Reset switch 42 is chosen as travel switch or close switch；405 weeks sides of guide sleeve are fixedly connected with a shifting block 4052；
In order to realize the automatic switch of refrigerator doors, corresponding control module should be also configured；
When pressing door open switch, control module controls the rotation of motor 403, and motor 403 drives screw rod 404 to rotate, screw rod
Axial movement is generated between 404 and guide sleeve 405, so that guide sleeve 405 is travelled forward, guide sleeve 405 is with movable slider 4051, to realize push rod
The pushing action of 406 pairs of chamber doors 2, chamber door 2 is open-top；
After chamber door 2 opens certain angle, when the fixed shifting block 4052 in 405 weeks sides of guide sleeve is contacted with limit switch 41；
Control module controls motor 403 and inverts, while controlling longitudinal motor and intermittent gear 201 is driven to rotate, and makes intermittent gear 201 and hinge
Arc-shaped rack 301 on chain 3 engages, by the rotation of intermittent gear 201 to further open chamber door 2；
Motor 403 inverts, and makes guide sleeve 405 start to retreat by screw rod 404, when shifting block 4052 touches reset switch 42
When, control module controls motor 403 and stalls, and completes the homing action of telescopic device 4, makes in 406 retraction telescopic device 4 of push rod；
As preferably can also being opened by the way that travel switch is arranged on arc-shaped rack 301 to control the maximum of chamber door 2
Position, or the rotation time of longitudinal motor is controlled to control the open position of chamber door 2 by the setting time relay；
After pressing door closing switch, longitudinal motor reversal passes through the arc-shaped rack 301 on intermittent gear 201 and hinge 3
Engagement, to make chamber door 2 begin to shut off；Control module can the longitudinal motor stalling of delays time to control, guarantee intermittent gear 201 and hinge
Arc-shaped rack 301 on 3 completely disengages engagement；
As the closed state that travel switch preferably can also be arranged on babinet 1 further determine chamber door 2, ensure chamber door
2 completely close.
When being not required to automatic opening and closing door, chamber door 2 can be directly pulled open manually, at this time intermittent gear 201 and the circle on hinge 3
Arc-shaped rack 301 is in the state for completely disengaging engagement；Opening the door additionally to cause between cog to wear, while also ensuring enabling
Smoothness.
Control module can also be equipped with current detection module, after the operation of chamber door 2 is restricted, motor 403 or longitudinal motor
It cannot continue to run with, then generate locked rotor current, electric current increases, and reaches given threshold, then motor 403 or longitudinal motor stop turning
It is dynamic, prevent article from causing device when blocking to generate failure chamber door 2；Scram button is may also set up, is opened or closed in chamber door 2
When Shi Fasheng emergency cases, convenient for stopping being turned on and off for chamber door 2 in time.
