Description

Technical Field

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

[0002] With the development of economy and the improvement of people's living standards, washing machines have entered thousands of households, providing convenience for people's lives.

[0003] Some current washing machines may include a variable liquid storage container for storing detergent, and the type of detergent in the variable liquid storage container can be changed. When the washing machine needs to process the clothes with water (such as washing and rinsing), the detergent in the variable liquid storage container needs to be pumped into the washing tub through a liquid guide pipe connected to the variable liquid storage container.

[0004] However, when the type of detergent in the variable liquid storage container is changed, the type of detergent before the change may still remain in the liquid conduit connected to the variable liquid storage container. If the changed detergent is used to treat the clothes with water, the changed detergent will be mixed with the detergent before the change and solidify when it is pumped into the liquid conduit connected to the variable liquid storage container, resulting in the blockage of the liquid conduit, and also causing the changed detergent to be insufficiently put into the washing tub, affecting the clothing treatment effect.

[0057] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0058] Various structural schematic diagrams according to embodiments of the present disclosure are shown in the accompanying drawings.

The shapes of various regions and layers shown in the figures and the relative sizes and positional relationships therebetween are only exemplary, and may deviate in practice due to manufacturing tolerances or technical limitations, and those skilled in the art may further design regions / layers with different shapes, sizes, and relative positions according to actual needs.

[0059] In the context of the present disclosure, when a layer / element is referred to as being "on" another layer / element, the layer / element may be directly on the other layer / element or an intervening layer / element may exist therebetween. In addition, if a layer / element is "on" another layer / element in one orientation, the layer / element may be "below" the other layer / element when the orientation is reversed.

[0060] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0061] The present application embodiment provides a washing machine control method, which is applied to a processor (not shown in the drawings) of the washing machine. Figure 1 As shown, the washing machine also includes a liquid pump (not shown in the drawings), at least one variable liquid storage container 101, a washing drum 103, and a first liquid conduit 102 connected to the variable liquid storage container 101. In an embodiment of the present application, the washing machine may include two liquid storage containers, one of which may store a fixed type of detergent, and the other may be a variable liquid storage container 101, and the type of detergent in the variable liquid storage container 101 may be changed. For example, the type of detergent in the liquid storage container may be changed from laundry detergent 301 to softener 302, or from softener 302 to laundry detergent 301, which is not limited here. Of course, in other embodiments, both of the above-mentioned two liquid storage containers may be variable liquid storage containers 101, which is not limited here. The liquid pump is used to pump the detergent from the variable liquid storage container 101 to the washing drum 103 through the first liquid conduit 102, and the liquid pump is electrically connected to the processor. Of course, the washing machine may also include more liquid storage containers (such as 3, or 4, etc.), as long as at least one of the liquid storage containers is a variable liquid storage container 101.

[0062] Specifically, Figure 2 As shown, the method provided in the embodiment of the present application includes:

[0063] S201: Receive clothing processing instructions.

[0064] Exemplarily, a human-computer interaction panel (not shown in the accompanying drawings) is also provided on the washing machine, and multiple clothing processing options can be displayed on the human-computer interaction panel. For example, multiple clothing processing options may include standard washing options, wool washing options, rinsing options, drying options, and dehydration options, etc., which are not limited here. The human-computer interaction panel can send clothing processing instructions to the processor in response to the user's triggering operation on any clothing processing option. Among them, the clothing processing instruction carries the clothing processing method corresponding to the clothing processing option selected to be triggered, so that the processor can receive the clothing processing instruction. In addition, the clothing processing instruction can also be sent by a terminal device (such as a mobile phone, or a smart bracelet, etc.), which is not limited here.

[0065] Furthermore, the laundry treatment method includes a method with water treatment or a method without water treatment. It can be understood that the laundry treatment methods corresponding to the standard washing option, the wool washing option, and the rinsing option are respectively the method with water treatment, and the laundry treatment methods corresponding to the drying option and the dehydration option are the method without water treatment.

[0066] S202: after the type of detergent is changed, determine whether it is necessary to clean the detergent remaining in the first liquid guiding tube 102, if yes, execute S203; if not, execute S205.

[0067] Exemplarily, the way to change the type of detergent can be:

[0068] After the user pours out the detergent in the variable liquid storage container 101, he / she re-puts a new type of detergent into the variable liquid storage container 101; or the user directly replaces the variable liquid storage container 101 storing the detergent of the previous type with the variable liquid storage container 101 storing the detergent of the later type.

[0069] Next, for the variable liquid storage container 101, the user can select the changed detergent type and click to confirm under the detergent type setting control on the human-machine interaction panel of the washing machine or the terminal device. In this way, all steps of changing the detergent type can be completed.

[0070] In addition, in some embodiments, the method for determining the need to clean the detergent remaining in the first liquid conduit 102 can be: if it is determined that the type of detergent pumped from the variable liquid storage container 101 through the first liquid conduit 102 to the washing drum 103 for the last time before the change is different from the type of detergent after the change, then it is determined that the detergent remaining in the first liquid conduit 102 needs to be cleaned.

[0071] For example, Figure 3As shown, the detergent remaining in the first liquid conduit 102 is the detergent that was pumped out from the variable liquid storage container 101 to the washing tub 103 through the first liquid conduit 102 for the last time before the change ( Figure 3 The detergent type and the detergent type after the change ( Figure 3 When the detergents of different types are different (the softener 302 in the figure), different types of detergents will be mixed in the first liquid conduit 102 later. At this time, it is determined that the detergent remaining in the first liquid conduit 102 needs to be cleaned.

[0072] It should be noted that determining that the residual detergent in the first liquid conduit 102 needs to be cleaned is not the only condition for cleaning the residual detergent in the first liquid conduit 102. It is also necessary to determine whether the conditions in the subsequent S203 are met.

[0073] In addition, if Figure 4 As shown, the type of detergent ( Figure 4 The detergent type after the change ( Figure 4 If the detergent type is the same as the laundry detergent 301, the type of detergent remaining in the first liquid conduit 102 is the same as the type of detergent after the change, so that different types of detergents will not be mixed in the first liquid conduit 102 in the future, so it can be determined that there is no need to clean the detergent remaining in the first liquid conduit 102. In this case, S205 can be directly executed.

[0074] Or, if Figure 5 As shown, the changed detergent type is laundry liquid 301, but it is determined that the detergent has not been pumped out from the variable liquid storage container 101 to the washing tub 103 through the first liquid conduit 102 before the change, which means that there is no residual detergent in the first liquid conduit 102, and thus different types of detergents will not be mixed in the first liquid conduit 102 later, so it can also be determined that there is no need to clean the residual detergent in the first liquid conduit 102. In this case, S205 can be directly executed.

[0075] S203: Determine whether the laundry treatment method is a water treatment method, if yes, execute S204; if no, execute S205.

[0076] It can be understood that the clothing processing method corresponding to the standard washing instruction, wool washing instruction, or rinsing instruction is a water-processing method, and the clothing processing method corresponding to the drying instruction or dehydration instruction is a non-water-processing method.

[0077] It should be noted that, when the laundry is treated without water (such as drying or dehydration), the detergent in the variable liquid storage container 101 will not be pumped into the first liquid conduit 102, and thus different types of detergents will not be mixed in the first liquid conduit 102. At this time, it can be directly determined that there is no need to clean the detergent remaining in the first liquid conduit 102. It can be understood that the order between S203 and S202 can be interchanged, which is not limited here.

[0078] S204: Control the liquid pump to discharge the residual detergent in the first liquid conduit 102.

[0079] Further, as Figure 1 As shown, the washing machine further includes a liquid separation box 104, a venturi tube 106, a second liquid guide tube 105, a third liquid guide tube 107, and a drain pipe (not shown in the drawings) provided with a drain valve and extending into the washing tub 103. The liquid outlet of the first liquid guide tube 102 is connected to the liquid separation box 104, and the liquid separation box 104 is also connected to the main water inlet pipe; the liquid inlet of the second liquid guide tube 105 is connected to the secondary water inlet pipe, the liquid outlet of the second liquid guide tube 105 is connected to the washing tub 103, the liquid inlet of the third liquid guide tube 107 is connected to the liquid separation box 104, and the liquid outlet of the third liquid guide tube 107 is connected to the washing tub 103.

[0080] Exemplarily, the main water inlet pipe can be controlled to flow water into the liquid separation box 104 to wet the liquid separation box 104 and prevent the subsequent detergent from sticking to the inner wall of the liquid separation box 104. Furthermore, the liquid pump can be controlled to rotate a preset number of circles (such as 8 circles, or 10 circles, etc.) or a preset duration (such as 8s, or 10s, etc.), and the residual detergent in the first liquid guide tube 102 can be discharged to the liquid separation box 104, and the second liquid guide tube 105 can be controlled to flow water. At this time, the venturi tube 106 generates negative pressure, and the detergent in the liquid separation box 104 is sucked into the second liquid guide tube 105, and the second liquid guide tube 105 discharges the detergent into the washing drum 103. Next, the drain valve is controlled to open to drain water into the washing drum 103, so that the detergent in the washing drum 103 can be flushed out from the drain port of the washing drum 103, and the entire detergent discharge step can be completed.

[0081] Furthermore, the residual detergent can be discharged in the following manner:

[0082] If it is detected that there is no lack of liquid in the first liquid conduit 102, the liquid pump is controlled to rotate a set first number of revolutions to discharge the residual detergent in the first liquid conduit 102. It can be understood that a liquid level sensor can be set in the first liquid conduit 102, and when the collected liquid level is equal to the set full liquid level threshold, it is determined that there is no lack of liquid in the first liquid conduit 102; at this time, the liquid pump is controlled to rotate a first number of revolutions to discharge the residual detergent in the first liquid conduit 102. The first number of revolutions refers to the number of revolutions that can discharge all the detergent in the first liquid conduit 102 after rotation.

[0083] Furthermore, if it is detected that there is no liquid in the first liquid conduit 102, the liquid pump is controlled to rotate a second number of revolutions to discharge the residual detergent in the first liquid conduit 102. When the liquid level detected by the liquid level sensor in the first liquid conduit 102 is lower than the set full liquid level threshold, it is determined that there is no liquid in the first liquid conduit 102 (when there is no liquid, such as Figure 3-Figure 5 As shown, the part of the first liquid conduit 102 that is not filled with detergent is usually air); at this time, the liquid pump is controlled to rotate the second number of revolutions to discharge the residual detergent in the first liquid conduit 102. On the one hand, the second number of revolutions can be less than the first number of revolutions, so that the residual detergent in the first liquid conduit 102 can be discharged while saving power consumption and time; on the other hand, the first number of revolutions can also be equal to the second number of revolutions, so that not only the residual detergent in the first liquid conduit 102 can be discharged, but also the residual air in the first liquid conduit 102 can be discharged. In this way, when the laundry processing operation is performed later, the required amount of changed detergent can be accurately pumped in.

[0084] S205: Execute the current laundry processing operation associated with the laundry processing instruction.

[0085] For example, when the laundry processing instruction is a standard washing instruction, the current laundry processing operation is a standard washing operation; when the laundry processing instruction is a rinsing instruction, the current laundry processing operation is a rinsing operation; when the laundry processing instruction is a quick wash instruction, the current laundry processing operation is a quick wash operation.

[0086] To summarize, a washing machine control method provided in an embodiment of the present application, after receiving a clothing processing instruction and after the type of detergent is changed, determines that it is necessary to clean the residual detergent in the first liquid conduit 102, and when the clothing processing method is a water treatment method, controls the liquid suction pump to operate to discharge the residual detergent in the first liquid conduit 102.

[0087] In this way, when the current clothing processing operation associated with the clothing processing instruction is subsequently executed, since the residual detergent in the first liquid conduit 102 has been discharged, when the changed detergent required for executing the clothing processing operation is pumped into the first liquid conduit 102, it will not mix with the residual detergent and solidify, so the smoothness of the first liquid conduit 102 can be maintained, and at the same time, the accuracy of the subsequent delivery amount of the changed detergent in the washing drum 103 is guaranteed, thereby ensuring the clothing processing effect.

[0088] In addition, after the type of detergent is changed, when it is determined that there is no need to clean the residual detergent in the first liquid conduit 102, or when it is determined that the residual detergent in the first liquid conduit 102 needs to be cleaned and the clothes are treated in a non-water manner, when the current clothes treatment operation associated with the clothes treatment instruction is executed, different types of detergents will not be mixed in the first liquid conduit 102, and the smoothness of the first liquid conduit 102 and the clothes treatment effect can be guaranteed.

[0089] Furthermore, the liquid pump is controlled to discharge the residual detergent in the first liquid tube 102 after receiving the instruction for treating the clothes with water, and the user is not aware of the discharge of the residual detergent in the first liquid tube 102; and when the residual detergent in the first liquid tube 102 needs to be cleaned but the clothes are treated without water, the user can sense it if the residual detergent in the first liquid tube 102 is discharged at this time; therefore, in this case, the liquid pump will not be controlled to discharge the residual detergent in the first liquid tube 102, but the residual detergent in the first liquid tube 102 will not be cleaned until the next time the residual detergent in the first liquid tube 102 needs to be cleaned and the clothes are treated with water, and the user will not sense it, thereby improving the user experience.

[0090] In addition, Figure 2 Based on the corresponding embodiments, whether or not to clean the detergent remaining in the first liquid conduit 102 can be determined based on at least one of the following:

[0091] when the detergent type was changed;

[0092] Detergent type before change;

[0093] Changed detergent types;

[0094] After the detergent type is changed, whether the detergent remaining in the first liquid conduit 102 has been cleaned;

[0095] Whether the changed detergent was used in the historical laundry processing operations after the detergent type was changed;

[0096] Historical laundry handling operations.

[0097] Furthermore, specific implementation methods for determining that the residual detergent in the first liquid conduit 102 needs to be cleaned may also include but are not limited to the following:

[0098] The first type: when it is determined that the detergent type before the change is different from the detergent type after the change, and the detergent remaining in the first liquid conduit 102 has not been cleaned after the change, the type of detergent remaining in the first liquid conduit 102 is different from the type of detergent after the change, so different types of detergents will be mixed in the first liquid conduit 102. In this way, it can be determined that the detergent remaining in the first liquid conduit 102 needs to be cleaned.

[0099] Exemplarily, each detergent type has a unique identifier, for example, the identifier of wool laundry detergent 301 may be "001", the identifier of antibacterial laundry detergent 301 may be "010", and the identifier of softener 302 may be "011". For example, when it is recognized that the type identifier of the detergent before the change is consistent with the type identifier of the detergent after the change, it is determined that the detergent type before the change is the same as the detergent type after the change.

[0100] Similarly, whether the residual detergent in the first liquid conduit 102 has been cleaned after the change can also be marked. For example, if the residual detergent in the first liquid conduit 102 has been cleaned after the change, it is marked "0", and if the residual detergent in the first liquid conduit 102 has not been cleaned after the change, it is marked "1". When the mark "0" is recognized, it is determined that the residual detergent in the first liquid conduit 102 has not been cleaned after the change.

[0101] Exemplarily, the detergent type before the change is wool laundry detergent 301, and the detergent type after the change is softener 302. If the wool laundry detergent 301 is not cleaned after the change, it can be determined that the wool laundry detergent 301 remaining in the first liquid conduit 102 needs to be cleaned.

[0102] Second: when the detergent type before the change is different from the detergent type after the change, and the changed detergent has not been used in the historical laundry processing operation after the detergent type is changed, it is determined that the detergent remaining in the first liquid conduit 102 needs to be cleaned.

[0103] Among them, the manner in which the detergent type before and after the change is different in this embodiment is the same as the above-mentioned implementation mode, and the manner in which it is determined that the changed detergent is not used in the historical clothing processing operation after the detergent type is changed is also the same as the above-mentioned manner, which will not be repeated here.

[0104] For example, the detergent type before the change is wool laundry detergent 301, and the detergent type after the change is softener 302, but after the change, a drying operation is performed (i.e., the historical clothing processing operation after the detergent type is changed), and softener 302 has not been used, then it means that wool laundry detergent 301 still remains in the first liquid conduit 102, and thus different types of detergents will be mixed in the first liquid conduit 102. In this way, it can be determined that the wool laundry detergent 301 remaining in the first liquid conduit 102 needs to be cleaned.

[0105] In the above Figure 2 Based on the corresponding embodiments, the specific implementation of S204 may include but is not limited to the following:

[0106] The first type: the water treatment method includes one or more water treatment stages. Before at least one water treatment stage, the liquid pump is controlled to work to discharge the detergent remaining in the first liquid conduit 102.

[0107] For example, if the water treatment method is a standard washing method, which includes a washing stage and a rinsing stage, the detergent remaining in the first liquid conduit 102 may be discharged before the washing stage; and / or the detergent remaining in the first liquid conduit 102 may be discharged before the rinsing stage. It can be understood that since the changed detergent is required in both the washing stage and the rinsing stage, in order to avoid the situation where different types of detergents are mixed in the first liquid conduit 102, the detergent remaining in the first liquid conduit 102 may be discharged before the washing stage and / or the rinsing stage.

[0108] Furthermore, before the first water treatment stage, the liquid pump can be controlled to work to discharge the residual detergent in the first liquid conduit 102. Similarly, the standard washing method includes a washing stage and a rinsing stage. Since the changed detergent is required in the washing stage, in order to prevent different types of detergents from mixing in the first liquid conduit 102 during the washing stage and the rinsing stage, the residual detergent in the first liquid conduit 102 can be discharged before the washing stage.

[0109] Furthermore, Figure 1 As shown, the washing machine further includes a drain pipe connected to the washing tub 103, and a drain port corresponding to the drain pipe and arranged in the washing tub 103. Furthermore, the drain pipe can be controlled to drain water to the drain port of the washing tub 103 while controlling the liquid pump to work to discharge the residual detergent in the first liquid conduit 102. Usually, the residual detergent in the first liquid conduit 102 will be discharged into the washing tub 103. When the drain pipe is controlled to drain water to the drain port of the washing tub 103, the detergent discharged into the washing tub 103 can be discharged from the drain port of the washing tub 103 to avoid contaminating the clothes when the clothes processing operation is performed later.

[0110] The second type: if at least one water treatment stage includes a water treatment stage compatible with the detergent before the change, the liquid suction pump is controlled to operate to discharge the residual detergent in the first liquid conduit 102 before the water treatment stage incompatible with the detergent before the change.

[0111] Exemplarily, whether a detergent is compatible with the water treatment stage refers to: if adding the detergent before the change to the first water treatment stage will cause a first change in a specific indicator in the first water treatment stage, and the function of the first water treatment stage is to cause a second change in the specific indicator, then the detergent before the change is incompatible with the first water treatment stage; otherwise, the detergent before the change is compatible with the first water treatment stage.

[0112] For example, when the detergent before the change is laundry liquid 301, the first change of the specific index refers to an increase in foam, and the second change of the specific index refers to a decrease in foam. The water treatment stage compatible with the detergent before the change (i.e., laundry liquid 301) is the washing stage (which will increase foam), and the water treatment stage incompatible with the detergent before the change (i.e., laundry liquid 301) is the rinsing stage (for reducing foam). Furthermore, the liquid pump can be controlled to work before the rinsing stage to discharge the residual laundry liquid 301 in the first liquid conduit 102. In this way, it can be avoided that the laundry liquid 301 contaminates the clothes during the rinsing stage.

[0113] For another example, when the detergent before the change is a heating agent, the first change of the specific indicator refers to heating the water temperature, and the second change of the specific indicator refers to lowering the water temperature. The water-treated stage that is compatible with the detergent before the change (i.e., the heating agent) is the clothing heating stage, and the water-treated stage that is incompatible with the detergent before the change (i.e., the heating agent) is the washing stage (cold water needs to be injected to lower the water temperature). Furthermore, the liquid suction pump can be controlled to work before the washing stage to discharge the residual heating agent in the first liquid conduit 102. In this way, it can be avoided that the heating agent enters the washing drum 103 during the washing stage, causing excessive water temperature and damage to the clothes.

[0114] The third type: As can be seen from the above, the liquid outlet of the first liquid conduit 102 is also connected to the liquid separator box 104, the first liquid outlet of the liquid separator box 104 is connected to the second liquid conduit 105, the liquid outlet of the second liquid conduit 105 is connected to the washing tub 103, and the detergent discharged from the liquid outlet of the second liquid conduit 105 is not easy to contaminate the clothes in the washing tub 103 (for example, the liquid outlet of the second liquid conduit 105 is located at the edge of the washing tub 103 and close to the drain outlet of the washing tub 103).

[0115] If the detergent before the change is incompatible with at least one water treatment stage, then before one of the incompatible water treatment stages, the liquid pump is controlled to operate to discharge the residual detergent in the first liquid conduit 102 and enter the washing drum 103 through the liquid separation box 104 and the second liquid conduit 105.

[0116] For example, if the detergent is laundry liquid 301, and one of the incompatible water treatment stages is the rinsing stage, the liquid pump can be controlled to work to discharge the residual detergent in the first liquid conduit 102 before the rinsing stage, and enter the washing tub 103 through the liquid separation box 104 and the second liquid conduit 105. In this way, it can be prevented that the laundry liquid 301 is pumped into the washing tub 103 during the rinsing stage and contaminates the clothes. Furthermore, before the first water treatment stage that is incompatible with the laundry liquid 301, the liquid pump can be controlled to work to discharge the residual laundry liquid 301 in the first liquid conduit 102, and enter the washing tub 103 through the liquid separation box 104 and the second liquid conduit 105, so that the residual laundry liquid 301 can be prevented from contaminating the clothes during the execution of the laundry treatment operations corresponding to all the incompatible water treatment stages.

[0117] Furthermore, it can be seen from the above that the washing machine further includes a drain pipe connected to the washing tub 103 and a drain port corresponding to the drain pipe and arranged on the washing tub 103. The liquid outlet of the second liquid guide pipe 105 is close to the drain port of the washing tub 103. Before at least one water treatment stage, the liquid pump is controlled to work to discharge the residual detergent in the first liquid guide pipe 102. While entering the washing tub 103 through the liquid separation box 104 and the second liquid guide pipe 105, the drain pipe is controlled to drain the water toward the drain port of the washing tub 103. In this way, when the drain pipe is controlled to drain the water toward the drain port of the washing tub 103, the detergent discharged into the washing tub 103 can be discharged from the drain port of the washing tub 103 to avoid contaminating the clothes when the clothes treatment operation is performed later.

[0118] In addition, the method provided in the embodiment of the present application also includes:

[0119] When it is determined that the detergent remaining in the liquid conduit needs to be cleaned after the detergent type is changed and the laundry treatment method is a method without water treatment (such as drying or dehydration), a prompt message for cleaning the residual detergent can be output to the human-machine interaction panel of the washing machine or the terminal device that issues the laundry treatment instruction. Exemplarily, the prompt message can be a voice prompt message "Please clean the residual detergent" or a text prompt message "Please clean the residual detergent", so as to remind the user that there is residual detergent in the first liquid conduit 102.
