Abstract

The present application provides a control method of a laundry treating apparatus, which directly sprays an additive to laundry along with a water flow, washes the laundry wetted by the sprayed additive, performs defoaming treatment on the washed laundry, and performs a subsequent laundry treatment process on the defoamed laundry. The subsequent laundry treatment, such as rinsing, is performed after the defoaming treatment on the washed laundry, thereby preventing problems, such as the subsequent laundry treatment process being affected by excessive foam generated from the laundry having a high content of the additive after the washing treatment. In particular, the present application achieves a significant technical progress in that the laundry having a high content of the additive after the execution of a concentrated washing program can effectively prevent excessive foam from being generated in a drum when the subsequent program is executed. Meanwhile, the present application also discloses a laundry treating apparatus using the above control method.

Description

Technical Field

[0001] This invention belongs to the technical field of clothing treatment equipment, specifically relating to a control method for clothing treatment equipment, and more particularly to a control method for reducing the amount of defoaming generated during operation in a clothing treatment equipment that directly sprays additives onto clothing with inlet water. Background Technology

[0002] Existing washing machines are generally equipped with a water tank for holding washing water, and a rotating washing drum is installed inside the water tank. The washing drum has a dehydration hole that connects the inside and outside, so that the washing water flowing into the water tank can flow back and forth between the inside and outside of the washing drum through the dehydration hole, so as to achieve the effect of contacting the washing water with the load to be processed in the washing drum and using the washing water to process the load.

[0003] The existing method of adding additives to washing machines is as follows: The additive is added through an additive dispensing device into a pipe connected to the washing machine's water drum, and then flows into the water drum along the pipe. Therefore, the additive dispensed in this method is located inside the water drum but outside the washing tub, and cannot directly contact the load inside the washing tub.

[0004] Then, during the washing cycle, the added additive mixes with the wash water flowing into the drum. A portion of this additive-mixed wash water flows into the drum through the dehydration hole, coming into contact with the load inside. Only then can a small portion of the additive mixed in the wash water come into contact with the load and exert its effect. Therefore, traditional additive dispensing methods suffer from low additive utilization efficiency and additive waste.

[0005] Meanwhile, in traditional additive dosing methods, to ensure that the additive placed between the water tank and the washing drum comes into contact with the load to be treated inside the washing drum, a large amount of water needs to be poured into the water tank until the water level in the water tank is higher than that in the washing drum. Only then can the washing water flow into the washing drum through the dewatering hole and ensure that the additive comes into contact with the load inside the washing drum. Therefore, traditional additive dosing methods also have the problem of using too much water for additive dosing.

[0006] To this end, the applicant previously proposed a technical solution that directly sprays the additive onto the clothing with the incoming water, allowing the additive to be directly applied to the clothing. By adopting the above solution, since the additive is directly sprayed onto the clothing, not only is the amount of additive wasted and the amount of incoming water reduced, but the washing and other clothing treatment effects of the clothing treatment equipment are also significantly improved.

[0007] However, in the above method, the additives are sprayed directly onto the clothes, resulting in a high concentration of additives on the clothes; at the same time, the washing water does not come into contact with the clothes during the washing process, resulting in a high concentration of additives remaining on the clothes after washing; if water is added into the washing drum after washing and used for subsequent treatments such as rinsing the clothes, a large amount of foam will be generated in the drum.

[0008] In view of this, the present invention is hereby proposed. Summary of the Invention

[0009] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a method for adding additives, so as to achieve the purpose of uniformly mixing water and detergent and then directly spraying it into the washing drum to wash the clothes. Simultaneously, this invention also provides a control method for clothing treatment equipment to reduce the amount of foam generated during operation, thereby achieving the purpose of defoaming clothing with excessive additive content.

[0010] To achieve the above-mentioned objectives, the basic concept of the technical solution adopted by this invention is as follows:

[0011] This invention provides a control method for a garment processing device, which involves spraying an additive directly onto the garment along with the incoming water flow; washing the garment soaked with the sprayed additive; defoaming the washed garment; and then subjecting the defoamed garment to subsequent garment processing procedures.

[0012] Furthermore, the washed clothes undergo a defoaming treatment, including the following:

[0013] Water is introduced into the washing drum of the garment processing equipment, and the water flow rinses the clothes inside the drum.

[0014] And / or, the washing drum rotates at a set speed, and the clothes inside the washing drum are adhered to the drum wall by centrifugal force and rotate together with the washing drum. After the additives and / or water on the clothes are separated, they flow out of the washing drum.

[0015] Furthermore, the washed clothes undergo a defoaming treatment, including the following:

[0016] Step S1: Control the washing drum to rotate at the set speed, causing the clothes inside the drum to stick to the drum wall and rotate together with the washing drum. The water contained in the clothes is separated and thrown out of the washing drum by the centrifugal force of rotation.

[0017] Step S2: Water is introduced into the washing drum. The washing drum rotates synchronously when water is introduced, causing the clothes inside the drum to stick to the drum wall and rotate with the washing drum. The water flow washes the clothes that are sticking to the drum wall and rotating with the washing drum.

[0018] Preferably, the incoming water is sprayed from inside the washing drum toward the drum wall onto the clothes that are rotating against the drum wall.

[0019] Furthermore, in step S2, the amount of rinsing water entering the washing drum is a set value L, which is a preset value corresponding to any or a combination of the type and weight of the clothes in the washing drum and the selected program.

[0020] In steps S1 and S2, the washing drum rotates unidirectionally at the set speed. The clothes inside the washing drum are subjected to centrifugal force and stick to the drum wall, rotating together with the drum. The additives and / or water on the clothes are separated from the clothes by centrifugal force.

[0021] Furthermore, during the defoaming process of the clothing processing equipment, the water level H in the water tank is detected; when the water level H in the water tank reaches or is about to reach the minimum height H1 of the washing drum, the clothing processing equipment stops feeding water into the washing drum.

[0022] Furthermore, when the defoaming process in the garment processing equipment reaches the set time point, a flipping step is performed;

[0023] The tumbling step includes the washing drum rotating at a set rotation-stop ratio, and the clothes inside the washing drum being tumbled by the centrifugal force of the washing drum which changes its rotation speed and / or direction.

[0024] After the washing drum completes the tumbling step, it continues to perform defoaming treatment. The washing drum is controlled to rotate at a set speed, causing the clothes inside the drum to stick to the drum wall and rotate with the washing drum. The incoming water flow continues to rinse the clothes that are sticking to the drum wall and rotating with the washing drum.

[0025] Furthermore, the additives and / or the incoming water flow are sprayed directly into the washing drum from the top of the drum opening, and the additives and / or the incoming water flow are sprayed from inside the washing drum towards the drum wall onto the clothes rotating against the drum wall, so as to wash or rinse the clothes.

[0026] Preferably, during the process of spraying water onto the clothes in the washing drum, the water level H in the water tank is always lower than the minimum height H1 of the washing drum.

[0027] Furthermore, after the additive is added, the washing drum rotates according to the set rotation-stop ratio and speed corresponding to the selected program to wash the clothes inside the washing drum.

[0028] Furthermore, the subsequent garment processing steps after the defoaming treatment include any or a combination of washing, rinsing, dehydration, and drying procedures.

[0029] Preferably, a rinsing process is performed on the clothes after defoaming treatment.

[0030] The present invention also provides a garment processing device employing the control method of any of the above-described garment processing devices, comprising a water supply path through which incoming water flows, and an additive dispensing structure for dispensing additives into the water supply path; the outlet of the water supply path is connected to a water outlet structure disposed in the washing drum of the garment processing device, for spraying the additives and / or incoming water directly onto the garments contained in the washing drum.

[0031] Furthermore, the washing drum is coaxially and rotatably installed inside the water tank. A water passage hole is provided on the washing drum, which connects the internal space of the washing drum with the space between the washing drum and the water tank. A water level sensor is provided on the water tank to detect the water level inside.

[0032] Furthermore, a heater is installed at the bottom of the water tank to heat the water inside; the bottom of the water tank is also connected to a drain pipe, and a control device is installed on the drain pipe to control the flow of water in the pipeline.

[0033] In a further preferred embodiment, the garment processing equipment also includes a drying system, which includes an air duct located outside the water tank. The air duct is equipped with a heating device that can generate a drying hot airflow. The air outlet of the air duct is connected to the water tank. The drying hot airflow generated in the air duct flows into the washing drum inside the water tank to heat the garments placed in the washing drum.

[0034] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0035] By defoaming the washed clothes before rinsing and other subsequent processing, problems such as excessive foam generation affecting subsequent processing procedures can be avoided, especially for clothes with high additive content after a concentrated wash cycle. This represents a significant technological advancement that prevents excessive foam generation in the drum during subsequent processes.

[0036] Meanwhile, through the above control method, the additive mixture is sprayed directly and evenly onto the clothes in the washing drum, so that the clothes to be washed are directly wetted by the mixture. This not only reduces water consumption during the washing process, but also allows the additive to be directly and evenly distributed on the clothes, improving the efficiency of additive use and reducing additive waste.

[0037] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use.

[0038] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0052] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0054] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0055] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] like Figures 1 to 6 As shown in the illustration, this invention also introduces a garment processing device, comprising: a water tank 200 for holding water, a rotatable washing drum 300 for holding the load to be processed installed inside the water tank 200, and an additive dispensing device 100 for directly dispensing additives into the washing drum 300. Through the above configuration, the washing machine can achieve the effect of directly dispensing additives into the washing drum 300 and directly spraying the dispensed additives onto the load to be processed within the washing drum 300, thereby achieving a significant technological advancement in improving the utilization rate of additives.

[0057] In this embodiment of the invention, the garment processing equipment can be any or a combination of functions such as washing, drying, ironing, and refurbishing, such as a washing machine, a washer-dryer combo, etc.

[0058] In this embodiment of the invention, the additive dispensing device can dispense any existing solid, liquid, or gaseous clothing additive into the washing drum, such as any or a combination of laundry powder, detergent, rinsing agent, fabric softener, disinfectant, bleach, etc.

[0059] like Figures 1 to 6 As shown, the additive dispensing device 100 in this embodiment of the invention includes: a water supply path 1 for supplying water into the additive dispensing device 100; a dispensing structure for dispensing additives into the water supply path 1; and a nozzle 500, with the outlet 11 of the water supply path 1 connected to the nozzle 500 via a conduit 600, and the nozzle 500 facing the washing machine drum 300. When the additive is dispensed, a small amount of water flows into the water supply path, causing the additive to mix with the small amount of water in the water supply path 1 to form an additive solution. The additive solution supplied by the water supply path 1 can be directly sprayed through the nozzle 500 onto the load to be treated inside the washing drum 300, thereby significantly improving the utilization rate of the dispensed additive.

[0060] The above-mentioned device allows the additive to be directly dispensed through the water channel provided on the dispensing device 100, avoiding the additive from flowing through the water box. This not only reduces the flow path of the additive but also reduces the amount of rinsing water required for additive dispensing, greatly improving the utilization rate of the additive.

[0061] In this embodiment of the invention, the nozzle 500 can be any existing water inlet structure capable of spraying water into the clothes in the washing drum; for example, a shower head or spray nozzle. In this embodiment of the invention, the nozzle 500 may have only one spray hole or multiple spray holes, so that the spray water flowing into the washing drum from the nozzle can flow directly onto the clothes in the washing drum in any form such as spraying or sprinkling, thereby achieving the effect of wetting the clothes and / or adding additives.

[0062] like Figures 1 to 6 As shown, in this embodiment of the invention, the water supply path 1 is integrated into the outer shell 2 of the additive dispensing device 100. The outlet 11 of the water supply path 1 is located on the outside of the outer shell 2, and the nozzle 500 is located outside the outer shell 2. The outlet 11 of the water supply path 1 is connected to the nozzle 500 via the conduit 600. Preferably, a window gasket 400 is provided between the opening of the water tank 200 and the clothing dispensing port on the shell of the clothing processing device. The nozzle 500 is located at the top of the window gasket 400, facing the inside of the washing drum, and opening at the bottom of the drum where it connects to the drum wall, so that the water jet from the nozzle can cover all areas of the washing drum along the axial direction. At the same time, the window gasket 400 is a cylindrical shape that can be axially extended and deformed. The two ends of the window gasket are connected to the shell and the water tank respectively, so that the water tank can be connected to the clothing dispensing port through the window gasket, thereby preventing water from flowing from the water tank into the space between the shell and the water tank.

[0063] By integrating a water supply path 1 on the outer casing 2 of the additive dispensing device 100, and directly connecting the outlet 11 of the water supply path 1 to the nozzle 500, the additive and water drawn out through the water supply path 1 are sprayed out together, thereby achieving the purpose of the additive dispensing device 100 spraying and dispensing directly from the nozzle 500 without going through the water box part of the dispensing device 100.

[0064] like Figures 1 to 13 This invention provides a method for dispensing additives into the aforementioned clothing treatment equipment. The water inlet and the added additives are mixed in the water supply circuit, and the mixture is directly sprayed into the rotating washing drum. This achieves the goal of directly dispensing the additives onto the clothes, resulting in a significant technological advancement by reducing additive loss and improving washing performance. Simultaneously, this invention also provides a control method for the aforementioned clothing treatment equipment. After the additives are sprayed directly onto the clothes in the washing drum with the water inlet, the water level H in the water tank is controlled to always be lower than the minimum height H1 of the washing drum. This allows for the use of a small amount of water that does not submerge the clothes to perform washing and other clothing treatment procedures. This ensures that throughout the entire operation of the clothing treatment equipment, the water in the water tank never comes into contact with the clothes in the washing drum. This reduces the amount of additives and water used, effectively reduces the operating time of the clothing treatment equipment, lowers power consumption, and significantly improves the clothing treatment effect. In this embodiment of the invention, the water inlet structure used by the clothing processing device to spray water into the washing drum can be any existing type of nozzle, sprayer, water inlet pipe, etc.; the sprayed water flow can be pressurized or unpressurized; of course, the sprayed water flow can be a single direct spray or multiple sprays, etc.

[0065] The above control method allows the additive mixture to be sprayed directly and evenly onto the clothes in the washing drum, so that the clothes to be washed are directly wetted by the mixture. This not only reduces water consumption during the washing process, but also allows the additive to be directly and evenly distributed on the clothes, improving the efficiency of additive use and reducing additive waste.

[0066] Example 1

[0067] like Figures 7 to 9 This embodiment introduces a control method for a clothing processing device, particularly relating to a water inlet and additive dispensing method for the clothing processing device. The clothing processing device has a washing drum for holding the clothes to be processed and a water tank for holding water, which is rotatably mounted on the washing drum. During the water inlet process of the clothing processing device, the added additive is sprayed directly onto the clothes held in the washing drum along with the water inlet flow until the water level H in the water tank reaches the set water level H' and then the water inlet stops.

[0068] Through the above-mentioned settings, the clothing processing equipment can simultaneously add additives during the water intake process, allowing the additives to be sprayed directly onto the clothing along with the water, achieving significant technological advancements such as improving additive addition efficiency and reducing the amount added. Furthermore, after the clothing is completely soaked in water, the water will flow from the washing drum to the water tank. By monitoring the water level in the water tank during the water intake process, this application can effectively determine whether the clothing is completely soaked, thereby achieving significant technological advancements such as precise control of the water intake termination point of the clothing processing equipment.

[0069] like Figure 1 and Figure 9 As shown, in this embodiment, the water level H' is set lower than the minimum height H1 of the washing drum; preferably, a heater is provided at the bottom of the water tank, and the water level H' is set higher than the height H2 of the heater at the bottom of the water tank. With the above settings, when performing washing and other garment processing procedures, the incoming water sprayed onto the garments can be used to directly wet them, thus avoiding problems such as the need for large amounts of water and high utilization rates when adding additives. Simultaneously, because the water level remains lower than the height of the washing drum throughout the entire washing and garment processing process, the garments do not directly contact the water stored in the water tank, reducing the spin-drying time and increasing the garment processing speed.

[0070] In this embodiment, the added additive is sprayed directly onto the clothes inside the washing drum along with the incoming water flow, specifically including the following:

[0071] Step S101: Water is introduced into the washing drum from the water supply line, and the water flow sprays and wets the clothes in the washing drum.

[0072] Step S102: Pump the additive into the water supply circuit;

[0073] Step S103: Water is introduced into the water supply circuit, and the water and additives are mixed in the water supply circuit. The mixture is then sprayed directly into the washing drum.

[0074] In a further preferred embodiment, during step S102, the water supply circuit stops receiving water.

[0075] Through the above implementation method, the clothing treatment equipment can directly spray the additive onto the wetted clothing using only a small amount of water, thus achieving the effect of effective additive dispensing. Simultaneously, during the above steps and additive dispensing process, the washing drum rotates around its axis, allowing the additive dispensed with the water to be directly and evenly sprayed onto the clothing distributed throughout the washing drum, thereby achieving a significant technological advancement in improving the uniformity of the mixing between the clothing and the additive.

[0076] Preferably, in this embodiment, during the water intake process and additive addition process of the clothing treatment equipment, the washing drum rotates unidirectionally around the axis at a set speed. The clothes inside the washing drum are adhered to the drum wall by the centrifugal force of the rotating washing drum and rotate synchronously with the washing drum, so that the clothes are evenly spread on the drum wall, thereby achieving significant technical progress in increasing the area of ​​the clothes and improving the uniformity of additive addition to the clothes.

[0077] In this embodiment, in step S101, the water flow from the water supply line into the washing drum stops after reaching a set value L1; in step S102, the additive is drawn into the water supply line and the amount added reaches a set value L2, and / or the additive extraction time reaches a set value t1; in step S103, the water flow into the water supply line stops after reaching a set value L3.

[0078] Preferably, in this embodiment, the aforementioned set values ​​L1, L2, t1, and L3 are preset values ​​derived from the program selected by the clothing processing equipment and / or the type and weight of the clothing to be processed in the washing drum. This enables the addition of additives of corresponding amounts and types to clothing with different parameters such as material and weight, achieving significant technological progress in intelligent and diversified control of the clothing processing process.

[0079] In this embodiment, during the water intake process of the clothing treatment device, the above steps S101 to S103 are repeated in a cyclical manner to achieve the effect of multiple additions at different nodes during the water intake process, thereby achieving a significant technical advancement in improving the efficiency and uniformity of additive addition.

[0080] Meanwhile, in this embodiment, during the above-mentioned water intake process, the water level H in the water tank is continuously detected. When the water level H in the water tank reaches the set water level H', the cycle of steps S101 to S103 is skipped and the water intake process is stopped, so that the current additive addition cycle is completed and the water intake ends after the water level H in the water tank reaches the set water level H'.

[0081] Alternatively, during the above water intake process, after each execution of step S101 and / or step S103, the water level H in the water tank is detected. When the water level H in the water tank reaches the set water level H', the cycle of steps S101 to S103 is skipped and the water intake process is stopped, so that the water intake ends directly after the water level H in the water tank reaches the set water level H'.

[0082] In this embodiment, the clothes to be treated in the washing drum are heated during and / or after the water intake process of the clothes treatment device; preferably, as follows: Figure 7 and Figure 8 As shown, after the water intake process of the clothing treatment device is completed, the clothes in the washing drum are then heated.

[0083] In this embodiment, the clothes to be treated contained in the washing drum are heated. The heating method used can be any method in the prior art, for example:

[0084] like Figure 1 and Figure 11 As shown, in this embodiment, the clothing processing device is a washing machine, etc. A heater 3 is provided at the bottom of the water tank 200 to heat the clothes to be processed in the washing drum 300. After the water intake is completed, the heater 300 at the bottom of the water tank 200 starts to work. The water level H in the water tank 200 is higher than the height H2 of the heater. The heater 3 is immersed in the water in the water tank 200 and directly heats the water flowing from the washing drum 300 into the water tank 200. The water vapor generated by heating enters the washing drum 300 and heats the clothes to be processed in the washing drum 300.

[0085] Alternatively, in this embodiment, the clothing processing equipment is a dryer, washer-dryer combo, etc., with a drying system installed outside the water tank. The drying system includes a heater, a fan, etc., that can generate a drying airflow, and an air duct that blows the generated drying airflow into the washing drum. At any point in time, such as after water intake or during water intake, the clothing processing equipment can use the drying system to heat the clothes to be processed in the washing drum. The specific process of heating the clothes in the clothing processing equipment is as follows: the drying system starts working, generating a drying airflow, which is blown into the washing drum. The drying airflow passes through the clothes in the washing drum, heating the clothes to be processed. At the same time, the hot and humid air in the washing drum can be discharged to the outside of the clothing processing equipment, or the moisture can be condensed and separated using a condenser, thus achieving the effect of reducing the humidity of the air in the washing drum and simultaneously drying the clothes (not shown in the attached drawings).

[0086] like Figure 1 and Figure 11 As shown, in this embodiment, when the clothing processing device is a washing machine or the like, a heater 3 is provided at the bottom of the water drum 200. The control method for heating the clothes to be processed in the washing drum 300 using the heater 3 is as follows:

[0087] During the process of heating the water inlet at the bottom of the water tank 200 by the heater 4 installed at the bottom of the water tank 200, the water level in the water tank 200 needs to be detected to ensure that the water level in the water tank 200 is within a set range. The set range is greater than or equal to the height H2 of the heater installed in the water tank and less than or equal to the lowest height H1 of the washing drum.

[0088] When the water level H in the water tank drops to or is about to drop to the height H2 of the heater installed in the water tank, water is added to the water tank to ensure that the heater is completely submerged in the water in the water tank when it is heating, thus preventing the heater from burning dry.

[0089] When the water level H in the water tank rises to or is about to rise to the minimum height H1 of the washing drum, the water tank drains water to prevent the water level in the water tank from being too high and flowing directly into the washing drum to soak the clothes, thereby reducing the content of the clothes additives and affecting the washing effect.

[0090] Preferably, in this embodiment, during the heating of the clothes to be treated in the washing drum, the washing drum can rotate around its axis simultaneously, so that the clothes in the washing drum are turned over and all parts of the clothes can exchange heat with the heating airflow flowing into the drum, thereby improving the heating uniformity of the clothes in the washing drum and improving the washing effect.

[0091] In this embodiment, during the water intake process and additive dispensing process of the clothing treatment equipment, the washing drum rotates around the axis at a set speed and a set rotation-to-stop ratio to improve the uniformity of contact between the clothing and the additive, thereby improving the additive dispensing efficiency and enhancing the clothing treatment effect of the clothing treatment equipment.

[0092] In this embodiment, the additive and / or the incoming water flow is directly sprayed into the washing drum from the top of the drum opening. The additive and / or the incoming water flow is sprayed from inside the washing drum towards the drum wall onto the clothes that are rotating against the drum wall. This allows the sprayed liquid to apply an external force to the clothes to adhere to the drum wall, preventing the clothes from rotating during the water intake process, thereby improving the uniformity of the mixing between the clothes and the additive.

[0093] Example 2

[0094] This embodiment differs from Embodiment 1 above in the following technical features:

[0095] like Figure 10 As shown in the figure, this embodiment introduces a control method for a clothing processing device, particularly relating to a water inlet and additive dispensing method for the clothing processing device. The clothing processing device has a washing drum for holding the clothes to be processed, and a water tank for holding water, which is rotatably mounted on the washing drum. During the water inlet process of the clothing processing device, the added additive is sprayed directly onto the clothes held in the washing drum along with the water inlet flow, and the water inlet stops when the rate of change of the water level in the water tank exceeds a set value.

[0096] With the above settings, the clothing processing equipment can simultaneously add additives during the water intake process, allowing the additives to be sprayed directly onto the clothing along with the water, achieving significant technological advancements such as improving additive addition efficiency and reducing the amount added. Furthermore, after the clothing is completely soaked in water, the water will flow from the washing drum to the water tank. By monitoring the rate of water level rise in the water tank during the water intake process, this application can effectively determine whether the clothing has been completely soaked, thereby achieving significant technological advancements in precisely controlling the water intake termination point of the clothing processing equipment.

[0097] like Figure 10 As shown in this embodiment, during the water intake process of the clothing processing equipment, the water level H in the water tank is detected in real time. When the water level ΔH in the water tank rises above the set height difference ΔH' within any set time period t, the water intake is stopped.

[0098] In this embodiment, during the water intake process of the clothing processing equipment, water intake is stopped when the water level H in the water tank reaches or is about to reach the minimum height H1 of the washing drum. Through this setting, the water level remains below the height of the washing drum throughout the entire washing and other clothing processing process, preventing the clothes from directly contacting the water in the water tank, reducing the spin-drying time and increasing the processing speed of the clothes.

[0099] like Figure 1 and Figure 10 As shown, preferably, in this embodiment, during the water intake process of the clothing processing equipment, water intake is stopped when the water level in the water tank reaches the set water level H', and the set water level H' is lower than the minimum height H1 of the washing drum; more preferably, the set water level H' is higher than the height H2 of the heater installed at the bottom of the water tank, so as to ensure that the water level in the water tank is higher than the heater after the water intake of the clothing processing equipment is completed, thereby ensuring that the heater installed at the bottom of the water tank can use the water flowing into the water tank to heat the clothes in the washing drum.

[0100] In this embodiment, the added additive is sprayed directly onto the clothes inside the washing drum along with the incoming water flow, specifically including the following:

[0101] Step S101: Water is introduced into the washing drum from the water supply line, and the water flow sprays and wets the clothes in the washing drum.

[0102] Step S102: Pump the additive into the water supply circuit;

[0103] Step S103: Water is introduced into the water supply circuit, and the water and additives are mixed in the water supply circuit. The mixture is then sprayed directly into the washing drum.

[0104] During the water intake process of the clothing processing device, the above steps S101 to S103 are repeated in a loop. During the water intake process, the water level in the water tank is continuously detected. When the difference between the current water level detection value in the water tank and the water level detection value in the water tank before the set time t exceeds the set height difference △H', the water intake process stops after the current cycle of the above steps S101 to S103 is completed.

[0105] In this embodiment, each time step S101 and / or step S103 is executed, the water level H in the water tank is detected in real time. If the difference between any two adjacent water level detection values ​​exceeds the set height difference △H', the current step is stopped, the cycle of steps S101 to S103 is skipped, and the water intake process is stopped.

[0106] Similarly, in this embodiment, in step S101, the water flow from the water supply line into the washing drum stops after reaching a set value L1; in step S102, the amount of additive drawn into the water supply line stops after reaching a set value L2 and / or the additive extraction time reaches a set value t1; in step S103, the water flow into the water supply line stops after reaching a set value L3; preferably, the set values ​​L1, L2, t1, and L3 are preset values ​​derived from the program selected by the clothing processing equipment and / or the type and weight of the clothes to be processed in the washing drum.

[0107] In this embodiment, during and / or after the water intake process of the clothing treatment device, the clothes to be treated in the washing drum can also be heated in the manner described in Embodiment 1 above, for example... Figure 11 The technical solution shown.

[0108] Example 3

[0109] like Figure 7 and Figure 12 , 13 As shown in the figure, this embodiment introduces a rinsing method for a clothing treatment device. The washing drum rotates at a set speed, causing the clothes inside the drum to adhere to the drum wall and rotate with the washing drum. Water is introduced into the washing drum, and the water flow rinses the clothes that are adhering to the drum wall and rotating with the washing drum.

[0110] The above method enables the introduction of rinsing water into the washing drum, which directly rinses the clothes inside the drum. This achieves a novel rinsing method that reduces the amount of additives in the clothes, and effectively defoams and rinses clothes that have undergone washing treatment, especially those that have undergone concentrated washing treatment with high additive content as described in Embodiment 1 or 2.

[0111] Figure 12 , 13As shown, in this embodiment, the rinsing process of the garment processing equipment is as follows:

[0112] Step S1: Control the washing drum to rotate at the set speed, causing the clothes inside the drum to stick to the drum wall and rotate together with the washing drum. The water contained in the clothes is separated and thrown out of the washing drum by the centrifugal force of rotation.

[0113] Step S2: Water is introduced into the washing drum. The washing drum rotates synchronously when water is introduced, causing the clothes inside the drum to stick to the drum wall and rotate with the washing drum. The water flow washes the clothes that are sticking to the drum wall and rotating with the washing drum.

[0114] By employing the above methods, the garment processing equipment first dehydrates the clothes during rinsing, reducing the water content and additive concentration before rinsing with water. This prevents excessive foaming caused by concentrated additives during the rinsing process, effectively defoaming garments after heavy washing. Simultaneously, by controlling the rotation of the washing drum to move the clothes against the drum wall during direct rinsing, the clothes are evenly and extensively spread out within the drum, ensuring that the rinsing water reaches all parts of the garments, thus significantly improving the rinsing effect of the garment processing equipment.

[0115] In this embodiment, in step S1, the washing drum rotates at a set speed, and after the clothes inside the drum adhere to the drum wall and rotate with the washing drum for a set time, step S2 is executed to start filling the washing drum with water.

[0116] And / or, in step S1, the washing drum rotates at a set speed, causing the clothes inside the drum to stick to the drum wall and rotate with the washing drum. When it is determined that the moisture content of the clothes inside the washing drum is lower than the set value, step S2 is executed to start filling the washing drum with water.

[0117] The above control methods can be used to determine the steps in the rinsing process by using accumulated time and / or the moisture content of the clothing, thus achieving a significant technological advancement in the effective and precise control of the rinsing process.

[0118] In this embodiment, during the rinsing process, the incoming water is sprayed directly from the top of the washing drum opening into the washing drum. The incoming water is also sprayed from inside the washing drum towards the drum wall onto the clothes that are rotating against the drum wall. This allows the sprayed liquid to apply an external force to the clothes against the drum wall, preventing the clothes from turning over during the rinsing process. This results in a significant technological advancement that improves the efficiency of washing clothes.

[0119] like Figure 12As shown, in this embodiment, in step S1, the washing drum rotates at a set speed, causing the clothes inside the drum to stick to the drum wall and rotate with the washing drum. During this process, the water that is thrown out of the washing drum flows through the water tank outside the washing drum and is discharged out through the drain pipe connected to the water tank. The outward drainage flow is detected. When the flow rate of the outward drainage flow is less than the set value, it is determined that the moisture content of the clothes inside the washing drum is lower than the set value. Then, step S2 is executed to start filling the washing drum with water.

[0120] In this embodiment, during the rinsing process of the above-mentioned clothing processing equipment, the water in the washing drum flows through the water passage on the washing drum to the external water tank. The drain control device on the drain pipe connected to the water tank is in the open state, and the water flowing from the washing drum to the water tank is directly discharged, so that no water will remain in the water tank and the water in the water tank will flow back into the washing drum and come into contact with the clothes.

[0121] It's alright, such as Figure 13 As shown in this embodiment, during the rinsing process of the clothing processing equipment, the water level in the water tank is monitored in real time. When the water level H in the water tank reaches the set water level H', and the set water level H' is higher than the height H2 of the heater, the drain valve or drain pump or other drainage control device is opened, and the water flowing from the washing drum to the water tank is directly discharged through the opened drain pipe. When the water level H in the water tank reaches or is about to reach the minimum height H1 of the washing drum, the clothing processing equipment stops adding water to the washing drum, so as to achieve automatic adjustment of the water level in the water tank during the rinsing process, thereby preventing water in the water tank from coming into contact with the clothes and also using the water to effectively seal the washing drum. Preferably, the set water level H' is lower than the minimum height H1 of the washing drum to avoid the problem of water in the water tank flowing into the washing drum and re-contaminating the clothes in the washing drum.

[0122] In this embodiment, when water is introduced into the washing drum, the water flow is directly sprayed onto the clothes inside the washing drum, and the sprayed water flow rinses the clothes that are attached to the drum wall and rotate with the washing drum.

[0123] like Figure 12 and Figure 13 As shown, in this embodiment, step S2 also includes a flipping step, which is used to flip the clothes in the washing drum to further improve the rinsing effect of the clothes.

[0124] In this embodiment, the flipping step includes the washing drum rotating at a set rotation-to-stop ratio, and the clothes inside the washing drum being flipped by the centrifugal force of the stopped washing drum.

[0125] In this embodiment, after the washing drum completes the flipping step, it continues to rotate at a set speed, causing the clothes inside the drum to stick to the drum wall and rotate with the washing drum. The incoming water flow continues to rinse the clothes that are sticking to the drum wall and rotating with the washing drum.

[0126] Preferred, such as Figure 12 and 13 As shown in this embodiment, during the rinsing process, the start point of the flipping step can be controlled based on the running time, specifically as follows: when the rinsing process reaches a set time point, the flipping step is executed. Of course, the start point of the flipping step can also be controlled using any other existing method, such as: different clothing processing programs corresponding to corresponding trigger points, or different types and / or weights of clothing corresponding to corresponding trigger points, etc.

[0127] like Figure 7 As shown, in this embodiment, the rinsing program of the garment processing equipment can be executed after the washing program of direct injection additive addition for concentrated washing of garments described in Embodiment 1 or 2 above. This ensures that after using the washing program described in the above embodiments, garments containing a large amount of additives can be rinsed in a direction that quickly reduces the amount of additives, thereby avoiding the problem of a large amount of foam being generated during the garment processing program and effectively preventing foam overflow from occurring in the drum of the garment processing equipment.

[0128] Example 4

[0129] like Figure 8 As shown in the figure, this embodiment introduces a control method for a garment processing device.

[0130] The additive is sprayed directly onto the clothes before washing;

[0131] Defoaming treatment should be applied to washed clothes;

[0132] The subsequent garment processing steps are carried out on the defoamed garments.

[0133] By defoaming the washed clothes before rinsing and other subsequent processing, problems such as excessive foam generation affecting subsequent processing procedures can be avoided, especially for clothes with high additive content after a concentrated wash cycle. This represents a significant technological advancement that prevents excessive foam generation in the drum during subsequent processes.

[0134] like Figure 12 and Figure 13 As shown, in this embodiment, the washed clothes undergo defoaming treatment, including the following:

[0135] Water is introduced into the washing drum of the garment processing equipment, and the water flow rinses the clothes inside the drum.

[0136] And / or, the washing drum rotates at a set speed, and the clothes inside the washing drum are adhered to the drum wall by centrifugal force and rotate together with the washing drum. After the additives and / or water on the clothes are separated, they flow out of the washing drum.

[0137] By using the above method, the garment processing equipment first dehydrates the garments, reducing their water content and additive dosage, and then rinses them with rinsing water. This process prevents the garments from producing excessive foam due to the presence of thick additives and effectively reduces the additive content on the garments, thus achieving an effective defoaming treatment for garments after concentrated washing.

[0138] like Figure 12 and Figure 13 As shown, in this embodiment, the washed clothes undergo defoaming treatment, including the following:

[0139] Step S1: Control the washing drum to rotate at the set speed, causing the clothes inside the drum to stick to the drum wall and rotate together with the washing drum. The water contained in the clothes is separated and thrown out of the washing drum by the centrifugal force of rotation.

[0140] Step S2: Water is introduced into the washing drum. The washing drum rotates synchronously when water is introduced, causing the clothes inside the drum to stick to the drum wall and rotate with the washing drum. The water flow washes the clothes that are sticking to the drum wall and rotating with the washing drum.

[0141] In this embodiment, during the defoaming process, the incoming water is sprayed directly from the top of the washing drum opening into the washing drum. The incoming water is sprayed from inside the washing drum towards the drum wall onto the clothes that are rotating against the drum wall. This allows the sprayed liquid to apply an external force to the clothes against the drum wall, preventing the clothes from turning over during the defoaming process of rinsing. This achieves a significant technological advancement by improving the washing efficiency of clothes and reducing the content of additives in the clothes.

[0142] In this embodiment, in step S2 above, the amount of rinsing water entering the washing drum is a set value L, which is a preset value corresponding to any or a combination of the type and weight of the clothes in the washing drum and the selected program.

[0143] In this embodiment, in steps S1 and S2 above, the washing drum maintains unidirectional rotation at a set speed. The clothes inside the washing drum are subjected to centrifugal force and adhere to the drum wall, rotating together with the drum. The additives and / or water on the clothes are separated from the clothes by centrifugal force.

[0144] In this embodiment, the step of directly spraying the additive onto the clothes for washing specifically includes the following: spraying water into the washing drum, with the additive being sprayed directly onto the clothes inside the drum along with the incoming water. Preferably, during the process of spraying water onto the clothes inside the washing drum, the water level in the water tank is always lower than the minimum height of the washing drum.

[0145] In this embodiment, after the water intake process of the clothing treatment equipment is completed and the additive is added, the washing drum rotates according to the corresponding program with a set rotation-stop ratio and rotation speed to wash the clothes in the washing drum.

[0146] In this embodiment, the process of directly spraying the additive onto the clothing for washing can be achieved using methods such as... Figures 7 to 10 The additives are added and water is introduced in the manner described in Embodiment 1 or 2 above, and the clothes are washed with a high additive content using the added additives and water. Of course, the clothes in the washing drum can also be heated before washing using the manner described in Embodiment 1 or 2 above.

[0147] In this embodiment, the subsequent garment processing procedure includes any or a combination of a washing program, a rinsing program, a spin-drying program, and a drying program. Preferably, the subsequent garment processing procedure includes, but is not limited to, a rinsing program; the rinsing program can be a conventional process of filling the water tank to the rinsing water level, which is generally higher than the minimum height H1 of the washing drum, using the incoming water flow to rinse the clothes in the washing drum to reduce the additive content; of course, the rinsing program can also adopt the rinsing method described in Embodiment 3 above, using a rinsing water flow to rinse the clothes.
