Description
Technical Field
The utility model belongs to the technical field of the lampblack absorber, specifically a lampblack absorber.
Background
The range hood is a common electrical appliance in a kitchen and is used for absorbing oil smoke generated by cooking in the kitchen and preventing indoor environment from being polluted. The centrifugal fan of the existing range hood is generally arranged at the innermost side of the shell of the range hood, when the smoke baffle is turned over at a large angle, the suction force of the centrifugal fan to the outer end of the smoke baffle can be remarkably reduced, and the centrifugal fan with enough high power is required to be equipped to ensure the suction force of the outer end of the smoke baffle when the smoke baffle is turned over at a large angle. Therefore, a centrifugal fan with larger power is required to be equipped, and when the oil smoke is not large, the centrifugal fan with larger power is not necessary, and only the consumed electric energy is increased.
Disclosure of Invention
The utility model discloses it is not enough to prior art, provide a lampblack absorber, the centrifugal fan of this kind of lampblack absorber can remove to the direction that is close to the inlet scoop along with keeping off the expansion of cigarette board to can guarantee with less centrifugal fan power to keep off the cigarette board and turn over the suction that keeps off cigarette board outer end department when the angle is great, reach the purpose of the energy can be saved.
In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the utility model provides a range hood, includes the lampblack absorber casing, be provided with centrifugal fan in the casing, centrifugal fan's air outlet is connected with the air-out passageway, the casing front end has the inlet scoop, it is provided with the cigarette board to rotate on the inlet scoop, the casing both sides are equipped with two at least transverse slide, at least one be equipped with a plurality of spacing grooves on the transverse slide, the centrifugal fan both sides are provided with two at least and are in gliding slide bar in the transverse slide, be equipped with the spring on the slide bar, the spring is right the elasticity orientation of slide bar the spacing groove, on the cigarette board with be provided with the connecting rod between on the centrifugal fan, the connecting rod both ends respectively with the cigarette board with the centrifugal fan is articulated, centrifugal fan's air outlet with the air-out passageway passes through flexible pipeline and connects. The sliding rod of the range hood can be clamped into the limiting groove for limiting in the process of opening the smoke baffle plate, so that the range hood can limit the centrifugal fan and limit the smoke baffle plate, and the multi-angle positioning of the smoke baffle plate is realized; along with the range increase centrifugal fan that keeps off the cigarette board and open also is close to the inlet scoop more, centrifugal fan can guarantee with less power that keep off the suction of cigarette board outer end department when the cigarette board turns over the angle great, reaches the purpose of the energy can be saved.
Among the above-mentioned technical scheme, it is concrete, lampblack absorber casing both sides all are equipped with two horizontal slide of parallel, the centrifugal fan both sides are provided with a vertical slide respectively, it is provided with two sliders, two to slide on the vertical slide all be provided with on the slider the slide bar, two be provided with between the slider the spring, it is a plurality of the spacing groove is located upside horizontal slide's upside and/or is located downside horizontal slide.
Among the above-mentioned technical scheme, preferred, the upside the transverse slipway end connection has the arc slide, the upside of arc slide outer end is provided with the spacing groove. When the centrifugal fan slides to the end part of the transverse slideway of the lower side, the centrifugal fan can rotate one end distance along the arc-shaped slideway, so that the air inlet of the centrifugal fan can be closer to the air suction opening.
Compared with the prior art, the utility model, following beneficial effect has: the sliding rod of the range hood can be clamped into the limiting groove for limiting in the process of opening the smoke baffle plate, so that the range hood can limit the centrifugal fan and limit the smoke baffle plate, and the multi-angle positioning of the smoke baffle plate is realized; along with the range increase centrifugal fan that keeps off the cigarette board and open also is close to the inlet scoop more, centrifugal fan can guarantee with less power that keep off the suction of cigarette board outer end department when the cigarette board turns over the angle great, reaches the purpose of the energy can be saved.
Drawings
Fig. 1 is a schematic structural view of the smoke barrier of the embodiment of the present invention when it is unfolded at a certain angle.
Fig. 2 is a schematic structural view of the smoke barrier of the embodiment of the present invention when it is expanded to the maximum angle.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 2, a range hood comprises a range hood shell 1, a centrifugal fan 2 is arranged in the shell 1, an air outlet of the centrifugal fan 2 is connected with an air outlet channel 3 through a flexible pipeline 11, an air suction opening 4 is arranged at the front end of the shell 1, the air suction opening 4 is connected with a smoke baffle plate 5 with the upper end hinged, two parallel transverse slideways 6 with one higher end and one lower end are arranged at two sides of the shell 1, a vertical slideway 12 is respectively arranged at two sides of the centrifugal fan 2, two sliding blocks 13 are arranged on the vertical slideway 12 in a sliding manner, sliding rods 8 are arranged on the two sliding blocks 13, a spring 9 is arranged between the two sliding blocks 13, the sliding rods 8 slide in the transverse slideways 6, a plurality of uniformly distributed limiting grooves 7 are arranged at the upper side of the upper transverse slideway 6 and the lower side of the lower transverse slideway 6, an arc slideway 14 is connected at the end of the, the slide bar 8 is pushed open towards both sides by spring 9, at the gliding in-process of slide bar 8 in transverse slipway 6, slide bar 8 can be embedded into spacing groove 7, can fix a position centrifugal fan 2, be provided with connecting rod 10 on the cigarette board 5 and on the centrifugal fan 2 between, connecting rod 10 both ends are articulated with cigarette board 5 and centrifugal fan 2 respectively, can drive centrifugal fan 2 and remove when the cigarette board 5 rotates is kept off in the pulling, and come spacing centrifugal fan 2 and keep off cigarette board 5 through spacing groove 7.
