Title:
UNPOWERED COLD/WARM AIR BLOWER EMPLOYING THERMOELECTRIC ELEMENT
Document Type and Number:
WIPO Patent Application WO/2018/174640
Kind Code:
A1
Abstract:
The present invention relates to an unpowered cold/warm air blower that can be driven by minimal power. The cold/warm air blower according to the present invention comprises: a housing having a plurality of first magnetic bodies; a blowing fan positioned on the housing; a blowing portion comprising a second magnetic body that interacts with the first magnetic bodies and rotates a rotating shaft of the blowing fan; and a self-electricity-generating portion for converting rotational power of the rotating shaft into electric energy. The blowing fan can be rotated by minimal power using the magnetic field formed by the first magnetic bodies and the second magnetic body. Rotational power resulting from rotation of the blowing fan can be converted into electric energy by the self-electricity-generating portion and then stored or selectively used as power for driving an electric device. The temperature of introduced air is controlled using an thermoelectric element. The distance of air introduced through the blowing fan can be improved using an air beam.
