Description

Technical Field

[0001] This application belongs to the field of washing machine technology, and in particular relates to a washing machine and its control method, control device and storage medium. Background Technology

[0002] The washing machine's water inlet box has three chambers: a pre-wash chamber, a main wash chamber, and a softening chamber. These chambers contain disinfectant, laundry detergent, and fabric softener, respectively. During the pre-wash cycle, water enters the pre-wash chamber, flushing the disinfectant into the drum. During the main wash cycle, water enters the main wash chamber, flushing the laundry detergent into the drum. During the final rinse cycle, water enters the softening chamber, flushing the fabric softener into the drum.

[0003] The softening chamber is usually located between the main wash chamber and the pre-wash chamber. Users can easily remember that the middle position is where the softener is placed, but they can easily confuse the placement of laundry detergent and disinfectant. Users may mistakenly put the laundry detergent into the pre-wash chamber, resulting in no laundry detergent acting on the clothes in the drum during the main wash, thus failing to clean the clothes properly.

[0044] Figure 8 A structural block diagram of a washing machine provided in an embodiment of this application. Detailed Implementation

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0046] A type of drum washing machine is designed to mimic the principle of beating clothes with a stick. It consists of a stainless steel inner drum, a mechanical program controller, an outer shell protected by phosphating, electrophoresis, and spraying, and several heavy cement blocks to balance the huge centrifugal force generated when the drum rotates. The repeated motion, combined with the action of detergent and water, cleans the clothes.

[0047] With the continuous development of science and technology, washing machines are constantly being updated and iterated to meet the ever-growing new demands of users. New-generation washing machines not only require laundry detergent to clean clothes, but also fabric softener to soften and care for them, reducing wrinkles after washing. Furthermore, in scenarios with high viral loads, laundry detergent alone is insufficient to eliminate these viruses. Therefore, new-generation washing machines typically also require disinfectant for pre-treatment of clothes before washing.

[0048] For example, a washing machine includes a drum and a water inlet tray. The drum carries clothes and rotates them to clean them by tumbling them and using detergent. The water inlet tray is positioned corresponding to the drum and includes a pre-wash chamber, a main wash chamber, and a softening chamber for holding disinfectant, detergent, and fabric softener, respectively. The softening chamber is located between the pre-wash chamber and the main wash chamber.

[0049] The washing machine also includes a pre-wash hose, a pre-wash valve, a main wash hose, and a main wash valve. The pre-wash hose faces the pre-wash chamber to deliver water to it, thus flushing the liquid inside the pre-wash chamber into the drum. The pre-wash valve is used to open or close the pre-wash hose, controlling whether the pre-wash chamber is rinsed. The main wash hose faces the main wash chamber to deliver water to it, thus flushing the liquid inside the main wash chamber into the drum.

[0050] However, since the fabric softener is usually placed between the main wash chamber and the pre-wash chamber, users can easily remember that the middle position is where the fabric softener is placed, but they can easily confuse the placement of laundry detergent and disinfectant. Users may mistakenly put the laundry detergent into the pre-wash chamber, resulting in no laundry detergent acting on the clothes in the drum during the main wash stage, thus failing to clean the clothes properly.

[0051] To reduce the occurrence of the above situations, embodiments of this application provide a washing machine and its control method, control device and storage medium, which will be described below in conjunction with the accompanying drawings.

[0052] For example, please refer to Figure 1 As shown, Figure 1 This is a first flowchart illustrating a control method for a washing machine provided in an embodiment of this application. An embodiment of this application provides a control method for a washing machine, including:

[0053] 101. During the main wash stage, control the pre-wash valve to open and connect the pre-wash pipe to flush the liquid in the pre-wash chamber into the drum.

[0054] During the main wash stage, laundry detergent needs to be added, so the main wash valve needs to be opened to open the main wash hose, allowing water to enter the main wash chamber and flush the laundry detergent into the drum.

[0055] However, if users mistakenly put the laundry detergent into the pre-wash chamber due to confusion between the main wash chamber and the pre-wash chamber, and then open the main wash valve during the main wash stage to rinse the main wash chamber, the laundry detergent cannot be added into the drum. As a result, the laundry detergent cannot act on the clothes, or rather, the laundry detergent and disinfectant cannot perform their respective functions effectively, leading to clothes that are not cleaned properly.

[0056] To reduce the occurrence of the above situation, this application embodiment adds a rinsing process for the pre-wash chamber during the main wash stage. This process can flush the laundry detergent that has been mistakenly placed in the pre-wash chamber into the drum, thereby allowing the laundry detergent to play its role during the main wash stage and improving the cleanliness of the clothes.

[0057] For example, the water intake sequence can be set during the main wash stage, that is, water enters from the pre-wash chamber first during the main wash stage, so that the laundry detergent can be put into the drum and achieve the cleaning effect on the clothes regardless of whether the user puts the laundry detergent in the wrong place.

[0058] 102. Control the main wash valve to open and connect the main wash pipe to flush the liquid in the main wash chamber into the drum.

[0059] During the main wash stage, regardless of whether the laundry detergent is mistakenly placed in the pre-wash chamber, the main wash valve can be opened and the main wash pipe can be connected, thereby allowing water to enter and flush the liquid in the main wash chamber into the drum, thus increasing the probability of laundry detergent entering the drum and improving the probability of clothes being cleaned.

[0060] In the washing machine control method provided in this application embodiment, by adding a rinsing process to the pre-wash chamber during the main wash stage, the washing liquid can be added into the drum even if the user mistakenly puts the washing liquid into the pre-wash chamber, thereby increasing the probability of the washing liquid acting on the clothes and improving the cleaning effect on the clothes; in addition, it can also increase the washing machine's tolerance for incorrect placement of washing liquid, making the washing machine more intelligent and improving the user experience.

[0061] In order to reduce costs and increase efficiency in washing machines, the relevant technology replaces the original pre-wash pipe and pre-wash valve, main wash pipe and main wash valve, and softening pipe and softening valve corresponding to the pre-wash chamber, main wash chamber, and softening chamber with a pre-wash pipe and pre-wash valve and a main wash pipe and main wash valve. Water enters through the pre-wash pipe and main wash pipe simultaneously, and flushes the water into the softening chamber between the main wash chamber and the pre-wash chamber, thereby saving softening pipes and softening valves and reducing the manufacturing cost of the washing machine.

[0062] In practice, the pre-wash valve and main wash valve may switch too frequently, and the water in the pre-wash pipe may not drain completely, resulting in a brief flushing in the softening chamber. This causes the softener to be lost too early and fail to provide a softening effect during the rinsing stage.

[0063] To reduce the occurrence of the above-mentioned situations, the control logic of the washing machine has been further improved in this application embodiment. Please refer to... Figure 2 As shown, Figure 2 This is a second flowchart illustrating the control method for a washing machine provided in an embodiment of this application. This application also provides a control method for a washing machine, including:

[0064] 201. During the main wash stage, control the pre-wash valve to open and connect the pre-wash pipe to flush the liquid in the pre-wash chamber into the drum.

[0065] During the main wash stage, laundry detergent needs to be added, so the main wash valve needs to be opened to open the main wash hose, allowing water to enter the main wash chamber and flush the laundry detergent into the drum.

[0066] However, if users mistakenly put the laundry detergent into the pre-wash chamber due to confusion between the main wash chamber and the pre-wash chamber, and then open the main wash valve during the main wash stage to rinse the main wash chamber, the laundry detergent cannot be added into the drum. As a result, the laundry detergent cannot act on the clothes, or rather, the laundry detergent and disinfectant cannot perform their respective functions effectively, leading to clothes that are not cleaned properly.

[0067] To reduce the occurrence of the above situation, this application embodiment adds a rinsing process for the pre-wash chamber during the main wash stage. This process can flush the laundry detergent that has been mistakenly placed in the pre-wash chamber into the drum, thereby allowing the laundry detergent to play its role during the main wash stage and improving the cleanliness of the clothes.

[0068] For example, the water intake sequence can be set during the main wash stage, that is, water enters from the pre-wash chamber first during the main wash stage, so that the laundry detergent can be put into the drum and achieve the cleaning effect on the clothes regardless of whether the user puts the laundry detergent in the wrong place.

[0069] 202. After the pre-wash valve has been closed for a preset time, control the main wash valve to open and connect the main wash pipe to flush the liquid in the main wash chamber into the drum.

[0070] During the main wash stage, regardless of whether the laundry detergent is mistakenly placed in the pre-wash chamber, the main wash valve can be opened and the main wash pipe can be connected, thereby allowing water to enter and flush the liquid in the main wash chamber into the drum, thus increasing the probability of laundry detergent entering the drum and improving the probability of clothes being cleaned.

[0071] If the main wash valve is opened immediately after the pre-wash valve is closed, the water in the pre-wash tube will not have drained completely, and the water in the main wash tube will counteract it. This will cause the fabric softener in the softening chamber to be lost too early, resulting in waste of the fabric softener and preventing it from softening the clothes.

[0072] Therefore, in order to reduce the occurrence of this situation, in this embodiment of the application, after the pre-wash valve is closed, the main wash valve is opened after a preset time interval, such as 5 seconds, to drain the water in the pre-wash tube, thereby reducing the phenomenon of premature loss of fabric softener caused by counter-current in the fabric softener chamber.

[0073] In the washing machine control method provided in this application embodiment, by adding a flushing motion to the pre-wash chamber during the main wash stage, the washing liquid can be dispensed into the drum even if the user mistakenly puts it into the pre-wash chamber. This increases the probability of the washing liquid acting on the clothes, thereby improving the cleaning effect. Furthermore, it increases the washing machine's tolerance for incorrect liquid placement, making the washing machine more intelligent and enhancing the user experience. Opening the main wash valve after the pre-wash valve has been closed for a preset time reduces the phenomenon of backwashing within the fabric softener chamber, thus reducing the problem of premature fabric softener loss and improving the treatment effect on clothes.

[0074] Please see Figure 3 As shown, Figure 3 This is a third flowchart illustrating the control method for a washing machine provided in an embodiment of this application. An embodiment of this application also provides a control method for a washing machine, including:

[0075] 301. During the pre-washing stage, control the pre-washing valve to open and connect the pre-washing pipe to flush the liquid in the pre-washing chamber into the drum.

[0076] The purpose of the pre-washing stage is mainly to disinfect clothes with disinfectant in advance to remove viruses, bacteria and other substances that may threaten human health.

[0077] During the pre-wash stage, the pre-wash valve is controlled to open and close according to a set on / off ratio. For example, the pre-wash valve can be controlled to open for 5 seconds, close for 5 seconds, and continue this on / off cycle for 30 seconds. This allows liquids such as disinfectant in the pre-wash chamber to be flushed into the drum, effectively rinsing the pre-wash chamber. This prevents disinfectant from adhering to the pre-wash chamber, reducing the problem of disinfectant contamination of clothes, improving the utilization rate of disinfectant, and reducing material waste.

[0078] 302. During the main wash stage, the pre-wash valve is controlled to operate at a second preset on / off ratio and continue for a second duration to flush the liquid in the pre-wash chamber into the drum.

[0079] During the main wash stage, laundry detergent needs to be added, so the main wash valve needs to be opened to open the main wash hose, allowing water to enter the main wash chamber and flush the laundry detergent into the drum.

[0080] However, if users mistakenly put the laundry detergent into the pre-wash chamber due to confusion between the main wash chamber and the pre-wash chamber, and then open the main wash valve during the main wash stage to rinse the main wash chamber, the laundry detergent cannot be added into the drum. As a result, the laundry detergent cannot act on the clothes, or rather, the laundry detergent and disinfectant cannot perform their respective functions effectively, leading to clothes that are not cleaned properly.

[0081] To reduce the occurrence of the above situation, this application embodiment adds a rinsing process for the pre-wash chamber during the main wash stage. This process can flush the laundry detergent that has been mistakenly placed in the pre-wash chamber into the drum, thereby allowing the laundry detergent to play its role during the main wash stage and improving the cleanliness of the clothes.

[0082] For example, the water intake sequence can be set during the main wash stage, that is, water enters from the pre-wash chamber first during the main wash stage, so that the laundry detergent can be put into the drum and achieve the cleaning effect on the clothes regardless of whether the user puts the laundry detergent in the wrong place.

[0083] Specifically, the pre-wash valve is controlled to operate at a second preset on / off ratio and for a second duration to flush the liquid in the pre-wash chamber into the drum. The second preset on / off ratio can be 1. For example, the pre-wash valve is controlled to open for 5 seconds, close for 5 seconds, and continue the above on / off cycle for 30 seconds to flush the liquid, such as disinfectant, in the pre-wash chamber into the drum. This can effectively flush the pre-wash chamber, thereby preventing disinfectant from adhering to the pre-wash chamber, reducing the problem of clothing contamination caused by disinfectant adhesion, and improving the utilization rate of disinfectant and reducing material waste.

[0084] 303. After the pre-wash valve is closed for a preset time, the main wash valve is controlled to operate at a first preset on / off ratio and continue for a first time to flush the liquid in the main wash chamber into the drum.

[0085] During the main wash stage, regardless of whether the laundry detergent is mistakenly placed in the pre-wash chamber, the main wash valve can be opened and the main wash pipe can be connected, thereby allowing water to enter and flush the liquid in the main wash chamber into the drum, thus increasing the probability of laundry detergent entering the drum and improving the probability of clothes being cleaned.

[0086] If the main wash valve is opened immediately after the pre-wash valve is closed, the water in the pre-wash tube will not have drained completely, and the water in the main wash tube will counteract it. This will cause the fabric softener in the softening chamber to be lost too early, resulting in waste of the fabric softener and preventing it from softening the clothes.

[0087] Therefore, in order to reduce the occurrence of this situation, in this embodiment of the application, after the pre-wash valve is closed, the main wash valve is opened after a preset time interval, such as 5 seconds, to drain the water in the pre-wash tube, thereby reducing the phenomenon of premature loss of fabric softener caused by counter-current in the fabric softener chamber.

[0088] Specifically, after the pre-wash valve is closed for a preset time, the main wash valve is controlled to operate at a first preset on / off ratio for a first duration to flush the liquid in the main wash chamber into the drum. The first preset on / off ratio can also be 1. For example, the main wash valve is controlled to open for 5 seconds, close for 5 seconds, and continue this on / off cycle for 30 seconds to flush the liquid, such as laundry detergent, in the main wash chamber into the drum. This flushes the main wash chamber, preventing laundry detergent from adhering to it and reducing the problem of laundry detergent staining clothes. It also improves the utilization rate of laundry detergent and reduces material waste.

[0089] The first preset start-stop ratio can be less than or equal to the second preset start-stop ratio, and the first duration can be less than or equal to the second duration, so as to fully deliver the laundry detergent that was mistakenly put into the pre-wash chamber into the drum and improve the treatment effect on the clothes.

[0090] 304. In the final rinse sub-stage of the rinsing phase, the pre-rinse valve and the main rinse valve are controlled to operate at the same on / off ratio and continue for a third duration to flush the softening liquid in the softening chamber into the drum.

[0091] In the final rinse sub-stage of the rinsing process, after the clothes have been cleaned, fabric softener can be added to soften them and reduce problems such as hardening and wrinkles. During this stage, the pre-wash valve and main wash valve can be controlled to operate at the same on / off ratio for a continuous duration to flush the fabric softener from the softening chamber into the drum.

[0092] The pre-wash valve and the main wash valve operate with the same on / off ratio, meaning that the pre-wash valve and the main wash valve open and close simultaneously, or the pre-wash valve and the main wash valve have at least overlapping opening times. This allows the water flowing out of the pre-wash pipe and the main wash pipe to flush each other, change the water flow path, and enter the softening chamber, thus realizing the process of putting the softening liquid in the softening chamber into the drum.

[0093] For example, controlling the pre-wash valve and the main wash valve to open for 5 seconds and close for 5 seconds simultaneously, and continuing this opening and stopping cycle for 30 seconds, can flush the fabric softener in the softening chamber into the drum. This can effectively flush the softening chamber, thereby preventing the fabric softener from adhering to the pre-wash chamber, reducing the problem of fabric softener staining clothes, and improving the utilization rate of the fabric softener, thus reducing material waste.

[0094] In the washing machine control method provided in this application embodiment, by adding a rinsing motion to the pre-wash chamber during the main wash stage, the washing liquid can be added into the drum even if the user mistakenly puts it into the pre-wash chamber, thereby increasing the probability of the washing liquid acting on the clothes and improving the cleaning effect. Furthermore, it increases the washing machine's tolerance for incorrect liquid placement, making the washing machine more intelligent and improving the user experience. Opening the main wash valve after the pre-wash valve has been closed for a preset time reduces the phenomenon of backwashing in the softener chamber, thus reducing the problem of premature loss of softener and improving the treatment effect on clothes. Moreover, by operating the main wash valve and the pre-wash valve according to a set on / off ratio, the main wash chamber, pre-wash chamber, and softener chamber can be rinsed separately, reducing the probability of liquid adhesion in each chamber. This improves the utilization rate of functional liquids and reduces contamination of the water inlet box, further enhancing the cleaning effect on clothes.

[0095] Please see Figure 4 As shown, Figure 4 This is a fourth flowchart illustrating the control method for a washing machine provided in an embodiment of this application. This application also provides a control method for a washing machine, including:

[0096] 401. In the washing stage other than the last rinsing sub-stage of the rinsing stage, control the pre-rinse valve to open and open the pre-rinse pipe to flush the liquid in the pre-rinse chamber into the drum.

[0097] 402. After the pre-wash valve has been closed for a preset time, control the main wash valve to open and connect the main wash pipe to flush the liquid in the main wash chamber into the drum.

[0098] Regarding steps 401 and 402:

[0099] Since the use of fabric softener is more effective in the final rinsing sub-stage of the rinsing process, the pre-rinse valve and the main rinse valve are opened simultaneously, allowing water to enter the pre-rinse pipe and the main rinse pipe at the same time to flush into the softening chamber and dispensing the fabric softener.

[0100] However, in the washing stages other than the final rinse sub-stage, it is necessary to reduce the backflow caused by the simultaneous intake of water into the pre-rinse and main rinse tubes to minimize the risk of premature loss of fabric softener. Therefore, in this embodiment, when it is necessary to control the opening of the pre-rinse valve and the main rinse valve during the washing stages other than the final rinse sub-stage, the main rinse valve can be opened only after the pre-rinse valve has been closed for a preset time and the water in the pre-rinse tube has drained completely. This can reduce the backflow of water between the pre-rinse and main rinse tubes.

[0101] In the washing machine control method provided in this application embodiment, during the washing stage other than the last rinsing sub-stage of the non-rinsing stage, by opening the pre-wash valve and the main wash valve at preset intervals, the phenomenon of premature loss of fabric softener caused by the water flowing out of the pre-wash pipe and the main wash pipe colliding and failing to soften the clothes can be reduced, thereby improving the treatment effect on the clothes.

[0102] To facilitate better implementation of the washing machine control method of this application embodiment, this application embodiment also provides a washing machine control device. Please refer to... Figure 5 , Figure 5 This is a schematic diagram of the control device for a washing machine provided in an embodiment of this application. The structural composition of the washing machine can be referred to the above description, and will not be repeated here. The control device 500 for the washing machine includes a first control unit 501 and a second control unit 502.

[0103] The first control unit 501 is used to control the opening of the pre-wash valve and to connect the pre-wash pipe during the main wash stage so as to flush the liquid in the pre-wash chamber into the drum.

[0104] The second control unit 502 is used to control the opening of the main wash valve and to connect the main wash pipe so as to flush the liquid in the main wash chamber into the drum.

[0105] All of the above technical solutions can be combined in any way to form optional embodiments of this application, and will not be described in detail here.

[0106] In the control device 500 of the washing machine provided in this application embodiment, by adding a rinsing of the pre-wash chamber during the main wash stage, the washing liquid can be added into the drum even if the user mistakenly puts the washing liquid into the pre-wash chamber, thereby increasing the probability of the washing liquid acting on the clothes and improving the cleaning effect on the clothes; in addition, it can also increase the washing machine's tolerance for incorrect placement of washing liquid, making the washing machine more intelligent and improving the user experience.

[0107] Accordingly, this application also provides a washing machine; please refer to the embodiments provided. Figure 6 and Figure 7 As shown, Figure 6 This is a schematic diagram of the structure of a washing machine provided in an embodiment of this application. Figure 7 This is a schematic diagram of the water inlet box in a washing machine provided in an embodiment of this application. The washing machine 600 includes a drum 601 and a water inlet box 602. The drum 601 is used to hold clothes and can drive the clothes to rotate, so as to clean the clothes by tumbling them in conjunction with the action of laundry detergent. The water inlet box 602 is provided corresponding to the drum 601, and the water inlet box 602 is provided with a pre-wash chamber 6021, a main wash chamber 6022, and a softening chamber 6023 for holding disinfectant, laundry detergent, and fabric softener, respectively. The softening chamber 6023 is disposed between the pre-wash chamber 6021 and the main wash chamber 6022.

[0108] The washing machine 600 also includes a pre-wash pipe 603, a pre-wash valve 604, a main wash pipe 605, and a main wash valve 606. The pre-wash pipe 603 is positioned towards the pre-wash chamber 6021 to deliver water into the pre-wash chamber 6021, thereby flushing the liquid in the pre-wash chamber 6021 into the drum 601. The pre-wash valve 604 is used to open or close the pre-wash pipe 603, that is, the opening and closing of the pre-wash valve 604 controls whether the pre-wash chamber 6021 is rinsed. The main wash pipe 605 is positioned towards the main wash chamber 6022 to deliver water into the main wash chamber 6022, thereby flushing the liquid in the main wash chamber 6022 into the drum 601.

[0109] In order to reduce costs and increase efficiency in washing machines, the relevant technology replaces the original pre-wash pipe and pre-wash valve, main wash pipe and main wash valve, and softening pipe and softening valve corresponding to the pre-wash chamber, main wash chamber, and softening chamber with a pre-wash pipe and pre-wash valve and a main wash pipe and main wash valve. Water enters through the pre-wash pipe and main wash pipe at the same time, and the water flow flushes into the softening chamber between the main wash chamber and the pre-wash chamber, thereby saving softening pipes and softening valves and reducing the manufacturing cost of washing machines.

[0110] For example, the pre-wash pipe 603 is arranged opposite to the main wash pipe 605 so that when water enters the pre-wash pipe 603 and the main wash pipe 605 at the same time, the softening liquid in the softening chamber 6023 is flushed into the roller 601.
