Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, for example, to a component for connecting air ducts of an air conditioner 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, drawing fresh air indoors through a fresh air duct. One end of the fresh air duct is connected to the indoor unit, while the other end extends through a wall hole and connects to the outside. Depending on the installation location, the distance between the indoor unit and the outside varies. For larger distances, a new fresh air duct needs to be attached to the existing one using tape. However, the bonding area presents a higher risk of air leakage over extended use.

[0003] A related art air conditioning fresh air duct includes a first duct connected to the air conditioner's indoor unit at one end, a second duct that slots into the other end of the first duct, and a second duct that extends through a wall hole to connect to the outside. The first and second ducts are directly slotted together, eliminating the need for adhesive tape. This reduces the risk of air leakage at the connection over extended use.

[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] Pipe joints are prone to deformation, the risk of air leakage remains high, and the user experience is poor.

[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. The summary is not an extensive review, nor is it intended to identify key / critical elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0008] The embodiments of the present disclosure provide a component for connecting air ducts of an air conditioner and an air conditioner, so as to reduce the risk of deformation at the duct connection, thereby reducing the risk of air leakage at the duct connection and improving the user experience.

[0009] In some embodiments, an assembly for connecting air conditioning ducts includes: a rigid connecting tube, a first threaded tube, and a second threaded tube. The first threaded tube communicates with one end of the rigid connecting tube and is sleeved onto the inner or outer wall of the rigid connecting tube; the second threaded tube communicates with the other end of the rigid connecting tube and is sleeved onto the inner or outer wall of the rigid connecting tube; wherein the gap between the first threaded tube and the rigid connecting tube and the gap between the second threaded tube and the rigid connecting tube are blocked.

[0010] Optionally, a thread sealing layer is provided in the gap between the first threaded tube and the hard connecting tube and the gap between the second threaded tube and the hard connecting tube for sealing.

[0011] Optionally, a separation ring is provided in the middle of the thread sealing layer.

[0012] Optionally, both the connecting end of the first threaded tube and the connecting end of the second threaded tube are provided with anti-slip rings.

[0013] Optionally, when the inner side wall of the first threaded tube is sleeved with the outer side wall of the hard connecting tube, the anti-slip ring is provided on the outer side wall of the first threaded tube.

[0014] Optionally, the anti-slip ring is made of elastic material and is interference fit with the first threaded tube and the second threaded tube.

[0015] Optionally, an adapter is provided at one end of the first threaded tube facing away from the rigid connecting tube.

[0016] Optionally, the adapter includes a support ring and a connecting plate. The support ring is sleeved on the outside of the end of the first threaded tube and is provided with a clamping portion. The connecting plate is fixedly disposed on one side of the support ring and located inside the clamping portion, and is rotatably connected to the outer wall of the first threaded tube. When the assembly for connecting air conditioning ducts is assembled in an air conditioner for use, the clamping portion is clamped to the indoor unit of the air conditioner.

[0017] Optionally, the clamping portion is a clamping plate, which extends along the axis of the first threaded tube away from the support ring, and a clamping hole is provided on the clamping plate; wherein, when the component for connecting the air-conditioning duct is assembled in an air-conditioning and used, the clamping hole is clamped to the indoor unit of the air-conditioning.

[0018] In some embodiments, an air conditioner includes: a component for connecting an air duct of an air conditioner as described in the above embodiment.

[0019] The components for connecting air ducts of air conditioners and the air conditioner provided in the embodiments of the present disclosure can achieve the following technical effects:

[0020] Because the rigid connecting tube's ends are respectively connected to the first and second threaded tubes, the support and protection provided by the rigid connecting tubes, as well as the relatively high structural strength of the first and second threaded tubes themselves, reduces the risk of deformation at the pipe joints, thereby reducing the risk of air leakage and improving the user experience. Furthermore, the gaps between the first and second threaded tubes are sealed, providing excellent sealing performance and reducing the risk of airflow leaking out of the pipe.

[0038] 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.

[0039] 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.

[0040] Combine Figure 1 As shown, an embodiment of the present disclosure provides an assembly for connecting air ducts of an air conditioner, comprising: a rigid connecting tube 100, a first threaded tube 200, and a second threaded tube 300. The first threaded tube 200 is connected to one end of the rigid connecting tube 100 and is sleeved with the inner or outer wall of the rigid connecting tube 100; the second threaded tube 300 is connected to the other end of the rigid connecting tube 100 and is sleeved with the inner or outer wall of the rigid connecting tube 100; wherein the gap between the first threaded tube 200 and the rigid connecting tube 100 and the gap between the second threaded tube 300 and the rigid connecting tube 100 are blocked.

[0041] The assembly for connecting air conditioning ducts provided by the disclosed embodiment has a rigid connecting tube 100, with both ends of the rigid connecting tube 100 being respectively connected to the first threaded tube 200 and the second threaded tube 300. The rigid connecting tube 100 provides support and protection, as well as the relatively high structural strength of the first threaded tube 200 and the second threaded tube 300. This reduces the risk of deformation at the pipe connection, thereby reducing the risk of air leakage and improving the user experience. Furthermore, the gaps between the first threaded tube 200 and the rigid connecting tube 100, as well as the gaps between the second threaded tube 300 and the rigid connecting tube 100, are blocked, resulting in a good sealing performance and reducing the risk of airflow leaking out of the pipe.

[0042] Combine Figure 2 As shown, a thread sealing layer 400 is optionally provided to seal the gap between the first threaded tube 200 and the rigid connecting tube 100, as well as the gap between the second threaded tube 300 and the rigid connecting tube 100. This improves the sealing effect between the first threaded tube 200 and the rigid connecting tube 100, as well as the gap between the second threaded tube 300 and the rigid connecting tube 100, reducing the risk of air leakage. Furthermore, the thread sealing layer 400 can be threadedly connected to the first threaded tube 200 and the second threaded tube 300, providing a more stable connection. While ensuring a good seal, it also reduces the risk of the first threaded tube 200 and the second threaded tube 300 falling off.

[0043] For example, the gap between the first threaded tube 200 and the rigid connecting tube 100 and the gap between the second threaded tube 300 and the rigid connecting tube 100 can also be filled with a sealing material, such as sealing putty.

[0044] Specifically, when the first and second threaded tubes 200 and 300 are sleeved onto the inner sidewall of the rigid connecting tube 100, the threaded sealing layer 400 is disposed on the inner sidewall of the rigid connecting tube 100; and when the first and second threaded tubes 200 and 300 are sleeved onto the outer sidewall of the rigid connecting tube 100, the threaded sealing layer 400 is disposed on the outer sidewall of the rigid connecting tube 100. In this way, the threaded sealing layer 400 is compatible with the first and second threaded tubes 200 and 300, ensuring a secure connection and sealing effect between the first and second threaded tubes 200 and 300 and the threaded sealing layer 400.

[0045] Specifically, the inner and outer walls of the rigid connecting pipe 100 are both provided with thread sealing layers 400. In this way, the adaptability range of the rigid connecting pipe 100 is improved, and various connection requirements between the rigid connecting pipe 100 and the first threaded pipe 200 and the second threaded pipe 300 can be met.

[0046] Exemplarily, one of the first threaded tube 200 and the second threaded tube 300 is connected to the inner wall of the hard connecting tube 100 , and the other is connected to the outer wall of the hard connecting tube 100 .

[0047] Optionally, the diameter of one end of the rigid connecting tube 100 is larger than the diameter of the other end. This satisfies the assembly requirements of connecting one of the first threaded tube 200 and the second threaded tube 300 to the inner wall of the rigid connecting tube 100 and the other to the outer wall of the rigid connecting tube 100, and reduces the impact on the flow rate.

[0048] It can be understood that the inner side wall of the end of the hard connecting tube 100 with a larger diameter is used for connection, and the outer side wall of the end of the hard connecting tube 100 with a smaller diameter is used for connection.

[0049] Optionally, the thread sealing layer 400 is made of an elastic material. Thus, when the thread sealing layer 400 is threadedly connected to the first threaded pipe 200 and the second threaded pipe 300, the thread sealing layer 400 has elasticity and can better fill the gap between the first threaded pipe 200 and the rigid connecting pipe 100, as well as the gap between the second threaded pipe 300 and the rigid connecting pipe 100, thereby reducing the risk of air leakage.

[0050] Specifically, the thread sealing layer 400 is made of a rubber material. Thus, the thread sealing layer 400 made of a rubber material has good elasticity and anti-aging properties.

[0051] Combine Figure 3 As shown, a separator ring 410 is optionally provided in the middle of the threaded sealing layer 400. Thus, the separator ring 410 divides the threaded sealing layer 400 into two parts, one part connected to the first threaded pipe 200 and the other part connected to the second threaded pipe 300. The separator ring 410 provides separation and positioning in the middle of the threaded sealing layer 400, making the length of the connection more balanced.

[0052] Specifically, the thread sealing layer 400 and the separation ring 410 are integrally formed, so that the connection strength between the separation ring 410 and the thread sealing layer 400 is higher.

[0053] Optionally, both the connecting ends of the first and second threaded tubes 200 and 300 are provided with anti-slip rings 500. Because the materials of the first and second threaded tubes 200 and 300 are relatively soft and the pipe walls are relatively thin, the anti-slip rings 500 provided at the ends of the first and second threaded tubes 200 and 300 provide support for the ends of the first and second threaded tubes 200 and 300, reducing the risk of deformation. Furthermore, the connecting ends of the first and second threaded tubes 200 and 300 are less susceptible to deformation, facilitating the connection of the rigid connecting tube 100 to the first and second threaded tubes 200 and 300.

[0054] Optionally, when the inner sidewall of the first threaded tube 200 is sleeved with the outer sidewall of the rigid connecting tube 100, the anti-slip ring 500 is disposed on the outer sidewall of the first threaded tube 200. In this way, the anti-slip ring 500 provides an inward support force on the outer side of the first threaded tube 200, thereby reducing the risk of interference between the anti-slip ring 500 and the rigid connecting tube 100 during the connection process between the first threaded tube 200 and the rigid connecting tube 100.

[0055] Optionally, when the first and second threaded tubes 200 and 300 are sleeved with the inner sidewall of the rigid connecting tube 100, anti-slip rings 500 are provided on the inner sidewalls of the first and second threaded tubes 200 and 300. This reduces the risk of interference caused by the anti-slip rings 500 during the connection process between the first and second threaded tubes 200 and 300 and the rigid connecting tube 100.

[0056] Optionally, when the second threaded tube 300 is sleeved with the outer wall of the hard connecting tube 100, the outer wall of the second threaded tube 300 is provided with an anti-slip ring 500. In this way, the risk of interference caused by the anti-slip ring 500 during the connection process between the second threaded tube 300 and the hard connecting tube 100 is reduced.

[0057] Optionally, the anti-slip ring 500 is made of an elastic material and has an interference fit with the first and second threaded tubes 200 and 300. This provides elasticity to the anti-slip ring 500, allowing it to elastically deform during connection between the first and second threaded tubes 200 and 300 and the rigid connecting tube 100, making installation more convenient. Furthermore, the interference fit between the anti-slip ring 500 and the first and second threaded tubes 200 and 300 increases the strength of the connection between them and the rigid connecting tube 100.

[0058] Optionally, the first threaded tube 200 and the second threaded tube 300 are both made of polyethylene. Thus, the first threaded tube 200 and the second threaded tube 300 made of polyethylene have good aging resistance.

[0059] Optionally, the rigid connecting pipe 100 is made of polyvinyl chloride (PVC). Thus, the rigid connecting pipe 100 made of PVC has relatively high strength and relatively light weight.

[0060] Combine Figure 4 As shown, optionally, an adapter 600 is provided at one end of the first threaded tube 200 facing away from the hard connecting tube 100. 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 first threaded tube 200 and the indoor unit of the air conditioner.

[0061] Optionally, a side wall of the adapter 600 is flush with the end surface of the first threaded tube 200 facing away from the rigid connecting tube 100. Thus, when the adapter 600 is connected to the air conditioner indoor unit, the first threaded tube 200 does not protrude from the side wall of the adapter 600, reducing the risk of interference between the first threaded tube 200 and the air conditioner indoor unit.

[0062] Combine Figure 5 、 Figure 6 and Figure 7 As shown, the adapter 600 optionally includes a support ring 610 and a connecting plate 620. The support ring 610 is sleeved onto the outer end of the first threaded tube 200 and is provided with a clamping portion 630. The connecting plate 620 is fixed to one side of the support ring 610 and located inside the clamping portion 630. The connecting plate 620 is rotatably connected to the outer wall of the first threaded tube 200. When the air conditioner duct connection 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 first threaded tube 200 increases the connection and contact area, improves the connection stability, and reduces the risk of the connecting plate 620 detaching from the first threaded tube 200. Furthermore, the clamping portion 630 is clamped to the air conditioner's indoor unit, making installation and removal more convenient and efficient.

[0063] Optionally, one end of the connecting plate 620 is flush with the end surface of the first threaded tube 200 facing away from the rigid connecting tube 100, 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 first threaded tube 200 does not protrude from a side wall of the connecting plate 620, reducing the risk of interference between the first threaded tube 200 and the air conditioner indoor unit.

[0064] Optionally, the clamping portion 630 is a clamping plate 631 that extends along the axis of the first threaded tube 200 away from the support ring 610. The clamping plate 631 is provided with a clamping hole 632. When the air conditioner duct connection assembly is assembled and used in an air conditioner, the clamping hole 632 is engaged with the air conditioner's indoor unit. Thus, by engaging the air conditioner's indoor unit through the clamping hole 632, connection and removal are more convenient and more efficient.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] In some embodiments, an air conditioner includes: a component for connecting an air duct of an air conditioner as described in the above embodiment.

[0074] The air conditioner provided by the embodiment of the present disclosure includes the components for connecting the air conditioning duct according to the above-mentioned embodiment. Since the two ends of the rigid connecting pipe 100 are respectively connected to the first threaded pipe 200 and the second threaded pipe 300, the support and protection of the rigid connecting pipe 100, as well as the structural strength of the first threaded pipe 200 and the second threaded pipe 300 themselves, are relatively high. This reduces the risk of deformation at the pipe connection, thereby reducing the risk of air leakage and improving the user experience. In addition, the gaps between the first threaded pipe 200 and the rigid connecting pipe 100 and the gaps between the second threaded pipe 300 and the rigid connecting pipe 100 are blocked, resulting in good sealing performance and reducing the risk of airflow in the pipe leaking outward.

Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless expressly required, individual components and functions are optional, and the order of operations may vary.
