Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, and more specifically, to an air duct assembly and an air conditioner having the same. Background Technology

[0002] Currently, air conditioner indoor units mainly rely on the bottom casing duct to guide the airflow blown by the cross-flow fan to the air outlet of the indoor unit, thereby achieving airflow distribution. During the operation of the indoor unit, a large amount of condensate is generated at the evaporator, making the internal environment relatively humid. Furthermore, because external impurities can easily enter the bottom casing duct of the indoor unit through the air outlet, mold can easily grow on the air guide wall of the bottom casing duct after long-term operation, resulting in the indoor unit blowing out air with a sour and foul odor.

[0003] However, when the above problems occur in the indoor unit of the air conditioner, due to the narrow air outlet of the indoor unit, the small space between the bottom shell air duct and the cross-flow fan, and the fact that the rear of the bottom shell air duct is blocked by the cross-flow fan blades, users can only clean the bottom shell air duct after completely disassembling the indoor unit. This results in extremely low cleaning efficiency and great cleaning difficulty, affecting the user experience. Summary of the Invention

[0010] Furthermore, the second limiting structure is disposed on the mounting base of the flow guiding structure. The mounting base has a first snap-fit ​​structure and the mounting surface has a second snap-fit ​​structure. One of the first snap-fit ​​structure and the second snap-fit ​​structure is a recess, and the other of the first snap-fit ​​structure and the second snap-fit ​​structure is a protrusion.

[0038] To address the difficulty of cleaning the bottom casing air duct of the indoor unit of an air conditioner in the prior art, this application provides an air duct assembly and an air conditioner having the same.

[0039] Example 1

[0040] like Figures 1 to 8 As shown, the air duct assembly includes: an air duct body 10, which is disposed inside the housing 1 of the air conditioner and located on one side of the fan structure 2 of the air conditioner; and a guide member 20, which is movably disposed on the air duct body 10 and has a guide surface 21 for guiding the airflow blown out by the fan structure 2 to the air outlet 101 of the housing 1. The air duct body 10 is provided with a plurality of limiting parts 11 for limiting and stopping the guide member 20. The plurality of limiting parts 11 surround to form a fixed space for fixing the guide member 20. At least some of the limiting parts 11 are detachably disposed. When these limiting parts 11 are detached from the air duct body 10, the fixed space forms an opening communicating with the air outlet 101, and the guide member 20 moves to the outside of the housing 1 through the opening and the air outlet 101 in sequence.

[0041] Applying the technical solution of this embodiment, the air duct body 10 of the air duct assembly is disposed inside the housing 1 of the air conditioner. The air duct body 10 is located on one side of the fan structure 2 of the air conditioner. The guide member 20 is movably disposed on the air duct body 10 and has a guide surface 21. The guide surface 21 is used to guide the airflow blown out by the fan structure 2 to the air outlet 101 of the housing 1. The air duct body 10 is provided with a plurality of limiting parts 11 for limiting and stopping the guide member 20. The plurality of limiting parts 11 surround to form a fixed space for fixing the guide member 20. At least some of the limiting parts 11 are detachably disposed. When these limiting parts 11 are detached from the air duct body 10, the fixed space forms an opening communicating with the air outlet 101. The guide member 20 moves to the outside of the housing 1 in sequence through the opening and the air outlet. In this embodiment, the airflow blown out by the fan structure 2 is guided by the detachable air guide 20. When the air conditioner has been running for a long time and the surface of the air guide 20 becomes moldy and produces odors, the user can remove part of the limiting part 11 through the air outlet 101. At this time, the air guide 20 can be moved, and the air guide 20 can be pulled out through the opening formed by the fixed space and the air outlet 101, and the air guide surface 21 of the air guide 20 can be cleaned. This solves the problem of the difficulty in 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 air guide 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 air guide 20 and ensure that the air guide 20 has high airflow stability.

[0042] like Figures 1 to 6 As shown, the duct body 10 has a mounting surface 12, and the guide member 20 is mounted on the mounting surface 12. The first portion 111 of the limiting portion 11 is located on the side of the guide member 20 to limit and stop the guide member 20 in the length direction and / or width direction. The second portion 112 of the limiting portion 11 is located on the side of the guide member 20 away from the duct body 10 to limit and stop the guide member 20 in the height direction. In this way, the above arrangement allows the fixed space formed by the multiple limiting portions 11 to completely fix the guide member 20 (the second portion 112 limiting and stopping the guide member 20 in the height direction prevents the guide member 20 from falling off the mounting surface 12).

[0043] In this embodiment, the flow guide 20 is generally rectangular in shape.

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

[0045] In this embodiment, the first limiting structure 30 is a protruding rib machined on the mounting surface 12, and its overall shape is an L-shaped plate. The first limiting member 31 and the second limiting member 32 are two plate segments of it. The plate surface of the first limiting member 31 facing the flow guide 20 is used to limit and stop the flow guide 20, so as to form the first part 111 through the plate surface. The plate surface of the second limiting member 32 facing the flow guide surface 21 of the flow guide 20 is used to limit and stop the flow guide 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. The duct assembly also includes: a guide structure 40, disposed on the mounting surface 12 and located on the side of the guide member 20 near the air outlet 101, the guide structure 40 being used to guide the airflow direction towards the air outlet 101; and a second limiting structure 50, disposed on the guide structure 40. At least a portion of the outer surface of the guide structure 40 is used to limit and stop the guide member 20, forming a first portion 111 through this portion 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 a portion of the outer surface of the second limiting structure 50 is used to limit and stop the guide member 20, forming a second portion 112 through this portion of the outer surface. Thus, through the cooperation between the first limiting structure 30, the guide structure 40, and the second limiting structure 50, the guide member 20 is effectively initially fixed along its width direction (air outlet direction). Meanwhile, this embodiment cleverly utilizes the original airflow guiding structure 40 on the air duct body 10, which not only reduces the structural complexity of the second limiting structure 50, but also allows staff to make direct improvements on the original air conditioner.

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

[0048] Specifically, the second limiting structure 50 is plate-shaped, and its plate surface facing the flow guide 20 is used to limit and stop the flow guide 20 so as 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 guide member 20 away from the air outlet 101, it should be adjusted accordingly during actual installation based on the structure of the air duct body 10, such as... Figure 3 and Figure 4 As shown, the mounting surface 12 is also provided with a guide strip 16 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 airflow noise. At this time, the first limiting structure 30 is positioned on the side of the guide strip 16 close to 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 the user cannot clean. For example... Figure 8 As shown, the mounting surface 12 is provided with a guide strip 16, and the first limiting structure 30 should be set 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 airflow guiding structure 40 includes a mounting base 41, which is disposed on the mounting surface 12; the airflow guiding fan blade 42 is rotatably disposed on the mounting base 41 so as to adjust the airflow guiding direction of the airflow guiding structure 40 during the rotation of the airflow guiding fan blade 42, thereby realizing the adjustment of the air supply direction of the air conditioner.

[0051] like Figure 3 and Figure 6 As shown, the second limiting structure 50 is disposed on the mounting base 41 of the flow guiding structure 40. The mounting base 41 has a first snap-fit ​​structure 411, and the mounting surface 12 has a second snap-fit ​​structure 13. One of the first snap-fit ​​structure 411 and the second snap-fit ​​structure 13 is a recess, and the other of the first snap-fit ​​structure 411 and the second snap-fit ​​structure 13 is a protrusion. The protrusion extends into the recess and snaps into it, so that the mounting base 41 and the second limiting structure 50 located on the mounting base 41 are detachably disposed. 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 for workers to disassemble the small second limiting structure 50. At the same time, the above arrangement also makes the structure of the first snap-fit ​​structure 411 and the second snap-fit ​​structure 13 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of workers.

[0052] In this embodiment, at least a portion of the outer surface of the mounting base 41 forms a first portion 111. In this way, the above arrangement cleverly utilizes the original airflow guiding structure 40 inside the air conditioner. By forming the first portion 111 through the mounting base 41, the structural complexity of the second limiting structure 50 can be reduced, and its design difficulty and manufacturing cost can be lowered.

[0053] Specifically, the second limiting structure 50 installed on the mounting base 41 will not rotate with the guide fan blade 42 to ensure that the second limiting structure 50 has high limiting reliability.

[0054] In this embodiment, the first snap-fit ​​structure 411 is a snap-fit ​​recess, and the second snap-fit ​​structure 13 is a snap-fit ​​protrusion. The snap-fit ​​protrusion extends into the snap-fit ​​recess and engages with it.

[0055] In other embodiments not shown in the accompanying drawings, the first snap-fit ​​structure 411 is a snap-fit ​​protrusion, and the second snap-fit ​​structure 13 is a snap-fit ​​recess.

[0056] It should be noted that this embodiment does not specifically limit the structure of the snap-fit ​​protrusion and snap-fit ​​recess; that is, it is sufficient to ensure that the flow guiding structure 40 is detachable.

[0057] Specifically, in the original air conditioner, the airflow guiding structure 40 was originally detachable. In this embodiment, the original installation method of the airflow guiding structure 40 is further cleverly utilized so that the user can remove the second limiting structure 50 at the same time while removing the large airflow guiding structure 40.

[0058] like Figure 7 As shown in the attached figure, this is a cross-sectional view of the air duct body 10 after the airflow guiding structure 40 has been disassembled. It can be seen that, due to the loss of the limiting stop of the airflow guiding structure 40 and the second limiting structure 50, the fixed space as a whole forms an opening communicating with the air outlet 101, thereby allowing the staff to pull out and disassemble the airflow guiding component 20 located in the fixed space.

[0059] In other embodiments not shown in the figure, a first limiting structure 30 is provided on both sides of the guide member 20 along the direction from the guide member 20 to the air outlet 101. The first limiting structure 30, located near the air outlet 101 relative to the guide member 20, is detachably provided. This first limiting structure 30 has a first engaging portion, and the air duct body 10 has a second engaging portion. One of the first and second engaging portions is a engaging recess, and the other is a engaging protrusion. The engaging recess extends into the engaging protrusion and engages with it. Thus, the above arrangement, through the engaging engagement between the first and second engaging portions, enables the detachable provision of the first limiting structure 30 located at the air outlet 101. That is, the user can manually remove the first limiting structure 30 to remove its limiting stop on the guide member 20, thereby allowing the guide member 20 to be pulled out and disassembled. Meanwhile, the above-mentioned settings also make the detachable limiting structure at the air outlet 101 more flexible and diverse, adapting to different working conditions and usage needs, and improving the processing flexibility of the staff.

[0060] In other embodiments not shown in the figure, the specific structure of the first snap-fit ​​part and the second snap-fit ​​part is not limited, as long as it is ensured that the snap-fit ​​of the first limiting structure 30 located at the air outlet 101 can be realized so as to achieve its fixing and disassembly.

[0061] like Figures 1 to 3 and Figure 5 As shown, the main body 10 of the air duct includes an arc-shaped air duct base plate 14, which is arranged around the fan structure 2. The surface of the arc-shaped air duct base plate 14 facing the fan structure 2 forms a mounting surface 12. The guide member 20 is an arc-shaped plate, with one arc-shaped surface of the guide member 20 fitting against the mounting surface 12, allowing the guide member 20 to be slidably mounted on the mounting surface 12. The other arc-shaped surface of the guide member 20 forms a guide surface 21. This arrangement allows the guide member 20 to slide along the mounting surface 12, meaning the user can operate the guide member 20 to slide along the mounting surface 12 to remove it. This avoids interference between the guide member 20 and other internal structures of the air conditioner, thus reducing the difficulty of disassembly for the user. Simultaneously, this arrangement also allows the guide surface 21 to be arranged around the fan structure 2, ensuring high airflow reliability.

[0062] like Figures 1 to 3 and Figure 5As shown, the main body 10 of the air duct also includes an air duct side plate 15, which is disposed on the mounting surface 12. At least one air duct side plate 15 is disposed on both sides of the guide member 20 along the direction perpendicular to the airflow. The air duct assembly also includes a third limiting structure 60, disposed on the air duct side plate 15, located on the side of the guide member 20 away from the mounting surface 12. At least a portion of the surface of the air duct side plate 15 is positioned against the guide member 20 to form a first portion 111; at least a portion of the outer surface of the third limiting structure 60 is positioned against the guide member 20 to form a second portion 112. Thus, through the cooperation between the air duct side plate 15 and the third limiting structure 60, the guide member 20 is further fixed along its length. Meanwhile, this embodiment cleverly utilizes the air duct side plate 15 of the air duct body 10, which not only reduces the structural complexity of the third limiting structure 60, but also allows staff to make direct improvements on the original air conditioner.

[0063] Specifically, there are two air duct side plates 15, which are located on both sides of the air guide 20. In fact, during the process of pulling and disassembling the air guide 20, the air duct side plates 15 can also guide the movement direction of the air guide 20, so as to further reduce the difficulty of pulling and disassembling for users.

[0064] In this embodiment, the third limiting structure 60 is a protruding rib machined on the side plate 15 of the air duct. It is plate-shaped. The plate surface of the third limiting structure 60 facing the guide member 20 is used to limit and stop the guide member 20, so as to form the second part 112 through the plate surface.

[0065] Optionally, multiple third limiting structures 60 are located on one side of the flow guide 20, and these multiple third limiting structures 60 are spaced apart along the extending direction of the flow guide 20. In this way, the above arrangement can increase the mating area between the third limiting structure 60 and the flow guide 20, thereby improving the fixation stability of the flow guide 20.

[0066] Specifically, multiple third limiting structures 60 are spaced apart along the width direction of the guide member 20.

[0067] As it is Figures 1 to 5 As shown, the guide member 20 is plate-shaped, forming a guide surface 21 facing the plate surface of the fan structure 2. At least a portion of the guide member 20 is made of antibacterial material; and / or, an antibacterial layer is provided on the guide surface 21, at least a portion of which is made of antibacterial material. This design simplifies the structure of the guide member 20, making it easier to manufacture and reducing its processing cost. Furthermore, it prevents mold growth on the guide surface 21, reducing the frequency of cleaning and improving the user experience.

[0068] In this embodiment, an antibacterial layer is provided on the flow 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 housing 1, a fan structure 2 and an air duct assembly. The fan structure 2 and the air duct assembly are both disposed inside the housing 1. 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 housing 1. The air duct assembly is the aforementioned air duct assembly.

[0070] Example 2

[0071] The difference between the air duct assembly in Example 2 and Example 1 is that the structure of the third limiting structure 60 is different.

[0072] like Figure 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. This arrangement provides the third limiting structure 60 with a larger mating area, thus improving its guiding effect. It also ensures that the overall structure of the third limiting structure 60 is intact and gapless, preventing the edge of the guide member 20 from getting stuck in gaps during the user's pulling and unpulling process, further reducing the difficulty for the user in pulling and unpulling the guide member 20.

[0073] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0074] The air duct assembly has its main body housed within the air conditioner's casing. The main body is located on one side of the air conditioner's fan structure. A guide element is movably mounted on the main body and has a guiding surface, which directs the airflow blown by the fan structure towards the air outlet of the casing. The main body has multiple limiting parts for stopping and positioning the guide element. These limiting parts surround and form a fixed space for fixing the guide element. At least some of the limiting parts are detachable. When these limiting parts are removed from the main body, the fixed space forms an opening communicating with the air outlet. The guide element then moves sequentially through the opening and the air outlet to the outside of the casing. In this way, this application effectively guides the airflow from the fan structure through a detachable air guide. When the air conditioner has been running for a long time and the surface of the air guide becomes moldy and produces odors, the user can remove part of the limiting part through the air outlet. At this time, the air guide can be moved, allowing it to be pulled out through the opening formed by the fixed space and the air outlet, and the air guiding surface of the air guide can be cleaned. This solves the problem of the difficulty in cleaning the bottom shell air duct of the indoor unit of the air conditioner in the prior art. At the same time, after the air guide is cleaned and 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 air guide, ensuring that the air guide has high air guiding stability.
