Touchless opening refrigerator and opening control method thereof

Abstract

The invention discloses a touchless opening refrigerator and an opening control method thereof. The refrigerator comprises a refrigeration compartment arranged at the lower part of the refrigerator, a door body used for opening and closing the refrigeration compartment, a first action sensing module used for sensing actions at a first height part within a distance range in front of the first action sensing module, and a second action sensing module used for sensing the actions at a second height part with in the distance range in the front of the second action sensing module, and a control module, wherein the second height is smaller than the first height; the control module is arranged to sense the actions in the first height and the second height simultaneously and generate a first state signal while the first action sensing module and the second action sensing module are controlled, and after a period of time, to sense the actions in the first height and the second and generate a second state signal simultaneously while the first action sensing module and the second action sensing module are controlled again, and the opening of the door body is controlled according to the first state signal and the second state signal. Compared with the prior art, the touchless opening refrigerator provided by the invention achieves automatic opening and avoids accidental injuries caused by incorrect opening.
