Abstract
The utility model provides a flip cover transmission mechanism of a range hood, which occupies a small space, is convenient to mount and maintain and has relatively low cost. The technical scheme is that the flip cover transmission mechanism of a range hood comprises a flip cover, a rotary arm, a motor, a chain wheel, a transmission wheel, a chain, a slide rod and a slide rod seat and is characterized in that one end of the rotary arm is fixedly connected with the flip cover, and the other end is rotatably connected with a range hood shell through a rotary shaft; the rotary arm is also provided with a sliding chute; the slide rod seat is connected with the chain; the slide rod and the slide rod seat are connected with one end of the rotary arm in a sliding manner through the sliding chute; the motor is mounted on the shell through a base; an output shaft of the motor is connected with the chain wheel; the transmission wheel is rotatably mounted on the shell through a rotary shaft; the chain wheel is rotatably connected with the transmission wheel through the chain; an upper limiting switch and a lower limiting switch are mounted on the shell or a mounting plate fixedly connected with the shell.
Description
Technical field
The utility model relates to transmission mechanism, especially relates to that a kind of make to renovate can folding or rest on the kitchen hood of optional position therebetween and renovate transmission mechanism.
Background technology
The structure that traditional kitchen hood is open because exhaust fume collecting hood adopts, return wind-induced oil smoke taint of odour and directly affect the healthy of operating personnel, and pollution kitchen environment, people have developed a kind of unlatching when kitchen hood is worked for this reason, closure set petticoat pipe during inoperative, can prevent the flip cover assembly of the kitchen hood of return air taint of odour, but the transmission mechanism of the kitchen hood 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 transmission 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 that the transmission mechanism that overcomes prior art kitchen hood flip cover assembly takes up room greatly, installs and keep in repair trouble, and the defect that cost is larger, provide a kind of take up room little, easy to installation and maintenance, and cost is less, kitchen hood simple in structure is renovated transmission mechanism.
The technical scheme in the invention for solving the technical problem is: kitchen hood is renovated transmission mechanism, comprise and renovating, pivoted arm, motor, sprocket wheel, drive, chain, slide bar, slider block, it is characterized in that, one end of described pivoted arm with described in renovate and be fixedly connected with, the other end is rotatably connected by rotating shaft and fume exhaust engine housing, described pivoted arm is also provided with chute, described slider block is connected with described chain, described slide bar is connected with slider block through described chute and is slidably connected with described pivoted arm one end, described motor is arranged on described housing by support, the output shaft of described motor is connected with described sprocket wheel, described drive is rotatably arranged on housing by rotating shaft, described sprocket wheel is rotatably connected by described chain and described drive, upper limit position switch be arranged on described housing with lower position switch or the installing plate that is fixedly connected with described housing on.
Further, described drive can be sprocket wheel.
Operation 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 kitchen hood, the output shaft of motor is clockwise, in Fig. 1 for rotating counterclockwise, sprocket wheel rotates thereupon, thereby drive chain movement, because described slider block is connected with described chain, and described slide bar is slidably connected with described pivoted arm by described chute, therefore above-mentioned chain rotates and drives described pivoted arm to rotate counterclockwise, and 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 certain angle, while touching the contact that is fixedly mounted on the lower position switch 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 kitchen hood fully appears, and makes kitchen hood give full play to its fume exhaust 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, and the output shaft of motor starts reversion, in Fig. 2 for clockwise rotating, sprocket wheel rotates thereupon, thereby drive chain to rotate, because described slider block is connected with described chain, and described slide bar is slidably connected with described pivoted arm by described chute, therefore above-mentioned chain movement 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 certain angle, while touching the contact that is fixedly mounted on the upper limit position 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 kitchen hood completely, prevented that kitchen hood 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.
Fig. 3 is slider block and slide bar enlarged drawing.
