[0019] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.
[0020] In the prior art, stains on clothing surfaces are typically cleaned using conventional detergents in a washing machine. However, some types of stains are difficult to remove with conventional washing processes, resulting in a poor user experience. Furthermore, drying appliances such as heat pump dryers and laundry cabinets can only remove minor stains using light dry cleaning, leaving them unable to remove heavier or difficult-to-remove stains.
[0021] Reference below Figure 1-Figure 2 A cleaning patch 1 according to an embodiment of the present application is described.
[0022] The cleaning patch 1 according to the present application includes a base layer 11, an anti-diffusion layer 12 and an adsorption layer 13. The base layer 11 is the supporting layer of the cleaning patch 1 and is formed of a base material. Here, the base material can be a conventional film material or a paper foil material. For example, the base material can be one or more of a PET film, a polypropylene film material, a paper fiber film material and a tinfoil foil material. It can be formed of a single material or a composite of multiple materials. The present disclosure does not specifically limit the base material and its formation method. The base layer 11 can be in a square, circular, elliptical, trapezoidal or triangular shape, etc., suitable for sticking to clothing, and the specific shape is not further limited.
[0023] The base layer 11 includes a first region 111 and a second region 112. Specifically, the first region 111 is disposed at least partially around the periphery or edge of the base layer 11, and the second region 112 is disposed at the edge of the first region 111 near the inner side of the base layer 11. The first region 111 and the second region 112 together constitute the first side surface of the base layer 11. An adhesive material is disposed on the first region 111, and the area of the adhesive material occupies 5% to 30% of the area of the base layer 11. For example, the area of the adhesive material is 3 cm 2 , 5cm 2, 8cm 2 , 10cm 2 , 15cm 2 , 20cm 2 , 30cm 2 , 50cm 2 , 80cm 2 , 100cm 2 , 150cm 2 , 180cm 2 , 200cm 2 , 224cm 2 The area of the substrate layer 11 can be 10 cm 2 , 20cm 2 , 50cm 2 , 100cm 2 , 150cm 2 , 200cm 2 , 300cm 2 , 500cm 2 , 800cm 2 Etc. The specific area value can be reasonably set according to product requirements.
[0024] In an embodiment of the present disclosure, the peel strength between the adhesive material and the surface of the clothing is heat-sensitive, that is, the peel strength between the adhesive material and the fabric in an environment of a first preset temperature decreases by at least 30% compared to the peel strength in an environment of 20°C. Specifically, the peel strength in the embodiment of the present disclosure can be measured by using a peel tester to perform multiple peel force and separation distance tests and calculate the average value of the peel strength, or by performing a peel strength test according to the T peel strength test method of GB / T2791-1995. The present disclosure does not specifically limit the specific peel strength test method. In an embodiment of the present disclosure, the first preset temperature is the temperature when the temperature in the clothing treatment chamber rises to the drying target temperature. For example, in a low-temperature drying device, the first preset temperature can be set to 35°C or 42°C, and in a medium-to-high temperature drying environment it can be 50-60°C. At this temperature, the peel strength between the adhesive material and the clothing is significantly reduced compared to the peel strength in an environment of 20°C, and the reduction is not less than 30%, for example, 30%, 40%, 60%, or 80%. In this embodiment, the peel strength of the adhesive material in a 20°C environment is set as a benchmark value for peel strength variation, ranging from 3 to 10 N / mm, for example, 3 N / mm, 5 N / mm, 8 N / mm, 10 N / mm, etc. Thus, when the clothing enters the stable drying stage, the cleaning patch 1 will naturally fall off the surface of the clothing as the peel strength between the adhesive material and the clothing decreases. The area covered by the cleaning patch 1 can also be dried by the drying airflow, eliminating manual operation by the user and preventing the problem of partially dried clothing, providing a good user experience.
[0025] In some embodiments, a plurality of through holes are provided in the second region 112 of the base layer 11. Specifically, the diameter of the through holes is 1-5 mm, for example, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc., and the total area of the through holes accounts for 25%-75% of the total area of the second region 112, for example, 25%, 35%, 50%, 60%, 75%, etc. The diameter and surface area ratio of the through holes directly affect the ability of water and air to pass through. During the cleaning process of the dryer, the diameter of the water droplets of the cleaning medium, such as foam and water mist, is generally in the range of 0.1-5 mm. Therefore, setting the diameter of the through holes in the range of 1-5 mm facilitates the water droplets to penetrate into the clothes from the outer surface of the base layer 11, thereby fully soaking the clothes to improve the cleaning effect. Furthermore, during the drying process in the clothes dryer, airflow must pass through the base layer 11 to dry the clothes covered by the cleaning patch 1. Therefore, in this embodiment, the total area of the through holes is set to 25%-75% of the total area of the second region 112. This ensures that airflow fully passes through the cleaning patch 1 to dry the clothes. In summary, in this embodiment, these through holes extending through the second region 112 allow water and airflow on the surface of the second region 112 to smoothly pass through the base layer 1 and enter the space between the cleaning patch and the surface of the clothes, thereby improving the washing and drying effects of the clothes.
[0026] In the embodiment of the present disclosure, the diffusion prevention layer 12 is disposed on the first side of the base layer 11 and is located in the second region 112. Specifically, the diffusion prevention layer 12 can be square, circular, trapezoidal, triangular or amorphous, with an area of 1 cm 2 -75cm 2 , for example 1cm 2 , 5cm 2 , 10cm 2 , 20cm 2 , 30cm 2 , 50cm 2 , 75cm 2 The thickness of the anti-diffusion layer 12 is 0.3 mm to 5 mm, for example, 0.3 mm, 0.5 mm, 1 mm, 2 mm, 5 mm, etc. Under this size, the anti-diffusion layer 12 has a good coverage area and can store an appropriate amount of anti-diffusion agent, which is conducive to exerting a good anti-diffusion effect.
[0027] In some embodiments, the anti-diffusion layer 12 includes a fiber material and an anti-diffusion agent stored therein, wherein the fiber material includes one or more of polyurethane, polypropylene, cellulose, polyvinyl alcohol, polyacrylate, and polyacrylamide. These materials are capable of storing the anti-diffusion agent and releasing it onto the surface of clothing after being squeezed, thereby preventing detergent and stains from diffusing to the outside of the cleaning patch 1. Specifically, the squeezing force is set to an external force of at least 0.5N. This prevents premature release of the anti-diffusion agent when clothing is stacked, and the conditions for releasing the anti-diffusion agent are achieved when the clothing is tumbled.
[0028] In some embodiments, the anti-diffusion agent includes a wetting agent and water, wherein the wetting agent includes one or more of ethanol, propanol, propylene glycol, butylene glycol, glycerol, etc., the water content is 50%-99.99%, and the total concentration of the wetting agent is 0.01%-50%.
[0029] In the embodiment of the present disclosure, the adsorption layer 13 is disposed on the first side of the base layer 11 and is located in the second region 112. Specifically, the adsorption layer 13 includes a flexible porous material and a cleaning agent stored therein. The flexible porous material can be square, circular, trapezoidal, triangular, or amorphous, and its area is 0.25 cm 2 -25cm 2 , for example 0.25cm 2 , 0.5cm 2 , 1cm 2 , 5cm 2 , 10cm 2 , 15cm 2 , 25cm 2 The thickness of the adsorption layer 13 is 0.5 mm to 5 mm, such as 0.5 mm, 1 mm, 1.5 mm, 2 mm, 5 mm, etc. Under this size, the adsorption layer 13 has a good coverage area and can store an appropriate amount of detergent, which is conducive to achieving a better cleaning effect.
[0030] In some embodiments, the flexible porous material has an air permeability of 5-20 cm 3 / cm 2 s, for example, 5cm 3 / cm 2 s, 10cm 3 / cm 2 s, 20cm 3 / cm 2·s, etc.; porosity 15ppi-60ppi, such as 15ppi, 20ppi, 30ppi, 40ppi, 50ppi, 60ppi, etc. Therefore, the flexible porous material has air permeability and adsorption properties suitable for use in a clothes dryer drying environment, and can clean stains without degrading the drying function of the clothes dryer, thereby ensuring user experience.
[0031] In some embodiments, the anti-diffusion layer 12 is annular in structure, and the adsorption layer 13 is arranged on the inner side of the inner circumference of the anti-diffusion layer 12, thereby avoiding excessive thickness caused by stacking the anti-diffusion layer 12 and the adsorption layer 13, so as to ensure the air permeability and water permeability of the cleaning patch 1.
[0032] In some embodiments, the cleaning agent includes at least one of an organic solvent, a surfactant, a fragrance, and an antistatic agent. Specifically, the organic solvent includes one or more of alkanes (hydrocarbon solvents / petroleum solvents), alcohols, alcohol ethers, esters, and siloxanes, wherein the alkanes include one or more of linear or isomeric butane, pentane, hexane, heptane, octane, nonane, decane, undecane, dodecane, tridecane, and tetradecane; the alcohol solvent includes one or more of ethanol, isopropanol, n-propanol, butanol, isobutanol, amyl alcohol, isopentanol, n-hexanol, propylene glycol, and butanediol; the alcohol ether solvent includes one or more of ethylene glycol butyl ether, diethylene glycol butyl ether, dipropylene glycol methyl ether, and 3-methoxy-3-methyl-1-butanol; the ester solvent includes one or more of methyl valerate, methyl hexanoate, ethyl hexanoate, methyl octanoate, ethyl octanoate, methyl decanoate, ethyl decanoate, and methyl laurate; and the siloxane solvent includes one or more of hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane, and decamethylcyclopentasiloxane. The surfactant includes one or more of lauryl alcohol polyoxyethylene ether AEO-3, AEO-7, AEO-9, peregal O-3, peregal O-5, peregal O-7, peregal O-10, isomeric decanol polyoxyethylene ether 1003, 1005, 1007, 1009, and isomeric tridecanol polyoxyethylene ether 1303, 1306, and 1309. In the cleaning agent of this embodiment, the total concentration of the cleaning agent is 90%-99.99%, and the total concentration of the surfactant is 0.01%-10%.
[0033] The cleaning patch 1 of the embodiment of the present disclosure can be pasted on the area of clothing containing stains. The detergent in the adsorption layer 13 decomposes the stains and is adsorbed into the cleaning patch 1 by the flexible porous material. The anti-diffusion layer 12 is squeezed when the clothing is squeezed, and the anti-diffusion agent is squeezed out to prevent the stains from spreading on the surface of the clothing. As the peel strength of the adhesive material on the base layer 1 decreases during the drying process of the clothing, the cleaning patch 1 naturally falls off from the surface of the clothing, completing the entire cleaning process. Therefore, the cleaning process of the cleaning patch 1 in the embodiment of the present disclosure does not require manual operation by the user. Its structure is suitable for water and air in the cleaning process to pass through the cleaning patch 1 and directly contact the clothing. It is particularly suitable for cleaning clothes in drying equipment such as heat pump dryers, and the user experience is good.
[0034] Next, a laundry treatment device and a method of using the cleaning patch 1 according to an embodiment of the present disclosure will be described.
[0035] In some embodiments, the cleaning patch 1 of the embodiment of the present disclosure can be used in clothing processing equipment such as washing machines, washing machines and dryers.
[0036] Specifically, the washing machine or the washing and drying machine includes a housing, an outer barrel and an inner barrel structure, wherein a clothing processing chamber is formed in the inner barrel, and the clothing to be processed is placed in the clothing processing chamber. In the embodiment disclosed herein, the cleaning patch 1 is first attached to the stain on the clothing to be processed and placed in the inner barrel. Secondly, after standing in the inner barrel for a period of time, the inner barrel is controlled to rotate, and water is added to the inner barrel at the same time to soak the cleaning patch 1, so that the detergent penetrates into the interior of the clothing to decompose the stains. Thirdly, after the washing water is discharged, the temperature in the clothing processing barrel is increased by hot steam or the drying component of the washing and drying machine, and the inner barrel is rotated synchronously to allow the cleaning patch 1 to fall off naturally, until the washing process or drying process is completed, the clothing and the cleaning patch 1 are taken out to complete the stain cleaning process.
[0037] In some embodiments, the cleaning patch 1 of the embodiment of the present disclosure can be used in clothing processing equipment such as a heat pump dryer or a care cabinet.
[0038] Specifically, the heat pump dryer or care cabinet includes a clothing processing chamber and a drying system. The drying system is a heat pump drying system, which further includes an evaporator, a condenser and a compressor. In addition, preferably, the clothing processing device also includes a steam generator. In the embodiment of the present disclosure, the cleaning patch 1 is first attached to the stain on the clothing to be processed and placed in the clothing processing chamber. Secondly, after standing in the clothing processing chamber for a period of time, the clothing processing chamber is controlled to rotate; optionally, hot steam can be released into the clothing processing chamber at the same time to infiltrate the cleaning patch 1, so that the detergent penetrates into the interior of the clothing to decompose the stains. Again, after the release of hot steam is completed, the heat pump drying system is run to increase the temperature in the clothing processing chamber and dry the clothing. At this time, the higher temperature in the barrel causes the cleaning patch 1 to fall off naturally, until the clothes and the cleaning patch 1 are taken out after the drying process is completed, completing the stain cleaning process.
