Definitions

  • This invention concerns a tap capable of automatically delivering water cold, hot or mixed to a preselected temperature when hands or other body parts are placed beneath it.
  • taps for wash basins and bath tubs as well as delivery systems for showers and kitchen sinks have one or more handles to regulate the flow, leading to wasted water since they continue delivery even during the soaping operations, etc., in which the spray emitted is not directly used.
  • hot or mixed water not only water is wasted but above all the energy used to heat it.
  • the aim of this invention is the realization of water delivery taps of every type able to function automatically with no intervention with regulation handles, thus simplifying and speeding up each washing operation. At the same time, said taps can also limit water delivery to that strictly necessary, with evident energy savings in the case of hot or mixed water.
  • This aim is achieved with a tap equipped with a sensor consisting of an emitter of infrared rays, photodiode or phototransistor next to a corresponding receiver such that, in rest conditions, the ray emitted and reflected by the inner surface of the wash basin or the like does not reach said receiver be-cause the distance like does not reach said receiver because the distance is too great, keeping the delivery of cold, hot or mixed water off.
  • the infrared ray sensor may be replaced with an analogous ultrasonic device consisting of an emitter and receiver next to one another.
  • the senor may consist of a capacitive, inductive or capacitive-inductive device.
  • the senor may consist of a microwave or electromagnetic wave emitter and detector.
  • a general variant, valid for rthe systems described (operating with side by side sensors), consists of a system of opposite sensors, which does not change the operation of the device.
  • the electronic detection and control group for operating the electrovalves involves a stabilized supply, an emitting oscillator, an emitter, a receiver, a potentiometric trimmer acting on the amplification of the receiver which regulates the distance of the interfering ray.
  • the information consisting of the reflected infrared ray, is amplified in the receiver.
  • the emitter is fitted with a network of resistors and capacitors which allow the operation phases to be slowed down, preventing immediate starting and stopping be- cause of brief removal of the hands or bodies during the wash operation.
  • other amplifiers are connected with a power group, preferably consisting of a relay.
  • the relay (or other device) operates one electrovalve (in the case of cold water) or two (for hot and cold water, connected in parallel in this case) which allow water to pass.
  • a mixer which may be manual, mechanical, sintered disk, thermostatic, electromechanical, or any other type.
  • the body of the tap is indicated with 1, made of plastic or other suitable material, bearing the infrared sensor consisting of the emitter 2 and receiver 3, next to one another and installed near the opening 10 for water outlet.
  • the electronic group is indicated with 5, the capacitor with 6, the electrovalves with 7, with tubes 8 and 9 for hot and cold water intake into':the mixer 4, with plastic or other type tube 11 to conduct the mixed water to said outlet opening 10.
  • the scheme in figure 4 shows the stabilized source, the oscillator 13, the amplifiers 14, the cut off delay 15 and the power group 16.
  • receiver 3 captures a signal from the emitter 2, after reflection on the hands placed under the outlet opening 10, within its capture ray, it leads to passage to the amplifiers 14, so that the power group 16 is excited and feeds the two parallel electrovalves 7 and causes water to be sent to the mixer 4 and so to the user.
  • the R-C net 15 retards stoppage for approximately 2 seconds after the hands or objects are removed from the perception of sensors 2 and 3.
