Extractor hood panel structure

Abstract

The invention relates to an extractor hood panel structure which comprises a panel frame installed on a machine box, and a smoke blocking screen is rotatably connected to the panel frame. The extractor hood panel structure is characterized in that the panel frame is furthermore provided with a shield plate capable of sliding along the surface of the panel frame; a drive device is in drive connection with a first transmission assembly and the smoke blocking screen; the drive device and the first transmission assembly are both arranged in a space separated from a lampblack channel; and the first transmission assembly is in drive connection with the shield plate. Compared with the prior art, by means of the extractor hood panel structure, the effective air inlet area can be changed according to requirements, the position of an air inlet is moved downwards, negative pressure and the air speed of the air inlet of an extractor hood are reasonably distributed, air volume, air pressure and whole-pressure efficiency are increased, and the smoke absorption effect of the extractor hood is improved; and meanwhile, the drive device and the transmission assembly are arranged to be separated from the lampblack channel, contamination of oil stains is avoided, and neat appearance of the extractor hood can be maintained.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a panel structure of the range hood. Background technique [0002] In order to prevent oily fume gas from pouring back into the air, keep the appearance of the range hood clean, and enhance the effect of suction and exhaust, people have developed a range hood that can automatically open and close the smoke screen. When the range hood is working, the smoke screen is opened, which can effectively block the fume from escaping, and when the range hood is not working, the smoke screen is closed. [0003] As disclosed in CN201210230513.2 "A Range Hood with Automatic Opening and Closing of Smoke Screen", it includes a cabinet and a fan system installed in the cabinet. The cabinet includes a panel facing the stove, and the panel is equipped with a The air outlet and the smoke screen matching the size of the air inlet are hinged on the upper end of the air inlet through a rotating hinge. An el...

[0004] Another example is CN204063212U disclosed "opening and closing type range hood panel mechanism". The panel mechanism can effectively block the oil fume in the public flue from entering the kitchen through the smoking port. When the range hood is turned on, the glass panel slides a certain distance to open the air inlet of the hood. However, the panel mechanism slides in par
