[0091] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0092] The following is for reference. Figures 1-44 This invention describes an air conditioner according to an embodiment of the present invention.

[0093] An air conditioner 100 according to an embodiment of the present utility model includes: a housing 1, a filter component 2, and a heat exchange and air supply assembly 3.

[0094] Reference Figure 1 and Figure 2 The housing 1 extends vertically and is provided with an air inlet 101 and an air outlet 102. The rear end of the housing 1 is provided with an air inlet 101, a mounting cavity 103 and a pull-out port 1031. The mounting cavity 103 and the air inlet 101 are arranged opposite each other in the front-to-back direction. The pull-out port 1031 is located on the left and / or right side of the mounting cavity 103 and extends vertically, or the pull-out port 1031 is located on the upper and / or lower side of the mounting cavity 103 and extends horizontally. The filter screen component 2 can be pulled out and installed in the mounting cavity 103 through the pull-out port 1031 and covers the air inlet 101. The heat exchange and air supply assembly 3 is provided in the housing 1.

[0095] For example, the pull-out opening 1031 can be located on the left side of the mounting cavity 103; for another example, the pull-out opening 1031 can be located on the right side of the mounting cavity 103; for yet another example, the pull-out opening 1031 can be located on both the left and right sides of the mounting cavity 103.

[0096] In related technologies, for an air conditioner 100 with a rectangular cross-section and an air inlet 101 located on the rear side, the filter component 2 can typically only be pulled out or inserted from a specific side of the air conditioner 100 (e.g., only from the left side of the air conditioner 100). When a user places the air conditioner 100 in a corner of the room, if the side of the filter component 2 with the pull-out opening faces the wall, the filter component 2 will interfere with the wall during the user's process of pulling out the filter component 2.

[0097] Reference Figures 1-38 By positioning the pull-out port 1031 on the left and / or right side of the mounting cavity 103 and extending it vertically, the filter element 2 can be pulled out or installed into the mounting cavity 103 from the pull-out port 1031 via the left or right side. For different air conditioner 100 installation scenarios, it is possible to choose to disassemble or install from the left or right side, avoiding interference between the filter element 2 and the wall 4 during the disassembly and installation process, and thus matching different scenarios.

[0098] In some embodiments, refer to Figure 3 The air conditioner 100 is a cabinet-type air conditioner. The pull-out opening 1031 is located on the left and right sides of the mounting cavity 103 and extends vertically. The air conditioner 100 is placed on the side of the room closest to the wall 4, with the wall 4 at the back of the air conditioner 100. When installing the filter component 2 of the air conditioner 100, the user can choose to insert the filter component 2 into the mounting cavity 103 through the pull-out opening 1031 on the left or right side of the air conditioner 100, depending on the placement of other furniture. When disassembling the filter component 2 of the air conditioner 100, it can be removed from the pull-out opening 1031 on the left or right side of the air conditioner 100. This avoids interference between the filter and other furniture during the disassembly or installation process and reduces the difficulty for relevant personnel in disassembling and installing the filter.

[0099] In some embodiments, refer to Figure 4 The air conditioner 100 is a cabinet-type air conditioner. The pull-out opening 1031 is located on the left and right sides of the installation cavity 103 and extends vertically. The air conditioner 100 is placed in a corner of the user's wall, with the left and rear sides of the air conditioner 100 being walls 4. When installing the filter component 2 of the air conditioner 100, the filter component 2 can be inserted into the installation cavity 103 through the pull-out opening 1031 on the right side of the air conditioner 100. When disassembling the filter component 2 of the air conditioner 100, it can be removed from the pull-out opening 1031 on the right side of the air conditioner 100. This avoids interference between the filter and the wall 4 during the disassembly or installation process of the air conditioner 100, reducing the difficulty for relevant personnel in disassembling and installing the filter.

[0100] In some embodiments, refer to Figure 5The air conditioner 100 is a cabinet-type air conditioner. The pull-out opening 1031 is located on the left and right sides of the installation cavity 103 and extends vertically. The air conditioner 100 is placed in a corner of the user's wall, with the right and rear sides of the air conditioner 100 being walls 4. When installing the filter component 2 of the air conditioner 100, the filter component 2 can be inserted into the installation cavity 103 through the pull-out opening 1031 on the right side of the air conditioner 100. When disassembling the filter component 2 of the air conditioner 100, it can be removed from the pull-out opening 1031 on the right side of the air conditioner 100. This avoids interference between the filter and the wall 4 during the disassembly or installation process of the air conditioner 100, reducing the difficulty for relevant personnel in disassembling and installing the filter.

[0101] Reference Figures 39-44 By positioning the pull-out port 1031 on the upper and / or lower side of the mounting cavity 103 and extending in the left-right direction, the filter element 2 can be pulled out or inserted into the mounting cavity 103 from the pull-out port 1031 through the upper or lower side. The pull-out path of the filter element 2 does not pass through the left and right sides of the air conditioner 100. Regardless of whether the air conditioner 100 is placed on the left or right side of the wall 4, interference between the filter element 2 and the wall 4 during the disassembly and assembly process can be avoided, reducing the difficulty for relevant personnel to disassemble and assemble the filter.

[0102] In some embodiments, refer to Figure 39 The air conditioner 100 is a rectangular cabinet air conditioner. The pull-out port 1031 is located on the upper side of the mounting cavity 103 and extends in the left-right direction. The air conditioner 100 is placed in the corner of the user's wall. When installing the filter component 2 of the air conditioner 100, the filter component 2 can be inserted into the mounting cavity 103 from top to bottom through the pull-out port 1031 on the upper side. When disassembling the filter component 2 of the air conditioner 100, the filter component 2 can be taken out through the pull-out port 1031 on the upper side of the air conditioner 100. Since the pull-out path of the filter component 2 does not pass through the left and right sides of the air conditioner 100, this can avoid interference between the filter and the wall 4 during the disassembly or installation process, reducing the difficulty for relevant personnel to disassemble and install the filter.

[0103] According to the embodiment of the present invention, the air conditioner 100, by positioning the pull-out port 1031 on the left and / or right side of the mounting cavity 103 and extending it vertically, allows the filter element 2 to be pulled out or installed in the mounting cavity 103 from the left or right side. For different air conditioner 100 installation scenarios, disassembly and assembly can be performed from the left or right side, avoiding interference between the filter element 2 and the wall 4 during the disassembly and assembly process, thus matching different scenarios. Furthermore, by positioning the pull-out port 1031 on the upper and / or lower side of the mounting cavity 103 and extending it horizontally, the filter element 2 can be pulled out or installed in the mounting cavity 103 from the upper or lower side. The pull-out path of the filter element 2 does not pass through the left and right sides of the air conditioner 100, avoiding interference between the filter element 2 and the wall 4 during the disassembly and assembly process, and reducing the difficulty for relevant personnel in disassembling and assembling the filter.

[0104] Reference Figure 14 and Figure 15 According to some embodiments of the present invention, the pull-out opening 1031 is located on the left and / or right side of the mounting cavity 103. The left and / or right ends of the mounting cavity 103 respectively form guide channels 1032. The inner wall of the guide channel 1032 forms a first guide surface 1033. The first guide surface 1033 extends to the pull-out opening 1031. The first guide surface 1033 extends forward in a left-right direction and in a direction close to the corresponding pull-out opening 1031.

[0105] For example, the pull-out opening 1031 is located on the left and right sides of the mounting cavity 103, and the left and right ends of the mounting cavity 103 respectively form guide channels 1032.

[0106] For example, the guide surface at the left end of the mounting cavity 103 extends to the left to the pull-out opening 1031 on the left side, and the guide surface at the right end of the mounting cavity 103 extends to the right to the pull-out opening 1031 on the right side.

[0107] By extending the first guide surface 1033 to the pull-out opening 1031, and by extending the first guide surface 1033 forward at an angle in the left-right direction and in the direction close to the corresponding pull-out opening 1031, the first guide surface 1033 can guide the filter screen component 2, allowing the filter screen component 2 to be inserted into the installation cavity 103 from the pull-out opening 1031 at an angle or to be pulled out from the installation cavity 103 from the pull-out opening 1031 at an angle. This can more effectively prevent the filter screen component 2 from interfering with the wall 4 during the disassembly and assembly process, reducing the difficulty for relevant personnel to disassemble and assemble the filter screen. Furthermore, this allows the air conditioner 100 to be compatible with installation scenarios where it is placed at an angle in the corner, preventing the filter screen component 2 from interfering with the left and right rear walls 4 of the air conditioner 100 during the extraction process.

[0108] In some embodiments, refer to Figure 6 The air conditioner 100 is a cabinet-type air conditioner with a rectangular cross-section. Pull-out openings 1031 are located on the left and right sides of the mounting cavity 103 and extend vertically. A first guide surface 1033 is formed on the inner wall of the guide channel 1032, extending to the pull-out opening 1031. The first guide surface 1033 extends forward at an angle in the left-right direction, closer to the corresponding pull-out opening 1031. The air conditioner 100 is placed diagonally in the corner of the user's wall, and walls 4 are provided on the left and right rear sides of the air conditioner 100. When installing the filter component 2 of the air conditioner 100, the filter component 2 can be inserted into the installation cavity 103 from the left front under the guidance of the first guide surface 103 through the pull-out port 1031 on the left side, or from the right front under the guidance of the first guide surface 1031 through the pull-out port 1031 on the right side. When disassembling the filter component 2 of the air conditioner 100, the filter component 2 can be taken out from the left front under the guidance of the first guide surface 1031 through the pull-out port 1031 on the left side of the air conditioner 100, or from the right front under the guidance of the first guide surface 1033 through the pull-out port 1031 on the right side of the air conditioner 100. Since the pull-out path of the filter component 2 is diagonal, this can avoid interference between the filter component 2 of the air conditioner 100 and the wall 4 during disassembly or installation, reducing the difficulty for relevant personnel to disassemble and install the filter.

[0109] Reference Figure 15 According to some embodiments of the present invention, the first guide surface 1033 is an arc-shaped surface or a plane. By making the first guide surface 1033 an arc-shaped surface or a plane, the guiding effect of the first guide surface 1033 on the filter screen component 2 can be improved, making it easier for the filter screen component 2 to be pulled out of the mounting cavity 103 or installed into the mounting cavity 103 under the guidance of the first guide surface 1033.

[0110] Reference Figure 15 According to some embodiments of this utility model, the angle between the first guide surface 1033 and the left-right direction is α, and the value of α ranges from 30° to 75°. For example, the angle α between the first guide surface 1033 and the left-right direction can be 30°, 45°, 50°, 60°, 75°, etc. By making the angle α between the first guide surface 1033 and the left-right direction range from 30° to 75°, the guiding effect of the first guide surface on the filter screen component 2 in the oblique direction can be better, more effectively avoiding interference between the filter screen component 2 of the air conditioner 100 and the wall 4 during disassembly or installation, and also preventing the filter screen component 2 from being deformed and damaged due to excessive bending angle.

[0111] Reference Figures 14-15According to some embodiments of the present invention, the housing 1 includes a housing 10 and an air inlet grille 11. The housing 10 is provided with an air inlet 101 and an air outlet 102. The air inlet 101 is located on the rear side wall of the housing 10. The air inlet grille 11 is installed on the rear side of the housing 10 and together with the housing 10 defines at least a portion of the mounting cavity 103. By installing the air inlet grille 11 on the rear side of the housing 10 and together with the housing 10 defining at least a portion of the mounting cavity 103, the filter element 2 can be installed in the area between the air inlet grille 11 and the housing 10. When the air conditioner 100 is working, the heat exchange and air supply assembly 3 inside the air conditioner 100 drives the airflow to first pass through the air inlet grille 11, then through the filter element 2 for filtration, and finally enter the interior of the housing 10 through the air inlet 101 on the housing 10.

[0112] Reference Figure 15 According to some embodiments of this utility model, an installation cavity 103 and a pull-out port 1031 are defined between the air inlet grille 11 and the housing 10, and a first guide surface 1033 is formed on the rear side wall of the housing 10. By forming the first guide surface 1033 on the rear side wall of the housing 10, when the filter screen component 2 is installed into the installation cavity 103 or when the filter screen component 2 is pulled out of the installation cavity 103, the first guide surface 1033 can provide oblique guidance for the filter screen component 2, thereby preventing the filter screen component 2 of the air conditioner 100 from interfering with the wall 4 during disassembly or installation.

[0113] Reference Figure 15 , Figures 23-28 According to some embodiments of the present invention, the filter screen component 2 includes a filter screen body 21 and a filter screen handle 22. The filter screen handle 22 is connected to one side of the filter screen body 21 in the left-right direction. At least a portion of the filter screen handle 22 is located within the guide channel 1032. A first mating surface 221 is formed on the side of the filter screen handle 22 facing the first guide surface 1033. The first mating surface 221 extends forward at an angle in the left-right direction and near the pull-out opening 1031. By including the filter screen handle 22 in the filter screen component 2, personnel can pull the filter screen component 2 out of the mounting cavity 103 by grasping the filter screen handle 22, or insert the filter screen component 2 into the mounting cavity 103 by grasping the filter screen handle 22, making the installation and removal of the filter screen component 2 more convenient. By forming a first mating surface 221 on the side of the filter handle 22 facing the first guide surface 1033, and by making the first mating surface 221 extend forward in the left-right direction and in the direction close to the pull-out opening 1031, the first mating surface 221 and the first guide surface 1033 can better cooperate and jointly play an oblique guiding role for the filter component 2, so as to avoid interference between the filter component 2 of the air conditioner 100 and the wall 4 during disassembly or installation.

[0114] For example, the first mating surface 221 and the first guide surface 1033 abut against each other.

[0115] For example, when removing the filter element 2 from the mounting cavity 103, under the combined guidance of the first mating surface 221 and the first guide surface 1033, the filter element handle 22 moves obliquely forward along the direction of the first guide surface 1033, pulling the filter element body 21 obliquely forward. After the filter element handle 22 separates from the first guide surface 1033, the filter element body 21 abuts against the first guide surface 1033, and the first guide surface 1033 guides the filter element body 21, enabling it to move obliquely forward until it is removed from the mounting cavity 103.

[0116] For example, when installing the filter component 2 into the mounting cavity 103, the filter body 21 is first brought into contact with the first guide surface 1033. Under the guidance of the first guide surface 1033, the filter component 2 is moved obliquely to the rear of the air conditioner 100, so that the filter body 21 is inserted into the guide channel 1032. The filter component 2 is moved further, and the filter handle 22 contacts the first guide surface 1033. Under the guidance of the first guide surface 1033, the filter handle 22 moves obliquely backward along the direction of the extension of the first guide surface 1033 until the filter component 2 is installed into the mounting cavity 103.

[0117] Reference Figure 15 According to some embodiments of the present invention, the inner wall of the guide channel 1032 is further provided with a second guide surface 1034. The second guide surface 1034 is formed on the front side wall of the air inlet grille 11. The second guide surface 1034 includes a first guide portion 1035 and a second guide portion 1036. In the left-right direction, the first guide portion 1035 is connected to the side of the second guide portion 1036 near the pull-out port 1031. The first guide portion 1035 extends forward at an angle in the left-right direction and in the direction close to the corresponding pull-out port 1031. The second guide portion 1036 extends forward at an angle in the left-right direction and in the direction away from the corresponding pull-out port 1031. By providing a second guide surface 1034 on the inner wall of the guide channel 1032, and the second guide surface 1034 being formed on the front side wall of the air inlet grille 11, the second guide surface 1034 can provide oblique guidance for the filter screen component 2 when it is installed into the mounting cavity 103.

[0118] By including a first guide portion 1035 in the second guide surface 1034, the first guide portion 1035 extends forward at an angle in the left-right direction and in the direction close to the corresponding pull-out port 1031, so that when the end of the filter screen component 2 is inserted into the guide channel 1032, the first guide portion 1035 can guide the end of the filter screen component 2 to move obliquely backward into the mounting cavity 103.

[0119] By including a second guide portion 1036 in the second guide surface 1034, the second guide portion 1036 extends forward at an angle in the left-right direction and away from the corresponding pull-out opening 1031. The second guide portion 1036 can guide the end of the filter screen component 2 to bend, so that the filter screen component 2 can move from the guide channel 1032 into the mounting cavity 103, making the installation of the filter screen component 2 easier.

[0120] For example, when installing the filter screen component 2 into the mounting cavity 103, the end of the filter screen body 21 away from the filter screen handle 22 is inserted into the pull-out port 1031 in a backward direction. At this time, the first guide part 1035 abuts against the end of the filter screen body 21, guiding the filter screen component 2 to move in a backward direction. As the filter screen component 2 continues to move, the end of the filter screen body 21 disengages from the first guide part 1035 and abuts against the second guide part 1036. The second guide part 1036 guides the end of the filter screen body 21 to bend toward the mounting cavity 103, making it easier for the filter screen body 21 to extend into the mounting cavity 103 from the guide channel 1032, thus making the installation of the filter screen component 2 simpler.

[0121] Reference Figure 15 According to some embodiments of the present invention, the second guide surface 1034 includes an arc-shaped transition portion 1037, which connects the first guide portion 1035 and the second guide portion 1036. By including the arc-shaped transition portion 1037 in the second guide surface 1034, which connects the first guide portion 1035 and the second guide portion 1036, the second guide surface 1034 can guide the filter screen component 2 more fully, making it easier for the filter screen component 2 to abut against the first guide portion 1035 and the second guide portion 1036 sequentially under the guidance of the arc-shaped transition portion 1037. This allows the filter screen component 2 to bend and enter the mounting cavity 103, avoiding jamming during the movement of the filter screen component 2 and thus preventing installation difficulties.

[0122] Reference Figures 29-34 According to some embodiments of this utility model, the housing 1 further includes a guide member 12. The guide member 12 is disposed on the left and right sides of the air inlet grille 11 and located at the rear corner of the housing 1. The guide member 12 is an independently molded part and forms a guide channel 1032. By including the guide member 12 in the housing 1 and providing the guide channel 1032 in the guide member 12, the guide channel 1032 can guide the installation and removal of the filter element 2, so that the filter can be inserted into the mounting cavity 103 from the oblique front side to the oblique rear side or leave the mounting cavity 103 from the oblique front side, thus avoiding interference between the filter element 2 of the air conditioner 100 and the wall 4 during the removal or installation process.

[0123] Reference Figure 30According to some embodiments of this utility model, the guide member 12 is detachably connected to the air inlet grille 11. For example, the guide member 12 and the air inlet grille 11 are connected by fasteners. By making the guide member 12 detachably connected to the air inlet grille 11, the guide member 12 can be removed from the air inlet grille 11 during the transportation of the air conditioner 100 and stored separately. This avoids the guide member 12 from being deformed due to compression during the transportation of the air conditioner 100, which would cause it to fail to guide, and also prevents the filter screen component 2 from getting stuck in the guide channel 1032.

[0124] Reference Figures 3-6 According to some embodiments of the present invention, the pull-out port 1031 is located on the left and right sides of the mounting cavity 103. The filter screen component 2 includes a filter screen body 21 and a filter screen handle 22. The filter screen handle 22 is connected to one side of the filter screen body 21 in the left and right direction and blocks the pull-out port 1031. The housing 1 is provided with a first connecting structure 1101 and a second connecting structure 1102. The first connecting structure 1101 and the second connecting structure 1102 are respectively located on the left and right sides of the mounting cavity 103. The filter screen handle 22 can be detachably connected to both the first connecting structure 1101 and the second connecting structure 1102. The filter screen handle 22 can be selectively installed and fixed to the housing 1 through one of the first connecting structure 1101 and the second connecting structure 1102. By connecting the filter clip 22 to the filter body 21, and selectively mounting the filter clip 22 to the housing 1 via one of the first connecting structure 1101 and the second connecting structure 1102, the filter clip 22 can be installed on the left or right side of the mounting cavity 103. This allows the installation position of the filter clip 22 to be determined according to the wall 4 or furniture arrangement in the user's room, thus matching different installation scenarios and preventing the filter component 2 of the air conditioner 100 from interfering with the wall 4 during disassembly or installation.

[0125] For example, filter component 2 may include a filter body 21 and a filter handle 22.

[0126] For example, refer to Figure 5 The first connecting structure 1101 is located on the left side of the mounting cavity 103, and the second connecting structure 1102 is located on the right side of the mounting cavity 103. When the air conditioner 100 is placed in a corner of the wall, and the rear and right sides of the air conditioner 100 are close to the wall 4, the filter clip 22 can be connected and fixed to the first connecting structure 1101. In this way, the filter clip 22 can pull the filter body 21 to be installed or removed from the left side, so as to avoid interference between the filter part 2 of the air conditioner 100 and the wall 4 during the process of disassembly or installation.

[0127] For example, refer to Figure 4The first connecting structure 1101 is located on the left side of the mounting cavity 103, and the second connecting structure 1102 is located on the right side of the mounting cavity 103. When the air conditioner 100 is placed in a corner of the wall, and the rear and left sides of the air conditioner 100 are close to the wall 4, the filter clip 22 can be connected and fixed to the second connecting structure 1102. In this way, the filter clip 22 can pull the filter body 21 to be installed or removed from the right side, so as to avoid interference between the filter part 2 of the air conditioner 100 and the wall 4 during the process of disassembly or installation.

[0128] Reference Figure 27 According to some embodiments of this utility model, the center line located at the middle position of the filter handle 22 in the vertical direction is the first center line 222, and the filter handle 22 has an axisymmetric structure about the first center line 222. By making the filter handle 22 have an axisymmetric structure about the first center line 222, the filter handle 22 can be detachably connected to both the first connecting structure 1101 and the second connecting structure 1102.

[0129] For example, the line extending in the front-back direction is the first reference line. The filter handle 22 is connected to the first connecting structure 1101. The filter handle 22 can also be removed from the first connecting structure 1101 and rotated 180° along the first reference line to connect to the second connecting structure 1102.

[0130] Reference Figure 28 According to some embodiments of the present invention, the center line located at the middle position of the filter body 21 in the vertical direction is the second center line 211, and the filter body 21 has an axisymmetric structure about the second center line 211.

[0131] For example, the second centerline 211 coincides with the first centerline 222.

[0132] By making the filter body 21 axially symmetrical about the second center line 211, the filter body 21 can be installed on the filter handle 22 connected to the first connecting structure 1101 or on the filter handle 22 connected to the second connecting structure 1102.

[0133] For example, the line extending in the front-to-back direction is the first reference line, and the filter body 21 is mounted on the filter handle 22 connected to the first connecting structure 1101. The filter handle 22 can also be detached from the first connecting structure 1101, and the filter handle 22 and the filter body 21 can be rotated 180° together along the first reference line, so that the filter handle 22 can be connected to the second connecting structure 1102, and the filter component 2 can be installed into the mounting cavity 103 from the other side.

[0134] Reference Figure 15 and Figure 20According to some embodiments of this utility model, the filter clip 22 is snap-fitted to both the first connecting structure 1101 and the second connecting structure 1102. By snap-fitting the filter clip 22 to both the first connecting structure 1101 and the second connecting structure 1102, the connection between the filter clip 22 and the first and second snap-fit ​​structures is made more complete, preventing the filter clip 22 from falling off the first or second snap-fit ​​structure and causing the filter to fall out of the mounting cavity 103, thus rendering the filter ineffective. Furthermore, it makes the disassembly and installation of the filter clip 22 more convenient, reducing the difficulty of disassembling and assembling the filter clip 22.

[0135] Reference Figures 21-27 According to some embodiments of this utility model, the center line located at the middle position of the filter handle 22 in the vertical direction is the first center line 222. The filter handle 22 includes a handle body 223 and a plurality of first pins 224 and a plurality of first buckles 225 disposed on the handle body 223. The plurality of first pins 224 are distributed on the upper and lower sides of the first center line 222 and are arranged symmetrically about the first center line 222. The plurality of first buckles 225 are distributed on the upper and lower sides of the first center line 222 and are arranged symmetrically about the first center line 222. The first connecting structure 1101 and the second connecting structure 1102 both include a plurality of first slots 112 and a plurality of first engaging ribs 113. The first buckles 225 engage with the first engaging ribs 113, and the first pins 224 are inserted into the first slots 112.

[0136] Reference Figure 20 and Figure 27 By engaging the first buckle 225 with the first snap-fit ​​rib 113, the filter clip 22 can be detachably snapped onto the first connecting structure 1101 or the second connecting structure 1102. This ensures a more secure connection between the filter clip 22 and the first or second snap-fit ​​structure, preventing the filter clip 22 from detaching from the first or second snap-fit ​​structure and causing the filter to fall out of the mounting cavity 103, thus rendering the filter ineffective. Furthermore, this makes the disassembly and installation of the filter clip 22 more convenient, reducing the difficulty of disassembling and assembling the filter clip 22.

[0137] Reference Figure 22 and Figure 27 By inserting the first pin 224 into the first slot 112, the first or second snap-fit ​​structure can position the filter handle 22 in the vertical direction, preventing the filter handle 22 from sliding in the vertical direction and causing the filter component 2 to move up and down, thus rendering the filter ineffective.

[0138] Reference Figure 27 and Figure 28By symmetrically arranging multiple first pins 224 about the first center line 222 and multiple first latches 225 about the first center line 222, the first connecting structure 1101 and the second connecting structure 1102 can be symmetrically arranged, and the filter handle 22 can be detachably connected to both the first connecting structure 1101 and the second connecting structure 1102. For example, if the line extending in the front-back direction is the first reference line, the filter handle 22 can be connected to the first connecting structure 1101, and the filter handle 22 can also be detached from the first connecting structure 1101 and rotated 180° along the first reference line to connect to the second connecting structure 1102.

[0139] Reference Figures 19-22 According to some embodiments of this utility model, the opening of the first slot 112 located on the left side of the mounting cavity 103 faces left, and the opening of the first slot 112 located on the right side of the mounting cavity 103 faces right. In the left-right direction, the buckle of the first latch 225 is located on the side of the first latching rib 113 opposite to the corresponding pull-out opening 1031. By making the opening of the first slot 112 located on the left side of the mounting cavity 103 face left, and the opening of the first slot 112 located on the right side of the mounting cavity 103 face right, when the filter clip 22 is inserted into the pull-out opening 1031 from left to right, the first pin 224 is inserted into the first slot 112 with the opening facing left as the filter clip 22 moves; when the filter clip 22 is inserted into the pull-out opening 1031 from right to left, the first pin 224 is inserted into the first slot 112 with the opening facing right as the filter clip 22 moves.

[0140] By positioning the buckle portion of the first buckle 225 on the side of the first snap-fit ​​rib 113 that is away from the corresponding pull-out opening 1031 in the left-right direction, the first snap-fit ​​rib 113 can limit the buckle portion of the first buckle 225 in the left-right direction, preventing the first buckle 225 from moving towards the pull-out opening 1031 and causing the filter screen component 2 to fall out of the mounting cavity 103.

[0141] Reference Figures 26-27 According to some embodiments of this utility model, at least one side of the handle body 223 in the front-rear direction is provided with a limiting rib 226, and the limiting rib 226 abuts against the inner wall of the mounting cavity 103. By providing a limiting rib 226 on at least one side of the handle body 223 in the front-rear direction, and having the limiting rib 226 abut against the inner wall of the mounting cavity 103, the filter handle 22 can contact the inner wall of the mounting cavity 103 through the limiting rib 226, reducing the contact area between the handle body 223 and the mounting cavity 103, reducing the force required to remove the handle body 223 from the pull-out port 1031, and reducing the difficulty of removing the handle body 223.

[0142] For example, two first limiting ribs 2261 are provided on the front side of the handle body 223. The two first limiting ribs 2261 are located on both sides of the handle body 223 along the vertical direction, and the first limiting ribs 2261 abut against the shell 10.

[0143] For example, a second limiting rib 2262 is provided on the rear side of the handle body 223. Multiple second limiting ribs 2262 are arranged at intervals in the vertical direction, and the second limiting ribs 2262 abut against the air inlet grille 11.

[0144] Reference Figure 19 According to some embodiments of the present invention, the housing 1 includes a housing 10 and an air inlet grille 11. The housing 10 is provided with an air inlet 101 and an air outlet 102. The air inlet 101 is located on the rear side wall of the housing 10. The air inlet grille 11 is installed on the rear side of the housing 10 and together with the housing 10 defines at least a portion of the mounting cavity 103. The first connecting structure 1101 and the second connecting structure 1102 are respectively provided at the left and right ends of the air inlet grille 11. By connecting the filter clip 22 to the filter body 21, and with the first connecting structure 1101 and the second connecting structure 1102 respectively located at the left and right ends of the air inlet grille 11, the filter clip 22 can be selectively installed and fixed to the housing 1 via one of the first connecting structure 1101 and the second connecting structure 1102. This allows the installation position of the filter clip 22 to be determined according to the wall 4 or furniture arrangement in the user's room, so that the filter component 2 can be disassembled via the left pull-out port 1031 or the right pull-out port 1031, which can match different installation scenarios and avoid interference between the filter component 2 of the air conditioner 100 and the wall 4 during disassembly or installation.

[0145] For example, refer to Figures 35-38 The mounting cavity 103 is also provided with a support rib 104, which is formed on the rear side of the housing 10 and extends in the left-right direction. The support rib 104 abuts against the filter screen component 2 in the vertical direction. The support rib 104 can support the filter screen component 2 upward, and can also allow the filter screen component 2 to slide into or out of the mounting cavity 103 along the extending direction of the support rib 104.

[0146] Reference Figure 24 According to some embodiments of this utility model, the filter screen handle 22 is detachably connected to the filter screen body 21. By making the filter screen handle 22 and the filter screen body 21 detachably connected, relevant personnel can remove the filter screen body 21 from the filter screen handle 22 for cleaning, thus achieving a more thorough cleaning of the filter screen body 21.

[0147] Reference Figure 39According to some embodiments of this utility model, the filter handle 22 is integrally formed with the filter body 21. By making the filter handle 22 integrally formed with the filter body 21, the number of overall parts of the air conditioner 100 can be reduced, and the assembly difficulty of the air conditioner 100 can be reduced.

[0148] Reference Figures 23-28 According to some embodiments of the present invention, the filter screen handle 22 includes a handle body 223 and a plurality of second buckles 228 disposed on the handle body 223. The handle body 223 is provided with an insertion groove 227, and the second buckles 228 are disposed on the side wall of the insertion groove 227. One end of the filter screen body 21 forms an insertion part 212, and the insertion part 212 is provided with a second snap-fit ​​rib 213. The insertion part 212 is inserted into the insertion groove 227, and the second buckles 228 are engaged with the second snap-fit ​​rib 213. By inserting the plug part 212 into the plug groove 227, and engaging the second buckle 228 with the second snap-fit ​​rib 213, the connection between the filter handle 22 and the filter body 21 can be made more complete. The second buckle 228 is positioned to limit the second snap-fit ​​rib 213 in the left and right directions, preventing the filter handle 22 from becoming disconnected from the filter body 21 during the process of pulling the filter handle 22, thus preventing the filter from being pulled out of the mounting cavity 103.

[0149] For example, when connecting the filter body 21 to the filter handle 22, first pre-align the insertion part 212 of the filter body 21 with the insertion groove 227, move the filter body 21 towards the filter handle 22, so that the end of the insertion part 212 is inserted into the insertion groove 227, continue to move the filter body 21 until the second snap-fit ​​rib 213 abuts against the second snap 228, the insertion part 212 is inserted into the insertion groove 227, and the filter body 21 is connected to the filter handle 22.

[0150] For example, refer to Figure 25 The insertion part 212 is also provided with a third limiting groove 214. The opening of the third limiting groove 214 is set towards the filter handle 22 in the left and right direction. The bottom wall of the insertion groove 227 is provided with a third limiting protrusion 229. The third limiting protrusion 229 extends in the left and right direction and is inserted into the third limiting groove 214.

[0151] Reference Figures 3-6According to some embodiments of the present invention, it also includes a decorative handle 23. The decorative handle 23 is detachably connected to both the first connecting structure 1101 and the second connecting structure 1102. One of the decorative handle 23 and the filter handle 22 is connected to the first connecting structure 1101 and blocks one of the pull-out openings 1031. The other of the decorative handle 23 and the filter handle 22 is connected to the second connecting structure 1102 and blocks the other pull-out opening 1031. By connecting one of the decorative handle 23 and the filter handle 22 to the first connecting structure 1101 and blocking one of the pull-out openings 1031, and connecting the other of the decorative handle 23 and the filter handle 22 to the second connecting structure 1102 and blocking the other pull-out opening 1031, the decorative handle 23 and the filter handle 22 can block the two pull-out openings 1031 respectively. This prevents the airflow from entering the air inlet 101 from the front side of the filter body 21 when the air conditioner 100 is working, thus avoiding the airflow from being filtered by the filter body 21 and improving the sealing performance. It can also cover the pull-out openings 1031, making the air conditioner 100 look more aesthetically pleasing.

[0152] For example, the filter component 2 includes a filter body 21, a filter latch 22, and a decorative latch 23. The filter latch 22 and the decorative latch 23 are fixedly connected to the first connecting structure 1101 and the second connecting structure 1102, respectively. The filter latch 22 is detachably connected to the filter body 21. In this way, the filter body 21 can be installed on the filter latch 22 or the decorative latch 23 connected to the first connecting structure 1101, or it can be installed on the filter latch 22 or the decorative latch 23 connected to the second connecting structure 1102. This allows the filter component 2 to be removed through the left pull-out port 1031 or the right pull-out port 1031, which can match different installation scenarios and avoid interference between the filter component 2 of the air conditioner 100 and the wall 4 during the removal or installation process.

[0153] According to some embodiments of this utility model, the decorative handle 23 is identical to the filter screen handle 22. By making the decorative handle 23 identical to the filter screen handle 22, the decorative handle 23 can be connected to either the first connecting structure 1101 or the second connecting structure 1102, and the filter screen handle 22 can be connected to either the first connecting structure 1101 or the second connecting structure 1102. When changing the disassembly / assembly direction of the filter body 21, it is only necessary to swap the positions of the decorative handle 23 and the filter screen handle 22 in the left-right direction, without needing to disassemble or connect the filter screen handle 22 to the filter body 21, thus simplifying the installation steps.

[0154] For example, filter screen component 2 includes a filter screen body 21, a filter screen handle 22 and a decorative handle 23, with the filter screen body 21 and the filter screen handle 22 integrally formed.
