With the cooperation of the cooling holes 101, the heat dissipation efficiency of the furnace body 1 is improved to avoid damage to parts of the boiler due to excessive internal temperature when the boiler is working for a long time.

[0031] Furthermore, a programmer mainboard 11 and a variable frequency water-cooled power board 13 are fixedly installed on the surface of the water tank 10 respectively. The variable frequency water-cooled power board 13 is located below the programmer mainboard 11. A water flow switch 15 is fixedly connected to the water tank 10 located below the variable frequency water-cooled power board 13. The water flow switch 15 is fixedly connected to the leakage protector 14 through a plurality of connecting lines 16. A water injection pipe 17 is fixedly connected to the lower surface of the water tank 10. One end of the water injection pipe 17 is fixedly connected to the furnace body 1. The heating liner 7 is fixedly connected to the water tank 10 through a connecting pipe 18.

[0032] Furthermore, two installation grooves 102 are provided on the inner wall of the furnace body 1 located on the upper and lower sides of the PLC control mainboard 9 .

[0033] Furthermore, the moisture-proof mechanism 19 includes a moisture-proof shell 1901, which is arranged outside the PLC control main board 9. The moisture-proof shell 1901 is fixedly connected to the furnace body 1 through a mounting member 1903, and the mounting member 1903 is adapted to the mounting groove 102. A first movable groove 19011 is provided on the upper surface of the moisture-proof shell 1901, and second movable grooves 19012 are provided on both sides of the moisture-proof shell 1901. Desiccant 1902 is placed in the first movable groove 19011 and the second movable groove 19012.

[0034] In the present application, the PLC control mainboard 9 is effectively protected by the provision of the moisture-proof housing 1901 and the desiccant 1902, thereby preventing the PLC control mainboard 9 from being short-circuited, corroded, and other problems caused by the humid environment, thereby extending the service life of the PLC control mainboard 9 and improving the adaptability of the boiler to harsh environments.

[0035] The provision of the first movable groove 19011 and the second movable groove 19012 provides space for storing the desiccant 1902 , and also facilitates the replacement of the desiccant 1902 , thereby improving the moisture-proof effect.

[0036] Furthermore, the mounting member 1903 includes four connecting blocks 19033, and the four connecting blocks 19033 respectively correspond to the four mounting grooves 102. The connecting blocks 19033 are fixedly connected to the rear side of the moisture-proof housing 1901, and one end of each connecting block 19033 is fixedly connected to an arc-shaped elastic member 19034.

Under the action of the U-shaped clamping member 19032, the plurality of arc-shaped elastic members 19034 are squeezed and compressed. After being inserted into the mounting block 19031, under the action of the U-shaped clamping member 19032, the arc-shaped elastic members 19034 are clamped. When it is needed, When disassembling the moisture-proof shell 1901, you only need to slide the moisture-proof shell 1901 to the right. At this time, the arc-shaped elastic member 19034 slides toward the side away from the U-shaped clamping member 19032. When the arc-shaped elastic member 19034 slides to the other side of the mounting block 19031, the moisture-proof shell 1901 can be removed from the furnace body 1 to replace the desiccant 1902. The setting of the mounting member 1903 improves the efficiency of disassembly and installation of the moisture-proof shell 1901, facilitates the replacement of the desiccant 1902, and improves convenience.

[0038] The working principle of this utility model:

[0039] When in use, firstly, the desiccant 1902 is inserted into the first movable groove 19011 and the second movable groove 19012 respectively, and then the plurality of arc-shaped elastic members 19034 fixedly connected to the moisture-proof housing 1901 are respectively correspondingly inserted into each mounting block 19031, and under the action of the U-shaped clamping member 19032, the plurality of arc-shaped elastic members 19034 are squeezed and compressed, and after being inserted into the mounting block 19031, under the action of the U-shaped clamping member 19032, the arc-shaped elastic members 19034 are clamped, thereby completing the fixing of the moisture-proof housing 1901;

[0040] When the desiccant 1902 needs to be replaced, the moisture-proof housing 1901 only needs to be slid to the right, and the arc-shaped elastic member 19034 slides toward the side away from the U-shaped clamping member 19032. When the arc-shaped elastic member 19034 slides to the other side of the mounting block 19031, the moisture-proof housing 1901 can be removed from the furnace body 1 to replace the desiccant 1902, thereby improving the moisture-proof effect of the PLC control mainboard 9.

[0041] Finally, the furnace cover 2 is closed, and water is then injected into the water tank 10 through the water injection pipe 17. The boiler is then connected to an external power source. Under the action of the electromagnetic coil 8, the water is heated for use by the user. Driven by the cooling fan 6, the boiler is cooled to prevent damage to parts of the boiler due to excessive internal temperature when the boiler is working for a long time. The display screen 3 and the indicator light 4 are set to set and monitor the operating parameters and status of the boiler, so that the user can intuitively understand the operating status of the boiler.

[0042] To sum up: the intelligent control end of this combined electromagnetic frequency conversion boiler effectively protects the PLC control mainboard 9 through the setting of the moisture-proof shell 1901 and the desiccant 1902, avoids the PLC control mainboard 9 from short circuit, corrosion and other problems caused by the humid environment, extends the service life of the PLC control mainboard 9, and improves the adaptability of the boiler to harsh environments. Through the setting of the mounting part 1903, the efficiency of disassembly and installation of the moisture-proof shell 1901 is improved, and the desiccant 1902 is easily replaced, thereby improving convenience.
