Vehicle air conditioner
In a vehicle air conditioner, a first warm air diversion passage is a tunnel-shaped passage that is provided near a first side air outlet and takes in warm air and causes the air to flow without mixing with cool air. A second warm air diversion passage is a passage inside a tunnel that is provided near a second side air outlet and takes in warm air and causes the air to flow without mixing with cool air. A diversion passage section includes an in-tunnel guide wall that directs the warm air flowing through the first warm air diversion passage toward the first side air outlet, and an in-tunnel guide wall that directs the warm air flowing through the second warm air diversion passage toward the second side air outlet.
1. An air conditioner for a vehicle, comprising:
an air conditioning casing having therein a passage through which a conditioned air flows to an inside of a vehicle compartment;
a defroster air outlet provided on the air conditioning casing, the defroster air outlet being an outlet through which the conditioned air is blown toward a window in the vehicle compartment;
a cooling heat exchanger disposed inside the air conditioning casing, the cooling heat exchanger absorbing heat from air passing therethrough and supplying cool air downstream in an air flow;
a heating heat exchanger disposed inside the air conditioning casing, the heating heat exchanger radiating heat to air passing therethrough and supplying warm air downstream in an air flow;
a cool air passage provided in the air conditioning casing, the cool air passage being a passage through which the cool air that has been cooled in the cooling heat exchanger flows;
a warm air passage provided in the air conditioning casing, the warm air passage being a passage through which the warm air that has been heated in the heating heat exchanger flows;
a diversion passage section provided downstream of the cool air passage and the warm air passage in the air flow and upstream of the defroster air outlet in the air flow inside the air conditioning casing, the diversion passage section including a plurality of cool air diversion passages communicating with the cool air passage, and a plurality of warm air diversion passages communicating with the warm air passage; and
an air mixing portion provided upstream of the defroster air outlet in the air flow inside the air conditioning casing, the air mixing portion being a portion in which the cool air flowing out of the plurality of cool air diversion passages and the warm air flowing out of the plurality of warm air diversion passages are mixed with each other, wherein
the defroster air outlet includes a first side air outlet through which the conditioned air passes to be blown to one of both side parts in a vehicle width direction in the vehicle compartment, a second side air outlet through which the conditioned air passes to be blown to other of the both side parts in the vehicle width direction in the vehicle compartment, and a center air outlet provided between the first side air outlet and the second side air outlet in the vehicle width direction,
the plurality of warm air diversion passages includes at least a first warm air diversion passage and a second warm air diversion passage that are separated from each other in the vehicle width direction,
at least one of the plurality of cool air diversion passages is disposed adjacent to the first warm air diversion passage and the second warm air diversion passage between the first warm air diversion passage and the second warm air diversion passage in the vehicle width direction,
the first warm air diversion passage is provided near the first side air outlet and is a passage through which the warm air from the warm air passage flows without mixing with the cool air flowing out of the cool air passage,
the second warm air diversion passage is provided near the second side air outlet and is a passage through which the warm air from the warm air passage flows without mixing with the cool air flowing out of the cool air passage, and
the diversion passage section includes a first guide that directs the warm air flowing through the first warm air diversion passage toward the first side air outlet, and a second guide that directs the warm air flowing through the second warm air diversion passage toward the second side air outlet.
2. The air conditioner according to claim 1 , wherein
at least one of the first guide and the second guide is an in-passage guide wall provided in an inside of either the first warm air diversion passage or the second warm air diversion passage.
3. The air conditioner according to claim 1 , wherein
at least one of the first guide and the second guide is an outlet-side guide wall provided in an outlet portion of either the first warm air diversion passage or the second warm air diversion passage.
4. The air conditioner according to claim 1 , wherein
the first warm air diversion passage and the second warm air diversion passage extend in a direction perpendicular to the vehicle width direction,
a position of an outlet portion of the first warm air diversion passage in the vehicle width direction and a position of a boundary portion, which separates the center air outlet and the first side air outlet, in the vehicle width direction are overlapped with each other in an extending direction of the first warm air diversion passage, and
a position of an outlet portion of the second warm air diversion passage in the vehicle width direction and a position of a boundary portion, which separates the center air outlet and the second side air outlet, in the vehicle width direction are overlapped with each other in an extending direction of the second warm air diversion passage.
