The present disclosure provides an air duct assembly of a refrigerator, comprising: a main body, the main body being provided with an air inlet toward one side of the main body, a plurality of air outlets formed in areas of two sides of the main body, and an air-uniformizing partition plate provided on the main body and located above the air inlet, and the air-uniformizing partition plate divides the air entered from the air inlet into the areas of two sides of the main body and the air is discharged via the plurality of air outlets.

Air duct assembly and refrigerator

A fume exhaust assembly and a fume exhaust device are provided. The fume exhaust assembly includes a fan, a vortex generating portion, a fume intake pipe, and a fume exhaust pipe. The vortex generating portion includes a vortex pipe and an air intake channel. The air intake channel is in communication with the vortex pipe, an inlet of the air intake channel is connected to the fan, and an outlet of the air intake channel is configured to generate a vortex updraft in the vortex pipe. The fume intake pipe and the fume exhaust pipe are in communication with the vortex pipe. An outlet of the fume intake pipe is arranged above the outlet of the air intake channel. The outlet of the fume intake pipe is configured to be in communication with a low-pressure zone of the vortex updraft. The fume exhaust pipe is connected to an outlet of the vortex pipe.

Fume exhaust assembly and fume exhaust device

A cooking fume purification module and a cooking fume exhaust device are provided. The fume purification module includes a housing, a plurality of dust collection plates and an emitter plate. The housing includes a cylindrical body and a plurality of protruding portions. The body defines an air channel. The plurality of protruding portions extends outwards from the body, and each protruding portion defines an introduction channel in communication with the air channel. The emitter plate is arranged on the protruding portion and provided with a plurality of emitter pins which are located in the introduction channel and face the air channel. The plurality of dust collection plates are arranged in the air channel and spaced apart along an axial direction of the body, and each dust collection plate corresponding to one emitter plate.
