Description

Dual filtering type cooking fume exhauster

Technical field

The utility model discloses a kind of dual filtering type cooking fume exhauster, belong to the cooking fume processing equipment technical field.

Background technology

At present, the employed kitchen fume treating apparatus of people all is ventilating fan or the range hood that does not have the filtration, purification function generally, adopt the shortcoming of said apparatus to be: in use for some time, the surfaces externally and internally of the body incrustation that is contaminated by smoke easily, clean very difficulty, internal body grease particularly, clean more difficult, and, grown the effect that also can have a strong impact on the pump drainage oil smoke service time, simultaneously, oil smoke is under undressed situation, directly be discharged into outdoor, can serious pollution of ecological environment.

The utility model content

For addressing the above problem, the utility model purpose be to provide a kind of reasonable in design, be easy to clean the effective dual filtering type cooking fume exhauster of filtration, purification oil smoke.

The technical scheme that its technical problem that will solve the utility model adopts is: a kind of dual filtering type cooking fume exhauster, comprise casing, be installed in the internal box in the casing, be installed in the spiral case in the internal box, the motor that wind wheel is installed in spiral case and is installed in control wind wheel on the internal box, bottom at casing is equipped with lubricating cup, in internal box, be positioned at spiral case below be installed with sealing plate, on sealing plate, be provided with at least one air inlet, be positioned at the motor that this air inlet place is provided with filter screen disk and is connected with filter screen disk, filtering screen is installed at the air inlet place that is positioned at internal box below sealing plate.

Of the present utility modelly further be set to: described filter screen disk comprises outer wheel disc and interior wheel disc, and outer wheel disc is connected by brace rod with interior wheel disc, is provided with the filter screen that is made of the filter screen silk between wheel disc and the interior wheel disc outside.

Of the present utility modelly further be set to: the air inlet on the described sealing plate is round, and identical or its diameter of the diameter of its diameter and outer wheel disc is slightly larger than the diameter of outer wheel disc.

Of the present utility modelly further be set to: the air inlet place on the described sealing plate is provided with the Oil Guide cup.

Of the present utility modelly further be set to: the bottom air inlet mouth place of described casing is hinged with safety glass.

After the utility model adopts said structure; exist the gas of oil smoke can be introduced into filtering screen; earlier the smoke particle that exists in the gas is tackled by filtering screen; gas is carried out the part filtration, purification; behind the process filtering screen; this gas enters the filter screen disk in the high speed rotary course again; again the smoke particle that exists in the gas or other material are tackled again by filter screen disk it is adsorbed on the filter screen silk; and it is got rid of peritropous Oil Guide cup by the filter screen silk; enter in the lubricating cup again by the Oil Guide cup; thereby realize the double filtration of oil smoke is purified, solved the problem that the gas of discharging no longer pollutes indoor-outdoor air.In addition, filter screen disk and filtering screen are that detachable is installed, and filter screen disk and filtering screen can be removed cleaning, and be very convenient.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model filter screen disk;

Fig. 3 is the structural representation of the utility model filtering screen.

The specific embodiment

As shown in Figure 1, the utility model comprises casing 1, be installed in the internal box 2 in the casing 1, be installed in the spiral case 3 in the internal box 2, the air outlet 14 of spiral case 3 is positioned at outside the casing 1, the motor 5 that wind wheel 4 is installed in spiral case 3 and is installed in control wind wheel 4 on the internal box 2, in the bottom of casing 1 lubricating cup 6 is installed, in internal box 2, be positioned at spiral case 3 below be installed with sealing plate 7, on sealing plate 7, be provided with at least one air inlet 8, preferred version is to be provided with two air inlets 8 on sealing plate 7, this air inlet 8 is round, be positioned at the motor 10 that air inlet 8 places are provided with filter screen disk 9 and are connected with filter screen disk 9, filtering screen 11 is installed at the air inlet place that is positioned at internal box 2 below sealing plate 7.Above-mentioned filter screen disk 9 comprises outer wheel disc 91 and interior wheel disc 92 as shown in Figure 2, and outer wheel disc 91 is connected by brace rod 93 with interior wheel disc 92, is provided with the filter screen 95 that is made of filter screen silk 94 outside between wheel disc 91 and the interior wheel disc 92.Above-mentioned filtering screen 11 as shown in Figure 3, be provided with into interior guard 111, the outer guard 112 of the deflector 110 of palisade arrangement in comprising, one end of interior guard 111, outer guard 112 all is provided with oil leaking hole 113, interior guard 111 places in the outer guard 112, interior guard 111 is combined into the parallel placement of dislocation with deflector 110 on the outer guard 112, oil leaking hole 113 on interior guard 111, the outer guard 112 overlaps, and interior guard 111, outer guard 112 are interference fit.The diameter of above-mentioned air inlet 8 on sealing plate 7 with outside identical or its diameter of the diameter of wheel disc 91 be slightly larger than outside the diameter of wheel disc 91, the gas that has oil smoke all can be entered in the filter screen disk 9 like this and carry out filtration, purification, prevent that part from existing the gas of oil smoke to be discharged from outdoor and contaminated air.Air inlet 8 places on the above-mentioned sealing plate 7 also are provided with Oil Guide cup 13.The bottom air inlet mouth place of above-mentioned casing 1 is hinged with safety glass 12, like this in the time of range hood work, the end that this safety glass 12 is positioned at lubricating cup 6 can break away from casing 1, and the gas that has oil smoke is entered in the casing 1, and safety glass 12 has the effect of guiding; When range hood was out-of-work, this safety glass 12 had played the effect of protection internal structure, prevents that some foreign matters from entering.
