Description

Technical Field

[0001] This application relates to the field of water purifier technology, specifically to a water circuit structure for an integrated water purifier and heat purifier. Background Technology

[0002] As consumers pay more and more attention to healthy water and drinking water, and their requirements for water use are also getting higher and higher, integrated water purifiers and heaters are gaining more and more recognition and favor from consumers.

[0003] A water purifier and heater combo mainly consists of a filtration unit and a heating unit. The core component of the filtration unit is the filter cartridge. Different filter cartridges can perform different levels of filtration on the raw water. Most water purifiers and heater combos are equipped with RO filter cartridges or composite filter cartridges containing RO cartridges that can filter raw water into pure water. The core component of the heating unit is the instant heating element, which can heat water to boiling in a short time.

[0004] While RO filters generally offer good filtration and purification, their filtration speed is relatively slow, producing less pure water per unit time. When users need a large volume of water, integrated water purifiers and heaters often struggle to meet this demand quickly, resulting in longer waiting times and a poor user experience. RO filters typically consist of a central tube and a reverse osmosis membrane element surrounding it. When the integrated water purifier and heater is left to stand, water molecules, inorganic salts, and heavy metal ions exchange across the reverse osmosis membrane element through diffusion. This results in the TDS concentration on both sides of the membrane element gradually converging. Therefore, when the integrated water purifier and heater is restarted after a period of settling, the initial water flow may have a higher TDS, making the first few cups of water unsuitable for direct consumption and providing a poor user experience. Utility Model Content

[0005] This application provides a water circuit structure for an integrated water purifier and heater to improve or solve the technical problems of existing integrated water purifiers and heaters having low water supply per unit time and high TDS in the first few cups of water when restarted after being left to stand for a period of time.

[0006] The technical solution adopted in this application is as follows:

[0007] A water circuit structure for an integrated water purifier and heat pump includes a filtration unit and a pure water tank. The filtration unit has a raw water inlet and a pure water outlet. The pure water tank has a water replenishment inlet and a first ambient temperature water outlet. The pure water outlet is connected to the water replenishment inlet through a first water replenishment valve. The pure water outlet is connected to the ambient temperature water discharge port of the integrated water purifier and heat pump through a first water outlet valve. The first ambient temperature water outlet is connected to the ambient temperature water discharge port through a first water pump, so that the filtration unit and the pure water tank can supply water to the ambient temperature water discharge port simultaneously.

[0008] The water circuit structure of the integrated water purifier and heat pump provided in this application also includes the following additional technical features:

[0009] The water circuit structure includes a mixing pipe for discharging water to the ambient temperature water outlet, the pure water outlet is connected to the mixing pipe through a first pipe, the first water outlet valve is located on the fluid path of the first pipe, the first ambient temperature water outlet is connected to the mixing pipe through a second pipe, and the first water pump is located on the fluid path of the second pipe.

[0010] The water circuit structure also includes a heating and heat preservation unit, which includes a heat preservation device and a heating structure. The heating structure can heat the pure water filtered by the filtration unit and store it in the heat preservation device. The heat preservation device is provided with a heat preservation water outlet, which is connected to the hot water discharge port of the integrated water purifier and heat preservation machine through a second water pump.

[0011] The heat preservation device is provided with a hot water inlet, the heating structure is provided with an instantaneous heating element, and the heat preservation water outlet is connected to the inlet of the instantaneous heating element through the second water pump, so that the heat preservation device can supply water to the instantaneous heating element; the outlet of the instantaneous heating element is connected to the hot water outlet through the second outlet valve and to the hot water inlet through the third outlet valve, so that the instantaneous heating element can selectively supply water to the hot water outlet and the heat preservation device.

[0012] The pure water tank is provided with a second ambient temperature water outlet, which is connected to the water inlet of the instantaneous heating element through a third water pump, so that the pure water tank and the heat preservation device can supply water to the instantaneous heating element either by choice or together.

[0013] The heating structure is installed on the insulation device and is capable of heating the water inside the insulation device.

[0014] The insulation device is equipped with a room temperature water inlet, and the pure water outlet is connected to the room temperature water inlet through a second water supply valve.

[0015] The water circuit structure also includes a one-in-two-out solenoid valve. The first ambient temperature water outlet is connected to the inlet of the one-in-two-out solenoid valve through the first water pump. The two outlets of the one-in-two-out solenoid valve are respectively connected to the ambient temperature water outlet and the hot water outlet, so that the pure water tank and the heat preservation device can supply water to the hot water outlet either by choice or together.

[0016] The pure water tank is equipped with a first water level detection device, which can control the pure water tank to stop discharging water when a first target water level is detected; the heat preservation device is equipped with a second water level detection device, which can control the heat preservation device to stop discharging water when a second target water level is detected.

[0017] The first water level detection device is a float water level gauge, and the second water level detection device is an electrode water level gauge; the pure water tank is equipped with a UV sterilization lamp for internal water sterilization treatment.

[0018] Due to the adoption of the above technical solution, the technical effects achieved by this application include at least the following:

[0019] 1. The water circuit structure of the integrated water purifier and heater provided in this application allows the filtered water from the filtration unit to be replenished into a pure water tank for storage. The pure water outlet is connected to the ambient temperature water outlet of the integrated water purifier and heater via a first water outlet valve. The first ambient temperature water outlet is connected to the ambient temperature water outlet via a first water pump, enabling the filtration unit and the pure water tank to simultaneously supply water to the ambient temperature water outlet. Therefore, compared to traditional integrated water purifiers that can only supply ambient temperature water to the ambient temperature water outlet through the filtration unit, this solution supplies ambient temperature water to the ambient temperature water outlet through both the filtration unit and the pure water tank, significantly increasing the water supply per unit time and allowing users to obtain a large volume of ambient temperature water in a short period of time. Shorten waiting time; furthermore, during the resting process of the integrated water purifier and heater, the pure water stored in the pure water tank will not be affected by the osmosis of the reverse osmosis membrane, and the TDS will not increase. Therefore, when the integrated water purifier and heater restarts water dispensing, the filter unit and the pure water tank can be controlled to supply water to the room temperature water outlet together. The pure water discharged from the pure water tank and the pure water with a higher TDS value newly filtered by the filter unit can be mixed in the user's water container, thereby diluting the water molecules, inorganic salts, heavy metal ions and other substances in the pure water, ensuring that the pure water taken by the user is always in a state of low TDS value and can be directly drunk, ensuring the user's drinking water health and improving the user experience.

[0020] 2. As a preferred method, by setting up a mixing pipeline, during the process of controlling the filter unit and the pure water tank to supply water to the room temperature water outlet, the pure water discharged from the pure water tank and the pure water filtered by the filter unit can be fully mixed in the mixing pipeline in advance. This ensures that the pure water can be diluted to reduce TDS before entering the water receiving container. This can effectively prevent the high TDS pure water discharged from the filter unit from entering the water receiving container before the pure water discharged from the pure water tank, thus increasing the risk that the user only receives pure water with higher TDS.

[0021] 3. As a preferred method, the heating structure can heat the pure water filtered by the filtration unit and store it in the insulation device. The insulation device supplies water to the hot water outlet through a second water pump. Since the water in the insulation device itself has a high insulation temperature, when the user draws hot water, the warm water in the insulation device can be quickly heated to the temperature required by the user, thus quickly supplying hot water to the user and shortening the user's waiting time. Moreover, compared with the method of filtering pure water while heating room temperature pure water through the heating structure, the larger water storage capacity in the insulation device can increase the hot water supply per unit time, realizing a large flow of hot water supply in a short time.

[0027] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] In the embodiments of this application, a water circuit structure for an integrated water purifier and heat pump is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0032] like Figure 1 and Figure 2 As shown, the water circuit structure of the integrated water purifier and heat pump provided in this application includes a filtration unit and a pure water tank 12. The filtration unit is provided with a raw water inlet 10 and a pure water outlet 11. The pure water tank 12 is provided with a water replenishment inlet 121 and a first ambient temperature water outlet 122. The pure water outlet 11 is connected to the water replenishment inlet 121 through a first water replenishment valve 13. The pure water outlet 11 is connected to the ambient temperature water discharge port 15 of the integrated water purifier and heat pump through a first water outlet valve 14. The first ambient temperature water outlet 122 is connected to the ambient temperature water discharge port 15 through a first water pump 16, so that the filtration unit and the pure water tank 12 can supply water to the ambient temperature water discharge port 15 simultaneously.

[0033] It should be noted that this application does not limit the structure of the filtering unit. In a preferred embodiment, such as... Figure 1As shown, the filtration unit can include a first filter element 17 and a second filter element 18 connected in series after the first filter element 17. The inlet port of the first filter element 17 constitutes the raw water inlet 10, and the outlet port of the second filter element 18 constitutes the pure water outlet 11. The raw water is first filtered by the first filter element 17, and the pure water output from the first filter element 17 is then filtered again by the second filter element 18 to improve the filtration effect. In a specific embodiment, the first filter element 17 can be a composite filter element including an RO filter element, and the second filter element 18 can be a carbon filter element. In another preferred embodiment, such as... Figure 2 As shown, the filtration unit can include a third filter element 19, and the inlet and outlet ports of the third filter element 19 constitute the raw water inlet 10 and the pure water outlet 11, respectively. Preferably, the third filter element 19 can be a composite filter element that includes an RO filter element.

[0034] Specifically, in Figure 1 In the illustrated embodiment, the water circuit structure further includes an inlet valve 20, a booster pump 21, a wastewater valve 22, and a first check valve 231. The inlet valve 20 controls the inflow of water into the water circuit structure. The booster pump 21 pressurizes the incoming water before it enters the first filter element 17. The wastewater valve 22 controls the first filter element 17 to discharge wastewater. When room temperature water is needed, the inlet valve 20 is opened, and the booster pump 21 starts working. Tap water passes sequentially through the inlet valve 20, the booster pump 21, the first filter element 17, and the second filter element 18 to be filtered into room temperature pure water. The room temperature pure water can flow directly through the first outlet valve 14 to the room temperature water outlet 15, or it can be transported to the pure water tank 12 for storage through the first water supply valve 13. The pure water in the pure water tank 12 can be pumped to the room temperature water outlet 15 by the first water pump 16. The first check valve 231 is located between the first filter element 17 and the second filter element 18, allowing unidirectional flow from the first filter element 17 to the second filter element 18. Figure 2 In the embodiment shown, the water circuit structure may include an inlet valve 20, a booster pump 21, a wastewater valve 22, and a second check valve 232. The second check valve 232 is located on the return path from the pure water outlet 11 of the third filter element 19 to the booster pump 21.

[0035] The water circuit structure of this integrated water purifier and heater allows the filtered water from the filtration unit to be stored in the pure water tank 12. The pure water outlet 11 is connected to the ambient temperature water outlet 15 of the integrated water purifier and heater via the first outlet valve 14. The first ambient temperature water outlet 122 is connected to the ambient temperature water outlet 15 via the first water pump 16, enabling the filtration unit and the pure water tank 12 to simultaneously supply water to the ambient temperature water outlet 15. Therefore, compared to traditional integrated water purifiers that can only supply ambient temperature water to the ambient temperature water outlet through the filtration unit, this solution allows the filtration unit and the pure water tank 12 to supply ambient temperature water to the ambient temperature water outlet 15 together, significantly increasing the water supply per unit time and allowing users to draw large amounts of water in a short time. The system provides a sufficient supply of room temperature water, reducing waiting time. Furthermore, during the cooling and heating cycle, the pure water stored in the pure water tank 12 is not affected by the reverse osmosis membrane, and the TDS (Total Dissolved Solids) level does not rise. Therefore, when the system restarts, the filtration unit and the pure water tank 12 can supply water to the room temperature water outlet 15 together. The pure water discharged from the pure water tank 12 mixes with the newly filtered pure water (higher TDS) in the user's water container, diluting water molecules, inorganic salts, heavy metal ions, and other substances in the pure water. This ensures that the pure water used by the user remains at a low TDS level, making it safe for direct consumption and guaranteeing the user's drinking water health, thus improving the user experience.

[0036] As a preferred embodiment of this application, such as Figure 1 As shown, the water circuit structure includes a mixing pipe 24 for discharging water to the ambient temperature water outlet 15, a pure water outlet 11 connected to the mixing pipe 24 via a first pipe 25, a first water outlet valve 14 located on the fluid path of the first pipe 25, a first ambient temperature water outlet 122 connected to the mixing pipe 24 via a second pipe 26, and a first water pump 16 located on the fluid path of the second pipe 26. Those skilled in the art will understand that, during the design of the integrated water purifier and heating unit, there are various uncertainties, such as the pipeline from the pure water outlet 11 to the ambient temperature water outlet 15 being shorter than the pipeline from the pure water tank 12 to the ambient temperature water outlet 15. This could lead to the possibility that the pure water discharged from the filtration unit enters the receiving container before the pure water discharged from the pure water tank 12. If this portion of water fills the receiving container, it is easy for the user to only receive pure water with a higher TDS. Therefore, this solution sets up a mixing pipe 24. During the process of controlling the filtration unit and the pure water tank 12 to supply water to the ambient temperature water outlet 15 together, the pure water discharged from the pure water tank 12 and the pure water filtered by the filtration unit can be fully mixed in the mixing pipe 24 beforehand. This ensures that the pure water can be diluted and its TDS reduced before entering the receiving container, effectively reducing the risk that the user only receives pure water with a higher TDS.

[0037] As a preferred embodiment of this application, such as Figure 1As shown, the water circuit structure also includes a heating and insulation unit, which includes an insulation device 27 and a heating structure 28. The heating structure 28 can heat and store the pure water filtered by the filtration unit within the insulation device 27. The insulation device 27 is provided with an insulation water outlet 271, which is connected to the hot water discharge port 30 of the integrated water purifier and heat pump via a second water pump 29. Those skilled in the art will understand that, due to the insulation effect of the insulation device 27, the water within the insulation device 27 itself has a high insulation temperature. This allows the warm water in the insulation device 27 to be quickly heated to the user's desired temperature when the user draws hot water, thus enabling rapid supply of hot water and shortening the user's waiting time. Moreover, compared to the filtration unit filtering pure water while simultaneously heating room-temperature pure water via the heating structure 28, the larger water storage capacity within the insulation device 27 increases the hot water supply per unit time, achieving a large flow of hot water supply in a short period.

[0038] This application does not limit the specific form of the heating structure, and any one of the following embodiments one and two can be used:

[0039] Example 1: As Figure 1 As shown, the heat preservation device 27 is provided with a hot water inlet 272, the heating structure 28 is provided with an instantaneous heating element 281, and the heat preservation water outlet 271 is connected to the inlet of the instantaneous heating element 281 through the second water pump 29, so that the heat preservation device 27 can supply water to the instantaneous heating element 281; the outlet of the instantaneous heating element 281 is connected to the hot water outlet 30 through the second outlet valve 31 and to the hot water inlet 272 through the third outlet valve 32, so that the instantaneous heating element 281 can selectively supply water to the hot water outlet 30 and the heat preservation device 27. In this embodiment, the heating structure 28 is configured as an instantaneous heating element 281. The heat-preserving water in the heat preservation device 27 can be transported to the instantaneous heating element 281 through the second water pump 29. After the instantaneous heating element 281 reheats the water to a boil, it can be transported back to the heat preservation device 27 through the third water outlet valve 32 for heat preservation. Therefore, the heat preservation device 27 and the instantaneous heating element 281 can form a circulating heating loop, keeping the water in the heat preservation device 27 at a temperature above the set temperature. In specific implementation, a temperature detection device for detecting water temperature can be installed on the heat preservation device 27. Once the temperature detection device detects that the heat-preserving water is below the set temperature, the heat preservation device 27 and the instantaneous heating element 281 can be activated for circulating heating, thereby raising the water temperature in the heat preservation device 27 to above the set temperature. Specifically, a flow meter 33 can be installed on the water path upstream of the instantaneous heating element 281 for flow monitoring, and NTCs can be installed at the inlet and outlet of the instantaneous heating element 281 for temperature detection.

[0040] Furthermore, such as Figure 1As shown, the pure water tank 12 is equipped with a second ambient temperature water outlet 123. The second ambient temperature water outlet 123 is connected to the inlet of the instant heating element 281 through a third water pump 34, so that the pure water tank 12 and the heat preservation device 27 can supply water to the instant heating element 281 either individually or together, so that the integrated water purifier and heat sink can quickly produce water at different temperatures. For example, the heat preservation temperature of the heat preservation device 27 can be set to 90℃. When the user selects hot water above 90℃, the integrated water purifier and heat sink can control the second water pump 29 to draw water from the heat preservation device 27, and then quickly reheat it through the instant heating element 281 to reach the target temperature. When the user selects hot water between 85℃ and 90℃, since the heat preservation device 27 is at 90℃, hot water in this temperature range can be directly discharged through the second water pump 29, the instant heating element 281 (not working), and the third outlet valve 32. There is a temperature drop, so the instant heating element 281 does not need to operate at this time. When the user selects hot water at 55℃-84℃, room temperature water is drawn from the pure water tank 12 by the third water pump 34 and mixed with hot water drawn from the insulation device 27 by the second water pump 29. The temperature of the mixed water is then detected by the NTC at the inlet of the instant heating element 281, and the instant heating element 281 compensates for the temperature to the target temperature. When the user selects hot water at 45℃-54℃, room temperature water is drawn from the pure water tank 12 by the third water pump 34 and heated to the target temperature by the instant heating element 281. When the insulation device 27 is in an empty cavity state, water can be drawn from the pure water tank 12 by the third water pump 34, heated by the instant heating element 281, and then added to the insulation device 27.

[0041] Example 2: Figure 2 As shown, the heating structure 28 is installed on the heat preservation device 27 and can heat the water inside the heat preservation device 27. Unlike the solution in Embodiment 1 above, this embodiment directly installs the heating structure 28 on the heat preservation device 27, thus directly heating the water inside the heat preservation device 27. It can heat room-temperature water added to the heat preservation device 27, and can also reheat the water already in the heat preservation device 27. This solution simplifies the water circuit structure. Specifically, the heating structure 28 can be a heating wire, an electromagnetic heating plate, a heating tube, etc.

[0042] Preferably, such as Figure 2 As shown, the heat preservation device 27 is provided with a room temperature water inlet 273, and the pure water outlet 11 is connected to the room temperature water inlet 273 through the second water supply valve 35, so that the room temperature pure water filtered by the filter unit can be replenished into the heat preservation device 27 through the second water supply valve 35, and then the room temperature pure water is heated to the set temperature through the heating structure 28.

[0043] Preferably, such as Figure 2As shown, the water circuit structure also includes a one-in-two-out solenoid valve 36. The first ambient temperature water outlet 122 is connected to the inlet of the one-in-two-out solenoid valve 36 through the first water pump 16. The two outlets of the one-in-two-out solenoid valve 36 are respectively connected to the ambient temperature water outlet 15 and the hot water outlet 30, so that the pure water tank 12 and the heat preservation device 27 can selectively or jointly supply water to the hot water outlet 30. In this scheme, the water in the pure water tank 12 can be discharged in two ways through the one-in-two-out solenoid valve 36. One way is directly delivered to the ambient temperature water outlet 15, and the other way is delivered to the hot water outlet 30. The hot water outlet 30 is used to discharge hot water. Therefore, the way the pure water tank 12 discharges water to the hot water outlet 30 is usually activated together with the heat preservation device 27, so that the ambient temperature water in the pure water tank 12 and the hot water in the heat preservation device 27 are mixed before being discharged. In practice, the insulation temperature of the insulation device 27 can still be set to 90℃. When the user selects hot water above 90℃, the heating structure 28 can directly heat the water to the target temperature and discharge it to the hot water outlet 30. When the user selects hot water below 90℃, room temperature water is drawn from the pure water tank 12 by the first water pump 16. At this time, the end of the one-in-two-out solenoid valve 36 connected to the hot water outlet 30 is opened, and then mixed with the hot water drawn from the insulation device 27 by the second water pump 29. The water temperature after mixing can be detected by NTC to see if the water temperature is accurate. Then, the flow rate of the first water pump 16 or the second water pump 29 is adjusted until the target temperature is reached.

[0044] As a preferred embodiment, such as Figure 1 and Figure 2As shown, the pure water tank 12 is equipped with a first water level detection device 37. The first water level detection device 37 can control the pure water tank 12 to stop discharging water when it detects a first target water level. Specifically, the first water level detection device 37 can be used to detect the high water level and the low water level in the pure water tank 12, and set the low water level as the first target water level. In other words, when the first water level detection device 37 detects a low water level, it controls the pure water tank 12 to stop discharging water to prevent the first water pump 16 from running dry after the water in the pure water tank 12 is pumped out. During the process of the filter unit replenishing water to the pure water tank 12, when the first water level detection device 37 detects a high water level, it can send a message to the whole machine to stop replenishing water. The heat preservation device 27 is equipped with a second water level detection device 38. The second water level detection device 38 can control the heat preservation device 27 to stop discharging water when it detects a second target water level. Specifically, the second water level detection device 38 can be used to detect the high water level and low water level in the heat preservation device 27, and set the low water level as the second target water level. In other words, when the second water level detection device 38 detects a low water level, it controls the heat preservation device 27 to stop discharging water to prevent the second water pump 29 from running dry after the water in the heat preservation device 27 is pumped out, and also to reduce the risk of dry burning. When the heat preservation device 27 stops discharging water due to the low water level, when there is a demand for hot water, it can simply supply water to the instantaneous heating element 281 through the pure water tank 12 to heat it to the target temperature.

[0045] In a preferred embodiment of this application, the first water level detection device 37 is a float-type water level gauge, and the second water level detection device 38 is an electrode-type water level gauge; the pure water tank 12 is equipped with a UV sterilization lamp 39 for internal water sterilization. Those skilled in the art will understand that when the pure water stored in the pure water tank 12 is not used for a long time, bacteria can easily grow. Therefore, by setting up the UV sterilization lamp 39, ultraviolet light can be used for sterilization, improving the health of the water used.
