Abstract
The utility model relates to a telescopic plate for an exhaust fan, which comprises a fan cover, a telescopic plate and a driving device. An exhaust opening is arranged on the fan cover, a plate body of the telescopic plate corresponds to the exhaust opening, a track is arranged, perpendicular to the upright surface direction of the fan cover, on the fan cover, a sliding rod, matching with the track, is correspondingly arranged on the telescopic plate, and the driving device drives the telescopic plate to move forwards and backwards along the direction of the track so as to cover the telescopic plate or open the exhaust opening. When in exhaustion, the telescopic plate is pushed away by the aid of the driving device, and air flow is discharged out of the exhaust opening. When exhaustion is not needed, the driving device resets the telescopic plate so that the exhaust opening is covered by the telescopic plate to prevent outdoor insects and sundries from entering a room from the exhaust opening. The telescopic plate for an exhaust fan is reasonable in structure and convenient in control, does not affect the work efficiency of the exhaust fan in use, is novel in designed appearance, and improves the grade of a range hood.
Description
Technical field
The utility model relates to a kind of air interchanger, particularly a kind of flexible dish that is used for air exhauster.
Background technology
Air-extractor exhaust blower commonly used, smoke exhaust ventilator etc., all be to utilize ventilating fan that indoor unclean gas is taken away in use, but because the exhaust outlet communication chamber is inside and outside, smoke exhaust ventilator is not when working, materials such as outdoor insect, airborne floating thing, rainwater by in the exhaust outlet inlet chamber, are had the family to bring puzzlement easily.Though being arranged, the part smoke exhaust ventilator shutter has been installed in the outside, when air exhauster is worked, utilize wind-force that shutter is pushed open, when air exhauster stops, utilize self gravitation to reset and close, close exhaust outlet, but the design of this shutter need utilize wind-force to promote just can open, reduced the efficient of air exhauster, in addition, the as easy as rolling off a log phase opening and closing function that influences when shutter has greasy dirt is safeguarded also inconvenient.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, control is convenient, high, the both artistic and practical flexible dish that is used for air exhauster of reliability.
The technical scheme that the utility model adopted is:
The flexible dish that is used for air exhauster, comprise hood, flexible dish and drive unit, hood is provided with ventilating opening, the disk body of flexible dish is corresponding to ventilating opening, hood is provided with track on perpendicular to its facade direction, the corresponding slide bar that matches with track that is provided with of flexible dish, it is forward and backward mobile that drive unit drives flexible rim orbital direction, makes flexible disk cover live or open ventilating opening.
Further improvement of the utility model, drive unit comprise support and rack-mount motor, and support is fixedlyed connected with hood, and the end of machine shaft is equipped with gear, and flexible dish is provided with the straight-tooth piece that cooperates with gear.
Further improvement of the utility model is provided with the stopping means that retrains the forward and backward displacement of this straight-tooth piece between described support and the straight-tooth piece.
Further improvement of the utility model, described track, support and motor all are installed on the back of hood.
The beneficial effects of the utility model are: when bleeding, utilize drive unit will stretch the dish push open, air-flow is discharged outside ventilating opening; When not needing to bleed, drive unit will stretch to coil and reset, flexible dish is covered in ventilating opening, prevent outdoor insect foreign material in the ventilating opening inlet chamber, product structure is reasonable, and control is convenient, can not influence the operating efficiency of air exhauster in use, in addition, design model novelty of this flexible dish has improved the class of smoke exhaust ventilator.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of flexible dish when not working;
The structural representation that flexible dish stretched out when Fig. 2 was work;
Fig. 3 is another angle structural representation of Fig. 1;
Fig. 4 is another angle structural representation of Fig. 2.
The specific embodiment
Referring to figs. 1 through shown in Figure 4, the flexible dish that is used for air exhauster, comprise hood 1, flexible dish 2 and drive unit, hood 1 is provided with ventilating opening 11, the disk body 21 of flexible dish 2 is corresponding to ventilating opening 11, and hood 1 is provided with track 12 on perpendicular to its facade direction, the flexible dish 2 corresponding slide bars 22 that match with track 12 that are provided with, drive unit drives flexible dish 2 and moves along track 12 directions are forward and backward, makes flexible dish 2 cover or open ventilating opening 11.
The utility model both can be applicable to exhaust system, also can be applicable on the smoke exhaust ventilator, work with smoke exhaust ventilator is example: when smoke exhaust ventilator is worked, its air exhauster need be evacuated to indoor oil smoke outdoor, after air exhauster is opened, the motor 32 of drive unit also starts, the gear 33 that is installed on the motor shaft rotates, promotion straight-tooth piece 23 and flexible dish 2 move, because the slide bar 22 on the flexible dish 2 also is subjected to the constraint of track 12, the direction of flexible rim track 12 moves forward, and the disk body 21 of flexible dish 2 leaves ventilating opening 11, makes indoor oil smoke walk around disk body 21 backs and discharges outdoor from ventilating opening 11; When air exhauster cut out, the flexible dish of motor-driven resetted, and the disk body 21 of flexible dish 2 is covered in ventilating opening 11.
In order to make control more reasonable, be provided with the stopping means 4 of these straight-tooth piece 23 forward and backward displacements of constraint between support 31 and the straight-tooth piece 23, this stopping means can be to be installed on the block of support two in order to the forward and backward displacement of constraint straight-tooth piece, also can be travel switch.
In addition, the design's track 12, support 31 and motor 32 all are installed on the back of hood 1, and corresponding, slide bar 22, straight-tooth piece 23 also are located at the back, have guaranteed the handsome in appearance of smoke exhaust ventilator front side.
The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.
