Problems solved by technology

Its advantage is that, using the principle of eddy current wind pressure, most of the oil fumes that are relatively close to the stove are sucked in the form of an arc, which can reduce the adverse effects on human health, and the power source (fan) is closer to the stove. Basically, it will not reduce the suction effect of the power source (fan); the disadvantage is that the power source (fan) generally cannot be aimed at the stove, which will also cause the oily fume to be completely inhaled. , "Stew" and other cooking methods may even cause smoke oil to rise and overflow

[0031] see Figure 1-Figure 10 , the range hood includes a hood main body 10 provided with a smoking port and a smoke exhaust port (no label in the figure), the inside of the hood main body 10 is provided with a first wind cabinet 20 for smoking on the side of the smoking port, and The inner top is provided with a second wind cabinet 30 for smoking at the top of the smoking port.

[0032] The exhaust ends of the first wind cabinet 20 and the second wind cabinet 30 communicate with the smoke exhaust port through the one-way smoke exhaust channel respectively.

[0033] The first wind cabinet 20 is composed of at least one group of fans, and each group of fans corresponds to a group of independent exhaust ends; the second wind cabinet 30 is composed of at least one group of fans, and each group of fans corresponds to a group of independent exhaust ends. In this embodiment, the first air cabinet 20 is composed of a group of fans, with a group of independent exhaust ends, such as ...

[0037] see Figure 11-Figure 13 , the main difference between this range hood and the first embodiment is that the first wind cabinet 20 is composed of two groups of fans, and has two groups of independent exhaust ends, and the two groups of exhaust ends are respectively connected to the rear of the air guide cover 40 The two groups of one-way exhaust passages on the side are connected. Similarly, if one group of fans of the first wind cabinet 20 is turned on separately, it will not interfere with each other's exhaust ends, and will not cause turbulence to reduce the smoking effect, let alone Air flow backflow will be formed. The range hood forms a three-dimensional or rectangular three-dimensional smoking on the cooktop through the combination of top suction and side suction, which greatly improves the smoking effect, prevents the fume from escaping to the greatest extent, and solves the existing problems of this product on the market today. insufficient.

Abstract

A range hood comprises a range hood main body, wherein the range hood main body is provided with lampblack sucking openings and lampblack discharging openings; a first air cabinet which is used for sucking lampblack from the side parts of the lampblack sucking openings is arranged on the inner side of the range hood main body; a second air cabinet which is used for sucking lampblack from the tops of the lampblack sucking openings is arranged on the inner top of the range hood main body; an exhaust end of the first air cabinet and an exhaust end of the second air cabinet are respectively communicated with the lampblack discharging openings through one-way lampblack discharging channels; the first air cabinet consists of at least one group of fans; the second air cabinet consists of at least one group of fans; each group of fans correspond to a group of independent exhaust ends; at least one group of one-way exhaust channels are formed at positions, which correspond to each group of exhaust ends, of the lampblack discharging openings; the one-way exhaust channels are separated by separating pieces arranged on the lampblack discharging openings; and one-way valve plates are respectively connected with the separating pieces correspond to the groups of one-way exhaust channels. A three-dimensional lampblack sucking mode is realized for a cooking bench by combining top suction and side suction, a lampblack sucking effect is greatly improved, lampblack is prevented from escaping to the maximum degree, and shortcomings of the conventional range hoods in the markets are overcome.

Description

technical field [0001] The invention relates to a range hood. Background technique [0002] Range hoods on the market today are generally divided into two forms. [0003] The first is top suction. For example, Chinese Patent Document No. CN201615526U disclosed a range hood on October 27, 2010. The range hood includes a housing, and the front end of the housing is provided with a panel inclined forward. The panel The upper end is connected with a wind deflector through a hinge joint, and a support frame is provided on the panel corresponding to the lower end of the wind deflector, and a side air inlet gap is formed between the panel and the wind deflector. The upper end of the housing is provided with an outlet Air duct, the air outlet duct is provided with a wind wheel and a motor, an oil guide groove is provided in the housing, an oil guide pipe is provided at the lower end of the oil guide groove, and an oil collector is provided at the lower end of the outer housing. A...
