[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] See also Figure 1 As shown, Figure 1 A schematic diagram of the structure of a water supply device 1 provided in an embodiment of the present invention, the water supply device 1 comprises: a water inlet module 10, a water outlet module 30, a drainage module 50 and a control module 60, the water supply device further comprises a heating module 20 and / or a cooling module 40;

[0047] The water inlet module 10 is connected to the heating module 20 and / or the refrigeration module 40, and the water inlet module 10 is also connected to the water outlet module 30, for controlling the amount of water entering the water supply device;

[0048] The heating module 20 is connected to the water inlet module 10 and the water outlet module 30, and is used to heat the water entering the heating module 20 through a heat exchange unit, and store a heat exchange medium for heating;

[0049] The water outlet module 30 is connected to the heating module 20 and / or the refrigeration module 40, and the water outlet module 30 is also connected to the water inlet module 10 and the drainage module 50, and is used to output water that meets the preset temperature. The water inlet module 10 and the heating module 20 and / or the refrigeration module 40 share the water outlet waterway in the water outlet module;

[0050] The drainage module 50 is connected to the water outlet module 30, and is also connected to the refrigeration module 40 and / or the heating module 20, and is used to assist the water path reflux of the heating module 20 and / or the refrigeration module 40, and to discharge the waste water of the water outlet module 30, and to discharge the waste water of the heating module 20 and the refrigeration module 40;

[0051] The control module 60 is connected to the water inlet module 10, the water outlet module 30, and the drainage module 50. The control module 60 is also connected to the heating module 20 and / or the refrigeration module 40, and is used to control the water inlet module 10, the drainage module 50, and the water outlet module 30 to work, and is also used to control the refrigeration module 40 and / or the heating module 20 to work.

[0052] Since the hot water and the flow-increasing water circuits have relatively low requirements for flow, in order to save space and material costs while meeting the functions, the hot water and the flow-increasing water circuits can use relatively small diameter pipes, such as 2-branch pipes. The usage of the normal temperature and cold water circuits may be relatively large, and the normal temperature and cold water can use relatively large diameter pipes, such as 3-branch pipes, which are not limited in this application. Among them, the heat exchange medium may include water, oil, etc., which are not limited in this application.

[0053] It should be noted that the heating module, the cooling module, and the water inlet module can share the water outlet waterway in the water outlet module, that is, the water outlet waterways of normal temperature water, hot water, and cold water can be shared, which can not only reduce consumables and avoid excessive space occupancy in the water supply device, but also improve the diversity and practicality of the waterway functions. Furthermore, a reflux and re-absorption waterway can be combined to avoid residual water affecting the next water use.

[0054] In this embodiment, the water inlet module 10 is first used to control the amount of water entering the water supply device 1, and the water entering the heating module is heated and stored through the heating module 20, and then the water outlet module 30 outputs water that meets the preset temperature, and the drainage module 50 can assist the water path reflux of the heating module 20 and the refrigeration module 40, and discharge the waste water of the heating module 20, the water outlet module 30, and the refrigeration module 40, and further control the water inlet module 10, the heating module 20, the water outlet module 30, the refrigeration module 40 and the drainage module 50 to work through the control module 60, so as to achieve stable heating of the water entering the water supply device 1, and effectively perform temperature feedback and real-time adjustment mechanism, so as to achieve the purpose of more stably supplying water that meets the preset temperature.

[0055] See also Figure 2 As shown, Figure 2 A schematic diagram of a water path structure of a water outlet module 30 provided in an embodiment of the present invention. The water outlet module comprises a first control valve 31, a water temperature detector 32 and a water outlet valve 33, wherein a first end of the first control valve 31 is connected to the water outlet path of the heating module 20 and the water inlet module 10, a second end of the first control valve 31 is connected to the water outlet path of the refrigeration module 40 and the water inlet end of the water outlet valve 33, and the water temperature detector 32 is disposed adjacent to the water inlet end of the water outlet valve 33;

[0056] The water temperature detector 32 is used to detect the temperature of water entering the water inlet end of the water outlet valve;

[0057] The first control valve 31 is used to control the water from the water inlet module 10 to enter the water outlet waterway in the water outlet module 30, and to control the water from the heating module 20 to enter the water outlet waterway in the water outlet module 30;

[0058] The water outlet valve 33 is used to control the water outlet of the water outlet module 30 .

[0059] In one possible implementation, see Figure 3 As shown, Figure 3 A schematic diagram of the water path structure of another water outlet module 30 provided in an embodiment of the present invention. The water outlet module 30 includes a first control valve 31, a water temperature detector 32 and a water outlet valve 33, wherein a first end of the first control valve 31 is connected to the water inlet module 10, a second end of the first control valve 31 is connected to the water outlet water path of the refrigeration module 40 and / or the water outlet water path of the heating module 20, and is also connected to the water inlet end of the water outlet valve 33, and the water temperature detector 32 is disposed adjacent to the water inlet end of the water outlet valve 33.

[0060] In one possible implementation, see Figure 4 As shown, Figure 4 A schematic diagram of a water path structure of another water outlet module 30 provided in an embodiment of the present invention. The water outlet module 30 includes a first control valve 31, a water temperature detector 32 and a water outlet valve 33, wherein a first end of the first control valve 31 is connected to the water outlet water path of the heating module 20 and / or the water outlet water path of the refrigeration module 40, and is also connected to the water inlet module 10; a second end of the first control valve 31 is connected to the water inlet end of the water outlet valve 33, and the water temperature detector 32 is disposed adjacent to the water inlet end of the water outlet valve 33.

[0061] Among them, the first control valve 31 can be a two-way valve (such as called the first two-way valve 31), and the two-way valve is used as an example in the figure for illustration, which does not constitute a limitation on the present application. The water temperature detector 32 can be a negative temperature coefficient (Negative Temperature Coefficient, NTC) thermistor 32, and the NTC thermistor is used as an example in the figure for illustration, which does not constitute a limitation on the present application. The water outlet valve 33 can be a one-way valve 33 (such as called the first one-way valve 33), and the one-way valve is used as an example in the figure for illustration, which does not constitute a limitation on the present application.

[0062] It should be noted that the water outlet module 30 can perform accurate water temperature detection to further perform water temperature screening and waterway diversion. Through the above strict temperature screening mechanism, the entire water supply device system can always provide users with stable water that meets temperature requirements, which can not only improve user satisfaction, but also improve the practicality of the entire system.

[0063] Optionally, the diversion function of the water outlet module 30 also contributes to the stable operation of the system. After the water with unqualified water temperature is discharged to the drainage module 50, the system can take corresponding measures according to the specific situation, such as reheating the water with unqualified water temperature, or checking whether the instant heating unit 23, the heat exchange unit 21 and the heating energy storage unit 22 are faulty, etc., so as to ensure the continuous and stable operation of the entire system.

[0064] In one possible implementation, Figure 2 As shown, the water outlet module 30 also includes a water outlet 34. Optionally, the exhaust unit on other modules (such as the exhaust unit 24 on the heating module to be mentioned below) can be connected to the water outlet 34 to discharge the gas generated during the operation of the water system through the water outlet 34, thereby avoiding the adverse effects of gas accumulation on the system.

[0065] It is understandable that the first two-way valve 31 can be used to deliver water from the instant heating unit 23 to the NTC thermistor 32; optionally, the first two-way valve 31 can also be used to deliver water from the water inlet module 10 to the drainage module 50. Optionally, the NTC thermistor 32 can be used to detect the water temperature and deliver water that meets the preset water temperature to the water outlet, and deliver water that does not meet the preset water temperature to the drainage module 50 through the first two-way valve 31.

[0066] In a possible implementation, the first one-way valve 33 is used to control the discharge of the first type of liquid from the water outlet module and prevent the second type of liquid from entering from the outside.

[0067] The first type of liquid may be a liquid required in the water system of the water supply device, such as sterilizing water when sterilization is required, or high temperature water when high temperature flushing is required. The second type of liquid may be a liquid not required by the external water supply device, such as coffee, milk, etc., which is not limited in this application.

[0068] The first one-way valve 33 can be used to control the direction of water flow to ensure that water can only flow in a specific direction. Its pressure can be evaluated to determine whether it can work normally under different pressure conditions, thereby preventing problems such as backflow and ensuring the normal operation of the water system. The first one-way valve 33 in the embodiment of the present application can prevent sterilizing water from being discharged from the faucet and prevent external liquids (such as coffee, etc.) from being sucked back into the water channel, thereby keeping the water system clean and preventing pollution, etc., which is not limited by the present application.

[0069] When the heated water flows to the water outlet 34, the NTC thermistor 32 installed in the internal waterway will monitor the water temperature in real time. The resistance value of the NTC thermistor 32 is negatively correlated with the temperature, that is, the resistance value decreases when the temperature increases, and the resistance value increases when the temperature decreases. When the water temperature reaches the set qualified temperature, the resistance value of the NTC thermistor 32 is in the normal range. At this time, the control module 60 will keep the wastewater waterway of the drainage module 50 closed to provide water with the required temperature for users.

[0070] The precise temperature control mechanism mentioned above can ensure that the output water always meets the temperature requirements, and will not be affected by the water temperature fluctuating, and can avoid the wasteful discharge of water that does not meet the temperature requirements. Recirculating the water that does not meet the temperature requirements for reheating instead of reheating all the water helps save energy and improve the energy efficiency of the water supply device.

[0071] See also Figure 5 As shown, Figure 5 A schematic diagram of a waterway structure of a drainage module 50 provided in an embodiment of the present invention, wherein the drainage module 50 comprises a second control valve, a wastewater pump 52 and a drainage component 53, wherein the drainage component 53 is connected to the wastewater pump 52 and the second control valve;

[0072] The second control valve is used to control the wastewater of the water outlet module 30 transmitted to the drainage component 53 by the wastewater pump 52; the wastewater of the heating module 20 transmitted to the drainage component 53 by the wastewater pump 52; and the wastewater of the refrigeration module 40 transmitted to the drainage component 53 by the wastewater pump 52;

[0073] The wastewater pump 52 is used to transfer the wastewater of the heating module 20 and / or the wastewater of the refrigeration module 40, as well as the wastewater of the water outlet module 30 to the drainage component 53;

[0074] The drainage component 53 is used to discharge waste water from the heating module 20 and / or waste water from the refrigeration module 40 and the water outlet module 30 .

[0075] The drainage component 53 may be a component for discharging water (such as waste water). The drainage component 53 may be a drainage pipe, a drainage valve or a drainage port, or a specific drainage container, which is not limited in the present application. The above components cooperate to ensure the effective treatment of waste water in the water system of the water supply device.

[0076] In one possible implementation, Figure 5As shown, the second control valve can be a three-way valve 51 (such as called the first three-way valve 51), the first water channel interface of the first three-way valve 51 is connected to the water outlet module 30 through the water channel, the second water channel interface of the first three-way valve 51 is connected to the heating module 10 and the refrigeration module 40 through the water channel, and the third water channel interface of the first three-way valve 51 is connected to the wastewater pump 52 through the water channel.

[0077] Among them, the first three-way valve 51 can distribute the water flow to three different directions. The first three-way valve 51 can switch between different waterway branches or mix water flows, etc. The first three-way valve 51 can not only regulate the water flow path, but also work in coordination with other modules. For example, when the water temperature does not meet the preset water temperature, the first three-way valve 51 can change the water flow path to guide the substandard water to one end of the wastewater pump 52 connected to it, so as to prepare for the subsequent reflux and reheating of the water.

[0078] It should be noted that the wastewater pump 52 can be used to provide power for the water circuit to reflux, so as to reflux and reheat the water that does not meet the preset water temperature. When the water temperature does not meet the requirements, the wastewater pump 52 can generate power through its own operation to drive the substandard water to flow in the reverse direction along the predetermined water circuit. For example, the water that was originally to flow out of the water outlet module 30 but was not at a high enough temperature is transferred in the reverse direction to the heating module 20 through the switching of the first three-way valve 51, so that the water can return to the heating module 20 for reheating, so as to ensure that the final output water meets the water temperature standard, thereby ensuring that the user can use water at the appropriate temperature.

[0079] The reflux power provided by the wastewater pump 52 can make the water temperature control of the entire water supply system more accurate and stable, avoiding the water that does not meet the temperature standard from directly flowing out and being used by users; and since only the part of the water that does not meet the temperature standard needs to be reheated instead of reheating all the water, it also helps to improve the energy efficiency of the entire system.

[0080] In one possible implementation, see Figure 6 As shown, Figure 6 A schematic diagram of the water path structure of another drainage module 50 provided in an embodiment of the present invention, the drainage module 50 includes a third control valve, a wastewater pump 52 and a drainage component 53, wherein the third control valve is a one-way valve 54 (such as called a second one-way valve 54), the first water path interface of the second one-way valve 54 is connected to the water outlet module 30 through a water path, the second water path interface of the second one-way valve 54 is connected to the heating module 20, the refrigeration module 40, and the wastewater pump 52 through a water path, and the wastewater pump 52 is connected to the drainage component 53.

[0081] The second one-way valve 54 can be used to control the wastewater flowing from the water outlet module 30 to the drainage component 53. The wastewater may include excess water generated during the reheating process when the temperature does not meet the preset water temperature, as well as some impurity water generated during the operation of the system, water discharged during maintenance, etc. By discharging the wastewater from the system through the wastewater outlet 43, the entire water system can be kept clean, the accumulation of impurities can be prevented from adversely affecting the normal operation of the system and the water quality, and the service life of the system can be extended.

[0082] See also Figure 7 As shown, Figure 7 A schematic diagram of a water path structure of a heating module 20 provided in an embodiment of the present invention, wherein the heating module 20 includes a heat exchange unit 21, a heating energy storage unit 22 and an instant heating unit 23, wherein the heat exchange unit 21 is connected to the water inlet module 10 and the instant heating unit 23, the instant heating module is connected to the water outlet module 30, and the heating energy storage unit 22 is connected to the refrigeration module 40 via a bridging water path;

[0083] The heat exchange unit 21 is used to heat the water entering the heating module 20;

[0084] A heating energy storage unit 22, used to store the heat exchange medium entering the heating energy storage unit 22 and / or heat the heat exchange medium entering the heating energy storage unit 22;

[0085] That is, the heating unit 23 is used to transmit the water output by the heat exchange unit 21 and / or to heat the water output by the heat exchange unit 21;

[0086] The refrigeration module 40 is also used to replenish water to the heating energy storage unit 22 through the bridging water path.

[0087] The heat exchange unit 21 may be a device that transfers heat from one fluid to another fluid by heat conduction, convection, radiation, etc. The larger the heat transfer area of ​​the heat exchange module, the more heat can be transferred under the same conditions, and the higher the heating efficiency. In the solution provided in the present application, the heat transfer area of ​​the heat exchange module can be designed to be large enough to achieve the purpose of more effectively transferring heat to the fluid.

[0088] It can be understood that compared with direct heating methods (such as electric heating, flame heating, etc.), the heat exchange unit 21 has a higher energy utilization rate. For example, the heat exchange unit 21 can use industrial waste heat, residual heat, etc. for heating to greatly improve energy utilization and reduce energy waste; the heat exchange unit 21 has precise temperature control, such as precise temperature control can be achieved by adjusting parameters such as the flow rate and temperature of the fluid; the heat exchange unit 21 has high safety. Compared with flame heating and other methods, the heat exchange unit 21 has no open flame and has greater safety advantages.

[0089] The medium of the heating energy storage unit 22 can be water or oil, and this application does not limit this. The heating energy storage unit 22 can be a hot tank, which is a tank with a heat storage function, and can store heated water to meet the user's demand for hot water within a certain period of time, playing the role of buffering and continuously supplying hot water.

[0090] The instant heating unit 23 can be used to quickly heat water. Combining the instant heating unit 23 with the heat storage function of the heating energy storage unit 22 can provide water at a preset temperature quickly when needed, thereby improving the efficiency of supply.

[0091] In one possible implementation, Figure 7 As shown, the heating module 20 further includes an exhaust unit 24, a first end of the exhaust unit 24 is connected to the heating energy storage unit 22, and a second end of the exhaust unit 24 is connected to the water outlet module 30. Optionally, the exhaust unit 24 is connected to a water outlet 34 to discharge the gas generated during the operation of the water system through the water outlet 34, thereby preventing the gas accumulation from causing adverse effects on the system.

[0092] It should be noted that the exhaust unit 24 may include an exhaust pipe, which may be a pipe with a larger diameter, such as a three-branch pipe. During the operation of the water system, gas may be generated, and the three-branch pipe can better discharge the gas to avoid adverse effects of gas accumulation on the system, such as pressure abnormality.

[0093] In one possible implementation, Figure 7 As shown, the heating module 20 further includes a circulating water pump 25, which is connected to the heating energy storage unit 22 and the heat exchange module 21, wherein:

[0094] The circulating water pump 25 is used to transport the water stored in the heating energy storage unit 22 to the heat exchange unit 21 .

[0095] In one possible implementation, see Figure 8 As shown, Figure 8 A schematic diagram of replenishing air through the water outlet component 301 of the water outlet module 30 provided in an embodiment of the present invention, the heating module 20 also includes an exhaust unit 24, the first end of the exhaust unit 24 is connected to the heating energy storage unit 22, and the second end of the exhaust unit 24 is connected to the water outlet component 301 of the water outlet module 30, the exhaust unit 24 is also used to replenish air to the wastewater pump 52 in the drainage module 50 through the water outlet component 301 when draining wastewater in the water outlet module 30; replenish air to the wastewater pump 52 in the drainage module 50 through the water outlet component 301 when draining wastewater in the refrigeration module 40; replenish air to the wastewater pump 52 in the drainage module 50 through the water outlet component 301 when draining wastewater in the heating energy storage unit 22.

[0096] Among them, the water outlet component 301 can be a component that provides water (to the user). The water outlet component 301 can be a faucet, a shower, a nozzle or a water outlet, etc. Taking the water outlet component 301 as a faucet as an example, the exhaust port of the faucet can be used to replenish air to the drainage power component (i.e., the wastewater pump 52), and this application does not limit this. When the wastewater pump 52 drains the wastewater in the water outlet module 30, when the wastewater in the refrigeration module 40 is drained, and when the wastewater in the heating energy storage unit 22 is drained, the drainage process will cause the pressure in the pipeline to change. Inflation can prevent negative pressure from occurring during the drainage process. By replenishing air, the pressure in the pipeline can be kept relatively stable, ensuring that the wastewater pump 52 can work continuously and stably, and helping to improve the drainage efficiency of the wastewater pump 52.

[0097] In one possible implementation, see Fig. 9 As shown, Fig. 9 A schematic diagram of replenishing air through the air hole 302 of the water outlet module 30 provided in an embodiment of the present invention. The exhaust unit 24 is also used to replenish air to the wastewater pump 52 in the drainage module 50 through the air hole 302 of the water outlet module 30 when draining wastewater in the water outlet module 30; replenish air to the wastewater pump 52 in the drainage module 50 through the air hole 302 when draining wastewater in the refrigeration module 40; replenish air to the wastewater pump 52 in the drainage module 50 through the air hole 302 when draining wastewater in the heating energy storage unit 22.

[0098] The wastewater pump 52 can be supplied with air through the air hole 302 of the water outlet module 30. Specifically, a one-way valve can be installed at the air hole 302 to evacuate the water in the pipeline. Optionally, the air hole 302 and the one-way valve can be realized by a compressible water bag.

[0099] See also Fig.10 As shown, Fig.10 The water path structure diagram of a water inlet module 10 provided in an embodiment of the present invention. The water inlet module 10 includes a water inlet 11, a flow meter unit 12 and a flow control unit 13, wherein the water inlet 11 is connected to the flow meter unit 12 and the flow control unit 13, and the flow control unit 13 is connected to the water outlet module 30 and the refrigeration module 40, wherein:

[0100] The flow meter unit 12 is used to measure the water flow to the heating module 20;

[0101] The flow control unit 13 is used to control the flow of water entering the water outlet module 30 , the heating module 20 , and the refrigeration module 40 .

[0102] It should be noted that the water inlet 11 is the entrance for water to enter the water system of the water supply device and is the starting point of the entire water circulation. External water sources can enter the water system of the water supply device through the water inlet 11. The flow meter unit 12 can be used to measure the water flow input to the heat exchange unit 21. By measuring the water flow entering the heat exchange unit 21, the system can better control the heating process. For example, the heating power is adjusted according to the flow rate to ensure that the water can be fully and efficiently heated; if the flow rate is large, the heating power may need to be increased; if the flow rate is small, the heating power can be appropriately reduced to avoid energy waste.

[0103] The flow control unit 13 can control the flow of water entering the water outlet module 10 and the refrigeration module 40 to better control the water flow according to the requirements (such as the user's requirements for the output of hot water, the safety restrictions of the system, etc.). At the same time, the flow control unit 13 can also distribute water to different branches, for example, when heating is not required, part of the water is directly distributed to the water outlet module as output, or when cold water and hot water need to be mixed to adjust the water temperature, the corresponding distribution operation is performed, and the present application does not limit this.

[0104] In one possible implementation, Fig.10 As shown, the flow control unit 13 includes a flow control valve 131 and an on-off valve 132, the first end of the flow control valve 131 is connected to the water inlet 11, the second end of the flow control valve 131 is connected to the first end of the on-off valve 132, and the second end of the on-off valve 132 is connected to the water outlet module 30.

[0105] It should be noted that the present application uses the combination of the flow control valve 131 and the on-off valve 132 as an example for explanation, which does not limit the present application. When the system is in standby mode or in some situations where water is not required to flow out, the on-off valve 132 is closed to prevent unnecessary flow of water in the pipeline, thereby reducing heat loss and water resource waste. When water is needed, after the on-off valve 132 is opened, the flow control valve 131 can accurately control the flow, avoid excessive water consumption due to excessive flow, and achieve the purpose of energy saving.

[0106] The on-off valve 132 and the flow control valve 131 can also prevent water hammer to a certain extent. Water hammer is a pressure wave caused by a sudden change in water flow (such as sudden closing of a valve), which may cause damage to pipes and equipment. When it is necessary to stop the water flow quickly, first close the flow control valve 131, gradually reduce the flow, and then close the on-off valve 132, which can effectively reduce the water hammer phenomenon, extend the service life of equipment and pipes, and improve the safety of the system.

[0107] Optionally, in the above embodiment, only the flow control valve 131 may be used to accurately adjust the flow of water, so as to avoid wasting water resources or causing the water temperature to drop too quickly due to excessive flow. Optionally, in the above embodiment, only the on-off valve 132 may be used to control the on and off of the water path, so as to simply and quickly achieve control of the water path, and this application does not limit this.

[0108] In one possible implementation, Fig.10 As shown, the flow meter unit 12 includes a flow meter 121 , a first end of the flow meter 121 is connected to the water inlet 11 , and a second end of the flow meter 121 is connected to the heat exchange unit 21 .

[0109] The flow meter 121 can measure the water flow entering the system, which helps the system determine the initial water inflow situation. If the water inflow does not meet expectations, it can indicate that the system may have a clogged water inlet pipe, insufficient water pressure, or other problems. Through the measurement of the flow meter 121, the system can perform preliminary troubleshooting at the startup stage to ensure subsequent normal operation.

[0110] Optionally, the data provided by the flow meter 121 can help the system make water flow distribution decisions. Furthermore, the data of the flow meter 121 can work in conjunction with other components (such as the flow control valve 131 and the NTC thermistor, etc.). For example, when the flow meter 121 detects a large water inflow and the NTC thermistor detects a slightly lower water temperature, the system can control the flow control valve 131 to appropriately increase the water inflow and adjust the heating power to quickly increase the water temperature, thereby achieving accurate supply.

[0111] See also Fig.11 As shown, Fig.11 A schematic diagram of a water circuit structure of a refrigeration module 40 provided in an embodiment of the present invention. The refrigeration module 40 includes a refrigeration unit 41 and a cold water pump 42, the water inlet of the refrigeration unit 41 is connected to the second end of the on-off valve 132, and the water outlet of the refrigeration unit 41 is connected to the water outlet module 30 through the cold water pump 42;

[0112] The refrigeration unit 41 is used to refrigerate the water entering the refrigeration module 40;

[0113] The cold water pump 42 is used to output the refrigerated water and / or the water entering the refrigeration module 40 to the water outlet module 30 .

[0114] It should be noted that the refrigeration unit 41 can refrigerate the water entering the refrigeration module 40. For example, when a user needs cold water, water flows into the refrigeration unit 41 from the second end of the on-off valve 132, and the refrigeration unit 41 can reduce the temperature of the water through its own refrigeration mechanism (such as compressor refrigeration, semiconductor refrigeration, etc.), thereby meeting the user's demand for cold water.

[0115] The cold water pump 42 plays a role in power transmission in the refrigeration module 40, and can output the refrigerated water to the water outlet module 30. Optionally, when the water does not need to be refrigerated, the cold water pump 42 can also directly transport the water entering the refrigeration module 40 to the water outlet module 30. For example, when the device is in energy-saving mode or the user only needs water at room temperature, the cold water pump 42 can simply transfer the unrefrigerated water. The normal circulation and supply of water in the entire water system of the device is guaranteed, so that the device can flexibly respond to the water temperature requirements of different users.

[0116] In one possible implementation, Fig.11 As shown, the refrigeration module 40 also includes a one-way valve 43 (such as called a third one-way valve 43 ), a first end of the third one-way valve 43 is connected to the cold water pump 42 , and a second end of the third one-way valve 43 is connected to the water outlet module 30 .

[0117] Among them, the third one-way valve 43 can ensure that water flows from the cold water pump 42 to the water outlet module 30, but prevents water from flowing back from the water outlet module 30 to the cold water pump 42. The third one-way valve 43 can prevent the backflow of water to protect the cold water pump 42 and the refrigeration unit 41 in the refrigeration module 40. The backflow of water may generate reverse pressure on the cold water pump 42, causing the impeller of the cold water pump 42 to reverse, which may damage the motor and mechanical parts of the cold water pump 42. The third one-way valve 43 also helps to stabilize the water pressure and water flow of the water outlet module 30. By limiting the reverse flow of water, it can be ensured that the water received by the water outlet module 30 is supplied in accordance with the normal water flow direction and pressure designed for the equipment.

[0118] In one possible implementation, Fig.11 As shown, the refrigeration module 40 also includes a one-way valve 44 (such as referred to as a fourth one-way valve 44), a first end of the fourth one-way valve 44 is connected to the refrigeration unit 41, and a second end of the fourth one-way valve 44 is connected to the exhaust unit 24 of the heating module 20.

[0119] Among them, the fourth one-way valve 44 can prevent hot water from flowing back from the exhaust unit 24 of the heating module 20 into the refrigeration unit 41. During the operation of the equipment, the heating module 20 may generate high-temperature water or steam, and exhaust and other operations are performed through the exhaust unit 24. When the pressure on the side of the heating module 20 is higher than the pressure on the side of the refrigeration unit 41 (for example, a higher pressure is generated during the heating process), the hot water or steam may enter the refrigeration unit 41 along the pipeline, which may cause damage to the refrigeration unit 41. The entry of high-temperature water or steam may destroy its internal refrigeration structure, such as damaging the refrigeration pipeline and affecting the performance of the refrigerant.

[0120] In one possible implementation, Fig.11 As shown, the refrigeration module 40 also includes a two-way valve 45 (such as called a second two-way valve 45), the first end of the second two-way valve 45 is connected to the refrigeration unit 41, and the second end of the second two-way valve 45 is connected to the on-off valve 132 of the water inlet module 10.

[0121] When it is detected that the water level in the refrigeration unit 41 is low or a new water source is needed, the second two-way valve 45 can open the passage from the on-off valve 132 to the refrigeration unit 41, so that water can be smoothly added to the refrigeration unit 41 to ensure that the refrigeration unit 41 always has enough water for refrigeration and maintain the normal refrigeration function of the equipment.

[0122] When the sterilization program is started, the second two-way valve 45 can introduce water containing sterilization components (such as water treated with ultraviolet light, water with disinfectant added, etc.) from the on-off valve 132 of the water inlet module 10 into the refrigeration unit 41, and the present application does not impose any restrictions on this.

[0123] In one possible implementation, Fig.11 As shown, the refrigeration module 40 also includes a three-way valve 46 (such as called a second three-way valve 46), a first end of the second three-way valve 46 is connected to the refrigeration unit 41, a second end of the second three-way valve 46 is connected to the heating energy storage unit 22 and the heat exchange unit 21 of the heating module 20, and a third end of the second three-way valve 46 is connected to the first three-way valve 51 of the drainage module 50.

[0124] The second three-way valve 46 can be used to achieve various water flow directions, making the water system of the water supply device 1 more flexible and efficient.

[0125] The water supply device 1 provided in the present application can achieve precise temperature control and provide a variety of water temperature options through multiple types of control valves, water temperature detectors 32 and refrigeration modules 40, and can be precisely adjusted in water temperature control; through the cooperation of the heating energy storage unit 22, the heat exchange unit 21 and the instant heating unit 23, rapid heating, heat storage and heat recovery and reuse can be achieved, and energy efficiency is high in energy utilization; multiple one-way valves can prevent backflow pollution, ensure water hygiene and safety, maintain stable pressure balance, and improve user experience and equipment operation efficiency as a whole, with high system reliability; the heating module, the refrigeration module, and the water inlet module share the water outlet waterway in the water outlet module, which can reduce consumables and improve the diversity and practicality of the waterway function; the coordinated operation of each component can not only ensure the stable output of water that meets the preset temperature, improve user experience, but also improve energy utilization efficiency, and can also use the wastewater outlet to maintain the system cleanliness and extend the service life of the system.
