[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1 A water supply device provided by the present application shown includes a water pipe 100, which is provided with a water inlet end 11 and a water outlet end 12. The water pipe 100 forms a sterilization water channel for sterilization water to flow. Drinking water can enter the water pipe 100 from the water inlet end 11 and then flow out of the water pipe 100 from the water outlet end 12; the water pipe 100 is also provided with a sterilization water supply interface for sterilization water to flow to the sterilization water channel. The sterilization water supply interface is arranged in the water pipe 100 between the water inlet end 11 and the water outlet end 12. Sterilization water can enter the sterilization water channel through the sterilization water supply interface and flow along the sterilization water channel, and then flow out of the water pipe 100 from the water outlet end 12; the sterilization water channel at least includes a pipeline from the sterilization water supply interface to the water outlet end 12.

[0026] It should be noted that the sterilization water body is used to sterilize the sterilization waterway. In actual use, it can be formed by heating drinking water. The sterilization water body has a sterilization temperature, and the pipes along the sterilization waterway are sterilized by high-temperature sterilization.

[0027] The following will introduce the technical details of each component one by one.

[0028] In some embodiments, Figure 1 As shown, the water supply device provided in the present application also includes a sterilization component for forming a sterilization water body, the sterilization component is connected between the water inlet end 11 and the water outlet end 12, and the sterilization water circuit at least includes a pipeline from the sterilization component to the water outlet end 12 or / and a pipeline from the water pipe 100 to the sterilization component.

[0029] In actual use, drinking water enters the water pipe 100 through the water inlet end 11 and flows through the sterilization component to form a sterilization water body. The sterilization component can heat the drinking water so that the temperature of the drinking water reaches the sterilization temperature. In this way, when the sterilization water body flows along the sterilization water path, the pipes contained in the above-mentioned sterilization water path can be sterilized, thereby ensuring the health and hygiene of the drinking water.

[0030] In some embodiments, the above-mentioned sterilization component includes a heat exchange component 200 and / or an instant heater 300, and the heat exchange component 200 and / or the instant heater 300 are connected to the water pipe 100 through a hot water outlet pipe, and the sterilization interface is the interface of the hot water outlet pipe.

[0031] It should be noted that the heat exchange component 200 heats the drinking water by heat exchange. Heat is stored inside the heat exchange component 200 through the heat exchange medium. During heating, the drinking water can be heated by simply transferring the heat stored inside the heat exchange medium to the drinking water. The heat exchange component 200 can store heat in advance.

[0032] like Figure 1 As shown, the above-mentioned sterilization component includes a heat exchange component 200 and an instant heater 300. Drinking water can flow to the heat exchange component 200 through the water inlet end 11, and then flow to the instant heater 300, and finally flow out from the hot water outlet pipe to enter the sterilization waterway. When flowing through the heat exchange component 200 and the instant heater 300, the drinking water can be heated to the sterilization temperature by the heat exchange component 200, and can also be heated to the sterilization temperature by the instant heater 300, and can also be heated to the sterilization temperature by the heat exchange component 200 and the instant heater 300.

[0033] Specifically, when the heat inside the heat exchange component 200 is sufficient, the heat exchange component 200 can directly heat the drinking water to the sterilization temperature to form a sterilizing water body; because the heat exchange component 200 uses its stored heat when exchanging heat, it is not necessary to generate heat through other electric heating devices when heating drinking water, which reduces the power of the water supply device during sterilization and makes it safer to use. In addition, the heat exchange component 200 uses its own pre-stored heat to sterilize the pipes inside the water supply device when there is a power outage.

[0034] If the heat inside the heat exchange component 200 is insufficient, the drinking water cannot be directly heated to the sterilization temperature through the heat exchange component 200. At this time, the instant heater 300 can be used to supplement the drinking water to ensure that the drinking water can reach the sterilization temperature after flowing through the sterilization component, thereby ensuring the stability and effectiveness of the sterilization process.

[0035] In some embodiments, the water supply device provided by the present application is provided with a container, which can be used to accommodate the heat exchange medium, and a water replenishment pipeline 01 is connected between the container and the water pipe 100, and the sterilization water circuit at least includes a water replenishment pipeline 01, and the sterilization water can flow into the water replenishment pipeline 01 from the water pipe 100. In actual use, the heat exchange medium is usually drinking water. Since the heat exchange medium needs to store heat and needs to be in a high temperature state for a long time, part of the heat exchange medium will be evaporated, resulting in less heat exchange medium, so by providing a water replenishment pipeline 01, the heat storage tank 22 can replenish the heat exchange medium through the water pipe 100. Since the water supply pipeline 01 and the water pipe 100 are connected, if bacteria grow inside the water supply pipeline 01, it will also have an adverse effect on the hygiene of the water pipe 100. Through the above design, the sterilized water can flow through the water supply pipeline 01 to sterilize the water supply pipeline 01, thereby avoiding the bacteria inside the water supply pipeline 01 from having an adverse effect on the water pipe 100.

[0036] In addition to the above effects, it can be understood that when the sterilization water flows through the water replenishment pipeline 01 to sterilize the water replenishment pipeline 01, the sterilization water is in a high-temperature state. At this time, the sterilization water can flow into the heat storage tank 22 through the water replenishment pipeline 01 to become a heat exchange medium. On the one hand, the heat of the sterilization water can be utilized, and on the other hand, the heat exchange medium inside the heat storage tank 22 can be replenished.

[0037] In some embodiments, the heat exchange assembly 200 includes a heat exchanger 21 and a heat storage tank 22 . A water supply pipeline 01 is connected between the heat storage tank 22 and the water pipe 100 . The sterilization water circuit at least includes the water supply pipeline 01 .

[0038] like Figure 1As shown, the heat storage tank 22 is used to accommodate the heat exchange medium, and the water supply pipeline 01 is used to replenish the heat exchange medium inside the heat storage tank 22. In actual use, the heat storage cavity is used to accommodate the heat exchange medium, and the heat exchange medium can circulate between the heat exchanger 21 and the heat storage tank 22 through the heat supply pump arranged between the heat exchanger 21 and the heat storage tank 22; the heat storage tank 22 is provided with an electric heating body to heat the heat exchange medium, and the heat exchange medium continuously stores heat under the action of the electric heating body. During the circulation of the heat exchange medium between the heat storage tank 22 and the heat exchanger 21, the heat is continuously transferred to the heat exchanger 21 to heat the sterilizing water or drinking water.

[0039] In some embodiments, Figure 1 As shown, the heat exchanger 21 is provided with a medium channel 211 and a water flow channel 212 which are spaced apart from each other. The medium channel 211 is connected with the heat storage tank 22 to form a heat exchange pipeline 02 for the flow of heat exchange medium. The sterilization water circuit at least includes the heat exchange pipeline 02. The heat exchange medium can be heated to a sterilization temperature inside the heat storage tank 22, which will exceed the sterilization temperature. When the heat exchange medium flows along the heat exchange pipeline 02, the heat exchange pipeline 02 can be sterilized. Since the heat exchange pipeline 02 can be connected with the water pipe 100 through the heat storage tank 22 and the water replenishment tank, if the heat exchange pipeline 02 is bred by bacteria, it may also migrate to the water pipe 100 and have an adverse effect on the water pipe 100. Therefore, sterilizing the heat exchange pipeline 02 is conducive to ensuring the cleanliness of the water pipe 100.

[0040] The water flow channel 212 is connected to the water pipe 100. When drinking water flows through the water flow channel 212, it can exchange heat with the heat exchange medium in the medium channel 211. The sterilization water channel at least includes the water flow channel 212 and a pipeline flowing from the water flow channel 212 to the water outlet 12. The heat exchange medium can heat the drinking water to the sterilization temperature, and then flow to the water outlet 12, thereby sterilizing the above pipeline.

[0041] During sterilization, the sterilizing water flows into the water flow channel 212 from the water inlet end 11, and the sterilizing water inside the water flow channel 212 exchanges heat with the heat exchange medium flowing inside the medium channel 211 to heat the sterilizing water. The heated sterilizing water flows out from the heating outlet pipe to enter the sterilizing water circuit for sterilization.

[0042] When heating drinking water, the drinking water flows into the water flow channel 212 from the water inlet end 11 , and the drinking water in the water flow channel 212 exchanges heat with the heat exchange medium flowing in the medium channel 211 to heat the drinking water.

[0043] According to the above description, since the heat storage tank 22 can use the heat exchange medium inside it to store heat in advance, when heating the sterilization water body and drinking water, the heat stored in the heat exchange medium can be released through the heat exchanger 21. It can be understood that the above-mentioned method of storing heat in advance does not require a high-power electric heating element, and it is low-power and safer to use; and, since the heat is stored in advance, even in the event of a power outage, the heat exchanger 21 can still heat the sterilization water body and drinking water by heat exchange.

[0044] In some embodiments, Figure 1 As shown, the water supply device provided by the present application also includes a refrigeration component 400, which is connected between the water inlet end 11 and the water outlet end 12, and the refrigeration component 400 forms a refrigeration pipeline 03. Drinking water flowing through the refrigeration pipeline 03 can be refrigerated into cold water by the refrigeration component 400, and the sterilization water circuit at least includes the refrigeration pipeline 03 and the pipeline from the refrigeration pipeline 03 to the water outlet end 12. In actual use, the refrigeration pipeline 03 cannot kill bacteria due to the low internal temperature, and can only inhibit the growth of bacteria. Through the above design, the sterilization water flows into the refrigeration pipeline 03 when flowing along the sterilization water circuit, and then kills the bacteria inside the refrigeration pipeline 03, thereby ensuring the health and hygiene of drinking water.

[0045] In some embodiments, the water supply device provided by the present application further includes a water outlet faucet 500, the water outlet faucet 500 is connected to the water outlet end 12, and the sterilization water path at least includes a pipeline from the water outlet end 12 to the water outlet faucet 500 and a pipeline inside the water outlet faucet 500. Based on the above structure, the sterilization water can be discharged through the faucet. Since drinking water is discharged through the water outlet faucet 500 for drinking by users, sterilizing the water outlet faucet 500 can improve the cleanliness and health of drinking water.

[0046] In some embodiments, the water supply device provided by the present application further includes a back-sucking assembly 600 for back-sucking wastewater or sterilizing water, the back-sucking assembly 600 is connected to the waterway pipe 100, and the sterilizing waterway at least includes a pipeline flowing from the waterway pipe 100 to the back-sucking assembly 600 and a pipeline inside the back-sucking assembly 600. In actual use, after the water supply device is discharged, residual water will be retained in the internal pipeline, and this part of the residual water will be discharged first when the water supply device is discharged next time, thereby causing adverse effects on the quality of drinking water discharged by the water supply device next time; the back-sucking assembly 600 can suck out the residual water in the internal pipeline of the water supply device through the back-sucking pipe, thereby ensuring the water quality of the water supply device.

[0047] Since the back-suction component 600 is connected to the water pipe 100, when the sterilization is completed, the sterilization water can be discharged from the water supply device through the back-suction component 600. In the process of the sterilization water flowing from the water pipe 100 to the back-suction component 600 and being discharged through the back-suction component 600, since the sterilization water has a sterilization temperature, it can sterilize the pipeline from the water pipe 100 to the back-suction component 600 and the pipeline inside the back-suction component 600.

[0048] In some embodiments, a drainage pipeline 04 is connected between the above-mentioned back-absorption component 600 and the heat storage tank 22, and the drainage pipeline 04 is used to discharge the heat exchange medium in the heat storage tank 22. The sterilization water circuit at least includes the drainage pipeline 04. The quality of the heat exchange medium in the heat storage tank 22 will be reduced after long-term use, so it is necessary to regularly replace the heat exchange medium inside the heat storage tank 22. When the heat exchange medium inside the heat storage tank 22 is replaced, it can be discharged through the drainage pipeline 04 and the back-absorption component 600, and then replenished through the water replenishment pipeline 01. The heat exchange medium in the heat storage tank 22 is in a high-temperature state and can form a sterilization water body. In the process of discharging the heat exchange medium through the drainage pipeline 04, the heat exchange medium in a high-temperature state can sterilize the waste discharge pipeline and the pipeline inside the back-absorption component 600.

[0049] In some embodiments, the water supply device provided by the present application further includes a control component, which is connected to the heating component and is used to control the heating component to heat the sterilization water to a set range or to heat the drinking water to a set temperature. The control component is provided with a temperature sensor, which is arranged along the sterilization water path. The control component senses the temperature of the sterilization water in the sterilization water path through the temperature sensor. When the temperature of the sterilization water is lower than the sterilization temperature (a pre-set temperature range or temperature value that can kill bacteria), the control component controls the heating component to heat the sterilization water, thereby making the temperature of the sterilization water in the sterilization water path very effective for high-temperature sterilization of the pipes inside the water supply device along the sterilization water path, thereby ensuring the sterilization effect of the water supply device.

[0050] Furthermore, the above-mentioned control component also includes a timing module, which is connected to the control component. When the temperature sensor senses that the temperature of the sterilization water body has reached the sterilization temperature, the timing module is set with a predetermined time so that the control module controls the heating component to maintain the sterilization temperature of the sterilization water body within the predetermined time, ensuring that the pipeline along the sterilization water circuit can be maintained at the sterilization temperature for a sufficiently long time, thereby making the sterilization process more complete.

[0051] It can be understood that in order to ensure that the temperature of the sterilization water always has a sterilization effect when it flows inside the sterilization water channel, multiple temperature sensors are arranged at intervals along the sterilization water channel, and multiple temperature sensors are connected to the control component. In this way, the control component can detect the temperature of the sterilization water in various parts of the entire sterilization water channel, and then the control component can control the heating component to heat the sterilization water to ensure that the sterilization water always has an effective sterilization temperature when it flows, thereby ensuring the stability of the sterilization effect on the pipeline.

[0052] In some embodiments, the water supply device provided by the present application further includes an ion sterilization device, which is arranged along the sterilization waterway and can release sterilization ions. Preferably, the ion sterilization device can release silver ions, which can kill bacteria, and the ion release device is arranged at the water inlet end 11. When the sterilization water enters the sterilization waterway from the water inlet end 11, the ion release device can release silver ions into the sterilization water, so that the sterilization water can carry silver ions to sterilize the pipelines along the sterilization waterway, further improving the sterilization effect of the internal pipelines of the water supply device.

[0053] In other embodiments, the ion release device may be disposed in a heated water outlet pipe. After the sterilizing water enters the heated water outlet pipe, it may be heated to a sterilizing temperature. High temperature is conducive to the release of sterilizing ions by the ion release device.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
