Embodiment Construction
[0019] like Figures 1 to 6 As shown in the figure, an automatic lift closed range hood includes a body 2, a fan and an automatic lift closure device. A filter screen is installed at the air inlet of the body 2, and an oil cup is arranged below the filter screen. The fan is formed by a volute casing. 3. The impeller 5 and the motor 6 are formed inside the volute 3. The volute 3 includes a volute portion 301 and an upper side plate 302 and a lower side plate 303 respectively arranged at the upper and lower bottoms of the volute portion 301. 302 is connected with the motor 6, the lower side plate 303 is provided with a smoke inlet 7, the impeller 5 is installed in the volute 3 in a way that its axial direction is perpendicular to the side plate, and the volute portion 301 is One side is extended with a smoke outlet pipe 4, the flue of the smoke outlet pipe 4 is arranged in a spiral and ascending manner, the inner wall of the smoke outlet pipe 4 is fitted with the volute 3, and t...

Abstract
The invention discloses an automatic-elevation closed range hood, comprising a range hood body, a fan and an automatic-elevation closing device, wherein an air inlet of the range hood body is provided with a filter screen, an oil cup is arranged below the filter screen, the fan is composed of a volute, an impeller arranged inside the volute and a motor, the volute comprises a volute part, an upper side plate and a lower side plate, the upper side plate and the lower side plate are arranged on the top and the bottom of the volute part respectively, the upper side plate is in matched connection with the motor, the lower side plate is provided with a fume inlet, the impeller is arranged in the volute in a manner of being vertical to the side plates, one side of the volute part is provided with a fume outlet tube in an extension manner, and a flue of the fume outlet tube is arranged in a spiral climb manner. According to the invention, not only can an eddy phenomenon generated by wind inside the volute be eliminated, but also vibrations and noise of the fan during working can further be reduced, and meanwhile, no dead angle is left during cleaning so that complete cleaning is realized; and the range hood is simple in structure, stable in operation and small in vibration, achieves the effect of sealing, converging and directly discharging oily fume, and is rapid and complete in fume exhaust, low in cost and free from dead angle during cleaning.
Description
technical field [0001] The invention relates to a kitchen range hood, in particular to an automatic lift closed type range hood. Background technique [0002] In the food processing in the field of gourmet food, frying, frying, cooking and frying account for a large proportion. Therefore, the oil fumes in the Chinese kitchen are very large, which can easily make the kitchen environment greasy and difficult to clean. Harmful substances to the human body, people work in an environment full of oil fume for a long time, may lead to the occurrence of diseases, and a range hood is a relatively popular kitchen electrical equipment used to discharge the oil fume generated during the cooking process of the stove. In the process of exhausting the flue gas, the range hood performs a process of oil and gas separation to avoid the oil-containing gas directly entering the atmosphere and causing pollution. During this process, the oil and gas first pass through a layer of filter screen, an...
