The duct assembly 200 includes a cabinet 100 portion. The housing 100 provides, in part, mounting space for other components of the device. As an alternative embodiment, the cross-sectional shape of the air chute assembly 200 may also be circular or other polygonal shape.

The cabinet 100 of the duct assembly 200 is disposed on a bathroom ceiling and has at least one intake opening 300 and at least one outlet opening 400. Specifically, the air inlet 300 and the air outlet 400 are both located at the lower side of the box 100 and are arranged in a staggered manner.

As shown in fig. 2, an air source 500 is disposed in the air duct assembly 200, and the air source 500 includes a fan assembly, or may be another device capable of outputting an air flow.

In this embodiment, the fan assembly includes a housing 505, a rotating shaft 501 rotatably connected to the center of the housing 505, a wind wheel 503 provided on the rotating shaft 501, and a motor 502 for driving the rotating shaft 501 to rotate. The motor 502 is utilized to drive the wind wheel 503 to rotate, and the wind wheel 503 generates flowing air flow to be conveyed into the air duct assembly 200. A damping pad sleeve 504 is arranged between the shell 505 and the box 100, so that vibration generated when the motor 502 drives the wind wheel 503 to rotate is reduced, and noise is reduced.

Further, in the present embodiment, the air duct assembly 200 is at least divided into a hot air duct 201 and a cold air duct 202 which are communicated with each other, the hot air duct 201 and the cold air duct 202 are the same air duct, and a heat exchanger 600 is further disposed in the air duct.
