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, and is accelerated by the fan, collected by the volute and guided to be discharged outdoors.

In view of the requirement of beauty, the existing range hood has its control panel designed to be hidden, for example, a ceiling-mounted range hood disclosed in chinese patent application No. 202022748211.7, includes: the bottom of a smoke collecting cavity of the smoke collecting hood is provided with a smoke inlet; the control panel is arranged on the smoke collection cover; and the display screen is arranged on at least one of the smoke collecting hood, the smoke collecting plate and the control panel, and the range hood can be a full-hidden range hood embedded into a cabinet for installation.

Since the control panel (switch panel) is hidden in the power-off state, how to wake up the control panel for operation becomes a problem to be solved at present. In addition, the structure of current collection petticoat pipe need be changed in the setting of above-mentioned hidden structure, can lead to holistic structure complicacy, space occupancy is high, cost rising to the structure of increase can lead to the later stage maintenance rate high.

Referring to fig. 1 and 2, a range hood includes a fan frame 1 for installing a fan system (not marked on the drawing, and is a prior art), a fan housing 2 disposed on the periphery of the fan frame 1, and an air intake assembly 3 disposed below the fan frame 1, and may be a range hood in a top-suction type, a side-suction type, or other forms. The fan system, the fan frame 1 and the fan housing 2 jointly form a fan module, and the fan module is of an existing/conventional structure of the range hood.

The range hood further comprises a control screen 4 for controlling the range hood, which is an intelligent screen, such as similar to an intelligent tablet. Control the screen 4 and set up on the fan module, set up with relative fan module liftable, fall to at least part and be located fan module below when needing to use, seek suitable high operation of being convenient for, then rise to the fan module when not needing (especially the front side of fan frame 1), can avoid controlling screen 4 and set up in the runner or the region that the oil smoke passed through from this, and receive the influence of oil smoke. In this embodiment, certain interval has between the front side of fan frame 1 and the front side of fan dustcoat 2, control in screen 4 and its motion can accomodate the space that this interval formed, utilize existing conventional structure of range hood fan module promptly, under the prerequisite that does not increase extra structure and cost, reduces space occupancy, realize controlling hiding of screen 4 to avoid the screen to lead to controlling screen 4 to be stained with by the greasy dirt and life-span to descend under being in the oil smoke environment for a long time when improving operation convenience. When the range hood is opened and enters a use state, the smoke baffle on the front side of the air inlet component 3 is opened so that oil smoke enters the air inlet component 3, and the air inlet form of ring suction or other normally open air inlet forms can be adopted.

The moving mechanism includes a driving mechanism 51 and a lifting fixing plate 52, preferably, the driving mechanism 51 is a linear driving module, and is disposed on the front side of the fan frame 1, and in this embodiment, includes a motor 511, a screw rod 512 and a nut 513, the screw rod 512 extends in the up-and-down direction, the motor 511 can drive the screw rod 512 to rotate around its axis, the nut (not shown) as an output end of the linear driving module is screwed on the screw rod 512, thereby being capable of moving linearly up and down when the screw rod 512 rotates. The driving mechanism 51 may also adopt other existing structures, such as a combination of a motor, a gear and a rack, an electric push rod, and the like.

The elevation fixing plate 52 is fixed to the nut so as to be elevated with the nut. The manipulation screen 4 is fixedly installed on the elevation fixing plate 52 so as to be elevated along with the elevation fixing plate 52. The moving mechanism further comprises guide mechanisms 53 arranged on the left side and the right side of the front side of the fan frame 1, the guide mechanisms 53 are preferably sliding-fit sliding rail assemblies, one sliding rail is fixed with the fan frame 1, and the other sliding rail is fixed with the lifting fixing plate 52. In order to facilitate the fixing of the lifting fixing plate 52 to the left and right slide rails, in this embodiment, the lifting fixing plate 52 has a U-shaped cross section, and the opening of the U-shaped cross section faces backwards.

Referring to fig. 2 and 7, the range hood further includes a mounting plate 6, which is installed below the fan frame 1 and extends forward from a position of the air intake assembly 3 near the upper end, and a sound device (not shown) can be installed on the mounting plate 6 for playing a sound matched with the control screen 4. The front side of the mounting plate 6 extends forwards beyond the front side of the fan frame 1, and the lower end part of the front side of the fan outer cover 2 can be attached to the front side end part of the mounting plate 6. The mounting panel 6 has been seted up near the position of front end portion and has been stepped down hole 61, and the shape and the size of stepping down hole 61 all with control screen 4 adaptation to pass through when can supplying to control screen 4 and go up and down.

Referring to fig. 7, when the range hood is closed or the control screen 4 is not needed, the control screen 4 can be lifted upwards and stored on the mounting plate 6, and at this time, the lower end part of the control screen 4 is preferably located in the receding hole 61 or flush with the upper edge of the receding hole 61 to block the receding hole 61, so as to completely isolate the oil smoke.

Furthermore, the utility model discloses a control screen 4 overall arrangement outside the oil smoke runner, can not exert an influence to the performance of the fan system in the fan frame 1.

The control screen 4 can wake up or control the operation of equipment (a fan system, a smoke baffle plate and the like) through voice interaction, and for this purpose, the range hood further comprises a voice input device for inputting voice for recognition. Referring to fig. 4 to 6, a first sound pickup hole 41 is formed at the bottom of the control screen 4, a second sound pickup hole 42 is formed at the front of the control screen 4, and voice input devices 8 are respectively disposed in positions corresponding to the first sound pickup hole 41 and the second sound pickup hole 42 inside the control screen 4. In the interaction process of the user and the control screen 4, the sound pickup effect is the best when the sound pickup hole of the voice input device is opposite to the mouth of the user, and the recognition degree is high, so that the second sound pickup hole 42 and the corresponding voice input device 8 need to be arranged, and the user's mouth is opposite to the user when the control screen 4 descends. However, when the control screen 4 is lifted up to be hidden in the fan housing 2, the second sound pickup hole 42 is blocked, and the human voice cannot be recognized, and therefore the first sound pickup hole 41 and the corresponding voice input device 8 are provided.
