Claims (2)

(57) [Claims] A first zone communicating with at least the suction port, a tertiary zone connecting to the air outlet, and a tertiary zone connected to the interior of the case body having a suction port and an air outlet provided on a panel surface facing the indoor side; A centrifugal chamber that divides the room air into the case body from the suction port through the primary zone, the secondary zone, and the tertiary zone to the outlet through the zone and the secondary zone adjacent to the primary zone. It is composed of a blowing means comprising a blower of a blower type, and a cylindrical rotary dehumidifying element which contacts the air passing through the secondary zone to the tertiary zone, adsorbs moisture in the air and dries. Dehumidifying / drying means, heat collecting means for performing heat recovery by passing a part of air on the way from the secondary zone to the tertiary zone through the rotary dehumidifying element of the dehumidifying means, Regenerating means for heating the air recovered by heat and making a U-turn to re-pass the regenerating air through the rotary dehumidifying element of the dehumidifying means, and exhaust means for exhausting the air regenerated by the regenerating means to the outside. Ventilating means for exhausting air on the way from the primary zone to the secondary zone to the outside, and regeneration air heated and recovered by the heat recovery means to the tertiary zone and exhausted from the outlet. Drying / heating switching means for causing the rotation type dehumidifying element to have a regeneration chamber disposed at a location corresponding to a regeneration zone and a heat recovery zone on the tertiary zone side of the rotary dehumidifier. The introduction path of the divided air after adsorbing moisture from the heat recovery processing part of the rotary dehumidifying element, and the divided air is fed to the regeneration processing part side of the rotary dehumidifying element.
The outlet path formed by turning is partitioned by a partition wall, and a ventilation heating surface for heating the divided air after moisture adsorption from the heat recovery processing portion of the rotary dehumidifier in the introduction path has a rectangular electric heater. On the other hand, the drying / heating switching means is formed by a switching damper capable of controlling opening and closing of a communication port provided on a downstream side wall of the electric heater facing the tertiary zone side of the regeneration chamber. In the open state, the regeneration air heated by the electric heater is allowed to reach the tertiary zone, and the ventilation heating surface of the electric heater is inclined with respect to the heat recovery processing portion of the rotary dehumidifier. Wherein the open / close allowable space for the switching damper is formed on the U-turn portion side of the introduction path. 2. The tertiary zone in the case body is provided with heating means for heating the air dehumidified and dried by the dehumidifying means and exhausting the heating air from the outlet. The dehumidifying / drying apparatus according to Claim.
