Abstract
Description
La présente invention concerne un four, et plus particulièrement un four à micro-ondes.The present invention relates to an oven, and more particularly to a microwave oven.
Lors de la cuisson d'un aliment, liquide ou solide, dans une cavité de four à micro-ondes, une forte quantité de vapeur est générée rapidement et en continu. Cette vapeur se diffuse dans la cavité du four et finit par se condenser et s'accumuler sur les parois de la cavité ou la vitre de la porte.When cooking a food, liquid or solid, in a microwave oven cavity, a large amount of steam is generated rapidly and continuously. This vapor diffuses into the cavity of the oven and eventually condenses and accumulates on the walls of the cavity or the glass door.
La présence de vapeur d'eau génère des problèmes sur le plan esthétique, dès lors que la vision des aliments à travers la vitre de la porte est réduite, et sur le plan de la sécurité, la vapeur pouvant être diffusée dans toute l'enceinte du four, et notamment sur des parties électriques.The presence of water vapor causes aesthetic problems, as the vision of food through the glass door is reduced, and in terms of safety, the vapor can be diffused throughout the enclosure oven, and especially on electrical parts.
Pour pallier ce problème, il est connu de ventiler la cavité pour évacuer la vapeur et évaporer la condensation formée.To overcome this problem, it is known to ventilate the cavity to evacuate the vapor and evaporate the condensation formed.
Un système de ventilation est ainsi associé à la cavité, la cavité comportant des moyens d'entrée d'air et des moyens de sortie d'air aspiré par le système de ventilation.A ventilation system is thus associated with the cavity, the cavity comprising air inlet means and air outlet means sucked by the ventilation system.
On connaît également un four tel que décrit dans le document
Ces moyens d'entrée et de sortie d'air sont généralement constitués d'ouvertures réalisées dans la cavité et disposées par exemple dans des parois opposées de la cavité.These air inlet and outlet means generally consist of openings made in the cavity and arranged for example in opposite walls of the cavity.
Cependant, ces systèmes de ventilation présentent des zones mortes de ventilation dans la cavité, favorisant la condensation de la vapeur.However, these ventilation systems have dead zones of ventilation in the cavity, favoring the condensation of the steam.
La présente invention a pour but de résoudre les inconvénients précités et de proposer un four avec une ventilation optimale de la cavité permettant de garantir l'absence de condensation dans celle-ci.The present invention aims to solve the aforementioned drawbacks and to provide an oven with an optimal ventilation of the cavity to ensure the absence of condensation therein.
A cet effet, la présente invention vise un four comprenant une cavité adaptée à recevoir des aliments à chauffer et un système de ventilation de la cavité, cette cavité comportant des moyens d'entrée d'air et des moyens de sortie d'air disposés dans une paroi de la cavité.For this purpose, the present invention provides an oven comprising a cavity adapted to receive food to be heated and a ventilation system of the cavity, this cavity comprising air inlet means and air outlet means disposed in a wall of the cavity.
Selon l'invention, les moyens d'entrée d'air et les moyens de sortie d'air s'étendent dans une même portion de la paroi, cette portion ayant une surface inférieure à un tiers de la surface totale de la paroi.According to the invention, the air inlet means and the air outlet means extend in the same portion of the wall, this portion having an area less than one third of the total surface of the wall.
Il est ainsi possible de disposer les moyens d'entrée d'air et les moyens de sortie d'air de façon rapprochée.It is thus possible to arrange the air inlet means and the air outlet means in a close manner.
En positionnant les moyens d'entrée et de sortie d'air à proximité les uns des autres, il est possible d'assurer une ventilation complète de la cavité, sans zone morte.By positioning the air inlet and outlet means in proximity to each other, it is possible to ensure complete ventilation of the cavity, without dead zone.
Cette circulation de l'air permet de créer un rideau d'air entre les parois de la cavité et les aliments chauffés, source de vapeur.This circulation of air creates a curtain of air between the walls of the cavity and heated food source of steam.
II est ainsi possible d'isoler complètement la source de vapeur par rapport aux parois de la cavité et d'éviter ainsi la condensation d'eau sur ces parois.It is thus possible to completely isolate the source of steam with respect to the walls of the cavity and thus avoid the condensation of water on these walls.
Dans un mode de réalisation particulièrement pratique de l'invention, les moyens d'entrée d'air et les moyens de sortie d'air sont disposés dans la paroi supérieure de la cavité du four et s'étendent dans la largeur du four.In a particularly practical embodiment of the invention, the air inlet means and the air outlet means are disposed in the upper wall of the oven cavity and extend in the width of the oven.
Par ailleurs, le système de ventilation est adapté à créer un flux d'air ayant une vitesse au niveau des moyens d'entrée d'air dans la cavité comprise entre 0,5 et 4 m/s, et de préférence égale à 1 m/s.Furthermore, the ventilation system is adapted to create a flow of air having a velocity at the level of the air inlet means in the cavity of between 0.5 and 4 m / s, and preferably equal to 1 m / s.
On observe alors une efficacité accrue du système de ventilation et de la suppression de la vapeur sur les parois pour des vitesses d'entrée d'air importantes. Ce type de ventilation est particulièrement bien adapté à la ventilation de cavités de grand volume.There is then an increased efficiency of the ventilation system and the removal of steam on the walls for high air inlet speeds. This type of ventilation is particularly well suited to ventilation of large cavities.
En garantissant une vitesse du flux d'air au niveau des moyens d'entrée d'air suffisamment importante, le flux d'air ne risque pas de boucler directement entre les moyens d'entrée d'air et les moyens de sortie d'air, mais circule en assurant une ventilation complète de la cavité.By guaranteeing a speed of the air flow at the level of the sufficiently large air inlet means, the air flow is not likely to loop directly between the air intake means and the air outlet means. but circulates by providing complete ventilation of the cavity.
D'autres particularités et avantages de l'invention apparaîtront encore dans la description ci-après.Other features and advantages of the invention will become apparent in the description below.

On va décrire à présent en référence aux figures 1 et 2 un mode de réalisation d'un four conforme la présente invention.An embodiment of an oven according to the present invention will now be described with reference to FIGS. 1 and 2.
Dans l'exemple décrit ci-dessous, on considère que le four est un four à micro-ondes.In the example described below, it is considered that the oven is a microwave oven.
Ce four comprend une cavité 10 adaptée à recevoir des aliments à chauffer.This oven comprises a
Cette cavité est fermée sur une face avant par une porte 11, comprenant de préférence une surface vitrée permettant de visualiser l'intérieur de la cavité pendant le chauffage ou la cuisson des aliments.This cavity is closed on a front face by a
Cette cavité est généralement de forme sensiblement parallélépipédique, de volume plus ou moins important égal par exemple à 21 I, ou 24 I ou même 30 I.This cavity is generally of substantially parallelepipedal shape, of greater or lesser volume, for example equal to 21 I, or 24 I or even 30 I.
A titre d'exemple non limitatif, les dimensions de la cavité peuvent être de 420 mm en largeur, de 230 mm en hauteur et de 410 mm en profondeur.By way of non-limiting example, the dimensions of the cavity may be 420 mm in width, 230 mm in height and 410 mm in depth.
Un système de ventilation est associé à la cavité.A ventilation system is associated with the cavity.
Ce système de ventilation sera décrit ultérieurement en référence à la figure 2.This ventilation system will be described later with reference to FIG.
Afin d'assurer la ventilation de la cavité, celle-ci comporte des moyens d'entrée d'air 13 et des moyens de sortie d'air 14.In order to ensure the ventilation of the cavity, the latter comprises air inlet means 13 and air outlet means 14.
Comme bien illustré sur les figures, ces moyens d'entrée d'air 13 sont disposés dans une paroi 10a de la cavité 10, à proximité des moyens de sortie d'air 14.As is well illustrated in the figures, these air inlet means 13 are arranged in a
Dans ce mode de réalisation, les moyens d'entrée d'air 13 et les moyens de sortie d'air 14 sont disposés dans la même paroi 10a de la cavité.In this embodiment, the air inlet means 13 and the air outlet means 14 are disposed in the
Lorsque ces moyens d'entrée d'air 13 et ces moyens de sortie d'air 14 sont disposés dans une même paroi, il est possible de s'assurer de leur proximité les uns des autres dès lors que ces moyens d'entrée d'air 13 et ces moyens de sortie d'air 14 s'étendent dans une même portion de la paroi 10a, cette portion ayant une surface inférieure à un tiers de la surface totale de la paroi 10a.When these air inlet means 13 and these air outlet means 14 are arranged in the same wall, it is possible to ensure their proximity to each other since these means of entry of
Afin d'assurer une ventilation dans toute la largeur de la cavité, les moyens d'entrée d'air 13 et les moyens de sortie d'air 14 s'étendent suivant respectivement deux directions parallèles l'une à l'autre, et ici parallèles à la largeur du four.To ensure ventilation throughout the width of the cavity, the air inlet means 13 and the air outlet means 14 extend respectively in two directions parallel to one another, and here parallel to the width of the oven.
Dans ce mode de réalisation pratique, les moyens d'entrée d'air 13 et les moyens de sortie d'air 14 sont constitués d'une série de perforations alignées suivant une direction qui s'étend dans la largeur du four. La représentation de ces perforations sur les figures n'est nullement limitative. En particulier, les moyens d'entrée d'air 13 et les moyens de sortie d'air 14 peuvent être constitués de perforations identiques.In this practical embodiment, the air inlet means 13 and the air outlet means 14 consist of a series of perforations aligned in a direction that extends in the width of the furnace. The representation of these perforations in the figures is in no way limiting. In particular, the air inlet means 13 and the air outlet means 14 may consist of identical perforations.
En pratique, ces moyens d'entrée d'air 13 et ces moyens de sortie d'air 14 sont séparés d'une distance relativement faible, et par exemple inférieure à 7 cm.In practice, these air inlet means 13 and these air outlet means 14 are separated by a relatively small distance, and for example less than 7 cm.
Cette distance peut être égale à 5 cm dans le cas présent où la profondeur du four est de l'ordre de 41 cm.This distance may be equal to 5 cm in the present case where the depth of the oven is of the order of 41 cm.
De préférence, les moyens d'entrée d'air 13 sont adjacents à la porte de façade 11 adaptée à fermer la cavité 10.Preferably, the air inlet means 13 are adjacent to the
Ainsi, l'air entrant dans la cavité est adapté à circuler sur la face intérieure de la porte 11, et évite ainsi tout dépôt de condensation notamment sur la surface vitrée.Thus, the air entering the cavity is adapted to flow on the inner face of the
Comme bien illustré sur la figure 2, grâce à la disposition adjacente des moyens d'entrée d'air 13 et des moyens de sortie d'air 14, il est possible d'assurer la ventilation complète de la cavité comme bien illustré par les flèches. Le flux d'air réalise ainsi une boucle dans la cavité, longeant chaque paroi de la cavité afin de créer un rideau d'air entre les aliments A chauffés dans la cavité et générant de la vapeur, et les parois de la cavité.As is well illustrated in FIG. 2, thanks to the adjacent arrangement of the air intake means 13 and the air outlet means 14, it is possible to ensure the complete ventilation of the cavity as well illustrated by the arrows. . The air flow thus makes a loop in the cavity, along each wall of the cavity to create a curtain of air between the food A heated in the cavity and generating steam, and the walls of the cavity.
Le flux d'air est suffisamment puissant pour éviter que l'air ne boucle directement entre les moyens d'entrée d'air 13 et les moyens de sortie d'air 14 disposés dans la paroi supérieure 10a de la cavité 10.The air flow is sufficiently powerful to prevent the air from looping directly between the air inlet means 13 and the air outlet means 14 disposed in the
Ainsi, le système de ventilation est adapté à créer un flux d'air ayant une vitesse au niveau des moyens d'entrée d'air 13 comprise entre 0,5 et 4 m/s. Cette vitesse est de préférence égale à 1 m/s.Thus, the ventilation system is adapted to create a flow of air having a speed at the air inlet means 13 between 0.5 and 4 m / s. This speed is preferably equal to 1 m / s.
On a illustré sur la figure 2 un exemple de système de ventilation adapté à ventiler un four à micro-ondes.There is illustrated in Figure 2 an example of a ventilation system adapted to ventilate a microwave oven.
Dans ce mode de réalisation, le système de ventilation comprend en particulier un double ventilateur 15 adapté à alimenter deux circuits de ventilation.In this embodiment, the ventilation system comprises in particular a
Un premier circuit de circulation d'air, représenté par des flèches noires sur la figure 2, est adapté à refroidir des composants électroniques situés en partie haute du four et à assurer la ventilation de la cavité comme décrit précédemment.A first air circulation circuit, represented by black arrows in FIG. 2, is adapted to cool electronic components situated in the upper part of the oven and to ventilate the cavity as previously described.
Pour cela, dans ce mode de réalisation, une plaque intermédiaire 16 est disposée entre la paroi supérieure 10a de la cavité et la paroi extérieure 17 de la carrosserie du four.For this, in this embodiment, an
Un guide d'air 18 s'étend entre le ventilateur 15 et l'entrée d'air 13 dans la cavité. En particulier, dans ce guide d'air 18 est monté dans cet exemple le magnétron 19, générateur de micro-ondes, afin d'assurer son refroidissement.An
L'air alimentant le ventilateur 15 est aspiré au niveau d'une ouverture en façade située entre la porte du four 11 et un bandeau de commande 20. Cet air aspiré au niveau de l'entrée d'air de façade 21 circule en partie dans le conduit d'air 18 pour refroidir le magnétron 19 et est introduit avec une vitesse suffisante au niveau des moyens d'entrée d'air 13 dans la cavité. L'air est ensuite évacué de la cavité au niveau des moyens de sortie d'air 14 et circule entre la paroi supérieure 10a de la cavité et la tôle intermédiaire 16. Cet air est ensuite évacué au niveau de l'espace existant entre les parois latérales de la cavité et la carrosserie du four pour sortir en partie basse du four, comme illustré par les flèches blanches et noires.The air supplying the
Un second circuit de circulation d'air est mis en oeuvre à partir du ventilateur 15 dans la partie arrière du four comme illustré par les flèches blanches. L'air refoulé entre la paroi arrière 10b de la cavité et la carrosserie du four permet de refroidir les composants du four micro-ondes (transformateur, condensateur haute tension) ainsi que les éléments liés par exemple à un fonctionnement du four avec chaleur tournante.A second air circulation circuit is implemented from the
Comme précédemment, l'air est également évacué au niveau des parois latérales du four et en partie basse comme illustré au niveau des flèches blanches et noires.As before, the air is also discharged at the side walls of the oven and at the bottom as shown at the white and black arrows.
Dans un four à micro-ondes, la ventilation de la cavité est notamment nécessaire pendant un cycle de cuisson par micro-ondes dès lors que ce type de cuisson dégage une quantité de vapeur importante.In a microwave oven, ventilation of the cavity is particularly necessary during a microwave cooking cycle when this type of cooking releases a significant amount of steam.
On notera que si le four est utilisé selon un mode de cuisson traditionnel (chaleur tournante, gril) ou un mode combinant la génération de micro-ondes et des éléments radiants, la ventilation de la cavité n'est pas nécessaire.Note that if the oven is used in a traditional cooking mode (rotating heat, grill) or a mode combining the generation of microwaves and radiant elements, ventilation of the cavity is not necessary.
Grâce à cette ventilation complète de la cavité, il n'y a pas de zone morte et une isolation complète de la source de vapeur A par rapport à la cavité peut être obtenue.Thanks to this complete ventilation of the cavity, there is no dead zone and complete isolation of the source of vapor A with respect to the cavity can be obtained.
Ce mode de réalisation est particulièrement bien adapté pour des vitesses d'entrée d'air importantes, et par conséquent pour des cavités de grand volume, de l'ordre de 30 I.This embodiment is particularly well suited for large air inlet velocities, and therefore for cavities with a large volume, of the order of 30 I.
La Demanderesse a par ailleurs constaté que, même pour des vitesses très importantes de l'ordre de 4 m/s, la circulation du flux d'air reste laminaire et permet de réaliser un rideau d'air sur l'ensemble des parois de la cavité.The Applicant has also found that, even for very high speeds of the order of 4 m / s, the circulation of the air flow remains laminar and allows for a curtain of air on all the walls of the cavity.
Bien entendu, de nombreuses modifications peuvent être apportées à l'exemple de réalisation décrit précédemment sans sortir du cadre de l'invention.Of course, many modifications can be made to the embodiment described above without departing from the scope of the invention.
En particulier, la distance séparant les moyens d'entrée d'air 13 et les moyens de sortie d'air 14 peut être adaptée à la cavité. Ainsi, plus cette distance est importante, plus la surface d'une zone morte non ventilée va être importante. En outre, plus la vitesse d'entrée de l'air aspiré par le système de ventilation est importante, plus la distance entre les moyens d'entrée d'air 13 et les moyens de sortie d'air 14 peut être réduite.In particular, the distance separating the air inlet means 13 and the air outlet means 14 may be adapted to the cavity. Thus, the greater this distance, the larger the area of a non-ventilated dead zone will be important. In addition, the greater the air inlet velocity sucked by the ventilation system, the greater the distance between the air inlet means 13 and the air outlet means 14 can be reduced.
En outre, dans la cavité, une plaque formant déflecteur pourrait être ajoutée, à proximité des moyens d'entrée d'air 13. Cette plaque peut permettre une meilleure orientation du flux d'air en entrée, vers la porte de la cavité afin que l'écoulement d'air soit en contact avec la porte sur une distance la plus grande possible. La présence d'une plaque formant déflecteur entre les moyens d'entrée d'air 13 et les moyens de sortie d'air 14 peut en outre éviter un éventuel retour d'air directement des moyens d'entrée aux moyens de sortie d'air, notamment lorsque la vitesse d'entrée d'air est insuffisante.In addition, in the cavity, a baffle plate could be added, near the air inlet means 13. This plate can allow a better orientation of the air flow at the entrance to the door of the cavity so that the air flow is in contact with the door over as great a distance as possible. The presence of a baffle plate between the air inlet means 13 and the air outlet means 14 may furthermore prevent any return of air directly from the inlet means to the air outlet means. , especially when the air inlet speed is insufficient.
Par ailleurs, l'emplacement et la dimension des moyens d'entrée d'air 13 et des moyens de sortie d'air 14 peuvent être différents.Moreover, the location and the dimension of the air inlet means 13 and the air outlet means 14 may be different.
En particulier, les ouvertures prévues pour l'entrée d'air ou la sortie d'air peuvent ne pas s'étendre dans toute la largeur de la cavité.In particular, the openings provided for the air inlet or the air outlet may not extend throughout the width of the cavity.
