[0075] Preferably, the additive information includes the type, manufacturer, brand, production date, concentration, ingredients and other relevant parameter information of the additive.
[0076] In this embodiment, the electronic label 401 stores at least the type information of the additives stored in the additive box 4, such as detergent, softener, flavoring agent, disinfectant, etc.
[0077] The electronic label 401 is an NFC tag set on the outer or inner wall of the additive box 4. Of course, the electronic label 401 can also be an RFID tag set on the inner or outer wall of the additive box 4. Since the information interaction effect of NFC is better than that of RFID, moreover, NFC has the advantages of short distance, high bandwidth, and low energy consumption, so it is more suitable for application in washing machines 6.
[0078] In the above solution, the additive information stored inside the electronic label 401 is shipped from the factory. Preferably, the additive information inside the electronic label 401 can be input or changed through the operating panel of the washing machine 6, or can be input through the mobile phone APP or change.
[0079] The electronic label 401 and the additive box 4 can be connected and fixed through the following connection methods, such as integrated injection molding, screw fastening, welding, pasting, snapping, etc.
[0080] Further, as shown in FIG. 1, the washing machine 6 also includes: a first identification module 71, which is provided in the installation cavity or on the box body 1 and is used to read the additive information in electronic label 401 on each additive box 4 in the additive dispenser 3.
[0081] The first identification module 71 is a first RFID reader or a first NFC reader that is installed on the integrated waterway cover on the top of the box body 1 or in the installation cavity corresponding to each additive box 4 in the additive dispenser 3. The additive information in the electronic label 401 on each additive box 4 in the additive dispenser 3 can be read.
[0082] Preferably, as shown in Figure 1, it also includes: a second identification module 72, which is arranged in the spare additive box storage structure 2 or on the integrated waterway cover on the top of the box body 1, and is used to read the additive information in the electronic label 401 on each spare additive box 4 of the spare additive box storage structure 2.
[0083] The second identification module 72 is a second RFID reader or a second NFC reader that is installed on the box body 1 or in the spare additive box storage structure 2 corresponding to each additive box 4 in the spare additive box storage structure 2, the additive information in the electronic label 401 on each spare additive box 4 in the spare additive box storage structure 2 can be read.
[0084] Specifically, the second identification module 72 can identify the type of additive in the additive box 4 placed in each storage position in the spare additive box storage structure 2.
[0085] As shown in Figures 1 to 6, this embodiment also provides a control method with the above-mentioned washing machine 6. As shown in Figure 5, the method includes:
during the process of adding additives, the washing machine 6 sends an alarm prompt to the user that the remaining amount of additives in the additive adding device is insufficient within a set time,
if it is still not detected that the user replaces a new additive box 4, the spare additive suction device 11 is controlled to start, and the additive in the spare additive box 4 is put into the washing machine 6.
[0086] The washing machine control method provided by this embodiment, during the process of adding additives, the washing machine 6 sends an alarm prompt to the user that the remaining amount of additives in the additive adding device is insufficient within a set time: if the user is not detected to replace the new additives, box 4, the spare additive suction device 11 is controlled to start, and the additives in the spare additive box 4 are put into the washing machine 6, effectively avoiding the insufficient amount of additives caused by the user's failure to replace the additive box 4 in time, resulting in laundry deterioration.
[0087] Further preferably, as shown in Figure 6, the method further includes the following steps:
during the process of adding additives;
after the washing machine issues an alarm prompt to the user that the additive balance in the additive delivery device is insufficient;
if it is still not detected that the user has replaced a new additive box, obtain the additive type of the additive box 4 in the additive delivery device that has not been replaced in time;
control the second identification module 72 to start and read the additive information in the Electronic label 401 on each spare additive box 4 in the spare additive box storage structure 2;
determine whether there is an additive box 4 of this type stored in the spare additive box storage structure 2: if so, control the release of the corresponding type of backup additive; if not, continue to alarm.
[0088] The washing machine control method provided by this embodiment uses the electronic label 401 set on the additive box 4 to identify the spare detergent box. When it is detected that the remaining amount of a certain type of additive in the additive delivery device is insufficient, and it is not replaced in the setting time, the electronic label 401 on each additive box 4 in the spare additive box storage structure 2 can be identified through the second identification module 72. When a corresponding type of additive is identified, the additive is controlled to be released to realize the control. The effect of accurately identifying the types of additives in the additive box 4 stored in the spare additive box storage structure 2 and automatically dispensing them not only has a high degree of automation and high dispensing efficiency, but also can effectively avoid the occurrence of mis-dispensing.
