JPS5930867B2 - Drainage structure in simple flush toilets - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drainage structure for a simple flush toilet that uses a small amount of water to drain and flush feces.

For simple flush toilets, it is assumed that the amount of flushing water used should be kept small, taking into account the capacity of the sewage tank.

With conventional simple flush toilets, both when defecating and urinating, the user presses a foot pedal to discharge the flushing water to drain waste and clean the toilet bowl, which requires a lot of flushing water when defecating. there was.

An object of the present invention is to provide a drainage structure that can reduce the amount of washing water used after defecating by storing a predetermined amount of water in the toilet bowl before defecating. be.

The drainage structure of the simple flush toilet of the present invention is such that a drainage valve 3 is installed in the drainage hole 2 provided between the water storage part of the tank body 1 and the drainage channel 5 at the bottom. A lifting rod 4 is attached to the lower part with its lower end protruding so as to be freely raised and lowered, and a closing tension spring 6 is installed to normally hold the drain valve 3 in a closed state with respect to the drain hole 2. An interlocking mechanism 8 is connected to the movement of the foot pedal 7 that opens and closes the lid 15 for opening and closing the waste discharge hole provided in the toilet main body 12, and a locking ring 9 is fixed to the middle of the elevating rod 4.
The drain valve 3 is opened by engaging a push-up body 11 that moves up and down by operating a hand lever 10 that is tiltably provided on the tank body 1 directly below the tank body 1. .

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 is a partially cutaway side view of a toilet bowl according to the present invention, FIG. 2 is an enlarged front view of the main part, and FIG. 3 is a cross-sectional view taken along the line II in FIG. 2.

In the figure, 1 is the tank body, 2 is a drain hole provided at the bottom of the tank body 1, 3 is a drain valve that allows the drain hole to be closed from the top, 4 is a lifting rod that raises and lowers the drain valve, and 5 is a toilet bowl. Main body 1
A drainage channel communicating with the washing water spout hole provided above the inner wall of No. 2;
Reference numeral 6 indicates a closing spring for keeping the drain valve 3 in close contact with the upper surface of the drain hole 2 at all times, 7 indicates a foot pedal, and 8 closes the filth discharge hole 14 in the toilet main body 12 by depressing the identification pedal 1. an interlocking mechanism for opening the lid 15 and lifting the push-up lever 16 connected to the lower end of the lift lever 4; 9 is a locking ring fixed to the middle of the lift lever 4;
10 is a hand lever provided on the side of the tank body, and 11 is a push-up body that tilts and pushes up the locking ring 9 by operating the pivot 13 of the hand lever 10.

The interlocking mechanism 8 is configured so that the lid body 15 does not open even if the push lever 16 is raised when the lift lever 4 is raised by operating the hand lever 10. It has a link-connected structure connected by .

Next, the operation of this device will be described.

First, in the case of small errands, after pressing the foot pedal I, the lifting rod 4 is activated via the interlocking mechanism 8 and the push-up rod 16.
rises, the drain valve 3 opens, and flushing water is squirted into the toilet main body 12 through the drain channel 5.

At the same time, the lid 15 at the bottom of the toilet main body 12 is also opened to drain the waste water.

When the foot pedal 7 is returned to its original position, the drain valve 3 and the lid body 15 are in a closed state.

Next, in the case of defecating, first use the hand lever 10 before defecating.
If you operate the button, only the drain valve 3 will open, and the lid 15 will be closed, so a predetermined amount of water will be stored in the toilet body 12, and by depressing the foot pedal I after using the toilet, you will be able to open the drain valve 3 in the same way as above. The waste and washing water will be discharged.

As described above, according to the present invention, by operating a hand lever, water can be discharged from the water storage tank and the required amount of water can be stored in the toilet bowl without opening the lid for the filth discharge hole in the toilet bowl body. It can store water only when you need to defecate,
This has the effect that washing water can be saved when cleaning is not necessary.
