Variable delay appliance hybrid program timer
View Patent ↗A timer control apparatus for use in an appliance is provided. The timer control apparatus includes a timer having a timing motor, a user interface including a setting indicator and option switches, and a delay circuit associated with the timing motor. The delay circuit is operable to halt the timing motor and to start the timing motor such that the timer control apparatus delays progression of the timing motor. The delay circuit can halt and start the timing motor at regular intervals, irregular intervals, according to a timing pattern, based on the setting indicator, and/or based the option switches. By delaying the timing motor, travel or progression of the setting indicator between settings is reduced.
1. An appliance, comprising:
a cycle timer including a timing motor;
a user interface having selectable thereon at least one option switch and a setting indicator, the setting indicator having a first setting and a second setting associated therewith;
a delay circuit operably coupled to the timer and the user interface, the delay circuit operable to de-energize the timing motor to halt the timing motor after the timing motor has rotated the setting indicator a given distance from a starting position of the setting indicator wherein the timing motor rotates the setting indicator immediately after a start of operation of the appliance before a first de-energization of the timing motor and to re-energize the timing motor to start the timing motor based on a cycle input from the setting indicator and activation of the at least one option switch; and
wherein the at least one option switch on the user interface includes a light wash option switch, a medium wash option switch, and a heavy wash option switch, and wherein the delay circuit de-energizes the timing motor to halt the timing motor for a period of time based on which one of the light wash option switch, the medium was option switch, and the heavy wash option switch is activated.
2. The appliance of claim 1 , wherein the delay circuit de-energizes the timing motor to halt the timing motor after the timing motor has rotated the setting indicator the given distance from the starting position of the setting indicator only during an agitation time of a washing cycle of the appliance.
3. An appliance comprising:
a cycle timer including a timing motor;
a user interface having selectable thereon at least one option switch and a setting indicator, the setting indicator having a first setting and a second setting, associated therewith;
a delay circuit operably coupled to the timer and the user interface, the delay circuit operable to de-energize the timing motor to halt the timing motor after the timing motor has rotated the setting indicator a given distance from a starting position of the setting, indicator and to re-energize the timing motor to start the timing motor based on a cycle input from the setting of the at least one option switch;
wherein the delay circuit is operable to halt and to start the timing motor at irregular intervals according to a predetermined timing pattern based on the cycle input from the setting, indicator and the activation of the at least one option switch; and
wherein the at least one option switch on the user interface comprises a light wash option switch, a medium was option switch, and a heavy wash option switch, and wherein the delay circuit is operable to de-energize the timing motor to halt the timing motor after the timing motor has rotated the setting indicator the given distance from the starting position of the setting indicator and to re-energize the timing motor to start the timing motor based on a combination of the cycle input from the setting indicator and which one of the light wash option switch, the medium was option switch, and the heavy wash option switch is activated.
4. The appliance of claim 3 , wherein the delay circuit de-energizes the timing motor to halt the timing motor after the timing motor has rotated the setting indicator the given distance from the starting position of the setting indicator only during an agitation time of a washing cycle of the appliance.
