Definitions

  • the present invention relates to a hygienic device for automatic dispensing of liquids.
  • an automatic liquid distributor is constituted as follows, with reference to a consumption distributor.
  • This receiving bowl is usually supplied by a pipe bringing the solvent, in general hot or cold water and there is also at the bowl a pipe or other type of pipe bringing as the case may be a liquid concentrate such as a syrup, or solid such as a powder, for example a lyophilisate such as soluble coffee.
  • the conduits are themselves connected to receptacles (boiler, refrigerator, concentrate tank, etc.) and include electrically controlled valves, electrovalves or taps, and if necessary pumps to circulate the flows.
  • the bowl receives both the solvent, for example hot water and the product to be dissolved, for example lyophilized coffee; both are mix in the bowl and feed the cup.
  • the pipe which brings the mixture from the bowl to the cup and the bowl itself which are the seat of a bacterial proliferation which is all the more significant for the dissolved product is syrupy and the temperature of the enclosure is important.
  • Regular, irregular, absent or poorly done manual washing does not solve hygienic problems. Indeed, the sources of bacterial development are multiple and linked to the geographic location of the device, generally in an unprotected environment, the fact that products often use sugar, the fact that the devices give off heat and / or vapor, and in particular to human contact during filling and technical handling.
  • an automatic dispensing device for liquids, in particular for consumption which is particularly hygienically safe.
  • this device should take into account the time, the human interventions carried out in the device, the possible breakdowns or stops of the automatic distributor and finally it should not present any risk for the consumer.
  • the present application relates to a hygienic device for automatic distribution of liquids comprising at least one bowl receiving a concentrate and an inlet for a solvent for the concentrate, characterized in that it comprises an inlet for an active product. on pathogenic germs in said receiving bowl.
  • liquid any liquid sleeping the distribution must be healthy, in particular the distribution of consumption or drinks, both to humans and to animals. It can also be a liquid for hospital use.
  • concentrate a concentrate both liquid such as a syrup, for example a lemon syrup, grenadine syrup, strawberry syrup or other, than a solid concentrate such as a lyophylisate, for example coffee or freeze-dried tea or even soluble powders such as tomato soup.
  • solvent the solvent for the concentrate, for example cold water in the case of lemon syrup or hot water in the case of lyophilized coffee.
  • the active product can arrive at the level of the bowl for example by gravity, if its reservoir is located above the bowls, or can be propelled using a pump if desired.
  • the active product may be of any type compatible with the liquid that it is desired to distribute. It could be a single substance or a mixture of substances.
  • bactericides, fungicides or molecules having both activities can be used. These molecules could belong to all the chemical families and in particular to the amines and quaternary ammoniums.
  • These products will preferably be non-toxic and non-corrosive, in particular with respect to common materials. Mention may be made in particular of the synergistic association of laurylpropylenediamine and of lauryl dimethyl benzylammonium bromide sold under the name of Biosept.
  • the above device is characterized in that the arrival of the active product is controlled by a programmer.
  • the active ingredient generally constitutes a protective film which prevents bacterial proliferation.
  • the device described above advantageously comprises an apparatus controlling a rinsing operation using a rinsing liquid after each arrival of active product.
  • the rinsing liquid may be of any suitable nature, but it will generally consist of hot or cold water. Hot water is preferred in the case of a bowl for dispensing hot drinks and cold water possibly preceded by rinsing with hot water for bowls intended for dispensing cold drinks.
  • the programmer will generally control the arrival of the active product at fixed intervals, for example every 12 hours.
  • FIG. 1 is a schematic representation of the circulation of fluids in a device according to the present invention
  • FIG. 2 represents the electrical diagram of controls of a device according to the present invention
  • FIG. 3 represents the electrical power diagram of a device according to the present invention.
  • FIG. 1 we can see the cup 1 into which the liquid will be poured, the pipes 2 allowing the filling of the cup 1 from the bowls 3, the pipes allowing the supply of the different bowls with hot water 4A, 4B and in cold water 4C and 4D.
  • the solvent supply to the various bowls is controlled by the solenoid valves 5 from solvent tanks, here hot water tank 6 and chilled water tank 7; the boiler and the refrigeration system are not shown here, as is the supply of these tanks.
  • Two solenoid valves are not used; they are available if you want to distribute three liquids instead hot or three cold liquids rather than two of each.
  • the pumps 8 enabling the bowls 3 to be supplied with active products, for example a bactericide / fungicide, the reservoir 9 for active product and the arrivals 10 for active product in the bowls.
  • H denotes the programmable weekly clock, it supplies the relay Z with a contact h at each cycle start, for example every twelve hours. This contact h remains actuated for an adjustable time t1.
  • Z designates the cycle start relay.
  • R designates the relay for the active product pump (s).
  • S designates the safety relay; it prohibits the use of the dispenser during the class cycle.
  • T indicates the relay allowing the supply of U.
  • U designates the relay which directly supplies the solenoid valves of the machine.
  • L indicates the indicator light which indicates that the machine is injecting active products.
  • Rth1 designates the time delay of R. Rth1 determines the supply of R during a time a. a is therefore the time during which the pumps injecting the active product are actuated.
  • Rth2 determines the time delay of T, therefore the supply of U which conditions the duration of the supply of the bowls with rinse aid, here water, via the solenoid valves. Furthermore, Z1 is the contact of Z which supplies R, Z2 the contact of Z which supplies S, T1 the contact of T which supplies S, R1 an inverted contact, T2 the contact which supplies U and S1 the contact which supplies the indicator .
  • U represents the direct supply of the solenoid valves of the machine
  • EV represents the solenoid valves
  • Y represents a manual control of bactericidal injection
  • R2 represents the contact of relay R which supplies the pump
  • X is a switch connected to a pressure switch sensitive to the supply of flushing liquid in the event of a cut or insufficient pressure the cycle is blocked.
  • S2 Gob is the security system which prohibits the use of the dispenser during the cycle of the hygienic device
  • S3 Kit the security system to prohibit the use of the dispenser when it is fitted with a button for dispensing hot or cold water.
  • a cycle comprises first of all an injection of a certain volume of active products, then a rinsing optionally with the solvent, and if desired a second rinsing optionally with the same solvent or a different solvent, and which may be at a different temperature.
  • the relays H, Z, S, R, T, and U are at rest.
  • the system is initialized by rinsing all the bowls for a time b; at this time the relays H, Z, and R are at rest and the relays S, T, and U are actuated.
  • An instant after the system is initialized and all the relays are at rest.
  • the pumps are actuated for a time a; at this time the relays T and U are at rest while the relays H, ZS and R are actuated.
  • a is of the order of 5 seconds to two minutes generally for a bowl of 10 to 40 cl; approximately 20cl of active product solution are thus discharged.
  • the relay R is at rest while the other relays are actuated, which corresponds to the rinsing operation which lasts from 30 seconds to 3 minutes.
  • the volume delivered is preferably 5 times the volume of the solution of the active product.
  • you may wish to carry out an additional consecutive rinse for example with cold water, in particular for bowls delivering a cold liquid.
  • the relays R, T and U are at rest then that relays H, Z and S are actuated. The machine then remains unusable for a period t1.
