The refrigerator drawer is characterized in that the movement track is fixed, and the slipping phenomenon cannot occur.
A ball screw: the transmission element has small friction resistance and has the function of converting rotary motion into linear motion, the motor drives the transmission element to rotate, and the rotary motion is converted into the linear motion to realize the automatic opening and closing of the refrigerating chamber drawer;
bearing: the ball screw is supported to rotate, so that the friction coefficient in the movement process is reduced, the rotation precision is ensured, meanwhile, the transmission element is supported, and the power consumption is reduced;
a guide sensor: the guide sensor in the product realizes the effect of transferring force to the refrigerating chamber drawer and the refrigerator door under the combined action of the ball screw and the bearing by conducting according to the determined direction;
a motor: the power source provides power for the ball steel wire;
bevel gears: the two bevel gears are meshed with each other and are used for transmitting the motion and the power of the rod and the ball screw;
a switch: and controlling the motor to start and stop.
The working process is as follows:
1. refrigerating chamber drawer:
the switch button → the motor forward rotation → the ball screw → (guide sensor →) the refrigerator compartment drawer 1;
the switch button → the motor reverse → the ball screw → (guide sensor →) the refrigerator compartment drawer 2;
2. refrigerator door-to-door:
a switch button → motor forward rotation → a ball screw → a (bearing and guide sensor →) bevel gear → a refrigerator cabinet door I;
the switch button → the motor rotates reversely → the ball screw → the (bearing, guide sensor →) bevel gear → the second refrigerator door.
After adopting foretell structure, refrigerator drawer and cabinet door have automatic switch button control, not only there is the independent control refrigerator to the door, the drawer of refrigerator walk-in can also be controlled alone, in addition there is always closed the switch, can close the drawer and the cabinet door of refrigerator walk-in simultaneously, can not have the thing and can't open the cabinet door in the hand during use, also can not be because of closing the not tight refrigerator cabinet door with insufficient effort and a large amount of air conditioning of scattering, increase the refrigerator energy consumption, do not worry more that the phenomenon that can not open the refrigerator or fall down can appear, factor of safety is higher more favorable to the house use.
