[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0033] In order to solve the technical problem of low safety in the use of motors in the sweeping mechanism in related technologies, the present invention provides a sweeping mechanism and an air conditioner having the same.

[0034] like Figures 1 to 11 As shown, the air-sweeping mechanism includes: a housing 1, which has an air outlet 11 and a through hole 12 located on one side of the air outlet 11; an air-sweeping blade 2, which is disposed at the air outlet 11 and located on one side of the through hole 12, and includes blades 21 capable of sweeping left and right; a motor base 7, which is located on the other side of the through hole 12, and the surface of the motor base 7 opposite to the through hole 12 forms a windproof surface 71; a motor 5, which is mounted on the motor base 7 and located on the side of the windproof surface 71 away from the through hole 12; and a transmission assembly, which passes through the through hole 12 and is connected to the output shaft of the motor and the blades 21. When the motor 5 drives the blades 21 to sweep left and right through the transmission assembly, the air blows through the through hole 12 in the left and right direction toward the windproof surface 71 of the motor base 7, so as to avoid the air blowing directly onto the motor 5.

[0035] This application optimizes the structure of the air-sweeping mechanism to prevent direct airflow from blowing onto the motor 5, thereby improving the safety of the motor and, consequently, the safety of the air-sweeping mechanism.

[0036] Optionally, the opening of the motor mount 7 is perpendicular to the through hole 12. This prevents air blowing towards the motor mount 7 through the through hole 12 from blowing directly onto the motor 5 installed inside the motor mount 7 through the opening of the motor mount 7.

[0037] Optionally, the height of the windproof surface 71 is greater than the height of the motor 5, and the width of the windproof surface 71 is greater than the width of the motor 5. In this way, the area of ​​the windproof surface 71 is large enough to prevent the motor 5 from being exposed outside the windproof surface 71, thereby improving the windproof effect of the windproof surface 71 and preventing the motor 5 from being directly blown by the wind.

[0038] Optionally, the windproof surface 71 has no openings to prevent wind from blowing directly onto the motor 5.

[0039] like Figure 2As shown, optionally, the wiring terminal 51 of the motor 5 is mounted on the motor base 7 with the wiring terminal 51 facing upwards; the motor base 7 has a first opening 72 on its upper part that mates with the wiring terminal 51. In this way, the opening direction of the first opening 72 avoids the windproof surface 71, thereby preventing wind from blowing directly on the motor 5.

[0040] like Figure 2 As shown, optionally, the wiring terminal 51 of the motor 5 is located at the first opening 72 and is inclined towards the side away from the through hole 12. In this way, the wiring terminal 51 is furthest away from the through hole 12, which improves the service life of the motor and facilitates the connection between the wiring terminal 51 and the motherboard, making wiring more convenient.

[0041] Optionally, the output shaft 52 of the motor 5 is mounted on the motor mount 7 facing forward; the front of the motor mount 7 is provided with a second opening 73 that mates with the output shaft 52. In this way, the opening direction of the second opening 73 avoids the windproof surface 71, thereby preventing wind from blowing directly on the motor 5.

[0042] Optionally, the transmission assembly includes a sweeping connecting rod 3 and a crank 4. One end of the crank 4 is connected to the output shaft 52 of the motor 5. The sweeping connecting rod 3 passes through the through hole 12, with one end of the sweeping connecting rod 3 connected to the other end of the crank 4, and the other end of the sweeping connecting rod 3 connected to the blade 21. In this way, the blade 21 is driven to sweep left and right using the sweeping connecting rod 3 and the crank 4, resulting in a simple structure and smooth and reliable movement.

[0043] like Figure 2 As shown, optionally, the crank 4 is located in front of the motor base 7 and connected to the output shaft 52; the motor base 7 has a limiting structure 74, which is located on the side of the second opening 73 near the through hole 12, and is used to limit the crank 4. In this way, by limiting the crank 4, the left and right sweeping of the blade 21 is limited, ensuring the stability of the left and right sweeping.

[0044] like Figure 11 As shown, optionally, the inner surface of the motor base 7 is provided with a protruding structure 75; such as Figure 9 As shown, the housing of the motor 5 has a stop surface 53 that mates with the protruding structure 75; when the motor 5 is mounted on the motor base 7, the stop surface 53 abuts against the protruding structure 75. In this way, the position of the motor 5 within the motor base 7 is quickly positioned by the cooperation of the protruding structure 75 and the stop surface 53, making it convenient to quickly mount the motor 5 onto the motor base 7.

[0045] Optionally, such as Figure 10 and Figure 11 As shown, the inner surface of the bottom of the motor base 7 is provided with ribs 76, which are used to abut against the motor 5. In this way, the motor 5 can be prevented from contacting the entire inner surface of the motor base 7.

[0046] Optionally, the surface of the motor mount 7 near the housing 1 has an assembly gap with the housing 1 to avoid resonance between the motor 5 located on the motor mount 7 and the housing 1, further improving the operational stability of the sweeping mechanism and avoiding noise generation.

[0047] Optionally, the motor mount 7 has a first connecting hole 77; the housing of the motor 5 has a second connecting hole 54 that mates with the connecting hole; the sweeping mechanism also includes a first screw 6, which passes through the second connecting hole 54 and is threaded into the first connecting hole 77. Thus, the motor 5 can be mounted on the motor mount 7 using the first screw 6.

[0048] In such Figure 2 In the specific embodiment shown, only one first screw 6 is provided. The motor 5 is installed on the motor base 7 by the first screw 6, which helps to improve the assembly efficiency of the sweeping mechanism and reduce the cost of the sweeping mechanism.

[0049] In an alternative embodiment not shown in this application, the number of first screws 6 may also be multiple, thereby improving the assembly stability between the motor 5 and the motor base 7.

[0050] Optionally, the first screw 6 is a self-tapping screw.

[0051] like Figures 2 to 4 As shown, optionally, the motor base 7 is provided with a first mounting hole 78, and the housing 1 has a second mounting hole 13 that mates with the first mounting hole 78; the air-sweeping mechanism also includes a second screw 8, which passes through the first mounting hole 78 and is threaded into the second mounting hole 13. In this way, the motor base 7 can be mounted on the housing 1 by means of the second screw 8.

[0052] Optionally, the second screw 8 is a self-tapping screw.

[0053] Optionally, to improve the assembly stability between the motor mount 7 and the housing 1, multiple second screws 8 can be provided.

[0054] In such Figure 2 In the specific embodiment shown, two second screws 8 are provided, located on the left and right sides of the motor base 7 respectively, to balance the cost of the air sweeping mechanism and the assembly stability between the motor base 7 and the housing 1.

[0055] like Figures 2 to 4 As shown, optionally, the motor base 7 has a positioning hole 79, and the housing 1 is provided with a positioning post 14 that mates with the positioning hole 79. In this way, the positioning hole 79 and the positioning post 14 can be used to achieve rapid positioning of the motor base 7, thereby improving the assembly efficiency of the air sweeping mechanism.

[0056] In such Figure 2In the specific embodiment shown, the motor base 7 is first placed on the housing 1 using the positioning hole 79 and the positioning post 14, and then the motor base 7 is fixed to the housing 1 using the second screw 8. In this embodiment, the air sweeping mechanism is simple to assemble and highly efficient, and the position of the motor base 7 is stable, ensuring the relative position of its windproof surface 71 and the through hole 12, thus preventing the wind from blowing directly on the motor 5.

[0057] like Figure 5 and Figure 7 As shown, the transmission assembly includes: a crank 4, one end of which is connected to the output shaft 52 of the motor 5; and a sweeping connecting rod 3, which passes through the through hole 12, one end of which is connected to the other end of the crank 4, and the other end of which is connected to the blade 21. Thus, the blade 21 is driven to sweep left and right using the sweeping connecting rod 3 and the crank 4, resulting in a simple structure and smooth, reliable operation.

[0058] In an alternative embodiment not shown in this application, the transmission component may adopt other structures, as long as it can drive the blades 21 to sweep air from side to side.

[0059] like Figure 7 and Figure 8 As shown, optionally, one end of the swing connecting rod 3 has two oppositely arranged snap-fit ​​connectors 31, and the crank 4 has snap-fit ​​holes 41 that mate with the two snap-fit ​​connectors 31. This facilitates the assembly of the swing connecting rod 3 and the crank 4; simply insert the two snap-fit ​​connectors 31 into the snap-fit ​​holes 41 to achieve a snap-fit ​​engagement. The swing connecting rod 3 and the crank 4 can rotate relative to each other, while ensuring that the two parts are assembled in place without the risk of falling off.

[0060] like Figure 5 and Figure 6 As shown, optionally, the sweeping blade 2 includes a plurality of blades 21 spaced apart along its length, each blade 21 having a connecting shaft 211. The sweeping connecting rod 3 has a plurality of shaft holes 32 along its length, each shaft hole 32 corresponding to a plurality of connecting shafts 211, with the connecting shafts 211 fitting into the shaft holes 32. This utilizes the shaft hole fit to connect the sweeping blade 2 to the plurality of blades 21, ensuring that the rotation directions of the two parts are consistent, and the sweeping connecting rod 3 can drive the plurality of blades 21 to sweep left and right.

[0061] This application also provides an air conditioner, including the above-mentioned and below-mentioned air sweeping mechanism, which guides airflow in the air conditioner and increases the air sweeping area.

[0062] When the air-sweeping mechanism provided in this application is applied in an air conditioner, the motor of the air-sweeping mechanism has a long service life and high safety, thereby reducing the frequency of motor replacement and maintenance, thus improving the safety of the air conditioner, enhancing its air-sweeping performance, and improving the user experience.

[0063] Optionally, motor 5 is a stepper motor.

[0064] Optionally, the housing 1 includes a bottom shell, and the air outlet 11 is disposed on the bottom shell. When the air conditioner is in operation, the air outlet 11 of the housing 1 delivers air, and the stepper motor drives the air sweeping mechanism to start operating. The air from the air outlet 11 passes through the through hole 12 on the right side of the bottom shell and blows towards the motor mount 7 in the air sweeping mechanism. The designed motor mount 7, after being assembled with the stepper motor 5, has an opening direction perpendicular to the direction of the through hole 12, which can directly block the air outlet, effectively preventing the air outlet from blowing directly onto the stepper motor, ensuring the overall sealing effect, isolating the cold air of the prototype, avoiding the stepper motor from becoming damp and affecting its reliability, and also effectively isolating the stepper motor from resonance interference. This ensures that there is no obvious water accumulation or water droplets in the bearings and other internal parts of the stepper motor, and that the bearings operate smoothly and without obstruction, achieving a better overall sealing and dustproof effect.

[0065] Optionally, the air conditioner is a wall-mounted air conditioner, and the air-sweeping mechanism is installed in the wall-mounted unit of the wall-mounted air conditioner.

[0066] The stepper motor in the swing mechanism of the wall-mounted air conditioner has the potential for leakage and short circuit when used in humid environments. When the wall-mounted air conditioner is turned on for a long time, the airflow from the air outlet blows directly on the stepper motor for a long time, causing water droplets to appear on the surface of the stepper motor or around the plug, which reduces the safety of the motor and affects the left and right swing performance of the air conditioner and the user experience.

[0067] The air-sweeping structure provided in this application can greatly improve the safety of motor use, effectively solve the problem of water accumulation on the motor surface in humid experiments, improve the stability of the left and right air-sweeping mechanisms, reduce the risk of electrical safety hazards caused by airflow directly blowing on the stepper motor from the air outlet, and enhance customer experience and satisfaction.

[0068] In application Figures 1 to 11In a specific embodiment, a drive device for the sweeping mechanism is designed on the right side of the air outlet 11. This drive device includes a sweeping connecting rod 3, a crank 4, a motor 5, and a motor base 7. A through hole 12 is designed on the right side of the air outlet of the bottom shell for the sweeping connecting rod 3 to pass through. The mushroom head formed by the two snap joints of the sweeping connecting rod 3 cooperates with the crank 4. The crank 4 cooperates with the output shaft of the motor 5. The motor base 7 is designed to cooperate with the bottom shell screws. The motor 5 is screwed into the motor base 7, and the wiring terminal 51 of the motor 5 faces upward. The opening direction of the designed motor base 7 is the same as the direction of the wiring terminal 51 of the motor 5, and is perpendicular to the through hole 12. The designed motor base 7 has a crank limiter, which effectively increases the left and right sweeping range. When the air conditioner is in the on state, the air outlet through the through hole 12 will not blow directly onto the motor 5, and water will not accumulate on the surface of the motor 5, effectively improving the safety of motor use. The motor base 7 is fixed to the bottom of the bottom shell, and the assembly is effectively improved by synchronously fixing it with the positioning post 14 through the second screw 8. Meanwhile, sufficient clearance between the bottom of the motor mount and the base shell minimizes base shell resonance during stepper motor operation. The stepper motor is installed inside the motor mount, and the stepper motor and motor mount are fixed together with a single screw, with the stepper motor's connector 51 facing outwards. To match the corresponding position of the stepper motor's connector 51, the opening direction of the motor mount 7 after assembly with the base shell also faces outwards, creating consistency. The outward-facing connector 51 of the stepper motor ensures easier wiring between the stepper motor and the motherboard, and also ensures the maximum distance between the connector and the through hole 12, extending the lifespan of the stepper motor. To ensure the stepper motor is properly assembled and does not move within the motor mount 7, the motor mount 7 is designed with a raised structure 75 and ribs 76, which, together with the first screw 6, fix the motor 5, ensuring a sealing effect and preventing water from flowing into the motor mount 7. Additionally, a limiting structure 74 is designed on the motor mount 7 to ensure the stability of left and right sweeping. The output shaft 52 of motor 5 mates with the large end shaft hole of crank 4 and is fixed by screws and keyways, ensuring the relative stability between the two parts. The small end of crank 4 mates with the mushroom head shaft hole of the sweeping connecting rod 3, ensuring that the two parts are properly assembled without the risk of falling off. The sweeping connecting rod 3 and the sweeping blade 2 mate through shaft holes, ensuring the consistency of their rotation directions. The sweeping blade 2 is mounted on the bottom shell. The continuous movement of the sweeping mechanism is enhanced through assembly methods such as shaft hole assembly and screw fixing between parts, achieving a left and right sweeping display effect and improving assembly efficiency.When the air conditioner is running, air is supplied through the air outlet 11. The stepper motor drives the air sweeping mechanism to start operating. The air from the air outlet 11 passes through the through hole 12 on the right side of the bottom shell and blows towards the motor mount 7 in the air sweeping mechanism. The design of the motor mount 7, after assembly with the motor 5, is perpendicular to the direction of the through hole 12 on the bottom shell, which can directly block the airflow, effectively preventing the airflow from blowing directly onto the stepper motor, ensuring the overall sealing effect, isolating the prototype from cold air, avoiding moisture in the stepper motor and affecting its reliability, and effectively isolating the stepper motor from resonance interference. This ensures that there is no obvious water accumulation or water droplets in the bearings and other internal parts, and that the bearings operate smoothly and without obstruction. Overall, it achieves a better sealing and dustproof effect.

[0069] The realization of the moisture-proof sweeping mechanism in this application mainly involves innovations in component assembly and structure. Firstly, it addresses assembly solutions for screws, shaft holes, etc.: including the assembly of the motor mount and stepper motor, the stepper motor and crank, and the crank and sweeping connecting rod, to achieve effective assembly and continuous movement of the various components of the sweeping mechanism. Secondly, it provides an overall sealed moisture-proof solution, including the overall structural form and a design to prevent the air outlet from directly blowing air from the stepper motor.
