[0024] When in use, the above structure allows the water entering from the inlet to enter the filter sleeve 23, be filtered through the filter layer 24, and then be discharged from the outlet of the main housing 21. After a certain period of use, the cover plate 25 can be opened to remove the filter sleeve 23 for cleaning or replacement of the filter layer 24, which is very convenient.

[0025] Furthermore, the first heat exchange chamber 1 is provided with a spirally wound liquid guide plate 6.

The outer end of the overflow pipe 7 extends out of the outer side wall of the side plate of the hot water tank 10. When the water level is too high, the outlet end of the overflow pipe 7 directly discharges the water. It can be connected to a connecting pipe to transport the overflow water to a transition storage tank or other components for subsequent reuse. The transition storage tank or other components are all existing conventional structures and will not be described in detail here.

[0027] The inner tank 18 is fitted with an intermediate heat exchange tube 50 in the middle. The bottom end of the intermediate heat exchange tube 50 is welded and fixed to the middle of the top surface of the bottom plate of the hot water tank 10. The top of the intermediate heat exchange tube 50 extends out of the inspection through hole 19 formed in the middle of the top plate of the hot water tank 10. A sleeve part 191 is fixed to the top surface of the top plate of the hot water tank 10 around the inspection through hole 19. The top end of the sleeve part 191 is fixedly connected to the main cover 192 by bolts. The main cover 192 covers the top end of the sleeve part 191. A sealing ring is clamped between the top end of the main cover 192 and the top end of the sleeve part 191.

[0028] The top of the intermediate heat exchange tube 50 is inserted into the lower sleeve 193 fixed in the middle of the bottom surface of the main cover 192. A side sealing ring is nested in the annular groove of the inner side wall of the lower sleeve 193, and the inner side wall of the side sealing ring presses against the upper outer side wall of the intermediate heat exchange tube 50.

The guide holes in each pair of adjacent partition plates 51 are staggered; that is, the guide hole of one partition plate 15 is on the left end, and the guide holes of the adjacent partition plates 15 are on the right end.

[0030] An upper intermediate connecting pipe 8 is connected to the upper inner side of the inner tank 18, and a lower intermediate connecting pipe 9 is connected to the lower inner side wall of the inner tank 18. The inner ends of the upper intermediate connecting pipe 8 and the lower intermediate connecting pipe 9 are connected to the intermediate heat exchange tube body 50.

[0031] A liquid level sensor 100 is fixed on the top plate of the hot water tank 10, and the sensing end of the liquid level sensor 100 is located in the inner tank 18. A second temperature sensor 101 is fixed on the top plate of the hot water tank 10, and the sensing end of the second temperature sensor 101 extends into the inner tank 18.

[0032] In this embodiment, the returned hot water flows into the inner tank 18. At the same time, the heating steam is discharged from the steam boiler (which is a known device installed in the existing factory area and will not be described in detail) and enters the first heat exchange chamber 1. It can exchange heat with the returned hot water and make it heat up quickly. Since the returned hot water itself has a certain temperature, its heating rate is greatly improved. This process allows the heat energy of the returned hot water to be reused, improving the heat energy utilization rate. The reuse of the returned hot water reduces water discharge and has a good water-saving effect.

[0033] Meanwhile, the liquid level sensor 100 constantly senses the water level in the inner tank 18 (all electrical components used in this embodiment are electrically connected to the control host via electrical connection lines, and the operation is controlled by the control host). When the water level is lower than the set value, the control host controls the solenoid valve at the water inlet pipe connected to the water replenishment connection pipe 3 to open, so that water can enter the concave inner tank 18 for water replenishment.

[0034] In this embodiment, the steam enters the first heat exchange chamber 1 and the intermediate heat exchange tube 50 to exchange heat with the water in the inner tank 18. The heat exchange contact area is large and the heat exchange effect is good.

[0035] After heat exchange, the water is discharged from the outlet connection pipe 4. After being filtered by the water filter 20, it is discharged from the outlet pipe connected to the outlet of the delivery pump 30 for utilization. The first temperature sensor 5 can sense the temperature of the discharged water. When the temperature does not reach the required temperature, the solenoid valve at the outlet pipe connected to the outlet of the delivery pump 30 is closed.

[0036] Similarly, the second temperature sensor 101 can sense the temperature inside the inner tank 18 to monitor its operation at all times.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
