Abstract: A filter structure capable of removing dust is proposed. The filter structure includes a circular rim part; a frame, extending from the rim part, for installing a motor; a dust collection net attached to the frame; a brush which is in close contact with the dust collection net and is rotated by the motor; an opening, formed at a lower end of the rim part, for discharging dust; an open part formed at one side of the dust collection net; and a concave groove part having an outside coupled to the open part and in one-side communication with the opening at the rim part.
Abstract: An air-conditioning device has a dust removing function, including: an outdoor air introducing portion for introducing outdoor air into a case; an outdoor air discharge portion having a blowing fan for supplying the indoor environment with the outdoor air introduced through the outdoor air introducing portion; an indoor air introducing portion for introducing indoor air; and an indoor air discharge portion having a blowing fan for discharging the indoor air introduced through the indoor air introducing portion into the outdoor environment, wherein the air-conditioning device includes: a filter coupled inside the entrance of the outdoor air introducing portion to be able to collect dust that is introduced together with outdoor air; and an opening formed through the lower end of the edge portion of the filter.
Abstract: The present invention relates to a damper-integrated blower having improved airtightness, which comprises a blower casing a having a suction port and a blower casing b fastened to the casing a from the opposite side; a vane stopper protrusion is formed on bottom surface of the exhaust port, and a vane contact housing part is formed above the exhaust port; damper motor screw fixing parts integrally protrude from the outer upper surface of the vane contact housing part of the blower casing a; a damper motor shaft hole is bored in a damper motor shaft hole protrusion part which is integrally formed on the outer upper side of the vane contact housing part of the blower casing a; a vane rotation shaft protrudes from the inner surface of a damper motor shaft hole protrusion part of the blower casing b facing the damper motor shaft hole protrusion part; an eccentric damper motor shaft of a damper motor is introduced into the damper motor shaft hole so as to connect with the blower casing a; a vane as a single member
