The conditioner has a chamber (1) for heating and mixing air in the passenger compartment. It is supported under a hollow cross air inlet beam (2) and a hollow distributor beam. A driven fan (7) at the chamber entry blows air towards a heat exchanger and a mixer valve. These make a mixing chamber (9) with outlets for demisting and defrosting windows and the passenger compartment. There is also an auxiliary compartment (12) for feeding fresh air. There are three air outlets (16,17,19) worked by regulating valves (26,27).

Description

La présente invention, due à la collaboration deMM. Richard UCHTO, se rapporte à un dispositif de chauffage et d'aération pour véhicule automobile et en particulier à un bottier de chauffage à mixage d'air.The present invention, due to the collaboration ofMM. Richard UCHTO, relates to a heating and aeration device for a motor vehicle and in particular to an air mixing heating boot.

Dans la demande de brevet français déposée sous le numéro 78/27 998 par le présent demandeur, on a déjà décrit un dispositif de chauffage compact à mixage d'air disposé dans l'habitacle du véhicule sous une poutre creuse transversale d'admission d'air extérieure et une autre poutre creuse transversale adjacente de répartition d'air. Un compartiment principal assure la distribution de l'air mixé vers le pare-brise et éventuellement vers les vitres latérales du véhicule pour le dégivrage/désembuage et vers le plancher pour le chauffage proprement dit, au moyen de deux conduits de sortie donnant dans la chambre de mixage du compartiment principal.Un compartiment auxiliaire court-circuite l'échangeur de chaleur situé dans le compartiment principal et distribue de l'air frais vers des aérateurs disposés notamment à l'avant de l'habitacle, sur la planche de bord, par l'intermédiaire de la poutre de répartition. Un groupe motoventilateur envoie de l'air pulsé vers les compartiments principal et auxiliaire.In the French patent application filed under number 78/27 998 by the present applicant, a compact air mixing heating device has already been described, placed in the passenger compartment of the vehicle under a hollow transverse intake beam. outside air and another adjacent transverse hollow beam for air distribution. A main compartment distributes the mixed air to the windshield and possibly to the side windows of the vehicle for defrosting / demisting and to the floor for the actual heating, by means of two outlet ducts leading into the room mixing compartment in the main compartment. An auxiliary compartment short-circuits the heat exchanger located in the main compartment and distributes fresh air to aerators arranged in particular at the front of the passenger compartment, on the dashboard, by through the distribution beam. A fan unit sends forced air to the main and auxiliary compartments.

La présente invention propose une modification du bottier de chauffage et du circuit de distribution permettant de faire une distinction entre l'alimentation en air chaud du pare-brise et l'alimentation des aérateurs latéraux pour le dégivrage/désembuage des vitres latérales dans le but d'augmenter encore les possibilités de réglage et de confort.The present invention proposes a modification of the heating boot and of the distribution circuit making it possible to distinguish between the supply of hot air to the windshield and the supply of the side vents for defrosting / demisting the side windows for the purpose of '' further increase the possibilities of adjustment and comfort.

A cet effet, le bottier compact comporte trois sortes de sorties distinctes donnant dans la chambre de mixage et destinées à alimenter respectivement la base du pare-brise par l'intermédiaire de la poutre de répartition, les aérateurs latéraux à buses orientables par l'intermédiaire de conduits souples ou semi-rigides et le plancher du véhicule ou partie inférieure de l'habitacle. Chaque sortie peut être obturée indépendamment par son propre volet de réglage de débit, les volets pouvant éventuellement être couplés mécaniquement et manoeuvrés simul tanément ou avec un certain décalage par une commande unique au tableau de bord.For this purpose, the compact shoemaker has three different kinds of outlets giving into the mixing chamber and intended respectively to feed the base of the windshield via the distribution beam, the side aerators with nozzles orientable through flexible or semi-rigid conduits and the vehicle floor or lower part of the passenger compartment. Each outlet can be closed independently by its own flow adjustment flap, the flaps possibly being able to be mechanically coupled and operated simultaneously or with a certain offset by a single command on the dashboard.

Le dispositif selon l'invention permet d'augmenter l'efficacité du dégivrage et du désembuage en particulier des vitres latérales, tout en conservant la possibilité de ventiler en air frais extérieur, dyna mique ou pulsé, le conducteur et le passager par le ou les aérateurs centraux alimentés par le compartiment auxiliaire indépendant de la chambre de mixage.The device according to the invention makes it possible to increase the efficiency of defrosting and demisting, in particular of the side windows, while retaining the possibility of ventilating the outside and dynamic or pulsed air, the driver and the passenger by the central aerators supplied by the auxiliary compartment independent of the mixing chamber.

La description qui suit fait référence au dessin annexé sur lequel - la figure 1 est une vue en élévation de l'ensemble du dispositif, prise de l'intérieur du véhicule selon la flèche I de la figure 4, - les figures 2, 3 et 4 illustrent en coupe, selon la ligne II de la figure 1, le fonctionnement du dispositif respectivement en ventilation, en mixage et en chauffage.The following description refers to the attached drawing in which - Figure 1 is an elevational view of the entire device, taken from inside the vehicle according to arrow I in Figure 4, - Figures 2, 3 and 4 illustrate in section, along line II of Figure 1, the operation of the device respectively in ventilation, mixing and heating.

On reconnait,sur les figures 1 et 2, un bottier 1 de chauffage et d'aération compact, disposé sensiblement au milieu et à l'avant de l'habitacle du véhicule, à cheval sous une poutre creuse transversale 2 d'admission d'air extérieur, bordée à l'avant par le tablier 3 et une autre poutre transversale 4 adjacente longeant le bord inférieur du pare-brise 5 et dont la paroi arrière (sens du véhicule) forme la planche de bord 6.We recognize, in FIGS. 1 and 2, a compact heating and ventilation case 1, arranged substantially in the middle and at the front of the passenger compartment of the vehicle, astride a transverse hollow beam 2 of intake outside air, bordered at the front by the apron 3 and another adjacent transverse beam 4 running along the lower edge of the windshield 5 and whose rear wall (direction of the vehicle) forms the dashboard 6.

Le bottier dé chauffage est du type à mixage d'air à circulation dynamique ou pulsée par un groupe motoventilateur 7 disposé à la sortie de la poutre d'admission 2 et à l'entrée dtun compartiment principal 8 occupé par la chambre de mixage 9 et par un échangeur de chaleur 10 obturable par un volet de mixage classique 11 de manière à court-circuiter complètement ltéchangeur de chaleur, si besoin est.The heating boot is of the air mixing type with dynamic or pulsed circulation by a fan unit 7 disposed at the outlet of the intake beam 2 and at the inlet of a main compartment 8 occupied by the mixing chamber 9 and by a heat exchanger 10 closable by a conventional mixing flap 11 so as to completely short-circuit the heat exchanger, if necessary.

Par ailleurs, le groupe motoventilateur 7 souffle parallèlement dans un compartiment auxiliaire 12 contigu, débouchant directement sur les grilles orientables d'un aérateur central 13 disposé à l'arrière du bottier 1. Comme on le comprend, cet aérateur apporte de l'air frais de ventilation aux occupants du véhicule, indépendamment du circuit de chauffage du bottier. Un volet 14 permet d'en régler le débit d'air.Furthermore, the fan unit 7 blows in parallel in an adjoining auxiliary compartment 12, leading directly to the orientable grids of a central aerator 13 disposed at the rear of the boot 1. As is understood, this aerator provides fresh air ventilation to the occupants of the vehicle, independently of the boot heater circuit. A flap 14 allows the air flow to be adjusted.

De façon classique, la chambre de mixage 9 comporte (figure 1) des sorties distribuant l'air mixé soit vers le bas de l'habitacle, à l'avant 15, 16 et à l'arrière 17, pour le chauffage par les pieds, soit vers le bas du pare-brise 5 pour le dégivrage/désembuage de ce dernier.Conventionally, the mixing chamber 9 comprises (FIG. 1) outlets distributing the mixed air either towards the bottom of the passenger compartment, at the front 15, 16 and at the rear 17, for heating by the feet. or down the windshield 5 for defrosting / demisting the latter.

Conformément à 11 invention, outre les sorties prévues vers l'habitacle et vers le pare-brise, la chambre de mixage 9 comporte d'autres sorties 18, 19 prévues pour distribuer l'air mixé vers les aérateurs latéraux 20, 21 montés respectivement à gauche et à droite de la planche de bord 6,
proximité des vitres latérales. Pour cela, les sorties latérales du bottier de chauffage sont reliées aux aérateurs par l'intermédiaire des conduits souples ou semi-rigides, représentés schématiquement par les traits mixtes22 23 de la figure 1. De préférence, chaque aérateur latéral possède son propre volet de réglage de débit ainsi qu'un cadre orientable connu en soi.In accordance with the invention, in addition to the outlets provided to the passenger compartment and to the windshield, the mixing chamber 9 has other outlets 18, 19 provided for distributing the mixed air to the side aerators 20, 21 mounted respectively at left and right of the dashboard 6,
near the side windows. For this, the lateral outlets of the heating boot are connected to the aerators via flexible or semi-rigid conduits, represented schematically by the dashed lines 22 23 in FIG. 1. Preferably, each lateral aerator has its own adjustment flap as well as a steerable frame known per se.

Par ailleurs, le conduit de sortie 24 affecté exclusivement au dégi vrageldésembuage du pare-brise débouche directement du bottier vers la poutre creuse 4 qui répartit l'air mixé vers les orifices 25 situés à la base du pare-brise.Furthermore, the outlet conduit 24 assigned exclusively to the degrapped defogging of the windshield opens directly from the case to the hollow beam 4 which distributes the mixed air towards the orifices 25 located at the base of the windshield.

Deux volets de réglage 26, 27, de type papillon par exemple, règlent les débits d'air mixé respectivement vers l'habitacle et le pare-brise. De préférence, ces volets sont couplés mécaniquement et commandés en séquence de façon connue, à partir d'une commande manuelle unique située au tableau de bord, par exemple au moyen d'un levier de réglage à effort constant.Two adjustment flaps 26, 27, of the butterfly type for example, regulate the mixed air flows to the passenger compartment and the windshield respectively. Preferably, these flaps are mechanically coupled and controlled in sequence in a known manner, from a single manual control located on the dashboard, for example by means of an adjustment lever with constant force.

Le dispositif permet de réaliser les fonctions de climatisation suivantes
En ventilation maximale, figure 2, l'air frais alimente simultanément les compartiments principal 8 et auxiliaire 12 du boitier. L'échangeur de chaleur 10 est court-circuité par le volet de mixage 11, ce qui permet d'éviter les pertes de charges à travers l'échangeur et d'obtenir un dépit d'air maximal aux aérateurs latéraux 20, 21 et centraux 13.The device makes it possible to perform the following air conditioning functions
In maximum ventilation, FIG. 2, the fresh air simultaneously feeds the main 8 and auxiliary 12 compartments of the case. The heat exchanger 10 is short-circuited by the mixing flap 11, which makes it possible to avoid pressure drops through the exchanger and to obtain maximum air spite at the lateral aerators 20, 21 and central 13.

En position mixage, figure 3, l'air mixé dans une proportion dépendant du réglage du volet 11 est distribué à volonté vers les diverses sorties concentrées dans la chambre de mixage 9 du bottier et son débit est réglé par les volets 26, 27.-L'alimentation des aérateurs latéraux, orientés vers les vitres latérales permet de lutter contre l'effet de parois froides et de maintenir notamment le désembuage des vitres. En même temps, les aérateurs centraux permettent d'obtenir une agréable ventilation d'air frais, vers les occupants du véhicule.In the mixing position, Figure 3, the air mixed in a proportion depending on the setting of the flap 11 is distributed at will to the various outputs concentrated in the mixing chamber 9 of the shoemaker and its flow rate is regulated by the flaps 26, 27.- The supply of side vents, oriented towards the side windows helps to combat the effect of cold walls and in particular to maintain the demisting of the windows. At the same time, the central air vents provide pleasant ventilation of fresh air to the occupants of the vehicle.

En position de chauffage maximal, figure 4, les aérateurs latéraux 20, 21 permettent de lutter efficacement contre le givrage des vitres latérales, par temps froid, ou contre leur embuage par temps humide, tout en conservant la possibilité d'aération en air frais par les aérateurs centraux, comme dans le cas précédent. En outre, il est possible d'orienter les aérateurs latéraux préalablement vers les occupants pour leur donner une impression favorable de rapidité de chauffage de l'habitacle et de puissance du dispositif de chauffage. In the maximum heating position, FIG. 4, the side aerators 20, 21 make it possible to fight effectively against the icing of the side windows, in cold weather, or against their fogging in wet weather, while retaining the possibility of aeration in fresh air by central air vents, as in the previous case. In addition, it is possible to orient the side aerators beforehand to the occupants to give them a favorable impression of speed of heating of the passenger compartment and power of the heating device.
