Abstract
A vibration detecting apparatus includes a bobbin having a moving path of desired length in an inner periphery of the bobbin; a core movable along the moving path in the inner periphery of the bobbin by vibration applied from exterior or vibration applied to the bobbin; and a coil wound on an outer periphery of the bobbin, the inductance of which being changed in accordance with the shift of the core.
Claims23
A method of detecting vibration in a vibration detecting apparatus having a core, comprising:
- detecting periodically inductances corresponding to positions of a magnetic core at predetermined time intervals;
- converting the detected inductances into frequencies;
- calculating an average frequency value of the converted frequencies;
- determining a vibrating level of a drum-typed washing machine by comparing the calculated average frequency value of the converted frequencies and a predetermined frequency value;
- and
- determining a first condition or a second condition of the washing machine based on the determined vibrating level.
A vibration detecting apparatus having a core, comprising:
- means for detecting periodically inductances corresponding to positions of a magnetic core at predetermined time intervals;
- means for converting the detected inductances into frequencies;
- means for calculating an average frequency value of the converted frequencies;
- means for comparing the average frequency value to a predetermined frequency value;
- means for determining a vibrating level is vibrating in a first direction relative to a predetermined position corresponding to the position of the core in the vibration detection apparatus at the predetermined frequency value, if the calculated average frequency value is above predetermined frequency value;
- and
- means for determining a vibrating level is vibrating in a second direction relative to a predetermined position corresponding to the position of the core in the vibration detection apparatus at the predetermined frequency value, if the calculated average frequency value is below the predetermined frequency value.
