The toilet seat 12 is arranged along the opening of the toilet body 11, and has a substantially annular shape and a flat upper surface. The toilet lid 13 is a lid that covers the openings of the toilet seat 12 and the toilet body 11 so as to be openable and closable, and is hinged to the upper part of the functional portion 14.

The functional unit 14 is arranged above the toilet body 11, and is a portion in which functional parts for operating each part of the toilet device 10 such as an opening / closing mechanism for the toilet seat 12 and the toilet lid 13 and a cleaning mechanism for the user's buttocks are arranged. .. A pressure sensor 5 and an electrostatic sensor 3, which will be described later, are connected to the functional unit 14, and a control unit 7 and a notification unit 81 for controlling the first valve 61, the second valve 41, and the flush valve 23 are arranged.

The toilet bowl clogging clearing device 1 is provided separately from the toilet bowl device 10 and is installed in contact with the wall 9. The toilet bowl clogging clearing device 1 includes a cleaning pipe 2, a drain pipe 4, a connection part 6, a first valve 61, a second valve 41, a flush valve 23, a pressure sensor 5, and a static water level detection unit. It has an electric sensor 3 and a control unit 7.

One end of the cleaning pipe 2 is connected to the back side of the toilet bowl body 11, and the other end penetrates the wall 9 and is connected to the water supply source inside the wall 9. The washing pipe 2 supplies washing water from the water supply source into the bowl portion 110 of the toilet bowl main body 11. As shown in FIG. 1, the cleaning pipe 2 has a horizontal portion 21 extending in a substantially horizontal direction from the back surface side of the toilet bowl main body 11, and an extension portion 22 bent from the horizontal portion 21 and extending in the vertical direction.

The horizontal portion 21 is a portion in which one end of the pipe of the cleaning pipe 2 is connected to the toilet bowl main body 11 and extends horizontally from the connected portion to the rear of the toilet bowl main body 11. The lower end surface of the horizontal portion 21 is arranged at least at a position lower than the upper surface 11a of the toilet bowl main body 11. Preferably, the upper end surface of the horizontal portion 21 is also arranged at a position lower than the upper surface 11a of the toilet bowl main body 11.

The extension portion 22 extends upward from an end portion of the horizontal portion 21 that is not connected to the toilet bowl body 11. The extension portion 22 may extend in any direction or may be bent as long as the washing water can be supplied from the water supply source to the toilet bowl main body 11 by using a pump or the like.

The drainage pipe 4 is provided separately from the toilet bowl device 10 and can be attached to and detached from the toilet bowl main body 11. The drain pipe 4 is connected to the rear of the toilet bowl device 10. The drain pipe 4 is connected to the drain port 111 of the toilet bowl main body 11 and is connected to a sewer pipe (not shown). The drain pipe 4 drains sewage from the toilet bowl main body 11.

The connection portion 6 is a pipe that connects the cleaning pipe 2 and the drain pipe 4, and one end is connected to the cleaning pipe 2 and the other end is connected to the drain pipe 4. The connecting portion 6 branches from the lower end of the extension portion 22 of the cleaning pipe 2 and is connected to the upstream side of the drain pipe 4.

The first valve 61 is arranged at the connection portion 6. The first valve 61 is a three-way valve, and switches between a flow path for flowing the washing water from the washing pipe 2 to the toilet body 11 side and a flow path for flowing the washing water from the washing pipe 2 to the drain pipe 4 via the connecting portion 6. It is a switching valve. The first valve 61 is arranged in the vicinity of the end portion of the connecting portion 6 connected to the cleaning pipe 2.

The second valve 41 is a drain valve provided in the drain pipe 4 and closes or opens the drain passage of the drain pipe 4 to flow to the sewer pipe. The second valve 41 is formed of a circular lid having a diameter substantially the same as the diameter of the drain pipe 4, and is hinged to open and close.

The flush valve 23 is provided in the cleaning pipe 2 and is attached to the extension portion 22 upstream of the first valve 61. The flash valve 23 is electrically connected to the electrostatic sensor 3 described later. The flush valve 23 is composed of a water stop valve for stopping the washing water flowing through the washing pipe 2, an on-off valve for discharging and stopping the washing water, and a check valve for preventing the backflow of the washing water (all not shown). NS. The flush valve 23 normally discharges and stops the washing water discharged from the washing pipe 2 to the bowl portion 110 of the toilet bowl main body 11 when the toilet bowl main body 11 is not clogged. As will be described below, when the toilet bowl body 11 is clogged, the flush valve 23 is opened to supply the cleaning water from the cleaning pipe 2 to the drain pipe 4.

The cleaning pipe 2 constitutes a unit 24 that is separate from each of the drain pipe 4 and the flush valve 23 and can be connected to each other. The unit 24 is assembled and transported as one set. The unit 24 is arranged on the side opposite to the toilet bowl device 10 with the wall 9 in between.

The pressure sensor 5 is attached to the drain pipe 4 and detects the pressure inside the drain pipe 4. The pressure sensor 5 is a gauge type sensor in which a diaphragm is arranged in the drain pipe 4. The pressure sensor 5 is preferably arranged at a position away from the connection portion 6.

The electrostatic sensor 3 is a capacitance sensor that detects the water level from the change in capacitance between the electrode for the sensor and the GND electrode. When the water level of the bowl portion 110 of the toilet bowl body 11 rises, the water level of the cleaning pipe 2 leading to the bowl portion 110 rises. When the water level of the cleaning pipe 2 rises, the capacitance between the sensor electrode and the GND electrode changes. By detecting the change in the capacitance, the electrostatic sensor 3 detects the change in the water level of the cleaning pipe 2. Based on the detection result of the electrostatic sensor 3, the control unit 7, which will be described later, determines whether or not the toilet bowl device 10 is clogged. The electrostatic sensor 3 has a pair of electrodes 31 and 32 and a processing unit 33. As shown in FIG. 1, one of the pair of electrodes 31 and 32, the first electrode 31, is composed of a metal cleaning tube 2. The cleaning tube 2 is connected to a GND circuit and serves as a GND electrode. Of the pair of electrodes 31 and 32, the other second electrode 32 is connected to the horizontal portion 21 of the cleaning pipe 2. The second electrode 32 is an electrode for a sensor.

As shown in FIG. 2A, the second electrode 32 is configured with an insulator 321 covering the periphery of the metal electrode body 320. The second electrode 32 is separated from the cleaning tube 2 which is the first electrode 31 by an insulator 321 so that a change in capacitance can be detected between the two electrodes. In a normal state where the washing water stored in the bowl portion 110 of the toilet bowl main body 11 is at a normal water level, the washing water is present on the lower side of the horizontal portion 21 of the washing pipe 2. In the normal state, the washing water is not in contact with the second electrode 32.

When the flush valve 23 is opened to wash the toilet bowl body 11 and the washing water is discharged, or when the toilet bowl body 11 is clogged and the water level of the bowl portion 110 rises, the water in the washing pipe 2 is discharged. When the water is full, the second electrode 32 is immersed in water.

The processing unit 33 is a circuit that measures the capacitances of the first electrode 31 and the second electrode 32 and converts them into digital values. The processing unit 33 is arranged in the functional unit 14 and is connected to the control unit 7 that controls the operation of the toilet bowl device 10.

The control unit 7 is arranged inside the functional unit 14 and is electrically connected to the pressure sensor 5, the electrostatic sensor 3, the first valve 61, the second valve 41, and the flush valve 23, and automatically opens and closes these. Control to do.

The clogging clearing control of the toilet bowl clogging clearing device 1 of the present embodiment will be described with reference to FIGS. 3 to 7. In FIGS. 3 to 7, the toilet seat 12, the toilet lid 13, the functional unit 14, the control unit 7 in the functional unit 14, and the like in the toilet device 10 are not shown.

FIG. 3 shows normal operation without clogging. Normally, the flush valve 23 is opened to supply the cleaning water to the toilet bowl device 10 from an external water supply source (not shown) through the cleaning pipe 2. The route through which the cleaning water is supplied from the cleaning pipe 2 to the toilet bowl main body 11 is the water supply channel. When there is no clogging, the used sewage is drained from the drain pipe 4 to the sewage. The flow path through which sewage flows through the drainage pipe 4 is a drainage channel.

As shown in FIG. 4, when the drain port 111 is clogged with the foreign matter F, the water level of the bowl portion 110 rises. When the water level of the bowl portion 110 rises, the water level of the cleaning pipe 2 rises, and the electrostatic sensor 3 detects the rise of the water level. That is, the electrostatic sensor 3 detects that the toilet bowl device 10 is clogged due to the rise in the water level of the cleaning pipe 2. More specifically, when the electrostatic sensor 3 detects that the water level in the cleaning pipe 2 is higher than the preset water level threshold value, the electrostatic sensor 3 outputs a signal to the control unit 7 that the threshold value has been exceeded. The control unit 7 receives the signal from the electrostatic sensor 3 and starts the clogging clearing control of the toilet bowl clogging clearing device 1. At the same time that the control unit 7 starts the clogging clearing control, the pressure sensor 5 is energized to monitor the pressure in the drain pipe 3.

As shown in FIG. 5, when the toilet bowl device 10 is clogged, the control unit 7 opens the flush valve 23 to supply the flush valve 23 from the cleaning pipe 2 to the drain pipe 4. The control unit 7 switches the water supply path for the wash water by the first valve 61 provided in the connection part 6, and causes the wash water to flow to the drain pipe 4. When the flush valve 23 is opened, the washing water passes through the connection portion 6 and is supplied to the drain pipe 4. The air in the drain pipe 4 is partially discharged from the drain pipe 4 while the washing water is supplied from the connection portion 6. The control unit 7 closes the second valve 41 later than the first valve 61. At this time, since the cleaning water of the cleaning pipe 2 flows to the drain pipe 4, the water level of the horizontal portion 21 drops, so that the detection state of the electrostatic sensor 3 is released.

As shown in FIG. 6, from the state of FIG. 5, the control unit 7 opens the flush valve 23 and supplies the washing water to the drain pipe 4 via the connection unit 6. As a result, the pressure in the drain pipe 4 rises. The pressure in the drain pipe 4 increases between the clogged foreign matter F in the drainage port 111 and the second valve 41, and pushes the foreign matter F back toward the bowl portion 110 to clear the clogging. When the blockage is cleared, the pressure drops. In the pressure sensor 5, the threshold value of the boundary between the width of change in the pressure in the drain pipe 4 and the width of change in the normal operation range and the large width in which the clogging is considered to be cleared is set in advance. .. Then, when the pressure in the drain pipe 4 drops by a width exceeding the preset change width threshold value during the pressure monitoring by the pressure sensor 5, the control unit 7 exceeds the predetermined change width threshold value. Outputs a signal that the pressure has dropped. When the pressure drops beyond a predetermined range of change, the control unit 7 determines that the clogging has been cleared. If the pressure does not drop and the pressure exceeds a certain reference, the pressure sensor 5 transmits a signal to the effect that the reference has been exceeded to the control unit 7. If the pressure exceeds the standard and the pressure is too high, the control unit 7 stops the supply of wash water for safety.

As shown in FIG. 7, after receiving a signal from the pressure sensor 5 that the pressure has dropped, the control unit 7 opens the second valve 41 while opening the flush valve 23. Then, at least a part of the clogged foreign matter F is drained. Since the second valve 41 is closed later than the first valve 61, the air in the drain pipe 4 escapes after switching the water supply channel, so that the sewage can be drained smoothly. When the foreign matter F is drained, the pressure in the drain pipe 4 drops, and the supply of wash water from the flush valve 23 continues. Therefore, after transmitting a signal indicating that the pressure has dropped, the pressure sensor 5 transmits a signal to that effect to the control unit 7 when the pressure in the drain pipe 4 exceeds a preset value. The control unit 7 determines that the pressure in the drain pipe 4 has recovered, and stops the supply of the washing water.

When the foreign matter F is discharged and the pressure in the drain pipe 4 is restored, the state of FIG. 3 is restored, the first valve 61 of the connection portion 6 is closed, the flush valve 23 is opened, and the toilet bowl is opened from the horizontal portion 21 of the cleaning pipe 2. Washing water is supplied to the main body 11 and the toilet bowl is washed once during normal operation. If the electrostatic sensor 3 does not detect an abnormality in the water level after the execution, the clogging clearing control ends. If the clogging is not completely cleared and the water level detected by the electrostatic sensor 3 is higher than a predetermined threshold value, the clogging clearing control is performed again from the state of FIG.

As shown in FIG. 1, the notification unit 81 is arranged inside the functional unit 14 and is electrically connected to the control unit 7. The notification unit 81 is configured to be able to transmit a signal to the management unit 82 outside the toilet bowl device 10. When the control unit 7 determines that the toilet bowl body 11 is clogged, the notification unit 81 receives a signal output from the control unit 7 that the toilet bowl body 11 is clogged, and receives a signal that the toilet bowl body 11 is clogged. Notify the external management unit 82 that manages the situation of 10 that a blockage has occurred.

The management unit 82 is a system for maintaining and managing the toilet bowl device 10, and receives a signal indicating that the managed toilet bowl device 10 is clogged. Upon receiving the information, the administrator of the management unit 82 monitors the state of the toilet bowl device 10 and the control of the clogging clearing device 1, and performs maintenance and the like when necessary.

According to this embodiment, the following effects are achieved. The toilet bowl clogging clearing device 1 is connected to a washing pipe 2 that supplies washing water to the toilet bowl device 10, a drain pipe 4 that drains sewage from the toilet bowl device 10, and a connection portion 6 that connects the washing pipe 2 and the drain pipe 4.
