[0034] The embodiment of the present application provides an air conditioner indoor unit, as Figures 1 to 12As shown in the figure, the indoor air conditioner includes a base 100, a motor 200, and a mounting assembly. A rear boss 210 is provided at the rear end of the shaft of the motor 200, and the mounting assembly is detachably connected to the base 100. The mounting assembly includes a first mounting plate 310 provided with a first notch 311 and a second mounting plate 320 provided with a second notch 321. The first notch 311 and the second notch 321 are combined to form a positioning hole, and the rear boss 210 is clamped in the positioning hole. A first sliding portion 312 extending along the depth direction of the first notch 311 is provided on the first mounting plate 310, and a second sliding portion 322 extending along the depth direction of the second notch 321 is provided on the second mounting plate 320. The first sliding portion 312 and the second sliding portion 322 are in sliding fit. Herein, the rear end of the shaft of the motor 200 refers to the end of the motor 200 away from the motor shaft 230.

[0035] For the indoor air conditioner provided by the embodiment of the present application, a detachable mounting assembly is provided on the base 100. The mounting assembly includes a first mounting plate 310 and a second mounting plate 320. The first mounting plate 310 is provided with a first notch 311 and a first sliding portion 312 extending along the depth direction of the first notch 311. The second mounting plate 320 is provided with a second notch 321 and a second sliding portion 322 extending along the depth direction of the second notch 321. The rear boss 210 of the motor 200 is clamped in the positioning hole formed by the combination of the first notch 311 and the second notch 321, and the first sliding portion 312 and the second sliding portion 322 are in sliding fit. By adopting the structure of sliding assembly of the first mounting plate 310 and the second mounting plate 320, the installation and disassembly of the motor 200 can be very conveniently completed in a limited space.

[0036] Specifically, when it is necessary to install the motor 200 on the base 100, the second mounting plate 320 can be first arranged on the base 100, and then the rear boss 210 of the motor 200 can be snapped into the second notch 321. Then, through the cooperation of the first sliding portion 312 and the second sliding portion 322, the first mounting plate 310 is slidably assembled on the second mounting plate 320, so that the first notch 311 and the second notch 321 are combined to form a positioning hole, and the rear boss 210 of the motor 200 is clamped in the positioning hole, thereby realizing the installation of the motor 200, and the installation operation is convenient. When it is necessary to remove the motor 200 from the base 100, the first mounting plate 310 can be first slid relative to the second mounting plate 320 to cancel its assembly with the second mounting plate 320. Then, after the second mounting plate 320 is removed, the motor 200 can be removed from the base 100. Compared with the existing indoor air conditioner of an air conditioner, when disassembling the motor 200 of the present application, it is not necessary to disassemble the end cover of the motor 200 and the indoor heat exchanger 500, and the operation is more convenient.

[0037] In some embodiments of the present application, such as Figures 8 to 12As shown, the first mounting plate 310 is further provided with an assembly notch 313 communicating with the first notch 311. Both side walls of the assembly notch 313 are provided with first sliding portions 312. On both sides of the second mounting plate 320 along the depth direction of the second notch 321, second sliding portions 322 are provided. The second sliding portions 322 on both sides are in sliding fit with the first sliding portions 312 on both sides in a one-to-one correspondence. With such a setting, the space occupied by the first sliding portion 312 and the second sliding portion 322 in the axial direction of the motor shaft 230 can be reduced, and at the same time, the assembly structure of the first mounting plate 310 and the second mounting plate 320 is more stable.

[0038] Optionally, both the first sliding portion 312 and the second sliding portion 322 are rib structures, and the thickness of the first sliding portion 312 is less than the thickness of the first mounting plate 310, so that the first sliding portion 312 and the first mounting plate 310 form a first stepped structure; the thickness of the second sliding portion 322 is less than the thickness of the second mounting plate 320, so that the second sliding portion 322 and the second mounting plate 320 form a second stepped structure. Among them, the stepped surface of the first stepped structure is attached to the stepped surface of the second stepped structure and can slide relative to each other, thereby realizing the sliding assembly of the first mounting plate 310 and the second mounting plate 320.

[0039] Or, in other embodiments, one of the first sliding portion 312 and the second sliding portion 322 is a chute, and the other is a sliding protrusion. The sliding protrusion is inserted into the chute and can slide along the chute, so that the sliding assembly of the first mounting plate 310 and the second mounting plate 320 can also be realized.

[0040] Optionally, one end of the first sliding portion 312 close to the opening of the first notch 311 is provided with a first guiding surface 314, and one end of the second sliding portion 322 close to the opening of the second notch 321 is provided with a second guiding surface 323. The first guiding surface 314 and the second guiding surface 323 are used to guide the sliding fit of the first sliding portion 312 and the second sliding portion 322, so as to facilitate the sliding assembly of the first mounting plate 310 and the second mounting plate 320.

[0041] In some embodiments of the present application, as Figures 8 to 12 shown, the bottom of the first notch 311 is provided with a third notch 315 communicating with the first notch 311, and the bottom of the second notch 321 is provided with a fourth notch 324 communicating with the second notch 321. On two opposite sides of the rear boss 210, a first protrusion 211 and a second protrusion 212 are respectively provided. The first protrusion 211 and the second protrusion 212 are respectively clamped in the third notch 315 and the fourth notch 324, so that the installation and positioning of the motor 200 are more stable.

[0042] Optionally, in combination with Figure 5 and Figure 11As shown in the figure, a positioning groove 325 is provided on the edge of the second mounting plate 320 opposite to the second notch 321, and a positioning protrusion 110 is provided on the base 100. The positioning protrusion 110 is in concave-convex fit with the positioning groove 325; alternatively, a positioning groove 325 is provided on the base 100, and a positioning protrusion 110 is provided on the edge of the second mounting plate 320 opposite to the second notch 321. The positioning protrusion 110 is in concave-convex fit with the positioning groove 325. By providing the positioning groove 325 and the positioning protrusion 110, it is convenient to install the second mounting plate 320 on the base 100, and at the same time, it can also prevent the second mounting plate 320 from moving in the circumferential direction of the motor 200 (i.e., limit the freedom degree of the second mounting plate 320 in the circumferential direction of the motor 200), so that the installation and positioning of the motor 200 are more stable.

[0043] In some embodiments of the present application, as Figures 8 to 10 shown, connection portions 316 are provided on both sides of the first notch 311 of the first mounting plate 310. The connection portions 316 are detachably connected to the base 100, thereby realizing detachably arranging the first mounting plate 310 on the base 100, which is convenient for disassembling and assembling the first mounting plate 310, and further convenient for disassembling and assembling the motor 200.

[0044] Optionally, in combination with Figure 6 and Figure 8 shown, mounting holes 317 are provided on the connection portions 316, and threaded holes 120 are provided on the base 100. The mounting holes 317 and the threaded holes 120 are connected by threaded fasteners (such as screws or bolts). That is to say, the connection portions 316 and the base 100 are connected by threaded fasteners sequentially passing through the mounting holes 317 and the threaded holes 120, thereby realizing the detachable connection between the first mounting plate 310 and the base 100, being convenient for disassembling and assembling the first mounting plate 310, and at the same time making the installation and positioning of the motor 200 more stable.

[0045] Specifically, when disassembling the motor 200, as Figure 4 shown, first remove the screw connecting the first mounting plate 310 and the base 100, then slide the first mounting plate 310 upward, and after separating from the rear boss 210 of the motor 200, the first mounting plate 310 can be taken out; after taking out the first mounting plate 310, the motor 200 is in a loose state. At this time, the second mounting plate 320 can be directly taken out from the base 100, and finally the motor 200 can be taken off the base 100. When installing the motor 200, as Figure 5 shown, first align the positioning groove 325 on the second mounting plate 320 with the positioning groove 325 on the base 100 and make them in concave-convex fit to position the second mounting plate 320 on the base 100, and then insert the lower half of the rear boss 210 of the motor 200 into the second notch 321 of the second mounting plate 320; as Figure 4As shown in the figure, then slide the first mounting plate 310 downward from top to bottom until it reaches the bottom, so that the upper half of the rear boss 210 of the motor 200 is snapped into the first notch 311. Finally, connect the first mounting plate 310 to the base 100 with screws and lock them to complete the installation of the motor 200.

[0046] In other embodiments, the connecting portion 316 on the first mounting plate 310 can also be snap-connected to the base 100, which can also achieve detachably setting the first mounting plate 310 on the base 100.

[0047] In some embodiments of the present application, a stop portion 130 is provided at one end of the base 100 along the motor shaft 230 direction. The stop portion 130 is used to stop on the outer sides of the first mounting plate 310 and the second mounting plate 320 (that is, the sides of the first mounting plate 310 and the second mounting plate away from the front end of the motor shaft 230). Thus, the stop portion 130 can be used to stop on the outer sides of the first mounting plate 310 and the second mounting plate 320 to limit the degrees of freedom of the first mounting plate 310 and the second mounting plate 320 in the direction of the motor shaft 230, and further limit the degrees of freedom of the motor 200 in its own axial direction. Optionally, the stop portion 130 can be a rib structure (i.e., a stop rib).

[0048] In some embodiments of the present application, the air conditioner indoor unit further includes a motor gland 400. The motor gland 400 and the base 100 cooperate to form a mounting groove. A front boss 220 is provided at the front end of the motor 200 in the axial direction, and the front boss 220 is snap-fitted into the mounting groove. Thus, the degrees of freedom of the front end of the motor 200 in its circumferential direction can be limited by the mounting groove, and further the installation and positioning of the motor 200 can be made more stable. Among them, the front end of the motor 200 in the axial direction refers to the end of the motor 200 close to the motor shaft 230.

[0049] Optionally, as Figure 5 shown, a first semi-circular groove 140 is provided on the base 100, and a second semi-circular groove is provided on the motor cover of the motor 200. The first semi-circular groove 140 and the second semi-circular groove are snapped together to form the above-mentioned mounting groove.

[0050] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
