Abstract: The present invention relates to a dehumidification and humidification apparatus for vehicles using an adsorbent which is capable of feeding a dehumidified air for preventing fogging of window glass and a humidified air for improvement in comfortableness, and is simplified in construction thereof and reduced in size thereof. The dehumidification and humidification apparatus for vehicles according to the present invention comprises a casing (1), and a blower (2), an adsorbent module (3) and an air passage switching device (4) which are accommodated in the casing.

Abstract: In a dehumidification/humidification device, a blower and an adsorbent module are contained in a casing. In other embodiment, the blower, the adsorbent module, and a flow passage-changing device are contained in the casing. The adsorbent module includes an adsorbing element formed by carrying an adsorbent on a permeable element and a heater directly disposed on the adsorbing element. The state of the electrification of the heater is changed and an air-blowing direction or a flow passage is changed, whereby a dehumidified air is discharged from a first suction/discharge port (or discharge port), and a humidified air is discharged from a second suction/discharge port (or discharge port).

Abstract: A vehicle interior structure that may realize a more amenable vehicle interior space by making communication between occupants sitting on a pair of vehicle seats easier. The vehicle interior structure includes: a pair of vehicle seats; and a sound-reflecting communication unit for conveying a sound produced from occupants sitting, respectively, on the pair of vehicle seats to the other occupant, while reflecting and converging the sound. The sound-reflecting communication unit forms a concave shape along a virtual ellipse, focuses of which are respectively at positions of heads of the occupants.

In other embodiment, the blower (2), the adsorbent module (3), and a flow passage-changing device (4) are contained in the casing. The adsorbent module (3) comprises an adsorbing element (30) formed by carrying an adsorbent on a permeable element and a heater (31) directly disposed on the adsorbing element. The state of the electrification of the heater (31) is changed and an air-blowing direction or a flow passage is changed, whereby a dehumidified air is discharged from a first suction/discharge port (or discharge port), and a humidified air is discharged from a second suction/discharge port (or discharge port).

Abstract: A dehumidifier/humidifier for vehicle comprising a casing as air flow channel and, accommodated therein in sequence, first air blower (2a), first flow channel switching unit (4a), adsorbent module (3), second flow channel switching unit (4b) and second air blower (2b). The adsorbent module (3) is built by directly disposing first adsorbent element (31) and second adsorbent element (32) on plate surfaces of Peltier element (30), respectively. By reversing the electric current flowing through the Peltier element (30) and switching the flow channel by means of the first flow channel switching unit (4a) and the second flow channel switching unit (4b), dehumidified (or humidified) air is continuously blown out from first blowout hole (11) and humidified (or dehumidified) air is continuously blown out from second blowout hole (12).
