  • Patent number: 10794742
    Abstract: A fluid sensing system includes a sensing element having a positive temperature coefficient of resistance. The system also includes a switch which is switchable between an open position which prevents current from passing and a closed position which permits current to pass. An inductor is connected electrically in series between the switch electric output and the sensing element and a diode is connected electrically in series between the sensing element and the inductor such that an output of the diode is between the switch and the inductor. A hysteretic controller changes the switch from the open position to the closed position when current passing to the sensing element falls to a lower current threshold and changes the switch from the closed position to the open position when current passing to the sensing element rises to an upper current threshold. A voltmeter measures voltage across the sensing element.

  • Publication number: 20130314234
    Abstract: A method for warning of a residual amount of liquid detergent includes: calculating a total use amount of liquid detergent by adding up a use amount of liquid detergent whenever a washing process is performed; and comparing the total use amount of liquid detergent to a reference amount, and warning of a residual amount of liquid detergent according to the comparison result. Accordingly, a user does not need to frequently check the residual amount of liquid detergent, and may easily fill up a container with the liquid detergent. Furthermore, since a sensor for sensing the residual amount of liquid detergent is not installed, it is possible to reduce the manufacturing cost of the washing machine and to prevent a user from getting an electric shock from a current leaking to the container.
