Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, specifically to a hair dryer motor with open guide vanes. Background Technology

[0002] A hair dryer is an appliance primarily used for drying and styling hair. It typically consists of a heating element and a small, high-speed fan. When powered on, the heating element generates heat, and the air blown by the fan passes through it, becoming hot air. If only the fan is running but the heating element isn't heating up, cold air will be blown out. The fan's rotation is driven by a motor, and current hair dryer motors are relatively large and heavy, taking up significant installation space. Reducing the overall size also decreases the ventilation area, lowering drying efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a blower motor with open guide vanes, which reduces the size while relatively increasing the ventilation area and saving motor space.

[0004] Specifically, this utility model discloses a hair dryer motor with open guide vanes, including: a rotor assembly, a stator assembly, a fan assembly, and a housing assembly. The stator assembly is fixed inside the housing assembly, the rotor assembly is disposed inside the stator assembly, and the fan assembly is connected to the rotor assembly. The housing assembly includes: an outer housing and a connecting housing. A plurality of open guide vanes are disposed between the outer housing and the connecting housing, and a flow channel is formed between the open guide vanes. The open guide vanes extend from the end of the outer housing.

[0005] The advantage of adopting the above technical solution is that by setting open guide vanes, the overall volume can be reduced without reducing the area of ​​the ventilation channel, thus saving motor space.

[0006] Furthermore, the connecting housing includes a stator mounting section and a support section. The stator mounting section is used to fix the stator, and the support section is close to the fan assembly. The diameter of the support section is smaller than that of the stator mounting section.

[0007] The advantage of adopting the above technical solution is that, in order to ensure the efficiency of the motor, the stator diameter cannot be too small. Therefore, a stator mounting section is set to install the stator assembly. At the same time, the diameter of the support section is small, which can reduce the diameter of the entire fan casing and reduce the space occupied. However, due to the reduction in the diameter of the support section, the area of ​​the air guiding channel is relatively increased, thus ensuring the blowing efficiency.

[0008] Furthermore, the stator mounting section and the support section are connected by an arc-shaped transition surface, and the distance between the upper surface of the outer shell and the bottom of the arc-shaped transition surface is 20-40mm.

[0009] The advantage of adopting the above technical solution is that while the diameter of the outer casing is greatly reduced, the airflow generated by the fan assembly flows out from the gap between the outer casing and the arc transition surface, which relatively increases the area of ​​the airflow channel and reduces the space occupied by the motor.

[0010] Furthermore, the open guide vane extends 6-15 mm beyond the outer housing.

[0011] The advantage of adopting the above technical solution is that by setting up extended open guide vanes, the ventilation channel is not reduced while the outer shell is reduced, thus ensuring air blowing efficiency.

[0012] Furthermore, the connecting housing is provided with multiple mounting slots, and the stator assembly is provided with a fixing part, which is installed in conjunction with the mounting slots.

[0013] The advantages of adopting the above technical solution are that the installation groove and the fixing part are matched, which facilitates the installation of the stator assembly, improves the installation efficiency, and effectively prevents the stator assembly from moving.

[0014] Furthermore, the rotor assembly includes a shaft and a rotor, the rotor being sleeved on the shaft and rotating with the shaft, the shaft being connected to the fan assembly.

[0015] Furthermore, the fan assembly includes a fan body and fan blades disposed around the fan body. The fan body is provided with mounting holes for connection with the rotating shaft, and the fan body is located inside the outer housing.

[0016] The advantage of adopting the above technical solution is that a rotating shaft drives the fan to rotate, thereby achieving air blowing.

[0017] Furthermore, the stator assembly includes: a stator core, a stator fixing frame, and a stator winding, wherein the stator fixing frame is used to fix the stator core, and the stator winding is wound around the outside of the stator core.

[0018] Furthermore, the upper end of the open guide vane is provided with an inclined surface, which forms an angle with the outer surface of the connecting housing.

[0019] The advantage of adopting the above technical solution is that the inclined surface reduces turbulence, which can reduce motor noise and extend service life. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] like Figure 1-2 As shown, this utility model discloses a hair dryer motor with open guide vanes, including: a rotor assembly 1, a stator assembly 2, a fan assembly 3, and a housing assembly. The stator assembly 2 is fixed inside the housing assembly, the rotor assembly 1 is disposed inside the stator assembly 2, and the fan assembly 3 is connected to the rotor assembly 1. The housing assembly includes: an outer housing 4 and a connecting housing 5. A plurality of open guide vanes 6 are disposed between the outer housing 4 and the connecting housing 5, forming a flow channel between the open guide vanes 6. The open guide vanes 6 extend from the end of the outer housing 4, and all open guide vanes 6 rotate a certain angle in the same direction on the outer surface of the connecting housing 5.

[0030] The advantage of adopting the above technical solution is that by setting open guide vanes 6, the overall volume is reduced without reducing the area of ​​the ventilation channel, thus saving motor space.

[0031] In some embodiments, the connecting housing 5 includes a stator mounting section 51 and a support section 52 (e.g., Figure 3As shown, the stator mounting section 51 is used to fix the stator, and the support section 52 is close to the fan assembly 3. The diameter of the support section 52 is smaller than that of the stator mounting section 51. To ensure the efficiency of the motor, the stator diameter cannot be too small. Therefore, the stator mounting section 51 is set to install the stator assembly 2. At the same time, the diameter of the support section 52 is small, which can reduce the diameter of the entire fan casing and reduce the space occupied. However, due to the reduction in the diameter of the support section 52, the area of ​​the airflow channel is relatively increased to ensure the blowing efficiency.

[0032] Furthermore, the stator mounting section 51 and the support section 52 are connected by an arc-shaped transition surface. The distance between the upper surface of the outer housing 4 and the bottom of the arc-shaped transition surface is 20-40mm. The outer side of the outer housing is covered by a blower housing, which is also covered by the outer side of the open guide vane 6. As the diameter of the outer housing 4 decreases, the airflow generated by the fan assembly 3 flows out from the gap between the outer housing 4 and the arc-shaped transition surface and enters the channel formed by the blower housing and the open guide vane 6, thereby increasing the area of ​​the guide channel and reducing the space occupied by the motor.

[0033] Furthermore, the open guide vane 6 extends 6-15mm beyond the outer casing 4. By setting the extended open guide vane 6, the ventilation channel is not reduced while the outer casing 4 is reduced, thus ensuring airflow efficiency.

[0034] In some implementations, the connecting housing 5 is provided with a plurality of mounting slots 53, and the stator assembly 2 is provided with a fixing part 21, which is installed in conjunction with the mounting slots 53.

[0035] The advantage of adopting the above technical solution is that the installation groove 53 cooperates with the fixing part 21, which facilitates the installation of the stator assembly 2, improves the installation efficiency, and effectively prevents the stator assembly 2 from moving.

[0036] Furthermore, the rotor assembly 1 includes a shaft 11 and a rotor 12 (e.g., Figure 4-5 As shown, the rotor 12 is mounted on the rotating shaft 11 and rotates with the rotating shaft 11. The rotating shaft 11 is connected to the fan assembly 3, and a bearing is mounted on the outer side of the rotating shaft 11. The bearing is installed in the connecting housing. The fan assembly 3 includes a fan body 31 and fan blades 32 arranged around the fan body 31. All fan blades 32 are inclined. The rotating shaft 11 rotates within the support section 52. The fan body 31 is provided with mounting holes to connect with the rotating shaft 11. The fan body 31 is located inside the outer housing 4 and on the side of the end of the support section 52. The air generated after the fan body 31 rotates flows out from the guide channel.

[0037] In some embodiments, the stator assembly 2 includes a stator core 22, a stator retainer 23, and a stator winding, wherein the stator retainer 23 is used to fix the stator core 22, and the stator winding is wound around the outside of the stator core 22.

[0038] Furthermore, the upper end of the open guide vane 6 is provided with an inclined surface 61, which forms an angle with the outer surface of the connecting housing 5, and the angle is between 60 degrees and 70 degrees.

[0039] The advantage of adopting the above technical solution is that the inclined surface 61 reduces turbulence, which can reduce motor noise and extend service life.

[0040] During operation, the motor rotor assembly 1 rotates, driving the fan assembly 3 to rotate. The blown air flows out through the guide channel, realizing the blowing function. The diameter of the outer shell is reduced, but the volume of the guide channel is not reduced, which reduces noise, ensures blowing efficiency, and extends service life.

[0041] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
