Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and particularly relates to a dishwasher and a control method thereof. Background Art

[0002] Currently, after the dishwasher finishes washing the tableware, a disinfection process is usually carried out on the washed tableware, such as rinsing with sodium hypochlorite solution or disinfecting with ozone. However, traditional dishwashers always dispense a fixed amount of disinfectant or introduce a fixed amount of disinfection gas during the disinfection program, resulting in either too little or too much disinfection medium, thus failing to effectively disinfect different quantities of tableware. Summary of the Invention

[0003] In view of this, the present application provides a dishwasher and a control method thereof to solve the technical problem that the existing dishwashers cannot effectively disinfect different quantities of tableware.

[0004] In a first aspect, the present application provides a dishwasher, which includes:

[0005] An inner container, provided with a washing space and a washing component located in the washing space;

[0006] A disinfectant generator, communicated with the inner container; the disinfectant generator is used to generate disinfectant;

[0007] A controller, connected to the washing component and the disinfectant generator;

[0008] The washing program input into the controller corresponds to the tableware to be washed, and the disinfectant prepared by the disinfectant generator corresponds to the washing program.

[0009] Advantageous Effects: In the embodiments of the present invention, the washing program corresponds to the tableware to be washed, enabling the user to personally select the washing program according to the quantity, weight, or volume of the tableware to be washed. For example, when there are more tableware to be washed, the strong washing mode can be selected; when there are fewer tableware to be washed, the quick washing mode can be selected; when the quantity of the tableware to be washed is normal, the normal washing mode can be selected. Of course, the volume and concentration of the disinfectant corresponding to different washing programs are also different. For example, when in the strong washing mode, a larger amount and higher concentration of disinfectant are prepared; when in the quick washing mode, a smaller amount and lower concentration of disinfectant are prepared; when in the normal washing mode, the disinfectant is at a normal level. Of course, the dishwasher can automatically identify the above parameters of the tableware to be washed in the inner container, such as quantity, weight, or volume, and thus can automatically select the corresponding washing program. In this way, the concentration and volume of the prepared disinfectant can be matched with the actual situation of the tableware to be washed, so as to effectively disinfect different quantities of tableware with the disinfectant, and at the same time, the intelligent preparation of disinfectant by the dishwasher is realized, and there will be no situation of resource waste or ineffective disinfection.

[0010] In an alternative embodiment, the disinfectant generator is an ozone reactor.

[0011] In an alternative embodiment, the ozone reactor includes:

[0012] A box body, provided with a water inlet assembly and a drainage assembly, the water inlet assembly is connected to an external water source, and the drainage assembly is communicated with the inner container;

[0013] A gas supply assembly, arranged in the box body; one end of the gas supply assembly is connected to an external gas source, and the other end of the gas supply assembly is communicated with the interior of the box body;

[0014] A cathode, arranged in the box body and connected to a power supply assembly;

[0015] An anode, arranged in the gas supply assembly and connected to the power supply assembly;

[0016] The water inlet assembly, the drainage assembly, the gas supply assembly, and the power supply assembly are all connected to a controller.

[0017] In an alternative embodiment, the ozone reactor further includes:

[0018] A liquid level detection assembly, arranged in the box body and connected to the controller; the liquid level detection assembly is used to detect the actual liquid level of the water in the box body.

[0019] Beneficial effects: In the embodiment of the present invention, by setting the liquid level detection assembly, the actual liquid level of the water in the box body can be detected in real time. In this embodiment, the water is not only a solvent for dissolving ozone, but also a conductive medium, which can evenly disperse charges, reduce the local high electric field intensity, thereby reducing the instability during the high-voltage discharge process. The conductivity of the water helps to smooth the current fluctuation and reduce the transient current impact on the power supply assembly. Therefore, the liquid level detection assembly can ensure that the solvent is within the normal range during the production of ozone water, and can also ensure the overall stability of the equipment during the discharge preparation of ozone.

[0020] In an alternative embodiment, the gas supply assembly includes:

[0021] An air pump, connected to an external gas source;

[0023] A gas delivery member, one end of the gas delivery member is communicated with the insulating tube, and the other end of the gas delivery member is communicated with the interior of the box body.

[0024] In an alternative embodiment, the insulating tube is a glass tube.

[0025] In an alternative embodiment, during ionization, the bottom of the glass tube is adapted to contact the water in the box body, and the cathode contacts the water in the box body.

[0026] In an alternative embodiment, the gas delivery member is a through hole formed at the bottom of the insulating tube.

[0027] Beneficial effects: In the embodiment of the present invention, by forming a through hole at the bottom of the insulating tube, during the preparation of ozone, since the air pump continuously supplies air into the insulating tube, the air will blow out the water that is about to enter the insulating tube through the through hole, so the water cannot enter the insulating tube through the through hole to contact the anode. Moreover, the anode is at a certain distance from the through hole at the bottom of the insulating tube, so even if a small amount of water enters, it cannot contact the anode.

[0028] Meanwhile, while the air pump supplies air into the insulating tube, the ozone generated by the anode can be directly blown into the water, increasing the contact time and contact area between the ozone and the water, enabling the ozone to directly dissolve in the water to form ozone water, and improving the preparation efficiency of the ozone water.

[0029] In an alternative embodiment, the gas supply assembly further includes:

[0030] A gas volume detection module for detecting the intake air volume of the air pump.

[0031] Beneficial effects: In the embodiment of the present invention, by providing a gas volume detection module, it can be used to detect whether the air pump is operating normally and whether the gas supply assembly is supplying gas normally. When the detected intake air volume of the air pump is abnormal, the power supply assembly can stop supplying power to the anode and the cathode, thereby ending the process of ionizing to produce ozone, preventing water from entering the insulating tube through the through hole to contact the anode, and thus ensuring the overall safety of the device.

[0032] In an alternative embodiment, the power supply assembly includes:

[0033] A transformer having a first side and a second side; the second side is connected to the cathode and the anode;

[0034] A voltage generation circuit connected to the first side; the voltage generation circuit is used to generate an alternating voltage.

[0037] A second inductor, one end of the second inductor is connected to the second output terminal, and the other end of the second inductor is connected to the second end of the first side;

[0038] A first switch, a first end of the first switch is connected to a first end of the first side, a second end of the first switch is grounded, and a control end of the first switch is connected to the first signal terminal;

[0039] A second switch, a first end of the second switch is connected to a second end of the first side, a second end of the second switch is grounded, and a control end of the second switch is connected to the second signal terminal;

[0040] When the first switch is turned on and the second switch is turned off, the first inductor stores energy and the second inductor releases energy; when the second switch is turned on and the first switch is turned off, the first inductor releases energy and the second inductor stores energy.

[0041] In a second aspect, the present application provides a control method for a dishwasher, and the control method includes:

Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

For example, it can be fixedly connected, detachably connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediate medium, and can also be the connection inside two elements.

[0066] Currently, after the dishwasher finishes washing the tableware, a disinfection process is usually carried out on the washed tableware. For example, sodium hypochlorite solution is introduced for rinsing, or ozone is introduced for disinfection. However, traditional dishwashers always dispense a fixed amount of disinfectant or introduce a fixed amount of disinfection gas during the disinfection program, resulting in either too little or too much disinfection medium, thus failing to effectively disinfect different quantities of tableware.

[0067] In view of this, the present application provides a dishwasher and a control method for the dishwasher to solve the technical problem that the existing dishwashers cannot effectively disinfect different quantities of tableware.

[0068] An embodiment of the present application proposes a dishwasher. The following combines Figures 1 to 3 , to describe the embodiments of the present application.

[0069] As Figures 1 to 3 shown, according to an embodiment of the present application, on the one hand, the present application provides a dishwasher, which includes: an inner container, a disinfectant generator 1, and a controller 3.

[0070] Specifically, in this embodiment, the inner tank is disposed inside the dishwasher. The inner tank itself has a cleaning space and a cleaning component located in the cleaning space. During actual use, the user can directly put the tableware to be washed into the inner tank, and then after pressing the corresponding cleaning program, the cleaning component will clean the tableware to be washed in the inner tank. For the cleaning program, the cleaning program corresponds to the tableware to be washed. When selecting the cleaning program, it can be manually selected by the user or automatically selected by the dishwasher. That is to say, the user can select a suitable cleaning program according to the quantity, weight or volume of the tableware to be washed. Or, the dishwasher can automatically select the cleaning program according to the quantity, weight or volume of the tableware to be washed. Of course, when the dishwasher automatically selects the cleaning program, the dishwasher can automatically identify the specific situation of the tableware to be washed in the inner tank, such as the quantity, weight or volume of the tableware to be washed, so as to automatically select the corresponding cleaning program.

[0071] During the actual cleaning process, when there are more tableware to be washed, the user or the dishwasher itself selects the strong cleaning mode. When there are fewer tableware to be washed, the quick cleaning mode is selected. When the quantity of the tableware to be washed is normal, the normal cleaning mode is selected. Of course, the volume and concentration of the disinfectant solution corresponding to different cleaning programs are also different. For example, in the strong cleaning mode, since there are more tableware, more disinfectant solution is prepared and the concentration is higher. In this way, the tableware can be effectively disinfected by the disinfectant solution. In the quick cleaning mode, since there are fewer tableware, less disinfectant solution is prepared and the concentration is lower. In this way, waste of the disinfectant solution can be avoided, and the preparation time of the disinfectant solution can be shortened, improving the overall cleaning efficiency of the dishwasher. In the normal cleaning mode, the disinfectant solution can be prepared at the normal level.

[0072] Of course, multiple gears of cleaning modes can also be set to conform to the tableware to be washed in different situations, so that the disinfectant solution can better match the tableware to be washed. This embodiment is only an example of the specific mode of the cleaning program, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0073] Further, in this embodiment, the disinfectant generator 1 is communicated with the inner tank, and the disinfectant generator 1 is used to generate the disinfectant solution. For the specific type of the disinfectant solution, for example, it can be sodium hypochlorite solution, acidic electrolyzed water, sodium percarbonate solution, quaternary ammonium salt disinfectant. Of course, this embodiment is only an example of the specific type of the disinfectant solution, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0074] Further, in this embodiment, the controller 3 is connected to the cleaning component and the disinfectant generator 1. The controller 3 is disposed in the dishwasher. For the way for the user to input the cleaning program to the controller 3, the user can press the buttons on the operation panel of the dishwasher. Different buttons correspond to different cleaning programs. The operation panel is communicatively connected to the controller 3. After the user presses the corresponding button, the controller 3 can obtain the corresponding signal, so as to operate the disinfectant generator 1 to start preparing the disinfectant.

[0075] As can be seen from the above, in this embodiment, the cleaning program input to the controller 3 corresponds to the tableware to be washed, and the disinfectant prepared by the disinfectant generator 1 corresponds to the cleaning program.

[0076] After the disinfectant is prepared, the controller 3 controls the disinfectant generator 1 to stop preparing, and discharges the prepared disinfectant into the inner tank of the dishwasher.

[0077] With such a setting, in the embodiment of the present invention, the cleaning program corresponds to the tableware to be washed, so that the user can personally select the cleaning program according to the quantity, weight or volume of the tableware to be washed. For example, when there are more tableware to be washed, select the strong cleaning mode; when there are fewer tableware to be washed, select the quick cleaning mode; when the quantity of the tableware to be washed is normal, select the normal cleaning mode. Of course, the volume and concentration of the disinfectant corresponding to different cleaning programs are also different. For example, in the strong cleaning mode, the amount of the prepared disinfectant is more and the concentration is higher; in the quick cleaning mode, the amount of the disinfectant is less and the concentration is lower; in the normal cleaning mode, the disinfectant is at a normal level. Of course, the dishwasher can automatically identify the above parameters of the tableware to be washed in the inner tank, such as quantity, weight or volume, so as to automatically select the corresponding cleaning program. In this way, the concentration and volume of the prepared disinfectant can be matched with the actual situation of the tableware to be washed, so that the disinfectant can effectively disinfect different quantities of tableware, and at the same time, the intelligent preparation of the disinfectant by the dishwasher is realized, and the situation of resource waste or ineffective disinfection will not occur.

[0078] Further, in an optional implementation manner, the disinfectant generator 1 is an ozone reactor. The ozone reactor usually generates ozone by high-voltage ionization of air, and then makes ozone water by dissolving ozone in water.

[0079] Further, in an optional implementation manner, as Figure 1 shown, the ozone reactor includes a box body 11, a water inlet component, a water drainage component, a power supply component 2, a gas supply component and an ionization component. The water inlet component, the water drainage component, the gas supply component and the power supply component 2 are all connected to the controller 3.

[0080] Specifically, in this embodiment, a water inlet assembly and a drainage assembly are provided in the cabinet 11. The water inlet assembly is connected to an external water source, and the drainage assembly is communicated with the inner tank. That is to say, when tap water is required to prepare ozone in the cabinet 11 and to improve the discharge stability of the device, the water inlet assembly is started to supply water into the cabinet 11, and the specific water inflow is controlled by the controller 3, so that the water inflow can be matched with the cleaning program. For the drainage assembly, after the ozone reactor finishes preparing the disinfectant solution, the drainage assembly can be automatically opened by the controller 3, so that the disinfectant solution can be discharged into the inner tank to disinfect the tableware in the inner tank.

[0081] Further, in this embodiment, the air supply assembly is provided in the cabinet 11. One end of the air supply assembly is connected to an external air source, and the other end of the air supply assembly is communicated with the inside of the cabinet 11. Before starting ionization, ventilation is started to ensure that the ionization assembly can normally perform high-voltage ionization on the air in the air supply assembly.

[0082] Further, in this embodiment, the ionization assembly includes a cathode 12 and an anode 13. As Figure 1 shown, the cathode 12 is provided in the cabinet 11 and is connected to the power supply assembly 2. The anode 13 is provided in the air supply assembly and is connected to the power supply assembly 2. That is to say, the power supply assembly 2 supplies power to both the anode 13 and the cathode 12 at the same time. Of course, the anode 13 is connected to the anode 13 of the power supply assembly 2, and the cathode 12 can be directly grounded or connected to the grounding terminal of the power supply assembly 2, so as to form a discharge circuit. During the ionization process, the anode 13 can ionize the air to generate ozone. The ozone is then output to the inside of the cabinet 11 by the air supply assembly along with the internal air, so that the ozone can be dissolved in the water in the cabinet 11 to generate ozone water.

[0083] Facing different cleaning programs, the controller 3 controls the water inlet assembly to inject water into the cabinet 11 that matches the cleaning program. Then the controller 3 controls the power supply assembly 2 to start power supply, so that the ionization assembly is started. The power supply time of the power supply assembly 2 matches the cleaning program. For example, in the strong cleaning mode, the power supply time is longer, the ionization duration of the ionization assembly is longer, the amount of ozone generated is more, and the concentration of ozone water is higher. Similarly, when the fast cleaning mode is selected, the power supply time is shorter, the ionization duration of the ionization assembly is shorter, the amount of ozone generated is less, and the concentration of ozone water is lower.

[0084] Further, in an optional embodiment, the ozone reactor further includes a liquid level detection component 17. The liquid level detection component 17 is disposed in the box body 11 and connected to the controller 3. The liquid level detection component 17 is used to detect the actual liquid level of the water in the box body 11. When the liquid level detection component 17 detects that the actual liquid level is lower than the preset liquid level, the controller 3 controls the water inlet component to start and start water inlet; when the liquid level detection component 17 detects that the actual liquid level is equal to the preset liquid level, the controller 3 controls the water inlet component and the drain component to stop operating, so as to stop water inlet and drainage. When the liquid level detection component 17 detects that the actual liquid level is greater than the preset liquid level, the controller 3 controls the drain component to start draining.

[0085] For the type of the liquid level detection component 17, it can be a water level detection probe, a water level float, or other liquid level detection components 17 such as a water level gauge. Of course, this embodiment is only an example of the liquid level detection component 17, but it is not limited thereto. Those skilled in the art can make changes according to the actual situation as long as the same technical effects can be achieved.

[0086] With such a setting, in the embodiment of the present invention, by setting the liquid level detection component 17, the actual liquid level of the water in the box body 11 can be detected in real time. In this embodiment, the water is not only a solvent for dissolving ozone, but also a conductive medium, which can evenly disperse charges, reduce the local high electric field intensity, and thus reduce the instability during the high-voltage discharge process. The conductivity of the water helps to smooth the current fluctuation and reduce the transient current impact on the power supply component 2. Therefore, the liquid level detection component 17 can ensure that the solvent is within the normal range during the production process of ozone water, and can also ensure the overall stability of the equipment during the process of discharging to prepare ozone.

[0087] Further, in an optional embodiment, the gas supply component includes an air pump, an insulating tube, and a gas delivery member.

[0088] Specifically, in this embodiment, the air inlet end of the air pump is connected to an external gas source. The insulating tube is disposed in the box body 11 and communicated with the air outlet end of the air pump. The anode 13 is disposed in the insulating tube. Of course, in this embodiment, the material used for the insulating tube can ensure that it will not be damaged during high-voltage ionization. Further, one end of the gas delivery member is communicated with the insulating tube, and the other end of the gas delivery member is communicated with the inside of the box body 11.

[0089] Further, in an optional embodiment, the insulating tube is a glass tube 15.

[0090] Further, in an optional embodiment, during ionization, the bottom of the glass tube 15 is adapted to contact the water in the box body 11. During the ionization operation process, the cathode 12 contacts the water in the box body 11.

[0091] During ionization, the anode 13 and the cathode 12 inserted into water can be regarded as two conductors, and the glass tube 15 serves as an insulating medium between them, conforming to the basic structural characteristics of the capacitor 225. In this case, when a voltage is applied between the anode 13 and the cathode 12, charges will accumulate on the anode 13 and the cathode 12, just as charges accumulate on the plates of a traditional capacitor 225.

[0092] Specifically, since the glass tube 15 has good insulation performance and can prevent current from directly passing between the anode 13 and the cathode 12, charges can only accumulate on the surfaces of the anode 13 and the cathode 12, and no conductive path will be formed inside the glass tube 15. This characteristic is consistent with the role of the insulating medium in the capacitor 225. The presence of the insulating medium enables the capacitor 225 to store charges, and the glass tube 15 plays a similar role here. It separates the anode 13 from the water, and the water can be regarded as the conductive part connected to the cathode 12, thus ensuring that charges can form a stable electric field between the anode 13 and the cathode 12, and further realizing the storage of charges.

[0093] For water, water is a conductive medium and can conduct charges. When the anode 13 is inserted into water through the glass tube 15, the water can form a conductive path with the cathode 12 and the surrounding water, enabling charges to accumulate and distribute on one side of this "capacitor 225 structure". At the same time, due to the conductivity of water, it can quickly adjust the charge distribution under the action of an electric field, enhancing the performance of the structure similar to the capacitor 225. For example, when the voltage changes, the water can respond quickly and help the charges redistribute, which is similar to the characteristic of the capacitor 225 adjusting the charge distribution according to the voltage change in the circuit.

[0094] When a voltage is applied between the anode 13 and the cathode 12, an electric field will be formed between the anode 13, the glass tube 15 and the water. The existence of the electric field is the basis for the capacitor 225 to store energy. In this structure similar to the capacitor 225, the electric field is distributed inside and outside the glass tube 15. The electric field inside the glass tube 15 is relatively stable, and outside, due to the conductivity of water, the electric field will diffuse and distribute in the water. This way of forming and distributing the electric field is consistent with the principle of the traditional capacitor 225 forming an electric field between the plates and storing energy.

[0095] Therefore, as a conductive medium, water can evenly disperse charges, reduce the local high electric field intensity, thereby reducing the instability of corona discharge. The conductivity of water helps to smooth the current fluctuation and reduce the transient current impact on the power supply component 2.

[0096] Furthermore, in an alternative embodiment, as Figure 1As shown, a connection module 14 can also be provided on the box body 11. The connection module 14 can act as the cover plate of the box body 11, and can also play the role of energizing and fixing the anode 13 and the cathode 12. Electric connection components corresponding to the anode 13 and the cathode 12 are provided on the connection module 14. The power supply assembly 2 can be arranged outside the box body 11 and then connected to the electric connection components through wires, so as to supply power to the cathode 12 and the anode 13.

[0097] Further, in an alternative embodiment, the gas delivery member is a through hole 16 opened at the bottom of the insulating tube.

[0098] With such a setting, in the embodiment of the present invention, by opening the through hole 16 at the bottom of the insulating tube, during the preparation of ozone, since the air pump continuously ventilates the insulating tube, the air will blow out the water that is about to enter the insulating tube through the through hole 16, so the water cannot enter the insulating tube through the through hole 16 to contact the anode 13. Moreover, there is a certain distance between the anode 13 and the through hole 16 at the bottom of the insulating tube. Even if a small amount of water enters, it cannot contact the anode 13.

[0099] At the same time, while the air pump ventilates the insulating tube, the ozone generated by the anode 13 can be directly blown into the water, which increases the contact time and contact area between the ozone and the water, enables the ozone to directly dissolve in the water to form ozone water, and improves the preparation efficiency of the ozone water.

[0100] Further, in an alternative embodiment, the gas supply assembly further includes a gas volume detection module for detecting the intake air volume of the air pump.

[0101] With such a setting, in the embodiment of the present invention, by providing the gas volume detection module, it can be used to detect whether the air pump is operating normally and whether the gas supply assembly is supplying gas normally. When the detected intake air volume of the air pump is abnormal, the power supply assembly 2 can stop supplying power to the anode 13 and the cathode 12, thereby ending the process of ionizing to produce ozone, preventing water from entering the insulating tube through the through hole 16 to contact the anode 13, and further ensuring the overall safety of the device.

[0102] Further, in an alternative embodiment, the power supply assembly 2 includes a transformer 21 and a voltage generation circuit 22.

[0103] Specifically, in the embodiment of the present invention, the transformer 21 is provided with a first side and a second side, and the second side is connected to the cathode 12 and the anode 13. The voltage generating circuit 22 is connected to the first side, and the voltage generating circuit 22 is used to generate an alternating voltage. After generating an initial voltage, the voltage generating circuit 22 is boosted by the transformer 21 to form a high voltage capable of ionizing air to generate ozone. The transformer 21 can also be used as an isolation. Of course, in this embodiment, the specific structure of the voltage generating circuit 22 is not limited, and those skilled in the art can change it according to the actual situation as long as it can generate an alternating voltage.

[0104] Further, in an alternative embodiment, as Figure 2 shown, the voltage generating circuit 22 includes a first inductor 221, a second inductor 222, a first switch 223, and a second switch 224.

[0105] Specifically, in this embodiment, the controller 3 is provided with a first output terminal, a second output terminal, a first signal terminal, and a second signal terminal. The controller 3 can control the working duration of the power supply assembly 2, thereby controlling the duration of the ionization assembly for ionizing air, and further controlling the amount of ozone generated by ionization and the concentration of ozone water. Further, the first output terminal and the second output terminal of the controller 3 are used to output voltages to charge the first inductor 221 and the second inductor 222. Of course, the first output terminal and the second output terminal can be respectively connected to the first adjustable power supply 226 and the second adjustable power supply 227 to output adjustable voltages. Further, the first signal terminal and the second signal terminal of the controller 3 are used to control the conduction and disconnection of the first switch 223 and the second switch 224.

[0106] Further, in this embodiment, one end of the first inductor 221 is connected to the first output terminal, and the other end of the first inductor 221 is connected to the first end of the first side. One end of the second inductor 222 is connected to the second output terminal, and the other end of the second inductor 222 is connected to the second end of the first side.

[0107] Further, in this embodiment, the first end of the first switch 223 is connected to the first end of the first side, the second end of the first switch 223 is grounded, and the control end of the first switch 223 is connected to the first signal terminal. The first end of the second switch 224 is connected to the second end of the first side, the second end of the second switch 224 is grounded, and the control end of the second switch 224 is connected to the second signal terminal.

[0108] During the actual working process, the first switch 223 and the second switch 224 perform push-pull operation. That is, when the first switch 223 is turned on and the second switch 224 is turned off, the first inductor 221 stores energy and the second inductor 222 releases energy, causing a positive voltage to be generated on the first side of the transformer 21. When the second switch 224 is turned on and the first switch 223 is turned off, the first inductor 221 releases energy and the second inductor 222 stores energy, causing a negative voltage to be generated on the first side of the transformer 21.

[0109] Therefore, by alternately turning on and off the first switch 223 and the second switch 224, an alternating voltage can be formed on the first side of the transformer 21. After being transferred to the second side of the transformer 21 and stepped up, an alternating high voltage is formed on the second side of the transformer 21.

[0110] Of course, the types of the first switch 223 and the second switch 224 can be switching tubes. The specific types of the switching tubes are not limited in this embodiment, and those skilled in the art can change them according to the actual situation as long as the same technical effects can be achieved.

[0111] Further, in an optional implementation manner, as Figure 2 shown, the voltage generation circuit 22 further includes a capacitor 225. The first end of the capacitor 225 is connected to the first end of the first side, and the second end of the capacitor 225 is connected to the second end of the first side.

[0112] The overall working principle of the dishwasher is as follows:

[0113] First, power is supplied to the dishwasher. After the user puts the tableware into the dishwasher, the user selects different cleaning programs according to the number of tableware placed.

[0114] After the cleaning program is selected, the inner tank of the dishwasher normally fills with water for rinsing. At this time, the disinfectant generator 1 also starts to fill with water. When the liquid level of the disinfectant generator 1 reaches the water level corresponding to the cleaning program, the water inlet stops.

[0115] After that, the ionization component and the power supply component 2 in the disinfectant generator 1 start to work. The ionization component starts to perform corona discharge to produce ozone.

[0116] If the liquid level detection component 17 detects that the actual liquid level is lower than the preset liquid level, the controller 3 controls the power supply component 2 to cut off the power, causing the ionization component to stop operating, and then replenishes water to protect the power supply component 2 from being burned out. When the actual liquid level reaches the preset liquid level, the ionization continues to produce ozone.

[0117] When the total discharge time reaches the set duration, the discharge ends and the ozone preparation process ends.

[0118] The specific working process of the controller 3 is as follows:

[0119] After the whole dishwasher is powered on, it starts to fill water into the cabinet 11 through the water inlet assembly, and the liquid level detection assembly 17 is used to detect the liquid level of the water in the cabinet 11 in real time. Subsequently, the water level is detected, and the processes of supplementing water and discharging water are carried out until the liquid level of the water in the cabinet 11 is within the set value range of the cleaning program.

[0120] Subsequently, the controller 3 controls the power supply assembly 2 to start, and uses the voltage generation circuit 22 to generate an alternating voltage, which is then stepped up through the transformer 21, so that the ionization assembly can perform corona discharge.

[0121] When the discharge time reaches the set duration of the cleaning program, the controller 3 controls the power supply assembly 2 to stop operating.

[0122] After the ozone water is prepared, it is discharged into the inner tank through the drainage assembly to disinfect the tableware.
