Description

The invention relates to a device for processing textile products and a method in which the processed textile products are loaded into a drum, and the loaded textile products can be processed in accordance with a regeneration cycle, a drying cycle and / or an anti-crease cycle.

EP 1852539 A1 discloses a dryer and drying method using an anti-crease cycle and optionally an extended anti-crease cycle after the main drying cycle. In the anti-crease cycle and the extended anti-crease cycle, hot water vapor is supplied to the drum into which the textile products are loaded. The steam supply during the anti-creasing cycle maintains the characteristics of textiles achieved after the main drying cycle. Supporting or preserving the characteristics of textile products means that during storage (anti-crease program) or long-term storage (extended anti-crease program), additional wrinkles are not formed on the textile products.

The aim of the invention is to further optimize the results of the drying cycle, the regeneration cycle and / or anti-creasing cycle for processed textiles.

The invention is described in claims 1 and 24 of the claims, respectively.

Particular embodiments are disclosed in the dependent claims.

Figures 1A to 1C illustrate the original idea of the inventors, where textiles are processed in a rotary drum in a dry mode (without adding liquid) in a processing device such as a washing machine with a drying function or a drying machine. The axis of rotation of the drum 2 is not vertical, i.e. horizontal, almost horizontal or has an angle of inclination in the range of ± 45 ° with respect to the horizontal. Several units of laundry 6 are located in the inner space 5 of the drum 2 and the surface of the laundry 6, exposed to ambient air from the inner space 4, exchanges humidity and temperature with the outside atmosphere. The higher the ratio of the open surface of the laundry to the invisible or closed surface, the higher the exchange of humidity and temperature between the environment and the surface / volume of textiles. On figa shows an example where the drum 2 rotates at a high speed of rotation. At this rotation speed, the movement of the laundry 6 in the orbit is achieved, that is, the laundry 6 adheres to the inner surface of the drum and does not fall under the action of gravity even at the upper turning point of the drum.

FIG. 1B shows a state at an average drum rotation speed. When the laundry moves upward from the lower point of the drum, the laundry is constantly separated from the inner wall, and the centrifugal force is so small before reaching the upper turning point of the drum that the laundry freely falls inside the inner space 4 to almost half of it. As shown by the internal arrows, the area affected by the surrounding atmosphere in the inner space 4 is maximum in FIG. 1B due to a decrease in the contact area with the inside of the drum and a decrease in the contact area between adjacent laundry surfaces.

On figs shows the position when the rotation speed of the drum is even lower. In this case, the centrifugal force is small, and the laundry is separated at an earlier angle, starting from the bottom of the drum so that the laundry rolls down from the ascending part of the inner wall of the drum. The laundry is rolled up, and only a small part of the surface is affected by the surrounding air, while the surfaces of the laundry are substantially in contact with each other.

In addition, it was found that the ideal state depicted in FIG. 1B is not always achieved at the same rotation speed even if a drum 2 with the same diameter and internal surface area is used:

a) With the same load of laundry (type and weight of textiles) wet laundry behaves, as shown in figv, at a specific speed. If a specific speed is maintained, but the laundry is wet, it behaves as shown in FIG. 1C. If, on the other hand, the laundry is dry, it behaves as shown in FIG. 1A.

b) Considering the same type of textile with fixed humidity, the average load or volume of textile products at a particular rotation speed will lead to the flipping mode shown in FIG. 1B. If more laundry (the same type of textile and the same humidity) is loaded into the drum 6, the mode shown in FIG. 1A is achieved. When the load of laundry is reduced compared to FIG. 1B, a roll-up mode is achieved, as shown in FIG. 1C.

c) When, as shown in the third example, various types of textiles are used while maintaining the weight and moisture of the laundry, the wool will behave according to the mode of FIG. 1B, while the denim will roll off the inner wall, as shown in FIG. 1C. Finally, towels will adhere to the inner wall of the drum, as shown in FIG. 1A.

The device for processing textile products according to claim 1 of the claims includes a control unit for controlling at least one programmed processing cycle. Preferably, when the control unit has access to many different program processing cycles in accordance with the choice of the user and / or activated depending on the user selected software options and / or automatically determined initial conditions. The program processing cycle may be a program drying cycle, a program regeneration cycle (e.g., dry cleaning), or a program anti-crease cycle. A program processing cycle may be one of these cycles or a combination of these cycles. A complete combination of a programmed treatment cycle is, for example, a drying cycle, then a regeneration cycle, and finally an anti-creasing cycle. Optionally, an extended anti-crease program cycle may be added, as is known from EP 1852539 A1.

The textile products to be processed (linen / clothes) are loaded into the drum of the textile processing device, in which the axis of rotation of the drum is preferably horizontally, practically horizontally or inclined to the horizontal at an angle in the range of ± 45 °. The drum is driven by a drive unit. By means of the drive unit, the drum can rotate forward, more preferably, when it can also rotate in the opposite direction. The start and end of rotation is controlled by a control unit that provides the appropriate control signals for rotation / stop of the drive unit. Thus, the control unit controls the start and end time of rotation, which is indicated by the duration of the periods of rotation of the drum and the periods of stop of the drum. In a preferred embodiment, the control unit also controls the direction of rotation (forward / reverse). Preferably, the driving periods in the forward / opposite direction are independently controlled.

The control unit of the device for processing textile products is configured to change the rotation mode of the drum depending on the type of textile products, humidity of textile products or the weight of textile products. Or, the change is made depending on two or all of these parameters of textile products. The rotation mode of the drum is sometimes called mechanics, i.e. (physical) mechanical action exerted on the textile by rotating the drum. The mechanics are affected by the rotation speed (of course, it is assumed that the drum as such is unchanged), the ratio of the periods of rotation of the drum to the periods of stop of the drum, and the ratio of periods of rotation of the drum forward to periods of rotation of the drum in the opposite direction.

As mentioned above, when the drum rotates, the rotational speed of the drum is optimized depending on the type of textile, humidity and / or weight of the textile to achieve the preferred ideal flipping mode, as shown in FIG. 1B. In FIG. 1B, the mechanics of textiles cannot be avoided (laundry 6 adheres to the inner wall of the drum and falls onto the inner wall at the bottom of the drum after free fall), however, the interaction of the surface with the surrounding air is maximized. In contrast, the mechanical impact on textiles in the roll-up mode is high, as shown in FIG. 1C. In the mode shown in FIG. 1A, the orbital speed is achieved so that there is no mechanical load on the laundry, however, the increased centrifugal force, in particular at the lower pivot point of the drum 3, causes the formation of folds due to compression. In addition to optimizing the rotation speed, the mechanical load on the laundry can be reduced due to the lack of rotation of the drum (periods of stopping the drum). However, in this case, wrinkling is enhanced. Thus, it is necessary to redistribute the textile products in the drum so as to achieve uniform interaction between the surface of the laundry and the surrounding atmosphere for uniform processing of loaded textile products.

According to a preferred embodiment, the textile processing apparatus includes a feed unit for supplying the additive to the drum. Preferably, when the additive is applied directly to the drum in order to enhance the effectiveness of the interaction of textiles and the added additive. Preferably, the drum rotation mode is modified at least during the steam supply cycle, preferably only in the additive supply cycle, or most preferably only during the additive supply phase. The additive supply cycle can be a full programmed processing cycle, it is preferable that this is only a programmed regeneration cycle and / or a programmed anti-crease cycle, more preferably if it is only part of it. The additive delivery phase is the phase during which the additive is actually fed into the drum. For example, the additive supply cycle may include one or more periods or phases that do not completely exhaust the cycle during which the additive is fed to the drum.

The type of textile products to be processed is determined automatically by the unit for determining the type of textile products of the processing device and / or in a preferred way, the type of textile products is selected by the user in advance or when the program processing cycle is started. Preferably, the rotational speed of the drum and / or the ratio of the periods of rotation of the drum to the periods of stop of the drum is increased for delicate or durable denim textiles or certain types of synthetics. Thus, the interaction of the surface of textiles and the surrounding atmosphere is more active (maximum) in the normal mode of rotation of the drum. The term “higher” refers here to the nominal or normal rotation speed and / or the rotation / stop ratio (occupancy rate) established for “ordinary” textile products. Common textiles, for example, are T-shirts, sweaters, or casual shirts. Additionally or alternatively, the rotational speed of the drum and / or the ratio of the periods of rotation of the drum to the periods of stop of the drum is reduced or reduced for delicate textiles, for example, woolen, business or silk textiles. Thus, the mechanical effect on delicate textiles is significantly reduced.

According to an embodiment, the processing device includes a unit for determining the weight of textile products loaded into the drum and / or input unit, so that the user can enter an approximate weight or volume of textile products (the latter as a measure of the weight of textile products). In an embodiment, the moisture determination value can be used to calculate the average dry weight of the laundry based on the identified type of textile or entered based on the weight or volume entered by the user.

In a preferred embodiment, the activation or start of a specific processing cycle is not allowed if the specified weight or volume value is exceeded. For example, the regeneration and / or anti-creasing cycle does not start and a failure to start is preferably displayed to the user. Such a ban is imposed because a good quality of regeneration and / or anti-crease processing can be achieved only when the drum is not fully loaded, or when the laundry is not too heavy.

In a preferred embodiment, the rotational speed of the drum and / or the ratio of the periods of rotation of the drum to the periods of stop of the drum increase (decrease) with more (less) weight or quantity of textile products. If there are more textile products in the drum or they have a lot of weight, textile products need to be mixed or redistributed more intensively or more often to achieve uniform processing of loaded textile products.

In a preferred embodiment of the above-described variants, the drum rotation speed and / or the ratio of the drum rotation period to the stop periods are adjusted depending on the humidity value of the textile products, where a higher speed and / or higher ratio are set for higher humidity values, while at lower humidity values they are reduced. Preferably, when the rotational speed of the drum and / or the ratio changes from time to time constantly or at specific points during the treatment cycle to adjust to the changing humidity of the textile products. When, for example, a drying cycle is carried out and the drying process is underway, the weight of the laundry and, consequently, the mixing mode (sticking / rolling / folding - compare figa-1C) changes in time. Optimum washing quality can be achieved by reducing the mechanical effect on the laundry with a decrease in humidity.

Preferably, the special program cycles are activated only after the initial moisture content of the textile products is set, or it was reached as a result of the previous program drying cycle. If the detected moisture content of textiles is too high, the drying program cycle is activated automatically by the control unit.

In a further embodiment, if it is determined that the initial humidity has a predetermined humidity value of textile products or exceeds it, the control unit does not operate a specific textile processing cycle, for example, a regeneration program cycle. In this case, the control unit assumes that the textile products (laundry) were washed before the start of the processing program, and that the regeneration of textile products is not required, since the textile products have already been cleaned (dry cleaning is not required after wet cleaning).

In an embodiment, the change in the rotation mode of the drum is made depending on one or more of the following program parameters: the duration of the processing program (elapsed time of the program); the duration of the program cycle of processing (elapsed time of the program cycle); or a change is made when a transition from one program cycle to another program cycle of at least one processing program is performed (for example, the mechanical mode may remain unchanged in each of the program processing cycles, but may change from the program cycle to the program cycle). Preferably, the change (s) includes (s) one or more of the following changes: spin-on occupancy ratio (ratio of drum rotation time / drum stop time, considered, for example, from period to period, as an average over time, from cycle to cycle, elapsed time, and etc.); forward rotation / reverse rotation ratio (considered, for example, from period to period, as an average over time, from cycle to cycle, elapsed time, etc.); maximum and / or average rotation speed; and the repeatability of the rotation cycle (for example, from period to period or during the time of the program (cycle)). The change in time (at least in part of the time of the program or cycle) can be performed continuously or monotonically increasing / decreasing, or in the form of modifying steps or cycles of changes.

The above explanation is applicable to a device for processing textile products as well as a processing method, where in a device for processing textile products the steps of the method are applied by executing a processing program by a control unit. Those. the control steps performed by the control unit of the device can be considered as representing the steps of the method and vice versa.

Further, the description of the invention, a “processing program” defines a complete program executed in a processing device or installed in a manner - from the moment of starting (for example, starting by a user or under the control of a timer) to completion (there are no further program steps and the laundry processing is completed). A processing program may be divided into program processing cycles or may include only one program processing cycle. Examples of programmed processing cycles: pre-treatment, drying, regeneration, anti-crease cycle, extended anti-crease cycle, or similar program cycles. Each or at least several program processing cycles have program phases or periods, which may be different phases or periods or periodically repeating phases or periods. For example, a program regeneration cycle has periods or phases of steam supply and phases or periods when steam is not supplied.

The following are preferred embodiments of the invention described in detail, embodiments of which are illustrated by the following accompanying drawings and tables, which show:

Figure 2 shows a block diagram of the functional elements of the machine 10 for regeneration. Essentially, the regeneration machine 10 is based on a drying machine having a steam supply unit 24 for supplying steam inside the drum 2. It is understood that the regeneration machine 10 can be implemented in the washing machine with a drying function in the form of temporarily ventilated air through the drum 2. Embodiment 2 shown also has an optional special function and circuitry that the drum 2 and the blower 16 for blowing air through the drum 2 can be driven independently by the drive unit 14. In this case, there is the advantage that, for example, during the steam supply phase (when steam is sprayed or supplied inside the drum 2 from the steam supply unit 24), the air flow through the drum stops or is significantly reduced. Thus, the steam is stored in the inner space 4 of the drum and is not blown out of the drum 2. In an alternative embodiment, a single-drive motor and a blower are used for the drum; and the blower and the drum are driven in the direction of rotation alone by the motor, where the blowing power of the blower air is substantially calculated or reduced compared to the forward rotation direction or the normal rotation direction. In yet another embodiment, a clutch or other disconnecting device is provided for decoupling the rotation of the blower and the rotation of the drum during the steam supply phases.

The preferred regeneration machine 10 has a condenser unit 18 and can be controlled as a condenser type dryer where air circulates inside the regeneration machine 10 and moisture condenses in the air passage where the condenser element of the condenser unit 18 is located. Of course, the regeneration machine 10 can also be implemented as a hood dryer, where moist air is discharged from the body of the regeneration machine. A machine for regenerating a mixed — condenser and exhaust — type can also be implemented.

The execution of program drying cycles, regeneration cycles, anti-creasing cycles and extended anti-creasing cycles is regulated by the control unit 12, which receives diagnostic signals and transmits control signals to slave units of the machine 10 for regeneration. The humidity sensor 20 is located on the drum 2 and determines the humidity of the laundry by measuring the conductivity of the laundry 6. This gives the advantage that the humidity can be detected when the turbine of the drum is stopped, or when there is no air flow through the drum 2. The signal of the humidity sensor 20 is transmitted to the control unit 12 for processing at the beginning and during the execution of program cycles using the humidity value as an input signal.

The steam supply unit 24 is also regulated by the control unit 12, where one or more heaters are activated and deactivated to convert water to steam by heating. Also, the water level signal of the water tank associated with the steam supply unit 24 sends a signal to the control unit 12 so that the heating can be stopped if the water level is below a predetermined value. The water pump unit 22 is also regulated by the control unit 12, where the water pump unit 22 is located on the condenser unit 18 for collecting condensed water. The control unit 12 drives a pump for injecting condensed water from the storage tank of the water pump unit to the water tank of the steam supply unit 24 when a predetermined water level in the tank of the water pump unit is reached or after the completion of a program cycle (for example, a drying program cycle).

The additional additive supply unit 26 provides, in addition to the steam from the steam supply unit 24, the supply of the processing agent to the drum 2, preferably by means of a separate supply line and a spray nozzle so that the processing agent does not come into contact with the hot steam supplied by the steam supply unit 24. The additional additive supply unit 25 may supply one or more processing agents, for example, perfumes, dry cleaning agents, disinfectants, bleaches, and the like.

The display 28, located on the front panel of the machine 10 for regeneration, displays for the user the current state of the program and the selected options (automatically by the control unit or the user). Using the input panel 30, the user enters the selected program for processing laundry loaded into the drum and options that are activated or deactivated depending on the user's preferences. As potential regeneration programs, the user can, for example, activate programs for dry wool regeneration (without steam), dry silk regeneration (without steam), conventional steam regeneration (with steam), steam regeneration of wool, steam regeneration of delicate fabrics or steam regeneration of everyday clothes. Such selected programs include the type of processing to be performed, the regeneration machine 10, and the type or class of textile products to be processed. For example, steam regeneration of casual wear is designed for textiles such as sweaters, durable shirts, casual shirts, etc. Conventional steam regeneration is optimized for laundry where wrinkles or bends need to be removed, and which is immune to high mechanical stress during processing. Steam regeneration of cotton, for example, for denim, implies a maximum mechanical load on the linen. Refreshment of business clothes or reduced steam regeneration is intended for delicate washing, for example, woolen jackets or loose outerwear.

Additional programmatic entries made by the user via the input panel 30 can be, for example, activation or deactivation of an extended anti-crease program, which can complement the anti-crease program cycle in combination with a specific program processing cycle. The user can also optionally activate pre-drying if, for example, clothes or laundry for hand washing or wet laundry are loaded in the drum 2.

In addition, the control unit 12 controls the air heater 32 located in the air channel upstream of the flow of the drum 2 to heat the air pumped into the drum 2. Heating the air, for example, is required for a drying program cycle or when the laundry loaded in the drum 2 needs to be heated to a predetermined temperature before steam is supplied to the drum during steam supply periods. The temperature of the air leaving the drum 2 is determined by a temperature sensor 34, the signal of which is sent to the control unit 12. An optional weight sensor 36 is added, which in this case is connected to the drive unit and determines the power required to start the rotation of the drum. From the value of the power required by the engine to drive the drum 2, it is possible to calculate how high the torque caused by the loaded laundry, which in turn depends on the weight of the laundry. A weight sensor 36 is optional, and instead, an input panel 30 may provide a choice of weight or volume of laundry. For example, a user selects a minimum, medium, or maximum option for a small, medium, or large volume of laundry to be loaded.

FIGS. 3A-3C show various mechanical modes of drum movement depending on the type of textile, where FIG. 3A shows the drum movement over time for delicate textiles, FIG. 3B for normal susceptibility textiles in FIG. 3C for durable textiles. The movements of the drum are shown by continuous lines, respectively, and in these embodiments, rotation is performed forward (positive numbers) and in the opposite direction (negative numbers). In the diagrams, the abscissa axis shows time and the ordinate axis shows the relative rotation speed and relative steam flow rate, indicated by dashed lines. Relativity with respect to normalized rotational speed refers to the nominal or normal rotational speed, which usually develops during the drying mode for drying textiles. For example, the nominal rotation speed is 50 revolutions per minute, so that point 75 in FIG. 3A displays the maximum rotation speed of about 37 revolutions per minute, and point 5 in FIG. 3C displays the rotation speed of 77 revolutions per minute. By comparing figures 3A-3C, it can be seen that the maximum drum speed is reduced compared to the normal maximum speed for delicate textiles, while increased for durable textiles compared to the mode selected for conventional textiles. In addition, the duration or time or busy factor of rotation on / off, i.e. the ratio of the periods of rotation of the drum to the periods of stop of the drum increases, starting from delicate products to normal and durable products. As a result, the mechanical load on delicate textiles is reduced by choosing a reduced rotation speed and a shorter rotation cycle, while for stable textiles, the mechanical load is increased by increasing the rotation speed and the duration of the rotation cycle. 3A, the on / off rotation occupancy rate is illustrated for the first full period, where the ON 1a and ON 1b intervals should be summed for the ON time and divided by the OFF time, which is the sum of the OFF 1a and OFF 1b periods. It should be noted that the embodiment illustrated in FIGS. 3A-3C is optimized to minimize the mechanical load on the laundry depending on its susceptibility / immunity. Optimization with respect to the maximum contact of the surface with the surrounding atmosphere, as described for FIGS. 1A-C, is not considered here under any circumstances. However, such optimization can be provided for the modes shown in FIGS. 3A-3C at the same time if, for example, the user is prescribed or recommended to load or the amount of textile loaded in the drum when loading the drum of the regeneration machine. For example, the user is advised to use only a small amount of delicate textile or a small load of textile when using delicate textile in the processing cycle shown in figa. On the other hand, it is recommended for the user to load more textiles into the drum (more volume or more weight) when durable textiles are processed in the processing cycle shown in FIG. 3C.

3A-3C also illustrate a steam flow rate normalized to the steam flow rate used in conventional textile processing, as shown in FIG. 3B. This means that for delicate textiles, the steam flow rate decreases, however, the busy cycle during steam supply is longer compared to the processing cycle for conventional textiles (FIG. 3B). In the processing cycle for sustainable textiles (FIG. 3C), the duration of the steam supply cycle is also increased, starting from the processing of conventional textiles, and the steam flow rate is also increased. This means that the average steam flow rate is higher for sustainable textiles compared to ordinary and delicate textiles, and the intensity of the steam treatment is the highest. As a result, the total steam time (not shown) for sustainable textiles may be shorter than for normal or delicate textiles.

4 is a portion of a programmed processing cycle illustrating a drying program cycle, followed by a anti-creasing program cycle. The rotational speed of the drum and the steam flow rate are normalized as shown in FIGS. 3A-3C. Here, wet laundry discharged from the washing machine and loaded into the drum of the regeneration machine 10 is first dried. Since wet cleaning was performed by the washing machine, regeneration or dry cleaning is not required, as shown in FIGS. 3A or 5A-5B. During the drying phase, the humidity of the laundry is determined by the humidity sensor 20, and the control unit 12 adjusts the rotation speed of the drum, as well as the duration of the rotation cycle during the drying phase (program cycle). At the beginning of the drying phase, the mechanical load on the laundry is higher in order to improve the drying process. With a decrease in the humidity of the laundry, there is no need to use a high rotation speed and a longer duration of the rotation work cycles for the maximum drying process, so that the maximum rotation speed and the duration of the rotation occupancy coefficient gradually decrease as the average humidity decreases under the control of the control unit 12. The drying program cycle is completed. when the set value of the average humidity of the laundry is determined, and the control unit switches the drying program cycle to the anti-creasing program cycle .

During the anti-crease program cycle, the maximum rotation speed and the occupancy rate that was entered by the user through the rotation input panel 30 are constant and depend on the type of textile products. During the anti-creasing program cycle, steam is supplied to the drum 2, which allows the drying result to be stored in relation to the number of folds or bends on the laundry loaded in the drum.

The inventors also noted that when applying the anti-creasing program cycle, the result with respect to wrinkles formed after the drying program cycle can even be improved by reducing the number or size of creases. The average humidity of the laundry changes during the anti-creasing program cycle, the humidity increasing during the steam supply periods and decreasing between the steam supply periods. Between the steam supply periods due to actuation of the blower 16 at a low speed, weak ventilation is provided through the drum 2. FIGS. 5A and 5B illustrate the optimization of the drum rotation speed, rotation occupancy and steam supply depending on the load of the laundry into the drum 2. The rotation speed and steam flow rates are normalized as described in FIG. 3. If the weight or volume of textiles is low (low load), the maximum rotation speed and the occupancy rate of rotation are reduced, as shown in FIG. 5A. With a large weight or volume of laundry (large load of FIG. 5B), the maximum rotation speed and rotation occupancy coefficient are selected compared to the average load (not shown), where the normalized maximum rotation speed is 1, the occupancy coefficient is between the duty cycles shown in FIG. 5A and 5B and the maximum steam flow rate is also between the flow rates shown in FIGS. 5A and 5B. 5A and 5B are a preferred embodiment for supplying steam in such a way that the steam supply period lies within the periods of rotation of the drum. Thus, steam saturation of the inner space 4 of the drum 2 is prevented, which can cause condensation of the droplets.

Table 1 below shows the matrix of mechanical modes implemented by the control unit 12 depending on the type of textile products, examples of which are given in the second column of table 1. All of the listed mechanical modes relate to the regeneration program cycle, during which steam is periodically supplied to drum 2 - compare for example, FIGS. 3A-3C, FIGS. 5A and 5B. However, the mechanical mode as such (i.e., control of the movement of the drum) can also be implemented in other program cycles that do not use steam - see, for example, tables 2-4.

Table 1 Drum movement duty cycles for various types of textiles Mechanical mode (drum movement) Type of textile products (examples) Drum movement control (by duration) Forward Pause Back Pause Steam plain (cotton) Iron-optimized cotton shirts, extra long extra short extra long extra short jeans, synthetics Steam for wool Woolen Pullovers normal extra long short extra long Steam delicate (shortened or regeneration of business clothes) Woolen jackets, loose coats, cashmere, silk short normal short normal Steam for casual wear Sweaters, casual shirts long short long short

In the column "Control of the movement of the drum (duration) table 1, the periods of duration of one full cycle of movement of the drum are indicated in relative duration. The “full cycle (or period) of drum movement”, for example, is indicated in FIG. 3A by the references ON1a, OFF1a, ON1b and OFF1b. In the “Forward” column indicates the duration of rotation of the drum in the forward direction (see ON1a), which, for example, is “extra long” for the mechanical mode “Steam normal”. With reference to the “Steam Normal” mechanical mode, the “Pause” or the duration between the portion of the forward period and the portion of the reverse period is “extra short” (corresponds to OFF1a in FIG. 3A). In the “Normal steam” mechanical mode, the reverse rotation time “Reverse” (compare ON1b) is also “extra long” and is followed by an “extra short” “Pause” (stop rotation) (compare OFF1b). This means that the mechanical load on the laundry is maximized, which can be used to maximize steam supply during the steam supply phases and to maximize the drying efficiency of textiles in the drying phases.

As can be concluded on the basis of table 1, depending on the mechanical mode, the employment coefficient of rotation largely depends on the selected mechanical mode. For the mechanical mode “Normal steam”, the coefficient of employment of rotation rotation is very long (for example, the ratio of extra long / extra short is 15), while for the mechanical mode of “Steam for wool” the coefficient of employment of rotation is short (normal to extra long ratio is not more than 0.5). In addition, in the “Steam for wool” mechanical mode, the reverse rotation period (“short”) is shorter than the forward rotation period (“normal”).

As mentioned above, the “Normal steam” mechanical mode is optimized for ironing, and the mechanical load on the textiles is high, however, long periods of steam supply improve the elimination of wrinkles and bends on the processed textiles.

Table 2 shows the complete processing program for the programmatic choice of synthetics steam treatment, including the additional drying / anti-creasing program cycle (steps 2-5), the mandatory anti-creasing program cycle (steps 6-9) and the next anti-creasing program cycle (steps 10-11). The latter is designed to maintain the state of folds of linen (“folds pattern”) remaining after the previous anti-crease phase (s). As a rule, this program is used to eliminate wrinkles on previously washed (fresh or unused) linen.

In step 1, dryness / humidity determinations are performed, where the control unit 12, using the humidity sensor 20, detects wet or already dry laundry loaded in the drum 2. During the determination of humidity / dryness, ventilation through the “Ventilation” drum is carried out at a normal air flow rate or a nominal air flow rate (ON Normal). The movement of the drum (Mechanical mode) is set to “Steam Normal”, as shown in Table 1, where the rotation speed is set to the nominal or normal speed of rotation of the drum. "Steam supply" is disabled, as indicated in the last column of table 2.

At stage 1, a decision is made on the transition, if the laundry humidity is higher than the set value, the drying program cycle (step 2) and the program cycle (“Anti-crease 1” - steps 3 to 5) of the anti-crease pre-treatment are started to eliminate wrinkles due to the fact that start up when laundry is wet. If the laundry in the drum is already dry (for example, the laundry was dried after washing), the process goes from step 1 to step 6 and the program cycle (“Anti-crease 2” - steps 6 to 8) of the main processing to remove wrinkles starts.

During the drying cycle (step 2), textiles are dried to a predetermined range of residual moisture (wet or dry for the cabinet), while the ON High ventilation through drum 2 (ie, the blower speed 16) is higher than the nominal flow rate ventilation.

In steps 3 through 5, the anti-crease program cycle 1 is performed as a pre-treatment to eliminate the initial folds on the dried laundry, as opposed to the dry laundry that is loaded into the drum for anti-crease processing only. This means that the laundry loaded in the wet state into the drum and processed by the drying program cycle 2 is subjected to an enhanced anti-crease treatment. The anti-creasing program cycle includes two vapor phases in steps 3 and 5, during which the control unit turns off ventilation or sets ventilation to a reduced flow rate. During the steam supply periods (indicated by “ON” in the last column), the total volume of water is supplied as steam to the drum 2 depending on the weight / volume of the laundry. In Table 2, “Min.” Means the supply of a small amount of water (in the form of steam), “Med.” - the average amount of water, and “Max.” - the maximum amount of water.

Typically, during processing, the steam generator 24 is heated by an internal water heater to turn the water into steam, and the laundry is heated by an air heater 32 (for example, located in the channel for blowing air into the drum 2 by the blower 16). After the drying program cycle (step 2), heating the laundry is not usually required, however, when step 6 is started with cold laundry, pre-heating of the laundry may be necessary to achieve optimal steam treatment results.

Between the phases of the steam treatment (between steps 3/5, 6/8), the drying and penetration phase is activated (steps 4, 7). During these phases, on the one hand, excess moisture is removed by ventilation and, on the other hand, moisture penetrates uniformly into the laundry to equalize the moisture on the surface of the laundry and inside the laundry (internal volume of textiles).

In the column “Mechanical Mode” of table 2, the description is “Normal Steam”, corresponding to the mechanical mode “Normal Steam” from table 1. This means that the drum is moving as indicated in Table 1, where steam is supplied only at stages 3, 5 , 6 and 8, as indicated in table 2.

In the intermediate program cycle (step 9), the laundry is cooled by ventilation at a high air flow rate through the drum, and in case of drying of the circulating air, the condenser unit 18 can be turned on. This allows the user to unload the laundry after the intermediate cycle and before starting the maintenance (or safety) anti-crease phase, so that the user does not come into contact with the hot laundry. Also in step 9, condensed moisture from the reservoir of the condenser unit 18 is pumped into the reservoir of the steam supply unit 24.

Steps 10 and 11 represent a protective anti-creasing program cycle, during which the formation of new wrinkles is significantly prevented or even the wrinkle removal result achieved during program cycles 1 and 2 (steps 3 through 8) of the main processing is improved. Steps 10 and 11 can be repeated several times, for example, three times. In step 11, the laundry is dried to humidity for storage in a cabinet, or, if selected by the user, the residual moisture is maintained at a level that allows the user to iron the laundry after unloading from the regeneration machine 10.

Table 3 shows the sequence of operations for the “Refreshing Wool” treatment program, where the initial state of woolen textiles is dry, and where, as a rule, the program cycle of anti-creasing does not follow the regeneration program cycle. Stage 1 softening loaded textile products (wool) and stages 2 to 4 represent the program cycle of the main processing, namely the program cycle of regeneration. Given the tables 1 and 2, the individual elements of the array of table 3 do not require explanation, and the column "Mechanical mode" indicates that the drum moves in accordance with the mechanical mode "Steam for wool" from table 1. If necessary, the linen can be heated in step 1, when the optimization of the processing result (for stage 2) requires a minimum temperature of the linen (woolen textile).

Steps 5 and 6 represent the preparatory anti-crease program cycle used to prepare the laundry for the additional anti-crease program cycle following step 6 (not shown), in which case the user must independently start the anti-crease cycle. The anti-creasing program cycle can, for example, be started when the user does not have time to unload and hang the textiles, and thereby eliminate wrinkling by activating the anti-creasing program cycle, similar to steps 10 and 11 from table 2, for processing wool. Amount of water Min./Med. / Max. such as indicated in table 2, however, the amount is relatively calculated for the processing of wool (i.e., the Min from table 2 does not necessarily mean the same amount of water from table 3).

Table 4 presents the sequence of operations for a processing program optimized for the regeneration of "business" clothes, where the drying program cycle is not used, but where the anti-crease program cycle (steps 6 and 7) follows the regeneration program cycle (steps 2 to 4). Given the individual elements described for tables 1 and 3, table 4 is self-explanatory. A feature of Table 4 is the “Mechanical Mode” column, in which, during the program regeneration cycle (steps 2 through 4), the “Delicate Steam” mechanical mode from table 1 is used, while during the intermediate phase (step 5) and the program cycle anti-creasing (steps 6 and 7), the “Normal steam mechanical mode” from table 1 is applied. The relative amounts of water supplied to the drum in the form of steam are explained above for tables 2 and 3.
