The drain section 2S and the drain section 2S are installed in the opening 7.

Further, the drive guard structure part B includes a solenoid in the operation case /lI-, a solenoid rod shaft 27 inserted into the solenoid so as to be able to appear and retract freely, and when the solenoid rod shaft 27 is energized by the solenoid J7, the solenoid rod shaft 27 is It moves further into the rod shaft, and at that time, the output shaft of the motor MT, the gear 2 at the tip of the 2
g and the operating whistle part/ll- are separated by a partition plate 30 into two small chambers 3! ;a.

The solenoid rod shaft 27 in the small chamber 3jta on the motor MT side separated by JtbK is fixed to the gear 29, and the solenoid rod shaft 27 is fixed to the other small chamber 3jbK via the spring 3. Normally, when the solenoid excitation signal is not input, the gear 32 meshes with the gear 33 provided at the end of the lever shaft 3 of the manual lever/3, as shown by the dotted line in the drawing, and the solenoid rod shaft 27 is rotated by the motor MT and the manual lever/3, the solenoid rod shaft,
Hook hanging holes 37a, 37b, 37 are installed through the tip of the swinging lever 37 so that the swinging lever 37 connected at right angles to the end of the swinging lever 37 moves upward to an appropriate position.

! By selecting the connecting position of the hook 3 relative to ;), the drainage control valve 22 can be freely adjusted and connected so that the drainage control valve 22 can be optimally swung up and down by the up and down movement of the swing lever 37, and the control from the drive control circuit section A can be performed. The drainage control valve 2.2 is made vertically swingable by a signal or by a manual lever 13.

Since the device of the present invention is constructed as described above, the operating whistle section/
Photosensors for defecation and urination installed at ≠ //,
When you bring your hand, etc. in front of /2, the light emitting diode LBD+
, LKD+' is reflected by a hand, etc., and the reflected light is transmitted to the phototransistor FTr1. The detected signals from the phototransistors FTr+ and FTr+' are input to FTr1' and compared with a preset reference value using a comparator circuit ≠, ≠'. If the signal is greater than the reference value, it is a Schmitt switching circuit! ,! ;' and outputs a switching signal from the Schmitt switching circuits j and 3' to operate the transistors Tr+ and Tr+', thereby connecting the S side of the flip-flops P''F+ and Lt'F+'.
Taking the opportunity of sending No. t14, the flip-flop FB

From the output O side, there is a diode D+, and the peak is a photodiode T.
JK]) 2, 'LEDs are also conductive at the same time and light is transmitted to the respective phototransistors FTr2. At the same time as turning on FTrs, the coil of solenoid 2B, 24a, and the coil MTa of motor MT are excited and turned ON to operate the drive mechanism section B, while the flip-flops FF+, F'F+'
The signal output from the output side is sent to the timer circuit:

demagnetize the excitation. The operating circuits XI and X2 constitute a part of the urination direction drive control circuit and the defecation direction drive control circuit, respectively, and the urination direction operation circuit X1 transmits the signal output from the 1- side of the flip-flop FFI to the transistor of the timer circuit section. 1 is input to the base of Trs, and is input to the R side of the flip-flop circuit via the timer circuit E.
In contrast, in the toilet operation circuit x2, the signal output from the 〒 side of the flip-flop FF+' is input to the pace of the transistor Tr2 of the timer circuit E.
After that, like the urination direction operation circuit xl, flip-flop F
It is set so that it takes about 5 seconds to input 1 to the R side of F+'.

In other words, when you bring your hand, etc. close to the photo sensor // for urination, about 21 to 3 J of water flows in about 3 seconds, and about 5 J for urination.
It is set so that about 61 liters of water flows per second. Only L7
However, these "V" are just examples, and depending on the settings of the timer circuit, the water running time and water flow rate can be changed freely, and the water flowing time and water flow level described above can be changed.
but not limited to.

Since the drive control circuit section A operates as described above, the operation of the entire automatic flushing apparatus of the present invention, including the drive mechanism section B and the drainage control valve 22, will be explained when a specified amount of water is stored in the water tank 7. If there is, the flow)/j is in a floating state, the introduction control valve part/7 is closed, and a specified amount of water is stored in the water tank 7. When you bring your hand, etc. close to the photo sensor //, /2 buried in the front of the operating whistle section /lI-, which has a built-in drive control circuit section, the drive control circuit section A operates as described above, and the operation When the solenoid provided in the cylinder part /lI- is excited, the motor MT receives an input signal.
When the solenoid rod shaft 27 rotates at the same time as the gear 29 meshes with the gear 29 at the tip of the shaft, the swinging lever 37 is rotated in both directions around the pivot 3A. Hook hanging hole 37a at the tip.

A hook 3 suspended from one of 37b and 37c and a connecting chain 37F end fixed to the top via a Zen-knot chain 3 are connected to the drainage 1b control valve 22, which is pivoted and swings upwards around 2/. Since the protrusion 20 is disengaged from the outlet, the water stored in the water tank 7 is injected from the outlet through the drain pipe IT into the toilet bowl (not shown). Then, as mentioned above, when a certain period of time, for example about 3 seconds or about 5 seconds, has elapsed, and the solenoid 2 is demagnetized and the input signal to the motor MT is stopped, the solenoid rod shaft 27 is activated. As the swing lever 37 returns to its original position, the drainage control valve 2.2 also returns to the illustrated state in which the protrusion 20 is fitted into the discharge port. on the other hand,
When the water stored in the water tank 7 is used for flushing and the water storage level drops,
As the float /j descends according to the water storage level, the introduction control valve part /7 opens and the water flowing in from the water conduit g is directed diagonally downward onto the top cover of the water tank 7 via the pipe connected to the connection port /B. The water is ejected for washing hands, and falls into the water tank 7 from the opening 1 at the bottom of the funnel-shaped part of the chick, and as the water storage surface rises, so does the float /j. “Accordingly,” ascended two times;
When the predetermined water storage level is reached, the introduction control valve section/7 is closed and the water supply to the water tank 7 is stopped.

In fact, the device of the present invention is provided with a manual lever /3 on the assumption that the photo sensors // and /2 become temporarily unusable due to a power outage or other unforeseen accident. That is, in the operation cylinder part /≠, when the solenoid 2B is not energized, the gear 32 meshes with the gear 33 of the manual lever /3 as shown by the imaginary line due to the elastic force of the spring 3/.
When the manual lever 3 is swung left and right in accordance with the use for defecating and urinating, as in the conventional device, when the solenoid rod shaft 27 also rotates in accordance with the rotation of the gear 3.2, the oscillating lever 37 moves upward. The process described above allows water to flow.

As described above, in the present invention, the lever,
The child can be washed with water without directly touching cocks, strings, push buttons, etc., and the amount used each time can be set to a certain level according to the direction of defecation and urination without any individual differences. .

It relieves the discomfort of directly touching cocks, strings, push buttons, etc., and is effective in preventing infections at the source, especially in hospitals and restrooms used by a large number of people. It has excellent effects not found in conventional devices, such as being able to use the toilet.
