Problems solved by technology

Therefore, in the case of applying the mixed flow fan to the air circulator, when only the discharge grill is installed on the front surface of the air circulator, there is a problem that the air blown from the mixed flow fan is difficult to be sent far forward.
[0014] In addition, the air circulator includes a fan motor that rotates the mixed flow fan, and there is a problem that the front and rear width of the air circulator increases due to the fan motor

Abstract

Provided are a fan assembly and an air conditioner including the fan assembly, the fan assembly is additionally provided with discharge vanes between a mixed flow fan and a discharge grill to control the direction of air sent from the mixed flow fan so that the air is discharged as far as possible . To this end, the fan assembly according to the present invention includes: a fan case unit having an air inlet formed on its rear surface and an air discharge port formed on its front surface; a mixed flow fan rotatably arranged in the fan case unit ; the fan motor, which rotates the mixed flow fan; the discharge vane, which is arranged in front of the mixed flow fan to control the direction of the air sent from the mixed flow fan; The air direction of the blade, wherein the discharge vane may include: an annular inner rim, the fan motor is coupled with the inner side of the inner rim; an annular outer rim, which is arranged behind the inner rim, and its center is The center of the rim is arranged coaxially and has a diameter greater than that of the inner rim; and a plurality of vane ribs arranged between the inner and outer rims to connect the inner and outer rims to each other and arranged radially spaced apart from each other in the circumferential direction.

Description

technical field [0001] The present disclosure relates to a fan assembly and an air conditioner including the fan assembly, and more particularly, to a fan assembly with a mixed flow fan and an air conditioner including the fan assembly. Background technique [0002] Generally, an air conditioner includes a compressor, a condenser, an evaporator, and an expander, and utilizes an air conditioning cycle to supply cool or warm air to a building or room. [0003] The air conditioner includes an air purifying device or a humidifying device, and further includes a blower fan for flowing air to suck external air and then discharge the external air. [0004] The blower fan includes a fan motor and a blower fan that is coupled to a rotation shaft of the fan motor and sucks and discharges air while rotating by being driven by the fan motor. [0005] Blowing fans are divided into axial fans, centrifugal fans and mixed flow fans according to the flow direction. [0006] The axial fan i...
