It has a structure that allows water to flow into the toilet bowl by driving it with a manual lever, but since the water pressure in the toilet is applied to the valve, a considerable amount of force is required to operate the manual lever, making it difficult for children and elderly people with weak strength to operate the manual lever. It was difficult to use.

Therefore, as a solution to this drawback, the

regulated by the notch width.

FIG. 4 is a (b) circuit diagram of the energizing means 12 in the conventional example, where 38 is a power source, 39 is a capacitor constituting the first timer, 40 is a charging resistor for the capacitor 39, 41 is a discharging resistor, 42. 43 is an i resistor for reference potential, 44 is a fl comparator, 45 is a pull-anog resistor, 46 is a converter constituting the second timer, 47 is a charging resistor, 48
49 is a diode constituting a discharge path, and 49 is a co/va v −
50 ij 7" Luasub resistor, 61 is a current limiting resistor, 62 is a differential pulse capacitor, 53 is a diode that constitutes the discharge path of the capacitor 62, 64 is a flip-flop, 55 is a pace resistor, 56 is a transistor,
67 is a microresistance that generates electric current II according to the coil current of the motor 8, 58 and 59 are reference potential resistors, 60 is a conoparator, and 61 is a pull-up resistor.

With the configuration shown in FIGS. 1 to 4, when a user sits on the toilet seat 2, the microswitch 10 is turned on and the capacitor 39 is charged via the resistor 40. At this time, the potential at point k is lower than the potential l and a, so the comparator 44 is off, so the potential at point m is higher than the 1st focal potential, and the conoparator 49 is on, so the flip-flop 64 is not set and outputs Q. is maintained at Low, and Tora/Gystaro 6 is also maintained in an off state. When the user finishes using the toilet and stands up from the toilet seat 2, the electric charge on the air conditioner/suction 39 is transferred to the resistor 4.
Since discharge starts via 1 and the pyroelectric potential becomes higher than 1 pyroelectric potential, the conopalator 44 is turned on. Therefore, the capacitor 46 starts charging through the resistor 47, but the conoperator 49 is off. When a certain period of time, for example 3 seconds has passed after standing up from the toilet seat 2, the capacitor 46 is charged and the potential at point m becomes lower than the focal potential at point 1.
The conoparator 49 is turned off. Therefore resistance 50.5
1. Flip-flop 64 via converter/suction 62
is set, transistor 56 is turned on, and motor 66 is turned on.
Fully energize. This bias causes the through shaft 7 to rotate,
The arm 61a is moved from the arm 61a to the arm 61b to open the valve 4 and flush the inside of the toilet bowl. At this time, while the arm 6 is moving from a to b, the current flowing through the motor 8 is small, so the n-point potential is higher than the p-point potential, and the comparator 60i turns on to 1, but when it reaches b, it rotates. The corner regulating bin 24 is the notch 1
When it hits the top of point 9, the motor 8 becomes locked, and at that moment the current of the motor 8 increases rapidly, and the potential at point n becomes p.
The voltage drops below the point potential, the comparator 6o turns off, and the resistor 6
1 through the flip-flop 54. Therefore, output Q is inverted to low, turning off transistor 66 and deenergizing motor 8. The motor 8 is energized while the arm 6 is moving from a to b (about 0.5 seconds).
The moment b is reached and valve 4 is opened by the henchman, the power is automatically deenergized. However, the valve 4 is kept open by the drainage force of the water in the toilet 3, and the toilet bowl 1 continues to be flushed. When most of the water is discharged and the drainage force decreases, the arm 6 returns to the position a due to the weight of the valve 4, and the valve 4 closes to store water in the distern 3 again. After a certain period of time, for example 6 seconds, has elapsed since the user stood up from the toilet seat 2, in other words, 2 seconds after the motor 8 started to be energized, the capacitor 39 will discharge and the pyroelectric potential will reach the level of 1. comparator 44 turns off.

Therefore, capacitor 46 is connected to resistor 46 and diode 48.
, the potential at point m becomes higher than the 1-point level, the comparator is turned on again, and the charge in the capacitor 62 is also discharged via the resistor 51 and diode 53, and everything returns to its original state. It waits for the next use of the toilet seat. Furthermore, if the user wishes to flush the toilet seat 2 while using it, he or she can press the button switch 11 to set the flip-flop 4 and flush the toilet seat 2 at any time in the same manner as with the seat switch. be.

With the above configuration, when the user finishes using the toilet and stands up from the toilet seat, or simply by operating a switch installed in the storage box, the motor and one shaft are electrically energized to rotate and the valve is opened. Since the device is washed with water, it can be easily used even by weak elderly people and children, and it solves the drawbacks of the conventional method, but a new problem has been raised. When using the toilet seat, in other words, Okawa for men and Okawa for women.
Since paper is always used when doing errands, it is necessary to drain all the water in the toilet in order to wash away the paper. It is not necessary to drain all the water inside, and sometimes the purpose can be achieved by just letting a small amount of water flow.In fact, in the conventional manual lever type, all the levers can be moved to the left and right at the same time.For example, if the lever is rotated to the right, There was also a structure in which the valve was fully opened to release all the water in the distern, and when turned to the left, the valve was opened slightly to drain a small amount of water continuously. In this case, since the drainage force is small, the valve does not open all at once, and by keeping the lever turned counterclockwise, a small amount of water and gold can be continuously drained, thereby saving water. Met. However, although the conventional configuration shown in FIGS. 1 to 4 is easier to operate than lever operation, it has the disadvantage that all the water in the cylinder is always drained, resulting in a lot of wasted water. was.

OBJECTS OF THE INVENTION The present invention solves the problems of the prior art, and its overall purpose is to provide a toilet flushing device that is easy to flush and can save water.
