Detailed description of the invention
This utility model provides a kind of range hood, including body and spiral case 1, is provided with impeller and impeller in spiral case 1
Motor 2, as depicted in figs. 1 and 2, motor 2 is fixed with spiral case 1 by support 3 and is connected, and support 3 includes fixed part 31 and leg
32, fixed part 31 is the circulus of wound motor 2 center of rotation, and motor 2 is fixed on fixed part 31, and leg 32 is along fixing
The neighboring in portion 31 arranges and extends to spiral case 1 direction, and leg 32 is fixing with spiral case 1 to be connected.
In this utility model, carry out contacting connection by the fixed part 31 of circulus with motor 2, and motor 2 is fixed
On the fixed part 31 of circulus, owing to motor 2 center of rotation passes from the circulus that fixed part 31 is formed, fixed part
Axial, the radial direction of motor 2 and circumferencial direction can be positioned by 31, the most simple and convenient, and the fixing benchmark of motor 2 is only
One determines, can avoid the inconsistent situation causing motor shaft eccentric of setting height(from bottom) of motor 2 different parts, it is ensured that motor 2 is accurate
Really install, it is advantageously ensured that the work efficiency of motor 2.Circulus refers to be formed the structure of closed-loop, except circle, in reality
In product, it would however also be possible to employ oval or polygon or the closed-loop of other shapes.
Rotor rotation due to motor 2 can produce the active force of direction of rotation, causes the stator of motor 2 to produce centrifugal force,
Therefore to make motor 2 more stable, fixed part 31 can uniform force, reduce vibration, fixed part 31 is set to circular
Fixed platform, in fixed platform, the surface of positioning motor 2 easily carries out being accurately positioned of polish, beneficially motor 2, makes simultaneously
Motor 2 is close on the stationary platform, and the rotor of motor 2 rotates the active force of generation direction of rotation can be by fixed platform and electricity
The frictional force produced between machine 2 is offset so that motor 2 rotates more stable, reduces vibration.
Certainly, during fastening with fixed part 31 at motor 2, the external force being likely to be due to fastening applies excessive, and
There is slight deformation in the position causing motor 2 and fixed part 31 to contact with each other, so the surface of positioning motor 2 on the stationary platform
It is provided with deep gouge, the contact area of fixed part 31 and motor 2 can be reduced so that the installation deviation that deformation brings can reach to ignore
The degree disregarded.
In order to motor 2 is easy for installation with support 3, motor 2 is fixed on fixed part 31 by threaded fastener, screw threads for fastening
Part has self-lock ability, the most also can keep the connection reliability between motor 2 and fixed part 31 for a long time.And be
The reliability that further raising motor 2 is connected with fixed part 31, threaded fastener includes blind nut 41 and fixing screw 42,
Blind nut 41 is fixed on fixed part 31, and motor 2 is provided with screwing through hole, and fixing screw 42 is through screwing through hole and blind nut
Motor 2 is fixed by 41 connections.Owing to support 3 is that stamped from sheetstock processes, therefore thickness is less, if passing through merely screw
Connecting, reliability is relatively low, therefore increases blind nut 41 on fixed part 31, thus increases effective with what fixing screw 42 was connected
Connecting length, is greatly improved reliability.
Version as leg 32 can have various ways, illustrates below in conjunction with specific embodiment.
Embodiment one:
In conjunction with shown in Fig. 1 to Fig. 3, leg 32 includes the sidewall 321 that multiple and fixed part 31 neighboring is connected, sidewall
321 extend to spiral case 1 direction, form breach 320 between the most adjacent sidewall 321, and the opening of breach 320 is towards spiral case 1.Lack
Mouth 320 can realize the ventilation inside and outside sidewall 321, has the heat radiation being in motor 2, and sidewall 321 is in fixed part 31 neighboring simultaneously
Size on edge is shorter so that sidewall 321 can have a little elasticity capacity bearing deformation, therefore can reduce motor 2 and produce
Vibration be delivered to the degree of spiral case 1.The most most important or the stability maintenance of motor 2, the most adjacent sidewall
Connecting between 321 has rib 322, rib 322 to be connected with fixed part 31, and rib 322 forms the blind end of breach 320.
The existence of rib 322, so that can keep relative position relationship, it is ensured that leg between the most adjacent sidewall 321
During 32 is fixing with spiral case 1, do not have, between sidewall 321, deviation occurs, avoid motor shaft eccentric as far as possible or tilt.
Sidewall 321 is relatively thin, is connected if the end face of sidewall 321 is directly fixing with spiral case 1, less stable, to this end, leg
32 also include that flange 323, flange 323 are connected to the neighboring of fixed part 31 by sidewall 321, and flange 323 is fixedly connected on
The inner side of spiral case 1.Typically flange 323 is welded and fixed with spiral case 1, owing to the contact area of flange 323 with spiral case 1 increases, because of
This is conducive to welding, improves leg 32 and the fixing stability of spiral case 1.It addition, motor 2, support 3 are all located at the inner side of spiral case 1,
Therefore flange 323 is fixedly connected on the inner side of spiral case 1, and motor 2, impeller, support 3 are all hidden in spiral case 1 so that spiral case 1
Outward appearance is more preferable, is also more convenient for installing.Certain flange can also stretch out spiral case and be fixed on the outside of spiral case.
Pre-determined bit when welding for the ease of support 3, flange 323 is provided with hole 324, location, and spiral case 1 is provided with convex
Point, positioning convex point enters and makes support 3 obtain pre-determined bit, convenient welding in hole 324, location, improves welding efficiency.
Embodiment two:
As shown in Figure 4 and Figure 5, in the present embodiment, leg 32 includes arranging cyclization along the neighboring of fixed part 31
The sidewall 321 of shape, i.e. sidewall 321 form closed-loop as fixed part 31, corresponding with sidewall 321, and flange 323 is also envelope
Closed-loop structure.In the present embodiment, the intensity of sidewall 321 is improved, and the stability of motor 2 can be more preferably.
Owing to not having breach 320, therefore sidewall 321 is provided with the through hole 325 run through, thus promotes the heat radiation of motor 2.Separately
External flange is provided with the location hole 324 in mating connection with the positioning convex point on spiral case 1.
In embodiment one, it is also possible to increase through hole on sidewall 321 and promote heat radiation.
In addition to above preferred embodiment, this utility model also has other embodiment, and those skilled in the art can root
It is variously modified according to this utility model and deforms, without departing from spirit of the present utility model, this utility model all should be belonged to
