Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular to a motor fixing structure and an air conditioner cabinet. Background Art

[0002] Air conditioners are often equipped with an exhaust assembly for distributing air. The exhaust assembly typically includes a drive motor and an exhaust impeller driven by the drive motor. The drive motor is fixed to the air outlet mesh cover via a motor gland, which is fixedly connected to the air outlet mesh cover.

[0003] However, the existing process of assembling the motor gland to the air outlet grille is relatively inefficient. Utility Model Content

[0004] The first object of the present utility model is to provide a motor fixing structure to solve the technical problem of low efficiency in the existing process of assembling the motor gland to the air outlet mesh cover.

[0005] The motor fixing structure provided by the utility model includes an air outlet mesh cover and a motor pressure cover fixedly connected to the air outlet mesh cover, and an installation cavity for accommodating a drive motor is formed between the motor pressure cover and the air outlet mesh cover; the outer edge of the motor pressure cover is provided with a first positioning portion, and the air outlet mesh cover is provided with a second positioning portion, and the second positioning portion is plugged into and matched with the first positioning portion.

[0006] By providing a first positioning portion on the outer edge of the motor gland and providing a second positioning portion on the air outlet grille that plugs and cooperates with the first positioning portion, the motor gland can be positioned by utilizing the plug-in cooperation of the first positioning portion and the second positioning portion during assembly of the motor gland and the air outlet grille. This eliminates the need for repeated alignment during assembly of the motor gland, thereby improving assembly efficiency. Furthermore, the provision of the first and second positioning portions can also limit the circumferential rotation of the motor gland, preventing the motor gland from rotating relative to the air outlet grille.

[0007] In addition, during the assembly process of the motor gland, the plugging process of the first positioning portion and the second positioning portion can be utilized to guide the installation of the motor gland to the air outlet grille, thereby further improving the assembly efficiency of the motor gland.

[0008] Furthermore, the first positioning portion includes multiple positioning notches located on the outer edge of the motor gland, and the second positioning portion includes multiple positioning blocks. The number and position of the positioning blocks correspond to the number and position of the positioning notches, and the multiple positioning notches are plugged into and mate with the multiple positioning blocks in a one-to-one correspondence. This arrangement ensures that after the motor gland is removed from the air outlet grille, there will be no protruding structure on the outer edge of the motor gland, thereby effectively preventing damage caused by bumps and providing a certain degree of protection for the first positioning portion.

[0009] Furthermore, the motor gland has a central positioning hole, and the drive motor has a positioning protrusion on a side facing the motor gland. The central positioning hole is adapted to accommodate and cooperate with the positioning protrusion. This arrangement allows the drive motor to be positioned during assembly of the motor gland and the drive motor by utilizing the accommodation and cooperation between the central positioning hole of the motor gland and the positioning protrusion of the drive motor, thereby improving the installation efficiency of the drive motor.

[0010] Furthermore, the motor gland is provided with multiple groups of heat dissipation holes, spaced apart circumferentially around the central positioning hole. This arrangement allows for the timely dissipation of heat generated by the drive motor, preventing motor malfunctions due to overheating. By providing multiple groups of heat dissipation holes spaced apart circumferentially around the central positioning hole, the heat dissipation area and surface of the motor gland are increased, thereby improving heat dissipation efficiency.

[0011] Furthermore, the heat dissipation hole group includes a plurality of heat dissipation holes, and the plurality of heat dissipation holes in each heat dissipation hole group are spaced apart along the radial direction of the motor gland. This arrangement not only ensures that the motor gland has sufficient heat dissipation area to ensure heat dissipation efficiency, but also ensures that the opening area of ​​each heat dissipation hole is not too large under the same heat dissipation area. On the one hand, it can reduce the entry of impurities into the installation cavity, and on the other hand, it can also ensure the structural strength of the motor gland.

[0012] Furthermore, the heat dissipation holes are long strip holes, and the length direction of the heat dissipation holes extends along the circumference of the motor gland. Through this arrangement, the heat dissipation area of ​​the heat dissipation hole group can be further increased, thereby further improving the heat dissipation efficiency.

[0013] Furthermore, the outer edge of the motor gland is provided with a flange, which is folded away from the air outlet mesh cover. This arrangement plays a certain structural reinforcement role on the outer edge of the motor gland and reduces deformation of the motor gland at the outer edge.

[0014] Furthermore, the motor fixing structure includes connecting screws, the motor gland is also provided with a connecting aperture, and the air outlet grille is provided with a connecting screw hole opposite the connecting aperture, and the connecting screw passes through the connecting aperture and is screwed into the connecting screw hole. This method of connecting the motor gland and the air outlet grille with connecting screws is not only simple in structure but also reliable in connection, ensuring the installation stability of the motor gland.

[0015] Furthermore, the motor gland is provided with a weight-reducing groove, which is located on a side of the motor gland facing away from the air outlet grille. Providing the weight-reducing groove on the motor gland not only reduces the weight of the motor gland but also reduces the material usage, thereby reducing material costs.

[0016] The second object of the present utility model is to provide an air-conditioning cabinet to solve the technical problem of low efficiency in the existing process of assembling the motor gland to the air outlet mesh cover.

[0017] The air-conditioning cabinet provided by the utility model includes an exhaust component and the above-mentioned motor fixing structure, the exhaust component includes a driving motor and an exhaust impeller, the driving motor is accommodated in the mounting cavity, the motor shaft of the driving motor extends out from the air outlet mesh cover, and the exhaust impeller is fixedly sleeved on the motor shaft of the driving motor.

[0018] By setting the above-mentioned motor fixing structure in the air-conditioning cabinet, the air-conditioning cabinet accordingly has all the advantages of the above-mentioned motor fixing structure, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] Figure 1 A side structural cross-sectional view of the air conditioning cabinet provided in this embodiment; Figure 2 for Figure 1 A magnified view of the local structure at point A. Figure 1 and Figure 2 As shown, this embodiment provides a motor fixing structure, including an air outlet mesh cover 100 and a motor pressure cover 200 fixedly connected to the air outlet mesh cover 100, and an installation cavity 300 for accommodating a drive motor 410 is formed between the motor pressure cover 200 and the air outlet mesh cover 100.

[0031] Figure 3 This is a partial structural exploded view of the air conditioning cabinet provided in this embodiment; Figure 4 A front view of the motor fixing structure provided in this embodiment; Figure 5 for Figure 4 A magnified view of the local structure at B in the figure. Figures 3 to 5 As shown, specifically, the outer edge of the motor gland 200 is provided with a first positioning portion, and the air outlet grille 100 is provided with a second positioning portion, and the second positioning portion is plugged into and matched with the first positioning portion.

[0032] By providing a first positioning portion on the outer edge of the motor gland 200 and providing a second positioning portion on the air outlet grille 100 that plugs and cooperates with the first positioning portion, the motor gland 200 can be positioned by utilizing the plug-in cooperation of the first positioning portion and the second positioning portion during the assembly operation of the motor gland 200 and the air outlet grille 100. This eliminates the need for repeated alignment during the assembly process of the motor gland 200, thereby improving the assembly efficiency of the motor gland 200. Furthermore, the provision of the first positioning portion and the second positioning portion can also limit the circumferential rotation of the motor gland 200, preventing the motor gland 200 from rotating relative to the air outlet grille 100.

[0033] In addition, during the assembly process of the motor cover 200, the plugging process of the first positioning part and the second positioning part can also be used to guide the installation of the motor cover 200 to the air outlet grille 100, so as to further improve the assembly efficiency of the motor cover 200.

[0034] Please continue to refer to Figures 3 to 5 In this embodiment, the first positioning portion may include a plurality of positioning notches 210 located on the outer edge of the motor cover 200, and the second positioning portion includes a plurality of positioning blocks 110, wherein the number and positions of the positioning blocks 110 correspond to the number and positions of the positioning notches 210, and the plurality of positioning notches 210 are respectively plugged in and matched with the plurality of positioning blocks 110 in a one-to-one correspondence.

[0035] This form of using the positioning notch 210 to form the first positioning portion and the positioning block 110 to form the second positioning portion, while ensuring reliable positioning of the motor cover 200, also ensures that after the motor cover 200 is removed from the air outlet mesh cover 100, there will be no protruding structure on the outer edge of the motor cover 200, thereby effectively avoiding damage caused by bumps and providing a certain degree of protection for the first positioning portion.

[0036] In addition, this arrangement also allows the operator to intuitively see the fit between the positioning notch 210 and the positioning block 110 through the outer edge of the motor cover 200 when assembling the motor cover 200, thereby facilitating the rapid positioning of the motor cover 200.

[0037] Please continue to refer to Figure 3 and Figure 4 In this embodiment, the motor gland 200 is provided with three positioning notches 210 , and the three positioning notches 210 are arranged at equal intervals along the circumference of the motor gland 200 . Correspondingly, the air outlet grille 100 is provided with three positioning blocks 110 .

[0038] It is understandable that in other embodiments, the positioning notches 210 provided on the motor cover 200 may be of other numbers and arranged in other forms. This embodiment is merely described by taking the example of three positioning notches 210 arranged at equal intervals.

[0039] Please continue to refer to Figure 2 and Figure 3 In this embodiment, the motor gland 200 is provided with a central positioning hole 220 , and the driving motor 410 is provided with a positioning protrusion 411 on a side facing the motor gland 200 , wherein the central positioning hole 220 is used to accommodate and cooperate with the positioning protrusion 411 .

[0040] This arrangement allows the drive motor 410 to be installed and positioned by utilizing the accommodation and cooperation between the central positioning hole 220 of the motor cover 200 and the positioning protrusion 411 of the drive motor 410 when assembling the motor cover 200 and the drive motor 410, thereby improving the installation efficiency of the drive motor 410.

[0041] In this embodiment, the shape of the middle positioning hole 220 is consistent with the shape of the positioning protrusion 411 of the driving motor 410 , so as to limit the circumferential relative rotation between the driving motor 410 and the motor gland 200 .

[0042] Please continue to refer to Figure 3 and Figure 4 In this embodiment, the motor gland 200 may further include a plurality of heat dissipation hole groups 230 , wherein the plurality of heat dissipation hole groups 230 are arranged at intervals along the circumference of the central positioning hole 220 .

[0043] The arrangement of the heat dissipation hole group 230 allows the heat generated by the drive motor 410 to be dissipated promptly, preventing malfunction of the drive motor 410 due to overheating. Furthermore, by providing multiple heat dissipation hole groups 230 and arranging them circumferentially around the central positioning hole 220, the heat dissipation area and heat dissipation surface of the motor gland 200 can be increased, thereby improving heat dissipation efficiency.

[0044] In this embodiment, an air inlet hole connected to the installation cavity 300 can be set on the surface opposite to the air outlet mesh cover 100 and the motor cover 200. This setting allows the airflow driven by the drive motor 410 to flow toward the front surface of the air outlet mesh cover 100 to enter the installation cavity 300 through the air inlet hole, and carry the heat generated by the drive motor 410 to the heat dissipation hole group 230 for discharge, so as to achieve dynamic heat dissipation of the drive motor 410.

[0045] Figure 6 for Figure 4 A magnified view of the local structure at point C in the middle; Figure 7 This is a front view of the motor gland 200 of the motor fixing structure provided in this embodiment. Figure 6 and Figure 7 As shown, in this embodiment, the heat dissipation hole group 230 may include a plurality of heat dissipation holes 231 , wherein the plurality of heat dissipation holes 231 in each heat dissipation hole group 230 are arranged at intervals along the radial direction of the motor gland 200 .

[0046] This arrangement not only ensures that the motor cover 200 has sufficient heat dissipation area to ensure heat dissipation efficiency, but also ensures that the opening area of ​​each heat dissipation hole 231 is not too large under the same heat dissipation area. On the one hand, it can reduce the entry of impurities into the installation cavity 300, and on the other hand, it can also ensure the structural strength of the motor cover 200.

[0047] Please continue to refer to Figure 6 and Figure 7 In this embodiment, the heat dissipation hole 231 can be a long strip hole, wherein the length direction of the heat dissipation hole 231 extends along the circumference of the motor gland 200.

[0048] Through this configuration, the heat dissipation area of ​​the heat dissipation hole group 230 can be further increased, thereby further improving the heat dissipation efficiency.

[0049] Please continue to refer to Figure 2 、 Figure 5 and Figure 7 In this embodiment, a flange 240 is provided on the outer edge of the motor gland 200 , wherein the flange 240 is folded in a direction away from the air outlet grille 100 .

[0050] The arrangement of the flange 240 plays a certain structural reinforcement role on the outer edge of the motor gland 200 , thereby reducing the deformation of the motor gland 200 at the outer edge.

[0051] Please continue to refer to Figure 3 and Figure 6 In this embodiment, the motor fixing structure may further include connecting screws (not shown in the figure), wherein the motor cover 200 is provided with a connecting light hole 250, and the air outlet grille 100 is provided with a connecting screw hole 120 opposite to the connecting light hole 250, and the connecting screw passes through the connecting light hole 250 and is screwed into the connecting screw hole 120.

[0052] This form of connecting the motor gland 200 and the air outlet grille 100 together by using connecting screws is not only simple in structure, but also reliable in connection, thereby ensuring the installation stability of the motor gland 200.

[0053] Please continue to refer to Figure 3 and Figure 7 In this embodiment, the motor gland 200 may further be provided with a weight-reducing groove 260 , wherein the weight-reducing groove 260 is located on a side of the motor gland 200 facing away from the air outlet mesh cover 100 .

[0054] By providing the weight-reducing groove 260 in the motor gland 200 , not only the weight of the motor gland 200 can be reduced, but also the material usage of the motor gland 200 can be reduced, thereby reducing the material cost.

[0055] In addition, please continue to refer to Figure 1 and Figure 2 This embodiment also provides an air-conditioning cabinet, including an exhaust assembly 400 and the above-mentioned motor fixing structure, wherein the exhaust assembly 400 includes a drive motor 410 and an exhaust impeller 420, the drive motor 410 is accommodated in the installation cavity 300, the motor shaft of the drive motor 410 extends out from the air outlet mesh cover 100, and the exhaust impeller 420 is fixedly sleeved on the motor shaft of the drive motor 410.
