Description
Technical Field
[0001] This utility model relates to the field of electromagnetic heater technology, and in particular to a highly reliable electromagnetic heater for water heaters. Background Technology
[0002] In the field of water heater technology, electromagnetic heating technology has gradually attracted attention due to its advantages such as high efficiency, energy saving and safety. However, existing electromagnetic heaters still have many shortcomings in terms of structural design and heating efficiency.
[0003] On the one hand, traditional electromagnetic heaters mostly adopt a single heating chamber structure with a simple water flow path, making it difficult to achieve simultaneous heating of the inlet and outlet water flow, resulting in poor hot water supply stability and low heating efficiency. On the other hand, some products have complex structures and a large number of parts, which not only increases production costs but also increases assembly difficulty and the risk of leakage, affecting the long-term reliability of the products.
[0004] Therefore, in order to improve the heating efficiency and structural reliability of existing electromagnetic heaters, we propose a highly reliable electromagnetic heater for water heaters. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a highly reliable electromagnetic heater for water heaters.

[0009] And an inner cylinder installed inside the outer cylinder, with a water inlet channel formed between the outer cylinder and the inner cylinder;
[0010] A water outlet pipe is fixedly installed inside the inner cylinder, and the lower end of the water outlet pipe extends through to the bottom of the inner cylinder. A heating structure is provided between the inner cylinder and the water outlet pipe.
[0011] Furthermore, the outer tube portion and the inner tube portion of the inner cylinder;
[0012] An installation space is formed between the outer tube and the inner tube, and the upper ends of the outer tube and the inner tube are closed.
[0013] Furthermore, both the outer tube and the outer cylinder are formed with flanges, and the two flanges fit together and are fixed by fasteners.
[0014] Furthermore, the inner bottom of the inner tube is formed with a closed bottom surface, the water outlet pipe passes through the closed bottom surface, and two locking members are threaded to the outer side of the water outlet pipe, with the two locking members located on both sides of the closed bottom surface respectively.
[0015] Furthermore, the heating structure includes an induction coil wound in the installation space, and a heating iron pipe is disposed between the inner tube and the outlet pipe.
[0016] Furthermore, a sensor interface and a drain outlet are connected to the upper end of the outer cylinder, and a mounting bracket is fixedly installed on the outer side of the outer cylinder.
[0017] This invention proposes a highly reliable electromagnetic heater for water heaters. The advantages are as follows: This invention incorporates an inner cylinder within an outer cylinder, and an outlet pipe is installed within the inner cylinder. When water enters the outer cylinder, the water flows into the inner cylinder and is discharged outwards along the outlet pipe. Simultaneously, the heating structure heats both the water flowing inside the inner cylinder and the water flowing outwards through the outlet pipe, ensuring a stable hot water supply and high heating efficiency.

[0022] 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.
[0023] Reference Figure 1-3As one embodiment of this utility model, a highly reliable electromagnetic heater for a water heater is disclosed. Specifically, the electromagnetic heater includes an outer cylinder 1 with a water inlet 10; and an inner cylinder 2 installed inside the outer cylinder 1. A water inlet channel 3 is formed between the outer cylinder 1 and the inner cylinder 2, and the upper end of the inner cylinder 2 is open.
[0024] A water outlet pipe 4 is fixedly installed inside the inner cylinder 2. The lower end of the water outlet pipe 4 extends through to the bottom of the inner cylinder 2. A heating structure 5 is provided between the inner cylinder 2 and the water outlet pipe 4. The heating structure 5 is used to heat the water entering the outer cylinder 1 and can also heat the water discharged along the water outlet pipe 4 to ensure hot water heating efficiency and hot water supply stability.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] In a further embodiment, the inner bottom of the inner tube 22 in this invention is formed with a closed bottom surface 25. Of course, the closed bottom surface 25 and the inner tube 22 are integrally formed. The water outlet pipe 4 passes through the closed bottom surface 25. Two locking members 41 are threadedly connected to the outer side of the water outlet pipe 4. The two locking members 41 are located on both sides of the closed bottom surface 25.
[0029] Specifically, in this embodiment, the locking member 41 is set as a nut, which is threadedly connected to the water outlet pipe 4. Similarly, in order to improve the connection sealing of the water outlet pipe 4, a sealing gasket can also be set between the nut and the closed bottom surface 25 in this embodiment. In this way, when the two nuts on both sides are locked, the water outlet pipe 4 can be fixed and the connection sealed. In order to improve the heating effect, the water outlet pipe 4 can also be set as a metal part, such as a copper pipe with good thermal conductivity.
[0030] In some embodiments, the heating structure 5 of this utility model includes an induction coil 51 wound in the installation space 23. The end of the wire 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 water outlet pipe 4. The heating iron pipe 52 is sleeved on the outside of the water outlet pipe 4. In specific operation, when the induction coil 51 is energized, electromagnetic induction is generated, and the heating iron pipe 52 is heated by electromagnetic induction. When the heating iron pipe 52 is heated, the water in the water outlet pipe 4 and the water between the inner cylinder 2 and the water outlet pipe 4 can be heated to achieve the purpose of electromagnetic heating.
[0031] It should be noted that in this embodiment, a sensor interface 11 and a drain port 12 are connected to the upper end of the outer cylinder 1. The sensor interface 11 is used to install a temperature sensor to monitor the internal water temperature. Of course, after prolonged heating, the water outlet pipe 4 can be closed and the drain port 12 can be opened. When water is injected into the outer cylinder 1, the water can be discharged along the drain port 12 to clean the accumulated substances inside. A mounting bracket 13 is fixedly installed on the outside of the outer cylinder 1. The mounting bracket 13 is used to fix this device in the water heater tank.
[0032] In summary, this utility model incorporates an inner cylinder 2 within an outer cylinder 1, and an outlet pipe 4 is installed within the inner cylinder 2. When water enters the outer cylinder 1, the water flows into the inner cylinder 2 and is discharged outwards along the outlet pipe 4. Simultaneously, the heating structure 5 heats both the water flowing inside the inner cylinder 2 and the water flowing outwards through the outlet pipe 4, thereby ensuring the stability and efficiency of the hot water supply. This structural design is simple, effectively reducing the number of components, lowering production costs, significantly reducing the risk of leakage, and improving the overall reliability and practicality of the product.
[0033] 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.
