AI Technical Summary

Technical Problem

Traditional impeller blades have high resistance to airflow, resulting in reduced efficiency. The blade surface is not conducive to the adsorption and separation of oil fumes, and oil accumulates easily and is difficult to clean.

Method used

The blades are designed with streamlined shapes and are combined with auxiliary mounting components, including a first and second fixed plate arranged coaxially. The blade sides are streamlined, and the mounting housing is equipped with a shaft sleeve and auxiliary mounting components. The clamps are made of spring steel or stainless steel for easy installation of the impeller and the motor shaft.

Benefits of technology

It improves the efficiency of oil fume separation, reduces the accumulation of oil inside the impeller, reduces airflow resistance and energy loss, extends the impeller life, and simplifies the cleaning process.

Abstract

The utility model discloses a kind of impeller and extractor hood, belong to kitchen utensil field. To solve the problems of large air flow resistance of existing impeller blade, low efficiency and easy to accumulate oil. The utility model includes coaxially arranged first fixed sheet and second fixed sheet, the first fixed sheet is provided with a plurality of blades arranged around its axis between the second fixed sheet, wherein, blade side is streamline, the first fixed sheet is equipped with installation shell, and shaft sleeve and auxiliary installation component are set on installation shell. The technical scheme is by adopting streamline blade, effectively reduce air flow resistance, improve impeller operating efficiency and oil fume separation effect, reduce oil accumulation;At the same time, auxiliary installation component is convenient for the quick preliminary fixation of impeller on motor shaft, simplifies installation process.
