Abstract
The utility model relates to a domestic cooker hood which comprises a machine cover, an electrical motor, an impeller, a spiral casing and an air accumulation disc which is provided with a main air outlet. The utility model is characterized in that an air storage cover is arranged between the air accumulation disc and the spiral casing; the periphery of the air storage cover is fixedly arranged on the air accumulation disc; the surrounding of the main air outlet on the air accumulation disc is provided with at least three auxiliary air outlets; the auxiliary air outlets is directly communicated with the air storage cover; the internal diameter of the air outlet on the air storage cover and the internal diameter of an air inlet on the spiral casing are both bigger than the outer diameter of the main air outlet on the air accumulation disc. The utility model is suitable for various kinds of cooking in families.
Description
The utility model relates to a kind of smoke exhaust ventilator.
The characteristics of single hole smoke exhaust ventilator are that impeller is big, and exhaust air rate is big, and flue gas velocity is fast, but are characterized in that the gas collection area is little.And the characteristics of diplopore smoke exhaust ventilator are that seizure oil smoke area is big, but because spatial constraints, impeller can not be too big, and the exhaust air rate in each hole and ventilation velocity all descend to some extent.
In view of above problem, the purpose of this utility model provides that a kind of ventilation velocity is fast, and exhaust air rate is big, catches the also big household smoke exhaust ventilator of oil smoke area.
For achieving the above object, the utility model adopts following design: a kind of household smoke exhaust ventilator, comprise hood, motor, impeller, spiral case and gas collection dish with main air outlet, it is characterized in that: a storage cover is set between described gas collection dish and spiral case, be fixed on the described gas collection dish around the described storage cover, auxiliary air outlet more than at least two is set around the described gas collection dish master air outlet, described auxiliary air outlet leads directly to described storage cover.The air outlet internal diameter of described storage cover and the air inlet internal diameter of spiral case are all greater than the main air outlet external diameter of described gas collection dish.
The utility model is owing to taked auxiliary air outlet of increase and the design that increases storage cover on the gas collection dish, when wheel rotation, in the negative pressure that gas collection dish air outlet one side produces, make and discharge outdoor rapidly by the gap of oil smoke between gas collection dish and storage cover of assisting air outlet to enter storage cover.So not only kept single hole lampblack absorber impeller big, exhaust air rate is big, and the advantage rapidly of discharging fume keeps again and the oil smoke that increased the diplopore smoke exhaust ventilator is caught area.It is power saving both, and noise is again little.Through test, resultant effect is than single, and diplopore smoke exhaust ventilator effect is all good.It can be widely used in the cooking of various families.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is upward views of accompanying drawing 1.
As shown in Figure 1: motor 1 is screwed on hood 2, and impeller 3 rotations.Spiral case 4 covers on impeller 3 outsides, and is screwed with hood 2.Have a main air outlet 6 and four auxiliary air outlets 7 on the gas collection dish 5.A storage cover 8 covers on above the gas collection dish 5, is screwed with gas collection dish 5 around the storage cover 8, and the internal diameter of the air outlet 9 of storage cover 8 is greater than the external diameter of the gas collection dish 5 main air outlets 6 that are mated.The internal diameter of same spiral case 4 air inlets 10 is also greater than the external diameter of gas collection dish 5 main air outlets 6.Four auxiliary air outlet 7 straight-through storage covers 8 on the gas collection dish 5.Be screwed with casing 2 around gas collection dish 5 bottoms.
In the foregoing description, the quantity of auxiliary air outlet also can be two or other quantity, but the designing optimal of four auxiliary air outlets.
In the foregoing description, the structure of each parts and connecting mode all can adopt other form, also can adopt other forms such as axial flow such as the structure of impeller.
In the time of operation, the rotation of impeller in the caused negative pressure of a side of gas collection dish air outlet, makes the oil smoke of main air outlet and discharges outdoor rapidly by the oil smoke that auxiliary air outlet enters in the storage cover.Especially the oil smoke that directly jumps on the gas collection dish when choking pot or fried food can not hit, and effect is especially remarkable.
Claims (1)
1, a kind of household smoke exhaust ventilator, comprise hood, motor, impeller, spiral case and gas collection dish with main air outlet, it is characterized in that: a storage cover is set between described gas collection dish and spiral case, be fixed on the described gas collection dish around the described storage cover, auxiliary air outlet more than at least two is set around the described gas collection dish master air outlet, described auxiliary air outlet leads directly to described storage cover, and the main air outlet internal diameter of described storage cover and the air inlet internal diameter of spiral case are all greater than the main air outlet external diameter of described gas collection dish.
