[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 sealing gasket 300.

[0037] The supporting frame 100 has a first frame body 110 and first frame end pieces 120 disposed at both ends of the first frame body 110. The first frame end pieces 120 have a first splicing surface 130, which is parallel to the length direction of the first frame body 110. The splicing frame 200 has a second frame body 210 and second frame end pieces 220 disposed at both ends of the second frame body 210. The second frame end pieces 220 have a second splicing surface 230, which is parallel to the length direction of the second frame body 210.

[0038] The splicing frame 200 is disposed on one side of the supporting frame 100, for example, on the upper side of the supporting frame 100. The splicing frame 200 and the supporting frame 100 define the air outlet duct, and the first splicing surface 130 and the second splicing surface 230 are disposed opposite to each other. The splicing frame 200 can be directly installed on the supporting frame 100 via a connecting structure; alternatively, two fixing structures are provided inside the air conditioner indoor unit 10, and the splicing frame 200 and the supporting frame 100 are respectively installed inside the air conditioner indoor unit 10 via corresponding fixing structures, with the splicing frame 200 located on that side of the supporting frame 100.

[0039] A sealing gasket 300 is disposed between the first splicing surface 130 and the second splicing surface 230. That is, when the splicing frame 200 is installed on the supporting frame 100, the first splicing surface 130 and the second splicing surface 230 are opposite each other. The sealing gasket 300 fills the splicing seam formed between the first splicing surface 130 and the second splicing surface 230, thereby sealing the splicing seam formed between the splicing frame 200 and the supporting frame 100.

[0040] Compared with related technologies, the indoor unit 10 of this utility model has a splicing frame 200 disposed on one side of a supporting frame 100. The supporting frame 100 and the splicing frame 200 each have a first splicing surface 130 and a second splicing surface 230 disposed opposite to each other. A sealing gasket 300 is disposed between the first splicing surface 130 and the second splicing surface 230 to seal the gap formed between the first splicing surface 130 and the second splicing surface 230, thereby preventing airflow in the duct from leaking from the gap and preventing condensation from forming at the gap, thus improving the user experience.

[0041] Optionally, the sealing gasket 300 may be made of polyurethane foam; the sealing gasket 300 may also be made of rubber; or the sealing gasket 300 may also be made of other sealing materials.

[0042] like Figures 1-10 As shown, the indoor unit 10 of this utility model embodiment includes a front panel 400, a heat exchanger 500, a cross-flow fan 600, a motor 700, a support frame 100, a splicing frame 200, and a sealing gasket 300. The indoor unit 10 of this utility model embodiment can be a recessed indoor unit 10.

[0043] An air outlet 410 is provided on the front panel 400. The splicing frame 200 is located on the upper side of the front end of the support frame 100 and is detachably installed on the support frame 100. The front panel 400 is detachably installed on the front side of the splicing frame 200 and the support frame 100, with the air outlet 410 corresponding to the air duct. A heat exchanger 500 is located on the upper side of the support frame 100, with its lower front end positioned within a water collection tank 240 on the splicing frame 200. An air inlet is also provided on the front panel 400, located above the air outlet 410, allowing airflow to pass through the air inlet and the upper side of the splicing frame 200, through the heat exchanger 500, and then out through the air duct and the air outlet 410. A cross-flow fan 600 is rotatably installed on the support frame 100. The motor 700 is mounted on the support frame 100 and is connected to the cross-flow fan 600 to drive the cross-flow fan 600 to rotate.

[0044] When the fan needs maintenance or replacement, the operator can remove the front panel 400 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.

[0045] In some embodiments, the width of the first splicing surface 130 is 3 to 8 mm, and the width of the second splicing surface 230 is 3 to 8 mm. That is, the width of the first splicing surface 130 includes, but is not limited to, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, or 8 mm. The width of the second splicing surface 230 includes, but is not limited to, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, or 8 mm. For example, when the width of the first splicing surface 130 is designed to be 4 mm, the width of the second splicing surface 230 is less than 4 mm. This makes the first splicing surface 130 and the second splicing surface 230 more tolerant of errors during assembly, allowing for a certain positional deviation between the first splicing surface 130 and the second splicing surface 230, thereby reducing the alignment accuracy requirements of the first splicing surface 130 and the second splicing surface 230, thus saving the installation time and manufacturing cost of the support frame 100 and the splicing frame 200 in this embodiment.

[0046] Furthermore, the width of the first splicing surface 130 is greater than or equal to the width of the second splicing surface 230. Optionally, the ratio between the width of the first splicing surface 130 and the width of the second splicing surface 230 is 1 to 1.5. Optionally, the ratio between the width of the first splicing surface 130 and the width of the second splicing surface 230 is 1.1 to 1.4. Optionally, the ratio between the width of the first splicing surface 130 and the width of the second splicing surface 230 is 1.2 to 1.3. That is to say, the first splicing surface 130 has a larger size, thereby increasing the contact area of ​​the first splicing surface 130 and thus enhancing the support stability of the support frame 100.

[0047] The ratio between the width of the first splicing surface 130 and the width of the second splicing surface 230 is, but is not limited to, 1, 1.1, 1.2, 1.3, 1.4 or 1.5.

[0048] In some embodiments, the inner edge of the first splicing surface 130 is aligned with the inner edge of the second splicing surface 230. Alignment of the inner edges of the first splicing surface 130 and the second splicing surface 230 ensures that the sealing gasket 300 is subjected to uniform pressure, avoids local gaps between the first splicing surface 130 and the second splicing surface 230 and excessive compression of the sealing gasket 300, thereby improving sealing reliability.

[0049] In some embodiments, such as Figure 6 As shown, a baffle 121 is provided on the outer side of each first frame end 120, and two second frame ends 220 are located between the two baffles 121. Each second frame end 220 contacts and abuts against the inner surface of the corresponding baffle 121.

[0050] Specifically, the two first frame ends 120 are spaced apart laterally, and each of the two first frame ends 120 is provided with a baffle 121. The two second frame ends 220 are located laterally between the two baffles 121, and the outer surfaces of the two second frame ends 220 respectively contact and abut against the inner surfaces of the two baffles 121. That is to say, the support frame 100 positions the splicing frame 200 laterally through the two baffles 121, so that the splicing frame 200 is confined between the two baffles 121. When assembling the support frame 100 and the splicing frame 200, it is convenient to position the splicing frame 200, thereby improving the assembly efficiency of the support frame 100 and the splicing frame 200.

[0051] Furthermore, such as Figures 4-8 As shown, each baffle 121 is connected to the corresponding first frame end 120 via a connecting plate 122. The surface of the connecting plate 122 facing the splicing frame 200 is on the same plane as the first splicing surface 130. A flange 231 is provided at the outer edge of the second splicing surface 230. The flange 231 has a notch 232 that matches the connecting plate 122, and the connecting plate 122 is inserted into the notch 232. The supporting frame 100 positions the flange 231 of the splicing frame 200 in the front-back direction via the connecting plate 122. This facilitates the positioning of the splicing frame 200 during the assembly of the supporting frame 100 and the splicing frame 200, thereby improving the assembly efficiency of the supporting frame 100 and the splicing frame 200.

[0052] In some embodiments, such as Figure 9 As shown, the indoor unit 10 of this embodiment of the air conditioner also includes a motor mount 800, on which the motor 700 is mounted. The motor mount 800 is detachably mounted on the first frame body 110, and the motor mount 800 is located on the outside of one end 120 of the first frame. Thus, the motor 700 is fixedly mounted on the end 120 of the first frame using the motor mount 800, which facilitates disassembly and assembly.

[0053] In some embodiments, the first frame body 110 is provided with a first mounting portion 111 and a second mounting portion 112, which are spaced apart. The motor mount 800 is provided with a first connecting portion 810 and a second connecting portion 820. The first connecting portion 810 is engaged with the first mounting portion 111, and the second connecting portion 820 is fixedly connected to the second mounting portion 112. That is, when installing the motor mount 800, the operator can first engage the first connecting portion 810 with the first mounting portion 111 so that the first frame body 110 positions the motor mount 800 through the positioning structure, thereby facilitating the fixed connection of the second connecting portion 820 to the second mounting portion 112, thus making the installation of the motor mount 800 easier.

[0054] Specifically, one of the first connecting portion 810 and the first mounting portion 111 has a bent fastening element, and the other of the first connecting portion 810 and the first mounting portion 111 has a snap-fit ​​groove that mates with the fastening element. That is, the first connecting portion 810 has a bent fastening element, and the first mounting portion 111 has a snap-fit ​​groove that mates with the fastening element. Alternatively, the first mounting portion 111 has a bent fastening element, and the first connecting portion 810 has a snap-fit ​​groove that mates with the fastening element.

[0055] The second connecting part 820 is provided with a mounting through hole, and the second mounting part 112 is provided with a threaded hole. The mounting through hole corresponds to the threaded hole, and the mounting through hole is located in front of the threaded hole. It is connected to the mounting through hole and the threaded hole through a first threaded connector, so that the second connecting part 820 and the second mounting part 112 are fixedly connected. The first threaded connector is a screw or bolt assembly. The first mounting part 111 is located on the upper side of the second mounting part 112, which facilitates the installation of the first threaded connector in the mounting through hole and the threaded hole, thus making it easier to install the motor base 800.

[0056] In other embodiments, such as Figure 9 As shown, the first connecting part 810 and the first mounting part 111, as well as the second connecting part 820 and the second mounting part 112, are all fixedly connected by screws or bolts, thereby simplifying the structure of the motor base 800 and the support frame 100 and reducing manufacturing costs.

[0057] In some embodiments, the motor mount 800 includes a front housing, a first rear housing, and a second rear housing. The front housing has a rearward-opening receiving cavity, and a second connecting portion 820 is disposed at the lower part of the front housing. The first rear housing is disposed at the rear side of one end of the front housing in the lateral direction, and the front housing and the first rear housing are configured to fix one end of the motor 700 in the lateral direction. The second rear housing is disposed at the rear side of the other end of the front housing in the lateral direction, and the front housing and the second rear housing are configured to fix the other end of the motor 700 in the lateral direction. Thus, the motor 700 is fixed to the support frame 100 by the front housing, the first rear housing, and the second rear housing, reducing the contact area between the motor mount 800 and the support frame 100, thereby reducing noise generated by vibration between the motor mount 800 and the support frame 100 during motor 700 operation.

[0058] Specifically, the upper part of the front shell is provided with a first connecting part 810; the upper part of the first rear shell is snapped into the front shell, and the lower part of the first rear shell is connected to the front shell via a second threaded connector; the second threaded connector passes through the lower part of the first rear shell and is threadedly connected to the front shell. The first connecting part 810 on the front shell is located on the rear side of the upper part of the first rear shell. The lower part of the second rear shell is snapped into the front shell, and the upper part of the second rear shell is connected to the front shell via a third threaded connector. The third threaded connector passes through the upper part of the second rear shell and is threadedly connected to the front shell, and the upper part of the second rear shell is provided with the first connecting part 810.

[0059] A first rubber component is provided at one end of the motor 700 in the lateral direction, positioned between the front housing and the first rear housing. A second rubber component is provided at the other end of the motor 700 in the lateral direction, positioned between the front housing and the second rear housing. The first and second rubber components, respectively positioned between the front housing and the first rear housing and between the front housing and the second rear housing, serve to dampen vibrations in the motor 700, thereby further reducing the noise generated during motor operation.

[0060] 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. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
