Range hood with oil fume separator

Abstract

The invention discloses a range hood with an oil fume separator. The range hood comprises a hollow range hood shell, wherein an air outlet and an air inlet are respectively formed in the upper end and the lower end of the range hood shell; an air flue communicating the air outlet with the air inlet is formed in the shell; a fan for sucking oil flue is arranged in the air passage. The range hood is characterized in that the oil fume separator is arranged at the air inlet; the fume separator comprises a plurality of rotating shafts rotating due to negative pressure generated by the rotation of the fan; a plurality of condensing sheets rotating together with the rotating shafts are arranged on each rotating shaft; an oil receiving box for receiving oil thrown off the condensing sheets is arranged on the range hood shell. The range hood can effectively realize fume separation, the oil is prevented from entering the interior of the range hood, a motor and an impeller inside the range hood are protected, the performance stability of the range hood is guaranteed, the service life of the range hood is prolonged, and meanwhile the conditions that the oil is easily collected on the wall surface and in the oil flue are greatly reduced.

Description

【Technical field】 [0001] The invention relates to kitchen fume exhaust equipment, in particular to a range hood with a fume separator. 【Background technique】 [0002] Due to the cooking habits of Chinese families, the kitchen usually produces a lot of oil fume, so the oil fume filter device of the range hood should not use the structure of the filter layer such as activated carbon, otherwise, the filtered oil will easily block the mesh and gaps, resulting in a sudden increase in the air volume of the range hood. Reduced, so that the oil fume function of the range hood is greatly reduced. Therefore, the oil fume filter device in the current range hood generally adopts two structures, one is a single-layer or double-layer filter screen structure with relatively coarse mesh holes, and the other is a filter plate structure with openings. [0003] No matter it is the oil fume filtering device of the above-mentioned first type or the second type of range hood, there is a big prob...

AI Technical Summary

Problems solved by technology

Although the cleaning cycle of the above first structure is longer, the oil fume is still easy to remain on the filter screen, resulting in an increase in wind resistance and a decrease in the air volume of the fan, which in turn affects the oil absorption performance of the range hood

For the second structure, although the cleaning of the oil fume filter itself has been well solved, the volute inside the range hood and the fan are still prone to residual oil fume, which will cause oil fume to accumulate on the volute and fan over time

If it is not cleaned in time, the operation of the fan of the range hood will not be as flexible as before, which will affect the air volume of the range hood, and the residue of oil fume will also cause a lot of noise, which will greatly affect the user's kitchen environment. The oil fume in the range hood is another very heavy work, which causes great inconvenience to the users.

In addition, these existing range hoods still contain a large amount of oil fume through the gas that enters the public flue through its air outlet and then is discharged into the atmosphere. The fume is exhausted into the atmosphere, which also pollutes the environment and affects people's health
