[0001] The present invention relates to the technical field of air conditioners, and in particular to a base assembly and an air conditioner. Background Art

[0002] During the cooling process of the air conditioner, after the air exchanges heat at the heat exchanger, condensed water will be generated in the heat exchanger and flow along the heat exchanger fins to the water channel structure. There are supporting ribs and bosses in the water channel structure to support the heat exchanger. After the air conditioner has been working for a long time, dust is easily collected in the water channel structure, causing blockage and odor. It needs to be cleaned regularly, but when cleaning the water channel structure, it is often inconvenient to scrub and the cleaning is not thorough. Summary of the invention

[0003] The problem solved by the invention is how to facilitate the cleaning of the water channel structure and prevent the water channel structure or the water outlet from being blocked.

[0004] In order to solve the above problems, the present invention provides a base assembly, including a filter assembly and a base body provided with an air duct, the base body is provided with a water channel structure on one side close to the air outlet of the air duct, the filter assembly is detachably arranged in the water channel structure, and a water flow channel is formed between the filter assembly and the water channel structure.

[0005] In this way, a filter assembly is provided in the water channel structure. When condensed water drips from the heat exchanger fins, it is filtered through the filter assembly, which can leave the dirt on the filter assembly. The filtered condensed water enters the water flow channel, which greatly reduces the possibility of dirt and blockage in the water channel structure.

[0006] Optionally, the filter screen assembly is provided with a first connection structure, and a second connection structure is provided on the inner wall of the water channel structure, and the filter screen assembly is suitable for being installed in the water channel structure through the first connection structure and the second connection structure.

[0007] In this way, by designing the filter assembly and the water channel structure, the filter assembly can be easily installed in the water channel structure under the action of the first connecting structure and the second connecting structure.

[0008] Optionally, the first connection structure includes an elastic buckle provided on the filter assembly, and the second connection structure includes a convex structure provided on the inner wall of the water channel structure, and the elastic buckle is suitable for being snap-fitted with the convex structure.

[0009] In this way, the design of the elastic buckle and the convex structure is not only simple in structure and easy to manufacture, but also the filter assembly can be firmly installed in the waterway structure after the elastic buckle is snap-fitted with the convex structure.

[0010] Optionally, a limiting structure is further included, wherein the limiting structure is arranged on the filter assembly, and the limiting structure is suitable for limiting the position of the heat exchanger on the filter assembly.

[0011] In this way, the existence of the limiting structure can limit the heat exchanger and restrict the position of the heat exchanger on the filter assembly, thereby preventing the heat exchanger from moving.

[0012] Optionally, the limiting structure is a protrusion, and the protrusion is suitable for abutting against the heat exchanger.

[0013] Optionally, a supporting structure is further included, wherein the supporting structure is arranged at the bottom of the filter screen assembly, and the supporting structure is suitable for being supported on the bottom wall of the water channel structure.

[0014] In this way, a support structure is arranged at the bottom of the filter assembly, which contacts the bottom wall of the water channel structure, and can effectively prevent the heat exchanger from compressing and deforming the filter assembly, thereby affecting its effect of filtering dirt.

[0015] Optionally, the supporting structure is a supporting rib, and the supporting rib is arranged along the width direction of the water channel structure.

[0016] In this way, the supporting ribs are arranged along the width direction of the water channel structure. Compared with being arranged along the length direction of the water channel structure, the condensed water is in contact with the supporting ribs for a shorter time in the flow direction, which can make the accumulated water in the water channel structure flow out more easily.

[0017] Optionally, the filter screen assembly is provided with a first positioning structure, and a second positioning structure is provided on the inner wall of the water channel structure, and the filter screen assembly is suitable for positioning the filter screen assembly in the water channel structure through the first positioning structure and the second positioning structure.

[0018] In this way, by designing the filter screen assembly and the water channel structure in this way, under the action of the first positioning structure and the second positioning structure, it is convenient to first realize the positioning between the filter screen assembly and the water channel structure during assembly.

[0019] Optionally, the first positioning structure includes a slot structure provided on the filter assembly, and the second positioning structure includes a limiting convex bump provided on the inner wall of the water channel structure; or, the first positioning structure includes a limiting convex bump provided on the filter assembly, and the second positioning structure includes a slot structure provided on the inner wall of the water channel structure, and the limiting convex bump is suitable for extending into the slot structure.

[0020] In this way, the design of the slot structure and the limiting convex bump is not only simple in structure and easy to manufacture, but also, after the limiting convex bump is inserted into the slot structure, it is easy to realize the positioning between the filter screen assembly and the waterway structure during assembly.

[0021] Optionally, the filter assembly includes a first hollow member, a second hollow member and a connecting member, the first hollow member and the second hollow member are respectively located at two ends of the connecting member, a groove structure is formed between the first hollow member, the second hollow member and the connecting member, the first hollow member is suitable for connecting to the side wall of the water channel structure away from the air duct, and the second hollow member is suitable for abutting against the side wall of the water channel structure close to the air duct.

[0022] In this way, the structure of the filter assembly is designed in such a way that a groove structure is formed between the first hollow part, the second hollow part and the connecting part, which is convenient for supporting the heat exchanger, and the first hollow part is suitable for connecting with the side wall of the water channel structure away from the air duct, and the second hollow part is suitable for abutting against the side wall of the water channel structure close to the air duct, thereby achieving a stable installation of the filter assembly in the water channel structure.

[0023] Optionally, a first overflow trough structure is provided on the side wall of the waterway structure, and a second overflow trough structure is provided on the second hollow member, the first overflow trough structure and the second overflow trough structure are arranged opposite to each other, and the size of the second overflow trough structure is larger than the size of the first overflow trough structure.

[0024] In this way, a second overflow trough structure is provided on the second hollow member to ensure that after adding the filter screen assembly, the first overflow trough structure on the side wall of the waterway structure will not be blocked, thereby avoiding the functional failure of the first overflow trough structure.

[0025] Optionally, a first inclined surface is provided on the first hollow member, and the first inclined surface is suitable for being inclined relative to the heat exchanger.

[0026] In this way, the existence of the first inclined surface can play a guiding role when the heat exchanger is disassembled and assembled, thereby improving the loading and unloading efficiency of the heat exchanger.

[0027] Optionally, a second inclined surface is provided on a side of the second hollow member facing the side wall of the water channel structure close to the air channel, and the second inclined surface is inclined relative to the side wall of the water channel structure close to the air channel.

[0028] In this way, after assembly, the second inclined surface is inclined relative to the side wall of the water channel structure close to the air channel, and there is a gap between the two. When the second hollow piece is about to fall out, due to the presence of the elastic buckle at the first hollow piece, the entire filter assembly will make a circular motion with the elastic buckle as the center. At this time, the second hollow piece moves upward and rubs against the side wall of the water channel structure, and the space becomes smaller and smaller, and the fit becomes tighter, thereby effectively preventing the front filter structure from falling out.

[0029] Another object of the present invention is to provide an air conditioner to solve the problem of how to facilitate cleaning of the water channel structure and prevent the water channel structure or the water outlet from being blocked.

[0030] To solve the above problems, the technical solution of the present invention is achieved as follows:

[0031] An air conditioner comprises any base assembly as described above.

[0032] The advantages of the air conditioner and the above-mentioned base assembly over the prior art are the same, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] 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.

[0051] 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.

[0052] 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 to support the heat exchanger. 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.

[0053] 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 provided with an air duct 14, the base body 1 is provided with a water channel structure 11 on one side close to the air outlet of the air duct 14, the filter screen assembly 2 is detachably arranged in the water channel structure 11, and a water flow channel is formed between the filter screen assembly 2 and the water channel structure 11.

[0054] After adopting the base assembly of this embodiment, a filter mesh assembly 2 is provided in the water channel structure 11. When condensed water drips from the fins of the heat exchanger 3, it is filtered by the filter mesh assembly, so that the dirt can remain on the filter mesh assembly 2. The filtered condensed water enters the water flow channel, which greatly reduces the dirt blockage of the water channel structure 11.

[0055] Compared with the existing water channel structure 11, in this embodiment, the bottom wall of the water channel structure 11 eliminates the bosses and supporting ribs, which facilitates the cleaning of the water channel structure 11 after the filter assembly is disassembled, thereby effectively preventing the water channel structure 11 from being dirty and blocked.

[0056] In this embodiment, the water channel structure 11 is the front water channel structure or the rear water channel structure of the base body 1. Fig. 9 As shown, the water channel structure 11 is preferably a front water channel structure, and the filter screen assembly 2 is located inside the water channel structure 11. After the heat exchanger 3 is assembled, the filter screen assembly 2 supports the heat exchanger 3. Therefore, the condensed water dripping from the fins of the heat exchanger 3 will not directly enter the water channel structure 11. The condensed water will first be filtered by the filter screen assembly 2, so that the dirt will remain on the filter screen assembly 2, and then enter the rear water channel structure 11, which greatly reduces the probability of dirt clogging the water channel structure 11.

[0057] Optionally, the filter assembly 2 is provided with a first connection structure 211, and a second connection structure 15 is provided on the inner wall of the waterway structure 11, and the filter assembly 2 is suitable for being installed in the waterway structure 11 through the first connection structure 211 and the second connection structure 15. Therefore, the filter assembly 2 and the waterway structure 11 are designed in this way, and under the action of the first connection structure 211 and the second connection structure 15, it is convenient for the filter assembly 2 to be installed in the waterway structure 11.

[0058] In one embodiment, if Figure 5 , 7 As shown in Figures 11 and 12, the first connection structure 211 includes an elastic buckle 2111 provided on the filter assembly 2, and the second connection structure 15 includes a convex structure 151 provided on the inner wall of the waterway structure 11, and the elastic buckle 2111 is suitable for engaging with the convex structure 151. Therefore, the design of the elastic buckle 2111 and the convex structure 151 is not only simple in structure and easy to manufacture, but also after the elastic buckle 2111 is engaged with the convex structure 151, the filter assembly 2 can be firmly installed in the waterway structure 11.

[0059] In this embodiment, Figure 7As shown, the buckle of the elastic buckle 2111 is connected with the convex structure 151, and the elastic buckle 2111 extends away from the waterway structure 11 to form a wrench 212. When the filter assembly 2 needs to be removed for cleaning, it is only necessary to turn the wrench 212 to disengage the buckle, and then the filter assembly 2 can be removed; after the transfer is completed, due to the presence of the heat exchanger 3, the wrench 212 cannot be turned, which plays a self-locking role. At the same time, it is preferred that the convex structure 151 is set on the side wall of the waterway structure 11 away from the air duct. After the heat exchanger 3 is disassembled, the wrench 212 has a larger turning space, which is convenient for it to be turned and separated from the convex structure 151.

[0060] In this embodiment, the number of the elastic buckle 2111 and the convex structure 151 is not limited, and the two can be one, two or three. Figure 5 As shown, there are two elastic buckles 2111, which are evenly distributed on the filter assembly 2. Similarly, two convex structures 151 are provided on the side wall of the waterway structure 11 to cooperate with the elastic buckles 2111. When the filter assembly 2 is installed on the waterway structure 11, the elastic buckles 2111 and the convex structures 151 form a snap connection.

[0061] In another embodiment, the first connection structure 211 includes a latch provided on the filter assembly 2, and the second connection structure 15 includes a pin hole provided on the inner wall of the waterway structure 11, 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 11.

[0062] Optionally, a limiting structure 25 is further included, and the limiting structure 25 is arranged on the filter assembly 2, and the limiting structure 25 is suitable for limiting the position of the heat exchanger 3 on the filter assembly 2. Therefore, the existence of the limiting structure 25 can limit the position of the heat exchanger 3 and limit the position of the heat exchanger 3 on the filter assembly 2, thereby preventing the heat exchanger 3 from moving.

[0063] like Figure 2 , 3 As shown, the limiting structure 25 is a convex block, and the convex block is suitable for abutting against the heat exchanger 3. Therefore, under the action of the convex block, the displacement of the heat exchanger 3 is limited and no movement occurs.

[0064] Optionally, a support structure 24 is further included, and the support structure 24 is arranged at the bottom of the filter assembly 2, and the support structure 24 is suitable for supporting the bottom wall of the water channel structure 11. Therefore, the support structure 24 is arranged at the bottom of the filter assembly 2, and it contacts the bottom wall of the water channel structure 11, which can effectively prevent the heat exchanger 3 from compressing and deforming the filter assembly 2, thereby affecting its effect of filtering dirt.

[0065] Alternatively, if Figure 6 As shown, the support structure 24 is a support rib, and the support rib is arranged along the width direction of the water channel structure 11. Therefore, the support rib is arranged along the width direction of the water channel structure 11. Compared with being arranged along the length direction of the water channel structure 11, the time that the condensed water contacts the support rib in the flow direction is shorter, so that the accumulated water in the water channel structure 11 can flow out more easily.

[0066] In this embodiment, the width direction refers to: Figure 2 As shown, the direction of the Y axis.

[0067] In this embodiment, there is no limit to the number of supporting ribs, which may be one, two, three, etc., depending on the actual situation. At the same time, in the Z-axis direction, the length of the supporting ribs is smaller than the base width of the waterway structure 11, so as to facilitate drainage.

[0068] Optionally, the filter assembly 2 is provided with a first positioning structure 26, and the inner wall of the waterway structure 11 is provided with a second positioning structure 12, and the filter assembly 2 is suitable for positioning the filter assembly 2 in the waterway structure 11 through the first positioning structure 26 and the second positioning structure 12. Therefore, the filter assembly 2 and the waterway structure 11 are designed in this way, and under the action of the first positioning structure 26 and the second positioning structure 12, it is convenient to first realize the positioning between the filter assembly 2 and the waterway structure 11 during assembly.

[0069] In one embodiment, the first positioning structure 26 includes a slot structure 4 provided on the filter assembly 2, and the second positioning structure 12 includes a limiting convex bulge 5 provided on the inner wall of the waterway structure 11; in another embodiment, the first positioning structure 26 includes a limiting convex bulge 5 provided on the filter assembly 2, and the second positioning structure 12 includes a slot structure 4 provided on the inner wall of the waterway structure 11, and the limiting convex bulge 5 is suitable for extending into the slot structure 4. Therefore, the design of the slot structure 4 and the limiting convex bulge 5 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 11 during assembly after the limiting convex bulge 5 extends into the slot structure 4.

[0070] In this embodiment, the number of the slot structure 4 and the limiting convex bump 5 is not limited, and the two can be one, two or three. Figure 2 , 34, the first positioning structure 26 is a slot structure 4 provided on the filter assembly, and the slot structure 4 is located in the middle of the filter assembly, and the second connection structure 15 is a limiting convex hull 5 provided on the inner wall of the waterway structure 11. When the filter assembly 2 is installed in the waterway structure 11, the slot structure 4 is aligned with the limiting convex hull 5 to achieve pre-positioning, and then the wrench 212 is turned to force the elastic buckle 2111 to cooperate with the convex hull structure 151, thereby achieving the clamping connection between the elastic buckle 2111 and the convex hull structure 151.

[0071] Alternatively, if Figure 6 As shown, the filter assembly 2 includes a first hollow piece 21, a second hollow piece 22 and a connecting piece 23, wherein the first hollow piece 21 and the second hollow piece 22 are respectively located at the two ends of the connecting piece 23, and a groove structure is formed between the first hollow piece 21, the second hollow piece 22 and the connecting piece 23, wherein the first hollow piece 21 is suitable for connecting with the side wall of the water channel structure 11 away from the air channel 14, and the second hollow piece 22 is suitable for abutting against the side wall of the water channel structure 11 close to the air channel 14. Thus, the structure of the filter assembly 2 is designed in this way, and a groove structure is formed between the first hollow piece 21, the second hollow piece 22 and the connecting piece 23, which is convenient for supporting the heat exchanger 3, and the first hollow piece 21 is suitable for connecting with the side wall of the water channel structure 11 away from the air channel 14, and the second hollow piece 22 is suitable for abutting against the side wall of the water channel structure 11 close to the air channel 14, thereby enabling the filter assembly 2 to be stably installed in the water channel structure 11.

[0072] Alternatively, if Figure 3 , 4 As shown, the side wall of the water channel structure 11 is provided with a first overflow trough structure 13, and the second hollow member 22 is provided with a second overflow trough structure 221. The first overflow trough structure 13 and the second overflow trough structure 221 are arranged opposite to each other, and the size of the second overflow trough structure 221 is larger than the size of the first overflow trough structure 13. Therefore, the second hollow member 22 is provided with the second overflow trough structure 221, ensuring that after adding the filter assembly, the first overflow trough structure 13 on the side wall of the water channel structure 11 will not be blocked, thereby avoiding the first overflow trough structure 13 from losing its function.

[0073] In this embodiment, Figure 2 , 10 As shown, the first overflow trough structure 13 is arranged on the side wall of the water channel structure 11 close to the air channel 14. Since the second hollow member 22 abuts against the side wall of the water channel structure 11 close to the air channel 14, it is more reasonable to arrange the second overflow trough structure 221 on the second hollow member 22.

[0074] In this embodiment, the size of the second overflow trough structure 221 is greater than the size of the first overflow trough structure 13, which means that the vertical depth (Z-axis direction) and the horizontal length (X-axis direction) of the second overflow trough structure 221 are both greater than the vertical depth (Z-axis direction) and the horizontal length (X-axis direction) of the first overflow trough structure 13, thereby not hindering the normal operation of the first overflow trough structure 13.

[0075] Alternatively, if Fig.11 As shown, the first hollow member 21 is provided with a first inclined surface 213, which is suitable for being inclined relative to the heat exchanger 3. Therefore, the first inclined surface 213 can play a guiding role when the heat exchanger 3 is disassembled, thereby improving the loading and unloading efficiency of the heat exchanger 3.

[0076] In this embodiment, a portion of the heat exchanger 3 extends into the water channel structure 11 and is supported on the filter assembly 2 , so that the first inclined surface 213 is suitable for being inclined relative to the portion of the heat exchanger 3 extending into the water channel structure 11 .

[0077] Alternatively, if Figure 8 As shown, the second hollow part 22 is provided with a second inclined surface 222 on the side of the side wall of the water channel structure 11 close to the air channel 14, and the second inclined surface 222 is inclined relative to the side wall of the water channel structure 11 close to the air channel 14. Therefore, after assembly, the second inclined surface 222 is inclined relative to the side wall of the water channel structure 11 close to the air channel 14, and there is a gap between the two. When the second hollow part 22 is about to fall out, due to the presence of the elastic buckle 2111 at the first hollow part 21, the entire filter assembly 2 will make a circular motion with the elastic buckle 2111 as the center. At this time, the second hollow part 22 moves upward, rubbing against the side wall of the water channel structure 11, and the space becomes smaller and smaller, and the fit becomes tighter, thereby effectively preventing the front filter structure from falling out.

[0078] In this embodiment, the lower end of the second hollow member 22 is abutted against the side wall of the water channel structure 11 close to the air duct 14. Since the second hollow member 22 is provided with a second inclined surface, the distance from the lower end to the upper end of the second hollow member 22 relative to the side wall of the water channel structure 11 close to the air duct 14 gradually increases.

[0079] Another embodiment of the present invention provides an air conditioner, comprising any base assembly as described above.

[0080] After adopting the air conditioner of this embodiment, a filter assembly 2 is provided in the water channel structure 11. When condensed water drips from the fins of the heat exchanger 3, it is filtered by the filter assembly, so that the dirt can remain on the filter assembly 2. The filtered condensed water enters the water flow channel, which greatly reduces the dirt blockage of the water channel structure 11.

[0081] In this embodiment, Fig. 9 , 10 As shown, the air conditioner further includes a heat exchanger 3 , which is located above the air duct 14 , and one end of the heat exchanger 3 is located on the filter assembly 2 and abuts against the limiting structure 25 of the filter assembly 2 .

[0082] 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.
