Description

    BACKGROUND OF THE INVENTION Field of the Invention
  • The present invention relates to a toilet, and more particularly to a water-saving toilet with a certain base to match with a flushing structure, obtaining a water-saving purpose.
    • Description of the Prior Art
  • Saving water source is an important environmental friendly issue for people. Therefore, a water saving purpose is constantly improved by toilet's manufacturer when using the toilet to urinate and flush the urine.
  • However, such a water-saving toilet still has the following defects:
    1. 1. As flushing urine, three liters of waters are used, but such a flush quantity is greatly more than that of the urinal (i.e., one liter of water).
    2. 2. The water-saving toilet includes a two-section flushing structure, yet such a two-section flushing structure is easy to be broken in a long period of time, causing a replacement trouble.
  • The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
    • SUMMARY OF THE INVENTION
  • The primary object of the present invention is to provide a water-saving toilet that is capable of obtaining a water-saving purpose.
  • Further object of the present invention is to provide a water-saving toilet so that while pressing the flush button, a suitable water flows out of the outflow holes of the first and the second flow pipes in turn to flush the cavity simultaneously, thus obtaining a cleaning purpose.
  • Another object of the present invention is to provide a water-saving toilet that while water flushes into the U-shaped tube, the dirty fluid in the U-shaped tube is flushed outward and only little water is left to achieve water-saving and cleaning purposes.
  • To obtain the above objective, a water-saving toilet provided by the present invention contains:
    • a base including a cavity formed therein, an outlet disposed on a bottom end of the cavity, a U-shaped tube communicating with the outlet, a cushion fixed on an upper portion of the base, a stopping member secured on an upper end of a back side of the base, and a flush button arranged on the stopping member;
    • the stopping member including an inlet pipe disposed on an upper end of an inner space thereof to connect with a first flow pipe and a second flow pipe, both of which are fixed in the upper portion of the base, the first and the second flow pipes respectively including a plurality of outflow holes to flow water outward;
    wherein lengths of the first and the second flow pipes are equal to flow the water at the same speed, wherein when flushing the water, the water flows from the stopping member to the cavity via a first predetermined section of the first flow pipe without the outflow holes, and via a second predetermined section of the second flow pipe of the same length than a third predetermined section of the first flow pipe provided with the outflow holes, said second predetermined section of the second flow pipe being not provided with the outflow holes so that the water flowing toward a distal end of the first flow pipe further flows into the stopping member via the outflow holes of the first flow pipe.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
  • Referring to Figs. 1 and 2, a water-saving toilet 10 in accordance with a preferred embodiment of the present invention comprises a base 11 including a cavity 14 formed therein, an outlet 17 disposed on a bottom end of the cavity 14, a U-shaped tube 18 communicating with the outlet 17, a cushion 13 fixed on an upper portion 12 of the base 11, a stopping member 15 secured on an upper end of a back side of the base 11, and a flush button 16 arranged on the stopping member 15.
  • Referring further to Figs. 2-4, the stopping member 15 includes an inlet pipe 20 disposed on an upper end of an inner space thereof to connect with a first flow pipe 21 and a second flow pipe 22, both of which are fixed in the upper portion 12 of the base 11, the first and the second flow pipes 21, 22 respectively include a plurality of outflow holes 23 to flow water outward, wherein lengths of the first and the second flow pipes 21, 22 are equal to flow the water at the same speed, wherein when flushing the water, the water flows from the stopping member 15 to the cavity 14 via a first predetermined section of the first flow pipe 21 without the outflow holes 23, and via a second predetermined section of the second flow pipe 22 of the same length than a third predetermined section of the first flow pipe 21 provided with the outflow holes 23, said second predetermined section of the second flow pipe 22 being not provided with the outflow holes 23 so that the water flowing toward a distal end of the first flow pipe 21 further flows into the stopping member 15 via the outflow holes 23 of the first flow pipe 21, such that while the flush button 16 is pressed, the water flows out of the outflow holes 23 of the first and the second flow pipes 21, 22 to flush the cavity 14, thereafter the water flows into the U-shaped tube 18 to flush dirty fluid outward, wherein a few water is left in the U-shaped tube 18, and a level of the U-shaped tube 18 is lower than that of the outlet 17 to lower a left water quantity, thus replacing the left water level of the U-shaped tube 18 by using less water quantity to obtain water-saving purpose.
  • As shown in Figs. 5 and 6, a size of the stopping member 15 of the water-saving toilet 10 is decreased, and a flush device is replaced by a manual flush valve 50 or a sensing flush valve 51 based on the requirement.
  • As illustrated in Figs. 7 and 8, in operation, the water-saving toilet 10 is cooperated with a general toilet 30 so that a user uses the water-saving toilet 10 and the general toilet 30 selectively based on different requirements, wherein a squat toilet 31 is severed to urinate. Referring to Fig. 9, a water outflow structure of a urinal 32 is equipped with the U-shaped tube 18 to lower a left water quantity in the urinal 32, thereby decreasing flush water to achieve the water-saving purpose.
  • As shown in Fig. 10, a urine toilet 50 according to another preferred embodiment of the present invention is capable of being used by men and women and comprises a wall 51, a cavity 14, a U-shaped tube 18, and a first guiding pipe 52 of a flush system connected with an outlet head 53 of the wall 51, a second guiding pipe 54 coupled with an outflow pipe 55 of a front end of an upper portion 12, wherein a length of the first guiding tube 52 is equal to that of the second guiding pipe 54 so that the water flushes toward the wall 51 and the cavity 14 simultaneously.
  • While we have shown and described various embodiments in accordance with the present invention, it is clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
