Abstract
A control system for a coffee brewer having a microprocessor in which the water heated in the heater tank must be a predetermined temperature before brewing. A double brewing cycle is prevented. Upon the system not being activated for a period of time, i.e., the water temperature is allowed to drop a greater magnitude for energy saving and component protection.
Claims15
A beverage brewing system for heating water and delivering heated water to a product for brewing comprising
- water heater means for receiving a supply of water, and said water heater means including a heater element for heating the water,
- delivery means operatively coupled to the water heater means and arranged for delivering a selected volume of the heated water to the product during a selected brewer cycle,
- temperature detection means for sensing the temperature of the heated water,
- controller means operatively coupled to said water heater means for controlling operation of said heater element between a condition applying heat to the water and being in an off condition, said controller means being further in operative connection to said temperature detection means for controlling said heater element,
- said controller means being coupled to said delivery means for supplying water from said water heater heated to a predetermined temperature to said delivery means, and
- actuator means connected to said controller means to selectively cause said delivery means to deliver the volume of heated water at said predetermined temperature, said controller means preventing said delivery of heated water when said water is below said predetermined temperature.
