Definitions

  • This invention relates to a self-closing mechanical faucet with an ergonomically convenient and manually adjustable flow-control for intermittent outflow use to reduce fluid wastage.
  • Faucets at the sinks in public washrooms are often fitted with special valves or devices that prevents wastage of water by people forgetting to turn off the water tap after use or by using an unnecessarily large amount of water.
  • Most mechanical faucets of these types usually operates using intermittent flows that restricts the user to a fixed amount of water each time the faucet valve-control knob or stem is manually pushed and released, therefore the user has hardly any control of the outflow rate. If more water is required to continue washing, one hand must be used to repeatedly press and release the faucet control that is usually placed above the water outlet spout.
  • Other water-saving faucet designs have the valve-control manual contact tip too close directly below the faucet spout orifice to be continuously pressed or pulled while washing both hands at the same time.
  • the present invention aims to provide a useful alternative to known self-closing mechanical faucets for washing using intermittent outflow to reduce fluid waste. This is achieved by placing the faucet valve-control which must be pressed or pushed for fluid outflow near enough to the faucet outlet spout but not in the path of the outflowing fluid so the valve-control that is user-adjustable for variable outflow rate can be conveniently reached by the person's hand, wrist or forearm while the hands are being washed in the fluid flowing out of the faucet spout.
  • the ergonomic position of the lever handle or knob of the faucet valve-control is located in a region of space (FIG. 1) beside the path of the outflowing fluid from the faucet spout 1 termed as Control Region 5.
  • this valve-control lever is inclined towards the user so that it can be easily pressed or pushed by the hands, wrist or forearm that may be being washed under the faucet outlet 1, so the distance of the perimeter radius D of this region from the outlet of the faucet spout is about the width of a human hand span that is approximately 15-25 centimeter, and both the double-arrow in FIG. 1 is pointing towards the user. Since the same washing hand is conveniently interacting with the faucet valve the user is able to actively adjust the outflow rate according to his requirement thereby attaining ergonomic feedback control of the fluid outflow. The manual release of this faucet valve-control after usage will immediately or slightly later stop the outflow of fluid hence reducing unnecessary fluid loss. An option, is to interrupt this self-closing function with a releasable restrain to be latched if required by the user, although this will interfere with its fluid-saving feature.
  • This example is made from a faucet valve that will fully open through a turn of the faucet valve-control by rotating it 90° from the close position.
  • This type of ceramic valve 7 (FIG. 6) is available from plumbing suppliers nowadays.
  • a torsion coil spring 8 is attached to the rotatable valve stem-rod 9 and valve body so that there is a torque on the valve stem 9 and control lever handle towards the close direction. It is preferable that this counteracting torsion spring does not rust.
  • This torsion spring-closed valve 10 is placed inside the faucet valve rotatable housing 3 (FIG.
  • the axis of rotation of the faucet lever may be angled pointing 5° - 80° (FIG. 3) to the right from the direction towards the user. Additionally this axis may also be slightly tilted away from the horizontal.
  • the normally closed position of the lever may incline 0° - 70° from vertical (FIG. 4) depending on the mains pipe water pressure so that the contact tip of the lever handle 2 when normally closed is at a position about towards the user.
  • valve-control lever When the user pushes the faucet lever handle stem it will rotate downwards anticlockwise and is adjusted such that the desired flow rate is achieved when the tip of the lever 2 is at a position slightly lower than the level of the faucet outlet spout that is in the Control Region 5.
  • the valve-control lever will usually need to rotate through an angle that is less than the 90 degrees angle limit for the fully open position especially when the water pressure in the pipe 4 is high, therefore it is possible to rotate the control lever even further for greater outflow rate if desired. Since the hand that presses the valve-control lever will usually move about while it is being washed, there is a tendency to unintentionally push the lever further causing to splash too much water due to excessively high outflow rate.
  • valve-control lever when at the open- position where the lever angle at the desired optimum flow rate is attained, the valve-control may be mechanically stopped to prevent further rotation or another stronger counteracting spring which requires a larger torsion force is contacted to stiffen any further lever rotation so that it is manually much more difficult to increase the outflow rate and thus tends to hinder accidental over-rotation.
  • FIG. 1 shows the region of space defined as Control Region 5 where the ergonomic valve-control lever handle contact tip must be located to conveniently turn on and adjust the self- closing intermittent flow faucet.
  • the top plane boundary surface of this Control Region space 5 is at about the faucet spout opening level perpendicular to the spout outflow direction and also extends behind the faucet outlet spout 1.
  • the dash lines shows the path of the outflowing fluid from the faucet outlet spout.
  • FIG. 4 is the same faucet as above that has been manually released and its similar shaped lever handle is at the fully spring-closed position viewed from the right.
