Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a flap valve opening mechanism at the outlet of a flush toilet, a so-called simple flush toilet, which cleans and discharges waste from the toilet bowl with a small amount of water. It is related to.

[Prior Art] Typical flap valve opening/closing mechanisms for conventional simple flush toilets include those shown in FIG. 6 and FIG. 8, for example. The simple flush toilet shown in Fig. 6 uses the force of the drop between the water level of the flush water 2 in the water tank 1 and the discharge nozzle 4 of the toilet bowl 3 to circulate the flush water 2 into the toilet bowl 3 to wash and discharge waste. It is. A flap valve 6 is pivotally connected to the outlet 5 at the bottom of the toilet bowl 3 by a pivot shaft 7 so as to be openable and closable. energized to close the flap valve 6. This is a gravity rM idle method, and when dirt is placed on the flap valve 6 during urination, or when washing water 2 is accumulated during washing, the weight changes from the state shown in Fig. 7 (a) to Fig. 7 (b).
), the flap valve 6 opens and dirt and wash water 2 are removed.
is ejected and then closed again. In addition, in the simple flush toilet shown in FIG. 8, when the gouya 7 hum 11 of the gouya 7 ram pump 10 for discharging flush water is pushed by an external force, the wash water 2 in the gouya 7 ram pump 10 is pressurized and a constant amount of flush water 5 is produced. The cleaning method is such that the liquid is discharged from the discharge nozzle 2. An arm 12 extending from a pivot shaft 7 of the flap valve 6 and a pedal 13 are connected by a valve link 14, and biased by a flap valve spring in a direction in which the flap valve 6 is engaged. Is this manual control? ! When washing after using the m method, by manually operating the pedal 13 (by stepping on the foot), the washing water 2 is discharged and the 9th water is simultaneously discharged.
From the state shown in FIG. 9(a) to the state shown in FIG. 9(b), the flap valve 6 changes to rM! Then, the filth and wash water 2 are discharged, and the flap valve 6 is closed again. If only the cleaning water discharge operation is performed, the cleaning water 2 will be discharged by the pressing force that closes the flap valve 6.
can be stored at the bottom of the toilet bowl 3.

[Problem to be Solved by the Invention 1] In the former case of the above-mentioned conventional example, no special operation is required because it automatically opens and closes depending on the weight of the filth or the washing water 2. Since the flap valve 6 opens and closes automatically when the flap valve 6 is opened and closed, the force pressing the flap valve 6 against the discharge port 5 is weak, and the flushing water 2 cannot be stored at the bottom of the toilet bowl 3. Since it can only be used after the toilet bowl 3 and flap valve 9 are filled, dirt tends to accumulate on the toilet bowl 3 and flap valve 9.

In addition, in the latter of the above conventional examples, the wash water 2 can be stored in the toilet bowl 3, and the adhesion of dirt to the toilet bowl 3 and the flap valve 6 can be extremely reduced. This requires the effort and effort of operating the pedal 13 with the same force.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to be able to collect flush water in the toilet bowl using the manual forced opening/closing method described above, and to prevent the flushing water from flowing into the toilet bowl or flap valve. To provide a flap valve opening/closing If groove in a simple flush toilet, which allows the flap valve to be opened easily without the conventional pedal operation while taking advantage of the feature of greatly reducing the adhesion of filth.

The motor 16 is operated by an operation switch section 17 that is operated by remote control via remote control #123, and the upper part of the rear of toilet bowl A is equipped with a flap valve 6 that can be opened and closed by remote control. A water tank 1 is arranged, and the water tank 1 has a hand washing section 24.
and a pole tap 25. An over 70-pipe 26 is introduced into the water tank 1 from the bottom of the water tank 1, and a diaphragm pump 10 is installed at the bottom of the toilet bowl A to discharge the overflowing flush water 2 from the water tank 1. The water chamber 27 of the diaphragm pump 10 and the inside of the water tank 1 are communicated through a wash water supply pipe 28. Inside the water tank 1 of the flush water supply pipe 28 is a sia-shaped suction part 29. At the top of the toilet bowl 3 is a discharge nozzle 4, which connects the water chamber 27 of the diaphragm pump 10 and the discharge nozzle 4. It is connected to the nozzle 4 through a cleaning water discharge pipe 30. The diaphragm pump 10 has an interior partitioned into two chambers by a diaphragm 11 to form a water chamber 27 and an air chamber 31. A center plate 32 is attached to the center of the diaphragm 11.
The diaphragm 11 is biased by a diaphragm spring 33 so that the air chamber 31 is bent. The cleaning water supply pipe 28 and the cleaning water discharge pipe 30 of the diaphragm pump 10
A check valve 34 is installed at the connection part with the toilet bowl A, and an air pump 35 for pressurizing the tank and a pressurizing tank 36 for storing pressurized air are installed at the bottom of the toilet bowl A adjacent to the diamond 7 humbump 10. It is arranged. Air sent from the air pump 35 is stored in a pressurized tank 36 via a reverse valve. The pressurized tank 36 and the air chamber 31 of the diamond 7 ram pump 10 are communicated through an air supply pipe, and a switching valve is disposed in this air supply pipe. By switching the switching valve, the ffl's is switched, the pressurized tank 36 and the diaphragm pump 10 are communicated,
The diaphragm pump 10 and the exhaust pipe can be communicated with each other. This switching valve is also operated by the operation switch section 17.

Next, the operation of flushing the toilet bowl 3 after using the toilet will be explained.

In the diaphragm pump 10, since air is normally not supplied to the air chamber 31, the diaphragm 11 is bent by the diaphragm spring 33, and water is sucked from the wash water supply pipe 28 into the water chamber 27. It is filled with cleaning water 2. Now, use the operation switch section 17 to clean the cleaning 1u17a.
