Definitions

  • Patent Number CA2416848 is analyzed which refers to a dual capacity flush valve assembly where the dual-flush flapper valve assembly, set for a normally short flush, is provided for use with a pivoting flapper valve in a flush tank.
  • the assembly comprises a weight, which moves back and forth along a guide relative to the flapper's pivot point.
  • the moveable weight if activated, temporarily reduces the turning movement of the flexible arm of the flapper ensuring a long flush.
  • the assembly further comprises an actuator to trap and release the weight, resulting in either a short flush (when the weight is remote from the pivot) or a long flush (when the weight is close to the pivot).
  • the flipper assembly is engageable through a resistance force, for selectively triggering the actuator, shifting the weight and resulting in a long flush. After a long flush the assembly resets for a short flush, until it is activated once again.
  • Patent Number CN 1284591 is also analyzed which refers to a double flush appropriate for personal hygiene items and double channel water deposit of toilet water.
  • Said invention is based in on the fact that the water coming from a pipe has a great impulse while the water from a water tank has a great flush rate, the water fill valve has a double control to make the pipe water first flush the toilet and then recover the water from the tank.
  • the oscillating regulation and flush valve used as ancillary to economize water results in the precise control of water consumption and has several optional flush functions.
  • This device is especially appropriate to be used from the foregoing for a toilet with double water channel and can be used to replace the available devices of the flush tank.
  • Patent Number CN1584229 refers to a Double-row pressure-type flushing system.
  • the invention is related to a double row flush system of the pressure type.
  • Said system includes pressure cistern, water intake valve, air intake combined valve, double-row water discharge valve and opening valve for controlling the double-row water discharge valve.
  • Said invention also provides their connection relationship and their respective function, and when compared with traditional pressure-type flushing system, said invention can implement double discharge function so as to save more can water.
  • Patent Number DE3319649 refers to an economic dual flush-volume outflow valve to reduce the domestic-water requirement in WC flushing operations, an outlet valve is designed as a dual valve having two outlet planes, for emptying a partial quantity or the entire quantity of water stored, as desired.
  • Patent Number DE4236464 refers to a Leak-free double valve with separate cleaning facility.
  • the two valves (12,13) operate in series and have a trapped space (8) which is vented via a vent hole (9) and a bore (10) through an extension of the valve rod (15) for the lower valve.
  • a sleeve (16) sliding telescopically on the valve rod operates the upper valve.
  • the operating cylinder has a main piston and three control pistons to operate the two valves together or separately. For separate operation each valve is lifted independently while the other is held closed by a combination of spring pressure and hydraulic pressure. The valve travel is limited by stops inside the control cylinder.
  • a main spring (21) provides the main closing force for the valves, with a second spring (24) to control the relative pressure between the two valves.
  • Paten Number GB 2300006 refers to a dual flush device for a valve-flush toilet cistern.
  • Said toilet flushing mechanism includes a dual flush device for effecting both a short flush cycle and a long flush cycle in a toilet tank including a flush valve actuated by an actuation arm.
  • a cam operable by a handle has a rotatably supported stand adjacent to the actuation arm. When rotated in a first direction, the cam acts to press against and pivot the actuation arm to effect the short flush.
  • a lever is pivotably supported with respect to the actuation arm and pivots between a first position out of blocking contact with the actuation arm and a second position where the lever blocks return of the actuation arm for a predetermined period of time when the cam is rotated in the second direction.
  • a float is coupled to the lever for determining the predetermined period of time.
  • Patent Number JP8302782 refers to a toilet drainage system having water economizing function.
  • PROBLEM TO BE SOLVED To obtain improved double drainage systems, in which water is saved, by selecting long flushing or short flushing by selecting the rotation of one handle by a user and selectively driving one drainage valve. SOLUTION: A handle 32 is rotated in the counterclockwise direction in a front view in the case of long flushing. The pawl nose section 43 of a cam 42 is brought into contact with the upper section of the second arm 36 of a driving lever 34 by the rotation. Consequently, the first arm 35 is lifted, and a flapper 64 is lifted from a valve seat 62.
  • the movement of the arm 35 is controlled by a cutoff wall 90.
  • the handle 32 is rotated in the clockwise direction in the case of short flushing.
  • the pawl nose section 44 of the cam 42 is brought into contact with the lower section of the arm 36 by the rotation.
  • the arm 35 is lifted less than in the case of long flushing. Since the pawl nose section 43 is brought into contact with the upper section of the cutoff wall 90 and the revolution excess of the lever 34 is prevented at that time, the flapper 64 is not elevated from the valve seat 62 up to height in the case of long flushing.

  • Each valve has a cone (12, 22) and a valve seat (11, 21), and are shaped and sized to allow the lower valve (10) to nest fully in the upper valve (20).
  • the double valve assembly is controlled by a guide rod (15) attached to the valve (10) and slidable in the tubular rod (25) fixed to valve (22), and operated by knob (31).

  • the bidet should be inserted in a toilette bowl in such way to lay with its wide edge (3 - 4 cm) over the edge of a toilette bowl. It is made of flexible plastic, and its volume is adapted to a toilette bowl.
  • the water should be poured in a bidet from the sink or bath tub next to the toilet bowl before it is inserted in the toilet bowl, or, if the empty bidet has already been inserted, from another holder, or by a special pipe, connected to the double valve next to the toilet cistern.
