Linkage open and close double range hood

Abstract

A linkage opening and closing double range hood, comprising a range hood at least composed of a panel, a bracket and an outer shell, the range hood is provided with a fan assembly and an electric control box, the panel is provided with a smoking port corresponding to the fan assembly, and on the smoking port At least a flip-type opening and closing deflector and a main cover are provided; a linkage device driven by a motor is arranged between the deflector and the main cover, and the intermodal device drives the main cover while controlling the outward tilt of the deflector. The cover plate sinks inwards to open the smoking port. The present invention is provided with flip-type opening and closing guide plate and main cover plate on the smoking port, which can effectively prevent oil fume from pouring back and cover the smoking port, improve the effect of oil smoke extraction and appearance cleanliness of the range hood, and at the same time, the guide plate and main The cover plate is simultaneously driven by a motor and a linkage device, which simplifies the manufacturing process and assembly process of the product, and reduces the production and use costs; and the range hood is also equipped with an internal automatic cleaning device, an anti-pinch sensor device and double-sided control The control panel is very practical.

Description

technical field [0001] The invention relates to a range hood, in particular to a linkage opening and closing double range hood. Background technique [0002] With the progress of human civilization, in the field of daily-use stoves and range hoods, the shielding, separation and discharge of oil fumes are becoming more and more difficult due to the improvement of the airtightness of modern living rooms and people's requirements for living environments. Among them, the deflector of the range hood is generally fixed on the panel, which not only takes up space in the kitchen, but also the smoking port is always open, which not only affects the appearance of the range hood, especially the range hood that has been used for a long time and has not been cleaned is even more serious. ; In modern urban housing, most of the public exhaust pipes are used, which is easy to cause oil fumes to flow backwards and pollute the indoor air. For example, Chinese Patent No. 20101096655.2 also pr...

Problems solved by technology

However, due to structural limitations, when the deflector is pushed forward as a whole, the thickness of the body will be increased, and the user is easily injured by the pushed out deflector during use. It can enter from around the deflector, and the oil fume on the front of the deflector is blocked by the deflector, which makes it easy to escape upward along the outer surface of the deflector, or hang on the deflector, resulting in dripping Oil or oil leakage phenomenon, resulting in poor smoke absorption effect of the range hood, and affecting the appearance
