Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0060] Reference below Figure 1-Figure 23 A fan assembly according to an embodiment of the present invention is described.

[0061] like Figure 1-Figure 23 As shown, the fan assembly according to an embodiment of the present invention includes: a housing 10, a rotating assembly 20, and a driving assembly. The housing 10 has an air inlet cavity 103 and an air outlet cavity 104. The air inlet cavity 103 has a first air inlet 111 and a second air inlet 112. The air outlet cavity 104 has a first air outlet 121 and a second air outlet 122.

[0062] The rotating assembly 20 is arranged in the housing 10, and the rotating assembly 20 can rotate in the housing 10. The rotating assembly 20 includes a partition plate 21, an air inlet baffle 22 and an air outlet baffle 23. The partition plate 21 is located between the air inlet cavity 103 and the air outlet cavity 104. The partition plate 21 is provided with a communication port 211, and the communication port 211 can connect the air inlet cavity 103 and the air outlet cavity 104. The air inlet baffle 22 is provided on one side of the partition plate 21 facing the air inlet cavity 103 (such as Figure 9 The left side shown in FIG2 is conducive to the air inlet baffle 22 shielding the first air inlet 111 or the second air inlet 112, and the air outlet baffle 23 is arranged on the side of the partition plate 21 facing the air outlet cavity 104 (as shown in FIG22 ). Figure 9 The right side shown in the figure) is conducive to the air outlet baffle 23 shielding the first air outlet 121 or the second air outlet 122.

[0063] The driving assembly is arranged on the outer shell 10, and the driving assembly is connected to the rotating assembly 20. The driving assembly can drive the rotating assembly 20 to rotate between a first position and a second position. When the rotating assembly 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 air can 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 flow out through the second air outlet 122, thereby forming a first passage in the outer shell 10.

[0064] 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 air can 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 flow out through the first air outlet 121. A second passage can be formed in the outer shell 10, that is, by driving the rotating assembly 20 to rotate, air can flow in different passages, which is conducive to switching the working mode of the fan assembly and facilitates 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 arranged on the partition plate 21, so that the rotating assembly 20 can close different air inlets and different air outlets during rotation, so that air can flow into the outer shell 10 through different air inlets and flow out of the outer shell 10 through different air outlets, so as to form passages in multiple directions in the outer shell 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] According to some embodiments of the present invention, 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, and the air outlet baffle 23 can block the first air outlet 121, or the air inlet baffle 22 can block the second air inlet 112, and the air outlet baffle 23 can block the second air outlet 122, that is, the rotating assembly 20 can close the first passage and the second passage at the same time, thereby achieving separation of the outdoor space and the indoor space, and preventing the outdoor air and the indoor air from communicating when the fan assembly is not working.

[0067] It can be understood that when the rotating component 20 rotates to a certain position, the rotating component 20 can simultaneously close the above-mentioned multiple passages. Compared with setting a wind valve in each passage and each wind valve requires a separate motor drive, it can reduce the motion mechanism in the fan assembly, simplify the structure of the fan assembly, improve the space utilization of the fan assembly, help reduce the volume of the fan assembly, realize the miniaturization of the fan assembly, and improve the reliability of the fan assembly, and help reduce the cost of the fan assembly.

[0068] like Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, in some examples, the housing 10 may have an outdoor port (e.g. Figure 7 The first opening 101 shown) and the indoor opening (as shown Figure 1The first air inlet 111 and the first air outlet 121 both correspond to the position of the outdoor outlet, that is, the first air inlet 111 is used to connect the outdoor space and the air inlet cavity 103, and the first air outlet 121 is used to connect the outdoor space and the air outlet cavity 104. The indoor outlet is used to connect the indoor space and the chamber in the shell 10, and the second air inlet 112 and the second air outlet 122 both correspond to the position of the indoor outlet, that is, the second air inlet 112 is used to connect the indoor space and the air inlet cavity 103, and the second air outlet 122 is used to connect the indoor space and the air outlet cavity 104.

[0069] Among them, 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 air inlet chamber 103 through the first air inlet 111, and then enter the air outlet chamber 104 through the connecting port 211, and then flow into the room through the second air outlet 122, 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.

[0070] When the rotating component 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 air inlet chamber 103 through the second air inlet 112, and then enter the air outlet chamber 104 through the connecting port 211, and then flow to the outside through the first air outlet 121 to exhaust air to the outside, for example, the dirty air in the room can be discharged; when the rotating component 20 rotates to the middle position, the air inlet baffle 22 can block the first air inlet 111, and the air outlet baffle 23 can block the first air outlet 121 to achieve the closure of the entire outdoor outlet, which can prevent outdoor air from entering the room when the fan component does not deliver fresh air, and can prevent cold air from flowing back, thereby reducing the probability of condensation in the fan component.

[0071] In other examples, the first air inlet 111 and the first air outlet 121 both correspond to the indoor outlet position, that is, the first air inlet 111 is used to connect the indoor space and the air inlet chamber 103, and the first air outlet 121 is used to connect the indoor space and the air outlet chamber 104; the second air inlet 112 and the second air outlet 122 both correspond to the outdoor outlet position, that is, the second air inlet 112 is used to connect the outdoor space and the air inlet chamber 103, and the second air outlet 122 is used to connect the outdoor space and the air outlet chamber 104.

[0072] Among them, 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 the indoor air can enter the air inlet chamber 103 through the first air inlet 111, and then enter the air outlet chamber 104 through the connecting port 211, and then flow to the outside through the second air outlet 122 to exhaust air to the outside, for example, the dirty air in the room can be discharged.

[0073] When the rotating component 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 outdoor air can enter the air inlet chamber 103 through the second air inlet 112, and then enter the air outlet chamber 104 through the connecting port 211, and then flow into the room through the first air outlet 121, 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.

[0074] When the rotating assembly 20 rotates to the middle position, the air inlet baffle 22 can block the second air inlet 112, and the air outlet baffle 23 can block the second air outlet 122, so as to close the entire indoor opening, prevent cold air from flowing back into the room, and reduce the probability of condensation in the fan assembly.

[0075] like Figure 7 、 Figure 8 、 Figure 9 and Figure 11 As shown, according to some embodiments of the present invention, in the rotation axis of the rotating component 20 (such as Figure 9 In the left and right directions shown in FIG, the first air inlet 111 is located on one side of the first air outlet 121 (as shown in FIG. Figure 11 The first air inlet 111 and the first air outlet 121 are connected to each other.

[0076] Among them, the first part of the air inlet baffle 22 and the second part of the air outlet baffle 23 correspond in position, that is, the projection of a part of the air inlet baffle 22 on the partition plate 21 coincides with the projection of a part of the air outlet baffle 23 on the partition plate 21, and the sum of the area of ​​the first part and the area of ​​the second part is not less than the sum of the area of ​​the first air inlet 111 and the area of ​​the first air outlet 121. This can ensure that the air inlet baffle 22 fully blocks the first air inlet 111 when the rotating assembly 20 rotates to the middle position, and can ensure that the air outlet baffle 23 fully blocks the first air outlet 121 when the rotating assembly 20 rotates to the middle position, which can improve the closing effect of the outdoor opening and improve the separation effect of the outdoor space and the indoor space.

[0077] Alternatively, in the rotational axis of the rotating assembly 20, the second air inlet 112 is located on one side of the second air outlet 122 (eg, Figure 11The left side is shown), and the second air inlet 112 and the second air outlet 122 are connected to each other, the first part of the air inlet baffle 22 and the second part of the air outlet baffle 23 correspond in position, the sum of the area of ​​the first part and the area of ​​the second part is not less than the sum of the area of ​​the second air inlet 112 and the area of ​​the second air outlet 122, which can ensure that the air inlet baffle 22 completely blocks the second air inlet 112 when the rotating component 20 rotates to the middle position, and can ensure that the air outlet baffle 23 completely blocks the second air outlet 122 when the rotating component 20 rotates to the middle position, which can improve the closing effect of the indoor opening and improve the separation effect of the outdoor space and the indoor space.

[0078] like Figure 5 、 Figure 6 、 Figure 9 、 Figure 17 and Figure 19 As shown, according to some embodiments of the present invention, 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, the air outlet baffle 23 can be provided with meshing teeth 2311, the gear 30 is engaged with the meshing teeth 2311, 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; or, the air inlet baffle 22 can be provided with meshing teeth 2311, the gear 30 is engaged with the meshing teeth 2311, and 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 inlet baffle 22.

[0079] like Figure 9 and Figure 10 As shown, according to some embodiments of the present invention, the air outlet baffle 23 includes a first shielding section 231 and a second shielding section 232, the first shielding section 231 extends along the outer periphery of the partition plate 21, the second shielding section 232 is located on the inner side of the first shielding section 231, one end of the second shielding section 232 is connected to the first shielding section 231, the other end of the second shielding section 232 is arranged at an interval from the first shielding section 231, and the other end of the second shielding section 232 is transitionally connected to the first shielding section 231 through a volute tongue section 233, and the side of the first shielding section 231 facing away from the second shielding section 232 can be provided with meshing teeth 2311, thereby, the first drive motor 31 and the gear 30 can be arranged outside the rotating assembly 20, which can reduce the probability of the first drive motor 31 and the gear 30 interfering with the airflow, which is beneficial to reducing the flow resistance of air inside the fan assembly and improving the working efficiency of the fan assembly.

[0080] 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.

[0081] like Figure 7-10 As shown, in some examples, a portion of the first shielding segment 231 away from the end of the volute tongue segment 233 is located in the rotation axis of the air inlet baffle 22 in the rotating assembly 20 (eg Figure 10 On one side (as shown in the left and right directions) Figure 10 As shown in the right side), that is, a portion of the air inlet baffle 22 and a portion of the air outlet baffle 23 overlap in the rotation axis of the rotating assembly 20 to form an overlapping section, and the overlapping section is in the width direction (such as Figure 10 The dimension in the left and right directions (as shown) is larger than the maximum width dimension of the air inlet baffle 22 and the air outlet baffle 23, which can ensure that the overlapping section fully blocks the first air inlet 111 and the first air outlet 121 when the rotating assembly 20 rotates to a certain position (for example, the middle position), and can improve the closing effect of the first air inlet 111 and the second air outlet 122, and prevent outdoor air from flowing back into the room.

[0082] It can be understood that the overlapping section can simultaneously block the first air inlet 111 and the first air outlet 121. Compared with the scheme in which the first air inlet 111 and the first air outlet 121 are staggered in the rotation axis of the rotating component 20, and the air inlet baffle 22 and the air outlet baffle 23 are staggered in the rotation axis of the rotating component 20, when the overlapping section simultaneously closes the first air inlet 111 and the first air outlet 121, the overlapping section can reduce the gap between the air inlet baffle 22 and the first air inlet 111, and at the same time reduce the gap between the air outlet baffle 23 and the first air outlet 121, thereby improving the closing effect of the first air inlet 111 and the second air outlet 122.

[0083] like Figure 6-Figure 8 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 6The first shell 11 and the second shell 12 are fixedly connected by fasteners, so that the partition plate 21 of the rotating assembly 20 can separate the air inlet chamber 103 and 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, and 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 chamber 104 and a second air outlet 122 on the other side of the air outlet chamber 104.

[0084] like Figure 1 and Figure 7 As shown, according to some embodiments of the present invention, the housing 10 has a first opening 101 and a second opening 102, the first air inlet 111 and the first air outlet 121 are respectively connected to the first opening 101, the second air inlet 112 and the second air outlet 122 are respectively connected to the second opening 102, the first opening 101 can be connected to the outdoor side, and the second opening 102 can be connected to the indoor side.

[0085] When the rotating assembly 20 rotates to the first position, the air inlet baffle 22 blocks the second air inlet 112, and the air outlet baffle 23 blocks the first air outlet 121, so that outdoor air can enter the air inlet chamber 103 through the first opening 101 and the first air inlet 111 in turn, and then enter the air outlet chamber 104 through the connecting port 211, and then enter the room through the second air outlet 122 and the second opening 102 in turn to deliver fresh air to the room.

[0086] When the rotating assembly 20 rotates to the second position, the air inlet baffle 22 blocks the first air inlet 111, and the air outlet baffle 23 blocks the second air outlet 122, so that the indoor air can enter the air inlet chamber 103 through the second opening 102 and the second air inlet 112 in turn, then enter the air outlet chamber 104 through the connecting port 211, and then enter the room through the first air outlet 121 and the first opening 101 in turn to be exhausted to the outdoors.

[0087] When the rotating assembly 20 rotates to an intermediate position between the first position and the second position, the air inlet baffle 22 blocks the first air inlet 111, and the air outlet baffle 23 blocks the first air outlet 121, so as to close the first opening 101 and prevent outdoor air from entering the room when the fan assembly stops delivering fresh air.

[0088] like Figure 5 、 Figure 6 and Figure 17As shown, according to some embodiments of the present invention, the fan assembly also includes a wind wheel 40, which is arranged in the air outlet chamber 104, and the air outlet baffle 23 is located on the periphery of the wind wheel 40. 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.

[0089] It should be noted that, in the direction of rotation of the wind wheel 40, the distance between the inner wall surface of the second blocking 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 can be gradually increased, which is beneficial to reducing the probability of turbulence in the fan assembly, thereby reducing the flow resistance of the air, increasing the air output of the fan assembly, and improving the air output efficiency of the fan assembly. Specifically, 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.

[0090] like Figure 6 and Figure 8 As shown, in some examples, the drive assembly includes: a first drive motor 31 and a second drive motor 32, the first drive motor 31 is used to drive the rotating assembly 20 to rotate, specifically, a gear mounting portion 123 is provided on the second shell 12, the gear mounting portion 123 is located outside the air outlet chamber 104, the gear mounting portion 123 has a groove, and a gear cover 33 can be provided at the open mouth of the groove, the gear 30 can be placed in the groove, and the gear cover 33 is snap-fitted with the open mouth of the groove, the first drive motor 31 is fixedly connected to the gear cover 33, and the output shaft of the first drive motor 31 passes through the gear cover 33 and is connected to the gear 30, the side wall of the air outlet chamber 104 is provided with an avoidance opening, the gear 30 engages with the meshing teeth 2311 on the air outlet baffle 23 through the avoidance opening, 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.

[0091] The second drive motor 32 is used to drive the wind wheel 40 to rotate. Specifically, a motor mounting portion 124 is provided on the second shell 11, 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. Thus, 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; 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.

[0092] like Figure 7 As shown, according to some embodiments of the present invention, a first limit member 113 and a second limit member 114 are provided in the housing 10. 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.

[0093] 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.

[0094] 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.

[0095] like Figure 7 As shown, in some examples, the cavity in the shell 10 is a accommodating cavity, which includes an air inlet cavity 103 and an air outlet cavity 104. 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 may form a first limiting member 113, and then when the rotating assembly 20 rotates to the second position, the air inlet baffle 22 may abut against the convex rib to achieve the limitation of the rotating assembly 20; or, the convex rib may form a second limiting member 114, and then when the rotating assembly 20 rotates to the first position, the air inlet baffle 22 may 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.

[0096] like Figure 7 As shown, in some examples, the inner wall surface of the shell 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 component 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 component 20; or, the limiting groove can form a first limiting member 113, and then when the rotating component 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 component 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 component 20.

[0097] like Figure 7As 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.

[0098] 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.

[0099] like Figure 6 As shown, according to some embodiments of the present invention, a wind wheel 40 can be provided in the air outlet chamber 104, and a filter element 50 can be provided in the air inlet chamber 103. That is, by separately arranging the wind wheel 40 and the filter element 50 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.

[0100] like Figure 7 、 Figure 20 and Figure 21 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 6 The 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.

[0101] It should be noted that a mounting member 105 is provided in the air inlet chamber 103, and the mounting member 105 is 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 is extended 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.

[0102] It should be added that, 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, that is, the two limit members can limit the air inlet baffle 22, thereby preventing the air inlet baffle 22 from blocking the socket 115, and further preventing the air inlet baffle 22 from interfering with the filter element 50, thereby improving the reliability of the fan assembly and facilitating the operator to load and unload the filter element 50 when the fan assembly is working, thereby facilitating maintenance.

[0103] like Figure 9 and Figure 20 As shown, in some examples, the side of the partition plate 21 facing the air inlet cavity 103 (such as Figure 9 The left side shown in the figure is provided with a sealing ring 212, 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 212, 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.

[0104] It should be noted that when the rotating component 20 rotates to the middle position, the rotating component 20 can simultaneously close the first air inlet 111 and the first air outlet 121, that is, the rotating component 20 can close the entire first opening 101, which can prevent outdoor air from flowing through the filter element 50 and entering the room when the fresh air module 100 stops delivering fresh air, which is beneficial to improving the service life of the filter element 50.

[0105] 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, 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.

Figure 16 As shown, when the rotating assembly 20 rotates to the second position, the ray A3 is tangent to one end of the air outlet baffle 23 (eg, the volute tongue segment 233 ).

[0111] When the air conditioner is in the initial state, for example, Figure 11 and Figure 12 As shown, the rotating assembly 20 is in the first position, the air inlet baffle 22 blocks the second air inlet 112, the air outlet baffle 23 blocks the first air outlet 121, and the second drive motor 32 can drive the wind wheel 40 to rotate to generate negative pressure in the air outlet cavity 104; at this time, as shown in FIG.

After the outdoor air is filtered, the air conditioner can supply fresh air to the room to realize the fresh air supply function of the air conditioner.

[0112] like Figure 5 As shown, the first drive motor 31 can drive the rotating assembly 20 to rotate β° clockwise to the middle position through the gear 30, as shown in FIG.
