Detailed implementation mode

[0062] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0063] The air outlet frame assembly 200 according to an embodiment of the present invention will be described below with reference to the drawings. The air outlet frame assembly 200 can be used in an air treatment device. For example, the air outlet frame assembly 200 can be used in an air conditioner.

[0064] As Figures 7 - 12 shown, the air outlet frame assembly 200 according to the first aspect embodiment of the present invention includes: an air outlet frame 20, a protective member 22, an air guiding component 40, and a drive mechanism 30.

[0065] At least one air outlet channel 201 is formed on the air outlet frame 20. The air outlet channel 201 can be one, or can be multiple. For example, the air outlet channels 201 can be two arranged left and right. A rotating hole 202 can be formed on the inner wall of the air outlet channel 201, and the rotating hole 202 penetrates through the wall of the air outlet channel 201 along the wall thickness direction of the air outlet channel 201. The air guiding component 40 is rotatably arranged in the air outlet channel 201, and a part of the air guiding component 40 extends into the rotating hole 202 and is rotatable relative to the rotating hole 202. The driving mechanism 30 is used to drive the air guiding component 40 to rotate. The driving mechanism 30 is connected to the air guiding component 40 to drive the air guiding component 40 to rotate. The driving mechanism 30 is arranged outside the air outlet channel 201. For example, the driving mechanism 30 is arranged on one side of the air outlet channel 201, and the driving mechanism 30 can be installed and fixed on the air outlet frame 20 through fasteners such as screws.

[0066] It should be noted that the "multiple" mentioned in the present invention means two or more.

[0067] The outer port end of the air outlet channel 201 is the air outlet end. After the air flow passes through the air outlet channel 201 and is guided by the air guiding component 40, it is finally blown out of the air outlet end of the air outlet channel 201 to the room. By rotating the air guiding component 40, the air outlet end of the air outlet channel 201 can be opened and closed, and by rotating the air guiding component 40 to different angular positions, the air flow can be made to flow in different directions. Herein, the side wall of the air outlet channel 201 is relative to the rotation axis of the air guiding component 40 installed in the air outlet channel 201. For example, when the rotation axis of the air guiding component 40 extends in the up and down direction, the rotating hole 202 can be formed on the bottom wall of the air outlet channel 201, and the lower end of the air guiding component 40 extends into the rotating hole 202.

[0068] The protective member 22 is arranged on the air outlet frame 20. The protective member 22 can be located outside the air outlet channel 201. For example, the protective member 22 can be located on the side of the rotating hole 202 adjacent to the driving mechanism 30. The protective member 22 has a through hole 2211, and the through hole 2211 extends along the axial direction of the air guiding component 40. The through hole 2211 can be correspondingly arranged with the rotating hole 202 on the air outlet frame 20 in the axial direction of the rotating hole 202, and the through hole 2211 is communicated with the rotating hole 202. The through hole 2211 and the rotating hole 202 can be coaxially arranged.

[0069] An anti-electricity shaft 32 can be sleeved on the driving shaft 31 of the driving mechanism 30. For example, the driving mechanism 30 can be a motor, and the driving shaft 31 can be a motor shaft. By sleeving the anti-electricity shaft 32 on the driving shaft 31 of the driving mechanism 30, the potential safety hazard problem caused by the exposure of the driving shaft 31 can be avoided. A part of the anti-electricity shaft 32 can pass through the through hole 2211 and be detachably connected to the air guiding component 40, thereby facilitating the disassembly, assembly and maintenance of the air guiding component 40.

[0070] For example, inFigure 12 In the example, the rotation axis of the air guiding component 40 extends in the up and down direction. The rotation hole 202 is formed in the bottom wall of the air outlet channel 201. The protection component 22 is arranged on the bottom surface of the air outlet frame 20 and adjacent to the rotation hole 202. The through hole 2211 of the protection component 22 is opposite to and communicated with the rotation hole 202. The driving mechanism 30 is installed and fixed on the bottom surface of the air outlet frame 20. An anti-electricity shaft 32 is sleeved on the driving shaft 31 of the driving mechanism 30 and the anti-electricity shaft 32 is fixed relative to the driving shaft 31. For example, the anti-electricity shaft 32 can be in interference fit with the driving shaft 31. The anti-electricity shaft 32 passes through the through hole 2211 and the upper end of the anti-electricity shaft 32 extends upward into the rotation hole 202 and is detachably connected to the air guiding component 40.

[0071] Wherein, the maximum projection of the cross-section of the anti-electricity shaft 32 on the reference plane can be the first projection, and the minimum projection of the cross-section of the through hole 2211 on the reference plane can be the second projection. A part of the first projection is located outside the second projection. The reference plane is perpendicular to the axial direction of the driving shaft 31. The cross-section of the anti-electricity shaft 32 and the cross-section of the through hole 2211 are both perpendicular to the axial direction of the driving shaft 31. Among all the projections of the cross-sections of the anti-electricity shaft 32 on the reference plane, the projection with the largest area is the first projection, and among all the projections of the cross-sections of the through hole 2211 on the reference plane, the projection with the smallest area is the second projection. By making a part of the first projection located outside the second projection, in the process of disassembling the air guiding component 40, if the anti-electricity shaft 32 moves axially towards the direction adjacent to the air guiding component 40, due to the blocking effect of the protection component 22 on the anti-electricity shaft 32, it can be avoided that the anti-electricity shaft 32 escapes through the through hole 2211 and the rotation hole 202, thereby avoiding or significantly reducing the probability of the anti-electricity shaft 32 detaching from the driving shaft 31, improving safety, and better meeting the safety regulations requirements.

[0072] For the air outlet frame assembly 200 according to the embodiment of the present invention, by arranging the protection component 22 at a position on the air outlet frame 20 adjacent to the rotation hole 202, such that a part of the anti-electricity shaft 32 passes through the through hole 2211 of the protection component 22 and is detachably connected to the air guiding component 40, and by making a part of the maximum projection of the cross-section of the anti-electricity shaft 32 on the reference plane located outside the minimum projection of the cross-section of the through hole 2211 on the reference plane, it can play a role in limiting the anti-electricity shaft 32. In the process of disassembling the air guiding component 40, it can avoid or significantly reduce the probability of the anti-electricity shaft 32 detaching from the driving shaft 31, improve safety, and better meet the safety regulations requirements.

[0073] According to some embodiments of the present invention, the second projection may be located within the first projection, for example, the second projection and the first projection may both be circular, and the diameter of the second projection may be smaller than the diameter of the first projection. Thus, during the disassembly of the air guide component 40, the protective member 22 may play a better blocking role for the anti-electricity shaft 32, and may better prevent the anti-electricity shaft 32 from escaping through the perforation 2211 and the rotation hole 202, thereby further preventing or reducing the probability of the anti-electricity shaft 32 escaping from the drive shaft 31, further improving safety, and better complying with safety regulations.

[0074] According to some embodiments of the present invention, referring to Figures 7 - 12 , Figure 16 and Figure 20 , the rotation axis of the air guide component 40 can extend in the up-down direction, and the driving mechanism 30 can be located below the air guide component 40. The rotating hole 202 can be formed on the bottom wall of the air outlet channel 201, and a water retaining protrusion 203 is formed on the bottom wall of the air outlet channel 201. The water retaining protrusion 203 can be located on the outer peripheral side of the rotating hole 202 and surround the rotating hole 202. The water retaining protrusion 203 can be annular. By arranging the water retaining protrusion 203 on the outer peripheral side of the rotating hole 202, when the condensed water generated in the air guide component 40 or the air outlet channel 201 flows downward to the bottom wall of the air outlet channel 201, the water retaining protrusion 203 can prevent the condensed water from entering the rotating hole 202 and flowing along the rotating hole 202 and the perforation 2211 to the driving mechanism 30, thereby reducing the failure risk of the driving mechanism 30 and improving the stability and reliability of the operation of the driving mechanism 30.

[0075] According to some optional embodiments of the present invention, referring to Figures 7 - 12 , Figure 16 and Figure 20 A portion of the bottom wall of the air outlet channel 201 protrudes toward the direction adjacent to the air outlet channel 201 to form a water retaining protrusion 203, that is, a portion of the bottom wall of the air outlet channel 201 protrudes upward to form the water retaining protrusion 203, which facilitates the formation of the water retaining protrusion 203. The inner peripheral side of the water retaining protrusion 203 defines the rotating hole 202, and the inner peripheral wall of the water retaining protrusion 203 constitutes the inner peripheral wall of the rotating hole 202. In this way, the condensed water is blocked from entering the rotating hole 202 by the water retaining protrusion 203, and because the height position of the rotating hole 202 is relatively high, the condensed water can be better prevented from entering the rotating hole 202.

[0076] According to some embodiments of the present invention, referring to Figures 11 - 20 as well as Figure 24, a bushing 21 is provided between the air guiding member 40 and the inner peripheral wall of the rotating hole 202. The bushing 21 is connected to the air outlet frame 20. The bushing 21 can be snap-fitted to the air outlet frame 20 and is fixed relative to the air outlet frame 20. A part of the air guiding member 40 extends into the bushing 21 and is rotatable relative to the bushing 21. The bushing 21 can be a polyoxymethylene plastic part, so that the bushing 21 can have a good lubricating effect and reduce the frictional wear generated between the air guiding member 40 and the air outlet frame 20 when the air guiding member 40 rotates. The protective member 22 includes a connected protective ring 221 and connecting ribs 222. The connecting ribs 222 can be connected to the outer peripheral wall of the protective ring 221. The connecting ribs 222 can be connected to the air outlet frame 20, and the connection and fixation of the protective member 22 and the air outlet frame 20 are realized through the connecting ribs 222. The above-mentioned through hole 2211 is defined inside the protective ring 221. The protective ring 221 can be located on the side of the bushing 21 adjacent to the driving mechanism 30. There is a gap between the protective ring 221 and the bushing 21 in the axial direction, so as to avoid interference between the bushing 21 and the protective ring 221 during the installation process of the bushing 21.

[0077] According to some alternative embodiments of the present invention, referring to Figures 11 - 20 and Figure 24 , one end of the connecting rib 222 can be connected to the outer peripheral wall of the protective ring 221, the other end of the connecting rib 222 can extend in the direction adjacent to the bushing 21 and the other end of the connecting rib 222 can be connected to the air outlet frame 20. An avoidance notch 213 for avoiding the connecting rib 222 can be formed on the bushing 21. The upper end of the connecting rib 222 can be received in the avoidance notch 213 and connected to the air outlet frame 20. Thus, the structure is compact and interference between the protective member 22 and the bushing 21 can be avoided.

[0078] According to some specific embodiments of the present invention, referring to Figures 11 - 20 and Figure 24 , there are multiple connecting ribs 222. The multiple connecting ribs 222 can be arranged at intervals along the circumferential direction of the protective ring 221. The number of the avoidance notches 213 can be the same as the number of the connecting ribs 222 and they are in one-to-one correspondence. Each avoidance notch 213 avoids the corresponding connecting rib 222. A part of each connecting rib 222 is received in the corresponding avoidance notch 213. The part of the bushing 21 located between adjacent avoidance notches 213 can be located in the space defined between adjacent connecting ribs 222. By providing the multiple connecting ribs 222, the connection strength between the protective member 22 and the air outlet frame 20 can be improved and the structure can be made more compact.

[0079] According to some alternative embodiments of the present invention, referring to Figures 11 - 20 and Figure 24, the bushing 21 includes a bushing body 210, a first limiting protrusion 211, and a second limiting protrusion 212. The first limiting protrusion 211 and the second limiting protrusion 212 are both formed on the outer peripheral wall of the bushing body 210. The first limiting protrusion 211 and the second limiting protrusion 212 are arranged at intervals along the axial direction of the bushing body 210. The above-mentioned avoidance notch 213 may be formed on the bushing body 210 and the avoidance notch 213 may penetrate through the second limiting protrusion 212. When the bushing 21 is installed at the rotating hole 202, the inner peripheral wall of the rotating hole 202 is received in the fitting groove 214 defined by the first limiting protrusion 211, the second limiting protrusion 212, and the outer peripheral wall of the bushing body 210. The first limiting protrusion 211 is located on one axial side of the rotating hole 202, and the second limiting protrusion 212 is located on the other axial side of the rotating hole 202. The first limiting protrusion 211 and the second limiting protrusion 212 are respectively in contact with the two axial end faces of the rotating hole 202, so that the bushing 21 can be reliably installed at the rotating hole 202, and the installation of the bushing 21 is convenient.

[0080] Among them, a first rib 204 is formed on the inner wall of the air outlet channel 201 adjacent to the driving mechanism 30. The first rib 204 is located on the outer peripheral side of the bushing 21, and the first rib 204 surrounds the bushing 21. The first rib 204 may be annular. Specifically, the first rib 204 is located on the outer peripheral side of the first limiting protrusion 211 and surrounds the first limiting protrusion 211. The first limiting protrusion 211 may be annular. The first rib 204 simultaneously surrounds the rotating hole 202 and the first rib 204 is spaced from the rotating hole 202 by a certain distance in the radial direction. The first limiting protrusion 211 is received in the space defined by the first rib 204 and the outer peripheral edge of the rotating hole 202. By providing the above-mentioned first rib 204, and through the first rib 204 surrounding the bushing 21 and cooperating with the bushing 21, when the condensed water generated in the air guiding component 40 or the air outlet channel 201 flows downward to the bottom wall of the air outlet channel 201, the first rib 204 can block the condensed water from entering the bushing 21 and flowing along the through hole 2211 to the driving mechanism 30. At the same time, it can also reduce the cold air in the air outlet channel 201 from blowing onto the driving mechanism 30 to generate condensed water, reduce the failure risk of the driving mechanism 30, and improve the stability and reliability of the operation of the driving mechanism 30.

[0081] According to some alternative embodiments of the present invention, with reference to Figure 12 , a second rib 523 is formed on one side of the air guiding component 40 adjacent to the bushing 21. The second rib 523 abuts against the bushing 21 in the axial direction. Thus, the contact area between the air guiding component 40 and the bushing 21 in the axial direction can be reduced, the friction between the air guiding component 40 and the bushing 21 when the air guiding component 40 rotates can be reduced, and at the same time, the gap between the air guiding component 40 and the bushing 21 in the axial direction can be reduced, and the cold air in the air outlet channel 201 blowing onto the driving mechanism 30 to generate condensed water can be minimized, improving the stability and reliability of the operation of the driving mechanism 30.

[0082] In some specific embodiments of the present invention, with reference to Figures 11 - 20 and Figure 24 , the rotation axis of the air guiding member 40 extends in the up and down direction. A part of the bottom wall of the air outlet passage 201 protrudes upward to form a water retaining protrusion 203. The water retaining protrusion 203 is annular. The inner peripheral side of the water retaining protrusion 203 defines a rotation hole 202. The upper surface of the water retaining protrusion 203 is formed with a first rib 204. The first rib 204 is annular and surrounds the circumference of the rotation hole 202. The first rib 204 and the circumference of the rotation hole 202 are spaced apart in the radial direction. A bushing 21 is provided between the air guiding member 40 and the inner peripheral wall of the rotation hole 202. The bottom surface of the air guiding member 40 is provided with a second rib 523. The second rib 523 abuts against the bushing 21 in the axial direction. The protective member 22 includes a connected protective ring 221 and connecting ribs 222. The above-mentioned through hole 2211 is defined inside the protective ring 221. The protective ring 221 is located on the side of the bushing 21 adjacent to the driving mechanism 30. There is a gap between the protective ring 221 and the bushing 21 in the axial direction, which can avoid interference between the bushing 21 and the protective ring 221 during the installation process. There are multiple connecting ribs 222. The multiple connecting ribs 222 can be arranged at intervals along the circumference of the protective ring 221. The lower end of each connecting rib 222 is connected to the protective ring 221. The upper end of each connecting rib 222 extends upward and is connected to the air outlet frame 20.

[0083] The bushing 21 includes a bushing body 210, a first limiting protrusion 211 and a second limiting protrusion 212. The first limiting protrusion 211 and the second limiting protrusion 212 are both formed on the outer peripheral wall of the bushing body 210. The first limiting protrusion 211 and the second limiting protrusion 212 are arranged at intervals along the axial direction of the bushing body 210, and the first limiting protrusion 211 is located above the second limiting protrusion 212. A plurality of avoiding notches 213 are formed on the bushing body 210. The plurality of avoiding notches 213 are arranged at intervals along the circumference of the bushing body 210. Each avoiding notch 213 penetrates the bushing body 210 and the second limiting protrusion 212 along the wall thickness direction of the bushing body 210, and each avoiding notch 213 penetrates the lower end surface of the bushing body 210. The number of the avoiding notches 213 is the same as and corresponds to the number of the connecting ribs 222 one by one.

[0084] When the bushing 21 is installed at the rotating hole 202, the inner peripheral wall of the rotating hole 202 is received in the fitting groove 214 defined by the first limiting protrusion 211, the second limiting protrusion 212 and the outer peripheral wall of the bushing body 210. The first limiting protrusion 211 is located on the upper side of the rotating hole 202 in the axial direction, and the second limiting protrusion 212 is located on the lower side of the rotating hole 202 in the axial direction. The first limiting protrusion 211 and the second limiting protrusion 212 are respectively in contact with the two axial end faces of the rotating hole 202, so that the bushing 21 can be reliably installed at the rotating hole 202, and the installation of the bushing 21 is convenient. The second rib 523 on the bottom surface of the air guiding member 40 abuts against the upper surface of the first limiting protrusion 211 of the bushing 21, reducing the cold air in the air outlet channel 201 from blowing towards the driving mechanism 30, and reducing the contact area between the air guiding member 40 and the bushing 21, and reducing the frictional wear between the air guiding member 40 and the bushing 21 when the air guiding member 40 rotates. Each avoiding notch 213 avoids the corresponding connecting rib 222, and a part of each connecting rib 222 is received in the corresponding avoiding notch 213. The part of the bushing 21 located between the adjacent avoiding notches 213 can be located in the space defined between the adjacent connecting ribs 222, which can improve the connection strength between the protective member 22 and the air outlet frame 20, and make the structure more compact.

[0085] According to some embodiments of the present invention, the protective member 22 can be integrally formed with the air outlet frame 20. For example, the protective member 22 and the air outlet frame 20 can be integrally injection molded. Thus, the processing and forming process of the protective member 22 can be reduced, the assembly process of the protective member 22 and the air outlet frame 20 can be omitted, the production efficiency can be improved, and the connection strength between the protective member 22 and the air outlet frame 20 can be relatively high.

[0086] According to some embodiments of the present invention, the protective member 22 and the air outlet frame 20 can both be independently formed parts. After the protective member 22 and the air outlet frame 20 are respectively independently formed, they are assembled. For example, the protective member 22 and the air outlet frame 20 can be detachably connected, which can reduce the difficulty of the forming process, and reduce the complexity and cost of the mold.

[0087] According to some embodiments of the present invention, referring to Figure 12 , the axial end face of the protective member 22 adjacent to the driving mechanism 30 is the first limiting face 2212, and the anti-electricity shaft 32 has a second limiting face 3221 axially opposite to the first limiting face 2212. In the process of disassembling and washing the air guiding member 40, if the anti-electricity shaft 32 moves axially, through the limiting effect brought by the mutual cooperation of the first limiting face 2212 of the protective member 22 and the second limiting face 3221 of the anti-electricity shaft 32, it can better prevent the anti-electricity shaft 32 from disengaging from the through hole 2211 and the rotating hole 202, so as to avoid or significantly reduce the probability of the anti-electricity shaft 32 disengaging from the driving shaft 31, improve safety, and better meet the safety regulations requirements.

[0088] According to some alternative embodiments of the present invention, with reference to Figure 9 and Figure 12 , the air guiding member 40 includes an air guiding member body 401 and a connecting member 7. The connecting member 7 is movably disposed on the air guiding member body 401 between a first position and a second position. For example, the connecting member 7 is movably disposed on the air guiding member body 401 along the axial direction of the air guiding member 40. When the connecting member 7 is in the first position, the connecting member 7 extends into the rotating hole 202 and is connected to the anti-electricity shaft 32; when the connecting member 7 is in the second position, the connecting member 7 is separated from the anti-electricity shaft 32. By moving the connecting member 7 between the first position and the second position, the connection and separation between the connecting member 7 and the anti-electricity shaft 32 can be conveniently achieved, so that the connection and separation between the air guiding member 40 and the driving mechanism 30 can be facilitated, and the disassembly and assembly of the air guiding member 40 are more convenient. When it is necessary to disassemble the air guiding member 40, the connecting member 7 is moved from the first position to the second position, so that the connecting member 7 is separated from the anti-electricity shaft 32, and the separation between the air guiding member 40 and the driving mechanism 30 is realized, thereby facilitating the removal of the air guiding member 40; when it is necessary to install the air guiding member 40, the connecting member 7 is moved from the second position to the first position, so that the connecting member 7 extends into the rotating hole 202 and is connected to the anti-electricity shaft 32, and at this time the connecting member 7 is fixed relative to the air guiding member body 401, and the connection between the air guiding member 40 and the driving mechanism 30 is realized, thereby facilitating the installation of the air guiding member 40.

[0089] For example, taking the rotation axis of the air guiding member 40 extending in the up-down direction as an example, the connecting member 7 is movable between the first position and the second position along the up-down direction. When it is necessary to disassemble the air guiding member 40, the connecting member 7 is pulled upward, so that the connecting member 7 is moved from the first position to the second position, so that the connecting member 7 is separated from the anti-electricity shaft 32, and the separation between the air guiding member 40 and the anti-electricity shaft 32 is realized, thereby facilitating the removal of the air guiding member 40; when it is necessary to install the air guiding member 40, the connecting member 7 is pressed downward, so that the connecting member 7 is moved from the second position to the first position, so that the connecting member 7 extends into the rotating hole 202 and is connected to the anti-electricity shaft 32, and at this time the connecting member 7 is fixed relative to the air guiding member body 401, and the connection between the air guiding member 40 and the anti-electricity shaft 32 is realized, thereby facilitating the installation of the air guiding member 40.

[0090] Among them, with reference to Figure 12, the axial distance between the first limiting surface 2212 and the second limiting surface 3221 is d, the stroke of the connecting member 7 is L1, the stroke of the connecting member 7 is the axial distance between the first position and the second position, and d is less than L1, that is, the axial distance d between the first limiting surface 2212 and the second limiting surface 3221 is less than the stroke L1 of the connecting member 7. If the axial distance between the first limiting surface 2212 and the second limiting surface 3221 is too large, when it is necessary to disassemble the air guiding component 40, during the process of moving the connecting member 7 from the first position to the second position, if the anti-electricity shaft 32 follows the connecting member 7 to move (for example, the anti-electricity shaft 32 follows the connecting member 7 to move upward), it will cause the connecting member 7 to be unable to disconnect from the anti-electricity shaft 32. The consequence is that the air guiding component 40 is stuck and cannot be disassembled. By making the axial distance d between the first limiting surface 2212 and the second limiting surface 3221 less than the stroke L1 of the connecting member 7, it is better ensured that the air guiding component 40 can be removed.

[0091] In some alternative embodiments of the present invention, referring to Figure 12 , the axial mating length between the air guiding component 40 and the anti-electricity shaft 32 is L2, and the sum of d and L2 is less than L1, that is, d + L2 < L1. With this setting, when it is necessary to disassemble the air guiding component 40, during the process of moving the connecting member 7 from the first position to the second position, if the anti-electricity shaft 32 follows the connecting member 7 to move (for example, the anti-electricity shaft 32 follows the connecting member 7 to move upward), when the anti-electricity shaft 32 moves to contact the first limiting surface 2212 and the second limiting surface 3221, the anti-electricity shaft 32 cannot continue to move with the connecting member 7, while the connecting member 7 can continue to move until the connecting member 7 disconnects from the anti-electricity shaft 32. In this way, it can not only prevent the anti-electricity shaft 32 from moving into the air outlet passage 201 through the through hole 2211 and the rotating hole 202 following the connecting member 7, reducing the risk of the anti-electricity shaft 32 coming out, but also further avoid the situation of being stuck and unable to be disassembled during the process of disassembling the air guiding component 40, ensuring that the air guiding component 40 can be disassembled.

[0092] According to some alternative embodiments of the present invention, referring to Figure 12, the axial distance between the first limiting surface 2212 and the second limiting surface 3221 is d, the axial mating length of the anti-electricity shaft 32 and the driving shaft 31 is L3, and d is less than L3. Through this setting, when the air guiding component 40 needs to be disassembled, during the process of moving the connecting piece 7 from the first position to the second position, if the anti-electricity shaft 32 follows the connecting piece 7 to move (for example, the anti-electricity shaft 32 moves upward following the connecting piece 7), when the anti-electricity shaft 32 moves to contact the first limiting surface 2212 and the second limiting surface 3221, the anti-electricity shaft 32 cannot continue to move with the connecting piece 7. In this way, it can not only prevent the anti-electricity shaft 32 from moving into the air outlet channel 201 following the connecting piece 7 through the through hole 2211 and the rotating hole 202, but also prevent the anti-electricity shaft 32 from detaching from the driving shaft 31 during the movement with the connecting piece 7. Furthermore, it can further reduce the probability of the anti-electricity shaft 32 detaching from the driving shaft 31 during the disassembly of the air guiding component 40, further improve safety, and better meet the safety regulations requirements.

[0093] Next, refer to Figures 7 - 24 to describe the air outlet frame assembly 200 according to some specific embodiments of the present invention. In this embodiment, the air outlet frame assembly 200 is used for an air conditioner, and the air conditioner has a normal air supply mode and a draft-free air supply mode.

[0094] The air outlet frame assembly 200 includes an air outlet frame 20, a protective member 22, a bushing 21, an air guiding component 40, and a driving mechanism 30. Two air outlet channels 201 are formed on the air outlet frame 20, and the two air outlet channels 201 are arranged in the left-right direction and both extend in the up-down direction. A rotatable air guiding component 40 is provided in each air outlet channel 201, the rotation axis of the air guiding component 40 extends in the up-down direction, a rotating hole 202 is formed on the bottom wall of each air outlet channel 201, the protective member 22 is arranged on the bottom surface of the air outlet frame 20 and adjacent to the rotating hole 202, and the through hole 2211 of the protective member 22 is opposite to and communicated with the rotating hole 202. The driving mechanism 30 is installed and fixed on the bottom surface of the air outlet frame 20, and an anti-electricity shaft 32 is sleeved on the driving shaft 31 of the driving mechanism 30 and the anti-electricity shaft 32 is fixed relative to the driving shaft 31.

[0095] The air guiding component 40 includes an air guiding component body 401 and a connecting piece 7. The air guiding component body 401 includes an outer air guiding plate 4 and an inner air guiding assembly. The outer air guiding plate 4 is connected to the outside of the inner air guiding assembly. A wind-dispersing structure 41 through which air can pass may be formed on the outer air guiding plate 4, and the wind-dispersing structure 41 may include a plurality of wind-dispersing holes. The inner air guiding assembly includes an inner air guiding plate 5, a guide vane assembly 61, and a louver mechanism 62. The inner air guiding plate 5 may include an inner air guiding plate body 51 and an inner extension portion 52. The inner extension portion 52 is connected to the lower side of the inner air guiding plate body 51. The inner extension portion 52 is located on the side of the inner air guiding plate body 51 away from the outer air guiding plate 4. The inner extension portion 52 and the inner air guiding plate body 51 are disposed substantially perpendicular to each other, and the inner air guiding plate body 51 may be connected to the outer air guiding plate 4.

[0096] The guide vane assembly 61 and the louver mechanism 62 are both provided on the inner air guide plate body 51. The guide vane assembly 61 may include stationary vanes 612 and rotatable moving vanes 611. The moving vanes 611 are multiple and arranged at intervals in the up and down direction, and the moving vanes 611 are located between the outer air guide plate 4 and the inner air guide plate body 51. Air passing holes 513 are formed at positions on the inner air guide plate body 51 opposite to the moving vanes 611. The number of the air passing holes 513 is the same as that of the moving vanes 611 and they correspond one by one. Each air passing hole 513 is provided with a stationary vane 612 and the stationary vane 612 is fixed relative to the inner air guide plate 5. The louver mechanism 62 is provided on the side of the inner air guide plate body 51 away from the outer air guide plate 4. The louver mechanism 62 includes a connecting rod 621 and multiple louvers 622. The connecting rod 621 extends in the up and down direction and is movable in the up and down direction. The multiple louvers 622 are arranged at intervals in the up and down direction. Each louver 622 is rotatably connected to the connecting rod 621 and the inner air guide plate body 51. The number of the louvers 622 is the same as that of the air passing holes 513 and they correspond one by one. Specifically, each stationary vane 612 provided in each air passing hole 513 has a stationary vane hub, each moving vane 611 has a moving vane rotating shaft, each louver 622 has a louver rotating shaft. The louver rotating shaft of each louver 622 is connected to and relatively fixed to the moving vane rotating shaft of the corresponding moving vane 611. The moving vane rotating shaft of each moving vane 611 is rotatably fitted in the corresponding stationary vane hub. Each moving vane 611 is connected to the louver rotating shaft. When the louver rotating shaft rotates, it can synchronously drive the corresponding moving vane 611 to rotate.

[0097] When this air guide component 40 is used in an air conditioner, when the air guide component 40 rotates to the position of closing the air outlet passage 201, the air conditioner can implement the above-mentioned draft-free mode; when the air guide component 40 rotates to the position of opening the air outlet passage 201, the air conditioner can implement the normal air outlet mode. In the draft-free mode, the air flow can first pass through the guiding action of the louver mechanism 62 and flow to the air passing holes 513 on the inner air guide plate body 51. The air flow sequentially passes through the stationary vanes 612 and the multiple moving vanes 611. The multiple rotating moving vanes 611 can make the air flow form a swirl and blow towards the outer air guide plate 4, and finally blow towards the room through the air dispersion structure 41 on the outer air guide plate 4. In this way, after the air flow passes through this air guide assembly, the blown air flow can be made softer and closer to natural wind, so that the draft-free mode can be implemented. In the normal air outlet mode, the air flow can flow towards the room through the guiding action of the louver mechanism 62.

[0098] Among them, the louver driving mechanism for driving the movement of the louver mechanism 62 can be arranged above the louver mechanism 62. The louver driving mechanism can include a louver driving motor, a driving gear, and a driving rack. The driving gear is fixedly connected to the motor shaft of the louver driving motor. The driving gear meshes with the driving rack, and the driving rack is connected to the connecting rod 621. When the louver driving motor works, it drives the driving gear to rotate. Through the meshing of the driving gear and the driving rack, the driving rack can be driven to move in the up and down direction, thereby driving the connecting rod 621 to move in the up and down direction, and further driving the plurality of louvers 622 to swing. The plurality of louvers 622 can be swung to a set direction, or the plurality of louvers 622 can be swung back and forth.

[0099] The connecting member 7 is movably arranged up and down between a first position and a second position on the inner air guide plate 5. When the connecting member 7 is in the first position, the connecting member 7 extends into the rotating hole 202 and is connected to the anti-electricity shaft 32. When the connecting member 7 is in the second position, the connecting member 7 is separated from the anti-electricity shaft 32. By moving the connecting member 7 between the first position and the second position, the connection and separation of the connecting member 7 and the driving mechanism 30 can be conveniently realized, so that the connection and separation of the air guide component 40 and the driving mechanism 30 can be facilitated, and the disassembly and assembly of the air guide component 40 are more convenient.

[0100] The connecting member 7 includes a connecting portion 71 and a positioning portion 72. The connecting portion 71 includes a connecting column 711 and a first limiting stop 712. A shaft hole 7111 is formed in the connecting column 711. The positioning portion 72 includes a positioning portion body 721, a positioning protrusion 724, and a gripping portion 73. The positioning portion body 721 is connected to the top of the connecting portion 71, and the bottom of the positioning portion body 721 is connected to the first limiting stop 712. The gripping portion 73 is connected to the top of the positioning portion body 721, and the positioning protrusion 724 is arranged on the front side of the positioning portion body 721. Elastic openings 723 are respectively formed at the left and right ends of the positioning portion body 721. The elastic openings 723 are strip-shaped and extend in the up and down direction. The portions of the positioning portion body 721 located on the left side of the left elastic opening 723 and the portions of the positioning portion body 721 located on the left side of the left elastic opening 723 are both formed as elastic arms 725, and a plugging protrusion 722 is formed on each elastic arm 725.

[0101] An anti - detachment structure 42 is formed on the outer air guide plate 4. The anti - detachment structure 42 is a convex structure formed on the outer air guide plate 4. The anti - detachment structure 42 is provided on the outer air guide plate 4 and is located at the rear side of the outer air guide plate 4 (i.e., the side of the outer air guide plate 4 adjacent to the inner air guide plate 5). An installation structure may be formed on the inner air guide plate 5. This installation structure is used to install and position the connecting piece 7 on the inner air guide plate 5, so that the connecting piece 7 is fixed relative to the air guide component body 401. The installation structure includes an avoidance opening 512, an installation hole 521, and a limit buckle 511. The installation hole 521 is formed on the inner extension part 52. A second limit stop 522 is formed on the inner peripheral wall of the installation hole 521. The second limit stop 522 is annular. A third rib 524 is formed on the upper surface of the second limit stop 522. The third rib 524 extends along the circumferential direction of the second limit stop 522 and is annular. An avoidance opening 512 is formed at the lower end of the inner air guide plate body 51. The avoidance opening 512 penetrates the inner air guide plate body 51 in the front - to - back direction. The avoidance opening 512 communicates with the installation hole 521 located on the inner extension part 52. The limit buckle 511 is provided on the inner air guide plate body 51 and is located at the rear side of the inner air guide plate body 51 (i.e., the side of the inner air guide plate body 51 away from the outer air guide plate 4). There are two limit buckles 511. The two limit buckles 511 are respectively located on the left and right sides of the positioning part body 721 and are respectively located on the left and right sides of the avoidance opening 512. The connecting piece 7 can be an integrally formed part, which can simplify the processing and forming process of the connecting piece 7. The anti - detachment structure 42 can be integrally formed with the outer air guide plate 4, and the limit buckle 511 can be integrally formed with the inner air guide plate 5.

[0102] A part of the bottom wall of the air outlet channel 201 bulges upward to form a water - blocking bulge 203. The water - blocking bulge 203 is annular. A rotation hole 202 is defined on the inner peripheral side of the water - blocking bulge 203. A first rib 204 is formed on the upper surface of the water - blocking bulge 203. The first rib 204 is annular and surrounds the circumference of the rotation hole 202. The first rib 204 is spaced apart from the circumference of the rotation hole 202 in the radial direction. A shaft sleeve 21 is provided between the inner extension part 52 and the inner peripheral wall of the rotation hole 202. A part of the second limit stop 522 on the inner extension part 52 extends into the shaft sleeve 21. A second rib 523 is provided on the bottom surface of the inner extension part 52. The second rib 523 abuts against the shaft sleeve 21 in the up - and - down direction. The protective part 22 includes a connected protective ring 221 and connecting ribs 222. The above - mentioned through - hole 2211 is defined inside the protective ring 221. The protective ring 221 is located on the side of the shaft sleeve 21 adjacent to the driving mechanism 30. There is a gap between the protective ring 221 and the shaft sleeve 21 in the axial direction, which can avoid interference between the shaft sleeve 21 and the protective ring 221 during the installation process. There are four connecting ribs 222. The four connecting ribs 222 can be arranged at intervals along the circumferential direction of the protective ring 221. The lower end of each connecting rib 222 is connected to the protective ring 221, and the upper end of each connecting rib 222 extends upward and is connected to the air outlet frame 20.

[0103] The bushing 21 includes a bushing body 210, a first limiting protrusion 211, and a second limiting protrusion 212. The first limiting protrusion 211 and the second limiting protrusion 212 are both formed on the outer peripheral wall of the bushing body 210. The first limiting protrusion 211 and the second limiting protrusion 212 are arranged at intervals along the axial direction of the bushing body 210, and the first limiting protrusion 211 is located above the second limiting protrusion 212. Four relief notches 213 are formed on the bushing body 210. The four relief notches 213 are arranged at intervals along the circumferential direction of the bushing body 210. Each relief notch 213 penetrates through the bushing body 210 and the second limiting protrusion 212 along the wall thickness direction of the bushing body 210, and each relief notch 213 penetrates through the lower end surface of the bushing body 210.

[0104] When the bushing 21 is installed at the rotating hole 202, the inner peripheral wall of the rotating hole 202 is received in the fitting groove 214 defined by the first limiting protrusion 211, the second limiting protrusion 212, and the outer peripheral wall of the bushing body 210. The first limiting protrusion 211 is located on the upper side of the rotating hole 202 in the axial direction, and the second limiting protrusion 212 is located on the lower side of the rotating hole 202 in the axial direction. The first limiting protrusion 211 and the second limiting protrusion 212 are respectively in contact with the two axial end faces of the rotating hole 202, so that the bushing 21 can be reliably installed at the rotating hole 202, and the installation of the bushing 21 is convenient. The second rib 523 on the bottom surface of the air guiding member 40 abuts against the upper surface of the first limiting protrusion 211 of the bushing 21, reducing the cold air in the air outlet channel 201 from blowing towards the driving mechanism 30, and reducing the contact area between the air guiding member 40 and the bushing 21, and reducing the frictional wear between the air guiding member 40 and the bushing 21 when the air guiding member 40 rotates. Each relief notch 213 avoids the corresponding connecting rib 222, and a part of each connecting rib 222 is received in the corresponding relief notch 213. The part of the bushing 21 located between adjacent relief notches 213 can be located in the space defined between adjacent connecting ribs 222, which can improve the connection strength between the protective member 22 and the air outlet frame 20, and make the structure more compact.

[0105] When the connecting member 7 is in the first position, the connecting post 711 of the connecting member 7 is received in the mounting hole 521 of the inner extension portion 52 and penetrates downward through the second limiting stopper 522, the bushing 21, and the through hole 2211 of the protective member 22. The anti-electricity shaft 32 includes an anti-electricity shaft body 321 and a limiting flange 322 formed on the outer peripheral wall of the anti-electricity shaft body 321. The limiting flange 322 is located at the lower end of the anti-electricity shaft body 321 and extends circumferentially along the anti-electricity shaft body 321 and is annular. The anti-electricity shaft body 321 penetrates upward through the through hole 2211 and the upper end of the anti-electricity shaft body 321 extends upward into the shaft hole 7111 of the connecting post 711, so that the detachable connection between the air guiding member 40 and the driving mechanism 30 can be realized. When the connecting member 7 is in the first position, the positioning portion body 721 of the connecting member 7 abuts against the wall surface of the inner air guiding plate body 51 away from the outer air guiding plate 4, and the two limiting buckles 511 on the inner air guiding plate body 51 are clamped at the left and right ends of the positioning portion body 721. The anti-detachment structure 42 of the outer air guiding plate 4 is located directly above the positioning protrusion 724 on the positioning portion body 721 and the anti-detachment structure 42 is spaced apart from the positioning protrusion 724 in the vertical direction. The distance between the anti-detachment structure 42 and the positioning protrusion 724 in the vertical direction is the stroke of the connecting member 7. When the connecting member 7 is in the first position, the connecting member 7 can be installed and positioned on the inner air guiding plate 5 through the installation structure provided on the inner air guiding plate 5, so that the connecting member 7 is fixed relative to the air guiding member body 401.

[0106] Optionally, the cross-section of the connecting post 711 can be formed into a polygon, and the cross-section of the portion of the mounting hole 521 that cooperates with the connecting post 711 is also formed into a polygon, and the shape of the cross-section of the portion of the mounting hole 521 that cooperates with the connecting post 711 is adapted to the shape of the cross-section of the connecting post 711. For example, the cross-section of the connecting post 711 can be formed into a hexagon, and the cross-section of the portion of the mounting hole 521 that cooperates with the connecting post 711 is also a hexagon. Thus, by making the cross-section of the connecting post 711 into a polygon and the cross-section of the portion of the mounting hole 521 that cooperates with the connecting post 711 into a polygon, the connecting post 711 and the mounting hole 521 can be stably and reliably matched, and the connecting post 711 can be fixed relative to the inner peripheral wall of the mounting hole 521. When the anti-electricity shaft 32 on the driving mechanism 30 is connected to the connecting post 711 and drives the connecting member 7 to rotate, the connecting post 711 can be prevented from moving relative to the air guiding member body 401, so that the driving mechanism 30 can stably and reliably drive the entire air guiding member 40 to rotate.

[0107] Optionally, the cross-section of the driving shaft 31 can also be a polygon (such as a hexagon), the portion of the anti-electricity shaft body 321 that cooperates with the shaft hole 7111 of the connecting post 711 can also be formed into a polygon (such as a hexagon), and the shaft hole 7111 in the connecting post 711 can also be formed into a polygon (such as a hexagon).

[0108] When the connecting member 7 moves downward from the second position to the first position, the insertion and extraction protrusion 722 on the positioning part body 721 moves downward with the positioning part body 721 and passes through the limiting groove defined by the limiting buckle 511 and the inner air guide plate body 51. The insertion and extraction protrusion 722 is squeezed. When the insertion and extraction protrusion 722 moves below the limiting buckle 511, the insertion and extraction protrusion 722 disengages from the above-mentioned limiting groove, and the insertion and extraction protrusion 722 resets and makes a sound, thereby prompting the operator that the connecting member 7 has been inserted downward into the mounting hole 521 and is installed in place. And at this time, the limiting buckle 511 is located above the insertion and extraction protrusion 722, and can further limit the connecting member 7 in the upward direction, so as to better position the connecting member 7 in the first position.

[0109] When the air guide component 40 needs to be installed into the air outlet passage 201 of the air conditioner, the connecting member 7 can be pressed downward, so that the connecting member 7 moves downward from the second position to the first position. At this time, the connecting part 71 of the connecting member 7 is fitted into the mounting hole 521, and the connecting part 71 is fixed relative to the mounting hole 521. At the same time, the connecting column 711 is connected to the anti-electricity shaft 32, and the connecting member 7 is fitted with the mounting structure on the inner air guide plate 5. The connecting member 7 is installed and positioned in the first position through the mounting structure, thus realizing the connection between the air guide component 40 and the driving mechanism 30, realizing the installation of the air guide component 40, and the installation is convenient and easy to operate.

[0110] When the air guide component 40 needs to be removed from the air outlet passage 201 of the air conditioner, the connecting member 7 can be pulled upward, so that the connecting member 7 moves upward from the first position to the second position, so that the connecting column 711 of the connecting member 7 is separated from the anti-electricity shaft 32. At this time, at least a part of the connecting part 71 disengages from the mounting hole 521, thus realizing the separation between the air guide component 40 and the driving mechanism 30, realizing the disassembly of the air guide component 40, and the disassembly is convenient and easy to operate. When the connecting member 7 moves upward from the first position to the second position, the insertion and extraction protrusion 722 on the positioning part body 721 moves upward with the positioning part body 721 and passes through the above-mentioned limiting groove. The insertion and extraction protrusion 722 is squeezed. When the insertion and extraction protrusion 722 moves above the limiting buckle 511, the insertion and extraction protrusion 722 disengages from the above-mentioned limiting groove, and the insertion and extraction protrusion 722 resets and makes a sound, thereby prompting the operator that the connecting member 7 has been pulled upward in place. And at this time, the limiting buckle 511 is located below the insertion and extraction protrusion 722, and can limit the connecting member 7 in the downward direction to prevent the connecting member 7 from falling downward. It should be noted that when the connecting member 7 moves upward to the second position, the positioning protrusion 724 of the connecting member 7 abuts against the anti-detachment structure 42 on the outer air guide plate 4 in the up and down direction. Through the common limiting action of the anti-detachment structure 42 and the mounting structure, the connecting member 7 can be prevented from falling off the air guide component body 401.

[0111] Among them, the maximum projection of the cross-section of the electric shock prevention shaft 32 on the reference plane can be the first projection, and the projection of the cross-section of the part of the electric shock prevention shaft 32 with the limiting flange 322 on the reference plane is the first projection; the minimum projection of the cross-section of the perforation 2211 on the reference plane can be the second projection. For example, the projection of the cross-section at the lower end of the perforation 2211 on the reference plane is the second projection, and the second projection is located within the first projection. Moreover, the lower end surface of the protective ring 221 constitutes the first limiting surface 2212, and the upper surface of the limiting flange 322 constitutes the second limiting surface 3221. The first limiting surface 2212 and the second limiting surface 3221 are opposite and spaced apart in the up and down direction. The stroke of the connecting member 7 is L1, the distance between the first limiting surface 2212 and the second limiting surface 3221 in the axial direction (such as the up and down direction) is d, the axial mating length between the air guiding member 40 and the electric shock prevention shaft 32 is L2, and the axial mating length between the electric shock prevention shaft 32 and the driving shaft 31 is L3. The sum of d and L2 is less than L1 and d is less than L3.

[0112] In the process of disassembling the air guiding member 40 like this, when pulling up the connecting member 7 and moving the connecting member 7 from the first position to the second position, if the electric shock prevention shaft 32 follows the connecting member 7 to move upward, due to the blocking effect of the protective member 22 on the electric shock prevention shaft 32, it can be avoided that the electric shock prevention shaft 32 escapes through the perforation 2211 and the rotating hole 202, so that the probability of the electric shock prevention shaft 32 detaching from the driving shaft 31 can be avoided or significantly reduced, the safety is improved, and it better meets the safety regulations requirements. Specifically, if the electric shock prevention shaft 32 follows the connecting member 7 to move upward, when the electric shock prevention shaft 32 moves to contact the first limiting surface 2212 and the second limiting surface 3221, the electric shock prevention shaft 32 cannot continue to move with the connecting member 7, while the connecting member 7 can continue to move until the connecting member 7 detaches from the electric shock prevention shaft 32. In this way, it can be avoided that the electric shock prevention shaft 32 follows the connecting member 7 through the perforation 2211 and the rotating hole 202 and moves into the air outlet channel 201, reducing the risk of the electric shock prevention shaft 32 escaping. At the same time, it can be avoided that the electric shock prevention shaft 32 detaches from the driving shaft 31 during the process of moving with the connecting member 7, further improving the safety and better meeting the safety regulations requirements; moreover, at the same time, it can further avoid the situation of being stuck and unable to be disassembled during the process of disassembling the air guiding member 40, ensuring that the air guiding member 40 can be disassembled.

[0113] Referring to Figures 1 - 6 , the air conditioner according to the second aspect embodiment of the present invention includes: the air outlet frame assembly 200 according to the above first aspect embodiment of the present invention.

[0114] Optionally, the air conditioner can be a split-type air conditioner or an integrated air conditioner. When the air conditioner is a split-type air conditioner, it can be a split wall-mounted air conditioner or a split floor-standing air conditioner. When the air conditioner is a split-type air conditioner, the air conditioner includes an indoor unit 100 and an outdoor unit, and the indoor unit includes the above-mentioned air outlet frame assembly 200.

[0115] Specifically, the indoor unit 100 of the air conditioner includes a casing 10, a heat exchanger component, a fan component, an air outlet frame 20, and a wind guiding component 40. The casing 10 includes a front panel 11, a rear panel 12, a top cover 14, and a base 13. The air outlet frame 20 is connected to the front end of the rear panel 12, the front panel 11 is connected to the front side of the air outlet frame 20, and the top cover 14 and the base 13 are respectively connected to the upper and lower sides of the rear panel 12. The heat exchanger component and the fan component are both arranged inside the casing 10 and in the space defined by the air outlet frame 20 and the casing 10. At least one air outlet channel 201 is formed on the air outlet frame 20, and the wind guiding component 40 is rotatably arranged in the air outlet channel 201. A first air outlet 16 is formed at a position on the casing 10 opposite to the air outlet side of the air outlet channel 201. The first air outlet 16 can be defined between the front panel 11 and the rear panel 12, and a first air inlet 15 is formed on the rear panel 12. A switch door 101 can also be provided at the first air outlet 16. The switch door 101 is slidably arranged on the casing 10 along the circumferential direction of the casing 10. By sliding the switch door 101, the opening and closing of the air outlet can be realized.

[0116] When the air conditioner is working, the switch door 101 opens the first air outlet 16, and the fan component works to drive the external air flow to enter the casing 10 from the first air inlet 15 and exchange heat with the heat exchanger component. The heat-exchanged air flow flows through the air outlet channel 201. During the process of the air flow flowing through the air outlet channel 201, the air flow is guided or diffused by the wind guiding component 40, and finally blows out from the first air outlet 16 into the room, so that the indoor environmental temperature can be adjusted. When the air conditioner is shut down, the switch door 101 closes the first air outlet 16.

[0117] Optionally, the working modes of the air conditioner can include a normal air supply mode and a draft-free mode. When the air conditioner is in the normal air supply mode, the wind guiding component 40 rotates to a position where the air outlet end of the air outlet channel 201 is opened, and the air flow mainly flows from one side or both sides of the wind guiding component 40 to the first air outlet 16. When the air conditioner is in the draft-free mode, the wind guiding component 40 rotates to a position where the air outlet end of the air outlet channel 201 is closed, and the air flow passes through the wind guiding component 40 and is diffused by the wind guiding component 40, and blows out more gently from the first air outlet 16.

[0118] Optionally, one air outlet channel 201 can be formed on the air outlet frame 20. At this time, the first air outlet 16 is one and is opposite to the air outlet channel 201. The fan component can include a single impeller, and the impeller can be a cross-flow impeller.

[0119] Optionally, two air outlet channels 201 may also be formed on the air outlet frame 20. At this time, there are two first air outlets 16, and the two first air outlets 16 are respectively opposite to the two air outlet channels 201. The fan component may include two wind wheels, both of the two wind wheels may be cross-flow wind wheels, the two wind wheels are respectively arranged corresponding to the two air outlet channels 201, and the two wind wheels respectively drive the air flow into the corresponding air outlet channels 201.

[0120] For the air conditioner according to the embodiment of the present invention, by providing the above-mentioned air outlet frame assembly 200, during the process of disassembling the air guiding component 40, the probability of the anti-electricity shaft 32 disengaging from the driving shaft 31 can be avoided or significantly reduced, the safety is improved, and the requirements of safety regulations are better met.

[0121] In some embodiments of the present invention, the air conditioner indoor unit 100 may include a heat exchange unit and an air treatment unit. The heat exchange unit and the air treatment unit are located in the housing 10, and the heat exchange unit and the air treatment unit may be arranged along the length direction of the housing 10 (for example, the up-down direction). Among them, the heat exchange unit includes the above-mentioned heat exchanger component, fan component, air outlet frame 20 and air guiding component 40. The air treatment unit may have at least one of the functions of fresh air, humidification, and purification, and the air treatment unit can improve the indoor environmental quality.

[0122] A fresh air inlet, a second air inlet 17, a second air outlet 18 and a third air outlet 19 may also be formed on the housing 10. The fresh air inlet may be formed at the rear side of the housing 10, the second air outlet 18 may be formed at the left front side and / or the right front side of the housing 10, and the third air outlet 19 may be formed at the front side of the housing 10.
