[0048] With consumers becoming increasingly health-conscious, air conditioners with fresh air intake functions have become a trend in high-end products. However, in these technologies, air conditioners with fresh air intake typically lack a primary filter on the fresh air inlet side. After prolonged use, hair and other foreign objects easily accumulate in the air ducts, making them difficult to clean. Furthermore, these foreign objects adhere to HEPA filters and other functional modules through the air ducts, reducing their lifespan.
[0049] Based on the above findings, this invention proposes an air conditioner 100 with a fresh air function (here, the fresh air function can be either introducing fresh air from the outside or processing indoor air to obtain fresh air), and a second filter component 34 with preliminary filtration is provided on the air inlet side, which can filter out foreign objects such as hair. The first filter component 33 then performs dust removal, sterilization and other functions to keep the inside of the air duct clean, and the first filter component 33 has a long service life.
[0050] An air conditioner 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.
[0051] Reference Figures 1-5 As shown, the air conditioner 100 according to an embodiment of the present invention may include: a housing 10, an air duct assembly 20, and an air handling assembly 30.
[0052] Specifically, such as Figures 1-4 As shown, the housing 10 can define a first air duct space 11 and a second air duct space 12. The first air duct space 11 and the second air duct space 12 can be connected to each other so that gas can flow between the first air duct space 11 and the second air duct space 12, which is beneficial to increasing the air intake or exhaust area; or, the first air duct space 11 and the second air duct space 12 can be isolated from each other.
[0053] like Figures 1-4 As shown, the housing 10 may also be provided with a first air inlet 111, a first air outlet 112, a second air inlet 121, and a second air outlet 122. The first air inlet 111 and the first air outlet 112 correspond to the first air duct space 11, allowing gas flowing into the housing 10 from the first air inlet 111 to be processed by components within the first air duct space 11 before flowing out from the first air outlet 112. The second air inlet 121 and the second air outlet 122 correspond to the second air duct space 12, allowing gas flowing into the housing 10 from the second air inlet 121 to be processed by components within the second air duct space 12 before flowing out from the second air outlet 122.
[0054] In such Figure 4 In the specific embodiment shown, the housing 10 includes a rear casing 17, a top cover 14, a base 19, and a front casing. The rear casing 17 can be composed of one or more pieces, and the front casing can also be composed of one or more pieces. The front casing includes an upper panel 15 and a lower panel 16 as an example. The lower end of the rear casing 17 is connected to the rear of the base 19, the lower end of the lower panel 16 is connected to the front of the base 19, the upper panel 15 is located above the lower panel 16, and both the upper panel 15 and the lower panel 16 are connected to the side edges of the rear casing 17. The top cover 14 is connected to the upper panel 15 and the upper end of the rear casing 17, thus forming the housing 10 of the air conditioner 100.
[0055] The space between the upper part of the rear housing 17 and the upper panel 15 forms a first air duct space 11. The upper part of the rear housing 17 has a first air inlet 111, and the left and right sides of the upper panel 15 each have a first air outlet 112. An air outlet door can be provided at the first air outlet 112 to open or close it. The space between the lower part of the rear housing 17 and the lower panel 16 forms a second air duct space 12. A second air outlet 122 can be located on either the rear housing 17 or the lower panel 16. Figure 4In the example shown, the lower part of the rear housing 17 is provided with a second air inlet 121 and a second air outlet 122, and the second air outlet 122 is located above the second air inlet 121. There are two second air outlets 122, which are respectively located on the left and right sides of the lower part of the rear housing 17.
[0056] In some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the second air inlet 121 may include a fresh air inlet 124, which can introduce external fresh air into the second air duct space 12, and after being processed by the components in the second air duct space 12, it is discharged into the room through the second air outlet 122, thereby realizing the function of providing fresh air to the room.
[0057] In some embodiments of the present invention, such as Figure 7 and Figure 8 As shown, the second air inlet 121 may include an internal circulation air inlet 125. Indoor air can enter the second air duct space 12 through the internal circulation air inlet 125, and after being processed by the components in the second air duct space 12, it will return to the room through the second air outlet 122, so that the indoor air can be purified.
[0058] In some embodiments that include both a fresh air inlet 124 and an internal circulation air inlet 125, a switch valve may be provided at the fresh air inlet 124 and the internal circulation air inlet 125 respectively. The on / off state of the fresh air inlet 124 and the internal circulation air inlet 125 can be controlled by the switch valve, thereby realizing the fresh air function and the indoor air purification function to be performed separately or simultaneously.
[0059] In such Figures 3-8 In the specific embodiment shown, the second air inlet 121 includes two internal circulation air inlets 125 and one fresh air inlet 124. The two internal circulation air inlets 125 are respectively located on the left and right sides of the lower part of the rear housing 17 to facilitate indoor air circulation. The fresh air inlet 124 is located between the two internal circulation air inlets 125 to facilitate communication with the outside and to make the air conditioner 100 look aesthetically pleasing.
[0060] According to some embodiments of the present invention, such as Figure 4 As shown, the air duct assembly 20 can be disposed in the first air duct space 11, and the operation of the air duct assembly 20 can drive gas from the first air inlet 111 to the first air outlet 112 to improve cooling or heating efficiency. In some embodiments of the present invention, the air conditioner 100 further includes a heat exchanger 18, which is disposed in the first air duct space 11. Driven by the air duct assembly 20, gas flows through the heat exchanger 18 to exchange heat with the heat exchanger 18, thereby realizing the cooling or heating function.
[0061] Reference Figures 4-8As shown, the air handling assembly 30 can be disposed in the second air duct space 12, and the air handling assembly 30 includes a housing 31, a fan 32, a first filter assembly 33, and a second filter assembly 34. The housing 31 defines a gas flow channel 311, which connects a second air inlet 121 and a second air outlet 122. The fan 32 is disposed within the gas flow channel 311 to drive gas flow from the second air inlet 121 to the second air outlet 122. Both the first filter assembly 33 and the second filter assembly 34 are installed within the gas flow channel 311, and in the gas flow direction, the second filter assembly 34 is located on the air inlet side of the first filter assembly 33; in other words, the gas first flows through the second filter assembly 34 and then through the first filter assembly 33.
[0062] Therefore, by using the first filter component 33 and the second filter component 34 to perform dual treatment of the gas, a better purification effect can be achieved.
[0063] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, in the gas flow direction, the second filter component 34 can be located on the air inlet side of the impeller 32 so that the gas flows through the second filter component 34 before flowing through the impeller 32, avoiding foreign objects such as hair and dust in the gas from adhering to or getting tangled on the impeller 32 and affecting the normal rotation of the impeller 32, and also keeping the inside of the gas flow channel 311 clean.
[0064] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, in the gas flow direction, the first filter assembly 33 can be located on the air outlet side of the impeller 32 or on the air inlet side of the impeller 32, that is, between the impeller 32 and the second filter assembly 34, which is within the protection scope of this invention. Figure 6 In the example shown, the first filter assembly 33 is located on the air outlet side of the impeller 32, that is, the impeller 32 is located between the first filter assembly 33 and the second filter assembly 34, so that the impeller 32 can provide efficient gas driving force at both the first filter assembly 33 and the second filter assembly 34, thereby improving the filtration efficiency at both locations.
[0065] In some embodiments of the present invention, such as Figures 3-8As shown, the housing 10 may also be provided with a disassembly port 123, which corresponds to the second air duct space 12, so that the second filter assembly 34 can be disassembled through the disassembly port 123. During the operation of the air handling unit 30, the second filter assembly 34 pre-treats the gas, filtering out most of the foreign objects such as hair, preventing foreign objects from adhering to the first filter assembly 33, and improving the service life of the first filter assembly 33. Furthermore, the second filter assembly 34 can be disassembled and installed through the disassembly port 123, allowing users to remove the second filter assembly 34 for cleaning and replacement. During disassembly and installation, it is not necessary to disassemble the housing 10 of the air conditioner 100; the operation can be performed directly through the disassembly port 123. No professional personnel are required; users can disassemble and clean the second filter assembly 34 themselves, greatly improving the convenience of operation and user experience.
[0066] In some specific embodiments, the second filter assembly 34 may include a pre-filter, and the first filter assembly 33 may include a HEPA filter. The pre-filter is mainly used to filter dust particles larger than 5μm, such as hair, to prevent foreign objects from adhering to the HEPA filter and reducing its lifespan. Furthermore, the pre-filter can be washed and reused, reducing operating costs. The HEPA filter can further process the pre-filtered gas, removing dust and bacteria, achieving a removal efficiency of over 99.97% for particles larger than 0.3μm, effectively removing pollutants such as smoke, dust, and bacteria. The combination of the pre-filter and the HEPA filter achieves excellent air purification. Of course, the filtration structures of the first filter assembly 33 and the second filter assembly 34 include, but are not limited to, a pre-filter and a HEPA filter.
[0067] In some embodiments where the second air inlet 121 includes an internal circulation air inlet 125 and a fresh air inlet 124, such as Figure 5 and Figure 7 As shown, the disassembly port 123 can be located near the internal circulation air inlet 125, for example, on the lower left or right side of the rear housing 17, so that the user can disassemble the second filter component 34 and better shield the connecting pipe and other structures at the fresh air inlet 124.
[0068] According to an embodiment of the present invention, the air conditioner 100 has cooling and heating functions and air handling functions by installing an air duct assembly 20 and an air handling assembly 30 inside the housing 10. The air is initially filtered by the second filter assembly 34 and then filtered by the first filter assembly 33, which improves the air handling effect and the service life of the first filter assembly 33. The second filter assembly 34 can be disassembled and installed through the disassembly port 123 on the housing 10, which is convenient for replacement and cleaning. The operation is simple and does not require disassembling the housing 10, thus improving the user experience.
[0069] According to some embodiments of the present invention, such as Figures 7-12 As shown, the inner wall of the gas flow channel 311 may be provided with a guide groove 312. The insertion port 313 of the guide groove 312 is arranged opposite to the disassembly port 123 so that the second filter component 34 can be inserted into the guide groove 312 through the disassembly port 123 and the insertion port 313, and slide along the guide groove 312 under the guidance of the guide groove 312 to realize disassembly and installation. Disassembly is simple and convenient, and installation can ensure that the second filter component 34 is installed in place so as to fully purify the gas in the gas flow channel 311.
[0070] In some embodiments of the present invention, such as Figure 7 As shown, the gas in the area where the guide chute 312 is located flows from back to front. The guide chute 312 extends generally in the left and right direction so that the second filter assembly 34 can be slidably installed and removed in the left and right direction. After installation, the second filter assembly 34 extends generally in the left and right and up and down directions to form a larger filtration area and improve gas flow and filtration efficiency.
[0071] In some embodiments of the present invention, such as Figure 10 As shown, there can be two guide grooves 312. The two guide grooves 312 respectively cooperate with the two side edges of the second filter assembly 34 to guide it, so as to improve the overall movement consistency of the second filter assembly 34 and avoid deformation of the second filter assembly 34, which would affect the disassembly and assembly.
[0072] In the embodiments of the present invention, the location and specific structure of the guide groove 312 can be flexibly set according to the actual situation.
[0073] In some embodiments of the present invention, such as Figures 8-12 As shown, the housing 31 may include a volute 314 and an air inlet bracket 315, which define at least a portion of the gas flow channel 311. The impeller 32 may be disposed within the volute 314 to drive gas flow within the volute 314, thereby driving gas flow throughout the entire gas flow channel 311. The air inlet bracket 315 may be disposed on the side of the volute 314 near (in the gas flow direction) the second air inlet 121, and the air inlet bracket 315 is connected to the volute 314 to allow communication between their internal spaces. At least one of the volute 314 and the air inlet bracket 315 may define a guide groove 312 to limit the second filter assembly 34 to the air inlet side of the impeller 32, ensuring that gas is filtered by the second filter assembly 34 before flowing through the impeller 32, preventing entanglement in the impeller 32.
[0074] In some embodiments of the present invention, the volute 314 and the air inlet bracket 315 cooperate to define a guide groove 312. Specifically, as Figures 10-14As shown, the sidewall of the volute 314 and the sidewall of the air inlet bracket 315 are respectively provided with protrusions 316, and the protrusions 316 are located between the sidewall of the volute 314 and the sidewall of the air inlet bracket 315, so that the sidewall of the volute 314 and the sidewall of the air inlet bracket 315 can be spaced apart by a predetermined gap, thereby defining the guide groove 312. The protrusions 316 can be formed as the bottom wall of the guide groove 312, and the sidewall of the volute 314 and the sidewall of the air inlet bracket 315 can be formed as the sidewall of the guide groove 312. Compared with setting grooves on the volute 314 or the air inlet bracket 315 to form the guide groove 312, the guide groove 312 is defined by the cooperation of the volute 314 and the air inlet bracket 315, which makes the structure of the volute 314 and the air inlet bracket 315 simple and easy to form. The groove wall structure of the guide groove 312 has high strength, and the protrusion 316 can further improve the structural strength of the volute 314 and the air inlet bracket 315.
[0075] In such Figures 10-14 In the specific embodiment shown, the side wall of the volute 314 may be provided with two protrusions 316, referred to as the first protrusions 316. The two first protrusions 316 are respectively located on both sides of the gas flow channel 311. The side wall of the air inlet bracket 315 is also provided with two protrusions 316, referred to as the second protrusions 316. The two second protrusions 316 are arranged one-to-one with the two first protrusions 316, and the two first protrusions 316 are respectively located on the side closer to each other or the side farther away from each other, so that the adjacent first protrusions 316 and second protrusions 316 can support and cooperate with each other. This not only defines the guide groove 312 and improves the strength of the volute 314 and the air inlet bracket 315, but also limits the volute 314 and the air inlet bracket 315. It also helps to reduce or avoid gas leakage from the cooperation gap between the volute 314 and the air inlet bracket 315.
[0076] Of course, the protrusion 316 may also be provided only on the side wall of the volute 314, or only on the side wall of the air inlet bracket 315, as long as the protrusion 316 is located between the side wall of the volute 314 and the side wall of the air inlet bracket 315, so as to cooperate with the side wall of the volute 314 and the side wall of the air inlet bracket 315 to define the guide groove 312. In some embodiments of the present invention, the protrusion 316 may be a rib extending perpendicular to the gas flow direction.
[0077] According to some specific embodiments of the present invention, such as Figure 5 and Figure 6As shown, the housing 31 may further include a fresh air component 318 and an air outlet component 317. The impeller 32 is a single-flow impeller 32 or a double-flow impeller 32. The fresh air component 318 has a first inlet 319, and the fresh air component 318 is connected to the air inlet bracket 315 and the housing 10 so that the first inlet 319 communicates with the fresh air inlet 124 on the housing 10. The side of the air inlet bracket 315 has a second inlet 320, and the air inlet bracket 315 is connected to the housing 10 so that the second inlet 320 communicates with the internal circulation air inlet 125 on the housing 10. The air outlet component 317 is provided on the upper side of the volute 314 and communicates with the top opening of the volute 314. The first filter assembly 33 can be installed on the air outlet component 317, and the air outlet component 317 is connected to the housing 10 so that the outlet of the air outlet component 317 communicates with the second air outlet 122.
[0078] According to some embodiments of the present invention, such as Figure 5 , Figure 9 and Figure 17 As shown, the second filter assembly 34 may include a handle portion 341 and a filter portion 342. The filter portion 342 may be located within the gas flow channel 311 to filter the gas, and the filter portion 342 may cooperate with the guide groove 312 to guide the assembly and disassembly of the second filter assembly 34. The handle portion 341 is connected to the filter portion 342 to facilitate user disassembly.
[0079] In addition, such as Figure 9 and Figures 15-16 As shown, the housing 10 may be provided with a receiving groove 13, and the receiving groove 13 is connected to the disassembly port 123. When the second filter assembly 34 is installed, the handle part 341 can be stored in the receiving groove 13 to reduce or avoid the handle part 341 protruding from the outer surface of the housing 10, thereby preventing the second filter assembly 34 from being accidentally knocked out, and also making the appearance of the air conditioner 100 neater and more beautiful.
[0080] In some embodiments of the present invention, such as Figure 15 and Figure 16 As shown, the receiving groove 13 may be provided with two guide portions 131, which are arranged opposite to each other, and the distance between the two guide portions 131 decreases along the insertion direction of the second filter assembly 34. Therefore, the opening size of the receiving groove 13 near the disassembly port 123 is larger, and the opening size of the receiving groove 13 near the guide slide 312 is smaller. This makes it easier to insert the second filter assembly 34 into the disassembly port 123 and the receiving groove 13 during installation, and it can move into the guide slide 312 under the guidance of the two guide portions 131, making alignment with the guide slide 312 easier. The receiving groove 13 also has sufficient space to accommodate the handle portion 341, making it easier for the user to pull the handle portion 341.
[0081] The present invention does not impose special limitations on the specific structure of the guide portion 131. In some embodiments of the present invention, such as Figure 16 As shown, the guide portion 131 may include at least one guide rib 132, which is disposed on the wall of the receiving groove 13. The height of the guide rib 132 protruding from the wall of the receiving groove 13 increases along the insertion direction of the second filter assembly 34, so that the spacing between the opposing guide ribs 132 decreases. The guide rib 132 has a simple structure and can improve the structural strength of the housing 10.
[0082] In other embodiments, the walls of the receiving groove 13 may extend at an angle to form a guide portion 131. For example, the two opposing walls of the receiving groove 13 may extend close to each other along the insertion direction of the second filter assembly 34, simplifying the structure of the housing 10 and allowing the second filter assembly 34 to move more smoothly along the inclined walls.
[0083] According to some embodiments of the present invention, the handle portion 341 and the housing 10 can be detachably fastened together so that when the second filter assembly 34 is installed in place, the second filter assembly 34 is stably fixed in the housing 10 by fastening the handle portion 341 to the housing 10, which is not easy to misalign, deform or fall off, and is easy to disassemble.
[0084] Specifically, such as Figures 15-18 As shown, the handle portion 341 may be provided with a fastening portion 343, and the receiving groove 13 may be provided with a fastening engagement portion 133. When the second filter assembly 34 is installed in place, the fastening portion 343 is located in the receiving groove 13 to fasten with the fastening engagement portion 133, thereby realizing the detachable connection between the second filter assembly 34 and the housing 10.
[0085] The specific structures of the fastening part 343 and the fastening engagement part 133 can be flexibly configured according to actual conditions. In some embodiments of the present invention, one of the fastening part 343 and the fastening engagement part 133 can be a spring-loaded buckle, and the other of the fastening part 343 and the fastening engagement part 133 can be provided with a fastening groove. When subjected to force (e.g., a resisting force), the spring-loaded buckle can undergo elastic deformation to move into the fastening groove, and after the force is removed, it can recover its deformation to engage and limit with the edge of the fastening groove, preventing the spring-loaded buckle from falling out of the fastening groove. The spring-loaded buckle structure facilitates frequent and repeated assembly and disassembly of the fastening part 343 and the fastening engagement part 133, has a long service life and is not prone to fatigue, and the fastening is reliable. In some specific embodiments, the other of the fastening part 343 and the fastening engagement part 133 can be a pin, which defines the fastening groove to engage with the spring-loaded buckle.
[0086] According to some embodiments of the present invention, such as Figure 18As shown, the handle portion 341 may include a base plate 344 and a connecting portion 345. The connecting portion 345 is located on the side of the base plate 344 facing the gas flow channel 311 to connect with the filter portion 342, allowing the filter portion 342 to extend into the gas flow channel 311. The base plate 344 may be located at the disassembly port 123 and close the disassembly port 123, making the appearance of the air conditioner 100 casing 10 neater and more aesthetically pleasing. The fastening portion 343 may also be located on the side of the base plate 344 facing the gas flow channel 311, so that the fastening structure can be shielded by the base plate 344 to prevent damage from contact and also to improve the appearance.
[0087] In some embodiments of the present invention, a handle groove may be provided on the side of the substrate 344 facing away from the gas flow channel 311, so that the handle groove can be exposed when the disassembly port 123 is closed, which facilitates the disassembly of the second filter assembly 34.
[0088] In some embodiments of the present invention, such as Figure 17 and Figure 18 As shown, the filter part 342 can be a filter screen, and the connecting part 345 can be connected to one side edge of the filter screen, which not only achieves connection but also helps to reduce the deformation of the filter screen. There are two fastening parts 343. In the length direction of the side edge of the filter screen connected to the connecting part 345, the two fastening parts 343 can be respectively provided on both sides of the connecting part 345. In other words, the two fastening parts 343 are respectively provided at both ends of the base plate 344 in the length direction. This not only further improves the anti-deformation effect of the filter screen, but also makes the connection between the handle and the housing 10 more reliable. The edge of the base plate 344 is not easy to lift up, and the gap between it and the edge of the disassembly port 123 is more uniform, preventing dust, hair, etc. from entering the gas flow channel 311 through this gap.
[0089] According to some embodiments of the present invention, such as Figure 15 and Figure 16 As shown, the receiving groove 13 may be provided with two positioning parts 134, which are spaced apart to divide the receiving groove 13 into an installation area 135 and a fastening area 136. A fastening engagement part 133 may be provided in the fastening area 136, and a fastening part 343 may extend into the fastening area 136 to fasten with the fastening engagement part 133. A connecting part 345 may extend into the installation area 135 so that the filter part 342 can pass through the installation area 135 and extend into the gas flow channel 311. Furthermore, the connecting part 345 may have a clearance fit with the positioning parts 134, such as a contact fit or a small gap. Thus, the two positioning parts 134 can position the connecting part 345 so that the filter part 342 connected to the connecting part 345 can align with the guide groove 312 in the gas flow channel 311, making installation easier and less prone to shaking or deformation.
[0090] An air conditioner 100 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings. It is to be understood that the following description is merely illustrative and should not be construed as limiting the invention.
[0091] According to some embodiments of the present invention, such as Figures 1-8 As shown, the air conditioner 100 may include a housing 10, a heat exchanger 18, an air duct assembly 20, a control assembly, and an air handling assembly 30. Among them, as... Figure 4 As shown, the housing 10 can be composed of a front shell, a rear housing 17, a base 19, and a top cover 14. The front shell can be composed of an upper panel 15 and a lower panel 16, and a first air outlet 112 is provided on the front shell. An air outlet switch door can be provided at the first air outlet 112 to open and close the first air outlet 112. The rear housing 17 can be composed of one or more pieces, and a first air inlet 111 can be provided on the rear housing 17. An air conditioning return air grille filter can be provided at the first air inlet 111. Columns are provided on both sides of the rear housing 17 to install and fix the evaporator, air handling unit 30, and control components. A second air outlet 122, a disassembly port 123, and a receiving slot 13 can be provided on the rear housing 17.
[0092] like Figures 4-8 As shown, the air handling assembly 30 may include a housing 31, a first filter assembly 33, a second filter assembly 34, and a fan 32. The housing 31 may include a fresh air component 318, an air inlet bracket 315, a volute 314, and an air outlet component 317. The fresh air component 318 has a first inlet 319 at its rear end and its front end connected to the rear end of the air inlet bracket 315. The air inlet bracket 315 has a second inlet 320 on its side. The rear end of the volute 314 is connected to the front end of the air inlet bracket 315. The lower end of the air outlet component 317 is connected to the upper end of the volute 314, and the left and right sides of the air outlet component 317 have outlets that communicate with two second air outlets 122 on the housing 10, respectively. Thus, the fresh air component 318, the air inlet bracket 315, the volute 314, and the air outlet component 317 cooperate to define a gas flow channel 311. The impeller 32 is a cross-flow impeller or a double cross-flow impeller. The impeller 32 is located inside the volute 314, and the rotation circumference of the impeller 32 extends in the front-to-back direction to drive the gas in the volute 314 to enter along the circumference of the impeller 32 and exit radially. This drives the outdoor gas to flow from the fresh air component 318 through the air inlet bracket 315 and into the volute 314, and drives the indoor gas to directly enter the volute 314 from the air inlet bracket 315. The gas in the volute 314 flows upward to the air outlet component 317 and finally flows out into the room through the second air outlet 122.
[0093] Furthermore, the first filter assembly 33 is installed on the air outlet component 317 and faces the upper outlet of the volute 314 to filter the gas flowing out of the volute 314. The second filter assembly 34 is installed between the volute 314 and the air inlet bracket 315 so that the indoor or outdoor gas flowing in from the second air inlet 121 is filtered by the second filter assembly 34 before flowing into the volute 314. In the gas flow direction, the second filter assembly 34 is located on the air inlet side of the impeller 32, and the first filter assembly 33 is located on the air outlet side of the impeller 32. The first inlet 319 on the fresh air component 318 is opposite to and connected to the fresh air inlet 124 on the housing 10, and the second inlet 320 on the air inlet bracket 315 is opposite to and connected to the internal circulation air inlet 125 on the housing 10, so that the fresh air inlet 124 and the internal circulation air inlet 125 are respectively connected to the gas flow channel 311. The air flowing in from the fresh air inlet 124 and the internal circulation air inlet 125 first passes through the second filter assembly 34, then through components such as the impeller 32, and flows to the first filter assembly 33, before finally flowing into the room from the second air outlet 122. This ensures that foreign objects such as hair contained in the indoor / outdoor air are filtered by the second filter assembly 34 before flowing to the first filter assembly 33, which can improve the service life of the first filter assembly 33 and make the interior of the air flow channel 311 cleaner.
[0094] like Figures 9-18 As shown, the second filter assembly 34 may include a handle portion 341 and a filter portion 342. The filter portion 342 may be a pre-filter. The handle portion 341 may include a base plate 344, pins (i.e., fastening portions 343) provided at both ends of the base plate 344, and a connecting portion 345 for mounting the filter portion 342. The second filter assembly 34 is removable and washable. A protrusion 316 is provided at the mating point of the volute 314 and the air inlet bracket 315, and the mutual engagement between the protrusions 316 forms a guide groove 312 for the second filter assembly 34. The receiving groove 13 of the housing 10 is provided with a spring clip (i.e., fastening engagement portion 133), a guide rib 132 (i.e., guide portion 131), and a positioning rib (i.e., positioning portion 134). The bottom wall of the receiving groove 13 has a through hole for the second filter assembly 34 to pass through, and the opening of the receiving groove 13 is formed as a disassembly / reassembly port 123. The positioning rib divides the receiving groove 13 into three parts: two fastening areas 136 and an installation area 135 located between the two fastening areas 136. The fastening area 136 is provided with a spring buckle, which can be detachably connected with the pin on the handle part 341 of the second filter assembly 34. The installation area 135 is provided with a guide rib 132, which allows the second filter assembly 34 to be smoothly guided into the through hole when it is installed, and then inserted into the guide groove 312 between the volute 314 and the air inlet bracket 315.
