Description

Technical Field

[0001] The present invention relates to the technical field of tableware cleaning, and in particular to a tableware cleaning control method, device, equipment, medium and tableware cleaning equipment. Background Art

[0002] With the improvement of living standards, dishwashers and other tableware cleaning equipment have attracted more and more attention, but the penetration rate is not high. The main reason is that the cleaning effect or cleaning efficiency of tableware cleaning equipment on the market cannot meet the demand.

[0003] Take a dishwasher as an example. When the dishwasher is used, the cleaning efficiency will decrease as the number of dishes increases. For dishes, grease has always been the main stain. When the number of dishes that need to be cleaned by the dishwasher increases, the amount of grease that needs to be handled will also increase. The more grease there is, the more byproducts generated when the grease decomposes, which in turn affects the decomposition efficiency of the grease, causing the detergent's ability to decompose the grease to decrease, thereby reducing the decomposition efficiency.

[0004] When a dishwasher washes more dishes, it usually takes longer and requires increased pump power to clean multiple times in order to achieve the desired cleaning effect. This results in increased water consumption, longer cleaning time, and poor user experience. Summary of the invention

[0005] In view of this, the present invention provides a cleaning control method, device, equipment, medium and tableware cleaning equipment to solve the problems of increased water consumption, prolonged cleaning time and poor user experience of the tableware cleaning equipment when there are more tableware.

[0006] In a first aspect, the present invention provides a tableware washing control method, wherein the tableware washing mode includes a normal cleaning mode and a high-efficiency cleaning mode, and in the high-efficiency cleaning mode, the control method includes:

[0007] Control the addition of detergent for the first stage of cleaning;

[0008] Obtain the light transmittance X of the cleaning solution at the beginning of the first stage of cleaning 11 and the transmittance X of the cleaning solution at the end of the first stage of cleaning 12 ;

[0009] Calculate the oil decomposition efficiency (X 11 -X 12 ) / X 11 And compare it with the preset oil decomposition efficiency A;

[0010] Determine whether (X 11 -X 12 ) / X 11 ≤A;

[0011] If (X 11 -X 12 ) / X 11 ≤A, then add grease decomposer to carry out the second stage of cleaning.

[0012] Beneficial effect: In the high-efficiency cleaning mode, when the grease decomposition efficiency of the cleaning liquid is less than or equal to the preset grease decomposition efficiency, it indicates that detergent cleaning can no longer meet the grease decomposition needs. At this time, a grease decomposer should be added in time to effectively remove the free fatty acids generated by the grease decomposition reaction, thereby achieving the purpose of efficient cleaning of oil stains. In addition, the amount of water used for cleaning does not increase and the cleaning time does not need to be extended, thereby improving the user experience and satisfaction.

[0013] In an optional embodiment, the second stage cleaning includes:

[0014] Obtaining the light transmittance X of the cleaning liquid, and comparing it with the first preset light transmittance Z;

[0015] Determine whether X>Z is satisfied;

[0016] If X>Z is satisfied, the control ends the dishwashing.

[0017] Beneficial effect: The first preset transmittance is the transmittance corresponding to the cleaning liquid without oil stains. When the transmittance X of the cleaning liquid and the first preset transmittance Z satisfy X>Z, it indicates that the tableware has been cleaned, and the tableware cleaning is ended at this time. Using transmittance as the basis for judging the degree of oil stains in the cleaning liquid can accurately and reliably judge the cleaning state, and then perform precise control, thereby improving the accuracy of intelligent control.

[0018] In an optional embodiment, the second stage cleaning further comprises:

[0019] Obtain the transmittance X of the cleaning solution twice within a certain time interval during the cleaning process 21 and X 22 ;

[0020] Calculate the oil decomposition efficiency (X 21 -X 22 ) / X 21 And compare it with the preset oil decomposition efficiency A;

[0021] Determine whether (X 21 -X 22 ) / X 21 >A;

[0022] If (X 21 -X 22 ) / X 21 >A, stop adding grease decomposer and continue cleaning.

[0023] Beneficial effect: After entering the second stage of cleaning, the transmittance of the cleaning liquid is monitored in real time, and the grease decomposition efficiency is calculated based on the transmittance twice before and after a certain time interval. If the grease decomposition efficiency is greater than the preset grease decomposition efficiency, it indicates that the grease decomposition efficiency can meet the needs. At this time, the addition of grease decomposition agent can be stopped, and detergent cleaning can be used. Using this method, the cleaning strategy is adjusted according to the oil pollution of the cleaning liquid, and the control is optimized, which saves grease decomposition agent while meeting the cleaning needs.

[0024] In an optional embodiment, the oil decomposing agent is yeast.

[0025] Beneficial effects: Yeast can quickly decompose fatty acids and is used as a grease decomposer to improve the decomposition efficiency of grease in the cleaning solution, thereby improving the cleaning efficiency and ensuring the cleaning effect while avoiding the problems of increased pump power, increased water consumption and long cleaning time caused by multiple cleanings.

[0026] In an optional embodiment, the grease decomposing agent is Yarrowia lipolytica.

[0027] Beneficial effects: Yarrowia lipolytica can better assimilate the free fatty acids produced by the oil decomposition reaction, making the decomposition reaction more efficient, and then using Yarrowia lipolytica to perform efficient decomposition and improve cleaning efficiency.

[0028] In an optional embodiment, before entering the high-efficiency cleaning mode, the process further includes:

[0029] Get the dirty status of tableware;

[0030] If the dirty state of the tableware reaches the start condition of the high-efficiency cleaning mode, control to start the high-efficiency cleaning mode;

[0031] If the dirty state of the dishes does not reach the start condition of the high-efficiency cleaning mode, the control starts the conventional cleaning mode.

[0032] Beneficial effect: Before entering the high-efficiency cleaning mode, the dirtiness of the tableware is first determined, and the tableware cleaning equipment is controlled to enter the high-efficiency cleaning mode or the regular cleaning mode according to the dirtiness of the tableware, so as to make targeted adjustments and save energy.

[0033] In an optional embodiment, obtaining the dirtiness of the tableware includes: obtaining the light transmittance X′ of the tableware; and the high-efficiency cleaning mode start-up condition includes X′ being less than or equal to a second preset light transmittance t.

[0034] Beneficial effect: The second preset transmittance t is the limit transmittance corresponding to the tableware with a lot of oil and dirt, which requires efficient cleaning. As long as the transmittance is less than or equal to the second preset transmittance, the efficient cleaning mode needs to be used for efficient cleaning of the tableware. The degree of dirtiness of the tableware is first judged according to the transmittance of the tableware, and then it is determined whether to enter the efficient cleaning mode. The control logic is reasonable, avoiding the situation where energy waste is caused by directly entering the efficient cleaning mode.

[0035] In an optional implementation, if X′>t is satisfied, the control starts the conventional cleaning mode.

[0036] Beneficial effect: If the light transmittance of the tableware is greater than the second preset light transmittance, it indicates that the degree of oil stain on the tableware is not serious. At this time, the conventional cleaning mode can meet the cleaning needs.

[0037] In an optional embodiment, the conventional cleaning mode includes:

[0038] The detergent is added for cleaning until the light transmittance X of the cleaning liquid is greater than the first preset light transmittance Z.

[0039] Beneficial effect: In the conventional cleaning mode, only the use of detergent for conventional cleaning can meet the cleaning requirements, and conventional cleaning continues until the transmittance of the cleaning liquid is greater than the first preset transmittance, indicating that the cleaning liquid is already very clear and the cleaning can be completed.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0077] Combine the following Figures 1 to 8 , describing an embodiment of the present invention.

[0078] According to an embodiment of the present invention, on the one hand, Figure 1As shown, a tableware cleaning control method is provided, wherein the tableware cleaning mode includes a conventional cleaning mode and a high-efficiency cleaning mode, and in the high-efficiency cleaning mode, the control method includes:

[0079] Control the addition of detergent for the first stage of cleaning;

[0080] Obtain the light transmittance X of the cleaning solution at the beginning of the first stage of cleaning 11 and the transmittance X of the cleaning solution at the end of the first stage of cleaning 12 ;

[0081] Calculate the oil decomposition efficiency (X 11 -X 12 ) / X 11 And compare it with the preset oil decomposition efficiency A;

[0082] Determine whether (X 11 -X 12 ) / X 11 ≤A;

[0083] If (X 11 -X 12 ) / X 11 ≤A, then add grease decomposer to carry out the second stage of cleaning.

[0084] In the high-efficiency cleaning mode, when the grease decomposition efficiency of the cleaning liquid is less than or equal to the preset grease decomposition efficiency, it indicates that the detergent cleaning can no longer meet the grease decomposition needs and the cleaning speed slows down. At this time, the grease decomposer is added in time to effectively remove the free fatty acids generated by the grease decomposition reaction, thereby achieving the purpose of efficiently cleaning oil stains. There is no need to increase the pump power and the number of cleaning times, the cleaning water consumption does not increase, and the cleaning time does not need to be extended, thereby improving the user experience and satisfaction.

[0085] In some embodiments, Figure 2 As shown, the second stage cleaning includes:

[0086] Obtaining the light transmittance X of the cleaning liquid, and comparing it with the first preset light transmittance Z;

[0087] Determine whether X>Z is satisfied;

[0088] If X>Z is satisfied, the control ends the dishwashing.

[0089] The first preset transmittance is the transmittance corresponding to the cleaning liquid without oil stains. When the transmittance X of the cleaning liquid and the first preset transmittance Z satisfy X>Z, it indicates that the tableware 10 has been cleaned, and the tableware cleaning can be controlled to end at this time. Using transmittance as a basis for judging the degree of oil stains in the cleaning liquid can accurately and reliably judge the cleaning state, and then carry out targeted and precise control, thereby improving the accuracy of intelligent control and enhancing the user experience.

[0090] In some embodiments, Figure 3 As shown, the second stage cleaning also includes:

[0091] If X>Z is not satisfied, obtain the transmittance X of the cleaning solution twice before and after a certain time interval during the cleaning process. 21 and X 22 ;

[0092] Calculate the oil decomposition efficiency (X 21 -X 22 ) / X 21 And compare it with the preset oil decomposition efficiency A;

[0093] Determine whether (X 21 -X 22 ) / X 21 >A;

[0094] If (X 21 -X 22 ) / X 21 >A, stop adding grease decomposer and continue cleaning.

[0095] After entering the second stage of cleaning, the transmittance of the cleaning liquid is monitored in real time, and the grease decomposition efficiency is calculated based on the transmittance twice before and after a certain time interval. If the grease decomposition efficiency is greater than the preset grease decomposition efficiency, it indicates that the grease decomposition efficiency can meet the needs. At this time, the addition of grease decomposition agent can be stopped and detergent cleaning can be used. Using this method, the cleaning strategy is adjusted according to the oil pollution of the cleaning liquid, and the control is optimized to save grease decomposition agent while meeting the cleaning needs.

[0096] In some embodiments, the lipolytic agent is yeast.

[0097] By taking advantage of the characteristic of yeast to quickly decompose fatty acids, yeast is used as a grease decomposer to improve the decomposition efficiency of grease in the cleaning solution, improve the cleaning efficiency, ensure the cleaning effect, and avoid the problems of increased pump power, increased water consumption and long cleaning time caused by multiple cleanings.

[0098] Generally speaking, yeasts such as Candida, Geotrichum, and Pichia can be used as grease decomposers.

[0099] In some embodiments, the lipolytic agent is Yarrowia lipolytica.

[0100] Since Yarrowia lipolytica can better assimilate the free fatty acids produced by the oil decomposition reaction, it will make the decomposition reaction more efficient. Therefore, using Yarrowia lipolytica for efficient decomposition can greatly improve the cleaning efficiency.

[0101] In some embodiments, Figure 4 As shown, before entering the efficient cleaning mode, it also includes:

[0102] Obtaining the dirtiness of the tableware 10;

[0103] If the dirty state of the tableware 10 reaches the start condition of the high-efficiency cleaning mode, the control starts the high-efficiency cleaning mode;

[0104] If the dirty state of the tableware 10 does not reach the start condition of the high-efficiency cleaning mode, the control starts the conventional cleaning mode.

[0105] Before entering the high-efficiency cleaning mode, the dirtiness of the tableware 10 is first determined, and the tableware cleaning device is controlled to enter the high-efficiency cleaning mode or the conventional cleaning mode according to the dirtiness of the tableware 10, so that targeted control adjustments can be made to save energy.

[0106] In some embodiments, Figure 5 As shown, the method of obtaining the dirtiness state of the tableware 10 includes: obtaining the light transmittance X′ of the tableware 10 ; the high-efficiency cleaning mode start-up condition includes X′ being less than or equal to a second preset light transmittance t.

[0107] The second preset transmittance t is the limit transmittance corresponding to the tableware 10 being heavily greasy and requiring efficient cleaning. As long as the transmittance is less than or equal to the second preset transmittance, the efficient cleaning mode needs to be adopted to efficiently clean the tableware 10. The degree of dirtiness of the tableware 10 is first determined according to the transmittance of the tableware 10, and then it is determined whether to enter the efficient cleaning mode. The control logic is reasonable, and the situation of directly entering the efficient cleaning mode and causing energy waste is avoided.

[0108] Further, if X′>t is satisfied, the control starts the normal cleaning mode.

[0109] If the light transmittance of the tableware 10 is greater than the second preset light transmittance, it indicates that the degree of oil stain on the tableware 10 is not serious, and the conventional cleaning mode can meet the cleaning needs.

[0110] In some embodiments, Figure 6 As shown, the conventional cleaning mode includes:

[0111] The detergent is added for cleaning until the light transmittance X of the cleaning liquid is greater than the first preset light transmittance Z.

[0112] In the conventional cleaning mode, only conventional cleaning with detergent can meet the cleaning requirements, and conventional cleaning continues until the transmittance of the cleaning liquid is greater than the first preset transmittance, indicating that the cleaning liquid is already very clear and the cleaning can be completed.

[0113] According to an embodiment of the present invention, on the other hand, Figure 7 As shown, a control device is also provided for executing the tableware washing control method, the control device comprising:

[0114] The acquisition module is used to obtain the transmittance X of the cleaning liquid at the beginning of the first stage of cleaning. 11 and the transmittance of the cleaning solution at the end of the first stage of cleaning X 12 ;

[0115] Calculation module, used to calculate the oil decomposition efficiency (X 21 -X 22 ) / X 21 ;

[0116] A judging module, used to judge whether the grease decomposition efficiency is less than or equal to a preset grease decomposition efficiency;

[0117] The control module is used to control the addition of detergent for the first stage of cleaning and to control the addition of grease decomposition agent for the second stage of cleaning when the grease decomposition efficiency is less than or equal to the preset grease decomposition efficiency.

[0118] The acquisition module is used to obtain the transmittance X of the cleaning solution at the beginning of the first stage of cleaning. 11 and the transmittance of the cleaning solution at the end of the first stage of cleaning X 12 ; The judgment module calculates the grease decomposition efficiency based on the transmittance at the beginning and end of cleaning; the judgment module determines whether the grease decomposition efficiency is less than or equal to the preset grease decomposition efficiency; the control module is used to control the addition of detergent for the first stage of cleaning and to control the addition of grease decomposer for efficient cleaning when the grease decomposition efficiency is less than or equal to the preset grease decomposition efficiency, so as to effectively remove the free fatty acids generated by the grease decomposition reaction and improve the cleaning efficiency.

[0119] According to an embodiment of the present invention, on the other hand, a computer device is provided, including a memory and a processor, wherein the memory and the processor are communicatively connected to each other, computer instructions are stored in the memory, and the processor executes any one of the above-described dishware washing control methods by executing the computer instructions.

[0120] The processor executes the tableware cleaning control method of the present invention by executing computer instructions stored in the memory, and then efficiently cleans the tableware 10 by adding a grease decomposer when the tableware 10 is seriously dirty, effectively removing free fatty acids generated by the grease decomposition reaction, improving the cleaning efficiency, and ensuring the cleaning effect without repeated cleaning.

[0121] According to an embodiment of the present invention, on the other hand, a computer-readable storage medium is provided, on which computer instructions are stored, and the computer instructions are used to enable a computer to execute any of the above-mentioned tableware washing control methods.

[0122] By executing the computer instructions stored on the computer-readable storage medium, the tableware cleaning control method of the present invention can be executed, and then when the tableware 10 is seriously dirty, a grease decomposer can be added to perform efficient cleaning, effectively remove free fatty acids generated by the grease decomposition reaction, and improve the cleaning efficiency and cleaning effect.

[0123] According to an embodiment of the present invention, on the other hand, Figure 8 As shown, a tableware washing device is also provided, which is suitable for executing the tableware washing control method, and the tableware washing device includes:

[0124] The device body 1 has a cleaning chamber formed therein, and tableware 10 can be placed in the cleaning chamber;

[0125] A detergent storage chamber 2 is provided in the device body 1, a detergent outlet of the detergent storage chamber 2 is communicated with the cleaning chamber, and a first switch valve is provided at the detergent outlet;

[0126] A yeast storage chamber 3 is provided in the equipment body 1, a yeast outlet of the yeast storage chamber 3 is communicated with the cleaning chamber, and a second switch valve is provided at the yeast outlet;

[0127] Light transmittance detection sensor 4;

[0128] A controller, wherein the first switch valve, the second switch valve and the transmittance detection sensor 4 are respectively connected to the controller.

[0129] A yeast storage chamber 3 is provided on the device body 1. If yeast as a grease decomposer needs to be added to decompose grease during the dishwashing cleaning process, the controller controls the second switch valve at the yeast outlet to open, and supplies yeast to the cleaning chamber, so as to effectively remove free fatty acids produced by grease decomposition, improve cleaning efficiency, and enhance user satisfaction.

[0130] In some embodiments, the light transmittance detection sensor 4 includes a laser sensor.

[0131] The light transmittance is detected by a laser sensor, which has high detection accuracy, fast response speed, and is also convenient for communication connection with the controller to achieve intelligent control. The laser sensor mainly measures the absorption of laser by grease and uses the scattering or reflection characteristics to judge the grease situation in the cavity at this moment, that is, to measure the light transmittance.

[0132] As Figure 8 shown, the laser sensor placed above the inside of the dishwasher can be used to determine the degree of oil stain on the kitchen utensils inside the dishwasher. The higher the oil stain value, the greater the value feedback by the laser sensor to the controller. There is a kit for placing detergent and yeast powder above the left side of the dishwasher.

[0133] Research shows that when the detergent is cleaning, as the grease decomposition reaction occurs, fatty acids will be produced simultaneously, which will slow down the grease decomposition reaction. When there is less grease, fatty acids will not accumulate in large quantities, and the decomposition efficiency will not decrease significantly. However, when the number of kitchen utensils to be cleaned increases, the accumulation of fatty acids will affect the decomposition efficiency, resulting in a longer working time of the machine and a reduced efficiency. Adding Yarrowia lipolytica at the appropriate time can decompose fatty acids and thus increase the grease decomposition efficiency.

[0134] When there are bowls and chopsticks to be cleaned, the laser sensor first evaluates the overall situation of the bowls and chopsticks. The feedback light transmittance of the laser sensor is X′. When X′>t, it is determined that the bowls and chopsticks are not very dirty at this time, and only the conventional cleaning mode needs to be used for cleaning, and the water pump etc. do not need to operate at high power. If X′<t, it is determined that the conventional cleaning mode cannot meet the cleaning requirements at this time, and the high-efficiency cleaning mode needs to be entered. In the first stage of the high-speed cleaning mode, only the detergent is used for cleaning, and the laser sensor records the light transmittance X of the cleaning liquid at the beginning of cleaning 11 and the light transmittance X of the cleaning liquid at the end of cleaning 12 . If (X 11 -X 12 ) / X 11 ≤A (the value of A represents the grease decomposition efficiency), it indicates that within a unit time, the grease decomposition efficiency has slowed down, and yeast powder needs to be added to promote grease decomposition. At this time, the yeast powder kit will be opened, and the second stage of the high-speed cleaning mode will be entered, and continuous cleaning will be carried out until the laser sensor measures that the light transmittance X of the cleaning liquid is greater than Z, and it is determined that the cleaning is completed at this time. If (X 21 -X 22 ) / X 21 >A, it is determined that the grease decomposition efficiency is still at a normal level at this time, and there is no need to add yeast powder, and only the detergent can be used for cleaning. Through the above process, the cleaning mode can be dynamically adjusted and the usage amounts of yeast powder and detergent can be adjusted to achieve effective and efficient oil removal.

[0135] It should be noted that the values ​​of the first preset transmittance Z and the second preset transmittance t can be determined based on experiments. First of all, it should be clear that the lower the transmittance, the more stains there are, and the higher the transmittance, the fewer stains there are. The Z value is determined by a feedback value obtained by measuring the clean dishes and chopsticks with a laser sensor. For example, for experimental judgment, when the feedback value is greater than 50%, it can be determined that there are no other stains on the dishes and chopsticks at this time, and the cleaning is completed, and the Z value can be set to 50%. Determination of the t value, for example, experiments have found that when the feedback value is less than 10%, only entering the high-speed cleaning mode can be more effective and efficient cleaning, and at this time the t value can be set to 10%.

[0136] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
