Description

Lifting type range hood

Technical Field

The utility model relates to a range hood, in particular to a lifting type range hood.

Background

Chinese cooking can generate a large amount of oil smoke, so that the kitchen environment is clean and the health of a human body is kept, the range hood becomes one of the indispensable equipment of a modern family kitchen, however, along with the higher and higher application rate of the range hood, people pay more attention to the oil smoke absorbing effect of the range hood. If the interval of the air inlet of the range hood and the oil smoke generation area is larger, the suction path of the oil smoke is longer, the suction time is increased, so that the oil smoke escape phenomenon is easy to generate in the cooking process, if the installation height of the range hood is reduced, the smoke inlet is as close to a smoke source as possible, the negative pressure is expanded downwards, although the range hood is favorable for improving the oil smoke suction effect, the cooking space is too small, the head of a cooking person carelessly and easily touches the smoke collecting hood, and the whole appearance of the sight and the kitchen is also influenced after the installation height is reduced. Therefore, the ultra-thin shape of the whole machine is adopted at present, and then the smoke inlet is arranged below and is lifted independently. For the ultra-thin shape, the effective area of the connecting interface part is limited, so that the cost for improving the performance is increased, and the oil smoke absorbing effect is correspondingly reduced; for the form that the smoke inlet is lifted independently, the front side of the smoke inlet is not similar to a smoke baffle plate structure, so that the negative pressure area is smaller, and the problem of poor smoke exhaust effect can be caused.
