Summary of the invention
The utility model provides the smoke exhaust ventilator of the automatic folding of a kind of air inlet at the problems referred to above that prior art exists, and when smoke exhaust ventilator does not use air inlet is closed, and prevents that effectively greasy dirt is dropped on the kitchen range top.
The technical scheme that the utility model adopted is:
The smoke exhaust ventilator of the automatic folding of air inlet, comprise casing and the air intake oil net affixed with casing, the air inlet of described casing exceeds air intake oil network plane, and casing is slidingly fitted with and can opens, the wind deflector of closed air inlet, and described wind deflector has electric driver and position-limit mechanism.
Described wind deflector electric driver comprises successively power supply, start stop switch and the stepper motor that is electrically connected, and stepper motor is connected with motor output shaft rotatablely moved and is converted into the transmission mechanism that wind deflector laterally slides.
Described transmission mechanism comprise the gear that is fixedly set on the stepper motor output shaft and with the tooth bar of meshed transmission gear, the tooth bar two ends are provided with position-limit mechanism, described stepper motor and box inside wall are affixed, and tooth bar and wind deflector medial surface are affixed, and start stop switch is positioned at the wind deflector lateral surface.
The position-limit mechanism at described tooth bar two ends is a travel switch, and described travel switch is electrically connected with the start stop switch of stepper motor.
Casing frame and wind deflector are slidingly installed by chute and slide rail cooperation.
Described wind deflector comprises symmetrically arranged two, and its electric driver mechanism also is symmetrical arranged.
Described air intake oil net is the plane network structure, and mesh is rounded square or oval.。
The beneficial effects of the utility model are: the wind deflector of folding automatically is set at the air inlet place, closes air inlet when not using, effectively prevent the greasy dirt drippage, improve the kitchen outward appearance greatly; The wind deflector driving mechanism structure is simple, reliable operation; It is netted, easy to process that air intake oil net is the plane, and air-out area is big, prevents that effectively mesh from stopping up.

Fig. 1 is a forward structure schematic diagram of the present utility model;
Fig. 2 is a side direction structural scheme of mechanism of the present utility model;
Fig. 3 is that the A-A of Fig. 1 is to cutaway view;
Fig. 4 is that the B-B of Fig. 2 is to cutaway view.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
See figures.1.and.2, the smoke exhaust ventilator of the automatic folding of air inlet, comprise casing 1 and the air intake oil net 2 affixed with casing 1, the air inlet of casing 1 exceeds air intake oil network plane, air intake oil net 2 is the plane network structure, mesh can be made multiple shape, for example circular, square, rectangle or oval or the like.Casing 1 is slidingly fitted with and can opens, the wind deflector 3 of closed air inlet, casing 1 and wind deflector 3 the mode of being slidingly installed can have multiple, can be that one-body molded slide rail and the chute of being provided with of casing and wind deflector cooperates, also can add the leading block of side direction relative limit, in the present embodiment, the two cooperation by slide rail and chute is slidingly installed, concrete structure is with reference to shown in Figure 4, the casing 1 frame middle part of twice side up and down has chute, the wind deflector back side has two one slide rails that cooperate with the casing chute, can certainly be that slide rail is set on the casing, chute is set on the wind deflector, the position also can be selected as required, if guarantee wind deflector 3 relatively casing 1 opens slidably and closure.
With reference to shown in Figure 3, in order to guarantee that air inlet is automatically opened and closure, wind deflector 3 has electric driver and position-limit mechanism.The wind deflector electric driver comprises successively power supply (not shown), start stop switch 4 and the stepper motor 5 that is electrically connected, and stepper motor 5 is connected with motor output shaft rotatablely moved and is converted into the transmission mechanism that wind deflector laterally slides.In the present embodiment, transmission mechanism comprise the gear 6 that is fixedly set on the stepper motor output shaft and with the tooth bar 7 of meshed transmission gear, for cutting down finished cost, gear and tooth bar adopt plastic material, tooth bar 7 two ends are provided with position-limit mechanism, and stepper motor 5 is affixed with casing 1 madial wall, and tooth bar 7 is affixed with wind deflector 3 medial surfaces, start stop switch 4 is positioned at wind deflector 3 lateral surfaces, and is easy to operate.The position-limit mechanism at tooth bar 7 two ends is a travel switch 8, travel switch 8 is electrically connected with the start stop switch 4 of stepper motor, when gear 6 is run into travel switch 8, the shutdown switch action, stepper motor 5 stops, and wind deflector 3 is limited, because casing 1 width is greater than the air inlet width, when wind deflector was opened fully, slide rail and chute still had between one section contact zone.Wind deflector 3 can only be provided with one, and for attractive in appearance and maintenance weight balancing, the wind deflector 3 of present embodiment comprises symmetrically arranged two, and its electric driver mechanism also is symmetrical arranged.The glide direction of wind deflector is by motor direction of rotation decision, and for the monolithic wind deflector, glide direction can be arranged to sliding opening to the left or to the right, for two symmetrically arranged wind deflectors, is set to respectively to the left and right direction away from sliding opening.Wind deflector can adopt materials such as stainless steel or tempered glass.
