Referring to fig. 1 to 4, the water heater of the present utility model is provided with a liner, an electric heating element 20 and an electronic anode 30, wherein the liner is provided with a water containing cavity, the liner is further provided with a mounting hole, the electric heating element 20 is used for heating water in the liner of the water heater, the electronic anode 30 is used for adsorbing anions in a liquid to prevent the electric heating element 20 from oxidizing in the heating process, in order to reduce the mounting hole on the liner, and simultaneously ensure that the electric heating element 20 and the electronic anode 30 are simultaneously mounted in the liner, the water heater of the present utility model is provided with only one mounting hole, and is provided with a fixing joint 10 at the mounting hole, the fixing joint 10 is hermetically mounted at the mounting hole, and the electric heating element 20 and the electronic anode 30 are respectively fixed on the fixing joint 10 so as to be fixed on the liner through the fixing joint 10, thus the number of holes on the liner is reduced before the fixing joint 10 is mounted on the liner, and the sealing performance is improved.

Since the electric heating element 20 generally adopts a U-shaped structure similar to that of a quick heater, which has two ends on the same side, for this purpose, the present embodiment is provided with two first mounting holes 11 on the fixing tab 10, and the two first mounting holes 11 are respectively used for fixedly mounting the two ends of the electric heating element 20.

In addition to the first mounting holes 11 for fixing the electric heating element 20, the fixing joint 10 is further provided with second mounting holes 12, the second mounting holes 12 are used for mounting the electronic anode 30, and the first mounting holes 11 and the second mounting holes 12 are arranged at intervals.

In addition, as shown in fig. 2, a mounting plate is provided on the fixing joint 10, screw holes are provided around the mounting plate to be fixed on the liner by screws, a mounting groove is provided in the middle of the fixing joint 10, and the first mounting hole 11 and the second mounting hole 12 are both fixed in the mounting groove.

In order to prevent the electronic anode 30 and the electric heating element 20 from contacting and conducting and also to be in sealing connection with the fixed joint 10, as shown in fig. 3, the water heater of the present utility model further comprises an insulating sheath 40, wherein the insulating sheath 40 can be made of rubber or plastic, the insulating sheath 40 is arranged in the second mounting hole 12, and the electronic anode 30 is fixed on the insulating sheath 40 and is fixed on the fixed joint 10 through the insulating sheath 40.

In order to facilitate the sealing installation of the electronic anode 30, the second installation hole 12 is provided as a threaded hole in the embodiment, an external thread is arranged on the outer side of the insulating sheath 40, and the insulating sheath 40 and the second installation hole 12 are in threaded fit connection.

The water heater further includes a grounding assembly connected to the insulating sheath 40 and the fixed joint 10, respectively. In order to connect the grounding component with the electronic anode 30 and the fixed joint 10, a threaded hole is arranged at the end part of the insulating sheath 40, the other end of the insulating sheath 40 is deep into the water holding cavity, and a mounting hole for fixing the electronic anode 30 is arranged at the end of the insulating sheath 40, the grounding component comprises a first screw 51 and a second screw 52, and the first screw 51 is arranged at the end of the insulating sheath 40 far away from the electronic anode 30 and is fixed in the threaded hole; the second screw 52 is provided on the fixed joint 10 instead of being directly fixed to the electric heating element 20, which reduces damage to the electric heating element 20, and the second screw 52 grounds the risk of leakage of the electric heating element 20 through the fixed joint 10.

In order to ensure that the functions of the electric heating element 20 and the electronic anode 30 are successfully realized and simultaneously reduce the space occupation as much as possible, the electric heating element 20 and the electronic anode 30 are connected in an insulating way, and the electronic anode 30 is attached to the electric heating element 20.

For ease of understanding, the present utility model is further explained below with respect to the above-described electron anode 30 and electric heating element 20:

the electron anode 30 can realize the function of corrosion prevention, and the principle is that: after power-up, the electronic anode 30 can release cations, can consume corrosive anions in water, and avoid the anions in water from directly corroding the water tank liner. I.e., the electron anode 30 provides cations that are more active and more readily bind anions than the cations in the tank liner itself.

The heating element 20 is a heating element, and its own cations are easily combined with anions in water to form scale. However, if the electronic anode 30 is mounted near the heating element 20, the cations provided by the electronic anode 30 will readily and quickly protect the heating element 20 from scaling due to the close proximity. Because anions in the vicinity of the heating element 20 will preferentially combine with cations of the electron anode 30.

In summary, for air energy water heater tanks equipped with an electric heating element 20 and an electronic anode 30, it is currently practice in the industry to install the two as different modules, namely, to weld an electric heating element joint and an electronic anode 30 joint on the tank liner, and then to install, wire and run the two separately. The utility model integrates the electric heating element 20 and the electronic anode 30 into a whole, and only needs to weld the electric heating element 20 fixing joint 10 on the liner during installation, thus reducing one part, lowering the cost of the whole machine, reducing hidden danger of a water leakage point and improving the sealing performance of the whole machine. Most importantly, after the electric heating element 20 and the electronic anode 30 are integrated, the electronic anode 30 is closer to the electric heating element 20, so that the electric heating element 20 can be protected in all directions, and the risk of corrosion and scaling of the electric heating element 20 is greatly reduced. After the electric heating element 20 and the electronic anode 30 are integrated, the electric heating element is isolated by an insulating sheath 40, and is sealed by an O-shaped sealing ring 41. The insulating sheath 40 and the electronic anode 30 are integrally injection molded by a titanium rod, the outer part of the sheath is threaded, and the insulating sheath is in threaded connection with the electric heating element 20, so that the electric heating element is stable and reliable
