Outward discharge and internal circulation range hood

Abstract

The invention discloses an outward discharge and internal circulation range hood, which comprises an air exhaust device installed in an oily fume exhaust chamber, wherein the air exhaust device comprises a shell, a shaded pole motor, a carbon box, an air channel, an outward discharge air hole and a wind deflector; the outward discharge air hole is formed in the side wall of the shell and communicated with the air channel; the wind deflector is installed on the outward discharge air hole; the shaded pole motor is arranged on the air channel of the shell; and the carbon box capable of filtering oily fume and peculiar smell is arranged at the lower end of the shaded pole motor. An exhaust guide pipe is not used for internal circulation discharge of the range hood disclosed by the invention; separated oily fume and peculiar smell are converted into clean air after being purified by entering the carbon box, and then discharged into a kitchen internal circulation process after being pressurized through the shaded pole motor; in the process of outward discharge, separated oily fume and peculiar smell are converted into clean air after being purified by entering the carbon box, and then discharged to the outdoor through the exhaust guide pipe after being pressurized through the shaded pole motor, therefore, the range hood is environment-friendly; furthermore, the trouble of detaching and cleaning the range hood can be avoided, the service life of the range hood is prolonged, and the cost is reduced.

Description

technical field [0001] The invention relates to a kitchen range hood, in particular to an external exhaust and internal circulation range hood. Background technique [0002] The range hood is a must-have item in the kitchen. The performance of the range hood directly affects the environment of the kitchen and the health of the user. Moreover, the range hood is easily polluted by the range hood and affects the service life of the range hood. Existing general range hoods directly discharge the oil fume into the atmosphere, and there is actually secondary pollution from the oil fume; there is another type of range hood that separates the oil fume and discharges it to the kitchen for circulation, but its structure is relatively It is complicated and the cost is too high; and the current range hoods are extremely single in performance. Contents of the invention [0003] The problem to be solved by the present invention is to provide a range hood with external exhaust and inter...
