Abstract

The embodiment of the application discloses a range hood, which comprises a machine body assembly and a spray assembly, wherein the spray assembly comprises a liquid supply pipe, a spray pipe and a first spray head, at least part of the spray pipe is arranged in the machine body assembly, the spray pipe is rotatably connected with the liquid supply pipe, and the first spray head is connected with the spray pipe. On the other hand, the liquid flow sprayed by the first spray nozzle has a certain impact force, and the rotation of the spray pipe can also enable the liquid flow sprayed by the first spray nozzle to have centrifugal force, so that the resultant force can be generated by the centrifugal force and the impact force, the cleaning effect of the liquid flow on the machine body component is more favorable, the removal of greasy dirt attached on the inner wall of the machine body component is particularly favorable, and the odor of the range hood is favorable.
