Abstract

A cooling and heating air conditioner installed in an electric vehicle, having a cooling and heating air conditioning unit including a cooling device that produces cooled air, and a heating device that produces heated air, wherein the cooling and heating air conditioning unit sends the cooled air produced by the cooling device or the heated air produced by the heating device to a vehicle interior, a cooling and heating air conditioning controller that sets the cooling and heating air conditioning unit to a cooling mode for sending the cooled air produced by the cooling device, a heating mode for sending the heated air produced by the heating device, or an AUTO mode for automatically selecting the cooling mode or the heating mode at least based on a temperature of the vehicle interior so as to control the cooling and heating air conditioning unit according to a set mode.

First claim

The invention claimed is:

1. A cooling and heating air conditioner installed in an electric vehicle having a secondary battery, comprising:
a cooling and heating air conditioning unit comprising:
a cooling device that produces cooled air, and
a heating device that produces heated air,
wherein the cooling and heating air conditioning unit sends the cooled air produced by the cooling device or the heated air produced by the heating device to a vehicle interior;

a cooling and heating air conditioning controller that sets the cooling and heating air conditioning unit to a cooling mode for sending the cooled air produced by the cooling device, a heating mode for sending the heated air produced by the heating device, or an AUTO mode for automatically selecting the cooling mode or the heating mode at least based on a temperature of the vehicle interior so as to control the cooling and heating air conditioning unit according to a set mode;
an air conditioning setting portion that sets the cooling and heating air conditioning controller to the cooling mode;
a heater setting portion that sets the cooling and heating air conditioning controller to the heating mode;
an AUTO setting portion that sets the cooling and heating air conditioning controller to the AUTO mode;
an air conditioning indicator that indicates an activated state of the cooling device;
a heater indicator that indicates an activated state of the heating device; and
an AUTO indicator that indicates a set state set by the AUTO setting portion,
wherein the cooling device and the heating device are activated by electric energy from a driving battery of the electric vehicle,
wherein the cooling and heating air conditioning controller directs the AUTO indicator to indicate the set state of the AUTO mode and directs the air conditioning indicator and the heater indicator to indicate the activated state of the cooling device and the heating device according to the set state of the AUTO mode when the AUTO mode is selected by the AUTO setting portion, and
wherein the cooling and heating air conditioning unit carries out a dehumidification operation when the air conditioning indicator and the heater indicator indicate that the cooling device and the heating device are active, respectively.

2. The cooling and heating air conditioner according to claim 1 , wherein the air conditioning setting portion, the heater setting portion, the AUTO setting portion, the air conditioning indicator, the heater indicator, and the AUTO indicator are formed in one switch panel.

3. The cooling and heating air conditioner according to claim 1 , wherein the air conditioning setting portion, the heater setting portion and the AUTO setting portion are integrated with the air conditioning indicator, the heater indicator and the AUTO indicator, respectively.

4. The cooling and heating air conditioner according to claim 1 ,
wherein the heater setting portion is located on an upper side of the air conditioning setting portion,
wherein a temperature setting portion is provided adjacent to the heater setting portion and the air conditioning setting portion vertically aligned,
wherein a set temperature of the heating device or the cooling device increases when an upper portion of the temperature setting portion is pushed, and
wherein the set temperature of the heating device or the cooling device decreases when a lower portion of the temperature setting portion is pushed.

5. The cooling and heating air conditioner according to claim 1 , wherein the cooling and heating air conditioning unit carries out a ventilation operation when the air conditioning indicator and the heater indicator indicate that the cooling device and the heating device are inactive, respectively.

6. A method of controlling a cooling and heating air conditioner installed in an electric vehicle having a secondary battery, including:
a cooling and heating air conditioning unit including a cooling device activated by electric energy from a driving battery of the electric vehicle to produce cooled air and a heating device activated by the electric energy from the driving battery to produce heated air, the cooling and heating air conditioning unit sending the cooled air produced by the cooling device or the heated air produced by the heating device to a vehicle interior;
an air conditioning setting portion that sets to a cooling mode for sending the cooled air produced by the cooling device;
a heater setting portion that sets to a heating mode for sending the heated air produced by the heating device;
an AUTO setting portion that sets to an AUTO mode for automatically selecting the cooling mode or the heating mode at least based on a temperature of the vehicle interior;
an air conditioning indicator that indicates an activated state of the cooling device;
a heater indicator that indicates an activated state of the heating device; and
an AUTO indicator that indicates a set state set by the AUTO setting portion, the method comprising:
setting the cooling and heating air conditioning unit to the cooling mode, the heating mode, or the AUTO mode, so as to control the cooling and heating air conditioning unit according to a set mode;
directing the AUTO indicator to indicate a set state of the AUTO mode and directing the air conditioning indicator and the heater indicator to indicate the activated state of the cooling device and the heating device according to the set state of the AUTO mode when the AUTO mode is selected by the AUTO setting portion; and
carrying out a dehumidification operation when the air conditioning indicator and the heater indicator indicate that the cooling device and the heating device are active, respectively.

7. The cooling and heating air conditioner according to claim 1 , wherein the cooling and heating air conditioning controller releases the AUTO mode when the cooling and heating air conditioning unit carries out a dehumidification operation.
