Abstract

The invention relates to a water heater and an electric leakage and dry burning preventing detection method of the water heater. The water heater comprises an inner container, a heating pipe, a pipe joint and a control unit, wherein the heating pipe is installed in the inner container through a heating tube flange, the pipe joint comprises an insulating piece and two metal pieces which are embedded in the insulating piece and are mutually insulated, the metal pieces which are arranged in the pipe joint and connected with the inner container are provided with conductive components, and the conductive components are led out from the insulating piece and are electrically connected with a current or voltage detection circuit in the control unit. Therefore, detection for whether electric leakage of the water heater exists can be achieved by means of the conductive components on the metal pieces contacted with the inner container, an achieving mode is simple, as long as electric leakage exists, timely alarming can be achieved, and safety and reliability are strong. Meanwhile, by means of judging whether the conductive components and conductive components on the heating tube flange are in a conductive state, whether the water heater is in a dry burning state can be judged, electrodes are not needed to be arranged inside the inner container, and structural design is simple, installation and maintenance are convenient, and cost is saved.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and in particular relates to a water heater with detection functions of electric leakage and anti-dry heating. Background technique [0002] At present, the leakage detection of the water heater usually uses an electronic transformer to detect the leakage value of the water heater, one end of which is connected to the ground wire, and when the leakage value exceeds a safe value, the leakage protector works. However, this solution cannot protect the situation that the inner tank of the water heater is accidentally electrified when the grounding wire fails to be grounded. Therefore, a safe leakage protection function cannot be achieved. [0003] The anti-dry heating of existing water heaters is generally to install an anti-dry electrode on the upper part of the heating tube, and determine whether the water heater is in a dry-boiling state by detecting whether the shell of the heating tube an...
