Description

Fume exhaust fan

Technical Field

The utility model relates to an oil smoke purifier, especially a range hood.

Background

The range hood has become one of the indispensable kitchen household electrical appliances in modern families. The range hood works by utilizing the fluid dynamics principle, sucks and exhausts oil smoke through a centrifugal fan arranged in the range hood, and filters partial grease particles by using a filter screen. The centrifugal fan comprises a volute, an impeller arranged in the volute and a motor driving the impeller to rotate. When the impeller rotates, negative pressure suction is generated in the center of the fan, oil smoke below the range hood is sucked into the fan, accelerated by the fan and then collected and guided by the volute to be discharged out of a room.

The actual operation environment of range hood on the existing market all uses comparatively traditional control mode, and screen and range hood can't fuse, and the position and the angle of screen depend on range hood's panel, lead to too high inconvenient operation of slope or too, can't satisfy actual control operation's demand. In addition, the existing screen is exposed in an oil smoke environment no matter in a working state or a non-working state, the screen is polluted by oil smoke for a long time, so that the surface of the screen is greasy, and display or touch is influenced, and the oil smoke is usually higher in temperature, so that the service life of the screen is influenced when the screen is in a high-temperature environment for a long time; even some prior art have also adopted some hidden schemes to prevent that the screen from revealing under the oil smoke environment, for example, set up solitary protective housing or whole elevating gear for the screen additional and set up special protective housing, however, above-mentioned setting can lead to holistic structure complicacy, space occupancy is high, the cost rises to the structure of increase can lead to the later stage maintenance rate height.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a not enough exists to the above-mentioned prior art provides a range hood, makes the screen keep away from the oil smoke region under non-operating condition when it can improve screen operation convenience, avoids the screen to be infected with by the greasy dirt, influences the life-span.

The utility model provides a technical scheme that above-mentioned first technical problem adopted does: the utility model provides a range hood, includes fan module and the control screen of setting in the fan module, its characterized in that: the control screen can be lifted relative to the fan module, so that the control screen can be at least partially lowered below the fan module. The control screen is arranged relative to the fan module instead of the panel and the like, so that the control screen is in a state of being far away from an oil smoke area when not in use, and the problem of being polluted by oil stains is avoided; when the screen is required to be controlled, the screen is lowered to the position below the fan module through the lifting device, so that the screen can be ensured to be positioned in the front or on the upper side of a user, and the control of the user is facilitated.

Furthermore, because the range hood can not completely realize the suction of the oil smoke, part of escaping oil smoke is inevitably generated, the part of escaping oil smoke can rise to the area of the fan module, the control screen can still inevitably contact the oil smoke, and the risk of oil stain contamination and service life reduction of the control screen can be inevitably generated after long-term contact. Therefore, the second technical problem to be solved by the present invention is how to solve the above problems in a manner of low cost, low space occupation, and simple structure design.
