The invention discloses an inlet smoke gathering silencing device for a kitchen ventilator. A connecting device is positioned above a cavity and is of an annular hollow structure; an air inlet is formed in the lower part of the connecting device; an air outlet is formed in the upper part of the connecting device; an external thread is formed in the outer wall surface of the connecting device; thelower end cavity of the connecting device comprises an inner chamber and a plurality of distributary chambers; the inner chamber is separated from the distributary chambers through an annular wall surface; the inner chamber is formed in the wall surface, is of an annular structure, and is provided with an oil collecting ring, an inner chamber inlet, an oil returning channel, a compound silencing plate, a compound silencing plate air inlet and an inner chamber air outlet from bottom up; the distributary chambers are annularly arranged around the wall surface; the inlets of the distributary chambers are formed in the lower parts of the distributary chambers and are connected with the oil collecting ring; the outlets of the distributary chambers are connected with the outlet of the inner chamber and are positioned below the air inlet of the connecting device. Based on hydromechanics and the Coanda Effect, the inlet smoke gathering silencing device improves the grease separating degree atthe inlet of the kitchen ventilator and is combined with the noise reducing measures to lower the influence of the noise of the kitchen ventilator to a cooker.
Description
technical field [0001] The invention belongs to the field of range hoods and relates to an imported smoke collecting and silencing device for range hoods. Background technique [0002] As a commonly used household appliance, the range hood plays an important role in people's life, and the oil separation degree and noise of the range hood are important indicators for evaluating the performance of the range hood. [0003] Conventional upper-discharge range hoods use a filter structure with a single separation method. At the same time, the vertical intake of oil fume may easily lead to blockage of the mesh; in addition, long-term use of the range hood may easily cause grease to accumulate inside the range hood, affecting the smoke exhaust effect, seriously There is a risk of fire from time to time; in addition, there is no sound insulation measure at the entrance of the conventional upper range hood. Since the working platform of the range hood is close to the human ear, the wo...
