The embodiment of the application provides a dishwasher-based water purification control method, a dishwasher-based water purifier, a dishwasher-based water purification system and a storage medium. Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments and features of the embodiments described below can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flow chart of a dishwasher-based water purification control method applied to a water purifier, through which a water inlet of a dishwasher is communicated with a tap water pipe, according to an embodiment of the present application, as shown in fig. 1, the dishwasher-based water purification control method specifically includes steps S101 to S103.
S101, when the dishwasher is in a working state, determining a dish washing mode of the dishwasher, and determining a first water purification mode and a second water purification mode according to the dish washing mode;
wherein, dish washer is through the clean electrical apparatus that washes the tableware in the cupboard in order to realize automatic washing dishes, and dish washer is in operating condition and the state that dish washer starts and washes dishes promptly, has multiple mode of washing dishes among the dish washer, and under the different mode of washing dishes, the chance of washing dishes adopts different flow and/or different temperature to wash the tableware. However, the dishwashing process of a dishwasher generally comprises a washing phase and a rinsing phase, and different dishwashing modes may comprise different numbers of washing phases and/or different numbers of rinsing phases.
Generally, the tableware is placed in a dish washing cabinet of a dish washing machine, washings are added and clean water is injected, a dish washing barrel mixes the clean water and the washings through mechanical force, the clean water mixed with the washings is used for washing the tableware, the function of washing the tableware in the barrel is further realized, and after washing is finished, the dish washing machine can inject the clean water again to wash the residual washings in the tableware until the washings in the tableware are washed clean.
The washing stage is a process of washing the dishes by mixing the washings and clean water through the dish washing machine and washing the dishes with the water containing the washings, and the rinsing stage is a process of removing the residual washings on the dishes through the clean water through the dish washing machine. Different dishwashing modes of a dishwasher generally comprise at least one washing phase and at least one rinsing phase, the washing phase being carried out first and the rinsing phase being carried out after the washing phase. The laundry may be a detergent, a washing block or other washing material.
The dishwashing mode includes specific phases corresponding to the type of dishwashing mode selected by the user, for example, a one-wash phase and a two-rinse phase if the user selects the standard dishwashing mode, and a one-wash phase and a one-rinse phase if the user selects the fast dishwashing mode.
Establish communication connection between water purifier and the dish washer, dish washer can be when starting entering operating condition, will include the information transmission of the mode of washing dishes of dish washer to the water purifier, and the water purifier can be according to the mode of washing dishes of the information determination dish washer of acquireing.
Under the different mode of washing dishes, the requirement of dish washer to quality of water is different, consequently after the mode of washing dishes of confirming dish washer, according to first water purification mode and second water purification mode are confirmed to the mode of washing dishes to subsequent dish washer is when carrying out washing stage and rinsing stage, can come to handle the running water according to first water purification mode and the second water purification mode that confirm well. For example, if the dishwashing mode is the standard dishwashing mode, the default secondary water purification level may be determined as the first water purification mode, and the default primary water purification level may be determined as the second water purification mode.
In one embodiment, the determining of the first and second water purification modes according to the dish washing mode may be performed by:
determining the water temperature of the dishwasher according to the dish washing mode; and determining the water purification level of the first water purification mode according to the water temperature, and determining the water purification level of the second water purification mode.
The dish washer generally adopts the heated water to wash the tableware, and in the process of heating the tap water, partial chemical substances in the tap water can be naturally removed. The dishwasher adopts different dish washing modes, the adopted water temperature is different, for example, when the water temperature is higher, most chemical substances in tap water can be removed, and then the tap water can be treated by adopting a lower water purification level, and when the water temperature is lower, a small part of chemical substances in the tap water can be removed, and a certain water purification level is still needed for treating the tap water.
Accordingly, after the water temperature of the dishwasher is determined according to the dish washing mode, the water purification level of the first water purification mode may be determined according to the water temperature, and the water purification level of the second water purification mode may be determined. Exemplarily, if the water temperature is lower than the preset temperature, the default secondary water purification level is adopted as the first water purification mode, and the default primary water purification level is adopted as the second water purification mode; and if the water temperature is higher than the preset temperature, adopting a default three-stage water purification grade as a first water purification mode, and adopting a default two-stage water purification grade as a second water purification mode.
S102, if the dishwasher is in a washing stage, controlling the water purifier to treat tap water in a first water purification mode.
S103, if the mode of washing the dishes includes a rinsing stage just the dish washer is in the rinsing stage, or if the mode of washing the dishes includes a rinsing stage many times just the dish washer is in the rinsing stage of last time, then control the water purifier adopts second water purification mode to handle the running water, wherein, the water purification rank of second water purification mode is higher than first water purification mode.
The requirements of the dishwasher on water quality are different between a washing stage and a rinsing stage, the dishwasher mixes washings and clean water to wash dishes in the washing stage, the washings contain more chemical substances to remove stains on the dishes, therefore, the clean water in the dishwasher is polluted in the washing stage, and partial substances in tap water can be allowed in the washing stage. Accordingly, the water purifier may be controlled to treat the tap water at a moderate water purification level, i.e., by the first water purification mode, in which the water purifier may filter solid particles in the tap water, but part of the chemical substances may not be filtered, and part of the chemical substances may be salt ions, etc.
In the rinsing stage of the tableware, especially in the last rinsing stage, the detergent and other substances remained in the tableware need to be discharged, and if chemical substances still exist in tap water, the chemical substances remain on the tableware, so that the tableware cannot be cleaned, and the tableware is harmful to human bodies in the past. Therefore, when the dishwasher is in the rinsing stage, tap water having a high purification rate is required so that the dishes can be thoroughly washed.
If the dish washing mode includes a primary rinsing stage, the water purifier is controlled to treat the tap water directly in the rinsing stage by using the second water purification mode, so that most of the substances in the tap water can be removed, and the tableware is rinsed by using the tap water with a high purification rate. And if the dish washing mode includes a plurality of rinsing stages, the water purifier may be controlled to treat the tap water using the second water purification mode so that most of the substances in the tap water can be removed and the dishes are rinsed using the tap water having a high purification rate in the last rinsing stage of the plurality of rinsing stages.
The second water purification mode has a higher water purification level than the first water purification mode, and for example, the water purifier can filter out solid particles and most chemical substances in tap water, wherein most chemical substances include salt ions and the like.
The water purifier realizes the concrete realization of first water purification mode and second water purification mode, can come different operations according to the water purification principle of different grade type. For example, if the water purifier purifies the tap water and the tap water needs to flow through the filter assembly in a circulating manner for multiple times to gradually purify the tap water, different purification degrees can be controlled by setting the circulating times of the tap water to realize the first water purification mode and the second water purification mode.
In one embodiment, the first water purification mode includes: detecting the conductivity of tap water at the water outlet of the filter assembly, if the conductivity does not reach the first conductivity, controlling the valve assembly to guide the tap water at the water outlet of the filter assembly to the water inlet of the filter assembly so that the tap water at the water outlet of the filter assembly can flow through the filter assembly again to be purified, and if the conductivity reaches the first conductivity, controlling the valve assembly to guide the tap water at the water outlet of the filter assembly to the water inlet of the dishwasher.
The second water purification mode includes: detecting the conductivity of tap water at the water outlet of the filter assembly, if the conductivity does not reach a second conductivity, controlling the valve assembly to guide the tap water at the water outlet of the filter assembly to the water inlet of the filter assembly so that the tap water at the water outlet of the filter assembly can flow through the filter assembly again to be purified, and if the conductivity reaches the second conductivity, controlling the valve assembly to guide the tap water at the water outlet of the filter assembly to the water inlet of the dishwasher; the second conductivity is lower than the first conductivity, the first conductivity corresponds to the water purification requirement of the first water purification mode, the second conductivity corresponds to the water purification requirement of the second water purification mode, and the lower the conductivity is, the higher the water purification level of the tap water is.
In one embodiment, the method further comprises the operations of:
and if the dish washing mode comprises a plurality of rinsing stages and the dish washing machine is in the previous rinsing stage, controlling the water purifier to treat tap water through a third water purification mode, wherein the water purification level of the third water purification mode is lower than that of the first water purification mode.
The water purification control method based on the dish washing machine, disclosed by the embodiment of the application, can enable the water purifier to adopt different water purification modes to treat tap water according to different dish washing modes of the dish washing machine, so that the water purification level of the water purifier is reduced in the stage that the dish washing machine does not need too high water purification level, the utilization rate of the filter assembly can be reduced while the dish washing effect is not influenced, and the service life of the filter assembly in the water purifier configured by the dish washing machine can be further prolonged.
Wherein, if the dishwashing mode includes a plurality of rinsing stages, the previous rinsing stage is all rinsing stages before the last rinsing stage, for example, if the dishwashing mode includes two rinsing stages, the previous rinsing stage is the first rinsing stage, and if the dishwashing mode includes three rinsing stages, the previous rinsing stage is the first rinsing stage and the second rinsing stage. The previous rinsing stage is a stage of diluting the washing material in the dishes passed through the washing stage and discharging the sewage water in which the washing material is diluted. And the last rinsing stage is still arranged after the previous rinsing stage, so that the requirement on water quality in the previous rinsing stage is low, and tap water can be treated by adopting a lower water purification grade. Adopt the third water purification mode to handle the running water promptly, the water purification rank of third water purification mode is less than the water purification rank of first water purification mode, and the concrete realization of third water purification mode can refer to the realization principle about first water purification mode and second water purification mode above, and it is no longer repeated here.
In one embodiment, the method further comprises the operations of:
if the dish washing mode comprises a plurality of rinsing stages and the dish washing machine is in the previous rinsing stage, the water purifier is controlled to stop treating the tap water or to release waste substances.
When the dishwasher is in the previous rinsing stage, the water purifier can be controlled to stop treating the tap water, namely the tap water is not subjected to purification treatment, and the conventional tap water is adopted to dilute the washing substances on the tableware. Or the water purifier can be controlled to release the waste materials, so that the waste materials of the water purifier can enter the dishwasher along with the tap water and can be discharged along with the sewage in the dishwasher.
In one embodiment, the controlling of the water purifier to release the waste material may be performed by:
the control power supply assembly applies a reverse voltage to the filter assembly of the water purifier to cause the filter assembly to release the waste materials into the tap water.
Wherein, the filter component that the water purifier adopted can be single flow path desalination subassembly, and single flow path desalination subassembly can include physical adsorption desalination filter core and/or chemical adsorption desalination filter core. Illustratively, the chemisorptive desalination cartridge can include at least one of an ion exchange (IX) resin cartridge, a bipolar membrane (Biopolar, BP) desalination cartridge. Exemplary, the physisorption desalination filter element may include at least one of a Capacitive Desalination (CDI) filter element, a Membrane Capacitive Desalination (MCDI) filter element. Specifically, the capacitive desalination filter element, the membrane capacitive desalination filter element, the bipolar membrane electrodeionization filter element and the like can cause the directional migration of cations and anions when being electrified so as to realize the purification treatment of water, and the filter elements can be called as electrically driven desalination filter elements.
Fig. 2 and 3 show a schematic diagram of a bipolar membrane electrodeionization filter cartridge 900. The bipolar membrane electrodeionization filter cartridge 900 includes one or more pairs of electrodes 910, and at least one pair of electrodes 910 has a bipolar membrane 920 or a plurality of spaced bipolar membranes 920 disposed therebetween. Wherein, bipolar membrane 920 includes cation exchange membrane 921 and anion exchange membrane 922, and cation exchange membrane 921 and anion exchange membrane 922 set up relatively, compound together. For example, the bipolar membrane 920 can be produced by a hot press molding method, a bonding molding method, a casting molding method, an anion and cation exchange radical method, an electrodeposition molding method, or the like. Specifically, there is no space between the cation exchange membrane 921 and the anion exchange membrane 922 on one bipolar membrane 920, for example, water does not pass between the cation exchange membrane 921 and the anion exchange membrane 922 on the same bipolar membrane 920 when flowing through the bipolar membrane electrodeionization filter cartridge 900.
As shown in fig. 2 and 3, the pair of electrodes 910 includes a first electrode 911 and a second electrode 912, wherein the first electrode 911 is disposed opposite to a cation exchange membrane 921 of the bipolar membrane 920 adjacent to the first electrode 911, and the second electrode 912 is disposed opposite to an anion exchange membrane 922 of the bipolar membrane 920 adjacent to the second electrode 912.
Fig. 2 is a schematic diagram showing the operation principle of the bipolar membrane electrodeionization filter element 900 in the process of purifying water. Here, the potential of the first electrode 911 is higher than that of the second electrode 912, that is, a voltage in a forward direction is applied between the first electrode 911 and the second electrode 912. At this time, anions such as chloride ions in the raw water to be purified move towards the first electrode 911, and replace OH < - > in the anion exchange membrane 922 in the direction of the first electrode 911, and the OH < - > enters the flow channel between the adjacent bipolar membranes 920; meanwhile, cations such as Na + in the raw water move towards the second electrode 912 to replace H + in the cation exchange membrane 921 in the direction of the second electrode 912, and the H + enters the flow channel; h + and OH-are subjected to neutralization reaction in the flow channel to generate water, so that the salt in the raw water is removed, and purified pure water flows out from the tail end of the flow channel.
As shown in fig. 3, when a voltage in opposite directions is applied between the first electrode 911 and the second electrode 912, so that the potential of the first electrode 911 is lower than that of the second electrode 912, OH "and H + ions are generated on the surfaces of the cation exchange membrane 921 and the anion exchange membrane 922 of the bipolar membrane 920 under the action of an electric field, cations such as Na + inside the cation exchange membrane 921 are replaced by H + ions and move toward the first electrode 911 with a low potential, anions such as chloride ions inside the anion exchange membrane 922 are replaced by OH" and move toward the second electrode 912 with a high potential, and the cations such as Na + and the anions such as chloride ions enter the flow channel and can be washed out by the water flowing through the bipolar membrane electrodeionization filter 900. Therefore, when the power is off or reverse voltage is applied to the desalting filter cores such as the bipolar membrane electrodeionization filter core 900 and the like, cations such as Na < + >, anions such as chloride ions and the like adsorbed on the bipolar membrane 920 are released, so that salt substances in the desalting filter core can be washed out by water to realize regeneration; water carrying cations such as Na + and anions such as chloride ions can be called concentrated water.
Therefore, by applying a forward voltage to the filter element, the filter element is caused to adsorb substances in the tap water; and applying a reverse voltage to the filter assembly to cause the filter assembly to release the absorbed waste material, wherein the waste material can enter the dishwasher along with the tap water and be discharged along with the sewage in the dishwasher. Similarly, the water purifier can stop processing the tap water by stopping applying the voltage to the filter assembly.
In one embodiment, the controlling the water purifier to release the waste material further comprises the operations of: a control valve assembly directs tap water to the waste area.
Wherein, still be provided with the valve module in the water purifier, after control filter assembly released waste material, can lead the running water that contains waste material to the waste water area. The waste area may be a waste tank, or a drain in a household. In the case of a relatively concentrated waste, tap water containing the waste is discharged to a waste water area, so that the tableware in the dishwasher can be prevented from being contaminated.
The valve assembly can be arranged at the water outlet of the water purifier, and tap water in the water purifier can be guided to a waste water area or to the water inlet of the dish washing machine by controlling the valve assembly. The structure of the valve assembly can refer to the valve structure in the prior art, and is not limited herein.
In one embodiment, the controlling the water purifier to treat tap water in the first water purification mode may be performed by:
controlling a power supply assembly to apply a first forward voltage to a filter assembly of the water purifier so that the filter assembly adsorbs substances in tap water at a first power;
control the water purifier adopts the second water purification mode to handle the running water, include:
controlling a power supply assembly to apply a second forward voltage to a filter assembly of the water purifier so that the filter assembly adsorbs substances in tap water at a second power; wherein the second forward voltage is greater than the first forward voltage, and the second power is greater than the first power.
Wherein, can make the filter assembly work with different powers through exerting different voltages on the filter assembly of water purifier, can adsorb the material of different volumes in the running water. The higher the applied voltage, the more powerful the filter assembly is to operate, and more material can be adsorbed. The purification level of the water purifier can be made higher by applying the second voltage larger, and the purification level of the water purifier can be made lower by applying the first voltage smaller, and thus the water purifier can realize the first and second water purification modes, respectively.
Referring to fig. 4, fig. 4 is a schematic block diagram of a water purifier according to an embodiment of the present application.
Referring to fig. 4, the water purifier 100 includes a processor 110 and a memory 120 connected by a system bus, wherein the memory 120 may include a nonvolatile storage medium and an internal memory.
The non-volatile storage medium may store an operating system and a computer program. The computer program comprises program instructions which, when executed, cause the processor to perform any one of the dishwasher-based water purification control methods.
