  • Patent number: 11078619
    Abstract: A treating apparatus for drying articles according to a predetermined cycle of operation. The treating apparatus includes a cylindrical drum having a circumferential wall, a pair of non-anode baffles spaced on the circumferential wall, and a third baffle positioned between the pair of non-anode baffles on the circumferential wall comprising an anode element having an anode contact point at the circumferential wall. The treating apparatus also has a first cathode element disposed between the third baffle and one of the pair of non-anode baffles along the circumference of the circumferential wall and a second cathode disposed between the third baffle and the other of the pair of non-anode baffles along the circumference of the circumferential wall. The treating apparatus also has a radio frequency (RF) generator coupled to the anode element and to the first and second cathode elements.

  • Patent number: 10049555
    Abstract: The disclosure reveals a system for detecting moisture or water in a particular location. The system may incorporate a moisture detector having a control module connected to an appliance, a moisture detection circuit connected to the control module, and a voltage source connected to the moisture detection circuit and to the control module. The voltage source and the moisture detection circuit may provide voltage levels to the control module when the moisture detection circuit detects dry or wet conditions, or conditions between those conditions. A voltage level to the control module may indicate whether the appliance, such as a water heater, a washing machine, or a dish washer, has a leak. If the leak is deemed by a voltage level from the circuit to be worthy of concern, then a display, an alarm, message, or other notice mechanism may indicate an issue or what action needs to be taken.

  • Patent number: 9200842
    Abstract: A device and method are provided for detecting a root moisture content of clothing in a clothes dryer. The dryer has two conducting bars situated in the dryer bin. A pulse generator circuit is coupled to the conducting bars. A microcontroller is coupled to an output of the pulse generator circuit. The pulse generator circuit generates a pulse when wet clothing contacts the conducting bars in the dryer bin. The microcontroller receives the pulses and counts the pulses that are longer than a threshold length. The microcontroller issues a termination signal based on the number of counted pulses.

  • Patent number: 5467077
    Abstract: A display is provided for indicating changes between first and second operating conditions in an appliance such as a clothes dryer. A sensing circuit senses changes in operating conditions within the appliance. The sensing circuit creates an intermittent sensing signal which is sent to a light. The light blinks at a frequency corresponding to the frequency of the sensor signal. A second light remains lit continuously during the operation of the appliance.
