Abstract
Disclosed herein are a washing machine that amplifies the displacement of a tub according to input of laundry such that the displacement of the tub is accurately sensed by a sensor module and a laundry amount detection apparatus thereof. The washing machine includes a housing forming an external appearance thereof, a tub provided in the housing to contain water, an amplification unit to amplify displacement of the tub, and a sensor module to sense weight of laundry using the amplified displacement of the tub.
Claims21
A washing machine comprising:
- a housing forming an external appearance thereof;
- a tub provided in the housing to contain water;
- an amplification unit to amplify displacement of the tub;
- and
- a sensor module to sense (detect) weight of laundry using the amplified displacement of the tub.
A washing machine comprising:
- a housing;
- a tub provided in the housing to contain water;
- a lever having an output end to amplify displacement of the tub transmitted to an input end according to input of laundry into the washing machine;
- a fixing member coupled to the lever;
- and
- a sensor module configured to measure displacement of the output end of the lever to sense weight of the laundry.
A laundry amount detection apparatus of a washing machine, comprising:
- a sensor module configured to measure descent of a tub to sense weight of laundry;
- a lever configured to be rotated about a shaft to amplify the descent of the tub such that the descent of the tub is sensed by the sensor module;
- and
- a fixing member coupled to the lever,
- wherein, the lever comprises an input end fixedly mounted to the tub such that the descent of the tub is transmitted to the input end and an output end provided opposite to the sensor module.
