The control method of the dishwasher provided by the application can be applied to the dishwasher with the capacitive deionization type water softening device. The dishwasher may include a water softening device, a washing chamber, a drain pipe, a communication valve (such as a three-way valve), an on-off valve, and the like. The water softening device and the washing cavity are respectively provided with a water inlet and a water outlet. The communication valve may be a three-way valve including a first port, a second port, and a third port, or a multi-way valve including other ports. The first port of the communication valve is connected with the water outlet of the water softening device; and the second port of the communication valve is connected with the water inlet of the washing cavity, and the third port of the communication valve is connected with the drain pipe. By opening or closing different ports of the communication valve, communication or closing between the water softening device and the washing cavity and communication or closing between the water softening device and the drain pipe can be realized. Namely, in some working states, the communicating valve is communicated with the water outlet of the water softening device and the washing cavity of the dish washing machine; in other working states, the communicating valve is communicated with the water outlet of the water softening device and the water drainage pipe. The switch valve is connected between the washing cavity and the drain pipe, and controls the communication or closing between the switch valve and the drain pipe.
The water softening device may include first and second electrodes of opposite polarities, and operate a softening function or a regeneration function by changing the polarities of the first and second electrodes. The dishwasher is provided with a control device, such as a control circuit board. The control device is electrically connected with the water softening device, the washing device and other working components to control the other devices or components to work.
In some embodiments of the present application, please refer to fig. 1 and 2, the capacitive deionization water softener 300 includes a plurality of first electrode plates 1 and a plurality of second electrode plates 2, the plurality of first electrode plates 1 and the plurality of second electrode plates 2 are alternately arranged, a channel for water to flow through is formed between adjacent first electrode plates 1 and second electrode plates 2, and in particular, the channel can be implemented by inserting an insulating filter screen between the first electrode plates 1 and the second electrode plates 2. The insulating filter screen may be made of a material having a porous structure, and when the first electrode sheet 1 and the second electrode sheet 2 are fixed together by a certain pressure, the insulating filter screen is filled between the first electrode sheet 1 and the second electrode sheet 2, so as to form a channel for water to pass through between the first electrode sheet 1 and the second electrode sheet 2.
The first electrode plate 1 and the second electrode plate 2 can be thin graphite electrode plates or other conductive materials, the first electrode plate 1 and the second electrode plate 2 are respectively connected with the positive electrode and the negative electrode of a power supply, and therefore an electric field can be formed between the first electrode plate 1 and the second electrode plate 2.
The first electrode sheet 1 is provided with a first adsorption layer (not shown) for adsorbing cations (such as calcium and magnesium ions in water), and the second electrode sheet 2 is provided with a second adsorption layer (not shown) for adsorbing anions (such as chloride ions in water).
When the water softening device 300 is powered on, the first electrode plate 1 is connected with the negative electrode of the direct current power supply, and the second electrode plate 2 is connected with the positive electrode of the direct current power supply, at the moment, when water passes through the middle of the first electrode plate 1 and the second electrode plate 2, cations and anions in the water are respectively adsorbed on the first adsorption layer and the second adsorption layer, so that the purpose of softening the water is achieved.
After the adsorption capacities of the first adsorption layer and the second adsorption layer are saturated, the directions of the positive electrode and the negative electrode of a power supply connected with the first electrode plate 1 and the second electrode plate 2 can be changed, namely the first electrode plate 1 is connected with the positive electrode of a direct-current power supply, and the second electrode plate 2 is connected with the negative electrode of the direct-current power supply.
In some embodiments of the present application, when a forward voltage is applied between the first electrode and the second electrode, the first electrode tab 1 is connected to the negative electrode of the dc power supply, and the second electrode tab 2 is connected to the positive electrode of the dc power supply. Accordingly, when a reverse voltage is applied between the first electrode and the second electrode, the first electrode tab 1 is connected to the positive electrode of the dc power supply, and the second electrode tab 2 is connected to the negative electrode of the dc power supply.
Referring to fig. 3, and as necessary in conjunction with fig. 4 to 5, the method for controlling a dishwasher provided in the present application may include steps S101 and S103 as follows:
step S101: the trigger water softening device runs a softening function at a water inlet stage of a first working stage needing to adopt soft water for washing so as to introduce water generated by running the softening function into a washing cavity of the dish washing machine;
step S103: if the water softening device runs the softening function in the first working stage, the frequency of the water softening device running the softening function reaches a preset frequency value and/or the time of running the softening function reaches a preset time and/or the water amount generated by running the softening function reaches a preset water amount, the regeneration function is run before the water inlet stage of the second working stage needing to adopt soft water for washing.
The second working phase and the first working phase may belong to the same dishwashing process, the second working phase being the next working phase requiring soft water washing to be run after the first working phase. For example, in a dishwashing program, the second operation phase may be run immediately after the first operation phase, or there may be other operation phases between the second operation phase and the first operation phase. Of course, the second working phase and the first working phase may also belong to different dishwashing processes, for example, the first working phase is a certain working phase in a first complete dishwashing process, and the second working phase is a certain working phase in a second complete dishwashing process.
The determination of whether a certain working phase requires soft water washing may be preset based on the dishwasher program or selected by the user according to the actual situation. In hot water washing, metal cations are more likely to be converted into calcium carbonate, magnesium hydroxide, and the like which are hardly soluble than in cold water washing, and scale is likely to be formed. Thus, in some embodiments of the present application, the operation stage using the heated washing water may be determined as an operation stage requiring washing with soft water. Accordingly, whether a certain working stage needs to heat the washing water or not can be judged, and if so, the working stage can be determined to need to adopt soft water for washing.
The single dishwashing cycle of the dishwasher comprises at least one working phase, each working phase comprising a water intake phase and a washing phase. In particular, the operational phase of the dishwasher may comprise a combination of one or more of a pre-wash phase, a main wash phase and a rinse phase. Correspondingly, the prewash stage comprises a prewash water-in stage, a prewash wash stage. The main wash stage includes a main wash water intake stage and a main wash stage. The rinsing stage includes a rinsing water-in stage and a rinsing washing stage.
In some dishwasher products, a complete dishwashing cycle has only a main wash phase as a working phase. In other dishwasher products, a complete dishwashing cycle has working phases comprising a main wash phase and a rinse phase, which are carried out sequentially. In still other dishwasher products, a complete dishwashing cycle includes a pre-wash phase, a main wash phase and a rinse phase in sequence. The dishwasher having two or more of a pre-washing stage, a main-washing stage and a rinsing stage, the washing pattern of the dishwasher may include various patterns. For example, a dishwasher having a pre-wash stage and a main-wash stage may be provided with a plurality of selectable wash modes. For example, in one washing mode, a complete dishwashing cycle may include only a main wash phase. In another mode, a complete dishwashing cycle has operational phases including a main wash phase and a rinse phase. In yet another mode, a complete dishwashing cycle has operational phases including a pre-wash phase, a main wash phase, and a rinse phase. Some dishwashers also have a drying function and the like after the washing process is finished.
The washing agent can be added or not added in each working stage of the dishwasher. The dishwasher may or may not be washed with soft water in its various operating stages (e.g., tap water or water generated by the regeneration function of a water softener). Accordingly, the dishwasher may use heated washing water or non-heated washing water for each operation stage. For example, the rinse phase may include a hot water rinse phase in which the dishes are washed with hot water or a cold water rinse phase in which the dishes are washed with unheated water (e.g., tap water). The working phase with heated wash water is required, which is generally heated during the washing phase.
Some embodiments of the present application are described in the context of a single dishwashing cycle of a dishwasher, the operational phases of which include a main wash phase and a rinse phase. Wherein, the tableware is washed by adding detergent and adopting a hot water washing mode in the main washing stage. The rinsing stage is a hot water rinsing stage in which the dishes are washed with heated water. In some scenarios, the rinse stage may add a brightener or a dish polish to wash the dishes. Accordingly, the first working phase is the main wash phase. The second working phase is a hot rinse phase. The first working stage and the second working stage belong to the same dish washing process. Of course, in some embodiments, the operational phase of the dishwasher may also include an operational phase between the main wash phase and the hot rinse phase, in which no heating of the wash water is required, such as an operational phase in which the dishware can be washed directly with tap water.
In step S101, the first port and the second port of the communication valve may be opened, such that the water outlet of the water softening device is connected with the water inlet of the washing chamber, such that water generated by the operation of the water softening device with the softening function is introduced into the washing chamber of the dishwasher.
Optionally, referring to fig. 4, after step S101 and before step S103, the method may include step S102: and judging whether at least one of the times of operating the softening function, the time length of operating the softening function and the water quantity generated by operating the softening function of the water softening device reaches a corresponding preset value after the water softening device operates the softening function in the first working stage. For example, whether the number of times the softening function is performed reaches a preset number of times. Whether the time length for operating the softening function reaches the preset time length or not. Whether the amount of water generated by the operation of the softening function reaches a preset amount of water.
The number of times the softening function is run is herein understood to be the number of times the softening function is run since the water softening capacity of the water softening device has been fully restored. In specific implementation, the preset times of the operation softening function can be preset according to specific conditions such as the softening capacity of the water softening device, the softening water quantity required in the working stage of the dishwasher and the like. The preset time for operating the softening function of the water softening device can be preset according to the specific conditions such as the softening capacity of the water softening device. The preset amount of water produced by the water softening device operating the softening function may also be preset according to the specific circumstances, such as the softening capacity of the water softening device.
In some embodiments, the preset number of times the water softening device is operated (i.e., the preset value corresponding to the number of times the water softening device is operated to perform the softening function) may be 1. In this way, after the end of the operation of the softening function in the first operating phase, i.e. when the predetermined number of times is reached, the regeneration function is operated before the next second operating phase in which softened water is to be used. Of course, in other embodiments, the preset number value may also be other numbers, such as 2, 3, and the like, which is not limited in this application.
In some embodiments, the number of times the water softener is operated to perform the softening function is increased by 1 after the water inlet phase of the working phase employing soft water washing is finished.
For example, after the water inlet phase of the first working phase is finished, 1 may be added to the number of times the water softener has been operated. Accordingly, for the water softener to operate the regeneration function before the water inlet stage of the second operation stage of washing with soft water, the control method of the dishwasher may include: and after the water softening device operates the regeneration function, clearing the frequency of the water softening device operating the softening function. So that the number of times the water softening device runs the softening function is counted again when the water softening device reactivates the softening function.
In some embodiments, the amount of water produced by operating the softening function may be obtained by detecting the amount of water in the washing chamber. For embodiments in which the water softening device is operable a plurality of times (e.g., a predetermined number of times is 2 or more), from the time the water softening device is operating the water softening function for the second time, the amount of water produced by each previous operation of the water softening function is added to the amount of water in the washing chamber at the time the softening function is currently operating, to obtain the amount of water produced by the operation of the water softening function. For example, for a water softening device with a preset sub-value of 3, when the water softening device operates the softening function at the 2 nd time, the generated water amount is the sum of the water amount generated by the softening function at the 2 nd time and the water amount generated by the softening function at the 1 st time.
Of course, in some embodiments, the step S102 may not be executed, and the step S103 may be directly executed when one of the number of times of operating the softening function, the time period of operating the softening function, and the amount of water generated by operating the softening function satisfies a preset value.
In step S103, the water softening device is controlled to operate the regeneration function before the water inlet stage of the next second working stage requiring soft water washing, and in a specific implementation, the regeneration function can be implemented by the following step S1031:
step S1031: controlling the water softening device to operate a regeneration function during at least part of the operation time of the washing phase of the first operation phase.
By performing the washing in the manner of step S1031, the operation time of the dishwasher can be reduced, and the operation efficiency of the dishwasher can be improved.
In some embodiments, for example, in which the second operating phase is an operating phase immediately following the first operating phase, the regeneration function of the controllable water softening device is operated in parallel with the washing phase of the first operating phase. For example, the regeneration function of the water softening device may be controlled to start operating in synchronism with the washing phase of the first operating phase. The regeneration function of the water softening device can also be controlled to end in synchronism with the washing phase of the first operating phase, although it can also be controlled to coincide with any time interval during which the two are operated. The time required for the water softening device to operate the regeneration function, the time required for the dishwasher to operate the washing stage of the first operation stage, and the like can be set specifically, but the present application does not limit the time.
It should be noted that, for the embodiment that the washing stage of the first operation stage is finished and the water softening device is not operated, the control method of the dishwasher may further include the following steps:
the water softening device is controlled to discharge the water generated by the operation of the regeneration function through a drain pipe to avoid affecting the operation of the washing stage of the first operation stage.
Of course, in some embodiments, a regeneration water tank may be provided in the dishwasher to allow the water softener to pass excess water generated by the operation of the regeneration function into the regeneration water tank for use during periods of operation where soft water washing is not required to conserve water resources. Specifically, the water outlet of the water softening device can be respectively connected with the washing cavity of the dish washing machine and the water inlet of the regeneration water tank through devices such as a three-way valve, namely, under some working states, the three-way valve is communicated with the water outlet of the water softening device and the washing cavity of the dish washing machine, and under other working states, the three-way valve is communicated with the water outlet of the water softening device and the water inlet of the regeneration water tank. The water outlet of the regeneration water tank and the washing cavity can be controlled to be in a conducting state through a switch valve. And, in combination with the function of storing the regenerated water of the regenerated water tank, the regeneration time of the water softening device can have more freedom. And, the water softening installation can be designed great than the water outlet flow of regeneration water tank to regeneration water tank's water outlet flow can realize that it is long when the intaking of shorter dish washer, thereby is favorable to shortening whole time of washing dishes.
Further, in some embodiments, there are additional phases of operation between the second phase of operation and the first phase of operation. After step S101 or step S102, the method may comprise the following step S104:
in step S104: and running a regeneration function in the water inlet stage of the third working stage, and introducing water generated by running the regeneration function into a washing cavity of the dish washing machine.
The operation mode of step S104 can effectively utilize the water with high hardness generated by the regeneration function of the water softening device, thereby reducing the waste of water resources.
Of course, in some embodiments, the water produced by the water softener during its regeneration function may also be drained through a drain, and the third stage may use water that is not treated by the water softener, such as tap water.
In some embodiments, the water outlet of the water softening device and the washing chamber and the water outlet of the water softening device and the drain pipe may be in communication via a pipe. For example, valves may be provided at the water inlet of the washing chamber and the water inlet of the drain pipe, or in the pipe or at the water outlet of the water softening device, so that the opening or closing of the pipe between the water outlet of the water softening device and the washing chamber, and the opening or closing of the pipe between the water outlet of the water softening device and the drain pipe may be controlled by controlling the opening and closing of the valves. Correspondingly, when the washing stage to be operated of the dishwasher is determined to be the pre-washing stage, the pipeline between the water outlet of the water softening device and the washing chamber can be opened and the pipeline between the water outlet of the water softening device and the drain pipe can be closed through the control valve, so that water generated by the water softening device with the regeneration function can flow into the washing chamber of the dishwasher. In addition, the water generated by the water softening device during the operation of the softening function needs to enter the washing chamber, and the water softening device can be implemented by a similar method, which is not described herein again.
In other embodiments, the water outlet of the water softener, the washing chamber and the drain pipe can be connected in series through pipelines. Namely, the water outlet of the water softening device is communicated with the water drainage pipe through the washing cavity. Valves can be arranged at the water inlet of the washing cavity and the water inlet of the water discharge pipe, or in the pipeline or at the water outlet of the water softening device, so that the opening or closing between the water outlet of the water softening device and the washing cavity and the opening or closing of the pipeline between the water outlet of the washing cavity and the water discharge pipe can be controlled by controlling the opening and closing of the valves. Correspondingly, when the washing stage to be operated of the dishwasher is determined to be the pre-washing stage, the pipeline between the water outlet of the water softening device and the washing cavity can be opened through the control valve, and the pipeline between the water outlet of the washing cavity and the water drainage pipe is closed, so that water generated by the water softening device with the regeneration function can flow into the washing cavity of the dishwasher. When the water is drained, the pipeline between the water outlet of the washing cavity and the drain pipe is opened, so that the water in the washing cavity of the dish-washing machine is drained from the drain pipe. The water generated by the water softening device during the operation of the softening function can be introduced into the washing chamber by a similar method, which is not described herein.
Further, in some embodiments, before step S104, the control method may further include step S105 of:
judging whether a third working phase which does not need to adopt soft water washing exists between the first working phase and the second working phase, and executing a step S104 if the result of the step S105 is yes; otherwise, step S103 may be performed, such as step S1031.
Further, in some embodiments, the first and second phases are different dishwashing processes. For example, the washing stage corresponding to the first working stage is the last washing stage of a single dish washing process, and the step of controlling the water softening device to operate the regeneration function before the water inlet stage of the next second working stage requiring soft water washing can be realized by the following steps S1035 and S1036:
step S1035: controlling the water softening device not to run the regeneration function before the dish washing process is finished.
Step S1036: and after the beginning of the next dish washing process is detected, controlling the water softening device to operate the regeneration function before the water inlet stage of the second working stage which needs to adopt soft water for washing and corresponds to the next dish washing process.
For example, in some embodiments, a single dishwashing cycle of a dishwasher includes a pre-wash phase, a main wash phase, and a rinse phase. Wherein, the main washing stage and the rinsing stage need to adopt soft water for washing, and the prewashing stage can not adopt soft water for washing. And after the water inlet stage of the rinsing stage, if at least one of the times of operating the softening function, the time length of operating the softening function and the water volume generated by operating the softening function reaches a corresponding preset value, controlling the water softening device of the dishwasher not to operate the regeneration function before the end of the dish washing process. Such a water softening device comprising a pre-wash phase, a main wash phase and a rinse phase is still used for the next dishwashing process, and the water softening device of the dishwasher can be controlled to perform a regeneration function before or during the next pre-wash phase. Wherein, the regenerated water with larger hardness generated by the regeneration function before the prewashing stage can be introduced into the washing cavity as the washing water of the prewashing stage.
In some embodiments, a dishwasher employing the above water softening device may have the water softening device only satisfy one washing stage per softened water. A single dishwashing process for a dishwasher comprises a pre-wash stage, a main wash stage and a rinse stage, and wherein the pre-wash stage, the main wash stage and the rinse stage are all washed with soft water. As may be seen in connection with fig. 6. In the embodiment shown in fig. 6, the water softening device operates the softening function at the water inlet stage of the pre-washing stage, the main-washing stage and the rinsing stage of the dishwasher, and introduces the water generated by the operation of the softening function into the washing chamber, and operates the regeneration function at the washing stages of the pre-washing stage, the main-washing stage and the rinsing stage, thereby effectively improving the dish washing efficiency of the dishwasher.
And a single dishwashing process for a dishwasher includes a pre-wash stage, a main wash stage, and a rinse stage, and wherein the main wash stage and the rinse stage are both washed with soft water, and the pre-wash stage may not be washed with soft water. Fig. 7 and 8 are combined to show a simple control method for two dishwashers, as shown in fig. 7 and 8. In the embodiment shown in fig. 7, the water softening device operates the softening function in the water inlet stage of the main wash stage and the rinse stage, and the water softening device operates the regeneration function in the water inlet stage of the pre-wash stage and the wash stage of the main wash stage.
