The dehumidifying ventilation unit includes housing, is rotated in the housing and is provided with runner, is provided with what is axially connected on the runner
Passage, the passage are provided at both ends with silk screen, silica-gel desiccant are provided with the passage, described logical when the runner rotates
Road covers the air inlet and the air outlet all the time, and some heating wire are provided with the passage, and the rotor periphery is set
Have some to contact, each heating wire both ends are connected with a pair of contact, are provided with the housing at air outlet
A pair of of contact, the contact connect power supply and coordinate with the contact, and the runner side rotates and is provided with fan, the fan
It is connected by shaft with motor, first gear is provided with the shaft, second gear, the runner is provided with the housing
Inner ring sets rack gear, and the first gear is engaged with the second gear, and the second gear is engaged with the gear ring, described
It is additionally provided with cabinet and coordinates the baffle ring rotated with the runner, the baffle ring is equipped with the first opening, institute towards the air inlet
The center of rotation for stating passage towards the runner is provided with the second opening, is provided with what is be aligned with the air outlet on the housing
First through hole and the second through hole with being aligned on the inside of the baffle ring.This kind of switchgear is driven by the rotation of motor when in use
Fan rotates, and air-flow passes through silica-gel desiccant from the second through hole air inlet by the first opening of baffle ring and the second opening of runner
Afterwards again from air inlet inlet air, from air outlet by silica-gel desiccant from first through hole outlet air, in inlet air, air is by runner
Passage moisture absorption, prevent steam from entering in cabinet, while motor rotates drive runner slowly rotate, touched at gas outlet
Point coordinates with contact is powered heating wire, and heating silica-gel desiccant causes the moisture evaporation in silica-gel desiccant to discharge.
In above-mentioned technical proposal, it is preferred that contact described in each pair in the passage is separated by partition plate.Using the structure
So that steam does not pass through partition plate during electric-heating-wire-heating between two partition plates, play the role of obstructing steam.
Compared with prior art, the present invention have the advantages that：This kind of switchgear is turned by motor when in use
Dynamic to drive fan to rotate, air-flow passes through silica gel from the second through hole air inlet by the first opening of baffle ring and the second opening of runner
Again from air inlet inlet air after drier, from air outlet by silica-gel desiccant from first through hole outlet air, in inlet air, air passes through
Passage moisture absorption on runner, prevents steam from entering in cabinet, drives runner slowly to rotate while motor rotates, in outlet
Kou Chu contacts coordinate with contact is powered heating wire, and heating silica-gel desiccant causes the moisture evaporation in silica-gel desiccant to discharge.
