Technical Field

[0002] An electric boiler is a device that uses electrical energy for heating, usually for heating or water heating. Compared with traditional gas or oil boilers, it does not require a fuel supply system, so it is cleaner and more environmentally friendly. The working principle of an electric boiler is to use a resistance heating element (usually a high-efficiency heating tube) to convert electrical energy into thermal energy to heat water or other media to the required temperature. In order to convert less electrical energy into useless heat and more energy into the heating medium, and improve energy efficiency, it is necessary to use a high-efficiency heating tube to heat the electric boiler.

[0003] In the use of traditional electric boilers, a first boiler, a second boiler and a connecting pipe are arranged, and water is put into the second boiler through the water inlet pipe. When the water level reaches the connecting pipe and flows into the first boiler through it, the power supply is connected to make the electric heating wire generate heat, so that the first heating pipe and the second heating pipe are heated, and the water in the first boiler and the second boiler is heated. Then, by starting the additional pump, the hot water flows back to the second boiler through the heating pipe. The water temperature of the return water drops and merges with the hot water in the second boiler and then flows into the first boiler, which can effectively reduce resource consumption and realize uninterrupted heating cycle.

[0004] However, the heating tubes of traditional electric boilers do not have a heat-conducting and heat-insulating structure, resulting in a certain gap between the heating tubes and the boiler, which greatly reduces the efficiency of heat conduction and causes a large amount of heat loss, resulting in more energy consumption when the water in the boiler needs to be boiled, affecting the energy efficiency of the electric boiler.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Specifically, in order to ensure the stability and safety of the electric heating tube 6, this design not only enables the electric heating tube 6 to be accurately embedded in a fixed position, but also limits it through the card slot 9, thereby avoiding the electric heating tube 6 from shaking or falling off during the heating process. The top of the heat-conducting frame 4 is firmly fixed to the bottom of the boiler body 1, forming a stable support structure. This design not only enhances the stability of the boiler as a whole, but also provides a uniform heating environment for the electric heating tube 6. The heat conduction between the boiler body 1 and the electric heating tube 6 is achieved through the heat conduction plate 15. This heat conduction plate 15 is made of ceramic fiber material and has good thermal conductivity. When the electric heating tube 6 starts to heat, the heat conduction plate 15 can quickly transfer heat to the water source in the boiler body 1, thereby achieving an efficient heating effect. It is worth noting that the groove 2 16 on the heat conduction plate 15 can fit tightly with the outer wall of the electric heating tube 6. This design not only greatly reduces the gap between the electric heating tube 6 and the boiler body 1, improves the transfer efficiency of heat energy, but also facilitates the disassembly and maintenance of the electric heating tube 6. In actual use, this design can significantly extend the service life of the electric heating tube 6 and reduce energy waste caused by heat loss. During the water boiling process, the water source is guided into the interior of the boiler body 1 through the water inlet pipe 2. Subsequently, the controller 5 starts to control the heating of the electric heating tube 6. Under the precise control of the controller 5, the electric heating tube 6 begins to release heat and continuously heats the water source in the boiler body 1. This heating method is not only fast and efficient, but also ensures that the water source is evenly heated, avoiding the phenomenon of local overheating or overcooling. In order to ensure the stability and safety of the electric heating tube 6 during operation, the base 7 is installed on the outer wall of the heat conducting frame 4. The base 7 not only provides additional support for the electric heating tube 6, but also plays a role in protection and heat preservation. During the heating process, the base 7 can reduce the heat exchange between the electric heating tube 6 and the external environment, thereby ensuring that the heat energy is mainly used to heat the water source in the boiler body 1.

[0034] Reference Figure 4 and Figure 5 The base 7 is provided with a heat preservation plate 8 inside, a groove 14 is provided inside the heat preservation plate 8, the electric heating pipe 6 is embedded in the groove 14, the base 7 is composed of a receiving layer 11, a heat preservation layer 12 and a protective layer 13, the outer wall of the receiving layer 11 is fixedly connected to the heat preservation layer 12, the outer wall of the heat preservation layer 12 is fixedly connected to the protective layer 13, and the size and shape of the groove 16 and the groove 14 are consistent with the size and shape of the heat conduction frame 4;

[0035] Specifically, first, the insulation board 8 is made of rock wool, which is a high-temperature insulating material with basalt as the main raw material. Rock wool has excellent high temperature resistance and excellent thermal insulation performance. The rock wool insulation board 8 is set in the base 7 of the boiler body 1, which can effectively prevent the loss of heat and ensure that the heat of the boiler body 1 is effectively utilized during operation. The thermal insulation structure of the boiler body 1 and the base 7. These two parts are combined by the receiving layer 11, the thermal insulation layer 12 and the protective layer 13 to form a complete thermal insulation system. This design can minimize the loss of heat and improve the thermal efficiency of the boiler. The receiving layer 11 is made of stainless steel. This material not only has good high temperature resistance, but also can withstand greater pressure, providing a solid support for the thermal insulation layer 12. The thermal insulation layer 12 is made of silicone sponge. This material is not only resistant to high temperature, but also has good softness. It can fit closely to the surface of the boiler and effectively reduce heat loss. The protective layer 13 is made of glass fiber reinforced plastic, which has good corrosion resistance and weather resistance, can resist the erosion of the external environment, and protect the internal thermal insulation material from damage. At the same time, FRP also has higher strength, providing additional safety for the entire insulation structure.

[0036] Working principle: When using the high-efficiency heating tube of the electric boiler, first, the electric heating tube 6 is embedded in the slot 9 on the heat-conducting frame 4 through the guide groove 10 to fix the electric heating tube 6. At the same time, the top of the heat-conducting frame 4 is fixed to the bottom of the boiler body 1. The boiler body 1 and the electric heating tube 6 are heat-conducted through the heat-conducting plate 15. The heat-conducting plate 15 is made of ceramic fiber material and has good thermal conductivity. The groove 16 can be repeatedly fitted with the outer wall of the electric heating tube 6, which greatly reduces the gap between the electric heating tube 6 and the boiler body 1, and is also convenient for disassembly and maintenance of the electric heating tube 6. Then the base 7 can be installed on the outer wall of the heat-conducting frame 4 to protect and insulate the electric heating tube 6. When boiling water, the water source enters the boiler body 1 through the water inlet pipe 2. The controller 5 then controls the heating of the electric heating tube 6 to heat the water source in the boiler body 1. The insulation board 8 arranged in the base 7 can prevent the loss of heat and is made of rock wool. Rock wool is a high-temperature insulating material made of basalt as raw material, which has good high temperature resistance and thermal insulation performance. Then the boiler body 1 and the base 7 are combined by a receiving layer 11, an insulation layer 12 and a protective layer 13, which can insulate them to the greatest extent and prevent heat loss. The receiving layer 11 is made of stainless steel, and the insulation layer 12 is made of silicone sponge with good high temperature resistance and softness. The protective layer 13 is made of fiberglass, which has good corrosion resistance and weather resistance and can protect the internal materials.
