Variable frequency range hood

Abstract

The invention discloses a variable frequency range hood. The variable frequency range hood comprises a body. The inner wall of the body is connected with a sealing door, and a first filter net is arranged in the position, close to the back side of the sealing door, in the inner wall of the body. An oil sink is mounted on the front surface of the body, and a button is embedded in the position, close to the position above the first filter net, in the front surface of the body. A bellows is fixed to the top end of the body, a first servo motor is mounted inside the body, and a slide block is fixed to the rear surface of the body. According to the variable frequency range hood, by arranging electro-hydraulic push rods, a fixing barrel and a sleeve, the electro-hydraulic push rods drive the sleeve to slide up and down on the outer surface of the fixing barrel, meanwhile, the body slides in front of the fixing plate through slide blocks and slide grooves, the mounting height of the range hood can be adjusted according to habits of a user, and the problem that the mounting height fails to be adjusted according to the habits of the user is effectively solved.

Description

technical field [0001] The invention relates to the field of frequency conversion range hoods, in particular to a frequency conversion range hood. Background technique [0002] The range hood, also known as the range hood, is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove, and can quickly suck away the waste burned by the stove and the oily fume that is harmful to the human body during the cooking process, and discharge it outside. It reduces pollution, purifies the air, and has the function of anti-virus and explosion-proof safety guarantee. [0003] However, the frequency conversion range hoods currently on the market cannot further improve the efficiency of the range hoods, resulting in insufficient power for the range hoods when inhaling the range hoods, resulting in that the range hoods cannot be sucked cleanly, and the current frequency conversion range hoods cannot be removed after installation. Adjusting the instal...

Problems solved by technology

[0003] However, the frequency conversion range hoods currently on the market cannot further improve the efficiency of the range hoods, resulting in insufficient power for the range hoods when inhaling the range hoods, resulting in that the range hoods cannot be sucked cleanly, and the current frequency conversion range hoods cannot be removed after installation. Adjusting the installation height makes it impossible to adjust the installation height according to the user's habits, and it is impossible to collect the grease accumulated inside it, resulting in too much grease accumulation to block the sleeve
