An air purifier and a control method thereof. The air purifier includes a main body having an air inlet and an air outlet, a fan mounted in the main body, rotational speed of which is changed according to a user-desired air flow rate, cyclones disposed in parallel with each other under the fan, at least one open/close unit to open and close at least one of the cyclones. The open/close unit may include a valve member to open and close an outflow pipe of the cyclone, and a stepping motor to rotate the valve member. An anemometer is mounted to at least one of the cyclones. Accordingly, since the air purifier can measure a speed of air flow in the cyclone and correspondingly change the operating number of the dust-collecting cyclones in an open state, the air purifier can achieve a predetermined dust-collecting performance even when the speed of the air flow in the cyclone is reduced.

A cyclone and a cyclone air purifier include a device with an inlet port structure such that a suction area through which a fluid is suctioned into the cyclone is increased, pressure loss is reduced, and a centrifugal force applied to the fluid is increased, to improve performance of air purification and to reduce noise. The cyclone includes a cylinder into which a fluid is suctioned, a guide extended from the cylinder, an outlet pipe provided in a center of the cylinder to guide a fluid that inversely rises to be discharged, and a vortex induction member provided between the cylinder and the outlet pipe to form vortex channels.

An air purifier includes a bell-mouth having an enhanced structure to prevent an increase of noise at a particular frequency when air flows into the blowing fan through the bell-mouth. The air purifier includes a housing, a filter unit and a blowing fan placed inside the housing, and a bell-mouth placed toward an intake side of the blowing fan. The bell-mouth includes an inlet port formed at a center of the bell-mouth, a flow guide extending from a periphery of the inlet port toward the blowing fan, and a flat section positioned to discontinue the flow guide to increase a distance between the blowing fan and the bell-mouth. The flat section is formed at the section in the range of about 240°˜330° with respect to a starting point of a scroll inside the bell-mouth. The flat section may have a saw-tooth shape to effectively distribute air passing therethrough.

A blower having a divergence guide portion to reduce flow loss and discharge noise and an air conditioner having the same are provided. The blower includes a scroll casing, suction holes provided at opposite positions of the scroll casing, a discharge hole provided at a top position of the scroll casing, a centrifugal fan received in the scroll casing, and a divergence guide portion gently diverging air to the discharge hole after passing through the centrifugal fan to diffuse the air to both sides of the discharge hole.

A blowing device having an air suction guide with an improved structure to reduce blowing operational noise, and an air conditioning apparatus having the blowing device. The blowing device includes a blowing fan, a fan casing placed to cover the blowing fan and having a suction port, and a suction guide provided in the suction port of the fan casing to guide inlet air to the blowing fan. The suction guide includes a flow guide part extending forward from an edge of the suction port of the fan casing by a predetermined length. Due to the flow guide part of the blowing device, the inlet air flows through the suction port at a constant flowing speed and in a state of laminar flow. Therefore, the blowing device reduces a variation in a pressure applied onto blades of the blowing fan by the inlet air, and reduces operational noise thereof.
