As the remote controller, an infrared communication remote controller is preferably used. Needless to say, the remote controller is provided with a transmitting unit (not shown), and the main body 10 is provided with a receiving unit (not shown).
　洗浄操作部２９の操作は洗浄指示手段として作用するが、さらに、着座検知部２８により検知された、着座中から離座への状態変化も洗浄指示手段として作用する。つまり、人が着座中のときに便座２４から立ち上がった際には、洗浄ボタンの操作に代えて自動洗浄がなされる。その他、タイマー設定による自動洗浄（自動洗浄機能）によるタイマーをトリガーとしたものも洗浄指示手段とされる。 The operation of the cleaning operation unit 29 acts as a cleaning instruction means, and further, the state change from sitting to leaving the seat detected by the seating detection unit 28 also acts as a cleaning instruction means. That is, when a person stands up from the toilet seat 24 while sitting, automatic cleaning is performed instead of operating the cleaning button. In addition, a timer triggered by an automatic cleaning (automatic cleaning function) by setting a timer is also used as a cleaning instruction means.
　また、大便用洗浄ボタン２９ａおよび小便用洗浄ボタン２９ｂの両方を設けずに、１つの洗浄ボタンで洗浄指示を出力する構成としてもよい。つまり、その場合のボウル１２への洗浄水の水量としては、大便用大容量、小便用小容量の区別がなく、大便用大容量の１種類のみとされる。 Further, it is also possible to output a cleaning instruction with one cleaning button without providing both the stool cleaning button 29a and the urine cleaning button 29b. That is, in that case, the amount of washing water in the bowl 12 is not distinguished between the large capacity for stool and the small capacity for urine, and is only one type of the large capacity for stool.
　便器装置１は、上記制御対象（便器洗浄部１３の給水弁１６や便蓋駆動部２２、便座駆動部２６など）を制御する一方、洗浄操作部２９や便蓋開閉検知部２１、便座開閉検知部２５、着座検知部２８、人体検知部９などの出力信号を受ける制御部５を備えている。この制御部５はＣＰＵやＭＰＵなどのプロセッサおよび種々のプログラムを含んで構成される。便器装置１はさらに、計時部（不図示）および電源部（不図示）を備えている。 The toilet device 1 controls the above-mentioned control targets (water supply valve 16 of the toilet cleaning unit 13, toilet lid drive unit 22, toilet seat drive unit 26, etc.), while the cleaning operation unit 29, toilet lid open / close detection unit 21, and toilet seat open / close detection are detected. It includes a control unit 5 that receives output signals such as a unit 25, a seating detection unit 28, and a human body detection unit 9. The control unit 5 includes a processor such as a CPU and an MPU and various programs. The toilet device 1 further includes a time measuring unit (not shown) and a power supply unit (not shown).
　また、便器装置１は、装置の異常や状態、ガイダンスを音や音声合成で報知するスピーカなどで構成された報知部７を備えている。なお報知部７としては、音出力のものに代えてあるいは加えて、ＬＥＤなどのディスプレイを備えた構成としてもよい。 Further, the toilet bowl device 1 includes a notification unit 7 composed of a speaker or the like that notifies an abnormality or state of the device or guidance by sound or voice synthesis. The notification unit 7 may be configured to include a display such as an LED in place of or in addition to the sound output unit.
　ついで、この便器装置１の基本動作について、図３～図５のフローチャートにもとづいて説明する。これらの動作はいずれも、人体検知部９により人体が検知されたときの制御部５による便蓋２０の開動作に関連した処理である。この便蓋２０の開動作は、使用者の利便性などの観点から、入室の際に自動で便蓋２０が開く動作である。 Next, the basic operation of the toilet bowl device 1 will be described with reference to the flowcharts of FIGS. 3 to 5. All of these operations are processes related to the opening operation of the toilet lid 20 by the control unit 5 when the human body is detected by the human body detection unit 9. The opening operation of the toilet lid 20 is an operation of automatically opening the toilet lid 20 when entering the room from the viewpoint of user convenience and the like.
　便器装置１は、人体が検知されたとき（入室したとき）に図３～図５のいずれかの動作が実行される動作構成となっていればよいが、いずれかの動作が実行されるように便器装置１に対する設定で変更できるようにしてあってもよい。 The toilet device 1 may have an operation configuration in which any of the operations of FIGS. 3 to 5 is executed when a human body is detected (when entering the room), but any of the operations may be executed. It may be possible to change the setting for the toilet bowl device 1.
　以下の動作説明においては、便蓋２０の開閉状態の検知や便座２４の開閉状態の検知は各検知部によるものであるが、それらの検知部の動作の説明については省略する。また、便蓋２０の開閉動作や便座２４の開閉動作は各駆動部によるものであるが、それらの駆動部の動作の説明については省略する。 In the following operation explanation, the detection of the open / closed state of the toilet lid 20 and the detection of the open / closed state of the toilet seat 24 are performed by each detection unit, but the description of the operation of those detection units will be omitted. Further, although the opening / closing operation of the toilet lid 20 and the opening / closing operation of the toilet seat 24 are performed by each drive unit, the description of the operation of those drive units will be omitted.
　まず、図３の動作について、ステップＳ１００～Ｓ１０９で示されるフローチャートに沿って説明する。なお以下の説明では、図３～図５の動作ステップについて、「ステップＳ×××」と記述するところを、符号のみの「Ｓ×××」と略記した。 First, the operation of FIG. 3 will be described with reference to the flowcharts shown in steps S100 to S109. In the following description, the operation step of FIGS. 3 to 5 described as "step SXXX" is abbreviated as "SXXX" having only a code.
　人体検知部９により人体が検知されたとき、便蓋２０の開／閉状態が判別され、開状態であれば、便蓋２０に開動作に関する処理は必要がなく、本処理を終了する（Ｓ１００、Ｓ１０１のＮ）。一方、人体が検知されたときに便蓋２０が閉状態であれば、便蓋２０の開動作が開始される（Ｓ１００、Ｓ１０１のＹ、Ｓ１０２）。その便蓋２０の開動作中（便蓋２０が開状態となるまで）に洗浄指示がない場合には、処理を終了する（Ｓ１０３のＮ、Ｓ１０４、Ｓ１０４のＹ）。つまり、その後、便蓋２０は開き、使用者が使用できる状態になる。 When the human body is detected by the human body detection unit 9, the open / closed state of the toilet lid 20 is determined, and if the toilet lid 20 is in the open state, the toilet lid 20 does not need to perform the processing related to the opening operation, and this processing is terminated (S100). , S101 N). On the other hand, if the toilet lid 20 is in the closed state when the human body is detected, the opening operation of the toilet lid 20 is started (Y, S102 of S100, S101). If there is no cleaning instruction during the opening operation of the toilet lid 20 (until the toilet lid 20 is in the open state), the process is terminated (N of S103, Y of S104, S104). That is, after that, the toilet lid 20 is opened and is ready for use by the user.
　便蓋２０が開状態となるまでに洗浄指示を受けつけたときには、そのことが例えば電子音「ピピッ」などで報知部７より報知される（Ｓ１０３Ｎ、Ｓ１０４のＮ、Ｓ１０３のＹ、Ｓ１０５）。そして、便蓋２０の開止を待って、便蓋２０は反転し閉動作（以下、「反転閉動作」という）が開始され、便蓋２０が閉止すれば、そのことが電子音「ピッ」などで報知され、ボウル１２の洗浄が実行される（Ｓ１０６～Ｓ１０９）。 When a cleaning instruction is received before the toilet lid 20 is in the open state, the notification unit 7 notifies the cleaning instruction by, for example, an electronic sound "pip" (S103N, N of S104, Y of S103, S105). Then, waiting for the toilet lid 20 to open and close, the toilet lid 20 reverses and the closing operation (hereinafter referred to as "reversing closing operation") is started, and when the toilet lid 20 closes, that is an electronic sound "pip". The bowl 12 is washed (S106 to S109).
　ようするに、人のトイレ室への入室で便蓋２０は自動で開動作をするが、その開動作中に洗浄指示を受けつければ即、便蓋２０は反転閉動作をなし、便蓋２０の閉止を待って洗浄が実行される。このように、入室時の便蓋２０開動作中の洗浄指示であっても、便蓋２０閉止、洗浄という、飛沫の飛散防止のためのシーケンス動作は実行される。 As a result, the toilet lid 20 automatically opens when a person enters the toilet room, but as soon as a cleaning instruction is received during the opening operation, the toilet lid 20 reverses and closes, and the toilet lid 20 closes. Waiting for the cleaning to be performed. In this way, even if the cleaning instruction is given during the operation of opening the toilet lid 20 at the time of entering the room, the sequence operation of closing the toilet lid 20 and cleaning to prevent the scattering of droplets is executed.
　入室の際に、便の流し忘れや種々の理由により、まずボウル１２を洗浄しようと、開動作中に洗浄操作などで洗浄指示を受けた場合であっても、汚染物質の飛散防止を図ることのできる洗浄を実行することができる。 When entering the room, even if you try to wash the bowl 12 first due to forgetting to flush the stool or for various reasons, even if you receive a cleaning instruction during the cleaning operation during the opening operation, prevent the scattering of contaminants. Can perform cleaning.
　また、図４のステップＳ２００～Ｓ２０９の動作については、図３のシーケンス動作（Ｓ１０７、Ｓ１０９）に関する部分が異なる。図４では、厳密な意味でのシーケンス動作を実行せず、便蓋２０の反転閉動作の開始と同時（直後）に洗浄が実行される（Ｓ２０７、Ｓ２０８）。なお、洗浄開始の前に便蓋２０は閉止しないので、便蓋２０の閉止の報知はされなくてもよい。 Further, regarding the operation of steps S200 to S209 of FIG. 4, the part related to the sequence operation (S107, S109) of FIG. 3 is different. In FIG. 4, the sequence operation in a strict sense is not executed, and the washing is executed at the same time (immediately after) as the start of the reverse closing operation of the toilet lid 20 (S207, S208). Since the toilet lid 20 is not closed before the start of washing, it is not necessary to notify the closure of the toilet lid 20.
　この動作態様によれば、入室の際の洗浄指示により便蓋２０の反転閉動作は実行されるが、洗浄開始は便蓋２０の閉止を待たずになされる。そのため、洗浄指示から洗浄が終了するまでの時間が短縮される。流し忘れの発生がほとんどないような便器装置１の場合、このような動作態様にすればよい。なお、洗浄の際の飛沫の飛散防止を少しでも図れるように、図３と図４の中間的な動作態様として、図４の洗浄（Ｓ２０８）の開始を、便蓋２０の反転閉動作の開始（Ｓ２０７）から、所定時間（例えば２秒）の経過後に行うようにしてもよい。そうすれば、閉まりかけた便蓋２０により飛沫の拡散をわずかながらも和らげることができる。 According to this operation mode, the reverse closing operation of the toilet lid 20 is executed according to the cleaning instruction at the time of entering the room, but the cleaning is started without waiting for the closing of the toilet lid 20. Therefore, the time from the cleaning instruction to the completion of cleaning is shortened. In the case of the toilet bowl device 1 in which there is almost no occurrence of forgetting to flush, such an operation mode may be used. In addition, as an intermediate operation mode between FIGS. 3 and 4, the start of the cleaning (S208) of FIG. 4 and the start of the reverse closing operation of the toilet lid 20 are started so that the scattering of droplets during cleaning can be prevented as much as possible. It may be performed after a predetermined time (for example, 2 seconds) has elapsed from (S207). Then, the stool lid 20 that is about to close can soften the spread of the droplets, albeit slightly.
　また、便蓋２０の開／閉動作が途中で停止可能な便蓋機構、つまり便蓋２０が開止する前の中途段階で停止可能な機構を用いれば、便蓋２０が開状態となる前に便蓋２０の反転閉動作を実行することができ、洗浄を早めることができる。 Further, if a toilet lid mechanism capable of stopping the opening / closing operation of the toilet lid 20 in the middle, that is, a mechanism capable of stopping in the middle stage before the toilet lid 20 is opened, the toilet lid 20 is before the opening state. The stool lid 20 can be reversed and closed, and cleaning can be accelerated.
　また、図５のステップＳ３００～Ｓ３０７に示した動作態様のように、洗浄指示を取り消す動作態様としてもよい。すなわち、この動作態様では、入室後の便蓋２０の開動作中に洗浄指示を受けつけた場合、便蓋２０は開状態となるが、その後の便蓋２０の反転閉動作および洗浄は実行されず、洗浄指示がキャンセルされる（Ｓ３０２、Ｓ３０３のＹ、Ｓ３０５、Ｓ３０６）。その後、洗浄指示が取り消されたことが電子音「ピピッ、ピピッ」などで報知されればよい（Ｓ３０７）。なお、図５の動作フローにおいて、洗浄の取り消し自体は洗浄を実行しないロジックとしているだけであり、洗浄の取り消しの特別な処理を行うわけではないため、洗浄取り消しは破線で示した（Ｓ３０６）。 Further, as in the operation mode shown in steps S300 to S307 of FIG. 5, the operation mode may be such that the cleaning instruction is canceled. That is, in this operation mode, when a cleaning instruction is received during the opening operation of the toilet lid 20 after entering the room, the toilet lid 20 is opened, but the subsequent reverse closing operation and cleaning of the toilet lid 20 are not executed. , The cleaning instruction is canceled (Y, S305, S306 of S302, S303). After that, it may be notified by an electronic sound "pip, pip" or the like that the cleaning instruction has been canceled (S307). In the operation flow of FIG. 5, the washing cancellation itself is a logic that does not execute the washing, and does not perform a special process of the washing cancellation. Therefore, the washing cancellation is shown by a broken line (S306).
　このように、入室直後の洗浄指示を例外的な指示と捉えて、その洗浄指示をキャンセルするようにしてもよい。便蓋２０の開動作中の洗浄指示が使用者によるものであれば、その指示は取り消されるが、便蓋２０の開状態となった後、使用者が便蓋操作部２３を再操作すればよく、なんら問題はない。 In this way, the cleaning instruction immediately after entering the room may be regarded as an exceptional instruction and the cleaning instruction may be canceled. If the cleaning instruction during the opening operation of the toilet lid 20 is given by the user, the instruction is canceled, but if the user re-operates the toilet lid operation unit 23 after the toilet lid 20 is opened. Well, there is no problem.
　なお、以上に示した人体検知の際の動作態様における洗浄指示は、使用者が入室後すぐに行う便蓋操作部２３の操作によるものがおもに考えられるが、タイマー設定による自動洗浄（自動洗浄機能）による洗浄指示が含まれてもよい。つまり、入室の際の便蓋２０の開動作と、タイマー洗浄の洗浄指示とが重なった場合にも、図３～図５のいずれかの動作が実行されるようにしてもよい。 It should be noted that the cleaning instruction in the operation mode at the time of human body detection shown above is mainly considered to be the operation of the toilet lid operation unit 23 immediately after the user enters the room, but the automatic cleaning by the timer setting (automatic cleaning function). ) May include cleaning instructions. That is, even when the opening operation of the toilet lid 20 at the time of entering the room and the cleaning instruction of the timer cleaning overlap, any of the operations of FIGS. 3 to 5 may be executed.
　また、人体検知後における便蓋２０の開動作中の洗浄指示が、人の操作によるものか、またはタイマー洗浄によるものかを判別し、操作による場合は洗浄取り消しとし、タイマー洗浄による場合はシーケンス動作（反転閉動作、洗浄）を実行する構成としてもよい。 Further, it is determined whether the cleaning instruction during the opening operation of the toilet lid 20 after the detection of the human body is due to a human operation or a timer cleaning, and if the operation is performed, the cleaning is canceled, and if the timer cleaning is performed, the sequence operation is performed. It may be configured to execute (reverse closing operation, cleaning).
　便器装置１は以上のものに限られず、便座２４と便蓋２０とが一体として取り替え可能なものであってもよい。特に図６に示すような便座装置３０が後付けされた（あるいは取り替えられた）便器装置３であってもよい。図６（ａ）（ｂ）にもとづいて、本発明の他の実施形態に係る便器装置３の基本構成について説明する。なお本実施形態では、図６（ｂ）に可動式のトラップ１７Ａを例示したが、便器本体がサイホン式のトラップ１７（図２（ａ）参照）を有したものや、その他の方式のものにも適用は可能である。 The toilet device 1 is not limited to the above, and the toilet seat 24 and the toilet lid 20 may be interchangeable as a unit. In particular, the toilet device 3 to which the toilet seat device 30 as shown in FIG. 6 is retrofitted (or replaced) may be used. Based on FIGS. 6A and 6B, the basic configuration of the toilet bowl device 3 according to another embodiment of the present invention will be described. In this embodiment, the movable trap 17A is illustrated in FIG. 6 (b), but the toilet bowl body may have a siphon type trap 17 (see FIG. 2 (a)) or another method. Is also applicable.
　具体的には便器装置３は、ボウル１２と、ボウル１２へ洗浄水を供給しボウル１２内を洗浄する便器洗浄部１３と、便座装置３０と、便器洗浄部１３に対し洗浄の指示を出力する洗浄操作部２９とを備えている。便器装置３はさらに、制御部５と、報知部７と、人体検知部９とを備えている。 Specifically, the toilet device 3 outputs a cleaning instruction to the bowl 12, the toilet cleaning unit 13 that supplies cleaning water to the bowl 12 to clean the inside of the bowl 12, the toilet seat device 30, and the toilet cleaning unit 13. It is provided with a cleaning operation unit 29. The toilet device 3 further includes a control unit 5, a notification unit 7, and a human body detection unit 9.
　便座装置３０は、便器装置３の便器本体（便座装置３０を除く部位）とは着脱可能な別体とされている。便座装置３０は、便蓋４０、便蓋開閉検知部４１、便蓋駆動部４２、便蓋操作部４３、便座４４、便座開閉検知部４５、便座駆動部４６、便座操作部４７、着座検知部４８、ボウル洗浄操作部４９、便座側制御部３５、報知部３７を備えている。また、便座装置３０、便器本体間では信号の送受が可能とされている。 The toilet seat device 30 is a separate body that can be attached to and detached from the toilet bowl main body (part excluding the toilet seat device 30) of the toilet bowl device 3. The toilet seat device 30 includes 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, and a seating detection unit. It includes 48, a bowl cleaning operation unit 49, a toilet seat side control unit 35, and a notification unit 37. Further, it is possible to send and receive a signal between the toilet seat device 30 and the toilet bowl main body.
　なお、便座装置３０を除く便器装置３（便器本体）の構成は図１のものとおおむね同様であるため、詳細な説明は省略する。また、便座装置３０が備える、便蓋４０、便蓋開閉検知部４１、便蓋駆動部４２、便蓋操作部４３、便座４４、便座開閉検知部４５、便座駆動部４６、便座操作部４７、着座検知部４８についても図１のものとおおむね同様であり、その説明を省略する。 Since the configuration of the toilet bowl device 3 (toilet bowl main body) excluding the toilet seat device 30 is almost the same as that of FIG. 1, detailed description is omitted. Further, the toilet lid 40, the toilet lid open / close detection unit 41, the toilet lid drive unit 42, the toilet lid operation unit 43, the toilet seat 44, the toilet seat open / close detection unit 45, the toilet seat drive unit 46, and the toilet seat operation unit 47, which are included in the toilet seat device 30. The seating detection unit 48 is almost the same as that of FIG. 1, and the description thereof will be omitted.
　図６の便座装置３０は、便座装置３０側より便器洗浄部１３に対しボウル１２の洗浄指示が出力できる構成とされている。具体的には、便座装置３０は、ボウル洗浄操作部４９より洗浄の指示があったときに、便座側制御部３５がこれを受けて、便器本体側の制御部５を通じて、便器洗浄部１３を制御してボウル１２の洗浄ができるようになっている。また、便座側制御部３５が直接、便器洗浄部１３を制御する構成としてもよい。 The toilet seat device 30 of FIG. 6 has a configuration in which a cleaning instruction of the bowl 12 can be output from the toilet seat device 30 side to the toilet bowl cleaning unit 13. Specifically, in the toilet seat device 30, when the bowl cleaning operation unit 49 gives an instruction for cleaning, the toilet seat side control unit 35 receives the instruction, and the toilet seat cleaning unit 13 is moved through the control unit 5 on the toilet body side. The bowl 12 can be washed in a controlled manner. Further, the toilet seat side control unit 35 may be configured to directly control the toilet bowl cleaning unit 13.
　なお、図６に示すように、便器装置３は便座装置３０側のボウル洗浄操作部４９だけではなく、便器本体側の洗浄操作部２９をも含んだ構成とされている。つまり、図５のものは、洗浄操作部２９、ボウル洗浄操作部４９のいずれでも洗浄指示ができる構成とされている。また、便器本体側に洗浄操作部２９を設けずに、ボウル洗浄操作部４９でのみ洗浄指示ができる構成であってもよい。なお、ボウル洗浄操作部４９も大便用洗浄ボタンと小便用洗浄ボタンとを有することが望ましい。 As shown in FIG. 6, the toilet bowl device 3 includes not only the bowl cleaning operation unit 49 on the toilet seat device 30 side but also the cleaning operation unit 29 on the toilet bowl main body side. That is, the one in FIG. 5 has a configuration in which a cleaning instruction can be given by either the cleaning operation unit 29 or the bowl cleaning operation unit 49. Further, the cleaning operation unit 29 may not be provided on the toilet bowl main body side, and the cleaning instruction may be given only by the bowl cleaning operation unit 49. It is desirable that the bowl cleaning operation unit 49 also has a stool cleaning button and a urine cleaning button.
　ボウル洗浄操作部４９の操作はボウル洗浄指示手段として作用するが、さらに、着座検知部４８により検知された、着座中から離座への状態変化もボウル洗浄指示手段として作用する。つまり、着座中のときに便座４４から立ち上がった際には、洗浄ボタンの操作に代えて自動洗浄がなされる。 The operation of the bowl cleaning operation unit 49 acts as a bowl cleaning instruction means, and further, the state change from sitting to leaving the seat detected by the seating detection unit 48 also acts as a bowl cleaning instruction means. That is, when the person stands up from the toilet seat 44 while sitting, automatic cleaning is performed instead of operating the cleaning button.
　また、便器本体による洗浄指示には、図１に示した便器装置１と同様、タイマー設定による洗浄指示が含まれており、便座装置３０は、ボウル洗浄指示手段や便器本体の洗浄操作部２９による洗浄指示の他、タイマー設定による洗浄指示も受けつける。 Further, the cleaning instruction by the toilet bowl body includes a cleaning instruction by a timer setting as in the toilet bowl device 1 shown in FIG. 1, and the toilet seat device 30 is provided by the bowl cleaning instruction means and the cleaning operation unit 29 of the toilet bowl body. In addition to cleaning instructions, it also accepts cleaning instructions set by the toilet.
　この便器装置３も、人体が検知されたときには、図１の便器装置１と同様、図３～図５などの動作が可能とされる。ようするに、人体検知の際の便蓋２０の開動作中に洗浄指示があったときには、便蓋２０の閉動作、洗浄のシーケンス動作がなされる。なお、図４の動作は便蓋２０の閉動作が終了した後の洗浄ではなく、厳密にはシーケンス動作ではない。 When a human body is detected, the toilet device 3 can also operate as shown in FIGS. 3 to 5 as in the toilet device 1 of FIG. When a cleaning instruction is given during the opening operation of the toilet lid 20 at the time of detecting the human body, the toilet lid 20 is closed and the cleaning sequence operation is performed. It should be noted that the operation of FIG. 4 is not a cleaning operation after the closing operation of the toilet lid 20 is completed, and is not strictly a sequence operation.
　また、便器装置３の動作態様としては、図５の動作が実行されるようにしてよい。つまり、この動作態様では、人体検知の際の便蓋２０の開動作中に洗浄指示があったときには、便蓋２０の閉動作のみが実行され、洗浄指示はキャンセルされる。 Further, as the operation mode of the toilet bowl device 3, the operation shown in FIG. 5 may be executed. That is, in this operation mode, when a cleaning instruction is given during the opening operation of the toilet lid 20 at the time of detecting the human body, only the closing operation of the toilet lid 20 is executed, and the cleaning instruction is canceled.
　以上のように、本便座装置３０は、便座４４と、便蓋４０と、便蓋４０の開閉を検知する便蓋開閉検知部４１と、便蓋４０を開閉する便蓋駆動部４２と、を備えている。また便座装置３０は、便器本体に対し洗浄指示を出力するボウル洗浄指示手段と、便座側制御部３５と、を備えた、便器本体に取りつけられる装置である。そして便器本体は人体の検知が可能とされている。 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 for detecting the opening / closing of the toilet lid 40, and a toilet lid driving unit 42 for opening / closing the toilet lid 40. I have. Further, the toilet seat device 30 is a device attached to the toilet bowl body, which includes a bowl cleaning instruction means for outputting a cleaning instruction to the toilet bowl body and a toilet seat side control unit 35. And the body of the toilet bowl can detect the human body.
　また、便座側制御部３５は、便器本体が人体を検知したときに、便蓋２０が閉状態であれば、便蓋駆動部２２に便蓋２０の開動作を開始させ、便蓋２０が開動作中にボウル洗浄指示手段または便器本体より洗浄指示を受けた場合、つぎの動作を実行する。つまり便座側制御部３５は、便蓋駆動部２２に便蓋２０の閉動作を開始させ、その後、便器本体に対し洗浄指示を出力する。この動作は図３、図４に示したものに対応する。 Further, if the toilet lid 20 is in the closed state when the toilet bowl body detects the human body, the toilet seat side control unit 35 causes the toilet lid drive unit 22 to start the opening operation of the toilet lid 20, and the toilet lid 20 is opened. If a cleaning instruction is received from the bowl cleaning instruction means or the toilet body during the operation, the following operation is executed. That is, the toilet seat side control unit 35 causes the toilet lid driving unit 22 to start the closing operation of the toilet lid 20, and then outputs a cleaning instruction to the toilet bowl main body. This operation corresponds to that shown in FIGS. 3 and 4.
　一方、便座側制御部３５は、便器本体が人体を検知したときに、便蓋２０が閉状態であれば、便蓋駆動部２２に便蓋２０の開動作を開始させ、便蓋２０が開動作中にボウル洗浄指示手段または便器本体より洗浄指示を受けた場合、当該洗浄指示を取り消してもよい。この動作は図５に示したものに対応する。 On the other hand, if the toilet lid 20 is in the closed state when the toilet bowl body detects the human body, the toilet seat side control unit 35 causes the toilet lid drive unit 22 to start the opening operation of the toilet lid 20, and the toilet lid 20 is opened. If a cleaning instruction is received from the bowl cleaning instruction means or the toilet body during operation, the cleaning instruction may be canceled. This operation corresponds to that shown in FIG.
　便器装置３の動作における洗浄指示タイミングの報知や、便蓋４０の閉止タイミングの報知などの種々の報知については、便座装置３０の報知部３７、便器本体の報知部７のいずれで行ってもよい。 Various notifications such as notification of the cleaning instruction timing in the operation of the toilet bowl device 3 and notification of the closing timing of the toilet lid 40 may be performed by either the notification unit 37 of the toilet seat device 30 or the notification unit 7 of the toilet bowl body. ..
　なお、便座装置３０としては図６のものには限らない。便座装置３０としては例えば、局部洗浄装置を備えた構成であってもよいし、種々（例えば局部洗浄装置）の操作や設定ができる便座用操作部（不図示）を有する構成であってもよい。 The toilet seat device 30 is not limited to that shown in FIG. The toilet seat device 30 may be configured to include, for example, a local cleaning device, or may have a configuration having a toilet seat operation unit (not shown) capable of various operations and settings (for example, the local cleaning device). ..
