Claims
- 1. A flush water supply system for a toilet, comprising:
- (a) a toilet stool having a plurality of supply ports;
- (b) a pipeline means for supplying flush water to said toilet stool, said pipeline means including a plurality of branched pipelines each having an end connected to a respective one of said supply ports of said toilet stool;
- (c) means for differentiating the flows of said branched pipelines from one another, wherein said differentiating means is comprised of a plurality of constant flow valves mounted one in each of said branched pipelines for obtaining a predetermined amount of discharge flow, the constant flow valves including a water passage and means for adjusting the cross-sectional area of the water passage after the water supply pressure reaches a predetermined value;
- (d) a plurality of electrically operable valves mounted one in each of said branched pipelines upstream from said constant flow valve;
- (e) a starting-of-flushing input means for accepting an input for starting the supply of flush water; and
- (f) a control means for driving the electrically operable valves in a preset order in response to the input for starting the supply of flush water, and for keeping said electrically operable valve in an opened position for a preset period of time.
- 2. A flush water supply system according to claim 1, in which said toilet stool includes a bowl, a trap drainage, a rim formed on and along an upper peripheral edge of said bowl and having watershooting holes and a waterway leading to said watershooting holes, and a rim water-supply chamber communicating with said waterway of said rim, said supply ports of said toilet stool including a first supply port disposed at said rim water-supply chamber, and a second supply port disposed at a bottom of said bowl, said branched pipelines including a first branch pipeline connected to said first supply port, and a second branch pipeline connected to said second supply pipeline.
- 3. A flush water supply system according to claim 2, in which said second supply port is a jet nozzle pointing to an inlet of said trap drainage.
- 4. A flush water supply system according to claim 3, in which said control means is operable to open firstly one of the electrically operable valves in said first branch pipeline for a predetermined period of time, and then the other electrically operable valve in said second branch pipeline for a predetermined period of time.
- 5. A flush water supply system according to claim 1, in which said toilet stool includes a bowl, a trap drainage, a rim formed on and along an upper peripheral edge of said bowl and having watershooting holes and a waterway leading to said watershooting holes, and a rim water-supply chamber communicating with said waterway of said rim, said supply ports of said toilet stool including a first supply port disposed at said rim water-supply chamber, and a second supply port disposed at said trap drainage, said branched pipelines including a first branch pipeline and a second branch pipeline respectively connected to said first and second supply ports.
- 6. A flush water supply system according to claim 5, in which said second supply port is a shower mouth piece.
- 7. A flush water supply system according to claim 1, in which said electrically operable valves are self-maintaining latching-type valves.
- 8. A flush water supply system for a toilet, comprising:
- (a) a toilet stool having a plurality of supply ports;
- (b) a pipeline means for supplying flush water to said toilet stool, said pipeline means including a plurality of branched pipelines each having an end connected to a respective one of said supply ports of said toilet stool;
- (c) means for differentiating the flows of said branched pipelines from one another, wherein said differentiating means is comprised of a plurality of constant flow valves mounted one in each of said branched pipelines for obtaining a predetermined amount of discharge flow, the constant flow valves including a water passage and means for adjusting the cross-sectional area of the water passage after the water supply pressure reaches a predetermined value;
- (d) a plurality of electrically operable latching-type valves mounted one in each of said branched pipelines upstream from said constant flow valve;
- (e) a starting-of-flushing input means for accepting an input for starting the supply of flush water; and
- (f) a control means for driving the electrically operable latching-type valves in a preset order in response to the input for starting the supply of flush water, and for keeping said electrically operable latching-type valves in an opened position for a preset period of time.
- 9. A flush water supply system according to claim 8, in which said electrically operable latching-type valves are opened by an electrical pulse.
- 10. A flush water supply system according to claim 9, in which said electrically operable latching-type valve are opened by an amount dependent upon the number of pulses applied to said electrically operable latching-type valve.
