The edge of mouth 118 is relative, the connection of Oil Guide portion 182 oil collecting ring 180, angle formed by the axial A5 in positioning side 178 and Oil Guide portion 182
It is 10 °~60 ° to spend θ scopes.Thus, oil collecting ring 180 collects the greasy dirt or water flowed out through smoke inlet 118, greasy dirt or water are through leading
Oily portion 182 flows to the oil trap installed in the position that range hood 100 is specified, such as housing 102 on rear support bar 184 and (schemed not
Show) in.
In some instances, θ=10 °, 20 °, 25 °, 30 °, 45 °, 50 ° or 60 °.
In addition, the steam that the spray orifice 146 that above-mentioned angular range is jet pipe 112 sprays is ejected on the blade of impeller 116 preferably
Angular range.When mounted, the position of one of them in the axial A5 and positioning side 178 in Oil Guide portion 182 can be first determined,
Then another position is determined further according to above-mentioned angular range.
Specifically, oil collecting ring 180 and Oil Guide portion 182 can be made of plastics, and oil collecting ring 180 and Oil Guide portion 182 can be
Integrated formed structure.Thus, the cost in oil collecting ring 180 and Oil Guide portion 182 is relatively low, and good airproof performance, not easy oil leakage dirt or water.
In embodiment of the present invention, the quantity in oil collecting ring 180 and Oil Guide portion 182 is two, each oil collecting ring 180 with corresponding one
The edge of smoke inlet 118 is relative.Oil Guide portion 182 is in strip.
In some embodiments, Figure 12 please be join, steam generator 110 includes heater 184, water pump 186 and connecting tube
Road 188, the connection heater 184 of connecting pipe 188 and water pump 186, heater 184, connecting pipe 188 and the common structure of water pump 186
Into U-shaped arrangement.Thus, the space shared by steam generator 110 is less, thin fume extractor 100 is advantageously implemented.
Specifically, in the example depicted in fig. 12, steam generator 110 includes shell 190, heater 184 and water pump 186
In shell 190, the entrance point 192 of heater 184 wears shell 190, and entrance point 192 passes through inlet channel 130 and cup
108 connections, the port of export 194 of water pump 186 is connected by the first segment pipe 136 with the import of threeway 142.Heater 184 can be
Electric heating body.In the present example, the port of export 194 of water pump 186 is used as the steam (vapor) outlet end of steam generator 110, steam
The steam (vapor) outlet end of generator 110 offers the steam (vapor) outlet of steam generator 110.
When steam cleaning device 106 works, water pump 186 is pumped into water from cup 108, and the heating water of heater 184 forms steam,
Finally sprayed from jet pipe 112, impeller 116 is cleaned.
