Abstract: A fan shroud includes a bell mouth portion and a rectangular portion. The bell mouth portion includes a circular wall that defines a discharge port and accommodates a propeller fan. The rectangular portion defines a suction port and includes a close wall close to the circular wall, and a farther wall farther from the circular wall than the close wall is from. The close wall includes a closest portion closest to the circular wall in the close wall, and a pair of connection portions connected to the farther wall. The closest wall is between the pair of connection portions. The fan shroud includes an opening portion extending through the rectangular portion from inside to outside of the rectangular portion. At least one of the pair of connection portions includes the opening portion, and the closest portion does not include the opening portion.

Abstract: A fan shroud, in which air flows from a suction port to an outlet port, includes: a bell mouth part having a circular wall, the outlet port being formed by the bell mouth part; and a rectangle part having a proximity wall located adjacent to the circular wall and a distal wall distant from the circular wall than the proximity wall, the suction port being formed by the rectangle part. The proximity wall has a most close area that is most close to the circular wall. The circular wall has an extended wall part extended in an axial direction of a propeller fan than a residual portion of the circular wall. The extended wall part is provided along a rotational direction of the propeller fan from a position opposing the most close area.

Abstract: A blower fan includes a plurality of blades radially extending from a boss provided at a rotary center and spaced apart from each other in the rotational direction, and a ring portion connecting outer peripheral ends of the blades in a ring shape. A radially outer end part at an end on an air-flow upstream side of the ring portion is positioned outward in a radial direction of a rotary shaft in the blower fan, as toward the air-flow upstream side. Thus, the blower can prevent the backflow air from being swirled, thereby reducing noise.

Abstract: A blower fan includes a plurality of blades radially extending from a boss provided at the rotary center and spaced apart from each other in the rotational direction, and a ring portion connecting outer peripheral ends of the blades in a ring shape. An inner peripheral wall surface of an end part on an air-flow downstream side of a cylindrical portion is disposed on the outside in a radial direction of the rotary shaft in the blower fan, with respect to an end part on the air-flow downstream side of the ring portion. The end part on the air-flow downstream side of the cylindrical portion is positioned outward in the radial direction of the rotary shaft, as toward the air-flow downstream side. Thus, the blower can prevent the backflow air from being swirled, thereby reducing noise.

Abstract: An air expandable bladder grips a beverage container within the vehicle and serves as a beverage holder. The container holder utilizes a hot air duct that receives its hot air from the heater core and its cold air from the evaporator, both of which may be located within the HVAC case. An air inlet duct receives the hot, cold, or blended air from an air mixing valve and directs the air into, and expands, the bladder. An exit orifice may exist in the bladder to release air from the bladder and provide back pressure in the bladder. A user-controlled switch permits a person to select whether hot, cold, or blended air will pass into the bladder inlet duct. The drink holder may be located within a center console, dash, door or other location within the vehicle interior.
