Axial extraction and lampblack separation integrated range hood

Abstract

The invention discloses an axial extraction and lampblack separation integrated range hood. The range hood comprises an outer cylinder wall (1), an oil collection tank (2) and a motor (5). The outer cylinder wall (1) and the oil collection tank (2) are coaxially arranged and provided with a cut-through hollow shaft (3). The oil collection tank (2) is arranged at the bottom of the range hood through fixing parts (6). The hollow shaft (3) is further internally provided with an annular impeller (4) connected with the motor (5) arranged in the hollow shaft (3). The annular impeller (4) is composedof arc-shaped blades (41) annularly arranged and a circular cover plate (42) at the top end. The hollow shaft is arranged in the center of the annular impeller. The motor (5) is connected with the circular cover plate (42) through a motor rotary shaft (51) to drive the arc-shaped blades (41) to rotate. The annular impeller rotates rapidly to form the centrifugal effect to extract and discharge lampblack. Compared with the prior art, the axial extraction and lampblack separation integrated range hood has the advantages of being strong in lampblack extraction and suction effect, high in whole-pressure efficiency, simple in structure, convenient to dismantle, clean and install and the like.

Description

technical field [0001] The invention relates to a range hood, in particular to an integrated range hood with the function of separating oil and smoke. Background technique [0002] Cooking fume contains a variety of toxic chemical components, which are extremely harmful to human health. In order to improve the dining and kitchen environment, the range hood has become one of the necessary household appliances in the kitchen. [0003] At present, the range hoods in our country are mainly of the external exhaust type, and the core components are motors and fans, and most of the fans are centrifugal. In order to prevent too much oil from entering the inside of the fan and causing problems such as difficulty in cleaning, filter devices such as oil screens are often installed at the inlet of the range hood or the fan inlet. And Oil Fume Separation Method", after separating and purifying the sucked oil fume, it enters the range hood or fan. [0004] Although the above-mentioned ...

AI Technical Summary

Problems solved by technology

[0006] The circulating range hood mentioned above has the advantages of being simple and beautiful, but because of its complex components, the installation space is limited, and it is accompanied by the risk of leakage of chemical reagents such as absorption and washing liquid to pollute the kitchen environment, especially for those with relatively large smoke volumes. In a large cooking environment, it is more difficult to ensure timely and effective removal of oil fume
