Abstract
The utility model discloses a range hood which comprises a machine body, a centrifugal fan arranged in the machine body, a housing and a smoke absorption opening formed in the housing, wherein a movable louver comprising a plurality of parallel blades is arranged on the smoke absorption opening and comprises an opening position and a closing position; and an included angle formed between the plane in which the rotating shafts of the plurality of blades are arranged and a horizontal plane is less than or equal to 90 degrees. The movable louver is arranged on the smoke absorption opening; when the range hood works, the smoke absorption opening is opened; when the range hood does not work, the smoke absorption opening is closed; and therefore, backward flow of lampblack and escape of smoke can be effectively prevented.
Description
Technical field
The utility model relates to a kind of kitchen appliance, particularly relates to a kind of smoke exhaust ventilator, and it comprises body, casing, centrifugal blower and is arranged on smoking port on the casing.
Background technology
Conventional smoke exhaust ventilator, the oil smoke entrance is open, the cigarette machine is when off working state, even filled check (non-return) valve in the flue, neighbour's's oil smoke still can waft into oneself kitchen.In addition, the peculiar smell of lampblack absorber the inside itself also can blow out.Notification number is that the Chinese utility model patent of CN2050298U discloses a kind of smoke exhaust ventilator with the automatic valve device, it is that the automatic valve device is housed in the exhaust passage of smoke exhaust ventilator, this valving is opened when the smoke exhaust ventilator exhaust automatically, Exhaust Gas, auto-closing when stopping exhaust, close the exhaust passage, thereby solved existing smoke exhaust ventilator since dust during the always unimpeded not exhaust that produces of exhaust passage, winter cold air pour in down a chimney problem, and smoke exhaust ventilator is used for kitchen, the taint of odour problem when a lot of users share a flue.Although this utility model has stoped the backflow of partial fume by an automatic valve, because this automatic valve is arranged on the rear portion, roughly the same with existing non-return valve effect.And the smoking port of lampblack absorber is still open, still has smoke to overflow after lampblack absorber uses.
The utility model content
The technical problems to be solved in the utility model provides a kind of smoke exhaust ventilator, and it opens this smoking port by improving the structure of smoke exhaust ventilator smoking port when smoke exhaust ventilator is worked, and closes when not working, thereby prevents that effectively pouring in down a chimney with smoke of oil smoke from overflowing.
Technical solutions of the utility model are: a kind of smoke exhaust ventilator comprises body, is arranged on centrifugal blower, the casing in the body and is arranged on smoking port on the casing; Be provided with the movable louver that comprises some parallel hinges at smoking port; Described movable louver comprises an open position and a closing position; The plane at the rotating shaft place of described some hinges and the angle of horizontal plane are less than or equal to 90 degree.By a movable louver is set at smoking port, this smoking port when working, is opened by smoke exhaust ventilator, and when not working, close, thereby prevent that effectively pouring in down a chimney with smoke of oil smoke from overflowing.
As a kind of optimal technical scheme, the hinge of described movable louver is and is horizontally disposed with.The negative pressure that makes this activity louver utilize the centrifugal blower in the body to form is opened louver; More can when shutdown, utilize the weight of hinge self to close.
For the ease of movable louver is control effectively at open position and closing position, described movable louver comprises the controlling organization of control activity louver folding; Described controlling organization comprises the drag-line with some hinge interlocks.The folding of the pulling control activity louver by drag-line, simple in structure, easy to use.
As a kind of optimal technical scheme, described controlling organization comprises that also one drives the drive motors of described drag-line action and the commutating circuit of control drive motors commutation.Make this activity louver by the commutation of the running of the switch gearing control motor of smoke exhaust ventilator, the folding of realization activity louver and the duty of smoke exhaust ventilator are synchronous.
In order to reduce the driving force that louver opens and to make lampblack absorber more attractive in appearance, described movable louver is when open mode, and described hinge turns to the inside of casing.
Adopt the technical solution of the utility model, the one, prevent that effectively pouring in down a chimney with smoke of oil smoke from overflowing; The 2nd, increase shutter structure and make smoking port more attractive in appearance.

The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Referring to Fig. 1, a kind of smoke exhaust ventilator, comprise body 1, be arranged on centrifugal blower 3 in the body 1, be arranged on body 1 lower end casing 2, be arranged on illuminating lamp 7, oil collection box 5 and control button 6 on the casing 2.
Referring to Fig. 2～Fig. 4, be provided with a smoking port 201 at casing 2, smoke exhaust ventilator is in when work, and smog is sucked from this smoking port 201 by the suction of centrifugal blower 3, and the flue from the body 1 is discharged again.Be provided with the edge strip 202 of inside turnover in smoking port 201 both lateral sides, be equipped with five axis holes at each edge strip 202, the axis hole on the both sides edge strip 202 is corresponding in twos.On this smoking port 201, laterally be provided with a movable louver 4 that comprises five hinges 401.Every hinge 401 an all sad hinge rotating shaft 402 is articulated in the axis hole on the edge strip 202.
Be provided with a controlling organization at movable louver 4.This controlling organization comprises a drag-line 405, a gangbar 406 at least.But also comprise in the present embodiment a drive motors 403 and commutating circuit (not showing on the figure).Wherein, gangbar 406 is arranged on a side of movable louver 4, and it links to each other with each hinge 401 by universal driving shaft 407.Upper end in gangbar 406 connects drag-line 405.When not having the embodiment of drive motors 403, movable louver 4 is by gangbar 406 direct pulls of drag-line 405, the switching of realization activity louver 4 between open position and closing position.And when the embodiment of the commutating circuit with drive motors 403, drag-line 405 is connected on the driving wheel 404 that is fixed on drive motors 403 output shafts again, controls the positive and negative of drive motors 403 then the switching of realization activity louver 4 between open position and closing position by the control button 6 on the casing 2 and commutating circuit.
Above-described embodiment is a kind of preferred version of the present utility model, is not the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that is no more than the technical scheme that claim puts down in writing.
