[0026] The present invention will now be described in further detail with reference to the accompanying drawings.
[0027] like Figure 1 The water supply device shown includes a water pipe 100 and a heat exchange component. The water pipe 100 includes an inlet end 11 and an outlet end 12, which are connected. The outlet end 12 is used to connect to a faucet 500. Drinking water can enter the water pipe 100 through the inlet end 11 and then be discharged from the faucet 500 through the outlet end 12. The water pipe 100 forms a sterilization water path for the flow of sterilization water. It should be noted that the sterilization water is drinking water that has been heated to a predetermined sterilization temperature. During sterilization, the sterilization water flows along the sterilization water path. At the sterilization temperature, the sterilization water can sterilize the pipe along the sterilization water path.
[0028] The heat exchange assembly has a container for holding the heat exchange medium. The heat exchange assembly can heat the heat exchange medium inside the container. In actual use, the heat exchange medium is drinking water. When the heat exchange medium is heated to the sterilization temperature, it can form sterilized water. A first pipe 01 connects the water pipe 100 and the container. The heat exchange medium inside the container can flow into the water pipe 100 through the first pipe 01 and flow along the sterilization water path. The drinking water in the water pipe 100 can also flow into the container through the first pipe 01 to become the heat exchange medium. The sterilization water path includes at least the first pipe 01 and the pipes flowing from the first pipe 01 to the outlet 12. Through the above design, the heat exchange medium is heated to the sterilization temperature to form sterilized water. The sterilized water flows into the water pipe 100 through the first pipe 01 to sterilize the first pipe 01 and the pipes flowing from the first pipe 01 to the outlet 12.
[0029] The technical details of each component will be introduced below.
[0030] In some implementations, such as Figure 1 As shown, the first pipe 01 is connected to the water pipe 100 through the first connecting part 13; the first connecting part 13 is located near the water inlet 11 along the water pipe 100. With the above design, after the sterilizing water enters the water pipe 100 through the first pipe 01, it can flow along the sterilizing water path through more parts of the water pipe 100, thereby sterilizing more parts of the water pipe 100 and improving the sterilization effect of the internal pipes of the water supply device.
[0031] In some implementations, such as Figure 1 As shown, the S-row heat exchange assembly includes a heat exchanger 200 and a heat storage tank 300. The heat exchanger 200 and the heat storage tank 300 are connected by a heat exchange pipe 02. The heat storage tank 300 is provided with a heat storage cavity for accommodating the heat exchange medium and an electric heating device for heating the heat exchange medium. In actual use, the heat exchange medium can circulate between the heat exchanger 200 and the heat storage tank 300 through the heat exchange pipe 02 to continuously transfer heat to the heat exchanger 200. It can be understood that in order to enable the heat exchange medium to circulate between the heat exchanger 200 and the heat storage tank 300, a heat pump is provided along the heat exchange pipe 02 to drive the circulation of the heat exchange medium.
[0032] The heat storage chamber is connected to the water pipe 100 through the first pipe 01. The heat exchange medium can flow out of the heat storage chamber through the first pipe 01, then enter the water pipe 100 and flow along the sterilization water path to sterilize the pipes along the sterilization water path.
[0033] In some implementations, such as Figure 1 As shown, a sterilization pump 03 is installed along the first pipeline 01. The sterilization pump 03 is used to drive the heat exchange medium into the water pipeline 100 or to drive drinking water into the heat storage tank 300.
[0034] During the sterilization process, the sterilization pump 03 can extract the heat exchange medium from the heat storage tank 300 and drive the heat exchange medium to flow along the sterilization water path to sterilize the pipeline inside the water supply device.
[0035] When the heat exchange medium inside the heat storage tank 300 needs to be replenished, the sterilization pump 03 can pump drinking water or heat exchange medium from the water pipe 100 into the heat storage tank 300 to replenish the heat exchange medium inside the heat storage tank 300, so as to avoid the heat exchange effect of the heat exchange components and the sterilization effect of the water supply device pipeline being affected by insufficient heat exchange medium in the heat storage tank 300.
[0036] In some implementations, such as Figure 1 As shown, the water supply device provided in this application also includes a faucet 500, which is connected to the water outlet 12; the sterilization water path includes at least a water path flowing from the water outlet 12 to the faucet 500 and a water path inside the faucet 500. Through the above design, the sterilization water formed by the heat exchange medium enters the water pipe 100 and flows through the water outlet 12 and is discharged through the faucet 500. Since the sterilization water discharged through the faucet 500 has a sterilization temperature, it can sterilize the water path flowing from the water outlet 12 to the faucet 500 and the water path inside the faucet 500, thus making the sterilization range of the internal pipes of the water supply device more extensive.
[0037] In some embodiments, the water supply device provided in this application further includes a control component connected to an electric heating device for heating the heat exchange medium to the sterilization temperature. This ensures that the sterilizing water flowing along the sterilization water path reaches a sufficient temperature to sterilize the pipes along the sterilization water path, thus guaranteeing the sterilization effect of the sterilizing water.
[0038] In some embodiments, the control components include a temperature sensor and a control module. The control module is connected to the temperature sensor and the electric heating device. The temperature sensor is located in the heat storage tank 300 to sense the temperature of the heat exchange medium. In practical applications, the control module can use the temperature sensor to sense whether the heat exchange medium inside the heat storage tank 300 has reached the sterilization temperature, and then control whether the electric heating device continues to heat the heat exchange medium.
[0039] In some implementations, such as Figure 1 As shown, the control component includes multiple temperature sensors, which are arranged along the sterilization water path and are all connected to the control module.
[0040] In practical use, as the sterilizing water flows along the sterilization water path, its heat is absorbed by the pipes, causing the water temperature to decrease as it flows. This can lead to insufficient temperature in certain sections of the pipes, preventing effective sterilization. The above design, by installing multiple temperature sensors along the sterilization water path, can detect the temperature of the water as it flows through various parts of the pipes. If insufficient temperature is detected in a localized area, the control component can activate the heating element to raise the temperature of the heat exchange medium, ensuring that the resulting sterilizing water is sufficiently warm to effectively sterilize all pipes along the sterilization water path.
[0041] The control module can also be connected to the sterilization pump 03. If the temperature of the sterilization water gradually decreases during the flow process, affecting the sterilization effect on the pipeline, the control module can increase the delivery of the heat exchange medium to ensure that the temperature of the sterilization water flowing through each part of the sterilization water path is sufficient to effectively sterilize the pipeline.
[0042] In addition to the above structure, the control component also includes a timing module. The timing module is connected to the control module and can preset a sterilization time. This allows the sterilization water to continue flowing for a predetermined time after reaching the sterilization temperature. Combined with the above measures to ensure the temperature of the sterilization water, the sterilization effect can be ensured by guaranteeing the temperature and duration of sterilization, further ensuring the sterilization effect of the internal pipes of the water supply device.
[0043] In some embodiments, the water supply device provided in this application further includes a back suction component 400, which is connected to the water pipe 100 and / or the first pipeline 01 via a first back suction pipe 41; the sterilization water path also includes at least a pipeline flowing from the water pipe 100 or the first pipeline 01 to the back suction component 400.
[0044] like Figure 1 As shown, the back-suction assembly 400 is connected to the water pipe 100 via the first back-suction pipe 41. In actual use, after the water supply device dispenses water, some undispensed water remains in the pipes inside the device. Over time, the quality of this residual water deteriorates, and bacteria may even grow, producing an odor. When water is dispensed next time, this residual water is preferentially discharged, negatively impacting the quality of the dispensed drinking water and potentially affecting the user's experience and even health. Through the above design, the back-suction assembly 400 can promptly remove the residual water from the water pipe 100 via the first back-suction pipe 41 to avoid affecting the quality of the next water dispensing. Timely removal of residual water also prevents bacterial growth, thus reducing bacteria inside the water supply device's pipes.
[0045] In addition to the above effects, after the water dispenser has sterilized, the back suction assembly 400 can also discharge the sterilized water in the water pipe 100. The back suction assembly 400 can also be connected to the first pipe 01 through the first back suction pipe 41 to draw out the residual heat exchange medium inside the first pipe 01, reducing water accumulation in the internal pipes of the water supply device; furthermore, when the back suction assembly 400 discharges the sterilized water from the water pipe 100 and the first pipe 01, the sterilized water can also sterilize the first back suction pipe 41 and the internal pipes of the back suction assembly 400 as it flows through them.
[0046] In some implementations, such as Figure 1 As shown, the back-suction assembly 400 can also be connected to the heat storage tank 300 via the second back-suction pipe 42; the sterilization water circuit also includes at least the pipeline flowing from the heat storage tank 300 to the back-suction assembly 400. In actual use, the water quality of the heat exchange medium inside the heat storage tank 300 may decrease after long-term storage and circulating heating, so it is necessary to replace the heat exchange medium inside the heat storage tank 300 regularly. Through the above design, the back-suction assembly 400 can discharge the heat exchange medium from the heat storage tank 300 via the second back-suction pipe 42 to replace the heat exchange medium inside the heat storage tank 300. During the discharge process of the heat exchange medium through the back-suction assembly 400, the heat exchange medium can sterilize the second back-suction pipe 42 and the pipeline inside the back-suction assembly 400.
