[0038] Working principle: First, the staff connects the cold water pipe with the cold water connection pipe 6, and connects the hot water pipe with the hot water connection pipe 7, so that the cold water pipe injects cold water into the shell 1. At the same time, the heat medium enters the heat exchange cylinder 2 from the heat medium pipe 5, and enters the heat exchange bundle tube 3, so that the heat exchange bundle tube 3 heats the cold water in the shell 1. The water flow in the shell 1 enters the inner side of the spiral scraper 15 along the outer side of the baffle 16, so that the water flow flows between the multiple baffles 16 and the spiral scraper 15, which is convenient for the heat exchange bundle tube 3 to fully heat the water flow. The heated water is discharged into the hot water delivery pipe through the hot water connection pipe 7, thereby improving the heat exchange efficiency;

[0039] When the inner side of the shell 1 needs to be cleaned, the staff starts the driving motor 13 and opens the drain valve 17, and injects water into the shell 1, so that the driving motor 13 drives the driving rod 11 to rotate, and the driving rod 11 drives the positioning ring 9 to rotate through the positioning frame 10, and the positioning ring 9 drives multiple installation rods 19 to make a circular motion with the driving rod 11 as the center, so that the installation rod 19 drives the slip ring 18, the spiral scraper 15 and the installation ring 14 to rotate synchronously, and the spiral scraper 15 moves along the inner side of the shell 1 to scrape off the scale and impurities inside the shell 1. At the same time, the installation rod 19 drives the plug 21 to move synchronously, and the plug 21 slides out of the slot on the fixed retaining ring 20, so that the plug 2 1 drives the mounting rod 19 to move, and the mounting rod 19 drives the mounting ring 14 to move synchronously, so that the mounting ring 14 compresses the spiral scraper 15 of the elastic material, and the mounting rod 19 pushes the sliding ring 18 to move along the sliding cavity of the shell 1 to compress the spring 33. When the plug block 21 is aligned with another slot, the spring 33 and the rebound force of the spiral scraper 15 are used to make the mounting rod 19 push the plug block 21 to be inserted into the slot again. Therefore, with the movement of the mounting rod 19, the mounting rod 19 is in a state of reciprocating left and right movement, realizing the repeated expansion and contraction of the spiral scraper 15, so that the spiral scraper 15 can scrape off the harder scale on the inner side of the shell 1, thereby improving the cleaning of scale and impurities. The spiral scraper 15 sends the sewage into the sewage valve 17, and the sewage enters the sewage box 22 through the sewage valve 17, so that the filter plate 24 on the installation frame 23 filters the sewage, and the scale and impurities stay on the filter plate 24. The filtered water enters the interior of the sewage box 22. At the same time, the driving rod 11 drives the driven rod 27 to rotate synchronously through the synchronous belt 29, so that the driven rod 27 drives the cam 28 to rotate. When the convex edge of the cam 28 contacts the bottom of the installation frame 23, the convex edge of the cam 28 is used to push one side of the installation frame 23 to swing upward, so that the installation frame 23 drives the filter plate 24 to tilt, and the positioning rods 25 on both sides of the installation frame 23 are against the coil spring 2 6 is compressed, and the sealing plate 34 on the mounting frame 23 is away from the drainage groove of the drainage box 22, so that the scale and impurities on the filter plate 24 can be discharged into the drainage frame 35 through the drainage groove. When the convex edge of the cam 28 is away from the mounting frame 23, the resilience of the coil spring 26 is utilized to reset the mounting frame 23. Thus, the mounting frame 23 is in an intermittent swinging state, so that the scale and impurities are automatically discharged. At the same time, the water inside the drainage box 22 can be returned to the housing 1 through the drainage pump 30, so as to facilitate the flushing of the inner side of the housing 1, realize the reuse of resources, and improve the drainage efficiency, thereby achieving the effect of comprehensive cleaning and rapid drainage, and ensuring the normal heat exchange of the heat exchange bundle tube 3 with the cold water.
