Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings.Below with reference to accompanying drawing
The embodiment described is exemplary, it is intended to is used for explaining the present invention, and is not considered as limiting the invention.
Describing spiral case assembly 100 according to embodiments of the present invention below in conjunction with the accompanying drawings in detail, this spiral case assembly 100 can be applied
In range hood.
As depicted in figs. 1 and 2, spiral case assembly 100 may include that spiral case 10 and sound-absorbing material 20, spiral case 10 have into
Air port, air outlet and multiple bloop 111, multiple bloops 111 constitute noise reduction region 11, and wherein motor and impeller are arranged
In spiral case 10, the wind entered from air inlet is guided air outlet under the effect of motor by impeller, and wherein motor and impeller produce
Noise outwards can be appeared by multiple bloops 111, multiple bloops 111 can eliminate a part the most to a certain extent
Noise, as shown in Figure 3 and Figure 6, multiple bloops 111 can be evenly distributed on spiral case 10.Bloop 111 can set
Being set to the hole of minor diameter, choose for aperture, staff can select according to the type of practical condition and range hood
Take.The less bloop 111 in aperture can effectively prevent fluid from passing through bloop 111, thereby may be ensured that bloop 111
Smoothness.
As it is shown on figure 3, spiral case 10 may include that spiral case coaming plate 12 and spiral case side plate 13, spiral case side plate 13 can be two,
Two spiral case side plates 13 lay respectively at the both sides (front side and rear side) of spiral case coaming plate 12, as shown in Figure 6, multiple bloops
111 are formed on spiral case coaming plate 12, and the structure of spiral case coaming plate 12 is reliable and area is relatively big, such that it is able to be easy to multiple noise reduction
The layout in hole 111, can reduce the layout difficulty of multiple bloop 111.Multiple bloops 111 can choose spiral case coaming plate
12 suitable location arrangements, such as, as it is shown on figure 3, multiple bloop 111 can be formed at the top of spiral case coaming plate 12,
So can effectively prevent fluid from flowing to multiple bloop 111, thereby may be ensured that the smoothness of multiple bloop 111.
As shown in Figure 2 and Figure 5, sound-absorbing material 20 covers multiple bloop 111, so appears from multiple bloops 111
Noise can enter in sound-absorbing material 20, and a part of acoustic energy is reflected by sound-absorbing material 20, and another part acoustic energy is by sound absorber
Material 20 is absorbed into heat energy, thus sound-absorbing material 20 can reduce the noise in spiral case 10, can reduce range hood
Noise.Wherein, sound-absorbing material 20 can be acoustical cotton, and certain present invention is not limited to this, and sound-absorbing material 20 can also be
The materials such as sponge.
A specific embodiment according to the present invention, as depicted in figs. 1 and 2, spiral case 10 can also include: outlet installing plate
30, limit snail tongue 31 between outlet installing plate 30 and spiral case coaming plate 12, multiple bloops 111 are adjacent to snail tongue 31.So
Sound-absorbing material 20 can absorb the noise at snail tongue 31 with emphasis adjacent to snail tongue 31, sound-absorbing material 20, can reduce spiral case 10
In snail tongue 31 at noise, such that it is able to effectively reduce the overall noise of range hood, can effectively reduce at snail tongue 31
Design, manufacture difficulty.
In order to preferably absorb the noise in spiral case 10, the lower surface of sound-absorbing material 20 can abut on spiral case coaming plate 12.
Spiral case coaming plate 12 is curved, and as shown in Figure 4, the lower surface of energy-absorbing material is configured to the outer surface phase with spiral case coaming plate 12
The arc joined, such that it is able to improve the sound-absorbing material 20 layout reliability on spiral case coaming plate 12, and can be so that sound-absorbing
Material 20 absorbs noise.
Multiple bloops 111 are formed on the first paragraph molded line on spiral case coaming plate 12, are provided with impeller in spiral case 10, and first
Segment type line is positioned at the first quartile with the center of impeller as initial point and the second quadrant, and first paragraph molded line is near snail tongue 31.
Thus, multiple bloops 111 may be located at the top of spiral case coaming plate 12, and multiple bloop 111 can be near snail tongue
31, sound-absorbing material 20 can be near snail tongue 31, and such bloop 111 and sound-absorbing material 20 can preferably eliminate spiral case 10
Interior noise, such that it is able to effectively reduce the noise in spiral case 10.
Shown in Fig. 2, the inner surface of sound-absorbing material 20 can abut on snail tongue 31 and outlet installing plate 30.So inhale
Sound material 20 can preferably reduce the noise at snail tongue 31, so that the noise of spiral case 10 is relatively low, so that
The noise of range hood is relatively low.
In order to ensure that sound-absorbing material 20 covers the reliability of multiple bloop 111, as shown in Figure 1 and Figure 4, spiral case assembly 100
Can also include: installing rack 40, installing rack 40 is arranged on spiral case 10, and sound-absorbing material 20 is limited by installing rack 40
Between multiple bloops 111 and installing rack 40 of spiral case 10.In other words, installing rack 40 is so that sound-absorbing material 20
Cover on multiple bloops 111, so that sound-absorbing material 20 stably absorbs the noise in spiral case 10.
As shown in Figure 4, installing rack 40 has two installation sites, and two installation sites are respectively the first installation site 41 He
Second installation site 42, installing rack 40 can be arranged at snail tongue 31 by the first installation site 41, the second installation site 42
The lower end of installing rack 40 can be arranged on spiral case 10, such that it is able to installing rack 40 is preferably arranged on spiral case 10,
And between installing rack 40 and spiral case 10, can preferably limit sound-absorbing material 20.
As shown in Figure 4, the downside of installing rack 40 and interior open, the lower surface of such sound-absorbing material 20 can directly contact
Noise reduction region 11, can so that being entered directly in sound-absorbing material 20 by the noise of multiple bloops 111, such that it is able to
Improve the ability that sound-absorbing material 20 abates the noise, can effectively eliminate the noise at snail tongue 31.
Alternatively, the central angle alpha corresponding to noise reduction region 11 that multiple bloops 111 are formed can meet: α ＜ 90 °.
So while ensureing spiral case coaming plate 11 structural strength, it is also possible to the layout quantity making bloop 111 is suitable, can make
Obtain bloop 111 and effectively eliminate a part of noise, but also so that the volume of sound-absorbing material is suitable, can effectively absorb
Noise.
As shown in Figure 2 and Figure 5, the thickness of quieter material 20 is from one end to the other side in increasing trend, and quieter material 20
The other end be positioned at the side of multiple bloop 111.Sound absorber can be improved in one end that so thickness of quieter material 20 is bigger
Material layout reliability on spiral case 10, and so that the noise reduction of sound-absorbing material 20 is preferable.
Spiral case assembly 100 according to embodiments of the present invention, by arranging multiple bloop 111 on spiral case 10, and is arranged
Cover the sound-absorbing material 20 of multiple bloop 111, so that noise is entered into by multiple bloops 111 in spiral case 10
In sound-absorbing material 20, and it is absorbed or reflected in sound-absorbing material 20, thus sound-absorbing material 20 can preferably reduce spiral case
Noise in 10, can improve the noise reduction capability of range hood, can promote the quality of range hood.
Range hood according to embodiments of the present invention, including the spiral case assembly 100 of above-described embodiment, this spiral case assembly 100 is permissible
It is arranged in the casing of range hood, for other structures of range hood, such as, the structure such as exhaust fume collecting hood, deflector, for
The known technology of those skilled in the art, is not described in detail in this.There is the range hood of the spiral case assembly 100 of above-described embodiment
