[0040] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] Please refer to Figure 1 as shown, Figure 1 A structure schematic view of a water supply device 1 provided by an embodiment of the present application is shown in the figure, which comprises: a water inlet module 10, a water outlet module 30, a control module 40, a refrigeration module 50 and / or a heating module 20.

[0042] The water inlet module 10 is in communication with the heating module 20 and the refrigeration module 50, and is used to control the water inlet amount of the water supply device;

[0043] The heating module 20 is used to heat the water entering the heating module 20 by a heating unit in the heating module 20, and store the water for heating.

[0044] The water outlet module 30 is in communication with the heating module 20, the refrigeration module 50 and the water inlet module 10, or the water outlet module 30 is in communication with the heating module 20 and the refrigeration module 50, wherein the water outlet module 30 is used to output water meeting a preset temperature.

[0045] The control module 40 is electrically connected with the water inlet module 10, the heating module 20, the water outlet module 30 and the refrigeration module 50.

[0046] It should be noted that the hot water and the flow water path have relatively low requirements on the flow rate, in order to save space and material cost while meeting the functions, the hot water and the flow water path can adopt a pipe with a relatively small pipe diameter, such as a 2-inch pipe. The usage amount of the normal temperature water and the cold water path can be relatively large, and the normal temperature water and the cold water can adopt a pipe with a relatively large pipe diameter, such as a 3-inch pipe, which is not limited in the present application.

[0047] The embodiment first controls the water inflow of the water supply device water system through the water inflow module 10, heats the water entering the water system of the water supply device through the heating module 20, stores the water after heating, then detects the water temperature through the water outlet module 30 and outputs the water meeting the preset temperature, and further controls the water inflow module 10, the heating module 20 and the water outlet module 30 to work through the control module 40, so as to realize stable heating of the water entering the water system of the water supply device, effectively realize temperature feedback and real-time adjustment mechanism, and thus the purpose of more stably supplying water meeting the preset temperature can be realized. Meanwhile, the water inflow of the water supply device water system can also be controlled through the water inflow module 10, and the water can be refrigerated through the refrigeration module 50, so as to output the water meeting the preset temperature. The refrigeration module 50 can refrigerate the water and also store the water.

[0048] Please refer to Figure 2 as shown, Figure 2 The waterway structure diagram of the heating module 20 provided by the embodiment is shown in the figure, the heating module 20 comprises a heating unit and a heating energy storage unit 21, the heating unit is connected with the heating energy storage unit 21, and the heating energy storage unit 21 is connected with the water inflow module 10 and the water outlet module 30.

[0049] The heating unit is used for heating the water entering the heating energy storage unit.

[0050] The heating energy storage unit 21 is used for storing the water entering the heating energy storage unit.

[0051] Specifically, the heating unit comprises a heating subunit 23 and an instant heating unit 22, the heating subunit 23 is connected with the heating energy storage unit 21, and the instant heating unit 22 is connected with the heating energy storage unit and the water outlet module.

[0052] The heating subunit 23 is used for heating the water entering the heating energy storage unit 21.

[0053] The instant heating unit 22 is used for transmitting and / or heating the water output by the heating energy storage unit 21.

[0054] In a possible implementation, the heating energy storage unit 21 is connected with the water supplement port of the refrigeration module 50, so as to realize the sharing of the water supplement waterway of the refrigeration module 50 and the water supplement waterway of the heating energy storage unit 21 (that is, the waterway from the water inlet 11, the flow control valve 131, the on-off valve 132 to the water supplement port of the refrigeration module 50). Figure 5

[0055] ​In a possible implementation, the heating and energy storage unit 21 is connected to a water supplement port of the refrigeration module through a first one-way valve 51. The first one-way valve 51 is a one-way valve.

[0056] In a possible implementation, a first water pump 24 is arranged between the heating and energy storage unit 21 and the instant heating unit 22, and the first water pump 24 is configured to transmit water in the heating and energy storage unit 21 to the instant heating unit 22. The first water pump 24 is a water pump.

[0057] In a possible implementation, the heating module further includes an exhaust unit connected to the heating and energy storage unit 21, and the exhaust unit is configured to perform exhaust treatment on the heating and energy storage unit 21.

[0058] The heating and energy storage unit 21 can be a heat tank, which is a tank with heating and heat storage functions. The heat tank can heat water and store a certain amount of hot water, so as to meet the demand of a user for water at a preset temperature within a certain time, and play a role of buffering and continuously supplying water at the preset temperature. The instant heating unit 22 can be used to quickly heat water. By combining the instant heating unit 22 with the heat storage function of the heating and energy storage unit 21, water at the preset temperature can be quickly provided when needed, and the efficiency of supply is improved. It should be noted that the medium of the heating subunit 23 can be water or oil, which is not limited in the present application.

[0059] The instant heating unit 22 can quickly convert electric energy into heat energy through electric heating. In idle time, it can transfer heat to the heating and energy storage unit 21, so that the water in the heating and energy storage unit 21 is heated and heat is stored. The instant heating unit 22 can adopt a thick film technology, or other technologies, which are not limited here.

[0060] Please refer to Figure 3 as shown, Figure 3 Another water path structure schematic diagram of the heating module 20 is provided in the embodiment of the present application. The heating module 20 further includes an exhaust unit 24 connected to the heating and energy storage unit 21, and the exhaust unit 24 is configured to perform exhaust treatment on the heating and energy storage unit 21.

[0061] It should be noted that the exhaust unit 24 can include an exhaust pipe, which can be a pipe with a large diameter, such as a 3 / 8 pipe. During the operation of the water path system, gas may be generated, and the 3 / 8 pipe can better exhaust the gas, so as to avoid the accumulation of the gas and cause adverse effects on the system, such as abnormal pressure.

[0062] Please refer to Figure 4 as shown, Figure 4The water route structure schematic diagram of the water inlet module 10 is provided for the embodiment of the utility model, the water inlet module 10 includes water inlet 11, flow meter unit 12 and flow control unit 13, water inlet 11 is connected with flow meter unit 12 and flow control unit 13, flow meter unit 12 is connected with heating module 20, flow control unit 13 is connected with water outlet module 30, wherein,

[0063] Flow meter unit 12 is used for measuring the water flow to heating module 20;

[0064] Flow control unit 13 is used for flow control and distribution of water to the water route system of the water supply device.

[0065] It needs to be explained that water inlet 11 is the entrance of water to the water route system of the water supply device, and is the starting point of the whole water route circulation, and the external water source can enter the water route system of the water supply device through water inlet 11. Flow meter unit 12 can be used to measure the water flow input to heating module 20. By measuring the water flow entering heating module 20, the system can better control the heating process. For example, the heating power is adjusted according to the flow size to ensure that the water can be heated sufficiently and efficiently; if the flow is large, the heating power may need to be increased; if the flow is small, the heating power can be appropriately reduced to avoid energy waste.

[0066] Flow control unit 13 can be used for flow control and distribution of water to the water route system of the water supply device to control the flow of water according to the requirements (such as the user's requirement for hot water output, the safety limit of the system, etc.). At the same time, flow control unit 13 can also distribute water to different branches, for example, part of the water is directly distributed to water outlet module 30 as output without heating, or when cold water and hot water need to be mixed to adjust the water temperature, the corresponding distribution operation is carried out, which is not limited in the application.

[0067] Specifically as shown in the figure, Figure 4 Flow control unit 13 includes flow control valve 131 and on-off valve 132, the first end of flow control valve 131 is connected with water inlet 11, the second end of flow control valve 131 is connected with the first end of on-off valve 132, and the second end of on-off valve 132 is connected with water outlet module 30 and refrigeration module 50.

[0068] It needs to be explained that the application is explained by taking the combination of flow control valve 131 and on-off valve 132 as an example, which does not limit the application. When the system is in standby state or some conditions without water flow, on-off valve 132 is closed to prevent unnecessary water flow in the pipeline, thereby reducing heat loss and water resource waste. When water is needed, on-off valve 132 is opened, and flow control valve 131 can accurately control the flow to avoid too fast water consumption due to too large flow, thereby achieving the purpose of energy saving.

[0069] The on-off valve 132 and the flow control valve 131 can also prevent water hammer to some extent. Water hammer is a pressure wave caused by sudden changes in water flow, such as sudden closing of a valve, which can cause damage to pipes and equipment. When it is necessary to quickly stop the water flow, the flow control valve 131 is closed first to gradually reduce the flow, and then the on-off valve 132 is closed, which can effectively reduce the water hammer, prolong the service life of the equipment and pipes, and improve the safety of the system.

[0070] Optionally, only the flow control valve 131 can be used in the above embodiments to precisely adjust the size of the water flow, so as to avoid wasting water resources or problems such as too rapid water temperature drop due to excessive flow. Optionally, only the on-off valve 132 can be used in the above embodiments to control the on and off of the water path, so as to simply and quickly control the water path, which is not limited in the present application.

[0071] As shown in Figure 4 The flow meter unit 12 includes a first bidirectional valve 121 and a flow meter 122. The first end of the first bidirectional valve 121 is connected to the water inlet 11, and the second end of the first bidirectional valve 121 is connected to the flow meter 122.

[0072] It should be noted that the bidirectional valve (such as the first bidirectional valve 121 mentioned above and the second bidirectional valve mentioned below) can control the on and off of the water flow in two directions to provide a more flexible water flow control mode. In some complex water path circulation or water flow direction changing situations, the bidirectional valve can play an important role.

[0073] The flow meter 122 can measure the water flow entering the system, which helps the system to determine the initial water inlet condition, such as when the water inlet flow does not meet the expectation, which can prompt the system that there may be a water inlet pipe blockage, insufficient water pressure or other problems. Through the measurement of the flow meter 122, the system can perform preliminary troubleshooting at the start-up stage to ensure normal operation in the follow-up.

[0074] Optionally, the data provided by the flow meter 122 can help the system make water flow distribution decisions. Further, the data of the flow meter 122 can work with other components (such as the flow control valve 131, the NTC thermistor, etc.). For example, when the flow meter 122 detects a large water inlet flow and the NTC thermistor detects a slightly low water temperature, the system can appropriately increase the water flow into the heating module 20 by controlling the flow control valve 131, while adjusting the heating power to quickly raise the water temperature, thereby achieving precise supply.

[0075] Please refer to Figure 5 As shown in Figure 5A water route structure schematic diagram of a refrigeration module 50 is provided for the embodiments of the present application. Figure 5 As shown, the refrigeration module 50 includes a refrigeration unit 52 and a cold water pump 53, the water inlet of the refrigeration unit 52 is in communication with the second end of the on-off valve, and the water outlet of the refrigeration unit 52 is in communication with the water outlet module through the cold water pump.

[0076] The refrigeration unit 52 is used for refrigeration treatment of water entering the refrigeration module 50.

[0077] The cold water pump 53 is used for outputting the refrigerated water or the water entering the refrigeration module 50 to the water outlet module.

[0078] It should be noted that the refrigeration unit 52 can perform refrigeration treatment on the water entering the refrigeration module 50. For example, when the user needs cold water, the water flows into the refrigeration unit 52 from the second end of the on-off valve 132, and the refrigeration unit 52 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.

[0079] The cold water pump 53 in the refrigeration module 50 can play a role in power transmission, and can output the refrigerated water to the water outlet module 30. Optionally, in the case where the water does not need to be refrigerated, the cold water pump 53 can also directly deliver the water entering the refrigeration module 50 to the water outlet module 30. For example, when the device is in energy-saving mode or the user only needs normal temperature water, the cold water pump 53 can simply transmit the water without refrigeration treatment. Ensure the normal circulation and supply of water in the entire device water route system, so that the device can flexibly cope with different user demands for water temperature.

[0080] In one possible implementation, the refrigeration module 50 further includes a one-way valve 44 (such as a third one-way valve 54), the first end of the third one-way valve 54 is in communication with the cold water pump 53, and the second end of the third one-way valve 54 is in communication with the water outlet module 30.

[0081] Among them, the third one-way valve 54 can ensure that the water flows from the cold water pump 53 to the water outlet module 30, but prevents the water from flowing back from the water outlet module 30 to the cold water pump 53. The third one-way valve 54 can prevent backflow of water to protect the cold water pump 53 and the refrigeration unit 52 in the refrigeration module 50. The backflow of water can generate a reverse pressure on the cold water pump 53, causing the impeller of the cold water pump 53 to reverse, which can damage the motor and mechanical parts of the cold water pump 53. The third one-way valve 54 also helps to stabilize the water pressure and flow of the water outlet module 30, by limiting the reverse flow of water, it can ensure that the water received by the water outlet module 30 is supplied in the normal water flow direction and pressure designed by the device.

[0082] The bridging water path between the refrigeration module 50 and the heating and heat storage unit 22 of the heating module 20 includes a one-way valve 51 (referred to as a first one-way valve 51). Specifically, the heating and energy storage unit 21 is connected to the water supplement port of the refrigeration module 50 through the first one-way valve 51. The first one-way valve 51 is used to control the refrigeration module 50 or the water inlet module 10 to supplement water to the heating and heat storage unit 22.

[0083] The first one-way valve 51 can prevent hot water from flowing back into the refrigeration unit 52 from the exhaust unit 24 of the heating module 20. During operation of the device, the heating module 20 may

[0084] It can be understood that when the water in the refrigeration module 50 is sufficient, such as exceeding the maximum water level of the refrigeration module 50, the refrigeration module 50 can supplement water to the heating and heat storage unit 22 of the heating module 20 through the first one-way valve 51. Alternatively, when the water in the refrigeration module 50 is sufficient, the water in the water inlet module 10 cannot flow into the refrigeration module 50. At this time, the water inlet module 10 can supplement water to the heating and heat storage unit 22 of the heating module 20 through the first one-way valve 51, which is not limited in the present application.

[0085] Supplementing water to the heating and heat storage unit 22 through the bridging water path can maintain the normal operation of the heating and heat storage unit 22. During use, as the water in the heating and heat storage unit 22 continuously decreases, the water level will gradually decrease. By supplementing water from the refrigeration module 50 or the water inlet module 10, the water level of the heating and heat storage unit 22 can be maintained at an appropriate level to ensure that there is enough water for heating and storage, thereby ensuring that hot water can be continuously provided to the user.

[0086] In one possible implementation, the refrigeration module 50 further includes a two-way valve 55 (referred to as a second two-way valve 55). The first end of the second two-way valve 55 is connected to the refrigeration unit 52, and the second end of the second two-way valve 55 is connected to the on-off valve 132 of the water inlet module 10.

[0087] When it is detected that the water level in the refrigeration unit 52 is low or needs to be supplemented with new water, the second two-way valve 55 can open the path from the on-off valve 132 to the refrigeration unit 52, so that water can be smoothly supplemented into the refrigeration unit 52 to ensure that the refrigeration unit 52 always has enough water to cool and maintain the normal cooling function of the device.

[0088] When the sterilization program is started, the second two-way valve 55 can introduce water containing a sterilization component (such as water treated by ultraviolet disinfection, water added with a disinfectant, etc.) from the on-off valve 132 of the water inlet module 10 to the refrigeration unit 52, which is not limited in the application.

[0089] Please refer to Figure 6 , Figure 6 Another water path structure schematic diagram of the water supply device 1 is provided in the embodiment of the utility model. The water supply device 1 further comprises a drainage module 60, the drainage module 60 is communicated with the water outlet module 30, the heating module 20 and the refrigeration module 50;

[0090] The drainage module 60 comprises a first control valve, a waste water pump 62 and a drainage component 63, wherein the drainage component 63 is communicated with the waste water pump 62 and the first control valve;

[0091] The first control valve is used for controlling the waste water flowing from the water outlet module 30 to the drainage component 63;

[0092] The waste water pump 62 is used for transmitting the waste water of the heating module 20 and the waste water of the refrigeration module 50 to the drainage component 63;

[0093] The drainage component 63 is used for draining the waste water of the heating module 20, the waste water of the refrigeration module 50 and the waste water of the water outlet module 30.

[0094] Wherein, the drainage component 63 can be a component for draining water (such as waste water, etc.). The drainage component 63 can be a drainage pipeline, a drainage valve or a drainage port, or a specific drainage container, which is not limited in the application. The above components cooperate to ensure the effective treatment of waste water in the water supply device water path system.

[0095] In a possible implementation manner, as Figure 5 shown, the first control valve can be a three-way valve 61 (such as a second three-way valve 61), the first water path interface of the second three-way valve 61 is communicated with the water outlet module 30 through a water path, the second water path interface of the second three-way valve 61 is communicated with the heating module 10 and the refrigeration module 50 through a water path, and the third water path interface of the second three-way valve 61 is communicated with the waste water pump 62 through a water path.

[0096] The second three-way valve 61 can distribute water flow to three different directions, and can switch between different water path branches or mix water flow, etc. The second three-way valve 61 can not only regulate the water flow path, but also work in cooperation 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 waste water pump 62 connected thereto, so as to prepare for subsequent backflow of the water for re-heating.

[0097] It should be noted that the waste water pump 62 can be used to provide power for the water path backflow, so as to backflow and re-heat the water that does not meet the preset water temperature. When the water temperature does not meet the requirement, the waste water pump 62 can generate power through its own operation to drive the substandard water to flow in the reverse direction according to the predetermined water path. For example, the water that is originally to be discharged from the water outlet module 30 but whose temperature is not enough is transferred to the heating module 20 in the reverse direction through the switching of the second three-way valve 61, so that the water can be re-heated in the heating module 20 again to ensure that the finally output water temperature meets the standard, so as to ensure that the user can use water at a suitable temperature.

[0098] The backflow power provided by the waste water pump 62 can make the water temperature control of the entire water supply device system more accurate and stable, and avoid that the water whose temperature does not meet the standard is directly discharged and used by the user; and since only the substandard water needs to be re-heated, rather than all the water, the energy utilization efficiency of the entire system is also improved.

[0099] Please refer to Figure 6 shown, Figure 6 The water path structure of the water outlet module 30 provided by the embodiment of the utility model is shown in the figure, which comprises a bidirectional valve 31 (referred to as a first bidirectional valve 31), a negative temperature coefficient (Negative Temperature Coefficient, NTC) thermistor 32, a check valve 33 (referred to as a second check valve 33) and a water outlet 34. The first end of the first bidirectional valve 31 is in communication with the instant heating unit 22 and the water inlet module 10, and the second end of the first bidirectional valve 31 is in communication with the water drainage module 60 and the first end of the NTC thermistor 32. The first end of the NTC thermistor 32 is in communication with the refrigeration module 50. The second end of the NTC thermistor 32 is in communication with the first end of the second check valve 33, and the second end of the second check valve 33 is in communication with the water outlet 34, wherein,

[0100] The NTC thermistor 32 is used for measuring the temperature of the conveyed water.

[0101] The water outlet 34 is used for outputting water meeting the preset temperature.

[0102] It should be noted that the water outlet module 30 can perform accurate water temperature detection to further perform water temperature screening and water route shunting. Through the above strict temperature screening mechanism, the entire water supply device system can always provide stable water meeting the temperature requirements for the user, which not only can improve the user satisfaction, but also can improve the practicability of the entire system.

[0103] Optionally, the shunting function of the water outlet module 30 also helps 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 re-heating the water with unqualified water temperature, or checking whether the instant heating unit 22 and the heating energy storage unit 21 are faulty, etc., so as to ensure the continuous and stable operation of the entire system.

[0104] Optionally, the exhaust unit 24 is connected with the water outlet 34 to discharge the gas generated in the water route system during operation through the water outlet 34, so as to avoid the adverse effects of gas accumulation on the system.

[0105] The exhaust unit 24 is also used to supplement air for the waste water pump in the drainage module 60 when the waste water in the water outlet module 30, the waste water in the refrigeration module 50, and the waste water in the heating energy storage unit 21 are drained through the air hole or the drainage component of the water outlet module 30. The drainage component can be a faucet at the drainage port and the like.

[0106] It can be understood that the first bidirectional valve 31 can be used to transport water from the instant heating unit 22 to the NTC thermistor 32. Optionally, the first bidirectional valve 31 can also be used to transport 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 transport the water meeting the preset water temperature to the water outlet, and transport the water not meeting the preset water temperature to the drainage module 60 through the first bidirectional valve 31.

[0107] In a possible implementation, the second one-way valve 33 is used to control the first type of liquid to be discharged from the water outlet module, and to prevent the second type of liquid from entering from the outside.

[0108] The first type of liquid can be the liquid required in the water route system of the water supply device, such as sterilization water when sterilization treatment is required, and high-temperature water when high-temperature flushing is required. The second type of liquid can be the liquid that is not required by the water supply device from the outside, such as coffee, milk, etc., which are not limited in the present application.

[0109] The second one-way valve 33 can be used to control the water flow direction to ensure that the water can only flow in a specific direction. By evaluating its pressure, it can be determined whether it can work normally under different pressure conditions, thereby preventing problems such as backflow, and ensuring the normal operation of the waterway system. The second one-way valve 33 in the embodiment of the application can prevent the sterilization water from being discharged from the faucet, and prevent external liquids (such as coffee, etc.) from being sucked back into the waterway, thereby keeping the waterway system clean and preventing pollution, etc., which is not limited by the application.

[0110] When the water obtained after heating flows to the water outlet 34, the NTC thermistor 32 installed in the internal waterway can 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 as the temperature increases, and the resistance value increases as 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 which time the control module 40 keeps the waste water waterway of the drainage module 60 closed to supply the user with water meeting the temperature requirements.

[0111] Through the above-mentioned accurate temperature control mechanism, it can be ensured that the output water always meets the temperature requirements, and the influence caused by the water temperature being cold and hot alternately can be avoided, and the water that does not meet the temperature can be avoided to be wastedly discharged. Returning the water that does not meet the temperature to be reheated instead of reheating all the water can help to save energy and improve the energy utilization efficiency of the water supply device.

[0112] Those skilled in the art can clearly understand that, for the convenience and brevity of description, only the above-mentioned division of each functional unit and module is exemplified, and in actual application, the above-mentioned functions can be completed by different functional units and modules according to needs, that is, the internal structure of the device is divided into different functional units or modules to complete all or part of the functions described above.
