Problems solved by technology

[0003] Due to the huge oily fume from the kitchen chimney, the filter screen of the fan is covered with oily substances, which leads to the blockage of the filter screen, resulting in a decrease in air volume and a reduction in the suction effect of the oily fume. Manual and automatic replacement is required, which is troublesome.

Abstract

The invention discloses a kitchen pipeline smoke exhaust fan device. The kitchen pipeline smoke exhaust fan device structurally comprises a chimney, a flange plate and a fan, the chimney is connected with the fan through the flange plate, the fan comprises an outlet, a shell, a motor, an air inlet structure, a rotating shaft and blades, the rotating shaft is arranged in the middle of the shell, the blades are arranged on the side face of the rotating shaft, the rotating shaft is connected with the motor connected outside the shell, the shell is provided with the air inlet structure, the air inlet structure is connected with the chimney through the flange plate, and the outlet is formed in the top of the shell. The device has the beneficial effects that through the design, the power of the rotating shaft can be utilized to drive a filter screen to intermittently rotate at a small angle, the filter screen is convenient to wash, the filter screen is prevented from being blocked by oil stain, and through intermittent small-angle rotation, and the influence on air inlet of the filter screen is reduced.

Description

technical field [0001] The invention relates to the fan field, in particular to a kitchen duct smoke exhaust fan device. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine with many types, and the smoke exhaust fan is one of the more common ones. The smoke exhaust fan is a It is a machine that can quickly discharge the peculiar smell, high temperature and soot gas generated in the process of food processing in the kitchen. [0003] Due to the huge oily fume from the kitchen chimney, the filter screen of the fan is covered with oily substances, which leads to the blockage of the filter screen, resulting in a decrease in air volume and a reduction in the suction effect of the oily fume. Manual and automatic replacement is required, which is troublesome. Contents of the invention [0004] The main purpose of the present invention is to overcome the defi...
