　吐出部４６は、本実施の形態では、便座２２の裏面２２ａに便座２２と一体に形成されている。吐出部４６は、分岐路４８ｂと繋がる流入口（不図示）と、洗浄液を吐出するための吐出口４６ａと、流入口と吐出口４６ａとを連通する連通孔（不図示）と、を有する。 In the present embodiment, the discharge portion 46 is formed integrally with the toilet seat 22 on the back surface 22a of the toilet seat 22. The discharge part 46 has an inlet (not shown) connected to the branch path 48b, an outlet 46a for discharging the cleaning liquid, and a communication hole (not shown) that connects the inlet and the outlet 46a.
　開閉弁５０が給液路４８を開くと、給液路４８から吐出部４６に洗浄液が供給され、吐出部４６の吐出口４６ａから便座２２の裏面２２ａを伝うように洗浄液が吐出される。これにより、便座２２の裏面２２ａが洗浄される。開閉弁５０が給液路を閉じると、給液路４８から吐出部４６への洗浄液の供給が停止し、吐出部４６からの洗浄液の吐出が停止する。 When the on-off valve 50 opens the liquid supply path 48, the cleaning liquid is supplied from the liquid supply path 48 to the discharge unit 46, and the cleaning liquid is discharged from the discharge port 46 a of the discharge unit 46 to the back surface 22 a of the toilet seat 22. Thereby, the back surface 22a of the toilet seat 22 is washed. When the on-off valve 50 closes the liquid supply path, the supply of the cleaning liquid from the liquid supply path 48 to the discharge unit 46 is stopped, and the discharge of the cleaning liquid from the discharge unit 46 is stopped.
　図４は、便器装置１０の一部を拡大して示す拡大断面図である。図４の便座２２の断面図は、図３のＡ－Ａ線断面図に対応する。図３に加えて図４を参照する。シール部材６０は、ゴム等の弾性体である。シール部材６０は、例えば接着剤により、便座２２の裏面２２ａに固定される。シール部材６０は、吐出部４６の外側すなわち吐出部４６に対して中央開口部３２とは反対側に設けられ、便座２２が閉状態にあるときには便座２２と便鉢１２とに挟み込まれ、便座裏洗浄において洗浄液が便座２２と便鉢１２との間から外に漏れ出るのを抑制する。シール部材６０は、好ましくは、図３に示すように環状に形成され、中央開口部３２およびすべての吐出部４６環囲するように便座２２の裏面２２ａに固定され、便座２２が閉状態にあるときには全周にわたって便座２２と便鉢１２とに挟み込まれる。 FIG. 4 is an enlarged cross-sectional view showing a part of the toilet device 10 in an enlarged manner. The sectional view of the toilet seat 22 in FIG. 4 corresponds to the sectional view along the line AA in FIG. Refer to FIG. 4 in addition to FIG. The seal member 60 is an elastic body such as rubber. The seal member 60 is fixed to the back surface 22a of the toilet seat 22 by, for example, an adhesive. The seal member 60 is provided on the outer side of the discharge part 46, that is, on the side opposite to the central opening 32 with respect to the discharge part 46, and is sandwiched between the toilet seat 22 and the toilet bowl 12 when the toilet seat 22 is in the closed state. The cleaning liquid is prevented from leaking from between the toilet seat 22 and the toilet bowl 12 during cleaning. The seal member 60 is preferably formed in an annular shape as shown in FIG. 3 and is fixed to the back surface 22a of the toilet seat 22 so as to surround the central opening 32 and all the discharge portions 46, and the toilet seat 22 is in a closed state. Sometimes it is sandwiched between the toilet seat 22 and the toilet bowl 12 over the entire circumference.
　例えば製造誤差により、便鉢１２および便座２２のシール部材６０との接触面が平坦でないことがある。この場合、単に便座２２を閉状態にしただけでは、シール部材６０と便座２２および／または便鉢１２との間に隙間が生じ、この隙間から洗浄液が漏れ出しうる。そこで、少なくとも便座裏洗浄中は、便座２２を便鉢１２に対して押し付けて（付勢して）シール部材６０と便座２２および便鉢１２との密着度を上げる、すなわちシール部材６０と便座２２および便鉢１２との隙間を低減する。本実施の形態では、後述のように便座裏洗浄中は便座開閉モータ４０を便座２２を閉じる方向に回転させ続ける。これにより、便座２２を便鉢１２に押し付けた状態が維持される。 For example, due to manufacturing errors, the contact surface of the toilet bowl 12 and the toilet seat 22 with the seal member 60 may not be flat. In this case, if the toilet seat 22 is simply closed, a gap is generated between the seal member 60 and the toilet seat 22 and / or the toilet bowl 12, and the cleaning liquid may leak from this gap. Therefore, at least during toilet seat back cleaning, the toilet seat 22 is pressed (biased) against the toilet bowl 12 to increase the adhesion between the seal member 60, the toilet seat 22 and the toilet bowl 12, that is, the seal member 60 and the toilet seat 22 And the gap with the toilet bowl 12 is reduced. In the present embodiment, the toilet seat opening / closing motor 40 is continuously rotated in the direction of closing the toilet seat 22 during the toilet seat back cleaning as described later. Thereby, the state which pressed the toilet seat 22 against the toilet bowl 12 is maintained.
　ここで、一般的に、便座２２は樹脂で形成され、便鉢１２は陶器で形成される。陶器は樹脂よりも加工精度が低く、したがって、便鉢１２の製造誤差は比較的大きい。また、シール部材６０と便座２２とは、接着剤等により固定する際に、それらの間に隙間が生じないように固定すればよい。そこで本実施の形態では、少なくとも便鉢１２の公差（例えば３ｍｍ～７ｍｍ）以上にシール部材６０がつぶれてシール部材６０と便鉢１２との密着度が上がるように、すなわちシール部材６０と便鉢１２との隙間が低減されるように、シール部材６０の硬度と便座２２を便鉢１２に対して押し付ける押し付け力を決定する。これらは、実験により決定されればよい。 Here, generally, the toilet seat 22 is formed of resin, and the toilet bowl 12 is formed of pottery. The pottery has a lower processing accuracy than the resin, and therefore the manufacturing error of the toilet bowl 12 is relatively large. Moreover, what is necessary is just to fix the sealing member 60 and the toilet seat 22 so that a clearance gap may not arise between them, when fixing with an adhesive agent etc. Therefore, in the present embodiment, the seal member 60 is crushed to at least the tolerance (for example, 3 mm to 7 mm) of the toilet bowl 12 to increase the degree of adhesion between the seal member 60 and the toilet bowl 12, that is, the seal member 60 and the toilet bowl. 12, the hardness of the seal member 60 and the pressing force for pressing the toilet seat 22 against the toilet bowl 12 are determined. These may be determined by experiments.
　変形例として、シール部材６０は便鉢１２の上面１２ａに固定されてもよい。この場合も、シール部材６０は、好ましくは、環状に形成され、便座２２が閉状態にあるときにすべての吐出部４６を環囲し、全周にわたって便座２２と便鉢１２とに挟み込まれるように設けられる。 As a modification, the seal member 60 may be fixed to the upper surface 12a of the toilet bowl 12. Also in this case, the seal member 60 is preferably formed in an annular shape so as to surround all the discharge portions 46 when the toilet seat 22 is in the closed state, and is sandwiched between the toilet seat 22 and the toilet bowl 12 over the entire circumference. Provided.

　便器装置１０は、人体検知センサ５２と、接触検知センサ（着座検知センサ）５４と、開閉検知センサ５６と、制御部７０と、をさらに含む。 The toilet device 10 further includes a human body detection sensor 52, a contact detection sensor (sitting detection sensor) 54, an open / close detection sensor 56, and a control unit 70.
　人体検知センサ５２は、非接触で、所定の検知範囲内にいる人体（ユーザ）を検知する。本実施の形態では、人体検知センサ５２は、トイレルーム（個室）内にいるユーザを検知するよう構成される。人体検知センサ５２は、便座２２および便蓋２４の開閉状態を問わず人体を検出可能な位置に設けられる。人体検知センサ５２は、検知結果を制御部７０に送信する。 The human body detection sensor 52 detects a human body (user) in a predetermined detection range without contact. In the present embodiment, the human body detection sensor 52 is configured to detect a user in a toilet room (private room). The human body detection sensor 52 is provided at a position where the human body can be detected regardless of whether the toilet seat 22 and the toilet lid 24 are opened or closed. The human body detection sensor 52 transmits the detection result to the control unit 70.
　接触検知センサ５４は、例えば静電センサであり、便座２２へのユーザの接触を検知する。具体的には接触検知センサ５４は、ユーザが便座２２に着座してユーザの臀部が便座２２に触れると接触（着座）を検知する。また接触検知センサ５４は、ユーザが便座２２を上げようとしてユーザの手が便座２２に触れたりすると、接触を検知する。接触検知センサ５４は、検知結果を制御部７０に送信する。 The contact detection sensor 54 is an electrostatic sensor, for example, and detects a user's contact with the toilet seat 22. Specifically, the contact detection sensor 54 detects contact (sitting) when the user is seated on the toilet seat 22 and the user's buttocks touches the toilet seat 22. The contact detection sensor 54 detects contact when the user's hand touches the toilet seat 22 while the user tries to raise the toilet seat 22. The contact detection sensor 54 transmits the detection result to the control unit 70.
　開閉検知センサ５６は、例えば角度センサであり、便座２２の開閉を検知する。開閉検知センサ５６は、検知結果を制御部７０に送信する。 The opening / closing detection sensor 56 is, for example, an angle sensor, and detects opening / closing of the toilet seat 22. The open / close detection sensor 56 transmits the detection result to the control unit 70.
　制御部７０は、通信部７２と、動作制御部７４と、記憶部７６と、を含む。通信部７２は、リモートコントロール装置８から送信された無線信号を受信して、ユーザによる便器装置１０に対する操作内容を特定する。 The control unit 70 includes a communication unit 72, an operation control unit 74, and a storage unit 76. The communication unit 72 receives the radio signal transmitted from the remote control device 8 and specifies the operation content for the toilet device 10 by the user.
　動作制御部７４は、便座裏洗浄機構４２による便座裏洗浄の開始と停止を制御する。また、動作制御部７４は、便座裏洗浄後に乾燥装置２８による便座裏の乾燥を制御する。以下、具体的に説明する。 The operation control unit 74 controls the start and stop of toilet seat back cleaning by the toilet seat back cleaning mechanism 42. Further, the operation control unit 74 controls the drying of the back of the toilet seat by the drying device 28 after the toilet seat back is washed. This will be specifically described below.
　便座裏洗浄の開始制御について説明する。動作制御部７４は、便座２２が閉状態にあり、かつ、例えば以下のＡ１～Ａ４のいずれかの開始条件が成立すると、便座裏洗浄を開始させる。具体的には動作制御部７４は、まず便座２２を閉じるときに便座開閉モータ４０の回転軸４０ａを回転させる回転方向に回転軸４０ａを回転させ続ける。これにより、便座２２が便鉢１２に対して押し付けられ、シール部材６０と便座２２および便鉢１２との密着度が上がる。動作制御部７４は、この状態で、開閉弁５０に給液路４８を開かせる。なおＡ２～Ａ４については、採用する開始条件をユーザが選択できてもよい。 The start control of toilet seat back cleaning will be explained. The operation control unit 74 starts cleaning the back of the toilet seat when the toilet seat 22 is in a closed state and, for example, any of the following start conditions A1 to A4 is satisfied. Specifically, when the toilet seat 22 is first closed, the operation control unit 74 continues to rotate the rotation shaft 40a in the rotation direction in which the rotation shaft 40a of the toilet seat opening / closing motor 40 is rotated. Thereby, the toilet seat 22 is pressed against the toilet bowl 12, and the adhesion between the sealing member 60, the toilet seat 22, and the toilet bowl 12 is increased. In this state, the operation control unit 74 causes the on-off valve 50 to open the liquid supply path 48. For A2 to A4, the user may be able to select a start condition to be adopted.
Ａ１．ユーザがリモートコントロール装置で便座裏洗浄の開始操作をした場合 A1. When the user starts cleaning the back of the toilet seat using the remote control device
Ａ２．あらかじめスケジュールされた便座裏洗浄の開始時刻になった場合
　便座裏洗浄を実行するスケジュールは予め記憶部７６に記憶される。動作制御部７４は、記憶部７６を定期的に参照し、スケジュールされた日時になると、便座裏洗浄を開始させる。便座裏洗浄は、例えば１日１回、決められた時刻に実行するようスケジュールされてもよいし、また例えば１週間に１回、決められた時刻に実行するようスケジュールされてもよいし、また例えば特定の曜日の決められた時刻に実行するようスケジュールされてもよい。 A2. When the start time of toilet seat back cleaning scheduled in advance is reached The schedule for executing toilet seat back cleaning is stored in the storage unit 76 in advance. The operation control unit 74 periodically refers to the storage unit 76 and starts cleaning the toilet seat back when the scheduled date and time comes. The toilet seat back wash may be scheduled to be performed at a fixed time, for example, once a day, or may be scheduled to be performed at a fixed time, for example, once a week, or For example, it may be scheduled to be executed at a predetermined time on a specific day of the week.
Ａ３．前回の便座裏洗浄の実行から所定時間が経過した場合
　動作制御部７４は、例えば便座裏洗浄の開始時刻を基準として、前回の便座裏洗浄から所定時間（例えば１時間、３時間または５時間）が経過した場合に実行する。この場合、所定時間は予め記憶部７６に記憶される。また、前回の便座裏洗浄の実行時刻（例えば開始時刻）も記憶部７６に記憶される。動作制御部７４は、記憶部７６を定期的に参照し、前回の便座裏洗浄の開始時刻から所定時間経過していた場合、便座裏洗浄を開始させる。動作制御部７４は、便座裏洗浄を開始すると、記憶部７６の実行時刻（開始時刻）を今回の時刻に更新する。 A3. When a predetermined time has elapsed since the previous cleaning of the back of the toilet seat The operation control unit 74 determines a predetermined time (for example, 1 hour, 3 hours, or 5 hours) from the previous cleaning of the back of the toilet seat based on, for example, the start time of the toilet seat back Executed when elapses. In this case, the predetermined time is stored in the storage unit 76 in advance. In addition, the previous execution time (for example, the start time) of toilet seat back cleaning is also stored in the storage unit 76. The operation control unit 74 refers to the storage unit 76 periodically, and starts a toilet seat back cleaning when a predetermined time has passed since the previous toilet seat back cleaning start time. When the toilet seat back cleaning is started, the operation control unit 74 updates the execution time (start time) of the storage unit 76 to the current time.
Ａ４．前回の便座裏洗浄後の便器装置１０の使用回数が所定回数に到達した場合
　動作制御部７４は、便器洗浄の回数を便器装置１０の使用回数と見なして便器装置１０の使用回数を数える。なお、便器洗浄とは、便鉢１２に洗浄水を供給して排泄された汚物を排出させるとともに便鉢１２を洗浄することをいう。便器装置１０の使用回数は、記憶部７６に記憶される。動作制御部７４は、便器洗浄が実行されるごとに、記憶部７６の使用回数を１インクリメントすると。動作制御部７４は、使用回数が所定回数に到達すると、便座裏洗浄を開始させるとともに、記憶部７６の使用回数を０にクリアする。例えば所定回数が１の場合は、便器装置１０の使用後に毎回、便座裏洗浄が実行され、所定回数が１０の場合は、１０回使用するごとに便座裏洗浄が実行される。 A4. When the number of uses of the toilet device 10 after the previous toilet seat back cleaning reaches a predetermined number of times The operation control unit 74 counts the number of uses of the toilet device 10 by regarding the number of times of toilet bowl cleaning as the number of uses of the toilet device 10. In addition, toilet bowl washing | cleaning means wash | cleaning the toilet bowl 12 while supplying the wash water to the toilet bowl 12, and discharging | emitting the excreta excreted. The number of uses of the toilet device 10 is stored in the storage unit 76. The operation control unit 74 increments the use count of the storage unit 76 by 1 each time toilet flushing is performed. When the number of uses reaches a predetermined number, the operation control unit 74 starts cleaning the toilet seat back and clears the number of uses in the storage unit 76 to zero. For example, when the predetermined number is 1, toilet seat back cleaning is performed every time after using the toilet device 10, and when the predetermined number is 10, toilet seat back cleaning is performed every time the toilet device 10 is used.
　動作制御部７４は、Ａ１～Ａ４のいずれかの開始条件が成立したにもかかわらず便座２２が開状態にあるときは、便座裏洗浄をスキップしてもよいが、便座開閉モータ４０を制御して便座２２を閉状態にし、便座裏洗浄を開始させてもよい。 The operation control unit 74 may control the toilet seat opening / closing motor 40 when the toilet seat 22 is in the open state even if any of the start conditions A1 to A4 is satisfied, but the toilet seat back washing may be skipped. Then, the toilet seat 22 may be closed and the toilet seat back cleaning may be started.
　また、ユーザがリモートコントロール装置で便座裏洗浄の開始操作した場合、その直後はユーザはトイレルームにいると考えられる。この場合、Ａ１～Ａ４のいずれかの開始条件が成立したにもかかわらず便座２２が開状態にあるときは、便座２２を閉じるようにユーザに通知してもよい。通知は、音声による通知であっても、リモートコントロール装置８の表示部８ｂを介した通知であってもよい。 In addition, when the user starts the toilet seat back cleaning operation with the remote control device, it is considered that the user is in the toilet room immediately after that. In this case, when the toilet seat 22 is in the open state even if any of the start conditions A1 to A4 is satisfied, the user may be notified to close the toilet seat 22. The notification may be a voice notification or a notification via the display unit 8b of the remote control device 8.
　次に、便座裏洗浄の停止制御について説明する。動作制御部７４は、以下のＢ１～Ｂ６のいずれかの停止条件が成立すると、便座裏洗浄を停止させる。具体的には動作制御部７４は、まず開閉弁５０に給液路４８を閉じさせる。そして動作制御部７４は、便座開閉モータ４０の回転軸４０ａの回転を停止させる。好ましくは動作制御部７４は、開閉弁５０を閉じてから所定時間が経過してから便座開閉モータ４０の回転軸４０ａの回転を停止させる。この所定時間には、すでに開閉弁５０を越えた給液路４８内の洗浄液が確実に流れきる時間が設定される。なおＢ４～Ｂ６については、採用する開始条件をユーザが選択できてもよい。 Next, stop control of toilet seat back cleaning will be described. The operation control unit 74 stops the toilet seat back cleaning when any of the following stop conditions B1 to B6 is satisfied. Specifically, the operation control unit 74 first causes the opening / closing valve 50 to close the liquid supply path 48. Then, the operation control unit 74 stops the rotation of the rotation shaft 40a of the toilet seat opening / closing motor 40. Preferably, the operation control unit 74 stops the rotation of the rotating shaft 40a of the toilet seat opening / closing motor 40 after a predetermined time has elapsed since the opening / closing valve 50 was closed. The predetermined time is set to a time during which the cleaning liquid in the liquid supply passage 48 that has already exceeded the on-off valve 50 can reliably flow. For B4 to B6, the user may be able to select a start condition to be adopted.
Ｂ１．決められた洗浄時間、便座裏洗浄を実行した場合 B1. When cleaning the back of the toilet seat for the specified cleaning time
Ｂ２．ユーザがリモートコントロール装置で便座裏洗浄の停止操作をした場合 B2. When the user stops the toilet seat back washing with the remote control device
Ｂ３．ユーザがリモートコントロール装置で便座２２を開状態にする操作をした場合
　動作制御部７４は、便座裏洗浄を停止させてから、便座開閉モータ４０を制御して便座２２を上げる。動作制御部７４は、開閉弁５０を閉じてから、吐出部４６からの吐出が確実に停止する所定期間が経過してから、便座２２を上げる。 B3. When the user performs an operation of opening the toilet seat 22 with the remote control device, the operation control unit 74 raises the toilet seat 22 by controlling the toilet seat opening / closing motor 40 after stopping the toilet seat back cleaning. The operation control unit 74 raises the toilet seat 22 after a predetermined period of time during which the discharge from the discharge unit 46 reliably stops after the on-off valve 50 is closed.
Ｂ４．人体検知センサ５２により人体が検知された場合
　トイレルーム内にユーザがいると、万が一に便座裏洗浄の洗浄液が中央開口部３２等から周囲に飛び散って、ユーザに洗浄液がかかるおそれがある。また、便座裏洗浄中は便座２２は便座開閉モータ４０により便鉢１２に押し付けられているが、ユーザが比較的大きな力をかければ便座２２を上げることができる。この場合、便座裏洗浄の洗浄液が周りに飛び散るおそれがある。そこで動作制御部７４は、人体検知センサ５２が人体を検知した場合、すなわちユーザがトイレルーム（個室）に入室してきた場合、便座裏洗浄を停止させる。 B4. When a human body is detected by the human body detection sensor 52 If there is a user in the toilet room, the cleaning liquid for cleaning the toilet seat back may scatter from the central opening 32 or the like to the user and the cleaning liquid may be applied to the user. While the toilet seat back is being washed, the toilet seat 22 is pressed against the toilet bowl 12 by the toilet seat opening / closing motor 40. However, if the user applies a relatively large force, the toilet seat 22 can be raised. In this case, the cleaning liquid for cleaning the back of the toilet seat may be scattered around. Therefore, when the human body detection sensor 52 detects the human body, that is, when the user enters the toilet room (private room), the operation control unit 74 stops the toilet seat back cleaning.
　ただし、トイレルーム内でユーザがリモートコントロール装置を操作して便座裏洗浄を開始させたときは、人体検知センサ５２が検知しても、便座裏洗浄を停止させない。なお、リモートコントロール装置を操作して便座裏洗浄を開始させた場合でも、開始から所定時間経過後は、便座裏洗浄を開始させたユーザとは別のユーザが入室してくる可能性があるため、人体検知センサ５２が検知した場合に便座裏洗浄を中止させてもよい。 However, when the user operates the remote control device in the toilet room to start cleaning the back of the toilet seat, the toilet seat cleaning is not stopped even if the human body detection sensor 52 detects it. Even if the toilet seat back cleaning is started by operating the remote control device, a user other than the user who started the toilet seat back cleaning may enter the room after a predetermined time has elapsed since the start. When the human body detection sensor 52 detects, the toilet seat back cleaning may be stopped.
Ｂ５．接触検知センサ５４によりユーザが便座２２に接触したことが検知された場合
　便座裏洗浄中にユーザが便座２２に着座すると、万が一に便座裏洗浄の洗浄液が中央開口部３２等から周囲に飛び散って着座しているユーザにかかるおそれがある。また、上述したように、便座裏洗浄中でもユーザが比較的大きな力をかければ便座２２を上げることができ、その場合、便座裏洗浄の洗浄液が周りに飛び散るおそれがある。そこで動作制御部７４は、接触検知センサ５４がユーザが便座２２に接触したことを検知した場合、便座裏洗浄を停止させる。 B5. When it is detected by the contact detection sensor 54 that the user has touched the toilet seat 22 If the user sits on the toilet seat 22 during the toilet seat back cleaning, the cleaning liquid for cleaning the toilet seat back is scattered from the central opening 32 or the like to the surroundings. This may affect the user who is working. Further, as described above, the toilet seat 22 can be raised if the user applies a relatively large force even during the toilet seat back cleaning. In this case, there is a possibility that the cleaning liquid for cleaning the toilet seat back will scatter around. Therefore, when the contact detection sensor 54 detects that the user has touched the toilet seat 22, the operation control unit 74 stops the toilet seat back cleaning.
Ｂ６．開閉検知センサ５６が便座２２が非閉状態になったことを検知した場合
　上述したように、便座裏洗浄中でもユーザが比較的大きな力をかければ便座２２を上げることができ、その場合、便座裏洗浄の洗浄液が周りに飛び散るおそれがある。そこで動作制御部７４は、開閉検知センサ５６が便座２２が非閉状態になったことを検知した場合、便座裏洗浄を停止させる。 B6. When the open / close detection sensor 56 detects that the toilet seat 22 is in a non-closed state, as described above, the toilet seat 22 can be raised if the user applies a relatively large force even during toilet seat back cleaning. There is a risk that the cleaning liquid for the cleaning may splash around. Therefore, when the open / close detection sensor 56 detects that the toilet seat 22 is not closed, the operation control unit 74 stops the toilet seat back cleaning.
　次に、便座裏洗浄後の乾燥制御について説明する。
　動作制御部７４は、便座裏洗浄機構４２による便座裏洗浄が停止すると、便座２２が閉状態であれば、乾燥装置２８に便座裏乾燥を実行させる。具体的には乾燥装置２８は、便座２２の裏面に乾燥風を吹き付ける。これにより、比較的大きい水滴は便鉢１２に落ちる。乾燥風の風圧により、便座２２の裏面に付着した洗浄液は乾燥風の下流に集まる。集まった洗浄液は比較的大きな水滴を形成し、乾燥風を受けて便鉢１２に落ちる。また、乾燥装置２８は、便座２２の裏面に乾燥風として温風を吹き付ける（送風する）。これにより、便座２２の裏面に付いた洗浄液は揮発する。なお、乾燥風の風速、温度、吹き付け時間は実験で定めることができる。 Next, the drying control after toilet seat back washing will be described.
When the toilet seat back cleaning by the toilet seat back cleaning mechanism 42 stops, the operation control unit 74 causes the drying device 28 to perform toilet seat back drying if the toilet seat 22 is closed. Specifically, the drying device 28 blows dry air on the back surface of the toilet seat 22. As a result, relatively large water drops fall on the toilet bowl 12. The cleaning liquid adhering to the back surface of the toilet seat 22 gathers downstream of the drying air due to the wind pressure of the drying air. The collected cleaning liquid forms relatively large water droplets and falls into the toilet bowl 12 after receiving dry air. The drying device 28 blows (blows) warm air as dry air on the back surface of the toilet seat 22. As a result, the cleaning liquid attached to the back surface of the toilet seat 22 volatilizes. In addition, the wind speed, temperature, and spraying time of the drying air can be determined by experiments.
　つづいて、本実施の形態が奏する効果について述べる。本実施の形態によれば、便座２２が非閉状態であるときは便座裏洗浄が実行されないため、便座裏洗浄において吐出部４６から吐出される洗浄液が便器装置１０の周囲に飛び散るのが抑止される。 Next, the effects of this embodiment will be described. According to the present embodiment, since the toilet seat back cleaning is not performed when the toilet seat 22 is in the non-closed state, the cleaning liquid discharged from the discharge unit 46 in the toilet seat back cleaning is prevented from being scattered around the toilet device 10. The
　また、本実施の形態によれば、便座裏洗浄中に人体検知センサ５２がユーザを検知すると、すなわちトイレルーム（個室）への入室を検知すると、便座裏洗浄が停止される。これにより、便座裏洗浄の洗浄液がユーザにかかるのを抑止できる。また、ユーザが便座裏洗浄中に便座２２を上げて洗浄液が便器装置１０の周囲に飛び散る、といった事態が生じるのを抑止できる。 Further, according to the present embodiment, when the human body detection sensor 52 detects the user during toilet seat cleaning, that is, when entering the toilet room (private room) is detected, the toilet seat cleaning is stopped. Thereby, it can suppress that the washing liquid of toilet seat back washing takes on a user. In addition, it is possible to prevent a situation in which the user raises the toilet seat 22 during cleaning of the back of the toilet seat and the cleaning liquid scatters around the toilet device 10.
　また、本実施の形態によれば、便座裏洗浄中に接触検知センサ（着座検知センサ）５４がユーザが便座２２に接触したことを検知すると、便座裏洗浄が停止される。例えば、ユーザが便座２２に着座すると便座裏洗浄が停止される。これにより、便座２２に着座したユーザに便座裏洗浄の洗浄液がかかってユーザに不快な思いをさせるのを抑止できる。また例えば、ユーザが便座２２を上げようと便座２２に触れると便座裏洗浄が停止される。これにより、ユーザが便座裏洗浄中に便座２２を上げて洗浄液が便器装置１０の周囲に飛び散る、といった事態が生じるのを抑止できる。 Further, according to the present embodiment, when the contact detection sensor (sitting detection sensor) 54 detects that the user has touched the toilet seat 22 during the toilet seat back cleaning, the toilet seat back cleaning is stopped. For example, when the user is seated on the toilet seat 22, the toilet seat back cleaning is stopped. As a result, it is possible to prevent the user sitting on the toilet seat 22 from applying the cleaning liquid for cleaning the toilet seat back to make the user feel uncomfortable. Further, for example, when the user touches the toilet seat 22 to raise the toilet seat 22, the toilet seat back cleaning is stopped. Thereby, it is possible to prevent a situation in which the user raises the toilet seat 22 during the toilet seat back cleaning and the cleaning liquid is scattered around the toilet device 10.
　また、本実施の形態によれば、便座裏洗浄中に開閉検知センサ５６が便座２２が非閉状態になったことを検知すると、便座裏洗浄が停止される。これにより、ユーザが便座２２を上げると便座裏洗浄が停止されるため、洗浄液が便器装置１０の周囲に飛び散るのを抑止できる。 Further, according to the present embodiment, when the opening / closing detection sensor 56 detects that the toilet seat 22 is not closed during the toilet seat back cleaning, the toilet seat back cleaning is stopped. Thereby, when the user raises the toilet seat 22, the toilet seat back cleaning is stopped, so that the cleaning liquid can be prevented from being scattered around the toilet device 10.
　また、本実施の形態によれば、便座裏洗浄中は、便座２２は便鉢１２に対して押し付けられ、言い換えると便座２２は閉方向に付勢される。これにより、便座２２を上げにくくなり、ユーザが便座裏洗浄中に便座２２を上げて洗浄液が便器装置１０の周囲に飛び散る、といった事態が生じるのを抑止できる。また、これにより、シール部材６０と便座２２および便鉢１２との密着度が上がり、便座裏洗浄の洗浄液が便座２２と便鉢１２との間から漏れ出るのが抑止される。 Further, according to the present embodiment, during the toilet seat back cleaning, the toilet seat 22 is pressed against the toilet bowl 12, in other words, the toilet seat 22 is biased in the closing direction. Thereby, it becomes difficult to raise the toilet seat 22, and it can be prevented that the user raises the toilet seat 22 during cleaning of the back of the toilet seat and the cleaning liquid is scattered around the toilet device 10. This also increases the degree of adhesion between the seal member 60 and the toilet seat 22 and the toilet bowl 12, and prevents the cleaning liquid for cleaning the toilet seat back from leaking between the toilet seat 22 and the toilet bowl 12.
　また、本実施の形態によれば、便座２２は便座開閉モータ４０によって閉方向に付勢される。つまり、便座２２を閉方向に付勢するための専用の機構を別途設けることなく、便座２２を閉方向に付勢できる。 Further, according to the present embodiment, the toilet seat 22 is urged in the closing direction by the toilet seat opening / closing motor 40. That is, the toilet seat 22 can be urged in the closing direction without separately providing a dedicated mechanism for urging the toilet seat 22 in the closing direction.
　また、本実施の形態によれば、好ましくは、シール部材６０は、環状に形成され、全周にわたって便座２２と便鉢１２とに挟み込まれる。これにより、便座裏洗浄の洗浄液が便座２２と便鉢１２との間から漏れ出るのをより確実に抑止できる。 Also, according to the present embodiment, preferably, the seal member 60 is formed in an annular shape and is sandwiched between the toilet seat 22 and the toilet bowl 12 over the entire circumference. Thereby, it can suppress more reliably that the washing | cleaning liquid of toilet seat back washing | cleaning leaks from between the toilet seat 22 and the toilet bowl 12. FIG.
　また、本実施の形態によれば、便座裏洗浄後に、乾燥装置２８により便座２２の裏面が乾燥される。これにより、便座２２の裏面に付着した洗浄液（水分）を起因とするカビや雑菌の発生を抑えられ、便器装置１０を清潔に保つことができる。 Further, according to the present embodiment, the back surface of the toilet seat 22 is dried by the drying device 28 after the toilet seat back is washed. Thereby, generation | occurrence | production of the mold | fungi and miscellaneous bacteria resulting from the washing | cleaning liquid (water | moisture content) adhering to the back surface of the toilet seat 22 can be suppressed, and the toilet device 10 can be kept clean.
　また、本実施の形態によれば、便座２２の裏面の乾燥では、乾燥風を便座２２の裏面に乾燥風を吹き付ける。これにより、便座２２の裏面に付着した比較的大きな洗浄液の水滴は便鉢１２に落ちる。また、乾燥風の風圧により、便座２２の裏面に付着した洗浄液は乾燥風の下流に集まる。集まった洗浄液は比較的大きな水滴を形成し、乾燥風を受けて便鉢１２に落ちる。その結果、便座２２の裏面は乾燥する。 Further, according to the present embodiment, in drying the back surface of the toilet seat 22, the drying air is blown on the back surface of the toilet seat 22. Thereby, a relatively large water droplet of the cleaning liquid adhering to the back surface of the toilet seat 22 falls on the toilet bowl 12. Further, due to the wind pressure of the drying air, the cleaning liquid adhering to the back surface of the toilet seat 22 gathers downstream of the drying air. The collected cleaning liquid forms relatively large water droplets and falls into the toilet bowl 12 after receiving dry air. As a result, the back surface of the toilet seat 22 is dried.
　また、本実施の形態によれば、便座２２の裏面の乾燥では、乾燥風として温風を便座２２の裏面に吹き付ける。これにより、便座２２の裏面に付着した洗浄液が揮発し、その結果、便座２２の裏面は乾燥する。 Further, according to the present embodiment, in drying the back surface of the toilet seat 22, warm air is blown as dry air on the back surface of the toilet seat 22. Thereby, the cleaning liquid adhering to the back surface of the toilet seat 22 volatilizes, and as a result, the back surface of the toilet seat 22 is dried.
　以上、実施の形態に係る便器装置１０について説明した。この実施の形態は例示であり、各構成要素の組み合わせにいろいろな変形例が可能なこと、またそうした変形例も本発明の範囲にあることは当業者に理解されるところである。 The toilet device 10 according to the embodiment has been described above. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to the combination of each component, and such modifications are also within the scope of the present invention.
（変形例１）
　図６は、変形例に実施の形態の便器装置１０を示す側面図である。本変形例では、ロック機構により便座裏洗浄中に便座２２が上げられるのを抑止し、またロック機構により便座２２を便鉢１２に対して押し付けてシール部材６０と便座２２および便鉢１２との密着度を上げる。以下、便器装置１０について実施の形態に係る便器装置１０との相違点を中心に説明する。 (Modification 1)
FIG. 6 is a side view showing the toilet device 10 of the embodiment as a modified example. In the present modification, the lock mechanism prevents the toilet seat 22 from being raised during cleaning of the toilet seat back, and the lock mechanism presses the toilet seat 22 against the toilet bowl 12 so that the seal member 60, the toilet seat 22 and the toilet bowl 12 Increase adhesion. Hereinafter, the toilet device 10 will be described focusing on differences from the toilet device 10 according to the embodiment.
　便器装置１０は、便器本体１４と、便座ユニット１６と、ボックス（不図示）と、便座裏洗浄機構（不図示）と、シール部材（不図示）と、ロック機構８０と、を備える。 The toilet device 10 includes a toilet body 14, a toilet seat unit 16, a box (not shown), a toilet seat back cleaning mechanism (not shown), a seal member (not shown), and a lock mechanism 80.
　ロック機構８０は、便座ユニット１６の後方に設けられる。ロック機構８０は、ロックピン８２と、駆動装置８４と、を含む。ロックピン８２は、前後方向に延在する棒状の部材であり、駆動装置８４を介して便器本体１４に固定される。駆動装置８４は、制御部７０の動作制御部７４に制御され、ロックピン８２を前後に移動させる。便座２２には、ロックピン８２が進入可能に構成された孔２２ｂが形成されている。ロックピン８２が便座２２の孔２２ｂに進入すると、便座２２は閉状態にロックされる。ロックピン８２が便座２２の孔２２ｂから退避すると、便座２２のロックが解除される。なお図６では、ロックピン８２が便座２２の孔２２ｂに進入し、便座２２が閉状態にロックされた状態を示している。 The lock mechanism 80 is provided behind the toilet seat unit 16. The lock mechanism 80 includes a lock pin 82 and a drive device 84. The lock pin 82 is a rod-like member extending in the front-rear direction, and is fixed to the toilet body 14 via the drive device 84. The drive device 84 is controlled by the operation control unit 74 of the control unit 70 and moves the lock pin 82 back and forth. The toilet seat 22 is formed with a hole 22b configured to allow the lock pin 82 to enter. When the lock pin 82 enters the hole 22b of the toilet seat 22, the toilet seat 22 is locked in the closed state. When the lock pin 82 is retracted from the hole 22b of the toilet seat 22, the lock of the toilet seat 22 is released. 6 shows a state in which the lock pin 82 enters the hole 22b of the toilet seat 22 and the toilet seat 22 is locked in the closed state.
　動作制御部７４は、実施の形態と同様に、便座２２が閉状態にあり、かつ、Ａ１～Ａ４のいずれかの開始条件が成立すると、便座裏洗浄を開始させる。具体的には動作制御部７４は、まず便座２２を閉じるときに便座開閉モータ４０の回転軸４０ａを回転させる回転方向に回転軸４０ａを回転させ続ける。これにより、便座２２が便鉢１２に対して押し付けられ、シール部材６０と便座２２および便鉢１２との密着度が上がる。動作制御部７４は、この状態で、ロック機構８０の駆動装置８４を制御して、ロックピン８２を孔２２ｂに進入させ、便座２２を閉状態にロックする。動作制御部７４は、便座開閉モータ４０の回転軸４０ａの回転を停止させる。便座２２はロック機構８０により便鉢１２に押し付けられた状態で維持されているため、便座開閉モータ４０の回転軸４０ａの回転を止めても、シール部材６０と便座２２および便鉢１２との密着度は上がったままとなる。そして動作制御部７４は、開閉弁５０に給液路４８を開かせる。 As in the embodiment, the operation control unit 74 starts cleaning the back of the toilet seat when the toilet seat 22 is in the closed state and any of the start conditions A1 to A4 is satisfied. Specifically, when the toilet seat 22 is first closed, the operation control unit 74 continues to rotate the rotation shaft 40a in the rotation direction in which the rotation shaft 40a of the toilet seat opening / closing motor 40 is rotated. Thereby, the toilet seat 22 is pressed against the toilet bowl 12, and the adhesion between the sealing member 60, the toilet seat 22, and the toilet bowl 12 is increased. In this state, the operation control unit 74 controls the drive device 84 of the lock mechanism 80 to cause the lock pin 82 to enter the hole 22b and lock the toilet seat 22 in the closed state. The operation control unit 74 stops the rotation of the rotation shaft 40a of the toilet seat opening / closing motor 40. Since the toilet seat 22 is maintained in a state of being pressed against the toilet bowl 12 by the lock mechanism 80, the sealing member 60, the toilet seat 22 and the toilet bowl 12 are in close contact with each other even when the rotation of the rotary shaft 40a of the toilet seat opening / closing motor 40 is stopped. The degree will stay up. Then, the operation control unit 74 causes the on-off valve 50 to open the liquid supply path 48.
　また、動作制御部７４は、実施の形態と同様に、Ｂ１～Ｂ６のいずれかの停止条件が成立すると、便座裏洗浄を停止させる。具体的には動作制御部７４は、開閉弁５０に給液路４８を閉じさせる。そして動作制御部７４は、ロックピン８２を孔２２ｂから退避させ、便座２２のロックを解除する。 Also, as in the embodiment, the operation control unit 74 stops the toilet seat back cleaning when any of the stop conditions B1 to B6 is satisfied. Specifically, the operation control unit 74 causes the opening / closing valve 50 to close the liquid supply path 48. Then, the operation control unit 74 retracts the lock pin 82 from the hole 22b and releases the lock of the toilet seat 22.
　便器装置１０によれば、実施の形態に係る便器装置１０と同様の作用効果を奏することができる。加えて、便器装置１０によれば、便器裏洗浄中に便座２２を上げられなくなるため、便座裏洗浄中にユーザが便座２２を上げて洗浄液が飛び散る、といった事態が生じるのを防ぐことができる。 According to the toilet device 10, the same operational effects as the toilet device 10 according to the embodiment can be obtained. In addition, according to the toilet device 10, since the toilet seat 22 cannot be raised during the toilet back cleaning, it is possible to prevent a situation in which the user raises the toilet seat 22 and the cleaning liquid is scattered during the toilet seat back cleaning.
（変形例２）
　実施の形態では、便座裏洗浄中は便座開閉モータ４０の回転軸４０ａを回転させ続けて便座２２を閉方向に付勢する場合について説明したが、便座２２を上げられるのを抑止する目的だけであれば、便座裏洗浄中で、かつ、人体検知センサ５２が人体を検知している場合だけ、すなわち便座裏洗浄中で、かつ、ユーザがトイレルームに入室している場合だけ、便座２２を閉方向に付勢してもよい。また、人体検知センサ５２が人体を検知していないときは便座開閉モータ４０の回転軸４０ａを比較的低い回転数で回転させ続け、人体検知センサ５２が人体を検知しているときは便座開閉モータ４０の回転軸４０ａを比較的高い回転数で回転させ続けてもよい。 (Modification 2)
In the embodiment, the case where the toilet shaft 22a is continuously rotated to rotate the rotating shaft 40a and the toilet seat 22 is urged in the closing direction during cleaning of the toilet seat back is described, but only for the purpose of preventing the toilet seat 22 from being raised. If there is, the toilet seat 22 is closed only when the back of the toilet seat is being cleaned and the human body detection sensor 52 is detecting a human body, that is, when the back of the toilet seat is being cleaned and the user is entering the toilet room. It may be biased in the direction. When the human body detection sensor 52 is not detecting a human body, the rotation shaft 40a of the toilet seat opening / closing motor 40 is continuously rotated at a relatively low rotational speed, and when the human body detection sensor 52 is detecting a human body, the toilet seat opening / closing motor is detected. Forty rotation shafts 40a may continue to rotate at a relatively high rotational speed.
　また、上述の変形例では、便座裏洗浄中は便座２２を上げられないようにロック機構８０によりロックする場合について説明したが、便座２２を上げられるのを抑止する目的だけであれば、便座裏洗浄中で、かつ、人体検知センサ５２が人体を検知している場合だけ、すなわち便座裏洗浄中で、かつ、ユーザがトイレルームに入室している場合だけ、便座２２を上げられないようにロックしてもよい。 Further, in the above-described modification, the case where the toilet seat 22 is locked by the lock mechanism 80 so that the toilet seat 22 cannot be raised during washing of the toilet seat back has been described. Locked so that the toilet seat 22 cannot be raised only during cleaning and when the human body detection sensor 52 detects a human body, that is, when the back of the toilet seat is being cleaned and the user has entered the toilet room. May be.
（変形例３）
　実施の形態および上述の変形例では、動作制御部７４は、便座裏洗浄に関して便蓋２４の開閉状態は問わなかったが、便蓋２４の開閉状態を便座裏洗浄の開始条件および停止条件に含めてもよい。具体的には、動作制御部７４は、便座２２が閉状態であっても便蓋２４が非閉状態であるときは、便座裏洗浄を開始させないこととしてもよい。つまり動作制御部７４は、便座２２だけでなく便蓋２４も閉状態であり、かつ、上述のＡ１～Ａ４のいずれかの開始条件が成立したときに、便座裏洗浄を開始させてもよい。また、動作制御部７４は、便座裏洗浄の実行中に便蓋２４が非閉状態とされた場合は、便座２２が閉状態であっても、便座裏洗浄を停止させてもよい。これらの場合、万が一に便座裏洗浄の洗浄液が便座２２の中央開口部３２等から飛び出ても、便蓋２４で受けられる。つまり、便座裏洗浄の洗浄液が便器装置１０の外に飛び散るのを抑止でき、トイレルームを清潔に保てる。 (Modification 3)
In the embodiment and the above-described modification, the operation control unit 74 does not matter whether the toilet lid 24 is opened or closed with respect to toilet seat back cleaning, but includes the opening / closing state of the toilet lid 24 in the toilet seat back cleaning start condition and stop condition. May be. Specifically, the operation control unit 74 may not start the toilet seat back cleaning when the toilet seat 24 is in the closed state and the toilet lid 24 is in the non-closed state. That is, the operation control unit 74 may start cleaning the toilet seat back when not only the toilet seat 22 but also the toilet lid 24 is in a closed state and any of the start conditions A1 to A4 is satisfied. Further, when the toilet lid 24 is not closed during the toilet seat back cleaning, the operation control unit 74 may stop the toilet seat back cleaning even if the toilet seat 22 is closed. In these cases, even if the cleaning liquid for cleaning the back of the toilet seat jumps out of the central opening 32 or the like of the toilet seat 22, it can be received by the toilet lid 24. That is, it is possible to prevent the toilet seat back cleaning liquid from splashing out of the toilet apparatus 10, and the toilet room can be kept clean.
（変形例４）
　実施の形態および上述の変形例では特に言及しなかったが、シール部材６０の構成には、様々な変形例が考えられる。図７（ａ）、（ｂ）はそれぞれ、変形例に係るシール部材６０とその周辺を示す断面図である。図７（ａ）、（ｂ）では、便座２２を便鉢１２に押し付ける前の状態を示している。 (Modification 4)
Although not particularly mentioned in the embodiment and the above-described modified examples, various modified examples of the configuration of the seal member 60 are conceivable. FIGS. 7A and 7B are cross-sectional views showing a seal member 60 and its periphery according to a modification, respectively. FIGS. 7A and 7B show a state before the toilet seat 22 is pressed against the toilet bowl 12.
　図７（ａ）では、シール部材６０は、便鉢１２側（固定されない側）が便座２２から離れるほど細くなるよう形成されている。この場合、シール部材６０の便鉢１２側は変形しやすく、シール部材６０を便座２２と便鉢１２とで挟み込んだときの密着度が上がる。 7A, the seal member 60 is formed so that the toilet bowl 12 side (side not fixed) becomes thinner as the toilet seat 22 is separated. In this case, the toilet bowl 12 side of the sealing member 60 is easily deformed, and the degree of adhesion when the sealing member 60 is sandwiched between the toilet seat 22 and the toilet bowl 12 is increased.
　図７（ｂ）では、シール部材６０は、ゴム製であり、便座２２側（固定されている側）の比較的硬度の高い（例えば硬度が６０度以上の）第１部分６０ａと、便鉢１２側の比較的硬度の低い（例えば硬度が３０以下の）第２部分６０ｂとが二色成形により一体化されている。この場合、硬度が高い第１部分６０ａは、便座２２が便鉢１２と直接接触しないように便座２２およびユーザの体重を受ける。硬度が低い第２部分６０ｂは、大きく変形して便鉢１２と密着する。 In FIG.7 (b), the sealing member 60 is the product made from rubber, the 1st part 60a with comparatively high hardness (for example, hardness is 60 degree | times or more) by the toilet seat 22 side (fixed side), and a toilet bowl A second portion 60b having a relatively low hardness (for example, a hardness of 30 or less) on the 12 side is integrated by two-color molding. In this case, the first portion 60 a having high hardness receives the weight of the toilet seat 22 and the user so that the toilet seat 22 does not directly contact the toilet bowl 12. The second portion 60b having a low hardness deforms greatly and comes into close contact with the toilet bowl 12.
（変形例５）
　図８は、変形例に係る便器装置の断面図である。図９は図４に対応する。便座２２の裏面２２ａのうち、便鉢１２の上面１２ａと対向する外側部分２２ａ１よりも内側の内側部分２２ａ２が、水平面に対して傾斜した傾斜面となるように形成される。図９の例では、内側部分２２ａの断面形状は逆Ｕ字状を有する。本変形例によれば、乾燥風を吹き付けると、内側部分２２ａに付着した洗浄液は傾斜面を伝って便鉢１２に落ちる。つまり、洗浄液が落ちやすくなる。 (Modification 5)
FIG. 8 is a cross-sectional view of a toilet device according to a modification. FIG. 9 corresponds to FIG. Of the back surface 22a of the toilet seat 22, the inner portion 22a2 inside the outer portion 22a1 facing the upper surface 12a of the toilet bowl 12 is formed to be an inclined surface inclined with respect to the horizontal plane. In the example of FIG. 9, the cross-sectional shape of the inner portion 22 a has an inverted U shape. According to this modification, when dry air is blown, the cleaning liquid adhering to the inner portion 22a falls on the toilet bowl 12 along the inclined surface. That is, the cleaning liquid is easily dropped.
（変形例６）
　図９は、変形例に係る便器装置の断面図である。図８は図４に対応する。本変形例では、便鉢１２は、外側上面１２ａ１と、外側上面１２ａ１の内側、かつ、下側に位置する内側上面１２ａ２と、を有する。外側上面１２ａ１と、内側上面１２ａ２とは、連結壁１２ｂにより連結されている。シール部材６０は、便座２２が閉位置にあるときに、便座２２の裏面２２ａと、内側上面１２ａ２とに挟み込まれる。この場合、仮にシール部材６０の外側に洗浄液が漏れ出ても、洗浄液は連結壁１２ｂによってせき止められる。つまり、本変形例によれば、洗浄液の漏れ出しをより確実に抑えることができる。 (Modification 6)
FIG. 9 is a cross-sectional view of a toilet device according to a modification. FIG. 8 corresponds to FIG. In the present modification, the toilet bowl 12 has an outer upper surface 12a1 and an inner upper surface 12a2 located on the inner side and lower side of the outer upper surface 12a1. The outer upper surface 12a1 and the inner upper surface 12a2 are connected by a connecting wall 12b. The seal member 60 is sandwiched between the back surface 22a of the toilet seat 22 and the inner upper surface 12a2 when the toilet seat 22 is in the closed position. In this case, even if the cleaning liquid leaks outside the seal member 60, the cleaning liquid is blocked by the connecting wall 12b. That is, according to this modification, it is possible to more reliably suppress the leakage of the cleaning liquid.
（変形例７）
　実施の形態では特に言及しなかったが、便座裏洗浄機構４２による便座裏洗浄には、洗浄態様が異なる複数の洗浄モードがあってもよい。例えば、便座裏洗浄機構４２による便座裏洗浄には、以下の少なくとも１つが異なる複数の洗浄モードがあってもよい。
　　・洗浄時間（すなわち洗浄液の吐出時間）
　　・すべての吐出口４６ａから吐出される吐出流量の合計
　　・洗浄液の温度
　　・洗浄液の種類（例えば、水、洗剤を含んだ水など） (Modification 7)
Although not specifically mentioned in the embodiment, the toilet seat back cleaning by the toilet seat back cleaning mechanism 42 may include a plurality of cleaning modes having different cleaning modes. For example, the toilet seat back cleaning by the toilet seat back cleaning mechanism 42 may include a plurality of cleaning modes in which at least one of the following is different.
・ Cleaning time (ie, cleaning liquid discharge time)
・ Total of discharge flow rate discharged from all discharge ports 46a ・ Temperature of cleaning liquid ・ Type of cleaning liquid (for example, water, water containing detergent, etc.)
　例えば、便座裏洗浄機構４２による便座裏洗浄には、第１洗浄モードと、第１洗浄モードよりも洗浄時間が長く、かつ、吐出流量が多い第２洗浄モードと、第２洗浄モードよりも洗浄時間が長く、かつ、洗浄液の温度が高い第３洗浄モードがあってもよい。 For example, in the toilet seat back cleaning by the toilet seat back cleaning mechanism 42, cleaning is performed in the first cleaning mode, the second cleaning mode in which the cleaning time is longer than that in the first cleaning mode, and the discharge flow rate is large, and in the second cleaning mode. There may be a third cleaning mode in which the time is long and the temperature of the cleaning liquid is high.
　なお、吐出流量の合計は、各吐出口４６ａからの吐出流量を増減させることで調整されてもよいし、吐出する吐出口４６ａの数を増減させることで調整されてもよい。 The total discharge flow rate may be adjusted by increasing or decreasing the discharge flow rate from each discharge port 46a, or may be adjusted by increasing or decreasing the number of discharge ports 46a to be discharged.
　複数の洗浄モードは、例えば以下のいずれか、または、これらの組み合わせによって使い分けられてもよい。
　　・予め決められたスケジュール
　　・前回の便座裏洗浄後の便器装置１０の使用回数
　　・ユーザが小便したか大便したか
　　・リモートコントロール装置８に対する操作 The plurality of cleaning modes may be selectively used, for example, by any of the following or a combination thereof.
-Pre-determined schedule-Number of times the toilet device 10 has been used after the last toilet seat cleaning-Whether the user has pissed or stooled-Operation on the remote control device 8
　例えば、動作制御部７４は、便器装置１０が使用されるごとに、第１洗浄モードで便座裏洗浄を実行し、１日に１回、決められた時刻に、第２洗浄モードで便座裏洗浄を実行し、１週間に１回、決められた時刻に、第３洗浄モードで便座裏洗浄を実行してもよい。 For example, every time the toilet device 10 is used, the operation control unit 74 performs toilet seat back cleaning in the first cleaning mode, and once a day, the toilet seat back cleaning is performed in the second cleaning mode at a predetermined time. And the toilet seat back cleaning may be performed once a week at a predetermined time in the third cleaning mode.
　また例えば、動作制御部７４は、前回の便座裏洗浄後の便器装置１０の使用回数が１０回に到達すると、第１洗浄モードで便座裏洗浄を実行し、当該使用回数が３０回に到達すると、第２洗浄モードを実行してもよい。 Further, for example, when the number of uses of the toilet device 10 after the previous toilet seat back cleaning reaches 10 times, the operation control unit 74 performs toilet seat back cleaning in the first cleaning mode, and when the number of uses reaches 30 times. The second cleaning mode may be executed.
　また例えば、動作制御部７４は、小便後は、第１洗浄モードで便座裏洗浄を実行し、大便後は、第２洗浄モードを実行してもよい。なお、動作制御部７４は、ユーザが小便したか、大便したかを、例えばユーザが便座２２に着座していた時間、すなわち接触検知センサ５４が検知していた時間に基づいて判断してもよい。 Further, for example, the operation control unit 74 may perform the toilet seat back cleaning in the first cleaning mode after the urination and the second cleaning mode after the stool. Note that the operation control unit 74 may determine whether the user has urinated or stool based on, for example, the time that the user has been sitting on the toilet seat 22, that is, the time that the contact detection sensor 54 has detected. .
　また、リモートコントロール装置８において実行する洗浄モードを選択でき、動作制御部７４は、リモートコントロール装置で便座裏洗浄の開始操作がなされると、選択された洗浄モードで便座裏洗浄を実行してもよい。 In addition, the cleaning mode to be executed in the remote control device 8 can be selected, and the operation control unit 74 can execute the toilet seat back cleaning in the selected cleaning mode when the toilet control is started with the remote control device. Good.
（変形例８）
　実施の形態では、制御部７０による制御（すなわち電気的な制御）により、便座２２が非閉状態では便座裏洗浄が実行されない場合について説明したが、機械的にこれが実現されてもよい。具体的には、例えば開閉弁５０が機械式の弁であり、便座２２が非閉状態になるとそれに連動して機械的に開閉弁５０が閉じられるように構成されてもよい。 (Modification 8)
In the embodiment, the case where the toilet seat back cleaning is not executed when the toilet seat 22 is in the non-closed state by the control by the control unit 70 (that is, electrical control) has been described, but this may be realized mechanically.
