Wind screen machine capable of facilitating removal of oily fume of ceiling type range hood

Abstract

The invention discloses a wind screen machine capable of facilitating removal of oily fume of a ceiling type range hood. Two L-shaped wind screen machines are symmetrically arranged and are used for surrounding the outer side of a gas stove which is placed on a stove table, wherein each L-shaped wind screen machine consists of a longitudinal blade-free fan and a transverse blade-free fan which are connected in series with a micro synchronous motor and are driven by the micro synchronous motor; each blade-free fan comprises a shell, a machine seat, a wind wheel and a conical gear; a conical gear mounted at the rear end of a wind turbine shaft of the longitudinal blade-free fan is engaged with a conical gear mounted at the front end of a wind turbine shaft of the transverse blade-free fan; the micro synchronous motor is mounted on the machine seat; the shell covers the wind wheel; a wind inlet crack hole is formed in the lower side of the shell; a wind outlet crack hole is formed in the upper side of the shell; the shell is capable of rotating for a certain angle around the wind turbine shaft; the working principle of the blade-free fans is as same as that of a blade-free fan; the wind enters by virtue of the air inlet crack hole in the outer side of the shell and blows out of the wind outlet crack hole in the upper side of the shell; the waste gas generated by combustion of the gas and the oily fume generated by frying dishes are upward blown up to the wind cover of the ceiling type range hood.

Description

Technical field: [0001] The invention relates to an air curtain machine for helping a top-suction range hood to suck and remove oil fumes. Background technique: [0002] In Patent No. 201120198236.2 "Air Curtain Machine Helping Top-suction Range Hoods to Absorb and Remove Oil Fumes", the blower is noisy and inefficient; it is necessary to use a conical air duct with a split air nozzle on the upper side, because the wind is from the conical air The large mouth end of the pipe blows in forward; therefore, when the wind blows out from the slit nozzle, there are two forces of forward and upward, that is to say, the wind blows out obliquely upward, and will not blow all the oil fume to the top suction type oil fume in the hood of the machine. Invention content: [0003] The present invention can overcome the defects of the above-mentioned patent No. 201120198236.2 "air curtain machine for helping top-suction range hood to absorb and remove oil fume". [0004] The present inve...
