[0002] Most water purifiers on the market today have an insulation or protective layer to keep the cold water in the tank warm. However, if the water stored in the tank is not used for a long time, it will develop an odor. Furthermore, when heating or cooling the water, the insulation or protective layer's molecular materials evaporate during the heat dissipation process of the heating module or compressor. This evaporation can then seep into the water through the tank or pipes, causing an unpleasant odor, affecting water quality and taste, and resulting in a poor user experience. Utility Model Content

[0040] Most water purifiers on the market today have an insulation or protective layer to keep the cold water in the tank warm. However, if the water stored in the tank is not used for a long time, it will develop an odor. Furthermore, when heating or cooling the water, the insulation or protective layer's molecular materials evaporate during the heat dissipation process of the heating module or compressor. This evaporation can then seep into the water through the tank or pipes, causing an unpleasant odor, affecting water quality and taste, and resulting in a poor user experience.

[0041] This utility model proposes a water circuit system for a water purifier, which can reflux and filter the water in the water tank again to solve the problems of odor and poor water quality in the water tank.

[0042] Please see Figure 1 In one embodiment of the present invention, the water system 100 of the water purifier includes a raw water tank 1, a filter module 2, a pure water tank 3, a heating module 4, and a cooling module 5, wherein the cooling module 5 includes a water storage tank 51.

[0043] Raw water tank 1 and pure water tank 3 are connected through a filter water path 11. Filter module 2 is set in filter water path 11 and located in the flow path between raw water tank 1 and pure water tank 3. Pure water tank 3 and water storage tank 51 are connected through a water replenishment path 12. Water storage tank 51 and filter module 2 are connected through a return water path 13. Water storage tank 51 is connected to water outlet 61 through a first water outlet path 14. Pure water tank 3 is connected to water outlet 61 through a second water outlet path.

[0044] The water supply path 12 is used to replenish the water in the pure water tank 3 to the water storage tank 51, and the return water path 13 is used to discharge the water in the water storage tank 51 to the filter module 2 for filtration.

[0045] Specifically, the water purifier has a housing 200. The housing 200 contains an installation space for the filter module 2, heating module 4, cooling module 5, water pump, piping, and other structures. A water outlet 61 is located on the housing 200 and is used to dispense water for drinking. Furthermore, the water outlet 61 is located on the front side of the housing 200, and there is at least one water outlet 61. In this embodiment, there is one water outlet 61, which can dispense hot water, cold water, and room temperature water, allowing water of three different temperatures to flow through a single outlet 61, reducing the number of outlets and simplifying the structural design. Of course, in other embodiments, the number of water outlets 61 can be multiple; there is no specific limitation on this.

[0046] Both the raw water tank 1 and the pure water tank 3 are installed on the housing 200 and are detachable from the housing 200 to facilitate the user's replenishment of raw water and to allow direct use of the pure water tank 3 when a large amount of pure water is needed. The raw water tank 1 and the pure water tank 3 are connected through the filtration water path 11. The raw water tank 1 is mainly used to hold raw water (i.e., tap water) and serves as the water source for the water system 100 of the water purifier. The pure water tank 3 is mainly used to store water filtered by the filtration module 2. The filtration module 2 is located in the flow path between the raw water tank 1 and the pure water tank 3 to filter the water flowing out of the raw water tank 1, and the filtered water flows into the pure water tank 3.

[0047] The filter module 2 is housed within the casing 200, with its inlet side connected to the outlet side of the raw water tank 1, and its outlet side connected to the pure water tank 3. Water in the raw water tank 1 can be filtered by the filter module 2 and then flow into the pure water tank 3 for storage. The filter module 2 includes at least one filter element, which can be an RO membrane reverse osmosis filter element 22, an activated carbon filter element, or a PP filter element.

[0048] Heating module 4 is located inside housing 200 and in the flow path between pure water tank 3 and water outlet 61. It should be noted that heating module 4 is an instant heating module used to heat the flowing water. When water in pure water tank 3 flows through heating module 4, the room temperature water in pure water tank 3 is heated to high temperature water and then flows out through the second water outlet for user consumption. A second water pump 50 is provided on the second water outlet to provide power for the water flow in the second water outlet. The second water pump 50 can be a diaphragm pump. The user can select the temperature of the high-temperature water according to their needs, for example, but not limited to, 45℃, 60℃, 75℃, 80℃, 85℃, 95℃, and 100℃.

[0049] The refrigeration module 5 is housed within the casing 200. The refrigeration module 5 includes a water storage tank 51, within which a water storage cavity 51a is formed. The water storage cavity 51a is connected to the outlet side of the pure water tank 3. Water from the pure water tank 3 can flow into the water storage tank 51 through a pipe (i.e., the water supply path 12), and the water in the water storage tank 51 is cooled by the relevant refrigeration structure of the refrigeration module 5. The water storage cavity 51a is also connected to the water outlet 61 through a first water outlet path 14, allowing the cooled water to flow out through the water outlet 61 for user consumption. The first water outlet path 14 is equipped with a first water pump 40 to power the water flow in the first water outlet path 14; the third water pump 60 is equipped with a third water pump 60 to power the water in the third water supply path 12, so as to pump the pure water in the pure water tank 3 to the storage tank 51. The first water pump 40 and the third water pump 60 can be diaphragm pumps. Similarly, the user can select the temperature of the cold water according to their needs, such as, but not limited to, 1℃, 3℃, 5℃, and 8℃.

[0050] It is worth mentioning that the water purifier's casing 200 also features a return water path 13, which connects the water storage chamber 51a and the filter module 2. Water in the water storage tank 51 can flow back to the filter module 2 for filtration via the return water path 13. It should be noted that the water in the water storage tank 51 is water from the pure water tank 3 that flows into the water storage chamber 51a through the water replenishment path 12. In other words, the water in the water storage chamber 51a has already been filtered by the filter module 2. However, if the water in the water storage chamber 51a is not used for a long time, or during the water purification process, the heating module 4 or compressor inside the casing 200 will release heat, causing the insulation or protective layer's molecular materials to evaporate and enter the water through the tank or pipes. This can result in an unpleasant odor and poor water quality and taste. Therefore, the return water path 13 allows the water in the water storage tank 51 to flow back to the filter module 2 for filtration, thereby improving the water quality and taste.

[0051] The technical solution of this utility model connects the water storage tank 51 of the cooling module 5 and the filter module 2 through the return water path 13, so that the water in the water storage tank 51 can flow back to the filter module 2 through the return water path 13 for filtration, thereby eliminating the odor of the water in the water storage tank 51, improving the water quality and taste, and enhancing the user's water experience.

[0052] Please see Figures 1 to 8 In one embodiment, the filtration module 2 includes a composite filter element 21, which includes a pre-filter element 211 and a post-filter element 212. The outlet side of the post-filter element 212 is connected to the pure water tank 3, and the return water path 13 is connected to the water storage tank 51 and the inlet side of the post-filter element 212.

[0053] Specifically, the filtration module 2 includes a composite filter element 21, which includes a pre-filter element 211 and a post-filter element 212. The pre-filter element 211 is located upstream of the post-filter element 212, and the outlet side of the post-filter element 212 is connected to the pure water tank 3. The water filtered by the post-filter element 212 can flow directly into the pure water tank 3. The return water path 13 is connected to the water storage chamber 51a of the water storage tank 51 and the water inlet side of the post-filter 212. That is to say, the water in the water storage chamber 51a can be discharged to the post-filter 212 for filtration through the return water path 13. This design reduces the flow path of the water in the water storage chamber 51a when it is filtered again. On the other hand, since the purpose of filtering the water in the water storage chamber 51a again is to remove the odor in the water and improve the water quality and taste, the aforementioned filtration effect can be achieved by the post-filter 212. Therefore, the return water path 13 can be directly connected to the water inlet side of the post-filter 212, which also ensures the service life of the pre-filter 211.

[0054] The pre-filter 211, also known as a pre-filter, is installed at the very beginning of the water system. Its main function is to remove large particulate impurities from the water, such as suspended solids, sediment, and rust. If these impurities flow directly downstream, they can damage equipment and shorten its lifespan. Therefore, the pre-filter 211 protects downstream equipment and improves overall water quality. In addition, the pre-filter 211 can also remove some organic matter, residual chlorine, and off-colors and odors, providing more favorable conditions for subsequent deep purification. The post-filter 212 is usually located at the final stage of the water system, responsible for further removing impurities and odors from the water, improving its taste and purity. Through its sophisticated filter material and adsorption capacity, the post-filter 212 can further remove these residues, making the water clearer, purer, and with a better taste. At the same time, the post-filter 212 can also prevent impurities and contaminants from accumulating in downstream equipment, thereby extending the equipment's lifespan.

[0055] Please see Figure 1 and Figure 8 In one embodiment, the return water path 13 is equipped with a return pump 10 to pump water from the water storage tank 51 to the post-filter cartridge 212 for filtration. Specifically, the return pump 10 is located in the flow path between the water storage chamber 51a and the inlet side of the post-filter cartridge 212, i.e., on the return water path 13, to pump water from the water storage chamber 51a to the post-filter cartridge 212 for filtration. The type of return pump 10 can be a diaphragm pump.

[0056] Please see Figure 1 and Figure 5 In one embodiment, the water storage tank 51 is further provided with a sterilization module 7 for sterilizing the water in the water storage tank 51. Specifically, the sterilization module 7 is located in the water storage cavity 51a of the water storage tank 51. The sterilization module 7 can kill and inhibit the growth of bacteria, viruses and other microorganisms in the water storage cavity 51a, thereby ensuring the safety and hygiene of the water quality. At the same time, since the return water path 13 connects the water storage cavity 51a and the filter module 2, the water in the water storage tank 51 can be returned to the filter module 2 for filtration through the return water path 13. The water filtered by the filter module 2 will flow into the pure water tank 3. That is, the water sterilized by the sterilization module 7 in the water storage cavity 51a will flow into the pure water tank 3. In other words, the water in the pure water tank 3 is also water sterilized by the sterilization module 7.

[0057] Furthermore, the sterilized water in the pure water tank 3 flows into the storage chamber 51a, where it is sterilized again by the sterilization module 7. The water in the storage chamber 51a then flows back to the pure water tank 3 through the return water path 13 and the filter module. In other words, the water in the pure water tank 3 flows into the storage chamber 51a, then through the return water path 13 to the filter module 2 for filtration, and finally flows back to the pure water tank 3. The entire water path is a circulating water path 18. The sterilization module 7 installed in the storage chamber 51a can sterilize the water in both the storage chamber 51a and the pure water tank 3, eliminating the need for a separate sterilization module 7 in the pure water tank 3, thus reducing the number of sterilization modules 7 required.

[0058] Please see Figure 1 In one embodiment, the filtration module 2 further includes a reverse osmosis filter element 22, the inlet side of the reverse osmosis filter element 22 is connected to the outlet side of the pre-filter element 211, and the pure water outlet side of the reverse osmosis filter element 22 is connected to the inlet side of the post-filter element 212; the water system 100 of the water purifier further includes a wastewater water path 16, which is connected to the wastewater outlet side of the reverse osmosis filter element 22 and the raw water tank 1.

[0059] Specifically, the reverse osmosis filter element 22 is located between the pre-filter element 211 and the post-filter element 212. The reverse osmosis filter element 22 is one of the core components of the filtration system. It utilizes the principle of reverse osmosis, separating solutes from solvents in water through the selective retention of a semi-permeable membrane. Specifically, the reverse osmosis filter element 22 can remove impurities such as metal ions, bacteria, viruses, and organic matter from the water, thereby obtaining high-quality drinking water. This filter element has a very thorough filtration effect, effectively improving water quality and safety.

[0060] The end of the filter module 2 is equipped with a water circuit board (not shown in the figure). This water circuit board has multiple water circuit interfaces connecting the inlet and outlet sides of the pre-filter 211, post-filter 212, and reverse osmosis filter 22. Specifically, the water circuit board has a pre-filter inlet, a pre-filter outlet, a reverse osmosis filter inlet, a wastewater outlet, and a post-filter outlet. The wastewater circuit 16 is connected to both the wastewater outlet and the raw water tank 1, so that the wastewater produced after filtration by the reverse osmosis filter 22 flows into the raw water tank 1.

[0061] Furthermore, the water storage tank 51 is provided with a first water outlet (not marked in the figure), which is connected to the water storage chamber 51a. A water flow channel is also formed in the water circuit board, which connects the pure water outlet side of the reverse osmosis filter element 22 and the water inlet side of the post-filter element 212. The water circuit board is also provided with a return port, which is used to connect to the return water circuit 13 and is connected to the water flow channel, so that the water storage chamber 51a can be connected to the water inlet side of the post-filter element 212 through the return water circuit 13.

[0062] In one embodiment, the water system 100 of the water purifier further includes at least one multi-way valve (not shown in the figure). The multi-way valve includes a first interface, a second interface and a third interface. The first interface is connected to the water storage chamber 51a, the second interface is connected to the water outlet side of the pure water tank 3, and the third interface is connected to the return port and the water outlet 61.

[0063] Specifically, the water system 100 of the water purifier can also be equipped with a multi-way valve. One interface of the multi-way valve is connected to the water storage chamber 51a, and the other interfaces are connected to the pure water tank 3, the return port and the outlet 61. The multi-way valve realizes the connection between the water storage chamber 51a and the pure water tank 3, the return port and the outlet 61. This setting can reduce the design of water interface on the water storage tank 51, and further rationally plan the routing and layout of the pipeline inside the shell 200 through the multi-way valve, optimize the pipeline layout, and avoid multiple pipelines being directly connected to the water storage chamber 51a through the water interface on the water storage tank 51.

[0064] Furthermore, the multi-way valve is a three-way valve, with two three-way valves. One three-way valve has a first port, a second port, and a third port, while the other three-way valve has a fourth port, a fifth port, and a sixth port. The fourth and third ports are connected, the fifth port is connected to the return port, and the sixth port is connected to the outlet 61. Thus, through the design of the two three-way valves, the first port of the first three-way valve is connected to the water storage chamber 51a, the second port is connected to the inlet of the water storage chamber 51a, and the third port is connected to the outlet of the water storage chamber 51a. The inlet refers to the water path through which external water enters the water storage chamber 51a, i.e., the water flowing from the pure water tank 3 to the water storage tank 51. The outlet refers to the water path through which the water in the water storage tank 51 flows outward, including the water in the water storage chamber 51a flowing back to the post-filter element 212 and the water in the water storage chamber 51a flowing to the outlet 61 for user use. Since the water outlet includes two outlets, there are two three-way valves. The fourth and third ports of the second three-way valve are connected, the fifth port is connected to the return port, and the sixth port is connected to the outlet 61, so as to realize the function of the aforementioned water outlet.

[0065] Please see Figure 1 In one embodiment, the raw water tank 1 includes a raw water storage area 11 and a wastewater storage area 12. The inlet of the filter water path 11 is connected to the raw water storage area 11, and the outlet of the wastewater path 16 is connected to the wastewater storage area 12. Specifically, a partition plate 13 is provided inside the raw water tank 1 to divide the chamber inside the raw water tank 1 into the raw water storage area 11 and the wastewater storage area 12. The partition plate 13 has a certain height to avoid the TDS value of the raw water being affected by the wastewater.

[0066] Please see Figure 1 and Figure 7In one embodiment, the water system 100 of the water purifier further includes a balancing water path 17, which is connected to the inlet side of the pure water tank 3 and the storage tank 51. Specifically, the balancing water path 17 is connected to the inlet side of the pure water tank 3 and the storage tank 51. The design of the balancing water path 17 can prevent excessive water from overflowing from the storage tank 51 in the pure water tank 3. The pure water tank 3 has a maximum water level and a minimum water level. When the water level in the pure water tank 3 exceeds the maximum water level, the excess water can be discharged into the storage tank 51 through the balancing water path 17 to prevent water from overflowing from the pure water tank 3.

[0067] Furthermore, the balancing water path 17 is equipped with a balancer to monitor the water level in the pure water tank 3. When there is too much water in the pure water tank 3, the excess water is drained into the storage tank 51. Specifically, the balancer includes at least a first balancer 17a and a second balancer 17b. The first balancer 17a and the second balancer 17b are used to monitor the minimum and maximum water levels in the pure water tank 3, respectively, so that when the pure water in the pure water tank 3 is insufficient, water can be added to it, and when there is too much pure water, it can be drained into the storage chamber 51a through the balancing water path 17.

[0068] Please see Figure 1 and Figure 8 In one embodiment, the water system 100 of the water purifier further includes a booster pump 20, which is disposed in the filtration water path 11 and located in the flow path between the filtration module 2 and the raw water tank 1. Specifically, a booster pump 20 is also provided in the flow path between the filtration module 2 and the raw water tank 1. The booster pump 20 can be a diaphragm pump, and the booster pump 20 can provide water pressure power for the water system.

[0069] Please see Figures 1 to 8 In one embodiment, the water system 100 of the water purifier further includes a circulating water path 18 and an ice-making module 8. The circulating water path 18 connects the water storage tank 51 and the ice-making module 8 to draw water from the water storage tank 51 to the ice-making module 8 for ice making. Specifically, to enrich the functions of the water purifier and improve the user experience, the water system 100 of the water purifier further includes an ice-making module 8, and the water storage tank 51 and the ice-making module 8 are connected through the circulating water path 18 to ensure that water from the water storage tank 51 can be drawn to the ice-making module 8 for ice making.

[0070] Please see Figure 1 and Figure 6In one embodiment, an ice storage chamber 91 is provided inside the water storage tank 51, and a water storage cavity 51a is formed below the ice storage chamber 91. The ice-making module 8 is disposed above the ice storage chamber 91; one end of the circulating water passage 18 is connected to the water storage cavity 51a. Specifically, the ice storage chamber 91 is provided inside the water storage tank 51, and the ice storage chamber 91 is used to store ice blocks made by the ice-making module 8. The ice storage chamber 91 divides the internal space of the water storage tank 51 into upper and lower parts. The lower part of the ice storage chamber 91 is the water storage cavity 51a, and the ice-making module 8 is installed above the ice storage chamber 91. The ice blocks made by the ice-making module 8 can fall directly into the ice storage chamber 91 for storage. The water purifier housing 200 is also provided with an ice outlet 62, which is located on the front side of the housing 200. The ice outlet 62 is connected to the ice storage chamber 91, and the ice storage chamber 91 is provided with an ice dispensing component 92. When the user needs to obtain ice, the ice dispensing component 92 works to move the ice in the ice storage chamber 91 to the ice outlet 62 for the user to use.

[0071] Please continue reading. Figure 1 and Figure 6 In one embodiment, the ice-making module 8 includes an ice maker 81 and an ice-making box 82. The ice maker 81 is positioned above the ice-making box 82, and the other end of the circulating water passage 18 is connected to the ice-making box 82 to draw water from the water storage chamber 51a into the ice-making box 82 for ice making. Specifically, the ice maker 81 is located above the ice-making box 82, and the ice maker 81 extends at least partially into the ice-making box 82 for ice making. Further, a circulating pump 30 is provided on the circulating water passage 18 to pump water from the water storage chamber 51a into the ice-making module 8 for ice making. Specifically, the circulating pump 30 can pump water from the water storage chamber 51a into the ice-making module 8 for ice making.

[0072] It should be noted that during the ice-making process, the water pumped from the water storage chamber 51a to the ice-making module 8 by the circulation pump 30 is flowing water. This means the water in the water storage chamber 51a is continuously pumped to the ice-making box 82 by the circulation pump 30. The ice maker 81 first cools the water in the ice-making box 82 during the ice-making process. Because the water in the water storage chamber 51a continuously flows into the ice-making box 82, the low-temperature water in the ice-making box 82, after being cooled by the ice maker 81, overflows and flows back into the water storage chamber 51a through the ice storage compartment 91 or other drainage structures. The water in the water storage chamber 51a and the ice-making box 82 is in a dynamic circulation process; the ice maker 81 simultaneously performs the functions of ice making and cooling the water in the water storage chamber 51a.

[0073] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
