The invention relates to an oil fume exhaust machine having a function of prevention of hand and other things from pinching by a panel. The oil fume exhaust machine comprises a cabinet, a volute and a wind wheel, wherein the front end of the cabinet is provided with a smoke suction port, and an oil filtration screen is arranged between the smoke suction port and the volute. The oil fume exhaust machine is characterized in that both sides of the smoke suction port are symmetrically provided with linear guide rails, the guide rail is provided with a rack plate engaged with a drive gear, the drive gear is arranged on a drive motor, a panel is arranged outside the rack plate so as to be used for covering the smoke suction port, the drive motor is electrically connected with a control circuit, and the control circuit is further provided with an upper position limitation switch and a lower position limitation switch for controlling stroke of the panel, and an anti-pinching position limitation switch. The oil fume exhaust machine has the following beneficial effects that: a section of the anti-pinching gas can exist during the closing process of the panel to remind the user to pay attention to safety, and the gas is completely closed after being upward opened a certain distance so as to avoid injury.
Description
technical field [0001] The invention relates to a kitchen appliance, in particular to a range hood with a panel anti-pinch function. Background technique [0002] With the progress of human civilization, in the field of daily-use stoves and range hoods, the shielding, separation and discharge of oil fumes are becoming more and more difficult due to the improvement of the airtightness of modern living rooms and people's requirements for living environments. Among them, the deflector of the range hood is generally fixed on the panel, which not only takes up space in the kitchen, but also the smoking port is always open, which not only affects the appearance of the range hood, especially the range hood that has been used for a long time and has not been cleaned is even more serious. ; In modern urban housing, most of the public exhaust pipes are used, which is easy to cause oil fumes to flow backwards and pollute the indoor air. Chinese Patent No. 20101096655.2 also proposed a...
