- The present invention will be understood from the following detailed description of preferred embodiments, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail.
-
FIG. 1 schematically illustrates a flush toilet, according to one embodiment of the invention. - The flush toilet is marked herein by
reference numeral 10.Reference numeral 14 denotes the bowl of the flush toilet, andreference numeral 12 denotes the flush tank thereof. -
Reference numeral 18 denotes a domestic water source, from which water is supplied toflush tank 12 viapipe 20. - The additional visible parts, which characterize embodiments of the present invention, are
secondary flush tank 16, which is provided with water supply fromdomestic water source 18, viapipe 22. Afoot pedal 24 is used to trigger flushing of water fromsecondary flush tank 16, as will be further detailed hereinafter. -
FIG. 2 schematically illustrates the flush toilet ofFIG. 1 , while spraying. - According to embodiments of the present invention, the operation of the flush toilet comprises two stages: at the first stage, bend (trap) 56 of the toilet is emptied, and at the second stage,
sprayers 26spray water 54, refilling the trap. The illustration refers to the second stage. Pipe 28 provides the required water fromsecond pump 44 tosprayers 26. - Each of
FIGS. 3 to 5 is a sectional view of a flush toilet, which schematically illustrate a stage in flushing the toilet, according to one embodiment of the invention. -
FIG. 3 schematically illustrates the flush toilet in a situation wherein bend (trap) 56 is filled with water. - At this stage, standing
water 30 intrap 56 is used to sealoutlet 62 ofbowl 14, thereby preventing the release of foul air from the sewer. - At this stage, the user urinates, and then presses foot pedal 24 (not seen in this illustration). As a result,
first pump 38 is activated. First pump 38 pumps (draws) the content of bend (trap) 56, until emptied. The content is pushed by the pump intodrainpipe 42. -
FIG. 4 schematically illustrates the emptied flush toilet. -
FIG. 5 schematically illustrates the flush toilet in a situation whereinsecond pump 44flushes 64 water fromsecondary flush tank 16, intobowl 14, viasprayers 26. - The water quantity used for spraying should be at least the quantity required for refilling
bend 56. This can be adjusted by setting acontrol unit 60 that controls the operation ofsecond pump 44. The control unit may be a circuit, integrated circuit, chip, and so on. It may also comprise a timer. For example, the timer may be used for counting N seconds for activating the first pump to empty the bend, and for M seconds for flushing the toilet. - Thus, the timer is used as an alternative to a sensor for sensing that the toilet bend is emptied, and that the quantity of water flushed into the bowl is adequate to seal the bend.
- The water quantity in
secondary flush tank 16 is retained at a certain level by afaucet 50 connected to a water source, and afloat 48 that controls the tap to get closed when the water in the flush tank passes beyond a certain level. This mechanism is common in retaining the water level in flush tanks. -
FIG. 6 is a block diagram schematically illustrating the components and process flow of a flush toilet, according to one embodiment of the invention. - From the process aspect, the following steps are carried out:
- Step (A): After urinating, the user presses
foot pedal 24.Control unit 60 senses the event of pressingfoot pedal 24, and operates as follows: - Step (B): The content of bend (trap) 56 is pumped by
first pump 38 intodrainpipe 42. - Step (C): The
second pump 44 is activated to flushtoilet bowl 14. The flushed water refills bend (trap) 56. - The point that characterizes the operation of this embodiment of the invention in comparison to the prior art is the quantity of the flushed water in step (C). This quantity is at least the quantity required for sealing bend (trap) 56. This quantity is less than the quantity of water used for “full” flushing or “half” flushing of a common toilet bowl (i.e., flushing after urinating in common flush toilets). The lesser quantity is adequate since the bend (trap) of the toilet bowl is emptied before flushing, and therefore the flushing only washes up the bowl, and seals the bend (trap).
- As such, using the present invention results in less water for flushing a flush toilet in comparison to any flushing mechanism of the prior art.
- An additional advantage of the present invention is the fact that the user does not have to touch the flushing handle, as in a common flush toilet.
- Since
foot pedal 24 is used only as a sensor for indicating that the user has activated the flushing process, the pedal can be replaced by a switch attached to the floor. The mechanism of a switch is much simpler and more reliable than the mechanism of the pedal. - The
secondary flush tank 16 is only an example. Actually, the water of the “main”flush tank 12 may be used as well. -
FIG. 7 is a block diagram schematically illustrating the components and process flow of a simplified flush toilet, according to one embodiment of the invention. - According to this embodiment of the invention, only one pump is used:
first pump 38.Second pump 44 is replaced by asolenoid 58, which is a simpler component. Furthermore, there is no use of a secondary flush tank. - Using this system, the following steps are carried out:
- Step (A): After urinating, the user presses
foot pedal 24.Control unit 60 senses the event of pressingfoot pedal 24, and operates as follows: - Step (B): The content of bend (trap) 56 is pumped by
first pump 38 intodrainpipe 42. - Step (C):
Control unit 60 activatessolenoid 58 that enables/disables water from a domestic water source 18 (illustrated inFIG. 1 ) to flushtoilet bowl 14. The flushed water refills bend (trap) 56. - The absence of a
second pump 44 may reflect the way the flushing is carried out, since water pressure from the water source may not be adequate to generate the necessary spray for flushing the toilet bowl. On the other hand, this way the mechanism is simpler, as neither secondary flush tank or second pump are required. -
Sprayers 26 enable utilizing the flushed water more efficiently, thereby enabling obtaining the same cleaning effect by lesser quantity of water. - According to one embodiment of the invention, the secondary tank comprises an inlet (not illustrated) for inserting therein a disinfectant, odor mask, and so on. Alternatively, the system may comprise means for connecting therein a container of disinfectant, odor mask, and so on.
-
FIG. 8 schematically illustrates a gear pump that can be used aspumps - The pump, which is marked herein by
reference numeral 70, compriseshousing 76 having afluid inlet 72, andfluid outlet 74. Two interlacedgears casing 76. The gaps between the gears and hosing 76 are sealed. An electrical motor rotates the pump. - As the gears rotate, they separate on the intake side of the pump, creating a void and suction that is filled by fluid. The fluid is carried by the gears to the discharge side of the pump, where the meshing of the gears displaces the fluid. The mechanical clearances are “small”. The tight clearances, along with the speed of rotation, effectively prevent the fluid from leaking backwards.
- The ears may be rotated in the opposite direction, thereby allowing opening jams in
pipe 36, which sucks standingfluid 30 fromtrap 56. - The pumps, solenoid, and control unit use electric power for their operation. The electric power may be provided by batteries or by the domestic electric power supply.
