A smoke baffle assembly and a range hood using the smoke baffle assembly

Abstract

The invention discloses a smoke baffle assembly, which includes a smoke baffle and a kinematic mechanism for driving the smoke baffle to turn over. The kinematic mechanism includes a driving mechanism and a hinge driven by the driving mechanism to rotate. The smoke baffle assembly also includes an opening assisting assembly. The opening aid assembly includes a pressure bottle containing a foam booster, a pressure switch that opens the pressure bottle when the thrust of the driving mechanism exceeds a threshold, and a first pipeline in fluid communication with the pressure bottle, the first pipeline is formed on one side facing the smoke baffle There is an outlet for the foam produced by the foam booster in the pressure bottle to flow out, thereby generating a thrust on the smoke baffle and assisting the opening of the smoke baffle. Also disclosed is a range hood applied with the above-mentioned smoke baffle assembly. Compared with the prior art, the present invention has the advantage that when the thrust of the driving mechanism is greater than the set threshold, the switch of the pressure bottle can be turned on, and the foam generated by the foam booster in the pressure bottle is used to generate a thrust on the smoke baffle through the pipeline, thereby assisting The driving mechanism realizes the opening of the smoke baffle to ensure the smooth opening of the smoke baffle.

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
