The arrangement modes in the above embodiments can all make the upper liner 11 and the lower liner 12 both have the anti-corrosion part 20, so as to improve the anti-corrosion protection effect on the liner 10.
Furthermore, one of the first protective electrode 21 and the second protective electrode 22 is an electronic anode, and the other is a sacrificial anode, wherein the corrosion potential of the electronic anode (the corrosion potential can indicate that it is relatively difficult for metal to lose electrons, and the more negative the corrosion potential is, the more easily it loses electrons) is lower than that of the sacrificial anode, that is, the electronic anode loses electrons more easily than the sacrificial anode and is corroded, so that the cathode (the inner container 10) is protected. Therefore, when the water heater is in a power-on state, the electronic anode works under the power-on action, forms a primary battery with the water and the inner container 10 to replace the inner container 10 to be corroded, plays a role in protecting the inner container 10, and is insulated from the inner container 10 at the moment; when the water heater is in a power-off state, the electronic anode does not work, and at the moment, the sacrificial anode, the water and the inner container 10 form a primary battery to replace the inner container 10 to be corroded, so that the inner container 10 is protected. So, even make electron anode unable during operation under the water heater outage circumstances, also can protect inner bag 10 through sacrificing the anode, thereby make inner bag 10 all be in the state of being protected at all times, show to improve the anticorrosion protection effect to water heater inner bag 10, help prolonging inner bag 10's life.
The electron anode is in the anticorrosion course of work for the inner bag 10 provides electron under the on-state, can choose for use the lower material of corrosion potential, in the embodiment of the utility model provides an in, the electron anode includes titanium substrate and the iridium tantalum alloy coating of cladding in the titanium substrate outside, wherein, iridium tantalum alloy coating can be formed on titanium substrate surface through the mode of sintering.

By mounting the corrosion prevention member 20 on the end cap assembly 40, the number of openings of the casing of the inner container 10 is reduced, so that the influence on the sealing performance of the casing of the inner container 10 is reduced. For example, when the corrosion prevention member 20 includes a plurality of first protective electrodes 21 respectively provided in the plurality of inner containers 10, it is preferable that the corrosion prevention member 20 is mounted on the end cap assembly 40, and when the corrosion prevention member 20 includes at least one first protective electrode 21 penetrating at least two inner containers 10, it is preferable that the corrosion prevention member 20 is mounted on a side wall of one inner container 10 and extends toward an adjacent inner container 10 to be simultaneously provided in the plurality of inner containers 10.
Further, the heater of the storage water heater is generally installed through a flange, and specifically, the end cap assembly 40 includes a side end cap (not shown) and a flange (not shown), the side end cap is disposed at one end of the inner container 10; the flange is arranged on one side of the side end cover far away from the inner container 10; wherein the corrosion prevention member 20 is provided on the side end cap, or the corrosion prevention member 20 is provided on the flange. When the anti-corrosion element 20 is mounted on the side end cap or the flange, only the mounting holes need to be correspondingly formed on the side end cap or the flange.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
