[0035] The air conditioner indoor unit 10 of this utility model is described below with reference to the accompanying drawings.

[0036] like Figures 1-9 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention includes a support frame 100, a splicing frame 200, and a support rod 300.

[0037] The supporting frame 100 has a first frame body 110 and first frame ends 120, with the first frame ends 120 disposed at both ends of the first frame body 110. The splicing frame 200 has a second frame body 210 and second frame ends 220 disposed at both ends of the second frame body 210. The splicing frame 200 is detachably disposed on the upper side of the front end of the supporting frame 100. The two first frame ends 120 of the supporting frame 100 are spliced ​​and connected to the two second frame ends 220 of the splicing frame 200. The splicing frame 200 and the supporting frame 100 define an air outlet duct 400.

[0038] The support rod 300 is disposed within the air duct 400 and located at the front of the air duct 400. The lower end of the support rod 300 is connected to the support frame 100, and the upper end of the support rod 300 is connected to the splicing frame 200. Specifically, the upper end of the support rod 300 contacts and abuts against the splicing frame 200, and the lower end of the support rod 300 is fixedly connected to the support frame 100; alternatively, the upper end of the support rod 300 is fixedly connected to the splicing frame 200, and the lower end of the support rod 300 is fixedly connected to the support frame 100.

[0039] Compared with related technologies, the air conditioner indoor unit 10 of this utility model embodiment has a support between its support frame 100 and splicing frame 200, thereby using the support rod 300 to support the splicing frame 200, thus preventing the part between the two ends of the splicing frame 200 from bending and deforming due to gravity, improving the structural strength after the support frame 100 and splicing frame 200 are connected, and improving the user experience.

[0040] In some embodiments, the upper end of the support rod 300 is connected to the splicing frame 200 via a connecting structure 310, for example, the upper end of the support rod 300 is connected to the splicing frame 200 via a snap-fit ​​structure. The lower end of the support rod 300 is fixedly connected to the support frame 100, wherein the lower end of the support rod 300 can be fixed to the support frame 100 by screws or bolts; or, the support rod 300 and the support frame 100 are directly injection molded integrally.

[0041] The lower end of the support rod 300 is fixed to the support frame 100. When installing the support frame 100 and the splicing frame 200, the upper end of the support rod 300 is directly connected to the splicing frame 200 through the connecting structure 310, which makes it easier to install the support frame 100, the splicing frame 200 and the support rod 300, and improves the installation efficiency of the support frame 100, the splicing frame 200 and the support rod 300.

[0042] In other embodiments, the upper end of the support rod 300 is fixedly connected to the splicing frame 200, and the upper end of the support rod 300 can be fixed to the splicing frame 200 by screws or bolts; or, the support rod 300 and the splicing frame 200 are directly integrally injection molded. The lower end of the support rod 300 is connected to the support frame 100 through a connecting structure 310, for example, the lower end of the support rod 300 is connected to the support frame 100 through a snap-fit ​​structure.

[0043] The upper end of the support rod 300 is fixed to the support frame 100. When installing the support frame 100 and the splicing frame 200, the lower end of the support rod 300 is directly connected to the splicing frame 200 through the connecting structure 310, which makes it easier to install the support frame 100, the splicing frame 200 and the support rod 300, and improves the installation efficiency of the support frame 100, the splicing frame 200 and the support rod 300.

[0044] In some other embodiments, the upper end of the support rod 300 is connected to the splicing frame 200 via a connecting structure 310. For example, the upper end of the support rod 300 is connected to the splicing frame 200 via a snap-fit ​​structure. The lower end of the support rod 300 is connected to the support frame 100 via the connecting structure 310. For example, the lower end of the support rod 300 is connected to the support frame 100 via a snap-fit ​​structure. That is, both ends of the support rod 300 are connected to the splicing frame 200 and the support frame 100 respectively via the connecting structure 310, so as to facilitate the installation of the support rod 300 between the splicing frame 200 and the support frame 100, thereby improving the installation efficiency of the support frame 100, the splicing frame 200, and the support rod 300.

[0045] Furthermore, such as Figures 2-5 As shown, the connecting structure 310 includes a locking block 320, a groove 150, and a recess 150. The locking block 320 is disposed at a corresponding end of the support rod 300, and the groove 150 is disposed on the corresponding splicing frame 200 or support frame 100. That is, when the lower end of the support rod 300 is connected to the support frame 100 through the connecting structure 310, the locking block 320 is disposed at the upper end of the support rod 300, and the groove 150 is disposed on the splicing frame 200; or, when the upper end of the support rod 300 is connected to the splicing frame 200 through the connecting structure 310, the locking block 320 is disposed at the lower end of the support rod 300, and the groove 150 is disposed on the support frame 100.

[0046] One end of the support rod 300 is inserted into the groove 150, which is arranged such that the corresponding end of the support rod 300 and the locking block 320 can be inserted. A slot 160 is provided on the peripheral wall of the groove 150, and the locking block 320 is inserted into the slot 160. In other words, when the corresponding end of the support rod 300 is engaged with the splicing frame 200 or the support frame 100, the locking block 320 of the corresponding end of the support rod 300 is first inserted into the groove 150, and then the locking block 320 is pushed into the slot 160. This not only achieves the locking engagement between the support rod 300 and the splicing frame 200 or the support frame 100, but also not only allows the corresponding end of the support rod 300 to be inserted into the groove 150 to restrict the corresponding end of the support rod 300, but also makes the installation of the corresponding end of the support rod 300 and its corresponding splicing frame 200 or support frame 100 more stable through the engagement of the locking block 320 and the slot 160.

[0047] In some alternative embodiments, such as Figure 5As shown, the locking block 320 is provided with a locking groove 321, and the corresponding peripheral wall of the locking groove 160 is provided with a locking protrusion for inserting into the locking groove 321. That is to say, when the locking block 320 is engaged in the locking groove 321 on the locking block 320, the locking protrusion on the locking groove 160 engages with the locking protrusion on the locking groove 160, thereby further improving the stability of the engagement between the corresponding end of the support rod 300 and the corresponding splicing frame 200 or support frame 100.

[0048] Specifically, a latching groove 321 is provided on the surface of the latching block 320 facing the other end of the support rod 300. For example, when the lower end of the support rod 300 is engaged with the support frame 100, the upper surface of the latching block 320 is provided with a latching groove 321. The latching groove 160 includes a receiving groove 151 and a clearance groove 152. The latching block 320 is located in the receiving groove 151, and the clearance groove 152 is located on the side of the latching block 320 facing away from the other end of the support rod 300. In some optional embodiments, a latching protrusion is provided on the latching block 320, and a latching groove 321 for inserting the latching protrusion is provided on the corresponding peripheral wall of the latching groove 160. That is, when the latching block 320 is engaged in the latching groove 160, the latching protrusion on the latching block 320 engages with the latching groove 321 provided in the latching groove 160, thereby further improving the stability of the engagement between the corresponding end of the support rod 300 and the corresponding splicing frame 200 or support frame 100.

[0049] Specifically, a locking protrusion is provided on the surface of the locking block 320 facing the other end of the support rod 300. For example, when the lower end of the support rod 300 is engaged with the support frame 100, a locking protrusion is provided on the upper surface of the locking block 320.

[0050] In some embodiments, such as Figure 3 As shown, the groove 150 includes a receiving groove 151 and a clearance groove 152. The locking block 320 is located in the receiving groove 151, and the clearance groove 152 is located on the side of the locking block 320 opposite to the other end of the support rod 300. That is, the dimension of the slot 160 in the locking direction of the support rod 300 is larger than the overall dimension of the support rod 300 and the locking block 320, so that the support rod 300 and the locking block 320 can move along the locking direction after being inserted into the groove 150. This makes it easier to engage the locking block 320 into the slot 160 or remove the locking block 320 from the slot 160, thereby further facilitating the installation of the support rod 300 on the support frame 100 or the splicing frame 200 and improving assembly efficiency.

[0051] For example, Figure 3 and Figure 5As shown, the locking block 320 is disposed on the lower right side of the support rod 300, and the locking groove 160 is disposed on the right wall of the groove 150. The dimension of the groove 150 in the left-right direction is larger than the dimension of the overall structure formed by the lower end of the support rod 300 and the locking block 320 in the left-right direction, so that the lower end of the support rod 300 and the locking block 320 can move in the left-right direction after being inserted into the groove 150.

[0052] In some embodiments, such as Figures 7-8 As shown, the first frame end 120 has a first splicing surface 121, and the first splicing surface 121 is perpendicular to the length direction of the first frame body 110 (e.g., Figure 1 The second frame end 220 has a second splicing surface 221, which is parallel to the length direction of the second frame body 210 (e.g., the left-right direction). Figure 1 The first splicing surface 121 and the second splicing surface 221 are arranged opposite each other, and a sealing gasket 500 is provided between the first splicing surface 121 and the second splicing surface 221. When the splicing frame 200 is installed on the supporting frame 100, the first splicing surface 121 and the second splicing surface 221 are opposite each other. The sealing gasket 500 fills the splicing seam formed between the first splicing surface 121 and the second splicing surface 221, thereby sealing the splicing seam formed between the splicing frame 200 and the supporting frame 100.

[0053] In other words, a sealing gasket 500 is provided between the first splicing surface 121 and the second splicing surface 221 to seal the gap formed between the first splicing surface 121 and the second splicing surface 221, thereby preventing airflow in the air duct 400 from leaking from the gap and condensation from forming at the gap, thus improving the user experience.

[0054] In some embodiments, such as Figures 7-9 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention also includes a front panel 610, a heat exchanger 620, a cross-flow fan 630 and a motor 640.

[0055] An air outlet 611 is provided on the front panel 610; the front panel 610 is detachably mounted on the front side of the splicing frame 200 and the supporting frame 100, and the air outlet 611 is correspondingly arranged with the air duct 400. A heat exchanger 620 is located on the upper side of the supporting frame 100; the lower front end of the heat exchanger 620 is located in a water collection tank on the splicing frame 200; the front panel 610 also has an air inlet, which is located above the air outlet 611, so that airflow passes through the air inlet and the upper side of the splicing frame 200, flows through the heat exchanger 620, and then flows out through the air duct 400 and the air outlet 611. A cross-flow fan 630 is rotatably mounted on the supporting frame 100, and a motor 640 is mounted on the supporting frame 100. The motor 640 is connected to the cross-flow fan 630 to drive the cross-flow fan 630 to rotate. When the fan needs maintenance or replacement, the operator can remove the front panel 610 and then simply remove the splicing frame 200 from the indoor unit 10 of the air conditioner to install or remove the fan, making the fan maintenance more convenient and improving the user experience.

[0056] In some embodiments, such as Figures 7-9 As shown, the splicing frame 200 has a volute structure that mates with the cross-flow impeller 630, and the supporting frame 100 has a volute structure that mates with the cross-flow impeller 630. Thus, the splicing frame 200 and the supporting frame 100 respectively form the volute structure and the volute structure, thereby forming the air duct 400. Because the supporting rod 300 connects the splicing frame 200 and the supporting frame 100, the air duct 400 is less prone to deformation, ensuring that the air duct 400 can output air normally.

[0057] In some embodiments, such as Figure 1 As shown, the support rod 300 is positioned at the air outlet 611, preventing the air outlet 611 from deforming and ensuring normal airflow. The air outlet 611 extends in the left-right direction, and there can be one or more support rods 300. When there is only one support rod 300, it is positioned at the center of the air outlet 611; when there are multiple support rods 300, they are spaced apart in the left-right direction at the air outlet 611.

[0058] In some embodiments, such as Figures 7-9As shown, the indoor unit 10 of this embodiment of the air conditioner also includes a motor 640 mount. The motor 640 is mounted on the motor 640 mount and is detachably mounted on the support frame 100. The motor 640 mount is provided with a snap-fit ​​component and a mounting through hole. The snap-fit ​​component is located at the upper rear end of the motor 640 mount, and the mounting through hole is located at the bottom of the motor 640 mount. The support frame 100 is provided with a snap-fit ​​groove that mates with the snap-fit ​​component and a threaded hole that aligns with the mounting through hole. The mounting through hole is located in front of the threaded hole and is engaged with the snap-fit ​​groove by the snap-fit ​​component and connected to the mounting through hole and the threaded hole by a threaded connector, so that the motor 640 mount can be detachably mounted on the support frame 100. Thus, the motor 640 is fixedly mounted on the end 120 of the first frame using the motor 640 mount, facilitating assembly and disassembly.

[0059] 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.
