Provided is a refrigerator and control method for refrigerator and method for opening a refrigerator door. While a user is holding an object in both hands, a door may be automatically and additionally opened using another part of a body other than hands.
Claims20
An appliance comprising:
- a cabinet having an internal space;
- a door configured to open and close at least a portion of the internal space;
- a push rod configured to move from a first position to a second position to thereby open the door;
- a driving motor configured to rotate in a first direction and a second direction,
- the driving motor being configured to provide a driving force to cause the push rod to move (i) from the first position to the second position or (ii) from the second position to the first position;
- a push rod position detector configured to detect a position of the push rod;
- and
- a controller configured to control a direction of rotation of the driving motor and a speed of rotation of the driving motor,
- wherein during a movement of the push rod from the first position to the second position,
- wherein the controller is configured to:
- rotate the driving motor at a first rotational speed in the first direction during a first opening step, and
- rotate the driving motor at a second rotational speed, which is lower than the first rotational speed, in the first direction during a second opening step.
