Of course, cleaning the fruits and vegetables is only one function of the water purifier, and other functions of the water purifier are not described herein again. The method for cleaning fruits and vegetables is described in detail below.
Referring to fig. 2, the key instruction and the water inflow flow are detected in real time, if the first key instruction is received and the current water inflow flow value is greater than the first flow set value, it is determined that the user cleans the fruits and vegetables, and at this time, the electrolysis module 23 is controlled to be started. If the user does not wash the fruits and vegetables, the electrolysis module 23 is in a closed state to save electric energy, and the service life of the electrolysis module 23 can be prolonged.

If the first key instruction is not received and the current flow value is larger than the first flow set value, it is determined that the user is using the domestic water, but the 'fruit and vegetable washing' function is not triggered.
Referring to fig. 3, when the fruits and vegetables are washed, the TDS value of the inlet water is acquired, and if the current TDS value is smaller than the set TDS value, TDS regulating solution is added into the inlet water to maintain the current of the electrolysis module constant.
And controlling the opening and closing of the flow valve 26 of the TDS adjusting module according to the comparison between the current TDS value and the set TDS value. Adding TDS conditioning fluid to the incoming water, i.e., opening flow valve 26, enables the TDS conditioning fluid to flow into the incoming water. The addition of TDS conditioning fluid to the influent water is stopped, i.e., flow valve 26 is closed so that TDS conditioning fluid cannot flow into the influent water.
Wherein, the TDS regulating solution can be the existing sodium chloride solution.
In the process of adding the TDS regulating solution into the inlet water, the inlet water flow is continuously acquired, and if the current inlet water flow value is not greater than the first flow set value, the TDS regulating solution is stopped from being added and the electrolysis module 23 is closed.
In the process of adding the TDS regulating solution to the inlet water, constantly acquire a key instruction, and if a second key instruction is received, stop adding the TDS regulating solution and close the electrolysis module 23.
If the first key instruction is received, the electrolysis module 23 is started, and if the second key instruction is received, the electrolysis module 23 is closed. The key functions as a switch.
If current inflow flow value is greater than first flow setting value and has not received the second key instruction, then add the TDS value of intaking constantly at the in-process of adding the TDS regulating solution into intaking, if current TDS value is not less than and sets for the TDS value, then stop adding the TDS regulating solution. And if the current TDS value is smaller than the set TDS value, continuously adding the TDS regulating solution into the inlet water.
The output current of the electrolysis module 23 should be in a constant current state, for example, the output current is 1A or 2A or 3A. The TDS value is appropriate when the output current of the electrolysis module 23 is maintained constant, indicating that electrolysis is stable. If the output current of the electrolysis module 23 is small, indicating that the electrolysis is not stable, the TDS value needs to be adjusted.
In order to facilitate the addition of control TDS regulating solution, the aperture of the flow valve 26 in the TDS regulating module is adjustable, and the flow of the TDS regulating solution can be in different gears to satisfy the demand and avoid causing waste.
When beginning to add the TDS regulating fluid in intaking, the flow of TDS regulating fluid is in initial gear, at the in-process that adds the TDS regulating fluid in intaking, according to the flow gear of electrolysis module 23's current regulation TDS regulating fluid.
Referring to fig. 4, the current of the electrolysis module 23 is detected, and if the current value is smaller than the first set current value, the flow rate of the TDS regulating solution is increased to the first gear.
When the flow of the TDS regulating solution is in a first gear and lasts for a first set time, if the current value is smaller than a first set current value, the flow of the TDS regulating solution is increased to a second gear. This indicates that the flow rate of TDS control fluid in the first gear is not sufficient. Similarly, the gear can be continuously increased upwards according to the detection parameters, and details are not repeated here.
Alternatively, referring to fig. 5, the current of the electrolysis module 23 is detected, and if the current value is smaller than the first set current value, the difference between the first set current value and the current value is obtained, and the flow rate of the TDS adjusting solution is adjusted according to the difference.
The difference is divided into several ranges in the database, for example, the flow rate of the TDS conditioned fluid is adjusted to a first gear when the difference is within a first range, and the flow rate of the TDS conditioned fluid is adjusted to a second gear when the difference is within a second range. At this moment, the flow regulation to TDS regulating solution is not the regulation of first gear, but can stride the gear and adjust, can adjust to second gear or even third gear from initial gear, adjusts more fast.
In this embodiment, be provided with two scopes, when the difference is located the first scope, then adjust the flow of TDS regulating fluid to first gear, when the difference is located the second scope, then adjust the flow of TDS regulating fluid to second gear, when the difference is higher than the second scope, then adjust the flow of TDS regulating fluid to highest gear.
The required cleaning intensity is different for different types of fruits and vegetables. For example, broccoli requires a more intensive wash than tomatoes. Although the output current of the electrolysis module 23 is constant, the magnitude of the output current and thus the electrolysis intensity can be changed by changing the power of the electrolysis module 23.
In the present embodiment, the electrolytic strength is changed by the key function. When the surface of the fruit and vegetable being cleaned by the user is not smooth and is difficult to clean, the user can trigger the corresponding key command to change the electrolytic strength.
If the first key instruction is received, the electrolysis module 23 is at the initial power, if the third key instruction is received, the power of the electrolysis module 23 is increased, and if the fourth key instruction is received, the power of the electrolysis module 23 is decreased.
In this embodiment, three keys are provided, which may be identified as "fruit and vegetable wash", "+" and "-".
When the 'fruit and vegetable washing' is clicked, a first key instruction is triggered, the electrolysis module 23 is started and is located at the initial power, when the 'fruit and vegetable washing' is clicked again, a second key instruction is triggered, and the electrolysis module 23 is closed and stops adding the TDS regulating solution.
When the user presses the plus button once, a third button instruction is triggered, and the power of the electrolysis module 23 is increased; when the electrolysis module 23 is powered down, the fourth key command is triggered when the "-" is pressed at each point. Of course, the power of the electrolysis module 23 has an upper limit and a lower limit, and can be set according to actual needs.
Be provided with the liquid level detector in the TDS container 25, the liquid level of real-time detection TDS regulating solution if current liquid level value is less than and sets for the liquid level value, then triggers alarm device to the suggestion user in time adds the TDS regulating solution.
