It is the control box of the medium frequency induction heating equipment, which is used to control the entire heating process. Medium frequency induction is a power supply technology based on the principle of electromagnetic induction heating. When the magnetic flux surrounded by the conductor loop changes, an induced potential will be generated in the loop. The conductor in the alternating magnetic field will also generate an induced potential under the action of electromagnetic induction, and an induced current will be formed in the conductor to overcome the resistance of the conductor itself and generate Joule heat. This heat is used to heat the conductor itself, causing it to heat up and melt, so as to achieve various thermal processing purposes.

A water pipe 8 is provided on one side of the water tank 7, and one side of the water pipe 8 extends outward. When the water pipe 8 moves to the edge position below the refrigeration shell 4, one end of the water pipe 8 extends upward and passes through the partition plate 2. One end of the water pipe 8 extends into the setting groove 41, and the water pipe 8 moves upward in the setting groove 41. The water pipe 8 extends to the top surface of the refrigeration shell 4 and extends in the setting groove 41 on the top surface of the refrigeration shell 4. Then the setting groove 41 on the side of the refrigeration shell 4 extends downward, passes through the partition plate 2 and is connected to the top surface of the water tank 7. A water pump 9 is provided at the bottom of the inner cavity of the cabinet 1, and the water pump 9 is located below the partition plate 2, and a water delivery pipe 8 is passed through the water pump 9.
