Title: FAN MOTOR VIBRATION-PROOF STRUCTURE FOR AIR CONDITIONERS AND INDOOR UNIT OF AIR CONDITIONERS
Abstract:
This fan motor vibration-proof structure for air conditioners is equipped with: a body which has a suction port at the top thereof and a blowout port at the bottom thereof; and a propeller fan assembly which is disposed at an upper portion within the body, and blows out the air sucked in from the suction port to the blowout port. The propeller fan assembly has a propeller fan, a fan motor driving the propeller fan, and a bell mouth body. The bell mouth body has: a cylindrical bell mouth portion surrounding the propeller fan; a fan motor fixing portion disposed at the center of the bell mouth portion; a coupling portion that couples the bell mouth portion and the fan motor fixing portion; and mounting portions for mounting the propeller fan assembly. The fan motor is fixed to the fan motor fixing portion of the bell mouth body and the propeller fan, and is formed integrally therewith. The propeller fan assembly is mounted, at the mounting portions, with three or more vibration-proof members interposed therebetween, to a member of the body to which the propeller fan assembly is mounted.
