Project Background

Kitchen oil fume is the cooking oil and food produced after high-temperature heating. High-temperature cooking is a unique cooking habit in my country, so the kitchen fume formed during high-temperature cooking has become one of the air pollutants in the indoor living environment in my country.

In recent years, with the improvement of people’s living standards and the development of the catering industry, the consumption of edible oil has continued to increase, and the health hazards of cooking oil fume have received more and more attention. The application of electronic products in people’s lives is becoming wider and wider. In the era of smart homes, it is naturally better to have a Range hood with intelligent functions. Range hoods have become common household appliances in the kitchen.

If a Range hood is used in the kitchen, the cooking fume in the kitchen can be well controlled, and the switch can be automatically switched according to the size of the cooking fume to control the wind to perform the cooking fume work, thereby achieving energy saving. The Range hood is easy to clean can efficiently absorb oil fume and peculiar smell, and will not remain in the kitchen to achieve a smokeless effect.

At the same time, we can intelligently control the Range hood, which uses intelligent hand control. We can easily control the switch function of the Range hood with a wave of hands in front of the control panel. Besides, the Range hood can intelligently link the cooktop. When the user starts the cooker, the Range hood can also be turned on automatically, making cooking easy and fun.

The Main Components of the Kitchen Hood

The Range hood is mainly composed of casing, air duct, fan, check valve, oil collecting and draining device, lighting device, power switch, and power cord. Simply tell you about the internal structure of the Range hood:

1. Chassis: It consists of two parts: a shell and a panel; it is made of cold-rolled thin steel plate surface spray treatment, which not only has a smooth and beautiful appearance but also has high durability and is easy to clean;
2. Motor: the motor is the core part of the Range hood;
3. Windwheel: centrifugal wind wheel: its diameter is 220mm-240mm. It is stamped from silicon alloy aluminum sheet, which is durable and has good dynamic balance performance;
4. Air duct: It is a channel for exhausting smoke; it is made of cold-rolled sheet steel with a plastic spray treatment. The rationality of the air duct structure determines the exhaust air volume and noise of the entire Range hood;
5. Check valve: It is made of plastic; its function is to prevent the backflow of flue gas;
6. Smoke exhaust device; it is composed of oil collecting box, smoke exhaust pipe, oil collecting cup, and oil guide ring;
7. Lighting device: Ordinary Chinese style machine uses 15~40W incandescent screw bulb, European style machine, near suction style uses cold light source lamp, and there is a detachable transparent plexiglass sheet outside to seal the lamp to avoid fume contamination and corrosion during cooking Lamps ensure electrical safety;
8. Power switch: use a light touch switch or mechanical switch to control the working state.

The Working Principle of Intelligent Kitchen Ventilator

The DC variable frequency motor in the Range hood adopts the FOC algorithm, the maximum static pressure can reach 900Pa, and the maximal air volume can be up to 23m3/min. It has increased its oil fume absorption and exhaust performance. Besides, it adopts creative source point low suction and upper discharge technology to absorb oil fume at a close distance from the source point of oil fume generation, which largely controls the spread of oil fume, and at the same time. It sucks more oil fume and makes the cooking environment cleaner and safer.

Timed automatic dry cleaning design, no need to worry about oily dirt, and automatically bid farewell to greasy. The impeller adopts the design of lotus leaf bionics non-stick technology. Intelligent dry cleaning realizes the automatic forward and reverse rotation of the impeller through the motor and uses the positive and negative eccentricity and the emergency stop to throw the oil to ensure that the interior is completely non-stick.

During the operation of the Range hood, we only need to press and hold the clean button for three seconds to immediately enter the dry cleaning function. After the Range, the hood works continuously for 0.5 hours, and we press the power button to enter the dry cleaning function. After the Range hood works for two hours, it will enter the automatic cleaning state when it enters the automatic shutdown without any operation, which is very worry-free and labor-saving.

The Suitable Motor for the Smart Kitchen Hood

For the intelligent kitchen ventilator, we recommend using this DC motor (RF-520TB-17370B), because it has the characteristics of low noise, high Torque, high performance, and long life. Of course, we can also according to the performance requirements of customers to provide a comprehensive evaluation of the motor and customize it.

Kinmore Motor has more than 20 years of experience in the customization of smart home motors. We have accumulated a huge database of motor prototypes in the application of intelligent Range hoods for customer reference. At the same time, we can quickly customize motor solutions that meet the requirements of customers and are suppliers and manufacturers of motor solutions.
