Abstract: The present invention relates to an air-conditioning device comprising: a case having an interior divided into a first area and a second area, having an indoor inlet and an indoor outlet formed therein such that the first area and an indoor space communicate with each other, and having an outdoor inlet and an outdoor outlet formed therein such that the second area and an outdoor space communicate with each other; a barrier arranged between the first area and the second area inside the case; an indoor blowing fan arranged in the first area so as to form a flow of air from the indoor inlet to the indoor outlet; an outdoor blowing fan arranged in the second area so as to form a flow of air from the outdoor inlet to the outdoor outlet; a first thermoelectric element comprising a first indoor heat exchanger arranged in the first area so as to exchange heat with air passing through the first area, and a first outdoor heat exchanger arranged in the second area so as to exchange heat with air passing through the second area; a case lower-surface formed on the lower surface of the case so as to have an open upper side such that condensed water generated from the first thermoelectric element is collected; and a second thermoelectric element arranged between the first thermoelectric element and the case lower-surface so as to heat the condensed water. The first area and the second area are connected between the case lower-surface and the second thermoelectric element such that the condensed water is distributed across the first area and the second area. The present invention is advantageous in that indoor cooling/heating can be performed without no separate compressor, outdoor unit, and the like, and condensed water can be effectively evaporated.

Abstract: The present embodiment comprise: an inner housing having an inner space formed therein; a rotation shaft assembly supported in the inner housing and having a rotor and a bearing mounted on a rotation shaft thereof; a stator disposed to surround the rotor in the inner housing; an impeller connected to the rotation shaft; an outer housing surrounding the outer periphery of the inner housing and having an inlet body, formed thereat, for guiding air to the impeller. The present embodiment is advantageous in that a heat dissipation vane is provided on the outer peripheral surface of the inner housing to guide air which passes between the inner housing and the outer housing after being suctioned into the inlet body, and thus when being guided by the heat dissipation vane, the air having been moved by the impeller can efficiently absorb heat transferred from the stator to the heat dissipation vane and more stable flow than when colliding against the stator and the rotor, and thus can be quickly discharged.
