Abstract

An indoor device for an air conditioner is provided. The indoor unit may include: a heat exchanger mounting plate formed with holes for passing air therethrough; a centrifugal fan for sucking air axially through the holes and discharging air radially; a motor for rotating the centrifugal a fan; and a housing to hold the motor and couple the motor to the board. A first magnetic substance and a second magnetic substance generating repulsive force may be provided at a first surface of the plate opposite to the centrifugal fan and at a second surface of the centrifugal fan opposite to the plate, respectively. In the first magnetic substance and the second magnetic substance, the same magnetic poles may form concentric rings, and different magnetic poles may be alternately formed in a radial direction.

Description

technical field [0001] Disclosed herein is an indoor device for an air conditioner. Background technique [0002] Indoor units for air conditioning are well known. However, they suffer from various disadvantages. [0003] An air conditioner is a cooling and heating system that takes in indoor air, exchanges heat from the air with a refrigerant, and discharges the air into the room. In addition, an air conditioner is a device that constitutes a refrigeration cycle, which includes a compressor-condenser-expander-evaporator setup. [0004] Air conditioners can be divided into split air conditioners and integrated air conditioners; in split air conditioners, the outdoor unit (or outdoor unit) and indoor unit (or indoor unit) are installed independently; in integrated air conditioners, the outdoor unit (or outdoor unit) and indoor unit (or indoor unit) are integrally installed. Currently, a multi-type air conditioner is commonly used in which a plurality of indoor units (or i...
