[0048] Users typically use a washing machine or a washer-dryer to clean clothes to reduce or remove stains on the clothes. Generally, the user needs to place the clothes to be cleaned into a washing drum, then actively or automatically add water and detergent into the washing drum, and control the rotation of the washing drum to remove or reduce stains on the clothes to achieve the purpose of cleaning the clothes.

[0049] However, if a washing machine is used to clean clothes, the clothes will be in a wet state after cleaning and cannot be worn immediately after cleaning; and if a washer-dryer is used to clean clothes, although the clothes can be worn immediately after drying after cleaning, the addition of a clothes drying process increases the processing time of the clothes.

[0050] In order to solve the above technical problems, the present application proposes a stain removal device 10, please refer to Figure 1 , Figure 1 : is a schematic diagram of the appearance of a stain removal device provided by an exemplary embodiment of the present application. Figure 1 As shown, the stain removal device 10 may include a housing 1. The housing 1 is the outer structure of the stain removal device and is used to fix and protect the internal components. The housing 1 may be made of metal or plastic.

[0051] The housing 1 may be provided with a door 2. The door 2 is used to take out the clothes to be cleaned or put them into the drum.

[0052] A control panel 3 may also be provided on the housing 1 for the user to control the stain removal device 10 via the control panel 3. The control panel 3 may be provided with buttons, knobs or a touch screen.

[0053] See also Figure 2 , Figure 2 FIG. 1 is a schematic diagram of the structure of a stain removal device provided by an exemplary embodiment of the present application. Figure 2 As shown:

[0054] The stain removal device 10 may include a drum 4. The drum 4 is the core part responsible for completing the function of cleaning clothes.

[0055] The drum 4 can be made of ceramic, stainless steel, plastic and carbon fiber, and has certain durability and corrosion resistance.

[0056] The drum 4 can be used to place clothes to be cleaned and provide an environment for washing the clothes to be cleaned.

[0057] A cleaning groove may be provided inside the rotating drum 4. A rib may be provided inside the rotating drum 4. Providing a cleaning groove and / or ribs inside the rotating drum 4 helps to improve the cleaning effect of the clothes to be cleaned.

[0058] The drum 4 can be rotated to turn over the clothes to be cleaned. Exemplarily, the rotation speed of the drum 4 can be set to between 0 and 400 rpm.

[0059] In some embodiments of the present application, in order to allow the detergent to fully contact the clothes to be cleaned in the drum 4, the drum 4 can be controlled by a motor to rotate forward and backward.

[0060] For example, the drum 4 is controlled to rotate forward for 2 seconds and then reverse for 2 seconds, or the drum 4 is controlled to rotate forward for 3 seconds and then reverse for 3 seconds.

[0061] In some embodiments of the present application, in order to reduce the working time of the rotating drum 4, the rotating drum 4 can also be controlled by a motor to rotate forward and reverse intermittently.

[0062] For example, the drum 4 is controlled to rotate forward for 2 seconds and then pause for 3 seconds; then the drum 4 is controlled to rotate reversely for 2 seconds and then pause for 3 seconds.

[0063] In some embodiments of the present application, the laundry to be cleaned can be sterilized and deodorized by bringing the detergent into contact with the laundry to be cleaned.

[0064] In some embodiments of the present application, the stain removal device 10 may include a motor, which is responsible for providing power to the drum 4 so that the drum 4 operates.

[0065] The motor housing can be made of metal materials. For example, the motor housing can be made of cast iron or aluminum alloy to ensure the sturdiness and durability of the motor structure.

[0066] The coil of the motor can be made of copper wire, which generates a magnetic field when power is applied to drive the motor to rotate.

[0067] In some embodiments of the present application, the motor may be a brushless DC motor, a brushed DC motor, a variable frequency motor, a stepper motor, or the like.

[0068] The stain removal device 10 may include a transmission system. The transmission system may be connected to the motor and be responsible for transmitting the rotational power of the motor to the drum 4.

[0069] In some embodiments of the present application, the transmission system may transmit rotational power through belts, gears, or direct drive.

[0070] Considering that the rate at which the detergent contacts the clothes to be cleaned is limited by only controlling the drum 4 to work, in order to further speed up the rate at which the detergent contacts the clothes to be cleaned, in some embodiments of the present application, an air supply component 41 may be provided in the stain removal device 10.

[0071] See also Figure 3 , Figure 3 FIG. 1 is a schematic structural diagram of a stain removal device provided by another exemplary embodiment of the present application. Figure 3 As shown, the air supply assembly 41 is connected to the drum 4. The air supply assembly 41 can deliver air to the drum 4, so that the detergent can be quickly dispersed in the drum 4 to fully contact the clothes to be cleaned.

[0072] The air supply component 41 includes various types. For example, the air supply component 41 can be a circulation fan, a circulation heating fan, a fan, etc.

[0073] The air supply component 41 can be a fan. The fan generates airflow by rotating its own blades and delivers air to the drum 4.

[0074] The air supply component 41 can be a circulating fan. The circulating fan sucks in air and delivers it to the drum 4 by rotating its own blades.

[0075] The air supply component 41 can be a circulating heating fan. The circulating heating fan is equipped with a heating element and has a heating function compared to the circulating fan.

[0076] For example, the heating element may be an electric heater or a gas heater, which can heat the air while delivering the air to the drum 4 .

[0077] Furthermore, the air supply parameters of the air supply component 41 can be determined according to the weight of the clothes to be cleaned. The air supply parameters may include at least one of a set wind speed, a set air volume and a set temperature.

[0078] In advance, a weighing sensor may be provided at the bottom of the drum 4 or at other appropriate locations to accurately measure the weight of the laundry to be cleaned.

[0079] There are many types of weighing sensors. For example, weighing sensors can include pressure weighing sensors, electromagnetic induction weighing sensors, spring weighing sensors, and the like.

[0080] In some embodiments of the present application, in order to avoid inaccurate weight measurement of the laundry by ordinary weighing sensors, a weighing sensor with high sensitivity and high resolution may be used.

[0081] In some embodiments of the present application, the weighing sensor may be calibrated regularly to reduce errors in measurement results.

[0082] In some embodiments of the present application, the weight data of the clothes to be cleaned may also be obtained by the user inputting the weight of the clothes to be cleaned.

[0083] Specifically, the user can use an external scale (such as a platform scale or a portable scale) to weigh the clothes to be cleaned before placing them into the drum 4, and then input the weight data of the clothes to be cleaned into the clothes cleaning program of the stain removal device.

[0084] After the weight of the clothes to be cleaned is determined, the set wind speed of the air supply component 41 can be determined according to the weight of the clothes to be cleaned.

[0085] For example, the set wind speed of the air supply assembly 41 can be set between 0 and 15 meters per second. It is understood that the weight of the laundry to be cleaned is often directly proportional to the set wind speed of the air supply assembly 41. That is, the heavier the laundry to be cleaned, the higher the set wind speed of the air supply assembly 41. Conversely, the lighter the laundry to be cleaned, the lower the set wind speed of the air supply assembly 41.

[0086] Furthermore, if the weight of the laundry to be cleaned is detected to be above a first weight threshold, the set wind speed of the air supply component 41 for delivering air is determined to be a first wind speed corresponding to the first weight threshold. If the weight of the laundry to be cleaned is detected to be below a second weight threshold, the set wind speed of the air supply component 41 for delivering air is determined to be a second wind speed corresponding to the second weight threshold, wherein the second weight threshold is less than the first weight threshold, and the second wind speed is less than the first wind speed. If the weight of the laundry to be cleaned is detected to be between the first weight threshold and the second weight threshold, the set wind speed of the air supply component 41 for delivering air is determined to be between the first wind speed and the second wind speed.

[0087] It should be noted that the first weight threshold, the first wind speed, the second weight threshold and the second wind speed can be accurately determined in advance by setting multiple groups of tests and obtaining test data through the tests.

[0088] Exemplarily, the first weight threshold is set to 7 kilograms, the first wind speed is set to 12 meters per second, the second weight threshold is 3 kilograms, and the second wind speed is set to 5 meters per second; if the weight of the clothes to be cleaned is 4 kilograms, the set wind speed is determined to be between 5 meters per second and 12 meters per second, and if the weight of the clothes to be cleaned is 2 kilograms, the set wind speed is determined to be lower than 5 meters per second.

[0089] In some embodiments of the present application, data on the weight of the clothes to be cleaned A and different set wind speeds of the air delivered by the air supply component 41 can also be collected through a large number of experiments.

[0090] For example, in the case of the same clothes A to be cleaned, the air supply component 41 is controlled to supply air to the drum 4 at different set wind speeds, and the shortest time required to complete the cleaning of the clothes A to be cleaned is recorded. The set wind speed corresponding to the recorded shortest time is the optimal set wind speed corresponding to the weight of the clothes A to be cleaned.

[0091] Similarly, the optimal set wind speeds corresponding to the weights of multiple different clothes to be cleaned can be recorded in the above manner, such as the weight of clothes to be cleaned B, the weight of clothes to be cleaned C, and the weight of clothes to be cleaned D.

[0092] After sufficient test data are collected, a mathematical model can be established between the weight of the laundry to be cleaned and the set wind speed at which the air supply assembly 41 delivers air to the drum 4 .

[0093] The mathematical model between the weight of the laundry to be cleaned and the set wind speed at which the air supply assembly 41 delivers air to the drum 4 may be linear or nonlinear.

[0094] Whether a mathematical model is linear can depend specifically on the distribution and trend of the data.

[0095] After establishing a mathematical model between the weight of the clothes to be cleaned and the set wind speed of the air supply component 41 to deliver air to the drum 4, when the weight of the clothes to be cleaned is determined, the corresponding set wind speed of the air supply component 41 to deliver air can be determined according to the weight of the clothes to be cleaned.

[0096] After determining the set wind speed for the air supply component 41 to deliver air, the air supply component 41 can be controlled to deliver air to the rotating drum 4 at the determined set wind speed.

[0097] After the weight of the clothes to be cleaned is determined, the set air volume of the air supply component 41 can be determined according to the weight of the clothes to be cleaned.

[0098] For example, the set air volume of the air supply component 41 can be set to between 0 and 25 cubic meters per minute.

[0099] It can be understood that the weight of the clothes to be cleaned is often proportional to the set air volume of the air supply component 41, that is, if the weight of the clothes to be cleaned is greater, the set air volume of the air supply component 41 will be greater, and conversely, if the weight of the clothes to be cleaned is smaller, the set air volume of the air supply component 41 will be smaller.

[0100] Furthermore, if the weight of the laundry to be cleaned is detected to be above a third weight threshold, the set air volume of the air delivered by the air supply component 41 is determined to be a third air volume corresponding to the third weight threshold. If the weight of the laundry to be cleaned is detected to be below a fourth weight threshold, the set air volume of the air delivered by the air supply component 41 is determined to be a fourth air volume corresponding to the fourth weight threshold, wherein the fourth weight threshold is less than the third weight threshold, and the fourth air volume is less than the third air volume. If the weight of the laundry to be cleaned is detected to be between the third and fourth weight thresholds, the set air volume of the air delivered by the air supply component 41 is determined to be between the third and fourth air volumes.

[0101] It should be noted that the third weight threshold, the third air volume, the fourth weight threshold and the fourth air volume can be accurately determined in advance by setting multiple groups of tests and obtaining test data through the tests.

[0102] For example, the first weight threshold is set to 7 kg, the first air volume is set to 25 cubic meters per minute, the second weight threshold is 3 kg, and the second air volume is set to 10 cubic meters per minute; if the weight of the clothes to be cleaned is 4 kg, the set air volume is determined to be between 10 cubic meters per minute and 25 cubic meters per minute, and if the weight of the clothes to be cleaned is 2 kg, the set air volume is determined to be less than 10 cubic meters per minute.

[0103] In some embodiments of the present application, data on the weight of the clothes to be cleaned A and the different set air volumes delivered by the air supply component 41 can also be collected through a large number of experiments.

[0104] For example, in the case of the same clothes A to be cleaned, the air supply component 41 is controlled to supply air to the drum 4 with different set air volumes, and the shortest time required to complete the cleaning of the clothes A to be cleaned is recorded. The set air volume corresponding to the recorded shortest time is the optimal set air volume corresponding to the weight of the clothes A to be cleaned.

[0105] Similarly, the optimal set air volumes corresponding to the weights of multiple different clothes to be cleaned can be recorded in the above manner, such as the weight of clothes to be cleaned B, the weight of clothes to be cleaned C, and the weight of clothes to be cleaned D.

[0106] After sufficient test data are collected, a mathematical model can be established between the weight of the laundry to be cleaned and the set air volume that the air supply assembly 41 delivers to the drum 4 .

[0107] The mathematical model between the weight of the laundry to be cleaned and the set air volume of the air supply assembly 41 supplied to the drum 4 may be linear or nonlinear.

[0108] Whether a mathematical model is linear can depend specifically on the distribution and trend of the data.

[0109] After establishing a mathematical model between the weight of the clothes to be cleaned and the set air volume of the air supply component 41 to the drum 4, when the weight of the clothes to be cleaned is determined, the corresponding set air volume of the air supply component 41 can be determined according to the weight of the clothes to be cleaned.

[0110] After determining the set air volume for the air supply component 41 to deliver air, the air supply component 41 can be controlled to deliver air to the rotating drum 4 at the determined set air volume.

[0111] After the weight of the clothes to be cleaned is determined, the set temperature of the air delivered by the air supply component 41 can be determined according to the weight of the clothes to be cleaned.

[0112] For example, the set temperature of the air delivered by the air supply component 41 can be set to between 0 and 110 degrees Celsius. It is understood that the weight of the laundry to be cleaned is often directly proportional to the set temperature of the air delivered by the air supply component 41. That is, the heavier the laundry to be cleaned, the higher the set temperature of the air delivered by the air supply component 41. Conversely, the lighter the laundry to be cleaned, the lower the set temperature of the air delivered by the air supply component 41.

[0113] Furthermore, if the weight of the laundry to be cleaned is detected to be above a fifth weight threshold, the set temperature of the air delivered by the air supply component 41 is determined to be a first temperature corresponding to the fifth weight threshold. If the weight of the laundry to be cleaned is detected to be below a sixth weight threshold, the set temperature of the air delivered by the air supply component 41 is determined to be a second temperature corresponding to a sixth weight threshold, wherein the sixth weight threshold is less than the fifth weight threshold and the second temperature is lower than the first temperature. If the weight of the laundry to be cleaned is detected to be between the fifth and sixth weight thresholds, the set temperature of the air delivered by the air supply component 41 is determined to be between the first and second temperatures.

[0114] It should be noted that the fifth weight threshold, the first temperature, the sixth weight threshold and the second temperature can be accurately determined in advance by setting multiple groups of experiments and obtaining test data through the experiments.

[0115] Exemplarily, the first weight threshold is set to 7 kg, the first temperature is set to 80 degrees Celsius, the second weight threshold is 3 kg, and the second temperature is set to 40 degrees Celsius; if the weight of the clothes to be cleaned is 4 kg, the set temperature is determined to be between 40 degrees Celsius and 80 degrees Celsius, and if the weight of the clothes to be cleaned is 2 kg, the set temperature is determined to be lower than 40 degrees Celsius.

[0116] In some embodiments of the present application, data on the weight of the clothes to be cleaned A and different set temperatures of the air delivered by the air supply component 41 can also be collected through a large number of experiments.

[0117] For example, in the case of the same clothes A to be cleaned, the air supply component 41 is controlled to supply air to the drum 4 at different set temperatures, and the shortest time required to complete the cleaning of the clothes A to be cleaned is recorded. The set temperature corresponding to the recorded shortest time is the optimal set temperature corresponding to the weight of the clothes A to be cleaned.

[0118] Similarly, the optimal set temperatures corresponding to multiple weights of different clothes to be cleaned can be recorded in the above manner, such as the weight of clothes to be cleaned B, the weight of clothes to be cleaned C, and the weight of clothes to be cleaned D.

[0119] After sufficient test data are collected, a mathematical model can be established between the weight of the laundry to be cleaned and the set temperature of the air delivered to the drum 4 by the air supply assembly 41 .

[0120] The mathematical model between the weight of the laundry to be cleaned and the set temperature of the air supplied by the air supply assembly 41 to the drum 4 may be linear or nonlinear.

[0121] Whether a mathematical model is linear can depend specifically on the distribution and trend of the data.

[0122] After establishing a mathematical model between the weight of the clothes to be cleaned and the set temperature of the air delivered by the air supply component 41 to the drum 4, when the weight of the clothes to be cleaned is determined, the set temperature of the air delivered by the air supply component 41 can be determined according to the weight of the clothes to be cleaned.

[0123] After determining the set temperature of the air delivered by the air supply component 41, the air supply component 41 can be controlled to deliver air to the rotating drum 4 at the determined set temperature.

[0124] In some embodiments of the present application, in order to further accelerate the rate at which the detergent contacts the clothes to be cleaned, a steam device 42 may be provided in the stain removal device 10 .

Figure 4 As shown, the steam device 42 is connected to the drum 4. The steam device 42 can deliver steam to the drum 4, so that the detergent can be quickly dispersed in the drum 4 to fully contact the clothes to be cleaned.

[0126] In some embodiments of the present application, the amount of steam delivered by the steam device can be set to between 0 and 0.2 liters per minute.

[0127] The steam device 42 includes various types. For example, the steam device 42 can be a steam engine, an ion steam engine, an ultrasonic steam engine, and the like.

[0128] The steam device 42 may be a steam engine that converts water into steam using heat generated by burning fuel (such as coal, natural gas, or oil).

[0129] The steam device 42 may be an ion steam generator, which can decompose water molecules into hydroxide ions through the action of electrical energy and discharge them into the air to form ion steam.

[0130] The steam device 42 may be an ultrasonic steamer that utilizes high-frequency energy generated by ultrasonic vibration to decompose water molecules into tiny steam bubbles.

[0131] In some embodiments of the present application, the set humidity in the drum 4 can be determined according to the material of the clothes to be cleaned.

[0132] In advance, since the elasticity, electrical conductivity and thermal conductivity of clothes to be cleaned are different from each other, a fiber recognition sensor can be set in the rotating drum 4.

[0133] The fiber identification sensor disposed in the drum 4 can detect the physical properties (such as elasticity, electrical conductivity, thermal conductivity, etc.) of the clothes to be cleaned, thereby accurately determining the material of the clothes to be cleaned.

[0134] The materials of the clothes to be cleaned include various types. For example, the materials of the clothes to be cleaned include but are not limited to wool, polyester, cotton, linen, and nylon.

[0135] In some embodiments of the present application, the material data of the clothes to be cleaned may also be obtained by the user inputting the material of the clothes to be cleaned.

[0136] Specifically, before placing the clothes to be cleaned into the drum 4, the user can identify the material of the clothes to be cleaned according to the label information on the clothes to be cleaned, and then input the material data of the clothes to be cleaned into the clothes cleaning program of the stain removal device.

[0137] After the material of the clothes to be cleaned is determined, the appropriate set humidity in the drum 4 can be determined according to the material of the clothes to be cleaned.

[0138] For example, if it is determined that the material of the clothes to be cleaned is cotton and linen, the set humidity in the drum 4 is determined to be 40% based on the cotton and linen material; if it is determined that the material of the clothes to be cleaned is silk, the set humidity in the drum 4 is determined to be 30% based on the silk material; if it is determined that the material of the clothes to be cleaned is wool, the set humidity in the drum 4 is determined to be 50% based on the wool material.

[0139] In some embodiments of the present application, the set humidity in the drum 4 can be determined in combination with the weight of the clothes to be cleaned and the material of the clothes to be cleaned.

[0140] Specifically, the appropriate set humidity range in the drum 4 is determined in advance according to the material of the clothes to be cleaned.

[0141] For example, if the material of the clothes to be cleaned is cotton and linen, the set humidity range in the drum 4 is determined to be 40% to 50% based on the cotton and linen material; if the material of the clothes to be cleaned is silk, the set humidity range in the drum 4 is determined to be 30% to 40% based on the silk material; if the material of the clothes to be cleaned is wool, the set humidity range in the drum 4 is determined to be 50% to 60% based on the silk material.

[0142] After determining the appropriate set humidity range in the drum 4 according to the material of the clothes to be cleaned, the optimal set humidity within the set humidity range can be determined according to the weight of the clothes to be cleaned.

[0143] For example, if the set humidity in the drum 4 is determined to be 40% to 50% based on the material of the clothes to be cleaned, and the weight of the clothes to be cleaned is 6 kg, then the optimal set humidity in the drum 4 can be determined to be 48%; and if the set humidity in the drum 4 is determined to be 40% to 50% based on the material of the clothes to be cleaned, and the weight of the clothes to be cleaned is 1 kg, then the optimal set humidity in the drum 4 can be determined to be 40%.

[0144] After the set humidity in the drum 4 is determined, the steam device 42 can be controlled to deliver air to the drum 4 at the determined set humidity.

[0145] The stain removal device 10 may further include a detergent delivery system 6. The detergent delivery system 6 may be connected to the drum 4. The detergent delivery system 6 is capable of delivering detergent into the drum 4.

[0146] The cleaning agent delivery system 6 may include a pipeline. The pipeline can be used to transport the cleaning agent into the drum 4.

[0147] The detergent delivery system 6 may include a detergent delivery port. The detergent delivery port is an interface for manually or automatically delivering detergent to the drum 4. The detergent delivery port may be provided on the side of the stain removal device 10 so that the user can deliver detergent.

[0148] The detergent delivery system 6 may include a detergent pump. The detergent pump may be configured to pump detergent into the drum 4 in a rotary manner. The detergent pump may also be configured to pump detergent into the drum 4 in a pressure manner.

[0149] The detergent delivery system 6 may include a nozzle that can evenly spray the detergent onto the surface of the clothes to be cleaned.

[0150] In some embodiments of the present application, the physical state of the cleaning agent before being put into the drum 4 may include liquid, solid or gaseous.

[0151] In some embodiments of the present application, since the weight of the clothes to be cleaned in the drum 4 is often proportional to the amount of detergent required, that is, if the weight of the clothes to be cleaned in the drum 4 is greater, the amount of detergent required is greater, and conversely, if the weight of the clothes to be cleaned in the drum 4 is smaller, the amount of detergent required is less.

[0152] Therefore, before controlling the detergent delivery system 6 to deliver detergent, the weight of the clothes to be cleaned in the drum 4 can be obtained, and a corresponding amount of detergent can be delivered according to the weight of the clothes to be cleaned. Intelligently delivering detergent through the detergent delivery system 6 can reduce the waste of detergent resources.

[0153] The stain removal device 10 may further comprise a detergent storage system 5 , which is connected to a detergent delivery system 6 , which delivers the detergent in the detergent storage system 5 into the drum 4 .

[0154] In some embodiments of the present application, the detergent storage system 5 may be located on the top or side of the stain removal device 10 to facilitate the user to add detergent.

[0155] In some embodiments of the present application, by providing a detergent storage system 5 in the stain removal device 10, the user can save time and energy in manually adding detergent.

[0156] The stain removal device 10 may further include a discharge system 7. The discharge system 7 may be connected to the drum 4. The discharge system 7 is used to discharge the detergent mixed with the stains on the clothes after the clothes are cleaned in the drum 4.

[0157] Since the detergent delivery system 6 delivers detergent into the drum 4 so that the detergent comes into contact with the clothes to be cleaned, the stains on the clothes to be cleaned are taken away, and finally detergent mixed with the stains on the clothes is obtained.

[0158] In some embodiments of the present application, the drain system 7 may be located at the bottom or side of the stain removal device 10 to facilitate the smooth discharge of detergent mixed with clothing stains.

[0159] In some embodiments of the present application, a filter may be provided in the exhaust system 7 .

[0160] Solid particles and impurities in the detergent mixed with clothing stains are removed through a filter, so as to better treat the detergent mixed with clothing stains and reduce pollution to the environment.

[0161] For example, the filter may be a fine mesh filter, a laminated filter, a plate and frame filter, an activated carbon filter, a microporous filter, and the like.

[0162] The exhaust system 7 may include an exhaust valve. There are many types of exhaust valves. For example, the exhaust valve may be an electromagnetic valve or a manual valve.

[0163] By controlling the drain valve to open or close, the draining of detergent mixed with clothing stains can be controlled.

[0164] The drain system 7 may include a drain pipe for transporting the detergent mixed with the laundry stains to a drain port.

[0165] In some embodiments of the present application, a detergent recovery system 8 may be provided in the stain removal device 10 .

[0166] See also Figure 5 , Figure 5 FIG. 1 is a schematic structural diagram of a stain removal device provided by another exemplary embodiment of the present application. Figure 5 As shown, the detergent recovery system 8 may be provided with an adsorption module. The adsorption module may utilize specific adsorption materials (such as activated carbon, molecular sieve, etc.) to adsorb the laundry stains in the detergent mixed with the laundry stains discharged from the drum 4.

[0167] There are many types of stains on the clothes to be cleaned. For example, the stains may include oil stains, mud stains and the like.

[0168] The adsorption module is also connected to the exhaust system 7 and can discharge the adsorbed clothing stains through the exhaust system 7 .

[0169] By providing an adsorption module in the detergent recovery system 8, the clothing stains in the detergent mixed with clothing stains discharged from the drum 4 can be adsorbed, and the adsorbed clothing stains can be discharged through the connected discharge system 7, thereby obtaining the detergent with the clothing stains removed, effectively recycling the detergent, reducing the cleaning cost of the clothes to be cleaned, and reducing environmental pollution.

[0170] In some embodiments of the present application, the adsorption module may be detachable. When the adsorption capacity of the adsorption module reaches saturation, the saturated adsorption module may be detached and replaced with a new one.

[0171] In some embodiments of the present application, considering that different adsorption materials have different adsorption strengths on different clothing stains, adsorption modules with different adsorption material layers may be provided.

[0172] Exemplarily, the adsorption module has two different adsorption material layers A and B, wherein the adsorption material layer A can be used to adsorb oil stains in clothing stains, and the adsorption material layer B can be used to adsorb mud stains in clothing stains.

[0173] By providing a plurality of different adsorption material layers, the adsorption capacity of the adsorption module for clothing stains is improved, so that all clothing stains in the detergent mixed with clothing stains can be adsorbed by the adsorption module.

[0174] In some embodiments of the present application, the detergent recovery system 8 may further include a storage chamber that is in communication with the drum 4 and can store detergent mixed with clothing stains discharged from the drum 4 or detergent after the clothing stains have been removed by the adsorption module.

[0175] Specifically, the adsorption module can be set in the pipeline connecting the storage chamber and the drum 4, so that the detergent discharged from the drum 4 is the detergent after the stains on the clothes are removed by the adsorption module, and the storage chamber stores the detergent after the stains on the clothes are removed by the adsorption module.

[0176] In some embodiments of the present application, the adsorption module may be further disposed in a storage chamber that can store the detergent mixed with the laundry stains discharged from the drum 4 .

[0177] Before the detergent mixed with clothing stains in the storage chamber needs to be discharged through the discharge system 7, the clothing stains in the detergent mixed with clothing stains discharged from the drum 4 can be adsorbed by the adsorption module, and the clothing stains adsorbed by the adsorption module can be discharged through the discharge system 7.

[0178] In some embodiments of the present application, before the detergent mixed with clothing stains in the storage chamber needs to be re-delivered to the drum 4 through the pipeline, the detergent after the clothing stains are removed by the adsorption module can be re-delivered to the drum 4.

[0179] In some embodiments of the present application, the storage chamber may include a plurality of storage cavities. A first switch valve is provided between adjacent storage cavities, and the first switch valve can control the communication or independence between adjacent storage cavities.

[0180] See also Figure 6 , Figure 6 FIG. 1 is a schematic diagram of the structure of a storage chamber provided by an exemplary embodiment of the present application. Figure 6 As shown, the storage chamber includes 9 storage cavities, and a first switch valve is provided between adjacent storage cavities, so 12 first switch valves are provided.

[0181] It should be noted that the shape of the storage cavity includes but is not limited to square, triangle, and rectangle.

[0182] The first switch valves are independent of each other. For example, among several first switch valves, a first switch valve A can be controlled to be closed, and another first switch valve B can be controlled to be opened at the same time.

[0183] In some embodiments of the present application, the first switching valve may be an electric switching valve, a pneumatic switching valve, a solenoid valve, etc.

[0184] In some embodiments of the present application, an adsorption module may be provided in the storage chamber.

[0185] Furthermore, one adsorption module may be provided in one storage chamber. As in the above exemplary embodiment, nine storage chambers may be provided with corresponding nine adsorption modules.

[0186] In some embodiments of the present application, each storage cavity can be independently connected to the discharge system 7. As shown in the above exemplary embodiment, the nine storage cavities are all connected to the discharge system 7, and the detergent mixed with the laundry stains stored in their own storage cavities can be discharged through the discharge system 7 separately.

[0187] Furthermore, independent storage chambers or interconnected storage chambers can be provided according to different storage requirements.

[0188] In some embodiments of the present application, when the amount of detergent mixed with clothing stains in the storage chamber connected to the drum 4 reaches a preset value, the storage chamber can be controlled to be connected to the adjacent storage chamber through the first switching valve, thereby obtaining excess storage space to store the detergent mixed with clothing stains.

[0189] In some embodiments of the present application, in order to avoid storing different types of detergents mixed with clothing stains in the same storage chamber, thereby causing difficulties in the recovery of the detergents, the storage chambers can be controlled to be independent of each other through a first switch valve.

[0190] For example, when a laundry cleaning instruction for this round is received, the laundry to be cleaned this round is dry-cleaned, detergent A mixed with laundry stains is obtained, and the detergent A is stored in storage chamber A. When a laundry cleaning instruction for the next round is received, the laundry to be cleaned next round is dry-cleaned, detergent B mixed with laundry stains is obtained, and the detergent B is stored in storage chamber B.

[0191] Since the clothes to be cleaned in different rounds of dry cleaning are different, the detergents mixed with the stains on the clothes are often different. For example, in the embodiment shown above, the detergent A mixed with the stains on the clothes is different from the detergent B mixed with the stains on the clothes.

[0192] Thus, different types of detergents mixed with clothing stains can be stored in different storage chambers, thereby facilitating the recycling of different detergents mixed with clothing stains.

[0193] In some embodiments of the present application, a second on-off valve is further provided between the storage chamber and the drum 4. The second on-off valve can control whether the detergent, after the adsorption module has removed stains from the clothes, is discharged into the drum 4 or stored in the storage chamber. The storage chamber can also be in communication with the drum 4.

[0194] In some embodiments of the present application, the second switch valve may also be an electric switch valve, a pneumatic switch valve, a solenoid valve, etc.

[0195] The detergent after the stains on the clothes are removed by the adsorption module is controlled by the second switch valve to be discharged to the drum 4 or stored in the storage cavity, thereby facilitating the control of the detergent after the stains on the clothes are removed according to different usage requirements.

[0196] Specifically, if the second switch valve is controlled to be open, the detergent after the stains on the clothes are removed is discharged to the drum 4; if the second switch valve is controlled to be closed, the detergent after the stains on the clothes are removed is stored in the storage chamber.

[0197] For example, if the user needs to dry clean the next round of laundry, the second on-off valve can be controlled to open to discharge the detergent after the adsorption module has removed the stains from the laundry into the drum 4. If the user does not need to dry clean any laundry at this time, the second on-off valve can be controlled to close to store the detergent after the adsorption module has removed the stains from the laundry in the storage chamber, waiting for subsequent use of the detergent after the stains have been removed from the laundry.

[0198] The stain removal device 10 may include a controller.

[0199] The controller can be electrically connected to the drum and the detergent delivery system 6. The controller can control the drum 4 to work; the controller can control the detergent delivery system 6 to deliver detergent.

[0200] The controller can also be electrically connected to the discharge system 7. The controller controls whether the discharge system 7 discharges the laundry stains or the detergent mixed with the laundry stains.

[0201] The controller can also be electrically connected to the air supply assembly 41. The air supply assembly 41 is controlled by the controller to deliver air to the rotating drum 4.

[0202] Furthermore, the air supply parameters of the air supply component 41 that delivers air to the drum 4 can be controlled by the controller.

[0203] The controller can also be electrically connected to the steam device 42. The steam device 42 is controlled by the controller to deliver steam to the drum 4.

[0204] Furthermore, the steam parameters of the steam device 42 for delivering steam to the drum 4 can be controlled by the controller.

This application is intended to cover any variations, uses, or adaptations of the present application that follow the general principles of this application and include common knowledge or customary techniques in the art that are not disclosed herein.
