A magnetic gear variable speed oil fume separation structure and range hood

Abstract

The invention discloses a magnetic gear variable speed oil fume separation structure and a range hood. The magnetic gear variable speed oil fume separation structure includes: a rotating oil separator ring, a magnetic gear speed change mechanism, a blower fan and a motor; the magnetic gear speed change mechanism includes an inner rotor assembly, an intermediate stator assembly and an outer rotor assembly; the intermediate stator assembly is arranged between the inner rotor assembly and the outer rotor assembly, the outer rotor assembly and the inner rotor assembly rotate in opposite directions, and the rotation speed of the outer rotor assembly is greater than the rotation speed of the inner rotor assembly; the inner rotor assembly The rotor assembly, the blower fan and the motor shaft rotate in the same direction and at the same speed; the rotating oil separator ring and the outer rotor assembly rotate in the same direction and at the same speed. The invention realizes the speed-up transformation from the low-speed motor shaft to the high-speed rotating oil-separating ring in a non-contact manner. The high-speed rotating oil-separating ring can capture and shake off the grease particles more efficiently by virtue of its stronger centrifugal force, which is extremely efficient. It greatly improves the grease separation rate and the internal cleanliness of the range hood.

Description

technical field [0001] The invention belongs to the technical field of range hoods, and more particularly, relates to a magnetic gear shifting type range hood separation structure and range hoods. Background technique [0002] With the improvement of people's living standards, the internal cleanliness and working noise of range hood products have become two important performance evaluation indicators in the field of range hood products in addition to the effect of absorbing range hood. At present, in order to ensure the cleanliness and work efficiency of the components inside the range hood, such as the blower fan and the motor, the existing range hood products are equipped with a fume separation device at the air inlet to block large particles such as grease and water particles inside the separation device. And filtered through the oil tank, so as to achieve effective separation of grease particles and oil fume gas. [0003] At present, there are three common technical sol...

Problems solved by technology

In addition, since the rotating oil-separating ring is directly connected to the blower fan or the motor shaft, the rotating oil-separating ring will cause unbalanced disturbances, which will seriously affect the dynamic balance of the latter two, and it is very likely to generate large noise and reduce user comfort.
