Description

Technical Field

[0001] This invention belongs to the field of mechanical equipment technology, specifically, it relates to a control method for a washing machine and the washing machine itself. Background Technology

[0002] "Washing equipment" refers to a general term for a class of household appliances that can perform washing programs, such as washing machines and washer-dryer combos.

[0003] Existing washing equipment is not only used to wash everyday clothes such as coats and pants, but also to wash shoes, rags and other heavily soiled items. In addition, it can also be used to wash underwear and other intimate clothing.

[0004] The required cleanliness level inside the washing machine drum varies depending on the type of item being washed. For example, when washing underwear, users require a higher level of cleanliness inside the drum to prevent soiling of the underwear.

[0005] Especially with public laundry facilities, where many people are using them, users can only ensure that their own underwear and outerwear are not mixed, but they cannot know the types of clothing washed by users who went before them. This can lead to the risk of cross-contamination during laundry, causing users to be reluctant to use the facilities.

[0006] Although most washing machines nowadays have a drum cleaning function, which automatically cleans the drum at high temperatures when the user selects this function, the level of automation in drum cleaning is low, requiring manual control by the user.

[0007] On the one hand, if users forget to activate the drum cleaning function, there is a risk of contaminating the load to be washed; on the other hand, for some items that do not require a high level of cleanliness inside the drum, activating the drum cleaning function will result in a waste of water and electricity.

[0008] In view of this, the present invention is hereby proposed. Summary of the Invention

[0009] The purpose of this invention is to provide a control method for a washing machine to achieve intelligent control of the opening and closing of the self-cleaning program, so that the washing machine can meet the user's requirements for the cleanliness of the drum while avoiding waste of water and electricity. Another purpose of this invention is to provide a washing machine that prevents the drum from becoming contaminated with the load to be washed and to improve the level of intelligence of the washing machine.

[0010] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0011] This invention discloses a control method for a washing device. The washing device includes a tub for accommodating a load to be washed. Before washing begins, the cleanliness requirements of the load to be washed for the tub are obtained. Based on the obtained cleanliness requirements, the opening and closing of a self-cleaning program for cleaning the tub is controlled.

[0012] Furthermore, controlling the self-cleaning process according to the obtained cleanliness requirements includes:

[0013] The preset cleanliness requirements include high and low cleanliness. The system determines whether the obtained cleanliness requirement is high or low. If it is high cleanliness, the system starts the self-cleaning program; if it is low cleanliness, the system stops the self-cleaning program.

[0014] Furthermore, determining whether the required cleanliness level is high or low includes:

[0015] Pre-set databases for washing load types corresponding to high and low cleanliness levels, obtain the type of the load to be washed, and determine the cleanliness requirement based on the database to which the type of the load to be washed belongs.

[0016] Furthermore, the types of loads to be washed include:

[0017] The database pre-stores images corresponding to each type of load. The image of the load to be washed is obtained, and the image of the load to be washed is matched with the image in the database to obtain the type of the load to be washed.

[0018] Alternatively, obtain the type of load to be washed as input by the user.

[0019] Furthermore, the preset cleanliness requirements include ordinary cleanliness. It is determined whether the obtained cleanliness requirements belong to ordinary cleanliness. If they belong to ordinary cleanliness, the self-cleaning program is controlled to open and close according to the historical operation program of the washing equipment.

[0020] Furthermore, the washing equipment includes a special load washing program, which acquires the historical operating program between the completion of the last self-cleaning program and the current washing program. If the historical operating program includes a special load washing program, the self-cleaning program is activated.

[0021] Preferably, special load washing programs include lingerie washing programs and shoe washing programs.

[0022] Furthermore, a special load type database is preset to obtain the type of load washed in the historical running programs between the completion of the last self-cleaning program and the current wash. If the obtained type belongs to the special load type database, the self-cleaning program is controlled to start.

[0023] Preferably, the special load type database includes: underwear, shoes.

[0024] Furthermore, determining whether the obtained cleanliness requirement falls under the category of ordinary cleanliness includes:

[0025] A database of washing load types corresponding to normal cleanliness is preset. The type of the load to be washed is obtained. If the obtained type of the load to be washed belongs to the database, then the obtained cleanliness is determined to be normal cleanliness.

[0026] Furthermore, the cleanliness requirements of the load to be washed for the inside of the tank include:

[0027] The washing equipment has a module that presets cleanliness requirements, obtains the cleanliness requirement instructions input by the user, and obtains the cleanliness requirements of the load to be washed for the inside of the drum based on the obtained instructions.

[0028] The present invention also provides a washing device, which is controlled by any of the control methods described in the above technical solutions.

[0029] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0030] In this invention, before washing begins, the self-cleaning program is controlled according to the cleanliness requirements of the load to be washed on the drum. When the load to be washed has high cleanliness requirements on the drum, the self-cleaning program can be turned on to avoid contamination of the load by bacteria and viruses in the drum. When the load to be washed has low cleanliness requirements on the drum, the self-cleaning program can be kept off to avoid waste of water and electricity.

[0031] The washing equipment of the present invention rationally controls the opening and closing of the self-cleaning program, and has a high degree of intelligence. It not only avoids the tub from being contaminated by the load to be washed, but also reduces energy waste.

[0090] S10. Determine if the washing is complete;

[0091] S11. If the operation ends, then continue washing; otherwise, control to continue washing and repeat steps S10 to S11.

[0092] In this embodiment, a database of washing load types corresponding to high and low cleanliness is preset. When the type of the load to be washed belongs to the database of washing load types corresponding to high cleanliness, it indicates that the load to be washed has high requirements for the cleanliness of the inside of the drum.

[0093] When the type of the load to be washed belongs to the database of washing load types corresponding to low cleanliness, it indicates that the load to be washed has low requirements for the cleanliness of the inside of the drum, and the judgment result is accurate and reliable.

[0094] In this embodiment, users can adjust the washing load types in the database corresponding to high and low cleanliness levels according to their actual needs, so as to meet the needs of users at different usage periods.

[0095] As one implementation method of this embodiment, the type of load to be washed includes:

[0096] The database pre-stores images corresponding to each type of load;

[0097] Acquire an image of the load to be washed;

[0098] The image of the load to be washed is matched with the images in the database to determine the type of the load to be washed.

[0099] Specifically, such as Figure 4 As shown, the control steps of the washing equipment include:

[0109] S10. Determine if the washing is complete;

[0110] S11. If the operation ends, then continue washing; otherwise, control to continue washing and repeat steps S10 to S11.

[0111] The washing equipment in this embodiment is equipped with an image acquisition module for acquiring images of the load to be washed that has been placed into the tub. Step S3 of this embodiment includes:

[0112] S31. Control the image acquisition module to start;

[0113] S32, Control the acquisition of an image of the load to be washed;

[0114] S32. Upload the acquired images of the load to be washed to the database of images of washing load types corresponding to high and low cleanliness levels.

[0115] In this embodiment, by matching the obtained image of the load to be washed with images in a database of washing load types corresponding to high and low cleanliness, the type of the load to be washed can be accurately determined, and thus the level of cleanliness requirements for the drum can be determined. The determination process is simple, accurate and efficient.

[0116] As another implementation of this embodiment, the type of the load to be washed, as input by the user, is obtained.

[0117] Specifically, users can input the type of load to be washed on the control interface of the washing equipment; the washing equipment can determine the type of the load to be washed based on the input type of the load, and then determine the level of cleanliness requirements for the inside of the drum.

[0118] In this embodiment, the user can input the type of load to be washed according to their own wishes, thereby enabling the self-cleaning program in the washing equipment to be turned on or off according to their own wishes, increasing the user's freedom of use.

[0119] As one embodiment of the present invention, the control method of the washing equipment includes:

[0120] The preset cleanliness requirements include ordinary cleanliness; it is determined whether the obtained cleanliness requirements belong to ordinary cleanliness; if they belong to ordinary cleanliness, the self-cleaning program is controlled to open and close according to the historical operation program of the washing equipment.

[0121] The "normal cleanliness" category refers to loads that do not require a high level of cleanliness inside the drum, such as coats and tablecloths. However, if the drum has previously been used to wash heavily soiled items, it is still necessary to clean the inside of the drum to prevent contamination of the load to be washed and to avoid reducing washing efficiency.

[0122] Specifically, such as Figure 5 As shown, the control steps of the washing equipment include:

[0123] S1, Begin;

[0124] S2, preset high cleanliness, low cleanliness, and normal cleanliness;

[0125] S3. Obtain the cleanliness requirements of the load to be washed for the inside of the tank;

[0126] S4. Determine whether the obtained cleanliness requirement is high cleanliness;

[0127] S5. If yes, start the self-cleaning program and execute steps S8 to S11; otherwise, execute step S6.

[0128] S6. Determine whether the obtained cleanliness requirement belongs to low cleanliness;

[0129] S7. If yes, control the self-cleaning program to turn off, control the start of washing, and execute steps S10 to S11; otherwise, if the obtained cleanliness requirement is ordinary cleanliness, obtain the historical running program, control the self-cleaning program according to the historical running program, then control the start of washing, and execute steps S10 to S11.

[0130] S8. Determine whether self-cleaning is complete;

[0131] S9. If yes, control to start washing and execute steps S10 to S11; otherwise, control to continue the self-cleaning program.

[0132] S10. Determine if the washing is complete;

[0133] S11. If the operation ends, then continue washing; otherwise, control to continue washing and repeat steps S10 to S11.

[0134] In this embodiment, if the obtained cleanliness requirement is ordinary cleanliness, it indicates that the load to be washed does not have high requirements for the cleanliness of the tub. At this time, it is necessary to determine the degree of dirt in the tub based on the historical operation program of the washing equipment, and then determine whether the self-cleaning program needs to be executed based on the degree of dirt in the tub.

[0135] In this embodiment, if the historical operation program shows that the washing equipment has washed heavily soiled items such as shoes and rags, the self-cleaning program is executed to prevent the tub from being contaminated by the load to be washed, thus reducing washing efficiency.

[0136] As one implementation of this embodiment, the washing device includes a special load washing program, which acquires the historical running program between the completion of the last self-cleaning program and the current washing program. If the historical running program includes a special load washing program, the self-cleaning program is controlled to start.

[0137] Special load washing programs include those designed for heavily soiled loads or loads with a high potential for bacteria or viruses. Examples include lingerie washing programs and shoe washing programs.

[0138] In this embodiment, if the historical running program between the completion of the last self-cleaning program and the current washing includes a special load washing program, it indicates that the current level of dirt in the tub is high, and there is a greater risk of bacteria and viruses in the tub. At this time, the self-cleaning program is activated to clean the inside of the tub, so as to avoid contamination of the tub with the load to be washed, and thus avoid harm to the human body.

[0139] If the historical running program between the completion of the last self-cleaning program and the start of the current wash does not include a special load washing program, it indicates that the current level of dirt inside the drum is low. Furthermore, the load to be washed does not require a high level of cleanliness inside the drum. In this case, it is sufficient to meet the washing requirements without activating the self-cleaning program, thus avoiding waste of water and electricity.

[0140] As another implementation of this embodiment, the control method for the washing equipment includes:

[0141] A special load type database is preset to obtain the type of load in the historical running programs between the completion of the last self-cleaning program and the current wash; if the obtained type belongs to the special load type database, the self-cleaning program is started.

[0142] Special load types include those that are heavily soiled or have a high probability of containing bacteria or viruses. For example, special load types include underwear and shoes.

[0143] Specifically, such as Figure 6 As shown, the control steps of the washing equipment include:

[0144] S1, Begin;

[0145] S2, Preset high cleanliness, low cleanliness, and preset special load type databases;

[0146] S3. Obtain the cleanliness requirements of the load to be washed for the inside of the tank;

[0147] S4. Determine whether the obtained cleanliness requirement is high cleanliness;

[0148] S5. If yes, start the self-cleaning program and execute steps S8 to S11; otherwise, execute step S6.

[0149] S6. Determine whether the obtained cleanliness requirement belongs to low cleanliness;

[0150] S7. If yes, control the self-cleaning program to close, control the start of washing, and execute steps S10 to S11; otherwise, the obtained cleanliness requirement is normal cleanliness; obtain the type of load washed in the historical running program between the completion of the last self-cleaning program and the current washing.

[0151] S71. Determine whether the type of the acquired load belongs to a special load type database;

[0152] S72. If yes, control the self-cleaning program to start and execute steps S8 to S11; otherwise, control the washing to start and execute steps S10 to S11.

[0153] S8. Determine whether self-cleaning is complete;

[0154] S9. If yes, control to start washing and execute steps S10 to S11; otherwise, control to continue the self-cleaning program.

[0155] S10. Determine if the washing is complete;

[0156] S11. If the operation ends, then continue washing; otherwise, control to continue washing and repeat steps S10 to S11.

[0157] In this embodiment, if the type of load obtained belongs to the special load type database, it indicates that the washing equipment has cleaned a special type of load. At this time, the self-cleaning program is activated to prevent dirt inside the tub from contaminating the load to be washed and posing a safety hazard to the user.

[0158] Conversely, if the type of load obtained does not belong to the special load type database, it indicates that the washing equipment has not cleaned the special type of load. In this case, there is no need to control the self-cleaning program to start, thus avoiding waste of water and electricity resources.

[0159] In another embodiment of the present invention, determining whether the obtained cleanliness requirement belongs to ordinary cleanliness includes:

[0160] A database of washing load types corresponding to normal cleanliness is preset. The type of the load to be washed is obtained. If the obtained type of the load to be washed belongs to the database, then the obtained cleanliness is determined to be normal cleanliness.

[0161] The database of washing load types corresponding to ordinary cleanliness includes items such as coats, trousers, and curtains.

[0162] In this embodiment, if the obtained type of the load to be washed belongs to the database of washing load types corresponding to the ordinary cleanliness level, it indicates that the cleanliness requirement of the load to be washed for the drum is ordinary cleanliness. Conversely, if the obtained type of the load to be washed does not belong to the database of washing load types corresponding to the ordinary cleanliness level, it indicates that the cleanliness requirement of the load to be washed for the drum is not ordinary cleanliness. The judgment method in this embodiment is simple, accurate, and less prone to error during the judgment process.

[0163] Furthermore, in this embodiment, the user can enter new load types into the database corresponding to the washing load types of ordinary cleanliness according to actual usage needs. Even further, the user can also enter load images, codes, and other information to improve the accuracy of subsequent control.

[0164] In another embodiment of the present invention, obtaining the cleanliness requirements of the load to be washed for the inside of the tank includes:

[0165] The washing equipment has a module that presets cleanliness requirements, obtains the cleanliness requirement instructions input by the user, and obtains the cleanliness requirements of the load to be washed for the inside of the drum based on the obtained instructions.

[0166] Specifically, the modules for input cleanliness requirements of the washing equipment include: high cleanliness module, low cleanliness module, and normal cleanliness module. Users can select the appropriate module according to the actual load to be washed.

[0167] When the user selects the high cleanliness module, the washing equipment receives the high cleanliness requirement command input by the user and controls the self-cleaning program to start, performing self-cleaning on the inside of the tub.

[0168] When the user selects the low cleanliness module, the washing equipment receives the user's low cleanliness requirement command and controls the self-cleaning program to shut down, thus avoiding waste of water and electricity resources.

[0169] When the user selects the normal cleanliness module, the historical operating program of the washing equipment is obtained, and the self-cleaning program is controlled to open and close based on the historical operating program.

[0170] In this embodiment, once the user selects the cleanliness requirement module, the washing equipment prioritizes controlling the self-cleaning program according to the user-selected module, so that the control system of the washing equipment can operate in an orderly manner and there will be no control disorder.

[0171] The present invention also discloses a washing device, which is controlled by any of the control methods described in the above technical solutions.

[0172] The washing equipment of the present invention rationally controls the opening and closing of the self-cleaning program, and has a high degree of intelligence. It not only avoids the tub from being contaminated by the load to be washed, but also reduces energy waste.
