does not accept the first human body detection signal. During the invalid period, the toilet lid 32 can be lifted by the user.

[0063] Next, at time T16, when a predetermined time (for example, 60 seconds) has elapsed since time T12, control unit 51 stops the operation of deodorizing device 46. At this time, control unit 51 turns off human body detecting light emitting unit 44C.

[0064] Next, at time T17, when a predetermined time (for example, 60 seconds) has elapsed since time T14, the control unit 51 changes the sterilization apparatus light emitting unit from a lit state to a blinking state.

[0065] [When operating the remote controller to flush the toilet after use while standing] In this case, first, a user enters the toilet room R. Then, the first human body detector 44A detects the user and outputs a first human body detection signal to the controller 51. The controller 51 then causes the toilet lid opening / closing device 49 to perform a toilet lid opening operation. At the same time, the controller 51 also causes the deodorizing device 46 to operate.

[0066] Next, the user operates the operation button 63A of the remote controller 60, which corresponds to an instruction to open the toilet seat. The control unit 51 then drives the toilet seat opening / closing device 48 to execute the toilet seat opening operation, rotating the toilet seat 31 to an upright position. At this time, the control unit 51 starts playing predetermined music in the music player. The second human body detector 44B can then detect a user in front of the toilet body 20 as the toilet seat 31 rotates to an upright position. A second human body detection signal is input to the control unit 51 from the second human body detector 44B. At the same time, the first human body detector 44A is blocked by the toilet lid 32 and is therefore unable to detect the user, so it stops outputting the first human body detection signal.

[0067] Next, the user operates the operation button 63A of the remote controller 60, which corresponds to the toilet flush instruction. When the control unit 51 receives a wireless signal corresponding to the toilet flush instruction from the remote controller 60 while the second human body detection signal is being input, it operates the toilet flushing device 41 to start supplying flush water to the toilet body 20 while maintaining the toilet seat 31 and toilet lid 32 in the upright position. In other words, when the toilet seat 31 and toilet lid 32 are in the upright position and the second human body detection unit 44B detects a user, if the remote controller 60 is operated, the toilet flushing device 41 performs a toilet flush without causing the toilet seat opening / closing device 48 to perform the toilet seat closing operation of rotating the toilet seat 31 from the upright position to the reclined position, and without causing the toilet lid opening / closing device 49 to perform the toilet lid closing operation.

[0068] Next, the user leaves the toilet room R. This causes the second human body detector 44B to stop outputting the second human body detection signal to the controller 51. When the input of the second human body detection signal stops and a predetermined time (for example, one second) has elapsed, the controller 51 causes the toilet seat opening / closing device 48 and the toilet lid opening / closing device 49 to start the toilet seat closing operation and the toilet lid closing operation. At the same time, the controller 51 causes the music player to stop playing music.

[0069] Furthermore, when a predetermined time (e.g., 60 seconds) has elapsed since the user left the toilet room R, the control unit 51 stops the operation of the deodorizing device 46. At the same time, the control unit 51 causes the sterilization device 47 to start operation from the operating state of the cyclic operation.

[0070] [When using automatic cleaning after use in a standing position] In this case, first, a user enters the toilet room R. Then, the first human body detector 44A detects the user and outputs a first human body detection signal to the controller 51. The controller 51 then causes the toilet lid opening / closing device 49 to perform a toilet lid opening operation. At the same time, the controller 51 also causes the deodorizing device 46 to operate.

[0071] Next, the user operates the operation button 63A of the remote controller 60, which corresponds to the instruction to open the toilet seat 31, causing the toilet seat opening / closing device 48 to perform the toilet seat opening operation. At this time, the control unit 51 causes the music player to start playing a predetermined music. At this time, a second human body detection signal is input from the second human body detector 44B to the control unit 51. At the same time, the first human body detector 44A is blocked by the toilet lid 32 and is no longer able to detect the user, so it stops outputting the first human body detection signal.

[0072] Next, the user leaves the toilet room R. This causes the second human body detector 44B to stop outputting the second human body detection signal to the controller 51. When the input of the second human body detection signal stops and a predetermined time (for example, one second) has elapsed, the controller 51 causes the toilet seat opening / closing device 48 and the toilet lid opening / closing device 49 to start the toilet seat closing operation and the toilet lid closing operation. At the same time, the controller 51 causes the music player to stop playing music.

[0073] Next, the toilet seat 31 and toilet lid 32 are laid down. Then, the control unit 51 operates the toilet flushing device 41 to start supplying flush water to the toilet body 20.

[0074] Furthermore, when a predetermined time (e.g., 60 seconds) has elapsed since the user left the toilet room R, the control unit 51 stops the operation of the deodorizing device 46. At the same time, the control unit 51 causes the sterilization device 47 to start operation from the operating state of the cyclic operation.

[0075] According to the embodiment configured as above, the following effects are achieved.

[0076] The toilet device 30 comprises a toilet lid 32 that is supported so as to be rotatable between an upright position and a reclined position, a toilet flushing device 41 that performs a toilet flush by supplying flush water to the toilet body 20, and a toilet lid opening / closing device 49 that performs a toilet lid closing operation by rotating the upright toilet lid 32 to a reclined position before the toilet flushing device 41 performs a toilet flush. With this configuration, the toilet lid 32 can prevent splashes generated by the toilet flush from reaching the outside of the toilet body 20.

[0077] The toilet device 30 is equipped with a toilet lid detection unit 45 that detects the rotation state of the toilet lid 32, and the toilet flushing device 41 performs toilet flushing after the toilet lid detection unit 45 detects the toilet lid closing operation. With this configuration, the toilet flushing can be started taking into account the rotation state of the toilet lid 32.

[0078] The toilet flushing device 41 of the toilet device 30 executes a toilet flush when the toilet lid detection unit 45 detects an abnormality in the toilet lid closing operation. This configuration makes it possible to avoid situations in which the toilet cannot be flushed due to an abnormality in the operation of the toilet lid 32, and ensures that the toilet flushing can be executed reliably.

[0079] The toilet flushing device 41 of the toilet device 30 performs a toilet flush when a predetermined time has passed since the toilet lid detection unit 45 detected an abnormality in the toilet lid closing operation. This prevents the toilet from being unable to be flushed due to an abnormality in the operation of the toilet lid 32, ensuring that the toilet is flushed reliably.

[0080] The toilet lid opening / closing device 49 of the toilet apparatus 30 has a remote controller 60 (toilet lid operating unit) that commands the execution of a toilet lid-opening operation that rotates the toilet lid 32 from a lying-down state to an upright state. When the toilet lid 32 is lying down and the toilet flushing device 41 is performing a toilet flush and supplying flush water to the toilet body 20, the toilet lid opening / closing device 49 executes the toilet lid-opening operation when the remote controller 60 (toilet lid operating unit) is operated by the user. With this configuration, it is possible to check the status of the toilet flush while the toilet flush is being performed.

[0081] The toilet device 30 includes a toilet seat 31 that is supported so as to be rotatable between an upright position and a reclined position, and a toilet seat opening / closing device 48 that has a remote controller 60 (toilet seat operating unit) that rotates the toilet seat 31 between the upright position and the reclined position and commands the execution of a toilet seat opening operation that rotates the reclined toilet seat 31 to the upright position. The toilet seat opening / closing device 48 executes the toilet seat opening operation when the remote controller 60 (toilet seat operating unit) is operated while the toilet seat 31 is in the reclined position and the toilet flushing device 41 is flushing the toilet and supplying flush water to the toilet body 20. This configuration can improve convenience for the user.

[0082] The toilet device 30 comprises a toilet seat 31 that is supported so as to be rotatable between an upright position and a reclined position, a toilet seat opening / closing device 48 that rotates the toilet seat 31 between the upright position and the reclined position, and a second human body detection unit 44B that detects a user in front of the toilet body 20 when the toilet seat 31 is in the upright position. The toilet flushing device 41 has a remote controller 60 (flush operation unit) that commands toilet flushing. When the toilet seat 31 and toilet lid 32 are in the upright position and the second human body detection unit 44B detects a user, if the remote controller 60 (flush operation unit) is operated, the toilet flushing device 41 performs the toilet seat closing operation by rotating the toilet seat 31 from the upright position to the reclined position, and the toilet lid opening / closing device 49 performs the toilet lid closing operation, and performs the toilet flush. This configuration makes it possible to prevent the toilet lid 32 and toilet seat 31 from falling over when the user is likely to be using the toilet in a standing position.

[0083] The toilet apparatus 30 is equipped with a deodorizing device 46 that deodorizes odors sucked in from the space below the fallen toilet lid 32, and the deodorizing device 46 operates while the toilet lid 32 is in the fallen position and the toilet flushing device 41 is flushing the toilet. With this configuration, the space below the toilet lid 32 can be efficiently deodorized.

[0084] The deodorizing device 46 of the toilet device 30 operates until a predetermined time has elapsed after the toilet flushing device 41 has performed a toilet flush and finished supplying flush water to the toilet body 20. This configuration allows for more reliable deodorization.

[0085] The toilet apparatus 30 is equipped with a sterilization device 47 that releases sterilizing substances below the fallen toilet lid 32. The sterilization device 47 operates while the toilet lid 32 is in the fallen position and the toilet flushing device 41 is flushing the toilet and supplying flush water to the toilet body 20, and after the toilet flushing device 41 has flushed the toilet and finished supplying flush water to the toilet body 20. This configuration can improve the sterilization performance of sterilizing the area below the fallen toilet lid 32.

[0086] The toilet device 30 is equipped with a first human body detector 44A that detects a user in front of the front end of the toilet body 20 when the toilet lid 32 is in a reclined position. When the first human body detector 44A detects a user, the toilet lid opening / closing device 49 performs a toilet lid opening operation to rotate the reclined toilet lid 32 to an upright position, and does not perform the toilet lid opening operation even if the first human body detector 44A detects a user when the toilet lid 32 is in a reclined position and until a predetermined time has elapsed since the toilet flushing device 41 started flushing. This configuration prevents the toilet lid 32 from being in an upright position during toilet flushing, thereby reliably preventing droplets generated during toilet flushing from reaching the surrounding area.

[0087] The toilet device 30 is equipped with a human body detection light-emitting unit 44C that illuminates the area around the toilet body 20 and the inside of the toilet bowl 21, and the human body detection light-emitting unit 44C lights up at least while the toilet flushing device 41 is flushing the toilet after the toilet lid 32 has been placed in a downed position. With this configuration, the time that the area around the toilet body 20 and the inside of the toilet bowl 21 is illuminated can be extended as long as possible.

[0088] The present disclosure is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included within the technical scope of the present disclosure. (1) Unlike the first embodiment, the toilet flushing device may be configured to flush the toilet when the toilet lid detection unit detects that the toilet lid has rotated to a predetermined position before the toilet lid is in the down position after the toilet lid opening / closing device has performed the toilet lid closing operation. Here, the predetermined position is 45° or less, preferably 60° or less, and more preferably 75°, relative to the angle of the toilet lid in the down position. With this configuration, the toilet flush is performed before the toilet lid is in the down position, thereby preventing droplets from the toilet lid from reaching the surrounding area and allowing the toilet to be flushed earlier. (2) Unlike the first embodiment, the sterilization device may be configured to release sterilizing water or ozone having a sterilizing function into the toilet bowl. (3) Unlike embodiment 1, the sterilization device may operate only while the toilet lid is in a down position and the toilet flushing device is flushing the toilet and supplying flushing water to the toilet body, or only after the toilet flushing device has flushed the toilet and finished supplying flushing water to the toilet body. (4) Unlike the embodiment, the notification unit may be configured with an LED, a speaker, a liquid crystal panel, etc., or may be configured using a combination of an LED, a speaker, a liquid crystal panel, and a buzzer. When a speaker or a liquid crystal panel is used, a message such as words or sentences can be notified to the user. Furthermore, the buzzer pattern and the LED light emission pattern may be different between the post-closing operation flush and the pre-closing operation flush. (5) Unlike the first embodiment, the remote controller may detect a human body located in the toilet room. (6) Unlike the first embodiment, the human body detection unit may be configured with other sensors such as an ultrasonic sensor or a heat sensor. (7) Unlike the first embodiment, the seating detection unit may be configured by a capacitance type or weight detection type sensor. (8) Unlike the first embodiment, the toilet body may be a wall-mounted type. (9) Unlike the first embodiment, if the rotation of the toilet lid is obstructed while the toilet lid is closing, the toilet may not be flushed. (10) Unlike the first embodiment, in the post-closing flush, when at least one of the toilet lid and the toilet seat is in the upright position, toilet flushing may be performed immediately upon receiving a toilet flush command from the remote controller. (11) Unlike the first embodiment, when a toilet flush command is issued from the remote controller while at least one of the toilet lid and the toilet seat is closing, the toilet flush may be executed immediately. (12) Unlike in embodiment 1, the human body detection light-emitting unit may be turned off at the time the toilet lid is in the down position, or at any time between the time the toilet lid is in the down position and the time the deodorizing device stops operating. Furthermore, the human body detection light-emitting unit may be turned off after the time the deodorizing device stops operating. (13) Unlike the first embodiment, the human body detecting light emitting unit may be configured to illuminate only the area around the toilet body or the inside of the toilet bowl.
