Abstract

The invention relates to the field of kitchen utensils, and aims at providing a side suction type extractor hood noise reduction device. The side suction type extractor hood noise reduction device comprises an exhaust fume collecting hood provided with an air inlet opening, and further comprises an air stopping ring arranged at an inlet of the air inlet opening and connected with the exhaust fume collecting hood and a noise reduction air guide plate assembly; and the noise reduction air guide plate assembly comprises an air guide ring, a noise absorption and noise reduction ring and a transparent air guide plate, wherein the air guide ring is provided with noise reduction hole sets, the back end of the air guide ring is detachably connected with the air stopping ring, and the transparent air guide plate presses the noise absorption and noise reduction ring and is connected with the air guide ring. The side suction type extractor hood noise reduction device is good in noise reduction effect.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to a side suction type range hood noise reduction device. Background technique [0002] The side-suction range hood sucks the oil fume from the upper back to improve the operating environment and reduce the height requirements for the kitchen; the invention of Chinese patent application number CN CN201310647938.8 discloses a range hood noise reduction device, including a smoke exhaust pipe , sponge and regenerated rubber, the noise reduction device is composed of sponges and regenerated rubber arranged in sequence, wrapped outside the smoke exhaust pipe, the device has a relatively high absorption frequency, and can basically absorb the middle and low frequency noise generated by the vibration of the smoke pipe, greatly reducing Range hood noise. The range hood noise reduction device used for side suction range hoods has the disadvantage of poor noise reduction effect. Therefore, de...
