The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0048] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0049] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0050] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0051] Reference Figure 1 and Figure 2 As shown, an integrated air conditioner of an embodiment of the present invention is an integrated air conditioner of a double air duct structure, including an air inlet and exhaust assembly 20 and an outdoor heat exchange assembly 30, and the two ends of the air inlet and exhaust assembly 20 are respectively connected to the window and the outdoor heat exchange assembly 30. Specifically, the air inlet and exhaust assembly 20 includes two air ducts arranged in a tube-in-tube structure, and a joint assembly 10 that simultaneously connects the two air ducts, and the joint assembly 10 is connected to the window through a sealing plate 40; the outdoor heat exchange assembly 30 includes a condenser 31 and an exhaust volute 32, one of the air ducts of the air inlet and exhaust assembly 20 guides outdoor air to enter from the air inlet of the integrated air conditioner through the joint assembly 10, and after the air passes through the condenser 31 for heat exchange, the exhaust volute 32 discharges the heat-exchanged air to the other air duct of the air inlet and exhaust assembly 20, and then discharges it to the outdoors through the joint assembly 10, thereby realizing the heat exchange process of the integrated air conditioner.

[0052] Reference Figure 2 and Figure 3 As shown, a joint assembly 10 according to an embodiment of the present invention comprises a hollow outer tube connector 100 and a hollow outer tube rotating body 200. One end of the outer tube connector 100 is provided with a first air duct connector 110. The first air duct connector 110 can be used to connect the first air duct 50. Figure 2 The first air duct 50 shown is an outer tube. The outer tube rotating body 200 is rotatably connected to the other end of the outer tube connecting body 100, so that the outer tube rotating body 200 can rotate relative to the first air duct 50. After the sealing plate 40 is installed on the outer tube rotating body 200, the user can easily install the sealing plate 40 horizontally or vertically when installing the sealing plate 40 on the window, which is more convenient to operate and improves the user experience. In addition, the first air duct 50 will not be affected by the torsional force, which reduces the risk of separation of the two ends of the first air duct 50. In addition, the joint assembly 10 of this embodiment also includes a hollow inner tube rotating body 300 and a hollow inner tube connecting body 400. The inner tube connecting body 400 is rotatably connected to the inner tube rotating body 300. The end of the inner tube connecting body 400 away from the inner tube rotating body 300 is provided with a second air duct connecting portion 410. The second air duct connecting portion 410 can be used to connect the second air duct 60, such as Figure 2The second air duct 60 is an inner tube that is sleeved inside an outer tube. The inner tube rotating body 300 is fixedly connected to the outer tube rotating body 200, so that when the outer tube rotating body 200 is rotated and adjusted, the second air duct 60 will not rotate along with it, so the second air duct 60 will not be affected by the torsional force, reducing the risk of the two ends of the second air duct 60 being separated and improving the reliability of the connection of the second air duct 60.

[0053] Reference Figure 2 , Figure 3 and Figure 4 As shown, it should be noted that a first air duct 210 is formed in the outer tube rotating body 200 and the outer tube connecting body 100, and the first air duct 210 extends to the integrated air conditioner through the first air duct 50, and a second air duct 310 is formed in the inner tube connecting body 400 and the inner tube rotating body 300, and the second air duct 310 extends to the integrated air conditioner through the second air duct 60; it can be understood that one of the first air duct 210 and the second air duct 310 can be set as an air inlet duct, and the other can be set as an exhaust duct. Therefore, through the joint assembly 10, and the tube-in-tube structure arranged inside and outside the second air duct 60 and the first air duct 50, the first air duct 210 and the second air duct 310 are separated from each other and form an air inlet duct and an exhaust duct respectively, avoiding cross-winding between the air inlet duct and the exhaust duct, and also avoiding heat exchange between the first air duct 210 and the second air duct 310, thereby affecting the heat exchange efficiency of the integrated air conditioner, and the installation structure is simpler and the assembly is more convenient.

[0054] Reference Figure 5 As shown, in some embodiments of the present invention, a first outer tube connection part 120 is formed at one end of the outer tube connector 100 away from the first air duct connection part 110, and a second outer tube connection part 220 is formed at one end of the outer tube rotating body 200, and the first outer tube connection part 120 and the second outer tube connection part 220 are rotatably matched to each other so that the outer tube rotating body 200 and the outer tube connector 100 can achieve stable rotation. It should be noted that the matching structure of the first outer tube connection part 120 and the second outer tube connection part 220 can be a quick connector, a gear transmission or a plane bearing, etc., which can realize the rotation between two upper and lower components in the axial direction, and it is not specifically limited here. It can be understood that a sealing connection is adopted between the first outer tube connection part 120 and the second outer tube connection part 220, such as Figure 2 As shown, when the space between the first air duct 50 and the second air duct 60 is defined as an air inlet duct, the sealing of the air inlet duct can be ensured and the air intake efficiency can be improved.

[0055] Reference Figure 5 and Figure 6As shown, in some embodiments of the present invention, the first outer tube connection part 120 is an annular convex rib. It can be understood that the annular convex rib can be formed by multiple segments of arc convex ribs arranged at intervals along the circumferential direction, or can be a segment of annular convex rib; the second outer tube connection part 220 is an annular groove, and the annular convex rib and the annular groove are rotatably matched, so as to realize the stable rotation of the outer tube rotating body 200 relative to the outer tube connection body 100. It should be noted that there can be many structural forms for realizing the cooperation between the annular convex rib and the annular groove, such as realizing the connection on the outside of the first air duct 210, or realizing the connection on the inside of the first air duct 210, etc. The changes, deformations or equivalent structures made by those skilled in the art based on the above embodiments are all within the protection scope of the present invention.

[0056] Further, see Figure 6 and Figure 7 As shown, the lower end of the outer tube rotating body 200 is provided with a shroud 230 extending downward, and the annular convex rib is provided on the inner side of the shroud 230, and the upper end of the outer tube connecting body 100 is provided with a convex ring 130 extending upward, and the annular groove is provided on the outer side of the convex ring 130, and there is a matching gap between the annular convex rib and the annular groove to realize the mutual rotation along the axis of the joint assembly 10, and the sealing effect is good, which can effectively prevent the first air duct 210 from leaking air from the matching point between the two. Further, the lower end of the outer tube rotating body 200 is also provided with a bottom edge 240, and the bottom edge 240 is connected to the shroud 230 and extends inward along the vertical direction of the shroud 230, so that the bottom edge 240, the shroud 230 and the annular convex rib form a structure with a U-shaped cross section, and the structure formed by the annular groove and the upper end of the convex ring 130 is surrounded and sealed, further improving the stability of the connection between the outer tube rotating body 200 and the outer tube connecting body 100, effectively preventing the two from loosening; and further improving the sealing performance of the matching point.

[0057] In some embodiments of the present invention, the second outer tube connection part 220 is an annular convex rib, and the first outer tube connection part 120 is an annular groove that rotatably cooperates with the annular convex rib, so that the outer tube rotating body 200 can stably rotate relative to the outer tube connection body 100, and the sealing performance is good. The technical principle and technical effect of this embodiment can be appropriately referred to the above embodiment, and will not be described in detail here to avoid repetition.

[0058] Reference Figure 3 As shown, in some embodiments of the present invention, the inner tube rotating body 300 extends outwardly in the axial direction (ie Figure 3 A certain distance upwards, such as 20mm, 30mm, etc. Figure 5As shown, the distance between the upper end surface of the inner tube rotating body 300 and the upper end surface of the outer tube rotating body 200 is L, and L satisfies: L≥20mm, so that the end of the exhaust air duct facing the outdoors and the end of the air inlet air duct facing the outdoors are staggered by a certain distance, so as to prevent the air discharged from the exhaust air duct after heat exchange from being sucked into the outdoor heat exchange component 30 by the air inlet air duct, thereby forming a cross-wind phenomenon, resulting in a decrease in the energy efficiency of the integrated air conditioner. For example, if the integrated air conditioner is in cooling mode, and the first air duct 50 is used for air intake and the second air duct 60 is used for exhaust, the outer tube rotating body 200 discharges hot air to the outdoors. By designing the inner tube rotating body 300 to extend outward relative to the upper end surface of the outer tube rotating body 200, it can be prevented that the hot air is directly sucked back into the condenser 31 by the outer tube rotating body 200, thereby improving the heat exchange efficiency of the integrated air conditioner.

[0059] Reference Figure 5 As shown, in some embodiments of the present invention, a first inner tube connection portion 320 is formed on the lower end surface of the inner tube rotating body 300, and a second inner tube connection portion 420 is formed at one end of the inner tube connecting body 400. The first inner tube connection portion 320 and the second inner tube connection portion 420 are rotatably matched to enable the inner tube connecting body 400 and the inner tube rotating body 300 to rotate stably, thereby avoiding the first air duct 50 from being subjected to torsional force when the sealing plate 40 is installed, and reducing the risk of separation of the two ends of the first air duct 50. It should be noted that the matching structure of the first inner tube connection portion 320 and the second inner tube connection portion 420 can be a quick connector, a gear transmission, or a plane bearing, etc., which can realize the rotation between two upper and lower components in the axial direction, and is no longer specifically limited here. It can be understood that a sealing connection is adopted between the first inner tube connection portion 320 and the second inner tube connection portion 420, such as Figure 2 As shown, when the second air duct 60 is defined as an exhaust air duct, the sealing of the exhaust air duct can be ensured and the exhaust efficiency can be improved.

[0060] Reference Figure 7As shown, in some embodiments of the present invention, specifically, the first inner tube connection part 320 is formed as an annular groove, and the second inner tube connection part 420 is an annular convex rib. It can be understood that the annular convex rib can be formed by multiple arc convex ribs arranged at intervals along the circumferential direction, or it can be a section of annular convex rib; the annular convex rib rotates with the annular groove, so as to realize the stable rotation of the inner tube rotating body 300 relative to the inner tube connecting body 400. It should be noted that there can be many structural forms for realizing the cooperation between the annular convex rib and the annular groove, such as realizing the connection on the outside of the second air duct 310, or realizing the connection on the inside of the second air duct 310, etc. The changes, deformations or equivalent structures made by those skilled in the art according to the above embodiments belong to the protection scope of the present invention. As another embodiment, the second inner tube connection part 420 is an annular convex rib, and the first inner tube connection part 320 is an annular groove that rotates with the annular convex rib, so as to realize the stable rotation of the inner tube rotating body 300 relative to the inner tube connecting body 400, and the sealing performance is good.

[0061] Reference Figure 7 As shown, in some embodiments of the present invention, the outer tube rotating body 200 includes a first outer tube connecting plate 250 and a second outer tube connecting plate 260 that are relatively arranged. The first outer tube connecting plate 250 and the second outer tube connecting plate 260 can be processed and formed separately, such as by injection molding, and fixedly connected to form the outer tube rotating body 200, which has high structural stability and low production cost, and reduces the manufacturing difficulty of the outer tube rotating body 200 and the outer tube connecting body 100, thereby improving the assembly efficiency.

[0062] Furthermore, the inner tube rotating body 300 includes a first inner tube connecting plate 330 and a second inner tube connecting plate 340 that are relatively arranged. The first inner tube connecting plate 330 and the second inner tube connecting plate 340 can be processed and formed separately, such as by injection molding, and fixedly connected to form the inner tube rotating body 300. It has high structural stability and low production cost, and it reduces the manufacturing difficulty of the inner tube rotating body 300 and the inner tube connector 400, thereby improving the assembly efficiency.

[0063] Furthermore, the first outer tube connecting plate 250 is fixedly connected to the first inner tube connecting plate 330 to form a first joint connector 500, and the second outer tube connecting plate 260 is fixedly connected to the second inner tube connecting plate 340 to form a second joint connector 600 that cooperates with the first joint connector 500. Therefore, the first joint connector 500 and the second joint connector 600 that are relatively arranged can be injection molded separately and then assembled, thereby improving the structural stability of the outer tube rotating body 200 and the inner tube rotating body 300, facilitating the installation of the outer tube connector 100 and the inner tube connector 400, reducing the manufacturing difficulty and production cost of the joint assembly 10, and improving the assembly efficiency.

[0064] Specifically, in some embodiments of the present invention, the first outer tube connection plate 250 is provided with a first connection ear 251, and the second outer tube connection plate 260 is provided with a second connection ear 261. The first connection ear 251 and the second connection ear 261 are respectively provided in two groups along the left and right directions. The two groups of first connection ears 251 and second connection ears 261 are connected by fasteners, so that the first joint connector 500 and the second joint connector 600 are stably connected, ensuring the stability of the connection between the outer tube rotating body 200 and the outer tube connecting body 100, and also ensuring the stability of the connection between the inner tube connecting body 400 and the inner tube rotating body 300. It can be understood that the fastener can be a screw, a bolt, a rivet or a pin, etc., which is not specifically limited here.
