Abstract

The variable, double, straight-line piping type of water-saving toilet of the present invention comprises: a main toilet body (10) having a bowl (11), a cistern (12), a water-supply pathway (13) connected to the rear of the bowl (11) from the cistern (12), and a cover part (14) which covers the lower part of the cistern (12) and the rear of the bowl (11) and is adapted to guide foul water discharged from the bowl (11) to a floor pipe (15); a variable, double, straight-line pipe (20) incorporating an inner pipe (21) of which one end is connected via a flexible tube (25) to the discharge port (13a) of the bowl (11), an outer pipe (22) which receives part of the inner pipe (21) on the inside thereof and which is equipped with spring-securing parts (22a) on the outside surface on two sides, and a connecting part (23) which forms a receiving space (23a) where cleaning water is received between the inner pipe (21) and the outer pipe (22), the pipe (20) being adapted so as to discharge the foul water and the cleaning water in the bowl (11) by rotating downward under its own weight due to the inflow of cleaning water into the receiving space (23a) because of the increase in cleaning water flowing into the bowl (11) during foul-water discharge; two brackets (30) which are secured either vertically or horizontally on both sides of the rear wall (11b) of the bowl (11), and are equipped with spring-fastening parts (31); and tension springs (40) which exhibit a resilient restoring force such that the variable, double, straight-line pipe (20) rotates upwards after foul-water discharge.

Abstract

The present invention relates to a variable straight pipe-type water-saving toilet, including: a main toilet body (10) including a bowl (11), a water tank (12), a water supply passage (13) connected from the water tank (12) to a rear portion of the bowl (11), and a cover part (14) covering a lower portion of the water tank (12) and the rear portion of the bowl (11) to guide sewage discharged out of the bowl (11) to a bottom pipe (15); a water bag (20) for a water supply partially branching from the water supply passage (13); a bracket (30) including an accommodating portion (31) in which a lower portion of the water bag (20) is accommodated, a lower hanging frame (32) disposed in the water bag (20), and an extension part (33) extending toward a lower portion of the accommodating portion (31); an extension spring (40) accommodated in the water bag (20) and fixed to an upper hanging frame (13b) and the lower hanging frame (32) to generate elastic restoring force for contracting the water bag (20); a guide part (70) hingedly coupled to the extension part (33) of the bracket (30) to guide the elevation of the bracket (30) in the cover part (14); and a variable straight pipe (50) which is connected to an outlet (13a) of the bowl (11) via a corrugated pipe (60), and which is hingedly coupled to the guide part (70) and which discharges the sewage in the bowl (11) through a shrinking movement of the water bag (20).
