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 scissor-type 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

[0045] Figure 1 This is a schematic structural diagram of a scissor-type support assembly in a combined state according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 7 This utility model provides an indoor unit 100 for an air conditioner, including a bracket 10 and a scissor support assembly 30. The bracket 10 has two opposing air duct walls to define an air duct 20. The scissor support assembly 30 is disposed between the two air duct 20 walls and has two support rods 310. The two support rods 310 are rotatably connected to form a scissor structure. One end of each support rod 310 is used to contact one air duct 20 wall, and the other end is used to connect to the other air duct 20 wall. After the support rod 310 is connected to the corresponding air duct 20 wall, it prevents the two support rods 310 from opening.

[0046] In this embodiment, the indoor unit 100 of the air conditioner includes a bracket 10 and a scissor support assembly 30. The bracket 10 includes two opposing air duct 20 walls, defining an air duct 20 between the two air duct 20 walls. The scissor support assembly 30 includes two support rods 310, with each end of the support rod 310 connected to the two air duct 20 walls respectively. The two support rods 310 are rotatably connected to form a scissor structure. When installing the indoor unit 100, after installing other components of the indoor unit 100, the two support rods 310 are joined together, with each end of the support rod 310 abutting against the two air duct 20 walls, and the air duct 20 walls preventing the support rods 310 from opening. When disassembling the indoor unit 100, the two support rods 310 are opened, and the ends of the support rods 310 detach from the air duct 20 walls, allowing the support structure to be removed. The scissor-type support assembly 30 facilitates installation and disassembly, preventing it from interfering with the installation and disassembly of the air conditioner, thus simplifying the installation and disassembly of the indoor unit 100. Furthermore, the scissor-type support assembly 30 is a separate structure, preventing damage to the first air duct wall 111 and the second air duct wall 121 during transportation, thus facilitating the transport of the indoor unit 100.

[0047] In some embodiments of this utility model, such as Figure 2 As shown, each support rod 310 is connected to the corresponding duct 20 wall via a connecting structure 50. Each connecting structure 50 includes a locking block 510, a groove 520, and a slot 530. The locking block 510 is disposed at one end of the corresponding support rod 310 and is located on one side of the support rod 310. The groove 520 is disposed on the corresponding duct 20 wall, and the corresponding end of the support rod 310 is inserted into the groove 520. The groove 520 is arranged such that the corresponding end of the scissor support assembly 30 and the locking block 510 can be inserted. The slot 530 communicates with the groove 520, and the locking block 510 is inserted into the slot 530 during the merging of the two support rods 310. The locking block 510 is provided with a latching groove 540, and the corresponding peripheral wall of the slot 530 is provided with a latching protrusion 550 for inserting into the latching groove 540.

[0048] In this embodiment, a locking block 510 is provided at one end of the support rod 310, and a locking groove 540 is provided on the locking block. A groove 520 and a locking slot 530 are provided on the corresponding air duct 20 wall, and the groove 520 and the locking slot 530 are connected. A locking protrusion 550 is provided on the peripheral wall of the locking slot 530. When connecting the support rod 310 and the air duct 20 wall, the locking block 510 on the support rod 310 is inserted into the groove 520, so that the locking block 510 is inserted into the locking slot 530. At the same time, the locking protrusion 550 is inserted into the locking slot 540. Through the locking engagement of the locking block 510 and the locking slot 530, and the locking engagement of the locking protrusion 550 and the locking slot 540, the stability of the connection between the second rod and the second air duct wall 121 is improved, thereby improving the structural stability of the air conditioner indoor unit 100.

[0049] 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.

[0050] In this embodiment, the latching protrusion 550 is disposed on the latching block 510, and the latching groove 540 is disposed on the peripheral wall of the latching groove 530. Through the latching engagement between the latching block 510 and the latching groove 530, and the latching engagement between the latching protrusion 550 and the latching groove 540, the stability of the connection between the second rod and the second air duct wall 121 is improved, thereby improving the structural stability of the indoor unit 100 of the air conditioner.

[0051] In some embodiments of this utility model, such as Figure 5 As shown, the slot 530 is disposed on the side wall of the groove 520. A connecting block 560 is disposed between the locking block 510 and the corresponding support rod 310. The connecting block 560 contacts the side wall of the corresponding groove 520 during the process of the two support rods 310 merging.

[0052] In this embodiment, a connecting block 560 is provided between the support rod 310 and the locking block 510. When installing the support rod 310, the two support rods 310 are joined together, and the locking block 510 on the support rod 310 is inserted into the groove 520, so that the locking block 510 is inserted into the slot 530, and the locking protrusion 550 is inserted into the buckle slot 540. At the same time, the connecting block 560 contacts the side wall of the groove 520. The setting of the connecting block 560 increases the contact area between the support rod 310 and the wall of the air duct 20 when the support rod 310 supports the two walls of the air duct 20, thereby preventing the support rod 310 from shaking, improving the stability of the support rod 310 structure, and thus preventing the wall of the air duct 20 from bending, 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 2 As shown, after the support rod 310 is connected to the corresponding air duct 20 wall, the two support rods 310 are in a parallel state.

[0054] In this embodiment, after the support rods 310 are combined, they are in a parallel state. That is, the two support rods 310 simultaneously support the two walls of the air duct 20, and the two support rods 310 contact the same wall of the air duct 20 at different positions, thus supporting the walls of the air duct 20 at different locations. The two support rods 310 have a more stable supporting effect, thereby preventing the walls of the air duct 20 from bending and improving the structural stability of the indoor unit 100 of the air conditioner.

[0055] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the two support rods 310 are connected to the same air duct 20 wall.

[0056] In this embodiment, the two support rods 310 are connected to the same air duct 20 wall. When installing the support rods 310, it is only necessary to connect the two support rods 310 to one air duct 20 wall. The connection method is relatively convenient and facilitates the installation and disassembly of the indoor unit 100 of the air conditioner.

[0057] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the two air duct walls 20 are the first air duct wall 111 and the second air duct wall 121, respectively, and the two support rods 310 are both connected to the second air duct wall 121. The first air duct wall 111 is provided with two sliding grooves 410, and one end of each support rod 310 is inserted into a corresponding sliding groove 410 and contacts the bottom wall of the corresponding sliding groove 410.

[0058] In this embodiment, both support rods 310 are connected to the second air duct wall 121. The first air duct wall 111 has two sliding grooves 410, and the other end of each support rod 310 is inserted into one of the sliding grooves 410. When connecting the support rods 310 to the air duct wall 20, the two support rods 310 are joined together. The lower ends of the joined support rods 310 engage with the air duct wall 20, while the upper ends of the support rods 310 slide along the sliding grooves 410 and join together. When disassembling the support rods 310 from the air duct wall 20, the two support rods 310 are opened. The lower ends of the support rods 310 detach from the air duct wall 20, and the upper ends of the support rods 310 slide along the sliding grooves 410 and open. Both ends of the support rods 310 are detached from the air duct wall 20. The sliding groove 410 prevents the support rod 310 from tilting during opening or closing, restricts the support rod 310 from opening along the direction of the sliding groove 410, facilitates the installation and disassembly of the support rod 310, and thus facilitates the installation and disassembly of the indoor unit 100 of the air conditioner.

[0059] In some embodiments of this utility model, each slide 410 has a slot on its bottom wall, and one end of each support rod 310 is inserted into a corresponding slot.

[0060] In this embodiment, a slot is provided on the bottom wall of the slide 410. When the two support rods 310 are joined together, the support rods 310 are inserted into the slot. The slot fixes the support rods 310 to prevent them from moving, thereby improving the stability of the scissor support assembly 30 structure and thus improving the stability of the air conditioner indoor unit 100 structure.

[0061] In some embodiments of this utility model, such as Figure 1 , Figure 6 and Figure 7 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.

[0062] 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. 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 scissor-type support assembly 30 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.

[0063] In some embodiments of this utility model, such as Figure 7 As 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 is correspondingly positioned to the air duct 20. The front panel 610 also has an air inlet 630, located above the air outlet 620. The heat exchanger 640 is located on the upper side of the support frame 120, with its lower front end positioned within a water collection tray 660 on the splicing frame 110. The cross-flow fan 650 is rotatably mounted on the support frame 120. A scissor-type support assembly 30 is located at the front of the air duct 20.

[0064] 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 scissor-type support assembly 30 is located at the front of the air duct 20, and a cross-flow fan 650 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.

[0065] In some embodiments of this utility model, an elastic device is provided between the two support rods 310 to facilitate their merging. The two support rods 310 are rotatably connected by a pivot, and the elastic device is a torsion spring fitted onto the pivot.

[0066] In this embodiment, an elastic device, which is a torsion spring, is provided between the two support rods 310 and is fitted onto the rotating shaft. The elastic device causes the two support rods 310 to merge together. When the two ends of the support rods 310 support the wall of the air duct 20, the elasticity of the elastic device causes the two support rods 310 to merge together, preventing the two support rods 310 from tending to open outward when supporting the wall of the air duct 20, thereby improving the stability of the support structure and thus improving the stability of the indoor unit 100 structure of the air conditioner.

[0067] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
