[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] like Figure 1-3 As shown, a PTC ceramic heating water heater unit includes a unit housing 1, an outlet pipe 2, and an inlet pipe 3. The outlet pipe 2 is connected to a magnetic descaling device 11, and the inlet pipe 3 is connected to a second water pump 14. A second pipe 7 is provided on one side of the second water pump 14, and a first pipe 6 is connected to the second pipe 7. The upper end of the first pipe 6 is connected to the magnetic descaling device 11, which is mounted on a support plate 13. The first pipe 6 is connected to a pressure display gauge 5. A PTC heating module 8 is provided on the second pipe 7, and the second pipe 7 is connected to a water storage tank 9, which is mounted on a support frame 12. A third pipe 10 is connected to the other side of the water storage tank 9, and the other end of the third pipe 10 is connected to the first water pump 4.
[0019] The first water pump 4 is equipped with a water inlet, and the third pipe 10 is equipped with a PTC heating module 8; the support plate 13 is set on the inner wall of the unit box 1, the pressure display gauge 5 is fixedly connected to the bottom of the unit box 1, and the support frame 12 is fixedly connected to the bottom of the unit box 1.
[0020] During operation, raw water enters the second water pump 14 from the inlet pipe 3. The water flows along the second pipe 7 through the PTC heating module 8 and is heated before entering the water storage tank 9. A small booster pump is installed in the water storage tank 9 to discharge the hot water into the magnetized descaling device 11. After being filtered by the magnetized descaling device 11, the water flows out through the outlet pipe 2. Raw water can directly enter the magnetized descaling device 11 through the first pipe 6, so that it can be mixed with the superheated water to become warm water.
[0021] To increase the flow rate of hot water, the first water pump 4 can be turned on. The raw water is heated by the PTC heating module 8 and enters the water storage tank 9 through the third pipe 10, thus increasing the total amount of hot water.
