Description

The full-automatic smoke exhaust ventilator of a kind of magnetic suspension drum-type rotator type

Technical field:

The utility model relates to a kind of smoke exhaust ventilator, be particularly related to a kind of magnetic suspension drum-type formula rotor, energy-saving effect is given prominence to, is exempted to unpick and wash, frictional resistance is little, noiselessness, can produce self-suction, top band bin, multi-size, computer Automatic Control, both can be used for family, and can be applicable to the smoke exhaust ventilator of the environment that fume pollutions such as restaurant, various dining room are big again.

Background technology:

At present along with expanding economy, the raising of living standards of the people, people are also more and more higher to the quality requirement of life, and smoke exhaust ventilator has become the indispensable article of family.Smoke exhaust ventilator on the market is numerous in variety, function is advanced day by day, as self-regulated nodal pattern, deep suction type, power saving silence type of having microcomputerized control etc. have come into the market, it forms brand the product of many producers, handsome health, Wan Jiale, side wait very much a collection of best brand of product to be subjected to the favor of domestic and international market day by day, external best brand of product such as elite etc., also enter China market in a large number, smoke exhaust ventilator is just bigger towards draft, more power saving, noise is littler, control ability is more, automaticity is higher direction develop.

But the said goods also exists blemish in an otherwise perfect thing needs improved aspect.

One, energy-conservation and increase draft aspect

Also not making full use of fluid mechanics principle, no matter be updraft type or side-suction type, all is that the flabellum of keeping watch directly is contained on the axis of motor, and motor is in occupation of the centre position, the thrust air-flow that the fan leaf produces be dispersed in motor around.Thousand aerofoil profile fan leaves mostly are vertical arrangements, the thrust that produces is the power that the annular side direction promotes, the air-flow that nature is risen disperses, all push away the gas 1/3-1/4 in one week and only account for by gas port, remaining part not only can not form effective push but also can produce part resistance air-flow vortex, so just can not bring into play and utilize the airway dysfunction that pushes away of fan leaf effectively, stream has taken certain energy, though also can produce stronger draft, but this is the effect of that part of generation of 1/3-1/4 in whole fan leaves, the utilization rate of electric energy only accounts for 1/3-1/4, caused severe energy waste, and in order to increase the power of bleeding, many producers have descended many time on motor, though can improve the power of bleeding, but this will be a cost to improve power consumption still, the thrust of the fan leaf generation of vertically arranging is to side direction, air-flow to be introduced in the cabinet deposit air chamber after just can enter flue, air-flow will will make the air pressure increase and form certain resistance through complications, and overcoming this part resistance generation vibrations also will increase power consumption.

Two, fume pollution aspect

Soot particles very easily adheres to the surface of the inside and outside various assemblies of smoke exhaust ventilator, and the pollution that causes year in and year out reduces the function of smoke exhaust ventilator on the one hand, and cleans very inconvenient.Therefore, many producers have generally used not oil sticking surface lacquer reduce polluting as an important problem, but type and oil smoke path be designed to the problem that fume pollution is difficult to overcome.Motor and casing thereof are arranged in the middle of the cigarette road, and this must become the target that greasy dirt dyes, and the oil that it produces above also needs special oil circuit, and the oil circuit of the motor portion of as above suction type smoke exhaust ventilator also must have the swab case of a special use.This swab case generally all is arranged on the plume central top.This had both occupied favourable space, and itself becomes the target of fume pollution again.Thousand wing fan leaf vertical array, can not utilize the liter of rising of oil smoke self, directly enter flue, oil smoke all will be through the promotion of passing through fan leaf, the chance that the fan leaf is contacted with oil smoke increases, the complications of flue have increased this chance again, deposit smoke-box and mostly are arranged in the casing, and this part is the easiest pollution of oil smoke and cleans difficulty.

Three, reduce the noise aspect

Smoke exhaust ventilator produces the reason that noise mainly contains following aspect:

(1) rotation of motor itself and vibrations.

(2) rotation of fan leaf and vibrations.

(3) vibrations of circling round of air-flow.

(4) vibrations of casing.

Present many producers are doing a large amount of research aspect the noise reducing, and as happy the having only wind, do not have sound of ten thousand families, the product noise of some famous brand producers is very little, but in order better to reduce noise, aspect structural design, also has following problem.The support of motor, motor one end is fixed, an end dissociative, the fan leaf is connected the free-end of motor, fan leaf one end dissociative is the obstacle that causes motor and fan leaf generation vibrations and noise to be difficult to overcome, and the complications of flue are to cause the reason of air-flow vibrations and vibrations casing.

Plume aspect when four, unpowered

The air of air pressure eminence flows to the air pressure lower, it also is this reason that flue gas rises, the same with general oven flue, when cooking stove begins to kindle a fire and cook a meal or heats up water, fire, cigarette and steam, oil smoke etc. form a hyperbar, if the flue in the general cooking stove, the suction that it just produces a nature enters the space with the cigarette road, the cooking stove of current use gas range or other form, when kindling a fire and cook a meal or heat up water, be not all will open smoke extractor, can take very much like that, only big at oil smoke, steam is just opened smoke exhaust ventilator for a long time.Do not open smoke exhaust ventilator at ordinary times, this situation year in and year out, also polluted in the kitchen, though reason is existing a spot of pollution when kindling a fire and cook a meal or heating up water, the pressure of air obviously increases on the stove, tangible rising steam or oil smoke are arranged, the valve switch of smoke exhaust ventilator flue portion but its pressure is not opened.Present valve switch is to be made by plastic sheet, its weight is about 25-45 gram, and every square centimeter of air pressure restrains at 1-1.5 and could beat when above, and the air flow in the time of can only starting by smoke exhaust ventilator just can be opened, and when not driving smoke exhaust ventilator, only do not open by the thermal current pressure of rising naturally liter.Therefore when not starting shooting, air-flow can not lean on rising of self to rise eliminating, and this has just caused certain pollution.Generally be difficult to accomplish to take very much like that once the start of lighting a fire.

Five, scope of application aspect

Present smoke exhaust ventilator generally all is applicable to family, and the restaurant, dining room, the high-power smoke exhaust ventilator that the environment of long-time a large amount of fume pollutions is not fit to makes that the fume pollution between restaurant, many dining rooms, cooking stove is serious, is the major reason that influences restaurant, dining room poor hygienic.

Six, applications design aspect

1, on outward appearance, the smoke exhaust ventilator of various forms all be difficult to the kitchen in design coordinate.、

Though 2, the housing of smoke exhaust ventilator has adopted stainless steel, and oily dirt free material, but its upper face is messy all the time, year in and year out, whatsoever the upper surface of material all can become and is contaminated by smoke and a weak link of bad scouring, cover smoke exhaust ventilator top in some family even through Polypropylence Sheet commonly used, in case pollute on top.

3, each space in the general kitchen all requires effective utilization, no matter be the size of kitchen area, all require on layout neatly, and the smoke exhaust ventilator upper space is difficult to effectively utilize.

Seven, automation control aspect

Along with science and technology development, the smoke exhaust ventilator of many brands all is provided with automatic control system, but aspect automation imperfection also, also need to improve.

1, many types all are provided with Auto Power On, be that carbon monoxide perception and sensing device are housed in the machine, but there is not the complete machine automatic closing system, the sound of modern smoke exhaust ventilator is more and more littler, during open state, basically can't hear sound, this has also caused the generation of often having forgotten shut down event, make it be in duty for a long time, some people even to just find that lampblack absorber is also changeing when cooking next time, investigating according to us that smoke pumping machine burning machine (being that motor burns out) has more than 80% is owing to forgotten shutdown, due to just the motor continuous operation reached tens of hours.

2, smoke exhaust ventilator is not established the gas leakage warning device, and this mainly is that the resolution capability of gas leakage is difficult to control, because gas-fired is bad when generally cooking certain coal gas flavor is always arranged.But the prestige that gas leakage causes evil is again the calamity in the kitchen.This phenomenon is all very high at the occurrence rate in various places every year, and we think that smoke exhaust ventilator should have its special function aspect the coal gas reporting to the police and take out unexpected the leakage.

3, present smoke exhaust ventilator can not be regulated drafts automatically along with what of oil smoke in the kitchen, but by manual adjustment, so not only inconvenience but also untimely caused the certain pollution and the waste of electric power.

Eight, modern kitchen much all is can be independently, and the people cooks therein and cooks, and the atmosphere of impersonalityization is used as cook as a kind of tasteless coolie, should make it be full of fast happy entertaining.Therefore, should be in smoke exhaust ventilator, setting can be listened light music, listens the basic hygienic knowledge of some diet, cooking knowledge, menu dish ballad etc.
