Definitions

• maintenance inlet pipe 241 may be connected to a split portion of a hose or pipe leading to the plumbing fixture, as explained in further detail hereinbelow.
• cleaning and maintenance assembly 204 ensures that liquid flowing out of maintenance-assembly outlet 242 retains the water pressure present in that hose or pipe, as opposed to water flowing into the drain through the plumbing fixture, in which the water pressure is greatly reduced.
• the dimensions of pipe 238, maintenance inlet pipe 241, and, where relevant, pipe 260 may be selected to maintain the fluid pressure within pipe 238 substantially equal to the pressure emanating from the water mains or from the source of the liquid.
• FIG 8 is a schematic illustration of another electronically- operated drain cleaning and maintenance system 800 according to an embodiment of the present invention.
• System 800 is substantially similar to system 200 described hereinabove with respect to Figures 2A and 2B.
• the main change between the two systems is that siphon 220 (of Figures 2A and 2B) has been replaced by a U-shaped drain trap 820 in Figure 8.
• the sewage drain pipe 830 of Figure 8 is bent, as compared to the linear sewage drain pipe 230 of Figures 2A and 2B.
• maintenance-assembly outlet 242 of cleaning and maintenance assembly 204 is connected to second inlet 916 of drain trap 920 by pipe 260.
• cleaning and maintenance assembly 204 may be connected to second inlet 916 directly, substantially as shown in Figure 2B.
• one or more of the nozzle outlets of nozzle 1100 may extend beyond the footprint of the nozzle.
• one or more of the nozzle outlets may comprise an nozzle outlet pipe or conduit.
• end 1210 of pipe 260 disposed within second inlet 316 is open, allowing water, or another liquid, to flow freely through pipe 260 and into siphon 320, at the angle defined by second inlet 316, without any further obstructions. In this arrangement, no nozzle is used.
• a nozzle 1220 is disposed at end 1210 of pipe 260 within second inlet 316.
• Nozzle 1220 includes two nozzle outlets 1222 and 1224, allowing water to flow out of end 1210, and to be redirected to flow into an upstream portion and into a downstream portion of siphon 320, as indicated by arrows.
• Embodiment 11 The drain cleaning and maintenance system of any one of embodiments 1 to 7, wherein when the maintenance-assembly inlet is connected to the source of pressurized liquid and the electronic valve is in the open state, the pressure differential is at most 15%.
• Embodiment 12 The drain cleaning and maintenance system of any one of embodiments 1 to 7, wherein when the maintenance-assembly inlet is connected to the source of pressurized liquid and the electronic valve is in the open state, the pressure differential is at most 10%.
• Embodiment 16 The drain cleaning and maintenance system of any one of embodiments 1 to 13, wherein, when the maintenance-assembly inlet is connected to the source of pressurized liquid and the electronic valve is in the open state, the absolute input pressure is at least 3 bar.
• Embodiment 34 The drain cleaning and maintenance assembly of any one of embodiments 29 to 32, wherein the electronic controller and the power source are disposed on an exterior wall of the drain trap.
• Embodiment 46 A drain device, including: a drain trap, having a first inlet, adapted to be in fluid communication with a drain of a plumbing fixture and a second inlet; and a cleaning and maintenance assembly, integrally formed with the drain trap, and including: a maintenance-assembly inlet, adapted to be in fluid communication to a source of pressurized liquid; a maintenance-assembly outlet in fluid communication with the second inlet; a pipe disposed between the maintenance-assembly inlet and the maintenance-assembly outlet; an electronic valve having an open state allowing flow of liquid, from the maintenance-assembly inlet to the maintenance-assembly outlet, through the pipe, and a closed state blocking flow of liquid from the maintenance-assembly inlet to the maintenance-assembly outlet; an electronic controller adapted to transition the electronic valve between the open state and the closed state; and a power source adapted to power the electronic valve and the electronic controller, wherein, when the maintenance-a
• Embodiment 49 The drain device of embodiment 48, wherein the drain trap includes a drain trap cap, disposed at a lower end thereof, and wherein the electronic valve, the pipe, and the maintenance-assembly outlet are disposed within the drain trap cap.
• Embodiment 56 The drain device of any one of embodiments 46 to 55, wherein the maintenance assembly further includes a communication interface, functionally associated with the electronic controller and adapted to enable delivery of control inputs from a remote control unit to the electronic controller.
• Embodiment 57 The drain device of any one of embodiments 46 to 56, wherein the electronic controller is programmable.
