At present, the propane gas water heater is heated by propane, with a single heat source, average heating efficiency, and no anode rod is provided in the gas water heater, so the water tank is easily corroded, resulting in problems such as a large amount of scale and peculiar smell in the water tank due to the corrosion of the water tank. Summary of the Utility Model

[0013] Compared with the prior art, the beneficial effects that the utility model can achieve are:

[0014] In the present utility model, an electric heating element is added to a gas water heater. Compared with the propane heating of a traditional gas water heater, it now becomes a dual heating source of propane and the electric heating element for combined heating, with faster heating efficiency. At the same time, an anode rod is provided at one end of the electric heating element, and the anode rod can effectively protect the water tank and reduce its corrosion degree, thereby further effectively reducing the generation of scale and odor in the water tank of the gas water heater.

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0020] As Figures 1-3 shown, the present utility model provides a novel heating structure for a gas water heater, including an electric heating element 2, and an anode rod 3 is provided at one end of the electric heating element 2;

[0021] By adding the electric heating element 2 to the gas water heater, compared with the propane heating of the traditional gas water heater, it now becomes a dual heating source of propane and the electric heating element 2 for combined heating, with faster heating efficiency. At the same time, an anode rod 3 is provided at one end of the electric heating element 2, and the anode rod 3 can effectively protect the water tank and reduce its corrosion degree, thereby further effectively reducing the generation of scale and odor in the water tank of the gas water heater;

[0022] It should be noted that only the scale and odor generated due to the corrosion of the water tank of the gas water heater are reduced here, excluding the scale and odor caused by water quality problems and pipeline pollution in the water tank.

[0023] like Figure 1 As shown, the electric heating element 2 is an electric heating tube, which can be heated by powering on, and one end of the electric heating tube is detachably connected to the anode rod 3;

[0024] By detachably arranging the anode rod 3 at one end of the electric heating element 2, when the anode rod 3 is consumed, it is convenient to replace the anode rod 3 alone, avoiding the trouble of disassembling and replacing the electric heating element 2, saving materials, and avoiding the waste of the electric heating element 2;

[0025] It should be noted that there is no electrical connection between the electric heating tube and the anode rod 3, the anode rod 3 itself is not powered, and no current passes through it. The electric heating tube is powered to achieve the heating function. The anode rod 3 mainly exists to protect the gas water heater. The specific working principle of the anode rod 3 is the cathodic protection method of the sacrificial anode. This is the existing principle and will not be elaborated here.

[0026] like Figures 1-3 As shown, a bolt 5 is movably penetrated along the length direction of the anode rod 3 (the length of the bolt 5 is longer than the length of the anode rod 3), a connector 4 is provided at one end of the electric heating element 2, a threaded hole 41 adapted to the bolt 5 is opened at one end of the connector 4, and the bolt 5 penetrates the anode rod 3 and enters the threaded hole 41;

[0027] Specifically, a through hole is opened along the length direction of the anode rod 3 from one end, a bolt 5 is passed through the through hole and one end protrudes out of the anode rod 3, and the protruding part of the bolt 5 is screwed into the threaded hole 41, so that the bolt 5 is fixed in the connector 4, that is, the anode rod 3 is fixed, and no matter which part of the anode rod 3 is consumed, it will be relatively stably on the bolt 5. When the anode rod 3 is consumed and a new anode rod 3 needs to be added, the bolt 5 is screwed out to separate it from the connector 4, and then the new anode rod 3 is inserted and the bolt 5 is screwed back into the threaded hole 41 of the connector 4 to complete the rapid addition of the new anode rod 3.

[0028] like Figure 1 and Figure 3 As shown, a nut 6 is provided between the anode rod 3 and the connector 4, and the nut 6 is threadedly connected to the bolt 5;

[0029] When the heating structure is installed in the gas water heater, the gas water heater is installed in a motorhome instead of indoors, so a certain degree of earthquake resistance is required. By adding a nut 6 between the connector 4 and the anode rod 3, the tightness of the connection is improved.

[0030] like Figure 1 and Figure 2 As shown, a fixing member 1 is provided at the other end of the electric heating member 2;

[0031] By providing the fixing member 1, it is convenient to install the heating structure on the water tank inner tank of the gas water heater through the fixing member 1.

[0032] Specifically, the electric heating element 2 is detachably connected to the fixing member 1. Here, the electric heating element 2 can be threadedly connected to the fixing member 1. A stud can be provided at one end of the electric heating element 2, and a screw hole adapted to the stud can be opened at one end of the fixing member 1 (not shown in the figure). When the electric heating element 2 is damaged, it is convenient to disassemble and replace it. The fixing member 1 is provided on the inner wall of the water tank of the water heater, and preferably is also provided on the inner wall of the water tank of the water heater by threaded connection.

[0033] The material of the electric heating tube is stainless steel, and the material of the anode rod 3 is magnesium or zinc.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
