Description

TECHNICAL FIELD

[0001] The present application relates to the field of soft water preparation, in particular to a full-automatic soft water preparation method. BACKGROUND

[0002] The soft water machine generally adopts ion exchange resin technology to remove calcium and magnesium ions in water, thereby reducing the generation of scale and improving the water experience of bathing and washing. After using for a period of time, the ion exchange resin is saturated with adsorbed calcium and magnesium ions, and needs to be regenerated by using a concentrated sodium chloride solution to restore performance. Therefore, the soft water machine usually needs to switch back and forth between normal operation mode and regeneration mode, and the regeneration mode usually includes multiple programs such as water injection, salt dissolution, salt adsorption, forward washing or backwashing, which requires multiple water path switching. Among them, the soft water valve is the core component of the soft water machine, and through the soft water valve, the switching of multiple water paths can be realized to realize different function modes. However, the traditional soft water valve uses a single plunger to move in multiple positions in the cavity to realize the switching of all water paths in the normal operation mode and the regeneration mode, which has the problems of long plunger running distance, multiple stop positions, high requirements for manufacturing precision and motion control precision, easy to malfunction, water leakage, and mixing of salt water and sewage water into the normal water pipeline during regeneration, which affects the customer experience and the water equipment in the user's home. SUMMARY

At the same time, the problems of too many components and complex assembly in the existing products are solved; the structure can also realize bypass function by being equipped with a three-way ball valve or an electromagnetic valve, and can realize water path closing by being equipped with a two-way electromagnetic valve and an electric ball valve, which is safer and more reliable.

[0012] As a further scheme of the application, the process of realizing positive washing function is that a three-way ball valve is connected to the second water outlet hole, one end of which is a soft water pipe and the other end of which is a sewage pipe, wherein the piston unit position of the positive washing and the soft water preparation is consistent.

[0013] As a further scheme of the application, the process of realizing water injection function is that water enters the cavity from the third water inlet hole, exits the cavity from the third water outlet hole on the other side of the cavity through the passage formed by the third piston unit, enters the jet flow channel, and enters the brine tank through the jet flow hole to dissolve brine.

[0014] As a further scheme of the application, the process of realizing regeneration function is that water enters the cavity from the third water inlet hole, exits the cavity from the third water outlet hole on the other side of the cavity through the passage formed by the third piston unit, enters the jet flow channel, forms negative pressure through the Venturi principle, absorbs the concentrated brine in the brine tank through the jet flow hole and mixes, enters the cavity through the jet flow component hole and comes out from the fourth water outlet hole through the first piston unit, comes out from the bottom of the center pipe through the connecting pipe, and is regenerated through the resin layer, while the salt water enters the cavity through the connecting pipe and the fourth water inlet hole, and is discharged from the fifth water outlet hole on the other side through the passage formed by the first piston unit.

[0023] The present application will be further described below in combination with the drawings and related knowledge, and will be clearly and completely described. Obviously, the described application is only a part of the embodiments of the present application, but not all the embodiments.

[0024] The present application solves the problem that the plunger of the traditional soft water valve needs to set more sealing rings and longer moving stroke due to multiple stay positions, resulting in larger resistance. During the movement of the plunger, multiple sealing rings of different sizes and specifications repeatedly rub for a long time, which increases the probability of wear of the sealing ring and increases the risk of water leakage of the soft water valve. The soft water valve plunger of the present application stays at fewer positions and has a shorter stroke. The number and specifications of the required sealing rings are uniform, the operation process is simple, and the friction time is short, thereby reducing the probability of wear of the sealing ring. At the same time, multiple sealing rings can be placed at the key part to reduce the risk of water leakage of the soft water valve. The traditional soft water valve uses a single column to move in the valve cavity for a long stroke, and the waterway in the valve cavity is complex, which may cause water leakage. During regeneration, if water is used at the same time during cleaning, salt water and sewage may be mixed into the normal water pipe, which reduces the operation reliability. The present application places different plungers in different cavities to reduce the complexity of the pipeline and ensure that they do not affect each other. During cleaning and regeneration, water leakage does not occur.

[0025] Referring to Figures 1-4 The present application provides a full-automatic soft water preparation method, which comprises the following steps:

[0026] Step S1: providing three piston units 1, the piston units 1 being located in the cavities 7; the piston units 1 being provided with a plurality of sealing plugs 3, and adjacent two sealing plugs 3 being used for waterway separation;

[0027] Step S2: driving the piston units 1 to move through the driving structure 2, the positions of the piston units 1 including an operation position, a forward washing position, a water injection position, and a regeneration position;

[0028] Step S3: the cavities 7 being provided with a plurality of water inlet holes and water outlet holes, the water inlet holes and the water outlet holes being in communication with the waterways separated by the sealing plugs;

[0029] Step S4: the waterways connected by the water inlet holes on the different piston units 1 and the water outlet holes corresponding to the water inlet holes, respectively realizing soft water preparation, forward washing, water injection, and regeneration;

[0030] In the present application, by changing the traditional single-piston mode to multiple piston units, by providing several sealing plugs 3 on the piston unit 1, and then driving the piston unit to move through the driving structure 2, the switching of multiple water paths during the preparation of soft water can be realized, and there is no influence between them, which can ensure the accuracy during the preparation of soft water; more specifically, the water path blocked by the sealing plug is entered through the water inlet hole, and then flows out through the water outlet hole; more specifically, since multiple piston units 1 and multiple water inlet holes and water outlet holes are provided, different functions can be realized on different piston units, thereby realizing the use of a partition structure, and the use of multiple plungers moving in multiple cavities to realize water path switching in running and regeneration modes, aiming to shorten the piston running distance, reduce the requirements for manufacturing precision and motion control precision, reduce the failure rate, and improve the operation reliability. At the same time, the problem of too many components and complex assembly in the existing product is solved.

[0031] As a further improvement, the sealing plugs 3 on the piston unit 1 are arranged according to the water path, and the spacing between adjacent sealing plugs 3 is adjustable, which means that it can be set as needed, for example, different spacings can be set according to the requirements of the water path during injection molding.

[0032] As a further improvement, the three piston units 1 are respectively a first piston unit 101, a second piston unit 102 and a third piston unit 103, each piston unit has a containing space for mutual separation, and further preferably, the first piston unit 101 is taken as an example for illustration, as shown in Figure 1 , the first piston unit 101 is provided with 7 sealing plugs 3, and adjacent sealing plugs 3 form a water path, in some other cases, in order to prevent water leakage, several sealing plugs 3 can be provided, for example, four sealing plugs 3 form a water path structure, and water leakage can also be prevented by providing two sealing rings on one sealing plug 3. Since the present application uses multiple piston units 1, the soft water valve plunger stays in a few positions and has a short stroke, the required sealing ring size is uniform, the operation process is simple, the friction time is short, and the wear probability of the sealing ring can be reduced. At the same time, multiple sealing rings can be placed in the key part to reduce the risk of water leakage of the soft water valve; and the traditional soft water valve uses a single column to move in the valve cavity with a long stroke, the water path in the valve cavity is complex, there will be a water leakage pipeline, and during regeneration, if water is used at the same time during cleaning, salt water and sewage will be mixed into the normal water pipeline, and the operation reliability is low. The present application places different plungers in different cavities, reduces the complexity of the pipeline, and achieves mutual independence, so that water leakage does not occur during cleaning and regeneration.

[0033] As a further improvement, the position of the driving piston unit includes a running position, a washing position, a water injection position and a regeneration position.

[0034] Referring to Figure 1 When the three piston units are in the running position, preparation of soft water is achieved, water enters the cavity from the first water inlet hole 1002, exits the cavity from the first water outlet hole 52 on the other side of the cavity through the passage formed by the second piston unit, enters the resin layer in the resin tank for softening, and then exits the resin tank from the center tube, enters the cavity from the second water inlet hole 60 through the connecting tube, and then enters the second water outlet hole 20 on one side through the passage formed by the second piston unit. The soft water is then provided through the second water outlet hole 20 and the water pipe. This position can also be the starting position of the motor drive or the origin position. In addition, it should be noted that the positions of the water inlet hole and the water outlet hole can be adjusted as needed, and the positions of the water inlet hole and the water outlet hole at this position are in communication with the sealing plug 3 in the second piston unit to form a water path structure. However, it is not excluded that the sealing plug 3 in other piston units is used to form a water path structure, that is, this scheme is the optimal communication scheme. For example, the sealing plug 3 in the first piston unit can also form a water path structure.

[0035] Referring to Figure 4 When the three piston units are in the washing position, the washing function can also be achieved. A three-way ball valve 14 is connected to the second water outlet hole, one end of which provides a soft water pipe, and the other end of which provides a sewage pipe. The piston unit positions of the washing position and the running position are the same, that is, the same as the running position, there is a three-way ball valve at the water outlet, which can be switched by the three-way ball valve. If the sewage pipe is switched at this time, it is washing, and vice versa, it is in the running state. The design of this structure can greatly reduce the structure of the traditional single valve, and the stability is higher, and there is no water leakage problem, and it is convenient for subsequent function expansion.

[0036] Referring to Figure 2 When the three piston units are in the water injection position, the water injection function is achieved, that is, the salt dissolving position. From the washing position, the three piston units are moved in the opposite direction of the motor, and further preferably the movement position can be detected by a light sensor or driven by a private motor. Water enters the cavity from the third water inlet hole 1001, enters the third water outlet hole 72 on the other side of the cavity through the passage formed by the third piston unit, enters the jet channel, and then enters the salt water tank through the jet hole 73 to dissolve the salt water. The jet is installed on the side of the cavity. Referring to the third piston unit 103 in Figure 2 and the third piston unit 103 in Figure 1 It can be seen that the third water inlet hole 1001 is located above the third piston unit 103, and the third water outlet hole 72 is located below the third piston unit 103. Referring to Figure 1 At this time, the third water outlet hole 72 is located between the two sealing plugs 3, forming a seal for the third water outlet hole 72; when the position is moved toFigure 2 After, the third water outlet hole 72 is located between the other two sealing plugs 3, thereby forming a passage with the third water inlet hole 1001; therefore, the biggest point of the present application is that the traditional single valve structure is decomposed into a structure composed of multiple piston units, which can achieve the same function, but the structure is simpler, and the stability and sealing of the waterway are better; as mentioned above, in order to achieve better sealing, multiple sealing rings or multiple sealing plugs can be used, thereby achieving more functions.

[0037] Referring to Figure 3 When the three piston units are located at the regeneration position or the slow washing position, the regeneration function and the backwashing function are realized; it should be pointed out that the present application can realize multiple functions at the same position, which is also not realized by the traditional single valve; the position is from Figure 2 the position to the opposite direction of the motor (driving structure), and a light sensor can also be used to collect the position; the driving mode is not limited, for example, a private server motor or other motors that can realize reciprocating motion can also realize the driving mode of the present application; water enters the cavity from the third water inlet hole 1001, enters the cavity through the passage formed by the third piston unit 103, and then enters the third water outlet hole 72 on the other side of the cavity, enters the jet flow channel, forms negative pressure through the Venturi principle, and absorbs the concentrated brine in the brine tank from the jet flow hole 73 and mixes it, then enters the cavity through the jet flow assembly hole 71 and is discharged from the fourth water outlet hole 30 through the first piston unit, then enters the central pipe to the bottom and is discharged, and then passes through the resin layer for regeneration; at the same time, the brine enters the cavity through the connecting pipe and the fourth water inlet hole 51, is discharged from the fifth water outlet hole 40 on the other side through the passage formed by the first piston unit; when the brine in the brine tank is washed, it enters the slow washing, that is, backwashing. Figure 2 and Figure 3 The position shares the water inlet from the third water inlet hole 1001 into the cavity, enters the cavity through the passage formed by the third piston unit 103, and then enters the third water outlet hole 72 on the other side of the cavity, enters the pipeline structure of the jet flow channel; it should be pointed out that referring to Figure 1 Fig. 3, the interval between the two sealing plugs 3 on the third piston unit 103 is relatively long, that is, in different positions, the process of sharing the water inlet from the third water inlet hole 1001 into the cavity, entering the cavity through the passage formed by the third piston unit 103, and then entering the third water outlet hole 72 on the other side of the cavity can be met, thereby better reflecting the ingenuity of the design of the present application; as mentioned above, the interval between the two sealing plugs 3 can be adjusted, thereby meeting different needs.

[0038] In the present application, the positions of the water inlet hole and the water outlet hole are preferably arranged, but other positions are not excluded, the core point is to meet the needs of the water channel to arrange, similarly, the number of piston units is also arranged according to the different water channels, for example, if water is supplied from the first piston unit, water is also needed to be discharged from the first piston unit, and then to the outside circulation, such as preparing soft water, dissolving salt and the like, and then entering other piston units after the outside circulation, so as to realize the stability of the full-automatic water treatment control valve of the present application, and the water channels do not interfere with each other, the precision is higher, the action is simpler, the maintenance cost is lower, the sealing of the water channel is better, and various external functions can be realized, such as adding detection instruments; the present application uses multiple plungers to move in multiple cavity positions to realize water channel switching in running and regeneration modes to realize corresponding functions (running, water replenishment, salt absorption, backwashing or forward washing), solve the problems of long stroke, too many parts, water leakage during cleaning, complex assembly in the existing transmission mechanism, and can realize precise positioning and large-scale automatic production.

[0039] As described above, the present application can realize functions by combining multiple plungers in multiple separate cavities, more plungers are protected to form more functions by combining more cavities, a transmission device is used to drive multiple plungers to move in the cavities, and a fluidic device 15 is integrated on the structure of the present application to realize water replenishment, salt absorption, and entering the resin layer through a separate salt water channel, and a three-way valve is installed at the water inlet to realize bypass, water source cutoff and forward washing functions, and a two-way electromagnetic valve (electric ball valve) can be installed at the water outlet to realize automatic closing.

[0040] It should be noted that the water channel switching plunger provided by the present application is used to replace the traditional single piston mode, can realize the switching of multiple water channels, and has higher precision, that is, three piston units 1 can be provided, each piston unit 1 is provided with a sealing plug, and a water channel is formed between adjacent sealing plugs, then the water channel structure can be changed by moving the piston unit 1, in the present application, the water inlet pipe and the water outlet pipe can be connected or disconnected according to needs, different water inlet holes or water outlet holes are opened on the shell to realize the connection and outflow of different water channels, further, the switching of different water channels can be realized by moving the piston unit 1, for example, as described above, when water flows in from one side, if the water outlet channel needs to be changed, the piston unit 1 needs to be moved, for example, if there are two water outlets on the other side, the water inlet channel can be selected, which is realized by the adjacent two sealing plugs on the piston unit 1, for example, when the water channel formed by the adjacent two sealing plugs is connected with one water outlet pipe, the water channel entering the piston unit 1 can be changed by moving the piston unit 1, so that water can be discharged from another water inlet or water outlet, and other functions can also be realized by this method.

[0041] As a further improvement, the piston unit is provided with a corresponding sealing plug according to the waterway, and the number of sealing plugs and compartments can be set as needed, and the number of sealing rings of the sealing plug can also be set. Compared with the single plunger of the traditional soft water valve which needs to stay in multiple positions, the combination of multiple plungers and multiple cavities of the soft water valve of the technical solution only needs 3 positions to realize the necessary functions (operation, salt absorption, water replenishment, backwashing, forward washing), thereby simplifying the structure of the valve body and the valve core assembly, shortening the running distance of the plunger, reducing the stay positions, and further reducing the manufacturing precision requirement and the motion control precision requirement, and reducing the failure rate. And by dividing the structure, the waterway is set separately, so that the soft water valve has great improvement in production assembly, cost control, maintainability and reliability, etc.
