1. An air conditioner for a vehicle, comprising:
- a single blower that blows air into a vehicle compartment having a specific region in which an occupant is sitting and a non-specific region in which no occupant is sitting;
a plurality of air outlets that blow the air blown by the single blower into the vehicle compartment;
an air-conditioning mode switching portion that switches between air conditioning modes by opening or closing the plurality of air outlets; and
a controller that controls an operation of the air-conditioning mode switching portion, whereinthe air conditioning modes include;
a normal air conditioning mode in which air conditioning is performed both in the specific region and the non-specific region; and
a specific-region prioritizing air conditioning mode in which a volume of air that is blown to the non-specific region is decreased as compared to a volume of air that is blown to the non-specific region in the normal air conditioning mode,the plurality of air outlets include;
a specific-region side air outlet that blows air to the specific region; and
a non-specific-region side air outlet that blows air to the non-specific region,the controller starts operating the specific region prioritizing air conditioning mode when an occupant detection sensor detects that an occupant is present only in the specific region, andwhen the specific-region prioritizing air conditioning mode is performed, the controller controls the air-conditioning mode switching portion to keep the air flow consistent then calculates a blower suction pressure such that if the blower suction pressure increases then the controller increases an opening degree of the non-specific-region side air outlet, so as to decrease the volume of air that is blown to the specific region relatively by increasing the volume of air that is blown to the non-specific region.

Abstract
A vehicle air conditioner includes a blower for blowing air into a space of a vehicle compartment, and an air-conditioning mode switching portion for switching between air conditioning modes. The air conditioning modes include a normal air conditioning mode in which air conditioning of a specific region including a driver seat and air conditioning of a non-specific region not including the specific region in the space of the vehicle compartment are performed, and a specific-region prioritizing air conditioning mode in which an air conditioning capability for the non-specific region is decreased as compared to the normal air conditioning mode. The air-conditioning mode switching portion adjusts the air conditioning capability for the non-specific region based on a pressure of air drawn into the blower, in the specific-region prioritizing air conditioning mode.

12. An air conditioner for a vehicle, comprising:
-
a single blower that blows air into a vehicle compartment having a specific region in which an occupant is sitting and a non-specific region in which no occupant is sitting; a plurality of air outlets that blow the air blown by the single blower to the vehicle compartment; an air-conditioning mode switching portion that switches between air conditioning modes by opening or closing the plurality of air outlets; and a controller that controls an operation of the air-conditioning mode switching portion, wherein the air conditioning modes include; a normal air conditioning mode in which air conditioning is performed both in the specific region and the non-specific region; and a specific-region prioritizing air conditioning mode in which a volume of air that is blown to the non-specific region is decreased as compared to a volume of air that is blown to the non-specific region in the normal air conditioning mode, the plurality of air outlets include; a specific-region side air outlet that blows air to the specific region; and a non-specific-region side air outlet that blows air to the non-specific region, the controller starts operating the specific region prioritizing air conditioning mode when an occupant detection sensor detects that an occupant is present only in the specific region, when the specific-region prioritizing air conditioning mode is performed, the controller controls the air-conditioning mode switching portion to keep the air flow consistent then calculates a blower suction pressure such that if the blower suction pressure increases then the controller increases an opening degree of the non-specific-region side air outlet, so as to decrease the volume of air that is blown to the specific region relatively by increasing the volume of air that is blown to the non-specific region, and the controller individually controls the volume of air that is blown to the specific region separate from the volume of air that is blown to the non-specific region.

13. An air conditioner for a vehicle, comprising:
-
a single blower that blows air into a vehicle compartment having a specific region in which an occupant is sitting and a non-specific region in which no occupant is sitting; a plurality of air outlets that blow the air blown by the single blower into the vehicle compartment; an air-conditioning mode switching portion that switches between air conditioning modes by opening or closing the plurality of air outlets; and a controller that controls an operation of the air-conditioning mode switching portion, wherein the air conditioning modes include; a normal air conditioning mode in which air conditioning is performed both in the specific region and the non-specific region; and a specific-region prioritizing air conditioning mode in which a volume of air that is blown to the non-specific region is decreased as compared to a volume of air that is blown to the non-specific region in the normal air conditioning mode, the plurality of air outlets include; a specific-region side air outlet that blows air to the specific region; and a non-specific-region side air outlet that blows air to the non-specific region, the controller starts operating the specific region prioritizing air conditioning mode when an occupant detection sensor detects that an occupant is present only in the specific region, and when the specific-region prioritizing air conditioning mode is performed, the controller controls the air-conditioning mode switching portion to keep the air flow consistent then calculates a blower suction pressure and an air conditioning load and increases an opening degree of the non-specific-region side air outlet when the air conditioning load increases, so as to decrease the volume of air that is blown to the specific region relatively by increasing the volume of air that is blown to the non-specific region. - View Dependent Claims (14, 15, 16, 17, 18, 19)
