Description

Technical Field

[0001] This utility model relates to the field of hot water boiler technology, specifically to an electromagnetic vacuum hot water boiler. Background Technology

[0002] Vacuum hot water boilers maintain a high vacuum within a sealed furnace, causing the internal heat transfer medium water to boil and evaporate at low temperatures. The resulting steam exchanges heat with the system water in the internal heat exchange tubes, condenses, and then falls back into the heat transfer medium water chamber for circulation. This phase change heat transfer principle makes its thermal efficiency significantly better than that of conventional boilers. Its core advantage lies in its inherent safety, as the furnace is always under negative pressure, eliminating the risk of expansion and explosion. At the same time, the system water and heat transfer medium are completely isolated, preventing internal scaling and extending its lifespan. Because of its combination of high efficiency and safety, it is widely used in building heating and domestic hot water supply. Existing vacuum hot water boilers typically employ a heating method that involves direct contact between the electric heating element and the hot water medium. This heating method is prone to corrosion and breakdown, resulting in short equipment lifespan, rapid decline in thermal efficiency, and the risk of electric leakage. Therefore, we propose a novel electromagnetic vacuum hot water boiler. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an electromagnetic vacuum hot water boiler, which solves the problems of corrosion and breakdown that easily occur in existing heating methods, resulting in short device lifespan and the risk of electric leakage.

[0005] Preferably, the transmission assembly includes a rotating rod rotatably connected to the top of the vacuum chamber, with one end of the rotating rod extending into the interior of the vacuum chamber. A sealing element is provided on the outer wall of the rotating rod, and the sealing element is fixedly connected to the top of the vacuum chamber.

[0006] Preferably, a motor is fixedly connected to the top of the vacuum chamber, and the output end of the motor is fixedly connected to the end of the rotating rod located outside the vacuum chamber.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides an electromagnetic vacuum hot water boiler, which has the following beneficial effects: This utility model achieves efficient and rapid heating by setting an electromagnetic heating coil, significantly reducing energy consumption. Water and electricity are completely separated. The electromagnetic coil is outside the boiler and does not come into contact with water, fundamentally eliminating the risk of leakage. At the same time, the vacuum boiler itself operates under negative pressure, below the boiling point of normal pressure, with no risk of explosion, providing double safety protection. Meanwhile, the transmission components driven by the motor rotate the impact plate, which can effectively and promptly remove condensate droplets adhering to the isolation layer, preventing them from accumulating and forming a heat insulation layer. This ensures continuous and efficient heat exchange between the steam and the heat exchange tubes, enabling the boiler to operate stably at its optimal thermal efficiency for a long time. In addition, the reliable cooperation between the seal and the silicone ring maintains a vacuum environment, ensuring the safety and stability of the boiler operation. Attached Figure Description

[0015] This utility model provides a technical solution: Please see Figures 1-4 The electromagnetic vacuum hot water boiler includes a boiler frame 1, which provides a stable support structure for the entire boiler. An insulation shell 2 is installed on the boiler frame 1 to reduce heat loss, improve energy efficiency, and prevent external burns. A vacuum chamber 3 is installed inside the insulation shell 2, providing a sealed negative pressure environment as the core of the phase change heat transfer cycle of water evaporation and steam condensation. An insulation layer 4 is installed on the outer wall of the vacuum chamber 3 for electrical isolation, ensuring efficient transfer of magnetic field energy and preventing short circuits. An electromagnetic heating coil 5 is installed between the insulation shell 2 and the insulation layer 4. Its core function is to generate a high-frequency alternating magnetic field, causing eddy currents to form on the metal wall of the vacuum chamber 3, thus generating heat and providing a highly efficient heat source for the system. A transmission assembly 6 is installed on the top of the vacuum chamber 3.

[0016] Furthermore, the transmission assembly 6 includes a rotating rod 61, which is used to transmit rotational power. The rotating rod 61 is rotatably connected to the top of the vacuum chamber 3, and one end of the rotating rod 61 extends into the interior of the vacuum chamber 3. A sealing element 7 is provided on the outer wall of the rotating rod 61, which is used to maintain the airtightness of the vacuum chamber 3. The sealing element 7 is fixedly connected to the top of the vacuum chamber 3.

[0017] Furthermore, a motor 63 is fixedly connected to the top of the vacuum chamber 3, which provides the rotational power required to remove condensate. The output end of the motor 63 is fixedly connected to the end of the rotating rod 61 located outside the vacuum chamber 3.

[0018] Furthermore, multiple connecting rods 62 are fixedly connected to the outer wall of the rotating rod 61, which can fix and connect the striking plate 8. The other end of each of the multiple connecting rods 62 is fixedly connected to the striking plate 8. Its core function is to rotate with the rotating rod 61 and remove the condensate droplets attached to the isolation layer 9 by striking, so as to prevent the water droplets from accumulating and forming a heat insulation layer, thereby ensuring heat exchange efficiency.

[0019] Furthermore, an isolation layer 9 is fixedly connected to the top of the inner wall of the vacuum chamber 3. Its function is to guide the steam and serve as a surface for condensate droplets to adhere to and be removed. A collection funnel 10 is also fixedly connected to the inner wall of the vacuum chamber 3. Its function is to collect the knocked-down condensate and guide it back to the bottom of the vacuum chamber 3 to re-enter the circulation. A heat exchange tube 11 is provided between the isolation layer 9 and the wall of the vacuum chamber 3. Its core function is to allow the domestic water inside the tube to exchange heat efficiently with the steam outside the tube, thereby producing hot water. The heat exchange tube 11 is fixedly connected to the inner wall of the vacuum chamber 3.

[0020] It should be noted that the outer wall of the isolation layer 9 is provided with multiple holes. The water vapor generated by the heating medium water can come into contact with the heat exchange tube 11 through the multiple holes. After the heat exchange is completed, the water vapor forms condensate droplets on the side wall of the isolation layer 9 and the heat exchange tube 11. At this time, the motor 63 is started, which drives the striking plate 8 to strike the isolation layer 9 to clean the condensate droplets on the isolation layer 9. Since the isolation layer 9 and the heat exchange tube 11 are both fixedly connected to the inside of the vacuum chamber 3, the striking plate 8 will also cause the heat exchange tube 11 to vibrate slightly when it strikes the isolation layer 9, so that the condensate droplets formed on the surface of the heat exchange tube 11 will also slide off.

[0021] Furthermore, one end of the heat exchange tube 11 extends to the top of the vacuum chamber 3 and is fixedly connected to an inlet 111, which is used to introduce cold water to be heated. The other end of the heat exchange tube 11 extends to the outside of the vacuum chamber 3 and is fixedly connected to an outlet 112, which is used to output heated hot water.

[0022] Furthermore, a silicone ring 71 is provided on the inner wall of the seal 7, which enhances the dynamic sealing effect between the rotating rod 61 and the seal 7, ensuring the long-term stability of the vacuum environment. The outer wall of the rotating rod 61 is tightly fitted with the inner wall of the seal 7.

[0023] In practical use, the working principle of this utility model is as follows: Before the boiler is started, its vacuum chamber 3 has been evacuated and filled with a small amount of pure water as a heat medium. When it is working, the electromagnetic heating coil 5 wrapped around the outside of the vacuum chamber 3 is energized to generate a high-frequency alternating magnetic field, which causes the metal wall of the vacuum chamber 3 to generate eddy currents and heat up. The heat is transferred to the heat medium water at the bottom through the cavity wall.

[0024] In a vacuum environment, the boiling point of water is significantly reduced, so the heat transfer medium water can evaporate rapidly at low temperature to produce low-temperature steam. This steam rises in the vacuum chamber 3 and encounters the heat exchange tube 11 located at the top. At this time, the domestic water that needs to be heated is flowing in the heat exchange tube 11. When the steam comes into contact with the cooler wall of the heat exchange tube 11, it will condense into water droplets and release a large amount of latent heat of vaporization. This part of the heat is efficiently transferred to the domestic water in the tube, thereby providing hot water for users.

[0025] During this process, some water droplets formed by the condensation of steam will form on the isolation layer 9. If the water droplets accumulate, they will have an insulating effect, hindering the contact between steam and heat exchange tube 11 and reducing heat transfer efficiency. To solve this problem, the boiler is equipped with a transmission assembly 6 driven by a motor 63. The motor 63 drives the rotating rod 61 to rotate, and the striking plate 8 fixed on the rotating rod 61 rotates accordingly, periodically striking or scraping the surface of the isolation layer 9 to knock off the condensed water droplets. The knocked-off water droplets fall into the collection funnel 10 and flow back to the bottom of the vacuum chamber 3 along the funnel, where they are reheated and evaporated, completing a closed and efficient thermal cycle. Throughout the process, the sealing element 7 and the silicone ring 71 ensure the sealing of the rotating rod 61 when it passes through the top of the vacuum chamber 3, maintaining the internal vacuum environment.

[0026] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
