Definitions

  • the invention relates to a ventilation device for a vehicle with at least one fan-nozzle unit with an air outflow opening directed into a vehicle interior.
  • the invention also relates to a vehicle with such a ventilation device.
  • the air curtain system of the air conditioning system forms an air curtain between a seat in a first row and a seat in a second row using air expelled in the area of an instrument panel of the vehicle.
  • the air curtain system comprises a fan, a fan housing and a ventilation duct.
  • the fan is arranged on a vehicle ceiling so that the air can flow from the front to the rear of the instrument panel.
  • the fan housing covers the fan to expel the air through one side of the fan housing.
  • the ventilation duct is connected to the fan housing and installed in the width direction of the vehicle ceiling in order to direct the air of the fan from the vehicle ceiling to the floor of the vehicle compartment.
  • US 2430 335 A shows a ventilation device for a vehicle. This has an outflow opening in the upper area of the backrest of a vehicle seat, which is opposite a reflector on the opposite side on the vehicle roof, which ensures targeted guidance of the air flowing out of the opening.
  • US Pat. No. 2,336,089 A discloses an outflow opening in the seat back of a vehicle which conveys air in the direction of the vehicle roof. From there, the air flows in two circular air currents either through the rear or along the front of the cockpit and back to the lower edge of the seat. The division into the two air currents is done by an element on the opening.
  • DE 102016 117443 A1 shows a vehicle seat with a ventilation device, which consists of a forward air duct system with air outlets for blowing out air forwards through the seat surface intended for a seat occupant and a rear air duct system with at least one air outlet for blowing out air backwards.
  • a vehicle seat is known from DE 102007002 001 A1 which has a ventilation device which is provided for ventilating the rear of the vehicle and for this purpose has a fan and an air outlet opening.
  • the invention is based on the object of specifying a ventilation device for a vehicle that is improved over the prior art and a vehicle with such a ventilation device.
  • the object is achieved according to the invention by a ventilation device which has the features specified in claim 1 and by a vehicle which has the features specified in claim 5.
  • a ventilation device for a vehicle has at least one fan nozzle unit with an air outflow opening directed into a vehicle interior.
  • the air outflow opening is in a section of a backrest head, d. H. arranged in an upper area, a seat back of a vehicle seat.
  • the fan-nozzle unit is designed to generate an air curtain for separating at least one area of the vehicle interior from at least one further area and / or for supplying conditioned air into the further area.
  • the fan-nozzle unit comprises at least one broadband nozzle and at least one individual nozzle.
  • the at least one broadband nozzle is used for generation of the air curtain, whereas the at least one individual nozzle is provided for supplying air into the wider area of the vehicle interior.
  • the ventilation device as part of a vehicle air conditioning system, an optimized use of air flowing out of the air outlet opening in the vehicle interior is possible.
  • an air flow flowing out of an air outlet opening of an instrument panel of the vehicle is directed by means of the air curtain in such a way that no conditioned air from the area reaches the further area when the air curtain is in place.
  • the consumption of electrical energy for ventilation, in particular for air-conditioned ventilation, of the vehicle interior can be reduced by means of the ventilation device, so that a range of available electrical energy can be increased.
  • the overall energy requirement of the vehicle can be reduced by means of the ventilation device, as a result of which the frequency for charging the electrical energy store can be reduced, so that electricity costs can likewise be reduced.
  • a fan of the fan-nozzle unit is designed in one possible embodiment as a radial fan or roller fan, so that the fan-nozzle unit can be made relatively compact and thus requires a comparatively small installation space for its arrangement.
  • the fan-nozzle unit is arranged in the vehicle seat, in particular in the area of the backrest head, so that a distance between the fan-nozzle unit and the air outlet opening is relatively short. Because the fan-nozzle unit is integrated in the vehicle seat, a division of the areas which can be referred to as air conditioning zones can be carried out in a meaningful way, particularly when the adjustment range of the vehicle seat is increased in the longitudinal direction of the vehicle.
  • At least one further fan / nozzle unit in the area of a beltline of at least one vehicle door of the vehicle is arranged.
  • an air curtain can be formed between an occupant and a comparatively cold vehicle window, so that the occupant is separated from the vehicle window.
  • the invention also relates to a vehicle with a ventilation device, the ventilation device being provided both for generating an air curtain for separating at least one area of the vehicle interior from at least one further area and for supplying conditioned air into the further area of the vehicle interior.
  • FIG. 1 schematically shows a vehicle interior with two occupants.
  • the single figure shows a vehicle interior 1 in which an occupant 2, in particular a vehicle user, is seated on a vehicle seat 3 in a front area B1 of the vehicle 4 and another occupant 5 is seated in a further area B2, i.e. in a rear area, of the vehicle 4 .
  • the vehicle 4 is an electric car which is operated by means of electrical energy, air conditioning of the vehicle interior 1 and the occupants 2, 5 being relatively energy-intensive.
  • a ventilation device B described below is provided.
  • the ventilation device B comprises a fan-nozzle unit 6, wherein a fan of this can be designed as a radial fan or as a roller fan.
  • the fan-nozzle unit 6 is arranged in a backrest head of a seat back 3.1 of the vehicle seat 3 on which the occupant 2 is seated.
  • a backrest head is to be understood in particular as an upper section of the seat back 3.1.
  • the air outflow opening is arranged on an upper side of the seat back 3.1, with the fact that the fan-nozzle unit 6 is integrated in the vehicle seat 3, this is carried along in the longitudinal direction of the vehicle when a position of the vehicle seat 3 is adjusted.
  • the fan nozzle unit 6 comprises at least one broadband nozzle and at least one individual nozzle, with the broadband nozzle being able to shape an air stream in such a way that it flows as an air curtain L out of the air outlet opening of the fan nozzle unit 6.
  • This generated air curtain L extends essentially perpendicularly from the top of the seat back 3.1 to the vehicle roof 4.1, so that the front area B1 is separated from the further area B2.
  • a narrowly delimited air jet with a comparatively high flow velocity can be generated by means of the broadband nozzle, which results in the separation of the areas B1, B2.
  • An air-conditioned air flow L1 which flows out of an air outflow opening arranged in an instrument panel 7, is deflected when the air curtain L is generated in such a way that the conditioned air flow L1 flows from the front area B1 into the further area B2.
  • the fan-nozzle unit 6 thus has two settings, the air curtain L being generated by means of a first setting and conditioned air L2 being supplied to the further occupant 5 by means of the fan-nozzle unit 6 by means of a second setting.
  • a third setting is also conceivable, by means of which the air curtain L can be generated and conditioned air L2 is simultaneously supplied to the further occupant 5, as shown in the figure.
  • conditioned air L2 can be supplied to the further occupant 5 in the further area B2 of the vehicle interior 1 by means of the fan nozzle unit 6 integrated in the vehicle seat 3 means that a rear air vent integrated in a center console and assigned to the further area B2 can be omitted.
  • At least one further fan-nozzle unit 6 is arranged in a section of a so-called beltline 8 of the vehicle 4, so that a further air curtain L emerges from the beltline 8.
  • the occupant 2 can be separated from a comparatively cold vehicle window, in particular a side window.
  • a fan / nozzle unit 6 is arranged in a vehicle 4 designed as an off-road sedan or station wagon in such a way that a loading area is separated from an occupant area of such a vehicle 4.
