[0010] In the preferred embodiment of the dishwasher control method described above, the tableware information includes tableware material, and the target washing parameters include target washing temperature. The step of "determining the tableware information of each tableware to be washed based on the RFID tag of each tableware to be washed" specifically includes: determining the tableware material of each tableware to be washed based on the RFID tag of each tableware to be washed. The step of "determining the target washing parameters based on the tableware information of all tableware to be washed" specifically includes: determining whether the tableware materials of all tableware to be washed belong to the same material type; if the tableware materials of all tableware to be washed belong to the same material type, then obtaining the safe washing temperature corresponding to that material type and determining that safe washing temperature as the target washing temperature; if the tableware materials of all tableware to be washed do not belong to the same material type, then obtaining the safe washing temperature corresponding to each material type, comparing multiple safe washing temperatures, and determining the smallest safe washing temperature as the target washing temperature.

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings, in which:

[0020] Figure 1 This is a flowchart of the main steps of the dishwasher control method of the present invention;

[0021] Figure 2 This is a flowchart of a first embodiment of the dishwasher control method of the present invention;

[0022] Figure 3 This is a flowchart of the "execution of a special washing mode" of the dishwasher control method of the present invention. Detailed Implementation

[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the term "setup" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through other components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] As pointed out in the background art, the washing modes of existing dishwashers cannot be matched with the dishes to be washed in real time, which makes the operation cumbersome for users and causes damage to the dishes during the washing process.

[0026] The dishwasher control method of the present invention selectively executes a normal mode or a special washing mode based on the total amount of dishes to be washed and special quantities of dishes to be washed, so that the final washing parameters are matched with the dishes to be washed at that time. This allows for faster washing while ensuring that the dishes are not damaged, saving washing time and improving washing efficiency. In addition, this control method does not require the user to manually select the washing program corresponding to the dishes to be washed, making it convenient to operate and more user-friendly, effectively improving the user experience.

[0027] Specifically, the dishwasher of the present invention is equipped with an RFID identification device for identifying RFID tags on tableware.

[0028] Preferably, the RFID identification device is installed on the dishwasher door. After the door is opened, the RFID identification device can identify the RFID tags on the dishes placed inside the dishwasher. Installing the RFID identification device on the dishwasher door saves space, and when the door is opened, the RFID identification device is positioned towards the dish placement path. During the process of placing the dishes into the dishwasher drum, the RFID identification device can scan the RFID tags on the dishes, thereby obtaining the dish information carried by the RFID tags.

[0029] The dishwasher of the present invention also includes a controller configured to perform the control method of the dishwasher of the present invention.

[0030] Specifically, please refer to Figure 1 The dishwasher control method of the present invention includes the following steps:

[0031] S1: Get the total number of all dishes to be washed, denoted as the total number to be washed.

[0032] For example, after all the dishes to be washed are placed in the dishwashing area, the user can manually enter the total number of dishes to be washed via the touchscreen, thereby obtaining the value entered by the user as the total number of dishes to be washed.

[0033] For example, an image acquisition device is provided above the inner tub of the dishwasher, which can acquire images of the tableware in the inner tub and determine the total number of tableware to be washed by the images acquired by the image acquisition device.

[0034] S2: Obtain the number of dishes to be washed with RFID tags, and record it as the special quantity to be washed.

[0035] Specifically, the RFID identification device performs a count each time it identifies an RFID tag, and the total count is the number of special items to be washed.

[0036] S3: Selectively execute the normal washing mode or the special washing mode based on the total amount to be washed and the special quantity to be washed.

[0037] The normal washing mode washes according to the default washing parameters; the special washing mode automatically selects the corresponding target washing parameters based on the RFID tag.

[0038] The dishwasher control method of the present invention selectively executes a normal mode or a special washing mode based on the total amount of dishes to be washed and special quantities of dishes to be washed, so that the final washing parameters are matched with the dishes to be washed at that time. This allows for faster washing while ensuring that the dishes are not damaged, saving washing time and improving washing efficiency. In addition, this control method does not require the user to manually select the washing program corresponding to the dishes to be washed, making it convenient to operate and more user-friendly, effectively improving the user experience.

[0039] Preferably, the default washing parameters include standard washing water pressure and standard washing temperature, with the standard washing water pressure not exceeding 60,000 Pa and the standard washing temperature not exceeding 70°C. Ensuring that the default washing parameters have a water pressure not exceeding 60,000 Pa and a washing temperature not exceeding 70°C is suitable for tableware of all materials, and that this water pressure will not damage the tableware, thus ensuring the tableware remains intact and preventing damage.

[0040] It should be noted that this invention does not impose any limitations on the specific execution steps of step S3. In practical applications, those skilled in the art can set the specific execution steps of step S3 according to actual needs. For example, the difference between the total amount to be washed and the special amount to be washed can be calculated, and a normal washing mode or a special washing mode can be selectively executed based on the difference; or the total amount to be washed and the special amount to be washed can be directly compared, and a normal washing mode or a special washing mode can be selectively executed based on the comparison result, and so on. Adjustments and changes to the specific execution steps of step S3 do not deviate from the basic principles of this invention and should all be limited to the protection scope of this invention.

[0041] In a preferred embodiment, please refer to Figure 2 Step S3, "Selectively execute a normal washing mode or a special washing mode based on the total amount to be washed and the special quantity to be washed," specifically includes:

[0042] S31: Determine whether the special quantity to be washed is equal to the total quantity to be washed.

[0043] The special quantity to be washed is compared with the total quantity to be washed to determine whether the special quantity to be washed is equal to the total quantity to be washed, so that the normal washing mode or the special washing mode can be selectively executed based on the comparison result.

[0044] Specifically, the step of "selectively executing a normal washing mode or a special washing mode based on the comparison results" includes: if the special washing quantity is equal to the total washing quantity, then step S32 is executed; if the special washing quantity is not equal to the total washing quantity, then step S33 is executed.

[0045] S32: Execute a special washing mode;

[0046] When the judgment result is "yes", the special quantity to be washed is equal to the total quantity to be washed, indicating that the tableware to be washed are all tableware with RFID tags. At this time, a special washing mode is executed. Based on the tableware information provided in the RFID tags, the washing parameters that best match the tableware to be washed are determined and washed according to the washing parameters. While ensuring that the tableware is not damaged, the washing speed is improved and the washing effect is guaranteed.

[0047] S33: Perform normal washing mode.

[0048] When the judgment result is "no", the number of special dishes to be washed is less than the total number of dishes to be washed. This means that there are still dishes without RFID tags among the dishes to be washed. Since the nature of all dishes to be washed cannot be determined by RFID tags, the normal washing mode is executed and the dishes are washed directly according to the default washing parameters to avoid damaging the dishes.

[0049] Preferably, please refer to Figure 3 The steps in step S32, "Execute a special washing mode", specifically include:

[0050] S321: Determine the tableware information of each tableware to be washed based on the RFID tag of each tableware to be washed.

[0051] S322: Determine the target washing parameters based on the tableware information of all tableware to be washed.

[0052] After determining the tableware information for each piece of tableware to be washed, the target washing parameters are determined based on all the tableware information.

[0053] S323: Wash according to the target washing parameters.

[0054] After determining the target washing parameters, wash according to the target washing parameters.

[0055] The above setting method identifies the target washing parameters that match the current tableware by identifying the information on the RFID tag of each tableware to be washed, and then washes the tableware according to the target washing parameters. This ensures that the tableware is not damaged during the washing process and can be washed quickly, effectively improving washing efficiency.

[0056] It should be noted that this invention does not impose any limitations on the specific steps of step S322. In practical applications, those skilled in the art can set the specific steps of step S322 according to actual needs, as long as the target washing parameters can be determined. Adjustments and changes to the specific execution steps of step S322 do not deviate from the basic principles of this invention and should be limited to the protection scope of this invention.

[0060] S3221: Determine whether all the tableware to be washed is made of the same material type.

[0061] Determine whether all the tableware to be washed is made of the same material type in order to quickly determine the target washing parameters.

[0062] S3222: If all the tableware to be washed is made of the same material, obtain the safe washing water pressure corresponding to that material type, and set the safe washing water pressure as the target washing water pressure, then proceed to step S3231.

[0063] When all the tableware to be washed is made of the same material, obtain the safe washing water pressure corresponding to that material type, and determine that safe washing water pressure as the target washing water pressure so that subsequent washing can be carried out according to the target washing water pressure.

[0064] Specifically, the controller stores a "Material Type and Target Washing Water Pressure Comparison Table". After the material type is determined, the target washing water pressure corresponding to the material type is determined according to the "Material Type and Target Washing Water Pressure Comparison Table".

[0065] S3223: If all the tableware to be washed is made of different materials, obtain the safe washing water pressure corresponding to each material type.

[0066] If all the tableware to be washed is not made of the same material, the safe washing water pressure corresponding to each material type is obtained so as to determine the target washing water pressure based on multiple safe washing water pressures.

[0067] S3224: Compare multiple safe washing water pressures and determine the lowest safe washing water pressure as the target washing water pressure.

[0068] The minimum safe washing water pressure among multiple safe washing water pressures is selected as the target washing water pressure to ensure that all dishes are not damaged during washing, thereby improving the user experience.

[0069] S3231: Wash according to the target washing water pressure.

[0070] Once the target washing water pressure is determined, washing is carried out according to the target washing water pressure.

[0071] In one embodiment, the tableware information includes the tableware material, and the target washing parameters include the target washing temperature; step S32, "execute a special washing mode," specifically includes:

[0072] S3211: Determine the material of each piece of tableware to be washed based on the RFID tag of each piece of tableware to be washed.

[0073] RFID identification devices identify RFID tags to obtain and determine the material of each piece of tableware to be washed.

[0074] S3221: Determine whether all the tableware to be washed is made of the same material type.

[0075] Determine whether all the tableware to be washed is made of the same material type in order to quickly determine the target washing parameters.

[0076] S3222: If all the tableware to be washed is made of the same material, obtain the safe washing temperature corresponding to that material type, and set the safe washing temperature as the target washing temperature, then proceed to step S3231.

[0077] When all the tableware to be washed is made of the same material, obtain the safe washing temperature corresponding to that material type, and set that safe washing temperature as the target washing temperature so that subsequent washing can be carried out according to that target washing temperature.

[0078] Specifically, the controller stores a "Material Type and Target Washing Temperature Comparison Table". After the material type is determined, the target washing temperature corresponding to the material type is determined according to the "Material Type and Target Washing Temperature Comparison Table".

[0079] S3223: If all the tableware to be washed is made of different materials, obtain the safe washing temperature for each material type.

[0080] If all the tableware to be washed is not made of the same material, the safe washing temperature corresponding to each material type is obtained so that the target washing temperature can be determined based on multiple safe washing temperatures.

[0081] S3224: Compare multiple safe washing temperatures and determine the lowest safe washing temperature as the target washing temperature, then proceed to step S3231.

[0082] The lowest safe washing temperature among multiple safe washing temperatures is selected as the target washing temperature to ensure that all tableware is not damaged during washing, thus improving the user experience.

[0083] S3231: Wash according to the target washing temperature.

[0084] Once the target washing temperature is determined, the washing process is carried out according to the target washing temperature.

[0085] In one embodiment, the tableware information includes tableware size, the target washing parameters include target washing water volume, and step S32, "execute a special washing mode," specifically includes:

[0086] S3211: Determine the size of each piece of tableware to be washed based on the RFID tag of each piece of tableware to be washed.

[0087] RFID identification devices identify RFID tags to obtain and determine the size of each piece of tableware to be washed.

[0088] S3221: Determine the preset water consumption for each piece of tableware to be washed based on the size of each piece of tableware.

[0089] After determining the size of the tableware, the preset water volume for each piece of tableware to be washed is determined based on the size of the tableware.

[0090] Specifically, the controller stores a "Table of Tableware Size and Preset Water Consumption". After determining the tableware size, the corresponding preset water consumption is determined according to the "Table of Tableware Size and Preset Water Consumption".

[0091] S3222: Add up the preset water usage of all dishes to be washed to get the preset total water usage.

[0092] S3223: Compare the preset total water consumption with the minimum washing water consumption.

[0093] The preset total water consumption is compared with the minimum washing water consumption to determine whether the preset total water consumption is greater than the minimum washing water consumption.

[0094] S3224: If the preset total water consumption is greater than the minimum washing water consumption, then the preset total water consumption is set as the target washing water consumption, and then step S3231 is executed.

[0095] When the preset total water consumption is greater than the minimum washing water consumption, the preset total water consumption is set as the target washing water consumption so that all dishes can be washed clean.

[0096] S3225: If the preset total water consumption is not greater than the minimum washing water consumption, then the minimum washing water consumption is set as the target washing water consumption, and then step S3231 is executed.

[0097] When the total preset water consumption is no greater than the minimum washing water consumption, the minimum washing water consumption is set as the target washing water consumption to ensure smooth washing of dishes and guarantee washing results.

[0098] S3231: Wash according to the target washing water volume.

[0099] It should be noted that the minimum washing water volume is the amount of water required to wash one piece of tableware and clean it, as determined through testing.
