By having the purification module 130 be installed in the installation groove in a drawable manner from one side of the scroll assembly 120, the structure is simple and the user's operation is facilitated.

In an embodiment, referring to fig. 9 to 11, the air duct 123 includes an installation cavity 10 where the blower 110 is installed, an air inlet channel 20 communicating an air inlet end of the installation cavity 10 with the air inlet 121, and a bypass channel 30 communicating an air outlet end of the installation cavity 10 with the air inlet 121, the air inlet channel 20 and the bypass channel 30 are isolated from each other and are communicated through an air communication port 40, the air treatment device 100 further includes a bypass switch door 140, and the bypass switch door 140 is disposed at the air communication port 40, so that the air inlet channel 20 and the bypass channel 30 are alternatively communicated with the air inlet 121.

In this embodiment, the air inlet channel 20 communicates with the air inlet end of the air inlet 121 and the installation cavity 10, and the bypass channel 30 communicates with the air outlet end of the air inlet 121 and the installation cavity 10, so that the portions of the air inlet channel 20 and the bypass channel 30 close to the air inlet 121 can be integrated into a channel, so as to communicate with the air inlet 121 at the same time. The bypass opening/closing door 140 may have a door panel structure, a louver structure, or the like. The air inlet channel 20 and the bypass channel 30 are communicated only through the air communication opening 40, and the bypass switch door 140 is disposed at the air communication opening 40 of the air inlet channel 20 and the bypass channel 30, so that the air inlet 121 can be switched to be communicated with the bypass channel 30, or the air inlet 121 is communicated with the air inlet channel 20. The bypass switch door 140 may be configured to switch one of the bypass channel 30 and the air intake channel 20 to communicate with the air inlet 121 by rotating, may also be configured to switch by sliding, and may also be configured to switch by other manners, which is not limited herein. The switching of the bypass switch door 140 can be driven by a motor or can be manually realized.

The bypass channel 30 communicates the air inlet 121 and the air outlet end of the installation cavity 10, that is, the air outlet 122 and the bypass channel 30 are connected in parallel at the air outlet end of the installation cavity 10. The bypass switch door 140 blocks the communication between the air inlet 121 and the air inlet passage 20, and opens the air inlet 121 and the bypass passage 30. Indoor airflow or other airflow can flow into the bypass channel 30 after being blown out from the air outlet side of the fan 110, and can also flow out from the air outlet 122, so that indoor dirty airflow can be discharged to the outside. At this time, in order to discharge most or all of the indoor airflow from the bypass channel 30, a choke assembly, such as an air outlet switch door or a screen assembly, may be disposed at the air outlet 122, and since the resistance of the air blown out through the bypass channel 30 is significantly smaller than the resistance of the air blown out through the choke assembly, which is equivalent to the short circuit of the air outlet 122 by the bypass channel 30, the airflow blown out by the fan 110 directly flows into the bypass channel 30 and is blown out of the room through the air inlet 121, thereby improving the effect of discharging indoor dirty air of the air treatment device 100 as a whole.

So that the air treatment device 100 has a fresh air mode and a blow-down air mode, when the air treatment device 100 is in the fresh air mode, the air treatment device 100 operates, and the bypass switch door 140 blocks the airflow between the air inlet 121 and the bypass channel 30. The fan 110 works, and at this time, the fan 110 serves as a fresh air fan, outdoor fresh air passes through the air inlet 121 and is introduced into the installation cavity 10 through the air inlet channel 20, then enters the air outlet channel 50, and is purified and filtered by the at least two purification modules 130, and then is blown out to the indoor through the air outlet 122, so that fresh air supply is realized.

When the air treatment device 100 is in the exhaust air mode, the air treatment device 100 is operated, and the bypass switch door 140 blocks the airflow communication between the air inlet 121 and the air inlet duct 20. The fan 110 works, and at this moment, the fan 110 serves as an exhaust fan, indoor dirty air or dirty air in the volute component 120 can be introduced into the installation cavity 10, air flow enters the bypass channel 30, and then the air is blown out of the room through the air inlet 121, so that dirty air is discharged, clean indoor air or air in the volute component 120 is achieved, and user experience is improved.

In this embodiment, switching between the fresh air mode and the blow-off air mode can be achieved only by adding the bypass passage 30 and the bypass switch door 140 to the existing air treatment device 100, and there is no need to additionally add a set of fan 110, so that the whole air treatment device 100 has the advantages of simple structure, few parts, low cost, small volume and small occupied space. And the fan 110 can always keep unidirectional rotation, so the control mode is simple and easy to realize.

In combination with the above embodiment with the bypass channel 30, referring to fig. 9 to 11 again, the air duct 123 further includes an air outlet channel 50 communicating the air outlet 122 and the air outlet end of the installation cavity 10, the fan 110 is a centrifugal fan, the air inlet channel 20 is located at one axial side of the fan 110, the air outlet channel 50 is located at one radial side of the fan 110, and the at least two installation locations 124 are disposed in the air outlet channel 50 and are sequentially arranged along the radial direction of the fan 110.

In the present embodiment, the bypass channel 30 and the air outlet channel 50 are connected in parallel at the air outlet end of the installation cavity 10, and when the bypass switch door 140 blocks the communication between the air inlet 121 and the air inlet channel 20 and conducts the air inlet 121 and the bypass channel 30. After being blown out from the air outlet side of the fan 110, indoor airflow or other airflow can flow into the bypass channel 30 or the air outlet channel 50. By installing the purification module 130 in the air outlet channel 50, because the purification module 130 may cause a certain wind resistance, the resistance of the air blown out through the bypass channel 30 is obviously smaller than the resistance of the air passing through the air outlet channel 50, which is equivalent to the short circuit of the air outlet channel 50 by the bypass channel 30, so that the airflow blown out by the fan 110 directly flows into the bypass channel 30 and is blown out of the room through the air inlet 121. Thus, the whole air processing device 100 can continuously exhaust the indoor airflow out of the room in the sewage air discharging mode, and has high overall efficiency, low energy consumption, better reliability and performance. In order to ensure that the airflow is blown out from the bypass channel 30, an air outlet switch door may be disposed in the air outlet channel 50 or at the air outlet 122, so as to close the air outlet 122 in the blowdown air mode and open the air outlet 122 in the fresh air mode. Through making the air current not pass through purification module 130 under the mode of airing exhaust, pass through purification module 130 under the new trend mode, then can satisfy different scene demands, effectively improve purification module 130's life.

Compared with a vortex fan, the centrifugal fan has the advantages of simple control mode, large air quantity, low noise and high air exchange efficiency. By disposing the air inlet passage 20 at one side of the axial direction of the fan 110, the air outlet passage 50 is disposed at one side of the radial direction of the fan 110. Then, the air inlet channel 20 directly corresponds to the air inlet end of the centrifugal fan, and the air outlet channel 50 directly corresponds to the air outlet end of the centrifugal fan, so that the airflow path is shortened, the wind resistance and the wind loss are reduced, and the energy efficiency of the whole air processing device 100 is improved. Meanwhile, the air outlet duct and the air inlet duct are arranged on two different dimensions of the shell, so that the whole air processing device 100 is more compact in structure and smaller in occupied space.

In one embodiment, referring also to FIG. 4, the bypass switch door 140 is slidably mounted to the volute assembly 120. So that the intake air passage 20 communicates with the intake opening 121, or so that the bypass passage 30 communicates with the intake opening 121. The sliding direction of the bypass switch door 140 can be determined according to the arrangement positions of the bypass channel 30 and the air intake channel 20. For example, when the bypass duct 30 and the air intake duct 20 are arranged vertically, the bypass switch door 140 is slidably mounted to the scroll assembly 120 vertically. Of course, when the bypass duct 30 and the air intake duct 20 are arranged in the left-right direction, the bypass switch door 140 may be switched to slide left and right. The sliding of the bypass switch door 140 may be driven by manual or driving means. Specifically, the driving device includes a driving motor, a gear and a rack structure engaged with each other, the rack structure is connected to the bypass switch door 140, and the driving motor drives the gear to rotate so as to drive the bypass switch door 140 to slide. Through making bypass switch door 140 slide and switch air intake 121 and inlet air duct 20 or bypass passageway 30 intercommunication, compare in the mode that bypass switch door 140 rotated and switches, control mode is simpler, and makes bypass passageway 30 and inlet air duct 20's gas intercommunication mouth 40 can do greatly, and then promotes the air output of blowdown wind.

Specifically, as shown in fig. 1 to 5, the volute assembly 120 includes a housing 125, a volute 126 and a rear shell 127, the volute 126 is installed in the housing 125, the volute 126 defines an installation cavity 10 therein, and the housing 125 is further provided with an air inlet 80 communicating with the installation cavity 10; the bypass switch door 140 is installed at the air passing opening 80, the rear shell 127 is covered at the air passing opening 80, an air inlet channel 20 is defined in the rear shell 127, the air inlet channel 20 is communicated with the installation cavity 10 through the air passing opening 80, the rear shell 127 is provided with an air inlet 121, a bypass channel 30 is defined in the outer shell 125, and the bypass channel 30 is communicated with the air inlet 121 through the air inlet channel 20.
