[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 1This is a structural schematic diagram 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 and a control module 50; 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 cooling module 40, and the water inlet module 10 is also connected to the water outlet module 30, so as to control 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 the heat exchange unit 21, store the heat exchange medium used for heating, and heat the water output from the heat exchange unit 21 through the instant heating unit 23 and then transmit it to the water outlet module 30 and / or transmit the water output from the heat exchange unit 21 to the water outlet module 30 through the instant heating unit 23;

[0049] The water outlet module 30 is connected to the heating module 20 and / or the cooling module 40, and the water outlet module 30 is connected to the water inlet module 10, and is used to output water meeting a preset temperature;

[0050] The control module 50 is connected to the water inlet module 10 and the water outlet module 30, and is also connected to the heating module 20 and / or the refrigeration module 40, for controlling the water inlet module 10, the water outlet module 30 and the heating module 20 and / or the refrigeration module 40 to operate.

[0051] It should be noted that the water supply device 1 can be used to provide drinking water. Since the hot water and the flow-increasing waterway 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 waterway can use relatively small diameter pipes, such as 2-branch pipes. The usage of the normal temperature and cold water waterway 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.

[0052] In this embodiment, the water output by the heat exchange unit 21 is heated by the instant heating unit 23 and then transmitted to the water outlet module 30 and / or the water output by the heat exchange unit 21 is transmitted to the water outlet module 30 by the instant heating unit 23. When the user needs water, water at a preset temperature can be provided to the user quickly and efficiently, thereby improving the user experience.

[0053] In this embodiment, the water inlet amount of the water system of the water supply device is first controlled by the water inlet module 10, and the water entering the water system of the water supply device is heated by the heating module 20, and the water obtained after heating is stored. Then, the water temperature is detected by the water outlet module 30, and water meeting a preset temperature is output. The water inlet module 10, the heating module 20, and the water outlet module 30 are further controlled by the control module 5040 to work, so as to achieve stable heating of the water entering the water system of the water supply device, and effectively perform temperature feedback and real-time adjustment mechanism, so as to achieve the purpose of more stably supplying water meeting the preset temperature.

[0054] See also Figure 2 As shown, Figure 2 A schematic diagram of a water path 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. 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. The heating energy storage unit 22 is connected to the refrigeration module 40 through a bridge water path.

[0055] The heat exchange unit 21 is used to heat the water entering the heating module 20;

[0056] 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;

[0057] 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;

[0058] The refrigeration module 40 is also used to replenish water to the heating energy storage unit 22 through the bridging water path.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] See also Figure 3 As shown, Figure 3 The schematic diagram of the water circuit structure of another heating module 20 provided in an embodiment of the present invention. The heating module 20 also includes a circulating water pump 25, which is connected to the heating energy storage unit 22 and the heat exchange module 21, wherein:

[0064] 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 .

[0065] See also Figure 4 As shown, Figure 4 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. 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.

[0066] A flow meter unit 12, used to measure the water flow to the heating module 20;

[0067] 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 .

[0068] 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.

[0069] The flow control unit 13 can control the flow of water entering the water outlet module 30 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 30 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.

[0070] In one possible implementation, Figure 4 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] In one possible implementation, Figure 4 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 .

[0075] 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.

[0076] 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.

[0077] In one possible implementation, Figure 4 As shown, Figure 4 , a schematic diagram of a 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 the first two-way valve 31), a negative temperature coefficient (Negative Temperature Coefficient, NTC) thermistor 32, a one-way valve 33 (such as called the first 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 60 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 first one-way valve 33, and the second end of the first one-way valve 33 is connected to the water outlet 34, wherein,

[0078] NTC thermistor 32, used to measure the temperature of the delivered water;

[0079] The water outlet 34 is used to output water meeting a preset temperature.

[0080] 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.

[0081] 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 60, 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.

[0082] 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 60. 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 60 through the first two-way valve 31.

[0083] 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 30 and prevent the second type of liquid from entering from the outside.

[0084] 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.

[0085] 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.

[0086] 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 50 will keep the wastewater waterway of the drainage module 60 closed to provide water with the required temperature for users.

[0087] 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.

[0088] See also Figure 5 As shown, Figure 5 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 water inlet module 10, and the water outlet of the refrigeration unit 41 is connected to the water outlet module 30 through the cold water pump 42;

[0089] A refrigeration unit 41, used for refrigerating water entering the refrigeration module 40;

[0090] 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 .

[0091] 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.

[0092] The cold water pump 42 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 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.

[0093] In a possible implementation, the refrigeration unit 41 further includes a fourth control valve, a fifth control valve and a sixth control valve, the first water path interface of the fourth control valve is connected to the water inlet module 10, the second water path interface of the fourth control valve is connected to the water inlet interface of the refrigeration unit 41 and the first water path interface of the fifth control valve, the second water path interface of the fifth control valve is connected to the heating energy storage unit 22 through a bridging water path, the first water path interface of the sixth control valve is connected to the water outlet interface of the cold water pump 42, and the second water path interface of the sixth control valve is connected to the water outlet module 30;

[0094] A fourth control valve, used to control water replenishment of the refrigeration unit 41 and / or sterilize water entering the refrigeration unit 41;

[0095] A fifth control valve, used for controlling water replenishment when replenishing water to the heating energy storage unit 22;

[0096] The sixth control valve is used to control the water flow from the refrigeration unit 41 to the water outlet module 30.

[0097] Among them, the fourth control valve can be a two-way valve 45 (such as called the second two-way valve 45). When it is detected that the water level in the refrigeration unit 41 is low or a new water source needs to be added, 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.

[0098] 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.

[0099] The fifth control valve may be a one-way valve 43 (such as a second one-way valve 43), wherein the second one-way valve 43 may 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 device, the heating module 20 may generate high-temperature water or steam, and exhaust the air through the exhaust unit 24. When the pressure on the heating module 20 side is higher than the pressure on the refrigeration unit 41 side (for example, a higher pressure is generated during the heating process), the hot water or steam may flow into the refrigeration unit 41 along the pipeline, which may damage the refrigeration unit 41. The entry of high-temperature water or steam may destroy the internal refrigeration structure, such as damaging the refrigeration pipeline and affecting the performance of the refrigerant.

[0100] 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 second one-way valve 43. 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 second one-way valve 43, and the present application does not limit this.

[0101] 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.

[0102] The sixth control valve may be a one-way valve 44 (such as referred to as the third one-way valve 44). The third one-way valve 44 may 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 44 may 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 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.

[0103] See also Figure 6 As shown, Figure 6 A schematic diagram of the water circuit structure of another refrigeration module 40 provided in an embodiment of the present invention. The refrigeration unit 41 also includes a fourth control valve, a fifth control valve and a sixth control valve, the first water circuit interface of the fourth control valve is connected to the water inlet module 10, the second water circuit interface of the fourth control valve is connected to the water inlet interface of the refrigeration unit 41, the first water circuit interface of the fifth control valve is connected to the refrigeration unit 41, the second water circuit interface of the fifth control valve is connected to the heating energy storage unit 22 through a bridging water circuit, the first water circuit interface of the sixth control valve is connected to the water outlet interface of the cold water pump 42, and the second water circuit interface of the sixth control valve is connected to the water outlet module 30.

[0104] pass Figure 6 In the water circuit structure shown, the cooling module 40 can be connected to the heating and heat storage unit 22 of the heating module 20 through the bridge water circuit by the fifth control valve, so that the heating and heat storage unit 22 can be more conveniently replenished with water without being limited by the water level of the cooling module 40. Optionally, the fifth control valve can be a one-way valve 43, which is not limited in the present application.

[0105] 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.

[0106] See also Figure 7 As shown, Figure 7 A 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 includes a drainage module 60, which is connected to the water outlet module 30, the refrigeration module 40, and the heating module 20, and is used to assist the water circuit reflux of the heating module 20 and the refrigeration module 40, and to discharge waste water from the heating module 20, the water outlet module 30, and the refrigeration module 40.

[0107] 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 draining the wastewater out of the system through the drainage module 60, 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.

[0108] In one possible implementation, Figure 7 As shown, the drainage module 60 includes a first control valve, a wastewater pump and a drainage component, wherein the drainage component is connected to the wastewater pump and the first control valve;

[0109] The first control valve is used to control the wastewater of the water outlet module 30 transmitted to the drainage component by the wastewater pump; to control the wastewater of the heating module 20 transmitted to the drainage component by the wastewater pump; and to control the wastewater of the refrigeration module 40 transmitted to the drainage component by the wastewater pump;

[0110] A wastewater pump, used to transfer wastewater from the heating module 20, wastewater from the refrigeration module 40, and wastewater from the water outlet module 30 to a drainage component;

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

[0112] The first control valve may be a one-way valve 61 (such as a fourth one-way valve 61). The fourth one-way valve 61 may be used to control the wastewater flowing from the water outlet module 30 to the drainage component 63; to control the wastewater of the water outlet module 30 transmitted to the drainage component by the wastewater pump; to control the wastewater of the heating module 20 transmitted to the drainage component by the wastewater pump; and to control the wastewater of the refrigeration module 40 transmitted to the drainage component by the wastewater pump.

[0113] 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 meets the water temperature standard, thereby ensuring that the user can use water at the appropriate temperature.

[0114] 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.

[0115] The drainage component 63 may be a component for discharging water (such as waste water, etc.). 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.

[0116] 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.

[0117] 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.

[0118] See also Figure 8 As shown, Figure 8 A schematic diagram of a waterway structure of another drainage module 60 provided in an embodiment of the present invention. The drainage module 60 includes a second control valve, a third control valve, a wastewater pump and a drainage component, wherein the drainage component is connected to the wastewater pump, the first waterway interface of the second control valve is connected to the water outlet module 30 through the waterway, the second waterway interface of the second control valve is connected to the third waterway interface of the third control valve through the waterway, and the third waterway interface of the second control valve is connected to the wastewater pump through the waterway;

[0119] The second water channel interface of the third control valve is connected to the refrigeration module 40 through the water channel, and the first water channel interface of the third control valve is connected to the heating module 20 through the water channel.

[0120] Among them, the second control valve can be a three-way valve 64 (such as called the first three-way valve 64). The first three-way valve 64 can distribute the water flow to three different directions, and the first three-way valve 64 can also switch or mix the water flow between different waterway branches. The first three-way valve 64 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 64 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.

[0121] The third control valve may be a three-way valve 65 (eg, referred to as a second three-way valve 65 ). The second three-way valve 65 may be used to achieve a variety of water flow directions, making the water system of the water supply device 1 more flexible and efficient.

[0122] See also Fig. 9 As shown, Fig. 9 A schematic diagram of an embodiment of the present invention providing a method of replenishing air through a water outlet component 301 of a water outlet module 30. 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 component of the water outlet module 30;

[0123] The exhaust unit 24 is used to replenish air to the wastewater pump in the drainage module 60 through the water outlet component when draining wastewater in the water outlet module 30; to replenish air to the wastewater pump in the drainage module 60 through the water outlet component when draining wastewater in the refrigeration module 40; and to replenish air to the wastewater pump in the drainage module 60 through the water outlet component when draining wastewater in the heating energy storage unit 22.

[0124] 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 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. 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 62 can work continuously and stably, and helping to improve the drainage efficiency of the wastewater pump 62.

[0125] See also Fig.10 As shown, Fig.10 A schematic diagram of an embodiment of the present invention providing air replenishment through the air inlet 302 of the water outlet module 30. The heating module 20 further includes an exhaust unit 24, a first end of the exhaust unit is connected to the heating energy storage unit 22, and a second end of the exhaust unit 24 is connected to the air inlet 302 of the water outlet module 30;

[0126] The exhaust unit 24 is used to replenish air to the wastewater pump in the drainage module 60 through the air inlet when draining the wastewater in the water outlet module 30; replenish air to the wastewater pump in the drainage module 60 through the air inlet when draining the wastewater in the refrigeration module 40; replenish air to the wastewater pump in the drainage module 60 through the air inlet when draining the wastewater in the heating energy storage unit 22

[0127] The wastewater pump 52 can be supplied with air through the air inlet 302 of the water outlet module 30. Specifically, a one-way valve can be installed at the air inlet 302 to evacuate the water in the pipeline. Optionally, the air inlet 302 and the one-way valve can be implemented by a compressible water bag.

[0128] The water supply device 1 provided in the present application can achieve precise temperature control and provide a variety of water temperature options through various types of control valves, NTC thermistors and refrigeration modules 40, and can be precisely adjusted in water temperature control; through the cooperation of heat storage tanks, heat exchangers and thick film instant heating units 23, rapid heating, heat storage and heat recovery and reuse can be achieved, and energy efficiency is high; through multiple one-way valves, backflow pollution can be prevented, water hygiene and safety can be guaranteed, and pressure balance can be maintained to maintain a stable balance, thereby improving the user experience and equipment operating efficiency as a whole, and the system reliability is high; the coordinated operation of various components 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 clean and extend the service life of the system.
