Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present utility model rather than all
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, broadly falls into the scope of this utility model protection.
It is to be appreciated that if this utility model embodiment relates to directivity instruction (such as upper and lower, left and right, front,
After ...), then directionality instruction is only used for explaining relative between each parts under a certain particular pose (as shown in drawings)
Position relationship, motion conditions etc., if this particular pose changes, then directionality instruction changes the most therewith.

Two " description etc. is only used for describing purpose, and it is not intended that instruction or imply its relative importance or implicit indicate indication
The quantity of the technical characteristic shown.Thus, define " first ", the feature of " second " can be expressed or implicitly include at least one
Individual this feature.It addition, the technical scheme between each embodiment can be combined with each other, but must be with ordinary skill
Based on personnel are capable of, when technical scheme combination occur conflicting maybe cannot realize time will be understood that this technical side
The combination of case does not exists, the most not within the protection domain that this utility model requires.
The utility model proposes a kind of tubular wine wheel.
In this utility model one embodiment, as it is shown in figure 1, this tubular wine wheel includes rotary shaft 2 and is installed on rotary shaft 2
Impeller 1, impeller 1 includes that parallel arrangement of two end plates 3 and two ends one_to_one corresponding are fixed on multiple blades 11 of two end plates 3, extremely
Few end plate 3 is fixed with rotary shaft 2, multiple blades 11 on the circle ring area of rotary shaft 2 axis in spaced apart, and leaf
The quantity of sheet 11 is prime number.Specifically, in tubular wine wheel work process, each blade 11 arrives air supply position due to air-flow and gas
The impact of pressure can produce the vibration exciting noise, owing to the quantity of blade 11 is prime number, if then in units of impeller 1 rotates a circle
Time, the frequency producing this vibration in impeller 1 motor process is prime number, and simultaneously, surrounding also has due to the rotation of impeller 1
There is different frequency of vibration；It is appreciated that prime number and Any Digit relatively prime (i.e. not having identical common divisor outside divisor word 1)
The probability that probability is obviously relatively prime with this numeral more than closing number.
Technical solutions of the utility model, by the blade 11 of tubular wine wheel number is defined to prime number, make blade 11 rotate air-supply
Time produced vibration frequencies of other vibrations of frequency and surrounding the most relatively prime, to reduce blade 11 and surrounding
Resonance, reduces the Rotation Noise of tubular wine wheel.
Table 1
With reference to table 1, comprehensive air quantity and noise two item data consider, during quantity n=37 of blade 11, and the performance of tubular wine wheel
Optimum.
With reference to Fig. 3, further, in the present embodiment, the outer circumference diameter of annulus is d1, 130mm≤d1≤160mm.At present,
Blade 11 number of the impeller 1 on market is commonly 35, outer circumference diameter d1For 30mm～60mm；It is appreciated that 37 leaves of employing
Sheet 11 is while reaching noise reduction, if still using the outer circumference diameter scope of existing 35 blade wind wheel, then owing to adding 2
Blade 11, can cause wind wheel outer peripheral face blade 11 gross area to become big, and accordingly, the air-supply gross area will diminish, so that air quantity fall
Low；The technical program appropriateness increases the diameter range d of wind wheel outer peripheral face1, to ensure the air quantity of wind wheel while noise reduction.Need
Illustrating, the design is not limited to this, and in other embodiments, outer circumference diameter d1 can be not belonging to 130mm～160mm, and passes through
Other modes ensure air quantity.
Further, a diameter of d of the inner circumferential of annulus2, 0.64d1≤d2≤0.9d1.In the case of outer circumference diameter is certain,
So, both ensure that the volume of impeller 1 wind pushing cavity, to provide sufficiently large air quantity, ensure again the air-supply face length degree of blade 11, with
Sufficiently large blast is provided.
Further, multiple blades 11 on circle ring area in unevenly spaced distribution.So, on circle ring area any two
Adjacent blades 11 is different through the time slot of impeller 1 air outlet, then can effectively reduce the superposition of Rotation Noise.
Further, with reference to Fig. 2, impeller 1 is provided with multiple, and the plurality of impeller 1 is spelled on the axial direction of rotary shaft 2 successively
Connect in one.It is appreciated that and is set to wind wheel be made up of multiple impellers 1, wind wheel axial length can increased to increase intake
While avoid blade 11 long and cause it to be easily damaged.Further, two impellers 1 of arbitrary neighborhood, in stitching portion altogether
With an end plate 3.Specifically, end plate 3 is fixed in the end of blade 11；Can be locked by screw such as but not limited to, blade 11,
Bonding agent is bonding or the mode such as clamping is fixed on end plate 3, and this is not restricted by this utility model.Without loss of generality, the present embodiment
In, the end plate 3 being positioned at the axial two edges of wind wheel is circular slab, with the wind pushing cavity from side-closed wind wheel, prevents wind wheel side from running
Wind；And the end plate 3 between two circular slabs is annular, to connect the wind pushing cavity of two adjacent fan-wheel 1.
Further, the blade 11 on two impellers 1 of arbitrary neighborhood mutually staggers arrangement.Specifically, reference Fig. 4, two
Spacing between any two corresponding blades 11 of adjacent fan-wheel 1 is △ S；During wind wheel work, two corresponding blades 11 start simultaneously at fortune
Dynamic, the movement velocity of two blades 11 is identical, but due to the existence of △ S, the distance of both distance air outlets is different, so, will lead
Causing two blades 11, to arrive time of air outlet different, then both to produce times of noise and vibrations different, it is to avoid synchronization two
The superposition of person's noise is preferred, and the blade 11 on any two impellers 1 mutually staggers arrangement, to avoid between any two impellers 1
Raw superimposed noise.Meanwhile, when blade 11 locks for screw or the mode of grafting is fixed on end plate 3, the blade 11 of end plate 3 both sides
Arrangement of staggering is more convenient for the installation of blade 11.
This utility model also proposes a kind of cross flow fan, and this cross flow fan includes tubular wine wheel, this tubular wine wheel concrete
Structure, with reference to above-described embodiment, owing to cross flow fan have employed whole technical schemes of above-mentioned all embodiments, the most at least has
All beneficial effects that the technical scheme having above-described embodiment is brought, this is no longer going to repeat them.
This utility model also proposes a kind of indoor apparatus of air conditioner, and this indoor apparatus of air conditioner includes cross flow fan, this cross flow fan bag
Including tubular wine wheel, the concrete structure of this tubular wine wheel is with reference to above-described embodiment, owing to cross flow fan have employed above-mentioned all enforcement
Whole technical schemes of example, the most at least have all beneficial effects that the technical scheme of above-described embodiment is brought, at this not
Repeat the most one by one.
These are only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
Under utility model of the present utility model is conceived, the equivalent structure utilizing this utility model description and accompanying drawing content to be made becomes
Change, or directly/be indirectly used in other relevant technical fields and be included in scope of patent protection of the present utility model.
