Description

Technical Field

[0001] This utility model relates to the field of integrated cleaning and softening machine technology, specifically providing an integrated cleaning and softening machine and its valve assembly. Background Technology

[0002] With the continuous improvement of people's living standards and the increasing emphasis on water quality, household water purifiers have become common appliances in most families. Among them, as a type of water purifier, the pre-filter is chosen by most users and installed on the main water inlet pipe of the house due to its low operating cost.

[0003] However, in many areas, the water quality is hard. Pre-filters can only remove larger particles of impurities, but cannot remove calcium and magnesium ions, making hard water unsuitable for washing clothes. Therefore, integrated water purifiers and softeners have emerged. These systems consist of a softening section and a purifying section. The purifying section includes a filter cartridge, while the softening section includes a resin tank and a softening valve connected to it. The inlet of the purifying filter cartridge is connected to the inlet pipe, and the outlet is connected to the inlet of the softening valve; in other words, the softening and purifying sections are connected in series. Water first passes through the filter cartridge, then flows into the resin tank via the softening valve. After being softened by the resin tank, the water becomes soft water with a lower concentration of calcium and magnesium ions, and finally flows out through the softening valve.

[0004] Although a water softener and softener combo provides purified water with lower calcium and magnesium ion content by connecting the softening and purification sections in series, in daily use, the filter cartridge creates resistance to water flow. The water pressure and flow rate decrease after filtration. When this filtered water flows through the resin tank of the softening section, the resistance from the ion exchange resin further reduces the flow rate of the softened water. When washing clothes in a washing machine, although the combo provides softened water, the slow flow rate results in a longer water intake time, leading to a poor user experience. In other words, the single connection of the purification and softening sections in a combo cannot meet diverse usage needs and has poor adaptability.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the single connection method of the water purification part and the water softening part in the water purifier and softener integrated machine cannot meet different usage needs and has poor adaptability.

[0007] In a first aspect, the present invention provides a valve assembly for an integrated water purifier and softener, the valve assembly including a softener valve, an inlet pipe and a first outlet pipe, the softener valve having an inlet, a softener outlet and a resin tank interface for connection with a resin tank, a first end of the inlet pipe for connection to a water source, a second end of the first outlet pipe for water discharge, the inlet being selectively connected to both the inlet pipe and the first outlet pipe, the inlet pipe and the first outlet pipe also being respectively provided with a first interface and a second interface, the first interface and the second interface being respectively used to connect to the inlet and outlet of a filter element.

[0008] In the preferred embodiment of the valve assembly of the above-mentioned integrated water purifier and softener, the valve assembly includes a three-way valve, the water inlet is connected to the third interface of the three-way valve, the first interface and the second interface of the three-way valve are respectively connected to the water inlet pipe and the first water outlet pipe, and the third interface of the three-way valve can be selectively connected to the first interface and the second interface of the three-way valve.

[0009] In the preferred embodiment of the valve assembly of the above-mentioned integrated water purifier and softener, the first and second ports of the three-way valve are respectively connected to the second end of the inlet pipe and the first end of the first outlet pipe.

[0010] In the preferred embodiment of the valve assembly of the aforementioned integrated water purifier and softener, the three-way valve, the inlet pipe, and the first outlet pipe are integrated into a single water circuit board.

[0011] In the preferred embodiment of the valve assembly of the above-mentioned integrated water purifier and softener, a second water outlet pipe is also integrated on the water circuit board. The first end of the second water outlet pipe is connected to the softened water outlet, and the second end of the second water outlet pipe, the second end of the first water outlet pipe, and the first end of the water inlet pipe are located on the same side of the water circuit board.

[0012] In the preferred embodiment of the valve assembly of the above-mentioned integrated water purifier and soft water dispenser, the third port of the three-way valve and the first end of the second water outlet pipe are oriented in the same direction, and the water inlet and the soft water outlet are oriented in the same direction; the water inlet and the soft water outlet are respectively plugged into and connected to the third port of the three-way valve and the first end of the second water outlet pipe.

[0013] In the preferred embodiment of the valve assembly of the above-mentioned integrated water purifier and softener, the resin tank interface is located on the lower side of the softener valve, and the first interface and the second interface are located on the lower side of the water circuit board.

[0014] In the preferred technical solution of the valve assembly of the above-mentioned integrated cleaning and softening machine, the first interface and the second interface are plug-in connectors.

[0015] In the preferred embodiment of the valve assembly of the above-mentioned integrated water purifier and softener, the water inlet is connected to the water inlet pipe and the first water outlet pipe. The valve assembly further includes a first valve and a second valve. The first valve is used to switch the on / off state of the water inlet and the water inlet pipe, and the second valve is used to switch the on / off state of the water inlet and the first water outlet pipe.

[0016] When the above technical solution is adopted, the valve assembly of the integrated water purifier and softener includes a softener valve, an inlet pipe and a first outlet pipe. The softener valve has an inlet, a softener outlet and a resin tank interface for connecting to the resin tank. The first end of the inlet pipe is used to connect to a water source, and the second end of the first outlet pipe is used to discharge water. The inlet can be selectively connected to the inlet pipe and the first outlet pipe. The inlet pipe and the first outlet pipe are also respectively provided with a first interface and a second interface, which are respectively used to connect to the inlet and outlet of the filter element.

[0017] When the valve assembly is installed in the water purifier and softener, and the inlet is connected to the inlet pipe but not to the first outlet pipe, the resin tank and filter element are in a split state, allowing the water to be divided into two parts. The first part of the water flows through the resin tank without flowing through the filter element, and flows out after being softened by the resin tank. The second part of the water flows through the filter element without flowing through the resin tank, and flows out after being filtered by the filter element. When the inlet is connected to the first outlet pipe but not to the inlet pipe, the resin tank and filter element are in a series state, allowing the water to first flow through the filter element, flow into the resin tank after being filtered by the filter element, and then flow out after being softened by the resin tank. When using the washing machine to wash clothes, adjust the valve assembly of the water purifier and softener so that the inlet of the softened water valve is connected to the inlet pipe but not to the first outlet pipe. In this state, the resin tank and filter cartridge are in a split-flow condition, allowing tap water to bypass the filter cartridge and directly enter the resin tank. After being softened by the resin tank, the softened water flows out from the softened water outlet of the softened water valve and is supplied to the washing machine. This eliminates the resistance of the filter cartridge to the water flow, relatively increasing the flow rate of the softened water supplied to the washing machine, shortening the water intake time, and optimizing the user experience. When the user needs to collect water for cooking, adjust the valve assembly of the water purifier and softener so that the inlet of the softened water valve is connected to the first outlet pipe but not to the inlet pipe. In this state, the resin tank and filter cartridge are in a series connection. Tap water first enters the filter cartridge, is filtered, and then flows into the resin tank. After being softened by the resin tank, it flows out from the softened water outlet of the softened water valve and is supplied to the user, thus providing the user with cleaner, softer water suitable for drinking.

[0018] By configuring the valve assembly of the integrated purifier and softener, the filter element and resin tank can switch between series and split modes, thus better adapting to different usage scenarios and optimizing the user experience.

[0019] Preferably, the valve assembly includes a three-way valve, with the inlet connected to the third port of the three-way valve, the first port and the second port of the three-way valve connected to the inlet pipe and the first outlet pipe respectively, and the third port of the three-way valve being able to selectively connect to either the first port or the second port of the three-way valve.

[0020] With this setup, the filter cartridge and resin tank of the integrated purifier and softener can be switched between series and split states by adjusting the state of the three-way valve.

[0021] Preferably, the three-way valve, the inlet pipe, and the first outlet pipe are integrated into a single water circuit board.

[0022] This setup facilitates the fixing of the three-way valve, inlet pipe, and first outlet pipe, as well as their connection to other pipelines.

[0023] Preferably, the water circuit board also integrates a second water outlet pipe, the first end of which is connected to the soft water outlet, and the second end of which is located on the same side of the water circuit board as the second end of the first water outlet pipe and the first end of the inlet pipe.

[0024] This design concentrates the connection interfaces between the valve assembly and external pipelines of the integrated water purifier and softener on one side of the water circuit board, facilitating connection with external pipelines.

[0025] Preferably, the third port of the three-way valve and the first end of the second outlet pipe are oriented in the same direction, and the inlet and soft water outlet are oriented in the same direction; the inlet and soft water outlet are respectively plugged into the third port of the three-way valve and the first end of the second outlet pipe.

[0026] With this setup, the soft water valve and the water circuit board are manufactured separately and then connected together, which facilitates the manufacturing and installation of the valve assembly.

[0027] Preferably, the resin tank interface is located on the lower side of the soft water valve, and the first interface and the second interface are located on the lower side of the water circuit board.

[0028] This setup allows for easy connection of the valve assembly of the integrated purifier and softener above the resin tank and filter element, resulting in a more compact arrangement of the valve assembly, resin tank, and filter element.

[0029] Preferably, the first interface and the second interface are plug-in connectors.

[0030] This design facilitates the installation and removal of valve components and filter elements in the integrated purifier and softener.

[0031] In a second aspect, the present invention also provides an integrated cleaning and softening machine, which includes a resin tank, a filter element, and a valve assembly of the integrated cleaning and softening machine according to any of the above technical solutions.

[0032] It should be noted that this integrated cleaning and softening machine has all the technical effects of the valve assembly of the aforementioned integrated cleaning and softening machine, which will not be repeated here. Attached Figure Description

[0035] First, those skilled in the art should understand that the embodiments described below are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0036] It should be noted that in the description of the utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Based on the problem mentioned in the background technology that the single connection method of the water purification section and the water softening section in the integrated water purifier and softener cannot meet different usage needs and has poor adaptability, this utility model provides a valve assembly for the integrated water purifier and softener, including a soft water valve, an inlet pipe and a first outlet pipe. The soft water valve has an inlet, a soft water outlet and a resin tank interface for connecting to the resin tank. The first end of the inlet pipe is used to connect to a water source, and the second end of the first outlet pipe is used to discharge water. The inlet can be selectively connected to the inlet pipe and the first outlet pipe. The inlet pipe and the first outlet pipe are also respectively provided with a first interface and a second interface, which are respectively used to connect to the inlet and outlet of the filter element.

[0039] When the valve assembly is installed in the water purifier and softener, and the inlet is connected to the inlet pipe but not to the first outlet pipe, the resin tank and filter element are in a split state, allowing the water to be divided into two parts. The first part of the water flows through the resin tank without flowing through the filter element, and flows out after being softened by the resin tank. The second part of the water flows through the filter element without flowing through the resin tank, and flows out after being filtered by the filter element. When the inlet is connected to the first outlet pipe but not to the inlet pipe, the resin tank and filter element are in a series state, allowing the water to first flow through the filter element, flow into the resin tank after being filtered by the filter element, and then flow out after being softened by the resin tank. When using the washing machine to wash clothes, adjust the valve assembly of the water purifier and softener so that the inlet of the softened water valve is connected to the inlet pipe but not to the first outlet pipe. In this state, the resin tank and filter cartridge are in a split-flow condition, allowing tap water to bypass the filter cartridge and directly enter the resin tank. After being softened by the resin tank, the softened water flows out from the softened water outlet of the softened water valve and is supplied to the washing machine. This eliminates the resistance of the filter cartridge to the water flow, relatively increasing the flow rate of the softened water supplied to the washing machine, shortening the water intake time, and optimizing the user experience. When the user needs to collect water for cooking, adjust the valve assembly of the water purifier and softener so that the inlet of the softened water valve is connected to the first outlet pipe but not to the inlet pipe. In this state, the resin tank and filter cartridge are in a series connection. Tap water first enters the filter cartridge, is filtered, and then flows into the resin tank. After being softened by the resin tank, it flows out from the softened water outlet of the softened water valve and is supplied to the user, thus providing the user with cleaner, softer water suitable for drinking. By configuring the valve assembly of the integrated purifier and softener, the filter element and resin tank can switch between series and split modes, thus better adapting to different usage scenarios and optimizing the user experience.

[0040] The following reference Figures 1 to 4 This utility model will be described in detail below. Among other things, Figure 1 This is a schematic diagram of the valve assembly of a cleanroom and soft-cleaner unit according to one embodiment of the present invention. Figure 1 ; Figure 2 This is a schematic diagram of the valve assembly of a cleanroom and soft-cleaner unit according to one embodiment of the present invention. Figure 2 ; Figure 3This is a schematic diagram of the structure of the soft water valve in the valve assembly of an integrated water purifier and softener according to an embodiment of this utility model; Figure 4 This is a schematic diagram of the water circuit board in the valve assembly of an integrated cleaning and softening machine according to an embodiment of this utility model.

[0041] like Figures 1 to 4 As shown, the valve assembly of the integrated water purifier and softener includes a softened water valve 1 and a water circuit board 2. The lower side of the softened water valve 1 has a resin tank interface 11 for connection to the resin tank, and the right side of the softened water valve 1 has an inlet 12 and a softened water outlet 13. The water circuit board 2 integrates an inlet pipe 21, a first outlet pipe 22, a second outlet pipe 23, and a three-way valve 24. The first end of the inlet pipe 21 is used to connect to a water source (such as a tap water pipe), and the second ends of the first outlet pipe 22 and the second outlet pipe 23 are used for water discharge. The first interface of the three-way valve 24 is connected to the second end of the inlet pipe 21, and the second interface of the three-way valve 24 is connected to the first end of the first outlet pipe 22. The third interface of the three-way valve 24 and the first end of the second outlet pipe 23 are both located on the left side of the water circuit board 2, and the second end of the second outlet pipe 23 is adjacent to the second end of the first outlet pipe 22 and the first end of the inlet pipe 21 on the right side of the water circuit board 2. The inlet 12 is plugged into the third port of the three-way valve 24, and the soft water outlet 13 is plugged into the first end of the second outlet pipe 23. The inlet pipe 21 is provided with a first filter element interface 211, and the first outlet pipe 22 is provided with a second filter element interface 221. The first filter element interface 211 is used to connect to the inlet of the filter element, and the second filter element interface 221 is used to connect to the outlet of the filter element. Specifically, the first filter element interface 211 and the second filter element interface 221 are located on the lower side of the water circuit board 2, and the first filter element interface 211 and the second filter element interface 221 are plug-in connectors. When the third port of the three-way valve 24 is connected to the first port but not to the second port, the inlet 12 is connected to the inlet pipe 21 but not to the first outlet pipe 22, so that the resin tank and filter element connected to the valve assembly are in a split state; when the third port of the three-way valve 24 is connected to the second port but not to the first port, the inlet 12 is connected to the first outlet pipe 22 but not to the inlet pipe 21, so that the resin tank and filter element connected to the valve assembly are in a series state. That is to say, by switching the state of the three-way valve 24, the inlet 12 is selectively connected to the inlet pipe 21 and the first outlet pipe 22, thereby switching the resin tank and filter element connected to the valve assembly between the split state and the series state.

[0042] When installed in the integrated water purifier and softener and in use, the resin tank interface 11 is connected to the resin tank, the first filter element interface 211 and the second filter element interface 221 are respectively connected to the inlet and outlet of the filter element, the first end of the water inlet pipe 21 is connected to the tap water pipe, the second end of the first water outlet pipe 22 is connected to the first external water outlet pipe, the second end of the second water outlet pipe 23 is connected to the second external water outlet pipe, and the first external water outlet pipe and the second external water outlet pipe are respectively equipped with a first water outlet valve and a second water outlet valve.

[0043] When only filtered water is needed, the three-way valve 24 is in the first state, with the third port of the three-way valve 24 connected to the first port but not to the second port, and the inlet 12 connected to the inlet pipe 21 but not to the first outlet pipe 22. This causes the resin tank and the filter element to be in a split state, with the first outlet valve open and the second outlet valve closed. Water flows into the inlet pipe 21 and into the filter element from the first filter element port 211 and the filter element inlet. After being filtered by the filter element, the water flows into the first outlet pipe 22 from the outlet of the filter element and the second filter element port 221, and finally flows from the first outlet pipe 22 to the first external outlet pipe and out.

[0044] When only softened water is needed, the three-way valve 24 is in the first state, with the third port of the three-way valve 24 connected to the first port but not to the second port, and the inlet 12 connected to the inlet pipe 21 but not to the first outlet pipe 22. This causes the resin tank and the filter element to be in a split state, with the first outlet valve closed and the second outlet valve open. Water flows into the inlet pipe 21, then through the first and third ports of the three-way valve 24, and then into the softening water valve 1 from the inlet 12. After that, it flows into the resin tank from the resin tank port 11 of the softening water valve 1. The calcium and magnesium ions in the water are replaced by sodium ions in the ion exchange resin in the resin tank, resulting in soft water with a lower concentration of calcium and magnesium ions. The soft water flows into the softening water valve 1 from the resin tank port 11 through the central pipe in the resin tank, then into the second outlet pipe 23 from the soft water outlet 13, and finally flows out from the second outlet pipe 23 to the second external outlet pipe.

[0045] When water that is both filtered and softened is needed, the three-way valve 24 is in its second state. The third port of the three-way valve 24 is connected to the second port but not to the first port. The inlet 12 is connected to the first outlet pipe 22 but not to the inlet pipe 21. This puts the resin tank and filter element connected to the valve assembly in series. The first outlet valve is closed, and the second outlet valve is open. Water flows into the inlet pipe 21 and then into the filter element through the first filter element port 211 and the filter element inlet. After being filtered by the filter element, the water flows out from the filter element outlet and the second filter element port 221. The water enters the first outlet pipe 22, then flows through the second and third ports of the three-way valve 24, and then flows into the soft water valve 1 from the inlet 12. After that, it flows into the resin tank from the resin tank port 11 of the soft water valve 1. The calcium and magnesium ions in the water are replaced by sodium ions in the ion exchange resin in the resin tank, resulting in soft water with a lower concentration of calcium and magnesium ions. The soft water flows into the soft water valve 1 from the resin tank port 11 through the central pipe in the resin tank, and then flows into the second outlet pipe 23 from the soft water outlet 13. Finally, it flows from the second outlet pipe 23 to the second external outlet pipe and flows out.

[0046] By configuring the valve assembly of the integrated purifier and softener, the filter element and resin tank can switch between series and split modes, thus better adapting to different usage scenarios and optimizing the user experience.

[0047] The inlet pipe 21, the first outlet pipe 22, the second outlet pipe 23 and the three-way valve 24 are integrated on the water circuit board 2, which facilitates the installation and fixing of the inlet pipe 21, the first outlet pipe 22, the second outlet pipe 23 and the three-way valve 24.

[0048] The second end of the second water outlet pipe 23, the second end of the first water outlet pipe 22, and the first end of the water inlet pipe 21 are arranged adjacent to each other on the right side of the water circuit plate 2. This concentrates the connection interface between the valve assembly of the water purifier and the external pipeline, making it convenient to connect to the external pipeline.

[0049] The resin tank interface 11 is located on the lower side of the soft water valve 1, and the first filter element interface 211 and the second filter element interface 221 are located on the lower side of the water circuit board 2. This allows the valve assembly of the integrated water purifier and softener to be conveniently connected above the resin tank and filter element, making the distribution of the valve assembly, resin tank and filter element more compact.

[0050] The first filter element interface 211 and the second filter element interface 221 are plug-in connectors, which facilitates the disassembly and assembly of the valve assembly and filter element of the integrated air purifier and softener.

[0051] The inlet 12 and the soft water outlet 13 are located on the right side of the soft water valve 1. The third port of the three-way valve 24 and the first end of the second outlet pipe 23 are both located on the left side of the water circuit board 2. The inlet 12 is plugged into the third port of the three-way valve 24, and the soft water outlet 13 is plugged into the first end of the second outlet pipe 23. In this way, the soft water valve 1 and the water circuit board 2 are manufactured separately and then plugged into each other, which facilitates the manufacturing and installation of the valve assembly.

[0052] It should be noted that the connection between the inlet 12 and the third interface of the three-way valve 24, and the connection between the soft water outlet 13 and the first end of the second outlet pipe 23, is only a preferred configuration. In actual applications, adjustments can be made. For example, in another configuration, the inlet 12 and the third interface of the three-way valve 24 are connected and glued together, and the soft water outlet 13 and the first end of the second outlet pipe 23 are connected and glued together. In addition, the inlet 12 and the soft water outlet 13 are located on the right side of the soft water valve 1, and the third port of the three-way valve 24 and the first end of the second outlet pipe 23 are both located on the left side of the water circuit board 2. This is also a preferred arrangement. In practical applications, adjustments can be made, such as setting the inlet 12 and the soft water outlet 13 on different sides of the soft water valve 1, setting the third port of the three-way valve 24 and the first end of the second outlet pipe 23 on different sides of the water circuit board 2, and connecting the inlet 12 and the soft water outlet 13 to the third port of the three-way valve 24 and the first end of the second outlet pipe 23 via connecting pipes. Furthermore, the first filter element interface 211 and the second filter element interface 221 are plug-in connectors. This is also a preferred arrangement. In practical applications, adjustments can be made, such as setting the first filter element interface 211 and the second filter element interface 221 as threaded connectors with external threads, and setting the filter element inlet and outlet as threaded connectors with external threads, and connecting the first filter element interface 211 and the second filter element interface 221 to the filter element inlet and outlet via nuts.

[0053] It should also be noted that the resin tank interface 11 is located below the water softener valve 1, and the first filter element interface 211 and the second filter element interface 221 are located below the water circuit board 2. This is only a preferred arrangement, and adjustments can be made in actual applications. For example, the resin tank interface 11 can be located below the water softener valve 1, and the first filter element interface 211 and the second filter element interface 221 can be located on the left side of the water circuit board 2. The first filter element interface 211 and the second filter element interface 221 are connected to the inlet and outlet of the filter element respectively through connecting pipes. In addition, the inlet pipe 21, the first outlet pipe 22, the second outlet pipe 23, and the three-way valve 24 are integrated on the water circuit board 2. This is also a preferred arrangement, and adjustments can be made in actual applications. For example, the inlet pipe 21, the first outlet pipe 22, the second outlet pipe 23, and the three-way valve 24 can be independent of each other.

[0054] In another feasible embodiment, unlike the above embodiment, the second water outlet 23 is not included, and the soft water outlet 13 is directly connected to the external water outlet pipeline.

[0055] In another feasible embodiment, unlike the above embodiment, a three-way valve 24 is not provided. Instead, a first valve and a second valve are provided. The inlet 12 is connected to the second end of the inlet pipe 21 and the first end of the first outlet pipe 22. The first valve is located on the inlet pipe 21 near the second end and is used to switch the on / off state of the inlet 12 and the inlet pipe 21. The second valve is located on the first outlet pipe 22 near the first end and is used to switch the on / off state of the inlet 12 and the first outlet pipe 22.

[0056] In addition, this utility model also provides a purification and softening machine, which includes a resin tank, a filter element, and a valve assembly of the purification and softening machine in any of the above embodiments. The resin tank interface 11 is connected to the resin tank, and the first filter element interface 211 and the second filter element interface 221 are respectively used to connect to the inlet and outlet of the filter element.

[0057] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
