[0043] 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 some 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 the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0044] Please refer to Figure 1 as shown, Figure 1 Fig. 1 is a schematic diagram of a water path structure of a water supply device 1 provided in an embodiment of the present application. The water supply device 1 comprises a water inlet module 10, a heat exchange module 21, a heating and energy storage module 22, a water outlet module 30 and a control module 40.
[0045] The water inlet module 10 is in communication with the heat exchange module 21, the heating and energy storage module 22 and the water outlet module 30, and is used to control the water inlet amount of water entering the water supply device 1.
[0046] The heat exchange module 21 is in communication with the heating and energy storage module 22, the water inlet module 10 and the water outlet module 30, and is used to exchange heat with and / or transmit water entering the heat exchange module 21 from the water inlet module 10.
[0047] The heating and energy storage module 22 is used to heat and store water entering the heating and energy storage module 22 and / or store water entering the heating and energy storage module 22.
[0048] The water outlet module 30 is used to output water meeting a preset water temperature.
[0049] The control module 40 is electrically connected with the water inlet module 10, the heat exchange module 21, the heating and energy storage module 22 and the water outlet module 30, and is used to control the water inlet module 10, the heat exchange module 21, the heating and energy storage module 22 and the water outlet module 30 to work.
[0050] It should be noted that the hot water and the flow adding water path have relatively low requirements on flow rate. In order to save space and material cost while meeting the functions, the hot water and the flow adding 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 and cold water path can be relatively large. The normal temperature and 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.
[0051] The heat exchange module 21 can be a device that transfers heat from one fluid to another fluid through 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 single heat host waterway scheme 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. Optionally, the heat exchange module 21 and the heating energy storage module 22 can be used as a heater in the water supply device 1, and the present application does not limit this.
[0052] It can be understood that, compared with direct heating methods (such as electric heating, flame heating, etc.), the heat exchange module has higher energy utilization rate. For example, the heat exchange module can use industrial waste heat, waste heat, etc. for heating, thereby greatly improving the utilization rate of energy and reducing energy waste. The heat exchange module has accurate temperature control. The heat exchange module can achieve accurate temperature control by adjusting the flow rate, temperature, etc. of the fluid. The heat exchange module has high safety. Compared with flame heating and other methods, the heat exchange module has no open flame and has an advantage in safety.
[0053] The embodiment first controls the water inflow of the waterway system of the water supply device through the water inflow module 10, heats the water entering the waterway system of the water supply device through the heat exchange module 21, stores the heated hot water, detects the water temperature through the water outlet module 30, and outputs water meeting the preset water temperature. Through effective temperature feedback and real-time adjustment mechanism, stable and efficient heating can be achieved, so that the purpose of more stably and efficiently supplying water meeting the preset temperature can be achieved.
[0054] Please refer to Figure 2 , Figure 2 Another waterway structure schematic diagram of the water supply device 1 provided in the embodiment is shown in the figure. The water supply device 1 further comprises a circulating water pump 23. The circulating water pump 23 is in communication with the heating energy storage module 22 and the heat exchange module 21. The circulating water pump 23 is used to pump the water stored in the heating energy storage module 22 into the heat exchange module 21.
[0055] The circulating water pump 23 is used to pump the water stored in the heating energy storage module 22 into the heat exchange module 21.
[0056] It should be noted that the medium of the heating energy storage module 21 can be water or oil, and the present application does not limit this. The heating energy storage module 21 can be a heat tank. The heat tank is a tank with heating and heat storage functions. It can heat water and store a certain amount of hot water to meet the demand of users for hot water within a certain period of time, and play a role in buffering and continuously supplying hot water.
[0057] In a possible implementation, please refer to Figure 3 , Figure 3A water path structure schematic diagram of the heating energy storage module 22 is provided for the embodiment of the utility model. Wherein, the heating energy storage module 22 comprises a heating unit 221, and the heating unit 221 is used for heating treatment to the water entering the heating energy storage module 22;The heating energy storage module 22 comprises a heat storage unit 222, and the heat storage unit 222 is used for storing the hot water obtained after heating treatment.
[0058] In a possible implementation, please refer to Figure 4 As shown in the figure, Figure 4 A water path structure schematic diagram of the water supply device 1 is provided for another embodiment of the utility model. Wherein, the water supply device 1 further comprises an exhaust unit 24, and the exhaust unit 24 is communicated with the heating energy storage module 22 and the water outlet module 30, wherein,
[0059] The exhaust unit 24 is used for exhaust treatment to the heating energy storage module 22 through the air hole of the water outlet module 30.
[0060] It should be noted that the exhaust unit 24 can comprise an exhaust pipe, and the exhaust pipe can adopt a pipe with a larger 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, avoiding the adverse effects of gas accumulation on the system, such as pressure abnormalities.
[0061] Please refer to Figure 5 As shown in the figure, Figure 5 A water path structure schematic diagram of the water inlet module 10 is provided for the embodiment of the utility model, and the water inlet module 10 comprises a water inlet 11, a flow detection unit 12 and a flow control unit 13, the water inlet 11 is communicated with the flow detection unit 12 and the flow control unit 13, the flow detection unit 12 is communicated with the heat exchange module 21, and the flow control unit 13 is communicated with the water outlet module 30 and the heating energy storage module 22, wherein,
[0062] The flow detection unit 12 is used for detecting the water flow to the heat exchange module 21;
[0063] The flow control unit 13 is used for controlling the water flow entering the water outlet module 10 and the heating energy storage module 22.
[0064] It should be noted that the water inlet 11 is the inlet of the water into the water path system of the water supply device, and is the starting point of the whole water path circulation, and the external water source can enter the water path system of the water supply device through the water inlet 11. The flow detection unit 12 can be used for measuring the water flow input to the heat exchange module 21. By measuring the water flow entering the heat exchange module 21, the system can better control the heating process. For example, the heating power is adjusted according to the flow size, so as 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.
[0065] The flow control unit 13 can control the flow of water entering the water outlet module 10 and the heating energy storage module 22 to better control the flow of water according to the demand (such as the user's requirement 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, part of the water is directly distributed to the water outlet module as output without heating, or the corresponding distribution operation is performed when cold water and hot water need to be mixed to adjust the water temperature, which is not limited in the present application.
[0066] In a possible implementation, as shown in Figure 5 The flow control unit 13 is connected to the heating energy storage module 22, and the flow control unit 13 is further configured to supplement water to the heating energy storage module 22 when the water amount of the heating energy storage module 22 is lower than the preset water amount. Specifically, a water supplement control valve 25 is arranged between the flow control unit 13 and the heating energy storage module 22, and the water supplement control valve 25 is configured to control the water supplement to the heating energy storage module.
[0067] It can be understood that the flow control unit 13 is connected to the heating energy storage module 22 and supplements water when the water amount of the heating energy storage module 22 is lower than the preset water amount, which can maintain sufficient water amount in the heating energy storage module 22, ensure that the heating energy storage module 22 is always in a normal working state, avoid the risk of dry burning of the heating element due to insufficient water amount, and ensure the safe and stable operation of the equipment. When the water amount of the heating energy storage module 22 is insufficient, timely water supplement helps to maintain the continuous supply of water meeting the preset temperature, and through timely water supplement, even in the case of large demand, water meeting the preset temperature can be continuously output from the heating energy storage module 22 to meet the uninterrupted demand of the user, thereby improving the user experience.
[0068] Please refer to Figure 6 as shown, Figure 6 Another water path structure schematic diagram of the water inlet module 10 provided by the embodiment of the present application is shown. In a possible implementation, the flow detection unit 12 includes a bidirectional valve 121 (such as a first bidirectional valve) and a flow meter 122, the first end of the first bidirectional valve 121 is connected to the water inlet 11, the second end of the first bidirectional valve 121 is connected to the flow meter 122, and the flow meter 122 is connected to the heat exchange module 21.
[0069] 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, 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 and the heating energy storage module 22.
[0070] 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-off of water flow in two directions to provide more flexible water flow control. In some complex water circulation or water flow direction changing cases, the bidirectional valve can play an important role.
[0071] The flow meter 122 can measure the water flow entering the system, which helps the system to determine the initial water inflow condition. For example, if the water inflow does not meet the expected value, the system can prompt that there may be a water inflow pipe blockage, insufficient water pressure or other problems. Through the measurement of the flow meter, the system can perform preliminary troubleshooting at the start-up stage to ensure normal operation in the follow-up stage.
[0072] 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 and the Negative Temperature Coefficient (NTC) thermistor mentioned below). For example, when the flow meter 122 detects a large water inflow and the NTC thermistor detects a slightly low water temperature, the system can appropriately increase the water inflow by controlling the flow control valve 131, while adjusting the heating power to quickly raise the water temperature, thereby achieving accurate supply.
[0073] It should be noted that the application is described by using the combination of the flow control valve 131 and the on-off valve 132 as an example, which does not limit the application. When the system is in standby state or some cases where water flow is not needed, the on-off valve 132 is closed to prevent unnecessary water flow in the pipeline, thereby reducing heat loss and water waste. When water is needed, the on-off valve 132 is opened, and the flow control valve 131 can accurately control the flow to avoid excessive water consumption due to excessive flow, thereby achieving the purpose of energy saving.
[0074] The use of 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 the valve), which can cause damage to the pipeline 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 phenomenon, prolong the service life of the equipment and pipeline, and improve the safety of the system.
[0075] Optionally, only the flow control valve 131 can be used in the above embodiments to precisely adjust the flow size of the water flow, so as to avoid waste of water resources or problems such as too fast water temperature drop due to too large 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 realize the control of the water path, which is not limited in the application.
[0076] Please refer to Figure 7 as shown, Figure 7 Another water path structure schematic diagram of the water supply device 1 is provided for the embodiments of the utility model. The water supply device 1 further comprises a drainage module 50, which is communicated with the water outlet module 10, the heating energy storage module 22, the heat exchange module 21 and the control module 40, wherein,
[0077] The drainage module 50 is used to assist the backflow of the water path and discharge waste water of the heating energy storage module 22, the heat exchange module 21 and the water outlet module 30.
[0078] The heating energy storage module 22 is further used to store the water backflowed by the drainage module 50.
[0079] In a possible implementation, the heating energy storage module 22 is further used to secondarily heat and store the water backflowed by the drainage module 50.
[0080] Since the backflowed water may have a certain initial temperature, compared with directly heating the cold water, the energy consumption required for heating the backflowed water to the preset water temperature is reduced. For the heating energy storage module 22, secondarily heating and storing the backflowed water that does not reach the preset water temperature can fully utilize the existing heating mechanism and heat preservation performance of the heating energy storage module itself, reduce the overall energy input, improve the energy utilization rate and reduce the operation cost. When the demand for water at the preset temperature of the user appears peak and trough fluctuation, the heating energy storage module can flexibly adjust the output of the water according to the amount of hot water stored in the heating energy storage module and the backflow heating condition, so as to ensure stable supply of water meeting the preset temperature within a certain period of time. Even when the external supply source (such as the heating capacity of the main machine) appears temporary fluctuation, the reserved water in the heating energy storage module and the water being secondarily heated can maintain the continuous supply of water, reduce the possibility of supply interruption and improve the user experience.
[0081] Please refer to Figure 8 as shown, Figure 8 A water path structure schematic diagram of the drainage module 50 is provided for the embodiments of the utility model. The drainage module 50 comprises a control valve 501, a drainage power component 502 and a drainage component 503, wherein the drainage component 503 is communicated with the drainage power component 502 and the control valve 501.
[0082] A control valve 501 is used to control the flow of wastewater from the water outlet module 30 to the drainage component 503.
[0083] A drainage power component 502 is used to transport the wastewater of the heat exchange module 21 and / or the heating energy storage module 22 to the drainage component 503.
[0084] A drainage component 503 is used to drain the wastewater.
[0085] The drainage power component 502 can be a component that provides power for the process of draining the wastewater or the process of backflow of the waterway. The drainage power component 502 can be a wastewater pump or a compressible air bag, and the present application does not make any limitation. The drainage component 503 can be a component for draining water (such as wastewater, etc.). The drainage component 503 can be a drainage pipeline, a drainage valve or a drainage port, or a specific drainage container, and the present application does not make any limitation. The above-mentioned components cooperate to ensure the effective treatment of the wastewater in the waterway system of the water supply device.
[0086] In a possible implementation, please refer to Figure 9 as shown, Figure 9 a schematic diagram for supplementing air through the air hole 301 of the water outlet module 30 is provided. The gas releasing unit 23 is further used to supplement air to the drainage power component 502 in the drainage module 50 when draining the wastewater in the water outlet module 30 through the air hole 301 of the water outlet module 30.
[0087] The air hole 301 of the water outlet module 30 can supplement air to the drainage power component. Specifically, a one-way valve can be installed at the air hole 301 to pump the water in the pipeline. The mode of the air hole 301 and the one-way valve can be realized by a compressible water bag.
[0088] In a possible implementation, please refer to Figure 10 as shown, Figure 10 a schematic diagram for supplementing air through the water outlet component 302 of the water outlet module 30 is provided. The gas releasing unit 23 is further used to supplement air to the drainage power component 502 in the drainage module 50 when draining the wastewater in the water outlet module 30 through the water outlet component 302 of the water outlet module 30.
[0089] The water outlet component 302 can be a component that provides water (to a user). The water outlet component 302 can be a faucet, a shower head, a spray head, or a water outlet nozzle, etc. Taking the water outlet component 302 as a faucet as an example, air can be introduced through the air outlet of the faucet to supplement air to the drain power component, which is not limited in the present application. When the drain power component 502 drains the wastewater in the water outlet module 30, the drain process will cause the pressure in the pipeline to change. Air supplementation can prevent negative pressure from occurring during the drain process. Through air supplementation, the pressure in the pipeline can be kept relatively stable, ensuring that the drain power component 502 can work continuously and stably, and helping to improve the drain efficiency of the drain power component 502.
[0090] Referring to Figure 11 as shown, Figure 11 A water path structure schematic diagram of a water outlet module 30 is provided in the embodiments of the present application. The water outlet module 30 comprises a second bidirectional valve 311 (also referred to as a second bidirectional valve), a negative temperature coefficient (NTC) thermistor 312, a one-way valve 313, and a water outlet component 314. The first end of the second bidirectional valve 311 is in communication with the heat exchange module 21 and the on-off valve 132 of the water inlet module 10. The second end of the second bidirectional valve 311 is in communication with the drain module 50 and the first end of the NTC thermistor 312. The second end of the NTC thermistor 312 is in communication with the first end of the one-way valve 313. The second end of the one-way valve 313 is in communication with the water outlet component 314. Among them,
[0091] The NTC thermistor 312 is used to measure the temperature of the delivered water.
[0092] The water outlet component 314 is used to output water that meets the preset temperature.
[0093] It should be noted that the water outlet module 30 can perform accurate water temperature detection to further perform water temperature screening and water path diversion. Through the above strict temperature screening mechanism, the entire water supply device system can always provide stable water that meets the temperature requirements for the user, which not only can improve the user satisfaction, but also can improve the practicability of the entire system.
[0094] Optionally, the diversion function of the water outlet module 30 also helps the stable operation of the system. After the water with unqualified temperature is drained to the drain module 50, the system can take appropriate measures according to the specific circumstances, such as re-heating the water with unqualified temperature or checking whether the heat exchange module 21 and the heating energy storage module 22 are faulty, etc., so as to ensure the continuous and stable operation of the entire system.
[0095] Optionally, the air exhaust unit 24 is in communication with the water outlet component 314 to exhaust the gas generated during the operation of the water path system through the water outlet component 314, thereby avoiding the adverse effects of gas accumulation on the system.
[0096] It can be understood that the second bidirectional valve 311 can be used to transport water from the heat exchange module 21 to the NTC thermistor 312; alternatively, the second bidirectional valve 311 can also be used to transport water from the on-off valve 132 to the drainage module 50. Alternatively, the NTC thermistor can be used for water temperature detection, and water meeting the preset water temperature is transported to the water outlet component 314, and water not meeting the preset water temperature is transported to the drainage module through the bidirectional valve.
[0097] In a possible implementation, the water outlet module 30 includes a one-way valve 313, which is in communication with the water outlet component 314 and the second bidirectional valve 311; wherein the one-way valve 313 is used to control the first type of liquid to be discharged from the water outlet module 30, and to prevent the second type of liquid from entering the water outlet module from the outside.
[0098] The first type of liquid can be a liquid required in the water supply device waterway system, such as sterilization water when sterilization is required, or high-temperature water when high-temperature flushing is required. The second type of liquid can be a liquid that is not required by the external water supply device, such as coffee, milk, and the like, which are not limited in the present application.
[0099] The one-way valve 314 can be used to control the direction of water flow to ensure that water can only flow in a specific direction. It can be determined whether it can work normally under different pressure conditions by evaluating its pressure, so as to prevent problems such as backflow, thereby ensuring the normal operation of the waterway system. The one-way valve 314 in the embodiment of the present application can prevent 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, which is not limited in the present application.
[0100] When the water obtained after heating flows to the water outlet component 314, the NTC thermistor 312 installed in the internal waterway can monitor the water temperature in real time. The resistance value of the NTC thermistor 312 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 312 is in the normal range, at which time the control module 40 keeps the waste water channel of the drainage module 50 closed to supply the water meeting the requirements to the user.
[0101] Optionally, if the water temperature is lower than the set qualified temperature, the resistance value of the NTC thermistor 312 changes, which is detected by the control module 40. At this time, the control module 40 can determine that the water temperature is not up to standard according to the detected temperature, and turn on the waste water channel of the drainage module 50. Optionally, the substandard water can be returned through the waste water channel, and can be usually returned to the heat exchange module 21 and / or the heating energy storage module 22 through the drainage module 50 for re-heating until the temperature reaches the qualified standard again, so as to be further output for use by the user.
[0102] Through the above-mentioned accurate temperature control mechanism, it can be ensured that the output water always meets the temperature requirement, and the influence caused by the water temperature being cold and hot alternately can be avoided, and the substandard water can be avoided from being wastedly discharged. Returning the substandard water for re-heating instead of re-heating all the water can help save energy and improve the energy utilization efficiency of the water supply device.
[0103] Please refer to Figure 12 As shown in the figure, Figure 12 A water channel structure diagram of the drainage module 50 provided by the embodiment of the utility model is shown. The drainage module 50 includes a three-way valve 41, a drainage power component 42 and a waste water drainage port 43, the first end of the three-way valve 41 is communicated with the second two-way valve 311 of the water outlet module 30, the second end of the three-way valve 41 is communicated with the heat exchange module 21 and the heating energy storage module 22, the third end of the three-way valve 41 is communicated with the drainage power component 42, the drainage power component 42 is communicated with the waste water drainage port 43, wherein,
[0104] The drainage power component 42 is used for transmitting water to the waste water drainage port;
[0105] The waste water drainage port 43 is used for discharging the water transmitted by the drainage power component.
[0106] It should be noted that the three-way valve 41 can distribute water flow to three different directions, and the three-way valve 41 can switch between different water channel branches or mix water flow, etc. The three-way valve 41 can not only regulate the water flow path, but also work cooperatively with other modules. For example, when the water temperature detection unit finds that the water temperature does not meet the preset water temperature, the three-way valve 41 can change the water flow path to guide the substandard water to one end of the drainage power component 42 connected thereto, so as to prepare for the subsequent return of the water for re-heating.
[0107] The drain power component 42 can be used to provide power to make the water return to the waterway, so as to return and reheat the water that does not meet the preset water temperature. When the water temperature does not meet the requirement, the drain power component 42 can generate power by its own operation to drive the substandard water to flow in the reverse direction of the predetermined waterway. For example, the water that is originally to be discharged from the water outlet module 30 but whose temperature is not enough is diverted by the three-way valve 41 to be transported in the direction of the heat exchanger 21 and the heating energy storage module 22 in the reverse direction, so that the water can be re-heated in the heat exchanger 21 and the heating energy storage module 22 to ensure that the finally output water temperature meets the requirement, so as to ensure that the user can use the water of the appropriate temperature.
[0108] The return flow power provided by the drain power component 42 can make the water temperature control of the entire water supply device system more accurate and stable, and avoid that the water that does not meet the requirement is directly discharged and used by the user; and since only the part of the water that does not meet the requirement needs to be re-heated, instead of repeatedly heating all the water, the energy utilization efficiency of the entire system is also improved.
[0109] The waste water can include not only the excess water generated in the process of re-heating the water whose temperature does not meet the preset water temperature, but also some impurity water generated during the operation of the system, water discharged during maintenance, etc. The waste water is discharged from the system through the waste water drain 43, so as to keep the waterway system clean and prevent the impurities from accumulating to adversely affect the normal operation of the system and the water quality, thereby prolonging the service life of the system.
[0110] The water supply device provided in the application can effectively transfer the heat generated by the main machine to the water that needs to be heated through the heat exchange module, can efficiently transfer the heat, can accelerate the heat exchange by using a larger contact area and a reasonable structure, can improve the heating efficiency, can accurately control the water temperature, can avoid the water temperature fluctuation by adjusting the fluid flow and other parameters, can exhibit excellent performance in many fields, and has more competitiveness compared with the traditional way, and can effectively guarantee the stable operation of the system and the accurate energy supply requirement.
