In the present embodiment, the dishwasher is integrated with the sterilizing water generating device, and the dishwasher may first complete the preparation of the sterilizing water, and then directly introduce the prepared sterilizing water into the inner container to sterilize the inner container.
Specifically, the components of the disinfectant solution are not limited, and the disinfectant solution is preferably obtained by oxidizing sodium chloride. Sodium chloride is oxidized to form sodium hypochlorite, a sodium hypochlorite solution has strong oxidizing property, and the specific reaction process is as follows:
cathode 2Cl - -2e - ＝Cl 2
Anode 2H 2 O+2e - ＝H 2 +2OH -
And (3) total reaction: 2Cl - +2H 2 O＝H 2 +Cl 2 +2OH -
A disproportionation reaction will occur between chlorine and water: cl 2 +H 2 The generated HClO has certain oxidability, thereby realizing the killing effect on bacteria and viruses.
In the embodiment, the adopted salt is NaCl which is non-toxic and stable in property, is not easy to deteriorate, and is convenient to store and carry out electrolytic disinfection operation. For other chlorates, e.g. KCl, CaCl 2 And the like, which are not recommended to be adopted because of certain harm to human bodies.
After the sterilizing water enters the washing water containing space, the sterilizing water can kill viruses and bacteria through the high oxidizability of the sterilizing water.
S2, acquiring the water level of the disinfectant liquid;
the manner of obtaining the water level of the sterilizing water is not limited, and as a preferred embodiment, a water level sensor may be provided inside the washing water receiving space, and the liquid level height inside the washing water receiving space may be known by the water level sensor.
As a variant, the liquid level may also be determined by monitoring the volume of water entering the washing water receiving space, at which time a function between the liquid level and the volume may be put into the controller in advance, the volume of water entering the washing water receiving space is calculated by the flow meter, which further transmits the signal to the controller, and when the detected volume of water corresponds to the preset volume, the flow meter sends the signal to the controller, which further controls the stopping of water intake.
And S3, when the water level of the disinfectant fluid is higher than a preset water level, the controllable power supply is turned on to conduct the auxiliary anode, and the preset water level is higher than the lowest position of the auxiliary anode.
Specifically, the controllable power supply is weak current, which may be mains power connected to the dishwasher, and then the mains power is converted into weak current by a converter. Or a storage battery is adopted, and the power supply operation is realized through the storage battery.
Meanwhile, the auxiliary anode can be horizontally placed or vertically or obliquely placed, and when the auxiliary anode is vertically or obliquely placed, the normal work can be realized as long as the water level of the disinfectant liquid is over the root of the auxiliary anode.
In this embodiment, since the disinfectant liquid has high oxidizing property, it may cause oxidation of the inner wall of the inner container, resulting in conversion of elemental iron into iron ions, and the specific reaction is as follows:
Fe-3e - ＝Fe 3+
in this embodiment, an electrolytic cell is formed between the auxiliary anode, the disinfectant, the inner container and the controllable power supply, and the reaction between the cathode and the anode of the electrolytic cell is as follows:

In this embodiment, because the controllable power supply continuously provides electrons to the inner container, even if the elemental iron in the inner container is oxidized to form iron ions, at this time, due to the continuous transmission of electrons, the iron ions obtained just by oxidation can be rapidly captured, and thus are reduced again to obtain elemental iron, and further, the inner wall of the inner container can be effectively prevented from being oxidized.
Specifically, the washing water receiving space itself may be provided as a cup, as shown in fig. 1, the cup is disposed at a position below the inner container, and after water is introduced into the inner container, the water is gathered inside the cup, thereby achieving a water collecting operation.
For the auxiliary anode, it is made of inert material, such as carbon rod, inert metal such as copper, etc.
Further, after a period of sterilization, the present embodiment further includes the following steps:
s4, judging whether disinfection is finished or not;
in this embodiment, the manner of determining whether disinfection is completed is not limited, and as an implementation manner, it may be determined whether disinfection is completed through a reaction time period, for example, if the disinfection time is set to 5 minutes, and after the time reaches five minutes, it is determined that disinfection is sufficiently performed.
As another embodiment, whether the disinfection is finished or not can be judged by detecting the number of viruses or bacteria in the inner container. For example, when the amount of the virus or bacteria is lower than a certain set value, the residual bacteria or virus will not cause harm to human body, and disinfection can be determined to be completed.
S5, if the disinfection is finished, introducing clean water into the liner;
after the disinfection is completed, the inner container needs to be cleaned as necessary to avoid the residual of the disinfection water, i.e., the inner container needs to be rinsed.
In this embodiment, the inner bag self is connected with the inlet tube, and the inlet tube can directly be connected with tap, also can be connected with water storage facilities such as water tanks. Meanwhile, a valve is arranged on the water inlet pipe, the valve can be a manual valve or an electric valve, and when the electric valve is adopted, the electric valve is connected with the controller, so that the controller can conveniently control the cleaning water to be introduced into the inner container at the first time.
S6, judging whether the clean water is normally introduced;
in the embodiment, the flow meter is used for judging the introduction of the cleaning water, if water passes through the flow meter, the impeller and the magnet in the flow meter are driven by water pressure to rotate to generate a circularly alternating magnetic field, and the reed pipe counts along with the circularly alternating magnetic field and generates a water signal.
And S7, if the clean water is normally introduced, controlling the sterilized water in the inner container to be discharged, and turning off the controllable power supply.
Specifically, after the clean water can be normally introduced, the sterilized water in the inner container is discharged, then the clean water is introduced into the inner container in batches, and the inner container is repeatedly washed.
Further, after the clean water can normally be introduced into the inner container, the method further comprises the following steps: and after the disinfectant water is discharged, introducing cleaning water into the inner container, and stopping discharging the cleaning water in the inner container to enable the cleaning water to wash the inner container.
At the moment, the dishwasher enters a rinsing stage, and the concentration of the disinfectant can be reduced through rinsing, so that the disinfectant is prevented from corroding the inner container.
Further, after the inner container is fully rinsed by the cleaning water, in order to avoid the inner container from being rusted by the residual cleaning water, the method also comprises the following steps: and after the inner container is washed, controlling the clean water in the inner container to be discharged, and controlling the ventilation device to be started.
The ventilating device itself is arranged inside the dishwasher and when the ventilating device is activated, the resulting air flow will quickly blow the cleaning water to the outside of the dishwasher.
And S8, if the clean water is not normally introduced, stopping discharging the sterilized water in the inner container, and turning on the controllable power supply.
In this embodiment, there may be a case where the clean water cannot be introduced into the dishwasher, for example, a power failure occurs in the tap water pipe, or a blockage occurs in the water inlet pipe. If the clean water can not normally let in the inner bag, then if the sterile water in the inner bag still discharges to the external world, still can have partial sterile water to remain in the inner bag this moment, because the liquid level is lower in the inner bag, even controllable power is opened this moment, also can't fully form the electrolytic bath between auxiliary anode and the inner bag, the condition of so corroding will continuously take place, causes the corruption to the inner bag.
In the embodiment, in order to avoid the above situation, firstly, whether the cleaning water can be normally introduced into the inner container is judged, if the cleaning water cannot be normally introduced due to reasons, the drainage operation of the inner container is stopped at the moment, and as the liquid level of the sterilizing water is higher, a stable electrolytic cell can be formed among the auxiliary anode, the inner container and the controllable power supply, and at the moment, only the controllable power supply needs to be controlled to be normally electrified, so that the corrosion situation caused when the sterilizing water is not fully discharged can be avoided.
