L-shaped extractor hood with front cover plate capable of being supported

Abstract

The invention relates to the field of extractor hoods, in particular to an L-shaped extractor hood with a front cover plate capable of being supported. The L-shaped extractor hood comprises a negative pressure source and a body frame. Air inlets only comprise the upper air inlets and the lower air inlet. The lower air inlet is formed in an inward-recessed surface of the L-shaped structure of the body frame and located in the lower portion of the body frame. A top face in the inward-recessed surface faces inwards the body frame and is provided with a backflow groove. The upper air inlets are formed in the backflow groove. The body frame comprises the front cover plate arranged on the lower portion of the body frame in an openable and closeable mode. A downward-extending face in the inward-recessed surface serve as the surface of the front cover plate. The body frame is provided with a protruding and limiting device capable of bouncing. According to the L-shaped extractor hood with the front cover plate capable of being supported, the oil fume extraction effect is better, oil fume overflowing can be better prevented, and the influence on the oil fume extraction effect of a bottom exhaust outlet is lowered; and meanwhile the upper air inlets and the lower air inlet are formed, and the L-shaped extractor hood can be cleaned by users conveniently.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to an L-shaped range hood that can be supported by a front cover. 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.

Problems solved by technology

[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.
