[0002] At present, the indoor unit of the air conditioner mainly relies on the bottom shell air duct to guide the airflow blown by the cross-flow fan to the air outlet of the indoor unit of the air conditioner, thereby realizing the airflow blowing of the indoor unit of the air conditioner. During the operation of the indoor unit of the air conditioner, a large amount of condensation water will be generated at the evaporator inside the indoor unit, and the internal environment is relatively humid. In addition, since external impurities can easily enter the bottom shell air duct in the indoor unit of the air conditioner through the air outlet, mold is easy to grow on the air guide wall surface of the bottom shell air duct of the indoor unit of the air conditioner after long-term operation, which will cause the indoor unit of the air conditioner to blow out airflow with a sour and smelly odor.

[0038] In order to solve the problem that it is difficult to clean the bottom shell air duct of the air conditioner indoor unit in the prior art, the present application provides an air duct assembly and an air conditioner having the same.

[0039] Embodiment 1

[0040] like Figures 1 to 8 As shown, the air duct assembly includes: an air duct main body 10, which is arranged in the shell 1 of the air conditioner, and the air duct main body 10 is located on one side of the fan structure 2 of the air conditioner; a guide member 20, which is movably arranged on the air duct main body 10, and the guide member 20 has a guide surface 21, and the guide surface 21 is used to guide the airflow blown out through the fan structure 2 to the air outlet 101 of the shell 1; wherein, a plurality of limiting portions 11 for limiting and stopping the guide member 20 are arranged on the air duct main body 10, and the plurality of limiting portions 11 surround and form a fixed space for fixing the guide member 20, and at least part of the limiting portions 11 is detachably arranged. When the part of the limiting portions 11 is removed from the air duct main body 10, the fixed space forms an opening connected to the air outlet 101, and the guide member 20 moves to the outside of the shell 1 through the opening and the air outlet 101 in sequence.

[0041] According to the technical solution of this embodiment, the duct body 10 of the duct assembly is arranged in the housing 1 of the air conditioner. The duct body 10 is located on one side of the fan structure 2 of the air conditioner. The air guide 20 is movably arranged on the duct body 10 and has a guide surface 21. The guide surface 21 is used to guide the airflow blown out through the fan structure 2 to the air outlet 101 of the housing 1. Among them, the duct body 10 is provided with a plurality of limiting parts 11 for limiting and stopping with the air guide 20. The plurality of limiting parts 11 surround and form a fixed space for fixing the air guide 20. At least part of the limiting parts 11 is detachably arranged. When the part of the limiting parts 11 is removed from the duct body 10, the fixed space forms an opening connected with the air outlet 101. The air guide 20 moves to the outside of the housing 1 through the opening and the air outlet in sequence. In this way, the present embodiment actually guides the airflow blown out of the fan structure 2 through the detachable guide member 20. When the air conditioner is operated for a long time and the surface of the guide member 20 is moldy and produces odor, the user can remove part of the limiting part 11 through the air outlet 101, and the guide member 20 can be moved at this time, so that the guide member 20 can be pulled out through the opening formed by the fixed space and the air outlet 101, and the guide surface 21 of the guide member 20 can be cleaned, thereby solving the problem of the difficulty of cleaning the bottom shell air duct of the indoor unit of the air conditioner in the prior art. At the same time, after the cleaned guide member 20 is pushed back into the air conditioner through the air outlet and the opening formed by the fixed space, the user can reinstall the removed limiting part 11 to fix the guide member 20, ensuring that the guide member 20 has a high guide stability.

[0042] like Figures 1 to 6 As shown, the air duct body 10 has a mounting surface 12, and the air guide 20 is mounted on the mounting surface 12. The first part 111 of the limiting part 11 is located at the side of the air guide 20, so as to limit and stop the air guide 20 along the length direction and / or width direction of the air guide 20. The second part 112 of the limiting part 11 is located at the side of the air guide 20 away from the air duct body 10, so as to limit and stop the air guide 20 along the height direction of the air guide 20. In this way, the above arrangement enables the fixed space formed by the multiple limiting parts 11 to completely fix the air guide 20 (the second part 112 limits and stops the air guide 20 along the height direction of the air guide 20 to prevent the air guide 20 from falling off the mounting surface 12).

[0043] In this embodiment, the guide member 20 is a rectangular structure as a whole.

[0044] like Figures 1 to 3 and Figure 4As shown, the air duct assembly also includes: a first limiting structure 30, which is arranged on the mounting surface 12, and the first limiting structure 30 includes a first limiting member 31 and a second limiting member 32 which are connected to each other, the first limiting member 31 is located at the side of the air guide 20, and at least a part of the outer surface of the first limiting member 31 is used to limit and stop with the air guide 20, so as to form a first part 111 through this part of the outer surface; the second limiting member 32 is located at the side of the air guide 20 away from the mounting surface 12, and at least a part of the outer surface of the second limiting member 32 is used to limit and stop with the air guide 20, so as to form a second part 112 through this part of the outer surface. In this way, the above arrangement makes the formation of the first part 111 and the second part 112 simpler, easier to process and realize, thereby reducing the processing cost of the first limiting structure 30 capable of forming the limiting portion 11 and the processing difficulty of the staff.

[0045] In this embodiment, the first limiting structure 30 is a convex rib processed on the mounting surface 12, which is arranged in an L-shaped plate as a whole, and the first limiting member 31 and the second limiting member 32 are two plate sections thereof, respectively. The first limiting member 31 faces the plate surface of the flow guide member 20 and is used for limiting and stopping with the flow guide member 20, so as to form the first part 111 through the plate surface. The second limiting member 32 faces the plate surface of the flow guide surface 21 of the flow guide member 20 and is used for limiting and stopping with the flow guide member 20, so as to form the second part 112 through the plate surface.

[0046] like Figures 1 to 3 and Figure 6 As shown, the first limiting structure 30 is located on the side of the guide member 20 away from the air outlet 101, and the air duct assembly further includes: a guide structure 40, which is arranged on the mounting surface 12 and is located on the side of the guide member 20 close to the air outlet 101, and the guide structure 40 is used to guide the airflow direction toward the air outlet 101; a second limiting structure 50, which is arranged on the guide structure 40. Among them, at least part of the outer surface of the guide structure 40 is used to limit and stop with the guide member 20, so as to form a first part 111 through this part of the outer surface; the second limiting structure 50 is located on the side of the guide member 20 away from the mounting surface 12, and at least part of the outer surface of the second limiting structure 50 is used to limit and stop with the guide member 20, so as to form a second part 112 through this part of the outer surface. In this way, through the cooperation between the first limiting structure 30, the guide structure 40 and the second limiting structure 50, the guide member 20 is actually preliminarily fixed along the width direction (air outlet direction) of the guide member 20. At the same time, the present embodiment cleverly utilizes the guide structure 40 originally provided on the air duct body 10, which not only reduces the structural complexity of the second limiting structure 50, but also allows the staff to directly make improvements on the original air conditioner.

[0047] In this embodiment, the second limiting structure 50 is a convex rib processed on the flow guiding structure 40 .

[0048] Specifically, the second limiting structure 50 is in a plate shape, and its plate surface facing the flow guide member 20 is used for limiting and stopping with the flow guide member 20 to form the second part 112 through the plate surface.

[0049] Specifically, although the first limiting structure 30 only needs to be located on the side of the air guide 20 away from the air outlet 101, it should be adjusted accordingly in combination with the structure of the air duct body 10 during the actual installation process, such as Figure 3 and Figure 4 As shown, the mounting surface 12 is also provided with a guide strip 16 located on the side of the guide member 20 away from the air outlet 101. The guide strip 16 is mainly used to initially guide the airflow blown out by the fan structure 2 to reduce the airflow noise. At this time, the first limiting structure 30 is provided with the guide strip 16 close to the side of the guide member 20 and in close contact with the guide strip 16 to maximize the area of ​​the guide surface 21 of the guide member 20, thereby reducing the area of ​​mold growth that cannot be cleaned by the user. Figure 8 As shown, the guide strip 16 is disposed on the mounting surface 12 , and the first limiting structure 30 should be disposed at the edge of the mounting surface 12 away from the air outlet 101 to further increase the area of ​​the guide surface 21 .

[0050] like Figure 6 As shown, the guide structure 40 includes a mounting base 41, and the mounting base 41 is arranged on the mounting surface 12; the guide blades 42 are rotatably arranged on the mounting base 41 to adjust the airflow guide direction of the guide structure 40 during the rotation of the guide blades 42, thereby adjusting the air supply direction of the air conditioner.

[0051] like Figure 3 and Figure 6 As shown, the second limiting structure 50 is arranged on the mounting base 41 of the flow guiding structure 40, the mounting base 41 has a first clamping structure 411, the mounting surface 12 has a second clamping structure 13, one of the first clamping structure 411 and the second clamping structure 13 is a recess, and the other of the first clamping structure 411 and the second clamping structure 13 is a protrusion, which extends into the recess and is inscribed with the recess to engage with the recess, so that the mounting base 41 and the second limiting structure 50 located on the mounting base 41 can be detachably arranged. In this way, the above arrangement realizes the synchronous disassembly of the flow guiding structure 40 and the second limiting structure 50, which greatly reduces the difficulty of the staff to disassemble the second limiting structure 50 with a smaller volume. At the same time, the above arrangement also makes the structure of the first clamping structure 411 and the second clamping structure 13 more flexible and diverse to adapt to different working conditions and use requirements, and also improves the processing flexibility of the staff.

[0052] In this embodiment, at least part of the outer surface of the mounting base 41 forms the first portion 111. In this way, the above arrangement cleverly utilizes the original air guide structure 40 in the air conditioner, and the first portion 111 is formed by the mounting base 41, which can reduce the structural complexity of the second limiting structure 50, reduce its design difficulty and manufacturing cost.

[0053] Specifically, the second limiting structure 50 disposed on the mounting base 41 will not rotate along with the guide blades 42 , so as to ensure that the second limiting structure 50 has a high limiting reliability.

[0054] In this embodiment, the first clamping structure 411 is a clamping recess, and the second clamping structure 13 is a clamping protrusion. The clamping protrusion extends into the clamping recess and is clamped with the clamping recess.

[0055] In other embodiments not shown in the drawings, the first clamping structure 411 is a clamping protrusion, and the second clamping structure 13 is a clamping recess.

[0056] It should be noted that the present embodiment does not impose any specific restrictions on the specific structures of the clamping protrusions and the clamping recesses, that is, it is only necessary to ensure that the guide structure 40 is detachable.

[0057] Specifically, in the original air conditioner, the guide structure 40 is originally detachable. This embodiment actually further cleverly utilizes the installation form of the original guide structure 40 so that the user can remove the second limiting structure 50 simultaneously when disassembling the larger guide structure 40.

[0058] like Figure 7 As shown, the figure shows a cross-sectional view of the air duct body 10 after the air guide structure 40 is removed. It can be seen that due to the loss of the limit stop of the air guide structure 40 and the second limit structure 50, the fixed space as a whole forms an opening connected to the air outlet 101, so that the staff can pull out and remove the air guide member 20 located in the fixed space.

[0059] In other embodiments not shown in the figure, along the direction from the air guide 20 to the air outlet 101, a first limiting structure 30 is provided on both sides of the air guide 20. The first limiting structure 30 provided near the air outlet 101 relative to the air guide 20 is detachably provided, the first limiting structure 30 has a first clamping portion, the air duct body 10 has a second clamping portion, one of the first clamping portion and the second clamping portion is a clamping recess, the other of the first clamping portion and the second clamping portion is a clamping protrusion, the clamping recess extends into the clamping protrusion and is engaged with the clamping protrusion. In this way, the above-mentioned setting realizes the detachable setting of the first limiting structure 30 located at the air outlet 101 through the clamping cooperation between the first clamping portion and the second clamping portion, that is, the user can manually disassemble the first limiting structure 30 to cancel its limiting stop on the air guide 20, thereby realizing the drawing and disassembly of the air guide 20. At the same time, the above arrangement also makes the structure of the detachable limiting structure arranged at the air outlet 101 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0060] In other embodiments not shown in the figures, there is no limitation on the specific structure of the first clamping portion and the second clamping portion, and it is only necessary to ensure that the first limiting structure 30 located at the air outlet 101 can be clamped and matched to achieve its fixation and disassembly.

[0061] like Figures 1 to 3 and Figure 5 As shown, the air duct body 10 includes: an arc-shaped air duct bottom plate 14, which is arranged around the fan structure 2, and the plate surface of the arc-shaped air duct bottom plate 14 facing the fan structure 2 forms a mounting surface 12. Among them, the guide member 20 is an arc-shaped plate, and one arc-shaped plate surface of the guide member 20 is in contact with the mounting surface 12, so that the guide member 20 can be slidably arranged on the mounting surface 12, and the other arc-shaped plate surface of the guide member 20 forms a guide surface 21. In this way, the above-mentioned arrangement enables the guide member 20 to slide along the mounting surface 12, that is, the user can operate the guide member 20 to slide along the mounting surface 12 to pull out the guide member 20, thereby avoiding interference between the guide member 20 and other structures inside the air conditioner, thereby reducing the difficulty of disassembly for the user. At the same time, the Shanghai arrangement also enables the guide surface 21 to be arranged around the fan structure 2 to ensure that the guide surface 21 has a high guide reliability.

[0062] like Figures 1 to 3 and Figure 5As shown, the air duct body 10 also includes an air duct side plate 15, which is arranged on the mounting surface 12. At least one air duct side plate 15 is arranged on both sides of the air guide 20 in a direction perpendicular to the air flow. The air duct assembly also includes: a third limiting structure 60, which is arranged on the air duct side plate 15. The third limiting structure 60 is located on the side of the air guide 20 away from the mounting surface 12. Among them, the air duct side plate 15 is limited and stopped by at least part of the plate surface of the air guide 20, so as to form a first part 111 through the part of the plate surface; at least part of the outer surface of the third limiting structure 60 is limited and stopped by the air guide 20, so as to form a second part 112 through the part of the outer surface. In this way, through the cooperation between the air duct side plate 15 and the third limiting structure 60, the air guide 20 is actually further fixed along the length direction of the air guide 20. At the same time, the present embodiment cleverly utilizes the air duct side plate 15 of the air duct main body 10, which not only reduces the structural complexity of the third limiting structure 60, but also allows the staff to directly make improvements on the original air conditioner.

[0063] Specifically, there are two duct side panels 15, which are respectively located on both sides of the guide member 20. In fact, during the pulling and disassembly process of the guide member 20, the duct side panels 15 can also guide the movement direction of the guide member 20 to further reduce the pulling and disassembly difficulty of the user.

[0064] In this embodiment, the third limiting structure 60 is a convex rib processed on the air duct side plate 15, which is in the shape of a plate. The third limiting structure 60 faces the plate surface of the guide member 20 and is used to limit and stop with the guide member 20 to form the second part 112 through the plate surface.

[0065] Optionally, there are multiple third limiting structures 60 located on one side of the guide member 20, and the multiple third limiting structures 60 are arranged at intervals along the extension direction of the guide member 20. In this way, the above arrangement can increase the matching area between the third limiting structure 60 and the guide member 20 to improve the fixing stability of the guide member 20.

[0066] Specifically, a plurality of third limiting structures 60 are arranged at intervals along the width direction of the guide member 20 .

[0067] As to Figures 1 to 5 As shown, the guide member 20 is plate-shaped, so that the guide surface 21 is formed by the guide member 20 facing the plate surface of the fan structure 2. Among them, at least part of the guide member 20 is made of antibacterial material; and / or, an antibacterial layer is provided on the guide surface 21, and at least part of the antibacterial layer is made of antibacterial material. In this way, the above-mentioned setting makes the structure of the guide member 20 simpler and easier to process, thereby reducing the processing cost of the guide member 20; on the other hand, it makes it difficult for the guide surface 21 of the guide member 20 to breed mold, thereby reducing the user's cleaning frequency and improving the user's experience.

[0068] In this embodiment, an antibacterial layer is provided on the guide surface 21 , and the antibacterial layer is made of antibacterial material.

[0069] like Figure 1 As shown, this embodiment also provides an air conditioner, which includes a shell 1, a fan structure 2 and an air duct assembly. The fan structure 2 and the air duct assembly are both arranged in the shell 1, and the air duct assembly is located on one side of the fan structure 2 to guide the airflow blown out by the fan structure 2 to the air outlet 101 of the shell 1, wherein the air duct assembly is the above-mentioned air duct assembly.

[0070] Embodiment 2

[0071] The difference between the air duct assembly in the second embodiment and the first embodiment is that the structure of the third limiting structure 60 is different.

[0072] like Fig. 9 As shown, there is one third limiting structure 60 located on one side of the guide member 20, and the third limiting structure 60 is arranged in a strip shape. In this way, the above arrangement enables the third limiting structure 60 to have a larger matching area to enhance its guiding effect. At the same time, the overall structure of the third limiting structure 60 is also complete and gap-free, which can prevent the edge of the guide member 20 from getting stuck in the gap when the user pulls out the guide member 20, further reducing the difficulty of the user pulling out and removing the guide member 20.

[0073] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0074] The duct body of the duct assembly is arranged in the housing of the air conditioner, and the duct body is located on one side of the fan structure of the air conditioner. The guide member is movably arranged on the duct body and has a guide surface, and the guide surface is used to guide the airflow blown out through the fan structure to the air outlet of the housing. Among them, the duct body is provided with a plurality of limit parts for limiting and stopping with the guide member, and the plurality of limit parts surround and form a fixed space for fixing the guide member, and at least part of the limit parts is detachably arranged. When the part of the limit parts is removed from the duct body, the fixed space forms an opening connected to the air outlet, and the guide member moves to the outside of the housing through the opening and the air outlet in sequence. In this way, the present application actually guides the airflow blown out of the fan structure through a detachable guide member. When the air conditioner is running for a long time and the surface of the guide member is moldy and produces odor, the user can remove part of the limiting part through the air outlet, and the guide member can be movable at this time, so that the guide member can be pulled out through the opening formed by the fixed space and the air outlet, and the guide surface of the guide member can be cleaned, thereby solving the problem of the difficulty of cleaning the bottom shell air duct of the indoor unit of the air conditioner in the prior art. At the same time, after the cleaned guide member is pushed back into the air conditioner through the air outlet and the opening formed by the fixed space, the user can reinstall the removed limiting part to fix the guide member, ensuring that the guide member has a high guide stability.
