Description
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 operating environment of the range hood in the current market uses a traditional control mode, and a screen and the range hood cannot be fused. For example, the intelligent screen range hood disclosed in the Chinese patent with the application number of 201911286720.8. The intelligent screen range hood comprises a range hood body, an intelligent screen arranged on the range hood body, a controller, a communication module and an audio output module.
Because the intelligent screen is fixedly arranged, a user can only use the screen of the range hood per se, and the movement replaceability is poor or basically none; the position and the angle of the screen depend on the panel of the range hood, so that the screen is too inclined or too high to be operated conveniently, and the requirement of actual control operation cannot be met; in addition, the 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, the surface of the screen is greasy, and display or touch is affected, and the oil smoke is usually high in temperature, so that the service life of the screen is affected 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 is extra sets up special protective housing, however, above-mentioned setting can lead to holistic structure complicacy, space occupancy height, cost rising 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 first technical problem that to the not enough of above-mentioned prior art existence, provide a range hood, can conveniently change the display device who controls to convenience when improving the culinary art.
The utility model discloses the second technical problem that will solve is not enough to above-mentioned prior art existence, 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, is including controlling the screen, its characterized in that: the control screen comprises a fixed carrier and replaceable display equipment, and the display equipment is detachably connected with the fixed carrier.
Through setting up interchangeable display device, can change when the display device of range hood from the area can't satisfy the demand to convenience when improving the culinary art, if be convenient for look up the menu, provide the control mode etc. that more accord with the operation custom.
