Definitions
- the invention relates to a method for determining the properties of items of laundry in a drying process and to a condensation dryer suitable for carrying out this method (also referred to below as "dryer”.)
- the invention relates in particular to a method for operating a condensation dryer with a process air channel, a drum
- the invention also relates to a condensation dryer which is particularly suitable for carrying out this process.
- Drying processes according to the condensation method are based on the evaporation of moisture from laundry items by means of warm process air and dehumidification of the process air by condensation on a heat exchanger.
- the cool process air is initially passed through a fan generally via a heater.
- the dry-heat process air then enters the drum as a drying chamber, which contains the items to be dried.
- the dry-heat process air absorbs moisture from the laundry.
- the now moist, warm process air is forwarded from the drum to the dehumidification, for example, in an air-to-air heat exchanger or the evaporator of a heat pump.
- the moist, warm process air is cooled down therein and the water contained in it is condensed and collected in a so-called condensate tray, which is generally located below the heat exchanger.
- the condensed water is typically pumped by a pump (also referred to herein as a "condensate pump") into an intermediate storage tank (referred to herein as a “condensate tank”) or into a sewer.
- a drying process is divided into three phases, namely a heating phase, a main drying phase and a cooling phase.
- the heating phase the process air temperature rises until a predetermined temperature value is reached.
- the process air can progressively more water out of the Take up laundry, ie it condenses increasingly more water to the heat exchanger used for cooling.
- the preset temperature the process air generally absorbs a constant amount of water from the laundry in the drum. This means that the condensation of water remains constant.
- This section is referred to as a stationary phase of a drying process or as a main drying phase. The course of the evaporation or condensation is stationary as long as surface water evaporates from the laundry items.
- a drying process (also referred to as a "drying program") is concluded with a cooling phase in which the heating is generally switched off and in which the dried laundry is cooled.
- the transition from stationary to unsteady phase is of particular importance, since this transition contains information about the moisture content of the items of laundry and thus makes it possible to control a drying process very precisely and thus to carry out laundry-friendly and energy-efficient.
- a method that enables accurate determination of this transition in a drying process is therefore desirable.
- the heating-up phase is also important for a laundry-friendly and energy-efficient control of a drying process.
- a determination of the loading of the drum with items of laundry should take place as early as possible in a drying process in order to be able to adapt the drying process to the loading at an early stage, since different quantities of items of laundry behave differently.
- a method which allows a determination of the load already in the heating phase is therefore desirable.

- the amount dependent on the fabric moisture is used in conjunction with the measure of the temperature of the air stream before and / or after its contact with the laundry to estimate the loading and / or the drying time.
- EP 2 227 585 B1 describes a laundry drying apparatus and a method for operating this apparatus, in which a moisture content of process air discharged from a laundry drum is determined and the moisture is at least partially condensed with a heat exchanger from the process air, wherein the moisture determination by measuring at least one Temperature for a medium flowing through the heat exchanger and by evaluating the measured temperature is determined.
- the medium is either the process air or a coolant, and the moisture content is determined by measuring an outlet temperature of the medium on the outlet side of the heat exchanger and measuring an inlet temperature of the medium on the inlet side of the heat exchanger.
- the disadvantage is that the laundry drying device must additionally be configured with at least one temperature sensor.
- WO 2014/040904 A2 describes a condensation dryer with determination of the load and a method for its operation.
- At least one temperature sensor is arranged in a cooling medium channel and / or process air channel and the control device is set up in order to determine a loading of the drum with items of laundry on the basis of a time profile of the temperature measured with the at least one temperature sensor and a time profile of the amount of condensed water.

The heating of the air flow is interrupted in response to the variation (Q) which decreases below a predetermined value during at least one of the time intervals (tx).
- the object of the present invention was to provide an improved method for determining laundry properties and for controlling a drying process in a condensation dryer.
- the object of the invention was also to provide a suitable condensation dryer.
- the amount of condensate set i m is generally determined as the in the drain pan to a predetermined level trapped amount of condensate. This level may be determined by a level sensor or level-dependent switch which, upon reaching this level, switches a condensate pump through the water collected in the condensate tray, which then pumps the accumulated water.
- the beginning of the process according to the invention generally takes place at the same time as the initiation of a drying program. In this generally a heater and a blower are turned on to direct heated process air for drying wet laundry in the drum.
- the properties of laundry articles herein preferably include a degree of moisture and a loading amount.
- the degree of moisture of the laundry changes during a drying process, since first evaporates surface water and finally pore and capillary water from the fabric of the laundry.
- the course of a degree of moisture in a drying process is different and a continuous and accurate determination of a degree of moisture therefore advantageous for a laundry safe and energy-efficient drying of the laundry, as well as a precise control of the residual moisture a predetermined value such as "iron dry".
- the properties of laundry items include, for example, a loading amount.
- a determined loading amount refers to the dry mass of the laundry items to be dried introduced into the drum.
- items of laundry have a moisture content, based on the dry weight of the items of laundry, for example of about 60% after a washing process and spinning at 1200 rpm.
- different loading volumes behave differently in a drying process. This is how it can be for example, prolonging a full-load drying process versus a half-load drying process.
- the duration of the individual phases passed through in the drying process can be different.
- properties of items of laundry are determined by a relationship stored in a control device for different values of a period At n with n> 1.
- the time period At n is the period of time required for the condensation of an amount m set i of water from moist, warm process air, whereby the time period At n can be measured by evaluating a pumping cycle of a condensate pump which stores the condensate collected in the condensate tray for temporary storage. or pumped out for disposal.
- a pumping cycle comprises at least one operating phase and a rest phase of the pump, wherein an operating phase is characterized by the pumping of condensate and a rest phase by a standstill or a state of low operating power without delivery.
- the length of a rest pause of a condensate pump is used as a measure for the period At n .
- the operating phase of the pump is generally initiated when at least one liquid sensor located in the condensate tray responds.
- an operating phase of the condensate pump is initiated when a predetermined maximum water level H max1 is reached in the condensate tray , and the operating phase takes so long until the predetermined amount m set i is pumped out of water and thus a minimum water level H min is reached.
- the length of a rest pause of a flow sensor in a condensate channel is used as a measure of At n in addition or alternatively to the evaluation of the rest period of a condensate pump.
- the type of flow sensor is not limited. In general, a flow sensor measures a volume flow of aqueous liquid per unit time.
- the flow sensor responds and sends a sensor signal to the controller as condensate flows past the condensate channel past the flow sensor. This is the case when the operating state of the pump is initiated. If the pump goes into rest, so no condensate flows through the condensate channel and past the flow sensor and the sensor sends no more sensor signal to the control device.
- the sensor signal of the flow sensor can thus be measured alternatively or additionally by the time measuring device and from this a time period At n can be determined.
- the term "liquid sensor” means a sensor or sensor system that can detect the presence of aqueous liquid
- response as used herein means that a sensor signal from the sensor indicates the presence of an aqueous liquid.
- the liquid sensor is generally a water level sensor or a system of water level sensors. According to the type of water level sensor is not limited.
- the water level sensor may be, for example, a sensor with reed contact and float, an optical sensor or a conductivity sensor. Different types of sensors can be combined with each other.
- a conductivity sensor in the height H max1 is arranged in the condensate tray .
- the condensate accumulating on the heat exchanger during the drying process is collected and collected in the condensate tray. If the level of the condensate reaches the height H max1 , in which the conductivity sensor is arranged, it responds. Via a control device, the sensor signal is evaluated and initiated an operating phase of the pump.
- the pump then generally transfers the condensate from the condensate tray through a so-called condensate channel to a caching container, also termed "condensate container", or for disposal in a sewer Level H min , so the pump goes into the rest phase, until the level H max1 is reached again by the incoming condensate
- the rest phase of the pump can be initiated for example by means of a second water level sensor at the height H min or by another
- a third conductivity sensor is additionally arranged at a height H max2 which is lower than the height Hmax-i, the conductivity sensor being activated at H max2 independently of the conductivity sensor at H max1 by a control device w the term "activated" means Here, the sensor responds in the presence of aqueous fluid.
- m set i and m set 2 of condensate for initiating the operating phase of the pump can be specified by the two different filling levels H max1 and H max2 .
- a relationship is established between a time interval At n measured with the time measuring device for the condensation of an amount m set of water from moist-warm process air and the properties of the laundry items in the drum.
- a quotient Q is formed from a measured time period At n and a following measured time period ⁇ ⁇ + ⁇ :
- the quotient Q ⁇ 1 since in this phase, the production of condensate is not constant and increases with time.
- the process air which is generally passed through the laundry items by means of a blower has not yet reached the prescribed process temperature. Therefore, the amount of water, which is absorbed by the dry-heat process air in the drum with laundry items. Thus, the amount of water that condenses in the heat exchanger from the moist, warm process air also increases.
- a predetermined in the condensate tray level, for example, H max1 , and a corresponding predetermined amount of condensate, for example m set1 is reached faster and the operating state of the pump initiated faster.
- the measured period At n shortens, At n > At n + i.
- a first phase of the main drying phase the quotient Q is equal to 1.
- This phase is referred to as a stationary phase, since the condensate production is constant here under constant conditions.
- surface water evaporates from the laundry in the drum.
- a predetermined level in the condensate pan example wise H max1
- a corresponding predetermined amount of condensate for example m se ti, each reached the same speed and initiated the operating state of the pump in constant cycles.
- the measured period At n is also constant, it holds
- This phase is called the transient phase.
- condensate production decreases over time.
- a predetermined in the condensate tray level, for example, H max1 , and a corresponding predetermined amount of condensate, for example m set i, is increasingly reached later and the operating state of the pump initiated later.
- the measured period At n becomes larger, so that At n ⁇ At n + 1 holds.
- the predetermined amount m for the condensation of water is reduced to a value m set 2 ⁇ m set i.
- the number of pump cycles and thus the number of measurement values for At n increases , which increases the accuracy of the measurement in the transient phase. This is advantageous since, in particular toward the end of the drying process, the degree of moisture of the items of laundry is close to the predetermined residual moisture level and accurate determination of the degree of moisture permits a targeted termination of the drying process.
- the method is carried out until Q has reached a predetermined value Q set i as a measure of a residual moisture content of the items of laundry, whereby a relationship between Q and the residual moisture of the items deposited in the controller is used to determine the residual moisture.
- a predetermined value Q set 2 for Q a power of the heater is lowered or the heater is even turned off. In this way, the method according to the invention can be made even more energy-efficient and even more laundry-friendly.
- the first time period At-i is evaluated as a measure of the loading of the drum with items of laundry, wherein for evaluation purposes, a relationship stored between the At-i and the loading of the drum with items of laundry is used in the control unit.
- this also a kind of laundry and thus the fibers are taken into account.
- loading means the dry mass of the laundry items to be dried introduced into the drum.
- the initiation of the first pumping cycle is delayed in time as the loading of the laundry drum becomes smaller. For example, garments having 1200 rpm. were spun in a washing machine, a residual moisture of 60% water.
- a first water level sensor in the height H max1 and a second water level sensor in the height H min are arranged as a liquid sensor in the condensate tray such that a level difference between the first and second water level sensor corresponds to a quantity mi of condensate.
- a third water level sensor in the height H max2 is arranged, wherein a level difference between see second and third water level sensor corresponds to an amount m 2 ⁇ mi of condensate.
- a condensate pump is arranged in the condensate tray or in a condensate tray connected to the condensate tray.
- a flow sensor is arranged in a condensate channel connected to the condensate tray.
- the condensate tray is generally connected via a so-called condensate channel with a container for intermediate storage of the condensate, ie a condensate tank, or with a sewer pipe for disposal of the condensate. Since the condensate tray is usually arranged in the bottom group of the condensation dryer and the condensate is removed from it against gravity, a condensate pump is generally arranged in the condensation dryer according to the invention in the condensate tray or in the condensate channel.
- the condensation dryer according to the invention furthermore generally has a heater, in particular an electric heater or a gas heater, wherein an electric heater is preferably used. The heater serves to heat the process air before it is introduced into the drum of the condensation dryer.
- the condensation dryer according to the invention generally also has a temperature sensor, which is arranged to measure the process air temperature in a process air duct or a cooling air duct.
- the condensation dryer For conveying the process air, the condensation dryer also generally has a fan in the process air duct.
- the condensation dryer according to the invention which can be designed as an exhaust air or circulating air dryer, at least one heat exchanger for dehumidifying the moist, warm process air is present. This is generally achieved by cooling the moist, warm process air.

- the heat exchanger is in particular an air-air heat exchanger or a heat sink of a heat pump, in particular an evaporator.
- a heat pump is characterized by two heat exchangers, namely a heat sink, in which heat is absorbed, a heat source in which heat is released, and a pumping device, which transfers heat from the heat sink to the heat source optionally with a change in temperature.
- the cooling of the warm, moisture-laden process air takes place essentially in the heat sink of the heat pump, also referred to as evaporator, where the heat transferred is used to evaporate a refrigerant circulating in the pump device designed as a circuit ,
- the refrigerant evaporated due to the heating is supplied to the heat pump in the pump device via a compressor of the heat source, which is a condenser for the refrigerant, where due to the Liquefaction of the gaseous refrigerant heat is released.
- a compressor of the heat source which is a condenser for the refrigerant, where due to the Liquefaction of the gaseous refrigerant heat is released.
- the then liquid refrigerant is expanded in a throttle of the pumping device, whereby its internal pressure is reduced, and finally passes back to the evaporator.
- the condensation dryer according to the invention is located in the process air duct preferably an air-to-air heat exchanger or an evaporator of a heat pump. If an air-air heat exchanger is used, preferably a cooling air duct is present therein, through which comparatively cool air, in particular from an installation space of the dryer, is passed as the cooling medium by means of a cooling air blower.

- a condensation dryer 1 shows, in particular, a vertical section through a condensation dryer 1 according to a first embodiment, which has, as a heat exchanger 15 for dehumidifying the process air, the evaporator 15 of a heat pump 12, 13, 14, 15 and a drum 3 rotatable about a horizontal axis as a drying chamber, within which drivers 21 are mounted for movement of laundry during a drum rotation.
- the arrowheads with filled tip indicate the flow direction of the process air.
- process air duct 2 closed in this first embodiment process air is conducted via an electric heater 4 with the aid of a process air blower 6. The process air heated in this case then passes into the drum 3, where moisture is removed from the moist laundry items not shown in FIG.
- the process air heated by the electric heater 4 is directed from the rear, ie from the side of the drum 3 opposite a dryer door 22, through the perforated bottom into the drum 3.
- the moist, warm process air leaves the drum 3 via a lattice grate 31 and flows in the process air duct 2 to the evaporator 15 of the heat pump.
- a circulating in the heat pump circuit 12, 13, 14, 15 refrigerant is evaporated due to the heat exchange with the moist, warm process air and fed via a compressor 13 to a condenser 12.
- the moist, warm process air is thereby cooled in the evaporator 15 of the heat pump 12, 13, 14, 15 and the vaporized refrigerant of the heat pump via a compressor 13 to the condenser 12, where the refrigerant cooled with heat to the flowing in the process air duct 2 cooled and dehumidified process air liquefied.
- the liquid then present in liquid form is passed via a throttle valve 14 in turn to the evaporator 15, whereby the refrigerant circuit is closed.
- the arrowheads with the tip not filled indicate the flow direction of a refrigerant in the heat pump.
- a condensate tray 17 is mounted below the evaporator 15, which catches the water condensing in the evaporator 15 from the moist, warm process air. With the help of a condensate pump 20 in a condensate channel 18, the collected condensate is pumped into a condensate tank 19.
- a liquid sensor 1 1 which is here a system of at least two water level sensors otherwise not shown in detail, for which purpose conductivity sensors are used. In particular, a conductivity sensor should be located at a height H max1 .
- the condensate pump 20 is triggered when the liquid sensor 1 1 responds upon reaching the level height H max1 .
- the condensate pump 20 can be controlled so that it interrupts their operation falls below a predetermined minimum level H min .
- the period of a pumping cycle At n can be determined, according to the invention, the length of a rest pause of the condensate pump 20 is used as a measure of At n .
- the response and silence of the flow sensor 32 in the condensate channel 18 can be used to determine the period At n , in particular a rest period of the flow sensor 32, which generally corresponds to a rest period of the condensate pump 20.
- the drum 3 is mounted in the embodiment shown in Figure 1 at the rear bottom by means of a pivot bearing and front by means of a bearing plate 7, wherein the drum 3 rests with a brim on a sliding strip 8 on the bearing plate 7 and is held at the front end.
- the control of the dryer via a control device 10, which can be controlled by the user via an operating unit 9.
- a display device 33 allows the display of a residual maturity of the drying process with respect to a user selected residual moisture value, such as ironing dry, or the display of the determined load or other conditions of the dryer or the display of the status of the drying process, for example in color differentiated form.
- the dryer for determining the residual moisture of the laundry items and the load on the controller 10, the liquid sensor 1 1, the condensate pump 20 and the flow sensor 32 in the condensate channel 18 and a time measuring device 5.
- the conductivity sensor 1 1 sends a signal to the control device 10, which triggers an operating phase of the condensate pump 20.
- the condensate pump 20 pumps the condensate from the condensate pan 17 via the condensate line 18 into the condensate tank 19.
- the condensate pump 20 interrupts its operation.
- the time measuring device 5 starts timing in the present first embodiment when a drying program is started.
- the loading of the drum 3 with laundry items can be determined, for evaluation, a stored in the controller 10 relationship between At-i and the loading of the drum 3 is used with laundry ,
- the time measurement by means of the time measuring device 5 can in principle be continuous or discontinuous, but in the present case at least one rest period of the condensate pump 20 or the flow sensor 32 is evaluated.
- a time measurement takes place exclusively during one or more rest periods.
- the predetermined amount m for the condensation of water is reduced to a value m set 2 ⁇ m set i. This achieves a relative reduction in the length of the rest periods of the condensate pump 20 and achieves an improved accuracy of the method overall by way of a relative increase in the number of evaluable rest pauses.
- the method according to the invention is carried out until Q has reached a value Q set i directly or indirectly predetermined by a user as a measure of a residual moisture content of the items of laundry, wherein a relationship stored in the control unit 10 determines the residual moisture between Q and the residual moisture of the laundry is used.
- a power of the heater 4 can advantageously be reduced when a predetermined value Q set 2 is reached for Q.
- FIG. 2 shows in a section a vertical section through the condensate tray 17 of a second embodiment of a condensation dryer, which is not shown in detail.
- three conductivity sensors 1 1 1 a, 1 1 b and 1 1 c are arranged in the condensate pan 17 in the level heights H max1 , H min and H max2 , where H max1 > H max2 > H min .
- the conductivity sensors 1 1 a and 1 1 c can be activated or deactivated independently of each other via the control device 10. In this way, two different quantities m set i and m set 2 can be specified for condensate with m set i> m set 2.
- the operating phase of the condensate pump 20 is already initiated at a lower level of condensate. This increases the number of pump cycles and more values for At n can be measured, thereby increasing the moisture level the items of laundry can be more accurately determined via the stored in the control device 10 context.
- 18 here means a condensate channel for the discharge of condensate in the direction of arrow to a sewer or a condensate tank for temporary storage.
- the arrowhead shows in particular the flow direction of the condensate during a pumping operation.
- 1 1 c third water level sensor be: ' I ma x2
