DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0032] Nowadays, the device with the function of softening water used in households is a water softener. The soft water produced by the water softener is usually directly provided to users after only preliminary filtration. For example, the water softener is directly connected to water heating equipment such as water heaters, wall-mounted boilers, and electric water heaters to directly heat the soft water and provide hot water to users.

[0033] However, soft water has only undergone primary filtration and users cannot drink it directly. In addition, soft water still contains a lot of sodium ions. After being heated, soft water will form scale in water heating equipment such as water heaters, wall-mounted boilers, electric water heaters, and in bathroom pipes, which can easily lead to pipe blockage and a decrease in the heat exchange efficiency of the heating equipment.

[0034] To solve the above technical problems, please refer to Figure 1 , which is a soft, clean and hot single water channel system proposed in the present application. The soft, clean and hot single water channel system includes a soft water system 002, a primary filter element 501, a secondary filter element 502 and a heating system 004 which are connected in series in sequence. The primary filter element 501 is used to filter the soft water flowing from the soft water system 002 into the primary filter element 501, and the primary filter element 501 is used to output first filtered water to the secondary filter element 502, the secondary filter element 502 is used to filter the first filtered water flowing into the secondary filter element 502, and the secondary filter element 502 is used to output first pure water to the heating system 004, the heating system 004 is used to heat the first pure water flowing into the heating system 004, and the heating system 004 is used to supply hot water to users.

[0035] It can be understood that the soft water system 002 is a device that uses cation exchange resin to remove calcium and magnesium ions in water, reduce the hardness of raw water, and thus achieve the effect of softening hard water. The input port of the soft water system 002 can be connected to an external water source, for example, the input port of the soft water system 002 is connected to tap water. After the tap water is fully in contact with the resin layer in the soft water system 002 and ions are exchanged, 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 users to use, such as for users to wash fruits and vegetables. The first output port can be connected to the primary filter element 501 to allow soft water to flow into the primary filter element 501.

[0036] It should be noted that although the water after softening treatment has removed hardness ions, it may contain other impurities, such as salt residues or other dissolved substances that may be added during the softening process. The primary filter element 501 can be a polypropylene cotton filter element or an activated carbon filter element, so that the primary filter element 501 can be used to filter larger particles, sediments, etc. in the soft water. The primary filter element 501 has a first port and a second port that are interconnected. The first port is connected to the first output port, so that the primary filter element 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 primary filter element 501, and the soft water is filtered by the primary filter element 501 to form the first filtered water, and the first filtered water flows out from the second port.

[0037] In addition, the water treated by the soft water system 002 contains a relatively high level of sodium ions, and the primary filter element 501 may not be able to remove the dissolved ions. The secondary filter element 502 may be a reverse osmosis membrane or an ultrafiltration membrane, so that the secondary filter element 502 can be used to remove dissolved salts, organic matter, and microorganisms in the first filtered water. The secondary filter element 502 has a first pipe opening and a second pipe opening that are interconnected. The first pipe opening is connected to the second port, so that the secondary filter element 502 is connected in series with the primary filter element 501, and the secondary filter element 502 is located downstream of the primary filter element 501. The first filtered water can flow into the secondary filter element 502, and the first filtered water is filtered by the secondary filter element 502 to form the first pure water, which flows out from the second pipe opening.

[0038] In this embodiment, the heating system 004 has a first flow port and a second flow port that are interconnected. The first flow port is connected to the second pipe port, so that the heating system 004 is connected in series with the secondary filter element 502, and the heating system 004 is located downstream of the secondary filter element 502. The first pure water can flow into the heating system 004. The first pure water is heated by the heating system 004 to form hot water, and the hot water flows out from the second flow port for users to use. Therefore, the soft, clean and hot single water channel system can ensure that dissolved salts in the water are removed before heating, so that there will be no scale during heating, which will not affect the heating efficiency and service life of the heating system 004. At the same time, the purity of the water can be guaranteed and can be directly drunk by users.

[0039] Specifically, the soft, clean, and hot single-waterway system can further include a pure water outlet valve, which can be communicated with the second pipe orifice, so that the pure water outlet valve can be used to directly provide the first pure water for users to drink directly.

[0040] Please refer to Figure 1 , in some embodiments, the primary filter element 501 can include a pre-filter element 5011 and a post-filter element 5012. The pre-filter element 5011 is connected in series between the soft water system 002 and the secondary filter element 502. The pre-filter element 5011 is used to filter the soft water flowing from the soft water system 002 into the pre-filter element 5011, and the pre-filter element 5011 outputs the first filtered water to the secondary filter element 502. The post-filter element 5012 is connected in series between the secondary filter element 502 and the heating system 004. The post-filter element 5012 is used to filter the first pure water flowing from the secondary filter element 502 into the post-filter element 5012, and the post-filter element 5012 outputs the second pure water to the heating system 004.

[0041] It should be noted that the pre-filter element 5011 and the post-filter element 5012 can respectively handle different pollutants. For example, the pre-filter element 5011 can be a polypropylene cotton filter element, so that the pre-filter element 5011 can filter large particles, sediment and other impurities in the water. The post-filter element 5012 can be an activated carbon filter element, so that the post-filter element 5012 can remove chlorine or organic substances in the water.

[0042] The pre-filter element 5011 can have a first port and a second port. The first port is communicated with the first output port, and the second port is communicated with the first pipe orifice, so that the pre-filter element 5011 can be connected in series between the soft water system 002 and the secondary filter element 502. The soft water softened by the soft water system 002 can flow into the pre-filter element 5011. The pre-filter element 5011 can filter large particles, sediment 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.

[0043] The post-filter element 5012 can have a third port and a fourth port that are communicated with each other. The third port can be communicated with the second pipe orifice, and the fourth port can be communicated with the first flow port, so that the post-filter element 5012 can be connected in series between the secondary filter element 502 and the heating system 004. The first pure water formed after being filtered by the secondary filter element 502 can flow into the post-filter element 5012. The post-filter element 5012 can further purify the first pure water, such as adsorbing peculiar smell or intercepting possible filter element shedding substances. The post-filter element 5012 can output the second pure water, and the taste of the second pure water is better.

[0044] Please refer to Figure 1, in some embodiments, the soft water purification and heating single waterway system further includes a pure water reflux control member 0031. The first end of the pure water reflux control member 0031 is communicated with the upstream of the secondary filter element 502 at a first communication node a, and the second end of the pure water reflux control member 0031 is communicated with the downstream of the secondary filter element 502 at a second connection node. The pure water reflux control member 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.

[0045] Optionally, the first end and the second end of the pure water reflux control member 0031 are two interfaces of the pure water reflux control member 0031. The first communication node a may have two mutually communicated interfaces. The first interface of the first communication node a is communicated with the first end of the pure water reflux control member 0031, and the second interface of the first communication node a is communicated with the first pipe orifice of the secondary filter element 502, so that the first end of the pure water reflux control member 0031 is communicated with the upstream of the secondary filter element 502.

[0046] The second communication node b may have two mutually communicated interfaces. The first interface of the second communication node b is communicated with the second end of the pure water reflux control member 0031, and the second interface of the second communication node b is communicated with the second pipe orifice of the secondary filter element 502, so that the second end of the pure water reflux control member 0031 is communicated with the downstream of the secondary filter element 502. And the pure water reflux control member 0031 may be a pure water reflux check valve. The pure water reflux control member 0031 can control the unidirectional conduction from its second end to the first end. When the soft water purification and heating single waterway system is not working, the first pure water can be controlled by the pure water reflux control member 0031 to flow unidirectionally from the downstream of the secondary filter element 502 to the upstream of the secondary filter element 502, which can form a water flow to wash the dirt on the filter membrane in the secondary filter element 502, prevent the secondary filter element 502 from being blocked, and can extend the service life of the secondary filter element 502.

[0047] Please refer to Figure 1 , in some embodiments, the first end of the pure water reflux control member 0031 is communicated with the upstream of the secondary filter element 502 and the downstream of the pre-filter element 5011 at a first communication node a, and the second end of the pure water reflux control member 0031 is communicated with the downstream of the secondary filter element 502 and the upstream of the post-filter element 5012 at a second communication node b.

[0048] Specifically, the first connection point is a tee, which has three mutually connected interfaces. The first interface of the first communication node a is connected to the first end of the pure water reflux control member 0031, the second interface of the first communication node a is connected to the first pipe orifice of the secondary filter element 502, and the third interface of the first communication node a is connected to the second port of the pre-filter element 5011, such that the first end of the pure water reflux control member 0031 is connected to the pipeline between the upstream of the secondary filter element 502 and the downstream of the pre-filter element 5011, which can simplify the pipeline layout between the secondary filter element 502 and the pre-filter element 5011.

[0049] The second connection point is a tee, which has three mutually connected interfaces. The first interface of the second communication node b is connected to the second end of the pure water reflux control member 0031, the second interface of the second communication node b is connected to the second pipe orifice of the secondary filter element 502, and the third interface of the second communication node b is connected to the third port of the post-filter element 5012, such that the second end of the pure water reflux control member 0031 is connected to the pipeline between the downstream of the secondary filter element 502 and the upstream of the post-filter element 5012, which can simplify the pipeline layout between the secondary filter element 502 and the post-filter element 5012.

[0050] Please refer to Figure 1 , in some embodiments, the soft water, purification, and heating single waterway system further includes a booster pump 70, which is connected in series between the pre-filter element 5011 and the secondary filter element 502, and the booster pump 70 is located downstream of the first communication node a.

[0051] It should be noted that the soft water, purification, and heating single waterway system is sequentially connected in series with a soft water system 002, a primary filter element 501, a secondary filter element 502, and a heating system 004. The relatively large number of serially connected processing units will reduce the water pressure inside the soft water, purification, and heating single waterway system. Especially, the secondary filter element 502 is a reverse osmosis filter element, and the secondary filter element 502 requires a certain pressure to operate, resulting in a relatively high water pressure requirement for the soft water, purification, and heating single waterway system.

[0052] In this embodiment, by connecting the booster pump 70 in series between the pre-filter element 5011 and the secondary filter element 502, the booster pump 70 can increase the water pressure inside the soft water, purification, and heating single waterway system to maintain the normal operation of the soft water, purification, and heating single waterway system. And the booster pump 70 is located upstream of the secondary filter element 502, so that the booster pump 70 can boost the pressure for the secondary filter element 502 to ensure that the secondary filter element 502 can operate normally.

[0053] In addition, the boost pump 70 is located downstream of the first connecting node a, so that the boost pump 70, the pure water reflux control component 0031 and the secondary filter element 502 can form a loop. When the pure water reflux control component 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 boost 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 in the secondary filter element 502.

[0054] See also Figure 1 In some embodiments, the soft, clean and hot single water channel system also includes a filtered water outlet valve 503, which is connected in series between the pre-filter element 5011 and the secondary filter element 502. The filtered water outlet valve 503 is used to selectively connect the pre-filter element 5011 and the secondary filter element 502, and the filtered water outlet valve 503 is located upstream of the first connecting node a.

[0055] Specifically, by setting a filtered water outlet valve 503 between the pre-filter element 5011 and the secondary filter element 502, the filtered water outlet valve 503 can control the selective conduction between the pre-filter element 5011 and the secondary filter element 502, so that the entire soft, clean and hot single water system can be conveniently controlled to be opened or closed. The filtered water outlet valve 503 is set upstream of the first connecting node a, so that the filtered water outlet valve 503 can be located upstream of the pure water reflux control component 0031, so that the filtered water outlet valve 503 will not affect the pure water reflux control component 0031, so that when the filtered water outlet valve 503 is in a closed state, or when the soft, clean and hot single water system is closed, the pure water reflux control component 0031 can also control 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, so as to flush the dirt on the filter membrane in the secondary filter element 502.

[0056] See also Figure 1 In some embodiments, the soft, clean and hot single water channel system also includes a raw water quality detection component 040, which is connected in series between the pre-filter element 5011 and the secondary filter element 502. The raw water quality detection component 040 is used to detect the water quality of the first filtered water flowing into the secondary filter element 502, and the raw water quality detection component 040 is located downstream of the first connecting node a.

[0057] It is understandable that after long-term use of the soft, clean and hot single water system, the pre-filter 5011 may be damaged. By connecting the raw water quality detection component 040 in series between the pre-filter 5011 and the secondary filter 502, the raw water quality detection component 040 can detect the first filtered water flowing out of the pre-filter 5011. When a large number of large particles of impurities are detected in the first filtered water, it can indicate that the pre-filter 5011 is damaged. The raw water quality detection component 040 can issue a first alarm to remind the user that the pre-filter 5011 needs to be replaced.

[0058] In addition, a raw water quality detector 040 is disposed downstream of the first communication node a, such that the raw water quality detector 040 can be located between the first ends of the pure water reflux control member 0031. Thus, when the pure water reflux control member 0031 controls the one-way flow of the first pure water from the downstream of the secondary filter element 502 to the upstream of the secondary filter element 502, the raw water quality detector 040 can also detect the water quality of the first pure water. When the raw water quality detector 040 detects that the concentration of dissolved substances in the first pure water is relatively high, it can indicate that the secondary filter element 502 has been damaged. The raw water quality detector 040 can issue a second warning to remind the user to replace the secondary filter element 502.

[0059] Please refer to Figure 1 , in some embodiments, the soft purification, heating and single waterway system further includes a pure water flow control member 0033. The pure water flow control member 0033 is connected in series between the post-filter element 5012 and the heating system 004. The pure water flow control member 0033 is configured to make the second pure water flow unidirectionally from the post-filter element 5012 to the heating system 004.

[0060] It should be noted that the post-filter element 5012 is an activated carbon filter element. If hot water flows back into the post-filter element 5012 from the heating system 004 when the soft purification, heating and single waterway system is turned off, the activated carbon filter element may cause carbon powder to fall off or bacteria to breed due to long-term contact with hot water.

[0061] In this embodiment, by connecting the pure water flow control member 0033 in series between the post-filter element 5012 and the heating system 004, and the pure water flow control member 0033 is configured to make the second pure water flow unidirectionally from the post-filter element 5012 to the heating system 004, it is possible to prevent the hot water in the heating system 004 from flowing back into the post-filter element 5012, and prevent bacteria from breeding in the post-filter element 5012.

[0062] Please refer to Figure 1 , in some embodiments, the soft purification, heating and single waterway system further includes a hot water tank water filling valve 0041. The hot water tank water filling valve 0041 is connected in series between the pure water flow control member 0033 and the heating system 004. The hot water tank water filling valve 0041 is configured to selectively connect the pure water flow control member 0033 and the heating system 004.

[0063] In this embodiment, the heating system 004 includes a hot water tank assembly. The hot water tank assembly includes a tank body and a heating element. The tank body can be communicated with the fourth port of the post-filter 5012, so that the second pure water can flow into the tank body. Thus, the heating element can heat the second pure water. The water volume in the tank body can affect the efficiency of hot water output. By connecting the hot water tank water replenishing valve 0041 in series between the pure water flow control member 0033 and the heating system 004, and the hot water tank water replenishing valve 0041 is used to selectively communicate the pure water flow control member 0033 and the heating system 004, the water volume in the tank body can be controlled through the hot water tank water replenishing valve 0041, so as to further control the efficiency of hot water output.

[0064] Please refer to Figure 1 , in some embodiments, the soft purification and heating single waterway system further includes a pure water quality detection member 0034. The pure water quality detection member 0034 is connected in series between the post-filter 5012 and the heating system 004. The pure water quality detection member 0034 is used to detect the quality of the second pure water flowing into the heating system 004.

[0065] It can be understood that if the water quality is relatively hard, scale is likely to form in the tank body of the heating system 004, which will reduce the heating efficiency of the heating system 004. By connecting the pure water quality detection member 0034 in series between the post-filter 5012 and the heating system 004, the pure water quality detection member 0034 can detect the quality of the second pure water flowing into the heating system 004. When it is detected that the quality of the second pure water is relatively hard, the user can be reminded that the quality of the second pure water no longer meets the requirements, which can prevent scale from forming in the tank body. In addition, it can also indicate that the secondary filter element 502 may be damaged, and the user can be reminded to replace the secondary filter element 502.

[0066] Please refer to Figure 1 , in some embodiments, the soft purification and heating single waterway system further includes a pipeline machine 006. The pipeline machine 006 is communicated with the downstream of the post-filter 5012.

[0067] Specifically, the pipeline machine 006, also known as a pipeline water dispenser or a wall-mounted pipeline water dispenser, is a drinking water device specifically used in places such as families, offices, and schools. Connecting the pipeline machine 006 to the downstream of the post-filter 5012 enables the second pure water to flow to the pipeline machine 006. The pipeline machine 006 can provide 24-hour uninterrupted cold and hot water supply, so that the soft purification and heating single waterway system can meet the drinking water needs of family members at any time.

[0068] Please refer to Figure 1 , in some embodiments, the soft purification and heating single waterway system further includes a water pump 30. The water pump 30 is arranged downstream of the heating system 004.

[0069] Optionally, hot water can be stored in the tank of the heating system 004. By arranging the water pump 30 downstream of the heating system 004, the water pump 30 can suck the hot water heated by the heating system 004 for the user to use, facilitating the user's use of hot water.

[0070] Please refer to Figure 1 , in some embodiments, the soft water system 002 includes a resin tank 010 and a soft water valve 020. The soft water valve 020 is connected to the resin tank 010. The soft water valve 020 has an input port, a first output port, and a second output port. The input port is used to communicate with an external water source. The first output port is used to output soft water to the primary filter element 501. The second output port is used to supply soft water.

[0071] Specifically, resin is installed inside the resin tank 010. The resin can be arranged in layers. A soft water valve 020 is provided at the top of the resin tank 010. The input port 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 in the resin tank 010 can guide the water flow to be evenly distributed on the cross-section of the resin tank 010, enabling the water flow to evenly contact the resin layer, thereby improving the efficiency and uniformity of the ion exchange between the water and the resin layer. The generated soft water can flow from the first output port to the primary filter element 501, and the second output port can also directly supply soft water to the user.

[0072] Please refer to Figure 1 , in some embodiments, the secondary filter element 502 has a waste water port, and a waste water drain valve 0032 for controlling the opening and closing of the waste water port is provided at the waste water port.

[0073] It should be noted that waste water is generated when the secondary filter element 502 filters the first filtered water. By providing a waste water port on the secondary filter element 502 and a waste water drain valve 0032 for controlling the opening and closing of the waste water port at the waste water port, when it is necessary to discharge the waste water, the waste water drain valve 0032 can be controlled to open, so as to discharge the waste water from the secondary filter element 502, and the waste water can be discharged very conveniently.
