Description

Technical Field

[0001] This application relates to the field of water purifier technology, and in particular to wall-mounted water purifiers and water circuit systems used therein. Background Technology

[0002] With economic development, various innovative water purification and drinking water devices have emerged in the market. These devices use different technologies to purify and improve water quality, ensuring that people can drink healthy and harmless water. They have greatly improved the cleanliness of drinking water in homes and public places. The design and installation methods of household water purifiers are also constantly innovating to adapt to the needs and spatial layouts of different families. Currently, the most common installation forms of water purifiers on the market are under-sink, wall-mounted, and freestanding. Wall-mounted water purifiers are installed on the wall, saving floor space. Because of their reasonable installation location, they do not occupy valuable floor or countertop space, so related products on the market are gradually increasing.

[0003] In related technologies, traditional wall-mounted water purifiers typically treat and purify raw water through a single filtration and purification path. However, this path is difficult to meet the needs of high-flow-rate water use, and when the reverse osmosis filter fails, the entire water system will stop working, affecting the overall performance and water production efficiency of the wall-mounted water purifier. Utility Model Content

[0004] Therefore, it is necessary to provide a wall-mounted water purifier and its water system to address the aforementioned technical problems, so as to improve the overall performance and water production efficiency of the water purifier.

[0005] The first aspect of this application provides a water system for a wall-mounted water purifier. The water system includes a pre-filter, an inlet solenoid valve, a booster pump, a reverse osmosis filter, and a post-filter connected in sequence. The pre-filter is connected to the raw water inlet, and the post-filter is connected to the pure water outlet. At least two reverse osmosis filters and booster pumps are provided, with each booster pump connected to each reverse osmosis filter. At least two booster pumps and at least two reverse osmosis filters are arranged in parallel between the inlet solenoid valve and the post-filter.

[0006] The aforementioned water system uses a pre-filter to initially filter the raw water flowing in from the inlet, then the water flows through an inlet solenoid valve into a booster pump. After being pressurized by the booster pump, the water is output to the corresponding reverse osmosis filter. The reverse osmosis filter purifies the water to produce pure water, which is then further filtered by a post-filter before being output to the pure water outlet. This allows for flexible control of the purification path and precise management of unidirectional flow. By using at least two booster pumps and at least two reverse osmosis filters, the system ensures that even if one filter fails, the others can still function normally, guaranteeing continued water supply. Furthermore, when a large flow rate is required, the simultaneous operation of these two booster pumps and filters increases the purification efficiency and volume of the raw water, meeting the demands of high-flow water usage and thus improving the overall performance and water production efficiency of the water purifier.

[0007] In one embodiment, the water system further includes at least two regulating valves, each of which is disposed between the booster pump and the post-filter, and each regulating valve and each reverse osmosis filter are connected in parallel.

[0008] In one embodiment, the water system further includes a mixing channel, with at least two regulating valves and at least two reverse osmosis filter cartridges having their pure water outlets connected upstream of the mixing channel.

[0009] In one embodiment, the water system further includes a first check valve and a water storage tank. The first check valve is located downstream of the post-filter and the mixing channel, and the water storage tank is located upstream of the mixing channel and between the first check valve.

[0010] In one embodiment, the water system further includes at least two second check valves, each second check valve being connected between the pure water outlet and the upstream of the mixing channel of each reverse osmosis filter element, and each second check valve being connected in parallel to each regulating valve.

[0011] In one embodiment, the water system further includes at least two wastewater solenoid valves, each wastewater check valve being connected to the wastewater outlet of each reverse osmosis filter element, and the at least two wastewater solenoid valves being disposed between the wastewater outlet and the wastewater effluent end of the reverse osmosis filter element.

[0012] In one embodiment, water flowing out of the pure water outlet via the regulating valve and the reverse osmosis filter cartridge can be mixed in the mixing channel to form mixed water before flowing out through the post-filter cartridge; the water system also includes at least one of the following:

[0013] The water system also includes a first detection element, which is located between the inlet solenoid valve and the booster pump. The first detection element is used to detect the TDS value of the water flowing out of the pre-filter.

[0014] The water system also includes a second detection element, which is disposed on the mixing channel and is used to detect the TDS value of the mixed water; the water system also includes a first pressure detection element, which is disposed on the mixing channel and is used to detect the water pressure of the mixed water.

[0015] The water system also includes a second pressure detection element, which is located between the pre-filter and the inlet solenoid valve. The second pressure detection element is used to detect the water pressure of the water flowing out of the pre-filter.

[0016] The water system also includes a flow meter, which is located downstream of the mixing channel and between the post-filter cartridge. The flow meter is used to obtain the flow rate of the mixed water.

[0017] In one embodiment, the water system further includes a bypass unit, which includes a bypass pipe and a bypass switch. The bypass inlet of the bypass pipe is connected between the pre-filter and the inlet solenoid valve, and the bypass outlet of the bypass pipe is connected between the pure water outlet of at least two reverse osmosis filters and the post-filter. The bypass switch is installed on the bypass pipe and is used to control the opening or closing of the bypass inlet and bypass outlet.

[0018] In one embodiment, the bypass switch is one of a ball valve, butterfly valve, gate valve, and globe valve.

[0019] A second aspect of this application provides a wall-mounted water purifier, comprising: a housing; and a water system for the wall-mounted water purifier as described above, at least a portion of the water system being housed within the housing. Attached Figure Description

[0029] See Figure 1 The water system 10 is used to realize the filtration and purification function of the wall-mounted water purifier. The water system 10 includes a pre-filter 11, an inlet solenoid valve 12, a booster pump 13, a reverse osmosis filter 14, and a post-filter 16 connected in sequence. The pre-filter 11 is connected to the raw water inlet 1, and the post-filter 16 is connected to the pure water outlet 2.

[0030] The pre-filter 11 performs preliminary filtration of large particulate impurities, such as silt, rust, and suspended solids, in the raw water entering from the raw water inlet 1, preventing these impurities from clogging or damaging the reverse osmosis filter 14. The inlet solenoid valve 12 controls the flow of the filtered raw water into the reverse osmosis filter 14. The booster pump 13 pressurizes the water to meet the pressure requirements for reverse osmosis.

[0031] The raw water filtered by the pre-filter 11 is further purified by the reverse osmosis filter element 14. Typically, the reverse osmosis filter element 14 contains a reverse osmosis membrane. The raw water is passed through the reverse osmosis membrane under pressure, causing most pollutants to be blocked on one side of the membrane. Only pure water flows out through the membrane. The reverse osmosis membrane can remove most dissolved salts, heavy metals, organic matter, etc., thus purifying the raw water so that the pure water flowing out of the wall-mounted water purifier can meet the requirements for drinking water.

[0032] The post-filter 16 further refines the pure water filtration, improving its taste and odor, while removing trace contaminants that may remain from the reverse osmosis process, yielding the desired drinking water, which is then output through the pure water outlet 2. It should be noted that the pre-filter 11 and post-filter 16 can be integrated to form a composite filter, or they can be installed separately; furthermore, the pre-filter 11 and post-filter 16 can have various structures, which can be selected according to purification needs, and this application does not impose any limitations.

[0033] The raw water flowing into the raw water inlet 1 is initially filtered by the pre-filter cartridge 11, and then flows into the booster pump 13 through the inlet solenoid valve 12. After being pressurized by the booster pump 13, it is output to the reverse osmosis filter cartridge 14 connected to the booster pump 13. Pure water is obtained by the reverse osmosis filter cartridge 14. Finally, the pure water is further filtered by the post-filter cartridge 16 and output to the pure water outlet 2, thereby realizing flexible control of the purification path and precise management of unidirectional flow.

[0034] Furthermore, at least two reverse osmosis filter cartridges 14 and booster pumps 13 are provided, with each booster pump 13 connected to each reverse osmosis filter cartridge 14. At least two booster pumps 13 and at least two reverse osmosis filter cartridges 14 are arranged in parallel between the inlet solenoid valve 12 and the post-filter cartridge 16, so that the inlet solenoid valve 12 and each set of booster pumps 13 and reverse osmosis filter cartridges 14 form a purification path.

[0035] By configuring at least two booster pumps 13 and at least two reverse osmosis filter elements 14, the water system 10 has at least two purification paths. On the one hand, when one reverse osmosis filter element 14 fails, the other reverse osmosis filter elements 14 can still work normally, ensuring normal water supply even when one reverse osmosis filter element 14 fails. On the other hand, when a large flow of water is required, the simultaneous operation of at least two booster pumps 13 and at least two reverse osmosis filter elements 14 can improve the purification efficiency and volume of raw water to meet the demand for large flow of water, thereby improving the overall performance and water production efficiency of the wall-mounted water purifier.

[0036] In a feasible embodiment, the water system 10 further includes at least two regulating valves 18, which are disposed between the booster pump 13 and the post-filter 16, and each regulating valve 18 and each reverse osmosis filter 14 are connected in parallel.

[0037] The regulating valve 18 allows part of the water pressurized by the booster pump 13 to flow out directly through the regulating valve 18, while the other part is purified into pure water by the reverse osmosis filter element 14 before flowing out. The pure water obtained by the reverse osmosis filter element 14 and the water flowing out through the regulating valve 18 can be mixed to obtain mixed water with a certain total dissolved solids (TDS).

[0038] By adjusting the opening degree of the regulating valve 18, the pressurized water flows to the regulating valve 18 and the reverse osmosis filter element 14 in different proportions. Thus, the TDS value of the mixed water can be adjusted by the regulating valve 18 to meet the water quality requirements in different scenarios.

[0039] Each regulating valve 18 is connected to each reverse osmosis filter element 14, so that the amount of water entering different reverse osmosis filter elements 14 can be adjusted through different regulating valves 18, making the TDS adjustment of the mixed water more accurate and reliable.

[0040] To facilitate the mixing of water flowing out through regulating valve 18 and pure water purified by reverse osmosis filter element 14, water system 10 has a mixing channel 4. At least two regulating valves 18 and at least two pure water outlets 141 of reverse osmosis filter elements 14 are connected to the upstream of the mixing channel 4, so that water flowing out through at least two regulating valves 18 and pure water purified by at least two reverse osmosis filter elements 14 can mix in the mixing channel 4 to form mixed water.

[0041] The setting of the mixing channel 4 helps to simplify the number of pipes in the water system 10, reduce the volume occupied by the water system 10, realize the compact setting of the water system 10, reduce the overall cost of the water system 10, and facilitate the output of the mixed water obtained by mixing through multiple regulating valves 18 and multiple reverse osmosis filter elements 14 to the pure water outlet 2.

[0042] It is understood that it is a preferred embodiment that at least two regulating valves 18 and at least two reverse osmosis filter cartridges 14 have their pure water outlets 141 connected to the upstream of the mixing channel 4; in other embodiments, each regulating valve 18 and the corresponding reverse osmosis filter cartridge 14 may first be mixed to obtain mixed water, and then multiple sets of mixed water may be mixed.

[0043] In a feasible embodiment, the water system 10 further includes a first one-way valve 15 and a water storage tank 197, which is used to store mixed water. The water storage tank 197 is located upstream of the mixing channel 4 and between the first one-way valve 15, so that some of the mixed water in the mixing channel 4 can enter the water storage tank 197. By storing a certain amount of purified water in the water storage tank 197, users can access it at any time. At the same time, the water storage tank 197 can provide a stable water pressure, making the water flow more stable and continuous when users use the mixed water, resulting in a better user experience.

[0044] The first one-way valve 15 is located between the bypass outlet 1711 and the downstream of the mixing channel 4. Through the setting of the first one-way valve 15, part of the mixed water in the mixing channel 4 can flow stably through the first one-way valve 15 to the post-filter 16, thereby realizing the stable diversion of the mixed water in the mixing channel 4.

[0045] In an optional embodiment, the water system 10 further includes at least two second check valves 194, each second check valve 194 being connected between the pure water outlet 141 of each reverse osmosis filter element 14 and the upstream of the mixing channel 4, and each second check valve 194 being connected in parallel to each regulating valve 18.

[0046] The second one-way valve 194 ensures that the purified water after passing through each reverse osmosis filter element 14 can flow stably into the mixing channel 4. At the same time, the second one-way valve 194 limits the flow direction of the purified water, so that a unidirectional flow path of purified water is formed between the inlet solenoid valve 12, the booster pump 13, the reverse osmosis filter element 14 and the second one-way valve 194, preventing the purified water from flowing back into the reverse osmosis filter element 14.

[0047] Furthermore, the water system 10 also includes a first detection element 190, which is disposed between the inlet solenoid valve 12 and the booster pump 13. The first detection element 190 is used to detect the TDS value of the water flowing out of the pre-filter 11.

[0048] To obtain the TDS value of the mixed water, the water system 10 also includes a second detection element 191, which is disposed on the mixing water channel 4 and is used to detect the TDS value of the mixed water.

[0049] Optionally, all regulating valves 18 are electrically controlled regulating valves 18. The operating state of the regulating valve 18 is associated with the first detection element 190 and the second detection element 191. Based on the measurement results of the first detection element 190 and the second detection element 191, the operating state of the regulating valve 18 can be adjusted to control and regulate the TDS value of the outflowing mixed water to meet different water quality requirements.

[0050] In an optional embodiment, the water system 10 further includes a first pressure detection element 192, which is disposed in the flow channel between the regulating valve 18 and the first one-way valve 15. The first pressure detection element 192 is used to detect the water pressure of the mixed water, thereby obtaining the water pressure of the mixed water. The water pressure of the mixed water can be used to control the water production process of the reverse osmosis filter element 14. At the same time, when the water pressure of the mixed water is too high, the first pressure detection element 192 can stop the water system 10 to avoid damage to the water system 10 due to excessive water pressure. Optionally, the first pressure detection element 192 can be a pressure valve, an electrically controlled pressure switch, or a pressure sensor.

[0051] In an optional embodiment, the water system 10 further includes a second pressure detection element 193, which is disposed between the pre-filter 11 and the inlet solenoid valve 12. The second pressure detection element 193 is used to detect the water pressure of the water flowing out of the pre-filter 11, so that the booster pump 13 can pressurize the water filtered by the pre-filter 11 based on the water pressure value of the second pressure detection element 193, thereby avoiding damage to the reverse osmosis filter element 14 due to excessive water pressure. At the same time, when the water pressure flowing out of the pre-filter 11 is too high, the second pressure detection element 193 can prevent water from flowing in, thus avoiding damage to the water system 10 due to excessive water pressure. Optionally, the second pressure detection element 193 can be a pressure valve, an electrically controlled pressure switch, or a pressure sensor.

[0052] In an optional embodiment, the water system 10 further includes at least two wastewater solenoid valves 195. The wastewater solenoid valves 195 are all disposed between the wastewater outlet 142 and the wastewater outlet 3 of the reverse osmosis filter element 14. Each wastewater check valve is connected to the wastewater outlet 142 of each reverse osmosis filter element 14, so that the wastewater generated by the corresponding reverse osmosis filter element 14 can be discharged through the corresponding wastewater solenoid valve 195.

[0053] In an optional embodiment, the water system 10 further includes a flow meter 196, which is disposed downstream of the mixing channel 4 and between the post-filter cartridge 16 to detect the flow rate of the mixed water. Based on the value of the flow meter 196, one or more reverse osmosis filter cartridges 14 are selected to work to meet the needs of different water consumption.

[0054] Since some of the water in the mixing channel 4 will flow into the water storage tank 197, preferably, the flow meter 196 is set between the first one-way valve 15 and the post-filter 16, so that the flow rate of the mixed water flowing out of the first one-way valve 15 can be obtained through the flow meter 196, and thus the flow rate of the mixed water flowing out of the pure water outlet 2 can be known.

[0055] In some embodiments, the water system 10 further includes a bypass unit 17, which includes a bypass pipe 171 and a bypass switch 172. The bypass inlet 1711 of the bypass pipe 171 is connected between the pre-filter 11 and the inlet solenoid valve 12, and the bypass outlet 1712 of the bypass pipe 171 is connected between the first check valve 15 and the post-filter 16. The bypass switch 172 is installed on the bypass pipe 171 and is used to control the opening or closing of the bypass inlet 1711 and the bypass outlet 1712.

[0056] By using the bypass unit 17, under normal circumstances, the bypass switch 172 controls the bypass inlet 1711 and bypass outlet 1712 of the bypass pipe 171 to be blocked. Raw water from the raw water inlet 1 can then pass through the pre-filter 11 and the inlet solenoid valve 12 into the reverse osmosis filter 14. After purification by the reverse osmosis filter 14, pure water is obtained and flows from the pure water outlet 141 of the reverse osmosis filter 14 through the post-filter 16 to the pure water outlet 2, meeting the user's drinking water needs under normal circumstances. In case of a malfunction in the wall-mounted water purifier, or... In special circumstances such as power outages, the inlet solenoid valve 12 closes, and the bypass switch 172 controls the bypass inlet 1711 and bypass outlet 1712 of the bypass pipe 171 to be connected, so that the raw water at the raw water inlet 1 can be directly introduced into the bypass inlet 1711 after being pre-filtered by the pre-filter 11, and then flow out from the bypass outlet 1712. After being further filtered by the post-filter 16, it flows out to the pure water outlet 141, so that users can still obtain water through the wall-mounted water purifier in special circumstances to meet their emergency water needs.

[0057] When the bypass inlet 1711 and bypass outlet 1712 of the bypass pipe 171 are connected, the first check valve 15 and the second check valve 194 enable one-way communication from the pure water outlet 141 of the reverse osmosis filter element 14 to the pure water outlet 2. During the process of transporting raw water through the bypass pipe 171, the first check valve 15 and the second check valve 194 can effectively prevent the raw water from flowing back into the reverse osmosis filter element 14, which helps to protect the reverse osmosis filter element 14 and reduces the possibility of damage to the reverse osmosis filter element 14 caused by the backflow of raw water in the bypass pipe 171 into the reverse osmosis filter element 14.

[0058] Optionally, the bypass switch 172 is one of a ball valve, butterfly valve, gate valve, and globe valve. The manually operated bypass switch 172 can prevent failure due to emergencies such as power outages, improving its reliability. Furthermore, in special circumstances such as a malfunction of the wall-mounted water purifier or a power outage, the bypass switch 172 can effectively open the bypass pipe 171 to supply water, meeting the user's emergency water needs.

[0059] For example, the water system 10 includes two reverse osmosis filter elements 14, and correspondingly, two booster pumps 13, two second check valves 194, and two wastewater solenoid valves 195 are provided. Raw water enters through the inlet solenoid valve 12 and is filtered through a purification path consisting of one of the sequentially connected booster pumps 13, reverse osmosis filter elements 14, and second check valves 194, and wastewater is discharged through one of the wastewater solenoid valves 195; alternatively, raw water enters through the inlet solenoid valve 12 and is filtered through two sequentially connected purification paths consisting of two booster pumps 13, reverse osmosis filter elements 14, and second check valves 194, and wastewater is discharged through two wastewater solenoid valves 195, thereby increasing the water production capacity of the water system 10 to meet the demand for high-flow water use. It should be noted that this application does not limit the number of reverse osmosis filter elements 14 to two; correspondingly, the number of booster pumps 13, second check valves 194, and wastewater solenoid valves 195 is the same as the number of reverse osmosis filter elements 14.

[0060] Under normal circumstances, the bypass switch 172 controls the bypass inlet 1711 and bypass outlet 1712 of the bypass pipeline 171 to be blocked. Raw water enters the pre-filter 11 through the raw water inlet 1, and after being filtered by the pre-filter 11, it flows out to the inlet solenoid valve 12. The water pressure of the water after being filtered by the pre-filter 11 is detected by the second pressure detection element 193, and then it enters one or both booster pumps 13 through the inlet solenoid valve 12. Before flowing into the two booster pumps 13, it passes through the first... The testing unit 190 measures the TDS content of the water after filtration by the pre-filter 11. The water is pressurized by one or both booster pumps 13. A portion of the pressurized water flows into the reverse osmosis filter 14 corresponding to the booster pump 13, and another portion flows into the regulating valve 18 corresponding to the booster pump 13. The purified water from one or both reverse osmosis filter 14 flows out through the second check valve 194 corresponding to the pure water outlet 141 of the reverse osmosis filter 14, and then flows into the pre-filter 11. Water flowing from one or two parallel regulating valves 18 converges and mixes in the mixing channel 4 to obtain mixed water. The TDS content of the mixed water is measured by the second detection element 191. Part of the mixed water in the mixing channel 4 flows into the flow meter 196 through the first one-way valve 15, and part of the mixed water in the mixing channel 4 flows out into the water storage tank 197. Before entering the first one-way valve 15 and the water storage tank 197, the water pressure of the mixed water is detected by the first pressure detection element 192. After the flow rate of the mixed water is measured by the flow meter 196, it flows into the post-filter element 16. After being filtered by the post-filter element 16, it flows out from the pure water outlet 2. The wastewater generated by one or two reverse osmosis filter elements 14 flows through one or two wastewater solenoid valves 195 connected to the wastewater outlet 142 of the reverse osmosis filter element 14 and then converges to the wastewater outlet 3 to flow out, so as to meet the user's drinking needs under normal conditions. The flow rate of the mixed water is adjusted by controlling the number of reverse osmosis filter elements 14 used to meet the user's water needs for different flow rates.

[0061] In special circumstances such as malfunction or power outage of the wall-mounted water purifier, the bypass switch 172 controls the bypass inlet 1711 and bypass outlet 1712 of the bypass pipe 171 to be connected. Raw water enters the pre-filter 11 through the raw water inlet 1, and after being filtered by the pre-filter 11, it flows to the bypass inlet 1711 of the bypass pipe 171, and then enters the flow meter 196 through the bypass outlet 1712 of the bypass pipe 171. After being filtered by the post-filter 16, it flows out from the pure water outlet 2, so that users can still obtain water through the wall-mounted water purifier in special circumstances to meet their emergency water needs.

[0062] As part of the same concept, this application also provides a wall-mounted water purifier. The wall-mounted water purifier has an external mounting surface, which is generally a vertically oriented wall, cabinet, or similar surface. The wall-mounted water purifier includes a water system 10 as described in the above embodiments and a housing (not shown). At least a portion of the water system 10 can be accommodated within the housing, which provides support and protection for the water system 10 and provides an installation location for it.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
