Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a tabletop water purifier. Background Technology

[0002] With the development of the times, people have increasingly higher requirements for drinking water quality, and water purifiers have been widely recognized and purchased. Water purifiers can purify tap water or water in a water tank to provide users with high-quality clean water. Water purifiers on the market include built-in water purifiers, under-sink water purifiers, and countertop water purifiers. Countertop water purifiers have become a popular choice due to their ease of use.

[0003] Countertop water purifiers typically have a water tank to store raw water. Therefore, they can be used in locations without a tap water source, such as restaurants or bedrooms. Water purifiers that provide cold water have an internal cooling system. This cooling system needs to dissipate heat during the cooling process, so existing cold water purifiers usually have a fan to provide sufficient airflow for cooling.

[0004] Because air has a very low specific heat capacity, the air temperature around the cooling components rises rapidly under the same cooling power. A large volume of air needs to be pumped around the cooling components by a fan to ensure they maintain good heat dissipation. However, fans capable of pumping large volumes of air are noisy, resulting in a poor user experience. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, some embodiments of this utility model provide a tabletop water purifier, including: a water storage tank; a filter assembly having a raw water inlet, a purified water inlet, and a concentrated water inlet, the raw water inlet being connected to the water storage tank via a raw water pipeline, and a booster pump being installed on the raw water pipeline; and a cooling tank including a cold water chamber, a refrigeration component, and a water-cooling component, the inlet of the cold water chamber being connected to the purified water inlet via a water supply pipeline, and the outlet of the cold water chamber being connected to a main outlet, wherein: the cold end of the refrigeration component can exchange heat with the cold water chamber, and the hot end of the refrigeration component can exchange heat with the water-cooling component; and the inlet of the water-cooling component is connected to the concentrated water inlet via a concentrated water pipeline, and the outlet of the water-cooling component is connected to the water storage tank via a first water-cooling pipeline. Thus, the concentrated water generated during water purification can be used as cooling water for the refrigeration component to dissipate heat. Since the cooling process and water purification take the same amount of time, the noise is mainly generated by the booster pump. Water purification is a necessary part of the water purifier's operation, and the noise generated during this process is unavoidable. Therefore, the water purifier produces almost no additional noise during the cooling process, improving the user experience.

[0006] For example, the inlet of the water-cooling component is also connected to a water storage tank via a second water-cooling pipe, and a first circulation pump is installed on at least one of the first and second water-cooling pipes. To ensure that the cooling component can still dissipate heat through water cooling after the water purifier stops producing water, the first circulation pump can be used to return the raw water in the water storage tank to the water storage tank after absorbing heat through the water-cooling component. Optionally, during water purification, concentrated water can be used as cooling water for heat dissipation. Alternatively, during water purification, concentrated water can be used as cooling water for heat dissipation, while the first circulation pump pumps a portion of the raw water to increase the cooling water flow rate. When the water purifier stops producing water, the first circulation pump can pump the raw water as cooling water for cooling. Optionally, the first circulation pump can also use raw water to flush the water-cooling component, preventing scale buildup in the pipes of the water-cooling component. This allows for a large supply of cold water to the user, improving the user experience.

[0007] For example, a first check valve is installed on the concentrate pipeline. The first check valve can prevent the raw water pumped by the first circulation pump from flowing back from the concentrate pipeline to the concentrate outlet of the filter assembly under pressure when the booster pump stops working, thus avoiding affecting the performance and lifespan of the filter assembly.

[0008] For example, a first circulation pump is installed on a first water-cooling pipeline, and a second check valve is installed on a second water-cooling pipeline. When the first circulation pump is not working, concentrated water can also return from the water-cooling components and the first circulation pump to the water storage tank under the action of the second check valve, without flowing directly back to the water storage tank through the second water-cooling pipeline and bypassing the water-cooling components.

[0009] For example, the countertop water purifier further includes: an auxiliary water-cooling component, the hot ends of which are capable of heat exchange with the cooling component; a third water-cooling pipe connected between the water storage tank and the inlet of the auxiliary water-cooling component; and a fourth water-cooling pipe connected between the outlet of the auxiliary water-cooling component and the water storage tank, wherein at least one of the third and fourth water-cooling pipes is equipped with a second circulation pump. Thus, the concentrated water produced during water purification or the raw water used for rinsing can be cooled by the water-cooling component, and the raw water pumped by the second circulation pump can be cooled by the auxiliary water-cooling component, with their flow rates not interfering with each other, resulting in better water cooling performance.

[0010] For example, a wastewater ratio solenoid valve is installed on the concentrate pipeline. The rapidly discharged raw water also prevents the filter assembly from producing purified water; all raw water can return to the storage tank via the concentrate pipeline and water-cooling assembly under the action of the booster pump. In short, the water purifier can also flush the filter assembly via the wastewater ratio solenoid valve, and during the flushing process, the cooling assembly is cooled by water.

[0011] For example, the countertop water purifier also includes a purified water tank, which is connected in series on the water supply line. The purified water tank can store a large amount of purified water produced by the filtration assembly. When the user needs cold water, the purified water tank can replenish the cold water chamber with room temperature purified water. This avoids the need to start the booster pump to produce water every time the user needs cold water, reducing the number of times the booster pump starts and stops, extending the lifespan of the filtration assembly, and reducing the noise of the water purifier. In some embodiments, the filtration assembly has a low-flow-rate filter element (daily water production less than 400 gallons). In this case, the purified water tank can also temporarily store the produced purified water when the user is not using water, thus allowing a large flow of cold or room temperature water to be provided to the user. Furthermore, water cooling causes the water temperature in the storage tank to rise; the purified water tank ensures that the purified water replenished to the cold tank or the room temperature water provided to the user is at a relatively low temperature.

[0012] For example, a cold water pump is installed on the water supply line. The cold water pump is located downstream of the purified water tank. The cold water pump can pump cold water to a height above the cold water chamber or above the liquid level in the purified water tank, effectively increasing the water flow rate and improving the user experience. Furthermore, the cold tank is only connected to the outside world through the cold water pipeline. When the user needs cold water, the cold water pump can draw room-temperature purified water from the purified water tank to replenish the cold tank, forcing the cold water inside the cold tank to the main outlet. Therefore, the cold tank does not have a vent for balancing air pressure, resulting in a simpler structure. By not connecting to the atmosphere through a vent, foreign objects, dust, and bacteria can be prevented from entering the cold tank, making it less prone to bacterial growth and allowing for simple maintenance such as evacuation.

[0013] For example, the water tank is also connected to the main water outlet via an outlet pipe, on which a water pump is installed. The outlet pipe allows room-temperature purified water from the water tank to be supplied to the user. Similar to a cold water pump, the outlet pump also allows for unrestricted main water outlet height and provides a larger flow rate of room-temperature water.

[0014] For example, a heating element is connected in series on the water outlet pipe. Thus, the purified water at room temperature in the water tank can be heated by the heating element and provided to the user.

[0026] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0027] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0028] This utility model provides a countertop water purifier. The countertop water purifier according to an embodiment of this utility model will be described in detail below with reference to the accompanying drawings. Figure 1 As shown, the countertop water purifier has a main water outlet 10, which can provide at least filtered room temperature water and cooled water. As mentioned above, the countertop water purifier includes a water storage tank 200, which can store raw water. Raw water includes, but is not limited to, tap water and bottled water. Optionally, the user can remove the water storage tank 200 from the main body of the countertop water purifier, add raw water, and then reinstall it on the main body. The countertop water purifier may also include a filter assembly 100, which has a raw water outlet 101, a purified water outlet 102, and a concentrate outlet 103. The filter assembly 100 may include a reverse osmosis filter, a nanofiltration filter, or a combination of both. Both types produce a certain proportion of concentrate during the filtration process, which is discharged from the concentrate outlet 103. Both types of filter assemblies 100 have good filtration performance and can provide users with high-quality purified water. Optionally, in addition to reverse osmosis or nanofiltration filters, ultrafiltration filters, activated carbon filters, etc., can also be incorporated into the filter elements of the filtration assembly 100. Optionally, the filtration assembly 100 may include a pre-filter and a central filter. The pre-filter may include one of activated carbon, polypropylene fiber (PP) cotton, porous ceramic filters, etc., or any two or more of these composite filters. It can be placed before the central filter to perform pre-filtration on the water entering the central filter, thereby extending the service life of the central filter.

[0029] The raw water inlet 101 is connected to the water storage tank 200 via the raw water pipeline 300, and a booster pump 310 can be installed on the raw water pipeline 300. The booster pump 310 can pressurize the raw water in the water storage tank 200, which has almost no pressure, and pump it to the filter assembly 100, so that it has sufficient pressure to pass through the filter assembly 100 to generate clean water.

[0030] The countertop water purifier may also include a cold tank 400, which may include a cold water chamber (not shown) disposed therein. Optionally, the cold water chamber may have a shape substantially the same as the main body of the cold tank 400, being cubic in shape. Optionally, the cold tank 400 may have tortuous pipes formed inside, with the cold water chamber having an inner cavity formed by the pipes, thereby increasing the inner surface area of ​​the cold water chamber. The cold tank 400 may also include a refrigeration component, which may include a compressor-type refrigeration component, a semiconductor refrigeration component, or other existing or future refrigeration components. Regardless of the type of refrigeration component, heat is generated during the refrigeration process, causing one part of the refrigeration component to form a hot end and the other part to form a cold end. The cold end of the refrigeration component can exchange heat with the cold water chamber, thereby cooling the water in the cold water chamber. The inlet of the cold water chamber is connected to the purified water outlet 102 via a water supply pipe 700, and the outlet of the cold water chamber is connected to the main outlet 10. Thus, the water purifier can provide users with cold water below room temperature. Optionally, the main water outlet 10 can be connected to a faucet or a water spout. Optionally, the main water outlet 10 can have multiple separate openings, so that water that has undergone different treatments, such as chilled water or heated water, can be provided to the user through different openings without interference.

[0031] For any existing type of refrigeration component, the refrigeration efficiency decreases when the temperature difference between its hot and cold ends is too large. Taking semiconductor refrigeration as an example, when the temperature difference between its hot and cold ends reaches more than 50 degrees Celsius, its refrigeration effect decreases significantly, causing the water temperature in the cooling tank 400 to hardly decrease any further, making it difficult for the water purifier to provide the required temperature of cold water. Therefore, the hot end of the refrigeration component needs to be cooled. The hot end of the refrigeration component can exchange heat with the water-cooling component 410, which can transfer the heat from the hot end to the cooling water. Since water has a much higher specific heat capacity than air, the temperature rise of the same volume of water is much less than that of the same volume of air during the process of water passing through the water-cooling component 410. In some embodiments, the refrigeration component includes a compressor and a refrigerant circulation pipeline. In this case, the water-cooling component 410 can be constructed as nested pipelines, with one of the refrigerant and cooling water flowing in the inner tube of the water-cooling component 410, and the other flowing between the outer wall of the inner tube and the outer tube. Optionally, the water-cooling component 410 may include heat sinks and water pipes made of thermally conductive material embedded in the heat sinks. Optionally, the water-cooling assembly 410 may include a water cooling head. For a thermoelectric cooler, since it does not have a piping structure, the water-cooling assembly 410 may be a planar assembly such as the water cooling head described above.

[0032] When the filter element 100 produces water, a certain proportion of concentrated water is generated. This concentrated water can be used as cooling water to provide heat dissipation for the cooling components. The inlet of the water-cooling component 410 can be connected to the concentrated water outlet 103 via the concentrated water pipe 500, and the outlet of the water-cooling component 410 can be connected to the water storage tank 200 via the first water-cooling pipe 420. Optionally, the concentrated water pipe 500 or the first water-cooling pipe 420 can also be constructed as part of the water-cooling component 410, for example, at least a portion of the concentrated water pipe 500 or the first water-cooling pipe 420 can be made of thermally conductive material and in contact with the hot end. Thus, only a very small flow rate of cooling water is needed to achieve the same cooling effect as a larger flow rate of air. Experiments show that, within a calibrated time, when the water is cooled to the preset temperature, the cooling power is 60W, the temperature difference between the cold water and the air is 10 degrees Celsius, and the required air flow rate is 279 L / min. With the same cooling power of 60W and a temperature difference of 5 degrees between cold water and cooling water, the required water flow rate is only 170mL / min.

[0033] Therefore, the concentrated water produced during water purification can be used as cooling water for the refrigeration components. Since the refrigeration process coincides with the water purification process, the noise is mainly generated by the operation of the booster pump 310. Water purification is a necessary process for the water purifier, and the noise generated during this process is unavoidable. This way, the water purifier produces almost no additional noise during the refrigeration process, improving the user experience.

[0034] like Figure 2 As shown, exemplarily, the countertop water purifier also includes a purified water tank 710, which is connected in series with the water supply pipe 700. The purified water tank 710 can store a large amount of purified water produced by the filter assembly 100. When the user needs cold water, the purified water tank 710 can replenish the cold water chamber with room temperature purified water. This avoids the need to start the booster pump 310 to produce water every time the user needs cold water, reducing the number of start-stop cycles of the booster pump 310, extending the service life of the filter assembly 100, and reducing the noise of the water purifier. In some embodiments, the filter assembly 100 has a low-flow-rate filter element (daily water production less than 400 gallons). In this case, the purified water tank 710 can also temporarily store the produced purified water when the user is not using water, thereby allowing a large flow of cold or room temperature water to be provided to the user. Furthermore, water cooling causes the water temperature in the storage tank 200 to rise. Setting up a clean water tank 710 can ensure that the clean water supplied to the cold tank 400 or the room temperature water provided to the user is at a relatively low temperature.

[0035] For example, a cold water pump 720 can also be installed on the water supply pipe 700. The cold water pump 720 can be located downstream of the purified water tank 710. The cold water pump 720 can pump cold water to a height higher than the cold water chamber or the liquid level in the purified water tank 710, which can effectively increase the water flow rate and improve the user experience. Furthermore, the cold tank 400 is only connected to the outside world through the cold water pipe. When the user takes cold water, the cold water pump 720 can draw room temperature purified water from the purified water tank 710 to replenish the cold tank 400, and squeeze the cold water in the cold tank 400 to the main outlet 10. Therefore, the cold tank 400 does not have a vent for balancing air pressure, and its structure is relatively simple. By not connecting to the atmosphere through a vent, foreign objects, dust, and bacteria can be prevented from entering the cold tank 400, making it difficult for bacteria to grow inside the cold tank 400, and simple maintenance can be performed by simply purging.

[0036] For example, the water tank 710 is also connected to the main water outlet 10 via a water outlet pipe 800, on which a water pump 810 is installed. The water outlet pipe 800 can supply the user with purified water at room temperature from the water tank 710. Similar to the cold water pump 720, the water pump 810 also allows the height of the main water outlet 10 to be unrestricted and provides a larger flow rate of room temperature water.

[0037] For example, a heating element 820 is connected in series on the water outlet pipe 800. The heating element 820 may include, but is not limited to, existing or future heating elements such as a thick-film heating element 820, a hot water tank, or an electromagnetic heater. Thus, room-temperature purified water in the water tank 710 can be heated by the heating element 820 and provided to the user. Optionally, the water outlet pump 810 can control the flow rate, thereby enabling the water purifier to provide the user with hot water at a relatively accurate temperature.

[0038] like Figure 3As shown, exemplarily, the inlet of the water-cooling component 410 is also connected to the water storage tank 200 via a second water-cooling pipe 430, and a first circulation pump 440 is provided on at least one of the first water-cooling pipe 420 and the second water-cooling pipe 430. As mentioned above, the water purifier can only cool during the water production process, which results in a relatively short cooling time. This may be insufficient to meet user needs when users frequently use cold water. To ensure that the cooling component can still dissipate heat through water cooling after the water purifier stops producing water, the first circulation pump 440 can be used to return the raw water in the water storage tank 200 to the water storage tank 200 after absorbing heat through the water-cooling component 410. Optionally, during water production, concentrated water can be used as cooling water for heat dissipation. Optionally, during water production, concentrated water can be used as cooling water for heat dissipation, while the first circulation pump 440 pumps a portion of the raw water to increase the flow rate of the cooling water. When the water purifier stops producing water, the first circulation pump 440 can pump the raw water as cooling water for cooling. Optionally, the first circulation pump 440 can also use raw water to flush the water-cooling assembly 410, preventing scale buildup in the pipes of the water-cooling assembly 410. This allows for a larger supply of cold water to the user, improving the user experience.

[0039] like Figure 4 As shown, for example, a first check valve 510 may also be provided on the concentrate pipeline 500. The first check valve 510 can prevent the raw water pumped by the first circulation pump 440 from flowing back from the concentrate pipeline 500 to the concentrate port 103 of the filter assembly 100 under pressure when the booster pump 310 stops working, thus avoiding affecting the performance and lifespan of the filter assembly 100.

[0040] exist Figure 3 In the illustrated embodiment, the first circulation pump 440 is mounted on the second water-cooling pipeline 430. The water pressure generated by the first circulation pump 440 may affect the operation of the filter assembly 100, or the first circulation pump 440 may be affected by the concentrated water pressure. Figure 5 In the illustrated embodiment, the first circulation pump 440 can be installed on the first water-cooling pipeline 420, allowing the first circulation pump 440 to draw in both raw water and concentrated water and pump them back to the water storage tank 200. Optionally, a second check valve 431 is installed on the second water-cooling pipeline 430. When the first circulation pump 440 is not operating, the concentrated water can also return to the water storage tank 200 from the water-cooling assembly 410 and the first circulation pump 440 under the action of the second check valve 431, without passing through the second water-cooling pipeline 430 and flowing directly back to the water storage tank 200 without passing through the water-cooling assembly 410.

[0041] For example, the countertop water purifier may further include an additional water-cooling component 600, the hot ends of which are capable of heat exchange with the cooling component. The countertop water purifier may also include a third water-cooling pipe 460 and a fourth water-cooling pipe 470, the third water-cooling pipe 460 being connected between the water storage tank 200 and the inlet of the additional water-cooling component 600, and the fourth water-cooling pipe 470 being connected between the outlet of the additional water-cooling component 600 and the water storage tank 200. A second circulation pump 450 is provided on at least one of the third water-cooling pipe 460 and the fourth water-cooling pipe 470. Thus, the second circulation pump 450 can pump raw water between the water storage tank 200 and the additional water-cooling component 600.

[0042] In some embodiments employing semiconductor refrigeration, two or more semiconductor coolers may be installed on each cooling chamber 400. For example... Figure 6 As shown, each thermoelectric cooler can be matched with a water cooling head, where one or more water cooling heads can serve as water cooling components 410, and other water cooling heads can serve as auxiliary water cooling components 600. Water cooling components 410 and auxiliary water cooling components 600 are connected to the water storage tank 200 through different water paths, thereby avoiding excessively high water temperatures at the end of the water cooling head due to multiple water cooling heads connected in series, or insufficient water flow for each water cooling head due to multiple water cooling heads connected in parallel. Optionally, water cooling components 410 and auxiliary water cooling components 600 can be integrated, separated only by their water paths. Specifically, water cooling components 410 and auxiliary water cooling components 600 can include heat sinks and cooling pipes disposed on the heat sinks. Water cooling components 410 and auxiliary water cooling components 600 can share the same heat sink, and at least one of the two cooling pipes is connected to a third water cooling pipe 460 and a fourth water cooling pipe 470, and the other of the at least two cooling pipes is connected between the concentrate pipe 500 and the first water cooling pipe 420. Therefore, the concentrated water generated during water production or the raw water used for rinsing (mentioned below) can be cooled by the water cooling component 410, and the raw water pumped by the second circulation pump 450 can be cooled by the additional water cooling component 600. The flow rates of each component do not interfere with each other, and the water cooling effect is better.

[0043] Under the pressure of the booster pump 310, the raw water passes through the filter assembly 100, and the ratio of the purified water to the remaining concentrated water that does not pass through the filter assembly 100 is the wastewater ratio. The wastewater ratio can be limited by, for example, the structure of a wastewater ratio valve. For example, a wastewater ratio solenoid valve 520 is provided on the concentrated water line 500. The wastewater ratio solenoid valve 520 may include a valve core with a small orifice, which can function as a wastewater ratio valve. When the wastewater ratio solenoid valve 520 is closed, it maintains the pressure required for the filter assembly 100 to operate and allows a certain flow rate of concentrated water to pass through it. When the wastewater ratio solenoid valve 520 is open, raw water can quickly pass through it from a passage other than the wastewater ratio valve, thereby flushing the filter assembly 100. The rapidly discharged raw water also prevents the filter assembly 100 from producing purified water. All raw water can return to the water storage tank 200 via the concentrated water pipeline 500, the water-cooling assembly 410, and the first water-cooling pipeline 420 under the action of the booster pump 310. In short, the water purifier can also flush the filter assembly 100 through the wastewater ratio solenoid valve 520, and perform water-cooling heat dissipation on the cooling assembly during the flushing process. The water-cooling assembly 410 can also be flushed during the flushing process to prevent scale buildup on the water-cooling assembly 410.
