<P>PROBLEM TO BE SOLVED: To provide an exhaust circulation type vacuum cleaner capable of efficiently cooling a circulating air. <P>SOLUTION: The vacuum cleaner includes: a heat transmission body 15 which is communicated to an exhaust air passage 13 and flows the exhaust inside; and a cooling fan 20 which interlocks with a setting of load of an electric blower 9, and changes the volume of the air flowing around the transmission body 15. Thus, the vacuum cleaner can sufficiently and efficiently cool the heat of the circulating air inside the exhaust circulation passage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
