Abstract
The utility model relates to a spiral suction type fume purifying machine which greatly improves the ventilator of the existing fume purifying machine. The spiral chamber of the original centrifugal fan is changed into a circular cylinder shape, and a wind inlet chamber and a wind outlet chamber are arranged in the spiral chamber. A spiral flow divider body is arranged between the wind inlet chamber and the wind outlet chamber, and the inlet wind and the outlet wind is divided. A step spiral dispersed-flow sheet is adopted for controlling the spiral of the wind in the room and avoiding the vortex flow, the wind direction of coming in from the lower part and going out from the upper part of the inlet wind is rapidly formed, and the structure and the wind outlet direction of the centrifugal fan is fundamentally changed. A fume purifying apparatus is also arranged in the cover casing of the spiral suction type fume purifying machine. Large quantity of pollutant can be stuck on a filter sheet in the fume purifying apparatus, and the purification efficiency is raised. The utility model can be widely used for the purification of the fume in the domestic kitchen.
Description
The utility model relates to the household kitchen cooking fume control equipment, specifically a kind of spiral suction-type smoke purifier.
At present, generally adopting axial fan or centrifugal fan in the kitchen oil fume purifier at home and abroad is power source.All there is certain weakness in these two kinds of blower fans, as: the pressure that axial fan produced is less, and noise ratio is bigger; The air outlet of centrifugal fan and air inlet direction are 90 °, and the exhaust outlet that is contained in the smoke purifier need upwards be made 90 ° zig zag again, just can receive outer bend pipe.Owing to through turning several times, make that pacing up and down appears in oil smoke gas in pipe, resistance strengthens, and pressure reduces, and has a strong impact on the emission effect of oil smoke gas, has increased the consumption of the energy simultaneously.So the effect that above-mentioned two kinds of blower fans are applied in the smoke purifier is all not ideal enough.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, a kind of smoke purifier of using spiral suction-type blower fan is provided, the direction that makes it air intake and air-out is identical, the inhalation power of soot gas is strengthened, thereby raising is to the emission effect of soot gas.
How introduce the purpose of this utility model below in conjunction with accompanying drawing realizes.
Fig. 1 is that cutaway view is looked on an overall structure of the present utility model left side.
Fig. 2 is propeller fan 3 internal structure front views of the present utility model.
Fig. 3 is propeller fan 3 internal structure vertical views of the present utility model.
Fig. 4 is the structure vertical view of cooking fume remover 2 of the present utility model.
Fig. 5 is the A-A cutaway view of Fig. 4.
The utility model is similar with existing smoke purifier, includes ventilation blower, exhaust fume collecting hood housing, lubricating cup, illuminating lamp, switch and power line and plug. The difference place is: its ventilation blower is a kind of new-type spiral suction type ventilation blower. In addition, in the exhaust fume collecting hood housing, also be provided with a cooking fume remover. The spiral suction type ventilation blower that adopts in the utility model is to have made significant improvement on the basis of former centrifugal fan. Its key point is: utilize fluid principles, adopt a whole set of spiral component that the volute structure of former centrifugal blower is improved, changed the air outlet direction of former centrifugal blower, make the air inlet/outlet direction consistent. By Fig. 2, shown in Figure 3, the volute of this spiral blower fan is formed by cylinder shell 6 encirclements of blower fan. Be nested with one in the periphery, bottom of housing 6 and be up and down the taper inlet scoop 7 of decentraction circle, wind is entered by the below, inlet scoop. Inlet air plenum 16 is set in volute and goes out air compartment 17, isolated by helical shunt body 8 between the two, this helical shunt body 8 is helical form plate bodys, and its radian is to consist of with three decentraction points circular arc different with three, and its radian total length is left-handed 210 ° of (see figure 3)s. The bottom of this helical shunt body 8 is connected with the inwall of taper inlet scoop 7. Be provided with staged spirality diffusing sheet 9 between Blower Housing 6 and helical shunt body 8, it is converted into the tapering silver of waveform (or stairstepping) by thin plate, curves to be connected from bottom to top on the helical shunt body 8 by left hand direction (counterclockwise) after fan-shaped. Adopt this spirality diffusing sheet 9, can be with the very fast air outlet that causes from bottom to top of the wind in the volute, ladder can prevent that wind from producing eddy current in flowing. Like this, not only guarantee the inhalation power to air intake, and made the direction of air intake and air-out consistent, thereby improved the emission effect to cooking fume. In addition, the utility model also is provided with a cooking fume remover 2(such as Fig. 1 in order further to improve the clean-up effect of cooking fume below the blower fan in exhaust fume collecting hood housing 1). It by much up and down staggered opposed "" shape filter 15 is arranged on and consists of (seeing Fig. 4 and Fig. 5) on the frame 14. Pollutant in soot gas repeated collision and sticking on the filter 15 in fleeing, the profit particulate that is not filtered sheet 15 adhesions is come out by the centrifugal force Re-isolation of blower fan again, concentrate to flow in the annular oil groove 18 around the exhaust fume collecting hood housing 1, the profit thing that filters out with filter 15 all flows among the lubricating cup 5.
The utility model compared with prior art has lot of advantages. Because blower fan is improved, be provided with simultaneously cooking fume remover, oil smoke discharge effect of the present utility model is improved greatly, can reach more than 95% an inhalation rate of oil smoke. The concentration of emission of oil smoke is lower than state specified standards (0.15mg/M3), to outside environmental nonpollution, power consumption descends greatly, can drop to 65W by original 80W.
Be embodiment of the present utility model below.
According to shown in Figure 2, Blower Housing 6 usefulness of the present utility model are thick makes the cylinder of φ 188mm for the sheet metal of 0.8mm, for gaining in strength, makes R apart from 25mm suitable for reading place
