Abstract
The utility model belongs to a jet type oil fume exhauster. Mainly solve the problem that current smoke ventilator purification rate is low and fan viscous oil. It is mainly characterized by that the fan blade is faced to the air inlet of the shell, under the fume-exhausting pipe an injection pipe is set, said injection pipe is connected with fan by means of pressure air channel, and the periphery of lower side of fume-collecting cover is equipped with oil-collecting groove. The oil fume is not in direct contact with the blades and the fan, is not sticky, and has the characteristics of low energy consumption and high oil fume exhaust rate. Only one 55-watt fan is used, the power consumption is reduced by more than 50% compared with the existing range hood, and the purification rate is improved to more than 85%.
Description
The utility model relates to a kind of smoke exhaust, particularly a kind of submerged jets formula smoke exhaust.
When existing smoke exhaust ventilator used, oil smoke must could be discharged from fume tube through blower fan, caused fan blade etc. to be stained with oil, must regularly clean, and blower fan is had certain infringement, and the mist extractor rate is not high, and only about 40%.
The purpose of this utility model is exactly to provide a kind of blower fan sticking oil, that power is not little, the mist extractor rate is high submerged jets formula smoke exhaust at above-mentioned weak point.
Technical solution of the present utility model is: a kind of submerged jets formula smoke exhaust, comprise oil extraction smoke pipe, centrifugal blower, shell, exhaust fume collecting hood, be located at the deep bead of both sides, exhaust fume collecting hood lower end, it is characterized in that: described centrifugal blower is located in the interlayer of the shell at top and exhaust fume collecting hood, the air inlet of centrifugal blower on shell, be provided with playpipe below the oil extraction smoke pipe, this playpipe links to each other with centrifugal blower through the pressure air channel.Around the bottom of exhaust fume collecting hood, be provided with oil trap.
Playpipe in the utility model technical solution can be one.
Playpipe in the utility model technical solution also can be for more than two.
Playpipe group end mouth in the utility model technical solution is that staged is arranged.
Be provided with diffuser between front shell in the utility model technical solution and the exhaust fume collecting hood.
The utility model is not because with the air inlet of centrifugal blower towards shell, oil smoke directly contacts with blade and blower fan, and therefore, blower fan is sticking oily.Because adopt playpipe, the wind that centrifugal blower is drawn into sprays from playpipe, the formation jet can entrainment oil smoke rapidly and from the discharge of oil extraction smoke pipe, the mist extractor rate improves greatly, the corresponding reduction of power.When injection pipe end mouth becomes staged to arrange, the mist extractor better effects if.Owing to be provided with diffuser, can discharge cool breeze in summer, lower the temperature to the operator.Since be provided with illuminating lamp, easy to use at night.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the utility model structural representation, and as Figure of abstract;
Fig. 2 is the right TV structure schematic diagram of the utility model.
The utility model is described in further detail below in conjunction with accompanying drawing: as shown in Figure 1 and Figure 2, oil extraction smoke pipe 1 passes shell 2 and directly is connected with exhaust fume collecting hood 3.Centrifugal blower 10 is fixed between shell 2 and the exhaust fume collecting hood 3, and centrifugal blower is towards the air inlet of shell 2, and blower fan 10 is provided with air inlet guard 15.Be provided with pressure air channel 8 in the shell 2, playpipe 4 is connected with pressure air channel 8, and playpipe 4 is three jet pipes, also can be many, forms direct projection pipe group, and the end mouth is that staged is arranged, and has and entrainments and the injection function.Be provided with oil trap 6 around shell 2 belows.Both sides, shell 2 below are provided with deep bead 7, can aspirate oil smoke effectively, and purifying rate is doubled than the various smoke exhaust ventilators that occur on the market at present.Shell 2 fronts are provided with cool breeze diffusing opening 5, in be provided with diffuser 11.Also be provided with illuminating lamp 9,13 on the shell 2, electric switch 12, hanger 14.The utility model has only used one 55 watts blower fan 10, compares with the smoke exhaust ventilator of selling on the market, and power consumption descends more than 50%, and purifying rate is brought up to more than 85%.
