Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] This invention proposes a water system 100 that can discharge low-temperature water from the water system 100 and raise the temperature of the first cup of water, thereby improving the user experience. It also proposes a tankless water dispenser 1000, which includes the aforementioned water system 100.

[0032] like Figure 1 According to the embodiment of the present utility model, the water system 100 includes an inlet component 10, a heating component 20, an outlet component 30, and a drainage component 40.

[0033] The water inlet assembly 10 includes a negative pressure valve 11 and a water pump 12. The inlet of the water pump 12 is connected to the negative pressure valve 11. The heating assembly 20 is connected to the outlet of the water pump 12. The water outlet assembly 30 is connected to the heating assembly 20 and is used to supply hot water. The drain assembly 40 is connected between the heating assembly 20 and the water outlet assembly 30 and is used to discharge wastewater. In this way, low-temperature water in the water system 100 can be discharged, and the temperature of the first cup of water can be increased.

[0034] For example, the water system 100 can be applied to a tankless water dispenser. It is understood that the water inlet assembly 10 includes a negative pressure valve 11 and a water pump 12. The water pump 12 can be connected to a water source and a heating assembly 20, and pumps the water from the water source to the heating assembly 20. The heating assembly 20 heats the water flowing through it and outputs hot water through the water outlet assembly 30. The negative pressure valve 11 can eliminate the pressure of the water flow at the front end. When the water pump 12 is driven, the pressure at the outlet end of the negative pressure valve 11 is lower than a preset value and it opens, so that the heating assembly 20 can stably regulate the temperature of the water flow, thereby eliminating the water tank in the water dispenser, reducing the size of the water dispenser, and reducing costs. However, after the last use, the water temperature in the water system 100 drops, and the first cup of water when the user gets hot water again is cold. Therefore, a drain component 40 can be connected between the heating component 20 and the water outlet component 30. When the user gets hot water, the drain component 40 can first drain the low-temperature water from the outlet of the heating component 20. When the water temperature at the outlet of the heating component 20 reaches the preset value, it is discharged through the water outlet component 30, thus meeting the user's need for hot water and improving the user experience.

[0035] Therefore, the water system 100 according to the present invention can discharge low-temperature water from the water system 100 and increase the temperature of the first cup of water, thereby improving the user experience.

[0036] It should be understood that the negative pressure valve 11 is a valve that controls the opening and closing of the water circuit. The outlet end of the negative pressure valve 11 can work in conjunction with the water pump 12. When the water pump 12 is working, the pressure at the outlet end of the negative pressure valve 11 is lower than the preset value and it opens. When the water pump 12 stops working, the pressure at the outlet end of the negative pressure valve 11 is not lower than the preset value and it closes.

[0037] like Figure 1 In some embodiments of this utility model, the water outlet component 30 includes a first control unit for controlling the on / off state of the water outlet component 30, and the drain component 40 includes a second control unit for controlling the on / off state of the drain component 40. It can be understood that when the user draws hot water again, the first control unit controls the water outlet component 30 to close and the second control unit controls the drain component 40 to open, discharging the low-temperature water from the outlet of the heating component 20. When the water temperature at the outlet of the heating component 20 reaches a preset value, the first control unit controls the water outlet component 30 to open and the second control unit controls the drain component 40 to close. At this time, the temperature of the first cup of water drawn by the user meets the requirements, thereby improving the user experience.

[0038] In some embodiments of this utility model, the first control unit and the second control unit are combined to form a reversing valve. Specifically, when the water dispenser is turned on again and the user gets hot water, the reversing valve can control the heating component 20 to be connected to the drain component 40 and control the heating component 20 to be disconnected from the water outlet component 30, so that the low-temperature water at the outlet end of the heating component 20 is discharged. When the outlet water temperature of the heating component 20 reaches a preset value, the reversing valve can control the heating component 20 to be disconnected from the drain component 40 and control the heating component 20 to be connected to the water outlet component 30, thereby meeting the user's need for hot water.

[0039] like Figure 1 In some other embodiments of this utility model, the first control unit and the second control unit are respectively switch valves; specifically, the first control unit is set as a first switch valve 32, and the second control unit is set as a second switch valve 42; when the water dispenser is turned on again and the user gets hot water, the first switch valve 32 can control the water outlet component 30 to close, and the second switch valve 42 can control the drain component 40 to open, so that the heating component 20 is isolated from the water outlet component 30, and the heating component 20 is connected to the drain component 40, so as to discharge the low-temperature water at the water outlet end of the heating component 20. When the water outlet temperature of the heating component 20 reaches the preset value, the first switch valve 32 can control the water outlet component 30 to open, and the second switch valve 42 can control the drain component 40 to close, so that the heating component 20 is connected to the water outlet component 30, and the heating component 20 is isolated from the drain component 40, so as to discharge the low-temperature water at the water outlet end of the heating component 20, thereby meeting the user's need for hot water and avoiding the residual low-temperature water in the water system 100 from affecting the user's experience.

[0040] In some embodiments of this utility model, the water system 100 further includes a controller. The controller has a timing unit and communicates with the water outlet component 30, the drainage component 40, and the heating component 20 respectively. The controller is configured to control the water outlet component 30 to disconnect and control the drainage component 40 to connect when the running time of the heating component 20 is less than a preset time, and to control the water outlet component 30 to connect and control the drainage component 40 to disconnect when the running time of the heating component 20 is greater than or equal to the preset time. In this way, the user's need for hot water can be met, and the user experience can be improved.

[0041] For example, when the user draws hot water again, the timing unit can calculate the running time of the heating component 20. If the running time of the heating component 20 has not reached 5 seconds, the controller controls the water outlet component 30 to close and the drain component 40 to open, thereby discharging the low-temperature water from the water outlet of the heating component 20. When the timing unit calculates that the running time of the heating component 20 has reached 5 seconds, the controller controls the water outlet component 30 to open and the drain component 40 to close, thereby releasing the hot water from the water outlet of the heating component 20, raising the temperature of the user's first cup of water, and meeting the user's usage needs.

[0042] In some embodiments of this utility model, the water system 100 further includes a temperature sensor for detecting the outlet water temperature of the heating component 20. The temperature sensor communicates with the outlet component 30 and the drain component 40 respectively. The water system 100 is configured to control the outlet component 30 to disconnect and control the drain component 40 to connect when the outlet water temperature is lower than a preset temperature value, and to control the outlet component 30 to connect and control the drain component 40 to disconnect when the outlet water temperature is greater than or equal to the preset temperature value. In this way, the user's need for hot water can be met, and the user experience can be improved.

[0043] For example, a temperature sensor is disposed between the heating component 20 and the water outlet component 30 to detect the water temperature at the outlet of the heating component 20. When the user draws hot water again, if the temperature sensor detects that the water temperature at the outlet of the heating component 20 has not reached 80°C, the temperature sensor communicates with the water outlet component 30 and the drain component 40 and controls the water outlet component 30 to close and the drain component 40 to open, thereby discharging the low-temperature water at the outlet of the heating component 20. When the temperature sensor detects that the water temperature at the outlet of the heating component 20 has reached 80°C, the temperature sensor controls the water outlet component 30 to open and the drain component 40 to close, thereby releasing the hot water at the outlet of the heating component 20, raising the temperature of the user's first cup of water, and meeting the user's usage needs.

[0044] like Figure 1In some embodiments of this utility model, the water system 100 further includes a flow detection element 83, which is connected to the inlet end of the negative pressure valve 11. It is understood that the flow detection element 83 can detect the water flow rate towards the negative pressure valve 11, and the flow detection element 83 can be communicatively connected to the heating component 20 to stabilize the water flow rate towards the heating component 20 within a preset range. Specifically, the water system 100 has a first preset flow rate and a second preset flow rate, where the second preset flow rate is greater than the first preset flow rate. When the heating component 20 heats the water, the water flow rate through the heating component 20 must be no less than the first preset flow rate and no greater than the second preset flow rate. When the water flow rate through the heating component 20 is less than the first preset flow rate, the heating component 20 is prone to dry burning due to the low water flow rate. At this time, when the flow detection element 83 detects that the water flow rate is less than the first preset flow rate, it controls the heating component 20 to stop operating to avoid damage to the heating component 20. If the water flow rate through the heating component 20 is greater than the second preset flow rate, the heating component 20 cannot heat the water well due to the high water flow rate. At this time, when the flow detection element 83 detects that the water flow rate is greater than the second preset flow rate, it can control the water pump 12 to adjust the inlet water flow rate to avoid the outlet water temperature failing to meet the user's needs.

[0045] like Figure 1 In some embodiments of this utility model, the water system 100 further includes a warm water component 50. The inlet of the warm water component 50 is connected to the water inlet of the negative pressure valve 11, and the outlet is connected to the water outlet component 30. In this way, the user's warm water needs can be met and the user's experience can be improved.

[0046] Specifically, the water system 100 may include a hot water circuit and a warm water circuit, which are connected in parallel. The hot water circuit includes an inlet component 10 and a heating component 20 connected in sequence, and the warm water circuit includes a warm water component 50. The inlet of the warm water component 50 is connected to the inlet end of the negative pressure valve 11, and the outlet of the warm water component 50 is connected to the outlet component 30. In actual use, when the user needs hot water, the water can flow from the water source and flow through the inlet component 10, the heating component 20 and the outlet component 30 in sequence to achieve hot water output. When the user needs warm water, the water can flow from the water source and flow through the warm water component 50 and the outlet component 30 in sequence to achieve warm water output.

[0047] like Figure 1 In some embodiments of this utility model, the warm water component 50 includes a warm water valve 51 and a sterilization module 52. The warm water valve 51 is connected to the sterilization module 52, the inlet end of the warm water valve 51 is connected to the inlet end of the negative pressure valve 11, and the outlet end of the sterilization module 52 is connected to the water outlet component 30. In this way, the user's warm water needs can be met and the user's experience can be improved.

[0048] When in use, if the user needs hot water, the water pump 12 can be started, and the outlet pressure of the negative pressure valve 11 is lower than the preset value and it opens, so that the water flows out from the water source and flows through the negative pressure valve 11, the water pump 12, the heating component 20 and the water outlet component 30 in sequence to achieve hot water output; if the user needs warm water, the water pump 12 can be stopped and started, the warm water valve 51 opens, and the water flows out from the water source and flows through the warm water valve 51, the sterilization module 52 and the water outlet component 30 in sequence to achieve warm water output. Among them, the sterilization module 52 can sterilize and disinfect the water flow to improve the cleanliness of drinking water.

[0049] In some examples, the sterilization module 52 can use ultraviolet radiation to sterilize and disinfect the water flowing through the sterilization module to improve the cleanliness of drinking water.

[0050] like Figure 1 In some embodiments of this utility model, the water system 100 further includes a pressure relief component 60, which is connected to the water outlet of the heating component 20. The pressure relief component 60 is configured to open when the water outlet pressure of the heating component 20 is greater than or equal to a preset pressure value. In this way, the safety of the water system 100 can be ensured and damage to the water dispenser can be avoided.

[0051] In detail, the pressure relief component 60 may include a pressure relief flow path 61 and a pressure relief valve 62. The inlet end of the pressure relief flow path 61 is connected to the outlet end of the heating component 20, and the pressure relief valve 62 is installed in the pressure relief flow path 61. When the heating component 20 is working, the heating component 20 heats the water flowing through it, which increases the outlet pressure of the heating component 20. The water pump 12 also applies a driving force to the water flow, which also increases the pressure of the water flow. Therefore, a pressure relief valve 62 and a pressure relief flow path 61 may be provided. When the outlet pressure of the heating component 20 is greater than or equal to a preset pressure value, the valve opens to release the water pressure in the water system 100, thereby preventing the water system 100 from being damaged due to excessive pressure.

[0052] like Figure 1 In some embodiments of this utility model, the water inlet assembly 10 further includes a filter unit 70, which is connected upstream of the negative pressure valve 11. The filter unit 70 is configured to filter the water flowing to the negative pressure valve 11. Specifically, the filter unit 70 is connected upstream of the negative pressure valve 11. After the water flows out from the water source, it can first pass through the filter unit 70. The filter unit 70 filters the impurities carried in the water flow, thereby improving the drinking quality of the hot water.

[0053] In addition, in conjunction with the aforementioned warm water component 50, the filter unit 70 can also be connected upstream of the warm water valve 51. After the water flows out from the water source, it can first pass through the filter unit 70. The filter unit 70 filters the impurities carried in the water flow, thereby improving the drinking quality of the warm water. In other words, after the water flows out from the water source, it can flow to the negative pressure valve 11 according to the user's needs to ultimately provide hot water to the user, or flow to the warm water valve 51 to ultimately provide warm water to the user.

[0054] like Figure 1 In some embodiments of this utility model, the water system 100 further includes a domestic water component 84. The filtration unit 70 includes a first filter element 71 and a second filter element 72 connected in series, and the domestic water component 84 is connected between the first filter element 71 and the second filter element 72. It can be understood that the water system 100 may include a first filter element 71 and a second filter element 72. Through the dual filtration of the first filter element 71 and the second filter element 72, the quality of drinking water can be greatly improved. In addition, the domestic water component 84 may be connected between the first filter element 71 and the second filter element 72. After the water flows through the first filter element 71, it can be discharged from the domestic water component 84 according to the user's needs, thus meeting the user's domestic water usage requirements.

[0055] In practice, the water dispenser is equipped with a raw water interface and a domestic water interface. The raw water interface is used to connect to the water source, and the domestic water interface can be connected to the domestic water component 84. The water source can first flow into the water dispenser and pass through the first filter element 71 inside the water dispenser. Then, it is discharged to the domestic water component 84 through the domestic water interface and water is discharged from the domestic water component 84 to meet the user's domestic water needs.

[0056] like Figure 1 In some embodiments of this utility model, the water system 100 further includes a pressure reducing valve 81, which is connected upstream of the water inlet assembly 10. In conjunction with the foregoing, it can be understood that the water inlet assembly 10 includes a negative pressure valve 11 and a water pump 12. With the cooperation of the negative pressure valve 11 and the water pump 12, the water tank in the water dispenser can be eliminated. In order to further improve the reliability of the tankless water dispenser 1000, a pressure reducing valve 81 can be connected upstream of the water inlet assembly 10. The pressure reducing valve 81 reduces the water pressure of the tap water source, avoiding water pressure fluctuations from affecting the heating assembly 20's regulation of the water flow temperature, thereby further improving the user experience.

[0057] like Figure 1In some embodiments of this utility model, the water system 100 further includes a mechanical leak-proof switch 82, which is connected upstream of the water inlet assembly 10. The mechanical leak-proof switch 82 can be used to prevent leakage of the water system 100. For example, the mechanical leak-proof switch 82 is located at the bottom of the water dispenser. When the water system 100 leaks, the water will overflow at the bottom of the water dispenser, which will trigger the mechanical leak-proof switch 82. The mechanical leak-proof switch 82 will switch the water source, thereby isolating the water source from the water inlet assembly 10 to prevent further overflow and leakage of the water dispenser.

[0058] In some specific examples, the mechanical leakage protection switch 82 includes a switch body, an opening and closing component, and a floating component. The switch body has a flow channel, one end of which is connected to a water source, and the other end is connected to the water inlet assembly 10. The opening and closing component is movably disposed in the flow channel to open and close the flow channel. The opening and closing component is provided with a first magnetic component, and the floating component is provided with a second magnetic component. The floating component can float due to the buoyancy of the leaking water flow in the water dispenser. Through the magnetic cooperation between the second magnetic component and the first magnetic component, the opening and closing component is driven to block the flow channel, thereby realizing the protection function of the mechanical leakage protection switch 82.

[0059] like Figure 1 In some embodiments of this utility model, the water outlet assembly 30 further includes a water outlet 34 and a one-way valve 33. The water outlet 34 is connected to the heating assembly 20, and the one-way valve 34 is connected between the water outlet 33 and the heating assembly 20. It is configured to connect the heating assembly 20 and the water outlet 33 when the pressure of the heating assembly 20 is greater than or equal to a preset pressure value, and to disconnect the heating assembly 20 and the water outlet 33 when the pressure of the heating assembly 20 is less than the preset pressure value. In this way, the heating assembly 20 can heat the water to boiling point to meet the user's hot water needs.

[0060] For example, the water outlet assembly 30 also includes a one-way valve 33 and a water outlet 34. The water outlet 34 is connected to the water outlet end of the first switching valve 32. The one-way valve 33 is connected between the water outlet 34 and the first switching valve 32. The one-way valve 33 can be configured to open the first switching valve 32 and the water outlet 34 when the pressure of the heating assembly 20 is greater than or equal to a preset pressure value, and to disconnect the first switching valve 32 and the water outlet 34 when the pressure of the heating assembly 20 is less than the preset pressure value. In this way, the heating assembly 20 can heat the water to boiling to meet the user's hot water needs.

[0061] Understandably, in related technologies, when the heating component 20 heats the water flow to 90°C, a large amount of steam is generated in the heating component 20, causing water to splash and affecting the user experience. Moreover, the performance of the heating component 20 is limited, and its outlet water temperature does not exceed 95°C. However, in this embodiment, when the heating component 20 is running, the water pump 12 continuously applies pressure to the heating component 20. When the pressure of the heating component 20 is less than the preset pressure value, the one-way valve 33 remains closed, causing the internal pressure of the heating component 20 to build up, i.e., the pressure gradually increases, thereby raising the boiling point of the water flow and allowing the water flow to be heated to above 100°C. Subsequently, the one-way valve 33 opens and releases hot water through the water outlet 34, avoiding water splashing and meeting the user's hot water needs.

[0062] like Figure 1 According to the embodiment of the present utility model, the tankless water dispenser 1000 includes the water circuit system 100 in the above embodiment. By applying the aforementioned water circuit system 100, the low-temperature water in the tankless water dispenser 1000 can be discharged, and the temperature of the first cup of water can be increased, thereby improving the user experience.

[0063] For example, the water outlet assembly 30 includes a water outlet path 31 and a first switch valve 32, and the drainage assembly 40 includes a drainage path 41 and a second switch valve 42. The inlet end of the water outlet path 31 can be connected to the outlet end of the heating assembly 20, and the inlet end of the drainage path 41 can be connected between the outlet end of the heating assembly 20, the outlet end of the heating assembly 20 and the inlet end of the water outlet path 31, or the inlet end of the water outlet path 31. When the user draws hot water again, the first switch valve 32 can be closed to isolate the water outlet path 31, and the second switch valve 42 can be opened to conduct the drainage path 41, so that the low-temperature water at the outlet end of the heating assembly 20 is discharged. When the temperature at the outlet end of the heating assembly 20 reaches a preset value, the first switch valve 32 can be opened to conduct the water outlet path 31, and the second switch valve 42 can be closed to isolate the drainage path 41. At this time, the temperature of the first cup of water drawn by the user meets the requirements.

[0064] The first switching valve 32 and the second switching valve 42 can be controlled in various ways. For example, the switching of the first switching valve 32 and the second switching valve 42 can be controlled by a timing unit. That is, the controller has a timing unit that can calculate the running time of the heating component 20. When the running time of the heating component 20 is less than the preset time, the first switching valve 32 is closed and the second switching valve 42 is opened to discharge the low-temperature water at the outlet of the heating component 20. When the running time of the heating component 20 is greater than or equal to the preset time, the first switching valve 32 is opened and the second switching valve 42 is closed to release the hot water at the outlet of the heating component 20 through the water outlet path 31.

[0065] For example, the opening and closing of the first switch valve 32 and the second switch valve 42 can be controlled by a temperature sensor. The temperature sensor can detect the outlet water temperature of the heating component 20. When the outlet water temperature of the heating component 20 is lower than the preset temperature value, the first switch valve 32 is closed and the second switch valve 42 is opened to discharge the low-temperature water at the outlet of the heating component 20. When the outlet water temperature of the heating component 20 is greater than or equal to the preset temperature value, the first switch valve 32 is opened and the second switch valve 42 is closed to release the hot water at the outlet of the heating component 20 through the outlet flow path 31.

[0066] Furthermore, the water system 100 also includes a warm water component 50, which includes a warm water valve 51 and a sterilization module 52. When the user needs warm water, the water can flow through the warm water valve 51, the sterilization module 52, and the water outlet component 30 to achieve warm water dispensing from the water dispenser. When the user needs hot water, the water can flow through the negative pressure valve 11, the water pump 12, the heating component 20, and the water outlet component 30 to achieve hot water dispensing from the water dispenser.

[0067] Furthermore, the water system 100 also includes a pressure reducing valve 81, a mechanical leak-proof switch 82, a first filter element 71, a domestic water component 84, a second filter element 72, and a flow detection element 83 connected in sequence. The inlet of the pressure reducing valve 81 is connected to a tap water source, and the outlet of the flow detection element 83 is connected to the inlet of the negative pressure valve 11 and the inlet of the hot water valve 51. The pressure reducing valve 81 is located at the front end of the water system 100 to reduce the pressure of the tap water and improve the reliability of the water system 100. The mechanical leak-proof switch... The valve 82 is positioned between the outlet of the pressure reducing valve 81 and the inlet of the first filter element 71 to promptly cut off the flow of water in the subsequent part when the water system 100 leaks, preventing the leak from expanding further. The domestic water component 84 is positioned between the first filter element 71 and the second filter element 72, so that the water flow only needs to pass through the first filter element 71 to meet the needs of domestic water. The flow detection element 83 is used to detect the flow rate in the water system 100 to ensure that the flow rate in the water system 100 is within the preset range and meets the operating requirements of the water dispenser.

[0068] Furthermore, in some specific examples, a solenoid valve is connected between the outlet of the second filter element 72 and the inlet of the flow detection element 83. This solenoid valve controls the flow between the outlet of the second filter element 72 and the inlet of the flow detection element 83, thereby controlling the water intake of the heating element 20 and the warm water element 50, further improving the reliability of the water system 100 and preventing water pressure from impacting the water system 100. Additionally, in other specific examples, a capacitive sensor is connected between the outlet of the negative pressure valve 11 and the inlet of the water pump 12. This capacitive sensor can detect whether there is water flow in the pipeline. The heating element 20 can only operate when the capacitive sensor detects water flow, preventing the heating element 20 from burning dry and further improving the safety of the water system 100. In still other specific examples, the outlet of the water element 30 is equipped with a water spout 34, which can be used to dispense water from the water dispenser.
