Abstract

The utility model relates to a window cooking fume exhauster, which is a device used for exhausting the cooking fume in the kitchen. The utility model is composed of a spiral casing, an air intake tube, an air intake hood, an air exhaust tube, two supporting frames, a bottom plate, a filter screen and an oil receiving box, an air exhaust impeller and an electric motor are arranged in the spiral casing, the spiral casing, the air intake tube, the air intake hood, the two supporting frames and the bottom plate are assembled into a whole body, the whole body is arranged on the window stand in the kitchen, and the air exhaust port of the spiral casing is inserted in the air exhaust tube fixed on the window. The utility model has the advantages that the cooking fume exhausting efficiency is high, the cooking fume in the kitchen can be exhausted rapidly, the utility model is not needed to be disassembled and cleaned, only one electric motor is needed, compared with the common cooking fume exhauster, the electric power can be saved by 50%, the structure is simple, the cost is low, and the utility model can be manufactured by common manufacturers.

Description

Window formula smoke exhaust ventilator

The utility model relates to a kind of device that extracts kitchen fume effectively.

The hanging smoke exhaust ventilator of Xiao Shouing all has two impeller motor groups in the market, is shaped as squarely, places on the height of about 80 centimetres of cooking stove tops.The exhaust resistance of lampblack absorber own is big, if ventilating opening exhaust between the kitchen, then resistance is bigger.Though two exhausting impellers are set, the smoke pumping ability is still not enough, and indoor when cooking to still have some oil smoke to take out unclean.Room noise is bigger, makes the people be difficult to bear.At least unpick and wash once every year, very is trouble.

Follow-on cabinet type smoke exhaust ventilator relatively can extract indoor oil smoke effectively, but cook the food inconvenient operation, often needs wiping cabinet wall and table.Big and unpick and wash once at least every year with the same workplace noise of hanging smoke exhaust ventilator.

The purpose of this utility model provide a kind of efficient, exempt to unpick and wash, power saving and the little window formula smoke exhaust ventilator of noise.

The purpose of this utility model is achieved like this: window formula smoke exhaust ventilator is made up of spiral case, exhausting impeller, motor, swab case etc.Exhausting impeller and the motor that is complementary are contained in the spiral case, be plugged with an air induction mast on the air inlet of spiral case, air induction mast one side has a strip air inlet, is fixed with an airscoop shroud at strip air inlet place, and insert in the gas outlet that is fixed on the window gas outlet of spiral case.

The utlity model has following advantage:

1. be side direction type owing to the exhausting mode, and lower apart from the height of boiler face, thus smoke pumping efficient height, can all take the oil smoke that produces when cooking food rapidly away, improved operating personnel's working environment.

2. the long-term use of this window formula smoke exhaust ventilator need not unpicked and not washed.A mist of oil filter screen is equipped with at air induction mast air inlet place, and sticking oil flows in the air induction mast on oil that filter screen leaches and the airscoop shroud, and tubule flows in the swab case by draining the oil.The gas oil content that enters the exhausting impeller is few, and certain temperature is arranged, and does not accumulate greasy filth on the impeller, and it is outdoor that a little thin oil flows into the gas outlet discharge in the spiral case.

This window formula smoke exhaust ventilator have only one with on the market the suitable motor of smoke exhaust ventilator power, therefore, economize on electricity 50%.

4. this window formula smoke exhaust ventilator intake and exhaust resistance is little, and the air inlet place has filter screen can reduce impeller air inlet wave reflection, and therefore, the noise of generation is less, and recording noise in 2 meters distant places of distance stove is 61 decibels.

5. the ventilating opening three on the wall constitutes a variable cross-section chimney system between the gas outlet of this window formula smoke exhaust ventilator, kitchen and between the kitchen, finishes after meal, shuts backstairs, can realize the gravity-flow ventilation ventilation between the kitchen, takes the residual gas between the kitchen away.

6. simple in structure, production cost is low, is fit to general manufacturer production.

Be described further below in conjunction with two pairs of the utility model of figure one, figure.

Figure one is the vertical view of this smoke exhaust ventilator, and figure two is A-A cutaway views of figure one.

1. spiral cases, 2. impellers, 3. air induction masts, 4. airscoop shrouds, 5. filter screens, 6. gas outlets, 7. supports, 8. base plates, 9. swab cases among the figure.

This window formula smoke exhaust ventilator by spiral case 1, impeller 2, air induction mast 3, airscoop shroud 4, filter screen 5, gas outlet 6. support 7, base plate 8 and swab case 9 are formed.Impeller 2 and the motor that is complementary are contained in the spiral case 1, air induction mast 3 of grafting on the air inlet of spiral case 1, one side of air induction mast 3 is opened a strip air inlet, fixes an airscoop shroud 4 at strip air inlet place, and insert in the gas outlet 6 that is fixed on the window gas outlet of spiral case 1.Spiral case 1, air induction mast 3, airscoop shroud 4, support 5 and base plate 8 form a whole, and place on the window sill between the kitchen.Mist of oil filter screen 5 is equipped with at strip air inlet place at air induction mast 3, and the oil of filtering flows in the air induction mast 3, and tubule flows in the swab case 9 through draining the oil.

Connect startup power supply, impeller 2 clockwise directions rotations (figure two).The oil smoke that produces when cooking rises, and mixes with indoor horizontal flow air (at this moment backstairs remain on out state), and gaseous mixture in airscoop shroud 4 inflow air induction masts 3, enters in the atmosphere through impeller 2, spiral case 1 and gas outlet 6 under the swabbing action of impeller.

Claims

1. window formula smoke exhaust ventilator, comprise spiral case, exhausting impeller, motor, swab case, exhausting impeller and the motor that is complementary are contained in the spiral case, it is characterized in that, be plugged with an air induction mast on the air inlet of spiral case, air induction mast one side has a strip air inlet, is fixed with an airscoop shroud at strip air inlet place, and insert in the gas outlet that is fixed on the window gas outlet of spiral case.
