Integrated top smoke blocking and illumination L-shaped range hood

Abstract

The invention relates to the field of range hoods, in particular to an integrated top smoke blocking and illumination L-shaped range hood which comprises a negative pressure source and an inverted L-shaped main body frame, wherein air inlets only comprise an upper air inlet and a lower air inlet; the lower air inlet is formed in the inwards-sunken surface of an L-shaped structure of the main body frame, and is positioned at the lower part of the main body frame; a backflow groove is formed towards the interior of the main body frame in the top surface of the inwards-sunken surface; the upper air inlet is formed in the surface, far away from the downward extending part of the main body frame, in the backflow groove; a light source of a long-strip platy structure is arranged on the outermost side edge of the top surface of the inwards-sunken surface of the main body frame. According to the integrated top smoke blocking and illumination L-shaped range hood, better oil smoke extraction effects are achieved, oil smoke can be better prevented from overflowing, and influence on the oil smoke extraction effects of a bottom exhaust outlet is reduced.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to an L-shaped range hood with top smoke shielding and integrated lighting. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment. [0003] It is installed in the kitchen above the stove. It can quickly take away the waste burned by the stove and the oily fume harmful to the human body produced during the cooking process, and discharge it to the outside, reduce pollution, purify the air, and have the safety guarantee function of anti-virus and explosion-proof. [0004] The traditional type of range hood is mainly hung directly above the stove, but the space it occupies is unreasonable. During use, it is easy to interfere with the chef's head and bump his head. [0005] So later, an L-shaped range hood was slowly derived.

[0004] The traditional type of range hood is mainly hung directly above the stove, but the space it occupies is unreasonable. During use, it is easy to interfere with the chef's head, and it is easy to hit the head

[0005] So later, an L-shaped range hood was slowly derived. There are many technical solutions for setting air inlets in this range hood. Generally, there are air inlets at the bottom, and some are different in the middle of the range hood. There is also an air inlet at the height, and an air inlet at the top, but in the actual use process, it is found that the air inlet at the bottom can actually suck out most of the oil fume, because the oil fume is too large or the air volume of the range hood is insufficient. There will be a small part of the oil fume that will not be exhausted, and then move upwards. For the scheme with air inlets at different heights in the middle, the processing is more difficult, and more openings need to be opened. At the same time, due to the influence of the air inlets at the bottom, it may It will cause air leakage and reduce the effect of the oil fume from the bottom air inlet. In the case of setting the air inlet at the top, if more air inlets are installed at the bottom and middle of the range hood, then it is meaningless to install the air inlet at the top. The smoke that can be smoked is very small, further increasing the cost

[0006] In addition to the air inlet at the bottom, if the air inlet is installed on the top alone, the current situation also has a certain problem of inexhaustible suction at the top air inlet. It overflows into the kitchen along the surface of the range hood, and at the same time, there will be a certain air leakage problem when the air inlet is set on the top, so that a small amount of oil fume drawn from the air inlet at the bottom will leak out, which will also reduce the oil fume from the air inlet at the bottom to a certain extent.
