WATER LEVEL/VIBRATION SENSING APPARATUS OF A WASHING MACHINE AND A WASHING MACHINE INCLUDING THE SAME, CAPABLE OF DETECTING A WORKING STATUS BY CONTINUOUSLY CHANGING A FREQUENCY BY A COLLISION MEMBER WHICH APPLIES IMPACTS TO A DIAPHRAGM

摘要

PURPOSE: A water level/vibration sensing apparatus of a washing machine and a washing machine including the same are provided to detect the unbalanced status of a tub and the working status of a main body together and to accurately detect malfunction according to a vibration status.;CONSTITUTION: A water level/vibration sensing apparatus comprises a housing(31) wherein a pressure chamber(35) communicated with an air inlet(33) is formed, a diaphragm(40) which move forwards and backwards according to the pressure gradient of the pressure chamber, a core and a coil(38) which form the frequency changed according to the movement of the diaphragm, and a collision member(50) which is accepted in the receiving part and strikes the diaphragm according to the movement of the housing. A receiving part(60) is formed in the pressure chamber. One side of the receiving part is opened.;COPYRIGHT KIPO 2010
