For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] The air valve 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0055] like Figure 1 As shown, the air valve 10 according to the embodiment of the utility model includes a mounting frame 1, air guide blades 2 and a driving motor 3.

[0056] Specifically, Figure 1 As shown, the installation frame 1 has an air port 11 therein, and the air port 11 is mainly used for air flow to pass through.

[0057] like Figure 1 and Figure 2 As shown, the air guide blade 2 is one and rotatably arranged in the air outlet 11, and is used to open or close the air outlet 11. When the air valve 10 is assembled, the assembly of a single air guide blade 2 is relatively simple, the overall structure of the air valve 10 is relatively simple, and the cost of the air valve 10 is relatively low. When the air guide blade 2 opens the air outlet 11, the air guide blade 2 has a smaller obstruction on the air outlet 11, so that the windshield area of ​​the air valve 10 can be smaller, thereby reducing the air volume loss in the air treatment device 100.

[0058] like Figure 1 , Figure 6 and Figure 7As shown, the drive motor 3 is arranged outside the mounting frame 1 and connected to the wind guide blade 2, and is used to drive the wind guide blade 2 to rotate. One end of the wind guide blade 2 is connected to the output shaft of the drive motor 3, and the drive motor 3 can provide driving force for the wind guide blade 2.

[0059] The air valve 10 can be used in the air treatment device 100. When the air treatment device 100 is closed, the air guide blade 2 can close the air outlet 11, and the sealing effect inside the air treatment device 100 is better. After the air treatment device 100 is turned on, the air outlet 11 can be opened according to the user's choice, and the driving motor 3 drives the air guide blade 2 to rotate. The air guide blade 2 can open the air outlet so that the air flow can flow through the air outlet 11.

[0060] At the same time, the rotation angle of the output shaft of the driving motor 3 can be adjusted according to the user's wind demand, thereby adjusting the rotation angle of the air guide blade 2. When the air guide blade 2 opens the air outlet 11 and the air guide blade 2 is parallel to the axis of the air outlet, the ventilation area of ​​the air outlet 11 is the largest and the air flow rate is the largest. When the user's wind demand is large, the air guide blade 2 rotates to a position parallel to the axis of the air outlet 11. When the user's wind demand is small, the air guide blade 2 can be adjusted between the position where the air guide blade 2 closes the air outlet 11 and the position where the air guide blade 2 is parallel to the axis of the air outlet 11. Among them, the driving motor 3 can realize the automation of the rotation of the air guide blade 2, and the driving motor 3 can better realize the independent rotation of the air guide blade 2, and it is convenient for the control of the air guide blade 2.

[0061] According to the air valve 10 of the embodiment of the utility model, a rotatable air guide blade 2 is arranged in the air outlet 11 of the installation frame 1 to open or close the air outlet 11, and the driving motor 3 is arranged outside the installation frame 1 and connected to the air guide blade 2 to drive the air guide blade 2 to rotate. When the air guide blade 2 opens the air outlet 11, the air guide blade 2 blocks the air outlet 11 less, so that the wind shielding area of ​​the air valve 10 can be smaller, and the air volume loss in the air handling device 100 can be reduced. In addition, the air valve 10 with one air guide blade 2 has a simple structure, which can improve the manufacturing efficiency of the air valve 10 and reduce the manufacturing cost of the air valve 10.

[0062] In some embodiments of the present invention, Figure 1 , Fig.17 and Fig.18 As shown, the rotation axis 24 line of the air guide blade 2 is located in the middle position of the air guide blade 2, so that when the air guide blade 2 switches to open or close the air outlet 11, it can rotate with the middle position of the air guide blade 2 as the axis. The pressure on both sides of the air guide blade 2 is relatively balanced, which can minimize the risk of deformation of the air guide blade 2 and make the rotation of the air guide blade 2 more stable.

[0063] Furthermore, if Figure 4 , Figure 8 and Fig.16 As shown, the air guide blade 2 includes a first half piece 21 and a second half piece 22 respectively located on both sides of the rotation axis 24 of the air guide blade 2, and a first limiting rib 111 and a second limiting rib 112 are provided on the inner peripheral wall of the air outlet 11. When the air guide blade 2 closes the air outlet 11, the first limiting rib 111 and the second limiting rib 112 are respectively located on the opposite sides of the air guide blade 2 along the axis direction of the air outlet 11 and are respectively suitable for abutting against the first half piece 21 and the second half piece 22.

[0064] It is understandable that if Figure 4 As shown, the two opposite sides of the air guide blade 2 along the axis direction of the air outlet 11 are the front side and the rear side respectively, the first limiting rib 111 is located at the front side of the air guide blade 2 along the axis direction of the air outlet 11, and the second limiting rib 112 is located at the rear side of the air guide blade 2 along the axis direction of the air outlet 11. When the air valve 10 closes the air outlet 11 and there is wind blowing from the front side to the rear side along the axis direction of the air outlet 11, the second limiting rib 112 abuts against the second half piece 22, which can prevent the airflow from blowing open the air guide blade 2, so that the sealing effect of the air valve 10 is better; when the air valve 10 closes the air outlet 11 and there is wind blowing from the rear side to the front side along the axis direction of the air outlet 11, the first limiting rib 111 abuts against the first half piece 21, which can prevent the airflow from blowing open the air guide blade 2, so that the sealing effect of the air valve 10 is better.

[0065] Furthermore, if Figure 4 and Figure 5 As shown, the first limiting rib 111 and the second limiting rib 112 include a connecting rib 1111 and a stop rib 1112. One end of the connecting rib 1111 is connected to the inner peripheral wall of the air outlet 11, and the other end extends toward the inside of the air outlet 11; the stop rib 1112 extends along the axial direction of the air outlet 11 and one end is connected to the end of the connecting rib 1111 away from the inner peripheral wall of the air outlet 11, and the end of the stop rib 1112 away from the connecting rib 1111 is suitable for abutting against the first half sheet 21 or the second half sheet 22. The circumferential edge of the air guide blade 2 is opposite to the middle position of the connecting rib 1111 of the first limiting rib 111 and the second limiting rib 112, so that when the air guide blade 2 rotates, the circumferential edge of the air guide blade 2 always maintains a certain distance from the inner wall of the mounting frame 1, which can avoid interference between the air guide blade 2 and the mounting frame 1, and does not affect the abutment between the stop rib 1112 and the first half piece 21 or the second half piece 22, thereby ensuring the sealing effect of the air valve 10.

[0066] Furthermore, if Figure 4 and Fig.17As shown, a first sealing rib 211 is provided at the edge of the first half piece 21, and the first sealing rib 211 extends toward the connecting rib 1111 of the first limiting rib 111. When the air guide blade 2 closes the air outlet 11, the first sealing rib 211 is located on the side of the stop rib 1112 of the first limiting rib 111 away from the center of the air outlet 11 and opposite to the connecting rib 1111; a second sealing rib 221 is provided at the edge of the second half piece 22, and the second sealing rib 221 extends toward the connecting rib 1111 of the second limiting rib 112. The second sealing rib 221 is located on the side of the stop rib 1112 of the second limiting rib 112 away from the center of the air outlet 11 and opposite to the connecting rib 1111. The stop rib 1112 of the first limiting rib 111 abuts against the first half piece 21, and the first sealing rib 211 is spaced apart from the connecting rib 1111, which can make the installation of the first half piece 21 more convenient. The stop rib 1112 of the second limiting rib 112 abuts against the second half piece 22, and the second sealing rib 221 is spaced apart from the connecting rib 1111, which can make the installation of the second half piece 22 more convenient.

[0067] The stop rib 1112 of the first limiting rib 111 abuts against the first half piece 21, and the first sealing rib 211 abuts against the connecting rib 1111, so that the sealing performance of the first half piece 21 is better; the stop rib 1112 of the second limiting rib 112 abuts against the second half piece 22, and the second sealing rib 221 abuts against the connecting rib 1111, so that the sealing performance of the second half piece 22 is better.

[0068] In addition, when the air guide blade 2 closes the air outlet 11 and the air flow flows along the axial direction of the air outlet 11, the air flow velocity is large and the pressure exerted by the air flow on the air guide blade 2 is large, the first sealing rib 211 or the second sealing rib 221 can stop against the mounting frame 1 to prevent the air guide blade 2 from causing large deformation.

[0069] Furthermore, if Figure 8 , Fig.14 and Fig.16 As shown, the first limiting rib 111 and the second limiting rib 112 extend along the circumferential direction of the air outlet 11, and the first sealing rib 211 and the second sealing rib 221 extend along the circumferential direction of the air guide blade 2. This ensures that the air guide blade 2 has a sealing effect with the mounting frame 1 in the circumferential direction, and the sealing effect of the air guide blade 2 is relatively reliable.

[0070] In some embodiments of the present invention, Figure 1 , Figure 3 , Fig.10 , Fig.12 and Fig.14As shown, the installation frame 1 includes a first half frame 12 and a second half frame 13, which are arranged and connected along the rotation axis 24 of the air guide blade 2 and jointly define the air outlet 11, which is convenient for the installation and removal of the air valve 10, and also convenient for the maintenance of the internal structure of the air valve 10. The opposite ends of the air guide blade 2 are rotatably arranged on the first half frame 12 and the second half frame 13, respectively, so that the installation of the air guide blade 2 can be more reliable, and the drive motor 3 is arranged on one of the first half frame 12 and the second half frame 13, and the position of the drive motor 3 is more reliable.

[0071] Furthermore, if Figure 8 , Fig. 9 and Fig.14 As shown, the first half frame 12 is provided with plug holes 121 at both ends perpendicular to the axis of the air guide blade 2, and the second half frame 13 is provided with plug buckles 131 that match the plug holes 121. At this time, the first half frame 12 and the second half frame 13 only need to be plugged together, and the assembly of the first half frame 12 and the second half frame 13 is relatively simple, which can improve the production efficiency of the air valve 10 and reduce the cost of the air valve 10.

[0072] Furthermore, if Fig.14 and Fig.15 As shown, the buckle 131 includes a first buckle 1311 and a second buckle 1312 that are spaced apart, an opening 1314 is provided between the first buckle 1311 and the second buckle 1312, a limiting protrusion 1313 is provided on the side of the first buckle 1311 and the second buckle 1312 that are away from each other, the first buckle 1311 and the second buckle 1312 are inserted into the insertion hole 121, and the limiting protrusion 1313 is stopped against the side of the part of the first half frame 12 that forms the insertion hole 121 away from the second half frame 13, which can avoid unreliable insertion of the insertion hole 121 and the buckle 131 as much as possible, and avoid gaps between the first half frame 12 and the second half frame 13 that cause air leakage of the air valve 10.

[0073] In some embodiments of the present invention, Figure 1 and Figure 7 As shown, the air valve 10 also includes a motor sealing box 4, and the motor sealing shell is arranged outside the drive motor 3. The motor sealing box 4 is connected to the mounting frame 1 and the drive motor 3, so that the outer cover of the drive motor 3 is provided with the motor sealing box 4, and the motor sealing box 4 can protect the drive motor 3 and prevent the drive motor 3 from being damaged by impact. The drive motor 3 is in a sealed state, which can reduce the contact between the drive motor 3 and the external environment and increase the service life of the drive motor 3. The motor sealing box 4 is provided with a threading hole 41 for the connection line 31 of the drive motor 3 to pass through. The drive motor 3 is powered by the connection line 31, so that the electrical connection of the drive motor 3 is more reliable.

[0074] In this embodiment, if Fig.10 and Fig.11As shown, one of the first half frame 12 and the second half frame 13 is provided with a lug 122, and the motor sealing box 4 is connected to the lug 122 via a fastener.

[0075] Furthermore, if Figure 1 and Figure 7 As shown, the air valve 10 further includes a sealing sheet 5, which is arranged in the motor sealing box 4 and located on the side of the drive motor 3 facing the threading hole 41, and the sealing sheet 5 has an avoidance hole 51 arranged opposite to the threading hole 41. The sealing sheet 5 can increase the sealing effect at the threading hole 41, prevent the drive motor 3 from being damp, improve the reliability of the air valve 10, and increase the service life of the drive motor 3.

[0076] In this embodiment, the sealing sheet 5 may be made of a flexible material such as sponge or rubber, so that the avoidance hole 51 on the sealing sheet 5 can wrap the connecting wire 31 of the driving motor 3 to increase the sealing effect of the driving motor 3 .

[0077] In some embodiments of the present invention, Fig.12 and Fig.13 As shown, a notch 14 is provided at one end of the mounting frame 1 along the axis direction of the air outlet 11. The notches 14 are multiple and spaced apart along the circumferential direction of the mounting frame 1. The notch 14 and the drive motor 3 are located on the same surface of the mounting frame 1. The connecting wire 31 of the drive motor 3 can be wound around the notch 14, which can prevent the connecting wire 31 from falling off when the drive motor 3 is working, and can prevent the connecting wire 31 from being entangled with the air valve 10 and other structures around the air valve 10, thereby improving the reliability of the operation of the air valve 10 structure.

[0078] In some embodiments of the present invention, Fig.17 and Fig.18 As shown, the opposite ends of the air guide blade 2 respectively have a motor shaft 23 and a rotating shaft 24, the motor shaft 23 and the rotating shaft 24 are rotatably arranged on the mounting frame 1, the motor shaft 23 has a non-circular hole 231 matched with the output shaft of the driving motor 3, and the rotating shaft 24 has a circular hole 241. The output shaft of the driving motor 3 cannot be installed in the motor shaft 23, which can avoid the wrong direction of the air guide blade 2, and can increase the reliability of the assembly of the air valve 10 structure.

[0079] The following describes a damper 10 according to a specific embodiment of the present invention with reference to the accompanying drawings. It is worth noting that the following description is only exemplary and intended to be used to explain the present invention, and cannot be construed as limiting the present invention.

[0080] like Figure 1 As shown, the air valve 10 according to the embodiment of the utility model includes a mounting frame 1, air guide blades 2, a driving motor 3, a motor sealing box 4 and a sealing sheet 5.

[0081] The installation frame 1 has an air vent 11 therein, and the air vent 11 is mainly used for air flow to pass through.

[0082] The installation frame 1 includes a first half frame 12 and a second half frame 13, which are arranged and connected along the rotation axis 24 of the air guide blade 2 and define the air outlet 11 together, which is convenient for the installation and removal of the air valve 10 and also convenient for the maintenance of the internal structure of the air valve 10. The opposite ends of the air guide blade 2 are rotatably arranged on the first half frame 12 and the second half frame 13, respectively, so that the installation of the air guide blade 2 can be more reliable. The drive motor 3 is arranged on one of the first half frame 12 and the second half frame 13, and the position of the drive motor 3 is more reliable. The first half frame 12 is provided with a plug hole 121 at both ends perpendicular to the axis of the air guide blade 2, and the second half frame 13 is provided with a buckle 131 that matches the plug hole 121. The first half frame 12 and the second half frame 13 only need to be plugged and assembled, and the assembly of the first half frame 12 and the second half frame 13 is relatively simple, which can improve the production efficiency of the air valve 10 and reduce the cost of the air valve 10.

[0083] The buckle 131 includes a first buckle 1311 and a second buckle 1312 that are spaced apart, an opening 1314 is provided between the first buckle 1311 and the second buckle 1312, a limiting protrusion 1313 is provided on the side of the first buckle 1311 and the second buckle 1312 that are away from each other, the first buckle 1311 and the second buckle 1312 are inserted into the insertion hole 121, and the limiting protrusion 1313 is stopped against the side of the part of the first half frame 12 that forms the insertion hole 121 away from the second half frame 13, which can avoid unreliable insertion of the insertion hole 121 and the buckle 131 as much as possible, and avoid gaps between the first half frame 12 and the second half frame 13 that cause air leakage of the air valve 10.

[0084] A notch 14 is provided at one end of the mounting frame 1 along the axis direction of the air outlet 11. The notches 14 are multiple and spaced apart along the circumferential direction of the mounting frame 1. The notch 14 and the drive motor 3 are located on the same surface of the mounting frame 1. The connecting wire 31 of the drive motor 3 can be wound around the notch 14, which can prevent the connecting wire 31 from falling off when the drive motor 3 is working, and can prevent the connecting wire 31 from being entangled with the air valve 10 and other structures around the air valve 10, thereby improving the reliability of the operation of the air valve 10 structure.

[0085] The air guide blade 2 is one and rotatably arranged in the air outlet 11, and is used to open or close the air outlet 11. When the air valve 10 is assembled, the assembly of a single air guide blade 2 is relatively simple, the overall structure of the air valve 10 is relatively simple, and the cost of the air valve 10 is relatively low. When the air guide blade 2 opens the air outlet 11, the air guide blade 2 has a smaller obstruction on the air outlet 11, which can make the windshield area of ​​the air valve 10 smaller, thereby reducing the air volume loss in the air treatment device 100.

[0086] The rotation axis 24 line of the air guide blade 2 is located at the middle position of the air guide blade 2, so that when the air guide blade 2 switches to open or close the air outlet 11, it can rotate with the middle position of the air guide blade 2 as the axis, and the pressure on both sides of the air guide blade 2 is relatively balanced, which can minimize the risk of deformation of the air guide blade 2 and make the rotation of the air guide blade 2 relatively stable. The air guide blade 2 includes a first half piece 21 and a second half piece 22 respectively located on both sides of the rotation axis 24 line of the air guide blade 2, and a first limiting rib 111 and a second limiting rib 112 are provided on the inner peripheral wall of the air outlet 11. When the air guide blade 2 closes the air outlet 11, the first limiting rib 111 and the second limiting rib 112 are respectively located on the opposite sides of the air guide blade 2 along the axis direction of the air outlet 11 and are suitable for abutting against the first half piece 21 and the second half piece 22.

[0087] The first limiting rib 111 and the second limiting rib 112 include a connecting rib 1111 and a stop rib 1112. One end of the connecting rib 1111 is connected to the inner peripheral wall of the air outlet 11, and the other end extends toward the inside of the air outlet 11; the stop rib 1112 extends along the axial direction of the air outlet 11 and one end is connected to the end of the connecting rib 1111 that is away from the inner peripheral wall of the air outlet 11, and the end of the stop rib 1112 that is away from the connecting rib 1111 is suitable for abutting against the first half piece 21 or the second half piece 22. The circumferential edge of the air guide blade 2 is opposite to the middle position of the connecting rib 1111 of the first limiting rib 111 and the second limiting rib 112, so that when the air guide blade 2 rotates, the circumferential edge of the air guide blade 2 always maintains a certain distance from the inner peripheral wall of the installation frame 1, which can avoid interference between the air guide blade 2 and the installation frame 1, and does not affect the abutment between the stop rib 1112 and the air guide blade 2, thereby ensuring the sealing effect of the air valve 10.

[0088] The edge of the first half piece 21 is provided with a first sealing rib 211 extending toward the connecting rib 1111 of the first limiting rib 111, and when the air guide blade 2 closes the air outlet 11, the first sealing rib 211 is located on the side of the stop rib 1112 of the first limiting rib 111 away from the center of the air outlet 11 and is separated from the connecting rib 1111; the edge of the second half piece 22 is provided with a second sealing rib 221 extending toward the connecting rib 1111 of the second limiting rib 112, and when the air guide blade 2 closes the air outlet 11, the second sealing rib 221 is located on the side of the stop rib 1112 of the second limiting rib 112 away from the center of the air outlet 11 and is separated from the connecting rib 1111. The stop rib 1112 of the first limiting rib 111 abuts against the first half piece 21, and the first sealing rib 211 is spaced apart from the connecting rib 1111, so that the installation of the first half piece 21 is more convenient. The stop rib 1112 of the second limiting rib 112 abuts against the second half piece 22, and the second sealing rib 221 is spaced apart from the connecting rib 1111, so that the installation of the second half piece 22 is more convenient. The first limiting rib 111 and the second limiting rib 112 extend along the circumferential direction of the air outlet 11, and the first sealing rib 211 and the second sealing rib 221 extend along the circumferential direction of the air guide blade 2. The air guide blade 2 has a sealing effect with the installation frame 1 in the circumferential direction, so that the sealing effect of the air guide blade 2 is more reliable.

[0089] The opposite ends of the air guide blade 2 are provided with a motor shaft 23 and a rotating shaft 24, respectively. The motor shaft 23 and the rotating shaft 24 are rotatably arranged on the mounting frame 1. The motor shaft 23 has a non-circular hole 231 matched with the output shaft of the driving motor 3, and the rotating shaft 24 has a circular hole 241. The output shaft of the driving motor 3 cannot be installed in the motor shaft 23, which can avoid the wrong direction of the air guide blade 2, and can increase the reliability of the assembly of the air valve 10 structure.

[0090] The driving motor 3 is arranged outside the mounting frame 1 and connected to the wind guide blade 2, and is used to drive the wind guide blade 2 to rotate. One end of the wind guide blade 2 is connected to the output shaft of the driving motor 3, and the driving motor 3 can provide driving force for the wind guide blade 2.

[0091] The air valve 10 can be used in the air treatment device 100. When the air treatment device 100 is closed, the air guide blade 2 can close the air outlet 11, and the sealing effect inside the air treatment device 100 is better. After the air treatment device 100 is turned on, the air outlet 11 can be opened according to the user's choice, and the driving motor 3 drives the air guide blade 2 to rotate. The air guide blade 2 can open the air outlet so that the air flow can flow through the air outlet 11.

[0092] At the same time, the rotation angle of the output shaft of the driving motor 3 can be adjusted according to the user's wind demand, thereby adjusting the rotation angle of the air guide blade 2. When the air guide blade 2 opens the air outlet 11 and the air guide blade 2 is parallel to the axis of the air outlet, the ventilation area of ​​the air outlet 11 is the largest and the air flow rate is the largest. When the user's wind demand is large, the air guide blade 2 rotates to a position parallel to the axis of the air outlet 11. When the user's wind demand is small, the air guide blade 2 can be adjusted between the position where the air guide blade 2 closes the air outlet 11 and the position where the air guide blade 2 is parallel to the axis of the air outlet 11. Among them, the driving motor 3 can realize the automation of the rotation of the air guide blade 2, and the driving motor 3 can better realize the independent rotation of the air guide blade 2, and it is convenient for the control of the air guide blade 2.

[0093] The air valve 10 also includes a motor sealing box 4. The motor sealing shell is arranged outside the drive motor 3. The motor sealing box 4 is connected to the mounting frame 1 and the drive motor 3, so that the outer cover of the drive motor 3 is provided with the motor sealing box 4. The motor sealing box 4 can protect the drive motor 3 and prevent the drive motor 3 from being damaged by impact. The drive motor 3 is in a sealed state, which can reduce the contact between the drive motor 3 and the external environment and increase the service life of the drive motor 3. The motor sealing box 4 is provided with a threading hole 41 for the connecting wire 31 of the drive motor 3 to pass through. The drive motor 3 is powered by the connecting wire 31, so that the electrical connection of the drive motor 3 is more reliable.

[0094] The air valve 10 further includes a sealing sheet 5, which is disposed in the motor sealing box 4 and is located on the side of the drive motor 3 facing the threading hole 41. The sealing sheet 5 has an avoidance hole 51 disposed opposite to the threading hole 41. The sealing sheet 5 can increase the sealing effect at the threading hole 41, prevent the drive motor 3 from being damp, improve the reliability of the air valve 10, and increase the service life of the drive motor 3.

[0097] like Fig.19 and Fig. 20As shown, the indoor air inlet 205 and the indoor air outlet 203 are both connected to the indoor room, and the outdoor air inlet 202 and the outdoor air outlet 206 are both connected to the outdoor room.

[0098] like Fig.19 As shown, the shell 20 is formed as a rectangular parallelepiped, the indoor exhaust duct 204 and the fresh air duct 201 can be arranged side by side in a roughly horizontal direction, the indoor exhaust duct 204 and the fresh air duct 201 can both extend roughly in a horizontal direction, the indoor air inlet 205, the indoor air outlet 203, the outdoor air inlet 202 and the outdoor air outlet 206 can all be formed on the circumferential side wall of the shell 20, the indoor air inlet 205 and the indoor air outlet 203 can be located on the same side of the shell 20, the outdoor air inlet 202 and the outdoor air outlet 206 can be located on the same side of the shell 20, the indoor air inlet 205 and the outdoor air outlet 206 can be located on the opposite sides of the shell 20, and the indoor air outlet 203 and the outdoor air inlet 202 can be located on opposite sides of the shell 20.

[0099] Furthermore, the shell 20 includes a top cover, a bottom plate and side panels located between the top cover and the bottom plate, the side panels include a left side panel, a right side panel, a front side panel and a rear side panel, the left side panel, the front side panel, the right side panel and the rear side panel are connected end to end in sequence, the upper ends of the left side panel, the right side panel, the front side panel and the rear side panel are connected to the top cover, the lower ends of the left side panel, the right side panel, the front side panel and the rear side panel are connected to the bottom plate, the indoor air inlet 205 and the indoor air outlet 203 are arranged on the right side panel, and the outdoor air inlet 202 and the outdoor air outlet 206 are arranged on the left side panel.

[0100] like Fig.19 As shown, the fresh air fan 208 and the first heat exchange module are both arranged in the fresh air duct 201. The fresh air fan 208 and the first heat exchange module can be arranged in the fresh air duct 201 along the flow direction of the airflow in the fresh air duct 201. For example, along the flow direction of the airflow in the fresh air duct 201, the fresh air fan 208 can be arranged on the downstream side of the first heat exchange module. For example, the first heat exchange module can be adjacent to the outdoor air inlet 202, and the fresh air fan 208 can be adjacent to the indoor air outlet 203. The exhaust fan 209 and the second heat exchange module are both arranged in the indoor exhaust duct 204. The exhaust fan 209 and the second heat exchange module can be arranged in the indoor exhaust duct 204 along the flow direction of the airflow in the indoor exhaust duct 204. For example, along the flow direction of the airflow in the indoor exhaust duct 204, the exhaust fan 209 can be arranged on the upstream side of the second heat exchange module. For example, the second heat exchange module can be adjacent to the outdoor air outlet 206, and the exhaust fan 209 can be adjacent to the indoor air inlet 205.

[0101] When the air handling equipment is in cooling operation, at least one heat exchanger in the first heat exchange module operates as an evaporator, and the fresh air fan 208 operates to drive outdoor fresh air from the outdoor air inlet 202 into the fresh air duct 201. The outdoor air entering the fresh air duct 201 can exchange heat with the first heat exchange module, and the outdoor air after heat exchange is discharged to the room through the indoor air outlet 203, so that the outdoor fresh air can be introduced into the room to improve the indoor air quality.

At the same time, at least one heat exchanger in the second heat exchange module operates as a condenser, and the exhaust fan 209 operates to drive the not-so-fresh air in the room from the indoor air inlet 205 into the indoor exhaust duct 204. The indoor air entering the indoor exhaust duct 204 can exchange heat with the second heat exchange module for heat recovery, and the indoor air after heat exchange is discharged to the outside through the outdoor air outlet 206, so that the not-so-fresh air in the room can be discharged to the outside to improve the indoor air quality.

[0102] like Fig.19 As shown, the exhaust fan 209 is disposed in the exhaust duct 204. The exhaust fan 209 is isolated from the fresh air fan 208 in the fresh air duct 201 to prevent the exhaust fan 209 from sucking in the air flow in the fresh air duct 201 and the air flow outside the housing 20, or the air flow discharged by the exhaust fan 209 flows into the fresh air duct 201.

[0103] When the fresh air duct 201 and the exhaust air duct 204 need to be connected, the air mixing port 207 is opened, and the fresh air duct 201 and the exhaust air duct 204 are connected.
