As shown in fig. 5 and 6, when the switching member 700 blocks the first passage 210, the indoor air can only enter the second heat exchange air duct 370 through the second passage 220, so as to achieve the effect of improving the heat exchange efficiency of the second heat exchanger 320. As shown in fig. 7 and 8, when the first channel 210 and the second channel 220 are both in a circulation state, indoor air can enter the fresh air duct 110 through the first channel 210 and enter the second heat exchange air duct 370 through the second channel 220, and the anti-freezing effect of the total heat exchange core 100 and the heat exchange enhancement effect of the second heat exchanger 320 are achieved at the same time. As shown in fig. 9 and 10, when the first channel 210 and the second channel 220 are both in the blocking state, the air treatment device 10 is in the state of closing the anti-freezing and enhancing the heat exchange.
Specifically, the switch 700 is used to cover the first exhaust inlet 212 and/or the second exhaust inlet 221. The first exhaust inlet 212 is covered or opened by controlling the switch 700 so as to plug or open the first channel 210; and/or the second exhaust inlet 221 is covered or opened by controlling the switching piece 700 so as to realize the blocking or opening of the second passage.
Referring to fig. 1 and 2, in an embodiment, the first exhaust inlet 212 and the second exhaust inlet 221 are both formed on the exhaust member 200, and the switch member 700 is movably disposed on the exhaust member 200, so that the switch member 700 can move to the first exhaust inlet 212 and cover the first exhaust inlet 212, and/or so that the switch member 700 can move to the second exhaust inlet 221 and cover the second exhaust inlet 221.
In this embodiment, the switch 700 is rotatably disposed on the exhaust member 200, so that the switch 700 can rotate to the first exhaust inlet 212 and cover the first exhaust inlet 212, and/or so that the switch 700 can rotate to the second exhaust inlet 221 and cover the second exhaust inlet 221. By moving the switch 700 relative to the exhaust member 200, the switch 700 can cover the first exhaust inlet 212 and/or the second exhaust inlet 221, so as to achieve freeze protection and/or enhance heat exchange switching.
In another embodiment, the switch 700 may also be used to cover or open the first air vent 211 and/or the second air vent 214. As long as the control of the flow or the blocking of the first channel 210 and the second channel 220 can be achieved.
In another embodiment, there are at least two switches 700, different switches 700 are respectively and movably disposed on the air exhaust device 200, at least one switch 700 is used to cover or open the first air exhaust inlet 212 or the first air passing opening 211, and at least another switch 700 is used to cover or open the second air exhaust outlet or the second air passing opening 214. The switching pieces 700 are arranged to control the on-off of the first channel 210 and the second channel 220 respectively, so that the flexibility of control can be improved.
In this embodiment, the switching member 700 is a fan-shaped plate, which is disposed on the exhaust member 200 and is rotatable about a rotation axis with respect to the exhaust member 200, and the first exhaust inlet 212 and the second exhaust inlet 221 are disposed about the rotation axis. When the sector plate is controlled to rotate around the rotation axis, the sector plate can rotate to the first exhaust air inlet 212 or the second exhaust air inlet 221, and different exhaust air inlets are covered. Specifically, the switch 700 is foldable, so as to change the area of the sector plate, so as to control the coverage area of the first exhaust inlet 212 and/or the second exhaust inlet 221, and achieve the purpose of adjusting the air volume and the air speed.
In the present embodiment, the number of the first exhaust inlet 212 is at least two, and different first exhaust inlets 212 are provided around the rotation axis. Switch 700 may overlie a different first exhaust inlet 212. The number of the second discharge air inlets 221 is at least two, and different second discharge air inlets 221 are provided around the rotation axis. The switch 700 may cover a different second exhaust inlet 221.
In an embodiment, the air processing apparatus 10 further includes a temperature detector disposed at the fresh air inlet 112 of the fresh air duct 110, the temperature detector is configured to detect a temperature at the fresh air inlet 112, and the temperature detector is electrically connected to the switching member 700. Specifically, the temperature detector is disposed at the third opening 630 of the mounting case 600, and the temperature detector is used to detect the temperature at the third opening 630 of the mounting case 600. Because the temperature detector is arranged at the fresh air inlet 112, the temperature of the air entering the fresh air duct 110 through the fresh air inlet 112 can be further judged. In this embodiment, when it is detected whether the temperature at the fresh air inlet 112 reaches the freezing temperature, if the temperature reaches the freezing temperature, the switching member 700 may be controlled to open the first channel 210, so that the indoor air can be collected into the air before entering the fresh air duct 110 through the first channel 210 and the first air passing opening 211 through the first air exhaust inlet 212, so as to increase the temperature of the air and prevent the total heat exchange core 100 from freezing. For example, when the temperature detector detects that the temperature value is lower than zero, the switch 700 is caused to open the first channel 210. When the temperature detector detects that the temperature value is lower than minus five degrees, the switch 700 is enabled to open the first channel 210.
The air treatment device 10 is simple in pipeline and air channel design, indoor exhaust energy is recovered by the exhaust piece 200, heat exchange efficiency is effectively improved, energy conservation and emission reduction are achieved, and operation performance and energy efficiency of the air treatment device 10 are improved. Meanwhile, the air treatment device 10 can prevent the full heat exchange core 100 from freezing, thereby achieving an anti-freezing effect.
