The centrifugal fan includes a base plate connected to a rotating shaft of a motor, a plurality of blades joined to a surface of the base plate, and a ring-shaped shroud joined to the plurality of blades to face the base plate. The blade is provided in such a way that a length of one end joint portion joined to the base plate is greater than a length of another end joint portion joined to the shroud, and with respect to a plane perpendicular to a rotation axis, an angle between a first straight line, which connects a leading edge position and a trailing edge position of the one end joint portion, and a straight line passing through a center point of the first straight line and a rotation center is less than an angle between a second straight line, which connects a leading edge position and a trailing edge position of the other end joint portion, and a straight line passing through a center point of the second straight line and the rotation center.

Air conditioner including a centrifugal fan

Disclosed herein is an air conditioner capable of guiding air in a desired direction with an adjusted speed without marring the appearance to solve the above-described problems. An air conditioner comprising a ceiling-embedded type indoor unit configured to discharge air into an indoor room through an air outlet simultaneously sucking indoor air through an air inlet, wherein a air conditioner comprises, a main flap configured to guide a direction of air discharged from a air outlet in a preset direction, and a sub-flap configured to guide the direction of air between the main flap and the sub-flap in the preset direction, wherein a length of a main flap in a direction where air flows is longer than that of the sub-flap in the direction where air flows.

Air conditioner

Disclosed herein is an outdoor unit for an air conditioner including a blowing apparatus for reducing suction loss of a propeller fan generated in corners of a housing and achieving high efficiency of blowing and low noise. The blowing apparatus includes a housing including a wall in which an outlet is formed, a propeller fan positioned in the inside of the housing, the propeller fan facing the outlet, and a diffuser positioned at a discharging side of the propeller fan, and forming the outlet, wherein the diffuser includes an inclined surface inclined with respect to a rotation axis of the propeller fan, and an inclination angle of the inclined surface to the rotation axis of the propeller fan changes according to a circumferential direction of the diffuser.

Outdoor unit for air conditioner

A blower having high efficiency and low noise by actively controlling airflow in the blower, and an air conditioner having the blower is provided. The air conditioner has a blower. The blower includes a fan having a hub and at least one blade provided on an outer circumferential surface of the hub, a motor to rotatably drive the hub, a shroud configured to surround the periphery of the fan and at least one actuator installed in the shroud and configured to form an airflow along an inner circumferential surface of the shroud.

Blower and air conditioning apparatus having the same

Disclosed herein is an air conditioner having improved maintenance ability by arranging a fan to be attached or detached without removing a guide member. An air conditioner includes a main body with an opening formed in the bottom, a ceiling panel arranged under the main body for covering the opening, and having a sucking hole through which air is sucked in and a discharging hole through which air is discharged, a fan detachably installed inside the main body through the opening for guiding indoor air to be sucked in through the sucking hole in the vertical direction and discharged in the horizontal direction, a heat exchanger arranged in the radial direction of the fan to be separated from the fan for performing heat exchange on the air discharged from the fan and a guide member arranged between the fan and the heat exchanger in the radial direction of the fan to be separated from the fan for guiding the air discharged from the fan toward the heat exchanger.
