[0001] The present application claims priority to the patent applications filed on June 18, 2024 with the China National Intellectual Property Office, application number 202410784845.8, entitled "Resin containing container, water softening system, control method and water softener equipment"; and filed on June 18, 2024 with the China National Intellectual Property Office, application number 202410784819.5, entitled "Water softening system, water softening system control method, device and water softener equipment". TECHNICAL FIELD

[0002] The present application relates to the technical field of water softener equipment, in particular to a resin containing container, a water softening system and a control method. BACKGROUND

[0003] Water bodies contain hardness ions such as calcium and magnesium. The effects of hardness ions on daily use include poor washing effect, reduced heat efficiency after pipe wall scaling, and irritation of the skin. A water softener can replace hardness ions in water bodies with ion exchange resin, thereby effectively removing hardness ions in water bodies and softening water quality. The replacement capacity of ion exchange resin is limited. When the resin is ineffective, high-concentration brine is used to regenerate the ineffective resin.

[0004] The existing water softening system has low utilization rate of ion exchange resin during use. In order to achieve the treatment water volume, the amount of ion exchange resin needs to be increased, resulting in a large volume of resin containing container, thereby causing the volume of the water softener to be too large.

DETAILED DESCRIPTION

[0076] For the purpose of promoting an understanding of the present application, the present application will be described with reference to the drawings. Embodiments of the present application are illustrated in the drawings. However, the present application can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.

[0077] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0078] It is to be understood that the terms "first", "second", and the like, used herein do not denote any quantity or order, but are used to distinguish one element from another. For example, a first resistor could be termed a second resistor, and similarly, a second resistor could be termed a first resistor, without departing from the scope of the application. The first resistor and the second resistor are both resistors, but they are not the same resistor.

[0079] It can be understood that "connection" in the following embodiments should be understood as "electrical connection", "communication connection" and the like if the circuits, modules, units and the like connected by the connection have transmission of electrical signals or data between each other.

[0080] It can be understood that "at least one" means one or more, and "multiple" means two or more. "At least part of an element" means part or all of the element.

[0081] As used herein, the singular forms "a", "an" and "the" can include plural forms unless the context clearly indicates otherwise. It should also be understood that the terms "comprise / comprising" or "have / having" or the like specify the presence of stated features, integers, steps, operations, components, parts or combinations thereof, but do not exclude the presence or addition of one or more other features, integers, steps, operations, components, parts or combinations thereof. At the same time, the term "and / or" used in the specification includes any and all combinations of the related listed items.

[0082] As described in the foregoing background section, the volume of the resin containing container in the existing soft water system occupies a large area. In the application scenario where the amount of ion exchange resin needs to be increased to improve the soft water treatment capacity of the soft water system, the volume of the resin containing container will be further expanded, resulting in the size of the soft water machine device being affected. In the existing soft water system, a resin containing container as shown in FIG. 1 is usually used. The overall tank of the resin containing container is arranged in a U shape. Water flows from the top down from the two end water inlets of the U-shaped resin containing container and flows out from the center pipe, so that the ion exchange resin arranged in the U-shaped pipe is in contact with the water body, and the hardness ions are replaced.

[0083] The resin containing container shown in FIG. 1 further includes an upper water distributor and a lower water distributor. The upper water distributor is used to provide a certain flow of water body for the two end water inlets of the resin containing container. The lower water distributor is used to directly provide a certain flow of water body for the center pipe. Obviously, the resin containing container shown in FIG. 1 occupies a large size in the longitudinal space, and since the structure of the resin containing container is relatively fixed, in the application requirement of increasing the contact area of the resin containing container and the water body, only the longitudinal space can be expanded to increase the contact area of the resin containing container and the water body.

[0084] The present application provides a resin containing container, which can effectively solve the problem of the large size of the resin containing container in the soft water system, and can flexibly extend the resin flow channel inside the resin containing container, fully expand the contact area of the ion exchange resin and the water body, and effectively improve the soft water capacity of the soft water system and the regeneration efficiency of the ion exchange resin.

[0085] As shown in FIG. 2, a resin accommodating container applied to a soft water system is provided, including a softening cavity 120, wherein the liquid flow channel of the softening cavity 120 is used to store ion exchange resin, and the total length of the liquid flow channel in the softening cavity in the transverse direction is greater than the total length of the liquid flow channel in the longitudinal direction. Wherein the total length of the liquid flow channel in the softening cavity in the transverse direction is the sum of the lengths of the liquid flow channels arranged in the transverse direction. The total length of the liquid flow channel in the longitudinal direction is the sum of the lengths of the liquid flow channels arranged in the longitudinal direction.

[0086] Specifically, as shown in the drawings, the tank body of the resin accommodating container in the embodiment can be a single-layer tank body arranged horizontally (also referred to as horizontally placed). Since the tank body is horizontally placed, the overall machine corresponding to the tank body of the resin accommodating container does not occupy space in the height direction, and at the same time in the length direction, the liquid flow channel can extend in the two side directions, so the resin accommodating container in the embodiment is also controllable in the transverse space.

[0087] In some specific embodiments, considering reducing the length of the transverse space occupied by the overall machine, the tank body of the resin accommodating container can also be arranged as a communicating double-layer or multi-layer tank body, so that the overall machine structure is more compact. When the tank body is a communicating double-layer or multi-layer tank body, the water flow direction at the connection of the liquid flow channels in each layer is local vertical flow, but the water flow direction of the main flow channel is still horizontal flow.

[0088] In actual application, the liquid flow channel arranged in the longitudinal direction in the embodiment is usually a bending part of the liquid flow channel, and only exists when the softening cavity 120 includes multiple liquid flow channels. If the softening cavity 120 includes only one liquid flow channel, the liquid flow channel will be arranged in the transverse direction, and the longitudinal total length is 0.

[0089] Specifically, the liquid flow channel of the softening cavity 120 is used to store ion exchange resin, and the liquid moves in the horizontal direction through ion exchange in the softening cavity 120.

[0090] Specifically, a large amount of ion exchange resin is placed in the softening cavity 120 in the embodiment, and the ion exchange resin can be used to replace the hardness ions in the water body, so as to remove the hardness ions in the water body and obtain soft water after softening the water quality. When the ion exchange resin is invalid, high-concentration salt water can be used to regenerate the resin, and by means of the ion concentration advantage, the sodium ions in the salt water are used to exchange the hardness ions such as Ca 2+ , Mg 2+ , etc. on the surface or in the pipeline of the resin.

[0091] The ion exchange part of the softening cavity 120 in the embodiment refers to the part of the tank body arranged transversely. Specifically, the transverse arrangement in the embodiment refers to the arrangement parallel to the ground. The longitudinal arrangement in the embodiment refers to the arrangement perpendicular to the ground. It should be noted that, in the embodiment, whether the liquid flow channel is arranged transversely or longitudinally, the interior part includes ion exchange resin. The ion exchange part in the embodiment specifically refers to the transversely arranged softening cavity 120, and is not limited to the transversely arranged softening cavity 120 for realizing hardness ion replacement.

[0092] In actual application, the resin containing container provided in the embodiment is arranged transversely in the soft water system. The water body in the embodiment is affected by water pressure and flows in the softening cavity 120 in a direction corresponding to the current operation mode of the soft water system. Since the ion exchange part of the softening cavity 120 in the embodiment is arranged transversely, the water body flows horizontally when passing through the ion exchange part of the softening cavity 120. The horizontal direction in the embodiment refers to the direction parallel to the ground.

[0093] In specific embodiments, the water body flows through the softening cavity 120 in the embodiment at a certain flow rate and temperature, so that the water body is more fully contacted with the ion exchange resin in the softening cavity 120, so as to fully utilize the hardness ion replacement capacity of the ion exchange resin.

[0094] In summary, the resin containing container provided in the embodiment adopts the softening cavity with transverse design, so that the softening cavity occupies less longitudinal space in the overall soft water system, and does not need to be provided with a water outlet structure such as the central pipe in FIG. 1, further reducing the space occupied by the resin containing container, which is beneficial to the miniaturization design of the soft water system.

[0095] In one embodiment, as shown in FIG. 2, the resin containing container in the embodiment includes a liquid inlet cavity 110, a softening cavity 120, and a liquid outlet cavity 130. The liquid inlet cavity 110 and the softening cavity 120 are separated by a first water distribution member 140, and the softening cavity 120 and the liquid outlet cavity 130 are separated by a second water distribution member 150. Specifically, the liquid inlet cavity 110 and the liquid outlet cavity 130 occupy 0.3%-5% of the space of the resin containing container, and the softening cavity 120 occupies 95%-99.7% of the space of the resin containing container.

[0096] Specifically, the tank body part of the resin containing container is divided into three cavities by the first water distributing member 140 and the second water distributing member 150, wherein the inlet liquid cavity 110 and the outlet liquid cavity 130 each have an opening for connecting the water pipeline in the water softening system. In actual application, the water flow direction can be from the opening of the inlet liquid cavity 110 to the opening of the outlet liquid cavity 130, or from the opening of the outlet liquid cavity 130 to the opening of the inlet liquid cavity 110. It should be noted that the water flow direction is affected by water pressure, and the cavity names in the embodiment do not limit the water flow direction.

[0097] In specific embodiments, the inlet liquid cavity 110 includes an inlet port 111, and the outlet liquid cavity 130 includes an outlet port 131. The liquid flow direction in the softening cavity 120 is different when the water softening system is in different modes. For example, when the water softening system is in the water production mode, the water enters from the inlet port 111, flows along the inlet liquid cavity 110 to the outlet liquid cavity 130, and then flows out from the outlet port 131. When the water softening system is in the backwashing mode or the regeneration mode, the water enters from the outlet port 131, flows along the outlet liquid cavity 130 to the inlet liquid cavity 110, and then flows out from the inlet port 111.

[0098] Specifically, the hole diameter of the first water distributing member 140 and the second water distributing member 150 is smaller than the minimum particle size of the ion exchange resin, so that the ion exchange resin can be filled in the softening cavity 120 without leakage. The minimum particle size of the ion exchange resin is not limited in the embodiment and can be determined according to the actual application scene. In specific embodiments, the material of the first water distributing member 140 and the second water distributing member 150 can be a hard material or a mesh, and the material of the first water distributing member 140 and the second water distributing member 150 is not limited in the embodiment. The first water distributing member 140 and the second water distributing member 150 can make the water fully contact with the ion exchange resin and fix the ion exchange resin in the softening cavity 120, so that the ion exchange resin will not be dispersed in the tank body due to the water flow.

[0099] In specific embodiments, the first water distributing member 140 and the second water distributing member 150 can make the water uniformly contact with the ion exchange resin stored in the softening cavity, and the two water distributing members together can limit the ion exchange resin in the softening cavity to ensure that the hardness ion exchange reaction occurs in the softening cavity, which is more conducive to controlling the contact area of the water with the ion exchange resin during the ion exchange process. The first water distributing member 140 and the second water distributing member 150 can be injection molded parts with mesh, high-strength nylon mesh, or PP mesh, and the specific structure type of the first water distributing member 140 and the second water distributing member 150 is not limited in the embodiment.

[0100] The resin containing container provided by the embodiment can separate the liquid inlet cavity, the softening cavity and the liquid outlet cavity based on the first water distribution member and the second water distribution member, so that the water body can stay in the softening cavity for a sufficient time, and the contact area between the ion exchange resin and the water body is greatly increased. When the soft water system is in the water production mode, the resin containing container can better provide the water softening capacity, and when the soft water system is in the regeneration mode, the regeneration efficiency of the ion exchange resin in the resin containing container will be greatly improved. In the embodiment, the water body only flows in the softening cavity under the action of water pressure, and there are fewer residual solid salt particles in the ion exchange resin, which helps to improve the regeneration effect of the ion exchange resin.

[0101] In one embodiment, as shown in FIGS. 2 and 3, the softening cavity 120 includes at least one liquid flow channel, and the liquid flow channel is arranged transversely in the softening cavity 120. Specifically, as shown in FIG. 2, the softening cavity 120 can include only one liquid flow channel. As shown in FIG. 3, the softening cavity 120 can also include two liquid flow channels, and the softening cavity 120 in FIG. 3 includes a first liquid flow channel 121 and a second liquid flow channel 122.

[0102] The effective flow channel length of the liquid flow channel is 3-85 times the effective diameter of the liquid flow channel, wherein the effective flow channel length is the liquid flow distance between the first water distribution member 140 and the second water distribution member 150, and the effective diameter is the distance between the longest two ends of the cross section of the liquid flow channel.

[0103] In the embodiment, the effective flow channel length can be the total length of the ion exchange resin filled in the liquid flow channel. As shown in FIG. 1, the effective flow channel length is the straight-line distance between the first water distribution member 140 and the second water distribution member 150. As shown in FIG. 2, the effective flow channel length is the moving distance of the water body from the first water distribution member 140 to the second water distribution member 150 in the softening cavity 120.

[0104] The effective diameter is the distance between the longest two ends of the cross section of a single liquid flow channel. For example, if the cross section of the liquid flow channel is irregular, the distance between the longest two ends of the irregular shape needs to be obtained as the effective diameter of the liquid flow channel.

[0105] In actual application, the shape of the liquid flow channel can be designed according to the needs of the actual application scene. For example, the cross section of the liquid flow channel can be circular, semicircular, square, triangular or trapezoidal, and the embodiment does not limit the specific shape of the cross section of the liquid flow channel. Preferably, the shape of the cross section of the liquid flow channel is circular or square to maximize the contact area between the ion exchange resin and the water body.

[0106] Since the softening cavity 120 in the embodiment is horizontally arranged as a whole, a proper ratio of the length of the liquid flow channel to the diameter of the liquid flow channel is required to enable the water body to flow in the liquid flow channel at a stable flow rate under the action of water pressure. In the embodiment, the minimum ratio of the effective length of the liquid flow channel to the effective diameter of the liquid flow channel is 3:1, and the maximum ratio is 85:1. The embodiment does not limit the specific values of the effective length of the liquid flow channel and the effective diameter of the liquid flow channel, and the values can be adaptively configured according to the actual application scenario.

[0107] In one embodiment, as shown in FIGS. 3, 4 and 5, if the cross-sectional shape of the liquid flow channel is square, the resin containing container can further include n-1 partition pieces 160, where n is a positive integer greater than or equal to 2.

[0108] The partition pieces 160 are arranged inside the tank of the resin containing container, and are used to divide the softening cavity 120 into n liquid flow channels. Adjacent two partition pieces 160 are arranged on different sides inside the tank, so that the liquid moving directions in adjacent two liquid flow channels are different.

[0109] In specific embodiments, the embodiment can divide the softening cavity 120 into multiple liquid flow channels by arranging the partition pieces 160 inside the tank inside the softening cavity 120. As shown in FIG. 3, when one partition piece 160 is arranged, the softening cavity 120 is divided into a first liquid flow channel 121 and a second liquid flow channel 122. As shown in FIG. 4, when two partition pieces 160 are arranged, the softening cavity 120 is divided into three liquid flow channels. As shown in FIG. 5, when three partition pieces 160 are arranged, the softening cavity 120 is divided into four liquid flow channels.

[0110] In actual application, adjacent two partition pieces 160 can be arranged opposite to each other on different sides of the tank, so that the liquid moving directions of the water body in adjacent two liquid flow channels are completely opposite.

[0111] The embodiment can effectively prolong the effective length of the liquid flow channel in the softening cavity 120 by arranging multiple partition pieces 160. Preferably, the embodiment can realize a resin containing container occupying a smaller horizontal space by adding partition pieces 160 in the softening cavity 120, appropriately expand in the vertical space, and multiply prolong the effective length of the liquid flow channel, thereby greatly improving the softening performance of the resin containing container.

[0112] It should be noted that the resin containing container in the embodiment divides multiple liquid flow channels by arranging partition pieces only in the case that the liquid flow channel is square.

[0113] In one embodiment, as shown in FIGS. 6a, 6b and 6c, the tank body of the resin containing container includes n-1 bending portions, where n is a positive integer greater than or equal to 2.

[0114] The bending portions form n liquid flow channels inside the softening cavity 120, and the moving directions of the liquid in adjacent two liquid flow channels are different.

[0115] Specifically, the tank body of the resin containing container can be designed as one-piece, and by welding, bonding or bonding treatment of multiple tank bodies of the same shape, a softening cavity 120 with multiple liquid flow channels can be formed.

[0116] Specifically, if the resin containing container in the embodiment is designed as one-piece, and the multiple liquid flow channels are divided by the bending portions, the shape of the cross section of the liquid flow channel can be any one of a square or a circle.

[0117] In one embodiment, the bending portion is circular or square. For example, as shown in FIGS. 7a, 7b and 7c, the bending portion of the resin containing container can also be square.

[0118] In actual application, the specific shape of the bending portion can be determined according to the shape of the tank body used in the one-piece forming process of the liquid flow channel. For example, if the cross-sectional shape of the liquid flow channel is square, the bending portion is also square. If the cross-sectional shape of the liquid flow channel is circular, the bending portion is circular.

[0119] In one embodiment, the contact portions of the first water distribution member 140, the second water distribution member 150 and the partition member 160 with the tank body of the resin containing container are all sealed.

[0120] Specifically, the sealing method can be glue sealing, welding sealing, sealing ring sealing, etc. In some feasible embodiments, the second water distribution member 150, the first water distribution member 140 and the partition member 160 can also be integrally formed with the tank body of the resin containing container to seal the contact portions.

[0121] Specifically, the sealing of the first water distribution member 140, the second water distribution member 150 and the partition member 160 can fix the ion exchange resin stored in the softening cavity 120, and ensure that the water moves uniformly in the softening cavity 120 and fully contacts the ion exchange resin.

[0122] In one embodiment, when the softening cavity 120 includes at least two liquid flow channels, the cross-sectional shape of the liquid flow channels is the same.

[0123] Specifically, the softening cavity 120 in the embodiment includes a plurality of liquid flow channels, and the cross-sectional shape of each liquid flow channel is the same. To ensure the stability of the flow direction of the water body in the softening cavity 120 and ensure the uniform and sufficient contact between the water body and the ion exchange resin, the space size occupied by the ion exchange part of the plurality of liquid flow channels can be kept the same in the specific implementation process.

[0124] In one of the embodiments, when the softening cavity 120 includes at least two liquid flow channels, the liquid moving direction at the connection between the two adjacent liquid flow channels is irregular.

[0125] Specifically, for the softening cavity 120 with a square bending part or the softening cavity 120 with the added partition 160, the liquid flow direction at the connection between the two adjacent liquid flow channels changes twice by 90°, and for the softening cavity 120 with a circular arc bending part, the liquid moving direction changes by 180° in the rotating direction.

[0126] In the specific embodiment, the liquid moving direction at the connection between the two adjacent liquid flow channels can be determined according to the specific structure of the push flow type softening cavity 120 in the actual application scene, which is not limited here. It can be understood that the irregular direction in the embodiment refers to the change of the liquid moving direction according to the change of the structure, and does not mean that the liquid will flow randomly.

[0127] In summary, the embodiment provides a resin containing container, which can not only effectively control the occupation of the resin containing container in the horizontal space, but also further control the occupation of the resin containing container in the vertical space. The embodiment can provide a resin containing container including a plurality of liquid flow channels, which greatly expands the effective length of the ion exchange resin and effectively improves the softening performance of the resin containing container for the water body. After being applied in a water softening system, the contact area between the ion exchange resin and the high-concentration brine increases, which can more favorably regenerate the ion exchange resin, and effectively improves the utilization efficiency of the regenerated salt.

[0128] In addition, as shown in FIG. 8, the embodiment also provides a water softening system, which includes a pre-filter 801, a resin containing container 802, a salt liquid generating device 803, a water tank 804, a controller, a first switch 805, a second switch 806, a third switch 807, a fourth switch 808, a fifth switch 809, a sixth switch 810, a seventh switch 811, a first water pump 812, a second water pump 813, an eighth switch 814, and a heating module 815.

[0129] The resin accommodating container 802 in the embodiment is laid in a horizontal manner, i.e. inside the tank body, with the water flow direction parallel to the ground and flowing horizontally. Compared with the conventional water softener with the water flow direction perpendicular to the ground, the resin accommodating container 802 in the embodiment is more flat and does not occupy the height space, thereby effectively reducing the size of the water softener device.

[0130] In addition, the resin accommodating container 802 with the multi-layer resin flow channel structure in the embodiment can effectively increase the effective contact distance between the water and the resin, thereby improving the softening performance of the water softening system, effectively improving the regeneration ability of the ion exchange resin for the high-concentration salt solution, and effectively improving the utilization rate of the solid salt.

[0131] In the embodiment, the resin accommodating container 802 includes a resin flow channel for loading the ion exchange resin, the total length of the resin flow channel in the horizontal direction is greater than the total length of the resin flow channel in the vertical direction, and the water flow direction in the resin accommodating container is parallel to the flow direction of the resin flow channel.

[0132] The salt solution generating device 803 includes a salt dissolving flow channel for generating the regeneration salt solution in real time, and the water flow direction in the salt solution generating device 803 is parallel to the flow direction of the salt dissolving flow channel.

[0133] The water path switch is arranged at the water path connection of the water softening system, the resin accommodating container 802 is connected to the salt solution generating device through the water path switch, the power assembly is arranged at both ends of the salt solution generating device, and the power assembly and the water path switch are connected to the controller.

[0134] The controller is used to control the on-off state of the corresponding water path switch and the start-stop state of the corresponding power assembly according to the system control instruction, so that the water body flows in the direction corresponding to the to-be-implemented working mode.

[0135] In specific embodiments, the resin flow channel in the resin accommodating container 802 in the embodiment is used to load the ion exchange resin, and includes a water inlet, a water outlet, and a screen arranged at the water inlet and the water outlet of the resin accommodating container 802. It should be noted that the resin accommodating container 802 in the embodiment is laid in a horizontal manner, and therefore the total length of the resin flow channel in the horizontal direction is greater than the total length of the resin flow channel in the vertical direction. The total length of the flow channel in the horizontal direction is the total length of the flow channel in the horizontal direction, and the total length of the flow channel in the vertical direction is the total length of the flow channel in the vertical direction. In the embodiment, the horizontal direction is the direction parallel to the ground, and the vertical direction is the direction perpendicular to the ground.

[0136] The water flow direction in the resin accommodating container is parallel to the flow direction of the resin flow channel, that is, inside the tank body, the water flow direction is parallel to the ground and flows horizontally. The placement mode of the resin accommodating container 802 in this embodiment is more flat than the conventional soft water machine water flow direction and the ground vertical placement mode, which does not occupy the height space, so as to effectively reduce the size of the soft water machine equipment.

[0137] In addition, in the first embodiment of the resin accommodating container 802 of the present application, a resin flow channel is included, so that the tank flow is a single linear flow channel. In the second embodiment of the resin accommodating container 802 of the present application, multiple layers of resin flow channels are included, and the flow channels are separated by a partition plate. In the third embodiment of the resin accommodating container 802 of the present application, the resin accommodating container 802 can also be directly separated by bending and splicing the tank body. In a more preferred embodiment, the resin accommodating container 802 with a multi-layer resin flow channel structure can effectively increase the effective contact distance of water and resin, thereby improving the softening performance of the soft water system.

[0138] Since the resin flow channel of the resin accommodating container 802 in this embodiment is horizontally arranged as a whole, a suitable ratio of flow channel length and flow channel diameter needs to be set to enable the water body to flow in the resin flow channel at a stable flow rate under the action of water pressure. In this embodiment, the minimum ratio of the effective flow channel length of the resin flow channel to the effective diameter of the resin flow channel is 3:1, and the maximum ratio is 85:1. The specific values of the effective flow channel length and the effective diameter of the resin flow channel are not limited in this embodiment and can be adaptively configured according to the actual application scenario. It should be noted that the effective flow channel length of the resin flow channel refers to the total length of the flow channel loaded with ion exchange resin. The effective diameter of the resin flow channel is the connecting distance of the longest two ends of the cross section of the resin flow channel.

[0139] The salt solution generating device 803 in this embodiment is used to load solid salt, and the filtered water in the mixing water tank 804 can form high-concentration salt solution. In this embodiment, the salt concentration of the salted water can be controlled by adjusting the water flow into the salt solution generating device 803 and adjusting the length of the salt dissolving channel inside the salt solution generating device 803. The length of the salt dissolving channel of the salt solution generating device 803 in this embodiment can be a single layer flow channel or multiple layers of flow channels, and the specific structure of the salt solution generating device 803 is not limited in this embodiment. In a more preferred embodiment, by setting different numbers of partition plates inside the salt solution generating device 803, the length of the salt dissolving flow channel can be effectively lengthened in a limited space, the contact time of water and salt is increased, and the salt concentration of the generated salt solution is improved. The water tank 804 in this embodiment is used to store the filtered water filtered by the pre-filter and is used in the corresponding working mode.

[0140] In specific embodiments, the power assembly is arranged at both ends of the brine generating device. The brine generating device 803 in this embodiment adopts an instant brine generating mode. The driving force can be provided by the power assembly under the control of the controller to control the flow rate and flow of the water in the brine generating device 803, thereby stably achieving high-precision brine concentration control, effectively improving the utilization rate of brine, and improving the regeneration efficiency for resin regeneration.

[0141] The waterway switch in this embodiment is used to realize waterway switching control in various working modes, so that the water flows in a specified direction, thereby completing processes such as softening output processing of the water, backwashing processing of the resin containing container 802, and regeneration processing of the resin containing container 802.

[0142] Specifically, the controller in this embodiment can be a single-chip microcomputer, a micro processing unit, or a central processing unit, and the specific type of the controller is not limited in this embodiment and can be adaptively configured according to actual application scenarios. The system control instruction is an operation instruction generated by the water softener device for the working mode to be implemented. The system control instruction can be automatically generated following the system operation, or can be generated according to user operation. For example, if the system control instruction is used to implement the soft water production mode, the system control instruction needs to be automatically generated according to the user operation instruction. If the system control instruction is used to implement the salted resin regeneration mode, the system control instruction can be automatically generated according to the corresponding system time interval.

[0143] In summary, the soft water system provided in this embodiment can effectively reduce the space occupied by each component in the soft water system by arranging the resin containing container and the brine generating device in a horizontal manner, thereby making the body of the water softener device more flat, effectively reducing the volume of the water softener device, and facilitating the installation of the water softener device in other electrical devices. Secondly, the soft water system in this embodiment realizes the softening of the water, the backwashing and regeneration of the resin containing container through a small number of switch components and water pumps, proposes a new waterway design, effectively improves the utilization rate of ion exchange resin and the utilization rate of solid salt, and reduces the waste of solid salt. The soft water system proposed in this embodiment is not affected by the water inlet pressure, and the overall performance can always be maintained at the optimal value, effectively improving the stability of the regeneration brine concentration control and the soft water effect.

[0144] In specific embodiments, as shown in FIG. 9, a soft water system is provided, which includes a pre-filter 801, a resin containing container 802, a brine generating device 803, a water tank 804, a controller, a first switch component 805, a second switch component 806, a third switch component 807, a fourth switch component 808, a fifth switch component 809, a sixth switch component 810, a seventh switch component 811, a first water pump 812, and a second water pump 813.

[0145] Specifically, the water inlet of the pre-filter 801 is connected to the water inlet of the soft water system, the water outlet of the pre-filter 801 is connected to the water inlet of the resin containing container 802 through the first switch 805, the water outlet of the resin containing container 802 is connected to the water outlet of the soft water system through the second switch 806. Among them, the water inlet of the soft water system is used to access the raw water body, and in actual application, the raw water body is usually tap water, and the type of the raw water body is not limited in the embodiment. The water outlet of the soft water system is used to output the target water body, which is the soft water after filtration and softening treatment.

[0146] The water outlet of the pre-filter 801 is connected to the water outlet of the resin containing container 802 through the third switch 807, and the water inlet of the resin containing container 802 is connected to the sewage outlet of the soft water system through the fourth switch 808. Among them, the sewage outlet of the soft water system is used to output the sewage water body generated in the process of cleaning and regenerating the resin containing container 802, and the soft water system in the embodiment discharges waste water through the water inlet of the resin containing container 802 when cleaning and regenerating the resin containing container 802.

[0147] The water outlet of the pre-filter 801 is connected to the water inlet of the water tank 804 through the fifth switch 809, the first water outlet of the water tank 804 is connected to the water inlet of the brine generating device 803 through the first water pump 812, and the water outlet of the brine generating device 803 is connected to the water outlet of the resin containing container 802 through the sixth switch 810, the second water pump 813 and the seventh switch 811 in turn. The second water outlet of the water tank 804 is connected to the water outlet of the resin containing container 802 through the sixth switch 810, the second water pump 813 and the seventh switch 811 in turn. Among them, the water tank 804 in the embodiment includes a first water outlet and a second water outlet, and the water in the water tank 804 flows out through the corresponding water outlet under different regeneration and cleaning conditions.

[0148] The controller is connected to the first switch 805, the second switch 806, the third switch 807, the fourth switch 808, the fifth switch 809, the sixth switch 810, the seventh switch 811, the first water pump 812 and the second water pump 813 respectively, and the controller is used to control the switch state of the corresponding switch and the start-stop state of the corresponding water pump according to the system control instruction, so that the water body flows in the direction corresponding to the to-be-implemented working mode.

[0149] Specifically, the pre-filter in the embodiment is used to filter large particles in the raw water body, such as sand, hair, etc., so as to preliminarily intercept the water entering the soft water system and ensure the softening efficiency of the soft water system.

[0150] In specific embodiments, the first switch 805, the second switch 806, the third switch 807, the fourth switch 808, and the fifth switch 809 are all electromagnetic valve switches, the sixth switch 810 is a one-bit two-way electromagnetic valve, and the seventh switch 811 is a check valve.

[0151] It should be noted that the specific form of the switch valve in the present embodiment is not limited, and can be configured according to the needs of the actual application scene. For example, the first switch 805 and the third switch 807 can be the same one-bit two-way electromagnetic valve, the first switch 805 and the fifth switch 809 can be the same one-bit two-way electromagnetic valve, and the third switch 807 and the fifth switch 809 can also be the same one-bit two-way electromagnetic valve. In a feasible embodiment, the first switch 805, the third switch 807, and the fifth switch 809 can also be the same one-bit three-way electromagnetic valve. The three water outlets of the one-bit three-way electromagnetic valve are respectively connected to the water inlet, the water outlet of the resin containing container 802, and the water inlet of the water tank 804.

[0152] In an embodiment, as shown in FIG. 9, the resin containing container 802 includes at least one resin flow channel, and the resin flow channel is arranged transversely in the resin containing container.

[0153] In specific embodiments, the resin containing container 802 in the present embodiment is placed in a horizontal manner, and the resin containing container 802 can adopt a structure including only one resin flow channel, or a structure including multiple layers of resin flow channels. It should be noted that the length of a single layer of resin flow channels in the resin containing container 802 with a multi-layer resin flow channel structure is less than the length of a single layer of resin flow channels in the resin containing container 802 with a single-layer resin flow channel structure.

[0154] The present embodiment can separate the resin containing container 802 flow channel by setting a spacing plate, thereby realizing a longer resin flow channel in a fixed tank size, further improving the exchange rate of resin and hardness ions in the water body, and effectively improving the softening capacity of the water softening system to the water body.

[0155] In specific embodiments, the working modes to be implemented include at least a first working mode, a second working mode, a third working mode, and a fourth working mode. The first working mode corresponds to the water production mode of the water softening system, the second working mode corresponds to the backwashing mode of the water softening system, the third working mode corresponds to the salt dissolution regeneration mode of the water softening system, and the fourth working mode corresponds to the slow washing mode of the water softening system. It should be noted that the naming of each working mode in the present embodiment does not limit the function in the corresponding working mode, and is only used to illustrate the functions that can be realized in the corresponding working mode. The working modes are described in detail below.

[0156] In one embodiment, if the system control instruction is used to implement the first working mode, the controller controls the corresponding waterway switch to be in the open state, so that the water body flows into the resin containing container in the forward direction, and the target water body is obtained through ion exchange resin softening treatment.

[0157] As shown in FIG. 10, if the system control instruction is used to implement the first working mode, the controller controls the first switch 805 and the second switch 806 to be in the open state, controls other switches to be in the closed state, and controls all water pumps to be in the stopped state, so that the water body flows from the water inlet of the soft water system to the water outlet of the soft water system in sequence through the pre-filter 801, the first switch 805, the water inlet of the resin containing container 802, the water outlet of the resin containing container 802, and the second switch 806.

[0158] Specifically, the first working mode in the embodiment is a target water body water production mode, which is used to generate the target water body and output the target water body through the water outlet of the soft water system.

[0159] In specific embodiments, the principle of implementing the first working mode in the embodiment is that the raw water body is first subjected to preliminary purification through the pre-filter 801 to obtain filtered water body. At this time, the controller controls the first switch 805 and the second switch 806 to be in the open state, and controls other switches to be in the closed state, so that the filtered water body subjected to preliminary purification flows into the resin containing container 802 from the water inlet of the resin containing container 802 along direction 1, flows in the horizontal direction along the resin flow channel in the tank body, the ion exchange resin sufficiently softens the water body, and the softened water body is discharged from the water outlet of the resin containing container 802 along direction 2, flows out to the water outlet of the soft water system through the second switch 806.

[0160] In one embodiment, if the system control instruction is used to implement the second working mode, the controller controls the corresponding waterway switch to be in the open state, so that the water body flows into the resin containing container in the reverse direction to backwash the resin containing container.

[0161] As shown in FIG. 11, if the system control instruction is used to implement the second working mode, the controller controls the third switch 807 and the fourth switch 808 to be in the open state, controls other switches to be in the closed state, and controls all water pumps to be in the stopped state, so that the water body flows from the water inlet of the soft water system to the sewage outlet of the soft water system in sequence through the pre-filter 801, the third switch 807, the water outlet of the resin containing container 802, the water inlet of the resin containing container 802, and the fourth switch 808.

[0162] Specifically, the second working mode is a resin containing container 802 backwashing mode, using filtered water filtered by the pre-filter 801 to backwash the resin containing container 802, and a certain flow of filtered water is introduced in the opposite direction to the water production direction, so that the ion exchange resin in the resin containing container 802 is puffed up, and at the same time, the pollutants intercepted by the resin particles are carried out by the water flow to achieve the cleaning of the resin containing container 802.

[0163] In a specific embodiment, the principle of realizing the second working mode in the embodiment is that the controller controls the third switch 807 and the fourth switch 808 to be opened, so that the filtered water purified by the pre-filter 801 flows into the resin containing container 802 from the water outlet of the resin containing container 802 along direction 3, and then flows out of the resin containing container 802 from the water inlet of the resin containing container 802 along direction 4, and then flows out of the resin containing container 802 through the fourth switch 808 to the wastewater outlet of the water softening system, and the wastewater is discharged through the wastewater outlet of the water softening system.

[0164] In one embodiment, if the system control instruction is used to realize the third working mode, the controller controls the corresponding waterway switch to be in an open state and controls the corresponding power assembly to be in a started state, so that the water flows into the salt solution generating device according to a preset flow rate, and then controls the regenerated salt solution generated by the salt solution generating device at that moment to flow into the resin containing container in a reverse direction according to a preset flow rate, so as to regenerate the ion exchange resin in the resin containing container.

[0165] As shown in FIG. 12, if the system control instruction is used to realize the third working mode, the controller controls the fourth switch 808, the fifth switch 809, the sixth switch 810 and the seventh switch 811 to be in an open state, controls other switches to be in a closed state, and controls the first water pump 812 and the second water pump 813 to be in a started state, so that the water flows from the water inlet of the water softening system to the wastewater outlet of the water softening system through the pre-filter 801, the fifth switch 809, the water inlet of the water tank 804, the first water outlet of the water tank 804, the first water pump 812, the water inlet of the salt solution generating device 803, the water outlet of the salt solution generating device 803, the sixth switch 810, the second water pump 813, the seventh switch 811, the water outlet of the resin containing container 802, the water inlet of the resin containing container 802 and the fourth switch 808 in sequence.

[0166] Specifically, the third working mode is a salt absorption regeneration mode, in which high-concentration salt water is injected in the opposite direction to the water production direction, so that the failed ion exchange resin is regenerated to restore the softening capacity. In the third working mode, the water softening system mainly includes two control steps of generating salt water and injecting salt water.

[0167] In the control step of generating brine, the control valve controls the fifth switch 809 to enter the open state, so that the filtered water flows into the water tank 804 and continuously accumulates in the water tank 804, and when the water storage in the water tank 804 reaches a certain amount, the control valve controls the first water pump 812 to start, and a certain flow of filtered water is extracted from the water tank 804 along direction 5 into the salt solution generating device 803 to realize the generation of salt solution with a specific concentration. It should be noted that the concentration of the generated salt solution is not limited in this embodiment, and can be adaptively configured according to the needs of the actual application scene. The water quantity and flow rate extracted by the first water pump 812 and the second water pump 813 can be controlled by setting the size of the driving signal of the first water pump 812 and the second water pump 813.

[0168] In the injection step of brine, the control valve controls the sixth switch 810 to conduct, and it should be noted that the water inlet of the sixth switch 810 is connected to the water outlet of the salt solution generating device 803. The control valve controls the second water pump 813 to enter the starting state, and the generated salt solution is extracted from the salt solution generating device 803 into the resin containing container 802. The seventh switch 811 is a check valve, which prevents the salt solution from flowing back from the water outlet of the resin containing container 802 to the salt solution generating device 803. When the second water pump 813 is in the starting state, the salt solution flows from the water outlet of the resin containing container 802 along direction 4 into the resin containing container 802, and flows from the water inlet of the resin containing container 802 along direction 3 into the resin containing container 802. During the process of the salt solution flowing through the resin flow channel of the resin containing container 802, the salt solution contacts the failed resin along the way to restore the softening capacity, and then the waste water is discharged through the sewage port of the water softening system.

[0169] In a more preferred embodiment, in the third working mode, the water outlet flow rate of the first water pump 812 and the water outlet flow rate of the second water pump 813 are kept consistent, so as to balance the water inlet flow rate and the water outlet flow rate of the salt solution generating device 803, prevent the accumulation of salt solution in the salt solution generating device 803, and affect the concentration of the generated salt solution in the subsequent salt solution generating step.

[0170] The water pump design and the salt solution generating device design in this embodiment realize the instant generation of salt solution, do not need to set a cavity for storing high-concentration salt solution, are beneficial to the small size design of the whole machine, and can keep the inside of the salt solution generating device 803 in a dry salt tank state, so that the whole machine can be kept in a cleaner state.

[0171] In an embodiment, the salt solution generating device 803 includes at least one salt dissolving flow channel, and the salt dissolving flow channel is arranged transversely in the salt solution generating device.

[0172] In actual application, due to the transverse arrangement of the salt dissolving flow channel, the liquid flows through the salt dissolving flow channel in a general horizontal direction, and the liquid can fully contact with the regenerated salt in the salt dissolving flow channel for a prolonged distance to form regenerated salt liquid with a certain concentration. The concentration of the regenerated salt liquid can be further controlled by controlling the flow rate, temperature of the water body entering the salt liquid generating device, and the length of the salt dissolving flow channel.

[0173] Specifically, the salt liquid generating device 803 in the embodiment can also be a single-layer salt dissolving flow channel structure or a multi-layer salt dissolving flow channel structure. The salt dissolving flow channel structure of the salt liquid generating device 803 is not limited in the embodiment and can be adaptively configured according to the actual application scenario.

[0174] In one embodiment, if the system control instruction is used to implement the fourth working mode, the controller controls the corresponding waterway switch piece to be in an open state and controls the corresponding power assembly to be in a start state, so that the water body flows into the resin containing container in a reverse direction according to a preset flow rate to reversely slow wash the resin containing container.

[0175] As shown in FIG. 13, if the system control instruction is used to implement the fourth working mode, the controller controls the fourth switch piece 808, the fifth switch piece 809, the sixth switch piece 810, and the seventh switch piece 811 to be in an open state, controls the second water pump 813 to be in a start state, controls other switch pieces to be in a closed state, and controls the first water pump 812 to be in a stop state, so that the water body flows from the water inlet of the water softening system to the sewage outlet of the water softening system in sequence through the pre-filter 801, the fifth switch piece 809, the water inlet of the water tank 804, the second water outlet of the water tank 804, the sixth switch piece 810, the second water pump 813, the seventh switch piece 811, the water outlet of the resin containing container 802, the water inlet of the resin containing container 802, and the fourth switch piece 808.

[0176] Specifically, the fourth working mode is a slow washing mode. In the slow washing mode, the salt not fully utilized in the resin containing container 802 can be utilized again, and the hardness ions replaced by the high-concentration salt liquid can be removed, so as to fully utilize the solid salt and fully regenerate the ion exchange resin in the resin containing container 802.

[0177] The principle of realizing the fourth working mode in the embodiment is that the purified water body passing through the pre-filter 801 is directly flowed to the water outlet of the resin containing container 802 through the second water outlet of the water tank 804, the sixth switch piece 810 and the seventh switch piece 811. In the fourth working mode, only the second water pump 813 is controlled to be started, at this time, the sixth switch piece 810 is turned on and connected with the water inlet in the direction of the second water outlet of the water tank 804, so that the filtered water body is not flowed through the salt solution generating device 803, and is directly flowed to the water outlet of the resin containing container 802 along the direction 6. The replaced hardness ions are carried out along the water flow direction, and the underutilized salt is fused to regenerate the resin, and finally the waste water is discharged through the sewage outlet of the soft water system.

[0178] The embodiment can ensure the full utilization of solid salt and the full regeneration of the resin in the resin containing container 802 through the working condition design and the water path design of the slow washing mode, and can greatly improve the regeneration rate of the resin regeneration of the soft water system and the softening efficiency of the water body.

[0179] In one of the embodiments, as shown in FIG. 14, the water tank 804 further includes a liquid level sensor arranged on the inner wall of the water tank 804. It should be noted that the specific arrangement position of the liquid level sensor is not limited in the embodiment, and can be adaptively arranged according to the preset liquid level threshold requirement in the actual application scene.

[0180] If the liquid level in the water tank 804 is less than the preset liquid level threshold, the controller controls the fifth switch piece 809 to be in the open state, controls other switch pieces to be in the closed state, and controls all water pumps to be in the stop state, so that the water body is sequentially flowed from the water inlet of the soft water system to the water tank 804 through the pre-filter 801, the fifth switch piece 809 and the water inlet of the water tank 804, until the liquid level in the water tank 804 is greater than or equal to the preset liquid level threshold.

[0181] Specifically, the embodiment can ensure that the water amount in the water tank 804 can meet the control requirement of the water pump pumping flow before entering the third working mode or the fourth working mode by arranging the liquid level sensor.

[0182] If the liquid level in the water tank 804 is greater than or equal to the preset liquid level threshold, and the system control instruction is used to implement the third working mode, the controller controls the fourth switch 808, the fifth switch 809, the sixth switch 810, and the seventh switch 811 to be in an open state, controls other switches to be in a closed state, and controls the first water pump 812 and the second water pump 813 to be in a start state, so that the water flows from the first water outlet of the water tank 804 to the sewage outlet of the water softening system in sequence through the first water pump 812, the water inlet of the brine generating device 803, the water outlet of the brine generating device 803, the sixth switch 810, the second water pump 813, the seventh switch 811, the water outlet of the resin containing container 802, the water inlet of the resin containing container 802, and the fourth switch 808 at a preset flow rate.

[0183] If the liquid level in the water tank 804 is greater than or equal to the preset liquid level threshold, and the system control instruction is used to implement the fourth working mode, the controller controls the fourth switch 808, the fifth switch 809, the sixth switch 810, and the seventh switch 811 to be in an open state, controls the second water pump 813 to be in a start state, controls other switches to be in a closed state, and controls the first water pump 812 to be in a stop state, so that the water flows from the second water outlet of the water tank 804 to the sewage outlet of the water softening system in sequence through the sixth switch 810, the second water pump 813, the seventh switch 811, the water outlet of the resin containing container 802, the water inlet of the resin containing container 802, and the fourth switch 808.

[0184] Specifically, the switch control and water pump control of the embodiment in different working modes can refer to the control process in the corresponding working mode of the foregoing embodiment, which will not be described here.

[0185] Specifically, in the actual working process of the embodiment, for the regeneration step of the resin containing container 802, the water pump needs to be controlled to extract at a preset flow rate and a preset flow rate after the water amount in the water tank 804 meets a certain water amount threshold. The preset flow rate and the preset flow rate are not limited in the embodiment, and can be adaptively configured according to the needs of the actual application scene to maximize the resin regeneration efficiency and stabilize the brine concentration.

[0186] In one embodiment, as shown in FIG. 14, the water softening system in the embodiment further includes an eighth switch 814, and the water outlet of the pre-filter 801 is connected to the water outlet of the water softening system through the eighth switch 814. The eighth switch 814 in the embodiment can be an electromagnetic valve. It should be noted that the specific type of the eighth switch is not limited in the embodiment and can be configured according to the needs of the actual application scene.

[0187] Specifically, the embodiment further provides an eighth switch 814 directly connected to the water outlet of the pre-filter 801 and the water outlet of the water softening system. In specific embodiments, if the system control instruction is used to implement the first working mode, the controller controls the eighth switch 814 to be in a closed state.

[0188] If the system control instruction is used to implement the second working mode, the third working mode or the fourth working mode, the controller controls the eighth switch 814 to be in an open state, so that the water body flows from the water inlet of the water softening system to the water outlet of the water softening system in sequence through the pre-filter 801 and the eighth switch 814.

[0189] Specifically, the water softening system in the embodiment can control the eighth switch 814 to be open when implementing the resin containing container 802 backwashing mode, salt absorption regeneration mode and slow washing mode, so as to ensure that the water softening system can continuously supply filtered water to the water outlet, and avoid affecting the normal water supply process of the water softener equipment. It should be noted that the water supplied by the water softening system at this time is filtered water that has been preliminarily purified by the pre-filter 801.
