Description

The present invention relates to a fan motor structure having a waterproof and dustproof function and the fan, and more particularly to a fan motor structure having a waterproof and dustproof function capable of preventing damage to the internal structure of the fan due to moisture and dust and the fan.

The fan device is the best method for forcibly radiating heat to heat-generating components, and also has an excellent heat radiating effect.
The fan device includes a fan frame, a stator, and a rotor.
The stator and the rotor are installed in the fan frame, and the stator includes a coil, an electromagnetic steel plate unit, and a support frame.
Furthermore, the circuit boards are connected, whereby the stator and the rotor generate a magnetic field.
The rotor rotates in this way, but each stator and circuit board is in direct contact with air, so that moisture and dust intrude in the air may cause the components to break and become inoperable.

In view of the above problems, a structure has been developed in which a protective layer is installed on the stator surface and the stator and air are separated to achieve waterproofing and dustproofing effects. However, the following drawbacks still exist: To do.
1． The heat generated by the stator is completely trapped in the protective layer and cannot be dissipated because it is not transmitted to the outside world, the stator overheats, stops operation, and is damaged in serious cases.
2． Since the protective layer covers the outside of the stator unit, it cannot be replaced if the stator unit is damaged.
The present invention has been made in view of the above-described drawbacks of conventional fans having waterproof and dustproof functions.

FIG. 6 is a partial anatomical view of the second embodiment of the present invention. FIG. 6 is a partial anatomical view of the second embodiment of the present invention.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings.

1 and 2 are an exploded view and a combined sectional view of the first embodiment of the present invention.

As shown in the figure, the fan motor structure having the waterproof and dustproof functions includes a base 11 on which the shaft cylinder 111 is installed upright, a housing 12 having an annular sealed space 121 for accommodating a stator unit, and the sealed space. It consists of an annular stator unit 13 installed in 121.

The shaft cylinder 111 includes a shaft hole 1111, and at least one bearing 14 is installed in the shaft hole 1111.

The housing 12 is installed by fitting its annular inner wall to the outside of the shaft cylinder 111, and the housing 12 further includes a cover part 122 and a sealing part 123.

The cover portion 122 and the sealing portion 123 are correspondingly joined to define the sealed space 121 as a unit.

The cover portion 122 includes an apex side 1221, an outer first side 1222, and an inner second side 1223, which are suspended from the apex side 1221 and extend toward the base 11.

A sealed space 121 surrounded by the first side 1222, the second side 1223, the apex side 1221 and the base 11 is defined.

The stator unit 13 includes laminated electromagnetic steel sheet pieces 131, and a plurality of coils 132 are wound around the electromagnetic steel sheet pieces 131.

A circuit board 15 is correspondingly connected to one side of the stator unit 13.

3 and 4 are an exploded view and a combined sectional view of the second embodiment of the present invention.

As shown in the figure, a fan of a fan motor structure having a waterproof and dustproof function includes a base 11, a housing 12, a stator unit 13, a frame 16, and a rotor unit 17.

Since some of the components in this embodiment and the correspondence between the components are the same as those in the first embodiment, they will not be described again here.

The most important differences between the present embodiment and the first embodiment will be described below.

The fan of the fan motor structure having a waterproof and dustproof function according to the present embodiment has a plurality of extending ends 1112 extending to the outer edge of the shaft 111 of the base 11, and the frame body 16 is connected to the fan frame frame 2. The rotor unit 17 is rotatably supported by the bearing 14.

The rotor unit 17 includes a shaft rod 171 and a wheel hub 172.

One end of the shaft rod 171 is inserted and installed in the shaft tube 111 and is rotatably supported by the bearing 14.

The opposite end of the shaft 171 is connected to the wheel hub 172, and a plurality of fan blades 173 are provided outside the wheel hub 172, and a magnetic body 174 is annularly installed therein.

In the first and second embodiments described above, the housing 12 accommodates and installs the stator unit 13 and the circuit board 15 in the sealed space 121 therein.

Thereby, it is possible to prevent external moisture and dust from entering the constituent members of the stator unit 13 and the circuit board 15.

The conventional technique employs a plastic injection molding method, and the stator unit 13 and the circuit board 15 are completely sealed by a plastic molded body having an integral structure. Therefore, the stator unit 13 and the circuit board 15 are sealed. When it is necessary to replace the outermost plastic layer, it is necessary to destroy and remove the outer plastic layer outside the stator unit 13 and the circuit board 15, which is very inconvenient.

Moreover, since the plastic outer layer was installed in a manner that tightly covers the outside of the stator unit 13 and the circuit board 15, heat was easily accumulated.

In contrast, in the present invention, the stator unit 13 and the circuit board 15 are accommodated and installed in a sealed space 121 of the housing 12 in such a manner that the housing 12 covers the outside. In addition, since the cover portion 122 and the sealing portion 123 are formed in a combined manner, the sealing portion 123 can be opened or the sealed space 121 can be sealed by a user operation.

Therefore, the user can replace the stator unit 13 and the circuit board 15 at the moment.

Further, the stator unit 13 and the circuit board 15 are accommodated and installed in the sealed space 121, and are not completely in close contact with the housing 12, and there is still a gap space. Can be radiated to the housing 12 and radiated to the outside by the housing 12.

The names and contents of the present invention described above are only used for explaining the technical contents of the present invention, and do not limit the present invention. Equivalent applications based on the spirit of the present invention, or conversion (replacement), replacement, and quantity increase / decrease of parts (structure) are all included in the protection scope of the present invention.

  The present invention has novelty that is a requirement for utility model registration, has sufficient progress compared to similar products of the past, has high practicality, meets social needs, and has a very high industrial utility value. large.
