[0039] First, as Figures 1 - 6 shown, the fresh air module 100 includes a fan component 1, a first air duct component 2, a second air duct component 3, and an air direction control assembly 4. The fan component 1 includes a driving motor 11 and a wind wheel 12. The driving motor 11 is power-connected to the wind wheel 12 and is used to drive the wind wheel 12 to rotate. The fan component 1 has a fan inlet 13 and a fan outlet 14. When the driving motor 11 drives the wind wheel 12 to rotate, the wind wheel 12 can suck in air flow from the fan outlet 14 and blow out the air flow through the fan outlet 14.

[0040] The first air duct component 2 has a first air duct cavity 21 and an air supply port 22. The air supply port 22 is communicated with the indoor space. The first air duct component 2 can cooperate with the fan component 1 so that the first air duct cavity 21 can be communicated with the fan outlet 14. The fan component 1 can send the air flow into the first air duct cavity 21 so that the air flow can flow along the first air duct cavity 21 and blow out to the indoor space from the air supply port 22.

[0041] It should be noted that the air supply port 22 can be set to one; or, the air supply port 22 can be set to multiple. The orientations of the multiple air supply ports 22 can be the same, for example, the multiple air supply ports 22 are all located on the front side of the fresh air module 100, or the orientations of the multiple air supply ports 22 can be different, for example, the multiple air supply ports 22 are respectively located on the left and right sides of the fresh air module 100. The present invention does not limit this.

[0042] The second air duct component 3 has a second air duct cavity 33, an exhaust air cavity 34, a communication cavity 35, an air inlet 311 and a fresh air inlet 321. The air inlet 311 communicates with the indoor space, and the fresh air inlet 321 communicates with the outdoor space. The communication cavity 35 communicates with the exhaust air cavity 34 and the fresh air inlet 321 respectively. The second air duct component 3 can cooperate with the fan component 1 so that the second air duct cavity 33 can communicate with the fan inlet 13, and the second air duct component 3 can also cooperate with the first air duct component 2 so that the exhaust air cavity 34 can communicate with the first air duct cavity 21.

[0043] The wind direction regulation component 4 includes a first valve component 41 and a second valve component 42. The first valve component 41 is installed in the first air duct component 2. The first valve component 41 is used to communicate the first air duct cavity 21 with the air supply outlet 22 or the exhaust air cavity 34 to regulate the air flow from the first air duct cavity 21 to one of the air supply outlet 22 and the exhaust air cavity 34. The second valve component 42 is installed in the second air duct component 3. The second valve component 42 is used to communicate the second air duct cavity 33 with the air inlet 311 or the communication cavity 35 to regulate the air intake of the second air duct cavity 33 from one of the air inlet 311 and the communication cavity 35.

[0044] Specifically, as Figures 3 - 4 shown, the air conditioner 1000 has a fresh air mode and an exhaust air mode. When the air conditioner 1000 is in the fresh air mode, the first valve component 41 can communicate the first air duct cavity 21 with the air supply outlet 22, and the second valve component 42 can communicate the second air duct cavity 33 with the communication cavity 35. With the operation of the fan component 1, the fresh air flow can flow into the communication cavity 35 through the fresh air inlet 321, and flow through the second air duct cavity 33 to flow into the fan inlet 13. Then, the fan component 1 can blow the fresh air flow into the first air duct cavity 21 through the fan outlet 14. The fresh air flow can flow along the first air duct cavity 21 and be blown into the indoor space through the air supply outlet 22.

[0045] As Figures 5 - 6 shown, when the air conditioner 1000 is in the exhaust air mode, the first valve component 41 can communicate the first air duct cavity 21 with the exhaust air cavity 34, and the second valve component 42 can communicate the second air duct cavity 33 with the air inlet 311. With the operation of the fan component 1, the indoor air flow can flow into the second air duct cavity 33 through the air inlet 311. The indoor air flow can flow through the second air duct cavity 33 to flow into the fan inlet 13. Then, the fan component 1 can blow the fresh air flow into the first air duct cavity 21 through the fan outlet 14. The fresh air flow can flow through the first air duct cavity 21, the exhaust air cavity 34 and the communication cavity 35 in sequence, and be blown out to the outdoor space through the fresh air inlet 321. Thus, two-way ventilation can be achieved, which is beneficial to improving the air quality of the indoor space.

[0046] According to the fresh air module 100 of the embodiments of the present utility model, the fresh air inlet 321 can be connected to the air supply outlet 22 through the air direction control assembly 4, so that the fresh air flow can be blown into the indoor space through the air supply outlet 22, and the air inlet 311 can be connected to the fresh air inlet 321 through the air direction control assembly 4, so that the indoor air can be blown out to the outdoor space through the fresh air inlet 321, thereby realizing the two-way ventilation function. Moreover, the structure of the fresh air module 100 is simple, each part can independently define the corresponding air duct, which is easy to process and assemble, and is beneficial to improving the practicability of the fresh air module 100.

[0047] In some embodiments of the present utility model, the second air duct component 3 includes: a first air duct member 31 and a second air duct member 32. The first air duct member 31 is respectively matched with the fan component 1 and the first air duct component 2. A part of the second air duct cavity 33 and the exhaust air cavity 34 are formed in the first air duct member 31, and the air inlet 311 is arranged on the first air duct member 31; the second air duct member 32 is assembled and connected with the first air duct member 31, the communication cavity 35 and the remaining part of the exhaust air cavity 34 are formed in the second air duct member 32, and the fresh air inlet 321 is arranged on the second air duct member 32.

[0048] For example, with reference to Figure 2 、 Figure 3 and Figure 7 shown, the second air duct component 3 includes a first air duct member 31 and a second air duct member 32. The first air duct member 31 and the second air duct member 32 are integrally formed. A part of the second air duct cavity 33 and the exhaust air cavity 34 are formed in the first air duct member 31. The first air duct member 31 is used to cooperate with the fan component 1 so that the second air duct cavity 33 can be connected to the fan inlet 13, and the first air duct member 31 can also cooperate with the first air duct component 2 so that the first air duct cavity 21 can be connected to the exhaust air cavity 34. The air inlet 311 is also arranged on the first air duct member 31, and the air inlet 311 is connected to the second air duct cavity 33.

[0049] At the same time, a communication cavity 35 and the remaining part of the exhaust air cavity 34 are formed in the second air duct member 32. The second air duct member 32 is used to be assembled and connected with the first air duct member 31, so that the communication cavity 35 can be connected to the second air duct cavity 33, and the first air duct member 31 and the second air duct member 32 can jointly define the exhaust air cavity 34. The fresh air inlet 321 is also arranged on the first air duct member 31, and the fresh air inlet 321 is connected to the exhaust air cavity 34 through the communication cavity 35.

[0050] Through the above settings, the forming difficulty of the second air duct component 3 can be reduced, which is beneficial to reducing the processing cost of the second air duct component 3 and improving the practicability of the fresh air module 100.

[0051] In some embodiments of the present utility model, such as Figure 1 and Figure 3As shown, the fan component 1 is assembled on the front side of the first air duct component 31 , the first air duct component 2 is assembled above the first air duct component 31 , the second air duct component 32 is assembled on the rear side of the first air duct component 31 , and the fresh air outlet 321 is arranged at the rear end of the second air duct component 32 .

[0052] Through the above-mentioned arrangement, the structure of the fresh air module 100 can be made compact, which is beneficial to shortening the flow path and reducing the flow resistance, and the fan component 1 can be directly opposite the fresh air outlet 321 in the front-to-back direction, which can further reduce the flow resistance of the fresh air flow, increase the flow rate of the fresh air flow, and improve the design rationality of the fresh air module 100.

[0053] In some embodiments of the present invention, Figure 7 As shown, the second air duct member 32 is formed with a joint structure 322 at the fresh air outlet 321, and the joint structure 322 is used to connect with the fresh air pipe. For example, the joint structure 322 can be connected to the fresh air pipe by clamping; or the joint structure 322 can be connected to the fresh air pipe by screwing; or the joint structure 322 can be connected to the fresh air pipe by fasteners, and the present invention does not limit this.

[0054] Through the above-mentioned arrangement, the fresh air outlet 321 can be connected to the outdoor space through the fresh air pipe, which reduces the difficulty of connecting the fresh air module 100 with the outdoor space. In addition, the installation difficulty of the fresh air pipe is low and the installation stability is good, which improves the reliability of the fresh air module 100.

[0055] In some embodiments of the present invention, the second valve assembly 42 includes: an air inlet valve 421 and a fresh air valve 422. The air inlet valve 421 is installed on the first air duct member 31 and is used to switch the air inlet 311; the fresh air valve 422 is installed on the first air duct member 31 and is located at the matching position of the first air duct member 31 and the second air duct member 32, so as to switch the connection and disconnection of the connecting cavity 35 and the second air duct cavity 33.

[0056] For example, refer to Figures 2 - 6 As shown, the second valve assembly 42 includes an air inlet valve 421 and a fresh air valve 422. The air inlet valve 421 is installed on the first air duct member 31 and is located at the air inlet 311. The air inlet valve 421 is used to switch the air inlet 311, such as opening or closing the air inlet 311. The fresh air valve 422 is installed on the first air duct member 31 and is located at the matching position of the first air duct member 31 and the second air duct member 32. The fresh air valve 422 is used to switch the connection and disconnection of the connecting cavity 35 and the second air duct cavity 33, such as connecting or disconnecting the connecting cavity 35 and the second air duct cavity 33.

[0057] Specifically, if Figures 3 - 4As shown, when the air conditioner 1000 is in the fresh air mode, the intake valve 421 can close the air intake 311, and the fresh air valve 422 can connect the communication cavity 35 with the second air duct cavity 33, so that the second air duct cavity 33 can intake air from the fresh air inlet 321; as Figures 5 - 6 shown, when the air conditioner 1000 is in the exhaust mode, the intake valve 421 can open the air intake 311, and the fresh air valve 422 can disconnect the communication cavity 35 from the second air duct cavity 33, so that the second air duct cavity 33 can intake air from the air intake 311.

[0058] Through the above settings, the air intake of the second air duct cavity 33 from the fresh air inlet 321 or from the air intake 311 can be controlled more accurately, realizing the stable switching of the fresh air module 100 between the fresh air mode and the exhaust mode, and improving the practicability of the fresh air module 100.

[0059] In some embodiments of the present invention, as Figures 2 - 3 shown, the fresh air module 100 of the embodiment of the present invention further includes: a first purification member 5, and the first purification member 5 is arranged between the first air duct member 31 and the fan component 1 to be downstream of the intake valve 421 and the fresh air valve 422.

[0060] It can be understood that by arranging the first purification member 5, the air flow flowing to the fan component 1 can be filtered and purified to prevent large particle impurities in the air flow from affecting the normal operation of the fan component 1, and the first purification member 5 can improve the fresh air quality to a certain extent, thus meeting the user's usage requirements.

[0061] In some embodiments of the present invention, the first valve assembly 41 includes: a supply air valve 411 and an exhaust air valve 412. The supply air valve 411 is used to switch the opening and closing of the supply air outlet 22, or to switch the connection and disconnection between the supply air outlet 22 and the first air duct cavity 21; the exhaust air valve 412 is installed on the first air duct member 31 and is used to switch the connection and disconnection between the exhaust cavity 34 and the first air duct cavity 21.

[0062] For example, referring to Figures 2 - 6 shown, the first valve assembly 41 includes a supply air valve 411 and an exhaust air valve 412. Among them, the supply air valve 411 can be installed at the supply air outlet 22 so that the supply air valve 411 can be used to switch the opening and closing of the supply air outlet 22, such as opening or closing the supply air outlet 22; or, the supply air valve 411 can be installed in the first air duct cavity 21 so that the supply air valve 411 can be used to switch the connection and disconnection between the supply air outlet 22 and the first air duct cavity 21, such as connecting or disconnecting the supply air outlet 22 from the second air duct cavity 33. At the same time, the exhaust air valve 412 can be installed on the first air duct member 31 so that the exhaust air valve 412 can be used to switch the connection and disconnection between the exhaust cavity 34 and the first air duct cavity 21, such as connecting or disconnecting the exhaust cavity 34 from the first air duct cavity 21.

[0063] Specifically, as Figures 3 - 4 shown, when the air conditioner 1000 is in the fresh air mode, the air supply valve 411 can open the air supply port 22, and the exhaust valve 412 can disconnect the exhaust chamber 34 from the second air duct chamber 33, so that fresh air can be blown into the indoor space through the air supply port 22; as Figures 5 - 6 shown, when the air conditioner 1000 is in the exhaust mode, the air supply valve 411 can close the air supply port 22, and the exhaust valve 412 can connect the exhaust chamber 34 with the second air duct chamber 33, so that the indoor air can flow through the first air duct chamber 21, the exhaust chamber 34 and the communication chamber 35, and be blown out to the outdoor space through the fresh air port 321.

[0064] Through the above settings, the air outlet of the first air duct chamber 21 from the air supply port 22 or from the fresh air port 321 can be better controlled, realizing the stable switching of the fresh air module 100 between the fresh air mode and the exhaust mode, and improving the practicability of the fresh air module 100.

[0065] In some embodiments of the present invention, a second purification member 6 is provided in the first air duct chamber 21, and the air supply valve 411 is arranged in the first air duct chamber 21 and is located downstream of the second purification member 6.

[0066] It can be understood that by providing the second purification member 6, the second purification member 6 can filter and purify the air flow flowing to the air supply port 22 to improve the fresh air quality of the fresh air module 100, and by arranging the second purification member 6 upstream of the air inlet valve 421, it is possible to avoid impurities in the air flow from affecting the normal operation of the air supply valve 411, and improve the operation stability of the fresh air module 100.

[0067] In some embodiments of the present invention, the second purification member 6 can be one of a filter element, a formaldehyde removal member, an anti-allergy original member or other filter members, or can be a combination of several of a filter element, a formaldehyde removal member, an anti-allergy original member or other filter members. Thus, it is beneficial to meet the diverse needs of users.

[0068] The present invention also proposes an air conditioner 1000.

[0070] According to the air conditioner 1000 of the embodiment of the present utility model, the air inlet 321 of the fresh air can be communicated with the air outlet 22 through the air direction regulation component 4, so that the fresh air flow can be blown into the indoor space through the air outlet 22, and the air inlet 311 can be communicated with the air inlet 321 of the fresh air through the air direction regulation component 4, so that the indoor air flow can be blown out to the outdoor space through the air inlet 321 of the fresh air, thereby realizing the two-way ventilation function. Moreover, the composition of the fresh air module 100 is simple, and each part can independently define the corresponding air duct, which is easy to process and assemble, improves the practicability of the fresh air module 100, and enhances the overall performance of the air conditioner 1000.

[0071] In some embodiments of the present utility model, as Figures 8 - 9 shown, the air conditioner 1000 can be set as a floor-standing air conditioner. Among them, the air conditioner 1000 includes: a rear box body component 200, a front panel component 300, and a heat exchange and ventilation component (not shown in the figure).
