Referring to fig. 1, a method for controlling a dishwasher includes steps S100, S200 and S300.

Step S100: acquiring a sterilization device status of a sterilization device in the dishwasher.

Specifically, dish washer includes sterilizing equipment, fan and inner bag subassembly, and sterilizing equipment and fan all connect on the inner bag subassembly, and the inner bag subassembly has the washing tank that holds the tableware, and the fan is located the washing tank outside and is used for carrying the air current to the washing tank in to the stoving tableware, sterilizing equipment locate outside the washing tank and lie in the flow path of air current on, sterilizing equipment is used for disinfecting the air current before the air current flows into the washing tank.

Specifically, still set up the inlet air duct who communicates between outside and washing tank on the inner bag subassembly, sterilizing equipment locates in the inlet air duct and is located the flow path of air current, and fan work, outside air current can flow into to the washing tank in through inlet air duct to the tableware in the washing tank is dried. The sterilizing device is used for sterilizing the air flow in the process that the air flow flows through the air inlet channel.

Alternatively, the sterilization device may be a high temperature sterilization member, a pasteurization member, a plasma generation device, or the like. In an embodiment, the sterilization device is a plasma generation device, and the plasma generation device has the advantages of zero material consumption and high sterilization efficiency, so that the sterilization effect of the dishwasher can be improved while the manufacturing cost of the dishwasher can be reduced. In the following examples, the sterilization apparatus is exemplified as the plasma generation apparatus.

It should be understood that the manner of obtaining the state of the sterilization device is not exclusive, and the state may be obtained by collecting the state through a detection part arranged in the dishwasher and then directly sending the state to the controller; or the user can detect the detection result according to a measuring part arranged in the dishwasher and input the detection result into the controller through a corresponding interaction device. In order to facilitate understanding of the embodiments of the present application, the following explanation is given by taking an example in which the dishwasher is provided with the detection part, and the controller acquires the state of the sterilization apparatus collected by the detection part.

Specifically, the sterilization apparatus state may be any one, two, or three of a light reflectivity of the sterilization apparatus, a stain coverage area of the sterilization apparatus, and a stain thickness of the sterilization apparatus.

Step S200: determining whether a cleaning condition is satisfied based on the sterilizing device status.

Specifically, the cleaning condition may be a judgment condition set according to a general requirement, or may be a judgment condition set according to a special requirement. The cleaning conditions are not unique, and in actual operation, the cleaning conditions can be adjusted according to actual requirements.

For example, the cleaning condition may be less than 20%, or 30%, or 40% in the case where the state of the sterilization apparatus is the light reflectivity of the sterilization apparatus, and may be specifically set as needed. Taking the cleaning condition as less than 30%, that is, when the light reflectivity of the sterilization device measured by the detection element is less than 30%, it indicates that the state of the sterilization device satisfies the cleaning condition, and when the light reflectivity of the sterilization device measured by the detection element is equal to or greater than 30%, it indicates that the state of the sterilization device does not satisfy the cleaning condition.

For another example, the cleaning condition may be more than 2cm in the case where the sterilization apparatus is in a state of a contamination coverage area of the sterilization apparatus ²Or may be greater than 3cm²Or may be greater than 4cm²It can be specifically set as required. Cleaning condition of more than 2cm²For example, that is, when the detection member detects that the area covered by the dirt of the sterilization apparatus is larger than 2cm²If the detection result shows that the state of the sterilization device meets the cleaning condition, the dirty coverage area of the sterilization device measured by the detection part is less than or equal to 2cm²If so, the sterilization device status is not satisfied with the cleaning condition.

Step S300: and when the cleaning condition is determined to be met based on the state of the sterilizing device, controlling the cleaning piece corresponding to the sterilizing device to work so as to improve the cleanliness of the sterilizing device.

Specifically, the higher the cleanliness, the better the sterilization effect of the sterilization apparatus; the lower the cleanliness, the worse the sterilization effect of the sterilization apparatus, and improving the cleanliness of the sterilization apparatus means reducing the cleanliness of the sterilization apparatus so that the sterilization apparatus has a better sterilization effect. When the state of the sterilizing device is determined to meet the cleaning condition, the controller controls the cleaning piece to clean the sterilizing device corresponding to the cleaning piece, so that the cleanliness of the sterilizing device is reduced until the state of the sterilizing device does not meet the cleaning condition; when the state of the sterilizing device does not meet the cleaning condition, the controller controls the cleaning member to be closed.

The control method of the dishwasher comprises the following steps of S100: acquiring a sterilization device state of a sterilization device in the dishwasher, step S200: determining whether a cleaning condition is satisfied based on the sterilizing device status, and step S300: when the cleaning condition is met based on the state determination of the sterilization device, the cleaning piece corresponding to the sterilization device is controlled to work so as to improve the cleanliness of the sterilization device, and the sterilization device can be effectively cleaned, so that the sterilization device has a better sterilization effect. The steps are performed without manual operation, so that the cleaning efficiency is high.

Specifically, the cleaning piece is electrically connected with a controller, and the controller controls the cleaning piece to work or close. Alternatively, the cleaning member may be an ultrasonic vibrator, a water jet or other cleaning means. In one embodiment, the cleaning member is an ultrasonic vibrator. The ultrasonic vibration piece is connected with the sterilization device, and the ultrasonic vibration piece can drive the sterilization device to vibrate by transmitting vibration force to the sterilization device, so that dirt adsorbed on the sterilization device can fall off from the sterilization device, and the sterilization device can be cleaned. Through setting up the cleaning member and being ultrasonic vibration spare, alright clean sterilizing equipment under the condition that need not to use the sanitizer, so, can effectively reduce the manufacturing cost of dish washer, and more practice thrift the environmental protection. The following examples are all described by taking the cleaning member as an ultrasonic vibrator.

Referring to fig. 2, step S100: the method for acquiring the state of the sterilizing device in the dishwasher comprises the steps of acquiring the light reflectivity of a metal electrode of the sterilizing device in the dishwasher, wherein the state of the sterilizing device comprises the light reflectivity;

step S200: when the light reflectivity is smaller than a preset light reflectivity threshold value, determining that the cleaning condition is met;

step S300: and when the cleaning condition is determined to be met based on the light reflection degree, controlling the cleaning piece corresponding to the sterilizing device to work so as to improve the cleanliness of the sterilizing device.

The plasma generating device is provided with a metal electrode, and after high-frequency high-voltage current is introduced to the metal electrode, the metal electrode can generate plasma which can be used for sterilization. Due to long-time use, dirt is easily adsorbed on the metal electrode to cover the metal electrode, and further, the generated plasma cannot effectively contact with air flow, so that the relatively poor sterilization effect of the sterilization device is caused.

The metal electrode has a good light reflection effect, the specific process of testing the light reflection degree of the metal electrode is that the detection piece emits a detection light beam towards the metal electrode, the detection light beam irradiates the metal electrode and then reflects and is received by the detection piece, the detection piece calculates the ratio of the reflected detection light beam to the emitted detection light beam to obtain the light reflection degree of the metal electrode, and then the detection piece sends the light reflection degree to the controller, so that the controller can obtain the light reflection degree of the metal electrode. It can be understood that, if the more detection light beams reflected by the metal electrode, the higher the light reflection degree is, which means that the area of the metal electrode covered by the dirt is smaller, the sterilization device still has a better sterilization effect; if the less the detection light beam reflected by the metal electrode, the smaller the light reflection degree, the larger the area of the metal electrode covered by the dirt is, and the poorer the sterilization effect of the sterilization device is.

The mode of judging the state of the sterilizing device through the light reflection degree of the metal electrode has higher precision, so that the controller can accurately and timely control the cleaning and sterilizing device of the cleaning piece, and the sterilizing device can maintain a better sterilizing effect.

In this embodiment, the dishwasher further includes a power supply, the power supply and the sterilization device are both electrically connected to the controller, and the controller controls the power supply to supply high-frequency high-voltage current to the metal electrode of the sterilization device, or controls the power supply to be disconnected from the metal electrode of the sterilization device.

Referring to fig. 3, the method for controlling a dishwasher further includes the step S400 of: and controlling a spraying piece to spray the sterilizing device when the cleaning piece corresponding to the sterilizing device is controlled to work and/or after the cleaning piece corresponding to the sterilizing device is controlled to work.

The controller can control the spraying part to spray the sterilizing device while controlling the cleaning part corresponding to the sterilizing device to work; or after the controller controls the cleaning piece corresponding to the sterilization device to work, the controller controls the spraying piece to spray the sterilization device; or the controller controls the spraying part to spray the sterilizing device while controlling the cleaning part corresponding to the sterilizing device to work and after the work is finished. The spraying piece can accelerate the dropping speed of dirt from the sterilizing device in the process of spraying the sterilizing device, so that the sterilizing device has higher cleaning effect and cleaning efficiency.

Further, step S400: control and spray a spraying sterilizing equipment includes: and controlling the spraying piece to spray the sterilizing device along at least two different spraying directions.

Optionally, two spraying pieces can be provided, the spraying directions of the spraying pieces are different, and different spraying pieces can spray the sterilization device along different spraying directions; or, two spraying pieces can be adopted, the spraying directions of the spraying pieces are different, and different spraying pieces can asynchronously spray the sterilization device along different spraying directions; the number of the spraying parts can be only one, and the spraying parts of the spraying parts can rotate relative to the sterilization device, so that the spraying parts can spray the sterilization device in different directions at different moments. Therefore, the spraying piece can comprehensively spray the sterilizing device along at least two directions, so that dirt adsorbed on the sterilizing device can be effectively removed, and a better cleaning effect is achieved.

Referring to fig. 4, the method for controlling a dishwasher further includes the step S500: and when the spraying part is controlled to spray the sterilizing device, or after the spraying part is controlled to spray the sterilizing device, controlling the sewage sprayed by the spraying part to be discharged outwards.

Alternatively, the controller can control the spraying member to spray the sterilization device and control the sprayed sewage to be discharged outwards at the same time; or the controller can control the sewage to be discharged outwards after the spraying piece spraying sterilization device is controlled to work. Therefore, the filth dropped from the sterilizing device can be discharged out of the dishwasher following the flow of the water. Thus, the re-contamination of the sterilizing device caused by the accumulation of dirt in the dishwasher can be prevented. Preferably, the controller sprays a spray sterilizing equipment and control the outside discharge of sewage that sprays when and, like this, can prevent to spray that the filth that drops adsorbs again on sterilizing equipment for dish washer has the clean effect of preferred, moreover, can also effectively promote dish washer's clean efficiency.

The dishwasher further comprises a water discharge pipe and a water discharge valve, wherein the inner container assembly is provided with a water discharge port communicated with the air inlet channel, the water discharge pipe is connected to the water discharge port in a matching mode and communicated with the water discharge port to form a water discharge channel, and the water discharge valve is connected to the water discharge pipe in a matching mode. The spraying piece is arranged in the air inlet channel and sprays the sterilizing device, and the sprayed sewage can be discharged to the outside from the water discharging channel.

The controller is electrically connected with the drain valve, and the controller is used for controlling the drain valve to be opened when the spraying part is controlled to spray the sterilizing device or after the spraying part is controlled to spray the sterilizing device, so that the sewage sprayed by the spraying part can be discharged outwards through the drainage channel. And after the sewage is drained, the controller controls the drainage valve to be closed.

Referring to fig. 5, in step S500: after controlling the sewage sprayed by the spraying part to be discharged outwards, the method also comprises the step S600: and controlling the dish washer to cool and dry.

After the sewage sprayed by the spraying part is controlled to be discharged outwards, the sterilizing device has higher cleanliness at the moment and can efficiently sterilize the air flow. At this moment, controller control fan starts, and control sterilizing equipment's metal electrode switches on with the power to make sterilizing equipment can carry out high-efficient the disinfecting to the air current of flowing through inlet air channel, then, the air current after disinfecting flows into to the washing tank in and cools down the stoving to the tableware. And moreover, the sewage sprayed by the spraying part is controlled to be discharged outwards and then is cooled and dried, and the sterilizing device and the air inlet channel can be dried in the process that air flows through the air inlet channel, so that moisture can be prevented from being accumulated in the air inlet channel to breed bacteria.

In one embodiment, step S100: acquiring a sterilization device status of a sterilization device in the dishwasher, including: after the dish washer is dried by hot air and before the dish washer is cooled and dried, the state of a sterilization device of the sterilization device in the dish washer is obtained.

Specifically, the dish-washing machine further comprises a heating element, the heating element is arranged in the air inlet channel and positioned on a flow path of the air flow, and the heating element is used for heating the air flow flowing through the heating element and sterilizing the air flow at high temperature. In the process of carrying out hot air drying, the work of heating member and fan is controlled to the controller, and outside air current flows in the washing tank through inlet air channel, and at the in-process of the heating member of air current flow through, the air current temperature risees and has higher cleanliness factor to can carry out hot air drying to the tableware in the washing tank.

Specifically, after the dishwasher performs hot air drying, the controller controls the sterilizing device state of the sterilizing device in the dishwasher, and determines whether the cleaning condition is satisfied based on the sterilizing device state, when it is determined that the cleaning condition is satisfied based on the state of the sterilizing device, the cleaning member corresponding to the sterilizing device is controlled to operate, so as to improve the cleanliness of the sterilization device, and when the controller controls the cleaning piece corresponding to the sterilization device to work, and/or the controller controls the spraying piece to spray the sterilizing device after controlling the cleaning piece corresponding to the sterilizing device to work, the controller also controls the sewage sprayed by the spraying part to be discharged outwards when the spraying part is controlled to spray the sterilizing device or after the spraying part is controlled to spray the sterilizing device, after controlling the sewage sprayed by the spraying part to be discharged outwards, the controller also controls the dish-washing machine to cool and dry. Because after hot-blast drying, wash the sewage and the filth of tableware in the washing tank and have been arranged to the greatest extent, have higher cleanliness factor in the whole washing tank, acquire sterilizing equipment's sterilizing equipment state this moment, have higher acquisition precision. And the step of obtaining sterilizing state of sterilizing equipment and carrying out clean sterilizing equipment in proper order before cooling and drying can effectively promote the cleanliness factor of the air current of cooling and drying in-process to can further promote the clean effect of dish washer. Moreover, the sterilizing device and the air inlet channel can be dried in the cooling and drying process, so that the bacteria can be prevented from breeding due to the retention of moisture.

In addition, it should be noted that, in some other embodiments, the step of cleaning the sterilization device may also be performed independently, for example, during each start and operation of the dishwasher, the step of cleaning the sterilization device is followed by the step of hot air drying and the step of cooling and drying, and for example, during each start and operation of the dishwasher, the step of cleaning the sterilization device is followed by the step of hot air drying and the step of cooling and drying.

Referring to fig. 8, 9 and 10, the present application further provides a dishwasher 100, wherein the dishwasher 100 is used for washing dishes. The dishwasher 100 includes a tub assembly 10, a blower 20, a sterilizer 30, a cleaning unit 40, and a controller (not shown), the tub assembly 10 has a tub 11 for accommodating dishes, the blower 20 and the sterilizer 30 are coupled to the outside of the tub 11 of the tub assembly 10, and the blower 20 is used to deliver air into the tub 11 to dry the dishes. The sterilizing device 30 is provided on a flow path (a path indicated by an arrow a-an arrow b-an arrow c in fig. 10) of the air flow into the washing tub 11, and is used to sterilize the air flow before the air flow flows into the washing tub 11 to prevent the tableware from being contaminated by microorganisms in the air flow. The cleaning member 40 is coupled to the liner assembly 10 and corresponds to the sterilization device 30, the cleaning member 40 is used for cleaning the sterilization device 30, and only the cleaning member 40 corresponding to the sterilization device 30 can clean the sterilization device 30. The controller is electrically connected to the cleaning member 40, and the controller is configured to acquire a state of the sterilizing device 30, determine whether a cleaning condition is satisfied based on the state of the sterilizing device 30, and control the cleaning member 40 to operate to improve a cleanliness of the sterilizing device 30 when it is determined that the cleaning condition is satisfied based on the state of the sterilizing device 30.

The above-described dishwasher 100 acquires the state of the sterilizing device 30 through the controller, determines whether the cleaning condition is satisfied based on the state of the sterilizing device 30, and controls the operation of the cleaning member 40 corresponding to the sterilizing device 30 to improve the cleanliness of the sterilizing device 30 when it is determined that the cleaning condition is satisfied based on the state of the sterilizing device 30.

For example, the state of the sterilization apparatus 30 is the light reflectivity of the sterilization apparatus 30, and the cleaning condition may be less than 20%, or 30%, or 40%, which may be set as needed. Taking the cleaning condition as less than 30%, that is, when the reflectivity of the sterilization device 30 obtained by the controller is less than 30%, it indicates that the state of the sterilization device 30 satisfies the cleaning condition, and when the reflectivity of the sterilization device 30 obtained by the controller is equal to or greater than 30%, it indicates that the state of the sterilization device 30 does not satisfy the cleaning condition.

For another example, the cleaning condition may be more than 2cm, taking the state of the sterilization apparatus 30 as the dirty coverage area of the sterilization apparatus 30 as an example²Or may be greater than 3cm²Or may be greater than 4cm²It can be specifically set as required.

Specifically, the higher the cleanliness, the better the sterilization effect of the sterilization device 30; the lower the cleanliness, the poorer the sterilization effect of the sterilization device 30, and 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 sterilizing device 30 determines that the cleaning condition is satisfied, the controller controls the cleaning member 40 to clean the sterilizing device 30 corresponding to the cleaning member 40, so that the cleanliness of the sterilizing device 30 is reduced until the state of the sterilizing device 30 does not satisfy the cleaning condition; when the state of the sterilizing device 30 does not satisfy the cleaning condition, the controller controls the cleaning member 40 to be closed.

Alternatively, the sterilization device 30 may be a high temperature sterilization member, a pasteurization member, a plasma generation device, or the like.

By providing the cleaning member 40 as an ultrasonic vibration member, the sterilization device 30 can be cleaned without using a detergent, so that the manufacturing cost of the dishwasher 100 can be effectively reduced, and more economical and environmentally friendly. The following examples are all described by taking the cleaning member 40 as an ultrasonic vibrator.

The dishwasher 100 further includes a detection piece 50, the detection piece 50 is coupled to the inner container assembly 10 and electrically connected to the controller, and the detection piece 50 is configured to detect the state of the sterilization device 30 and transmit the state to the controller. It should be understood that the position of the detection member 50 is not exclusive, as long as the detection member is disposed on the liner assembly 10 and can detect the state of the sterilization device 30. Through setting up the detection piece 50, and the detection piece 50 can be automatically with the sterilizing equipment 30 state of detection send to the controller to be convenient for promote the precision that dish washer 100 detected, and make dish washer 100 more intelligent.
