Drawings
FIG. 1 is a control method of a water softener of a dishwasher and a control flowchart of the dishwasher according to an embodiment of the present invention.
Detailed Description
The application scheme is further described below with reference to the accompanying drawings:
example (b):
referring to fig. 1, the present embodiment provides a method for controlling a water softener of a dishwasher, the operating stage of which includes a reduction stage of the water softener, the reduction stage including a salt flushing process, a reducing resin process, a first brine discharge process and a second brine discharge process, the first brine discharge process and the second brine discharge process being performed after the salt flushing process and the reduction process, and the first brine discharge process and the second brine discharge process being performed after a previous wash and before a subsequent wash, respectively;
when the dishwasher enters the first brine discharge process, a water pump of the dishwasher inputs residual water in a water tank of the dishwasher into a resin cavity of a water softener and stops the dishwasher after high-concentration brine in the resin cavity is discharged out of the dishwasher;
this salt water process is arranged before the dish washer gets into the washing stage of next time to this second time, and when the dish washer got into the salt water process of arranging for the second time, the water pump was discharged the remaining high concentration salt water in the resin chamber behind the water tank partial water input resin chamber when washing next time.
It should be noted that a complete washing cycle of a typical dishwasher typically comprises four operating phases: a pre-wash stage, a main wash stage, a rinse stage, and a drying stage. Wherein, in the pre-washing stage, the washing water will roughly wash the dishes to be washed in the dishwasher to remove the larger residues on the dishes to be washed, and the washing water is not added with detergent; after the pre-washing stage is finished, the dish-washing machine enters a main washing stage, in the main washing stage, the washing water is added with the detergent and is heated to a relatively high temperature, and the higher temperature can give greater activity to the detergent, so that oil stains on the tableware to be washed can be relatively thoroughly removed; after the main washing stage is finished, the dishwasher enters a rinsing stage, wherein the washing water in the rinsing stage is clear water without detergent and is used for cleaning the detergent such as foam and the like remained on the tableware to be cleaned; after the rinsing stage is finished, the dish-washing machine enters a drying stage, and tableware is dried and sterilized through drying equipment, so that the whole washing process is finished. As can be seen from the above description, in the present embodiment, the rinsing stage refers to a stage in which the washing water is clean water without detergent added, and is used for cleaning the detergent, such as foam, remained on the dishes to be cleaned.
In some embodiments, the dishwasher may also have only a main wash phase and a rinse phase, or only a main wash phase, a rinse phase and a dry phase, etc. The operation stage of the dishwasher is preset in a corresponding program, and after a user starts the dishwasher, the dishwasher automatically operates according to the preset program.
Because the water yield in the dish washer water tank is greater than the water yield that dish washer main wash stage and rinsing stage used, but be less than the water yield that main wash stage and rinsing stage and reduction stage used again, after the water softener of dish washer got into reduction stage, remaining water is not enough to once only discharge the high concentration salt water that forms in the water softener after the reduction, if there is enough water then need bulky water tank, just make the volume that has increased dish washer or reduced the practical volume of dish washer intangible, in this embodiment, divide into twice the process of discharging high concentration salt water, can accomplish the discharge of high concentration salt water and reduce watered operation simultaneously, reduce the volume of water tank, thereby the occupation space of water tank has been reduced.
As mentioned above, the dishwasher is also drained at the later stage of the rinsing stage, after the rinsing water in the rinsing stage enters the inner tub, the reduction stage of the water softener is started, water in the water tank provides a small amount of water to the salt cavity of the water softener through the water pump of the dishwasher to form strong brine, because the water output from the water pump has a certain pressure, the strong brine moves to the resin cavity of the water softener, the strong brine stays for a set time or slowly flows to reduce the resin after entering the resin cavity, the high-concentration brine formed after reduction is respectively subjected to primary brine discharge and secondary brine discharge, high concentration salt solution in the later stage of the first salt solution discharging process is discharged out of the dishwasher together with the sewage in the rinsing stage so as to reduce the operation steps, reduce the work flow and save the power supply, the high concentration salt solution in the later stage of the second salt solution discharging process is directly discharged out of the dishwasher.
Further, the dish washing machine comprises a water softener, a drainage device, a heating device, a water tank, an inner container, a water pump, a washing pump and a control device, wherein the water pump is in price connection with the water tank and the water softener, the water outlet end of the water softener is communicated with the inner container, the drainage device is communicated with the inner container, the heating device heats water in the inner container, and the washing pump provides washing water for the inner container.
Further, the water softener is provided with salt chamber and solenoid valve, the salt chamber to resin chamber one-way intercommunication is in order to prevent the refluence, solenoid valve intercommunication water pump and salt chamber.
Further, when the dishwasher enters a salt flushing process, the electromagnetic valve is opened, and the water pump provides a small amount of water for the salt cavity to form strong brine and then enters the resin cavity to reduce the resin in the resin cavity.
Preferably, the salt in the salt cavity is sodium chloride.
Further, the strong brine flows slowly in the resin cavity to improve the reduction effect of the resin.
Further, the strong brine stays in the resin cavity for a set time to reduce the resin.
Further, the water consumption of the first brine discharge process and the second brine discharge process is consistent.
Preferably, the high-concentration brine in the first brine discharge process and the second brine discharge process contains a large amount of calcium ions and magnesium ions.
Further, the water consumption in the salt flushing process is far less than that in the salt discharging process.
Further, the dishwasher operating phase includes a rinsing phase, and the first brine discharge process occurs after the rinsing water is finished.
Further, a washing device and a heating device are arranged, and the washing device and the heating device do not work in the salt flushing process and the salt water discharging process.
A dishwasher including the method for discharging brine of the water softener.
The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
