Description

Technical Field

[0001] This invention relates to the field of home appliance technology, specifically to dishwasher control methods, devices, dishwashers, storage media, and program products. Background Technology

[0002] An ozone generator is a device that uses corona discharge to convert oxygen in the air into ozone. Dishwashers can use ozone generators to produce ozone water, which can then be used to sterilize kitchenware.

[0003] Currently, there is a lack of fault detection for ozone generators during the corona discharge process. However, various components in the ozone generator may malfunction during the discharge process. These malfunctions are very likely to affect the discharge efficiency of the discharge electrodes, resulting in a decrease in the ozone concentration in the medium and a weakening of the sterilization effect. Summary of the Invention

[0004] In view of this, the present invention provides a dishwasher control method, device, dishwasher, storage medium and program product to solve the problem that ozone generators in the prior art are prone to failure, affecting the sterilization effect of the dishwasher.

[0005] In a first aspect, the present invention provides a dishwasher control method. The dishwasher includes an ozone generator and a controller. The ozone generator includes a discharge electrode, a ground electrode, a housing, and a glass tube surrounding the discharge electrode. The discharge electrode is used to ionize air in the glass tube to generate ozone, and the glass tube is used to transport the ozone to a medium in the housing. The method is applied to the controller, and the method includes:

[0006] Monitor the feedback voltage of the discharge electrode;

[0007] The ozone generator is determined to be faulty based on the relationship between the feedback voltage and the feedback voltage threshold. The faults of the ozone generator include electrode dry burning, abnormal glass tube operation, and electrode corrosion.

[0008] If the ozone generator malfunctions, a fault alert will be issued.

[0009] This application isolates the discharge electrode from the medium by surrounding it with a glass tube, thereby reducing the rate of corrosion of the discharge electrode by the medium. Furthermore, a controller monitors the feedback voltage of the discharge electrode in real time and compares it with a feedback voltage threshold to determine if the ozone generator is malfunctioning. A fault alert is issued upon detection of a fault, facilitating timely maintenance of the ozone generator and ensuring ozone production efficiency and the sterilization effect of the dishwasher.

[0010] In one optional implementation, determining whether the ozone generator has malfunctioned based on the relationship between the feedback voltage and the feedback voltage threshold includes:

[0011] Determine whether the feedback voltage is greater than the first feedback voltage threshold; the first feedback voltage threshold is the voltage between the discharge electrode and the ground electrode when the storage capacity of the medium in the enclosure is lower than the storage capacity threshold.

[0012] If the feedback voltage is greater than the first feedback voltage threshold, the ozone generator is determined to have an electrode dry-burning fault.

[0013] This application determines whether the ozone generator has experienced electrode dry-burning fault by real-time detection of whether the feedback voltage of the discharge electrode is greater than the first feedback voltage threshold corresponding to the discharge electrode when the medium storage capacity is low, thereby achieving real-time monitoring of electrode dry-burning fault.

[0014] In one optional implementation, determining whether the ozone generator has malfunctioned based on the relationship between the feedback voltage and the feedback voltage threshold further includes:

[0015] Determine whether the feedback voltage is less than the second feedback voltage threshold; the second feedback voltage threshold is the voltage when the discharge electrode is directly connected to the ground electrode through the medium in the box, and the second feedback voltage threshold is less than the first feedback voltage threshold.

[0016] If the feedback voltage is less than the second feedback voltage threshold, the ozone generator is determined to have a glass tube malfunction.

[0017] This application determines whether the ozone generator has experienced a glass tube malfunction by real-time detection of whether the feedback voltage of the discharge electrode is less than the second feedback voltage threshold corresponding to when the discharge electrode is directly connected to the ground electrode through the medium in the housing. This enables real-time monitoring of glass tube malfunctions.

[0018] In one optional implementation, determining whether the ozone generator has malfunctioned based on the relationship between the feedback voltage and the feedback voltage threshold further includes:

[0019] Determine whether the feedback voltage is greater than the third feedback voltage threshold and less than the first feedback voltage threshold; the third feedback voltage threshold is the voltage when the corrosion degree of the discharge electrode is higher than the corrosion degree threshold, and the third feedback voltage threshold is less than the first feedback voltage threshold.

[0020] If the feedback voltage is greater than the third feedback voltage threshold but less than the first feedback voltage threshold, the ozone generator is determined to have an electrode corrosion fault.

[0021] This application determines whether an ozone generator has experienced electrode corrosion failure by real-time detection of whether the feedback voltage of the discharge electrode is greater than the third feedback voltage threshold corresponding to severe corrosion of the discharge electrode and less than the first feedback voltage threshold, thereby achieving real-time monitoring of electrode corrosion failure.

[0022] In one optional embodiment, the dishwasher further includes an adjustable voltage power supply and a transformer, wherein the controller is connected to the primary winding of the transformer via the adjustable voltage power supply, and the secondary winding of the transformer includes an output winding connected to a discharge electrode; the method further includes:

[0023] When the dishwasher is detected to be powered on, a voltage regulation signal is output to the adjustable voltage power supply to control the output winding of the transformer to supply power to the discharge electrode.

[0024] This application utilizes a controller to output a voltage regulation signal to an adjustable voltage power supply, thereby controlling the output winding of the transformer to supply power to the discharge electrodes, thus ionizing the air to produce ozone.

[0025] In one alternative implementation, the method further includes, before issuing a fault alert:

[0026] Stop outputting voltage regulation signals to the adjustable voltage power supply.

[0027] When the ozone generator detects electrode dry burning faults and glass tube malfunctions, the controller quickly cuts off the output of the voltage regulation signal, thereby stopping the corona discharge of the ozone generator and protecting the device from being burned out.

[0028] In one alternative implementation, the dishwasher further includes a voltage detection module, the secondary winding of the transformer further includes a feedback winding, the controller is connected to the feedback winding via the voltage detection module, and the number of turns of the feedback winding is proportional to the number of turns of the output winding.

[0029] Monitoring the feedback voltage of the discharge electrode includes:

[0030] Acquire the voltage detection signal from the voltage detection module;

[0031] The feedback voltage of the discharge electrode is obtained based on the voltage detection signal.

[0032] This application obtains the voltage of the feedback winding by voltage detection signal, and calculates the voltage of the output winding according to the turns ratio between the feedback winding and the output winding, thereby obtaining the feedback voltage of the discharge electrode at this time, and realizing real-time monitoring of the discharge electrode voltage.

[0033] In a second aspect, the present invention provides a dishwasher control device, the dishwasher including an ozone generator and a controller, the ozone generator including a discharge electrode, a ground electrode, a housing, and a glass tube surrounding the discharge electrode, the discharge electrode being used to ionize air in the glass tube to generate ozone, and the glass tube being used to transport the ozone to a medium in the housing; the device is applied to the controller, the device including:

[0034] The acquisition module is used to monitor the feedback voltage of the discharge electrode;

[0035] The processing module is used to determine whether the ozone generator has malfunctioned based on the relationship between the feedback voltage and the feedback voltage threshold; wherein, the malfunctions of the ozone generator include electrode dry burning malfunction, glass tube malfunction, and electrode corrosion malfunction.

[0036] The control module is used to provide fault alerts if the ozone generator malfunctions.

[0037] Thirdly, the present invention provides a dishwasher, comprising an ozone generator and a controller.

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] According to an embodiment of the present invention, a dishwasher is provided, such as Figure 1 As shown, the dishwasher includes an ozone generator 101 and a controller 102, which are connected via a communication line. Wherein, as Figure 2 As shown, the ozone generator 101 includes a discharge electrode, a ground electrode 7, a housing 8, and a glass tube 11. It should be noted that... Figure 2 The discharge electrodes shown include six electrodes: a first electrode 1, a second electrode 2, a third electrode 3, a fourth electrode 4, a fifth electrode 5, and a sixth electrode 6. However, the number of discharge electrodes can be adjusted according to the actual application scenario, and this application is not limited to this.

[0052] And, see again Figure 2A glass tube 11 is arranged around the discharge electrode, thereby isolating the discharge electrode from contact with the medium 9 in the housing 8. The discharge electrode is used to ionize the air in the glass tube 11 to generate ozone, and the glass tube 11 is used to transport the ozone to the medium 9 in the housing 8.

[0053] Specifically, the controller 102 is used to monitor the feedback voltage of the discharge electrode. Based on the relationship between the feedback voltage and the feedback voltage threshold, it determines whether the ozone generator 101 has malfunctioned. If the ozone generator 101 malfunctions, the controller 102 will issue a fault warning.

[0054] The dishwasher provided in this embodiment isolates the discharge electrode from the medium 9 by surrounding it with a glass tube 11, thereby reducing the rate at which the discharge electrode is corroded by the medium. Furthermore, the controller 102 monitors the feedback voltage of the discharge electrode in real time and compares it with a feedback voltage threshold to determine if the ozone generator 101 has malfunctioned. A fault alert is issued when a fault is detected, facilitating timely maintenance of the ozone generator 101 and ensuring ozone generation efficiency and the dishwasher's sterilization effect.

[0055] For details on the specific working principle and control method of controller 102, please refer to the detailed description of the method embodiments below, which will not be repeated here.

[0056] In some embodiments, see again Figure 2 The ozone generator 101 also includes an electrode connection module 10, which is used to mount and connect the discharge electrode and the ground electrode 7.

[0057] In some embodiments, see again Figure 2 The medium 9 in the housing 8 can be tap water, and the ozone generator 101 also includes an air pump (in... Figure 2 (Not shown in the image) The air pump blows the ozone generated by the discharge electrode into the tap water by passing air into the glass tube 11, forming ozone water.

[0058] In some embodiments, such as Figure 3 As shown, the dishwasher also includes an adjustable voltage power supply 103 and a transformer T1. The controller 102 is connected to the primary winding of the transformer T1 via the adjustable voltage power supply 103. The secondary winding of the transformer T1 includes an output winding, which is connected to the ozone generator 101. The connection method between the output winding of the transformer T1 and the ozone generator 101 can be found in [reference needed]. Figure 2 As shown, the output winding of transformer T1 is connected to the discharge electrode and ground electrode 7 of ozone generator 101 respectively. Transformer T1 outputs energy to the discharge electrode, causing the discharge electrode to ionize the air and generate ozone.

[0059] See you again Figure 3The adjustable voltage power supply includes a first adjustable voltage power supply and a second adjustable voltage power supply. The dishwasher also includes a first inductor L1, a second inductor L2, a first switch Q1, a second switch Q2, and a capacitor C1. The first output terminal of the controller 102 is connected to point A of the primary winding of the transformer T1 via the first inductor L1, and the second output terminal of the controller 102 is connected to point B of the primary winding via the second inductor L2. The capacitor C1 is connected between point A and point B of the primary winding. The first inductor L1 and the second inductor L2 can be differential mode inductors, but this application is not limited to this.

[0060] Furthermore, the third output terminal of controller 102 is connected to the control terminal of the first switch Q1. One end of the first switch Q1 is connected to point A of the primary winding, and the other end of the first switch Q1 is grounded. Additionally, the fourth output terminal of controller 102 is connected to the control terminal of the second switch Q2. One end of the second switch Q2 is connected to point B of the primary winding, and the other end of the second switch Q2 is grounded. The first switch Q1 and the second switch Q2 can be switching transistors, triodes, etc., and this application is not limited to these.

[0061] It should be noted that since the corona discharge of the driving discharge electrode is high voltage, transformer T1 is used for isolation, and transformer T1 is a step-up transformer to obtain high voltage through voltage step-up.

[0062] Specifically, see again Figure 3 When the dishwasher needs to work, the entire dishwasher is powered on, the controller 102 is powered on, and the controller 102 inputs voltage adjustment signals to the first adjustable voltage power supply and the second adjustable voltage power supply, so that the first adjustable voltage power supply and the second adjustable voltage power supply work.

[0063] In some embodiments, the controller 102 sends a first drive signal to the first switch Q1 and a second drive signal to the second switch Q2. The first and second drive signals can be alternating pulse signals, thereby controlling the push-pull operation of the first switch Q1 and the second switch Q2 (alternating to be on or off). When the first switch Q1 is on to ground and the second switch Q2 is off, the output voltage of the first adjustable voltage power supply charges the first inductor L1, and the energy charged by the second inductor L2 in the previous cycle enters the primary winding of the transformer T1 from point B in the form of current. Then, when the second switch Q2 is on to ground and the first switch Q1 is off, the output voltage of the second adjustable voltage power supply charges the second inductor L2, and the energy charged by the first inductor L1 in the previous cycle enters the primary winding of the transformer T1 from point A in the form of current. In this way, the first switch Q1 and the second switch Q2 work alternately, so that an alternating current is formed at the primary winding of the transformer T1, and after being stepped up, an alternating high voltage is formed at the secondary winding of the transformer T1.

[0064] In this embodiment, by simultaneously controlling the first switch Q1 and the second switch Q2 to conduct alternately, an alternating voltage is formed in the primary winding of the transformer T1. After being stepped up, an alternating high voltage is formed in the secondary winding of the transformer T1, causing the ozone generator 101 to perform corona discharge.

[0065] In some embodiments, when the corona discharge duration of the ozone generator 101 reaches a preset duration T0, the controller 102 stops outputting the voltage regulation signal, causing the adjustable voltage power supply to stop working, the transformer T1 to stop generating high voltage, and the ozone generator 101 to stop working. The preset duration T0 can be the time required to prepare ozone water of a preset ozone concentration, and can be set according to the actual scenario.

[0066] In some embodiments, see again Figure 3 The dishwasher also includes a voltage detection module 104, and the secondary winding of the transformer T1 includes a feedback winding. The controller 102 is connected to the feedback winding via the voltage detection module 104. The number of turns of the feedback winding is proportional to the number of turns of the output winding.

[0067] Specifically, the number of turns in the feedback winding is proportional to the number of turns in the output winding. The feedback winding provides feedback on the voltage of the output winding in proportion to the number of turns, and this feedback is then sent to the controller 102 via the voltage detection module 104 for processing and control, thereby obtaining the feedback voltage of the discharge electrode. For example, the number of turns in the feedback winding and the number of turns in the output winding can be the same, in which case the voltage of the feedback winding is the feedback voltage of the discharge electrode.

[0068] According to an embodiment of the present invention, a dishwasher control method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0069] This embodiment provides a dishwasher control method, which can be used for, for example Figure 1 The controller 102 shown is, for example, a microcontroller, a microcontroller unit (MCU), etc. Figure 4 This is a flowchart of a dishwasher control method according to an embodiment of the present invention, such as... Figure 4 As shown, the process includes the following steps:

[0070] Step S401: Monitor the feedback voltage of the discharge electrode.

[0071] Specifically, the controller monitors the feedback voltage of the discharge electrode in real time to determine whether the ozone generator has malfunctioned.

[0072] Step S402: Determine whether the ozone generator has malfunctioned based on the relationship between the feedback voltage and the feedback voltage threshold.

[0073] Specifically, ozone generator malfunctions include electrode dry burning, abnormal glass tube operation, and electrode corrosion. During the corona discharge process of the ozone generator, the surface of the discharge electrode reacts chemically with the surrounding medium, easily leading to material corrosion or oxidation. The discharge electrode generates localized high temperatures during discharge, causing material melting or evaporation, resulting in physical losses. When the discharge electrode is arcing, the high temperature of the arc discharge causes rapid vaporization or melting of the electrode surface material, forming pits or depressions, thus reducing the effective area of ​​the discharge electrode. All of these factors contribute to electrode corrosion. Excessive corrosion of the discharge electrode leads to a rough surface or the formation of an oxide layer, increasing the contact resistance between the discharge electrode and the ground electrode, reducing conductivity, and gradually eroding the electrode surface, altering its geometry, affecting the electric field distribution, and consequently impacting the discharge efficiency and uniformity. Ultimately, this results in a decrease in ozone concentration in the ozone water and a weakened sterilization effect.

[0074] In this embodiment, during the discharge process, the formation of an oxide layer on the electrode surface due to electro-corrosion or the reduction in electrode length both increase the resistance between the discharge electrode and the ground electrode, thus raising the feedback voltage of the discharge resistor. When the glass tube breaks or the gas pump malfunctions, the discharge electrode comes into direct contact with the medium, causing a decrease in the feedback voltage of the discharge resistor. Similarly, a low storage capacity of the medium in the chamber increases the resistance between the discharge electrode and the ground electrode, further raising the feedback voltage of the discharge resistor. Therefore, by using extensive experimental data, the feedback voltage threshold corresponding to the discharge electrode when the ozone generator malfunctions is obtained. Based on the relationship between the feedback voltage and the feedback voltage threshold, it can be determined whether the ozone generator has malfunctioned.

[0075] Step S403: If the ozone generator malfunctions, issue a fault alert.

[0076] Specifically, after detecting a malfunction in the ozone generator, the controller issues a fault alert to remind the user to repair the ozone generator in a timely manner.

[0077] The dishwasher control method provided in this embodiment isolates the discharge electrode from the medium by surrounding it with a glass tube, thereby reducing the rate of corrosion of the discharge electrode by the medium. Furthermore, the controller monitors the feedback voltage of the discharge electrode in real time and compares it with a feedback voltage threshold to determine if the ozone generator is malfunctioning. A fault alert is issued when a fault is detected, facilitating timely maintenance of the ozone generator and ensuring ozone production efficiency and the dishwasher's sterilization effect.

[0078] This embodiment provides a dishwasher control method, which can be used for, for example Figure 1 The controller 102 shown is, for example, a microcontroller, a microcontroller unit (MCU), etc. Figure 5 This is a flowchart of a dishwasher control method according to an embodiment of the present invention, such as... Figure 5 As shown, the process includes the following steps:

[0079] Step S501: Monitor the feedback voltage of the discharge electrode.

[0080] Specifically, step S501 includes:

[0081] Step S5011: Obtain the voltage detection signal from the voltage detection module.

[0082] Specifically, see again Figure 3 When the dishwasher is preparing ozone water, the feedback winding of transformer T1 feeds back the voltage of the output winding in proportion to the turns ratio of the feedback winding to the output winding. The voltage is then fed back to the controller 102 by the voltage detection module 104. The controller 102 receives the voltage detection signal fed back by the voltage detection module 104 and processes and controls the voltage detection signal.

[0083] Step S5012: Obtain the feedback voltage of the discharge electrode based on the voltage detection signal.

[0084] Specifically, the controller 102 obtains the voltage V0 of the feedback winding based on the voltage detection signal, and calculates the voltage of the output winding, i.e., the feedback voltage V of the discharge electrode, according to the turns ratio of the feedback winding to the output winding. For example, if the turns ratio of the feedback winding to the output winding is N, then the ratio between the voltage V0 of the feedback winding and the voltage of the output winding is also N.

[0085] In this embodiment, the voltage of the feedback winding is obtained by voltage detection signal, and the voltage of the output winding is calculated according to the turns ratio between the feedback winding and the output winding, thereby obtaining the feedback voltage of the discharge electrode at this time and realizing real-time monitoring of the discharge electrode voltage.

[0086] Step S502: Determine whether the ozone generator has malfunctioned based on the relationship between the feedback voltage and the feedback voltage threshold.

[0087] Specifically, step S502 above includes:

[0088] Step S5021: Determine whether the feedback voltage is greater than the first feedback voltage threshold. If the feedback voltage is greater than the first feedback voltage threshold, then determine that the ozone generator has an electrode dry burning fault.

[0089] Specifically, the first feedback voltage threshold V1 is the voltage between the discharge electrode and the ground electrode when the storage capacity of the medium in the enclosure is lower than the storage capacity threshold. It should be noted that the storage capacity threshold can be set according to the actual application scenario.

[0090] In this embodiment, when there is no medium, such as tap water, in the ozone generator, the resistance between the discharge electrode and the ground electrode increases, causing the feedback voltage of the discharge electrode to rise. When the feedback voltage V at this time is detected to be greater than the first feedback voltage threshold V1 corresponding to the discharge electrode when the medium storage capacity is low, it indicates that the discharge electrode is dry-burning, and the ozone generator is determined to have an electrode dry-burning fault.

[0091] In this embodiment of the application, the ozone generator is judged to have an electrode dry-burning fault by detecting in real time whether the feedback voltage of the discharge electrode is greater than the first feedback voltage threshold corresponding to the discharge electrode when the medium storage capacity is low, thereby realizing real-time monitoring of electrode dry-burning fault.

[0092] Step S5022: Determine whether the feedback voltage is less than the second feedback voltage threshold. If the feedback voltage is less than the second feedback voltage threshold, determine that the ozone generator has a glass tube malfunction.

[0093] Specifically, the second feedback voltage threshold V2 is the voltage when the discharge electrode is directly connected to the ground electrode through a medium (such as water) in the enclosure. The second feedback voltage threshold V2 is less than the first feedback voltage threshold V1. It should be noted that the second feedback voltage threshold V2 can be set according to the actual scenario.

[0094] Specifically, when the ozone generator experiences a glass tube malfunction, such as a broken glass tube or a stopped air pump, the discharge electrode will come into direct contact with the medium in the housing, forming a direct circuit with the ground electrode through the medium. At this point, the resistance between the two decreases significantly, causing a drop in the voltage between the output windings, i.e., a decrease in the feedback voltage of the discharge electrode. When the detected feedback voltage V of the discharge electrode is less than the second feedback voltage threshold V2, it indicates a broken glass tube or a malfunction of the air pump, thus determining that the ozone generator has experienced a glass tube malfunction.

[0095] In this embodiment of the application, the ozone generator is judged to have a glass tube malfunction by detecting in real time whether the feedback voltage of the discharge electrode is less than the second feedback voltage threshold corresponding to when the discharge electrode is directly connected to the ground electrode through the medium in the box, thereby realizing real-time monitoring of glass tube malfunction.

[0096] Step S5023: Determine whether the feedback voltage is greater than the third feedback voltage threshold and less than the first feedback voltage threshold. If the feedback voltage is greater than the third feedback voltage threshold and less than the first feedback voltage threshold, then determine that the ozone generator has an electrode corrosion fault.

[0097] Specifically, the third feedback voltage threshold V3 is the voltage at which the corrosion degree of the discharge electrode exceeds the corrosion degree threshold. The third feedback voltage threshold V3 is less than the first feedback voltage threshold V1, and greater than the second feedback voltage threshold V2. When the feedback voltage V detected by the discharge electrode is greater than the third feedback voltage threshold V3 but less than the first feedback voltage threshold V1, it indicates severe electrode corrosion, and the ozone generator is determined to have experienced an electrode corrosion failure. It should be noted that the corrosion degree threshold and the third feedback voltage threshold V3 can be set according to the actual application scenario.

[0098] It should be noted that, under normal circumstances, the feedback voltage V of the discharge electrode will gradually increase with the time and number of times the dishwasher produces ozone water. This is because during the discharge process, the electro-corrosion of the discharge electrode, the formation of an oxide layer on the surface of the discharge electrode, or the reduction in the length of the discharge electrode will increase the resistance between the discharge electrode and the ground electrode, thereby increasing the voltage of the output winding of transformer T1.

[0099] This application embodiment determines whether the ozone generator has experienced electrode corrosion failure by real-time detection of whether the feedback voltage of the discharge electrode is greater than the third feedback voltage threshold corresponding to severe corrosion of the discharge electrode and less than the first feedback voltage threshold, thereby achieving real-time monitoring of electrode corrosion failure.

[0100] Step S503: If the ozone generator malfunctions, issue a fault alert.

[0101] Specifically, when the dishwasher is detected to be powered on, the controller outputs a voltage regulation signal to the adjustable voltage power supply to control the output winding of the transformer to supply power to the discharge electrodes, thereby ionizing the air to produce ozone.

[0102] In some embodiments, when the controller detects an electrode dry-burning fault or a glass tube malfunction in the ozone generator, the controller stops outputting a voltage regulation signal to the adjustable voltage power supply. At this time, the controller quickly cuts off the output of the voltage regulation signal, causing the corona discharge of the ozone generator to stop, thereby protecting the device from being burned out. At the same time, a fault signal is output to remind the user.

[0103] In some alternative implementations, when the controller detects an electrode corrosion failure in the ozone generator, it outputs a fault signal to remind the user to replace the electrode in a timely manner.

[0104] The dishwasher control method provided in this embodiment determines the fault status of the ozone generator by real-time monitoring of the feedback voltage of the discharge electrode inside the ozone generator. When the feedback voltage of the discharge electrode exceeds the reliable range, the user is promptly alerted to take action on the dishwasher, ensuring the efficiency of ozone water production and improving the reliability of the dishwasher's operation. Furthermore, it can solve the problem of electrode dry burning and prevent transformer insulation breakdown that could lead to the collapse of the discharge system.

[0105] The dishwasher control scheme of the present invention will be described in detail below with reference to a specific application example.

[0106] like Figure 6 As shown, after the ozone generator starts working, the feedback voltage V of the discharge electrode is monitored.

[0107] Next, it is determined whether the feedback voltage V of the discharge electrode is less than the second feedback voltage threshold V2. When the feedback voltage V of the discharge electrode is detected to be less than the second feedback voltage threshold V2, it indicates that the glass tube is broken or the air pump is malfunctioning. At this time, the controller stops outputting the voltage regulation signal and reports a water leakage fault to remind the user.

[0108] When the feedback voltage V is detected to be not less than the second feedback voltage threshold V2, it is determined whether the feedback voltage V is greater than the third feedback voltage threshold V3. If the feedback voltage V is not greater than the third feedback voltage threshold V3, it indicates that the ozone generator is working normally; if the feedback voltage V is greater than the third feedback voltage threshold V3, it is further determined whether the feedback voltage V is less than the first feedback voltage threshold V1.

[0109] When the detected feedback voltage V is greater than the third feedback voltage threshold V3 and less than the first feedback voltage threshold V1, it indicates that the electrode corrosion is severe. At this time, the controller reminds the user to replace the electrode in time.

[0110] When the feedback voltage V is detected to be greater than the first feedback voltage threshold V1, it indicates that the electrode is dry-burning. At this time, the controller quickly cuts off the output of the voltage regulation signal, so that the corona discharge of the ozone generator stops, thereby protecting the device from being burned out. At the same time, a dry-burning fault is reported to remind the user.

[0111] This embodiment also provides a dishwasher control device for implementing the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0112] This embodiment provides a dishwasher control device. The dishwasher includes an ozone generator and a controller. The ozone generator includes a discharge electrode, a ground electrode, a housing, and a glass tube surrounding the discharge electrode. The discharge electrode is used to ionize the air in the glass tube to generate ozone, and the glass tube is used to transport the ozone to a medium in the housing.
