[0002] In the process of HVAC water supply, the water temperature needs to be increased, so the HVAC water supply needs to be heated. In order to save energy, a high-temperature water heat pump unit is usually used to heat the HVAC water supply, and the heat exchanger in the high-temperature water heat pump unit is used to complete the heat exchange, so as to increase the temperature of the HVAC water supply. This scheme specifically relates to a water heating device for a high-temperature water heat pump unit; the existing water heating device for a high-temperature water heat pump unit uses heat exchange to increase the temperature of the HVAC water, but when the water temperature does not meet the standard after heat exchange, it is not convenient to continue heating to make the water temperature meet the standard. At the same time, the internal structure of the heat exchanger is complicated and it is not easy to clean. After long-term use, scale accumulates, which will affect the service life of the heat exchanger and the heat exchange effect. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 5 As shown, the water heating device for the high-temperature water heat pump unit includes a shell 1, pipe boxes 2 are fixedly installed on both sides of the shell 1, a circulating water outlet 3 is fixedly installed through the top of one of the pipe boxes 2, a circulating water inlet 10 is fixedly installed through the bottom of the other pipe box 2, a water supply inlet valve 4 is fixedly installed through the bottom of the shell 1 on one side, a cleaning component 5 is installed inside the shell 1 and through one side of one of the pipe boxes 2, a temperature raising tank 6 is fixedly installed above the shell 1, a through valve 9 is fixedly installed between the temperature raising tank 6 and the shell 1, a water supply outlet 7 is fixedly installed through the top of the temperature raising tank 6 on one side, a temperature sensor 8 is fixedly installed through the top of the temperature raising tank 6 in the middle, and electric heating pipes 11 are fixedly installed on both sides of the inside of the temperature raising tank 6.

[0021] The cleaning assembly 5 includes a screw rod 501, on both sides of which adapter shafts 502 are fixedly installed, and on one side of one of the adapter shafts 502, a motor 503 is fixedly installed, and the outer ring of the screw rod 501 is provided with a scraper 504, and a plurality of pipe holes 505 are opened on both sides of the scraper 504, and four limiting holes 506 are opened on both sides of the scraper 504 and located on the outer periphery of the screw rod 501. By setting the cleaning assembly 5, it is convenient to scrape off the scale on the inner wall of the shell 1 and the outside of the heat exchange tube 13.

[0022] Tube sheets 12 are fixedly installed on both sides of the shell 1, and a plurality of heat exchange tubes 13 are fixedly installed between the two tube sheets 12 and on both sides of the tube sheets 12, and the positions of the tube holes 505 and the heat exchange tubes 13 correspond to each other. The scraper 504 is sleeved with the heat exchange tubes 13, and high-temperature wastewater flows inside the heat exchange tubes 13 to achieve heat exchange.

[0023] Four limiting rods 14 are fixedly installed between the two tube sheets 12 and in the center. The limiting holes 506 correspond to the positions of the limiting rods 14. The scraper 504 is sleeved with the limiting rods 14. The limiting rods 14 are provided to limit the scraper 504 to prevent the scraper 504 from rotating synchronously when the screw rod 501 rotates.

[0024] The adapter shaft 502 is movably connected to the pipe box 2 via a dynamic seal.

[0025] The outer diameter of the scraper 504 is equal to the inner wall of the housing 1 . When the screw rod 501 rotates, the scraper 504 is driven to move, and the scale attached to the inner wall of the housing 1 is scraped off by the moving scraper 504 .

[0026] It should be noted that the utility model is a water heating device for a high-temperature water heat pump unit. When in use, the wastewater pipe is first connected to the circulating water inlet 10, and the water supply pipe is connected to the water supply inlet valve 4. The high-temperature wastewater enters the pipe box 2 through the circulating water inlet 10, and then flows into the heat exchange pipe 13. The HVAC water supply flows into the shell 1 through the water supply inlet valve 4. After heat exchange with the high-temperature wastewater in the heat exchange pipe 13, the HVAC water supply temperature rises and enters the temperature raising tank 6 through the through valve 9. The wastewater is cooled and flows out through the circulating water outlet 3.

[0027] When the HVAC water flows into the temperature raising tank 6, the temperature sensor 8 detects the temperature of the HVAC water. If the temperature meets the standard, it flows directly to the water supply area through the water supply outlet 7. If the temperature does not meet the standard, the electric heating pipe 11 starts to heat the HVAC water, raising the temperature to the standard temperature and then flows directly to the water supply area through the water supply outlet 7.

[0028] When the motor 503 is started, it drives the adapter shaft 502 and the screw rod 501 to rotate synchronously, and uses the limit rod 14 and the limit hole 506 to limit the scraper 504. The rotating screw rod 501 drives the scraper 504 to move. During the movement of the scraper 504, the scale attached to the outer wall of the heat exchange tube 13 and the inner wall of the shell 1 is scraped off, and then the scale flows out from the circulating water outlet 3 along with the waste water, which is convenient for cleaning the inner wall of the shell 1 and the outer wall of the heat exchange tube 13.
