Definitions

  • the present invention relates to an automatic disinfection installation for the flow conduits of sanitary appliances, comprising at least one reservoir of a liquid bactericidal substance, at least one diffuser for introducing this substance directly or indirectly into said conduits, a pump supplied for controlling said diffuser and means for momentarily switching on said pump.
  • Such a device is for example described by the French patent application published under No. 2,445,416, relating to an automatic disinfection installation of a flow device for a sink or the like.
  • This installation comprises an aerosol can and a control device equipped with a water pump which actuates the valve of the aerosol can at each flow of water through the tap of the sink.
  • This device has various drawbacks due in particular to the low capacity of aerosol cans, to the nuisance caused by the pressurized gas contained in these cans, to the danger of explosion represented by these cans in certain industrial environments where the temperature can reach or even exceed 50 ° C, as well as the problem of mounting the water pumps.
  • the present invention proposes to overcome all the drawbacks mentioned above by providing a compact device, easy to install and adapt to any sanitary appliance and for which it is possible to determine with precision both the duration of the spread of the bactericidal substance and the precise time of this spread, so that it effectively protects the sanitary facilities against dangerous bacterial overgrowth.
  • the automatic disinfection installation of the flow conduits of sanitary appliances as defined above is characterized in that said means for momentarily engaging said pump comprise at least one detector member arranged to detect the evacuation of waste water through said conduits of said sanitary appliances, and means for transmitting a detection signal to a control circuit of said diffuser supply pump.
  • control circuit includes timing members for defining the duration of a time interval between the detection of the start of the discharge of wastewater and the start of the spread of the bactericidal substance. Furthermore, the control circuit advantageously includes timing members for defining the duration of the diffusion phase of the bactericidal substance.
  • the detector member comprises at least one microphone and the means for transmitting a detection signal to the pump control circuit comprise at least one amplifier.
  • the detector member preferably consists of a contact probe comprising two electrodes mounted at least partially inside a flow circuit of a sanitary appliance.
  • the detector member may comprise a thermal probe mounted at least partially inside a flow circuit of a sanitary appliance, at least one reference probe and the means for transmitting a detection signal to the control circuit of the supply pump of the diffuser may comprise at least one member sensitive to a temperature difference appearing between said thermal probe and said reference probe.
  • the diffuser is advantageously mounted in such a way that the bactericidal substance can be sprayed or sprayed into the flow conduits of one sanitary appliance.
  • the sprinkler (s) can be arranged in the overflow evacuation pipe, near a siphon or even inside the water tank of a toilet bowl. In this case, the bactericidal substance is mixed with the rinsing water from this bowl.
  • the detector member and in particular the contact probe can be mounted at least partially in a flow conduit or inside the water tank of a toilet bowl. In this case, it detects a drop in level in this tank.
  • the installation shown comprises a box 1 consisting for example of a metal box, of synthetic material or of any other suitable material, divided into two compartments 2 and 3 by a partition wall 4.
  • the compartment 2 is designed to accommodate a container 5, for example a glass vial containing the bactericidal substance 6.
  • the compartment 3 advantageously contains a pump 7, a step-down transformer 8 for supplying the pump 7, a step-down transformer 9 for feeding the detector organ (s) and an electronic control circuit 10.
  • the pump 7 is connected to the bottle 5 containing the bactericidal substance 6 by a tube 11 whose free end plunges into the bottom of the bottle 5.
  • the pump is also connected by a conduit 12 to the diffuser 13 , which in this case is in fact a double diffuser (illustrated in more detail in FIG. 2) intended to inject bactericidal substance inside the overflow duct 14 d 'a sink 15 and towards the drain 16 of this same sink.
  • a microphone 17 picks up the noise caused by the flow of water to the drain 18 of the sink, and constitutes the detector member supplied by the transformer 9 through the line 19.
  • This detector organ transmits a detection signal amplified by an amplifier 20 to the electronic circuit 10 through the line 21.
  • the electronic circuit 10 preferably comprises timing members which allow a part of determining the zero instant of the diffusion of bactericidal substance, that is to say the time interval which elapses between the start of the detection of the flow of waste water through the discharge conduit 18 and the switching on of the pump 7 which supplies the diffuser 13, and on the other hand the duration of the disinfection phase, that is to say the operating time of the pump 7.
  • Fig. 3 shows a variant according to which a bactericidal substance ejection nozzle 40 is mounted laterally on the siphon 41 of a sink or any other sanitary appliance such as a bathtub, bidet, etc.
  • the diffuser 40 is substantially arranged in the extension of the evacuation duct 42 of this sanitary appliance.
  • a contact probe 43 is fixed to the external wall of the discharge pipe 42. This probe has two electrodes 44 and 45 which penetrate inside the discharge pipe 42. When the wastewater is discharged, the two electrodes 44 and 45 are short-circuited, which provides a detection signal retransmitted to the electronic circuit (not shown).
  • Fig. 4 illustrates another embodiment of the disinfection of a toilet bowl 50 equipped with a water tank 51.
  • the detector member is constituted by a contact probe or a level detector 52 housed at inside the tank 51.
  • the water level drops in the tank 51, which generates the detection signal picked up by the electronic circuit.
  • a diffuser 53 is arranged near the back wall of bowl 50.
  • Fig. 5 illustrates a variant of the embodiment described with reference to FIG. 4.
  • the diffuser 60 is housed inside the tank 51 and the bactericidal substance intended for disinfecting the toilet bowl is previously mixed with the rinsing water contained in the tank 51.
  • the box containing the bottle of bactericidal substance and the control members can be equipped with a window for detecting the level of substance contained in the bottle and / or with an access door to the control members.
