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 rotatable support rod. 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

[0047] 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 9 This utility model provides an indoor unit 100 for an air conditioner, including a bracket 10 and a support rod 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 rod 30 is disposed between the first air duct wall 111 and the second air duct wall 121. One end of the support rod 30 is rotatably mounted on the first air duct wall 111 via a pivot 40, and the other end of the support rod 30 is used to connect to the second air duct wall 121.

[0048] In this embodiment, the indoor unit 100 of the air conditioner includes a bracket 10 and a support rod 30. The bracket 10 has a first air duct wall 111 and a second air duct wall 121, and an air duct 20 is defined between the first air duct wall 111 and the second air duct wall 121. One end of the support rod 30 is rotatably connected to the first air duct wall 111, and the other end is connected to the second air duct wall 121. When installing the indoor unit 100, the support rod 30 is rotated towards the first air duct wall 111 to a position that does not affect the installation of the indoor unit 100, preventing the support rod 30 from interfering with the installation of the indoor unit 100, avoiding interference, and facilitating the installation and removal of the indoor unit 100. Furthermore, one end of the support rod 30 is rotatably connected to the first air duct wall 111, and the bracket 10 can rotate to a position parallel to the first air duct wall 111, preventing the support rod 30 from being broken or squeezed during transportation of the indoor unit 100 of the air conditioner, which would cause damage to the first air duct wall 111 and the second air duct wall 121.

[0049] In some embodiments of this utility model, such as Figure 2 , Figure 5 and Figure 6 As shown, one end of the support rod 30 connected to the second air duct wall 121 is connected to the second air duct wall 121 via a connecting structure 50. The connecting structure 50 includes a locking block 510, a groove 520, and a slot 530. The locking block 510 is disposed at the corresponding end of the support rod 30. The groove 520 is disposed on the second air duct wall 121, and the corresponding end of the support rod 30 is inserted into the groove 520. The groove 520 is arranged such that the corresponding end of the support rod 30 and the locking block 510 can be inserted. The slot 530 is disposed on the peripheral wall of the groove 520, and the locking block 510 is inserted into the slot 530.

[0050] In this embodiment, a locking block 510 is provided at one end of the support rod 30. A groove 520 and a slot 530 are provided on the second air duct wall 121, with the slot 530 located on the peripheral wall of the groove 520. When connecting the support rod 30 to the second air duct wall 121, the end of the support rod 30 with the locking block 510, along with the locking block 510, is inserted into the groove 520, so that the locking block 510 is inserted into the slot 530. When disassembling the support rod 30 from the second air duct wall 121, the end of the support rod 30 with the locking block 510, along with the locking block 510, is pulled out of the groove 520. The locking connection between the support rod 30 and the second air duct wall 121 facilitates the installation and disassembly of the support rod 30, thereby facilitating the installation and disassembly of the indoor unit 100 of the air conditioner.

[0051] In some embodiments of this utility model, such as Figure 3 As shown, the rotating shaft 40 is located on one side of the support rod 30, and the corresponding end of the support rod 30 contacts and abuts against the first air duct wall 111.

[0052] In this embodiment, the installation of the pivot 40 does not affect the contact and abutment between the support rod 30 and the first air duct wall 111. When the support rod 30 supports the first air duct wall 111 and the second air duct wall 121, the end of the support rod 30 with the pivot 40 contacts and abuts against the first air duct wall 111, preventing structural instability caused by gaps between the support rod 30 and the first air duct wall 111, thereby improving the structural stability of the indoor unit 100 of the air conditioner.

[0053] In some embodiments of this utility model, such as Figure 3 As shown, the locking block 510 and the rotating shaft 40 are respectively disposed on both sides of the support rod 30.

[0054] In this embodiment, the locking block 510 and the rotating shaft 40 are located on both sides of the support rod 30. When installing the indoor unit 100 of the air conditioner, the support rod 30 is rotated in the first direction so that the other end of the support rod 30 is close to the second air duct wall 121. During the rotation, the support rod 30 is directly inserted into the groove 520 of the second air duct wall 121. When disassembling the indoor unit 100 of the air conditioner, the other end of the support rod 30 is pulled out of the groove 520, and the support rod 30 is rotated in the opposite direction to the first direction so that the other end of the support rod 30 is away from the second air duct wall 121. The method of assembling and disassembling the support rod 30 is simple and convenient, facilitating the installation and disassembly of the indoor unit 100 of the air conditioner.

[0055] In some embodiments of this utility model, the locking block 510 and the rotating shaft 40 are disposed on the same side of the support rod 30.

[0056] In this embodiment, the locking block 510 and the rotating shaft 40 are located on the same side of the support rod 30. When installing the indoor unit 100 of the air conditioner, the support rod 30 is rotated in the first direction so that the other end of the support rod 30 is close to the second air duct wall 121. The support rod 30 bends so that the locking block 510 passes over the groove 520. The locking block 510 is inserted into the groove 520 in the opposite direction to the first direction to prevent the support rod 30 from turning backward after installation, thereby improving the stability of the connection between the support rod 30 and the second air duct wall 121, and thus improving the structural stability of the indoor unit 100 of the air conditioner.

[0057] In some embodiments of this utility model, such as Figure 2 Figure 6 and Figure 7 As shown, the end of the support rod 30 connected to the second air duct wall 121 has an insertion block 560, and a locking block 510 is disposed on the insertion block 560. The locking block 510 is provided with a locking groove 540, and the corresponding peripheral wall of the locking groove 530 is provided with a locking protrusion 550 for inserting into the locking groove 540.

[0058] In this embodiment, the support rod 30 has an insertion block 560, a locking block 510 is disposed on the insertion block 560, and a locking groove 540 is provided on the locking block 510. A locking protrusion 550 is provided on the peripheral wall of the locking groove 530. When the support rod 30 is connected to the second air duct wall 121, the insertion block 560 is inserted into the groove 520, the locking block 510 is inserted into the groove 530, and the locking protrusion 550 is inserted into the locking groove 540. By the cooperation of the insertion block 560 and the groove 520, and the locking protrusion 550 and the locking groove 540, the stability of the connection between the support rod 30 and the second air duct wall 121 is further improved, thereby improving the structural stability of the indoor unit 100 of the air conditioner.

[0059] In some other embodiments of this utility model, the card block 510 is provided with a card protrusion 550, and the corresponding peripheral wall of the card groove 530 is provided with a snap-fit ​​groove 540 for inserting the card protrusion 550.

[0060] In this embodiment, the protrusion 550 is disposed on the block 510, and the latching groove 540 is disposed on the peripheral wall of the groove 530. The protrusion 550 and the latching groove 540 are engaged to improve the stability of the connection between the support rod 30 and the second air duct wall 121, thereby improving the stability of the structure of the indoor unit 100 of the air conditioner.

[0061] In some embodiments of this utility model, such as Figure 3 As shown, the air outlet 620 of the air duct 20 extends along a straight line, and the rotating shaft 40 is perpendicular to the straight line.

[0062] In this embodiment, the extension direction of the rotating shaft 40 is perpendicular to the air outlet 620 of the air duct 20. When the indoor unit 100 of the air conditioner discharges air, the airflow passes through the support rod 30, and the flow of air has a certain pushing effect on the support rod 30. The rotating shaft 40 is perpendicular to the direction of the airflow, which avoids the support rod 30 from swaying due to the air discharge of the indoor unit 100 of the air conditioner, improves the stability of the support rod 30 structure, and thus improves the stability of the indoor unit 100 structure.

[0063] In some embodiments of this utility model, a torsion spring is provided at the rotating shaft 40, and the torsion spring is configured to cause the other end of the support rod 30 to approach the first air duct wall 111.

[0064] In this embodiment, a torsion spring is provided at the pivot 40, which causes the other end of the support rod 30 to approach the first air duct wall 111. When the other end of the support rod 30 is not connected to the second air duct wall 121, the other end of the support rod 30 is always close to the first air duct wall 111, that is, the side of the support rod 30 is in contact with the first air duct wall 111, to prevent affecting the installation or removal of the indoor unit 100 of the air conditioner, avoid interference, and facilitate the installation and removal of the indoor unit 100 of the air conditioner.

[0065] In some embodiments of this utility model, such as Figure 3and Figure 4 As shown, the support rod 30 has a first rotational position and a second rotational position. When the support rod 30 is in the first rotational position, the other end of the support rod 30 is connected to the second air duct wall 121. When the support rod 30 is in the second rotational position, the other end of the support rod 30 is close to the first air duct wall 111, and the support rod 30 is detachably mounted on the first air duct wall 111 by a snap-fit ​​mechanism.

[0066] In this embodiment, when the support rod 30 is in the first rotation position, both ends of the support rod 30 are connected to the first air duct wall 111 and the second air duct wall 121, respectively. The support rod 30 supports the first air duct wall 111 and the second air duct wall 121 to prevent them from bending and deforming. When the support rod 30 is in the second rotation position, both ends of the support rod 30 are in contact with the first air duct wall 111 to prevent interference with the installation and disassembly of the indoor unit 100 of the air conditioner.

[0067] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the support frame 10 includes a supporting frame 120 and a splicing frame 110. The supporting frame 120 has an upward-facing second air duct wall 121. The splicing frame 110 is located on the upper side of the front end of the support body, and has a downward-facing first air duct wall 111. The support rod 30 is located at the front of the air duct 20.

[0068] In this embodiment, the bracket 10 includes a supporting frame 120 and a splicing frame 110. The splicing frame 110 includes a first air duct wall 111, which is disposed downwards. The supporting frame 120 includes a second air duct wall 121, with the first air duct wall 111 positioned above the second air duct wall 121. The support rod 30 is located at the front of the air duct 20. When assembling the indoor unit 100 of the air conditioner, the splicing frame 110 is inserted above the second air duct wall 121 of the bracket 10, so that the first air duct wall 111 and the second air duct wall 121 are positioned opposite each other. Then, the supporting assembly is connected to the second air duct wall 121. When repairing the indoor unit 100 of the air conditioner, the splicing frame 110 can be disassembled first, allowing the components connected to the splicing frame 110 to be removed from the indoor unit 100 for repair. Moreover, after the splicing frame 110 is disassembled, the indoor unit 100 of the air conditioner has a larger operating space, facilitating the repair of components inside the indoor unit 100 that are difficult to disassemble.

[0069] In some embodiments of this utility model, such as Figure 1 , Figure 8 and Figure 9As shown, the indoor unit 100 of the air conditioner also includes a front panel 610, a heat exchanger 640, and a cross-flow fan 650. The front panel 610 has an air outlet 620 and is located on the front side of the splicing frame 110 and the support frame 120. The air outlet 620 corresponds to the air duct 20. The front panel 610 also has an air inlet 630, which is located above the air outlet 620. The heat exchanger 640 is located on the upper side of the support frame 120, and its lower front end is located within a water collection tray 660 on the splicing frame 110. The cross-flow fan 650 is rotatably mounted on the support frame 120.

[0070] In this embodiment, the splicing frame 110 also includes a water receiving tank 660, which is located above the first air duct wall 111, with the first air duct wall 111 facing downwards and the opening of the water receiving tank 660 facing upwards. A heat exchanger 640 is located on the upper side of the supporting frame 120, with its lower front end inside the water receiving tank 660. A cross-flow fan 650 is located at the front of the air duct 20 and is mounted on the supporting frame 120. A front panel 610 is located in front of the supporting frame 120 and the splicing frame 110, and has an air inlet 630 and an air outlet 620, with the air inlet 630 located above the air outlet 620. When the air conditioner is running, airflow enters the indoor unit 100 of the air conditioner through the air inlet 630, undergoes heat exchange through the heat exchanger 640 to form a heat exchange airflow, and is blown into the room from the air outlet 620 under the action of the cross-flow fan 650. The condensate formed on the heat exchanger 640 is prevented from flowing into the water receiving tank 660 along the heat exchanger 640.
