Description

Technical Field

[0001] The utility model relates to the technical field of exhaust equipment, in particular to an intelligent kitchen exhaust system. Background Art

[0002] The kitchen is an essential place for making delicious food. The hygiene of the kitchen directly affects the hygiene of the food. When multiple stoves are working at the same time, the exhaust device plays a key role in the kitchen environment. In the case of poor ventilation, the kitchen fumes will be difficult to dissipate. The fumes contain carbon monoxide, carbon dioxide, and nitrogen oxides. Long-term inhalation affects human health. Existing kitchen exhaust devices all use simple cylindrical structures as exhaust ducts, which are not only noisy but also easy to accumulate oil stains. The large exhaust noise plus the working noise of the stove make the kitchen noisy and communication difficult.

[0003] In order to solve the above problems, the utility model patent with authorization announcement number CN219889022U discloses a silent exhaust device for kitchen, in which a fixed frame is fixedly connected to the side wall of the main exhaust duct, and a plurality of silent plates are fixedly connected to the fixed frame. The fixed frame fixes the silent plate to the inner wall of the main exhaust duct, and a smooth surface layer is fixedly bonded to the outer wall of the silent plate. The silent plate and the smooth surface layer are both in an arc shape convex toward the center of the main exhaust duct. A plurality of silent plates are connected end to end in sequence to form a wavy silent plate group. The noise generated when the smoke passes through the inner side of the main exhaust duct is reflected and refracted back and forth between the wavy silent plate group, and the sound energy is continuously consumed, which can effectively reduce the transmission of noise. The smooth surface layer has a smooth surface and is not easy to accumulate oil smoke. The outward convex shape has a relatively small contact surface with the smoke, and is also not easy to accumulate oil smoke.

[0004] However, when the device is used, as the use time increases, some impurities may adhere to the surface of the exhaust fan. Since the exhaust fan is fixed in the exhaust duct by bolts, it is inconvenient to disassemble and clean it. Utility Model Content
