The kitchen is the heaviest place in the house, and long-term inhalation of kitchen fumes can cause respiratory diseases such as rhinitis and pharyngitis, and even increase the risk of lung cancer. Therefore, a good range hood is very important. So how to buy a household range hood? What are the classifications of household hoods? The following decoration home decoration network Xiaobian will bring you the main points of the household range hood, for your reference when purchasing.
How the household hood works:
After the power is turned on, the motor drives the wind wheel to rotate at a high speed, so that the air pressure difference is generated inside and outside the intake hole of the range hood and inside and outside the exhaust port, so that the soot can be blown to the outside with the rotation of the air in the inner cavity of the volute. At the same time, in the process of eliminating the soot, some high-temperature oil particles in the soot are attached to the inner wall of the volute under the action of the centrifugal force of the wind wheel, and after being condensed into oil droplets, they flow back to the oil collecting device under the action of gravity.
The basic components of a household hood:
The box body: supports the structure of the entire range hood, the wind deflector and the panel assembly are all mounted on the box body, and the volute, the illumination lamp, the motor, the wind wheel, the check valve and the like are also mounted on the box body.
Motor: It is the core part of the range hood, basically consisting of stator, rotor, front and rear cover, ball bearing and so on.
Wind wheel: It has a direct impact on the smoke exhaust effect and working performance of the range hood. The current wind wheel uses a centrifugal wind wheel, also known as a Chiba wind wheel.
Exhaust pipe: A passage device for the exhaust of flue gas.
Volute: Connect the check valve to the upper and connect the air deflector. The main reason is that the flue gas sucked by the wind wheel can be smoothly discharged by the exhaust pipe; at the same time, the wind wheel sucks the oil to the volute to play the role of collecting oil.
Check valve: It acts as a connection between the volute and the exhaust duct, and can prevent the wind from falling.
Air deflector, panel: The two combine to form the hood of the range hood, and at the same time play the role of collecting soot.
Soot collecting device: mostly composed of oil collecting box, exhaust pipe, oil collecting cup and oil guiding ring.
What are the classifications of household hoods?
1. According to the installation position, the range hood can be divided into three types: top suction type, side suction type and lower suction type, which are respectively located above the cooktop, side and below.
Top suction type: The suction force above the cooker is strong, and the dispersing phenomenon is easy to occur. The space above the stove is large, and the easy to clean head is more troublesome and has more styles, and the price ranges from 1000 to 3000.
Side suction type: The side smoke effect of the cooker is more ideal. The high smoke purifying rate takes up less space, there is no feeling of depression on the top of the head, and it is not easy to clean the head. It is less troublesome and has less noise; the noise is 2000~5000.
Down suction type: the smoke smoke suction effect under the cooker is excellent; the oil smoke does not take up the space of the person's face, saves the space above the cooktop and is easy to maintain. The price is high, the price is low, and the price is more than 5000.
2. According to the structure of the hood, the range hood can be divided into a flat cover type, a shallow cover type, a deep cover type, a spread wing type, a step type and a cabinet cover type.
Flat cover type: The hood is flat, beautiful in appearance and has a good smoking effect. Common in European style hoods.
Shallow hood type: The hood is very shallow, the smoking effect is general, and the smoke spillover is serious. Common in European style hoods.
Deep-cover type: including deep and deep cabinet type, with deep hood, used to accommodate soot that can't be sucked and drained, cushioning and avoiding a lot of fumes. Common in Chinese hoods.
Spreading wing type: The hood is unfolded during work, and the hood is automatically closed when it is not working; the shape is beautiful and the streamline is strong.
Cabinet type: form multiple smoking areas to improve the effect of oil smoke. Common in side suction range hoods.
Stepped: It consists of a windshield surrounded by four sides, which can effectively prevent the spread of soot. Seen in the down suction range hood.
How to choose a household hood?
1. Exhaust air volume: The exhaust air volume of the hood refers to the exhaust air volume per unit time of the hood when the static pressure is zero. Generally, the larger the air volume value, the stronger the ability of the hood to suck and drain the fumes. The national regulations require that the exhaust air volume of the range hood should be greater than or equal to 7 cubic meters per minute, while the exhaust volume of a typical range hood product can reach 13 to 15 cubic meters per minute. Therefore, if there is a high demand for the soot extraction capacity of the range hood, the product with a larger air volume value is selected when purchasing.
2. Wind pressure: The wind pressure of the range hood refers to the static pressure value when the air volume of the range hood is 7 cubic meters per minute. The greater the wind pressure value, the stronger the resistance of the range hood to winds. In the case of a long exhaust pipe, a product with a large wind pressure value can ensure that the fume is completely discharged. The national regulations require that the wind pressure of the hood should be greater than or equal to 80 Pa.
3. Noise: The noise of the range hood in the kitchen often makes many people who are cooking feel very annoyed. Noise refers to the sound of the hood at the rated voltage and rated frequency at the highest speed. Normally, noise is an important technical indicator for measuring the performance of the hood. Obviously, the noise of the hood is guaranteed under good performance. The smaller the value, the better. The national standard value is not more than 74dB.
4. Motor power: The suction force of the range hood depends on the power of the motor. The power of the hood motor on the market is generally between 180-220W. Relatively speaking, the higher the motor power, the better the smoking effect. But it is not to say that the bigger the motor power, the better. This needs to take into account the size of the kitchen soot. If the soot is not large, the power should not be chosen very large, otherwise it will cost electricity.
5. Panel material: Because the hood needs to be exposed to various types of fumes and corrosion every day, its panel material is also very important. Common hood products are mainly made of aluminum alloy, stainless steel and tempered glass. The strength of aluminum alloy material is low, it is easy to scratch in daily use, easy to lose luster; stainless steel has high strength, good finish and easy cleaning; tempered glass material is easy to clean, bright color, good plasticity, but large change in temperature difference There is a possibility of self-explosion.
6. Lighting function: If the hood is equipped with lighting device, the maximum power of the bulb should be indicated in the product parameters. At the same time, the lighting should have a lamp cover, and the lamp cover needs to have good light transmission and convenient replacement.
7. Cleaning function: It is also very important whether the hood is convenient for cleaning or whether it has its own cleaning function. The hood on the market began to add some cleaning functions, such as: the surface of the wind wheel is coated with oil-free coating; the box body adopts seamless design, double oil circuit design, and the inclined oil spill opening slot is added; the box body adopts easy-disassembly structure. Some also added an automatic cleaning device, adding the cleaning liquid to the inside of the liquid tank inside the machine, and pressing the switch can automatically flush the oil in the machine. Users can pay attention to this function when they purchase.
