The indoor air treatment device of the invention can realize the following three basic working modes:
the fresh air introducing operation mode, in which the OA-SA airflow paths in fig. 4 are separately performed, for sucking fresh air from the outdoor space and purifying it before sending it to the indoor space; after entering the airflow distribution chamber 24 from the first fresh air opening 2411 or the second fresh air opening 2412, the air flows to the air purification chamber 23, and the intake air chamber 22 sucks purified air from the air purification chamber 23 and sends the purified air to the indoor space from the air supply opening 221/222;
an internal circulation operation mode in which the air flow paths from RA2 to SA in fig. 4 are individually performed to suck turbid air from the indoor space and to send the air to the indoor space after being purified; the air flows to the air cleaning chamber 23 after entering the air flow distribution chamber 24 from the air suction opening 2421/2422, and the air intake chamber 22 sucks cleaned air from the air cleaning chamber 23 and sends the cleaned air to the indoor space from the air supply opening 221/222;
an operation mode of introducing fresh air and performing internal circulation simultaneously, in which an airflow path from OA to SA and an airflow path from RA2 to SA in FIG. 4 are performed simultaneously, for sucking fresh air from the outdoor space and sending the fresh air to the indoor space after being purified, and for sucking turbid air from the indoor space and sending the turbid air to the indoor space after being purified; outdoor air enters the airflow distribution chamber 24 from the first fresh air inlet 2411 or the second fresh air inlet 2412 and then flows to the air purification chamber 23, meanwhile, indoor air enters the airflow distribution chamber 24 from the air suction port 2421/2422 and then also flows to the air purification chamber 23, and the air inlet chamber 22 sucks purified air from the air purification chamber 23 and sends the purified air to the indoor space from the air supply port 221/222;
in addition, the indoor air processing device can realize an exhaust operation mode, the exhaust air chamber 25 has a return air inlet 251 for communicating the indoor space and an exhaust air outlet 252a/252b for communicating the outdoor space; when the exhaust fan 33 rotates, air enters the exhaust air chamber 25 from the air return opening 251 and is exhausted to the outdoor space through the exhaust openings 252a/252 b.
The three basic modes of operation described above may be performed independently of each other, or the air-bleeding mode of operation may be performed independently of each other (i.e., the air flow paths from RA1 to EA in fig. 4 may be performed independently), and the air-bleeding mode of operation may be performed simultaneously with any one of the three basic modes of operation described above.
The air exhaust cavity 25 is independently arranged, and the air exhaust cavity 25 is not communicated with the airflow distribution cavity 24, the air purification cavity 23 or the air inlet cavity 22. Like this, when indoor air treatment device carries out the operation of airing exhaust, the air current of airing exhaust can not cause the turbulent flow and the turbulent flow of air current with the air current conflict in air current distribution chamber 24, air purification chamber 23 or the air inlet chamber 22, just so can not disturb the normal clear of inner loop mode of operation and the new trend of drawing the work mode, and the air current route of independent airing exhaust effectively prevents to crowd the space that occupies air current distribution chamber 24, air purification chamber 23 or air inlet chamber 22, be favorable to guaranteeing the new trend induction volume, finally guarantee that indoor air quality satisfies user's comfort level demand.
When the indoor air treatment device of the present invention is used, the indoor air treatment device is installed indoors, and the first fresh air opening 2411 or the second fresh air opening 2412 is communicated with an outdoor space; the indoor air processing device can realize a fresh air introducing working mode, an internal circulation working mode, a working mode of simultaneously introducing fresh air and internal circulation, and an independent air exhaust working mode or a combination of the air exhaust working mode and any one of the working modes; moreover, because the air flow paths for exhausting air are independently arranged, the air flow paths do not collide with other air flow paths to generate turbulence and turbulent flow; therefore, various working modes of the indoor air processing device can be matched and combined in a compatible mode, so that indoor air can be effectively processed, and the indoor air quality is improved.
In the indoor air processing device of the present invention, for the convenience of manufacturing, an air distribution member 14 is designed, an air distribution chamber 24 is provided in the air distribution member 14, as shown in fig. 3b and 3d, a partition wall 141 is provided between a fresh air separation chamber 241 and a suction separation chamber 242, and a communication port 2413 is provided in the partition wall 141. In order to enable the airflow distribution chamber 24 to realize the function of switching the airflow path, please refer to fig. 2b, fig. 2c, fig. 3b and fig. 3d, the upper end of the fresh air separation chamber 241 is communicated with the air purification chamber 23, and the upper end of the suction air separation chamber 242 is not communicated with the air purification chamber 23, so that the air entering the fresh air separation chamber 241 from the fresh air inlet can directly enter the air purification chamber 23, and the air entering the suction air separation chamber 242 from the air suction inlet 2421/2422 needs to enter the fresh air separation chamber 241 through the communication port 2413 before entering the air purification chamber 23. As shown in fig. 3b, 3c, 3d and 3e, switching of the operation mode of the indoor air treatment device of the present invention can be achieved by controlling the first valve plate 41 and the second valve plate 43. The first driving mechanism 42 and the second driving mechanism 44 may be rotating electric machines, and the control device controls the rotation angle of the rotating shaft of the rotating electric machine, so as to control the opening degree of the first valve plate 41 or the second valve plate 43, thereby controlling the magnitude of the air flow according to the actual demand of the indoor air quality. In addition, it is also advantageous to ensure miniaturization of the air treatment device.
