Thin-type blower of heated air

Abstract

A thin-type blower of heated air relates to air regulation device. It comprises a base and a shell installed on the base, and fans, electric component and heating component mounted inside the shell; an air outlet and an air inlet are mounted in front and in rear of the shell; said heating component (is situated in said air outlet; said shell appears in flat case form; said fans inside the shell constitute a fan-module including—thin-type axial fans, the thin-type axial fan further comprises radial-inlet impeller and thin-type motor, the motor is covered up closely by the hub of the radial-inlet impeller, ensuring the fixed connection between the radial-inlet impeller and the rotation part of the motor. Compared with the prior art, the said thin-type blower features low thickness, smart volume, light weight, low material consumption and low cost.

1 . A thin-type blower of heated air, comprising a base Hand a shell installed on the base, and fans, electric component and heating component mounted inside the shell; an air outlet and an air inlet are mounted in front and in rear of the shell; said heating component is situated in said air outlet; characterized in that: said shell appears in flat case form; said fans inside the shell constitute a fan-module including—thin-type axial fans, the thin-type axial fan further comprises radial-inlet impeller and thin-type motor, the motor is covered up closely by the hub of the radial-inlet impeller, ensuring the fixed connection between the radial-inlet impeller and the rotation part of the motor. 
   
   
       2 . A thin-type blower of heated air according to  claim 1 , being characterized in that: the said fan-module includes at least two sets of thin-type axial fan electrically in parallel or in series connection, the various thin-type axial fans are distributed on a plane or on two planes and respectively intersecting to form an obtuse angle.
