Abstract

The disadvantage of known washing/drying machines, that, after the wash, the laundry cannot be dried in the same drum in one operation, is overcome by the apparatus according to the invention, since, in this apparatus, the heat radiators (28) radiate their heat rays (S) directly into the entire drum interior, the heat radiation being assisted by hot air blown into the drum by means of a blower. Heat radiation, convection and heat conduction bring about a rapid drying of the entire laundry batch. For drying purposes, the moist air can be guided via a cooling surface (78), which can be the limiting surface of an evaporator (37) of a refrigerator, and be sucked up by the said blower via the funnel (111) and used again for drying. During the washing process, the washing fluid is conveyed in circulation through the interior of the drum (5) via a funnel (32) by means of a pump (63), and the heat radiators (28) simultaneously radiate into the drum interior. In the same way as the drying process, the washing process is also accelerated as a result of the interaction of heat radiation, convection and heat conduction. <IMAGE>

Description

Device for washing and optional drying

of laundry or (like.

The invention relates to an arrangement for table and optional drying of laundry o (i.d $ # l.

In known devices of this type is used for heating the washing liquid or a heating unit is used for preheating the dry air, which is located outside The drum is, however, especially during the drying process, in disadvantageously shielded the heat radiation through the drum walls, whereby the drying process is delayed because only the heat conduction and the convection are used, but not the thermal radiation that is used for transmission the warmth from one body to another not the cooperation of those in between Matter needs, because the carrier of the thermal energy in the thermal radiation is electromagnetic Due to the arrangement of the heating units outside the drum, shafts are known Devices are heated in addition to the drum, other parts of the machine, causing excessive heat loss.

As a rule, in known devices, in which one and the same Drum in one and the same machine, both as a washing and drying drum serves, the filling maximum for the drying process is much smaller than the filling maximum for the washing process, i.e. after washing or spinning the laundry, if the maximum capacity is to be used for the washing process, not for drying all of the material remains in the drum, but part of it has to come out of the drum be taken out, which of course the continuity of the work process and the Reduced convenience of these devices. This time-consuming capacity reduction is a consequence of the more or less concentrated wet laundry or at all the ineffective heat transfer in the deeper fabric layers of the textiles by means of heat conduction and convection.

It is the object of the invention to remedy these disadvantages of the known ones Avoid devices and use a device of the type specified in the introduction to train that the washing and drying of the laundry or the like. in one and the same Drum can be carried out, advantageously the heat directly is blasted into the drum in which the laundry is located. Through this especially when infrared radiation of a suitable wavelength, be it that it is generated by light or dark radiators, is used, both the washing process as well as the drying process are shortened because the infrared radiation has an excellent depth effect. This depth effect of the infrared radiation causes on the one hand that the soiling of the inner tissue layers during the washing process dissolve more quickly and are thus better washed out by means of the washing liquid and on the other hand that the drying process accelerates the moisture from the can diffuse deeper tissue layers, which is a gentle treatment of the Fiber is important.

The previous emphasis on the use of heat radiation but should the application of the other two heat transfer options, namely those of thermal conduction and those of convection, do not exclude. In particular is successful and economical washing and drying without simultaneous Use of convection not as possible The simultaneous use of thermal radiation uer convection should work in an optimal way when washing and especially when Add drying. For this purpose, on the one hand, when washing the washing liquid existing liquid heat transfer medium and, on the other hand, also the gaseous ones during drying Heat transfer media, which will usually consist of air, pass the arm radiators are fed into the drum, with the higher thermal energy that the heat carriers when passing the radiant heater was issued to the textiles that are in the Drum are to be cared for, comes into effect, be this now that through the heated washing liquid in cooperation with the rotation of the drum of the washing = effect or be it, dad during the drying process through the heat transfer medium of the Water vapor that accelerates from the deeper tissue layers through heat radiation diffused, transported away. ble with water enriched air should after Leaving the drum on a cooling surface can be passed, with at least some of the water carried in the air condenses. this cooling surface can be artificially cooled. However, artificial cooling should not be mandatory but it should also be possible within the scope of the invention, since this Kühlflä.che only one wall of the representational, usually cuboid, device which is of such a nature that it takes the poor away well.

These tasks are identified according to the invention. solved by that one or more heat radiators as well as conveying and / or guiding devices in such a way can be brought into the area of one or more openings of a drum or attached there or can be introduced into or into an opening that the heat rays as well as optionally liquid or gaseous heat exchangers by means of the conveying and / or Loiteinrichtunt: en can be directed into the interior of a drum and optionally never gaseous rirm = carrier after passing through a drum over a known cooling surface can be removed or recycled.

This construction enables washing and drying in one place Device to run with a single drum without usually after ash or

laundry must be taken out of the drum before drying, rather, it is usually continuous care, starting with washing up to ironable drying, be possible.

A prerequisite for the items to be washed optimally in these processes is of course a programmed control of the entire process. Such program controls are, however, in washing machines and tumble dryers or well known for combined devices and are not the subject of this Invention. It should only be pointed out that the radiant heaters can be regulated should be or that, as the process progresses, emitters depending on the energy requirements can be switched on or off. The maximum output should be achieved during the warm-up period the heater (s) are used, while towards the end of the drying process, when the heat of evaporation is no longer required, the radiant power is reduced otherwise the temperature of the textiles will rise rapidly what should be avoided for quality-preserving reasons. Facilities, which automatically make such a temperature control are known and not the subject of this invention, for this reason also on the graphic Representation of these already known facilities is dispensed with, as is the case already known mechanical devices in washing machines and tumble dryers, such as for example on the bearing and the drive of the drum, on the pump arrangement, on the most diverse sealing options, as well as on electrical safety switches etc. will not be discussed in more detail if this does not enrich the invention.

The devices are then closed, with a view to this make sure that the ventilation flaps or

the ventilation slide, which in some embodiments of the invention Device are attached to the loading doors 1, closed before commissioning if this does not happen automatically, so that during the washing process, the Washing liquid through the ventilation openings 6, which during the drying process for the air passage are provided, can escape.

For example, in the device according to FIG. 8, the door-shaped one Ventilation flap 7 and in the device according to FIGS. 1o and 12 are louvre-like To close wings 8 manually, for example by means of a cable pull.

The ventilation openings 6 in Fig. 12 can also be through the wings 8 by means of an activated rod-shaped electromagnet 9 (Figure 4), which the Wings 8 tightened against a spring 10, are closed, the timely Switching the electromagnet 9 on and off expediently via a program circuit he follows. Of course, the ventilation openings 6 can be closed by the wings 8 can also be made by another adjusting device.

The ventilation openings 6 in the loading door 1 according to a device 13 are by a slide 11, which by means of the handle 12 in a Guide 13-13 is vertically displaceable, closed by the slide 11 by means of of the handle 12 is lifted to the upper stop of the guide 13 'to then against the loading door 1 to be pressed with an or a plurality of solenoids 14 which can be switched on by pressing the slide 11, the at the contact surface with the electromagnet with a ferromagnetic insert 15 is provided, pull on loading door 1. Seals 16 take care of a good closure. Before the start of the drying process, a program can be switched cause the switching off of the electromagnet 14, whereby the # slide 11 through the force of gravity falls back into the position shown and with the ventilation of the items to be washed can be started.

Known safety switches should ensure that when the Loading doors or ventilation flaps or ventilation slides of the washing process cannot be initiated.

In a known manner, the electricity and water supply is enabled and The individual process steps are then used in a known program control of washing and drying transferred.

First, water is poured into a collecting container 17 (Fig. 2, 14 and 15) of known design and this is in a known manner by adding a detergent prepared for washing liquid, with which the laundry, the is located in the drum, for example is flooded via holes 18, wherein the viaschiquid on the one hand under the action of heat generated by a heating unit, which is located in a known manner outside the washing drum and / or according to the invention of radiant heaters, which the heat partly by radiation and partly by means of Bring convection directly into the drum, is released, and wander under mechanical action caused by rotating the drum in a known manner is used to wash the items to be washed.

This turning of the ro: rm'el succeed @@ @n. known way by a Motor, he draws @@@ is not shown and the transmission facilities he ~ C-i motor produced rotary movements on the drum should be of any suitable Nature, as should also be the case for the storage of the drum these numerous possibilities are outside the scope of the invention.

Nevertheless, seller. Storage and drive options the drum shown earth.

For example, the drum 4 according to the embodiment is in FIG Fig. 1 shows a shaft 19 which carries a drive pulley 20 in a bearing block 21 mounted on the rear housing wall 22 of the device.

In the Äusüührunsform zems: Figs. 8 and 9 takes place, for example the drive of the drum 4 by a gear 23, which is of a not shown rotor is driven and that with the toothed wheel 24, which is located on the drum approach 25 is located, is engaged. The wheel 24 can also be used as a V-belt pulley be designed so that the drum 4 by a V-belt set with a Motor (not shown) is connected, can be driven.

Furthermore, the drum 5 is, for example, according to the embodiment 14 by means of a hollow shaft 26 designed as a V-belt pulley in the bearing block 27, which is fixedly anchored by supports that are not visible in the section shown is stored and is driven by a motor, not shown, via V-belts.

The drive of the drum 5 in FIG. 15 can be via one of the two disks 20 and 26 respectively. For example, the drum 5 can over the disk 26 in a slow rotary motion and a rapid (e.g. when spinning) rotary motion via the disk 20 be moved.

There is a preferred embodiment of the device according to the invention in that the heat radiator (s) 28 on a carrier 29, which in the embodiments 14 and 15 fixedly connected to the device according to the invention is, while it is grown on the loading doors 1 in the other embodiments is, are attached so that the Strahlunsfiäne the heat radiator 28 through a circular drum opening 3o on one of the two end faces of a drum 4 or 5 is directed directly into the interior of the drum, both when washing as even when drying the items to be washed, this is done both by thermal radiation and by Convection, in which, on the one hand, the liquid heat carriers exist during \ #ashing from the washing liquid, and on the other hand the gaseous heat transfer medium during drying, consisting of air, past the heating surfaces of the heat radiator 28 and so the items to be washed are brought to the evaned temperature more quickly.

The heat radiators 28 can be of various types.

It can be both bright radiators and radiators that are predominantly at high temperatures in the range of visible light (approx. 0.4 to 0.75 micrometers) emit, as well as dark radiators, which have their emission maximum at less high temperatures have, act in the long-wave infrared - i.e. in the invisible range. So For example, the bulb-shaped heat radiator 28 in FIG. 8 can be used as the Representative of a bright radiator can be viewed, while the heat radiator 28 in the other figures of the drawings taken as representatives of dark radiators can be. Of course, a combined use of light and dark = radiating take place, as shown for example in Fig. 8, in which, as already stated, a bright radiator is represented by 28, while 28 'represents a dark radiator.

As can be seen from FIGS. 1 and 2 or 5 and 6, the Heat radiator 28 can either be designed in the form of a plate with openings 31 or the, Zärmestrahler 28 each consist of a group of individual emitters, which are arranged at intervals, which are again indicated by 31, from one another are. The heat radiator according to FIG. 15 consists of a group of rod-shaped or cylinder = shaped individual radiators. The heat radiators 28 in FIGS. 1o and 12 are ring-shaped, as is the heat radiator 28 'in FIG. 8.

As can be seen in FIGS. 10 and 12, several such rings arranged one behind the other generally form the noise radiator 28. In the execution forms 13 and 14 are conical tubular or funnel-shaped heat radiators 28, which is caused by the inclined radiation surface that is created by that the diameter of the drum 4 (Fig. 13) or 5 (Fig. 14) facing tube end is larger than that of the tube end facing away from the drum, cause the interior the drum is emitted particularly well because of the cone-shaped radiation also those areas in the drum 4 or 5 are detected, which in the case of cylindrical Radiation could not be recorded as well as from the course of the perpendicular Edge = rays S emitted to the radiation surface can be seen. Since the Open carrier 29 in a funnel shape in the direction of the drum axis and thus create a funnel 32 form, the funnel walls are designed as reflectors 33, the Drums 4 through the heat = radiators 28 and 28 'in the embodiments according to FIGS. 8 to 12 and 15 are broadcast well. The heat radiators 28 can at their rear side facing away from the drum opening 30 in addition to thermal insulation 34 of the carrier 29 can be insulated. The reflectors 33 not only guide those rays which impinge on them directly from a heat radiator 28 through a drum opening 30 into the interior of a drum 4 or 5, but also those rays are emitted from them, which are reflected from a drum wall into a funnel 32 of a carrier 29, thrown back into the drum.

The reflector 33 'in the embodiment according to FIGS. 1 and 2 has to fulfill a double function. On the one hand, it has to perform a reflector function, 5by throwing back the rays that strike him from the heat radiator 28, that is to say has to reflect into the interior of the drum 4, and for this reason the side facing the drum 4 is reflective, while that of the Drum 4 facing away from the side is thermally insulated, so that the heat loss to the outside is kept as low as possible and, on the other hand, the plate-shaped reflector 33 ' to fulfill the function of a partition, namely at the beginning of the washing process, as soon as the ash liquid rises in the collecting tank 17, in a guide 35, which runs on the one hand in the housing 22 and on the other hand in the loading door 1 and when loading door 1 is closed, an unobstructed passage is guaranteed, between the .Zärmestrahler 28 and the fan or blower 36 pushes because the Reflector 33 'is attached to a float 37' and thus the movement of the liquid keitsstandes in the collecting container 17 follows. The up and down movement of the reflector 33 'can also by means of a lever arrangement which is located between the float 37' and the Reflector 33 'is attached, take place. The reflector designed as a partition 33 'thus prevents the washing liquid from escaping through the ventilation openings 6 on the loading door 1 of an embodiment according to FIG. 1. Before the drying process the washing liquid is pumped out of the collecting container 17 in a known manner, whereby the reflector 33 'slides back into the position shown in FIG.

As a result, during the drying process, the fan resp. Air sucked in by the fan 36 (FIG. 1) via the ventilation openings 6 via the heat radiators 28 are conveyed into the drum 4.

However, before the drying process is dealt with in general, in the consequence of the heating of the washing liquid and the circulation of the same by means of conveyors during the washing process in the case of the invention Devices received.

As stated earlier, the washing liquid is carried through the heat radiator 28 brought to the desired temperature, the washing liquid in addition to the warming it experiences from the thermal radiation, also through more or less intensive d ten contact with the la-mesa emitters 28 can be heated.

This direct contact of the washing liquid with the heat = radiators 28 comes in the embodiment according to the invention according to FIGS. 1 and 2, 8 iind 9 and 13 very loosely, that does not help very much, because it is conditional by the rotary movement of the drum 4, eie with washing liquid flooded with it When the laundry is filled, a small amount of the total washing liquid is added when the leather is turned through the openings oes arranged on the carrier 29 en # eoroneten protective grille 37 on the heat radiator 28 e is promoted, the temperature of these contactors Amount of washing liquid and thus that of the total washing liquid increased, because yes the contacting washing liquid immediately after contact with the heat transfer units 28 Us the funnel 32 flows back into the drum 4 and there with the remaining washing liquid mixed, whereby a temperature equalization is explained.

@ei Elner other Ausfürungsform the device according to the invention before 5 and 6, the washing liquid is by means of a pump in the drawing is not shown, via a guide device 38 on the carrier 29 is arranged, sprayed through the funnel 32 into a drum 4, from where it passes through the perforations in the drum reaches a collecting container in order to be removed from the Pump to be sucked again, with the washing liquid every time it passes the radiant heater 28 absorbs heat. The washing liquid can, however, by means of the Pump also through the connection opening 39 (Fig. 6) in the funnel 32 and over the Heat transfer device 28 are conveyed into the drum, for example, via the guide device 38 air is to be introduced during the drying process. Optionally, you can also use the Leitein = direction 38 washing liquid during the washing process and via the connection opening 39 Air during the drying process be conveyed into the funnel 32. But it can also use a single device 38 or 39 both the washing liquid introduced into the funnel 32 during the washing process as well as the air during the drying process if one of the two devices has both a connection P to a pump for the washing liquid as well as a connection G for a tuft conveyor system, e.g. a fan. The connecting lines between the devices 38 and / or 39 on the one hand and the conveyor facilities on the other hand, which can lead to the devices 38 and / or 39, both with 38 'and with 39 ', while the connection side that leads to the pump, with P and those that to the fan or the like.

leads, is denoted by G, with which all possible connections are recorded. Dz in an embodiment according to FIGS. 5 and 6, the conveying devices not arranged on the carrier 29, which in turn is attached to the loading door 1 are, but the conveyors outside of the carrier 29 at suitable Places of the device according to the invention are located, it is in connection with it, that yes the loading door 1 via hinges 40 fastened to the housing wall 22 must be able to be opened and closed, it is necessary that either the connecting lines flexible or, if the design is rigid, it can be interrupted or coupled have to. For example, the connecting lines 38 ', 3 °' - P and 38 ', 39'- G is formed like a hose between the joints 40 in FIG. 6 and can thus follow the movements of loading door 1. Through openings 4. in the housing wall 22 these connecting hoses lead to the associated conveying devices.

In Fig. 7 the device is a rigid connection = line 38 ', 39'-P or 38', 39'-G shown, which at the same time = as locking the Loading door 1 is formed.

When opening the loading door 1, the slide 42 is manually in Direction of arrow 43 against the force of a compression spring 44, which wipe the pipe pieces 45 and 38 ', 39' - surrounded by a protective sleeve - is arranged, shifted, being the tube end 45 from the annular sealing groove 47 of the Pipe P, G in the housing wall 22 of a device according to the invention = out and the loading door 1 is to be opened. In Fig. 7 is the locked State of the device shown, whereby the coupling of the pipes 45 - P, G the flow channel represented by arrow 48 is closed.

The arrow 48 is also the direction of flow for the washing liquid or indicated for the air. as soon as the device according to the invention is in operation is taken what in a known manner by an appropriate safety switch is only possible when loading door 1 is closed, a program switch can be made effect that the slide 42 is fixed by an anchor 49. it is more purposeful if you have both washing liquid and air via a rigid connection line Ver according to Fir. 7 to the devices 38 and / or 39 wants to bring and one of additional Would like to foresee valve arrangements that two devices according to FIG. 7 are arranged which can, however, be actuated by a common slide 42. on In this way, one of the flow channels can be connected to a pump for conveying the washing liquid and the other flow = channel to a fan or the like. connected to the promotion of air will. The slide 42 can, before the actual program begins to run, can be made stationary by the program causing a fork 49 over the slide 42, which moves the slide 42 in the direction of the arrow 43 prevents the loading door 1 from opening during the program sequence is turned off.

In a further embodiment according to the invention according to FIGS. 1o to 12 is via a conveyor 50, which is attached to a drum attachment 51 of the Drum 4 is mounted and in an annular array of relatively small There is scoop 52, washing liquid when rotating the drum 4 through those Scoop 52, which are just passing through the area of the lowest level, in the collecting container 17 added to when this bucket 52 in the range of the highest Levels come, the same into a funnel-shaped gap 53 (Fig 11 and 12), which ends in the funnel 32 of the carrier R9, from which it is in the drum 4 and thus back into the ammel tank communicating with the drum 4 17 arrives, but before when passing the heat radiator 28 in the funnel 32 has absorbed heat. So that the Schöpfbehsilter 52, which, as shown in FIG can be seen to describe a circular path in a vertical plane, actually the washing liquid that they use in the lowest level, which is shown in Figs. 11 and 12 denoted by T, create, in the area of the highest level, which is denoted by H, can promote, it is necessary that the openings 54 of the Bucket 52 outside the areas T and H by two circular arc-shaped plates 55 are sufficiently covered that on the one hand at least no significant friction between the edges of the scoop 52 and the plates 55 and on the other hand but the majority of the scrubbing liquid scooped up in T is conveyed to H. can.

The arrangement of two opposing plates 55 makes it possible that regardless of whether the drum 4 is clockwise or counterclockwise Turns clockwise, washing liquid can always be conveyed from T to H.

As can be seen from FIG. 12, the lower opening of the funnel-shaped gap 53 on the blades of the fan or blower 36. This however, should not be mandatory within the scope of the invention. But the gap 53 could just as well in another place, for example between two of the three Heat radiators 28 shown in FIG. 12, open into the funnel 32 of the carrier 29. However, whoever directs the gap 53 to the blades of the fan is thereby determined is caused when the fan is naturally closed ventilation openings 6 is put into operation that the washing liquid flowing in through the gap 53 is atomized over the entire cross section of the funnel 32, which in particular then contributes to the rapid heating of the washing liquid if instead of the annular Heat radiator 28, as shown in Fig. 12, the heat = spotlights in the funnel "2 above the. -, ylzen cross-section of the same are arranged as pointed in the F. 'and 2, t and 6 as well as in FIG.

The fan or the blower 56 can either directly by means of a Electric motor, which is housed in the housing 56, the housing 56 with the Electric motor from the feed = door 1 can protrude so that the electric motor the influence of the heat radiator 28 is largely withdrawn, or indirectly via a shaft 57-58-59, on the one hand outside the carrier 29 with a drive 60 and on the other hand via a gear arrangement which is arranged in the housing 56 and with the fan 36 is in connection, are driven, as shown in FIG. 10 can be seen. The indirect drive of the fan 36 has the advantage that the Drive 60, for example an electric motor, is arranged outside of carrier 29 and thus on the one hand not the relatively high temperatures of the radiant heaters 28 and on the other hand not exposed to the moisture effects of the washing liquid If you want to refrain on the one hand, the electric motor with the necessary To provide protective equipment and on the other hand between the heat radiators 28 and also do not attach a partition 33 'designed as a reflector to the fan 36 wants, as was shown, for example, in FIGS. After the drive 60 for the fan 36 in FIG. 10 outside the carrier 29, which in turn is attached to the Loading door 1 is mounted, is arranged, must open the loading door 1 the shaft that transmits the rotary movement from drive 60 to fan 36 is interrupted, that is, can be uncoupled. This when opening or closing the Loading door 1 required uncoupling or coupling process takes place after the pipe coupling principle already described earlier, which is shown in FIG. 7 in the drawing is shown. If the pipe coupling in FIG. 7 is now used as a shaft coupling for the embodiment according to FIG. 10, the pipe = pieces 38 ', 39'- 45 - P, G in Fig. 7 in sequence with the waves = pieces 57 - 58 - 59 in Fig. 10. So there are the Shaft pieces 57 and 58 again in the Carrier 29, while the shaft piece 59 runs in the housing 22 and already the shaft of the drive 60 can represent. In Fig. 7 it is already shown that the slide 42 is not firmly connected to the driver 61, so that the slide 42 when the Arrangement according to FIG. 7 in a device according to FIG. 10 as a shaft coupling application finds, does not stand in the way of the rotary movement of the shaft. But will the arrangement 7 used as a pipe coupling, the slide 42 can with the Driver 61 be firmly connected. In the case of a pipe coupling arrangement according to FIG. 7 but it is also sufficient to firmly connect the slide 42 directly to the pipe section 45, so that the driver 61 is superfluous in this case.

If an arrangement according to Fig. 7 is designed as a shaft coupling, then this wave can be designed as a hollow as well as a solid wave and the sealing groove 47 is expediently replaced by a friction disk. Finally it should be stated that, if the spatial conditions permit, the Drive 60 (Fig. 1o) also in the carrier 29 behind the reflector 33 approximately at the point 60 'can be arranged, with openings 62 in the loading door 1 for cooling can worry.

In the embodiment according to the invention according to FIG. 14, the washing liquid by means of a pump 63 from the collecting container 17 via a line 64 which is connected to a of the two concentric tubes 65 or 66 is connected via the respective associated The annular gap or the associated annular nozzle 67 or 68 in the funnel 32 or sprayed directly onto the heat radiator 28 of the carrier 29, the washing liquid Absorbs heat and then enters the drum 5, from where it is returned to the collecting container 17 communicating with the drum flows to there again to be detected by the pump 63. Likewise, in the embodiment according to FIG. 15 the washing liquid from a pump, which is not shown in the figure represents = is set, received in the collecting container 17 and via a pipe 65 ', which in the distributor 68 'opens into the funnel 32 of the carrier 29 sprayed, after passing the heat radiator 28 through the protective grille 37 in the Drum 5 and passes from this through the holes 18 back into the collecting container 17.

In all devices according to the invention, it is useful that the Drums 4 or 5 not one in both the washing process and the drying process make steady movement in a single direction of rotation, but that it is known in Way change their direction of rotation in more or less large time = intervals, that means that they turn both clockwise and counterclockwise. The rotation of the drums 4 or 5 takes place relatively slowly so that the items to be washed or dry goods due to the centrifugal force not on the inner shell walls of the Drum 4 or 5 presses, but due to its weight, always from the higher Levels at lower levels of the drum 4 or 5 can fall, what on the one hand causes the items to be washed or dried to keep the fictitious elongated cone of the funnel 32 cuts, whereby an intensive contact between the washing resp. Dry = good and the radiant heaters falling into the drum 4 or 5 and / or the washing liquid or

Dry air is produced, what the washing or drying = process shortened and on the other hand has the effect that during the drying process the material to be dried is always loosened up again and thus becomes less wrinkle-free.

As stated earlier, the steps involved in washing are designed to be and drying in a device according to the invention by means of a program circuit being controlled. Program controls are well known and so it will in connection with the device in question not dealt with because this would go beyond the scope of the explanations. It should be noted, however be that the radiant power of the heat radiator 28 as well as the amount and the Temperature of the pumped washing liquid or drying air should be controllable.

In particular, the heat radiator 28 is intended to be an individual according to the invention Device consisting either of a single individual emitter or of several individual emitters exists, be easily controllable by the respective conditions according to the Power supply is varied and / or if the heat radiator 28 consists of several individual radiators is formed, individual radiators are switched off or on.

It is advantageous if the maximum emission of the heat = radiator 28 to the main absorption bands of water, which are known to be 1.4 and three or at six micrometers, is approached. The temperatures that the Heat radiator 28 has to be assumed in each case, can suffice well with the Wien's law of displacement can be determined. A preferred wavelength of the previously mentioned absorption band is the one at three micrometers, as this is after the spectral intensity distribution still provides sufficient radiation energy.

Since in the described devices according to the invention the washing liquid or the drying air is brought into contact with the heat radiator 28, comes it leads to a reduction in the temperature of the heat radiator 28, which is a lowering the frequency or an increase in the wavelength of the emitted radiation Consequence. Should a radiation with, for example, a wavelength of three micrometers are radiated into a drum 4 or 5, the temperature must of the heat radiator 28 can be increased by that amount than the temperature of the heat radiator 28 decreases by conduction through the washing liquid or the drying = air. Seen in this way, the amount of washing liquid in contact with the heat radiator 28 can be or drying air is also an instrument for varying the wavelength of the heat emitter 28 emitted radiation.

After the washing prcze # terminate @ i # t, :: Wnn in the known way the Drum can be brought to a relatively high number of revolutions so with the help of the ffi # entrifugal force ~ is spun out of the laundry in large part of the water, At the same time by means of a pump - in FIG. 14 a pump 63 is identical with that pump with which the washing liquid is sprayed over the heat radiator 28 - the water via a line 69, after the line 64 has been blocked beforehand through the two-way valve 53 'from the collecting container 17 into the drain (not shown ) is pumped.

With devices, in zones after the asoren, the laundry is also dried should be, but will vcm spin - at least from a too strong spin - It is not advisable to wash the laundry after washing, because the laundry is affected by centrifugal force is strongly compressed, which is also due in particular to the high water content, which the; 'åscìle has in it is reinforced. The laundry will do if only spun moderately or not at all, the drying process with a larger one Moisture content handed over, but since it was not pressed together = the water can be better drained from the laundry and the laundry will too crease less, as it can always move more loosely in the drum than if it had been thrown at a high number of revolutions. Finally be too also noted that in the construction of a device in which on the spinning is dispensed with, considerable savings can be made, since it is precisely the spinning puts an enormous mechanical load on the machine, which of course only made up for it can be built if the machine is built robustly, even if the Drying, by not spinning the laundry, a little more water can be removed must, from which a greater demand for thermal energy results, this additional demand lies a less robust and therefore less expensive machine design in terms of thermal energy and less wrinkled laundry at the end of the drying phase. In this connection but should already at this point on the utilization the waste heat from the refrigeration machines used to dry the laundry as will be demonstrated in detail later.

Before initiating the drying process, on the one hand, the entire Water must be pumped from the collecting tank 17 and on the other hand the ventilation openings 6 in the execution = forms according to FIGS. 1, 8, 12 and 13 are released, thus via this the fan or blower 36 cold air, with room air underneath that room is to be understood in which the device according to the invention is set up is, can be sucked in, and then passed over the switched-on heat radiators 28 to take up XL ^ # heat there and then finally to the drum 4 to be promoted, where the drying air in particular through the direct Effect of the heat rays on the items to be dried in the form of haze or water escaping steam is transported away.

Also in the embodiments according to FIGS. 5, 6, 14 and 15 takes place the removal of the surface water of the dry material or that from the dry material under the influence of radiation diffusing water by means of the heat radiators 28 heated air, but not directly by means of a in the funnel 32 of the carrier 29 arranged fan is promoted into the drum 4 or 5, but indirectly via a guide device 38 (Fig. 5 and 6) or via a connection opening 39 (Fig. 6) or via an annular gap or via an annular nozzle 67 or 68 (FIG. 14) or finally via a distributor 68 '(Fig. 15), which (r) each to a fan 36, which outside the carrier 29 at a different location (only shown in FIG. 15 visible ) the device according to the invention is connected, the air = circulation preferably takes place in a closed circuit, which will be discussed later will be discussed in detail.

This is also found in the embodiment according to FIGS. 8 and 9 The fan 36 is not in the funnel 32 of the carrier 29, but in a pipe 70 (FIG. 9), which can also be a conical tube, the beyond the drum 4 to the carrier 29 (Figure 6) opposite and into the front circular recess 71 of the Drum 4 protrudes, with a protective grille 37 closing the tube 70 on the drum side. In an embodiment according to FIGS. 8 and 9, the drying air is by means of Suction fan 36 through the drying = well sucked in the drum 4, since the dry goods is located on the suction side of the fan 36, while in a device according to Figs. 1 and 2, 10 to 12 and 13, the drying air through the dry material that is in a drum 4 was introduced, is pressed because the dry goods on the Pressure side of the fan 36 is located.

As with the other devices according to the invention, can also in an embodiment according to FIG. 9, the fan 36 by an electric motor which can be housed in the housing 56, are driven. However, if you want to, for reasons as mentioned earlier in connection with the embodiment according to FIG. 1o were to dispense with the use of an electric motor, the fan 36 in Fig. 9 are driven by the rotating drum 4 in that the Inside = side of the tubular drum attachment 25 equipped with a ring gear 72 is and via this ring gear the rotary movement of the drum 4 on a gear 73, which is attached to the tube 70, is transmitted, which rotation via a shaft 74 passes to a gear arrangement which is housed in the housing 56 and the fan 36 drives. Since, according to previous statements, the direction of rotation of the Drum 4 has to change constantly, but the direction of rotation of the fan 36 is maintained must be, is a known mechanism in the gear 73 or in the housing 56 built in that ensures this. another is said to be through an electromagnetic Coupling, which is either in the transmission 73 or in the housing 56, but preferably in the Gear 73 is arranged, switching off the fan 36 during the washing process be made possible.

The fan 36 according to FIG. 9 can finally also via a V-belt, the over the groove 75 of a V-belt pulley, which is at the rear end of the housing 56 is arranged or which takes up the space of the housing 56 at all and through the two slots 76 in the tube 70 to the V-belt pulley of an electric = motor leads, let this electric motor be the motor that also drives the drum 4 or be it an electric motor specifically provided for driving the fan 36 is to be driven.

The drying air, which absorbs moisture in a drum 4 or 5, leaves a drum 4 or 5 through holes 18 in which the carrier 29 is opposite End wall of a drum 4 or 5 arranged and / or through the holes 18 which are attached in the jacket of a drum 4 or 5 and is then over a Cooling surface 77 (Fig. 1 and 9) or 78 (Fig. 14) or 22 '(Fig. 15), where they have more or releases less of the absorbed moisture as a result of cooling, led to then either through holes (not shown) in a housing wall 22 of an inventive Device to leave the same or to then within the device of that Blower or fan to be sucked in again, this dry air already before has conveyed through the dry material in a drum 4 and 5, respectively.

After the heat radiators 28 radiate into the drums 4 and 5, Naturally, the walls of the drums and especially the front wall also heat up, which lies opposite the carrier 29.

Are in the front wall of a drum 4 or 5 from 5 flow = technical Arranged reasons holes 18, then pass through these holes 18 also the heat rays the heat radiator 28 on the cooling surfaces 77 or 78 or 22 'and heat them, whereby their cooling or efficiency is reduced.

To prevent this, between a drum 4 or 5 and one Cooling surface 22, 22 ', 77 and 78, a reflector wall 79 (Fig. 1 and 15) is arranged the rays impinging on them through the holes 18 on the end wall the drum throws back. Is the reflector wall 79 as a closed one Wall formed, that is, if it is not perforated, then the reflector wall 79 may are not brought up to the housing walls 22 and 22 ', but between Reflector wall 79 and the housing walls 22 and 22 'have to be column Bo (Fig. 1), so that the humid air flows via this to a cooling surface 22, 22 ', 77 and 78, respectively can be. The reflector wall 79 can, however, also be designed as a perforated wall be.

For example, the Tig. 3 such a perforated reflector wall 79. The hot air can in this embodiment via the holes 81 to a cooling surface 22, 22 ', 77, 78 arrive.

The reflector wall 79 can in this embodiment with the housing walls 22 connected. thus not again through the holes 81 heat rays on a Cooling surface 22, 22 ', 77, 78 can fall, the holes 81 are with overlaps 82 provided.

The reflector wall 79 can also consist of a device according to FIG 4 exist, as they already function in an inventive Embodiment according to FIGS. 10 to 12 has been described. During the washing process the openings 6 of the reflector wall 79 (FIG. 4) are closed by the wings 8 held, ss that when the reflector = wall 79 with the housing walls 22 of an inventive In front of the device is firmly connected and thus a column 80 (Fig. 1) is present, the cooling surface 22 ', 77, 78 is completely stripped from the washing process, also X7a3 Reduced heat loss during the washing process. Take in the drying process the wings 8 the position shown in Fig. 4, so that on the one hand on the Openings 6 the moist air to a cooling surface 22, 22 ', 77, 78 are brought up can and on the other hand in that a drum 4 or. 5 adjacent pages the inclined wings 8 are designed as reflectors, the heat rays, which fall through the holes 18 of a drum 4 or 5, thrown back be, so that a heating of the Künlflächen 22, 22 2 77.78 by direct radiation is avoided As can be seen from FIG. 15, there is only a small area the reflector wall 79 according to FIG. 4 from = formed, while the remaining part of the Reflector wall 79 air = impermeable and with the housing walls 22 is firmly connected.

The sense of attaching cooling surfaces 22, 22 ', 77, 78 in one The device according to the invention is that at least part of the gaseous State of the water absorbed by the dry air in the laundry is released to the laundry is, that is, condensed and the openings in, not shown, in Humid air escaping from the devices according to the invention - if the dry air is not performed at all in a closed circuit, as shown in FIG. 14 and 15 will be shown later - thus a lower moisture content = shows as if it had not been passed over cooling surfaces. One Reduction of the moisture content of the dry air exiting the devices is a necessity, because the places of use of mass-produced fixtures for washing and drying laundry or the like. are very different = good and not At each location it is irrelevant whether air often has a relative humidity of almost 100% is blown into the room and not every location has a suitable one Exhaust duct through which the humid air could be led directly into the open, but The locations of use are mostly rooms in which the saturated with water Humid air has a damaging effect on the equipment or facilities in these rooms Would have an effect and for this reason there is a reduction in the relative value Humidity of the air that leaves a device according to the invention is required.

In a simple embodiment, the cooling surface 77 can be identical with the rearward housing wall 22, as indicated in FIG. 1. The rear Housing wall 22 will then be made of a material with good thermal conductivity, so that the evaporation heat released during the condensation process is dissipated well can be. The rear housing wall 22, which, as already stated, acts as a cooling surface 77 can be designed, is expediently designed so that its heat-emitting Area is as large as possible, which is achieved by making the wall rib-shaped designed like that in Fig. 1 shown section recognizable is. As a rule, however, such a cooling method will not be very effective, since the devices in question are mostly set up in rooms in which room temperatures prevail and therefore only weak condensation processes can come. As a result, a number of more efficient cooling devices will be developed shown.

Another possibility, a housing wall according to the invention Using the device as a cooling surface is shown in FIG. In this embodiment are either two walls, namely a housing wall 22 'of the device according to the invention and a housing wall of a conventional cooling apparatus 83, for example the one Refrigerator, in direct contact or the device according to the invention and the Refrigerators 83 have a common housing wall 22 'as a partition, like that is shown in Fig. 15, the housing wall 22 'also as an evaporator of a refrigeration machine, which is housed in the cooling apparatus 83, can be formed. requirement for such a combination of washing machine and refrigerator are a matter of course the spatial setup options, which are certainly not available everywhere, but when they are there is a very economical and solid method to Drying of the humid air by means of cooling is given as the cooling unit of the cooling apparatus during the drying process on the condensation side of the invention Device generates the necessary low temperatures and thus on a cooling unit can be dispensed with within the device according to the invention. A good fridge or the like. this additional load during the drying phase of the invention Withstand the device safely. However, to the refrigerator in the time in which the The device according to the invention is not in operation, but especially during the Care must be taken to ensure that the washing phase is not burdened by the supply of heat that in these times between the refrigerator and the device according to the invention there is good insulation. For this Basically it is in the 15, the reflector wall 79 shown in a corresponding manner is also designed as an insulating wall. The wings 8 can also consist of a good insulating material.

On the other hand, however, that of the device according to the invention according to FIG. 15 and the cooling apparatus 83 common racing or

Housing wall 22 'made of a material that has good thermal conductivity owns. Thus, on the one hand, through the isolated reflector wall 79 and through the Openings 6 covered by the wings 8 of the cooling apparatus 83 during the washing process not exposed to the heat load by the device according to the invention and on the other hand but can in the drying phase with the wings 8 open the drying of the damp Air, which od from a fan 36. like., which is located in the wall 22 ' and 79 there is a limited cooling shaft 84 through which openings 6 are sucked, take place because of the good thermal conductivity of the designed as a cooling surface Separating or housing wall 22 'continuously absorbs the heat of evaporation released during condensation is discharged. The water precipitating on the cooling surface 22 'collects at the lowest point of the cooling shaft 84 and flows over a pipe or a Channel 85 into the collecting container 17, from which it is pumped out in a known manner. The inlet port 86 of the tube or the channel 85 can either by means of a Flegels 8 or by means of a known further valve not shown during the washing process as well as during the extra-ordinary time of the invention Device are closed, so that in particular during the washing process no water vapor can get into the cooling space 84.

Another possibility of the heat of condensation via a Ku - hI = to be able to dissipate surface 77 or 78, is that the cooling surface 77 or 78 is the boundary surface of a hollow body 87 (FIGS. 9 and 14), which is of a Coolant is flowed through, which continuously on the cooling surface 77 or 78 heat absorbs and discharges.

This coolant consists either of cooling water, for example Tap water, or from a refrigerant, as is the case with conventional chillers is used.

yomerstereuhlmittelb namely tap water, but can consist of several Reasons not used everywhere because the tap water network in the As a rule, it is always the same as the drinking water supply network and drinking water in many places becomes scarcer, so that the use of drinking water for cooling purposes economically seen is not justifiable everywhere.

From this point of view, the only effective coolant that remains is ultimately the refrigerants in the hollow bodies 87 (Figs. 9 and 14) which are identical can with the evaporators 87 (Fig. 16 to 19) of refrigeration machines, their flow diagrams 16 to 19 represent = are shown, evaporate and the when condensing of the water vapor carried by the air and coming from the laundry on the cooling surfaces 77 or 78 dissipate the evaporation heat released and thus the drying of the humid air cause.

The evaporator 87 can either be an absorption refrigerator (Fig. 16 and 18) or a compressor refrigeration machine (Figs. 17 and 19). Furthermore either a refrigeration machine in its entirety can be a device according to the invention belong to (Fig. 16 or 17) or there is only one evaporator 87 (Fig. 18 or 19) including the necessary ancillary equipment of a device according to the invention on, while all other devices of a refrigeration machine according to FIG. 18 or 19 components of a separate cooling device, e.g. a refrigerator, which is set up next to the device according to the invention, like that already has been described in an embodiment according to FIG. 15.

In the context of the invention, it should be immaterial which type of one Refrigeration machine is used. The only thing that is essential is the discharge of the at Condensation of the water vapor released heat, thus an optimal drying the moist air coming from a drum 4 or 5 can take place. The use of any Refrigeration machines should therefore be referenced by the following explanations the simple flow diagrams according to FIGS. 16 to 19 are not impaired, but the following representations are only intended to contribute to the functionality of the he = inventive devices to explain further.

First of all, the use of absorption chillers according to the Flow diagrams according to FIGS. 16 and 18 are treated.

The refrigerant evaporates in the evaporator 87 (FIGS. 9, 14, 16 and 18) when absorbing heat energy, which comes from the warm humid air, which over the cooling surfaces 77 and 78 (FIGS. 1, 9 and 14) delimiting the evaporator 87 where the water vapor carried by the air condenses and thus the air dried and cooled. The evaporated refrigerant is in the absorber 88 absorbed by the poor solution, with the released enthalpy of absorption dissipated must become. Since the absorption capacity increases with decreasing temperature, is afterwards to strive that the absorber temperature is as low as possible. With absorption of the Refrigerant turns the poor solution into the rich solution, either by means of a Circulation pump (not shown) or preferably by the thermosiphon effect - which comes about in that a heater 89 in a region of the pipeline 90 in this vapor = bubbles of the solution generated, which promote the rich solution -in the expeller 91 is promoted. The thermosiphon effect has the well-known advantage with the fact that absorption refrigeration = machines work without mechanically moving parts can.

Heat driver 91 is supplied with heat to the rich solution by a heater. In absorption chillers, this heating is usually especially for the expulsion purpose intended.

This is also the case when using an absorption refrigeration machine according to Fig 18 is the case in connection with a device according to the invention. However, this must not necessarily the case when using an absorption refrigeration machine 16 shows a device according to the invention, because in this case the heating of the expeller 91 also take place by a heat radiator 28, as shown in the 13 and 14 can be seen.

In these two embodiments, the driver is from 91 above a heat radiator 28, which thus fulfills three functions. He wears Firstly, it helps to heat up the washing liquid during the washing process. He wears secondly, during the drying phase to heat the drying air and the dry goods in a drum 4 or 5 and the same heat radiator 28 carries thirdly according to the invention for drying the moist air leaving a drum 4 or 5 by just, As already mentioned, this heat radiator 28 has the driver 91 according to the invention Device own absorption = cooling machine heated. As stated earlier the heat radiators 28 are stripped so that their rays predominantly only can radiate into a drum 4 or 5 through the drum opening 30. For the In the event that a poor radiator 28 is also provided for heating an expeller 91 is, this insulation is in the area of the heating surface 92 (Fig. 13) of an expeller 91 so reduced or replaced by a corresponding heat conductor that the heating of the expeller 91 can take place in an optimal manner. As before has been carried out, a heat radiator 28 from a group of individual = radiators be constructed. Since now in the final phase of the drying process from quality-saving Reasons usually the drying temperature must be reduced, which is due to Switching off individual radiators can be achieved, it is useful to = Provide the last individual radiator to be switched off for heating the driver 91, so that the absorption chiller continues to function until the end of the drying process remains guaranteed.

As soon as heat is supplied to the expeller, the dissolving power decreases of the solvent and on the one hand the refrigerant is expelled, which now reaches the condenser 93. On the other hand, the solvent also leaves in the form of a poor hot solution the expeller and flows through a pipe 95 and a throttle 96 in the absorber 88 back. Since, as has already been stated, the Performance of the absorber 88 with decreasing Temperature increases, it is recommended to use the poor hot solution on the way from expeller 91 to To withdraw absorber 88 heat, which is achieved in a known manner in that between the absorber 88 and the expeller 91 a countercurrent heat exchanger 97 incorporates, which on the one hand causes the rich and relatively cold solution that flows from the absorber via the pipeline 90 to the expeller 91, which is heated the heat requirement of the expeller 91 is reduced and on the other hand, causes the poor hot solution in tube 95 loses heat and with a more moderate temperature flows back into the absorber 88, which increases its efficiency.

In a device according to the invention with its own absorption refrigeration machine according to FIG. 16, however, the poor hot solution in the pipe 95 can additionally or exclusively Heat can also be withdrawn by the fact that one passes through the heat exchanger 95 'in the blower pipe 98 carries cold air, whereby the term cold air means either air, the just at the installation site of the device according to the invention by a fan Od. The like. Was sucked in or it is air that was previously on the evaporator 87 was cooled for the purpose of drying and now again for the drying of the damp Laundry items located in a drum 4 or 5 are to be used.

Likewise, the condenser 93 The heat given off can be used to preheat the drying air. Can do the same also apply to the waste heat of the absorber 88.

In this way, several heat sources are placed in the air flow of a blower or the like. switched on, the heat sources are increasing in the direction of flow To arrange temperature level, it being understood that as the last heat source a heat radiator 28 is arranged. By utilizing the waste heat in this way energy can be saved on the radiant heater 28, which increases the profitability of the Before = direction of the invention raises.

As can now be seen from the flow diagrams in FIGS. 16 and 18 is, the solvent takes the path in arrow = direction 99, while the refrigerant takes the path in the direction of arrow 100.

After the refrigerant after expulsion in the expeller 91 in the condenser 93 was liquefied, it flows via a line arrangement 101, 102 into one Throttle 103, through which the refrigerant is throttled to a low pressure, is built in, back into the evaporator 87, where it evaporates again, which also the cycle is closed.

Further devices according to the invention, as shown in FIGS. 16 and 18 can still be seen, will be discussed later after the general treatment of the compression chiller treated with analog facilities at the same.

In the compressor refrigeration machines shown in FIGS. 17 and 19 the evaporator 87 can again be identical to that of the cooling surfaces 77 and 78, respectively limited hollow bodies 87 (Fig.1, 9 and 14), on which the from a drum 4 or 5 incoming moist air cools with water release, whereby the released heat from the refrigerant vapor forming in the evaporator 87, which from the compressor 104 via a pipe arrangement 101, 1o2 is sucked in and compressed, is discharged. The condensed one Refrigerant vapor condenses while giving off heat in the condenser 93, wherein according to the invention the heat released can be used again to preheat cold air, by a fan or the like.

passed through the blower pipe 98 (FIG. 17) via the condenser 93 is then brought to the drying temperature at a heat radiator 28 and then introduced into a drum 4 or 5 for drying the laundry to become. Passes through a pipe 101 102 with an activated throttle 103 the refrigerant is returned to the evaporator 87, where it is again absorbed with heat evaporates.

Belongs to a refrigeration machine according to FIG. 16 or 17 in its entirety a device according to the invention, so can according to the invention in the pipeline 101, 1o2 between the condenser 93 and the evaporator 87 and here again before preferably between a valve 105 and a valve 103, which is a lockable Can be a throttle, an intermediate container that is not exposed to any significant heat source 1o6 are installed, in which at least a corresponding part of the refrigerant is stored during the washing process that the remaining refrigerant under the The influence of the washing temperature cannot be hazardous to pressure.

As has already been stated earlier, in a refrigeration machine according to an embodiment in Fig. 18 or 19 only the evaporator 87 with some necessary auxiliary devices, such as the valve 107 and the line branch 1o2 and optionally also the throttle 103 (only FIG. 18), to an inven tion according to the invention Device, while all other facilities of a refrigeration machine according to a 18 or 19 belong to a separate cooling apparatus, which is preferably in the connection area the device according to the invention is set up.

Thus, as can be seen from Figs. 18 and 19, each of these refrigerating machines has two evaporators, namely an evaporator 87 for a device according to the invention and an evaporator 108 for the main-purpose refrigerator. Is an inventive Device that is combined with a cooling device that is operated by a refrigerating machine is driven according to one of Figures 18 or 19, not in the drying phase or out of operation at all, valve 1o7 is closed and the evaporator 87 thus out of operation, while the evaporator 108 of the refrigerator is in operation can be when the chiller is switched on.

But if the device according to the invention is in operation, so is preferably set up at the beginning of the drying process by a program circuit of the device according to the invention, the valve 107, which - or at least its Switch or its electrical connections - if the inventive The device and the cooling apparatus are not connected at all to form a solid structural unit are, advantageously arranged on the outer wall of the cooling apparatus, so that Circuit and connection can be easily made, opened and the refrigerant comes in addition to the evaporator 1o8 via the evaporator 87 of the invention Device in the circuit of the refrigerating machine according to one of FIGS. 18 or 19. Since it is in a combined device of a device according to the invention and a conventional cooling device with a cooling machine after one of the two Fig0 18 or 19 can also happen that the operation of the inventive Device associated evaporator 87, but not the operation of the refrigerator associated evaporator 1o8 is necessary, a valve 109 is provided which is closed if necessary, whereby the refrigerant flow to the evaporator 1o8 the cooling device is interrupted. Only if neither the use of the evaporator 87 the use of the evaporator 108 is still required, the solvent flow should and / or the flow of refrigerant is stopped, that is, the refrigerating machine is automatically operated be switched off, or otherwise with the help of the simple circuit diagram according to Fig. Expressed 20, a refrigeration machine according to Fig. 18 or 19 should always switch on when as soon as voltage is applied to one of the two valves 107 or 109, what a Opening of the respective valve. For example, manages the program circuit of the device according to the invention, the drying phase, among other things voltage is also applied to a valve 107 (Fig. 18 or 19), which on the one hand causes that the energized valve is opened and, on the other hand, causes the switch 107 'assigned to the valve 1o7 (FIG. 20a) closes, with which already the unit 110 (Fig.2oa) also comes under tension. This unit 11o can represent the motor, which the compressor 1o4 of the compressor = refrigeration machine according to Fig. 19 drives or this unit 11o can be the heating for the expeller 91 or the heater 89 for the thermosiphon of an absorption refrigeration machine according to FIG. 18 embody or this unit 110 can be both a circulation pump, which instead of the thermosiphon occurs, as well as the heater for the expeller 91 of FIG. 18. Just as a switch 107 'is assigned to valve 107, a switch 109 '(Fig. 20a) is also assigned to valve 109 (Figs. 18 and 19), which closes when the valve logs through the switching of the cooling device causes a voltage to = is applied.

As in the simplified circuit diagram according to FiY. 20a can be seen is, on the one hand a refrigeration machine according to one of FIGS. 18 or 19 is set driving unit 110 always in operation when at least one of the two Switch 107 'or 109' closed, that is, on at least one of the valves 107 or 109 a voltage is applied and on the other hand the unit 110 is only then switched off when both switches 107 'and 109' are open (illustrated State), which means that neither of the two valves 107 or 109 is under tension and thus neither in the device according to the invention nor in the cooling apparatus, cold is required will.

According to a circuit according to FIG. 20b, the same effect is achieved as with a circuit according to FIG. 20a. The only difference is that that switches 107 'and 109' are not actuated by valves 107 and log, but that the switch 107 'is part of the program circuit of the invention Device and the switch log 'part of the circuit of the external refrigeration machine is and thus the switches 1o7 'and 1o9' directly from the respective program circuit be operated.

The throttle 103 (FIGS. 18 and 19) can flow in front of the valves 107 and or downstream. When connected downstream, as can be seen from FIG. 18 is, both in wiring harness 102 and in wiring harness 101, a throttle 103 required, while in the case of an upstream connection with a single choke 103 this is sufficient is found as shown in FIG.

As already stated, either the drying = air after it has absorbed 4 or 5 water on the damp laundry in a drum and afterwards it outside the drum for the purpose of drying the moist air on cooling surfaces Was cooled more or less, the device according to the invention by further not shown openings leave the same or the drying air is guided in a closed cycle. The routing of the drying air in the closed On the one hand, circulation has the advantage that the installation site of the invention The device is not subject to constant air circulation during the drying phase, which can be particularly uncomfortable if the place of use of the subject Machine is identical to a living space and on the other hand has the advantage that an Locations with high relative humidity with a smaller amount of air for the removal of an evaporated unit of water is found sufficient than if humid room air always had to be sucked in by the fan, because from quality-friendly For reasons related to the laundry, the warming of the air may have a certain temperature level do not exceed, so that the sucked in moist room air is always in spite of warming would be sent through the laundry with a higher relative humidity as a circulating dry air, with the assumption of course that In this cycle a cooling surface is switched on, where there is enough water can deposit. According to the invention, this circuit is according to the drying air 14 and 15 achieved in that a fan or blower 36 ( only shown in Fig. 15), which can also be a piston = blower, air via a funnel 111 (Fig. 14) or via openings 6 and the cooling duct 84 (Fig. 15) from a drum 4 or 5 at A, where it has a cooling surface 78 (Fig. 14) or 22 '(Fig. 15), where it gives off heat and water. This sucked in and air that has become poor in moisture on a cooling surface is blown by the fan or the like. compressed and when the device according to the invention is connected to a refrigeration machine is before or after the Compression through pipe 98 (Figs. 16 and 17) sent, where they can be found in the waste heat of the devices 93 and / or 95 'and / or 88 of the refrigeration machine is heated.

The air, preferably preheated in this way, is then on the pressure side of the fan via one of the connecting pipes 65 or 66 and the associated ring nozzle 67 or 68 (Fig. 14) or via the connecting pipe 65 'and the distributor 68' (Fig. 15) blown into the funnel 32 of the carrier 29, which is equipped with heat radiators 28, The air heats up at the heat radiators 28, which also increases their ability to Absorb water, further increases and then enters a drum 4 or 5 where they first pass the surface water and finally also that through the The effect of the heat rays diffusing from the inner fabric layers of the laundry Absorbs water.

It is preferable to use the drum for the entire drying time over short periodic times, once clockwise and then back again turn clockwise, as the laundry is in constant motion is located and so the drying air can be blown through much better what on the one hand quick drying and on the other hand also a crease-resistant dry wash as has already been stated earlier. Arrives in a drum 4 or 5 but the dry air, which is saturated with water, is already being sucked in again of the blower, which the humid air for water release or drying over again a cooling surface 78 (Fig. 14) or 22 '(Fig.15) leads, with which the circuit already closed is.

At the end of the statements about the device in question it should also be noted that between the individual embodiments described each Any combination can be employed within the scope of the invention, if this allows further advantages to be achieved.
