Abstract
In a vehicular air conditioning apparatus, a pair of covers are provided on the respective sides of the casing that is constituted by respective air passages. The covers rotatably support a pivot shaft for a defroster damper and a pivot shaft for a sub-defroster damper. The sub-defroster damper is disposed in a passage directly connecting the heater core with the defroster blow-out port, and is disposed on an upstream side of the defroster damper. First and second blower units supply air into the casing. The sub-defroster damper is disposed so as to face a passage which is disposed even inside the casing. Thus, the flowing direction and the amount of air is adjusted.
Claims19
A vehicular air conditioning apparatus including a first blower unit, a second blower unit, a casing in which passages are formed, air from the first and second blower units passing the passages, an evaporator and a heater core disposed inside the casing, wherein the casing comprises:
- a defroster blow-out port that opens at an upper center portion of the casing;
- a vent blow-out port at the upper portion of the casing;
- openings provided on respective sides of the casing;
- cover members covering the openings;
- an air mixing damper;
- a temperature control damper;
- and
- a vent damper,
- wherein the cover members rotatably support a defroster damper and a sub-defroster damper that open/close the defroster blow-out port,
- the sub-defroster damper is disposed immediately above the heater core and the defroster damper is disposed immediately above the sub-defroster damper such that the sub-defroster damper and the defroster damper form a first air passage and air from the heater core is supplied linearly straight up to the defroster blow-out port through the first air passage,
- the air mixing damper is disposed above the evaporator, the temperature control damper is disposed above the air mixing damper, and the vent damper is disposed above the temperature control damper such that the air mixing damper, the temperature control damper, and the vent damper form a second air passage and air from the evaporator is supplied linearly straight up to the vent blow-out port through the second air passage, and
- the temperature control damper is disposed between the first air passage and the second air passage such that when the temperature control damper closes, the air from the heater core does not enter into the second air passage and when the temperature control damper opens, the air from the heater core enters into the second air passage.
A vehicular air conditioning apparatus including a casing, an evaporator and a heater core disposed inside the casing, wherein the casing comprises:
- a blow-out port that opens at an upper center portion of the casing;
- openings provided on respective sides of the casing;
- and
- cover members covering the openings,
- wherein the cover members rotatably support a first damper and a second damper that open/close the blow-out port,
- the second damper is disposed immediately above the heater core and the first damper is disposed immediately above the second damper such that air from the heater core is supplied linearly straight up to the blow-out port through the second damper and the first damper,
- the evaporator has a lower surface and an upper surface, the evaporator cooling air by passing air from the lower surface to the upper surface,
- the heater core has a lower surface and an upper surface, the heater core heating air by passing air from the lower surface to the upper surface,
- the cover members cover the openings and support pivot axes of the second damper and the first damper such that directions of the pivot axes of the second damper and the first damper are in parallel with the lower and upper surfaces of the heater core and the lower and upper surfaces of the evaporator,
- the vehicular air conditioning apparatus further comprises a first intake port that attaches a first blower to the casing and a second intake port that attaches a second blower to the casing,
- the casing further comprises a rear passage connected to a downstream side of the heater core, the rear passage supplying air from the heater core to rear-side seats in the vehicle, and
- the rear passage is branched in a forked manner such that the branched rear passages surround the second intake port.
