Detailed description of the invention
Being described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings.The embodiment described below with reference to accompanying drawing is illustrative of, it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.
Below with reference to the accompanying drawings range hood 100 according to this utility model embodiment is described in detail.
Range hood 100 according to this utility model embodiment may include that casing 10 and spiral case blower fan 20.In conjunction with shown in Fig. 1 and Fig. 3, spiral case blower fan 20 is located in casing 10, and spiral case blower fan 20 has spiral case air inlet 21, and spiral case air inlet 21, towards the front side wall 14 of Fan casing 10, has the exhaust gases passes 11 connected with spiral case air inlet 21 in casing 10.Wherein, exhaust gases passes 11 is arranged between the front side wall 14 of casing 10 and spiral case air inlet 21.
Wherein, as shown in figures 1 and 3, casing 10 is integrally formed with cowling panel 12 on the sidewall of spiral case air inlet 21.Specifically, the front side wall 14 of the above-mentioned casing 10 sidewall towards spiral case air inlet 21 and casing 10.Alternatively, cowling panel 12 is by being stamped and formed out the front side wall 14 of casing 10.It is understood that the front side wall 14 of integrated casing 10 and cowling panel 12 simple in construction and intensity are high, it is possible to reduce cost and the manufacture difficulty of range hood 100.
According to an alternative embodiment of the present utility model, as shown in Figure 1-Figure 3, the bottom of casing 10 can be provided with exhaust fume collecting hood 30, and the top of exhaust fume collecting hood 30 has exhaust fume collecting hood air outlet 31, and exhaust fume collecting hood air outlet 31 connects with the lower end of exhaust gases passes 11.As it is shown in figure 1, the diapire of casing 10 is provided with exhaust fume collecting hood 30, exhaust fume collecting hood 30 is formed generally as the rectangular box structure of open at its lower end, and exhaust fume collecting hood air outlet 31 forms the roof at exhaust fume collecting hood 30 so that it is connected with exhaust gases passes 11.Alternatively, as shown in figures 1 and 3, spiral case blower fan 20 has motor 22, motor 22 and cowling panel 12 and is positioned at the top of exhaust fume collecting hood air outlet 31.
The operation principle of range hood 100 according to this utility model embodiment is described in detail below in conjunction with accompanying drawing.
When user cooks and opens range hood 100, flue gas on the kitchen range top is bottom-up to be flow in exhaust fume collecting hood 30, and flue gas flows in exhaust gases passes 11 by exhaust fume collecting hood 30, flue gas in exhaust gases passes 11 can be played rectified action by cowling panel 12, such that it is able to avoid the dispersion of flue gas, it is easy to flue gas flow direction spiral case air inlet 21, and cowling panel 12 can also avoid flue gas to be previously formed cyclone at entrance spiral case air inlet 21 at least to a certain extent, stream and noise, and then the wind loss of range hood 100 can be reduced and reduce the noise of range hood 100, the quality of range hood 100 can be improved.
The flue gas entered in spiral case blower fan 20 can separate under the centrifugal action of spiral case blower fan 20, and the cigarette after separation can be discharged from the air outlet casing 10, and the fluid after separation can flow to the lubricating cup of range hood 100 by dripping the mode assembled.
Range hood 100 according to this utility model embodiment, by cowling panel 12 being integrally formed on the front side wall 14 of casing 10, the wind loss of range hood 100 can be reduced on the one hand and reduce the noise of range hood 100, the quality of range hood 100 can be improved, cost and the manufacture difficulty of range hood 100 can be reduced on the other hand.
According to a preferred embodiment of the present utility model, as shown in figures 1 and 3, the relative spiral case air inlet 21 of cowling panel 12 is obliquely installed.Wherein, as it is shown on figure 3, the distance of plane is L1 residing for the upper end of cowling panel 12 and spiral case air inlet 21, residing for the lower end of cowling panel 12 and spiral case air inlet 21, the distance of plane is L2, wherein L1 < L2.In other words, the circulation area of exhaust gases passes 11 is gradually reduced from the lower end of cowling panel 12 to the upper end of cowling panel 12.Thus, the rectification effect of cowling panel 12 is better, and flue gas is easier to enter spiral case air inlet 21 place.
According to a specific embodiment of the present utility model, as it is shown on figure 3, the upper surface of cowling panel 12 extends above the top of the spiral case of spiral case blower fan 20, the lower surface of cowling panel 12 downwardly extends the bottom beyond spiral case.Wherein, cowling panel 12 width (i.e. the cowling panel 12 length on the left and right directions shown in Fig. 1) in the horizontal direction can be substantially the same with the radial dimension at spiral case air inlet 21 place.Thus, it is possible to make flue gas be rectified the effective rectification of plate 12, such that it is able to avoid cyclone, stream the generation with noise.
Preferably, cowling panel 12 can cover spiral case air inlet 21.In other words, cowling panel 12 width in the horizontal direction can more than the radial dimension at spiral case air inlet 21 place.It is to say, the projected area that cowling panel 12 is on the front side wall 14 of casing 10 is more than the spiral case air inlet 21 projected area on the front side wall 14 of casing 10.Thus, cowling panel 12 rectification effect is better, it is possible to is prevented effectively from cyclone, streams the generation with noise.
As in figure 2 it is shown, the recess 13 being formed in part with depression of corresponding cowling panel 12 on the front surface of sidewall.In order to improve the overall aesthetics of range hood 100, it is preferable that decoration (not shown go out) can be provided with in recess 13.Decoration can be effectively improved the cosmetic look of the front side wall 14 of casing 10, strengthens range hood 100 competitiveness commercially.
