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 dishwashers and washing machines.

[0003] When washing equipment runs a washing program, detergent needs to be added. The detergent produces foam, which helps to wash the clothes. For example, when using a washing machine to wash clothes, detergent needs to be added to the machine to clean the clothes; detergents include laundry liquid, laundry powder, etc.

[0004] During the washing machine washing process, the amount of foam produced by the detergent becomes a crucial factor affecting the washing effect. If there is too little foam, it indicates that the user has used too little detergent, resulting in clothes not being cleaned properly; if there is too much foam, it indicates that the user has used too much detergent, leaving too much detergent residue on the cleaned clothes, which can harm the user's skin.

[0005] Currently, some washing machines use a method of weighing the clothes before adding detergent. However, this method is limited by the varying degrees of soiling on the clothes; clothes of the same weight may require different detergent dosages, resulting in poor cleaning performance or wasted detergent.

[0006] In addition, some washing machines use turbidity sensors to detect the concentration of detergent in the wash water, thereby controlling the precise dispensing of detergent. However, due to factors such as the degree of soiling of the clothes and the obstruction caused by the clothes, there is a relatively high probability of misjudging the detergent concentration, which makes it impossible to accurately obtain the detergent concentration and ultimately affects the washing effect of the clothes.

[0007] In view of this, the present invention is hereby proposed. Summary of the Invention

[0008] The purpose of this invention is to provide a control method for a washing device to achieve precise detergent dispensing, making the detergent dosage more reasonable, ensuring that the clothes to be washed are cleaned effectively, and avoiding detergent residue on the clothes. Another purpose of this invention is to provide a washing device that achieves precise detergent dispensing and avoids detergent waste.

[0009] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0010] A method for controlling a washing device, the washing device including a receiving cavity for accommodating the items to be washed, wherein during the washing process, the projected area S of foam in the receiving cavity is obtained, and if the obtained area S is less than a preset area S0, detergent is added.

[0011] Furthermore, when the obtained area S is less than the preset area S0, the difference △S between the obtained area S and the preset area S0 is calculated and controlled, and the amount of detergent added V is controlled according to the difference △S.

[0012] Furthermore, a database corresponding to the pre-defined difference △S and the supplementary amount V is used to retrieve the corresponding supplementary amount V from the database based on the calculated difference △S;

[0013] Alternatively, a pre-defined calculation model can be used to input the calculated difference ΔS into the calculation model to obtain the supplementary amount V;

[0014] Preferably, the computational model is V = K * ΔS, where K is a constant greater than 1;

[0015] More preferably, different washing processes correspond to different constants K.

[0016] Furthermore, at the start of the washing process, the addition of detergent and premixing are controlled. After premixing is completed, the projected area S of the foam in the receiving cavity is controlled.

[0017] Preferably, the premixing includes: controlling the washing equipment to agitate the washing water in the receiving cavity.

[0018] Furthermore, after premixing, the washing equipment is stopped from stirring, and after a settling time t0, the projected area S of the foam in the containment cavity is obtained;

[0019] Preferably, the settling time t0 is positively correlated with the agitation speed of the washing equipment.

[0020] Furthermore, after the detergent is replenished, if it is detected that another item to be washed has been added to the container, the control will reset the preset area value S0 and re-obtain the projected area S of the foam in the container.

[0021] Furthermore, the washing equipment includes a door for opening and closing the receiving cavity, characterized in that: after the detergent is replenished, if the door is detected to be open, it is determined that the receiving cavity has been filled with items to be washed again;

[0022] And / or, if an increase in weight is detected in the container after detergent has been added, it is determined that the container has been refilled with items to be washed.

[0023] The present invention also provides a control method for a washing device, the washing device including a receiving cavity for accommodating the clothes to be washed, during the rinsing process, obtaining the projected area S of the foam in the receiving cavity, if the obtained area S is greater than a preset area value S0', then controlling to increase the number of rinsing cycles.

[0024] Furthermore, during the rinsing process, the cumulative area S is greater than the preset area value S0' for a duration t. If the duration t is greater than the preset time t0, the number of rinsing cycles is increased.

[0025] Preferably, the number of rinsing cycles is positively correlated with the duration t.

[0026] The present invention also provides a washing device, which is controlled by any of the control methods described above;

[0027] Preferably, the washing equipment includes:

[0028] The image acquisition module is used to obtain the projected area S of the foam within the containment cavity.

[0029] The control module is electrically and / or communicatively connected to the image acquisition module, and is used to control the washing equipment based on the area S obtained by the image acquisition module.

[0030] The present invention also provides a garment processing device, which is controlled by any of the control methods described above.

[0031] Furthermore, the garment processing device includes a washing device and a drying device that can operate independently, and the washing device and the drying device are respectively equipped with a dispensing module for dispensing detergent.

[0032] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0033] In this invention, by obtaining the projected area S of the foam in the receiving cavity, the amount of detergent added in the receiving cavity can be accurately determined. When the obtained area S is less than the preset area S0, it indicates that the amount of detergent added is insufficient. The amount of detergent added is insufficient to clean the items to be washed. The detergent is added in a controlled manner to ensure that the amount of detergent added is sufficient to ensure that the items to be washed can be cleaned.

[0034] The washing equipment of the present invention is controlled by the control method of the present invention, which can reasonably add detergent, resulting in high cleaning efficiency and good cleaning effect, and avoids waste of detergent.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] like Figures 1 to 5 As shown, this invention discloses a control method for a washing device and the washing device itself. "Washing device" refers to a general term for a class of household appliances capable of performing washing programs, such as washing machines and dishwashers.

[0047] The washing device of the present invention includes a receiving cavity for accommodating the items to be washed, and the control method of the washing device includes: during the washing process, obtaining the projected area S of the foam in the receiving cavity; if the obtained area S is less than the preset area S0, then controlling the addition of detergent; otherwise, directly executing the washing program.

[0048] Specifically, such as Figure 1 As shown, the control methods include:

[0049] S1. Begin washing;

[0050] S2, preset area S0; wherein, the preset area S0 is preset according to the amount of clothes to be washed, and the more clothes to be washed, the larger the preset area S0 is.

[0051] S3. Obtain the projected area S of the foam in the receiving cavity; wherein, the projected area S of the foam in the receiving cavity includes: the projected area of ​​the foam on the bottom wall of the receiving cavity, or the projected area of ​​the foam on the liquid surface in the receiving cavity; preferably, the projected area S of the foam in the receiving cavity further includes: the projected area of ​​the foam on the peripheral sidewall of the receiving cavity.

[0052] S4. Determine whether the obtained area S is less than the preset area S0;

[0053] S5. If yes, add more detergent; otherwise, determine that detergent addition is complete.

[0054] S6. After the detergent is added, control the washing equipment to continue washing until the washing is complete;

[0055] S7. After washing, begin rinsing.

[0056] Specifically, step S3 includes:

[0057] The washing equipment was used to collect photos of the cavity before and after detergent was added.

[0058] By comparing photos of the container before and after detergent addition, the area S occupied by foam on the liquid surface in the container is obtained.

[0059] In this invention, by obtaining the projected area S of the foam in the receiving cavity, the amount of detergent added in the receiving cavity can be accurately determined. When the obtained area S is less than the preset area S0, it indicates that the amount of detergent added is insufficient. The amount of detergent added is insufficient to clean the items to be washed. The detergent is added in a controlled manner to ensure that the amount of detergent added is sufficient to ensure that the items to be washed can be cleaned.

[0060] As one embodiment of the present invention, the control method includes:

[0061] When the obtained area S is less than the preset area S0, the difference △S between the obtained area S and the preset area S0 is calculated and controlled, and the amount of detergent V added is controlled according to the difference △S.

[0062] Specifically, such as Figure 2 As shown,

[0063] S1. Begin washing;

[0064] S2, preset area S0;

[0065] S3. Obtain the projected area S of the foam within the containment cavity;

[0066] S4. Determine whether the obtained area S is less than the preset area S0;

[0067] S5. If yes, calculate △S = S0 - S; otherwise, proceed to step S8.

[0068] S6. Obtain the supplementary amount V corresponding to △S;

[0069] S7. Control the addition of detergent, the amount added is V; after the addition is completed, repeat steps S3 to S7.

[0070] S8. Detergent addition complete;

[0071] S9. Control the washing equipment to continue washing until the washing is complete;

[0072] S10. After washing, begin rinsing.

[0073] In this embodiment, by calculating the difference △S between the obtained area S and the preset area S0, the corresponding detergent replenishment amount V can be accurately determined based on the difference △S, so that the detergent replenishment amount V just meets the washing requirements, which not only ensures a good washing effect on the clothes to be washed, but also avoids detergent waste and reduces detergent residue on the clothes to be washed.

[0074] In this embodiment, the amount of detergent added, V, is reasonably controlled based on the difference ΔS, so that the washing equipment can meet the washing requirements with a single addition, reducing the number of times detergent needs to be added and improving washing efficiency.

[0075] As one implementation method of this embodiment, the washing device of the present invention has a database corresponding to the difference ΔS and the supplementary amount V. Based on the calculated difference ΔS, the corresponding supplementary amount V is obtained from the database. The difference ΔS and the supplementary amount V in the database can be obtained through prior experiments or are empirical values.

[0076] Preferably, the difference ΔS is positively correlated with the amount of detergent added, V. The larger the difference ΔS, the less detergent is used. In this case, a larger amount of detergent added, V, is needed to meet the washing requirements and ensure a better washing effect.

[0077] In this embodiment, by setting up a database, a reasonable amount of detergent V can be obtained based on the difference △S. The method of obtaining the amount of detergent is simple, and the amount of detergent V is relatively accurate. This can avoid the waste of detergent while meeting the washing requirements of the clothes to be washed.

[0078] As one implementation method of this embodiment, the washing device of the present invention has a preset calculation model. The calculated difference ΔS is substituted into the calculation model to obtain the supplementary amount V. The calculation model is set before the washing device leaves the factory.

[0079] In this embodiment, by substituting the difference ΔS into the calculation model, the detergent replenishment amount V corresponding to the difference ΔS can be accurately obtained. Moreover, the replenishment amount V is relatively more accurate, ensuring a good cleaning effect on the items to be washed while avoiding detergent waste.

[0080] Preferably, the calculation model in this invention is V = K * ΔS, where K is a constant greater than 1. When the difference ΔS is larger, it indicates that the amount of detergent added is smaller. By controlling K to be a constant greater than 1, the amount of detergent added V is larger, so as to ensure that there is enough detergent and the items to be washed can be cleaned.

[0081] More preferably, the constant K is an empirical value, and it can be corrected during the operation of the washing equipment to ensure that the obtained replenishment amount V is more accurate. The correction method is to adjust the constant K based on the historical amount of laundry and the final amount of detergent added.

[0082] More preferably, different washing processes correspond to different constants K. Specifically, the washing processes include: a normal washing process and an ultra-clean washing process. The normal washing process has lower requirements for the cleanliness of the items being washed (e.g., clothing); the ultra-clean washing process has higher requirements for the cleanliness of the items being washed. The constant K corresponding to the normal washing process is controlled to be smaller than the constant K corresponding to the ultra-clean washing process.

[0083] This control method ensures a higher detergent replenishment amount (V) during the ultra-clean washing process, thereby guaranteeing a higher level of cleaning for the clothes. Furthermore, this method also ensures an appropriate detergent replenishment amount (V) during the regular washing process, meeting washing requirements while avoiding detergent waste.

[0084] As another embodiment of the present invention, the control method of the washing equipment includes:

[0085] At the start of the washing process, control the addition of detergent and premixing;

[0086] After premixing, control the projected area S of the foam in the containment cavity.

[0087] In this embodiment, the detergent is premixed after being added to the washing equipment so that the detergent can fully form foam. Then, the projected area S of the foam in the receiving cavity is obtained so that the amount of detergent added can be more accurately determined by the projected area S of the foam in the receiving cavity.

[0088] The control method of this embodiment avoids inaccurate detection results of the projected area S of the foam in the receiving cavity due to some detergent not dissolving and forming foam, which would lead to excessive detergent being added and wasting detergent. At the same time, it avoids excessive detergent residue on the cleaned items, reducing the waste of water and electricity resources and improving washing efficiency.

[0089] As one implementation of this embodiment, the premix includes:

[0090] The washing equipment is controlled to agitate the washing water in the receiving cavity. Specifically, when the washing equipment is a top-loading washing machine, the agitator of the top-loading washing machine is controlled to rotate to agitate the washing water.

[0091] In this embodiment, by agitating the washing water in the receiving cavity, the detergent can fully form foam, thereby enabling the projected area S of the foam in the receiving cavity to accurately reflect the amount of detergent added, making the detergent addition detection more accurate.

[0092] As one implementation method of this embodiment, such as Figure 3 As shown, the control method for the washing equipment includes:

[0093] S1. Begin washing;

[0094] S2, preset area S0, preset settling time t0;

[0095] S3. Add detergent;

[0096] S4, premixed;

[0097] S5, settling time t0;

[0098] S6. Obtain the projected area S of the foam within the containment cavity;

[0099] S7. Determine whether the obtained area S is less than the preset area S0;

[0100] S8. If yes, control the addition of detergent, and repeat steps S4 to S8 after the addition is completed; otherwise, proceed directly to step S9.

[0101] S9. Detergent addition complete;

[0102] S10. Control the washing equipment to continue washing until the washing is complete;

[0103] S11. After washing, begin rinsing.

[0104] In this embodiment, after premixing, the mixture is left to stand for a period of time so that the foam formed by the detergent stops moving, so as to accurately obtain the projected area of ​​the foam in the receiving cavity, and further accurately measure the amount of detergent added based on the projected area of ​​the foam in the receiving cavity.

[0105] In another implementation of this embodiment, the settling time t0 is positively correlated with the agitation speed of the washing equipment.

[0106] This implementation method allows the settling time t0 to be matched with the agitation speed. When the agitation speed is high, the speed of foam movement is also high. In this case, the settling time t0 is controlled to be relatively long so that the foam can stop moving for a sufficiently long time, which makes it easier to obtain the projected area S of the foam in the containment cavity.

[0107] When the agitation speed is low, the speed of foam movement is also relatively low. At this time, controlling the settling time t0 to be relatively short can both stop the foam movement and obtain the projected area S of the foam in the receiving cavity, and reduce the settling time to improve detection efficiency, thereby improving washing efficiency.

[0108] As one embodiment of the present invention, the control method of the washing equipment includes:

[0109] After the detergent is replenished, if it is detected that another item to be washed has been added to the container, the control will reset the preset area value S0 and re-acquire the projected area S of the foam in the container.

[0110] In this embodiment, if the addition of detergent is detected after the detergent has been replenished, the detergent in the washing equipment will not be sufficient to meet the user's needs for cleaning the items. In this case, the preset area value S0 needs to be readjusted to ensure that the items can be cleaned.

[0111] In one embodiment of this invention, the washing device includes a door for opening and closing the receiving cavity. The control method for the washing device includes:

[0112] If the door is detected to be open after the detergent has been added, it is determined that the container has been filled with new items to be washed.

[0113] In this embodiment, if the door is detected to be open, it indicates that the user may have opened the door during the washing process and added items to be washed.

[0114] Specifically, a position sensor can be installed on the door to determine whether the door is open. In this embodiment, the method for determining whether clothes have been added during the washing process is simple, efficient, and easy to control.

[0115] As another implementation of this embodiment, if an increase in weight is detected in the containment cavity after the detergent is replenished, it is determined that the containment cavity has been filled with more items to be washed.

[0116] Specifically, a weight sensor can be installed inside the receiving cavity to detect whether the weight inside the cavity has increased. This embodiment can accurately determine whether the user has added items to be washed into the receiving cavity during the washing process, and the determination result is accurate and reliable.

[0117] As another embodiment of the present invention, such as Figure 5 As shown, the washing equipment includes a receiving cavity for accommodating the items to be washed. The control method includes:

[0118] During the rinsing process, the projected area S of the foam within the receiving cavity is obtained;

[0119] If the obtained area S is greater than the preset area value S0', the number of rinsing cycles will be increased; where the preset area value S0' is the factory preset value.

[0120] In this embodiment, if the obtained area S is greater than the preset area value S0', it indicates that there is a lot of foam in the washing equipment. At this time, the number of rinsing cycles is increased so that the items to be washed can be rinsed clean and detergent residue is avoided on the items to be washed.

[0121] Conversely, if the obtained area S is less than or equal to the preset area value S0', it indicates that there is less foam in the washing equipment, so there is no need to increase the number of rinses to ensure high rinsing efficiency and save water and electricity resources.

[0122] As one embodiment of the present invention, the control process of the washing equipment includes:

[0123] During the rinsing process, the cumulative area S is greater than the preset area value S0' for a duration t. If the duration t is greater than the preset time t0, the number of rinsing cycles is increased. The preset time t0 is the factory default value.

[0124] In this embodiment, if the duration t is greater than the preset time t0, it indicates that the amount of foam in the containment cavity remains at a relatively high level for a longer period of time. At this time, controlling the increase of rinsing times can effectively avoid detergent residue on the items to be cleaned.

[0125] Conversely, if the duration t is less than or equal to the preset time t0, it indicates that the amount of foam in the containment chamber is only at a relatively high level for a short period of time. In this case, the items to be cleaned can be rinsed clean without increasing the number of rinses, avoiding detergent residue, reducing the waste of water and electricity resources, and improving rinsing efficiency.

[0126] In one embodiment of this invention, the number of rinses is positively correlated with the duration t. In this embodiment, the longer the duration t, the more foam is contained in the cavity. The number of rinses is then increased accordingly to ensure that there is no detergent residue on the item to be cleaned, while the number of rinses is not excessive, thus avoiding waste of water and electricity resources and ensuring high rinsing efficiency.

[0127] This invention also discloses a washing device controlled by the control method of this invention. The washing device controlled by the control method of this invention can rationally dispense detergent, achieving high cleaning efficiency and good cleaning effect, while avoiding detergent waste.

[0128] As one embodiment of the present invention, the washing device includes:

[0129] The image acquisition module is used to obtain the projected area S of the foam within the containment cavity;

[0130] The control module is electrically or communicatively connected to the image acquisition module and is used to control the washing equipment based on the area S obtained by the image acquisition module.

[0131] The image acquisition module can be a camera, which takes pictures of the cavity before and after detergent is added, and sends the picture information to the control module.

[0132] The control module compares and processes the received photos of the container before and after detergent addition to obtain the area S occupied by the foam on the liquid surface in the container.

[0133] In this embodiment, by setting an image acquisition module, the projected area of ​​the foam within the receiving cavity can be accurately obtained, and the amount of detergent to be added can be accurately determined based on the projected area of ​​the foam within the receiving cavity. The control module can determine whether the amount of detergent added is sufficient to meet the cleaning requirements. If not, the control module can reasonably control the amount of detergent to be added based on the amount of detergent added, so that the cleaning effect of the items to be cleaned is better and detergent waste is avoided.

[0134] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
