Abstract:
1. A hair iron, comprising: an upper case and a lower case hinge-jointed at each one end thereof and being freely opened or closed; an upper heater plate for generating heat and a lower heater plate for generating heat, each of the heater plates mounted to the sides facing each other of the upper and lower cases adjacent to the other end of each of the upper and lower cases, respectively; a fan assembly for blowing air toward the lower heater plate, the fan assembly including a housing coupled to the hinge-jointed one end of the lower case opposite to the lower heater plate, the housing having air inlets through which external air flows in and two air outlets, the fan assembly having a fan contained inside the housing; an upper supporting member for supporting and fixing the upper heater plate and a lower supporting member for supporting and fixing the lower heater plate, the upper supporting member being disposed between the upper case and the upper heater plate, the lower supporting member being disposed between the lower case having both side edges and the lower heater plate, wherein the lower supporting member is formed along both side edges thereof with a plurality of air-ejecting holes; an upper cover member engaged with the upper case between the upper supporting member and the hinge-jointed one end of the upper case and a lower cover member engaged at both side edges thereof with the lower case between the lower supporting member and the hinge-jointed one end of the lower case, the upper cover member covering an inside of the upper case uncovered by the upper supporting member, the lower cover member covering an inside of the lower case uncovered by the lower supporting member; two air passages for transferring the air blown from the fan assembly to the air-ejecting holes, one of the two air passages being in communication with one of the two air outlets at one end thereof and being in communication with the air-ejecting holes of one of the both side edges of the lower supporting member at the other end thereof, the other of the two air passages being in communication with the other of the two air outlets at one end thereof and being in communication with the air-ejecting holes of the other of the both side edges of the lower supporting member at the other end thereof, each of the air passages being constructed in the form of grooves formed continuously along one of the both sides of the lower case, wherein one part of the one of the two air passages is formed by one of the both side edges of the lower case and one of the both side edges of the lower cover member and the other part of the one of the two air passages is formed by the one of the both side edges of the lower case and one of the both side edges of the lower supporting member, wherein one part of the other of the two air passages is formed by the other of the both side edges of the lower case and the other of the both side edges of the lower cover member and the other part of the other of the two air passages is formed by the other of the both side edges of the lower case and the other of the both side edges of the lower supporting member; and two means for opening and closing the air passage, one of the two opening and closing means mounted to the lower cover member adjacent to one of both side edges of the lower case, the other of the two opening and closing means mounted to the lower cover member adjacent to the other of both side edges of the lower case, wherein the opening and closing means includes a blocking plate configured to block the air passage and a lever for turning the blocking plate, and wherein when one of the air passages is closed by the blocking plate, the air is supplied toward the lower heater plate only through the other of the air passages and is ejected only from the air-ejecting holes being in communication with the other of the air passages.
