[0040] Water purifiers currently on the market are usually equipped with an insulation layer or a protective layer to keep the cold water in the water tank warm. However, when the water stored in the water tank is not used for a long time, the water will produce an odor. At the same time, when the water is heated or cooled in the water tank, the molecular materials of the insulation layer or the protective layer will evaporate during the heat dissipation of the heating module or the compressor, and evaporate into the water through the water tank or the pipe, causing the water to have an odor, affecting the water quality and taste, and giving users a bad water experience.

[0041] The present invention provides a water channel system of a water purifier, which is applied to the water purifier equipment. The water channel system can reflux water in a water tank and filter it again to solve the problem that the water in the water tank has peculiar smell and poor water quality.

[0042] See also 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 refrigeration module 5, and the refrigeration module 5 includes a water storage tank 51;

[0043] The raw water tank 1 and the pure water tank 3 are connected through the filter water path 11, the filter module 2 is arranged in the filter water path 11, and is located on the flow path between the raw water tank 1 and the pure water tank 3, the pure water tank 3 and the water storage tank 51 are connected through the water replenishment water path 12, the water storage tank 51 and the filter module 2 are connected through the return water path 13, the water storage tank 51 is connected with the water outlet 61 through the first water outlet water path 14, and the pure water tank 3 is connected with the water outlet 61 through the second water outlet water path;

[0044] The water replenishment waterway 12 is used to replenish the water in the pure water tank 3 into the water storage tank 51 , and the return waterway 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. An installation space for installing structures such as a filter module 2, a heating module 4, a refrigeration module 5, a water pump, and a pipeline is formed in the housing 200. A water outlet 61 is provided on the housing 200, and the water outlet 61 is used to discharge water for drinking by the user. Further, the water outlet 61 is provided on the front side of the housing 200, and the number of water outlets 61 is at least one. In the present embodiment, one water outlet 61 is provided, and the water outlet 61 can be used to discharge hot water, cold water, and normal temperature water, and the water of three water outlet temperatures flows out through one water outlet 61, thereby reducing the number of water outlets 61 and simplifying the structural design. Of course, in other embodiments, the number of the water outlets 61 can also be set to multiple, and there is no specific restriction on this.

[0046] The raw water tank 1 and the pure water tank 3 are both mounted on the housing 200 and are detachable relative to the housing 200, so that the user can replenish raw water and directly pick up the pure water tank 3 for use when a large amount of drinking pure water is needed. The raw water tank 1 and the pure water tank 3 are connected through a filter water path 11, wherein the raw water tank 1 is mainly used to contain raw water (i.e., tap water), and the raw water tank 1 serves as the water source of the water path system 100 of the water purifier, and the pure water tank 3 is mainly used to store water filtered by the filter module 2, and the filter module 2 is arranged on 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 disposed in the housing 200, and the water inlet side of the filter module 2 is connected to the water outlet side of the raw water tank 1, and the water outlet side of the filter module 2 is connected to the pure water tank 3. The water in the raw water tank 1 can be filtered by the filter module 2 and then flow to 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] The heating module 4 is arranged in the housing 200 and is located on the flow path between the pure water tank 3 and the water outlet 61. It should be noted that the heating module 4 is an instant heating module for heating the water flowing through. After the water in the pure water tank 3 flows through the heating module 4, the normal temperature water in the pure water tank 3 can be heated to high temperature water by the heating module 4, and flows out through the second water outlet waterway for users to drink. A second water pump 50 is provided on the second water outlet waterway to provide power for the water flow in the second water outlet waterway. The type of the second water pump 50 can be a diaphragm pump. The water temperature of the high temperature water can be selected by the user according to demand, for example but not limited to 45°C, 60°C, 75°C, 80°C, 85°C, 95°C, 100°C.

[0049] The refrigeration module 5 is disposed in the housing 200, and includes a water storage tank 51, wherein a water storage chamber 51a for storing water is formed in the water storage tank 51, and the water storage chamber 51a is connected to the water outlet side of the pure water tank 3. The water in the pure water tank 3 can flow into the water storage tank 51 through a pipeline (i.e., a water supply water path 12), and the water in the water storage tank 51 is cooled by the relevant refrigeration structure of the refrigeration module 5, and the water storage chamber 51a is also connected to the water outlet 61 through the first water outlet water path 14, so that the cooled water can flow out through the water outlet 61 for drinking by the user. The first water outlet waterway 14 is provided with a first water pump 40 to provide power for the water flow in the first water outlet waterway 14; the water replenishment waterway 12 is provided with a third water pump 60, which is used to provide power for the water in the water replenishment waterway 12 to pump the pure water in the pure water tank 3 into the water storage tank 51. The first water pump 40 and the third water pump 60 can be diaphragm pumps. Similarly, the water temperature of the cold water can be selected by the user according to the needs, for example but not limited to 1°C, 3°C, 5°C, 8°C.

[0050] It is worth mentioning that a reflux waterway 13 is also provided in the shell 200 of the water purifier, and the reflux waterway 13 connects the water storage chamber 51a and the filter module 2, and the water in the water storage tank 51 can flow back to the filter module 2 through the reflux waterway 13 for filtration. It should be noted that the water in the water storage tank 51 is the water in the pure water tank 3 flowing into the water storage chamber 51a through the water replenishment waterway 12, that is, the water in the water storage chamber 51a is the water filtered by the filter module 2, and when the water in the water storage chamber 51a is not used for a long time, and during the water making process of the water purifier, the heating module 4 or the compressor in the shell 200 is in the process of heat dissipation, the molecular materials of the thermal insulation layer or the protective layer will volatilize and evaporate into the water through the water tank or the pipe, which will cause odor in the water, and the water quality and taste are poor. Therefore, by setting the reflux waterway 13, the water in the water storage tank 51 can be returned to the filter module 2 for filtration again to improve the water quality and taste.

[0051] The technical solution of the present invention connects the water storage tank 51 of the refrigeration module 5 and the filter module 2 through the reflux water channel 13, so that the water in the water storage tank 51 can flow back to the filter module 2 through the reflux water channel 13 for filtration, so as to eliminate the odor of the water in the water storage tank 51, improve the water quality and taste, and enhance the user's water use experience.

[0052] See also Figures 1 to 8 In one embodiment, the filter module 2 includes a composite filter element 21, the composite filter element 21 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 filter 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 water 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 reflux water path 13 is respectively connected to the water storage chamber 51a of the water tank 51 and the water inlet side of the post-filter element 212. That is to say, the water in the water storage chamber 51a can be discharged to the post-filter element 212 for filtration through the reflux water path 13. This design, on the one hand, reduces the flow path of the water when the water in the water storage chamber 51a 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 above-mentioned filtering effect can be achieved only through the action of the post-filter element 212. Therefore, the reflux water path 13 can be directly connected to the water inlet side of the post-filter element 212, while also ensuring the service life of the pre-filter element 211.

[0054] Among them, the pre-filter 211 is also commonly referred to as a pre-filter, which is a filter installed at the front end of the water system. Its main function is to remove large particles of impurities in the water, such as suspended matter, silt, rust, etc. If these impurities flow directly into the downstream of the water system, they may damage the equipment and shorten its service life. Therefore, the pre-filter 211 plays a role in protecting subsequent equipment and improving the overall water quality. In addition, the pre-filter 211 can also remove some organic matter, residual chlorine and foreign color and odor, providing more favorable conditions for subsequent deep purification. The post-filter 212 is usually located in the last process of the water system, responsible for further removing impurities and odors in the water and improving the taste and purity of the water. The post-filter 212 can further remove these residues through its sophisticated filtering materials and adsorption capacity, making the water clearer, purer and more delicious. At the same time, the post-filter 212 can also prevent impurities and pollutants in the water from accumulating in subsequent equipment, thereby extending the service life of the equipment.

[0055] See also Figure 1 and Figure 8 In one embodiment, the reflux waterway 13 is provided with a reflux pump 10 for pumping the water in the water storage tank 51 to the post-filter element 212 for filtration. Specifically, the reflux pump 10 is arranged on the flow path between the water storage chamber 51a and the water inlet side of the post-filter element 212, that is, arranged on the reflux waterway 13, so as to pump the water in the water storage chamber 51a to the post-filter element 212 for filtration. The type of the reflux pump 10 can be a diaphragm pump.

[0056] See also Figure 1 and Figure 5 In one embodiment, a sterilization module 7 is further provided in the water tank 51 to sterilize the water in the water tank 51. Specifically, the sterilization module 7 is provided in the water storage chamber 51a of the water tank 51. The sterilization module 7 can kill and inhibit the growth of bacteria, viruses and other microorganisms in the water storage chamber 51a, thereby ensuring the safety and sanitation of the water quality. At the same time, since the reflux waterway 13 connects the water storage chamber 51a and the filter module 2, the water in the water tank 51 can flow back to the filter module 2 through the reflux waterway 13 for filtration, and 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 chamber 51a will flow into the pure water tank 3, that is, the water in the pure water tank 3 is also sterilized by the sterilization module 7.

[0057] Furthermore, the sterilized water in the pure water tank 3 will flow into the water storage chamber 51a, and will be sterilized again through the sterilization module 7 in the water storage chamber 51a, and the water in the water storage chamber 51a will flow back to the pure water tank 3 through the return waterway 13 and the filter module. In other words, the water in the pure water tank 3 will flow into the water storage chamber 51a, and will flow to the filter module 2 through the return waterway 13 and will flow back to the pure water tank 3 after filtration. The entire waterway is a circulating waterway 18. The sterilization module 7 set in the water storage chamber 51a can sterilize the water in the water storage chamber 51a and the pure water tank 3, and there is no need to set the sterilization module 7 in the pure water tank 3 separately, thereby reducing the number of sterilization modules 7.

[0058] See also Figure 1 In one embodiment, the filter module 2 also includes a reverse osmosis filter element 22, the water inlet side of the reverse osmosis filter element 22 is connected to the water 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 water inlet side of the post-filter element 212; the water system 100 of the water purifier also includes a wastewater waterway 16, and the wastewater waterway 16 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 flow path of 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 uses the reverse osmosis principle to separate the solute from the solvent in the water through the selective interception of the semipermeable membrane. Specifically, the reverse osmosis filter element 22 can remove impurities such as metal ions, bacteria, viruses, organic matter, etc. in the water, thereby obtaining high-quality drinking water. The filtering effect of this filter element is very thorough, which can effectively improve the quality and safety of water.

[0060] The end of the filter module 2 is provided with a waterway plate (not shown in the figure), on which a plurality of waterway interfaces are provided for connecting the water inlet and water outlet sides of the pre-filter element 211, the post-filter element 212 and the reverse osmosis filter element 22. Specifically, the waterway plate is provided with a pre-filter element water inlet, a pre-filter element water outlet, a reverse osmosis filter element water inlet, a wastewater outlet and a post-filter element water outlet. The wastewater waterway 16 is respectively connected with the wastewater outlet and the raw water tank 1, so that the wastewater generated after filtering by the reverse osmosis filter element 22 flows into the raw water tank 1.

[0061] Furthermore, the water 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 channel connecting the pure water outlet side of the reverse osmosis filter element 22 and the water inlet side of the post-filter element 212 is also formed in the water circuit plate. A reflux port is also provided on the water circuit plate, which is used to connect the reflux water circuit 13, and the reflux port is connected to the water channel so that the water storage chamber 51a can be connected to the water inlet side of the post-filter element 212 through the reflux water circuit 13.

[0062] In one embodiment, the water system 100 of the water purifier also 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 reflux port and the water outlet 61.

[0063] Specifically, the water system 100 of the water purifier can also be provided with a multi-way valve, one interface in 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 reflux port and the water outlet 61. The connection between the water storage chamber 51a and the pure water tank 3, the reflux port and the water outlet 61 is achieved through the multi-way valve. Such a setting can reduce the design of the water channel interface on the water storage tank 51, and the direction and layout of the pipeline in the shell 200 can be further reasonably planned through the multi-way valve, and the pipeline layout is optimized to avoid multiple pipelines being directly connected to the water storage chamber 51a through the water channel interface on the water storage tank 51.

[0064] Further, the multi-way valve is a three-way valve, and two three-way valves are provided, one of which has a first interface, a second interface and a third interface, and the other three-way valve has a fourth interface, a fifth interface and a sixth interface, the fourth interface and the third interface are connected, the fifth interface is connected to the reflux port, and the sixth interface is connected to the water outlet 61. In this way, through the design of two three-way valves, the first interface of the first three-way valve is connected to the water storage chamber 51a, the second interface is connected to the water inlet of the water storage chamber 51a, and the third interface is connected to the water outlet of the water storage chamber 51a. The water inlet refers to the waterway for external water to be replenished in the water storage chamber 51a, that is, the water in the pure water tank 3 flows to the water storage tank 51. The water outlet refers to the waterway for the water in the water storage tank 51 to flow out, including the water in the water storage chamber 51a flowing back to the side of the post-filter 212, and the water in the water storage chamber 51a flowing to the water outlet 61 for users to use. Since the water outlet includes two water outlets, two three-way valves are provided. The fourth interface of the second three-way valve is connected to the third interface, the fifth interface is connected to the reflux port, and the sixth interface is connected to the water outlet 61 to achieve the function of the aforementioned water circuit.

[0065] See also Figure 1 In one embodiment, the raw water tank 1 includes a raw water storage area 11 and a waste water storage area 12. The water inlet end of the filtration waterway 11 is connected to the raw water storage area 11, and the water outlet end of the waste waterway 16 is connected to the waste water storage area 12. Specifically, a partition plate 13 is provided in the raw water tank 1 to separate the chamber in the raw water tank 1 into the raw water storage area 11 and the waste water storage area 12. The partition plate 13 has a certain height to prevent the TDS value of the raw water from being affected by the waste water.

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