[0056] See also Figure 1 The control method of a dishwasher includes step S100, step S200 and step S300.

[0057] Step S100: Acquire the sterilization device status of the sterilization device in the dishwasher.

[0058] Specifically, the dishwasher includes a sterilization device, a fan and an inner tank assembly. The sterilization device and the fan are both connected to the inner tank assembly. The inner tank assembly has a cleaning tank for accommodating tableware. The fan is located outside the cleaning tank and is used to transport airflow into the cleaning tank to dry the tableware. The sterilization device is arranged outside the cleaning tank and is located on the flow path of the airflow. The sterilization device is used to sterilize the airflow before it flows into the cleaning tank.

[0059] Specifically, the inner container assembly is provided with an air inlet passage connecting the outside to the washing tank. The sterilization device is located within the air inlet passage and in the airflow path. When the fan is operating, external air flows through the air inlet passage into the washing tank to dry the dishes in the washing tank. The sterilization device is used to sterilize the airflow as it flows through the air inlet passage.

[0060] Alternatively, the sterilization device may be a high-temperature sterilizer, a pasteurizer, a plasma generator, or the like. In one embodiment, the sterilization device is a plasma generator. Plasma generators have the advantages of requiring no consumables and having high sterilization efficiency. This improves the sterilization effectiveness of the dishwasher while also reducing the manufacturing cost. The following embodiments are all described using a plasma generator as an example.

[0061] It should be understood that there is no single way to obtain the sterilization device status. It can be acquired through a detection element installed in the dishwasher and then sent directly to the controller. Alternatively, the user can obtain the status through a measurement element installed in the dishwasher and input it into the controller through a corresponding interactive device. To facilitate understanding of the various embodiments of this application, the following explanation is based on an example in which a dishwasher is equipped with a detection element and the controller obtains the sterilization device status acquired by the detection element.

[0062] Specifically, the state of the sterilization device may be any one, any two, or any three of the reflectivity of the sterilization device, the dirt coverage area of ​​the sterilization device, and the dirt thickness of the sterilization device.

[0063] Step S200: determining whether a cleaning condition is met based on the state of the sterilization device.

[0064] Specifically, the cleaning condition can be a judgment condition set according to general requirements, or a judgment condition set according to special requirements. The cleaning condition is not unique and can be adjusted according to actual needs in actual operation.

[0065] For example, taking the reflectivity of the sterilizer as an example, the cleaning condition can be less than 20%, 30%, or 40%, which can be set as needed. Taking the cleaning condition of less than 30% as an example, that is, when the reflectivity of the sterilizer measured by the detection element is less than 30%, it means that the sterilizer meets the cleaning condition. When the reflectivity of the sterilizer measured by the detection element is equal to or greater than 30%, it means that the sterilizer does not meet the cleaning condition.

[0066] For another example, taking the sterilization device state as the dirty coverage area of ​​the sterilization device, the cleaning condition can be greater than 2cm 2 , or it can be larger than 3cm 2 , or it can be larger than 4cm 2 , which can be set according to the needs. The cleaning condition is greater than 2cm 2 For example, when the dirt coverage area of ​​the sterilization device measured by the test piece is greater than 2cm 2 , it means that the sterilization device meets the cleaning conditions. When the dirty coverage area of ​​the sterilization device measured by the detection part is less than or equal to 2cm 2 , it means that the sterilization device status does not meet the cleaning conditions.

[0067] Step S300: When it is determined based on the state of the sterilization device that a cleaning condition is met, controlling a cleaning component corresponding to the sterilization device to operate to improve the cleanliness of the sterilization device.

[0068] Specifically, the higher the cleanliness, the better the sterilization effect of the sterilization device; the lower the cleanliness, the worse the sterilization effect of the sterilization device. Improving the cleanliness of the sterilization device means reducing the cleanliness of the sterilization device so that the sterilization device has a better sterilization effect. When the sterilization device status is determined to meet the cleaning conditions, the controller controls the cleaning element to clean the sterilization device corresponding to the cleaning element, thereby reducing the cleanliness of the sterilization device, until the sterilization device status does not meet the cleaning conditions. When the sterilization device status does not meet the cleaning conditions, the controller controls the cleaning element to shut down.

[0069] The above-mentioned dishwasher control method includes step S100: obtaining the sterilization device status of the sterilization device in the dishwasher; step S200: determining whether a cleaning condition is met based on the sterilization device status; and step S300: when the cleaning condition is determined to be met based on the sterilization device status, controlling the cleaning element corresponding to the sterilization device to operate to improve the cleanliness of the sterilization device. This method can effectively clean the sterilization device, ensuring that the sterilization device has a good sterilization effect. Since the above-mentioned steps do not require manual operation during execution, they have high cleaning efficiency.

[0070] Specifically, the cleaning part is electrically connected to the controller, and the controller controls the cleaning part to work or shut down. Optionally, the cleaning part can be an ultrasonic vibrator, a water sprayer or other cleaning device. In one embodiment, the cleaning part is an ultrasonic vibrator. The ultrasonic vibrator is connected to the sterilization device. The ultrasonic vibrator can drive the sterilization device to vibrate by transmitting vibration force to the sterilization device, so that the dirt adsorbed on the sterilization device can fall off the sterilization device, thereby achieving the cleaning of the sterilization device. By setting the cleaning part as an ultrasonic vibrator, the sterilization device can be cleaned without using a detergent. In this way, the manufacturing cost of the dishwasher can be effectively reduced, and it is more economical and environmentally friendly. The following embodiments are all described as an ultrasonic vibrator as an example.

[0071] See also Figure 2 Step S100: obtaining the sterilization device status of the sterilization device in the dishwasher, including: obtaining the reflectivity of the metal electrode of the sterilization device in the dishwasher, the sterilization device status including the reflectivity;

[0072] Step S200: When the reflectivity is less than a preset reflectivity threshold, determining that the cleaning condition is met;

[0073] Step S300: When it is determined based on the reflectivity that the cleaning condition is met, controlling the cleaning element corresponding to the sterilization device to operate to improve the cleanliness of the sterilization device.

[0074] Plasma generators have metal electrodes. When a high-frequency, high-voltage current is passed through them, they generate plasma, which can be used for sterilization. However, over time, dirt tends to adhere to and coat the metal electrodes. Consequently, the generated plasma loses effective contact with the airflow, resulting in poor sterilization effectiveness.

[0075] Metal electrodes have a better reflective effect. The specific process of testing the reflectivity of metal electrodes is as follows: the detection component emits a detection beam toward the metal electrode. The detection beam is reflected after irradiating the metal electrode and is received by the detection component. The detection component calculates the ratio of the reflected detection beam to the emitted detection beam to obtain the reflectivity of the metal electrode. The detection component then sends the reflectivity to the controller so that the controller can obtain the reflectivity of the metal electrode. It can be understood that if the metal electrode reflects more detection beams, the reflectivity is higher, which means that the area of ​​the metal electrode covered by dirt is smaller, and the sterilization device still has a better sterilization effect; if the metal electrode reflects fewer detection beams, the reflectivity is smaller, which means that the area of ​​the metal electrode covered by dirt is larger, and the sterilization effect of the sterilization device is poor.

[0076] The method of judging the state of the sterilization device according to the reflectivity of the metal electrode has high accuracy, so that the controller can accurately and timely control the cleaning part to clean the sterilization device, so that the sterilization device can maintain a better sterilization effect.

[0077] In this embodiment, the dishwasher also includes a power supply, and the power supply and the sterilization device are electrically connected to the controller. The controller controls the power supply to pass high-frequency high-voltage current to the metal electrode of the sterilization device, or controls the power supply to disconnect from the metal electrode of the sterilization device.

[0078] See also Figure 3 The control method of the dishwasher also includes step S400: when the cleaning component corresponding to the sterilization device is controlled to work, and / or after the cleaning component corresponding to the sterilization device is controlled to work, controlling the spray component to spray the sterilization device.

[0079] It is understood that the controller can control the spraying element to spray the sterilizing device while controlling the cleaning element corresponding to the sterilizing device to operate; or the controller can control the spraying element to spray the sterilizing device after the cleaning element corresponding to the sterilizing device has completed its operation; or the controller can control the spraying element to spray the sterilizing device both while controlling the cleaning element corresponding to the sterilizing device to operate and after its operation has completed. During the process of spraying the sterilizing device, the spraying element can accelerate the speed at which dirt falls from the sterilizing device, thereby ensuring that the sterilizing device has a higher cleaning effect and cleaning efficiency.

[0080] Furthermore, step S400: controlling the spraying component to spray the sterilization device includes: controlling the spraying component to spray the sterilization device along at least two different spraying directions.

[0081] Alternatively, there may be two spray elements, each with a different spray direction, allowing different spray elements to spray the sterilization device simultaneously in different spray directions. Alternatively, there may be two spray elements, each with a different spray direction, allowing different spray elements to spray the sterilization device asynchronously in different spray directions. Alternatively, there may be only one spray element, and the spray portion of the spray element may be rotatable relative to the sterilization device, allowing the spray portion to spray the sterilization device in different directions at different times. Thus, the spray element can fully spray the sterilization device in at least two directions, effectively removing dirt adsorbed on the sterilization device and achieving a better cleaning effect.

[0082] See also Figure 4 The control method of the dishwasher further includes step S500: when the controlled spray part sprays the sterilization device, or after the controlled spray part sprays the sterilization device, controlling the sewage sprayed by the spray part to be discharged outward.

[0083] Optionally, the controller can simultaneously control the spraying element to spray the sterilizing device and discharge the sprayed sewage; alternatively, the controller can control the sewage discharge after the spraying element has finished spraying the sterilizing device. Therefore, dirt that falls from the sterilizing device can be discharged from the dishwasher along with the flow of water. This prevents dirt from accumulating inside the dishwasher and causing re-contamination of the sterilizing device. Preferably, the controller simultaneously controls the spraying element to spray the sterilizing device and discharge the sprayed sewage. This prevents dirt that falls from the spray from being re-adsorbed onto the sterilizing device, allowing the dishwasher to achieve a better cleaning effect and effectively improving the cleaning efficiency of the dishwasher.

[0084] As can be understood, the dishwasher also includes a drain pipe and a drain valve. The inner tank assembly is provided with a drain port connected to the air inlet channel. The drain pipe is connected to the drain port and communicates with the drain port to form a drain channel. The drain valve is connected to the drain pipe. A spray element is located within the air inlet channel and sprays the sterilizing device. The resulting wastewater can be discharged to the outside through the drain channel.

[0085] The controller is electrically connected to the drain valve. The controller is configured to control the drain valve to open when or after the spray element sprays the sterilization device, allowing wastewater sprayed by the spray element to be discharged through the drainage channel. When the wastewater is completely discharged, the controller controls the drain valve to close.

[0086] See also Figure 5After step S500: controlling the sewage after spraying by the spraying part to be discharged outward, the method further includes step S600: controlling the dishwasher to cool down and dry.

[0087] After the wastewater from the spraying element is controlled to be discharged, the sterilization device now has a high degree of cleanliness and is effectively sterilizing the airflow. At this point, the controller activates the fan and connects the metal electrodes of the sterilization device to a power source, enabling the sterilization device to effectively sterilize the airflow passing through the air inlet channel. The sterilized airflow then flows into the washing tank, cooling and drying the dishes. Furthermore, after the wastewater from the spraying element is controlled to be discharged, the airflow through the air inlet channel also dries the sterilization device and the air inlet channel, thereby preventing moisture from accumulating in the air inlet channel and breeding bacteria.

[0088] In one embodiment, step S100: obtaining the sterilization device status of the sterilization device in the dishwasher includes: obtaining the sterilization device status of the sterilization device in the dishwasher after the dishwasher performs hot air drying and before cooling and drying.

[0089] Specifically, the dishwasher also includes a heater, located within the air inlet duct and along the airflow path. This heater heats the airflow passing through it and sterilizes it at high temperatures. During hot air drying, a controller controls the heater and fan, drawing external air through the air inlet duct into the washing tank. As the air flows through the heater, its temperature rises, achieving a higher degree of cleanliness, thereby drying the dishes within the washing tank.

[0090] Specifically, after the dishwasher performs hot air drying, the controller controls the sterilization device status of the sterilization device in the dishwasher and determines whether the cleaning conditions are met based on the sterilization device status. When it is determined that the cleaning conditions are met based on the sterilization device status, the controller controls the cleaning component corresponding to the sterilization device to operate to improve the cleanliness of the sterilization device. While the controller controls the cleaning component corresponding to the sterilization device to operate, and / or after the controller controls the cleaning component corresponding to the sterilization device to operate, the controller controls the spray component to spray the sterilization device. While controlling the spray component to spray the sterilization device, or after controlling the spray component to spray the sterilization device, the controller also controls the wastewater sprayed by the spray component to be discharged. After controlling the wastewater sprayed by the spray component to be discharged, the controller also controls the dishwasher to perform cooling and drying. Since the wastewater and dirt from washing dishes in the washing tank have been drained after hot air drying, the entire washing tank has a high degree of cleanliness. At this time, the sterilization device status of the sterilization device is obtained with high acquisition accuracy. Acquiring the sterilization status of the sterilization device and sequentially performing the sterilization device cleaning steps before cooling and drying can effectively improve the cleanliness of the airflow during the cooling and drying process, thereby further enhancing the cleaning effect of the dishwasher. Furthermore, the sterilization device and air inlet duct can be dried during the cooling and drying process, thereby preventing moisture retention and bacterial growth.

[0091] In addition, it should be noted that in some other embodiments, the steps of cleaning and sterilizing the device can also be performed independently. For example, each time the dishwasher is started and works, the steps of hot air drying and cooling drying are performed in sequence after the step of cleaning and sterilizing the device. For another example, each time the dishwasher is started and works, the steps of hot air drying and cooling drying are performed in sequence before the step of cleaning and sterilizing the device.

[0092] Next, the control method of the entire dishwasher is described in detail.

[0093] See also Figure 6 The dishwasher also includes step S700: controlling the adding component to add detergent into the cleaning tank and controlling the cleaning component to clean the tableware in the cleaning tank, and step S800: the controller controls the heating component and the fan to work and dry the tableware with hot air.

[0094] After the controller is activated, it first controls the execution of step S700: controlling the adding component to add detergent to the cleaning tank and controlling the cleaning component to clean the dishes in the cleaning tank; after step S700 ends, the controller executes step S800: controlling the heating component and the fan to operate, drying the dishes with hot air. After step S800 ends, the controller executes step S100: obtaining the sterilization device status of the sterilization device in the dishwasher; after step S100 ends, the controller executes step S200: determining whether the cleaning condition is met based on the sterilization device status; after step S200 ends, if the sterilization device status does not meet the cleaning condition, the controller executes step S600: controlling the dishwasher to cool and dry the dishes; after step S600 ends, the entire dishwasher control method ends. After step S200 is completed, and when the state of the sterilization device meets the cleaning conditions, the controller executes step S300: when it is determined based on the reflectivity that the cleaning conditions are met, the controller controls the cleaning component corresponding to the sterilization device to operate to improve the cleanliness of the sterilization device; during step S300 and / or after step S300 is completed, the controller may also execute step S400: control the spray component to spray the sterilization device. During and / or after executing step S400, the controller also executes step S500: controls the sewage after the spray component is sprayed to be discharged. After step S500 is completed, the controller executes step S600: controls the dishwasher to cool and dry; after step S600 is completed, the entire dishwasher control method is completed. Of course, in some other embodiments, the execution process of the control method of the dishwasher may also be: the controller sequentially executes step S700 → step S800 → step S600 → step S100 → step S200 → step S300 → step S400 → step S500.

[0095] See also Figure 7 The present application also provides a control device for a dishwasher, which includes an acquisition module 200 and a judgment and control module 300.

[0096] The acquisition module 200 acquires the sterilization device status of the sterilization device in the dishwasher.

[0097] Specifically, the dishwasher includes a sterilization device, a fan and an inner tank assembly. The sterilization device and the fan are both connected to the inner tank assembly. The inner tank assembly has a cleaning tank for accommodating tableware. The fan is located outside the cleaning tank and is used to transport airflow into the cleaning tank to dry the tableware. The sterilization device is arranged outside the cleaning tank and is located on the flow path of the airflow. The sterilization device is used to sterilize the airflow before it flows into the cleaning tank.

[0098] Specifically, the inner container assembly is provided with an air inlet passage connecting the outside to the washing tank. The sterilization device is located within the air inlet passage and in the airflow path. When the fan is operating, the external airflow can flow into the washing tank through the air inlet passage to clean the dishes in the washing tank. The sterilization device is used to sterilize the airflow as it flows through the air inlet passage.

[0099] Alternatively, the sterilization device may be a high-temperature sterilizer, a pasteurizer, a plasma generator, or the like. Specifically, in this embodiment, the sterilization device is a plasma generator. Plasma generators have the advantages of requiring no consumables and having high sterilization efficiency. This improves the sterilization effectiveness of the dishwasher while also reducing its manufacturing cost. The following embodiments are described using a plasma generator as an example.

[0100] It should be understood that there is no single way to obtain the sterilization device status. It can be acquired through a detection element installed in the dishwasher and then sent directly to the controller. Alternatively, the user can obtain the status through a measurement element installed in the dishwasher and input it into the controller through a corresponding interactive device. To facilitate understanding of the various embodiments of this application, the following explanation is based on an example in which a dishwasher is equipped with a detection element and the controller obtains the sterilization device status acquired by the detection element.

[0101] Specifically, the state of the sterilization device may be any one, any two, or any three of the reflectivity of the sterilization device, the dirt coverage area of ​​the sterilization device, and the dirt thickness of the sterilization device.

[0102] The judgment and control module 300 is used to determine whether the cleaning conditions are met based on the state of the sterilization device. When it is determined based on the state of the sterilization device that the cleaning conditions are met, the cleaning component corresponding to the sterilization device is controlled to work to improve the cleanliness of the sterilization device.

[0103] Specifically, the cleaning condition can be a judgment condition set according to general requirements, or a judgment condition set according to special requirements. The cleaning condition is not unique and can be adjusted according to actual needs in actual operation.

[0104] For example, taking the reflectivity of the sterilizer as an example, the cleaning condition can be less than 20%, 30%, or 40%, which can be set as needed. Taking the cleaning condition of less than 30% as an example, that is, when the reflectivity of the sterilizer measured by the detection element is less than 30%, it means that the sterilizer meets the cleaning condition. When the reflectivity of the sterilizer measured by the detection element is equal to or greater than 30%, it means that the sterilizer does not meet the cleaning condition.

[0105] For another example, taking the sterilization device state as the dirty coverage area of ​​the sterilization device, the cleaning condition can be greater than 2cm 2 , or it can be larger than 3cm 2 , or it can be larger than 4cm 2 , which can be set according to the needs. The cleaning condition is greater than 2cm 2 For example, when the dirt coverage area of ​​the sterilization device measured by the test piece is greater than 2cm 2 , it means that the sterilization device meets the cleaning conditions. When the dirty coverage area of ​​the sterilization device measured by the detection part is less than or equal to 2cm 2 , it means that the sterilization device status does not meet the cleaning conditions.

[0106] Specifically, the higher the cleanliness, the better the sterilization effect of the sterilization device; the lower the cleanliness, the worse the sterilization effect of the sterilization device. Improving the cleanliness of the sterilization device means reducing the cleanliness of the sterilization device so that the sterilization device has a better sterilization effect. When the sterilization device status is determined to meet the cleaning conditions, the controller controls the cleaning element to clean the sterilization device corresponding to the cleaning element, thereby reducing the cleanliness of the sterilization device, until the sterilization device status does not meet the cleaning conditions. When the sterilization device status does not meet the cleaning conditions, the controller controls the cleaning element to shut down.

[0107] The control device obtains the sterilization device status of the sterilization device in the dishwasher via the acquisition module 200, and determines whether a cleaning condition is met based on the sterilization device status via the judgment and control module 300. When the cleaning condition is determined to be met based on the sterilization device status, the control device controls the operation of the cleaning element corresponding to the sterilization device to improve the cleanliness of the sterilization device, thereby effectively cleaning the sterilization device and achieving a good sterilization effect. Since the above steps do not require manual operation during execution, they have high cleaning efficiency.

[0108] Specifically, the cleaning part is electrically connected to the controller, and the controller controls the cleaning part to work or shut down. Optionally, the cleaning part can be an ultrasonic vibrator, a water sprayer or other cleaning device. In one embodiment, the cleaning part is an ultrasonic vibrator. The ultrasonic vibrator is connected to the sterilization device. The ultrasonic vibrator can drive the sterilization device to vibrate by transmitting vibration force to the sterilization device, so that the dirt adsorbed on the sterilization device can fall off the sterilization device, thereby achieving the cleaning of the sterilization device. By setting the cleaning part as an ultrasonic vibrator, the sterilization device can be cleaned without using a detergent. In this way, the manufacturing cost of the dishwasher can be effectively reduced, and it is more economical and environmentally friendly. The following embodiments are all described as an ultrasonic vibrator as an example.

[0109] In one embodiment, the acquisition module 200 is configured to obtain the reflectivity of the metal electrode of the sterilization device in the dishwasher, where the sterilization device status includes the reflectivity. The determination and control module 300 is configured to determine that the cleaning condition is satisfied when the reflectivity is less than a preset reflectivity threshold. When the cleaning condition is determined to be satisfied based on the reflectivity, the determination and control module 300 controls the operation of the cleaning element corresponding to the sterilization device to improve the cleanliness of the sterilization device. The specific operations are similar to those of the above method and are not further described here.

[0110] In one embodiment, the determination and control module 300 is configured to control the spraying element to spray the sterilization device while the cleaning element corresponding to the sterilization device is operating and / or after the cleaning element corresponding to the sterilization device has completed its operation. The specific operation is similar to that of the above method and will not be repeated here.

[0111] In one embodiment, the judgment and control module 300 is used to control the spraying element to spray the sterilization device along at least two different spraying directions. The specific operation is similar to the above method and will not be repeated here.

[0112] In one embodiment, the judgment and control module 300 is used to control the wastewater sprayed by the spraying member to be discharged when the spraying member sprays the sterilization device, or after the spraying member sprays the sterilization device. The specific operation is similar to the above method and will not be repeated here.

[0113] In one embodiment, the judgment and control module 300 is used to control the dishwasher to cool and dry the wastewater after controlling the wastewater to be discharged after the wastewater is sprayed by the spraying element. The specific operation is similar to the above method and will not be repeated here.

[0114] In one embodiment, the judgment and control module 300 is used to obtain the sterilization device status of the sterilization device in the dishwasher after the dishwasher performs hot air drying and before cooling drying. The specific operation is similar to the above method and will not be repeated here.

[0115] In one embodiment, the judgment and control module 300 is used to control the adding component to add detergent into the cleaning tank and control the cleaning component to clean the dishes in the cleaning tank. The specific operations are similar to the above method and will not be repeated here.

[0116] In one embodiment, the judgment and control module 300 is used to control the operation of the heating element and the fan to dry the dishes with hot air. The specific operation is similar to the above method and will not be repeated here.

[0117] Please also refer to Figure 8 、 Figure 9 and Figure 10The present application also provides a dishwasher 100, which is used to wash dishes. The dishwasher 100 includes an inner tank assembly 10, a fan 20, a sterilizing device 30, a cleaning member 40, and a controller (not shown). The inner tank assembly 10 has a cleaning tank 11 for accommodating dishes. The fan 20 and the sterilizing device 30 are connected to the outside of the cleaning tank 11 of the inner tank assembly 10. The fan 20 is used to deliver airflow into the cleaning tank 11 to dry the dishes. The sterilizing device 30 is arranged in the flow path ( Figure 10 The controller is electrically connected to the cleaning component 40. The controller is used to obtain the status of the sterilizing device 30 of the sterilizing device 30, and to determine whether the cleaning conditions are met based on the status of the sterilizing device 30. When it is determined that the cleaning conditions are met based on the status of the sterilizing device 30, the cleaning component 40 is controlled to work to improve the cleanliness of the sterilizing device 30.

[0118] The dishwasher 100, through a controller, obtains the status of the sterilization device 30 and determines whether cleaning conditions are met based on the status. If the cleaning conditions are determined to be met based on the status of the sterilization device 30, the controller controls the cleaning element 40 corresponding to the sterilization device 30 to operate, thereby improving the cleanliness of the sterilization device 30. This effectively cleans the sterilization device 30, ensuring a good sterilization effect. Furthermore, since no human intervention is required during the sterilization device 30 cleaning process, the dishwasher 100 achieves high cleaning efficiency.

[0119] Please refer to 9 again. Specifically, the state of the sterilization device 30 can be any one, any two, or any three of the reflectivity of the sterilization device 30, the dirt coverage area of ​​the sterilization device 30, and the dirt thickness of the sterilization device 30.

[0120] Specifically, the cleaning condition can be a judgment condition set according to general requirements, or a judgment condition set according to special requirements. The cleaning condition is not unique and can be adjusted according to actual needs in actual operation.

[0121] For example, taking the reflectivity of the sterilizer 30 as an example, the cleaning condition can be less than 20%, 30%, or 40%, which can be set as needed. Taking the cleaning condition of less than 30% as an example, when the reflectivity of the sterilizer 30 obtained by the controller is less than 30%, it means that the sterilizer 30 meets the cleaning condition. When the reflectivity of the sterilizer 30 obtained by the controller is equal to or greater than 30%, it means that the sterilizer 30 does not meet the cleaning condition.

[0122] For another example, taking the state of the sterilizing device 30 as the dirty coverage area of ​​the sterilizing device 30, the cleaning condition may be greater than 2 cm 2 , or it can be larger than 3cm 2 , or it can be larger than 4cm 2 , which can be set according to the needs. The cleaning condition is greater than 2cm 2 For example, when the dirt coverage area of ​​the sterilization device 30 measured by the detection element 50 is greater than 2 cm 2 , it means that the sterilization device 30 meets the cleaning condition. When the dirt coverage area of ​​the sterilization device 30 measured by the detection element 50 is less than or equal to 2cm 2 , it means that the state of the sterilization device 30 does not meet the cleaning conditions.

[0123] Specifically, the higher the cleanliness, the better the sterilization effect of the sterilization device 30; the lower the cleanliness, the worse the sterilization effect of the sterilization device 30. Improving the cleanliness of the sterilization device 30 means reducing the cleanliness of the sterilization device 30 so that the sterilization device 30 has a better sterilization effect. When the state of the sterilization device 30 is determined to meet the cleaning conditions, the controller controls the cleaning element 40 to clean the sterilization device 30 corresponding to the cleaning element 40, thereby reducing the cleanliness of the sterilization device 30 until the state of the sterilization device 30 no longer meets the cleaning conditions. When the state of the sterilization device 30 no longer meets the cleaning conditions, the controller controls the cleaning element 40 to shut down.

[0124] Alternatively, the sterilization device 30 may be a high-temperature sterilizer, a pasteurizer, a plasma generator, or the like. In one embodiment, the sterilization device 30 is a plasma generator. Plasma generators have the advantages of requiring no consumables and having high sterilization efficiency. This improves the sterilization effectiveness of the dishwasher 100 while also reducing the manufacturing cost of the dishwasher 100. The following embodiments are described using the plasma generator as an example.

[0125] Specifically, the cleaning component 40 is electrically connected to the controller, and the controller controls the operation or shutdown of the cleaning component 40. Optionally, the cleaning component 40 can be an ultrasonic vibrator, a water sprayer or other cleaning device. In one embodiment, the cleaning component 40 is an ultrasonic vibrator. The ultrasonic vibrator is connected to the sterilization device 30. The ultrasonic vibrator can drive the sterilization device 30 to vibrate by transmitting vibration force to the sterilization device 30, so that the dirt adsorbed on the sterilization device 30 can fall off the sterilization device 30, thereby achieving the cleaning of the sterilization device 30. By setting the cleaning component 40 as an ultrasonic vibrator, the sterilization device 30 can be cleaned without using a detergent. In this way, the manufacturing cost of the dishwasher 100 can be effectively reduced, and it is more economical and environmentally friendly. The following embodiments are all described as an ultrasonic vibrator.

[0126] The dishwasher 100 also includes a detection member 50, which is attached to the inner tank assembly 10 and electrically connected to the controller. The detection member 50 is configured to detect the status of the sterilization device 30 of the sterilization device 30 and send it to the controller. It should be understood that the location of the detection member 50 is not unique, as long as it is set on the inner tank assembly 10 and can detect the status of the sterilization device 30. By setting the detection member 50 and the detection member 50 being able to automatically send the detected status of the sterilization device 30 to the controller, the accuracy of the detection of the dishwasher 100 is improved and the dishwasher 100 is made more intelligent. The inner tank assembly 10 is also provided with an air inlet channel 14 connecting the outside and the cleaning tank 11. The fan 20 is used to drive the external air flow into the air inlet channel 14. When the fan 20 is working, the external air flow can flow into the cleaning tank 11 through the air inlet channel 14 to dry the tableware in the cleaning tank 11. The sterilization device 30 is disposed in the air inlet channel 14 and is located on the flow path of the air flow. The sterilization device 30 is used to sterilize the air flow as it flows through the air inlet channel 14. At least the detection end of the detection member 50 extends into the air inlet channel 14 to facilitate the detection member 50 to perform detection.

[0127] Please refer to 10. Specifically, the inner tank assembly 10 includes an inner tank 12 and an air inlet shell 13 connected to each other. The inner tank 12 has a cleaning tank 11, and an air inlet (not shown) connected to the cleaning tank 11 is opened on the inner tank 12. The air inlet shell 13 is connected to the air inlet, and the air inlet shell 13 has an air inlet channel 14 and an input port 16. The outside, the input port 16, the air inlet channel 14, the air inlet and the cleaning tank 11 are connected in sequence. Under the action of the fan 20, the external airflow can flow into the cleaning tank 11 through the input port 16, the air inlet channel 14 and the air inlet in sequence to dry the tableware in the cleaning tank 11. The fan 20, the detection component 50 and the sterilization device 30 are all connected to the air inlet housing 13. Specifically, the fan 20, the detection component 50 and the sterilization device 30 are all accommodated in the air inlet channel 14. The air inlet housing 13 can protect the fan 20, the detection component 50 and the sterilization device 30 to prevent the fan 20, the detection component 50 and the sterilization device 30 from being damaged.

[0128] Specifically, the sterilization device 30 is a plasma generating device, and the detection component 50 is configured to detect the reflectivity of the metal electrode of the sterilization device 30 and send it to the controller. When the reflectivity is less than a preset reflectivity threshold, the controller controls the cleaning component 40 to operate.

[0129] The plasma generator has metal electrodes. When a high-frequency, high-voltage current is passed through the metal electrodes, they generate plasma, which can be used for sterilization. However, over time, dirt tends to adhere to and coat the metal electrodes. Consequently, the generated plasma cannot effectively interact with the airflow, resulting in a poor sterilization effect of the sterilization device 30.

[0130] The metal electrode has a better reflective effect. The specific process of testing the reflectivity of the metal electrode is as follows: the detection component 50 emits a detection beam toward the metal electrode. The detection beam is reflected after irradiating the metal electrode and is received by the detection component 50. The detection component 50 calculates the ratio of the reflected detection beam to the emitted detection beam to obtain the reflectivity of the metal electrode. The detection component 50 then sends the reflectivity to the controller so that the controller can obtain the reflectivity of the metal electrode. It can be understood that if the metal electrode reflects more detection beams, the reflectivity is higher, which means that the area of ​​the metal electrode covered by dirt is smaller, and the sterilization device 30 still has a better sterilization effect; if the metal electrode reflects fewer detection beams, the reflectivity is smaller, which means that the area of ​​the metal electrode covered by dirt is larger, and the sterilization effect of the sterilization device 30 is poor.

[0131] Determining the status of the sterilizing device 30 based on the reflectivity of the metal electrode provides high accuracy, enabling the controller to accurately and timely control the cleaning element 40 to clean the sterilizing device 30, thereby maintaining an optimal sterilization effect. In this embodiment, the dishwasher 100 also includes a power supply. The power supply and the sterilizing device 30 are both electrically connected to the controller. The controller controls the power supply to supply a high-frequency, high-voltage current to the metal electrode of the sterilizing device 30, or to disconnect the power supply from the metal electrode of the sterilizing device 30.

[0132] The dishwasher 100 also includes a spraying member 60, which is connected to the inner tank assembly 10 and electrically connected to the controller. The controller is used to control the spraying member 60 to spray the sterilization device 30 when controlling the cleaning member 40 to work and / or after controlling the cleaning member 40 to work.

[0133] It is understood that the controller can control the spraying member 60 to spray the sterilizing device 30 while controlling the operation of the cleaning member 40 corresponding to the sterilizing device 30; alternatively, the controller can control the spraying member 60 to spray the sterilizing device 30 after the operation of the cleaning member 40 corresponding to the sterilizing device 30 is completed; alternatively, the controller can control the spraying member 60 to spray the sterilizing device 30 both while controlling the operation of the cleaning member 40 corresponding to the sterilizing device 30 and after the operation is completed. In the process of spraying the sterilizing device 30, the spraying member 60 can accelerate the speed at which dirt falls from the sterilizing device 30, thereby ensuring that the sterilizing device 30 has a higher cleaning effect and cleaning efficiency.

[0134] Specifically, a spray element 60 is disposed within the air inlet duct 14 and sprays the sterilization device 30. Optionally, there may be one or at least two spray elements 60. If there are at least two, the at least two spray elements 60 may be spaced apart circumferentially around the sterilization device 30. Preferably, there are at least two spray elements 60, and the at least two spray elements 60 may be spaced apart circumferentially around the sterilization device 30, with each spray element 60 spraying the sterilization device 30 in a different direction. By providing at least two spray elements 60, each spray element 60 can fully spray the sterilization device 30 from different directions and positions, thereby achieving a better cleaning effect on the sterilization device 30.

[0135] Furthermore, each spray element 60 includes a drive unit (not shown) and a spraying portion drivingly connected to the drive unit (not shown). A controller is electrically connected to the drive unit and is configured to control the drive unit to drive the spraying portion to spray the sterilization device 30 in at least two different spraying directions. In other words, the drive unit can control the rotation of the spraying portion so that the spraying portion sprays the sterilization device 30 in different directions. This effectively removes dirt adsorbed on the sterilization device 30, resulting in a better cleaning effect.

[0136] The spray component 60 also includes a spray switch (not shown in the figure). The spray switch is connected to the spray part and is electrically connected to the controller. The controller controls the spray switch to open to control the spray part to spray water to the sterilization device 30. The controller controls the spray switch to close to control the spray part to stop spraying water to the sterilization device 30.

[0137] It can be understood that the controller controls the spray part 60 to spray the sterilization device 30, which can be understood as the controller controlling the spray switch to open so that the spray part can spray water to the sterilization device 30; or, it can also be understood as the controller controlling the spray switch to open, and controlling the driving part to drive the spray part toward the sterilization device 30 and spray water to the sterilization device 30.

[0138] In one embodiment, the inner container assembly 10 is provided with a drain port 15 communicating with the air inlet passage 14. The dishwasher 100 further includes a drain pipe 70. The inner container assembly 10 is provided with the drain port 15 communicating with the air inlet passage 14. Specifically, the air inlet housing 13 is provided with the drain port 15 communicating with the air inlet passage 14. The drain pipe 70 is coupled to the drain port 15 and is in fluid communication with the drain port 15, thereby forming a drainage passage for the sprayed wastewater to be discharged from the air inlet passage 14. The provision of the drain pipe 70 guides the sprayed wastewater in the air inlet passage 14 to be discharged externally, thereby preventing the wastewater from accumulating in the air inlet passage 14 and reducing the cleanliness of the sterilization device 30.

[0139] Specifically, the dishwasher 100 is further provided with a drain channel, with the washing tank 11 and the drainage channel both communicating with the drain channel. The wastewater generated after washing dishes in the washing tank 11 and the wastewater sprayed in the air inlet channel 14 are both channeled into the drain channel and then flow out. Optionally, the drain channel can be provided on the inner liner 12 of the inner liner assembly 10, on the air inlet housing 13, or on other components of the dishwasher 100.

[0140] The dishwasher 100 also includes a drain valve, which is connected to the drain pipe 70 and electrically connected to the controller; the controller controls the drain valve to open and close the drainage channel. Specifically, the controller is used to control the drain valve to open while controlling the spray part 60 to spray the sterilization device 30, or after controlling the spray part 60 to spray the sterilization device 30, so that the sewage sprayed by the spray part 60 can be discharged outward through the drainage channel. When the sewage is drained, the controller controls the drain valve to close. By setting the drain valve to be electrically connected to the controller, the drainage channel can be opened or closed as needed to meet the diverse needs of users. Specifically, for example, when the dishwasher 100 is washing dishes, the drain valve can be controlled to close to prevent the water in the washing tank 11 from leaking through the air inlet channel 14 and the drainage channel.

[0141] Dishwasher 100 also includes a heater 90. Heater 90 is coupled to inner container assembly 10 and located in the airflow path leading to washing tank 11. Heater 90 is configured to heat the airflow passing therethrough. Specifically, heater 90 is coupled to air inlet passage 14 of air inlet housing 13 and is configured to heat and sterilize the airflow passing therethrough.

[0142] It is understood that if both the heater 90 and the fan 20 are activated, the airflow flowing into the washing tank 11 has a higher temperature and cleanliness, thereby hot-air drying the dishes in the washing tank 11 and preventing contamination of the dishes. If the heater 90 is off and the fan 20 is activated, the airflow flowing into the washing tank 11 has a lower temperature, thereby cooling and drying the dishes. It is worth mentioning that since the heater 90 heats and sterilizes the airflow when activated, the sterilization device 30 can be turned off during the hot-air drying process of the dishwasher 100. However, during the cooling and drying process of the dishwasher 100, to ensure the high cleanliness of the airflow flowing into the washing tank 11, the sterilization device 30 should be activated to sterilize the airflow.

[0143] Next, the entire working process of the dishwasher 100 will be described in detail.

[0144] The dishwasher 100 also includes an addition unit and a cleaning unit. The addition unit stores detergent, and the cleaning unit is located in the cleaning tank 11 and is used to clean dishes. The entire operating process of the dishwasher 100 is as follows: a controller controls the addition unit to add detergent to the cleaning tank 11 and controls the cleaning unit to clean the dishes. After the cleaning unit completes its operation, the controller activates the heating unit 90 and the fan 20. External air flows into the cleaning tank 11 through the air inlet duct 14 and the air inlet, drying the dishes in the cleaning tank 11 with hot air. After the hot air drying is complete, the detection unit 50 detects the status of the sterilization device 30 and transmits the information to the controller. Based on the status of the sterilization device 30, the controller determines whether the cleaning conditions are met. If the status of the sterilization device 30 does not meet the cleaning conditions, the controller activates the fan 20 and controls electrical conduction between the power supply and the sterilization device 30, thereby cooling and drying the dishes while preventing contamination. After the cooling and drying process is complete, the entire operating process of the dishwasher 100 is complete. When the sterilization device 30 meets the cleaning requirements, the controller activates the cleaning element 40. Furthermore, while and / or after the cleaning element 40 is activated, the controller activates the spray element 60 to spray the sterilization device 30. Furthermore, during or after the spraying process, the controller also activates the drain valve to drain the wastewater. Furthermore, the controller activates the fan 20 and maintains electrical continuity between the power supply and the sterilization device 30, cooling and drying the dishes while preventing contamination. Once the cooling and drying process is complete, the entire dishwasher 100 operation process is complete.

[0145] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0146] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
