Abstract
A vehicle air conditioner has an air conditioning unit. The unit has a blower unit and an heat exchanger. The unit has a defroster outlet opening and an outside air inlet opening. The unit also has a switching door. The unit has a first passage between the defroster opening and an upstream side of the blower unit, and a second passage between the defroster outlet opening and a downstream side of the heat exchanger. During an inside air suction mode, the outside air inlet opening is closed, and the first passage is opened and the second passage is closed by the switching door. Thus, inside air is sucked through the defroster outlet opening during the inside air suction mode.
Claims11
A vehicle air conditioner comprising:
- a blower unit that blows air toward a passenger compartment;
- a heat exchanger that exchanges heat with the air blown by the blower unit;
- a first outlet through which the air passed through the heat exchanger is blown toward a first space of the passenger compartment;
- a second outlet through which the air passed through the heat exchanger is blown toward a second space of the passenger compartment;
- an outside air inlet from which outside air is sucked into an upstream side of the blower unit;
- and
- changing means for changing a connection of the second outlet to one of the upstream side of the blower unit and a downstream side of the heat exchanger;
- wherein:
- the blower unit and the heat exchanger are disposed adjacent to each other to be a single assembled component,
- the outside air inlet is closed and the changing means connects between the second outlet and the upstream side of the blower unit and disconnects between the second outlet and the downstream side of the heat exchanger during an inside air suction mode where inside air is sucked into the upstream side of the blower unit, and
- the outside air inlet is opened and the changing means connects between the second outlet and the downstream side of the heat exchanger and disconnects between the second outlet and the upstream side of the blower unit during an outside air suction mode where the outside air is sucked into the upstream side of the blower unit.

A vehicle air conditioner comprising:
- a housing that air blowing toward a passenger compartment flows in;
- a heat exchanger that exchanges heat with the air so that the air becomes conditioned air;
- and
- a blower unit that blows the air toward the passenger compartment through the heat exchanger, wherein:
- the heat exchanger and the blower unit are disposed adjacent to each other as a single assembled component in the housing;
- the housing includes:
- a first outlet opening through which the conditioned air is blown toward a first space of the passenger compartment,
- a second outlet opening through which the conditioned air is blown toward a second space of the passenger compartment,
- an outside air inlet opening from which outside air is sucked into an upstream side of the blower unit, and
- change means for changing a connection of the second outlet opening to one of the upstream side of the blower unit and a downstream side of the heat exchanger;
- the outside air inlet opening is closed and the change means connects between the second outlet opening to the upstream side of the blower unit and disconnects between the second outlet opening and the downstream side of the heat exchanger during an inside air suction mode where inside air is sucked into the upstream side of the blower unit;
- and
- the outside air inlet opening is opened and the change means connects between the second outlet opening to the downstream side of the heat exchanger and disconnects between the second outlet opening and the upstream side of the blower unit during an outside air suction mode where the outside air is sucked into the upstream side of the blower unit.
10 more elements
A vehicle air conditioner comprising:
- a housing;
- a partition that divides the housing into a first room and a second room;
- a blower fan disposed in the first room, for blowing air;
- a heat exchanger disposed in the second room, for exchanging heat with the air blown by the blower fan so that the air becomes conditioned air;
- and
- a switching door that is disposed in the housing, wherein:
- the housing includes
- an outside air inlet opening from which outside air is sucked into the first room toward an upstream side of the blower fan,
- a first outlet opening through which the conditioned air in the second room is blown toward a first space of the passenger compartment,
- a second outlet opening through which the conditioned air in the second room is blown toward a second space of the passenger compartment,
- a first passage that connects the second outlet opening to the first room, and
- a second passage that connects the second outlet opening to the second room;
- and
- the switching door changes conditions of the first passage and the second passage so that one of the first passage and the second passage is opened and the other is closed.
