Embodiment Construction
[0040] figure 1 An embodiment of an instant boiling water heater 10 is shown. The water heater 10 includes a water tank 12 filled with water W up to a predetermined water level L. As shown in FIG. The water tank 12 includes an inlet 12a for tap or relatively cool water, and an outlet 12b for boiling or hot water, the latter connected to a faucet or other user activated flow control valve (not shown). The electric heating element 14 is arranged inside the water tank 12 and close to the bottom of the water tank 12 . A temperature sensor is likewise arranged in the water tank 12 , the temperature sensor being in the form of a thermistor 16 .
[0041] The heating element 14 and thermistor 16 are connected to a controller 18, such as a programmable logic controller (PLC) or the like. The controller 18 receives power from an electrical outlet 20 . A water inlet control valve 22 is also connected to the controller 18 . The water inlet 22 a of the control valve 22 receives tap wa...

A method for determining the working water temperature of a boiling water heater (10), the method comprising the following steps: (a) adding water to a water tank (12) to a predetermined water level; (b) making the heating device (14) inside the water tank (12) ) power on to heat the water in the water tank (12) to an initial predetermined temperature; (c) when reaching the initial predetermined temperature, power off the heating device (14), and measure the initial overshoot temperature difference beyond the initial predetermined temperature; ( D) calculating another predetermined temperature is the sum of the predetermined amount of the initial overshoot temperature difference and the initial predetermined temperature; (e) wait until the temperature of the water in the water tank (12) has been reduced by the predetermined drop from the initial predetermined temperature; (f) make The heating device (14) inside the water tank (12) is energized to heat the water in the water tank (12) to another predetermined temperature calculated in the previous step (d); (g) when reaching another predetermined temperature, make The heating device (14) is powered off, and measures another overshoot temperature difference beyond this other predetermined temperature; the sum of the predetermined temperatures; (i) wait until the temperature of the water in the tank (12) has decreased by a predetermined drop from another predetermined temperature in step (h); (j) continue steps (f) to (i) until Another overshoot temperature is substantially equal to the predetermined temperature, thereby becoming the boiling calibration temperature; and (k) subtracting the offset temperature from the boiling calibration temperature of step (h), thereby determining the operating water temperature.
Description
technical field [0001] The present invention relates to a water heater and method of operation thereof. More specifically, the present invention relates to a method of determining an operating water temperature of a boiling water heater and a boiling water heater suitable for determining the operating water temperature. [0002] The present invention is mainly developed for boiling water heaters, and the present invention will be described below in conjunction with this application. However, it is understood that the present invention is not limited to a specific field of application, and is also suitable for application in, for example, combined water heaters and water cooling units. Background technique [0003] Depending on (different) atmospheric conditions, water boils at different temperatures. The higher the altitude, the lower the air pressure and the resulting lower boiling temperature of the water. For best performance and highest customer satisfaction, at a giv...
