Abstract:
Disclosed is a vibration sensing apparatus and a washing machine having the same. The vibration sensing apparatus includes a variable resistor having variable resistance values according to each displacement, a displacement transmission unit interposed between the variable resistor and a vibrating body for transmitting each displacement of the vibrating body to the variable resistor, and a vibration detector for detecting each vibration of the vibrating body based upon the changes in the resistance values of the variable resistor. The vibration generated while operating the washing machine can be sensed in real time to prevent collision and noise from being generated due to excessive vibration.
