[0041] Existing air conditioners are all equipped with a motor bracket for fixing the motor. In order to prevent the motor bracket from being located between the fan and the heat exchanger and affecting the air flow movement and heat exchange efficiency, the motor bracket is set at the air outlet of the front panel to reduce the flow loss between the fan wheel and the heat exchanger and improve the heat exchange efficiency. However, due to the installation position of the motor bracket, the airflow is easily blocked by the motor bracket during the process of being blown out of the air conditioner, forming a backflow airflow and generating abnormal noise.

[0042] In order to solve this technical problem, the utility model provides an air conditioner.

[0043] See also Figures 1 to 7In one embodiment of the present utility model, the air conditioner includes a shell 10, a motor frame 20, and the shell 10 includes a front panel 11, the front panel 11 is provided with an air outlet 12; the motor frame 20 includes a fixing seat 21 and an adapter leg 22, the fixing seat 21 is used to fix the fan 50, and the adapter leg 22 is provided with multiple adapter legs 22 along the circumference of the fixing seat 21 and connected to the edge of the air outlet 12, and a reinforcement groove 24 is formed on the adapter leg 22 with an opening toward the fan 50; the filling piece 30 fills at least one end of the reinforcement groove 24 close to the edge of the air outlet 12, and the filling piece 30 is filled on the inner side of the reinforcement groove 24; thereby increasing the air supply volume of the air conditioner and reducing the noise during operation of the air conditioner.

[0044] In the technical solution of the present invention, the adapter leg 22 of the motor frame 20 is connected to the edge of the air outlet 12, and a reinforcement groove 24 is formed with an opening facing the fan 50, which helps to ensure the stable assembly of the fan 50 on the air conditioner and improve the heat exchange efficiency of the air conditioner. Among them, because the reinforcement groove 24 is arranged toward the fan 50, the reinforcement groove 24, especially the end of the reinforcement groove 24 close to the edge of the air outlet 12, is filled with a filler 30. Combined with the filler 30 filled in the inner side of the reinforcement groove 24, on the one hand, the path of the air flow flowing back to the shell 10 along the reinforcement groove 24 is cut off, the backflow amount is reduced, and the air supply volume of the air conditioner driven by the fan 50 at the same speed is increased. On the other hand, since the backflow of the air flow is blocked, the noise generated by the air flow flowing in the reinforcement groove 24 is eliminated, effectively reducing the noise during the operation of the air conditioner and improving the air supply sound quality.

[0045] Optionally, the front panel 11 and the motor frame 20 are integrally formed, and the motor frame 20 can be integrally formed at the air outlet 12 of the front panel 11 by stamping. In this way, the production and processing of the motor frame 20 is facilitated, and its processing efficiency and processing quality can be guaranteed. Of course, in other embodiments, it can also be integrally formed by casting or injection molding. Among them, the motor frame 20 includes a fixed base 21 and a plurality of adapter legs 22, each adapter leg 22 is arranged at intervals on the periphery of the fixed base 21, and its free end is connected to the edge of the air outlet 12. In this way, through the supporting effect of the adapter legs 22, the fixed base 21 can be stably connected to the air outlet 12, thereby ensuring the stable assembly of the fan 50 on the motor frame 20.

[0046] In addition, on the basis of ensuring a large air supply volume at the air outlet 12 and stable support of the fan 50 by the motor frame 20, the number of the adapter legs 22 can be set arbitrarily, and the filler 30 corresponds to the adapter legs 22 one by one. Specifically, Figure 3 As shown, the number of the adapter legs 22 is 5. Of course, in other embodiments, the number of the adapter legs 22 may also include but is not limited to 3, 4, 6, or 7.

[0047] Specifically, in an embodiment of the present invention, the fan 50 includes a motor 51 fixed to a fixing seat 21, and a wind wheel 52 connected to the motor 51. The opening of the reinforcement groove 24 and the fan 50 are located on the same side of the motor frame 20, that is, the opening of the reinforcement groove 24 is arranged toward the wind wheel 52. The wind wheel 52 is configured as an axial flow wind wheel 52. Due to the structure of the wind wheel 52, the tip of the wind wheel 52 is closer to one end of the edge of the reinforcement groove 24 close to the air outlet 12, and the airflow at the tip of the blade has a higher flow rate. Therefore, the high-speed airflow rushes into the fan 50. When the end of the reinforcement groove 24 near the edge of the air outlet 12 is hit, it is easy to cause pressure pulsation, which in turn forms an airflow vortex and generates backflow and noise generated by the flow along the reinforcement groove 24. Therefore, at least one end of the reinforcement groove 24 near the edge of the air outlet 12 is adapted to be filled with a filling piece 30, that is, the filling piece 30 is embedded in the reinforcement groove 24, which can effectively cut off the path of the airflow flowing back into the shell 10 along the reinforcement groove 24, increase the amount of air delivered outward, and at the same time, reduce the noise generated when the airflow flows along the reinforcement groove 24, effectively improving the sound quality of the air supply. It can also enhance the connection strength between the adapter leg 22 and the front panel 11 to a certain extent. Of course, in other embodiments, without considering factors such as cost, the filling piece 30 can also fill other reinforcement grooves 24 except the reinforcement groove 24 near the edge of the air outlet 12, which can improve the structural strength of the reinforcement groove 24.

[0048] Furthermore, the minimum distance between the side of the filling piece 30 away from the adapter leg 22 and the wind wheel 52 is h, 5mm≤h≤10mm, and the minimum distance is specifically the distance between the filling piece 30 and the blade tip of the wind wheel 52. By limiting the minimum distance between the filling piece 30 and the blade tip of the wind wheel 52 to between 5mm and 10mm, such a setting can ensure that the filling piece 30 fills the reinforcement groove 24 near the edge of the air outlet 12, thereby improving the air supply and noise of the air conditioner, and can also ensure that there is a certain distance between the filling piece 30 and the blade tip of the wind wheel 52, so as to reduce the possibility of interference between the filling piece 30 and the wind wheel 52 and improve the rotation reliability of the wind wheel 52.

[0049] Specifically, when h is less than 5 mm, the distance between the filler 30 and the blade tip of the wind wheel 52 is small, which is not conducive to eliminating the noise of the airflow flowing through the enhancement slot 24 when the fan 50 rotates at a high speed. When h is greater than 10 mm, the distance between the filler 30 and the blade tip of the wind wheel 52 is large, which tends to increase the space occupied by the fan 50 and the front panel 11, which is not conducive to the miniaturization of the air conditioner. Therefore, the minimum distance between the filler 30 and the blade tip of the wind wheel 52 is limited to between 5 mm and 10 mm, and its specific values ​​include but are not limited to 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm. However, in other embodiments, if the corresponding requirements are met, the minimum distance between the filler 30 and the blade tip of the wind wheel 52 can be greater than 10 mm, or less than 5 mm.

[0050] On this basis, the minimum height of the filling piece 30 may be no less than the maximum depth of the reinforcement groove 24 , which helps to completely fill the filling piece 30 .

[0051] See also Figures 3 to 4 In an embodiment of the present invention, the filling gap between the filling piece 30 and the groove side wall of the reinforcement groove 24 is d, 0.1mm≤d≤0.2mm; it can be understood that when d<0.1mm, the filling gap between the filling piece 30 and the groove side wall of the reinforcement groove 24 is small, which easily increases the difficulty of filling the filling piece 30; when d>0.2mm, the filling gap between the filling piece 30 and the groove side wall of the reinforcement groove 24 is large, which easily forms a new air flow gap between the filling piece 30 and the groove side wall of the reinforcement groove 24, thereby affecting the air supply volume of the air conditioner and generating noise. Therefore, limiting the filling gap between the filling piece 30 and the groove side wall of the reinforcement groove 24 to between 0.1mm and 0.2mm can not only reduce the filling difficulty of the filling piece 30 and improve the assembly efficiency of the filling piece 30 and the motor frame 20, but also ensure the filling effect of the filling piece 30, increase the air supply volume blown out of the air outlet 12 of the air conditioner, and reduce the noise during the operation of the air conditioner.

[0052] Specifically, the specific value of the filling gap between the filling piece 30 and the groove side wall of the reinforcement groove 24 includes but is not limited to 0.1mm, 0.12mm, 0.14mm, 0.15mm, 0.16mm, 0.18mm, and 0.2mm.

[0053] See also Figures 3 to 4 In an embodiment of the present utility model, the adapter leg 22 includes a first section 221 and a second section 222 connected to each other, the first section 221 is connected to the fixing seat 21, one end of the second section 222 is connected to the first section 221, and the other end is connected to the front panel 11, at least part of the reinforcement groove 24 is formed in the second section 222, and the filling member 30 is at least provided in the reinforcement groove 24 of the second section 222. It can be understood that the reinforcement groove 24 is formed in the second section 222, which can effectively strengthen the structural strength of the second section 222 and at the same time improve the connection between the adapter leg 22 and the front panel 11. Connection reliability; and, the reinforcing groove 24 of the second section 222 is filled with a filling piece 30. At this time, the filling piece 30 is adapted to the filling groove of the second section 222, which helps to further improve the structural strength of the second section 222 and the connection reliability with the front panel 11. Then, when the high-speed airflow hits the second section 222, the second section 222 can reliably withstand the impact of the airflow, and at the same time use the filled filling piece 30 to block the flow of the airflow in the reinforcing groove 24, thereby reducing the leakage of the airflow at the second section 222, increasing the air supply at the air outlet 12, and reducing the noise at the second section 222.

[0054] Specifically, in the embodiment of the present invention, the second section 222 is configured to gradually expand toward the front panel 11. This configuration can increase the effective connection area between the adapter leg 22 and the front panel 11, thereby improving the connection strength and reliability between the adapter leg 22 and the front panel 11. The second section 222 is configured to gradually expand relative to the first section 221, meaning that at least a portion of the first section 221 has the same width as the smaller diameter section of the second section 222, which can reduce the overall weight of the adapter leg 22 to a certain extent. When the filler 30 fills the second section 222, the filler 30 also gradually expands toward the front panel 11.

[0055] Specifically, in an embodiment of the present invention, the second section 222 is tilted in a direction away from the fan 50. It is understandable that the extension direction of the second section 222 intersects the plane of the air outlet 12. In this case, the extension direction of the first section 221 can be parallel to the radial direction of the air outlet 12. The first section 221 and the second section 222 are arranged at an angle, which allows the motor frame 20 to protrude in front of the air outlet 12, thereby increasing the assembly space within the housing 10, making it easier for the fan 50 to be accommodated in the assembly space and connected to the motor frame 20. When the filler 30 is filled to the second section 222, the filler 30 is also tilted in a direction away from the fan 50.

[0056] In addition, after the fan 50 is installed on the motor frame 20, since the motor frame 20 protrudes from the air outlet 12 of the front panel 11, it can ensure that the stress between the front panel 11, the second section 222, and the first section 221 is not too large, which can improve the structural stability of the adapter leg 22 itself and the connection stability between the adapter leg 22 and the front panel 11 to a certain extent. In this way, the supporting stability of the motor frame 20 for the fan 50 can be improved.

[0057] See also Figures 6 to 7 In an embodiment of the present invention, a weight-reducing groove 31 opening toward the adapter leg 22 is provided on the filling piece 30. Such a configuration can reduce the weight of the filling piece 30 while ensuring the filling effect of the filling piece 30 on the reinforcement groove 24, and can effectively save costs. At the same time, the adapter leg 22 is used to block the notch of the weight-reducing groove 31 to avoid noise generated by airflow flowing in the weight-reducing groove 31.

[0058] Among them, the wall thickness of the weight-reducing groove 31 is k, 1mm≤k≤2mm. Such a setting can not only improve the structural stability of the filling piece 30, reduce the risk of deformation caused by airflow impact and collision with the adapter leg 22 during the filling process, and improve the filling effect of the filling piece 30, thereby ensuring the air supply volume and low noise of the air conditioner, but also can make the filling piece 30 with less material, thereby reducing the weight of the filling piece 30.

[0059] Specifically, when k is less than 1 mm, the wall thickness of the weight-reducing groove 31 is relatively small. This is not conducive to the stability of the filler 30 when the airflow impacts the filler 30 at a high speed of the fan 50, and it is prone to deformation. When k is greater than 2 mm, the wall thickness of the weight-reducing groove 31 is relatively large, which tends to increase the weight of the filler 30 and is not conducive to lightweighting the filler 30. Therefore, the wall thickness of the weight-reducing groove 31 is limited to between 1 mm and 2 mm, and its specific values ​​include but are not limited to 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, and 2 mm. However, in other embodiments, the wall thickness of the weight-reducing groove 31 may be greater than 2 mm, or less than 1 mm, if the corresponding requirements are met.

[0060] See also Figure 5 In an embodiment of the present invention, the air conditioner further includes an air guide ring 40 connected to the front panel 11. The filler 30 is connected to the inner side of the air guide ring 40. This facilitates the simultaneous filling of the filler 30 into the reinforcement groove 24 when the air guide ring 40 is connected to the front panel 11, thereby simplifying the overall assembly process. The connection methods between the air guide ring 40 and the front panel 11 include, but are not limited to, screw connection, snap-on crimping, and latch connection.

[0061] Optionally, in an embodiment of the present invention, the filler 30 is integrally provided with the air guide ring 40 and can be integrally formed by stamping to ensure processing efficiency and quality of the air guide ring 40 and the filler 30. Alternatively, the filler 30 can be fixed into a single body by bonding, riveting, or the like. Furthermore, the integrated body of the air guide ring 40 and the filler 30 can be quickly assembled to the front panel 11, and the filler 30 can be filled into the reinforcement groove 24, thereby improving overall assembly efficiency. Of course, in other embodiments, the filler 30 can also be integrally formed by casting or injection molding.

[0062] Specifically, in an embodiment of the present invention, a connection seat 42 is provided on the outside of the air guide ring 40. The connection seat 42 and the front panel 11 are provided with connection holes corresponding to each other, for jointly allowing a fastener to penetrate and lock. The fastener can be a screw. At least one of the connection hole and the two connection holes on the front panel 11 is a threaded hole, or a nut threadedly connected to the screw is configured to ensure that the fastener firmly connects the air guide ring 40 and the front panel 11. Among them, multiple connection seats 42 are evenly spaced along the outside of the air guide ring 40 to improve the connection strength between the air guide ring 40 and the front panel 11, and at the same time, ensure that the air guide ring 40 and the front panel 11 are evenly stressed.

[0063] See also Figures 2 to 4In an embodiment of the present invention, the outer contour of the adapter leg 22 is provided with a flange 23 extending toward the fan 50 to form the reinforcement groove 24 with the adapter leg 22. Multiple flanges 23 may be provided, extending along the outer contour of the motor frame 20. Furthermore, the adapter leg 22 and the two flanges 23 provided on either side of the adapter leg 22 form a reinforcement groove 24 opening toward the wind wheel 52, thereby enhancing the structural strength of the motor frame 20 and ensuring reliable support of the fan 50 by the motor frame 20. Furthermore, the adapter leg 22 may also be provided with a reinforcement groove extending along its extension direction, which is the radial direction of the air outlet 12, to further enhance the structural strength of the adapter leg 22.

[0064] See also Figure 5 In the embodiment of the present utility model, a positioning notch 41 is provided on the air guide ring 40. The positioning notch 41 is located on the side of the filling piece 30 and is used for inserting the flange 23. It can be understood that positioning notches 41 are formed on both sides of the filling piece 30. The positioning notches 41 are provided corresponding to the flange 23. However, when the air guide ring 40 is fixed to the front panel 11, the flange 23 close to the edge of the air outlet 12 is inserted into the corresponding positioning notch 41, which can make the air guide ring 40 as close to the air outlet 12 as possible and ensure The air flow is ensured to flow toward the air outlet 12 under the guiding action of the air guide ring 40 without being blocked by the front panel 11, thereby reducing the flow resistance and improving the efficiency of the fan 50. At the same time, the noise generated by the air flow impacting the front panel 11 is reduced. The air guide ring 40 can also be positioned to improve the alignment efficiency of the connecting seat 42 and the corresponding connecting holes of the front panel 11, thereby improving the installation efficiency of the air guide ring 40 and the front panel 11. The connection area between the air guide ring 40 and the front panel 11 can also be increased to improve the connection reliability of the air guide ring 40.

[0065] Optionally, in an embodiment of the present invention, the air conditioner includes an indoor unit and an outdoor unit connected to the indoor unit, and the outdoor unit includes the housing 10. It is understandable that when the air conditioner is configured as a split-type air conditioner, the air conditioner includes an indoor unit and an outdoor unit connected to the indoor unit, and the housing 10 can be the housing 10 of the outdoor unit. Furthermore, combined with all the beneficial effects brought about by the technical solutions of the above embodiments, the air supply volume of the outdoor unit can be effectively increased while reducing the noise during operation of the outdoor unit. Of course, in other embodiments, the indoor unit includes the housing 10. Similarly, the air supply volume of the indoor unit can be effectively increased while reducing the noise during operation of the indoor unit. Alternatively, the air conditioner can also be configured as an integrated air conditioner, such as a window air conditioner. In this case, the front panel 11 of the housing 10 can be located on the side of the window air conditioner close to the outdoors.
