摘要： A method and apparatus for predicting load unbalance in an appliance is provided for an appliance having a vessel configured to receive a supply of material and rotatable about an axis. A control is arranged and configured to rapidly accelerate a rotation of the vessel, determine an amount of energy with which the vessel has engaged the relatively stationary part, compare the amount of energy with a predetermined value and send a signal indicative of an unbalance condition if the amount of energy exceeds the predetermined value. The vessel may be rotated by use of an electric motor such as a controlled induction motor and the control can be used to measure the electric current drawn by the motor and through manipulation of the current, determine the amount of energy with which the vessel engages the stationary part of the appliance.

摘要： A hybrid control for a clothes dryer which combines an electromechanical timer and a microprocessor. The electromechanical timer has a plurality of switches connected to a plurality of input ports of the microprocessor. The timer switches are driven by a plurality of cams such that the plurality of switches open and close in response to the cams at predetermined angular positions of the timer. In this manner, the switches provide control input to the electronic circuit for initiating the dry cycle and further provide control input to the electronic circuit during the dry cycle such that the electromechanical timer and the electronic circuit operate together to control the dryer operation. In addition, a sensor supplies a signal to the microprocessor corresponding to the moisture level of the clothes within the drum. If the dryer is operated in an automatic cycle of operation, the microprocessor operates to control operation of the clothes dryer in response to the initial timer position and advances the timer in response to the moisture sensor signal such that cycle status information corresponding to the sensed moisture level is displayed by the position of the timer knob. The microprocessor operates to drive the timer at different speeds depending on the cycle selection and control settings. The duration of the automatic dry cycle is responsive to the moisture level selected, the temperature level selected and the duration of the initial moisture sensing drying period.

摘要： A method and apparatus for determining load unbalance in an appliance is provided for an appliance having a vessel configured to receive a supply of material and rotatable about an axis. A control is arranged and configured to accelerate a rotation of the vessel between a series of constant rotational speeds, measure an amount of current with which the motor draws in rotating the vessel at each of the rotational speeds and during each acceleration period, compare the amount of current with a calculated threshold value for each speed and each acceleration period and send a signal indicative of an unbalance condition if the amount of energy exceeds the precalculated threshold value. The vessel may be rotated by use of an electric motor such as a controlled induction motor and the control can be used to measure the electric current drawn by the motor. The threshold values can further be adjusted by comparing the actual line voltage supplied to the motor with a predetermined nominal line voltage.

The electromechanical timer has a plurality of switches connected to a plurality of input ports of the microprocessor. The timer switches are driven by a plurality of cams such that the plurality of switches open and close in response to the cams at predetermined angular positions which define control positions of the timer. In this manner, the switches provide control input to the electronic circuit for initiating the dry cycle and further provide control input to the electronic circuit during the dry cycle such that the electromechanical timer and the electronic circuit operate together to control the dryer operation. The timer is arranged such that a change from one control position to an adjacent control position results in only one switch being either opened or closed.
