Description

The environment-friendly type range hood

Technical field

The utility model relates to a kind of environmental protection utensil, and especially a kind of efficient environment-friendly type range hood of removing of mist of oil that culinary art the time can be produced belongs to household appliance technical field.

Background technology

The mist of oil that will produce in order will to cook the time is expelled to outdoor, generally can only use various types of range hoods at present, as the family kitchen range hood of the commercially available domestic and international brand of each grade in all kinds of markets.

Though it is outdoor that above-mentioned range hood can be expelled to mist of oil really, but can find that its efficient of taking off the oil extraction mist descends day by day after using a period of time, take off row's ability and have to unpick and wash until losing, to such an extent as to the streets and lanes in cities and towns occurs everywhere to unpick and wash the trade that range hood is job.

But, all users that carried out disassembly, cleaning know, not only dismounting is the annoying thing of part, and machine through unpicking and washing, it takes off row's ability and will significantly reduce, because must use grease and removing inhomogeneous of instrument spatula secure adhesion such as scoop on rotary parts such as impeller in the cleaning process, can destroy dynamic equilibrium, especially the loss that high-grade type is caused is bigger.

Produce above-mentioned phenomenon most important reason, be because the mist of oil that culinary art is produced directly enters in the machine, a part is expelled to outdoor, a part can constantly adhere on each interior parts of machine, especially produce the vitals impeller of negative pressure, the blade of measuring this impeller after deliberation adheres to mist of oil especially easily, finally causes motor speed to reduce and takes off row's ability drop.

For the critical defect of the range hood that solves above-mentioned present mass selling, generally use, the manufacturer of various countries once paid the effort of hardships with toing tell the truth for this reason, attempted to reduce the mist of oil or the adhesion amount of minimizing mist of oil in machine that directly enter in the machine.For example, the product of higher gears generally only is in the outside, inlet scoop of pressing close to range hood various forms of leakproof oil nets to be installed, and the part mist of oil is sticked on the leakproof oil net before in entering machine, flows in the oil drain pan of below along net then; And in order to offset the influence to negative pressure of resistance that leakproof oil net produces, the method that can only take to increase power of motor is compensated; And in order to reduce the adhesion of mist of oil each parts in machine that enter in the machine, what have sprays non-viscous paint at parts surface, and in order to remove the greasy dirt that adheres on the impeller, the range hood that has has increased cleaning device, in machine, spray cleaning fluid, to replace manual spray cleaning fluid.

More than enumerated the technology status of the range hood that generally uses at present, row's ability reduces such as taking off, the machine inner part adheres to hard nut to cracks such as mist of oil but various technical measures all can not effectively solve.Because: one, even expanded motor power increases leakproof oil net, finally also can cause unpicking and washing because of the long-pending oil of leakproof oil net, obstruction and impeller more and more heavily destroy dynamic equilibrium; Two, the method for spraying non-viscous paint on impeller and other parts, effect is extremely limited, because any non-viscous paint must not stop the adhesion of mist of oil; Three, manual or spray cleaning agent automatically method, not only bother, can not adhere to for a long time and must be the cooking after just can carry out, so in gastronomical process, be bonded at the mist of oil on leakproof oil net and the machine inner part, even each end of cooking cleaning (promptly enabling to do to obtain) also can not in time be removed and be caused mist of oil to be piled into dirt.

In sum, the present range hood that uses not only can not solve mist of oil and directly enter huge numbers of families directly to be disposed to airborne mist of oil every day probably be surprising.Especially in the city, even also be serious destruction to the environmental quality of short-term.Except environmental issue, in actual use, there is not a range hood really can accomplish to exempt to unpick and wash so far, do not say oil-feed problem in the machine, even if often unpick and wash or more change planes outer all kinds of leakproof oil nets, also be quite annoying thing.

The utility model content

The purpose of this utility model; be to make and a kind ofly can directly do not enter the mist of oil that the cooking produces in the range hood machine; and can make it in gastronomical process, constantly carry out surface activation and saponification; then with its collection or be expelled to outdoor range hood; to overcome the existing various critical defects of employed each model range hood at present, allow this range hood really accomplish to exempt to unpick and wash to reach in the protection indoor and outdoor surroundings.

Be the technical scheme below the novel employing of this this reality: this range hood is an inclined-plane vertical side exhausting type, middle position is provided with switch panel in the body upper end, thereunder be provided with body wide stir baffle plate, a removable lining liquid storage box is set below the body middle position; The outside at the suction opeing of pressing close to body, the vertical rectangular active oil removing screen component of one cover flat is installed, its upper end is topped lives whole suction opeing, its lower end extend into liquid storage box (holding the surfactant by family expenses liquid detergent and water configuration in this liquid storage box) bottom of body below, and the oil removing screen component is by framework, synchronous motor, active driving drum, driven driving drum, forms from electric brush rod, active oil removing net etc.; Suction opeing installed inside master's motor and impeller at body, in the gastronomical process that produces mist of oil, start the occasion of main motor and synchronous motor, because the negative pressure that impeller produces, mist of oil just passes active oil removing net and is inhaled into suction opeing, and meanwhile, active oil removing net is just constantly made cycle rotation up and down, constantly in liquid storage box, wash off and be bonded at online mist of oil, just constantly make cycle rotation up and down simultaneously, constantly in liquid storage box, wash off and be bonded at online mist of oil, stick surfactant simultaneously on the net.

Promptly can produce following unique deoiling effect this moment: when mist of oil when the active oil removing net of the bilayer that sticks surfactant passes through; because high speed airflow rubbing action; major part promptly combines with the online surfactant of oil removing; produce active reaction and saponification; make it to become the mist of oil that is stained with surfactant or become saponified; then together with the part mist of oil of slipping through the net again with machine inner part high-speed impact such as impeller; accelerated reaction; quicken saponification; final most mist of oil is all to carry the saponified of abundant moisture or to lose the saponified form in adhering Asia; drain into liquid storage box along the wind path wall in the body from liquid droping port; thereby further obtain neutralization; saponification; with reach be discharged into sewer reaction residue as dish water; both avoided the daily trouble of lubricating cup; environment can adequately protect again; drain into outdoor because no matter undressed oil smoke is the form with mist of oil; still drain into sewer with the form of fluid or abandon with the form of rubbish; all be very big destruction, and be on the rise overall situation or subenvironment.

Owing to adopted such scheme, the mist of oil that can reach in the gastronomical process to be produced directly do not enter in the machine, directly be not expelled to outdoor purpose, and through surface activation handle and the mist of oil of saponification also can not adhere to machine inner part and oil removing online; Simultaneously because active oil removing net is in the state of being cleaned all the time, no mist of oil and saponified accumulation, not only can not produce the phenomenon that resistance increases day by day, can reduce resistance relatively on the contrary, make mist of oil easily by mesh, improve the exhausting effect, because be stained with surfactant around the mesh all the time, frictional resistance during gas travels through significantly reduces, so need not to use expensive high-grade high-power suction impeller drive motors.

As mentioned above, oil removal machine of the present utility model is being in use except having aspect environmental protection the epoch-making important meaning, to the protection machine and to prolong machine service life also be very big contribution.In addition, daily maintenance also very is convenient and saves trouble, and can accomplish really to exempt from completely to unpick and wash, and only needs irregularly to add a little liquid detergent solution and gets final product.
