Problem Statement
- Washing machines are now far more sophisticated and most of them are controlled by software built into PCBs which runs like a computer program some known washing appliances include sensors for reviewing the parameters related to operations and safety features.
- Further, it is challenging for measuring pressure on the walls of high speed rotating system which is a drum of washing machine.
- The major concern includes appropriate fixing of force sensor & overcoming the sensor noise caused by the high speed rotating drum.
- The present invention is addressed the above issues in efficient manner.
Technology
- Present patent claimed a means for measuring pressure on the wall of a drum using a force sensor in a particular arrangement involving wireless module ZigBee.
- Said means consists of ZigBee wireless module & force sensor connected in a frame & plunger arrangement.
- The arrangements between force sensor & plunger are made ensuring some amount
- of free back & forth motion of the plunger system with respect to the frame.
- Sensors connected to ZigBee module & receiver of module connected to a computer outside the rotating drum.
Key Features/Value Proposition
Technical Perspective:
Sensors are arranged along the surface of the cylinder for Pressure measurement.
Industrial Perspective:
Efficiently applicable in washing machines.
