[0034] In existing air conditioners, filters are usually installed on the outer surface of the air conditioner casing using fasteners such as screws or clips. This is not only inconvenient for quick installation and removal of the filter, but also the clips are prone to failure due to wear from repeated installation and removal when the filter is attached to the casing. Furthermore, the filter is also prone to damage because it is located outside the casing.

[0035] To solve this technical problem, this utility model proposes an air conditioner, which can be an air handling device such as a wall-mounted air conditioner, a floor-standing air conditioner, or a portable air conditioner.

[0036] Please see Figures 1 to 8 In one embodiment of this utility model, the air conditioner includes a panel 11 and a filter assembly 20. The panel 11 has an air vent 111 and a pull-out opening 112. The air vent 111 is provided with a grille 12. The filter assembly 20 can be pulled out of the pull-out opening 112. The filter assembly 20 includes a frame 21 and a filter screen disposed on the frame 21. The frame 21 is installed on the inner side of the panel 11 and is at least partially located in the pull-out opening 112. The filter screen covers the air vent 111. This arrangement can improve the ease of disassembly and assembly of the filter assembly 20 and extend the service life of the filter assembly 20.

[0037] In the technical solution of this utility model, the filter assembly 20 extends into or out of the air conditioner through the pull-out opening 112 on the panel 11, enabling quick assembly and disassembly of the filter assembly 20. When the filter assembly 20 is installed in place, the frame 21 of the filter assembly 20 is installed on the inner side of the panel 11, and at least part of the frame 21 is located at the pull-out opening 112. That is, by using part of the frame 21 to lock into the pull-out opening 112, the assembly of the filter assembly 20 on the panel 11 is completed. The panel 11 can also protect the filter assembly 20 from external damage. Furthermore, compared to the frame 21 engaging with the panel 11 through additional clips, this effectively reduces the possibility of connection failure due to wear after repeated assembly and disassembly, helps extend the service life of the filter assembly 20, improves the connection reliability between the filter assembly 20 and the panel 11, and helps improve the ease of assembly and disassembly of the filter assembly 20, making it convenient for users to clean the filter.

[0038] It should be noted that panel 11 can be configured as a front panel 11 or as... Figure 1 The rear panel 11 shown, when configured as a rear panel, has an air vent 111 that serves as an air inlet 111. This air vent 111 is also equipped with a grille 12 to allow airflow, assist in heat dissipation of the air conditioner, and protect the internal functional modules of the air conditioner, ensuring its normal operation. The pull-out opening 112 is adapted to the size of the filter assembly 20, ensuring that the filter assembly 20 can be smoothly pulled out of the pull-out opening 112, thereby improving the efficiency of filter assembly 20 installation and removal.

[0039] The connection methods between the grille 12 and the panel 11 include, but are not limited to, snap-fit ​​and integral molding. When the grille 12 is snapped onto the panel 11, a locking pin can be provided on the panel 11, and a locking groove can be provided on the grille 12. The grille 12 is fixed by the engagement of the locking pin and the locking groove, which facilitates the easy assembly and disassembly of the grille 12. When the grille 12 and the panel 11 are integrally molded, it helps to reduce the number of parts and assembly steps, reduce costs, improve the overall stability of the panel 11, and to a certain extent, make the surface of the panel 11 smoother, reduce seams and defects, and improve the aesthetics of the panel 11. The connection methods between the frame 21 and the filter include, but are not limited to, snap-fit ​​connection and adsorption connection. The filter covers the air vent 111 and can filter the air entering the air conditioner.

[0040] Please see Figure 4 , Figure 7 and Figure 8In an embodiment of this utility model, the frame 21 includes a closed plate 211 and a mesh frame 212 connected to each other. The mesh frame 212 is installed on the inner side of the panel 11, and the closed plate 211 closes the pull-out opening 112. The filter screen is disposed on the mesh frame 212. With this arrangement, the mesh frame 212 and the filter screen are disposed on the inner side of the panel 11, which can prevent external forces from directly damaging the mesh frame 212 and the filter screen, ensuring the filtration effect of the filter assembly 20. The closed plate 211 is designed in two ways: firstly, the size of the closed plate 211 matches the size of the pull-out opening 112 to close the pull-out opening 112 and reduce the possibility of foreign objects entering the air conditioner through the pull-out opening 112; secondly, the closed plate 211 can also serve as a handle for pulling out the filter assembly 20. Due to its larger size, it is convenient to pull out the filter assembly 20, thereby improving the ease of pulling out the filter assembly 20. The connection methods between the filter screen and the mesh frame 212 include, but are not limited to, integral molding, bonding, and snap-fit ​​connection; the connection methods between the closed plate 211 and the mesh frame 212 include, but are not limited to, integral molding and bonding.

[0041] Specifically, in the embodiments of this utility model, the mesh frame 212 is a flexible structure, and the filter screen can also be a flexible structure. Therefore, when the filter screen assembly 20 extends into the pull-out port 112, the mesh frame 212 and the filter screen can be bent by utilizing their soft and bendable flexible characteristics, so that the mesh frame 212 and the filter screen can be pulled along the inner surface of the panel 11, thereby speeding up the efficiency of the filter screen assembly. At the same time, it does not require excessive use of installation space inside the air conditioner during the assembly process, thus improving the ease of assembly of the filter screen assembly 20.

[0042] Please see Figures 3 to 4 , Figures 7 to 8 In an embodiment of this utility model, the frame 21 further includes a limiting plate 213. The closing plate 211 is connected to the mesh frame 212 through the limiting plate 213, and the closing plate 211 and the mesh frame 212 are respectively disposed on opposite sides of the limiting plate 213. The limiting plate 213 is limited and abuts against the inner wall of the pull-out opening 112. It can be understood that, in the direction from the inside to the outside of the air conditioner, the closing plate 211 and the mesh frame 212 are respectively laterally connected to both ends of the limiting plate 213. The free ends of the sealing plate 211 and the mesh frame 212 extend in opposite directions. Therefore, when the limiting plate 213 is in limiting contact with the inner wall of the pull-out opening 112, the mesh frame 212, together with the filter screen, is built into the inner side of the panel 11, and the filter screen can cover the air vent 111, ensuring that the filter screen blocks the air or foreign objects from entering the air conditioner through the air vent 111. At the same time, the sealing plate 211 closes the pull-out opening 112, reducing the possibility of foreign objects entering the air conditioner through the pull-out opening 112 and improving the safety of the air conditioner.

[0043] Furthermore, in the embodiments of this utility model, the outer surfaces of the sealing plate 211 and the panel 11 are flush. That is, during the process of assembling the filter assembly 20 to the panel 11, the outer surface of the sealing plate 211 is flush with the outer surface of the panel 11 to indicate to the user that the assembly of the filter assembly 20 is complete, which is clear and easy to understand. At the same time, it reduces the possibility of damage to the sealing plate 211 due to the protrusion of the pull-out opening 112, and extends the service life of the filter assembly 20.

[0044] Please see Figures 7 to 8 In an embodiment of this utility model, a handle 214 is provided on the side of the closed plate 211 away from the mesh frame 212. The handle 214 protrudes from the closed plate 211, which can improve the ease of pulling out the filter assembly 20 to a certain extent. It can be understood that when disassembling the filter assembly 20, by grasping the handle 214, the closed plate 211 is disengaged from the pull-out port 112. When the closed plate 211 of the filter assembly 20 is further pulled away from the pull-out port 112, the closed plate 211 can be grasped to make the filter assembly 20 be pulled out of the pull-out port 112 as a whole, thus completing the disassembly of the filter assembly 20.

[0045] The side of the closed plate 211 facing away from the handle 214 is provided with a reinforcing groove, which corresponds to the handle 214 and helps to improve the structural strength of the frame 21 at the closed plate 211, thereby reducing the impact of the force applied to the closed plate 211 on the structure of the closed plate 211.

[0046] Optionally, in an embodiment of this utility model, the inner side of the panel 11 is provided with a limiting groove 131 along the pulling direction to guide the pulling of the filter assembly 20. This can guide the mesh frame 212, reduce the possibility of jamming during the pulling process, improve the smoothness and efficiency of the pulling of the filter assembly 20, and thus ensure the quick disassembly and assembly and convenient cleaning of the filter assembly 20. At the same time, since the filter assembly 20 is always placed in the limiting groove 131 during the pulling process, the disassembly and assembly of the filter assembly 20 can be completed without a large space.

[0047] Specifically, in an embodiment of this utility model, a limiting protrusion 132 protrudes from the inner side of the panel 11. A limiting stop 133 is laterally connected to one end of the limiting protrusion 132 away from the panel 11. The limiting stop 133, the limiting protrusion 132, and the grille 12 together form the limiting groove 131. It can be understood that the limiting protrusion 132 can extend along the periphery of the air vent 111 and the pull-out opening 112. In this case, as... Figure 2As shown, the limiting protrusion 132 can be annular, and both the air vent 111 and the pull-out opening 112 are located inside the limiting protrusion 132. The limiting block 133 is laterally connected to the end of the limiting protrusion 132 away from the panel 11, so that the limiting block 133, the limiting protrusion 132, and the grille 12 can surround and form a limiting groove 131. The limiting protrusion 132 has two first protrusion segments extending along the pull-out direction and two second protrusion segments connecting the two first protrusion segments. When there are two limiting blocks 133, the two limiting blocks 133 are respectively connected to the two first protrusion segments, or as shown in the figure. Figure 2 As shown, the limiting block 133 is semi-circular and connected to the two first convex segments and a second convex segment. This arrangement allows the mesh frame 212 to always remain close to the inner surface of the panel 11. Combined with the flexibility of the mesh frame 212, it can be smoothly pulled out into the limiting groove 131. However, this design is not limited to this. In other embodiments, the limiting convex edge 132 only includes two spaced-apart first convex segments that extend along the pulling direction of the filter assembly 20. In this case, there are two limiting blocks 133, each connected to one of the two first convex segments.

[0048] Taking the pull-out opening 112 located above the air vent 111 as an example, when installing the filter assembly 20, as follows: Figures 5 to 6 The filter assembly 20, along with its mesh frame 212, is inserted into the pull-out opening 112. Because the limiting groove 131 is positioned around the pull-out opening 112 and the air vent 111, the mesh frame 212 enters the limiting groove 131 simultaneously with its insertion into the pull-out opening 112. Due to the flexible structure of the mesh frame 212, under the action of the limiting block 133, the mesh frame 212 bends and slides downwards along the limiting groove 131 until the filter covers the air vent 111. At this point, if... Figure 4 As shown, the limiting plate 213 is in limiting contact with the inner wall of the pull-out opening 112, and the outer surface of the closing plate 211 is flush with the outer surface of the panel 11. Thus, as... Figure 1 and Figure 3 As shown, the filter assembly 20 is installed on the panel 11.

[0049] When disassembling the filter assembly 20, grasp the handle 214 and apply an upward pulling force. The sealing plate 211, through the limiting plate 213, drives the mesh frame 212 to slide upward along the limiting groove 131 until the filter assembly 20 is completely separated from the panel 11, thus achieving the disassembly of the filter assembly 20 and facilitating cleaning of the filter assembly 20. However, this design is not limited to this. In other embodiments, the pull-out port 112 is located to the left, right, or below the air vent 111.

[0050] Optionally, in an embodiment of this utility model, the air conditioner includes an indoor unit and an outdoor unit, with the panel 11 and the filter assembly 20 both located in the indoor unit; the indoor unit and the outdoor unit are connected by a refrigerant hose assembly, and the refrigerant hose assembly is pre-filled with refrigerant; specifically, the air conditioner of this utility model can be a split-type air conditioner that is easy for users to install themselves, using a refrigerant hose assembly to connect the indoor heat exchanger of the indoor unit and the outdoor heat exchanger of the outdoor unit, and injecting refrigerant into the refrigerant circuit before the equipment leaves the factory; thus, when users install the equipment themselves, they only need to fix the indoor unit and the outdoor unit separately, without needing to assemble refrigerant pipes and add refrigerant, thereby reducing the installation difficulty and enabling users to install themselves. However, this design is not limited to this; in other embodiments, the air conditioner of this utility model can also be a common split-type air conditioner.

[0051] Optionally, in an embodiment of this utility model, the compressor of the air conditioner is located in the indoor unit, which can reduce the weight of the outdoor unit and facilitate the installation of the outdoor unit; correspondingly, the compressor is also equipped with a noise reduction structure to ensure low-noise operation of the indoor unit.

[0052] Optionally, in an embodiment of this utility model, the bottom of the indoor unit is provided with casters to facilitate the movement and transport of the indoor unit; correspondingly, the indoor unit is provided with a locking structure to constrain the rotation of the casters, ensuring stable operation of the indoor unit.

[0053] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
