Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to an air duct assembly for an air conditioner and an air conditioner. Background Art

[0002] Air conditioners are appliances that regulate indoor temperature and humidity. Fresh air air conditioners add a fresh air function to air conditioners, drawing fresh air indoors through a fresh air duct. The fresh air duct is a circular tube connected to the indoor unit at one end and to the outdoors at the other. This requires an additional hole in the wall to allow the circular fresh air duct to extend outdoors.

[0003] A related art fresh air air conditioner has a fresh air duct connected to its indoor unit. The duct has a semicircular cross-section. When the semicircular duct passes through a wall hole, it and the refrigerant pipe of the fresh air conditioner pass through the same hole, reducing the risk of interference. This reduces the number of holes required, making installation more convenient and cost-effective.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] The adaptation and connection of the semi-circular fresh air duct to the air conditioner indoor unit is more difficult, and the joints and interfaces need to be redesigned, which results in high production costs.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0040] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0041] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0042] Combine Figure 1-2 As shown, an embodiment of the present disclosure provides an air duct assembly for an air conditioner, comprising: a circular tube segment 100, an elliptical tube segment 200, and a transition segment 300. The flow rate of the elliptical tube segment 200 is greater than or equal to the flow rate of the circular tube segment 100; the transition segment 300 is located between the circular tube segment 100 and the elliptical tube segment 200, with one end communicating with the circular tube segment 100 and adapting to the shape of the circular tube segment 100, and the other end communicating with the elliptical tube segment 200 and adapting to the shape of the elliptical tube segment 200, and the cross-section of the transition segment 300 gradually changes along its axial direction.

[0043] The air duct assembly for an air conditioner provided by the disclosed embodiments can be assembled and used in the air conditioner, with the circular tube segment 100 connected to the air conditioner's indoor unit and the elliptical tube segment 200 extending through a wall hole to the outdoors. The elliptical tube segment 200 has a relatively narrow short axis, which reduces the space occupied radially along the wall hole. This provides room for the air conditioner's refrigerant pipes and wiring harnesses to be routed through the wall hole, reducing the risk of interference between the elliptical tube segment 200 and the refrigerant pipes and wiring harnesses. Furthermore, the circular tube segment 100 has a relatively regular shape, making connection to the air conditioner's indoor unit relatively easy, eliminating the need to redesign joints and interfaces, and reducing production costs.

[0044] Optionally, the flow rate of the elliptical tube segment 200 is equal to 1.1 times the flow rate of the circular tube segment 100. In this way, the flow rate of the elliptical tube segment 200 is greater than the flow rate of the circular tube segment 100, making the flow of the air flow smoother.

[0045] Optionally, the circular tube section 100, the transition section 300 and the elliptical tube section 200 are partially or entirely made of polyethylene. Thus, the circular tube section 100, the transition section 300 and the elliptical tube section 200 made of polyethylene have good aging resistance.

[0046] Illustratively, the circular tube segment 100 or the transition segment 300 or the elliptical tube segment 200 is made of polyethylene material; or the circular tube segment 100 and the transition segment 300 are both made of polyethylene material, or the circular tube segment 100, the transition segment 300 and the elliptical tube segment 200 are all made of polyethylene material.

[0047] Optionally, some or all of the circular tube section 100, transition section 300, and elliptical tube section 200 may be threaded hoses. This provides relatively high structural strength. When the circular tube section 100, transition section 300, and elliptical tube section 200 are threaded hoses, the risk of pipe deformation is reduced, ensuring adequate airflow. Threaded hoses are also easy to bend, making pipe routing more convenient during air conditioner installation.

[0048] Illustratively, the round tube segment 100 or the transition segment 300 or the elliptical tube segment 200 is a threaded hose; or the round tube segment 100 and the transition segment 300 are all threaded hoses, or the round tube segment 100, the transition segment 300 and the elliptical tube segment 200 are all threaded hoses.

[0049] Optionally, the circular tube segment 100 and the transition segment 300 are integrally formed, or the elliptical tube segment 200 and the transition segment 300 are integrally formed, or the circular tube segment 100, the transition segment 300, and the elliptical tube segment 200 are integrally formed. In this way, when the circular tube segment 100 and the transition segment 300 are integrally formed, the elliptical tube segment 200 and the transition segment 300 are integrally formed, or the circular tube segment 100, the transition segment 300, and the elliptical tube segment 200 are integrally formed, the strength of the connection can be increased and the risk of air leakage between the pipes can be reduced.

[0050] Combine Figure 3 and Figure 4 As shown, optionally, an adapter 400 is sleeved on the outer side of one end of the circular tube section 100 facing away from the transition section 300. In this way, the adapter 400 facilitates connection with the indoor unit of the air conditioner, thereby improving the stability of the connection between the circular tube section 100 and the indoor unit of the air conditioner.

[0051] Optionally, the adapter 400 is made of polyethylene material. Thus, the adapter 400 made of polyethylene material has good aging resistance.

[0052] Optionally, the inner side wall of the adapter 400 is threadedly connected to the outer side wall of the round pipe section 100. In this way, the connection between the adapter 400 and the round pipe section 100 is more stable, reducing the risk of the adapter 400 and the round pipe section 100 being separated.

[0053] Optionally, a side wall of the adapter 400 is flush with the end surface of the circular tube section 100 facing away from the transition section 300. In this way, when the adapter 400 is connected to the air conditioner indoor unit, the circular tube section 100 does not protrude from a side wall of the adapter 400, reducing the risk of interference between the circular tube section 100 and the air conditioner indoor unit.

[0054] Combine Figure 5As shown, optionally, the adapter 400 includes a support ring 410 and a connecting plate 420. The support ring 410 is provided with a snap-fit ​​portion 430. The connecting plate 420 is fixedly mounted on one side of the support ring 410 and located inside the snap-fit ​​portion 430. The connecting plate 420 is rotatably connected to the outer wall of the circular tube segment 100. When the air duct assembly for an air conditioner is assembled and used in the air conditioner, the snap-fit ​​portion 430 snaps into engagement with the air conditioner's indoor unit. Thus, the rotatable connection between the connecting plate 420 and the outer wall of the circular tube segment 100 increases the connection and contact area, improves the connection stability, and reduces the risk of the connecting plate 420 detaching from the circular tube segment 100. Furthermore, the snap-fit ​​portion 430 snaps into engagement with the air conditioner's indoor unit, making installation and removal more convenient and more efficient.

[0055] Specifically, the connecting plate 420 is threadedly connected to the outer wall of the round pipe section 100. In this way, the area of ​​the connection contact is relatively large and the stability of the connection is higher.

[0056] Optionally, one end of the connecting plate 420 is flush with the end surface of the circular tube segment 100 facing away from the transition section 300, and the other end of the connecting plate 420 is fixedly connected to the support ring 410. In this way, when the adapter 400 is connected to the air conditioner indoor unit, the circular tube segment 100 does not protrude from a side wall of the connecting plate 420, reducing the risk of interference between the circular tube segment 100 and the air conditioner indoor unit.

[0057] Combine Figure 6 As shown, the clamping portion 430 is optionally a clamping plate 431 that is fixedly connected to the support ring 410. The clamping plate 431 extends axially along the circular tube segment 100, and a clamping hole 432 is defined on one end of the clamping plate 431 facing away from the support ring 410. When the air duct assembly for an air conditioner is assembled and used in the air conditioner, the clamping hole 432 is clamped to the indoor unit of the air conditioner. Thus, the clamping hole 432 is used to clamp the indoor unit of the air conditioner, making connection and removal more convenient and more efficient.

[0058] Optionally, multiple clamping plates 431 are provided, and multiple clamping plates 431 are provided along the circumference of the support ring 410. In this way, the multiple clamping plates 431 and the multiple clamping holes 432 are connected to the indoor unit of the air conditioner, and the connection position is increased, and the connection strength is increased, thereby reducing the risk of the clamping plates 431 being separated from the indoor unit of the air conditioner.

[0059] Optionally, a plug-in slot 433 is defined between the card plate 431 and the connecting plate 420. In this way, when the card plate 431 is connected to the indoor unit of the air conditioner, the plug-in slot 433 provides plugging and guidance for the protruding docking portion of the indoor unit, making installation more convenient.

[0060] Combine Figure 7As shown, optionally, an edge plate 434 protruding from the clamping plate 431 is provided at the edge of the clamping hole 432. In this way, the hole wall area of ​​the clamping hole 432 is increased, thereby increasing the contact area between the hole wall of the clamping hole 432 and the indoor unit of the air conditioner, thereby increasing the stability of the connection with the indoor unit of the air conditioner.

[0061] Optionally, the engaging hole 432 includes a first hole portion 4321 and a second hole portion 4322. The first hole portion 4321 extends from the end of the engaging plate 431 facing away from the support ring 410 toward the support ring 410; the second hole portion 4322 communicates with the end of the first hole portion 4321 facing the support ring 410, and the first hole portion 4321 and the second hole portion 4322 are arranged perpendicularly. In this way, the portion of the air conditioner's indoor unit that interfaces with the engaging hole 432 can be installed into the second hole portion 4322 along the first hole portion 4321. Since the second hole portion 4322 engages with the air conditioner's indoor unit and the first hole portion 4321 and the second hole portion 4322 are arranged perpendicularly, the risk of the second hole portion 4322 detaching from the air conditioner's indoor unit is reduced.

[0062] Optionally, the width of the second hole portion 4322 at one end facing away from the first hole portion 4321 is greater than the width of the other end. This allows the portion of the air conditioner's indoor unit that interfaces with the latching hole 432 to be installed within the second hole portion 4322 along the first hole portion 4321. This allows for relative displacement from the narrower portion of the second hole portion 4322 to the wider portion, creating a wider fit and facilitating installation. Displacing the second hole portion 4322 from the wider portion toward the narrower portion requires greater effort, reducing the risk of the second hole portion 4322 becoming detached from the air conditioner's indoor unit.

[0063] Specifically, the edge of the first hole portion 4321 and / or the edge of the second hole portion 4322 are both provided with an edge plate 434 that protrudes from the clamping plate 431. This increases the hole wall area of ​​the first hole portion 4321 and / or the second hole portion 4322, thereby increasing the contact area between the hole wall of the second hole portion 4322 and the indoor unit of the air conditioner, thereby increasing the stability of the connection with the indoor unit of the air conditioner.

[0064] Optionally, an extension plate 440 is provided on the same side of the support ring 410 as the clamping plate 431, and both ends of the extension plate 440 are connected to one clamping plate 431. In this way, the strength of the connection between the support ring 410, the extension plate 440 and the clamping plate 431 is increased.

[0065] Optionally, two extension plates 440 are provided, so as to further increase the strength of the connection between the support ring 410 , the extension plates 440 and the clamping plate 431 .

[0066] Optionally, the middle portion of the extension plate 440 projects beyond the rest of the extension plate 440, facing away from the support ring 410. Thus, when the clip plate 431 is connected to the indoor unit of the air conditioner, the extension plate 440 and the protruding portion of the extension plate 440 abut against the indoor unit of the air conditioner, resulting in a larger abutment area and a more stable connection.

[0067] Optionally, multiple connecting plates 420 are provided, and the multiple connecting plates 420 are evenly connected to the edge of the inner ring hole of the support ring 410. In this way, through the rotational connection of the multiple connecting plates 420 with the outer wall of the circular tube segment 100, the connection and contact area is further increased, the stability of the connection is further improved, and the risk of the connecting plates 420 being separated from the circular tube segment 100 is reduced.

[0068] It can be understood that the inner wall of each connecting plate 420 is threadedly connected to the outer wall of the round pipe section 100 .

[0069] Specifically, there are two connecting plates 420. In this way, the two connecting plates 420 are rotatably connected to the outer wall of the circular tube segment 100, the connection and contact area is relatively large, the stability of the connection is relatively high, and the risk of the connecting plate 420 being separated from the circular tube segment 100 is reduced.

[0070] Optionally, two clamping plates 431 are provided, and the two connecting plates 420 and the two clamping plates 431 are alternately arranged along the circumference of the support ring 410. In this way, the clamping holes 432 are used to clamp the indoor unit of the air conditioner, which increases the stability of the clamping, facilitates connection and removal, and improves efficiency.

[0071] Optionally, the length of the circular tube segment 100 is greater than or equal to 400 mm and less than or equal to 700 mm. Thus, when the length of the circular tube segment 100 is less than 400 mm, the length of the circular tube segment 100 is relatively too short. When the circular tube segment 100 is connected to the indoor unit of the air conditioner, since the circular tube segment 100 needs to extend into the outer casing of the indoor unit of the air conditioner and communicate with the fresh air module of the indoor unit of the air conditioner, the circular tube segment 100 is too short, and the risk of the transition section 300 and the elliptical tube segment 200 interfering with the outer casing of the indoor unit of the air conditioner is relatively high. When the length of the circular tube segment 100 is greater than 700 mm, the length of the circular tube segment 100 is relatively too long. Since the elliptical tube segment 200 needs to pass through the wall hole and extend out of the wall, the circular tube segment 100 is too long, and the distance between the indoor unit of the air conditioner and the wall hole is relatively close, the excessively long portion of the circular tube segment 100 needs to be coiled indoors, which has a greater risk of being exposed and has poor integrity. It can be seen that the length of the circular tube section 100 is greater than or equal to 400 mm and less than or equal to 700 mm, which is more reasonable, reducing the risk of interference between the transition section 300 and the elliptical tube section 200 and the casing of the air conditioner indoor unit, and also reducing the risk of the circular tube section 100 being exposed.

[0072] Optionally, the length of the circular tube section 100 is equal to 640 mm. In this way, the risk of the transition section 300 and the elliptical tube section 200 interfering with the housing of the air conditioner indoor unit is reduced, and the risk of the circular tube section 100 being exposed is also reduced.

[0073] Combine Figure 8 and Figure 9 As shown, a rigid tube 500 is optionally sleeved on the end of the elliptical tube segment 200 facing away from the transition segment 300. The rigid tube 500 matches the shape of the elliptical tube segment 200. This ensures that the shape of the rigid tube 500 matches that of the elliptical tube segment 200, and by inserting the rigid tube 500 into the wall hole, it is more convenient to extend the pipe from indoors to outdoors. When the rigid tube 500 shares the same wall hole as the refrigerant pipe and wiring harness, the rigid tube 500's high hardness reduces the risk of deformation caused by the refrigerant pipe and wiring harness, ensuring effective ventilation within the duct.

[0074] Optionally, the hard tube 500 is made of PVC (polyvinyl chloride) material. In this way, the hard tube 500 made of PVC material has relatively high hardness and relatively good anti-aging performance.

[0075] Specifically, the hard tube 500 is inserted into the elliptical tube section 200, and the outer wall of the hard tube 500 abuts the inner wall of the elliptical tube section 200. In this way, the contact area between the hard tube 500 and the elliptical tube section 200 is relatively large, the connection is more stable, and it is not easy to fall off.

[0076] Optionally, an elastic sealing layer 600 is provided between the rigid tube 500 and the elliptical tube section 200. Thus, when the rigid tube 500 and the elliptical tube section 200 are connected, the elastic sealing layer 600 fills the gap between the rigid tube 500 and the elliptical tube section 200, reducing the risk of air leakage between the rigid tube 500 and the elliptical tube section 200. This also increases the stability of the connection between the rigid tube 500 and the elliptical tube section 200, making it less likely to fall off.

[0077] Optionally, the elastic sealing layer 600 is made of a rubber material. In this way, the elastic sealing layer 600 made of a rubber material has high elasticity and can be well filled between the hard tube 500 and the elliptical tube section 200.

[0078] In some embodiments, an air conditioner includes: an air duct assembly for an air conditioner as described in the above embodiment.

[0079] The air conditioner provided by the disclosed embodiment includes the air duct assembly for an air conditioner according to the above-described embodiment. When the air duct assembly for an air conditioner is assembled and used in the air conditioner, the circular tube segment 100 is connected to the air conditioner indoor unit, and the elliptical tube segment 200 extends through the wall hole to the outside. The elliptical tube segment 200 has a relatively narrow short axis, which reduces the space occupied in the radial direction of the wall hole, providing space margin for the air conditioner's refrigerant pipe and wiring harness to be routed through the wall hole, and reducing the risk of interference between the elliptical tube segment 200 and the refrigerant pipe and wiring harness. Furthermore, the circular tube segment 100 has a relatively regular shape, making connection to the air conditioner indoor unit relatively easy, avoiding the need to redesign joints and interfaces, and reducing production costs.
