[0068] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0069] Example 1

[0070] like Figure 1 As shown, this embodiment provides a dishwasher control method. After the dishwasher is started, it can obtain the weight of the oil stains on the dishes to be cleaned and adjust the dishwashing cleaning parameters based on the weight of the oil stains. Compared with the existing technology that selects cleaning parameters based on the weight of the dishes to be cleaned, this embodiment adjusts the cleaning parameters based on the weight of the oil stains. This can better match the degree of oil stains on the dishes with the cleaning program, thereby reducing energy waste while ensuring cleaning results, and improving the user experience.

[0071] like Figure 2As shown, in order to obtain the weight of the oil stains on the tableware to be cleaned, the weight of the tableware to be cleaned and the theoretical weight of the tableware to be cleaned in a clean state are weighed, and the difference between the two is calculated, that is, the weight of the oil stains on the tableware.

[0072] The weight of the tableware to be cleaned can be measured by a pressure sensor or a weighing sensor, and the accuracy of the weight of the tableware to be cleaned is high. Alternatively, a container for accommodating tableware is arranged in the dishwasher, and the container is a shelf. The weight of the shelf is stored in the dishwasher in advance. After the tableware to be cleaned is put in, the total weight of the shelf and the tableware to be cleaned is measured by the pressure sensor or the weighing sensor, and the total weight is subtracted from the stored weight of the shelf, so that the weight of the tableware to be cleaned is obtained.

[0073] The operability of obtaining the theoretical weight of the tableware to be cleaned in a clean state by actual measurement is poor. Therefore, as shown in the embodiment, Figure 3 The dishwasher can store the individual weight of each type of tableware in the dishwasher. Before the dishwasher works, the user can input the type and quantity of the tableware to be cleaned through the control panel on the dishwasher. The product of the quantity of each type of tableware input by the user and the corresponding individual weight is calculated by summation, so that the theoretical weight of the tableware to be cleaned in a clean state is obtained, and the weight of the oil stains is obtained.

[0074] For example, the tableware to be cleaned includes bowls and plates, and the dishwasher stores the weight M of each bowl and the weight m of each plate. After the user puts the tableware to be cleaned into the dishwasher, the number of bowls a and the number of plates b are input through the control panel. The theoretical weight of the tableware to be cleaned in a clean state can be obtained as Ma+mb.

[0075] Alternatively, in order to simplify the operation of the user, the user can directly input the number of sets of tableware. Each set of tableware includes a plurality of types of tableware, and each type of tableware is one. The dishwasher stores the weight of each set of tableware in a clean state. When the user inputs the number of sets of tableware, the product of the number of sets of tableware and the weight of each set of tableware in a clean state is calculated, so that the theoretical weight of the tableware to be cleaned in a clean state is obtained.

[0076] After the tableware to be cleaned is weighed and the theoretical weight is calculated, the weight of the oil stains can be obtained. According to the weight of the oil stains, the cleaning parameters can be adjusted to ensure the cleaning effect and reduce energy waste, which is conducive to improving the user experience.

[0077] Alternatively, the cleaning parameters can be the amount of water, the washing time, the drying time and / or the cleaning water pressure, so that the tableware is cleaned and the amount of water, time and electric energy are reasonably used.

[0078] Exemplarily, a corresponding table of oil stain weight and cleaning parameter can be stored in the dishwasher, and according to the calculated oil stain weight, the table is looked up to obtain the cleaning parameters, which is beneficial to save program operation time.

[0079] Exemplarily, the control program in the dishwasher can divide the oil stain weight into a plurality of reference ranges, and each reference range corresponds to a set of cleaning parameters, wherein the set of cleaning parameters includes water quantity, washing time, drying time and / or cleaning water pressure. When the oil stain weight of the tableware to be cleaned is calculated, the reference range in which the oil stain weight is located is determined, so that the cleaning parameter corresponding to the reference range is selected for cleaning.

[0080] When the oil stain weight is large, the tableware is difficult to clean, and correspondingly, the water quantity is large, the washing time and the drying time are long, and the cleaning water pressure is large; when the oil stain weight is small, the tableware is easy to clean, and correspondingly, the water quantity is small, the washing time and the drying time are short, and the cleaning water pressure is small.

[0081] Embodiment Two

[0082] The embodiment provides a control method of a dishwasher, which is different from the embodiment one in that a method for obtaining a theoretical weight of tableware to be cleaned is different.

[0083] Specifically, as shown in the figure, Figure 4 image information of the tableware to be cleaned is obtained, and by analyzing the image information, the types of the tableware and the number of each type of tableware in the tableware to be cleaned can be identified. According to the identified types of the tableware, the single weight of each type of tableware pre-stored in the dishwasher can be obtained. By calculating the product of the single weight and the number of the tableware, the total weight of each type of tableware can be obtained, and by calculating the sum of the weights of the plurality of types of tableware, the theoretical weight of the tableware to be cleaned in the cleaning state can be obtained.

[0084] The method for obtaining the theoretical weight in the embodiment does not require the user to input the tableware information, has high automation and intelligence, and can improve the user experience.

[0085] It is worth noting that the identification of the types and the number of the tableware by analyzing the image information can be achieved by image recognition technology. The embodiment can use any image recognition technology in the prior art to identify the number and the types of the tableware, and the specific principle and control method of image recognition are not described in detail in the embodiment.

[0086] Embodiment Three

[0087] As shown in the figure, Figure 5 The embodiment provides a control method of a dishwasher, which is different from the embodiment one in that a method for obtaining a theoretical weight of tableware to be cleaned is different.

[0088] After washing the dishes, dry them;

[0089] Obtain the difference between the weight of the tableware after drying and the theoretical weight. If the difference is greater than a specified difference, repeat the cleaning and drying process until the difference is less than the specified difference.

[0090] Specifically, after washing and drying the dishes, the weight of the dried dishes is obtained and compared with the theoretical weight. If the difference between the two is no greater than a preset specified difference, the dishes are clean. If the difference between the two is greater than the preset specified difference, grease still remains on the dishes and the dishes are not clean. The washing and drying process needs to be repeated until the difference is less than the specified difference.

[0091] Optionally, the designated difference value can be set based on actual needs. For example, the designated difference value can be zero. Preferably, because the theoretical weight of the dishes to be washed in a clean state is a calculated value with a certain error, and to compensate for this error and require multiple repetitions of the washing and drying processes, the designated difference value is non-zero and is not less than the calculated error of the theoretical weight.

[0092] Optionally, when the weight of the dishes after drying is compared with the theoretical weight and a further wash and drying is required, the weight of the oil stain is updated and the washing parameters are readjusted based on the updated weight of the oil stain, where the updated weight of the oil stain is the difference between the weight of the dried dishes and the theoretical weight. By updating the weight of the oil stain, it is possible to avoid excessively long re-washing and drying times, thereby avoiding energy waste.

[0093] Example 4

[0094] like Figure 6 As shown, this embodiment provides a method for controlling a dishwasher, which differs from the above embodiment in that it further includes:

[0095] The weight of the tableware to be washed is obtained, and the tableware cleaning parameters are adjusted according to the weight of the tableware to be washed and the weight of the oil stains on the tableware.

[0096] The cleaning parameters are not only related to the weight of the oil stains, but also directly related to the number of dishes. In order to better match the cleaning parameters with the actual situation of the dishes, the weight of the dishes to be cleaned also needs to be considered when adjusting the cleaning parameters.

[0097] Specifically, if Figure 7 As shown, the basic parameters for cleaning are obtained according to the weight of the tableware to be cleaned, and then the weight of the oil stains is obtained. According to the weight of the oil stains, the adjustment value of the cleaning parameter is obtained. The cleaning parameter is the sum of the basic parameter and the adjustment value.

[0098] In this embodiment, the basic parameter obtained according to the weight of the dishes to be cleaned corresponds to the base number, so that the preselected cleaning parameters required for cleaning are obtained according to the number of dishes. For example, when the weight of the dishes to be cleaned is heavy, the number of dishes to be cleaned is large, and at this time, the water required is large, the cleaning and drying time is long, and the cleaning water pressure is increased; when the weight of the dishes to be cleaned is light, the number of dishes to be cleaned is large, and at this time, the water required is small, the cleaning and drying time is short, and the cleaning water pressure is small.

[0099] In the case where the types of dishes to be cleaned and the number of each type are unchanged, if the oil stain conditions are different, the matched cleaning parameters will also be different. Therefore, on the basis of obtaining the basic parameter, the adjustment value of the cleaning parameter can be obtained according to the weight of the oil stain.

[0100] For example, when the oil stain weight is small, the oil stain on the dishes is less, and it is easier to clean, so the absolute value of the adjustment value is small, the final water consumption is small, the cleaning and drying time is short, and the cleaning water pressure is small. The adjustment amount can be positive or negative. When the oil stain weight is large, the oil stain on the dishes is more, and it is more difficult to clean, so the adjustment value is increased, the final water consumption is large, the cleaning and drying time is long, and the cleaning water pressure is increased. Preferably, when the oil stain weight is large, the adjustment value is positive to obtain better cleaning effect.

[0101] In other embodiments, the basic parameter can also be obtained according to the theoretical weight of the dishes to be cleaned in the cleaning state, which can improve the accuracy of the basic parameter.
