Description

B.0679 ext APPAREIL DE STERILISATION DE BIBERONSB.0679 ext APPARATUS FOR STERILIZING BOTTLES
La présente invention concerne un appareil de stérilisation de biberons et de leurs accessoires, telles les tétines, les bagues de serrage, les capuchons, etc..The present invention relates to a device for sterilizing baby bottles and their accessories, such as teats, clamping rings, caps, etc.
Les appareils de stérilisation de biberons sont constitués d'un récipient fermé par un couvercle à l'intérieur duquel sont disposés les biberons et leurs accessoires. Une cuve contenant de l'eau est placée en partie inférieure du récipient, l'eau étant transformée en vapeur par, un élément chauffant électrique placé en contact thermique avec la cuve. La vapeur générée par l'ébullition de l'eau dans la cuve circule à l'intérieur du récipient et réalise la stérilisation des objets placés dans le récipient.Bottle sterilization devices consist of a container closed by a lid inside which the bottles and their accessories are arranged. A tank containing water is placed in the lower part of the container, the water being transformed into vapor by an electric heating element placed in thermal contact with the tank. The steam generated by boiling water in the tank circulates inside the container and sterilizes the objects placed in the container.
Un tel appareil est décrit dans le document EP 0 718 000 au nom de la demanderesse où plusieurs biberons sont placés sur un support reposant à l'intérieur du récipient, les tétines étant placées sur un panier perforé placé au- dessus du support de biberons. Le fond du récipient est équipé d'une plaque chauffante, pilotée par un thermostat, formant cuve et contenant de l'eau qui est portée à l'ébullition lors de l'alimentation en énergie électrique de l'élément chauffant de la cuve. En fonctionnement, une certaine quantité d'eau est versée au fond de la cuve et l'appareil est mis en route. Le cycle de stérilisation est terminé lorsque toute l'eau est évaporée, l'alimentation de la plaque chauffante étant alors coupée par le thermostat. Fonctionnant à satisfaction, cet appareil nécessite toutefois un temps de stérilisation important, car pour stériliser un ou tous les biberons placés dans le récipient le cycle complet de stérilisation dure environ 12 min.Such an apparatus is described in document EP 0 718 000 in the name of the applicant where several bottles are placed on a support resting inside the container, the teats being placed on a perforated basket placed above the support for bottles. The bottom of the container is equipped with a heating plate, controlled by a thermostat, forming a tank and containing water which is brought to the boil during the supply of electrical energy to the heating element of the tank. In operation, a certain amount of water is poured into the bottom of the tank and the device is started up. The sterilization cycle is complete when all the water has evaporated, the supply to the heating plate being cut off by the thermostat. Operating satisfactorily, this device however requires a long sterilization time, because to sterilize one or all the bottles placed in the container the complete sterilization cycle lasts about 12 min.
Par ailleurs, le document EP 0 209 409 décrit un appareil électrique apte à réaliser le réchauffage et la stérilisation d'un biberon, comportant une cuve de réchauffage munie d'un élément chauffant contrôlé par un thermostat adapté au réchauffage des biberons. Le thermostat est shunté par un interrupteur placé dans le circuit électrique de l'appareil et permet d'élever la température de fonctionnement de l'élément chauffant lorsque l'appareil est en mode stérilisation. Un tel appareil permet donc de chauffer rapidement l'eau contenue dans sa cuve chauffante et de stériliser ainsi un seul biberon placé dans ladite cuve fermée alors d'un couvercle. Toutefois, cet appareil présente l'inconvénient de stériliser uniquement un seul biberon à la fois, la durée de stérilisation de plusieurs biberons étant alors multipliée par leur nombre auquel on rajoute des temps intermédiaires de préparation de l'appareil et des biberons à stériliser.Furthermore, document EP 0 209 409 describes an electrical device capable of heating and sterilizing a baby bottle, comprising a heating tank provided with a heating element controlled by a thermostat suitable for heating baby bottles. The thermostat is bypassed by a switch placed in the electrical circuit of the device and allows to raise the temperature operating mode of the heating element when the device is in sterilization mode. Such an apparatus therefore makes it possible to quickly heat the water contained in its heating tank and thus to sterilize a single bottle placed in said tank then closed with a lid. However, this device has the drawback of sterilizing only one bottle at a time, the sterilization time of several bottles being then multiplied by their number to which are added intermediate times for preparing the device and bottles to be sterilized.
On connaît également du document GB 2 306 328 un autoclave à deux chambres de stérilisation disposées l'une au dessus de l'autre dans un casier monté sur des roulettes. L'inconvénient de cet appareil est que chaque chambre de stérilisation doit comporter son propre générateur de vapeur muni de ses propres moyens de contrôle, ce qui complique la construction et surtout augmente le coût de réalisation d'un tel appareil.Document GB 2 306 328 also discloses an autoclave with two sterilization chambers arranged one above the other in a rack mounted on casters. The disadvantage of this device is that each sterilization chamber must have its own steam generator provided with its own control means, which complicates the construction and above all increases the cost of producing such a device.
Un autre document, le GB 272 284 décrit, lui, un appareil destiné à stériliser des récipients utilisés dans une ferme. L'appareil comporte une chaudière à pétrole qui fait vaporiser l'eau d'un réservoir pour l'envoyer ensuite par un réseau de conduits de vapeur dans les compartiments de stérilisation de l'appareil. On remarque plus particulièrement dans ce document le réseau complexe de conduits de vapeur, munis chacun d'un robinet, d'une buse de sortie et éventuellement d'une soupape de non retour, qui rendent la construction de l'appareil particulièrement encombrante et complexe. Une telle solution ne convient pas à un stérilisateur de biberons, généralement de construction beaucoup plus compacte.Another document, GB 272 284, describes an apparatus intended to sterilize containers used on a farm. The device includes an oil boiler which evaporates water from a tank and then sends it through a network of steam pipes in the sterilization compartments of the device. We note more particularly in this document the complex network of steam conduits, each provided with a tap, an outlet nozzle and possibly a non-return valve, which make the construction of the device particularly bulky and complex. . Such a solution is not suitable for a baby bottle sterilizer, generally of much more compact construction.
Le but de l'invention est de remédier au moins en partie à ces inconvénients et de proposer un appareil de stérilisation de biberons apte à réaliser la stérilisation soit d'un biberon individuel, soit de plusieurs biberons en même temps, pour un temps optimum de stérilisation adapté au nombre de biberons à stériliser. Un autre but de l'invention est un appareil de stérilisation de biberons apte à réaliser une stérilisation rapide d'un ou plusieurs biberons, qui soit de construction simplifiée et compacte, tout en étant fiable en fonctionnement.The object of the invention is to remedy these drawbacks at least in part and to provide a bottle sterilization device capable of carrying out the sterilization either of an individual bottle or of several bottles at the same time, for an optimum time of sterilization adapted to the number of bottles to be sterilized. Another object of the invention is a bottle sterilization device capable of carrying out rapid sterilization of one or more bottles, which is of simplified and compact construction, while being reliable in operation.
Un autre but de l'invention est un appareil de stérilisation de biberons apte à assurer le maintien et le transport en conditions hygiéniques d'au moins un biberon stérilisé par l'appareil.Another object of the invention is a bottle sterilization device capable of ensuring the maintenance and transport in hygienic conditions of at least one bottle sterilized by the device.
Ces buts sont atteints avec un appareil de stérilisation de biberons comprenant une cuve comportant une cavité de production de vapeur et un couvercle qui prend appui sur la cuve et forme avec cette dernière une enceinte apte à recevoir un ou des biberons à stériliser, du fait que ladite enceinte est séparée de ladite cavité de production de vapeur par une paroi munie d'orifices communicants, et que l'appareil comporte des moyens de séparation et de commutation qui sont aptes à délimiter à l'intérieur de ladite enceinte un compartiment et à mettre sélectivement en communication ladite enceinte ou ledit compartiment avec ledit moyen de production de vapeur de l'appareil directement à travers les orifices de la paroi.These goals are achieved with a bottle sterilization device comprising a tank comprising a steam production cavity and a cover which bears on the tank and forms with the latter an enclosure capable of receiving one or more bottles to be sterilized, because said enclosure is separated from said steam producing cavity by a wall provided with communicating orifices, and that the apparatus includes separation and switching means which are capable of delimiting inside said enclosure a compartment and putting selectively in communication with said enclosure or said compartment with said device for producing steam from the device directly through the orifices in the wall.
Cet appareil est donc conçu de manière à pouvoir séparer l'enceinte localisée à l'intérieur de la cuve en deux chambres, une petite chambre correspondant au compartiment, ayant par conséquent des dimensions réduites comparé à l'ensemble de l'enceinte, et une plus grande chambre correspondant à l'espace résiduel de l'enceinte. Un moyen commun de production de vapeur est avantageusement prévu pour envoyer la vapeur dans l'une ou l'autre des chambres directement (c'est-à-dire sans tuyauterie ou autre moyen de transport à distance interposés entre l'endroit de production de vapeur et l'enceinte) à travers les orifices d'une paroi intermédiaire située entre l'enceinte et le moyen de production de vapeur.This device is therefore designed so as to be able to separate the enclosure located inside the tank into two chambers, a small chamber corresponding to the compartment, consequently having reduced dimensions compared to the whole of the enclosure, and a larger room corresponding to the remaining space of the enclosure. A common means of steam production is advantageously provided for sending steam into one or other of the chambers directly (that is to say without piping or other means of remote transport interposed between the place of production of steam and the enclosure) through the orifices of an intermediate wall situated between the enclosure and the means for producing steam.
Selon l'invention, l'appareil comporte des moyens de séparation prévus pour délimiter un compartiment de dimensions réduites à l'intérieur de l'enceinte. L'appareil comporte, de plus, des moyens de commutation prévus pour envoyer la vapeur soit uniquement dans le compartiment délimité à l'intérieur de l'enceinte, soit dans toute l'enceinte. Les moyens de commutation et de séparation peuvent être des moyens distincts, l'enceinte pouvant alors comporter, par exemple, une paroi verticale délimitant un compartiment dans une enceinte verticale et une paroi de fond horizontale comportant une ouverture communiquant avec ledit compartiment et une autre communiquant avec le reste de l'enceinte, ouvertures qui sont obturées par un tiroir lorsqu'il est actionné par l'utilisateur. Dans un autre mode de réalisation de l'invention, la séparation du compartiment dans l'enceinte et la commutation du flux de vapeur entre le compartiment et l'enceinte se font par des moyens uniques, par exemple une paroi verticale mobile munie d'un jeu d'orifices latéraux communiquant avec ceux en vis-à-vis de l'enceinte et apte en même temps (par exemple en actionnant des obturateurs ou des volets) à commuter les ouvertures de la paroi intermédiaire agencée entre la cavité de production de vapeur et l'enceinte.According to the invention, the device comprises separation means provided for delimiting a compartment of reduced dimensions inside the enclosure. The apparatus further comprises switching means provided for sending steam either only in the compartment delimited inside the enclosure, or in the whole enclosure. The switching and separation means can be separate means, the enclosure then being able to comprise, for example, a vertical wall delimiting a compartment in a vertical enclosure and a horizontal bottom wall comprising an opening communicating with said compartment and another communicating with the rest of the enclosure, openings which are closed by a drawer when actuated by the user. In another embodiment of the invention, the separation of the compartment in the enclosure and the switching of the vapor flow between the compartment and the enclosure are done by unique means, for example a movable vertical wall provided with a set of lateral orifices communicating with those opposite the enclosure and capable at the same time (for example by actuating shutters or shutters) of switching the openings of the intermediate wall arranged between the steam production cavity and the enclosure.
Ainsi, la vapeur produite dans la cuve peut alors être dirigée, par exemple par un système de volets, obturateurs, tiroirs, etc., soit dans ce compartiment de plus petites dimensions, soit dans l'ensemble de l'enceinte, y compris- dans le compartiment. Selon le mode de fonctionnement choisi, on peut alors stériliser soit uniquement les objets placés dans le compartiment de plus petites dimensions, soit l'ensemble des objets placés dans l'enceinte, la quantité d'eau utilisée et/ou le temps de fonctionnement étant adaptés au type de fonctionnement choisi.Thus, the vapor produced in the tank can then be directed, for example by a system of shutters, shutters, drawers, etc., either in this compartment of smaller dimensions, or in the whole of the enclosure, including- in the compartment. Depending on the operating mode chosen, it is then possible to sterilize either only the objects placed in the compartment of smaller dimensions, or all of the objects placed in the enclosure, the amount of water used and / or the operating time being adapted to the type of operation chosen.
Selon une réalisation avantageuse de l'invention, on peut placer un seul biberon dans le compartiment. On rajoute alors dans la cuve une quantité d'eau moindre, ce qui fait que l'appareil monte plus rapidement en température et que le cycle de stérilisation est fortement réduit. Dans une variante on peut adapter le temps de stérilisation au volume de l'enceinte ou à celui du compartiment. Un système de volets met alors le volume du compartiment en relation avec celui de la cuve, sans perte dans l'enceinte.According to an advantageous embodiment of the invention, a single bottle can be placed in the compartment. A smaller amount of water is then added to the tank, which means that the device rises more quickly in temperature and that the sterilization cycle is greatly reduced. In a variant, the sterilization time can be adapted to the volume of the enclosure or to that of the compartment. A shutter system then puts the volume of the compartment in relation to that of the tank, without loss in the enclosure.
Dans le cas où toute l'enceinte, c'est à dire la grande chambre et la petite chambre constituée par le compartiment contiennent chacune des biberons à stériliser, la vapeur produite par la cuve chauffante de l'appareil est alors dirigée dans l'ensemble de l'enceinte.In the case where the whole enclosure, i.e. the large room and the small chamber constituted by the compartment each contain bottles to sterilize, the steam produced by the heating tank of the device is then directed throughout the enclosure.
On obtient ainsi une stérilisation rapide d'un seul biberon, tout en ayant la possibilité de stériliser plusieurs biberons avec un même appareil.A rapid sterilization of a single bottle is thus obtained, while having the possibility of sterilizing several bottles with the same device.
Avantageusement, ledit compartiment est tubulaire et est apte à contenir un biberon.Advantageously, said compartment is tubular and is capable of containing a bottle.
Un tel compartiment tubulaire peut alors délimiter dans l'ensemble de l'enceinte un volume suffisant pour stériliser un seul biberon. La zone périphérique comprise entre la base de ce tube et celle de l'enceinte est alors obturée, la vapeur produite par la cuve étant uniquement dirigée à l'intérieur de ce compartiment tubulaire, sans perte dans l'ensemble de l'enceinte. Des tests effectués en laboratoire ont montré que l'on arrive ainsi à réduire un cycle de stérilisation de 40 % pour la stérilisation d'un seul biberon, par rapport à un cycle complet de stérilisation d'un ensemble de six biberons avec l'appareil de l'invention.Such a tubular compartment can then delimit in the entire enclosure a volume sufficient to sterilize a single bottle. The peripheral zone between the base of this tube and that of the enclosure is then closed, the vapor produced by the tank being directed only inside this tubular compartment, without loss throughout the enclosure. Laboratory tests have shown that we can reduce a sterilization cycle by 40% for the sterilization of a single bottle, compared to a complete sterilization cycle of a set of six bottles with the device. of the invention.
Utilement, ledit compartiment est fermé et sa paroi de fond comporte au moins un orifice inférieur de passage de la vapeur en provenance de la cuve.Usefully, said compartment is closed and its bottom wall has at least one lower orifice for the passage of steam from the tank.
Ainsi, ce compartiment délimite un espace fermé à l'intérieur duquel est effectuée la stérilisation d'un seul biberon, la vapeur arrivant par un orifice inférieur qui le met en communication avec la cuve de l'appareil.Thus, this compartment delimits a closed space inside which is carried out the sterilization of a single bottle, the steam arriving by a lower orifice which puts it in communication with the tank of the device.
De préférence, ladite cuve est un cylindre ou une portion de cylindre et ledit compartiment est agencé au centre de rotation du cylindre ou de la portion de cylindre.Preferably, said tank is a cylinder or a cylinder portion and said compartment is arranged at the center of rotation of the cylinder or of the cylinder portion.
Ceci permet d'obtenir, pour un volume constant de la cuve, une construction compacte de cette dernière, pour un rangement optimisé des biberons autour d'un compartiment central, lorsque la cuve est un cylindre. Dans une autre réalisation de l'appareil de l'invention, la cuve est une portion de cylindre et le compartiment central est agencé au centre de rotation de ladite portion de cylindre en étant proche de la paroi latérale de la cuve, ce qui permet d'agencer les autres biberons sur la périphérie cylindrique de la cuve pour obtenir également un rangement optimisé de tous les biberons dans l'enceinte.This allows to obtain, for a constant volume of the tank, a compact construction of the latter, for an optimized storage of the bottles around a central compartment, when the tank is a cylinder. In another embodiment of the apparatus of the invention, the tank is a portion of cylinder and the central compartment is arranged at the center of rotation of said portion of cylinder by being close to the side wall of the tank, which allows d '' arrange the other bottles on the cylindrical periphery of the tank to also obtain an optimized storage of all the bottles in the enclosure.
Avantageusement, ladite cuve comporte une première paroi ajourée sensiblement horizontale agencée à distance de sa paroi de fond et comportant au moins un orifice central et un ou plusieurs orifices périphériques.Advantageously, said tank comprises a first substantially horizontal perforated wall arranged at a distance from its bottom wall and comprising at least one central orifice and one or more peripheral orifices.
De préférence, ladite cuve comporte une deuxième paroi ajourée agencée contre la première paroi ajourée et comportant au moins un orifice central et un ou plusieurs orifices périphériques.Preferably, said tank comprises a second perforated wall arranged against the first perforated wall and comprising at least one central orifice and one or more peripheral orifices.
De telles parois ajourées forment alors support pour le ou les biberons placés dans l'enceinte, au-dessus de la cuve, permettant à l'eau de s'égoutter et de retomber dans la cuve à travers leurs orifices respectifs. Ces parois peuvent être, suivant la forme de la cuve, des disques ou des portions de disques. Lorsqu'il s'agit d'une paroi en forme de portion de disque, par orifices centraux, on comprend les orifices placés au centre ou autour du centre de rotation de la portion de disque.Such perforated walls then form a support for the bottle or bottles placed in the enclosure, above the tank, allowing the water to drip and fall back into the tank through their respective orifices. These walls may be, depending on the shape of the tank, discs or portions of discs. In the case of a wall in the form of a disc portion, by central orifices, one understands the orifices placed at the center or around the center of rotation of the disc portion.
Avantageusement, l'une des parois ajourées est montée fixe par rapport à la cuve et l'autre paroi ajourée est mobile entre une première position, dite de circulation complète, où leurs orifices centraux et périphériques se font face et une deuxième position, dite de circulation restreinte, où l'une des parois obture les orifices périphériques de l'autre paroi.Advantageously, one of the perforated walls is mounted fixed relative to the tank and the other perforated wall is movable between a first position, called complete circulation, where their central and peripheral orifices face each other and a second position, called restricted circulation, where one of the walls blocks the peripheral orifices of the other wall.
Ainsi, de par sa mobilité, l'une des parois peut alors obturer les orifices de l'autre paroi, formant ainsi un système d'obturation de construction simplifiée permettant à la vapeur en provenance de la cuve chauffante de l'appareil d'être dirigée au centre ou au centre et sur la périphérie desdites parois. Utilement, lesdites parois ajourées sont mobiles en rotation l'une par rapport à l'autre.Thus, by virtue of its mobility, one of the walls can then close the orifices of the other wall, thus forming a shutter system of simplified construction allowing the steam coming from the heating tank of the appliance to be directed at the center or at the center and on the periphery of said walls. Usefully, said perforated walls are movable in rotation relative to one another.
Ainsi, on arrive à obtenir un déplacement relatif d'une paroi par rapport à l'autre en utilisant un faible déplacement angulaire de l'une des parois.Thus, we manage to obtain a relative displacement of one wall relative to the other by using a small angular displacement of one of the walls.
De préférence, ledit compartiment est solidaire de la paroi ajourée mobile. Ceci permet au compartiment d'effectuer le même mouvement que la paroi mobile, en même temps que cette dernière.Preferably, said compartment is integral with the movable perforated wall. This allows the compartment to perform the same movement as the movable wall, at the same time as the latter.
De préférence, ledit compartiment présente une poignée faisant saillie à l'extérieur de l'appareil.Preferably, said compartment has a handle projecting from the outside of the device.
Cette poignée, permet alors d'actionner le compartiment depuis l'extérieur de l'appareil et de lui imprimer, ainsi qu'à la paroi ajourée mobile le mouvement de rotation nécessaire à la mise en correspondance ou à l'obturation de certains orifices des parois ajourées.This handle then makes it possible to actuate the compartment from outside the device and to print to it, as well as to the movable perforated wall, the rotational movement necessary for matching or closing certain orifices of the openwork walls.
Selon l'invention, le compartiment est monté amovible par rapport à la cuve.According to the invention, the compartment is removably mounted relative to the tank.
De par son amovibilité, ce compartiment peut alors être retiré de la cuve, avec l'avantage de pouvoir transporter avec ce compartiment un biberon et ses accessoires stérilisés, sans les toucher, les préservant ainsi du contact avec les germes, bactéries, etc. Par ailleurs, un tel compartiment amovible agit comme une clé que l'on peut utiliser pour actionner en rotation la paroi ajourée mobile.By virtue of its removable nature, this compartment can then be removed from the tank, with the advantage of being able to transport with this compartment a bottle and its sterilized accessories, without touching them, thus preserving them from contact with germs, bacteria, etc. Furthermore, such a removable compartment acts as a key which can be used to actuate the movable perforated wall in rotation.
De préférence, le compartiment est fermé par un couvercle muni d'une poignée. Le couvercle permet de garder étanche l'intérieur du compartiment et en même temps de pouvoir accéder à l'intérieur de ce dernier. La poignée de ce couvercle sert alors de moyen de préhension du compartiment.Preferably, the compartment is closed by a cover provided with a handle. The cover keeps the interior of the compartment watertight and at the same time allows access to the interior of the latter. The handle of this cover then serves as a means of gripping the compartment.
Avantageusement, le compartiment comporte un support en sa partie supérieure. Ceci permet d'agencer le corps du biberon en partie inférieure du compartiment et ses accessoires (tétine, bague, capuchon), en partie supérieure du compartiment, sur ledit support.Advantageously, the compartment has a support in its upper part. This allows the body of the bottle to be arranged in the lower part of the compartment and its accessories (teat, ring, cap), in the upper part of the compartment, on said support.
Utilement, ledit compartiment est cylindrique. Ceci permet de mieux conformer l'espace intérieur du compartiment à la forme extérieure du biberon à stériliser. Le volume d'un tel compartiment est alors mieux adapté à la stérilisation d'un seul biberon.Usefully, said compartment is cylindrical. This allows the interior space of the compartment to better conform to the exterior shape of the bottle to be sterilized. The volume of such a compartment is then better suited to sterilizing a single bottle.
Utilement, la cuve comporte un logement cylindrique de réception du compartiment.Usefully, the tank has a cylindrical housing for receiving the compartment.
Un tel logement cylindrique solidaire de la cuve permet alors de mieux guider le compartiment amovible lors de son positionnement par rapport à la cuve.Such a cylindrical housing integral with the tank then makes it possible to better guide the removable compartment during its positioning relative to the tank.
Avantageusement, ledit logement comporte au moins un orifice latéral venant en communication avec au moins un orifice latéral du compartiment en sa position de circulation complète, orifice qui est obturé par la paroi latérale du compartiment en sa position de circulation restreinte.Advantageously, said housing comprises at least one lateral orifice coming into communication with at least one lateral orifice of the compartment in its position of complete circulation, orifice which is closed by the side wall of the compartment in its position of restricted circulation.
Ainsi, les orifices latéraux assurent une meilleure circulation de la vapeur à l'intérieur de l'enceinte lorsque l'option de circulation complète pour stériliser tous les biberons présents dans l'enceinte est choisie. Par ailleurs, ces orifices sont obturés par la paroi latérale du compartiment afin de conduire la vapeur uniquement à l'intérieur du compartiment lorsque l'option de circulation restreinte a été choisie.Thus, the lateral orifices ensure better circulation of the vapor inside the enclosure when the complete circulation option for sterilizing all the bottles present in the enclosure is chosen. Furthermore, these orifices are closed off by the side wall of the compartment in order to conduct the vapor only inside the compartment when the restricted circulation option has been chosen.
De préférence, ladite enceinte est apte à recevoir au moins deux, de préférence six biberons.Preferably, said enclosure is capable of receiving at least two, preferably six bottles.
Ainsi, avec un tel appareil on peut stériliser au moins un biberon dans l'option de circulation de la vapeur restreinte au compartiment contenant ce biberon. Au moins un deuxième biberon pourrait alors être placé à côté du compartiment dans l'enceinte. Il s'est toutefois avéré avantageux de pouvoir stériliser soit un seul biberon, soit six biberons en même temps (dont un dans le compartiment et cinq agencés dans l'enceinte, autour de ce compartiment), pour un temps de fonctionnement et un volume de cuve optimisés.Thus, with such a device, it is possible to sterilize at least one bottle in the option of circulating the steam restricted to the compartment containing this bottle. At at least a second bottle could then be placed next to the compartment in the enclosure. However, it has proved advantageous to be able to sterilize either a single bottle or six bottles at the same time (including one in the compartment and five arranged in the enclosure, around this compartment), for an operating time and a volume of optimized tank.

L'appareil de stérilisation de biberons selon la présente invention tel que présenté à la figure 1a comporte une cuve 2 munie à son fond d'un élément chauffant électrique 3 apte à porter à ébullition l'eau contenue dans la paroi de fond 4 de forme concave de la cuve 2, formant une cavité de production de vapeur de l'appareil. A titre d'exemple, la puissance de l'élément chauffant électrique 3 est de 850W. L'appareil comporte également un couvercle 5 équipé d'un orifice ou d'une soupape d'échappement de la vapeur (non représentés sur les figures).The bottle sterilization apparatus according to the present invention as presented in FIG. 1a comprises a tank 2 provided at its bottom with an electric heating element 3 capable of bringing to a boil the water contained in the bottom wall 4 of form concave of the tank 2, forming a vapor production cavity of the device. For example, the power of the electric heating element 3 is 850W. The apparatus also includes a cover 5 fitted with an orifice or a steam exhaust valve (not shown in the figures).
L'ensemble couvercle et cuvé définit l'enveloppe extérieure de l'appareil, le couvercle 5 étant emboîté sur la cuve 2. Le même ensemble définit à l'intérieur une enceinte 6 apte à recevoir les biberons à stériliser. Dans une réalisation avantageuse de l'invention, l'enceinte 6 est dimensionnée de manière à pouvoir recevoir six biberons et leurs accessoires. Selon l'invention, l'appareil comporte des moyens de séparation 12 permettant tout d'abord de délimiter un compartiment 14 à l'intérieur de l'enceinte 6. Un tel compartiment 14, mieux visible à la figure 1b, comporte un corps 15 tubulaire cylindrique ouvert en partie supérieure et dont la paroi de fond 18 comporte des orifices inférieurs 19 de passage de la vapeur en provenance de la cuve, tel qu'il sera expliqué par la suite. La paroi latérale du compartiment 14 comporte des orifices latéraux 20 agencés sur une partie de sa circonférence.The cover and cuvé assembly defines the outer envelope of the device, the cover 5 being fitted onto the tank 2. The same assembly defines inside an enclosure 6 capable of receiving the bottles to be sterilized. In an advantageous embodiment of the invention, the enclosure 6 is dimensioned so as to be able to receive six bottles and their accessories. According to the invention, the device comprises separation means 12 making it possible first of all to define a compartment 14 inside the enclosure 6. Such a compartment 14, better visible in FIG. 1b, comprises a body 15 cylindrical tubular open in the upper part and whose bottom wall 18 has lower orifices 19 for the passage of steam from the tank, as will be explained later. The side wall of the compartment 14 has lateral orifices 20 arranged over part of its circumference.
Le compartiment 14 forme Un tube dont le diamètre intérieur est légèrement supérieur à celui extérieur d'un biberon, de manière à pouvoir recevoir un biberon agencé en position renversée, son. ouverture prenant appui sur la paroi de fond 18 du compartiment 14. Le compartiment 14 comporte un support 16 cylindrique à paroi de fond perforée agencé avec son rebord périphérique sur le bord supérieur du compartiment 14. Le support 16 est prévu pour recevoir les accessoires du biberon, tels la tétine, la bague et le capuchon. Le compartiment 14 est fermé par un couvercle 17 muni d'une poignée 21, couvercle qui vient s'emboîter dans l'extrémité libre du corps 15 du compartiment 14. Ainsi assemblé, le compartiment 14 définit un espace fermé à l'intérieur, espace apte à recevoir un biberon et ses accessoires.The compartment 14 forms a tube, the inside diameter of which is slightly greater than that of a bottle, so that it can receive a bottle arranged in the inverted position. opening bearing on the bottom wall 18 of compartment 14. The compartment 14 comprises a cylindrical support 16 with a perforated bottom wall arranged with its peripheral rim on the upper edge of compartment 14. The support 16 is designed to receive the accessories for the bottle , such as the nipple, the ring and the cap. The compartment 14 is closed by a cover 17 provided with a handle 21, a cover which fits into the free end of the body 15 of the compartment 14. Thus assembled, the compartment 14 defines a closed space inside, space suitable for receiving a bottle and its accessories.
La cuve 2 (fig. 1a) est cylindrique, d'axe de rotation vertical, et comporte, au dessus de sa paroi de fond 4, une paroi ajourée 25 inférieure en forme de disque comportant des orifices centraux 26 répartis sur une zone centrale de surface équivalente à celle de la paroi de fond 18 du compartiment 14, ainsi que des orifices périphériques 26' répartis, eux, sur une zone annulaire périphérique comprise entre ladite zone centrale et la périphérie de la paroi ajourée 25. Une paroi ajourée 23 supérieure en forme de disque est placée juste au dessus de la paroi ajourée 25 et comporte, comme la précédente, des orifices centraux 24 répartis sur une zone centrale de surface équivalente à celle de la paroi de fond 18 du compartiment 14, ainsi que des orifices périphériques 24' répartis, eux, sur une zone annulaire périphérique comprise entre ladite zone centrale et la périphérie de la paroi ajourée 23. La paroi ajourée 25 inférieure est montée mobile en rotation par rapport à la paroi ajourée 23 supérieure autour de l'axe longitudinal de la cuve 2.The tank 2 (fig. 1a) is cylindrical, with a vertical axis of rotation, and comprises, above its bottom wall 4, a perforated lower wall 25 in the form of a disc having central orifices 26 distributed over a central zone of surface equivalent to that of the bottom wall 18 of the compartment 14, as well as peripheral orifices 26 'distributed, themselves, over a peripheral annular zone comprised between said central zone and the periphery of the perforated wall 25. A perforated wall 23 above disc shape is placed just above the perforated wall 25 and includes, like the previous one, central orifices 24 distributed over a central area of surface equivalent to that of the bottom wall 18 of compartment 14, as well as peripheral orifices 24 'distributed, them, on a peripheral annular zone between said central zone and the periphery of the perforated wall 23. The lower perforated wall 25 is mounted movable in rotation relative to the upper perforated wall 23 around the axis longitudinal of the tank 2.
Un panier 30 est monté en partie supérieure de l'enceinte 6 et forme support pour les accessoires des biberons à stériliser, les biberons étant placés à l'intérieur de l'enceinte, en dessous du panier 30.A basket 30 is mounted in the upper part of the enclosure 6 and forms a support for the accessories of the bottles to be sterilized, the bottles being placed inside the enclosure, below the basket 30.
Le compartiment 14 est monté amovible par rapport à la cuve 2. Le compartiment 14 présente deux protubérances 22 faisant saillie à l'extérieur et vers le bas par rapport à sa paroi de fond 18. Les protubérances 22 ont une forme carrée, elles traversent avec jeu des ouvertures pratiquées dans la paroi ajourée 23 supérieure et viennent s'emboîter dans des orifices de forme correspondante pratiqués dans la paroi ajourée 25 inférieure. Ainsi, en faisant tourner le compartiment 14, celui-ci entraîne en rotation la paroi ajourée 25 selon deux angles de rotation prédéterminés (ou selon un angle et deux directions de rotation) de manière soit à obturer les orifices périphériques 24' de la paroi ajourée 23 supérieure, soit à faire communiquer les orifices 24' et 26' entre eux pour laisser passer la vapeur en provenance de la cuve 2.The compartment 14 is removably mounted relative to the tank 2. The compartment 14 has two protrusions 22 protruding outside and downward relative to its bottom wall 18. The protrusions 22 have a square shape, they pass through with clearance of the openings made in the upper perforated wall 23 and come to fit in correspondingly shaped orifices made in the lower perforated wall 25. Thus, by rotating the compartment 14, it rotates the perforated wall 25 according to two predetermined angles of rotation (or according to an angle and two directions of rotation) so as either to close the peripheral orifices 24 'of the perforated wall 23 upper, that is to make the orifices 24 'and 26' communicate with each other to let the steam coming from the tank 2 pass.
Au centre de la cuve 2 est disposé un logement 28 tubulaire cylindrique permettant de recevoir et de guider le compartiment 14 lors de sa mise en place sur la paroi ajourée 25 de la cuve 2. Le logement 28 comporte, sur toute ou partie de sa circonférence, des orifices latéraux 29 susceptibles de venir en communication avec les orifices latéraux 20 du compartiment 14, tel qu'il sera expliqué par la suite. Ce logement tubulaire sépare donc l'enceinte en une grande chambre périphérique et une petite chambre centrale pour le compartiment 14.In the center of the tank 2 is disposed a cylindrical tubular housing 28 making it possible to receive and guide the compartment 14 during its positioning on the perforated wall 25 of the tank 2. The housing 28 comprises, over all or part of its circumference , lateral orifices 29 capable of coming into communication with the lateral orifices 20 of the compartment 14, as will be explained below. This tubular housing therefore separates the enclosure into a large peripheral chamber and a small central chamber for compartment 14.
La figure 2a représente l'appareil de l'invention dans un premier mode de fonctionnement. Les biberons 7 ont été disposés avec leurs corps 8 en position retournée, leur ouverture étant placée sur la paroi ajourée 23 de la cuve 2. Les accessoires de ces biberons, tels les tétines 9, les bagues 10 et les capuchons 11 , sont, eux, placés sur le panier 30 au dessus des corps 8 des biberons 7. Le compartiment 14 a été mis en place sur la cuve 2, un corps 8 de biberon et ses accessoires étant placés à l'intérieur du compartiment 14. Lorsque la poignée 21 du compartiment a été actionnée en rotation selon la flèche I, tous les orifices centraux 24 et périphériques 24' de la paroi ajourée 23 ont été mis en communication avec les orifices centraux 26, respectivement périphériques 26' de la paroi ajourée 25. Tous ces orifices laissent passer la vapeur en provenance de la cuve 2. Par la même opération, les orifices latéraux 29 du logement 28 sont unis en communication avec les orifices latéraux 20 du compartiment 14 permettant une circulation de la vapeur en partie médiane de l'enceinte 6. La figure 2b montre par des flèches courbes comment la vapeur circule à l'intérieur de l'enceinte de l'appareil. On remarque sur cette figure que dans la position de rotation I du compartiment 14, la vapeur produite par la cuve 2 circule dans tout le volume de l'enceinte 6 de l'appareil en vue de stériliser les six biberons 7 que l'enceinte contient.Figure 2a shows the apparatus of the invention in a first mode of operation. The bottles 7 were arranged with their bodies 8 in the inverted position, their opening being placed on the perforated wall 23 of the tank 2. The accessories of these bottles, such as the teats 9, the rings 10 and the caps 11, are , placed on the basket 30 above the bodies 8 of the baby bottles 7. The compartment 14 has been put in place on the tank 2, a body 8 of the baby bottle and its accessories being placed inside the compartment 14. When the handle 21 of the compartment has been actuated in rotation according to arrow I, all the central orifices 24 and peripheral 24 ′ of the perforated wall 23 have been placed in communication with the central orifices 26, respectively peripheral 26 ′ of the perforated wall 25. All these orifices let the steam coming from the tank 2. By the same operation, the lateral orifices 29 of the housing 28 are united in communication with the lateral orifices 20 of the compartment 14 allowing a circulation of the steam in the middle part of the enclosure 6. FIG. 2b shows by curved arrows how the steam circulates inside the enclosure of the apparatus. Note in this figure that in the rotational position I of compartment 14, the vapor produced by the tank 2 circulates throughout the volume of the enclosure 6 of the device in order to sterilize the six bottles 7 that the enclosure contains .
La figure 3a représente l'appareil de l'invention dans un deuxième mode de fonctionnement. Un seul biberon a été placé à l'intérieur du compartiment 14 qui a été mis en place comme précédemment sur la cuve 2. Lorsque la poignée 21 du compartiment a été actionnée en rotation selon la flèche II, le compartiment 14 et donc la paroi ajourée 25 reçoivent un déplacement angulaire supplémentaire par rapport au déplacement précédent de manière à ce que la paroi ajourée 25 recouvre les orifices périphériques 24' de la paroi ajourée 23. Lors de la rotation du compartiment 14, la paroi latérale de ce dernier obture les orifices latéraux de passage qui existaient entre le compartiment 14 et le logement 28. Ainsi, les seuls passages de communication entre la cuve 2 et l'enceinte 6 se limitent aux orifices centraux 26 de la paroi ajourée 25 qui communiquent avec les orifices centraux 24 de la paroi ajourée 23 et avec les orifices inférieurs 19 de la paroi de fond du compartiment 14. Ainsi, la vapeur produite par la cuve 2 sert uniquement à stériliser le compartiment 14. La figure 3b montre par des flèches courbes comment la vapeur circule à l'intérieur de l'enceinte de l'appareil. On remarque sur cette figure que dans la position de rotation II du compartiment 14, la vapeur produite par la cuve 2 circule uniquement dans le compartiment 14 assurant ainsi, pour un temps de traitement moindre, la stérilisation d'un seul biberon et de ses accessoires.Figure 3a shows the apparatus of the invention in a second mode of operation. A single bottle was placed inside the compartment 14 which was put in place as previously on the tank 2. When the handle 21 of the compartment was actuated in rotation according to arrow II, the compartment 14 and therefore the perforated wall 25 receive an additional angular displacement with respect to the preceding displacement so that the perforated wall 25 covers the peripheral orifices 24 'of the perforated wall 23. When the compartment 14 is rotated, the side wall of the latter closes the lateral orifices passage which existed between the compartment 14 and the housing 28. Thus, the only communication passages between the tank 2 and the enclosure 6 are limited to the central holes 26 of the perforated wall 25 which communicate with the central holes 24 of the wall perforated 23 and with the lower orifices 19 of the bottom wall of the compartment 14. Thus, the steam produced by the tank 2 is used only to sterilize the c compartment 14. Figure 3b shows by curved arrows how the steam circulates inside the enclosure of the appliance. Note in this figure that in the rotation position II of compartment 14, the steam produced by the tank 2 circulates only in compartment 14 thus ensuring, for a shorter treatment time, the sterilization of a single baby bottle and its accessories.
En fonctionnement, l'utilisateur commence par mettre une quantité d'eau bien déterminée au fond de la cuve 2. Cette quantité d'eau est fonction du mode de fonctionnement choisi par l'utilisateur. Ainsi, pour stériliser les six biberons, on doit verser 120 ml d'eau dans la cuve 2, alors que pour un seul biberon on en verse seulement 70 ml dans la cuve 2. Ensuite, le ou les biberons sont placés à l'intérieur de l'enceinte 6 et l'interrupteur marche/arrêt de l'appareil est enclenché. L'élément chauffant est alimenté en électricité et fait monter la température de l'eau dans la cuve 2 à environ 95 - 98°. La vapeur produite stérilise les objets placés dans l'enceinte 6. Lorsque l'eau du réservoir est évaporée, le thermostat détecte une surchauffe et arrête l'alimentation de l'élément chauffant. Un cycle de stérilisation prend fin à ce moment et les biberons peuvent être utilisés en les sortant de l'appareil.In operation, the user begins by putting a well-determined amount of water at the bottom of the tank 2. This amount of water depends on the operating mode chosen by the user. Thus, to sterilize the six bottles, one must pour 120 ml of water into the tank 2, while for a single bottle one pours only 70 ml into the tank 2. Then, the bottle or bottles are placed inside of speaker 6 and the on / off switch of the device is on. The heating element is supplied with electricity and raises the temperature of the water in tank 2 to around 95 - 98 °. The steam produced sterilizes the objects placed in enclosure 6. When the water in the tank is evaporated, the thermostat detects overheating and stops supplying the heating element. A sterilization cycle ends at this time and the bottles can be used by removing them from the device.
Ainsi, la durée d'un cycle de stérilisation est de 12 min pour stériliser 6 biberons et de seulement 6 min pour stériliser un seul biberon avec l'appareil de l'invention.Thus, the duration of a sterilization cycle is 12 min to sterilize 6 bottles and only 6 min to sterilize a single bottle with the device of the invention.
Le compartiment 14 étant amovible, le biberon et les accessoires qu'il contient peuvent être transportés avec le compartiment, en étant maintenus dans de très bonnes conditions d'hygiène, hors du contact avec des germes ou bactéries qui pourraient les contaminer à nouveau.The compartment 14 being removable, the bottle and the accessories which it contains can be transported with the compartment, being kept in very good hygienic conditions, out of contact with germs or bacteria which could contaminate them again.
La figure 4 représente une vue de dessus d'une variante de réalisation de l'appareil de l'invention, où la cuve 2, le couvercle 5 et le panier 30 ont été retirés pour plus de clarté. On remarque une cuve 2 en forme de portion de cylindre, la zone périphérique 32 cylindrique étant délimitée par une paroi latérale 31 plane. Le compartiment 14 est dans ce cas placé au centre de rotation O du cylindre qui génère la zone périphérique 32, proche de la paroi latérale 31 de la cuve 2. Les biberons, figurés par leurs corps 8, sont alors agencés sur la périphérie en arc de cercle de la cuve 2 en entourant partiellement le compartiment 14. Comme précédemment décrit, le compartiment 14 est solidaire de la paroi ajourée 25 en forme de portion de disque (représentée de manière simplifiée sur la figure pour plus de clarté), qu'il entraîne en rotation. Les flèches I et II indiquent les possibilités de rotation de la paroi ajourée 25 actionnée en rotation par le compartiment 14 autour d'un axe de pivotement passant par le centre de rotation O. Un tel appareil a le même fonctionnement que celui précédemment décrit.Figure 4 shows a top view of an alternative embodiment of the apparatus of the invention, where the tank 2, the cover 5 and the basket 30 have been removed for clarity. There is a tank 2 in the form of a cylinder portion, the cylindrical peripheral zone 32 being delimited by a flat side wall 31. The compartment 14 is in this case placed at the center of rotation O of the cylinder which generates the peripheral zone 32, close to the side wall 31 of the tank 2. The bottles, represented by their bodies 8, are then arranged on the arc periphery of circle of the tank 2 by partially surrounding the compartment 14. As previously described, the compartment 14 is integral with the perforated wall 25 in the form of a disc portion (shown in simplified form in the figure for clarity), which it drives in rotation. The arrows I and II indicate the possibilities of rotation of the perforated wall 25 actuated in rotation by the compartment 14 about a pivot axis passing through the center of rotation O. Such an apparatus has the same operation as that previously described.
D'autres variantes et modes de réalisation de l'invention peuvent être envisagés sans sortir du cadre de ces revendications.Other variants and embodiments of the invention can be envisaged without departing from the scope of these claims.
Ainsi, lorsque le compartiment est retiré de la cuve, il pourrait être remplacé par un biberon placé directement dans l'enceinte et entouré par cinq autres biberons, l'appareil pouvant alors fonctionner comme un stérilisateur à six biberons.Thus, when the compartment is removed from the tank, it could be replaced by a bottle placed directly in the enclosure and surrounded by five other bottles, the device then being able to function as a sterilizer with six bottles.
Dans une autre variante, le compartiment peut être délimité dans l'enceinte simplement en disposant un gabarit dans l'enceinte (par gabarit on comprend un corps de forme et dimensions adaptées à celles de l'enceinte) qui est apte à obturer une partie des orifices de la paroi qui sépare l'enceinte de la cavité de production de vapeur. Ainsi la vapeur produite est envoyée uniquement dans un compartiment de volume réduit, via un nombre restreint d'orifices communicants. In another variant, the compartment can be delimited in the enclosure simply by placing a template in the enclosure (by template we understand a body of shape and dimensions adapted to those of the enclosure) which is capable of sealing off part of the orifices in the wall which separates the enclosure from the steam production cavity. Thus the steam produced is sent only in a compartment of reduced volume, via a limited number of communicating orifices.
