Description

Regeneration method of water softener of dish washing machine and dish washing machine applying same

Technical Field

The invention relates to a water softening method, in particular to a regeneration method of a water softener of a dish washing machine and the dish washing machine applying the method.

Background

In the prior art, the controller of the dish washer can not know the water softening setting gear, and the water softener regeneration is carried out every time when the washing program is set, so that the washing flow is regenerated and washed with salt every time, and then the waste of water and salt is caused.

Disclosure of Invention

The invention mainly aims to solve the technical problems in the prior art and provide a water softener regeneration method of a dish washing machine, which saves water and salt.

Another object of the present invention is to provide a dishwasher applying the above method.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a method for regenerating a water softener of a dishwasher, comprising the steps of:

step one, judging whether the water inflow reaches the set gear softened water amount or not;

step two, if the set gear softened water amount is reached, performing soft water regeneration in a main washing stage or a drying stage, resetting the water inflow, and setting a salt flushing judgment value, otherwise not performing soft water regeneration;

step three, finishing the main washing stage or the drying stage;

and step four, judging whether a salt flushing judgment value is available, if so, carrying out salt flushing, and otherwise, not carrying out salt flushing.

Further, in the step one, the water inflow corresponding to each gear is set.

Further, an electronic gear is adopted, and at least 8 gears are arranged.

And further, a step is added between the second step and the third step, wherein the step is to judge whether the main washing stage is interrupted, and if the main washing stage is interrupted, salt flushing is carried out at the starting stage of the next program.

And further, a step is added between the second step and the third step, and the step is to judge whether the drying stage is interrupted or whether the time of the drying stage is less than that of the water-softening regeneration, and if the drying stage is interrupted or the time of the drying stage is less than that of the water-softening regeneration, salt flushing is carried out at the starting stage of the next program.

Further, in the fourth step, the salt-adding determination value is eliminated after the salt adding is finished.

The other technical scheme of the invention is as follows:

a dishwasher applying a dishwasher water softener regeneration method as described above.

In summary, the regeneration frequency and the salt flushing frequency of the water softener of the dishwasher are controlled by setting the corresponding water inflow of the gear and combining the judgment of the controller, so that the waste of water and salt is reduced. If the main washing stage or the drying stage is cancelled, the salt is flushed at the beginning of the next procedure, so that the regenerated water with very high hardness in the water-soft resin can be ensured not to enter the washing stage.

Detailed Description

The invention is described in further detail below with reference to the following detailed description and accompanying drawings:

in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example one

As shown in fig. 1, a method for regenerating a water softener of a dishwasher includes the steps of:

step one, a user sets gears on the premise of knowing water hardness, and the controller presets the water inflow corresponding to each water hardness gear. In order to avoid fewer gears, inaccurate control and waste of water and salt, in the embodiment, an electronic gear is adopted and at least 8 gears are set.

When the program of the dish washer starts and water enters, the controller judges whether the water inflow reaches the set gear softened water amount, namely whether the water inflow corresponding to the gear set by the user is reached.

And step two, if the set gear softened water quantity is reached, performing water softening regeneration in the main washing stage, resetting the water inflow in the program in the controller to be 0, setting a salt flushing judgment value, and setting a salt flushing memory in the controller to be 1. If not, the water soft regeneration is not carried out.

And step three, the controller judges whether the main washing stage is interrupted, and if the main washing stage is interrupted, salt flushing is carried out at the starting stage of the next program, so that the regenerated water with very high hardness in the water-soft resin can be ensured not to enter the washing stage. If the main wash stage is not interrupted, the following steps are performed.

And step four, finishing the main washing stage.

And step five, draining water after the main washing stage is finished, judging whether a salt flushing judgment value exists by the controller, namely the salt flushing judgment value set in the step two, flushing salt with the dishwasher drainage water if the salt flushing judgment value exists, and eliminating the salt flushing judgment value after the salt flushing is finished, namely the salt flushing storage in the controller is set to be 0. If the salt flushing judgment value is not available, salt flushing is not carried out, and only water is drained.

A dishwasher, the dishwasher water softener regeneration method of the above-mentioned step one to step five of application.

According to the regeneration method of the water softener of the dish washing machine and the dish washing machine applying the method, the regeneration frequency and the salt flushing frequency of the water softener are controlled by setting the corresponding water inflow of the gear and combining the judgment of the controller, so that the waste of water and salt is reduced. If the main washing stage is cancelled, the salt is flushed in the next procedure starting stage, so that the regenerated water with very high hardness in the water soft resin can be ensured not to enter the washing stage.

Example two

As shown in fig. 2, a method for regenerating a water softener of a dishwasher includes the steps of:

And step two, if the set gear softened water quantity is reached, performing water softening regeneration in a drying stage, resetting the water inflow in the program in the controller to be 0, setting a salt flushing judgment value, and setting a salt flushing memory in the controller to be 1. If not, the water soft regeneration is not carried out.

Step three, judging whether the drying stage is interrupted or not, and if the drying stage is interrupted or the time consumption is smaller than the time consumption, carrying out salt flushing at the starting stage of the next program

The controller judges whether the drying stage is interrupted or whether the time of the drying stage is less than that of the water softening regeneration, if the drying stage is interrupted or the time of the drying stage is less than that of the water softening regeneration, salt flushing is carried out at the starting stage of the next program, and therefore the regenerated water with high hardness in the water softening resin can be prevented from entering the washing stage. Without interruption of the drying stages, the following steps are carried out.

And step four, finishing the drying stage.

And step five, the controller judges whether a salt flushing judgment value exists, namely the salt flushing judgment value set in the step two, if so, salt flushing is carried out, and the salt flushing judgment value is eliminated after salt flushing is finished, namely the salt flushing storage in the controller is set to be 0. And if the salt dissolving judgment value is not available, salt dissolving is not carried out.

According to the regeneration method of the water softener of the dish washing machine and the dish washing machine applying the method, the regeneration frequency and the salt flushing frequency of the water softener are controlled by setting the corresponding water inflow of the gear and combining the judgment of the controller, so that the waste of water and salt is reduced. If the drying stage is cancelled, the salt is flushed in the next procedure starting stage, so that the regenerated water with very high hardness in the water-soft resin can be ensured not to enter the washing stage.

Similar solutions can be derived from the solution given in the figures, as described above. However, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present invention are within the scope of the technical solution of the present invention.
