ABSTRACT:

TECHNICAL FIELD
The present invention relates to a water-saving toilet characterized by a flexible plumbing tube, which resulted in significant saving of flushing water.
BACKGROUND ART
Due to the shortage of water resource, the problem of wasting water has become a serious public concern. Especially, water used in toilet flushing is a huge waste of resources since the clean water produced by extensive purification steps goes right into sewers in this process.
FIG. 1
is a schematic diagram of a conventional toilet fixture. Referring to
FIG. 1
, a toilet comprises a toilet main body
10
having a water inlet orifice
11
on the top and a water outlet orifice
12
at the bottom, a toilet bowl
13
from which water and waste materials are discharged and is connected to the inlet orifice
11
and the outlet orifice
12
, the first discharge tube
14
the bottom of which makes a direct contact with the outlet orifice
12
and the top of which is positioned higher than the outlet orifice
12
, and the second discharge tube
15
which follows the first tube and guides the waste materials downward to drainage; a water reservoir tank
20
which has an inlet orifice
11
connected to an outlet orifice
22
of the toilet main body
10
; a trip lever
40
which presents at the outside of the water reservoir tank
20
and can move up and down; a packing
31
which controls the opening and closing of the tank outlet orifice
22
by connecting to the lever
40
; and a trap
50
disposed at the first discharge tube
14
of the toilet main body
10
.
When the outlet orifice
22
in the reservoir tank
20
is opened up by pulling down the trip lever
40
, water from the reservoir tank
20
rapidly flows into the toilet main body
10
. The elevated water level in the toilet main body
10
forces the water to exit through the trap
50
by the siphon effect.
The conventional toilets based on the aforementioned water-pressure dependent siphon mechanism consume about 7~13 L of water in an operation and in addition create a noisy flushing sound due to the presence of a trap.
DISCLOSURE OF THE INVENTION
Therefore, the objective of the present invention is to provide a water-saving toilet which does not employ a siphon principle and a trap, thus saving the amount of flushing water.
To achieve the objective, the water-saving toilet of the present invention comprises a toilet main body having an inlet orifice for introducing water through an external water supply tube, a toilet bowl that collects waste materials and receives the flushing water from the inlet orifice, and an outlet orifice for discharging the waste materials and water in the toilet bowl; a discharge tube one end of which is connected to the outlet orifice of the toilet main body and the other end of which is connected to an outside outlet to serve as a discharge passage of the waste materials and water, including a vertically movable curved portion; and means for moving the curved portion of the discharge tube up and down.
Preferably, the discharge tube is made of a flexible material.
