BRIEF DESCRIPTION OF DRAWINGS

[0017] The preferred embodiments of the present application will be described below with reference to the accompanying drawings, in which:

[0018] Figure 1 is the main step flowchart of the heating control method of the multi-cylinder washing machine of the present application;

[0019] Figure 2 is a possible complete step flowchart of the heating control method of the multi-cylinder washing machine of the present application. DETAILED DESCRIPTION

[0020] 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.

[0021] 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.

[0022] The washing machine of this invention includes at least two washing drums, each capable of independent heating and independent operation of a washing program. The heating method for each washing drum is either steam heating or hot air heating. Steam heating involves an electric heating element installed at the bottom of the washing drum, which heats the washing water at the bottom of the drum to generate steam. Hot air heating involves a drying system that supplies hot air into the washing drum. The drying system is a heat pump drying system and / or an electric heating drying system. The heat pump drying system includes a fan, a compressor, an evaporator, and a condenser. Air is heated as it passes through the condenser and then delivered to the inner drum. Adding an electric heating drying system to the heat pump drying system can improve the heating rate. The washing machine of this invention can be a drum washing machine or a top-loading washing machine. The control method of this invention is described below using a drum washing machine as an example.

[0023] First refer to Figure 1 The figure is a flowchart of the main steps of the heating control method for the multi-drum washing machine of the present invention. Figure 1 As shown, when the heating processes of multiple washing drums overlap and the interval between the heating start times of each washing drum is less than or equal to a set threshold, the control method of the present invention includes:

[0024] S1, determine if there is a washing drum that did not execute the heating program last time;

[0025] S2, if there is at least one, first control the washing drum that is not in the last heating program to execute the heating program, and then control the other washing drums to execute the heating program. For the washing drum that is not in the last heating program and the other washing drums: determine the heating order according to the set temperature of the washing program corresponding to each washing drum and heat multiple washing drums.

[0026] S3, if not present, determines the heating sequence based on the set temperature of the washing program corresponding to each washing drum and heats multiple washing drums.

[0027] In some embodiments, the case where the interval between the start times of multiple washing drums is less than or equal to a set threshold includes cases where the start times of multiple washing drums are the same or different.

[0028] In step S1, "determining whether there is a washing drum that is not the last to execute the heating program" specifically refers to determining whether there is a washing drum with segmented heating. Specifically, segmented heating means that the washing drum has heating requirements during both the washing and / or rinsing programs, and that heating requirements exist in multiple washing stages of the washing program and / or multiple rinsing stages of the rinsing program.

[0029] In step S2, to ensure overall washing efficiency, if a washing drum is not the last to execute a heating program, it indicates that this washing drum has a heating requirement in addition to the current heating requirement, meaning it requires segmented heating. In this case, the washing drum is heated first, followed by the other washing drums that do not require segmented heating. If multiple washing drums require segmented heating and multiple washing drums do not, the heating order is determined based on the set temperature of the washing program for each washing drum.

[0030] In step S3, if there are no multiple washing drums that require segmented heating, then the heating sequence is determined according to the set temperature of the washing program corresponding to each washing drum.

[0031] The control method of the present invention further includes:

[0032] S4, obtain the historical usage count of each washing drum;

[0033] S5, compare multiple differences between the historical usage counts of one washing drum and the historical usage counts of other washing drums;

[0034] The steps for "determining whether there is a washing drum that did not execute the heating program last time" specifically include:

[0035] S6. When at least one of the multiple differences is less than the set number, determine whether there is a washing drum that did not execute the heating program last time.

[0036] S7. When multiple differences are greater than or equal to the set number of times, first control the washing drum with multiple differences greater than or equal to the set number of times to execute the heating program, and then control the other washing drums to execute the heating program. For the other washing drums: continue to compare the multiple differences between the historical usage count of one washing drum and the historical usage count of the other washing drums.

[0037] In step S4, the control system records the number of times each washing drum is used after each use. The historical usage count of each washing drum can be the number of times it is used within a preset time period, which can be within the past month, the past year, or the cumulative number of times it has been used since the first use.

[0038] In some embodiments, the washing machine with the highest user preference can be determined based on the difference between the historical usage counts of each washing drum. For example, suppose two washing drums need to be heated simultaneously, denoted as drum A and drum B. If the historical usage count of drum A is greater than or equal to a set number compared to the historical usage count of drum B, then drum A is the washing machine with the highest user preference. Therefore, drum A is controlled to execute the heating program first, followed by drum B. Now suppose three washing drums need to be heated simultaneously, denoted as drum A, drum B, and drum C. If the historical usage count of drum A is greater than or equal to a set number compared to the historical usage counts of both drums B and C, then drum A is the washing machine with the highest user preference. Therefore, drum A is controlled to execute the heating program first, followed by drums B and C. Regarding the heating order between drums B and C, their historical usage counts are then compared. If the difference in usage counts is greater than or equal to a set number of times, and if the historical usage counts of tub B are greater than or equal to the set number of times tub C is used, then tub B is controlled to execute the heating program first, followed by tub C. If the historical usage counts of tub B are less than the set number of times tub C is used, then it is determined whether there is a tub that did not execute the heating program last time. Assuming there are three tubs that need to be heated simultaneously, denoted as tub A, tub B, and tub C, if the historical usage counts of tub A are greater than or equal to the set number of times tub B is used, but less than the set number of times tub A is used compared to tub C, it indicates that the tub with the highest user preference cannot be determined, and therefore it is determined whether there is a tub that did not execute the heating program last time.

[0039] The control method of the present invention further includes:

[0040] S8, before obtaining the historical usage count of each washing drum, first determine whether there is a user-specified heating sequence;

[0041] S9, if present, heats multiple washing drums according to the user-specified heating sequence.

[0042] In step S9, the step of "heating multiple washing drums according to the heating order specified by the user" specifically includes: obtaining the heating order specified by the user through voice interaction or interface interaction; and heating multiple washing drums according to the heating order specified by the user.

[0043] In some embodiments, voice interaction allows users to directly set the heating order of multiple washing tubs via voice commands, such as "Heat the upper tub first," "Heat the lower tub first," or "Heat the upper tub first, then the lower tub." Alternatively, voice guidance can be provided to the user beforehand, and the heating order of the multiple washing tubs can be set based on the user's voice response. For example, the user can be asked, "Do you want to set the heating order?" or "Do you want to heat the upper tub first?" Voice interaction methods that provide pre-set voice guidance typically offer this guidance before the heating program begins or before the entire washing program starts, ensuring proper operation. Interface interaction methods typically involve displaying a pop-up reminder on the user interface before the heating program begins or before the entire washing program starts, allowing the user to set the heating order based on the pop-up reminder.

[0044] It should be noted that the voice interaction method, where users set parameters directly via voice commands, can be performed at any time during the entire washing cycle. If the washing machine has already determined the heating order and a washing drum is currently executing its heating program, and the user attempts to change the heating order via voice at this time, the user will be prompted that the heating order cannot be changed. Furthermore, if the user simultaneously uses both voice and interface interaction to set the heating order, the command will be overridden, with the later command taking precedence. Of course, this is not a limitation; the art can also, as needed, prioritize the earlier command. Specific operations can be set according to actual circumstances, and all such adjustments are within the scope of this invention.

[0045] In the above steps, the heating 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.

[0046] In steps S2 and S3, the step of "determining the heating sequence and heating multiple washing drums according to the set temperature of the washing program corresponding to each washing drum" specifically includes:

[0047] S21, obtain the set temperature of the washing program corresponding to each washing drum;

[0048] S22, determine the heating sequence of multiple washing drums according to the set temperature;

[0049] S23 controls multiple washing drums to execute the heating program in the heating sequence.

[0050] In step S21, the washing program refers to the washing program selected by the user according to washing needs, such as "Smart Wash" or "Hot Clean". The set temperature refers to the actual set temperature corresponding to the selected washing program in the washing drum. Specifically, different washing programs have multiple temperature settings pre-stored. Generally, when a user selects a washing program, it will automatically default to a certain temperature setting. Of course, the user can also select a temperature setting as needed. For example, if the user selects the "Smart Wash" washing program, the default set temperature of this washing program is 30℃. If the user directly defaults to the set temperature of this washing program, then the set temperature obtained in step S311 is 30℃. If the user selects the highest temperature setting of the washing program, 80℃, during actual washing, then the set temperature obtained in step S21 is 80℃.

[0051] In step S22, the step of "determining the heating sequence of multiple washing drums according to the set temperature" specifically includes:

[0052] S221, when the set temperature of multiple washing drums is not the highest set temperature of the corresponding washing program, control the multiple washing drums to execute the heating program according to the heating judgment conditions;

[0053] Heating determination criteria include:

[0054] At least one of the remaining time and the required water intake.

[0055] "Remaining time" can refer to the remaining running time of the entire washing program, or the remaining heating time of the entire washing program. "Required water volume" refers to the total water volume required for the entire washing program.

[0056] The step where the heating determination condition is the remaining time specifically includes:

[0057] Get the remaining time for each washing drum;

[0058] The heating sequence of the multiple washing drums is based on the remaining time, from smallest to largest.

[0059] The steps for determining the required inlet water volume based on the heating criteria specifically include:

[0060] Obtain the required water intake for each washing drum;

[0061] The heating sequence of multiple washing drums is based on the required water volume, from smallest to largest.

[0062] In step S22, the step of "determining the heating sequence of multiple washing drums according to the set temperature" further includes:

[0063] S222: When the set temperature of at least one washing drum is the highest set temperature of the corresponding washing program, control multiple washing drums to execute an alternating heating program.

[0064] In step S222, when at least one washing drum has a set temperature that is the highest set temperature of the corresponding washing program, i.e., the user selects the highest temperature setting of the corresponding washing program as needed, the program determines that the user has a strong desire to sterilize the washing drum. Therefore, by using multiple washing drums to alternate heating programs, the program can maintain a high temperature inside the washing drum for a long time.

[0065] The alternating heating program is as follows:

[0066] Multiple washing drums are heated alternately for a certain time interval until each washing drum has finished heating. Specifically, the multiple washing drums are heated alternately for a certain time interval. After each time interval, it is determined whether there is only one washing drum that has not finished heating. If so, the washing drum that has not finished heating is controlled to continue heating until the end. If not, the multiple washing drums are controlled to continue heating alternately.

[0067] Example 1: Suppose there are two washing drums that need to be heated simultaneously, and the set temperature of both washing drums is the highest set temperature for the corresponding washing level. Then, the two washing drums will be heated alternately to the set temperature.

[0068] Example 2: Suppose there are two washing drums that need to be heated simultaneously, and the set temperature of one washing drum is the highest set temperature of the corresponding washing program, while the set temperature of the other washing drum is a non-highest set temperature of the corresponding washing program. Then, the two washing drums will heat alternately. When the set temperature of one washing drum is reached, the other washing drum will directly heat to its corresponding set temperature.

[0069] Example 3: Suppose there are three washing drums that need to be heated simultaneously, and the set temperature of two of the washing drums is the highest set temperature of the corresponding washing program, while the set temperature of the other washing drum is a non-highest set temperature of the corresponding washing program. Then, the three washing drums will first heat alternately. When the set temperature of one of the washing drums is reached, the other two washing drums will continue to heat alternately until the set temperature is reached.

[0070] Example 4: Suppose there are three washing drums that need to be heated simultaneously, and the set temperature of two of the washing drums is the non-maximum set temperature of the corresponding washing program, while the set temperature of the other washing drum is the maximum set temperature of the corresponding washing program. Then, the three washing drums will heat alternately. When the set temperature of two of the washing drums is reached, the other washing drum will directly heat to its corresponding set temperature.

[0071] It should be noted that, in this embodiment, the execution logic for determining the heating order of the multiple washing drums based on the remaining time and required water volume, and the execution logic for interleaved heating based on the corresponding washing program settings, are independent of each other; that is, they have no logical relationship. In practical applications, those skilled in the art can select at least one of them to execute the heating program according to actual needs. For example, when multiple washing drums have heating requirements simultaneously, they can be controlled to execute the heating program sequentially according to the remaining time from least to most, or sequentially according to the required water volume from least to most, or they can be controlled to heat alternately.

[0072] In a preferred embodiment, there is also a logical relationship between the three execution logics mentioned above: the set temperature of the washing program corresponding to each washing drum is obtained; when the set temperature of multiple washing drums is not the highest set temperature of the corresponding washing program, the multiple washing drums are controlled to execute the heating program according to the heating judgment condition; when the set temperature of at least one washing drum is the highest set temperature of the corresponding washing program, the multiple washing drums are controlled to execute the alternating heating program.

[0073] Specifically, in step S221, the step of "controlling multiple washing drums to execute the heating program according to the heating determination conditions" includes:

[0074] S2211, obtain the user's washing habits;

[0075] S2212, prioritize the heating determination conditions according to the user's washing habits;

[0076] S2213 controls multiple washing drums to heat according to the ordered heating conditions.

[0077] Furthermore, in step S2212, the step of "prioritizing the heating determination conditions according to the user's washing habits" specifically includes:

[0078] If the user's washing habit is single-drum washing, the heating determination conditions are prioritized as follows: the remaining time has a higher priority than the required water volume.

[0079] If the user's washing habit is multi-drum washing, the priority of the heating determination condition is ranked as follows: the priority of the required water intake is higher than the priority of the water intake required for the remaining time.

[0080] Specifically, if the 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 heated simultaneously, the program first compares the remaining time of each drum and controls each drum to execute the heating cycle in ascending order of remaining time. Furthermore, if multiple drums have the same remaining time, the program then determines the required water volume for each drum and controls each drum to execute the heating cycle in ascending order of required water volume.

[0081] If the user's washing habit is multi-drum washing, the program defaults to using the most efficient washing standard for multi-drum washing. Therefore, when the user is performing a multi-drum wash and all drums need heating simultaneously, the program first determines the required water volume for each drum and controls each drum to execute the heating program sequentially in order of increasing water volume. Furthermore, if multiple drums require the same amount of water, the program compares the remaining time for each drum and controls each drum to spin-dry sequentially in order of increasing remaining time.

[0082] Furthermore, regardless of whether the user prefers single-drum or multi-drum washing, in special circumstances, if the remaining time and required water volume of each washing drum are the same, 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 prioritized for heating. If the number of usages is still the same, any washing drum is randomly selected for priority heating.

[0083] The following reference Figure 2 This figure is a possible complete flowchart of the heating control method for a multi-drum washing machine according to the present invention. Figure 2 As shown, when multiple washing drums need to be heated simultaneously, the control method of the present invention includes:

[0084] S101, Determine if a user-specified heating sequence exists;

[0085] If it exists, proceed to step S102;

[0086] If it does not exist, proceed to step S103;

[0087] S102, heating multiple washing drums according to the heating sequence specified by the user;

[0088] S103, Obtain the historical usage count of each washing drum;

[0089] S104, compare multiple differences between the historical usage counts of one washing drum and the historical usage counts of other washing drums;

[0090] If at least one of the multiple differences is less than the set number, then step S105 is executed;

[0091] When multiple differences are all greater than or equal to the set number of times, step S130 is executed;

[0092] S105, determine whether there is a washing drum that did not execute the heating program last time;

[0093] If so, proceed to step S106;

[0094] If not, proceed to step S107;

[0095] S106, first control the washing drum that is not in the last heating program to execute the heating program, and then control the other washing drums to execute the heating program; for the washing drum that is not in the last heating program and other washing drums: execute step S107;

[0096] S107, Obtain the set temperature of the washing program corresponding to each washing drum;

[0097] When the set temperature of multiple washing drums is not the highest set temperature of the corresponding washing program, step S108 is executed;

[0098] When at least one washing drum has a set temperature that is the highest set temperature for the corresponding washing program, step S120 is executed.

[0099] S108, learns the user's washing habits;

[0100] If the user's washing habit is single-tub washing, then proceed to step S109;

[0101] If the user's washing habit is multi-tub washing, then proceed to step S110;

[0102] S109, control multiple washing drums to be sorted according to the priority of heating judgment conditions as follows: the priority of remaining time is higher than the priority of required water volume, and the heating program is executed in sequence.

[0103] S110, control multiple washing drums to be sorted according to the priority of heating judgment conditions: the priority of the required water volume is higher than the priority of the required water volume for the remaining time, and execute the heating program in sequence.

[0104] S120 controls multiple washing drums to perform an alternating heating program;

[0105] S130: First, control multiple washing drums whose differences are all greater than or equal to a set number of times to execute the heating program, and then control other washing drums to execute the heating program. For other washing drums: execute step S104.

[0106] In summary, in the preferred embodiment of the present invention, it is determined whether there is a washing drum that is not the last to execute the heating program; if at least one exists, the washing drum that is not the last to execute the heating program is controlled to execute the heating program first, and then the other washing drums are controlled to execute the heating program; if none exists, the heating sequence is determined according to the set temperature of the washing program corresponding to each washing drum, and multiple washing drums are heated. The present invention can avoid power overload on the entire washing machine, while controlling the heating sequence of multiple washing drums to avoid heating conflicts between them, ensuring washing effect. Furthermore, by prioritizing the control of washing drums with segmented heating requirements, washing efficiency is improved, and user needs are met.
