Definitions

  • the present disclosure generally relates to a method for reducing detachment of microfibres from garment in a washing cycle of a washing machine. Particularly, the present disclosure relates to a method for reducing detachment of microfibres from garment by determining a risk level of microfibre detachment based on a fabric type input by a user and a determined type of fabric. Moreover, the present disclosure further relates to a mobile terminal and a washing machine configured to perform such method.
  • microfibres are of non-organic material, which form microplastics.
  • microplastic can be a particle smaller than 5mm.
  • a conventional washing machine may be equipped with a filter to reduce the number of such microfibres in the wastewater.
  • the user has to replace the filter regularly. If the replacement of the filter is postponed or forgotten, the amount of microfibres in the wastewater may increase or the washing machine has to be programmed to not run a washing cycle until a new filter has been installed.
  • a method for reducing detachment of microfibres from garment in a washing cycle of a washing machine comprises receiving a fabric type user input specifying a type of fabric of the garment placed in the washing machine, determining a type of fabric of the garment in the washing machine, and calculating a risk level based on the fabric type user input and the determined type of fabric, the risk level indicating a risk that microfibres can be detached from the garment during the washing cycle.
  • the method further comprises, if the risk level is determined to be high, outputting information indicating to perform a dedicated washing cycle specifically adapted to reduce detachment of microfibres.
  • the dedicated washing cycle can be employed to reduce the amount of detached microfibres.
  • the risk level is above a first threshold, which indicates that there is a high risk of microfibre detachment.
  • the distinction between a low and high risk level can be made by use of a lookup table.
  • the lookup table may include risk values or risk value groups, each mapped to a risk type, such as a low risk or a high risk.
  • a result/an output may indicate a low or high risk of microfibre detachment, for example.
  • the user input can include entering or selecting, by a user, a particular fabric type, such as nylon, polyester, wool, linen, Elastane, elastomer, cotton, acrylic, or the like.
  • a particular fabric type such as nylon, polyester, wool, linen, Elastane, elastomer, cotton, acrylic, or the like.
  • the user may select the particular fabric type from a predefined list. It is to be understood that the user input can include entering or selecting a plurality of fabric types, such as if garment of different fabric types are placed in a drum of the washing machine for the next washing cycle.
  • the user input can include entering or selecting, by a user, a fabric group, such as organic or non-organic garment, or any other predefined fabric group, including numbers or characters (1, 2, 3, etc.; A, B, C, etc.), which can be interpreted as garment including one or more fabric types.
  • a fabric group such as organic or non-organic garment, or any other predefined fabric group, including numbers or characters (1, 2, 3, etc.; A, B, C, etc.), which can be interpreted as garment including one or more fabric types.
  • the user input can include entering or selecting, by a user, a washing cycle type, such as cold washing, coloured washing, hot washing, delicates, etc.
  • the user input can be understood as the intention of the user to initiate a particular washing cycle corresponding to the received fabric type.
  • the user selection may lead to an increased detachment of microfibres, although not intended by the user. It is very likely that users do not know how to reduce microfibre detachment during a washing cycle.
  • the user input is checked against the determined type of fabric and the risk (level) of an unsuitable washing cycle is calculated. Based on this risk level, the washing cycle may be changed, i.e. the user input may be overruled.
  • microfibre detachment i.e. the amount of microfibres washed out with the wastewater.
  • microfibres from garment can be fibre particles/portions with a small size down to 25 ⁇ m and even fibre particles/portions with a size down to 1.2 ⁇ m. Since the washing cycle is optimised for a minimum microfibre emission, the method further allows a prolonged life of any microfibre filter or other filter mechanisms employed during the washing cycle. For instance, the disclosed method may allow 50% to 70% prolonged life of the filter as it will not be clogged as soon as in case of regular washing cycles.
  • the risk level may be determined as low or high, or may correspond to a certain value from 0 to 10 or from 0 to 100, such as 0, 2, 5, 10, 20, 50, 80, 100 etc., wherein 0 means (almost) no risk, and 10 / 100 means a very high risk of microfibre emission (leading to a large amount of microfibre emission).
  • the distinction between a low and high risk level can be made by the first threshold or the use of the lookup table. For instance, if the risk level is above the threshold, there is a high risk of microfibre detachment, i.e. it is quite likely that the amount of detached microfibres will be high.
  • the first threshold value may depend on the kind of risk level determination. For example, if the risk level is determined on the basis of a scale from 0 to 100, the first threshold may be set between 25 and 75, preferably between 40 and 60. Such risk level determination can be achieved alternatively by a correspondingly predefined lookup table.
  • the method can further comprise receiving a hardness user input specifying a water hardness of the water provided to the washing machine.
  • the calculating of the risk level can then include calculating a risk contribution due to the specified water hardness.
  • a risk contribution can influence the overall risk (level) that microfibres can be detached from the garment during the washing cycle.
  • the risk contribution can increase or decrease the risk level.
  • a high water hardness value (hard water) may contribute to the risk level only a small amount (e.g., 0, 20 or 30 points on the 0..100 scale).
  • the risk level may even be reduced using a negative risk contribution value.
  • a medium hardness of the water may contribute to the risk level an amount of, for example, 40, 50 or 60 points on the 0..100 scale, and a small water hardness value (soft water) may contribute to the risk level with a larger amount (e.g., 90 or 100 points on the 0..100 scale).
  • risk contribution can likewise be on a 0..10 scale, for example, wherein hard water can be represented by a value of, e.g., 2, medium water (hardness) can be represented by a value of, e.g., 5, and soft water can be represented by a value of, e.g., 10.
  • the method can further comprise receiving a detergent user input specifying a detergent type used in the washing machine for the washing cycle.
  • the calculating of the risk level can then include calculating a risk contribution influencing the risk level due to the specified detergent.
  • the detergent type can identify a heavy duty detergent (HDD), a light duty detergent (LDD), a non-biodegradable detergent, or a biodegradable detergent. For instance, it has been found that a light duty detergent decreases the amount or number of microfibres generated during a washing cycle, while using no detergent as well as using an HDD increases microfibre emission.
  • an input indicating LDD may contribute to the risk level only a small amount (e.g., 0, 20 or 50 points on the 0..100 scale; or 5 on the 0..10 scale), while an input indicating HDD or no detergent may contribute to the risk level with a larger amount (e.g., 90 or 100 points on the 0..100 scale; or 10 on a 0..10 scale).
  • the risk level may even be reduced.
  • the method can further comprise determining a load weight of the garment placed in the washing machine.
  • the calculating of the risk level includes calculating a risk contribution influencing the risk level due to the determined load weight. For instance, it has been found that a low load increases microfibre emission.
  • a low load means, for example, equal to or less than 25% (quarter load) of the maximum load of the washing machine. This can, for example, correspond to 0 to 2 kg of garment.
  • a low load weight value may contribute to the risk level a large amount (e.g., 80, 90 or even 100 points on the 0..100 scale), while a medium load (25% to 50%; half load) contributes to the risk level a smaller amount (e.g., 40 or 50 points on the 0..100 scale), and a high load weight (50% to 100%; full load) contributes to the risk level the smallest amount or zero (e.g., 0, 5, or 10 points).
  • the risk level depending on the load weight can be determined by the use of a lookup table.
  • the lookup table may include risk values or risk value groups, each mapped to a risk type, such as a low risk or a high risk.
  • the lookup table can include load weight values or load weight value groups, each mapped to a load range, such as quarter load, half load or full load, or such as 0-500g, 500-1000g, 1000-1500g, etc. (up to the maximum load capacity of the washing machine).
  • an output may indicate a low or high risk of microfibre detachment.
  • the risk contribution due to the water hardness and/or the specified detergent and/or the determined load weight can be weighted.
  • a weighting such as a factoring, can be applied to the risk contribution(s).
  • the weight of each of the risk contributions can be between 0.1 and 0.3, preferably 0.2, on the 0..100 scale, or between 1 and 3, preferably 2, on the 0..10 scale when continuing in the 0..100 scale.
  • the total risk is a weighted sum of risk contribution(s) plus the risk level.
  • the risk level based on the fabric type and the risk contribution due to the water hardness and/or the specified detergent and/or the determined load weight can be weighted.
  • a weighting such as a factoring, can be applied to the risk level as well as the risk contribution(s).
  • the type of fabric has a greater influence on the resulting total risk than the other influences, such as water hardness, detergent or load.
  • the weight of the risk level (based on the fabric type) can be between 0.4 and 0.8, preferably 0.6, on the 0..100 scale, or between 4 and 8, preferably 6, on the 0..10 scale (when continuing in the 0..100 scale), and the weight of each of the risk contributions can be between 0.1 and 0.3, preferably 0.2 on the 0..100 scale, or between 1 and 3, preferably 2, on the 0..10 scale.
  • the total risk is a weighted sum of the individual risk level and risk contributions.
  • the weighting factor can be employed to bring the resulting risk level value to a 0..100 scale, the latter being compared against the threshold or used as input to the lookup table.
  • the above-mentioned values of the risk level and/or the risk contributions may be set smaller. For instance, each of the specified values may be reduced by a factor corresponding to the respectively mentioned weight.
  • the determining of the type of fabric of the garment includes determining a water absorption of the garment.
  • the water absorption of the garment can be determined, for example, by controlling the washing machine to open a water inlet to water/wet the garment.
  • the load of garment can be weighed or virtually determined when the garment is dry. Then, the water inlet is opened and the garment is wetted. This allows weighing or virtually determining the load of the wet garment. Based on the difference between dry and wet load, a fabric type can be calculated. This can include using another lookup table including a mapping between load difference(s) and garment types. It is to be understood that a combined lookup table can be used.
  • the water inlet and can be opened for a predefined period, for which a water level in the empty washing machine (specifically in the drum of the washing machine without garment) is known. Depending on the fibre of the garment, a certain amount of water is absorbed, so that the water level may differ depending on the type of fabric in the washing machine.
  • the water absorption of the garment can be determined by sensing a weight of the load in the drum of the washing machine.
  • Opening the water inlet and determining the load of garment may be performed several times after one another. This allows determination and analysis of a water absorption over time and in particular steps.
  • the determining of the type of fabric of the garment can include controlling the washing machine to operate a drum of the washing machine. This allows moving the garment, so that the entire garment is wet and absorbs water. Thus, the type of fabric can be determined more accurately.
  • the determining of the type of fabric of the garment can include detecting and analysing a power required by a motor to rotate the drum. Particularly, the more power the motor operating the drum requires, the heavier the garment is.
  • the required motor power can also be analysed in combination with the watering of the garment.
  • the risk level depending on the type of fabric of the garment may be set as low, medium or high, or may be set to a certain value, such as 20, 50, 80, 100 etc., wherein 0 means (almost) no risk, and 100 means a very high risk of microfibre emission (leading to a large amount of microfibre emission).
  • a small risk level value is set, e.g., 0, 2, 5, or 10 points on the 0..100 scale, or 0, or 2 on the 0..10 scale.
  • a higher risk level value is set, for example 10, 15 or even 20 points on the 0..100 scale, or 5, 6 or even 10 on the 0..10 scale.
  • a medium risk level value may be set between the above-mentioned values for low and high risks.
  • the method can further comprise, if the risk level is determined to be low, outputting information indicating to perform a washing cycle according to the type of fabric specified in the fabric type user input. For example, it can be determined that the risk level is below the first threshold (or the output of the lookup table indicates a small risk value), which indicates that there is a low risk of microfibre detachment.
  • the user input can be understood as the intention of the user to initiate a particular washing cycle corresponding to the received fabric type. If the risk level is determined to be low, information can be output that indicates to perform this particular washing cycle.
  • the method can further comprise, if the risk level is determined to be medium, outputting information indicating to perform a modified washing cycle that is a washing cycle according to the type of fabric specified in the fabric type user input with one or more washing parameters being modified.
  • a modified washing cycle that is a washing cycle according to the type of fabric specified in the fabric type user input with one or more washing parameters being modified.
  • the risk level may be compared to a second threshold (being below the first threshold). Thus, if the risk level (value) is between the first second threshold and the second threshold, the risk level is determined to be medium. If the risk level (value) is below the second threshold, the risk level is determined to be low.
  • the distinction between a low, medium and high risk level can be made by use of a lookup table.
  • the lookup table may include risk values or risk value groups, each mapped to a risk type, such as a low risk, a medium risk or a high risk.
  • an output may indicate a low, medium or high risk of microfibre detachment.
  • the one or more modified washing parameters can include an adapted water temperature and/or an adapted spin speed of the drum of the washing machine.
  • the one or more modified washing parameters that are adapted may further include a water level, a duration of the washing cycle, and/or a number of agitation and/or rinsing sub-cycles.
  • the water temperature can be adapted by setting a maximum water temperature to 40°C, and/or the spin speed can be adapted by setting a maximum speed to 800 rpm.
  • the method can further comprise outputting a user message to the user that a microfibre filter of the washing machine requires cleaning or replacement.
  • the outputting of the user message can include a visual indication and/or a sound output and/or a message transmission (e.g., via telecommunication means, such as a text message on a mobile telephone and/or an application executed on the mobile telephone presenting the information to the user).
  • the outputting of the user message can be based on a change of power consumption by a pump motor driving a water pump of the washing machine.
  • the power consumption of the pump motor for example, will decrease.
  • the power e.g., a current of an electric pump motor
  • changes e.g., compared to a predefined threshold value

  • the risk level is calculated in step 352 solely based on the received fabric type user input (step 312) and the determined type of fabric (step 332).
  • the method could function even without further user input and without determination of a load weight (step 334). Nevertheless, if such further user input and/or load weight determination takes place, a risk contribution(s) is/are calculated in step 354, 356 and/or 358 once the risk level is calculated.
  • the risk level may be amended based on further information.
  • particular risk contributions are calculated. For instance, a risk contribution due to the specified water hardness can be calculated in step 354, a risk contribution due to the specified detergent can be calculated in step 356 and/or a risk contribution due to a determined load weight can be calculated in step 358.
  • the load weight of the garment can be determined in step 334, for example, when the garment is placed into the drum 132. Alternatively or additionally, the load weight of the garment can also be determined during controlling the washing machine in steps 362 and 364, i.e. letting the garment absorb water.
  • the risk level as well as each risk contribution can be weighted (not explicitly illustrated in Figure 3 ), for example, to form a weighted sum of the risk level and each risk contribution, if any. Since the determined fabric type has the greatest influence on the amount of microfibres emitted during a washing cycle, the risk level can be weighted higher than the risk contribution(s).
  • the method of Figure 3 can be employed by the washing machine 100, where any user input is performed at the washing machine 100, particularly at the user input unit 120.
  • the receiving and determining steps 312 to 334 can be performed any time and in any (timely) order. This further allows grouping the corresponding tasks by the washing machine, as no interaction with the mobile terminal 150 is necessary. For instance, the calculation of a risk level and calculation of the risk contribution can take place after the receiving and determining steps 312 to 334 are completed.
  • the washing machine 100 can be used as a standard washing machine. Particularly, if the user is at the washing machine 100 and not at a mobile terminal 150, which may be spatially away from the washing machine 100, the washing machine 100 can be used in a usual manner. This includes operating the washing machine 100 also without determination of a risk level and/or risk contribution.
  • the dedicated washing cycle for reducing detachment of microfibres takes into account several washing parameters observed during testing, such as:
  • the dedicated washing cycle can be performed in accordance with the below illustrated washing parameter ranges.
  • the below table shows, for comparison, a "normal" 60 minute washing cycle, a dedicated washing cycle, and washing parameter ranges for the dedicated washing cycle.
