Abstract

The invention discloses a dryer ventilating device and further provides a dryer using the ventilating device. The dryer ventilating device comprises a main air pipe (1) and fans (2). Air outlets (21)of the fans (2) are formed in the wall of the main air pipe (1) and communicate with the interior of the main air pipe (1). According to the dryer ventilating device, parts such as impellers which arearranged in an air channel are omitted, and the mode that the fans generate airflow and drive air is adopted, so that the stable air pressure and air speed are formed in the main air pipe, and the drying process is stably conducted advantageously; and meanwhile, the outlet air pipe does not need to be lengthened, and thus energy saving is better achieved.

Description

technical field [0001] The present application relates to the technical field of drying equipment, in particular to a dryer ventilation device and a dryer. Background technique [0002] The ventilation of the dryer generally adopts a fan. The fan mainly uses structures such as impellers to convert the rotating mechanical energy into gas pressure energy and kinetic energy, and transport the gas out. At present, the main fan structures are centrifugal, axial flow, cross flow and so on. However, due to the cutting effect of the above-mentioned fan impellers on the air, the air flow at the outlet of the fan will be disturbed, and the outlet duct needs to be extended to form a stable wind pressure and wind speed. [0003] Therefore, how to provide a fan with stable airflow as a ventilation device for the dryer is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In order to solve the above technical problems, the first ...
