摘要： An oven door lock for self-cleaning ovens is described. The oven door lock includes a clutch mechanism which locks and unlocks the oven door at substantially different temperatures, in particular, the lock temperature is substantially higher than the unlock temperature. The clutch mechanism comprises a thermally responsive element, a clutch, and a lock member. During heating, in a self-clean or normal cooking operation, an expanding thermally responsive element, acting upon the clutch, causes the lock member to lock the oven door. During cool down, the contracting thermally responsive element, acting upon the clutch in an opposing direction, in concert with a restraining spring, causes the lock member to unlock the oven door at a temperature substantially lower than the locking temperature.

摘要： A refrigeration and active damper control circuit uses a single-pole thermostatic switch to control the damper motor for the fresh food compartment of a refrigeration unit. When the thermostatic switch is closed, the control circuit connects current from the electrical power source directly to the damper motor through the thermostatic switch; when the thermostatic switch is open, the control circuit connects current from the electrical power source through the evaporator fan motor and then through the damper motor. The damper motor has an electrical resistance substantially larger than that of the evaporator fan motor, so that during the latter series connection of the evaporator fan motor and damper motor, a sufficient voltage drop develops across the damper motor so that the damper will be closed by the damper motor. Since the evaporator fan motor is used to connect current to the damper motor when the thermostatic switch is open, it is not necessary to use a dual-pole thermostatic switch to control the damper motor. Rather, only a single-pole thermostatic switch will suffice. This substantially reduces the cost of the control circuit, and may also improve reliability.

摘要： An apparatus for rotationally adjusting a cam, that includes an adjustment pinion having a number of missing teeth that couple to an integral gear formed on a rotatable cam. The adjustment pinion is used to manually adjust the angular position of the rotatable cam relative to the rotatable cam's axis of rotation. When the missing teeth of the adjustment pinion disengage from the gear integral to the cam, rotation of the adjustment pinion ceases. The adjustment apparatus may be readily incorporated into a programmer/timer.

摘要： An oven door lock for self-cleaning ovens is described. The oven door lock includes a manually operated latch mechanism moveable from an unlatched state. In the latched state, a thermally responsive element is provided with a pin adapted to be received in a hole defined in the latch mechanism to lock the latch mechanism in the latched state during self-cleaning operation. The oven door lock is provided with a nuisance latch which prevents the latch mechanism from being moved to the latched state during non-self-cleaning use of the oven. A switch is provided to indicate when the latch mechanism is in the latched state. An insulation pad is sandwiched between the switch and a mounting bracket of the oven door lock to thermally and electrically insulate the switch from the oven door lock.

摘要： A hand dryer timer having a switch in electrical communication with, and controlling the operation of a heater, a fan motor and a timer motor which are electrically connected to two nonneutral lines of a power source. A cam is mounted on a drive shaft of the timer motor such that the cam rotates with the drive shaft and also slides longitudinally over the drive shaft. The cam has a cam lobe adjacent an actuating arm of the switch. A biasing element is located between the timer motor and the cam and biases the cam to a first position aligning the cam lobe with the actuating arm of the switch. The switch includes two sets of switch contacts in a power circuit for the heater and fan motor, so that at the end of a drying cycle, the two sets of switch contacts are effective to electrically isolate the heater and fan motor from both non-neutral lines of the power source.

摘要： A dryer timing control circuit includes a heater rated to operate at 240 volts and having one side connected to power. A thermostatic switch is connected between power and the other side of the heater. The thermostatic switch closes in response to a lower temperature in the dryer and opens in response to a higher temperature in the dryer. A timer motor rated to operate at approximately 240 volts has a first input connected to power. A timer motor switch operable by the timer motor has a first switch state connecting the timer motor to the heater without an intervening voltage dropping resistor. The timer motor operates in response to the timer motor switch being in the first state and the thermostatic switch being open, thereby applying 240 volts across the timer motor. The timer motor operation is terminated in response to the timer motor switch being in the first state and the thermostatic switch being in the closed state. In a second state, the timer motor switch connects the timer motor directly to 240 volts. In another embodiment, the timer motor is rated to operate at both 120 volts and 240 volts The timer motor switch in its first state operates the timer motor at 240 volts as described above, however, in its second state, the timer motor switch connects the timer motor directly to 120 volts.
