Locking device of air inlet of range hood

Abstract

A locking device of an air inlet of a range hood comprises a drive device which is arranged on the inside of a panel of the range hood and an armature which is located at the lower end of a smoke blocking plate which is hinged with the air inlet of the panel. The locking device is characterized in that a fixing member is connected to the lower portion of the drive device, a permanent magnet is fixed on one side of the fixing member, which is close to the air inlet, the drive device is used for driving the fixing member to move, the fixing member and the armature are attached or loosened, and the smoke blocking plate is locked or opened. The locking device is simple in structure, easy to produce and assemble and capable of achieving the automatic locking and opening operation of the smoke blocking plate, preventing fume from flowing backwards caused by the fact that the smoke blocking plate is not closed tightly, cleaning the kitchen environment, preventing the smoke blocking plate from being opened under the condition of damage or failure of the drive device and guaranteeing the service life of the locking device and the range hood.

Description

technical field [0001] The invention relates to a range hood, in particular to a locking device for an air inlet of the range hood. Background technique [0002] The existing near-suction range hood usually includes a casing and a fan system arranged in the casing. The casing includes side panels on both sides and a panel on the side facing the stove and the user. The panel is provided with an air inlet for connecting the fan. After the system is powered on, the air inlet sucks the fume into the fan system and discharges it to the public flue. Most of today's near-suction range hoods, such as the side suction range hood disclosed in Chinese patent authorization announcement number CN201177306Y, have an air inlet that cannot be closed, so a lot of dust or bugs will enter the range hood, and The peculiar smell inside the range hood will also be emitted through the air inlet, and even the oil fume in the public flue will flow backwards, which will have a very bad impact on the...

AI Technical Summary

Problems solved by technology

There is no problem with the above-mentioned structure being used in other places or other home appliances, but when the structure is at the air inlet of the range hood, the range hood will stick oil stains to the electromagnetic chuck and armature during the long-term suction of range hood When the two are closed, the oil with a high viscosity will make the armature and the electromagnetic sucker stick firmly. When the range hood is started again, there is a situation that the smoke baffle cannot be turned up.
