Description

[Detailed description of the invention] This invention is a siphon-type and siphon-jet type flush toilet that quickly suctions and discharges waste by filling the drainage channel of the toilet bowl with flushing water and causing a siphon effect. (hereinafter simply referred to as a toilet bowl), and its purpose is to cause a siphon effect using the minimum amount of flushing water, thereby achieving a large water-saving effect.

Conventionally, this type of toilet bowl discharges a considerable amount of water and requires a large amount of water to fill the drain channel.

Therefore, as a method to save water, methods are used to bend the drainage channel behind the trap part or narrow a part of the drainage channel, but due to the problem of clogging with waste,
These methods also have limitations and have not been very effective.

This invention was devised in view of the above problems,
By forming a valve part in the drainage channel of the toilet bowl, the purpose of which is to quickly fill the drainage channel with water, it prevents water from flowing out before the drain channel is filled with water, thereby preventing a siphon effect. The purpose is to save water quickly, and the embodiment will be described below with reference to the drawings. Reference numeral 1 denotes a toilet bowl, a trap part 2, and a drainage channel part 3 formed from the trap part 2 to a drain port 10.
, a bowl part 4, and a rim water passage part 5, and the drainage channel part 3 located behind the lower end 6' of the hanging part 6 provided to form the trap part 2 is made of elastic material such as rubber or soft vinyl chloride resin. A siphon promoting valve having a plurality of tongue-shaped pieces made of material in the horizontal direction at the center is attached to the four inner wall parts 7 of the drainage channel part 3.
It fits inside.

As shown in FIGS. 2 and 5, the siphon promoting valve 9 has a tongue-shaped piece 8 integrally formed on the inner wall of a watertight backing 12 and a discharge pipe 11 having an inner diameter into which a drain port 10 is inserted. May be used together.

To explain the operation, as shown in Fig. 3, the cleaning water from the tank (not shown) outside the toilet bowl 1 is
'Jj is guided to the water passage section 5, flows on the surface of the pot section 4, and reaches the trap section 2.

Thereafter, as shown by the arrow in FIG.
t, the water reaches the siphon promoting valve 9, and due to the tongue 8 of the siphon promoting valve 9 and the water flowing toward the center due to the tongue 8, the drainage channel becomes nearly blocked, and the inside of the drainage channel 3 is immediately drained. The siphon action starts in the drainage channel when it is filled with water.

Further, at the start of this siphon action, the water level in the trap part 2 on the pot part 4 side rises from the initial water level (flowing water surface A), and the resulting pressure accelerates the siphon action.

Due to this siphon action, the tongue-shaped piece 8 is pushed down toward the discharge pipe 11 as shown in FIG.

Therefore, only a small amount of flushing water is discharged until the inside of the drainage channel 3 is filled with water. Conventionally, this type of toilet bowl is filled with flushing water due to the difference between the amount of drainage and the amount of inflow, so a large amount of water and It used to take a long time and about 10 to 15 liters of washing water, but according to the present invention, washing can be done in 5 to 71 liters, and it can be done in a short time using less than half the amount of water compared to conventional methods. Ta.

The means for attaching the siphon accelerator valve 9 is not limited to the disclosed embodiments, and adhesives or the like may also be used.

As explained below, the present invention is half as effective as the conventional one by providing a siphon accelerator valve having a plurality of tongue-like pieces projecting toward the center at a suitable location below the water surface in the drain channel of the toilet bowl. This is an extremely water-saving device that can be used for cleaning with the following amount of cleaning water.
