Range hood with oval-shape air inlet

Abstract

The invention discloses a range hood with an oval-shape air inlet. The range hood with the oval-shape air inlet comprises a range hood main machine (4). The range hood main machine (4) is provided with an air inlet structure. The air inlet structure comprises an internal smoke deflector (2) and an external smoke deflector (3). An air inlet (5) in an oval shape is formed in the external smoke deflector (3). According to the range hood with the oval-shape air inlet, the air inlet is arranged to be the oval shape; compared with a traditional air inlet, the oval-shape air inlet has smaller flow channel resistance and better smoke sucking effect; in the meantime, noise is reduced; and in addition, cooking fumes which cannot be sucked in in time can be stored temporarily, and dispersing of cooking fumes caused by a large quantity of momentary cooking fumes is prevented.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with an oval air inlet. Background technique [0002] In the prior art, range hoods use negative pressure suction to absorb oily fumes. The air inlets are generally circular, but the smoking range of circular air inlets is too small, and the oil fume is easy to disperse. Some people use rectangular air inlets, but rectangular air inlets The air inlet area of ​​the tuyere is too large and the suction is small. [0003] The specific defects are as follows: [0004] 1. The effect of collecting smoke is poor, the smoking range of the circular air inlet is too small, and the oily smoke is easy to disperse; [0005] 2. The noise is too loud, generally 70dB~73dB; [0006] 3. Domestic stoves are mainly binocular. When traditional range hoods are aimed at binocular stoves and two stoves at the same time, there will be some interference at the air inlet of the oil fume and oil su...

AI Technical Summary

Problems solved by technology

[0004] 1. The effect of collecting smoke is poor, the smoking range of the circular air inlet is too small, and the oily smoke is easy to disperse;

[0005] 2. The noise is too loud, generally 70dB~73dB;

[0006] 3. Domestic stoves are mainly binocular. When traditional range hoods are aimed at binocular stoves and two stoves at the same time, there will be some interference at the air inlet of the oil fume and oil suction, resulting in excessive resistance at the air inlet, and it is difficult to exhaust the oil fume;

[0008] 5. Due to the difficulty of exhausting the lampblack and the high power of the motor, the relative working time of the range hood is relatively long, resulting in a large energy consumption;

[0009] 6. When the oily fumes pass over the face and nose, the human respiratory system will inhale excessive residual oily fumes during the cooking process, which can easily lead to respiratory diseases and endanger human health and safety
