Abstract

A flow channel located downstream of a temperature regulating device branches off into a first flow channel and a second flow channel. In the first flow channel, a windshield's-side flow channel connecting to a windshield's-side air outlet port and an adsorbent's-side flow channel connecting to an adsorbent inflow section are formed. At the time of regeneration treatment of an adsorbent, by interrupting communication between the first flow channel and the second flow channel, interrupting communication between a temperature regulating device outflow section and the windshield's-side air outlet port, and making the temperature regulating device outflow section and the adsorbent inflow section communicate with each other, the air warmed by the temperature regulating device is preferentially guided to the adsorbent.

First claim

What is claimed is:

1. A vehicle air-conditioning device comprising:
an inside-air inlet port configured to suck in air inside a vehicle cabin;
an outside-air inlet port configured to suck in air outside the vehicle cabin;
an adsorbent configured to adsorb water contained in the air, including an adsorbent inflow section into which the air sucked in through the inside-air inlet port flows and an adsorbent outflow section from which the air flows;
a temperature regulating device configured to regulate a temperature of the air, including a temperature regulating device inflow section into which the air flowed from the adsorbent or the air sucked in through the outside-air inlet port flows, and a temperature regulating device outflow section from which the air flows;
a windshield's-side air outlet port configured to blow the air flowed from the temperature regulating device toward a windshield in the vehicle cabin; and
another air outlet port configured to blow the air flowed from the temperature regulating device toward an area other than the windshield in the vehicle cabin,
wherein a first flow channel is connected to the temperature regulating device outflow section of the temperature regulating device,
a second flow channel is connected to the first flow channel,
a windshield's-side flow channel and an adsorbent's-side flow channel are formed in the first flow channel, downstream of a connection point of the first flow channel and the second flow channel, the windshield's-side flow channel configured to guide the air to the windshield's-side air outlet port and the adsorbent's-side flow channel configured to guide the air to the adsorbent inflow section,
another flow channel is formed in the second flow channel, and configured to guide the air to the other air outlet port,
a first door is provided between the first flow channel and the second flow channel, and configured to switch between a state in which the first flow channel and the second flow channel communicate with each other and a state in which the communication between the first flow channel and the second flow channel is interrupted,
a second door is provided in the windshield's-side flow channel, and configured to switch between a state in which the temperature regulating device outflow section and the windshield's-side air outlet port communicate with each other and a state in which the communication between the temperature regulating device outflow section and the windshield's-side air outlet port is interrupted,
a third door is provided in the adsorbent's-side flow channel, and configured to switch between a state in which the temperature regulating device outflow section and the adsorbent inflow section communicate with each other and a state in which the communication between the temperature regulating device outflow section and the adsorbent inflow section is interrupted, and
at a time of regeneration treatment of the adsorbent, the air warmed by the temperature regulating device is guided to the adsorbent, by placing the first door and the second door in the state of interruption, and placing the third door in the state of communication.

2. The vehicle air-conditioning device according to claim 1 , wherein the adsorbent comprises two adsorbents,
the vehicle air-conditioning device concurrently forms an outside-air introduction circuit configured to guide the air sucked in through the outside-air inlet port to the temperature regulating device, and an inside-air circulation circuit configured to guide the air sucked in through the inside-air inlet port to the temperature regulating device, and
at a time of regeneration treatment of one of the two adsorbents, the vehicle air-conditioning device is configured to suck in air required for regeneration through the outside-air inlet port, warm the sucked-in air by the temperature regulating device, guide the warmed air to the adsorbent inflow section of the one adsorbent, and exhaust the air flowing from the adsorbent outflow section of the one adsorbent.

3. The vehicle air-conditioning device according to claim 2 , further comprising an outside-air introduction flow channel configured to guide the air sucked in through the outside-air inlet port to a space between the adsorbent outflow section and the temperature regulating device inflow section,
wherein the two adsorbents are disposed separately from each other in a vehicle-width direction, and
a position of the outside-air introduction flow channel in the vehicle-width direction is a position between the two adsorbents in the vehicle-width direction.

4. The vehicle air-conditioning device according to claim 2 , wherein two blowers configured to generate a flow of air are disposed separately from each other in a vehicle-width direction, and
positions of the two adsorbents in the vehicle-width direction are positions between the two blowers in the vehicle-width direction.

5. The vehicle air-conditioning device according to claim 1 , wherein the adsorbent is disposed in a position closer to a front of a vehicle than the windshield's-side air outlet port.

6. The vehicle air-conditioning device according to claim 1 , further comprising a dust filter between the inside-air inlet port and the adsorbent inflow section.
