Abstract: Proposed is a home appliance that includes a cabinet defining an exterior of the home appliance, a reception space defined inside the cabinet and configured to receive objects in the reception space, a door configured to open and close an open surface of the reception space, the door having a viewing window provided at the door, a sensor assembly configured to detect each of a plurality of vibrations transmitted in three axial directions orthogonal to each other and to determine whether one or more of the plurality of vibrations is generated by a user's knock, a lamp configured to illuminate an inside of the reception space, and a controller configured to turn on/off the lamp based on a knock-on signal output by the sensor assembly.

Abstract: A latch module for controlling an opening and a closing of a door of an appliance includes a latch, a spring that applies an elastic force to the latch, a motor; and a cam that contacts a contact surface of the latch and is coupled to the motor to drive the cam to pivot the latch. The cam includes a first radius, a second radius, and a third radius in a circumferential direction at an outer circumference of the cam. The latch is positioned at a first basic position when the first radius of the cam contacts the contact surface of the latch, positioned at a second basic position when the second radius of the cam contacts the contact surface of the latch, and positioned at a third basic position when the third radius of the cam contacts the contact surface of the latch.
