Embodiment Construction

[0018] figure 1 Several embodiments of the water heater of the present invention are illustrated.

[0019] A water heater according to the present invention comprises a water tank liner 10 in which two or more electronic anodes 11 are arranged; the electronic anodes 11 are connected to a control module.

[0020] Currently used electronic anode 11 inner tank protection water heater, only one electronic anode 11 provides cathodic protection. Especially for a water heater with a relatively large inner tank, since the number of electrons provided by a single electron anode 11 to the inner tank is limited, the inner tank will be underprotected. In order to achieve a better protection effect, sufficient number of electrons must be provided. When only one electron anode 11 is used, the length of the electron anode 11 can only be lengthened to increase the supply voltage of the electron anode 11 . And doing so has the following problems:

[0021] 1. Problems caused by lengthening t...

Abstract

The invention discloses a water heater, which comprises a water tank liner, wherein two or more electronic anodes are arranged in the water tank liner; the electronic anodes are connected with a control module; the water heater of the present invention adopts a plurality of electronic anodes instead The single electronic anode in the inner tank of the water tank has the effect of enhancing the reliability of the anti-corrosion system, more comprehensive and balanced protection, prolonging the life of the electronic anode, and reducing the difficulty of processing.

Description

technical field [0001] The invention relates to a household appliance, in particular to a water heater. Background technique [0002] Because the quality of domestic water in my country is very different from place to place and is relatively bad, the water tank of the water heater often has quality problems of being corroded and leaking. At present, the anticorrosion of water heater water tank liner has been widely used. The more popular one is the anticorrosion of magnesium rod sacrificial anode, but the consumption of magnesium rod is fast and needs to be replaced frequently. The more cutting-edge anti-corrosion technology is forced current cathodic protection. The forced current cathodic protection type water heater includes a water tank with a metal liner, the metal liner is insulated and provided with an electronic anode of an inert material, the metal liner doubles as a cathode, and the electronic anode and the metal liner are electrically connected through a polarit...
