It shows a box.

Hereinafter, the operation according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

6 is a flowchart showing the operation of the automatic drainage device of the toilet according to the present invention. As shown in FIG. 6, when the user turns on the power supply, the microcomputer 60 is connected to the steps N1 and N2 of FIG. 6. Similarly, the input port IP3 and another input port IP4 are examined to detect the drainage time at the time of urine and urine set by the variable resistance VR1 for stool drainage time setting and the variable resistor VR2 for urine drainage time setting. The register is stored in the register, which is an internal temporary storage location.

That is, since the drainage time at the time of urine and urine is the same as the drainage discharged from the water tank 100, the drainage can be arbitrarily selected by using the variable resistance VR1 for setting the stool drainage time and the variable resistance VR2 for setting the urine drainage time. You can adjust it.

And, when the toilet is to see the stool, first, when the toilet seat is seated on the seat 50, the stool detection switch is installed between the seat 50 and the toilet 55 while the seat 50 is pressed down by the pressure ( SW1) is touched on.

At this time, the signal detected by the stool detection switch (SW1) is stored in the internal register through the input port (IP1) of the microcomputer 60, and after finishing the toilet and rises from the seat plate 50, the seat plate 60 contacts It is pushed upward by the restoring action of the opening spring 90, and at the same time, the contact point of the feces detection switch SW1 falls.

That is, when the microcomputer 60 detects an input from the stool detection switch SW1 as shown in step N3 of FIG. 6 and the above action is performed by the toilet, the stool detection switch SW1 has a time difference for a predetermined time. It is determined that the operation is turned on / off, and the predetermined timed stool drainage time is stored in the temporary storage location register as in step N4 of FIG. 6, and then the driving time count is started as in step N7 of FIG. 6.

Subsequently, as shown in step N8 of FIG. 6, the driving signal is output to the driving unit 65 through the output port OP of the microcomputer 60, and the actuator 87 is excited while the heavy excitation current is output from the driving unit 65. By the physical movement of the actuator 87, the link 85 overcomes the tensile force of the link return spring 88 and is connected to the other end of the link 85 while moving in the direction of arrow T in FIGS. 3 and 4. The vertical bar 84 is pulled upward.

At this time, the disk-shaped rubber valve 134 of the normally closed valve 70 is connected to the lower end of the vertical bar 84 is pulled from the valve seat 132 is formed on the bottom surface of the water tank 100 As the drain hole 120 is opened, water flows into the toilet 55 to drain.

Thereafter, the microcomputer 60 determines whether the time state value has a value equal to or greater than the register value storing the drain time value when the credit value is stored as shown in step N9 of FIG. 6, and the determination result has a negative value. Next, the process returns to step N7 of FIG. 6 to repeat each step until it has a positive value.

In the case of having the positive value in step N9 by repeating the above process, the microcomputer 60 stops the drive signal output through the output port OP as in step N10 of FIG. 6 and outputs a stop signal to drive unit 65. The excitation current flowing in the actuator 87 is interrupted through and branches to step N1 of FIG. 6.

At this time, the actuator 87 loses the force and at the same time, the link 85 is pulled by the tension of the link returning spring 88, and moves in the direction of arrow B in the accompanying drawings. It stops while being caught by 86, the disk-shaped rubber valve 134 is pushed toward the drain port 120 by the water pressure leads to the loose vertical bar 84 and close the drain port 120.

On the other hand, when the toilet urinates and drains the urine is touched on the urine detection switch (SW2) installed in the control box 150, the signal through the input port (IP2) of the microcomputer 60 The microcomputer 60 detects an input from the urine detection switch SW2 at all times as in step N5 of FIG. 6, and when the above action is performed by the toilet, the urine detection switch SW2. ) Is determined to be on, and the pre-set urine drainage time is stored in the temporary memory register as shown in step N6 of FIG. 6, and then the driving time count is started as in step N7 of FIG. 6.

Thereafter, as shown in step N8 of FIG. 6, the driving signal is output to the driving unit 65 through the output port OP of the microcomputer 60, and the amplified excitation current is output from the driving unit 65 to excite the actuator 87. By the physical movement of the actuator 87, the link 85 overcomes the tension of the link returning spring 88 and moves in the direction of the arrow T in FIGS. 3 and 4, and the other end of the link 85 Pull the vertical bar 84 connected to the upper side.

At this time, the disk-shaped rubber valve 134 of the normally closed valve 70 is connected to the lower end of the vertical bar 84 is pulled from the valve seat 132 is formed on the bottom surface of the water tank 100 As the drain hole 120 is opened, water flows into the toilet 55 to drain.

Thereafter, as shown in step N9 of FIG. 6, the microcomputer 60 determines whether the time count value is greater than or equal to the register value storing the drainage time value when urine, and the determination result has a negative value. Next, the process returns to step N7 of FIG. 6 to repeat each step until it has a positive value.

In the case of having a positive value in step N9 by repeating the above process, the microcomputer 60 stops the driving signal output through the output port OP as in step N10 of FIG. 6 and outputs a stop signal to drive unit 65. The excitation current flowing in the actuator 87 is interrupted through and branches to step N1 of FIG. 6.

At this time, the actuator 87 loses the force and at the same time, the link 85 is pulled by the tension of the link return spring 88 and moves in the direction of arrow B in the true drawing of FIGS. 3 and 4, and the stopper for limiting the lowered position Stopped by the 86, the disk-shaped rubber valve 134 is pushed toward the drain 120 by the water pressure to close the drain 120 to lead the loose vertical bar 84.

As described above, the present invention is configured to automatically drain the water required for stool drainage by automatically detecting the sitting and rising of the seat when the stool looks at the stool. Since it is configured to press a separate switch that can drain less water, there is also an effect to protect the water resources.
