Abstract: Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes a water tank storing water; a visual body forming at least a portion of the water tank and formed of a transparent material; a watering housing disposed in the water tank, drawing water stored in the water tank to pump water to an upper side, and spraying the pumped water; a nozzle disposed in the watering housing and spraying the pumped water; and a watering motor rotating the watering housing. Here, when the watering housing rotates, water sprayed from the nozzle forms at least one spray line on an inner side surface of the visual body.

Abstract: Provided is a humidification and air cleaning apparatus. The humidification and air cleaning apparatus includes: a water tank storing water; a visual body forming at least a portion of the water tank and formed of a transparent material; a top cover assembly disposed over the water tank and including a water supply flow passage disposed therein to supply water into the water tank; a watering housing disposed inside the water tank and rotating inside the water tank; and a watering motor rotating the watering housing. Here, when the watering housing rotates, water supplied to the water supply flow passage drops on the watering housing to be scattered.

Abstract: A cross-flow fan, and blades of a cross-flow fan are provided. The cross-flow fan includes a rotary shaft; a plurality of blades that extends in a direction parallel to the rotary shaft and having a positive pressure surface and a negative pressure surface; and a connector that connects the rotary shaft and the plurality of blades. At least one protrusion that protrudes in a thickness direction and extends in a longitudinal direction of the plurality of blades is formed on the plurality of blades, and by means of the at least one protrusion formed on a blade surface, a flow separation phenomenon caused by friction with the blade surface is suppressed, thereby reducing noise generated by the cross-flow fan.

Abstract: An air conditioner includes a housing that defines an air inlet and an air outlet, a heat exchanger, a blowing fan inside the housing, a lower guide configured to guide, toward the air outlet, air discharged to a rear side of the blowing fan and a lower side of the blowing fan, and an upper guide that is disposed vertically above the lower guide and that defines a discharge flow path with the lower guide. The discharge flow path extends from the blowing fan to the air outlet, and a cross sectional area of the discharge flow path increases toward the air outlet. The upper guide defines a curved surface that is disposed at a downstream end of the upper guide adjacent to the air outlet and that is convex toward the air outlet.
