In other embodiments, the electrodialysis module is connected with a first flow control valve and a second flow control valve, the first flow control valve is respectively connected with a first water treatment chamber of the electrodialysis module and a water inlet pipe of the water making device, and the second flow control valve is respectively connected with a second water treatment chamber of the electrodialysis module and a water inlet pipe of the water making device, and the electrodialysis module is provided with a positive electrode pair and a negative electrode pair for electrodialysis purified water. Specifically, as shown in fig. 7, determining that the water producing device enters a prefabricated water program, and controlling the electrodialysis module to work includes:
s701, controlling the electrification of the positive and negative electrode pairs.
Optionally, the control module controls the positive and negative electrode pairs to be energized.
S702, acquiring polarity information of a positive electrode pair and a negative electrode pair.
Optionally, the acquisition module detects polarity information of the positive and negative electrode pairs. For example, the positive and negative electrode pairs include a third electrode and a fourth electrode, and the acquisition module detects the polarities of the first electrode and the second electrode.
S703, determining the flow ratio of the first flow control valve and the second flow control valve according to the polarity information.
Optionally, the flow rate of the first control flow valve and the flow rate of the second control flow valve have a certain ratio value, for example, the flow rate ratio of the first control flow valve to the second control flow valve is 3 or 1/3.
It is to be understood herein that the ratio of the flow rates of the first flow control valve and the second flow control valve corresponds to the polarity of the positive and negative electrode pairs for effecting the water purification process of the electrodialysis module. For example, the flow ratio of the first control flow valve to the second control flow valve is 3, corresponding to the first electrode being the positive electrode and the second electrode being the negative electrode, when the flow ratio of the first control flow valve to the second control flow valve becomes 1/3, corresponding to the first electrode becoming the negative electrode and the second electrode becoming the positive electrode, so that calcium and magnesium scale in the membrane stack of the electrodialysis module can not be always deposited on one electrode by frequently changing the waterway and the electrode, thereby realizing the prolongation of the service life of the membrane stack. Thus, after determining that the electrodialysis module needs to be rinsed, the adjustment of the first flow control valve, the second flow control valve, and the positive-negative electrode pair may be performed before the electrodialysis module is rinsed, or after the electrodialysis module is rinsed.
Therefore, when a user approaches the water production equipment, the water production equipment can switch on the power supply of the electrodialysis module (EDR) in advance, and the current is supplied in advance to maintain the purity of the purified water in the membrane stack of the electrodialysis module, so that the waiting time is reduced.

Specifically, the water making equipment comprises a built-in microwave module, and compared with a traditional water purifier, the electrodialysis water making equipment can generate water with different TDSs through controlling the electrodialysis module, so that the requirements of different personnel and different water scenes are met, the built-in microwave human body sensing module of the water making equipment can penetrate through any substances except metal accidents to detect moving objects, the purpose of detecting human bodies can be achieved by utilizing the Doppler effect, and the water making equipment is used for electrodialysis water making equipment and can detect surrounding moving objects under the condition that a panel is not perforated. Specifically, after the TDS detects the water quality of the water fed by a user, the time of different preparation target water quality is matched, the time is converted into the range of a microwave human body induction module, after a certain induction distance is preset by the microwave human body induction sensor, the human body approaches to the water production equipment, the control end reads the TDS condition of the water quality of the water production, if the water quality is lower than the requirement, the power supply detection of the electrodialysis membrane stack is automatically started, the voltage and current condition in the EDR is detected, the water production is automatically regulated, the purity of the water of the first cup of the water production equipment is maintained, the problem that the water purification tank is removed under the condition of adjustable water quality of the EDR is solved, the unstable condition of the first cup of water is caused, the water production time of waiting for the first cup of the water production equipment by electrodialysis by the user is reduced, the user experience is improved, and the intelligent degree of the water purifier is also improved.
The upper table is the relation between the water inflow TDS and the sensing distance, and the sensing distance is the detection range.
