Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a water purification system. Background Technology

[0002] With the accelerating pace of life and diversified consumer demands, capsule beverages, with their rich flavors and convenient preparation, have seen a continuous rise in popularity in the domestic market, gradually becoming an important daily beverage choice for many consumers. During the consumption of capsule beverages, different types of capsule beverages and the drinking habits of different consumer groups place diverse demands on extraction methods. For example, for some capsule beverages, such as capsule coffee, high-pressure extraction with hot water is usually required to fully extract their flavor compounds; while some users, based on taste preferences or specific drinking scenarios, prefer cold water extraction for certain capsule beverages, i.e., cold brewing.

[0003] To meet the different extraction needs mentioned above, some water purifiers on the market have begun to integrate both high-pressure cold extraction and high-pressure hot extraction functions. Specifically, these water purifiers have two independent output water paths: one path is dedicated to cooling the water to output high-pressure cold water that meets the requirements of high-pressure cold extraction, thus achieving the cold extraction function; the other path is responsible for heating the water, outputting high-temperature and high-pressure hot water, thus achieving the high-pressure hot extraction function.

[0004] However, this design with two independent water output paths has significant limitations. The increased number of output paths leads to a more complex and cumbersome internal water circuit layout. Especially when the water purifier needs to function with other additional features, the number of corresponding auxiliary water paths often doubles to ensure coordinated operation, further exacerbating the complexity of the water system. This complexity not only increases the design difficulty, manufacturing costs, and maintenance complexity of the water purifier, but also necessitates optimization and improvement.

[0050] To address the issue of excessive water output paths in current water purifiers with both high-pressure hot extraction and high-pressure cold extraction functions, this application proposes a water purification system. Figure 1 This is a schematic diagram of the water purification system in the first embodiment of this utility model, as shown below. Figure 1 As shown, the water purification system includes: a first water storage unit 1, which has a container cavity for storing water; a water purification component 2, whose purified water outlet is connected to the container cavity to input the generated purified water into the container cavity; a cooling component 3, which is used to cool the purified water in the container cavity to generate low-temperature purified water; and an extraction component 4, which is used to extract the beverage capsules. The extraction component 4 is connected to the container cavity through a first water passage 6, on which a drive pump 62 and a heating component 63 for heating the flowing purified water are provided.

[0051] The water purification system in this application inputs the purified water generated by the water purification component 2 into the receiving cavity of the first water storage unit 1 for storage. Then, the purified water stored in the receiving cavity of the first water storage unit 1 is cooled by the cooling component 3 to generate low-temperature purified water. Thus, when the user needs the water purification system to output low-temperature purified water for high-pressure cold extraction of capsule beverages, the low-temperature purified water stored in the receiving cavity of the first water storage unit 1 can be directly output to the extraction component 4 through the first water path 6 using the drive pump 62, thereby completing the high-pressure cold extraction operation. When the user needs the water purification system to output high-pressure hot purified water for high-pressure hot extraction of capsule beverages, the heating component 63 can be turned on, and the low-temperature purified water stored in the receiving cavity of the first water storage unit 1 can be heated by the heating component 63 on the first water path 6 and output to the extraction component 4 under high pressure, thereby completing the high-pressure hot extraction operation. Through the above method, the water purification system in this application can achieve high-pressure hot extraction and high-pressure cold extraction functions using only a single first water path 6, effectively simplifying the water path and reducing the complexity of the water path in the water purification system.

[0052] like Figure 1 As shown, the water purification system includes: a first water storage unit 1, a water purification component 2, a cooling component 3, and an extraction component 4. The first water storage unit 1 has a water-storing cavity, serving as a container for storing the purified water generated by the water purification component 2. For example, the first water storage unit 1 can be a box or tank. Furthermore, the first water storage unit 1 has a heat preservation function to keep the purified water at low temperatures. The water purification component 2 is used to filter the raw water to generate purified water, which is then delivered to the first water storage unit 1. Alternatively, the water purification component 2 may include at least one filtration unit. The filtration unit is used to filter the water, and different types of filtration membranes can be selected according to specific needs. For example, the filtration unit may include at least one of the following: a reverse osmosis membrane filtration unit, a nanofiltration membrane filtration unit, an ultrafiltration membrane filtration unit, etc. Furthermore, the water purification component 2 may also include a pre-filtration unit and / or a post-filtration unit to treat the water for different functions. The specific types of pre-filtration and post-filtration units can be selected according to specific needs and will not be elaborated further here. Furthermore, the outlet of the water purification component 2 is connected to the receiving cavity through the second on / off valve 9 to realize the on / off connection between the outlet of the water purification component 2 and the receiving cavity.

[0053] The refrigeration component 3 is used to cool the purified water in the receiving cavity to generate low-temperature purified water. Different types of refrigeration components can be selected. In one feasible embodiment, the refrigeration component 3 may include a refrigeration system comprising a compressor 31, an evaporator 32, a condenser 33, and a throttling unit 34. The evaporator 32 can exchange heat with the purified water stored in the receiving cavity to generate low-temperature purified water. The evaporator 32 may be disposed in the receiving cavity of the first water storage unit 1, or it may be in direct or indirect contact with the wall surface of the first water storage unit 1, as long as it can transfer cooling energy to the wall surface of the first water storage unit 1, and then to the purified water in the receiving cavity of the first water storage unit 1. In other feasible embodiments, the refrigeration component 3 may also employ a semiconductor refrigeration element, which is not specifically limited in this application.

[0054] Extraction assembly 4 is used to extract beverage capsules to obtain the desired beverage. Extraction assembly 4 may include a loading structure for loading the beverage capsules. Extraction assembly 4 is connected to a receiving cavity via a first water passage 6. A drive pump 62 and a heating assembly 63 are provided on the first water passage 6 to heat the flowing purified water. The drive pump 62 drives the purified water in the receiving cavity of the first water storage unit 1 to be output through the first water passage 6 and to form the high pressure required for extraction. The heating assembly 63 is used to rapidly heat the purified water flowing through the first water passage 6 to form high-temperature purified water. For example, during high-pressure extraction of coffee, the high-temperature purified water can be heated to between 88 and 95 degrees Celsius, thereby ensuring the taste and quality of the coffee obtained through high-pressure extraction.

[0055] As is feasible, the heating component 63 may include at least one of the following: a heating boiler, a rapid heating module, etc.

[0056] When the drive pump 62 needs to provide high pressure to enable the water purification system to achieve high-pressure, high-temperature extraction, the drive pump 62 needs to be located upstream of the heating component 63. This ensures that the high-temperature purified water generated by the heating component 63 does not pass through the drive pump 62. The drive pump can be a vibratory pump, rotary pump, or diaphragm pump, etc. Conventional drive pumps 62 designed for water purification have a rated operating temperature range of less than or equal to 80 degrees Celsius. Once this range is exceeded, various damage mechanisms will work synergistically, causing a sharp decline in the performance and lifespan of the drive pump 62, or even instantaneous failure. For example, aging and failure of non-metallic components can render the drive pump 62 unusable. Non-metallic materials in the drive pump 62, such as seals (e.g., O-rings, rubber / resin components of mechanical seals), gaskets, etc., are extremely sensitive to temperature: high temperatures accelerate the oxidative degradation of rubber, causing the seals to harden, crack, or lose elasticity, resulting in ineffective sealing and leakage. If the dynamic / static rings of the mechanical seal use resin binders or polymer materials, high temperatures may also cause material softening and accelerated wear, significantly accelerating the seal failure rate. For example, the lubrication system of drive pump 62 may also fail. The bearings (rolling or sliding bearings) of drive pump 62 rely on grease or lubricating oil to reduce friction. High temperatures can cause: a decrease in the dropping point of grease (loss of viscosity), or a decrease in the viscosity of lubricating oil, preventing the formation of an effective oil film and accelerating bearing wear. Under prolonged high temperatures, grease may carbonize or coke, clogging lubrication channels and ultimately leading to bearing seizure and burnout. Furthermore, the motor of drive pump 62 may experience overheating and electrical faults. High-temperature water will transfer heat to the motor through the pump body. The insulation material of the motor windings (such as the enameled wire insulation layer) ages faster at high temperatures, reducing insulation performance and potentially causing short circuits or grounding faults. Deteriorating motor heat dissipation conditions can cause the operating temperature to exceed the rated value, leading to reduced motor efficiency, shortened lifespan, or even direct burnout.

[0057] The water purification system in this application inputs the purified water generated by the water purification component 2 into the receiving cavity of the first water storage unit 1 for storage, and then cools the purified water stored in the receiving cavity of the first water storage unit 1 through the cooling component 3 to generate low-temperature purified water.

[0058] The water purification system can have a first state in which the heating component 63 is off and the drive pump 62 is running to deliver low-temperature purified water from the containment chamber to the extraction component 4. When the user needs the water purification system to output low-temperature purified water for high-pressure cold extraction of capsule beverages, the water purification system enters the first state to complete the high-pressure cold extraction operation and meet the user's needs.

[0059] The water purification system has a second state in which the heating component 63 is turned on and the drive pump 62 is running. The pump heats the low-temperature purified water in the containment chamber through the heating component 63 to form high-pressure hot purified water, which is then delivered to the extraction component 4. When the user requires the water purification system to output high-pressure hot purified water for the hot extraction of capsule beverages, the water purification system enters the second state to complete the high-pressure hot extraction operation and meet the user's needs.

[0060] In this way, the water purification system of this application can realize high-pressure hot extraction and high-pressure cold extraction functions through only a single first water path 6, which effectively simplifies the water path and reduces the complexity of the water path in the water purification system.

[0061] Furthermore, when the drive pump 62 is located upstream of the heating assembly 63, in the second state, the low-temperature purified water in the containment chamber can be heated by the heating assembly 63 to form high-pressure, high-temperature purified water, and then the high-pressure, high-temperature purified water is transported to the extraction assembly 4. The high temperature here can be heated to a temperature higher than 80 degrees Celsius.

[0062] As a feasible option, Figure 2 This is a schematic diagram of the water purification system in the second embodiment of this utility model, as shown below. Figure 2 As shown, a sterilization component 61 can be installed on the first water path 6 to sterilize the purified water flowing through it. Since the first water storage unit 1 stores low-temperature purified water for extended periods, bacteria may grow. Therefore, sterilizing the purified water flowing through the first water path 6 using the sterilization component 61 can effectively ensure the quality of the output purified water. Especially when the water purification system is in its first state for high-pressure cold extraction, the low-temperature purified water has not undergone high-temperature sterilization by the heating component 63; the above method can effectively ensure the water quality for high-pressure cold extraction.

[0063] As a feasible option, such as Figure 2 As shown, the water purification system may include a return water path 5, one end of which is connected to the receiving cavity, and the other end of which is connected to the first water path 6 downstream of the heating component 63 and the drive pump 62. The return water path 5 can return purified water from the first water path 6 to the receiving cavity. Furthermore, the connection point between the other end of the return water path 5 and the first water path 6 can be close to the extraction component 4. In this way, a larger portion of the residual water in the first water path 6 can be returned to the receiving cavity, replacing that portion of the water in the first water path 6 with the same type of water required for the next output.

[0064] In order to control whether the water in the first water passage 6 enters the receiving cavity of the first water storage unit 1 through the return water passage 5, such as Figure 2As shown, a first on / off valve 51 can be installed on the return water path 5, or the other end of the return water path 5 can be connected to the first water path 6 through a switching valve so that the return water path 5 and the first water path 6 can be switched on and off.

[0065] The water purification system can have a third state in which the heating component 63 is off, the drive pump 62 is running, and the water path in the extraction component 4 is closed, so that the low-temperature purified water output by the drive pump 62 flows back to the receiving cavity through the return water path 5. Alternatively, in the third state, the first on / off valve 51 is in the connected state, or the return water path 5 is connected to the first water path 6 upstream of the switching valve.

[0066] To ensure that the water output from the water purification system in the next execution of the first state is primarily low-temperature purified water, thus improving the effect of high-pressure cold extraction, and not the residual room-temperature or hot purified water in the first water path 6, it is feasible to execute the third state before the first state, thereby replacing all the water in the first water path 6 with low-temperature purified water in advance. Furthermore, the third state can be executed after the second state. If, after the water purification system has executed the second state, the water in the first water path 6 is still hot purified water, the third state can replace this residual hot purified water.

[0067] The water purification system has a fourth state in which the heating component 63 is on, the drive pump 62 is running, and the water path in the extraction component 4 is closed. This allows the low-temperature purified water output by the drive pump 62 to be heated by the heating component 63 to form high-temperature purified water, which then flows back to the receiving cavity through the return water path 5. Alternatively, in the fourth state, the first on / off valve 51 is in the connected state, or the return water path 5 is connected to the first water path 6 upstream of the switching valve.

[0068] To ensure that the water output from the water purification system in the next execution of the second state is primarily hot purified water, thus improving the thermal extraction effect and avoiding the residual room-temperature or low-temperature purified water in the first water path 6, it is feasible to execute the fourth state before the second state, thereby replacing all the water in the first water path 6 with hot purified water in advance. Furthermore, the fourth state can be executed after the first state. After the water purification system has executed the first state, if the water in the first water path 6 is still low-temperature purified water, executing the fourth state will replace the residual low-temperature purified water in the first water path 6.

[0069] When the state of the water purification system is the same as the state of the previous execution, whether to execute the third or fourth state depends on the degree of temperature change of the residual low-temperature purified water or hot purified water in the first water circuit 6 under the ambient temperature. If the temperature change is large, the third or fourth state needs to be executed; if the temperature change is small, the third or fourth state does not need to be executed.

[0070] As a feasible option, Figure 3 This is a schematic diagram of the water purification system in the third embodiment of this utility model, as shown below. Figure 3 As shown, the water purification system may include an air pump 7, the outlet of which is connected to the first water channel 6 via a second water channel 8. The inlet of the air pump 7 can be extended through a pipeline to the extraction component 4 to connect with the atmosphere. When the user performs high-pressure hot extraction or high-pressure cold extraction using the extraction component 4, the air pump 7 can be used to drain the water from the water channel of the extraction component 4, thereby preventing dripping from the extraction component 4. Furthermore, the second water channel 8 can be connected to the first water channel 6 downstream of the heating component 63 and the drive pump 62, thus minimizing the amount of water discharged. As a feasible option, the water purification system has a fifth state in which the air pump 7 is on, the drive pump 62 is off, and the water channel in the extraction component 4 is open. The water purification system can drain the water from the water channel of the extraction component 4 by executing the fifth state.

[0071] As a feasible option, such as Figure 2 and Figure 3 As shown, a flow detection unit 64 is provided on the first water path 6. The flow detection unit 64 is used to detect the flow rate of the purified water flowing through the first water path 6, thereby controlling the water flow rate through the first water path 6 by driving the pump 62, such as the low temperature purified water flow rate during high pressure cold extraction and the hot purified water flow rate during high pressure hot extraction.

[0072] As a feasible option, Figure 4 This is a schematic diagram of the water purification system in the fourth embodiment of this utility model, as shown below. Figure 4As shown, the water purification system may include: a second water storage unit 10 capable of heating water and a water output mechanism 11. The second water storage unit 10 may be connected to the outlet of the water purification component 2, for example, the second water storage unit 10 is connected to the outlet of the water purification component 2 through a water supply valve 114. The water output mechanism 11 is used to output water to supply users to meet their water needs. This water may be ambient temperature purified water, hot purified water, and / or low temperature purified water. The second water storage unit 10 may be connected to the water output mechanism 11 through a hot water output channel 111. An output pump 12 and a hot water control valve 13 may be installed on the hot water output channel 111. The outlet of the water purification component 2 may be connected to the water output mechanism 11 through an ambient temperature output channel 112. An ambient temperature water control valve 15 may be installed on the ambient temperature output channel 112. The first water storage unit 1 may be connected to the water output mechanism 11 through a cold water output channel 113. The second water storage unit 10 may be connected to an exhaust pipe 101 that communicates with the atmosphere. For example, the exhaust pipe 101 may extend to the water output mechanism 11 and then communicate with the atmosphere.

[0073] When the water purification assembly 2 includes a pre-filter unit 21 and a post-filter unit 22, both can be independent filter elements or a composite filter element. When the filter unit 23 in the water purification assembly 2 needs to discharge wastewater during filtration, the wastewater outlet of the filter unit 23 is connected to a functional valve 24 with a wastewater ratio function. The water purification assembly 2 may include a booster pump 26 for pressurizing the filter unit 23 to improve the filtration rate of the filter unit 23. The water purification assembly 2 can be connected to a water source through an inlet valve 25.

[0074] Alternatively, the water purification system may include a circulating water path 16, through which the first water storage unit 1 can be connected to the inlet of or upstream of the booster pump 26. A third on / off valve 161 may be installed on the circulating water path 16. Through the cooperation of the circulating water path 16 and the booster pump 26, the water in the first water storage unit 1 can be made to flow, which facilitates the cooling component 3 in cooling the purified water in the receiving cavity and prevents the water in some areas of the first water storage unit 1 from freezing, thus affecting the cooling effect.

[0075] This application also proposes a control method for a water purification system, which may include the following steps:

[0076] The system obtains the extraction type selected by the user. The extraction type selected by the user can generally be divided into high-pressure cold extraction or high-pressure hot extraction. Furthermore, high-pressure hot extraction can select a specific type of hot extraction depending on the different capsule beverages, thus enabling the water purification system to output hot purified water at different temperatures.

[0077] When the extraction type is high-temperature purified water high-pressure extraction, the heating component 63 and the drive pump 62 are turned on so that the low-temperature purified water in the containment chamber is heated by the heating component 63 to generate high-temperature high-pressure purified water and then delivered to the extraction component 4.

[0078] When the extraction type is high-pressure extraction using low-temperature purified water, the control drive pump 62 is turned on so that the low-temperature purified water in the containment chamber is delivered to the extraction component 4.

[0079] As a feasible control method, it may include:

[0080] Before the extraction component 4 outputs low-temperature purified water, the control drive pump 62 is turned on, and the return water path 5 is connected to the first water path 6, so that the low-temperature purified water output by the drive pump 62 flows back to the containment cavity after passing through the return water path 5.

[0081] In this step, to connect the return water path 5 with the first water path 6, the first on-off valve 51 can be opened, or the switching valve can be switched to connect the return water path 5 with the first water path 6 upstream of the switching valve. Additionally, the heating component 63 is in the off state during this step. Through these methods, the water in the first water path 6 can be replaced with low-temperature purified water in advance, ensuring that the water output from the purification system at the beginning of the next execution of the first state is primarily low-temperature purified water, thereby improving the high-pressure cold extraction effect.

[0082] Furthermore, as an option, in this step, after the extraction component 4 outputs high-temperature purified water and before it outputs low-temperature purified water, the drive pump 62 can be turned on, and the return water path 5 can be connected to the first water path 6. This allows the low-temperature purified water output by the drive pump 62 to flow back into the receiving cavity after passing through the return water path 5. This replaces the residual hot purified water in the first water path 6, preventing it from affecting the high-pressure cold extraction effect.

[0083] As a feasible control method, it may include: before the extraction component 4 outputs high-temperature purified water, controlling the drive pump 62 and heating component 63 to start, and connecting the return water path 5 with the first water path 6, so that the low-temperature purified water output by the drive pump 62 is heated by the heating component 63 to form high-temperature purified water, and then flows back to the receiving cavity through the return water path 5. In this way, the water in the first water path 6 can be replaced with hot purified water in advance, so that when the water purification system executes the second state next time, the water output at the beginning is basically hot purified water, thereby improving the hot extraction effect.

[0084] Furthermore, as a feasible step, after the extraction component 4 outputs low-temperature purified water and before it outputs high-temperature purified water, the drive pump 62 and heating component 63 can be turned on, and the return water path 5 can be connected to the first water path 6. This allows the low-temperature purified water output by the drive pump 62 to be heated by the heating component 63 to form high-temperature purified water, which then flows back to the receiving cavity through the return water path 5. This process replaces the residual low-temperature purified water in the first water path 6, preventing it from affecting the high-pressure hot extraction effect.

[0085] As a feasible control method, it may include: after the extraction component 4 outputs low-temperature purified water or high-temperature purified water, the air pump 7 can be turned on, opening the water path in the extraction component 4, so that the air output by the air pump 7 discharges some of the purified water in the first water path 6 from the extraction component 4. In the above steps, the water in the water path of the extraction component 4 can be discharged, thereby preventing the extraction component 4 from dripping.
