Vehicle air-conditioning device

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.
