[0010] In a specific implementation of the water inlet control method for the multi-drum washing machine described above, the step of "controlling the washing drum with water inlet pressure requirements to enter water according to the water inlet determination conditions" specifically includes: obtaining the user's washing habits; prioritizing the various water inlet determination conditions according to the user's washing habits; and controlling the washing drum with water inlet pressure requirements to enter water according to the prioritized water inlet determination conditions.

[0011] In a specific implementation of the water inlet control method for the multi-drum washing machine described above, the step of "prioritizing the various water inlet determination conditions according to the user's washing habits" specifically includes: if the user's washing habit is single-drum washing, the priority of the various water inlet determination conditions is as follows: the remaining running time of the washing drum has a higher priority than the heating requirement of the washing drum has a higher priority than the required water volume of the washing drum.

[0012] In a specific implementation of the water inlet control method for the multi-drum washing machine described above, the step of "prioritizing the various water inlet determination conditions according to the user's washing habits" further includes: if the user's washing habit is multi-drum washing, then first determine whether the washing drum has a heating requirement; if the washing drum has a heating requirement, then set the heating requirement of the washing drum as the highest priority of the water inlet determination conditions; if the washing drum does not have a heating requirement, then the priority of the various water inlet determination conditions is ranked as follows: the priority of the required water volume of the washing drum is higher than the priority of the remaining running time of the washing drum.

Attached Figure Description

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings, in which:

[0021] Figure 1 is a flowchart of the main steps of the water inlet control method for the multi-drum washing machine of the present invention;

[0022] Figure 2 is a possible complete flowchart of the water inlet control method of the multi-drum washing machine of the present invention. Detailed Implementation

[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0024] It should be noted that although the steps of the control method of the present invention are described in a specific order in the description of the present invention, these orders are not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in different orders.

[0025] The washing machine of the present invention includes a cabinet, within which at least two washing drums are disposed. Each washing drum is provided with a water inlet pipe connected thereto, and each washing drum can independently receive water and independently run a washing program. It should be noted that the number of washing drums and their positions within the cabinet can be set by those skilled in the art according to actual needs, and the present invention does not impose any limitations in this regard. Of course, the washing machine of the present invention can be a front-loading washing machine or a top-loading washing machine. The control method of the present invention will be described below using a front-loading washing machine as an example.

[0026] First, refer to Figure 1, which is a flowchart of the main steps of the water inlet control method for a multi-drum washing machine according to the present invention. As shown in Figure 1, when multiple drums need to be filled with water simultaneously, the control method of the present invention includes:

[0027] S1, obtain the current washing program of each washing drum that needs to be filled with water at the same time;

[0028] S2, determine whether each washing drum has an inlet water pressure requirement based on the washing program;

[0029] S3, determine the water inlet sequence for multiple washing drums that need to be filled with water simultaneously based on the judgment result.

[0030] The control method of the present invention further includes:

[0031] S4: When multiple washing drums do not require water pressure, control multiple washing drums to receive water simultaneously.

[0032] In step S1, the situation where multiple tubs need to be filled with water simultaneously includes both cases where the start time of water filling is exactly the same and cases where the difference in the start time of water filling is within a certain range, i.e., multiple tubs need to be filled with water at intervals of time t. In this case, there is also a situation where there is a water filling conflict between the multiple tubs. For example, suppose there are two washing tubs that need to be filled with water simultaneously, denoted as the first washing tub and the second washing tub, respectively. When the first washing tub is executing the water filling program, after an interval of time t, the water filling program of the first washing tub has not been completed, while the second washing tub also needs to execute the water filling program. At this time, there is a situation where there is a water filling conflict between the first washing tub and the second washing tub.

[0033] In step S2, a complete washing program includes water intake processes such as spraying, essence washing, lint removal, main wash water intake, and condenser water intake. Each washing drum has different water pressure requirements for its corresponding washing program. Specifically, when the washing drum is in the spraying, essence washing, or lint removal washing programs, these programs require water pressure. When the washing drum is in the main wash or condenser water intake programs, there is no water pressure requirement.

[0034] In step S3, the step of "determining the water inlet sequence of multiple washing drums that need to be filled with water simultaneously based on the judgment result" specifically includes:

[0035] S31, when at least one washing drum has a water inlet pressure requirement, obtain the number of washing drums with a water inlet pressure requirement;

[0036] S32 controls the water inlet sequence for each washing drum according to the number of drums being washed.

[0037] Specifically, when multiple washing drums are simultaneously running washing programs such as spraying, essence washing, and lint removal, these programs require specific water pressure. To ensure the required water pressure for each drum, each drum cannot be filled with water at the same time. For example, when the washing drum is running a spraying program, a certain water pressure is needed to rinse away the foam on the washing machine's window gasket and viewing window. To ensure that the required water pressure for each drum is met, each drum cannot be filled with water simultaneously. When multiple washing drums are simultaneously running washing programs such as main wash and condensate wash, these programs do not require specific water pressure. To improve washing efficiency, the washing machine can be set to allow multiple drums to fill with water simultaneously.

[0038] In step S32, the step of "controlling the water inlet sequence of each washing drum according to the number of washing drums" specifically includes:

[0039] S321, when the number of washing drums is equal to 1, first control the water inlet of the washing drum with water pressure requirement; then control the other washing drums to enter water at the same time.

[0040] In the above steps, when there is only one washing drum with water pressure requirement, that is, during this period, the washing program of that washing drum has water pressure requirement, then first control the water intake of that washing drum to ensure the water pressure. After the water intake of that washing drum is completed, then control the other washing drums without water pressure requirement to simultaneously intake water to ensure water intake efficiency.

[0041] S322, when the number of washing drums is greater than 1, first control the washing drums with water pressure requirements to enter water sequentially according to the water inlet judgment conditions; then control the other washing drums to enter water simultaneously.

[0042] The water inlet determination criteria include at least one of the following: the required water inlet volume of the washing drum, the remaining running time of the washing drum, and the heating requirement of the washing drum.

[0043] In the above steps, when there are multiple washing drums with water pressure requirements, the multiple washing drums are first controlled to enter water sequentially according to the water inlet judgment conditions to ensure water pressure. After the washing drums with water pressure requirements have entered water, the other washing drums without water pressure requirements are controlled to enter water simultaneously to ensure water inlet efficiency.

[0044] Furthermore, the present invention also includes the following special cases: during the same water intake period, when one or more washing drums simultaneously include two washing programs—one requiring water pressure and the other not—the washing drum first completes the water intake for the program requiring water pressure, and then simultaneously introduces the non-water pressure-requiring washing program with other washing drums that do not require water pressure. For example, during the same water intake period, when one washing drum simultaneously includes both spray and main wash water intake programs, and other washing drums include only the main wash water intake program, then that washing drum first performs spray water intake, and after the spray water intake is completed, it then simultaneously performs the main wash water intake with other washing drums.

[0045] Furthermore, the specific steps for determining the required water volume for the washing drum are as follows:

[0046] Obtain the water intake volume for each washing drum;

[0047] Control multiple washing drums to receive water sequentially in order of increasing water volume.

[0048] The specific steps for determining the remaining running time of the washing drum are as follows:

[0049] Get the remaining running time for each washing drum;

[0050] Control multiple washing drums to receive water sequentially in order of increasing remaining running time;

[0051] "Remaining runtime" refers to the remaining runtime of the entire washing cycle.

[0052] The specific steps for determining the heating requirement of the washing drum are as follows:

[0053] Obtain the number of the washing drums that require heating;

[0054] When the number of washing drums is equal to 1, the washing drum that requires heating is controlled to receive water first.

[0055] When the number of washing drums is greater than 1, control multiple washing drums to enter water sequentially in order of increasing heating time according to the heating requirements.

[0056] Specifically, the water inlet determination conditions mentioned above can be independent of each other when determining the water inlet order of the washing tub. That is, there is no logical relationship between the three determination conditions: the required water volume of the washing tub, the remaining running time of the washing tub, and the heating requirement of the washing tub. In practical applications, those skilled in the art can select at least one of them as the determination condition for which washing tub should be prioritized for water inlet, based on actual needs. Taking two washing tubs with water pressure requirements as an example, when the water inlet determination condition of the program is the required water volume of the washing tub, the washing tub with the lower required water volume is prioritized; when the water inlet determination condition of the program is the remaining running time of the washing tub, the washing tub with the shorter remaining running time is prioritized; and when the water inlet determination condition of the program is the heating requirement of the washing tub, the washing tub with the heating requirement is prioritized.

[0057] Of course, considering users' washing habits and the efficiency of multi-drum washing, there is also a logical relationship between the water inlet determination conditions mentioned above, specifically,

[0058] In step S322, the step of "controlling the washing drum with water pressure requirements to sequentially receive water according to the water inlet determination conditions" specifically includes:

[0059] S3221, obtains the user's washing habits;

[0060] S3222 prioritizes various water inlet detection conditions based on the user's washing habits;

[0061] S3223, control the washing drum with water pressure requirements to receive water according to the sorted water inlet judgment conditions.

[0062] Step S3222 specifically includes:

[0063] S32221, If ​​the user's washing habit is single-drum washing, the priority order of multiple water inlet determination conditions is as follows: the remaining running time of the washing drum has a higher priority than the heating demand of the washing drum, which has a higher priority than the required water inlet volume of the washing drum.

[0064] S32222, If the user's washing habit is multi-drum washing, first determine whether the washing drum needs heating;

[0065] S32223, If the washing drum requires heating, then set the heating requirement of the washing drum as the highest priority of the water inlet determination condition.

[0066] S32224 If the washing drum does not require heating, the priority order of various water inlet determination conditions is as follows: the priority of the required water inlet of the washing drum is higher than the priority of the remaining running time of the washing drum.

[0067] Specifically, if a user's washing habit is single-drum washing, the program determines that the user expects to complete the washing cycle of one drum first; that is, the program defaults to completing the washing cycle of multiple drums one by one as the washing standard. Therefore, when the user is washing multiple drums and all drums need to be filled with water simultaneously, the program first compares the remaining running time of each drum and controls the drums to be filled with water in ascending order of remaining running time. Further, if two or more drums have the same remaining running time, the program then determines the heating requirement of each drum and controls the drum requiring heating to be filled with water first. Going further, if two or more drums all require heating, the program controls the drums to be filled with water in ascending order of heating time required for heating. If two or more drums do not require heating, the program then compares the required water volume of each drum and controls the drums to be filled with water in ascending order of water volume required for heating.

[0068] If the user's washing habit is multi-drum washing, the program defaults to using efficiency as the washing standard. Therefore, when the user is performing multi-drum washing and all drums need water simultaneously, the program first determines whether each drum requires heating. If heating is required, this requirement is set as the highest priority in the water intake determination, and the number of drums requiring heating is determined. If only one drum requires heating, that drum is prioritized for water intake. If multiple drums require heating simultaneously, they are controlled to fill with water sequentially in ascending order of heating time. If no heating is required, the required water volume is set as the highest priority in the water intake determination, and the required water volumes of each drum are compared, controlling the drums to fill with water sequentially in ascending order of water volume. Furthermore, if two or more drums have the same required water volume, the remaining running time of each drum is compared, controlling the drums to fill with water sequentially in ascending order of remaining running time.

[0069] Furthermore, regardless of whether the user's habit is single-drum or multi-drum washing, in special cases, if the remaining running time, heating requirements, and required water volume of each washing drum are the same, then the number of times each washing drum is used within a certain time range, such as the number of times each washing drum is used within a month, is obtained, and the washing drum with the most usage is given priority in water intake. If the number of usages is still the same, then any washing drum is randomly controlled to have priority in water intake.

[0070] In step S32, the step of "controlling the water inlet sequence of each washing drum according to the number of washing drums" further includes:

[0071] When the number of washing drums is greater than 1, the washing drums with water pressure requirements are controlled to enter water sequentially according to the order specified by the user, and then the other washing drums are controlled to enter water simultaneously.

[0072] In the above steps, the water inlet sequence of each washing drum can be executed sequentially according to the user's specified order, meeting user needs and making it more user-friendly.

[0073] Referring to Figure 2 below, which is a possible complete flowchart of the water inlet control method for a multi-drum washing machine according to the present invention, the control method of the present invention includes the following steps when multiple drums need to be filled with water simultaneously:

[0074] S101, Obtain the current washing program of each washing drum that needs to be filled with water simultaneously;

[0075] S102, determine whether each washing drum has an inlet water pressure requirement based on the washing program;

[0078] S103, Obtain the number of washing drums with inlet water pressure requirements;

[0079] When the number of washing drums is equal to 1, proceed to step S104;

[0080] When the number of washing drums is greater than 1, proceed to step S105;

[0081] S104: First, control the water inlet of the washing drum that requires water pressure, and then control the water inlet of other washing drums at the same time;

[0082] S105, learns the user's washing habits;

[0083] If the user's washing habit is single-tub washing, then proceed to step S106;

[0084] If the user's washing habit is multi-tub washing, then proceed to step S107;

[0085] S106, first control multiple washing drums to enter water sequentially according to the sorted water inlet judgment conditions, and then control other washing drums to enter water simultaneously; wherein, the priority order of the water inlet judgment conditions is: the priority of the remaining running time of the washing drum is higher than the priority of the heating demand of the washing drum is higher than the priority of the required water volume of the washing drum.

[0086] S107, determine if the washing drum requires heating;

[0087] If so, proceed to step S108;

[0088] If not, proceed to step S120;

[0089] S108, Obtain the number of washing drums that require heating;

[0090] When the number of washing drums is equal to 1, proceed to step S109;

[0091] When the number of washing drums is greater than 1, proceed to step S110;

[0092] S109, first control the washing drum that requires heating to enter water first, and then control the other washing drums to enter water at the same time;

[0093] S110 first controls multiple washing drums to enter water sequentially according to the heating time required by the heating demand, and then controls other washing drums to enter water simultaneously;

[0094] S120: First, control multiple washing drums to enter water sequentially according to the sorted water inlet judgment conditions, and then control other washing drums to enter water simultaneously; wherein, the priority order of the water inlet judgment conditions is: the priority of the required water volume of the washing drum is higher than the priority of the remaining running time of the washing drum.

[0095] S130 controls the simultaneous water intake of multiple washing drums.

[0096] In addition, in step S103, when the number of washing drums is greater than 1, step S140 can also be executed.
