[0049] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0050] Reference below Figure 1-Figure 16 An air conditioner according to an embodiment of the present utility model is described.

[0051] Reference Figure 6 and Fig.11 According to the air conditioner of the embodiment of the utility model, the air conditioner includes a housing assembly 1, an air duct component 3, a heat exchanger component 4 and a lower filter 2. The air duct component 3 and the heat exchanger component 4 are arranged in the housing assembly 1, and a second air inlet 12 is formed at the bottom of the housing assembly 1. The lower filter 2 is detachably mounted on the bottom of the housing assembly 1 and covers the second air inlet 12. An air outlet 512 is formed on the housing assembly 1. The second air inlet 12 is formed at the bottom of the housing assembly 1, and air can be taken in from the bottom of the housing assembly 1. The airflow entering from the bottom of the housing assembly 1 can be filtered through the lower filter 2. The lower filter 2 can filter dust and other impurities in the airflow entering the housing assembly 1 from the second air inlet 12 to improve the air quality. The airflow entering the housing assembly 1 through the second air inlet 12 can exchange heat in the heat exchanger component 4, and the airflow after the heat exchange is blown out to the room through the air outlet 512 to cool or heat the room.

[0052] For example, an air flow inlet 31 and an air flow outlet are formed on the air duct component 3. When the air duct component 3 is working, the air flow can be driven to enter the casing assembly 1 through the second air inlet 12. In the process of the air flow entering the casing assembly 1 through the second air inlet 12, the air flow is filtered by the lower filter 2 and then enters the casing assembly 1. It enters the air duct component 3 through the air flow inlet 31 and flows from the air flow outlet to the heat exchanger component 4 for heat exchange. The air flow after heat exchange is blown into the room through the air outlet 512 to cool down or heat up the room.

[0053] The side wall of the housing assembly 1 is formed with a disassembly opening 11, through which the lower filter 2 can be installed into the housing assembly 1 or removed from the housing assembly 1. When the lower filter 2 needs to be disassembled, the lower filter 2 can be taken out or put into the housing assembly 1 through the disassembly opening 11.

[0054] It should be explained that the wall of the casing assembly 1 includes the side wall of the casing assembly 1, the bottom wall of the casing assembly 1 and the top wall of the casing assembly 1, and the side wall of the casing assembly 1 is connected between the bottom wall of the casing assembly 1 and the top wall of the casing assembly 1 and defines together with the bottom wall of the casing assembly 1 and the top wall of the casing assembly 1 a receiving cavity for receiving the fan component and the heat exchanger component 4. The side wall of the casing assembly 1 includes at least one of the left side wall, the right side wall, the front side wall and the rear side wall of the casing assembly 1.

[0055] Among them, the lower filter 2 can be detachably installed at the bottom of the casing assembly 1 and cover the second air inlet 12. The lower filter 2 can be installed into the casing assembly 1 through the disassembly and assembly port 11 or can be removed from the casing assembly 1 through the disassembly and assembly port 11, which can facilitate the maintenance, disassembly, cleaning or replacement of the lower filter 2.

[0056] For example, the installation process of the lower filter 2 may be as follows: insert the lower filter 2 from the disassembly opening 11 and push the lower filter 2 in a direction close to the bottom of the housing assembly 1, so that the lower filter 2 covers the second air inlet 12, and the installation process of the lower filter 2 is completed. The removal process of the lower filter 2 may be as follows: pull the lower filter 2 from the disassembly opening 11 in a direction away from the bottom of the housing assembly 1, so that the entire lower filter 2 is pulled out from the disassembly opening 11, and the removal process of the lower filter 2 is completed.

[0057] Optionally, the air conditioner may be a split-type floor-standing air conditioner, and the air conditioner may include an air conditioner indoor unit 100 and an air conditioner outdoor unit, and the air conditioner indoor unit 100 includes the above-mentioned casing assembly 1, air duct component 3, heat exchanger component 4 and lower filter 2.

[0058] For example, in some embodiments of the present invention, refer to Figure 1 and Figure 6The air conditioner is a split-type floor-standing air conditioner. The casing assembly 1 of the air conditioner indoor unit 100 includes a front casing component 5, a rear casing component 6, a top cover 8 and a base 7. The front casing component 5 and the rear casing component 6 are both arranged on the base 7. The front casing component 5 is connected to the rear casing component 6 and the front casing component 5 is connected to the front side of the rear casing component 6. The top cover 8 is arranged on the top of the front casing component 5 and the rear casing component 6.

[0059] The front shell component 5 includes an air outlet frame assembly 51 and an air inlet frame assembly 1a. The air outlet frame assembly 51 is arranged above the air inlet frame assembly 1a and connected to the air inlet frame assembly 1a. The air outlet frame assembly 51 includes an air outlet frame 511 and an air guide plate 513. The front side of the air outlet frame 511 is formed with an air outlet 512, and the air guide plate 513 is rotatably arranged at the air outlet 512. The air inlet frame assembly 1a includes an air inlet frame 10 and an outer air inlet grille 16. The left and right sides of the air inlet frame 10 are formed with a first air inlet 15. The lower area of ​​the first air inlet 15 is formed with a disassembly port 11. The bottom of the air inlet frame 10 is also formed with a second air inlet 12. The outer grille component is installed at the first air inlet 15. An inner air inlet grille 17 is further provided in the air inlet frame 10. The inner air inlet grille 17 is adjacent to the first air inlet port 15 and is arranged substantially opposite to the first air inlet port 15. At least a portion of an air inlet cavity is defined in the air inlet frame 10, and the inner air inlet grille 17 is located in the air inlet cavity.

[0060] An air inlet notch 71 extending in the left-right direction is formed at the front end of the base 7. The air inlet notch 71 is located below the second air inlet port 12. The second air inlet port 12 is formed on the bottom wall of the air inlet frame 10 and is covered with a lower filter 2. The lower filter 2 is detachably arranged at the air inlet frame 10 and can be installed in the casing assembly 1 through the disassembly port 11 or removed from the casing assembly 1 through the disassembly port 11.

[0061] The rear shell component 6 includes a side panel 61 and a back panel 62 . There are two side panels 61 . The two side panels 61 are respectively connected to the left and right ends of the back panel 62 and to the front side of the back panel 62 . The air outlet frame 511 and the air inlet frame 10 are both connected to the front ends of the two side panels 61 .

[0062] The heat exchange and air supply assembly is arranged in the casing assembly 1, and the heat exchange and air supply assembly includes a duct component 3 and a heat exchanger component 4. The heat exchanger component 4 is arranged in the casing assembly 1 and is located above the duct component 3. The duct component 3 includes an duct volute 32 and a wind wheel 33 arranged in the duct volute 32. The duct volute 32 is formed with an air flow inlet 31 and an air flow outlet. The air flow inlet 31 is formed on the front side of the duct volute 32 and is located on the rear side of the air inlet cavity. The air flow outlet is formed on the rear side of the heat exchanger component 4.

[0063] When the air conditioner is working, the wind wheel 33 drives the air flow to enter through the first air inlet 15 and the second air inlet 12 respectively. After the air flow of the first air inlet 15 and the second air inlet 12 is filtered by the filter and the lower filter 2 respectively, the filtered air flow flows into the air duct volute 32 through the air flow inlet 31, and the wind wheel 33 drives the air flow to flow to the heat exchanger component 4 through the air flow outlet. The air flow exchanges heat when flowing through the heat exchanger component 4. After the heat exchange, the air flow through the air outlet frame 511 is blown into the room through the air outlet 512 to heat up or cool down the room.

[0064] According to the air conditioner of the embodiment of the utility model, the lower filter 2 can be disassembled and assembled by providing a disassembly opening 11 for disassembling and assembling the lower filter 2 on the casing assembly 1; and, by providing the disassembly opening 11 on the side wall of the casing assembly 1, the lower filter 2 can be taken out from the side of the casing assembly 1 or installed into the casing assembly 1, which can reduce the difficulty of disassembling and assembling the lower filter 2 and make the disassembly and assembly operation of the lower filter 2 more convenient.

[0065] Reference Fig.14 and Fig.15 According to some embodiments of the utility model, a disassembly handle 21 is provided at one end of the lower filter 2 adjacent to the disassembly opening 11. When disassembling the lower filter 2, the user can hold the disassembly handle 21 by hand, which is convenient for the user to apply force; and by providing the disassembly handle 21 at one end adjacent to the disassembly opening 11, it is convenient to grasp the disassembly handle 21 at a position adjacent to the disassembly opening 11, thereby facilitating the disassembly or installation of the lower filter 2.

[0066] Reference Figure 8 and Fig.10 According to some embodiments of the present invention, there are two lower filters 2 arranged on the left and right sides, and the left and right walls of the housing assembly 1 are both formed with disassembly openings 11, and the two lower filters 2 are respectively installed into the housing assembly 1 or taken out from the housing assembly 1 through the two disassembly openings 11. The two lower filters 2 are respectively installed into the housing assembly 1 or taken out from the housing assembly 1 through the two disassembly openings 11, which can prevent the lower filter 2 from getting stuck during the assembly process due to being too long, and can make the assembly of the lower filter 2 smoother.

[0067] For example, when installing the lower filter 2 on the left side of the casing assembly 1, the lower filter 2 can be installed into or removed from the casing assembly 1 through the disassembly and assembly port 11 on the left side of the casing assembly 1; for another example, when installing the lower filter 2 on the right side of the casing assembly 1, the lower filter 2 can be installed into or removed from the casing assembly 1 through the disassembly and assembly port 11 on the right side of the casing assembly 1.

[0068] Reference Figure 8 and Fig.10According to some embodiments of the utility model, the housing assembly 1 includes an air inlet frame 10, the bottom wall of the air inlet frame 10 is formed with a second air inlet 12, a pressing plate 13 is provided on the bottom wall of the air inlet frame 10, at least part of the lower filter 2 is sandwiched between the bottom wall of the air inlet frame 10 and the pressing plate 13, and the pressing plate 13 can be pressed tightly on the top of the lower filter 2 to prevent the lower filter 2 from moving upward. At least part of the lower filter 2 is sandwiched between the bottom wall of the air inlet frame 10 and the pressing plate 13, and the lower filter 2 can be limited by the provided pressing plate 13, which can enhance the stability and reliability of the cooperation between the lower filter 2 and the bottom wall of the air inlet frame 10.

[0069] For example, when the air flow through the second air inlet 12 is too large, at least a portion of the lower filter 2 is clamped between the bottom wall of the air inlet frame 10 and the pressure plate 13, which can enhance the stability between the lower filter 2 and the bottom wall of the air inlet frame 10 and reduce the possibility of displacement of the lower filter 2 due to excessive air flow.

[0070] Among them, at least part of the lower filter 2 is clamped between the bottom wall of the air inlet frame 10 and the pressure plate 13, which may include the following situations: for example, the entire lower filter 2 may be clamped between the bottom wall of the air inlet frame 10 and the pressure plate 13; for another example, part of the lower filter 2 may be clamped between the bottom wall of the air inlet frame 10 and the pressure plate 13, and the other part of the lower filter 2 is not clamped between the bottom wall of the air inlet frame 10 and the pressure plate 13.

[0071] Reference Fig.12 According to some embodiments of the present invention, the pressure plate 13 includes a pressure plate body 131 and a guide portion 132. The guide portion 132 is connected to one side of the pressure plate body 131 adjacent to the corresponding disassembly and assembly port 11. In the direction from the pressure plate body 131 to the guide portion 132, the distance between the guide portion 132 and the bottom wall of the air inlet frame 10 gradually increases. The guide portion 132 has a guiding and auxiliary effect on the installation of the lower filter 2. During the assembly of the lower filter 2, the lower filter 2 extends into the air inlet frame 10 through the disassembly and assembly port 11, and the lower filter 2 is inserted into the gap 18 between the pressure plate 13 and the bottom wall of the air inlet frame 10 through the gap 18 between the pressure plate 13 and the bottom wall of the air inlet frame 10. After the lower filter 2 is inserted into the gap 18 between the pressure plate 13 and the bottom wall of the air inlet frame 10, the pressure plate body 131 is pressed tightly on the top of the lower filter 2 and contacts with the lower filter 2, and there can be a certain gap 18 between the guide portion 132 and the lower filter 2.

[0072] During the installation of the lower filter 2, the guiding effect of the guide portion 132 can make the assembly operation of the lower filter 2 faster and more convenient, and can also reduce the degree of damage caused by the collision between the end faces of the lower filter 2 and the pressure plate 13 during the assembly process, thereby reducing the friction and wear of the lower filter 2 during assembly.

[0073] Reference Fig.12According to some embodiments of the present invention, at least a portion of the bottom wall of the air inlet frame 10 constitutes a guide wall 101, which has a guiding and auxiliary effect on the installation of the lower filter screen 2, so that the assembly position of the lower filter screen 2 can be accurate; and, in the insertion direction of the lower filter screen 2, the guide wall 101 extends obliquely downward, utilizing the downward characteristic of the gravity of the lower filter screen 2. In the insertion direction of the lower filter screen 2, under the guiding effect of the guide wall 101 obliquely downward, the lower filter screen 2 can be assembled between the pressure plate 13 and the bottom wall of the air inlet frame 10 with a relatively small force, which can prevent the lower filter screen 2 from getting stuck during the assembly process, making the assembly of the lower filter screen 2 smoother.

[0074] Furthermore, during the process of disassembling and removing the lower filter 2, in the removal direction of the lower filter 2, the upward inclined guiding action of the guide wall 101 can also facilitate the user to apply force to the lower filter 2 to smoothly remove the lower filter 2.

[0075] Among them, at least part of the bottom wall of the air inlet frame 10 constitutes the guide wall 101, which may include the following situations: for example, the entire air inlet frame 10 may constitute the guide wall 101; for another example, a part of the air inlet frame 10 may constitute the guide wall 101, and the other part may not constitute the guide wall 101.

[0076] Reference Fig.14 According to some embodiments of the utility model, the bottom wall of the air inlet frame 10 is provided with a limiting structure 102, which is located on one side of the pressure plate 13 adjacent to the corresponding disassembly opening 11, and one end of the lower filter 2 adjacent to the corresponding disassembly opening 11 cooperates with the limiting structure 102 to limit the lower filter 2. The limiting structure 102 can limit the one end of the lower filter 2 adjacent to the corresponding disassembly opening 11, thereby enhancing the stability of the cooperation between the lower filter 2 and the bottom wall of the air inlet frame 10.

[0077] For example, the installation process of the lower filter 2 can be: insert the lower filter 2 from the disassembly and assembly port 11 and push the lower filter 2 in the direction close to the bottom wall of the air inlet frame 10, so that at least part of the lower filter 2 is clamped between the bottom wall of the air inlet frame 10 and the pressure plate 13, and one end of the lower filter 2 adjacent to the disassembly and assembly port 11 is inserted into the limiting structure 102, thereby completing the installation process of the lower filter 2.

[0078] The disassembly process of the lower filter 2 can be as follows: pull one end of the lower filter 2 adjacent to the corresponding disassembly port 11 from the disassembly port 11 along the direction away from the bottom wall of the air inlet frame 10, so that the one end of the lower filter 2 adjacent to the corresponding disassembly port 11 is pulled out from the limiting structure 102, and pull the lower filter 2 along the direction away from the bottom wall of the air inlet frame 10, so that the entire lower filter 2 is pulled out from the disassembly port 11, thereby completing the disassembly process of the lower filter 2.

[0079] Reference Fig.14According to some embodiments of the present utility model, the limiting structure 102 includes a first limiting portion 103 and a second limiting portion 104, the first limiting portion 103 is arranged on the bottom wall of the air inlet frame 10, the second limiting portion 104 is connected to the side of the first limiting portion 103 away from the corresponding disassembly opening 11 and extends toward the direction adjacent to the pressing plate 13, and one end of the lower filter 2 adjacent to the disassembly opening 11 is accommodated in the limiting groove 105 defined by the first limiting portion 103 and the second limiting portion 104. The limiting groove 105 can limit one end of the lower filter 2 adjacent to the disassembly opening 11, thereby enhancing the stability of the fit between the lower filter 2 and the bottom wall of the air inlet frame 10.

[0080] For example, the installation process of the lower filter 2 can be: insert the lower filter 2 from the disassembly and assembly port 11 and push the lower filter 2 in the direction close to the bottom wall of the air inlet frame 10, so that at least part of the lower filter 2 is clamped between the bottom wall of the air inlet frame 10 and the pressure plate 13, and one end of the lower filter 2 adjacent to the disassembly and assembly port 11 is inserted into the limit groove 105, thereby completing the installation process of the lower filter 2.

[0081] The disassembly process of the lower filter 2 can be as follows: pull one end of the lower filter 2 adjacent to the corresponding disassembly port 11 from the disassembly port 11 along the direction away from the bottom wall of the air inlet frame 10, so that the one end of the lower filter 2 adjacent to the corresponding disassembly port 11 is pulled out from the limiting groove 105, and pull the lower filter 2 along the direction away from the bottom wall of the air inlet frame 10, so that the entire lower filter 2 is pulled out from the disassembly port 11, thereby completing the disassembly process of the lower filter 2.

[0082] Reference Fig.14 According to some embodiments of the present invention, the second limit portion 104 extends upwardly in a direction from the connection between the second limit portion 104 and the first limit portion 103 to the free end of the second limit portion 104. The second limit portion 104 extends upwardly in a direction in a direction in which a guiding auxiliary function is provided for the assembly of the lower filter 2. The disassembly and assembly handle 21 of the lower filter 2 can be inserted into or pulled out of the limit structure 102 with relatively small force, so that the disassembly or installation of the lower filter 2 is smooth; and the degree of damage to the end surface of the lower filter 2 and the limit structure 102 due to collision during the disassembly or installation process can be reduced.

[0083] Reference Fig.14 According to some embodiments of the utility model, a disassembly handle 21 is provided at one end of the lower filter 2 adjacent to the disassembly opening 11, and the disassembly handle 21 is located on a side of the second limit portion 104 adjacent to the pressure plate 13, and the disassembly handle 21 is higher than the second limit portion 104. When disassembling or installing the lower filter 2, the disassembly handle 21 is higher than the second limit portion 104, so that the user can grasp the disassembly handle 21 and apply force conveniently; and the user's hand can be prevented from being stuck in the limit groove 105, so that the user's hand can be prevented from being pinched.

[0084] For example, when installing the lower filter 2, hold the disassembly and assembly handle 21 to insert the lower filter 2 and push the lower filter 2 in the direction close to the bottom wall of the air inlet frame 10, so that at least part of the lower filter 2 is clamped between the bottom wall of the air inlet frame 10 and the pressure plate 13, and one end of the lower filter 2 adjacent to the disassembly and assembly port 11 is inserted into the limiting groove 105, completing the installation process of the lower filter 2. By making the disassembly and assembly handle 21 higher than the second limiting portion 104, the user's hand can be easily pulled out.

[0085] When removing the lower filter 2, since the disassembly handle 21 is higher than the second limit portion 104, the user can conveniently grasp the disassembly handle 21 and pull one end of the lower filter 2 adjacent to the corresponding disassembly port 11 in a direction away from the bottom wall of the air inlet frame 10, so that the one end of the lower filter 2 adjacent to the corresponding disassembly port 11 is pulled out from the limit groove 105, and the lower filter 2 is pulled in a direction away from the bottom wall of the air inlet frame 10, so that the entire lower filter 2 is pulled out from the disassembly port 11, thereby completing the disassembly process of the lower filter 2.

[0086] Reference Figure 8 and Fig.10 According to some embodiments of the present invention, there are two lower filters 2 arranged on the left and right sides, and the left and right walls of the housing assembly 1 are both formed with disassembly openings 11, and the two lower filters 2 are respectively installed into the housing assembly 1 or taken out from the housing assembly 1 through the two disassembly openings 11. The two lower filters 2 are respectively installed into the housing assembly 1 or taken out from the housing assembly 1 through the two disassembly openings 11, which can prevent the lower filter 2 from getting stuck during the assembly process due to being too long, and can make the assembly of the lower filter 2 smoother.

[0087] There are two pressing plates 13 arranged at intervals on the left and right, and a limiting rib plate 14 is provided on the bottom wall of the air inlet frame 10. The limiting rib plate 14 is located between the two pressing plates 13, and one end of the pressing plate 13 away from the corresponding disassembly opening 11 is fixed to the limiting rib plate 14. The limiting rib plate 14 can limit the end of the lower filter screen 2 away from the corresponding disassembly opening 11 to ensure that the assembly position of the lower filter screen 2 is accurate.

[0088] For example, when installing the lower filter 2 on the left side or the lower filter 2 on the right side, the lower filter 2 can be inserted from the disassembly and assembly port 11 on the left side and pushed in the direction close to the bottom wall of the air inlet frame 10, so that at least part of the lower filter 2 is clamped between the bottom wall of the air inlet frame 10 and the pressure plate 13, and the end of the lower filter 2 away from the disassembly and assembly port 11 on the left side is abutted against the limiting rib 14, thereby completing the installation process of the lower filter 2.

[0089] When removing the lower filter 2 on the left side or the lower filter 2 on the right side, the lower filter 2 can be pulled from the left disassembly port 11 in a direction away from the bottom wall of the air inlet frame 10, so that the end of the lower filter 2 away from the left disassembly port 11 is released from the abutment with the limiting rib 14, and the lower filter 2 can be continued to be pulled from the left disassembly port 11 in a direction away from the bottom wall of the air inlet frame 10, so that the entire lower filter 2 is pulled out from the left disassembly port 11, completing the disassembly process of the lower filter 2.

[0090] Reference Figure 8 and Fig.10 According to some embodiments of the utility model, a first air inlet 15 is formed on the side wall of the air inlet frame 10. By setting the first air inlet 15 on the side wall of the air inlet frame 10 and setting the second air inlet 12 on the bottom wall of the air inlet frame 10, air can be taken in from the bottom and side of the housing, which can not only increase the air inlet area, but also achieve air inlet from different sides of the housing, with a wider air inlet angle and air inlet range. A detachable outer air inlet grille 16 is provided at the first air inlet 15. The outer air inlet grille 16 has a certain coarse filtering effect on the airflow, and the outer air inlet grille 16 is set to be detachable, which is also convenient for the maintenance and cleaning of the outer air inlet grille 16.

[0091] Among them, at least a part of the lower area of ​​the first air inlet 15 constitutes the disassembly and assembly port 11, and at least a part of the first air inlet 15 can be used as the disassembly and assembly port 11, which can save the need to specially set up the disassembly and assembly port 11 in the casing assembly 1. From another perspective, it can also be said that the disassembly and assembly port 11 is used as a part of the first air inlet 15, which can increase the air inlet area of ​​the first air inlet 15.

[0092] For example, when installing the lower filter 2, the outer air inlet grille 16 is removed from the first air inlet 15, and the lower filter 2 can be installed between the bottom wall of the air inlet frame 10 and the pressure plate 13 from the disassembly and assembly port 11 to complete the installation process of the lower filter 2.

[0093] When removing the lower filter 2, the outer air inlet grille 16 is removed from the first air inlet 15, and the lower filter 2 can be pulled out from between the bottom wall of the air inlet frame 10 and the pressure plate 13 through the disassembly port 11 to complete the disassembly process of the lower filter 2.

[0094] Reference Figure 8 and Fig.12According to some embodiments of the utility model, an inner air inlet grille 17 extending in the up-down direction is provided in the air inlet frame 10. The inner air inlet grille 17 is arranged opposite to the first air inlet 15. The inner air inlet grille 17 can guide the airflow entering from the first air inlet 15 and can guide the airflow entering from the first air inlet 15 to the air duct component 3. There is a gap 18 between the bottom surface of the inner air inlet grille 17 and the bottom wall of the air inlet frame 10, and the gap 18 is used to avoid the lower filter 2. There is a certain gap 18 between the bottom surface of the inner air inlet grille 17 and the bottom wall of the air inlet frame 10, and the gap 18 is used to avoid the lower filter 2, which can avoid interference between the lower filter 2 and the inner air inlet grille 17, and make the lower filter 2 easy to disassemble and assemble.

[0095] Reference Fig.12 and Fig.14 According to some embodiments of the utility model, the lower end of the inner air inlet grille 17 is recessed in a direction away from the first air inlet 15 to form an avoidance space 171. The avoidance space 171 is used to avoid deformation of the lower filter 2 during the disassembly and assembly process, thereby avoiding interference between the lower filter 2 and the inner air inlet grille 17 during the disassembly and assembly of the lower filter 2, and facilitating the disassembly or installation of the lower filter 2.

[0096] For example, when removing or installing the lower filter 2, at least a portion of the lower filter 2 close to the first air inlet 15 will arch in a direction away from the bottom wall of the air inlet frame 10 and produce a certain deformation, so that the length of the lower filter 2 in the left-right direction will be shortened, which can facilitate the removal or installation of the lower filter 2.

[0097] By recessing the lower end of the inner air inlet grille 17 in a direction away from the first air inlet port 15 to form an escape space 171, it can be ensured that the arched and deformed portion of the lower filter 2 close to the first air inlet port 15 can be accommodated in the gap 18 between the inner air inlet grille 17 and the bottom wall of the air inlet frame 10, thereby facilitating the disassembly or installation of the lower filter 2.

[0098] Reference Fig.16 According to some embodiments of the present invention, the lower filter screen 2 includes a mesh 22 and a filter screen support 23 for fixing and supporting the mesh 22, and the filter screen support 23 and the mesh 22 are integrally formed. This can improve the overall structural strength of the lower filter screen 2, and save the assembly process between the filter screen support 23 and the mesh 22, thereby helping to improve the assembly efficiency of the lower filter screen 2.

[0099] Reference Fig.15 and Fig.16According to some embodiments of the present invention, the filter screen support 23 has a plurality of support openings 231, the mesh 22 covers the support openings 231, the inner sidewall of the support openings 231 is formed with a step structure 232, and the mesh 22 supports and is fixed to the step structure 232. The mesh 22 covers the support openings 231 and the inner sidewall of the support openings 231 is formed with a step structure 232, and the step structure 232 can provide certain support and protection for the mesh 22, thereby enhancing the overall structural strength of the lower filter screen 2 and extending the service life of the lower filter screen 2.

[0100] For example, the mesh 22 is injection molded on the filter bracket 23. Under the high temperature environment of injection molding, the mesh 22 is easily torn due to excessive stretching. A step structure 232 is formed through the inner wall of the bracket opening 231. The step structure 232 can provide certain support and protection for the mesh 22, which can reduce the possibility of the mesh 22 being torn due to excessive stretching, thereby enhancing the overall structural strength of the lower filter 2.
