Definitions

  • the present invention relates to an arrangement for preventing mist and ice formation on a side window in a door of a motor vehicle, to which window is connected at least one air-supply duct with an outlet located at the bottom part of the window, via which duct and outlet air is fed from a fan arranged in the vehicle.
  • the present invention relates to a simple arrangement for achieving mist- and ice-free windows in a vehicle, especially the rear side-windows of a conventional passenger car.
  • the present invention is characterized in that the fan is arranged in the door side below the window between an outer bodywork panel of the door and an inner inside-wall panel of the door and in that the fan draws air through an inlet duct, the inlet of which is located in the inside-wall panel towards the vehicle interior.
  • the invention is furthermore characterized in that the fan, the outlet duct and the inlet duct constitute a single unit.
  • the positioning of the fan in the door side below the window and the integration of the fan and the duct parts into one unit result in considerable advantages.
  • the unit can be easily and quickly installed in the vehicle and located favourably, from the point of view of noise, inside a sound absorbing inner panel, while also improving the opportunities for keeping the side windows of the vehicle free of mist and ice.
  • the unit is mounted in a rear door of the vehicle, wherein the invention is characterized in that the fan and the outlet duct are arranged in the front part of the door with the air outlet arranged at the bottom front part of the window and in that the outlet is provided with air-directing surfaces which guide the air from the outlet obliquely upwards, backwards and inwards towards the window.
  • FIG. 1 illustrates schematically an arrangement according to the invention in a rear door of a motor vehicle
  • FIG. 2 illustrates schematically the arrangement according to the invention essentially according to a cross-section A--A in FIG. 1,
  • FIG. 3 shows an advantageous embodiment of the air outlet of the arrangement according to the invention viewed from above and
  • FIGS. 4a, 4b show outlets essentially according to section B--B and section C--C in FIG. 3.
  • FIG. 1 shows a rear door 1 located directly behind the centre pillar 2 in a conventional passenger car.
  • Door 1 has a window 4 which opens and closes vertically and a fixed window 5 together with an inner panel 6, facing towards the vehicle interior, and made of moulded wood fibre material.
  • the panel is fixed to door 1 which is otherwise made of sheet metal.
  • FIG. 2 shows schematically how door 1 comprises an outer sheet metal panel 7 and an inner reinforcing sheet-metal structure 8 welded thereto, to which is secured, in addition to inner panel 6, a door handle 9 and (not shown) arrangements for a door lock and a window regulator crank.
  • Ventilation unit 10 is secured to the said inner panel 6 in a location in the front part of the door.
  • Ventilation unit 10 consists of an integral unit comprising inlet duct 11, fan 12 and outlet duct 13.
  • Outlet duct 13 has an outlet close to the front part of bottom edge 14 of window 4, while inlet duct 11 has an inlet in the bottom part of the door.
  • the run of the said ducts is adapted to the design of inner door panel 6.
  • Inner panel 6 is in fact designed with atop and a bottom part, 15 and 16, pressured in towards the outside of door 1, of which parts the top contains the handle 9 and locking mechanism (not shown) while the bottom forms a storage pocket 17 together with a wall element 18 located inside and facing towards the interior.
  • the said top and bottom parts 15 and 16 are surrounded by beam-like projections in inner panel 6 which face towards the interior.
  • the shape of ventilation unit 10 is matched to the said projections 19, for which reason it receives a well-protected location also in terms of the sound insulation of ventilation unit 10 relative to the interior.
  • Ventilation unit 10 consists of two housing halves 21 and 22 formed of plastic material with an essentially vertical joint face which essentially runs in or parallel to the longitudinal plane of symmetry of ducts 11, 13. Housing halves 21, 22 are attached to each other by means of snap elements (not shown) and thus also accommodate fan 12, which consists of electric motor 20 which drives impeller 23. Motor 20 is elastically mounted in rubber support 24 which in turn rests against a surrounding bearing housing 25 formed in the one housing half 21. Via cable 26 the motor obtains the necessary electrical energy from a controllable electric circuit (not shown).
  • Nozzles 28, 30 constitute separate parts which, with outer edges 29 and 31, rest against the surface of inner panel 6 that faces towards the interior, at the same time as they are connected to the outlet and inlet respectively of ducts 11, 13 by means of snap and/or separate fasteners 32.
  • Outlet duct 13 together with the nozzle 30 provides the discharge air with a direction which is obliquely inwards towards rear side-window 4.
  • the latter is, in a manner customary in modern cars, slightly curved and angled in such a way that its upper part is located closer to the centre of the vehicle than it lower part. This means that the direction of discharge of the air is generally almost vertical or even - as shown in FIG. 2--at a slight angle inwards towards the interior.
  • Outlet nozzle 30 shown in FIGS. 3, 4a and 4b guides the discharge air through three nozzles 34, 35 and 36, separated from each other, of which two 34, 36 are separated from the third 35 by a longitudinal central wall 37.
  • the said two nozzles 34, 36 are situated further from window 4 than the third nozzle 35 and they moreover located in the longitudinal direction on both sides of the third nozzle 35, viewed towards the front of the vehicle.
  • the first and second nozzles 34, 35 each have a central guide plate 38 and 39 respectively, which, together with connected envelope surfaces 41 and 42 respectively from the corresponding design of outlet duct 13 in the respective ventilation housing half 21, 22, gives the discharge air a predetermined direction.
  • First nozzle 34 thus gives the air a direction corresponding to arrow a in FIG. 1 and has a smaller angle relative to the horizontal plane than second nozzle 35.
  • the direction of air flow from the said second nozzle 35 is shown by arrow b in FIG. 1.
  • the third nozzle 36 consists of an essentially vertical hole which gives the exhaust air a corresponding vertical direction corresponding to arrow c in FIG. 1.
  • the design of outlet nozzle 30 thus provides several separate air streams which, without disturbing each other to any great extent, flow over the whole window 4. By this means, a completely mist-free window is achieved in a relatively short time, starting at a central front part at eye-level of the back seat passenger
  • inlet 28 of ventilation unit 10 is advantageously located in such a way as to capture an air stream (arrow d) from the ventilation air ducts which, in passenger cars, usually discharge under the front seats.
  • the said air stream d originates from the regular ventilation system (not shown here) of the vehicle and supplies, when required, heated air to the footwells for the back seat passengers.
  • the ventilation unit according to the invention can consequently capture the heated air and convey it further at increased pressure to the rear side-window, which consequently increases the possibility of quickly achieving good visibility through the latter.
  • the possibility be excluded here of incorporating separate electrical heating in ventilation unit 10.
  • the electrical control of fan 12 of ventilation unit 10 can expediently be carried out at the same time as the control of the fan of the regular ventilation system. It can also follow switching of an electric heating arrangement for the rear window of the vehicle and/or a separate switch on the corresponding door. It is also possible to control the fan by a sensor which senses the presence of mist.
  • the exemplary embodiment described should not thus be regarded as limiting the present invention, but rather it can be modified in a number of embodiments within the scope of the patent claims which follow.
