[0029] The working principle and usage process of the present invention are as follows: the electric ball valves 28 of the water inlet pipe 26 and the water outlet pipe 27 are in the closed state, the heating unit 1 23, the heating unit 24, and the heating unit 3 25 are not powered, and the zigzag pipe group 21 and the coiled pipe group 22 are connected by the flange 1 31 to form a continuous water flow channel; First, the electric ball valve 28 is opened, and then the water inlet pipe 26 is opened. At this time, water flows into the water inlet pipe 26 and passes through the area surrounded by the heating unit 1 23. The heating unit 1 23 uses electromagnetic induction heating to preheat the water temperature. The preheated water flows into the zigzag pipe group 21. Its multi-bend structure can extend the water flow path. At this time, the heating unit 24 is activated to generate a high-frequency electromagnetic field, which preheats the water flow for a second time. The water after the secondary preheating flows into the coiled pipe group 22. The coiled structure can further extend the path. The heating unit 3 25 operates at maximum power to raise the water temperature to the set target value. The hot water is then transported to the industrial water point through the outlet pipe 27. The heating unit 1 23, the heating unit 24 and the heating unit 3 25 are all equipped with components such as a water level monitor and a dry burn prevention device. When the water level is lower than the set value, the system automatically stops the heating unit 1 23, the heating unit 24 and the heating unit 3 25. The heating unit 1 23, the heating unit 24, the heating unit 3 25, the water level monitor and the dry burn prevention device are mature existing technologies. For specific operations, please refer to the existing technologies. The heating unit 1 23 , the heating unit 24 , and the heating unit 3 25 are all configured by combining two plywood panels and are detachably connected by screws. The first housing body 1 and the second housing body 12 also use the same technology. When water flows into the water inlet pipe 26, the operator can open or close the electric ball valve 28 to control the inflow of water; When disassembling the pipe group, first loosen flange 1 31 to separate the zigzag pipe group 21 and the coiled pipe group 22, then loosen flange 2 32 to separate the inlet pipe 26 and the outlet pipe 27, and then take out any pipe group separately for maintenance. When installing a single unit, first rotate the support plate 43 so that the support plate 43 drives the movable rod 42 to rotate between the two connecting seats 41 to adapt to the installation requirements of the wall or the ground. At this time, the operator puts the second mounting block 45 on the wall and then rotates the bolt 46 so that the bolt 46 is threadedly connected to the preset hole opened in the wall, thereby completing the installation of the single unit. When installing multiple groups, first connect the water inlet pipes 26 and the water outlet pipes 27 of the multiple groups through the flange 2 32 so that the multiple groups are processed in parallel, and then place the whole on the floor stand 49. At this time, multiple bolts 46 are respectively threaded into the threaded holes opened on the surface of the first mounting block 44 and the second mounting block 45, and then tighten the bolts 46 so that the bolts 46 are threaded into the threaded holes opened on the surface of the floor stand 49, thereby realizing the installation of multiple groups.

[0030] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
