Detailed Implementation

[0054] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0055] As shown in Figures 1 and 2, the indoor unit of the air conditioner includes a base 1, an air guide 2, a mounting bracket 3, and a motor 4.

[0056] The base 1 can be made of plastic, metal, etc. The air guide 2 can be detachably mounted on the base 1. For example, the air guide 2 can be mounted on the front side of the base 1 by means of clips 36, screws, etc. The bottom side of the indoor air conditioner unit can be provided with an air inlet, and the upper front side of the indoor air conditioner unit can be provided with an air outlet. The air outlet can be arranged opposite to the air guide 2 in the front-back direction.

[0057] When in use, indoor air can enter the air conditioner indoor unit through the air inlet, and then be discharged from the air outlet through the air guide 2, etc. The black arrow in Figure 1 indicates the direction of airflow.

[0058] The air guide frame 2 extends along a first direction and has a recess 21. The recess 21 is located at at least one end of the air guide frame 2 in the first direction, and the recess 21 is used to avoid the drive mechanism 6 that drives the air guide plate to move. For example, as shown in Figure 3, the first direction can be a left-right direction, the air guide frame 2 as a whole can extend along the left-right direction, and both the left and right ends of the air guide frame 2 can be integrally formed with recesses 21. The recesses 21 can be steps, grooves, or other structures, and the recesses 21 can be recessed to the rear.

[0059] As shown in Figure 4, the drive mechanism 6 may include a motor, a transmission mechanism, etc. The air guide plate can be located on the front side of the air guide frame 2 and connected to the drive mechanism 6. The drive mechanism 6 can drive the air guide plate to swing, thereby facilitating the opening and closing of the air outlet or adjusting the size of the air outlet. The drive mechanism 6 can be located on the front side of the recess 21, and the motor or transmission mechanism can be fitted into the recess 21, thereby avoiding assembly interference between the drive mechanism 6 and the air guide frame 2.

[0060] The air guide frame 2 is also provided with a receiving cavity 212. For example, the material of the air guide frame 2 can be plastic, as shown in Figures 2 and 14. The air guide frame 2 can be integrally injection molded and can extend along the left and right directions. The receiving cavity 212 can be a groove-shaped structure integrally formed on the air guide frame 2, and the receiving cavity 212 can be located on the left side of the air guide frame 2.

[0061] The mounting base 3 is detachably mounted on the air guide frame 2 and located on the side of the air guide frame 2 facing the base 1, and the mounting base 3 is arranged opposite to the receiving cavity 212. For example, the material of the mounting base 3 can be plastic, etc. The mounting base 3 can be integrally injection molded, as shown in Figure 2. The mounting base 3 can be mounted on the rear side of the air guide frame 2 by means of screw fixing, snap-fit, etc., and in the front-back direction, the receiving cavity 212 can be located in front of the mounting base 3, so that the mounting base 3 can block the rear side of the receiving cavity 212.

[0062] The motor 4 is detachably mounted on the mounting base 3, with at least a portion of the motor 4 embedded within the receiving cavity 212. For example, as shown in Figure 2, the motor 4 can be a stepper motor. The motor 4 can be fixed to the front side of the mounting base 3 by means of screws, snap-fit, etc., and the entire motor 4 can be inserted into the receiving cavity 212, thereby facilitating the installation and fixing of the motor 4, achieving a proper fit between the air guide frame 2 and the motor 4, and also providing protection for the motor 4.

[0063] It should be noted that the motor 4 can also be connected to multiple air-sweeping plates 10 through a corresponding transmission mechanism. In use, the rotation of the motor 4 can drive multiple air-sweeping plates 10 to swing synchronously, thereby enabling adjustments to the airflow direction, soft wind mode (at this time, micro-holes for airflow to pass through need to be evenly distributed on each air-sweeping plate 10).

[0064] The air guide frame 2 of the indoor unit of the air conditioner in this embodiment is designed independently of the base 1, so that the air guide frame 2 can be processed independently, thereby facilitating the injection molding of the air guide frame 2 and the processing and production of the air guide frame 2. The air guide frame 2 and the mounting base 3 of the indoor unit of the air conditioner are set separately, which facilitates the processing and molding of the mounting base 3 and also improves the convenience of installation and disassembly.

[0065] Secondly, by setting a recess 21 on the air guide frame 2, the fit with the drive mechanism 6 can be improved. By setting 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 improving the overall space utilization.

[0066] In some embodiments, at least a portion of the circumferential edge of the recess 21 is provided with a folded edge 22, the folded edge 22 extending along a second direction perpendicular to the first direction, and the folded edge 22 is used to cover the gaps around the recess 21.

[0067] For example, the second direction can be the front-back direction, as shown in Figure 5. The air guide frame 2 is installed on the front side of the base 1. 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 from the front side of the air guide frame 2. The folded edge 22 can extend along the circumferential edge of the recess 21.

[0068] During assembly, the exterior parts such as the panel mounted on the front side of the air guide frame 2 can abut against the front side of the folded edge 22. The folded edge 22 can also cover the gap between the air guide frame 2 and the exterior parts. That is, from the front, only the recess 21 can be seen due to the covering of the folded edge 22, and the gap between the exterior parts and the air guide frame 2 cannot be seen, thus avoiding the black exposure and improving the overall appearance.

[0069] 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 a portion of the recess 21 is located between the first folded edge 221 and the second folded edge 222.

[0070] For example, as shown in Figure 5, the first folded edge 221 can be located on the right side of the recess 21, and the second folded edge 222 can be located on the left side of the recess 21. Both the first folded edge 221 and the second folded edge 222 can be flat and arranged opposite each other in the left-right direction. A portion of the recess 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 block the gaps on the left and right sides of the recess 21.

[0071] In some embodiments, one of the base 1 and the air guide frame 2 is provided with a first insertion hole 11, and the other is provided with a first insertion part 23. The first insertion part 23 is inserted into the first insertion hole 11 to realize the insertion assembly of the base 1 and the air guide frame 2.

[0072] For example, as shown in Figure 6, the first insertion hole 11 can be located on the top of the base 1 and at the front of the base 1. As shown in Figure 7, the first insertion part 23 can be integrally formed on the top of the air guide frame 2 and located at the rear of the air guide frame 2. During assembly, the first insertion part 23 on the air guide frame 2 can be directly inserted into the first insertion hole 11, thereby achieving pre-fixation of the air guide frame 2 and the base 1, which helps to improve assembly efficiency.

[0073] In some other embodiments, the first insertion part 23 may also be provided on the base 1, and the first insertion hole 11 may be provided on the air guide frame 2.

[0074] In some embodiments, the insertion direction of the first insertion hole 11 and the first insertion part 23 is a second direction perpendicular to the first direction, and the base 1 and the air guide plate are arranged opposite to each other in the second direction.

[0075] For example, the second direction can be the front-to-back direction, with the base 1 facing and close to the wall. In this case, since the insertion direction of the first insertion part 23 and the first insertion hole 11 is the front-to-back direction, the first insertion hole 11 on the air guide frame 2 can be directly inserted into the first insertion hole 11 along the front-to-back direction, thereby improving the convenience of assembly and disassembly.

[0076] In some embodiments, as shown in FIG6, a first insertion hole 11 is provided on the base 1, and as shown in FIG7, a first insertion part 23 is provided on the air guide frame 2. Multiple first insertion holes 11 and multiple first insertion parts 23 are provided, and the multiple first insertion holes 11 and multiple first insertion parts 23 are arranged at intervals along a first direction, wherein the first direction is the left-right direction. The multiple first insertion parts 23 are inserted and assembled one-to-one into the multiple first insertion holes 11. This ensures the structural stability of the assembly of the air guide frame 2 and the base 1 at various positions in the left-right direction.

[0077] In some embodiments, the base 1 and the air guide frame 2 are connected by 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 through which the first fastener 29 passes.

[0078] For example, as shown in Figure 6, the first column 12 can be a threaded column. The first column 12 can be located on the left side of the base 1 and can extend along the front-back direction, and the first column 12 has a threaded hole inside. As shown in Figure 7, the first fixing hole 24 can be located on the left side of the air guide frame 2 and can penetrate the air guide frame 2 along the front-back direction. The first fastener 29 can be a screw, etc. During assembly, the first fastener 29 can be directly passed through the first fixing hole 24 and threaded into the first column 12, thereby ensuring the structural stability of the assembly of the air guide frame 2 and the base 1.

[0079] 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 2 is provided with a second insertion hole 25, and the other is provided with a second insertion part 71. The second insertion part 71 is inserted into the second insertion hole 25 to realize the insertion assembly of the air guide 2 and the motor cover 7.

[0080] For example, as shown in Figure 8, the motor cover 7 can be fixed to the left side of the air guide frame 2 and located in front of the air guide frame 2. The motor cover 7 can be a semi-circular structure, and the motor cover 7 is directly opposite the recess 21 in the front-back direction, so that the motor 4 and other components used to drive the fan blades can be protected within the space enclosed by the motor cover 7 and the recess 21 of the air guide frame 2.

[0081] As shown in Figure 8, the second insertion part 71 can be integrally formed on the front side of the motor cover 7. The second insertion part 71 can be a columnar structure. As shown in Figure 9, the second insertion hole 25 can be provided on the air guide frame 2. The air guide frame 2 can be located on the front side of the motor cover 7. During assembly, the second insertion part 71 can be aligned with the second insertion hole 25 and inserted into the second insertion hole 25, thereby achieving pre-fixation of the air guide frame 2 and the motor cover 7.

[0082] In some embodiments, as shown in FIG8, the second insertion hole 25 is provided on the air guide frame 2, the second insertion part 71 is provided on the motor cover 7, the second insertion part 71 includes a plurality of plates 711, each plate 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 insertion part 71.

[0083] For example, each plate 711 can be a rectangular plate, each plate 711 can extend along the front-back direction, and the side of each plate 711 facing the center line of the insertion part can be integrally injection molded together, where the center line can be regarded as an axis extending along the front-back direction. During assembly, the outer long side of each plate 711 can abut against the wall of the second insertion hole 25, thereby enhancing the stability of the insertion assembly.

[0084] In some embodiments, the motor cover 7 and the air guide frame 2 are connected by 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 through which the second fastener 210 passes.

[0085] For example, as shown in Figure 8, 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-back direction. The second column 72 is provided with a threaded hole. As shown in Figure 10, the second fixing hole 26 can be provided on the right side of the air guide frame 2 and can penetrate the air guide frame 2 along the front-back direction.

[0086] The second fastener 210 can also be a screw, etc. During assembly, the second fastener 210 can be directly passed through the second fixing hole 26 and threaded into the second column 72, thereby ensuring the structural stability of the assembly of the air guide frame 2 and the motor cover 7.

[0087] In some embodiments, the indoor unit of the air conditioner includes a heat exchanger 5, and the heat exchanger 5 is provided with a bracket 51 at its end in a first direction. One of the bracket 51 and the air guide 2 is provided with a third insertion hole 27, and the other is provided with a third insertion part 511, which is inserted into the third insertion hole 27.

[0088] For example, as shown in Figure 11, the heat exchanger 5 can be an evaporator; in some other embodiments, the heat exchanger 5 can also be used as a condenser. A bracket 51 can be fixed to the left end of the heat exchanger 5, and a third insertion part 511 can be integrally formed on the bracket 51. The third insertion part 511 can be a protrusion with an H-shaped cross-section. As shown in Figure 12, the third insertion hole 27 can be provided on the air guide frame 2, and the third insertion hole 27 can be arranged adjacent to the left side of the air guide frame 2.

[0089] During assembly, the third insertion part 511 can be inserted into the third insertion hole 27, thereby realizing the insertion and assembly of the air guide frame 2 and the heat exchanger 5, achieving pre-positioning and pre-fixation of the two.

[0090] In some embodiments, the bracket 51 and the air guide frame 2 are connected by a third fastener 211, and the bracket 51 is provided with a third column 512 connected to the third fastener 211, and the air guide frame 2 is provided with a third fixing hole 28 for the third fastener 211 to pass through.

[0091] For example, as shown in Figure 11, the third column 512 can be integrally formed on the bracket 51, and the third column 512 extends along the front-back direction and is provided with a threaded hole. As shown in Figure 12, the third fixing hole 28 can be provided on the left side of the air guide frame 2 and penetrate through the air guide frame 2 along the front-back direction.

[0092] The third fastener 211 can also be a screw, etc. During assembly, the third fastener 211 can be directly passed through the third fixing hole 28 and threaded into the third column 512, thereby ensuring the structural stability of the assembly of the air guide frame 2 and the heat exchanger 5.

[0093] In some embodiments, as shown in FIG13, the first fastener 29, the second fastener 210, and the third fastener 211 can be arranged in a triangular shape to ensure the structural stability of the air guide frame 2.

[0094] In some embodiments, the mounting base 3 is disposed on the inner side of the air guide frame 2 facing the base 1, and the motor 4 is disposed on the outer side of the mounting base 3. It should be noted that, in actual assembly, the air guide frame 2 can be mounted on the front side of the base 1, wherein the base 1 can be positioned facing the wall, and the air outlet can be located on the front side of the air guide frame 2. The inner side of the air guide frame 2 is the side of the air guide frame 2 facing the base 1, which is also the rear side of the air guide frame 2 in Figure 14, and the outer side of the air guide frame 2 is the side of the air guide frame 2 facing the outer panel or air outlet, which is also the front side of the air guide frame 2 in Figure 14.

[0095] This allows the receiving cavity 212 of the air guide frame 2 to protrude forward, thus enabling the installation of the motor 4 to make full use of the ample space on the front side of the air guide frame 2, achieving an optimized design for space utilization.

[0096] In some embodiments, the air guide frame 2 is connected to the mounting base 3 via a fourth fastener. One of the air guide frame 2 and the mounting base 3 is provided with a plurality of fourth columns 213 connected to the fourth fastener, and the other is provided with a plurality of first holes 31 through which the fourth fastener passes.

[0097] For example, as shown in Figure 14, the fourth column 213 can be integrally formed on the air guide frame 2. The fourth column 213 can be cylindrical, and the interior of the fourth column 213 can be provided with threaded holes. As shown in Figures 15 and 16, the first hole 31 can be a circular hole, and the first hole 31 can penetrate the mounting base 3 along the thickness direction of the mounting base 3.

[0098] The fourth fastener can be a screw or the like. During assembly, the fourth fastener can be passed through the first hole 31 and threaded onto the fourth column 213, thus ensuring the structural stability of the connection between the air guide frame 2 and the mounting base 3.

[0099] In some embodiments, the fourth column 213 is provided on the air guide frame 2, and the mounting base 3 is provided with a plurality of protrusions 32. The protrusions 32 protrude into the inner side of the mounting base 3 and form a groove on the outer side of the mounting base 3 away from the base 1. The fourth column 213 is inserted into the groove, and the first hole 31 is provided on the bottom wall of the groove.

[0100] For example, as shown in Figure 14, there can be two fourth pillars 213. Both fourth pillars 213 can be integrally molded onto the air guide frame 2 by injection molding, and both fourth pillars 213 can be located on the rear side of the air guide frame 2.

[0101] As shown in Figures 15 and 16, the mounting base 3 may be provided with two bosses 32. Both bosses 32 can be integrally formed on the mounting base 3 by injection molding. The bosses 32 can be arched. Each boss 32 can protrude to the rear side of the mounting base 3 and can be restricted to the front side of the mounting base 3. Each boss 32 may be provided with a first hole 31.

[0102] During assembly, the two fourth pillars 213 on the air guide frame 2 can be inserted into the grooves of the two bosses 32 one by one, thereby enhancing the limiting constraint effect between the air guide frame 2 and the mounting base 3. Secondly, the bosses 32 can also enhance the structural strength of the mounting base 3.

[0103] In some embodiments, the mounting base 3 includes a first plate portion 33 and a second plate portion 34 that are staggered in the inward and outward directions, and both the first plate portion 33 and the second plate portion 34 are provided with bosses 32.

[0104] For example, as shown in Figure 15, both the first plate portion 33 and the second plate portion 34 can be flat, wherein the dimensions of the first plate portion 33 are larger than those of the second plate portion 34. A boss 32 can be integrally formed on both the first plate portion 33 and the second plate portion 34.

[0105] The mounting base 3 can be positioned in the front-back direction or in the back-forward direction, and the first plate portion 33 can be located in front of the second plate portion 34. During assembly, the first plate portion 33 can be arranged opposite to the rear opening of the receiving cavity 212, and the second plate portion 34 can overlap the periphery of the opening of the receiving cavity 212, thereby enhancing the limiting and restraining effect of the mounting base 3 and the air guide frame 2.

[0106] In some embodiments, one of the air guide frame 2 and the mounting base 3 is provided with a buckle 36, and the other is provided with a slot 214, wherein the buckle 36 is engaged in the slot 214.

[0107] For example, as shown in Figure 16, the buckle 36 can be integrally formed on the mounting base 3, specifically located at the outer peripheral edge of the first plate portion 33. As shown in Figure 14, the slot 214 can be provided on the air guide frame 2, and the slot 214 can be located within the receiving cavity 212.

[0108] During assembly, the mounting base 3 and the air guide frame 2 can be pre-positioned and pre-fixed by the snap-fit ​​of the buckle 36 and the slot 214. Then, the air guide frame 2 and the mounting base 3 can be connected and fixed by the fourth fastener, which can improve the assembly efficiency and enhance the structural stability of the assembly of the air guide frame 2 and the mounting base 3.

[0109] In some embodiments, the motor 4 is connected to the mounting base 3 via a fifth fastener. The mounting base 3 is provided with a plurality of fifth columns 35 connected to the fifth fastener on the outer side facing the receiving cavity 212. The motor 4 is provided with a plurality of second holes through which the fifth fastener passes.

[0110] For example, as shown in Figure 16, the fifth column 35 can be integrally formed on the front side of the mounting base 3. There can be two fifth columns 35, and each fifth column 35 can have a threaded hole. The outer periphery of the motor 4 can be provided with ear plates. There can be two ear plates, and each ear plate can have a second hole.

[0111] The fifth fastener can also be a screw, etc. During assembly, the fifth fastener can be passed through the second hole and threaded with the fifth column 35, thereby ensuring the structural stability of the assembly of the motor 4 and the mounting base 3.

[0112] In some embodiments, the outer periphery of the fifth column 35 is provided with a plurality of positioning ribs 351, the plurality of positioning ribs 351 protruding from the end of the fifth column 35 facing the receiving cavity 212, the plurality of positioning ribs 351 are arranged at intervals along the circumference of the fifth column 35, the motor 4 is provided with an ear plate, the ear plate is fitted in the space enclosed by the plurality of positioning ribs 351 to realize the assembly and positioning of the motor 4 and the mounting base 3, and a second hole is provided in the ear plate.

[0113] For example, as shown in Figure 16, each fifth column 35 may have three positioning ribs 351 on its outer periphery. The positioning ribs 351 may extend along the axial direction of the fifth column 35, and multiple positioning ribs 351 may be arranged at equal intervals along the circumference of the fifth column 35. Each positioning rib 351 may protrude from the free end of the fifth column 35, which is the end of the fifth column 35 that faces the motor 4. Thus, the three positioning ribs 351 may form a groove-shaped space at the free end of the fifth column 35.

[0114] During assembly, the ear plate on the outer periphery of the motor 4 can be first embedded in the groove-shaped space enclosed by the positioning rib 351, thereby achieving pre-positioning of the motor 4 during installation. Then, the electrode can be connected and fixed to the mounting base 3 with the help of the fifth fastener, thereby improving the overall assembly efficiency.

[0115] In some embodiments, the mounting base 3 is provided with a through hole 37, through hole 37 for the drive shaft 41 of the motor 4 to pass through the mounting base 3. For example, as shown in Figures 16 and 17, the through hole 37 can be an irregular hole structure, and the drive shaft 41 of the motor 4 installed in the receiving cavity 212 can extend from the through hole 37 to the rear side of the mounting base 3, thereby facilitating the connection and assembly of the motor 4 with the subsequent transmission shaft 8.

[0116] In some embodiments, as shown in Figures 17 to 19, the indoor unit of the air conditioner includes a drive shaft 8, the extension direction of the drive shaft 8 is perpendicular to the extension direction of the drive shaft 41, one end of the drive shaft 8 is rotatably connected to the drive shaft 41, and the other end of the drive shaft 8 is rotatably connected to the connecting rod 9 that drives the swing plate 10 to swing.

[0117] As shown in Figure 16, the mounting base 3 is provided with a limiting shaft 38, which is located inside the through hole 37. For example, the mounting base 3 may be integrally formed with an extension, which may extend into the through hole 37, and the limiting shaft 38 may be integrally formed on the extension.

[0118] The limiting shaft 38 is coaxially arranged with the drive shaft 41. The drive shaft 8 has a slot 81 on the side opposite to the drive shaft 41, and the limiting shaft 38 is rotatably fitted into the slot 81. For example, the drive shaft 8 can be located between the limiting shaft 38 and the drive shaft 41, where the drive shaft 41 can be located in front of the drive shaft 8, the limiting shaft 38 can be located in front of the drive shaft 8, the slot 81 can be a circular groove and can be located in front of the drive shaft 8, and the limiting shaft 38 can be a round shaft and can be directly inserted into the slot 81.

[0119] In use, the drive shaft 41 of the motor 4 can drive the transmission shaft 8 to swing. At this time, since the limit shaft 38 is connected to the transmission shaft 8 through the slot 81, the transmission shaft 8 can be avoided from being suspended, thus ensuring the stability of the transmission of the transmission shaft 8. This is conducive to driving each sweeping plate 10 into place through the connecting rod 9.

[0120] In some embodiments, the mounting base 3 is provided with a wire-holding groove 39, which is located at the circumferential edge of the mounting base 3 and is used to hold the wire. For example, as shown in FIG16, the wire-holding groove 39 can be provided in the first plate portion 33, and the circumferential edge of the first plate portion 33 can be provided with a slot. Two protrusions can be provided at the opening of the slot, and the two protrusions are arranged opposite to each other, making the wire-holding groove 39 a constricted structure. In use, the wires of the motor 4 can be snapped into the wire-holding groove 39, thereby facilitating the limiting and fixing of the wires.
