  In such flush flushing toilets, there is a risk of abnormal grinding or abnormal feeding. The pulverization abnormality is an abnormality that occurs in the pulverization operation when a foreign substance such as a paper diaper or metal is erroneously mixed into the pulverization unit having the pulverization cutter. The crushing abnormality may cause, for example, a crushing cutter or pumping drive stop due to entanglement of foreign matter with respect to the rotating shaft, or damage or failure of the pumping unit. The abnormal pressure feeding is an abnormality that occurs in the pressure feeding operation due to clogging of the pressure feeding piping due to the accumulation of foreign matters and crushed pieces in the pressure feeding piping. If a pumping abnormality occurs, crushed dirt and foreign matter may not be discharged to the external drain pipe.

  When such an abnormality occurs in a flush-fed toilet, the effect on the user is enormous. Therefore, it is required to notify in advance of pulverization abnormalities and pressure-feeding abnormalities due to foreign matter mixing, and to promote maintenance before the flushing-type toilet can no longer be used.

  For example, in the flushing pressure-fed toilet described in Patent Document 1, in order to notify a crushing abnormality or a pumping abnormality, a load amount applied to a motor that rotates a rotating shaft of a pulsator or an impeller provided in a crushing unit, and a water level detection unit Based on the detected water level, control is performed to determine and notify at least one of abnormal pumping and abnormal grinding.

[First embodiment]
A first embodiment of the present invention will be described. First, a flush-fed toilet according to this embodiment will be described with reference to FIG. FIG. 1 is a schematic perspective view showing a flush-fed toilet according to an embodiment of the present invention.

  As shown in FIG. 1, the flushing and feeding toilet 1 according to the present embodiment includes a toilet body 20, and a water supply hose 11 and a drainage hose 12 connected to the toilet body 20. The upstream side of each of the water supply hose 11 and the drainage hose 12 is connected to a water supply pipe and a drainage pipe (not shown) piped to the building.

And a pressure feeding device 50 which is a device.

  The toilet body 20 includes a bowl portion 21 that receives filth, a discharge port 22 that discharges the filth, and a drainage channel 23 that allows the bowl portion 21 and the discharge port 22 to communicate with each other. The drainage channel 23 is sealed by the stored water 24.

  The water supply apparatus 4 supplies and cleans the toilet body 20 with water. The downstream side of the water supply device 4 is connected to the toilet body 20 via the water supply pipe 3, and has a water supply valve 4 a made up of an electromagnetic valve or the like in the middle of the water supply pipe 3. On the other hand, the upstream side of the water supply device 4 is connected to the downstream side of the water supply hose 11. The amount of water supplied to the toilet body 20 is adjusted by controlling the opening and closing of the water supply valve 4a by the control device 90 (control unit).

  For example, when a user turns on a washing operation switch of a remote controller (not shown) for washing the toilet main body 20 after using the flush-feed toilet, cleaning water is supplied from the water supply device 4 to the toilet main body 20. The main body 20 is washed with water. In addition, when the seating detection sensor is provided in the toilet body 20 and the seating detection sensor detects that the user sitting on the toilet body 20 is separated, the toilet body 20 is cleaned from the water supply device 4. It is good also as a structure by which water supply is made and the toilet body 20 is supplied and washed.

  The pumping device 50 is provided outside the toilet body 20. The pumping device 50 has a storage tank 51 connected to the outlet 22 of the toilet body 20.

The crushing unit 60 includes a pulsator 61 (crushing means) that crushes filth in wastewater discharged from the outlet 22 of the toilet body 20 into the storage tank 51 and solid matter such as toilet paper. The impeller 70 is provided in the lower part of the crushing part 60, and forcibly feeds the sewage in the storage tank 51 to the outside.

  The crushing unit 60 has a crushing chamber 64 formed by a screen 63 having a plurality of holes 62, and waste water and solid matter discharged from the outlet 22 of the toilet body 20 into the storage tank 51 are first crushing chamber 64. Once accommodated. Of the solid matter in the crushing chamber 64, the solid matter larger than the size of the hole 62 of the screen 63 cannot be passed through the hole 62 and is captured in the crushing chamber 64, and is smaller than the size of the hole 62 of the screen 63. The substance flows out of the crushing chamber 64 through the hole 62 in the storage tank 51.

  A pulsator 61 is provided in the grinding chamber 64. The pulsator 61 is rotatably supported by a rotating shaft 71 arranged in the vertical direction in the grinding chamber 64. As the pulsator 61 rotates, the solid matter that cannot pass through the holes 62 of the screen 63 and is captured in the crushing chamber 64 is crushed.

  The impeller 70 shares a rotating shaft with the pulsator 61 and is attached to the lower end of the rotating shaft 71 of the pulsator 61 that extends downward from the inside of the crushing chamber 64 to the outside of the crushing chamber 64. As the impeller 70 rotates, the sewage and solid matter that have flowed out of the crushing chamber 64 through the holes 62 of the screen 63 in the storage tank 51 are stored through the pressure feed pipe 53 connected to the storage tank 51. It is pumped out of the tank 51. On the other hand, a crushing and pressure feeding motor 52 that drives the rotary shaft 71 so as to be able to rotate forward and backward is attached to the upper end of the rotary shaft 71. The pulverizer 61 and the impeller 70 are driven to rotate coaxially by driving the crushing and pressure-feeding motor 52 and rotating the rotary shaft 71.

  The water level detection sensor 80 is a pressure-sensitive water level detection sensor having a hollow tube 81 and a pressure-sensitive portion 82. In the water level detection sensor 80, when the opening lower end portion 81 a of the cavity pipe 81 is submerged, the air in the cavity pipe 81 is airtight by the water surface of the opening lower end portion 81 a and the pressure sensitive portion 82 provided at the upper end of the cavity pipe 81. It becomes a state. In the water level detection sensor 80, the pressure sensing unit 82 senses the water pressure through the air in the hollow pipe 81. A considerable water level in the storage tank 51 is output according to the water pressure sensed by the pressure sensing unit 82. Thus, the water level detection sensor 80 can detect the water level in the storage tank 51 in a non-contact manner.

  The water level in the storage tank 51 detected by the water level detection sensor 80 is determined in consideration of the amount of drainage discharged from the toilet body 20 by one washing, the drainage capacity of the crushing and pumping motor 52, the capacity of the storage tank 51, and the like. L1 is set.

  Further, since the water level cannot be measured when the water level in the storage tank 51 falls below the position of the opening lower end portion 81a, the distance h between the bottom surface in the storage tank 51 and the opening lower end portion 81a is made as small as possible to lower the opening lower end portion. 81a is preferably in a low position. However, the distance h is preferably set to 10 mm (millimeters) or more so that no dirt is caught between the bottom surface in the storage tank 51 and the lower end 81a of the opening.

  On the other hand, about the diameter D of the opening lower end part 81a, 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 81a of the cavity pipe | tube 81 may be set smaller than 20 mm, and the substantial capacity | capacitance in the storage tank 51 may be used.

  In the present embodiment, an example is described in which a pressure-sensitive sensor is used as the water level detection sensor 80, but other types of sensors such as an ultrasonic sensor may be used in addition to this sensor. . As a configuration for detecting the water level inside the storage tank 51, for example, a mode in which the pressure is detected by a potential and the water level is calculated by the control device 90 is also preferable.

  When the user turns on the washing operation switch of the remote control 98 for washing the toilet body 20, the control device 90 outputs a valve opening signal to the water supply valve 4 a, controls the valve opening, and crushing and pressure feeding motor 52. The motor drive start signal is output to the rotary shaft 71 to rotate. Further, the control device 90 outputs a motor drive stop signal to the crushing and pressure-feeding motor 52 after a predetermined time has passed since the motor driving start signal was output to the crushing and pressure-feeding motor 52 (25 seconds in this embodiment). Output.

  Further, the control device 90 determines whether or not the crushing and feeding motor 52 has actually stopped based on the rotation speed of the rotating shaft 71 of the crushing and feeding motor 52 detected by the rotation number detecting unit 52a. It has a determination means 91a and a stop time measuring means (measurement means) 91b for measuring a stop time from the output of the motor drive stop signal to the stop of the rotary shaft 71 of the crushing and pressure feeding motor 52. Details of the control device 90 will be described later.

  When the stop time measured by the stop time measuring unit 91b and the water level detected by the water level detection sensor 80 satisfy the first condition, the notification unit 55 notifies the pulverization abnormality of the pulverization operation in the pulverization unit 60. In addition, the notification unit 55 performs the pumping abnormality of the pumping operation of pumping to the outside of the storage tank 51 when the stop time measured by the stop time measuring unit 91b and the water level detected by the water level detection sensor 80 satisfy the second condition.

In this way, the notification unit notifies the user or the maintenance worker of the abnormal state that has occurred in the flushing toilet 1. Details of the notification unit 55 will be described later.

Next, the specific example of operation | movement of the flushing pressure type toilet bowl which concerns on 1st Embodiment of this invention is demonstrated using FIG.5 and FIG.6.
FIG. 5 is a main flowchart illustrating a specific example of the operation of the flushing and toilet bowl according to the first embodiment of the present invention. FIG. 6 is a sub-flowchart illustrating a specific example of the operation of the flushing and pumping toilet according to the first embodiment of the present invention.
In addition, the water supply amount in the following description can be appropriately changed according to the capacity of the bowl portion 21 of the toilet body 20.

  First, when the flush flushing toilet 1 is turned on (step S101), the flush flush toilet 1 enters a standby mode (step S102). At this time, the toilet body 20 is in a state in which sealed water is formed by the stored water 24, and the water level in the storage tank 51 is the standby water level L2 (see FIG. 2). Moreover, the control apparatus 90 lights the 1st state display means 55a of the alerting | reporting part 55 green (refer FIG. 4). Thereby, a user and an operator are alert | reported that the power supply of the flush pressure-feed type toilet 1 is turned on. Note that when the power is turned off at this time, the flushing pressure-fitted toilet 1 ends its operation.

  Subsequently, when the washing operation switch of the remote controller 98 for flowing the toilet body 20 is turned on by the user (step S103), the control device 90 receives the toilet washing signal from the remote controller 98, and the water supply valve 4a is opened. Thus, a water supply valve drive signal is output to the water supply valve 4a. Thereby, wash water is supplied to the toilet bowl main body 20, and the toilet bowl main body 20 is wash | cleaned (step S104). At this time, solids and sewage in the bowl portion 21 of the toilet body 20 pass through the drainage channel 23 and are discharged into the grinding chamber 64 of the storage tank 51. The toilet body 20 is washed by supplying 5.5 L of water to the toilet body 20. In addition, a reservoir 24 is formed and sealed in the drainage channel 23.

Subsequently, the control device 90 outputs a motor drive start signal to the crushing and pressure feeding motor 52. As a result, the crushing and pressure-feeding motor 52 starts to drive, and the pulsator 61 and the impeller 70 start to rotate. When the pulsator 61 and the impeller 70 are rotationally driven, the solid matter trapped in the pulverization chamber 64 is pulverized, and the solid matter and sewage that have flowed out from the pulverization chamber 64 to the outside of the pulverization chamber 64 in the storage tank 51. The pressure feeding is executed (step S105).
Subsequently, when 25 seconds have elapsed from the start of driving of the crushing and pressure feeding motor 52, the process proceeds to step S201 shown in FIG. 6 (step S106). The control device 90 lights the second state display means 55b in red for 25 seconds from the start of driving of the crushing and pressure feeding motor 52 (see FIG. 4). Thereby, a user and an operator are alert | reported that the flush toilet-type toilet 1 is in the crushing pumping operation.

  When 25 seconds have elapsed from the start of driving of the crushing and pressure feeding motor 52, the control device 90 outputs a motor drive stop signal to the crushing and pressure feeding motor 52 (step S201). Subsequently, the control device 90 starts measurement by the stop time measuring unit 91b (step S202). Subsequently, the control device 90 determines whether or not the rotational speed A of the crushing and pressure feeding motor 52 is zero (step S203). If the rotational speed A is not zero (step S203: NO), the measurement by the stop time measuring means 91b is continued until the rotational speed A of the crushing and pressure-feeding motor 52 becomes zero (step S203). If the rotational speed A is zero (step S203: YES), the measurement by the stop time measuring means 91b is terminated (step S204). Thus, the stop time t is measured by the process from step S202 to step S204. The stop time t indicates the time from when the control device 90 outputs a motor drive stop signal to the crushing and pressure feeding motor 52 until the crushing and pressure feeding motor 52 stops.

  Next, the control device 90 determines whether or not the stop time t is longer than the first predetermined time T1 (step S205). Here, the “first predetermined time T1” means that the pulverization is performed after the motor drive stop signal is output to the pulverization / pumping motor 52 obtained when the flushing / pumping toilet 1 according to the present embodiment is installed on the site. This time is set based on the initial stop time T0 (drainage environment measurement value) until the pumping motor 52 stops. For example, when the initial stop time T0, which is one of the drainage environment measurement values, is 3 seconds, the first predetermined time T1 is set to 2 seconds. It should be noted that the shorter the stop time t is than the time T0, the greater the load applied to the crushing and pressure feeding motor 52.

  When the stop time t is longer than the first predetermined time T1 (step S205: YES), the control device 90 determines that there is no abnormality in the operation of the flush flush toilet 1 and resets the stop time (step S206). If it is determined that there is no abnormality in the operation of the flush-washing toilet 1, the process proceeds to the above-described step S102 shown in FIG. 5 (step S207).

  On the other hand, when the stop time t is equal to or shorter than the first predetermined time T1 (step S205: NO), it is determined whether or not the stop time t is longer than the second predetermined time T2 (step S208). Here, the “second predetermined time T2” is a time shorter than the first predetermined time T1, and after the motor driving stop signal is output to the crushing and pressure feeding motor 52, the crushing and pressure feeding motor 52 stops. It is the time set based on time T0 (drainage environment measurement value). For example, when the time T0 that is one of the drainage environment measurement values is 3 seconds, the second predetermined time T2 is set to 1 second.

  When the stop time t is longer than the second predetermined time T2 (step S208: YES), it is determined whether or not the water level L in the storage tank 51 is equal to or higher than the determination water level L1 (step S209). Here, the “determination water level L1” is a water level that is higher than the standby water level L2, and is a fixed value that is set lower than the water level at which the storage tank 51 becomes full. This “determination water level L1” is a water level that cannot be reached under normal operation of the flushing pressure-fitted toilet 1. When the water level L in the storage tank 51 is equal to or higher than the determination water level L1 (step S209: YES), the control device 90 has an abnormality in the pressure feeding operation due to clogging of the pressure feeding pipe 53 (hereinafter referred to as “pressure feeding abnormality” for convenience of explanation). The notification unit 55 notifies the occurrence of the abnormal pumping (step S210). At this time, the flush flushing toilet 1 according to the present embodiment alerts the user to perform maintenance by notifying that the abnormality in the pressure feeding has occurred by the notification unit 55, but since it is in a usable state, step S210 In the next step, the process returns to the above-described step S102 shown in FIG. 5 (step S211).

  The control device 90 causes the first state display means 55a and the second state display means 55b to blink simultaneously in red until no abnormal pumping state is detected (see FIG. 4). Further, the control device 90 repeatedly outputs the voice “The pressure abnormality has been detected. Please contact XX” repeatedly by the voice output means 55d. As a result, the user or the operator is informed that a pressure feeding abnormality has been detected.

  In the specification of the present application, “clogging of the pressure feeding pipe 53” refers to a state in which the inside of the pressure feeding pipe 53 is not completely closed and a part thereof is closed. Therefore, when the clogging of the pressure feeding pipe 53 occurs, the drainage flow rate per unit time when the water inside the storage tank 51 is drained to the outside of the storage tank 51 through the pressure feeding pipe 53 decreases, and the inside of the storage tank 51 at that time The water level becomes higher than the case where the clogging of the pressure feeding pipe 53 is not caused.

  On the other hand, when the water level L in the storage tank 51 is less than the determination water level L1 (step S209: NO), the controller 90 causes an abnormality in the pulverization operation due to the mixing of foreign matter into the pulverization unit 60 (hereinafter, for convenience of explanation). It is determined that the “pulverization abnormality” has occurred, and the notification unit 55 notifies the occurrence of the pulverization abnormality (step S212). At this time, the flushing pressure-fed toilet 1 according to the present embodiment alerts the maintenance to be performed by notifying that the pulverization abnormality has occurred by the notification unit 55, but since it is in a usable state, step S212. In the next step, the process returns to the above-described step S102 shown in FIG. 5 (step S211).

  The controller 90 causes the second state display means 55b and the third state display means 55c to blink simultaneously in red until no abnormal grinding state is detected (see FIG. 4). Further, the control device 90 repeatedly outputs the sound “The pulverization abnormality has been detected. Please turn off the product and clean the pulverization chamber” five times by the audio output means 55d. As a result, the user or the operator is notified that the crushing abnormality has been detected.

  When the stop time t is equal to or shorter than the second predetermined time T2 (step S208: NO), it is determined whether or not the switch of the water level detection sensor 80 is on (step S213). When the switch of the water level detection sensor 80 is on (step S213: YES), the control device 90 determines that a pressure feeding abnormality has occurred, and notifies the notification unit 55 that the pressure feeding abnormality has occurred (step S214). ). Subsequently, the control device 90 prohibits the driving of the crushing and pressure feeding motor 52 and the water supply device 4 (step S216). Then, the toilet bowl cleaning operation is terminated.

  Note that the control device 90 simultaneously lights the first state display means 55a and the second state display means 55b in red until no abnormal pumping state is detected (see FIG. 4). Furthermore, the control device 90 repeatedly outputs the voice “The product has an abnormality. The product is in an unusable state. This notifies the user and the operator that a pressure-feed abnormality has been detected and that the flush-washing toilet 1 has been disabled.

  Thus, in the process of step S214, the flushing pressure-fed toilet 1 according to the present embodiment notifies the operator 55 that the pumping abnormality has occurred by notifying the notification unit 55, and prompts attention to perform maintenance. In the processing, the pulverization and pressure feeding motor 52 and the water supply device 4 are prohibited from being used, thereby making the state unusable. Thereby, it is possible to prevent water from overflowing from the toilet main body 20 by using the flush flushing toilet 1 while an abnormality has occurred in the flush flush toilet 1.

  On the other hand, when the switch of the water level detection sensor 80 is OFF (step S213: NO), the control device 90 determines that a crushing abnormality has occurred, and notifies the informing unit 55 that the crushing abnormality has occurred ( Step S215). Subsequently, the control device 90 prohibits the driving of the crushing and pressure feeding motor 52 and the water supply device 4 (step S216). Then, the toilet bowl cleaning operation is terminated.

  Note that the control device 90 simultaneously turns on the second state display means 55b and the third state display means 55c in red until no abnormal grinding state is detected (see FIG. 4). Furthermore, the control device 90 repeatedly outputs the voice “The product has an abnormality. The product is in an unusable state. This notifies the user and the operator that a crushing abnormality has been detected and that the flushing pressure toilet 1 has been disabled.

  Thus, in the process of step S215, the flushing pressure toilet 1 according to the present embodiment informs the occurrence of the pulverization abnormality by the notification unit 55, thereby prompting attention to perform maintenance, and in step S216. In the processing, the pulverization and pressure feeding motor 52 and the water supply device 4 are prohibited from being used, thereby making the state unusable. Thereby, it can prevent that water overflows from the toilet bowl main body 20 by using it while the abnormality occurs in the flushing pressure-feed type toilet bowl 1.

  As described above, in the flushing pressure-fed toilet 1 according to this embodiment, when the first condition is satisfied, the notification unit 55 notifies the pulverization abnormality, and when the second condition is satisfied, the notification unit 55 causes the pumping abnormality. Inform. Here, the first condition is that the stop time t is shorter than the first predetermined time T1, and the water level in the storage tank 51 is less than the determination water level L1. The second condition is that the stop time t is shorter than the first predetermined time T1, and the water level in the storage tank 51 is equal to or higher than the determination water level L1. Thus, the notification unit 55 determines whether or not the stop time measured by the stop time measuring unit 91b is shorter than the first predetermined time T1, and the water level detected by the water level detection sensor 80 is equal to or higher than the determination water level L1. Because it is based on whether or not there is, it is not necessary to make complicated judgments, it is possible to accurately notify abnormalities in pumping and crushing with a simple configuration, and prompt maintenance before the flushing toilet 1 can no longer be used. Can do.

  Moreover, in the flush pressure-fed toilet 1 which concerns on this embodiment, the control apparatus 90 measures the measured value measured when installing a flush pressure-fed toilet as a drainage environment measurement value, and based on the drainage environment measurement value A first predetermined time T1 and a second predetermined time T2 are set. And since the alerting | reporting part 55 alert | reports a pumping abnormality and a grinding | pulverization abnormality based on the set predetermined time, it can perform appropriate alerting | reporting according to drainage environment.

  Further, in the flush toilet 1 according to the present embodiment, the control device 90 urges attention to perform maintenance by notifying that the abnormality in pumping or pulverization has occurred by the notification unit 55, but is in a usable state. When notifying the occurrence of a pumping abnormality by the notification unit 55 and urging attention to perform maintenance, and prohibiting the driving of the crushing and pumping motor 52 and the water supply device 4 to supply water to the toilet body. In case of disabling the discharge of sewage and filth, control is performed. Therefore, it is possible to prevent the flushing pressure toilet 1 from being used unnecessarily.

  It should be noted that the stop time in the time region shorter than the first predetermined time T1 and longer than the second predetermined time T2 does not cause the pulverization / pressure feeding motor 52 to be broken, but the pulverization / pressure feeding motor 52 has a load. This shows the state. In addition, the fact that there is a stop time in a time region shorter than the second predetermined time T2 indicates a state in which a load that may damage the crushing and pressure feeding motor 52 is applied to the crushing and pressure feeding motor 52.

  As described above, in the flushing pressure-fed toilet 1 of the present embodiment, as a condition for notifying a crushing abnormality or a pumping abnormality, first, a foreign substance such as a paper diaper is shortened due to mixing in the crushing unit 60. By adopting that the stop time t is within a predetermined time, it is assumed that either a pulverization abnormality or a pumping abnormality has occurred based on the stop time t. In addition, based on the water level L in the storage tank 51 that rises due to the clogging of the pressure feeding pipe 53, if the water level L is equal to or higher than a predetermined level, the pressure is abnormal. Thus, it is determined and notified whether the abnormality that has occurred is a pulverization abnormality or a pumping abnormality. With such a configuration, it is possible to detect and discriminate abnormalities occurring in the flushing and pressure-fitting toilet 1 regardless of the load amount of the crushing and pressure-feeding motor 52. Therefore, it is possible to accurately detect crushing and pressure abnormalities. It becomes possible.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS.
FIG. 7 is a main flowchart illustrating a specific example of the operation of the flushing and toilet bowl according to the second embodiment of the present invention. FIG. 8 is a sub-flowchart illustrating a specific example of the operation of the flushing and toilet bowl according to the second embodiment of the present invention.
In the following description, the contents common to the first embodiment of the present invention described above will be appropriately omitted using the same reference numerals and similar names as those in the first embodiment. The first embodiment and the second condition are different in the flushing and feeding toilet according to the present embodiment in comparison with the first embodiment.

  As shown in FIG. 7, the main flowchart illustrating a specific example of the operation of the flush pressure-fed toilet according to the second embodiment is a main flowchart illustrating a specific example of the operation of the flush-fitted toilet according to the first embodiment. It is the same.

  First, when the flush flushing toilet 1 is turned on (step S301), the flush flush toilet 1A enters a standby mode (step S302). At this time, the toilet body 20 is in a state in which sealed water is formed by the stored water 24, and the water level in the storage tank 51 is the standby water level L2 (see FIG. 2). Further, the control device 90A lights the first state display means 55a of the notification unit 55 in green (see FIG. 4). This notifies the user and the operator that the flush toilet 1A is turned on. Note that when the power is turned off at this time, the flushing pressure toilet 1A ends its operation. In addition, the flush pressure-fed toilet according to the second embodiment has the same number as the flush-flush toilet 1 according to the first embodiment shown in FIG.

  Subsequently, when the washing operation switch of the remote control 98 for flowing the toilet body 20 is turned on by the user (step S303), the control device 90A receives the toilet washing signal from the remote control 98, and the water supply valve 4a is opened. Thus, a water supply valve drive signal is output to the water supply valve 4a. Thereby, wash water is supplied to the toilet bowl main body 20, and the toilet bowl main body 20 is wash | cleaned (step S304). At this time, solids and sewage in the bowl portion 21 of the toilet body 20 pass through the drainage channel 23 and are discharged into the grinding chamber 64 of the storage tank 51. The toilet body 20 is washed by supplying 5.5 L of water to the toilet body 20. In addition, a reservoir 24 is formed and sealed in the drainage channel 23.

Subsequently, the control device 90 </ b> A outputs a motor drive start signal to the crushing and pressure feeding motor 52. As a result, the crushing and pressure-feeding motor 52 starts to drive, and the pulsator 61 and the impeller 70 start to rotate. When the pulsator 61 and the impeller 70 are rotationally driven, the solid matter trapped in the pulverization chamber 64 is pulverized, and the solid matter and sewage that have flowed out from the pulverization chamber 64 to the outside of the pulverization chamber 64 in the storage tank 51. The pressure feeding is executed (step S305).
Subsequently, when 25 seconds have elapsed from the start of driving of the crushing and pressure-feeding motor 52, the process proceeds to step S401 shown in FIG. 8 (step S306). The control device 90A turns on the second state display means 55b in red for 25 seconds from the start of driving of the crushing and pressure feeding motor 52 (see FIG. 4). Thereby, a user and an operator are alert | reported that 1 A of flush pressure-feed type toilet bowls are performing pulverization pumping operation.

  When 25 seconds have elapsed from the start of driving of the crushing and pressure feeding motor 52, the control device 90A outputs a motor drive stop signal to the crushing and pressure feeding motor 52 (step S401). Subsequently, the control device 90A starts measurement by the stop time measuring unit 91b (step S402). Subsequently, the control device 90A determines whether or not the rotational speed A of the crushing and pressure feeding motor 52 is zero (step S403). When the rotational speed A is not zero (step S403: NO), the measurement by the stop time measuring means 91b is continued until the rotational speed A of the crushing and pressure feeding motor 52 becomes zero (step S403). If the rotational speed A is zero (step S403: YES), the measurement by the stop time measuring means 91b is terminated (step S404). Thus, the stop time t is measured by the process from step S402 to step S404. The stop time t indicates the time from when the control device 90A outputs a motor drive stop signal to the crushing and pressure feeding motor 52 until the crushing and pressure feeding motor 52 stops.

  Next, the control device 90A determines whether or not the stop time t is longer than the first predetermined time T1 (step S405). Here, the “first predetermined time T1” means that the pulverization is performed after the motor drive stop signal is output to the pulverization / pumping motor 52 obtained when the flushing / pumping toilet 1A according to the present embodiment is installed on the site. This time is set based on the time T0 (drainage environment measurement value) until the pumping motor 52 stops.

  When the stop time t is longer than the first predetermined time T1 (step S405: YES), the control device 90A determines that there is no abnormality in the operation of the flush flush toilet 1 and resets the stop time t ( Step S406). If it is determined that there is no abnormality in the operation of the flushing pressure toilet 1A, the process proceeds to the above-described step S302 shown in FIG. 7 (step S407).

  On the other hand, when the stop time t is equal to or shorter than the first predetermined time T1 (step S405: NO), it is determined whether or not the stop time t is longer than the second predetermined time T2 (step S408). Here, the “second predetermined time T2” is a time shorter than the first predetermined time T1, and after the motor driving stop signal is output to the crushing and pressure feeding motor 52, the crushing and pressure feeding motor 52 stops. It is the time set based on time T0 (drainage environment measurement value).

  When the stop time t is longer than the second predetermined time T2 (step S408: YES), it is determined whether or not the water level L in the storage tank 51 is equal to or higher than the determination water level L1 (step S409). When the water level L in the storage tank 51 is equal to or higher than the determination water level L1 (step S409: YES), the control device 90A determines that a pumping abnormality has occurred, and notifies the notification unit 55 that the pumping abnormality has occurred. (Step S410). At this time, the flush flushing toilet 1A according to the present embodiment alerts the maintenance to be performed by notifying that the abnormality in the pressure feeding has occurred by the notification unit 55, but is in a usable state. In the next step, the process returns to the above-described step S302 shown in FIG. 7 (step S411).

  Note that the control device 90A causes the first state display means 55a and the second state display means 55b to blink simultaneously in red until no abnormal pumping state is detected (see FIG. 4). Further, the control device 90A repeatedly outputs the voice “The pressure abnormality has been detected. Please contact XX” repeatedly by the voice output means 55d. As a result, the user or the operator is informed that a pressure feeding abnormality has been detected.

  On the other hand, when the water level L in the storage tank 51 is less than the determination water level L1 (step S409: NO), the control device 90 determines that a crushing abnormality has occurred, and notifies that the crushing abnormality has occurred. (Step S412). At this time, the flush flushing toilet 1A according to the present embodiment alerts the maintenance to be performed by notifying the occurrence of pulverization abnormality by the notification unit 55, but is in a usable state. In the next step, the process returns to the above-described step S302 shown in FIG. 7 (step S411).

  The control device 90A causes the second state display means 55b and the third state display means 55c to blink simultaneously in red until no abnormal grinding state is detected (see FIG. 4). Further, the control device 90A repeatedly outputs the sound “The pulverization abnormality has been detected. Please clean the pulverization chamber after turning off the product” five times by the audio output means 55d. As a result, the user or the operator is notified that the crushing abnormality has been detected.

  When the stop time t is equal to or shorter than the second predetermined time T2 (step S408: NO), the control device 90A has an abnormality that may cause water to overflow from the toilet body 20 if the use is continued (hereinafter, “operation” for convenience of explanation). It is determined that the operation prohibition abnormality has occurred, and the notification unit 55 notifies that the operation prohibition abnormality has occurred (step S413). Subsequently, the control device 90 prohibits driving of the crushing and pressure-feeding motor 52 and the water supply device 4 (step S414). Then, the toilet bowl cleaning operation is terminated.

  Note that the control device 90A causes the first state display unit 55a, the second state display unit 55b, and the third state display unit 55c to blink simultaneously in red until no operation prohibition abnormal state is detected (see FIG. 4). Furthermore, the control device 90 repeatedly outputs the voice “The product has an abnormality. The product is in an unusable state. This notifies the user or operator that an operation prohibition abnormality has been detected and that the flushing toilet 1 has been disabled.

  As described above, in the process of step S413, the flushing pressure toilet 1A according to the present embodiment notifies the operator 55 that the pumping abnormality has occurred, thereby prompting attention to perform maintenance, and in step S414. In the processing, the pulverization and pressure feeding motor 52 and the water supply device 4 are prohibited from being used, thereby making the state unusable. Thereby, it is possible to prevent the water from overflowing from the toilet body 20 by using the flushing / pumping toilet 1A while an abnormality has occurred in the flushing / pushing toilet 1A.

  As described above, in the flushing pressure-fed toilet 1 according to this embodiment, when the first condition is satisfied, the notification unit 55 notifies the pulverization abnormality, and when the second condition is satisfied, the notification unit 55 causes the pumping abnormality.

Further, the second condition is that the stop time t is shorter than the first predetermined time T1, the stop time t is longer than the second predetermined time T2, and the water level in the storage tank 51 is determined as the determination water level L1. That is all. Thereby, the notification unit 55 is detected by the water level detection sensor 80 in a range in which the stop time measured by the stop time measuring unit 91b is shorter than the first predetermined time T1 and longer than the second predetermined time T2. Since the water level is equal to or higher than the determination water level L1, it is not necessary to make a complicated determination, and it is possible to accurately notify the pumping abnormality and the pulverization abnormality with a simple configuration. Maintenance can be encouraged before it can no longer be used.

  Further, in the flush flushing toilet 1A according to the present embodiment, the control device 90A measures the measurement value measured when the flush flush toilet is installed as the drainage environment measurement value, and the first predetermined time and the second Set a predetermined time.
