Description
Technical field
The present invention relates to a kind of air cleaning unit, especially relate to a kind of family kitchen air purifier.
Background technology
In gastronomical process, edible oil can form the mixture of a kind of gaseous state, liquid state and solid-state 3 kinds of organic forms under the high temperature conditions, i.e. oil smoke.According to the difference of form, the mixture of liquid particles and solid granulates is called as mist of oil, and these particles are divided into can sedimented particle and inhalable particles; Gaseous parts is VOC (VOCs), and the gaseous contaminant in family kitchen also has burnt gas.Can the particle diameter of sedimented particle mainly be distributed between 10-400um in oil smoke, these particles are subject to the effect of self gravitation and the interaction between particle and particle can be deposited to ground and other implements surface, can not produce persistence pollute air in kitchen environment.Usually particle diameter is called inhalable particles at the particle of below 10um, i.e. PM10, these particles are not easy sedimentation, always swim in air in kitchen environment, it can be sucked by human body, is deposited on the position such as respiratory tract, alveolar thus diseases induced, is detrimental to health.The particle diameter of particle is less, and the position entering respiratory tract is darker.The particle that in inhalable particles, diameter is less than or equal to 2.5um is called as can enter lung particle, i.e. PM2.5, and particle diameter is greater than 2.5um, is less than the Particle Phase of 10um ratio, the harm of PM2.5 to human body is larger, and VOCs is by aerial chemical reaction, also PM2.5 can be formed.
Present cooking fume pollutes and has become very valued indoor environment problem to the Health cost effect of human body.Smoke exhaust ventilator is as a kind of electrical equipment purifying kitchen environment, the oil smoke produced in the waste gas of cooking stove burning and cooking process can be taken away rapidly, be discharged to outdoor, decrease the pollution to air ambient in kitchen, but wish just waste gas, oil smoke and peculiar smell thoroughly to be drained by means of only smoke exhaust ventilator clean also very difficult, because always have the part of escape in aspiration procedure, and these waste gas, oil smoke and peculiar smell of failing to be discharged just rest in kitchen, threaten the health of people, and use smoke exhaust ventilator can not improve original air quality in family kitchen.The demand that simultaneously present consumer opens wide for family kitchen is than stronger, and in gastronomical process, kitchen is once open wide, although use smoke exhaust ventilator, the air ambient in dining room and parlor still can be affected.
In recent years, along with the public is for the raising of air quality and own health attention degree, air purifier produce market is expanded rapidly.But up to the present, not yet there is the air purifier product being specially adapted for family kitchen, this air ambient mainly due to family kitchen is comparatively special, compare with general indoor air environment, in air in kitchen environment there is catabolite (VOCs), the burnt gas (carbon monoxide and nitrogen oxide etc.) of chemical change in many oil droplet particulate, edible oil and food in heating process, and it is moister, under such indoor air environment, general air purifier can not be finished the work.
Use if general air purifier is placed in family kitchen air ambient, for the air purifier using gac filtration net, activated charcoal strainer first can touch incoming air, owing to there is oil droplet particulate (belonging to liquid particles) in air, and air is moister, in use, activated carbon granule can absorb a lot of moisture, be easy to produce peculiar smell, simultaneously its oil droplet directly touched can be attached on particle surface adsorption hole is blocked, to such an extent as to after using very short a period of time, it adsorbs pernicious gas, the effect eliminated the unusual smell will be had a greatly reduced quality even entirely ineffective.For the air purifier using NACF screen pack, HEPA high efficiency particulate air first can touch incoming air, the moisture in a large amount of oil droplet particulate of stopping in air of its meeting, solid granulates, absorption air.Due to filament self the not oleophylic not hydrophilic (the oil droplet particulate that it is stopped, the moisture of absorption all rest on fiber surface) of HEPA high efficiency particulate air material used, oil droplet particulate in air can wrap on filament, add the solid granulates that it retains, in this case, filament and filament can very soon cementing be attached on together with, after using very short a period of time, the windage of HEPA high efficiency particulate air will become very large, has a strong impact on normal use; Screen pack is inner becomes moist because sucking large quantity of moisture, grows can to like this bacterium in a large number and provide convenient environment.In addition, the light for general air purifier decomposes link, and its Catalytic Layer is very afraid of oil, is disposed by oil if do not decompose each link above by light, and its Catalytic Layer will be covered by greasy dirt and cause light decomposition ineffective.Therefore, for general air purifier, if wish to use in air in kitchen environment, these problems are all unavoidable above, the service life of air purifier can shorten greatly due to the particularity of environment for use, its normal use can be had a strong impact on and be limited, and after the short time uses, it self will become pollution sources.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figures 1 to 6, family kitchen air purifier in the present embodiment comprises shell 1, shell 1 is respectively equipped with front end air inlet 11 and rear end air outlet 12, shell also has side plate 13 and base plate 14, between front end air inlet 11 and rear end air outlet 12, be provided with filtration channel in shell 1 inside, in filtration channel from front end air inlet 11 to the back-end air outlet 12 primary efficient filter screen 2, mechanical filter 3, rotary sieve 4, blower fan 5, deep layer deoiling net 6, oleophobic hydrophobic filter net 7, activated charcoal strainer 8 and photocatalyst device 9 are installed successively.
Wherein, primary efficient filter screen 2 and mechanical filter 3 are configured for filtering the prime filter compared with coarse grain footpath particulate, and deep layer deoiling net 6, oleophobic hydrophobic filter net 7 and activated charcoal strainer 8 are configured for filtering the rear class filter compared with fine grain particulate.
Concrete ground, blower fan 5 is centrifugal blower, primary efficient filter screen 2, mechanical filter 3 and blower fan 5 are located at the latter half of shell 1 inside from front to back successively also near front end air inlet 11, case 18 is provided with in the first half of shell 1 inside, passage is formed in case 18, deep layer deoiling net 6, oleophobic hydrophobic filter net 7, activated charcoal strainer 8 and photocatalyst device 9 are located in case 18 from front to back successively, the through hole be connected with blower fan 5 air outlet is had in the bottom of case 18, blower fan 5 air outlet is upward and towards deep layer deoiling net 6, in the bottom of shell 1, oil collection box 10 is installed, and oil collection box 10 is positioned at the below of mechanical filter 3 and rotary sieve 4.In addition, the rear end of shell 1 is provided with gauge tap 16 and circumscripted power line 17.
Overall thought in the development of this family kitchen air purifier is: first thick rear essence, often step are spun out, different method is superimposed, by different purification method Combination application at one piece, and the object that cooperative achievement purifies.First the bulky grain in air is got rid of when removing particulate pollutant, again by middle or small in air, more granule get rid of, extend the service life of each purifying part in clarifier, and meet purification utensil performance requirement after making each purifying part comprehensive simultaneously.During clarifier work, the air to be clean entering filtration channel from front end air inlet 11 flows out from rear end air outlet 12 successively after above-mentioned filter assemblies layered filtration, purification and photocatalyst device 9 light decompose.
Primary efficient filter screen 2 in the present embodiment adopts high-quality polyethylene terephthalate to make; capable of washing; its thinner thickness; filter mesh is also larger; be mainly used in the hair in filtering air, fiber suede, bulky grain thing, scurf etc., the effect of protection family kitchen air purifier rear end all parts can be played.
Mechanical filter 3 in the present embodiment, rotary sieve 4 and deep layer deoiling net 6 mainly design for the oil droplet particulate in air, and certainly, they also can stop solid granulates.Wherein,
Mechanical filter 3 is located between primary efficient filter screen 2 and blower fan 5 air inlet, and mechanical filter 3 includes the cylindrical filter sheet 31 that two rows are oppositely arranged, the U-shaped groove structure of each cylindrical filter sheet 31, and the U-type groove notch of two organ timbering shape filters 31 relatively and be mutually engaged.Mechanical filter 3 utilizes inertial collision principle to make, when air runs into the stop of object in motion process, air-flow will change direction and stream, oil droplet particulate tiny in air and solid granulates can be followed together with air-flow and be flowed, and thick oil droplet particulate and solid granulates can depart from streamline owing to having larger inertia, keep the inertia motion of self, oil droplet particulate thick like this and solid granulates just and object collide and separate from air, its particle stopped, some meetings fall in the oil collection box 10 below filtration channel under gravity, what have then can be attached on the inwall of mechanical filter 3.We adopt the method in adjustment filtration channel shape, gap, reach the object that the windage flowed while can stopping a certain size particle is suitable, passage can not be blocked.
Rotary sieve 4 is located at the air inlet of blower fan 5 and is arranged on the motor shaft 51 of blower fan 5, and rotary sieve 4 is just to mechanical filter 3.Rotary sieve 4 is shielded by dynamic mechanically effectively to tackle oil droplet particulate in air and solid granulates, adopt physics centrifugal principle simultaneously, (used on family's kitchen air purifying device by specially designed net dish, neither affect overall flow, also overall noise is not increased) High Rotation Speed, produce centrifugal action, the oil droplet particulate be blocked and solid granulates are effectively thrown in oil guide groove, then flow in oil collection box 10, thus reach the object of purification incoming air.When air is by rotary sieve 4, whether great or small, every capital that can touch net dish is kept off the particle in air.
As shown in Figure 7, deep layer deoiling net 6 is divided into front end layer 61, intermediate layer 62 and back end layers 63, front end layer 61, intermediate layer 62 and back end layers 63 are fiber braiding layer, the count of front end layer 61 is greater than the count in intermediate layer 62, and the count in intermediate layer 62 is greater than the count of back end layers 63.The filtering material that deep layer deoiling net 6 uses forms through particular form and craft woven, filter material has certain thickness, belongs to profound filtration, and filter material internal fiber braiding density degree is different, its fibr tissue loosens simultaneously, and the high voidage formed adds the appearance amount of cutting of impurity.Larger particles in incoming air can be trapped in fiber surface by filter material, to catch in the internal fiber of filter material deep layer front end compared with granule, fine particle is caught in the internal fiber in the middle of filter material deep layer, by more fine particle seizure is in the internal fiber of filter material deep layer rear end, it has high filter efficiency and high service life when keeping low windage.Be different from common screen pack and directly will be greater than the particle interception of filter mesh on screen pack surface, the feature of deep layer filter material catches particle by intensive filament.Weave this filtering material use filament to be utilize string and can jointly make the fibrous material of adsorbed oil, the moisture of the oil droplet particulate that such filter material is stopped and absorption would not rest on filament surface but enter into filament inside, such filament and filament would not oil droplet particulate under the acting in conjunction of solid granulates cementing be attached on together with, the normal use of deep layer deoiling net can not be had influence on, thus keep the normal work of clarifier, will be shortened in the service life of clarifier due to the particularity of air in kitchen environment.The filter material of deep layer deoiling net is accordion, and filter area is large, dust containing capacity is high, life cycle is long, meets the thought often walking and spin out, and simultaneously fold-like structures also enhances the intensity of whole deoiling net, make it when making moist, pressurized not yielding.This deep layer deoiling net can reach the sub-high efficiency particulate air standard of EPA of E12 filtration grade (EN1822-2009) for the filter effect of particle.
Oleophobic hydrophobic filter net 7 in the present embodiment is the HEPA high efficiency particulate air of glass fibre material.HEPA high efficiency particulate air is a kind of internationally recognized best filter material, and it is interwoven by very tiny organic fiber, stronger to the capturing ability of particulate, aperture is small, and adsorption capacity is large, and purification efficiency is high, feature is that air can pass through, but tiny particulate cannot pass through.The use material of HEPA has PP fiber, glass fibre, PP/PET composite, melt-blown terylene non-woven fabric and melt-blown long fibre on the market at present, wherein adopts the filter effect of glass fibre material better.What the present embodiment adopted is the HEPA high efficiency particulate air of the glass fibre material of H13 filtration grade (EN1822-2009).
