DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0033] Nowadays, the device applied in the family with the function of softening water quality is a soft water device. The soft water produced by the soft water device is usually directly used by the user after preliminary filtration, for example, the soft water device is directly communicated with a water heating device such as a water heater, a wall-hanging stove, an electric water heater, etc., and the soft water is directly heated to provide hot water for the user.

[0034] However, the soft water only undergoes primary filtration, and the user cannot directly drink it, and the soft water still contains a large amount of sodium ions. After the soft water is heated, scale will be formed in the water heating device such as a water heater, a wall-hanging stove, an electric water heater, etc., and the pipeline in the bathroom, which is easy to cause pipeline blockage and also causes the heat exchange efficiency of the heating device to decay.

[0035] In order to solve the above technical problems, please refer to Figure 1A soft pure hot single water system is provided, which comprises a soft water system 002, a first filter core 501, a second filter core 502 and a hot water system 004 connected in series, the first filter core 501 is used for filtering the soft water flowing into the first filter core 501 from the soft water system 002, and the first filter core 501 is used for outputting the first filtered water to the second filter core 502, the second filter core 502 is used for filtering the first filtered water flowing into the second filter core 502, and the second filter core 502 is used for outputting the first pure water to the hot water system 004, the hot water system 004 is used for heating the first pure water flowing into the hot water system 004, and the hot water system 004 is used for supplying hot water to the user.

[0036] It can be understood that the soft water system 002 is a device for removing calcium and magnesium ions in water by using cation exchange resin to reduce the hardness of raw water, thereby achieving the effect of softening hard water. The input port of the soft water system 002 can be in communication with an external water source, for example, the input port of the soft water system 002 is in communication with tap water. After the tap water is in full contact with the resin layer in the soft water system 002 and ion exchange is performed, soft water can be formed. The soft water system 002 has a first output port and a second output port. The second output port can directly output soft water for the user to use, for example, for the user to wash fruits and vegetables, etc. The first output port can be in communication with the first filter core 501, so that the soft water flows into the first filter core 501.

[0037] It should be noted that although the water treated by the soft water treatment removes the hardness ions, it may contain other impurities, such as salt residues or other dissolved substances that may be added during the soft water process. The first filter core 501 can be a polypropylene cotton filter core or an activated carbon filter core, so that the first filter core 501 can be used to filter larger particulate matter, precipitates, etc. in the soft water. The first filter core 501 has a first port and a second port in communication with each other. The first port is in communication with the first output port, so that the first filter core 501 can be connected in series with the soft water system 002, so that the soft water after the tap water is softened by the soft water system 002 can flow into the first filter core 501. After the soft water is filtered by the first filter core 501, the first filtered water is formed and flows out of the second port.

[0038] In addition, the water treated by the soft water system 002 contains a high content of sodium ions, and the first filter core 501 may not be able to remove dissolved ions. The second filter core 502 can be a reverse osmosis membrane or an ultrafiltration membrane, so that the second filter core 502 can be used to remove dissolved salts, organic matter and microorganisms, etc. in the first filtered water. The second filter core 502 has a first port and a second port in communication with each other. The first port is in communication with the second port, so that the second filter core 502 is connected in series with the first filter core 501, and the second filter core 502 is located downstream of the first filter core 501. The first filtered water can flow into the second filter core 502. After the first filtered water is filtered by the second filter core 502, the first pure water is formed and flows out of the second port.

[0039] In this embodiment, the hot water system 004 has a first flow port and a second flow port in communication with each other, the first flow port is in communication with the second pipe port, so that the hot water system 004 is in series with the secondary filter element 502, and the hot water system 004 is located downstream of the secondary filter element 502, the first pure water can flow into the hot water system 004, and the first pure water is heated by the hot water system 004 to form hot water, and the hot water flows out of the second flow port for the user to use, therefore, the soft and pure hot single water system can ensure that the dissolved salts and the like in the water are removed before heating, so that there is no scale when heating, so as to not affect the heating efficiency and service life of the hot water system 004, and at the same time can ensure the purity of the water, and can be directly drunk by the user.

[0040] Specifically, the soft and pure hot single water system can further include a pure water outlet valve 0035, the pure water outlet valve 0035 can be in communication with the second pipe port, so that the pure water outlet valve 0035 can be used to directly provide the first pure water for the user to directly drink.

[0041] Please refer to Figure 1 In some embodiments, the primary filter element 501 can include a front filter element 5011 and a rear filter element 5012, the front filter element 5011 is in series between the soft water system 002 and the secondary filter element 502, the front filter element 5011 is used to filter the soft water flowing from the soft water system 002 into the front filter element 5011, and the front filter element 5011 outputs the first filtered water to the secondary filter element 502, the rear filter element 5012 is in series between the secondary filter element 502 and the hot water system 004, the rear filter element 5012 is used to filter the first pure water flowing from the secondary filter element 502 into the rear filter element 5012, and the rear filter element 5012 outputs the second pure water to the hot water system 004.

[0042] It should be noted that the front filter element 5011 and the rear filter element 5012 can process different pollutants respectively, for example, the front filter element 5011 can be a polypropylene cotton filter element, so that the front filter element 5011 can filter large particles, sediments and other impurities in the water, and the rear filter element 5012 can be an activated carbon filter element, so that the rear filter element 5012 can remove chlorine or organic matter in the water.

[0043] The front filter element 5011 can have a first port and a second port, the first port is in communication with the first output port, and the second port is in communication with the first pipe port, so that the front filter element 5011 can be in series between the soft water system 002 and the secondary filter element 502, the soft water softened from the soft water system 002 can flow into the front filter element 5011, the front filter element 5011 can filter large particles, sediments and other impurities in the soft water to form the first filtered water, and the first filtered water can flow into the secondary filter element 502.

[0044] The post-filter 5012 has a third port and a fourth port that are interconnected. The third port can be connected to the second pipe port, and the fourth port can be connected to the first outlet. This allows the post-filter 5012 to be connected in series between the secondary filter 502 and the hot water system 004. The first pure water formed after filtration by the secondary filter 502 can flow into the post-filter 5012. The post-filter 5012 can further purify the first pure water, such as by adsorbing odors or intercepting possible filter material. The post-filter 5012 can output second pure water, which has a better taste.

[0045] Please see Figure 1 In some embodiments, the soft water purification and heating single-channel system further includes a pure water return control component 0031. The first valve port of the pure water return control component 0031 is connected to the upstream of the secondary filter element 502 at a first connecting node a, and the second valve port of the pure water return control component 0031 is connected to the downstream of the secondary filter element 502 at a second connecting node. The pure water return control component 0031 is used to make the first pure water flow unidirectionally from the downstream of the secondary filter element 502 to the upstream of the secondary filter element 502.

[0046] Optionally, the first valve port and the second valve port of the pure water reflux control component 0031 are two interfaces of the pure water reflux control component 0031. The first connecting node a can have two interfaces that are mutually connected. The first interface of the first connecting node a is connected to the first valve port of the pure water reflux control component 0031, and the second interface of the first connecting node a is connected to the first pipe port of the secondary filter element 502, so that the first valve port of the pure water reflux control component 0031 is connected to the upstream of the secondary filter element 502.

[0047] The second connecting node b can have two mutually connected interfaces. The first interface of the second connecting node b is connected to the second valve port of the pure water return control component 0031, and the second interface of the second connecting node b is connected to the second pipe port of the secondary filter element 502. This allows the second valve port of the pure water return control component 0031 to be connected to the downstream of the secondary filter element 502. Furthermore, the pure water return control component 0031 can be a pure water return one-way valve. The pure water return control component 0031 can control its second valve port to flow unidirectionally to the first valve port. When the soft water purification and heating single-circuit system is not working, the first pure water can be controlled by the pure water return control component 0031 to flow unidirectionally from the downstream of the secondary filter element 502 to the upstream of the secondary filter element 502. This can form a water flow to flush the dirt on the filter membrane inside the secondary filter element 502, prevent the secondary filter element 502 from being blocked, and extend the service life of the secondary filter element 502.

[0048] Please see Figure 1In some embodiments, the first valve port of the pure water reflux control component 0031 is connected to the upstream of the secondary filter element 502 and the downstream of the pre-filter element 5011 at the first connecting node a, and the second valve port of the pure water reflux control component 0031 is connected to the downstream of the secondary filter element 502 and the upstream of the post-filter element 5012 at the second connecting node b.

[0049] Specifically, the first connection point is a three-way pipe with three interconnected interfaces. The first interface of the first connecting node a is connected to the first valve port of the pure water return control component 0031, the second interface of the first connecting node a is connected to the first pipe port of the secondary filter element 502, and the third interface of the first connecting node a is connected to the second port of the pre-filter element 5011. This allows the first valve port of the pure water return control component 0031 to be connected to the pipeline between the upstream of the secondary filter element 502 and the downstream of the pre-filter element 5011, which simplifies the pipeline layout between the secondary filter element 502 and the pre-filter element 5011.

[0050] The second connection point is a three-way pipe with three interconnected interfaces. The first interface of the second connecting node b is connected to the second valve port of the pure water return control component 0031, the second interface of the second connecting node b is connected to the second pipe port of the secondary filter element 502, and the third interface of the second connecting node b is connected to the third port of the post-filter element 5012. This allows the second valve port of the pure water return control component 0031 to be connected to the pipeline between the downstream of the secondary filter element 502 and the upstream of the post-filter element 5012, which simplifies the pipeline layout between the secondary filter element 502 and the post-filter element 5012.

[0051] Please see Figure 1 In some embodiments, the soft-cleaning and heating single-channel water system further includes a booster pump 70, which is connected in series between the pre-filter 5011 and the secondary filter 502, and the booster pump 70 is located downstream of the first connecting node a.

[0052] It should be noted that the soft water system, which is connected in series with the water softening system 002, the primary filter cartridge 501, the secondary filter cartridge 502, and the hot water system 004. The large number of treatment units connected in series will reduce the water pressure inside the soft water system, especially since the secondary filter cartridge 502 is a reverse osmosis filter cartridge. The secondary filter cartridge 502 requires a certain pressure to work, which makes the soft water system have high water pressure requirements.

[0053] In this embodiment, by connecting the booster pump 70 in series between the pre-filter 5011 and the secondary filter 502, the booster pump 70 can increase the water pressure inside the soft-clean-heat single-circuit water system to maintain the normal operation of the soft-clean-heat single-circuit water system. Furthermore, the booster pump 70 is located upstream of the secondary filter 502, so that the booster pump 70 can pressurize the secondary filter 502 to ensure that the secondary filter 502 can work normally.

[0054] In addition, the booster pump 70 is located downstream of the first connecting node a, so that the booster pump 70, the pure water return control unit 0031 and the secondary filter element 502 can form a loop. When the pure water return control unit 0031 controls the first pure water to flow unidirectionally from the downstream of the secondary filter element 502 to the upstream of the secondary filter element 502, the booster pump 70 can also increase the water pressure to drive the first pure water to form a water flow to flush the dirt on the filter membrane inside the secondary filter element 502.

[0055] Please see Figure 1 In some embodiments, the soft-cleaning and heating single-circuit water system further includes a filtered water outlet valve 503, which is connected in series between the pre-filter 5011 and the secondary filter 502. The filtered water outlet valve 503 is used to selectively connect the pre-filter 5011 and the secondary filter 502, and the filtered water outlet valve 503 is located upstream of the first connecting node a.

[0056] Specifically, by setting a filtered water outlet valve 503 between the pre-filter 5011 and the secondary filter 502, the filtered water outlet valve 503 can selectively control the flow between the pre-filter 5011 and the secondary filter 502, thereby facilitating the opening or closing of the entire soft, clean, and hot water single-circuit system. By setting the filtered water outlet valve 503 upstream of the first connecting node a, the filtered water outlet valve 503 is located upstream of the pure water return control component 0031, so that the filtered water outlet valve 503 will not affect the pure water return control component 0031. When the filtered water outlet valve 503 is in the closed state, or when the soft, clean, and hot water single-circuit system is closed, the pure water return control component 0031 can also control the first pure water to flow unidirectionally from the downstream of the secondary filter 502 to the upstream of the secondary filter 502, so as to flush the dirt on the filter membrane inside the secondary filter 502.

[0057] Please see Figure 1 In some embodiments, the soft water purification and heating single-channel system further includes a raw water quality detection element 040, which is connected in series between the pre-filter 5011 and the secondary filter 502. The raw water quality detection element 040 is used to detect the water quality of the first filtered water flowing into the secondary filter 502, and the raw water quality detection element 040 is located downstream of the first connecting node a.

[0058] It is understandable that the pre-filter 5011 may be damaged after long-term use of the soft water purification and heating single-circuit system. By connecting the raw water quality detection element 040 in series between the pre-filter 5011 and the secondary filter 502, the raw water quality detection element 040 can detect the first filtered water flowing out of the pre-filter 5011. When a large number of large particulate impurities are detected in the first filtered water, it indicates that the pre-filter 5011 has been damaged, and the raw water quality detection element 040 can issue the first warning to remind the user that the pre-filter 5011 needs to be replaced.

[0059] In addition, the raw water quality detection element 040 is set downstream of the first connecting node a, so that the raw water quality detection element 040 can be located between the first valve ports of the pure water return control element 0031. Thus, when the pure water return control element 0031 controls the first pure water to flow unidirectionally from downstream to upstream of the secondary filter element 502, the raw water quality detection element 040 can also detect the water quality of the first pure water. When the raw water quality detection element 040 detects that the concentration of dissolved substances in the first pure water is high, it indicates that the secondary filter element 502 is damaged, and the raw water quality detection element 040 can issue a second warning to remind the user that the secondary filter element 502 needs to be replaced.

[0060] Please see Figure 1 In some embodiments, the soft-cleaning and hot water single-circuit system further includes a pure water flow control component 0033, which is connected in series between the post-filter 5012 and the hot water system 004. The pure water flow control component 0033 is used to make the second pure water flow unidirectionally from the post-filter 5012 to the hot water system 004.

[0061] It should be noted that the post-filter 5012 is an activated carbon filter. If hot water flows back from the hot water system 004 into the post-filter 5012 when the soft and hot water system is closed, the activated carbon filter may shed carbon powder or grow bacteria due to prolonged contact with hot water.

[0062] In this embodiment, by connecting the pure water flow control component 0033 in series between the post-filter cartridge 5012 and the hot water system 004, and by using the pure water flow control component 0033 to make the second pure water flow unidirectionally from the post-filter cartridge 5012 to the hot water system 004, it is possible to prevent the hot water in the hot water system 004 from flowing back into the post-filter cartridge 5012 and to prevent bacteria from growing in the post-filter cartridge 5012.

[0063] Please see Figure 1 In some embodiments, the soft water purification hot water single-circuit system also includes a hot water tank replenishment valve 0041, which is connected in series between the pure water flow control component 0033 and the hot water system 004. The hot water tank replenishment valve 0041 is used to selectively connect the pure water flow control component 0033 and the hot water system 004.

[0064] In this embodiment, the hot water system 004 includes a hot tank assembly, which includes a tank body and a heating element. The tank body is connected to the fourth port of the post-filter 5012, allowing the second pure water to flow into the tank body. The heating element can then heat the second pure water. The amount of water in the tank body can affect the efficiency of hot water output. By connecting the hot tank water supply valve 0041 in series between the pure water flow control element 0033 and the hot water system 004, and by using the hot tank water supply valve 0041 to selectively connect the pure water flow control element 0033 and the hot water system 004, the amount of water in the tank body can be controlled through the hot tank water supply valve 0041, thereby further controlling the efficiency of hot water output.

[0065] Please see Figure 1 In some embodiments, the soft water purification and hot water single-circuit system also includes a pure water quality detection element 0034, which is connected in series between the post-filter 5012 and the hot water system 004. The pure water quality detection element 0034 is used to detect the water quality of the second pure water flowing into the hot water system 004.

[0066] Understandably, if the water is hard, scale is likely to form inside the tank of the hot water system 004, reducing its heating efficiency. By connecting the pure water quality detection element 0034 in series between the post-filter 5012 and the hot water system 004, the pure water quality detection element 0034 can detect the quality of the second pure water flowing into the hot water system 004. When it detects that the second pure water is hard, it can remind the user that the water quality of the second pure water does not meet the requirements, thus preventing scale formation inside the tank. In addition, it can also indicate that the secondary filter element 502 may be damaged, reminding the user to replace it.

[0067] Please see Figure 1 In some embodiments, the soft-cleaning hot water single-channel system also includes a water dispenser 006, which is connected downstream of the post-filter 5012.

The soft water valve 020 is connected to the resin tank 010 and has an inlet, a first outlet and a second outlet. The inlet is used to communicate with an external water source, the first outlet is used to output soft water to the primary filter cartridge 501, and the second outlet is used to supply soft water.

[0072] Specifically, the resin tank 010 is filled with resin, which can be layered. The top of the resin tank 010 is equipped with a soft water valve 020. The inlet of the soft water valve 020 can be connected to tap water, so that tap water flows into the resin tank 010 to form a water flow. The water distributor inside the resin tank 010 can guide the water flow to be evenly distributed on the cross-section of the resin tank 010, so that the water flow can be evenly contacted with the resin layer, thereby improving the efficiency and uniformity of ion exchange between the water and the resin layer. The generated soft water can flow from the first outlet to the first-stage filter element 501, and the second outlet can also directly supply soft water to the user.

[0073] Please see Figure 1 In some embodiments, the secondary filter element 502 has a wastewater outlet, and the wastewater outlet is equipped with a wastewater drain valve 0032 for controlling the opening and closing of the wastewater outlet.

[0074] It should be noted that the secondary filter element 502 will generate wastewater when filtering the first filtered water. By setting a wastewater outlet on the secondary filter element 502 and a wastewater drain valve 0032 that controls the opening and closing of the wastewater outlet, the wastewater can be discharged from the secondary filter element 502 when it is necessary to discharge the wastewater. This makes it very convenient to discharge the wastewater.
