Specifically, the technical effect that the setting of the water outlet 11 close to the sewage draining exit 13 can realize is the same as the technical effect that the setting of the first water return 12 close to the sewage draining exit 13 can realize, and the details are not repeated here.

Therefore, the overflow port 111 can discharge the redundant water in the main tank 10 in time, and the cracking of the main tank 10 caused by the excessive water pressure in the main tank 10 is avoided.

In another embodiment of the present invention, as shown in fig. 2 to 4, the main box 10 is provided with a second water return port 14 for connecting with a heating system or a cooling system. A second water return nozzle 141 is arranged at the second water return port 14. The second water return port 14, the water supply nozzle 24, and the heating system or the cooling system together form a second water circulation loop. Specifically, by arranging the second water return port 14 and enabling the second water return port 14, the water supply nozzle 24 and the water utilization equipment to jointly form a second water circulation loop, the water liquid flowing into the water utilization equipment from the water supply nozzle 24 can flow out of the water utilization equipment and then flows into the main tank 10 through the second water return port 14, and therefore the recycling of the water liquid with the waste heat of the water utilization equipment is achieved.

Therefore, the blind pipe 18 can be prevented from being influenced by the water flow at the first return port 12 or the water outlet 11, and the accuracy of measuring the water temperature in the main box body 10 can be improved.

Further, the vertical distance between the blind pipe 18 and the bottom of the main tank is more than 1.5 times of the vertical distance between the first return port 12 and the bottom of the main tank 10, and the length of the blind pipe extending into the main tank 10 is at least greater than one fifth of the inner diameter (or equivalent inner diameter) of the main tank 10, so as to accurately detect the temperature of the water in the main tank 10.

Furthermore, another blind pipe 18 or other plug-in unit can be additionally arranged above the blind pipe 18, and a temperature detector 19 is arranged on the other blind pipe 18 or plug-in unit for detecting the water temperature at the upper part in the main box body 10, so that the comprehensive and objective measurement of the water temperature in the main box body 10 is realized.

Further, for accurately detecting the water temperature, it is preferable that the blind pipe 18 and the center of the first water return opening 12 are not on the same vertical line, but are arranged in a staggered manner, so as to prevent the unstable water flow at the first water return opening 12 from causing the unbalanced water temperature and affecting the detection accuracy. Similarly, the centers of the blind pipe 18 and the second adapter pipe 22 are not on the same vertical line, so as to avoid the detection result error caused by the unbalanced water temperature at the matching port 211.

In other embodiments, if the temperature of the hot water or the cold water supplied from the main tank 10 to the water consumption device needs to be detected, the blind pipe 18 and the temperature detector 19 may be disposed at the matching port 211 corresponding to the first connection pipe 21 and the matching port 211 corresponding to the second connection pipe 22.

In another embodiment of the present invention, as shown in fig. 2 to 4, the blind pipe 18 is lower than the second connection pipe 22 in a direction perpendicular to the bottom surface of the main tank. Specifically, the height of the blind pipe 18 is lower than that of the second connecting pipe 22, so that the blind pipe 18 can measure the water temperature of the second water zone in the main tank 10, and further, the water temperature output to the external refrigeration system can be effectively monitored.

In another embodiment of the present invention, as shown in fig. 2 to 4, the first connection pipe 21 is located at a height of one-third to two-thirds of the main body 10 in a direction perpendicular to the bottom surface of the main body 10. Specifically, the first connection pipe 21 is disposed at a height of one-third to two-thirds of the main tank 10, so that the first connection pipe 21 is just located at a lower middle position of the first water area in the main tank 10, and thus, most of the water in the first water area can flow to an external heating system through the first connection pipe 21, and waste of the water liquid in the first water area is avoided.

In another embodiment of the present invention, as shown in fig. 2 to 4, the first connection pipe 21 is located at a half height of the main casing 10 in a direction perpendicular to the bottom surface of the main casing 10. Specifically, the first connection pipe 21 may be located at a half height of the main tank 10, so that the first connection pipe 21 may correspond to an upper middle position of the first water area of the main tank 10, thereby collecting water with a relatively high water temperature in the first water area, and further enabling the first connection pipe 21 to continuously provide hot water with a more appropriate water temperature to an external heating system through the water supply nozzle 24.
