Description

Technical Field

[0001] This utility model relates to the field of water supply device technology, and in particular to a water supply device. Background Technology

[0002] After a water dispenser has not been used for a long time, bacteria may grow inside the pipes. It is necessary to disinfect the pipes inside the water dispenser regularly. Usually, the drinking water is heated and the pipes inside the water dispenser are disinfected with high temperature. After disinfection, the water needs to be discharged from the water dispenser. Usually, a wastewater drain valve is installed. When draining wastewater, the wastewater drain valve is opened to discharge the disinfected hot water. However, the wastewater drain valve also needs to be connected to a control mechanism or opened manually, which causes inconvenience in terms of structure and operation. Utility Model Content

[0003] To address the structural or operational inconveniences of discharging sterilized hot water in existing technologies, this invention provides a water supply device.

[0004] This application provides a water supply device, including a water pipe, a faucet, and a one-way valve. The water pipe includes an inlet end and an outlet end. The faucet is connected to the outlet end and has an outlet. The one-way valve is connected to the faucet and located near the outlet. The one-way valve has a limiting structure to restrict water flow. When the water pressure in the water pipe reaches a predetermined value, the limiting structure can move from a closed state to an open state to allow water flow.

[0005] In some embodiments, the water supply device includes at least two of the one-way valves, each of the one-way valves being connected in series along the water outlet direction of the faucet.

[0006] In some embodiments, the water pipe is formed into a sterilization water passage for supplying sterilization water.

[0007] The water supply device also includes a circulation pump, which is installed in the sterilization water path to drive the sterilization water to circulate along the sterilization water path.

[0008] In some embodiments, the circulation pump includes a circulation state and a discharge state. When the circulation pump is in the circulation state, the circulation pump drives the sterilizing water to flow, and the water pressure of the sterilizing water during circulation is less than the predetermined value. When the circulation pump is in the discharge state, the circulation pump can increase the water pressure of the sterilizing water to a value greater than the predetermined value.

[0009] In some embodiments, the water supply device further includes a heat exchange component and / or an instantaneous heater, the heat exchange component and the instantaneous heater being arranged along the sterilization water path to heat the sterilization water.

[0010] In some embodiments, the heat exchange component and / or the instantaneous heater form a heating device, the heating device being provided with an inlet pipe and an outlet pipe, both of which are connected to the water pipe.

[0011] The circulating pump is installed in the inlet pipe or the outlet pipe;

[0012] The sterilizing water flows through the inlet pipe, the heating device, the outlet pipe, and the water pipe in sequence, and then flows back into the inlet pipe through the water pipe to form a circulation.

[0013] In some embodiments, the water outlet pipe is optionally connected to the faucet via the water pipe, and the sterilizing water flows out of the water outlet pipe, enters the water pipe, and then flows to the faucet for discharge.

[0014] In some embodiments, the water supply device further includes a waste discharge component, which is connected to the water pipe. The outlet pipe is selectively connected to the waste discharge component through the water pipe. The sterilizing water flows out of the outlet pipe, into the water pipe, and then into the waste discharge component for discharge.

[0015] In some embodiments, the waste discharge assembly includes a back suction pipe, a waste discharge pump, and a waste discharge pipe. The back suction pipe and the waste discharge pipe are respectively connected to the suction inlet and discharge outlet of the waste discharge pump. The water outlet pipe can be selectively connected to the back suction pipe through the water pipe.

[0016] In some embodiments, the heat exchange assembly includes a heat exchanger and a heat storage tank. The heat exchanger is provided with water flow channels and medium channels that are spaced apart from each other. The heat storage tank is provided with a water inlet and a water outlet. The heat storage tank is provided with a heat storage cavity inside, and the heat storage cavity contains a heat exchange medium. The water inlet and the water outlet are both connected to the heat storage cavity.

[0017] Compared with existing technologies, the water supply device provided by this utility model has the following advantages: When sterilizing the water pipes, because the one-way valve has a predetermined outlet resistance, the sterilizing water will not be directly discharged from the faucet after flowing into the faucet. Therefore, the sterilizing water can remain in the water pipes to fully kill bacteria. After sterilization, the sterilizing water in the water pipes is pressurized to exceed a predetermined pressure, allowing it to be discharged from the faucet through the one-way valve. This process requires no additional valve structure and eliminates the need for manual valve opening by the user, ensuring thorough sterilization while conveniently discharging the sterilized water.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] like Figure 1 The water supply device shown includes a water pipe 100, a faucet 200, and a one-way valve 300. The water pipe 100 includes an inlet end 11 and an outlet end 12. Drinking water flows in through the inlet end 11 and then flows out through the outlet end 12. The faucet 200 is connected to the outlet end 12 and is provided with an outlet 21 for discharging water. The one-way valve 300 is connected to the faucet 200 and is located near the outlet 21. The one-way valve 300 is provided with a limiting structure 32 to restrict the flow of water. When the water pressure in the water pipe 100 reaches a predetermined value, the limiting structure 32 can move from a closed state to an open state to allow water to flow through. With the above design, when sterilizing the water pipe 100, because the one-way valve 300 has a predetermined outlet resistance, the sterilizing water will not be directly discharged from the faucet 200 after flowing through the one-way valve 300. Therefore, the sterilizing water can remain in the water pipe 100 to effectively kill bacteria. After sterilization, the sterilizing water in the water pipe 100 is pressurized to exceed a predetermined pressure, allowing the sterilizing water to be discharged from the faucet 200 through the one-way valve 300. This process requires no additional valve structure and eliminates the need for manual valve opening by the user, ensuring thorough sterilization while conveniently discharging the sterilized water.

[0027] The technical details of each component will be introduced below.

[0028] In some implementations, such as Figure 1 As shown, the water supply device provided in this application includes at least two one-way valves 300, each one-way valve 300 being connected in series along the water outlet direction of the faucet 200. In actual use, the one-way valves 300 may leak. By connecting the two one-way valves 300 in series, even if one one-way valve 300 leaks, the other one-way valve 300 can still prevent the sterilizing water from flowing directly out of the faucet 200 during the sterilization process, greatly reducing the possibility of the sterilizing water leaking out of the faucet 200 during the sterilization process.

[0029] Furthermore, the water supply device of this application also includes a detection mechanism connected to each one-way valve 300. The detection mechanism is used to detect whether each one-way valve 300 leaks. If leakage is found, the detection mechanism can display the leakage status of the one-way valve 300 through sound, light, and other information, making it convenient for the user to know and replace the one-way valve 300. In actual use, the probability of multiple one-way valves 300 failing simultaneously is very low. Therefore, by combining the above-mentioned scheme of connecting at least two one-way valves 300 in series with the detection mechanism, leakage of the water supply device during the sterilization process can be effectively prevented.

[0030] In some implementations, such as Figure 1 As shown, the one-way valve 300 includes a housing 31 and a limiting structure 32. The housing 31 has an inlet chamber 311 and an outlet chamber 312, with a connecting port 01 between them. The limiting structure 32 is connected to the housing 31 and can selectively close the connecting port 01. When the limiting structure 32 is in a closed state, it closes the connecting port 01; when it is in an open state, the inlet chamber 311 and the outlet chamber 312 are connected through the connecting port 01. In actual use, drinking water first enters the inlet chamber 311. When the water pressure inside the inlet chamber 311 exceeds a predetermined value, the limiting structure changes from a closed state to an open state. At this time, the connecting port 01 opens, allowing drinking water to enter the outlet chamber 312 from the inlet chamber 311 and then flow through the one-way valve 300 before being discharged. The limiting structure 32 abuts against the connecting port 01 and can control the connection state between the inlet chamber 311 and the outlet chamber 312 according to the water pressure of the inlet chamber 311. During sterilization, the water pressure of the sterilizing water is lower than a predetermined value, and the sterilizing water can continue to exist in the water pipe 100 to fully sterilize the water pipe 100. After sterilization, the water pressure of the sterilizing water is increased by the water pump installed inside the water supply device, so that the water pressure of the sterilizing water in the inlet chamber 311 exceeds the predetermined value, causing the limiting structure 32 to open. The sterilizing water can then enter the outlet chamber 312 from the inlet chamber 311 through the connecting port 01 and finally be discharged from the faucet 200. The discharge process is convenient and does not require manually opening the valve.

[0031] In some implementations, such as Figure 1 As shown, the aforementioned limiting structure 32 is provided with an elastic element 33, which abuts against the limiting structure 32 so that the limiting structure 32 abuts against the edge of the connecting port 01. The elastic element 33 allows the limiting structure 32 to elastically abut against the connecting port 01. When the water pressure on the abutting structure exceeds the elastic force of the elastic element 33, the abutting element will disengage from the connecting port 01, and the water flow can enter the outlet chamber 312 through the inlet chamber 311. Therefore, the elastic element 33 enables the one-way valve 300 to have a predetermined outlet resistance, thereby preventing the sterilizing water from being directly discharged through the faucet 200 during the sterilization process.

[0032] In some implementations, such as Figure 1As shown, the one-way valve 300 also includes an adjusting member 34, which is disposed between the elastic member 33 and the housing 31 to adjust the elastic force of the elastic member 33 relative to the limiting structure 32; one end of the adjusting member 34 passes through the housing 31 and is threadedly connected to the housing 31, and the other end abuts against the end of the elastic member 33 away from the limiting structure 32; wherein, when the adjusting member 34 rotates relative to the housing 31, the adjusting member 34 can press or release the elastic member 33. The aforementioned adjusting member 34 can be a screw, and the aforementioned elastic member 33 can be a spring. Since the adjusting member 34 is threadedly connected to the housing 31, it will move relative to the housing 31 when rotating. During the movement, one end of the adjusting member 34 will press against or move away from the elastic member 33, thereby changing the elastic force of the elastic member 33. When the adjusting member 34 presses against the elastic member 33, the elastic force of the elastic member 33 increases, thereby increasing the effect of the limiting structure 32 against the edge of the connecting port 01. Consequently, a greater water pressure needs to be generated inside the water inlet cavity 311 to push the limiting structure 32 away from the connecting port 01. 1. This means that the water outlet resistance of the one-way valve 300 increases. When the adjusting member 34 moves away from the elastic member 33, the elastic force of the elastic member 33 decreases, which in turn reduces the effect of the limiting structure 32 against the edge of the connecting port 01. Consequently, the predetermined value of the water pressure that can push the limiting structure 32 away from the connecting port 01 inside the water inlet chamber 311 decreases, which means that the water outlet resistance of the one-way valve 300 decreases. In summary, by rotating the adjusting member 34, the water outlet resistance of the one-way valve 300 can be adjusted, so that the water outlet resistance of the one-way valve 300 can be changed according to the actual situation in production and daily use. Specifically, after prolonged use, the elasticity of the elastic element 33 will decrease, resulting in a smaller water outlet resistance of the one-way valve 300. At this time, the adjusting element 34 can be rotated to press the elastic element 33 tightly. In this way, the elasticity of the elastic element 33 against the limiting structure 32 can be restored, thereby restoring the water outlet resistance of the one-way valve 300 and extending the service life and stability of the one-way valve 300.

[0033] In other embodiments, the one-way valve 300 may be a duckbill valve, which has a certain water outlet resistance and can also prevent water from flowing in the opposite direction.

[0034] In some implementations, such as Figure 1As shown, the water pipe 100 forms a sterilization water path for supplying sterilization water. The water supply device also includes a circulation pump, which is installed in the sterilization water path to drive the sterilization water to circulate along the path. The water supply device also includes a heating component connected to the water pipe 100. The heating component heats the sterilization water, and the circulation pump allows the sterilization water to circulate along the water pipe 100. During the circulation of the sterilization water, the heating component continuously heats the water, maintaining a high temperature to ensure sufficient sterilization effect. It is understood that during circulation, the sterilization water will not pass through the one-way valve 300 due to its predetermined outlet resistance, thus remaining continuously in the water pipe 100 for circulation.

[0035] In some embodiments, the aforementioned circulating pump includes a circulating state and a discharging state. When the circulating pump is in the circulating state, it drives the sterilizing water to flow, and the water pressure during the circulating flow of the sterilizing water is less than a predetermined value. When the circulating pump is in the discharging state, it can increase the water pressure of the sterilizing water to a value greater than the predetermined value. The circulating pump allows for very convenient control of the water pressure of the sterilizing water, facilitating the circulation and discharge of the sterilizing water.

[0036] In some embodiments, the water supply device provided in this application further includes a heat exchange component 400 and / or an instantaneous heater 500, wherein the heat exchange component 400 and the instantaneous heater 500 are arranged along the sterilization water path to heat the sterilization water.

[0037] like Figure 1 As shown, the water supply device also includes a heat exchange component 400 and an instant heater 500. The heat exchange component 400 heats the sterilization water through heat exchange, while the instant heater 500 heats the sterilization water directly through electric heating. When the heat of the heat exchange component 400 is insufficient, the instant heater 500 can be used to heat the sterilization water, thus providing an effective guarantee for the heat source of the sterilization water.

[0038] In some implementations, such as Figure 1As shown, a heat exchange component 400 and / or an instantaneous heater 500 form a heating device. The heating device is equipped with an inlet pipe 001 and an outlet pipe 002, both of which are connected to a water pipe 100. A circulation pump is installed in the inlet pipe 001 or the outlet pipe 002 to drive the flow of the sterilizing water. The sterilizing water flows through the inlet pipe 001, the heating device, the outlet pipe 002, and the water pipe 100 at least sequentially, and then flows back into the inlet pipe 001 through the water pipe 100 to form a circulation. Through the above design, the sterilizing water can circulate along the above water path, so that the sterilizing water can be heated multiple times by the heating device under the drive of the circulation pump. It is understandable that during the flow of sterilizing water in the pipeline, the pipeline will absorb heat from the sterilizing water, causing the temperature of the sterilizing water to drop, which in turn affects the sterilization effect of the sterilizing water. Through the above-mentioned circulating heating method, the sterilizing water can be fully heated during the circulation process, thereby ensuring that the sterilizing water has a sufficient temperature to sterilize the pipeline.

[0039] In some implementations, such as Figure 1 As shown, the water outlet pipe 002 is optionally connected to the faucet 200 via the water pipe 100. The sterilizing water flows out of the outlet pipe 002, enters the water pipe 100, and then flows to the faucet 200 for discharge. In actual use, the sterilizing water needs to be discharged from the water dispenser after sterilization. Using the above method, the sterilizing water can be discharged through the faucet 200. Furthermore, during the discharge process, the sterilizing water can also sterilize the internal pipes of the faucet 200.

[0040] In some implementations, such as Figure 1 As shown, the water supply device provided in this application also includes a waste discharge component 600, which is connected to the water pipe 100. The outlet pipe 002 can be selectively connected to the waste discharge component 600 via the water pipe 100. Sterilized water flows out of the outlet pipe 002, into the water pipe 100, and then into the waste discharge component 600 for discharge. 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 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 waste discharge component 600 can promptly remove the residual water from the water pipe 100 via the waste discharge pipe 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. Furthermore, during the process of the sterilizing water being discharged through the waste discharge component 600, the sterilizing water can also sterilize the pipes inside the waste discharge component 600.

[0041] Specifically, such as Figure 1 As shown, the aforementioned waste discharge assembly 600 includes a back suction pipe, a waste discharge pump, and a waste discharge pipe. The back suction pipe and the waste discharge pipe are respectively connected to the suction inlet and discharge outlet of the waste discharge pump. The water outlet pipe 002 can be selectively connected to the back suction pipe via the water pipe 100. Under the action of the back suction pump, residual water and sterilization water in the water pipe 100 can be drawn into the back suction pump through the back suction pipe and then discharged.

[0042] In some implementations, such as Figure 1 As shown, the heat exchange assembly 400 includes a heat exchanger 41 and a heat storage tank 42. The heat exchanger 41 is provided with a water flow channel 411 and a medium channel 412 that are spaced apart from each other. The heat storage tank 42 is provided with a water inlet 421 and a water outlet 422, which are connected to the two ends of the medium pipeline. The heat storage tank 42 is provided with a heat storage cavity inside, which contains the heat exchange medium. Both the water inlet 421 and the water outlet 422 are connected to the heat storage cavity.

[0043] It should be noted that a heat exchange pump is installed between the heat exchanger 41 and the heat storage tube. Under the action of the heat exchange pump, the heat exchange medium inside the heat storage tube flows out of the heat storage tube from the water outlet 422 and enters the medium channel 412 of the heat exchanger 41. After heat exchange, the heat exchange medium flows out from the medium channel 412 and then flows back into the heat storage tube through the water inlet 421, and the cycle repeats as described above. A heater is installed inside the heat storage tank 42 to heat the heat exchange medium. When the heat exchange assembly 400 is working, the high-temperature heat exchange medium flows from the heat storage tank 42 into the heat exchange channel of the heat exchanger 41. The heat of the heat exchange medium inside the heat exchange channel is transferred to the drinking water inside the water flow channel 411 to heat the drinking water. The heat exchange medium can store heat in advance. The heat exchanger 41 can continuously transfer the heat in the heat storage tank 42 to the sterilization water, so that the sterilization water reaches the predetermined sterilization temperature. The instantaneous heater 500 is connected to the heat exchanger 41 through the water flow channel 411; the instantaneous heater 500 can heat the sterilization water when the heat inside the heat storage tank 42 is insufficient.

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.

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used merely 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.
