Description

Water-saving toilet bowl {TOILET STOOL FOR SAVING WATER}

The present invention relates to a toilet, and more particularly, to a water-saving toilet that has an improved drain trap structure to consume less water.

Generally, about 6 liters to 8 liters of water is consumed each time the toilet is flushed, and the improvement is urgent in a country where water is scarce.

The toilet of the general structure, as shown in Fig. 1, has a drain trap 2 having a bent portion at approximately the middle height of the bowl 1 as deodorizing means. In other words, the water is always stuck in the bowl by the height of the drain trap 2, and the drain trap is blocked by the water trapped in the bowl, thereby preventing the odor from flowing back from the septic tank (not shown). However, the bowl of the toilet is typically a large structure, so there is not a lot of water hanging there, and when you flush down the toilet, you need more water than the amount of water in the bowl. It was consumed. In addition, if the drain trap is high, the excrement does not fall well and often prevents the drain trap, which causes a lot of inconvenience, such as overflow of water in the bowl. The drain trap, which is much higher than the bottom of the bowl, is not only responsible for consuming much water, but also causes the toilet to become clogged and needs to be improved.

On the other hand, Patent Document 2002-0079616 proposes a so-called water-saving toilet that has an improved structure of the drain trap. The proposed water-saving toilet has a drain trap formed at a height lower than the bottom of the bowl. In other words, water does not lump in a wide bowl of muddy water, but instead of water clogging in a narrow drain trap, it blocks odors with a small amount of water, and discharges feces with a relatively small amount of water even when the water is lowered. It is intended to reduce consumption. On the other hand, in such a structure, when the droppings are dropped while the bowl bottom is dry, the droppings (sides) may stick to the bottom of the bowl, and may not be discharged cleanly. The jaws are slightly raised in the trap side openings, causing a small amount of water to clog the bottom of the bowl. However, since the dropping position of the droppings is not constant according to the user's posture, the droppings often stick to the water-free portion, that is, the medullary portion, and in this case, the dropping is not easy to clean, but in order to finish in a clean state Since the water must be kept down, it may result in the consumption of more water.

As mentioned above, drain traps lower than the bowl bottom of toilet bowls are a useful means of drastically reducing water consumption. However, in the prior art, it was not possible to solve the problem that the fecal clinging to the bowl can not maintain the cleanliness, it was unsanitary or rather consumed more water, and did not achieve its effectiveness.

Accordingly, an object of the present invention is to provide a useful water-saving toilet with substantially reduced water consumption by devising a means for cleaning the feces clinging to the bowl while utilizing the above-described improved trap structure of the water-saving toilet. It is.

The present invention to achieve the above object is provided with a bowl for receiving waste, a plurality of water discharged to flow down along the inner surface of the bowl portion in the bowl having a washing channel for transporting water therein; In the toilet bowl is formed of a rim portion is formed with a washing water discharge hole, the drain portion traps the water and excrement to the outside from the bowl portion and then traps a certain amount of water to block odor, wherein the bowl portion Forming a plurality of washing water spraying holes for directly spraying the body of water to the middle height of the inner surface, characterized in that the drain trap is formed to trap the water to a height lower than the spraying height of the body of water by the spraying holes.

In a preferred form, the drain trap has a lower portion of the bowl portion and an inlet leading to the rear, and has a portion that is bent rearward from the inlet and then bent by the top height of the inlet and extends from the bent portion to the septic tank side outlet. Thus, the bent portion can be configured to be blocked by the amount of water that is locked only the inlet of the drain trap on the bottom of the bowl.

Also in a preferred form, the drain trap has a lower portion of the bowl portion and an inlet leading to the rear and an inclined portion from the inlet to the rear downward, and then bent in the opposite direction, and are formed in a shape extending from the curved portion to the septic tank side outlet. The bent portion in the drain trap may be configured to block water from accumulating, more preferably with a slightly raised jaw at its inlet to allow some water to collect at the bottom of the bowl up to its particular height. Can be.

Also in a preferred form, the drain trap has a lower portion of the bowl and an inlet leading forward and a portion bent in an opposite direction after being inclined forward and downward from the inlet to form a shape that extends from the curved portion to the septic tank side outlet. The bent portion in the drain trap may be configured to block water from accumulating, more preferably with a slightly raised jaw at its inlet to allow some water to collect at the bottom of the bowl up to its particular height. Can be.

Also, preferably, the inner surface of each bowl and the inner surface of each drain trap may be coated with a protective layer by nano coating so that the excrement does not adhere well.

As described above, the present invention has a drain trap formed at a position lower than the bottom of the bowl by the above-described prior art, so that the feces adhering to the head of the bowl are washed away. It is provided with a means for spraying the water stream. Accordingly, the present invention is to provide an effect of increasing the effectiveness of the water-saving toilet by the improved drain trap by maintaining a clean toilet while consuming less water.

With reference to the accompanying drawings will be described preferred embodiments of the present invention. For convenience, the same reference numerals are assigned to the same or corresponding parts in the drawings of each embodiment.
