Description

Range hood with built-in soundproofing panel

technical field

The utility model relates to the field of kitchen equipment, in particular to a range hood.

Background technique

The range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the healthy and energy-saving range hood stove in the kitchen. It can quickly take away the waste burned by the stove and the oil fume harmful to the human body produced during the cooking process, and discharge it to the outside, reduce pollution, purify the air, and have anti-virus and explosion-proof safety guarantees. effect. Range hoods have not been in the kitchen of ordinary Chinese families for a long time. Early home kitchen smoke exhaust work was done by exhaust fans. Although the exhaust fan can get rid of most of the oily fumes in the kitchen, it is unable to solve the pollution of the entire kitchen by the oily fumes generated during cooking. The cooking fume contains many substances harmful to the human body. If people work in a room full of fumes for a long time, it will cause many diseases.

For the Chinese, the dietary structure of Chinese people is different from that of Westerners, so the variety, style and arrangement of kitchen utensils in the kitchen are very different from those of Western countries. In Chinese food processing, frying, frying, cooking , frying occupies a large proportion, resulting in a lot of oil fume in the Chinese kitchen, and it is easy to make the kitchen environment greasy and difficult to clean. Therefore, the range hood has become a "powerful weapon" to change the kitchen environment. It changes the kitchen environment and reduces the damage caused by oil fume to the kitchen environment and human health. Range hood can be described as the "killer" of oil fume.

Existing range hoods realize the work of extracting fume through negative pressure generated by the high-speed rotation of the wind wheel, so the noise is very loud during operation, and it is not practical in some fields that require noise.

Contents of the invention

The technical problem to be solved by the utility model is to provide a range hood with a built-in sound insulation board. The range hood divides the casing into two parts with a sound insulation board, and the air extraction system that generates noise is arranged above the sound insulation board, which improves the extraction efficiency. Quiet performance of range hood.

The utility model is realized in the following way: a range hood with a built-in sound insulation board includes a casing, a filter screen, an oil cup, an air extraction system and a sound insulation board, and the sound insulation board is horizontally arranged in the casing to divide the casing into The upper and lower spaces, the air extraction system is installed in the upper space of the casing, an air inlet is opened in the middle of the bottom of the casing, the filter screen is covered on the air inlet of the casing, and the oil cup is installed on the At the center of the bottom of the filter screen, the suction system passes through the sound insulation board through the pipeline and communicates with the air inlet.

The air extraction system includes a wind guide ring, a wind wheel, a motor and a flue, the flue is fixedly installed on the casing, the motor is fixedly installed on the flue, and the wind wheel is fixedly installed on the output shaft of the motor Above, the wind guide ring is arranged between the filter screen and the wind wheel.

The wind wheel is a dry wing turbine.

An operation panel is arranged on the casing.

The bottom of the casing is provided with an illuminating lamp.

The lighting lamp is an LED lamp group, and the lighting lamp is covered with a transparent shield.

The range hood with built-in sound insulation board of the utility model divides the casing into two parts with the sound insulation board, and the exhaust system that generates noise is arranged above the sound insulation board, and the noise emitted is absorbed by the sound insulation board, so that the chef located under the range hood The sound from the exhaust system will not be heard, which improves the quiet performance of the range hood.
