Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric boiler technology, specifically to an electric boiler with a double inner tank heating structure. Background Technology
[0002] Electric boilers are widely used in industries such as chemical, pharmaceutical, textile, food, and domestic water use. They can stably and efficiently provide hot water or steam to meet the needs of industrial production for different temperature and pressure conditions. Compared with traditional coal-fired boilers, electric boilers have no smoke emissions and do not produce pollutants, which meets modern environmental protection requirements.
[0003] Traditional electric boilers still have some shortcomings in their use:
[0004] 1. The heating speed is slow, making it difficult to quickly meet users' urgent needs for hot water or heating. The safety and stability are insufficient. Once the heating system malfunctions, the electric boiler will stop operating, seriously affecting the user's normal use.
[0005] 2. At the same time, the power is limited during use. Taking wall-mounted electric boilers as an example, their maximum power can usually only reach 20 kilowatts, which cannot meet the needs of some users with high heat demand, thus limiting the application scope of the product and user choices.

[0027] The boiler body 2 is equipped with a first heating tube 11 and a second heating tube 12, thus adopting a dual heating system and being equipped with two independent but coordinated heating systems.
[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first controller 4, the second controller 7, and the cable board 5 are fixedly connected to the side of the mounting plate 3. The cable board 5 is located at the bottom of the first controller 4 and the second controller 7. The first controller 4 and the second heating tube 12 are electrically connected through the second connecting line 16. The second controller 7 and the first heating tube 11 are electrically connected through the first connecting line 15. The top of the mounting cover 14 is fixedly connected to the water inlet pipe 13, which is connected to the boiler body 2. The bottom of the boiler body 2 and the mounting box 1 are respectively provided with discharge holes 17, which are connected to each other.
