Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and more specifically, to a fresh air module and an air conditioning device. Background Technology

[0002] As users have increasingly higher requirements for their living environment, their focus has shifted from regulating temperature and humidity to pursuing higher air quality. This has led to the development of air purifiers and air conditioning devices with fresh air modules. Fresh air modules have a filtration function, and the filters need to be replaced regularly to ensure effective filtration.

[0003] In related technologies, the filter support is installed on the flow guide ring. When replacing the filter, the inspection cover needs to be removed and the filter needs to be inserted into the housing to replace it, which is quite difficult. Summary of the Invention

[0004] This disclosure aims to at least partially address one of the technical problems in the related art. To this end, embodiments of this disclosure propose a fresh air module that reduces the difficulty of filter replacement and is simple and convenient to operate.

[0005] This disclosure also proposes an air conditioning device.

[0006] The fresh air module of this disclosure includes: a housing with an access port; a fan disposed within the housing and having an inlet opposite to the access port; a guide ring disposed within the housing and located at the fan inlet; a first cover plate detachably disposed within the housing to cover a first portion of the access port; a mounting bracket located within the housing and disposed on the first cover plate; and a filter assembly disposed within the housing for filtering air entering the fan inlet, the filter assembly being detachably engaged with the mounting bracket, a first end of the filter assembly adjacent to the guide ring, and a second end of the filter assembly located at a second portion of the access port.

[0007] The fresh air module of this embodiment has a first cover plate in the first part of the access port, and a fixing bracket is provided on the first cover plate. By placing the second end of the filter assembly at the second part of the access port, the filter assembly is detachably connected to the fixing bracket, so that the filter assembly can be taken out from the housing and put into the housing through the second part of the access port. The filter assembly can be replaced without removing the first cover plate, which reduces the difficulty of replacing the filter assembly. Moreover, when replacing the filter assembly, it is only necessary to pull the filter assembly to detach it from the fixing bracket, which is simple and convenient.

[0008] In some embodiments, the filter assembly includes a filter support and a filter, the filter being disposed on the filter support, the filter support being detachably engaged with the fixing frame, a first end of the filter support being adjacent to the flow guide ring, and a second end of the filter support being disposed within a second portion of the access port.

[0009] In this embodiment, the filter screen is placed on the filter screen support, with the first end of the filter screen support adjacent to the guide ring and the second section of the filter screen support located in the second part of the inspection port. The filter screen support and the fixing frame can be detachably connected, making it easy to remove and install the filter screen support from the housing through the second part of the inspection port. This allows the filter screen to be replaced without removing the first cover plate, reducing the difficulty of replacing the filter screen.

[0010] In some embodiments, the filter support includes an end plate and a filter frame, the filter frame being detachably engaged with the fixing frame, the filter being disposed on the filter frame, and the end plate being disposed at one end of the filter frame and located within the second portion of the access port.

[0011] In this embodiment, the filter screen frame is disposed inside the housing and detachably connected to the fixing frame. The end plate is connected to the filter screen frame and is located in the second part of the inspection port, so that the end of the end plate away from the filter screen frame is exposed. This makes it easy to detach or connect the filter screen frame to the fixing frame by operating the exposed part of the end plate, thereby realizing the replacement of the filter screen.

[0012] In some embodiments, at least a portion of the end plate presses against the mounting bracket. By pressing at least a portion of the end plate against the mounting bracket, it is easier to determine whether the filter frame and the mounting bracket are properly installed, and it also helps to improve the connection stability between the mounting bracket and the filter assembly.

[0013] In some embodiments, the filter frame is provided with clips for holding the filter. The clips facilitate holding the filter on the filter frame, improving filter replacement efficiency.

[0014] In some embodiments, the end plate is provided with a handle for removing and inserting the filter assembly into the housing. The handle facilitates operation of the end plate, thereby facilitating the removal and insertion of the filter assembly into the housing.

[0015] In some embodiments, the end plate is provided with a through hole for a fastener to pass through, thereby detachably connecting 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 to the housing, thereby achieving a 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. Integrating the end plate and the filter frame into one piece improves the structural strength of the filter support and facilitates its manufacturing.

[0017] In some embodiments, the first end of the filter support extends toward the guide ring and is inclined in a direction close to the first cover plate. By arranging the filter support at an incline, the filter can effectively filter the airflow while reducing the flow resistance of the airflow.

[0018] In some embodiments, the fan inlet and the inspection port are arranged opposite to each other in a first direction, and the filter support is tilted at an angle α relative to the first direction, with 20°≤α≤70°.

[0019] In this embodiment, by limiting the angle between the filter support and the first direction, on the one hand, it avoids that the angle is too large, which would increase airflow resistance and reduce air volume; on the other hand, it avoids that the angle is too small, which would cause the exposed part of the filter support to be outside the maintenance area, increasing the difficulty of replacing the filter assembly. This achieves a large air volume while reducing the difficulty of filter replacement.

[0020] In some embodiments, the mounting bracket includes a first mounting plate and a second mounting plate, the first mounting plate and the second mounting plate being arranged at a distance from each other, the filter assembly being located between the first mounting plate and the second mounting plate, and at least one of the first mounting plate and the second mounting plate being detachably engaged with the filter assembly.

[0021] In this embodiment, the filter assembly is placed between the first fixing plate and the second fixing plate. The fixing plate and the filter assembly can be detachably connected, which facilitates the assembly of the filter assembly with the fixing frame and improves the convenience of removing and installing the filter assembly from the housing.

[0022] In some embodiments, the fixing frame is provided with a first snap-fit ​​portion, the filter assembly is provided with a second snap-fit ​​portion, one of the first snap-fit ​​portion and the second snap-fit ​​portion is a recess, and the other of the first snap-fit ​​portion and the second snap-fit ​​portion is a convex portion, wherein the convex portion and the recess are detachably engaged.

[0023] In this embodiment, a first snap-fit ​​part is provided on the fixed frame, and a second snap-fit ​​part is provided on the filter assembly. The snap-fit ​​and detachment of the fixed frame and the filter assembly are realized through the snap-fit ​​and detachment of the first snap-fit ​​part and the second snap-fit ​​part, which is simple and convenient to operate.

[0024] In some embodiments, the fixing frame is provided with a first guide portion, which is spaced apart from the first snap-fit ​​portion. The filter assembly is provided with a second guide portion, which is spaced apart from the second snap-fit ​​portion. The first guide portion and the second guide portion are movable and cooperate with each other to guide the filter assembly when it is taken out and put in.

[0025] In this embodiment, a first guide part is provided on the fixed frame, and a second guide part is provided on the filter assembly. The second guide part moves along the extension direction of the first guide part to guide the movement direction of the filter assembly, thereby improving the replacement efficiency of the filter assembly.

[0026] In some embodiments, one of the first guide portion and the second guide portion is a protrusion, and the other of the first guide portion and the second guide portion is a groove, wherein the protrusion engages with the groove when the filter assembly is engaged with the fixing frame.

[0027] In this embodiment, the cooperation between the protrusion and the groove can guide the filter assembly when it is taken out and put in, and can also limit the filter assembly, thereby improving the installation accuracy of the filter assembly.

[0028] In some embodiments, the fixing frame is provided with a rib, the rib is arranged at a distance from the first snap-fit ​​portion and is located on the side of the first snap-fit ​​portion away from the first guide portion, and the rib abuts against the filter assembly.

[0029] In this embodiment, the contact area between the filter assembly and the fixing frame is reduced by setting the ribs, thereby reducing the resistance when the filter assembly moves relative to the fixing frame, making the process of taking the filter assembly out of the fixing frame and putting it in smoother and improving the replacement efficiency.

[0030] In some embodiments, the fixing frame is provided with a limiting member, which is located on the side of the first snap-fit ​​portion away from the first guide portion, and the limiting member is arranged at a distance from the filter assembly.

[0031] In this embodiment, a limiting member is provided on the side of the first latching portion away from the first guide portion, and the limiting member is arranged at a distance from the filter assembly, so as to limit the movement range of the filter assembly when the second guide portion of the filter assembly is not assembled with the first guide portion of the fixing frame, thereby improving the efficiency of taking the filter assembly out of and putting it into the fixing frame.

[0032] In some embodiments, the first cover plate and the fixing frame are integrally formed. This improves the structural strength of the first cover plate and the fixing frame while facilitating their manufacture.

[0033] In some embodiments, the fresh air module further includes a second cover plate detachably disposed on the housing and covering a portion of a second part of the access port, so that the filter assembly can be removed from the portion of the access port located between the first cover plate and the second cover plate and inserted into the housing.

[0034] In this embodiment, a second cover plate covers a portion of the second part of the access port, and a filter assembly covers the other part of the second part of the access port, so that the filter assembly can be taken out and installed between the first cover plate and the second cover plate, thereby enabling the filter assembly to be replaced without removing the first cover plate and the second cover plate.

[0035] In some embodiments, the end of the mounting bracket away from the first cover plate abuts against the guide ring. By abutting the end of the mounting bracket away from the first cover plate against the guide ring, airflow is prevented from passing through the gap between the mounting bracket and the guide ring, and the stability of the mounting bracket is improved.

[0036] In some embodiments, the fresh air module further includes a rectifier, the guide ring has a guide port, the rectifier is disposed at the guide port and completely covers the guide port, the rectifier includes a first grille and a second grille formed by ribs, the first grille includes a plurality of first through holes, the second grille 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] This embodiment uses a rectifier at the airflow guide to rectify the airflow passing through the airflow guide by using multiple first through holes of the first grille and multiple second through holes of the second grille. By setting the flow area of ​​the first through holes to be larger than that of the second through holes, the first grille can reduce airflow attenuation while rectifying the airflow, and the second grille can better rectify the airflow with high turbulence. This ensures that the airflow does not decrease significantly while improving the rectification effect, reducing airflow noise, and thus improving the user experience.

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

[0039] In this embodiment, by connecting multiple first ribs, connecting multiple second ribs, and using a separator rib to connect the first and second ribs, the arrangement density of the first and second through holes can be increased while ensuring that the rectifier has sufficient structural strength, thereby improving the rectification effect.

[0040] The air conditioning device of this disclosure includes the fresh air module described in the above embodiments.

[0041] The air conditioning device of this disclosure improves the performance of the air conditioning device by including the fresh air module of the above embodiment. Attached Figure Description

[0057] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0058] The following is in conjunction with the appendix Figures 1 to 5 The fresh air module of the present disclosure will be described in detail.

[0059] The fresh air module of this embodiment includes a housing 1, a fan 2, a guide ring 3, a first cover plate 41, a mounting bracket 5, and a filter assembly 6. The housing 1 has an access port 11. The fan 2 is disposed within the housing 1 and has a fan inlet 21 opposite to the access port 11. The guide ring 3 is disposed within the housing 1 and located at the fan inlet 21. The first cover plate 41 is detachably disposed on the housing 1 to cover a first portion of the access port 11. The mounting bracket 5 is located within the housing 1 and disposed on the first cover plate 41. The filter assembly 6 is disposed within the housing 1 and is used to filter the air entering the fan inlet 21. The filter assembly 6 is detachably engaged with the mounting bracket 5, with a first end of the filter assembly 6 adjacent to the guide ring 3 and a second end of the filter assembly 6 located at a second portion of the access port 11.

[0060] The fresh air module of this embodiment has a first cover plate 41 provided in the first part of the access port 11, and a fixing bracket 5 provided on the first cover plate 41. By positioning the second end of the filter assembly 6 at the second part of the access port 11, the filter assembly 6 is detachably connected to the fixing bracket 5, so that the filter assembly 6 can be taken out from the housing 1 and installed into the housing 1 through the second part of the access port 11. The filter assembly 6 can be replaced without removing the first cover plate 41, which reduces the difficulty of replacing the filter assembly 6. Moreover, when replacing the filter assembly 6, it is only necessary to pull the filter assembly 6 to detach the filter assembly 6 from the fixing bracket 5, which is simple and convenient.

[0061] Specifically, such as Figures 1-4 As shown, the lower end of the housing 1 is provided with an inspection port 11. The fan inlet 21 is located at the lower end of the fan 2 and is arranged opposite to the inspection port 11 in the vertical direction. The guide ring 3 is located at the fan inlet 21 at the lower end of the fan 2. The first part and the second part of the inspection port 11 are arranged adjacent to each other in the front-back direction and are connected as one unit. The first cover plate 41 covers the first part of the inspection port 11, and the fixing bracket 5 is connected to the upper end of the first cover plate 41.

[0062] The filter assembly 6 can be detachably engaged with the mounting bracket 5. When the filter assembly 6 is engaged with the mounting 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 inspection port 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 detached from the mounting bracket 5, it is easy to remove the filter assembly 6 from the housing 1 through the second part of the inspection port 11 to replace the filter assembly 6.

[0063] In some embodiments, the filter assembly 6 includes a filter support 61 and a filter 62, the filter 62 being disposed on the filter support 61, the filter support 61 being detachably engaged with the fixing frame 5, the first end of the filter support 61 being adjacent to the guide ring 3, and the second end of the filter support 61 being disposed within the second portion of the access port 11.

[0064] In this embodiment, the filter screen 62 is placed on the filter screen bracket 61. The first end of the filter screen bracket 61 is adjacent to the guide ring 3, and the second section of the filter screen bracket 61 is located in the second part of the inspection port 11. By utilizing the filter screen bracket 61 and the fixing frame 5 to be detachably connected, it is convenient to remove and install the filter screen bracket 61 from the housing 1 through the second part of the inspection port 11. This allows the filter screen 62 to be replaced without removing the first cover plate 41, reducing the difficulty of replacing the filter screen 62.

[0065] Optionally, the filter screen 62 and the filter screen support 61 are detachably connected, making it easy to remove the filter screen support 61 from the housing 1 and replace the filter screen 62.

[0066] In some embodiments, the filter support 61 includes an end plate 611 and a filter frame 612. The filter frame 612 is detachably engaged with the fixing frame 5. The filter 62 is disposed on the filter frame 612. The end plate 611 is disposed at one end of the filter frame 612 and located within the second part of the access port 11.

[0067] In this embodiment, the filter frame 612 is disposed inside the housing 1 and detachably connected to the fixing frame 5. The end plate 611 is connected to the filter frame 612 and disposed in the second part of the inspection port 11, so that the end of the end plate 611 away from the filter frame 612 is exposed. This makes it easy to detach or connect the filter frame 612 to the fixing frame 5 by operating the exposed part of the end plate 611, thereby realizing the replacement of the filter 62.

[0068] Specifically, such as Figure 2 As shown, the end plate 611 is detachably connected to the housing 1 to cover the second part of the access port 11. The upper end of the end plate 611 is connected to the lower end of the filter frame 612. The lower end of the end plate 611 is exposed. By pulling the end plate 611 downward, the filter frame 612 can be separated from the fixing frame 5.

[0069] In some embodiments, at least a portion of the end plate 611 presses against the fixing frame 5. By pressing at least a portion of the end plate 611 against the fixing frame 5, it is easier to determine whether the filter frame 612 and the fixing frame 5 are installed in place, and it also helps to improve the connection stability between the fixing frame 5 and the filter assembly 6.

[0070] Specifically, such as Figure 3 As shown, the upper front end of the end plate 611 presses against the fixing frame 5 to achieve a sealed connection between the end plate 611 and the fixing frame 5, preventing airflow inside 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, such as Figure 4 As shown, the filter frame 612 is provided with a clip 6121 for holding the filter 62. The clip 6121 makes it easy to hold the filter 62 on the filter frame 612, thereby improving the filter 62 replacement efficiency.

[0072] In some embodiments, such as Figure 4 As shown, the end plate 611 is provided with a handle 6111 for removing and installing the filter assembly 6 into the housing 1. The handle 6111 facilitates operation of the end plate 611, thereby facilitating the removal and installation of the filter assembly 6 into the housing 1.

[0073] Optionally, the lower end face of the end plate 611 is provided with a recess to form a handle 6111.

[0074] In some embodiments, such as Figure 4 As shown, the end plate 611 is provided with a through hole 6112 for fasteners to pass through so as to detachably connect the end plate 611 to the housing 1. By providing a through hole 6112 on the end plate 611, it is convenient for fasteners to pass through the through hole 6112 and connect to the housing 1, thereby realizing a 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, the structural strength of the filter support 61 is improved, while the manufacturing of the filter support 61 is also facilitated.

[0076] In some embodiments, the first end of the filter support 61 extends toward the guide ring 3 and is inclined in the direction close to the first cover plate 41. By arranging the filter support 61 at an incline, unfiltered airflow is prevented from flowing toward the fan inlet 21, which facilitates the filter 62 in filtering the airflow while reducing the flow resistance of the airflow.

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

[0078] In some embodiments, such as Figure 3 As shown, the fan inlet 21 and the maintenance port 11 are arranged opposite each other in the first direction, and the filter support 61 is tilted at an angle α relative to the first direction, 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, the angle is too large, which increases airflow resistance and reduces air volume; on the other hand, the angle is too small, which would cause the exposed part of the filter support 61 to be outside the maintenance area, increasing the difficulty of replacing the filter assembly 6. This achieves a large air volume while reducing the difficulty of replacing the filter 62.

[0080] It is understandable that the fresh air module is installed in the ceiling, the first part of the inspection port 11 is located in the ceiling, and the second part of the inspection port 11 is located in the maintenance area. By limiting the angle between the filter support 61 and the first direction, the air volume is prevented from being too attenuated while ensuring that the end plate 611 of the filter support 61 is located in the maintenance area. In other words, the air volume is maximized as much as possible while ensuring that the filter support 61 can be taken out and installed from the second part of the inspection port 11 to achieve a large fresh air volume.

[0081] For example, α can take values ​​of 20°, 30°, 40°, 50°, 60°, and 70°.

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

[0083] In this embodiment, the filter assembly 6 is disposed between the first fixing plate 51 and the second fixing plate 52. The fixing plate and the filter assembly 6 can be detachably connected, which facilitates the assembly of the filter assembly 6 with the fixing frame 5 and improves the convenience of removing and installing the filter assembly 6 from the housing 1.

[0084] Specifically, such as Figure 4 As shown, the first fixing plate 51 and the second fixing plate 52 are arranged at intervals in the left and right directions. The left end of the filter assembly 6 is detachably connected to the first fixing plate 51, and the right end of the filter assembly 6 is detachably connected to the second fixing plate 52. The arrangement of the first fixing plate 51 and the second fixing plate 52 improves the stability and reliability of the filter assembly 6 when it is connected to the fixing frame 5.

[0085] In some embodiments, the mounting bracket 5 is provided with a first snap-fit ​​portion 53, and the filter assembly 6 is provided with a second snap-fit ​​portion 63. One of the first snap-fit ​​portion 53 and the second snap-fit ​​portion 63 is a recess, and the other of the first snap-fit ​​portion 53 and the second snap-fit ​​portion 63 is a convex portion. The convex portion and the recess are detachably engaged.

[0086] In this embodiment, a first snap-fit ​​part 53 is provided on the fixing frame 5, and a second snap-fit ​​part 63 is provided on the filter assembly 6. The snap-fit ​​and detachment of the fixing frame 5 and the filter assembly 6 are realized through the snap-fit ​​and detachment of the first snap-fit ​​part 53 and the second snap-fit ​​part 63, which is simple and convenient to operate.

[0087] Specifically, such as Figure 4As shown, the fixing frame 5 has a first snap-fit ​​part 53 on the side facing the filter frame 612, and the filter frame 612 has a second snap-fit ​​part 63 on the side facing the corresponding fixing plate. That is, the first snap-fit ​​part 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 snap-fit ​​part 63 is provided on the left side and the right side of the filter frame 612.

[0088] Optionally, the first latching portion 53 is a protrusion, and the second latching 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 frame 612 includes a spring clip, which has an end face and two side faces. The end face is part of the wall surrounding the recess, one side face is part of the wall surrounding one slot, and the other side face is part of the wall surrounding another slot. When the recess and the convex part are engaged, the spring clip undergoes elastic deformation under the compression of the convex part and engages with the convex part. When the recess and the convex part are disengaged, the spring clip undergoes elastic deformation and disengages from the convex part.

[0090] In some embodiments, the mounting bracket 5 is provided with a first guide portion 54, which is spaced apart from the first snap-fit ​​portion 53. The filter assembly 6 is provided with a second guide portion 64, which is spaced apart from the second snap-fit ​​portion 63. The first guide portion 54 and the second guide portion 64 can move and cooperate relative to each other to guide the filter assembly 6 when it is taken out and put in.

[0091] In this embodiment, a first guide part 54 is provided on the fixing frame 5, and a second guide part 64 is provided on the filter assembly 6. The second guide part 64 moves along the extension direction of the first guide part 54 to guide the movement direction of the filter assembly 6, thereby improving the replacement efficiency of the filter assembly 6.

[0092] Specifically, such as Figure 4 As shown, the first guide part 54 is located on the right side of the first fixing plate 51 and the left side of the second fixing plate 52, and the second guide part 64 is located on the left and right sides of the filter frame 612.

[0093] Optionally, when the filter support 61 is arranged at an angle, the first guide part 54 and the second guide part 64 are also arranged at an angle, and the angles of inclination are the same.

[0094] In some embodiments, such as Figure 4 As shown, one of the first guide portion 54 and the second guide portion 64 is a protrusion, and the other of the first guide portion 54 and the second guide portion 64 is a groove. When the filter assembly 6 is engaged with the fixing frame 5, the protrusion fits into the groove.

[0095] In this embodiment, the cooperation between the protrusion and the groove can guide the filter assembly 6 when it is taken out and put in, and can also limit the filter assembly 6, thereby improving the installation accuracy of the filter assembly 6.

[0096] Optionally, the first guide portion 54 is a groove, and the second guide portion 64 is a protrusion.

[0097] In some embodiments, such as Figure 4 As shown, the fixing frame 5 is provided with a protruding rib 55. The protruding rib 55 is arranged at intervals with the first snap-fit ​​part 53 and is located on the side of the first snap-fit ​​part 53 away from the first guide part 54. The protruding rib 55 abuts against the filter assembly 6.

[0098] In this embodiment, the contact area between the filter assembly 6 and the fixing frame 5 is reduced by the setting of the rib 55, thereby reducing the resistance when the filter assembly 6 moves relative to the fixing frame 5, making the process of taking the filter assembly 6 out of the fixing frame 5 and putting it in smoother and improving the replacement efficiency.

[0099] Optionally, the extension direction of the rib 55 is the same as the extension direction of the first guide portion 54, and the first snap-fit ​​portion 53 is located between the rib 55 and the first guide portion 54.

[0100] In some embodiments, such as Figure 4 As shown, the fixing frame 5 is provided with a limiting member 56, which is located on the side of the first snap-fit ​​portion 53 away from the first guide portion 54. The limiting member 56 is arranged at intervals with the filter assembly 6.

[0101] In this embodiment, a limiting member 56 is provided on the side of the first latching part 53 away from the first guide part 54, and the limiting member 56 is arranged at a distance from the filter assembly 6, so as to limit the movement range of the filter assembly 6 when the second guide part 64 of the filter assembly 6 is not assembled with the first guide part 54 of the fixing frame 5, thereby improving the efficiency of taking the filter assembly 6 out of the fixing frame 5 and putting it in.

[0102] Specifically, the extension direction of the limiting member 56 is the same as the extension direction of the first guide portion 54, the first engaging portion 53 is located between the first guide portion 54 and the limiting member 56, and the protruding rib 55 is located between the first engaging portion 53 and the limiting member 56.

[0103] In some embodiments, the first cover plate 41 and the fixing frame 5 are integrally formed. This improves the structural strength of the first cover plate 41 and the fixing frame 5 while facilitating their manufacture.

[0104] In some embodiments, such as Figures 1-3As shown, the fresh air module also includes a second cover plate 42, which is detachably disposed on the housing 1 and covers a portion of the second part of the access port 11 so that the filter assembly 6 can be removed from the portion of the access port 11 located between the first cover plate 41 and the second cover plate 42 and installed into the housing 1.

[0105] In this embodiment, a portion of the second part of the inspection port 11 is covered by the second cover plate 42, and the other part of the second part of the inspection port 11 is covered by the filter assembly 6, so that the filter assembly 6 can be taken out and installed between the first cover plate 41 and the second cover plate 42, thereby enabling 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 is located within the maintenance area, so that indoor air can enter the housing 1 from the second cover plate 42 when the fresh air module is in exhaust mode.

[0107] When overhauling the fan 2 of the fresh air module, first remove 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 fan 2 to facilitate the overhaul of the fan 2.

[0108] In some embodiments, such as Figure 3 As shown, the end of the fixing frame 5 furthest from the first cover plate 41 abuts against the guide ring 3. By abutting the end of the fixing frame 5 furthest from the first cover plate 41 against the guide ring 3, airflow is prevented from passing through the gap between the fixing frame 5 and the guide ring 3, and the stability of the fixing frame 5 is improved.

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

[0110] In some embodiments, such as Figure 5 As shown, the fresh air module also includes a rectifier 7. The guide ring 3 has a guide port 31. The rectifier 7 is disposed at the guide port 31 and completely covers the guide port 31. The rectifier 7 includes a first grille 72 and a second grille 73 formed by ribs 71. The first grille 72 includes a plurality of first through holes 721, and the second grille 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 setting a rectifier 7 in the guide port 31, the airflow passing through the guide port 31 is rectified by using multiple first through holes 721 of the first grille 72 and multiple second through holes 731 of the second grille 73. By setting the flow area of ​​the first through hole 721 to be larger than that of the second through hole 731, the first grille 72 can reduce the airflow attenuation while rectifying the airflow, and the second grille 73 can better rectify the airflow with high turbulence, ensuring that the airflow does not decrease significantly while improving the rectification effect, reducing airflow noise, and thus improving the user experience.

[0112] The rectifier 7 completely covers the guide port 31, ensuring that the rectifier 7 can effectively guide and rectify the airflow passing through the guide port 31, reduce turbulence, and improve the uniformity of the airflow.

[0113] In this embodiment, a first through-hole 721 and a second through-hole 731 with different flow areas are provided. The first through-hole 721 with a larger flow area is used to rectify the airflow with low turbulence, while the second through-hole 731 with a smaller flow area is used to rectify the airflow with high turbulence. This ensures that a large volume of airflow passes through while improving the rectification effect, effectively eliminating abnormal airflow noise and reducing the total noise level, thereby improving the user experience.

[0114] In some embodiments, such as Figure 5 As 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 interconnected to form a plurality of first through holes 721, the plurality of second ribs 712 are interconnected to form a plurality of second through holes 731, and the partition rib 713 is disposed between the first grid 72 and the second grid 73.

[0115] In this embodiment, by connecting multiple first ribs 711 to each other, connecting multiple second ribs 712 to each other, and using a separating rib 713 to connect the first ribs 711 and the second ribs 712, the arrangement density of the first through holes 721 and the second through holes 731 can be increased to improve the rectification effect while ensuring that the rectifier 7 has sufficient structural strength.

[0116] The portion of the first rib 711 closest to the inner wall of the guide port 31 is connected to the inner wall of the guide port 31 to form part of the first through hole 721. The portion of the second rib 712 closest to the inner wall of the guide port 31 is connected to the inner wall of the guide port 31 to form part of the second through hole 731. This achieves the connection between the rectifier 7 and the guide ring 3 while further increasing the arrangement density of the through holes 6112.
