The working principle of the invention is as follows:
the fresh air purification device of the present invention provides two flow path options, one is a pretreatment flow path and the other is a through flow path, and the two flow path options are realized by the rotation reversing of the rotating cover plate 22.
The operation of the present invention will be described below with fresh air flowing through the pretreatment flow path. Fresh air is sucked from the air inlet by the exhaust fan, at the moment, the rotary driver 21 of the flow channel selection assembly drives the rotary cover plate 22 to rotate, the air inlet hole communicated with the through area is completely blocked, and the air inlet hole communicated with the pretreatment area is partially or completely opened. Fresh air flows through the pretreatment flow channel, is washed and cooled at the heat exchange plates 27, flows down from the water inlet pipe 28 on the heat exchange plates 27, sequentially flows through the plurality of layers of heat exchange plates 27, and finally flows out from the water outlet pipe 29, and the fresh air is upwards contacted with the water flow in a counter-current manner, and then flows out from the first through hole. After the fresh air flows out from the first through hole, the rotating vane of the impeller 31 is impacted to rotate, and the fresh air is rotated to the inner wall of the shell 10 while the impeller 31 rotates, so that the steam-water centrifugal separation of the fresh air is realized. During centrifugal separation, a large amount of water is thrown out and then discharged from the water discharge pipe, and when the centrifuged fresh air contacts the inclined vane plates 32, water is continuously blocked by the inclined vane plates 32 and flows into the water discharge pipe together with the centrifuged water. Meanwhile, the fresh air continues to flow to the purification mechanism 40, is sequentially purified by the multilayer structure of the purification mechanism 40, and is finally discharged to the indoor from one end of the air outlet of the shell 10.
When the straight-through flow channel needs to be selected for circulation, the controller controls the rotary driver 21 to drive the rotary cover plate 22 to rotate, the air inlet hole communicated with the straight-through area is opened, and the air inlet hole communicated with the pretreatment area is closed. Fresh air directly enters the straight-through flow channel from the air inlet end of the shell, directly flows into the purification mechanism 40 to be purified after passing through the impeller 31 and the inclined blade plate 32, and finally is discharged to the indoor.
In addition, the rotary vane driver drives the impeller 31 to rotate, air at the air inlet is pumped into the cylinder body after the rotary vane driver rotates, and the air is discharged from the air outlet, so that an air pumping mechanism is formed, and the circulation of fresh air is accelerated.
The fresh air purification device can select the flow channel according to the outdoor temperature and the quality of outdoor air, thereby reducing the load of the purification mechanism 40, improving the purification capacity, carrying out pre-cooling treatment on the air before purification, reducing the load of an indoor air conditioner, saving energy and protecting environment.
The top and the bottom in the present invention refer to the top and the bottom of the fresh air purification device in the use state, and are not limited as specific orientations.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
