A door opening device, a refrigerator (100), and a non-contact door opening method. The door opening device for the refrigerator (100) comprises: an operation detection module (20), configured to generate one or more operation signals according to an external operation at the front part of the operation detection module (20); a human body sensing module (60), configured to generate a human body sensing signal when a human body is sensed in a sensing range of the human body sensing module (60); and a control module (30), configured to control the starting of the operation detection module (20) when the human body sensing signal is received, and generate a door opening instruction according to one or more operation signals. In the door opening device, the refrigerator (100) and the non-contact door opening method, because of the provision of the human body sensing module (60) and the operation detection module (20), the refrigerator opens only when a human body is near the refrigerator, detection of a user operation action being used to open the door; thus, an inadvertent door-opening operation caused by a distant user performing an operation that can open the door can be prevented; it can also be ensured that the door opens only when a user stands near the door. |
