Technical Field
[0001] The utility model relates to the technical field of range hoods, in particular to a range hood with an adjustable suction angle. Background Art
[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It is usually installed above the kitchen stove and can quickly remove the waste from stove combustion and the fumes that are harmful to the human body produced during cooking and discharge them outdoors. At the same time, it condenses and collects the fumes to reduce pollution, purify the air, and has a safety guarantee function of anti-toxicity and explosion-proof.
[0003] For example, in a range hood with the authorization announcement number CN217685240U, the above document installs an oil collecting box and an oil outlet assembly under the oil net, so that the oil slides into the oil collecting box, reducing the possibility of the oil dripping onto the countertop during use. At the same time, the oil in the oil collecting box is discharged through the oil outlet assembly, reducing the disassembly of the oil collecting box, and the oil can be directly discharged, reducing repeated disassembly during cleaning. However, the range hood in the above document occupies a large space above during use, which is easy to block the chef's head and hinder the chef's work. In addition, since the exhaust angle of the range hood is relatively single, the working angle of the range hood cannot be adjusted, resulting in low exhaust efficiency during operation of the range hood, and it is inconvenient for the staff to adjust the angle according to the use requirements.
[0004] At the same time, during the use of the range hood in the above-mentioned document, the control button of the range hood lacks a protective structure and cannot be protected. As a result, after the range hood has been used for a long time, part of the oil smoke will flow to the outside of the air during the flow of air, and it is easy to accumulate on the control button of the range hood. Over time, the control button is prone to adhesion between the button and the box due to the accumulation of oil stains, thereby affecting the control of the range hood by the control button.
