[0051] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0052] like Figures 1 to 10As shown, the fresh air module 100 of this embodiment includes a housing 1, a duct 2, and a fan 3. The duct 2 is connected to the housing 1, and the fan 3 is disposed inside the housing 1. The housing 1 is provided with an exhaust inlet 11 and a fresh air outlet 12, and the fan 3 is provided with a fan inlet 3121 and a fan outlet 3111. At least a portion of the fan 3 is rotatable relative to the housing 1 to switch between exhaust mode and fresh air mode. The fan outlet 3111 is selectively connected to the duct 2 and the fresh air outlet 12. In exhaust mode, the fan inlet 3121 is connected to the exhaust inlet 11, and the fan outlet 3111 is connected to the duct 2. In fresh air mode, the fan inlet 3121 is connected to the duct 2, and the fan outlet 3111 is connected to the fresh air outlet 12.

[0053] In the exhaust mode of the fresh air module 100 of this embodiment, at least a portion of the fan 3 rotates relative to the housing 1, causing the fresh air module 100 to be in exhaust mode, such as... Figure 7 and Figure 8 As shown, the fan inlet 3121 is connected to the exhaust inlet 11, and the fan outlet 3111 is connected to the duct 2. At this time, driven by the fan 3, the indoor airflow enters the housing 1 through the exhaust inlet 11, then sequentially passes through the fan inlet 3121 and the fan outlet 3111, and is discharged to the outside through the duct 2. In fresh air mode, at least a portion of the fan 3 rotates relative to the housing 1, causing the fresh air module 100 to be in fresh air mode, as shown... Figure 9 and Figure 10 As shown, the fan inlet 3121 is connected to the duct 2, and the fan outlet 3111 is connected to the fresh air outlet 12. At this time, driven by the fan 3, outdoor airflow enters the housing 1 through the duct 2, then sequentially passes through the fan inlet 3121 and the fan outlet 3111, and is discharged into the room from the fresh air outlet 12. The fresh air module 100 of this embodiment can switch between exhaust and fresh air modes by rotating at least a portion of the fan 3 relative to the housing 1, effectively simplifying the switching structure of the fresh air module 100 and reducing its cost.

[0054] Optionally, such as Figures 1 to 3 As shown, the exhaust inlet 11 and the fresh air outlet 12 are located on different sides of the housing 1.

[0055] For example, the exhaust inlet 11 is located on the lower side of the housing 1, and the fresh air outlet 12 is located on the front side of the housing 1.

[0056] By placing the exhaust inlet 11 and the fresh air outlet 12 on different sides of the housing 1, it is convenient to set the orientation of the exhaust inlet 11 and the fresh air outlet 12 as needed, thereby facilitating the installation of the fresh air module 100.

[0057] Optionally, such as Figures 1 to 3 As shown, the exhaust inlet 11 and the duct 2 are located on different sides of the housing 1.

[0058] For example, the air duct 2 is located on the left side of the housing 1, and the exhaust inlet 11 is located on the lower side of the housing 1.

[0059] When the fresh air module 100 is in use, the duct 2 needs to be connected to the outside and the exhaust inlet 11 needs to be connected to the inside. By setting the exhaust inlet 11 and the duct 2 on different sides of the housing 1, it is convenient to set the orientation of the exhaust inlet 11 and the duct 2 as needed, thereby facilitating the installation of the fresh air module 100.

[0060] Optionally, the fresh air outlet 12 and the air duct 2 are located on different sides of the housing 1.

[0061] For example, the air duct 2 is located on the left side of the housing 1, and the fresh air outlet 12 is located on the front side of the housing 1.

[0062] When the fresh air module 100 is in use, the duct 2 needs to be connected to the outside and the exhaust inlet 11 needs to be connected to the inside. By setting the exhaust inlet 11 and the duct 2 on different sides of the housing 1, it is convenient to set the orientation of the exhaust inlet 11 and the duct 2 as needed, thereby facilitating the installation of the fresh air module 100.

[0063] Optionally, such as Figures 5 to 7 , Figure 9 As shown, the fresh air module 100 includes a first damper 4, which is movably connected to the housing 1 to open and close the exhaust inlet 11. In exhaust mode, the first damper 4 opens the exhaust inlet 11, allowing the fan inlet 3121 to communicate with the exhaust inlet 11. In fresh air mode, the first damper 4 closes the exhaust inlet 11, cutting off the connection between the fan inlet 3121 and the exhaust inlet 11.

[0064] In exhaust mode, the first damper 4 opens the exhaust inlet 11, connecting the fan inlet 3121 with the exhaust inlet 11, allowing indoor airflow to enter the interior of the casing 1 through the exhaust inlet 11 and then enter the fan 3 through the fan inlet 3121. In fresh air mode, the first damper 4 closes the exhaust inlet 11, cutting off the connection between the fan inlet 3121 and the exhaust inlet 11. At this time, the fan inlet 3121 connects with the duct 2, allowing outdoor airflow to enter the interior of the casing 1 through the duct 2 and then enter the fan 3 through the fan inlet 3121.

[0065] By setting the first damper 4, when switching between exhaust mode and fresh air mode, the exhaust inlet 11 can be opened and closed by the first damper 4, so that the duct 2 can be connected to one of the fan inlet 3121 and the fan outlet 3111. This helps to further simplify the structure of the fresh air module 100 and further reduce the cost of the fresh air module 100.

[0066] Optionally, the first damper 4 is rotatably connected to the housing 1.

[0067] For example, the first damper 4 is rotatably connected to the housing 1 via a rotating shaft.

[0068] The first air damper 4 is rotatably connected to the housing 1. By rotating the first air damper 4, the exhaust air inlet 11 can be opened and closed, which helps to further simplify the structure of the fresh air module 100 and further reduce the cost of the fresh air module 100.

[0069] Optionally, the fresh air module 100 also includes a first motor 41, which drives the first damper 4 to rotate.

[0070] By setting a first motor 41, the first damper 4 is driven to rotate, thereby opening and closing the exhaust inlet 11.

[0071] In some embodiments, such as Figure 5 , Figure 7 and Figure 9 As shown, the housing 1 contains a first chamber 16, a second chamber 17, and a second damper 5. The duct 2 communicates with the first chamber 16, and the fan inlet 3121 communicates with the second chamber 17. The second damper 5 is movably connected to the housing 1 to allow the first chamber 16 and the second chamber 17 to communicate and close. In exhaust mode, the first chamber 16 and the second chamber 17 are closed, thus closing the connection between the fan inlet 3121 and the duct 2; in fresh air mode, the first chamber 16 and the second chamber 17 are connected, thus connecting the fan inlet 3121 and the duct 2.

[0072] In exhaust mode, the first chamber 16 and the second chamber 17 are closed, thus cutting off the connection between the fan inlet 3121 and the duct 2, preventing outdoor airflow from entering the fan inlet 3121 through the duct 2. In fresh air mode, the first chamber 16 and the second chamber 17 are connected, thus connecting the fan inlet 3121 and the duct 2, allowing outdoor airflow to enter the fan inlet 3121 through the duct 2.

[0073] By designing the housing 1 as described above and setting the second damper 5 inside the housing 1, it is convenient to connect and disconnect the air duct 2 and the fan inlet 3121, which helps to further simplify the structure of the fresh air module 100 and further reduce the cost of the fresh air module 100.

[0074] Optionally, the first damper 4 opens and closes the exhaust inlet 11, so that the second chamber 17 can be selectively connected to and disconnected from the exhaust inlet 11.

[0075] In exhaust mode, the first chamber 16 and the second chamber 17 are closed, and the first damper 4 opens the exhaust inlet 11, thereby closing the gap between the fan inlet 3121 and the duct 2, and connecting the fan inlet 3121 and the exhaust inlet 11. At this time, the airflow in the room enters the second chamber 17 through the exhaust inlet 11, then enters the fan 3 through the fan inlet 3121, and finally is discharged to the outside through the fan outlet 3111 and the duct 2.

[0076] In fresh air mode, the first chamber 16 and the second chamber 17 are connected, and the first damper 4 closes the exhaust inlet 11, thereby connecting the fan inlet 3121 to the duct 2 and cutting off the connection between the fan inlet 3121 and the exhaust inlet 11. At this time, outdoor airflow passes through the duct 2, the first chamber 16 and the second chamber 17, and enters the fan 3 through the fan inlet 3121, and is then discharged into the room through the fan outlet 3111 and the fresh air outlet 12.

[0077] Optionally, the housing 1 is provided with a partition 18, which separates the first chamber 16 and the second chamber 17. The partition 18 has a communication port 3122, and the second damper 5 is used to open and close the communication port 3122 to connect and disconnect the first chamber 16 and the second chamber 17. In exhaust mode, the second damper 5 closes the communication port 3122 to disconnect the first chamber 16 and the second chamber 17; in fresh air mode, the second damper 5 opens the communication port 3122 to connect the first chamber 16 and the second chamber 17.

[0078] By using the second damper 5 to open and close the connection port 3122, the first chamber 16 and the second chamber 17 can be cut off and connected, which helps to further simplify the structure of the fresh air module 100 and further reduce the cost of the fresh air module 100.

[0079] Optionally, the second damper 5 is rotatably connected to the partition 18.

[0080] For example, the second damper 5 is rotatably connected to the partition 18 via a rotating shaft.

[0081] The second air damper 5 is rotatably connected to the partition 18. By rotating the second air damper 5, the connection port 3122 can be opened and closed, which helps to further simplify the structure of the fresh air module 100 and further reduce the cost of the fresh air module 100.

[0082] Optionally, the fresh air module 100 also includes a second motor 42, which drives the second damper 5 to rotate.

[0083] By setting a second motor 42, the second damper 5 is driven to rotate, thereby opening and closing the connection port 3122.

[0084] Optionally, such as Figure 6 , Figure 8 and Figure 10 As shown, the fan 3 includes a fan housing 31, which includes a volute 311 and a pressure cover 312. The volute 311 is rotatable relative to the housing 1, and the pressure cover 312 is connected to the housing 1. The fan inlet 3121 and the connecting port 3122 are both located on the pressure cover 312. A part of the pressure cover 312 blocks the opening of the volute 311 and forms the fan outlet 3111 with the volute 311. The other part of the pressure cover 312 forms a partition 18.

[0085] When the fresh air module 100 is working, the volute 311 rotates relative to the housing 1 to switch between exhaust mode and fresh air mode, while the cover 312 is fixed relative to the housing 1.

[0086] By sealing the opening of the volute 311 with a portion of the cap 312 and forming a partition 18 with another portion of the cap 312, the cap 312 is used not only as part of the fan housing 31 but also as a partition 18, which helps to further simplify the structure of the fresh air module 100 and reduce the cost of the fresh air module 100.

[0087] Optionally, such as Figure 5 , Figure 7 and Figure 9 As shown, the fan 3 includes an impeller 32 and an impeller motor 33. The impeller motor 33 is connected to the volute 311, and the impeller 32 is connected to the impeller motor 33 in a transmission connection. The impeller motor 33 is used to drive the impeller 32 to rotate.

[0088] The impeller motor 33 can be fixed to the volute 311 by a motor cover, and the motor cover and the volute 311 can be connected by screws; the impeller 32 is connected to the motor shaft of the impeller motor 33.

[0089] By connecting the impeller 32 and the impeller motor 33 to the volute 311, it is convenient to install and fix the impeller 32 and the impeller motor 33.

[0090] like Figure 8 As shown, the fan 3 also includes a guide ring 34, which is located at the fan inlet 3121.

[0091] By setting a guide ring 34 at the fan inlet 3121, the airflow inside the housing 1 can be guided so that the airflow inside the housing 1 enters the fan 3 through the fan inlet 3121, thereby increasing the air volume of the fresh air module 100.

[0092] Optionally, the housing 1 is provided with a drive device 7, which is used to drive at least a portion of the fan 3 to rotate.

[0093] For example, the drive unit 7 is used to drive the volute 311 to rotate.

[0094] By setting up the drive device 7, it is convenient to realize the rotation of at least a part of the fan 3, which helps to improve the user experience.

[0095] In other embodiments, the fan housing 31 may also rotate entirely relative to the housing 1, that is, both the volute 311 and the pressure cap 312 rotate relative to the housing 1.

[0096] Optionally, the driving device 7 is a drive motor, and the first motor 41, the second motor 42 and the driving device 7 are all stepper motors.

[0097] Optionally, such as Figure 7 and Figure 9 As shown, the housing 1 includes a mounting plate 1011, a drive device 7 is disposed between the mounting plate 1011 and the fan 3, the drive device 7 is connected to the mounting plate 1011, and the drive device 7 is connected to the fan 3 in a transmission connection.

[0098] The drive unit 7 can be fixed to the mounting plate 1011 by a motor cover, and the motor cover and the mounting plate 1011 can be connected by screws; the fan 3 is connected to the motor shaft of the mounting plate 1011.

[0099] By placing the drive unit 7 between the mounting plate 1011 and the fan 3, it is convenient to install and fix the drive unit 7.

[0100] Optionally, the housing 1 includes a bottom shell 101 and a cover plate 102. The cover plate 102 is connected to the bottom shell 101 and forms a cavity, and the fan 3 is disposed in the cavity. The bottom shell 101 includes a bottom plate and a side plate 1012, which form an open cavity. The cover plate 102 seals the opening of the cavity.

[0101] The base plate forms the aforementioned mounting plate 1011, the exhaust inlet 11 is located on the cover plate 102, and the fresh air outlet 12 and the air duct outlet 13 are located on different side plates 1012.

[0102] In some embodiments, such as Figure 8 As shown, the housing 1 is provided with an air duct outlet 13, and the air duct 2 is connected to the air duct outlet 13. In the exhaust mode, the fan outlet 3111 corresponds to the air duct outlet 13, so that the fan outlet 3111 is connected to the air duct 2.

[0103] By aligning the fan outlet 3111 with the duct outlet 13 in the exhaust mode, it is easy to connect the fan outlet 3111 with the duct 2, which helps to further simplify the structure of the fresh air module 100 and reduce the cost of the fresh air module 100.

[0104] Optionally, such as Figure 8 As shown, the housing 1 is provided with an exhaust duct 14, one end of which is connected to the air duct 2. In exhaust mode, the fan outlet 3111 abuts against the other end of the exhaust duct 14.

[0105] By setting an exhaust duct 14 inside the housing 1, in exhaust mode, the fan outlet 3111 abuts against the other end of the exhaust duct 14, which facilitates the sealing between the fan outlet 3111 and the duct 2, reduces the risk of air leakage in the fresh air module 100, and helps to improve the air volume and reliability of the fresh air module 100.

[0106] Optionally, such as Figure 10 As shown, in fresh air mode, fan outlet 3111 corresponds to fresh air outlet 12, so that fan outlet 3111 and fresh air outlet 12 are connected.

[0107] In the fresh air mode, the fan outlet 3111 corresponds to the fresh air outlet 12, which facilitates the connection between the fan outlet 3111 and the fresh air outlet 12, and helps to further simplify the structure of the fresh air module 100 and reduce the cost of the fresh air module 100.

[0108] Optionally, such as Figure 10 As shown, a fresh air duct 15 is provided inside the housing 1, and one end of the fresh air duct 15 is connected to the fresh air outlet 12. In fresh air mode, the fan outlet 3111 abuts against the other end of the fresh air duct 15.

[0109] By setting a fresh air duct 15 inside the housing 1, in fresh air mode, the fan outlet 3111 abuts against the other end of the fresh air duct 15, which facilitates the sealing between the fan outlet 3111 and the fresh air outlet 12, reduces the risk of air leakage in the fresh air module 100, and helps to improve the air volume and reliability of the fresh air module 100.

[0110] In some embodiments, such as Figure 5 , Figure 7 and Figure 9 As shown, the fresh air module 100 includes a filter device 6, which is disposed between the duct 2 and the housing 1. The filter device 6 is used to filter the airflow flowing from the duct 2 into the housing 1.

[0111] By setting up a filter device 6, the airflow flowing from the duct 2 into the housing 1 can be filtered, thereby improving the quality of the airflow entering the housing 1, thus improving the quality of the airflow entering the room and enhancing the user experience of the fresh air module 100.

[0112] Optionally, the filter device 6 is located on the outside of the housing 1 and connected to the air duct 2.

[0113] By placing the filter device 6 on the outside of the housing 1, it is convenient to clean or replace the filter device 6, which helps to reduce the maintenance cost of the fresh air module 100.
