  By the way, when installing a flushing and feeding mobile toilet in a hospital or an elderly facility, etc., it is frequently moved between hospital rooms according to the demands of the elderly and the sick. Each hospital room may be on the same floor or on different floors, and the drainage environment varies depending on the installation environment.Therefore, malfunctions and errors may occur in drainage control based on a single preset drainage efficiency value. Judgment may occur frequently. In particular, when installing such flush-pumping mobile toilets, there are many cases where the drainage environment that was not present at the time of building is prepared afterwards, and the variation in drainage capacity becomes significant. Expected to occur more frequently.

  For example, if it is installed in a hospital room with very poor drainage efficiency, the drainage time will be long, so it may be judged that a problem such as clogging of filth has occurred and it may be determined that the drainage is abnormal. . In order to avoid such an erroneous determination, it is necessary to set a long drainage time for determining that a malfunction has occurred, or to set a low drainage flow rate for determining that a malfunction has occurred. However, if the drainage abnormality determination threshold is raised in this way, the drainage time is not determined and the drainage time remains long, and in an extreme case, there is a possibility of overflow.

  Therefore, in the present invention, even when the apparatus is installed by moving between different locations of the drainage environment, it is possible to perform control suitable for each drainage environment, and the water washing that can perform the drainage abnormality determination without error. An object is to provide a pumping mobile toilet.

  In order to solve the above-mentioned problems, a flush-feed mobile toilet according to the present invention is connected to a toilet main body, and the toilet main body through a water supply hose and a drain hose, and is attached to and detached from a fixed-side water supply / drain joint provided in the building. A movable-side water supply / drainage joint that is freely connected, a pumping device that is connected to a drainage port of the toilet body through a shut-off valve, and that pumps sewage through the drainage hose, and a water supply device that supplies water to the toilet body And a water level detecting means for detecting the water level in the pressure feeding device, and a control means for controlling the pressure feeding device and the water supply device, wherein the control means comprises: The drainage state measuring means for measuring the drainage state during the operation of the pumping device and obtaining the drainage state measurement value, the drainage abnormality determination threshold stored in advance, and the drainage abnormality processing for executing the drainage abnormality processing when the drainage abnormality is determined. An abnormality processing means, and the drainage abnormality processing means is executed when the drainage state measurement value falls below the drainage abnormality threshold, and the control means further measures the drainage environment to measure the drainage environment. Threshold value setting means for acquiring a measurement value, calculating a drainage abnormality determination threshold value based on the drainage environment measurement value, and storing it as a reference value is provided.

  In the present invention, since the drainage environment is measured and the drainage environment measurement value is acquired, even if the drainage environment in which the flushing / pumping movable toilet is changed, the drainage environment measurement value corresponding to the changed drainage environment is acquired. can do. As described above, the drainage abnormality determination threshold value is calculated based on the drainage environment measurement value acquired according to the drainage environment and stored as a reference value.For example, the room moves between rooms or the rooms are located on different floors. Even if it does, the waste water abnormality process based on the reference value according to the waste water environment can be performed. Therefore, even in a hospital or the like where the drainage environment differs from place to place, it is possible to install a flush-pumped mobile toilet in a place where it is desired to be installed, and to provide a highly convenient flush-pumped mobile toilet.

  Moreover, in the flushing and pumping mobile toilet according to claim 2, the drainage abnormality processing means when the control means falls below the drainage abnormality determination threshold stored in advance a plurality of times the drainage state measurement value is continuously reduced. It is characterized by performing.

  The flushing and feeding mobile toilet according to the present invention is moved between rooms, and the rooms may be on the same floor or on different floors. Thus, in order to improve portability, the water supply / drainage hose cannot be made so large, and in such a thin water supply / drainage hose, the drainage environment greatly fluctuates depending on the bent state or the like, and there is a possibility that an instantaneous drainage failure may occur. In addition, even when the water supply / drainage hose is in a normal state, it is assumed that filth is caught instantaneously, resulting in an instantaneous drainage failure state. In consideration of such circumstances, it is considered that even if the drainage failure state is not truly true, the drainage state measurement value may instantaneously fall below the drainage abnormality determination threshold. Therefore, in this aspect, the drainage abnormality determination threshold is set to the accidental situation as described above by executing the drainage abnormality processing means when the drainage state measurement value is continuously lower than the stored drainage abnormality determination threshold value a plurality of times. It is assumed that it can be set to an appropriate value without considering.

  Further, in the flushing and feeding mobile toilet according to claim 3 of the present application, even if the control means is a case where the drainage state measurement value falls below the drainage abnormality determination threshold stored in advance, the operation of the pumping device is controlled. The drainage process is terminated by continuously executing the drainage abnormality processing means when the drainage state measurement value falls below the drainage abnormality determination threshold value continuously in a plurality of continuous drainage processes. It is characterized by doing.

  As described above, the flushing / pumping mobile toilet according to the present invention may accidentally cause the drainage state measurement value to instantaneously fall below the drainage abnormality determination threshold even if the drainage is not truly in a poor drainage state. it is conceivable that. Therefore, in this aspect, even when the drainage state measurement value falls below the stored drainage abnormality determination threshold, the drainage process is terminated by continuing the operation of the pumping device, thereby instantaneously clogging filth. Draining can be continued to eliminate the problem. In addition, when the drainage condition measurement value falls below the drainage abnormality determination threshold value continuously in a plurality of continuous drainage processes, the wastewater abnormality treatment means is executed, so that true waste that cannot be removed by continuing drainage. Clogging can be detected, and more reliable operation can be ensured.

  Further, in the flush toilet pump according to claim 4 of the present application, the control unit includes a threshold measurement start unit, and supplies water into the pumping device based on a signal output from the threshold measurement start unit. The drainage environment measurement value is acquired by measuring the drainage state by discharging the water, and the drainage abnormality determination threshold is stored as a reference value based on the acquired drainage environment measurement value.

  In this aspect, since the threshold measurement start means is provided, the drainage environment measurement value can be measured at the timing when it is desired to be measured. Also, water is fed into the pumping device based on the signal output from the threshold measurement starting means, and the drainage environment is measured by discharging the supplied water to obtain the drainage environment measurement value. It is possible to measure the drainage environment measurement value, and it is possible to perform measurement in a state where no solid matter flows, and the drainage environment measurement value can be obtained more accurately.

  Further, in the flush toilet pump according to claim 5 of the present application, the threshold measurement start means is executed when a commercial power supply is turned on to the control means, and the control means shifts to a normal use state after completion of the execution. It is characterized by doing.

Can be acquired.

  Further, in the flushing and pumping mobile toilet according to claim 6 of the present application, the control means is configured to be able to store a plurality of the drainage abnormality determination threshold values independently, and from among the plurality of stored drainage abnormality determination threshold values. It is characterized by being able to select any one.

  In this aspect, since a plurality of drainage abnormality determination threshold values can be stored independently, for example, the drainage abnormality determination threshold value can be stored for each different room or each different floor, and the flush flushing mobile toilet is separated. Even if it moves to this place, the setting which measures a drainage environment measurement value each time and acquires a drainage abnormality determination threshold value becomes unnecessary. Moreover, since the drainage abnormality determination threshold value for each place can be stored, it is possible to grasp the secular change of the drainage environment in each place.

  Further, in the flush flushing mobile toilet according to claim 7 of the present application, the moving side water supply / drainage joint is provided with joint identifying means for identifying the fixed side water supply / drainage joint, and the drainage abnormality determination is made when connected to the fixed side water supply / drainage joint. The threshold value is automatically selected and adopted.

  Further, in the flushing and pumping mobile toilet according to claim 8 of the present application, the drainage environment measurement value is a value obtained by measuring the flow rate of drainage due to the operation of the pumping device, and the drainage abnormality determination threshold is the drainage environment measurement value. It is determined as a value obtained by subtracting from a value to a predetermined ratio, and the ratio is configured to vary according to a predetermined condition.

  In this aspect, the drainage abnormality determination threshold is determined as a value reduced from the drainage environment measurement value to a predetermined ratio, and the ratio is configured to vary according to a predetermined condition. The ratio can be changed according to the magnitude of the drainage environment measurement value, and a drainage abnormality determination threshold value can be set according to the drainage state of the installation site.

  Further, in the flushing / pumping mobile toilet according to claim 9 of the present application, the ratio is configured to increase as the drainage environment measurement value decreases.

  In the case of the present invention, when the drainage environment measurement value is small, the drainage capacity is reduced, so it becomes a momentary clogging state with a slight fluctuation factor, and there is actually no problem. May also be judged as an abnormal drainage. Therefore, in this aspect, when the drainage environment measurement value is small, by increasing the drainage abnormality determination threshold, it is possible to relax the condition that causes drainage abnormality and avoid erroneous determination due to instantaneous clogging of filth, By flowing drainage, instantaneous clogging can be eliminated, and the transition to abnormal operation can be suppressed.

  Further, in the flush-pumped mobile toilet according to claim 10 of the present application, the ratio is configured to increase as the time during which the flush-pumped mobile toilet is used in the same environment becomes longer.

  When this flush-pumped mobile toilet is used in the same environment, the water pipes on the building side will gradually clog and become difficult to flow, the drainage environment measurement value will gradually decline, and there is a high possibility that it will be judged as drainage abnormality. It is assumed that Therefore, in this aspect, by increasing the drainage abnormality determination threshold as the time used in the same environment is longer, it is possible to relax the condition that causes drainage abnormality and avoid erroneous determination due to instantaneous clogging of filth. By flowing drainage, instantaneous clogging can be eliminated, and the transition to abnormal operation can be suppressed.

  Further, in the flush flushing mobile toilet according to claim 11, the second drainage abnormality threshold value is smaller than the drainage abnormality threshold value, and the second drainage abnormality threshold value is a fixed value that is not updated, and the control means. Is characterized in that, when the drainage state measurement value falls below the second drainage abnormality threshold value, the drainage abnormality processing means executes the second drainage abnormality process that is strictly regulated.

  In this aspect, since the second drainage abnormality threshold is smaller than the drainage abnormality threshold, the drainage abnormality determination based on the drainage abnormality threshold is specialized in the determination of temporary sudden drainage abnormality. The drainage abnormality determination based on the drainage abnormality can be a backup determination so as to determine a more serious drainage abnormality, and the drainage abnormality determination based on the drainage abnormality threshold can be relaxed so as not to be excessive.

  Further, in the flush toilet pump according to claim 12 of the present application, the control means is configured to execute the drainage abnormality processing means when the continuous drainage time of the pumping device is a predetermined time or more. To do.

  In this aspect, since the continuous drainage time of the pumping device is configured to execute the drainage abnormality processing means for a predetermined time or more, the pumping device is necessary even if the drainage abnormality determination based on the drainage abnormality threshold is not excessive. As described above, the continuous operation is not performed, and it is possible to solve the problems such as the occurrence of a failure and the excessive draining time.

  The amount of water supplied to the toilet main body 30 is adjusted by opening and closing the water supply valve 4c including an electromagnetic valve or the like by a control device 6 (control means).

  For example, the seating detection sensor (sitting state detection means) 301 of the toilet body 30 detects the seating of the user, or the user uses a water supply command provided on an operation panel (not shown in FIG. 4) of the remote controller. When the water supply switch (not shown) is turned on, the control device 6 controls the water supply device 4 on the basis of detection information from these seating detection sensors (not shown) and instructions from the water supply switch (not shown). The water supply command is supplied to the toilet main body 30 for a predetermined time, and a predetermined amount of water is accumulated in the toilet main body 30. Furthermore, when the user turns on a cleaning switch (cleaning operation switch, not shown in FIG. 4) of the remote controller for cleaning the toilet body 30 after using the toilet, the water supply device 4 supplies water for cleaning to the toilet body 30. The toilet main body 30 is washed. The seating detection sensor 301 may be proximity detection means using infrared rays, microwaves, or the like, or actual seating detection means for detecting that the user is actually seated using an electrostatic sensor or the like.

  A pumping device 8 that is a solid material crushing pumping device is provided outside the toilet body 30, and the pumping device 8 includes a storage tank 40 connected to the outlet 2 a of the toilet body 30. A flap valve 9 (shutoff valve) is provided at the discharge port 2a of the toilet body 30, and the flap valve 9 closes the discharge port 2a until the toilet bowl is cleaned. Further, the flap valve 9 opens the discharge port 2a for a predetermined time according to a command from the control device 6 when the toilet body 30 is washed and the sewage in the toilet body 30 is discharged to the storage tank 40. The sewage in the toilet body 30 is discharged and then closed.

  Further, in the storage tank 40, a pulverizing unit 42 for pulverizing solid matter 41 such as feces and toilet paper discharged from the outlet 2 a of the toilet body 30 to the storage tank 40, and a lower part of the pulverizing unit 42 Is provided with a pump 44 that forcibly pumps the sewage in the storage tank 40 to the outside.

  The crushing section 42 includes a crushing chamber 50 (crushing device) formed by a screen 48 having a plurality of holes 46. The sewage discharged from the outlet 2a of the toilet body 30 into the storage tank 40 is first crushed. The chamber 50 is once accommodated. As for the sewage in the pulverization chamber 50, the solid material 41 larger than the size of the hole 46 of the screen 48 cannot be passed through the hole 46 and is captured in the pulverization chamber 50, so Small solid matter flows through the holes 46 and flows from the crushing chamber 50 to the storage tank 40.

  Further, a cutter 52 (a pulverizing device) is provided in the pulverization chamber 50, and the solid material 41 captured in the pulverization chamber 50 is pulverized by the rotation of the cutter 52. An impeller 56 is attached to the lower end of the rotary shaft 54 of the cutter 52, and a crushing and pressure-feeding motor 58 (crusher) that drives the rotary shaft 54 so as to be able to rotate forward and backward is attached to the upper end of the rotary shaft 54. . The driving of the pulverizing and pressure-feeding motor 58 is variably controlled by the control device 6 based on the water level detected by a water level sensor 60 (water level detecting means, details will be described later) provided in the storage tank 40. The rotations of the cutter 52 and the impeller 56 are controlled in conjunction with each other.

  The pressure feed path 62 is provided with an electric ball valve 64 as a pressure feed suppressing means. This electric ball valve 64 opens and closes in response to a command from the control device 6 based on the water level information of the water level sensor 60, and in particular suppresses the amount of sewage pumped from the pump 44 during pulverization, thereby reducing the water level in the storage tank 40. The reduction is suppressed.

  Moreover, about the water supply apparatus 4 mentioned above, the crushing part water supply path 4b which supplies additional water to the crushing part 42 is provided, This water supply apparatus 4 and the crushing part water supply path 4b are control apparatuses based on the water level information of the water level sensor 60. 6, the water supply valve 4 d is opened, and additional water is supplied to the crushing unit 42 so that the water level of the crushing unit 42 is always higher than the water level at the upper end of the cutter 52 (the cutter upper end water level) when crushing solid matter. ing.

  In the flushing and feeding mobile toilet 10 of this embodiment, instead of providing the crushing part water supply path 4b in the water supply apparatus 4 described above, an additional water supply apparatus (not shown) that is separate from the water supply apparatus 4 is provided independently. Even when the toilet main body 30 is in use, additional water may be supplied to the crushing unit 42 from an additional water supply device (not shown). Moreover, about the water supply opening (not shown) to the grinding | pulverization part 42 of the crushing part water supply path 4b, the storage tank 40 is supplied from the water supply opening (not shown) of the crushing part water supply path 4b by devising the shape and arrangement | positioning. It may be possible to perform spray cleaning inside.

  Furthermore, the flushing and feeding mobile toilet 10 according to the present embodiment includes a crushing completion detection device 66, and the crushing completion detection device 66 detects that the crushing of the solid material 41 by the cutter 52 of the crushing unit 42 has been completed.

Specifically, the crushing completion detection device 66 detects the torque, rotational resistance, etc. of the crushing pressure feeding motor 58 or the cutter 52, and judges the crushing state based on the degree of these detected values, and according to the situation. The control device 6 controls the crushing pressure feed motor 58 and controls additional water supply from the crushing part water supply passage 4b to the crushing part 42.

  Next, details of the above-described water level sensor 60 provided in the storage tank 40 will be described. In the present embodiment, the water level in the storage tank 40 detected by the water level sensor 60 is stored in consideration of the amount of drainage discharged from the toilet body 30 by one washing, the drainage capacity of the pump 44, the capacity of the storage tank 40, and the like. From the lower side of the tank 40, there are five specific water levels: a pump operation stop water level L1, a sealed water standby water level L2, a pump operation start water level (standby allowable water level) L3, a toilet use allowable water level L4, and a first allowable limit water level L5. Is set. After the toilet main body 30 is washed, sewage is discharged into the storage tank 40, the water level in the storage tank 40 rises, and the water level detected by the water level sensor 60 reaches the pump operation start water level L3. The operation of the pump 44 is started together with the motor 58. When the pump 44 is driven for a predetermined time to lower the water level and the water level detected by the water level sensor 60 reaches the pump operation stop water level L1, the operation of the pump 44 is stopped together with the crushing and pressure feeding motor 58. Yes.

  Furthermore, the first allowable limit water level L5 described above is set above the pump operation start water level L3 and the toilet use allowable water level L4, and is set lower than the water level at which the storage tank 40 is full. The first permissible limit water level L5 is a water level that cannot be reached under normal operation of the flush pumping mobile toilet 10, but due to troubles in the drainage system such as clogging of the piping of the pumping path 62 and malfunction of the pump 44, When the water level in the storage tank 40 rises abnormally, the water level sensor 60 detects an abnormality at the first allowable limit water level L5.

  Here, the water level sensor 60 used in the present embodiment is preferably a pressure-sensitive water level sensor using a hollow tube 60a. In the pressure-sensitive water level sensor 60, when the opening lower end portion 60b of the hollow tube 60a is submerged, the air in the hollow tube 60a flows into the water surface of the lower opening portion 60b and the pressure sensitive portion 60c provided at the upper end of the hollow tube 60a. Thus, the airtight state is established, and the pressure sensing unit 60c senses the water pressure through the air in the hollow tube 60a. A considerable water level in the storage tank 40 is output according to the water pressure sensed by the pressure sensing unit 60c, and the water level can be sensed pressure-sensitively without contact.

  Further, since the water level cannot be measured when the water level in the storage tank 40 falls below the water level of the opening lower end 60b, the distance h between the bottom surface in the storage tank 40 and the opening lower end 60b is made as small as possible to lower the opening lower end. Although it is preferable to set 60b to a low position, it is preferable to set the distance h to 10 mm or more so that dirt is not caught between the bottom surface in the storage tank 40 and the opening lower end 60b.

  On the other hand, about the diameter D of the opening lower end part 60b, about 20 mm is preferable since it is empirically known that it does not close if it has a dimension of about 20 mm. Moreover, the diameter dimension about parts other than the opening lower end part 60b may be set smaller than 20 mm, and the capacity | capacitance in the storage tank 40 may be saved.

  Further, an emergency limit sensor 61 is provided in the vicinity of the water level sensor 60, and this limit sensor 61 has a water level slightly higher than the first allowable limit water level L5 described above, separately from the water level sensor 60. The second allowable limit water level L6 can be detected. The limit sensor 61 can detect an abnormality at the second allowable limit water level L6 even when the first allowable limit water level L5 cannot be detected due to a malfunction of the water level sensor 60.

  Here, as the limit sensor 61 used in the present embodiment, an electrode type sensor is preferable. The electrode type limit sensor 61 detects the water level based on a resistance change between the electrodes 61a and 61b when water is immersed between the electrodes 61a and 61b. In addition, a cylindrical shield 61c is provided around the electrodes 61a and 61b. By this shield 61c, filth scattered from the holes 46 of the screen 48 of the crushing portion 42 directly hits the electrodes 61a and 61b. It is supposed not to. Since the shield 61c has a bottomless and cylindrical shape, when the water level in the storage tank 40 rises, the shield 61c can be detected by the electrodes 61a and 61b without blocking the water. .

  Further, as the limit sensor 61, in addition to the electrode type sensor described above, a pressure-sensitive sensor similar to the above-described water level sensor 60 can be applied, but the same type of sensor is used for the water level sensor 60 and the limit sensor 61. Therefore, it is also preferable to use a sensor of a different type from the pressure-sensitive sensor, such as a diaphragm sensor, an electrostatic sensor, or a float sensor.

  In this embodiment, an example is described in which a pressure-sensitive sensor is used as the water level sensor 60, but other types of sensors such as an ultrasonic sensor may be used in addition to this sensor. For example, a mode in which the pressure is detected by the potential and the water level is calculated by the control device 6 is also preferable.

  Further, an abnormality indicator 63 is connected to the control device 6. When the water level sensor 60 detects the first permissible limit water level L5 or the limit sensor 61 detects the second permissible limit water level L6, the control device 6 detects that an abnormal situation such as a drainage system or water supply system trouble is a water-washing pressure transfer type. It is determined that the toilet 10 has occurred, warnings about abnormalities such as various troubles are displayed on the abnormality indicator 63, and the water supply valves 4c and 4d are closed so that the water supply cannot be performed so that the water supply device 4 is not operated. It has become.

  Further, the control device 6 operates when the water level sensor 60 or the limit sensor 61 has not decreased to a predetermined water level after the pump 44 has been operated for a predetermined time, or when the water level sensor 60 has the first allowable limit water level. When L5 is detected and the limit sensor 61 detects the second allowable limit water level L6, the abnormality indicator 63 displays the drainage abnormality.

  Furthermore, after operating the water supply device 4 for a predetermined time, the control device 6 displays a water supply abnormality on the abnormality indicator 63 when the water level detected by the water level sensor 60 is less than the predetermined water level. .

  Further, when the water level sensor 60 does not detect the first allowable limit water level L5 and the limit sensor 61 detects the second allowable limit water level L6, the control device 6 displays an abnormality in the water level sensor 60 on the abnormality indicator 63. Is displayed. The abnormality indicator 63 is also configured to notify notification information to be notified to other users, and details thereof will be described later.

  The flush toilet mobile toilet 10 of the present embodiment is provided with a hand-washer 70 as another watering device. The hand-washer 70 is provided with a water supply pipe 71 and a drain pipe 72. The water supply pipe 71 is connected to a water supply path 4e for a hand-washer provided in the water supply device 4 via a joint 71a. The drainage pipe 72 is connected to a handwasher drainage channel 67 provided in the storage tank 40 via a joint 72b. The hand wash basin drain 67 is provided with a check valve 67a that functions in the same manner as the backflow prevention means and the drain trap, and is configured to prevent sewage and off-flavors from flowing back from the storage tank 40. The water supply pipe 71 may be connected to a pipe branched directly from the water supply hose SH without going through the water supply apparatus 4.

  Next, the functional configuration of the control device 6 will be described with reference to the block diagram shown in FIG. As shown in FIG. 5, the control device 6 includes a CPU 80, a memory 81, an operation receiving unit 800 as an interface, a water level detection unit 801, a limit detection unit 802, a seating detection unit 803, a joint identification unit 804, and a motor drive unit. 805, a water supply valve drive unit 806, a drain valve drive unit 807, a display unit 808, and a pressure feed suppression unit 809.

  The operation receiving unit 800 is a part that outputs an operation signal input from the operation panel 82 to the CPU 80. The water level detection unit 801 is a part that outputs a water level signal output from the water level sensor 60 to the CPU 80. The limit detection unit 802 is a part that outputs a limit water level signal output from the limit sensor 61 to the CPU 80. The seating detection unit 803 is a part that outputs a seating signal output from the seating detection sensor 301 to the CPU 80. The joint identifying unit 804 is a part that outputs, to the CPU 80, an identification signal for identifying a building-side water / drain joint that is output from the joint sensor 15s provided in the water supply hose SH and the drain hose DH. The motor driving unit 805 is a part that outputs a motor driving signal to the crushing and pressure feeding motor 58 based on a control signal output from the CPU 80. The water supply valve drive unit 806 is a part that outputs a water supply valve drive signal to the water supply valves 4 c and 4 d based on a control signal output from the CPU 80. The drain valve driving unit 807 is a part that outputs a drain valve driving signal to the flap valve 9 based on a control signal output from the CPU 80. The display unit 808 is a part that outputs a display signal for performing a drainage abnormality notification or a provisional operation notification to the abnormality indicator 63 based on a control signal output from the CPU 80. The pressure suppression unit 809 is a part that outputs a ball valve drive signal to the electric ball valve 64 based on a control signal output from the CPU 80.

  The CPU 80 receives signals output from the operation reception unit 800, the water level detection unit 801, the limit detection unit 802, the seating detection unit 803, and the joint identification unit 804, performs predetermined information processing, and the result of the information processing A control signal corresponding to the control to be executed is output to each of the motor drive unit 805, the water supply valve drive unit 806, the drain valve drive unit 807, the display unit 808, and the pressure feed suppression unit 809. As a result, the CPU 80 functions as a drainage state measurement unit, a drainage abnormality processing unit, a threshold setting unit, a threshold measurement start unit, a selection support unit, and a selection unit. The control device 6 configured as described above can perform various controls in accordance with the characteristics in which the flush washing / moving toilet 10 is used and the characteristics in which it is used.

  First, the control device 6 measures the drainage state during the operation of the pumping device 8, and obtains the drainage state measurement value, the drainage abnormality determination threshold stored in advance, and the drainage abnormality processing when the drainage abnormality is determined. A wastewater abnormality treatment means to be executed, and when the wastewater state measurement value falls below a wastewater abnormality threshold value, the wastewater abnormality treatment means is executed, and the wastewater environment is measured to obtain a wastewater environment measurement value, It functions as comprising a threshold value setting means for calculating a drainage abnormality determination threshold value based on the acquired drainage environment measurement value and storing it as a reference value.

  In this aspect, the flushing / pumping mobile toilet 10 equipped with the control device 6 measures the drainage environment and obtains the drainage environment measurement value. Therefore, even if the drainage environment in which the flushing / pumping mobile toilet 10 is installed varies. The drainage environment measurement value according to the changed drainage environment can be acquired. As described above, the drainage abnormality determination threshold value is calculated based on the drainage environment measurement value acquired according to the drainage environment and stored as a reference value.For example, the room moves between rooms or the rooms are located on different floors. Even if it does, the waste water abnormality process based on the reference value according to the waste water environment can be performed. Therefore, even in a hospital or the like where the drainage environment differs from place to place, the flushing / pumping mobile toilet 10 can be installed at a place where it is desired to be installed, and the flushing / pumping mobile toilet 10 that is very easy to use can be provided. .

  Further, the control device 6 executes drainage abnormality processing when it is determined that there is a drainage abnormality based on a drainage state measurement unit that measures the drainage state during operation of the pumping device 8 and a signal output from the drainage state measurement unit. A waste water abnormality processing means, and the waste water abnormality processing means is a temporary abnormality operation means for performing a predetermined operation during a predetermined period when it is determined that the waste water abnormality has occurred, and a waste water abnormality notifying that there is a waste water abnormality. It functions as having abnormality processing execution means for executing notification.

  In this aspect, the flushing / moving toilet 10 equipped with the control device 6 can flexibly respond to changes in the installed drainage environment. Specifically, the flushing / pumping mobile toilet 10 is moved between rooms, and the rooms may be on the same floor or on different floors. Thus, in order to improve portability, the water supply hose SH and the drainage hose DH cannot be increased so much. In such a thin water supply hose SH and the drainage hose DH, the drainage environment greatly varies depending on the bent state, etc. There is a risk of poor drainage. In addition, even when the water supply hose SH and the drainage hose DH are in a normal state, it is assumed that the filth is caught instantaneously, resulting in a temporary poor drainage state. Considering such circumstances, even if the drainage is not truly in a poor state, it is considered that the drainage abnormality may occur accidentally. Therefore, in order to eliminate such a temporary drainage failure state, by having provisional abnormal operation means, it becomes possible to perform a predetermined operation during a predetermined period determined as drainage abnormality, and the predetermined operation Is configured to eliminate the poor drainage state. Accordingly, it is possible to avoid excessive drainage abnormality determination while relaxing the threshold value for determining drainage abnormality and avoiding the true clogging of filth. Furthermore, by having an abnormality processing execution means, at least a drainage abnormality notification for notifying that the user has a sense of incongruity with the operation of the temporary abnormal operation means that is not an original operation is executed. Is possible.

  Further, the control device 6 performs control so as to constitute sealed water by storing water in the pressure feeding device 8 without storing water in the toilet body 30 during use standby. Further, the control device 6 performs the seating determination and the seating determination based on the signal output from the seating detection unit, and when the seating determination determines that the user is seated on the toilet body 30, the water supply to the toilet body 30 is performed. When the seating determination determines that the user is seated and then stool, the seat body 30 is controlled so as to drain the pooled water. There are at least two seating determination values for determination and separation determination as the first seating determination value and the second seating determination value, and the first seating determination value and the second seating determination value are respectively continuous seating serving as a determination criterion. The first seating determination value corresponding to the short continuous seating time is used for the seating determination, and the second seating determination value corresponding to the long continuous seating time is used for the seating determination. .

  The control device 6 performs the seating determination and the seating determination because it is difficult for a user who is assumed to use the flushing / feeding mobile toilet 10 to prepare for actual stool. This is because the seating and the seating on the main body 30 are repeated many times. When the control device 6 performs such seating determination and seating determination, if toilet water is supplied at the first seating timing, the toilet body 30 can be prevented from being used without any reservoir water. Therefore, by reducing the continuous seating time corresponding to the first seating determination value, there is no possibility that the stool is made without water accumulation. On the other hand, if the user finally sits for a stool after repeating sitting and unseating for undressing, he / she sits continuously for a long time compared to the previous sitting time. Therefore, it is necessary to set the determination value to a long time. Therefore, the control device 6 increases the continuous seating time corresponding to the second seating determination value, and if it is determined that the seating is determined based on the determination value, the control device 6 determines that the user is sitting, and then the user leaves the seat. When it is determined that the water has been collected, the stored water in the toilet body 30 is drained. Accordingly, the toilet seat body has a first seating determination value corresponding to a short continuous seating time and a second seating determination value corresponding to a long continuous seating time, and performing seating determination and seating determination separately using each of them. It is configured so that water supply and drainage can be performed accurately without making a mistake in the determination of sitting and leaving to 30.

  Further, as described above, the pressure feeding device 8 is connected to the first intake port connected to the discharge port 2a for taking in the waste water passing through the toilet body 30 and to the crushing part water supply path 4b for taking in the waste water not passing through the toilet body 30. A second intake is provided. Correspondingly, the control device 6 is configured to drain water in the pressure feeding device 8 regardless of the operation of using the toilet body 30.

  In addition to the first intake port for taking in the waste water that passes through the toilet body 30 in the pumping device 8, the second intake port for taking in the waste water that does not go through the toilet body 30 is provided. It is possible to accept wastewater from Furthermore, since the drainage in the pumping device 8 can be performed regardless of the operation of the toilet body 30, it is possible to appropriately drain the drainage from other watering devices received from the second intake port. The influence on the use of 30 can be reduced. By adopting such a configuration, only by providing a fixed-side water supply / drainage facility (see FIGS. 2 and 3) that is a means of water supply / drainage for the flushing / moving toilet 10, without providing a separate water supply / drainage facility for the hand-washer 70. The water supply / drainage environment of the hand-washing device 70 can be adjusted.

  Further, the control device 6 can selectively execute the first water amount mode or the second water amount mode in which cleaning is performed with a smaller amount of water than the first water amount, and one of the first water amount mode and the second water amount mode. It is comprised so that the selection means to perform may be provided. Further, as described above, the control device 6 controls so that the water is stored in the toilet body 30 and is not sealed, and the water is stored in the pressure feeding device 8 so as to constitute the sealed water during standby. ing. In addition, when the signal output from the selection means instructs the execution of the first water amount mode, the control device 6 starts supplying water for storing water in the toilet body 30, while the selection means If the signal output from the controller instructs the execution of the second water amount mode, the water supply amount for storing water in the toilet body 30 is controlled to be smaller than the water supply amount in the first water amount mode. Yes.

  Thus, since the 1st water volume mode and the 2nd water volume mode are comprised so that selection is possible, the mode from which a water supply amount differs can be performed based on a user's intention. Therefore, the first water amount mode and the second water amount mode are selectively used for the large use and the small use, and the first water amount mode and the second water amount mode are selected depending on whether the defecation amount is large or small even if the large use. It is possible to vary the amount of water used according to the usage situation, such as using properly.

  Moreover, the control apparatus 6 respond | corresponds to the predetermined operation signal input based on a user's operation separately from the normal water supply / drainage control performed at the time of the normal use of the flush pressure-transfer mobile toilet 10, and the normal water supply / drainage control. The special water supply / drainage control can be executed only once each time, and a selection instruction means is provided for switching between the normal water supply / drainage control and the special water supply / drainage control.

  In this way, there is a special water supply / drainage control that is switched from the normal water supply / drainage control by the selection instruction means, and the special water supply / drainage control corresponds to the operation signal input based on the operation of the user each time. Since it is executed only once, special water supply / drainage of a pattern different from normal water supply / drainage that allows normal wastewater to flow based on the user's intention can be executed. Therefore, by making the aspect of the special water supply / drainage correspond to various problems peculiar to the flush pumping mobile toilet 10, the problems peculiar to the flush pumping mobile toilet can be flexibly solved. Details of the special water supply / drainage control will be described later.

  The operation of the flushing / moving toilet 10 controlled by the control device 6 outlined above will be described with reference to the flowcharts shown in FIGS. First, basic water supply / drainage control will be described with reference to FIGS. 6 to 8 are flowcharts for explaining basic water supply / drainage control. The amount of stored water, the amount of water supplied, and the amount of water injected in the following description are appropriately changed according to the ball capacity of the toilet body 30.

  In step S01, the flushing / moving toilet 10 is in a standby state. In this case, water is not stored in the toilet body 30, and sealed water is formed in the pressure feeding device 8. The water level in the pumping device 8 is the sealed standby water level L2 (see FIG. 4). At this stage, the toilet main body 30 is not filled with water, the flap valve 9 is closed, and the sealed water is constructed in the pressure feeding device 8, so that even if the flushing / feeding movable toilet 10 is moved, There is no water leakage at the time of a fall or collision, and safety during transportation is achieved. Moreover, generation | occurrence | production of the odor in this state can be suppressed by maintaining cleanliness so that a filth may not adhere to the upstream part rather than the sealing water of the pumping apparatus 8. FIG. The process proceeds from step S01 to step S02.

  In step S02, it is detected that the user is seated by the seating detection sensor 301 and the seating detection unit 804, or a switch for storing water in the toilet body 30 is turned on by the operation panel 82 and the operation reception unit 800. Judging. As a result of the determination, if any is detected, the process proceeds to step S03, and if none is detected, the process returns.

  In step S03, 1.4 L of water is supplied to the toilet bowl body 30, and the state is changed to a usable state. The water supply is performed immediately (for example, about 1.5 seconds) after the seating detection or the switch-on is detected in step S02. Subsequent to step S03, step S04 is executed.

  In step S04, whether or not the seating determination is made and it is determined that the toilet main body 30 can be automatically cleaned, or whether the switch for flowing the water stored in the toilet main body 30 is turned on by the operation panel 82 and the operation receiving unit 800. to decide. As a result of the determination, if any is detected, the process proceeds to step S05, and if none is detected, the process returns.

  In step S05, the sealed water in the pressure feeding device 8 is drained. In this embodiment, in order to reduce the size of the pressure feeding device 8, the capacity of the storage tank 40 in the pressure feeding device 8 is minimized. Therefore, if the water stored in the toilet main body 30 is poured into the pressure feeding device 8 while the sealed water remains in the pressure feeding device 8, there is a possibility that the water will overflow. Therefore, in the process of step S05, first, the sealed water in the pressure feeding device 8 is drained, and a space for receiving the water stored in the toilet body 30 is secured in the pressure feeding device 8. In parallel with the process of step S05, the process of step S06 shown in FIG. 7 is executed.

  In step S06, after confirming that the pumping of the sealed water in step S05 is executed without any problem, the toilet body 30 is washed in parallel with the process in step S05. The toilet body 30 is washed by supplying 1.2 L of water to the toilet body 30. Following the process of step S06, the process of step S07 is executed.

  In step S07, the flap valve 9 is opened after confirming that the sealing water pumping in step S05 has been completed without any problem. By opening the flap valve 9, filth and sewage in the toilet body 30 are introduced into the pressure feeding device 8. As described above, although the capacity of the storage tank 40 in the pumping device 8 is compact, the sealed water in the pumping device 8 is drained in the process of step S05, so that the process proceeds without overflowing. Following the process of step S07, the process of step S08 is executed.

  In step S08, the flap valve 9 is closed, and 0.3 L of supplemental water is supplied from the pulverization section water supply path 4b into the pressure feeding device 8. Since the supplementary water is supplied after the flap valve 9 is closed, the water level rises above the flap valve 9 and sufficient water can be secured for the subsequent crushing and pumping process. In addition, when the warm water washing toilet seat function is added to the flushing / pumping mobile toilet 10, the amount of washing water discharged from the warm water washing toilet seat is subtracted from the supplementary water amount and poured into the pumping device 8. Is also a preferred embodiment. For example, if 0.2 L of washing water is discharged from the warm water washing toilet seat, the amount is reduced from the standard supplementary water volume of 0.3 L, and 0.1 L of water is supplemented into the pumping device 8. is there. By doing in this way, it can constitute so that washing water from a warm water washing toilet seat may be used effectively, and excessive supplementary water will not be performed. Subsequent to step S08, step S09 is executed.

  In step S09, the cutter 52 and the impeller 56 are rotated by the rotation of the crushing and pressure-feeding motor 58, and the crushing and pressure-feeding of the filth are executed. The above-described processing from step S05 to step S09 corresponds to the first cleaning step, and from step S10 executed subsequent to step S09 corresponds to the second cleaning step.

  In step S10, after confirming that the pumping of the filth in step S09 has been executed without any problem, 2.5 L of water is supplied to the toilet body 30 in order to perform the second cleaning of the toilet body 30. Following the process of step S10, the process of step S11 is executed.

  In step S11, the flap valve 9 is opened. By opening the flap valve 9, the washed water in the toilet body 30 is introduced into the pressure feeding device 8. Following the process of step S11, the process of step S12 is executed.

  In step S12, it is determined whether or not the above-described number of times of pumping has reached 10. If the above-mentioned number of times of pumping is 10 times or more, it is considered that the inside of the pumping device 8 is dirty, and therefore the strong cleaning process of the pumping device 8 shown in steps S15 to S17 is executed. If the above-described number of pumping times is less than 10, the process of step S13 is executed.

  In step S13, the flap valve 9 is closed, and 1.5 L of supplementary water is supplied from the pulverization section water supply path 4b into the pressure feeding device 8. Since the supplementary water is supplied after closing the flap valve 9, the water level rises above the flap valve 9. Furthermore, since more water is supplied compared to the supplementary water in step S08, the filth scattered on the inner wall of the pumping device 8 can be washed away during the process in step S09. Subsequent to step S13, step S14 is executed.

  In step S <b> 14, the cutter 52 and the impeller 56 are rotated by the rotation of the crushing and pressure feeding motor 58, and cleaning of the storage tank 40 of the pressure feeding device 8 and pumping of the washing water are performed. Following the process of step S14, the process of step S18 is executed.

  Here, the powerful cleaning in the pressure feeding device 8 from step S15 will be described. In step S16, in a state where the water after washing is substantially accumulated in the pressure feeding device 8 as in step S11, the flap valve 9 is closed and 2.5 L of water is supplied from the pulverization section water supply path 4b to the pressure feeding device 8. Supplementary water is made. Since the supplementary water is supplied after closing the flap valve 9, the water level rises above the flap valve 9. The amount of supplementary water in step S16 is larger than that of 2.5 L and 1.5 L in step S13, and the water level in the pressure feeding device 8 further rises, so that the water can be washed to a position substantially above the inner wall of the pressure feeding device 8. Subsequent to step S16, step S17 is executed.

  In step S17, the result is transferred after the crushing and pressure-feeding motor 58 continues the reverse rotation for 5 seconds, so that the cutter 52 and the impeller 56 rotate alternately in the forward and reverse directions, thereby cleaning the storage tank 40 of the pressure-feeding device 8 and its washing water. Is powerfully executed. Following step S17, step S18 is executed.

  In step S <b> 18, 1.7 L of sealing water is supplied into the pressure feeding device 8, and sealed water is constructed in the pressure feeding device 8.

  The above-described water supply / drainage control from step S01 to step S17 is a so-called large water amount control in which washing is performed with a relatively large amount of water so that the stool can be safely stooled. On the other hand, depending on the mode of use of the flushing / pumping mobile toilet 10, it is possible to perform so-called small water volume control in which washing is performed with less water. This small water amount control will be described with reference to FIG. FIG. 9 is a flowchart of the small water amount control. The small water amount control flow shown in FIG. 9 is formed by partially omitting the large water amount control processing steps described with reference to FIGS. 6 to 8.

  In step S20, the flush flushing mobile toilet 10 is in a standby state, similar to step S01 of the large water amount control. In this case, water is not stored in the toilet body 30, and sealed water is formed in the pressure feeding device 8. The water level in the pumping device 8 is the sealed standby water level L2 (see FIG. 4). At this stage, the toilet main body 30 is not filled with water, the flap valve 9 is closed, and the sealed water is constructed in the pressure feeding device 8, so that even if the flushing / feeding movable toilet 10 is moved, There is no water leakage at the time of a fall or collision, and safety during transportation is achieved. Moreover, generation | occurrence | production of the odor in this state can be suppressed by maintaining cleanliness so that a filth may not adhere to the upstream part rather than the sealing water of the pumping apparatus 8. FIG. The process proceeds from step S20 to step S21.

  In step S21, in the same way as in step S02 of the large water flow control, it is detected that the user is seated by the seating detection sensor 301 and the seating detection unit 804, or the operation panel 82 and the operation reception unit 800 supply water to the toilet bowl. It is determined whether a switch for storing in the main body 30 is turned on. As a result of the determination, if any is detected, the process proceeds to step S22, and if none is detected, the process returns.

  In step S22, similarly to step S03 of the large water amount control, 1.4 L of water is supplied to the toilet body 30, and the state is changed to a usable state. The water supply is performed immediately (for example, about 1.5 seconds) after the seating detection or the switch-on is detected in step S02. Following step S22, step S23 is executed.

  In step S23, as in step S04 of the large water flow control, it is determined that seating is determined and it is determined that the toilet body 30 can be automatically cleaned, or the operation panel 82 and the operation reception unit 800 store the water in the toilet body 30. It is determined whether or not the switch for flowing is turned on. As a result of the determination, if any is detected, the process proceeds to step S24, and if none is detected, the process returns.

  In step S24, the toilet body 30 is cleaned. The toilet body 30 is washed by supplying 0.6 L of water to the toilet body 30. Unlike the large water amount control, the sealed water in the pressure feeding device 8 is not drained, and cleaning with a small amount of water is executed. Following the process of step S24, the process of step S25 is executed.

  In step S25, the flap valve 9 is opened as in step S07 of the large water amount control. By opening the flap valve 9, filth and sewage in the toilet body 30 are introduced into the pressure feeding device 8. Following the process of step S25, the process of step S26 is executed.

  In step S26, as in step S09 for controlling the large water amount, the crushing and feeding motor 58 rotates to rotate the cutter 52 and the impeller 56, and the crushing and pumping of filth are executed. In the large water amount control, steps S10 to S14 and steps S15 to S17, which are the second washing steps, are executed after the processing corresponding to step S26. However, in the small water amount control, these steps are skipped and continue. The process proceeds to step S27.

  In step S <b> 27, 1.7 L of sealing water is supplied into the pressure feeding device 8 and the sealed water is constructed in the pressure feeding device 8 as in step S <b> 18 of the large water amount control.

  In step S24 of the small water amount control shown in FIG. 9, the toilet body 30 is washed by supplying 0.6 L of water to the toilet body 30, but the amount of water supplied in step S06 of the large water amount is 1. You may supply more than 2L of water.

  Next, the control in the case where an abnormality occurs in the drainage of the flushing / pumping mobile toilet 10 will be described with reference to FIG.

  In step S30, it is determined whether or not the male joint 12m (see FIG. 3), which is a drainage joint of the flushing / moving toilet 10, is connected to the building-side female joint 14f (see FIG. 3). As a result of this determination, if the male joint 12m is not connected to the female joint 14f, the process proceeds to step S39, and if the male joint 12m is connected to the female joint 14f, the process proceeds to step S31.

  In step S39, the operation of the pump 44 is prohibited, the water supply from the water supply device 4 is also prohibited, and the process returns. On the other hand, in step S31, the drainage abnormality determination threshold value Q1 is read. The drainage abnormality determination threshold value Q1 is obtained by measuring the drainage environment, obtaining a drainage environment measurement value, calculating based on the acquired drainage environment measurement value, and storing it as a reference value. Details of the drainage environment measurement will be described later. Following the process of step 31, the process of step S32 is executed.

  In step S32, the water level in the storage tank 40 is measured and stored at predetermined time intervals by the water level sensor 60 and the water level detection unit 801. Following the process of step S32, the process of step S33 is executed.

  In step S33, it is determined whether the water level rise in the storage tank 40 measured in step S32 has continued for a predetermined flow rate Q3 or more. If the rise in the water level in the storage tank 40 continues continuously for a predetermined flow rate Q3 or more, the process proceeds to step S40, and if not, the process proceeds to step S34.

  In step S34, it is determined whether the water level decrease in the storage tank 40 measured in step S32 has continued for a predetermined flow rate Q2 or more. If the water level decrease in the storage tank 40 continues continuously for a predetermined flow rate Q2 or more, the process proceeds to step S35, and if not continued, the process returns. In step S35, it is determined whether the pump 44 is in operation. If the pump 44 is in operation, the process proceeds to step S36. If the pump 44 is not in operation, the process proceeds to step S44.

  In step S36, it is determined whether the drainage flow rate exceeds the drainage abnormality determination threshold Q1. If the drainage flow rate exceeds the drainage abnormality determination threshold value Q1, it is determined to be normal and the process returns. If the drainage flow rate does not exceed the drainage abnormality determination threshold value Q1, the process of step S37 is executed.

  In step S37, it is determined whether or not the state in which the drainage flow rate does not exceed the drainage abnormality determination threshold Q1 is continued even if the pump 44 is operated and the drainage process is continuously performed four times. As a result, if the drainage flow rate does not exceed the drainage abnormality determination threshold value Q1, it is determined to be normal, and the process returns. If the drainage flow rate exceeds the drainage abnormality determination threshold value Q1, it continues. Execute the process.

  In step S38, drainage error processing is executed on the assumption that some error has occurred in the drainage path. As the drainage error process, the system stop of the flushing / pumping mobile toilet 10, the drainage stop by blocking the drainage path, and the drainage error display are executed.

  In step S40, it is determined whether the storage tank 40 is being supplied with water. If the water is being supplied to the storage tank 40, the process proceeds to step S45. If not, the process proceeds to step S41.

  In step S41, it is determined whether the water level in the storage tank 40 is equal to or higher than the pump operation start water level L3 that is the standby water level (see FIG. 4 and FIG. 18 showing each water level with respect to the discharge port 2a). If it is not higher than the pump operation start water level L3, it returns that there is no particular abnormality, and if it is higher than the pump operation start water level L3, the process proceeds to step S42. It is assumed that the drainage from the hand-washer 70 is flowing into the pump operation start water level L3 or higher even when the water supply is not being performed. In step S42, the pump 44 is driven to perform a drainage operation. The process which performs operation | movement 3 times continuously is performed. In step S43 following step S42, the water level in the storage tank 40 is equal to or higher than the pump operation start water level L3 even after three consecutive drains, that is, four or more times in succession to the pump operation start water level L3. Judge whether or not. If the pump operation start water level L3 is not lower than 4 consecutive times, the process of step S44 is executed, and if it is not higher than the pump operation start water level L3, the process returns.

  In step S44, water / drainage error processing is executed on the assumption that some error has occurred in the water / drainage path. As the water supply / drainage error processing, the system stop of the flushing pressure transfer mobile toilet 10, the water supply / drainage stop by blocking the water supply / drainage path, and the water / drainage error display are executed.

  In step S45, it is determined whether the water level in the storage tank 40 is equal to or higher than the first allowable limit water level L5. Since step S45 is the result of the determination that water is being supplied in step S40, if the water level is not equal to or higher than the first allowable limit water level L5, it is determined that the water supply state is normal and the process returns. On the other hand, if it is equal to or higher than the first allowable limit water level L5, the process of step S44 is executed.

  Next, the environmentally-adapted process control of the flushing / moving toilet 10 will be described with reference to FIG.

  In step S50, it is determined whether the flush-pumping mobile toilet 10 is connected to a commercial power source. If the flush-washing mobile toilet 10 is not connected to the commercial power source, the process returns. If the flush-feeding mobile toilet 10 is connected to the commercial power source, the process of step S51 is executed.

  In step S51, it is determined whether or not this environmental adaptation process has already been executed. If it is determined that the joint sensor 15s and the joint identification unit 803 are installed at the same place, or if it is determined that the joint sensor 15s and the joint identification unit 803 are not moved, it is determined that the environmental adaptation process has been performed, and step S52 is performed. If the environmental adaptation process has not been executed, the process of step S53 is executed.

  In step S52, the drainage abnormality determination threshold value Q1 recorded as suitable for the installation location is read. Note that the recording mode of the drainage abnormality determination threshold value Q1 may be an overwrite recording mode. In this case, the recorded drainage abnormality determination threshold value Q1 is read. Further, the recording mode of the drainage abnormality determination threshold value Q1 may be a recording mode in which overwriting is recorded every about five recording blocks. In this case, the latest drainage abnormality determination threshold value Q1 of a suitable recording block is read. If the joint sensor 15s and the joint identification unit 804 can identify which joint on the building side is connected, it is possible to automatically select a suitable recording block.

  In step S53, the display unit 808 and the abnormality display unit 63 check the drainage environment and display that the environmental adaptation process is being performed, and wait for a permission instruction input from the user. In a succeeding step S54, it is determined whether or not a permission instruction is input from the user. If there is a permission instruction input from the user, the process of step S55 is executed, and if there is no permission instruction input from the user, the process of step S60 is executed. In step S60, a process for restricting normal use of the flushing and feeding mobile toilet 10 is executed. As a regulation mode for normal use, there are those in which the display unit 808 and the abnormality indicator 63 perform a system stop of the flush toilet pump 10 and a usage regulation notification.

  In step S55, it is determined whether the water supply hose SH and the drainage hose DH are connected to the joint on the building side. If the water supply hose SH and the drainage hose DH are connected to the building-side joint, the process of step S56 is executed. If the water supply hose SH and the drainage hose DH are not connected to the building-side joint, the process of step S60 described above is performed. Execute.

  In step S56, a check for poor connection of the drainage hose DH is performed. Specifically, 2 L of water is supplied into the pressure feeding device 8 and drainage is performed while gradually increasing or changing the rotational speed of the pump 44. As a result, if water leakage is confirmed in the drain hose DH, the water leakage confirmation notification is executed by the display unit 808 and the abnormality indicator 63.

  In step S57, it is determined whether or not normality is determined as a result of the connection failure check in step S56. If it is determined to be normal, the process of step S58 is executed. If it is not determined to be normal, the process of step S60 described above is executed.

  In step S58, a drainage environment check is executed. Specifically, 2 L of water is supplied into the pressure feeding device 8, the pump 44 is driven by normal rotation, and pressure feeding is performed, and the drainage flow rate Q by the pressure feeding is measured. The drainage abnormality determination threshold value Q1 is calculated from this drainage flow rate Q as Q1 = Q × 0.6, and the calculated drainage abnormality determination threshold value Q1 is recorded. In a succeeding step S59, a normal use permission notice is displayed by the display unit 808 and the abnormality indicator 63.

  In this embodiment, the drainage abnormality determination threshold value Q1 is calculated as Q1 = Q × 0.6, but the calculation method is not limited to this. It is also preferable to calculate as Q1 = Q × 0.8 so that the amount of decrease in the drainage abnormality determination threshold value Q1 becomes small if the drainage flow rate Q is large. By adjusting the drainage abnormality determination threshold value Q1 in this way, it is possible to achieve both the avoidance of defective drainage and the prevention of erroneous drainage abnormality determination at a high level. When the drainage abnormality determination threshold Q1 is a low value, it is also preferable to increase the number of continuous abnormality determinations (step S43 and step S37) described in FIG.

  Further, in this embodiment, the drainage abnormality determination threshold Q1 is configured to vary, but the drainage abnormality determination is performed using the second drainage abnormality threshold Qf as a fixed value that is not updated separately from the drainage abnormality determination threshold Q1. It is also preferable to carry out. This second drainage abnormality threshold value Qf is set to be stricter (smaller) than the drainage abnormality determination threshold value Q1, and when the drainage state measurement value falls below this second drainage abnormality threshold value Qf, more severe emergency stop measures, etc. It is preferable to execute the drainage abnormality treatment.

  Moreover, it is also preferable to execute the drainage abnormality process when the continuous drainage time from the pressure feeding device 8 continues for a predetermined time or longer, regardless of the drainage abnormality determination threshold Q1. It is also preferable to hold an emergency judgment threshold value Qu that is 1.5 times the drainage flow rate Q, and to make an emergency stop when one event occurs when the measured flow rate exceeds the emergency judgment threshold value Qu.

  Next, the provisional abnormality process control of the flushing / feeding mobile toilet 10 will be described with reference to FIG. Step S70 in FIG. 12 is processing corresponding to step 36 in FIG. 10, and the previous processing steps are omitted.

  In step S70, it is determined whether the drainage flow rate exceeds the drainage abnormality determination threshold value Q1. If the drainage flow rate exceeds the drainage abnormality determination threshold value Q1, it is determined to be normal and the process returns. If the drainage flow rate does not exceed the drainage abnormality determination threshold value Q1, the process of step S71 is executed.

  In step S71, it is determined whether or not the state where the drainage flow rate does not exceed the drainage abnormality determination threshold Q1 is continued even if the pump 44 is operated and the drainage treatment is executed three times in succession. As a result, if the drainage flow rate does not exceed the drainage abnormality determination threshold Q1, the cleaning process of step S75 is executed, and if the drainage flow rate exceeds the drainage abnormality determination threshold Q1, the process of step S72 is performed. Execute. In step S75, the display unit 808 and the abnormality indicator 63 indicate that the cleaning operation is being performed, and the pump 44 is rotated reversely or forward / reversely reversed to agitate the inside of the storage tank 40 and return. By the cleaning process in step S75, pulsation is generated in the water distribution pipe, and removal of clogging of the drain hose DH is promoted.

  In step S72, it is determined whether the state in which the drainage flow rate does not exceed the drainage abnormality determination threshold Q1 is continued even if the pump 44 is operated and the drainage process is continuously performed four times. As a result, if the drainage flow rate does not exceed the drainage abnormality determination threshold Q1, the cleaning process of step S76 is executed, and if the drainage flow rate exceeds the drainage abnormality determination threshold Q1, the process of step S73 is performed. Execute. In step S76, the display unit 808 and the abnormality display 63 indicate that the cleaning operation is being performed, and the pump 44 is reversely rotated or rotated forward and reverse so that the inside of the storage tank 40 is agitated. After returning twice, return.

  In step S73, it is determined whether or not the state in which the drainage flow rate does not exceed the drainage abnormality determination threshold Q1 is continued even if the pump 44 is operated and the drainage process is continuously performed four times. As a result, if the drainage flow rate does not exceed the drainage abnormality determination threshold Q1, the process returns. If the drainage flow rate exceeds the drainage abnormality determination threshold Q1, the process of step S74 is executed.

  In step S74, the supply of water to the flushing / moving toilet 10 is stopped, and if there is water in the toilet body 30, the flap valve 9 is opened and conveyed into the storage tank 40 of the pumping device 8. Then, the water in the storage tank 40 is drained and stopped. After this stop, the display unit 808 and the abnormality indicator 63 notify that the drainage is abnormal.

  In this embodiment, the water is stopped without supplying water, but it is also preferable that water is stored in the toilet body 30 and stopped while holding the water.

  Next, the seating determination control for performing the seating determination and the seating determination of the flushing and feeding mobile toilet 10 will be described with reference to FIGS. 13 to 15. FIG. 13 is a flowchart of the seating determination control, and FIGS. 14 and 15 are diagrams for explaining the first seating determination value and the second seating determination value for seating determination. In FIG. 14, “Lo” indicates that no seating detection signal is output from the seating detection sensor 301 and the seating detection unit 803, and “Hi” indicates that it is output. T1 to t2 is about 2 seconds, t2 to t3 is about 2 seconds, t3 to t4 is about 4 seconds, t4 to t5 is about 8 seconds, t5 to t6 is about 1 second, t6 to t7 is about 2 seconds Yes, t1 to t7 is about 19 seconds.

  In step S80, it is determined whether a seating detection signal is output from the seating detection sensor 301 and the seating detection unit 803. If the seating detection signal is not output, the process returns, and if it is output, the process of step S81 is executed.

  In step S81, the seating determination is executed using the first seating determination value. Specifically, the first seating determination value 2 seconds is compared with the time during which the seating detection signal is output from the seating detection sensor 301 and the seating detection unit 803, and the seating detection sensor 301 and the seating detection unit are compared. If the time during which the seating detection signal is output from 803 is less than the first seating determination value, the process returns, and if it exceeds, the process of step S82 is executed.

  In step S82, the first seating determination, which is a seating determination, is permitted, and water is supplied into the toilet main body 30 to store water. In subsequent step S83, the second seating determination value is used to perform the seating determination. Specifically, the second seating determination value of 20 seconds is compared with the time during which the seating detection signal is output from the seating detection sensor 301 and the seating detection unit 803, and the seating detection sensor 301 and the seating detection unit are compared. If the time during which the seating detection signal is output from 803 is less than the second seating determination value, the process returns, and if it exceeds, the process of step S84 is executed.

  In step S84, the second seating determination, which is a seating determination, is permitted, and if the seating detection signal is not output from the seat detection sensor 301 and the seating detection unit 803, drainage is permitted as having been seated.

  By performing the seating determination and the seating determination in this way, for example, an elderly person who does not have much freedom of body, even when preparing to defecate while repeatedly sitting and standing on the toilet body, Water can be stored and drained. When such people use the flush-pumping mobile toilet 10, a seating detection signal as shown in FIG. 14 may be output. In the example shown in FIG. 14, the user first sits at t1 and prepares for defecation while repeating the seating and separation until t7, and performs the defecation operation after t7.

  If the above-described seating determination control is performed, it is determined that the short-time seating such as t2 to t3 is not a full-scale seating, so that wasteful drainage at this timing can be prevented. Further, if the seating continues after t7, the subsequent seating can be determined as a full seating.

  Here, as shown in FIG. 14, since it is later found out that full-fledged seating has been made at t7, it is also preferable to treat the time from t1 to t7 as the seating preparation time. It is also preferable to measure and store the seating preparation time, and to determine the second seating determination value based on the average time for three times of the seating preparation time. In this way, as shown in FIG. 15, the second seating determination value can be varied between 10 seconds and 120 seconds, and linked to the seating preparation time. By linking the seating preparation time and the second seating determination value, the second seating determination value can be determined according to the level of the user's body, such as the degree of disability, and erroneous determination is more effectively prevented. be able to.

  By the way, when the seating determination control as shown in FIG. 13 is executed, there may be a case where the accumulated water in the toilet body 30 is not drained, for example, when defecation is stopped before reaching t7 in FIG. Therefore, it is preferable to perform forced drainage control as shown in FIG.

  In step S90, it is determined whether or not there is water in the toilet body 30. If there is accumulated water in the toilet body 30, the process of step S91 is executed, and if there is no accumulated water in the toilet body 30, the process returns. In step S91, it is determined whether the sitting state continues for 15 minutes. The separated state is determined based on whether a seating detection signal is output from the seating detection sensor 301 and the seating detection unit 803. If the separated state continues for 15 minutes, the process of step S93 is executed, and if the separated state does not continue for 15 minutes, the process of step S92 is executed.

  In step S <b> 92, it is determined whether or not the state in which the toilet body 30 has accumulated water continues for 30 minutes. If the state in which the toilet body 30 has accumulated water does not continue for 30 minutes, the process returns. If the state in which the toilet body 30 has accumulated water continues for 30 minutes, the process of step S93 is executed. In step S93, the same drainage sequence as the normal cleaning of the toilet main body 30 is executed to forcibly drain the water stored in the toilet main body 30.

  In addition, it is also preferable to determine whether or not forced drainage can be performed by omitting the separation determination in step S91 and only the continuation determination in step S92. It is also preferable to learn and change the determination reference time in step S91 and step S92 according to the sitting time. For example, it is also preferable to determine such that three times the average seating time is set as the determination reference time, the lower limit time is 30 minutes, and the upper limit time is 1 hour.

  Next, the hand-washing drainage control of the flush-pumping mobile toilet 10 will be described with reference to FIG.

  In step S <b> 100, it is determined whether or not the flushing and feeding mobile toilet 10 is in use. If the flush-washing / moving toilet 10 is in use, the process of step S101 is executed. If the flush-washing / transferring toilet 10 is not in use, the process of step S108 is executed.

  In step S <b> 101, it is determined whether or not the process proceeds to a step of conveying sewage from the toilet body 30 to the storage tank 40 of the pressure feeding device 8. If it judges that it transfers to the process of conveying sewage to the storage tank 40, the process of step S110 will be performed, and if it determines not to transfer to the process of conveying sewage to the storage tank 40, the process of step S102 will be performed. In step S110, the process which regulates with respect to use of the hand-washing machine 70 is performed. Specifically, the use restriction of the hand-washing device 70 is notified by the display unit 808 and the abnormality display device 63, and water supply to the hand-washing device 70 is stopped or suppressed.

  In step S102, it is determined whether the flap valve 9 is open. If the flap valve 9 is open, the process of step S110 described above is executed, and if the flap valve 9 is not open, the process of step S103 is executed. In step S103, it is determined whether the water level of the storage tank 40 of the pressure feeding device 8 exceeds the first allowable limit water level L5. If the water level in the storage tank 40 of the pumping device 8 exceeds the first allowable limit water level L5, the process of step S110 described above is executed. If the water level does not exceed the first allowable limit water level L5, the process of step S104 is executed. .

  In step S104, it is determined whether the water is being drained from the storage tank 40 of the pumping device 8. If draining from the storage tank 40, the process returns. If not draining from the storage tank 40, the process of step S105 is executed. In step S105, it is determined whether the storage tank 40 of the pressure feeding device 8 is being supplied with water. If the water is being supplied to the storage tank 40, the process of step S111 is executed. If the water is not being supplied to the storage tank 40, the process of step S106 is executed. In step S111, control is performed so that the water level in the storage tank 40 is maintained in the vicinity of the pump operation start water level L3 that is in a standby allowable transition.

  In step S106, it is determined whether the water level of the storage tank 40 exceeds the toilet water use allowable level L4. If the water level of the storage tank 40 does not exceed the permissible water level L4 when using the toilet bowl, the process returns. If the water level of the storage tank 40 exceeds the permissible water level L4 when using the toilet bowl, the process of step S107 is executed. In step S107, the pump 44 is driven at a low rotation, and the water level in the storage tank 40 is controlled to become the sealed water level L2.

  In step S108, which is executed when it is determined in step S100 that the flush flushing mobile toilet 10 is not in use, it is determined whether the water level in the storage tank 40 exceeds the pump operation start water level L3. If the water level in the storage tank 40 does not exceed the pump operation start water level L3, the process returns. If the water level in the storage tank 40 exceeds the pump operation start water level L3, the process of step S109 is executed. In step S109, the pump 44 is driven at a low rotation, and the water level in the storage tank 40 is controlled to be the sealed water level L2. If it is determined in step S108 that the use of the hand-washer 70 is continued, the determination reference water level may be set to the allowable water level L4 when the toilet is used.

  Next, the special water supply / drainage control of the flushing / moving toilet 10 will be described with reference to FIGS. 19 to 21. 19 is a flowchart showing the stool inspection mode control of the special water supply / drainage control, FIG. 20 is a flowchart showing the conveyance mode control of the special water supply / drainage control, and FIG. 21 is a flowchart showing the strong cleaning mode control of the special water supply / drainage control. .

  In step S121, it is determined whether or not the execution process of the flushing / feeding mobile toilet 10 is after the cleaning process. If the execution process of the flush washing / moving toilet 10 is after the washing process, the process of step S123 is executed, and if the execution process of the flushing / feeding portable toilet 10 is not after the washing process, the process of step S122 is executed. In step S123, the display unit 808 and the abnormality indicator 63 notify that the transition to the stool check mode, which is a special mode, is prohibited.

  In step 122, the stool check mode is executed. Specifically, 0.3 L of stored water is supplied into the toilet body 30. Thereby, the sticking of the stool to the inside of the toilet body 30 can be suppressed. In addition, when the toilet body 30 already has 0.3 L or more of accumulated water, this accumulated water is removed to cope with it. Thereafter, the toilet body 30 is washed while supplying 2.3 L of water.

  As shown in FIG. 20, in step S130, it is determined whether or not the conveyance mode is set. If the transfer mode is set, the process of step S131 is executed. If the transfer mode is not set, the process returns.

  In step 131, it is determined whether the flush flushing mobile toilet 10 is on standby. If the flush-washing / moving toilet 10 is on standby, the process of step S132 is executed. If the flush-washing / transferring toilet 10 is not on standby, the process of step S133 is executed. In step S133, the display unit 808 and the abnormality indicator 63 notify that the shift to the transport mode that is the special mode is prohibited.

  In step S132, the conveyance mode is executed. Specifically, the sealed water in the storage tank 40 of the pumping device 8 is drained, and the display unit 808 and the abnormality indicator 63 notify the permission to remove the water supply / drainage joint (see FIGS. 2 and 3).

  As shown in FIG. 21, in step S140, it is determined whether or not the strong cleaning mode is set. If the strong cleaning mode is set, the process of step S131 is executed. If the strong cleaning mode is not set, the process returns.
