Installation structure for drive motor of double suction blower

Abstract

Disclosed herein is an installation structure for a drive motor of a double suction blower which can provide the optimal installation position for the drive motor so as to offer an excellent flow rate of air when the drive motor is installed at any one of both intake ducts of an impeller.

1 . An installation structure for a drive motor of a double suction blower, comprising:
 an impeller which is configured to axially draw in air at axially both sides thereof and to radially expel the drawn air and which is divided into two halves by a partition wall;   a case accommodating the impeller, the case including air intake holes formed at both sides thereof to allow air to be introduced into the impeller at both sides of the impeller and including an outtake guide duct to guide the air radially expelled outside from the impeller; and   a drive motor installed at one side of the impeller and coupled to the center of the partition wall to rotate the impeller,   wherein the drive motor is disposed at a position in which the drive motor is partially inserted into the impeller from an outer end of the impeller.   
     
     
         2 . The installation structure for a drive motor of a double suction blower according to  claim 1 , wherein the impeller includes intake ducts axially at both sides thereof to allow air to be drawn in the impeller by the drive motor, the intake duct being flared outward. 
     
     
         3 . The installation structure for a drive motor of a double suction blower according to  claim 2 , wherein the drive motor is disposed at a position in which the drive motor is partially inserted into a minimum intake diameter line of the intake ducts. 
     
     
         4 . The installation structure for a drive motor of a double suction blower according to  claim 3 , wherein the drive motor includes a housing configured to have cylindrical shape, and a diameter line of the housing is within a range of 75% to 85% of the minimum intake diameter line of the intake duct. 
     
     
         5 . The installation structure for a drive motor of a double suction blower according to  claim 4 , wherein the drive motor is disposed in the impeller through the minimum intake diameter line such that an end of the drive motor is positioned at a distance from an outer end of the impeller, the distance being within the range of 20% to 30% of the minimum intake diameter line.
