[0052] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with embodiments.

[0053] As Figures 1 to 6As shown, an embodiment of this utility model provides an air duct component, which includes an air duct housing 10, a filter element 20, and a sealing structure 30. The air duct housing 10 has a first connecting port 11, a second connecting port 12, and an air duct notch 13 spaced apart. The filter element 20 is movably disposed to move to a first filtering position opposite to the first connecting port 11 or a second filtering position opposite to the second connecting port 12. The sealing structure 30 is disposed at the air duct notch 13, and the sealing portion of the sealing structure 30 is made of a deformable material. The sealing structure 30 has a sealing state that covers at least a portion of the air duct notch 13 and a clearance state that allows at least a portion of the sealing portion to avoid the air duct notch 13. Specifically, when the filter element 20 is in the first filtering position, the filter element 20 is disposed to avoid the air duct notch 13, and the sealing structure 30 is in a sealed state; when the filter element 20 is in the second filtering position, the filter element 20 passes through the air duct notch 13 and contacts the sealing portion, so that the sealing structure 30 is in a clearance state.

[0054] Using the duct component provided in this embodiment, when the filter element 20 is in the first filtration position, the sealing structure 30 is in a sealed state, which can effectively seal the duct gap 13 to reduce air leakage and thus reduce the impact on the air volume. When the filter element 20 is in the second filtration position, the filter element 20 passes through the duct gap 13 and contacts the sealing part, so that the sealing structure 30 is in a clearance state. In this way, the deformation of the sealing part can facilitate the filter element 20 to pass through and achieve the sealing effect of blocking the duct gap 13 as much as possible through the contact between the filter element 20 and the sealing part, avoiding the sealing part from being fully opened and causing air leakage, thereby reducing the impact on the air volume. Therefore, the air duct component provided in this embodiment can reduce air leakage regardless of whether the filter element 20 is in the first or second filter position. This solves the technical problem in the prior art where changes in the filter position can affect the airflow of the indoor unit. Furthermore, it solves the problems of heat exchange airflow loss and condensation caused by air leakage, achieving a sealed performance of the air duct housing 10, ensuring no loss of heat exchange airflow, and improving the energy efficiency and user comfort of the air conditioner. The air duct component in this embodiment is not only suitable for household air conditioners but also for commercial and industrial air conditioning applications.

[0055] It should be noted that "the sealing structure 30 has a sealing state that covers at least part of the air duct gap 13" can be understood as follows: when the sealing structure 30 is in a sealed state, the sealing structure 30 covers most of the air duct gap 13. In this case, even if air leaks, it will not have a significant impact on the air volume. Alternatively, when the sealing structure 30 is in a sealed state, the sealing structure 30 covers the entire air duct gap 13. This can better improve the sealing performance of the air duct gap 13 and better achieve the technical effect of reducing air leakage.

[0056] Specifically, during the movement of the filter element 20 from the first filtering position to the second filtering position, the filter element 20 will contact the sealing portion and push the sealing portion to move, so that the sealing structure 30 is in the avoiding state.

[0057] In one embodiment, when the sealing structure 30 is in the sealing state, the sealing portion overlaps at the air duct gap 13 to facilitate better sealing of the air duct gap 13. In this structure, the filter element 20 will directly contact the sealing portion and push the sealing portion to deform during movement to make the sealing structure 30 in the avoiding state. Alternatively, when the sealing structure 30 is in the sealing state, the sealing portion is spaced apart from the air duct gap 13 to form an avoiding gap 35, so that the air duct gap 13 can be sealed. It should be noted that the size of the avoiding gap 35 is small, so the influence on the air leakage is small. In the above structure, the filter element 20 will enter the avoiding gap 35 during movement and push the sealing portion to deform to make the sealing structure 30 in the avoiding state. The above setting can facilitate the smooth movement of the filter element 20 and avoid the situation that the filter element 20 is blocked during movement.

[0058] In the embodiment, the sealing structure 30 comprises a first sealing piece 31 and a second sealing piece 32, a first connecting portion 311 of the first sealing piece 31 is connected or overlapped with one side of the air duct gap 13, and a second connecting portion 321 of the second sealing piece 32 is connected or overlapped with the other side of the air duct gap 13; a first sealing portion 312 of the first sealing piece 31 is located at the side of the first connecting portion 311 close to the second sealing piece, and a second sealing portion 322 of the second sealing piece is located at the side of the second connecting portion 321 close to the first sealing piece 31. When the sealing piece is in a sealing state, the first sealing portion 312 is overlapped with the second sealing portion 322, or the first sealing portion 312 and the second sealing portion 322 are arranged in splicing, or the first sealing portion 312 and the second sealing portion 322 are arranged in a spaced manner to form an avoiding gap 35. With such a structure, the air duct gap 13 can be effectively sealed when the sealing structure 30 is in a sealing state, and the filter piece 20 can be smoothly moved to an avoiding state to make the filter piece 20 smoothly move to a second filtering state. In addition, the above structure is compact, and can be deformed under the action of the filter piece 20 and the first sealing portion 312 and the second sealing portion 322 located on both sides of the filter piece 20, so as to ensure the sealing performance of the filter piece 20 on both sides to a certain extent, thereby reducing air leakage.

[0059] Specifically, the sealing structure 30 further comprises a first connecting piece 33 and a second connecting piece 34, the first connecting piece 33, the first connecting portion 311, the second connecting piece 34 and the second connecting portion 321 are sequentially and first connected to form a mounting port opposite to the air duct gap 13. With such a structure, the sealing structure 30 can be integrally formed for easy installation.

[0060] Specifically, the first connecting piece 33 and the second connecting piece 34 are located at the periphery of the air duct gap 13, so as to better avoid blocking the air duct gap 13, and make the filter piece 20 smoothly inserted into or withdrawn from the air duct gap 13.

[0061] In the embodiment, the sealing structure 30 is an integrally formed structure, so as to facilitate production and reduce production cost.

[0062] Specifically, the first connecting piece 33, the first connecting portion 311, the second connecting piece 34 and the second connecting portion 321 are made of hard plastic, so as to improve the stability of the connection and installation with the air duct shell 10.

[0063] Specifically, the first connecting part 311 and the second connecting part 321 are connected with the air duct shell 10 through locking pieces, which can be screws 100.

[0064] Specifically, the first sealing part 312 and the second sealing part 322 are made of rubber material, so that the first sealing part 312 and the second sealing part 322 can be deformed.

[0065] In the embodiment, the air duct shell 10 surrounds an air cavity which is in communication with the first communication port 11, the second communication port 12 and the air duct gap 13, and the sealing structure 30 is installed on the side of the air duct shell 10 away from the air cavity. With such a structure, the sealing structure 30 can be conveniently installed, disassembled and maintained, and the structure in the air cavity is also avoided from being interfered and affected.

[0066] Specifically, the sealing structure 30 can also be installed on the side of the air duct shell 10 close to the air cavity, so as to avoid interference and influence on the structure outside the air cavity.

[0067] In the embodiment, the air duct component further comprises an evaporator 40, which is arranged on both ends of the first communication port 11; when the filter 20 is in the first filtering position, the filter 20 is located on the side of the evaporator 40 away from the first communication port 11. With such a structure, the filter 20 can also effectively protect the evaporator 40, so as to avoid dust accumulation on the evaporator 40.

[0068] When the filter 20 is in the second filtering position, the filter 20 is overlapped on the part of the air duct shell 10 located at the second communication port 12, so that the second communication port 12 can be conveniently sealed, and dust can be prevented from entering the air cavity surrounded by the air duct shell 10, thereby effectively avoiding dust accumulation in the air duct shell 10.

[0069] In the embodiment, the filter 20 is in an arc shape, so as to conveniently move the filter 20 to the first filtering position or the second filtering position.

[0070] Specifically, the filter 20 is rotatably arranged.

[0071] Specifically, the air duct component further comprises a driving member 50, which is drivingly connected with the filter 20, so as to drive the filter 20 to move to the first filtering position or the second filtering position. Specifically, the driving member 50 is a driving gear, the filter 20 comprises a filter frame and a filter screen, the filter screen is installed on the filter frame, and a plurality of driven teeth on the filter frame are matched with driving teeth on the driving gear, so as to drive the filter 20 to move to the first filtering position or the second filtering position under the cooperation of the driving teeth and the driven teeth.

[0072] Specifically, the air duct component further comprises a fan blade 90 arranged in the air cavity, and the fan blade 90 can be a cross-flow fan blade.

[0073] The sealing structure 30 is composed of two parts of materials, the first connecting part 311, the first connecting member 33, the second connecting part 321 and the second connecting member 34 are surrounded to form a hard plastic frame, providing structural strength and positioning support; the first sealing part 312 and the second sealing part 322 in the middle are made of soft rubber material, and an avoidance gap 35 is formed between the first sealing part 312 and the second sealing part 322 (the avoidance gap 35 can be a strip-shaped gap suitable for the shape of the filter element 20, and can be an elongated slit). The elasticity of the soft rubber enables it to automatically adjust the sealing state according to the position change of the filter element 20.

[0074] The hard plastic frame is made of hard plastic such as hard plastic similar to ABS material, and a plurality of screw 100 fixing structures are provided on the hard plastic at appropriate positions, and the sealing plate is fixed on the air duct through the screw 100. After being fixed, the sealing structure 30 covers the gap of the air duct through which the filter screen device runs; the first sealing part 312 and the second sealing part 322 are made of soft rubber such as soft rubber similar to TPV material, and the avoidance gap 35 is formed between the first sealing part 312 and the second sealing part 322.

[0075] When the filter element 20 needs to pass through the air duct gap 13, the soft rubber part is extruded, the internal elongated slit is stretched, allowing the filter screen to pass through, while the elasticity of the rubber is used to minimize the air leakage caused thereby. When the filter element 20 does not need to pass through the air duct gap 13, the soft rubber part returns to the original state, the elongated slit is closed, and the hard plastic frame and the soft rubber part together form a tight sealing structure 30, effectively preventing air leakage and avoiding condensation.

[0076] The sealing structure 30 can be integrally formed by using double-color injection molding technology, which not only ensures the integrity of the structure but also simplifies the manufacturing process; alternatively, the hard plastic frame and the soft rubber part can be manufactured separately and then assembled to meet different production needs.

[0077] The embodiment two of the utility model provides a kind of air conditioner indoor unit, including indoor unit shell body 60 and the air duct component provided in above embodiment, indoor unit shell body 60 has the first air port 61 and second air port 62 of interval arrangement.The air duct component is arranged in indoor unit shell body 60, and the first communication port 11 of air duct component is communicated with the first air port 61, and the second communication port 12 of air duct component is communicated with the second air port 62.Such structure is arranged, it can be convenient to realize the first air port 61 of air conditioner indoor unit and the second air port 62 of air conditioner indoor unit, and the first air port 61 of air conditioner indoor unit is in the first air outlet state (corresponding to heating operation mode) of air outlet, corresponding to filter piece 20 is in the first filter position;It can also realize the second air port 62 of air conditioner indoor unit and the first air port 61 of air conditioner indoor unit, and the second air port 62 of air conditioner indoor unit is in the second air outlet state (corresponding to refrigeration operation mode) of air outlet, corresponding to filter piece 20 is in the second filter position.

[0078] Specifically, the first air port 61 can be arranged above the second air port 62, the first communication port 11 is located above the second communication port 12, and the air duct gap 13 is located between the first communication port 11 and the second communication port 12.

[0079] In the embodiment, the air conditioner indoor unit further includes a first air deflector 71, which is arranged at the first air port 61 in an openable and closable manner to realize opening or closing of the first air port 61.

[0080] In the embodiment, the air conditioner indoor unit further includes a second air deflector 72, which is arranged at the second air port 62 in an openable and closable manner to realize opening or closing of the second air port 62.

[0081] In the embodiment, the air conditioner indoor unit further includes a first air sweeping piece 81, which is movably arranged at the first air port 61; when the filter piece 20 is in the first filter position, the first air sweeping piece 81 is located on a side of the filter piece 20 away from the first communication port 11. In this way, it is convenient to ensure that the first air sweeping piece 81 has sufficient air sweeping space and to ensure air sweeping effect.

[0082] In the embodiment, the air conditioner indoor unit further includes a second air sweeping piece 82, which is movably arranged at the second air port 62; when the filter piece 20 is in the second filter position, the second air sweeping piece 82 is located on a side of the filter piece 20 away from the second communication port 12. In this way, it is convenient to ensure that the second air sweeping piece 82 has sufficient air sweeping space and to ensure air sweeping effect.

[0083] Specifically, the air conditioner indoor unit further includes a heating piece 110, which is arranged on a side of the evaporator 40 close to the first communication port 11.

[0084] Specifically, in the cooling mode, air enters from the second air outlet 62 and exits from the first air outlet 61 under the action of the air duct component. At this time, the filter 20 moves to the second filtering position to filter the air entering from the second air outlet 62.

[0085] In the heating mode, air enters from the first air outlet 61 and exits from the second air outlet 62 under the action of the air duct component. At this time, the filter 20 of the utility model moves to the first filtering position to filter the air entering from the first air outlet 61.

[0086] The filter 20 adopts a unique arc-shaped design. The filter 20 is driven by the motor to move smoothly along the preset arc-shaped track in the up-down direction.

[0087] When in the cooling mode, the filter 20 of the utility model moves to the second filtering position and passes through the air duct shell 10. An air duct gap 13 is formed on the wall of the air duct for the filter screen device of the air conditioner. After the filter 20 is moved to the position, a gap is formed between the filter screen and the air duct gap 13 to ensure the running clearance, so that part of the airflow passes through the air duct gap 13 when the heat exchange airflow passes through, which affects the total amount of upward airflow and the air volume and performance in the cooling mode.

[0088] When in the heating mode, the filter 20 of the utility model moves to the first filtering position and leaves the air duct. At this time, since the air duct gap 13 is formed on the wall of the air duct, if the sealing structure 30 is not blocked, part of the airflow will pass through the air duct gap 13 when the heat exchange airflow passes through, which affects the total amount of downward airflow and the air volume and performance in the heating mode.

[0089] Specifically, the sealing structure 30 is fixed at the air duct gap 13 by a plurality of screws 100, so that the sealing structure 30 covers the gap of the air duct.

[0090] When in the cooling mode, the filter 20 passes through the elongated slot (corresponding to the filtering gap) formed in the soft rubber (both the first sealing part 312 and the second sealing part 322 are made of soft rubber) of the middle part of the sealing structure 30 and moves to the predetermined position. At this time, the soft rubber of the sealing plate is in the open state, and since the rubber part has good elasticity, it can better fit the filter 20, so that the air duct gap 13 is better sealed.

[0091] When in the heating operation state, the filter piece 20 is operated to the upper side, and does not pass through the sealing structure 30, at this time, the first sealing part 312 and the second sealing part 322 are in the original state, at this time, the sealing structure 30 plays a role of shielding the air duct gap 13, preventing the heat exchange airflow from flowing out, and also has the effect of heat preservation to prevent the generation of condensate water.

[0092] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects: improve the sealing performance: through the elastic self-adaptive characteristics of the soft rubber, effective sealing of the filter screen device in different working modes is realized, air leakage and condensation problems are significantly reduced, and the energy efficiency and use environment comfort of the air conditioner are improved.

Improve user experience: solve the problems of air conditioner energy efficiency decline and use environment deterioration caused by air leakage and condensation, and improve the user's use satisfaction.
