Abstract: The Direct Electric Resistance Liquid Heater comprises a liquid heating chamber containing a plurality of electrodes. The electrodes are spaced apart to create a plurality of channels through which the liquid to be heated passes. The electrodes are each connected to a power supply by one or more switches. A controller controls the switches based upon data received from a temperature sensor, sensing the temperature of the liquid, and/or an electric current sensor, sensing the current utilized by the liquid heater. Selection of the number and spacing of the electrodes, and the number of switches, provides the controller with various current levels options to apply to the liquid to be heated. The current levels available due to the number and spacing of the electrodes and the number of switches, span the range from minimum current to maximum current such that the controller can incrementally increase or decrease the current applied to the liquid to be heated without disrupting other users of the same power source.

Abstract translation: 直接电阻液体加热器包括含有多个电极的液体加热室。 电极间隔开以形成多个通道，待加热液体通过该通道。 电极各自通过一个或多个开关连接到电源。 控制器基于从温度传感器接收的数据，感测液体的温度和/或电流传感器来控制开关，感测液体加热器使用的电流。 选择电极的数量和间距以及开关数量为控制器提供了各种电流水平选项，以应用于待加热的液体。 由于电极的数量和间隔以及开关数量而可用的电流水平跨越从最小电流到最大电流的范围，使得控制器可以递增地增加或减少施加到待加热液体的电流，而不会中断其他用户 的电源。
