Vehicular air conditioner
A vehicular air conditioner includes a first outlet that blows a conditioned air frontward to flow past a neck part of an occupant on a seat, and a second outlet that is provided below the first outlet and blows the conditioned air upward to flow past an armpit part of the occupant. The second outlet blows the conditioned air to merge with the conditioned air blown from the first outlet. The second outlet blows the conditioned air with an airflow volume larger than an airflow volume of the conditioned air from the first outlet such that the conditioned air blown from the second outlet guides the conditioned air blown from the first outlet to flow along a face of the occupant.
1. A vehicular air conditioner supplying a conditioned air to an occupant seated on a seat provided in a vehicle compartment, the vehicular air conditioner comprising:
an air conditioning unit that generates the conditioned air adjusted in temperature;
a first outlet that blows the conditioned air to flow past a neck part of the occupant frontward of the seat; and
a second outlet that is provided below the first outlet and blows the conditioned air upward to flow past an armpit part of the occupant, the second outlet blowing the conditioned air to merge with the conditioned air blown from the first outlet, wherein
the second outlet is configured to blow the conditioned air with an airflow volume larger than an airflow volume of the conditioned air from the first outlet such that the conditioned air blown from the second outlet guides the conditioned air blown from the first outlet to be supplied to a face of the occupant,
a flow of the conditioned air from the first outlet is substantially parallel to a seat bottom surface of the seat, and
a flow of the conditioned air from the second outlet is substantially parallel to a seat back surface of the seat.
2. The vehicular air conditioner according to claim 1 , wherein the second outlet is an outlet port of an outlet duct provided on a lateral side of a backrest portion of the seat.
3. The vehicular air conditioner according to claim 2 , wherein the outlet port is open at a position frontward of the backrest portion.
4. The vehicular air conditioner according to claim 2 , wherein the outlet port is open at a position within a lower half of the backrest portion in a height direction.
5. The vehicular air conditioner according to claim 2 , wherein the outlet duct is attached to the seat.
6. The vehicular air conditioner according to claim 1 , wherein the second outlet is a pair of outlet ports provided at symmetrical positions with respect to a right-left direction of the seat, and the pair of outlet ports are symmetrically inclined toward a center of the seat in the right-left direction to blow the conditioned air.
7. The vehicular air conditioner according to claim 1 , wherein the first outlet is an outlet port provided in an outlet duct detachably attached to the seat.
8. The vehicular air conditioner according to claim 1 , wherein
the air conditioning unit is a refrigeration cycle device including:
a compressor that pumps a refrigerant;
a condenser through which the refrigerant pumped from the compressor flows;
a pressure reducing device that depressurizes the refrigerant flowing through the condenser;
an evaporator through which the refrigerant depressurized by the pressure reducing device flows; and
a blowing unit that blows an air to the evaporator and the condenser.
9. The vehicular air conditioner according to claim 1 , further comprising a housing that accommodates the air conditioning unit, wherein the housing is attached to the seat.
10. The vehicular air conditioner according to claim 9 , wherein the housing is attached to a seat portion of the seat and located below the seat portion.
11. The vehicular air conditioner according to claim 1 , being applied to an electric vehicle.
12. The vehicular air conditioner according to claim 1 , which is only one air conditioner in a vehicle compartment.
13. The vehicular air conditioner according to claim 1 , wherein
the first outlet blows the conditioned air at a first outlet angle with respect to the seat back surface,
the second outlet blows the conditioned air at a second outlet angle with respect to the seat back surface, and
the second outlet angle is more acute and steeper than the first outlet angle.
14. A vehicular air conditioner supplying a conditioned air to an occupant seated on a seat provided in a vehicle compartment, the vehicular air conditioner comprising:
an air conditioning unit that generates the conditioned air adjusted in temperature;
a first outlet that blows the conditioned air to flow past a neck part of the occupant front of the seat; and
a second outlet that is provided below the first outlet and blows the conditioned air upward to flow past an armpit part of the occupant, the second outlet blowing the conditioned air to merge with the conditioned air blown from the first outlet, wherein
the second outlet is configured to blow the conditioned air with an airflow speed higher than an airflow speed of the conditioned air from the first outlet such that the conditioned air blown from the second outlet guides the conditioned air blown from the first outlet to be supplied to a face of the occupant,
a flow of the conditioned air from the first outlet is substantially parallel to a seat bottom surface of the seat, and
a flow of the conditioned air from the second outlet is substantially parallel to a seat back surface of the seat.
