[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] like Figure 1 The water supply device shown includes a water pipe 100, an instant heater 300, and a control component. The water pipe 100 has an inlet 11 for drinking water to flow into it and an outlet 12 for drinking water to flow out. The instant heater 300 is connected between the inlet 11 and outlet 12 of the water pipe 100 to heat the drinking water. The water pipe 100 forms a sterilization water path for supplying sterilization water. The control component is connected to the instant heater 300 to control the instant heater 300 to heat the sterilization water flowing through it to a set range or to heat the drinking water to a set temperature. When the temperature of the sterilization water or drinking water reaches the set range or temperature and flows in the sterilization water path, high-temperature sterilization of the water pipe 100 can be achieved along the sterilization water path, thereby ensuring the health and hygiene of the drinking water.

[0032] The technical details of each component will be introduced below.

[0033] In some implementations, such as Figure 1As shown, the outlet 12 of the instantaneous heater 300 is connected to the water pipe 100 via an instantaneous water outlet pipe 32. The sterilization water path includes at least the instantaneous water outlet pipe 32 and a water path flowing from the instantaneous water outlet pipe 32 to the outlet 12. When the sterilization water heated by the instantaneous heater 300 flows along the sterilization water path, it can perform high-temperature sterilization on the instantaneous water outlet pipe 32 and the water path flowing from the instantaneous water outlet pipe 32 to the outlet 12.

[0034] In some implementations, such as Figure 1 As shown, the water supply device provided in this application has a container for storing hot water. A water replenishment pipe is provided between the water inlet 11 and the container for replenishing the water volume of the container. The instant hot water outlet pipe 32 is also connected to the water replenishment pipe, and the sterilization water path also includes at least the water replenishment pipe. When the sterilization water heated by the instant heater 300 flows along the sterilization water path, it can perform high-temperature sterilization on the instant hot water outlet pipe 32 and the water replenishment pipe.

[0035] In some implementations, such as Figure 1 As shown, the inlet 11 of the instant heater 300 is connected to the water pipe 100 through the instant water inlet pipe 31. The sterilizing water flows through the water pipe 100 at least sequentially through the instant water inlet pipe 31, the instant heater 300, and the instant water outlet pipe 32, and then flows back into the water pipe 100 and can flow back into the instant water inlet pipe 31 through the water pipe 100 to form a circulation pipeline. The sterilizing water path also includes at least a circulation pipeline. A circulation pump 600 is provided along the circulation pipeline to drive the sterilizing water to flow along the circulation pipeline. The circulation pump 600 is provided at the instant water outlet pipe 32 or the instant water inlet pipe 31. Through the above design, the sterilized water or drinking water will flow through the instant heater 300 multiple times during the circulation process in the circulation pipeline to be heated, so that the temperature of the sterilized water or drinking water in the sterilization water circuit will continue to rise until it reaches the set range or set value. At the set range or set value temperature, the sterilized water or drinking water can perform high-temperature sterilization on the pipeline along the sterilization water circuit, thereby ensuring the health and hygiene of drinking water.

[0036] In some implementations, such as Figure 1 As shown, the water supply device provided in this application also includes a back suction component 400 and a faucet 700, both of which are selectively connected to the water pipe 100. The sterilizing water can selectively flow from the water pipe 100 into the back suction component 400 or the faucet 700 and then discharge to form a waste discharge pipe. In practical applications, after the sterilizing water has sterilized the water pipe 100 along the sterilizing water path, it needs to be discharged from the water supply device. Preferably, the sterilizing water is discharged through the faucet 700. In this way, because the sterilizing water is at a high temperature, the pipes inside the faucet 700 can also be sterilized during the discharge process, resulting in more comprehensive sterilization of the water supply device's pipes.

[0037] In some implementations, such as Figure 1 As shown, the hot water outlet pipe 32 is connected to a diversion valve 500, which is divided into a first state and a second state.

[0038] When the diversion valve 500 is in the first state, the instant hot water outlet pipe 32 is connected to the instant hot water inlet pipe 31 through the water pipe 100, the sterilization water is disconnected from the back suction component 400, the sterilization water can circulate along the circulation pipeline, and reach the sterilization temperature (within a predetermined range or predetermined value) under the circulating heating of the instant heater 300 to sterilize the water pipe 100.

[0039] When the diversion valve 500 is in the second state, the instantaneous hot water outlet pipe 32 is connected to the back suction component 400 through the water pipe 100. The sterilizing water can then be discharged from the water pipe 100 through the back suction component 400, preventing the sterilizing water from affecting the water quality of the water supply device. The instantaneous hot water outlet pipe 32 can also be connected to the faucet 700 through the water pipe 100. The sterilizing water can then be discharged from the water pipe 100 through the faucet 700, and during the discharge process, the internal pipes of the faucet 700 can also be sterilized.

[0040] Specifically, such as Figure 1 As shown, the water pipe 100 is provided with a circulation port 13 and a back suction port 14. The circulation port 13 is connected to the water inlet 11, and the back suction port 14 is connected to the back suction assembly 400. The diversion valve 500 includes a water inlet port 51, a first water outlet port 52 and a second water outlet port 53. The water inlet port 51 can be selectively connected to the first water outlet port 52 and the second water outlet port 53. The water inlet port 51 is connected to the instant hot water outlet pipe 32. The first water outlet port 52 and the second water outlet port 53 are respectively connected to the circulation port 13 and the back suction port 14.

[0041] When the inlet port 51 is connected to the first outlet port 52, the diversion valve 500 is in its first state. At this time, the sterilizing water circulates along the sterilizing water path in the water pipe 100 under the action of the circulation pump 600 and is heated by the instantaneous heater 300 to reach the sterilization temperature (within a predetermined range or value). When the inlet port 51 is connected to the second outlet port 53, the diversion valve 500 is in its second state. The sterilizing water can then be discharged from the water pipe 100 through the back suction assembly 400 and also through the faucet 700. Using the diversion valve 500, the connection status of the pipeline can be switched very quickly, making the circulation and discharge process of the sterilizing water easy to control.

[0042] In some implementations, such as Figure 1As shown, the water supply device also includes a heat exchange component 200, which is connected in series with an instant heater 300 to assist the instant heater 300 in heating the sterilizing water, thereby enabling the drinking water to reach the sterilization temperature (within a predetermined range or predetermined value) more quickly.

[0043] The heat exchange component 200 can also be connected in parallel with the instantaneous heater 300, and the heat exchange component 200 can selectively replace the instantaneous heater 300 to heat the sterilized water. In practical applications, in the event of a power outage, the water supply device can also use the heat stored in the heat exchange component 200 to heat the sterilized water to sterilize the sterilized water circuit, thus ensuring drinking water health.

[0044] Specifically, as shown in Figure 1, the heat exchange assembly 200 includes a heat exchanger 21, a heat storage tank 22, and a pump body 23. The heat exchanger 21 and the heat storage tank 22 are connected by a pipe, and the pump body 23 is installed in the pipe. The heat storage tank 22 contains a heat exchange medium for storing heat. The heat exchanger 21 is provided with a drinking water channel 211 and a medium channel 212 that are spaced apart from each other. The heat storage tank 22 is connected to the medium channel 212 of the heat exchanger 21 by a pipe. Driven by the pump body 23, the heat exchange medium circulates between the heat exchanger 21 and the heat storage tank 22 to provide heat to the heat exchanger 21. Inside the heat exchanger 21, the heat of the heat exchange medium flowing inside the medium channel 212 can be transferred to the sterilized water or drinking water flowing in the water channel, thereby heating the sterilized water or drinking water through heat exchange.

[0045] In some implementations, such as Figure 1 As shown, the control components include a temperature sensor, a timing module, and a control module. The control module is connected to the temperature sensor, the timing module, the instant heater 300, and the circulation pump 600, respectively. The temperature sensor is set along the water pipe 100 to detect whether the temperature of the sterilizing water flowing in the water pipe 100 has reached the sterilization temperature.

[0046] In practical use, when the temperature sensor detects that the temperature of the sterilizing water in the water pipe 100 has not reached the sterilization temperature, the control module will control the instant heater 300 to circulate and heat the sterilizing water until the temperature of the sterilizing water reaches the aforementioned sterilization temperature. The timing module can preset the sterilization time, which allows the sterilizing water to continue circulating for the preset time after reaching the sterilization temperature, thereby ensuring the sterilization effect by guaranteeing the temperature and duration of sterilization.

[0047] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
