BLENDER

Proposed is a blender, in which a main body operates when a closure of the container lid on a container body is detected. In the blender according to the present disclosure, when the closure of the container lid is detected, a voltage of a preset signal pattern is applied to the first inductive coil of the main body, and the voltage is transferred to the second inductive coil of the container body by inductive coupling with the first inductive coil. The light emitting unit of the container body transmits a light signal to the light receiving unit of the main body by using the voltage transmitted to the second inductive coil, and the light signal has the signal pattern. When the light receiving unit receives the light signal of the signal pattern, the main body recognizes the closure of the container lid on the container body so that that the main body operates.
