Description

La présente invention se rapporte au domaine des dispositifs permettant le nettoyage d'objets.The present invention relates to the field of devices allowing the cleaning of objects.

ARRIERE PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

Habituellement, un dispositif de nettoyage d'objet comprend :

  • une enceinte de nettoyage agencée pour y placer plusieurs objets à nettoyer ;
  • au moins une première conduite d'alimentation en fluide débouchant dans l'enceinte de nettoyage pour l'alimenter en fluide ;
  • au moins une première conduite d'évacuation de fluide débouchant dans l'enceinte de nettoyage pour évacuer du fluide contenu dans l'enceinte.
Usually, an object cleaning device includes:
  • a cleaning enclosure arranged to place several objects to be cleaned;
  • at least one first fluid supply pipe opening into the cleaning enclosure to supply it with fluid;
  • at least a first fluid evacuation pipe opening into the cleaning enclosure to evacuate fluid contained in the enclosure.

Cette enceinte de nettoyage comprend au moins des premières et deuxième parties d'enceinte et le dispositif de nettoyage étant adapté à adopter sélectivement :

  • une configuration d'ouverture d'enceinte dans laquelle ces première et deuxième parties d'enceinte sont écartées l'une de l'autre pour permettre l'insertion / ou l'extraction des objets hors de l'enceinte ; et
  • une configuration de fermeture d'enceinte dans laquelle la première partie d'enceinte est en appui contre la deuxième partie d'enceinte pour refermer l'enceinte de manière étanche.
This cleaning enclosure comprises at least first and second enclosure parts and the cleaning device being adapted to selectively adopt:
  • an enclosure opening configuration in which these first and second enclosure parts are spaced apart from each other to allow the insertion/or extraction of objects out of the enclosure; And
  • an enclosure closure configuration in which the first enclosure part bears against the second enclosure part to close the enclosure in a watertight manner.

Des objets qui comportent une ou plusieurs zones creuses sont particulièrement difficiles à nettoyer car les zones creuses sont mal accessibles au fluide de nettoyage. Ainsi un objet présentant un bord périphérique définissant une partie tubulaire de l'objet ouverte à l'une des extrémités de l'objet est particulièrement difficile à nettoyer.Objects which have one or more hollow areas are particularly difficult to clean because the hollow areas are poorly accessible to the cleaning fluid. Thus an object having a peripheral edge defining a tubular part of the object open at one of the ends of the object is particularly difficult to clean.

Cet espace d'accueil est tel que ladite zone centrale de la deuxième partie d'enceinte peut s'étendre à l'intérieur de la partie tubulaire dudit objet alors que cette partie tubulaire s'étend tout autour de cette zone centrale, entre cette zone centrale et ladite première partie d'enceinte.This reception space is such that said central zone of the second enclosure part can extend inside the tubular part of said object while this tubular part extends all around this central zone, between this zone central and said first enclosure part.

Une partie tubulaire de l'objet peut avoir une largeur maximale mesurée dans un plan de section transversale de l'objet qui est supérieure à la longueur de la partie tubulaire ou inversement.A tubular portion of the object may have a maximum width measured in a cross-sectional plane of the object that is greater than the length of the tubular portion or vice versa.

Grâce au dispositif selon l'invention, l'espace d'accueil de l'objet est rendu plus compact autour de l'objet puisque la deuxième partie d'enceinte comporte une zone centrale conformée pour pouvoir s'étendre à l'intérieur de la partie tubulaire de l'objet.Thanks to the device according to the invention, the space for receiving the object is made more compact around the object since the second enclosure part comprises a central zone shaped to be able to extend inside the tubular part of the object.

Ainsi, lorsque le dispositif est en configuration de fermeture et que l'objet est placé dans l'enceinte, la partie tubulaire s'étend autour de la zone centrale, entre la zone centrale et la première partie d'enceinte. Le fluide (vapeur et/ou liquide et/ou gaz) est ainsi guidé par la zone centrale vers l'intérieur de la partie tubulaire de l'objet.Thus, when the device is in the closed configuration and the object is placed in the enclosure, the tubular part extends around the central zone, between the central zone and the first enclosure part. The fluid (steam and/or liquid and/or gas) is thus guided by the central zone towards the interior of the tubular part of the object.

On peut ainsi améliorer l'efficacité du nettoyage de l'objet.We can thus improve the efficiency of cleaning the object.

Cette caractéristique permet aussi de minimiser la quantité de fluide devant être injectée dans l'enceinte pour nettoyer l'objet.This characteristic also makes it possible to minimize the quantity of fluid that must be injected into the enclosure to clean the object.

Par ailleurs, comme l'espace entre l'enceinte et la surface interne de l'objet est minimisée, on peut mieux gérer la vitesse du flux de fluide le long de la paroi de l'objet.Furthermore, as the space between the enclosure and the internal surface of the object is minimized, the speed of the fluid flow along the wall of the object can be better managed.

On a ainsi une zone centrale du dispositif de nettoyage qui est adaptée à l'objet à nettoyer.We thus have a central zone of the cleaning device which is adapted to the object to be cleaned.

Cette adaptation du dispositif de nettoyage est favorable à la qualité de ce nettoyage et au rendement du dispositif selon l'invention.This adaptation of the cleaning device is favorable to the quality of this cleaning and to the performance of the device according to the invention.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Le dispositif de nettoyage 1 selon l'invention est spécifiquement adapté à nettoyer un objet 2, comportant un bord périphérique 20 définissant une partie tubulaire 21 de l'objet 2, cette partie tubulaire 21 étant ouverte vers l'extérieur de l'objet, à l'une au moins de ses extrémités 22.The cleaning device 1 according to the invention is specifically adapted to clean an object 2, comprising a peripheral edge 20 defining a tubular part 21 of the object 2, this tubular part 21 being open towards the outside of the object, at at least one of its ends 22.

Cet objet peut être ouvert à ses deux extrémités (dans ce cas l'objet peut être un tube, ou une paille alimentaire), ou il peut être ouvert à une seule de ses extrémités (dans ce cas l'objet est un récipient comportant un fond).This object can be open at both ends (in this case the object can be a tube, or a food straw), or it can be open at only one of its ends (in this case the object is a container comprising a bottom).

Dans les modes de réalisation illustrés sur les figures 1, 2, 4 et 5, l'objet 2 est un récipient 2 dont la paroi est formée d'un fond 23 du récipient et d'un bord périphérique 20 fermé sur lui-même et s'étendant depuis ce fond 23 et tout autour de ce fond 23.In the embodiments illustrated on the figures 1 , 2 , 4 And 5 , the object 2 is a container 2 whose wall is formed of a bottom 23 of the container and a peripheral edge 20 closed on itself and extending from this bottom 23 and all around this bottom 23.

Dans les différents modes de réalisation illustrés aux figures 1 à 5, le dispositif de nettoyage 1 comprend :

  • une enceinte de nettoyage 11 agencée pour y placer ledit objet 2 ;
  • au moins une première conduite d'alimentation 31 en fluide débouchant dans l'enceinte de nettoyage 11 pour l'alimenter en fluide (en l'occurrence, ce fluide est un fluide de nettoyage pouvant être constitué de liquide et/ou de vapeur et pouvant contenir des particules de nettoyage) ;
  • au moins une première conduite d'évacuation de fluide 41 débouchant dans l'enceinte de nettoyage 11 pour évacuer du fluide contenu dans l'enceinte 11 ; et
ladite enceinte de nettoyage 11 comprend au moins des première et deuxième parties d'enceinte 111, 112.In the different embodiments illustrated in figures 1 to 5 , the cleaning device 1 comprises:
  • a cleaning enclosure 11 arranged to place said object 2 there;
  • at least a first fluid supply pipe 31 opening into the cleaning enclosure 11 to supply it with fluid (in this case, this fluid is a cleaning fluid which may consist of liquid and/or vapor and which may contain cleaning particles);
  • at least one first fluid evacuation pipe 41 opening into the cleaning enclosure 11 to evacuate fluid contained in the enclosure 11; And
said cleaning enclosure 11 comprises at least first and second enclosure parts 111, 112.

Le dispositif de nettoyage 1 est adapté à adopter sélectivement :

  • une configuration d'ouverture d'enceinte dans laquelle ces première et deuxième parties d'enceinte 111, 112 sont écartées l'une de l'autre pour permettre une extraction dudit objet hors de l'enceinte 11 ; et
  • une configuration de fermeture d'enceinte dans laquelle la première partie d'enceinte 111 est en appui contre la deuxième partie d'enceinte 112 pour refermer l'enceinte 11 de manière étanche.
The cleaning device 1 is adapted to selectively adopt:
  • an enclosure opening configuration in which these first and second enclosure parts 111, 112 are spaced apart from each other to allow said object to be extracted from the enclosure 11; And
  • an enclosure closure configuration in which the first enclosure part 111 rests against the second enclosure part 112 to close the enclosure 11 in a watertight manner.

Le dispositif de nettoyage selon l'invention est essentiellement caractérisé en ce qu'il comporte au moins une zone centrale 1120 de ladite la deuxième partie d'enceinte 112 qui, lorsque le dispositif de nettoyage 1 est dans la configuration de fermeture, s'étend à l'intérieur de la première partie d'enceinte 111 (le long d'une face intérieure de cette première partie d'enceinte 111) pour définir, entre la première partie d'enceinte 111 et la zone centrale 1120 de la deuxième partie d'enceinte 112, un espace d'accueil 110 dudit objet 2 s'étendant tout autour de cette zone centrale 1120.The cleaning device according to the invention is essentially characterized in that it comprises at least one central zone 1120 of said second enclosure part 112 which, when the cleaning device 1 is in the closed configuration, extends inside the first enclosure part 111 (along an interior face of this first enclosure part 111) to define, between the first enclosure part 111 and the central zone 1120 of the second part d enclosure 112, a reception space 110 of said object 2 extending all around this central zone 1120.

Cet espace d'accueil 110 dudit objet 2 est tel que ladite zone centrale 1120 de la deuxième partie d'enceinte 112 peut s'étendre à l'intérieur de la partie tubulaire 21 dudit objet 2 alors que cette partie tubulaire 21 s'étend tout autour de cette zone centrale 1120, entre cette zone centrale 1120 et ladite première partie d'enceinte 111. Les conduites 31, 41 sont disposées pour déboucher vers ledit espace d'accueil 110 de l'objet 2.This reception space 110 of said object 2 is such that said central zone 1120 of the second enclosure part 112 can extend inside the tubular part 21 of said object 2 while this tubular part 21 extends all the way. around this central zone 1120, between this central zone 1120 and said first enclosure part 111. The pipes 31, 41 are arranged to open towards said reception space 110 of the object 2.

En d'autres termes, lorsque le dispositif est en configuration de fermeture, la zone centrale 1120 de la deuxième partie d'enceinte 112 s'étend à l'intérieur de ladite première partie d'enceinte 111 tout en étant à distance de cette première partie d'enceinte 111 pour créer un espace d'accueil 110 dudit objet 2.In other words, when the device is in the closed configuration, the central zone 1120 of the second enclosure part 112 extends inside said first enclosure part 111 while being at a distance from this first enclosure part 111 to create a reception space 110 of said object 2.

Cet espace d'accueil 110 s'étend tout autour de la zone centrale 1120 de la deuxième partie d'enceinte 112. Ainsi, l'objet 2 peut être placé entre la première partie d'enceinte 111 et la zone centrale 1120, cette zone centrale 1120 s'étendant alors dans la partie tubulaire 21 de l'objet 2 tout en créant, tout autour de l'objet, un passage de circulation de fluide entre l'objet et l'enceinte.This reception space 110 extends all around the central zone 1120 of the second enclosure part 112. Thus, the object 2 can be placed between the first enclosure part 111 and the central zone 1120, this zone central 1120 then extending into the tubular part 21 of the object 2 while creating, all around the object, a fluid circulation passage between the object and the enclosure.

Comme expliqué précédemment, le dispositif 1 selon l'invention permet d'avoir une enceinte de nettoyage 11 particulièrement compacte car elle est formée pour accueillir un seul objet 2 avec une zone centrale 1120 de la deuxième partie d'enceinte 112 qui pénètre dans cet objet 2.As explained previously, the device 1 according to the invention makes it possible to have a particularly compact cleaning enclosure 11 because it is formed to accommodate a single object 2 with a central zone 1120 of the second enclosure part 112 which penetrates this object 2.

On réduit ainsi le volume entre l'enceinte et l'objet, ce qui permet de diminuer la quantité de fluide de nettoyage nécessaire au nettoyage.This reduces the volume between the enclosure and the object, which makes it possible to reduce the quantity of cleaning fluid necessary for cleaning.

Le coût et la durée du nettoyage de l'objet peuvent ainsi être minimisés.The cost and time of cleaning the object can thus be minimized.

Préférentiellement, lorsque le dispositif 1 est en configuration de fermeture, la zone centrale 1120 de la deuxième partie d'enceinte 112 pénètre à l'intérieur de la première partie d'enceinte sur au moins 30%, préférentiellement au moins 50%, préférentiellement au moins 80% de la profondeur de cette première partie d'enceinte 111.Preferably, when the device 1 is in the closed configuration, the central zone 1120 of the second enclosure part 112 penetrates inside the first enclosure part over at least 30%, preferably at least 50%, preferably at less 80% of the depth of this first part of enclosure 111.

Cette zone centrale 1120 est une forme de révolution autour d'un axe de symétrie de la zone centrale. En l'occurrence, cette zone centrale 1120 est ici en forme de dôme.This central zone 1120 is a form of revolution around an axis of symmetry of the central zone. In this case, this central zone 1120 is here in the shape of a dome.

Comme on le voit sur les figures 1 et 2, la première partie d'enceinte 111 présente un bord périphérique 1111 et ladite deuxième partie d'enceinte présente un bord périphérique 1121.As seen on the figures 1 And 2 , the first enclosure part 111 has a peripheral edge 1111 and said second enclosure part has a peripheral edge 1121.

Ces bords périphériques 1111, 1121 des première et deuxième parties d'enceinte 111, 112 sont agencés pour venir en appui l'un contre et pour définir une étanchéité périphérique entre ces première et deuxième parties d'enceinte 111, 112 lorsque le dispositif de nettoyage 1 est dans sa configuration de fermeture.These peripheral edges 1111, 1121 of the first and second enclosure parts 111, 112 are arranged to come to bear against one another and to define a peripheral seal between these first and second enclosure parts 111, 112 when the cleaning device 1 is in its closed configuration.

La zone centrale 1120 de la deuxième partie d'enceinte 112 est à distance du bord périphérique 1121 de ladite deuxième partie d'enceinte.The central zone 1120 of the second enclosure part 112 is at a distance from the peripheral edge 1121 of said second enclosure part.

Préférentiellement, ladite première conduite d'alimentation en fluide 31 est formée dans une paroi de ladite première partie d'enceinte 111.Preferably, said first fluid supply pipe 31 is formed in a wall of said first enclosure part 111.

Cette première conduite d'alimentation en fluide 31 étant en communication avec ledit espace d'accueil 110 de l'objet via au moins une perforation d'alimentation 311, 312, 313 formée au travers de cette paroi de ladite première partie d'enceinte 111.This first fluid supply pipe 31 being in communication with said reception space 110 of the object via at least one supply perforation 311, 312, 313 formed through this wall of said first enclosure part 111 .

Le dispositif 1 comprend aussi une deuxième conduite d'alimentation en fluide 32 débouchant dans l'enceinte de nettoyage 11 pour l'alimenter en fluide.The device 1 also comprises a second fluid supply pipe 32 opening into the cleaning enclosure 11 to supply it with fluid.

Cette deuxième conduite 32 est formée dans une paroi de ladite deuxième partie d'enceinte 112 et elle est en communication avec ledit espace d'accueil 110 de l'objet 2 via au moins une perforation d'alimentation 321 formée au travers de cette paroi de ladite deuxième partie d'enceinte 112.This second pipe 32 is formed in a wall of said second enclosure part 112 and it is in communication with said reception space 110 of the object 2 via at least one supply perforation 321 formed through this wall of said second enclosure part 112.

Préférentiellement, comme illustré sur les figures 4 et 5, le dispositif 1 comporte aussi une troisième conduite d'alimentation en fluide 33 qui débouche dans l'enceinte de nettoyage 11 au niveau d'une zone d'accueil 110b d'une extrémité de la partie tubulaire du bord périphérique 20 de l'objet.Preferably, as illustrated in the figures 4 And 5 , the device 1 also comprises a third fluid supply pipe 33 which opens into the cleaning enclosure 11 at a reception zone 110b of one end of the tubular part of the peripheral edge 20 of the object .

Cette troisième conduite 33 permet d'injecter du fluide de nettoyage au niveau d'une extrémité terminale de la partie tubulaire de l'objet 2, ce qui améliore le nettoyage de cette zone.This third pipe 33 makes it possible to inject cleaning fluid at a terminal end of the tubular part of the object 2, which improves the cleaning of this area.

Dans le cas où l'objet 2 à nettoyer est un verre, le fluide injecté via cette troisième conduite 33 est orienté vers la lèvre du verre (la lèvre est l'une des zones les plus contaminées et difficile à nettoyer du verre).In the case where the object 2 to be cleaned is a glass, the fluid injected via this third pipe 33 is directed towards the lip of the glass (the lip is one of the most contaminated and difficult to clean areas of the glass).

Cette troisième conduite 33 débouche dans l'espace 110 au niveau d'une perforation 331.This third pipe 33 opens into space 110 at a perforation 331.

L'alimentation en fluide vers l'enceinte se fait :

  • via au moins une perforation d'alimentation, en l'occurrence via trois perforations 311, 312, 313, formées au travers de la paroi de ladite première partie 111 d'enceinte 11 qui est au-dessus de la deuxième partie d'enceinte 112 ; et
  • via au moins une perforation d'alimentation 321 formée au travers de la paroi de ladite deuxième partie d'enceinte 112 qui est sous la première partie d'enceinte 111 ; et éventuellement
  • via d'autres perforations reliées à d'autres conduites d'alimentation en fluide comme la troisième conduite 33. La première conduite d'alimentation 31 est disposée pour déboucher en vis-à-vis d'une surface externe 221 de l'objet et la deuxième conduite d'alimentation 32 est disposée pour déboucher en vis-à-vis d'une surface interne 220 de l'objet.
The fluid supply to the enclosure is done:
  • via at least one feed perforation, in this case via three perforations 311, 312, 313, formed through the wall of said first part 111 of enclosure 11 which is above the second part of enclosure 112 ; And
  • via at least one feed perforation 321 formed through the wall of said second enclosure part 112 which is under the first enclosure part 111; and eventually
  • via other perforations connected to other fluid supply pipes such as the third pipe 33. The first supply pipe 31 is arranged to open facing an external surface 221 of the object and the second supply pipe 32 is arranged to open facing an internal surface 220 of the object.

La première partie d'enceinte 111 présente un évidement principal délimitant l'espace d'accueil 110, cet évidement est délimité par une surface de révolution s'étendant autour d'un axe de symétrie principal de cette première partie d'enceinte 111.The first enclosure part 111 has a main recess delimiting the reception space 110, this recess is delimited by a surface of revolution extending around a main axis of symmetry of this first enclosure part 111.

La première conduite d'alimentation 31 s'étend dans la paroi de la première partie d'enceinte 111 et la première perforation 311 débouche au niveau de l'espace d'accueil 110 au fond de l'évidement principal.The first supply pipe 31 extends in the wall of the first enclosure part 111 and the first perforation 311 opens at the level of the reception space 110 at the bottom of the main recess.

Cette première conduite 31 a une forme d'arc s'étendant le long de l'évidement principal et les seconde et troisième perforations 312 et 313 qui relient cette première conduite 31 à l'espace d'accueil 110 sont formées sur des côtés opposés de l'évidement principal de la première partie d'enceinte 111, en l'occurrence au niveau des extrémités terminales de la forme d'arc de la première conduite 31.This first pipe 31 has an arc shape extending along the main recess and the second and third perforations 312 and 313 which connect this first pipe 31 to the reception space 110 are formed on opposite sides of the main recess of the first enclosure part 111, in this case at the level of the terminal ends of the arc shape of the first pipe 31.

Préférentiellement, certaines au moins des perforations 311, 312, 313, 321 sont orientées suivant un axe de sortie de fluide qui forme vis-à-vis d'une ligne tangente à l'enceinte à l'endroit de la perforation, un angle d'alimentation en fluide qui est inférieur à 45°, préférentiellement égal à 25° à plus ou moins 15°, par rapport à la surface de l'espace d'accueil où est réalisée la perforation d'alimentation.Preferably, at least some of the perforations 311, 312, 313, 321 are oriented along an axis of fluid outlet which forms, with respect to a line tangent to the enclosure at the location of the perforation, a fluid supply angle which is less than 45°, preferably equal to 25° more or less 15°, relative to the surface of the reception space where the supply perforation is made.

L'effet de cet angle d'alimentation est d'avoir une arrivée de fluide qui est tangentielle par rapport à l'objet à nettoyer.The effect of this supply angle is to have a fluid inlet which is tangential to the object to be cleaned.

On favorise ainsi un écoulement homogène de flux de fluide sur toute la surface à nettoyer.This promotes a homogeneous flow of fluid over the entire surface to be cleaned.

Comme illustré aux figures 3, 4 et 5, le dispositif 1 peut aussi comporter une unité de commande 6 du dispositif 1.As illustrated in figures 3 , 4 And 5 , the device 1 can also include a control unit 6 of the device 1.

Cette unité de commande 6 est reliée à une première électrovanne V1 pour commander un changement d'état de cette première électrovanne V1 entre un premier état dans lequel cette première électrovanne autorise le passage de fluide vers l'enceinte via la première conduite d'alimentation 31 et un second état dans lequel cette première électrovanne V1 interdit le passage de fluide vers l'enceinte 11 via la première conduite d'alimentation 31.This control unit 6 is connected to a first solenoid valve V1 to control a change of state of this first solenoid valve V1 between a first state in which this first solenoid valve authorizes the passage of fluid towards the enclosure via the first supply line 31 and a second state in which this first solenoid valve V1 prohibits the passage of fluid towards the enclosure 11 via the first supply pipe 31.

Dans le mode de réalisation de la figure 3, cette première électrovanne V1 est reliée à la fois à la première conduite 31 et à la deuxième conduite 32 de manière à ce que :

  • lorsque cette première électrovanne V1 se trouve dans son premier état, elle autorise le passage de fluide vers l'enceinte via les première et deuxième conduites d'alimentation 31, 32 ; et que
  • lorsque cette première électrovanne V1 se trouve dans son second état, elle interdise le passage de fluide vers l'enceinte via les première et deuxième conduites d'alimentation 31, 32.
In the embodiment of the Figure 3 , this first solenoid valve V1 is connected both to the first pipe 31 and to the second pipe 32 so that:
  • when this first solenoid valve V1 is in its first state, it authorizes the passage of fluid towards the enclosure via the first and second supply lines 31, 32; and
  • when this first solenoid valve V1 is in its second state, it prevents the passage of fluid towards the enclosure via the first and second supply lines 31, 32.

Au contraire, dans le mode de réalisation des figures 4 et 5, le dispositif comporte une deuxième électrovanne V2 reliée à ladite unité de commande 6 pour commander un changement d'état de cette deuxième électrovanne V2 entre :

  • un premier état dans lequel cette deuxième électrovanne V2 autorise le passage de fluide vers l'enceinte 11 via la deuxième conduite d'alimentation 32 ; et
  • un second état dans lequel cette deuxième électrovanne V2 interdit le passage de fluide vers l'enceinte 11 via la deuxième conduite d'alimentation V2.
On the contrary, in the embodiment of the figures 4 And 5 , the device comprises a second solenoid valve V2 connected to said control unit 6 to control a change of state of this second solenoid valve V2 between:
  • a first state in which this second solenoid valve V2 authorizes the passage of fluid towards the enclosure 11 via the second supply line 32; And
  • a second state in which this second solenoid valve V2 prohibits the passage of fluid towards the enclosure 11 via the second supply line V2.

Comme on le comprend des modes représentés aux figures 4 et 5, la première électrovanne V1 permet une obturation sélective de ladite au moins une première conduite d'alimentation 31, et la deuxième électrovanne V2 permet une obturation sélective de ladite au moins une deuxième conduite d'alimentation 32.As we understand from the modes represented in figures 4 And 5 , the first solenoid valve V1 allows selective closing of said at least one first supply line 31, and the second solenoid valve V2 allows selective closing of said at least one second supply line 32.

Comme les première et deuxième conduites d'alimentation 31, 32 débouchent dans l'enceinte 11 à des endroits éloignés, on peut ainsi choisir l'endroit d'injection de fluide dans l'enceinte en fonction de la forme de l'objet à nettoyer et/ou du cycle de nettoyage impliquant successivement une alimentation via la première conduite 31 et une alimentation via la deuxième conduite 32.As the first and second supply pipes 31, 32 open into the enclosure 11 at distant locations, it is thus possible to choose the location of fluid injection into the enclosure depending on the shape of the object to be cleaned. and/or the cleaning cycle successively involving a supply via the first pipe 31 and a supply via the second pipe 32.

Selon l'invention, et en fonction de la forme et de la taille de l'enceinte 11 qui est adaptée à recevoir l'objet à nettoyer, on peut avoir plus de deux conduites d'alimentation, équipées ou pas d'électrovannes commandées par l'unité de commande.According to the invention, and depending on the shape and size of the enclosure 11 which is adapted to receive the object to be cleaned, we can have more than two supply lines, equipped or not with solenoid valves controlled by the control unit.

Ainsi, conformément aux modes de réalisation des figures 4 et 5, l'unité de commande est également reliée à une troisième électrovanne V3 pour commander un changement d'état de cette troisième électrovanne V3 entre un premier état dans lequel cette troisième électrovanne autorise le passage de fluide vers l'enceinte via la troisième conduite d'alimentation 33 et un second état dans lequel cette troisième électrovanne V3 interdit le passage de fluide vers l'enceinte via la troisième conduite d'alimentation 33.Thus, in accordance with the embodiments of the figures 4 And 5 , the control unit is also connected to a third solenoid valve V3 to control a change of state of this third solenoid valve V3 between a first state in which this third solenoid valve authorizes the passage of fluid towards the enclosure via the third supply line 33 and a second state in which this third solenoid valve V3 prohibits the passage of fluid towards the enclosure via the third supply line 33.

Dans le mode de réalisation illustré à la figure 5, on a une quatrième conduite d'alimentation en fluide 34 qui débouche dans l'espace d'accueil 110 via au moins une perforation 341 formée dans la paroi de la deuxième partie d'enceinte 112.In the embodiment illustrated in figure 5 , we have a fourth fluid supply pipe 34 which opens into the reception space 110 via at least one perforation 341 formed in the wall of the second enclosure part 112.

Cette perforation 341 est placée à distance des autres perforations 311, 321, 331 qui relient les autres conduites à l'enceinte 11.This perforation 341 is placed at a distance from the other perforations 311, 321, 331 which connect the other pipes to the enclosure 11.

Cette quatrième conduite 34 permet une admission supplémentaire de fluide dans l'enceinte ce qui est particulièrement utile lorsque la taille de l'enceinte est importante. Cette enceinte 11 de la figure 5 est ici adaptée à recevoir un récipient tel une carafe ou une gourde qui est de plus grande taille que le verre à boisson de la figure 4.This fourth pipe 34 allows additional admission of fluid into the enclosure which is particularly useful when the size of the enclosure is large. This enclosure 11 of the Figure 5 is here adapted to receive a container such as a carafe or a flask which is larger in size than the drink glass of the figure 4 .

Comme illustré aux figures 1 à 5, le dispositif peut aussi comporter une première conduite d'admission d'air 71 vers l'enceinte 11 qui débouche dans cette enceinte de nettoyage 11 pour y admettre de l'air.As illustrated in figures 1 to 5 , the device can also include a first air intake pipe 71 towards the enclosure 11 which opens into this cleaning enclosure 11 to admit air there.

Cette première conduite d'admission d'air 71 est équipée d'un moyen de fermeture 8 de la première conduite d'admission d'air (par exemple un clapet antiretour 8 ou une électrovanne commandée par l'unité de commande 6) adapté à autoriser le passage d'air vers l'enceinte et à interdire la sortie de fluide hors de l'enceinte via cette conduite d'admission d'air 71. Le moyen de fermeture 8 est préférentiellement placé au plus près de l'enceinte, en l'occurrence à moins de 1 cm de l'enceinte, préférentiellement à moins de 2 mm de l'enceinte.This first air intake pipe 71 is equipped with a means of closing 8 of the first air intake pipe (for example a non-return valve 8 or a solenoid valve controlled by the control unit 6) adapted to authorize the passage of air towards the enclosure and prevent the exit of fluid from the enclosure via this air intake pipe 71. The closing means 8 is preferably placed as close as possible to the enclosure, in the occurrence less than 1 cm from the enclosure, preferably less than 2 mm from the enclosure.

L'admission d'air 71 est utile pour sécher l'objet nettoyé et en évacuer le fluide de nettoyage résiduel et pour le refroidir. Le refroidissement se produit par l'évacuation de calories par l'air circulant le long de l'objet et par effet d'évaporation. La chaleur latente de vaporisation induit une perte de chaleur du récipient. Idéalement, l'air admis à une température préférentiellement comprise entre 10°C et 70°C, préférentiellement entre 10°C et 50°C, idéalement égale à la température ambiante autour du dispositif à plus ou moins 5°C.The air inlet 71 is useful for drying the cleaned object and discharging residual cleaning fluid therefrom and for cooling it. Cooling occurs by the evacuation of calories by the air circulating along the object and by the evaporation effect. The latent heat of vaporization induces heat loss from the container. Ideally, the air admitted at a temperature preferably between 10°C and 70°C, preferably between 10°C and 50°C, ideally equal to the ambient temperature around the device at plus or minus 5°C.

Grâce à ce mode de réalisation, dès que la pression dans l'enceinte 11 augmente, par exemple parce que l'on y injecte du fluide tel que du liquide ou de la vapeur via la première et/ou la deuxième et/ou la troisième conduite d'alimentation 31, 32, 33, ce clapet antiretour 8 obture la conduite d'admission d'air 71.Thanks to this embodiment, as soon as the pressure in the enclosure 11 increases, for example because fluid such as liquid or vapor is injected there via the first and/or the second and/or the third supply line 31, 32, 33, this non-return valve 8 closes the air intake line 71.

Par contre, ce clapet 8 laisse passer l'air via la première conduite d'admission d'air 71 dès que la pression dans la conduite d'admission d'air 71 est supérieure, d'au moins une valeur d'écart de pression prédéterminée, par rapport à la pression dans l'enceinte 11.On the other hand, this valve 8 lets the air pass via the first air intake pipe 71 as soon as the pressure in the air intake pipe 71 is higher, by at least one pressure difference value. predetermined, relative to the pressure in enclosure 11.

Alternativement, à cette solution avec clapet antiretour 8, il est possible que cette conduite 71 soit équipée d'une électrovanne d'admission d'air 8 reliée à ladite unité de commande 6 pour commander un changement d'état de cette électrovanne d'admission d'air entre :

  • un premier état dans lequel cette électrovanne d'admission d'air autorise le passage d'air via la première conduite d'admission d'air 71 ; et
  • un second état dans lequel cette électrovanne d'admission d'air 8 interdit le passage d'air via cette conduite d'admission d'air 71.
Alternatively, to this solution with non-return valve 8, it is possible that this pipe 71 is equipped with an air intake solenoid valve 8 connected to said control unit 6 to control a change of state of this intake solenoid valve air enters:
  • a first state in which this air intake solenoid valve allows the passage of air via the first air intake pipe 71; And
  • a second state in which this air intake solenoid valve 8 prohibits the passage of air via this air intake pipe 71.

Dans ce mode de réalisation illustré aux figures 3, 4 et 5, lors de l'injection de fluide via l'une au moins des conduites d'alimentation 31, 32, 33, l'électrovanne d'admission d'air 8 est actionnée dans son second état pour interdire le passage de fluide via la conduite d'admission d'air.In this embodiment illustrated in figures 3 , 4 And 5 , during the injection of fluid via at least one of the supply lines 31, 32, 33, the air intake solenoid valve 8 is actuated in its second state to prevent the passage of fluid via the line air intake.

Par contre, après avoir réalisé cette injection de fluide de nettoyage, on cherche à sécher l'objet et l'électrovanne d'admission d'air 8 est alors actionnée pour autoriser le passage d'air via la conduite d'admission d'air 71.On the other hand, after having carried out this injection of cleaning fluid, we seek to dry the object and the air intake solenoid valve 8 is then actuated to allow the passage of air via the air intake pipe. 71.

Le dispositif 1 comporte également un corps de chauffe 9 adapté à chauffer un liquide.The device 1 also includes a heating body 9 adapted to heat a liquid.

Dans un mode particulier, le corps de chauffe 9 est adapté à générer de la vapeur à partir de ce liquide.In a particular mode, the heating body 9 is adapted to generate steam from this liquid.

Ce corps de chauffe 9 est fluidiquement relié à l'ensemble des conduites d'alimentation en fluide 31, 32, 33 pour pouvoir alimenter l'enceinte de nettoyage 11 en fluide chauffé par le corps de chauffe 9.This heating body 9 is fluidly connected to all of the fluid supply pipes 31, 32, 33 to be able to supply the cleaning enclosure 11 with fluid heated by the heating body 9.

Le dispositif comporte aussi une cuve de stockage 10 dudit liquide fluidiquement reliée audit corps de chauffe 9 pour l'alimenter en liquide.The device also includes a storage tank 10 for said liquid fluidly connected to said heating body 9 to supply it with liquid.

Ce dispositif 1 comporte également une pompe 100 pour forcer l'admission dudit liquide vers ledit corps de chauffe 9.This device 1 also includes a pump 100 to force the admission of said liquid to said heating body 9.

Idéalement, la pompe 100 et le corps de chauffe 9 sont également reliés à ladite unité de commande 6 qui peut commander d'une part la chauffe du corps de chauffe 9 et d'autre part le pompage de liquide par la pompe 100 selon un cycle déterminé.Ideally, the pump 100 and the heating body 9 are also connected to said control unit 6 which can control on the one hand the heating of the heating body 9 and on the other hand the pumping of liquid by the pump 100 according to a cycle determined.

Dans un mode particulier, la cuve de stockage 10 et la pompe 100 pourraient être remplacées par une liaison à un réseau d'adduction en liquide potable externe au dispositif 1.In a particular mode, the storage tank 10 and the pump 100 could be replaced by a connection to a drinking liquid supply network external to the device 1.

Dans les modes des figures 1 à 5, on constate que première conduite d'admission d'air 71 passe au travers de la deuxième partie d'enceinte 112 et débouche dans l'enceinte 11 au niveau de cette deuxième partie d'enceinte 112. Ceci est intéressant pour faciliter le séchage de la surface interne 220 de l'objet 2. Préférentiellement, comme illustré sur ces mêmes modes de réalisations des figures 1 à 5, ce dispositif comporte une deuxième conduite d'admission d'air 710 qui passe au travers de la première partie d'enceinte 111 et débouche dans l'enceinte 11 au niveau de cette première partie d'enceinte 111.In the fashions of figures 1 to 5 , we see that first air intake pipe 71 passes through the second enclosure part 112 and opens into the enclosure 11 at this second enclosure part 112. This is interesting for facilitating the drying of the internal surface 220 of the object 2. Preferably, as illustrated in these same embodiments of the figures 1 to 5 , this device comprises a second air intake pipe 710 which passes through the first enclosure part 111 and opens into the enclosure 11 at this first enclosure part 111.

Ceci est intéressant pour faciliter le séchage de la surface externe 220 de l'objet 2.This is useful for facilitating the drying of the external surface 220 of object 2.

De la même manière que pour ladite première conduite d'admission d'air 71, cette deuxième conduite d'admission d'air 710 peut être équipée d'un clapet antiretour 80 adapté à autoriser le passage d'air vers l'enceinte 11 et à interdire la sortie de fluide hors de l'enceinte 11 via cette deuxième conduite 710.In the same way as for said first air intake pipe 71, this second air intake pipe 710 can be equipped with a non-return valve 80 adapted to allow the passage of air towards the enclosure 11 and to prevent the exit of fluid from enclosure 11 via this second pipe 710.

Alternativement, de la même manière que pour ladite première conduite d'admission d'air 71, cette deuxième conduite d'admission d'air 710 peut être équipée d'une électrovanne 80 reliée à l'unité de commande 6 pour autoriser sélectivement le passage d'air vers l'espace d'accueil 110 de l'objet.Alternatively, in the same way as for said first air intake pipe 71, this second air intake pipe 710 can be equipped with a solenoid valve 80 connected to the control unit 6 to selectively authorize the passage of air towards the reception space 110 of the object.

Préférentiellement, le dispositif comporte une turbine de circulation d'air 72 reliée fluidiquement à la première conduite d'admission d'air 71 et/ou à la deuxième conduite d'admission d'air 710 et/ou à la première conduite d'évacuation de fluide 41 pour pouvoir forcer un écoulement d'air au travers de l'enceinte tout autour de l'objet 2.Preferably, the device comprises an air circulation turbine 72 fluidly connected to the first air intake pipe 71 and/or to the second air intake pipe 710 and/or to the first evacuation pipe of fluid 41 to be able to force a flow of air through the enclosure all around the object 2.

Ce mode de réalisation permet d'accélérer le séchage et le refroidissement de l'objet 2.This embodiment makes it possible to accelerate the drying and cooling of object 2.

En reliant cette turbine 72 à la conduite d'évacuation 41 on peut, avec une seule turbine, forcer la circulation d'air des conduites d'admission 71, 710 vers l'enceinte de manière à avoir des flux d'air passe le long des surfaces interne 220 et externe 221 de l'objet puis se dirige vers la conduite d'évacuation 41. Le séchage est ainsi particulièrement efficace.By connecting this turbine 72 to the evacuation pipe 41 it is possible, with a single turbine, to force the circulation of air from the intake pipes 71, 710 towards the enclosure so as to have air flows pass along of the internal 220 and external 221 surfaces of the object then moves towards the evacuation pipe 41. Drying is thus particularly effective.

Idéalement, cette turbine 72 est préférentiellement reliée à l'unité de commande 6 pour sélectivement mettre en circulation de l'air dans ladite enceinte 11 en fonction d'un cycle de nettoyage.Ideally, this turbine 72 is preferentially connected to the control unit 6 to selectively circulate air in said enclosure 11 as a function of a cleaning cycle.

Préférentiellement, la première conduite d'évacuation de fluide 41 est formée dans une paroi de ladite deuxième partie d'enceinte 112, cette première conduite d'évacuation de fluide 41 étant en communication avec ledit espace d'accueil 110 de l'objet via au moins une perforation d'évacuation formée au travers de cette paroi de ladite deuxième partie d'enceinte 112.Preferably, the first fluid discharge pipe 41 is formed in a wall of said second enclosure part 112, this first fluid discharge pipe 41 being in communication with said reception space 110 of the object via at minus one evacuation perforation formed through this wall of said second enclosure part 112.

Ainsi, l'évacuation de fluide hors de l'enceinte 11 se fait via une perforation d'évacuation formée au travers de cette paroi de ladite deuxième partie d'enceinte 112 (la deuxième partie d'enceinte 112 est préférentiellement sous la première partie d'enceinte 111 ce qui facilite l'écoulement gravitaire du fluide hors de l'enceinte 11). Cette perforation d'évacuation 41 formée au travers de la paroi de ladite deuxième partie d'enceinte 112 est préférentiellement annulaire et formée en vis-à-vis d'une portion dudit espace d'accueil 110 qui est adaptée à recevoir le bord périphérique 20 de l'objet.Thus, the evacuation of fluid from the enclosure 11 is done via an evacuation perforation formed through this wall of said second enclosure part 112 (the second enclosure part 112 is preferably under the first part d enclosure 111 which facilitates the gravity flow of the fluid out of enclosure 11). This evacuation perforation 41 formed through the wall of said second enclosure part 112 is preferably annular and formed opposite a portion of said reception space 110 which is adapted to receive the peripheral edge 20 of the object.

Ainsi, l'air et les fluides ont tendance à être évacués en face du bord périphérique 20 de l'objet.Thus, air and fluids tend to be evacuated opposite the peripheral edge 20 of the object.

On peut faire en sorte que des butées 410 de support de l'objet 2 s'étendent en travers de cette perforation d'évacuation qui est destinée à recevoir la partie tubulaire 21 de l'objet. Ces butées 410 permettent de supporter / caler l'objet lorsqu'il est inséré dans l'espace d'accueil de l'objet 110.It can be ensured that stops 410 supporting the object 2 extend across this evacuation perforation which is intended to receive the tubular part 21 of the object. These stops 410 make it possible to support / support the object when it is inserted in the reception space of the object 110.

Préférentiellement, comme illustré sur les figures 1, 2, 4 et 5, la deuxième partie d'enceinte 112 est formée par une pièce inférieure présentant une portion centrale et une portion en forme une couronne qui est périphérique de la portion centrale. Les butées de support 410 forment des rayons reliant la portion centrale à la portion en forme une couronne.Preferably, as illustrated in the figures 1 , 2 , 4 And 5 , the second enclosure part 112 is formed by a lower part having a central portion and a crown-shaped portion which is peripheral to the central portion. The support stops 410 form spokes connecting the central portion to the crown-shaped portion.

La première conduite d'admission d'air 71 qui passe au travers de la deuxième partie d'enceinte 112 peut cheminer successivement au travers de la portion en forme de couronne, de l'un de ces rayons et de la portion centrale où elle débouche dans l'espace d'accueil de l'objet.The first air intake pipe 71 which passes through the second enclosure part 112 can pass successively through the crown-shaped portion, one of these rays and the central portion where it opens in the object's home space.

Comme on le voit sur les modes de réalisation illustrés aux figures 4 et 5, le dispositif selon l'invention peut aussi comporter des moyens de mise en rotation 200 de l'objet 2.As seen in the embodiments illustrated in figures 4 And 5 , the device according to the invention can also include means for rotating object 2 200.

Ces moyens de mise en rotation 200 sont agencés pour exercer sur ledit objet 20 se trouvant dans ledit espace d'accueil 110 de l'objet un effort tangentiel tendant à entraîner l'objet en rotation vis-à-vis de ladite enceinte de nettoyage 11.These rotation means 200 are arranged to exert on said object 20 located in said object receiving space 110 a tangential force tending to cause the object to rotate with respect to said cleaning enclosure 11 .

La mise en rotation 200 permet d'uniformiser le nettoyage et le séchage.Rotation 200 makes cleaning and drying uniform.

Les moyens de mise en rotation 200 peuvent être mis en œuvre de différentes manières.The rotation means 200 can be implemented in different ways.

Dans le mode de réalisation des figures 4 et 5, ces moyens 200 comprennent une pluralité de galets d'entrainement 201 placés dans l'enceinte 11 et au moins un moteur d'entrainement 202 de l'un au moins de ces galets d'entrainement 201.In the embodiment of figures 4 And 5 , these means 200 comprise a plurality of drive rollers 201 placed in the enclosure 11 and at least one drive motor 202 of at least one of these drive rollers 201.

La liaison entre galet d'entrainement 201 et moteur 202 est préférentiellement réalisée via des tiges 203 de mise en rotation passant au travers de la paroi d'une des parties de l'enceinte 11.The connection between drive roller 201 and motor 202 is preferably made via adjustment rods 203 in rotation passing through the wall of one of the parts of the enclosure 11.

Chaque tige donnée 203 passe par une perforation de la paroi de l'enceinte 11 qui lui correspond et elle est montée à rotation par rapport à cette perforation selon un axe de symétrie de cette tige donnée 203, un joint d'étanchéité s'étendant contre la tige pour s'opposer au passage de fluide le long de cette tige donnée. Alternativement au galet ou en complément de ces galets, les moyens de mise en rotation 200 peuvent comprendre des buses d'injection de fluide à l'intérieur de l'enceinte orientées tangentiellement par rapport à une surface interne de l'enceinte.Each given rod 203 passes through a perforation in the wall of the enclosure 11 which corresponds to it and it is mounted to rotate relative to this perforation along an axis of symmetry of this given rod 203, a seal extending against the rod to oppose the passage of fluid along this given rod. Alternatively to the roller or in addition to these rollers, the rotation means 200 may comprise fluid injection nozzles inside the enclosure oriented tangentially relative to an internal surface of the enclosure.

Ainsi, le fluide injecté tangentiellement à la surface interne de l'enceinte exerce un effort tangentiel sur le récipient ce qui permet de le mettre en rotation.Thus, the fluid injected tangentially to the internal surface of the enclosure exerts a tangential force on the container which allows it to rotate.

Ce fluide peut être du liquide et/ou de la vapeur lors du nettoyage du récipient ou de l'air lors du séchage du récipient.This fluid may be liquid and/or vapor when cleaning the container or air when drying the container.

Ainsi, certaines au moins des conduites d'alimentation en fluide 31, 32 et/ou certaines au moins des conduites d'admission d'air 71, 710 peuvent être équipées de telles buses d'injection de fluide orientées tangentiellement par rapport à une surface interne de l'enceinte.Thus, at least some of the fluid supply pipes 31, 32 and/or at least some of the air intake pipes 71, 710 can be equipped with such fluid injection nozzles oriented tangentially relative to a surface. internal of the enclosure.

Il est également possible que le dispositif 1 comprenne des buses de nettoyage de l'intérieur de l'enceinte qui sont uniquement destinées à être utilisées lorsque l'enceinte est libérée de l'objet 2.It is also possible that the device 1 includes nozzles for cleaning the interior of the enclosure which are only intended to be used when the enclosure is released from the object 2.

Ces buses de nettoyage sont utilisables pour nettoyer l'enceinte après avoir enlevé l'objet de l'enceinte.These cleaning nozzles can be used to clean the enclosure after removing the object from the enclosure.

De telles buses de nettoyage débouchent à différents endroits de l'enceinte et certaines peuvent être en regard de parties de l'enceinte qui sont masquées lorsque l'objet est inséré dans l'enceinte.Such cleaning nozzles open out at different locations in the enclosure and some may face parts of the enclosure which are hidden when the object is inserted into the enclosure.

Dans un mode particulier de réalisation du dispositif selon l'invention, l'une au moins des première et deuxième parties d'enceinte 111, 112 peut être déformable entre une forme compactée dans laquelle le volume de l'espace d'accueil 110 de l'objet 2 est maximum et une forme expansée dans laquelle le volume de l'espace d'accueil 110 de l'objet 2 est minimum.In a particular embodiment of the device according to the invention, at least one of the first and second enclosure parts 111, 112 can be deformable between a compacted shape in which the volume of the reception space 110 of the object 2 is maximum and an expanded form in which the volume of the reception space 110 of object 2 is minimum.

Dans ce mode de réalisation, on peut changer la forme de la première partie d'enceinte 111 et/ou de la deuxième partie d'enceinte 112.In this embodiment, the shape of the first enclosure part 111 and/or the second enclosure part 112 can be changed.

La partie d'enceinte déformable est ainsi approchée de l'objet lorsqu'elle est dans sa forme dite expansée et elle est éloignée de l'objet lorsqu'elle est dans sa forme dite compactée.The deformable enclosure part is thus brought closer to the object when it is in its so-called expanded form and it is moved away from the object when it is in its so-called compacted form.

On a ainsi une capacité d'ajustement de forme qui peut être utile pour adapter l'enceinte à la forme de l'objet. Ainsi, on peut chercher à augmenter l'espace d'accueil de l'objet pour faciliter le retrait de l'objet hors de l'enceinte et, au contraire, on peut chercher à réduire cet espace pour minimiser le volume de fluide devant circuler entre l'enceinte et l'objet à nettoyer.We thus have a shape adjustment capacity which can be useful for adapting the enclosure to the shape of the object. Thus, we can seek to increase the reception space of the object to facilitate the removal of the object from the enclosure and, on the contrary, we can seek to reduce this space to minimize the volume of fluid having to circulate between the enclosure and the object to be cleaned.

Cette variation de forme peut aussi être intéressante pour adapter la forme de l'enceinte à la forme de l'objet à nettoyer.This variation in shape can also be useful for adapting the shape of the enclosure to the shape of the object to be cleaned.

Ceci est particulièrement intéressant pour pouvoir nettoyer des objets de différentes tailles et/ou différentes formes avec un même dispositif de nettoyage 1.This is particularly interesting for being able to clean objects of different sizes and/or different shapes with the same cleaning device 1.

Pour être déformable, la partie d'enceinte déformable peut comprendre une membrane élastiquement déformable :

  • sous l'effet d'un fluide sous pression injecté contre une zone de la membrane pour commander son déplacement en direction de l'objet (la zone de membrane soumise à la pression du fluide peut être un passage de fluide interne à la membrane ou une face de la membrane soumise à la pression de ce fluide) ; et/ou
  • sous l'effet d'un mécanisme de poussée de la membrane adapté à déplacer cette membrane en direction de l'objet. Ladite au moins une partie d'enceinte, déformable ou non, peut aussi comporter des bossages 5 disposés vers l'espace d'accueil 110 de l'objet 2.
To be deformable, the deformable enclosure part may comprise an elastically deformable membrane:
  • under the effect of a pressurized fluid injected against a zone of the membrane to control its movement in the direction of the object (the membrane zone subjected to the pressure of the fluid can be a fluid passage internal to the membrane or a face of the membrane subjected to the pressure of this fluid); and or
  • under the effect of a membrane pushing mechanism adapted to move this membrane in the direction of the object. Said at least one enclosure part, deformable or not, can also include bosses 5 arranged towards the reception space 110 of the object 2.

Ces bossages 5 sont destinés à venir en appui contre l'objet lorsque celui-ci est placé dans l'enceinte et que cette au moins une partie d'enceinte dans sa forme expansée tout en définissant un passage de fluide autour de ces bossages, entre l'objet et cette au moins une partie d'enceinte déformable.These bosses 5 are intended to come to bear against the object when it is placed in the enclosure and that this at least one part of the enclosure in its expanded form while defining a passage of fluid around these bosses, between the object and this at least one part of deformable enclosure.

Comme on le voit sur l'exemple illustré à la figure 3, le dispositif 1 comporte une cuve de stockage 10 du liquide de nettoyage reliée fluidiquement à l'entrée du corps de chauffe 9 via une conduite qui passe successivement par :

  • un filtre anticalcaire 102 ;
  • une pompe 100 pour forcer l'admission dudit liquide vers ledit corps de chauffe 9 ; et
  • une vanne deux voies 104 commandée par l'unité de commande 6.
As seen in the example illustrated in Figure 3 , the device 1 comprises a storage tank 10 for the cleaning liquid fluidly connected to the inlet of the heating body 9 via a pipe which passes successively through:
  • an anti-limescale filter 102;
  • a pump 100 for forcing the admission of said liquid to said heating body 9; And
  • a two-way valve 104 controlled by the control unit 6.

Cette vanne deux voie est mobile entre une configuration ouverte dans laquelle elle obture la conduite reliant la pompe 100 au corps de pompe 9 et une configuration fermée dans laquelle elle autorise le passage de liquide via cette conduite.This two-way valve is movable between an open configuration in which it closes the pipe connecting the pump 100 to the pump body 9 and a closed configuration in which it allows the passage of liquid via this pipe.

Une sonde de température 106 est disposée pour mesurer la température du fluide en sortie du corps de chauffe, cette sonde est reliée à l'unité de commande 6.A temperature probe 106 is arranged to measure the temperature of the fluid leaving the heating body, this probe is connected to the control unit 6.

Ainsi, l'unité de commande 6 peut, en prenant en compte une mesure de température réalisée avec cette sonde 106, réguler la chauffe du fluide par le corps de chauffe afin d'atteindre une température cible du fluide de nettoyage. En sortie, le corps de chauffe 9 est relié à une première voie d'une électrovanne trois voies 107 commandée par l'unité de commande 6.Thus, the control unit 6 can, by taking into account a temperature measurement carried out with this probe 106, regulate the heating of the fluid by the heating body in order to reach a target temperature of the cleaning fluid. At the output, the heating body 9 is connected to a first channel of a three-way solenoid valve 107 controlled by the control unit 6.

Un réservoir d'effluents 112 est d'une part relié à une seconde voie de cette électrovanne 107 et à la première conduite d'évacuation de fluide 41.An effluent tank 112 is on the one hand connected to a second channel of this solenoid valve 107 and to the first fluid evacuation pipe 41.

Ainsi, le réservoir d'effluent 112 permet de recueillir des effluents provenant de l'enceinte 11 et des effluents provenant du corps de chauffe 9.Thus, the effluent tank 112 makes it possible to collect effluents coming from the enclosure 11 and effluents coming from the heating body 9.

Les première et seconde voies de l'électrovanne 107 sont par exemple mis en communication lorsque l'on souhaite nettoyer le corps de chauffe 9.The first and second channels of the solenoid valve 107 are for example put into communication when it is desired to clean the heating body 9.

Cette électrovanne 107 comporte également une troisième voie qui est reliée à une entrée d'un réservoir 108 qui permet de stocker un volume de fluide chauffé que l'on souhaite injecter dans l'enceinte.This solenoid valve 107 also includes a third way which is connected to an inlet of a reservoir 108 which makes it possible to store a volume of heated fluid which it is desired to inject into the enclosure.

La sortie du réservoir 108 est reliée aux première et deuxième conduites d'alimentation en fluide 31 et 32 qui débouchent dans l'enceinte 11 via ladite première électrovanne deux voies V1.The outlet of the reservoir 108 is connected to the first and second fluid supply pipes 31 and 32 which open into the enclosure 11 via said first two-way solenoid valve V1.

Le volume de ce réservoir 108 est prévu pour accumuler et stocker du fluide chauffé par le corps de chauffe 9, par exemple du liquide et/ou de la vapeur, puis pour le délivrer vers l'enceinte 111.The volume of this reservoir 108 is designed to accumulate and store fluid heated by the heating body 9, for example liquid and/or steam, then to deliver it to the enclosure 111.

Ce réservoir 108 permet d'avoir un stock tampon de fluide chauffé placé entre le corps de chauffe et l'enceinte 11. Ceci peut être avantageux pour bénéficier d'une puissance instantanée de chauffe supérieure à celle pouvant être générée instantanément par le corps de chauffe.This reservoir 108 makes it possible to have a buffer stock of heated fluid placed between the heating body and the enclosure 11. This can be advantageous for benefiting from an instantaneous heating power greater than that which can be generated instantly by the heating body .

Ceci permet aussi de chauffer du fluide à l'aide du corps de chauffe 9 tout en le maintenant isolé de l'enceinte 11.This also makes it possible to heat the fluid using the heating body 9 while keeping it isolated from the enclosure 11.

Il est aussi possible que le dispositif 1 ne comporte pas de réservoir 108. Dans ce cas, la troisième voie de l'électrovanne trois voies 107 n'est pas reliée à l'entrée du réservoir 108 mais elle est directement reliée à l'une au moins de conduites 31 et 32, la première vanne V1 étant alors constituée par cette électrovanne 107.It is also possible that the device 1 does not include a reservoir 108. In this case, the third channel of the three-way solenoid valve 107 is not connected to the inlet of the tank 108 but it is directly connected to at least one of pipes 31 and 32, the first valve V1 then being constituted by this solenoid valve 107.

Enfin, comme indiqué précédemment, l'invention concerne aussi un ensemble comprenant :

  • un objet 2 comportant un bord périphérique 20 définissant une partie tubulaire 21 qui est ouverte à l'une au moins de ses extrémités 22, cette partie tubulaire présentant une surface interne 220 ; et
  • un dispositif de nettoyage 1 selon l'un quelconque des modes de réalisation précités pris seul ou en combinaison, ce dispositif étant placé dans sa configuration de fermeture d'enceinte.
Finally, as indicated previously, the invention also relates to an assembly comprising:
  • an object 2 comprising a peripheral edge 20 defining a tubular part 21 which is open at at least one of its ends 22, this tubular part having an internal surface 220; And
  • a cleaning device 1 according to any one of the aforementioned embodiments taken alone or in combination, this device being placed in its enclosure closing configuration.

L'objet est disposé à l'intérieur dudit espace d'accueil de manière à ce que plus de 90% de sa surface interne 220 soit placée à une distance de ladite zone centrale 1120 de la deuxième partie d'enceinte 112 qui est comprise entre 0.1% et 10% d'une dimension maximale externe dudit objet 2.The object is arranged inside said reception space so that more than 90% of its internal surface 220 is placed at a distance from said central zone 1120 of the second enclosure part 112 which is between 0.1% and 10% of a maximum external dimension of said object 2.

Avec plus de 90% de la surface interne 220 de la partie tubulaire placée à une distance de la zone centrale 1120 de l'enceinte qui est comprise entre 0.1% et 10% d'une dimension maximale dudit objet, on génère un volume de circulation de fluide le long de la paroi interne 220 de l'objet 2 qui est limité. On limite ainsi la consommation de fluide lors du nettoyage et on obtient une section de passage de fluide réduite entre l'enceinte et la paroi de l'objet.With more than 90% of the internal surface 220 of the tubular part placed at a distance from the central zone 1120 of the enclosure which is between 0.1% and 10% of a maximum dimension of said object, a circulation volume is generated of fluid along the internal wall 220 of the object 2 which is limited. We thus limit the consumption of fluid during cleaning and we obtain a reduced fluid passage section between the enclosure and the wall of the object.

Ceci permet d'augmenter la vitesse du fluide le long de la paroi de l'objet à nettoyer.This increases the speed of the fluid along the wall of the object to be cleaned.

En limitant le volume de fluide devant circuler dans l'enceinte, on réduit la consommation de fluide et d'énergie nécessaire pour le nettoyage de l'objet.By limiting the volume of fluid that must circulate in the enclosure, the consumption of fluid and energy necessary for cleaning the object is reduced.

En effet, plus ce volume de fluide est faible et plus le besoin d'énergie pour circuler et chauffer ce fluide est réduit. On augmente ainsi le rendement énergétique du dispositif selon l'invention.In fact, the lower this volume of fluid, the lower the energy requirement to circulate and heat this fluid. This increases the energy efficiency of the device according to the invention.

De manière similaire, la première partie d'enceinte est telle que lorsque l'objet est placé dans l'enceinte et que le dispositif est dans sa configuration de fermeture, alors plus de 90% de sa surface externe 221 de l'objet 2 est placée à une distance de la première partie d'enceinte 111 qui est comprise entre 0.1% et 10% de la dimension maximale externe dudit objet 2.Similarly, the first enclosure part is such that when the object is placed in the enclosure and the device is in its closed configuration, then more than 90% of its external surface 221 of the object 2 is placed at a distance from the first enclosure part 111 which is between 0.1% and 10% of the maximum external dimension of said object 2.

Ainsi, pour un objet ayant une dimension maximal externe de 10cm (cette dimension peut être la longueur de l'objet ou son envergure), plus de 90% de la toute la surface de la paroi de l'objet est placée entre 0.1 mm et 1 cm, préférentiellement 0.5 mm, vis-à-vis de l'enceinte du dispositif de nettoyage en configuration de fermeture d'enceinte.Thus, for an object having a maximum external dimension of 10cm (this dimension can be the length of the object or its wingspan), more than 90% of the entire surface of the wall of the object is placed between 0.1 mm and 1 cm, preferably 0.5 mm, with respect to the enclosure of the cleaning device in enclosure closing configuration.

Grâce à l'invention, on fait en sorte que l'espace d'accueil 110 de l'objet présente une forme proche de la forme de l'objet. Ceci permet d'optimiser le flux de fluide de nettoyage pour améliorer le nettoyage.Thanks to the invention, we ensure that the reception space 110 of the object has a shape close to the shape of the object. This optimizes the flow of cleaning fluid to improve cleaning.
