Description

Technical Field

[0001] The present application relates to the technical field of washing machines, and in particular to a washing machine. Background Art

[0002] A washing machine is a household appliance used to wash clothes. Currently, the mainstream washing machines on the market include front-loading washing machines and pulsator washing machines. Regardless of the type of washing machine, before starting to wash clothes, detergent must be added to the washing tub and water must be added to the washing machine to dissolve the substances in the clothes in the tub, thereby facilitating the washing of the clothes.

[0003] In the related art, washing machines use a continuous water supply method to add water into the washing machine until the water level reaches a preset target water level, and then control the washing tub to rotate to wash. In this way, when the washing machine starts washing, the detergent added has been diluted by a large amount of water, resulting in a low concentration of detergent in the water in the washing tub, resulting in poor cleaning effect.

[0004] Therefore, there is an urgent need for a washing machine that can improve cleaning effect. Summary of the Invention

[0005] In order to solve the above technical problems, an embodiment of the present application provides a washing machine.

[0006] According to one aspect of an embodiment of the present application, the embodiment of the present application provides a washing machine, comprising: a housing; a liquid soap box disposed in the housing; the liquid soap box is used to hold a detergent solution; a first water inlet pipe connected to the liquid soap box; the first water inlet pipe is used to input water into the liquid soap box, so that the water and the detergent solution are combined to form a washing water solution; a washing tub disposed in the housing; the washing tub is used to hold clothes to be washed; a second water inlet pipe is connected to the liquid soap box; the second water inlet pipe is used to discharge the washing water solution into the washing tub; a drive motor is used to provide rotational power to the washing tub; a controller is electrically connected to the drive motor, the controller being configured to perform the following steps: in response to a preset washing instruction, controlling the drive motor to operate at a preset motor speed; and controlling the first water inlet pipe and the second water inlet pipe to respectively inflate water multiple times to discharge the washing water solution into the washing tub.

[0007] In the above embodiment, in response to a preset wash command, the drive motor is first controlled to operate at a preset motor speed, and then the first and second water inlet pipes are controlled to flow water multiple times to discharge the washing solution into the washing tub. Thus, compared to continuously flowing water and then controlling the washing tub to rotate after the water flow is completed, first controlling the drive motor to operate at a preset motor speed to rotate the washing tub, and then controlling the first and second water inlet pipes to flow water multiple times, reduces the amount of water required for a single water inflow and increases the concentration of the detergent solution in the washing solution. This allows the high-concentration washing solution to evenly soak the laundry as the washing tub rotates, thereby improving the washing effect.

[0008] In one embodiment of the present application, based on the aforementioned scheme, the controller is further configured to perform the following steps: obtaining a first real-time water inlet number corresponding to the first water inlet pipeline and a second real-time water inlet number corresponding to the second water inlet pipeline; and controlling the first water inlet pipeline and the second water inlet pipeline to inlet water multiple times according to the first real-time water inlet number and the second real-time water inlet number.

[0009] In the above embodiment, by repeatedly controlling the water inflow into the first water inlet pipe and the second water inlet pipe according to the first real-time water inflow number corresponding to the first water inlet pipe and the second real-time water inflow number corresponding to the second water inlet pipe, the water inflow into the first water inlet pipe and the second water inlet pipe is repeatedly controlled, thereby achieving repeated control of the water inflow into the first water inlet pipe and the second water inlet pipe, so that all the washing water solution can be discharged into the washing tub.

[0010] In one embodiment of the present application, based on the aforementioned scheme, the controller is further configured to perform the following steps: when the second real-time water inlet number is the i-th time, controlling the start time of water inlet of the second water inlet pipeline to be between the first start time and the second start time; wherein, the first start time is the start time of the first water inlet pipeline when the first real-time water inlet number is the i-th time; the second start time is the start time of the first water inlet pipeline when the first real-time water inlet number is the i+1-th time; i is a positive integer.

[0011] In the above embodiment, after a sufficient amount of water is injected into the liquid soap box through the first water inlet pipe to mix with the detergent solution, the second water inlet pipe is opened to discharge the detergent solution in the liquid soap box into the washing tub. After partially draining the detergent solution, the first water inlet pipe is restarted to mix with the remaining detergent solution. This repetitive process allows the entire detergent solution in the liquid soap box to be mixed and diluted before being discharged into the washing tub. Furthermore, since the water supply is not continuously increased, the concentration of the detergent solution in the washing water solution is increased, enabling a high-concentration washing water solution to be injected into the washing tub, thereby improving the washing effect.

[0012] In one embodiment of the present application, based on the aforementioned scheme, the controller is further configured to perform the following steps: when the second real-time water inlet number is the i-th time, controlling the end time of water inlet to the second water inlet pipe is between the first end time and the second end time; wherein, the first end time is the end time of water inlet to the first water inlet pipe when the first real-time water inlet number is the i-th time; the second end time is the end time of water inlet to the first water inlet pipe when the first real-time water inlet number is the i+1-th time; i is a positive integer.

[0013] In the above embodiment, multiple water inflows into the first water inlet pipe and the second water inlet pipe can be achieved. Compared with continuous water inflow, the concentration of the detergent solution in the washing water solution is increased, so that a high-concentration washing water solution can be injected into the washing tub, thereby improving the washing effect.

[0014] In one embodiment of the present application, based on the aforementioned scheme, the controller is further configured to perform the following steps: when the second real-time water inlet number is the i-th time, control the duration of water inlet through the second water inlet pipeline to be longer than the duration of the i-th end of water inlet through the first water inlet pipeline; wherein i is a positive integer.

[0015] In the above embodiment, before water enters the first water inlet pipe, part of the washing water solution in the liquid soap box can be discharged, so that there is space in the liquid soap box for water to be injected and mixed with the remaining detergent solution.

[0016] In one embodiment of the present application, based on the aforementioned scheme, the controller is further configured to perform the following steps: when the first real-time water inlet number is the i+1th time, control the duration of water inlet through the first water inlet pipeline to be longer than the duration of the i-th end of water inlet through the second water inlet pipeline; wherein i is a positive integer.

[0017] In the above embodiment, it is ensured that before water enters the second water inlet pipe, sufficient water is injected into the liquid soap box to be mixed with the remaining detergent solution to form a washing water solution, so that the second water inlet pipe can discharge the washing water solution into the washing tub.

[0018] In one embodiment of the present application, based on the above solution, the washing machine is provided with a nozzle; the nozzle is connected to the second water inlet pipe; the nozzle is used to spray the washing water solution into the washing tub.

[0019] In the above embodiment, the high-concentration washing water solution in the liquid soap box can be sprayed into the washing tub, so as to facilitate cleaning of the clothes in the washing tub.

[0020] In one embodiment of the present application, based on the aforementioned solution, the injection port of the nozzle is a fan-shaped opening.

[0021] In the above embodiment, the spraying area of ​​the washing water solution can be increased, so that the washing water solution can be sprayed onto the surface of the clothes in the barrel to achieve soaking, thereby improving the cleaning effect.

[0022] In one embodiment of the present application, based on the aforementioned solution, a siphon structure is provided in the liquid soap box; the siphon structure includes: a siphon column connected to the first water inlet of the second water inlet pipe; the siphon column is used to introduce the washing water solution into the second water inlet pipe; a siphon cap is mounted on the siphon column; the siphon cap is used to combine with the siphon column to introduce the washing water solution into the second water inlet pipe through the siphon effect.

[0023] In the above embodiment, the siphon structure can reduce the natural outflow of detergent solution after the user adds it, so that the detergent solution or washing water solution in the liquid soap box needs to reach a preset height before it can flow out through the siphon effect.

[0024] In one embodiment of the present application, based on the above solution, the aperture of the second water inlet pipe is reduced at the first water inlet.

[0025] In the above embodiment, the second water inlet pipe forms a Venturi tube, so that the water flow in the Venturi tube creates a pressure difference. This creates a pressure difference between the two ends of the siphon structure, that is, between the washing water in the liquid soap box and the water at the first water inlet. This facilitates the siphon effect to draw the washing water in the liquid soap box to the first water inlet and discharge it into the washing tub.

DETAILED DESCRIPTION

[0037] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0038] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0040] It should also be noted that the term "plurality" used in this application refers to two or more than two. "And / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0041] In the specification, claims, and drawings of this application, the terms "first," "second," "third," and "fourth," etc., are used to distinguish different objects, not to describe a particular order.

[0042] Currently, washing machines often use a method of continuously adding water until the water level reaches a preset target water level. After the water is added, the washing tub is controlled to rotate for washing. As a result, when the washing machine starts washing, the added detergent has been diluted by a large amount of water, resulting in a low concentration of detergent in the water in the washing tub, which leads to poor cleaning effect of the washing machine.

[0043] In order to solve the above technical problems, the present application proposes a washing machine that can improve the cleaning effect.

[0044] See also Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the circuit connection principle of a washing machine provided by an exemplary embodiment of the present application. Figure 2 It is a structural schematic diagram of a washing machine provided by an exemplary embodiment of the present application.

[0045] like Figure 1 and Figure 2 As shown, the washing machine 10 can be a pulsator washing machine or a drum washing machine, etc., which is not limited here.

[0046] Washing machine 10 may include a housing 11. Housing 11 is the outer structure of washing machine 10, used to secure and protect internal components. Housing 11 is typically made of metal or plastic. Housing 11 is also typically provided with a door. Users can place laundry into the washing tub through this door.

[0047] Casing 11 is also usually provided with display screen and control panel, and button, knob or touch screen are arranged on the control panel. User can control washing machine through control panel and check the cleaning situation of washing machine through display screen.

[0048] The washing machine 10 may include a washing tub 12. The washing tub 12 is disposed inside the housing 11 and is typically made of stainless steel for accommodating clothes to be washed. The washing tub 12 rotates to wash the clothes.

[0049] The washing machine 10 may include a detergent dispenser 13. The detergent dispenser 13 is used to contain detergent and dispense the detergent into the washing tub.

[0050] It should be noted that detergents include detergent powders and detergent solutions.

[0051] See also Figure 3 , Figure 3 This is a structural diagram of a detergent dispensing device.

[0052] like Figure 3 As shown, the detergent dispensing device 13 may include a soap box.

[0053] The soap box may include a solid soap box 31. The solid soap box is used to contain detergent powder. A main water inlet 37 is provided at the bottom of the solid soap box; the main water inlet 37 is used to discharge water into the washing tub.

[0054] The soap box may include a liquid soap box 32. The liquid soap box 32 is used to contain a detergent solution.

[0055] The solid soap box 31 and the liquid soap box 32 are separated by an isolation plate 38. The isolation plate 38 is lower than the height of the solid soap box 31 and the liquid soap box 32. When the liquid soap box is filled with liquid, excess liquid can enter the solid soap box from above the isolation plate and then enter the washing tub through the main water inlet at the bottom of the solid soap box.

[0056] The detergent dispensing device 13 may include a first water inlet pipe. One end of the first water inlet pipe is connected to a water source, which may be a faucet. The other end of the first water inlet pipe is connected to the liquid soap box 32.

[0057] The first water inlet pipe is used to input water into the liquid soap box so that the water and the detergent solution are combined to form a washing water solution.

[0058] The detergent dispensing device 13 may include a first water inlet valve 33. This first water inlet valve 33 connects the first water inlet pipe to the liquid soap box 32. The first water inlet valve 33 is used to control the first water inlet pipe. For example, when the first water inlet valve is open, the first water inlet pipe can smoothly supply water to the liquid soap box. When the first water inlet valve is closed, the first water inlet pipe stops supplying water to the liquid soap box.

[0059] The detergent dispensing device 13 may include a siphon structure 34 . The siphon structure 34 is disposed in the liquid soap box 32 .

[0060] The siphon structure 34 may include a siphon column connected to the first water inlet of the second water inlet pipe and used to introduce the washing water in the liquid soap box into the second water inlet pipe.

[0061] The siphon structure 34 may include a siphon cap. The siphon cap is mounted on the siphon column. The siphon cap is used to combine with the siphon column to introduce the washing water solution into the second water inlet pipe through the siphon effect.

[0062] In this way, the siphon structure can reduce the natural outflow of detergent solution after the user adds it, so that the detergent solution or washing water solution in the liquid soap box needs to reach a preset height before it can flow out through the siphon effect.

[0063] The detergent dispensing device 13 may include a second water inlet pipe connected to the liquid soap box.

[0064] It should be noted that the first water inlet of the second water inlet pipe is connected to the siphon column of the siphon structure 34 of the liquid soap box. The second water inlet of the second water inlet pipe is connected to a water source, such as a faucet, via a second water inlet valve 35. The water outlet of the second water inlet pipe is connected to the washing tub 12. The first water inlet is located between the second water inlet and the water outlet.

[0065] The second water inlet pipe is used to discharge the washing water solution into the washing tub, that is, the washing water solution is discharged into the washing tub at the same time as the water is taken in.

[0066] Furthermore, the second water inlet pipe has a narrower diameter at the first water inlet. This creates a Venturi tube, creating a pressure differential in the water flow within the Venturi tube. This creates a pressure differential between the two ends of the siphon structure—the washing water in the liquid soap box and the water at the first water inlet. This allows the washing water in the liquid soap box to be drawn into the first water inlet through the siphon effect and discharged into the washing tub.

[0067] The detergent dispensing device 13 may include a second water inlet valve 35. One end of the second water inlet valve 35 is connected to a water source, and the other end of the second water inlet valve 35 is connected to a second water inlet of a second water inlet pipe.

[0068] The second water inlet valve 35 is used to control the second water inlet pipeline.

[0069] In an optional embodiment of the application, when the second water inlet valve 35 is open, water from the water source flows into the second water inlet pipe through the second water inlet. Because the second water inlet pipe's aperture is reduced at the first water inlet, the pipe between the second water inlet and the water outlet forms a Venturi tube, creating a pressure differential for the water flow within the Venturi tube. If the liquid soap box contains detergent solution, a pressure differential also exists between the two ends of the siphon structure, namely, the detergent solution in the liquid soap box and the water at the first water inlet. Under this pressure differential, the siphon structure, through the siphon effect, draws the detergent solution from the liquid soap box to the first water inlet, where it enters the second water inlet pipe and is then discharged into the washing tub.

[0070] The detergent dispensing device 13 may include a nozzle 36. The nozzle 36 is located above the washing tub and is connected to the outlet of the second water inlet pipe. The nozzle 36 is used to spray the detergent solution into the washing tub. This allows the highly concentrated detergent solution in the liquid soap box to be sprayed into the washing tub, facilitating the cleaning of the laundry within the tub.

[0071] Furthermore, the spraying port of the nozzle is a fan-shaped opening. In this way, the spraying area of ​​the washing water can be increased, so that the washing water can be sprayed onto the surface of the clothes in the barrel to achieve soaking, thereby improving the cleaning effect.

[0072] In an optional embodiment of the present application, please refer to Figure 4 , Figure 4 It is a side view of the detergent dispensing device.

[0073] like Figure 4 As shown, a siphon cap 41 is located within the liquid soap box 32 and is mounted on a siphon column 42. The siphon column 42 is connected to the first water inlet 43 of the second water inlet pipe, and the aperture at the first water inlet 43 is reduced. The second water inlet 44 of the second water inlet pipe is connected to a water source. The water outlet 45 of the second water inlet pipe is connected to the spray nozzle 36. Washing water is present in the liquid soap box, and water from the water source flows into the second water inlet pipe through the second water inlet. Because the aperture of the second water inlet pipe is reduced at the first water inlet, the pipe between the second water inlet and the water outlet forms a Venturi tube, creating a pressure differential within the Venturi tube. Consequently, a pressure differential exists between the two ends of the siphon structure—that is, between the washing water in the liquid soap box and the water at the first water inlet. Under this pressure differential, the siphon structure, through the siphon effect, draws the washing water from the liquid soap box into the first water inlet, where it enters the spray nozzle and is sprayed into the washing tub.

[0074] The washing machine 10 may include a drive motor 14 .

[0075] The drive motor 14 is the power source of the washing machine 10 and is responsible for rotating the washing tub 12 to rotate the clothes in the drum.

[0076] The washing machine 10 may include a controller 15 .

[0077] The controller 15 is electrically connected to the driving motor 14 , the first water inlet valve 33 , and the second water inlet valve 35 , respectively.

[0078] See also Figure 5 , Figure 5 5 is a flowchart of steps that can be executed by a controller in a washing machine according to an exemplary embodiment of the present application. The controller can be configured to execute the following steps S510 to S520:

[0079] Step S510: In response to a preset washing instruction, the driving motor is controlled to run at a preset motor speed.

[0080] Step S520: Controlling the first water inlet pipe and the second water inlet pipe to supply water multiple times to discharge the washing water into the washing tub.

[0081] The following describes these two steps in detail respectively.

[0082] In step S510, the preset washing instruction is a control instruction instructing the dryer to start washing clothes.

[0083] In some optional embodiments, such as Figure 6 As shown, Figure 6 A schematic diagram of a scenario in which a washing machine obtains a preset washing instruction is provided as an exemplary embodiment of the present application. Figure 6 As shown, after user 61 places laundry into the washing tub, they press a button on the control panel 62 of washing machine 10 indicating the start of washing. Washing machine 10 detects this and automatically generates a preset washing instruction. This process can be considered as the user issuing the preset washing instruction to the washing machine via the control panel.

[0084] In other optional embodiments, such as Figure 7 As shown, Figure 7 A schematic diagram of a scenario in which a washing machine obtains a preset washing instruction is provided as another exemplary embodiment of the present application. Figure 7 As shown, after user 61 places the laundry into the washing tub, the user sends a preset washing instruction to washing machine 10 via a control program for the washing machine on a user terminal 71, such as a mobile phone, tablet, or smartwatch. Upon receiving the washing instruction sent by user terminal 71, washing machine 10 controls the drive motor to operate at a preset motor speed.

[0085] It should be noted that controlling the drive motor to operate according to a preset motor speed, i.e., controlling the drive motor to rotate at a preset speed, wherein the preset speed is the target speed of the motor. The target speed can be a preset default speed or can be calculated based on the mass of the laundry to be washed.

[0086] In an optional embodiment of the present application, the driving motor can be controlled to control the washing tub to rotate unidirectionally, bidirectionally, or alternately. The specific rotation mode can be set according to actual conditions and is not limited here.

[0087] In step S520, water is fed into the first water inlet pipe by controlling the first water inlet valve, and water is fed into the second water inlet pipe by controlling the second water inlet valve.

[0088] In one embodiment of the present application, the first water inlet valve is controlled to control water inflow into the first water inlet pipe, that is, the first water inlet valve is opened to control water inflow into the first water inlet pipe; the first water inlet valve is closed to control water inflow into the first water inlet pipe. The second water inlet valve is controlled to control water inflow into the second water inlet pipe, that is, the second water inlet valve is opened to control water inflow into the second water inlet pipe; the second water inlet valve is closed to control water inflow into the second water inlet pipe.

[0089] It should be noted that if the first and second water inlet pipes are not separately controlled for multiple water inflows, unmelted detergent solution may remain in the liquid soap box, or undischarged washing water may remain, resulting in insufficient detergent solution in the washing tub, which may affect the washing performance of the washing machine. Separately controlling the first and second water inlet pipes for multiple water inflows allows the detergent solution or washing water solution in the liquid soap box to be emptied, thereby improving the washing performance of the washing machine.

[0090] Furthermore, the controller is further configured to perform the following steps: obtaining a first real-time water inflow count corresponding to the first water inflow pipe and a second real-time water inflow count corresponding to the second water inflow pipe; and controlling the first water inflow pipe and the second water inflow pipe to inflow water multiple times based on the first real-time water inflow count and the second real-time water inflow count. In this way, by repeatedly controlling the first water inflow pipe and the second water inflow pipe to inflow water multiple times based on the first real-time water inflow count corresponding to the first water inflow pipe and the second real-time water inflow count corresponding to the second water inflow pipe, repeated control of the water inflow to the first water inflow pipe and the second water inflow pipe is achieved, thereby enabling all the washing solution to be discharged into the washing tub.

[0091] The interval time for water inletting into the first water inlet pipe can be set according to actual conditions and is not limited here.

[0092] Furthermore, the controller is further configured to perform the following steps: when the second real-time water inflow frequency is the i-th time, controlling the start time of water inflow through the second water inlet pipe to be between the first start time and the second start time; wherein the first start time is the start time of the first water inlet pipe when the first real-time water inflow frequency is the i-th time; the second start time is the start time of the first water inlet pipe when the first real-time water inflow frequency is the i+1-th time; and i is a positive integer. In this way, after the first water inlet pipe injects a sufficient amount of water into the liquid soap box to mix with the detergent solution, the second water inlet pipe is opened to discharge the detergent solution in the liquid soap box into the washing tub. After partially discharging the detergent solution, the first water inlet pipe is restarted to mix with the unmixed detergent solution. This repetitive process allows the detergent solution in the liquid soap box to be completely mixed and diluted before being discharged into the washing tub. Furthermore, since water is not continuously inflowed, the concentration of the detergent solution in the washing water solution is increased, enabling a high-concentration washing water solution to be injected into the washing tub, thereby improving the washing effect.

[0093] It should be noted that the start time of controlling the water inlet to the second water inlet pipeline is between the first start time and the second start time, that is, the first water inlet pipeline is first controlled to perform the i-th water inlet, then the second water inlet pipeline is controlled to perform the i-th water inlet, and finally the first water inlet pipeline is controlled to perform the i+1-th water inlet. The first water inlet pipeline can be controlled to terminate the i-th water inlet before the second water inlet pipeline is controlled to perform the i-th water inlet. Alternatively, the second water inlet pipeline can be controlled to perform the i-th water inlet before the first water inlet pipeline is controlled to terminate the i-th water inlet. The specific order can be set according to actual conditions and is not limited here.

[0094] If the first real-time water inflow count is the first, the start time of the first water inlet line is the time after receiving the preset washing instruction and the first preset time is between 0 and 1 minute. During the first preset time, the drive motor can be controlled to operate at a preset motor speed.

[0095] If the second real-time water inflow count is the first, the start time of the second water inflow line is the time after the preset washing command is responded to, and the second preset time is between 0 and 11 minutes, and satisfies the requirement that it is between the first water inflow start time of the first water inflow line and the second water inflow start time of the first water inflow line.

[0096] Furthermore, the controller is further configured to perform the following steps: when the second real-time water inflow frequency is the i-th time, controlling the end time of water inflow to the second water inlet pipe to be between the first end time and the second end time; wherein the first end time is the end time of water inflow to the first water inlet pipe when the first real-time water inflow frequency is the i-th time; and the second end time is the end time of water inflow to the first water inlet pipe when the first real-time water inflow frequency is the (i+1)th time. In this way, multiple water inflows to the first and second water inlet pipes can be achieved, which increases the concentration of the detergent solution in the washing water solution compared to continuous water inflow, thereby enabling the high-concentration washing water solution to be injected into the washing tub, thereby improving the washing effect.

[0097] It should be noted that the end time of controlling the water inlet of the second water inlet pipeline is between the first end time and the second end time, that is, the first water inlet pipeline is first controlled to end the water inlet for the i-th time, then the second water inlet pipeline is controlled to end the water inlet for the i-th time, and then the first water inlet pipeline is controlled to end the water inlet for the i+1-th time. Among them, the second water inlet pipeline can be controlled to end the water inlet for the i-th time first, and then the first water inlet pipeline is controlled to end the water inlet for the i+1-th time. It is also possible to first control the first water inlet pipeline to end the water inlet for the i+1-th time, and then control the second water inlet pipeline to end the water inlet for the i-th time. The specific order can be set according to actual conditions and is not limited here.

[0098] Furthermore, the controller is further configured to execute the following step: when the second real-time water inflow frequency is the i-th time, controlling the duration of water inflow through the second water inlet pipe to be equal to or longer than the duration of the i-th water inflow termination through the first water inlet pipe. In this way, the detergent solution in the liquid soap box can be partially discharged before the first water inlet pipe is filled with water, allowing the space in the liquid soap box to be filled with water and mixed with the remaining detergent solution.

[0099] It should be noted that, when the second real-time water inflow frequency is the i-th, the duration of water inflow into the second water inlet pipeline is the duration of the i-th water inflow into the second water inlet pipeline, that is, the duration between the i-th opening of the second water inlet valve and the i-th closing of the second water inlet valve. The duration of the i-th end of water inflow into the first water inlet pipeline is the duration between the i-th closing of the first water inlet valve and the i+1-th opening of the first water inlet valve.

[0100] The duration of water inflow through the second water inlet pipe is between 0 and 5 minutes. If the duration is longer than 5 minutes, the detergent solution in the liquid soap box cannot flow into the second water inlet pipe. If water continues to flow in, the concentration of the detergent solution in the washing tub will be greatly diluted, resulting in a reduced cleaning effect of the washing machine.

[0101] The detergent is diluted with a large amount of water to obtain a low-concentration washing water solution, which will reduce the cleaning effect of the washing machine.

[0102] Furthermore, the controller is further configured to perform the following steps: when the first real-time water inflow frequency is the (i+1)th time, controlling the duration of water inflow through the first water inlet pipe to be equal to or longer than the duration of the second water inlet pipe ending the i-th water inflow. This ensures that before water inflow through the second water inlet pipe, sufficient water is injected into the liquid soap box to combine with the remaining detergent solution to form a washing water solution, so that the washing water solution can be discharged into the washing tub through the second water inlet pipe.

[0103] It should be noted that, when the first real-time water inflow frequency is the (i+1)th time, the duration of water inflow into the first water inlet pipeline is the duration of the (i+1)th water inflow into the first water inlet pipeline, that is, the duration between the (i+1)th opening of the first water inlet valve and the (i+1)th closing of the first water inlet valve. The duration of the i-th end of water inflow into the second water inlet pipeline is the duration between the i-th closing of the second water inlet valve and the (i+1)th opening of the second water inlet valve.

[0104] The duration of water inflow through the first water inlet pipe is within 0 to 10 minutes. If the duration is longer than 10 minutes, the detergent will be diluted by a large amount of water, resulting in a low-concentration washing water solution, which will reduce the cleaning effect of the washing machine.

[0105] In the embodiment of the present application, the drive motor is first controlled to operate at a preset motor speed in response to a preset washing instruction, and then the first and second water inlet pipes are controlled to flow water multiple times to discharge the washing solution into the washing tub. Thus, compared to continuously flowing water and then controlling the washing tub to rotate after the water flow is completed, first controlling the drive motor to move at a preset motor speed to rotate the washing tub, and then controlling the first and second water inlet pipes to flow water multiple times, reduces the amount of water in a single water flow, increases the concentration of the detergent solution in the washing solution, and enables the high-concentration washing solution to evenly soak the clothes to be washed when the washing tub rotates, thereby improving the washing effect.

[0106] See also Figure 8 , Figure 8 This is a timing diagram of a controller in a washing machine controlling water inflow into the second water inlet pipe and water inflow into the second water inlet pipe provided by an exemplary embodiment of the present application.

[0107] like Figure 8As shown, the first water inlet pipeline is receiving water during stages n1, n2, n3, ..., ni-1, and ni. The duration of water inlet in stage n1 is t11, the duration of water inlet in stage n2 is t12, the duration of water inlet in stage n3 is t13, ..., the duration of water inlet in stage ni is t1i, and the duration of water inlet in stage ni-1 is t1i-1. The durations of water inlet in stage n1 are t11, the duration of water inlet in stage n2 is t12, the duration of water inlet in stage n3 is t13, ..., the duration of water inlet in stage ni-1 is t1i-1, and the duration of water inlet in stage ni is t1i, all of which are greater than 0 minutes and less than 10 minutes. T11, T12, ..., and T1i-1 are the time intervals between the water inlet stages of the first water inlet pipeline.

[0108] The second water inlet pipeline is receiving water during stages N1, N2, N3, ..., Ni-1, and Ni. The duration of water inflow in stage N1 is t21, the duration of water inflow in stage N2 is t22, the duration of water inflow in stage N3 is t23, ..., the duration of water inflow in stage Ni is t2i, and the duration of water inflow in stage Ni-1 is t2i-1. The duration of water inflow in stage N1 is t21, the duration of water inflow in stage N2 is t22, the duration of water inflow in stage N3 is t23, ..., the duration of water inflow in stage Ni-1 is t2i-1, and the duration of water inflow in stage Ni is t2i, all of which are greater than 0 minutes and less than 5 minutes. T21, T22, ..., T2i-1 are the time intervals between the water inflow stages of the second water inlet pipeline.

[0109] The above-mentioned duration and the time interval between each water inlet stage of the first water inlet pipeline and the time interval between each water inlet stage of the second water inlet pipeline need to be set if the following conditions are met: the start time of the i-th water inlet stage of the second water inlet pipeline is between the start time of the i-th water inlet stage of the first water inlet pipeline and the start time of the i+1-th water inlet stage of the first water inlet pipeline; the end time of the i-th water inlet stage of the second water inlet pipeline is between the end time of the i-th water inlet stage of the first water inlet pipeline and the end time of the i+1-th water inlet stage of the first water inlet pipeline; Ni≥Ti; ni+1≥T2i.

[0110] Combine Figure 8As shown, after receiving the preset washing command, the drive motor is controlled to operate at a preset motor speed. Then, after a first preset time interval T10, the first water inlet valve is controlled to open to control water flow into the first water inlet pipe, entering stage n1. Then, the second water inlet valve is controlled to open to control water flow into the second water inlet pipe, entering stage N1. The interval between the time when the second water inlet valve is opened and the time when the preset washing command is received is a second preset time interval T20.

[0111] When water continues to flow into the first water inlet pipe for a duration of t11, the first water inlet valve is controlled to close, stopping water flow into the first water inlet pipe and exiting stage n1. Then, after a time interval of T11, the first water inlet valve is reopened to control water flow into the first water inlet pipe and enter stage n2. Then, the second water inlet valve is controlled to close, stopping water flow into the second water inlet pipe and exiting stage N1. Stage N1 lasts for t21. t21 is greater than T11. Then, after a time interval of T21, the second water inlet valve is controlled to open to control water flow into the second water inlet pipe and enter stage N2.

[0112] When water continues to flow into the first water inlet pipe for a duration of t12, the first water inlet valve is closed to stop water flow into the first water inlet pipe, exiting stage n2. t12 is greater than T21. Then, after a time interval of T11, the first water inlet valve is reopened to control water flow into the first water inlet pipe, entering stage n2. The second water inlet valve is then closed to stop water flow into the second water inlet pipe, exiting stage N1. Stage N1 lasts for t21.

[0113] The water inlet into the first water inlet pipe and the water inlet into the second water inlet pipe are controlled in sequence by the same method, which will not be described in detail here.

[0114] In this way, the water inlet timing and water inlet termination timing of each pipeline of the washing machine can be precisely controlled by the duration and interval of each stage, so that the detergent solution in the liquid soap box can be diluted multiple times, fully blended, and discharged into the washing tub, thereby reducing the amount of water inletted at a single time. As a result, the concentration of the detergent solution in the washing water solution is higher during water inlet. At the same time, by controlling the drive motor to move at a preset motor speed, the washing tub rotates, so that the high-concentration washing water solution can evenly soak the clothes to be washed, thereby improving the washing effect.
