Top suction type range hood of novel oil screens

Abstract

The invention discloses a top suction type range hood of novel oil screens. The top suction type range hood comprises a box body and a smoke collection panel, wherein a smoke collection opening is formed in the smoke collection panel; an upper oil screen and a lower oil screen are mounted on the smoke collection opening; the upper oil screen and the lower oil screen are convex cover bodies formed by stretching the smoke collection opening in a direction to the box body; a smoke collection concave cavity is formed in a convex cover body; the smoke collection panel is tilted, so that the convex cover bodies are obliquely mounted on the smoke collection opening; a hollow oil guide framework is mounted at the edge of the smoke collection opening; an oil guide groove matched with the edges of the oil screens is formed in the oil guide framework; the edges at lower positions of the convex cover bodies are connected to an oil receiving box; an oil guide tank is formed between two adjacent smoke suction holes; the smoke suction holes on the upper layer and the smoke suction holes on the lower layer are staggered at an upper part and a lower part, so that the smoke suction holes on the upper layer are in upper-and-lower correspondence to the oil guide tanks on the lower layer; the oil guide tanks on the upper layer are in upper-and-lower correspondence to the smoke suction holes on the lower layer. Through the oil screens of the structure, the smoke collection volume of the smoke collection groove is increased; the oil smoke storage performance of the oil screens can be improved.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a novel top-suction range hood with an oil net. Background technique [0002] Range hoods, especially top-suction range hoods, are kitchen appliances that purify the kitchen environment. Purify indoor air, and has the function of anti-virus, anti-explosion safety guarantee. [0003] The range hood drives the motor to make the wind wheel rotate at a high speed, so that a negative pressure zone is formed in a certain space above the stove, and the indoor fume gas is sucked into the range hood for purification and removal. However, the range hoods currently on the market The oil screen installed in the center is stretched toward the direction of the stove to form a downward convex cover body, and the downward convex cover body extends below the smoke collection panel. The structural defect is that an upward convex smoke collection chamber will be formed in the smoke collection panel. Th...

[0003] The range hood drives the motor to make the wind wheel rotate at a high speed, so that a negative pressure zone is formed in a certain space above the stove, and the indoor fume gas is sucked into the range hood for purification and removal. However, the range hoods currently on the market The oil screen installed in the center is stretched toward the direction of the stove to form a downward convex cover body, and the downward convex cover body extends below the smoke collection panel. The structural defect is that an upward convex smoke collection chamber will be formed in the smoke collection panel. The downward convex cover will reduce the space of the upward convex smoke collection chamber, so that the oil fume discharge will be blocked by the downward convex cover, which will reduce the practicability of the range hood, and cause a large amount of grease to condense on the outer wall of the downward convex cover, which takes a long time , the grease will solidify or fall to the stove, so that the oil fume is not completely filtered and extracted, which will affect the smoke exhaust performance of the range hood
