Description

Oil guide structure of range hood

Technical Field

The utility model relates to a range hood, in particular to an oil guide structure of a range hood.

Background

When the range hood is used, the oil guide structure directly influences the treatment condition of oil stains on the range hood, and the problems that whether the oil stains can not drip on a cooking bench, whether the oil guide structure of the range hood can effectively and smoothly guide the oil, whether the oil stains on the splicing seams of the range hood can be prevented from leaking, whether the oil stains are convenient to disassemble and clean and the like are all considered are solved. The oil guide plate air inlet of the existing range hood is positioned in the middle of the fume collecting cover panel, oil stains can be accumulated on a top plate above the oil guide plate air inlet, the accumulated oil stains can penetrate through the oil guide plate air inlet and drip onto a cooking bench, or the accumulated oil stains drip down along the lower surface of the fume collecting cover panel after overflowing and drip onto the cooking bench, and therefore the existing range hood is not beneficial to cleaning of users. In addition, due to reasons such as installation errors, the bottom of the range hood inclines to a certain degree, oil stains can be accumulated to one side, oil is more hidden in the range hood, and cleaning of a user is affected.

In order to smoothly guide oil stains into the oil cup, various oil guide structures of a range hood are disclosed in the prior art, for example, an oil guide structure of a side-draft range hood disclosed in chinese patent No. ZL 201210468503.2 (publication No. CN 102980229B), the oil guide structure of the side-draft range hood includes a panel and an oil guide plate, the panel is obliquely disposed between left and right side plates of a housing, the panel is disposed in front of the oil guide plate and spaced apart from the oil guide plate, an oil guide plate air inlet is formed in the middle of the panel, an oil guide plate air inlet is formed in the middle of the oil guide plate, a blocking structure is disposed above the oil guide plate and is tilted upward and forward, and the blocking structure can block a top plate in the housing, which is just above the oil guide plate air inlet. Lead the greasy dirt directly over the oiled-plate air intake can gather on blocking the structure, and because blocking the structure and having certain angle, so oil drips can not fall perpendicularly, but in proper order along blocking the structure and leading the oiled-plate down to the oil cup, and the regional oil of the casing roof front side that can't be covered by blocking the structure drips earlier on the top panel when dripping, then flow into the oil cup through filter screen and lower panel, can lead to being stained with the greasy dirt on the filter screen like this, not only the filter screen is clean inconvenient, and the oil of filter screen also can directly drip on the top of a kitchen range.
