The wind wheel assembly includes a wind wheel seat and wind wheel blades spaced around the wind wheel seat. A first bearing seat is provided in the stator assembly, and the stator assembly is sleeved on the motor shaft through the first bearing seat. A retaining spring is fixed on the end of the motor shaft passing through the stator assembly, and the stator assembly is fixed to the motor shaft by using the retaining spring. When the stator assembly is energized, a rotating magnetic field is generated to drive the magnetic ring to generate a rotational torque, thereby driving the rotor housing, the motor shaft and the wind wheel assembly to rotate, and the stator assembly is relatively stationary through the first bearing seat.

[0005] By adopting the above technical solution, the centrifugal fan is converted from using an inner rotor motor to using an outer rotor motor. The outer rotor motor has a compact structure, occupies less space inside the air conditioner, improves space utilization, and is easy to maintain. The stator assembly and the rotor assembly can be separated by removing the retaining spring, and the internal structure can be repaired, which reduces disassembly time and reduces maintenance and replacement costs.

[0006] Optionally, the outer diameter of the magnetic ring is larger than the inner circumferential wall of the rotor housing, and the outer circumferential wall of the magnetic ring is connected to the inner circumferential wall of the rotor housing through an adhesive and interference fit.

[0009] By adopting the above technical solution, the wind wheel assembly and the rotor housing are connected by injection molding, so that the wind wheel assembly, i.e. the centrifugal wind wheel and the rotor housing are tightly combined to form a whole, effectively reducing the loosening or displacement between the wind wheel seat and the rotor housing, thereby improving the stability and reliability between the outer rotor motor and the centrifugal wind wheel.

[0010] Optionally, the magnetic ring includes a plurality of permanent magnet parts and a plurality of connecting parts, the plurality of permanent magnet parts are arranged at intervals from each other, and the plurality of connecting parts are respectively arranged between adjacent permanent magnet parts to form an annular structure adapted to the inner circumferential wall of the rotor housing; A plurality of positioning grooves are provided on the bottom inner portion of the rotor housing, and a plurality of positioning plugs are provided on the bottom of the connection parts. The plurality of positioning grooves and the plurality of positioning plugs are arranged correspondingly, and the positioning plugs can be inserted into the positioning grooves for positioning connection.

[0011] By adopting the above technical solution, the positioning plug can be inserted into the positioning groove for positioning connection, ensuring the accuracy of the installation position of the magnetic ring in the rotor housing, improving the assembly progress of the motor, and improving the stability of the motor during use. The plug-in setting method does not require complicated alignment and adjustment processes, thereby improving the efficiency of subsequent replacement of magnetic rings.

[0012] Optionally, a plurality of locking members are provided on the wind rotor seat, and the locking members are sequentially passed through the wind rotor seat and the rotor housing and connected to the connecting portion; The outer wall of the wind wheel seat is provided with a plurality of locking grooves facing the magnetic ring along its circumference, and the plurality of locking members are respectively arranged in the locking grooves. A locking channel is provided at the bottom of the locking groove close to one end of the magnetic ring. The locking channel passes through the wind wheel seat and the rotor shell in sequence, and the bottom of the locking channel extends into the connecting part. A connecting rod is provided in the locking member, and the connecting rod passes through the locking groove of the locking member and is inserted into the connecting part through the locking channel. The locking member can clamp and fix the connecting rod, thereby achieving fixed connection between the magnetic ring, the rotor shell and the wind wheel assembly.

[0013] By adopting the above technical solution, a connecting rod is provided, and the magnetic ring, the rotor housing and the wind wheel assembly are fixedly connected by the connecting rod, thereby connecting the magnetic ring, the rotor housing and the wind wheel assembly into a whole, thereby enhancing the connection strength between the magnetic ring, the rotor housing and the wind wheel assembly, and making the rotor assembly more stable during the rotation of the wind wheel assembly.

[0014] Optionally, the outer peripheral wall of the connecting rod is provided with fine threads, thereby increasing the roughness of the connecting rod, thereby increasing the friction between the connecting rod and the locking member.

[0015] By adopting the above technical solution, the connecting rod is finer in thread and the roughness of its outer surface is increased, so that when it is subsequently clamped and fixed by the locking piece, the friction between the two is increased, making the clamping and locking more secure.

[0016] Optionally, the locking member includes a locking seat, a release switch and a clamping claw seat are provided in the locking seat, the clamping claw seat is provided at the bottom of the locking seat, the release switch is provided at the top of the locking seat, the bottom of the release switch is recessed inward to form a limiting portion, and the top of the clamping claw seat is provided in the limiting portion, the connecting rod can pass through the locking seat, the release switch and the clamping claw seat to enter the locking channel, and the release switch and the clamping claw seat can clamp and fix the connecting rod through a clamping action.

[0017] By adopting the above technical solution, when the connecting rod is inserted into the locking seat, and passes through the tension switch and the clamping claw seat in sequence and enters the locking channel, the magnetic ring, the rotor housing and the wind wheel assembly are fixedly connected. Then, the locking switch and the clamping claw seat are used to lock the connecting rod, thereby completing the fixed connection between the magnetic ring, the rotor housing and the wind wheel assembly.

[0018] Optionally, an internal thread is provided on the inner circumference of the locking seat, and an external thread is provided on the outer circumference of the release switch. The release switch is inserted into the top of the locking seat for threaded connection, so that the release switch can be raised and lowered from the top of the locking seat. When the release switch is lowered, the top of the clamping claw seat is pressed against the bottom of the limit part to clamp and lock the connecting rod passing through the two. When the release switch is raised, the top of the clamping claw seat is disengaged from the limit part to unlock the connecting rod passing through the two. The clamping claw seat includes a clamping base, and a plurality of elastic clamping claw blocks are arranged on the circumferential side of the top of the clamping base. The plurality of clamping claw blocks are arranged around the center position of the top of the clamping base as the center of a circle, and the space between the plurality of clamping claw blocks is used for the connection rod to pass through. The top of the clamping base is fixedly set at the bottom of the plurality of clamping claw blocks, and the tops of the plurality of clamping claw blocks are all arranged in a limiting part. When the limiting part is away from the clamping claw block, the tops of the plurality of clamping claw blocks expand outward, and the tops of the clamping claw blocks are always located inside the limiting part.

[0019] By adopting the above technical solution, the internal threads on the inner circumference of the locking seat and the external threads on the outer circumference of the tension switch engage with each other to generate friction and preload, thereby enabling the limiter to lock or unlock the clamping claw seat. At the same time, multiple clamping claw blocks are used to clamp and secure the connecting rod passing through the interior. When the bottom of the limiter at the bottom of the tension switch abuts the tops of the multiple clamping claw blocks, the tops of the multiple clamping claw blocks contract inward to clamp the connecting rod. When the bottom of the limiter at the bottom of the tension switch no longer abuts the tops of the multiple clamping claw blocks, the tops of the multiple clamping claw blocks expand outward to release the connecting rod.

[0020] Optionally, the outer wall of the wind wheel seat is provided with magnetic closing doors that can be matched on both sides of the locking groove. The two closing doors can close the locking groove. The closing doors are arc-shaped and matched with the arc of the outer wall of the wind wheel seat. A closing groove is provided on the outer wall of the wind wheel seat. The closing door can be slidably set in the closing groove. A compression spring is provided in the closing groove. One end of the compression spring is fixedly connected to the inside of the closing groove, and the other end of the compression spring is connected to the end of the closing door. When the two closing doors are matched to close the closing groove, the compression spring remains in a natural state. When the two closing doors are manually opened, the compression spring shrinks and deforms. After the connecting rod is inserted into the locking member, the compression spring automatically resets to push the closing door out of the closing groove to close the locking groove.

[0021] By adopting the above technical solution, the locking slot is opened and closed by using an arc-shaped closing door. When the magnetic ring, the rotor housing and the wind wheel assembly are fixedly connected, the closing door is closed, so that the locking slot is closed. Moreover, since the two closing doors are arc-shaped and match the arc shape of the outer peripheral wall of the wind wheel seat, the wind wheel seat maintains an arc-shaped state when it rotates, thereby reducing air resistance during rotation, reducing energy consumption and improving the rotation efficiency of the rotor assembly.

[0022] In a second aspect, the present application provides a centrifugal wind wheel rotor magnetic disk installation process, which adopts the following technical solutions: A centrifugal wind wheel rotor disk installation process, based on the above-mentioned centrifugal wind wheel rotor disk installation structure, includes the following specific steps: S1. Install the rotor assembly. Apply adhesive to the inner wall of the rotor housing. Then install the magnetic ring on the inner wall of the rotor housing and connect the rotor housing and the magnetic ring with an interference fit. S2. Install the wind wheel assembly, place the inner peripheral wall cover of the wind wheel seat on the outer peripheral wall of the rotor shell, and use an injection molding machine to connect the two by injection molding to form a tight combination.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The centrifugal impeller uses an outer rotor motor instead of an inner rotor motor. The outer rotor motor has a compact structure, occupies less space inside the air conditioner, improves space utilization, and is easy to maintain. The stator assembly and rotor assembly can be separated by removing the retaining ring, and the internal structure can be repaired, which reduces disassembly time and reduces maintenance and replacement costs. 2. The method of directly sticking the magnetic ring to the rotor housing with adhesive is simple to operate and has low cost. After the magnetic ring and the rotor housing are connected by interference fit, the gap between the magnetic ring and the rotor housing is filled with adhesive, making the magnetic ring more stable during rotation and reducing vibration and noise. 3. The internal threads on the inner circumference of the locking seat and the external threads on the outer circumference of the tension switch engage with each other, generating friction and preload, so that the limiter locks or unlocks the clamping claw seat. Simultaneously, multiple clamping claws are used to clamp and secure the connecting rod that passes through the interior. When the bottom of the limiter at the bottom of the tension switch abuts against the tops of the multiple clamping claws, the tops of the multiple clamping claws contract inward to clamp the connecting rod. When the bottom of the limiter at the bottom of the tension switch no longer abuts against the tops of the multiple clamping claws, the tops of the multiple clamping claws expand outward to release the connecting rod. 4. Use the arc-shaped closing door to open and close the locking slot. When the magnetic ring, rotor housing and wind wheel assembly are fixedly connected, the closing door is closed to close the locking slot. Since the two closing doors are arc-shaped, they match the arc shape of the outer peripheral wall of the wind wheel seat, so that when the wind wheel seat rotates, it maintains the arc state, reducing air resistance during rotation, reducing energy consumption, and improving the rotation efficiency of the rotor assembly.

The second bearing seat 33 is arranged below the motor shaft 1, and the stator assembly 3 is sleeved on the motor shaft 1 through the first bearing seat 31 and the second bearing seat 33. The first bearing seat 31 and the second bearing seat 33 arranged at intervals from each other are used to make the concentricity of the stator assembly 3 consistent and its rotation stability is guaranteed. The motor shaft 1 passes through the end of the stator assembly 3 and is fixed with a retaining spring 32. The stator assembly 3 is fixed to the motor shaft 1 by the retaining spring 32. When the stator assembly 3 is energized to generate a rotating magnetic field, the magnetic ring 22 is driven to generate a torque, thereby driving the rotor housing 21, the motor shaft 1 and the wind wheel assembly 4 to rotate, and the stator assembly 3 is relatively stationary through the first bearing seat 31; in this embodiment, the stator assembly 3 includes existing technical structures such as a stator core and a stator winding. The stator core can adopt a twelve-slot ten-pole or twelve-slot fourteen-pole structure. The air gap between the stator assembly 3 and the rotor assembly 2 is 1.0 mm. Since the specific structure is existing technology, it will not be explained here.

[0036] During actual use, the centrifugal fan wheel is changed from using an inner rotor motor to using an outer rotor motor. The outer rotor motor has a compact structure, occupies less space inside the air conditioner, improves space utilization, and is easy to maintain. The stator assembly 3 and the rotor assembly 2 can be separated by removing the retaining spring 32, and the internal structure can be repaired, which reduces disassembly time and reduces maintenance and replacement costs.

[0037] Reference Figure 1 、 2 Specifically, in this embodiment, the magnetic ring 22 is made of a permanent magnet, the outer diameter of the magnetic ring 22 is larger than the inner circumferential wall of the rotor housing 21, and the outer circumferential wall of the magnetic ring 22 is connected to the inner circumferential wall of the rotor housing 21 through an adhesive and an interference fit is performed.

[0038] In actual use, the method of directly sticking the magnetic ring 22 to the rotor housing 21 with an adhesive is simple to operate and has low cost. After the magnetic ring 22 and the rotor housing 21 are connected by interference fit, the gap between the magnetic ring 22 and the rotor housing 21 is filled with adhesive, making the magnetic ring 22 more stable during rotation and reducing vibration and noise.

[0039] Reference Figure 1 、 2 Specifically, in this embodiment, in order to make the connection between the wind wheel assembly 4 and the rotor housing 21 more secure, the inner peripheral wall cover of the wind wheel seat 41 is provided on the outer peripheral wall of the rotor housing 21 and is connected by injection molding through an injection molding machine.

[0040] During actual use, the wind wheel assembly 4 and the rotor housing 21 are connected by injection molding, so that the wind wheel assembly 4, i.e., the centrifugal wind wheel and the rotor housing 21 are tightly combined to form a whole, effectively reducing the loosening or displacement between the wind wheel seat 41 and the rotor housing 21, thereby improving the stability and reliability between the outer rotor motor and the centrifugal wind wheel.

[0041] The first embodiment of the present application further discloses a process for installing a rotor disk of a centrifugal wind wheel, comprising the following steps: S1. Install the rotor assembly 2. Apply adhesive to the inner wall of the rotor housing 21. Then, install the magnetic ring 22 on the inner wall of the rotor housing 21 and connect the rotor housing 21 and the magnetic ring 22 by interference fit. S2. Install the wind wheel assembly 4, set the inner peripheral wall of the wind wheel seat 41 on the outer peripheral wall of the rotor housing 21, and use an injection molding machine to connect the two by injection molding to form a tight combination.

[0042] Example 2: The difference between this embodiment and embodiment 1 is that the connection method between the magnetic ring 22 and the rotor housing 21 and the wind wheel seat 41 is different; Reference Figure 3 Specifically, in this embodiment, the magnetic ring 22 includes a plurality of permanent magnet portions 221 and a plurality of connecting portions 222. The length of the connecting portions 222 is less than that of the permanent magnet portions 221. The plurality of permanent magnet portions 221 are spaced apart from each other. The plurality of connecting portions 222 are respectively disposed between adjacent permanent magnet portions 221 and are integrally formed to form an annular structure adapted to the inner circumferential wall of the rotor housing 21. In order to more accurately install the magnetic ring 22 on the inner wall of the rotor housing 21, a plurality of positioning grooves 211 are provided on the inner bottom of the rotor housing 21. The plurality of positioning grooves 211 are arranged in a circumferential manner with the center position of the bottom of the rotor housing 21 as the center of a circle. A positioning plug 223 is provided at the bottom of each of the plurality of connecting parts 222. The plurality of positioning grooves 211 are arranged corresponding to the plurality of positioning plugs 223. The positioning plugs 223 can be inserted into the positioning grooves 211 for positioning connection.

[0043] During actual use, the positioning plug 223 can be inserted into the positioning groove 211 for positioning connection, ensuring the accuracy of the installation position of the magnetic ring 22 in the rotor housing 21, improving the assembly progress of the motor, and improving the stability of the motor during use. The plug-in setting method does not require complicated alignment and adjustment processes, thereby improving the efficiency of subsequent replacement of the magnetic ring 22.

[0044] Reference Figure 4 、 5 6. Specifically, in this embodiment, a plurality of locking members 5 are provided on the wind rotor seat 41, and the locking members 5 are sequentially passed through the wind rotor seat 41 and the connecting portion 222 of the rotor housing 21 and the magnetic ring 22, and a plurality of locking grooves 411 facing the magnetic ring 22 are opened on the outer peripheral wall of the wind rotor seat 41 along its circumference, and the plurality of locking members 5 are respectively correspondingly arranged in the locking grooves 411, and a locking channel is opened at the bottom of the locking groove 411 near one end of the magnetic ring 22, and the locking channel sequentially passes through the wind rotor seat 41 and the rotor housing 21. , and the bottom of the locking channel extends into the connecting portion 222. A connecting rod 51 is provided in the locking member 5. The outer peripheral wall of the connecting rod 51 is provided with a fine thread, thereby increasing the roughness of the connecting rod 51, thereby increasing the friction between it and the locking member 5. The connecting rod 51 passes through the locking groove 411 of the locking member 5 and is inserted into the connecting portion 222 through the locking channel. The locking member 5 can clamp and fix the connecting rod 51, thereby achieving a fixed connection between the magnetic ring 22, the rotor housing 21 and the wind wheel assembly 4.

[0045] During actual use, a connecting rod 51 with fine threads on the outer surface is provided, and the connecting rod 51 is used to fix the magnetic ring 22, the rotor housing 21 and the wind wheel assembly 4, thereby connecting the magnetic ring 22, the rotor housing 21 and the wind wheel assembly 4 into a whole, thereby enhancing the connection strength between the magnetic ring 22, the rotor housing 21 and the wind wheel assembly 4, and making the rotor assembly 2 more stable when driving the wind wheel assembly 4 to rotate.

[0046] Reference Figure 6 、 7When the two closed doors 6 are aligned and closed, the compression spring 7 remains in a natural state. When the two closed doors 6 are manually opened, the compression spring 7 contracts and deforms. After the connecting rod 51 is inserted into the locking member 5, the compression spring 7 automatically resets and pushes the closed door 6 out of the closed slot, thereby closing the locking slot 411.

[0047] In addition, in order to facilitate opening of the magnetic closed door 6, a sliding groove is provided on the top of the closed door 6 for easy manual operation.

[0048] During actual use, the locking groove 411 is opened and closed by the arc-shaped closing door 6. When the magnetic ring 22, the rotor housing 21 and the wind wheel assembly 4 are fixedly connected, the closing door 6 is closed, so that the locking groove 411 is closed. Since the two closing doors 6 are arc-shaped, they are adapted to the arc shape of the outer peripheral wall of the wind wheel seat 41, so that when the wind wheel seat 41 rotates, it maintains an arc state, reduces air resistance during rotation, reduces energy consumption, and improves the rotation efficiency of the rotor assembly 2.

[0049] Reference Figure 5 、 8 The locking member 53 is actuated by a spring which is adapted to move the spring forward and backward and to move the spring forward and backward so as to move the spring forward and backward relative to each other. The locking seat 54 has an internal thread on its inner circumference, and the release switch 52 has an external thread on its outer circumference. The release switch 52 is inserted into the top of the locking seat 54 and threadedly connected, so that the release switch 52 can be raised and lowered from the top of the locking seat 54. When the release switch 52 is lowered, the top of the clamping claw seat 53 abuts against the bottom of the limit portion 521, thereby clamping and locking the connecting rod 51 that passes through the two. When the release switch 52 is raised, the top of the clamping claw seat 53 disengages from the limit portion 521, thereby unlocking the connecting rod 51 that passes through the two. The clamping claw seat 53 includes a clamping base 531, and a plurality of elastic clamping claw blocks 532 are arranged on the surrounding side of the top of the clamping base 531. The plurality of clamping claw blocks 532 are arranged around the center position of the top of the clamping base 531 as the center of a circle. The space between the plurality of clamping claw blocks 532 is for the connecting rod 51 to pass through. The bottoms of the plurality of clamping claw blocks 532 are fixedly set on the top of the clamping base 531, and the tops of the plurality of clamping claw blocks 532 are all arranged in the limiting portion 521. When the limiting portion 521 is away from the clamping claw block 532, the tops of the plurality of clamping claw blocks 532 expand outward, and the tops of the clamping claw blocks 532 are always located inside the limiting portion 521.

[0050] In actual use, when the connecting rod 51 is inserted into the locking seat 54 and sequentially passes through the release switch 52 and the clamping claw seat 53 into the locking channel, thereby fixing the magnetic ring 22, the rotor housing 21, and the wind wheel assembly 4, the internal threads on the inner circumference of the locking seat 54 engage with the external threads on the outer circumference of the release switch 52, generating friction and preload, so that the limiter 521 locks or unlocks the clamping claw seat 53. Simultaneously, the connecting rod 51 passing through the interior is clamped and fixed by the multiple clamping claw blocks 532. When the bottom of the limiter 521 at the bottom of the release switch 52 abuts the tops of the multiple clamping claw blocks 532, the tops of the multiple clamping claw blocks 532 contract inward to clamp the connecting rod 51. When the bottom of the limiter 521 at the bottom of the release switch 52 no longer abuts the tops of the multiple clamping claw blocks 532, the tops of the multiple clamping claw blocks 532 expand outward to release the connecting rod 51.
