The present disclosure relates a dryer and amethod for controlling the same. The dryer includes a front case including a first opening surrounded by an air guide that protrudes forward and a pluralityof exhaust holes formed around the first opening; a rear case coupled to the front case and including a second opening surrounded by a housing guide that protrudes backward, the second opening overlapping the first opening; a fan housing that is coupled to the first and second openings, is moveable in forward and backward directions along the air guide and the housing guide, and includes a blastfan therein; and a heater that is formed on the fan housing and heats and ejects wind generated by the blast fan; and the direction of the wind ejected from the heater is changed depending on forwardand backward movement of the fan housing.

The invention discloses heat dissipation equipment, which comprises a fan, at least two heat dissipation air ducts communicated with the fan, and adjustable wind resistance baffle plates arranged at wind inlets of the heat dissipation air ducts. The heat dissipation air ducts are used for placing at least one heating component; the fan is used for providing wind for the heat dissipation air ductsto reduce the temperature of the heating component; and the adjustable wind resistance baffle plates are used for adjusting the quantity of the wind entering the heat dissipation air ducts. The heat dissipation equipment in the embodiment of the invention comprises the fan, the at least two heat dissipation air ducts communicated with the fan, and the adjustable wind resistance baffle plates arranged at the wind inlets of the heat dissipation air ducts, so the quantity of the wind entering the heat dissipation air ducts can be adjusted through the adjustable wind resistance baffle plates; therefore, when the quantity of the wind entering one of the heat dissipation air ducts needs to be changed, the change of the quantity of the wind entering the heat dissipation air ducts can be implemented only by adjusting the adjustable wind resistance baffle plate, and the structures of the heat dissipation air ducts are prevented from being redesigned.

The invention provides an integrated high-energy reactive oxygen ion air purification device which comprises purification boxes, a fresh air filter fixedly penetrates through the side face of the lower end of the purification box, and a through groove is formed in the center of a middle partition plate in a penetrating mode; the lower end of the through groove fixedly communicates with the air outlet end of a centrifugal fan, and the upper end of the through groove fixedly communicates with an air distributing pipe; a plurality of ventilating grooves are vertically formed in the side wall of the air distributing pipe in a penetrating mode, and iron generators are fixedly arranged on the inner walls, located on the two sides of the air distributing pipe, of the purification boxes; and air outlet holes are evenly formed in the air distributing partition plate, and shutter air sending openings are formed in a box cover and provided with an air speed detecting probe and an oxygen ion content detection probe correspondingly. According to the integrated high-energy reactive oxygen ion air purification device, a specially-made air distributing system is adopted for a reaction section so that the space of the whole reaction section can be evenly filled with fresh air, the standing time is increased, then the fresh air sufficiently acts with the ion generator of the reaction section, ion gas rich in positive and negative oxygen ions is generated, and the air is purified.
