Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an indoor unit of an air conditioner with a retractable support assembly. Background Technology

[0002] When an air conditioner's indoor unit blows air into the room, the airflow passes through an air duct. This duct is defined by opposing first and second duct walls. In a recessed air conditioner indoor unit, the first duct wall is above, and the second duct wall is below, both extending horizontally. The first and second duct walls only have connecting structures at their ends. Due to their relatively long lateral lengths, both walls are prone to deformation, especially the upper first duct wall. To address this, some air conditioners incorporate a support assembly between the first and second duct walls. One end of the support assembly connects to the first duct wall, and the other end connects to the second duct wall. However, since the support assembly is a straight rod, its elasticity is required to bend and fit between the first and second duct walls during assembly. This can cause interference, making installation and disassembly of the air conditioner indoor unit difficult. Utility Model Content

[0051] Figure 1 This is a schematic structural diagram of a splicing skeleton according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 8 This utility model provides an indoor unit 100 for an air conditioner, including a bracket 10 and a support assembly 30. The bracket 10 has a first air duct wall 111 and a second air duct wall 121 disposed opposite to each other to define an air duct 20. The support assembly 30 is disposed between the first air duct wall 111 and the second air duct wall 121. The support assembly 30 has a first rod 310 and a second rod 330. One end of the first rod 310 is used to connect to the first air duct wall 111, and one end of the second rod 330 is used to connect to the second air duct wall 121. The second rod 330 is telescopically mounted on the first rod 310.

[0052] In this embodiment, the indoor unit of the air conditioner includes a bracket 10 and a support assembly 30. The bracket 10 includes a first air duct wall 111 and a second air duct wall 121, defining an air duct 20 between the first air duct wall 111 and the second air duct wall 121. The support assembly 30 includes a first rod 310 and a second rod 330. The first rod 310 is connected to the first air duct wall 111, and the second rod 330 is connected to the second air duct wall 121. The other end of the second rod 330 is retractably mounted on the first rod 310. When installing the indoor unit 100, the second rod 330 is first retracted, and after other components are installed, the second rod 330 is extended and mounted on the second air duct wall 121. Due to the retractable nature of the second rod 330, the installation or removal of the indoor unit 100 is prevented from interfering with the installation or removal of the indoor unit 100, avoiding interference and facilitating the installation and removal of the indoor unit 100. Furthermore, only the first rod 310 on the support assembly 30 is connected to the first air duct wall 111, to prevent the support assembly 30 from being damaged or the first air duct wall 111 and the second air duct wall 121 from being damaged due to compression between the support assembly 30 and the indoor unit 100 of the air conditioner during transportation.

[0053] In some embodiments of this utility model, such as Figure 2 As shown, a groove 320 is provided on the first rod 310, and the second rod 330 is telescopically disposed within the groove 320. A limiting structure 40 is provided on the groove 320, and a first locking protrusion 340 that cooperates with the limiting structure 40 is provided on the second rod 330. The first locking protrusion 340 and the limiting structure 40 are arranged to prevent the second rod 330 from retracting into the first rod 310.

[0054] In this embodiment, the first rod 310 is provided with a sliding groove 320, and a limiting structure 40 is provided on the sliding groove 320. The second rod 330 is provided with a first locking protrusion 340. The second rod is slidably disposed in the sliding groove 320, and the first locking protrusion 340 engages with the limiting structure 40 to prevent the second rod 330 from retracting into the sliding groove 320. When connecting the second rod 330 to the second air duct wall 121, the second rod 330 extends out of the sliding groove 320. After the second rod 330 extends a certain length, the first locking protrusion 340 engages with the limiting structure 40, and then the second rod 330 is connected to the second air duct wall 121. By cooperating with the first protrusion 340 and the limiting structure 40, when the support component 30 supports the first air duct wall 111 and the second air duct wall 121, the first support and the second rod 330 are prevented from sliding relative to each other, thereby improving the structural stability of the support component 30 and preventing the first air duct wall 111 or the second air duct wall 121 from bending, thus improving the structural stability of the air conditioner indoor unit 100.

[0055] In some embodiments of this utility model, such as Figure 3 As shown, the second rod 330 is provided with a second latching protrusion 350 that cooperates with the limiting structure 40. The second latching protrusion 350 and the limiting structure 40 are arranged to prevent the second rod 330 from extending outward to the first rod 310. The first latching protrusion 340 is positioned near the first air duct wall 111 relative to the second latching protrusion 350, such that when the first latching protrusion 340 cooperates with the limiting structure 40, the length of the support component 30 is greater than the length of the support component 30 when the second latching protrusion 350 cooperates with the limiting structure 40.

[0056] In this embodiment, a second latching protrusion 350 is also provided on the second rod 330, which is located on the side of the first latching protrusion 340 away from the first air duct wall 111. When installing the indoor unit 100 of the air conditioner, the second rod 330 slides along the slide groove 320 away from the first air duct wall 111. When the second rod 330 slides to the connection position where it contacts the second air duct wall 121, under the pressure of the first air duct wall 111 and the second air duct wall 121, the second air duct wall 121 has a force that causes the second rod 330 to retract. The first latching protrusion 340 cooperates with the limiting structure 40 to prevent the second rod 330 from retracting into the slide groove 320. When disassembling the indoor unit 100 of the air conditioner, after the second rod 330 is removed from the second air duct wall 121, it is pushed towards the first air duct wall 111 to retract it into the slide groove 320. After the second rod 330 retracts, the second latching protrusion 350 engages with the limiting structure 40 to prevent the second rod 330 from extending outward. By engaging the second latching protrusion 350 with the limiting structure 40, the second rod 330 is limited after retracting into the slide groove 320, preventing the second rod 330 from extending and obstructing the installation or disassembly of other structures, thereby facilitating the installation and disassembly of the indoor unit 100 of the air conditioner.

[0057] In some embodiments of this utility model, such as Figure 2 As shown, the limiting structure 40 is a limiting plate 410, which is disposed at one end of the slide groove 320 and defines a telescopic opening for the extension and retraction of the second rod 330. The edge of the limiting plate 410 away from the telescopic opening contacts and engages with the second latching protrusion 350. The limiting plate 410 is provided with a limiting hole 420 for the insertion of the first latching protrusion 340.

[0058] In this embodiment, the limiting structure 40 is a limiting plate 410, which is disposed on the slide groove 320 and defines a telescopic opening with the slide groove 320. A limiting hole 420 is provided on the limiting plate 410. The second rod 330 enters the slide groove 320 through the telescopic opening. When the second rod 330 extends out of the slide groove 320, the first locking protrusion 340 inserts into the limiting hole 420 and contacts the edge of the limiting hole 420 away from the telescopic opening, preventing the second rod 330 from retracting. When the second rod 330 retracts into the slide groove 320, the second locking protrusion 350 contacts the edge of the limiting plate 410 away from the telescopic opening, preventing the second rod 330 from extending further. Through the cooperation of the first locking protrusion 340 with the limiting hole 420 and the second locking protrusion 350 with the limiting plate 410, the second rod 330 is positioned. The limiting structure 40 has a simple structure, is easy to process and manufacture, and is easy for users to operate, thus facilitating the installation and disassembly of the indoor unit 100 of the air conditioner.

[0059] In some embodiments of this utility model, such as Figure 4 As shown, the second rod 330 includes an insertion portion 331 and a pressing plate 333. The insertion portion 331 has a through hole 332 extending along the sliding direction of the second rod 330. The insertion portion 331 is slidably disposed within the slide groove 320. The pressing plate 333 is disposed at the through hole 332 and extends along the sliding direction of the second rod 330. Both ends of the pressing plate 333 are connected to the insertion portion 331. The two edges of the pressing plate 333 extending along the sliding direction of the second rod 330 are respectively spaced apart from the two edges of the corresponding through hole 332 extending along the sliding direction of the second rod 330. The pressing plate 333 is spaced apart from the bottom wall of the slide groove 320 to provide a pressing space. The first locking protrusion 340 and the second locking protrusion 350 are both disposed on the surface of the pressing plate 333 facing the limiting plate 410.

[0060] In this embodiment, the second rod 330 includes an insertion portion 331, which has a through hole 332 extending along the sliding direction of the second rod 330. A pressing plate 333 is disposed at the through hole 332, and two edges of the pressing plate 333 extending along the sliding direction of the second rod 330 are respectively spaced apart from the edges of the through hole 332. A first locking protrusion 340 and a second locking protrusion 350 are disposed on the side of the pressing plate 333 facing the limiting plate 410, and a pressing space is formed between the other side of the pressing plate 333 and the bottom wall of the slide groove 320. When the second rod 330 extends outward, press the pressing plate 333 towards the bottom wall of the slide groove 320, causing the pressing plate 333 to bend towards the bottom wall of the slide groove 320. Pull the second rod 330 away from the first air duct wall 111, and the second locking protrusion 350 no longer contacts and abuts against the limiting plate 410. The second locking protrusion 350 passes through the space between the limiting plate 410 and the slide groove 320, pushing the second rod 330 to the position where the first locking protrusion 340 engages with the limiting plate 410. When the second rod 330 retracts into the slide groove 320, press the pressing plate 333 towards the bottom wall of the slide groove 320, causing the pressing plate 333 to bend towards the bottom wall of the slide groove 320. Pull the second rod 330 towards the first air duct wall 111, and the first locking protrusion 340 disengages from the limiting hole 420, pushing the second rod 330 to the position where the second locking protrusion 350 engages with the limiting plate 410. The insertion part 331 and the pressing part facilitate the first locking protrusion 340 and the second locking protrusion 350 to disengage from the limiting device, preventing damage to the second rod 330 or the first rod 310 caused by forced disengagement, and facilitating the installation and disassembly of the indoor unit 100 of the air conditioner.

[0061] In some embodiments of this utility model, such as Figure 4 As shown, both the first locking protrusion 340 and the second locking protrusion 350 are wedge-shaped blocks. The stop surface of the first locking protrusion 340 that contacts and engages with the limiting plate 410 is perpendicular to the limiting plate 410. The stop surface of the second locking protrusion 350 that contacts and engages with the limiting plate 410 is perpendicular to the limiting plate 410.

[0062] In this embodiment, both the first latching protrusion 340 and the second latching protrusion 350 are wedge-shaped. The stop surface of the first latching protrusion 340 that contacts and engages with the limiting plate 410 is perpendicular to the limiting plate 410, and the stop surface of the second latching protrusion 350 that contacts and engages with the limiting plate 410 is also perpendicular to the limiting plate 410. That is, the cross-sectional area of ​​the ends of the first latching protrusion 340 and the second latching protrusion 350 closer to the second rod 330 is larger, and the cross-sectional area of ​​the ends of the first latching protrusion 340 and the second latching protrusion 350 farther from the second rod 330 is smaller. The other side of the first latching protrusion 340 opposite to the limiting plate 410 slopes away from the stop surface from the end of the latching protrusion to the root of the latching protrusion, and the other side of the second latching protrusion 350 opposite to the limiting plate 410 slopes away from the stop surface from the end of the latching protrusion to the root of the latching protrusion. When the second rod 330 is pushed into the slide groove 320, it requires less effort to push because the opposite side of the second latching protrusion 350, which is opposite to the limiting plate 410, is inclined. Similarly, when the second rod 330 slides out of the slide groove 320, it requires less effort to push because the opposite side of the first latching protrusion 340, which is opposite to the limiting plate 410, further facilitating the extension and retraction of the second rod 330, thereby facilitating the installation and removal of the indoor unit 100 of the air conditioner.

[0063] In some embodiments of this utility model, such as Figure 3 As shown, the first rod 310 is integrally formed with the first air duct wall 111. The end of the second rod 330 connected to the second air duct wall 121 is connected to the second air duct wall 121 through the connecting structure 50.

[0064] In this embodiment, the first rod 310 is integrally formed with the first air duct wall 111, and the second rod 330 is connected to the second air duct wall 121 via the connecting structure 50. The integral forming of the first rod 310 enhances the structural strength between the first rod 310 and the first air duct wall 111. Moreover, only one end of the first rod 310 of the support assembly 30 is connected to the first air duct wall 111, so the support assembly 30 will not be damaged during transportation due to supporting the first air duct wall 111 and the second air duct wall 121. When installing or removing the indoor unit 100 of the air conditioner, it is only necessary to extend or retract the second rod 330 to connect or disconnect the second rod 330 from the second air duct wall 121, further simplifying the installation process of the support assembly 30 and thus facilitating the installation and removal of the indoor unit 100 of the air conditioner.

[0065] In some embodiments of this utility model, such as Figure 2 , Figure 5 and Figure 6As shown, the connecting structure 50 includes a locking block 510, a groove 520, and a slot 530. The locking block 510 is disposed at a corresponding end of the second rod 330. The groove 520 is disposed on the second air duct wall 121. A corresponding end of the support assembly 30 is inserted into the groove 520.

When disassembling the second rod 330, the end of the second rod 330 with the locking block 510, along with the locking block 510, is pulled out of the groove 520. The second rod 330 is engaged with the second air duct wall 121, facilitating the installation and disassembly of the second rod 330, and consequently, facilitating the installation and disassembly of the indoor unit 100 of the air conditioner.

By the cooperation of the insertion block 560 and the groove 520, and the engagement of the third locking protrusion 550 and the locking groove 540, the stability of the connection between the second rod 330 and the second air duct wall 121 is further improved, thereby improving the structural stability of the indoor unit 100 of the air conditioner.

[0069] In some other embodiments of this utility model, the card block 510 is provided with a third card protrusion 550, and the corresponding peripheral wall of the card groove 530 is provided with a snap-fit ​​groove 540 for inserting the third card protrusion 550.
