Abstract

The invention relates to a device for taking in fresh air, which device is placed in front of a fan, housed in a casing, of a heating or air-conditioning installation of a motor vehicle. Fresh air penetrates through a gap 10 existing between the windscreen 11 and the bonnet 12 of the vehicle and, after having undergone deflection and water and foreign-bodies separation, it passes into a filter 8, which can be replaced from above, and then into the fan 2; in order to preserve the ease of replacing the filter 8 and to prevent unintentional heating of the fresh air in the suction passage ending at the fan, the filter 8 is covered by a suction hood 14 which may be spaced apart and protected against heat coming from the bonnet 12. Application to the motor industry.

Description

La présente invention concerne un dispositif d'entrée d'air frais, qui est installé dans un véhicule automobile devant un ventilateur, logé dans un carter, d'une installation de chauffage ou de climatisation, l'air frais pénétrant dans un intervalle existant entre le pare-brise et le capot adjacent, en étant soumis en dessous de cet intervalle à une déviation et à une séparation d'eau et de corps étrangers pour être ensuite introduit dans un filtre, remplaçable par tirage vers le haut, et pénétrer ensuite du côté-aspiration dans le ventilateur. The present invention relates to a fresh air intake device, which is installed in a motor vehicle in front of a fan, housed in a casing, of a heating or air conditioning installation, the fresh air penetrating into an existing gap between the windshield and the adjacent hood, being subjected below this interval to a deflection and a separation of water and foreign bodies to be then introduced into a filter, replaceable by pulling upwards, and then penetrate the suction side in the fan.

Un dispositif d'entrée d'air frais de ce genre est connu d'après le brevet DE 33 30 951. Le trajet d'aspiration de l'air est long et suit un large passage en dessous du capot chauffé souvent par la chaleur dégagépar le moteur et/ou par le rayonnement solaire de sorte qu'il se produit, au moins pendant les mois d'été, un chauffage non intentionnel de l'air frais. A fresh air intake device of this kind is known from patent DE 33 30 951. The air suction path is long and follows a wide passage under the hood, often heated by the heat given off. the engine and / or by solar radiation so that, at least during the summer months, unintentional heating of the fresh air occurs.

L'invention a pour but, tout en conservant une facilité de remplacement du filtre, d'empêcher un chauffage non intentionnel de l'air frais dans le trajet d'aspiration. The object of the invention is, while retaining the ease of replacing the filter, to prevent unintentional heating of the fresh air in the suction path.

Ce problème est résolu en ce que le filtre est recouvert par une hotte d'aspiration pouvant être écartée et protégée contre la chaleur provenant du capot. This problem is solved in that the filter is covered by an extractor hood which can be removed and protected against heat from the cover.

En outre le côté supérieur de la hotte d'aspiration peut être thermiquement isolé par rapport au capot. In addition, the upper side of the extractor hood can be thermally insulated from the cover.

Pour accéder facilement au filtre, il est avantageux d'agencer la hotte d'aspiration de façon qu'elle puisse pivoter. For easy access to the filter, it is advantageous to arrange the extractor hood so that it can pivot.

On obtient une réduction additionnelle de place et de poids quand la hotte d'aspiration est constituée par des parties de la paroi capot.  An additional reduction in space and weight is obtained when the extractor hood consists of parts of the hood wall.

Egalement lorsque le capot a été enlevé par pivotement, on empêche une pénétration de corps étrangers et d'eau lorsqu'une partie de support recevant le filtre est recouverte par un couvercle pivotant articulé sur ladite partie. Also when the cover has been removed by pivoting, penetration of foreign bodies and water is prevented when a support part receiving the filter is covered by a pivoting cover hinged on said part.

D'autres caractéristiques et avantages de l'invention seront mis en évidence dans la su-ite de la description, donnée à titre d'exemple non limitatif, en référence aux dessins annexés dans lesquels la figure 1 représente une première forme de réalisation, avec une hotte d'aspiration fixée sur une partie de support, et la figure 2 représente un exemple de réalisation dans lequel la hotte d'aspiration est constituée par des zones du capot. Other characteristics and advantages of the invention will be highlighted in the su-ite of the description, given by way of nonlimiting example, with reference to the appended drawings in which FIG. 1 represents a first embodiment, with an extractor hood fixed on a support part, and FIG. 2 represents an exemplary embodiment in which the extractor hood is constituted by zones of the cover.

Sur la paroi frontale 1 d'une voiture de tourisme, non représentée en détail, il est prévu en plus d'un ventilateur 2 également un carter 3 entourant celui-ci, tandis que d'autres composants d'une installation de chauffa- ge ou de climatisation 4, représentée schématiquement, sont logés du côté de l'habitacle du véhicule. On the front wall 1 of a passenger car, not shown in detail, there is provided in addition to a fan 2 also a casing 3 surrounding it, while other components of a heating installation or air conditioning 4, shown schematically, are housed on the side of the passenger compartment of the vehicle.

Sur le côté supérieur du carter 3 est fixée par bride une partie de support 5 qui constitue un composant d'un dispositif d'entrée d'air frais 6. La partie de support 5 reçoit, en plus d'un clapet 7 agencé sous la forme d'un clapet d'air principal, également un filtre 8 pouvant être enlevé par le haut et elle est en outre pourvue d'un séparateur d'eau 9. On the upper side of the casing 3 is fixed by flange a support part 5 which constitutes a component of a fresh air intake device 6. The support part 5 receives, in addition to a valve 7 arranged under the in the form of a main air valve, also a filter 8 which can be removed from above and is further provided with a water separator 9.

L'air frais pénètre par un intervalle 10 existant entre le pare-brise 11 et un capot 12 en s'écoulant en direction de la partie de support 5, il est dévié et traverse une grille 13, qui fait partie d'une hotte d'aspiration 14 pouvant pivoter et recouvrant la partie de support 5. The fresh air enters through an interval 10 existing between the windshield 11 and a cover 12, flowing in the direction of the support part 5, it is deflected and passes through a grid 13, which is part of a hood d suction 14 which can pivot and cover the support part 5.

Dans ce processus de déviation, l'humidité entrainée et également des corps étrangers éventuellement entraînés sont séparés. De gros corps étrangers, comme par exemple des feuilles, sont alors retenus par une grille 15 placée audessus du séparateur d'eau 9, tandis que l'humidité séparée passe au travers de la grille 15 et parvient au séparateur d'eau 9 dont le bac est agencé un peu en forme de toit et comporte un orifice de décharge 16 au point le plus bas.In this deviation process, entrained moisture and also possibly entrained foreign bodies are separated. Large foreign bodies, such as leaves, are then retained by a grid 15 placed above the water separator 9, while the separated moisture passes through the grid 15 and reaches the water separator 9, the tray is arranged somewhat in the shape of a roof and has a discharge orifice 16 at the lowest point.

L'air pré-épuré de la manière décrite ci-dessus parvient - par l'intermédiaire de la hotte d'aspiration 14 - dans le filtre 8 où il subit une épuration fine, puis il passe par le clapet 7 plus ou moins largement ouvert et il arrive ensuite à l'orifice d'aspiration du ventilateur 2. The pre-purified air as described above arrives - via the suction hood 14 - in the filter 8 where it undergoes a fine purification, then it passes through the valve 7 more or less widely open and then it arrives at the suction port of the fan 2.

A cet égard, les deux exemples de réalisation ont une structure identique. Conformément à la figure 1, la hotte d'aspiration 14 est fixée de façon pivotante sur la partie de support 5 et la grille -13, pouvant être verrouillée par l'intermédiaire d'une fermeture 17 non représentée en détail, est reliée de façon articulée à la hotte d'aspiration 14 de sorte que, après que le capot 12 a été relevé par pivotement et après que la fermeture 17 a été desserrée, la hotte d'aspiration 14 peut être déplacée par pivotement en vue d'un remplacement du filtre 8.Pour que, lorsque la ventilation est enclenchée pendant des périodes chaudes de l'année, il ne se produist pas un chauffage inutile de l'air dans la zone de la hotte d'aspiration 14 par transmission de chaleur à partir du capot adjacent 12, il est prévu entre celui-ci et le côté supérieur 18 de la hotte d'aspiration 14 une couche d'isolation thermique 19. En addition ou à la place de cette couche 19, la hotte d'aspiration 14 peut être constituée d'un matériau thermiquement isolant. In this regard, the two exemplary embodiments have an identical structure. In accordance with FIG. 1, the suction hood 14 is pivotally fixed on the support part 5 and the grid -13, which can be locked by means of a closure 17 not shown in detail, is connected in a manner hinged to the extractor hood 14 so that, after the cover 12 has been raised by pivoting and after the closure 17 has been loosened, the extractor hood 14 can be moved by pivoting in order to replace the filter 8 so that, when the ventilation is switched on during hot periods of the year, unnecessary heating of the air in the area of the extractor hood 14 does not occur by heat transmission from the hood adjacent 12, there is provided between it and the upper side 18 of the suction hood 14 a layer of thermal insulation 19. In addition or in place of this layer 19, the suction hood 14 may be constituted of a thermally insulating material.

Dans l'exemple de réalisation de la figure 2, la hotte d'aspiration 14 est constituée par des zones 20 de la paroi du capot 12 et également la grille 13 constitue un composant fixe du capot 12, qui est pourvu, en dessous de son enveloppe en tôle 21, d'un corps profilé d'isolation 22. Ainsi, lors du pivotement du capot 12, également la hotte d'aspiration 14 est simultanément entrainée par pivotement. Pour que, lorsque le capot 12 est ouvert, le filtre 8 ne puisse être encrassé, celui-ci est recouvert par un couvercle pivotant 23 fixé sur la partie de support 5 et qui, quand le capot 12 est fermé, est transféré par un dispositif de commande 24 dans sa position d'ouverture alors que, quand le capot 12 est ouvert, il parvient sous l'effet de son poids propre ou bien par assistance d'un ressort, dans sa position de fermeture. représentée par des lignes en trait mixte.  In the embodiment of Figure 2, the suction hood 14 is formed by zones 20 of the wall of the cover 12 and also the grid 13 constitutes a fixed component of the cover 12, which is provided, below its sheet metal casing 21, of a profiled insulating body 22. Thus, during the pivoting of the cover 12, also the suction hood 14 is simultaneously driven by pivoting. So that, when the cover 12 is open, the filter 8 cannot be clogged, it is covered by a pivoting cover 23 fixed on the support part 5 and which, when the cover 12 is closed, is transferred by a device control 24 in its open position when, when the cover 12 is open, it arrives under the effect of its own weight or by assistance of a spring, in its closed position. represented by dashed lines.
