Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water softener equipment, in particular to a resin regeneration control method and device, a water softening system, equipment and a medium. BACKGROUND

[0002] 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 to effectively remove hardness ions in water bodies and soften 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.

[0003] The conventional water softener generates brine of a target concentration for ion exchange resin regeneration, including a salt dissolving step and a siphon step. The salt dissolving step requires continuous water and salt addition to the salt tank loaded with regeneration salt particles. After the regeneration salt particles in the salt tank are dissolved for a certain period of time, high-concentration brine is formed. The siphon step uses the water pressure of the siphon component connection to form a siphon effect, and the high-concentration brine stored in the salt tank is sucked out, combined with the tap water at the siphon component connection, to form brine of a target concentration for regenerating ion exchange resin.

[0004] This scheme for generating brine of a target concentration through a siphon component is affected by the water pressure of the entire machine in the siphon step, which can cause unstable brine concentration for ion exchange resin regeneration. It takes a long time to generate high-concentration brine, and the instant resin regeneration is poor. SUMMARY

DETAILED DESCRIPTION

[0064] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0065] As described in the foregoing background section, in the soft water system in the prior art, the generation of resin regeneration brine is usually realized by using a siphon device. Due to the siphon characteristics of the device itself, the salt concentration and salt density of the regeneration brine cannot be accurately controlled due to the instability of water pressure, thereby causing the instability of the resin regeneration effect. Moreover, the generation of the regeneration brine by using the siphon device consumes a large amount of regeneration salt, which not only causes the waste of the regeneration salt, but also the discharge of the high-concentration brine easily causes environmental pollution.

[0066] The resin regeneration control method provided by the embodiments of the present application can effectively solve the problem that the salt concentration of the regeneration brine cannot be accurately controlled in the resin regeneration process.

[0067] Specifically, the soft water system in the present embodiment at least includes an instant salt dissolving and regeneration device and a resin container. Specifically, as shown in Figure 1 The instant regeneration device at least includes a water tank 104, a first water pump 112, a salt tank 103 and a second water pump 113, and the second water pump 113 is connected with the resin container 102. It should be understood that the soft water system in the present embodiment further includes a controller, and the controller is connected with the first water pump 112 and the second water pump 113 respectively, so as to control the water inflow and outflow of the salt tank 103 by controlling the water pumping flow of the first water pump 112 and the second water pump 113. Thus, the influence of the water pressure fluctuation on the siphon device can be effectively overcome, and the control of the concentration of the regeneration brine can be improved.

[0068] In one embodiment, as shown in Figure 2 A resin regeneration control method is provided. Taking the soft water system in Figure 1 as an example, the method includes the following steps:

[0069] S201, obtaining a target running time of a salt suction and regeneration station corresponding to a regeneration mode of a soft water system.

[0070] Specifically, the resin regeneration control method in the embodiment is mainly implemented when the water softening system is in the regeneration mode. It should be noted that the water softening system includes a water production mode and a regeneration mode. The water production mode is used to exchange hardness ions in water through ion exchange resin to achieve water softening to obtain soft water. The regeneration mode is used to regenerate the ion exchange resin by using brine with a preset concentration to restore the hardness ion exchange capacity of the ion exchange resin, thereby facilitating efficient use of the ion exchange resin.

[0071] In the regeneration mode, the water softening system at least includes a backwashing station and a salt dissolving regeneration station. In the backwashing station, the water softening system controls the water to flow into the resin container from the water outlet and flow out of the resin container from the water inlet, so as to backwash the ion exchange resin in the resin container by using the water, and remove the hardness ions remaining on the pipeline or surface of the ion exchange resin, thereby providing better environmental conditions for subsequent salt dissolving regeneration.

[0072] In the salt dissolving regeneration station, the water softening system generates brine with a preset concentration, and controls the brine to flow into the resin container from the water outlet and flow out of the resin container from the water inlet, so as to make the regenerated salt contact with the ion exchange resin by flowing through the pipeline and surface of the ion exchange resin in the resin container, thereby achieving regeneration of the ion exchange resin.

[0073] In a feasible embodiment, the regeneration mode further includes at least a slow washing station. In the slow washing station, the water softening system controls the water to bypass the salt tank and flow into the resin container from the water outlet and flow out of the resin container from the water inlet again, so as to use the regenerated salt remaining in the water softening system in the salt dissolving regeneration station to fully regenerate the ion exchange resin in the resin container, and fully utilize the regenerated salt in the water pipeline, thereby reducing waste of the regenerated salt.

[0074] In specific embodiments, the parameters affecting resin regeneration include the operation time of each station in the regeneration mode, the concentration and density of the regenerated brine, the water inflow and outflow of the salt tank, the length of the resin flow channel in the resin container, the length of the salt dissolving flow channel in the salt tank, and the amount of regenerated salt, etc.

[0075] In the embodiment, the target operation time of the salt sucking regeneration station is obtained in advance when the salt sucking regeneration station is executed, so as to achieve instant control of resin regeneration. The water softening system provided by the embodiment is different from the water softening system using a siphon device, and can accurately calculate the target operation time before the salt sucking regeneration station is executed, and is not affected by siphon effect or water pressure, so as to more accurately control the concentration of the regenerated brine.

[0076] S202, control the first water pump to draw water from the water tank to the salt tank according to the first water pumping flow rate.

[0077] Specifically, the first water pump is arranged between the water outlet of the water tank and the water inlet of the salt tank. The first water pumping flow rate is corresponding to the water inlet flow rate of the salt tank. In an actual application scenario, the running power of the first water pump determines the water inlet parameters of the salt tank, wherein the water inlet parameters include but are not limited to the water inlet flow rate and the water inlet flow speed. When the first water pump is controlled to pump water at the first water pumping flow rate, the first water pump will be kept running at the corresponding running power to ensure the stability of the water pumping flow rate.

[0078] The embodiment can realize precise control of the water inlet flow rate of the salt tank through precise control of the water pumping power of the first water pump. It should be noted that the specific value of the first water pumping flow rate can be determined according to the demand for the water inlet flow rate of the salt tank in an actual application scenario, which is not specifically limited here.

[0079] S203, after the preset time, the second water pump is controlled to pump the target salt liquid from the salt tank to the resin container at a second water pumping flow rate.

[0080] Specifically, the second water pump is arranged between the water outlet of the salt tank and the resin container. The second water pumping flow rate is corresponding to the water outlet flow rate of the salt tank. In an actual application scenario, the running power of the second water pump determines the water outlet parameters of the salt tank, wherein the water outlet parameters include but are not limited to the water outlet flow rate and the water outlet flow speed.

[0081] The embodiment can realize precise control of the water outlet flow rate of the salt tank through precise control of the water pumping power of the second water pump. It should be noted that the specific value of the second water pumping flow rate can be determined according to the demand for the water inlet flow rate of the salt tank in an actual application scenario, which is not specifically limited here.

[0082] In an actual application process, there is a certain time interval, i.e., a preset time, between the starting times of the first water pump and the second water pump. Since there are still some pipelines between the first water pump and the water inlet of the salt tank and between the water outlet of the salt tank and the second water pump, and it is necessary to ensure that the water enters the salt tank and flows through the salt liquid collecting cavity, in order to avoid the phenomenon of empty pumping of the second water pump, the second water pump is started after the preset time from the starting time of the first water pump. It should be noted that the preset time is not specifically limited in the embodiment and can be determined according to the pipeline length, the type of the salt tank and the specific position of the salt liquid collecting cavity of the salt tank in an actual application scenario.

[0083] In a specific embodiment, a corresponding liquid level switch can be arranged in the salt liquid collecting cavity of the salt tank. When the liquid level switch feeds back a liquid level signal to the controller, the controller starts the second water pump and controls the second water pump to perform a water pumping action at the second water pumping flow rate.

[0084] Specifically, when the first water pump pumps the water in the water tank into the salt tank according to the preset water inlet flow rate, the solid salt stored in the salt tank combines with the water to form target salt solution with a certain concentration. With the power of the second water pump according to the preset water outlet flow rate, the target salt solution formed in the salt tank is pumped into the resin container by the second water pump at the moment, so as to realize efficient regeneration of the ion exchange resin in the resin container.

[0085] S204, after the first water pump runs for the target running time, the first water pump is controlled to stop.

[0086] Specifically, after the first water pump pumps water according to the first water pumping flow rate for the target running time, it means that the total amount of water passing through the salt tank in the salt regeneration station reaches the preset threshold value. At this time, the first water pump is controlled to stop, and the water inlet flow rate of the salt tank is accurately controlled to ensure that the salt tank generates target salt solution with a preset concentration. It should be noted that the preset threshold value corresponding to the total amount of water passing through the salt tank can be configured according to the requirements of the actual application scene.

[0087] S205, after the second water pump runs for the target running time, the second water pump is controlled to stop.

[0088] Specifically, after the second water pump pumps water according to the second water pumping flow rate for the target running time, it means that a certain amount of regenerated salt solution has been generated, and the total amount of regenerated salt solution output by the salt tank reaches the preset threshold value. At this time, the second water pump is controlled to stop, and the total amount of regenerated salt solution output by the salt tank can be accurately controlled. It should be noted that the preset threshold value corresponding to the total amount of regenerated salt solution output by the salt tank can be configured according to the requirements of the actual application scene.

[0089] In summary, the resin regeneration control method provided by the embodiment can effectively avoid the instability of salt concentration caused by the siphon device, more accurately control the salt concentration of the target salt solution, greatly improve the utilization rate of regenerated salt in the soft water system, effectively save the amount of regenerated salt, and avoid the environmental pollution problem caused by excessive discharge of concentrated salt water.

[0090] In one embodiment, the embodiment provides an accurate calculation method of the target running time, as shown in Figure 3 S201, comprising:

[0091] S301, obtaining the target concentration corresponding to the target salt solution, the target total amount of regenerated salt of the salt tank, and the target water outlet flow rate of the salt tank;

[0092] S302, calculating the target running time according to the target total amount of regenerated salt, the target water outlet flow rate, and the target concentration.

[0093] Specifically, before the salt absorption and regeneration station, the target concentration of the target brine and the target water flow of the salt tank can be determined in advance according to the specific situation of the ion exchange resin in the resin container. After determining the target water flow of the salt tank, the target water pumping flow of the second water pump can be obtained. After determining the target concentration of the target brine and the target water flow of the salt tank, the total amount of the target regeneration salt to be used can be calculated.

[0094] It should be noted that the weight of the regeneration salt in the salt tank can be slightly greater than the total amount of the target regeneration salt calculated here to ensure that the salt tank can generate target brine with sufficient concentration.

[0095] In one embodiment, S301 further comprises:

[0096] The brine concentration, the total amount of regeneration salt, and the water flow of the salt tank in the system default state are obtained as the target concentration, the target total amount of regeneration salt, and the target water flow.

[0097] In actual execution, the target concentration of the target brine, the target water flow of the salt tank, and the target total amount of regeneration salt can also be the concentration, water flow, and total amount of regeneration salt set in the system default state. The parameters set in the system default state can be configured according to the actual application scenario of the water softening system. When the weight of the regeneration salt in the salt tank is less than or equal to the preset weight threshold, the water softening system will prompt the user to replenish the regeneration salt in time to ensure the normal implementation of the resin regeneration control method in this embodiment.

[0098] In one embodiment, S301 further comprises:

[0099] The custom brine concentration, the total amount of regeneration salt, and the water flow of the salt tank are obtained as the target concentration, the target total amount of regeneration salt, and the target water flow.

[0100] In actual application, the target concentration of the target brine, the target water flow of the salt tank, and the target total amount of regeneration salt can also be the brine concentration, the total amount of regeneration salt, and the water flow of the salt tank set by the user according to the actual application scenario. Specifically, the user can set the parameters according to the specific needs in the actual application scenario to ensure that the resin regeneration control method generates target brine with more accurate concentration.

[0101] In a specific implementation, it is assumed that the target concentration corresponding to the target brine is (wt%), the density of the regeneration salt particles is (g / cm 3 ), the total amount of the regeneration salt in the salt tank is (g), and the water flow of the second water pump is (mL / min).

[0102] The calculation formula of the target running time is Wherein, T is the target running time, in minutes (min).

[0103] In one embodiment, as shown in Figure 4 Before S201, the resin regeneration control method further comprises:

[0104] S401, obtaining the real-time water production of the water softening system in the water production mode;

[0105] S402, if the real-time water production is greater than or equal to the preset period water production, determining whether the running time of the water production mode is greater than or equal to the target time threshold;

[0106] S403, if the running time of the water production mode is greater than or equal to the target time threshold, controlling the water softening system to enter the regeneration mode.

[0107] Specifically, the embodiment further determines whether the water softening system meets the condition of switching to the regeneration mode by monitoring the real-time water production of the water softening system in the water production mode and the total running time of the water softening system in the water production mode.

[0108] In actual execution process, the flow meter can be arranged at the water outlet of the water softening system to obtain the water production of the water softening system. And the water production counted by the flow meter is reset every time the water production mode and the regeneration mode are switched, so as to ensure that the water softening system can produce enough soft water in the water production mode, and the ion exchange resin in the resin container can be regenerated in time.

[0109] The embodiment sets the water production and the running time as the judgment conditions for switching to the regeneration mode, so that the entering time of the regeneration mode can be determined more accurately, and the softening capacity and the regeneration capacity of the water softening system are ensured.

[0110] In one embodiment, as shown in Figure 5 After the water softening system is controlled to enter the regeneration mode, the resin regeneration control method further comprises:

[0111] S501, controlling the water softening system to execute the backwashing station for a preset backwashing time;

[0112] S502, controlling the water softening system to execute the salt absorption regeneration station for a target running time;

[0113] S503, controlling the water softening system to execute the slow washing station for a preset slow washing time.

[0114] In specific embodiments, each station has a corresponding running time. In the backwashing station, it is necessary to ensure that the resin container in the soft water system can be fully cleaned, so that the hardness ions inside the resin container are mostly removed, thereby facilitating the full contact of the ion exchange resin with the target salt solution and achieving full regeneration of the ion exchange resin.

[0115] In the salt absorption regeneration station, it is necessary to ensure that the salt tank generates a target salt solution with sufficient concentration, and to control the flow of the target salt solution in the pipeline according to the specified flow rate, so as to facilitate the full contact of the ion exchange resin with the salt solution and achieve efficient regeneration of the ion exchange resin.

[0116] In the slow washing station, it is necessary to ensure that the residual regenerated salt in the soft water system is fully utilized, thereby further improving the utilization rate of the regenerated salt and the regeneration efficiency of the ion exchange resin.

[0117] Specifically, the preset backwashing time can be determined according to the actual application scenario of the soft water system, which is not limited here. The preset slow washing time can detect the total dissolved solids (TDS) value of the water outlet of the soft water system and the TDS value of the water inlet in real time, and ensure that the difference between the TDS value of the water outlet and the TDS value of the water inlet is within a preset TDS value threshold range. Specifically, when the difference between the TDS value of the water outlet and the TDS value of the water inlet is within the preset TDS value threshold range, the soft water obtained by water softening through the resin container after stopping the slow washing station will not have an odor and will not affect the normal use of the soft water system. It should be noted that the TDS value threshold can be 200 mg / L, and the TDS value threshold is not limited in the present embodiment.

[0118] In one embodiment, the instant solution regeneration device further comprises a heating module, the first water pump is connected to the salt tank through the heating module, and the resin regeneration control method further comprises:

[0119] S601, controlling the first water pump to draw water from the water tank to the salt tank through the heating module according to a third water pumping flow rate;

[0120] S602, controlling the heating module to heat the water body according to a preset heating power;

[0121] S603, after a preset time, controlling the second water pump to draw the target salt solution from the salt tank to the resin container according to a fourth water pumping flow rate.

[0122] Specifically, the heating module in the present embodiment can heat the water body according to the control instruction of the control module. In actual application, the heating module can heat the water body to be added to the salt tank or the resin container to a target temperature. The present embodiment improves the resin regeneration efficiency by controlling the temperature of the water body.

[0123] Specifically, the heating module can be a heating body assembly capable of heating the water in the pipeline as a whole, thereby controlling the temperature of the water in the soft water system. The specific product type of the heating module is not limited in the embodiment, and can be configured according to the actual application scenario.

[0124] In actual application, the first water pump draws water from the water tank to make the water enter the salt tank through the heating module, and the water flow reaching the salt liquid collecting cavity in the salt tank is a third water flow. The third water flow can be the same as or different from the first water flow, and the embodiment does not make a specific limitation thereon. The specific value of the third water flow can be determined according to the actual application scenario.

[0125] Specifically, the determination process of the preset time for the first water pump to draw water at the third water flow in the embodiment can refer to the determination process of the preset time described above, which will not be described here.

[0126] Specifically, the embodiment further includes an instant salt dissolving control station. In actual application, the preset heating power of the heating module can be controlled to adjust the temperature of the water entering the salt tank or the resin container in real time, so as to ensure that the water temperature is always the optimal temperature for resin regeneration, thereby further improving the resin regeneration efficiency and effectively improving the utilization rate of regenerated salt.

[0127] Specifically, in one embodiment, S602 includes:

[0128] The real-time temperature of the water entering the heating module and the preset reference temperature are obtained. Specifically, a temperature detection device such as a temperature sensor or a temperature sensing assembly can be arranged in front of the heating module to collect the real-time temperature of the water entering the heating module. The preset reference temperature in the embodiment is the standard temperature of the water output from the water tank based on different seasons. In specific embodiments, since the optimal temperature of the regenerated salt liquid is determined, the regenerated salt liquid at the optimal temperature can greatly improve the regeneration effect of the ion exchange resin. The temperature of the water output from the water tank will change with the change of the season. At this time, by obtaining the real-time temperature and the preset reference temperature in advance, the heating module can be heated at an accurate heating power to keep the regenerated salt liquid at the optimal temperature.

[0129] Specifically, if the real-time temperature is equal to the preset reference temperature, the heating module is controlled to heat the water at a first heating power. If the real-time temperature is greater than the preset reference temperature, the heating module is controlled to heat the water at a second heating power, wherein the second heating power is less than the first heating power. If the real-time temperature is less than the preset reference temperature, the heating module is controlled to heat the water at a third heating power, wherein the third heating power is greater than the first heating power.

[0130] In specific embodiments, the first heating power is a default power of the heating module, i.e., when the real-time temperature is equal to the preset reference temperature, the heating module heats the water body according to the default power. The specific value of the default power is not limited in this embodiment, and can be adaptively adjusted according to the actual application scenario.

[0131] When the real-time temperature is greater than the preset reference temperature, the heating power is appropriately reduced, the heating module is controlled to heat the water body at the second heating power, and the temperature of the regenerated brine can be more accurately controlled. When the real-time temperature is less than the preset reference temperature, the heating power is appropriately increased, the heating module is controlled to heat the water body at the third heating power, and the temperature of the regenerated brine can be more accurately controlled.

[0132] In one embodiment, S602 further includes:

[0133] If the real-time temperature is greater than or equal to the optimal brine temperature, the heating module is controlled not to heat the water body.

[0134] In specific embodiments, the optimal brine temperature is greater than the preset reference temperature. When the real-time temperature is greater than or equal to the optimal brine temperature, the heating module does not need to heat the water body, and the brine tank can directly generate regenerated brine with the optimal brine temperature according to the water body output by the water tank.

[0135] In one embodiment, the resin regeneration control method further includes:

[0136] Controlling the first water pump to reduce the water pumping flow or controlling the heating module to increase the heating power to increase the concentration of the target brine;

[0137] Controlling the first water pump to increase the water pumping flow or controlling the heating module to reduce the heating power to reduce the concentration of the target brine.

[0138] Specifically, since the concentration of the target brine needs to be determined according to the real-time state of the ion exchange resin in the resin container, there is also a control demand to increase or decrease the concentration of the target brine in the actual application process. For example, if the user observes that the ion exchange resin in the resin container cannot be fully regenerated under the regeneration of the target brine at the default concentration, a higher target concentration can be set on the softening system. When the concentration demand of the target brine increases, the concentration of the target brine can be increased by controlling the first water pump to reduce the water pumping flow or controlling the heating module to increase the heating power, so as to further improve the regeneration capacity of the ion exchange resin.

[0139] Similarly, if the ion exchange resin in the resin container can be fully regenerated under the regeneration of the target brine at the default concentration, a lower target concentration can be set on the softening system. When the concentration demand of the target brine decreases, the first water pump can be controlled to increase the water pumping flow or the heating module can be controlled to reduce the heating power.

[0140] It should be noted that the water pumping flow rate of the first water pump and the heating power of the heating module can also be increased or decreased simultaneously, and the embodiment limits the adjustment action of the specific application scenario.

[0141] In addition, in a feasible embodiment, the concentration of the target brine can also be adjusted by adjusting the length of the salt dissolving flow channel of the salt tank. In specific embodiments, the concentration of the target brine can be increased by increasing the length of the salt dissolving flow channel, and the concentration of the target brine can be reduced by reducing the length of the salt dissolving flow channel.

[0142] In one embodiment, the resin regeneration control method further comprises:

[0143] When the first water pump and the second water pump are operated simultaneously, the water pumping flow rate of the first water pump is the same as the water pumping flow rate of the second water pump. That is, the first water pumping flow rate is the same as the second water pumping flow rate, and the third water pumping flow rate is the same as the fourth water pumping flow rate.

[0144] In the specific implementation process, when the first water pump and the second water pump are operated simultaneously, the water inflow rate and the water outflow rate of the salt tank need to be kept consistent to avoid the accumulation of regenerated salt in the salt dissolving flow channel or the brine collecting cavity of the salt tank. The embodiment controls the water pumping flow rate of the first water pump to be the same as the water pumping flow rate of the second water pump when the first water pump and the second water pump are operated simultaneously, so as to keep the water inflow rate and the water outflow rate of the salt tank consistent.

[0145] In summary, the embodiment provides a resin regeneration control method, which can not only avoid the influence of the water pressure fluctuation of the siphon device on the soft water system and realize precise control of the target brine concentration, but also can adjust the generation process of the target brine in real time according to various actual application conditions of the soft water system, accurately adjust the water inflow rate, the water outflow rate, the water temperature and other parameters of the salt tank, and realize efficient utilization of regenerated salt and efficient regeneration of ion exchange resin.

[0158] In summary, this embodiment provides a resin regeneration control device that not only avoids the influence of water pressure fluctuations in the soft water system caused by the siphon device, thus achieving precise control of the target brine concentration, but also allows for real-time adjustment of the target brine generation process according to various actual application conditions of the soft water system. This enables precise adjustment of parameters such as the inlet flow rate, outlet flow rate, and water temperature of the brine tank, thereby achieving efficient utilization of regenerated salt and efficient regeneration of ion exchange resin.

[0159] Each module in the aforementioned resin regeneration control device can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device, or stored in the memory of a computer device as software, so that the processor can call and execute the operations corresponding to each module.

[0160] In one embodiment, a soft water system is also provided, including a processor, a memory, an instant salt dissolving and regeneration device, and a resin container. The instant salt dissolving and regeneration device includes a water tank, a first water pump, a salt tank, and a second water pump connected in sequence. The second water pump is also connected to the resin container. The memory stores a computer program, and when the processor executes the computer program, it implements the steps of the resin regeneration control method in the aforementioned method embodiment.

[0161] For example, such as Figure 1 As shown, this embodiment provides a water softening system, which includes a pre-filter 101, a resin container 102, a brine tank 103, a water tank 104, a controller, a first switch 105, a second switch 106, a third switch 107, a fourth switch 108, a fifth switch 109, a sixth switch 110, a seventh switch 111, a first water pump 112, a second water pump 113, an eighth switch 114, and a heating module 115.

[0162] Specifically, the inlet of the pre-filter 101 is connected to the inlet of the softening water system, and the outlet of the pre-filter 101 is connected to the inlet of the resin container 102 via a first switch 105. The outlet of the resin container 102 is connected to the outlet of the softening water system via a second switch 106. The inlet of the softening water system is used to connect to the raw water body. In practical applications, the raw water body is usually tap water; this embodiment does not limit the type of raw water body. The outlet of the softening water system is used to output softened water that has undergone filtration and softening treatment.

[0163] The water outlet of the pre-filter 101 is connected to the water outlet of the resin container 102 through a third switch 107, and the water inlet of the resin container 102 is connected to the sewage outlet of the water softening system through a fourth switch 108.

The second water outlet of the water tank 104 is connected to the water outlet of the resin container 102 through the sixth switch 110, the second water pump 113 and the seventh switch 111 in sequence.

It should be noted that the resin container 102 in the embodiment is placed in a horizontal manner, that is, the water flow direction is parallel to the ground and flows in a horizontal direction inside the tank body. Compared with the conventional water softening machine which is placed in a manner that the water flow direction is perpendicular to the ground, the resin container 102 in the embodiment is more flat and does not occupy height space, so that the size of the water softening machine can be effectively reduced.

[0168] In addition, the resin container 102 in the embodiment can only include one layer of resin flow channels, so that the tank flow is a single one-channel flow. The resin container 102 in the embodiment can also include multiple layers of resin flow channels, which are separated by a partition plate.

In a preferred embodiment, the resin container 102 with a multi-layer resin flow channel structure in the embodiment can effectively increase the effective contact distance of water and resin, thereby improving the softening performance of the soft water system.

[0169] The salt tank 103 in the embodiment is used to load solid salt, and the filtered water in the mixing water tank 104 can form a high-concentration salt solution. The embodiment can control the salt concentration of the salted water by adjusting the water flow into the salt tank 103 and adjusting the length of the salt dissolving channel inside the salt tank 103. The length of the salt dissolving channel of the salt tank 103 in the embodiment can be a single layer of flow channels or multiple layers of flow channels, and the specific structure of the salt tank 103 is not limited in the embodiment. In a preferred embodiment, by setting different numbers of partition plates inside the salt tank 103, 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 water concentration of the generated salt solution is improved.

[0170] The salt tank 103 in the embodiment adopts an instant salt solution generation method, which can control the flow rate and flow of water in the salt tank 103 by controlling the driving force of the first water pump 112 and the second water pump 113, thereby stably achieving high-precision salt solution concentration control, effectively improving the utilization rate of the salt solution, and improving the regeneration efficiency of the resin.

[0171] The water tank 104 in the embodiment is used to store the filtered water filtered by the pre-filter, and is used in the corresponding working mode.

[0172] The switch in the embodiment is used to realize water path switching control in various working modes, so that the water flows in the specified direction, thereby completing the softening output process of the water, the backwashing process of the resin container 102, the regeneration process of the resin container 102, and the like. In a specific embodiment, the first switch 105, the second switch 106, the third switch 107, the fourth switch 108, the fifth switch 109 are all electromagnetic valve switches, the sixth switch 110 is a one-bit two-way electromagnetic valve, and the seventh switch 111 is a check valve.

The three water outlets of the one-bit three-way electromagnetic valve are respectively connected to the water inlet of the resin container 102, the water outlet and the water inlet of the water tank 104.

[0174] Specifically, the eighth switch 114 directly connected to the water outlet of the pre-filter 101 and the water outlet of the water softening system is further provided in the embodiment. In a specific embodiment, the eighth switch can be kept open in the regeneration mode to ensure that the water outlet of the water softening system can always provide water.
