Definitions

  • the present invention relates to a sewage discharge device for a variable type water-saving flush toilet, and more particularly, to a sewage discharge device for a variable type water-saving flush toilet in which a part of flushing water flowing through a flushing water inflow passage is branched so that when flushing water stored in an auxiliary tank disposed at the outer circumference of a sewage discharge tube of the flush toilet reaches a preset amount, sewage contained in a bowl is discharged to the outside by the auxiliary tank's own weight.
  • a flush toilet employs the principle of a siphon in which a certain amount water is contained in a toilet bowl to smoothly remove foul odor or excretions rising from a waste outlet port and cleanly wash the inside of the bowl.
  • This siphon principle refers to a principle in which when a water level in an inverted U-shaped tube forms an equilibrium state with that in the toilet bowl, water is in a stagnant state whereas when the water level in the toilet bowl rises suddenly, water contained in the bowl is discharged to the outside due to a difference in the pressure between the toilet bowl and the siphon tube in a relatively low pressure state while being accompanied by an increase in pressure inside the toilet bowl.
  • a typical flush toilet includes a bowl 2 configured to contain a predetermined amount of water, and a waste wash water tank 1 disposed at a higher position than that of the bowl 2 and configured to store a predetermined amount of waste wash water, the waste wash water tank being connected to the bowl 2 through a water supply passage 2a closed by a packing valve 5, so that the packing valve 5 operated in cooperation with a flush lever installed at the waste wash water tank 1 opens a water feed port 10 by the manipulation of the flush lever 3 to allow water stored in the waste wash water tank 1 to be rapidly supplied to the bowl 2 through the water supply passage 2a.
  • waste including feces and urine precipitated in the bowl is discharged to the outside through a water drainage passage 2b via a drain trap 2c by the siphon effect in which water to be drained along the water drainage passage 2b of the bowl is created by a hydraulic pressure generated in the bowl 2 with increased water level in the bowl 2.
  • the existing flush toilet should conform to a regulation prescribing that the diameter of a sewage discharge tube shall be set to be more than 45 mm, i.e., generally about 45-55 mm, which was determined according to KS standards to smoothly discharge sewage from the bowl, a so called siphon phenomenon is caused to occur in order to wash sewage inside the bowl by a suction force.
  • a so called siphon phenomenon is caused to occur in order to wash sewage inside the bowl by a suction force.
  • water of more than 60 ml should be supplied to the inside of the bowl at least at one time.
  • a water tank is installed and a certain amount of water is stored therein at normal times, and then water is supplied to the inside of the bowl through the water supply passage fluidically communicating with the water tank and the bowl by the opening of an opening/closing stopper attached to an aperture of a water discharge tube having a diameter of about 65 mm or less, which was installed at the inside of the water tank so that the siphon phenomenon occurs to perform the washing operation.
  • the conventional flush toilet also entails a problem in that although flushing water is supplied to the inside of the bowl from a water pipe having an aperture of about 15 mm, the diameter of the sewage discharge tube of the bowl is typically not more than 45-55 mm, and thus the siphon phenomenon cannot occur and the flushing water is discharged to the outside through the sewage discharge tube as it is, which makes it impossible to wash sewage contained in the bowl.
  • the existing flush toilet (partially, a flush value type toilet product with a water feed tube having an aperture of 1 inch is excluded) should necessarily have a water tank function to enable washing of the bowl. For this reason, there is also a spatial restriction because the size of the flush toilet cannot be reduced due to a design limitation and the water tank.
  • a water tank and a toilet stand are integrally manufactured of earthenware into a so-called "one-piece type flush toilet), a defective rate increases and thus a production yield decreases, resulting in a rise of the cost of earthenware products.
  • Korean Patent No. 10-1131810 discloses a water-saving flush toilet having a variable double straight tube, in which the variable double straight tube is configured to be operated in an existing water flow path and a bowl rim manner.
  • the variable double straight tube is downwardly moved so that sewage can be discharged, but a hydraulic pressure of the flushing water drops drastically in a water supply passage fluidically communicating with a water tank and the bowl and a water supply passage formed in the bowl rim, which ultimately makes it impossible to use the flushing water from a tap, and thus there is caused a problem associated with the washing of sewage contained in the bowl.
  • it is difficult to control the delay of the sewage discharge time when the variable double straight tube is downwardly moved during the discharge of sewage occasionally resulting in backflow of some sewage.
  • Korean Patent No. 10-1131810 also discloses that flushing water should be supplied to the bowl until the variable double straight tube is downwardly moved to discharge sewage, and the supplied flushing water is immediately mixed with sewage contained in the bowl and thus is also changed into sewage. Resultantly, waste wash water is squandered, leading to a half-reduction in the water-saving effect.
  • Korean Patent No. 10-1131810 also discloses that the variable double straight tube uses water stored in an auxiliary tank disposed on the outer circumference of a sewage discharge tube as a part of sewage to be discharged, and thus the variable double straight tube is clogged by sewage introduced into the auxiliary tank after a lapse of a predetermined period of time, which causes an erroneous operation of the sewage discharge tube, leading to deterioration of durability of the sewage discharge tube.
  • the present invention has been made to solve the aforementioned problems occurring in the prior art, and it is an object of the present invention to provide a sewage discharge device for a variable type water-saving flush toilet in which a part of flushing water flowing through a flushing water inflow passage is branched and a sewage discharge unit connected to an outlet port of a bowl by a bellows tube is elastically moved downwardly by the branched flushing water's own weight so that the sewage can be sequentially discharged, and the sewage discharge unit can elastically return to its original position after completion of the discharge of the sewage contained in the bowl.
  • Another object of the present invention is to provide a sewage discharge device for a variable type water-saving flush toilet, which can discharge sanitary sewage contained in a bowl of the flush toilet using flushing water directly supplied from a water pipeline even without a water tank.
  • Still another object of the present invention is to provide a sewage discharge device for a variable type water-saving flush toilet, in which a sewage discharge unit can be stably operated if flushing water supplied from a water pipeline is more than a certain pressure despite a change in the pressure of water so that since the sewage discharge device is hardly influenced by the pressure of water supplied, a washing performance can be maintained stably.
  • Yet another object of the present invention is to provide a sewage discharge device for a variable type water-saving flush toilet, in which flushing water supplied from a water pipeline can be used so that the sewage discharge device can contribute to diversification of a toilet bowl design, reductions in the production cost and installation space, and generalization of the use of an automatic flush toilet employing a sensor by eliminating the necessity of a water tank necessary for an existing flush toilet.

  • the present invention has an advantageous effect in that the auxiliary tank is disposed on the outer circumference of the sewage discharge tube to supply a part of flushing water flowing through the flushing water inflow passage to the auxiliary tank through an auxiliary corrugated tube so that sewage can be rapidly discharged to the outside by rotating the sewage discharge tube by the auxiliary tank's own weight.

  • the present invention has an effect in that when the amount of the flushing water supplied to the auxiliary tank is more than a preset level, the operation of the sewage discharge tube can be performed stably, thereby maximally preventing a deterioration in the washing performance according to a change in the pressure of water supplied.
  • a part of flushing water flowing through the flushing water inflow passage is supplied to the auxiliary tank via the flushing water branching unit to allow the age discharge tube to be downwardly operated elastically so that sewage contained in the bowl can be discharged to the outside before flushing water is supplied to the bowl, thereby maximizing the water saving effect.

  • the odor prevention unit 600 includes an odor prevention member 610 that is disposed at the inside of the sewage discharge tube 400, is formed in a hollow shape, and is made of vinyl or thin rubber having flexibility.
  • the odor prevention unit 600 has a hollow shape and is formed of vinyl or rubber having flexibility.
  • one end of the odor prevention member 610 is fixed to one end of an inner circumference of the sewage discharge tube 400.
  • a process of fixing the odor prevention member 610 may be performed by using an adhesive.
  • the other end of the odor prevention member 610 is disposed to form a free end along the other end of the inner circumference of the sewage discharge tube 400. In other words, the other end of the odor prevention member 610 is not fixed at the inside of the sewage discharge tube 400.
  • connection tube 120 when sewage contained in the bowl 110 flows into the corrugated tube 200 through connection tube 120, it can be introduced into a hollow space of the odor prevention member 610 to open the odor prevention member 610.
  • a circumference of the odor prevention member 610 is larger than the outer circumference of the sewage discharge tube 400 so that the odor prevention member 610 can be closely abutted against the outer circumference of the sewage discharge tube 400.
  • the other end of the odor prevention member 610 is maintained in a relatively closed state, and thus it is possible to minimally reduce foul odor generated from a side from which sewage is discharged.
