The embodiments described below with reference to the drawings are exemplary only, and are merely intended to explain the present application, and are not to be understood as limiting the present application.

[0043] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of particular examples in the following description are set forth by referring to the drawings. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application can refer to a reference numeral and / or letter in different examples. Such repetition is for the purpose of simplification and clarity and does not indicate a relationship between the various embodiments and / or settings discussed. Furthermore, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0044] Below, with reference to the drawings, an air conditioner 2 according to an embodiment of the present application is described.

[0045] As Figures 1-7As shown, according to the air conditioner 2 of the embodiment of the utility model, the air conditioner 2 includes fresh air component 1, fresh air component 1 includes: air inlet frame 10, fan assembly 20, filter assembly 30 and first air inlet grille 40, air inlet frame 10 defines air inlet air duct 12, air inlet air duct 12 has fresh air inlet 14, fan assembly 20 includes volute 22, volute 22 is connected with air inlet frame 10, and volute 22 is limited to wind wheel cavity 224 in, wind wheel cavity 224 has air inlet 24, air inlet 24 includes first air inlet area 240 and second air inlet area 242, volute 22 and air inlet frame 10 are limited to installation cavity 26 between, or, air inlet frame 10 defines installation cavity 26, installation cavity 26 is communicated with air inlet air duct 12, and installation cavity 26 has pullout opening 28, filter assembly 30 is installed in installation cavity 26 through pullout opening 28 and can be pulled, relative to second air inlet area 242, first air inlet area 240 is adjacent pullout opening 28 and is arranged, first air inlet grille 40 covers first air inlet area 240, and first air inlet grille 40 does not cover second air inlet area 242, so that wind wheel cavity 224 is indirectly communicated between first air inlet area 240 and installation cavity 26 through first air inlet grille 40, and wind wheel cavity 224 is directly communicated between second air inlet area 242 and installation cavity 26 through air inlet 24. It can be understood that installation cavity 26 can be defined by the empty space left when volute 22 and air inlet frame 10 are assembled, that is, installation cavity 26 can be defined by volute 22 and air inlet frame 10 together; or, air inlet frame 10 leaves a part of empty space for defining installation cavity 26 when processing, then installation cavity 26 can be defined by air inlet frame 10 alone, so that the setting position of filter assembly 30 is more flexible.

[0046] It can be seen that the volute 22 is connected with the air inlet frame 10, the air inlet 24 of the volute 22 is communicated with the air inlet duct 12 through the mounting cavity 26, and the filter assembly 30 is arranged in the mounting cavity 26 between the volute 22 and the air inlet frame 10. When the fan assembly 20 works normally, the external fresh air can enter the air inlet duct 12 from the fresh air inlet 14, pass through the mounting cavity 26, be filtered by the filter assembly 30, and then be sucked into the air inlet 24 of the volute 22, so that the fresh air function is realized, and the filter assembly 30 can process the fresh air. The filter assembly 30 is arranged in the mounting cavity 26 in a pullable manner through the pull-out opening 28, so that the user can clean or replace the filter assembly 30 without disassembling the entire fresh air component 1, the convenience and efficiency of maintenance are improved, and the removal of the filter assembly 30 does not affect the normal work of other components, the downtime maintenance time of the fresh air component 1 is reduced, and the user experience is improved. For example, when the filter assembly 30 needs to be maintained or cleaned, the user only needs to simply take out the filter assembly 30 from the pull-out opening 28 without closing the entire fresh air component 1 or disassembling other components, that is, the filter assembly 30 is taken out for cleaning or replacement while the fan assembly 20 can still maintain normal operation, and when the filter assembly 30 is cleaned or replaced, the user places the filter assembly 30 in the mounting cavity 26 through the pull-out opening 28, so that the filter assembly 30 can filter the external fresh air again, thereby reducing the downtime maintenance time of the fresh air component 1 and improving the user experience.

[0047] In addition, due to the arrangement of the first air inlet area 240 and the second air inlet area 242, part of the airflow at the air inlet 24 flows to the impeller cavity 224 through the first air inlet area 240, and part of the airflow at the air inlet 24 flows to the impeller cavity 224 through the second air inlet area 242. Among them, compared with the second air inlet area 242, the first air inlet area 240 is closer to the pull-out opening 28, and the distance between the first air inlet area 240 and the pull-out opening 28 is less than the distance between the second air inlet area 242 and the pull-out opening 28; for example, in combination with Figures 2-4 In the pull-out direction of the filter assembly 30, the first air inlet area 240 is located between the second air inlet area 242 and the pull-out opening 28.

[0048] It can be seen that, compared with the second air inlet area 242, the user is more likely to contact the first air inlet area 240 by inserting the finger into the pull opening 28, and the first air inlet grille 40 covers the first air inlet area 240, so that after the user contacts the first air inlet area 240 by inserting the finger into the pull opening 28, the first air inlet grille 40 can block the finger from contacting the internal structure of the wind wheel cavity 224 such as the wind wheel 2242 to cause a cut, thereby improving the safety of the fresh air component 1 to meet the safety requirements of the fresh air component 1; similarly, compared with the first air inlet area 240, the user is less likely to contact the second air inlet area 242 by inserting the finger into the pull opening 28, and the first air inlet grille 40 does not cover the second air inlet area 242, thereby facilitating the reduction of air resistance of the airflow passing through the second air inlet area 242, so that the airflow can flow more smoothly through the second air inlet area 242 to the wind wheel cavity 224, thereby facilitating the increase of the air intake of the fresh air component 1 and improving the performance of the fresh air component 1. In other words, if the first air inlet area 240 and the second air inlet area 242 are both covered by the first air inlet grille 40, the wind wheel cavity 224 is indirectly communicated with the mounting cavity 26 through the first air inlet grille 40 at the first air inlet area 240 and the second air inlet area 242, although the first air inlet grille 40 can effectively block the finger from contacting the fan blade, the air intake resistance at the air inlet 24 is relatively large, so that the air intake at the air inlet 24 is relatively low, and the above-mentioned setting of the present application can meet the safety requirements while taking into account the reduction of air intake resistance.

[0049] Exemplarily, after the fresh air component 1 is used for a period of time, a lot of dust and impurities may accumulate on the filter assembly 30, so that the filtering effect of the filter assembly 30 is poor, and the user can take out the filter assembly 30 through the pull opening 28 for cleaning or replacement. At this time, the idle pull opening 28 allows the user to insert the finger into the pull opening 28 to contact the first air inlet area 240, and the first air inlet grille 40 provided at the first air inlet area 240 makes it difficult for the finger to contact the internal structure of the wind wheel cavity 224 through the first air inlet grille 40 to cause a cut, thereby facilitating the improvement of the safety of the fresh air component 1, and the first air inlet grille 40 does not cover the second air inlet area 242 which is not easy to contact or cannot be contacted by the user's finger, thereby facilitating the reduction of the resistance at the air inlet 24 and facilitating the improvement of the air intake of the fresh air component 1.

[0050] As Figures 2-4As shown, in some embodiments, the closest distance between the edge of the first air intake grille 40 furthest from the pull-out opening 28 and the pull-out opening 28 is L1, where L1 ≥ 60 mm; and / or, the minimum width of the pull-out opening 28 is B1, where B1 ≤ 20 mm, so that the first air intake grille 40 has sufficient length to prevent the user from easily touching the second air intake area 242 when inserting their finger through the pull-out opening 28. The first air intake grille 40 can effectively prevent fingers from contacting the internal structure of the fan assembly 20, thereby improving the safety of the fresh air component 1. For example, L1 is 60 mm, 75 mm, 90 mm, 125 mm, 140 mm, 165 mm, 18 mm, etc. 2mm, 212mm, 234mm, 251mm, 274mm, 286mm, 300mm, etc.; and / or, the minimum width of the pull-out port 28 is less than or equal to 40mm, so that the pull-out port 28 has sufficient operating space to facilitate the user to put in and take out the filter component 30, while restricting the user from putting their palm or arm further into the pull-out port 28, making it less likely for the user to come into contact with the second air inlet area 242 and cause cuts, so as to further improve the safety of the fresh air component 1. For example, B1 is 5mm, 8mm, 13mm, 18mm, 21mm, 26mm, 32mm, 34mm, 38mm, 40mm, etc.

[0051] It is understandable that when L1≥60mm and B1≤40mm, in the safety test using the safety finger (Type B test bar) fixture, the pull-out port 28 can better limit the length of the safety finger fixture that extends into the pull-out port 28. At the same time, in conjunction with the size of the first air inlet grille 40, the fingertip of the safety finger fixture cannot contact the second air inlet area 242.

[0052] like Figures 5-7 As shown, in some embodiments, the first air inlet grille 40 includes a plurality of first ribs 44 spaced apart along a first direction, each first rib 44 extending along a second direction, and defining at least one grille opening 42 between adjacent two first ribs 44. The size of the grille opening 42 in the first direction (e.g., Figure 7 d1) is less than or equal to its dimension in the second direction (e.g., Figure 7 The maximum dimension of the grid hole 42 in the first direction is d1, where d1 ≤ 8 mm, and the first direction intersects with the second direction.

[0053] It can be seen that the first air inlet grille 40 has a plurality of first ribs 44 arranged at intervals in the first direction, and each first rib 44 extends in the second direction, and the first direction and the second direction intersect, so that the two adjacent first ribs 44 define at least one grille hole 42, so that the structure of the first air inlet grille 40 is relatively simple, facilitating processing and manufacturing, and the plurality of first ribs 44 enhances the structural strength of the first air inlet grille 40, which can effectively resist external pressure or deformation, improve the stability and durability of the first air inlet grille 40, and the size of the grille hole 42 in the first direction is smaller than the size of the grille hole 42 in the second direction, that is, the finger is not easy to pass through the grille hole 42 to contact the inside of the wind wheel cavity 224 to cause a cut, which facilitates improving the safety of the fresh air component 1.

[0054] In addition, by setting the maximum size of the grille hole 42 in the first direction to be less than or equal to 8 mm, the finger is not easy to pass through the grille hole 42 to contact the fan blade, which facilitates improving the safety of the fresh air component 1, for example, d1 is 2 mm, 2.5 mm, 3.2 mm, 3.8 mm, 4.2 mm, 4.6 mm, 5.1 mm, 5.7 mm, 6 mm, 6.6 mm, 7.2 mm, 7.8 mm, 8 mm, etc.

[0055] In the embodiments of the present application, the shape of the grille hole 42 is not specifically limited and can be polygonal, circular, etc. Figures 2-6 In the example, the grille hole 42 is arc-shaped, and in the example, the grille hole 42 is rectangular. Figure 7

[0056] As shown in Figure 8 In some embodiments, the pull-out opening 28 is arranged at intervals on the outer circumferential side of the air inlet 24, and the pull-out opening 28 is located on one side of the first air inlet grille 40 in the first direction or the second direction, that is, the pull-out opening 28 can be flexibly arranged on any one side of the four sides of the first air inlet grille 40, so that the setting position of the pull-out opening 28 is more flexible, facilitating adaptation to different installation environments; or, as shown in Figures 2-6 The pull-out opening 28 is arranged at intervals on the outer circumferential side of the air inlet 24, one of the first direction and the second direction is the circumferential direction of the air inlet 24, and the other is the radial direction of the air inlet 24, that is, the plurality of first ribs 44 are arranged at intervals in the radial direction of the air inlet 24 and each first rib 44 extends in the circumferential direction of the air inlet 24, or the plurality of first ribs 44 are arranged at intervals in the circumferential direction of the air inlet 24 and each first rib 44 extends in the radial direction of the air inlet 24, so that the setting form of the first rib 44 is more flexible.

[0057] As shown in Figures 5-7 ​As shown, in some embodiments, the first air inlet grille 40 further comprises a plurality of second ribs 46 arranged in the second direction, and the first ribs 44 and the second ribs 46 are arranged in intersection to define the grille holes 42. By arranging the second ribs 46 to intersect with the first ribs 44, the structural strength of the first air inlet grille 40 is enhanced, which helps to improve the ability of the first air inlet grille 40 to resist external pressure or vibration, thereby improving the reliability of the first air inlet grille 40 in operation.

[0058] In some embodiments, the first direction and the second direction are perpendicular.

[0059] For example, as shown in Figure 1 , Figure 7 , the first direction is the left-right direction of the fresh air component 1, the second direction is the up-down direction of the fresh air component 1, the first ribs 44 all extend in the up-down direction of the fresh air component 1, and the plurality of first ribs 44 are arranged in the left-right direction of the fresh air component 1, the second ribs 46 all extend in the left-right direction of the fresh air component 1, and the plurality of first ribs 44 are arranged in the up-down direction of the fresh air component 1, so that the first ribs 44 and the second ribs 46 arranged in intersection define the grille holes 42, so that the grille holes 42 are rectangular or square in shape, and the structure is relatively simple, facilitating processing and manufacturing. Among them, the pull-out opening 28 is located on the side of the first air inlet area 240 away from the second air inlet area 242 in the left-right direction of the fresh air component 1, so that the user is not easy to touch the second air inlet area 242, facilitating the safety of the fresh air component 1 in operation.

[0060] For another example, as shown in Figure 2 , Figure 5 , and Figure 6 , the first direction is the radial direction of the air inlet 24, the second direction is the circumferential direction of the air inlet 24, the first ribs 44 all extend in the circumferential direction of the air inlet 24, and the plurality of first ribs 44 are arranged in the radial direction of the air inlet 24, the second ribs 46 all extend in the radial direction of the air inlet 24 of the fresh air component 1, and the plurality of first ribs 44 are arranged in the circumferential direction of the air inlet 24 of the fresh air component 1, so that the first ribs 44 and the second ribs 46 arranged in intersection define the grille holes 42, so that the grille holes 42 are quadrilaterals in shape, and the structure is relatively simple, facilitating processing and manufacturing. Among them, the pull-out opening 28 is located on the side of the first air inlet area 240 away from the second air inlet area 242 in the radial direction of the air inlet 24, so that the user is not easy to touch the second air inlet area 242, facilitating the safety of the fresh air component 1 in operation.

[0061] For example, when the fresh air component 1 is applied to the air conditioner 2, the first direction can be the left-right direction of the air conditioner 2, the second direction can be the up-down direction of the air conditioner 2, and the pull-out opening 28 is located on the side of the first air inlet area 240 away from the second air inlet area 242 in the left-right direction of the air conditioner 2.

[0062] AsFigures 2-8 As shown, in some embodiments, the fresh air component 1 is configured to meet at least one of the following conditions A1 and A2:

[0063] In condition A1, the first air inlet grille 40 is configured as a flat grille, the structure of the first air inlet grille 40 is relatively simple, which is convenient for processing and forming, or the first air inlet grille 40 is configured as a convex curved grille facing the air inlet frame 10, which is convenient for increasing the distance between the first air inlet grille 40 and the first air inlet 24, so that the user's fingers are not easy to contact the air inlet cavity to cause cuts, and at the same time, the convex curved grille can increase the flow area of the first air inlet grille 40, so as to increase the air inlet amount of the first air inlet 24 and improve the user's use experience.

[0064] In condition A2, the filter assembly 30 is opposite to the air inlet 24, so that the first air inlet area 240 and the second air inlet area 242 are respectively opposite to different parts of the filter assembly 30, that is, the air flow passing through the first air inlet area 240 and the second air inlet area 242 can be fully filtered by the filter assembly 30, so that the air quality output by the fresh air component 1 is better. The filter assembly 30 includes a filter screen support 32 and a filter screen core 34, the filter screen core 34 is installed on the filter screen support 32, the filter screen core 34 is arc-shaped and is convexly arranged in a direction away from the air inlet 24, which is convenient for increasing the filtering area of the filter screen assembly, so as to have better filtering effect of the filter assembly 30. It can be understood that the connection mode between the filter screen core 34 and the filter screen support 32 is not limited specifically, for example, the filter screen core 34 and the filter screen support 32 can be detachably connected, so that when the user needs to clean the filter screen assembly, the filter screen core 34 can be detached from the filter screen support 32, and the filter screen core 34 and the filter screen support 32 can be cleaned respectively, which is convenient for improving the cleanliness of the filter assembly 30, and when the filter screen assembly needs to be replaced, the user can only replace the filter screen core 34, which is convenient for reducing the maintenance cost of the filter assembly 30.

[0065] Optionally, the filter screen core 34 is a Hepa screen, which is mainly used for filtering small particulate matters in the air, such as dust, pollen, bacteria, viruses and other particles, and can effectively capture particles with a diameter of 0.3 microns or more. The Hepa screen has high filtering capacity and can filter allergens and pathogens in the air to ensure the cleanliness of the air. By using the Hepa screen as the filter screen core 34, the filtering effect of the filter screen assembly can be improved.

[0066] As Figures 2-4As shown, in some embodiments, the fresh air component 1 satisfies condition A2. The cavity wall of the mounting cavity 26 is provided with a first guide rib 260 and a second guide rib 262 that are spaced apart along the axial direction of the air inlet 24 and extend in an arc shape. The filter assembly 30 is slidably fitted between the first guide rib 260 and the second guide rib 262. One of the first guide rib 260 and the second guide rib 262 is formed on the air inlet frame 10, and the other is formed on the volute 22. At this time, the mounting cavity 26 is limited between the volute 22 and the air inlet frame 10.

[0067] As can be seen, the first guide rib 260 and the second guide rib 262 define the track for the sliding engagement of the filter assembly 30. That is, the assembly of the air inlet frame 10 and the volute 22 can form a track for the sliding engagement of the filter assembly 30. The track is arc-shaped, and the filter assembly 30 is also arc-shaped, so that the shape of the filter assembly 30 and the shape of the track can be better matched, which facilitates the installation of the filter assembly 30. When the user needs to clean or replace the filter assembly 30, the filter assembly can be pulled out from the pull-out port 28 with an arc-shaped movement trajectory, which reduces the space required for the user to disassemble and install the filter assembly 30, so that the fresh air component 1 can adapt to different installation environments.

[0068] Furthermore, one of the first guide rib 260 and the second guide rib 262 is formed on the air inlet frame 10, and the other is formed on the volute 22. For example, the first guide rib 260 is located on the air inlet frame 10, and the second guide rib 262 is located on the volute 22, or the first guide rib 260 is located on the volute 22, and the second guide rib 262 is located on the air inlet frame 10. This facilitates reducing the processing difficulty of the first guide rib 260 and the second guide rib 262 and improving production efficiency.

[0069] like Figures 2-4 As shown, in some embodiments, the first air intake grille 40 is integrally connected to the volute 22, for example, the first air intake grille 40 is integrally connected to the peripheral wall of the air inlet 24; the fresh air component 1 also includes an air guide ring 50, which is arranged around the air inlet 24, and the windward end 52 of the air guide ring 50 is integrally connected to the first air intake grille 40 and the volute 22, and the diameter of the air guide ring 50 is smaller than the diameter of the impeller 2242 of the fan assembly 20.

[0070] As can be seen, the air guide ring 50 is arranged around the air inlet 24. The air guide ring 50 can guide the airflow to enter the impeller 2242 of the fan assembly 20 more smoothly. By reducing the turbulence and eddies of the airflow at the air inlet 24, the straightness and stability of the airflow can be improved, so that more airflow can be effectively captured and accelerated by the impeller 2242, which helps to improve the overall airflow efficiency and performance of the fresh air component 1.

[0071] In addition, the air guide ring 50 is integrally connected to the first air inlet grille 40 and the volute 22, so that the first air inlet grille 40, the air guide ring 50 and the volute 22 form an integral whole, thereby facilitating the structural strength of the first air inlet grille 40 when matched with the volute 22, so that the fresh air component 1 can obtain more stable working effect.

[0072] The diameter of the air guide ring 50 is smaller than the diameter of the wind wheel 2242, so that the air guide ring 50 can more smoothly guide the airflow into the wind wheel 2242, further reducing the possibility of turbulence and vortex of the airflow at the air inlet 24, so that the airflow passing through the air inlet 24 is not easy to produce abnormal sound phenomenon, improving the sound quality of the fresh air component 1.

[0073] As shown in Figures 2-4 and Figure 8 , in some embodiments, the volute 22 includes a volute body 220 and a volute cover plate 222, the wind wheel cavity 224 and the air inlet 24 are formed on the volute body 220, the volute cover plate 222 is arranged outside the volute body 220, and the volute cover plate 222 and the volute body 220 define a sound attenuation cavity 226, and the volute body 220 is formed with a plurality of sound attenuation holes 228 communicating the wind wheel cavity 224 and the sound attenuation cavity 226.

[0074] As can be seen, the volute body 220 has the wind wheel cavity 224 communicating with the air inlet 24, the wind wheel cavity 224 provides a relatively closed environment for the operation of the wind wheel 2242, reducing the possibility of foreign matter entering to affect the normal operation of the wind wheel 2242; the volute cover plate 222 and the volute body 220 define the sound attenuation cavity 226, and the plurality of sound attenuation holes 228 communicate the wind wheel cavity 224 and the sound attenuation cavity 226, part of the airflow flowing through the wind wheel cavity 224 enters the sound attenuation cavity 226 through the sound attenuation holes 228, at the same time, a gas column is formed at the sound attenuation holes 228, and resonance is formed with the airflow at the wind wheel cavity 224, converting sound energy into heat energy dissipation, reducing the audible sound component, facilitating the reduction of noise during operation of the fresh air component 1.

[0075] As shown in Figures 2-4 and Figure 8 , in some embodiments, the fan assembly 20 further includes a motor 2240 and a wind wheel 2242 arranged in the wind wheel cavity 224, the motor 2240 is mounted on the volute body 220 and connected with the wind wheel 2242, the volute cover plate 222 is arranged on the side of the volute body 220 axially away from the air inlet frame 10, the volute body 220 forms a limiting groove 221, the sound attenuation holes 228 are formed on the groove bottom wall of the limiting groove 221, the plurality of sound attenuation holes 228 are arranged around the motor 2240, and the volute cover plate 222 is limitedly matched with the limiting groove 221.

[0076] It can be seen that the motor 2240 is mounted on the volute body 220, and the motor 2240 is connected with the wind wheel 2242. The motor 2240 can drive the wind wheel 2242 to rotate to drive the airflow to flow. The volute body 220 forms a limiting groove 221, which is open on the side away from the air inlet frame 10. The volute cover plate 222 is limitedly fitted in the limiting groove 221, which reduces the assembly difficulty of the volute cover plate 222 and the volute body 220, and facilitates to improve the production efficiency. A plurality of sound holes 228 are arranged around the motor 2240, that is, the area where the motor 2240 is arranged is not provided with sound holes 228, so that the area where the motor 2240 is arranged has good structural strength, so that the motor 2240 can work more stably.

[0077] As shown in Figures 2-4 and Figure 8 In some embodiments, the limiting groove 221 has a mounting portion 2210 formed on the groove bottom wall. The mounting portion 2210 is outwardly protruding, and the mounting portion 2210 defines a mounting groove 2212 in the wind wheel cavity 224 for accommodating the motor 2240. The mounting portion 2210 has a threading hole 2214 for threading the connecting line of the motor 2240. The volute cover plate 222 has a through hole 2220, and the mounting portion 2210 is fitted in the through hole 2220. The threading hole 2214 is exposed to the volute cover plate 222.

[0078] It can be seen that the motor 2240 is adapted to be mounted in the mounting groove 2212 defined by the mounting portion 2210 in the wind wheel cavity 224, which facilitates to make full use of the space of the wind wheel cavity 224 and the sound hole cavity 226, so that the structure of the fresh air component 1 is more compact, facilitating to realize the miniaturization of the fresh air component 1. At the same time, the mounting portion 2210 is outwardly protruding, and a plurality of sound holes 228 can be arranged at intervals around the outer circumferential side of the mounting portion 2210, which facilitates to be quickly aligned and fitted in the through hole 2220, and realizes the quick assembly of the volute body 220 and the volute cover plate 222.

[0079] In addition, the mounting portion 2210 is fitted in the through hole 2220 formed in the volute cover plate 222, so that the threading hole 2214 is exposed to the volute cover plate 222. The connecting line of the motor 2240 can pass through the threading hole 2214 to extend to the outside of the wind wheel cavity 224, facilitating the wiring arrangement of the connecting line, and providing more operation space for the staff to install or maintain the connecting line of the motor 2240, without the need to disassemble too many components, facilitating to improve the efficiency of installation or maintenance of the connecting line.

[0080] As shown in Figures 2-4 and Figure 8As shown, in some embodiments, the air intake duct 12 further includes an indoor air inlet 16. The fresh air component 1 includes a second air intake grille 60, which is disposed at the indoor air inlet 16. The air conditioner 2 also includes a rear housing 70, a first valve 77, and a second valve 78. At least the air intake frame 10 is disposed inside the rear housing 70. The rear housing 70 has a first inlet 72, a second inlet 74, and an opening 76 that are spaced apart. The first inlet 72 is opposite to the fresh air inlet 14, the second inlet 74 is opposite to the indoor air inlet 16, and the opening 76 is opposite to the pull-out port 28. The first valve 77 is movably disposed at the fresh air inlet 14 to open or close the fresh air inlet 14 or the first inlet 72. The second valve 78 is movably disposed at the second inlet 74 to open or close the second inlet 74. The second air intake grille 60 is recessed inward in a direction away from the second valve 78.

[0081] As can be seen, the second air inlet grille 60 is located at the indoor air inlet 16. The second air inlet grille 60 can block foreign objects from entering the indoor air inlet 16 to a certain extent, which helps to improve the stability of the operation of the fresh air component 1. The rear housing 70 has a first inlet 72, a second inlet 74 and an opening 76 arranged at intervals, which correspond one-to-one with the fresh air inlet, the indoor air inlet 16 and the pull-out opening 28, respectively. The first valve 77 can control the opening and closing of the fresh air inlet 14 or the first inlet 72, and the second valve 78 can control the opening and closing of the second inlet 74, so that outdoor fresh air and / or indoor air can flow into the air inlet duct 12 and be purified by the filter component 30. By controlling the first valve 77 and the second valve 78, it is easy to adapt to different usage environments and needs of the fresh air component 1. For example, when the indoor air quality is good, the first valve 77 can be closed and only the second valve 78 can be opened to use the indoor air inlet 16 for circulation ventilation. When the indoor air quality is poor, the first valve 77 can be opened to allow fresh air to enter the room through the fresh air inlet 14.

[0082] In addition, the second air intake grille 60 is recessed in the direction away from the second valve 78 to provide more clearance for the movement of the second valve 78, thereby reducing the possibility of interference between the second valve 78 and the second air intake grille 60 and improving the stability of the operation of the fresh air component 1.

[0083] like Figures 2-4 and Figure 8 As shown, in some embodiments, the air intake duct 12 has multiple indoor air inlets 16, and the rear housing 70 has multiple second air intake grilles 60, multiple second inlets 74 and multiple second valves 78. Each indoor air inlet 16 corresponds to a second air intake grille 60, a second inlet 74 and a second valve 78, so that the fresh air component 1 can easily adapt to different installation environments.

[0084] Exemplarily, the fresh air component 1 is installed on an air conditioner cabinet, due to the limitation of the installation environment of the air conditioner cabinet, a plurality of indoor air inlets 16 are arranged, so that at least part of the indoor air inlets 16 are not blocked, so that the fresh air component 1 has good air inlet capacity, and the use experience of the user is improved.

[0085] As shown in Figures 2-4 and Figure 8 , in some embodiments, the filter assembly 30 has a handle portion 36 located outside the pull-out opening 28, and the air conditioner 2 further comprises a rear shell 70, the air inlet frame 10 and the fan assembly 20 are arranged in the rear shell 70, the rear shell 70 is formed with a first inlet 72 and an opening 76 arranged at intervals, the first inlet 72 is opposite to the fresh air inlet 14, the opening 76 is opposite to the pull-out opening 28, the handle portion 36 is arranged at the opening 76, and the outer surface of the handle portion 36 is flush with the outer surface of the rear shell 70, or the outer surface of the handle portion 36 is arranged in a concave manner relative to the outer surface of the rear shell 70.

[0086] It can be seen that the filter assembly 30 also has a handle portion 36 located outside the pull-out opening 28, so that the user can more easily hold and pull the filter assembly 30, thereby facilitating cleaning or replacing the filter assembly 30; the air inlet frame 10 and the fan assembly 20 are arranged in the rear shell 70, so that the rear shell 70 can protect the air inlet frame 10 and the fan assembly 20 to some extent, so that the fresh air component 1 is more stable during operation; the opening 76 is opposite to the pull-out opening 28, and the handle portion 36 is arranged at the opening 76, so that the user can take out the filter assembly 30 through the opening 76, thereby reducing the possibility of interference between the filter assembly 30 and the rear shell 70 when taking and placing the filter assembly 30.

[0087] In addition, the outer surface of the handle portion 36 is flush with the outer surface of the rear shell 70, which facilitates reducing accidental damage of the handle portion 36 caused by collision or friction, and at the same time makes the appearance of the entire fresh air component 1 more uniform and coordinated, thereby improving the user's use experience, or the outer surface of the handle portion 36 is arranged in a concave manner relative to the outer surface of the rear shell 70, so that the handle portion 36 is more concealed, thereby reducing the risk of accidentally touching the handle portion 36 and causing the filter assembly 30 to move accidentally during use, so that the fresh air component 1 is more stable during operation.

[0088] As shown in Figure 3 and Figure 3 , in some embodiments, the fresh air component 1 is configured to satisfy at least one of the following conditions C1-C3:

[0089] In condition C1, the minimum distance between the side edge of the first air inlet grille 40 far away from the drawer opening 28 and the opening 76 is L2, L2≥80mm, so that the side edge of the first air inlet grille 40 far away from the drawer opening 28 has sufficient distance from the opening 76, which facilitates reducing the possibility of the user's fingers contacting the second air inlet area 242 and improving the safety of the fresh air component 1.

[0090] In condition C2, the minimum width of the opening 76 is B2, B2≤20mm, so that the opening 76 has sufficient operation space, which facilitates the user to take and place the filter assembly 30, while being able to limit the user from further extending the palm into the opening 76, so that the user is not easy to contact the second air inlet area 242 to cause cuts, which facilitates improving the safety of the fresh air component 1.

[0091] In condition C3, the handle part 36 includes a first handle plate 360 and a second handle plate 362, the second handle plate 362 is arranged adjacent to the opening 76, and the second handle plate 362 is bent and connected to the edge of the first handle plate 360, so that the first handle plate 360 and the second handle plate 362 define a hand holding groove 364 with the slot opening toward one side of the width direction of the opening 76, and the end of the second handle plate 362 far away from the first handle plate 360 is formed with a hand holding avoiding groove 366 in communication with the hand holding groove 364, the depth (such as L3 in Figures 2-4 ) of the hand holding avoiding groove 366 is less than the width (such as L4 in Figures 2-4 ) of the second handle plate 362.

[0092] It can be seen that the second handle plate 362 is bent and connected to the first handle plate 360 to define the hand holding groove 364 with the slot opening toward one side of the width direction of the opening 76, which provides a clear gripping area for the user and facilitates the user to take and place the filter assembly 30; the second handle plate 362 is further formed with the hand holding avoiding groove 366 in communication with the hand holding groove 364, and the depth of the hand holding avoiding groove 366 is less than the width of the second handle plate 362, i.e. the part of the second handle plate 362 forming the hand holding avoiding groove 366 has a certain empty space with the end of the opening 76, so that the user can more conveniently contact the hand holding groove 364 through the hand holding avoiding groove 366, which provides more operation space for the user.

[0093] As Figure 9As shown, in some embodiments, the fresh air component 1 satisfies C1, and the closest distance between the side edge of the first air inlet grille 40 away from the pull-out port 28 and the opening 76 is L2, where L2 ≤ 300 mm. By setting the closest distance between the side edge of the first air inlet grille 40 away from the pull-out port 28 and the opening 76 in the range of 60 mm to 300 mm, sufficient distance is provided between the side edge of the first air inlet grille 40 away from the pull-out port 28 and the opening 76, which facilitates the improvement of the safety of the fresh air component 1. At the same time, the first air inlet grille 40 will not occupy too much space in the fresh air component 1, affecting the arrangement of other components or increasing the air intake resistance of the first air inlet 24. For example, L2 is 80 mm, 85 mm, 90 mm, 125 mm, 140 mm, 165 mm, 182 mm, 212 mm, 234 mm, 251 mm, 274 mm, 286 mm, 300 mm, etc.

[0094] like Figure 10 As shown, in some embodiments, the fresh air component 1 satisfies C2, and the minimum width of the opening 76 is B2, where B2 ≥ 5mm. By setting the minimum width of the opening 76 within the range of 5mm to 20mm, the pull-out port 28 has sufficient operating space to facilitate the user's placement and removal of the filter component 30. At the same time, the thickness of the filter component 30 is not excessively restricted, so that the filter component 30 has a good filtration effect. Moreover, it can limit the user from further inserting their palm into the pull-out port 28, making it less likely for the user to come into contact with the second air intake area 242 and cause cuts, thus improving the safety of the fresh air component 1. For example, B2 is 5mm, 7mm, 8mm, 11mm, 13mm, 14mm, 16mm, 17mm, 19mm, 20mm, etc.

[0095] In some embodiments, the air conditioner 2 includes a humidifying component 80, a purifying component 82, and a fresh air component 1, wherein the fresh air component 1, the purifying component 82, and the humidifying component 80 are arranged sequentially along the airflow direction.

The purification component 82 further purifies and filters the air to remove harmful substances. Finally, the humidification component 80 humidifies the air as needed to ensure that the indoor air humidity is suitable, which helps to improve the user experience. At the same time, the fresh air component 1 has good safety, so that it can provide fresh air to the air handling unit more safely, which helps to improve the safety of the air conditioner 2.
