Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an outdoor unit of an air conditioner and an air conditioner. Background Art

[0002] For an air-cooled unit of an air conditioner, in practical applications, the motor of the outdoor unit often encounters various reasons that cause the motor to be overloaded or blocked during operation, resulting in the problem of the motor winding being burned out.

[0003] During the application of the air-cooled unit, the outdoor unit is usually installed on the roof or other places. In order to prevent foreign objects from entering the interior of the outdoor unit, an air inlet and outlet grille is usually provided around the fan blade to provide a certain degree of protection against the entry of foreign objects. However, with the long-term use of the outdoor unit, it is still inevitable that dust or foreign objects will enter the interior of the outdoor unit, causing the heat dissipation grille to be blocked and the motor to malfunction.

[0004] This hard connection method between the motor and the fan blade is likely to burn out the motor when the fan blade is blocked. Therefore, an indirect method is usually used to protect the motor against overload or blockage. For example, a temperature switch is usually used for over-temperature protection in an AC motor. Once the motor is in an overloaded or blocked state, the motor winding quickly heats up, the temperature switch disconnects, and the motor stops running until the fault is restored. For a DC motor, protection is generally provided by controlling the current sampling or temperature sensor to provide the motor signal input. However, this method requires complex hardware circuits and software designs to implement, and there are also certain failure rates in the software and hardware of the load itself. Therefore, there is also a certain proportion of motor burnout failure phenomena in DC motors.

[0005] A dust-proof device for a self-cleaning outdoor unit of an air conditioner is disclosed in the prior art, which relates to the technical field of air conditioner dust prevention. By comparison, this solution is a pure mechanical drive device, which cannot achieve intelligent control of dust prevention and cleaning, lacks a suitable feedback mechanism, has low efficiency, and cannot truly solve the problem of the motor winding being burned out due to overload and blockage.

[0059] The following will be combined with Figures 1 to 4 to elaborate on the technical solutions provided by the present utility model in more detail.

[0060] The present utility model provides an outdoor air conditioner, which includes a main housing body 10.

The outer magnetic rotor 23 is connected to the output shaft of the air-cooled motor 22, and the inner magnetic rotor 24 is magnetically coupled to the outer magnetic rotor 23;

[0062] The fan blade 26 is arranged on a rotating shaft 27, the rotating shaft 27 is connected to the inner magnetic rotor 24, and the air-cooled motor 22 drives the outer magnetic rotor 23 to rotate, driving the inner magnetic rotor 24 and the fan blade 26 to rotate.

[0064] In addition, the air-cooled unit 11 includes an air-cooled motor 22, an outer magnetic rotor 23, an inner magnetic rotor 24 and a fan blade 26.

[0065] It can be understood that the air-cooled unit 11 adopts magnetic coupling connection between the outer magnetic rotor 23 and the inner magnetic rotor 24, and magnetic transmission between the outer magnetic rotor 23 and the inner magnetic rotor 24, thus avoiding the rigid connection between the output shaft of the air-cooled motor 22 and the fan blade 26; the function of the dust-proof component 13 is to prevent foreign objects entering the heat dissipation grille from entering the air-cooled unit 11, thus causing the problem of winding burnout of the air-cooled motor 22.

[0066] It should be noted that the dust-proof component 13 can be a dust-proof net 14 or other dust-proof structures with dust-proof effects.

The isolation cover 25 is disposed between the inner magnetic rotor 24 and the outer magnetic rotor 23. The isolation cover 25 can prevent foreign objects from entering between the inner magnetic rotor 24 and the outer magnetic rotor 23, thereby effectively avoiding the presence of foreign objects between the inner magnetic rotor 24 and the outer magnetic rotor 23, which may affect the operation of the air-cooled unit 11 and ensure the normal operation of the air-cooled unit 11.

[0069] In addition, the isolation cover 25 can effectively isolate the inner magnetic rotor 24 and the outer magnetic rotor 23, prevent the inner magnetic rotor 24 and the outer magnetic rotor 23 from contacting each other, and effectively ensure the normal operation of the air-cooled unit 11.

[0070] In some embodiments of the present utility model, the isolation cover 25 includes a first cover body 28 and a second cover body 29. The first cover body 28 is connected to the air-cooled motor 22. The second cover body 29 is disposed between the inner magnetic rotor 24 and the outer magnetic rotor 23. The first cover body 28 is connected to the second cover body 29 to wrap the output shaft of the air-cooled motor 22 and the outer magnetic rotor 23.

[0071] In some of the above embodiments of the present utility model, the isolation cover 25 includes a first cover body 28 and a second cover body 29. The first cover body 28 and the second cover body 29 wrap the output shaft of the air-cooled motor 22 and the outer magnetic rotor 23, thereby effectively blocking foreign objects and preventing foreign objects from entering the connection between the air-cooled motor 22 and the outer magnetic rotor 23, ensuring the operation of the motor. The second cover body 29 is disposed between the inner magnetic rotor 24 and the outer magnetic rotor 23, which can effectively prevent the inner magnetic rotor 24 and the outer magnetic rotor 23 from contacting each other.

[0072] It can be understood that the first cover body 28 and the second cover body 29 are detachably connected. For example, the outer shell of the air-cooled motor 22 is usually a cylindrical structure. The first cover body 28 and the second cover body 29 can both be hollow cylindrical structures, and the first cover body 28 and the second cover body 29 are connected by a detachable structure, so as to ensure that the first cover body 28 and the second cover body 29 can prevent the inner magnetic rotor 24 and the outer magnetic rotor 23 from contacting each other, and can effectively prevent foreign objects from entering the air-cooled motor 22 and avoid the air-cooled motor 22 from being burned out.

[0075] Both ends of the dust-proof net 14 are respectively wound around two winding shafts 17, so that the dust-proof net 14 is placed between the air-cooled unit 11 and the heat sink 12, and the two winding drive structures 16 can drive the dust-proof net 14 to wind around the two winding shafts 17;

[0076] The cleaning component is used to clean the dust-proof net 14 when the dust-proof net 14 is wound between the two winding shafts 17.

[0077] In some of the above embodiments of the present invention, the dust-proof component 13 includes a dust-proof net 14, a cleaning component and a winding component. The dust-proof net 14 is wound around the winding shafts 17 of the two winding components, and the dust-proof net 14 can be wound and unwound under the cooperation of the two winding shafts 17. During the winding and unwinding process of the dust-proof net 14, the cleaning component can clean the dust-proof net 14, thereby cleaning the dust or foreign objects on the dust-proof net 14, effectively protecting the heat sink 12 and the air-cooled unit 11.

[0078] In some embodiments of the present invention, the cleaning component is a cleaning brush 15. The cleaning brush 15 can clean the foreign objects on the dust-proof net 14 during the winding and unwinding process of the dust-proof net 14. Specifically, the cleaning brush 15 can be arranged to be in contact with the dust-proof net 14. When the dust-proof net 14 moves, the cleaning brush 15 can brush off the foreign objects on the dust-proof net 14 to complete the cleaning.

[0081] It can be understood that the first gear 20 and the second gear 21 are meshed, and the rotation directions of the rolling shaft 19 and the winding shaft 17 are opposite, which makes the rotation direction of the cleaning brush 15 opposite to the moving direction of the dust-proof net 14, so as to be able to clean the dust-proof net 14 more effectively; of course, in some embodiments, the rotation directions of the rolling shaft 19 and the winding shaft 17 can also be the same, and the cleaning effect of the dust-proof net 14 can also be achieved.

[0083] In some of the above embodiments of the present utility model, the dust-proof component 13 further includes a box body 32.

After the cleaning brush 15 cleans the dust-proof net 14, dust or foreign objects are directly discharged from the funnel-shaped discharge port 33 of the box body 32, thereby preventing foreign objects from entering the air-cooled unit 11 and effectively isolating dust or foreign objects.

[0084] It can be understood that the winding shaft 17 and the rolling shaft 19 are rotatably arranged in the box body 32, which can be specifically realized by bearings. A grid plate 34 is arranged at the bottom inside the box body 32. The bottoms of the winding shaft 17 and the rolling shaft 19 are rotatably arranged on the grid plate 34. The foreign objects after being cleaned by the cleaning brush 15 can pass through the grid plate 34 and be discharged to the discharge port 33, and the grid plate 34 can effectively prevent external foreign objects from entering the box body 32. And a through hole for the dust-proof net 14 to pass through is arranged on the box body 32.

The plurality of guide shafts 18 are rotatably arranged in the machine shell main body 10. The dust-proof net 14 between the two groups of winding shafts 17 is sequentially wound around the plurality of guide shafts 18.

[0086] In some of the above embodiments of the present utility model, a plurality of guide shafts 18 are further included. The guide shafts 18 are used to play a guiding role to ensure that the dust-proof net 14 can be smoothly wound up, and the dust-proof net 14 can be set at a specified position through the guide shafts 18, so as to facilitate the dust-proof net 14 to effectively prevent dust.
