Near-suction type oil smoke suction machine and matched oil smoke expelling device

Abstract

The invention discloses a near-suction type oil smoke suction machine and a matched oil smoke expelling device. The near-suction type oil smoke suction machine comprises an oil smoke suction blower, a casing, an air suction window, a filtering membrane, a stainless steel net, a spraying device, an oil collection groove and an electric control system. Window sashes which are upright and are mutually installed on the air suction window in parallel are hollow, and cold water or tap water, condensed oil spots and vapour are filled into the window sashes. The upper ends and the lower ends of the left side and the right side of the air suction window are respectively provided with two upper water pipes and two lower water pipes, the back face of the air suction window is provided with the filtering membrane which is supported by using the stainless steel net, and the spraying device is arranged in the casing above the filtering membrane and is used for scouring the filtering membrane and the window sashes of the air suction window. The oil smoke expelling device comprises a suction blower, a basic pipe, an air door, a positioning screw, a telescopic pipe and an air blowing pipe. Air blown out by the blower passes through the basic pipe and the air door on the basic pipe, then passes through the telescopic pipe and is blown out of a lip of the air blowing pipe, and oil smoke generated during stir-frying is blown to the air suction window and is sucked into the near-suction type oil smoke suction machine. The effects of oil smoke suction and oil filtration of the invention are greatly enhanced.

Description

Technical field: [0001] The invention relates to a near-suction range hood and a matching device for driving away the lampblack. Background technique: [0002] Existing near-suction range hoods allow oil fume to wind several bends on the window leaf when it enters the suction window, or use metal mesh to block oil fume, and oil stains will condense on the window leaf or metal mesh after encountering cold window leaf or metal mesh , and then flow into the oil collection tank to achieve the purpose of filtering oil pollution. This oil filtering method will prevent the oil fume from entering the suction window; at the same time, the specific heat of the stainless steel window and mesh is very small. The window and net will be heated to a temperature similar to that of the oil fume, and the stainless steel window and net will no longer have the function of condensing oil and will no longer filter oil. The window and metal net with oil on the surface The oil filtering effect wil...

AI Technical Summary

Problems solved by technology

The oil that has not been filtered out enters the range hood and is thrown onto the inner wall of the range hood by the impeller of the range hood rotating at high speed, and some of the oil is stained on the impeller, which affects the suction of the range hood.

Due to the above reasons, after using this range hood for a period of time, it will not be able to suck all the cooking fumes into the range hood. At present, this type of range hood is facing the situation of being eliminated by Tao.
