[0044] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments will be described clearly and completely below with reference to the drawings of the embodiments of the present application. The following embodiments are used to explain the present application but are not used to limit the scope of the present application.

[0045] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0046] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] As shown in FIGS. 1-7, the first aspect of the present application provides a clothes treatment device, comprising an outer cylinder 100 and an inner cylinder 200 rotatably mounted in the outer cylinder 100, further comprising: a treatment agent dispensing device 300;

[0048] The treatment agent dispensing device 300 comprises a dispensing module 310, which is provided with a first dispensing port 311 and a second dispensing port 312. The first dispensing port 311 is in communication with the chamber between the inner and outer cylinders, for dispensing treatment agent into the chamber; the second dispensing port 312 is in communication with the inner cylinder 200, for dispensing treatment agent into the inner cylinder 200.

[0049] In this embodiment, the clothes treatment device comprises an inner cylinder 200, an outer cylinder 100 and a treatment agent dispensing device 300 for dispensing treatment agent. The outer cylinder 100 serves as the main part of the clothes treatment device, providing a stable support environment for the inner cylinder 200 and the washing process; the inner cylinder 200 is mounted inside the outer cylinder 100 and can rotate about its axis, and is a key component for realizing functions such as clothes washing and spin-drying.

[0050] The core component of the treatment agent dispensing device 300 is the dispensing module 310, which is mainly used to dispense treatment agents such as detergents, softeners and disinfectants to designated locations, including but not limited to the inside of the inner cylinder 200 and the chamber between the inner cylinder 200 and the outer cylinder 100.

[0051] Specifically, the dispensing module 310 is provided with a first dispensing opening 311 and a second dispensing opening 312, which correspond to different dispensing requirements. The first dispensing opening 311 is in communication with the chamber between the inner and outer drums, and the treatment agent (such as detergent, softener, disinfectant, etc.) dispensed through the first dispensing opening 311 will directly enter the space between the outer drum 100 and the inner drum 200, i.e. the "inter-drum space". This mode is particularly suitable for scenarios where a layer of treatment agent film needs to be formed between the clothes and the inner drum 200, or the clothes need to be pre-soaked, disinfected, etc. In addition, since the treatment agent does not directly contact the clothes, it can also effectively reduce the wear and tear and discoloration of the clothes.

[0052] The second dispensing opening 312 is different from the first dispensing opening 311, and the second dispensing opening 312 directly communicates to the inside of the inner drum 200. The treatment agent dispensed through the second dispensing opening 312 can directly act on the clothes, which is suitable for scenarios where direct contact with the clothes is needed to achieve deep cleaning, stain removal or special care. For example, during the washing process, the type and amount of treatment agent can be accurately controlled according to the material of the clothes, the type of stains, etc., to achieve the best washing effect.

[0053] Further, the dispensing priority of the second dispensing opening 312 is higher than that of the first dispensing opening 311.

[0054] In this embodiment, the second dispensing opening 312 directly communicates to the inside of the inner drum 200, so that the dispensed treatment agent can immediately and directly act on the clothes, ensuring that the treatment agent can more effectively penetrate into the fibers of the clothes to remove stains or achieve specific treatment effects. By preferentially dispensing the treatment agent through the second dispensing opening 312, the treatment effect, such as the reduction of stains or the change of color, can be seen more quickly, so that the treatment strategy can be adjusted in time or additional treatment agent can be added.

[0055] Further, the dispensing module 310 includes a dispensing pipe 313, and the first dispensing opening 311 and the second dispensing opening 312 are arranged on the dispensing pipe 313, and the second dispensing opening 312 is arranged at the end of the dispensing pipe 313;

[0056] Preferably, the dispensing pipe 313 is mounted on the front end cover of the outer drum 100, the first dispensing opening 311 faces the chamber, and the second dispensing opening 312 is arranged at the front end opening of the inner drum 200 and faces the inside of the inner drum 200.

[0057] In this embodiment, the dispensing pipe 313 is the core component of the dispensing module 310, responsible for transporting the treatment agent from the storage container to the designated dispensing opening. The first dispensing opening 311 and the second dispensing opening 312 are arranged on the dispensing pipe 313, and these two dispensing openings are respectively used to dispense treatment agent to the chamber between the inner and outer drums and the inside of the inner drum 200.

[0058] Specifically, the second liquid injection port 312 is arranged at the end of the liquid injection pipe 313, and when the treatment agent flows through the liquid injection pipe 313, it will first reach and pass through the second liquid injection port 312 into the inner cylinder 200. The liquid injection pipe 313 is installed on the front end cover of the outer cylinder 100, and necessary operations can be performed on the liquid injection pipe 313 without moving the entire device. The first liquid injection port 311 is located on the liquid injection pipe 313, and its orientation is arranged to directly aim at the chamber between the inner and outer cylinders; when the treatment agent is injected through the first liquid injection port 311, it will directly enter the chamber between the inner and outer cylinders and indirectly contact the clothes, achieving the effects of pre-soaking, disinfection, etc. As mentioned earlier, the second liquid injection port 312 is located at the end of the liquid injection pipe 313 and is arranged at the front end opening of the inner cylinder 200; the orientation of the second liquid injection port 312 ensures that the treatment agent can be directly sprayed into the inner cylinder 200, directly contacting the clothes to achieve the effects of deep cleaning, stain removal, etc.

[0059] Further, the first liquid injection port 311 is located higher than the second liquid injection port 312, and the injection module 310 is configured to inject treatment agent from the first liquid injection port 311 when the second liquid injection port 312 is blocked.

[0060] In this embodiment, the position of the first liquid injection port 311 is designed to be higher than the second liquid injection port 312, which not only facilitates the flow management of the liquid inside the injection module 310, but also provides a solution for the case of blockage. Under normal circumstances, the treatment agent preferentially enters the inner cylinder 200 through the second liquid injection port 312 to achieve direct and efficient cleaning effects. However, when the second liquid injection port 312 cannot work normally due to some reasons (such as blockage, scaling, etc.), the first liquid injection port 311 with a higher height becomes an alternative injection path.

[0061] Specifically, the response mechanism of the injection module 310 can include various mechanisms, such as: the injection module 310 is integrated with an intelligent sensing or monitoring system, which can detect the injection state of the second liquid injection port 312 in real time. Once a blockage or other abnormal condition is found, the system should automatically switch to the first liquid injection port 311 for injection to ensure the continuity of the treatment process. For example, manually switch the first liquid injection port 311 and the second liquid injection port 312, when the device fails or needs special treatment, the injection port can be manually adjusted according to the actual situation to meet the specific treatment needs. For example, no switching mechanism is provided, and after the second liquid injection port 312 is blocked, the treatment agent will accumulate in the liquid injection pipe 313, and over time, the liquid injection pipe 313 will accumulate full of treatment agent, which will then flow out from the first liquid injection port 311.

[0062] More specifically, during the execution of the washing program, the treatment agent dispensing device 300 dispenses the treatment agent, which, under the action of gravity, is dispensed into the inner drum 200 through the liquid dispensing pipe 313 and the second liquid dispensing opening 312; if the second liquid dispensing opening 312 is blocked, the liquid volume in the liquid dispensing pipe 313 will be stored, at which time the treatment agent is dispensed into the chamber between the inner drum 200 and the outer drum 100 through the first liquid dispensing pipe 313 to ensure normal dispensing of the treatment agent. At this time, the treatment agent will not be directly dispensed onto the clothes, but will be dispensed into the chamber between the inner drum 200 and the outer drum 100 through the first liquid dispensing opening 311. The treatment agent dispensed into the chamber between the inner drum 200 and the outer drum 100 will indirectly contact and act on the clothes with the circulation and flow of the washing water.

[0063] In the subsequent water inlet process, the incoming water flow will continuously scour the liquid dispensing pipe 313 and the second liquid dispensing opening 312, and the treatment agent causing the blockage of the second liquid dispensing opening 312 will be dissolved with the scouring of the water flow, thereby enabling the second liquid dispensing opening 312 to be unblocked to ensure that the next time the treatment agent is dispensed, it can smoothly enter the inner drum 200 through the second liquid dispensing opening 312.

[0064] Further, the second liquid dispensing opening 312 is provided with a clothes recognition assembly 3122 for recognizing the clothes in the inner drum 200.

[0065] Preferably, the second liquid dispensing opening 312 is provided with a spray head 3121 through which the treatment agent is dispensed into the inner drum 200.

[0066] Preferably, the spray head 3121 is a high-pressure spray head through which the treatment agent is pressurized and then dispensed into the inner drum 200.

[0067] In this embodiment, the clothes recognition assembly 3122 is a highly integrated intelligent system that uses advanced sensor technology and image recognition algorithms to accurately recognize the position and material of the clothes in the inner drum 200. These sensors can include infrared sensors, cameras, weight sensors, etc., which can capture images, weight distribution, and possible material characteristics of the clothes.

[0068] By analyzing the reflection spectrum, color change, texture characteristics, etc. of the clothes under a specific light source, the clothes recognition assembly 3122 can accurately determine the type of material of the clothes. This is crucial for subsequent selection of appropriate washing programs and treatment agents, as different materials of clothes have different absorption, reactivity, and tolerance to treatment agents. It should be noted that the second liquid dispensing opening is not higher than the height of the treatment agent dispensing device 300, and further, not higher than the liquid level of the mixed liquid in the treatment agent mixing device.

[0069] In this embodiment, a spray head 3121 is provided at the second dispensing port 312 and combined with a laundry identification assembly 3122. The spray head 3121 is a key component that can dispense the treatment agent into the inner drum 200 in a spraying manner. This spraying technique can ensure that the treatment agent uniformly and quickly covers the surface of the laundry, improving the washing efficiency and quality.

[0070] As a preferred solution, the spray head 3121 is a high-pressure spray head, and high-pressure spraying helps to penetrate deep into the fibers of the laundry and remove stubborn stains. The high-pressure spray head is internally provided with a pressure pump or similar device that can pressurize the stored treatment agent to a certain pressure range and spray it out at high speed through the small opening of the spray head 3121. This pressure can be adjusted as needed to adapt to different materials and types of stains on the laundry.

[0071] Further, the laundry identification assembly 3122 includes a laundry marking unit for marking the position of the laundry in the inner drum 200.

[0072] The angle of the spray head 3121 is adjusted according to the position of the laundry marked by the laundry marking unit.

[0073] Further, the laundry identification assembly 3122 also includes a laundry material identification unit for identifying the material of the laundry in the inner drum 200.

[0074] The flow rate of the spray head 3121 is adjusted according to the material of the laundry identified by the laundry material identification unit.

[0075] In this embodiment, the laundry identification assembly 3122 includes a laundry marking unit and a laundry material identification unit, which respectively mark and identify the position and material of the laundry in the inner drum 200.

[0076] Specifically, the laundry marking unit uses advanced image recognition or sensor technology to track and mark the position of each piece of laundry in the inner drum 200 in real time. These marking information will serve as an important basis for adjusting the angle of the spray head 3121. By accurately grasping the position of the laundry, the device can ensure that the treatment agent is directly sprayed to the area that needs to be treated, avoiding waste and mis-spraying. According to the position information provided by the laundry marking unit, the control system will adjust the spray angle of the spray head 3121 in real time, so that the spray can accurately cover every corner of the laundry, regardless of how the laundry is stacked or distributed, to ensure the effective use of the treatment agent.

[0077] The clothing material identification unit is another important component of the clothing identification assembly 3122, which uses spectral analysis, mechanical touch, or other advanced technologies to accurately identify the material of the clothing. Different materials of clothing have different absorption capacity, tolerance, and reaction speed to the treatment agent, so it is necessary to select the appropriate treatment agent and spray flow rate according to the material. Once the clothing material identification unit determines the material of the clothing, the control system will adjust the spray flow rate of the spray head 3121 according to the preset parameters or algorithms. For materials with strong absorption capacity, such as cotton and polyester, the spray flow rate can be appropriately increased to improve cleaning efficiency; while for sensitive or easily damaged materials, such as silk and wool, the flow rate needs to be reduced to avoid excessive treatment.

[0078] Further, the treatment agent dispensing device 300 is provided with a mixing chamber 320 and a monitoring unit 322, the mixing chamber 320 is in communication with the dispensing module 310;

[0079] The monitoring unit 322 is used to monitor the particle size of the treatment agent in the mixed solution in the mixing chamber 320.

[0080] In this embodiment, the treatment agent dispensing device 300 contains a mixing module, the inside of the mixing module forms a mixing chamber 320, the treatment agent and water are fully mixed in the mixing chamber 320 to form a uniform mixed solution, which can more effectively contact with the clothing in the subsequent washing process, improving the washing efficiency. The mixing chamber 320 is connected to the dispensing module 310 through a pipeline. When the uniform mixed solution is formed in the mixing chamber 320, the control system triggers the dispensing module 310 to dispense the mixed solution into the inner drum 200 or the chamber between the inner drum 200 and the outer drum 100 through the first dispensing port 311. The dispensing module 310 intelligently selects the dispensing position and the dispensing amount according to the requirements of the washing program and the identification results of the clothing identification assembly 3122.

[0081] Specifically, the mixing chamber 320 is provided with two input ports connected to the water inlet pipeline and the treatment agent inlet pipeline respectively, water and treatment agent enter the mixing chamber 320 through the corresponding pipelines, mix in the mixing chamber 320 to form a uniform mixed solution, and then enter the dispensing module 310 through the dispensing pipeline. The mixed solution in the dispensing module 310 is dispensed into the inner drum 200 through the second dispensing port 312, if the second dispensing port 312 is blocked or fails, it is dispensed into the chamber between the inner drum 200 and the outer drum 100 through the first dispensing port 311.

[0082] In this embodiment, a stirring unit 321 and a monitoring unit 322 are provided in the mixing chamber 320. The stirring unit 321 is a core component in the mixing chamber 320, and its main function is to facilitate the thorough mixing of water and treatment agent, ensuring the formation of a uniform mixture in a short time, which is crucial for improving the washing effect, as a uniform mixture can penetrate more effectively into the fibers of the clothes, removing stains and odors. The stirring unit 321 can employ various mixing techniques, such as stirring, spraying, vortex, etc. The stirrer generates strong vortex and shear force by rotating, dispersing water and treatment agent into small particles and mixing uniformly; the spraying device uses high-pressure water flow to spray the treatment agent into the water, forming fine droplets, increasing the contact area, and accelerating the mixing process.

[0083] The monitoring unit 322 is used to monitor the particle size of the treatment agent in the mixture in the mixing chamber 320 in real time. Particle size is one of the important indicators of the uniformity of the mixture, which reflects the dispersion degree and stability of the treatment agent in the mixture. By monitoring the particle size, problems in the mixing process can be found in time, such as treatment agent clumping, uneven dispersion, etc., so that appropriate measures can be taken to adjust.

[0084] The monitoring unit 322 can use optical, acoustic or electrical sensor technology to monitor the particle size of the mixture. For example, an optical sensor can infer the size and distribution of the particle size by measuring the scattering or absorption characteristics of the mixture to light; an acoustic sensor can use the propagation characteristics of ultrasonic waves in the mixture to detect the presence and concentration of particles. The monitoring unit 322 transmits the collected data to the control system in real time, and the control system judges the quality of the mixture according to the preset threshold or algorithm and issues appropriate adjustment instructions.

[0085] Specifically, the monitoring unit 322 monitors the particle size of the treatment agent in the mixture, and if the particle size is low, the mixture is directly discharged into the inner drum 200; if the particle size of the treatment agent is large, the stirring unit 321 is operated again to continue mixing water and treatment agent until the particle size of the treatment agent in the mixture meets the discharge requirements. The discharge requirements here refer to the particle size of the treatment agent in the mixture that can be maximally absorbed by the clothes.

[0086] Further, the laundry treatment apparatus also comprises a circulating device 400, which transports the treatment agent discharged between the inner drum 200 and the outer drum 100 into the inner drum 200.

[0087] In this embodiment, the laundry treatment device is also equipped with a circulation device 400, which is a key system in the laundry treatment device responsible for circulating the treatment agent or mixed solution between the inner drum 200 and the outer drum 100 into the inner drum 200. Through the circulation flow, the washing liquid can more fully contact with the laundry, remove stains and odors, and at the same time, take away the impurities and residues on the surface of the laundry.

[0088] The circulation device 400 generally includes components such as pumps, pipes, valves, etc. The pump serves as a power source to suck the washing liquid in the outer drum 100 and deliver it to the inner drum 200 through the pipe by generating a pressure difference. During the delivery process, the valve can control the flow direction and flow rate of the washing liquid to ensure the smooth progress of the circulation process. At the same time, in order to avoid damage or blockage of the pipe caused by impurities in the washing liquid, the circulation device 400 can also be equipped with a filter and other auxiliary equipment.

[0089] In a second aspect of the present application, a control method of a laundry treatment device is provided, comprising the following steps: mixing water and a treatment agent in a mixing chamber to form a mixed solution;

[0090] Obtaining the particle size of the treatment agent in the mixed solution;

[0091] According to the particle size of the treatment agent, the mixed solution in the mixing chamber is selectively stirred or the mixed solution is poured.

[0092] Optionally, it also includes: obtaining the position of the laundry in the inner drum; adjusting the angle of pouring the mixed solution according to the position of the laundry in the inner drum; and / or, obtaining the material of the laundry in the inner drum; adjusting the flow rate of pouring the mixed solution according to the material of the laundry in the inner drum.

[0093] In this embodiment, a control method of a laundry treatment device is provided, which ensures efficient use of the treatment agent and washing effect by precisely controlling the mixing, monitoring and adjusting processes.

[0094] First, water and a treatment agent are input into the mixing chamber of the mixing module. This process can be completed through a preset program or user operation to ensure that the appropriate amount of water and treatment agent enters the mixing chamber. In the mixing chamber, the stirring unit starts to work to promote the thorough mixing of water and treatment agent to form a uniform mixed solution. The stirring unit can use stirring, spraying or vortex technology to accelerate the mixing process and ensure the uniformity of the mixed solution. At the same time, the monitoring unit is used to monitor the particle size of the treatment agent in the mixed solution in the mixing chamber in real time. This step is crucial to ensure the quality of the mixed solution, as the particle size directly reflects the dispersion degree and stability of the treatment agent in the mixed solution.

[0095] The clothes processing device control method of the present application realizes the refinement and efficiency of the clothes processing process through accurate control of the preparation and delivery of the mixed solution and intelligent adjustment combining the position and material of the clothes.

[0096] Then, the monitoring unit transmits the collected data to the control system in real time, and the control system determines whether the quality of the mixed solution meets the requirements according to the preset threshold or algorithm. According to the monitoring result, the control system will issue corresponding adjustment instructions. If it is monitored that the granularity is too large or the mixing is uneven, the control system will control the stirring unit to continue working to enhance the mixing effect. When the mixed solution reaches the preset quality standard, the control system will trigger the delivery module to deliver the mixed solution into the inner cylinder.

[0097] The clothes recognition component recognizes the position and / or material of the clothes in the inner cylinder, providing important reference information for the subsequent washing process. According to the recognition result of the clothes recognition unit, the control system can adjust the angle and flow rate of the mixed solution delivered by the spray head. For clothes of different materials, such as delicate silk or rough cotton, the control system will adjust the parameters of high pressure accordingly to ensure that the treatment agent can uniformly and gently cover the surface of the clothes, avoiding damage to the clothes.
