Abstract
Disclosed herein are a water level/vibration sensing apparatus and a washing machine having the same. The water level/vibration sensing apparatus includes a housing provided with a pressure chamber communicating with an air inlet, a diaphragm unit moving forward and backward according to the variation of a pressure in the pressure chamber, a core and a coil forming a frequency varied according to the forward and backward movement of the diaphragm unit, and a collision member striking the diaphragm unit according to the movement of the housing. Therefore, the water level/vibration sensing apparatus simultaneously senses the washing water level and the vibration of the washing machine.
