Abstract

The utility model relates to the technical field of household appliances, and discloses an air pipe assembly which comprises an indoor air pipe and an oval through-wall pipe. The oval through-wall pipe is connected with one end of the indoor air pipe in a sleeved mode, and the end of the indoor air pipe is matched with the oval through-wall pipe in shape. In the utility model, under the condition that the elliptical through-wall pipe penetrates through the wall hole, the short shaft part of the elliptical through-wall pipe is relatively narrow, so that the occupation of the upward space of the wall hole is reduced, and space allowance is provided for a refrigerant pipe and a wire harness of an air conditioner to penetrate through the wall hole. Under the condition that the refrigerant pipe and the oval through-wall hole share the same wall hole, the risk that the oval through-wall pipe is extruded and deformed by the refrigerant pipe and the wire harness is reduced, and the risk that the excess flow of the oval through-wall pipe is reduced is small. The invention further discloses the air conditioner.

Description

Technical Field

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

[0002] Air conditioners are appliances that regulate indoor temperature and humidity. Fresh air air conditioners are air conditioners that add a fresh air function. Fresh air air conditioners draw fresh air from outside into the home through a fresh air duct. One end of the duct connects to the indoor unit, while the other extends through a wall hole to connect to the outside. However, fresh air air conditioners require 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] Since the refrigerant pipe and the fresh air duct share the same wall hole, and the refrigerant pipe is easily bent and deformed during the wall penetration process, squeezing the fresh air duct, there is a greater risk of reduced flow rate of the fresh air duct.

[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. Utility Model Content

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0012] Optionally, a plurality of elastic plug-in rods are provided on the elliptical disc-shaped net, a plurality of plug-in holes are provided at the end of the elliptical wall-penetrating tube, and each elastic plug-in rod is plugged into a corresponding plug-in hole.

[0013] Optionally, an anti-slip protrusion is provided on the outer side wall of the elliptical wall-penetrating tube.

[0014] Optionally, the indoor air duct includes a circular tube and an elliptical tube, wherein one end of the elliptical tube is connected to the air duct and the other end is sleeved with the elliptical wall-penetrating tube.

[0015] Optionally, a sealing member is provided in the gap between the elliptical wall-penetrating tube and the indoor air duct.

[0016] Optionally, an adapter is provided at one end of the indoor air duct facing away from the elliptical wall-penetrating tube.

[0017] Optionally, the adapter includes a support ring and a connecting plate. The support ring is sleeved onto the outer side of the end of the indoor air duct and is provided with a clamping portion. The connecting plate is fixedly mounted on one side of the support ring and located inside the clamping portion. The connecting plate is rotatably connected to the outer wall of the indoor air duct. When the air duct assembly is assembled and used in an air conditioner, the clamping portion is clamped to the indoor unit of the air conditioner.

[0018] In some embodiments, an air conditioner includes: an air duct assembly as described in the above embodiment.

[0019] The air duct assembly and air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0020] When an elliptical wall-penetrating pipe passes through a wall hole, the short axis of the pipe is relatively narrow, reducing the space occupied in the radial direction of the wall hole and providing additional space for the air conditioner's refrigerant pipe and wiring harness to pass through the wall hole. This reduces the risk of the refrigerant pipe and wiring harness being squeezed and deformed by the pipe, even when the refrigerant pipe and wiring harness share the same wall hole, minimizing the risk of reduced flow rate through the pipe.

[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 As shown, the embodiment of the present disclosure provides an air duct assembly, comprising: an indoor air duct 100 and an elliptical wall-penetrating tube 200. The elliptical wall-penetrating tube 200 is sleeved with one end of the indoor air duct 100, and the shape of the end of the indoor air duct 100 is adapted to that of the elliptical wall-penetrating tube 200.

[0043] The duct assembly provided by the disclosed embodiments allows the elliptical wall-penetrating tube 200 to be relatively narrow along its minor axis when passing through a wall hole. This reduces the space occupied radially by the wall hole and provides additional space for the air conditioner's refrigerant pipe and wiring harness to be routed through the wall hole. This reduces the risk of the refrigerant pipe and wiring harness squeezing and deforming the elliptical wall-penetrating tube 200, even when the refrigerant pipe and wiring harness share the same wall hole, minimizing the risk of reduced flow through the elliptical wall-penetrating tube 200.

[0044] It can be understood that one end of the indoor air duct 100 is connected to the indoor unit of the air conditioner, and the other end of the indoor air duct 100 is connected to the elliptical wall-penetrating pipe 200.

[0045] Combine Figure 2 、 Figure 3 and Figure 4 As shown, a protective member 300 is optionally provided at the end of the elliptical wall-penetrating tube 200 facing away from the indoor air duct 100. Thus, by providing the protective member 300, some foreign matter can be prevented from entering the end of the elliptical wall-penetrating tube 200 extending outside the wall, thereby reducing the risk of the elliptical wall-penetrating tube 200 being blocked and causing a decrease in the flow rate.

[0046] Optionally, the protective member 300 is an elliptical disc-shaped net 310, which is detachably connected to the elliptical wall tube 200. This allows the elliptical disc-shaped net 310 to conform to the shape of the elliptical wall tube 200, making them more compatible. Furthermore, the elliptical disc-shaped net 310 provides enhanced protection, reducing the risk of larger foreign objects entering the elliptical wall tube 200.

[0047] Optionally, the elliptical disc net 310 is provided with a plurality of elastic plug rods 320, and the end of the elliptical wall tube 200 is provided with a plurality of plug holes 210, with each elastic plug rod 320 plugged into a corresponding plug hole 210. This arrangement reduces the risk of the elliptical disc net 310 falling out of the elliptical wall tube 200, improves stability, and ensures the protective effectiveness of the elliptical disc net 310. The elastic plug rods 320 are flexible, making insertion and removal into and from the plug holes 210 more convenient.

[0048] Optionally, the elliptical disc net 310 and the plurality of elastic plug rods 320 are integrally formed. In this way, the strength of the connection between the elliptical disc net 310 and the plurality of elastic plug rods 320 is higher.

[0049] Optionally, the elliptical disc-shaped net 310 and a plurality of elastic plug-in rods 320 are all made of stainless steel. Like this, the elliptical disc-shaped net 310 and a plurality of elastic plug-in rods 320 made of stainless steel have better anti-oxidation effect and are more durable.

[0050] It is understandable that the elliptical disc mesh 310 can also be made of other materials such as plastic or carbon steel.

[0051] Specifically, there are two elastic plug rods 320 and two plug holes 210. In this way, the two elastic plug rods 320 are plugged into the two plug holes 210 to cooperate with each other, reducing the risk of the elliptical disc net 310 falling out of the elliptical wall tube 200, improving stability, and ensuring the protective effect of the elliptical disc net 310.

[0052] Specifically, the two plug holes 210 are arranged on opposite sides of the elliptical disc net 310. Like this, the two elastic plug rods 320 are plugged in the two plug holes 210, the span is larger, and the stability of plugging is higher.

[0053] Optionally, each elastic plug rod 320 extends away from the elliptical disc net 310 and toward the inside of the elliptical wall-penetrating tube 200. In this way, since the elliptical disc net 310 plays a protective role in preventing some foreign matter from entering the elliptical wall-penetrating tube 200, the elliptical disc net 310 needs to be as close as possible to the edge of the elliptical wall-penetrating tube 200 at the end facing the outdoors. For example, the plane where the elliptical disc net 310 is located coincides with the end face of the elliptical wall-penetrating tube 200. If the plug hole 210 is set at the edge of the elliptical wall-penetrating tube 200, the distance between the plug hole 210 and the end face of the elliptical wall-penetrating tube 200 is relatively close, the strength of the pipe between the plug hole 210 and the end face of the elliptical wall-penetrating tube 200 is relatively low, and the risk of rupture is relatively high. Therefore, each elastic plug rod 320 extends away from the elliptical disc net 310 toward the inside of the elliptical wall tube 200, and the distance between the plug hole 210 and the end facing the outdoor of the elliptical wall tube 200 is relatively far, and the pipe strength between the plug hole 210 and the end face of the elliptical wall tube 200 is relatively high.

[0054] Specifically, the axis of the plug end of each elastic plug rod 320 is perpendicular to the axis of the elliptical wall tube 200. Like this, the plug end of the elastic plug rod 320 is inserted into the plug hole 210 along the axial direction of the plug hole 210, and the strength of the connection is higher.

[0055] Combine Figure 5 As shown, an anti-slip protrusion 400 is optionally provided on the outer wall of the elliptical wall tube 200. Thus, when the elliptical wall tube 200 is inserted into the wall hole, the anti-slip protrusion 400 directly contacts the inner wall of the wall hole, reducing the risk of scratching the surface of the elliptical wall tube 200. The anti-slip protrusion 400 also increases the friction between the elliptical wall tube 200 and the wall of the wall hole, reducing the risk of the elliptical wall tube 200 falling out of the wall hole.

[0056] Optionally, the anti-slip protrusion 400 is a plurality of anti-slip rings 410 arranged axially along the elliptical wall-penetrating tube 200. In this manner, the anti-slip rings 410 directly contact the inner wall of the wall hole, reducing the risk of scratching the surface of the elliptical wall-penetrating tube 200. The anti-slip rings 410 also increase the friction between the elliptical wall-penetrating tube 200 and the wall of the wall hole, reducing the risk of the elliptical wall-penetrating tube 200 falling out of the wall hole.

[0057] Optionally, the anti-slip ring 410 is made of an elastic material. In this way, the anti-slip ring 410 has a certain elasticity, so that an elastic buffer is provided between the elliptical wall-penetrating tube 200 and the inner wall of the wall hole, and between the elliptical wall-penetrating tube 200 and the refrigerant pipe and the wiring harness.

[0058] It can be understood that the anti-slip ring 410 is made of elastic material such as rubber.

[0059] Optionally, a groove 220 is provided on the outer side wall of the elliptical wall-penetrating tube 200, and the anti-slip protrusion 400 is disposed in the groove 220. In this way, the risk of relative sliding between the anti-slip protrusion 400 and the elliptical wall-penetrating tube 200 is reduced.

[0060] Specifically, a plurality of grooves 220 are provided, and each anti-slip ring 410 is disposed in one groove 220 .

[0061] Specifically, there are five anti-slip rings 410 and five grooves 220 .

[0062] Combine Figure 6 As shown, the indoor air duct 100 optionally includes a circular tube 110 and an elliptical tube 120. One end of the elliptical tube 120 is connected to the air duct, and the other end is connected to the elliptical wall-penetrating tube 200. In this way, the circular tube 110 is connected to the indoor unit of the air conditioner, and the elliptical tube 120 is connected to the elliptical wall-penetrating tube 200, thereby connecting the indoor unit to the outdoors. The shape of the circular tube 110 is more compatible with the indoor unit.

[0063] Optionally, part or all of the circular tube 110 and the oval tube 120 are threaded hoses. In this way, the circular tube 110 and the oval tube 120 are easy to bend and easy to install, and the structural strength of the circular tube 110 and the oval tube 120 is relatively high.

[0064] Optionally, part or all of the circular tube 110 and the oval tube 120 are made of polyethylene. In this way, the circular tube 110 and the oval tube 120 made of polyethylene have good aging resistance.

[0065] Optionally, the flow rate of the oval tube 120 is greater than or equal to the flow rate of the circular tube 110. Thus, when the flow rate of the oval tube 120 is equal to the flow rate of the circular tube 110, the airflow between the two tubes is relatively smooth. When the flow rate of the oval tube 120 is greater than the flow rate of the circular tube 110, the airflow in the circular tube 110 flows more smoothly to the oval tube 120, and the risk of airflow loss in the event of a bend in the oval tube 120 is relatively small.

[0066] Optionally, a blocking member 500 is provided in the gap between the elliptical wall-penetrating tube 200 and the indoor air duct 100. In this way, the risk of air leakage between the elliptical wall-penetrating tube 200 and the indoor air duct 100 is reduced, and the air tightness is better.

[0067] Optionally, the blocking member 500 is an elastic sealing layer 510. Thus, the elastic sealing layer 510 has a certain elasticity, which facilitates the indoor air duct 100 to be sleeved on the elliptical wall-penetrating tube 200, and the elastic sealing layer 510 can better fill the gap between the elliptical wall-penetrating tube 200 and the indoor air duct 100.

[0068] Specifically, the elastic sealing layer 510 is made of rubber material.

[0069] Optionally, the elliptical wall-penetrating tube 200 is made of a hard material. In this way, when the elliptical wall-penetrating tube 200 shares the same wall hole with the refrigerant pipe and the wiring harness, the risk of the elliptical wall-penetrating tube 200 being squeezed and deformed is low, thereby ensuring the circulation effect of the airflow.

[0070] Combine Figure 7 、 Figure 8 and Figure 9 As shown, optionally, an adapter 600 is provided at one end of the indoor air duct 100 facing away from the elliptical wall-penetrating tube 200. In this way, the adapter 600 facilitates connection with the indoor unit of the air conditioner, thereby improving the stability of the connection between the indoor air duct 100 and the indoor unit of the air conditioner.

[0071] Optionally, when the round tube 110 is a threaded hose, the inner wall of the adapter 600 is threadedly connected to the outer wall of the round tube 110. In this way, the stability of the connection is relatively high, reducing the risk of the round tube 110 and the adapter 600 being separated.

[0072] Optionally, a side wall of the adapter 600 is flush with the end face of the circular tube 110 facing away from the oval tube 120. In this way, when the adapter 600 is connected to the air conditioner indoor unit, the circular tube 110 does not protrude from a side wall of the adapter 600, reducing the risk of interference between the circular tube 110 and the air conditioner indoor unit.

[0073] Optionally, the adapter 600 includes a support ring 610 and a connecting plate 620. The support ring 610 is sleeved onto the outer end of the indoor air duct 100 and is provided with a clamping portion 630. The connecting plate 620 is fixedly mounted on one side of the support ring 610 and located inside the clamping portion 630. The connecting plate 620 is pivotally connected to the outer wall of the indoor air duct 100. When the air duct assembly is assembled and used in an air conditioner, the clamping portion 630 is clamped to the air conditioner's indoor unit. This rotatable connection between the connecting plate 620 and the outer wall of the indoor air duct 100 increases the connection and contact area, improves the connection stability, and reduces the risk of the connecting plate 620 detaching from the indoor air duct 100. Furthermore, the clamping portion 630 is clamped to the air conditioner's indoor unit, making installation and removal more convenient and more efficient.

[0074] Specifically, when the round tube 110 is a threaded hose, the connecting plate 620 is threadedly connected to the outer wall of the round tube 110 .

[0075] Optionally, one end of the connecting plate 620 is flush with the end surface of the circular tube 110 facing away from the oval tube 120, and the other end of the connecting plate 620 is fixedly connected to the support ring 610. In this way, when the adapter 600 is connected to the air conditioner indoor unit, the circular tube 110 does not protrude from a side wall of the connecting plate 620, reducing the risk of interference between the circular tube 110 and the air conditioner indoor unit.

[0076] Optionally, the clamping portion 630 is a clamping plate 631 that is fixedly connected to the support ring 610. The clamping plate 631 extends axially along the circular tube 110, and a clamping hole 632 is defined at one end of the clamping plate 631 facing away from the support ring 610. When the air duct assembly for an air conditioner is assembled and used in the air conditioner, the clamping hole 632 is clamped to the air conditioner's indoor unit. Thus, the clamping hole 632 is used to clamp the air conditioner's indoor unit, making connection and removal more convenient and more efficient.

[0077] Optionally, multiple clamping plates 631 are provided, and multiple clamping plates 631 are provided along the circumference of the support ring 610. In this way, the multiple clamping plates 631 and the multiple clamping holes 632 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 631 being separated from the indoor unit of the air conditioner.

[0078] Optionally, a plug-in slot 633 is defined between the card plate 631 and the connecting plate 620. In this way, when the card plate 631 is connected to the indoor unit of the air conditioner, the plug-in slot 633 provides plugging and guidance for the protruding docking part of the indoor unit, making installation more convenient.

[0079] Optionally, an edge plate 634 protruding from the clamping plate 631 is provided at the edge of the clamping hole 632. In this way, the hole wall area of ​​the clamping hole 632 is increased, thereby increasing the contact area between the hole wall of the clamping hole 632 and the indoor unit of the air conditioner, thereby increasing the stability of the connection with the indoor unit of the air conditioner.

[0080] Optionally, the engaging hole 632 includes a first hole portion 6321 and a second hole portion 6322. The first hole portion 6321 extends from the end of the engaging plate 631 facing away from the support ring 610 toward the support ring 610; the second hole portion 6322 communicates with the end of the first hole portion 6321 facing the support ring 610, and the first hole portion 6321 and the second hole portion 6322 are arranged perpendicularly. In this way, the portion of the air conditioner's indoor unit that interfaces with the engaging hole 632 can be installed into the second hole portion 6322 along the first hole portion 6321. Since the second hole portion 6322 engages with the air conditioner's indoor unit and the first hole portion 6321 and the second hole portion 6322 are arranged perpendicularly, the risk of the second hole portion 6322 detaching from the air conditioner's indoor unit is reduced.

[0081] Optionally, the width of the second hole portion 6322 at one end facing away from the first hole portion 6321 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 632 to be installed within the second hole portion 6322 along the first hole portion 6321. This allows for relative displacement from the narrower portion of the second hole portion 6322 to the wider portion, creating a wider fit and facilitating installation. Displacing the second hole portion 6322 from the wider portion toward the narrower portion requires greater effort, reducing the risk of the second hole portion 6322 becoming detached from the air conditioner's indoor unit.

[0082] Specifically, the edge of the first hole portion 6321 and / or the edge of the second hole portion 6322 are both provided with an edge plate 634 that protrudes from the clamping plate 631. This increases the hole wall area of ​​the first hole portion 6321 and / or the second hole portion 6322, thereby increasing the contact area between the hole wall of the second hole portion 6322 and the indoor unit of the air conditioner, thereby increasing the stability of the connection with the indoor unit of the air conditioner.

[0083] Optionally, an extension plate 640 is provided on the same side of the support ring 610 as the clamping plate 631, and both ends of the extension plate 640 are connected to one clamping plate 631. In this way, the strength of the connection between the support ring 610, the extension plate 640 and the clamping plate 631 is increased.

[0084] Optionally, the middle portion of the extension plate 640 projects outward from the rest of the extension plate 640, facing away from the support ring 610. Thus, when the clamping plate 631 is connected to the indoor unit of the air conditioner, the extension plate 640 and the protruding portion of the extension plate 640 abut against the indoor unit of the air conditioner, resulting in a larger abutment area and a more stable connection.

[0085] Optionally, multiple connecting plates 620 are provided, and the multiple connecting plates 620 are evenly connected to the edge of the inner ring hole of the support ring 610. In this way, through the rotational connection of the multiple connecting plates 620 with the outer wall of the circular tube 110, the connection and contact area is further increased, the stability of the connection is further improved, and the risk of the connecting plates 620 being separated from the circular tube 110 is reduced.

[0086] It can be understood that when the round tube 110 is a threaded hose, the inner wall of each connecting plate 620 is threadedly connected to the outer wall of the round tube 110 .

[0087] Specifically, two connecting plates 620 are provided.

[0088] In some embodiments, an air conditioner includes: an air duct assembly as described in the above embodiment.

[0089] With the air conditioner provided by the disclosed embodiment, since it includes the air duct assembly of the aforementioned embodiment, when the elliptical wall-penetrating tube 200 is passed through a wall hole, the minor axis portion of the elliptical wall-penetrating tube 200 is relatively narrow, thereby reducing the space occupied in the radial direction of the wall hole and providing sufficient space for the air conditioner's refrigerant pipe and wiring harness to be passed through the wall hole. This reduces the risk of the elliptical wall-penetrating tube 200 being squeezed and deformed by the refrigerant pipe and wiring harness when the refrigerant pipe and the elliptical wall-penetrating tube share the same wall hole, thereby minimizing the risk of reduced flow rate of the elliptical wall-penetrating tube 200.

[0090] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations.
