　特開平１１－２０８３５９号公報は従来の移動式トイレを開示している。この移動式トイレは、トレーラ等の荷箱として構成されている。この移動式トイレは、機械室、及びトイレ室を備えている。機械室には、発電機や送風ポンプ等が収納されている。トイレ室には、大便器や小便器が各々複数配置されている。 Japanese Patent Application Laid-Open No. 11-208359 discloses a conventional mobile toilet. This mobile toilet is configured as a packing box for a trailer or the like. This mobile toilet is equipped with a machine room and a toilet room. A generator, a blower pump, etc. are housed in the machine room. A plurality of toilet bowls and urinals are arranged in the toilet room.
　特開平１１－２０８３５９号公報は従来の移動式トイレを開示している。この移動式トイレは、便器からの排水を浄化槽で浄化して便器に対して給水する循環システムを利用している。 Japanese Patent Application Laid-Open No. 11-208359 discloses a conventional mobile toilet. This mobile toilet uses a circulation system that purifies the wastewater from the toilet bowl with a septic tank and supplies water to the toilet bowl.
　この従来の移動式トイレでは、車いすの利用者がトイレ室に入室しやすいように、トイレ室の床面が低いことが望まれている。しかしながら、タイヤを避けてトイレ室の床面を低くする場合、タイヤを避けた部分の周囲がデッドスペースになってしまう。そのため、トイレ室の使い勝手が悪くなってしまう。 In this conventional mobile toilet, it is desired that the floor of the toilet room is low so that wheelchair users can easily enter the toilet room. However, when the floor surface of the toilet room is lowered by avoiding the tires, the area around the portion avoiding the tires becomes a dead space. Therefore, the usability of the toilet room deteriorates.
　第１の移動式トイレは、上記従来の実情に鑑みてなされたものであって、トイレ室の床が低く、トイレ室のスペースを有効に利用した使い勝手の良い移動式トイレを提供することを解決すべき課題としている。 The first mobile toilet was made in view of the above-mentioned conventional situation, and solved the problem of providing an easy-to-use mobile toilet that effectively utilizes the space of the toilet room because the floor of the toilet room is low. It is an issue that should be done.
　この従来のものは前室がないため、トイレを使用した使用者がくつろぐことができない。特に、このトイレを車いす利用者が使用することを考慮すると、トイレ室に入る前後において待機する場所としての前室がないため、使い勝手がよくない。 This conventional one does not have an anterior room, so users who use the toilet cannot relax. In particular, considering that this toilet is used by wheelchair users, it is not convenient because there is no front room as a place to wait before and after entering the toilet room.
　第２の移動式トイレは、上記従来の実情に鑑みてなされたものであって、使い勝手のよい移動式トイレを提供することを解決すべき課題としている。 The second mobile toilet was made in view of the above-mentioned conventional situation, and it is an issue to be solved to provide a mobile toilet that is easy to use.
　この従来の移動式トイレは、便器からの排水を浄化して便器へ給水する循環システムを利用するため、浄化槽等を設置するためのスペースが嵩みがちである。これによって、この移動式トイレは、トイレ室として利用することができるスペースが小さくなってしまい、車いす利用者にとって利用し難いものになるおそれがある。このため、便器に供給する清水を貯留する給水タンクと、便器からの汚水を貯留する排水タンクを利用することによって、給排水システムを簡易化して、トイレ室として利用することができるスペースを大きくすることが考えられる。この場合、給水タンク及び排水タンクは、清水や汚水を貯留すると重くなり、それぞれのタンクに貯留する清水及び汚水の量が増減するため、給水タンク及び排水タンクを配置する位置によっては車両が傾くおそれがある。特に、車両が左右方向に傾いていると、車両の移動の妨げになるおそれがある。このため、左右方向の重量バランスを考慮した給水タンク及び排水タンクの配置が重要である。 Since this conventional mobile toilet uses a circulation system that purifies the wastewater from the toilet bowl and supplies it to the toilet bowl, the space for installing a septic tank or the like tends to be bulky. As a result, the space that can be used as a toilet room of this mobile toilet becomes small, which may make it difficult for wheelchair users to use it. Therefore, by using a water supply tank that stores fresh water supplied to the toilet bowl and a drainage tank that stores sewage from the toilet bowl, the water supply and drainage system should be simplified and the space that can be used as a toilet room should be increased. Can be considered. In this case, the water supply tank and drainage tank become heavy when fresh water and sewage are stored, and the amount of fresh water and sewage stored in each tank increases or decreases. Therefore, the vehicle may tilt depending on the position where the water supply tank and drainage tank are arranged. There is. In particular, if the vehicle is tilted to the left or right, it may hinder the movement of the vehicle. Therefore, it is important to arrange the water supply tank and the drainage tank in consideration of the weight balance in the left-right direction.
　第３の移動式トイレは、上記従来の実情に鑑みてなされたものであって、車両の左右バランスを良好に保つことができる移動式トイレを提供することを解決すべき課題としている。 The third mobile toilet was made in view of the above-mentioned conventional situation, and it is an issue to be solved to provide a mobile toilet that can maintain a good left-right balance of the vehicle.

A toilet paper holder 27 and a fixed handrail 28 are attached to the front surface of the first cabinet 20A located below the handwasher 26. The front surface of the first cabinet 20A referred to here is a surface facing left in the first cabinet 20A. A trash can D is provided below the toilet paper holder 27 in the first cabinet 20A. The wash basin 29 is provided at a position away from the toilet bowl 22 of the first cabinet 20A (that is, behind the toilet room 20).
　各衛生器具２１，２２，２６，２９は、図示しない操作部を使用者が操作することによって給水タンク１２から清水が供給される。操作部は、汚物流し２１や便器２２においては、押しボタンの形態であり、手洗器２６や洗面器２９においては、使用者の手などの物体を検知するセンサの形態である。各操作部は、操作されたり、使用者の手などの物体の接近を検知したりすると、制御部に対して吐水信号を出力する。 For each sanitary fixture 21, 22, 26, 29, fresh water is supplied from the water supply tank 12 by the user operating an operation unit (not shown). The operation unit is in the form of a push button in the sewage distribution 21 and the toilet bowl 22, and in the form of a sensor that detects an object such as a user's hand in the hand wash basin 26 and the wash basin 29. Each operation unit outputs a water discharge signal to the control unit when it is operated or detects the approach of an object such as a user's hand.
　便器２２を洗浄する場合、操作部が操作されると、便器２２に設けられた開閉弁が開弁する。操作部の操作に伴って、操作部から出力した吐水信号が制御部に入力され、制御部によって給水ポンプ１４の動作が開始する。給水ポンプ１４が動作すると、給水タンク１２から清水が給水路１４Ａを介して便器２２に流入する。便器２２に流入した清水は、便器２２を洗浄した後、第２搬送装置２０Ｊに汚水として流入する。制御部は、第２搬送装置２０Ｊに流入した汚水が所定量になると、ポンプ機能を駆動し、汚水が排水路１３Ａを介して排水タンク１３に流入し、貯留する。制御部は、第２搬送装置２０Ｊの内部の汚水が排出されると、第２搬送装置２０Ｊのポンプ機能を停止する。操作部の操作後、所定の時間が経過すると、便器２２の開閉弁が閉弁するとともに、制御部によって給水ポンプ１４の動作が停止する。このようにして、便器２２の洗浄が終了する。汚物流し２１を洗浄する場合、給水ポンプ１４及び第１搬送装置２０Ｈは同様に駆動し、洗浄が行われる。汚物流し２１に設けられた操作ハンドルを操作して開閉弁を開弁すると、制御部によって給水ポンプ１４が動作し、操作ハンドルを操作して開閉弁を閉弁すると、制御部によって給水ポンプ１４が停止する。このようにして、汚物流しの吐水部から清水が吐水される。 When cleaning the toilet bowl 22, when the operation unit is operated, the on-off valve provided in the toilet bowl 22 opens. Along with the operation of the operation unit, the water discharge signal output from the operation unit is input to the control unit, and the control unit starts the operation of the water supply pump 14. When the water supply pump 14 operates, fresh water flows from the water supply tank 12 into the toilet bowl 22 via the water supply channel 14A. The fresh water that has flowed into the toilet bowl 22 flows into the second transport device 20J as sewage after cleaning the toilet bowl 22. When the amount of sewage flowing into the second transport device 20J reaches a predetermined amount, the control unit drives the pump function, and the sewage flows into the drainage tank 13 via the drainage channel 13A and stores the sewage. When the sewage inside the second transport device 20J is discharged, the control unit stops the pump function of the second transport device 20J. When a predetermined time elapses after the operation of the operation unit, the on-off valve of the toilet bowl 22 is closed and the operation of the water supply pump 14 is stopped by the control unit. In this way, the cleaning of the toilet bowl 22 is completed. When cleaning the sewage 21, the water supply pump 14 and the first transport device 20H are driven in the same manner to perform cleaning. When the operation handle provided on the 21 is operated to open the on-off valve, the water supply pump 14 is operated by the control unit, and when the operation handle is operated to close the on-off valve, the water supply pump 14 is operated by the control unit. Stop. In this way, fresh water is discharged from the water discharge section of the waste distribution.
　手洗器２６及び洗面器２９を使用する場合、使用者の手などをセンサが検知している間、手洗器２６及び洗面器２９に設けられた開閉弁が開弁し、使用者の手などをセンサが検知しなくなると、手洗器２６及び洗面器２９に設けられた開閉弁は閉弁する。センサが使用者の手などを検知している間、操作部から吐水信号が制御部に入力し続け、制御部によって給水ポンプ１４の動作が継続する。このようにして、手洗器２６及び洗面器２９に設けられた吐水部から清水が吐水される。手洗器２６及び洗面器２９から流出した汚水は、第２搬送装置２０Ｊによって、排水路１３Ａを介して排水タンク１３に流入し、貯留される。制御部は、上述したように、第２搬送装置２０Ｊに流入した汚水が所定量になると、ポンプ機能を駆動し、第２搬送装置２０Ｊの内部の汚水が排出されると第２搬送装置２０Ｊのポンプ機能を停止する。 When using the hand wash basin 26 and the wash basin 29, the on-off valve provided in the hand wash basin 26 and the wash basin 29 opens while the sensor detects the user's hand and the like, and the user's hand and the like are opened. When the sensor stops detecting, the on-off valves provided in the hand wash basin 26 and the wash basin 29 are closed. While the sensor detects the user's hand or the like, a water discharge signal from the operation unit continues to be input to the control unit, and the control unit continues the operation of the water supply pump 14. In this way, fresh water is discharged from the water discharge portions provided in the hand wash basin 26 and the wash basin 29. The sewage flowing out from the hand wash basin 26 and the wash basin 29 flows into the drainage tank 13 through the drainage channel 13A by the second transport device 20J and is stored. As described above, the control unit drives the pump function when the amount of sewage flowing into the second transport device 20J reaches a predetermined amount, and when the sewage inside the second transport device 20J is discharged, the control unit of the second transport device 20J Stop the pump function.
