Clothes processing device and control method thereof

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on Chinese patent application number 202310780989.1, filed on June 28, 2023, Chinese patent application number 202311151556.6, filed on September 6, 2023, and Chinese patent application number 202322431962.X, filed on September 6, 2023, and claims priority to the above three Chinese patent applications. The entire contents of the above three Chinese patent applications are hereby introduced into this application as a reference. Technical Field

[0003] The present application relates to the technical field of clothing processing, and in particular to a clothing processing device and a control method thereof. Background Art

[0004] Clothes processing equipment is one of the common appliances in daily life. In the related art, the clothes processing equipment cleans the clothes indiscriminately by soaking and washing the clothes in a clothes holding chamber, and the cleaning effect of local stains on the clothes is poor.

[0005] The current way of cleaning clothes with clothing treatment devices is generally to inject foam into the clothing chamber after the user randomly places the clothes into the clothing chamber, and then evenly soak the clothes with foam to clean the clothes as a whole. If there is a heavier stain on the clothes, the cleaning effect of this part of the stain is poor. If a better cleaning effect is needed for this part of the heavier stain, a large amount of foam will be wasted. As for another possible treatment method, the user can pre-treat this part of the heavier stain in advance, for example, by manually cleaning this part of the heavier stain, and then clean the whole piece of clothing with the clothing treatment device. Although this treatment method can save foam or detergent, it undoubtedly greatly affects the user experience.

[0006] It should be noted that the solutions described in this section are for a clearer understanding of the present application and are not acknowledged as prior art by being included in this section. Unless otherwise stated in the present application, the solutions described in this section are not prior art for the present application.

[0007] Summary of the Invention

[0008] In view of this, the present application hopes to provide a clothing processing device and a control method thereof that can improve local cleaning ability.

[0045] In some embodiments, generating stain placement prompt information includes:

[0046] Confirm to start the foam cleaning program and generate a stain placement prompt.

[0047] The technical solution provided by this application has the following advantages compared with the existing technology:

[0048] The present application provides a method for controlling a laundry treatment device, the method comprising: generating a stain placement prompt to instruct a user to place at least a portion of a stained area of ​​a garment in a foam delivery area within a garment chamber; and controlling the laundry treatment device to deliver foam to at least a portion of the stained area of ​​the garment. Based on the above scheme, the present application can prompt a user to place at least a portion of a stained area of ​​the garment, particularly a heavily stained area, within a specific foam delivery area, and deliver foam to that portion of the garment. The foam can then directly and fully contact the heavily stained area to clean the heavily stained portion, allowing the delivered foam to fully penetrate the heavily stained portion of the garment, allowing the active substances in the foam to decompose the stains within the heavily stained portion. Compared to the prior art method of randomly placing garments in a garment chamber, injecting foam into the chamber, and then evenly soaking the garment with the foam to clean the entire garment, the foam in the present embodiment can be concentratedly sprayed onto the heavily stained portion of the garment, increasing the amount of foam acting on the localized stain and the duration of its action, thereby enhancing the stain removal effect. Consequently, the stain removal effect on at least a portion of the stained area of ​​the garment is improved. Compared to the prior art method of injecting a large amount of foam to evenly spray all areas of clothing with foam and remove even heavier stains, the embodiments of the present application can reduce the amount of foam used. In addition, under the premise of adopting the control method of the clothing treatment device provided by the present application, the user only needs to place the heavier stains in the foam delivery area according to the prompts. Compared with the manual cleaning method that pre-treats at least part of the stained area, the user's operation process is greatly reduced and the user experience is improved.

[0059] In the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other. The detailed description in the specific implementation method should be understood as an explanation of the purpose of this application and should not be regarded as an improper limitation on this application.

[0060] In order to more clearly understand the above-mentioned objectives, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0061] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0062] It should be noted that down refers to the direction of the ground, and up is the direction opposite to down; front refers to the direction toward the user, and back is the direction opposite to front; left refers to the direction of the left hand side when the user is at the front, and right is the direction opposite to left. The up and down directions, the front and back directions, and the left and right directions together constitute a three-dimensional vertical coordinate system that is perpendicular to each other. In the embodiments of the present application, the orientations or positional relationships of "up", "down", "front", "back", "left", and "right" are based on the orientations or positional relationships shown in Figures 1 to 5. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application. The present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0063] Referring to Figures 1 to 3, an embodiment of the present application provides a clothing processing device, which includes a clothing receiving chamber 1a, an indicating device 2 and a dispensing device 3.

[0064] The clothing chamber 1a is used for placing and processing clothing.

[0065] The indicating device 2 is used to indicate a placement area 2a in the clothing storage chamber 1a. For example, the indicating device 2 can indicate a portion of the clothing storage chamber 1a as the placement area 2a, and local stains on the clothing may be located in the placement area 2a.

[0066] The dispensing device 3 is used to dispense a cleaning agent into the dispensing area 2a. The cleaning agent is used to clean stains in the dispensing area 2a. The dispensing device 3 dispenses the cleaning agent into the dispensing area 2a to clean local stains on the clothes in the clothing chamber 1a, thus providing the clothing treatment device with a cleaning function.

[0067] Exemplarily, the laundry treatment device uses a cleaning agent and cleans the laundry in a non-immersion manner. The non-immersion manner means that there is no liquid water immersion. Exemplarily, the cleaning agent enters the laundry chamber 1a to clean the laundry, and during this process, the laundry is not soaked by liquid water.

[0068] In the related art, uniformly spraying the cleaning agent on the whole is not effective in cleaning local stains on clothes, and increasing the amount of cleaning agent used overall will lead to problems such as prolonged time and incomplete removal of residual cleaning agent.

[0069] The clothing processing device provided in the embodiment of the present application uses an indicating device 2 to indicate a placement area 2a in the clothing holding chamber 1a. The placement area 2a is an area indicating that the user can place local stains on the clothing. For example, the user can place the local stains on the clothing in the placement area 2a, and then use the placement device 3 to place the cleaning agent in the placement area 2a to clean the stains on the clothing to be processed in the placement area 2a. In this way, the amount of cleaning agent in the placement area 2a is increased by locally and concentratedly placing the cleaning agent. The cleaning agent in the remaining areas of the clothing holding drum 1 that are not indicated as the placement area 2a (for example, outside the placement area 3a) can be less or no cleaning agent relative to the placement area 2a, so that deep cleaning of local stains on the clothing can be achieved. In this way, the cleaning effect of local stains can be improved, and the problems of prolonged time for removing residual cleaning agent and incomplete removal caused by the overall increase in the amount of cleaning agent can be avoided.

[0070] The composition of the cleaning agent is not limited. For example, the cleaning agent can clean clothes by contacting with the stains to desorb the stains. The cleaning agent can be an organic solvent that can effectively remove stains, etc.

[0071] The specific type of clothing processing equipment is not limited. For example, clothing processing equipment includes but is not limited to clothing care cabinets, dryers, washing machines or washing and drying machines, etc.

[0072] In some embodiments, the clothing chamber 1a is non-rotatable. In other words, the clothing chamber 1a remains fixed. During the clothing processing process, the clothing chamber 1a remains stationary. For example, if the clothing processing device is a clothing care cabinet, the clothing chamber 1a of the clothing care cabinet is non-rotatable.

[0073] Exemplarily, the clothing processing device is a cabinet-type clothing processing device. Specifically, the clothing processing device includes a box body 5, a cabinet door, and a clothes drying device arranged in the clothes holding cavity 1a and used for hanging clothes. The box body 5 has at least the above-mentioned clothes holding cavity 1a, the front side of the box body 5 is open, and the cabinet door is arranged at the open part of the box body 5; the clothes drying device is hung on the upper part of the clothes holding cavity 1a.

[0074] In this embodiment, the clothes can be hung on the clothes drying device and the cabinet door can be closed to process the clothes. That is, the clothes will not tumble during the drying or cleaning process, thereby reducing damage to the clothes, and the clothes will not be wrinkled or tangled after drying.

[0075] In some embodiments, as shown in Figures 3 and 4 , the laundry chamber 1a is rotatable. As the laundry chamber 1a rotates, it also moves the laundry, improving laundry handling efficiency. The laundry chamber 1a of a clothes dryer, a washing machine, and a washer-dryer all have rotatable chambers.

[0076] For example, referring to Figures 2 and 3 , the laundry processing apparatus includes a housing 5 and a laundry drum 1. The laundry drum 1 is rotatably disposed within the housing 5 and has a laundry chamber 1a. As the laundry drum 1 rotates, it moves the laundry from below to above. Under the influence of gravity, the laundry falls from above to below. Thus, the combined effects of the laundry drum 1 and gravity cause the laundry to be dispersed, thrown, and changed in position.

[0077] In some embodiments, referring to FIG. 5 , the clothes holding drum 1 is substantially cylindrical.

[0078] For example, in some embodiments, the box body 5 is roughly a hollow hexahedral structure.

[0079] 4 , the rotation axis of the clothes drum 1 may be in the horizontal direction. In other words, the clothes processing apparatus may be a drum-type clothes processing apparatus.

[0080] The rotation axis of the clothes drum 1 can be along an inclined direction. It is understood that the inclined direction is a direction in which the angle between the rotation axis of the clothes drum 1 and the horizontal direction is greater than 0° and less than 90°, forming an acute angle.

[0081] In some exemplary embodiments, the laundry processing apparatus includes a door. A clothing access opening is formed at the front of the laundry drum 1 and communicates with the laundry chamber 1a. The door is connected to the front surface of the housing 5 and is used to open and close the access opening. A user can access clothing from the front of the laundry processing apparatus.

[0082] In one embodiment, the clothes drum 1 may be a single drum structure. That is, the clothes processing device has only one drum body, the clothes drum 1.

[0083] In another embodiment, the clothes processing device includes an outer tub, which is sleeved outside the clothes holding drum 1. In other words, the clothes processing device has two barrels, namely the clothes holding drum 1 and the outer tub.

[0084] The clothing processing device has a clothes drying function. Exemplarily, in one embodiment, the clothing processing device includes a heat exchange component and a circulation air duct. A clothes loading and unloading opening is formed at the front of the clothes holding drum 1, and the clothes loading and unloading opening is connected to the clothes holding chamber 1a. A ventilation duct is formed on the front support 4, and the ventilation duct is connected to the clothes loading and unloading opening. The two ends of the circulation air duct are respectively connected to the clothes holding chamber 1a and the ventilation duct. The heat exchange component is arranged in the circulation air duct. The air flow circulates between the clothes holding chamber 1a, the clothes loading and unloading opening, the ventilation duct and the circulation air duct. The heat exchange component is used to perform heat exchange on the air flow flowing through the circulation air duct. In other words, the heat exchange component is used to heat and / or cool the air flow flowing through the circulation air duct. The temperature and humidity of the air flow flowing through the circulation air duct are changed by the heat exchange component, and the circulating air flow is provided to the clothes holding chamber 1a through the circulation air duct and the ventilation duct. In other words, the clothing processing device adopts a heat pump circulation drying method to achieve the clothes drying function.

[0085] In one embodiment, the heat exchange component includes a condenser and / or an evaporator. Refrigerant flows through both the condenser and the evaporator. Both the condenser and the evaporator are arranged in a circulating air duct. The refrigerant can circulate between the condenser and the evaporator, and the refrigerant in the evaporator and the condenser exchanges heat with the air flow in the circulating air duct to achieve heating and condensing the air flow. The evaporator is used to cool and dehumidify the hot and humid air flow from the clothing storage chamber 1a to form a dry and cold air flow. The condenser heats the dry and cold air flow into a dry and hot air flow, which is then sent into the clothing storage chamber 1a through the circulating air duct. On the flow path of the air flow in the circulating air duct, the air flow first flows through the evaporator and then flows through the condenser. Specifically, the evaporator is used to cool and dehumidify the hot and humid air flow from the clothing chamber 1a to form a dry and cold air flow. The condenser heats the dry and cold air flow into a dry and hot air flow and then flows it back into the clothing chamber 1a. The dry and hot air flow flowing back to the clothing chamber 1a comes into contact with the wet clothes to form a hot and humid air flow again, completing a drying cycle. By repeatedly running the drying cycle, circulating air flow is continuously provided to the clothing chamber 1a to dry the clothes.

[0086] It should be understood that the dry and cold airflow is relative to the humid and hot airflow. The temperature of the dry and cold airflow is lower than that of the humid and hot airflow, and the humidity of the dry and cold airflow is lower than that of the humid and hot airflow.

[0087] In some embodiments, the clothing chamber 1a has a wall without a drainage channel. That is, there is no wash water in the clothing chamber 1a and no drainage is required, that is, no wash water needs to be injected into the clothing chamber 1a.

[0088] It should be noted that the absence of a drainage channel refers to the wall of the clothing chamber 1a, and does not specifically refer to the entire clothing processing device. It is understandable that the entire clothing processing device may be equipped with or without a drainage pipe.

[0089] For example, the clothing processing device may be a clothes dryer. In some embodiments, the clothing processing device as a whole may not be equipped with a drain pipe. Instead, the clothing processing device may include a water box for collecting condensed water generated by the heat exchange component. In this way, the user can pour out the liquid in the water box by themselves. Therefore, the present application may not drain the liquid from the heat exchange component through a drain pipe to a floor drain, but instead collect it in a water box for the user to pour out. In this way, the clothing processing device of the present application does not rely on a floor drain for drainage and can be used in environments without a floor drain.

[0090] For example, in some other embodiments, the entire laundry processing device can be equipped with a drain pipe, which can be used to drain condensed water generated by the heat exchange component, such as condensed water collected in the water box. This can prevent the user from dumping the liquid in the water box and reduce user operations.

[0091] In some embodiments, the clothing processing apparatus further includes a compressor and a throttling device. The compressor, condenser, throttling device, and evaporator are sequentially connected in series via a refrigerant pipe to form a heat pump system, wherein the refrigerant circulates within the heat pump system. The airflow within the circulating air duct exchanges heat with the refrigerant in the heat pump system to form a dry hot airflow.

[0092] The heat pump system works as follows: the compressor draws in low-pressure gaseous refrigerant and compresses it to high pressure before discharging it. The discharged high-pressure refrigerant enters the condenser, where it transfers heat to the airflow, condensing it into a high-pressure liquid. The high-pressure liquid refrigerant flows through a throttling device, reducing the pressure and transforming into a low-pressure, low-temperature gas-liquid two-phase mixture before entering the evaporator. The refrigerant in the evaporator absorbs heat from the airflow and transforms into a low-pressure gas. The low-pressure gaseous refrigerant is then drawn back into the compressor. This cycle repeats, achieving heat exchange. Specifically, the evaporator cools and dehumidifies the hot and humid airflow from the clothing storage chamber 1a, forming a dry, cold airflow. The condenser heats the dry, cold airflow into a dry, hot airflow, which then flows back into the clothing storage chamber 1a. This dry, hot airflow returns to the clothing storage chamber 1a, where it comes into contact with the damp clothes, forming a humid, hot airflow again, completing a drying cycle. By repeatedly running the drying cycle, circulating airflow is continuously supplied to the clothing storage chamber 1a, drying the clothes.

[0093] For example, both the evaporator and the condenser may be fin-tube heat exchangers or microchannel heat exchangers.

[0094] Exemplarily, the throttling device includes but is not limited to an expansion valve or a capillary tube, etc.

[0095] In one embodiment, the clothing processing apparatus includes a fan configured to drive airflow between the clothing chamber 1a and the circulating air duct. Exemplarily, the fan is located within the circulating air duct. During the clothing drying process, the fan drives the airflow through the clothing, passing through the heat exchange assembly before being blown toward the clothing to form a circulating airflow. This fan can accelerate airflow and improve drying efficiency. After the clothing is cleaned, the fan can drive the airflow, allowing the cleaning agent containing dissolved stains and any small amount of water on the clothing to enter the circulating air duct along with the airflow. Water vapor in the airflow and the cleaning agent containing dissolved stains to condense into liquid within the circulating air duct.

[0096] In some embodiments, the clothes processing apparatus includes two motors, one motor is connected to the fan to drive the fan to rotate, and the other motor is connected to the clothes drum 1 to drive the clothes drum 1 to rotate.

[0097] In other embodiments, the laundry processing device includes a single motor, and the fan and the laundry drum 2 are both connected to the single motor. In other words, the single motor can drive both the fan and the laundry drum 1, thus saving one motor and reducing material costs.

[0098] In one embodiment, the dispensing device includes a foaming device that foams the cleaning agent and dispenses it into the dispensing area 2a. The foaming device converts the cleaning agent into foam, which increases the contact area between the cleaning agent and the stains in the dispensing area 2a, thereby improving the cleaning ability. For example, the clothing treatment device uses foam to clean clothing in a non-immersion manner.

[0099] It should be understood that the cleaning formulation is in liquid form before entering the foam generating device and is converted into foam within the foam generating device.

[0100] The specific structure of the foam generating device is not limited, as long as it can generate foam from the cleaning agent and discharge the foam.

[0101] Exemplary, foam is the material formed by gas dispersion in the cleaning formulation. In other words, foam is the aggregation of bubbles separated by the liquid film of the cleaning formulation. For example, a foam generating device can inject air into the cleaning formulation so that the cleaning formulation forms foam.

[0102] In one embodiment, referring to Figures 1 to 5 , the indicator device 2 includes a light emitter 21 that emits a light beam into the garment storage chamber 1a to indicate a placement area 2a. In other words, the area illuminated by the light beam, or placement area 2a, is the projection area of ​​the light beam emitted by the light emitter 21 onto the wall of the garment storage chamber 1a.

[0103] The projection area of ​​the cleaning agent dispensed by the dispensing device 3 onto the wall of the garment chamber 1a is the dispensing area 3a. The area of ​​the dispensing area 3a can be larger, smaller, or equal to the area of ​​the dispensing area 2a. The shape of the dispensing area 3a can be the same as or different from the shape of the dispensing area 2a.

[0104] In one embodiment, referring to Figures 3 to 5 , the area of ​​delivery region 3a formed by delivery device 3 in delivery zone 2a is larger than the area of ​​delivery zone 2a. For example, the area of ​​delivery zone 3a is larger than the spot size of the light beam emitted by light emitter 21. This ensures that delivery zone 2a is within the delivery range of the cleaning agent, ensuring sufficient contact between the cleaning agent and the stain.

[0105] In one embodiment, the light emitter 21 designates a specific area of ​​the clothing storage chamber 1a as the drop zone 2a. The light emitter 21 is capable of emitting a light beam toward the specific area, with the specific area where the light spot of the light beam is located being designated as the drop zone 2a. For example, the light emitter 21 can pre-designate the drop zone 2a by emitting a light beam toward the specific area. In other words, the drop zone 2a can be pre-designated in a predetermined manner, and the user can simply place the stained portion of the clothing into the specific area illuminated by the light spot. This allows for targeted cleaning of stains through simple operations, simplifying the control process of the clothing dispensing device.

[0106] The specific area can be set before leaving the factory or set by the user after leaving the factory. The position of the specific area usually does not change randomly, and the user can place the local stain in the specific area each time. It is understandable that during the use of the clothes processing device, the user can also adjust the light emitter 21 to change the position of the specific area.

[0107] In some embodiments, the size and shape of the light spot of the light beam can be adjusted. In this way, the size and shape of the delivery area 2a can be adjusted by adjusting the size and shape of the light spot, thereby adapting to stains of different sizes and shapes.

[0108] In some embodiments, the laundry treatment device includes a controller that controls the light emitter 21 to adjust the size and shape of the light beam. In other embodiments, the user can manually adjust the size and shape of the light beam.

[0109] The type of the light beam is not limited, and the light beam can be within the visible light band. For example, the light beam can be red visible light, blue visible light, or visible light of other colors, etc. In this way, it is convenient for the user to quickly distinguish the delivery area 2a.

[0110] The number of light emitters 21 can be one or more. For example, in some embodiments, there can be only one light emitter 21. This facilitates centralized treatment of clothing stains.

[0111] In one embodiment, the indicator 2 includes a stain identifier that can identify stains and indicate them as placement area 2a. This allows users to place clothing directly into the storage chamber 1a, where the stain identifier will identify the stains and indicate their location. This means users can place clothing relatively freely, with the stain identifier identifying the stains and indicating their locations.

[0112] In one embodiment, the stain identifier can identify at least one of the type and area of ​​the stain, thereby obtaining more comprehensive information about the stain and allowing for more accurate placement of the cleaning agent.

[0113] Stains can be categorized based on their chemical composition, water solubility, or the principle of stain removal. For example, stains classified by chemical composition could include pigments, fats, proteins, or hydrocarbons. For example, stains classified by water solubility could include water-soluble stains or water-insoluble stains. For example, stains classified by the principle of stain removal could include dissolution, emulsification, and decomposition.

[0114] In one embodiment, the dispensing device 3 is capable of adjusting at least one of the dispensing direction, dispensing amount, and flow rate of the cleaning agent. Adjusting the dispensing direction allows for adapting to different locations of the dispensing area 2a. Adjusting the dispensing amount allows for adapting to different areas of the dispensing area 2a. Adjusting the flow rate of the cleaning agent adjusts the force with which the cleaning agent impacts the stains in the dispensing area 2a. In this way, the cleaning agent can be adapted to the stains in the dispensing area 2a for a thorough cleaning.

[0115] For example, in one embodiment, the delivery device 3 can adjust the delivery direction based on the position of the delivery area 2a, so that the cleaning agent can be delivered to the delivery area 2a to contact the stains more accurately.

[0116] For example, in one embodiment, the dispensing device 3 can adjust the dispensing amount based on the area of ​​the dispensing area 2a, so that the dispensing amount of the cleaning agent is adapted to the area of ​​the dispensing area 2a, thereby covering the stains more comprehensively.

[0117] Exemplarily, in one embodiment, the delivery device 3 can adjust the flow rate of the cleaning agent based on the category and / or area of ​​the delivery area 2a, so that the cleaning agent can be suitable for the clothes and the cleaning agent has sufficient contact time with the stains in the delivery area 2a to better achieve the cleaning effect.

[0118] In one embodiment, referring to Figures 2 to 5 , a laundry processing apparatus includes a laundry drum assembly and a front support 4. The laundry drum assembly includes a laundry drum 1 having a laundry cavity 1a formed therein. The front support 4 is located in front of the laundry drum assembly and supports the laundry drum assembly. The indicator device 2 is disposed on the front support 4. The front support 4 supports the laundry drum assembly. The indicator device 2 is disposed on the front support 4, serving as a carrier for the indicator device 2. This eliminates the need for a separate mounting structure for the indicator device 2, facilitating easier assembly of the indicator device 2 and improving the compactness of the laundry processing apparatus.

[0119] In some embodiments, the clothes drum assembly includes an outer tub, and the front support 4 is located at the front side of the outer tub and connected to the outer tub.

[0120] In one embodiment, referring to Figures 2 to 5 , the indicator device 2 is disposed on the upper portion of the front support 4. Clothes accumulate in the lower portion of the storage chamber 1a under the action of gravity, and stains on the clothes are also located in the lower region of the storage chamber 1a. Consequently, the delivery area 2a is also located in the lower region of the storage chamber 1a. The indicator device 2 is disposed on the upper portion of the front support 4 so that the indicator device 2 can indicate the delivery area 2a. For example, the light emitter 21 emits a light beam that can illuminate the delivery area 2a in the lower region of the storage chamber 1a from above.

[0121] It should be noted that, taking the example of the rotation axis of the clothes drum 1 being parallel to the horizontal plane and extending in the front-to-back direction, in a plane perpendicular to the rotation axis of the clothes drum 1, the clothes drum 1 has a first perpendicular median line P1 that is perpendicular to the rotation axis, the first perpendicular median line P1 extends in the horizontal direction, and the upper part of the front support 4 refers to the part of the front support 4 that is located above the first perpendicular median line P1.

[0122] In one embodiment, referring to Figures 2 to 5 , the delivery device 3 is disposed on the front support 4. The front support 4 provides an installation location for the delivery device 3, solving the problem that the delivery device 3 is difficult to install.

[0123] In one embodiment, referring to Figures 2 to 5 , a dispensing device 3 is disposed above the front support 4. The dispensing device 3 sprays the cleaning agent into the garment receiving chamber 1a from above. This allows the cleaning agent to fall parabolically under the action of its initial velocity and gravity, dispersing the cleaning agent and allowing it to cover the stains within the dispensing area 2a, thereby improving the cleaning effect.

[0124] In one embodiment, referring to FIG4 , the projection of the dispensing device 3 passes through the second perpendicular midline P2, with the projection of the indicator device 2 positioned to one side of the projection of the dispensing device 3 in the left-right direction. This facilitates the dispensing device 3 in dispensing the cleaning agent into the dispensing area 2a.

[0125] It should be noted that, taking the example of the rotation axis of the clothes drum 1 being parallel to the horizontal plane and extending in the front-to-back direction, in a plane perpendicular to the rotation axis of the clothes drum 1, the clothes drum 1 has a second perpendicular midline P2 perpendicular to the rotation axis, and the second perpendicular midline P2 extends in the vertical direction.

[0126] In one embodiment, referring to Figure 4 , the front support 4 is formed with an escape opening 4a that communicates with the clothing access opening. Both the indicator device 2 and the dispensing device 3 are located above the escape opening 4a. The indicator device 2 can indicate the dispensing area 2a within the clothing compartment 1a from the front through the clothing access opening, while the dispensing device 3 can dispense cleaning solution into the dispensing area 2a from the front through the clothing access opening, preventing other structural components from obstructing the operation of the indicator device 2.

[0127] It should be noted that the indicator device 2 provided in the embodiment of the present application can be used to generate stain placement prompt information, and the delivery device 3 can be used to deliver foam. In at least some embodiments, the delivery area 2a can be a foam delivery area.

[0128] It can be understood that the clothing holding chamber is used for placing and processing clothing, and is also referred to as a clothing processing chamber in some embodiments.

[0129] FIG6 is a flow chart of a control method for a clothes processing device according to an embodiment of the present application. The control method for the clothes processing device includes:

[0130] S101: generating stain placement prompt information to instruct the user to place at least part of the stained area of ​​the clothing in the foam placement area of ​​the clothing holding chamber;

[0131] S102: Control the clothing treatment device to add foam to at least a portion of the stained area of ​​the clothing.

[0132] For example, the laundry treatment device in the embodiments of the present application can be a functional device capable of treating laundry. The laundry treatment can be one or more of cleaning, drying, and even softening. The embodiments of the present application take a functional device capable of achieving the purpose of cleaning laundry through foam as an example. In the embodiments of the present application, at least a portion of the stained area can refer to an area on the laundry corresponding to a heavier stain. Heavier stains can refer to stains that are difficult to clean. The definition of difficult to clean can be based on the type of stain. For example, protein-containing stains such as blood stains are more difficult to clean than dust stains, so the portion of the laundry stained with blood stains is more heavily stained than the portion of the laundry stained with dust. For another example, coffee stains are more difficult to clean than dust stains, so the portion of the laundry stained with coffee stains is more heavily stained than the portion of the laundry stained with dust. For another example, protein-containing stains such as blood stains are more difficult to clean than coffee stains or juice stains, so the portion of the laundry stained with blood stains is more heavily stained than the portion of the laundry stained with coffee stains or juice stains. In some possible scenarios, the heavier stains in the embodiments of the present application can also be defined based on the amount of the substance that constitutes the stain, such as the area of ​​the stain per unit area of ​​the surface of the clothing. If the stain area per unit area of ​​clothing reaches a first threshold, it can be determined that it is difficult to clean, that is, it is a heavier stain. The foam in the embodiments of the present application may refer to foam that can achieve a cleaning effect on any type of stain involved in the embodiments of the present application. The foam can be produced by mixing a cleaning solution with water and breaking it up through a clothing processing device. After the foam is generated and put into the clothing chamber, the foam mixes with the clothing in the clothing chamber or adheres to the surface of the clothing. The mechanical force generated by the bursting of the foam achieves a cleaning effect on the stains on the surface of the clothing.

[0133] Stain placement prompt information is generated to instruct the user to place at least part of the stained area of ​​the clothing in the foam placement area of ​​the clothing treatment chamber.

[0134] In some scenarios, some areas of clothing may be stained with blood, while other areas may be covered with dust and debris. For dust and debris stains on the surface of clothing, a cleaning effect can be achieved by, for example, evenly covering the entire clothing with foam. However, areas with heavier stains, such as blood, are more difficult to clean than dust and other stains. Therefore, evenly soaking all areas of the clothing with foam may result in at least some of the stained areas not being fully cleaned. To achieve a good cleaning effect on at least some of the stained areas, a large amount of foam must be used, or the user must manually clean at least some of the stained areas separately, which provides a poor user experience.

[0135] Based on the above-mentioned problems, an embodiment of the present application provides a control method for a clothing treatment device, which can generate stain placement prompt information to instruct the user to place at least part of the stained area of ​​the clothing in the foam delivery area of ​​the clothing holding chamber, and then control the clothing treatment device to deliver foam to at least part of the stained area of ​​the clothing. Exemplarily, the stain placement prompt information can refer to information used to prompt the user to place at least part of the stained area of ​​the clothing in the foam delivery area. The prompt information can be implemented in various ways, such as through sound prompts, animation prompts, light prompts, light source prompts, etc. The foam delivery area can refer to the area where the foam lands when the clothing treatment device delivers foam into the clothing holding chamber.

[0136] After the user places at least part of the stained area into the foam delivery area, when the clothing treatment device delivers foam into the clothing holding chamber, the foam can be concentratedly sprayed onto at least part of the stained area of ​​the clothing, thereby increasing the amount of foam acting on the local stain and the action time, so that the foam can fully penetrate into at least part of the stained area to dissolve the stain, thereby improving the cleaning effect of the clothing treatment device on at least part of the stained area and enhancing the decontamination effect. Therefore, compared with the prior art method of randomly placing the clothing in the clothing holding chamber and evenly soaking the clothing with foam for cleaning, the method provided in the embodiment of the present application can increase the amount of foam acting on at least part of the stained area of ​​the clothing and the action time, thereby achieving a better cleaning effect on at least part of the stained area of ​​the clothing.

[0137] In the prior art, if one wants to achieve the effect of cleaning at least a portion of the stained area as well as other parts of the clothing, a large amount of foam needs to be introduced so that all positions of the clothing are soaked with foam. Since the amount of foam soaked in the non-at least partially stained area of ​​the clothing is the same as the amount of foam soaked in the at least partially stained area, in order to achieve the effect of cleaning the stains in the at least partially stained area, the amount of foam soaked in the non-at least partially stained area of ​​the clothing is greater than the amount of foam required for cleaning. This results in the prior art requiring a larger amount of foam to be introduced as a whole. In the embodiment of the present application, after the user places the at least partially stained area into the foam delivery area, the clothing treatment device delivers foam into the clothing holding chamber. Since the foam delivered into the clothing holding chamber is fluid, the foam will flow from the initial delivery position to the surrounding areas, thereby soaking the clothing at various positions in the clothing treatment barrel, allowing the foam to fully penetrate into the clothing and dissolve the stains. Therefore, the foam can not only clean the stains at the delivery position, but also flow to other positions of other clothing to soak and decompose the stains, thereby achieving overall cleaning of the clothing. Because the foam is initially applied to at least a portion of the stained area of ​​the clothing, the amount of foam applied to at least a portion of the stained area and the duration of the foam application are greater than those applied to other areas of the clothing, resulting in a stronger decontamination effect on at least a portion of the stained area. Therefore, the embodiments of the present application can achieve a better cleaning effect on at least a portion of the stained area while using less foam, thus avoiding wasted foam. Furthermore, under the premise of using the control method for the clothing treatment device provided by the present application, the user only needs to follow the prompts to place at least a portion of the stained area into the foam application area. Compared to pre-treating at least a portion of the stained area through manual cleaning, this greatly reduces the user's operational process and improves the user experience.

[0138] In some embodiments, generating stain placement prompt information to instruct the user to place at least a portion of the stained area of ​​the clothing in the foam delivery area of ​​the clothing holding chamber includes:

[0139] The prompt light is controlled to illuminate the foam delivery area of ​​the clothing holding chamber to instruct the user to place at least a portion of the stained area of ​​the clothing in the foam delivery area of ​​the clothing holding chamber.

[0140] Exemplarily, when the clothing processing device puts foam into the clothing holding cavity, the landing point of the foam can be fixed relative to the external world coordinate system, that is, the position of the foam delivery area can be fixed, and the prompt light can be controlled to illuminate the foam delivery area. After the prompt light illuminates the foam delivery area, the brightness of the foam delivery area forms a large brightness difference with other areas, so as to achieve the purpose of clearly prompting the foam delivery area, and then prompt the user to place at least part of the stained area of ​​the clothes in the foam delivery area of ​​the clothing holding cavity, so that the foam can effectively contact at least part of the stained area.

[0141] In some embodiments, generating stain placement prompt information to instruct the user to place at least a portion of the stained area of ​​the clothing in the foam delivery area of ​​the clothing holding chamber includes:

[0142] A stain placement voice prompt message is generated to instruct the user to place at least part of the stained area of ​​the clothing in the foam placement area of ​​the clothing holding chamber.

[0143] For example, in some other possible implementations, a voice prompt can be used to remind the user to place at least a portion of the stained area of ​​the clothing in the foam delivery area of ​​the clothing receiving chamber. For example, after the user starts the clothing treatment device, the clothing treatment device can issue a reminder to the user through a speaker, "Please place at least a portion of the stained area of ​​the clothing at the bottom of the clothing receiving chamber and expose it to the air." Based on the above solution, a voice prompt can be used to remind the user to place at least a portion of the stained area in the foam delivery area, so that the foam can be directly delivered to the location corresponding to the at least portion of the stained area and contact the stain, achieving a better cleaning effect.

[0144] In some embodiments, controlling the laundry treatment device to deliver foam to at least a portion of the stained area of ​​the laundry comprises:

[0145] The clothes treating device is controlled to deliver a first amount of foam to at least a portion of the stained area of ​​the clothes, and the foam is left to stand for a preset time.

[0146] Exemplarily, the first dosage may refer to the amount of foam directed to at least a portion of the stained area. More specifically, the foam may be quantified in terms of volume or weight, and the first dosage may refer to the volume or weight of the foam directed to at least a portion of the stained area. After the first dosage of foam is directed to at least a portion of the stained area of ​​the clothing, the clothing chamber may be kept stationary for a preset time, i.e., the clothing is kept stationary for a preset time. The preset time may refer to a period of time, such as 3 minutes (time unit: minutes). During this time period, the foam may fully contact, diffuse, and react with at least a portion of the stained area, thereby achieving a better cleaning effect for at least a portion of the stained area. If, after the first dosage of foam is directed to at least a portion of the stained area, the clothing chamber is directly controlled to rotate to clean the clothing, the foam will quickly diffuse to the entire clothing based on the rotation of the clothing chamber. For at least a portion of the stained area, the amount of foam in contact with at least a portion of the stained area will be reduced. That is, from one perspective, the embodiment of the present application controls the clothing treatment device to deliver a first amount of foam to at least a portion of the stained area of ​​the clothing and allows the foam to remain stationary for a preset time so that the foam can fully diffuse, contact, and react with the at least portion of the stained area to achieve sufficient cleaning of the at least portion of the stained area, rather than diffuse, contact, and react with the entire clothing to achieve cleaning of the entire clothing. Therefore, compared to the solution of directly controlling the rotation of the clothing chamber to clean the clothing after delivering the foam, the solution of delivering the first amount of foam to at least a portion of the stained area of ​​the clothing and allowing the foam to remain stationary for a preset time in the embodiment of the present application can avoid the foam from spreading over a larger area, thereby failing to achieve a better cleaning effect on at least the portion of the stained area.

[0147] In addition, when there are clothes made of easily worn materials in the clothing cavity, adding foam into the clothing cavity in a static manner can avoid friction between clothes and between clothes and the clothing cavity, which may damage clothes and improve the user experience.

[0148] In some embodiments, after standing still for a preset time, the method further includes:

[0149] The clothes treating device is controlled to dispense a second amount of foam.

[0150] For example, in the embodiment of the present application, after the foam has been allowed to stand for a preset time to focus on cleaning at least a portion of the stained area, the second amount of foam can be controlled to be released by the clothing treatment device. The meaning of the second amount of foam is similar to that of the first amount of foam in the above embodiment, and will not be repeated here. The embodiment of the present application also does not limit the size relationship between the second amount of foam and the first amount of foam. The purpose of controlling the clothing treatment device to release the second amount of foam can be to clean the entire clothing, for example, to clean the dust attached to the clothing in the above embodiment and at least a portion of the stained area, thereby achieving a better cleaning effect for the entire clothing.

[0151] In some embodiments, controlling the laundry treating apparatus to dispense a second amount of foam comprises:

[0152] The clothes receiving chamber of the clothes treating device is controlled to rotate, and a second amount of foam is dispensed.

[0153] For example, in the process of controlling the clothing treatment device to release the second amount of foam, the second amount of foam can be released while controlling the rotation of the clothing chamber of the clothing treatment device. That is, the release direction of the second amount of foam is relatively fixed, while the position of the clothes is constantly changing. This avoids the accumulation of foam in one place due to the unchanged landing position of the foam and the unchanged position of the clothes, so that the foam can be more efficiently and relatively evenly attached to the surface of the clothes. For example, after the clothing treatment device releases 100ml (volume unit: milliliter) of foam to at least part of the stained area, it can be left to stand for 3 minutes, and then 300ml of foam can be released into the clothing chamber to clean the entire clothes. By controlling the rotation of the clothing chamber when releasing the second amount of foam into the clothing chamber, the foam can be evenly released onto the clothes at various positions in the clothing chamber, avoiding the problem of foam being released onto some areas of the clothes while not fully soaking other areas, resulting in poor cleaning effect on the clothes. The clothes are cleaned by rubbing and rolling the clothing treatment device, combined with rubbing between the clothes. The bursting of the foam during the cleaning process increases the cleaning power, thereby improving the cleaning effect of the clothing treatment device.

[0154] In some embodiments, controlling the laundry treating apparatus to dispense a second amount of foam comprises:

[0155] After controlling the clothes treating device to deliver the second amount of foam, the clothes holding cavity of the clothes treating device is controlled to rotate.

[0156] For example, while controlling the laundry treatment device to dispense the second amount of foam, the laundry chamber of the laundry treatment device can also be controlled to rotate after the second amount of foam is dispensed. This means that the foam can be assumed to have made a certain degree of contact with the surface of the clothing, and the rotation of the laundry chamber can directly clean the stains through the mechanical force generated by the foam's rupture. This avoids the foam being affected by the rotation of the laundry chamber before it has made sufficient contact with the clothing, causing it to rupture and, in turn, result in a poor cleaning effect.

[0157] In some embodiments, controlling the laundry treatment device to deliver a first amount of foam to at least a portion of the stained area of ​​the laundry comprises: controlling the laundry treatment device to deliver foam having a first concentration and a first amount of foam to at least a portion of the stained area of ​​the laundry;

[0158] Controlling the clothes treating device to dispense the second amount of foam includes: controlling the clothes treating device to dispense the foam with a solution concentration of the second concentration and a dispense amount of the second amount;

[0159] The first concentration is greater than the second concentration.

[0160] For example, the solution concentration in the embodiment of the present application may refer to the ratio of the amount of active substances in the foam that can achieve a cleaning effect. The foam in the embodiment of the present application may be produced by mixing a cleaning stock solution with a cleaning effect with water. The solution concentration may represent the content of the cleaning stock solution in the foam. The higher the solution concentration, the stronger the cleaning effect of the foam. In some scenarios, at least part of the stained area is more difficult to clean than other areas of the clothing. Therefore, a first concentration with a higher concentration and a first amount of foam can be added to focus on cleaning at least part of the stained area of ​​the clothing, while for other areas of the clothing, a second concentration with a lower concentration and a second amount of foam can be used for cleaning. Under the premise of ensuring that the cleaning effect on the clothing can be achieved, the amount of foam and / or cleaning stock solution used can be reduced.

[0161] For example, in some possible scenarios, the surface of the clothing may be stained only in at least a portion of the stained area, while other areas of the clothing are relatively clean, and the user only wants to clean at least the portion of the stained area. Therefore, the clothing can be cleaned using foam applied to at least the portion of the stained area.

[0162] In some embodiments, controlling the laundry treatment device to deliver foam to at least a portion of the stained area of ​​the laundry comprises:

[0163] The amount of foam delivered corresponding to at least a portion of the stained area of ​​the clothing is determined, and the clothing treatment device is controlled to deliver the foam of the amount of foam delivered to at least a portion of the stained area of ​​the clothing.

[0164] In an embodiment of the present application, the amount of foam dispensed corresponding to at least a portion of the stained area of ​​the clothing can be automatically determined by the clothing treatment device. For example, the clothing treatment device can analyze the at least portion of the stained area by performing image acquisition or other methods to determine the stain type, stain area, etc. of the at least portion of the stained area, and determine the amount of foam dispensed based on the stain type, stain area, and a preset mapping relationship. In some other possible embodiments, the amount of foam dispensed corresponding to at least a portion of the stained area can also be determined by manual user input. For example, the user can directly select the amount of foam dispensed using buttons, knobs, etc. provided on the device, or the user can select information such as the stain type, stain area, etc. provided on the device through buttons, knobs, etc. provided on the device, and the clothing treatment device can determine the amount of foam dispensed based on the user-input information such as the stain type, stain area, etc. and a preset mapping relationship. That is, based on the above scheme, the embodiment of the present application can determine the amount of foam dispensed corresponding to at least a portion of the stained area of ​​the clothing, and control the clothing treatment device to dispense the foam dispensed to at least a portion of the stained area of ​​the clothing, thereby avoiding foam waste while ensuring that the at least portion of the stained area can be cleaned effectively.

[0165] In some embodiments, generating stain placement prompt information includes:

[0166] Confirm that the clothes treatment device is started and generate a stain placement reminder message.

[0167] For example, embodiments of the present application can generate stain placement prompt information directly after determining that the laundry treatment device is activated. For example, after the user activates the laundry treatment device, a prompt light can be directly illuminated at the location corresponding to the foam placement area in the laundry chamber to prompt the user to place at least part of the stained area in the foam placement area. This can reduce the user's operational process and provide great convenience to the user.

[0168] In some embodiments, generating stain placement prompt information includes:

[0169] Confirm to start the foam cleaning program and generate a stain placement prompt.

[0170] For example, the foam cleaning program in the embodiments of the present application may refer to an application program for cleaning clothes that is controlled by a controller of a laundry treatment device. In one possible embodiment, a stain placement prompt message may be generated after the user activates the foam cleaning program. In another possible embodiment, the foam cleaning program may include multiple types, such as a normal cleaning program and a stain indication cleaning program. For example, a normal cleaning program may involve the user randomly placing clothes into a laundry chamber, then injecting foam into the chamber to evenly soak the clothes and clean the entire garment. A stain indication cleaning program is a program in which, after the user activates the stain indication cleaning program, a stain placement prompt message is generated, instructing the user to place at least a portion of the stained area of ​​the clothes in the foam delivery area of ​​the laundry chamber, and then controlling the laundry treatment device to deliver foam to at least that portion of the stained area of ​​the clothes. If the user selects the normal cleaning program, the laundry treatment device does not generate the stain placement prompt message to avoid causing confusion to the user. After the user selects the stain indication cleaning program, the laundry treatment device generates a stain placement prompt message to instruct the user to place at least a portion of the stained area of ​​the clothes in the foam delivery area of ​​the laundry chamber. Therefore, the embodiment of the present application can generate stain placement prompt information after determining to start the stain cleaning program to reduce the impact on the user, and only remind the user in scenarios where the user needs it, thereby improving the user's usage experience.

[0171] The inventors conducted the following experiments using the above-mentioned control method for a laundry processing device:

[0172] Experiment 1: Two identical synthetic suits were used as carriers for heavily stained clothing. The same amount of stain was dropped onto each garment: 30 μl of coffee (volume unit: microliters), 30 μl of soy sauce, 50 μl of red wine, and 30 μl of blood. The stains of the same type were placed in the same locations on both garments. The garments were then left at a constant temperature and humidity for 24 hours. The cleaning schedules shown in Table 1 were used for each garment:

[0173] Table 1

[0174] Among them, the detergent concentration in the above Table 1 can represent the concentration of detergent (active substance) with cleaning ability in the foam, that is, 400ml of foam contains 2g (weight unit: gram) of detergent. In Experiment 1, the solution adopted in Scheme 1 is to directly put 400ml of foam into the clothing chamber to clean the entire clothing. The solution adopted in Scheme 2 is to first put 100ml of foam into at least part of the stained area for pretreatment, let it stand for 3 minutes (time unit: minute), and then put 300ml of foam into the clothing chamber to clean the entire clothing. Based on the above experiments, it can be concluded that the clothes treated by Scheme 2 can achieve better cleaning effects on all types of stains, while the clothes treated by Scheme 1 and with the same amount of foam can achieve better cleaning effects on coffee, red wine and soy sauce, but cannot completely clean blood stains, that is, cannot achieve better cleaning effects on at least part of the stained area.

[0175] Experiment 2: Two identical blended windbreakers were used as carriers for heavily stained clothing. The same amount of stain was dropped onto each garment: 30μl of coffee, 30μl of soy sauce, 50μl of red wine, and 30μl of blood. The stains of the same type were placed in the same locations on both garments. The garments were then left at a constant temperature and humidity for 24 hours. The cleaning schedule shown in Table 2 was used for each garment:

[0176] Table 2

[0177] In Experiment 2, Scheme 1 employed a method of directly injecting 400ml of foam into the garment chamber to clean the entire garment. Scheme 2 employed a method of first injecting 100ml of foam into at least a portion of the stained area, allowing it to rest for 3 minutes before injecting 300ml of foam into the garment chamber to clean the entire garment. Based on the results of these experiments, the garments treated with Scheme 2 achieved excellent cleaning results for all types of stains. While the garments treated with Scheme 1, with the same amount of foam injected, achieved excellent cleaning results for coffee, red wine, and soy sauce, they were unable to completely clean blood stains, meaning they were unable to achieve an adequate cleaning effect on at least a portion of the stained area.
