[0007] The fresh air module of the embodiment of the present disclosure sets a first cover plate at the first part of the maintenance opening and sets a fixing frame on the first cover plate. By arranging the second end of the filter screen assembly at the second part of the maintenance opening and using the detachable engagement between the filter screen assembly and the fixing frame, the filter screen assembly can be taken out of and inserted into the housing through the second part of the maintenance opening, realizing the replacement of the filter screen assembly without removing the first cover plate, reducing the difficulty of replacing the filter screen assembly, and when replacing the filter screen assembly, only need to pull the filter screen assembly to disengage it from the fixing frame, which is simple and convenient to operate.

[0008] In some embodiments, the filter assembly includes a filter support and a filter. The filter is disposed on the filter support, and the filter support is detachably engaged with the fixed frame. A first end of the filter support is adjacent to the diversion ring, and a second end of the filter support is disposed within a second portion of the inspection opening.

[0009] In this embodiment, by disposing the filter on the filter support, with the first end of the filter support adjacent to the diversion ring and the second section of the filter support disposed within the second portion of the inspection opening, and using the detachable engagement between the filter support and the fixed frame, it is convenient to take out and install the filter support from the housing through the second portion of the inspection opening, realizing the replacement of the filter without removing the first cover plate and reducing the difficulty of filter replacement.

[0010] In some embodiments, the filter support includes an end plate and a filter frame. The filter frame is detachably engaged with the fixed frame. The filter is disposed within the filter frame, and the end plate is provided at one end of the filter frame and is located within the second portion of the inspection opening.

[0011] In this embodiment, by disposing the filter frame within the housing and detachably engaging it with the fixed frame, and connecting the end plate to the filter frame and disposing it within the second portion of the inspection opening, such that one end of the end plate away from the filter frame is exposed, it is convenient to operate the exposed portion of the end plate to disengage or engage the filter frame with the fixed frame, thereby realizing the replacement of the filter.

[0012] In some embodiments, at least a portion of the end plate presses against the fixed frame. By pressing at least a portion of the end plate against the fixed frame, on the one hand, it is convenient to determine whether the filter frame and the fixed frame are installed in place, and on the other hand, it is beneficial to improve the connection stability between the fixed frame and the filter assembly.

[0013] In some embodiments, the filter frame is provided with a buckle for clamping the filter. Through the setting of the buckle, it is convenient to clamp the filter on the filter frame and improve the filter replacement efficiency.

[0014] In some embodiments, the end plate is provided with a handle for taking out and installing the filter assembly into the housing. Through the setting of the handle, it is convenient to operate the end plate, and thus it is convenient to take out and install the filter assembly into the housing.

[0015] In some embodiments, the end plate is provided with a through hole for passing through a fastener to detachably connect the end plate to the housing. By providing a through hole on the end plate, it is convenient for the fastener to pass through the through hole and connect with the housing, realizing the detachable connection between the end plate and the housing while improving the stability of the end plate.

[0016] In some embodiments, the end plate and the filter frame are integrally formed. By integrally forming the end plate and the filter frame, it is beneficial to improve the structural strength of the filter support and facilitate the manufacture of the filter support.

[0017] In some embodiments, the first end of the filter screen support extends towards the direction of the diversion ring and is inclined in the direction close to the first cover plate. By arranging the filter screen support obliquely, it is convenient for the filter screen to filter the air flow while reducing the flow resistance of the air flow.

[0018] In some embodiments, the blower inlet and the maintenance opening are arranged opposite to each other in the first direction, the inclination angle of the filter screen support relative to the first direction is α, and 20° ≤ α ≤ 70°.

[0019] In this embodiment, by limiting the included angle between the filter screen support and the first direction, on the one hand, it avoids too large an included angle, which increases the air flow resistance and reduces the air volume; on the other hand, it avoids too small an included angle, so that the exposed part of the filter screen support is not within the maintenance area, increasing the difficulty of replacing the filter screen assembly, and realizing a large air volume while reducing the difficulty of replacing the filter screen.

[0020] In some embodiments, the fixing frame includes a first fixing plate and a second fixing plate, the first fixing plate and the second fixing plate are arranged at intervals, the filter screen assembly is located between the first fixing plate and the second fixing plate, and at least one of the first fixing plate and the second fixing plate is detachably engaged with the filter screen assembly.

[0021] In this embodiment, the filter screen assembly is arranged between the first fixing plate and the second fixing plate, and the fixing plate is detachably engaged with the filter screen assembly, which is convenient for the assembly of the filter screen assembly and the fixing frame while improving the convenience of taking out and installing the filter screen assembly from the shell.

[0022] In some embodiments, the fixing frame is provided with a first clamping portion, the filter screen assembly is provided with a second clamping portion, one of the first clamping portion and the second clamping portion is a concave portion, the other of the first clamping portion and the second clamping portion is a convex portion, and the convex portion is detachably engaged with the concave portion.

[0023] In this embodiment, by providing a first clamping portion on the fixing frame and a second clamping portion on the filter screen assembly, the clamping and detachment of the fixing frame and the filter screen assembly are realized through the clamping and detachment of the first clamping portion and the second clamping portion, and the operation is simple and convenient.

[0024] In some embodiments, the fixing frame is provided with a first guiding portion, the first guiding portion is arranged at an interval from the first clamping portion, the filter screen assembly is provided with a second guiding portion, the second guiding portion is arranged at an interval from the second clamping portion, and the first guiding portion and the second guiding portion are movably matched relatively to guide the filter screen assembly when taking out and installing the filter screen assembly.

[0025] In this embodiment, a first guiding portion is provided on the fixing frame, and a second guiding portion is provided on the filter screen assembly. The second guiding portion moves along the extending direction of the first guiding portion to guide the moving direction of the filter screen assembly, thereby improving the replacement efficiency of the filter screen assembly.

[0026] In some embodiments, one of the first guiding portion and the second guiding portion is a convex post, and the other of the first guiding portion and the second guiding portion is a groove. When the filter screen assembly is engaged with the fixing frame, the convex post is fitted into the groove.

[0027] In this embodiment, through the cooperation of the convex post and the groove, on the one hand, the filter screen assembly can be guided when the filter screen assembly is taken out and installed, and on the other hand, the filter screen assembly can be limited to improve the installation accuracy of the filter screen assembly.

[0028] In some embodiments, the fixing frame is provided with a convex rib, and the convex rib is arranged at an interval from the first clamping portion and is located on a side of the first clamping portion away from the first guiding portion, and the convex rib abuts against the filter screen assembly.

[0029] In this embodiment, through the arrangement of the convex rib, the contact area between the filter screen assembly and the fixing frame is reduced, and thus the resistance when the filter screen assembly moves relative to the fixing frame is reduced, making the process of taking out and installing the filter screen assembly from the fixing frame smoother and improving the replacement efficiency.

[0030] In some embodiments, the fixing frame is provided with a limiting member, and the limiting member is located on a side of the first clamping portion away from the first guiding portion, and the limiting member is arranged at an interval from the filter screen assembly.

[0031] In this embodiment, by providing a limiting member on a side of the first clamping portion away from the first guiding portion and arranging the limiting member at an interval from the filter screen assembly, the moving range of the filter screen assembly can be limited when the second guiding portion of the filter screen assembly is not assembled with the first guiding portion of the fixing frame, thereby improving the efficiency of taking out and installing the filter screen assembly from the fixing frame.

[0032] In some embodiments, the first cover plate and the fixing frame are integrally formed. Thus, it is beneficial to improve the structural strength of the first cover plate and the fixing frame and facilitate the manufacture of the first cover plate and the fixing frame.

[0033] In some embodiments, the fresh air module further includes a second cover plate, and the second cover plate is detachably arranged on the housing and covers a part of the second part of the maintenance opening, so that the filter screen assembly can be taken out and installed into the housing from a part of the maintenance opening located between the first cover plate and the second cover plate.

[0034] In this embodiment, a part of the second part of the maintenance opening is covered by the second cover plate, and another part of the second part of the maintenance opening is covered by the filter assembly, so that the filter assembly can be taken out and installed between the first cover plate and the second cover plate, realizing the replacement of the filter assembly without removing the first cover plate and the second cover plate.

[0035] In some embodiments, one end of the fixing frame away from the first cover plate abuts against the guide ring. By abutting one end of the fixing frame away from the first cover plate against the guide ring, on the one hand, it prevents air flow from passing through the gap between the fixing frame and the guide ring, and on the other hand, it improves the stability of the fixing frame.

[0036] In some embodiments, the fresh air module further includes a rectifying member. The guide ring has a guide opening, and the rectifying member is disposed in the guide opening and completely covers the guide opening. The rectifying member includes a first grid and a second grid formed by rib strips. The first grid includes a plurality of first through holes, the second grid includes a plurality of second through holes, and the flow area of the first through holes is larger than the flow area of the second through holes.

[0037] In this embodiment, by providing a rectifying member in the guide opening, the air flow passing through the guide opening is rectified by the plurality of first through holes of the first grid and the plurality of second through holes of the second grid. By setting the flow area of the first through holes to be larger than the flow area of the second through holes, the first grid can reduce the air volume attenuation while rectifying the air flow, and the second grid can better rectify the air flow with high turbulence, ensuring no obvious attenuation of the air volume while improving the rectifying effect and reducing the air flow noise, thereby improving the user experience.

[0038] In some embodiments, the rib strips include a plurality of first rib strips, a plurality of second rib strips and partition rib strips. The plurality of first rib strips are connected to each other to form a plurality of the first through holes, the plurality of second rib strips are connected to each other to form a plurality of the second through holes, and the partition rib strips are disposed between the first grid and the second grid.

[0039] In this embodiment, through the arrangement of connecting the plurality of first rib strips to each other, connecting the plurality of second rib strips to each other, and connecting the partition rib strips to the first rib strips and the second rib strips, the arrangement density of the first through holes and the second through holes can be increased on the basis of ensuring that the rectifying member has sufficient structural strength, improving the rectifying effect.

[0057] The embodiments of the present disclosure will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as a limitation to the present disclosure.

[0058] The following combination of attached Figures 1 to 5 The fresh air module according to the embodiment of the present disclosure will be described in detail.

[0059] The fresh air module of the embodiments of the present disclosure includes a housing 1, a fan 2, a guide ring 3, a first cover plate 41, a fixing bracket 5, and a filter assembly 6. The housing 1 is provided with a maintenance opening 11. The fan 2 is disposed inside the housing 1, and the fan 2 has a fan inlet 21 opposite to the maintenance opening 11. The guide ring 3 is disposed inside the housing 1 and at the fan inlet 21. The first cover plate 41 is detachably disposed on the housing 1 to cover a first part of the maintenance opening 11. The fixing bracket 5 is located inside the housing 1 and disposed on the first cover plate 41. The filter assembly 6 is disposed inside the housing 1 for filtering the air entering the fan inlet 21. The filter assembly 6 is detachably engaged with the fixing bracket 5. A first end of the filter assembly 6 is adjacent to the guide ring 3, and a second end of the filter assembly 6 is located at a second part of the maintenance opening 11.

[0060] In the fresh air module of the embodiments of the present disclosure, a first cover plate 41 is provided at a first part of the maintenance opening 11, and a fixing bracket 5 is provided on the first cover plate 41. By disposing the second end of the filter assembly 6 at the second part of the maintenance opening 11 and using the detachable engagement between the filter assembly 6 and the fixing bracket 5, the filter assembly 6 can be taken out of and inserted into the housing 1 through the second part of the maintenance opening 11. The replacement of the filter assembly 6 can be realized without removing the first cover plate 41, which reduces the difficulty of replacing the filter assembly 6. Moreover, when replacing the filter assembly 6, only by pulling the filter assembly 6 to disengage it from the fixing bracket 5, the operation is simple and convenient.

[0061] Specifically, as Figures 1 - 4 shown, the lower end of the housing 1 is provided with a maintenance opening 11. The fan inlet 21 is located at the lower end of the fan 2 and is arranged opposite to the maintenance opening 11 in the up-down direction. The guide ring 3 is disposed at the fan inlet 21 at the lower end of the fan 2. The first part and the second part of the maintenance opening 11 are adjacent to each other in the front-back direction and are integrated. The first cover plate 41 covers the first part of the maintenance opening 11, and the fixing bracket 5 is connected to the upper end of the first cover plate 41.

[0062] The filter assembly 6 is detachably engaged with the fixing bracket 5. When the filter assembly 6 is engaged with the fixing bracket 5, the upper end of the filter assembly 6 is adjacent to the guide ring 3, and the lower end of the filter assembly 6 is located at the second part of the maintenance opening 11, that is, the filter assembly 6 is installed inside the housing 1 so that the filter assembly 6 can filter the air entering the fan inlet 21; when the filter assembly 6 is disengaged from the fixing bracket 5, it is convenient to take out the filter assembly 6 from the housing 1 through the second part of the maintenance opening 11 to realize the replacement of the filter assembly 6.

[0063] In some embodiments, the filter assembly 6 includes a filter bracket 61 and a filter 62. The filter 62 is disposed on the filter bracket 61. The filter bracket 61 is detachably engaged with the fixing bracket 5. A first end of the filter bracket 61 is adjacent to the guide ring 3, and a second end of the filter bracket 61 is disposed inside the second part of the maintenance opening 11.

[0064] In this embodiment, the filter screen 62 is arranged on the filter screen support 61. The first end of the filter screen support 61 is adjacent to the diversion ring 3, and the second section of the filter screen support 61 is arranged in the second part of the inspection opening 11. By detachably engaging the filter screen support 61 with the fixing frame 5, it is convenient to take out and install the filter screen support 61 from the housing 1 through the second part of the inspection opening 11, realizing the replacement of the filter screen 62 without removing the first cover plate 41 and reducing the difficulty of replacing the filter screen 62.

[0065] Optionally, the connection between the filter screen 62 and the filter screen support 61 is detachable, facilitating the replacement of the filter screen 62 after taking out the filter screen support 61 from the housing 1.

[0066] In some embodiments, the filter screen support 61 includes an end plate 611 and a filter screen frame 612. The filter screen frame 612 is detachably engaged with the fixing frame 5, the filter screen 62 is arranged in the filter screen frame 612, and the end plate 611 is arranged at one end of the filter screen frame 612 and located in the second part of the inspection opening 11.

[0067] In this embodiment, by arranging the filter screen frame 612 in the housing 1 and detachably engaging it with the fixing frame 5, and connecting the end plate 611 to the filter screen frame 612 and arranging it in the second part of the inspection opening 11, the end of the end plate 611 far from the filter screen frame 612 is exposed, facilitating the separation or engagement of the filter screen frame 612 and the fixing frame 5 by operating the exposed part of the end plate 611, and further realizing the replacement of the filter screen 62.

[0068] Specifically, as Figure 2 shown, the end plate 611 is detachably connected to the housing 1 to cover the second part of the inspection opening 11. The upper end of the end plate 611 is connected to the lower end of the filter screen frame 612, and the lower end of the end plate 611 is exposed. By pulling the end plate 611 downward, the filter screen frame 612 is separated from the fixing frame 5.

[0069] In some embodiments, at least part of the end plate 611 presses on the fixing frame 5. By pressing at least part of the end plate 611 on the fixing frame 5, on the one hand, it is convenient to determine whether the filter screen frame 612 and the fixing frame 5 are installed in place, and on the other hand, it is beneficial to improve the connection stability between the fixing frame 5 and the filter screen assembly 6.

[0070] Specifically, as Figure 3 shown, the upper end of the front side of the end plate 611 presses on the fixing frame 5 to achieve a sealed connection between the end plate 611 and the fixing frame 5, preventing the air flow in the housing 1 from flowing out of the housing 1 through the gap between the fixing frame 5 and the end plate 611.

[0071] In some embodiments, as Figure 4 shown, the filter screen frame 612 is provided with a buckle 6121 for clamping the filter screen 62. Through the arrangement of the buckle 6121, it is convenient to clamp the filter screen 62 on the filter screen frame 612 and improve the replacement efficiency of the filter screen 62.

[0072] In some embodiments, as Figure 4 shown, the end plate 611 is provided with a handle 6111 for taking out and inserting the filter assembly 6 into the housing 1. By providing the handle 6111, it is convenient to operate the end plate 611, and thus it is convenient to take out and insert the filter assembly 6 into the housing 1.

[0073] Optionally, a recess is formed on the lower end surface of the end plate 611 to form the handle 6111.

[0074] In some embodiments, as Figure 4 shown, the end plate 611 is provided with a through hole 6112 for passing through a fastener to detachably connect the end plate 611 to the housing 1. By providing the through hole 6112 on the end plate 611, it is convenient for the fastener to pass through the through hole 6112 and connect to the housing 1, realizing the detachable connection between the end plate 611 and the housing 1 while improving the stability of the end plate 611.

[0075] In some embodiments, the end plate 611 and the filter frame 612 are integrally formed. By integrally forming the end plate 611 and the filter frame 612, it is beneficial to improve the structural strength of the filter support 61 and facilitate the manufacture of the filter support 61.

[0076] In some embodiments, the first end of the filter support 61 extends in the direction towards the guide ring 3 and is inclined along the direction close to the first cover plate 41. By arranging the filter support 61 obliquely, it is possible to prevent the air flow that has not been filtered by the filter 62 from flowing towards the fan inlet 21, facilitating the filtering of the air flow by the filter 62 while reducing the flow resistance of the air flow.

[0077] Specifically, Figure 3 illustrates the flow direction of the air flow in the fresh air mode. Since, in the flow direction of the air flow, the filter 62 is located upstream of the fan inlet 21, by extending the filter support 61 in the direction from top to bottom and arranging it obliquely backward, it is convenient for the filter 62 to filter the air flow while reducing the air flow resistance.

[0078] In some embodiments, as Figure 3 shown, the fan inlet 21 and the maintenance opening 11 are arranged opposite to each other in the first direction, the inclination angle of the filter support 61 relative to the first direction is α, and 20° ≤ α ≤ 70°.

[0079] In this embodiment, by limiting the angle between the filter support 61 and the first direction, on the one hand, it is possible to prevent the angle from being too large, which may increase the air flow resistance and reduce the air volume, and on the other hand, it is possible to prevent the angle from being too small, so that the exposed part of the filter support 61 is not within the maintenance area, increasing the difficulty of replacing the filter assembly 6, and realizing a large air volume while reducing the difficulty of replacing the filter 62.

[0080] It can be understood that the fresh air module is installed in the ceiling. The first part of the maintenance opening 11 is located in the ceiling, and the second part of the maintenance opening 11 is located in the maintenance area. By limiting the angle between the filter screen support 61 and the first direction, while avoiding excessive attenuation of the air volume, it is ensured that the end plate 611 of the filter screen support 61 is arranged in the maintenance area. That is to say, on the basis of ensuring that the filter screen support 61 can be taken out and installed from the second part of the maintenance opening 11, the air volume is increased as much as possible to achieve a large fresh air volume.

[0081] For example, the value of α is 20°, 30°, 40°, 50°, 60°, 70°.

[0082] In some embodiments, the fixing frame 5 includes a first fixing plate 51 and a second fixing plate 52. The first fixing plate 51 and the second fixing plate 52 are arranged at intervals. The filter screen assembly 6 is located between the first fixing plate 51 and the second fixing plate 52. At least one of the first fixing plate 51 and the second fixing plate 52 is detachably engaged with the filter screen assembly 6.

[0083] In this embodiment, the filter screen assembly 6 is arranged between the first fixing plate 51 and the second fixing plate 52. By detachably engaging the fixing plate with the filter screen assembly 6, it is convenient to assemble the filter screen assembly 6 with the fixing frame 5 and at the same time improves the convenience of taking out and installing the filter screen assembly 6 from the housing 1.

[0084] Specifically, as Figure 4 shown, the first fixing plate 51 and the second fixing plate 52 are arranged at intervals in the left-right direction. The left end of the filter screen assembly 6 is detachably engaged with the first fixing plate 51, and the right end of the filter screen assembly 6 is detachably engaged with the second fixing plate 52. Through the arrangement of the first fixing plate 51 and the second fixing plate 52, the stability and reliability of the engagement between the filter screen assembly 6 and the fixing frame 5 are improved.

[0085] In some embodiments, the fixing frame 5 is provided with a first clamping portion 53, and the filter screen assembly 6 is provided with a second clamping portion 63. One of the first clamping portion 53 and the second clamping portion 63 is a concave portion, and the other of the first clamping portion 53 and the second clamping portion 63 is a convex portion. The convex portion and the concave portion are detachably engaged.

[0086] In this embodiment, by providing the first clamping portion 53 on the fixing frame 5 and the second clamping portion 63 on the filter screen assembly 6, through the clamping and detachment of the first clamping portion 53 and the second clamping portion 63, the clamping and detachment between the fixing frame 5 and the filter screen assembly 6 are realized, and the operation is simple and convenient.

[0087] Specifically, as Figure 4As shown, a first clamping portion 53 is provided on one side of the fixing bracket 5 facing the filter screen frame 612, and a second clamping portion 63 is provided on one side of the filter screen frame 612 facing the corresponding fixing plate. That is to say, the first clamping portion 53 is provided on the right side of the first fixing plate 51 and the left side of the second fixing plate 52, and the second clamping portion 63 is provided on the left side and the right side of the filter screen frame 612.

[0088] Optionally, the first clamping portion 53 is a protrusion, and the second clamping portion 63 is a recess.

[0089] Optionally, slots are provided on both sides of the recess, and the slots communicate with the recess. The filter screen frame 612 includes a spring buckle, which has an end face and two side faces. The end face is part of the wall surface surrounding the recess, one side face is part of the wall surface surrounding one slot, and the other side face is part of the wall surface surrounding the other slot. When the recess engages with the protrusion, the spring buckle undergoes elastic deformation under the extrusion of the protrusion and is buckled on the protrusion. When the recess disengages from the protrusion, the spring buckle undergoes elastic deformation and disengages from the protrusion.

[0090] In some embodiments, the fixing bracket 5 is provided with a first guiding portion 54, the first guiding portion 54 is arranged at an interval from the first clamping portion 53, the filter screen assembly 6 is provided with a second guiding portion 64, the second guiding portion 64 is arranged at an interval from the second clamping portion 63, and the first guiding portion 54 and the second guiding portion 64 are movably matched relative to each other to guide the filter screen assembly 6 when removing and installing the filter screen assembly 6.

[0091] In this embodiment, the first guiding portion 54 is provided on the fixing bracket 5, and the second guiding portion 64 is provided on the filter screen assembly 6. The second guiding portion 64 moves along the extending direction of the first guiding portion 54 to guide the moving direction of the filter screen assembly 6, thereby improving the replacement efficiency of the filter screen assembly 6.

[0092] Specifically, as Figure 4 shown, the first guiding portion 54 is provided on the right side of the first fixing plate 51 and the left side of the second fixing plate 52, and the second guiding portion 64 is provided on the left side and the right side of the filter screen frame 612.

[0093] Optionally, when the filter screen bracket 61 is arranged obliquely, the first guiding portion 54 and the second guiding portion 64 are also arranged obliquely, and the inclination angles are the same.

[0094] In some embodiments, as Figure 4 shown, one of the first guiding portion 54 and the second guiding portion 64 is a convex column, and the other of the first guiding portion 54 and the second guiding portion 64 is a groove. When the filter screen assembly 6 engages with the fixing bracket 5, the convex column is fitted in the groove.

[0095] In this embodiment, through the cooperation of the convex posts and the grooves, on the one hand, the filter screen assembly 6 can be guided when the filter screen assembly 6 is taken out and installed, and on the other hand, the filter screen assembly 6 can be limited to improve the installation accuracy of the filter screen assembly 6.

[0096] Optionally, the first guiding portion 54 is a groove, and the second guiding portion 64 is a convex post.

[0097] In some embodiments, as Figure 4 shown, the fixing frame 5 is provided with a convex rib 55. The convex rib 55 is arranged at an interval from the first clamping portion 53 and is located on the side of the first clamping portion 53 away from the first guiding portion 54. The convex rib 55 abuts against the filter screen assembly 6.

[0098] In this embodiment, through the arrangement of the convex rib 55, the contact area between the filter screen assembly 6 and the fixing frame 5 is reduced, thereby reducing the resistance when the filter screen assembly 6 moves relative to the fixing frame 5, making the process of taking out and installing the filter screen assembly 6 from the fixing frame 5 smoother and improving the replacement efficiency.

[0099] Optionally, the extending direction of the convex rib 55 is the same as the extending direction of the first guiding portion 54, and the first clamping portion 53 is located between the convex rib 55 and the first guiding portion 54.

[0100] In some embodiments, as Figure 4 shown, the fixing frame 5 is provided with a limiting member 56. The limiting member 56 is located on the side of the first clamping portion 53 away from the first guiding portion 54, and the limiting member 56 is arranged at an interval from the filter screen assembly 6.

[0101] In this embodiment, by providing the limiting member 56 on the side of the first clamping portion 53 away from the first guiding portion 54 and arranging the limiting member 56 at an interval from the filter screen assembly 6, the moving range of the filter screen assembly 6 can be limited when the second guiding portion 64 of the filter screen assembly 6 is not assembled with the first guiding portion 54 of the fixing frame 5, thereby improving the efficiency of taking out and installing the filter screen assembly 6 from the fixing frame 5.

[0102] Specifically, the extending direction of the limiting member 56 is the same as the extending direction of the first guiding portion 54. The first clamping portion 53 is located between the first guiding portion 54 and the limiting member 56, and the convex rib 55 is located between the first clamping portion 53 and the limiting member 56.

[0103] In some embodiments, the first cover plate 41 and the fixing frame 5 are integrally formed. Thus, it is beneficial to improve the structural strength of the first cover plate 41 and the fixing frame 5 and facilitate the manufacture of the first cover plate 41 and the fixing frame 5.

[0104] In some embodiments, as Figures 1 - 3As shown, the fresh air module further includes a second cover plate 42, which is detachably disposed on the housing 1 and covers a part of the second part of the maintenance opening 11, so that the filter assembly 6 can be taken out from and inserted into the housing 1 through the part of the maintenance opening 11 located between the first cover plate 41 and the second cover plate 42.

[0105] In this embodiment, a part of the second part of the maintenance opening 11 is covered by the second cover plate 42, and another part of the second part of the maintenance opening 11 is covered by the filter assembly 6, so that the filter assembly 6 can be taken out from and inserted into the housing 1 between the first cover plate 41 and the second cover plate 42, realizing the replacement of the filter assembly 6 without removing the first cover plate 41 and the second cover plate 42.

[0106] Specifically, the second cover plate 42 is located behind the first cover plate 41 and within the maintenance area, facilitating the entry of indoor air into the housing 1 through the second cover plate 42 when the fresh air module is in the exhaust mode.

[0107] When performing maintenance on the blower 2 of the fresh air module, first take out the filter assembly 6, then remove the first cover plate 41 and the second cover plate 42, and finally separate the guide ring 3 from the blower 2, facilitating the maintenance of the blower 2.

[0108] In some embodiments, as Figure 3 shown, one end of the fixing frame 5 away from the first cover plate 41 abuts against the guide ring 3. By abutting one end of the fixing frame 5 away from the first cover plate 41 against the guide ring 3, on the one hand, it avoids the airflow passing through the gap between the fixing frame 5 and the guide ring 3, and on the other hand, it improves the stability of the fixing frame 5.

[0109] Optionally, the upper end of the fixing frame 5 abuts against the guide ring 3.

[0110] In some embodiments, as Figure 5 shown, the fresh air module further includes a rectifying member 7. The guide ring 3 has a guide opening 31, and the rectifying member 7 is disposed in the guide opening 31 and completely covers the guide opening 31. The rectifying member 7 includes a first grid 72 and a second grid 73 formed by rib strips 71. The first grid 72 includes a plurality of first through holes 721, and the second grid 73 includes a plurality of second through holes 731. The flow area of the first through holes 721 is larger than the flow area of the second through holes 731.

[0111] In this embodiment, by providing a flow rectifying member 7 at the diversion opening 31, the air flow passing through the diversion opening 31 is rectified by means of a plurality of first through holes 721 of the first grid 72 and a plurality of second through holes 731 of the second grid 73. By setting the flow area of the first through holes 721 to be larger than that of the second through holes 731, the first grid 72 can reduce the attenuation of the air volume while rectifying the air flow. The second grid 73 can better rectify the air flow with high turbulence, ensuring no obvious attenuation of the air volume while improving the rectifying effect and reducing the air flow noise, thereby enhancing the user experience.

[0112] The flow rectifying member 7 completely covers the diversion opening 31, ensuring that the flow rectifying member 7 can effectively divert and rectify the air flow passing through the diversion opening 31, reducing the turbulence phenomenon and improving the uniformity of the air flow.

[0113] In this embodiment, the first through holes 721 and the second through holes 731 with different flow areas are provided. The first through holes 721 with larger flow areas are used to rectify the air flow with low turbulence, and the second through holes 731 with smaller flow areas are used to rectify the air flow with high turbulence, ensuring the passing of a large air volume while improving the rectifying effect, effectively eliminating abnormal air flow sounds and reducing the total noise value, and enhancing the user experience.

[0114] In some embodiments, as Figure 5 shown, the rib 71 includes a plurality of first ribs 711, a plurality of second ribs 712 and a partition rib 713. The plurality of first ribs 711 are connected to each other to form a plurality of first through holes 721, the plurality of second ribs 712 are connected to each other to form a plurality of second through holes 731, and the partition rib 713 is arranged between the first grid 72 and the second grid 73.

[0115] In this embodiment, through the arrangement of connecting the plurality of first ribs 711 to each other, connecting the plurality of second ribs 712 to each other, and connecting the partition rib 713 to the first ribs 711 and the second ribs 712, on the basis of ensuring that the flow rectifying member 7 has sufficient structural strength, the arrangement density of the first through holes 721 and the second through holes 731 can be increased, and the rectifying effect can be improved.

[0116] Part of the first ribs 711 closest to the inner wall surface of the diversion opening 31 among the plurality of first ribs 711 are connected to the inner wall surface of the diversion opening 31 to enclose a part of the first through hole 721, and part of the second ribs 712 closest to the inner wall surface of the diversion opening 31 among the plurality of second ribs 712 are connected to the inner wall surface of the diversion opening 31 to enclose a part of the second through hole 731, realizing the connection between the flow rectifying member 7 and the diversion ring 3 while further increasing the arrangement density of the through holes 6112.
