Description

Fume exhaust fan

Technical Field

The utility model relates to the technical field of range hoods, in particular to a range hood.

Background

In the prior art, an oil screen of the European-style range hood is generally directly installed and fixed at a smoke collecting cover position at the bottom of a box body of the range hood and is used for intercepting rising smoke in a cooking process so as to achieve the effect of separating greasy dirt. Generally, the oil screen mounting position structure is that one side of the fume collecting hood is provided with a slot suitable for mounting the oil screen pins, and the other side is provided with screws or various quick-release fixing mechanisms. However, the installation mode can only ensure that the fixed ends of the screws or the quick-release mechanisms are firmly matched, and the installation ends of the plugging pin slots of the oil screen cannot be firmly matched. Because the production process of the plug pin slot needs reserved punching gaps, matching sizes and the like, the size of the plug pin of the fume collecting hood slot needs to be larger than that of the oil net, and therefore, after the oil net of the European-style range hood is assembled, the matching gaps are formed on the fixed side of the plug pin, so that the oil net is loose to install, and abnormal noise can occur during operation. In addition, as shown in fig. 1 and fig. 2, the plug connection causes a gap between the oil screen 200 and the inner wall of the fume collecting hood 120, so that fume invades from the gap, which causes abnormal oil path of the whole machine, and simultaneously causes aggregation of oil stains, and increases the risk of oil leakage.

Therefore, a range hood is needed to solve the above problems.
