A curved pipe 8 is fixedly connected to the upper surface of the heat conduction box 7. Both sides of the outer side of the curved pipe 8 are sleeved with fixing plates 13, and one end of the fixing plate 13 is fixedly connected to the inner wall of the recovery box 1 for easy installation and disassembly. A guide assembly 9 is provided on the inner surface of the curved pipe 8, and a guide hole 11 is provided on the upper surface of the guide assembly 9.

[0026] Working principle: When using this device, the water to be heated is transported from the water inlet pipe 2 to the inside of the recovery box 1, and then the high-temperature waste water is transported from the hot water pipe 4 to the inside of the curved pipe 8. The hot water passes through the curved pipe 8, and the curved pipe 8 is heated by the transmission of the high-temperature hot water, and then the cold water inside the recovery box 1 is heated. When the high-temperature hot water is blocked by the guide plate 12, the time for the high-temperature hot water to pass through the curved pipe 8 is prolonged, and the heating time of the curved pipe 8 is prolonged, so that the cold water is better heated.

Under the action of the waste heat component 6, the effect of energy recovery and reuse is achieved, avoiding waste of resources. The heated water is discharged from the outlet pipe 3, and the high-temperature waste water is discharged from the drain pipe 5.
