Method and device for cleaning laundry.

The invention relates generally to a laundry cleaning method. In particular, the invention relates to a laundry cleaning method that is suitable with a limited
Amount of water to clean many types of fabrics that are commonly found in
automatic household washing machines.

The predominant method of automatic laundry washing
currently consists in immersing the laundry in a large amount of water containing soap or other detergent and agitating it in order to loosen and remove the dirt

109823/1655

remove, the soiled liquid pulled out of the laundry and then rinsing the laundry one or more times in a large amount of clean water. Despite This method, in which the laundry is well flooded, has a number of significant applications in its widespread use Disadvantages on. First, a relatively expensive machine is required for automatic operation. Although the Operational safety and the service life of automatic washing machines in recent years through essential technical Port steps have been greatly improved, there are still many different complex systems for the water supply that Circulation and water drainage and similar complicated parts of the reversible motor, the power transmission and the Drive elements, the vibration protection and the control mechanisms. All of these elements, which are essential for the automation of the desired washing process, can by any Failure fail.

Another disadvantage of the washing process with flooded Laundry consists in the requirement of large amounts of water, which are usually heated. With an average wash Today, more than 150 liters of water are used, which is heated to around 50 ° C. Consequently, in the household of a family, where the automatic washing machine every day one or carries out several washes, the effort required for water, water heating and sewer connections is very considerable will.

Because of these problems and disadvantages inherent in the washing process with submerged or flooded laundry It is an object of the present invention to provide a new and improved method of cleaning laundry to create that only requires a limited amount of water, which does not need to be heated. Also included the invention includes such a process carried out in a suitably modified automatic dryer can be, so that thereby the complex washing systems one

automatic washing machine can be avoided. In the end It is the object of the invention to provide a new and improved method for cleaning fabrics, which the The effect is that certain stains are removed or at least weakened by cleaning with the normal washing process with flooded laundry, as is done in a household washing machine.

In short, the objects are achieved according to an embodiment of the invention by a method for cleaning Laundry dissolved in which the laundry or the fabrics together with a certain amount of water, detergent and a means of transmission overturned or mixed up |

will. The transmission medium is preferably from a Material is formed which has a large surface area per unit mass, and the water is only in such an amount present that it is sufficient to moisten the laundry. The agitation causes the water, detergent and the transfer medium come into contact with the laundry and the dirt from the laundry is distributed over the surface area that of the laundry and the transmission medium together is formed. Subsequently, the contaminated transmission medium separated from the laundry so that the laundry is cleaned of the dirt spread on the transfer medium is.

Furthermore, according to the invention, an improved device is created, to perform the above procedure. This device includes an automatic household tumble dryer, which is designed for drying fabrics or laundry by placing them in a container that is around a non-vertical Axis is rotatable, thrown around or overturned. The tumble dryer contains optional switchable devices, which can be used to heat a stream of air and circulate it through the container to remove moisture from the laundry. When carrying out the cleaning process in this device, the substances to be cleaned are together with a certain amount of water, detergent and transferred

given in the rotatable container. The means of transmission preferably contains a material with a large surface area per unit mass, and the water is only in in an amount sufficient to moisten the fabrics. The container is then rotated, using the device for heating and the air is essentially switched off, so that the laundry, the water, the detergent and the transfer medium without substantial drying of the laundry to be mixed up. This cluttering causes the dirt from the laundry on top of that from the laundry and areas formed together is distributed to the transmission means. Subsequently, the contaminated transmission medium separated from the laundry so that it is cleaned of the dirt which is distributed in the transfer means.

The invention will now be understood from the following description and the accompanying drawings of preferred embodiments explained in more detail according to the invention.

FIG. 1 is a side view of the clothes dryer used for cleaning fabrics according to the method of the invention suitable is.

Figure 2 is an electrical schematic diagram and shows a control circuit for the dryer according to FIG.

FIG. 3 is an illustration of the sequential circuit and shows the positions of the switches in the circuit diagram according to FIG during the operation of the machine according to Figure It

According to a main feature of the invention there is a new and improved method of removing soil from laundry or substances created. The term "dirt" here refers to both oleophobic oil-like materials, such as. B. Body oils, cooking oils and tallow and similar solid substances, such as e.g. B. clay, sand, dust, gravel, pumice stones

109823/1655

- 5 and the like, which are essentially non-organic in nature.

The cleaning of laundry according to this method, which is hereinafter referred to as the "dry washing method", uses only a limited amount of water which is sufficient to moisten the laundry. Although heated water can be used, the method can also be carried out with unheated water. The term "moistening" means that the fabrics are wetted to such an extent that some free water is present on their surfaces during the cleaning process. The free water should be present in an amount sufficient to give the detergent used in the cleaning process some mobility so that it is distributed over the entire surface of the laundry and the transfer medium. In this connection it has been found that an amount of water of 50 to 150 % of the dry weight of the laundry is sufficient, the exact amount depending on the type of laundry to be cleaned. In order to speak more clearly, it should be said that about 1 1/2 liters of water can be used for 1.4 kg of cotton laundry to be cleaned.

To increase the wetting effect of the water and to support the dissolution and removal of dirt from the laundry, a certain amount of detergent is used in the dry washing process. The detergent used can be a commercially available or a specially specified liquid or powder detergent, which additives, such as B. germ killers, optical brighteners, Deodorants, etc., may contain. One such commercially available liquid detergent which is used in the Dry washing method has been used with success is that detergents sold by Procter & Gamble under the trade name "Cinch". A lot of 75 grams of "Cinch" that was used with 1 1/2 liters of water per 1.4 kg of laundry, has shown to be sufficient.

109823/1655

It should be noted that 75 grams of detergent, such as. B. "Cinch", which was used with 1 1/2 liters of water, provides a much higher concentration of detergent than when it is used in conventional washes with flooded laundry. In other words, an essential feature of the invention is that the laundry is exposed to a detergent concentration that is many times higher than in the normal wash cycle, in which, according to a typical example, approximately the same amount of detergent, ie 75 grams per 57 Liters of water is used. In addition to being good at removing dirt, the high detergent concentration has the further advantage that certain stains which withstand normal washing are removed or weakened by this cleaning process.

In order to clean the fabrics or the laundry, the dry washing process relies on the use of a transfer agent. This means of transmission, which ideally from a material having a large area is repeatedly brought into contact with the laundry. Through this causes the dirt to be loosened from the laundry and this dirt to be transferred to that of the transfer medium and the laundry is distributed together formed surface. The transfer agent acts both as an abrasive, to support the removal of the dirt from the laundry, as well as a collection means to a considerable extent To hold on to part of the loosened dirt.

The repeated contact of the transfer agent and the laundry can be achieved in a simple manner in that the laundry, the water and the detergent in a container that can be rotated about a non-vertical axis the transmission medium is brought into contact. As a container, for example, the drum of an automatic Serving household tumble dryers with a horizontal axis. An automatic clothes dryer, the appropriate improvements

109823/1655 '

has so that the dry washing process can be carried out will be described later.

In the preferred method, the transfer medium is used together thrown together with the laundry so that repeated contact is brought about between them. as A number of materials can be used for transmission means. However, it is important that the material used has a relatively large surface area per unit mass and that it has a compatible affinity for the Laundry has dirt to be removed, so that the dirt can be absorbed by the transfer means. Included the effect of the transfer agent can be enhanced by a suitable treatment, to its affinity for Enlarge dirt. Furthermore, depending on the circumstances, the transmission medium can either be or be reusable be thrown away after cleaning. Of course, if the transfer agent is cheap enough that it can be used can be thrown away in a single use, there arises the problem of cleaning the transfer medium for reuse not on.

It should be noted that the transmission medium used is chosen in this way may be that it lends itself to an automatic separation, so that the complete dry washing process is then automatic and can also be carried out automatically after other wash cycles.

Suitable materials that are successful as a means of transmission were examined are, for example, velvet strips, Foam rubber and plastic foam blocks and particles of various configurations, sponges and the like. A transitional agent that is beneficial for use in conjunction with the dry wash and dry rinse processes appears is polyethylene foam. Polyethylene foam has the advantage that it shrinks when heated, so that the contaminated transmission medium, once it has been removed from the

109 8 23/1655

Laundry is separated, can be significantly reduced in volume by the heat shrinkage in order to remove it to facilitate

In connection with a load of 1.4 kg laundry is 57 grams Polyethylene cubes with an edge length of 6 mm have been used successfully. This amount of the transfer agent can be used as Volume of about 2 liters of small, elastic foam cubes can be better illustrated.

Another possibility of washing with the transfer medium to bring into contact is to apply the transfer means to the inner surface of the laundry container. For example suitable parts of the inner surface of the drum can be covered with a removable strip-like transfer medium will. Then, when the drum rotates, the laundry is repeatedly in contact with the transfer means while the laundry and the transfer medium in the drum are thrown around irregularly.

With the dry washing method, the laundry can be put in the drum an automatic household dryer with a horizontal axis, which has certain improvements to be explained later, be introduced together with the water, the detergent and the transfer medium. The dryer drum or the container is then rotated, whereby the laundry is subjected to a circulation action, so that the water, the detergent and bringing the transfer medium into contact with the laundry and removing the dirt from the laundry over the exposed ones Surfaces that are formed by the laundry and the transfer medium together is distributed. The bigger the surface of the transfer agent, the greater the amount of dirt that is removed from the laundry and is distributed to the transmission medium. Such a distribution of the dirt creates surfaces with dirt concentrations essentially avoided on the laundry.

109823/1655

Furthermore, due to the high concentration of detergent and the repeated contact between the laundry and the Transfer agent weakens or removes many, if not all, of the stains in the laundry.

It should be noted that this new and improved method To clean laundry the water and the detergent solution are not used as a carrier for the Picking up dirt from the laundry and holding it and then directing it to the drain. The dry washing process uses the water and detergent rather to moisten the laundry and to loosen the dirt, so that by repeatedly touching the laundry with the transmitted " supply means and with other laundry items a complete distribution of the dirt over that of the laundry and the transfer medium together formed surfaces is brought about. Although a certain amount of dirt remains on the laundry, the dirt is significantly reduced and distributed by this process compared to the original amount of dirt, so that no undesirable areas with concentrations of dirt remain.

After circulating in the drum, the soiled transmission means is removed from the laundry, so that the laundry is clean overall ä from the transmission means on the distributed dirt. Such separation can be brought about by a mechanical device suitable for receiving the particular transfer medium being used, or the transfer medium can be manually removed from the laundry. An automatic solution will then be discussed in conjunction with a special automatic household drying device.

According to a further feature of the invention, the laundry can then be dried by placing the laundry in the container is circulated while warm dry air is passed through it will. Such a subsequent drying stage is suitable

in an automatic household tumble dryer in particular, even if the first cleaning process in such a improved dryer was carried out.

In order to carry out the dry washing method according to the invention in an automatic household laundry drying machine, a number of modifications and improvements to the machine are required. For a better understanding of this, let initially referred to FIG. Here, an automatic household tumble dryer 10 is shown having an exterior Has protective housing 11 with a door or a lock 12. This allows access to the interior of the housing arranged to put the laundry in and out. A control panel 14 is located on the upper part 13 of the housing 11 provided, which can usually have a suitable hand control 15, the one built into the control panel 14 Control device 16 is connected. By manual setting of the controller 15, the machine is switched on and runs automatically over an operating cycle.

Within the housing 11, a laundry container or drum 17 is provided, which around a substantially horizontal Axis is rotatable. The drum 17 has a substantially cylindrical shape and has a cylindrical one in the center Wall section 18 and outer cylindrical wall sections 19 and 20, which are arranged in a corresponding manner next to an annular front wall 21 and a circular rear wall 22 of the drum are. The wall sections 18, 19 and 20 are essentially impermeable to the drum or container 17 Hold water approximately 1 inch (2.5 cm) deep. There are numerous on the inner surface of the wall section 18 Ribs 23 for circulating the laundry so that it is lifted when the drum rotates and then onto the floor the drum can fall back. The front part of the drum 17 can be inside the outer housing 11 by corresponding Let-trider be rotatable, one of which has a guide wheel through reference number 24 is indicated. These wheels are rotatable on

attached to the upper part of an element 25 which protrudes upward from the lower part 26 of the machine. The wheels 24 are below of the drum and engage the section 19, so the section 19 on each side for a stable Support bracket.

The rear end of the drum 17 is held by a pin shaft 27 which protrudes from the center of the wall 22. This shaft 27 is held in a bearing 28 which is formed in a wall structure 29. This in turn is rigidly attached to the rear wall 30 of the housing 11. The fastening can be done somehow and for example by welding | take place at numerous points 31. With the arrangement shown, the drum can rotate about a horizontal axis, wherein the wheels or rollers 24 in front and the trunnion shaft 27 in the bearing 28 at the rear for a bracket.

In order to ensure a flow of drying air through the laundry drum, it is provided with a central opening 32 in the front wall 21 and numerous small holes 33 in the rear wall 22. In the illustrated embodiment, the small holes 33 are formed in an annular space around the rear wall. The opening 32 is aligned with the opening in the housing 11, which is capping through the door 12 * bar and thus serves a dual purpose in that it also serves as access to the drum 17, the laundry fit and remove.

As already mentioned, the wall structure 29 is rigidly attached to the "rear wall 30" of the housing. This wall structure 29 is used also for holding a heating device 34, which has two electrical Resistance heating elements 35 and 36, which are isolated from the wall structure 29 in a suitable manner. the Heating elements 35 and 36 can be annular so that they take approximately the same course as the small holes 33 in the Drum 17. A wall 37 is on the rear wall 22 of the drum 17

109823/1655

outside the ring of small holes 33 and inside the fixed wall structure 29 firmly attached so that an annular air inlet 38 is formed through the walls 29 and 37 is. In this way a channel is formed for the air to enter the inlet 38 between the walls, via the heating device 3 ** strokes and then through the in the Openings 39 formed in the wall 37 and arranged in the middle, and the small holes 33 in the interior of the drum 17 flows.

The front opening 32 of the drum is closed by a fixed closing wall, generally designated by the reference number is designated. This closing wall 40 comprises numerous contiguous parts including the inner surface 41 of the Access door 12, a fixed frame 42, which acts as a Flange is formed on the front wall 43 of the housing, an inner surface of an output conduit created by the interaction of the part 44 and the front wall 43 of the housing is formed, and an annular flange 45 which on the frame 42 of the front wall 43 is attached. It should be noted that there is an appropriate clearance between the inner edge of the Opening 32 and the edge of the closing wall 40 is provided so that the drum and the closing wall during the drum rotation do not rub against each other. In order to avoid significant air leakage through the opening 32, attached to the flange 45, a ring seal 46, which with the outer surface of the drum wall 21 forms a seal. The door 12, the inner surface of which is part of the area that closes the opening Forms closing wall is attached to the housing 11, so that with the door open, the laundry is inserted and through the Door frame 42 can be removed through from the drum. It should be noted that the door has an outer, flat and impermeable portion 47 and an inwardly protruding hollow portion 48 attached to the flat outer portion is appropriate. The hollow interior portion 48 protrudes into the door frame 42 when the door is closed and the door surface 41, which forms part of the closing wall 40,

109823/1655

- 13 is actually the inner wall of the hollow section 48.

The air is removed from the drum by a calibration Opening 49 composed of a plurality of individual holes and formed in the inner wall 41 of the hollow door section 48 is. The bottom wall section of the door 12 and the adjacent wall of the door frame 42 are aligned with openings 50 and 51, wherein the opening 51 forms an access to a line 52, which through the interaction of the part 44 with the front wall 43 is formed. A collecting container 53 can may be provided in the outlet conduit 52- within the opening 51 and held by the door frame M2. The administration 52 leads down and stands with a housing 54 in Link. This housing 54 contains a fan 55, which is driven by a motor 56 via a clutch 57. The fan draws heated air through the line 52 and then guides it from the housing 11 through a suitable, line not shown through it.

In addition to the drive for the fan, the motor 56 takes care of the Rotation of the drum 17 · To bring about this rotation, the motor 56 is provided with a shaft 58, on one of which At the end there is a small pulley 59. A belt 60 runs around the pulley 59 and also completely around it the wall portion 18 of the drum 17 around. Due to the relative circumferences of the pulley 59 and the wall section 18 the drum is driven by the motor at a suitable speed to keep the laundry in the drum messed up is thrown. In order to ensure that the belt 60 is properly tensioned, a suitable tensioning device 61 is attached to the belt attached to the same bracket 62 which supports one end of the motor. Thus air is drawn through the drum, and at the same time the laundry is thrown together inside the drum. When the air is heated by the heating elements 35 and 36 the heated air flowing through the drum ensures that the moisture from the laundry evaporates, and that at the same time generated steam is discharged together with the air when

109823/1655

this emerges from the machine.

FIG. 2 shows a schematic circuit diagram which shows a basic or simplified control arrangement for the dryer according to FIG. It should be noted that many subtleties, such as. B. Teraperaturwähler, selector for the numerous programs and on the laundry temperature or on the resistance responsive controls for an automatic termination of the dryer operation, etc. are not shown in the circuit diagram according to Figure 2 in order to obtain a simple representation. As can be seen from FIG. 2, the entire control system of the machine can be supplied via a three-wire network, which comprises feed conductors 63 and 64 and a center conductor 65. In household use, conductors 6 and 6 ¹ »are normally connected to a 230 V network, with a voltage of 115 volts between the center conductor 65 and each of the conductors 63 and 6H , and the center conductor being grounded. The motor 56 connected between the conductors 63 and 65 is a single-phase induction motor with a main winding 66 and a start-up winding 67, both of which have a common end on a conductor 68, via an ordinary door switch 69 (which is closed when the door is closed and when the door is open Door is open) the conductor 68 is connected to the conductor 65.

The starting winding 67 is connected in parallel to the main winding 66 under the control of a speed-dependent device. The speed-dependent device is shown at 70 and is connected to the rotor 71 of the motor according to the schematic illustration in this figure. The speed-dependent device 70 controls a switch 72 which is to be brought into engagement with either a contact 73 or a contact Jk. When the machine is in the rest position, the switch 72 is connected to the contact 73, and it acts on the contact 7 ^ when the motor reaches a certain speed. It becomes clear that when the contact 73 is engaged, the starting winding 67 is connected in parallel to the main winding 66

109823 / 165S

and the start-up winding circuit is opened when si2h der Switch 72 moved away from this position. Thus, when the rotor 71 reaches a certain speed, it becomes the starting winding is switched off, and the motor continues to rotate due to the field generated by the main winding 66 alone.

The start-up of the motor can be brought about by a manually operated switch 75 which, for example according to the design shown in FIG. 1, can be brought into its closed position by pressing down the manual control 15. The switch 75 connects the motor via the contact 76 of a switch 77 to the power line. The switch 75 is normally open, as shown in FIG. 2 f. When the hand control 15 is depressed and it is assumed that the contacts 76 and 77 are closed, the motor 56 is energized and in less than a second the motor will under normal circumstances reach a speed at which the switch 72 will move away from the Contact 73 moved to contact 7h When the manual control 15 is released so that the switch 75 is opened again, the main winding 66 of the motor 56 continues to be fed via a secondary path around the switch 75 due to this movement of the centrifugally actuated switch 72 .

The switch 77 is controlled by a Nooke 78, which in turn g by a timer motor 79 of the closing or timing control apparatus is controlled. The nooke 78 and timer motor 79 are also connected to the handset 15 so that rotation of the handset causes the nooke to rotate and switch 77 to close. Thereafter, the nooke 78 is controlled by the timer motor 79, and after a predetermined period of operation of the timer motor, the nooke causes the switch 77 to be opened to terminate or pause the operation of the machine.

Further, a feed circuit for the heater ~ 5k is formed by the following circuit. Starting at the line

1 0 9 8 2 3/1 G 5 5

ter 63 continues the circuit via a switch 80 and a drought sensing thermostat 81 to heater 34 and then through a conventional safety thermostat and via switches 83 and 84 to conductor 64. Of the Switch 80 is controlled by a cam 85 which in turn is controlled by the timer motor 79. The desk 83 is controlled by a solenoid 86 and is normally closed when solenoid 86 is not energized is. The switch 84 responds to the centrifugal force at the respective speed of the rotor 71 and is only closed when when the motor 56 reaches a certain speed has so that the heater 34 is fed only when the motor 56 is working properly. The thermostat is 8l arranged to sense the temperature of the laundry in the drum 17 or a temperature which is substantially different changes directly with the laundry temperature. If the laundry is at a temperature that indicates dryness, so the thermostat 81 opens, whereby the heating device 34 is switched off.

With the possible exception that the wall sections 18, 19 and 20 of the drum 17 are without an opening, the above description is substantially consistent with the configuration and arrangement of known automatic household dryers.

In order to carry out the dry washing process according to the invention in the machine according to FIG. 1, it is necessary that the device which heats and circulates the air moving through the container is selectively feedable. Be it advised that it was during the dry wash cleaning cycle it is desirable to switch off both the device for heating the air and for circulating the air or to make it practically ineffective, so as to prevent undesired evaporation of the limited amount of water required for humidification the laundry is used to avoid.

Therefore in accordance with one feature of the invention is a control device provided, which is able to use the device for

109823/16 55

disable the air circulation or fan 55 and heater 34 so as to rotate the drum or container 17 with either heated air passing therethrough or not. Such a one Control, for which in Figures 1 and 2 an embodiment Shown includes a solenoid 86 that connects on one side to the center conductor 65 and on the other side across a switch 87 is connected to the conductor 63. The switch 87 is controlled by a cam 88, which in turn is controlled by the timer motor 79. The solenoid 86 actuates an armature 89 which, when the solenoid 86 is energized is, the motor 56 separates from the fan 55 by means of a clutch 57 I and which opens the switch 83 at the same time. If so the solenoid 86 is energized, the fan 55 and the heater 34 are switched off.

As best shown in FIG. 1, the clutch 57 has two frictionally engaged parts 90 and 91, the part 90 being connected to the output shaft 58 of the motor 56 and the part 91 being connected to the fan 55. The parts 90 and 91 are normally held in the drive position by means of a compression spring 92. However, when the armature is moved 89 by energizing the solenoid coil 86 in this, the lever 93 which is pivotally supported at 94 and is secured via a similar joint 95 to the armature 89 separates the part 90 from the part 91, thereby the fan 55 is disconnected from the motor 56.

It will be apparent that a number of other systems can be provided to provide the heating and circulation apparatus shut off the air or render it essentially ineffective. For example, it could be in the air flow line at the inlet or outlet of the blower a valve could be attached, or the air flow could be diverted so that it does not passes through the drum. A large number of such modifications are known to those skilled in the art. If further first very cold water is poured into the dryer drum 17

109823/1655

is conducted, it may be desirable to heat the dryer drum to bring the drum temperature to the desired level Bring area for cleaning. To achieve this, a separate heating device can be provided, or the heater 34 can be controlled with appropriate controls be used for this purpose.

For operation, the machine according to FIG. 1 can have programs that it carries out the entire punctures with regard to cleaning, the separation of the transmission medium and the drying, or only individual punctures thereof. The cams 85 and 88 can be designed so that the switch 87 is closed during the cleaning cycle, so that the magnetic coil ^{switches off the fan 55 and the heating device 3 1} *, while the switch 87 is open during the drying cycle and the switch 80 is closed. As can be seen even better from FIG. 3, this arrangement means that the fan 55 is switched off during the cleaning process. In the drying cycle, however, it works continuously, while the heating device 34 is switched off during the cleaning cycle and can be switched on during the drying cycle under the control of the scanning device 81.

In order to carry out the dry washing process according to this invention in the machine of FIG. 1, the machine to be cleaned Put laundry in the drum I7 together with an amount of water, detergent and transfer agent described above. The hand control 15 is then operated to start operating the machine in the dry cycle, with the heating device 34 and the fan 55 are switched off during the rotation of the drum 17. The laundry, the water, that Cleaning and transfer agents are thereby mixed up, so that the dirt and the cleaning agent from the Laundry about the together of the laundry and the transfer medium surfaces formed are distributed, as described above. After this circulation, separation can take place of the transmission means automatically during the first part

109823/1655

the drying cycle can be brought about. For example, if the transmission medium is used in cubes made of polyethylene foam is, these cubes have enough buoyancy so that they by the introduction of the air flowing through them from the Chamber 17 can be carried out. These cubes can then be stored in a collecting container 53 or a similar device be caught. Alternatively, such a separation between the cleaning and drying aisles can be done by hand be performed.
