Description

[Detailed Description of the Invention] [Industrial Application Field 1] The present invention relates to a mechanism for discharging flush water in a so-called simple flush toilet, which is a flush toilet bowl that uses a small amount of water to clean and discharge waste from the toilet bowl. .

[Prior Art 1] Typical conventional wash water discharge mechanisms for simple flush toilets include those shown in FIG. 6 and FIG. 7, for example. The system shown in FIG. 6 uses the force of the difference between the water level of the wash water 5 in the water tank 3 and the head of the discharge nozzle 2 of the toilet bowl 1 to circulate the wash water 5 into the toilet bowl 1 to wash and discharge filth. That is, by operating the cleaning lever 4 between the discharge nozzle 2 in the toilet bowl 1 and the inside of the water tank 3, the flushing valve 4a is opened and the flushing water 5 is discharged from the discharge nozzle 2. The cleaning valve 4a opens only when the user operates the cleaning lever 4, and closes at other times. Here 6 is a ball tap, 7 is an over 70-tube,
8 is a chain, and 9 is a flap valve. In addition, in the case shown in FIG. 7, when the diaphragm 1 of the diaphragm pump 10 for discharging cleaning water is pushed by an external force, the cleaning water 5 in the diaphragm pump 10 is pressurized, and a constant amount of cleaning water 5 is discharged from the discharge nozzle 2. Exhale. Water is supplied to the diaphragm pump 10 in such a manner that the diaphragm 1 moves backward due to the return force of the spring, and a constant amount of water is supplied from the water tank 3. The diaphragm pump 10 is operated by manually (stepping down) the pedal 13, and the diaphragm 1 is pushed by the pump connecting plate 14 connected to the pedal 13, and the cleaning water 5
is discharged, and when the operation of the pedal 13 is released, water is supplied to the diaphragm pump 10 and the pedal 13 returns to its original position.

[Invention tries to solve! 1] 1] 1 In the above-mentioned conventional model, the washing water pressure is weak because the washing water is discharged only by the force of the head difference between the washing water in the water tank 3 and the discharge nozzle 2.

In order to provide sufficient waste cleaning and discharge capacity, the amount of washing water must be increased, the capacity of the tank for pumping becomes large, the installation space must be large, and the number of pumping operations has to be increased. Sometimes it didn't happen.

Further, since the washing water comes out while the user operates the washing lever 4, the amount of washing water is not fixed, and it is difficult to set the capacity of the tank for collecting water.

In addition, the latter of the above conventional examples has features such as high washing water pressure and a small amount of washing water, so that the amount of water remains constant, but it requires the user to operate the pedal 13 with a certain force or more. Therefore, there is a problem in that the cleaning power becomes weak when used by elderly people or young children who have weak operating power.

The present invention has been made in view of the point R, and the purpose of the present invention is to take advantage of the above-mentioned manual pressure washing method, which has the characteristics of high washing water pressure and a small amount of washing water, while improving the conventional method. To provide a flushing water discharging mechanism for a simple flush toilet that can easily discharge flushing water without operating a pedal.

[Means for Solving the Problems] In order to achieve the above object, the flushing water discharge mechanism in the simple flush toilet of the present invention includes a pressurizing tank 16 that stores pressurized air supplied from an air pump 15 for pressurizing the tank, and a diaphragm pump 10. A pressurized tank 16 for cleaning is provided between the pressurized tank 16 and the diaphragm pump 10.
A switching valve 17 is provided to control the pressurized air to be sent from the diaphragm pump 10 to the diaphragm pump 10.

[Action 1: By switching the changeover valve 17 with the operation switch unit 18, pressurized air is sent from the pressurized tank 16 to the diamond 7 ram pump 10 to drive the diaphragm 1], and the cleaning water 5 sucked into the diaphragm pump 10 is sent out. , the toilet bowl 1 can be flushed by discharging cleansing water 5 from the discharge nozzle 2 of the bowl 1.

[Example] As shown in Fig. 1, the toilet bowl A has a toilet bowl 1, and the toilet bowl 1 has a toilet seat 19a which can be rotated up and down, so that the toilet bowl 1 can freely hold ¥1]9b of toilet bowl 1]Mm. A discharge port 20 is provided at the bottom of the toilet bowl 1, and a discharge ff121 is connected below the discharge port 20 so as to communicate with the discharge port 20. 41? There is a discharge port 20 inside the barrel 21.

This motor 22 with a reduction gear is operated by an operation switch unit 18 operated by a remote control via a remote control #124, and the seven-lap valve 9 can be opened and closed by remote control operation. f2! There is a water tank 3 at the upper part of the rear of vessel A.
The water tank 3 has a hand washing section 25 and a ball tap 6. An overflow pipe 7 is introduced into the water tank 3 from the bottom of the water tank 3, and a diaphragm pump is installed at the bottom of the toilet bowl A to discharge overflowing flush water 5 from the water tank 3. 10 is arranged, and the water chamber 2G of the diamond 7 ram pump 10 and the inside of the water tank 3 are communicated through a wash water supply pipe 27.

Cleaning water supply #f! Inside the water tank 3, there is a siphon-shaped suction part 28. A discharge nozzle 2 is provided in the upper part of the toilet bowl 1, and the water chamber 26 of the diamond 7 ram pump 10 and the discharge nozzle 2 are connected by a flush water discharge pipe 29. As shown in FIG.
and an air chamber 30. A center plate 31 is attached to the center of the diaphragm 1, an id pongee 32 is attached to the center plate 31, and a spring 12 is interposed between the id pongee 32 and the id tube 33. be.

This spring 12 urges the diaphragm 1 toward the air chamber 30. A check valve 34 is provided at the connecting portion of the Dia 7 Ram Bump 10 with the flush water supply pipe 27 and the flush water discharge pipe 29. A tank is installed at the bottom of the toilet bowl A adjacent to the Dia 7 Ram Bump 10. An air pump 15 for pressurization and a pressurization tank 16 for storing pressurized air are arranged. Air sent from the air pump 15 is stored in a pressurized tank 16 via a check valve 35.

The pressurized tank 16 is equipped with a pressure switch 36, which detects when the pressure inside the pressurized tank 16 falls below a certain pressure and activates the air pump 15.

That is, the air pump 15 is operated when blowing air to the diamond 7 ram pump 10 during cleaning and when the pressure in the pressurized tank 16 decreases due to long-term retention. The pressurized tank 16 and the air chamber 30 of the diamond 7 ram pump 10 are communicated through an air supply pipe 37, and a switching valve 17 is disposed in the air supply pipe 37. This switching valve 17 is a three-way valve, and can be closed by switching, or can be made to communicate between the pressurized tank 16 and the Diamond 7 Ram Bomb 10, or between the Diamond 7 Ram Bomb 10 and the exhaust pipe 38. ing.

Next, the operation of flushing the toilet bowl 1 after using the toilet will be explained.

Since air is not normally supplied to the air chamber 30 in the diamond 7 ram bomb 10, the air chamber 30 is bent by the spring 12 of the diaphragm 1, and water is sucked in from the cleaning water supply pipe 27 to clean the ice chamber 26. It is filled with water 5. now,
When the cleaning copper 18a is operated with the operation switch section 18, the pressurized tank 16 and the diamond 7 ram pump 10 are communicated with each other through the switching valve 17, and air is supplied from the pressurized tank 16 to the air chamber 30 of the diaphragm pump 10 at a constant pressure. The diaphragm 1 of the Diamond 7 Ram Bump 10 is pushed by air, and the cleaning water 5 in the water chamber 26 of the Diamond 7 Ram Bump 10 is sent out. It is discharged and the inside of the toilet bowl 1 is cleaned. At this time, the motor 22 is also driven by operating the operating copper 17a, the flap valve 9 is opened, and the cleaning water 5 is discharged together with the dirt. When cleaning is finished and the cleaning water 5 is discharged, the switching valve 17 is switched, the air chamber 30 of the diamond 7 ram bomb 10 and the exhaust pipe 38 are communicated, the air in the air chamber 30 is removed, and the diaphragm 1 is opened by the spring 12. Return to Diamond.

Water is sucked into the water chamber 26 of the 7-ram bomb 10 in preparation for the next cleaning. At this time, the motor 22 is driven in the opposite direction to the above, and the flap valve 9 is closed. Further, when the water reservoir operation button 18b of the operation switch section 18 is operated, only the flushing water 5 is discharged without opening the flap valve 9, and the flushing water 5 is stored at the bottom of the toilet bowl 1.

Further, FIG. 4 shows another embodiment. The above embodiment is a Western-style simple flush toilet, but the one shown in FIG. 4 is a Japanese-style simple flush toilet.

In this case, the structure is basically the same as that of the above embodiment except that the shape of the toilet bowl 1 is different, and the shapes and positions of the water tank 3, diamond pump 10, and pressure tank 16 are different.

Furthermore, FIG. 5 shows another embodiment.
It has the same structure as shown in the figure, but the operation switch section 18
A washable indicator lamp 42 is provided. This washable indicator lamp 42 is provided so that the user can check whether air at a predetermined pressure has accumulated in the pressurized tank 16, and turns off when the air pump 15 is operating. The lamp lights up when the toilet bowl 1 is stopped, so the user can check whether the air pressure sent to the diaphragm pump 10 is sufficient when cleaning. There will be no situation where the quality is insufficient.

[Effects of the Invention] As described above, the present invention communicates a pressurized tank that stores pressurized air supplied from an air pump for pressurizing the tank with a diaphragm pump, and also provides pressure during cleaning between the pressurized tank and the diaphragm pump. It is equipped with a switching valve that controls the flow of pressurized air from the tank to the diaphragm pump, so by operating the operation switch and sending air from the pressurized tank to the diaphragm pump, cleaning water can be discharged for cleaning. The toilet bowl can be flushed with a simple switch operation, without the need for pedal operations that require constant force as in conventional toilet bowls. The air pump is not driven only when discharging cleaning water, but also operates other than when cleaning to hold pressurized air in the pressurized tank, which reduces the capacity of the air pump, making the air pump more compact. Therefore, it can be made at low cost and with little noise. Furthermore, since the pressurized discharge of washing water is carried out by the force of air, it can be made into a highly reliable system with low operating noise.
