[0040] The air conditioner indoor unit 10 of this utility model is described below with reference to the accompanying drawings.

[0041] like Figures 1-8 As shown, the indoor unit 10 of the air conditioner in this embodiment of the present invention includes a first frame 100, a second frame 200 and a heat exchanger 300.

[0042] The second frame 200 is disposed inside the first frame 100, and an air outlet duct is defined between the first frame 100 and the second frame 200. The heat exchanger 300 is connected between the first frame 100 and the second frame 200 so that the airflow in the air outlet duct can pass through the heat exchanger 300 and exchange heat with the heat exchanger 300.

[0043] The heat exchanger 300 includes a heat exchange section 310 and a tube sheet 320. The heat exchange section 310 is configured to exchange heat with the airflow flowing through it; that is, the airflow exchanges heat with the heat exchange section 310 as it flows through it. There are two tube sheets 320, which are sequentially arranged at one end of the heat exchange section 310 along an inward-outward direction, and are centrally symmetrical. Each tube sheet 320 has a mounting structure on its side. The mounting structure of the outer tube sheet 320 is mounted on the first frame 100, and the mounting structure of the inner tube sheet 320 is mounted on or abuts against the second frame 200.

[0044] In other words, the two tube sheets 320 have identical structures. One tube sheet 320 is disposed outside the other tube sheet 320. Since the two tube sheets 320 are centrally symmetrically arranged, the mounting structure of the outer tube sheet 320 is located on its outer side, and the mounting structure of the inner tube sheet 320 is located on its inner side. Thus, the outer tube sheet 320 is mounted on the first frame 100 through its mounting structure, and the inner tube sheet 320 is mounted on the second frame 200 or contacts and abuts against the second frame 200 through its mounting structure, so that the two tube sheets 320 are disposed at one end of the heat exchange section 310.

[0045] Compared with related technologies, the indoor unit 10 of this utility model includes a first frame 100, a second frame 200, and a heat exchanger 300. Two tube sheets 320 are provided at one end of the heat exchange section 310 of the heat exchanger 300. The two tube sheets 320 are centrally symmetrically arranged, and the two tube sheets 320 are mounted on the first frame 100 via corresponding mounting structures, while the inner tube sheet 320 is mounted on or abuts against the second frame 200 via its mounting structure. Since the two tube sheets 320 have identical structures, there is no need to further distinguish their structures during installation, simplifying the assembly steps of the heat exchanger 300 and thus improving the production efficiency of the indoor unit 10 of this utility model.

[0046] Furthermore, since the two tube sheets 320 have identical structures, there is no need to use two different molds for manufacturing, thus reducing mold opening costs.

[0047] In some embodiments, such as Figures 2-5 As shown, the two tube sheets 320 include a first tube sheet 330 and a second tube sheet 340. The first tube sheet 330 includes a first plate body 331 and a first flange 332 connected to the outside of the first plate body 331, and the first flange 332 is mounted on the first frame 100. The second tube sheet 340 includes a second plate body 341 and a second flange 342 connected to the inside of the second plate body 341, and the second flange 342 is mounted on the second frame 200 or contacts and abuts against the second frame 200.

[0048] In other words, the first flange 332 serves as the mounting structure for the first tube sheet 330, and the second flange 342 serves as the mounting structure for the second tube sheet 340. The first tube sheet 330 is fixed to the surface of the first frame 100 via the first flange 332, increasing the contact area between the first tube sheet 330 and the surface of the first frame 100, thereby preventing air leakage at the contact point. Similarly, the second tube sheet 340 is fixed to the surface of the second frame 200 or contacts and abuts against the surface of the second frame 200 via the second flange 342, increasing the contact area between the second tube sheet 340 and the surface of the second frame 200, thereby preventing air leakage at the contact point.

[0049] Specifically, the first flange 332 is perpendicular to the first plate 331, and the second flange 342 is perpendicular to the second plate 341. That is to say, the outer contour of the cross-section of the first tube plate 330 and the second tube plate 340 is L-shaped, which makes the structural strength of the first tube plate 330 and the second tube plate 340 stronger and improves the load-bearing capacity of the first tube plate 330 and the second tube plate 340.

[0050] Furthermore, the first flange 332 is located on the side of the first plate 331 opposite to the heat exchange section 310, and the second flange 342 is located on the side of the second plate 341 opposite to the heat exchange section 310. By placing the first flange 332 on the side of the first plate 331 opposite to the heat exchange section 310 and the second flange 342 on the side of the second plate 341 opposite to the heat exchange section 310, the installation interference of the first flange 332 and the second flange 342 on the heat exchange section 310 is avoided, making the heat exchange section 310 more tightly installed with other components and reducing the overall size of the air conditioner indoor unit 10 in this embodiment.

[0051] In some embodiments, a plurality of through holes are spaced apart along the length of the first flange 332, and a plurality of threaded holes corresponding to the plurality of through holes are provided on the surface of the first frame 100. A threaded connector passes through the through holes and engages with the threaded holes to fix the first tube body onto the first frame 100.

[0052] In some embodiments, the second flange 342 is provided with a plurality of through holes spaced apart along its length, and the surface of the second frame 200 is provided with a plurality of threaded holes corresponding to the plurality of through holes. A threaded connector passes through the through holes and engages with the threaded holes to fix the second tube body onto the second frame 200.

[0053] In some embodiments, such as Figure 9 As shown, the first plate 331 is provided with a plurality of first mounting through holes 333, and the second plate 341 is provided with a plurality of second mounting through holes 343. The heat exchanger 300 also includes a first bent tube portion 351 and a second bent tube portion 352 disposed at one end of the heat exchange section 310. The two ends of the first bent tube portion 351 are respectively inserted into two adjacent first mounting through holes 333, and the two ends of the second bent tube portion 352 are respectively inserted into two adjacent second mounting through holes 343. The air conditioning indoor unit 10 also includes a cable tie 400, which is tied to the adjacent first bent tube portion 351 and second bent tube portion 352 and is located on the side of the first plate 331 and the second plate 341 away from the heat exchange section 310.

[0054] In other words, the first tube sheet 330 is fixedly mounted on the first frame 100, and the second tube sheet 340 is bound to the first bend 351 and the second bend 352 by cable ties 400 to prevent the second tube sheet 340 from coming out of the second bend 352. Furthermore, the second flange 342 of the second tube sheet 340 contacts and abuts against the surface of the second frame 200, thereby preventing the second tube sheet 340 from wobbling in the inward and outward directions. This ensures that the second tube sheet 340 is stably mounted on one end of the heat exchange section 310, and the installation and operation are convenient.

[0055] Furthermore, the indoor unit 10 of the air conditioner in this embodiment of the present invention also includes a sealing gasket 210, which is disposed between the second flange 342 and the second frame 200. That is, the sealing gasket 210 is used to seal the gap between the second flange 342 and the second frame 200 to prevent air leakage between the second flange 342 and the second frame 200.

[0056] Optionally, the sealing gasket 210 may be made of rubber; or the sealing gasket 210 may also be made of polyurethane; or the sealing gasket 210 may also be made of other sealing materials.

[0057] In some embodiments, such as Figure 4 and Figure 5As shown, the first frame 100 includes a first end 110, a second end 120, and a connecting portion 130 connecting the first end 110 and the second end 120. The first end 110 has a first abutment portion 111, and the surface of one end of the first tube sheet 330 facing the heat exchange portion 310 contacts the first abutment portion 111. The second end 120 has a second abutment portion 121, and the surface of the second tube sheet 340 at the end away from the first end 110 facing the heat exchange portion 310 contacts the second abutment portion 121.

[0058] Specifically, the first end 110 has a first abutment portion 111, and the second end 120 has a second abutment portion 121. The lengths of the first tube sheet 330 and the second tube sheet 340 are both greater than the length of the heat exchange section 310. The end of the first tube sheet 330 away from the second end 120 extends beyond the heat exchange section 310, and the end of the second tube sheet 340 away from the first end 110 also extends beyond the heat exchange section 310. The portions of the first tube sheet 330 and the second tube sheet 340 extending beyond the heat exchange section 310 respectively abut against the first abutment portion 111 and the second abutment portion 121, so that the first tube sheet 330 and the second tube sheet 340 both contact the first frame 100 through a plane-to-plane abutment, preventing the heat exchanger 300 from shaking under force, thereby making the heat exchanger 300 more securely fixed and reducing the risk of damage to the heat exchanger 300.

[0059] In some alternative embodiments, the first abutment portion 111 is a portion of the surface area of ​​the first frame 100. A first protrusion is provided on the first abutment portion 111, and a first groove or first through hole is provided on the portion of the first tube sheet 330 away from the second end 120. The first protrusion is inserted into the first groove or first through hole. The engagement of the first protrusion with the first groove or first through hole further restricts the movement of the first tube sheet 330, thereby enabling the first tube sheet 330 to be more stably mounted on the first frame 100.

[0060] In some alternative embodiments, the first abutment 111 is a first protrusion, and a first abutment groove is provided on the portion of the first tube sheet 330 away from the second end 120. The first protrusion is inserted into the first abutment groove and contacts and abuts against the first abutment groove. By engaging the first abutment 111 with the first abutment groove, the movement of the first tube sheet 330 is further restricted, thereby enabling the first tube sheet 330 to be more stably mounted on the first frame 100.

[0061] In some alternative embodiments, the second abutment 121 is a portion of the surface area of ​​the first frame 100. A second protrusion is provided on the second abutment 121, and a second groove or second through hole is provided on the portion of the second tube sheet 340 away from the first end 110. The second protrusion is inserted into the second groove or second through hole. The engagement of the second protrusion with the second groove or second through hole further restricts the movement of the second tube sheet 340, thereby enabling the second tube sheet 340 to be installed more stably.

[0062] In some alternative embodiments, the second abutment 121 is a second protrusion, and a second abutment groove is provided on the portion of the second tube sheet 340 away from the first end 110. The second protrusion is inserted into the second abutment groove and contacts and abuts against the second abutment groove. By cooperating with the second abutment 121 and the second abutment groove, the movement of the second tube sheet 340 is further restricted, thereby enabling the second tube sheet 340 to be installed more stably.

[0063] In some embodiments, such as Figure 6 As shown, the first end plate 110 has a first rib 112 and a second rib 113, both extending along the length of the first tube sheet 330. The first rib 112 contacts and abuts against the first plate 331, and the second rib 113 contacts and abuts against the first flange 332. After the heat exchanger 300 is installed, the first rib 112 and the second rib 113 can jointly support the first tube sheet 330. The first rib 112 and the second rib 113 enhance the compressive strength of the first end plate, thereby improving the structural stability of the first end plate and making the heat exchanger 300 more securely fixed.

[0064] In some embodiments, such as Figure 6 As shown, a grounding screw hole 334 is provided on the first flange 332, and a through hole 131 is provided on the first frame 100 at a position corresponding to the grounding screw hole 334; the through hole 131 is provided on the side of the first flange 332 facing away from the first tube sheet 330. When assembling the heat exchanger 300, the grounding screw passes through the first grounding screw hole 334 and the through hole 131. The grounding setting of the heat exchanger 300 prevents damage to the indoor unit of the air conditioner 20 caused by static electricity accumulation and overvoltage, helps to maintain the voltage stability of the indoor unit of the air conditioner 20, reduces the impact of voltage fluctuations on the indoor unit of the air conditioner 20, and thus improves the safety performance and service life of the indoor unit of the air conditioner 20.

[0065] like Figure 10As shown, the air conditioner 20 of this embodiment includes the indoor unit 10 of any of the above-mentioned features. In the indoor unit 10 of the air conditioner 20 of this embodiment, the heat exchange section 310 of the heat exchanger 300 is provided with two tube sheets 320, and the two tube sheets 320 are arranged symmetrically at the center. Since the two tube sheets 320 have identical structures, there is no need to further distinguish the structures of the two tube sheets 320 when installing them, simplifying the assembly steps of the heat exchanger 300, increasing the production efficiency of the indoor unit 10, and thus improving the installation efficiency of the air conditioner 20 of this embodiment.

[0066] 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.
