[0043] 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.

[0044] See also Figure 1A As shown, Figure 1A This is 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 includes: a water inlet module 10, a heating module 20, a water outlet module 30, a cooling module 40 and a control module 50;

[0045] The water inlet module 10 is connected to the heating module 20, the cooling module 40, and the water outlet module 30, and is used to control the amount of water entering the water supply device 1;

[0046] 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;

[0047] The water outlet module 30 is connected to the heating module 20, the cooling module 40 and the water inlet module 10, and is used to output water meeting a preset temperature;

[0048] The refrigeration module 40 is connected to the heating and heat storage unit 22 of the heating module 20 through a bridging water path, and the water inlet module 10 replenishes water to the heating and heat storage unit 22 through the bridging water path, or the refrigeration module 40 replenishes water to the heating and heat storage unit 22 through the bridging water path;

[0049] The control module 50 is connected to the water inlet module 10 , the heating module 20 , the water outlet module 30 , and the refrigeration module 40 , and is used to control the water inlet module 10 , the heating module 20 , and the water outlet module 30 to work.

[0050] It should be noted that, 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, and this application does not limit this.

[0051] 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. Then, the water that meets the preset temperature is output through the water outlet module 30, and the heating heat storage unit 22 can be replenished with water through the bridging water path between the cooling module 40 and the heating heat storage unit 22 of the heating module 20. For example, the water inlet module 10 can replenish the heating heat storage unit 22 with water through the bridging water path, or the cooling module 40 can replenish the heating heat storage unit 22 with water through the bridging water path. The water inlet module 10, the heating module 20, the water outlet module 30 and the cooling module 40 are further controlled by the control module 50 to work, so as to achieve better water replenishment of the heating heat storage unit 22 and stably heat the water entering the water supply device 1, thereby achieving the purpose of more stably supplying water that meets the preset temperature.

[0052] In a possible implementation, Figure 1B As shown, Figure 1B A structural schematic diagram of another water supply device 1 provided in an embodiment of the present invention, wherein the bridging water path between the refrigeration module 40 and the heating heat storage unit 22 of the heating module 20 includes a one-way valve 41 (such as referred to as a first one-way valve 41), and the first one-way valve 41 is used to control the refrigeration module 40 or the water inlet module 10 to replenish water to the heating heat storage unit 22.

[0053] Among them, the first one-way valve 41 can prevent hot water from flowing back from the exhaust unit 24 of the heating module 20 into the refrigeration unit 42. 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 42 (for example, a higher pressure is generated during the heating process), the hot water or steam may enter the refrigeration unit 42 along the pipeline, which may cause damage to the refrigeration unit 42. 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.

[0054] It is understandable that when the water in the refrigeration module 40 is sufficient, such as exceeding the maximum water level of the refrigeration module 40, the refrigeration module 40 can replenish water to the heating and heat storage unit 22 of the heating module 20 through the first one-way valve 41. Optionally, when the water in the refrigeration module 40 is sufficient, the water in the water inlet module 10 will not be able to flow into the refrigeration module 40. At this time, the water inlet module 10 can replenish water to the heating and heat storage unit 22 of the heating module 20 through the first one-way valve 41, and the present application does not limit this.

[0055] By replenishing water to the heating and heat storage unit 22 through the bridge water path, the normal operation of the heating and heat storage unit 22 can be maintained. During use, as the water in the heating and heat storage unit 22 continues to decrease, the water level will gradually decrease. By replenishing water from the refrigeration module 40 or the water inlet module 10, the water level of the heating and heat storage unit 22 can be maintained at a suitable level to ensure that there is enough water for heating and storage, thereby ensuring that hot water can be continuously provided to users.

[0056] In a possible implementation, Figure 1C As shown, Figure 1C A schematic diagram of the structure of another water supply device 1 provided in an embodiment of the present invention, Figure 1C The cooling module 40 can be connected to the heating and heat storage unit 22 of the heating module 20, so that the heating and heat storage unit 22 can be replenished with water more conveniently without being limited by the water level of the cooling module 40. Figure 1C The one-way valve 41 shown is connected to the heating and heat storage unit 22 of the heating module 20, and the present application does not impose any limitation on this.

[0057] It is understandable that the water replenishment operation can also help adjust the water temperature in the heating and thermal storage unit 22. For example, if the water temperature in the heating and thermal storage unit 22 is too high, an appropriate amount of water with a lower temperature can be added to reduce the water temperature to a suitable range, thereby enhancing the stability of the water temperature in the heating and thermal storage unit 22, reducing water temperature fluctuations, and providing users with a more stable hot water supply.

[0058] See also Figure 2 As shown, Figure 2 A schematic diagram of a water circuit structure of a heating module 20 provided in an embodiment of the present invention. 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, and the instant heating module 23 is connected to the water outlet module 30 and the heating energy storage unit 22;

[0059] The heat exchange unit 21 is used to heat the water entering the heating module 20;

[0060] The heating energy storage unit 22 is used to store water entering the heating energy storage unit 22;

[0061] The instant heating unit 23 is used to heat the water entering the heating energy storage unit 23 and / or the water output from the heat exchange unit 21 .

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] In one possible implementation, Figure 2 As shown, the heating module 20 further includes an exhaust unit 24, and the exhaust unit 24 is connected to the heating energy storage unit 22, wherein:

[0067] The exhaust unit 24 is used to exhaust the heating energy storage unit 22 through the air hole 301 of the water outlet module 30 .

[0068] 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.

[0069] In a possible implementation, 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:

[0070] 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 .

[0071] In a possible implementation, the heating module 20 also includes a three-way valve 26 (such as referred to as a first three-way valve 26). The first end of the first three-way valve 26 is connected to the circulating water pump 25, the second end of the first three-way valve 26 is connected to the heat exchange unit 21, and the third end of the first three-way valve 26 is connected to the instant heating unit 23.

[0072] Among them, the first three-way valve 26 can provide a variety of water flow path options. When the user needs to quickly obtain hot water, the first three-way valve 26 can be controlled to direct the water to the instant heating unit 23, and the instant heating unit 23 can quickly heat the water to meet the user's immediate hot water needs. When the water supply device 1 is in an energy-saving or preheating mode, the first three-way valve 26 can direct the water to the heat exchange unit 21, and the heat exchange unit 21 can achieve temperature increase by exchanging heat with other media (such as already heated water or other heat sources) to provide hot water in a more energy-efficient manner.

[0073] See also Figure 3 As shown, Figure 3 The schematic diagram of the water path structure 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. The water inlet 11 is connected to the flow meter unit 12 and the flow control unit 13. The flow control unit 13 is connected to the water outlet module 30 and the refrigeration module 40.

[0074] The flow meter unit 12 is used to measure the water flow to the heating module 20;

[0075] 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 .

[0076] 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.

[0077] 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 demand (such as the user's demand for hot water output, the safety limit 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.

[0078] In one possible implementation, Figure 3 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.

[0079] 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.

[0080] 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.

[0081] Optionally, in the above embodiment, only the flow control valve 131 can be used to accurately adjust the flow rate of the water flow, 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 can 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 the present application does not limit this. Optionally, in the above embodiment, a pressure relief valve and a water pump can be combined to achieve the purpose of accurately adjusting the flow rate of the water flow, and the present application does not limit this.

[0082] In one possible implementation, Figure 3 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 .

[0083] 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.

[0084] 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.

[0085] In one possible implementation, Figure 3 As shown, Figure 3 , a schematic diagram of the water circuit structure of a water outlet module 30 is exemplarily shown. The water outlet module 30 includes a two-way valve 31 (such as called a first two-way valve 31), a negative temperature coefficient (Negative Temperature Coefficient, NTC) thermistor 32, a one-way valve 33 (such as called a second one-way valve 33) and a water outlet 34, wherein the first end of the first two-way valve 31 is connected to the instant heating unit 23 and the water inlet module 10, the second end of the first two-way valve 31 is connected to the drainage module 50 and the first end of the NTC thermistor 32; the first end of the NTC thermistor 32 is connected to the refrigeration module 40; the second end of the NTC thermistor 32 is connected to the first end of the second one-way valve 33, and the second end of the second one-way valve 33 is connected to the water outlet 34, wherein,

[0086] NTC thermistor 32, used to measure the temperature of the delivered water;

[0087] The water outlet 34 is used to output water meeting a preset temperature.

[0088] 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.

[0089] 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.

[0090] Optionally, the exhaust unit 24 is 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 adverse effects of gas accumulation on the system.

[0091] 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.

[0092] In a possible implementation, the second 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.

[0093] 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.

[0094] The second 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 second 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.

[0095] 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.

[0096] 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.

[0097] See also Figure 4 As shown, Figure 4 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 42 and a cold water pump 43, the water inlet of the refrigeration unit 42 is connected to the second end of the on-off valve 132, and the water outlet of the refrigeration unit 42 is connected to the water outlet module 30 through the cold water pump 43;

[0098] The refrigeration unit 42 is used to refrigerate the water entering the refrigeration module 40;

[0099] The cold water pump 43 is used to output the refrigerated water and / or the water entering the refrigeration module 40 to the water outlet module 30 .

[0100] It should be noted that the refrigeration unit 42 can refrigerate the water entering the refrigeration module 40. For example, when a user needs cold water, water flows into the refrigeration unit 42 from the second end of the on-off valve 132, and the refrigeration unit 42 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.

[0101] The cold water pump 43 can play 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 43 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 43 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.

[0102] In a possible implementation, the refrigeration module 40 also includes a one-way valve 44 (such as a third one-way valve 44 ), a first end of the third one-way valve 44 is connected to the cold water pump 43 , and a second end of the third one-way valve 44 is connected to the water outlet module 30 .

[0103] Among them, the third one-way valve 44 can ensure that water flows from the cold water pump 43 to the water outlet module 30, but prevents water from flowing back from the water outlet module 30 to the cold water pump 43. The third one-way valve 44 can prevent the backflow of water to protect the cold water pump 43 and the refrigeration unit 42 in the refrigeration module 40. The backflow of water may generate reverse pressure on the cold water pump 43, causing the impeller of the cold water pump 43 to reverse, which may damage the motor and mechanical parts of the cold water pump 43. The third one-way valve 44 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.

[0104] In one possible implementation, the refrigeration module 40 also includes a two-way valve 45 (such as a second two-way valve 45), the first end of the second two-way valve 45 is connected to the refrigeration unit 42, 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.

[0105] When it is detected that the water level in the refrigeration unit 42 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 42, so that water can be smoothly added to the refrigeration unit 42 to ensure that the refrigeration unit 42 always has enough water for refrigeration and maintain the normal refrigeration function of the equipment.

[0106] When the sterilization program is started, the second two-way valve 45 can introduce water containing sterilization components (such as water treated with ultraviolet disinfection, water with added disinfectant, etc.) from the on-off valve 132 of the water inlet module 10 into the refrigeration unit 42, and the present application does not impose any restrictions on this.

[0107] See also Figure 5 As shown, Figure 5A schematic diagram of a water circuit structure of another water supply device 1 provided in an embodiment of the present invention. The water supply device 1 further includes a drainage module 60, and the drainage module 60 is connected to the water outlet module 30, the heating module 20, and the refrigeration module 40;

[0108] The drainage module 60 includes a first control valve, a wastewater pump 62 and a drainage component 63, wherein the drainage component 63 is connected to the wastewater pump 62 and the first control valve;

[0109] The first control valve is used to control the waste water flowing from the water outlet module 30 to the drainage component 63;

[0110] The wastewater pump 62 is used to transfer the wastewater of the heating module 20 and the wastewater of the refrigeration module 40 to the drainage component 63;

[0111] The drainage component 63 is used to discharge waste water from the heating module 20 , waste water from the cooling module 40 , and waste water from the water outlet module 30 .

[0112] The drainage component 63 may be a component for discharging water (such as waste water). The drainage component 63 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.

[0113] In one possible implementation, Figure 5 As shown, the first control valve can be a three-way valve 61 (such as called the second three-way valve 61), the first water channel interface of the second three-way valve 61 is connected to the water outlet module 30 through the water channel, the second water channel interface of the second three-way valve 61 is connected to the heating module 10 and the refrigeration module 40 through the water channel, and the third water channel interface of the second three-way valve 61 is connected to the wastewater pump 62 through the water channel.

[0114] Among them, the second three-way valve 61 can distribute the water flow to three different directions. The second three-way valve 61 can switch between different waterway branches or mix water flows, etc. The second three-way valve 61 can not only regulate the water flow path, but also work in conjunction with other modules. For example, when the water temperature does not meet the preset water temperature, the second three-way valve 61 can change the water flow path to guide the substandard water to one end of the wastewater pump 62 connected to it, so as to prepare for the subsequent reflux and reheating of the water.

[0115] It should be noted that the wastewater pump 62 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 62 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 second three-way valve 61, so that the water can return to the heating module 20 for reheating, so as to ensure that the final output water temperature meets the standard, thereby ensuring that the user can use water at the appropriate temperature.

[0116] The reflux power provided by the wastewater pump 62 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 flowing out directly for use 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.

[0117] In one possible implementation, Figure 6 As shown, Figure 6 The schematic diagram of replenishing air through the air hole 301 of the water outlet module 30 is exemplarily shown. The exhaust unit 24 is also used to replenish air to the wastewater pump 62 in the drainage module 60 through the air hole 301 of the water outlet module 30 when draining wastewater in the water outlet module 30.

[0118] Among them, the wastewater pump 52 can be supplied with air through the air hole 301 of the water outlet module 30. Specifically, a one-way valve can be installed at the air hole 301 to evacuate the water in the pipeline. Optionally, the air hole 301 and the one-way valve mode can be realized by a compressible water bag.

[0119] In one possible implementation, Figure 7 As shown, Figure 7 The schematic diagram of air replenishment through the air hole 302 of the water outlet module 30 is exemplarily shown. The exhaust unit 24 is also used to replenish air to the wastewater pump 62 in the drainage module 60 through the water outlet component 302 of the water outlet module 30 when exhausting the wastewater in the water outlet module 30; replenish air to the wastewater pump 62 in the drainage module 60 through the water outlet component 302 of the water outlet module 30 when exhausting the wastewater in the refrigeration module 40; replenish air to the wastewater pump 62 in the drainage module 60 through the water outlet component 302 of the water outlet module 30 when draining the wastewater in the heating energy storage unit 22.

[0120] Among them, the water outlet component 302 can be a component that provides water (to the user). The water outlet component 302 can be a faucet, a shower, a nozzle or a water outlet, etc. Taking the water outlet component 302 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 62), and this application does not limit this. When the wastewater pump 62 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. Air replenishment 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 62 can work continuously and stably, and helping to improve the drainage efficiency of the wastewater pump 62.

[0121] In one possible implementation, see Figure 8 As shown, Figure 8 A schematic diagram of a water circuit structure of another refrigeration module 40 provided in an embodiment of the present invention. The refrigeration module 40 further includes a three-way valve 46 (such as a third three-way valve 46), a first end of the third three-way valve 46 is connected to the refrigeration unit 42, a second end of the third 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 third three-way valve 46 is connected to the first three-way valve 61 of the drainage module 60.

[0122] The third 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.

[0123] In one possible implementation, Figure 8 As shown, the heating module 20 further includes a water pump 27 , a first end of the water pump 27 is connected to the instant heating unit 23 , and a second end of the water pump 27 is connected to the heating energy storage unit 22 .

[0124] The water pump 27 is mainly responsible for transporting water between the instant heating unit 23 and the heating energy storage unit 22 in the heating module 20. After the instant heating unit 23 quickly heats the water, the water pump 27 can transport the heated water to the heating energy storage unit 22 for storage for subsequent use, which helps to maintain the water circulation inside the heating module 20.

[0125] The water supply device 1 provided in the present application can be precisely adjusted in terms of water temperature control. Through various types of control valves and NTC thermistors, precise temperature control can be achieved and a variety of water temperature options can be provided. In terms of energy utilization, it is efficient and energy-saving. Through the cooperation of heat storage tanks, heat exchangers and thick film instant heating units, rapid heating, heat storage and heat recovery and reuse can be achieved. The system has high reliability. Multiple one-way valves can prevent backflow pollution, ensure water hygiene and safety, and maintain stable pressure balance, thereby improving user experience and equipment operation efficiency as a whole. Moreover, the heating heat storage unit 22 can be replenished with water through the bridging water path between the cooling module 40 and the heating heat storage unit 22 of the heating module 20. For example, the water inlet module 10 can replenish the heating heat storage unit 22 with water through the bridging water path, or the cooling module 40 can replenish the heating heat storage unit 22 with water through the bridging water path, so that the heating heat storage unit 22 can be better replenished with water and the water entering the water supply device 1 can be stably heated, thereby achieving the purpose of more stably supplying water that meets the preset temperature.
