[0002] In response to the needs of social development, the water in household pipes is now considered drinking water. However, some drinking water pipes are located outdoors, especially in the north. In winter, the outdoor temperature is low, and the outdoor pipes of drinking water are prone to freezing, which can paralyze the entire drinking water system and prevent water from being supplied to residents.

However, water supply pipes are mostly located outdoors, and prolonged exposure to sunlight, rain, hail, and other severe weather can damage the insulation material, rendering it ineffective in insulating the pipe and increasing the risk of water supply system failure.

[0024] like Figure 1 As shown, the direct drinking water pipeline antifreeze and heat preservation system includes a water tank 100, a heat exchanger 220, and branch water pipes. The outlet end of the water tank 100 is connected to the inlet end of the heat exchanger 220 to form a first branch 121. The outlet end of the heat exchanger 220 is connected to the inlet end of the water tank 100 to form a second branch 122. The branch water pipes are connected to the second branch 122. The branch water pipes are suitable for connecting to the end of use. The inlet and outlet ends of the branch water pipes are both connected to the second branch 130. The inlet end of the branch water pipe is located at the front end of the outlet end of the branch water pipe. The branch water pipes and the second branch 122 form a loop.

[0025] The system includes a water tank 100 for providing a water source, a heat exchanger 220 for heating the drinking water, and branch pipes for delivering the drinking water to the user. The outlet of the water tank 100 is connected to the inlet of the heat exchanger 220, forming a first branch 121. The outlet of the heat exchanger 220 is also connected to the inlet of the water tank 100, forming a second branch 122. The first and second branches together form branch 120, from which the drinking water flows. 2. The branch water pipe is connected to the second branch 122. Drinking water flows from the second branch 122 into the branch water pipe, forming a complete pipeline. The branch water pipe is suitable for connecting to the user end. The inlet end 140 and outlet end 150 of the branch water pipe are both connected to the second branch 122, and the inlet end of the branch water pipe is set at the front end of the outlet end of the branch water pipe. The branch water pipe and the second branch 122 form a loop. This setting makes the pipeline circulate, so that the drinking water flows continuously.

[0026] In one possible implementation, a first thermometer 211 is installed on the first branch 121, located near the water inlet of the heat exchanger 220, and electrically connected to the heat exchanger 220.

The heat exchanger 220 includes a temperature sensing module 221 and a heating module 222. The temperature sensing module 221 and the heating module 222 are electrically connected. The first thermometer 211 is electrically connected to the temperature sensing module 221, and the second thermometer 212 is electrically connected to the temperature sensing module 221.

[0027] Specifically, such as Figure 1As shown, in order to determine whether the temperature of the drinking water is too low, a thermometer 210 is installed. A first thermometer 211 is installed on the first branch 121, and a second thermometer 212 is installed on the second branch 122. Both thermometers are electrically connected to the heat exchanger 220. The first thermometer 211 measures the temperature of the drinking water flowing out of the water tank 100, and the second thermometer 212 measures the temperature of the water returning to the water tank 100. When the temperature of the drinking water is lower than the set value, the heat exchanger 220 heats the water. When the temperature of the drinking water is heated to the set value, the heat exchanger 220 stops heating the water.

[0028] In one possible implementation, a pressure pump 160 is provided on the first branch 121, and the pressure pump 160 is located between the first thermometer 211 and the water tank 100.

[0029] Specifically, such as Figure 1 As shown, in order to enable drinking water to flow in the pipeline, a pressure pump 160 is installed between the first thermometer 211 and the water tank 100 to pressurize the drinking water.

[0032] In one possible implementation, two switch valves 170 are installed on the branch water pipe, one near the inlet end of the branch water pipe and the other near the outlet end of the branch water pipe; the switch valves 170 are installed to control the flow of drinking water from the branch water pipe to the user end.

[0033] In one possible implementation, the heat exchanger 220 is further provided with a 5G module and a switch module, with the 5G module and the switch module being electrically connected; the 5G module is electrically connected to the temperature sensing module 221, the switch module is electrically connected to the temperature sensing module 221, and the switch module is electrically connected to the heating module 222.

[0034] Specifically, the 5G module is set up to enable remote control of the heat exchanger 220, and the switch module is set up to work with the 5G module to enable remote control of the heater 220's switching on and off.

[0035] This application includes a water tank 100, a heat exchanger 220, and branch water pipes. The water tank 100 provides a water source, the heat exchanger 220 heats the drinking water, and the branch water pipes deliver the drinking water to the user. The outlet of the water tank 100 is connected to the inlet of the heat exchanger 220, forming a first branch 121. The outlet of the heat exchanger 220 is connected to the inlet of the water tank 100, forming a second branch 122. Drinking water flows from the first branch 121 to the second branch 122. The branch water pipes are connected to the second branch 122, and drinking water flows from the second branch 122 into the branch water pipes. This configuration forms a complete pipeline system. The branch water pipe is suitable for connecting to the user end. The inlet end 140 and outlet end 150 of the branch water pipe are both connected to the second branch 122. The branch 130 is formed by the outlet end 150 of the branch water pipe and the inlet end of the water tank 100. The inlet end 140 of the branch water pipe is set at the front end of the outlet end of the branch water pipe 150. The branch water pipe and the second branch 122 form a loop. This setting makes the pipeline form a circulation, so that the drinking water is always flowing. With the above settings, the drinking water is heated when the temperature is lower than the set value and the heating of the drinking water is stopped when the temperature is higher than the set value, so as to avoid the paralysis of the drinking water system caused by the freezing of the drinking water pipe.
