Below with reference to Fig. 1-Fig. 8 description according to the side extraction cooking fume extractor 100 of the utility model embodiment.

It should be noted that side extraction cooking fume extractor holds together the problem of cigarette area deficiency to make up top, on the downside of inclined-plane It is closer apart from cooking apparatus, it is easy to occupy cooking space because complete machine depth is bigger than normal, influences user's operation experience.And smoke machine is whole Machine depth (referring to the size of smoke machine in the longitudinal direction) is bigger than normal, and family is difficult to be encompassed completely in locker when installing.Such as Shown in the kitchen installation effect diagram of the general side extraction cooking fume extractor of Fig. 1, row's locker is installed above hearth, to keep away Exempting to meet and discuss locker usually will not be too deep.But general side extraction cooking fume extractor, since depth is excessive, locker is at smoke machine It can not install, kitchen whole style is difficult to coordinate at smoke machine.

And the side extraction cooking fume extractor 100 of the utility model embodiment, it is designed, is pursued under smaller air quantity by optimizing flow passage Complete machine depth can be contracted to be less than or equal to 350mm by dead-tight smoke absorption effect.The utility model as shown in Figure 2 is implemented Baffle can be arranged in the front side of side extraction cooking fume extractor 100 in the kitchen installation effect diagram of the side extraction cooking fume extractor of example 210, baffle 210 is mutually unified in appearance with the locker 200 on side, and such kitchen whole style can be coordinated.This is practical In the novel embodiment having, the complete machine height of side extraction cooking fume extractor 100 is less than or equal to 560mm, this smoke machine bottom after mounting Portion will not expose below baffle 210, or even entire smoke machine can be encompassed completely in locker 200, and kitchen aesthetics is more preferably. Smoke machine is designed depth, highly smaller, the avoidable operating experience for influencing user.

In the present invention by CFD runner calculation method, air-inlet grille 2 can be optimized, oil smoke can Preferably to enter casing 1 by air inlet hole 21, reinforce holding together cigarette effect and improving fume-exhausting efficiency for range hood, and then realize The miniaturization of smoke machine.

Concrete principle is as follows:

Oil smoke is rendered as a kind of diffusion type propradation in uphill process, the path risen according to oil smoke and set machine Air-inlet grille 2 is arranged in 1 contour structures of shell, simplifies the path that oil smoke leads to suction inlet 31, reduces the escape of oil smoke, to realize same Efficient smoke pumping effect under air quantity.

Air-inlet grille 2 can carry out area distributions in optimization position section according to suction inlet area section after optimization, not office It is limited to certain specific modelling.

Air-inlet grille 2 can solve blower in the case where optimal inlet -duct area by adjusting the area distributions of air-inlet grille 2 Suction unevenness problem in left and right caused by the placement position of 3 outlet 32.

The offset or dish of 2 place plane of air-inlet grille and 31 place plane of suction inlet can change with level and adjust.

As shown in Figure 3 and Figure 4, according to the side extraction cooking fume extractor of the utility model embodiment 100, including casing 1 and wind Machine 3.The side view of casing 1 be approximately it is inverted trapezoidal, the front panel 11 of casing 1 tilts backwards setting in a downward direction, Front panel 11 is equipped with air-inlet grille 2, and air-inlet grille 2 has multiple air inlet holes 21, and the top of casing 1 is equipped with air outlet 12.

Blower 3 is equipped in casing 1, blower 3 is centrifugal blower.The suction inlet 31 of blower 3 is arranged towards front panel 11, blower 3 Outlet 32 be connected with air outlet 12.

The size of side extraction cooking fume extractor 100 in the longitudinal direction is less than or equal to 350mm, the plane where air-inlet grille 2 The range of tilt angles in opposed vertical face is 20 degree~50 degree.

Here, suction can be generated after blower 3 rotates at suction inlet 31, external flue gas is passed through into the air inlet on air-inlet grille 2 Hole 21 sucks in casing 1.After flue gas in casing 1 is involved in compression by blower 3, it is discharged by the air outlet 12 on casing 1.It is cooking During cooked food, oil smoke is rising upwards, and the front panel 11 being obliquely installed can increase and the contact of upward rising oil smoke Area, thus oil smoke can more large area contacted with air-inlet grille 2.Air-inlet grille 2 has multiple air inlet holes 21, and oil smoke is along multiple Air inlet hole 21 enters in casing 1, and then oil smoke can continue rising in phase.Air outlet 12 is located at the top of casing 1, is conducive to oil Cigarette dissipates upwards out of casing 1, and then improves the smoke exhaust efficiency of side extraction cooking fume extractor 100.Air-inlet grille 2 can intercept big portion The smoke particle divided guarantees smoke machine service life, while can also reduce other cooking-fume discharging, protects environment.

Since the size of side extraction cooking fume extractor 100 in the longitudinal direction requires to be less than or equal to 350mm, the inside of casing 1 Space is smaller, is smoked using centrifugal blower, is just that the impeller 34 of centrifugal blower is utilized is flat with respect to having for other impellers The feature of graduation, and centrifugal blower air draught power is strong, can guarantee that small body smoking has enough power.Centrifugal blower is in casing 1 Interior position adjustment space is limited, and the suction inlet 31 of blower 3 makes suction inlet 31 of the external flue gas towards blower 3 directly against air-inlet grille 2 Sucking.Cooperation makes small depth smoke machine have optimal smoking effect with the tilt angle of air-inlet grille 2.Made using air-inlet grille 2 For import, air intake resistance is smaller, and air inlet path is short, low noise.

In addition, the side view of casing 1 to be arranged to approximate inverse is trapezoidal, the back side of casing 1 is almost pacified in close to wall Dress, body entirety center of gravity is closer apart from wall, and the moment of flexure of generation is smaller, and installation is steady.Since the depth dimensions of casing 1 are by larger Limitation, therefore casing 1 is arranged to trapezoidal, it advantageously ensures that 1 inner space capacity of casing, avoids the flue gas in casing 1 because of wind Machine 3 is taken away not in time and is nowhere buffered.

Certainly, the side extraction cooking fume extractor 100 of the utility model embodiment can according to need configuration flue and noise elimination portion Part (not shown go out).When side extraction cooking fume extractor 100 configures flue, flue connects the top of casing 1 and connects with air outlet 12 Logical, flue is used to for flue gas being discharged kitchen, and the height of flue is here with no restriction.Muffler part can be set in casing 1, machine Muffler part can be respectively provided in shell 1 and flue.

According to the side extraction cooking fume extractor 100 of the utility model embodiment, set 1 shape of casing, air-inlet grille 2 incline Rake angle design, designs the optimal path of oil smoke rising, it is possible to reduce the loss of local eddy currents reduces noise, promotes complete machine Working efficiency reaches few leakage cigarette even zero leakage cigarette effect under identical air quantity.By effectively by complete machine depth foreshorten to 350mm with It is interior, keep complete machine structure appearance clean and tidy, brief, some can be even hidden in inside locker, realize side extraction cooking fume extractor 100 Miniaturization, readily available biggish cooking space.In addition, machine volume can also reduce, manufacturing cost, installation difficulty can all drop It is low.

Optionally, the on-link mode (OLM) of air-inlet grille 2 and casing 1 is removably, to realize the quick of air-inlet grille 2 Dismounting is also beneficial to dismounting blower 3.For example, air-inlet grille 2 can snap connection on plate 11 in front；Air-inlet grille 2 can be with one End is hingedly connected on casing 1, other end bolt or is snapped connection on casing 1.Certainly, the air inlet of the utility model embodiment The connection type of grid 2 is without being limited thereto, such as air-inlet grille 2 can be fixedly connected on front panel 11 or even air-inlet grille 2 one Body is formed on plate 11 in front, and front panel 11 is openable and closable structure on casing 1.

Specifically, as shown in Figure 3 and Figure 4, blower 3 includes: spiral case 33, impeller 34, motor 35 and exhaust air flue 36, spiral case 33 are located in casing 1, and spiral case 33 has suction inlet 31, and suction inlet 31 is located at the front side of spiral case 33 and is arranged towards air-inlet grille 2.Outlet air Air duct 36 is connected on spiral case 33, and the upper end of exhaust air flue 36 constitutes outlet 32 and is connected with air outlet 12 on casing 1.Impeller 34 It is located at spiral case 33, motor 35 is mounted on the rear portion of spiral case 33.

In some embodiments of the utility model, as shown in figure 4, the 34 place face opposed vertical face of impeller of blower 3 Range of tilt angles is between 0 degree~25 degree, and 34 place face of impeller and the rotation axis of blower 3 are perpendicular.That is, impeller 34 places face can be vertically arranged, can also be equally obliquely installed with the front panel 11 of camera shell 1.But in order to generate upwards backward Suction roll up power, and also for guarantee complete machine depth foreshorten within 350mm, the 34 place face opposed vertical face of impeller of blower 3 Range of tilt angles preferably between 0 degree~25 degree.

In the example of fig. 4, when the inclination in 34 place face opposed vertical face of impeller, spiral case 33 is also required to be obliquely installed, And exhaust air flue 36 be it is vertically arranged, guarantee smoke path it is most short.
