Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the water-saving toilet seat washing apparatus according to the present invention.

Figure 2 shows a water-saving toilet seat washing apparatus according to the present invention, the wire wound on the rotating body (8) of the DC motor (6) is connected to the upper end of the toilet siphon cover (7) of the circuit of the DC motor (6) The amount of opening and closing of the siphon lid 7 is determined by the total amount.

FIG. 3 detects whether the toilet seat 2 and the seat cover 3 are opened and closed, and whether the operator sits on the seat cover 3 so as to determine the rotation amount of the DC motor 6 by the control means as shown in FIG. 6. The installation state of the switch S1 and the pressure sensors S5 and S6 is shown.

More specifically, as shown in (a) and (b) of FIG. 4, the switch S1 is inserted into / detached into the recessed recess 4a of the hinge shaft 4 as the toilet cover 2 is opened or closed. It is supposed to work. That is, as shown in FIG. 4A, since the hinge shaft 4 holds the switch S1 in the open state of the toilet cover 2, the switch S1 remains on, but the toilet cover 2 is closed and the switch is closed. When S2 is inserted into the recessed groove 4a as shown in Fig. 4B, the switch S1 maintains the off state.

The operation according to the use of the toilet thus configured will be described.

First, in the case of a male, that is, the toilet seat cover 2 and the seat cover 3 are both raised to keep the switches S1 and S2 on, and the switches S3 and S4 to the off state, The processor 9 counts the usage time of the toilet seat.

Then, when a predetermined time elapses, driving signals are output to transistors TR2 and TR5 to wash the toilet. Accordingly, the siphon cover 7 is opened by the rotation of the DC motor 6 to store water in the reservoir. The toilet is flushed out as it is discharged through the toilet.

At this time, as the DC motor 6 rotates once, the siphon cover 7 is slightly opened than normal, and only a sufficient amount (6 liters) of water is discharged to wash urine.

Of course, after a predetermined time for washing the toilet seat, the microprocessor 9 again outputs a driving signal to the transistors TR3 and TR4 so that the DC motor 6 is reversely rotated so that the siphon cover 7 is closed. .

Next, in the case of a male or a female, that is, the toilet seat cover 2 maintains the switches S1 and S2, and the seat cover 3 descends to maintain the switches S3 and S4. When the pressure sensors S5 to S8 provided at the bottom of the seat cover 3 are operated, the microprocessor 9 counts the usage time of the toilet seat.

As a result, when a certain period of time (about 2 minutes 30 seconds) has not elapsed, it is determined that urine work has been seen, and the microprocessor 9 outputs driving signals to the transistors TR2 and TR5 to wash the toilet. do.

Accordingly, the siphon cover 7 is opened by the rotation of the DC motor 6, and the water stored in the water tank is discharged through the toilet, and the inside of the toilet is washed. At this time, as the DC motor 6 rotates once, the siphon cover 7 is slightly opened than normal and only a sufficient amount (6 liters) of water for washing urine is discharged.

Of course, as described above, after a predetermined time for washing the toilet seat, the microprocessor 9 again outputs a driving signal to the transistors TR3 and TR4, so that the DC motor 6 is reversely rotated so that the siphon cover 7 Will be closed.

However, when a predetermined time (about 2 minutes 30 seconds) has elapsed, it is determined that the stool is seen, and the microprocessor 9 outputs driving signals to the transistors TR2 and TR5 to wash the toilet. . Accordingly, the siphon cover 7 is opened by the rotation of the DC motor 6, and the water stored in the water tank is discharged through the toilet, and the inside of the toilet is washed.

At this time, as the DC motor 6 rotates two times, the siphon cover 7 is completely opened and a sufficient amount (12 liters) of water is discharged to wash the feces.

Of course, as described above, after a predetermined time for washing the toilet seat, the microprocessor 9 again outputs a driving signal to the transistors TR3 and TR4, so that the DC motor 6 is reversely rotated so that the siphon cover 7 Will be closed.

Here, the microprocessor 9 maintains the initial state by the reset signal input through the reset port. For example, the microprocessor 9 operates the reset switch RESET installed so that the operator is exposed to the outside or the toilet bowl. It is a switching element by a switch driven by the outputs of the two OR gates OR1 (OR2) and AND gate AND and the microprocessor 9 combining the opening and closing states of the cover 2 and the seat cover 3. When a predetermined time elapses after the transistors TR1 and SCR (SCR) are operated and a reset signal is generated from the counter 10 and input to the microprocessor 9, the microprocessor 9 clears everything and initializes the initial state. Return to

Preferably, only one siphon cover has been described so far, but if the length of the wire connecting the rotating body 8 and the siphon cover 7 of the DC motor 6 is different, the two siphon covers 7 may also be used. As described above, the amount of water for washing the toilet seat may be controlled by selectively opening and closing according to the type of urine.

According to the present invention as described above, by adjusting the amount of water used to wash the toilet bowl by classifying the toilet seat according to the opening and closing state of the toilet cover and the seat cover and the position of the operator, there is an effect that can reduce unnecessary water consumption.
