Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a chassis component and an air conditioner. Background Art

[0002] When the air conditioner circulates indoor air, the internal fan easily allows fine dust to adhere to the condenser, and then the fine dust is discharged along with the condensed water in the condenser. Such condensed water is often not clean enough to be directly used for indoor humidification and other recycling purposes, which also limits the feasibility of its environmentally friendly discharge through atomization devices.

[0003] In the related art, by adding a filter device to the chassis assembly of the air conditioner, fine dust in the air can be intercepted and removed to ensure the purity of condensed water. However, after long-term use, the filter device will accumulate too much fine dust and reduce the filtering effect, so regular maintenance and cleaning are required. Therefore, the installation method of the filter device determines its maintenance convenience. Utility Model Content

[0049] Reference below Figure 1 - Figure 7 The chassis assembly 10 according to the embodiment of the first aspect of the utility model is described. It should be noted that in the embodiment of the present application, the chassis assembly 10 can be used in the air conditioner 100, but is not limited thereto. For example, the chassis assembly 10 can also be used in other devices that may generate condensed water. In the following description of the present application, the chassis assembly 10 is used in the air conditioner 100 as an example for explanation.

[0050] like Figure 1 As shown, the chassis assembly 10 according to the embodiment of the utility model includes: a chassis 1 and a filter device 2.

[0051] A water holding chamber 13 is formed on the bottom plate 1, and the top of the water holding chamber 13 is open. The function of the water holding chamber 13 is to directly or indirectly collect condensed water, improve the collection efficiency, and reduce the splashing and leakage of condensed water.

[0052] Exemplarily, the water chamber 13 is located at a specific position of the chassis 1, and the condensed water directly drips into the water chamber 13. Alternatively, a slope or a guide groove is provided on the chassis 1, so that the condensed water can naturally flow into the water chamber 13 along the slope or the guide groove. Alternatively, the condensed water flows into the water chamber 13 through a pipe.

[0053] Optionally, the water chamber 13 and the chassis 1 are formed as an integrally processed part, which can ensure the stability and reliability of the water chamber 13 on the chassis 1 and shorten the assembly time.

[0054] Of course, the present invention is not limited to this. A water box can be further processed on the basis of the processing of the chassis 1, and a water chamber 13 is formed on the water box. A positioning structure suitable for installing the water box is provided on the chassis 1. This arrangement is conducive to the separate maintenance and cleaning of the water box. It can be understood that whether it is processed and formed at one time or separately, as long as the water chamber 13 is provided on the chassis 1.

[0055] Combination Figure 1 The filter device 2 is detachably mounted on the chassis 1 along the up and down directions through the snap structure 3. The water inlet 221 of the filter device 2 is connected to the water holding chamber 13, and the water outlet 2311 of the filter device 2 is suitable for connecting with a pumping device (not shown).

[0056] Firstly, by providing the filtering device 2, the condensed water can be filtered, which is helpful for subsequent reuse and facilitates a certain protection of subsequent components such as a pumping device.

[0057] Secondly, the connection mode of the buckle structure 3 makes the installation and removal of the filter device 2 simple and quick, and is convenient for users to maintain and clean. At the same time, the buckle structure 3 can also ensure the stability of the filter device 2 during operation or movement, and improve the reliability of the use of the filter device 2.

[0058] In addition, disassembly and installation along the up and down directions can utilize the open top space of the water chamber 13 and the longitudinal space inside the air conditioner 100. During installation, the user only needs to snap the filter device 2 downward 33 to the corresponding position of the chassis 1 to fix it. When maintenance or cleaning is required, the user can pull out the filter device 2 upward without occupying too much lateral space. This design is convenient for the user's operation. At the same time, since the lateral space required for the disassembly and assembly of the filter device 2 is small, a certain layout space can be freed up for other components of the air conditioner 100, ensuring that the internal layout of the air conditioner 100 is more reasonable.

[0059] Moreover, by combining the pumping device and the chassis assembly 10 with the filtering device 2, the condensed water can be effectively collected, filtered and reused. For example, the condensed water generated during the operation of the air conditioner 100 is collected in the water storage chamber 13 of the chassis assembly 10, and then filtered by the filtering device 2 to remove impurities and particulate matter therein, thereby improving the cleanliness of the condensed water. The filtered clean water is then sucked in through the inlet of the pumping device and can be delivered to different application scenarios according to specific needs. For example, if the chassis assembly 10 is arranged indoors, the pumping device can pump the condensed water to the outdoor environment, or consume it in the form of an atomizing pump arranged outdoors.

[0060] In some embodiments, Figure 2-Figure 4 As shown, the buckle structure 3 includes: a buckle 33 and an elastic clip 34. Through the cooperation of the buckle 33 and the elastic clip 34, a stable connection between the filter device 2 and the chassis 1 is achieved. The elastic clip 34 is formed with a clip groove 342 with an opening 341 facing upward or downward, and the buckle 33 is suitable for being clamped in the clip groove 342 through the opening 341. When the buckle 33 is fully inserted into the clip groove 342, the elastic action of the elastic clip 34 causes it to tightly hold the buckle 33, thereby achieving a stable connection between the filter device 2 and the chassis 1.

[0061] For example, the filter device 2 is provided with an elastic clip 34, the elastic clip 34 is formed with a clip groove 342 with an opening 341 facing downward, and the chassis 1 is provided with a buckle 33. During installation, the filter device 2 drives the elastic clip 34 to move downward, so that the buckle 33 enters the clip groove 342 downward, thereby achieving a stable connection between the filter device 2 and the chassis 1; when disassembling, the filter device 2 is moved upward to separate the elastic clip 34 from the buckle 33.

[0062] For another example, the filter device 2 is provided with a buckle 33, and the chassis 1 is provided with an elastic clip 34, and the elastic clip 34 is formed with a clip groove 342 with an opening 341 facing upward. When the filter device 2 needs to be installed, the user only needs to align the buckle 33 of the filter device 2 with the elastic clip 34 on the chassis 1, and then press the filter device 2 downward; during the pressing process, the buckle 33 on the filter device 2 will naturally align and snap into the opening 341 of the elastic clip 34, and then the buckle 33 will enter and be fixed in the clip groove 342; similarly, when disassembling, the flow device 2 is moved upward to separate the buckle 33 from the elastic clip 33.

[0063] Both of the above two settings can achieve the snap-fit ​​effect between the chassis 1 and the filter device 2. In the following description of this application, the filter device 2 is provided with a buckle 33 and the chassis 1 is provided with an elastic clip 34 as an example for explanation, which will not be repeated below.

[0064] In some optional embodiments, the number of buckles 33 provided on the filter device 2 can be one or more, and the number of elastic clips 34 provided on the chassis 1 can be equal or unequal. When the number of buckles 33 is multiple, multiple buckles 33 are arranged in the transverse direction to ensure that the filter device 2 can be evenly stressed when installed or removed in the up and down directions, thereby maintaining a stable connection. When installing the filter device 2, the user only needs to align the buckle 33 on the filter device 2 with the elastic clip 34 on the chassis 1, and gently press the filter device 2 downward. As the filter device 2 descends, multiple buckles 33 will enter the openings 341 of the corresponding elastic clips 34, and finally be fixed in the clip groove 342. Since multiple buckles 33 act at the same time, it is more stable after installation.

[0065] In some Figure 3 In the illustrated embodiment, at least one of the two opposite groove walls of the clamping groove 342 has a first guide surface 343 at the position of the opening 341, and the first guide surface 343 is inclined so that the width of the opening 341 gradually decreases toward the center of the clamping groove 342. In this way, the buckle 33 on the filter device 2 can slide into the clamping groove 342 more smoothly along the first guide surface 343. Due to the inclined characteristics of the first guide surface 343, the buckle 33 will be gradually guided to the correct position when entering the clamping groove 342, reducing the difficulty of assembly caused by inaccurate alignment. In addition, the design of the first guide surface 343 can also reduce the force that the user needs to apply during the assembly process, and improve the comfort and efficiency of assembly. The user only needs to align the filter device 2 with the clamping groove 342 on the chassis 1 and gently push it downward, and the buckle 33 will naturally slide into the groove along the first guide surface 343 to achieve a stable connection.

[0066] In other embodiments, at least one of the two side surfaces of the buckle 33 that are opposite to each other has a second guide surface 334 at its free end, and the second guide surface 334 is inclined so that the width of the buckle 33 gradually increases toward the center of the buckle 33. Due to the existence of the second guide surface 334, when the buckle 33 approaches the opening 341 of the clamping groove 342, the width of its free end is equal to or slightly smaller than the width of the opening 341 of the clamping groove 342, thereby reducing the difficulty of assembly. At the same time, the inclined design of the second guide surface 334 plays a guiding role, so that the buckle 33 can slide into the clamping groove 342 more accurately, reducing the error in the assembly process. In addition, the design of the second guide surface 334 can also enhance the connection stability between the buckle 33 and the clamping groove 342.

[0067] In order to improve the clamping effect of the buckle structure 3, in some embodiments, at least one of the two opposite groove walls of the clamping groove 342 has a first guide surface 343 at the position of the opening 341, and the first guide surface 343 is inclined so that the width of the opening 341 gradually decreases toward the center of the clamping groove 342, and at least one of the two opposite surfaces of the buckle 33 has a second guide surface 334 at its free end, and the second guide surface 334 is inclined so that the width of the buckle 33 gradually increases toward the center of the buckle 33. With such a configuration, the buckle 33 can slide into the clamping groove 342 more smoothly along the first guide surface 343 during assembly, and the second guide surface 334 ensures that the buckle 33 gradually fits with the groove wall when entering the clamping groove 342, thereby significantly improving the clamping effect and assembly efficiency between the buckle 33 and the clamping groove 342.

[0068] In some embodiments, in combination Figure 3 , the minimum width W1 of the opening 341 is smaller than the maximum width W2 of the buckle 33. Then, when removing the filter device 2, a certain amount of force is required to remove the buckle 33 from the clamping groove 342, thereby preventing accidental loosening due to slight external force. This enhanced clamping mechanism ensures a stable connection between the filter device 2 and the chassis 1, and improves the reliability and safety of the air conditioner 100.

[0069] In some Figure 4 In the illustrated embodiment, the groove walls on both sides opposite to each other of the clamp groove 342 are respectively formed with first limiting surfaces 344, and the two first limiting surfaces 344 are obliquely extended to the minimum width position of the opening 341. The surfaces on both sides opposite to each other of the buckle 33 are respectively formed with second limiting surfaces 335, and the two second limiting surfaces 335 are obliquely extended to the maximum width position of the buckle 33. The first limiting surface 344 is suitable for abutting against the second limiting surface 335 to limit the buckle 33 from detaching from the elastic clamp 34.

[0070] When the buckle 33 is fully inserted into the clamping groove 342 , the abutment between the first limiting surface 344 and the second limiting surface 335 plays a limiting role, and the structure is simple and easy to implement.

[0071] For example, when the buckle 33 is fully inserted, the second limiting surfaces 335 on both sides thereof will fit tightly with the first limiting surfaces 344 of the clamping groove 342. This fit not only increases the contact area, thereby increasing the friction between the two, making it more difficult for the buckle 33 to slide out of the clamping groove 342. Of course, when the buckle 33 is fully inserted, the second limiting surfaces 335 on both sides can also be spaced from the first limiting surfaces 344 of the clamping groove 342, so that when the filter device 2 has a tendency to move toward the disassembly direction relative to the chassis 1, the first limiting member 344 can stop against the second limiting surface 335 to limit the above-mentioned movement tendency.

[0072] When the buckle 33 is affected by external force and tends to move upward, the second limiting surface 335 of the buckle 33 will bring an upward force to the first limiting surface 344. At the same time, the first limiting surface 344 of the clamping groove 342 will also generate a downward reaction force. This reaction force counteracts the upward external force, thereby helping to offset the upward external force and prevent the buckle 33 from loosening.

[0073] In some embodiments, in combination Figure 2 The elastic clip 34 is provided on the chassis 1, the opening 341 of the clip groove 342 is arranged upward, the buckle 33 is provided on the filter device 2 and cooperates with the elastic clip 34 in limiting position in the first direction, and the first direction can be a horizontal direction and is perpendicular to the up-down direction. This limiting cooperation ensures that the filter device 2 will not move randomly in the first direction, thereby improving the stability and reliability of its installation.

[0074] In some optional embodiments, such as Figure 3-Figure 5 As shown, the buckle structure 3 further includes a first stopper 31 . The first stopper 31 is disposed on the filter device 2 and connected to the buckle 33 . The first stopper 31 abuts against the upper end of the elastic clip 34 .

[0075] For example, in some embodiments, the bottom of the filter device 2 is spaced apart from the chassis 1, that is, the bottom of the filter device 2 is not supported by the chassis 1, and the first limiting member 31 abuts against the upper end of the elastic clip 34, thereby forming a stable support point in the up and down directions, ensuring that the filter device 2 receives additional support and limitation in the up and down directions, thereby preventing it from falling off or moving downward due to vibration, shaking or other factors.

[0076] For another example, in some embodiments, the bottom of the filter device 2 is in contact with the chassis 1, and the first stopper 31 can serve as an additional support point to ensure that the filter device 2 is firmly supported on the bottom surface to prevent it from shaking or tilting. Secondly, the first stopper 31 can also serve as a positioning device. When the first stopper 31 contacts the upper end of the elastic clip 34, it means that the filter device 2 has reached the correct installation position and is completely in contact with the chassis 1. At this time, the user can feel an obvious resistance. At the same time, the buckle 33 successfully cooperates with the elastic clip 34 to firmly install the filter device 2 on the chassis 1, and due to the existence of the first stopper 31, its position is further confirmed and fixed, which is convenient for user operation.

[0077] In some optional embodiments, such as Figure 3-Figure 5 As shown, the buckle structure 3 also includes a second stopper 32. The second stopper 32 is provided on the filter device 2 and is suitable for stopping at a side of the elastic clip 34 away from the water chamber 13 in a second direction, the second direction being perpendicular to the first direction and also perpendicular to the up-down direction.

[0078] Specifically, the second stopper 32 abuts against the side wall of the chassis 1 from the second direction, that is, in a direction parallel to the side wall of the chassis 1. When the filter device 2 is pressed down and installed on the chassis 1, the second stopper 32 will contact the side wall of the chassis 1, playing a role of pre-positioning. As the filter device 2 is further pressed down, the elastic clip 34 and the buckle 33 begin to cooperate, and a stable abutting relationship is formed between the stopper plate and the side wall of the chassis 1. The second stopper 32 is provided to further enhance the stability of the filter device 2 on the chassis 1.

[0079] In some optional embodiments, the buckle structure 3 includes a first stopper 31 and a second stopper 32. Through the joint action of the first stopper 31 and the second stopper 32, the filter device 2 is fixed in both the longitudinal and transverse directions. This can not only prevent the filter device 2 from shaking or shifting during use, but also extend the service life of the filter device 2 and ensure the normal operation of the air conditioner 100.

[0080] In some embodiments, the snap structure 3 includes a second limit member 32, the second limit member 32 and the filter device 2 define a matching groove b, the snap 33 is arranged in the matching groove b, and the side of the filter device 2 facing the second limit member 32 is suitable for abutting against the side wall of the water holding chamber 13.

[0081] Specifically, one side of the filter device 2 and the second stopper 32 form a stable positioning structure, which can effectively prevent the filter device 2 from shaking or shifting in the second direction, improve the position accuracy of the filter device 2, and thus maintain its filtering effect and performance.

[0082] In some embodiments, the filter device 2 is formed with at least one rib 21 suitable for abutting against the side wall of the water chamber 13 to reduce the contact area between the filter device 2 and the side wall of the water chamber 13 and reduce the resistance to disassembly and assembly.

[0083] Please refer to Figure 6 , Figure 6 Schematic diagram of the convex rib 21 of the filter device 2 of some embodiments of the present application. The convex rib 21 is a plurality of long ribs, and the plurality of long ribs are arranged at intervals in the longitudinal direction, wherein each long rib is extended along the first direction. By providing the convex rib 21, the contact area between the filter device 2 and the side wall surface of the water holding chamber 13 can be reduced, thereby reducing the difficulty of installation caused by friction and resistance, making the installation process smoother.

[0084] The solution of the present application is not limited thereto. In other embodiments of the present application, the convex rib 21 is a plurality of long ribs, and the plurality of long ribs are arranged at intervals along the first direction, wherein each long rib is arranged to extend in the longitudinal direction. Alternatively, the extending direction of the convex rib 21 may have a certain angle with the first direction, that is, it is arranged as an oblique rib or a cross rib, which can also reduce the contact area.

[0085] In some embodiments, please refer to Figure 2-Figure 4 The elastic clip 34 includes two elastic hooks 340 , and the two elastic hooks 340 are arranged at intervals to define a clip slot 342 . Each elastic hook 340 includes a first arm portion 3401 and a hook portion 3402 , and the hook portion 3402 is arranged at the free end of the first arm portion 3401 .

[0086] In the above technical solution, the first arm portion 3401, as the main body of the elastic hook 340, has a certain elasticity and toughness, can be deformed under the action of external force, and return to its original shape after the external force is removed. The hook portion 3402 is located at the free end of the first arm portion 3401 to ensure that it can firmly grasp the corresponding part of the filter device 2 to prevent it from slipping or shaking.

[0087] The hook portions 3402 of the two elastic hooks 340 are arranged opposite to each other. This relative arrangement design enables the two hook portions 3402 to contact two corresponding positions on the filter device 2 at the same time, thereby forming a stable fixed structure. When the filter device 2 is placed in the clamping groove 342, the two hook portions 3402 are squeezed at the same time to cause the elastic hook 340 to deform to adapt to the size and shape of the buckle 33, and return to its original shape after the filter device 2 is fully in place, and firmly lock it in the clamping groove 342.

[0088] In addition, the design of the elastic clip 34 also takes into account the requirements of installation and removal. The user only needs to gently push the filter device 2 into the clip slot 342, and the two hooks 3402 will automatically deform and grab the filter device 2. Similarly, when the filter device 2 needs to be removed, the user applies a certain pulling force to the filter device 2, and the two hooks 3402 will loosen, so that the filter device 2 can be smoothly removed from the clip slot 342.

[0089] Alternatively, if Figure 2-Figure 5 As shown, the elastic clip 34 further includes two reinforcing ribs, which are respectively arranged on opposite sides of the first arm portion 3401. The reinforcing ribs can strengthen the connection strength between the first arm portion 3401 and the chassis 1. Whether the elastic clip 34 is subjected to tension or pressure, the reinforcing ribs can effectively share the stress, making the elastic clip 34 more stable, thereby improving the stability and reliability of the buckle structure 3.

[0090] In some embodiments, Figure 5As shown, the two hooks 3402 are respectively formed with first grooves 345 on the opposite sides thereof. The design of the first grooves 345 makes it easier to control the forming of the first grooves 345 during the manufacturing process, which is beneficial to improving the thickness consistency of each part of the elastic hook 340, facilitating the realization of the equal thickness design of the elastic hook 340, and is beneficial to improving the manufacturing accuracy and efficiency of the mold. At the same time, the risk of deformation or damage caused by demoulding is reduced.

[0091] In some embodiments, Figure 5 As shown, a first guide surface 343 is formed on one side of the two hook portions 3402 opposite to each other. The first guide surface 343 is inclined so that the width of the opening 341 gradually decreases toward the center of the clamping groove 342. A portion of the first guide surface 343 is recessed to form a first groove 345, and the other portion of the first guide surface 343 can still play a role in guiding the installation.

[0092] In some embodiments, the buckle 33 includes a second arm 331 and two buckles 332, the two buckles 332 are respectively arranged on opposite sides of the second arm 331, and the two buckles 332 are formed with a second groove 333 on the opposite sides. The design of the second groove 333 is conducive to improving the thickness consistency of each part of the buckle 33 during the manufacturing process, facilitating the realization of the equal thickness design of the buckle 33, and is conducive to improving the manufacturing accuracy and efficiency of the mold. At the same time, the risk of deformation or damage caused by demoulding is reduced.

[0093] In some embodiments, Figure 5 As shown, the buckle 33 includes a second arm portion 331 and two buckles 332, the two buckles 332 are respectively arranged on opposite sides of the second arm portion 331, and a second groove 333 is formed on the side of the two buckles 332 that are opposite to each other, and at least one side of the two side surfaces of the buckle 33 that are opposite to each other has a second guide surface 334 at its free end, and the second guide surface 334 is inclined so that the width of the buckle 33 gradually increases toward the center of the buckle 33; wherein a portion of each second guide surface 334 is recessed toward the center of the buckle 33 to form a second groove 333, and the remaining portion of each second guide surface 334 can still play a role in guiding installation.

[0094] By providing the second groove 333 , the contact area between the buckle 33 and the clamping groove 342 can be reduced, so that the buckle 33 can encounter less resistance when sliding into the clamping groove 342 .

[0095] In other embodiments, Figure 5As shown, the buckle 33 includes a second arm 331 and two buckles 332, the two buckles 332 are respectively arranged on opposite sides of the second arm 331, and the two buckles 332 are formed with a second groove 333 on the opposite sides of each other; at the same time, the two first limiting surfaces 344 of the clamping groove 342 extend obliquely, and the two side surfaces of the buckle 33 opposite to each other are respectively formed with second limiting surfaces 335, and the two second limiting surfaces 335 extend obliquely to the maximum width position of the buckle 33, and the first limiting surface 344 is suitable for abutting and cooperating with the second limiting surface 335 to limit the buckle 33 from being separated from the elastic clamp 34. At this time, a part of the second limiting surface 335 is recessed toward the center of the buckle 33 to form the second groove 333, and the rest of the second limiting surface 335 can still play a limiting role, and can reduce a certain friction when the filter device 2 is disassembled.

[0096] In some embodiments, please refer to Figure 1 , Figure 7 A drain port 14 connected to the water storage chamber 13 is formed on the chassis 1, and a detachable plugging member is provided at the drain port 14. The drain port 14 is provided to provide an additional path for the discharge of condensed water, which not only increases the flexibility of the air conditioner 100, but also improves the efficiency of condensed water treatment.

[0097] Specifically, the plugging member is used to close the drain port 14 when necessary to prevent accidental leakage of condensed water or to maintain the sealing of the chassis 1 when the drain port 14 is not in use. For example, the plugging member is made of rubber, plastic or other sealing material to ensure a close fit with the drain port 14. When the plugging member is removed, the condensed water can be directly discharged into the external environment or other components through the drain port 14. This provides the air conditioner 100 with a simple and quick way to deal with condensed water, especially when the amount of condensed water generated is large or needs to be discharged frequently. In addition, the design of the drain port 14 can also be connected to other drainage systems (such as pipes, sinks, etc.) to achieve automatic discharge and collection of condensed water.

[0098] Although the drain port 14 provides a direct discharge path for the condensed water, in some cases, the user may still want to introduce the condensed water into the filter device 2 for treatment. To achieve this goal, in some optional embodiments, the blocking member can be a switching device or a valve to allow the user to select the discharge path of the condensed water as needed. When the switching device or the valve points to the filter device 2, the condensed water will be guided to the filter device 2 for filtration and treatment. When the switching device or the valve points to the drain port 14, the condensed water is directly discharged through the drain port 14.

[0099] In some embodiments, Figure 1 As shown, the chassis 1 includes a bottom plate 11 and a side plate 12 , the bottom plate 11 and the side plate 12 together form a water holding chamber 13 , and the buckle structure 3 is located at the upper end of the side plate 12 .

[0100] A portion of the filter device 2 is against the side plate 12, and the snap structure 3 is at the upper end of the side plate 12. Such a layout can ensure that the filter device 2 is stably placed in the water chamber 13 by fixing and supporting it in multiple directions, thereby effectively filtering the condensed water entering the water chamber 13, and it is convenient to make a portion of the filter device 2 located on the upper side of the side plate 12, so that the filter device 2 can be operated through the portion of the filter device 2 located on the upper side of the side plate 12 to realize its assembly and disassembly.

[0101] In some embodiments, Figure 6 As shown, the filter device 2 includes a filter portion 22 and a connecting portion 23, the water inlet 221 of the filter device 2 is formed on the filter portion 22, the connecting portion 23 includes a snap-on portion 232 and a joint portion 231, the water outlet 2311 of the filter device 2 is formed on the joint portion 231, the joint portion 231 is detachably connected to the filter portion 22, and the snap-on portion 232 cooperates with the chassis 1 through a snap-on structure 3.

[0102] The clamping portion 232 is disposed at one end of the connecting portion 23 and is used to clamp with the upper end of the side plate 12 of the chassis 1 , thereby achieving a stable connection between the filter device 2 and the chassis 1 .

[0103] The other end of the connecting portion 23, i.e., the end away from the clamping portion 232, is directly connected to the filter portion 22. This design allows the filter portion 22 to extend downward into the water chamber 13, ensuring that the water inlet 221 can be close to the bottom of the water chamber 13, thereby effectively sucking in and treating condensed water. The condensed water treated by the filter portion 22 is discharged through the joint portion 231 and enters the subsequent treatment or discharge system.

[0104] In some embodiments, the filter portion 22 includes a cylindrical filter support 222 , and a water inlet 221 of the filter device 2 is formed on a peripheral wall of the filter support 222 . The water inlet 221 can guide condensed water to enter the filter portion 22 .

[0105] Optionally, a first filter element (not shown) is provided at the water inlet 221 of the filter device 2. And / or, a second filter element (not shown) is provided in the barrel cavity of the filter bracket 222. The second filter element is located downstream of the first filter element and upstream of the water outlet 2311 of the joint portion 231, and the filter aperture of the second filter element is smaller than the filter aperture of the first filter element.

[0106] The first filter performs preliminary filtration of the condensate to remove larger particles and impurities such as dust, grit, etc. Its relatively large filter aperture ensures smooth water flow while capturing obvious contaminants.

[0107] The second filter element performs a finer filtration on the condensed water, removing those tiny particles and impurities that were not captured in the first filtration stage. Through this design, it can be ensured that the condensed water reaches a higher purity and quality after two-stage filtration.

[0108] In some optional embodiments, the drain port 14 is formed on the bottom plate 11 and / or the side plate 12 of the chassis 1. When the drain port 14 is formed on the side plate 12, it is located at the lower part of the water chamber 13, which is conducive to the condensed water flowing into the drain port 14 naturally.

[0109] According to the air conditioner 100 of the second embodiment of the utility model, Figure 7 As shown, it includes a pumping device and a chassis assembly 10 according to the first aspect of the utility model. The pumping device is installed on the chassis 1, and the inlet of the pumping device is connected to the water outlet 2311 of the filtering device 2.

[0110] It is understandable that the condensed water generated during the operation of the air conditioner 100 will be collected in the water storage chamber 13 of the chassis assembly 10, and then filtered by the filter device 2 to remove impurities and particulate matter therein, thereby improving the cleanliness of the condensed water. The filtered clean water is then sucked in through the inlet of the pumping device and then delivered to different application scenarios according to specific needs.

[0111] According to the air conditioner 100 of the embodiment of the present invention, by combining the pumping device and the chassis assembly 10 with the filtering device 2, the condensed water can be effectively collected, filtered and reused.

A portion of the filter device 2 extends to be opposite to the inspection port 201 so as to be suitable for being exposed through the inspection port 201. A detachable inspection panel is provided at the inspection port 201.

[0113] The filter device 2 can be disassembled and assembled through the inspection port 201, so that the user can remove the filter device 2 to replace the filter material or clean the filter cup, thereby avoiding the cumbersome process of disassembling the whole device for maintenance and greatly improving the convenience of maintenance.

[0114] Optionally, the access panel is connected to the housing 20 by screw connection, clamping connection, magnetic attraction, etc. Through simple operation, the access panel can be removed, thereby directly contacting the filter device 2.
