Abstract: A centrifugal fan having improved efficiency and noise reduction includes a hub configured to have a central part combined with a rotary shaft, a shroud spaced apart from the hub, and a plurality of blades provided between the hub and the shroud. The shroud includes outer circumferential parts each connecting the trailing edges of a plurality of respective adjacent blades. Each outer circumferential part is asymmetrically formed based on the center of the outer circumferential part.

Abstract: The present disclosure relates to a centrifugal fan and a method for manufacturing the same. The centrifugal fan can easily implement a three-dimensional blade by including a main plate, a blade, and a shroud that injection-molded as one body, thereby reducing the weight of the centrifugal fan and improving the operating efficiency. In addition, since assembly processes such as fastening or welding are unnecessary when manufacturing the blade, the defect rate of the blade can be reduced and the fluidity performance can be prevented from deteriorating due to traces of welded areas.

Abstract: Disclosed is a ceiling type air conditioner that can implement a horizontal air flow to provide an indirect wind to a user with a simple structure. To this end, the ceiling type air conditioner according to the present disclosure includes an inner case in which a blower and a heat exchanger are built-in, and a blow passage for guiding air passed through the heat exchanger downward is formed; an inner flow path body which is disposed below the inner case and has a suction flow path for sucking air into the inner case so as to communicate vertically; and an outer flow path body which is spaced outward from the inner flow path body and disposed below the inner case, and forms a discharge flow path, between the inner flow path body, communicating with the blow passage; wherein an outer circumferential surface of the inner flow path body comprises a first concave portion formed to be concave, a first horizontal portion extended horizontally outwardly from a lower end of the first concave portion, and a vertical portion extended vertically downwardly from an outer end of the first horizontal portion.

Abstract: An air guide for a ceiling-type air conditioner is applied to the ceiling-type air conditioner comprising: an indoor unit having a heat exchanger and a blower embedded therein, and having a plurality of blowing passages for discharging, to the outside, air which has passed through the heat exchanger; a plurality of inlets for receiving the air discharged through the plurality of blowing passages; and a discharge panel having an inner space, of which at least a portion communicates with the plurality of inlets, and a ring or arc-shaped opening for discharging, into a room, air which has flowed into the inner space. The air guide includes: at least two partition parts formed in parallel to the radial direction of the opening, and dividing the inner space in the circumferential direction; and a curved part connecting the at least two partition parts, and formed in an arc shape, and is detachably inserted into the inside of the opening from the outside of the opening.
