Specific embodiment
Embodiments of the invention are described below in detail, the example of described embodiment is shown in the drawings, wherein from start to finish
The element that same or similar label represents same or similar element or has same or like function.Below with reference to attached
The embodiment of figure description is exemplary it is intended to be used for explaining the present invention, and is not considered as limiting the invention.
The exhaust fume collecting hood 10 for lampblack absorber 100 of embodiment according to a first aspect of the present invention is described below with reference to Fig. 1-Fig. 9.
Here, the exhaust fume collecting hood 10 for lampblack absorber 100 can be used for dust catcher, when exhaust fume collecting hood 10 is used for dust catcher for dust catcher
Dust gathering arrester.
As shown in figure 1, the exhaust fume collecting hood 10 for lampblack absorber 100 of embodiment according to a first aspect of the present invention, including：Casing
11, define air-inlet cavity 1102 in casing 11, casing 11 is formed with air inlet and air outlet 1101, air inlet and air outlet
1101 are all connected with air-inlet cavity 1102, and the wind-guiding direction of air inlet is in predetermined angle with the wind-guiding direction of air outlet 1101；?
That is, when air-flow flows into air-inlet cavity and flows out from air outlet from air inlet, positioned at air flow direction and the position of air inlet position
On the no longer same straight line of air flow direction of air outlet 1101 position.For example as shown in figure 1, the wind-guiding direction (air-flow of air inlet
Flow direction) it is direction from the bottom up, the wind-guiding direction (air flow direction) of air outlet 1101 is direction from left to right, now air intake
The wind-guiding direction of mouth and the angled setting in wind-guiding direction of air outlet 1101, so, the air-flow entering from air inlet will not be direct
Ground passes along direction from the bottom up from air outlet 1101, but needs to change flow direction, as such, it is possible to make folder in air intake air-flow
Miscellaneous oil smoke or dust more rest in air-inlet cavity 1102, thus, it is possible to avoid oil smoke or dust to enter from air outlet 1101
Enter in exhaust passage, it is to avoid oil smoke or dust adsorption accumulate on blower fan or motor and affect its normal work.
Advantageously, as shown in figs. 7 to 9, the inwall of casing 11 is formed with the guiding gutter 111 extending to air inlet.Oil smoke
, during using, because oil smoke is constantly inhaled in air-inlet cavity 1102, the smoke particle carrying in oil smoke is continuous for machine 100
Ground accumulates on the inwall of casing 11, and by arranging guiding gutter 111, guiding gutter 111 can be by the oil of absorption on casing 11 inwall
Drip and converge, and greasy dirt is guided to air inlet discharge, the feculence box that user can be connected with air inlet by periodic cleaning the most at last
16, the dirty oil that cleaning is collected, thereby may be ensured that the cleaning in kitchen, it is to avoid dirty oil is made dirty the kitchen range top or ground.Additionally, passing through
Setting guiding gutter 111, can improve the collection efficiency to the oil droplet on casing 11 inwall, reduce the oil residues on casing 11 inwall
Drip, such that it is able to improve the cleaning performance to casing 11.
In addition, when cleaning exhaust fume collecting hood 10 and being clear, the cleaning solution in air-inlet cavity 1102 and greasy dirt all can pass through guiding gutter
111 drain in the feculence box 16 being connected with air inlet, and now, user can take off feculence box 16, outwells dirty water, such that it is able to
Dirty washings during cleaning lampblack absorber 100 are avoided to make dirty the kitchen range top or ground.
Exhaust fume collecting hood 10 for lampblack absorber 100 according to embodiments of the present invention, is led by arranging on the inwall of casing 11
Chute 111, it is possible to use guiding gutter 111 water conservancy diversion is gathered in the greasy dirt on casing 11 inwall, be easy to spot or cleaning fluid following current and
In the feculence box of lower entrance bottom, such that it is able to improve the collection efficiency to the oil droplet on casing 11 inwall, reduce casing 11 inwall
On entrained oil droplet.
In some embodiments of the invention, as shown in Figure 7 and Figure 8, guiding gutter 111 can include multiple, multiple water conservancy diversion
Groove 111 can be along the circumferential uniform intervals arrangement of casing 11 inwall, thus, it is possible to increase the receipts to greasy dirt on casing 11 inwall
Collection, reduces the residual of the greasy dirt on casing 11 inwall.
Advantageously, with reference to Fig. 7 and Fig. 8, the bearing of trend perpendicular to guiding gutter 111 of guiding gutter 111 (institute in such as Fig. 7
The above-below direction showing) cross section can U-shaped, V-type or semicircle, thus, it is possible to being processed in order to guiding gutter 111
Type, improve production efficiency.Further, it is also possible to the oil droplet being easy on casing 11 inwall flows to water conservancy diversion by the side wall of guiding gutter 111
In groove 111, thus realizing greasy dirt converges and flows backward to air inlet discharge.
In some embodiments of the invention, air inlet position can be provided with filter 12, and filter 12 can seal
Lid air inlet, and filter 12 collectively defines air-inlet cavity 1102 with casing 11.When lampblack absorber 100 works, the oil of outside
Cigarette first passes through after filter 12 tentatively filters and enters back in air-inlet cavity 1102, thus, it is possible to realize initial gross separation oil smoke
Effect, reduces oil smoke or the dust entering in air-inlet cavity 1102, thus reducing the greasy dirt in air-inlet cavity 1102 or dust accumulation.
Advantageously, filter 12 can include linkage section 121 and extension 122, one end (such as Fig. 2 of linkage section 121
Shown in linkage section 121 lower end) with week of air inlet along being connected, and at least a portion of linkage section 121 from periphery edge to
Inner edge is inclined upwardly that is to say, that at least a portion of linkage section 121 is in the wind-guiding direction (institute in such as Fig. 2 along air inlet
The direction from the bottom up showing) on the radially tapered taper of size, the other end of extension 122 and linkage section 121 (for example schemes
The upper end of the linkage section 121 shown in 2) it is connected, and linkage section 121 and extension 122 are respectively positioned on the inner side of casing 11, linkage section
121 can be in the cylindrical shapes of the wind-guiding direction extension along air inlet, and the upper end of linkage section 121 is closed by cleaning device 15.By
This, can increase the area of air inlet, improves the suction efficiency to oil smoke for the air inlet, reduce the loss of air inlet oil smoke, make
The structure obtaining filter 12 is simpler rationally.
Preferably, as shown in figs. 7 to 9, the side perisporium relative with air-inlet cavity 1102 of filter 12 can be formed
There is oil guide groove 1202, oil guide groove 1202 extends along the axis (above-below direction for example shown in Fig. 8) of filter 12, and Oil Guide
The axis that groove 1202 can be included around filter 12 is spaced apart multiple.Inlet chamber interior suction is attached to the week of filter 12
Greasy dirt on wall can be guided to air inlet by oil guide groove 1202, thus, it is possible to improve on the perisporium to filter 12
The collection efficiency of oil droplet, reduces the entrained oil droplet on filter 12 perisporium.
In addition, when cleaning exhaust fume collecting hood 10 and being clear, the cleaning solution in air-inlet cavity 1102 and greasy dirt are all not only by machine
Guiding gutter 111 on shell 11 inwall drains in the feculence box 16 being connected with air inlet, can also be by filter 12 perisporium
Oil guide groove 1202 drain into feculence box 16, user can take off feculence box 16, outwells dirty water, such that it is able to avoid cleaning oil
During cigarette machine 100, dirty washings are made dirty the kitchen range top or ground.
Preferably, filter 12 can have open mode and closed mode, and filter 12, in open mode, enters
Wind chamber 1102 is connected with space outerpace, and now, outside oil smoke can enter air-inlet cavity by filter 12 and air inlet
In 1102, now, lampblack absorber 100 is smoke pumping state；When filter 12 in off position when, filter 12 can seal
Air inlet, now air-inlet cavity 1102 do not connect with space outerpace, and now lampblack absorber 100 can enter cleaning function, Ke Yixiang
Shower water and cleaning solution in air-inlet cavity 1102.
