Technical Field

[0001] The present invention relates to a toilet device having a toilet lid and a toilet lid driving unit, and a toilet seat device having the toilet lid and the toilet lid driving unit which is mounted on a toilet body for use. Background Art

[0002] Recently, from the perspective of preventing the spread of pollutants contained in excrement during toilet cleaning, in order to prevent droplets of pollutants contained in feces excreted into the bowl from flying outside the toilet, it is recommended to clean the toilet bowl with the toilet lid closed after excretion.

[0003] In order to reliably perform such toilet bowl cleaning with the toilet lid closed, a toilet device has been proposed in which, when a cleaning instruction is given, the toilet lid is first electrically closed by a toilet lid driving unit and then the toilet bowl is cleaned (for example, see Patent Document 1).

[0007] Problems to be solved by the invention

[0008] However, toilet flushing in toilets includes not only flushing performed when the flushing control unit is operated during defecation or urination, or when the toilet seat is left, but also automatic flushing that is performed regularly or irregularly, regardless of the timing of defecation or urination. Timer flushing includes, for example, automatic cleaning (flushing) performed at a predetermined time, such as when the toilet has not been flushed for six hours.

[0009] Therefore, if the toilet device performs a sequence of actions consisting of closing the toilet lid and then flushing the toilet bowl when a flushing instruction is issued, such a sequence of actions will be performed even in the case of scheduled flushing.

[0010] However, sometimes the timer flushing timing coincides with the user's toilet usage, potentially causing problems. For example, if a man urinates while standing and the timer flushing timing coincides, the user cannot urinate because the toilet lid must be closed during the timer flushing sequence. In particular, if the timer flushing timing occurs while the user is urinating, the moving toilet lid can interfere with urination, and the user's panic can cause urine to splash onto the lid or the floor.

[0011] The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a toilet device and a toilet seat device that can suppress interference with user use caused by automatic flushing set by a timer.

[0032] The following describes an embodiment of the present invention with reference to the accompanying drawings. The toilet devices 1 and 3 described below, in principle, clean the toilet bowl 12 with the toilet lid 20 closed, to prevent the spread of pollutants contained in excrement. Therefore, when a cleaning instruction is issued, while the toilet lid 20, 40 is in the process of opening, the toilet lid drive unit 22, 42 is permitted to initiate closing of the toilet lid 20, 40, and then, after detecting the closed state of the toilet lid 20, 40, the toilet cleaning unit 13 performs a cleaning operation. The cleaning instruction issued by the cleaning instruction unit includes a cleaning instruction set by a timer.

[0033] In the first embodiment, when a cleaning instruction based on a timer setting is issued, the control unit 5 prohibits the above-described sequence of operations (closing the toilet lid 20 and subsequent cleaning) when the toilet lid 20 is open, and causes the toilet cleaning unit 13 to clean the toilet bowl 12 regardless of the open or closed state of the toilet lid 20. Furthermore, in another aspect of this embodiment, the control unit 5 is configured such that, when a cleaning instruction based on a timer setting is issued, the control unit 5 prohibits the above-described sequence of operations when the toilet lid 20 is open, cancels the cleaning instruction, and changes the timer setting.

[0034] In the second embodiment, the control unit 5 is configured to prohibit the sequential operation when a person or an object is detected by the obstacle detection unit 28 at the timing of the cleaning instruction set by the timer.

[0035] In the third embodiment, when a washing instruction is issued based on a timer setting, the control unit 5 causes the notification unit 7 or the toilet seat-side notification unit 37 to notify execution of the sequence operation based on the timer setting before executing the sequence operation.

[0036] First, the following describes the common matters of the toilet apparatus 1 of the first to third embodiments. These toilet apparatuses 1 are independent apparatuses, but the basic structure of the apparatus is substantially the same. Figure 1 、 Figure 2 To explain the outline.

[0037] This toilet device 1 includes a toilet bowl 12, a toilet washing unit 13 that supplies washing water to the toilet bowl 12 and cleans the interior of the toilet bowl 12, a toilet lid 20, a toilet lid opening / closing detection unit 21 that detects whether the toilet lid 20 is opened or closed, and a toilet lid driving unit 22 that opens and closes the toilet lid 20. Furthermore, this toilet device 1 includes a washing instruction unit that outputs a washing instruction to the toilet washing unit 13, an obstacle detection unit 28 that detects people or objects near the toilet bowl 12, a timer unit 6, and a control unit 5. The washing instruction unit includes a unit that operates in response to a washing operation by the user and a unit that operates automatically in response to the user's actions, which will be described in detail later.

[0038] When a cleaning instruction is issued by the cleaning instruction unit, the toilet device 1 allows the toilet lid 20 to be closed by the toilet lid driving unit 22 while the toilet lid 20 is in the process of being opened, and then performs a cleaning operation of the toilet cleaning unit 13 after the closed state of the toilet lid 20 is detected.

[0039] Next, the detailed structure, construction, and basic operation of the toilet apparatus 1 will be described.

[0040] Figure 1 This is a basic block diagram of the toilet device 1. Figure 2 (a) and Figure 2 (b) is a schematic side view schematically showing the interior of the toilet apparatus 1 in two forms having different flushing methods (structures), and any form may be adopted.

[0041] The toilet apparatus 1 is a Western-style toilet apparatus with a seat that is fixed to the floor or wall within the restroom space. The toilet apparatus 1 comprises a main body 10, which houses an upwardly open toilet bowl 12 surrounded by a skirt 11. The toilet apparatus 1 also includes a toilet seat 24 and a toilet lid 20, each of which can be freely raised and lowered to cover the open surface of the toilet bowl 12.

[0042] A toilet flushing unit 13 is disposed in the interior of the skirt 11. The toilet flushing unit 13 drains dirty water from the toilet bowl 12 and supplies flushing water from a water supply port 14 into the toilet bowl 12 to flush the inside of the toilet bowl 12. The toilet flushing unit 13 includes a water supply mechanism and a drainage mechanism.

[0043] The water supply mechanism includes: a water supply port 14; a cleaning water supply passage 15, which supplies cleaning water supplied from a tap water pipe (not shown) into the toilet bowl 12 through the water supply port 14; and a water supply valve 16, which is arranged in the middle of the cleaning water supply passage 15 to supply or cut off the water supply to the toilet bowl 12.

[0044] Figure 2 The drainage mechanism shown in (a) has a cylindrical curved trap 17 connected so as to extend rearward from the bottom of the toilet bowl 12. The trap 17 further extends downward and is connected to a drain outlet 18. Examples of such drainage mechanisms include siphon type, jet siphon type, and vortex siphon type, which form a drainage state or a water-sealed state through siphon action.

[0045] In addition, as a drainage mechanism, it can also have Figure 2(b) shows the structure of a movable return bend 17A. This return bend 17A is rotated in the direction of the arrow by a drive unit (not shown) to establish a draining state or a water-sealing state. The return bend 17A shown in the figure is in the water-sealing state. In the draining state, it rotates so that the open end of the return bend 17A faces the drain outlet 18. Furthermore, the return bend 17A is surrounded by a return bend housing (not shown) to prevent wastewater and odors from leaking to the outside.

[0046] In addition, a drainage mechanism other than the siphon type or the movable type, for example, a flush type drainage mechanism may be applied to the toilet apparatus 1 .

[0047] In the example shown, the toilet apparatus 1 is a tankless type that does not include a flush tank (low tank) and is directly connected to a water pipe. However, a configuration including a flush tank may be employed.

[0048] In addition, as described above, the toilet device 1 can also Figure 1 As shown, the toilet apparatus 1 includes a toilet lid opening / closing detection unit 21 and a toilet lid driving unit 22, and further includes a toilet lid operating unit 23 for receiving an opening / closing instruction from the user to the toilet lid driving unit 22. Furthermore, the toilet apparatus 1 includes a toilet seat 24, a toilet seat opening / closing detection unit 25 for detecting the opening / closing of the toilet seat 24, a toilet seat driving unit 26 for opening / closing the toilet seat 24, and a toilet seat operating unit 27 for receiving an opening / closing instruction to the toilet seat driving unit 26.

[0049] The toilet apparatus 1 also includes a seat occupancy detector 28a and a human body detector 28b. These seat occupancy detector 28a and human body detector 28b constitute the aforementioned obstruction detection unit 28. The obstruction detection unit 28 detects a person or object that is blocking the closing of the toilet lid 20. Examples of the obstruction detection unit 28 include various mechanisms that detect a person (person) urinating in a standing position, urine (or object) being discharged, a user (person) checking feces in the toilet bowl 12 with the toilet lid 20 open, or cleaning tools (or objects) placed in the toilet bowl 12.

[0050] Therefore, the obstacle detection unit 28 is not limited to the seat occupancy detection unit 28a and the human body detection unit 28b, but may include detection units installed in various other locations. Examples of sensors constituting the detection unit of the obstacle detection unit 28 include pyroelectric sensors, wireless sensors, ultrasonic sensors, infrared sensors, and load cells.

[0051] The seat occupancy detection unit 28a detects the seating / leaving status of the toilet seat 24 and employs, for example, a load sensor built into the toilet seat 24 or an infrared sensor that detects seating / leaving from near the rotating shaft of the toilet seat 24. The human body detection unit 28b detects the presence of a person in the toilet and employs, for example, a pyroelectric sensor that detects heat generated by a person.

[0052] Furthermore, as the toilet lid opening / closing detection unit 21 and the toilet seat opening / closing detection unit 25, a configuration for detecting an opening / closing state based on an opening angle is appropriately adopted.

[0053] 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 in response to instructions from the toilet lid operation unit 23, and the toilet seat drive unit 26 electrically opens and closes (raises and lowers) the toilet seat 24 in response to instructions from the toilet seat operation unit 27.

[0054] In this specification, the state in which either the toilet lid 20 or the toilet seat 24 is erected in a generally vertical position is referred to as the open state, while the state in which the toilet lid 20 is tilted in a generally horizontal position and approximately parallel to the opening of the toilet bowl 12 is referred to as the closed state. Furthermore, the closed state of the toilet lid 20 may include not only the fully closed state but also the state in which the toilet lid 20 is approximately blocking the opening of the toilet bowl 12 just before the closing operation. For example, the closed state may be determined when the angle between the toilet lid 20 and the opening of the toilet bowl 12 is less than 5 degrees. Furthermore, instead of defining the closed state of the toilet lid 20 within such an angle range, the closed state may be defined within a predetermined time range after the start of the closing operation.

[0055] In this toilet apparatus 1, when the toilet lid 20 is instructed to close via the toilet lid operating unit 23 or the like, and both the toilet lid 20 and the toilet seat 24 are in the open state, the toilet seat 24 closes first, and after it is completely closed (stops in the closed state), the toilet lid 20 closes in conjunction with the closing of the toilet seat 24. Alternatively, the closing of the toilet lid 20 may be initiated at a timing when both the toilet seat 24 and the toilet lid 20 are in the closed state immediately before being completely closed.

[0056] When an instruction to open the toilet seat 24 is issued via the toilet seat operating unit 27 or the like, if both the toilet seat 24 and the toilet lid 20 are closed, the toilet lid 20 opens first. At a timing after the toilet lid 20 is fully opened (stopped in the open state) or immediately before it is fully opened, the toilet seat 24 opens in conjunction with the opening of the toilet lid 20.

[0057] The toilet apparatus 1 may be configured to include various functional devices such as a deodorizing device for deodorizing the inside of the toilet bowl 12, a heating device for heating the toilet seat 24, and a local cleaning device for cleaning the local area.

[0058] The toilet apparatus 1 further includes a flushing operation unit 29. The flushing operation unit 29 includes a feces flushing button 29a and a urine flushing button 29b, which output flushing instructions to the toilet flushing unit 13 via the control unit 5 described later.

[0059] In addition, it is preferable to configure a cleaning operation unit 29 in both the main operating unit (not shown) and the remote control (not shown). These are also provided with operation switches and operation buttons for performing various operations and settings. Infrared communication remote controls are suitable as remote controls. Of course, the remote control is provided with a transmitter (not shown), and the main unit 10 is provided with a receiver (not shown).

[0060] Operation of the flush operation unit 29 functions as a flush instruction unit. Furthermore, the trigger of a change from a seated state to an unseated state detected by the seat occupancy detector 28a also functions as a flush instruction unit. That is, when a person stands up from the toilet seat 24 while seated, flushing is executed instead of operating the flush button.

[0061] Alternatively, instead of providing both the defecation flushing button 29a and the urination flushing button 29b, a single flushing button may be used to output a flushing instruction. In other words, in this case, the flushing water volume supplied to the toilet bowl 12 is not differentiated into a large volume for defecation and a small volume for urination, but only a large volume for defecation.

[0062] The toilet apparatus 1 also includes a timer flush setting unit 8. This unit is used to set a timer flushing function, such as a regular toilet flushing function or an automatic cleaning function, that is executed independently of the user's defecation or urination. Timer flushing automatically cleans the toilet bowl 12 after a long period of non-use, such as six hours, or at a set time. This function is executed through the collaboration of the control unit 5, the timer unit 6, and the toilet flushing unit 13.

[0063] For example, automatic cleaning can be performed at 24-hour intervals or 6-hour intervals when the device is not used at night. In addition, timer cleaning also includes the case where the device is not used before 6 hours have passed since the last use, and the cleaning is performed at the scheduled time after 6 hours have passed.

[0064] The timer cleaning setting unit 8 is used to configure various settings related to the timer cleaning timing. Once the timer cleaning timing is set, the toilet cleaning unit 13 starts cleaning when the timer timing is reached or when a predetermined time has elapsed. This cleaning instruction based on the timer setting is also included as a cleaning instruction by the cleaning instruction unit.

[0065] The toilet system 1 controls the aforementioned controlled objects (such as the water supply valve 16 of the toilet flushing unit 13, the toilet lid driver 22, and the toilet seat driver 26). It also includes a control unit 5 that receives output signals from the flushing operation unit 29, the toilet lid opening / closing detector 21, the toilet seat opening / closing detector 25, and the seat occupancy detector 28a. This control unit 5 is comprised of a processor such as a CPU or MPU, as well as various programs. The toilet system 1 also includes a timer unit 6 that counts time for operations such as flushing, and a power supply unit (not shown).

[0066] The toilet device 1 also includes a notification unit 7, such as a speaker, which notifies the user of abnormalities or conditions, or provides guidance, by voice or synthesized sound. Furthermore, the notification unit 7 may include a display such as an LED, in place of or in addition to the voice output.

[0067] Next, based on Figure 3 and Figure 4 The basic operation of the toilet apparatus 1 according to the first embodiment will be described with reference to the flowcharts of FIG. The operation shown in these flowcharts is performed by the control unit 5 when a flush instruction is issued by the flush instruction means.

[0068] When a cleaning instruction is issued by the cleaning instruction unit, the toilet device 1 allows the toilet lid 20 to be closed by the toilet lid driving unit 22 if the toilet lid 20 is in the opening process, and then performs a cleaning operation by the toilet cleaning unit 13 after the toilet lid 20 is closed.

[0069] There are many forms of basic movements.

[0070] exist Figure 3 In the illustrated embodiment, when a cleaning instruction is issued based on the timer setting, the control unit 5 prohibits the above-mentioned sequential operations when the toilet lid 20 is open, and causes the toilet cleaning unit 13 to clean the toilet bowl 12 regardless of the open or closed state of the toilet lid 20.

[0071] exist Figure 4 In the illustrated embodiment, when a cleaning instruction based on the timer setting is issued, the control unit 5 prohibits the above-described sequential operations with the toilet lid 20 open, cancels the cleaning instruction, and changes the timer setting.

[0072] By executing any of the above operations, even when cleaning is performed based on the timer setting at the user's usage timing, the user's use is hardly hindered and troubles are unlikely to occur.

[0073] In the following description of the operation, the detection of the open / closed state of the toilet lid 20 and the open / closed state of the toilet seat 24 are performed by the respective detection units, but the description of the operation of these detection units is omitted. Furthermore, the opening / closing operation of the toilet lid 20 and the opening / closing operation of the toilet seat 24 are performed by the respective drive units, but the description of the operation of these drive units is omitted.

[0074] First, according to the flowchart shown in steps S100 to S111, Figure 3 In addition, in the following description, Figure 3 、 Figure 4 The part described as "step Sxxx" is simply represented by the reference numeral "Sxxx". Figure 5 、 Figure 6 Flowchart and corresponding to the third embodiment Figure 7 、 Figure 8 The same is true for the flowchart.

[0075] When a cleaning instruction is received from the cleaning instruction unit, the notification unit 7 first notifies the user of the cleaning instruction, such as by an electronic beep (S100, S101). It then determines whether the cleaning instruction is based on a timer setting. If it is not a timer cleaning instruction, the open / closed state of the toilet lid 20 is determined. If it is closed, the toilet bowl 12 is immediately cleaned (N in S102, N in S103, S109). Furthermore, the toilet bowl 12 is also cleaned while the user is seated (Y in S104, S109).

[0076] Although Figure 3 Although not shown, the toilet lid 20 may be opened after cleaning is completed, and after a certain period of time has passed since the toilet lid 20 was opened, the toilet lid 20 in the opened state may be closed and placed in a standby state (the toilet lid 20 is closed).

[0077] The opening action of the toilet lid 20 after cleaning is an action performed for the user to check the residual waste in the toilet bowl 12 after cleaning. That is, the user does not need to manually open the toilet lid 20 to check the inside of the toilet bowl 12 after cleaning.

[0078] In addition, also can replace the delay of above-mentioned certain hour, no longer detect people's timing return standby state by the human sensor.Certainly, because the user can make toilet lid 20 close action by toilet lid operating part 23, therefore also can not return standby state automatically.

[0079] If the toilet seat 24 is closed while the user is not seated, then if the toilet seat 24 (not currently seated) is opened again, the toilet seat 24 is closed. After the toilet seat 24 is closed, the toilet lid 20 is closed (S104, No, S105-S107). Furthermore, if the toilet lid 20 is closed, a different electronic "beep" sound, such as a different sound from that used during the flushing instruction, is used to notify the user that the toilet lid 20 is closed, and the toilet bowl 12 is flushed (S108, S109). Alternatively, the user may be informed that the toilet lid 20 is closed, rather than being informed that the toilet lid 20 is closed. In this case, the user is informed even when the toilet lid 20 is closed (S103, No) after the flushing instruction.

[0080] Thus, the above-described operations are executed in response to a cleaning instruction from the cleaning operation unit 29 or an automatic cleaning instruction based on detection of a change in state from seating to leaving the seat. Specifically, the toilet apparatus 1 assumes that the lid 20 is being cleaned while it is closed. When a cleaning instruction is issued by the cleaning instruction unit, if the lid 20 is in the process of being opened, the toilet apparatus 1 executes a sequential operation in which the lid 20 is closed, followed by a cleaning operation by the toilet cleaning unit 13 after the lid 20 is closed. Of course, if the toilet seat 24 is in the process of being opened, the toilet seat 24 is closed before the lid 20 is closed.

[0081] On the other hand, when the cleaning instruction is based on the timer setting, the above-mentioned sequential operation is prohibited. That is, regardless of the open or closed state of the toilet lid 20, the timer cleaning is notified by an electronic sound such as "beep, beep, beep" and the toilet bowl 12 is cleaned instead of the sequential operation (Y in S102, S110, S111).

[0082] Thus, since the toilet seat 24 and lid 20 are not closed during the timer flushing operation, the user's use can be prevented from being hindered by the closing of the toilet seat 24 and lid 20. For example, even if a man urinates while standing and the timer flushing operation coincides, the toilet seat 24 and lid 20 remain stationary while only the toilet bowl 12 is flushed, allowing the user to urinate without any hassle. This prevents urine from scattering onto the toilet seat 24, lid 20, or the floor.

[0083] Next, according to the flow chart (S200~S215), Figure 4 action.

[0084] When a cleaning instruction is received from the cleaning instruction unit, it is first determined whether the cleaning instruction is an instruction based on the timer setting. If it is not timer cleaning, the electronic sound "beep" is used to notify that the cleaning instruction has been received (N of S201, S202).

[0085] Then the open / closed state of the toilet lid 20 is judged. If it is closed, the cleaning of the toilet bowl 12 is immediately performed (N of S203, S209). In addition, when the user is seated, the cleaning of the toilet bowl 12 is also performed (Y of S204, S209).

[0086] Although Figure 4 Although not shown in the figure, the toilet lid 20 can be opened after cleaning is completed, and after a certain time has passed since the toilet lid 20 was opened, the toilet lid 20 in the opened state is closed and becomes a standby state (the toilet lid 20 is closed).

[0087] If the toilet seat 24 is closed while the user is not seated, then if the toilet seat 24 (not currently seated) is opened again, the toilet seat 24 is closed, and after the toilet seat 24 is closed, the toilet lid 20 is closed (S204, No, S205-S207). Furthermore, if the toilet lid 20 is closed, an electronic "beep" sound, different from that used during the flushing instruction, is used to notify the user that the toilet lid 20 is closed, and the toilet bowl 12 is flushed (S208, S209). Alternatively, the user may be informed that the toilet lid 20 is closed, but only that the flushing is being performed. In this case, the user is notified when the toilet lid 20 is closed (S203, No) after the flushing instruction.

[0088] Thus, the above-described operations are executed in response to a cleaning instruction from the cleaning operation unit 29 or an automatic cleaning instruction based on detection of a change in state from seating to leaving the seat. Specifically, the toilet apparatus 1 assumes that the lid 20 is being cleaned while it is closed. When a cleaning instruction is issued by the cleaning instruction unit, if the lid 20 is in the process of being opened, the toilet apparatus 1 executes a sequential operation in which the lid 20 is closed, followed by a cleaning operation by the toilet cleaning unit 13 after the lid 20 is closed. Of course, if the toilet seat 24 is in the process of being opened, the toilet seat 24 is closed before the lid 20 is closed.

[0089] On the other hand, if the cleaning instruction is based on the timer setting and the toilet lid 20 is in the open state, the above-mentioned sequential actions are prohibited. That is, the timer cleaning is canceled and the cleaning time is changed to, for example, 2 or 30 minutes later (Y in S201, Y in S210, S211, S212). Then, the electronic sound "beep, beep" is used to inform the user that the cleaning instruction has been canceled and the cleaning has been postponed (S213). In addition, Figure 4 In the action flow, canceling the timer cleaning itself is just not changing the cleaning logic, and is not a special process for canceling the cleaning, so canceling the cleaning is represented by a dotted line (S211).

[0090] If the lid 20 is closed, the timer cleaning is notified by an electronic sound such as "beep, beep, beep," and the cleaning operation of the toilet bowl 12 is performed (N in S210, S214, S215). In this case, since the lid 20 is closed when the cleaning instruction is issued, the sequential operation is naturally not performed.

[0091] Thus, since the timer flushing is canceled if the toilet lid 20 is in the process of being opened, it is possible to prevent the user from being hindered by the closing action of the toilet lid 20. For example, even if the timing of a man urinating in a standing position coincides with the timer flushing, the toilet bowl 12 is not flushed, and the user can urinate normally.

[0092] In addition, if only the overlap of a man's urination in a standing position and the timer cleaning is considered, the cancellation of the timer cleaning is not only based on the condition that the lid 20 is in the process of opening, but also based on the condition that both the lid 20 and the toilet seat 24 are in the process of opening.

[0093] Furthermore, the toilet device 1 is configured to automatically close itself when the toilet seat 24, which has not been detected as occupied, is closed and the toilet lid 20 has been open for 20 minutes. Therefore, even if the timer flush is postponed while the toilet lid 20 is still open, the probability that the lid 20 will be closed at the time of the postponement is high, making it easier for the timer flush to be executed at the postponed time.

[0094] In addition, if the toilet lid 20 is closed in the non-sitting state for 20 minutes, the time for closing the toilet lid 20 becomes longer. Figure 3 In the case of standing urination, the possibility of closing the toilet lid 20 is high, and the timer cleaning when the toilet lid 20 is in the process of opening can be reduced.

[0095] Next, based on Figure 5 and Figure 6 The basic operation of the toilet apparatus 1 according to the second embodiment will be described with reference to the flowcharts of FIG. The operation shown in these flowcharts is performed by the control unit 5 when a flush instruction is issued by the flush instruction means.

[0096] In this toilet device 1, the flushing instruction from the flushing instruction unit includes a flushing instruction set by a timer. The control unit 5 is configured to prohibit sequential operation if the obstacle detection unit 28 detects a person or object at the timing of the flushing instruction set by the timer.

[0097] According to the flowchart shown in steps S300 to S313 (refer to Figure 5 ) and steps S400 to S408 (refer to Figure 6 )right Figure 5and Figure 6 The following describes the action.

[0098] When a cleaning instruction based on the cleaning instruction unit is received, it is first determined whether the cleaning instruction is an instruction based on timer cleaning (S300, S301). If it is not timer cleaning, the notification unit 7 notifies, for example, through an electronic sound "beep", that it is a cleaning instruction issued by the cleaning operation unit 29 other than timer cleaning (N of S301, S302). In addition, the open / closed state of the toilet lid 20 is determined. If the toilet lid 20 is in the closed state, the toilet bowl 12 is immediately cleaned (N of S303, S309). In addition, when the toilet lid 20 is in the open state and the toilet seat 24 is seated, the toilet bowl 12 is also cleaned (Y of S303, Y of S304, S309).

[0099] Although Figure 5 Although not shown, the toilet lid 20 may be opened after cleaning is completed, and after a certain period of time has passed since the toilet lid 20 was opened, the toilet lid 20 in the opened state may be closed and placed in a standby state (the toilet lid 20 is closed).

[0100] The opening action of the toilet lid 20 after cleaning is an action performed for the user to check the residual waste in the toilet bowl 12 after cleaning. That is, the user does not need to manually open the toilet lid 20 to check the inside of the toilet bowl 12 after cleaning.

[0101] In addition, also can replace the delay of above-mentioned certain hour, no longer detect the people's timing return standby state by human body detecting portion 28b.Certainly, because the user can make toilet lid 20 close action by toilet lid operating portion 23, therefore also can not automatically return standby state.

[0102] On the other hand, if the toilet lid 20 is open and the toilet seat 24 is not occupied, the open / closed state of the toilet seat 24 is determined (Y in S303, N in S304, S305). If the toilet seat 24 is closed, the toilet seat 24 is closed if it is opened again. After the toilet seat 24 is closed, the toilet lid 20 is closed (S305-S307).

[0103] If the toilet lid 20 is closed, the toilet lid 20 is notified of this by an electronic "beep" sound, different from that used during the cleaning instruction, and the toilet bowl 12 is cleaned (S307-S309). This notification can be made just before the toilet lid 20 is completely closed, or when the toilet lid 20 is completely closed. Alternatively, a notification to cleanse can be made. If the cleaning instruction is given, the notification is also made when the toilet lid 20 is closed (N in S303) after the cleaning instruction.

[0104] Thus, the above-described operations are executed in response to a cleaning instruction from the cleaning operation unit 29 or an automatic cleaning instruction based on detection of a change in state from seating to leaving the seat. Specifically, the toilet apparatus 1 is designed to clean the lid 20 while it is closed. However, when a cleaning instruction is issued by the cleaning instruction unit, if the lid 20 is in the process of opening, a sequential operation is executed, in which the lid 20 is closed, followed by a cleaning operation by the toilet cleaning unit 13. Of course, if the toilet seat 24 is in the process of opening, the toilet seat 24 is closed before the lid 20 is closed.

[0105] On the other hand, if the cleaning instruction is based on a timer setting, the open / closed state of the toilet lid 20 is determined. If it is closed, an electronic sound such as "beep, beep, beep" is used to notify the user of the timer cleaning (S300, Y in S301, Y in S310, S311). The toilet bowl 12 is then cleaned (S312). Alternatively, in this case, the open / closed state of the toilet lid 20 may be determined instead of the open / closed state.

[0106] In addition, when the toilet lid 20 is in the open state (not in the closed state), the toilet lid open timer cleaning process (N in S310, S313) is executed. Figure 6 The details are described in S400 to S408 of the flowchart.

[0107] The timer flushing process for when the toilet lid is open is based on the presence of a person or object near the toilet bowl 12, as determined by the obstacle detection unit 28. If no person or object is detected, the timer flushing is executed, and if a person or object is detected, the timer flushing is canceled. In this example, the timer flushing is canceled if the detection of a person or object continues for a certain period of time.

[0108] Specifically, first, start counting for measuring a certain time (S400, S401). If a person or object is continuously detected before the certain time, do not perform timer cleaning (N of S402, Y of S403, Y of S402, S408). That is, cancel the timer cleaning.

[0109] On the other hand, when there is no person or object that becomes an obstacle from the beginning, or when the state changes from a state where a person or object is detected to a state where no person or object is detected during a certain period of time, it is judged that the timer cleaning state can be performed (N of S402, N of S403).

[0110] Next, the start of the timer flush is notified, and the lid 20 is closed. If the lid 20 is closed, this notification is made, and flushing is performed (N in S403, S404-S407). In this case, the toilet flushing sequence is also executed, following the lid 20 closing sequence. Furthermore, if the toilet seat 24 is open, the lid 20 is closed before the lid 20 is closed.

[0111] Thus, even if the toilet lid 20 is open at the time of the timer purge indication, if there is no obstacle preventing the lid 20 from closing, or if the obstacle disappears within a certain period of time, the timer purge will be executed. For example, the timer purge can be executed if the toilet lid 20 is left open or if there is a temporary obstruction caused by a person or object. In this case, since the toilet lid 20 is closed first in a sequential operation, the dispersion of droplets containing pollutants in the toilet bowl 12 is suppressed.

[0112] Of course, if a person or object is detected for a certain period of time, the timer cleaning is canceled as described above and the closing action of the toilet lid 20 is not executed, thereby preventing a man from urinating while standing and being hindered by the toilet lid 20. In addition, for example, it is possible to avoid the timer cleaning action of closing the toilet lid 20 and performing the cleaning when the user is checking his or her feces with the toilet lid 20 open.

[0113] As mentioned above, Figure 6 If a person or object is continuously detected during the period from when a cleaning instruction is issued based on the timer until a certain time has passed, the sequential action is continuously prohibited. On the other hand, if a person or object is detected during the period from when a cleaning instruction is issued based on the timer until a certain time has passed, the sequential action is executed if the state changes from when a person or object is detected to when no person or object is detected.

[0114] In this manner, when a person or object is detected for a certain period of time, timer cleaning (sequential operation) is prohibited. However, if a person or object is detected at the timing of the cleaning instruction, the operation may be immediately prohibited.

[0115] In addition, Figure 6 In the operation, if the detection of a person or an object by the obstacle detection unit 28 continues for a certain time, the timer cleaning is canceled, but the timer cleaning may be performed at a predetermined time after the cancellation.

[0116] The aforementioned predetermined time is preferably the time it takes for a man to urinate or to detect feces in the toilet bowl 12, but it can be substantially longer than this, for example, approximately 5 to 10 minutes. In the case of such long-term monitoring, if no person or object is detected within this time, cleaning can be canceled and an abnormality notification can be issued. This can also notify those outside the toilet that a person is immobilized within the toilet and that cleaning tools are placed in the toilet bowl 12.

[0117] In addition, when it is determined that timer cleaning is possible ( Figure 6 (After N in S403 of step 404), it is also possible to check whether a purge has just been performed, and if it is detected that a purge has just been performed, the timer purge may not be performed. For example, if a man urinates while standing and completes his urination and purge within the specified time, the timer purge may not be performed because the purge and the timer purge are continuous. Alternatively, the presence of water flow or software determination may be used to determine whether a purge has just been performed.

[0118] In addition, in this embodiment, although the seat detection unit 28a and the human body detection unit 28b are both the obstruction detection means 28 for closing the toilet lid 20, it is also possible to determine that the opening of the toilet bowl 12 is blocked by a person when sitting, and to perform cleaning without closing the toilet lid 20. That is, in the case of a cleaning instruction based on an operation other than timer cleaning ( Figure 5 Similarly to the action on the N side of S304, when the user is sitting on the toilet seat 24, the timer cleaning can be performed without operating the toilet cover 20 when the timer cleaning timing is reached.

[0119] Next, based on Figure 7 and Figure 8 The basic operation of the toilet apparatus 1 according to the third embodiment will be described with reference to the flowcharts of FIG. The operation shown in these flowcharts is performed by the control unit 5 when a flush instruction is issued by the flush instruction means.

[0120] In the case of a flushing instruction based on a timer setting, the toilet apparatus 1 causes the notification unit 7 or the toilet seat-side notification unit 37 to notify that the sequence operation based on the timer setting is to be executed before the sequence operation is executed.

[0121] First, according to the flowchart shown in steps S500 to S516, Figure 7 action.

[0122] When a cleaning instruction is received from the cleaning instruction unit, it is first determined whether the cleaning instruction is an instruction set based on a timer (timer cleaning). If it is not a timer cleaning, the notification unit 7 notifies the user of the receipt of the cleaning instruction (S500, N in S501, S502). The notification by the notification unit 7 is performed, for example, by an electronic sound "beep". Thereafter, the open / closed state of the toilet lid 20 is determined. If it is closed, the toilet bowl 12 is cleaned (N in S503, S509). Furthermore, even if the toilet lid 20 is open, if the toilet seat 24 is occupied, the toilet bowl 12 is cleaned (Y in S503, Y in S504, S509).

[0123] Although Figure 7 Although not shown, the toilet lid 20 may be opened after cleaning is completed, and after a certain period of time has passed since the toilet lid 20 was opened, the toilet lid 20 in the opened state may be closed and placed in a standby state (the toilet lid 20 is closed).

[0124] The opening action of the toilet lid 20 after cleaning is an action performed for the user to check the residual waste in the toilet bowl 12 after cleaning. That is, the user does not need to manually open the toilet lid 20 to check the inside of the toilet bowl 12 after cleaning.

[0125] In addition, also can replace the delay of above-mentioned certain hour, no longer detect people's timing return standby state by the human sensor.Certainly, because the user can make toilet lid 20 close action by toilet lid operating part 23, therefore also can not return standby state automatically.

[0126] If the toilet lid 20 is open and the toilet seat 24 is not in the seated position, the open / closed state of the toilet seat 24 is determined (Y in S503, N in S504, S505). If the toilet seat 24 is closed, then if it is open again, the toilet seat 24 is closed. After the toilet seat 24 is closed, the toilet lid 20 is closed (S506, S507). Furthermore, if the toilet lid 20 is closed, the notification unit 7 notifies the user of this fact through an electronic "beep" sound, which is different from the notification in S502, and then performs cleaning (S508, S509). This notification can be made when the toilet lid 20 is approximately closed, just before it is closed, or when the toilet lid 20 is completely closed. Furthermore, the notification unit 7 can also notify the user of the cleaning process. In this case, the notification unit 7 also notifies the user of the cleaning process when the toilet lid 20 is closed (N in S503) after the cleaning instruction.

[0127] Thus, the above-described operations are executed in response to a cleaning instruction from the cleaning operation unit 29 or an automatic cleaning instruction based on detection of a change in state from seating to leaving the seat. In principle, the toilet apparatus 1 cleans with the toilet lid 20 closed. However, when a cleaning instruction is issued by the cleaning instruction unit, if the toilet lid 20 is in the process of opening, the lid 20 is closed. Furthermore, after detecting that the toilet lid 20 is closed, the toilet cleaning unit 13 executes the cleaning sequence. Of course, if the toilet seat 24 is in the process of opening, the toilet seat 24 is closed before the lid 20 is closed.

[0128] On the other hand, when the cleaning instruction is based on the timer setting, the open / closed state of the toilet lid 20 is determined. If the toilet lid 20 is closed, cleaning is immediately performed (Y at S501, N at S510, S516). If the cleaning instruction is based on the timer setting and the toilet lid 20 is in the process of opening, before the above-mentioned sequential actions are performed, the notification unit 7 notifies the user of the execution of the sequential actions based on the timer setting (Y at S501, Y at S510, S511).

[0129] This notification is performed by notification unit 7, for example, through an electronic sound such as a beep. After a predetermined period of time has passed since notification unit 7 issued the notification, the open / closed state of toilet seat 24 is determined. If toilet seat 24 is closed, the toilet seat 24 is then closed. After toilet seat 24 is closed, the toilet lid 20 is closed (S512-S515). Furthermore, if the toilet lid 20 is closed, cleaning is performed (S516). The predetermined delay after notification unit 7 issued the notification can be a few seconds to approximately 10 seconds.

[0130] Thus, if the purge instruction is based on a timer setting, a predetermined delay is provided after the notification by notification unit 7. The notification by notification unit 7 allows the user to know that the timer purge is scheduled, and can easily avoid contact with the toilet lid 20 before the toilet lid 20 begins closing. Furthermore, even if a man's urination in a standing position coincides with the timer purge, notification unit 7 will notify him before the sequential action is performed. Therefore, a man urinating in a standing position can avoid urine being scattered around due to the closing toilet lid 20. Furthermore, since purge is performed after the toilet lid 20 is closed, the scattering of droplets containing pollutants around the main body 10 is suppressed.

[0131] Although Figure 7Although not shown, the cleaning instruction is based on the timer setting, and even if the toilet lid 20 is open, if the toilet seat 24 is occupied, cleaning can be performed after notification by the notification unit 7. Furthermore, even if the cleaning instruction is based on the timer setting, if the toilet seat 24 is occupied, the toilet lid 20 is considered to be closed, and cleaning can be performed without notification by the notification unit 7.

[0132] In addition, although Figure 7 Although not shown, a configuration may also be employed in which, when the toilet lid 20 is open when a purge instruction is issued based on a timer setting, the toilet lid 20 is monitored for a change to a closed state during a predetermined delay period following notification by the notification unit 7. In this case, if the toilet lid 20 is closed during the delay period, purge operation can be initiated immediately. If the toilet lid 20 is still open after the delay, the open / closed state of the toilet seat 24 is determined. If the toilet seat 24 is closed, the toilet lid 20 is closed after the toilet seat 24 is opened again. Furthermore, if the toilet lid 20 is closed, purge operation is initiated.

[0133] Next, the flowchart shown in steps S600 to S615 is described. Figure 8 action.

[0134] When a cleaning instruction is received from the cleaning instruction unit, first, it is determined whether the cleaning instruction is an instruction based on the timer setting (timer cleaning). If it is not a timer cleaning, the notification unit 7 notifies (S600, N in S601, S602). The notification by the notification unit 7 is a sequential notification when performing sequential actions. The sequential notification is performed, for example, by an electronic sound "beep". In addition, the open / closed state of the toilet lid 20 is determined. If it is closed, the toilet bowl 12 is cleaned (N in S603, S609). In addition, even if the toilet lid 20 is in the open state, if the toilet seat 24 is seated, the toilet bowl 12 is cleaned (Y in S603, Y in S604, S609).

[0135] Although Figure 8 Although not shown, the toilet lid 20 may be opened after cleaning is completed, and after a certain period of time has passed since the toilet lid 20 was opened, the toilet lid 20 in the opened state may be closed and placed in a standby state (the toilet lid 20 is closed).

[0136] The opening action of the toilet lid 20 after cleaning is an action performed for the user to check the residual waste in the toilet bowl 12 after cleaning. That is, the user does not need to manually open the toilet lid 20 to check the inside of the toilet bowl 12 after cleaning.

[0137] In addition, also can replace the delay of above-mentioned certain hour, no longer detect people's timing return standby state by the human sensor.Certainly, because the user can make toilet lid 20 close action by toilet lid operating part 23, therefore also can not return standby state automatically.

[0138] If the toilet lid 20 is in the open state and the toilet seat 24 is not in the seated state, the open / closed state of the toilet seat 24 is determined (Y in S603, N in S604, S605). If the toilet seat 24 is in the closed state, the toilet seat 24 is closed if it is opened again. After the toilet seat 24 is closed, the toilet lid 20 is closed (S606, S607).

[0139] If the toilet lid 20 is in the closed state, the sequential operation is executed, and the notification unit 7 notifies the toilet lid 20 of the closed state through an electronic sound such as a beep (sequential notification), and then performs cleaning (S608, S609). In addition, this notification can be performed when the toilet lid 20 is about to be closed, or when the toilet lid 20 is completely closed. Alternatively, the cleaning execution can be notified (sequential notification). In this case, the cleaning instruction is also given when the toilet lid 20 is closed (N in S603).

[0140] Thus, the above-described operations are executed upon a cleaning instruction from the cleaning operation unit 29 or an automatic cleaning instruction based on detection of a change in state from seating to leaving the seat. Specifically, the toilet apparatus 1 assumes that the lid 20 is closed for cleaning. When a cleaning instruction is issued by the cleaning instruction unit, the lid 20 closes if it is in the process of opening. Furthermore, after detecting that the lid 20 is closed, the toilet cleaning unit 13 executes the cleaning sequence. Of course, if the toilet seat 24 is in the process of opening, the seat 24 closes before the lid 20 closes.

[0141] On the other hand, when the cleaning instruction is based on the timer setting, the open / closed state of the toilet lid 20 is determined. If the toilet lid 20 is closed, cleaning is immediately performed (Y at S601, N at S610, S615). If the cleaning instruction is based on the timer setting and the toilet lid 20 is in the process of opening, before the sequential operation is performed, the notification unit 7 notifies (alerts) that the sequential operation based on the timer setting will be performed (Y at S601, Y at S610, S611).

[0142] This alarm is issued by notification unit 7 using an electronic sound such as "beep, beep, beep" that varies in tone output pattern, timing, and sequence. After the alarm is issued by notification unit 7, the open / closed state of toilet seat 24 is determined. If toilet seat 24 is closed, the system then closes it. If it is open again, the system then closes the toilet lid 20 (S612-S614). Furthermore, if the toilet lid 20 is closed, cleaning is performed (S615).

[0143] Thus, if the cleaning instruction is based on the timer setting, a notification (alarm) different from the sequential notification is executed in the notification unit 7. By using the alarm different from the sequential notification, the user is notified in advance of the start of the closing action of the toilet lid 20 based on the timer cleaning, and can therefore easily avoid contact with the toilet lid 20.

[0144] Furthermore, even if a man's urination in a standing position coincides with the timer purge, notification unit 7 issues an alarm before the sequence is executed. This prevents urine from scattering around the toilet lid 20 as the lid closes. Furthermore, since purge is performed after the lid 20 is closed, droplets containing contaminants are prevented from scattering around the toilet body 10.

[0145] In addition, it is preferable that the notification (alarm) different from the sequential notification by the notification unit 7 is performed between several seconds and about 10 seconds, instead of delaying the closing action of the toilet lid 20. If the alarm time is several seconds to about 10 seconds, the user can easily avoid contact with the toilet lid 20 in advance.

[0146] Although Figure 8 Although not shown, even if the cleaning instruction is based on a timer setting and the toilet lid 20 is in the open state, if the toilet seat 24 is occupied, cleaning is performed after the notification (alarm) by the notification unit 7. Alternatively, even if the cleaning instruction is based on a timer setting, if the toilet seat 24 is occupied, the toilet lid 20 is considered to be in the closed state, and cleaning is performed without the notification (alarm) by the notification unit 7.

[0147] In addition, although Figure 8Although not shown, if the toilet lid 20 is in the open state when a cleaning instruction is issued based on a timer setting, a delay of a predetermined time period may be set after the alarm issued by the notification unit 7. Alternatively, an action structure may be configured to monitor the change of the toilet lid 20 to the closed state during this delay. In this case, if the toilet lid 20 becomes closed during the delay, cleaning can be started immediately. If the toilet lid 20 is still open after the delay, the open / closed state of the toilet seat 24 is determined. If the toilet seat 24 is closed, then if the toilet seat 24 is open again, the toilet seat 24 is closed after the toilet seat 24 is closed. Then, if the toilet lid 20 is closed, cleaning is performed.

[0148] In this action form, since there is a delay after the alarm, the user can easily avoid contact with the toilet lid 20. In addition, in this action form, since there is a delay after the alarm, the alarm time may be approximately 10 seconds instead of a few seconds of delay.

[0149] in addition, Figure 8 The alarm shown is an electronic sound in a different form from the sequential notification, but is not limited to this. The alarm may also be a voice synthesis such as "Start timer cleaning." In addition, the alarm may not be a sound output but a light output, for example, it may be an alarm such as the lighting or flashing of an LED, or a message display based on a display. In addition, the alarm may be a combination of the voice synthesis or light output described above, in addition to an electronic sound in the same or different form as the sequential notification. In addition, the alarm may also be an alarm that changes the pitch and volume of the sound without changing the output mode or output time of the sound from the electronic sound "beep" or "beep" of the sequential notification. In addition, these alarms are sufficient as long as the people in the toilet space can know them, and do not need to be transmitted to people outside the toilet space.

[0150] in addition, Figure 7 、 Figure 8 The example of the operation is merely one example, and different operation modes are possible. For example, the cleaning instruction may be based on a timer setting and the toilet lid 20 may be in the open state. After the toilet lid 20 is closed, the notification unit 7 may issue a notification or alarm after detecting that the toilet lid 20 is closed. Furthermore, in the above description, when it is determined that both the toilet lid 20 and the toilet seat 24 are open, the toilet seat 24 is closed first, and then the toilet lid 20 is closed. However, the toilet lid 20 may also be closed in conjunction with the closing of the toilet seat 24.

[0151] The toilet device 1 is not limited to the above device, and can also be other action forms. In addition, it can be a device in which the toilet seat 24 and the toilet cover 20 can be replaced as a whole. In particular, Figure 9 The toilet apparatus 3 shown is later installed (or replaced) with the toilet seat apparatus 30. As the toilet seat apparatus 30 and the toilet apparatus 3, there can be mentioned apparatuses corresponding to the respective operations of the toilet apparatuses 1 of the first to third embodiments described above.

[0152] based on Figure 9 (a) and Figure 9 (b) of the present invention, the basic structure of the toilet device 3 of another embodiment of the present invention will be described. Figure 9 (b) shows a movable return bend 17A, but it can also be applied to a toilet body having a siphon return bend 17 (see Figure 2 (a)) structure or other structure.

[0153] Specifically, the toilet apparatus 3 includes a toilet bowl 12, a toilet washing unit 13 that supplies washing water to the toilet bowl 12 and washes the inside of the toilet bowl 12, a toilet seat device 30, and a washing operation unit 29 that outputs a washing instruction to the toilet washing unit 13. The toilet apparatus 3 also includes a control unit 5, a timer unit 6, a notification unit 7, and a timer washing setting unit 8.

[0154] The toilet seat device 30 and the toilet body of the toilet device 3 (excluding the toilet seat device 30) are detachable separate structures. The toilet seat device 30 includes: a toilet lid 40, a toilet lid opening and closing detection unit 41, a toilet lid driving unit 42, a toilet lid operating unit 43, a toilet seat 44, a toilet seat opening and closing detection unit 45, a toilet seat driving unit 46, a toilet seat operating unit 47, an obstacle detection unit 48, a toilet bowl cleaning operating unit 49, a toilet seat side control unit 35, and a notification unit 37. As an obstacle detection unit 48, Figure 1 The obstacle detection unit of the toilet seat 30 is similarly composed of a seat detection unit 48a and a human body detection unit 48b. In addition, signals can be sent and received between the toilet seat device 30 and the toilet body.

[0155] In addition, since the structure of the toilet device 3 (toilet body) other than the toilet seat device 30 is the same as Figure 1 The structure of the toilet seat device 30 is substantially the same as that of the toilet seat device 30, so detailed description is omitted. In addition, the toilet lid 40, toilet lid opening and closing detection unit 41, toilet lid driving unit 42, toilet lid operation unit 43, toilet seat 44, toilet seat opening and closing detection unit 45, toilet seat driving unit 46, toilet seat operation unit 47, sitting detection unit 48a, and human body detection unit 48b are also the same as those of the toilet seat device 30. Figure 1 The structure is roughly the same.

[0156] Figure 9The toilet seat device 30 is configured to output a flushing instruction for the toilet bowl 12 to the toilet bowl cleaning unit 13 from the toilet seat device 30. Specifically, when a flushing instruction is issued from the toilet bowl cleaning operation unit 49, the toilet seat control unit 35 receives the instruction, notifies the toilet body of the flushing instruction, and controls the toilet bowl 12 through the toilet body control unit 5, thereby enabling flushing of the toilet bowl 12. Alternatively, a configuration in which the toilet seat control unit 35 directly controls the toilet bowl cleaning unit 13 is also possible.

[0157] In addition, if Figure 9 As shown, the toilet device 3 is a structure including not only the toilet bowl washing operation part 49 on the toilet seat device 30 side, but also the washing operation part 29 on the main body side. Figure 9 The structure is such that both the washing operation unit 29 and the toilet bowl washing operation unit 49 can issue a washing instruction. Alternatively, a structure is also possible in which the washing operation unit 29 is not provided on the main body side, and the washing instruction is issued only through the toilet bowl washing operation unit 49. In addition, the toilet bowl washing operation unit 49 also preferably has a washing button for defecation and a washing button for urine.

[0158] The operation of the toilet bowl cleaning operation unit 49 functions as a toilet bowl cleaning instruction unit, and the change in state from being seated to being unseated detected by the seating detection unit 48a also functions as a toilet bowl cleaning instruction unit. That is, when the toilet seat 44 is raised while the user is seated, automatic cleaning is performed instead of operating the cleaning button.

[0159] In addition, in the cleaning instructions of the toilet body, Figure 1 The toilet apparatus 1 shown also includes a flushing instruction based on a timer setting, and the toilet seat apparatus 30 receives flushing instructions based on a timer setting in addition to flushing instructions from the toilet bowl flushing instruction unit or the flushing operation portion 29 of the toilet body.

[0160] As described above, the toilet seat device 30 includes a toilet seat 44, a toilet lid 40, a toilet lid opening / closing detection unit 41 that detects the opening and closing of the toilet lid 40, and a toilet lid driving unit 42 that opens and closes the toilet lid 40. Furthermore, the toilet seat device 30 is a device attached to the toilet bowl body and includes a toilet bowl cleaning instruction unit that receives cleaning instructions for the toilet bowl body and a toilet seat-side control unit 35. When a cleaning instruction is issued by the toilet bowl cleaning instruction unit or the toilet bowl body, the toilet lid 20 is allowed to start closing by the toilet lid driving unit 22 while the toilet lid 20 is in the process of opening, and then a cleaning instruction is output to the toilet bowl body after the closed state of the toilet lid 20 is detected.

[0161] If the toilet body receives the cleaning instruction, the toilet bowl 12 starts to be cleaned on the toilet body. That is, the sequential processing of the toilet seat device 30 executes the sequential actions of the toilet device 3 (cooperation between the toilet seat device 30 and the toilet body) (with Figure 1The sequential actions of the toilet device 1 are equivalent to the actions).

[0162] Hereinafter, the toilet apparatus 3 (toilet seat apparatus 30 ) corresponding to the operation of the toilet apparatus 1 of the first to third embodiments will be described.

[0163] As the toilet device 3 corresponding to the first embodiment, when there is a cleaning instruction, Figure 1 Similarly, the toilet device 1 can be Figure 3 、 Figure 4 In short, when there is a cleaning instruction from the toilet bowl cleaning instruction unit (toilet bowl cleaning operation unit 49) or the toilet body, the toilet bowl 12 is cleaned in principle with the toilet lid 40 closed. However, as an exception, when a cleaning instruction based on the timer setting is received from the toilet body, the cleaning unit 13 performs the cleaning. Figure 3 、 Figure 4 action.

[0164] When there is a cleaning instruction based on the timer setting, the toilet seat side control unit 35 prohibits the above-mentioned sequence processing in the open state of the toilet lid 20, and outputs a cleaning instruction to the toilet body regardless of the open or closed state of the toilet lid 20. Figure 3 The actions shown correspond.

[0165] In addition, when there is a cleaning instruction based on the timer setting, the toilet seat side control unit 35 may prohibit the above-mentioned sequential processing in the open state of the toilet lid 20 and output a predetermined cleaning cancellation instruction to the toilet body. This action corresponds to Figure 4 In addition, in the toilet body, according to the cancellation instruction, the setting change of the timer cleaning delay can be performed.

[0166] As the toilet device 3 corresponding to the second embodiment, when there is a cleaning instruction, Figure 1 Similarly, the toilet device 1 can be Figure 5 and Figure 6 In short, when there is a cleaning instruction from the toilet bowl cleaning instruction unit (toilet bowl cleaning operation unit 49) or the toilet body, the toilet bowl 12 is cleaned in principle with the toilet lid 40 closed. However, as an exception, when a cleaning instruction based on the timer setting is received from the toilet body, the cleaning unit 13 is executed. Figure 5 and Figure 6 action.

[0167] The toilet seat side control unit 35 is configured to prohibit the sequential processing when a person or object is detected by the obstacle detection unit 48 at the timing of the cleaning instruction set by the timer. Figure 4 Similarly, the detection of a person or object is continued for a certain period of time as a condition.

[0168] As the toilet device 3 corresponding to the third embodiment, when there is a cleaning instruction, Figure 1 Similarly, the toilet device 1 can be Figure 7 、 Figure 8 In short, when there is a cleaning instruction from the toilet bowl cleaning instruction unit (toilet bowl cleaning operation unit 49) or the toilet body, the toilet bowl cleaning unit 13 performs cleaning of the toilet bowl 12 after detecting the closed state of the toilet lid 40. Moreover, when a cleaning instruction based on the timer setting is received from the toilet body, the cleaning unit 13 performs the cleaning of the toilet bowl 12. Figure 7 、 Figure 8 action.

[0169] The flushing instructions issued by the toilet bowl flushing instruction unit or the toilet body include flushing instructions set based on a timer. When a flushing instruction set based on a timer is issued, the toilet seat-side control unit 35 causes the toilet seat-side notification unit 37 or the toilet body notification unit 7 to notify the user of the execution of the sequential processing set based on the timer before the sequential processing is executed while the toilet lid 40 is in the process of being opened.

[0170] In addition, when there is a cleaning instruction based on the timer setting, the toilet lid 40 may be closed by the toilet lid driving unit 42 after a predetermined time has passed after the toilet seat side notification unit 37 or the toilet body notification unit 7 has notified the toilet lid 40 while it is in the process of opening. Figure 7 The actions shown correspond.

[0171] In addition, the toilet seat side notification unit 37 or the toilet body notification unit 7 can also perform sequential notification when executing sequential processing. The notification before the sequential processing when there is a cleaning instruction based on the timer setting is a notification in a different form from the sequential notification. That is, this action is different from Figure 8 The actions shown correspond.

[0172] Regarding the notification of the cleaning instruction timing in the above-mentioned operation of the toilet device 3, the notification of the closing timing of the toilet lid 40, the notification of the sequential operation based on the timer cleaning, etc., it can be performed by either the notification unit 37 of the toilet seat device 30 or the notification unit 7 of the toilet body.

[0173] In addition, notifications (alarms) different from the sequential notifications during sequential processing or the sequential notifications based on timer cleaning may be made by either the toilet seat side notification unit 37 of the toilet seat device 30 or the notification unit 7 of the toilet body. Figure 9 Although not shown in the figure, the toilet seat device 30 may also include a timing unit. In this case, in the measurement of various times, it can be performed by the timing unit of the toilet seat device 30 or the timing unit 6 of the toilet body.

[0174] In addition, the toilet seat device 30 is not limited to Figure 9 The toilet seat device 30 may be, for example, a toilet seat device equipped with a private cleaning device, or a toilet seat operating unit (not shown) capable of performing various operations (for example, the private cleaning device) or settings.
