A range hood, also known as a range hood, is a kitchen electrical appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly remove the waste from the stove and the harmful oil fumes generated during the cooking process, and discharge them outdoors. At the same time, it condenses and collects the oil fumes, reducing pollution, purifying the air, and has a safety guarantee function of gas prevention and explosion prevention. The range hood needs to be cleaned regularly. Simple cleaning cannot remove oil stains, and professional cleaning agents must be used to clean the range hood p>
Equipment structure
The range hood mainly consists of a casing, air duct, fan, check valve, oil collection and drainage device, lighting device, power switch, and power cord.
. The casing consists of a shell and a panel, which are made of cold-rolled thin steel plate with a surface sprayed with plastic. It not only has a smooth and clean appearance, but also has high durability and is easy to clean. The motor is the core part of the range hood, using a fully enclosed single-phase capacitor operated asynchronous motor; The iron shell is fully enclosed, and the motor bearing is a double row ball bearing with an insulation level of E-pole insulation. The capacity of the starting capacitor is about 4 microfactors. The wind turbine adopts a centrifugal wind turbine. Its diameter is 220mm/240mm. Made of silicon alloy aluminum sheet stamping, durable and unchanged, with good dynamic balance performance. The air duct is a passage for smoke, made of cold-rolled steel sheet surface sprayed with plastic. The rationality of the air duct structure determines the exhaust air volume and noise of the entire range hood. The check valve is made of plastic to prevent the backflow of smoke. The smoke exhaust device consists of an oil collection box, smoke exhaust pipe, oil collection cup, and oil guide ring. The lighting device for ordinary Chinese machines uses 15-40W incandescent screw shaped bulbs: for European machines and near suction machines, cold light source lamps are used, with a detachable transparent organic glass sheet on the outside to seal the lamps and avoid oil smoke contamination and corrosion during cooking, ensuring electrical safety. The power switch adopts a touch switch or mechanical switch to control the working state P>Function of testing report:
