Description

[Detailed description of the invention] The present invention relates to a simple flush toilet, and its gist is that the waste receptacle is provided with an on-off valve 3 at the toilet tank opening 2 of the tank 1, and the inlet 5 of the pressurized pump 4 and the water storage tank. Connect the small-diameter outflow lower with a small outflow amount of 6, attach one end of the pump connecting rod 10 to the pressurizing drive part 11 of the pressurized pump 4, and connect the pump connecting rod 10 and other parts to the foot pedal 12 to open the on-off valve 3. The end portion is slidably inserted and a locking portion 13 is provided at the tip to prevent it from slipping out.
A quick return spring 14 for immediately returning the on-off valve 3 urges the on-off valve 3 in the closing direction, and the pressurizing drive unit 11
The present invention relates to a simple flush toilet in which a pressurizing drive unit 11 is biased in the return direction by a slow return spring 15 for returning the opening/closing valve later than the opening/closing valve 3.

When using a simple flush toilet in areas such as mountain huts where water sources are limited and water conservation is required, people often step on the pedal repeatedly for fun or as a prank, causing water to drain into the tank several times. may also be discharged senselessly.

However, with conventional simple flush toilets, the pedal returns in about 2 seconds and the pressurized pump is set to a state where water can be drained, making it possible to flush water at an appropriate rhythm over and over again. However, it had the disadvantages of wasted water and wear and tear on mechanical parts.

Furthermore, conventional simple flush toilets have the disadvantage that air enters the pressurized pump and is discharged in a state where the air is mixed with the flushing water.

The present invention was developed in view of the shortcomings of the conventional example with an inclined top.The purpose of this invention is to prevent accidental drainage by delaying the return speed of the pressurized pump, thereby reducing wasted water and damage to the mechanical parts. To provide a simple flush toilet capable of preventing wear and tear and preventing air from entering flush water.

The present invention will be explained in detail below with reference to the accompanying drawings.

Reference numeral 3 denotes an on-off valve that is installed at the toilet tank opening 2 of the tank 1 and can be opened and closed vertically. Patsukin 1
7 and closes the toilet tank opening 2, preventing the inside of the toilet tank below the toilet tank opening 2 from being seen and odor from coming up.

Reference numeral 12 denotes a pedal rotatably supported by the main body 19 via a shaft 18, the front end (tread portion 20) of which protrudes outside the main body 19, and the rear end thereof housed within the main body 19.

21 is a U-shaped sink of the pedal 12, and the shaft 22
A reinforcing plate 23 is fixed to the U-shaped sunk 21 with screws 24.

Spring support plate 25 and U-shaped sunk 21 fixed to main body 19
A quick return spring 14 is stretched between the opening and closing valve 3 to bias the opening and closing valve 3 in the closing direction, and the rear end of the pedal 12 and the opening and closing valve 3 are connected by a link mechanism 26.

Thus, when the foot 20 of the foot pedal 12 is depressed, the on-off valve 3 opens, and when the foot 20 is released, the spring force of the quick return spring 14 causes the foot 20 to immediately rise and the on-off valve 3 to close.

4 is a pressure pump such as a diaphragm pump, the inlet 5 of the pressure pump 4 and the outflow lower of the water storage tank 6 are connected by a connecting pipe 27, and the discharge port 28 of the pressure pump 4 and the waste receptacle are connected to the tank 1. The inner upper part is connected by a flexible pipe 29.

Reference numeral 9 denotes a cap that is removably fitted onto the outflow lower of the water storage tank 6. This cap 9 has a small hole 8 that is smaller than the outflow lower, and this small hole 8 makes the outflow lower smaller in diameter. This is to reduce the amount of outflow.

30 is a water faucet equipped with a ball tap valve 31, and the water level in the water storage tank 6 is adjusted to W by the action of this ball tap valve 31.
It is maintained at a height of L.

Reference numeral 11 denotes a pressurizing drive part of the pressurizing pump 4. When the pressurizing driving part 11 is pushed downward, the water in the water storage tank 6 is sent to the tank 1 by the pressurizing pump 4, and the waste receiver is The inside of tank 1 is cleaned.

Reference numeral 10 designates a pump connecting rod, and a U-shaped sink 32 at one end of the pump connecting rod 10 is attached to the pressurizing drive section 11 via a lever 34 pivotally supported on the main body 19 by a pin 33. The other end is a U-shaped sink 21 and a reinforcing plate 23
It is slidably inserted into a through hole 35 provided through the hole 35, and a locking portion 13 larger than the through hole 35 is provided at the tip thereof.

The locking portion 13 may be a nut 36 screwed onto the pump connecting rod 10.

Reference numeral 15 denotes a slow return spring, which urges the pressurizing drive unit 11 in the upward direction, and is stretched between the pump connecting rod 10 or the lever 34 and the main body 19, etc.

The slow return spring 15 refers to the pressurizing drive unit 1 pushed downward.
1 rises due to the spring force, and the pressurized pump 4 is able to drain water at a return speed until the depressed pedal 12 and the opened on-off valve 3 return to their original positions due to the quick return spring 14. (The slow return spring 1-A15 is not necessarily weaker than the quick return spring 14.)

). When the foot pedal 12 is stepped on, the on-off valve 3 is opened via the link mechanism 26, and the locking part 13 is pulled by the U-shaped socket 21 and pushes the pressurizing drive part 11, so that the waste receptacle is opened in the tank 1. Water flows out from the upper part and the waste receptacle is used to clean the tank 1.

When the foot pedal 12 is released, the foot pedal 12 is immediately returned to its original position by the spring force of the quick return spring 14, and the on-off valve 3 is closed.

A cap 9 having a small hole 8 is provided on the outflow lower part of the water storage tank 6.
Because of this, the amount of water flowing into the pressure pump 4 from the small hole 8 is small, and the return speed of the pressure pump 4 is slow. Therefore, even if the pedal 12 is released, the pressure drive unit 11 does not move. Immediately after the pedal 12 is released, the pump connecting rod 10 and the U-shape sink 21 slide against each other as shown by the broken line in FIG. gradually rises, and as shown in Figure 3, the locking part 13 stops against the U-shaped sink 21, and the pressurizing pump 4 is set in a state where it can drain water.

Note that by replacing the cap 9 with one having a different diameter of the small hole 8, it is possible to adjust the delay in the return time of the pressurizing pump 4.

As described above, the waste receptacle is equipped with an on-off valve at the toilet tank opening, connects the inlet of the pressurized pump to the small diameter outlet of the water storage tank, and connects one end of the pump connecting rod to the pressurized pump. Attached to the pressurizing drive part of the pump, the other end of the pump connecting rod is slidably inserted into the foot pedal for opening the on-off valve, and a locking part is provided at the tip to prevent the on-off valve from returning immediately. A quick return spring urges the on-off valve in the closing direction, and a delay return spring for returning the pressurizing drive part later than the on-off valve urges the pressurizing drive part in the returning direction. Therefore, the amount of water flowing into the pressurized pump is small because the water flow is restricted to the outlet with a small amount of water flowing out.As a result, the return speed of the pressurized pump is slow. When the pedal is released, even if the pedal returns immediately, the pressurized pump takes time to return, making it impossible to drain water continuously many times, and causing waste of water due to continuous drainage due to mischief etc. This has the advantage of preventing wear and tear on parts.

Furthermore, the slow return speed of the pressurized pump also dampens mischievous intentions, and the effect is even more significant.

Moreover, even though the pressurized pump does not return immediately, the on-off valve is immediately closed by the quick return spring, so no odor will come up from the toilet tank opening.

Furthermore, since the outflow port of the water storage tank is made small, there is an advantage that air does not enter the pressurized pump, and there is no possibility that air will mix with the washing water and deteriorate the washing efficiency.
