Definitions
- the present invention relates to automatic cleaning installations for kitchen extractor hoods, which use a treatment solution containing non-pathogenic micro-organisms capable of degrading in particular fats or oils from cooking vapors or fumes.
- the present invention provides an original cleaning installation aimed at remedy these various drawbacks.
- the installation according to the present invention comprises at least one nozzle misting venturi, provided with means which allow its attachment to a wall of the range hood that you want to equip, which nozzle is connected to an air source tablet and a supply of treatment solution to ensure aspiration automatic of said solution and its diffusion in the form of mist in said hood, said source of compressed air being controlled by a scheduling system allowing to program one or more cleaning sequences outside the kitchen use periods.
- the structure of this installation is very simple; and the use of a nozzle misting venturi ensures atomization of the treatment solution particles to form a mist inside the hood, giving the cleaning system optimal efficiency and limiting the quantities of product required.
- the misting venturi nozzle is fixed to one of the walls of sides of the hood.
- the installation comprises - an air source compressed in the form of an electric compressor unit connected to the venturi nozzle of misting by means of an air intake tube, and - a reserve of solution of treatment connected to said nozzle by means of a liquid supply pipe.
- the supply pipe of the solution to be injected ends up at the venturi nozzle under the air supply pipe, to favor the return by simple gravity of the treatment solution in the reserve when the power unit stops, and the said nozzle is emptied.
- the reserve of treatment solution, as well as the compressor unit are arranged at the same horizontal level or substantially the same horizontal level as the venturi nozzle, in particularly to limit pressure losses.
- the installation includes means which allow manual initiation of a hood cleaning sequence; these means are advantageously in the form of a switch mounted in parallel with the programming system.
- the compressor unit, the programming system and possibly the switch to manually trigger cleaning are located in a box-shaped module placed next to the solution tank treatment, the assembly being positioned near the hood in an adjoining room appropriate.
- an electric pump can be used to favor the supply of the treatment solution to the venturi misting nozzle; this pump is advantageously supplied with electricity after the system programmer so as to be activated simultaneously with the compressor unit.
- the attached figure shows an extractor hood 1 placed above a piano 2 and equipped with the cleaning device 3 according to the present invention.
- the hood 1 comprises a longitudinal covering 4 closed by side walls 5 and by a bottom face 6.
- the longitudinal covering 4 is generally made of stainless steel sheet, just like the side walls 5; the underside 6 may be in the form of a grid associated with a filter system (s).
- This hood 1 incorporates a turbine-shaped ventilation system, not shown, which allows the suction of fumes, vapors and the like coming from the cooking piano 2 by the underside 6, and which allows their evacuation by an outlet duct. 8, generally placed in the center of the longitudinal covering 4.
- the cleaning device 3 consists of a system injector 10 in the form of a venturi misting nozzle, of the air / liquid type, connected, of a firstly, to a reserve 11 of treatment solution 12, and secondly to an air source compressed 13 whose power supply is controlled by a system programmer 14.
- the venturi nozzle 10 is fixed inside the hood 1, on one of its side walls 5, for example in the center of said wall. It is suitable for atomizing the treatment solution 12 in the air and thus forming a mist of treatment liquid in the internal volume of the hood.
- This nozzle 10 is connected to the liquid reservoir 11 by a supply pipe 15, and to the source of compressed air 13 by a supply pipe 16. These two pipes 15 and 16 are advantageously made of copper.
- the arrival of the supply pipe of liquid 15 is placed under the inlet of the compressed air supply pipe 16, to favor the return of the treatment liquid 12 in the reserve 11, and the emptying of said nozzle 10, when the compressed air source 13 stops.
- the treatment solution 12 placed in the reserve 11 in the form of a bottle is a “ready-to-use” biotechnological solution containing non-pathogenic microorganisms capable of degrading the particles of grease, oil and others originating from cooking fumes or vapors. , and which are deposited on the internal walls of the hood, or on the integrated accessories (filter (s), turbine, outlet duct). These microorganisms ensure the transformation of fats into assimilable elements in the natural biological cycle and cause a separation of the carbon chain thus making the residues soluble in water.
- the liquid in question is advantageously a solution of microorganisms "ready to use” marketed under the name "NU VENT" (Trademark registered by the MIKAAN Group), by the Company INNU-SCIENCE, Boulevard Nobel, Sainte-JULIE QUÉBEC - CANADA .
- the bottle / reserve 11 can have a capacity of the order of 4 to 20 liters.
- the source of compressed air 13 is in the form of an electric compressor unit supplied by means of a cable 18 connected to the sector 19.
- the connection of the cable 18 to the sector 19 takes place via the programming system 14 and a switch 20, mounted in parallel.
- the compressor unit 13 can be of the piston type; it allows the sending into the tube 16 of an air flow at a rate of the order of 30 liters per minute.
- Switch 20 allows manual triggering, at will, of hood cleaning sequences.
- the scheduler system 14 makes it possible to program one or more cleaning sequences over time, in particular outside the periods of use of the kitchen, for example at the end of each day, or at night.
- the programmer 14 can be a very simple system of standard type, provided with male pins allowing the connection to a conventional electrical outlet, and female pins allowing the reception of the connection cable coming from the compressor unit. Programming is carried out using a control keyboard located on the front of the device.
- the compressor 13, the switch 20 and the programmer 14 are advantageously placed in a receiving box 21 positioned next to the tank 11 of treatment liquid 12.
- the liquid reservoir 11 and the box 21 are arranged near hood 1, if possible in an appropriate annex room (the bulkhead corresponding separator is shown schematically by the dotted line 22).
- the bottle 11 of treatment solution is located at the same level or substantially at the same level as the misting nozzle 10, that is to say in the same horizontal plane, or substantially in the same horizontal plane, just like the compressor unit 13, so as to limit pressure losses as much as possible.
- an electric pump 23, of the peristaltic type can be placed on the pipe 15, supplied with electricity after the switch 20 or the programmer 14 to be activated simultaneously with the compressor unit 13.
- outlet duct 8 is not centered on the length of the hood 1, it will be preferable to fix the misting nozzle 10 on the side wall 5 furthest from said duct 8, to optimize the distribution of the treatment solution. In any event, and depending on the needs, it is possible to envisage equipping the hood 1 with a plurality of nozzles 10.
- the programmer 14 can for example be configured to carry out product injections for a few minutes each day after service. Through example, we can consider misting times between 3 and 15 minutes per day. This type of treatment can lead to a reasonable consumption of treatment product, of the order of 50 to 150 ml per day, which makes it possible to obtain a permanently clean and odor-free hood interior at a very low cost interesting. In any event, the duration of treatment will depend on the size the hood and its clogging. Internal residues are removed by ventilation.

Abstract
Description
Cette hotte 1 intègre un système de ventilation en forme de turbine, non représentée, qui permet l'aspiration des fumées, vapeurs et autres provenant du piano de cuisson 2 par la face de dessous 6, et qui permet leur évacuation par un conduit de sortie 8, placé généralement au centre de l'habillage longitudinal 4.
Cette buse 10 est reliée au réservoir de liquide 11 par une tubulure d'amenée 15, et à la source d'air comprimé 13 par une tubulure d'amenée 16. Ces deux tubulures 15 et 16 sont avantageusement réalisées en cuivre.
Le liquide en question est avantageusement une solution de microorganismes « prêt à l'emploi » commercialisée sous la dénomination « NU VENT » (Marque déposée par le Groupe MIKAAN), par la Société INNU-SCIENCE, Boulevard Nobel, Sainte-JULIE QUÉBEC - CANADA. Le flacon/réserve 11 peut avoir une contenance de l'ordre de 4 à 20 litres.
Le groupe motocompresseur 13 peut être du type à piston ; il permet l'envoi dans la tubulure 16 d'un flux d'air à un débit de l'ordre de 30 litres par minute.
Le programmateur 14 peut être un système très simple de type standard, muni de broches mâles permettant la connexion à une prise électrique classique, et de broches femelles permettant la réception du câble de branchement provenant du groupe motocompresseur.
La programmation s'effectue à partir d'un clavier de commande situé sur la face avant de l'appareil.
En tout état de cause, et en fonction des besoins, on peut envisager d'équiper la hotte 1 d'une pluralité de buses 10.
