[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0040] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0041] like Figures 1 to 4 As shown, the air conditioner 100 according to an embodiment of the present invention includes: an air duct assembly 1 and a drive motor 4. The air duct assembly 1 is provided with a connecting post 2 and a positioning structure 3. The drive motor 4 is fixedly connected to the connecting post 2 by fasteners 5. The positioning structure 3 is used to restrict the degree of freedom of movement of the drive motor 4 in the radial and circumferential directions. Therefore, during the process of installing the drive motor 4 onto the air duct assembly 1, after the drive motor 4 cooperates with the positioning structure 3, the positioning structure 3 can better maintain the position of the drive motor 4 on the air duct assembly 1, so as to avoid the drive motor 4 from moving radially or rotating circumferentially. Thus, it is not necessary to support the drive motor 4 during the process of fixing the drive motor 4 to the connecting post 2 by the fasteners 5. At the same time, the positioning between the drive motor 4 and the connecting post 2 can be realized, so as to improve the installation efficiency of the drive motor 4 while ensuring the installation accuracy of the drive motor 4. Furthermore, it is understood that the drive motor 4 can be connected to the connecting column 2 along the axial direction of the drive motor 4 via the fastener 5, thereby restricting the movement of the drive motor 4 in the radial, circumferential and axial directions through the cooperation of the connecting column 2 and the positioning structure 3, so as to improve the stability of the drive motor 4 after installation.

[0042] Specifically, taking the air conditioner 100 as a hanging machine, and taking the axial direction of the driving motor 4 extending horizontally as an example, the positioning structure 3 can limit the driving motor 4 in the front-back-up-down direction, and can prevent the driving motor 4 from rotating around the center axis in the clockwise or counterclockwise direction during installation, so as to realize the pre-positioning of the driving motor 4 on the air duct assembly 1, so as to keep the driving motor 4 in the accurate position connected with the connecting column 2, so as to facilitate the subsequent fixation of the driving motor 4 on the connecting column 2 through the fastener 5. It should be noted that the above is only an example of one type of air conditioner 100 and one type of installation direction of the driving motor 4, and is not a limitation on the type of air conditioner 100 and the installation direction of the driving motor 4. For example, the air conditioner 100 can also be a cabinet machine, a window type, etc.

[0043] According to the air conditioner 100 of the embodiment of the present application, the positioning structure 3 can better keep the position of the driving motor 4 on the air duct assembly 1, so as to avoid the radial movement or circumferential rotation of the driving motor 4, so as to avoid holding the driving motor 4 during the fixation of the driving motor 4 to the connecting column 2 through the fastener 5, and can realize the positioning between the driving motor 4 and the connecting column 2, so as to improve the installation efficiency of the driving motor 4 while ensuring the installation accuracy of the driving motor 4.

[0044] According to some embodiments of the present application, the positioning structure 3 comprises a positioning rib 31 arranged on the outer circumferential side of the driving motor 4, and at least part of the positioning rib 31 is arranged opposite to the outer circumferential surface of the driving motor 4. Therefore, through the opposite part of the positioning rib 31 and the outer circumferential surface of the driving motor 4, the movement of the driving motor 4 towards the outside of the positioning rib 31 can be limited, and the outside of the positioning rib 31 here refers to the side of the positioning rib 31 away from the driving motor 4 in the radial direction of the driving motor 4, so that the positioning rib 31 can at least limit the activity freedom of the driving motor 4 in the radial direction of the driving motor 4. Among them, since the positioning rib 31 has simple structure and good limiting effect, the structure complexity of the positioning structure 3 can be simplified while ensuring the limiting effect of the positioning rib 31 on the driving motor 4, so as to reduce the processing and molding difficulty of the positioning structure 3.

[0045] According to some embodiments of the present application, the side surface opposite to the outer circumferential surface of the driving motor 4 of the positioning rib 31 is a positioning surface 311, and the profile of the positioning surface 311 is similar to the profile of the outer circumferential surface of the driving motor 4 in the circumferential direction of the driving motor 4. That is, the shape of the positioning surface 311 is similar to the shape of the part on the outer circumferential surface of the driving motor 4 corresponding to the positioning surface 311. For example, if the profile of the part on the outer circumferential surface of the driving motor 4 opposite to one of the positioning surfaces 311 is arc-shaped, the shape of the positioning surface 311 is also arc-shaped. If the profile of the part on the outer circumferential surface of the driving motor 4 opposite to one of the positioning surfaces 311 is straight, the shape of the positioning surface 311 is also straight. Therefore, in the circumferential direction of the driving motor 4, the positioning position of the driving motor 4 can be increased by the positioning surface 311, so as to improve the pre-positioning accuracy of the positioning rib 31 to the driving motor 4.

[0046] According to some embodiments of the present application, the positioning rib 31 is provided with a plurality of positioning ribs 31 arranged at intervals in the circumferential direction of the driving motor 4. That is, the positioning structure 3 can limit the freedom of movement of the driving motor 4 in the radial direction through the plurality of positioning ribs 31 at multiple positions in the circumferential direction of the driving motor 4. Therefore, through the cooperation of the plurality of positioning ribs 31, the positioning position of the driving motor 4 can be increased by the positioning structure 3, so as to improve the pre-positioning effect of the positioning structure 3 to the driving motor 4.

[0047] According to some embodiments of the present application, the driving motor 4 comprises a motor body 41 and a boss 42 provided on the outer circumferential surface of the motor body 41, and the plurality of positioning ribs 31 comprises a first positioning rib 31a and a second positioning rib 31b, and a first positioning space 32 is defined between the first positioning rib 31a and the second positioning rib 31b, and at least part of the boss 42 is located in the first positioning space 32. Specifically, the first positioning rib 31a and the second positioning rib 31b are located on opposite sides of the boss 42 in the circumferential direction of the driving motor 4, for example, the first positioning rib 31a is located on one side of the boss 42 in the clockwise direction, and the first positioning rib 31a can limit the rotation of the boss 42 in the clockwise direction, and the second positioning rib 31b is located on one side of the boss 42 in the counterclockwise direction, and the second positioning rib 31b can limit the rotation of the boss 42 in the counterclockwise direction. Therefore, through the cooperation of the first positioning rib 31a and the second positioning rib 31b, the rotation of the boss 42 in the circumferential direction of the driving motor 4 can be prevented, so as to prevent the driving motor 4 from rotating in the circumferential direction, and through the part of the first positioning rib 31a and the second positioning rib 31b opposite to the outer circumferential surface of the driving motor 4, the freedom of movement of the driving motor 4 in the radial direction can be limited, in other words, the first positioning rib 31a and the second positioning rib 31b can limit the movement of the driving motor 4 in the radial direction and the circumferential direction, and the structure complexity of the positioning structure 3 can be simplified, so as to reduce the difficulty of processing and forming of the positioning structure 3.

[0048] According to some embodiments of the present application, the first positioning rib 31a and the second positioning rib 31b further define a second positioning space 33 in communication with the first positioning space 32, and at least part of the motor body 41 is located in the second positioning space 33. That is, on the basis of limiting the freedom of movement of the boss 42 of the driving motor 4 by the part of the first positioning rib 31a and the second positioning rib 31b defining the first positioning space 32, the part of the first positioning rib 31a and the second positioning rib 31b defining the second positioning space 33 can better limit the freedom of movement of the motor body 41 of the driving motor 4. Therefore, the limiting position of the driving motor 4 by the first positioning rib 31a and the second positioning rib 31b can be increased, so that the accuracy of the pre-positioning of the driving motor 4 by the positioning structure 3 can be improved to accurately position the driving motor 4 at the position connected with the connecting column 2.

[0049] In one specific example, the positioning surface 311 of the first positioning rib 31a includes a first positioning area and a second positioning area, the positioning surface 311 of the second positioning rib 31b includes a third positioning area and a fourth positioning area, the first positioning area and the third positioning area are located on opposite sides of the boss 42 and jointly define the first positioning space 32, the profiles of the first positioning area and the third positioning area are similar to the profiles of the opposite sides of the boss 42 and are both linear, the second positioning area and the fourth positioning area are located on the outer circumferential side of the motor body 41 and jointly define the second positioning space 33, the profiles of the second positioning area and the fourth positioning area are similar to the profiles of the outer sides of the opposite sides of the motor body 41 and are both arc-shaped, so that the profiles of the positioning surfaces 311 of the first positioning rib 31a and the second positioning rib 31b can better fit the different outer circumferential profiles of the motor body 41 and the boss 42, to improve the pre-positioning effect of the first positioning rib 31a and the second positioning rib 31b on the driving motor 4.

[0050] According to some embodiments of the present application, the first positioning rib 31a and the second positioning rib 31b are symmetrically arranged. Specifically, the first positioning rib 31a and the second positioning rib 31b are symmetrically arranged with respect to the center line of the boss 42 in the direction in which the first positioning rib 31a and the second positioning rib 31b are arranged. Therefore, the design and molding difficulty of the first positioning rib 31a and the second positioning rib 31b can be reduced, and the balance of the limiting of the driving motor 4 by the first positioning rib 31a and the second positioning rib 31b can be ensured, to improve the pre-positioning effect of the positioning structure 3 on the driving motor 4.

[0051] According to some embodiments of this utility model, the air duct assembly 1 is further provided with a support rib 6, and the drive motor 4 is supported on the support rib 6. The support rib 6 is located between the first positioning rib 31a and the second positioning rib 31b. By providing the support rib 6, the drive motor 4 can be supported from the side facing the air duct assembly 1, thereby preventing the drive motor 4 from swaying radially. Therefore, by placing the support between the first positioning rib 31a and the second positioning rib 31b, the support stability of the drive motor 4 in the area between the first positioning rib 31a and the second positioning rib 31b can be better enhanced, thus stably maintaining the installation position of the drive motor 4. In a specific example, the first positioning rib 31a and the second positioning rib 31b are symmetrically distributed on opposite sides of the support rib 6.

[0052] According to some embodiments of this utility model, the positioning rib 31 is connected to the connecting column 2. Both the positioning rib 31 and the connecting column 2 are disposed on the air duct assembly 1, meaning that both the positioning rib 31 and the connecting column 2 are directly connected to the air duct assembly 1. The positioning rib 31 is connected to the connecting column 2, and the connecting column 2 is also connected to the air duct assembly 1 via the positioning rib 31. In other words, the positioning rib 31 increases the connection points between the connecting column 2 and the air duct assembly 1, and the connecting column 2 increases the connection points between the positioning rib 31 and the air duct assembly 1, thereby improving the connection strength between the positioning rib 31, the connecting column 2, and the air duct assembly 1.

[0053] According to some embodiments of this utility model, the end of the positioning rib 31 connected to the air duct assembly 1 is a fixed end, and the end of the positioning rib 31 extending away from the air duct assembly 1 is a free end. From the fixed end to the free end, the width of the positioning rib 31 in the radial direction of the drive motor 4 gradually decreases. This reduces the difficulty of removing the mold from the positioning rib 31. Simultaneously, the positioning surface 311 can be formed as an inclined guide surface; that is, from the fixed end to the free end, the positioning surface 311 extends inclined away from the drive motor 4. This allows the positioning surface 311 to better guide the drive motor 4 into the space between multiple positioning ribs 31, reducing the difficulty of fitting the drive motor 4 with the positioning structure 3.

[0054] According to some embodiments of this utility model, such as Figures 7-9 As shown, the outer peripheral surface of the drive motor 4 is spaced apart from the positioning rib 31, and the spacing between the outer peripheral surface of the drive motor 4 and the positioning rib 31 is (e.g., ...). Figure 9W1) is not greater than 0.5 mm. That is, the interval between the outer circumferential surface of the driving motor 4 and the positioning rib 31 in the radial direction is controlled in the range of 0 (not including 0) to 0.5 (including 0.5) mm, for example, the distance between the outer circumferential surface of the driving motor 4 and the positioning rib 31 in the radial direction can be 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm, 0.5 mm, and the like.

[0055] It can be understood that the driving motor 4 will vibrate during operation. By spacing the outer circumferential surface of the driving motor 4 from the positioning rib 31, the vibration of the driving motor 4 can be avoided from being transmitted to the air duct assembly 1 through the connecting column 2 to cause the air duct assembly 1 to resonate and generate noise. If the interval between the outer circumferential surface of the driving motor 4 and the positioning rib 31 is too large, the positioning rib 31 will lose the positioning effect on the driving motor 4. Therefore, by controlling the interval between the outer circumferential surface of the driving motor 4 and the positioning rib 31 in the radial direction in the range of 0 (not including 0) to 0.5 (including 0.5) mm, the positioning effect of the positioning rib 31 on the driving motor 4 can be ensured, and at the same time, a certain space is reserved for the vibration of the driving motor 4 to avoid resonance noise.

[0056] According to some embodiments of the present application, as shown in Figure 5 and Figure 6 , the part of the positioning rib 31 opposite to the outer circumferential surface of the driving motor 4 along the radial direction of the driving motor 4 is a positioning portion 312, and the size of the positioning portion 312 in the axial direction of the driving motor 4 (for example Figure 6 H1) is not less than 6 mm. That is, the length of the positioning rib 31 limiting the driving motor 4 in the axial direction of the driving motor 4 is not less than 6 mm. It can be understood that the larger the size of the positioning portion 312 in the axial direction of the driving motor 4, the better the positioning effect of the positioning rib 31 on the driving motor 4. Therefore, the positioning effect of the positioning rib 31 on the driving motor 4 can be better guaranteed. For example, the size of the positioning portion 312 in the axial direction of the driving motor 4 can be 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, and the like, which is not limited here.

[0057] According to some embodiments of the present application, as shown in Figure 2 , Figure 4 and Figure 9As shown, the positioning structure 3 comprises a positioning column 34 extending along the axial direction of the driving motor 4, and the driving motor 4 is formed with a positioning hole 431 which is insertedly matched with the positioning column 34. Therefore, when the driving motor 4 is installed to the air duct assembly 1, the positioning column 34 is insertedly aligned with the positioning hole 431, and the driving motor 4 can be well limited in the freedom of movement relative to the positioning column 34 through the matching of the positioning column 34 and the positioning hole 431, so that the freedom of movement of the driving motor 4 relative to the air duct assembly 1 can be limited to maintain the position of the driving motor 4 on the air duct assembly 1, and meanwhile, the positioning between the driving motor 4 and the connecting column 2 can be realized to simplify the installation process of the driving motor 4 and improve the installation efficiency of the driving motor 4.

[0058] In some embodiments, the positioning column 34 is located at the outer circumferential side of the motor body 41, and the connecting lug 43 is arranged on the outer circumferential surface of the motor body 41, so that the alignment of the positioning column 34 and the positioning hole 431 can be observed, the difficulty of inserting the positioning column 34 into the positioning hole 431 can be reduced, and the assembly efficiency of the driving motor 4 can be improved.

[0059] According to some embodiments of the present application, the positioning column 34 and the positioning hole 431 are both arranged in multiple numbers along the circumferential direction of the driving motor 4. That is, the driving motor 4 is formed with multiple positioning holes 431 arranged along the circumferential direction, and the air duct assembly 1 is arranged with multiple positioning columns 34 arranged along the circumferential direction of the driving motor 4, and the multiple positioning holes 431 and the multiple positioning columns 34 can be insertedly matched one by one, so that the matching positions of the positioning structure 3 to the driving motor 4 can be increased, and meanwhile, the multiple positioning columns 34 inserted into the multiple positioning holes 431 can prevent the driving motor 4 from rotating along the circumferential direction relative to the air duct assembly 1, so as to improve the reliability of the positioning structure 3 to the driving motor 4.

[0060] According to some embodiments of the present application, the at least two positioning columns 34 are distributed on opposite sides of the driving motor 4. In this way, the at least two positioning columns 34 can be positioned to the driving motor 4 from opposite sides of the driving motor 4 to ensure the balance of the positioning to the driving motor 4.

[0061] According to some embodiments of the present application, the driving motor 4 comprises a connecting lug 43 connected with the connecting column 2, the connecting lug 43 is formed with a connecting hole connected with the connecting column 2, and the positioning hole 431 is formed on the connecting lug 43 and spaced apart from the connecting hole. That is, the connecting hole and the positioning hole 431 are both independently formed on the connecting lug 43, so that the positioning hole 431 can be arranged on the connecting lug 43 by fully utilizing the space on the connecting lug 43, and meanwhile, the positioning hole 431 and the connecting hole can be prevented from interfering with each other to reduce the difficulty of positioning and installation.

[0062] According to some embodiments of the present application, as shown in Figure 8 and Figure 9As shown, the positioning column 34 is arranged in a spaced manner with the inner circumferential surface of the positioning hole 431, and the distance between the outer circumferential surface of the positioning column 34 and the inner circumferential surface of the positioning hole 431 is in the range of 0 (not including 0) to 0.1 (including 0.1) mm (as shown by w2 in the middle). Figure 9 That is, the spacing between the outer circumferential surface of the positioning column 34 and the inner circumferential surface of the positioning hole 431 is controlled in the range of 0 (not including 0) to 0.1 (including 0.1) mm, for example, the distance between the outer circumferential surface of the positioning column 34 and the inner circumferential surface of the positioning hole 431 can be 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, etc.

[0063] It can be understood that the driving motor 4 will vibrate during operation. By arranging the outer circumferential surface of the positioning column 34 and the inner circumferential surface of the positioning hole 431 in a spaced manner, the vibration of the driving motor 4 can be avoided from being transmitted to the air duct assembly 1 through the connecting column 2 to cause the air duct assembly 1 to produce resonance noise. If the spacing between the outer circumferential surface of the positioning column 34 and the inner circumferential surface of the positioning hole 431 is too large, the positioning of the driving motor 4 by the positioning column 34 will fail. Therefore, by controlling the spacing between the outer circumferential surface of the positioning column 34 and the inner circumferential surface of the positioning hole 431 in the range of 0 (not including 0) to 0.1 (including 0.1) mm, the positioning effect of the driving motor 4 by the positioning column 34 can be ensured, and at the same time, a certain space is reserved for the vibration of the driving motor 4 to avoid resonance noise.

[0064] In one specific example, the positioning structure 3 is arranged in a spaced manner with the driving motor 4. The spacing between the positioning structure 3 and the driving motor 4 can ensure the positioning effect of the driving motor 4 by the positioning structure 3, while reducing the indirect connection position between the driving motor 4 and the air duct assembly 1 to prevent the air duct assembly 1 from resonating due to the vibration of the driving motor 4.

[0065] According to some embodiments of the present application, as shown in Figure 6 The free end of the positioning column 34 extends to the side of the positioning hole 431 away from the air duct assembly 1, and the height of the free end of the positioning column 34 protruding out of the positioning hole 431 is in the range of 0 (not including 0) to 0.1 (including 0.1) mm (as shown by w3 in the middle). Figure 6h2) is not less than 1.5 mm. That is, the height of the positioning column 34 extending out of the positioning hole 431 is controlled in the range of 1.5 mm or greater than 1.5 mm. Among them, it can be understood that the height of the positioning column 34 extending out of the positioning hole 431 is too small, the higher the risk of the positioning column 34 from the positioning hole 431. Therefore, the plug-in fit relationship between the positioning column 34 and the positioning hole 431 can be better maintained, so as to ensure the reliability of the positioning column 34 positioning the drive motor 4. For example, the height of the free end of the positioning column 34 extending out of the positioning hole 431 can be 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, etc. Herein, no specific limitation is made.
