Description

Technical Field

[0001] This application relates to the field of drinking water treatment technology, and in particular to a drinking water system and a water dispenser. Background Technology

[0002] With the development of science and technology and the improvement of people's living standards, people's awareness of healthy drinking water has gradually increased, and their requirements for drinking water quality are becoming higher and higher. Water purifiers with water purification functions have emerged as a result. To meet users' needs for hot water, instant hot water faucets can be added to water purifiers to create integrated purification and heating systems.

[0003] However, in scenarios such as high temperatures in summer, users will still have a need for drinking cold water, and existing integrated water purifiers and heaters cannot meet the needs for both cold and hot drinking water. Utility Model Content

[0004] Therefore, it is necessary to provide a drinking water system and water dispenser to address the problem that integrated water purifiers and heaters cannot simultaneously meet the needs for both cold and hot drinking water.

[0005] This application provides a drinking water system, including: a water outlet component, a water supply component, a heat exchange component, a first water storage component, a water pump component, a heating component, a second water storage component, a cooling component, and a control component. The water supply component is used to deliver pure water. The heat exchange component includes a first water path and a second water path capable of heat exchange. The inlet of the first water path is connected to the outlet of the water supply component. The inlet of the first water storage component is connected to the outlet of the first water path, and the replenishment port of the first water storage component is connected to the outlet of the water supply component. The outlet of the first water storage component is connected to the water pump component. The heating component has an inlet; its inlet is connected to the outlet of the water pump component; its outlet is connected to the inlet of the second water path and the outlet component; the outlet of the second water path is connected to the outlet component; the inlet of the second water storage component is connected to the outlet of the water supply component; the outlet of the second water storage component is connected to the inlet of the cooling component; the outlet of the cooling component is connected to the inlet of the water pump component; the first water storage component, the water pump component, the heating component, the second water storage component, and the cooling component are respectively connected to the control component.

[0006] The aforementioned drinking water system is equipped with a heating component, a heat exchange component, and a cooling component. When a user needs hot water, the control component activates the water pump and heating components to heat the hot water stored in the first and / or second water storage components to boiling water, which is then output through the outlet component. When a user needs boiled water, the control component activates the water pump and heating components to heat the hot water stored in the first and / or second water storage components to boiling water. This boiled water then enters the heat exchange component through the second water path, where it exchanges heat with the cold water flowing in through the first water path, thus being cooled to the target temperature and output through the outlet component. When a user needs cold water, the control component activates the water pump and cooling components to draw water stored in the second water storage component to the cooling component for cooling, ultimately obtaining the target temperature cold water, which is then output. Through this scheme, the drinking water system can not only output hot and boiled water but also cold water according to user needs, thus catering to both hot and cold drinking water requirements and possessing strong applicability.

[0007] In one embodiment, the first water storage component includes a first water storage tank, and a first temperature detector and a first liquid level detector disposed inside the first water storage tank, wherein the first temperature detector and the first liquid level detector are respectively connected to the control component;

[0008] And / or, the second water storage component includes a second water storage tank, and a second temperature detector and a second liquid level detector disposed inside the second water storage tank, the second temperature detector and the second liquid level detector being respectively connected to the control component.

[0009] The above scheme includes a water storage tank, a temperature detector and a liquid level detector in the first and / or second water storage components, which can monitor the internal water level and water temperature, ensuring the amount of water stored while maintaining the water temperature and improving the reliability of water storage.

[0010] In one embodiment, the water pump assembly includes a water pump, and the drinking water system further includes a first double-way switch.

[0011] In the above scheme, by setting the first double-switch, the first water storage component and the second water storage component can share a water path. Hot water (including boiled water and hot water) and cold water of the drinking water system are transported through a single water path, which not only reduces the system size but also effectively reduces hardware costs.

[0012] In one embodiment, the drinking water system further includes a water replenishment branch, a second double-way switch, and a water replenishment switch disposed on the water replenishment branch. The inlet of the water replenishment branch is connected to the outlet of the water supply component, the outlet of the water replenishment branch is connected to the inlet of the second double-way switch, the first outlet of the second double-way switch is connected to the water replenishment port of the first water storage component, the second outlet of the second double-way switch is connected to the inlet of the second water storage component, and the water replenishment switch and the second double-way switch are respectively connected to the control component.

[0013] The above solution, through the setting of water replenishment branch, second double-pass switch and water replenishment switch, allows the first water storage component and the second water storage component to share a water circuit for water replenishment, which can also reduce the system size and reduce hardware costs.

[0014] In one embodiment, the drinking water system further includes a return water pipe, the first end of which is connected between the outlet of the heating component and the outlet component, and the second end of which is connected to the inlet of the second double-pass switch.

[0015] The above solution, through the setting of the return water pipeline, allows heated hot water to flow back to the first and / or second water storage components for storage, ensuring the hot water temperature stored in the first and / or second water storage components, thereby achieving an instantaneous large-flow hot water supply when hot water is needed. Simultaneously, the return water pipeline also allows pure water output from the supply components to be directly delivered to the outlet components, thus meeting the user's need for room temperature water.

[0016] In one embodiment, the drinking water system further includes a third double-way switch and a fourth double-way switch. The first inlet of the third double-way switch is connected to the outlet of the heating component, the second inlet of the third double-way switch is connected to the outlet of the second water circuit, the outlet of the third double-way switch is connected to the inlet of the fourth double-way switch, the first outlet of the fourth double-way switch is connected to the first end of the return water pipe, the second outlet of the fourth double-way switch is connected to the water outlet component, and the third and fourth double-way switches are respectively connected to the control component.

[0017] The above scheme, through the setting of the third and fourth double-pass switches, can realize the control of water flow direction in different modes, ensure the reliable operation of each mode, and improve the operational reliability of the drinking water system.

[0018] In one embodiment, the drinking water system further includes a check valve and / or a third temperature detector, the check valve being disposed in the first water path, the third temperature detector being disposed at the outlet of the third double-way switch, and the third temperature detector being connected to the control component.

[0019] The above solution, by setting a check valve, prevents water from flowing back into the heating element from the second water circuit. A third temperature detector is installed at the outlet of the third double-way switch to monitor the outlet water temperature. This allows for recirculation heating and other operations when the output hot water temperature does not meet the user's needs, thereby improving the accuracy of hot water output.

[0020] In one embodiment, the drinking water system further includes a two-inlet, two-outlet switch, wherein the first inlet of the two-inlet, two-outlet switch is connected to the outlet of the heating component, the second inlet of the two-inlet, two-outlet switch is connected to the outlet of the second water circuit, the first outlet of the two-inlet, two-outlet switch is connected to the first end of the return water pipe, the second outlet of the two-inlet, two-outlet switch is connected to the water outlet component, and the two-inlet, two-outlet switch is connected to the control component.

[0021] The above solution, through the configuration of two inlet and two outlet switches, enables control of water flow direction under different modes, reduces the number of switches at the water outlet component, and reduces the system size to a certain extent.

[0022] In one embodiment, the drinking water system further includes a flow regulating component and / or a flow detection component connected to the control component, wherein the inlet of the first water path is connected to the outlet of the water supply component through the flow regulating component, and the flow detection component is disposed at the inlet of the water pump component.

[0023] The above solution, through the setting of flow regulation components and / or flow detection components, can adjust the flow rate of cold water input to the first water channel, or monitor and adjust the flow rate of water delivered to the heating component for heating, thereby ensuring the accuracy of the output temperature of boiled water in boiled water mode.

[0024] In one embodiment, the cooling assembly includes a cooler, a water-cooled radiator, and a fourth temperature detector. The cooler is disposed on the outer surface of the water-cooled radiator. The inlet of the water-cooled radiator is connected to the outlet of the second water storage assembly, the outlet of the water-cooled radiator is connected to the inlet of the water pump assembly, and the fourth temperature detector is disposed at the outlet of the water-cooled radiator. The cooler and the fourth temperature detector are respectively connected to the control assembly.

[0025] The above solution uses a cooler, a water-cooled radiator, and a fourth temperature detector to form a cooling component. It can not only achieve cooling operation, but also monitor the water temperature of the cooled water after cooling, ensuring that the final output water temperature meets the user's needs and has high reliability in cooling operation.

[0026] In one embodiment, the cooler is a semiconductor cooler.

[0027] The above solution uses a semiconductor cooler for cooling, which reduces the noise of the water system during operation and can also reduce the size of the cooling components to a certain extent, allowing the water system to be installed under the sink where space is limited.

[0028] In one embodiment, the water supply assembly includes a water purification device, the inlet of which is used to input raw water, and the outlet of which is used to deliver pure water.

[0029] The above solution uses a water purification device with water purification function as a water supply component, which enables the drinking water system to be operated with raw water and improves the applicability of the drinking water system.

[0030] This application also provides an operation method based on the above-mentioned drinking water system, the operation method comprising: obtaining the operation mode of the drinking water system; when the operation mode is boiling water mode, controlling the water pump assembly and the heating assembly to start operation, so as to heat the hot water stored in the first water storage assembly and / or the second water storage assembly to boiling water, and then output it through the water outlet assembly; when the operation mode is cooked water mode, controlling the water pump assembly and the heating assembly to start operation, so as to heat the water stored in the first water storage assembly and / or the second water storage assembly to boiling water, and then deliver it to the heat exchange assembly to cool it to the target temperature cooked water, and then output it through the water outlet assembly; when the operation mode is cold water mode, controlling the water pump assembly and the cooling assembly to start operation, so as to cool the water stored in the second water storage assembly to the target temperature cold water, and then output it through the water outlet assembly.

[0031] The above-mentioned solution allows the drinking water system to output not only boiled and cooked water, but also cold water according to user needs, thus taking into account users' needs for both hot and cold drinking water and having strong applicability.

[0032] In one embodiment, the drinking water system further includes a water replenishment branch, a second double-pass switch, and a water replenishment switch. The operating method further includes: when the water level of the first water storage component and / or the second water storage component is lower than a preset water level threshold, controlling the water replenishment switch and the second double-pass switch to start operation to replenish water to the first water storage component and / or the second water storage component.

[0033] The above solution can replenish water to the first and / or second water storage components when the water level is low, ensuring the water storage capacity of the first and / or second water storage components.

[0034] In one embodiment, the drinking water system further includes a return water pipeline, and the operating method further includes: in standby mode, acquiring a first water temperature of the first water storage component and / or a second water temperature of the second water storage component; when the first water temperature is less than a preset heat preservation threshold, controlling the water pump component and the heating component to start operation, so as to circulate and heat the hot water stored in the first water storage component to the preset heat preservation threshold for storage; when the second water temperature is less than the preset heat preservation threshold, controlling the water pump component and the heating component to start operation, so as to circulate and heat the hot water stored in the second water storage component to the preset heat preservation threshold for storage.

[0035] In the standby mode, when the water temperature of the first water storage component and / or the second water storage component is detected to be too low, the hot water stored in the first water storage component and / or the second water storage component can be circulated and heated to maintain the hot water temperature of the first water storage component and / or the second water storage component, ensuring that when there is a demand for hot water, the hot water can be heated to boiling water in a shorter time.

[0036] In one embodiment, the operating method further includes: when a preset cooling shutdown condition is met, controlling the water pump assembly and the heating assembly to start operation, so as to circulate and heat the cold water stored in the second water storage assembly to a preset heat preservation threshold for storage.

[0037] The above solution can automatically switch to the second water storage component to store hot water when the cooling of the drinking water system is turned off. When there is a need for hot water later, hot water can be provided in the form of dual hot water tanks for heating, further increasing the amount of hot water available.

Detailed Implementation

[0051] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of this application.

[0052] Please see Figure 1This application provides a drinking water system, including: a water outlet component 10, a water supply component 20, a heat exchange component 30, a first water storage component 40, a water pump component 50, a heating component 60, a second water storage component 70, a cooling component 80, and a control component (not shown). The water supply component 20 is used to transport pure water; the heat exchange component 30 includes a first water path and a second water path capable of heat exchange, the inlet of the first water path (Figure 31) is connected to the outlet of the water supply component 20; the inlet of the first water storage component 40 is connected to the outlet of the first water path (Figure 32), and the water replenishment port of the first water storage component 40 is connected to the outlet of the water supply component 20; the water outlet of the first water storage component 40... The inlet of the water pump assembly 50 is connected to the outlet of the water pump assembly 50; the outlet of the heating assembly 60 is connected to the inlet of the second water path (Figure 33) and the outlet assembly 10; the outlet of the second water path (Figure 34) is connected to the outlet assembly 10; the inlet of the second water storage assembly 70 is connected to the outlet of the water supply assembly 20; the outlet of the second water storage assembly 70 is connected to the inlet of the cooling assembly 80; the outlet of the cooling assembly 80 is connected to the inlet of the water pump assembly 50; the first water storage assembly 40, the water pump assembly 50, the heating assembly 60, the second water storage assembly 70 and the cooling assembly 80 are respectively connected to the control assembly (not shown).

[0053] Specifically, the water outlet component 10 is the end device used to dispense water, such as a faucet. In practical scenarios, it can be a mechanical water outlet component 10 or an electronic water outlet component 10; there is no specific limitation. The number of water outlet components 10 is not unique; there can be one or multiple. That is, boiling water, cooked water, cold water, and room temperature water can be dispensed through one water outlet component 10, or different water outlet components 10 can be configured for dispensing water; there is no specific limitation.

[0054] The water supply component 20 is a device used to provide pure water, which is water that has undergone physical or chemical methods to remove impurities, reaching a specific purity standard and is directly drinkable. The type of water supply component 20 is not unique; the selected component will vary depending on the application scenario of the drinking water system or the quality of the input water. In one embodiment, the water supply component 20 inputs drinkable water, in which case it only needs to include a delivery device (e.g., a pressure-stabilizing pump). In another embodiment, the water supply component 20 inputs non-drinkable water (i.e., raw water), in which case it may include a water purification device to purify the input raw water into pure water before outputting it.

[0055] The heat exchange component 30 is a device that exchanges heat between the boiling water heated by the heating component 60 and the room-temperature pure water output by the water supply component 20. It can heat the boiling water to obtain cooked water and heat the room-temperature pure water to hot water with a certain temperature. Cooked water refers to water that has been heated to boiling water (i.e., boiling water, which can be 100 degrees Celsius, or less or greater than 100 degrees Celsius depending on the altitude), and then cooled down to obtain hot water, the temperature of which is usually higher than that of room-temperature water.

[0056] In the heat exchange assembly 30, the configuration of the first and second water channels is not unique; they can be connected through contact using a thermally conductive material. Please refer to the relevant documentation. Figure 2 The system can be configured with inner and outer pipes, with the first water path serving as the inner pipe and the second water path as the outer pipe, or vice versa. In other embodiments, it can also be an immersion system, where the second water path is immersed in the first water path, or vice versa. The specific configuration is not limited, as long as heat exchange between the water flowing through the two water paths is ensured.

[0057] The first water storage component 40 is a device for storing and heating the hot water output from the first water path of the heat exchange component 30, or the pure water output from the water supply component 20. The second water storage component 70 is a device for storing and heating the pure water output from the water supply component 20 into hot water, or for storing and heating the cold water obtained from the cooling component 80. The cooling component 80 is a device that can cool the water supplied to it and output it through heat exchange. The heating component 60 is a device that heats the water supplied to it and outputs it.

[0058] In practical scenarios, depending on the needs, the second water storage component 70 can store either cold or hot water. Specifically, in cold water mode, the drinking water system activates its cooling function. The water stored in the second storage component is cooled to the target temperature through circulation and then stored. When the user opens the water outlet component 10, the water can be directly dispensed to the user. When the preset cooling shutdown conditions are met, the water stored in the second storage component is heated to a certain temperature through circulation and stored as hot water. This allows for the provision of more hot water for heating when the user needs hot water (including boiled and cooked water), meeting the demand for large-flow hot water.

[0059] The control component, also known as the water supply system, is used to control the operation of the first water storage component 40, the second water storage component 70, the water pump component 50, the heating component 60, and the cooling component 80 according to user instructions or user needs, in order to achieve a large flow of hot or cold water supply. Its type is not unique; it can be a microcontroller unit, etc., and there is no specific limitation.

[0060] The type of heating component 60 is not unique; its structure may vary depending on the heating method. In one embodiment, the heating component 60 is an instantaneous heating component 60, which includes a power-adjustable heating element to heat the flowing water to different temperatures. The type of heating element is not unique; for example, it may be a PTC (Positive Temperature Coefficient) heating element, a rare-earth thick-film heating element, or a metal heating tube, etc., and is not specifically limited.

[0061] In boiling water mode, the control unit activates the water pump assembly 50 and the heating assembly 60. The water pump assembly 50 draws hot water stored in the first water storage assembly 40 and / or the second water storage assembly 70 to the heating assembly 60 for heating into boiling water, which is then directly supplied to the water outlet assembly 10 for the user. It can be understood that the boiling water does not pass through the heat exchange assembly 30 at this time, and the cooling assembly 80 is not activated. The water flow direction can be controlled by setting switches or other methods in the water passages between the various components; the specific method is not limited.

[0062] In the boiled water mode, the water pump assembly 50 and heating assembly 60 are also activated. The water pump assembly 50 draws hot water stored in the first water storage assembly 40 and / or the second water storage assembly 70 to the heating assembly 60 for heating into boiling water. This boiling water then passes through the second water path of the heat exchange assembly 30, exchanging heat with the ambient temperature water flowing through the first water path. This cools the water to the target temperature before it is output from the outlet assembly 10, achieving an instantaneous, high-flow-rate boiled water supply. The ambient temperature water in the first water path is heated to hot water and flows into the first water storage assembly 40, where it is further heated into boiling water. Similarly, the cooling assembly 80 is not activated at this time. The water flow direction is controlled by switches or other means installed in the water paths between the various components; the specific method is not limited.

[0063] In cold water mode, the control component activates the water pump assembly 50 and the cooling assembly 80. At this time, the heating assembly 60 is off, and the water flow does not pass through the heat exchange assembly 30. In one embodiment, the water pump assembly 50 draws water stored in the second water storage assembly 70 to the cooling assembly 80, directly cooling it to the target temperature before outputting it through the outlet assembly 10. In another embodiment, the water pump assembly 50 draws water stored in the second water storage assembly 70 to the cooling assembly 80 to lower its temperature, then returns it to the second water storage assembly 70. Through this cyclical cooling process, the water is ultimately cooled to the target temperature and stored in the second water storage assembly 70. When the user requires it, the target temperature cold water is directly output. It is understood that in cold water mode, the water flow direction can also be controlled by setting switches or other methods in the water path between the components, which will not be elaborated upon here.

[0064] The aforementioned drinking water system is equipped with a heating component 60, a heat exchange component 30, and a cooling component 80. When a user needs hot water, the control component activates the water pump component 50 and the heating component 60 to heat the hot water stored in the first water storage component 40 and / or the second water storage component 70 to boiling water, which is then output through the water outlet component 10. When a user needs boiled water, the control component activates the water pump component 50 and the heating component 60 to heat the hot water stored in the first water storage component 40 and / or the second water storage component 70 to boiling water. This boiled water then enters the heat exchange component 30 through the second water path, where it exchanges heat with the cold water flowing in through the first water path, thus being cooled to the target temperature and output from the water outlet component 10. When a user needs cold water, the control component activates the water pump component 50 and the cooling component 80 to draw water stored in the second water storage component 70 to the cooling component 80 for cooling, ultimately obtaining cold water at the target temperature, which is then output. With the above solution, the drinking water system can not only output boiled and cooked water, but also output cold water according to user needs, while taking into account users' needs for both hot and cold drinking water, and has strong applicability.

[0065] In one embodiment, the first water storage component 40 includes a first water storage tank, and a first temperature detector and a first liquid level detector disposed inside the first water storage tank, the first temperature detector and the first liquid level detector being respectively connected to a control component.

[0066] And / or, in one embodiment, the second water storage component 70 includes a second water storage tank, and a second temperature detector and a second liquid level detector disposed inside the second water storage tank, the second temperature detector and the second liquid level detector being respectively connected to a control component.

[0067] Specifically, the first water storage component 40 and the second water storage component 70 have similar structures, each including a water tank, a temperature detector, and a level detector. The temperature detector monitors the water temperature inside the tank, and the level detector monitors the water level inside the tank. Thus, when the water temperature is too low, the circulating heating function can be activated to ensure the stored hot water temperature. Alternatively, when the water level is too low, water can be added to ensure the stored water volume. In cooling mode, if the water temperature in the second water storage component 70 is detected to be too high, the circulating cooling function can be activated to maintain the temperature of the cold water stored in the second water storage component 70.

[0068] It should be noted that, in one embodiment, considering the need for heat preservation in the water tank, heat-insulating materials can be used to construct the water tank. In another embodiment, heat preservation can also be applied to the exterior of the water tank, such as by installing an insulation layer, etc., and the specific method is not limited.

[0069] In the above scheme, the first water storage component 40 and / or the second water storage component 70 are configured to include a water storage tank, a temperature detector and a liquid level detector, so as to monitor the internal water level and water temperature, ensuring the amount of water stored while also maintaining the water temperature and improving the reliability of water storage.

[0070] Please see Figure 3 In one embodiment, the water pump assembly 50 includes a water pump (Figure 51), and the drinking water system also includes a first double-way switch 11. The outlet of the first water storage assembly 40 is connected to the first inlet of the first double-way switch 11, the outlet of the second water storage assembly 70 is connected to the second inlet of the first double-way switch 11, the outlet of the first double-way switch 11 is connected to the inlet of the water pump assembly 50, and the first double-way switch 11 is connected to a control assembly (not shown).

[0071] Specifically, in this embodiment, the first water storage component 40 and the second water storage component 70 share a water pump. When the control component controls the first inlet and outlet of the first double-way switch 11 to connect, the water pump can extract the hot water stored in the first water storage component 40. When the control component controls the second inlet and outlet of the first double-way switch 11 to connect, the water pump can extract the hot or cold water stored in the second water storage component 70. When the control component controls both the first inlet and outlet of the first double-way switch 11 to connect, the water pump can simultaneously extract the hot water stored in both the first water storage component 40 and the second water storage component 70.

[0072] It should be noted that the type of water pump is not unique. In one embodiment, it can be a self-priming water pump, while in other embodiments, other types of water pumps may be used. No specific limitation is made.

[0073] The type of the first double-way switch 11 is not unique. In one embodiment, it can be a two-inlet-one-outlet solenoid valve. In another embodiment, two solenoid valves can be used to form the first double-way switch 11. In this case, the inlets of the two solenoid valves are respectively used as the first inlet and the second inlet, and the outlets of the two solenoid valves are connected to serve as the outlet of the first double-way switch 11.

[0074] In the above scheme, by setting the first double-switch 11, the first water storage component 40 and the second water storage component 70 can share a water path. Hot water (including boiled water and hot water) and cold water of the drinking water system are transported through a water path, which can not only reduce the system size, but also effectively reduce hardware costs.

[0075] In another embodiment, the water pump assembly 50 may further include two water pumps. The first water storage assembly 40 and the second water storage assembly 70 are each connected to one water pump, and the outlets of both water pumps are connected to the heating assembly 60, thus sharing a single output water path, eliminating the need for the first double-pass switch 11. In another embodiment, the water path may not be shared. The first water storage assembly 40 is connected to the inlet of the heating assembly 60 via a water pump, while the second water storage assembly 70 is directly connected to the outlet assembly 10 via a water pump.

[0076] Please see Figure 4 In one embodiment, the drinking water system further includes a water replenishment branch 41, a second double-way switch 12, and a water replenishment switch 42 disposed on the water replenishment branch 41. The inlet of the water replenishment branch 41 is connected to the outlet of the water supply component 20, the outlet of the water replenishment branch 41 is connected to the inlet of the second double-way switch 12, the first outlet of the second double-way switch 12 is connected to the water replenishment port of the first water storage component 40, the second outlet of the second double-way switch 12 is connected to the inlet of the second water storage component 70, and the water replenishment switch 42 and the second double-way switch 12 are respectively connected to a control component (not shown).

[0077] Specifically, the water supply branch 41 is the pipeline used to replenish pure water to the first water storage component 40 and the second water storage component 70, and the water supply switch 42 is the switch used to control the water supply to be turned on and off. Its type is not unique and can be a solenoid valve, etc., and is not specifically limited. In this embodiment, the first water storage component 40 and the second water storage component 70 share a water supply branch 41. The end of the water supply branch 41 is split through the second double-way switch 12, so that pure water can be delivered to the first water storage component 40 or the second water storage component 70.

[0078] Similarly, the type of the second double-way switch 12 is not unique; it can be a one-in-two-out solenoid valve or two solenoid valves connected in parallel, without any specific limitation.

[0079] The above solution, through the setting of water replenishment branch 41, second double-pass switch 12 and water replenishment switch 42, allows the first water storage component 40 and the second water storage component 70 to share a water circuit for water replenishment, which can also reduce the system size and reduce hardware costs.

[0080] In another embodiment, two water supply branches 41 can be provided. The two water supply branches 41 are respectively connected to the outlet of the water supply component 20. One water supply branch 41 is connected to the first water storage component 40, and the other water supply branch 41 is connected to the second water storage component 70. Each of the two water supply branches 41 is provided with a water supply switch 42. In this case, there is no need to configure the second double-pass switch 12 to independently realize the water supply of the two water storage components.

[0081] Please continue reading. Figure 4In one embodiment, the drinking water system further includes a return water pipe 43, the first end of which is connected between the outlet of the heating component 60 and the outlet component 10, and the second end of which is connected to the inlet of the second double-pass switch 12.

[0082] Specifically, the return water pipe 43 is connected between the inlet of the two double-pass switch and the water storage component. Thus, when the user needs room temperature water, the room temperature water output by the water supply component 20 flows into the return water pipe 43 through the water replenishment branch 41 and is delivered to the water outlet component 10 through the first end of the return water pipe 43.

[0083] In the case of circulating heating, the heated water can be returned to the first water storage component 40 and / or the second water storage component 70 through the return water pipe 43; in the case of circulating cooling, the cooled cold water can be returned to the second water storage component 70 through the return water pipe.

[0084] The above solution, through the setting of the return water pipe 43, allows heated hot water to flow back to the first water storage component 40 and / or the second water storage component 70 for storage, ensuring the temperature of the hot water stored in the first water storage component 40 and / or the second water storage component 70, thereby achieving a large-flow hot water supply instantly when hot water is needed. At the same time, through the setting of the return water pipe 43, the pure water output from the water supply component 20 can also be directly delivered to the water outlet component 10, thereby meeting the user's demand for room temperature water.

[0085] Please see Figure 5 In one embodiment, the drinking water system further includes a third double-way switch 13 and a fourth double-way switch 14. The first inlet of the third double-way switch 13 is connected to the outlet of the heating component 60, the second inlet of the third double-way switch 13 is connected to the outlet of the second water circuit, the outlet of the third double-way switch 13 is connected to the inlet of the fourth double-way switch 14, the first outlet of the fourth double-way switch 14 is connected to the first end of the return water pipe 43, the second outlet of the fourth double-way switch 14 is connected to the water outlet component 10, and the third double-way switch 13 and the fourth double-way switch 14 are respectively connected to a control component (not shown).

[0086] Specifically, the types of the third double-way switch 13 and the fourth double-way switch 14 are not unique. They can be one-in-two-out solenoid valves or two-in-one-out solenoid valves as described in the above embodiments, or two solenoid valves connected in parallel, or other types of switches. No specific limitation is imposed.

[0087] In hot water mode or cold water mode, the control component controls the first inlet and outlet of the third double-switch 13 to connect, and controls the inlet and outlet of the fourth double-switch 14 to connect, so that hot water (or cold water) is output by the water outlet component 10 after passing through the first double-switch 11 and the second double-switch 12.

[0088] In the boiled water mode, the control component controls the second inlet and outlet of the third double-switch 13 to connect, and controls the inlet and outlet of the fourth double-switch 14 to connect, so that after boiling water flows into the heat exchange component 30 to exchange heat and obtain boiled water, the boiled water passes through the first double-switch 11 and the second double-switch 12 in sequence, and is finally output by the water outlet component 10.

[0089] In the circulating heating or circulating cooling mode, the control component controls the first inlet and outlet of the third double-way switch 13 to connect, and controls the inlet and first outlet of the fourth double-way switch 14 to connect, so that hot water (or cold water) passes through the first double-way switch 11 and the second double-way switch 12 in sequence, flows into the return water pipe, and finally flows back to the first water storage component 40 and / or the second water storage component 70.

[0090] The above scheme, through the setting of the third double-pass switch 13 and the fourth double-pass switch 14, can realize the control of water flow direction in different modes, ensure the reliable operation of each mode, and improve the operational reliability of the drinking water system.

[0091] Please refer to the following: Figure 5 In one embodiment, the drinking water system further includes a check valve 52 and / or a third temperature detector 53. The check valve 52 is located in the first water path, and the third temperature detector 53 is located at the outlet of the third double-way switch 13. The third temperature detector 53 is connected to the control component.

[0092] Specifically, the check valve 52 is a device that allows the medium (such as water) to flow in one direction and closes when the medium flows in the opposite direction. By setting the check valve 52, water from the heat exchange component 30 is prevented from flowing back into the heating component 60. By setting the third temperature detector 53, when the water temperature output from the outlet of the third double-way switch 13 does not meet the requirements (such as the water temperature is too low), the third double-way switch 13 is activated to recirculate the water for heating, so as to ensure that the final output water temperature meets the requirements. In this way, zero cold water output can be achieved.

[0093] The above solution, by setting the check valve 52, prevents the water in the second water circuit from flowing back to the heating component 60. The third temperature detector 53 is configured at the outlet of the third double-way switch 13 to monitor the outlet water temperature. This allows for recirculation heating and other operations when the output hot water temperature does not meet the user's needs, thereby improving the accuracy of hot water output.

[0094] Please see Figure 6In one embodiment, the drinking water system further includes a two-inlet two-outlet switch 61. The first inlet of the two-inlet two-outlet switch 61 is connected to the outlet of the heating component 60, the second inlet of the two-inlet two-outlet switch 61 is connected to the outlet of the second water circuit, the first outlet of the two-inlet two-outlet switch 61 is connected to the first end of the return water pipe 43, the second outlet of the two-inlet two-outlet switch 61 is connected to the water outlet component 10, and the two-inlet two-outlet switch 61 is connected to the control component.

[0095] Specifically, unlike the third double-pass switch 13 and the fourth double-pass switch 14 in the above embodiments, this embodiment can use a two-in-two-out switch 61 to replace the third double-pass switch 13 and the fourth double-pass switch 14 to achieve water flow control. The specific choice can be made according to actual needs.

[0096] The two-inlet, two-outlet switch 61 is a switching device that has two water inlets and two water outlets, and can control the connection between one of the inlets and one of the outlets according to actual needs. For example, in one embodiment, in hot water mode or cold water mode, the first inlet of the two-inlet, two-outlet switch 61 can be connected to the second outlet; in boiled water mode, the second inlet of the two-inlet, two-outlet switch 61 can be connected to the second outlet; in circulating heating or circulating cooling mode, the first inlet of the two-inlet, two-outlet switch 61 can be connected to the first outlet.

[0097] The above solution, through the configuration of two inlet and two outlet switches 61, enables control of water flow direction under different modes, reduces the number of switches at the water outlet component 10, and reduces the system size to a certain extent.

[0098] Please see Figure 7 In one embodiment, the drinking water system further includes a flow regulating component 71 and / or a flow detection component 72 connected to the control component. The inlet of the first water path is connected to the outlet of the water supply component 20 through the flow regulating component 71, and the flow detection component 72 is located at the inlet of the water pump component 50.

[0099] Specifically, the flow regulation component 71 is a device capable of regulating the flow rate of room temperature water supplied to the first water path. Its type is not unique; it can be a flow regulating valve, or in other embodiments, a pressure reducing valve and a water pump connected in series. No specific limitation is made. The flow detection component 72 monitors the water flow rate input to the heating element, thereby allowing feedback adjustment of the power of the water pump component 50, which in turn changes the flow rate of boiling water input to the second water path in the boiled water mode. Ultimately, by adjusting the flow rate of room temperature water in the first water path and / or the flow rate of boiling water in the second water path, various boiled water temperatures can be output to meet different user needs for boiled water temperature.

[0100] The above solution, through the setting of the flow regulation component 71 and / or the flow detection component 72, can adjust the flow rate of cold water input to the first water path, or monitor and adjust the flow rate of water supplied to the heating component 60 for heating, thereby ensuring the accuracy of the output temperature of boiled water in boiled water mode.

[0101] In one embodiment, the cooling assembly 80 includes a cooler, a water-cooled radiator, and a fourth temperature detector. The cooler is disposed on the outer surface of the water-cooled radiator. The inlet of the water-cooled radiator is connected to the outlet of the second water storage assembly 70, the outlet of the water-cooled radiator is connected to the inlet of the water pump assembly 50, and the fourth temperature detector is disposed at the outlet of the water-cooled radiator. The cooler and the fourth temperature detector are respectively connected to the control assembly.

[0102] Specifically, the type of the cooling component 80 is not unique. In this embodiment, heat exchange is used, where the cooler generates cold air that carries away the water flowing through the water-cooling radiator, thereby lowering the water temperature. When the cooling function is activated, the cooler begins to dissipate heat and lower the temperature. At this time, the water pump component 50 simultaneously starts pumping water into the water-cooling radiator, carrying away the cold energy generated by the cooling module and circulating it into the second water storage component 70. Since the second water storage component 70 is equipped with a second temperature detector, when the cold water temperature in the second water storage component 70 reaches the user-set or factory default cold water temperature, the cooling cycle stops and enters the heat preservation mode. When the water temperature rises to a certain level (such as rising to the ambient temperature / or room temperature of 25°C), the cooling cycle will restart, or it can be manually started upon receiving a user command.

[0103] The above solution uses a cooler, a water-cooled radiator, and a fourth temperature detector to form a cooling component 80. This not only enables cooling operations but also monitors the temperature of the cooled water to ensure that the final output water temperature meets user requirements, thus providing high reliability in cooling operation.

[0104] In one embodiment, the cooler is a semiconductor cooler.

[0105] Specifically, the cooling method is not unique. This embodiment uses semiconductor cooling, which utilizes the Peltier effect to generate a temperature difference when current passes through a semiconductor material, thus achieving cooling. It is understood that in other embodiments, a heat sink (such as a fan) can be configured for the cooling component 80 to assist in heat dissipation; the choice can be made based on actual needs.

[0106] It is understood that in other embodiments, methods such as compressor refrigeration can also be used to cool the water, and no specific method is limited.

[0107] The above solution uses a semiconductor cooler for cooling, which reduces the noise of the water system during operation and can also reduce the size of the cooling component 80 to a certain extent, allowing the water system to be installed under the sink where space is limited.

[0108] Please see Figure 8 In one embodiment, the water supply assembly 20 includes a water purification device, the inlet of which is used to input raw water, and the outlet of which is used to deliver pure water.

[0109] Specifically, a water purification device is a device that can purify raw water into pure water that can be drunk directly. There is no single type of device; you can choose one based on your actual needs.

[0110] In one embodiment, such as Figure 8 As shown, the water purification device may include a reverse osmosis (RO) membrane filter, a composite filter, a pressure-stabilizing pump, four solenoid valves, a check valve, a flow meter, two TDS (Total Dissolved Solids) probes, a temperature sensor, etc., the specific components of which are not limited. This water purification device can be connected to tap water or other raw water sources. After passing through the pressure-reducing valve, the water flows into the composite filter for pre-treatment, filtering out impurities. Under the pressure boosting action of the pressure-stabilizing pump, the water pre-treated by the composite filter enters the RO reverse osmosis filter for secondary filtration. The filtered water then flows back to the composite filter, where it undergoes post-filter carbon rod adsorption to remove odors before flowing out from the pure water outlet, supplying subsequent heating, cooling, or direct drinking water. The flow meter, TDS probes, and temperature sensor monitor the water quality during the purification process; details are not elaborated here.

[0111] The above solution uses a water purification device with water purification function as the water supply component 20, which enables the drinking water system to be operated with raw water and improves the applicability of the drinking water system.

[0112] Please see Figure 9 This application also provides an operation method based on the above-mentioned drinking water system, which includes steps 902, 904, 906 and 908.

[0113] Step 902: Obtain the operating mode of the drinking water system.

[0114] Step 904: When the operating mode is boiling water mode, control the water pump assembly and heating assembly to start operation, so as to heat the hot water stored in the first water storage assembly and / or the second water storage assembly into boiling water, and then output it through the water outlet assembly.

[0115] Step 906: When the operating mode is boiled water mode, control the water pump assembly and heating assembly to start operation, so as to heat the water stored in the first water storage assembly and / or the second water storage assembly into boiling water, and then deliver it to the heat exchange assembly to cool it down to the target temperature boiled water, and then output it through the water outlet assembly.

[0116] Step 908: When the operating mode is cold water mode, control the water pump assembly and the cooling assembly to start operation, so as to cool the water stored in the second water storage assembly to the target temperature of cold water, and then output it through the water outlet assembly.

[0117] Specifically, the drinking water system is as shown in the above embodiments and accompanying drawings, and will not be described again here. In hot water mode, the control component controls the water pump component 50 and the heating component 60 to start operation. The water pump component 50 draws hot water stored in the first water storage component 40 and / or the second water storage component 70 to the heating component 60 for heating into boiling water, and then directly delivers it to the outlet component 10 for output. It can be understood that at this time, the water does not pass through the heat exchange component 30 and the cooling component 80 is not running. The water flow direction can be controlled by setting switches in the water path between the various components, which will not be described in detail here.

[0118] In the boiled water mode, the water pump assembly 50 and heating assembly 60 are also activated. The water pump assembly 50 draws hot water stored in the first water storage assembly 40 and / or the second water storage assembly 70 to the heating assembly 60 for heating into boiling water. This boiling water then passes through the second water path of the heat exchange assembly 30, exchanging heat with the ambient temperature water flowing through the first water path. This cools the water to the target temperature before it is output from the outlet assembly 10, achieving an instantaneous, high-flow-rate boiled water supply. The ambient temperature water in the first water path is heated to hot water and flows into the first water storage assembly 40. Similarly, the cooling assembly 80 is not activated at this time. The water flow direction is controlled by switches installed in the water paths between the various components, which will not be elaborated upon here.

[0119] In cold water mode, the control component activates the water pump assembly 50 and the cooling assembly 80. At this time, the heating assembly 60 is off, and the water flow does not pass through the heat exchange assembly 30. In one embodiment, the water pump assembly 50 draws water stored in the second water storage assembly 70 to the cooling assembly 80, directly cooling it to the target temperature before outputting it through the outlet assembly 10. In another embodiment, the water pump assembly 50 draws water stored in the second water storage assembly 70 to the cooling assembly 80 to lower its temperature, then returns it to the second water storage assembly 70. Through this cyclical cooling process, the target temperature cold water is ultimately stored and output directly when needed by the user. It is understood that in cold water mode, the water flow direction can also be controlled by setting switches or other methods in the water path between the components, which will not be elaborated upon here.

[0120] The above-mentioned solution allows the drinking water system to output not only boiled and cooked water, but also cold water according to user needs, thus taking into account users' needs for both hot and cold drinking water and having strong applicability.

[0121] In one embodiment, the drinking water system further includes a water replenishment branch 41, a second double-pass switch 12, and a water replenishment switch 42. The operation method further includes: when the water level of the first water storage component 40 and / or the second water storage component 70 is lower than a preset water level threshold, controlling the water replenishment switch 42 and the second double-pass switch 12 to start operation, so as to replenish water to the first water storage component 40 and / or the second water storage component 70.

[0122] Specifically, the first water storage component 40 and the second water storage component 70 have similar structures, and each can include a water storage tank, a temperature detector and a liquid level detector. The temperature detector can detect the water temperature inside the water tank, and the liquid level detector can monitor the liquid level inside the water tank.

[0123] The control component compares and analyzes the water level detected by the level detector with the preset water level threshold. If the water level of any water storage component is lower than the preset water level threshold, it will replenish the water.

[0124] It should be noted that, in one embodiment, during water replenishment, in order to prevent water from entering the heat exchange assembly 30 from the flow regulating component 71 under pressure, the flow regulating component 71 needs to be completely shut off to disconnect the water path.

[0125] The above solution can replenish water to the first water storage component 40 and / or the second water storage component 70 when the water level is low, ensuring the water storage capacity of the first water storage component 40 and / or the second water storage component 70.

[0126] In one embodiment, the drinking water system further includes a return water pipe 43, and the operation method further includes: in standby mode, acquiring a first water temperature of the first water storage component 40 and / or a second water temperature of the second water storage component 70; if the first water temperature is lower than a preset heat preservation threshold, controlling the water pump component 50 and the heating component 60 to start operation, so as to circulate and heat the hot water stored in the first water storage component 40 to the preset heat preservation threshold for storage; if the second water temperature is lower than the preset heat preservation threshold, controlling the water pump component 50 and the heating component 60 to start operation, so as to circulate and heat the hot water stored in the second water storage component 70 to the preset heat preservation threshold for storage.

[0127] Specifically, in this embodiment, both the first water storage component 40 and the second water storage component 70 can be used to store hot water, and the water temperature is monitored in real time by an internal water temperature detector. When the water temperature of either water storage component falls below a preset heat preservation threshold, a circulating heating mode is entered to heat the water to the preset heat preservation threshold (such as 70°C) for storage.

[0128] In the above solution, when the water temperature of the first water storage component 40 and / or the second water storage component 70 is detected to be too low in standby mode, the hot water stored in the first water storage component 40 and / or the second water storage component 70 can be circulated and heated to maintain the hot water temperature of the first water storage component 40 and / or the second water storage component 70, ensuring that when there is a demand for hot water, the hot water can be heated to boiling water in a shorter time.

[0129] In one embodiment, the operation method further includes: when a preset cooling shutdown condition is met, controlling the water pump assembly 50 and the heating assembly 60 to start operation, so as to circulate and heat the cold water stored in the second water storage assembly 70 to a preset heat preservation threshold for storage.

[0130] Specifically, in real-world scenarios, considering that the demand for cold water (usually below 15℃) is not as high as the demand for hot water, the drinking water system will not automatically activate the cooling function. The cooling function must be manually activated by the user through the control panel or terminal. Furthermore, to reduce overall power consumption and save energy, the control component uses the second temperature detector inside the second water storage component 70 to determine the time it takes for the water temperature to return to room temperature after cooling, thus determining whether the preset cooling shutdown conditions are met.

[0131] Specifically, after a user draws cold water and the cooling function completes its cooling and insulation process normally, if the user does not operate the system or draw cold water for an extended period, allowing the cold water temperature to naturally rise to room temperature (or other set temperature), the control component starts timing. If, even after the preset time (e.g., 2 hours), the user still does not operate the second water storage component 70, it can be determined that the user has no further need for cold water, and the system automatically shuts off the cooling function. If the cooling function is shut off and the user does not perform any other operations, and the entire unit is idle, the unit can activate the heating circulation function to heat the water in the second water storage component 70 to the preset insulation threshold for storage. Correspondingly, the unit effectively has two hot water storage tanks, allowing the user to draw more hot water when they have a larger flow of hot water needed next time.

[0132] It is understood that in another embodiment, the control component may determine that the preset cooling shutdown conditions are met when it receives a cooling shutdown command sent by the user. The specific selection can be made according to actual needs.

[0133] The above solution can automatically switch to the second water storage component 70 to store hot water when the cooling of the drinking water system is turned off. When there is a need for hot water later, hot water can be provided in the form of dual hot water tanks for heating, further increasing the amount of hot water available.

[0134] This application also provides a water dispenser, including the above-described water dispensing system, and a control component for performing the steps of the above-described operating method.

[0135] Specifically, the water supply system and its operation method are as shown in the above embodiments and accompanying drawings, and will not be repeated here. This water dispenser can be an under-sink water dispenser in a kitchen setting, or other types of water dispensers; there are no specific limitations. This water dispenser can not only output boiled and cooked water, but also output cold water according to user needs, thus catering to both hot and cold drinking water requirements and possessing strong applicability.

[0136] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0137] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
