[0062] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0063] like Figure 1 and Figure 2 As shown, the indoor unit of the air conditioner includes a base 1, an air guide frame 2, a mounting base 3 and a motor 4.

[0064] The base 1 may be made of plastic, metal, etc., and the air guide frame 2 may be detachably mounted on the base 1. For example, the air guide frame 2 may be mounted on the front side of the base 1 by means of a buckle 36, screw fixation, etc. An air inlet may be provided on the bottom side of the air conditioner indoor unit, and an air outlet may be provided on the upper front side of the air conditioner indoor unit, and the air outlet may be arranged opposite to the air guide frame 2 in the front-to-back direction.

[0065] When in use, indoor air can enter the air conditioner through the air inlet, and then be discharged from the air outlet through the air guide frame 2. Figure 1 The black arrow in the middle indicates the direction of air flow.

[0066] The air guide frame 2 extends along the first direction and is provided with a recess 21, which is provided at least at one end of the air guide frame 2 in the first direction, and is used to avoid the driving mechanism 6 that drives the air guide plate to move. Figure 3 As shown, the first direction can be the left-right direction, the air guide frame 2 as a whole can extend along the left-right direction, and the left and right ends of the air guide frame 2 can be integrally formed with a recess 21, the recess 21 can be a step, a groove or the like, and the recess 21 can be recessed toward the rear side.

[0067] like Figure 4 As shown, the driving mechanism 6 may include a motor, a transmission mechanism, etc., and the air guide plate may be arranged at the front side of the air guide frame 2 and connected to the driving mechanism 6. The air guide plate may be driven to swing by the driving mechanism 6, thereby facilitating the opening and closing of the air outlet or adjusting the size of the air outlet. The driving mechanism 6 may be located at the front side of the recess 21, and the motor or the transmission mechanism may be fitted in the recess 21, thereby avoiding the situation where the driving mechanism 6 and the air guide frame 2 are assembled with interference.

[0068] The air guide frame 2 is further provided with a receiving cavity 212. For example, the material of the air guide frame 2 can be plastic, for example Figure 2 and Fig.14 As shown, the air guide frame 2 can be integrally injection molded and can extend along the left-right direction, the accommodating cavity 212 can be a groove-shaped structure integrally molded on the air guide frame 2, and the accommodating cavity 212 can be located on the left side of the air guide frame 2.

[0069] The mounting seat 3 is detachably mounted on the air guide frame 2 and is located on the side of the air guide frame 2 facing the base 1, and the mounting seat 3 is arranged opposite to the accommodating cavity 212. For example, the mounting seat 3 can be made of plastic, etc., and the mounting seat 3 can be processed and formed by an integral injection molding method, such as Figure 2 As shown, the mounting seat 3 can be assembled on the rear side of the air guide frame 2 by means of screw fixing, clamping, etc., and in the front-to-back direction, the accommodating cavity 212 can be located in front of the mounting seat 3, and the mounting seat 3 can have the effect of sealing the rear side of the accommodating cavity 212.

[0070] The motor 4 is detachably mounted on the mounting base 3, and at least a portion of the motor 4 is embedded in the accommodating cavity 212. Figure 2 As shown, the motor 4 can be a stepper motor, and the motor 4 can be fixed to the front side of the mounting base 3 by means of screw fixing, clamping, etc., and the motor 4 as a whole can be inserted into the above-mentioned accommodating cavity 212, thereby facilitating the installation and fixation of the motor 4, achieving the matching between the air guide frame 2 and the motor 4, and also playing a protective effect on the motor 4.

[0071] It should be noted that the motor 4 can also be connected to multiple air sweeping plates 10 through a corresponding transmission mechanism. When in use, the rotation of the motor 4 can drive the multiple air sweeping plates 10 to swing synchronously, thereby realizing the adjustment of the air outlet direction, soft wind mode (at this time, micropores for air flow to pass through need to be evenly distributed on each air sweeping plate 10).

[0072] The air guide frame 2 of the indoor unit of the air conditioner in the embodiment of the present invention is designed independently of the base 1, so that the air guide frame 2 can be independently processed, thereby facilitating the injection molding of the air guide frame 2 and facilitating the processing and production of the air guide frame 2. The air guide frame 2 and the mounting seat 3 of the indoor unit of the air conditioner are arranged separately, which facilitates the processing and production of the mounting seat 3 and improves the convenience of installation and disassembly.

[0073] Secondly, by providing a recess 21 on the air guide frame 2, the fit with the drive mechanism 6 can be improved, and by providing a receiving cavity 212 on the air guide frame 2, the fit with the motor 4 can be improved, thereby increasing the compactness of the assembly and helping to improve the overall space utilization.

[0074] In some embodiments, at least part of the circumferential edge of the recess 21 is provided with a folded edge 22 , which extends toward one side of the air guide frame 2 along a second direction, the second direction is perpendicular to the first direction, and the folded edge 22 is used to cover the gap around the recess 21 .

[0075] For example, the second direction may be a front-to-back direction, such as Figure 5 As shown, the air guide frame 2 is installed on the front side of the base 1, and the folded edge 22 can be integrally formed on the front side of the air guide frame 2. The folded edge 22 can be a plate-like structure and can protrude toward the front side of the air guide frame 2, and the folded edge 22 can extend along the circumferential edge of the recess 21.

[0076] During assembly, the appearance parts such as the panel assembled on the front side of the air guide frame 2 can be stopped against the front side of the folded edge 22, and the folded edge 22 can cover the gap between the air guide frame 2 and the appearance part. That is, viewed from the front, due to the obstruction of the folded edge 22, only the recess 21 can be seen, but the gap between the appearance part and the air guide frame 2 cannot be seen, thereby avoiding the exposure of black and improving the overall appearance.

[0077] In some embodiments, the folded edge 22 includes a first folded edge 221 and a second folded edge 222 , the first folded edge 221 and the second folded edge 222 are arranged opposite to each other in a first direction, and at least part of the recess 21 is located between the first folded edge 221 and the second folded edge 222 .

[0078] For example, Figure 5 As shown, the first folded edge 221 can be located on the right side of the recessed portion 21, and the second folded edge 222 can be located on the left side of the recessed portion 21. The first folded edge 221 and the second folded edge 222 can both be flat and arranged opposite to each other in the left-right direction, and a portion of the recessed portion 21 can be located between the first folded edge 221 and the second folded edge 222. Thus, the first folded edge 221 and the second folded edge 222 can respectively cover the gaps on the left and right sides of the recessed portion 21.

[0079] In some embodiments, one of the base 1 and the air guide frame 2 is provided with a first plug hole 11, and the other is provided with a first plug portion 23, and the first plug portion 23 is plugged into the first plug hole 11 to achieve plug-in assembly of the base 1 and the air guide frame 2.

[0080] For example, Figure 6 As shown, the first plug hole 11 can be arranged at the top of the base 1 and located at the front side of the base 1, such as Figure 7 As shown, the first plug-in portion 23 can be integrally formed at the top of the air guide frame 2 and located at the rear side of the air guide frame 2. During assembly, the first plug-in portion 23 on the air guide frame 2 can be directly plugged and assembled into the first plug-in hole 11, so that the air guide frame 2 and the base 1 can be pre-fixed, which is conducive to improving assembly efficiency.

[0081] In some other embodiments, the first plug portion 23 may also be disposed on the base 1 , and the first plug hole 11 may be disposed on the air guide frame 2 .

[0082] In some embodiments, the plugging direction of the first plugging hole 11 and the first plugging portion 23 is a second direction perpendicular to the first direction, and the base 1 and the air guide plate are arranged relatively in the second direction.

[0083] For example, the second direction can be the front-to-back direction, and the base 1 is set toward and close to the wall. At this time, since the plug-in direction of the first plug-in portion 23 and the first plug-in hole 11 is the front-to-back direction, the first plug-in hole 11 on the air guide frame 2 can be directly plugged and assembled into the first plug-in hole 11 along the direction from front to back, thereby improving the convenience of assembly and disassembly.

[0084] In some embodiments, Figure 6 As shown, the first plug hole 11 is provided on the base 1. Figure 7 As shown, the first plug part 23 is provided on the air guide frame 2, and a plurality of first plug holes 11 and first plug parts 23 are provided, and the plurality of first plug holes 11 and the plurality of first plug parts 23 are arranged at intervals along the first direction, wherein the first direction is the left-right direction, and the plurality of first plug parts 23 are plugged and assembled in the plurality of first plug holes 11 in a one-to-one correspondence. Thus, the structural stability of the assembly of the air guide frame 2 and the base 1 at various positions in the left-right direction is ensured.

[0085] In some embodiments, the base 1 and the air guide frame 2 are connected via a first fastener 29 , and the base 1 is provided with a first column 12 connected to the first fastener 29 , and the air guide frame 2 is provided with a first fixing hole 24 for the first fastener 29 to pass through.

[0086] For example, Figure 6 As shown, the first column 12 may be a threaded column, and the first column 12 may be disposed on the left side of the base 1 and may extend along the front-to-back direction, and a threaded hole may be disposed in the first column 12. Figure 7 As shown, the first fixing hole 24 can be provided on the left side of the air guide frame 2 and can penetrate the air guide frame 2 along the front-to-back direction. The first fastener 29 can be a screw, etc., and during assembly, the first fastener 29 can be directly passed through the first fixing hole 24 and threadedly assembled in the first column 12, thereby ensuring the structural stability of the assembly of the air guide frame 2 and the base 1.

[0087] In some embodiments, the indoor unit of the air conditioner includes a motor cover 7, which is arranged opposite to the recess 21 in a second direction orthogonal to the first direction. One of the motor cover 7 and the air guide frame 2 is provided with a second plug-in hole 25, and the other is provided with a second plug-in portion 71. The second plug-in portion 71 is plugged into the second plug-in hole 25 to realize the plug-in assembly of the air guide frame 2 and the motor cover 7.

[0088] For example, Figure 8 As shown, the motor cover 7 can be fixed on the left side of the wind guide frame 2 and located at the front side of the wind guide frame 2. The motor cover 7 can be a semicircular structure, and the motor cover 7 is directly opposite to the recess 21 in the front-to-back direction, so that the motor 4 used to drive the fan blades to rotate can be protected in the space surrounded by the motor cover 7 and the recess 21 of the wind guide frame 2.

[0089] like Figure 8 As shown, the second plug-in portion 71 can be integrally formed on the front side of the motor cover 7, and the second plug-in portion 71 can be a columnar structure, such as Fig. 9 As shown, the second plug hole 25 can be provided on the air guide frame 2. The air guide frame 2 can be located in front of the motor cover 7. During assembly, the second plug part 71 can be aligned with the second plug hole 25 and inserted into the second plug hole 25, so that the air guide frame 2 and the motor cover 7 can be pre-fixed.

[0090] In some embodiments, Figure 8 As shown, the second plug-in hole 25 is provided on the air guide frame 2, the second plug-in portion 71 is provided on the motor cover 7, the second plug-in portion 71 includes a plurality of plates 711, each of the plates 711 extends along the second direction, and the inner edges of the plurality of plates 711 are connected, and the plurality of plates 711 are arranged at intervals along the circumference of the second plug-in portion 71.

[0091] For example, each plate body 711 can be a rectangular plate, each plate body 711 can extend in the front-to-back direction, and each plate body 711 can be integrally connected by injection molding on one side facing the center line of the plug-in portion, wherein the center line can be regarded as an axis extending in the front-to-back direction. During assembly, the outer long side of each plate body 711 can abut against the hole wall of the second plug-in hole 25, thereby enhancing the stability of the plug-in assembly.

[0092] In some embodiments, the motor cover 7 and the air guide frame 2 are connected via a second fastener 210 , and the motor cover 7 is provided with a second column 72 connected to the second fastener 210 , and the air guide frame 2 is provided with a second fixing hole 26 for the second fastener 210 to pass through.

[0093] For example, Figure 8 As shown, the second column 72 can be integrally formed on the front side of the motor cover 7, the second column 72 can be cylindrical and can extend along the front-to-back direction, and a threaded hole is provided in the second column 72. Fig.10 As shown, the second fixing hole 26 may be provided on the right side of the air guide frame 2 and may penetrate the air guide frame 2 along the front-to-back direction.

[0094] The second fastener 210 may also be a screw, etc. During assembly, the second fastener 210 is directly passed through the second fixing hole 26 and threadedly assembled in the second column 72, thereby ensuring the structural stability of the assembly of the air guide frame 2 and the motor cover 7.

A bracket 51 can be fixed to the left end of the heat exchanger 5. The bracket 51 can be integrally formed with a third plug-in portion 511. The third plug-in portion 511 can be a protrusion with an H-shaped cross section. Fig.12 As shown, the third plugging hole 27 can be provided on the air guide frame 2 , and the third plugging hole 27 can be arranged adjacent to the left side of the air guide frame 2 .

[0097] During assembly, the third plug-in portion 511 can be plugged and assembled into the third plug-in hole 27, so that the plug-in assembly and fixation of the air guide frame 2 and the heat exchanger 5 can be achieved, and the pre-positioning and pre-fixation of the two can be achieved.
