Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Referring to fig. 1, the water purifying apparatus provided by the present invention comprises an ionic resin filtering unit 1 and a water electrolyzing unit 8, wherein the ionic resin filtering unit 1 comprises a water inlet 2, a purified water outlet 3 and a waste liquid outlet 4, tap water can enter the ionic resin filtering unit 1 from the water inlet 2 and be filtered by an ionic resin filter element, the purified water outlet 3 is communicated with a purified water control valve 5, and the waste liquid outlet 4 is communicated with a waste liquid collecting and neutralizing container 7 through a waste liquid control valve 6; the water electrolysis unit 8 is used to electrolyze water into acid solution and alkali solution for being able to soak the ionic resin filter element of the ionic resin filter unit 1 alone.
In the water purifying apparatus, when the water purifying apparatus normally purifies water, the purified water control valve 5 is opened, the waste liquid control valve 6 is closed, tap water is introduced into the ionic resin filtering unit 1 from the water inlet 2, purified water flows out from the purified water outlet 3 after being filtered by the ionic resin filter element, when the ionic resin filter element needs to be activated after being used for a period of time, the purified water outlet 3 is closed, water is electrolyzed into an acid liquid and an alkali liquid by the water electrolyzing unit 8, the ionic resin filter element is soaked with one of the acid liquid and the alkali liquid for a predetermined time, the waste liquid control valve 6 is opened, the soaking waste liquid is discharged into the waste liquid collecting neutralization container 7 from the waste liquid outlet 4, then the waste liquid control valve 6 is closed, one of the acid liquid and the alkali liquid discharged into the waste liquid collecting neutralization container 7 is neutralized with the other of the acid liquid and the alkali liquid, for example, the other of the acid liquid and the alkali liquid can be directly discharged into the waste liquid collecting neutralization container 7 to be neutralized, or after the other of the acid liquor and the alkali liquor soaks the ionic resin filter element for a preset time, the waste liquor control valve 6 is opened, the soaking waste liquor is discharged into the waste liquor collecting and neutralizing container 7 from the waste liquor discharge port 4, the ionic resin filter element is soaked by the acid liquor and the alkali liquor respectively, the activation effect of the ionic resin filter element can be improved, and the acid liquor and the alkali liquor discharged into the waste liquor collecting and neutralizing container 7 are neutralized in the waste liquor collecting and neutralizing container 7. Therefore, the water purifying device can safely and simply complete the activation of the ion resin filter element, and no substances polluting the environment are discharged, so that the service cycle of the ion resin filter element can be prolonged, and the waste of resources is reduced.
In the water purifying apparatus, the acid solution and the alkali solution generated by electrolyzing water by the water electrolysis unit 8 can be stored in respective containers, and a user can put the acid solution or the alkali solution into the ion resin filtering unit 1 to soak. Alternatively, as shown in fig. 1, the water electrolysis unit 8 communicates with the ion resin filtration unit 1 through the first transfer passage 9, and the water electrolysis unit 8 communicates with the reservoir 11. Thus, when the ionic resin filter element needs to be activated, one of the acid liquid and the alkali liquid formed by the operation of the water electrolysis unit 8 is directly conveyed into the ionic resin filter unit 1 through the first conveying flow path 9 to soak the ionic resin filter element, while the other one of the formed acid liquid and alkali liquid is temporarily stored in the liquid storage container 11, and after one of the acid liquid and the alkali liquid is soaked and discharged into the waste liquid collecting and neutralizing container 7, the other one of the acid liquid and the alkali liquid stored in the liquid storage container 11 is neutralized in the waste liquid collecting and neutralizing container 7 and one of the acid liquid and the alkali liquid discharged into the waste liquid collecting and neutralizing container 7.
Further, as shown in fig. 1, the water electrolysis unit 8 communicates with the ion resin filtration unit 1 through a second delivery flow path 10, and the second delivery flow path 10 includes a reservoir 11. Thus, when the ionic resin filter element needs to be activated, one of the acid liquor and the alkali liquor generated by the water electrolysis of the water electrolysis unit 8 is directly conveyed into the ionic resin filter unit 1 through the first conveying flow path 9 to soak the ionic resin filter element, while the other one of the acid liquor and the alkali liquor is temporarily stored in the liquid storage container 11, when one of the acid liquor and the alkali liquor is soaked and discharged into the waste liquid collecting neutralization container 7, the other one of the acid liquor and the alkali liquor stored in the liquid storage container 11 is conveyed into the ionic resin filter unit 1 through the second conveying flow path 10 to soak the ionic resin filter element and is discharged into the waste liquid collecting neutralization container 7 after soaking is completed, and then the acid liquor and the alkali liquor are neutralized in the waste liquid collecting neutralization container 7.
In addition, in order to prevent the other one of the acid solution and the alkali solution stored in the liquid storage container 11 from entering the ion resin filter unit 1 when the ion resin filter element is soaked in the one of the acid solution and the alkali solution, as shown in fig. 1, a switch valve 12 is arranged between the liquid storage container 11 and the ion resin filter unit 1. Therefore, when one of the acid liquor and the alkali liquor soaks the ion resin filter element, the switch valve 12 is closed, so that the other one of the acid liquor and the alkali liquor cannot enter the ion resin filtering unit 1, thereby avoiding neutralizing the acid liquor or the alkali liquor soaking the ion resin filter element, and improving the activation effect of the ion resin filter element.
In addition, the acid solution or the alkali solution stored in the liquid storage container 11 can be manually stored in the ion resin filtering unit 1 by a user. Alternatively, as shown in fig. 1, the second delivery flow path 10 includes a booster pump 16, so that, by opening the on-off valve 12, the booster pump 16 can boost the acid solution or the alkali solution in the reservoir 11 to be pumped into the ion resin filtration unit 1 completely to soak the ion resin filter element. Particularly, when the water purifier purifies water, and tap water flows into the ionic resin filtration unit 1 through the water electrolysis unit 8, the first delivery flow path 9 and the second delivery flow path 10 to be filtered and purified, the booster pump 16 can pump out all acid liquor or alkali liquor stored in the liquid storage container 11, so as to prevent part of the acid liquor or alkali liquor from being mixed into the tap water, and further improve the water purification effect of purifying water again.
In addition, the connection ends of the first and second transfer flow paths 9 and 10 to the ion resin filtration unit 1 may be separated from the water inlet 2. Alternatively, as shown in fig. 1, the first and second transfer flow paths 9 and 10 are connected to the water inlet 2. In this way, during water purification, the tap water flows into the ion resin filtration unit 1 through the water electrolysis unit 8, the first transfer channel 9, and the second transfer channel 10, and is filtered and purified, and at this time, the purified water control valve 5 is opened and the waste liquid control valve 6 is closed. And when the ionic resin filter element needs to be activated, the water purification control valve 5 is closed, the water electrolysis unit 8 is started, tap water is electrolyzed to form acid liquor and alkali liquor so as to soak and activate the ionic resin filter element in the ionic resin filter unit 1, and after the soaking and activation, the acid liquor and the alkali liquor are neutralized in the waste liquid collection and neutralization container 7.
In addition, in the actual use of the water purification apparatus, a user can activate the water electrolysis unit 8 at intervals to activate the ion resin cartridge. Alternatively, the user may decide whether to activate the ion resin cartridge based on the Total Dissolved Solids (TDS) in the purified water. Therefore, as shown in fig. 1, a purified water discharge pipe section 13 is connected to the purified water discharge port 3, the purified water control valve 5 is provided on the purified water discharge pipe section 13, and a TDS detecting member 14 between the purified water control valve 5 and the purified water discharge port 3 is provided on the purified water discharge pipe section 13, so that the TDS detecting member 14 detects the TDS of the purified water discharge water in real time when purifying water, and when the TDS of the purified water falls to a predetermined value, the purified water control valve 5 can be closed, and the water electrolysis unit 8 can be activated to activate the ionic resin cartridge.
Of course, the user may manually activate the water electrolysis unit 8. Or, the water purifying apparatus includes a control unit (not shown in the figure), the control unit can receive the real-time detection value of the TDS detecting member 14 and can control the operation of the water electrolysis unit 8 when the real-time detection value is reduced to a predetermined value, and the water purification control valve 5 and the waste liquid control valve 6 are closed, so that the predetermined value can be set by the control unit according to the water quality of each place, thereby enabling the water purifying apparatus to be used in different areas and improving the convenience of use for users.
Further, as shown in fig. 1, the control unit controls the clean water control valve 5 and the waste liquid control valve 6 to be closed when the real-time detection value falls to a predetermined value. That is, the waste liquid control valve 6 may be in a closed state or an open state during water purification as long as purified water is not allowed to flow out of the waste liquid control valve 6. When the ionic resin filter core needs to be activated, the control unit controls the clean water control valve 5 and the waste liquid control valve 6 to be closed, so that the acid liquor or the alkali liquor can completely soak the ionic resin filter core and cannot flow out. This also improves the convenience of use for the user, and avoids the user from manually closing the water purification control valve 5 and the waste liquid control valve 6 by himself.
In addition, as shown in fig. 1, in order to further improve the activation effect of the ionic resin cartridge, the waste liquid discharge port 4 is connected with a pH detector 15 located between the waste liquid control valve 6 and the waste liquid discharge port 4, and the control unit can adjust the electrolysis rate of water by the water electrolysis unit 8 according to the real-time detection value of the pH detector 15 and stop the water electrolysis unit 8 after the real-time detection value reaches a set value. That is, when the acid solution or the alkali solution can completely soak the ionic resin filter element, the pH detecting element 15 can detect the pH value of the soaking solution in real time, and the control unit can adjust the electrolysis rate of the water electrolysis unit 8 to the water (for example, adjust the voltage of the water electrolysis unit 8, the flow rate of the water passing through the water electrolysis unit 8, etc.) according to the real-time detection value of the pH detecting element 15, so that the required acid solution and alkali solution can be formed more quickly to soak the ionic resin filter element more quickly.
In addition, the control unit has other functions, for example, in the solution of the water purifying apparatus including the booster pump 16, after one of the acid solution and the alkali solution soaks the ion resin filter cartridge for a predetermined time, the control unit can control the waste liquid control valve 6 to open to drain the liquid into the waste liquid collecting neutralization tank 7, and control the waste liquid control valve 6 to close after the drainage is completed, the control unit can then control the on-off valve 12 to open and control the booster pump 16 to start to transfer the other one of the acid solution and the alkali solution stored in the liquid storage tank 11 into the ion resin filtering unit 1 to soak the ion resin filter cartridge, and open the waste liquid control valve 6 to drain the ion resin filter cartridge into the waste liquid collecting neutralization tank 7 after soaking the ion resin filter cartridge for a predetermined time, that is, the water purifying and the activation of the ion resin filter cartridge of the water purifying apparatus are both automatically controlled by the control unit, therefore, the convenience of the user can be effectively improved without manual operation.
In addition, the present invention provides a method for activating an ion resin cartridge of a water purification apparatus, the method comprising: electrolyzing water to obtain acid liquor and alkali liquor, soaking the ionic resin filter element in one of the acid liquor and the alkali liquor for a preset time, and discharging the ionic resin filter element into a waste liquid collecting and neutralizing container; and neutralizing one of the acid solution and the alkali solution discharged into the waste liquid collection by using the other one of the acid solution and the alkali solution.
Therefore, when the ionic resin filter element needs to be activated, water is electrolyzed to obtain acid liquid and alkali liquid, the ionic resin filter element is soaked in one of the acid liquid and the alkali liquid for a preset time and then is discharged into a waste liquid collecting and neutralizing container, the other one of the acid liquid and the alkali liquid is used for neutralizing one of the acid liquid and the alkali liquid discharged into the waste liquid collecting and neutralizing container, the activation effect of the ionic resin filter element can be improved through the independent soaking of the acid liquid and/or the alkali liquid on the ionic resin filter element, and the acid liquid and the alkali liquid discharged into the waste liquid collecting and neutralizing container can be neutralized.
The other of the acid solution and the alkali solution can directly neutralize the soaked waste liquid, or the other of the acid solution and the alkali solution firstly soaks the ion resin filter element and then neutralizes the other of the acid solution and the alkali solution after soaking.
For example, in one embodiment, the ion resin filter element is soaked with the other of the acid solution and the alkali solution for a predetermined time and then discharged into the waste liquid collecting and neutralizing container, so that the acid solution and the alkali solution discharged into the waste liquid collecting and neutralizing container are neutralized. Therefore, the ionic resin filter element is soaked by the acid liquor and the alkali liquor respectively, and the activation effect of the ionic resin filter element can be effectively improved.
In addition, when the water purifying device is in a water purifying state, the water electrolysis unit of the water purifying device is powered off, and inlet water is supplied to the ionic resin filter element through the water electrolysis unit to be purified; after the water electrolysis unit is electrified and started, water is electrolyzed to obtain acid liquor and alkali liquor. Thus, during water purification, tap water flows into the ionic resin filtering unit through the water electrolysis unit to be filtered and purified. And when the ionic resin filter element needs to be activated, the water electrolysis unit is started, tap water is electrolyzed to form acid liquor and alkali liquor so as to soak and activate the ionic resin filter element in the ionic resin filter unit, and after the soaking and activation, the acid liquor and the alkali liquor are neutralized in a waste liquid collecting and neutralizing container.
In addition, the control unit of the water purifying device can start to operate the water electrolysis unit to electrolyze water to obtain acid liquor and alkali liquor when the real-time TDS value of the discharged purified water is reduced to a preset value, when one of the acid liquor and the alkali liquor begins to soak the ionic resin filter element, the control unit can adjust the decomposition rate of the water electrolysis unit in the starting operation state to the water according to the real-time pH value of the ionic resin filter element in the soaking state, and can control the water electrolysis unit to stop operating after the real-time pH value reaches the set value. Thus, the preset value can be set through the control unit according to the water quality of each place, when the real-time TDS value of the discharged purified water is reduced to the preset value, the control unit starts the water electrolysis unit to soak the ionic resin filter element, meanwhile, the pH detection piece can detect the pH value of the soaking liquid in real time, and the control unit can adjust the electrolysis rate of the water electrolysis unit to the water (such as adjusting the voltage of the water electrolysis unit, the flow rate of the water passing through the water electrolysis unit and the like) according to the real-time detection value of the pH detection piece, so that the required acid liquid and alkali liquid can be formed more quickly, and the ionic resin filter element can be soaked more quickly. Like this, can make this purifier can use in different areas, promote the convenience that the user used.
