Description
Technical Field
The utility model relates to a kitchen motor technical field, concretely relates to formula range hood is inhaled to diving with keep off cigarette board.
Background
With the rapid growth of social economy, the requirements of people on the quality of life are higher and higher. As is well known, cooking is closely related to people's lives, and thus, as quality of life is continuously improved, people's demands for kitchen environments are increased. In the cooking process, the generation of a large amount of oil smoke not only harms the health of people, and the oil smoke that gives out also makes the kitchen become dirty, therefore range hood has become the indispensable instrument in the kitchen. Various range hoods appear in the market, and the smoking effect is different, so that a better smoking effect is required, and the type and the structural design of the range hood are very critical.
The common range hood types on the market include a top-suction type range hood, a side-suction type range hood and a submerged type range hood. The ceiling type range hood is generally arranged in a better matching cabinet, the upper surface of a smoke collecting cover of the ceiling type range hood is flatly attached to the bottom surface of the cabinet, so that the mounting position is generally higher, the air inlet of the ceiling type range hood is far away from a cooking bench, the smoking effect is poorer, and in order to improve the smoking effect, the power of a motor needs to be increased, so that the defects of cost rise, noise increase and the like are caused. In addition, the top-suction type smoke exhaust ventilator is higher in installation position and is easy to touch during cooking; the distance between the air inlet and the cooking bench is shortened, the smoking effect is improved, the size of the air cabinet system is larger, but the whole size of the smoke collecting cavity is smaller, so that the air cabinet system is arranged on the upper part or the middle part, and part of the smoke collecting hood is positioned above the plane of the cabinet; in addition, the side-suction range hood forms a certain included angle with the cooking bench, and the smoke collecting effect is poor, so that the smoke escapes. A submerged range hood, which realizes downward movement of a negative pressure region, for example, an automatic lifting range hood with patent number ZL201621063063.2 (with the granted publication number CN206207511U), solves the problem that an air inlet is too far away from a cooking bench by descending the air inlet, but the bottom of a smoke collection cavity is arc-shaped (or inclined plane), when oil smoke rises, the oil smoke can be directly contacted with the bottom of the smoke collection cavity, and the air inlet has the problems of small negative pressure and no smoke baffle plate, so that the oil smoke escape phenomenon is serious, and the smoke suction effect is not ideal; in addition, the distance between the air inlet and the cooking bench is short, and the smoke baffle plate is arranged at the air inlet, so that the pot collision problem can occur, so that the utility model with the patent number of CN201820985116.9 provides a novel structure that the air inlet is arranged below the smoke collecting cavity, the air inlet and the smoke baffle plate are additionally arranged at the upper part of the smoke collecting cavity, but the power of the motor can be increased and the cost is increased due to the use of the two air inlets and the smoke baffle plate; in addition, because the upper part of the cooking bench is also provided with the air inlet, the plane where the upper air inlet of the range hood is positioned occupies more space, the operating space of a cooker is reduced, and the phenomenon of collision is easy to occur.
