Toilet bowl with changeable water seal
The present invention relates to a toilet bowl with a changeable water seal, which comprises an upper region, a waste drain outlet of the upper region, a lower region and a waste drain outlet of the lower region. A deviated waste discharge passage is fixed on a supporting shaft or a supporting bore. A reposition apparatus is arranged for the reposition of the waste discharged passage, the lower end of which surrounds the waste drain outlet of the upper region, the higher end of which could be depressed and repositioned automatically and be lead to the waste drain outlet of the lower region. This invention could overcome these disadvantages that immobile waste discharge passage of the traditional toilet bowl between the waste drain outlet of the upper region and the waste drain outlet of the lower region has a higher water seal, a higher water resistance and higher water consume. The waste discharge passage of this invention is deviated automatically to form a lower water seal while flushing, and is repositioned automatically to form a higher water seal while non-flushing. It can not only seal the dour but also improve the flushing efficiency and save water. The structure of invention is simple and reliable and has lower cost.
The present invention generally relates to a toilet bowl, and more specifically, to a variable water sealed toilet bowl.
BACKGROUND OF THE INVENTIONThe water seal device of the traditional toilet bowl is a fixed bending sewage draining passage with deeper water storage, including an upper chamber, a lower chamber, an upper chamber outlet and a lower chamber outlet. Although the waterseal in the bending passage of the lower chamber seals the smell, a resulted high water resistance decreases the flush effect significantly and results in wasting water badly; meanwhile, the larger curvature of the sewage draining passage leads to an increased waster resistance, thereby the sewage tends to stagnate in it, or worse, jamming the passage and rendering the toilet bowl out of work.
SUMMARY OF THE INVENTIONAiming at solving the deficiency of the prior art, the present invention provides a variable water sealed toilet bowl, which is equipped with a tiltable sewage draining passage enabling the change in the height of the waterseal: at other times the waterseal is high that providing a more desirable blocking effect, when it is flushing, the height of waterseal can be lowered and has the effect of reducing the flush resistance and saving the water for flush.
The object of the present invention is achieved by the following schemes:
A variable water sealed toilet bowl, comprising an upper chamber, a lower chamber, an upper chamber outlet, and a lower chamber outlet, wherein it's equipped with a tiltable sewage draining passage; the tiltable sewage draining passage is mounted on a supporting axle or supporting hole, its lower end surrounding the upper chamber outlet and its higher end that can lower and reset automatically leading to the lower chamber outlet, and the reset device of tiltable sewage draining passage is also equipped.
The tiltable sewage draining passage mentioned above may be rotated around the supporting axle, the upper limit of the rotation is the higher position of the tiltable sewage draining passage; and the lower limit of the rotation is the lower position of the tiltable sewage draining passage. At other times, the tiltable sewage draining passage is kept at the higher position by the reset device, thus the waterseal is high; when it is flushing, owing to the current, the tiltable sewage draining passage overcomes the force from the reset device to rotate around the supporting axle or supporting hole and move into the lower position, which lowers the height of the waterseal and achieves the effect of lowering the flush resistance and saving water for flush. After flush, the tiltable sewage draining passage is reset by the reset device and resume its position with a high waterseal.
The described tiltable sewage draining passage can be a U-pipe sewage draining passage, a ┐-pipe sewage draining passage or tiltable tubular sewage draining passages of any other shapes.
The described reset device can be selected from the counterweight reset device, the compression spring reset device, the tension spring reset device and the combined reset device of tension spring and compression spring or any other devices that can replace the tiltable sewage draining passage from the lower position to the higher position.
The supporting axle or supporting hole of the described tiltable sewage draining passage is mounted on the outside of the upper chamber outlet or the outside of the lower chamber outlet in the lower chamber.
More specifically, the object of the present invention is further achieved by the following technical measures:
a. The described tiltable sewage draining passage is tubular, namely, tiltable tubular sewage draining passage, and the configuration of the tiltable tubular sewage draining passage is: a flexible tubular sewage draining passage is mounted on the outside groove of the elbowed upper chamber outlet, the tiltable frame tilting around the axle is supported in the supporting hole on the hoop supporter fastened with bolt, and there is a reset device on one side of the tiltable frame, the other side thereof inclines to extend upwards to join the flexible tubular sewage draining passage that is extending with it simultaneously or join the tubular sewage draining passage connected to the flexible tubular sewage draining passage to form a horizontal, vertical or inclined tiltable outlet leading to the lower chamber outlet, and is tilted and reset with the tiltable frame synchronously; there is a narrow plate in the middle of the frame edge on one side of the tiltable frame, that bends downwards to form a bump, the narrow plate bending downwards and the bump form the limit plate and limit bump limiting tilt and reset.
b. The described tiltable sewage draining passage is basin-shaped, namely, the variable waterseal is basin-shaped variable waterseal, which comprise: a basin-shaped sewage draining passage with a axle and capable of tilt around the axle, that is supported in the supporting hole on the hoop supporter fastened with bolt on the outside of the upper chamber outlet, and the upper chamber outlet extends into the lower end of the basin-shaped sewage draining passage, and the basin-shaped sewage draining passage inclines right upwards and extends to the horizontal tilting outlet, and there exists reset counterweight on the left outside of the basin-shaped sewage draining passage; the horizontal plate on the top of the supporter is the limit plate, a bending bump is the limit bump; the bottom of the supporter is fastened by screws.
The advantage of the present invention is in eliminating the high waterseal, high waster resistance and heavy waste of water of the fixed sewage draining passage between the upper chamber outlet and the lower chamber outlet in traditional toilet bowl. Design the sewage draining passage as the variable tiltable sewage draining passage that can tilt automatically into low waterseal when it is flushing and reset automatically into high waterseal when it doesn't flush seals the smell and improves the flush effect greatly, and the water is saved, thus, its structure is simple and reliable, the price performance ratio is high.
