Therefore, they should not be construed as limitations on this invention.

[0045] In the description of this invention, "first feature" and "second feature" may include one or more of the features, "multiple" means two or more, "above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features being in contact through another feature between them, and "above," "over," and "on top" the second feature may include the first feature being directly above or diagonally above the second feature, or simply indicate that the first feature is at a higher horizontal level than the second feature.

[0046] The following description, with reference to the accompanying drawings, describes a filtration device 100 and an air conditioner 200 according to embodiments of the present invention.

[0047] like Figure 1 and Figure 2 As shown, the air conditioner 200 according to an embodiment of the present invention includes a filter device 100 according to an embodiment of the present invention. For example, the filter device 100 may be used in at least one of the indoor unit and the outdoor unit of the air conditioner 200.

[0048] In related technologies, some air conditioning devices with humidification functions can regulate the relative humidity of the room. However, such air conditioning devices generally have a complex structure and are difficult to operate by adding water. Users must add water on time during use, which increases the difficulty of use and reduces the user experience.

[0049] Therefore, in some embodiments of the present invention, the filter device 100 can be used to filter the condensate generated during the operation of the air conditioner 200 (such as removing dust and other impurities), so that the filtered condensate can be used for humidification, reducing the frequency of water addition by the user or eliminating the need for manual water addition by the user, thus improving the user experience.

[0050] In other embodiments of the invention, the filter device 100 can also be used to filter water manually added by the user to improve the water quality used for humidification and prevent scale or blockage in the humidification components. Specifically, the air conditioner 200 may have a water tank 210, and the filter device 100 may be connected to a water pipe in the water tank 210 to facilitate the filtration of the liquid in the water tank 210.

[0051] Of course, in addition to the humidification function, in some other embodiments, the filter device 100 can also be used for other functions, as long as it is used for filtering liquids.

[0052] Furthermore, the air conditioner 200 is generally installed in a location that is not easily touched by hands, and the filter 20 of the filter device 100 needs to be replaced after a period of use to ensure the filtration effect. Therefore, it is necessary to ensure that the filter 20 is fixed and stable when installed on the air conditioner 200 to avoid the risk of falling off, and to ensure that the disassembly process is simple and easy to operate.

[0053] Reference Figures 2-13 As shown, the filtering device 100 according to an embodiment of the present invention may include: a mounting base 10, a filter 20, and a locking member 30.

[0054] In some embodiments where the filter device 100 is installed in the air conditioner 200, such as Figure 1 and Figure 2 As shown, the air conditioner 200 may include a housing, and a mounting base 10 is mounted on the housing to facilitate the user's removal and installation of the filter 20 from the outside of the housing. For example, the mounting base 10 may be mounted on the face frame 220 of the housing, and the mounting base 10 is exposed after the housing panel is opened to facilitate the removal of the filter 20. Here, the mounting base 10 and the face frame 220 can be separate components connected together, or the mounting base 10 can be integrally formed on the face frame 220, all of which are within the protection scope of this invention.

[0055] Specifically, the mounting base 10 has a mounting cavity 101 in which the filter 20 is detachably mounted. The opening of the mounting cavity 101 can be configured as a disassembly port for removing and installing the filter 20, for example... Figure 1 and Figure 2 As shown, the opening of the mounting cavity 101 can face the front of the air conditioner 200. The user can push the filter 20 backward to install the filter 20 into the mounting cavity 101, and the user can pull the filter 20 forward to remove the filter 20 from the mounting cavity 101 for easy replacement.

[0056] Furthermore, the locking element 30 is mounted on the mounting base 10, and the locking element 30 is rotatable relative to the mounting base 10 between a locked position and an unlocked position.

[0057] like Figure 6 and Figure 7 As shown, when the locking member 30 is in the locked position, the locking member 30 can lock the filter 20 to fix the filter 20 in the mounting cavity 101. On the one hand, it prevents the filter 20 from falling off and damaging or injuring the user. On the other hand, it can ensure a reliable connection between the filter 20 and the liquid pipeline of the air conditioner 200, and improve the reliability and sealing of the filter.

[0058] like Figure 12 and Figure 13 As shown, when the locking member 30 is in the unlocked position, the locking member 30 can release the lock on the filter 20. At this time, the filter 20 can move relative to the mounting base 10 to be removed from the mounting cavity 101, which makes it convenient for the user to replace the filter 20 and ensure the filtration effect of the filter device 100.

[0059] The locking element 30 switches between locked and unlocked states by rotation, which is simple for users to operate. The locking structure of the filter 20 is also simple, which prevents the filter 20 from falling out and makes the disassembly and assembly of the filter 20 convenient, thus improving the user experience.

[0060] According to the embodiment of the present invention, the filter device 100 is installed in the mounting cavity 101 by means of the filter 20, and the locking member 30 switches between locking and unlocking states of the filter 20 by rotation, which ensures that the filter 20 is not easy to fall out after it is installed in place, thus improving the safety of use. Furthermore, the filter 20 can be disassembled by rotating the locking member 30 and pulling the filter 20, making it convenient to remove the filter 20 and easy for the user to operate.

[0061] Since the filter device 100 according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the air conditioner 200 according to the embodiment of the present invention has the filter 20 installed in the installation cavity 101, and the locking member 30 can switch between locking and unlocking the filter 20 by rotating, which ensures that the filter 20 is not easy to fall out after it is installed in place, thus improving the safety of use. Furthermore, the filter 20 can be disassembled by rotating the locking member 30 and pulling out the filter 20, making it convenient for the user to remove the filter 20 and operate it conveniently.

[0062] According to some embodiments of the present invention, such as Figures 6-8 and Figures 12-13 As shown, the locking member 30 is provided with a driving part 35, the filter 20 is provided with a driving engagement part 21, and the driving part 35 is located on the side of the driving engagement part 21 away from the opening of the mounting cavity 101. For example, in the embodiment where the opening of the mounting cavity 101 faces forward, the driving part 35 is located on the rear side of the driving engagement part 21.

[0063] Therefore, during the rotation of the locking member 30 from the locked position to the unlocked position, the driving part 35 can abut against the driving mating part 21 and push the driving mating part 21 toward the opening of the mounting cavity 101, thereby driving the filter 20 to move out of the mounting cavity 101. When the locking member 30 moves to the unlocked position, at least a part of the filter 20 can be located outside the mounting cavity 101, allowing the user to pull the filter 20 through the part located outside the mounting cavity 101 to disassemble the filter 20. In other words, by rotating the locking member 30, not only is unlocking achieved, but also the initial disassembly of the filter 20 is achieved, improving the convenience of user operation and facilitating one-handed operation for disassembling and assembling the filter 20.

[0064] In some embodiments, such as Figure 13 As shown, the two sides of the cavity opening of the mounting cavity 101 can also be deformed away from each other to form a handle groove 102. On the one hand, this can increase the space available to the user when the locking member 30 drives the filter 20 to move out. On the other hand, when the locking member 30 fails and cannot drive the filter 20 to move out, the user can clamp the filter 20 through the space in the handle groove 102 to pull the filter 20 out.

[0065] In some embodiments, such as Figures 6-8 As shown, during the installation of filter 20, when moving filter 20 from front to back into the mounting cavity 101, the drive mating part 21 can also abut against the drive part 35, driving the drive part 35 to move backward and causing the locking member 30 to rotate from the unlocked position to the locked position. Therefore, while inserting filter 20 into the mounting cavity 101, the filter 20 can be locked simultaneously, ensuring stable installation of the replaced filter 20 and further simplifying the user's operation.

[0066] The present invention does not impose special restrictions on the specific structure of the drive unit 35 and the drive mating unit 21. It only needs to meet the requirement that the two can cooperate to achieve transmission during the process of the locking member 30 rotating to unlock and during the process of the filter 20 moving into the mounting cavity 101.

[0067] For example, such as Figures 6-8As shown, the locking member 30 includes a connecting arm 31, one end of which is rotatably engaged with the cavity wall of the mounting cavity 101. The driving part 35 can be a protrusion on the outer peripheral surface of one end of the connecting arm 31, so that one end of the connecting arm 31 is formed as a cam structure. The driving engagement part 21 can be a protrusion on the surface of the filter 20, such as an upper protrusion on the upper surface of the filter 20. This causes the distance between the contact engagement position with the upper protrusion and the rotation axis to change during the rotation of the cam structure, thereby driving the upper protrusion to move. The other end of the connecting arm 31 can be provided as an operating end for the user or can be provided with a structure for user operation, so that the locking member 30 can be formed as a lever structure, making it easier for the user to rotate the locking member 30 to unlock and push the filter 20 out of the mounting cavity 101.

[0068] In some specific embodiments, such as Figure 8 As shown, the outer peripheral surfaces of the drive unit 35 and the drive mating part 21 can be smooth arc surfaces to reduce the frictional resistance between the drive unit 35 and the drive mating part 21 and reduce wear on both.

[0069] The locking structure of the locking member 30 according to some embodiments of the present invention is described below with reference to the accompanying drawings.

[0070] According to some embodiments of the present invention, such as Figures 3-8 As shown, the locking member 30 may include a connecting arm 31 and a locking part 32. One end of the connecting arm 31 is rotatably mounted to the cavity wall of the mounting cavity 101, and the locking part 32 is located at the other end of the connecting arm 31. When the locking member 30 is in the locked position, the locking part 32 stops against the side of the filter 20 facing the opening of the mounting cavity 101, for example... Figure 7 The front side is shown, thus preventing the filter 20 from falling out of the mounting cavity 101 and ensuring the stable installation of the filter 20.

[0071] In some embodiments, continue to refer to Figures 3-8 As shown, the locking part 32 can be a locking plate, and one side edge of the locking plate (such as...) Figure 7 The upper edge shown is connected to the connecting arm 31, and the other edge of the locking plate (as shown) is connected to the connecting arm 31. Figure 7 The other side (as shown) abuts against the filter 20. The mating structure of the connecting arm 31 and the locking plate is generally L-shaped.

[0072] On the one hand, it facilitates the rotatable connection between the connecting arm 31 and the cavity wall of the mounting cavity 101, and also facilitates the locking plate to abut against the filter 20 with a large contact area, ensuring the stability of the limit position. On the other hand, the direction of the stop force of the filter 20 on the locking plate is towards the outside of the mounting cavity 101, such as forward, so that the stop force of the filter 20 will not push the locking member 30 to rotate and unlock, ensuring the reliability of the lock. When unlocking is required, the user can unlock it by moving it upward (e.g., upward). Figure 10Push the locking plate (in the direction indicated by the middle arrow F) to rotate the connecting arm 31, making it easier for the user to unlock.

[0073] To improve the structural stability of the locking component 30, such as Figures 3-7 As shown, there can be two connecting arms 31, and the two connecting arms 31 are respectively installed on two opposing cavity walls of the mounting cavity 101, as shown. Figure 3 The left and right cavity walls are shown. Two connecting arms 31 are connected to both ends of the locking part 32 along its length, so that the locking member 30 is generally formed into a C-shaped structure. The locking part 32 can stop and limit the filter 20 over a wider range in the width direction of the filter 20, thus better preventing the filter 20 from falling out; and the connection between the locking member 30 and the mounting base 10 is more stable, and problems such as jamming are less likely to occur during rotation.

[0074] In some specific embodiments, such as Figures 3-6 As shown, the locking member 30 has a pivot 33. For example, the pivot 33 can be located at one end of the connecting arm 31. The pivot 33 is rotatably engaged with the cavity wall of the mounting cavity 101 to provide support for the locking member 30 to rotate between the unlocked position and the locked position. For example Figures 3-6 As shown, the two opposite side walls of the mounting cavity 101 can be provided with mounting grooves 103 respectively. The two connecting arms 31 of the locking member 30 are provided with rotating shafts 33 on their opposite sides. The rotating shafts 33 are inserted into the corresponding mounting grooves 103 to rotate within the mounting grooves 103.

[0075] Furthermore, the cavity wall of the mounting cavity 101 may be provided with a limiting protrusion 11, such as the bottom wall of the mounting groove 103 may be provided with a limiting protrusion 11. And the outer peripheral surface of the rotating shaft 33 may be provided with a mating protrusion 34.

[0076] When the locking element 30 is in the unlocked position, such as Figures 12-13 As shown, one side of the limiting protrusion 11 (such as...) Figure 12 and Figure 13 The upper side (as shown) can abut against the mating protrusion 34 to keep the locking member 30 in the unlocked position. Therefore, after the user removes the filter 20, the locking member 30 will not rotate back to the locked position under the limiting action of the limiting protrusion 11, so that when the user inserts the new filter 20 into the mounting cavity 101, the locking member 30 will not interfere with the filter 20, and the user can install the filter 20 with one hand. For example, when replacing the filter 20, other tools such as a ladder are usually needed. After climbing the ladder, one hand holds the ladder while the other hand removes or installs the filter 20, ensuring the safety of the operation.

[0077] When the locking element 30 is in the locked position, such as Figures 3-6 As shown, the other side of the limiting protrusion 11 (such as...) Figure 4The lower side (as shown) can abut against the mating protrusion 34 to keep the locking member 30 in the locked position. Thus, the locking member 30 can effectively limit the filter 20, preventing it from dislodging. When the filter 20 needs to be removed, the user can push the locking member 30 upwards, causing it to rotate upwards. Under external force, the mating protrusion will pass over the limiting protrusion 11 and move to one side of the limiting protrusion 11, completing the unlocking process.

[0078] According to some embodiments of the present invention, such as Figure 3 and Figure 6 As shown, the cavity wall of the mounting cavity 101 may be provided with a guide portion 12, which extends along the depth direction of the mounting cavity 101, that is, the guide portion 12 extends perpendicularly to the plane where the cavity opening of the mounting cavity 101 is located. The filter 20 is provided with a guide mating portion 22 for cooperating with the guide portion 12. One of the guide portion 12 and the guide mating portion 22 is a guide groove, and the other of the guide portion 12 and the guide mating portion 22 is a guide protrusion. During the process of installing the filter 20 into the mounting cavity 101, the guide protrusion can extend into the guide groove and move along the guide groove to guide the installation of the filter 20, ensuring that the filter 20 can be smoothly installed in the mounting cavity 101, thereby facilitating accurate water circuit connection.

[0079] According to some embodiments of the present invention, such as Figures 9-11 As shown, the filter 20 may have a first water pipe 23, which extends along the depth direction of the mounting cavity 101, that is, extends perpendicular to the plane where the opening of the mounting cavity 101 is located. In other words, the extension direction of the first water pipe 23 is the same as the movement direction of the filter 20 as it moves into the mounting cavity 101.

[0080] In some embodiments, such as Figure 12 As shown, at least a portion of the first water pipe 23 can protrude from the outer surface of the filter 20, so that the first water pipe 23 can serve as a guide fitting part 22 for guiding the disassembly and assembly of the filter 20, eliminating the need for a separate guide structure and simplifying the structure of the filter 20.

[0081] In some embodiments, such as Figures 9-11 As shown, a second water pipe 13 can be provided inside the mounting cavity 101, extending along the depth direction of the mounting cavity 101. Therefore, after the filter 20 is installed into the mounting cavity 101, the first water pipe 23 and the second water pipe 13 can be inserted and connected. The filter 20 is then moved along the depth direction of the mounting cavity 101 to be installed inside, simultaneously connecting the water circuit, simplifying the assembly process and making operation more convenient for the user.

[0082] In some embodiments, such as Figures 9-11As shown, the filter 20 may be provided with two first water pipes 23, and the corresponding mounting cavity 101 may be provided with two second water pipes 13. The two first water pipes 23 and the two second water pipes 13 are connected one-to-one to form two water paths, which are used as the inlet water path and outlet water path of the filter 20, respectively.

[0083] In embodiments including a water tank 210, at least one of the inlet water path and the outlet water path can be connected to the water tank 210. For example, if the inlet water path is connected to the water tank 210, the liquid stored in the water tank 210 can flow through the inlet water path to the filter 20 for filtration, and the filtered liquid can flow through the outlet water path to the humidification component for humidification; as another example, if the outlet water path is connected to the water tank 210, the condensate generated by the air conditioner 200 (such as the condensate in the chassis 230 of the air conditioner 200) can flow through the inlet water path to the filter 20 for filtration, and the filtered liquid can flow through the outlet water path to the water tank 210 for storage; as yet another example, the water tank 210 can have a first cavity and a second cavity, the liquid stored in the first cavity can flow through the inlet water path to the filter 20 for filtration, and the filtered liquid can flow through the outlet water path to the second cavity for storage.

[0084] In some embodiments of the present invention, such as Figures 10-11 and Figure 14 As shown, the first water pipe 23 and the second water pipe 13 can be press-fitted by the sealing element 40, which facilitates the disassembly and assembly of the first water pipe 23 and the second water pipe 13 while ensuring the sealing performance, preventing water leakage, and improving the anti-detachment effect of the filter 20.

[0085] In embodiments of the present invention, the specific structure of the seal 40 can be flexibly configured according to actual conditions.

[0086] For example, in some embodiments, such as Figure 10 and Figure 11 As shown, the sealing element 40 is a sealing ring 41. Taking the insertion of the first water pipe 23 into the second water pipe 13 as an example, the sealing ring 41 can be sleeved on the first water pipe 23 or embedded in the second water pipe 13 to prevent misalignment of the sealing ring 41 during assembly and disassembly. No additional fixing nuts or other fixing structures are required, simplifying the assembly structure. In some embodiments, the sealing element 40 can be an elastic element such as a rubber component or a silicone component.

[0087] In the embodiment where the sealing ring 41 is sleeved and installed on the first water pipe 23, the outer circumferential surface of the first water pipe 23 may also be provided with two rings of retaining ribs, located on both sides of the sealing ring 41 in the axial direction, so as to avoid misalignment of the sealing ring 41 and affect the sealing effect.

[0088] The diameter of the sealing ring 41 can be adjusted according to the dimensions of the first water pipe 23 and the second water pipe 13, but the following requirements must be met. Figure 11 As shown, the radial cross-sectional diameter of the sealing ring 41 is d, the outer diameter of the first water pipe 23 is D1, and the inner diameter of the second water pipe 13 is D2. Furthermore, d, D1, and D2 satisfy the following condition: 5% < (d - ((D2 - D1) / 2)) / d*100% < 50%. Within this dimensional range, the sealing ring 41 can be pressed tightly against the outer circumferential surface of the first water pipe 23 and the inner circumferential surface of the second water pipe 13, resulting in a good sealing effect.

[0089] In other embodiments, such as Figure 14 As shown, the sealing element 40 includes a sealing cylinder 42 disposed within the second water pipe 13. The outer circumferential surface of the sealing cylinder 42 can make sealing contact with the inner circumferential surface of the second water pipe 13. Furthermore, the inner diameter of the sealing cylinder 42 is D3, and the outer diameter of the first water pipe 23 is D4, where 0.5 < D3 / D4 < 1. Within the above dimensional range, the sealing cylinder 42 can press tightly against the outer circumferential surface of the first cylinder, and the mating area is large, resulting in a good sealing effect.

[0090] In embodiments where the sealing element 40 includes a sealing cylinder 42, the sealing cylinder 42 and the second water pipe 13 can be sealed together by means of interference fit, snap-fit, or fitting.

[0091] In some specific embodiments, such as Figure 14 As shown, the sealing element 40 may include a sealing cylinder 42 and an outer protrusion 43, the outer protrusion 43 being disposed on the outer peripheral surface of the sealing cylinder 42. The filter device 100 also includes a fixing element 50, the fixing element 50 including a fixing peripheral wall 51 and a fixing protrusion 52, the fixing protrusion 52 being disposed on the inner peripheral surface of the fixing peripheral wall 51. The sealing cylinder 42 extends into the second water pipe 13, and the outer protrusion 43 abuts against the axial end face of the second water pipe 13. The fixed peripheral wall 51 can be sleeved and installed on the second water pipe 13 to connect and fix it to the second water pipe 13, for example, by threaded connection, so that the fixed protrusion 52 can abut against the side of the outer protrusion 43 facing away from the second water pipe 13. The outer protrusion 43 is sandwiched between the end face of the second water pipe 13 and the fixed protrusion 52 to achieve fixation and sealing, and to prevent the seal 40 from being misaligned when the first water pipe 23 and the second water pipe 13 are inserted and removed. In addition, the fixing member 50 increases the force between the seal 40 and the second water pipe 13, thereby improving the sealing effect.
