Definitions

  • the present invention relates to an electronic assembly for controllably delivering disinfectant liquid and the like into sanitary apparatus in general.
  • the water upon entering the mixing chamber, also enters a communicating compartment, where there is arranged a metering valve system which introduces into the water entering the mixing chamber a dose of liquid disinfectant.
  • the water which is present in the mixing chamber, together with the disinfectant present therein, is sent to the sanitary apparatus.
  • This construction does not allow to perform a precise metering operation, since the disinfectant is mixed as water is introduced into the mixing chamber, thereby the metering operation can be affected by errors due to a surging in the water supplied to the mixing chamber.
  • the amount of disinfectant being introduced can not be accurately determined or controlled.
  • the document EP-A-0 338 825 discloses an electronic assembly for controllably delivering disinfectant liquids and the like into a sanitary apparatus having the features of the pre-characterizing part of the main claim.
  • the aim of the present invention is that to solve the above mentioned problem, by providing an electronic assembly for controllably delivering disinfectant liquids and the like into sanitary apparatus in general, adapted to meter a preset amount of disinfectant liquid into a mixing chamber, said disinfectant liquid being mixed at the use time with a portion of water taken from a water delivery duct, thereby providing a water delivery to the sanitary apparatus as the water through the delivery duct ends.
  • a main object of the present invention is to provide such an electronic water delivery assembly which is able of metering, in a very precise and accurate manner, the amount of disinfectant liquid, independently from the water flow passage conditions.
  • Another object of the present invention is to provide such an electronic assembly for controllably delivering disinfectant and the like liquids which, owing to its constructional features, is very safe and reliable in operation.
  • an electronic assembly for controllably delivering disinfectant liquids and the like into sanitary apparatus in general having the features of the characterizing part of the main claim.
  • the electronic assembly for controllably delivering disinfectant liquids into sanitary apparatus in general comprises a mixing chamber, indicated generally at the reference number 1, which communicates, at the bottom thereof, through a communicating duct 2, with the water delivery duct 3.
  • the communicating duct 2 is arranged so as to present a port 4 thereof facing the delivery water outflow direction, so as to take up a portion of this water and introduce it into the mixing chamber.
  • a water flow breaking element 6 which has a mixing chamber communicating port 7 arranged at a given distance from the bottom thereof.
  • the mixing chamber 1 in particular, is closed at the top thereof by a resiliently deformable membrane 10, which separates the mixing chamber 1 from an expansion compartment 11, communicating with the outside atmosphere, where an electric contact 12 is provided to be operated or driven, as-it will become more apparent hereinafter, by the expansion of said membrane 10, as the water level inside the mixing chamber 1 is raised.
  • the electric contact 12 drives the operation of a roller metering pump 20, which comprises a pump impeller 21 provided, on its periphery, with a set number of rollers 22, evenly spaced, which operate to press a resilient hose or pipe 23 communicating with a disinfectant liquid holding tank 24 and leading, at the other end thereof and through a discharging duct 28, to the bottom of the mixing chamber 1.
  • a roller metering pump 20 which comprises a pump impeller 21 provided, on its periphery, with a set number of rollers 22, evenly spaced, which operate to press a resilient hose or pipe 23 communicating with a disinfectant liquid holding tank 24 and leading, at the other end thereof and through a discharging duct 28, to the bottom of the mixing chamber 1.
  • the delivery water, or bowl washing water, conveyed through the communicating or fitting duct 2 will enter the mixing chamber, thereby the water level therein will gradually rise.
  • the water held in the mixing chamber will upwardly press against the membrane 10 which, upon expanding, will enter the top chamber or expansion bowl which, as stated, communicates with the atmosphere.
  • the pressure exerted by the resilient membrane in the top portion of the expansion bowl will cause an electric contact to trip, so as to energize an electronic circuit controlling the operation of the metering pump 20, which will simply a preset dose of disinfectant liquid, adapted to kill any bacteria in the sanitary apparatus.
  • the metering pump has a half-cylindrical shape and, in the bottom inner portion of its circumference there is defined a half-cylindrical portion which will firmly hold the resilient hose or pipe.
  • the wheel impeller comprises a spider element having either two, three, four or more ends on which there is provided a respective roller pressing the resilient hose to cause the liquid to flow therethrough.
  • This impeller is rigid with the rotary shaft of the speed reducing unit which transmits the rotary drive through a pin element 30.
  • This pin element or reset pin 30 has the two functions of causing the wheel spider to turn and causing the pump to stop at the end of its operation.
  • the inner air is pressurized so as to deform or expand the above mentioned resilient membrane 10.
  • the delivered water will continuously flow to the sanitary apparatus and the pressurized air in the mixing chamber will cause the membrane to be further expanded so as to complete the mixing step and actuate the electric contact.
  • the solution held in the mixing chamber will flow to the sanitary apparatus thereby properly disinfecting the latter.
  • disinfectant liquid is again introduced into said mixing chamber by the metering pump which is actuated to draw the disinfectant liquid into the flexible hose and deliver this disinfectant liquid to the bottom of the mixing chamber, ready for a further use.
  • the used materials, as well as the contingent shapes and size can be any according to requirements.
