Smoke barrier assembly and range hood applying smoke barrier assembly

Abstract

The invention discloses a smoke barrier assembly. The smoke barrier assembly comprises a smoke barrier and a moving mechanism for driving the smoke barrier to turn over, wherein the moving mechanism comprises a driving mechanism and a hinge driven by the driving mechanism to rotate, the smoke barrier assembly further comprises an opening assisting assembly, the opening assisting assembly comprisesa pressure bottle containing a foaming agent, a pressure switch used for opening the pressure bottle when a pushing force of the driving mechanism exceeds a threshold value, and a first pipeline communicating with fluid of the pressure bottle, and an outlet is formed in one side, facing the smoke barrier, of the first pipeline, and foam generated by the foaming agent in the pressure bottle flowsout of the outlet, so that thrust is generated on the smoke barrier to assist in opening the smoke barrier. A range hood applying the smoke barrier assembly is further disclosed. Compared with the prior art, the smoke barrier assembly has the advantages that when the thrust of the driving mechanism is larger than the set threshold value, the pressure bottle switch can be turned on, the foam generated by the foaming agent in the pressure bottle generates the thrust on the smoke barrier through a pipeline, then the driving mechanism is assisted in achieving opening of the smoke barrier, and smooth opening of the smoke barrier is guaranteed.

Description

technical field [0001] The invention relates to a cooking fume purification device, in particular to a smoke baffle assembly and a range hood using the smoke baffle assembly. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. The range hood uses the principle of fluid dynamics to work, sucks and exhausts the range hood through a centrifugal fan installed inside the range hood, and uses a filter to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. [0003] Generally, range hoods include top suction type and side suction type. The side suction type range hood...

Problems solved by technology

However, when the range hood works for a certain period of time, a large amount of condensed oil will appear on the smoke baffle. If the ambient temperature is low or the user does not use the range hood frequently, after the smoke baffle is closed, the Condensed oil will bond the smoke baffle to the surface frame of the range hood. If the bonding area is large, the required force will exceed the rated value of the drive motor, which will cause the smoke baffle to always fail to open, seriously affecting the work of the range hood , affecting user experience

[0006] At present, for the performance improvement of the range hood, more attention is paid to the air volume and air pressure, and not much attention is paid to whether the smoke baffle can be opened normally. If the smoke baffle cannot be opened, professional maintenance personnel are often required to disassemble the machine for inspection, which greatly improves It shortens the maintenance time, reduces the utilization rate of after-sales resources, and causes great inconvenience to users
