Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.

Referring to fig. 1, fig. 1 is a flowchart of a method for controlling a dishwasher according to a first embodiment of the present invention, as shown in fig. 1, the method for controlling the dishwasher including the steps of:

step S1: acquiring an image of tableware in the dishwasher;

step S2: determining the characteristics of the dishware from the image:

step S3: and controlling a spray arm of the dishwasher to wash the tableware according to the characteristics.

Wherein, the "image" of the tableware in step S1 can be obtained by using a camera; for example, the CDD industrial camera can be implemented by: through placing the camera in the dish washer, shoot the tableware in the dish washer through controlling the camera to acquire the image of tableware.

It can be understood that since the user usually has a messy place of the dishware in the dishwasher, the user needs to shoot the image of the dishware in all directions, in this embodiment, the type and installation position of the camera are not limited in the method, and the user only needs to be able to acquire the images of the dishware placed in the dishwasher in all directions; exemplary are as follows: the camera can be arranged in a plurality of directions to acquire images of the tableware in the dish-washing machine, or the camera can be arranged to rotate 0-360 degrees to acquire images of the tableware in the dish-washing machine, or the panoramic fisheye camera is adopted to acquire all images of the tableware in the dish-washing machine.

The "characteristic" of the tableware in step S2 may be at least one of the type of the tableware, the number of the tableware, the material of the tableware, the location of the tableware, and the surface cleanliness of the tableware.

It will be appreciated that the "types" of cutlery described above may be classified according to their function, such as bowls and chopsticks, cups, spoons, etc., as exemplary; the tableware can also be classified according to the shape and the size of the tableware, such as a round disc, a square dish and the like; the classification may be performed in other manners, and the classification manner is not limited. The method for identifying the type of the tableware can adopt contour identification and feature identification to determine the content of the contour of the tableware according to the data corresponding to the contour of the tableware image, thereby determining what tableware is. Exemplary are as follows: generally, the goblets are provided with finger cup holders which stand on a long and thin foot, so that the long and thin foot and the finger cup holder are preset as unique characteristics of the goblets, and when a user puts in the goblets, the type of the goblets is judged according to the acquired image contour and the characteristics of the goblets.

Further, the "material" of the tableware may be classified into metal such as wood, ceramics, glass, plastics, copper, iron, aluminum, etc., or alloy such as stainless steel; the tableware material can be identified by adopting the reflecting degree of the tableware and combining the type of the tableware, firstly, the approximately usable material range can be analyzed according to the type of the tableware image, the goblet can only be glass or crystal, further, a specific light source is provided in the dish-washing machine, the material of the tableware is identified through an illumination model due to the fact that different materials reflect light differently, and in some embodiments, the texture of the tableware can be further integrated for analysis, such as: and according to the tableware image of the goblet under a specific light source, calculating coefficients of an environment illumination component, a diffuse reflection illumination component, a specular reflection component and a reflectivity component by using an illumination model, thereby identifying whether the glass or the crystal to which the tableware belongs.

Further, the surface cleanliness of the tableware can be obtained by extracting oil stain as a contour after the gray scale of a tableware image is binarized, and obtaining the cleanliness of the surface of the tableware according to the ratio of black pixel points reflected by the oil stain to the whole area of the tableware or directly according to the area occupied by the oil stain; exemplary are as follows: 1. carrying out grey level binarization on the tableware image; 2. separating the greasy dirt part of the tableware by local threshold separation; 3. calculating the proportion value of the oil stain part in the whole tableware area; 4. and comparing the ratio value with a preset threshold value to obtain the surface cleanliness. Exemplary are as follows: the proportion value of the oil stain part to the whole tableware area is 50 percent as one threshold value, when the proportion value is lower than the threshold value, the tableware is judged to be cleaner, otherwise, when the proportion value exceeds the threshold value, the tableware is judged to be dirtier.

Similarly, the "number" of the tableware can be obtained by performing target extraction analysis according to the tableware image, such as extracting the tableware outline, or according to the user's own input.

Wherein the "position" of the dishware may be obtained from a washing position in the dishwasher where the dishware image profile falls, such as for example: 1. establishing a coordinate system; 2. dividing a washing area of the dishwasher into at least four quadrants according to a coordinate system; 3: and obtaining the cleaning area where the tableware is located according to the proportion of the specific space occupied by the tableware image in the quadrant. I.e., the position of the dishes, it is understood that the entire washing area is divided into at least four quadrants, i.e., four spaces, and when the dishes are located at two quadrants at the same time, the quadrant with the largest dish ratio is taken as the quadrant where the dishes are located, as exemplified by: if the tableware accounts for 70% of the space in the first quadrant and 30% of the space in the second quadrant; the utensil is identified as being in the first quadrant.

By the above, the characteristics of the dish washing machine where the tableware is located, such as goblets-2-glass-first quadrant-cleaner can be obtained.

In step S3, the spray arm of the dishwasher is controlled to clean the dishes according to the characteristics, wherein the spray arm is controlled by a controller, which may be any one of a programmable single chip, a microcomputer and a chip, or a digital or analog circuit may be used to replace the controller in the present embodiment.

The method that can be used in steps S1 to S3 and the definition of the features are specifically explained above, and steps S1 to S3 are described below using specific examples.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for determining characteristics of a dish according to an image according to a second embodiment of the present invention, and as shown in fig. 2, the method for determining characteristics of a dish according to an image may further include the following steps:

step S201: establishing a cloud database according to a tableware image acquired in advance and a label of the tableware image;

step S202: creating an image recognition model;

step S203: pre-training the image recognition model through a cloud database;

step S204: inputting the acquired tableware images into a pre-trained image recognition model to determine the characteristics of the tableware, wherein the acquired tableware images are uploaded to a cloud database to serve as training samples of the image recognition model.

Fig. 2 illustrates a method for obtaining the image characteristics of the tableware through the image recognition model in step S2, wherein the labels of the images of the tableware collected in advance are the image characteristics of the tableware in step S2, it can be understood that creating the image recognition model for model pre-training requires establishing a cloud database of the images of the tableware collected in advance and the labels of the images of the tableware; the image recognition model can be a neural network model or other models, in the actual use process, a user puts tableware every time, the dish-washing machine is triggered to collect tableware images in a cleaning area of the dish-washing machine, the tableware images are uploaded to a cloud-end database and a local database preset by the dish-washing machine, and the characteristics of the put tableware are determined by using the pre-trained image recognition model.

Further, the user may also choose not to connect to the network and use the image recognition model directly with the local database to determine the characteristics of the placed cutlery. Because the tableware image information in the local database is less and is only the tableware image collected by the dishwasher used by the user, the characteristic of the placed tableware is determined by using the image recognition model by adopting the local database, the time for recognizing by the image recognition model can be reduced, and the efficiency of calculating by the image recognition model is improved.

Through the established cloud database, users in various places can upload tableware images shot in dish washers of the users to the cloud database, and the tableware images serve as training samples of the image recognition models to be trained, so that the established image recognition models can be continuously trained and optimized by the tableware images; therefore, the accuracy and the recognition range of the image recognition model are improved; exemplary are as follows: the tableware used by the user is not frequently replaced under the common condition, so that the image recognition model can finish recognition by adopting a local database, and if the user replaces or adds other tableware, the image recognition model can also be ensured to accurately judge the characteristics of the tableware, the probability of misjudgment in the recognition process is reduced, and the reliability of the dish washing machine is improved.

Based on the second embodiment, in another embodiment provided by the present invention, the cloud database may be further used, the background staff may collect the feedback of each dishwasher by collecting the feedback of each dishwasher, specifically, after the spraying arm of each dishwasher is controlled to clean the dishware, the surface cleanliness of the dishware and the feedback of the user, the background staff improves the program for controlling the spraying arm of the dishwasher by the information, and downloads the program to each dishwasher by means of OTA (Over-the-Air Technology: Over-the-Air download) to update the dishwasher; the benefits of this approach are: the user can continuously update the operation mode of the dishwasher so as to adapt to the continuously improved appearance of the tableware or add new functions. The method solves the problem of loophole or error in the operation of the prior dish washer, increases the stability and well supports a new operating system.

Referring to fig. 3, fig. 3 is a flowchart illustrating a method for washing dishes by controlling a spray arm of a dishwasher according to characteristics of a third embodiment of the present invention, as shown in fig. 2, the step S3 of controlling the spray arm of the dishwasher to wash dishes according to the characteristics may specifically include the following steps:

step S301: determining a cleaning area where the tableware is located;

step S302: when the spray arm is used for cleaning the cleaning area where the tableware is located, the spray arm is controlled to clean the tableware according to the characteristics of the tableware.

Wherein, in step S301, that is, in step S2, the "position" of the tableware is determined according to the position characteristics of the tableware in the cleaning area, and further according to the characteristics of the tableware in different cleaning areas, the spray arm can be used for cleaning the cleaning area where the tableware is located according to the characteristics of the tableware when the tableware is cleaned; exemplary are as follows: the cleaning area is divided into a first quadrant, a second quadrant, a third quadrant and a fourth quadrant, and if tableware is detected not to exist in the first quadrant, the spray arm can be controlled to stop spraying water for cleaning in the first quadrant. The advantages brought by this mode are that: the spray head can be selectively cleaned according to the position characteristics of the tableware, and the tableware is purposefully cleaned by identifying the real-time cleaning position of the tableware and controlling the operation action of the spray head through a preset program.

In step S302, controlling the spray arm of the dishwasher to clean the dishes according to the characteristics may specifically include:

adjusting at least one of the following of the spray arm according to the characteristic of the dish: water outlet angle, water outlet quantity, water outlet pressure, cleaning time, water outlet temperature, spray arm rotating speed and spray arm movement stroke.

The spray arm can be divided into two cases, namely movable spray arm and immovable spray arm.

A: when the spray arm is immovable, namely when the spray arm is fixedly arranged; controlling the spray arm of the dishwasher to wash the dishes according to the characteristics comprises: adjusting at least one of the water yield, the water outlet pressure, the cleaning time and the water outlet temperature of the spray arm according to the characteristics;

it can be understood that according to the characteristics of the tableware, namely the cleaning area where the tableware is located, the type of the tableware, the quantity of the tableware, the material of the tableware and the surface cleanliness of the tableware, different water outlet angles, water outlet amounts, water outlet pressures, cleaning time and water outlet temperatures of the water outlet holes are set; the method can be as follows:

1. setting the water outlet temperature of the matched tableware corresponding to the type and material of the cleaning area where the tableware is located and the water spray holes of the area;

that is, the tableware in the washing area can be washed at a proper water temperature by the material and the type of the tableware in the washing area, such as: when plastic materials are detected in tableware in a certain quadrant of a cleaning area, in order to avoid plastic deformation caused by high temperature, the temperature is too low to meet the requirements of disinfection and cleaning, so that the tableware is cleaned at the optimal proper temperature, and the temperature of water sprayed out of hole sites corresponding to the quadrant is controlled to be 50-70 degrees, wherein the temperature is set by a worker through experiments in advance;

2. corresponding to the surface cleanliness and the quantity of the cleaning area where the tableware is located, and corresponding to the water spraying holes in the area, the water outlet quantity, the water outlet pressure and the cleaning time of the tableware are adapted;

the cleaning difficulty in the region is comprehensively obtained according to the surface cleanliness and the quantity of the tableware in the cleaning region, and different cleaning strengths are set according to different cleaning difficulties, such as: and if the condition that the quantity of the tableware in a certain quadrant of the cleaning area is large and the surface cleanliness is poor is detected, the water quantity and the water outlet pressure of the quadrant of the cleaning area are increased, and the cleaning time is prolonged.

For the above "cleaning difficulty", the specific calculation method may be as follows: "difficulty in cleaning" can be found on a weighted average of the number of dishes and surface cleanliness, as exemplified by: the number of the tableware in a certain quadrant is 2, the surface cleanliness of two tableware is defined as 0.3 according to the tableware image, if the ratio of the black pixel dot area reflected by oil stains to the whole tableware area is 30%, the clear difficulty in the clear area is converted into a value of 2 x 0.3 x k, wherein k is a weighted average coefficient. After the values converted by the cleaning difficulty of the cleaning area are obtained, the water yield, the water outlet pressure and the cleaning time of the spray arm are correspondingly controlled by presetting different cleaning difficulty values, and the method comprises the following steps: the cleaning difficulty is converted into a numerical value and then is 0.7, namely the corresponding water yield, the corresponding water outlet pressure and the corresponding cleaning time are respectively 0.5l/s, 0.13Mpa and 15 s.

Through the above, when the spray arm is unmovable, according to the tableware characteristics in each washing area, the spray arm carries out the pertinence and sprays in the washing area of difference, and the adjustment that adaptability was carried out to water yield, water outlet pressure, cleaning time, play water temperature promptly, carries out the pertinence washing to different tableware through this kind of mode, avoids when the abluent tableware of dishwasher single is too little, causes the condition that dishwasher is long-consuming, the washing is dirty, waste the electric energy to make the shower nozzle can the pertinence water spray, exemplary if: when tableware is not placed in a certain area, the spray pipe does not spray the spray holes corresponding to the area for cleaning, so that water energy is saved, on the other hand, for other areas where the tableware is placed, the spray pipe can concentrate water pressure under preset program control, even adjusts the temperature for cleaning, and is specifically judged according to the characteristics of the tableware in the area, for example, the types or the materials of the tableware difficult to clean can increase the water pressure or adjust the temperature, and in the way: the washing efficiency is improved, meanwhile, the universality of the dish washing machine is improved, the dish washing machine is suitable for tableware of various types and materials, users do not need to classify the tableware by themselves, the tableware does not need to be placed specifically, the washing effect can be guaranteed, and the requirements of the users are better met.

B: when the spray arm is movable, controlling the spray arm of the dishwasher to wash the dishes according to the characteristics includes: and adaptively adjusting at least one of the water outlet quantity, the water outlet pressure, the cleaning time and the water outlet temperature of the spray arm according to the characteristics, and adaptively adjusting at least one of the water outlet angle, the rotating speed and the moving stroke of the spray arm.

It can be understood that when the spray arm is movable, according to the tableware image characteristics, besides adjusting at least one of the water outlet quantity, the water outlet pressure, the washing time and the water outlet temperature of the spray arm, at least one of the water outlet angle of the spray arm, the rotation speed of the spray arm and the movement stroke of the spray arm can be adjusted, that is, the tableware can be specifically washed by controlling the movement of the spray arm. The movement of the spray arm is driven by the controller, and the movement form does not relate to the technical range which can not be realized by the prior art, so that the method of the second embodiment of the invention is not excessively described.

When the spray arm moves, the two conditions of rotation and translation are described;

controlling the spray arm of the dishwasher to wash the dishes according to the characteristic when the spray arm is rotatable further comprises: controlling the spray arm to rotate in a reciprocating manner so that the spray arm only discharges water in a cleaning area where tableware is placed;

it can be understood that, according to the image information of the dishes, if there are no dishes in the washing area, the spray arm does not rotate to the area, but is limited to rotate back and forth only in the area of the washing area where the dishes are placed; thereby saving electric power and water energy, accelerating the cleaning speed, reducing the time required by cleaning and increasing the satisfaction degree of users.

The rotating direction of the spray arm is not limited, the spray arm can rotate horizontally or vertically, and only the requirement that all cleaning areas can be covered in the cleaning process is met.

Further, when the spray arm can translate, the spray arm is controlled to reciprocate in a cleaning area where tableware is placed, namely, the spray arm can reciprocate up and down or reciprocate left and right, and in the same way, the spray arm plays a role in saving energy and accelerating efficiency by saving a motion path.

Further, controlling the spray arm of the dishwasher to wash the dishes according to the characteristic further comprises:

when the water discharged from the spray arm is in the region which is difficult to clean, at least one of the rotating speed of the spray arm, the water discharge amount and the water discharge pressure is reduced; when the water discharged from the spray arm is in the easy-to-clean area of the tableware, at least one of the rotation speed of the spray arm is increased, the water discharge amount is reduced and the water discharge pressure is reduced; and/or

When the water discharged from the spray arm is in the region which is difficult to clean, at least one of the moving speed of the spray arm, the water discharge amount and the water discharge pressure is reduced; when the water discharged from the spray arm is in the easy-to-clean area of the tableware, at least one of the moving speed of the spray arm is increased, the water discharge amount is reduced, and the water discharge pressure is reduced.

It can be understood that, when the spray arm is rotatable, when rotating to the cleaning area with higher cleaning difficulty, the spray arm reduces the rotating speed so as to increase the time required for cleaning the area, and simultaneously increases the water yield and increases the water outlet pressure so as to increase the cleaning force, otherwise, when rotating to the cleaning area with lower cleaning difficulty, the time required for cleaning the area is reduced, when the spray arm can move horizontally, the same as the above, namely, when moving to the cleaning area with higher cleaning difficulty, the moving speed is reduced, the cleaning force is increased, when moving to the cleaning area with lower cleaning difficulty, the time required for cleaning the area is reduced, and the cleaning force is reduced.

Setting a water outlet angle matched with the tableware corresponding to the position of the cleaning area where the tableware is located and the water spray holes of the area;

that is, by controlling the water outlet angle, the tableware can be washed at the optimal water outlet angle, such as: the user assumes that the tableware is placed at an arbitrary angle, if the tableware is placed upwards at 45 degrees, the water outlet angle of the spraying arm can be adjusted according to the position of the tableware, and if the tableware is placed at 135 degrees, the water is discharged and the tableware is washed on the front side;

wherein, the mode of controlling out water angle can be: the spray arm is controlled to rotate by a preset angle, so that the angle of the spray hole on the spray arm is changed.

In summary, the first to third embodiments of the present invention provide a method for controlling a dishwasher, which determines characteristics of tableware through images of the tableware in the dishwasher, and further controls a spray arm to perform targeted washing through the characteristics of the tableware, wherein the spray arm can adjust a water outlet angle, a water outlet amount, a water outlet pressure, a washing time, a water outlet temperature, a spray arm rotation speed, a spray arm movement stroke and the like according to the characteristics of the tableware, so as to achieve targeted spraying, thereby achieving energy saving, speeding up washing efficiency, increasing versatility of the dishwasher, and improving satisfaction of users.
