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 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.

Preferably, the display device is one of a mobile phone, a tablet computer and a smart screen.

According to the utility model discloses an aspect, be provided with magnet on the fixed carrier for display device is fixed with the fixed carrier through magnetism mode of inhaling.

According to the utility model discloses a another aspect, can dismantle on the fixed carrier and be connected with external fixed bolster, display device presss from both sides tightly on external fixed bolster. Therefore, even if the display device without the magnetic attraction function is connected with the fixed carrier conveniently.

The utility model provides a technical scheme that above-mentioned second technical problem adopted is: the range hood further comprises a fan module, and the control screen is arranged on the fan module and can lift relative to the fan module, so that at least part of the control screen can descend below the fan module. Because the control screen is arranged relative to the fan module instead of the panel and the like, the control screen is in a state of being far away from an oil smoke area when not used, thereby avoiding the problem of being polluted by oil stains; 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 fan module comprises a fan frame for arranging the fan system and a fan outer cover arranged on the periphery of the fan frame, and the control screen can be contained in a space between the front sides of the fan frame and the fan outer cover. Through will controlling the screen pertinence and set up in the space between fan frame and fan guard, the purpose utilizes the existing/conventional structure of range hood's fan module, do not increase additional structure and cost, under the prerequisite of reduction space occupancy, realize controlling hiding of screen, avoid exposing under high temperature oil smoke environment for a long time under the off-working condition, thereby further realized more effectively isolated with oil smoke environment or kitchen high temperature environment, the probability of controlling the screen and being infected with by the greasy dirt has been reduced, high temperature direct contact has been avoided, and the service life is prolonged.

In order to facilitate the lifting of the control screen, the range hood further comprises a moving mechanism for driving the control screen to lift, the moving mechanism comprises a driving mechanism and a lifting fixing plate, the driving mechanism is a linear driving module, the lifting fixing plate is fixed with the output end of the linear driving module, and the fixed carrier is fixed with the lifting fixing plate.

Control the storage space of screen for the convenience of sealing, be convenient for simultaneously install functional module such as stereo set, camera, range hood is still including setting up the mounting panel in fan housing bottom, the front side of mounting panel extends the front side that exceeds the fan frame forward, the hole of stepping down that passes through when the screen goes up and down is offered to the position that the mounting panel is close to the front side tip.

Compared with the prior art, the utility model has the advantages of: by arranging the replaceable display equipment, the display equipment of the range hood can be replaced when the display equipment cannot meet the requirement, so that the convenience in cooking is improved, for example, the menu is convenient to look up, and a control mode which is more in line with the operation habit is provided; the liftable control screen is arranged relative to the fan module, so that the operation requirements of different heights can be met, and the operation convenience is improved; the control screen is arranged in the space between the fan frame and the fan cover in a targeted manner, and the control screen is hidden under the premise of not increasing additional structures and cost and reducing the space occupancy rate by utilizing the existing/conventional structure of the fan module of the range hood, so that the operation convenience is improved, and the screen is prevented from being polluted by oil stains and the service life is shortened when the screen is in an oil smoke environment for a long time.
