Definitions

  • the present invention relates to a method for drying laundry and a machine for carrying out this method.
  • a tumble dryer which can be used to dry with a reduced heating power. This is provided in order to be able to dry heat-sensitive items of laundry at a reduced drying temperature. In addition, energy-saving drying is achieved in this way, whereby it must be accepted that the drying process is extended.
  • Drying with a reduced heating output only makes sense if no more than about half of the maximum permissible quantity has been filled into the dryer. If more is added, the drying time increases significantly, so that the dry goods are subjected to inadmissible mechanical stress, which can ultimately lead to wear and tear on the laundry.
  • the influence of the room temperature is related to this. If the room temperature is high, a larger amount can be dried with reduced heating power. At low room temperature, however, the laundry drying machine should be less heavily loaded.
  • Drying with only a lower heating level is inadequate, particularly for machines with a large drum content.
  • multiple heating levels or a continuous adjustment of the heating make the operation of the machine even more difficult. Success can hardly be achieved in practice, and undesirable side effects can also occur more frequently.
  • the object of the present invention is to provide a method and a machine for carrying out this method, which make it possible to carry out the drying process with an optimal effect without the operator having to have any experience in this regard.
  • this object is achieved in that the size of the amount of laundry to be dried is determined and the size of the heating power required for drying is automatically adapted to this size.
  • the stated object is also achieved by a machine, which is characterized in that a measuring device for determining the amount of the material to be dried is present, and in that a control device for controlling the heating power is connected to the output of this measuring device.
  • a laundry drying machine also called a tumbler or drum dryer, contains a perforated drum or a drum which is mounted on the end face.
  • the jacket of the tumbler surrounds the drum, a heating register, a blower and a program control device.
  • the hot air generated by the heating coil is passed through the inner drum with the aid of the fan. It dries the damp laundry while loosening it up.
  • the temperature of the air emerging from the drum can be measured at the outlet from the drum.
  • the machine is also designed so that the drying process can be slowed down in order to achieve the optimal drying effect.
  • This method of working is optional and can be used gradually, so that the possibility of drying laundry within a short period of time is also retained. Only partially switching off this possibility of slowed drying means that by changing the adaptation characteristics for extremely small filling quantities, the reduction in heating output is retained and damage to the dry goods caused by an excessively high process temperature is avoided.
  • the program control of the machine can also be used to slow down the drying process.
  • the choice of a program for synthetics can cause the adaptation characteristic to be shifted towards lower heating output.
  • the present method can proceed in such a way that, after a certain amount of laundry has been put into the machine and after starting a drying program or choosing a drying time, the machine automatically determines which amount of laundry has been added. Then, taking into account the prevailing room temperature, it chooses the economically and technically correct heating output sizes.
  • the heating output can be adjusted in several stages or continuously.
  • One of the most important problems in this process is determining the amount of laundry to be dried by the machine itself. This can be achieved, for example, by weighing the laundry. This weighing can be achieved, for example, by means of a horizontally foldable inner part of the tumble door designed as a balance.
  • the laundry can also only be weighed in the drum by, for example, one or more drum supports being designed to be resilient or provided with elements which react with a piezo effect to the load on the laundry filling. Such weighing means are generally known and therefore they do not need to be described in more detail here.
  • Another way to determine the amount of laundry in the drum is to measure the resistance of the laundry in the drum opposed to the flow of air flowing through it.
  • the heating output was adjusted right at the beginning of the drying process.
  • the heating output is only adapted to the amount of laundry loaded after a certain period of time after the start of the drying process.
  • the main advantage of this method is that at the beginning, i.e. initially dries with full heating power, which shortens the drying process, although at the same time the task mentioned in the introduction is also solved.
  • a simple method for determining the filling quantity or for assigning a specific heating output to a given filling quantity range is based.
  • a period of predetermined and constant length is selected during which the dry air flow is passed through the laundry and during which the air flow is heated with full heating power.
  • the temperature of the air flow at the drum outlet is measured.
  • the size of the heating output can either be left undiminished, or the heating output can be reduced as necessary.
  • the heating output can be reduced continuously or in stages.
  • the laundry drier which is designed to carry out such a method, can be equipped with three heating elements 1, 2, 3 (FIG. 1), each 1/3 of the total heating power. Two of these heating elements 1 and 2 can be switched off by means of thermostats 4 and 5, which are arranged in the air flow near the drum outlet. The switching temperatures of thermostats 4 and 5 are selected so that one thermostat opens its contact at a temperature that is lower than the switching temperature of the other thermostat. In parallel to the switching contacts 6, 16 of the thermostats 4 and 5, contacts 7 and 8 are connected, which are controlled by a control device 9 of the machine.
  • a program or a drying time is selected and the machine is started up. Since all contacts 6, 7, 8, 16 are initially closed, the air is first heated to full heating power. After a certain time, the contacts 7 and 8 are opened by the control device 9. Thermostats 4 and 5 were exposed to the air emerging from the drum throughout the entire period.
  • thermostats 4 and 5 Depending on the switching temperature of thermostats 4 and 5 and the amount of laundry loaded, the following switching states are now possible: If the drum has been filled completely, the temperature of the air flow at the drum outlet will have risen only slightly. As a result, none of the thermostats 4 or 5 responds.
  • the temperature of the exiting air flow will be higher.
  • one of the thermostats 4 and 5 opens its contact during the period of time mentioned which has a lower switching temperature.
  • this can be, for example, the thermostat 4, the contact 16 of which was opened during the period mentioned.
  • the time relay 9 opens the contacts 7 and 8. Since the contact 16 of the first thermostat 4 was already open, the current flow through the first heating element 1 is interrupted.
  • the control contact 8 in the second heating element 2 has also been opened by the control device, but the air at the outlet from the drum has not reached the switching temperature of the second thermostat 5, so that its contact 6 remains closed. As a result, the current flows through the second heating element 2 even after the end of the period mentioned. After this period, the air supplied to the drum is heated with a power that is 2/3 of the maximum heating power.
  • the temperature in the air stream will have reached a high value after the specified period of time, so that both thermostats 4 and 5 have opened their contacts 6 and 16 during the specified period. After the specified period of time, the air is therefore only heated at 1/3 of the maximum heating output.
  • the determination of the switching temperatures of the two thermostats 4 and 5 is expediently geared to the drum volume. An optimal adaptation can be determined very easily by tests.
  • Another option for adaptation is the choice of the number of heating levels. For machines with a small drum volume, a great effect can be achieved with just two heating levels.
  • the distribution of the heating power can also be uneven, e.g. two stages with 1/3 and 2/3 of the maximum heating output.
  • the control device can work with a relay, but it can also work electronically, in which case, for example, temperature-dependent elements be used to determine the temperature.
  • the specified time period and the signals emitted by these temperature-dependent elements can be processed with the aid of ICs or with the aid of microcomputers.
  • the adjustment characteristic can be selected according to different criteria. For example, the drying time or the specific energy consumption can be kept almost constant over the entire filling area of the machine.
  • a major advantage of the method described last is that the level of the ambient temperature of the tumble dryer is also taken into account.
  • the drying process can also be designed so that the laundry filled into the machine is first brought to a certain operating temperature by means of a fully heated air stream. The period of time required to reach the operating temperature is measured. Based on the length of the determined period of time, the size of the heating power used can then be reduced or not.
  • Such a method can in turn be carried out with the aid of a plurality of heating elements in the heating register of the tumble dryer, which can be switched off depending on the length of the period mentioned.
  • the temperature level of the drying process is higher for machines with a closed air circuit than for machines with an open air circuit.
  • the process temperatures which are dangerously high for a small filling quantity for dry goods can now be avoided without any other disadvantages.
  • the method described below is particularly advantageous for tumble dryers with a closed air circuit.
  • Most tumble dryers contain a circuit for moisture level control.
  • Such a circuit arrangement (FIG. 2) contains a scanner 10 arranged in the drum space, which is connected to an evaluation circuit 11. With the help of these parts, the electrical conductivity of the dry material is continuously monitored during the drying process.
  • a first output of the evaluation circuit 11 is connected to a humidity degree control device 12.
  • the elements of the circuit arrangement just mentioned are part of a conventional clothes dryer.
  • the time gate 13 shown in Fig. 2 is also part of a conventional clothes dryer.
  • the moisture degree control device 12 and the time gate 13 are components of the program control of the tumble dryer.
  • the circuit arrangement also contains a counter module 14, the input of which is connected to a second output of the evaluation circuit 11.
  • the circuit arrangement also contains a so-called hit logic 15 which cooperates with the counter module 14 and which is controlled from the time gate 13.
  • the hit logic 15 controls heating elements, which can be switched approximately as shown in FIG. 1.
  • the procedure just explained and with the aid of the “hit” pulses mentioned can be used to compare the number of pulses registered in the counter module 14 with a predetermined value. If the number of said pulses exceeds the specified value, the output of the heating elements is reduced to the next lower level.
  • the Sampler 10 used as usual for humidity control.
