Abstract
The utility model relates to an air inlet and air-flue structure of a range hood, which aims at improving the efficiency of the range hood, reducing the diffusion of the oil smoke and the waste gas after being burned, so that the oil smoke and the waste gas can be away from the cook. The air inlet and air-flue structure consists of a plurality of independent air inlet units and air flues, and a throttling part, a check valve and a pipeline which are arranged inside the air flue. Through the position variation of the air inlets on each air inlet unit and the flow-rate sub-pressure adjustment of the airflow at each air inlet by the throttling part, the air inlets of the range hood can be arranged to be close to the opening and the cooking utensils as far as possible so as to guide the oil smoke and waste gases to be away from the cook, thereby preventing the rang hood from interfering the flame stability of the cooking utensils while improving the efficiency of the range hood.
Description
Technical field
The utility model relates to a kind of smoke exhaust ventilator air inlet and air channel structure, more particularly just relate to a kind ofly can improve smoke pumping efficient, reduce oil smoke and the waste gas diffusion of burning back and make oil smoke and waste gas away from the novel cooking fume exhauster air inlet and the air channel structure of cooker.
Technical background
Existing smoke exhaust ventilator is because air inlet quantity is single, and air inlet can't effectively solve diffusion, escape and the decline problem of oil smoke in uphill process from reasons such as the source of oil smoke source and burnt gas distance are far away, and it is lower to cause aspirating oil smoke efficient.Inhale the power of fan that excellent oil smoke efficient improves lampblack absorber for improving, DeGrain but can cause negative consequences such as noise and power consumption increase.And other are integrated in the lampblack absorber on the kitchen range kitchen range top, and its position, inlet scoop is below pan, though its inlet scoop, is also deposited the shortcoming that pumping airflow influences kitchen range flame holding and waste heat energy than the more close pan of conventional lampblack absorber.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of smoke exhaust ventilator air inlet and air channel structure.
The utility model is achieved by following technical proposals.
The utility model comprises a plurality of independently air inlet groups and air channel, and the throttle part, check-valves and the pipeline that are installed in the air channel are formed.
A plurality of independently air inlets vertically are combined into an air inlet group, and respectively independently air inlet changes successively apart from the distance of cooker in the horizontal direction, and a lampblack absorber has a plurality of air inlet groups.Each air inlet connects an independently air channel, by being installed in the throttle part in the air channel, can be under the effect of bleeding of same blower fan, and the bleed negative pressure and the flow size of regulating each air inlet in the air inlet group respectively.All air channels of same air inlet group pool an air channel in lampblack absorber inside, a check-valves is installed.By the folding of check-valves, can when using same blower fan, switch the duty of each air inlet group.
Good effect of the present utility model is, can reduce the distance of lampblack absorber air inlet to the full extent apart from kitchen range and pot, by each independent air intake mouth of reasonable arrangement different bleed negative pressure and rate of air sucked in required, under the situation that does not influence the kitchen range flame holding, can take out more kitchen range burnt gas and oil smoke, also can guide oil smoke and waste gas away from cooker simultaneously.
Description of drawings
Be described further this use is novel below in conjunction with accompanying drawing.
Fig. 1 is the front view of the utility model structure.Fig. 2 is the left view of the utility model structure.
Among the figure, 1. lampblack absorber shell, 2. air inlet group, 3. check-valves, 4. throttle part, 5. pipeline.The concrete shape of each parts and quantity only play the signal effect in the accompanying drawings, and each component shape shown in the figure and quantity are not essential features.
The specific embodiment
The utility model comprises the air inlet group 2 that is installed in the lampblack absorber shell 1, check-valves 3, lampblack absorber air inlet and air channel structure that throttle part 4 and various pipeline 5 are formed.
Lampblack absorber of the present utility model has a plurality of air inlet groups of being made up of the air inlet of vertical arrangement 2.The concrete quantity of air inlet group 2 can be two, more than three or three.The particular location of air inlet group 2 can be over against kitchen range top stove eye, also can be placed in stove eye both sides, to surround the stove eye.Each air inlet that comprises in the air inlet group 2 is connected with throttle part 4 by pipeline 5.Described throttle part 4 is various choke valves or capillary, by adjusting to each throttle part 4, and can be so that each air inlet has different rates of air sucked in required and negative pressure value.As shown in Figure 1, each air inlet of same air inlet group 2 and the distance between the cooker can be so that the as close as possible pan of the air inlet of smoke exhaust ventilator and the kitchens range top successively by curvilinear motion.Can allow smoke exhaust ventilator before oil smoke and kitchen range burnt gas diffusion escape, it be sucked in smoke exhaust ventilator air inlet, have very high pumping-clean rate.And the throttle part 4 that each air inlet connected can be controlled the rate of air sucked in required and the negative pressure value of corresponding air inlet; can effectively prevent to disturb when smoke exhaust ventilator from bleeding the stability of kitchen range flame; and guide oil smoke and kitchen range burnt gas away from cooker, the health of protection cooker.
Each throttle part 4 in belonging to an air inlet group 2 is connected with check-valves 3 by pipeline 5.By the switching of control check-valves 3, whether this air inlet group 2 bleeds when being controlled at the fan operation of smoke exhaust ventilator.
Claims (5)
