Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Before the cleaning operation is executed, the embodiment of the invention can determine the turbidity level of the tableware to be cleaned by acquiring the initial turbidity value of the water body for cleaning the tableware, executing the pre-cleaning operation on the tableware to be cleaned through the water body, detecting the comparative turbidity value of the water body after the pre-cleaning operation, and determining the turbidity level of the tableware to be cleaned according to the difference degree between the comparative turbidity value and the initial turbidity value, wherein if the difference between the comparative turbidity value and the initial turbidity value is larger, the higher the corresponding turbidity level is, the more kitchen residues on the surface of the tableware to be cleaned are shown, and the larger the cleaning difficulty is, so that the cleaning mode matched with the turbidity level can be selected through the turbidity level, and the cleaning operation is executed on the tableware to be cleaned based on the cleaning mode, thereby realizing the purpose of automatically configuring the cleaning mode, solving the problem that the existing determining method of the cleaning mode mainly executes the default cleaning mode through the manual setting, can not automatically adjust according to the dirty degree of the tableware to be cleaned, thereby increasing the operation steps of users and reducing the cleaning efficiency.
In the embodiment of the invention, the execution subject of the process is a dishwasher. The dishwasher is provided with a data processing module, the data processing module is used for processing information fed back by each sensor or data acquisition device and automatically selecting a cleaning mode, and the data processing module can be a microprocessor such as a single chip microcomputer. Fig. 1 shows a flowchart of an implementation of the method for determining a cleaning mode according to the first embodiment of the present invention, which is detailed as follows:
in S101, if a washing start instruction is received, an initial turbidity value before performing a pre-washing operation is collected.
In this embodiment, the user can place the washing intracavity of dish washer with treating the washing tableware to when placing and finishing need treat the washing tableware and wash, the start button through the interactive panel input on the dish washer sends the washing start instruction to the dish washer, of course, if the dish washer disposes communication module, the user can also start through user terminal or remote control equipment remote control dish washer, generate on user terminal or remote control equipment and wash the start instruction, and send the dish washer, with the purpose of realizing remote control dish washer. Optionally, the user may set a washing starting condition, where the washing starting condition may be a time trigger condition, and when the dishwasher detects that the time trigger condition is currently satisfied, a washing starting instruction is generated, and the dishwasher automatically executes a washing process of the dishes to be washed.
In this embodiment, dispose the water storage part in the dish washer, this water storage part can link to each other with the water route of intaking, and after the water intaking valve in the water route of intaking was opened, the water can be through intaking in the water route carries the water storage part, and dish washer can treat through the water that stores in the water storage part that the washing tableware carries out the washing operation. Because the water quality conditions of the water bodies conveyed by different water inlet waterways are different and the water quality conditions at different times can be changed, in order to determine that the pollution degree of the water bodies subjected to pre-cleaning is caused by kitchen residues on the surfaces of tableware or due to the influence of the water quality of the water bodies, the initial turbidity value of the water bodies for cleaning the tableware needs to be determined before the turbidity level of the tableware to be cleaned is determined.
It should be noted that the dishwasher may be provided with a turbidity sensor in the water storage part, by which an initial turbidity value of the water body before the pre-washing operation is performed is determined. The turbidity sensor can be a turbidity sensor based on a voltage signal, the turbidity sensor is provided with two electrodes, when detection is needed, a preset voltage value is loaded on the two electrodes in an internal loop, and a certain amount of ions exist because a water body is not distilled water, so that certain electric conductivity exists, and if the turbidity degree of the water body is higher, the electric conductivity is lower; conversely, the lower the degree of contamination of the water body, the higher the conductivity. Accordingly, the turbidity sensor may collect current values generated by the two electrodes based on the preset voltage and determine an initial turbidity value of the water body based on the current values.
Optionally, in this embodiment, the dishwasher may be provided with a maximum turbidity threshold value, since the dishwasher needs to perform a washing operation on the dishes to be washed through the water in the water storage part, if the degree of turbidity of this water is high, the dishes to be washed cannot be effectively washed, and in this case, the dishwasher needs to perform a filtering operation on the water again. Therefore, if the dishwasher detects that the initial turbidity value is greater than or equal to the maximum turbidity threshold value, the drainage component is opened, the water body is conveyed to the filtering component, and the filtering material in the filtering component is used for filtering and cleaning the water body, so that the cleanliness of the water body is improved.
In S102, a pre-cleaning operation is performed on the dishes to be cleaned through a water body, and the comparative turbidity value of the water body after the pre-cleaning operation is detected.
In this embodiment, before the dishwasher executes the formal washing operation, since the matched washing mode is selected according to the turbidity degree of the tableware, the tableware to be washed needs to be pre-washed, the pre-washing operation specifically includes spraying the water for cleaning on the surface of the tableware at a preset water flow speed, collecting the water after the current spraying operation, and determining the turbidity degree of the tableware according to the turbidity degree of the water after the spraying operation. Preferably, the water flow rate of the pre-washing operation may be greater than that of the formal washing operation, because more kitchen residues may be adhered to the surface of the tableware during the pre-washing operation, and because the temperature is low, the kitchen residues are adhered to the surface of the tableware, and if the water flow rate is low and the water temperature is low, the kitchen residues cannot be washed from the surface of the tableware, thereby reducing the accuracy of the turbidity level identification.
In this embodiment, dish washer can treat through the water in the water storage part and wash the tableware in advance and carry out the washing operation to produce the water after wasing in advance, dish washer can acquire the turbidity value of washing operation back water in advance through turbidity sensor equally, and above-mentioned turbidity value of comparing promptly can confirm the dirty degree of treating the tableware of wasing according to the difference degree of comparing between turbidity value and the initial turbidity value.
Alternatively, in this embodiment, the dishwasher may dispose a turbidity sensor at the water outlet, in which case, before the pre-washing is performed, the dishwasher may open the water outlet of the water storage part for a preset time, convey the water in the water storage part to the water outlet, and acquire an initial turbidity value through the turbidity sensor disposed at the water outlet. And, after carrying out the washing operation in advance, will wash the water after in advance outside the dish washer through the delivery port discharge dish washer, at the in-process of discharge dish washer, can acquire the turbidity value of comparing through the turbidity sensor of delivery port, only need at the delivery port configuration a turbidity sensor can, can realize the multiplexing of turbidity sensor, reduced the required quantity of turbidity sensor, reduced the cost of dish washer.
In S103, determining the turbidity level of the tableware to be cleaned according to the initial turbidity value and the comparison turbidity value.
In this embodiment, the dishwasher may introduce the identified initial turbidity value and the comparison turbidity value into a preset turbidity level conversion function, so as to identify the turbidity level of the dishes to be washed. If the turbidity level is higher, the more kitchen residues on the surface of the tableware to be cleaned are indicated; conversely, a lower turbidity level indicates less kitchen residue on the surface of the dishes to be cleaned. Specifically, the turbidity level transfer function may be:
wherein, ClearStast is the initial turbidity value; CompareDust is the comparative turbidity value, BaseDust is the reference turbidity parameter; BaseLv is a reference turbidity level; DustLv is the turbidity level.
Optionally, in this embodiment, the dishwasher may further obtain a pre-cleaning duration of the pre-cleaning operation, and query a turbidity level conversion function matched with the pre-cleaning duration, because the longer the pre-cleaning duration is, the larger the total amount of the kitchen residues that can be washed away is, the higher the turbidity degree of the water body is, and therefore, in order to improve the accuracy of turbidity level identification, the dishwasher needs to query a turbidity level conversion function matched with the pre-cleaning duration before performing turbidity level conversion.
In S104, a washing mode is configured based on the turbidity level, and a washing operation is performed on the dishes to be washed based on the washing mode.
In this embodiment, the dishwasher is provided with a corresponding relation table of turbidity levels and washing modes, and after calculating the turbidity level corresponding to the dishes to be washed, the corresponding relation table can be queried to determine the washing mode to be executed.
In this embodiment, the cleaning mode includes a cleaning process, such as a cleaning script, including a plurality of cleaning links and a triggering sequence of each cleaning link. The dish washing machine can sequentially execute each cleaning link according to the cleaning flow, thereby realizing the purpose of cleaning the tableware to be cleaned. Optionally, the washing pattern may also include a cyclic sequence of washing sequences to be performed, and a dosage value of detergent to be added during the washing process.
As can be seen from the above, before the cleaning operation is performed, the method for determining the cleaning mode according to the embodiment of the present invention may obtain the initial turbidity value for performing the pre-cleaning operation, perform the pre-cleaning operation on the dishes to be cleaned through the water body, detect the comparative turbidity value of the water body after the pre-cleaning operation, and determine the turbidity level of the dishes to be cleaned according to the comparative turbidity value and the difference degree between the initial turbidity value, where if the difference between the comparative turbidity value and the initial turbidity value is larger, the higher the corresponding turbidity level is, it indicates that there are more kitchen residues on the surface of the dishes to be cleaned, and the greater the cleaning difficulty is, so that the cleaning mode matched with the turbidity level may be selected, and the cleaning operation is performed on the dishes to be cleaned based on the cleaning mode, thereby achieving the purpose of automatically configuring the cleaning mode. Compared with the existing determining mode of the cleaning mode, the manual configuration of a user is not needed, the user only needs to place the tableware to be cleaned in the washing cavity of the dish washing machine, the dish washing machine can automatically configure the cleaning mode according to the turbidity comparison value obtained by the pre-cleaning operation, the operation efficiency of the dish washing machine is improved, the operation of the user is reduced, and the use experience of the user is improved.
Fig. 2 shows a flowchart of a specific implementation of the cleaning mode determining method S104 according to the second embodiment of the present invention. Referring to fig. 2, with respect to the embodiment described in fig. 1, a method S104 for determining a cleaning mode provided in this embodiment includes: s1041 to S1042 are specifically described as follows:
further, the configuring a washing mode based on the turbidity level and performing a washing operation on the dishes to be washed based on the washing mode includes:
in S1041, inquiring a corresponding relation table between preset turbidity levels and washing parameters, and acquiring washing parameters related to the turbidity levels; the flush parameters include a number of flushes.
In the present embodiment, the washing parameter of the washing mode of the dishwasher includes the number of washing times, and if the turbidity level is higher, the number of washing operations that need to be performed is larger; if the turbidity level is low, the number of rinsing operations that need to be performed is small. The dishwasher can be pre-configured with the corresponding relation table according to the relation between the turbidity level and the washing frequency, and the dishwasher can query the washing parameters related to the turbidity level identified in the corresponding relation table when configuring the washing mode. It should be noted that the rinsing parameters include the number of rinsing cycles, based on which the dishes to be cleaned are rinsed in a plurality of cycles.
In this embodiment, the flushing time length of each flushing operation may be the same or different. Optionally, in this embodiment, the washing parameters further include a washing duration, and the dishwasher configures the washing duration corresponding to the washing duration for the washing operations of different washing sequences. Because when washing for the first time, the surface of treating washing tableware includes a large amount of remaining kitchen utensils, consequently washes the operation of washing that the order is more forward, and the washing time is longer, and washes the operation of washing that the order is later, because remaining kitchen utensils are less, can shorten and wash for a long time this moment, when washing effect can be guaranteed to time length through the change washing, also can reduce the energy consumption of dish washer and the cleaning efficiency of dish washer. Preferably, the dishwasher may be configured with an adjustment step size, and the dishwasher may acquire a maximum washing duration, set the maximum washing duration as the washing duration of the washing operation with the washing order of 1, and sequentially obtain the washing durations of the subsequent washing orders based on the adjustment step size, thereby achieving the purpose of automatically configuring the washing duration.
In S1042, performing N times of washing operations on the dishes to be washed according to the washing times within the washing parameters; the value of N is the number of flushes.
In this embodiment, the dishwasher may configure a washing mode according to the washing parameters, and during the washing operation, may perform a plurality of washing operations on the dishes to be washed according to the washing times recorded in the washing parameters in the washing mode, where the number of washing operations performed matches the washing times.
In the embodiment of the invention, the washing times corresponding to the turbidity levels are selected, and the tableware to be washed is subjected to multiple circulating washing operations, so that the washing operation can be matched with the dirt degree of the tableware, the aim of automatically configuring washing parameters is fulfilled, and the accuracy of the configuration of the washing mode is improved.
Fig. 3 shows a flowchart of a specific implementation of the method S1042 for determining a cleaning mode according to a third embodiment of the present invention. Referring to fig. 3, with respect to the embodiment described in fig. 2, a method S1042 for determining a cleaning mode provided in this embodiment includes: s301 to S305 are specifically described as follows:
further, the rinse parameters also include an expected turbidity range after each rinse operation; the step of executing N times of washing operation on the tableware to be washed according to the washing times in the washing parameters comprises the following steps:
in S301, performing an nth washing operation on the dishes to be washed, and detecting an actual turbidity value of the water body after the nth washing operation; the value of N is a positive integer which is greater than 0 and less than or equal to N.
In this embodiment, the dishwasher may dynamically adjust the number of times within the washing parameter, in this case, the washing parameter not only records the washing number of times of the washing operation that needs to be performed, but also records an expected turbidity range of each washing operation, that is, the turbidity value of the water body after the current washing operation should be within a preset expected range, so as to compare the turbidity value after the washing operation with the expected turbidity range, and determine whether the adjustment of the washing number of times is needed. Thus, the dishwasher may create a correspondence table between the washing order and the expected turbidity range and add the correspondence table to the washing parameters. It should be noted that the expected turbidity range of each washing operation is related to the initial turbidity range, and the dishwasher may introduce the initial turbidity range into the expected turbidity parametric conversion model, calculate the expected turbidity ranges corresponding to different washing orders, and generate the corresponding relation table.
In this embodiment, the dishwasher washes the tableware to be washed through the water body of the water storage part, acquires the actual turbidity value of the water body after the washing operation, determines the expected turbidity range corresponding to the washing operation from the washing parameter, and compares the actual turbidity range value with the expected turbidity range. If the actual turbidity range value is within the expected turbidity range, the washing times do not need to be adjusted, and the tableware can be continuously washed based on the washing times; otherwise, if the actual turbidity value is outside the expected turbidity range, the operation of S302 is performed.
In S302, if the actual turbidity value is outside the expected turbidity range associated with the nth flush operation, a difference between the actual turbidity value and a boundary value of the expected turbidity range is calculated.
In this embodiment, the dishwasher may indicate that the number of times of washing needs to be adjusted when detecting that the actual turbidity value is outside the expected turbidity range, and if the actual turbidity value is smaller than the lower limit value of the expected turbidity range, it indicates that the cleanliness of the dishes is higher than the expected cleanliness after n times of washing operations, and at this time, the number of times of washing may be reduced; on the contrary, if the turbidity value is larger than the upper limit value of the expected turbidity range, the kitchen residue on the surface of the tableware is still more, and the washing times are increased. In order to determine the number of adjustments, the dishwasher needs to calculate a difference between the actual turbidity value and a boundary value of the expected turbidity range, and if the actual turbidity value is less than a lower limit value of the expected turbidity range, calculate a difference between the actual turbidity value and the lower boundary; if the actual turbidity value is greater than the upper limit of the expected turbidity range, the difference between the actual turbidity value and the upper limit is calculated.
In S303, the difference is introduced into a cleaning coefficient conversion model to obtain a rinsing frequency adjustment coefficient.
In this embodiment, the dishwasher may introduce the difference between the actual turbidity value and the boundary value into a preset washing coefficient conversion model, calculate a washing frequency adjustment coefficient, and if the difference is greater, the corresponding washing frequency adjustment coefficient is greater; conversely, if the numerical value of the difference is smaller, the corresponding flushing frequency adjustment coefficient is smaller. Specifically, the flushing coefficient conversion model may be a hash function, the difference value is imported into the hash function, a hash value corresponding to the difference value is calculated, and the hash value is identified as the flushing frequency adjustment coefficient.
In S304, a remaining number of times of rinsing is determined based on the value of n, and the remaining number of times of rinsing is adjusted by the number-of-times-of-rinsing adjustment coefficient.
In this embodiment, the dishwasher may calculate a difference between the total number of times of washing N and N according to the washing order N of the currently performed washing operation, determine the current remaining number of times of washing, and adjust the remaining number of times of washing by the washing number adjustment coefficient calculated in S303. Specifically, if the actual turbidity value is greater than the upper limit value of the expected turbidity range, the corresponding washing frequency adjustment coefficient is a positive integer, and the remaining washing frequency needs to be increased; otherwise, if the actual turbidity value is smaller than the lower limit value of the expected turbidity range, the corresponding washing frequency adjustment coefficient is a negative integer, and the remaining washing frequency needs to be reduced.
In S305, a rinsing operation is performed on the dishes to be washed based on the adjusted remaining number of times of rinsing.
In this embodiment, the dishwasher may continue to perform the washing operation on the dishes based on the adjusted remaining number of times of washing after the remaining number of times of washing is adjusted. In particular, if the adjusted remaining number of times of rinsing is 0, it means that no further rinsing is needed, and at this time, the next stage of operation, such as drying, sterilization, etc., may be performed based on the operation flow of the cleaning mode.
In the embodiment of the invention, the actual turbidity value of the water body is collected in the circulating washing process, and whether the washing frequency needs to be adjusted or not is judged, so that not only can the tableware be washed cleanly, but also the washing frequency can be reduced, the energy consumption and the water resource can be reduced when the washing effect is better than the expected effect, and the purposes of energy conservation and environmental protection are realized.

further, after the pre-cleaning operation is performed on the tableware to be cleaned through the water body and the comparative turbidity value of the water body after the pre-cleaning operation is detected, the method further comprises the following steps:
in S401, analyzing the type of the kitchen residues contained in the water body after the pre-cleaning operation.
In this embodiment, the dish washer can be provided with camera module in water outlet department, after dish washer carries out the pre-cleaning operation to the tableware, the water can be outside through the delivery port discharge dish washer, the dish washer can control camera module this moment and acquire the environment image of delivery port department with preset acquisition time interval, through carrying out image analysis to the environment image, the object information that this environment image contains is discerned, confirm the object type of each object information, and extract the object that belongs to the meal kitchen residue in the object information list, thereby obtain the type of each meal kitchen residue.
In S402, a target detergent is selected from a plurality of candidate detergents in the detergent storage part according to the types of all the kitchen residues.
In the present embodiment, the dishwasher is provided with a detergent storage part, and a user may previously add different types of detergents, such as a detergent for removing oil stains, a detergent for bleaching dishes, a detergent for removing odor, and the like, in different storage regions of the detergent storage part. After determining the type of the kitchen residues contained in the washing operation, the dishwasher may select one or more target detergents from a plurality of different types of candidate detergents stored in the cleaning storage part, and perform a subsequent washing operation by the target detergents.
Alternatively, in the embodiment, the dishwasher may determine the mixing ratio of each candidate detergent according to the quantity ratio of different types of meal residues in the tableware residues, and mix a plurality of candidate mixers to obtain the target detergent.

in S403, a washing mode is configured based on the turbidity level and the target detergent, and a washing operation is performed on the dishes to be washed based on the washing mode.
In this embodiment, after the dishwasher determines the target detergent, the dishwasher may select a corresponding reference washing sample based on the turbidity level, and then add the type of the target detergent to the reference washing sample to generate a washing pattern, so that in a subsequent washing operation, the dishwasher may select the corresponding target detergent from the detergent storage part for a cleaning operation.
In the embodiment of the invention, the type of the kitchen residues contained in the water body is analyzed, and the corresponding target cleaning agent is selected, so that the cleaning degree of the cleaning operation can be improved.
Fig. 5 is a flowchart illustrating a specific implementation of the cleaning mode determining method S104 according to a fifth embodiment of the present invention. Referring to fig. 5, with respect to the embodiment described in fig. 1, a method S104 for determining a cleaning mode provided in this embodiment includes: s501 to S503 are specifically detailed as follows:

In this embodiment, the dishwasher may be provided with a temperature sensor, the temperature sensor is used to collect the surface temperature of the dishware to be cleaned, and if the surface temperature of the dishware to be cleaned is lower, the adhesion between the stains and the dishware is higher, and the cleaning difficulty is higher; on the contrary, if the surface temperature of the tableware to be cleaned is higher, the stain solidification effect is lower, and the cleaning difficulty is smaller, so that the cleaning mode corresponding to the surface temperature of the tableware to be cleaned and the turbidity level determined after pre-cleaning can be configured. It should be noted that the washing parameters of the washing mode include the temperature of the water body.
In S502, a water body temperature of the water body for washing the dishes to be washed is determined according to the surface temperature and the turbidity level.
In this embodiment, the dishwasher may introduce the surface temperature and the turbidity level of the dishes to be washed into a predetermined water body temperature transfer function, and calculate the water body temperature determined by the two parameters. If the surface temperature of the tableware to be cleaned is lower, in order to better dissolve stains such as oil dirt and the like in the washing process, more heat needs to be absorbed, so that the required water body temperature is higher; on the contrary, if the surface temperature of the tableware to be cleaned is lower, the heat required for dissolving the dirt is less, and the corresponding water body temperature can be lower, based on the corresponding relationship between the surface temperature and the turbidity level and the water body temperature, a conversion function of the surface temperature, the turbidity level and the water body temperature can be created, so that the water body temperature of the water body for cleaning the tableware can be calculated.
