Definitions

  • This disclosure relates to a side defroster device.
  • Patent Document 1 discloses a side defroster device in which a frame-shaped bezel member with fins is attached to the air outlet of the instrument panel.
  • the vertical inner wall surface of the bezel member changes the direction of some of the air flow upward, suppressing the Coanda effect, in which the conditioned air blown out from the air outlet is attracted to the surface of the instrument panel.
  • At least one embodiment of the present invention aims to provide a side defroster device that can blow out a desired amount of conditioned air from an outlet toward a target set on the glass surface of the door glass.
  • a side defroster device is a side defroster device that includes an air outlet that opens on the upper surface of the instrument panel on the outer side in the vehicle width direction and blows conditioned air toward the side window of the vehicle, a side defroster duct that extends from an air conditioner to the air outlet within the instrument panel and supplies the conditioned air from the air conditioner to the air outlet, and a fin that is installed at the air outlet and guides the conditioned air in a predetermined direction, the fin is flat with its longitudinal direction extending in the vehicle width direction and has a flat surface on at least a part of its upper or lower surface, the side defroster duct has an outlet section that extends in the vehicle front-rear direction toward the air outlet and is connected to the air outlet, and the bottom wall surface of the outlet section has an outlet plane formed parallel to the plane of the fin near the air outlet.
  • the conditioned air flowing along the outlet plane is rectified along the plane of the fins arranged parallel to the outlet plane, and is blown out toward a target set on the glass surface of the door glass. This allows the desired flow rate of conditioned air to be blown out from the air outlet toward the target set on the glass surface of the door glass.
  • the bottom wall surface of the outlet portion is formed with a raised portion in the vicinity of the air outlet so as to approach the upper wall surface opposite the bottom wall surface as it approaches the air outlet, and the raised portion has the outlet plane provided at its top and a first inclined surface that inclines from the downstream end of the outlet plane in the blowing direction of the air conditioning air toward the air outlet in a direction away from the upper wall surface, and a ridgeline is formed between the outlet plane and the first inclined surface.
  • the conditioned air flowing along the outlet plane is separated at the ridge line and supplied to the fins. This makes it difficult for the air flowing along the outlet plane to be attracted to the first inclined surface, and the air flowing along the outlet plane can be smoothly supplied to the fins.
  • the fin is positioned so as to overlap the ridgeline of the downstream end of the outlet plane in the blowing direction when viewed from the blowing direction.
  • the fins hide the ridges when viewed from the blowing direction, creating continuity between the fins and the outlet plane, improving the appearance.
  • the raised portion has a second inclined surface that is inclined from the upstream end of the outlet plane in the blowing direction toward the upstream side of the outlet portion in the blowing direction, in a direction away from the upper wall surface.
  • the conditioned air flows along the second inclined surface, so the flow of the conditioned air gradually speeds up and is supplied to the outlet plane. This allows the air that flows along the second inclined surface to be smoothly supplied to the outlet plane.
  • the fin is inclined toward the rear and upward of the vehicle in a vertical cross-sectional view perpendicular to the longitudinal direction, and is inclined from the inside toward the outside in the vehicle width direction so as to be gradually positioned forward in the vehicle fore-and-aft direction in a top view.
  • the conditioned air supplied from the air conditioner to the air outlet passes through the fins and is rectified toward the target set on the glass surface of the door glass of the front side door. This allows the desired flow rate of conditioned air to be blown out from the air outlet toward the target set on the glass surface of the door glass of the front side door.
  • the air outlet opens into an inclined surface that gradually becomes lower in the vehicle height direction toward the rear of the instrument panel in the vehicle fore-and-aft direction, and the fins are inclined so as to gradually become higher in the vehicle height direction from the inside to the outside in the vehicle width direction when viewed from the rear.
  • the conditioned air supplied from the air conditioner to the air outlet passes through the fins and is rectified toward the target set on the glass surface of the door glass of the front side door. This allows the desired flow rate of conditioned air to be blown out from the air outlet toward the target set on the glass surface of the door glass of the front side door.
  • the fin has a pair of outer edges in the blowing direction of the conditioned air, and in a vertical cross-sectional view perpendicular to the longitudinal direction, the distance to a surface facing downward in the vehicle height direction based on a straight line connecting the pair of outer edges in the region from the center of the vehicle in the fore-and-aft direction to the front outer edge is less than the distance to a surface facing upward.
  • the path length of the surface facing downward in the vehicle height direction can be made shorter than the path length of the surface facing upward. This makes it possible to make the speed of air flowing along the surface facing downward in the vehicle height direction slower than the speed of air flowing along the surface facing upward in the region from the center of the vehicle in the fore-and-aft direction to the front outer edge.
  • the fin has a pair of outer edges in the direction in which the conditioned air is blown out, and in a vertical cross-sectional view perpendicular to the longitudinal direction, the distance from the center of the vehicle in the fore-and-aft direction to the rear outer edge to a surface facing downward in the vehicle height direction based on a straight line connecting the pair of outer edges is less than or equal to the distance to a surface facing upward.
  • the above configuration (8) allows the mold parting surface used when resin molding the fins to be positioned forward in the vehicle's fore-and-aft direction, improving the appearance of the fins.
  • the fin is curved such that the lower surface bulges downward in a vertical cross-sectional view perpendicular to the longitudinal direction.
  • the path length of the surface facing downward in the vehicle height direction is longer than the path length of the surface facing upward, so the air flows faster along the surface facing downward, and the air supplied to the fins can be blown out toward the upper side in the vehicle height direction.
  • a desired flow rate of conditioned air can be blown out of the air outlet toward a target set on the glass surface of the door glass.
