[Configuration of controller 80]
Next, the configuration of the controller 80 as a control device for detecting excrement excreted in the cup member 10 will be described with reference to FIG.
Specifically, the controller 80 has a function of detecting the excrement excreted in the cup member 10 based on the signal detected by the sensor unit 15.

As shown in FIG. 8, the controller 80 includes a processor 81, a storage device 82, an input / output interface 83, a connection unit 84, and a detection circuit 90 as hardware.

The processor 81 is hardware for executing an instruction set described in a program. Then, the processor 81 executes various arithmetic processing based on the programs and data stored in the storage device 82.
Specifically, the processor 81 controls the operation of the blower 41, the pump 63, and the like.

The storage device 82 includes, for example, a memory and a magnetic disk device, stores various programs and data, and also functions as a work memory of the processor 81. The storage device 82 may include an information storage medium such as a flash memory or an optical disc.

The input / output interface 83 communicates with devices such as the blower 41, the pump 63, and the operation unit 34 connected via a signal transmission cable. The input / output interface 83 may be connected to each of the blower 41, the pump 63, and the operation unit 34 by a dedicated communication cable.
The operation unit 34 is provided on the upper portion of the apparatus main body 30, and includes a plurality of buttons and a display unit, and operations of execution and stop of various processes (washing, ventilation, suction, etc.) of the excrement suction apparatus 1 Accept

The connection unit 84 is an interface for communicably connecting to the sensor unit 15. That is, the detection circuit 90 can receive a signal from the sensor unit 15 through the connection unit 84.
Specifically, the connection portion 84 is communicably connected to the sensor portion 15 by connecting to the connector 54A of the signal transmission cable 54 of the cup member 10.
More specifically, the detection circuit 90 is connected to the sensor unit 15 via the first electrode wiring Ca1, the second electrode wiring Ca2, the first ground electrode wiring Cb1, and the second ground electrode 19.
Here, the first electrode wiring Ca1 is a wiring connected to the first electrode 16. The second electrode wiring Ca2 is a wiring connected to the second electrode 18 (second electrode 18a). The first ground electrode wiring Cb1 is a wiring connected to the first ground electrode 17. The second ground electrode wiring Cb2 is a wiring connected to the second ground electrode 19 (second ground electrode 19a).

Here, the first ground electrode wiring Cb1 and the second ground electrode wiring Cb2 are connected to a common ground line in the detection circuit 90.
Then, based on the conduction state between the first electrode 16 and the second electrode 18 of the sensor unit 15 and the ground line to which both the first ground electrode 17 and the second ground electrode 19 connect, the detection circuit 90 performs the cup member 10. Determine the presence or absence of excrement inside.

Specifically, when the detection circuit 90 is in a conductive state in which the first electrode 16 and the first ground electrode 17 are connected by a conductor such as excrement, excrement on the receiving portion 11 a of the cup member 10 It is determined that there is
In addition, when the detection circuit 90 is in a conductive state in which the first electrode 16 and the second ground electrode 19 are connected by a conductor such as excrement, if excrement is present on the receiving portion 11 a of the cup member 10 judge.
In addition, if the detection circuit 90 is in a conductive state in which the second electrode 18 and the second ground electrode 19 are connected by a conductor such as excrement, if excrement is present on the receiving portion 11 a of the cup member 10 judge.
Further, when the detection circuit 90 is in a conductive state in which the second electrode 18 and the first ground electrode 17 are connected by a conductor such as excrement, if excrement is present on the receiving portion 11 a of the cup member 10 judge.

The above-mentioned "conductive state" is a state in which a current of a predetermined value or more flows, for example, between the first electrode (plus electrode) and the second electrode (minus electrode).
Although current flows even when the positive and negative electrodes are connected with washing water as a conductor, the excrement is connected with the excrement as a conductor because salinity is higher than that of washing water (there are many electrolytes). In the case, the electrical conductivity is higher and as a result, the current value is larger. Therefore, by comparing the current value flowing to the first electrode and the second electrode with an appropriate threshold value, it is possible to distinguish whether the one in contact with these electrodes is waste or cleaning water.
Specifically, in the detection circuit 90, the value of the current flowing between any one of the first electrode 16 and the second electrode 18 and any one of the first ground electrode 17 and the second ground electrode 19 is equal to or greater than a predetermined threshold value. In this case, it is determined that there is excrement in the cup member 10. The above-mentioned predetermined threshold may be set in advance based on an experimental result or the like.

Hereinafter, based on FIG. 8, a specific example of the configuration of the detection circuit 90 will be described.
As shown in FIG. 8, the detection circuit 90 includes a sensor circuit 91, a ground circuit 92, a drive signal generation circuit 93, an output signal generation circuit 94, a rectification circuit 95, and a comparison circuit 96.

The sensor circuit 91 is connected to the first electrode wiring Ca1 and the second electrode wiring Ca2 via the connection portion 84. That is, the sensor circuit 91 is connected to the first electrode 16 and the second electrode 18.

The ground circuit 92 is connected to the first ground electrode wiring Cb1 and the second ground electrode wiring Cb2 via the connection portion 84. That is, the ground circuit 92 is connected to the first ground electrode 17 and the second ground electrode 19.
The ground circuit 92 has a ground line (reference potential line), and the first ground electrode line Cb1 and the second ground electrode line Cb2 are connected to a common ground line in the ground circuit 92.

The drive signal generation circuit 93 intermittently outputs a pulse signal at predetermined intervals. The pulse signal output from the drive signal generation circuit 93 is input to the output signal generation circuit 94.

The output signal generation circuit 94 is connected to the sensor circuit 91 and the ground circuit 92. Then, the output signal generation circuit 94 generates a pulse signal input from the drive signal generation circuit 93 by using the plus electrode (the first electrode 16 and the second electrode 18) and the minus electrode (the first ground electrode 17 and the second ground electrode 19). And a detection signal obtained by synthesizing the waveform of the current flowing between the
Thus, the output signal generation circuit 94 functions as an amplifier that amplifies the current flowing between the plus electrode and the minus electrode.

The rectifier circuit 95 rectifies the detection signal (voltage signal) input from the output signal generation circuit 94 and outputs the rectified signal to the comparison circuit.

The comparison circuit 96 compares the detection signal input from the rectification circuit 95 with the threshold voltage and outputs the comparison result. As one example, the comparison circuit 96 outputs a high level signal when the detection signal is larger than the threshold voltage. On the other hand, the comparison circuit 96 outputs a low level signal when the detection signal is lower than the threshold voltage.

When the high level signal is output from the comparison circuit 96, the processor 81 determines that there is excrement in the first cover member 11. On the other hand, when the low level signal is output from the comparison circuit 96, the processor 81 determines that there is no excrement in the first cover member 11.
Then, when it is determined that the excrement is present, the processor 81 operates the blower 41, the pump 63, and the like to perform suction processing of excrement and cleaning processing of the excretory part.

In the above example, the detection circuit 90 detects the presence or absence of the excrement as a conductor by using the current value between the plus electrode and the minus electrode as a detection value, but the detection value is limited to the current value. Absent. For example, as the “detection value”, impedance (resistance value), electrical conductivity, admittance or the like may be used.
