Specific embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
Refer to shown in Fig. 1, fan fixed structure 100 of the present invention is used for refrigerator, including blower fan 10 and described blower fan 10 phase
Described blower fan 10 is fixed on the fixture on described air channel 20, by the air channel 20 and at least three of cooperation in described fixture extremely
Rare one is to have resilient stationary rope 30.One end of described stationary rope 30 is fixed on described blower fan 10, the other end
It is fixed on described air channel 20, and be in tensioned state.In the present embodiment, described fixture is all to have resilient static line
Rope 30, but in other embodiments, described fixture can also be partly screw, partly for having resilient stationary rope
30.Described stationary rope 30 is rubber rope.
Refer to shown in Fig. 2, described blower fan 10 includes mounting seat 11 and is installed on blade 12 in described mounting seat 11,
On the side wall of described mounting seat 11, outward has the blower fan pillar 111 matching with described stationary rope 30, described static line
Rope 30 is fixed on described blower fan pillar 111.Holding section 112 is provided with described blower fan pillar 111, described holding section 112 is
Run through the through hole of described blower fan pillar 111.In the present embodiment, described holding section 112 is to run through leading to of described blower fan pillar 111
Hole, but in other embodiments, described holding section 112 can also be groove.
Refer to Fig. 4 and combine shown in Fig. 1, described air channel 20 is in circular, and its sidewall edge is provided with and described fixation
The groove 21 that rope 30 matches, the openings of sizes of described groove 21 becomes big from the outside to the core.In the present embodiment, described groove 21
Section L-shaped, and its openings of sizes becomes big from the outside to the core, but in other embodiments, the opening of described groove 21 is big
Little can also be set to first taper into from outside to inside and then become larger again.
Refer to Fig. 1 and combine shown in Fig. 3, described stationary rope 30 includes main part 32 and is located at described main body respectively
The elastic tightening sealing 31 at portion 32 two ends and fixed part 33.Described elastic tightening sealing 31 is in hollow form, coats described blower fan and props up
Post 111, and described blower fan pillar 111 is applied with the power in the direction along described elastic tightening sealing 31 contraction, so that described
Between blower fan pillar 111 and described elastic tightening sealing 31, there is larger frictional force, reaching will be solid for described elastic tightening sealing 31
Purpose on described blower fan pillar 111.The inner side of described elastic tightening sealing 31 is provided with and is matched with described holding section 112
The hangnail 311 closing.When described elastic tightening sealing 31 coats described blower fan pillar 111, described hangnail 311 is held in described card
Hold in portion 112 so that described elastic tightening sealing 31 is tightly fixed on described blower fan pillar 111.Described main part 32 away from
One end of described elastic tightening sealing 31 is held in described groove 21.Described main part 32 is fixed on institute by described fixed part 33
State in groove, and make described main part 32 be in tensioned state.In the present embodiment, the quantity of described stationary rope 30 is three
Root, but in other embodiments, the quantity of described stationary rope 30 can according to demand depending on.
After described blower fan 10, air channel 20 and stationary rope 30 assemble, described in described three stationary rope 30 deciles
Air channel 20, the angle between adjacent two described stationary ropes 30 is 120 degree, and described three stationary ropes 30 are to described wind
The direction of the power that machine 10 applies intersects at a point.In the present embodiment, air channel 20 described in described stationary rope 30 decile, but
In other embodiments, described rope 30 can not also air channel 20 described in decile.
Compared to prior art, fan fixed structure 100 of the present invention is due to being fixed on blower fan 10 by stationary rope 30
On air channel 20, so that when blower fan 10 runs, described blower fan 10 and air channel 20, stationary rope 30 will not produce resonance, and then
Reduce noise when blower fan 10 runs.Secondly, the production cost of described fan fixed structure 100 is relatively low, be easily assembled.?
Afterwards, the both sides of described blower fan 10 not thing stop, thus the mobility of gas is strengthened when blower fan 10 runs.
