Abstract

The invention relates to the field of lampblack flow guide, in particular to a volute for a kitchen ventilator and the kitchen ventilator. The volute for the kitchen ventilator is formed by buckling a front volute plate structure and a rear volute plate structure. The front volute plate structure comprises a volute front plate and a volute front coaming. The joint between the volute front plate and the volute front coaming is in curved face transition. The rear volute plate structure comprises a volute rear plate and a volute rear coaming. The joint between the volute rear plate and the volute rear coaming is in curved face transition. The front volute plate structure and the rear volute plate structure are oppositely arranged. The volute front coaming and the volute rear coaming are connected to form a coaming of the volute for the kitchen ventilator. The volute for the kitchen ventilator is defined by the front volute plate structure and the rear volute plate structure. The volute front plate and the volute front comaing of the front volute plate structure are in curved face transition, and the volute rear plate and the volute rear coaming of the rear volute plate structure are in curved face transition. By means of curved face transition, backflow of airflow inside the original volute can be effectively eliminated, the efficiency is improved, and noise is reduced.

Description

technical field [0001] The invention relates to the field of oil fume diversion, in particular to a volute for a range hood and a range hood. Background technique [0002] At present, the range hood has become a must-have appliance in the home kitchen. It absorbs the cooking fume and effectively discharges it to the outside, so that the kitchen is free from the trouble of the cooking fume. Among them, the volute of the range hood can collect the gas entering the impeller and discharge it to the outlet of the volute, and the volute plays the role of gas collection and pressure diffusion. In the range hood, the impeller and volute are the core components. The quality of its design plays a decisive role in the overall performance of the range hood. [0003] figure 1 It is the setting method of the metal volute at present, 9 is the original technical scheme volute, 90 is the volute coaming, 91 is the volute outlet flange, 92 is the front plate of the volute, 93 is the back pl...
