Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

The fan 100 proposed by the present invention is described below with reference to fig. 1 to 3, and an air treatment apparatus having the fan 100 described above is also proposed. In particular, the air treatment device may be an air conditioner or a humidifier.

As shown in fig. 1 to 3, the fan 100 includes: a plurality of blades 20 and a hub 10, the hub 10 comprising: the wheel hub comprises a mounting disc 11, a plurality of wheel hub pieces 12, a plurality of connecting ribs 13 and a chassis 14, wherein a motor shaft hole is formed in the mounting disc 11, two ends of the plurality of wheel hub pieces 12 are respectively connected between the mounting disc 11 and the chassis 14 and are distributed at intervals in the circumferential direction to limit a wheel hub hole 15. Wherein, when the fan 100 is operated, air enters the fan 100 from the air inlet, and the air flow along the hub 10 is gently changed from axial flow to radial flow, during which the air flow near the center of the hub 10 still passes through the hub hole 15 to take away the heat of the motor through heat-extraction heat exchange. When the air flow near the center of the hub 10 carries the heat of the motor through the hub aperture 15, it will then continue to flow down the hub 10 and radially along the hub 10.

As shown in fig. 1 and 2, two ends of the plurality of connecting ribs 13 are respectively connected to the chassis 14 and the hub plate 12, the chassis 14 is provided with a plurality of first gluing holes 16 and a plurality of second gluing holes 17, the plurality of first gluing holes 16 respectively correspond to the plurality of hub plates 12 to glue the hub plate 12, and the plurality of second gluing holes 17 respectively correspond to the plurality of connecting ribs 13 to glue the hub plate 12 through the connecting ribs 13. That is, the hub 10 is molded by the first and second molding holes 16 and 17. Also, since the hub plate 12 is connected to the connecting ribs 13 and the size of the hub plate 12 is larger than that of the connecting ribs 13, when the connecting ribs 13 are filled with the molten liquid material entering from the second gluing holes 17 during the molding of the hub 10, the molten liquid material flows toward the hub plate 12. Thus, the forming speed at the hub plate 12 is faster than that without the connecting ribs 13, that is, the forming speed of the hub 10 is fast, so that the deformation of the chassis 14 is small, the deviation of the center of mass of the hub 10 from the center is small, that is, the radial runout of the fan 100 is small, and the dynamic balance is good. Thus, when the motor is driven by the fan 100, the noise generated when the motor drives the fan 100 is relatively small.

Also, a plurality of blades 20 are provided on the base plate 14, and the plurality of blades 20 are provided at intervals in the circumferential direction. Specifically, a base plate 14 is provided at the upper end of the blades 20, and a base is provided at the upper end, and the blades 20 are fixed together to prevent the blades 20 from being subjected to vibration generated when the fan 100 is rotated at a high speed and noise generated thereby.

In addition, the connecting base of the fan 100 is provided with a motor shaft hole, the motor shaft hole is matched and fixed with the motor shaft of the motor, and the hub plate 12 is used for connecting the motor shaft hole part and the blade 20 part. Based on consideration of the size of the air treatment apparatus, the hub 10 is usually recessed into the fan 100, that is, the receiving space 30 is formed on the hub 10, and the motor is mounted in the receiving space 30, so that the motor can be avoided, that is, the size of the air treatment apparatus can be reduced.

Therefore, the connecting ribs 13 are arranged between two adjacent hub plates 12, the first gluing holes 16 corresponding to the hub plates 12 and the second gluing holes 17 corresponding to the connecting ribs 13 are arranged on the chassis 14, so that the hub 10 is fast in molding, the deformation of the part of the chassis 14 is small, the deviation of the center of mass of the hub 10 from the center is small, and the noise generated by the fan 100 in use is low.

As shown in fig. 1, the connecting rib 13 includes: main muscle section 131 and two at least branch muscle sections 132, the one end of main muscle section 131 is connected on chassis 14 to extend towards mounting disc 11, the other end at main muscle section 131 is all connected to two at least one ends that divide muscle section 132, and extends towards the wheel hub piece 12 of both sides, and the other end that two at least branch muscle sections 132 is connected respectively on the wheel hub piece 12 of both sides. That is, the extending direction of the main rib section 131 is the same as the extending direction of the hub piece 12, and the direction of the liquid material in the molten state entering the hub 10 from the first gluing hole 16 and the second gluing hole 17 is the same, so that the material can conveniently enter the hub piece 12 through the main rib section 131 and the rib dividing section 132. In addition, the main rib sections 131 and the sub-rib sections 132 can connect two adjacent hub plates 12, so that the structural strength of the hub 10 can be improved, and the hub 10 can operate more stably.

As shown in fig. 1, there may be two rib dividing sections 132, two rib dividing sections 132 extend from the connecting end of the main rib section 131 to the opposite extending direction, and the extending lengths of the two rib dividing sections 132 are the same. When the number of the rib-dividing sections 132 is two, the hub pieces 12 on two sides of the main rib section 131 are respectively connected with the rib-dividing section 132, so that when the hub 10 is molded, the liquid material enters the connecting rib 13 through the second glue-applying hole 17, specifically, the liquid material firstly flows through the main rib section 131, and then flows to the two adjacent hub pieces 12 through the two rib-dividing sections 132, namely, the molding speed of the fan 100 is higher than that when the connecting rib 13 is not added, the molding speed of the hub 10 is higher, the deformation of the chassis 14 part of the fan 100 is small, the center of mass deviation is small, the radial runout of the fan 100 is small, and the dynamic balance is good.

As shown in fig. 1 and 2, the number of the hub plates 12 may be three, the number of the connecting ribs 13 may be three, and the rib segments 132 are connected to two opposite sides of each hub plate 12. When the fan 100 is used, in order to save materials and improve the performance of the air duct, the hub hole 15 needs to be formed on the hub 10, and the number of the hub holes 15 has obvious influence on the air volume, noise and power of the motor. Among them, the fan 100 with three hub holes 15 has great advantages in terms of sound quality, that is, the hub 10 is provided with three hub plates 12, and there are three connecting ribs 13 connected to two adjacent hub plates 12, so that the air volume of the fan 100 can be increased, and the noise can be reduced.

Moreover, through the hub hole 15 with the structure, the air flow can not be separated at the hub hole 15, and under the condition of meeting the strength of the hub 10 and the heat dissipation requirement of the motor, the phenomenon that the air flow flowing in from the air inlet is separated at the hub hole 15 under the condition of low rotating speed can be eliminated, so that the air turbulence is eliminated, and the flowing noise is reduced. Meanwhile, since the extension area of the hub hole 15 is enlarged, the weight of the hub 10 can be reduced and the heat dissipation effect can be increased to some extent, thereby reducing the cost of the motor and the power consumption of the motor.

As shown in fig. 3, the width of the hub plate 12 is h1, the width of the main rib segment 131 is h2, and h1 and h2 satisfy the relationship: h2 is more than or equal to 0.3h1 and less than or equal to 0.5h 1. That is to say, the width of the main rib section 131 is 0.3-0.5 times of the width of the hub plate 12, that is, the width of the main rib section 131 is smaller than the width of the hub plate 12, which not only facilitates the liquid material in the molten state to enter the hub plate 12 through the connecting rib 13, but also avoids affecting the size of the hub hole 15, that is, does not affect the working efficiency of the fan 100.

As shown in fig. 3, the width of the rib-dividing section 132 is h3, and h3 and h1 satisfy the relation: h3 is more than or equal to 0.3h1 and less than or equal to 0.5h 1. That is to say, the width of the rib dividing section 132 is 0.3-0.5 times of the width of the hub plate 12, that is, the width of the rib dividing section 132 is smaller than the width of the hub plate 12, which not only facilitates the liquid material in the molten state to enter the hub plate 12 through the connecting rib 13, but also avoids affecting the size of the hub hole 15, that is, does not affect the working efficiency of the fan 100. The main rib section 131 and the sub rib section 132 can have the same size, so that the liquid material in a molten state can be more stable when entering the hub sheet 12 from the connecting rib 13.

As shown in fig. 3, the distance from the rib dividing section 132 to the mounting plate 11 is h4, the distance from the rib dividing section 132 to the chassis 14 is h5, and h4 and h5 satisfy the following relation: h 4-h 5. That is to say, the rib dividing section 132 is arranged at the middle position of the hub plate 12 in the up-down direction, so that when the hub 10 is molded, the liquid material in a molten state can enter the hub plate 12 from the first gluing hole 16, and can also enter the connecting rib 13 from the second gluing hole 17 and then enter the hub plate 12, so that the hub plate 12 can be glued between the position corresponding to the rib dividing section 132 and the mounting plate 11 through the first gluing hole 16 and the second gluing hole 17, thereby improving the molding speed of the hub 10, and the centroid deviation center of the hub 10 during molding is small, the radial runout of the fan 100 is small, that is, the noise of the fan 100 during operation is small.

Wherein the inner surface of the hub plate 12 and the inner surface of the adjacent connecting rib 13 are positioned in the same arc-shaped plane or curved plane. So set up for wheel hub 10 is located same arcwall face or curved surface towards first one side of gluing hole 16 and the second hole 17 of gluing, can make things convenient for wheel hub 10's shaping to and promote the air current at wheel hub 10 operating stability, reduce the noise that the air current flows the production.

As shown in fig. 1 and 2, the plurality of first gluing holes 16 and the plurality of second gluing holes 17 are distributed in a staggered manner in the circumferential direction of the base plate 14, and the distances between adjacent first gluing holes 16 and adjacent second gluing holes 17 are the same, and the diameters of the first gluing holes 16 and the second gluing holes 17 are the same. Therefore, the first gluing hole 16 and the second gluing hole 17 have the same aperture, so that the first gluing hole 16 and the second gluing hole 17 have the same speed when gluing, and therefore, when the hub 10 is molded, the hub 10 is molded at a high speed, the chassis 14 is deformed less, the center of mass of the hub 10 deviates less, the fan 100 has small radial run-out and good dynamic balance when running. In addition, the distance between the adjacent first gluing holes 16 and the adjacent second gluing holes 17 is the same, so that the hub 10 can be molded more uniformly.

According to the second aspect of the present invention, an air treatment device comprises a fan 100. That is, the fan 100 is installed in the air treatment device. The air treatment device further comprises a motor, the fan 100 being mounted on an output shaft of the motor. The motor may rotate the fan 100 by the rotation of the output shaft. Therefore, the air treatment equipment provided with the fan 100 has the advantages that the deformation of the part of the chassis 14 is small, the center of mass is slightly deviated from the center, the radial runout of the fan 100 is small, namely, the noise generated by the fan 100 when the air treatment equipment is used is small, the air treatment equipment is safer, and the service life is longer. The air treatment equipment can be a mobile air conditioner or a dehumidifier.
