Abstract

PURPOSE: To prevent conduction of high temperature heat to the driving shaft in order to protect the bearings on it from burning, by installing an air flow-in enclosure and an air flow-out enclosure between the motor for a blower and the main body of the blower.
CONSTITUTION: A partition 44 with a central hole 44a as an air-passage is installed around the driving shaft 26 that projects from the case of a motor, and an air flow- in enclosure 46 is formed on the motor side of the partition 44 and an air flow-out enclosure 48 is formed on the blower main body side of the partition 44. A flat auxiliary fan 52 is provided in the air flow-out enclosure 48. The auxiliary fan is provided with the boss 52a to be mounted on the driving shaft 26. Accordingly the fan has the air flow-in enclosure 46 and air flow-out enclosure 48 between the motor 14 and the blower main body 16. Rotation of the fan 52 in the air flow-out enclosure 48 takes in the outside air and forcibly passes it through the central hole 44a of the partition 44 around the driving shaft 26 and the air intake opening 54. This air flow prevents conduction of high temperature heat to the driving shaft 26 and protects its bearings 24 and 24' from burning.
