[0002] Electromagnetic water heaters are becoming increasingly popular in the market due to their high efficiency and safety. Their heating element typically includes an inner tank and a matching water system to achieve water inlet, heating, drainage, and sewage discharge functions.

[0003] However, existing water system designs typically treat the inlet, outlet, and sewage outlet as independent components, located separately in different positions within the inner cylinder or outer shell. This decentralized design leads to a complex overall structure, increasing product size and manufacturing costs. During installation, connecting multiple interfaces is not only cumbersome but also increases the risk of leakage due to the increased number of sealing points, affecting product reliability. Furthermore, in terms of maintenance, users must operate on each of the dispersed interfaces one by one when performing sewage discharge or repairs, which is inconvenient and makes troubleshooting difficult, thus reducing the user experience.

[0004] Therefore, in order to further improve the ease of water circuit installation and maintenance of existing heating devices, we propose a heating device for an electromagnetic water heater. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1

[0028] Reference Figure 1-3 As one embodiment of this utility model, a heating device for an electromagnetic water heater is disclosed. Specifically, the heating device includes an outer cylinder 1 and an inner cylinder 2 installed in the outer cylinder 1. Of course, in this embodiment, a mounting bracket can also be fixedly installed on the outside of the outer cylinder 1, and the outer cylinder 1 can be installed in the tank of the water heater through the mounting bracket.

[0029] A water inlet and drainage assembly 3 is installed below the inner cylinder 2. A drain pipe 4 is connected inside the water inlet and drainage assembly 3. The drain pipe 4 extends into the inner cylinder 2. A heating assembly 5 is also installed between the inner cylinder 2 and the drain pipe 4. The heating assembly 5 is used to heat the water entering the inner cylinder 2 and also to heat the water discharged along the drain pipe 4 to ensure hot water heating efficiency and hot water supply stability.

[0030] In some embodiments, the outer tube portion 21 and inner tube portion 22 of the inner cylinder 2 in this utility model are specifically described as follows: the inner cylinder 2 in this embodiment is entirely made of plastic structure to prevent electromagnetic interference and provide insulation protection.

[0031] The outer tube 21 and the inner tube 22 form an installation space 23, and the upper ends of the outer tube 21 and the inner tube 22 are closed. By adopting the upper closed structure design, water can be prevented from entering the installation space 23, thus protecting the induction coil 51 in the installation space 23.

[0032] More specifically, the heating component 5 of this utility model includes an induction coil 51 wound in the installation space 23. The wire end of the induction coil 51 extends outward along the bottom of the inner cylinder 2 and is connected to a power supply. A heating iron pipe 52 is provided between the inner tube 22 and the drain pipe 4. The heating iron pipe 52 is sleeved on the drain pipe 4. In specific operation, when the induction coil 51 is energized, electromagnetic induction is generated, and the heating iron pipe 52 is heated through electromagnetic induction. When the heating iron pipe 52 is heated, the water in the drain pipe 4 and the water between the inner cylinder 2 and the drain pipe 4 can be heated to achieve the purpose of electromagnetic heating. Of course, the drain pipe 4 can also be made of materials such as copper pipe.

[0033] Based on the above embodiments, in this embodiment, both the outer tube 21 and the outer cylinder 1 are formed with flanges 24. The two flanges 24 are fitted together and fixed by fasteners. Of course, the fasteners in this embodiment are bolts. The two flanges 24 are connected and fixed by bolts so that the entire inner cylinder 2 is installed in the outer cylinder 1. In addition, in order to enhance the connection and sealing between the two, a sealing ring can also be placed between the two flanges 24 for sealing. This method is a conventional method for those skilled in the art and will not be described in detail here.

[0034] In a further embodiment, the inner bottom of the inner tube 22 of the present invention is formed with a closed bottom surface 25, the drain pipe 4 passes through the closed bottom surface 25, and the inlet and outlet drainage assembly 3 is connected to the bottom of the closed bottom surface 25.

[0035] In some embodiments, the inlet and outlet assembly 3 of the present invention includes a connecting body 31, and an inlet 32, a drain outlet 33 and a drain outlet 34 are connected to the outside of the connecting body 31.

[0036] The drain pipe 4 and the drain outlet 34 are connected and sealed. The sealing method can be to weld the end of the drain pipe 4 to the inside of the drain outlet 34, forming a water inlet channel 35 between the connecting body 31 and the drain pipe 4.

[0037] Of course, in this embodiment, the water inlet 32 ​​and the sewage outlet 33 are interconnected, and the drain outlet 34 is connected to the drain pipe 4. It should be noted that in this embodiment, the upper end of the connecting body 31 is integrally formed and connected to the inner cylinder 2. That is, the water inlet and drainage component 3 can be designed to be integrally injection molded with the inner cylinder 2, and the connecting body 31 is formed below the closed bottom surface 25.

[0038] In actual use, the water inlet 32 ​​is connected to the water source, and the water source will enter the water inlet channel 35 between the drain pipe 4 and the connecting body 31 along the water inlet 32, and flow upward into the inner cylinder 2. At this time, the heating iron pipe 52 will heat the drain pipe 4 to achieve preliminary heating of the upward surging water flow.

[0039] As the water continues to flow upward, it enters along the upper end of the drain pipe 4, then flows downward and is discharged upward along the drain outlet 34. During the water discharge process, the heating iron pipe 52 will reheat the drain pipe 4, thus realizing the circulation heating of the water source and ensuring the stability of the hot water supply and heating efficiency.

[0040] Of course, when sewage needs to be discharged, the above-mentioned sewage outlet 33 can be opened, and the sewage can be discharged outward through the sewage outlet 33.

[0041] Example 2

[0042] Reference Figure 4 , 5 In this embodiment, the similarities with those in Embodiment 1 will not be repeated. The difference is that in this embodiment, a connection port 36 is installed on the connecting body 31, a bracket 37 is fixedly installed on the inner side of the inner cylinder 2, a connecting pipe 38 is provided below the bracket 37, the connecting pipe 38 and the connection port 36 are threadedly connected, and a clearance hole 39 is also provided on the end face of the bracket 37 to avoid the drain pipe 4.

[0043] In this embodiment, the inlet and outlet components 3 and the inner cylinder 2 are designed to be separable. The bracket 37 can be fixed to the inside of the inner cylinder 2 with bolts, and its connecting pipe 38 extends to the bottom of the inner cylinder 2. When connecting, the connecting port 36 on the connecting body 31 and the connecting pipe 38 can be fixed by threading, so as to effectively improve the assembly convenience of the inlet and outlet components 3.

[0044] In addition, in this embodiment, a sealing ring can be fitted on the outside of both the connecting pipe 38 and the connecting port 36. The sealing ring is designed to improve the sealing performance after the two are connected, so as to avoid water leakage.

[0045] Of course, the water inlet and drainage principle of this detachable structure is the same as that of Embodiment 1, and will not be elaborated further here.

[0046] In summary, this utility model integrates the water inlet 32, the sewage outlet 33, and the drain outlet 34 into a single unit by designing an inlet and drainage assembly 3 below the inner cylinder 2. This design not only features a compact structure and simplifies the pipeline layout, but also greatly improves the ease of installation and the efficiency of subsequent maintenance.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
