1. A blender, comprising:
a jar comprising a blade module to cut an object;
a main body to receive the jar and comprising a motor to rotate the blade module; and
a controller disposed inside the main body and configured to operate the motor;
wherein the main body further comprises an outer case forming an outer structure of the main body,
wherein the outer case comprises a touch input portion on an outer surface of the outer case,
wherein a touch sensor is disposed on an inner surface of the outer case at a position corresponding to the touch input portion to detect a touch input on the touch input portion, and
wherein the controller is configured to determine an operation time period of the motor based on the touch input detected by the touch sensor, and
wherein the controller is configured to set the operation time period and a target revolutions per minute (RPM) level of the motor before the beginning of the operation of the motor, and
wherein the operation time period comprises a first time period indicating a length of time period for increasing a current rotation number to a predetermined target RPM level and a second time period indicating a length of time period for maintaining a current rotation speed of the motor at the target RPM level after reaching the target RPM level, and
wherein the first time period is shorter than the second time period, and
wherein the target RPM level is a maximum RPM level of the motor.
