Technical Field
The application relates to a water softening control method of a dish washing machine, the dish washing machine, water softening equipment and a storage medium in the technical field of dish washing machines.
Background
The washing water in the household dish washer is generally directly connected to tap water as a washing water source, the tap water contains a large amount of metal ions and the like, and when the non-softened washing water is used for a long time to wash tableware, water scales are easily accumulated on the positions of a water spraying arm, an inner container and the like of the dish washer, so that the water spraying hole of the dish washer is blocked, the washing effect is influenced and the like. Therefore, a resin water softener is usually arranged in the dishwasher, sodium ions in the resin water softener can exchange with calcium and magnesium ions in tap water after tap water flows into the resin water softener, and softened water after the calcium and magnesium ions are removed enters the dishwasher body to wash dishes, so that the generation of scale is reduced or prevented.
However, the resin water softener needs to be washed and regenerated by salt water (by using sodium ions in salt to exchange calcium and magnesium ions absorbed by the resin), and the salt is consumed each time the salt water is washed and regenerated, so after the dishwasher is used for a period of time, the salt is manually added to the water softener to ensure the softening effect. Because the water quality is different in different regions throughout the country and it is not practical to set different resin regeneration logics for different cities in different regions, the dishwasher is generally regenerated after a fixed cumulative amount of water intake or the number of times of water intake. This causes a delay in the regeneration of the resin at a place where the water hardness is high, resulting in an unsatisfactory softening effect.

Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a dishwasher 100 according to an embodiment of the present application. The dishwasher 100 includes a dishwasher body 110, an electronic water softener 120, a first pipe 130, a second pipe 140, a third pipe 150, a hardness detecting device 160, a multi-way valve 170, and a controller 180. The electronic water softener 120 is provided on the second pipe 140. The first pipe 130 is used for communicating with an external water source. The first pipe 130 may selectively communicate with one end of the second pipe 140 or one end of the third pipe 150. The other end of the second pipe 140 and the other end of the third pipe 150 are both communicated with the dishwasher body 110. Specifically, the first pipe 130 is used to guide an external water source. The second pipe 140 communicates with the dishwasher body 110. The electronic water softener 120 is provided on the second pipe 140 to soften the washing water flowing through the electronic water softener 120. The other end of the third pipe 150 communicates with the outlet end of the electronic water softener 120. The external water source can enter the dishwasher body 110 through the first and second pipes 130 and 140, or through the first and third pipes 130 and 150 to wash dishes in the dishwasher 100. Wherein the external water source flowing through the second pipe 140 or the third pipe 150 is the washing water.
In some embodiments, the first pipe 130 may selectively communicate with one end of the second pipe 140 or one end of the third pipe 150. When the first pipe 130 is communicated with the second pipe 140, the external water enters the dishwasher body 110 from the first pipe 130 and the second pipe 140 to wash dishes. When the external water source flows through the electronic water softener 120 on the second pipeline 140, the electronic water softener 120 can soften the external water source, so as to reduce or avoid the generation of scale in the dishwasher body 110, improve the washing effect and provide a guarantee for the normal operation of the dishwasher 100. When the first pipe 130 is communicated with the third pipe 150, an external water source may enter the dishwasher body 110 through the first pipe 130 and the third pipe 150 to wash dishes. Specifically, when the hardness value of the water at the inlet end of the electronic water softener 120 is relatively small, the external water source can enter the dishwasher body without being softened by the electronic water softener 120, so that the soft water frequency of the electronic water softener 120 is reduced, and the burden of the electronic water softener 120 is reduced.
In some embodiments, the electronic water softener 120 and the hardness detecting device 160 are electrically connected to the controller 180. The hardness detecting device 160 is disposed on the first pipeline 130, and is used for detecting a water hardness value corresponding to the inlet end of the electronic water softener 120. The dishwasher 100 can determine a preset water softening condition according to a water quality hardness value corresponding to the inlet end of the electronic water softener 120; and softening the washing water flowing through the electronic water softener according to the water softening mode corresponding to the preset water softening condition. Different preset water softening conditions correspond to different water softening modes. So, different water softening modes can be confirmed according to different water hardness values to dish washer 100 to adjust soft water ability, guarantee the soft water effect, and can be applicable to the area that the water hardness value is different, improved dish washer 100's adaptability.
When the hardness value of the water flowing into the first pipe 130 is greater than or equal to a certain value, the controller 180 controls the first pipe 130 to communicate with the second pipe 140, and the washing water is softened by the water softener 120 on the second pipe 140 and then enters the dishwasher body 110 to wash dishes. And, when the water hardness values are different, the corresponding soft water modes may be different, thereby adjusting the soft water capacity, ensuring the soft water effect and improving the adaptability of the dishwasher 100.
The hardness detection device 160 may be designed into any suitable hardness detection structure according to actual requirements, such as a hardness sensor.
In some embodiments, the preset water softening conditions include a first water softening condition, a second water softening condition, and a third water softening condition. The first water softening conditions include: the water quality hardness value is greater than or equal to the first hardness threshold value and is less than the second hardness threshold value. The second water softening conditions include: the water quality hardness value is greater than or equal to the second hardness threshold and is less than a third hardness threshold. The third water softening condition comprises: the water quality hardness value is greater than or equal to the third hardness threshold value.
The first hardness threshold, the second hardness threshold and the third hardness threshold can be set according to actual requirements, for example, the first hardness threshold is 0-80PPM, that is, 0PPM, 50PPM, 80PPM and any other suitable value in 0-80 PPM. The second hardness threshold is 81PPM-300PPM, i.e., 81PPM, 200PPM, 300PPM, or any other suitable value from 81PPM-300 PPM. The third hardness threshold is 301PPM-600PPM, i.e. 301PPM, 500PPM, 600PPM and any other suitable value from 301PPM-600 PPM.
In some embodiments, the first, second and third water softening conditions correspond to a first, second and third water softening regime, respectively. The first water softening mode is as follows: the voltage of the electronic water softener is a first voltage. The second water softening mode is as follows: the voltage of the electronic water softener is a second voltage. The third water softening mode is as follows: the voltage of the electronic water softener is a third voltage. Wherein the third voltage is greater than the second voltage, which is greater than the first voltage. Thus, the controller 180 can control the voltage of the electrode of the electronic water softener 120 according to the water quality hardness value, so that the dishwasher 100 can ensure the soft water effect at the place where the water quality hardness value is lower, and the adaptability of the dishwasher 100 is improved.
The first voltage, the second voltage and the third voltage can be designed to be any suitable values according to actual requirements. Illustratively, the first voltage is 0V-12V, i.e., any one of 0V, 12V, and 0 to 12V. The second voltage is 12V-24V, i.e., any one of 0V, 12V, and 0 to 12V. High voltage range: 24V-36V, i.e. any of 0V, 12V and 0 to 12V.
In some embodiments, the multi-way valve 170 has a first port, a second port, and a third port. The first, second and third ports are connected to the first, second and third pipelines 130, 140 and 150, respectively. Specifically, a first port of the multi-way valve 170 communicates with the first pipe 130, a second port of the multi-way valve 170 communicates with the second pipe 140, and a third port of the multi-way valve 170 communicates with the third pipe 150. When the first and second ports of the multi-way valve 170 are communicated, the first and second pipes 130 and 140 are communicated, and the external water is softened by the electronic water softener 120 and then enters the dishwasher body 110. When the first port and the third port of the multi-way valve 170 are communicated, the first pipe 130 is communicated with the third pipe 150, and at this time, the external water directly enters the dishwasher body 110 without being softened by the electronic water softener 120. The first line 130 is selectively communicable with the second line 140 or the third line 150 via a multi-way valve 170.
In some embodiments, the hardness detector 160, the multi-way valve 170, and the electronic water softener 120 are all electrically connected to the controller 180. After the hardness detection device 160 detects the water hardness value of the washing water at the water inlet of the electronic water softener 120, the controller 180 can obtain the water hardness value and control the first valve port of the multi-way valve 170 to be communicated with the second valve port or the third valve port according to the water hardness value, so as to control the first pipeline 130 to be communicated with the second pipeline 140 or the third pipeline 150 according to actual requirements. When the first valve port of the multi-way valve 170 is communicated with the second valve port, the controller 180 can also adjust the voltage of the electrode of the electronic water softener 120 according to the water hardness value, thereby adjusting the soft water capacity, ensuring the soft water effect, being applicable to areas with different water hardness values, and improving the adaptability of the dishwasher 100.
In some embodiments, the multi-way valve 170 is a three-way valve. Of course, in other embodiments, the multi-way valve 170 may be designed as a four-way valve, a five-way valve, etc. according to actual requirements.
In some embodiments, the dishwasher 100 further includes a fourth circuit, and the first circuit 130 is selectively communicated with the second circuit 140, the third circuit 150, or the fourth circuit. The fourth pipeline is provided with a heating device, the heating device can heat the washing water flowing through the fourth pipeline, and one end of the fourth pipeline departing from the first pipeline 130 is communicated with the outlet end of the electronic water softener 120. The external water source can enter the dishwasher body 110 through the first and second pipes 130 and 140, or through the first and third pipes 130 and 150, or through the first and fourth pipes 130 and 130 to wash dishes in the dishwasher 100. When the tableware in the dish washer 100 is washed by using warm water or hot water, the first pipeline 130 and the fourth pipeline are communicated, an external water source enters the dish washer body 110 after being heated by the heating device on the fourth pipeline so as to wash the tableware in the dish washer 100, the use requirements of different users are met, and the applicability and the practicability of the dish washer 100 are improved. It is understood that the heating device may be designed as any suitable heating structure, such as an electric heating structure, etc., without limitation.
Specifically, the multi-way valve 170 also has a fourth port. The fourth valve port is communicated with a fourth pipeline. The first port of the multi-way valve can be selectively communicated with the second port, the third port and the fourth port of the multi-way valve, so that the first pipeline 130 can be selectively communicated with one of the second pipeline 140, the third pipeline 150 or the fourth pipeline.
In some embodiments, the third conduit 150 may be omitted.
Referring to fig. 2, fig. 2 is a flowchart illustrating a control method of a dishwasher according to an embodiment of the present application. The control method of the dishwasher is realized by the dishwasher. Specifically, as shown in fig. 2, the control method of the dishwasher includes the steps of:
and S101, acquiring a water quality hardness value of the inlet end of the electronic water softener.
Specifically, the hardness sensor may be capable of detecting a water hardness value of the washing water or the external water source flowing through the first pipe. The water quality hardness value is the water quality hardness value of the inlet end of the electronic water softener. The water hardness value detected by the hardness sensor can be fed back to the controller, and the controller can acquire the water hardness value detected by the hardness sensor so as to control the softening and/or regeneration of the electronic water softener according to the water hardness value.
And S102, determining preset water softening conditions met by the water quality hardness value of the inlet end of the electronic water softener, wherein different preset water softening conditions correspond to different water softening modes.
Specifically, after the water quality hardness value of the inlet end of the electronic water softener is obtained, the controller can determine the preset water softening condition met by the water quality hardness value of the inlet end of the electronic water softener according to the water quality hardness value. Different preset water softening conditions correspond to different water softening modes. Different preset water softening conditions and corresponding water softening modes can be set according to actual requirements, and can be set by a manufacturer of the dishwasher, or can be set by a user of the dishwasher, and the like, and are not limited herein.
Illustratively, the preset water softening conditions include a first water softening condition, a second water softening condition, and a third water softening condition. The first water softening conditions include: the water quality hardness value is greater than or equal to the first hardness threshold value and is less than the second hardness threshold value. The second water softening conditions include: the water quality hardness value is greater than or equal to the second hardness threshold and is less than a third hardness threshold. The third water softening condition comprises: the water quality hardness value is greater than or equal to the third hardness threshold value.
The first hardness threshold, the second hardness threshold and the third hardness threshold can be set according to actual requirements, for example, the first hardness threshold is 0-80PPM, that is, 0PPM, 50PPM, 80PPM and any other suitable value in 0-80 PPM. The second hardness threshold is 81PPM-300PPM, i.e., 81PPM, 200PPM, 300PPM, or any other suitable value from 81PPM-300 PPM. The third hardness threshold is 301PPM-600PPM, i.e. 301PPM, 500PPM, 600PPM and any other suitable value from 301PPM-600 PPM.
In some embodiments, the first, second and third water softening conditions correspond to a first, second and third water softening regime, respectively. The first water softening mode is as follows: the voltage of the electronic water softener is a first voltage. The second water softening mode is as follows: the voltage of the electronic water softener is a second voltage. The third water softening mode is as follows: the voltage of the electronic water softener is a third voltage. Wherein the third voltage is greater than the second voltage, which is greater than the first voltage. Therefore, the controller can control the voltage of the electrode of the electronic water softener according to the water quality hardness value, so that the dishwasher can ensure the soft water effect at the place with lower water quality hardness value, and the adaptability of the dishwasher is improved.
The first voltage, the second voltage and the third voltage can be designed to be any suitable values according to actual requirements. Illustratively, the first voltage is 0V-12V, i.e., any one of 0V, 12V, and 0 to 12V. The second voltage is 12V-24V, i.e., any one of 0V, 12V, and 0 to 12V. High voltage range: 24V-36V, i.e. any of 0V, 12V and 0 to 12V.
And S103, softening the washing water flowing through the electronic water softener according to a water softening mode corresponding to the determined preset water softening condition.
Specifically, after the preset water softening condition is determined, the washing water flowing through the electronic water softener is softened according to the water softening mode corresponding to the determined preset water softening condition.
In some embodiments, if the water hardness value is less than a first hardness threshold value, the first pipeline is controlled to be communicated with the third pipeline. At this time, the water hardness value does not satisfy each preset water softening condition. Specifically, when the water hardness value is smaller than the first hardness threshold value, the water quality of the washing water in the first pipeline is soft, and the washing water can directly enter the dishwasher body from the third pipeline without being softened by the electronic water softener. When the water hardness value is greater than or equal to the first hardness threshold value, the water quality of the washing water in the first pipeline is hard, and the electrons are required to be softened by the water softener and then enter the dishwasher body to clean the tableware, so that the generation of scale is reduced or avoided. At this time, the dishwasher can determine a corresponding preset softening condition according to the water quality hardness value, and control the electronic water softener to soften the washing water flowing through the electronic water softener according to a water softening mode corresponding to the preset water softening condition.
Specifically, when the water hardness value is greater than or equal to the first hardness threshold and less than the second hardness threshold, the controller adjusts the voltage of the electrodes of the electronic water softener to a first voltage, and at the moment, a first electric field can be generated between the two electrodes of the electronic water softener. When the washing water with calcium and magnesium ions flows through the electronic water softener, the calcium and magnesium ions move towards the electrodes under the action of the first electric field and are finally adsorbed by the electrodes, so that the washing water entering the dishwasher body is softened.
When the water hardness value is greater than or equal to the second hardness threshold value and less than the third hardness threshold value, the controller adjusts the voltage of the electrodes of the electronic water softener to a second voltage, and at the moment, a second electric field can be generated between the two electrodes of the electronic water softener, so that the washing water flowing through the electronic water softener is softened. When the water hardness value is greater than or equal to the third hardness threshold value, the controller adjusts the voltage of the electrodes of the electronic water softener to a third voltage, and at the moment, a third electric field can be generated between the two electrodes of the electronic water softener, so that the washing water flowing through the electronic water softener is softened. Wherein the third voltage is greater than the second voltage, which is greater than the first voltage. The higher the voltage of the water softener, the higher the intensity of the generated electric field, and the stronger the soft water capacity, whereas the lower the voltage of the water softener, the weaker the soft water capacity. Therefore, the dish washing machine provided by the embodiment of the application can adjust the soft water capacity of the electronic water softener according to the water quality hardness value, can ensure the soft water effect, can be suitable for areas with different water quality hardness values, and improves the adaptability of the dish washing machine 100.
In some embodiments, the water softening control method further comprises: determining preset regeneration conditions which are met by the water quality hardness value of the inlet end of the electronic water softener, wherein different preset regeneration conditions correspond to different water softener regeneration modes; and injecting flushing liquid into the electronic water softener according to the regeneration mode of the water softener corresponding to the determined preset regeneration condition so as to flush the electrodes of the electronic water softener.
Specifically, after the water quality hardness value of the inlet end of the electronic water softener is obtained, the controller can determine the preset regeneration condition met by the water quality hardness value of the inlet end of the electronic water softener according to the water quality hardness value. Different preset regeneration conditions correspond to different water softener regeneration modes. Different preset regeneration conditions and corresponding water softener regeneration modes can be set according to actual requirements, and can be set by a manufacturer of the dishwasher, or can be set by a user of the dishwasher, and the like, and are not limited herein.
Illustratively, the preset regeneration conditions include a first regeneration condition, a second regeneration condition, and a third regeneration condition. The first regeneration condition comprises: the water quality hardness value is greater than or equal to the first hardness threshold value and is less than the second hardness threshold value. The second regeneration conditions include: the water quality hardness value is greater than or equal to the second hardness threshold and is less than a third hardness threshold. The third regeneration conditions include: the water quality hardness value is greater than or equal to the third hardness threshold value.
It is understood that the first hardness threshold, the second hardness threshold and the third hardness threshold in the embodiments of the present application may be the same as or different from those in the above embodiments, and are not limited herein.
The first, second and third regeneration conditions correspond to the first, second and third water softener regeneration modes, respectively. The regeneration mode of the first water softener is as follows: the accumulated water inflow of the electronic water softener is smaller than or equal to the first water quantity threshold value and larger than or equal to the second water quantity threshold value. The second water softener regeneration mode is as follows: the accumulated water inflow of the electronic water softener is smaller than the second water quantity threshold and is larger than or equal to the third water quantity threshold. The third water softener regeneration mode is as follows: the accumulated water inflow of the electronic water softener is smaller than the third water volume threshold and is larger than or equal to the fourth water volume threshold. The first, second, third and fourth water volume thresholds may be set according to actual demand, for example, the first water volume threshold is 135L, the second water volume threshold is 45L, the third water volume threshold is 15L, the fourth water volume threshold is 5L, and so on.
In some embodiments, if the water hardness value is greater than or equal to a first hardness threshold, the first pipeline is controlled to be communicated with the second pipeline, and a preset softening condition that the water hardness value of the inlet end of the electronic water softener meets is determined. Specifically, if the water hardness value is greater than or equal to the first hardness threshold, it indicates that the water quality of the washing water in the first pipeline is relatively hard, and the washing water needs to be softened by the electronic water softener and then enters the dishwasher body to clean the dishware, so as to reduce or avoid the generation of scale. At the moment, the dishwasher controls the first pipeline to be communicated with the second pipeline, and can determine the corresponding preset softening condition according to the water hardness value, so that the water softening capacity of the electronic water softener can be adjusted according to actual needs.
In some embodiments, the dishwasher can determine the preset softening condition and the preset water softener regeneration mode which are met by the water quality hardness value of the inlet end of the electronic water softener, compared with the dishwasher adopting the resin water softener, the dishwasher does not need to use soft water salt to wash the electronic water softener, avoids the waste of the soft water salt, does not need to add the soft water salt manually, and reduces the labor cost; and the problem that no soft water effect is caused by the delay of the regeneration of the resin water softener at a place with higher water hardness can be avoided. In addition, the dish-washing machine provided by the embodiment of the application can automatically control the soft water effect of the electronic water softener according to actual needs, and can greatly prolong the service life of the electronic water softener; meanwhile, the electronic water softener can also adsorb metal ions such as iron and aluminum, so that the washing water entering the dish washing machine after being softened by the electronic water softener is cleaner.
Illustratively, if the water hardness value is greater than or equal to 50PPM, which indicates that the water quality of the washing water in the first pipeline is relatively hard, the washing water needs to be softened by an electronic water softener and then enters the dishwasher body to wash the dishes. Therefore, if the water hardness value is more than or equal to 50PPM, the first pipeline is controlled to be communicated with the second pipeline, and the washing water in the first pipeline is softened by the electronic water softener before entering the interior of the dishwasher. If the water hardness value is less than 50PPM, the water quality of the washing water in the first pipeline is soft, the first pipeline is controlled to be communicated with the third pipeline, and the washing water in the first pipeline can directly enter the dishwasher body from the third pipeline without being softened by the electronic water softener.
Illustratively, when the water hardness value of the inlet end of the electronic water softener is less than 50PPM, the controller controls the first valve port of the multi-way valve to be communicated with the third valve port of the multi-way valve, so that the first pipeline is communicated with the third pipeline. And the external water source enters the dishwasher body through the first pipeline and the third pipeline to clean the tableware. At this time, the electronic water softener is not subjected to brine flushing regeneration.
When the water hardness value of the inlet end of the electronic water softener is more than or equal to 50PPM and less than 200PPM, the controller controls the first valve port of the multi-way valve to be communicated with the second valve port of the multi-way valve and adjusts the voltage of the electronic water softener to be a first voltage, so that an external water source enters the dishwasher body to wash tableware after being softened by the electronic water softener through the first pipeline and the second pipeline. When the accumulated water inflow reaches A liters, the controller adjusts the voltage of the electronic water softener to be zero. The external water source enters the electronic water softener of the second pipeline through the first pipeline, and because the voltage of the electronic water softener is zero, the electric field disappears, the adsorption capacity of the electronic water softener on calcium, magnesium and the like disappears, and at the moment, the external water source flowing through the electronic water softener can discharge the calcium, magnesium and the like adsorbed on the electrodes of the electronic water softener out of the dish-washing machine through different pipelines, so that the electrodes of the electronic water softener are washed. The sewage flowing out of the outlet end of the electronic water softener, namely the external water source after washing the electrode of the electronic water softener, can be discharged out of the dishwasher through a sewage discharge pipeline and the like. And when the accumulated water inflow is less than A liters, the voltage of the electrode of the electronic water softener is not adjusted to be zero, and the electrode of the electronic water softener is not washed.
When the water hardness value of the inlet end of the electronic water softener is more than or equal to 200PPM and less than 500PPM, the controller controls the first valve port of the multi-way valve to be communicated with the second valve port of the multi-way valve, so that the first pipeline is communicated with the second pipeline. The outside water source enters the dishwasher body to clean the tableware after being softened by the electronic water softener through the first pipeline and the second pipeline. When the accumulated water inflow reaches B liters, the controller adjusts the voltage of the electronic water softener to be zero. And an external water source enters the electronic water softener of the second pipeline through the first pipeline, so that the electrodes of the electronic water softener are washed. Wherein B is less than A. And when the accumulated water inflow is less than B liters, the voltage of the electrode of the electronic water softener is not adjusted to be zero, and the electrode of the electronic water softener is not washed.
When the water hardness value of the inlet end of the electronic water softener is larger than or equal to 500PPM, the controller controls the first valve port of the multi-way valve to be communicated with the second valve port of the multi-way valve, so that the first pipeline is communicated with the second pipeline. The outside water source enters the dishwasher body to clean the tableware after being softened by the electronic water softener through the first pipeline and the second pipeline. When the accumulated water inflow reaches C liters, the controller adjusts the voltage of the electronic water softener to be zero. And an external water source enters the electronic water softener of the second pipeline through the first pipeline, so that the electrodes of the electronic water softener are washed. Wherein C is less than B. And when the accumulated water inflow is less than C liters, the voltage of the electrode of the electronic water softener is not adjusted to be zero, and the electrode of the electronic water softener is not washed.
In some embodiments, the control method further comprises: and if a heating instruction is received, controlling the first pipeline to be communicated with the fourth pipeline. In particular, the heating instruction may be input to the dishwasher by the user in any suitable manner, such as the user operating a heating control button or the like. After the controller receives the heating instruction, the first pipeline and the fourth pipeline are controlled to be communicated, so that the washing water is heated, the use requirements of different users are met, and the applicability and the practicability of the dish washing machine are improved.
