[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] like Figure 1 The water supply device provided in this application includes a water pipe 100, a heat exchange component 200, and a control component. The water pipe 100 is provided with an inlet end 11 for drinking water to flow in and an outlet end 12 for drinking water to flow out. The water pipe 100 also forms a sterilization water path for supplying sterilization water. During sterilization, the sterilization water flows along the sterilization water path inside the water pipe 100. The heat exchange component 200 is connected between the inlet end 11 and the outlet end 12 to heat the sterilization water. As the sterilization water flows along the sterilization water path, the heat exchange component 200 heats the sterilization water, causing its temperature to reach a predetermined sterilization temperature. The control component is connected to the heat exchange component 200 to control the heat exchange component 200 to heat the sterilization water to a set temperature range, which is the aforementioned sterilization temperature. The above methods can be used to sterilize the pipes inside the water supply device after it has not been used for a long time, thereby ensuring the health of drinking water.

[0030] The technical details of each component will be introduced below.

[0031] In some implementations, such as Figure 1 As shown, the heat exchange assembly 200 includes a heat exchanger 22 and a heat storage tank 21. The heat storage tank 21 is connected to the heat exchanger 22 via a heat exchange pipe 24. The heat storage tank 21 can contain a heat exchange medium, which can circulate between the heat exchanger 22 and the heat storage tank 21 to provide heat to the heat exchanger 22. During the flow of the heat exchange medium inside the heat exchanger 22, it can exchange heat with other water bodies, thereby heating other water bodies. The heat exchanger 22 is connected between the inlet end 11 and the outlet end 12 via a heat exchange inlet pipe 25 and a heat exchange outlet pipe 26. The sterilization water circuit includes the heat exchange outlet pipe 26 and a pipeline flowing from the heat exchange outlet pipe 26 to the outlet end 12. With the above design, when the sterilizing water flows in the sterilizing water path, it can flow from the inlet end 11 into the heat exchanger 22 through the heat exchange inlet pipe 25 to exchange heat with the heat exchange medium to reach the sterilization temperature, and then flow into the water path pipe 100 through the heat exchange outlet pipe 26 and flow through the outlet end 12. Thus, the heat exchange outlet pipe 26 and the pipeline from the heat exchange outlet pipe 26 to the outlet end 12 can be sterilized to ensure drinking water health.

[0032] In some implementations, such as Figure 1 As shown, the heat exchange assembly 200 also includes a heater and a heat pump 23. The heater is connected to the heat storage tank 21 to heat the heat exchange medium, and the heat pump 23 is installed along the heat exchange pipe 24 to drive the heat exchange medium to circulate. The sterilization water circuit also includes at least the pipes of the heat exchange pipe 24. The heat exchange medium can reach the sterilization temperature under the heating of the heater. At this time, the heat exchange medium can form a sterilization water body. When the heat exchange medium flows along the heat exchange pipe 24, it can sterilize the pipes inside the heat exchange pipe 24 to ensure drinking water health.

[0033] In some implementations, such as Figure 1 As shown, the control component is connected to the heat pump 23. The control component is equipped with a temperature sensor to sense the temperature of the heated water flow in the heat exchanger 22. The control component controls the flow rate of the heat exchange medium via the heat pump 23, thereby controlling the heat exchange efficiency of the heat exchanger 22. The control component ensures that the sterilizing water reaches the sterilization temperature during heat exchange in the heat exchanger 22, guaranteeing the sterilization effect.

[0034] In some implementations, such as Figure 1 As shown, a water replenishment pipe 04 is provided between the water inlet 11 and the heat storage tank 21. The heat exchange outlet pipe 26 is connected to the water replenishment pipe 04, and the sterilization water circuit also includes at least the water replenishment pipe 04. Normally, the heat exchange medium is drinking water. During the circulation of the heat exchange medium between the heat exchanger 22 and the heat storage tank 21, some of it evaporates, resulting in a decrease in the amount of heat exchange medium. Therefore, by providing the water replenishment pipe 04, the heat storage tank 21 can be replenished with the heat exchange medium through the water replenishment pipe 04. Since the water replenishment pipe 04 is connected to the water pipe 100, if bacteria grow inside the water replenishment pipe 04, it will also have an adverse effect on the hygiene of the water pipe 100. Through the above design, the sterilization water can flow through the water replenishment pipe 04 to sterilize the water replenishment pipe 04, thereby avoiding the adverse effects of bacteria inside the water replenishment pipe 04 on the water pipe 100.

[0035] In addition to the effects mentioned above, it is understandable that when the sterilizing water flows through the water supply pipe 04 to sterilize the water supply pipe 04, the sterilizing water is in a high-temperature state. At this time, the sterilizing water can flow into the heat storage tank 21 through the water supply pipe 04 to become a heat exchange medium. This can utilize the heat of the sterilizing water and replenish the heat exchange medium inside the heat storage tank 21.

[0036] In some implementations, such as Figure 1As shown, the heat exchange outlet pipe 26 and the heat exchange inlet pipe 25 are connected by a water pipe 100. Water can flow sequentially from the inlet end 11 through the heat exchange inlet pipe 25, the heat exchanger 22, and the heat exchange outlet pipe 26. Then, it flows along the water pipe 100 through the inlet end 11 and re-enters the heat exchange inlet pipe 25 to form a circulation loop. The sterilization water circuit also includes at least this circulation loop. Through this design, after the sterilization water flows out of the instant hot water outlet pipe, it can flow along the water pipe 100 through the inlet end 11 and then into the heat exchange inlet pipe 25, sterilizing the pipe from the inlet end 11 to the heat exchanger 22 to ensure safe drinking water. A circulation pump is installed along the above-mentioned circulation pipeline. The circulation pump can drive the sterilization water to circulate along the circulation pipeline. During the circulation process, the sterilization water can be heated by the heat exchanger 22, so that the temperature of the sterilization water can be repeatedly replenished, further improving the sterilization effect on the pipeline.

[0037] In some implementations, such as Figure 1 As shown, the heat storage tank 21 is provided with a heat storage cavity, an inlet 211, and an outlet 212. The inlet 211 and the outlet 212 are respectively connected to the heat storage cavity, which is used to contain the heat exchange medium. Correspondingly, the heat exchanger 22 is provided with a medium channel 001 and a water flow channel 002 arranged at intervals. The two ends of the medium channel 001 are respectively connected to the inlet 211 and the outlet 212. The heat exchange medium flows out of the heat storage tank 21 through the outlet 212 and enters the medium channel 001 of the heat exchanger 22, then flows out from the other end of the medium channel 001 and flows back to the heat storage tank 21 through the inlet 211. During the sterilization process, the sterilizing water flows through the water flow channel 002 of the heat exchanger 22 and exchanges heat with the heat exchange medium in the medium channel 001 to raise the temperature to the sterilization temperature. The heat exchanger 22 uses the heat exchange medium stored in the heat exchange medium during the heat exchange process with the sterilizing water. Because the medium channel 001 and the water flow channel 002 are spaced apart, the heat exchange medium and the sterilizing water do not come into contact during the heat exchange process; only heat is exchanged. In practical use, compared to existing instantaneous heating methods, the heat storage tank 21 can store heat in advance through the heat exchange medium, thus eliminating the need for a high-power heating device and making it safer to use.

[0038] In some implementations, such as Figure 2 , Figure 3 , Figure 4As shown, the heat exchanger 22 includes a shell 221 and a partition 222. A heat exchange cavity 03 is formed inside the shell 221. The partition 222 is connected to the shell 221 and separates the heat exchange cavity 03 to form a water flow channel 002 and a medium channel 001. The partition 222 has a thin sheet structure and can be made of a thermally conductive metal material. This design allows the heat exchanger 22 to effectively transfer the heat of the heat exchange medium to other liquids such as sterilization water, improving the heating efficiency of the heat exchanger 22 for sterilization water and facilitating a rapid and thorough sterilization process.

[0039] In some implementations, such as Figure 2 , Figure 3 , Figure 4 As shown, the heat exchanger 22 is provided with multiple baffles 222, which are spaced apart and separate the heat exchange chamber 03 to form multiple water flow gaps 02 and multiple medium gaps 01. The water flow gaps 02 and medium gaps 01 are alternately stacked and not connected. Among them, the multiple water flow gaps 02 are interconnected to form water flow channels 002, and the multiple medium gaps 01 are interconnected to form medium channels 001. This design can greatly increase the heat exchange area between the medium channels 001 and the water flow channels 002 (the surface area of ​​the baffles 222 that separate the medium channels 001 and the water flow channels 002), thereby greatly improving the heat exchange efficiency of the heat exchanger 22. This allows the sterilizing water to reach the sterilization temperature more quickly and sterilize the internal pipes of the water supply device along the sterilization water path.

[0040] In some implementations, such as Figure 1 As shown, the water supply device provided in this application also includes a back-suction component 300 and a faucet 400. The faucet 400 is connected to the water outlet 12. The sterilization water path includes at least the water path inside the faucet 400 and the pipeline flowing from the water outlet 12 to the faucet 400. After sterilization, the sterilization water can be discharged through the faucet 400. Since the discharged water has a sterilization temperature, it can sterilize the water path inside the faucet 400 and the pipeline flowing from the water outlet 12 to the faucet 400 to ensure drinking water health.

[0041] The sterilized water can also be discharged through the back suction component 300. The discharged sterilized water can sterilize the pipes flowing from the water pipe 100 to the back suction component 300 and the pipes inside the back suction component 300 to ensure drinking water health.

[0042] Specifically, the aforementioned back-suction assembly 300 includes a back-suction pump 32, a back-suction pipe 31, and a waste discharge pipe 33. The back-suction pump 32 is connected to both the back-suction pipe 31 and the waste discharge pipe 33. The back-suction pipe 31 is connected to the water pipe 100. The sterilization water path also includes at least the pipes flowing from the water pipe 100 through the back-suction pump 32 and then to the waste discharge pipe 33. After the sterilization water is discharged through the back-suction assembly 300, under the action of the back-suction pump 32, the sterilization water in the water pipe 100 flows sequentially from the water pipe 100 through the back-suction pipe 31, the back-suction pump 32, and the waste discharge pipe 33, thereby sterilizing the internal pipes of the back-suction assembly 300 to ensure drinking water health.
