Claims
- 1. A control system for a fabric washing machine having a movable lid for providing access to a tub assembly, comprising: program control means for controlling said fabric washing machine through a predetermined cycle of operations, said program control means having a first state at which said cycle of operations may be initiated and a second state upon completion of said cycle of operations; power supply means for said fabric washing machine and said program control means; switch means in circuit with said power supply means and said program control means, said switch means actuatable between a first conductive posture with said lid in a first condition and a second conductive posture with said lid in a second condition; first circuit means connected with said first conductive posture for energizing said program control means in said first state to control said fabric washing machine through said cycle of operations and to terminate operation thereof with said program control means in said second state upon completion of said cycle of operations; second circuit means connected to said second conductive posture and operable with said program control means in said second state and said lid in said second condition for initiating modification of said program control means to said first state to condition said program control means for initiation of a new cycle of operations whereby operability of said switch means to said second conductive posture is a prerequisite to initiating a new cycle of operations.
- 2. A control system as defined in claim 1 wherein said switch means is operable from said first to said second conductive posture responsive to opening said lid for energizing said second circuit means and advancement of said program control means from said second state to said first state.
- 3. A control system as defined in claim 2 wherein failure of said switch means to operate to said second conductive posture upon opening of said lid will prevent said conditioning of said program control means and preclude the initiation of a new cycle of operations.
- 4. A control system as defined in claim 1 and further including housing means for enclosing said program control means and effectively preventing manual modification of the state of said program control means after completion of said cycle of operations.
- 5. A control system as defined in claim 1 wherein said switch means must be made to said second conductive posture for a predetermined time period to condition said program control means for initiation of a new cycle of operations.
- 6. A control system for a fabric washing machine having a movable lid for providing access to a tub assembly, comprising: program control means for controlling said fabric washing machine through a predetermined cycle of operations; power supply means for said fabric washing machine and said program control means; structure associated with said fabric washing machine for preventing manual advancement of said program control means; switch means in circuit with said power supply means and said program control means, said switch means actuatable between a first conductive path and a second conductive path responsive to movement of said lid between closed and open postures respectively; first circuit energizing means associated with said program control means and in circuit with said first conductive path of said switch means for normally controlling said fabric washing machine through said cycle of operations; and second circuit energizing means associated with said program control means and in circuit with said second conductive path of said switch means upon completion of said cycle of operations for initiating modification of said program control means to condition said program control means for initiation of a new cycle of operations whereby opening of said lid and operability of said switch means to said second conductive path are prerequisites to initiating a new cycle of operations.
- 7. A control system as defined in claim 6 wherein said switch means includes first and second switches actuatable between first and second conductive paths responsive to movement of said lid between closed and open postures respectively.
- 8. A control system as defined in claim 7 wherein the second conductive paths of said first and second switches are in series connection and provide said second circuit energizing means to said program control means isolated from said first circuit energizing means.
