The intermittent working mode is sufficient to maintain the good state of the clothes without consuming additional energy to keep the device continuously running, thereby improving the overall energy efficiency. Due to the intelligent control of the device in the hosting mode, the working mode can be adjusted according to the actual needs of the clothes, such as appropriate temperature and humidity control. This not only prevents the clothes from being excessively dried and damaged by high temperature, but also maintains the color and material of the clothes and prolongs the service life of the clothes. The user can select the hosting mode according to his own living habits and needs. Whether the clothes are washed at night or when the user is out during the day, the user does not need to worry about the state of the clothes. The machine automatically enters the maintenance mode after completing the basic washing and drying function, reducing the user's subsequent worries about the state of the clothes. The control method is particularly suitable for use in regions with variable climates, which can automatically adjust the internal environment to ensure that the clothes can be kept in the best state regardless of changes in the external environment. The method provided in the embodiments is particularly suitable for use in environments with high temperature and humidity in summer or cold and dry environments in winter.

DETAILED DESCRIPTION

[0052] The terms "first", "second", "third", "fourth", and the like in the description and in the claims of the present application and above-mentioned drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the use of the terms so construed herein is merely for convenience and brevity and does not necessarily imply a serial or chronological order unless expressly so defined by the patentee. In addition, the terms "comprise", "comprising", "have", "having", "include", "including", "contain", "containing", and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, product, or apparatus that comprises, has, includes, contains a list of steps or elements does not necessarily comprise, have, include, or contain only those steps or elements but can include additional steps or elements not expressly listed or inherent to such process, method, product, or apparatus. The following will describe the technical solutions in the embodiments of the present application in a clear and complete manner with reference to the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0053] The operation mode of the conventional laundry treatment apparatus has some deficiencies, especially in terms of subsequent treatment of the laundry. Many users have the habit of washing laundry at night but taking out the laundry the next morning. Especially in summer or humid weather, due to the influence of high temperature and humidity, the laundry may be affected by re-moisture or odor generation due to long-time stay in the machine. These problems not only affect the use experience of the laundry, but also can cause damage to the material and color of the laundry.

[0054] Re-moisture is caused by the laundry absorbing moisture in the air after being dried in a high-humidity environment. In addition, high temperature and humidity are ideal conditions for the growth of bacteria and mold, which can cause the laundry to generate unpleasant odor or mold spots in the machine, bringing an unpleasant experience to the user. Therefore, simply stopping the machine completely at the end of the program without further measures to maintain the state of the laundry obviously cannot meet the needs of all users, especially in an environment with variable weather conditions.

[0055] In order to solve these problems, it is necessary to develop a laundry treatment apparatus control method capable of automatically adjusting the internal environment after the end of the washing and drying program to keep the laundry in an ideal state.

[0056] Referring to FIG. 1, the laundry treatment apparatus control method provided by the embodiments of the present application can specifically include:

[0057] S110, obtaining a laundry mode selection instruction and a hosting mode indication instruction;

[0058] Illustratively, the washing machine first receives a laundry mode selection instruction set by the user, which includes different washing programs such as normal washing, quick washing, and washing and drying integrated mode, etc.

[0059] Meanwhile, the washing machine also needs to obtain a hosting mode indication instruction. The hosting mode refers to the washing machine automatically performing subsequent operations when the user is not at home, such as automatically performing ventilation or heating after washing or drying is completed, so as to prevent clothes from being damp or having odor.

[0060] S120, when the washing mode selection instruction is a washing and drying mode instruction, and the hosting mode indication instruction indicates entering the hosting mode, the clothes processing device controls the washing motor 700, the circulating fan 400, the heating device 500, and the condensate valve 600 to work to perform the hosting of the dried clothes after ending the execution of the washing and drying mode instruction.

[0061] For example, if the user selects the washing mode as the washing and drying mode, and the hosting mode is also set as “on”, the washing machine will perform the hosting mode after the drying mode ends.

[0062] Referring to FIG. 10, in the hosting mode after the washing and drying mode, the washing machine controls the washing motor 700, the circulating fan 400, the heating device 500, and the condensate valve 600 to be periodically turned on and off as needed, so as to achieve the purpose of energy saving and maintaining the state of the clothes. The circulating fan 400 will be intermittently operated to maintain the appropriate temperature and humidity of the clothes, so as to prevent mildew or over-drying. The intermittent operation of the heating device 500 and the condensate valve 600 can help adjust the environment inside the washing machine, so as to ensure the optimal processing of the clothes in the hosting mode.

[0063] S130, when the washing mode selection instruction is a washing and drying mode instruction, and the hosting mode indication instruction indicates entering the hosting mode, the clothes processing device controls the washing motor 700 and the circulating fan 400 to work to perform the hosting of the dried clothes after ending the execution of the washing and drying mode instruction.

[0064] For example, when the washing mode selection instruction is the washing and drying mode instruction, once the washing machine completes the dehydration step, the washing machine automatically enters the hosting mode according to the previous setting of the user. In this mode, the washing motor 700 and the circulating fan 400 are alternately operated at intervals according to the predetermined rule.

[0065] The washing motor 700 and the circulating fan 400 are turned on and off according to the time interval set by the program. Such interval operation helps to maintain appropriate environmental conditions, reduces energy consumption, and at the same time ensures that the clothes are not damaged due to long-term stay in a humid and hot environment.

[0066] The intermittent start of the washing motor helps to redistribute the laundry, preventing it from staying in the same position for a long time and forming wrinkles or getting damp. The intermittent operation of the circulating fan 400 is used to regulate the air flow in the tub, helping to keep the environment dry and suitable inside the tub, preventing the growth of bacteria and mold.

[0067] Through the above steps, the hosting mode after the washing and drying mode of the laundry treatment device can effectively maintain the state of the laundry, especially in the case where the user cannot immediately take out the laundry. This intelligent control provides additional convenience and protection for the laundry, avoiding potential problems caused by environmental conditions such as dampness and odor. This demonstrates the advanced technology application of the laundry treatment device of the present application in improving user experience and operational convenience.

[0068] In summary, the laundry treatment device in the related art usually completely stops working after completing the washing and drying program or after the washing and drying program, which will cause a high temperature and humid or low temperature and humid environment, and it is easy to cause the laundry to return to moisture and odor in the high temperature and humid or low temperature and humid environment. The present embodiment sets the hosting mode so that the laundry treatment device can automatically switch to the operation of maintaining the state of the laundry after the drying mode ends. The present application controls the intermittent alternating operation of the circulating fan 400, the heating device 500 and the condensation valve 600 according to the predetermined rule, effectively preventing the laundry from returning to moisture due to the humid environment or breeding bacteria and mold due to the high temperature after staying in the machine for a long time. In the hosting mode of the present application, key components such as the washing motor 700, the circulating fan 400, the heating device 500 and the condensation valve 600 work intermittently rather than continuously, which greatly reduces energy consumption. The intermittent working mode is sufficient to maintain the good state of the laundry, without consuming additional energy to keep the device running continuously, thereby improving the overall energy efficiency. Due to the intelligent control of the device in the hosting mode, the working mode can be adjusted according to the actual needs of the laundry, such as appropriate temperature and humidity control. This not only prevents the over-drying and high-temperature damage of the laundry, but also maintains the color and material of the laundry, prolonging the service life of the laundry. Users can choose the hosting mode according to their own living habits and needs. Whether it is night washing or daytime outing, users do not need to worry about the state of the laundry. After completing the basic washing and drying function, the machine automatically enters the maintenance mode, reducing the user's subsequent worries about the state of the laundry. This control method is particularly suitable for areas with variable climate, which can automatically adjust the internal environment to ensure that the laundry can be kept in the best state regardless of the change of the external environment. The method proposed in the present embodiment is particularly suitable for use in high-temperature and humid summer or cold and dry winter environments.

[0069] In some examples, the above control of the intermittent operation of the washing motor 700, the circulating fan 400, the heating device 500 and the condensation valve 600 to perform the hosting mode includes:

[0070] controlling the above washing motor 700, the above circulating fan 400, the above heating device 500 and the above condensing valve 600 to be closed in a first time period;

[0071] controlling the above washing motor 700, the above circulating fan 400, the above heating device 500 and the above condensing valve 600 to work in a second time period;

[0072] controlling the above washing motor 700, the above circulating fan 400, the above heating device 500 and the above condensing valve 600 to be closed in a third time period;

[0073] after the above third time period, repeating the operations corresponding to the above second time period and the above third time period to perform the hosting of the drying clothes.

[0074] For example, in the first time period immediately after the end of the drying mode, the washing motor 700, the circulating fan 400, the heating device 500 and the condensing valve 600 are controlled to be closed. In the first time period, all the main operating components in the washing machine are in a non-working state to reduce energy consumption and prevent over-treatment of the clothes.

[0075] In the second time period, the washing motor 700, the circulating fan 400, the heating device 500 and the condensing valve 600 are controlled to work. At this time, these components will start to work to maintain the proper state of the clothes, such as removing moisture, maintaining appropriate temperature, and circulating air as needed.

[0076] In the third time period, the washing motor 700, the circulating fan 400, the heating device 500 and the condensing valve 600 are controlled to be closed again. This stage is similar to the first time period, the purpose is to put the device into sleep state again, so as to further save energy and prolong the service life of the device, and at the same time protect the clothes from being over-treated.

[0077] After the third time period, the clothes processing device will repeat the operation mode of the second time period and the third time period. This intermittent on-off cycle can continue until the user cancels the hosting mode or reaches the preset condition. Such a cycle operation helps to automatically adjust and protect the clothes when the user is not at home, while also avoiding waste of energy.

[0078] The clothes processing device can effectively utilize its core components to orderly start and close in different time periods in the hosting mode, thereby achieving the dual purposes of energy saving and clothes care. This intelligent control mechanism improves the user experience and operation efficiency of the washing machine, which is particularly suitable for the needs of modern life.

[0079] In some examples, the duration of the above first time period is less than the duration of the above third time period.

[0080] For example, the first time period is set to 30 minutes, the second time period is set to 10 minutes, and the third time period is set to 50 minutes. The first time period is relatively short compared to the third time period, allowing the laundry treatment device to quickly respond to the initial state of the laundry immediately after the program ends, especially when the laundry may still have a relatively high moisture content. This can quickly reduce the moisture content of the laundry and prevent issues such as re-moistening or odor caused by high humidity.

[0081] The longer third time period means that after an active drying or ventilation cycle, the machine will have a longer period of time to maintain the dryness of the laundry in a closed state. This arrangement helps to ensure that the laundry remains in good condition for a long time, reducing the problem of re-moistening or bacterial growth caused by environmental changes.

[0082] By shortening the first time period and lengthening the third time period, the overall energy consumption of the washer-dryer can be effectively controlled. The active phase of the components (i.e., the second time period) is short and concentrated, and the longer rest period of the third time period greatly reduces the overall energy consumption, achieving higher energy efficiency.

[0083] In the hosting mode, by setting a shorter first time period and a longer third time period, the working period of the machine can be more flexibly adjusted to adapt to different environmental and laundry state requirements. This periodic adjustment helps to more effectively maintain the state of the laundry, while also reducing the wear and tear of the device. The longer third time period helps to maintain the dryness and freshness of the laundry without the need for frequent activation of the device. This way is particularly beneficial for protecting the fibers and colors of the laundry, preventing damage to the laundry caused by frequent heating or over-drying.

[0084] In some examples, during the operation of the above-described washing motor 700, the above-described circulating fan 400, the above-described heating device 500, and the above-described condenser valve 600, the temperature of the incoming barrel is controlled to be between 45 degrees Celsius and 50 degrees Celsius.

[0085] For example, in the hosting mode operation, the washing motor 700, the circulating fan 400, the heating device 500, and the condenser valve 600 work intermittently as needed. During the operation of these components, it is particularly noted that the temperature of the incoming barrel is controlled to be between 45 degrees Celsius and 50 degrees Celsius.

[0086] This temperature range can ensure that the laundry is not damaged by excessive heat, while also being high enough to prevent re-moistening problems caused by low temperatures.

[0087] Maintaining the in-barrel temperature within this range is particularly crucial for preventing clothes from re-humidifying and controlling microbial growth. Temperatures between 45 and 50 degrees Celsius can effectively kill or inhibit the growth of bacteria and mold, which thrive in warm and humid environments. Additionally, this temperature range helps speed up the clothes drying process while maintaining energy efficiency, avoiding excessive energy consumption.

[0088] The temperature sensor built into the clothes treatment device continuously monitors the in-barrel temperature. Once it detects that the temperature deviates from the set range, the heating device will automatically adjust to restore it to between 45 and 50 degrees Celsius. The combined use of the circulating fan and the condensing valve also supports temperature stabilization, assisting in precise temperature control by adjusting air volume and condensing effects.

[0089] With this fine-grained temperature control strategy, the clothes treatment device not only provides efficient washing and drying effects but also automatically maintains the optimal state of clothes when the user is not present, reducing the risk of re-humidification and odor, and enhancing the overall user experience.

[0090] In some examples, controlling the washing motor and the circulating fan to perform the hosting of the drying clothes to perform the hosting of the drying clothes includes:

[0091] controlling the washing motor 700 and the circulating fan 400 to be off during a fourth time period;

[0092] controlling the washing motor 700 and the circulating fan 400 to be on during a fifth time period;

[0093] controlling the washing motor 700 and the circulating fan 400 to be off during a sixth time period;

[0094] after the sixth time period, repeating the fifth time period and the sixth time period intermittently to perform the hosting mode.

[0095] For example, during the fourth time period, the washing motor 700 and the circulating fan 400 are controlled to be off. The purpose of this stage is to let the machine enter a power-saving state, while reducing the mechanical action on the clothes, preventing the clothes from being damaged due to over-treatment.

[0096] During the fifth time period, the washing motor 700 and the circulating fan 400 are controlled to be on. The purpose of this stage is to help redistribute the clothes through the operation of the washing motor, avoiding long-term compression of the same position to form wrinkles or damage. At the same time, the start of the circulating fan helps to improve the air flow in the barrel, promoting drying and reducing humidity, thereby preventing clothes from re-humidifying or mildewing.

[0097] At the sixth time period, the washing motor 700 and the circulating fan 400 are again controlled to be turned off. The continuous off period in this stage helps to maintain energy efficiency while ensuring that the laundry maintains its state in an environment without continuous mechanical action.

[0098] After the end of the sixth time period, the laundry treatment apparatus will repeat the operation of the fifth and sixth time periods. This intermittent repetition mode helps to maintain the optimal state of the laundry over a longer period of time, especially in cases where the user cannot promptly take the laundry out of the laundry treatment apparatus.

[0099] Through the above intermittent control method, the laundry treatment apparatus can effectively regulate the in-machine environment in the hosting mode, preventing the laundry from being exposed to conditions that can cause damage for a long time. This intelligent control strategy not only improves energy efficiency, but also enhances the protection effect of the machine on the laundry, ensuring that the laundry remains in an ideal state before the user returns home, reducing the possibility of re-humidification and odor.

[0100] In one embodiment, the duration of the fourth time period is less than the duration of the sixth time period.

[0101] For example, the shorter off period of the fourth time period is intended to provide a short rest immediately after the laundry treatment apparatus has completed active washing or dehydration, reducing the energy consumption of the apparatus while preventing the laundry from re-humidifying due to long-term static placement.

[0102] The sixth time period is longer than the fourth time period, thereby providing longer stable protection to the laundry after a shorter active work, to ensure that the laundry maintains dryness and freshness for a long time without human supervision, avoiding the growth of bacteria or mold in the laundry in a high-humidity environment.

[0103] Through this setting, the laundry treatment apparatus can more effectively utilize energy in the hosting mode, while minimizing the damage that the laundry can suffer from environmental changes. The longer sixth time period allows the laundry to have more time to stabilize its state without active intervention, reducing the negative effects caused by temperature and humidity fluctuations.

[0104] In some examples, the above method further comprises:

[0105] During the operation of the above hosting mode, the above hosting mode is exited based on the user's touch operation on the panel or the remote instruction of the intelligent terminal.

[0106] For example, the hosting mode is automatically activated after the completion of the washing, dehydration or drying program, with the purpose of maintaining the optimal state of the laundry when the user is not at home, preventing the laundry from re-humidifying, developing odor or other potential quality problems.

[0107] In the hosting mode, the washing motor 700, the circulating fan 400, etc. can work intermittently according to the set time length, so as to maintain the suitable temperature and humidity in the drum.

[0108] The user can issue a command to exit the hosting mode at any time, either by directly touching the panel or remotely operating the intelligent terminal. It is considered that the user can go home in advance or needs to stop the hosting mode immediately for other reasons and manually handle the laundry. When the user chooses to exit the hosting mode, the laundry treatment device will immediately respond to the command and stop all activities in the hosting mode, such as the intermittent operation of the washing motor 700 and the circulating fan 400. This operation ensures that the user can quickly adjust the working mode of the machine according to the actual situation, improves the flexibility of the machine use and the satisfaction of the user.

[0109] In some examples, the above method further comprises:

[0110] In the case where the above hosting mode runs for more than a preset time length, the above hosting mode is exited.

[0111] For example, when the hosting mode is activated, the system sets a preset running time length of the hosting mode, which is based on the consideration of optimal laundry protection and energy efficiency. If the washing and drying machine runs in the hosting mode for reaching or exceeding the preset time length, the system will automatically perform the operation of exiting the hosting mode. This means that all components active in the hosting mode, such as the washing motor and the circulating fan, will stop working, and the machine state returns to the initial or standby state.

[0112] The preset time length can be set based on the average type, amount of laundry and possible environmental conditions (such as humidity, temperature). The preset time length is long enough to keep the laundry from being damaged when the user is not present, but the preset time length is not too long to avoid unnecessary energy consumption.

[0113] In some examples, the method proposed by the embodiments of the present application can be used in the laundry treatment device shown in FIGS. 2 to 4, which includes two circulation systems, i.e., a large circulation system and a regeneration circulation system.

[0114] The large circulation system is used to bring the humid air in the drum to the regeneration circulation. In the large circulation system, the dry and high-temperature gas enters the washing cylinder 112 through the washing cylinder air inlet 101, removes the moisture on the laundry in the cylinder, and generates humid gas. The humid gas passes through the outer cylinder air duct 114 to the outer cylinder circulating fan interface 115 and then enters the circulating fan air duct 109 to the molecular sieve carousel 110. In the molecular sieve carousel, the humid gas is dried to become dry air, and then reenters the washing cylinder air inlet 101. The circulating fan 108 of the large circulation is responsible for pushing this process.

[0115] The wet and hot air for absorbing the molecular sieve in the regeneration circulation system is then discharged. In the regeneration circulation system, the wet and hot air first enters the condenser 103 through the condenser air inlet 1031. In the condenser, the wet and hot air is condensed and dried to become dry and low-temperature air, which is then pushed into the drying heating pipe 106 by the regeneration fan 104. The air heated by the drying heating pipe reaches the molecular sieve rotating disc 110 again, and after completing the moisture absorption process, the air is pushed back to the condenser air inlet 1031 by the regeneration fan to complete the circulation. The rotation of the rotating disc is driven by the rotating disc motor 111 to ensure that the rotating disc is uniformly heated and regenerated.

[0116] In other examples, the method proposed in the embodiments of the present application can be used in the laundry treatment device as shown in FIGS. 5-6, which includes a hot drying system 602.

[0117] The hot drying system 602 includes a drying channel in which devices for electric heating such as electric heating wires, electric heating discs, electric heating pipes, etc. are arranged. The laundry treatment device shown in FIGS. 5-6 uses air flowing through the drying channel to heat the laundry, and then discharges the wet and hot air generated by heating the laundry from the laundry treatment device to form a cycle, thereby continuously removing the moisture from the laundry to achieve the purpose of drying the laundry.

[0118] In some embodiments, the laundry treatment device shown in FIGS. 5-6 uses air flowing through the drying channel to heat the laundry, and then discharges the wet and hot air generated by heating the laundry through a condensing system to condense the moisture into water and collect it in a water storage box to form a cycle, thereby continuously removing the moisture from the laundry to achieve the purpose of drying the laundry.

[0119] It should be noted that the laundry treatment device shown in FIGS. 5 and 6 can also operate the steps of the method corresponding to any of the embodiments of the present application.

[0120] The laundry treatment device can apply the two hosting modes proposed in the embodiments of the present application to maintain the state of the laundry after washing and drying according to different user needs and operating environments.

[0121] After the dehydration process, the laundry is usually quite wet. When entering the hosting mode, the laundry treatment device redistributes and ventilates the laundry by intermittently starting the washing motor and the circulating fan, thereby preventing the formation of wrinkles and the generation of odors or mold caused by a humid environment. The built-in temperature and humidity sensor monitors the internal environment, and adjusts the frequency and duration of the operation of the fan according to the state of the laundry to keep the internal environment dry and suitable, thereby avoiding the laundry being in an unsuitable environment for a long time.

[0122] In the post-drying hosting mode, after the clothes are dried, if the user does not take out the clothes from the clothes treatment device in time, the machine will automatically enter the hosting mode to maintain the state of the clothes until the user operates. The post-drying clothes may continue to release heat due to high temperature, and the machine controls the temperature in the drum by intermittently adjusting the operation of the internal fan (circulating fan) to prevent the clothes from being damaged due to excessive temperature or problems caused by a humid environment. Especially in humid or variable climates, post-drying clothes are prone to re-moisture. The hosting mode adjusts the air duct and temperature to ensure that the clothes remain in a suitable dry state and reduce problems caused by moisture.

[0123] It should be noted that the method proposed in the embodiments of the present application is not only applicable to the clothes treatment device with the molecular sieve rotating disc described above, but also applicable to other clothes treatment devices with drying duct heating or other dehumidification modes.

[0124] As shown in FIG. 7, it is an effect diagram of a control panel of a clothes treatment device according to an embodiment of the present application.

[0125] In some examples, the method further includes:

[0126] When the hosting mode indication instruction indicates waiting for hosting, the power light, the start-stop light, the unlock light, and the hosting light icon of the control panel in the clothes treatment device are controlled to be always on, and other lights in the control panel are controlled to be off;

[0127] When the hosting mode indication instruction indicates entering hosting, the power light, the start-stop light, the unlock light, and the hosting light of the control panel in the clothes treatment device are controlled to be always on, and other lights in the control panel are controlled to be off.

[0128] For example, when the hosting mode indication instruction indicates "waiting for hosting", the power light is always on, indicating that the device is in a powered-on and available state. The start-stop light is always on, indicating that the current device can be started or stopped, but has not yet entered the formal operation process, prompting that the clothes treatment device is ready to accept subsequent operations. The unlock light is always on, indicating that the current door lock is in a locked state (such as the washing machine door or hatch is currently closed), or the user can unlock by clicking the icon corresponding to the unlock light. The hosting light clearly prompts that the current device is in the stage of waiting for hosting through flashing. Other lights are off to avoid conflicts with the hosting mode related indicators, reduce unnecessary interference, and highlight the most important state information.

[0129] The "waiting for hosting" state often indicates that the device is ready, but has not yet been actually taken over by the external hosting party. At this time, the power light, the start-stop light, and the unlock light are always on, which can let the user or the hosting party know that the device is in a "available and waiting" state; the hosting light icon flashes to further prompt the "waiting for hosting" state.

[0130] When the hosting mode instruction indicates "enter hosting", the power light is always on, indicating that the device remains powered on, and the basic power of the device is not disconnected. The start-stop light is always on, indicating that operations such as starting or pausing can be performed during the hosting process. The unlock light is always on, indicating that the current door lock of the device can also be unlocked / locked. The hosting light is always on, which is different from the "hosting light icon flashing" in the "waiting for hosting" stage described above. Here, the always-on indicates that the device has truly entered the hosting state, prompting "controlled by an external management party" or "the device is in the hosting process". Other lights are turned off, and only the indicator lights related to the hosting state are retained to avoid confusion.

[0131] The method provided in this embodiment is around the "waiting for hosting" stage and the "entering hosting" stage in the "hosting mode", and the indicator lights of the clothes treatment device control panel are set and managed in a targeted manner. Through the flexible combination of the power light, the start-stop light, the unlock light, the hosting light icon, and the distinction of their flashing / always-on / off states, the hosting stage and the running status of the clothes treatment device can be quickly conveyed visually. This not only improves the operation efficiency and safety of the user and the hosting party, but also provides basic support for realizing more intelligent and unmanned clothes treatment devices.

[0132] In some examples, the above method further comprises:

[0133] obtaining current time information;

[0134] when the above-mentioned current time information corresponds to night, after entering the hosting mode for a preset hosting duration, turning off all indicator lights;

[0135] when the above-mentioned current time information corresponds to day, obtaining user display light setting information;

[0136] after entering the hosting mode for a preset hosting duration, controlling whether all indicator lights are turned off based on the user display light setting information.

[0137] Illustratively, in the hosting mode, the clothes treatment device will usually light up the corresponding indicator lights (such as the power light, the start-stop light, the unlock light, the hosting light, etc.) according to the device state. However, when the device is in the hosting mode for a long time, the continuous lighting of the indicator lights may cause the following problems: the continuous lighting of the indicator lights will accumulate a certain amount of energy consumption; if the indicator lights are always on at night or during the user's sleep period, it may disturb the user; some users want to reduce the lighting as much as possible during the day to save energy or reduce light stimulation; other users want to keep a certain amount of light prompts to facilitate checking the device status at any time.

[0138] To solve the above problems, the embodiment introduces the features of "acquiring current time information" and "user display lamp setting information", balances between meeting the night light-off demand and respecting user's personalized settings, and realizes more intelligent light control.

[0139] The current time information acquisition device can be a built-in clock chip or accurately acquire local time from a server through networking. The system determines whether it is currently at night according to the set time threshold (for example, 22:00-7:00 is considered night; 7:00-22:00 is considered day). For example, if the current time is 23:30, it is determined to be "night"; if the current time is 15:00, it is determined to be "day".

[0140] The preset hosting duration of the hosting mode can be understood as a timing threshold. For example, it can be set to 2 minutes. After the device switches to the hosting mode, if it is in the hosting mode for the preset hosting duration and no one operates or no new instruction is input, the light will be turned off or other operations will be triggered after the preset hosting duration of the hosting mode is exceeded. For example, setting the preset hosting duration of the hosting mode to 2 minutes means that when the device enters hosting, if there is no further operation or event within 2 minutes, the system will execute the next logical step (turn off the light or control based on user settings).

[0141] When it is determined through time that the current time is at night, after entering the preset hosting duration of the hosting mode, the system will turn off all indicator lights. This can avoid the possible interference of long-time light on in the night on the user's rest. In the night, there is usually less external interference, and the user does not often check the device status, so turning off the light can effectively save power.

[0142] When it is determined through time that the current time is at day, after entering the preset hosting duration of the hosting mode, the system first acquires the user display lamp setting information, and then decides whether to turn off the light according to the user's preference.

[0143] The user can set the preference through the device panel, mobile phone App or background system: option A: turn off all indicator lights in the hosting mode even during the day; option B: keep some indicator lights on in the hosting mode during the day (for example, the power light), so as to confirm that the device is in the hosting state at any time; option C: keep all indicator lights on in the hosting mode during the day; or a more detailed light management strategy can be set.

[0144] If the user chooses to turn off all indicator lights after a certain duration in the day, the system will turn off all indicator lights after the certain duration is exceeded; if the user chooses to keep some indicator lights, the system will only turn off the lights that are not related to the hosting state, and keep the specified lights on or flashing; if the user chooses to keep all indicator lights on, the system will still maintain the original light state and not perform the light-off process.

[0145] The embodiment in the hosting mode realizes the functions of automatic light-off at night, flexible light-off or light reservation based on user preference in the daytime, by acquiring current time information, displaying light setting information to the user, and combining the timing strategy of preset hosting duration. The scheme can meet the requirements of the environment at night (such as energy saving and avoiding light pollution), and take into account the use preference of different users for the indicator light in the daytime, thereby further improving the intelligence and user experience of the clothes treatment equipment.
