The range hood, also known as the range hood, is a kitchen appliance that purifies the kitchen environment.It is installed above the kitchen stove, which can quickly remove the waste fumes that are harmful to the human body during the burning waste and cooking process. At the same time, the oil fume is collected to reduce pollution, purify the air, and have the safety of anti -toxic and explosion.Sales.
Main classification of range hood
The range hood can be divided into three types according to the appearance: one is Chinese hood, the other is a European hood, the third is the side suction type, and the fourth is the multimedia smart machine.[1] can also be divided into upper, side -row, and lower row types.[2-3]
Chinese hood
It is mainly divided into old -style shallow -absorbing hood, especially the main elimination objects.It is an ordinary exhaust fan that directly discharge the oil fume outdoors.The biggest problem of deep -absorbing hoods is to occupy space, have a lot of noise, easy to meet, the oil smoke is not clean, the service life is short, the cleaning is not convenient, and the environmental pollution is large.
European hood
The multi-layer oil net is filter {5-7 layer} to increase the power of the motor to achieve the best effect. Generally, the power is above 200 watts.The characteristics are: beautiful appearance and expensive price, suitable for high -end user groups.Most of them are flat net filtering nets, hanging type installation structures.
Sideline
The advantage is that it is not easy to meet. The appearance is fashionable. The smoke port is close to the oil fume. The effect is good. If you like it, you can accumulate oil at the bottom. The raised part is easy to affect the operation.
L -shaped range hood
The L -shaped range hood was improved to the side suction problem, and the original side of the original side was highlighted to the two upper and lower air outlets.The main smoke port concentrates the suction power in the area where the lower part of the oil fume occurs. Before the oil fume diffuses, almost all forces will be sucked away.Pulling away.
Smart hood
The perfect combination of modern industrial automatic control technology, Internet technology and multimedia technology provides models for modern smart kitchen, leading modern kitchen into the dynamic era of entertainment and enjoyment.But there is a certain technical bottleneck from the actual popularity.
According to the model of the fan, the range hood can be divided into two types: shaft flow and centrifugal type.The axis flow fan is generally equipped with a shallow cover, with large air volume and small wind pressure; centrifugal fans have large wind pressure.The range hoods sold in the market are mainly centrifugal types, so there is not much room for choosing on the model. Generally, it is an external type and a centrifugal fan.
According to the structure, the range hood is mainly deep and thin, and there are half -deep, European -style and pumping models.There are three types: thin, deep, and cabinet -type hoods on the market.
Deep range hoods have a high smoke exhaust rate, which can match with different styles of modern kitchen furniture. Deep outer masks can smoke cooking oil fumes in a larger scale.The smoking rate is greatly improved.
The thin range hood is light, small, and easy to suspend, but its thin design and lower motor power make a considerable part of the cooking oil fume cannot be included in the range of smoking. It has the opportunity to escape indoors.Other two types.
The cabinet range hood is composed of a smoke exhaust cabinet and a special oil hood. The oil fume cabinet is cone -shaped. After the fan is started, the cabinet forms a negative pressure area, and the external air is supplemented to the inside.The oil fume and other exhaust gas cannot escape, ensuring the cleaning rate of oil fume and nitrogen oxides.
According to the number of motors, the range hood is divided into two types: single motor and dual motor.
According to the control method, the range hood can be divided into two types: mechanical switch control type and electronic switch control type.
Analysis of misunderstanding of oil smoke buying
According to studies, among non -smoke -absorbing women who induce lung cancer, more than 60%of women have been in contact with kitchen oil fume for a long time. In the kitchen environment with poor smoke exhaust effect, the harm to health is equivalent to sucking two packs of cigarettes a day. In this case, this is the case.As a result, 1.6 million people worldwide die.Experts point out that in addition to correctly controlling oil temperature and cooking time, the range hood should be selected correctly.
Due to the close -range smoking and open design of the side -suction range hood, the side suction machine has gradually occupied the market, becoming a major mainstream in the range hood market.However, in the face of a large -scale side switch, consumers should polish their eyes and avoid the following six misunderstandings.
Misunderstanding 1: "Circle inlet can enter the wind at 360 °" misunderstanding.There is a circular mouth in the middle of many side suction machines on the market, claiming to be 360 ??° in air.However, in fact, the oil fume generated by the stoves of the stoves is distributed on both sides, and the cigarettes in the center can only ensure that the cigarettes closest to the center areas are in full direction.The air inlet is only an open design of 360 °, and it is not the entire entry of cigarettes.Then to suck the cigarettes of the two stove heads at the same time, it is necessary to ensure a generous air inlet.
Misunderstanding 2: "The greater the air volume, the better the smoking effect".The good or bad smoking effect cannot be judged by the air volume alone. The heavy air volume not only cannot inhale the oil fume, but also disrupt the flow of the oil foam and gas.The "Eleventh Five -Year Project" research shows that the most suitable air volume of public flue is 15m3/min, not as big as the better.In theory, the air volume and noise of the fan are a natural contradiction. The more the air volume is over, but it will cause unbearable noise.
Misunderstanding 3: "You have more clean" misunderstandings. "The side suction cigarette is cured, and the oil fumes that are naturally exposed to the natural oil are also earlier. Gas oil exposed to the oil net and started to encounter cold condensation into liquid. When the oil droplets condensed to a certain degree, the smoke could no longer pass through.Therefore, in order to change the troubles of this kind of oil net, technical experts have developed the oil -free network design of the "three -heel fume separation technology". Filtering oil fume through multi -layer technology, becoming a modern side suction machine is a technological innovation.Clean oil network problem.[1-3]
Misunderstanding 4: "The removal of the disassembly and washing machine can really be exempt from disassembly."The real oil fume separation is separated from the centrifugal force generated by the high -speed rotation of the impeller. On the market, it is claimed to be free of disassembly and washing side suction.The function of a filter is enlarged into a net that can be filtered out of thousands of oil fume. It is obviously impossible. Only with better fan oil -proof coating and good daily maintenance can ensure long -term efficient operation of the hood.
Misunderstanding 5: Panel material is irrelevant
Regarding panel materials, the promoters may "deliberately forget" not to mention it, or directly say the term of a certain alloy to flicker consumers.In fact, it is also very simple to test the material. The best domestic materials are generally made of imported M-CR stainless steel, which looks fine and textured.This material is anti -oxidation, corrosion resistance and brighter and brighter.To distinguish the difference between such materials and general alloy materials, you only need to try it directly with magnets. If you can suck it, it must be general inferior alloy or iron.Another kind of panel is protected by Teflon coating. It has the advantages of non -sticky oil to clean and anti -corrosion. It is another excellent panel material in addition to stainless steel.
Misunderstanding 6: Inner cavity design is not important
The importance of the inner cavity design of the range hood cannot be ignored. On the one hand, it is necessary to be as seamless and easy to clean as possible. At the same time, it must be able to protect the lines and enable various lines to work properly under the condition of strong corrosion of oil fume.Corrossed.The seamless design in the inner cavity is not only seamless in the cavity, but also the small surface that is parallel to the stove can be seamless. At the same time, the combination of the oil net and the inner cavity must be "invisible and seamless."For example, setting oil -proof walls, etc., this is really without cleaning dead ends.
