[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", "front", "rear", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and a coordinate system XYZ is set herein, wherein the positive direction of the X-axis represents the right direction, the reverse direction of the X-axis represents the left direction, the positive direction of the Y-axis represents the front direction, the reverse direction of the Y-axis represents the rear direction, the positive direction of the Z-axis represents the top, and the reverse direction of the Z-axis represents the bottom; these are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0044] In the indoor unit of the air conditioner, the base is provided with an air duct. Since the heat exchanger is located above the air duct, a water channel structure is provided on each side of the base in the width direction of the air duct to support the heat exchanger and collect the condensed water of the heat exchanger. The water channel structure close to the air outlet of the air duct is the front water channel structure, and the water channel structure away from the air outlet of the air duct is the rear water channel structure. Usually, the water channel structure cooperates with the heat exchanger by setting a boss and supporting ribs in order to support the heat exchanger assembly. The condensed water of the heat exchanger flows into the water channel structure along the fins. After the air conditioner has been working for a long time, dust is easily collected in the water channel structure. However, due to the presence of supporting ribs and bosses in the water channel structure, it is often inconvenient to scrub and the cleaning is not thorough.

[0045] like Figure 1 As shown, an embodiment of the present invention provides a base assembly, including a filter screen assembly 2 and a base body 1, the base body 1 is provided with a water channel structure 13, the filter screen assembly 2 is detachably arranged at the water channel structure 13, and the filter screen assembly 2 is suitable for being arranged between the water channel structure 13 and the heat exchanger 3.

[0046] After adopting the base assembly of this embodiment, the filter mesh assembly 2 is arranged above the water channel structure 13, and after the assembly is completed, the filter mesh assembly 2 is located between the water channel structure 13 and the heat exchanger 3. When condensed water drips from the fins of the heat exchanger 3, the condensed water is filtered by the filter mesh assembly 2, which can make the dirt remain on the filter mesh assembly 2. The filtered condensed water enters the water channel structure 13, which greatly reduces the dirt blockage of the water channel structure 13.

[0047] Compared with the existing water channel structure 13, in this embodiment, the bottom wall of the water channel structure 13 eliminates the setting of the boss and the supporting ribs, which facilitates the cleaning of the water channel structure 13 after the filter assembly 2 is disassembled, thereby effectively preventing the water channel structure 13 from being dirty and blocked.

[0048] In this embodiment, the water channel structure 13 is the front water channel structure or the rear water channel structure of the base body 1, such as Figure 6 As shown, the water channel structure 13 is preferably a rear water channel structure. The filter assembly 2 can be located inside the water channel structure 13 or outside the water channel structure 13. In this embodiment, as shown in the figure, the filter assembly 2 is located outside the water channel structure, that is, the filter assembly 2 is located above the water channel structure 13. Therefore, the condensed water dripping from the fins of the heat exchanger 3 will not directly enter the water channel structure 13. The condensed water will first be filtered by the filter assembly 2, leaving the dirt on the filter assembly 2, and then enter the rear water channel structure 13, which greatly reduces the probability of the water channel structure 13 being blocked by dirt.

[0049] Optionally, the filter assembly 2 is provided with a first connection structure 21, and a second connection structure 121 is provided on the inner wall of the waterway structure 13, and the filter assembly 2 is suitable for being installed at the waterway structure 13 through the first connection structure 21 and the second connection structure 121. Therefore, the filter assembly 2 and the waterway structure 13 are designed in this way, and under the action of the first connection structure 21 and the second connection structure 121, it is convenient for the filter assembly 2 to be installed at the waterway structure 13.

[0050] In one embodiment, the first connection structure 21 includes an elastic buckle 212 provided on the filter assembly 2, and the second connection structure 121 includes a convex structure 1211 provided on the inner wall of the waterway structure 13, and the elastic buckle 212 is suitable for engaging with the convex structure 1211. Therefore, the design of the elastic buckle 212 and the convex structure 1211 is not only simple in structure and easy to manufacture, but also after the elastic buckle 212 is engaged with the convex structure 1211, the filter assembly 2 can be firmly installed above the waterway structure 13.

[0051] In this embodiment, Figure 7 , 8 As shown, the buckle of the elastic buckle 212 is connected with the convex structure 1211, and the elastic buckle 212 is extended to form a wrench 211. When the filter assembly 2 needs to be removed for cleaning, it is only necessary to turn the wrench 211 to disengage the buckle of the elastic buckle 212, and then the filter assembly 2 can be removed; after the assembly is completed, due to the presence of the heat exchanger 3, the wrench 211 cannot be turned, which plays a self-locking role. At the same time, it is preferred that the convex structure 1211 is set on the side wall of the waterway structure 13 close to the air duct. Since the wrench 211 is turned away from the air duct, after the heat exchanger 3 is disassembled, the wrench 211 has a larger turning space, which is convenient for it to be turned and separated from the convex structure 1211.

[0052] In this embodiment, the number of the elastic buckle 212 and the convex structure 1211 is not limited, and the two can be one, two or three. Figure 1 , 3 As shown, there are two elastic buckles 212, which are evenly distributed on the filter assembly 2. Similarly, two convex structures 1211 are provided on the side wall of the waterway structure 13 to cooperate with the elastic buckles 212. When the filter assembly 2 is installed on the waterway structure 13, the elastic buckles 212 and the convex structures 1211 form a snap connection.

[0053] In another embodiment, the first connection structure 21 includes a latch provided on the filter assembly 2, and the second connection structure 121 includes a pin hole provided on the inner wall of the waterway structure 13, and the latch is suitable for plugging into the pin hole. Thus, the design of the latch and the pin hole is not only simple in structure and easy to manufacture, but also after the latch and the pin hole are plugged into each other, the filter assembly 2 can be firmly installed above the waterway structure 13.

[0054] Optionally, the filter assembly 2 is provided with a first positioning structure 22, the base body 1 is provided with a water channel rib 131, the water channel rib 131 faces the water channel structure 13 to form a side wall of the water channel structure 13, and the filter assembly 2 is suitable for cooperating with the water channel rib 131 through the first positioning structure 22 to locate the position of the filter assembly 2. Therefore, the design of the filter assembly 2 cooperating with the water channel rib 131 is such that, under the action of the first positioning structure 22, it is convenient to first realize the positioning between one side of the filter assembly 2 and the water channel structure 13 during assembly.

[0055] Optionally, the first positioning structure 22 is a slot structure provided on the filter assembly 2, and the waterway rib 131 is suitable for extending into and being fixed in the slot structure. Thus, the filter assembly 2 and the waterway structure 13 are designed in this way, and under the action of the first positioning structure 22, it is convenient to first realize the positioning between the filter assembly 2 and the waterway structure 13 during assembly.

[0056] In this embodiment, the water channel ribs 131 are arranged along the length direction (X-axis direction) of the water channel structure 13 , so the slot structure is a slot-shaped structure on the filter screen assembly 2 in the X-axis direction.

[0057] Alternatively, if Figure 3 , 4 As shown, the slot structure includes a first slot structure 221 and a second slot structure 222. The first slot structure 221 matches the shape of the water channel rib 131. Along the depth direction of the second slot structure 222, the cross-sectional area of ​​the second slot structure 222 in the horizontal direction gradually decreases. Therefore, the slot structure is designed in this way, and the second slot structure 222 plays a guiding role, which facilitates the rapid loading and unloading of the water channel rib 131 and the slot structure. The first slot structure 221 plays a role in limiting the water channel rib 131 to prevent it from moving. When initially fitting, the fitting surface is large and easy to assemble; then with further fitting, the fitting surface gradually decreases until the water channel rib 131 enters the first slot structure 221 to achieve positioning.

[0058] In this embodiment, the horizontal direction refers to: Figure 3 As shown, the direction where the XY plane is located. The cross-sectional area of ​​the second slot structure 222 in the horizontal direction refers to: the cross-sectional area of ​​the second slot structure 222 on the XY plane.

[0059] In this embodiment, Figure 4 As shown, the second groove structure 222 is in the shape of a trumpet. When cooperating with the water channel rib 131, since the size of the trumpet mouth is larger than the width of the water channel rib 131, the water channel rib 131 is convenient to enter the second groove structure 222. At the same time, under the guidance of the second groove structure 222, the water channel rib 131 is convenient to enter the first groove structure 221, thereby realizing the assembly of the filter screen assembly 2 and the water channel rib 131.

[0060] Optionally, the filter assembly 2 is provided with a first limiting structure 23, and the waterway rib 131 is provided with a second limiting structure 111, and the filter assembly 2 is suitable for positioning the filter assembly 2 through the first limiting structure 23 and the second limiting structure 111. Therefore, the filter assembly 2 and the waterway structure 13 are designed in this way, and under the action of the first limiting structure 23 and the second limiting structure 111, it is convenient to first realize the positioning between the filter assembly 2 and the waterway structure 13 during assembly.

[0061] In one embodiment, if Figure 2 , 9 As shown, the first limiting structure 23 includes a limiting groove structure 231 provided on the filter assembly 2, and the second limiting structure 111 includes a limiting convex 1111 provided on the water channel rib 131, and the limiting convex 1111 is suitable for extending into the limiting groove structure 231. Therefore, the design of the limiting groove structure 231 and the limiting convex 1111 is not only simple in structure and convenient for production and manufacturing, but also convenient for first realizing the positioning between the filter assembly 2 and the water channel structure 13 during assembly after the limiting convex 1111 extends into the slot structure.

[0062] In this embodiment, Figure 2 , 5 As shown, the filter screen assembly 2 includes a protrusion structure 24, and a slot structure is provided at the bottom of the protrusion structure 24 (the side facing the water channel rib 131), and a limiting groove structure 231 is provided at the junction of the upper part (the side away from the water channel rib 131) and the front part (the side away from the water channel structure 13) of the protrusion structure 24. The limiting groove structure 231 is communicated with the slot structure. At the same time, the limiting convex bump 1111 is preferably located above the water channel rib 131. Therefore, it is not only convenient for the limiting groove structure 231 and the limiting convex bump 1111 to cooperate with each other, but also has an anti-mistake effect, which can speed up the assembly efficiency of the filter screen assembly 2.

[0063] In this embodiment, the number of the limiting groove structure 231 and the limiting convex bump 1111 is not limited, and the two can be one, two or three. Figure 2 , 35, the first limiting structure 23 is a limiting groove structure 231 provided on the filter assembly 2, and the limiting groove structure 231 is located in the middle of the filter assembly 2, and the second limiting structure 111 is a limiting convex 1111 provided on the waterway rib 131. When the filter assembly 2 is installed on the waterway structure 13, the slot structure is aligned with the limiting convex 1111 to achieve pre-positioning, and then the wrench 211 is turned to make the elastic buckle 212 cooperate with the convex convex structure 1211, so as to achieve the clamping connection between the elastic buckle 212 and the convex convex structure 1211.

[0064] Optionally, the limiting groove structure 231 and the limiting convex bump 1111 are provided with matching chamfered structures. Thus, the limiting groove structure 231 and the limiting convex bump 1111 are provided with chamfered structures to form a guide structure, which is conducive to the rapid disassembly and assembly of the filter assembly 2.

[0065] In this embodiment, Figure 2 , 5 As shown, the limiting groove structure 231 forms a chamfered structure at the junction with the second groove structure 222, and the limiting convex bump 1111 forms a chamfered structure at the upper part. When the limiting convex bump 1111 enters the limiting groove structure 231 from the slot structure, the chamfered structures of the two cooperate with each other, which not only plays a guiding role, but also prompts the limiting convex bump 1111 to enter the limiting groove structure 231.

[0066] In this embodiment, the water channel rib 131 is provided with a through groove structure penetrating along the Y-axis direction. The filter screen assembly 2 extends into the through groove structure and cooperates with the water channel rib through the slot structure. Thus, the through groove structure serves the purpose of assisting in positioning the filter screen assembly 2 and the water channel rib 131, and together with the limiting groove structure 231 and the limiting convex hump 1111, realizes the function of pre-filtering the screen assembly 2 and the water channel rib 131, thereby facilitating the subsequent clamping of the elastic buckle 212 and the convex hump structure 1211.

[0067] In another embodiment, the first limiting structure 23 includes an insert block provided on the filter assembly 2, and the second limiting structure 111 includes a groove provided on the waterway rib 131, and the plug is suitable for extending into the groove. Therefore, the design of the insert block and the groove is not only simple in structure and convenient for production and manufacturing, but also convenient for first realizing the positioning between the filter assembly 2 and the waterway structure 13 during assembly after the insert block extends into the groove.

[0068] Alternatively, if Figure 6As shown, the base body 1 includes a first base 11 and a second base 12 that are detachably connected, the first base 11 is provided with the water channel structure 13, and a portion of the filter assembly 2 is suitable for being located between the first base 11 and the second base 12. Thus, a portion of the filter assembly 2 is located between the first base 11 and the second base 12, so that the condensed water on the heat exchanger 3 can enter the water channel structure 13.

[0069] In this embodiment, Figure 6 As shown, the second base 12 is located above the first base 11 , and the first base 11 and the second base 12 form a step structure at the junction, so as to facilitate the condensed water of the heat exchanger 3 to flow into the water channel structure 13 .

[0070] In this embodiment, a portion of the filter assembly 2 is located between the first base 11 and the second base 12. When the filter assembly 2 needs to be disassembled, the first base 11 and the second base 12 are separated first. At this time, the heat exchanger 3 is also separated from the first base. Then, the elastic buckle 212 is pushed to separate the filter assembly 2 from the inner wall of one side of the water channel structure. Then, the slot structure is pulled away from the water channel rib 131 to realize the disassembly of the filter assembly 2, thereby cleaning the filter assembly 2 and the water channel structure 13.

[0071] Another embodiment of the present invention provides an air conditioner, comprising any base assembly as described above.

[0072] After adopting the air conditioner of this embodiment, the filter assembly 2 is arranged above the water channel structure 13, and after assembly is completed, the filter assembly 2 is located between the water channel structure 13 and the heat exchanger 3. When condensed water drips from the fins of the heat exchanger 3, the condensed water is filtered by the filter assembly 2, which can make the dirt remain on the filter assembly 2. The filtered condensed water enters the water channel structure 13, which greatly reduces the dirt blockage of the water channel structure 13.

[0073] In this embodiment, Figure 6 As shown, it also includes a heat exchanger 3. After the heat exchanger 3 and the base assembly are assembled, the heat exchanger 3 is located on one side of the water channel structure 13 and is supported on the first base 11. Therefore, when the heat exchanger 3 generates condensed water, under the action of gravity, the condensed water is filtered through the filter net assembly 2 and flows into the water channel structure 13.

[0074] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
