[0058] Reference below Figures 1-20 A fan assembly according to an embodiment of the present invention is described.

[0059] like Figures 1-20 As shown, the fan assembly according to an embodiment of the present invention includes: a housing 10, a rotating assembly 20, a wind wheel 40 and a driving assembly, the housing 10 has a accommodating cavity, a first air inlet duct 116, a first air outlet duct 127, a second air inlet duct 117 and a second air outlet duct 128.

[0060] The first air inlet duct 116 and the first air outlet duct 127 are respectively connected to the outdoor side so that the accommodating chamber is connected to the outdoor side, and the second air inlet duct 117 and the second air outlet duct 128 are respectively connected to the indoor side so that the accommodating chamber is connected to the indoor side; and the second air inlet duct 117 and the second air outlet duct 128 are arranged at intervals, so that the second air inlet duct 117 and the second air outlet duct 128 are independent of each other, which can reduce pressure loss, improve the air inlet and outlet efficiency of the fan assembly, and thereby increase the air inlet and outlet air volumes.

[0061] The rotating component 20 is arranged in the accommodating cavity, and the rotating component 20 can rotate in the accommodating cavity, and the rotating component 20 can separate the accommodating cavity into an air inlet cavity 103 and an air outlet cavity 104. The first air inlet duct 116 and the second air inlet duct 117 are respectively connected to the air inlet cavity 103, so that the air inlet cavity 103 is respectively connected to the indoor and outdoor areas, and the first air outlet duct 127 and the second air outlet duct 128 are respectively connected to the air outlet cavity 104, so that the air outlet cavity 104 is respectively connected to the indoor and outdoor areas.

[0062] The rotating assembly 20 has an air inlet baffle 22 and an air outlet baffle 23. The air inlet baffle 22 can control the connection and disconnection between the air inlet cavity 103 and the first air inlet duct 116, and the air inlet baffle 22 can control the connection and disconnection between the air inlet cavity 103 and the second air inlet duct 117. The air outlet baffle 23 can control the connection and disconnection between the air outlet cavity 104 and the first air outlet duct 127, and the air outlet baffle 23 can control the connection and disconnection between the air outlet cavity 104 and the second air outlet duct 128.

[0063] The wind wheel 40 is arranged in the air inlet chamber 103 or the air outlet chamber 104, and the driving component is arranged on the outer shell 10. The driving component can be connected to the wind wheel 40 to drive the wind wheel 40 to rotate, and the driving component can be connected to the rotating component 20 to drive the rotating component 20 to rotate, so that the air inlet baffle 22 can disconnect the air inlet chamber 103 and the second air inlet duct 117, and the air outlet baffle 23 can disconnect the air outlet chamber 104 and the first air outlet duct 127, so that the outdoor air can first enter the air inlet chamber 103 through the first air inlet duct 116, then enter the air outlet chamber 104, and then flow out through the second air outlet duct 128, so that a first passage can be formed in the outer shell 10.

[0064] The driving assembly can continue to drive the rotating assembly 20 to rotate, so that the air inlet baffle 22 can disconnect the air inlet cavity 103 and the first air inlet duct 116, and the air outlet baffle 23 can disconnect the air outlet cavity 104 and the second air outlet duct 128, so that the indoor air can first enter the air inlet cavity 103 through the second air inlet duct 117, then enter the air outlet cavity 104, and then flow out through the first air outlet duct 127, so that a second passage can be formed in the outer shell 10; that is, by driving the driving assembly to rotate, the air can flow in different passages, which is conducive to switching the working mode of the fan assembly and is convenient for operation.

[0065] According to the fan assembly of an embodiment of the present invention, an air inlet baffle 22 and an air outlet baffle 23 are provided on the rotating assembly 20, so that the rotating assembly 20 can control the opening and closing of different air ducts and different chambers during rotation, so that air can flow into the housing 10 through different air ducts and flow out of the housing 10 through different air ducts to form passages in multiple directions in the housing 10, which can enrich the working mode of the fan assembly and improve the user experience. The working mode of the fan assembly can be switched by driving the rotating assembly 20 to rotate, which is convenient for operation.

[0066] In addition, by driving the rotating assembly 20 to rotate to switch the passage, compared with setting a wind valve in each passage and each wind valve requiring a separate motor drive, the motion mechanism in the fan assembly can be reduced, the structure of the fan assembly can be simplified, and the space utilization of the fan assembly can be improved, which is conducive to reducing the volume of the fan assembly, realizing the miniaturization of the fan assembly, and can improve the reliability of the fan assembly, and is conducive to reducing the cost of the fan assembly.

[0067] like Figure 10 and Figure 13 As shown, according to some embodiments of the present invention, the first air outlet duct 127 overlaps with at least a portion of the first air inlet duct 116, and the first air outlet duct 127 and the first air inlet duct 116 are connected to each other, that is, the first air outlet duct 127 and the first air inlet duct 116 can cooperate with each other to form a first opening 101 on the outdoor side of the fan assembly, so that the first air outlet duct 127 and the first air inlet duct 116 share the first opening 101, thereby facilitating the external piping of the first opening 101 to connect with the outdoor unit. Compared with the first air inlet duct 116 and the first air outlet duct 127 having separate external piping, the piping can be simplified, maintenance is facilitated, and costs are reduced.

[0068] It can be understood that the housing 10 can have a first opening 101, and the first opening 101 can be an outdoor opening. The first opening 101 can be located at the open end of the first air inlet duct 116, so that the first air inlet duct 116 can be connected to the outdoor side through the first opening 101. At the same time, the first opening 101 can be located at the open end of the first air outlet duct 127, so that the first air outlet duct 127 can be connected to the outdoor side through the first opening 101. In other words, the first air inlet duct 116 and the first air outlet duct 127 can share an opening (outdoor opening) to connect the accommodating cavity with the outdoors.

[0069] like Figure 1 、 Figure 16 and Figure 17 As shown, according to some embodiments of the present invention, the housing 10 has a second opening 102 and a third opening 106, and the second opening 102 and the third opening 106 can both be indoor openings. The second opening 102 can be located at the open end of the second air inlet duct 117, so that the second air inlet duct 117 can be connected to the indoor side through the second opening 102, and the third opening 106 can be located at the open end of the second air outlet duct 128, so that the second air outlet duct 128 can be connected to the indoor side through the third opening 106.

[0070] In other words, the second air inlet duct 117 and the second air outlet duct 128 can respectively adopt different openings (indoor openings) to connect the accommodating cavity with the indoor room, so that the second air inlet duct 117 and the second air outlet duct 128 can be independent of each other, and since the second air outlet duct 128 corresponds to the first passage and the second air inlet duct 117 corresponds to the second passage, it is beneficial to increase the ventilation volume of the first passage and the second passage, and to improve the air supply efficiency of the fan assembly.

[0071] like Figure 17 As shown, the second opening 102 and the third opening 106 can be arranged along the rotation circumference of the rotating component 20, and the second opening 102 and the third opening 106 can be separated, which is beneficial to reducing the length of the second air inlet duct 117 or the second air outlet duct 128. For example, the distance between the second opening 102 and the rotation center of the rotating component 20 can be reduced to reduce the length of the second air inlet duct 117, which is beneficial to reducing the flow resistance of the indoor air in the second air inlet duct 117, thereby helping to increase the ventilation volume of the second passage and improve the air supply efficiency of the fan assembly.

[0072] like Figure 1 and Figure 17 As shown, the extension direction of the center line of the second opening 102 and the extension direction of the center line of the third opening 106 can be different, so that the opening direction of the second opening 102 and the opening direction of the third opening 106 can be different. For example, Figure 1As shown, the third opening 106 can be opened to the front side of the fan assembly (eg Figure 1 The front side shown in the figure is open, which can reduce the probability of indoor obstructions (such as walls) blocking the third opening 106, which is beneficial to increasing the air supply volume of the fan assembly, increasing the ventilation volume of the first passage, and improving the air supply efficiency of the fan assembly. The second opening 102 can be opened to the upper side of the fan assembly (such as the front side shown in the figure). Figure 1 The upper side shown in the figure is open, which helps to reduce the diffusion of wind noise in the room, reduce the working noise of the fan assembly, and improve the user experience.

[0073] Or, as Figure 8 As shown, the second opening 102 can be to the left side of the fan assembly (eg Figure 8 The left side as shown is open, and based on reducing the working noise of the fan assembly, the probability of indoor obstructions (such as the wall top) blocking the second opening 102 can be reduced, which is beneficial to increasing the air supply of the fan assembly, increasing the ventilation volume of the second passage, and improving the air supply efficiency of the fan assembly.

[0074] In addition, the extension direction of the center line of the second opening 102 and the extension direction of the center line of the third opening 106 can be the same, that is, the opening direction of the second opening 102 and the opening direction of the third opening 106 can be the same, for example, Figure 7 As shown, the second opening 102 can be opened to the front side of the fan assembly (such as Figure 7 The front side as shown in the figure is open, so that the second opening 102 and the third opening 106 are open to the same side of the fan assembly, which can reduce the probability of indoor obstructions (such as walls) blocking the second opening 102 and the third opening 106, and can improve the air supply efficiency of the fan assembly. At the same time, the length of the second air inlet duct 117 can be reduced, and the flow resistance of the indoor air in the second air inlet duct 117 can be reduced, so as to further improve the air supply efficiency of the fan assembly.

[0075] like Figure 1 、 Figure 7 and Figure 8 As shown, in some examples, the second air outlet duct 128 and the third opening 102 are both located on the upper side of the fan assembly (eg, Figure 1 The upper side shown in the figure) can increase the height of the second air outlet duct 128 and the third opening 102, so that the third opening of the fan assembly is away from the user, which is beneficial to reduce the diffusion degree of the air supply noise in the room, and further helps to reduce the working noise of the fan assembly, which can improve the user experience.

[0076] In some examples, the minimum distance between the second air inlet 112 and the second opening 102 is smaller than the minimum distance between the second air outlet 122 and the third opening 106, which can reduce the length of the second air inlet duct 117, thereby helping to reduce the flow resistance of indoor air in the second air inlet duct 117, thereby helping to increase the ventilation volume of the second passage and improve the air supply efficiency of the fan assembly.

[0077] like Figure 10-13 As shown, according to some embodiments of the present invention, the housing 10 has a first air inlet 111 and a second air inlet 112, the first air inlet 111 is used to connect the first air inlet duct 116 and the air inlet cavity 103, and the second air inlet 112 is used to connect the second air inlet duct 117 and the air inlet cavity 103; the housing 10 also has a first air outlet 121 and a second air outlet 122, the first air outlet 121 is used to connect the first air outlet duct 127 and the air outlet cavity 104, and the second air outlet 122 is used to connect the second air outlet duct 128 and the air outlet cavity 104.

[0078] like Figure 1-Figure 3 As shown, according to some embodiments of the present invention, the housing 10 includes: a first shell 11 and a second shell 12, the first shell 11 defines an air inlet cavity 103, the second shell 12 defines an air outlet cavity 104, and the first shell 11 and the second shell 12 are arranged along the rotation axis of the rotating assembly 20 (as shown in FIG. Figure 9 The first shell 11 and the second shell 12 are fixedly connected by fasteners.

[0079] like Figures 9-15 As shown, the first air inlet 111 and the first air outlet 121 can be along the rotation axis of the wind wheel 40 (as shown in FIG. Figure 9 The partition plate 21 of the rotating assembly 20 can separate the air inlet chamber 103 from the air outlet chamber 104, and the partition plate 21 can cooperate with the first shell 11 to define a first air inlet 111 on one side of the air inlet chamber 103 and a second air inlet 112 on the other side of the air inlet chamber 103. The second air inlet 112 and the second air outlet 122 can be arranged along the rotation axis of the wind wheel 40 (as shown in the left and right directions). Figure 9 The partition plate 21 can cooperate with the second shell 12 to define a second air inlet 112 on one side of the air outlet cavity 104 and a second air outlet 122 on the other side of the air outlet cavity 104.

[0080] Among them, the first air inlet duct 116 and the second air inlet duct 117 are located in the first shell 11, so that the first air inlet duct 116 can be connected with the air inlet cavity 103 through the first air inlet port 111, and the second air inlet duct 117 can be connected with the air inlet cavity 103 through the second air inlet port 112; the first air outlet duct 127 is located in the second shell 12, so that the first air outlet duct 127 can be connected with the air outlet cavity 104 through the first air outlet port 121.

[0081] A portion of the second air outlet duct 128 can be located in the first shell 11, and the other portion of the second air outlet duct 128 can be located in the second shell 12, that is, the second air outlet duct 128 can be formed by splicing the first shell 11 and the second shell 12, which is beneficial to increase the cross-sectional area of ​​the second air outlet duct 128, and thus is beneficial to increase the air supply volume of the fan assembly; or, the entire second air outlet duct 128 can be located in the second shell 12, which is beneficial to reduce the cost of the outer shell 10 and facilitates processing.

[0082] like Figure 13 As shown, in some examples, the second shell 12 has an air guide plate 126, which is arranged in the second air outlet duct 128, and the air guide plate 126 can extend along the extension direction of the second air outlet duct 128, so as to guide the airflow in the second air outlet duct 128, improve the stability of the air flow in the second air outlet duct 128, and reduce the probability of turbulence in the second air outlet duct 128, which is beneficial to increase the ventilation volume of the first passage and improve the air supply efficiency of the fan assembly.

[0083] It is understandable that the number of the air guide plates 126 can be multiple, for example, the number of the air guide plates 126 is two, and the two air guide plates 126 are at the height direction of the second air outlet duct 128 (such as Figure 13 The spacing arrangement in the upper and lower directions (as shown) can improve the guiding effect of the airflow and further improve the stability of the air flow.

[0084] like Figure 10-15 As shown, according to some embodiments of the present invention, the rotating assembly 20 further includes a partition plate 21, which is located between the air inlet chamber 103 and the air outlet chamber 104, and the partition plate 21 is formed in a ring shape. The partition plate 21 is provided with a communication port 211, and the communication port 211 can connect the air inlet chamber 103 and the air outlet chamber 104. The air inlet baffle 22 can be provided on the side of the partition plate 21 facing the air inlet chamber 103 (as shown in FIG. Figure 14 The left side shown in the figure) is beneficial for the air inlet baffle 22 to block the first air inlet 111 during the rotation of the rotating component 20, so as to disconnect the air inlet cavity 103 and the first air inlet duct 116, and is beneficial for the air inlet baffle 22 to block the second air inlet 112 during the rotation of the rotating component 20, so as to disconnect the air outlet cavity 104 and the second air inlet duct 117.

[0085] The air outlet baffle 23 can be arranged on the side of the partition plate 21 facing the air outlet cavity 104 (eg Figure 14 The right side shown in the figure) is beneficial for the air outlet baffle 23 to cover the first air outlet 121 during the rotation of the rotating component 20, so as to disconnect the air outlet cavity 104 and the first air outlet duct 127, and is beneficial for the air inlet baffle 22 to cover the second air outlet 122 during the rotation of the rotating component 20, so as to disconnect the air outlet cavity 104 and the second air outlet duct 128.

[0086] like Figure 10-15 As shown, in some examples, the air inlet baffle 22 can block the second air inlet 112, and the air outlet baffle 23 can block the first air outlet 121, so that outdoor air can enter the first air inlet duct 116 through the first opening 101, then enter the air inlet cavity 103 through the first air inlet 111, and then enter the air outlet cavity 104 through the connecting port 211, and then enter the second air outlet duct 128 through the second air outlet 122, and finally flow into the room through the third opening 106, which can realize air supply to the room, and the outdoor air can be filtered to realize fresh air supply to the room.

[0087] The air inlet baffle 22 can block the first air inlet 111, and the air outlet baffle 23 can block the second air outlet 122, so that the indoor air can enter the second air inlet duct 117 through the second opening 102, then enter the air inlet cavity 103 through the second air inlet 112, and then enter the air outlet cavity 104 through the connecting port 211, and then enter the first air outlet duct 127 through the first air outlet 121, and finally flow to the outside through the first opening 101 to be exhausted to the outside, for example, the dirty air in the room can be discharged.

[0088] In other examples, the first opening 101 can be an indoor opening, the second opening 102 and the third opening 106 can both be outdoor openings, the air inlet baffle 22 can block the second air inlet 112, and the air outlet baffle 23 can block the first air outlet 121, so that the indoor air can enter the first air inlet duct 116 through the first opening 101, then enter the air inlet cavity 103 through the first air inlet 111, and then enter the air outlet cavity 104 through the connecting port 211, and then enter the second air outlet duct 128 through the second air outlet 122, and finally flow to the outside through the third opening 106 to exhaust air to the outside, for example, the dirty air in the room can be discharged.

[0089] The air inlet baffle 22 can block the first air inlet 111, and the air outlet baffle 23 can block the second air outlet 122, so that outdoor air can enter the second air inlet duct 117 through the second opening 102, and then enter the air inlet cavity 103 through the second air inlet 112, and then enter the air outlet cavity 104 through the connecting port 211, and then enter the first air outlet duct 127 through the first air outlet 121, and finally flow into the room through the first opening 101, which can realize air supply to the room, and the outdoor air can be filtered to realize fresh air supply to the room.

[0090] like Figure 9 and Figure 16 As shown, according to some embodiments of the present invention, the wind wheel 40 can be arranged in the air outlet chamber 104, the air outlet baffle 23 is located on the periphery of the wind wheel 40, and the driving assembly is connected to the wind wheel 40 to drive the wind wheel 40 to rotate, wherein the wind wheel 40 can be a centrifugal wind wheel 40, and the rotation of the wind wheel 40 can pump the air in the air inlet chamber 103 into the air outlet chamber 104.

[0091] like Figure 5 、 Figure 14 and Figure 15 As shown, a volute tongue section 233 is formed at one end of the air outlet baffle 23. Along the direction away from the volute tongue section 233 and in the extending direction of the air outlet baffle 23, the distance between at least a portion of the side surface of the air outlet baffle 23 close to the wind wheel 40 and the rotation center of the wind wheel 40 gradually increases or decreases. For example, Figure 5 As shown, in the rotation direction of the wind wheel 40, the distance between at least a portion of the inner surface of the air outlet baffle 23 and the rotation center of the wind wheel 40 gradually increases, which can guide the air flow and improve the stability of the air flow.

[0092] Among them, a part of the side surface of the air outlet baffle 23 close to the wind wheel 40 can gradually increase or decrease the distance from the rotation center of the wind wheel 40, which is convenient for processing and helps to reduce costs; a part of the side surface of the air outlet baffle 23 close to the wind wheel 40 can gradually increase or decrease the distance from the rotation center of the wind wheel 40, which can extend the path of the passage that guides the airflow, so as to further improve the stability of the air flow and improve the air outlet efficiency of the fan assembly.

[0093] like Figure 14 and Figure 15As shown, in some examples, the air outlet baffle 23 includes a first shielding segment 231 and a second shielding segment 232, the first shielding segment 231 extends along the outer periphery of the partition plate 21, the second shielding segment 232 is located on the side of the first shielding segment 231 close to the wind wheel 40, one end of the second shielding segment 232 is connected to the first shielding segment 231, the other end of the second shielding segment 232 is spaced apart from the first shielding segment 231, and the other end of the second shielding segment 232 is transitionally connected to the first shielding segment 231 through the volute tongue segment 233.

[0094] It can be understood that the surface of the volute tongue segment 233 can be arc-shaped, so that the other end of the second blocking segment 232 is connected to the first blocking segment 231 in an arc transition, which can improve the guiding effect of the volute tongue segment 233 on the air flow, prevent the air from circulating in the rotating component 20, and reduce the probability of turbulence in the rotating component 20, which is beneficial to increase the air output of the fan component and improve the air output efficiency of the fan component. The air output here includes both the fan component sending fresh air to the room and the fan component exhausting air to the outside.

[0095] It should be noted that the distance between the side surface of the second shielding section 232 close to the wind wheel 40 and the rotation center of the wind wheel 40 gradually increases or decreases. For example, in the rotation direction of the wind wheel 40, the distance between the inner wall surface of the second shielding section 232 and the wind wheel 40 gradually increases, which can guide the air flow and improve the stability of the air flow. At the same time, on the flow path of the air in the air outlet cavity 104, the size of the passage gradually increases, which is beneficial to reduce the probability of turbulence in the fan assembly, and thus is beneficial to reducing the flow resistance of the air, which is beneficial to increasing the air output of the fan assembly and improving the air outlet efficiency of the fan assembly.

[0096] Specifically, if Figure 5 As shown, the second driving motor 32 can drive the wind wheel 40 to rotate counterclockwise, and in the counterclockwise direction, the distance between the inner wall surface of the second blocking section 232 and the wind wheel 40 gradually increases.

[0097] like Figure 5 and Figure 15 As shown, in some examples, a reinforcing rib 2321 can be provided between the second shielding section 232 and the first shielding section 231, which can improve the structural strength of the air outlet baffle 23, prevent the air outlet baffle 23 from being damaged when the fan assembly is working, facilitate maintenance, and enable the air outlet baffle 23 to withstand airflow with a higher flow rate, thereby increasing the rotation speed of the wind wheel 40, thereby increasing the air inlet and outlet volume of the fan assembly and improving the working effect of the fan assembly.

[0098] like Figure 9 and Figure 14As shown, in some examples, the drive assembly includes: a first drive motor 31 and a gear 30, the output shaft of the first drive motor 31 is connected to the gear 30, and a meshing tooth 2311 is provided on the side of the first blocking section 231 facing away from the second blocking section 232, and the gear 30 is engaged with the meshing tooth 2311. The first drive motor 31 can drive the gear 30 to rotate to drive the entire rotating assembly 20 to rotate through the air outlet baffle 23; or, the air inlet baffle 22 can be provided with a meshing tooth 2311, and the gear 30 is engaged with the meshing tooth 2311. The first drive motor 31 can drive the gear 30 to rotate to drive the entire rotating assembly 20 to rotate through the air inlet baffle 22.

[0099] It can be understood that by arranging meshing teeth 2311 on the side of the first blocking segment 231 facing away from the second blocking segment 232, so as to facilitate arranging the first drive motor 31 and the gear 30 outside the rotating assembly 20, the probability of the first drive motor 31 and the gear 30 interfering with the airflow can be reduced, which is beneficial to reducing the flow resistance of the air inside the fan assembly and improving the working efficiency of the fan assembly.

[0100] It should be noted that the meshing teeth 2311 can be arranged on the first shielding segment 231 along the rotation circumference of the rotating component 20, and the meshing teeth 2311 can be located on one side of the first shielding segment 231 (such as Figure 14 The right side) edge as shown is convenient for processing, and the meshing tooth 2311 can also be located on the side surface of the first blocking section 231 away from the second blocking section 232, which can improve the stability of the meshing of the meshing tooth 2311 and the gear 30, and prevent the air outlet baffle 23 from moving left and right when the rotating component 20 rotates, thereby improving the stability of the rotation of the rotating component 20.

[0101] like Figure 9 and Figure 12 As shown, in some examples, a gear mounting portion 123 is provided on the second shell 12, and the gear mounting portion 123 is located outside the air outlet chamber 104. The outer shell 10 also includes a gear cover 33, and the gear cover 33 may have a groove, and the open mouth of the groove faces the gear mounting portion 123. The first drive motor 31 can be placed in the groove, and the first drive motor 31 can be engaged with the groove, and the first drive motor 31 can be fixedly connected to the gear mounting portion 123. The gear 30 is located between the gear mounting portion 123 and the first drive motor 31, and the output shaft of the first drive motor 31 is connected to the gear 30.

[0102] The gear cover 33 can be connected to the second shell 12 to install the first drive motor 31 and the gear 30 into the gear mounting portion 123, so as to hide the first drive motor 31 and the gear 30, which is beneficial to improving the aesthetics of the fan assembly; the side wall of the air outlet cavity 104 is provided with a avoidance opening 1231, and the gear 30 engages with the meshing teeth 2311 on the air outlet baffle 23 through the avoidance opening 1231, and then the first drive motor 31 can drive the gear 30 to rotate, so as to drive the entire rotating assembly 20 to rotate through the air outlet baffle 23.

[0103] like Figure 14 and Figure 15 As shown, in some examples, the partition plate 21 is formed in a ring shape, the air inlet baffle 22 and the air outlet baffle 23 extend along the circumference of the partition plate 21, and the projections of the air inlet baffle 22 and the air outlet baffle 23 on the partition plate 21 are staggered. Since the first opening 101 (outdoor opening) and the second opening 102 (indoor opening) are respectively located on opposite sides of the housing 10 (such as Figure 1 As shown in the upper and lower sides, the first opening 101 (outdoor outlet) and the third opening 106 (indoor outlet) are respectively located on the opposite sides of the shell 10, which can ensure that the air outlet baffle 23 blocks the second air outlet 122 when the air inlet baffle 22 blocks the first air inlet 111, and can ensure that the air outlet baffle 23 blocks the first air outlet 121 when the air inlet blocks the second air inlet 112, which can improve the sealing of the passage, help increase the air inlet and outlet volume of the fan assembly, and improve the air outlet efficiency of the fan assembly.

[0104] like Figure 10-15 As shown, in some examples, the driving component drives the rotating component 20 to rotate between a first position and a second position. When the rotating component 20 rotates to the first position, the air inlet baffle 22 can block the second air inlet 112, and the air outlet baffle 23 can block the first air outlet 121, so that outdoor air can enter the first air inlet duct 116 through the first opening 101, and then enter the air inlet cavity 103 through the first air inlet 111, and then enter the air outlet cavity 104 through the connecting port 211, and then enter the second air outlet duct 128 through the second air outlet 122, and finally flow into the room through the third opening 106, so that air can be supplied to the room, and the outdoor air can be filtered to realize the supply of fresh air to the room.

[0105] When the rotating assembly 20 rotates to the second position, the air inlet baffle 22 can block the first air inlet 111, and the air outlet baffle 23 can block the second air outlet 122, so that the indoor air can enter the second air inlet duct 117 through the second opening 102, and then enter the air inlet cavity 103 through the second air inlet 112, and then enter the air outlet cavity 104 through the connecting port 211, and then enter the first air outlet duct 127 through the first air outlet 121, and finally flow to the outside through the first opening 101 to exhaust air to the outside, for example, the dirty air in the room can be discharged.

[0106] In other examples, when the rotating assembly 20 rotates to an intermediate position between the first position and the second position, the air inlet baffle 22 can block the first air inlet 111 to disconnect the air inlet cavity 103 and the first air inlet duct 116, and the air outlet baffle 23 can block the first air outlet 121 to disconnect the air outlet cavity 104 and the first air outlet duct 127, thereby achieving the closure of the first opening 101, that is, the rotating assembly 20 can close the first passage and the second passage at the same time, thereby achieving the separation of the outdoor space and the indoor space, preventing outdoor air from entering the room when the fan assembly is not supplying air to the room, for example, preventing cold air from flowing back into the room.

[0107] Alternatively, the air inlet baffle 22 can block the second air inlet 112 to disconnect the air inlet cavity 103 and the second air inlet duct 117, and the air outlet baffle 23 can block the second air outlet 122 to disconnect the air outlet cavity 104 and the second air outlet duct 128, thereby achieving the closure of the second opening 102.

[0108] In other examples, the projection of a portion of the air inlet baffle 22 on the partition plate 21 coincides with the projection of a portion of the air outlet baffle 23 on the partition plate 21, so that the air outlet baffle 23 can block the first air outlet 121 while the air inlet baffle 22 blocks the first air inlet 111, thereby disconnecting the air inlet cavity 103 from the first air inlet duct 116 and disconnecting the air outlet cavity 104 from the first air outlet duct 127, thereby achieving the closure of the first opening 101.

[0109] At the same time, the gap between the air inlet baffle 22 and the first air inlet 111 can be reduced, and the gap between the air outlet baffle 23 and the first air outlet 121 can be reduced, which can improve the closing effect of the first air inlet 111 and the second air outlet 122, and then improve the closing effect of the first opening 101 (outdoor outlet), thereby improving the separation effect of the outdoor space and the indoor space, and preventing outdoor air from flowing back into the room when the fan assembly does not deliver fresh air.

[0110] like Figure 10As shown, in some examples, the housing 10 has a first limit member 113 and a second limit member 114. When the rotating assembly 20 rotates to the first position, the air inlet baffle 22 can cooperate with the first limit member 113 to limit the rotating assembly 20, prevent the rotating assembly 20 from interfering with the components in the housing 10 due to excessive rotation, and improve the reliability of the fan assembly; when the rotating assembly 20 rotates to the second position, the air inlet baffle 22 can cooperate with the second limit member 114 to limit the rotating assembly 20, prevent the rotating assembly 20 from interfering with the components in the housing 10 due to excessive rotation, and improve the reliability of the fan assembly. That is, the first limit member 113 and the second limit member 114 can both be arranged in the air inlet cavity 103 to limit the movement of the air inlet baffle 22 in the rotation direction of the rotating assembly 20.

[0111] Alternatively, when the rotating component 20 rotates to the first position, the air outlet baffle 23 can cooperate with the first limiting member 113 to achieve the limitation of the rotating component 20, and when the rotating component 20 rotates to the second position, the air outlet baffle 23 can cooperate with the second limiting member 114 to achieve the limitation of the rotating component 20, that is, the first limiting member 113 and the second limiting member 114 can both be arranged in the air outlet cavity 104 to limit the movement of the air outlet baffle 23 in the rotation direction of the rotating component 20.

[0112] Of course, when the rotating assembly 20 rotates to the first position, the air inlet baffle 22 and the air outlet baffle 23 can simultaneously cooperate with the first limiting member 113 to achieve the limitation of the rotating assembly 20. When the rotating assembly 20 rotates to the second position, the air inlet baffle 22 and the air outlet baffle 23 can simultaneously cooperate with the second limiting member 114 to achieve the limitation of the rotating assembly 20. That is, the first limiting member 113 can be simultaneously set in the air inlet cavity 103 and the air outlet cavity 104, and the second limiting member 114 can be simultaneously set in the air inlet cavity 103 and the air outlet cavity 104 to simultaneously limit the movement of the air inlet baffle 22 and the air outlet baffle 23 in the rotation direction of the rotating assembly 20, which can improve the reliability of the limitation of the rotating assembly 20.

[0113] In some examples, the inner wall surface of the shell 10 may have a convex rib, which protrudes toward the center of the accommodating cavity. The convex rib can form a first limiting member 113, and then when the rotating assembly 20 rotates to the second position, the air inlet baffle 22 can abut against the convex rib to achieve the limitation of the rotating assembly 20; or, the convex rib can form a second limiting member 114, and then when the rotating assembly 20 rotates to the first position, the air inlet baffle 22 can abut against the convex rib to achieve the limitation of the rotating assembly 20; it can be understood that the first limiting member 113 and the second limiting member 114 can both be convex ribs for easy processing.

[0114] In some examples, the inner wall surface of the housing 10 may have a protrusion, which extends along the circumference of the accommodating cavity, and a limiting groove is formed at one end of the protrusion. The limiting groove can form a second limiting member 114, and then when the rotating assembly 20 rotates to the first position, the air inlet baffle 22 can be plugged into the limiting groove to achieve the limitation of the rotating assembly 20; or, the limiting groove can form a first limiting member 113, and then when the rotating assembly 20 rotates to the second position, the air inlet baffle 22 can be plugged into the limiting groove to achieve the limitation of the rotating assembly 20; it can be understood that the first limiting member 113 and the second limiting member 114 can both be limiting grooves, which can improve the limiting effect of the rotating assembly 20.

[0115] like Figure 10 、 Figure 14 and Figure 15 As shown, in some examples, the first limit member 113 and the second limit member 114 are both located in the air inlet cavity 103, and the two ends of the air inlet baffle 22 in the extension direction can respectively cooperate with the first limit member 113 and the second limit member 114. When the rotating assembly 20 rotates to the first position, the air inlet baffle 22 can cooperate with the first limit member 113. When the rotating assembly 20 rotates to the second position, the air inlet baffle 22 can cooperate with the second limit member 114, which can achieve the limitation of the rotating assembly 20 and prevent the rotating assembly 20 from interfering with the components in the outer casing 10 due to excessive rotation, thereby improving the reliability of the fan assembly.

[0116] like Figure 1 、 Figure 2 and Figure 11 As shown, in some examples, the housing 10 has a socket 115 for inserting the filter 50, and the first limit member 113 and the second limit member 114 can both be located on one side of the socket 115; of course, the actual position of the limit member can be determined based on actual design parameters, and the design parameters can be the size of the air inlet baffle 22, the position of the air inlet baffle 22 when the rotating assembly 20 rotates to the first position, or the position of the air inlet baffle 22 when the rotating assembly 20 rotates to the second position.

[0117] It should be noted that the first limit member 113 and the second limit member 114 can be located on opposite sides of the socket 115, that is, in the circumferential direction of the air inlet chamber 103, the socket 115 can be located between the first limit member 113 and the second limit member 114, so that the two limit members can limit the air inlet baffle 22 to prevent the air inlet baffle 22 from blocking the socket 115, thereby preventing the air inlet baffle 22 from interfering with the filter element 50, which can improve the reliability of the fan assembly and is beneficial for the operator to load and unload the filter element 50 when the fan assembly is working, thereby facilitating maintenance.

[0118] like Figure 9As shown, according to some embodiments of the present invention, the drive assembly further includes: a second drive motor 32, the second drive motor 32 is arranged on a side of the wind wheel 40 away from the partition plate 21 (such as Figure 9 The second drive motor 32 cooperates with the wind wheel 40, and the second drive motor 32 can drive the wind wheel 40 to rotate.

[0119] like Figure 13 As shown, a motor mounting portion 124 is provided on the second shell 12, and the motor mounting portion 124 is located on the bottom wall of the air outlet chamber 104. The motor mounting portion 124 has a mounting hole and a positioning groove. The second drive motor 32 can be fixedly connected to the motor mounting portion 124 through the mounting hole to achieve the installation of the second drive motor 32. At the same time, a part of the second drive motor 32 can be plugged into the positioning groove to achieve the positioning of the installation of the second drive motor 32 and improve the stability of the installation of the second drive motor 32. Therefore, the output shaft of the second drive motor 32 is connected to the wind wheel 40, which can directly drive the wind wheel 40 to rotate.

[0120] It should be noted that a wire outlet hole 125 is provided on the bottom wall of the second shell 12 , and the second drive motor 32 can be electrically connected to the power supply through a cable, wherein the cable can pass through the wire outlet hole 125 to connect the second drive motor 32 and the power supply.

[0121] According to an embodiment of the present invention, the fresh air module 100 of the air conditioner includes: a fan assembly and a filter 50. The filter 50 is detachably arranged in the fan assembly, which is convenient for replacement and helps to reduce maintenance costs. By adopting the above-mentioned fan assembly, passages in multiple directions can be formed in the fresh air module 100, which can enrich the working mode of the fresh air module 100 and improve the user experience.

That is, by arranging the wind wheel 40 and the filter element 50 separately in two chambers, interference between the wind wheel 40 and the filter element 50 can be prevented, which is beneficial to improving the reliability of the operation of the wind wheel 40 and the service life of the filter element 50.

[0123] like Figure 17 As shown, in some examples, the filter element 50 includes a filter body 51 and a positioning handle 52. A socket 115 is provided on the side wall of the air inlet cavity 103. The filter body 51 can be extended into the air inlet cavity 103 through the socket 115. At least a portion of the positioning handle 52 is in the width direction (such as Figure 17The dimension in the left and right directions (as shown) is larger than the dimension of the socket 115, so that the positioning handle 52 can abut against the first shell 11 when the filter body 51 enters the air inlet chamber 103, which can realize the positioning of the installation of the filter element 50 and is beneficial to improving the stability of the installation of the filter element 50.

[0124] It should be noted that if Figure 17 and Figure 18 As shown, a mounting member 105 is provided in the air inlet chamber 103, and the mounting member 105 can be connected to the first shell 11. The mounting member 105 has a mounting port, and the filter body 51 has a mounting boss 511. After the filter body 51 extends into the air inlet chamber 103 through the socket 115, the mounting boss 511 can be snap-fitted with the mounting port to realize the installation of the filter element 50.

[0125] like Figure 14 As shown, in some examples, the side of the partition plate 21 facing the air inlet cavity 103 (such as Figure 14 The left side shown in the figure is provided with a sealing ring, and the partition plate 21 can be sealed with the frame of the filter element 50 (for example, the filter body 51) through the sealing ring, so that the air in the air inlet chamber 103 can fully flow through the filter mesh in the filter element 50 and then enter the air outlet chamber 104, which can improve the filtering effect of the air and improve the user experience.

[0126] According to an embodiment of the present invention, the air conditioner includes a fan assembly; or, includes a fresh air module 100 of the air conditioner. By adopting the above-mentioned fan assembly or the above-mentioned fresh air module 100 of the air conditioner, passages in multiple directions can be formed in the air conditioner, which can enrich the working mode of the air conditioner and improve the user experience.
