<p>A semiautomatic beverage maker (10) with a valve actuator arm (12) for manually moving a valve (14) from a stop, closed position to a brew, open position through means of a mechanical linkage (20, 32, 36). The dispenser valve is held in the open position for a preselected brew time period by means of an electromagnet (53) which is energized through a timer switch (48) until the end of the time period, and then a coil spring (50) returns the dispenser valve (14) to the open position. In an emergency, the dispenser valve actuator (12) can be used to manually return the dispenser valve (14) to the open position before de-energization of the electromagnet (53) at the end of the brew time period. The dispenser valve actuator (12) also blocks removal of the ingredient holder, or brew basket (38) from its proper brew position when the dispenser valve (12) is open during the brew cycle.</p> |
