Abstract
The invention provides a three-arm ventilator flip transmission mechanism with simple structure, small occupied space and convenience in installation and maintenance. The three-arm ventilator flip transmission mechanism comprises a flip, a rotating arm, a motor, a motor base, a connecting rotating arm and a main rotating arm. The three-arm ventilator flip transmission mechanism is characterized in that the motor base is fixedly arranged in a shell of a ventilator, and the motor is fixedly arranged on the motor base; one end of the main rotating arm is fixedly connected with an output shaft of the motor, the other end of the main rotating arm is connected with one end of the connecting rotating arm through a main arm shaft pin in a rotating manner, and the other end of the connecting rotating arm is connected with one side of the rotating arm through a rotating arm shaft pin in a rotating manner; one end of the rotating arm is connected with the shell in a rotating manner through a locating shaft, and the other end of the rotating arm is fixedly connected with the flip; a closing limit switch and a starting limit switch are arranged on the shell or on an installing plate fixedly connected with the shell.
Description
Technical field
The present invention relates to fume exhaust fan and renovate driving mechanism, especially relate to that a kind of make to renovate can folding or rest on the three arm type fume exhaust fan of arbitrary position therebetween and renovate driving mechanism.
Background technique
The structure that traditional fume exhaust fan is open because exhaust fume collecting hood adopts, return wind-induced oil smoke taint of odour and directly affect the healthy of operator, and pollution kitchen environment, people have developed the flip cover assembly that can prevent the fume exhaust fan of return air taint of odour for this reason, make to open when fume exhaust fan is worked, the exhaust fume collecting hood of closing during inoperative, but the driving mechanism of the fume exhaust fan flip cover assembly of prior art is very complicated, as application number is 201010019503.5, the patent of " a kind of range hood " by name, its driving mechanism includes turbine, scroll bar, first connecting rod and connecting rod, wherein turbine and scroll bar engagement, the output shaft fixed connection of scroll bar and reducing motor connects, one end of first connecting rod is connected with turbine, the other end and connecting rod are hinged, connecting rod is packed on exhaust fume collecting hood.This transmission device make it take up room greatly, install and keep in repair the trouble and cost larger.
Summary of the invention
Technical problem to be solved by this invention is the defect that the driving mechanism that overcomes prior art fume exhaust fan flip cover assembly took up room greatly, and installed and keeped in repair trouble, provides a kind of three arm type fume exhaust fan simple in structure, that take up room little, easy to installation and maintenance to renovate driving mechanism.
The technological scheme that the present invention solves its technical problem is: the three arm type fume exhaust fan is renovated driving mechanism, comprise and renovating, pivoted arm, motor, motor cabinet, connect pivoted arm, main pivoted arm, it is characterized in that, described motor cabinet is fixedly mounted in the housing of fume exhaust fan, described motor is fixedly mounted on described motor cabinet, one end of described main pivoted arm is fixedly connected with motor output shaft, the other end of described main pivoted arm is rotatably connected with a described end that is connected pivoted arm by the principal arm pivot pin, the other end of described connection pivoted arm is rotatably connected by a side of pivoted arm pivot pin and described pivoted arm, one end of described pivoted arm is rotatably connected by positioning shaft and described housing, the other end of described pivoted arm is fixedly connected with described renovating, closed limit switch and unlatching limit switch be arranged on described housing or the mounting plate that is fixedly connected with described housing on.
Working principle of the present invention is, as shown in Figure 1, when the signal of renovating is opened in the circuit control system input of fume exhaust fan, the output shaft of motor is clockwise, in Fig. 1 for rotating counterclockwise, main pivoted arm rotates thereupon, the pivoted arm motion thereby band is dynamically connected, because the pivoted arm end of the described connection pivoted arm side by pivoted arm pivot pin and described pivoted arm is rotatably connected, and an end of described pivoted arm is rotatably connected by positioning shaft and described housing, therefore above-mentioned connection pivoted arm motion drives described pivoted arm and rotates counterclockwise, described the renovating of drive that rotate counterclockwise of pivoted arm rotates counterclockwise.When described renovating turns to certain position, be that described pivoted arm turns to several angle, while touching the contact of the unlatching limit switch be fixedly mounted on described housing, the signal that the circuit control system output motor stops operating, motor stops operating, and renovates and has arrived the enable possition of setting, it is residing position in Fig. 2, now the mouth that advances of fume exhaust fan fully appears, and makes fume exhaust fan give full play to its lampblack suction exhausting effect, and suction is oil smoke to the greatest extent.
As shown in Figure 2, after the oil extraction of cooker hood end-of-job, the signal of renovating is closed in circuit control system output, motor output shaft starts reversion, in Fig. 2 for clockwise rotating, main pivoted arm rotates thereupon, the pivoted arm motion thereby band is dynamically connected, because the pivoted arm end of the described connection pivoted arm side by pivoted arm pivot pin and described pivoted arm is rotatably connected, and an end of described pivoted arm is rotatably connected by positioning shaft and described housing, therefore above-mentioned connection pivoted arm motion drives described pivoted arm and clockwise rotates, and described the renovating of drive that clockwise rotate of pivoted arm clockwise rotates.When described renovating turns to certain position, be that described pivoted arm turns to several angle, while touching the contact that is fixedly mounted on the closed limit switch on described housing, the signal that circuitry control system output motor stops operating, motor stops operating, and renovates and has arrived the closed position of setting, i.e. residing position in Fig. 1, hidden the mouth that advances of fume exhaust fan fully, prevented that fume exhaust fan from returning the cigarette taint of odour.
When need make the described arbitrary position rested in above-mentioned unlatching or closing process of renovating, described, renovate Push switch while being docked to this position, motor stops operating, and described renovating rest on this position.
The accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation while renovating closed condition.
Fig. 2 is embodiment of the present invention structural representation while renovating opening state.
