Abstract

The invention discloses a water heater and a detecting device and method of the water heater. The water heater comprises a water inlet pipe, a water flow sensor arranged on the water inlet pipe and amagnesium metal structure arranged in the water flow sensor. The detecting device is electrically connected between the magnesium metal structure and the outer wall of the water inlet pipe and comprises a resistor and a current detecting circuit, wherein the resistor is connected between the magnesium metal structure and the outer wall of the water inlet pipe in series, and the current detecting circuit is connected with the resistor in parallel. The current detecting circuit is used for obtaining a current signal flowing through the resistor, and the current detecting circuit generates and outputs a magnesium replacing message when detecting that the current signal is smaller than a minimum protective current value. The detecting device and method of the water heater achieve protection ofa water heater pipeline and detection of consumption of the magnesium metal structure in the water heater.

Description

Technical field [0001] The embodiment of the present invention relates to water heater protection technology, in particular to a water heater and its detection device and method. Background technique [0002] Water heater refers to a device that uses various physical principles to increase the temperature of cold water into hot water within a certain period of time. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic water heaters, air energy water heaters, heating water heaters, etc. [0003] The water heater's water pipeline is mainly made of phosphorous deoxidized copper (TP2), and there is no metal that is more active than copper. Although copper has certain anti-corrosion ability, because the water quality of various regions contains more and more various metal and non-metal ions, it accelerates the electrochemical corrosion of the water delivery pipeline in the water heater, causing the water deli...
