SYSTEMS AND METHODS FOR DRAIN PUMP OPERATION IN WASHING MACHINE APPLIANCES - A simplified explanation of the abstract

This abstract first appeared for US patent application 17956241 titled 'SYSTEMS AND METHODS FOR DRAIN PUMP OPERATION IN WASHING MACHINE APPLIANCES

Simplified Explanation

The abstract describes a patent application for a controller that monitors pressure, temperature, turbidity, and conductivity measurements in a washing machine. The controller activates the pump and timer during a drain cycle, compares sensor measurements to reference values, determines the presence or absence of fluid in the wash tub, and deactivates the pump accordingly.

  • Pressure sensor monitoring
  • Ambient temperature recording
  • Pump and timer activation during drain cycle
  • Turbidity, conductivity, and temperature sensor measurements
  • Comparison of sensor measurements to reference values
  • Determination of fluid presence in wash tub
  • Pump deactivation based on timer expiration or absence of fluid

Potential Applications

The technology described in this patent application could be applied to various types of washing machines and other fluid-based systems that require monitoring and control of pressure, temperature, turbidity, and conductivity.

Problems Solved

This technology solves the problem of efficiently managing the drainage process in a washing machine by accurately determining the presence or absence of fluid in the wash tub.

Benefits

The benefits of this technology include improved efficiency in the washing machine's operation, reduced energy consumption, and potentially longer lifespan of the machine due to optimized pump usage.

Potential Commercial Applications

One potential commercial application of this technology is in the development of smart washing machines that can automatically adjust their operation based on sensor measurements to improve performance and energy efficiency.

Possible Prior Art

One possible prior art for this technology could be existing washing machine systems that use sensors for monitoring water levels and temperature during the washing process.

Unanswered Questions

How does the controller differentiate between different types of fluids in the wash tub?

The abstract does not provide specific details on how the controller distinguishes between different types of fluids, such as water, detergent, or fabric softener, in the wash tub.

What is the impact of the controller's deactivation of the pump on the overall washing machine performance?

The abstract does not mention the potential consequences of deactivating the pump based on the sensor measurements, such as the effect on the washing cycle or the quality of the cleaning process.


Original Abstract Submitted

A controller is configured to monitor the pressure measurement of the pressure sensor and record an ambient temperature measurement in response to the pressure measurement stabilizing. Activate the pump and a timer in response to a drain cycle starting. The controller also configured to record a turbidity measurement from the turbidity sensor, a conductivity measurement from the conductivity sensor, and a temperature measurement from the temperature sensor and compare the turbidity measurement to a reference turbidity value, the conductivity measurement to a reference conductivity value, and the temperature measurement to the ambient temperature measurement. Then determine either a presence or an absence of fluid in the wash tub based at least in part on the turbidity measurement, the conductivity measurement, and the temperature measurement, and deactivate the pump in response to either the timer expiring or the determination of the absence of fluid in the wash tub.
