Abstract

Provided is a vehicle-mounted temperature control device (2) capable of suppressing resource wasting or environmental contamination during an idling stop, an easily installed vehicle-mounted refrigeration unit which blows off cooled or warmed air to the inside of a vehicle, and selectively cooling or warming not only a napping cabin behind the driver'"'"'s seat, but also the driver'"'"'s seat. The vehicle-mounted temperature control device includes a refrigeration unit having a refrigeration cycle in which a compressor, a condenser, and an evaporator to which driving electric power is supplied by a battery 5 are annularly connected; a temperature control chamber formed from a heat-insulating wall body having a blowoff air trunk and a return air trunk and having a circulation fan and the evaporator in the refrigeration cycle housed therein; and a machine chamber in which the compressor, the condenser, and a radiation fan which cools the compressor and condenser are disposed. The refrigeration unit (2) is attached to the inside of a napping cabin (4) behind the driver'"'"'s seat (3), and the cool or warm air generated by the evaporator being blown off to either the driver'"'"'s seat or the inside of the napping cabin, or both so that temperature is controlled.

Claims

1. A vehicle-mounted temperature control device comprising:

a refrigeration unit having

a refrigeration cycle in which a compressor, a condenser, and an evaporator to which driving electric power by a battery is supplied are annularly connected;

a temperature control chamber formed from a heat-insulating wall body having a blowoff air trunk and a return air trunk and having a circulation fan and the evaporator in the refrigeration cycle housed therein; and

a machine chamber in which the compressor, the condenser, and a radiation fan which cools the compressor and condenser are disposed,

the refrigeration unit being attached to the inside of a napping cabin behind the driver'"'"'s seat, and

the cool air or warm air generated by the evaporator being blown off to either the driver'"'"'s seat or the inside of the napping cabin, or both so that temperature is controlled.

2. The vehicle-mounted temperature control device according to claim 1,

wherein a means which discharges the exhaust air generated during the driving of the compressor to the outside of a vehicle is provided, and an air feed duct is connected to at least one of the blowoff air trunk and the return air trunk in the temperature control chamber.

3. The vehicle-mounted temperature control device according to claim 2,

wherein the air feed duct is an extension duct capable of being supplied to the driver'"'"'s seat.

4. The vehicle-mounted temperature control device according to claim 2,

wherein the air feed duct is provided so as to extend to a space on the ceiling portion of the cabin, and a wind direction controller is provided at the end of the air feed duct.

5. The vehicle-mounted temperature control device according to claim 4, wherein the wind direction controller is controlled by a position detecting means for a human being.

6. The vehicle-mounted temperature control device according to claim 2,

wherein an air feed means separate from the air feed duct is provided along with the air feed duct.

7. The vehicle-mounted temperature control device according to claim 6,

wherein a damper which switches wind direction is arranged at a branching portion between the air feed duct, and the air feed means separate from the air feed duct.

8. The vehicle-mounted temperature control device according to claim 2,

wherein the other end of the air feed duct is provided so as to extend to a seating portion of the driver'"'"'s seat, a seating mat detachably provided at the seating portion, or a sleeping mat for napping provided in the napping cabin.

9. The vehicle-mounted temperature control device according to claim 8, wherein the air permeability near the outer surface of the seating portion, the seating mat, or the sleeping mat is improved so as to obtain ventilation from the air feed duct.

10. The vehicle-mounted temperature control device according to claim 1,

wherein a means which discharges the exhaust air generated during the driving of the compressor to the outside of a vehicle is provided, and the refrigeration unit attached to the inside of the napping cabin is covered with a partition and is demarcated from the napping cabin.

11. The vehicle-mounted temperature control device according to claim 1,

wherein the space between the driver'"'"'s seat and the napping cabin is demarcated by a partition.

12. The vehicle-mounted temperature control device according to claim 10,

wherein the partition is formed from a curtain having heat insulation performance or sound insulation performance, or both performances.

13. The vehicle-mounted temperature control device according to claim 11,

wherein the partition is formed from a curtain having heat insulation performance or sound insulation performance, or both performances.
