What's the difference between a range hood and a range hood

What's the difference between a range hood and a range hood? A range hood is an important household appliance. In order to ensure the air quality in the kitchen, many people are equipped with a range hood. Let's see what's the difference between a range hood and a range hood. What's the difference between a range hood and a range hood? 1

1, power is different

The power of a smoke ventilator is 211W, and that of an exhaust fan is only 11 W-51 W..

2. Different uses

The purpose of exhaust is to remove indoor dirty air and adjust temperature, humidity and sensory effect. Exhaust fans are widely used in homes and public places. Smoking machine is used in kitchen to smoke oil fume.

3. The working principle is different

There are three ventilation modes of exhaust fan: exhaust type, suction type and combined type. Exhaust type enters air from natural air inlet and exhausts dirty air through exhaust fan; Suction type draws in fresh air through a ventilator.

the principle of the exhaust type of the range hood is to suck the oil fume in the room, separate the oil mist and exhaust it to the outside through the pipeline. The exhaust range hood is installed on the upper part of the stove, and the impeller in the volute is driven by the motor in the machine body to rotate, forming a certain negative pressure in the air inlet area and draining through the smoke collection cavity.

Extended information:

Although the exhaust fan can remove most of the oil fume in the kitchen, it is unable to solve the pollution of the oil fume generated in cooking to the whole kitchen. The oil fume generated in cooking contains many substances harmful to human body. If people work in a room full of oil fume for a long time, many diseases will occur.

range hood, also known as range hood, is a kind of kitchen appliance for purifying the kitchen environment. It is installed above the kitchen stove, which can quickly pump away the waste burned by the stove and the oil fume harmful to human body generated in the cooking process, and discharge it outdoors, thus reducing pollution, purifying the air, and having the functions of anti-virus and anti-explosion.

range hoods can be divided into axial flow and centrifugal type. Axial flow fans are generally equipped with shallow hoods, which have large air volume and small wind pressure; Centrifugal fan has high wind pressure. The range hoods sold in the market are mainly centrifugal, so there is not much room for choice in the model. Generally, they are outdoor and equipped with centrifugal fans.

according to the structural form, there are two types of range hoods: deep type and thin type, and there are also semi-deep type, European type and pull type. There are three types of range hoods in the market: thin, deep and cabinet. What's the difference between a range hood and a range hood? 2

For non-professionals, they can't tell the difference between a fume purifier and a range hood. After all, both the fume purifier and the range hood sound like they are discharging kitchen fumes, but they are not. Oil fume purifier and range hood are essentially different products, and there are essential differences between them in terms of appearance and purification efficiency.

In terms of structure and function, the range hood is more like an exhaust fan, but the oil fume is pumped from one place to another to prevent the oil fume from harming human body. Generally speaking, there are two or more range hood systems behind the range hood, which can generate great suction. If the lampblack is pumped out in time, the work will be completed and the lampblack cannot be purified. The discharged oil fume will still be harmful to human body and environment.

generally, the oil fume purifier does not work alone. The lampblack purifier will be used in conjunction with the hood, air duct and fan. The lampblack is collected through the hood, sucked into the lampblack purifier through the fan, and then adsorbed and ionized in the lampblack purifier, thereby removing harmful substances in the lampblack. This is the purification effect. The discharged air will not pollute the surrounding environment and human body. At present, the purification efficiency of general oil fume purifiers on the market can reach more than 91%, and some can reach more than 98%.

Application fields of range hoods and oil fume purifiers:

Range hoods are generally used in family kitchens, which are suitable for a small amount of oil fume and can be directly discharged into the surrounding environment without filtering.

the oil fume purifier is suitable for large-scale exhaust occasions, such as large restaurants, hotel kitchens, factory kitchens, etc., where oil fume needs to be filtered and purified, and the purified air is discharged into the air. The user department is supervised by the environmental protection department, and it must be pollution-free to the surrounding environment after treatment.

to sum up, no matter from the structural function or application field, the oil fume purifier is used to purify oil fume, which is suitable for commercial restaurants, while the range hood is more suitable for domestic kitchens.

Maybe in the near future, the domestic range hood will also be upgraded to the function of oil fume purification, which is also possible. Weidun has been committed to the research and development of an all-in-one hood and oil fume purification machine, which can be used by small catering users and civil kitchens. Local environmental protection is not only for enterprises, but also for every family, and environmental protection should start with everyone.

What are the key switches for the range hood

1. If you want to start the range hood, you need to operate it through different key switches. There is a start, which means you can open it by pressing it. There are also different buttons, which will display Chinese, some are high speed, some are low speed, and there are function keys for lighting demand, stop and cleaning.

2. In specific use, we can combine the product manual. Some range hoods have other functions on the function panel, such as delayed shutdown or wind adjustment, and some have the function of washing keys with steam hot water.

3, combined with the product manual to run, press it once, the indicator light will light up, and press it again to turn it off directly. What's the difference between a range hood and a range hood? 3

1. The difference between a range hood and a range hood

A range hood, also known as a range hood, is a kitchen appliance that purifies the kitchen environment. Installed above the range of healthy and energy-saving range hood in the kitchen, it can quickly discharge the waste burned by the range and the oil fume harmful to human body in the cooking process, and discharge it outdoors, reducing pollution and purifying the air, which has the safety guarantee function of anti-virus and explosion-proof.

range hoods need to be cleaned regularly. Simple cleaning can't deal with oil stains. To clean range hoods, professional cleaning agents must be used. The range hood is made of high-strength materials, which is very simple to operate, low in irritability and good in oil smoke absorption.
