Description

Dual filtering type cooking fume exhauster

Technical field

The invention 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.

Summary of the invention

For addressing the above problem, the object of the invention 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 present invention will solve the technical scheme that its technical problem adopts: 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 first air inlet, be positioned at the motor that this first air inlet place is provided with filter screen disk and is connected with filter screen disk, be provided with second air inlet on the internal box being positioned at below the sealing plate, filtering screen is installed at the second air inlet place.

The further setting of the present invention is: 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 inventionly further be set to: first air inlet on the described sealing plate is round, and identical or its slightly larger in diameter of the diameter of its diameter and outer wheel disc is in the diameter of outer wheel disc.

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

Of the present inventionly further be set to: the bottom of described casing also is provided with the 3rd air inlet, is hinged with safety glass at the 3rd air inlet place.

After the present invention 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 present invention is described in further detail.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the structural representation of filter screen disk of the present invention;

Fig. 3 is the structural representation of filtering screen of the present invention.

The specific embodiment

As shown in Figure 1, the present invention includes 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 first air inlet 8, preferred version is to be provided with two first air inlets 8 on sealing plate 7, this first air inlet 8 is round, be positioned at the motor 10 that first air inlet, 8 places are provided with filter screen disk 9 and are connected with filter screen disk 9, be provided with second air inlet on the internal box 2 being positioned at below the sealing plate 7, filtering screen 11 is being installed at the second air inlet place.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 first air inlet 8 on sealing plate 7 with outside identical or its slightly larger in diameter of the diameter of wheel disc 91 in the diameter of outer 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.First air inlet, 8 places on the above-mentioned sealing plate 7 also are provided with Oil Guide cup 13.The bottom of above-mentioned casing 1 also is provided with the 3rd air inlet, be hinged with safety glass 12 at the 3rd air inlet place, 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, 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.

Operation principle of the present invention: press switch 15; motor 5 drives wind wheel 4 work; motor 10 drives filter screen disk 9 rotation at a high speed; wind wheel 4 produces suction; force the gas that has oil smoke to enter in the casing 1 by spiral case 3; and then enter filtering screen 11 again; earlier the smoke particle that exists in the gas is tackled by filtering screen 11; and the smoke particle under will tackling enters lubricating cup 6 by oil leaking hole 113; thereby gas is carried out filtration, purification; this gas is behind process filtering screen 11; enter filter screen disk 9 in the high speed rotary course again by first air inlet 8 on the sealing plate 7 again; again the smoke particle that exists in the gas or other material are tackled again by filter screen disk 9 it is adsorbed on the filter screen silk 94; and it is got rid of peritropous Oil Guide cup 13 by filter screen silk 94; enter again in the lubricating cup 6 by Oil Guide cup 13; thereby realize the double filtration of oil smoke is purified; this gas enter at last be discharged from behind the spiral case 3 outdoor; solve the problem that the gas of discharging no longer pollutes indoor-outdoor air, reached the purpose that purifies air.
