AI Technical Summary
Existing toilet devices require a long time for the toilet lid to close after a flush command is issued when both the toilet lid and seat are open, and simultaneous closure of both increases power consumption.
The toilet lid and seat are configured to close independently, with the toilet lid closing before the seat when both are open, and the seat closing before the lid when both are closed, at an acute angle.
This configuration reduces the time taken for the toilet lid to close and avoids a temporary increase in power consumption, ensuring quick closure and efficient operation.

Abstract
Description
[Technical Field]
[0001] The present invention relates to a toilet bowl apparatus and a toilet seat apparatus in which the toilet lid and toilet seat are opened and closed independently by electric power. [Background technology]
[0002] Recently, in order to prevent the spread of contaminants contained in excrement when flushing the toilet bowl, it is recommended to flush the bowl with the toilet lid closed after defecating, so that droplets containing contaminants contained in the stool do not scatter outside the bowl.
[0003] In order to ensure that the bowl is flushed with the toilet lid closed, a toilet device has been proposed in which, when a flushing command is received, the toilet lid is first electrically closed by a toilet lid drive unit, and then the bowl is flushed (see, for example, Patent Document 1). [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Application Publication No. 07-158142 Summary of the Invention [Problem to be solved by the invention]
[0005] However, in this type of toilet device, if a flush command is issued and both the toilet lid and the toilet seat are open, the toilet seat is usually closed first before the toilet lid closing operation begins, so it takes a long time from the flush command to the toilet lid closing.Note that Patent Document 1 describes closing the toilet lid when the toilet lid is open and the user is not sitting on it, but does not explain the operation when both the toilet lid and the toilet seat are open.
[0006] Another method that can be considered to shorten the time is to close the toilet seat and toilet lid simultaneously. However, since the amount of electricity required to drive the toilet seat and toilet lid (start the closing operation) and close them separately increases, the amount of electricity required increases even more when they start or close at the same time, which could have a negative impact on the machinery (motor, etc.).
[0007] The present invention was proposed in consideration of these circumstances, and its purpose is to provide a toilet bowl device and toilet seat device that does not require a long time for the toilet lid to close when a flushing command is given, and that can avoid an increase in power consumption. [Means for solving the problem]
[0008] In order to achieve the above object, the toilet device of the present invention is a toilet device comprising a bowl, a toilet flushing unit that supplies flushing water to the bowl to flush the inside of the bowl, a toilet lid, a toilet lid open / close detection unit that detects the opening and closing of the toilet lid, a toilet seat, a flushing instruction means that outputs a flushing instruction to the toilet flushing unit, and a control unit, wherein the toilet lid and the toilet seat are configured to be opened and closed independently by electric power, and when a flushing instruction is given by the flushing instruction means, if the toilet lid is open, the toilet lid closing operation is initiated before flushing by the toilet flushing unit, while if the toilet lid is closed, flushing by the toilet flushing unit is carried out, and the control unit is characterized in that, when the toilet lid and the toilet seat are open when the flushing instruction is received, the control unit starts the closing operation of the toilet seat, and then starts the closing operation of the toilet lid before the toilet seat closes, causing the toilet lid to close so that it follows the toilet seat at an acute angle.
[0009] The toilet seat device of the present invention is a toilet seat device that is attached to the toilet bowl body and includes a toilet seat, a toilet lid, a toilet lid opening / closing detection unit that detects the opening / closing of the toilet lid, a bowl flushing instruction means that receives flushing instructions for the toilet bowl body, and a toilet seat side control unit, and is configured to open and close the toilet lid and the toilet seat independently by electric power, and when a flushing instruction is given by the bowl flushing instruction means, if the toilet lid is open, the toilet lid closing operation is initiated before a flushing instruction is output to the toilet bowl body, while if the toilet lid is closed, the toilet seat side control unit is configured to output a flushing instruction to the toilet bowl body, and when the toilet lid and the toilet seat are open when the flushing instruction is received, the toilet seat side control unit starts the closing operation of the toilet seat, and then starts the closing operation of the toilet lid before the toilet seat closes, causing the toilet lid to follow the toilet seat at an acute angle. [Effects of the Invention]
[0010] Since the toilet bowl device and toilet seat device of the present invention are configured as described above, when a flushing command is given and the toilet seat and toilet lid are closed, it does not take a long time for the toilet lid to close, and an increase in power consumption can be avoided.

[Figure 5] FIG. 1(a) is a basic block diagram of a toilet device and a toilet seat device used therein according to another embodiment of the present invention, and FIG. 1(b) is a schematic side view showing the interior of the toilet device. DETAILED DESCRIPTION OF THE INVENTION
[0012] An embodiment of the present invention will be described below with reference to the accompanying drawings. The toilet apparatuses 1 and 3 described below are designed to flush the bowl 12 with the toilet lid 20 closed, in principle, in order to prevent the spread of contaminants contained in excrement. Therefore, if the toilet lid 20, 40 is not closed when a flush command is issued, the toilet lid 20, 40 is normally closed automatically and electrically before flushing in order to close the toilet lid 20, 40. Hereinafter, the closing of the toilet lid 20, 40 and the subsequent flushing will be referred to as the sequence operation.
[0013] First, an outline of the basic configuration of the toilet apparatus 1 according to this embodiment will be described below. This toilet apparatus 1 is an apparatus having the configuration exemplified in Figures 1 and 2, and performs the operations shown in Figures 3 and 4.
[0014] The toilet device 1 comprises a bowl 12, a toilet flushing unit 13 that supplies flushing water to the bowl 12 to flush the inside of the bowl 12, a toilet lid 20, a toilet lid open / close detection unit 21 that detects whether the toilet lid 20 is open or closed, and a toilet seat 24. The toilet device 1 further comprises a flushing instruction means that outputs flushing instructions to the toilet flushing unit 13, and a control unit 5.
[0015] The toilet lid 20 and the toilet seat 24 are configured to be opened and closed electrically independently, and when a cleaning command is given by the cleaning command means, if the toilet lid 20 is open, the closing operation of the toilet lid 20 is started before cleaning by the toilet bowl cleaning unit 13, whereas if the toilet lid 20 is closed, cleaning by the toilet bowl cleaning unit 13 is carried out.
[0016] Then, if the toilet lid 20 and the toilet seat 24 are open when the control unit 5 receives a flushing command, it starts the closing operation of the toilet seat 24, and then executes a control operation to start the closing operation of the toilet lid 20 before the toilet seat 24 closes. Next, the detailed configuration, structure and basic operation of the toilet device 1 will be described.
[0017] Figures 1 to 4 are explanatory diagrams of a toilet apparatus 1. Note that Figures 2(a) and 2(b) are schematic side views showing the interior of toilet apparatus 1 in two forms with different flushing methods (structures), and either method may be used.
[0018] The toilet device 1 is a seat-type Western-style toilet device that is fixed to the floor or wall of a toilet space. The main body 10 of this toilet device 1 is built so that the bowl 12, which opens upward, is surrounded by a skirt part 11, and above the bowl 12 are provided a toilet seat 24 and a toilet lid 20, which are arranged on the same axis of rotation and can be raised or lowered relative to the opening of the bowl 12. However, they may also be arranged on separate axes of rotation so that they can be linked together.
[0019] A toilet flushing unit 13 is disposed in the internal space of the skirt unit 11, which drains wastewater from the bowl 12 and supplies flushing water from a water supply port 14 into the bowl 12 to clean the inside of the bowl 12. This toilet flushing unit 13 has a water supply mechanism and a drainage mechanism.
[0020] The water supply mechanism includes a water inlet 14, a flushing water supply path 15 that supplies flushing water from a water pipe (not shown) into the bowl 12 through the water inlet 14, and a water supply valve 16 located midway along the flushing water supply path 15 that supplies or cuts off the water supply to the bowl 12.
[0021] The drainage mechanism shown in Figure 2(a) has a cylindrical, curved trap 17 that is connected to extend rearward from the bottom of bowl 12, and trap 17 extends further downward and connects to drain port 18. This type of drainage mechanism includes the siphon type, siphon jet type, and siphon vortex type, and is a mechanism that creates a drainage state or a water-sealed state by the siphon action.
[0022] The drainage mechanism may also have a structure having a movable trap 17A as shown in Figure 2(b). This trap 17A is rotated in the direction of the arrow by a drive unit (not shown) to set the drainage state or the water-sealing state. In the illustrated example, trap 17A is in the water-sealing state, and in the drainage state, it rotates so that the open end of trap 17A faces drain outlet 18. Trap 17A is enclosed in a trap case (not shown) to prevent sewage and odors from leaking to the outside.
[0023] Furthermore, a drainage mechanism that is neither a siphon type nor a movable type, such as a wash-down type drainage mechanism, can also be applied to the toilet device 1.
[0024] In addition, in the illustrated example, the toilet device 1 is shown as a tankless type that is directly connected to the water supply and does not have a flush tank (low tank), but it may also be configured to have a flush tank.
[0025] 1, in addition to the toilet lid open / close detection unit 21 described above, the toilet device 1 also includes a toilet lid drive unit 22 and a toilet lid operation unit 23 that receives open / close instructions from the user to the toilet lid drive unit 22. The toilet device 1 also includes a toilet seat 24, a toilet seat open / close detection unit 25 that detects whether the toilet seat 24 is open or closed, a toilet seat drive unit 26 that opens and closes the toilet seat 24, a toilet seat operation unit 27 that receives open / close instructions to the toilet seat drive unit 26, and also includes a seating detection unit 28.
[0026] The toilet lid operating unit 23 and the toilet seat operating unit 27 may each be configured with separate switches for opening and closing, or may be configured to alternate between opening and closing with a single switch. In the latter case, the toilet lid open / close detection unit 21 (toilet seat open / close detection unit 25) and software may work together to determine whether the command is to open or close.
[0027] The seating detection unit 28 may be, for example, a load sensor that is built into the toilet seat 24 and detects whether the user is sitting or leaving the seat, or an infrared sensor that detects whether the user is sitting or leaving the seat near the rotation axis of the toilet seat 24. The toilet lid open / close detection unit 21 and the toilet seat open / close detection unit 25 may be configured to detect the open / closed state based on the opening angle.
[0028] The toilet lid drive unit 22 and the toilet seat drive unit 26 are each composed of a motor, etc. The toilet lid drive unit 22 electrically opens and closes (raises and lowers) the toilet lid 20 when instructed to do so by the toilet lid operation unit 23, and the toilet seat drive unit 26 electrically opens and closes (raises and lowers) the toilet seat 24 when instructed to do so by the toilet seat operation unit 27. In the example shown in Figure 1, the toilet lid 20 and the toilet seat 24 each have a drive unit (motor), but they may also be configured to be driven individually by a single motor.
[0029] In this specification, for both the toilet lid 20 and the toilet seat 24, a state in which they are upright in an approximately vertical position is referred to as the open state, and a state in which they are tilted approximately horizontally and approximately parallel to the opening surface of the bowl 12 is referred to as the closed state.
[0030] In this toilet apparatus 1, if the toilet lid 20 and toilet seat 24 are both open when a command to close the toilet lid 20 is given by the toilet lid operating unit 23 or the like, the toilet seat 24 will close first, and then the toilet lid 20 will close in conjunction with the closing of the toilet seat 24. When this toilet apparatus 1 receives a flushing command, it executes the sequence operations described above, and if the toilet seat 24 is open at that time, the closing operations will be executed in the order of the toilet seat 24 and the toilet lid 20. Details of this operation will be described later in conjunction with the explanation of Figures 3 and 4.
[0031] Also, if the toilet seat 24 and the toilet lid 20 are both in a closed state when an instruction to open the toilet seat 24 is given by the toilet seat operating unit 27 or the like, the toilet lid 20 first performs an opening operation, and then the toilet seat 24 performs an opening operation in conjunction with the opening operation of the toilet lid 20.
[0032] The toilet apparatus 1 may further be configured to include various functional devices such as a deodorizing device that deodorizes the inside of the bowl 12, a heating device that warms the toilet seat 24, and a private parts washing device that washes the private parts.
[0033] The toilet apparatus 1 further includes a flushing operation unit 29. This flushing operation unit 29 includes a defecation flush button 29a and a urination flush button 29b that output flushing instructions to the toilet flushing unit 13 via the control unit 5, which will be described later.
[0034] It is desirable that the cleaning operation unit 29 be provided on both the main body operation unit (not shown) and the remote control (not shown). These are provided with operation switches and operation buttons for various operations and settings. An infrared communication remote control is preferably used. It goes without saying that the remote control is provided with a transmitting unit (not shown) and the main body 10 is provided with a receiving unit (not shown).
[0035] The operation of the flush operating unit 29 acts as a flush instruction means, but the change in state from seated to up, detected by the seat detection unit 28, also acts as a flush instruction means. In other words, when a person stands up from the toilet seat 24 while seated, an automatic flush is performed instead of operating the flush button.
[0036] Furthermore, a configuration may be adopted in which a flush command is output by a single flush button, without providing both the stool flush button 29a and the urination flush button 29b. In other words, in this case, the amount of flush water into the bowl 12 is not differentiated between a large volume for stool and a small volume for urination, but is limited to only one type, a large volume for stool.
[0037] The toilet device 1 is equipped with a control unit 5 that controls the above-mentioned controlled objects (such as the water supply valve 16 of the toilet flushing unit 13, the toilet lid drive unit 22, and the toilet seat drive unit 26), while also receiving output signals from the flushing operation unit 29, the toilet lid open / close detection unit 21, the toilet seat open / close detection unit 25, and the seating detection unit 28. This control unit 5 is composed of a processor such as a CPU or MPU, and various programs. The toilet device 1 also has a timer 6 and a power supply unit (not shown).
[0038] The toilet device 1 also includes a notification unit 7 that includes a speaker or other device that notifies the user of device abnormalities, status, and guidance using sound or voice synthesis. The notification unit 7 may also include a display such as an LED instead of or in addition to a sound output device.
[0039] Next, the basic operation of this toilet apparatus 1 will be explained based on the operation flowchart in Figure 3 and the schematic operation explanatory diagram of the toilet seat 24 and toilet lid 20 in Figure 4. This operation is performed by the control unit 5 when a flush command is issued by the flush command means. Note that in the schematic operation explanatory diagrams shown in Figures 4(a) to (e), for convenience of illustration, the toilet seat 24 and toilet lid 20 are shown as having different rotation axes (marked with an x in Figure 4), but as mentioned above, they may also have the same rotation axis.
[0040] In the following explanation of operation, the open / closed state of the toilet lid 20 and the open / closed state of the toilet seat 24 are detected by the various detectors, but the explanation of the operation of these detectors will be omitted. Also, the opening and closing operations of the toilet lid 20 and the toilet seat 24 are performed by the various drive units, but the explanation of the operation of these drive units will be omitted.
[0041] 3 will be described with reference to the flowchart shown in steps S100 to S110. In the following description, "Step Sxxx" will be abbreviated to "Sxxx" with only the reference numeral.
[0042] When a flush command is received from the flush command means, the notification unit 7 first notifies the user of this, for example by making an electronic beep (S100, S101).Then, the open / closed state of the toilet lid 20 is determined, and if it is closed, the bowl 12 is immediately flushed (N in S102, S109).
[0043] Although not shown in Figure 3, after the cleaning in S109 is completed, the toilet lid 20 opens, and after a certain period of time after it has been in the open state, the toilet lid 20 closes, and is then placed in a standby state (the toilet lid 20 is closed).
[0044] This action of opening the toilet lid 20 after flushing is an action that is performed so that the user can check whether any waste remains in the bowl 12 after flushing. In other words, the user does not need to manually open the toilet lid 20 to check the inside of the bowl 12 after flushing.
[0045] Instead of delaying for a certain period of time, the toilet may return to the standby state when the motion sensor no longer detects a person. Of course, the toilet lid 20 can be closed by the user using the toilet lid operating unit 23, so it is not necessary to automatically return to the standby state.
[0046] Furthermore, if the toilet lid 20 is in the open position when the flushing command is received, the open / closed state of the toilet seat 24 is further determined (Y in S102, S103). If the toilet seat 24 is in the open position, the closing operation of the toilet seat 24 is initiated, and after a predetermined time has elapsed, the closing operation of the toilet lid 20 is initiated (Y in S103, S104 to S106, and Figures 4(a) and (b)).
[0047] In this case, the toilet seat 24 and toilet lid 20 should close so that the toilet lid 20 follows the toilet seat 24 at an acute angle, as shown in Figures 4(a) and 4(b). The angle difference should be smaller than the angle difference between the state in which the toilet lid 20 is upright and the state before the toilet seat 24 is closed, and an angle of about 5 to 20 degrees is considered preferable to achieve rapid closing of both. Of course, an angle difference of more than 20 degrees is also acceptable. Note that, to prevent the start of the toilet lid 20 opening operation and the stop of the toilet seat 24 from overlapping, it is desirable to set the upper limit of the angle difference to about 70 degrees.
[0048] As in this example, such an angle difference can be achieved by a time delay using the timing unit 6, and the delay time can be calculated from the time it takes for the toilet seat 24 to be in the upright position and closed. For example, the delay time can be about 1 / 4 to 1 / 3 of the time it takes for the toilet seat 24 to be in the upright position and closed.
[0049] It should be noted that the timing for starting the closing operation of the toilet lid 20 may be determined by detecting the drive angle of the toilet seat 24, rather than by using such a time difference.
[0050] The toilet seat 24 and toilet lid 20 continue to close individually as shown in Figures 4(b) and (c), with the toilet seat 24 closing first as shown in Figure 4(d), and then the toilet lid 20 closing as shown in Figure 4(e).
[0051] When the toilet lid 20 is closed, a different electronic sound, such as a beep, is emitted to indicate that the toilet lid 20 is closed, and the bowl 12 is flushed (S107-S109). Note that instead of indicating that the toilet lid 20 is closed, a notification that a flush will be performed may be emitted. In that case, a notification is also emitted when the toilet lid 20 is closed after a flush command is issued (N in S102).
[0052] Furthermore, if the toilet lid 20 is open and the toilet seat 24 is closed when a flushing command is received, it is determined whether or not the user is sitting on the toilet, and if not, the toilet lid 20 is closed, a notification is given when the toilet seat is closed, and flushing is performed (N in S110, S106 to S109).If the user is sitting on the toilet, flushing begins immediately (Y in S110, S109).
[0053] As described above, when a flushing command is received while the toilet lid 20 is open, the sequence operation is executed, but if the toilet seat 24 is also open at that time, the toilet seat 24 and toilet lid 20 are closed in sequence at the angle difference as described above.
[0054] In this way, instead of waiting for the toilet seat 24 to close before starting the closing operation of the toilet lid 20, the toilet lid 20 follows the toilet seat 24 at a predetermined angle. As a result, the process from the start of the closing operation of the toilet seat 24 to the closing of the toilet lid 20 is carried out quickly, and flushing after a flushing command is issued is carried out quickly without having to wait.
[0055] Furthermore, since the closing operations of the toilet seat 24 and toilet lid 20 are not simultaneous but occur at different times, there is no risk of the start or stop (closing) timings of the closing operations overlapping, and there is no risk of a temporary increase in the amount of electricity consumed, making it unlikely that this will have any adverse effects on the machine.
[0056] Furthermore, as described above, the closing operation of the toilet lid 20 begins before the toilet seat 24 is closed, so there is no risk of the timing of the start of the opening operation of the toilet lid 20 overlapping with the stopping of the toilet seat 24, thereby avoiding a temporary increase in the amount of electricity used.
[0057] Also, when the closing operation is performed by the toilet lid operating unit 23, the operating sequence may be such that the toilet seat 24 closes and then the toilet lid 20 starts closing, or the operating sequence may be with a time lag similar to when a flushing command is received, as described above.
[0058] Furthermore, when an opening operation is performed using the toilet seat operating unit 27, the toilet lid 20 may be opened first, followed by the toilet seat 24 starting to open, or the toilet lid 20 and toilet seat 24 may be opened with a time lag. In this case, the angle difference may be around 5 to 20 degrees.
[0059] Furthermore, the toilet apparatus 1 is not limited to the above, and may be one in which the toilet seat 24 and toilet lid 20 are replaceable as a single unit. In particular, it may be a toilet apparatus 3 to which a toilet seat apparatus 30 as shown in Figure 5 has been retrofitted (or replaced). The basic structure of a toilet apparatus 3 according to another embodiment of the present invention will be described with reference to Figures 5(a) and (b). Note that in this embodiment, a movable trap 17A is shown as an example in Figure 5(b), but the present invention can also be applied to toilets in which the toilet body has a siphon-type trap 17 (see Figure 2(a)) or other types.
[0060] Specifically, the toilet device 3 includes a bowl 12, a toilet flushing unit 13 that supplies flushing water to the bowl 12 to flush the inside of the bowl 12, a toilet seat device 30, a flushing operation unit 29 that outputs flushing instructions to the toilet flushing unit 13, a control unit 5, a timing unit 6, and an alarm unit 7.
[0061] The toilet seat device 30 is a separate, detachable unit from the toilet body (portions excluding the toilet seat device 30) of the toilet device 3. The toilet seat device 30 is equipped with a toilet lid 40, a toilet lid open / close detection unit 41, a toilet lid drive unit 42, a toilet lid operation unit 43, a toilet seat 44, a toilet seat open / close detection unit 45, a toilet seat drive unit 46, a toilet seat operation unit 47, a seating detection unit 48, a bowl flush operation unit 49, a toilet seat side control unit 35, a timing unit 36, and an alarm unit 37. Electrical signals can be sent and received between the toilet seat device 30 and the toilet body.
[0062] The configuration of the toilet device 3 (toilet body) excluding the toilet seat device 30 is generally the same as that shown in Figure 1, so detailed explanation will be omitted. In addition, the toilet seat device 30 includes a toilet lid 40, a toilet lid open / close detector 41, a toilet lid drive unit 42, a toilet lid operation unit 43, a toilet seat 44, a toilet seat open / close detector 45, a toilet seat drive unit 46, a toilet seat operation unit 47, and a seating detector 48, which are generally the same as those shown in Figure 1, so explanations thereof will be omitted.
[0063] The toilet seat device 30 in Figure 5 is configured so that an instruction to flush the bowl 12 can be output from the toilet seat device 30 to the toilet flushing unit 13. Specifically, when a flushing instruction is received from the bowl flush operating unit 49, the toilet seat-side control unit 35 of the toilet seat device 30 receives this instruction and controls the toilet flushing unit 13 via the control unit 5 on the toilet body side to flush the bowl 12. Alternatively, the toilet seat-side control unit 35 may be configured to directly control the toilet flushing unit 13.
[0064] As shown in Figure 5, the toilet apparatus 3 is configured to include not only the bowl flush operation unit 49 on the toilet seat apparatus 30 side, but also the flush operation unit 29 on the toilet body side. In other words, the toilet apparatus shown in Figure 5 is configured so that flush commands can be issued using either the flush operation unit 29 or the bowl flush operation unit 49. It is also possible to configure the toilet without providing the flush operation unit 29 on the toilet body side, so that flush commands can be issued only using the bowl flush operation unit 49. It is also desirable that the bowl flush operation unit 49 also has a stool flush button and a urination flush button.
[0065] Operation of bowl flush operating unit 49 acts as a bowl flush command means, but a change in state from seated to up, detected by seat detection unit 48, also acts as a bowl flush command means. In other words, when a person stands up from toilet seat 44 while seated, automatic flushing is performed instead of operating the flush button.
[0066] Like the toilet apparatus 1 in Fig. 1, this toilet apparatus 3 is capable of the operations shown in Fig. 3 and Fig. 4. In other words, when a flushing command is received from the bowl flushing command means, the toilet flushing unit 13 will, in principle, flush the bowl 12 with the toilet lid 40 closed. If the toilet seat 44 and toilet lid 40 are both open when a flushing command is received, the toilet seat 44 and toilet lid 40 will close at different angles as shown in Fig. 4, and flushing will occur after the toilet lid 40 is closed.
[0067] As described above, the toilet seat device 30 comprises the toilet seat 44, the toilet lid 40, and the toilet lid open / close detection unit 41 that detects whether the toilet lid 40 is open or closed. The toilet seat device 30 is also a device that is attached to the toilet body, and is equipped with a bowl flush command means that receives flush commands for the toilet body, and a toilet seat-side control unit 35. The toilet seat device 30 is configured to electrically open and close the toilet lid 40 and the toilet seat 44 separately. When a flush command is received from the bowl flush command means, if the toilet lid 40 is open, the toilet seat device 30 is configured to start the closing operation of the toilet lid 40 before outputting a flush command to the toilet body, but if the toilet lid 40 is closed, it outputs a flush command to the toilet body.
[0068] If the toilet lid 40 and toilet seat 44 are open when the toilet seat-side control unit 35 receives a flush command, it will start the closing operation of the toilet seat 44, and then execute a control operation to start the closing operation of the toilet lid 40 before the toilet seat 44 closes. In this way, the toilet device 3 can achieve time-delayed operation of the toilet lid 40 and toilet seat 44 by the toilet seat device 30 and the toilet body working together.
[0069] The toilet seat device 30 is not limited to that shown in Figure 5. For example, the toilet seat device 30 may be configured to include a private parts washing device, or may be configured to include a toilet seat operating unit (not shown) that can perform various operations and settings (for example, the private parts washing device).
