Description

Gashood type kitchen hood

Technical field belongs to field of household appliances the present invention relates to a kind of novel range hood.

Background material range hood is the household electrical appliance of herbal, the health of its relationship between quality to hundreds of millions people.However There is three defects very outstanding for traditional range hood.First is that oil smoke clean absorption rate is low, far from meeting people to family Occupy the requirement of air quality.The people of respiratory disease, incredible amount are caused because of kitchen fume pollution.Scientific research confirms kitchen Room oil smoke is the risk factors of the malignant tumours such as liver cancer, nasopharyngeal carcinoma.These have all caused the highest attention of people.Although in recent years Come numerous production men and be proposed miscellaneous Novel range hood, but the low situation of oil smoke clean absorption rate is not changed at all It is kind.Second is that greasy dirt is serious in loom, it is difficult to clean.The core component of fume-exhausting is centrifugal exhauster.When oil smoke enters in machine Though there is baffle, the measures such as filter screen produce little effect, and the hot oil cigarette of gasification drives straight in, through exhaust fan and turbine centrifugal power Effect is discharged from exhaust pipe, otherwise how long is stained with greasy dirt on impeller this is inevitable.Impeller can shake after being stained with greasy dirt Dynamic, noise etc. causes energy consumption to increase, reduced service life.And the cleaning needs of impeller unload entire loom and dismantle, and take a lot of work It is time-consuming, it is cumbersome.It is directly discharged into atmosphere third is that oil flue waste gas is unprocessed.Kitchen fume has been entire earth atmosphere One of most important pollution sources, many countries are using the external zero-emission of realization kitchen exhaust gas as environmental objective.

The low reason of kitchen fume waste gas purification rate be because exhaust gas four dissipate it is elegant, it is difficult to inhaled from a direction by it Firmly, very big suction is needed, and very big suction will generate very big noise, this is also unacceptable.So this is one A insoluble contradiction.

The invention proposes a kind of novel Gashood type kitchen hoods being very different with traditional range hood operating mode. Its main feature is that: 1, purification of waste gas rate be substantially improved, and fully achieves satisfactory degree.2, greasy dirt is substantially in machine Mitigate.3, machine volume substantially reduces, and reduces production cost, has saved kitchen space.4, oil flue waste gas is greatly reduced Outdoor discharge amount, energy conservation and environmental protection.

Range hood of the present invention is mainly made of three systems: high-speed flow generating system, exhaust gas suction strainer comb Road system and electric control system.The invention mainly relates to the first two systems.In addition range hood of the present invention, its function Can and control system be single machine it is corresponding list stove, but when being made into product can also by correspondence eyes stove two looms be incorporated into In same shell.

The working principle of the range hood is the high-speed flow generating device by outfit, along pot periphery suitably away from Cylindric very thin high-speed flow curtain is enclosed from generation one, from top to bottom, is directed reach hearth with baffle as lid, is formed one together Oil flue waste gas is all covered, does not make to spread by " cover ", then passes through the suction strainer draining pipeline system positioned at loom centre It sucks and filters discharge.It is in brief " first covering suction again ".Realize that kitchen fume exhaust gas is whole controllable.

A good range hood key is made into be that oil flue waste gas can be controlled.Gashood type kitchen hood is accomplished: Since high-speed flow itself is air, cleaning and it is transparent, have transitive signature, cooking operation will not be counteracted.

Detailed description of the invention: Figure of description 1 is the structure and working state schematic representation of range hood of the present invention.

Specific embodiment: it is described in detail below by one embodiment combination attached drawing of range hood of the present invention: As shown in the figure: the suction strainer draining pipeline system of Gashood type kitchen hood is similar to upside down funnel in the middle position of loom." funnel " Cup-like portion be baffle [1] corresponding with pot, more bigger than pot, the edge one of baffle encloses inward curl into ditch [2] shape, can Generated sewage after undertaking steam, oil and gas condensation, leads to sewage collector.The tubular portion of " funnel " is at the center of baffle Position.Bottom is circular air inlet [3] and blast pipe [4], is provided with condensation and filtration facility in blast pipe.Blast pipe Top is exhaust fan [5], then is up exhaust pipe [6], together constitutes totally enclosed suction strainer draining pipeline system.Plastics are made Condensation cup [7] be placed on the bottom of blast pipe, the latticed good permeability of bottom of a cup, the built-in thin plastics for spiraling into cylindrical body It manages [8], is packaged with water in pipe, freezing in refrigerator is placed on before use.Effect is that waste water vapour, the condensation discharge of waste oil vapour are subtracted as far as possible Few its enters upper filter cup [9], and filter cup fills loose porous, the strong mistake of absorption oil smoke ability shaped like cup is condensed in cup Filtering agent [10].Replacement in due course for convenience is provided with " door " [11] that a fan is opened from the outside on blast pipe.For convenience Cleaning, is also provided with " door " [12] that a fan is opened from the outside at exhaust fan.

Close to the edge of baffle be annular hollow gas boosting storehouse [13], pressurization storehouse bottom have a circle against stove The narrow gap of platform, i.e. annular lip puff prot [14].There are an air inlet [15] miniature by pipe [16] and one on pressurization storehouse Air pump [17] is connected.Air pump, pressurization storehouse and puff prot constitute high-speed flow generating device.

When work, gas caused by air pump is constantly defeated to pressurization storehouse, and generated high pressure gas is from puff prot after pressurization It constantly sprays, forms high-speed flow curtain [19] along the periphery of pot [18].Here so-called high speed is and in contrast, generally cooks a meal The all thin light hot gas of thing oil flue waste gas does not form air blast, will not head-on contact with air curtain in orientation, so even if The little air curtain of speed can also bottle up oil flue waste gas, not make to leak.

Traditional range hood can only use high-power, big suction, large area suction since oil flue waste gas be unable to completely control Mode.Air inlet is unlimited, and area is very big, so loom is also made very big, however the major part of suction is untainted Air, therefore effect is low, noise is big.In contrast, " first covering, then suction " has following advantage: 1, oil flue waste gas covers completely Firmly, waste gas purification rate is substantially improved in room, and air quality can reach satisfactory degree.2, it is inhaled due to being greatly reduced The working range and workload of kitchen ventilator, simplify structure, reduce energy consumption.The daily frying pan of ratio that loom is done is slightly larger, small It is skilful exquisite, production cost is not only saved, while also ing save the kitchen space of user's preciousness.3, it is complete after oil flue waste gas covers Portion sucks suction strainer draining pipeline system and concentrates discharge, is advantageous to the purified treatment of exhaust gas, realizes zero outside kitchen pernicious gas room Discharge this global target be follow a well mapped-out plan, the thing that when the water comes, a channel is formed.4, exhaust gas discharges after processing, greasy dirt feelings in machine Condition can greatly improve.
