Specifically, since the objects to be washed are easily stacked in the water tank, the objects to be washed are placed at different heights in the washing areaIn order to ensure the cleaning effect and save water, the water inlet level required for cleaning is different. The inner wall of the cleaning area of the water tank is provided with a preset reference line, the highest position of an object to be cleaned in the cleaning area is determined according to the first image, the placing height of the object to be cleaned is determined through the distance between the highest position and the preset reference line, and the calculating formula of the placing height h of the object to be cleaned is as follows: h is h ₀ + Δ h; wherein h is ₀ In order to preset the height of the datum line, Δ h is the distance between the highest position of the object to be cleaned and the preset datum line.

And S2, determining a cleaning and purifying mode according to the category of the object to be cleaned, and determining the preset water inlet level corresponding to the object to be cleaned according to the placing height of the object to be cleaned.

In a specific embodiment, the determining the cleaning and purifying mode according to the category of the object to be cleaned in step S2 specifically includes:

In particular, the categories of the object to be washed include, but are not limited to, fruits, vegetables, seafood, and meat. The cleaning and purifying modes corresponding to the objects to be cleaned in different categories are different, so that a first relation between the objects to be cleaned in different categories and the different cleaning and purifying modes needs to be established, and the corresponding cleaning and purifying modes are determined by adopting the first relation according to the categories of the objects to be cleaned determined by the first image. The cleaning and cleaning mode includes, but is not limited to, a cleaning mode and/or a rinsing mode, and for example, when the category of the object to be cleaned is fruit, the cleaning mode can be selected to be entered first and then the rinsing mode is entered. In other embodiments, when the object to be cleaned is in other different categories, other different cleaning and purifying modes can be adopted.

In one embodiment, the object to be cleaned is a vegetable (green leaf), and the corresponding cleaning and purifying mode is to turn on the water catalyst module, the ultrasonic module and the air pump, wherein the ultrasonic module is turned on intermittently. Because vegetables surface residual has earth and pesticide, consequently need open ultrasonic wave module and air pump simultaneously, wash vegetables surperficial earth, open water catalyst module and can get rid of harmful substance such as vegetables surperficial residual pesticide, reach the powerful while of getting rid of vegetables surface mud dirt and disinfect and remove the pesticide residue, the ultrasonic wave module is interrupted to open and to be caused the damage to vegetables in can avoiding the cleaning process.

In one embodiment, the object to be cleaned is poultry meat, and the corresponding cleaning and purifying modes are a water catalyst module and an air pump, wherein the ultrasonic module is not started. Because the poultry meat is easy to remain harmful substances such as bacteria and a small amount of dirt, the water catalyst and the air pump can be started simultaneously, the dirt on the surface of the poultry meat is cleaned while the poultry meat is sterilized and disinfected, and the nutrition loss of the poultry meat is not influenced.

In one embodiment, the object to be cleaned is seafood, and the corresponding cleaning and purifying mode is to turn on the water catalyst module, the ultrasonic module and the air pump. Some harmful chemical substances and dirt can be possibly remained in the seafood, and the dirt is difficult to clean, so that the water catalyst module, the ultrasonic module and the air pump can be started simultaneously, the harmful chemical substances can be removed, the dirt can be strongly washed, and the sanitation and safety of the seafood in the eating process are ensured. Therefore, different cleaning and purifying modes can be correspondingly obtained according to different types of the objects to be cleaned, and the cleaning and purifying device is more targeted.

Specifically, predetermine the height of placing of intaking water level more than or equal to waiting to wash the thing, as preferred, predetermine the water level of intaking and equal to the height of placing of waiting to wash the thing, can play the effect of using water wisely, do not influence the cleaning performance again. In a specific embodiment, the preset water inlet level can be determined according to the comparison between the placement height of the object to be cleaned and the threshold range. Suppose the degree of depth of basin is 200mm, predetermines the water level of intaking and can set up to 5 grades, then the corresponding water level of intaking of predetermineeing can be divided into following 5 according to waiting to wash the placing height of thing:

if the placing height of the object to be cleaned is lower than 80mm, the preset water inlet level is 80 mm;

if the placement height of the object to be cleaned is 80-110mm, presetting the inlet water level to be 110 mm;

if the placement height of the object to be cleaned is 140mm above 110-;

if the placement height of the object to be cleaned is 170mm above 140-;

if the placing height of the object to be cleaned is higher than 170mm, the water inlet level is preset to be 180 mm.

In a specific embodiment, the steps S2 and S3 further include:

and in response to the determination that the drainage module is opened, generating a first control signal and sending the first control signal to the drainage module to control the drainage module to be closed.

Specifically, the drainage module can be a drainage electromagnetic valve, and corresponds to a drainage starting state under the condition that the drainage module is opened; under the condition that the drainage module is closed, the drainage module is required to be closed before water enters corresponding to the state of stopping drainage, so that drainage is stopped, and water resource waste is avoided.

In a specific embodiment, step S3 specifically includes:

s31, in response to the fact that the drainage module of the water tank is determined to be closed, generating a second control signal and sending the second control signal to the water inlet module to control the water inlet module to be opened, acquiring a third image in a cleaning area in the water inlet process, determining a water inlet line according to the third image, comparing the water inlet line with a preset reference line to determine an actual water inlet level, and/or calculating the actual water inlet level by combining the water inlet flow, the water inlet time, the category of the object to be cleaned and the area of the bottom surface of the water tank, wherein the water inlet flow, the water inlet time, the category of the object to be cleaned and the area are acquired by a flowmeter;

and S32, responding to the fact that the actual water inlet level in the water tank reaches the preset water inlet level within the preset water inlet time, generating a third control signal and sending the third control signal to the water inlet module to control the water inlet module to be closed, generating a fourth control signal according to the cleaning and purifying modes and a second relation to control the corresponding cleaning and purifying devices to be opened, and recording the opening duration of the equipment, wherein the second relation is used for representing the corresponding relations between the different cleaning and purifying modes and the opening and closing and working modes of the different cleaning and purifying devices.

Specifically, the water inlet module can be a water inlet electromagnetic valve, and corresponds to a starting water inlet state under the condition that the water inlet module is opened; and in the case that the water inlet module is closed, the state of stopping water inlet is corresponded. The method for determining the actual water inlet level of the present application includes the following two methods:

(1) and determining a water inlet line according to the third image, and comparing the water inlet line with a preset reference line to determine the actual water inlet level. The third image can be acquired at fixed time intervals in the water inlet process through the image acquisition device, the water inlet water level lines in different states are obtained according to analysis of the third image, the water inlet water level lines are compared with preset reference lines to determine the actual water inlet level, the preset reference lines are set into a plurality of intervals, if the water inlet water level lines are in the first interval, the corresponding actual water inlet level is L1, if the water inlet water level lines are in the second interval, the corresponding actual water inlet level is L2, and the like.

(2) And calculating the actual water inlet level by combining the water inlet flow, the water inlet time and the area of the bottom surface of the water tank, which are acquired by the flowmeter. The method specifically comprises the following steps:

calculating the actual inlet water level L by adopting the following formula:

L＝a*Q*T/S；

wherein a represents an adjustment parameter, Q represents an inflow rate, T represents an inflow time, and S represents an area of the bottom surface of the water tank.

Specifically, the inflow rate Q can be measured by a flowmeter, and the inflow time T is recorded from the water inflow module of the opened water tank. The adjustment parameter a can be adjusted according to the volume of waiting to wash the object, because wait to wash the object and place and occupy a part volume in the basin, consequently the inflow (volume) is greater than the volume that covers the corresponding of the water level of waiting to wash the object in the basin, and a is greater than 1, specifically selects or sets up according to actual demand. Specifically, a can be determined according to the category of the object to be cleaned, and different adjustment parameters a correspond to different categories of the object to be cleaned, which are determined by the trained object to be cleaned classification model.

In one embodiment, when the category of the objects to be cleaned is vegetables, the actual water inlet level is calculated according to the adjustment parameter a of green leaves being 1.1;

in one embodiment, when the class of the object to be cleaned is a block class, the actual water inlet level is calculated according to the adjustment parameter a of the block class being 1.05;

in one embodiment, when the category of the object to be cleaned is cylindrical tubers, the actual water inlet level is calculated according to the tuber adjustment parameter a which is 1.2.

The actual water inlet level can be obtained through real-time measurement by the above formula, and whether the actual water inlet level reaches the preset water inlet level can be further judged subsequently. The actual water level of intaking is calculated to the classification that combines the waiting to wash the thing that flowmeter and above-mentioned image analysis obtained, and the classification that treats the washing thing according to the difference corresponds different adjustment parameter, and real-time actual water level of intaking can be obtained in very accurate measurement, and the process of intaking is controlled to the accuracy, avoids appearing the water waste.

But adopt the mode real-time detection of the actual water level of intaking of third image definite, the rate of accuracy is high, adopts the flowmeter to judge the mode reliable and stable of the actual water level of intaking according to the inflow, realizes easily, can adopt more than one of them mode, perhaps adopts more than two kinds simultaneously. And comparing the actual water inlet level with the preset water inlet level determined according to the placing height of the objects to be cleaned in the step S2, and controlling the opening or closing of the water inlet module according to the comparison result. If the actual water inlet level does not reach the preset water inlet level, the water inlet module is controlled to be kept opened, and if the actual water inlet level reaches the preset water inlet level, the water inlet module is controlled to be closed.

In a specific embodiment, step S3 further includes: and responding to the fact that the actual water inlet level does not reach the preset water inlet level and the water inlet time exceeds the preset water inlet time, generating an eighth control signal and sending the eighth control signal to the early warning module, and controlling the early warning module to send out a water shortage early warning instruction.

Specifically, if the actual water inlet water level does not reach the preset water inlet water level after the water inlet time reaches the preset water inlet time, the water inlet flow is insufficient, the water is in a water shortage state, and therefore a water shortage early warning indication needs to be sent to remind a user.

Further comprising:

and S4, controlling the corresponding cleaning and purifying device to start to work in the cleaning and purifying mode.

Specifically, different washing purification mode corresponds to starting different washing purifier, and as an example, purification mode corresponds to starting water catalyst module, photocatalyst module, ultrasonic module and air pump, and rinsing mode corresponds to starting ultrasonic module gentleness. When the category of the object to be cleaned is fruit, the fruit cleaning device enters a purification mode, adopts the water catalyst module, the photocatalyst module, the ultrasonic module and the air pump to sterilize the fruit, remove pesticide residues and remove dirt on the surface of the fruit, and then enters a rinsing mode, and adopts the ultrasonic module and the air pump to clean residual reactants. In other embodiments, when the cleaning and purifying modes are different, other different cleaning and purifying devices can be correspondingly started.

In a specific embodiment, step S5 specifically includes:

s51, responding to the device starting duration time to reach the preset time, generating a fifth control signal to control the cleaning and purifying device to be closed, generating a sixth control signal and sending the sixth control signal to the drainage module to control the drainage module to be started;

Specifically, a drainage water level line is determined according to the second image, and the drainage water level line is compared with a preset reference line to determine an actual drainage water level. The second image can be acquired by the image acquisition device at fixed time intervals in the drainage process, the drainage water level lines in different states are acquired according to analysis of the second image, the drainage water level lines are compared with preset reference lines, the actual drainage water level is determined, the preset reference lines are set to be a plurality of intervals, if the drainage water level lines are in a third interval, the corresponding actual drainage water level is L3, if the drainage water level lines are in a fourth interval, the corresponding actual drainage water level is L4, and the like. The preset drainage water level can be 0, the actual drainage water level is compared with the preset drainage water level, and whether the drainage module is closed or not is determined according to the comparison result. And if the actual drainage water level does not reach the preset drainage water level, controlling the drainage module to be kept opened, and if the actual drainage water level reaches the preset drainage water level, controlling the drainage module to be closed.

In a specific embodiment, step S5 further includes: and in the drainage process, the variation value of the drainage water level line in the second image acquired at different moments is smaller than the threshold range, and/or in response to the fact that the drainage water level does not reach the preset drainage water level and the drainage time exceeds the preset drainage time, a ninth control signal is generated and sent to the early warning module, and the early warning module is controlled to send out a drainage fault indication.

Specifically, in the drainage process, whether drainage is normal or not can be judged according to the change of drainage water lines in two successive sets of second images collected at different moments. If the change values of the drainage water level lines in the second images acquired at two successive different moments are smaller than the threshold range, indicating that drainage is abnormal, and generating a ninth control signal corresponding to drainage fault indication to the early warning module so as to send out drainage fault early warning; and if the change values of the drainage water level lines in the second images collected at two successive groups of different moments are larger than the threshold range, indicating that the drainage is normal, and not generating a ninth control signal.

If after the drainage time reaches the preset drainage time, the actual drainage water level still does not reach the preset drainage water level, the inflow is insufficient, the water shortage state is achieved, and therefore the water shortage early warning indication needs to be sent out to remind a user.
