  • Patent number: 4916439
    Abstract: Disclosed are two arrangements for remotely indicating the status of a washing machine and/or a dryer. In one arrangement, a current sense circuit is employed along with an optional vibration sense circuit to detect whether or not the washing machine or the dryer are on or off. At a change from on-to-off or from off-to-on, the status of the washing machine or dryer is transmitted over the air to a receiver for status display to the operator. In the second arrangement, detection of the status is internal to the washing machine and the dryer and the status includes additional information such as the type of cycle and the amount of time left before the cycle finishes. To avoid constant transmission of such information, the receiver includes a timer which is synchronized to the washing machine/dryer timing circuits.
