[0063] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0064] In order to better understand the solutions, the professional terms involved in the embodiments of the present application are explained first.

[0065] The electrolysis module is used for electrolyzing water, generally refers to a component provided with a graphite electrode and a titanium electrode, and the graphite electrode is coated with a graphite layer. The graphite electrode and the titanium electrode can be relatively distributed on two sides of the inner wall of the electrolysis module to electrolyze water entering the electrolysis module after a voltage is applied.

[0066] In the following, the electrode detection method of the electrolysis module in the household appliance, the device and the household appliance provided by the embodiments of the present application will be described and explained in detail through several specific embodiments.

[0067] In an embodiment, an electrode detection method of an electrolysis module in a household appliance is provided, which is applied to a controller such as a single-chip microcomputer or a terminal device, and is used for detecting the electrode of the electrolysis module. Figure 1 As shown in the figure, the electrode detection method of the electrolysis module in the household appliance provided by the embodiment includes:

[0068] Step 101, obtaining a first current value of the working electrolysis module under a preset voltage;

[0069] Step 102, if the first current value is out of a preset range, determining that the electrode of the working electrolysis module is abnormal.

[0070] Among them, the working electrolysis module is located downstream of a water purification module in the household appliance, and the working electrolysis module is an electrolysis module to which a preset voltage is applied when the household appliance works.

[0071] By applying a preset voltage to the electrolysis module located downstream of the water purification module, the current of the electrolysis module is obtained, and the electrode of the electrolysis module is detected according to the current, so as to utilize the characteristics that the damage of the graphite layer of the electrode or the scaling of the electrode will affect the current, to realize the electrode state judgment of the electrolysis module based on the current, and thus improve the water safety.

[0072] In an embodiment, the electrolysis module can include a water inlet, a water outlet, and an upper electrode and a lower electrode arranged on the inner wall of the electrolysis module, as shown in the figure. Figure 2 The upper electrode is mainly a graphite electrode coated with a graphite layer, and the lower electrode is a titanium electrode. After the electrode in the electrolysis module is powered on, an electric field is formed inside the electrolysis module, and the high-chlorine water entering the electrolysis module is electrolyzed through the action of the electric field, so that the ions in the electrolysis module are affected by the electric field and move directionally to generate hypochlorite ions. At this time, the hypochlorite ions can kill bacteria in the fluid such as soft water flowing into the electrolysis module through the water inlet, and then the fluid after sterilization is discharged through the water outlet, so as to achieve the effect of water purification.

[0073] In an embodiment, the electrolysis module can also include a water inlet, a water outlet, and an upper electrode and a lower electrode arranged on the inner wall of the electrolysis module, as shown in the figure. Figure 3As shown, the electrolysis module comprises a first water inlet, a second water inlet, a water outlet, and an upper electrode and a lower electrode arranged on the inner wall of the electrolysis module. The upper electrode is mainly a graphite electrode coated with a graphite layer, and the lower electrode is a titanium electrode. After the electrodes in the electrolysis module are powered, an electric field is formed in the electrolysis module, and the high-chlorine water flowing into the electrolysis module through the first water inlet is electrolyzed by the electric field, so that the ions in the electrolysis module are affected by the electric field and move directionally to generate hypochlorous acid ions. At this time, the hypochlorous acid ions can kill bacteria in the fluid flowing into the electrolysis module through the second water inlet, such as soft water, and then the fluid after sterilization is discharged through the water outlet, achieving the effect of water purification.

[0074] In an embodiment, the electrodes of the electrolysis module are connected with a power supply. For example, the controller is connected with the power supply to control the power supply to apply a preset voltage to the electrolysis module, and at this time, the electrolysis module to which the preset voltage is applied is the working electrolysis module. If there are multiple electrolysis modules, the electrodes of each electrolysis module can be connected with the power supply in a parallel manner, so that the controller can control the power supply to apply a preset voltage to any electrolysis module, and then determine any electrolysis module as the working electrolysis module.

[0075] The preset voltage can be pre-set according to actual conditions.

[0076] In an embodiment, a current detection unit for detecting current is arranged in the controller. The current detection unit can be a current sensor, which is connected with the electrolysis module, for example, connected with the electrodes of the electrolysis module, so that when the power supply applies a preset voltage to the electrolysis module, the current detection unit can directly obtain the current of the electrolysis module. If there are multiple electrolysis modules, multiple current sensors can be arranged, and the electrodes of each electrolysis module are connected with each current sensor one by one, so that one current sensor can correspondingly obtain the current of one electrolysis module.

[0077] Alternatively, the current detection unit can also be an electric field intensity sensor, which can be used to sense the intensity of the electric field formed in the electrolysis module by the power supply through the electrodes, so as to obtain the current of the electrolysis module through the intensity of the electric field. If there are multiple electrolysis modules, multiple electric field intensity sensors can also be arranged, so that one electric field intensity sensor can correspondingly obtain the current of one electrolysis module to which a preset voltage is applied.

[0078] As shown in Figure 4 When there are multiple electrolysis modules, each electrolysis module is connected in sequence through the water inlets and outlets, so that the fluid flows through each electrolysis module starting from the first electrolysis module. As shown in Figure 3 The first electrolysis module can be an electrolysis module comprising a first water inlet and a second water inlet as shown in Figure 2The electrolysis module is shown. When multiple electrolysis modules exist, a preset voltage can be applied to only some of them during the water purification process. The electrolysis modules to which the preset voltage is applied are the working electrolysis modules, while the electrolysis modules to which the preset voltage is not applied are the standby electrolysis modules.

[0079] In one embodiment, such as Figure 5 As shown, in the water purification process, a purification module exists upstream of the electrolysis module. This purification module can be an electrodialysis membrane stack, composed of multiple anion and cation exchange membranes. Under the action of an applied DC electric field, the selective permeability of the ion exchange membranes to ions in the solution causes anions and cations to migrate and pass through the anion and cation exchange membranes respectively, achieving the purpose of desalination or concentration of the water, thus purifying the water. During water production, the controller controls the power supply to apply voltage to the electrodialysis membrane stack and the electrolysis module. The electrodialysis membrane stack receives raw water, and after the power supply applies voltage, it purifies the raw water through electrodialysis technology, producing purified water with adjustable TDS (Total Dissolved Solids). The purified water from the electrodialysis membrane stack then flows through the water path to the working electrolysis module for electrolytic sterilization.

[0080] Considering that the purification effect on raw water is poor when the water purification module is not working or malfunctioning, the total dissolved solids value of the purified water flowing into the working electrolysis module increases, which affects the first current value detected by the working electrolysis module, thus affecting the subsequent electrode detection results. Therefore, in one embodiment, before acquiring the first current value of the working electrolysis module at a preset voltage, the controller pre-detects whether the water purification module located upstream of the working electrolysis module is malfunctioning. If it is determined that the water purification module is in normal working condition, the first current value of the working electrolysis module at the preset voltage is acquired; otherwise, the water purification module is determined to be malfunctioning, and water production is terminated.

[0081] The detection of whether the water purification module is malfunctioning can be achieved by installing detectors on both the inlet and outlet sides of the module. These detectors acquire the total dissolved solids (TDS) value of the raw water entering the module (inlet TDS) and the total dissolved solids (TDS) value of the purified water exiting the module (outlet TDS). Then, the water purification efficiency of the module is determined based on the inlet and outlet TDS values. The efficiency is then checked to see if it reaches the preset efficiency. If it does, the module is considered to be operating normally; otherwise, it is considered malfunctioning.

[0082] Alternatively, a detector can be installed only on the outlet side of the water purification module to detect the TDS of the outlet water. If the outlet water TDS reaches the preset TDS, the water purification module is determined to be in normal working condition; otherwise, it is determined to be abnormal.

[0083] Alternatively, the current value of the water purification module can be obtained after a preset voltage is applied to the water purification module, and whether the water purification module is abnormal can be determined according to the current value of the water purification module. If the current value of the water purification module is less than a preset current value, it is determined that the water purification module is in a normal working state, otherwise, it is determined that the water purification module is abnormal.

[0084] If the water purification module is in a normal working state, a first current value of the working electrolysis module under a preset voltage can be obtained, so as to avoid that the credibility of the first current value is low due to the abnormality of the water purification module, thereby improving the accuracy of the subsequent electrode detection result.

[0085] In an embodiment, when it is determined that the water purification module upstream of the working electrolysis module is in a normal working state, the first current value of the working electrolysis module under a preset voltage is obtained, comprising:

[0086] It is determined that the water purification module upstream of the working electrolysis module is in a normal working state, and the number of electrode switching of the working electrolysis module is detected.

[0087] When the number of electrode switching of the working electrolysis module reaches a preset number, the first current value of the working electrolysis module under a preset voltage is obtained.

[0088] In an embodiment, when it is determined that the water purification module is in a normal working state, the number of electrode switching of the working electrolysis module is detected. Once electrode switching means that the polarity of the positive and negative electrodes is exchanged once, that is, "reversing the electrodes". For example, the electrolysis module is provided with an upper electrode and a lower electrode, and the current upper electrode is positive and the lower electrode is negative. After reversing the electrodes, the upper electrode is negative and the lower electrode is positive. Considering that the graphite layer is usually shed due to frequent electrode switching, which affects the first current value. If the number of electrode switching is small, the first current value may not be affected by the shedding of the electrode graphite layer, but by the electrode fouling caused by not switching the electrodes, which can be solved by switching the electrodes next time. That is, when the number of electrode switching is small, electrode detection is not required. Therefore, by setting a preset number, the first current value is obtained after it is determined that the number of electrode switching of the working electrolysis module reaches the preset number, thereby improving the detection efficiency.

[0089] In an embodiment, after the controller obtains the first current value of the working electrolysis module, the current is compared with a preset range, and the electrode detection result of the electrolysis module is determined according to the comparison result, so that whether the electrodes of the electrolysis module are abnormal can be determined, and whether the sterilization rate of the electrolysis module is affected can be determined.

[0090] In an embodiment, the electrode detection result of the working electrolysis module is determined according to the first current value, comprising:

[0091] It is determined that the first current value is greater than a preset range, and it is determined that the electrodes of the electrolysis module are abnormal.

[0092] In an embodiment, under the action of long-term alternating current, the electrode coating can cause the graphite layer to fall off, affecting the ionization effect and causing the sterilization rate to decrease. At the same time, due to the falling off of the graphite layer, the current of the electrolysis module will increase under the premise of applying the same preset voltage to the electrolysis module. For example, as shown in the following table, the water preparation time and water flow rate are preset, and then a preset voltage is applied to the electrolysis module to obtain the sterilization effect and the corresponding electrode current. The sterilization effect and the corresponding electrode current are as follows:

[0093]

[0094] Through a large amount of experimental data, it can be determined that the current of the electrolysis module is always around 1.45 A under normal electrode conditions, and the current will increase significantly when the electrode is abnormal, such as 2.846 A in the above table. At the same time, the sterilization rate is measured to be 99.9% under normal electrode conditions, and the sterilization rate is measured to be 74% under abnormal electrode conditions, at which time the sterilization rate is significantly reduced.

[0095] Therefore, as shown in Figure 6 , it can be seen that under the premise of applying the same voltage, after obtaining the current of the electrolysis module, the current can be compared with the preset range to determine whether the current of the electrolysis module is too large. If it is greater than the preset range, it is determined that the current is too large, at which time it is determined that the electrode is abnormal, and the electrolysis module is closed. If it is less than the preset range, it is determined that the electrode detection result of the electrolysis module is normal, and the sterilization ability of the electrolysis module can meet the requirements.

[0096] Considering that when the electrode is abnormal, the current may also be too small at this time, at which time the electrolysis effect will also decrease, causing the sterilization effect to decrease. Therefore, in an embodiment, after obtaining the first current value of the working electrolysis module, if the first current value is less than the preset range, it is also determined that the electrode detection result of the working electrolysis module is abnormal.

[0097] The preset range can be determined according to actual conditions, such as a fixed value greater than the first current value under normal electrode conditions and less than the first current value measured under abnormal electrode conditions in the experimental results, such as 1.45 A or 1.5 A, or the preset range can be an interval of current values composed of each first current value under normal electrode conditions in the experimental results, such as [1.45 A, 1.5 A].

[0098] By detecting that the current is outside the preset range to determine that the electrode of the working electrolysis module is abnormal, the characteristics that the damage of the graphite layer of the electrode will cause the current to increase are used to realize the judgment of the electrode state of the working electrolysis module, and the water safety is improved.

[0099] Since the flow rate of the fluid in the working electrolysis module also affects the current, in order to avoid the interference of the flow rate on the detection result, in an embodiment, the preset range is determined according to the flow rate of the fluid flowing through the working electrolysis module.

[0100] For example, through a large amount of experimental data, the first current value generated by a normal working electrolysis module at a certain flow rate can be determined, and the first current value is taken as the preset range at the flow rate, thereby forming an information record table in which multiple flow rates correspond to multiple preset ranges. For example, when the flow rate is 2000 ml / min, the corresponding preset range is 1.45 A. When detecting the electrode of the electrolysis module, the flow rate of the fluid flowing through the working electrolysis module is obtained, and according to the flow rate, the preset range corresponding to the flow rate is obtained from the information record table, so as to detect whether the current of the working electrolysis module is abnormal through the preset range.

[0101] In addition to the flow rate of the fluid in the working electrolysis module, the total dissolved solids value in the fluid also affects the current. Therefore, in order to reduce the interference of water quality and flow rate on the detection result, in an embodiment, the preset range can be determined according to the inlet water TDS of the water purification module, the outlet water TDS of the water purification module, and the flow rate of the fluid flowing through the electrolysis module.

[0102] The relationship between the outlet water TDS, the flow rate V, the inlet water TDS, and the current I is as follows:

[0103]

[0104] In an embodiment, the working electrolysis module can further include a bacteria detection assembly arranged at the water inlet and the water outlet of the electrolysis module, for detecting the bacteria content of the fluid input into the electrolysis module and the fluid output from the electrolysis module. When the controller detects that the electrode detection result of the working electrolysis module is abnormal through the current, the bacteria content of the fluid input into the working electrolysis module and the bacteria content of the fluid output from the working electrolysis module are obtained, and the sterilization rate is obtained, so as to determine whether the electrode of the working electrolysis module is abnormal according to the sterilization rate, thereby improving the accuracy of the electrode detection result.

[0105] For example, if the electrode detection result of the working electrolysis module is detected to be abnormal through the current, it is detected whether the sterilization rate is greater than a preset sterilization rate. If it is less than or equal to the preset sterilization rate, it is determined that the electrode detection result is valid, and at this time, it is confirmed that the electrode of the working electrolysis module is abnormal. By combining the sterilization rate and the current of the working electrolysis module, whether the electrode of the working electrolysis module is abnormal is determined, thereby avoiding misjudgment and further improving the accuracy of the electrode detection result.

[0106] Since voltage fluctuation can also cause current anomaly, to avoid misjudgment caused by voltage fluctuation, in an embodiment, the controller can further include a voltage sensor for detecting voltage applied to the working electrolysis module. When the controller detects, through the current, that the electrode detection result of the working electrolysis module is abnormal, then according to the detection result of voltage obtained from the voltage sensor, it is determined whether the power supply is abnormal according to the obtained voltage detection result. If abnormal, it can be judged that the current anomaly is caused by the abnormality of the power supply, at which time it can be determined that the electrode of the working electrolysis module is not abnormal; otherwise, it can be judged that the current anomaly is caused by the electrode anomaly of the working electrolysis module, so as to determine the electrode anomaly of the working electrolysis module.

[0107] For example, to determine whether the power supply is abnormal, it can be determined by detecting whether the voltage obtained from the voltage sensor is greater than a preset voltage. If yes, it is determined that the power supply is abnormal; otherwise, it is determined that the power supply is normal. The preset voltage can be set according to actual conditions.

[0108] By detecting the voltage of the power supply to determine whether the current anomaly is caused by the abnormality of the power supply when the current anomaly of the electrolysis module is detected, the misjudgment of electrode anomaly caused by power supply anomaly is avoided, and the accuracy of the electrode detection result is further improved.

[0109] In an embodiment, when the current anomaly of the working electrolysis module is detected by a preset range or current threshold, the voltage of the power supply is first detected to determine whether the current anomaly is caused by the abnormality of the power supply; if not caused by the abnormality of the power supply, the sterilization rate is detected to determine whether it is greater than a preset sterilization rate, so as to finally determine whether the electrode of the working electrolysis module is abnormal according to the detection result of the sterilization rate, so as to more comprehensively detect the electrode anomaly of the working electrolysis module and realize more comprehensive electrode state judgment.

[0110] In an embodiment, it further includes:

[0111] The working electrolysis module with abnormal electrode is switched, and a second current value of the working electrolysis module under a preset voltage is obtained.

[0112] It is determined that the electrode anomaly is electrode damage when the second current value is outside the preset range.

[0113] In an embodiment, when it is determined that the electrode of the working electrolysis module is abnormal, it is considered that the electrode abnormality is caused by electrode fouling, so the electrode of the working electrolysis module with electrode abnormality can be switched first, if the electrode abnormality is caused by electrode fouling, the fouling formed on the surface of the electrode can be cleaned automatically after a period of time of switching the electrode, so that the current of the working electrolysis module tends to be normal, therefore, the electrode of the working electrolysis module with electrode abnormality can be switched first, and after a preset time, the second current value of the working electrolysis module is obtained, if the second current value obtained at this time is within the preset range, it is determined that the electrode abnormality is caused by electrode fouling, the graphite layer on the electrode is not detached, and the working electrolysis module can still be used normally. If the second current value is outside the preset range, it is determined that the electrode abnormality is caused by electrode damage due to the detachment of the graphite layer on the electrode, and the working electrolysis module cannot be used.

[0114] In an embodiment, the electrode detection method of the electrolysis module in the household appliance further comprises:

[0115] The working electrolysis module with electrode damage is turned off, and the power supply is controlled to apply a preset voltage to the standby electrolysis module downstream of the water purification module, and the standby electrolysis module working at the preset voltage is calibrated as the working electrolysis module;

[0116] The following steps are repeated:

[0117] A first current value of the working electrolysis module at the preset voltage is obtained;

[0118] If the first current value is outside the preset range, it is determined that the electrode of the electrolysis module is abnormal.

[0119] In an embodiment, when there are multiple electrolysis modules, in order to save power resources, only one of the multiple electrolysis modules can be applied with a preset voltage to serve as a working electrolysis module, and the rest of the electrolysis modules are in an off state to serve as standby electrolysis modules. When it is detected that the electrode detection result of the working electrolysis module is electrode damage, the working electrolysis module cannot be used, at this time, the working electrolysis module is turned off. At the same time, any standby electrolysis module is applied with a preset voltage to serve as a normal working electrolysis module to replace the working electrolysis module with abnormality to perform electrolysis work, so that when the electrode of a working electrolysis module is abnormal, the fluid flowing through each electrolysis module can still be effectively sterilized.

[0120] In an embodiment, the electrode detection method of the electrolysis module in the household appliance further comprises:

[0121] When it is determined that the electrode of the working electrolysis module is abnormal, a prompt information is generated.

[0122] In order to repair the working electrolysis module with abnormal electrode in time, in an embodiment, when it is determined that the electrode of the working electrolysis module is abnormal, a prompt information is generated, and the prompt information includes a prompt for the user to repair the working electrolysis module with abnormal electrode. Figure 7As shown, the controller can also be provided with a communication module, such as WIFI or ZigBee, for communication connection with an external terminal. When an electrode abnormality of the electrolysis module is detected, prompt information for prompting the electrode abnormality is generated, and the prompt information is sent to the external terminal through the communication module, so that the user of the external terminal can learn about the abnormality of the working electrolysis module in time, and thus the user can repair the working electrolysis module after receiving the prompt information. The external terminal can be a terminal installed with a user application program corresponding to the working electrolysis module.

[0123] In an embodiment, when it is detected that the current abnormality is caused by an abnormality of the power supply, alarm information for prompting the abnormality of the power supply can also be generated, and the alarm information can also be sent to the external terminal through the communication module, so that the user of the external terminal can learn about the abnormality of the power supply in time, and thus the user can know the specific reason for the current abnormality.

[0124] When there are multiple working electrolysis modules, if an electrode abnormality is detected, it is difficult to effectively determine which electrolysis module is abnormal, which leads to difficulty in quickly finding the working electrolysis module with the abnormality for repair. Therefore, in an embodiment, the prompt information includes a unique serial number corresponding to the working electrolysis module.

[0125] In an embodiment, each electrolysis module is pre-provided with a unique serial number. When a preset voltage is applied to at least one of the electrolysis modules to determine it as a working electrolysis module, if an abnormality of a working electrolysis module is detected, the serial number corresponding to the working electrolysis module with the abnormality is added to the prompt information, and the prompt information with the serial number is sent to the external terminal, so that the user of the external terminal can quickly locate the working electrolysis module with the abnormality according to the serial number in the prompt information for repair.

[0126] The electrode detection method of the electrolysis module in the household appliance according to the embodiments of the present application will be further described in detail below Figure 8 The operation schematic diagram of the electrolysis module is shown. In the figure, 1 is a power supply, 2 is a water purification module, 3 is an electrolysis module, 4 is a water inlet of the electrolysis module, 5 is a water outlet of the electrolysis module, and 6 is a control valve.

[0127] When the household appliance is running, power supply 1 is turned on, applying voltage to the water purification module 2 and the electrolysis module 3. At this time, the electrolysis module 3 is in operation. Raw water enters the water purification module 2 through its inlet. After purification, the purified water flows into the electrolysis module 3. The electrolysis module 3 contains high-chlorine water, which, under the action of power supply 1, generates hypochlorite ions to sterilize the soft water flowing into the electrolysis module through inlet 4. The sterilized soft water is then discharged through outlet 5 and provided to the user. During this process, the controller (not shown) continuously monitors the current of the electrolysis module 3 for any abnormalities.

[0128] In one embodiment, if the current of the electrolysis module 3 is normal, the control valve 6 on the inlet 4 and outlet 5 remains open, the inlet 4 and outlet 5 are connected, and the household appliance performs normal soft water sterilization work; if the current of the electrolysis module 3 is abnormal, it is determined that the electrode of the electrolysis module 3 is abnormal.

[0129] In one embodiment, the controller further includes a bacterial detection component 100 disposed on the pipes of the inlet 4 and the outlet 5. When the controller detects an abnormal current, it obtains the sterilization rate based on the bacterial content detected by the bacterial detection component 100; if the sterilization rate is greater than the preset sterilization rate, it is determined that the electrodes of the working electrolysis module are not abnormal; otherwise, it is confirmed that the electrodes of the working electrolysis module are abnormal.

[0130] In one embodiment, the controller further includes a voltage sensor for detecting the voltage applied to the electrolysis module 3. When the controller detects an abnormal current, it detects the voltage received by the voltage sensor. If the voltage is greater than a preset voltage, it determines that the power supply 1 is abnormal; otherwise, it determines that the electrodes of the electrolysis module 3 are abnormal.

[0131] In one embodiment, if the electrodes of the electrolysis module 3 are abnormal or the power supply 1 is abnormal, the control valves 6 on the inlet 4 and outlet 5 are closed to stop water production.

[0132] In one embodiment, such as Figure 9 The diagram shown is an operational schematic of an electrolysis module provided in another embodiment of this application. In this diagram, 11 is a power supply, 12 is a water purification module, 13 is an electrolysis module, 14 is the first inlet of the electrolysis module, 15 is the second inlet of the electrolysis module, 16 is the outlet of the electrolysis module, 17 is a control valve, and 18 is a wastewater pipe. One end of the wastewater pipe 18 is used to connect to wastewater filtered through the electrodialysis membrane stack, and the other end of the wastewater pipe 18 is connected to the first inlet 14.

[0133] When the household appliance is running, the power supply 11 is turned on to apply a voltage to the water purification module 12 and the electrolysis module 13, and the electrolysis module 13 is the working electrolysis module at this time. The raw water enters the water purification module 2 through the water inlet side of the water purification module 2, and the water purification module 2 purifies the raw water to form soft water and waste water. Since the waste water filtered by the water purification module 12 is high-chlorine water, hypochlorite ions can be electrolyzed, so the soft water is received through the first water inlet 14 and the waste water is received through the second water inlet 15, so that the electrolysis module 13 electrolyzes hypochlorite ions from the waste water to sterilize the soft water flowing into the electrolysis module 13 through the first water inlet 14, and then the sterilized soft water is discharged through the water outlet 16. The sterilized water is provided to the user. Since the high-chlorine water entering the electrolysis module 13 is waste water filtered by the water purification module 12, the secondary use of waste water can be realized, and resource waste can be avoided. In this process, the controller (not shown) detects whether the current of the electrolysis module 13 is abnormal in real time.

[0134] In an embodiment, if the current of the electrolysis module 13 is normal, the control valves 17 on the first water inlet 14, the second water inlet 15 and the water outlet 16 remain open, the first water inlet 14, the second water inlet 15 and the water outlet 16 are connected, and the household appliance performs normal soft water sterilization work. If the current of the electrolysis module 13 is abnormal, the electrodes or the power supply 11 of the electrolysis module 13 are detected. If the electrodes of the electrolysis module 13 or the power supply 11 are abnormal, the control valves 17 on the first water inlet 14, the second water inlet 15 and the water outlet 16 are closed, and the water production is stopped.

[0135] In summary, the electrode detection method of the electrolysis module in the household appliance provided in the embodiment of the present application can judge the electrode state of the electrolysis module by the current of the electrolysis module when the electrolysis module starts to work, so as to prevent the sterilization effect of the electrolysis module from being substandard due to electrode abnormality and improve water safety.
