Description

La présente invention concerne un dispositif assurant de façon automatique la désinfection de la cuvette et du siège d'un W.C., avant la mise à la disposition d'un usager.The present invention relates to a device providing automatic disinfection of the bowl and the seat of a toilet, before making it available to a user.

A l'époque actuelle, toute personne est amenée fréquemment à utiliser des W.C. à usage collectif en des occasions diverses de la vie courante, par exemple sur les lieux du travail, lors des voyages (soit dans les moyens de transport tels que le train, le bateau ou l'avion, soit dans les gares ou aérogares, soit encore sur la route par exemple dans les lieux de parcage ou les stations-service), ou encore dans les lieux de distraction et de détente (théâtres, restaurants, etc ...). Il est important, pour des raisons d'hygiène évidentes, que ces usagers puissent être toujours assurés de trouver les appareils sanitaires de ces W.C. collectifs, et en particulier les cuvettes et sièges de W.C., en parfait état de propreté et de désinfection même si, comme c'est la plupart du temps le cas, du personnel n'est pas disponible à tout moment pour en assurer le nettoyage.At the present time, every person is frequently brought to use toilets for collective use on various occasions of everyday life, for example at work, during trips (either in means of transport such as the train, the boat or the plane, either in the stations or terminals, or still on the road for example in the places of parking or the service stations), or in places of distraction and relaxation (theaters, restaurants, etc. ..). It is important, for obvious hygienic reasons, that these users can always be assured of finding the sanitary appliances of these collective toilets, and in particular the toilet bowls and seats, in perfect condition of cleanliness and disinfection even if, as is most often the case, staff are not available at all times to ensure cleaning.

Si, très souvent, la propreté de ces appareils sanitaires est assurée, par contre la plupart du temps rien n'est fait pour assurer de façon vérifiable leur désinfection.If, very often, the cleanliness of these sanitary devices is ensured, on the other hand most of the time nothing is done to ensure verifiable disinfection.

On a bien proposé d'employer des feuillets protecteurs en papier ou mélange de cellulose, présentant la forme de la lunette, dont l'usager peut revêtir la surface du siège et qu'il jette après emploi. Cette protection présente toutefois de nombreux inconvénients, d'une part parce qu'elle ne détruit pas les germes infectieux éventuels se trouvant sur le siège, d'autre part parce qu'elle ne concerne que le siège du W.C. et pas la cuvette, et aussi parce qu'elle n'a pas de caractère automatique et peut donc être négligée ou oubliée.It has been proposed to use protective sheets of paper or cellulose mixture, having the shape of the seat, which the user can cover the surface of the seat and which he discards after use. However, this protection has many drawbacks, on the one hand because it does not destroy any infectious germs present on the seat, on the other hand because it only concerns the toilet seat and not the bowl, and also because it is not automatic and can therefore be overlooked or forgotten.

On a aussi proposé de fixer, à l'intérieur du couvercle rabattable du siège de W.C., une lampe ou un tube à rayons ultra-violets dont l'alimentation électrique est commandée automatiquement dès que le couvercle est rabattu sur le siège et dont le rayonnement se trouve alors dirigé sur la surface de la cuvette ainsi que sur le siège en assurant une stérilisation de ces parties. Là encore, toutefois, les inconvénients entraînés par ce dispositif sont importants, d'une part en raison du danger présenté pour l'utilisateur par les rayonnements ultra-violets et, d'autre part, par les risques de détérioration dus à la fragilité des lampes ou tubes à rayons ultra-violets utilisés.It has also been proposed to fix, inside the folding lid of the toilet seat, a lamp or a tube with ultraviolet rays, the electric power supply of which is automatically controlled as soon as the lid is folded down on the seat and whose radiation is then directed on the surface of the bowl as well as on the seat ensuring sterilization of these parts. Again, however, the drawbacks caused by this device are significant, on the one hand because of the danger presented to the user by ultraviolet radiation and, on the other hand, by the risks of deterioration due to the fragility of the lamps or tubes with ultraviolet rays used.

Le document DE-A-26 21 802 décrit un dispositif automatique de désinfection comprenant des moyens de projection d'un liquide de désinfection portés par la face intérieure d'un couvercle destiné à être rabattu sur la lunette équipant le siège de W.C., ces moyens de projection étant constitués par une pluralité de têtes de diffusion qui font suite à un réseau de conduits incorporés dans le couvercle et reliés à un réservoir de produit chimique de désinfection sous pression, afin de pulvériser des jets de produit sur toute la surface interne de la cuvette et sur la face supérieure de la lunette. La projection de produit est commandée automatiquement pendant une durée limitée, lorsque le couvercle est rabattu en commandant la désinfection de la cuvette et de la lunette. Le couvercle comporte sur sa périphérie des moyens d'étanchéité pour son contanct, en position rabattue, avec le bord de la cuvette.Document DE-A-26 21 802 describes an automatic disinfection device comprising means for spraying a disinfection liquid carried by the inner face of a cover intended to be folded down on the seat fitted to the toilet seat, these means projection being constituted by a plurality of diffusion heads which follow a network of conduits incorporated in the cover and connected to a reservoir of chemical disinfection under pressure, in order to spray jets of product over the entire internal surface of the bowl and on the upper face of the bezel. The projection of product is controlled automatically for a limited time, when the lid is folded down by controlling the disinfection of the bowl and the bezel. The cover has on its periphery sealing means for its contanct, in the folded position, with the edge of the bowl.

La présente invention a pour objet de remédier aux inconvénients présentés par les dispositifs connus mentionnés ci-dessus et elle propose à cet effet un dispositif d'une grande simplicité de fabrication, d'un faible coût de revient et d'une grande efficacité de fonctionnement permettant à tout utilisateur d'obtenir de façon automatique, sans manoeuvre compliquée ni dangereuse, une totale désinfection de la cuvette et du siège du W.C. équipés de ce dispositif.The object of the present invention is to remedy the drawbacks presented by the known devices mentioned above and to this end it proposes a device of great simplicity of manufacture, of low cost price and of high operating efficiency. allowing any user to obtain automatically, without complicated or dangerous maneuver, a total disinfection of the bowl and the seat of the WC equipped with this device.

Selon l'invention, le dispositif automatique aus- surant la désinfection de la cuvette et du siège d'un W.C. comprend des moyens de projection d'un liquide de désinfection qui sont portés par la face intérieure d'un couvercle destiné à être rabattu sur la lunette équipant le siège de W.C., les dits moyens de projection étant constitués par une pluralité de têtes de diffusion faisant suite à un réseau de conduits incorporés dans le couvercle et reliés à un réservoir de produit chimique de désinfection sous pression, afin de pulvériser des jets de produit sur toute la surface interne de la cuvette et sur la face supérieure de la lunette, la projection du produit de désinfection étant commandée automatiquement pendant une durée limitée lorsque le couvercle est rabattu en commandant la désinfection de la lunette et de la cuvette, le couvercle comportant sur sa périphérie des moyens d'étanchéité pour son contact en position rabattue avec le bord de la cuvette, et ce dispositif se caractérise par le fait qu'il comporte des têtes de diffusion disséminées sur toute la surface intérieure et sur le bord périphérique du couvercle afin de pulvériser des jets de produit sur le siège et sur la face inférieure de la lunette, et que les moyens d'étanchéité portés par le couvercle sont constitués par un joint d'étanchéité qui, en position rabattue du couvercle, coopère avec la face extérieure de la cuvette en empêchant toute projection vers l'extérieur de produit désinfectant.According to the invention, the automatic device for disinfecting the bowl and the seat of a toilet comprises means for spraying a disinfection liquid which are carried by the inner face of a cover intended to be folded down on the seat fitted to the toilet seat, the said projection means being constituted by a plurality of diffusion heads following a network of conduits incorporated in the cover and connected to a reservoir of chemical disinfection under pressure, in order to spray jets of product over the entire internal surface of the bowl and on the upper face of the bezel, the spraying of the disinfection product being automatically controlled for a limited time when the lid is folded down by controlling the disinfection of the bezel and the bowl, the cover comprising on its periphery sealing means for its contact in the folded position with the edge of the bowl, and this device is characterized e by the fact that it comprises diffusion heads dispersed over the entire interior surface and on the peripheral edge of the cover in order to spray product jets on the seat and on the underside of the seat, and that the means of sealing carried by the cover are constituted by a seal which, in the folded position of the cover, cooperates with the external face of the bowl by preventing any projection towards the outside of disinfectant product.

Avantageusement le couvercle rabattable présente, en arrière de son axe de pivotement, un élément fixe en forme de boîtier conçu pour recevoir la tête de commande de pulvérisation du réservoir de produit désinfectant et dans lequel débouche une extrémité d'un conduit flexible destinée à s'adapter sur l'orifice de sortie de ladite tête de commande alors que l'autre extrémité de ce conduit coïncide, en position rabattue du couvercle, avec l'orifice d'entrée des conduits ménagés dans le couvercle. La partie inférieure de ce boîtier présente une ouverture dans laquelle on engage, par une porte latérale, le col du réservoir de produit désinfectant afin d'assurer la fixation de ce dernier, ce col présentant à cet effet un profil particulier en I. La partie supérieure du boîtier est ouverte pour permettre, lorsqu'on relève le couvercle, à un prolongement formant levier solidaire de ce couvercle d'engager alors la tête mobile de commande de pulvérisation du réservoir.Advantageously, the hinged cover has, behind its pivot axis, a fixed element in the form of a housing designed to receive the spraying control head from the reservoir of disinfectant product and into which opens one end of a flexible duct intended for adapt to the outlet orifice of said control head while the other end of this conduit coincides, in the folded position of the cover, with the inlet orifice of the conduits formed in the cover. The lower part of this box has an opening in which a neck of the disinfectant product reservoir is engaged by a side door in order to ensure the fixing of the latter, this neck having for this purpose a particular I-shaped profile. upper case is open to allow, when raising the neck circle, at an extension forming a lever integral with this cover, then engaging the mobile head for spraying the reservoir.

De préférence, on utilise un produit désinfectant à séchage pratiquement instantané, par exemple à base d'alcool ou d'agent frigorigène connu sous la marque "FREON", (marque commerciale déposée), et on peut prévoir de donner à la forme de la lunette une certaine courbure vers l'intérieur afin de faciliter l'écoulement vers la cuvette du produit pulvérisé sur la face supérieure de la lunette.Preferably, a disinfectant product is used which is practically instantaneous, for example based on alcohol or on a refrigerant known under the trademark " FREON " (registered trademark), and provision may be made to give the shape of the a certain curvature inward in order to facilitate the flow towards the bowl of the sprayed product on the upper face of the bezel.

On comprend que le couvercle, lorsqu'il est en position relevée, actionne par son prolongement la tête de commande du réservoir de produit désinfectant, mais à ce moment l'orifice d'entrée des conduits de pulvérisation ménagés dans le couvercle ne se trouve pas en regard de l'orifice de sortie du conduit flexible associé à la tête du réservoir (cet orifice de sortie se trouvant alors obturé par une partie pleine du couvercle) et le produit n'est donc pas pulvérisé. Lorsque le couvercle est ensuite rabattu, les deux orifices mentionnés ci-dessus viennent en regard l'un de l'autre et la pulvérisation est alors réalisée pendant un court laps de temps déterminé par un système de ressort qui agit sur la tête de commande pour rappeler celle-ci en position de repos. Ainsi, dans le cas où l'usager ne trouverait pas, à son arrivée, le couvercle rabattu en position de désinfection mais relevé, il lui suffirait alors de rabattre le couvercle et d'attendre un espace de temps très court, de quelques secondes, avant de relever ce couvercle et de disposer alors d'une cuvette et d'une lunette totalement désinfectées et parfaitement sèches.It is understood that the cover, when in the raised position, activates by its extension the control head of the disinfectant reservoir, but at this time the inlet orifice of the spray conduits formed in the cover is not located opposite the outlet of the flexible conduit associated with the head of the tank (this outlet is then closed by a solid part of the cover) and the product is therefore not sprayed. When the cover is then folded down, the two holes mentioned above come opposite one another and the spraying is then carried out for a short period of time determined by a spring system which acts on the control head to recall it in the rest position. Thus, in the event that the user does not find, when he arrives, the lid folded down in the disinfection position but raised, it would then suffice for him to close the lid and wait for a very short space of time, of a few seconds, before lifting this cover and then having a bowl and a fully disinfected and perfectly dry scope.

Pour bien faire comprendre le dispositif selon la présente invention, on en décrira ci-après une forme d'exécution préférée en référence au dessin schématique annexé dans lequel:

  • la figure 1 est une vue en plan d'une cuvette de W.C. équipée du dispositif de désinfection automatique selon la présente invention;
  • la figure 2 est une vue en coupe verticale de la cuvette de la figure 1; et
  • la figure 3 est une vue de côté, partiellement en coupe, montrant plus particulièrement le dispositif d'actionnement automatique du réservoir de produit désinfectant.
To clearly understand the device according to the present invention, a preferred embodiment will be described below with reference to the appended schematic drawing in which:
  • Figure 1 is a plan view of a toilet bowl equipped with the automatic disinfection device according to the present invention;
  • Figure 2 is a vertical sectional view of the bowl of Figure 1; and
  • Figure 3 is a side view, partially in section, showing more particularly the automatic actuation device of the disinfectant product tank.

Au dessin on a représenté en 1 la cuvette de W.C. sur le rebord supérieur ou siège 2 de laquelle vient s'appuyer la lunette rabattable 3. Autour d'un axe horizontal 4 s'articule, à sa partie arrière, un couvercle 5 présentant sur sa périphérie des rebords permettant à ce couvercle, lorsqu'il est dans une position rabattue représentée aux figures 1 et 2, d'envelopper la lunette 3. Sur sa périphérie, le couvercle 5 présente un joint d'étanchéité 6 réalisé en une matière résistant à l'agression des produits chimiques, et en particulier des produits de désinfection, et qui est conçu pour venir en contact étroit avec la surface périphérique extérieure de la cuvette 1 dans la position rabattue du couvercle 5.In the drawing there is shown at 1 the toilet bowl on the upper rim or seat 2 from which the folding bezel rests. Around a horizontal axis 4 is articulated, at its rear part, a cover 5 having on its periphery of the flanges allowing this cover, when it is in a folded position shown in Figures 1 and 2, to wrap the bezel 3. On its periphery, the cover 5 has a seal 6 made of a resistant material to the aggression of chemical products, and in particular of disinfection products, and which is designed to come into close contact with the external peripheral surface of the bowl 1 in the folded position of the cover 5.

Le couvercle 5 est réalisé en matière plastique moulée et il comporte, venus de moulage, des conduits 7 qui débouchent sur la face interne du couvercle par des têtes de diffusion 8. Ces têtes 8 sont disposées sur toute la face intérieure plane du couvercle 5 ainsi que sur les bords intérieurs recourbés de celle-ci de façon que, lorsque les conduits 7 sont alimentés en un produit désinfectant de la façon qu'on expliquera plus loin, les têtes 8 pulvérisent des jets de produit qui atteignent toute la surface intérieure de la cuvette 1, tout le siège 2 et la totalité des faces supérieure et inférieure de la lunette 3.The cover 5 is made of molded plastic and it comprises, from molding, conduits 7 which open on the internal face of the cover by diffusion heads 8. These heads 8 are arranged on the entire flat inner face of the cover 5 as well that on the inner curved edges thereof so that, when the conduits 7 are supplied with a disinfectant product as will be explained below, the heads 8 spray jets of product which reach the entire interior surface of the bowl 1, the entire seat 2 and all of the upper and lower faces of the seat 3.

Tous les conduits 7 d'alimentation des têtes de diffusion 8 aboutissent à un conduit principal 9 disposé à la partie arrière du couvercle 5 et ce conduit principal 9 débouche par un orifice 10 sur une partie arquée 11 de l'extrémité arrière du couvercle 5.All the supply ducts 7 for the diffusion heads 8 lead to a main duct 9 disposed at the rear part of the cover 5 and this main duct 9 opens out through an orifice 10 on an arcuate part 11 of the rear end of the cover 5.

A son extrémité arrière le couvercle 5 se prolonge par une partie fixe 12 en forme de boîtier ménageant une chambre intérieure 13 dont la paroi inférieure 14 est ouverte en 15. Dans cette ouverture 15 on engage latéralement le col d'un réservoir 16 contenant un produit désinfectant sous pression, de façon que la tête mobile 17 de commande d'éjection du produit soit logée à l'intérieur de la chambre 13 alors que le coprs du réservoir 16 s'étend sous le boîtier 12. Le col du réservoir 16 présente en section verticale une forme particulière en 1 avec des épaulements supérieur 18 et inférieur 18' qui s'engagent de part et d'autre de la paroi inférieure 14. Des ressorts 19 portés par la face inférieure de la paroi 14 engagent l'épaulement 18' du réservoir 16 pour assurer un bon maintien de celui-ci en position d'utilisation. Sur le côté le boîtier 12 est fermé par une porte, non visible au dessin, qui peut avantageusement être fermée à clef afin d'interdire l'accès au réservoir 16, en vue de l'enlèvement de celui-ci, à toute personne non autorisée.At its rear end, the cover 5 is extended by a fixed part 12 in the form of a housing providing an interior chamber 13, the lower wall 14 of which is open at 15. In this opening 15, the neck of a reservoir 16 containing a product is engaged laterally. disinfectant under pressure, so that the movable head 17 for controlling the ejection of the product is housed inside the chamber 13 while the body of the reservoir 16 extends under the housing 12. The neck of the reservoir 16 has vertical section a particular shape in 1 with upper shoulders 18 and lower 18 'which engage on either side of the lower wall 14. Springs 19 carried by the lower face of the wall 14 engage the shoulder 18' of the reservoir 16 to ensure good maintenance thereof in the position of use. On the side the box 12 is closed by a door, not visible in the drawing, which can advantageously be locked in order to prohibit access to the tank 16, for the purpose of removing the latter, to any person not authorized.

Dans la paroi avant du boîtier 12 est logé un conduit flexible 20 dont une extrémité 21 débouche vers l'extérieur exactement en regard de l'orifice 10 du conduit principal 9 du couvercle 5, lorsque ce couvercle est en position rabattue. L'autre extrémité du couvercle 20 est disposée à l'intérieur de la chambre 13 et comporte un collier 22 destiné à s'engager sur la tête mobile 17 de façon que l'extrémité de conduit 21 soit maintenue en regard de l'orifice de sortie (non représenté) ménagé dans la tête 17. Un dispositif à ressort (de type connu et qu'on n'a pas représenté pour la clarté du dessin) permet, lorsque la tête 17 a été enfoncée (de la façon qu'on verra plus loin) puis relâchée, de rappeler celle-ci en position haute en un laps de temps prédéterminé.In the front wall of the housing 12 is housed a flexible conduit 20, one end 21 of which opens outwards exactly opposite the orifice 10 of the main conduit 9 of the cover 5, when this cover is in the folded position. The other end of the cover 20 is disposed inside the chamber 13 and comprises a collar 22 intended to engage on the movable head 17 so that the end of the conduit 21 is held facing the orifice of outlet (not shown) formed in the head 17. A spring device (of known type and which has not been shown for clarity of the drawing) makes it possible, when the head 17 has been depressed (in the manner that see later) then released, to recall it in the high position in a predetermined period of time.

A sa partie supérieure le boîtier 12 comporte, dans l'axe du couvercle 5, une ouverture centrale 23 qui communique avec la chambre 13 et à travers laquelle un prolongement arrière 24 du couvercle 5 peut s'engager dans la chambre 13, lors d'un pivotement du couvercle de sa position rabattue à sa position relevée, en engageant la tête mobile 17 et en forçant celle-ci à s'enfoncer verticalement.At its upper part, the housing 12 comprises, in the axis of the cover 5, a central opening 23 which communicates with the chamber 13 and through which a rear extension 24 of the cover 5 can engage in the chamber 13, when pivoting of the cover from its folded position to its raised position, engaging the movable head 17 and forcing it to sink vertically.

Le fonctionnement du dispositif se comprend aisément d'après la description qui précède. Lorsque le couvercle 5 est en position relevée, son prolongement arrière 24 enfonce la tête mobile 17 en provoquant l'éjection de produit à travers le conduit 20. Toutefois, comme l'orifice de sortie 21 de ce conduit se trouve alors obturé par la partie pleine arquée 11 du couvercle 5, le produit n'est pas diffusé dans les conduits 9 et 7 de ce couvercle. Lorsque le couvercle 5 est ensuite rabattu sur la cuvette, la partie 14 de ce couvercle libère la tête 17 qui remonte lentement sous l'action du ressort de rappel. En même temps, l'orifice 10 du conduit 9 vient en regard de l'extrémité 21 du conduit 20 ce qui permet, jusqu'à ce que la tête 17 soit revenue dans sa position haute de repos, la diffusion par les conduits 7 et les têtes 8 de jets de produit désinfectant qui, en raison de la disposition appropriée des têtes 8, atteignent l'intégralité de la surface intérieure de la cuvette 1, de la surface du siège 2 et des faces inférieure et supérieure de la lunette 3. Cette dernière est prévue pour présenter sur toute sa surface un profil incliné, dirigé vers l'intérieur, en facilitant ainsi l'écoulement dans la cuvette 1 d'un excès éventuel de produit désinfectant pulvérisé sur la face supérieure de cette lunette. Le joint d'étanchéité 6, prévu sur la périphérie du couvercle 5, empêche toute diffusion vers l'extérieur du produit de désinfection.The operation of the device is easily understood from the above description. When the cover 5 is in the raised position, its rear extension 24 pushes the movable head 17 causing the product to be ejected through the conduit 20. However, as the outlet orifice 21 of this conduit is then closed by the part full arc 11 of the cover 5, the product is not diffused in the conduits 9 and 7 of this cover. When the cover 5 is then folded down on the bowl, the part 14 of this cover releases the head 17 which rises slowly under the action of the return spring. At the same time, the orifice 10 of the conduit 9 comes opposite the end 21 of the conduit 20 which allows, until the head 17 has returned to its high rest position, the diffusion through the conduits 7 and the heads 8 of jets of disinfectant which, due to the appropriate arrangement of the heads 8, reach the entire inner surface of the bowl 1, the surface of the seat 2 and the lower and upper faces of the bezel 3. The latter is provided to present over its entire surface an inclined profile, directed inward, thereby facilitating the flow in the bowl 1 of any excess disinfectant sprayed on the upper face of this scope. The seal 6, provided on the periphery of the cover 5, prevents any diffusion towards the outside of the disinfection product.

Quelques secondes après avoir rabattu le couvercle 5, la tête 17 est revenue automatiquement en position de repos en coupant l'émission de produit et, comme le désinfectant utilisé est avantageusement à base de produit volatil tel que l'alcool, les appareils sanitaires se trouvent immédiatement secs et peuvent être utilisés sans délai.A few seconds after having closed the cover 5, the head 17 is automatically returned to the rest position by cutting off the emission of product and, as the disinfectant used is advantageously based on volatile product such as alcohol, the sanitary appliances are immediately dry and can be used immediately.

Lorsque le réservoir 16 est vide et qu'on désire le changer, il suffit d'ouvrir la porte latérale du boîtier 12, d'appliquer une poussée ascendante sur le réservoir 16 pour annihiler l'action des ressorts 19 puis de faire coulisser latéralement le col de ce réservoir hors du boîtier 12. On enlève alors le collier 22 qu'on adapte sur la tête mobile d'un réservoir plein à utiliser, puis on procède de façon inverse pour placer un nouveau réservoir en position d'utilisation.When the tank 16 is empty and you want to change it, just open the side door of the housing 12, apply an upward push on the tank 16 to cancel the action of the springs 19 and then slide the sideways neck of this reservoir outside the housing 12. The collar 22 is then removed which is adapted to the movable head of a full reservoir to be used, then the process is carried out in reverse to place a new reservoir in the position of use.

On comprendra que la description ci-dessus n'a été donnée qu'à simple titre d'exemple, sans caractère limitatif, et que des adjonctions ou des modifications constructives pourraient y être apportées sans sortir du cadre de l'invention tel qu'il est défini par les revendications. En particulier, le produit désinfectant utilisé pourrait être de toute composition convenable et comprendre des additifs tels que des matières désodorisantes. On comprendra également que, sans sortir de l'invention, on pourrait prévoir d'injecter, par les canaux et les têtes de pulvérisation ménagés dans le couvercle rabattable, de l'air ou de l'eau (avec éventuellement addition d'un produit de nettoyage) en reliant l'orifice d'entrée du conduit principal 9 du couvercle 5 au système d'alimentation de la chasse d'eau.It will be understood that the above description has been given only by way of example, without limitation, and that additions or constructive modifications could be made without departing from the scope of the invention as it is defined by the claims. In particular, the disinfecting product used could be of any suitable composition and include additives such as deodorant materials. It will also be understood that, without departing from the invention, provision could be made to inject, via the channels and the spray heads formed in the folding lid, air or water (with the possible addition of a product cleaning) by connecting the inlet port of the main duct 9 of the cover 5 to the flushing power system.
