Locking device of smoke barrier at air inlet of range hood

Abstract

The invention provides a locking device of a smoke barrier at an air inlet of a range hood. The locking device comprises a driving device and a buckle, wherein the driving device is arranged at inside of a panel of the range hood; the buckle is positioned at the lower end of the smoke barrier which is hinged on the air inlet of the panel; and the locking device is characterized in that a fixing member is connected to the lower part of the driving device; and the driving device drives the fixing member to move so that the fixing member is buckled with the buckle or loosened so as to lock or open the smoke barrier. The locking device of the smoke barrier at the air inlet of the range hood is simple in structure and convenient to produce and assemble; and through the locking device, the automatic locking and open operation of the smoke barrier can be realized; the oil fume backflow caused by untight closing of the smoke barrier can be prevented; the environment of a kitchen is cleaned; the situation that the locking device cannot be used caused by oil pollution can be avoided; and the service life of the locking device and the service life of the range hood are guaranteed.

Description

technical field [0001] The invention relates to a range hood, in particular to a locking device for a smoke baffle at 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...

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.
