[0043] The fresh air module and air conditioner provided in this embodiment are intended to at least to some extent solve the technical problem that the fresh air module has no internal circulation function, cannot achieve indoor air purification in harsh environments, and affects the user experience.

[0044] Figure 1 Schematic diagram of the structure of the fresh air module in some embodiments; Figure 2 for Figure 1 AA cross-sectional view of the fresh air module; Figure 3 for Figure 1 Schematic diagram of fresh air intake into the fresh air module; Figure 6 for Figure 1 Schematic diagram of the internal circulation of the fresh air module. Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The fresh air module of the embodiment of the present application includes: a housing 10, a fan assembly 20, a filter 30 and an air duct 40. The housing 10 is provided with a first air inlet 101, an openable and closable air outlet 102 and an openable and closable first air outlet 103. The fan assembly 20 is arranged in the housing 10. The filter 30 is connected to the housing 10 and is arranged at the first air outlet 103. The air duct 40 is arranged in the housing 10 and is connected to the first air inlet 101. The air duct 40 is provided with an openable and closable second air inlet 401. Among them, when the fresh air module is in the fresh air intake mode, the air outlet 102 is in a closed state, the second air inlet 401 and the first air outlet 103 are in an open state, and the outdoor fresh air enters the room through the first air inlet 101, the second air inlet 401, the fan assembly 20, the first air outlet 103 and the filter 30 in sequence. When the fresh air module is in the internal circulation mode, the exhaust port 102 is in the open state, the second air inlet 401 and the first air outlet 103 are in the open state, and the indoor air enters the room through the exhaust port 102, the fan assembly 20, the first air outlet 103 and the filter element 30 in sequence.

[0045] Since the fan assembly 20 is arranged in the shell 10 and is provided with a first air inlet 101, an openable and closable exhaust port 102 and an openable and closable first air outlet 103, the filter element 30 is connected to the shell 10 and is provided at the first air outlet 103, the air duct 40 is arranged in the shell 10 and is connected to the first air inlet 101, and the air duct 40 is provided with an openable and closable second air inlet 401, the fan assembly 20, the filter element 30 and the air duct 40 are supported by the shell to ensure the stability of the installation of the fan assembly 20, the filter element 30 and the air duct 40. When the fresh air module is in the fresh air intake mode, the exhaust port 102 is in a closed state, the second air inlet 401 and the first air outlet 103 are in an open state, and the outdoor fresh air enters the room through the first air inlet 101, the second air inlet 401, the fan assembly 20, the first air outlet 103 and the filter element 30 in turn, which can make Outdoor fresh air enters the room, improving the indoor air quality and user comfort. Moreover, the filter element 30 can filter the outdoor fresh air to remove particulate matter in the outdoor fresh air, further improving the indoor air quality and user comfort. When the fresh air module is in the internal circulation mode, the exhaust port 102 is in an open state, the second air inlet 401 and the first air outlet 103 are in an open state, and the indoor air enters the room through the exhaust port 102, the fan assembly 20, the first air outlet 103 and the filter element 30 in turn. The indoor air can be filtered by the filter element 30 to remove pollutants in the indoor air, thereby achieving indoor air purification, improving indoor air quality and user comfort. Moreover, when the fresh air module is in the fresh air intake state and the internal circulation state, the same filter element 30 is used, and there is no need to add extra filter elements 30, thereby reducing costs.

[0046] In some embodiments, the filter element 30 can be installed inside the first air outlet 103 or outside the first air outlet 103. Along the air outlet direction, the projection of the filter element 30 on the shell 10 at least partially overlaps with the first air outlet 103 on the shell 10, so that the wind entering the room from the first air outlet 103 passes through the filter element 30, and the air is filtered by the filter element 30, thereby improving the indoor air quality and improving user comfort.

[0047] Figure 10 for Figure 1 Schematic diagram of sewage exhaust from the fresh air module; Figure 11 for Figure 10 Top view of the fresh air module; Figure 12 for Figure 11 EE cross-sectional view of the fresh air module. Figure 3 、 Figure 6 、 Figure 10 、 Figure 11 and Figure 12In some embodiments, to exhaust indoor polluted air, the air duct 40 is provided with an openable and closable second air outlet 402. When the fresh air module is in fresh air intake mode or internal circulation mode, the second air outlet 402 is closed. When the fresh air module is in polluted air exhaust mode, the second air outlet 402 and the exhaust port 102 are open, while the first air outlet 103 and the second air inlet 401 are closed. Indoor air then passes through the exhaust port 102, the fan assembly 20, the second air outlet 402, and the first air inlet 101 in sequence to enter the outdoors.

[0048] In some embodiments, to ensure the normal operation of the air module in the fresh air intake mode and the internal circulation mode, the second air outlet 402 is closed when the fresh air module is in the fresh air intake mode and the internal circulation mode to prevent the second air outlet 402 from interfering with the flow of fresh air and indoor air. When the fresh air module is in the sewage exhaust mode, the second air outlet 402 and the exhaust port 102 are in an open state, and the first air outlet 103 and the second air inlet 401 are in a closed state. The indoor air passes through the exhaust port 102, the fan assembly 20, the second air outlet 402 and the first air inlet 101 in sequence to enter the outdoors, which can discharge the indoor polluted air outdoors, improve the indoor air quality, effectively reduce the concentration of harmful gases in the room, and improve user comfort.

[0049] In some embodiments, when the fresh air module is in the exhaust air mode, the indoor air will not pass through the filter element 30, and the filter element 80 does not need to process this part of the exhaust air, which can reduce the amount of dust, particles and other pollutants accumulated on the filter element 30, thereby significantly extending the replacement cycle and service life of the filter element 30. Moreover, since the filter element 30 does not participate in the work in the exhaust air mode, the exhaust resistance can be reduced, ensuring smooth exhaust air.

[0050] Combine Figure 10 、 Figure 11 and Figure 12 In some embodiments, in order to ensure smooth intake of fresh air and exhaust of sewage air, the second air outlet 402 is located between the first air outlet 103 and the second air inlet 401, and the second air inlet 401 is located between the first air inlet 101 and the second air outlet 402. That is to say, when taking in fresh air, it is ensured that outdoor air can enter the second air inlet 401 through the air duct 40 without passing through the second air outlet 402. When exhausting sewage air, the indoor air can enter the air duct 40 through the second air outlet 402 and then be discharged from the first air inlet 101, without passing through the second air inlet 401 to reach the fan assembly 20, thereby ensuring smooth ventilation.

[0051] In some embodiments, to achieve fresh air intake, exhaust of waste air, and internal circulation in the fresh air module, the fan assembly 20 has an air inlet and an air outlet. When the second air inlet 401 is open, the second air inlet 401 communicates with the air inlet. When the second air outlet 402 is open, the second air outlet 402 communicates with the air outlet. When the first air outlet 103 is open, the first air outlet 103 communicates with the air outlet. When the exhaust port 102 is open, the exhaust port 102 communicates with the air inlet.

[0052] In some embodiments, when fresh air is to be introduced, the fan assembly 20 is started, the exhaust port 102 and the second air outlet 402 are closed, and the first air outlet 103 and the second air inlet 401 are opened. The outdoor fresh air enters the fan assembly 20 in sequence through the first air inlet 101, the air duct 40, the second air inlet 401, and the air inlet end, and then enters the room through the air outlet end and the first air outlet 103, thereby introducing fresh air into the room and improving the indoor air quality. When dirty air is to be discharged, the first air outlet 103 and the second air inlet 401 are closed, and the exhaust port 102 and the second air outlet 402 are opened. The indoor dirty air is discharged in sequence through the exhaust port 102, the air inlet end, the fan assembly 20, the air outlet end, the second air outlet 402, the air duct 40, and the first air inlet 101, thereby improving the indoor air quality and effectively reducing the concentration of harmful gases in the room. When the fresh air module is in the internal circulation mode, the exhaust port 102 and the first air outlet 103 are opened, and the second air inlet 401 and the second air outlet 402 are closed. The indoor air enters the room through the exhaust port 102, the air inlet end, the fan assembly 20, the air outlet end, the first air outlet 103 and the filter element 30 in sequence. The indoor air can be filtered by the filter element 30 to remove pollutants in the indoor air, thereby achieving indoor air purification, improving indoor air quality, and improving user comfort.

[0053] Figure 4 for Figure 3 BB cross-sectional view of the fresh air module; Figure 5 for Figure 3 Schematic diagram of the layout of the blocking components of the fresh air module; Figure 7 for Figure 6 Top view of the fresh air module; Figure 8 for Figure 7 CC cross-sectional view of the fresh air module. Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 、 Figure 11 and Figure 12In some embodiments, in order to control the opening and closing of the second air inlet 401 and the second air outlet 402, the air conditioner further includes: a blocking component 50. The blocking component 50 is arranged in the air duct 40 and can be switched between a first position, a second position, and a third position. When the blocking component 50 is in the first position, the blocking component 50 opens the second air inlet 401 and closes the second air outlet 402. When the blocking component 50 is in the second position, the blocking component 50 closes the second air inlet 401 and opens the second air outlet 402. When the blocking component 50 is in the third position, the blocking component 50 closes the second air inlet 401 and the second air outlet 402.

[0054] In some embodiments, when fresh air is to be introduced, the fan assembly 20 is activated, the blocking assembly 50 is in the first position, the second air inlet 401 is opened, the second air outlet 402 is closed, the exhaust port 102 is closed, and the first air outlet 103 is opened. The fresh air from the outside enters the room through the first air inlet 101, the air duct 40, the second air inlet 401, the fan assembly 20, and the first air outlet 103 in sequence, thereby introducing fresh air into the room and improving the indoor air quality. When dirty air is to be discharged, when the blocking assembly 50 is in the second position, the blocking assembly 50 closes the second air inlet 401 and opens the second air outlet 402, the first air outlet 103 is closed, and the exhaust port 102 is opened. The dirty air in the room is discharged through the exhaust port 102, the fan assembly 20, the second air outlet 402, the air duct 40, and the first air inlet 101 in sequence, thereby improving the indoor air quality and effectively reducing the concentration of harmful gases in the room. When the fresh air module is in the internal circulation mode, the blocking component 50 is located at the third position, and the blocking component 50 closes the second air inlet 401 and the second air outlet 402 .

[0055] Combine Figure 4 、 Figure 5 、 Figure 8 and Figure 12 In some embodiments, in order to control the opening and closing of the second air inlet 401 and the second air outlet 402, the blocking component 50 includes: a first blocking member 501 and a second blocking member 502. The first blocking member 501 is rotatably disposed in the air duct 40. The second blocking member 502 is rotatably disposed in the air duct 40. When the blocking component 50 is in the first position, the first blocking member 501 opens the second air inlet 401, and the second blocking member 502 closes the second air outlet 402. When the blocking component 50 is in the second position, the first blocking member 501 closes the second air inlet 401, and the second blocking member 502 opens the second air outlet 402. When the blocking component 50 is in the third position, the first blocking member 501 closes the second air inlet 401, and the second blocking member 502 closes the second air outlet 402.

[0056] In some embodiments, when fresh air is to be introduced, the fan assembly 20 is started and the blocking assembly 50 is in the first position. At this time, the first blocking member 501 opens the second air inlet 401, the second blocking member 502 closes the second air outlet 402, the exhaust port 102 is in a closed state, and the first air outlet 103 is in an open state. The fresh air outside enters the room through the first air inlet 101, the air duct 40, the second air inlet 401, the fan assembly 20 and the first air outlet 103 in sequence, thereby introducing fresh air into the room and improving the indoor air quality. When exhausting polluted air, the blocking assembly 50 is in the second position. At this time, the first blocking member 501 closes the second air inlet 401, and the second blocking member 502 opens the second air outlet 402. The first air outlet 103 is closed, and the exhaust port 102 is open. The indoor polluted air is discharged sequentially through the exhaust port 102, the fan assembly 20, the second air outlet 402, the air duct 40, and the first air inlet 101, thereby improving indoor air quality and effectively reducing the concentration of harmful gases indoors. When the fresh air module is in internal circulation mode, the blocking assembly 50 is in the third position. The first blocking member 501 closes the second air inlet 401, and the second blocking member 502 closes the second air outlet 402.

[0057] Combine Figure 4 In some embodiments, to enable the first and second blocking members 501, 502 to operate within the air duct 40, each of the first and second blocking members 501, 502 includes a sealing plate 5011 and a driver 5012. The sealing plate 5011 is disposed within the air duct 40. The driver 5012 is connected to the sealing plate 5011 to drive the sealing plate 5011 to rotate within the air duct 40. The driver 5011 may be a motor.

[0058] Combine Figure 3 In some embodiments, in order to ensure the structural strength of the filter element 30, the filter element 30 is rectangular. Compared with the arc shape, the rectangular structure can provide a larger area under a given perimeter. The increase in area means that the material is more evenly distributed, thereby enhancing the support force and stability of the filter element 30. Moreover, the length-to-width ratio of the rectangular structure is relatively balanced, which can help disperse external forces, reduce stress concentration points, and ensure the service life of the filter element 30.

[0059] In some embodiments, in order to detect the indoor carbon dioxide content, the fresh air module further includes: a carbon dioxide detector. The carbon dioxide detector is provided in the housing and is used to detect the indoor carbon dioxide content.

[0060] In some embodiments, the fresh air module further includes a controller electrically connected to a carbon dioxide detector, which detects the indoor carbon dioxide concentration and sends the detected indoor carbon dioxide concentration value to the controller. The controller compares the indoor carbon dioxide concentration value detected by the carbon dioxide detector with a preset carbon dioxide concentration value. If the carbon dioxide concentration value is greater than the preset carbon dioxide concentration value, the exhaust port 102 and the second air outlet 402 are closed, and the second air inlet 401 and the first air outlet 103 are opened. At the same time, the fan assembly 20 is started, and the fan assembly 20 draws fresh air. The outdoor fresh air enters the room through the first air inlet 101, the second air inlet 401, the fan assembly 20, the first air outlet 103 and the filter element 30 in sequence, thereby improving the indoor air quality and user comfort.

[0061] In some embodiments, in order to detect the total volatile organic compound content in the room, the fresh air module further includes: a total volatile organic compound detector. The total volatile organic compound detector is disposed in the housing and is used to detect the total volatile organic compound content in the room.

[0062] In some embodiments, a total volatile organic compound (TVOC) detector is electrically connected to a controller. The TVOC detector detects the total volatile organic compound (TVOC) concentration in the room and sends the detected TVOC concentration value to the controller. The controller compares the TVOC concentration value detected by the TVOC detector with a preset TVOC concentration value. If the TVOC concentration value is greater than the preset TVOC concentration value, the controller opens the second air outlet 402 and the exhaust port 102, closes the first air outlet 103 and the second air inlet 401, and starts the fan assembly 20. The fan assembly 20 extracts the polluted air, and the indoor air is discharged outdoors through the third air outlet 103, the fan assembly 20, the air duct 30, the fourth air outlet 301, and the first air outlet 101 in sequence. This can discharge the polluted air outdoors, improve the indoor air quality, effectively reduce the concentration of harmful gases indoors, and improve user comfort.

[0063] When fresh air is introduced, the first air outlet 103 will discharge a large amount of fresh air that has not been affected by the indoor environment. If the carbon dioxide detector and the total volatile organic compound detector are located near the first air outlet 103, they may be directly affected by the fresh air, resulting in a low detected carbon dioxide concentration and total volatile organic compound concentration, thereby reducing the detection accuracy. In some embodiments, in order to ensure the detection accuracy of the carbon dioxide detector and the total volatile organic compound detector, the carbon dioxide detector and the total volatile organic compound detector are closer to the exhaust port 102 than the first air outlet 103, so that the carbon dioxide detector and the total volatile organic compound detector are located at a position closer to the actual state of the indoor environment (i.e., near the exhaust port 102). When fresh air is introduced, the effect of the fresh air discharged from the first air outlet 103 on the detection accuracy of the carbon dioxide detector and the total volatile organic compound detector can be reduced, and it can be ensured that the carbon dioxide detector and the total volatile organic compound detector detect gases that have been fully mixed with the indoor ambient air, reducing the interference of the fresh air on the detection results, and being able to more accurately reflect the carbon dioxide and total volatile organic compound concentrations in the indoor air.

[0064] Combine Figure 5 、 Figure 6 、 Figure 9 and Figure 10 In some embodiments, in order to control the opening and closing of the first air outlet 103 and the exhaust outlet 102, the air conditioner further includes: a third blocking member 60 and a fourth blocking member 70. The third blocking member 60 is provided in the housing 10 and can be switched between a fourth position and a fifth position to control the opening and closing of the first air outlet 103. The fourth blocking member 70 is provided in the housing 10 and can be switched between a sixth position and a seventh position to control the opening and closing of the exhaust outlet 102. When the third blocking member 60 is in the fourth position, the first air outlet 103 is in an open state, and when the third blocking member 60 is in the fifth position, the first air outlet 103 is in a closed state.
