Abstract
The utility model provides a three-arm-type cooker hood flap transmission mechanism which is simple in structure, small in occupied space and convenient to install and maintain. The three-arm-type cooker hood flap transmission mechanism comprises a flap, a rocker arm, a motor, a motor base, a connecting rocker arm and a main rocker arm, and is characterized in that the motor base is fixedly installed inside a shell of a cooker hood, the motor is fixedly installed on the motor base, one end of the main rocker arm is fixedly connected with an output shaft of the motor, the other end of the main rocker arm is in rotatable connection with one end of the connecting rock arm through a main arm shaft pin, the other end of the connecting rocker arm is in rotatable connection with one side of the rocker arm through a rocker arm shaft pin, one end of the rocker arm is in rotatable connection with the shell through a positioning shaft, the other end of the rocker arm is fixedly connected with the flap, and a closed limiting switch and an open limiting switch are installed on the shell or an installation plate fixedly connected with the shell.
Description
Technical field
The utility model relates to fume exhaust fan and renovates driving mechanism, especially relates 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, if 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 trouble and cost larger.
Summary of the invention
Technical problem to be solved in the utility model 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 technical scheme in the invention for solving the technical problem is: 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 described one end that is connected pivoted arm by 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 with described in renovate and be fixedly connected with, 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 utility model 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 one 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 to rotate counterclockwise, rotating counterclockwise described in drive of pivoted arm renovated and rotated 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 being fixedly mounted on described housing, the signal that 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 enters 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 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 one 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 to clockwise rotate, and clockwise rotating described in drive of pivoted arm renovated and clockwise rotated.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 enters of fume exhaust fan completely, prevented that fume exhaust fan from returning cigarette taint of odour.
When renovating the arbitrary position resting in above-mentioned unlatching or closing process described in need make, described, renovate Push switch while being docked to this position, motor stops operating, described in renovate and rest on this position.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment structural representation while renovating closed condition.
Fig. 2 is the utility model embodiment structural representation while renovating opening state.
