Description

The present invention relates to a device for processing textile products, in particular to a drying machine, a refreshment device or a washing machine with a refreshment function, said device configured to determine a textile product parameter or a program execution parameter. The invention also relates to a method for determining this parameter.

EP 1441060 A1 describes a drum-type dryer having one or more injection modules located in close proximity to the loading door of the machine and intended to inject additives into the drum, such as water vapor, detergent, flavor or disinfectant. To optimize the effect of the injected additive, it is proposed to reduce, stop or switch the direction of air flow through the drum to the opposite. The amount of additive that needs to be fed into the drum through the injection modules is set using the dosing module.

The objective of the invention is to provide a device for processing textile products with the ability to determine at least one parameter of textile products or a parameter of the program in a convenient and cost-effective way. Also proposed is a method in which a parameter thus defined is used that relates to textiles and / or program execution.

The invention is defined in paragraphs 1, 19 and 23 of the claims, respectively.

Particular embodiments of the invention are defined in the dependent claims.

In accordance with the method of claim 1, at least one textile parameter is determined in the textile processing device. Preferably, the textile processing device is a drying machine, a refreshing device, or a washing machine with a drying function. A device for processing textile products has a compartment for containing processed textile products, for example, a rotating drum used in a tumble dryer or a washing machine. In addition, there is at least one additive supply device for directly or indirectly supplying the additive to the compartment for influencing the textile products located therein. Preferably, at least one additive supply device delivers the additive in the form of steam into the compartment (Clause 29), and furthermore, or alternatively, the additive is only water or water with another additive. Although it is preferable to apply the additive to the textile products in the form of steam, at least one additive can also be supplied in the form of an aerosol or mist. The additive is not supplied in liquid form to textile products, for example, neither in the form of a liquid stream, nor in the form of drops, the size of which exceeds the size of the drops forming an aerosol. As used herein, the term “textiles” includes any type of laundry or any type of fabric.

To determine at least one parameter of textile products, at least one additive from at least one supply device is fed into the compartment and at least one fed additive interacts with the textile products located therein. In this case, the response of textiles obtained as a result of interaction with at least one supplied additive is recorded or monitored. A textile response is a signal recorded by a sensor or sensor of a textile processing device. The response signal may be, for example, a periodic detection signal, a single detection signal, a continuous detection signal, a pre-programmed detection signal (e.g., an averaged signal), a group of signals, a time-averaged signal, or the like.

The detected response is used in a determination step in which at least one textile parameter is determined by processing at least one detected response. Preferably, the textile parameter obtained or determined based on the response is a parameter of a different type than the response itself, that is, if, for example, the humidity and / or temperature of the textile products is determined as the response, then the textile parameter is not a temperature and / or humidity of these textiles.

In paragraph 1 of the claims, as an alternative or in addition to determining at least one textile parameter, a program execution parameter for subsequent processing of textile products is determined in the same way as at least one textile parameter is determined. If, for example, a determination method is used to adapt a textile product processing program that runs after a determination method or includes a method for determining a start phase, an adaptation program execution parameter is determined, which in itself depends on the characteristics of the textile products (i.e., on a parameter related to to textile products). This means that it is not in every case that it is necessary to determine the textile product parameter using the determination step and then derive the program execution parameter from the textile product parameter. Instead, a program execution parameter can be determined directly using a determination method without using a textile product parameter. However, in other cases, it is preferable to determine the textile product parameter, since the textile product processing program may require adaptation of several program parameters that are used in one or in different subsequences of the textile product processing program and which can more easily be derived from the textile product parameter instead of obtaining all execution parameters programs from the detected response of textiles.

By determining at least one textile product parameter and / or program execution parameter using this determination method, there is no need for additional sensors or detectors and / or requesting the user to enter additional commands into the textile processing device to determine textile product parameters or parameters run programs that should be used to process textile products. For example, there is no need for a weight sensor to determine the weight or amount of laundry to be processed, and there is no need to request the type of textile products from the user at the beginning of the textile processing program. In particular, when at least one additive supply device is required to supply an additive during a textile processing program, its use during the determination step does not increase the cost of manufacturing the device. In addition, you can provide a "universal" program, which should only be launched by the user and in which the parameters of textile products or the parameters of the program are automatically determined using the specified method of determination. In addition, the universal program independently adapts and eliminates damage to textiles (for example, delicate textiles such as wool), and also independently optimizes resource consumption (additive consumption or energy consumption). Both of these approaches result in optimized textile processing.

According to a preferred embodiment of the invention, the detected textile response signal (s) also includes (includes) or represents (represents) a time response (s), for example a change in time or a time characteristic. The time response expands the information base and provides the ability to obtain more parameters or more reliable parameters in relation to the properties of textile products.

In a preferred embodiment of the invention, the detected response is temperature and / or humidity related to the reaction of textiles to the supply of at least one additive. Most preferably, the moisture content of textiles is determined, in particular its time dependence, since the moisture response of textiles is a very sensitive indicator of the characteristics of textiles (i.e., parameter, textiles). In other embodiments, the temperature or humidity is determined, which also implicitly depends on the humidity of the textile products. In yet another embodiment, the reliability of determining at least one parameter of textile products is increased by determining at least two different response signals of textile products to the supply of the additive. For example, it is possible to combine air temperature and humidity of textile products in the determination step to increase reliability in determining at least one parameter of textile products.

According to a preferred embodiment of the invention, the response of textiles to the supply of the additive is determined during and / or after the supply of the additive. The above-mentioned definition of “during” and / or “after” includes one or more actions: determination of a single response signal, intermittent or periodic determination, determination at specified points in time, continuous determination, averaged determination, integrated determination, etc. For example, the absorption behavior of a textile additive during a feed and / or after a feed is monitored.

To improve reproducibility in the determination of at least one parameter of textile products or at least one parameter of program execution, it is preferable that the additive is fed at a given flow rate (for example, steam) and / or with a given temperature (for example, steam) . This includes, for example, a predetermined change in the flow rate of the additive over time, so that, for example, the flow rate of the additive at the beginning of the feed is higher than at the end of the feed, which increases the resolution of determining the response of textiles.

Preferably, at least one parameter of textile products is the number of textile products and / or their type. For example, in a textile processing program, the drying temperature or the temperature of an additive intended to be fed into textile products is very important to obtain an optimal processing result and to avoid damage to textile products. On the other hand, the consumption of resources for processing textile products depends on the number of textile products contained in the processing compartment, thus, by defining such a parameter, the processing time or the number of additives supplied during the textile processing program can be adapted depending on the number of textile products. Alternatively or additionally, conditions are determined on the surface of the textile products, for example, the rate of absorption of the additive, determined by the absorption of the additive supplied to the compartment, on the surface of the textile products. If, for example, the absorption efficiency is high, the additive delivery sequence during the subsequent textile processing program can be programmed so that the additive is delivered at a high speed for a short time, and when the absorption capacity is low, the subsequent processing program is adapted so that the additive served at a lower flow rate for a longer period of time.

In a preferred embodiment of the invention, the result of the determination is compared with representative or exemplary responses stored, for example, in a look-up table, and a match or similarity between the determined response and the reference is determined. According to the results of best fit, at least one parameter of textile products and / or at least one parameter of program execution is stored in advance. This ensures the simplicity of obtaining the required parameters based on the behavior of the previous reference response of textile products having known parameters, or for which specific parameters of program execution in subsequent processing are required. In addition or as an alternative, semi-empirical modeling is performed and fuzzy logic or neural networks are used that are appropriately programmed to assign specific parameters to specific classes of defined responses.

By repeating, at least twice, the feeding and detecting steps increase the degree of predictability or accuracy in determining at least one parameter (relating to textiles or to program execution). For example, the accuracy of detection is improved by averaging the results of the determination at several stages of the supply and / or at several intermediate phases between the stages of the supply and / or change of the response signal from one supply stage to another supply stage or from one intermediate stage to another intermediate stage. It can also be used to define additional parameters.

To improve the repeatability of the response signal and, therefore, to determine the parameter, the initial conditions of the determination method are normalized before the start of the first and / or subsequent supply steps. For example, before the first feeding step, the textiles contained in the compartment are dried to a predetermined (initial) moisture level or range.

Preferably, the supply of at least one additive is continued until a predetermined level or humidity range of textiles and / or air is reached. For example, low humidity of textile products is set as a predetermined level or threshold value, so that a subsequent textile processing program can be started at low humidity of textile products. In addition, the feed time is selected short when the predetermined moisture level or range of textiles is selected in a lower range. In a preferred embodiment of the invention, after the additive is supplied, it is absorbed by the textile products, during which the response of the textile products is determined, and at least a portion of this response is used to determine at least one textile product parameter and / or program execution parameter. At the indicated absorption stage, the humidity determination signal is not affected by humidity from the additive supply.

In preferred embodiments of the invention, an increase in time or an increase in the nature of an increase in humidity or temperature during an additive supply sequence between two levels or ranges of temperature and / or humidity is determined at least once, and an increase in time or an increase in the specified nature of the increase is processed to determine at least least one parameter. Alternatively or additionally, the time reduction or the nature of the reduction is monitored or determined after the supply sequence, and the time reduction parameter or the nature of the reduction is used to determine at least one parameter. For example, such an increase / decrease time or an increase / decrease pattern is used to determine the type of textile product. In an alternative embodiment of the invention, or in addition a series of cycles including the steps of steam supply required to achieve a given humidity of the medium and / or treatment cycles during a given period of time, are counted and also used to determine at least one parameter. For example, the number of cycles is a measure of the amount of laundry loaded into the compartment.

Preferably, the temperature and / or humidity of textiles or air is determined, for example, for air in the compartment or air passed for ventilation through the compartment. Then, the rise time is processed at the determination stage, at which the rise time provides the possibility of a much finer analysis of the response of textile products as a result of interaction with the supplied additive. The characteristic of the time curve is an indicator of the type of textile products, because different types of textiles exhibit different properties when interacting with the feed additive. For example, compared with jeans material, the textile material of towels has a significantly larger surface area that is open for exposure to additives supplied to the compartment, therefore, although linen such as towels can have the same weight as linen such as jeans, the absorption rate of the material of the towels is much higher than the absorption rate of underwear such as jeans. In another example, textiles made from synthetic or textile yarn, which, for example, can be impregnated to provide water resistance, have a much lower absorption capacity than cotton yarn consisting of a large number of strands. Thus, the rise time of the determined response signal is conveniently used to establish various types of textile products. It is also convenient to determine various surface properties of textile products, for example, pre-impregnated textile products, pre-dried textile products or pre-laundered textile products.

According to a further embodiment of the invention, textiles and / or air humidity are detected using at least two humidity sensors. Preferably, two moisture sensors are used that detect different moisture conditions of the textile products. At least two humidity sensors can be located at different places in the textile compartment or may have different gaps between their sensing surfaces (when measuring electrical conductivity). Alternatively, a single sensor can operate in various modes so that different moisture states of textiles can be detected. For example, input signals of different frequencies or voltages are supplied to the sensing surfaces of the sensor, so that different levels of sensitivity can provide an indication of different humidity states or may include different signal sections for two humidity states. Thus, using different responses of the signal of at least two humidity sensors or one humidity sensor operating in different modes, differential processing is performed, in which the differences between the two signals are included in the signal analysis and as a result more information related to the textile product parameter is obtained . For example, a type of textile product may be derived based on differences of two signals. Differences in signals can, for example, provide the ability to detect air humidity with one humidity sensor and essentially detect moisture on the surface of textiles with another moisture sensor, and / or determine humidity inside textiles with another sensor.

In accordance with claim 19, there is provided a method of operating a textile processing device in which at least one textile product parameter and / or at least one program execution parameter are determined, and then the textile product processing program sequence is adapted and / or selected (automatically) depending on at least one specific parameter of the textile product. The steps of determining at least one textile product parameter can form part of a textile product processing program, that is, a textile processing program includes a determination step and a program sequence for processing textile products. As noted above, user convenience is improved due to the possibility of reducing the number of questions when the user enters parameters, or questions when entering the parameters by the user can be completely eliminated (the choice of program options or programs). In addition, or alternatively, the number of mechanical or electrical components of the textile processing device may be reduced (for example, the number of control buttons and the amount of information displayed to the user may be reduced, or the buttons may be omitted), or other sensors that are usually necessary to determine the parameter of textile products can be excluded (for example, a weight sensor).

In particular, when the textile processing device comprises at least one additive supply device, which is then used in the software textile processing sequence, the double function or use of at least one additive supply device results in being used for the step definitions, as well as during the program sequence of textile processing.

The textile processing device according to claim 23 comprises at least one feeding device for at least one additive, a textile compartment and a control module. The control module is configured to control the operation of the textile processing device, i.e. the operation of at least one additive supply device and a detection device. During and / or after at least one steam supply sequence controlled by the control module, at least one response signal is transmitted from the detection device to the control module for processing and obtaining at least one parameter of textile products and / or program execution parameter. The advantages thus achieved have already been described above, and embodiments of the invention relating to a method for determining or to a method of operating a textile processing device are fully applicable to a textile processing device operating under the control of a control unit. In this regard, the above-described embodiments of the invention are also applicable here. On the other hand, embodiments of the invention related to the device are fully applicable to the methods.

As shown schematically in FIG. 4, in the tumble dryer 2, the laundry to be processed or dried is contained in a drum (not shown) driven by the engine 4. The speed and direction of rotation of the engine 4 can be controlled by the control unit 30 (CPU). A fan is installed in the inlet channel, which is rotationally driven by the second engine 5. During operation in the condensing mode, the air passed through the drum passes through the condenser, from which it is then sent through the heater 6 before being re-fed into the drum. The moisture content of the laundry in the drum is determined using a humidity sensor 8, made in the form of a conductivity sensor. The conductivity sensor detects the conductivity of the laundry between two metal contacts inside the drum, which are located at a distance from each other. In alternative embodiments of the invention, or in addition to the humidity sensor 8, it is possible to determine the humidity of the air flowing through the drum at a different location in the air channel, for example next to or on the fluff filter located near the drum loading door. In addition, to determine the temperature of the air inside the drum, a second temperature sensor 20 is installed in the inlet of the drum.

The additive sprayer 10 creates a stream of water supplied through a feed line into the drum. Under the control of the control module 30, a pump 12 connected to the additive sprayer 10 pumps water from a water tank (not shown) into the additive sprayer 10 in which a heating element 16 for evaporating water is installed. The power of the heating element 16 is also controlled by the control module 30, so that the steam flow rate and / or its temperature is controlled by setting the temperature in the additive sprayer 10 by heating the heating element 16 and pumping a controlled flow of water into the sprayer 10, where the water comes into contact with the heating element 16. The temperature in the spray nozzle 10 is determined next to the heating element 16 using the first temperature sensor 14.

In an embodiment of the invention, which is not shown in the drawing, the steam temperature is determined using an additional temperature sensor in the steam supply pipe, or a signal is taken from the temperature sensor 20 located near the point of steam injection into the drum during steam supply (although this signal is removed , for example, as an air temperature signal without steam supply). The steam temperature signal thus determined is also transmitted to the control unit 30 and processed to control the steam temperature, or this signal is taken into account exclusively for the control operation of the heating element 16 and thus the steam temperature, or it is taken into account as a correction signal together with the temperature signal from the first a temperature sensor 14 for controlling the operation of the heating element 16.

The control unit 30 is connected to an input panel 40 including a display 42. The user selects programs through the input panel 40, and the processing modes or status of the dryer are displayed to the user on the display 42. As will be noted below, the user input requirements here are simplified by automatic determination of the humidity of the laundry, its type of laundry and load. Thus, the user’s choice can be simplified by entering the “Start” / “Stop”, “Dry” / “Refresh” / “Dry Clean”, “Easy Ironing On / Off” and “Prevent Creasing On / Off” commands. The control unit 30 further comprises a submodule 32 that receives or transmits signals to the heating element 16, a pump 12, and a first temperature sensor 14 of the additive sprayer 10 for controlling the flow and temperature of the steam supplied to the drum. In addition, the signals of the humidity sensor 8 and the second temperature sensor 20 are processed during the drying sequence to control and optimize the drying process by appropriately controlling the heating of the heater 6, the air flow generated by the fan (engine 5), and mixing the laundry by rotating the drum (drum engine 4) ) In addition, the signals of the sensors 8 and 10 are pre-processed using a submodule 32 (for example, averaged and normalized) and fed to a reference memory 34 to obtain parameters related to the laundry (in this case, the load and the type of laundry) and program execution parameters by comparing the set of detected signals with the set of reference signals (see, for example, the table in FIG. 1 and the explanations below).

The drum dryer 2 may execute fabric processing programs such as fabric refreshment, anti-creasing processing, dry cleaning, drying, disinfection, impregnation, etc. In some or all of these programs, the energy or resource consumption and the processing result can be optimized when at least some information about the processed laundry is available. For example, information on the initial moisture content of the laundry (which can be completely dry when dry cleaned or which can be wet after loading from the previous washing procedure), information on the weight of the laundry (which can be used as a measure to supply the additive, for heating energy or for the duration subsequent processing program) or information on the type of linen (synthetic, cotton, wool, functional textile products) that can be used to optimize the processing temperature, the temperature supplied to AVOK or duration of specific routines. The laundry information is also used, for example, to adapt a subsequent processing program. For example, sequences specially optimized for linen properties are added, or sequences unsuitable for textile properties are skipped. If, for example, the properties of the laundry can be automatically obtained during the determination process, you can use the "universal" program, which automatically adapts all the processing parameters depending on the detected properties or characteristics of the laundry. An example of such a determination procedure, in which the weight (or volume) of the laundry and its type are determined as the most appropriate parameters for processing fabrics, is described below.

Figure 2 shows the behavior of the moisture response over time as a response to three sequences of steam supply. Curve S denotes the surface moisture of the laundry contained in the drum, which rotates during the steam supply sequences, as well as during the absorption sequences. When using fully dry laundry loaded into the drum at time t = 0, the control unit 30 includes an additive sprayer 10 for supplying steam to the drum, thereby increasing the moisture S on the surface of the laundry detected by the humidity sensor 8.

Steam is supplied until, for the first time, the maximum threshold value Hmax of humidity is reached at time t1a. When the threshold value Hmax is reached, the steam supply is stopped and the laundry in the drum absorbs excess moisture from the air. Surface humidity S is converted to internal humidity C (Fig. 5). The first absorption or absorption sequence occurs from time t1a to time t1b, when the detected moisture reaches a lower threshold level Hmin. When the lower threshold moisture level Hmin is reached at time t1b, steam is again supplied through the additive sprayer 10, and the surface humidity S rises from the lower threshold Hmin to the upper threshold Hmax. The steam supply at time t2a is stopped. From time t2a to t2b, the laundry absorbs moisture again, and the moisture on the surface drops from Hmax to Hmin, after which from the time t2b steam supply starts again until the upper threshold value Hmax is reached again at time t3. From time t3a, the steam supply is again stopped.

The determined humidity signal S is then processed to determine the type of laundry and the load weight of the laundry. In an example embodiment, the time periods t1 and t2 required to establish a surface moisture content from Hmax to Hmin are defined as t1 = t1b-t1a and t2 = t2b-t2a. On the other hand, the number of steam supply / absorption cycles (the number of cycles from the start of feeding from Hmax to reaching the lower threshold value Hmin after Hmax is passed) determines the load of laundry. In FIG. 2, two such steam supply / absorption cycles were performed before after the time t3, the laundry humidity did not reach the lower threshold value Hmin again due to the saturation of the laundry with moisture. In other embodiments, a maximum period of time from a point in time t = 0, for example, five minutes, three minutes, or preferably two minutes, can be set, and the number of cycles performed during that time period is counted.

As shown in FIG. 1, the time periods t1, t2 to achieve the minimum humidity threshold value Hmin, which allow determining the type of textile products, are shown as the difference between cotton and synthetic products. The number of steam supply / absorption cycles is used as a measure of the load (weight or volume) of textile products in the drum. This means that by analyzing the temporal response of surface humidity S, as shown, for example, in FIG. 2, two characteristics are obtained and adapted to the comparison scheme (FIG. 1) to determine the type of textile products and the corresponding load.

Instead of starting steam supply at time t = 0, with laundry humidity = 0%, steam supply can also be started with laundry humidity, which is preferably lower than Hmin. If, for example, wet laundry is loaded into the drum (from the previous washing program), then the laundry can be dried in a drying device until the initial humidity at time t = 0 drops below Hmin, at least below Hmax. Alternatively, if the initial humidity of the laundry is not too high, the threshold humidity values Hmax and Hmin can be shifted so that at least the maximum humidity Hmax is greater than the initial humidity of the laundry. Of course, such a shift of the threshold values Hmin, Hmax is acceptable only for a given threshold value, for example, when the initial moisture content of the laundry is below 50%, preferably below 30%, and more preferably below 20%. Otherwise, if the initial humidity is higher, the laundry is dried to an acceptable level of initial humidity, as noted above.

FIG. 3 shows another embodiment of a flowchart of a processing sequence including determination procedures mainly adaptable to the processing described with reference to the time response analysis shown in FIG. 2. At step S1, a determination procedure is started when drying the laundry loaded in the drum. Humidity is also determined at this initial stage, which usually requires some time averaging before reliable moisture values are obtained. In step S3, it is determined whether the laundry has a moisture content below a predetermined initial humidity. If not, continue drying. Otherwise, if the laundry humidity is below a predetermined initial humidity, in step S5, the drying is stopped and steam supply is simultaneously turned on using the additive sprayer 10. During steam supply, the movement of the drum continues. Typically, during the steam supply sequences and the next absorption sequence, the rotation of the drum may occur at a constant speed or may be performed in reverse mode when the direction of rotation of the drum is reversed several times. Preferably, during the steam supply and absorption sequence, the fan is stopped, i.e. there is no air ventilation through the drum. At step 7, it is checked whether the predetermined upper threshold humidity value (for example, Hmax) has been reached. If not, the processing cycle S5, S7 is repeated until a predetermined upper humidity threshold is reached, and the procedure is continued at step S9. At step S9, the generation of steam and, therefore, its supply is stopped, the drum continues its movement, and turn on the counter. In step S11, the movement of the drum continues, and the humidity of the laundry is monitored until a predetermined lower threshold humidity value (for example, Hmin) is reached. As soon as the lower threshold humidity value is reached, the procedure continues at step S13, in which the counter is stopped and a period of time between turning on and off of the counter is determined. If such a steam supply (S5) and absorption (S9) cycle is performed for the first time, the first time period (t1 in FIG. 2) is stored when this steam supply / absorption cycle is performed a second time, a second time period (t2) is stored, and etc.

If in step S11 the lower threshold moisture value (for example, Hmin in FIG. 2) is not reached or is not reached within a predetermined period of time after the meter is turned on or the step S1 is started, the steam supply / absorption cycles are stopped and the quantity is counted in step S15 steam generation / absorption cycles after the start of the determination procedure (S1). For example, the second counter counts the number of times when the procedure goes through the program sequence S13 - S5. As noted above, using the calculated time periods (step S13), the type of laundry is determined in step S19. And using the number of steam generation / absorption cycles in step S17, the amount of laundry is determined. Thus, the determination procedure comprising steps S1-S19 ends, and then a program including at least one steam supplying step for treating the laundry in the drum is executed.

Depending on the determination steps S17 and S19, the program branches into one of steps S21, S23 or S25, while in step S21 a short steam treatment is performed to minimize laundry loading, in step S23, a time-average steam treatment is performed for an average laundry load, and in step S25 performs a long steam treatment for a large or maximum load of linen. At the same time, and depending on the type of textile product, the temperature maintained during the steam treatment in steps S21-S25 is adapted depending on the type of textile product. For example, synthetic-type laundry is processed at lower temperatures of air and steam, while textiles such as cotton are processed at higher temperatures of air and steam. Thus, an optimized processing program is performed, during which an optimal processing result is achieved while optimizing resources, thereby eliminating damage to the laundry.

Figure 5 shows a timeline of moisture responses of steam supply cycles (steam supply turned on) and absorption phases (steam supply turned off). Various moisture responses are shown schematically; moisture values are not presented to scale, but only as relative values. Curve A represents the air humidity response, which, for example, is determined using an air humidity sensor mounted on the drum loading door or in the air channel (not present in the above described embodiments). Curve A represents humidity when the steam for laundry having zero moisture is turned on for the first time. This means that the air humidity before the first steam supply is zero or almost zero. As soon as the first steam supply is switched on, a very rapid increase in humidity A occurs, and curve A asymptotically approaches 100%. In the absence of any laundry in the drum, the humidity A of the air will almost stepwise change from 0% to 100% at the first moment of time after the steam has been supplied. In the presence of dry laundry, an increase occurs asymptotically due to the absorption of moisture from the air by the surface of the laundry. After the steam supply stops, the air humidity slowly drops to a relatively high level of humidity (in this case, 90% is shown), since the equilibrium between the absorption of air moisture by the linen and the evaporation of moisture from the linen leads to higher air humidity, despite lower values of the humidity of the linen. Thus, even in the absorption phase (steam supply off), the air humidity A remains high. Comparison of the first and second absorption phases shows that with an increase in the total humidity or internal humidity C of the laundry, the minimum humidity level is reached during an increase in the absorption phase with an increase in the internal humidity of the laundry, that is, in the second absorption phase, the lowest air humidity value is higher than the lowest value humidity in the first phase of absorption.

Curve S1 represents the surface humidity of the laundry, which is usually measured in the drum using conductivity measurements through the electrodes installed in the drum. Surface humidity rises more slowly than air humidity, and to much lower humidity levels, which in this case represent a given upper threshold humidity level Hmax, at which the steam supply is stopped. The upper threshold level of Hmax is set here equal to 12% of surface humidity. S1 is a time response for laundry having a low surface absorption, which means that moisture from the air is slowly absorbed. For example, this curve represents synthetic yarn or textiles having an impregnated surface. In comparison, FIG. 5 shows a second surface moisture response S2, which represents textiles such as towels having a large surface area relative to the weight of the laundry, as a result of which they have a good moisture absorption capacity from the air. It should be noted that the timeline for surface humidity S2 is compressed compared to the timeline for surface moisture S1, because due to the high degree of absorption of this type of textile products, the upper threshold value Hmax for surface humidity is reached at a later time. However, in order to illustrate the response S2 of the surface moisture, for example, the towels are normalized with respect to the timeline of the response S1 of the surface moisture (where curves A and C refer to the response S1). After the steam supply is stopped, there is a sharp decrease in the moisture response S2 due to the rapid absorption of moisture from the air by this type of laundry. Accordingly, the air humidity curve A will be different for a given type of textile product compared to the air humidity response A, and the internal humidity C of the textile product is different for this case. As can be seen, by comparing the characteristics of the surface humidity values S1 and S2, it is possible to determine the type of textile products using these various characteristics during processing to determine the type of laundry.

As mentioned above, curve C represents the internal humidity of the laundry, which is usually not determined and which means the humidity value in the center or inside the laundry, that is, in those areas of yarn or textiles that are not directly open to the surrounding air. As shown, the internal humidity or the average humidity of the laundry constantly increases over time in the steam supply and absorption phases, in which the increase during the steam supply sequences occurs to a much greater extent than during the absorption sequences. During the absorption sequences, air humidity and, mainly, moisture on the surface penetrate into or into the center of the laundry and also contribute to an increase in internal humidity.
