Description

APPAREIL DE CUISSON A CUVE COMPORTANT UN DISPOSITIF DE TANK COOKING APPARATUS COMPRISING A DEVICE
VIDANGE AVEC FILTREDRAINING WITH FILTER
La présente invention se rapporte au domaine technique général des appareils de cuisson comportant une cuve prévue pour recevoir un bain de cuisson. La présente invention concerne plus particulièrement les appareils du type précité comprenant un dispositif de vidange du bain de cuisson contenu dans la cuve.The present invention relates to the general technical field of cooking appliances comprising a tank designed to receive a cooking bath. The present invention relates more particularly to devices of the aforementioned type comprising a device for emptying the cooking bath contained in the tank.
La présente invention concerne notamment, mais non exclusivement, les friteuses. En effet le bain de cuisson n'est pas limité à un bain d'huile ou de matière grasse fondue, mais peut également consister en toute matière alimentaire suffisamment fluide pour s'écouler par un dispositif de vidange, et en particulier un liquide à base d'eau.The present invention relates in particular, but not exclusively, to fryers. In fact, the cooking bath is not limited to a bath of oil or of melted fat, but can also consist of any food material sufficiently fluid to flow through a draining device, and in particular a liquid based of water.
Il est connu du document DE 93 15764 U une friteuse dont la cuve comporte un conduit de vidange équipé d'un filtre. L'embouchure du conduit de vidange est solidarisée de manière démontable avec la cuve. Le filtre est monté amovible sur l'embouchure du conduit à l'intérieur de la cuve. Une vanne de vidange est prévue à l'extérieur du boîtier de la friteuse.Document DE 93 15764 U discloses a fryer, the tank of which has a drain pipe fitted with a filter. The mouth of the drain pipe is detachably secured to the tank. The filter is removably mounted on the mouth of the conduit inside the tank. A drain valve is provided on the outside of the fryer housing.
Il est connu du document US 5 404 799 une friteuse à filtration continue comportant une cuve munie d'un dispositif de vidange démontable. Le dispositif de vidange comporte un corps agencé au moins en partie à l'extérieur de la cuve. Ce corps est assemblé de manière démontable avec une couronne maintenant un filtre, la couronne étant agencée à l'intérieur de la cuve. De ce fait, le filtre peut être retiré alors que le corps reste en place. L'utilisation du dispositif de vidange en l'absence du filtre est donc possible.Document US Pat. No. 5,404,799 discloses a continuous filtration fryer comprising a tank provided with a removable emptying device. The emptying device comprises a body arranged at least partially outside the tank. This body is assembled in a removable manner with a crown holding a filter, the crown being arranged inside the tank. As a result, the filter can be removed while the body remains in place. It is therefore possible to use the draining device in the absence of the filter.
L'objet de la présente invention est de simplifier le nettoyage d'un appareil de cuisson comportant une cuve associée à un dispositif de vidange comprenant un filtre.The object of the present invention is to simplify the cleaning of a cooking appliance comprising a tank associated with a drainage device comprising a filter.
Ces objets sont atteints avec un appareil de cuisson comportant dans un boîtier une cuve prévue pour recevoir un bain de cuisson, munie d'un dispositif de vidange démontable comportant un filtre, du fait que le dispositif de vidange comporte un corps, agencé au moins en partie à l'extérieur de la cuve, assemblé de manière démontable avec une couronne agencée au moins en partie à l'intérieur de la cuve, le filtre fermant la couronne et étant fixé sur ladite couronne. Ces dispositions permettent à l'utilisateur de désolidariser la cuve et le dispositif de vidange pour le nettoyage. Grâce à l'assemblage solidaire de la couronne et du filtre, l'utilisateur ne peut remonter le dispositif de vidange sans remettre le filtre. La couronne peut par exemple être surmoulée autour du filtre.These objects are achieved with a cooking appliance comprising in a housing a tank designed to receive a cooking bath, provided with a removable drainage device comprising a filter, owing to the fact that the drainage device comprises a body, arranged at least partly outside the tank, assembled in a removable manner with a crown arranged at least partly inside the tank, the filter closing the crown and being fixed on said crown. These provisions allow the user to separate the tank and the emptying device for cleaning. Thanks to the integral assembly of the crown and the filter, the user cannot reassemble the emptying device without replacing the filter. The crown can for example be molded around the filter.
Avantageusement alors le corps et la couronne comportent des rampes prévues pour un assemblage de type baïonnette. Un assemblage par vissage peut également être envisagé.Advantageously then the body and the crown comprise ramps provided for a bayonet type assembly. A screw connection can also be considered.
Avantageusement encore un joint annulaire solidaire du corps, respectivement de la couronne, est comprimé contre la cuve lorsque la couronne est assemblée avec le corps. Cette disposition permet de limiter les risques de perte du joint lors du démontage ou d'oubli du joint lors du remontage du dispositif de vidange.Advantageously, an annular seal integral with the body, respectively with the crown, is compressed against the tank when the crown is assembled with the body. This arrangement makes it possible to limit the risks of loss of the seal during disassembly or forgetting of the seal during reassembly of the emptying device.
Avantageusement encore le corps est réalisé en matière plastique résistant à la température du bain de cuisson. Cette disposition permet de faciliter la réalisation du corps et aussi de limiter les risques de brûlure de l'utilisateur lors de la manipulation du corps après une vidange, du fait de la capacité calorifique des matières plastiques plus faible que celle de l'aluminium.Advantageously also, the body is made of plastic material resistant to the temperature of the cooking bath. This arrangement makes it easier to produce the body and also to limit the risk of burns for the user when handling the body after emptying, due to the lower calorific capacity of plastics than that of aluminum.
Avantageusement encore, pour faciliter le nettoyage, la cuve est amovible par rapport au boîtier. En alternative, le boîtier peut comprendre une partie supérieure solidaire de la cuve et amovible par rapport à une partie inférieure.Advantageously also, to facilitate cleaning, the tank is removable relative to the housing. Alternatively, the housing may include an upper part secured to the tank and removable with respect to a lower part.
Avantageusement encore, le dispositif de vidange comporte un clapet, ledit clapet étant relié à un bouton de manœuvre par l'intermédiaire d'un mécanisme de commande. Le clapet permet la vidange du bain de cuisson contenu dans la cuve.Advantageously also, the emptying device comprises a valve, said valve being connected to an operating button by means of a control mechanism. The valve allows the emptying of the cooking bath contained in the tank.
Avantageusement alors, le clapet peut être désaccouplé du mécanisme de commande. Le mécanisme de commande est alors solidaire du boîtier ou d'un élément agencé dans le boîtier, par exemple un réceptacle prévu pour la récupération du bain de cuisson, cet élément pouvant être amovible du boîtier.Advantageously then, the valve can be uncoupled from the control mechanism. The control mechanism is then secured to the housing or to a element arranged in the housing, for example a receptacle provided for recovering the cooking bath, this element being able to be removable from the housing.
Avantageusement encore, le clapet est un clapet à ressort. Cette disposition permet de garantir la fermeture du clapet lors du retrait de la cuve.Advantageously also, the valve is a spring valve. This arrangement ensures that the valve is closed when the tank is removed.
Avantageusement encore, le dispositif de vidange comporte un clapet thermostatique. Un clapet thermostatique comporte un organe mécanique thermosensible mobile en fonction de la température. Le filtre permet de protéger le clapet thermostatique en empêchant les particules présentes dans le bain de cuisson d'atteindre ledit clapet lors de la vidange du bain de cuisson.Advantageously also, the emptying device comprises a thermostatic valve. A thermostatic valve comprises a thermosensitive mechanical member movable as a function of the temperature. The filter protects the thermostatic valve by preventing particles present in the cooking bath from reaching said valve when the cooking bath is emptied.
Avantageusement encore, pour faciliter le nettoyage, le corps est amovible par rapport à la cuve.Advantageously also, to facilitate cleaning, the body is removable relative to the tank.
Avantageusement encore le corps est assemblé directement avec la couronne notamment par baïonnette ou par vissage. Cette disposition permet de faciliter le remontage du dispositif de vidange.Advantageously also, the body is assembled directly with the crown, in particular by bayonet or by screwing. This arrangement makes it easier to reassemble the emptying device.

Le dispositif de vidange 10 comprend un conduit d'évacuation 15 issu du fond de la cuve 2. Le conduit 15 est protégé par un filtre 14. Un clapet à ressort 20 obture la partie inférieure du conduit 15. Un clapet thermostatique 16 est agencé entre le filtre 14 et le clapet à ressort 20.The emptying device 10 comprises a discharge pipe 15 coming from the bottom of the tank 2. The pipe 15 is protected by a filter 14. A spring-loaded valve 20 closes the lower part of the pipe 15. A thermostatic valve 16 is arranged between the filter 14 and the spring valve 20.
Le conduit 15 est formé par un corps 11 avantageusement réalisé en une matière plastique résistante aux températures élevées du bain de cuisson, par exemple de l'Amodel résistant jusqu'à 250°C dans le cas d'une friteuse. Le corps 11 est monté amovible par rapport la cuve 2. Un joint 19 est interposé entre la cuve 2 et le corps 11. Le joint 19 est avantageusement solidaire du corps 11 pour éviter une perte lors du démontage du dispositif de vidange ou un oubli lors du remontage dudit dispositif.The conduit 15 is formed by a body 11 advantageously made of a plastic material resistant to the high temperatures of the cooking bath, for example Amodel resistant up to 250 ° C. in the case of a fryer. The body 11 is removably mounted relative to the tank 2. A seal 19 is interposed between the tank 2 and the body 11. The seal 19 is advantageously secured to the body 11 to avoid loss during disassembly of the emptying device or an oversight during reassembly of said device.
Le filtre 14 est monté amovible par rapport à la cuve 2 et au corps 11. Selon l'exemple de réalisation illustré aux figures, le filtre 14 est solidaire d'une couronne 13 assemblée par baïonnette avec le corps 11. La couronne 13 est logée de manière amovible dans un renfoncement du fond de la cuve 2. La couronne 13 est immobilisée en rotation par rapport à la cuve 2. La partie supérieure du corps 11 est engagée dans une ouverture ménagée dans le fond de la cuve 2, et porte des rampes 11a coopérant avec des rampes 13a de la couronne 13 pour former l'assemblage par baïonnette. Le clapet thermostatique 16 comprend une coupelle bimétallique à retournement 17 fixée sur la face inférieure d'une plaque perforée 18 obturant l'extrémité supérieure du corps 11. La plaque 18 est par exemple sertie à l'intérieur du corps 11.The filter 14 is removably mounted relative to the tank 2 and to the body 11. According to the embodiment illustrated in the figures, the filter 14 is secured to a crown 13 assembled by bayonet with the body 11. The crown 13 is housed removably in a recess in the bottom of the tank 2. The crown 13 is immobilized in rotation relative to the tank 2.

A titre d'exemple, cette coupelle est réalisée à partir un laminé bimétallique et présente un diamètre de 30 mm. En position fermée, la coupelle 17 est incurvée vers le bas et sa périphérie vient en appui contre un épaulement annulaire interne 12 du corps 11. Le clapet 16 est donc fermé. En position ouverte, la coupelle 17 est incurvée dans l'autre sens, donc vers le haut, et ménage un passage vers les orifices de la plaque perforée 18. Le liquide peut alors traverser le clapet thermostatique 16.For example, this cup is made from a bimetallic laminate and has a diameter of 30 mm. In the closed position, the cup 17 is curved downwards and its periphery bears against an internal annular shoulder 12 of the body 11. The valve 16 is therefore closed. In the open position, the cup 17 is curved in the other direction, therefore upwards, and provides a passage towards the orifices of the perforated plate 18. The liquid can then pass through the thermostatic valve 16.
Le clapet à ressort 20 comporte une pièce mobile d'obturation 21 équipée d'un joint périphérique torique 22. La pièce 21 est montée sur un ressort 23 s'appuyant contre la face inférieure de la coupelle 17.

L'appareil comporte un autre dispositif de sécurité 50 destiné à empêcher deux vidanges consécutives.The device includes another safety device 50 intended to prevent two consecutive emptying.
A cet effet une pièce mobile de sécurité 51 est agencée entre le boîtier 1 et le réceptacle de vidange 3. La pièce 51 est guidée en translation longitudinale par des butées de guidage 52. Le mouvement longitudinal de la pièce 51 est limité par des butées d'arrêt 53. Une lame flexible supérieure montée sur la pièce 51 est prévue pour venir en butée contre le réceptacle de vidange 3 lors de la mise en place dudit réceptacle dans le boîtier 1 , puis pour prendre appui contre le réceptacle de vidange 3 lorsque la pièce 51 est bloquée par l'une des butées 53.To this end, a movable safety piece 51 is arranged between the housing 1 and the drain receptacle 3. The piece 51 is guided in longitudinal translation by guide stops 52. The longitudinal movement of the piece 51 is limited by stops d 'stop 53. An upper flexible blade mounted on the part 51 is designed to abut against the drain receptacle 3 during the setting in place of said receptacle in the housing 1, then to bear against the emptying receptacle 3 when the part 51 is blocked by one of the stops 53.
La pièce 51 comporte une première came 55 prévue pour coopérer avec une patte 48 issue de la pièce mobile de commande 42 lorsque le bouton de manœuvre 45 est amené en position de vidange après la mise en place du réceptacle de vidange 3. La pièce 51 comporte une deuxième came 56 prévue pour coopérer avec la patte 48 lorsque le bouton de manœuvre 45 est ramené en position d'utilisation après une vidange. La pièce 51 comporte une butée de blocage 57 prévue pour bloquer la rotation de la pièce mobile de commande 42 lorsque le bouton de manœuvre 45 est ramené vers la position de vidange après une nouvelle utilisation sans retrait du réceptacle de vidange 3.The part 51 comprises a first cam 55 intended to cooperate with a lug 48 issuing from the movable control part 42 when the operating button 45 is brought into the emptying position after the emptying receptacle 3 has been put in place. The part 51 comprises a second cam 56 provided to cooperate with the tab 48 when the operating button 45 is returned to the position of use after emptying. The part 51 comprises a blocking stop 57 provided for blocking the rotation of the movable control part 42 when the operating button 45 is returned to the emptying position after a new use without removing the emptying receptacle 3.
Le dispositif de sécurité 50 interdit de procéder à une deuxième vidange si le réceptacle de vidange 3 n'a pas été retiré au moins partiellement du boîtier 1 puis remis en place, grâce aux déplacements de la pièce 51 lors de la manœuvre du dispositif de commande 40 de la position d'utilisation vers la position de vidange et retour, ainsi que lors du retrait puis de la remise en place du réceptacle de vidange 3.The safety device 50 prohibits carrying out a second emptying if the emptying receptacle 3 has not been at least partially removed from the casing 1 and then replaced, by virtue of the movements of the part 51 during the operation of the control device 40 from the use position to the emptying and return position, as well as when removing and then replacing the emptying receptacle 3.
La présente réalisation fonctionne de la manière suivante.The present embodiment operates in the following manner.
L'utilisateur peut retirer la cuve 2 du boîtier 1 quelle que soit la position du bouton de manœuvre 45, le clapet à ressort 20 pouvant être désaccouplé du mécanisme de commande 40. Lorsque le bouton de manœuvre 45 occupe la position de vidange montrée aux figures 1 et 4, le clapet à ressort 20 referme le conduit 15 lors du retrait de la cuve 2, du fait que la came 44 ne repousse plus la pièce mobile d'obturation 21. L'utilisateur peut ensuite démonter le dispositif de vidange 10 pour le nettoyer en tournant le corps 11 par rapport à la couronne 13.The user can remove the tank 2 from the housing 1 whatever the position of the operating button 45, the spring valve 20 being able to be uncoupled from the control mechanism 40. When the operating button 45 occupies the emptying position shown in the figures 1 and 4, the spring-loaded valve 20 closes the duct 15 when the tank 2 is withdrawn, because the cam 44 no longer pushes the movable closure part 21. The user can then dismantle the emptying device 10 to clean it by turning the body 11 relative to the crown 13.
Le filtre 14 solidaire de la couronne 13 interdit tout remontage du dispositif de vidange 10 sur la cuve 2 en l'absence du filtre 14. Le joint annulaire 19 solidaire du corps 11 évite que l'utilisateur oublie le joint 19 lors du remontage du dispositif de vidange 10 sur la cuve 2.The filter 14 secured to the crown 13 prohibits any reassembly of the emptying device 10 on the tank 2 in the absence of the filter 14. The annular seal 19 secured to the body 11 prevents the user forgetting the seal 19 during reassembly of the emptying device 10 on the tank 2.
A titre de variante, le joint annulaire 19 peut être solidaire de la couronne 13 ou encore être indépendant.Alternatively, the annular seal 19 can be integral with the crown 13 or even be independent.
A titre de variante, le corps 11 peut être immobilisé en rotation par rapport à la cuve, et la couronne 13 peut être tournée par l'utilisateur.As a variant, the body 11 can be immobilized in rotation relative to the tank, and the crown 13 can be rotated by the user.
A titre de variante, le corps 11 pourrait être assemblé directement avec la couronne 13 par d'autres moyens qu'un assemblage par baïonnette, notamment par vissage.Alternatively, the body 11 could be assembled directly with the crown 13 by means other than assembly by bayonet, in particular by screwing.
A titre de variante, le clapet à ressort 20 pourrait être remplacé par une vanne comportant un dispositif de manœuvre.As a variant, the spring valve 20 could be replaced by a valve comprising an operating device.
A titre de variante, le clapet thermostatique 16 pourrait être supprimé.Alternatively, the thermostatic valve 16 could be omitted.
A titre de variante, le réceptacle de vidange 3 peut former un socle recevant de manière amovible le boîtier entourant la cuve.As a variant, the emptying receptacle 3 can form a base removably receiving the housing surrounding the tank.
La présente invention n'est nullement limitée à l'exemple de réalisation décrit et à ses variantes, mais englobe de nombreuses modifications dans le cadre des revendications. The present invention is in no way limited to the example of embodiment described and to its variants, but encompasses numerous modifications within the scope of the claims.
