Extractor hood

Abstract

The invention discloses an extractor hood. The extractor hood comprises a fan cover, a smoke collecting cover, a flow-splitting plate and a center flow guide plate. A fan cavity is limited by the fancover. The fan cavity is internally provided with a fan. The smoke collecting cover is positioned below the fan cover, and limits a smoke collecting cavity communicated with the fan cavity. The smokecollecting cavity is provided with an oil and smoke inlet for collecting oil and smoke. The flow-splitting plate is installed in the fan cavity so that the fan cavity is divided to at least two sub-cavities distributed along an air inlet direction of the fan. The fan is installed in one of the sub-cavities. The center flow guide plate is installed in the sub-cavity provided with the fan, and the center flow guide plate is positioned below the fan and the flow-splitting plate. According to the extractor hood, because the fan cavity is internally provided with the flow-splitting plate and the center flow guide plate, vortex loss in the fan cavity is reduced, working efficiency of the extractor hood is improved, the filtering effect to oil and smoke air flow is improved, and working noise ofthe extractor hood is reduced.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a range hood. Background technique [0002] Range hoods are basically popular in the market at present, and the demand for range hoods in key cities is developing towards high-end, personalized and intelligent. The main key components that affect the actual effect of range hoods include fans, air ducts, and suction structures. Among them, the arrangement of fans in different installation positions, as well as the appearance and manufacturing process requirements of the flow channel structure and shape may lead to the inevitable uneven distribution of air in the flow process, affecting the distribution of speed and pressure, which in turn leads to The non-uniform distribution of the flow field near the suction port of the range hood is not conducive to the effect of the range hood. Therefore, the problem of local airflow loss can be improved through a reasonable flow channel st...

Problems solved by technology

Although the depth of the near-suction range hood is usually smaller than that of the top-suction type, in order to make up for the lack of smoke collection area at the top, the slope on the lower side is closer to the cooking utensils, which occupies the cooking space and also affects the user's operating experience.

For the integrated range hood, although the structure is compact, it will not occupy the cooking space, but it is difficult to achieve zero leakage of oil fume under the state of stir frying. If the air volume is increased to achieve the effect of zero leakage of oil fume, the noise will increase. The problem of high air volume, and the excessive air volume aggravates the consumption of gas
