"Machine for cleaning especially non-iron laundry"

The subject of an older proposal by the applicant is an automatic one controlled by a program controller Machine for cleaning, in particular, non-iron laundry by washing, rinsing, smoothing and drying in hanging state in a washing and drying room provided inside the machine, which is in its upper part with a comb-like Support struts for the items of laundry to be suspended from them and is provided with spray pipes for the wash liquor or water to be pumped and for the one to be dehumidified and circulating dry air to be heated is to be applied. Due to the washing characteristic of this machine, Rinsing, smoothing and drying the laundry while hanging is gentle machine cleaning and overall care the laundry ensures what is particularly important for cleaning of non-iron, sensitive to mechanical loads Laundry is of great practical importance.

On the older machine, the comb-like laundry holding struts are in the upper part of the machine washing and drying room rigidly arranged so that for introduction

and removing the laundry, the machine cover must be opened. Furthermore, the spray pipes for the washing liquor and rinsing water supply are only arranged in the upper part of the washing and drying room, so that the hanging laundry items to be cleaned can only be sprayed with lye or rinsing water from above or outside. Furthermore, when the wash liquor is supplied continuously, there are undesirable changes or reductions in the wash liquor flow pressure, since the foam formation that occurs reduces the delivery rate of the pump that circulates the wash liquor in an uncontrollable manner. Finally, it has been shown that the drying effect to be achieved cannot be fully satisfied by the drying air circulating through the washing and drying chamber from bottom to top, as provided in the older proposal, because it sometimes leads to undesirable chimney effects, with the warm drying air can pass through the empty spaces between the individual laundry items without sufficient contact with the laundry.

The innovation is therefore based on the task of the washing machine according to the older proposal to improve and perfect it in such a way that it does not have the above-mentioned deficiencies, rather still It is easier to load and more effective washing, rinsing, smoothing and drying of laundry while hanging guaranteed. According to the present innovation, this is achieved essentially in that the laundry holding struts

are arranged on a laundry trolley that can be pulled out at the front of the machine, at least one spray tube also in the lower one Part of the washing and drying room is arranged to intermittently pump the wash liquor and the circulating dry air is to be led from top to bottom through the washing and drying room. With the pull-out laundry trolley laundry-holding struts which are preferably arranged to be foldable down and to be latched in their folded-up horizontal position the loading of the laundry cleaning machine is significantly simplified, since the individual items of laundry on the support struts of the machine front extended laundry trolley conveniently accessible hung or from the Retaining struts can be removed again. Since at least one spray lance, according to the innovation, also in the lower part of the washing and drying room is arranged, for example in the form of a spray arm rotating about its vertical central axis or in the form of two in the lower part of the washing and drying room near its opposite one The spray tubes, which are fixedly arranged at corner edges, can now also hold the items of laundry hanging on the retaining struts from below and are effectively acted upon in their interior by the washing liquor or the rinsing water, whereby the cleaning and The smoothing effect is still significantly improved. Furthermore, the washing liquor is pumped around intermittently ensures that the foam formation does not have a disruptive influence on the pump delivery rate, so that in

Maintain a more even liquid flow pressure in the spray pipes can be. Finally, it flows through the washing and drying room from top to bottom Circulating dry air achieves better drying in that the drying air is depending on the its temperature within the washing and drying room, as it were, automatically stratified. The upstairs in the drying room Incoming, relatively hot and dry air remains in the upper part of the washing and drying room until it cools down due to the absorption of moisture from the laundry and thus gradually sinks to the bottom. This avoids annoying chimney effects and the contact time necessary for drying the laundry with the Dry air reduced accordingly.

Another feature of the innovation is next to the washing and drying room and from it by a vertical one Separated partition wall is a narrow air shaft to which a coolant acts for the circulating dry air provided, the bottom and top over substantially horizontally extending chambers with the Washing and drying room is connected. The coolant used can advantageously be in the upper part of the air duct, about a third of his x * height, a sprinkling device should be provided, whose sprinkling jets on the outer wall of the air shaft are directed. Appropriately, it is in the upper connecting chamber

between deai air shaft and the washing and drying room that Circulating fan with a downstream heating device for the one flowing into the upper part of the washing and drying room Circulating dry air is provided, while the lower connecting chamber is opposite the washing and drying room above is covered by a perforated bottom plate and at the same time serves as a lye or water collection chamber, which has a a circulation pump for the line containing washing liquor or water with the spray pipes in the washing and drying room communicates. This leads to an extremely space-saving, very advantageous arrangement for the guidance, cooling and reheating of the circulating dry air with at the same time a very useful arrangement of the lye or water collection chamber.

The circulation pump is advantageous through a lye or. Water flow pressure to vary allowing poium switchable To drive the motor intermittently, the respective downtimes of the circulation pump preferably greater than whose pumping times are. In the case of those that are to be pumped over It has proven to be useful if the downtime of the pump is about 8 to 10 seconds, on the other hand, their pumping times are only half of that. The circulation pump to be driven by the pole-changing motor is intended, as experience has shown, for the good washing and rinsing of normal laundry at the junction with the individual spray tubes generate a minimum flow pressure of 0.5 atü, while this minimum flow pressure is used for washing and

Rinsing of delicate fabrics, such as wool, as well also in certain rinse sections for normal laundry to about two thirds to half of the normal pressure can be reduced. The ratios of the speeds correspond to the ratio of the flow pressures and thus also the Pdfcahlen the pole-changing pump drive motor, which is roughly 6: 4 or 4: 2.

The cost of such a circulation pump increases with the flow rate it delivers per unit of time must promote at the same pressure output. The flow rate per unit of time can, however, without impairment of the washing result be reduced if, according to a further feature of the invention, between the pressure port of the circulation pump and an electrically operated lye or water switch is arranged on the spray pipes. Supplied according to their position only part of the spray lance during pump downtime the switch can be switched to the next spray lance group.

With a view to achieving good washing, rinsing and smoothing result, the design of the spray tubes is also of particular importance. Here the innovation provides that at least the spray tubes arranged in the upper part of the washing and drying room above the retaining struts of the laundry trolley run parallel to the retaining struts, in each case at their ends facing away from the machine loading door to the detergent solution or water supply and with numerous

rich flat jet nozzles are provided with flat outlet cross-sections also run parallel to the retaining struts. Appropriately designed spray tubes can also be provided in the lower part of the washing and drying room «In both cases it is advisable to use the spray lance to arrange their longitudinal axes pivotably and they during washing and rinsing by an electric motor to set in pendulum oscillations. In this way, through the emerging from the flat fan nozzles Jets of caustic or rinse water sprayed the entire cross-section of the washing and drying room and thus that hanging laundry can be effectively acted upon by it.

Finally, the innovation also provides that several items of laundry can be hung on top of one another at intervals Spacers made of elongated, essentially U-shaped spacers can be used on the same laundry holding struts Profiled hollow bodies exist, which are provided with water and air passage openings over their entire length are. In this way, especially when cleaning large items of laundry that are folded in several layers and placed over the retaining struts, a better penetration or penetration of lye, rinse water and Warm air can be achieved.

Further features according to the innovation are based on the exemplary embodiments shown in the drawings described ^ n.

slot 4 '' 'and a support point 4 for the have essentially U-shaped profiled, downwardly open retaining struts 2 existing cross bolts 2 'or 2' '.

While the transverse bolt 2 'penetrates ^{the longitudinal slot 4 11',}

IV, the bolt 2 ¹ 'rests on the recessed support point 4 of the support strips 4''. As a result, the laundry holding struts 2 can be properly held or locked in their folded up position according to FIG ^I! can pivot past down. For loading and unloading the washing and drying room, the comb-like holding struts are moved out together with the laundry trolley 4 through the front door opening 3, whereby the individual items of laundry can be conveniently hung on the holding struts 2 or removed therefrom. In order to avoid, for example, a shirt hanging on a hanger or a lengthways

Direction of folded sheets when moving the laundry trolley 4 out or in at the lower edge 3 'touches the door opening, the clear height' H of the door opening should be at least about 1 meter and therefore also the cabinet-shaped machine have a corresponding overall height.

Above the laundry holding struts 2 are the upper spray tubes 5 with their flat jet nozzles at a distance WA (cf. FIG. 2) 6 arranged. The number of spray tubes 5 is for reasons of economic dimensioning of the Circulation pump limited to a maximum of 5, with three spray tubes 5 in the upper part of the washing and drying room 1 and in its lower part either two spray tubes 5 as in the case of FIG. 1 or as in the case of FIG. 2 a single spray tube arm 7 rotating about its vertical central axis is provided. The lower spray tubes 5 and 7 are each provided with upwardly directed spray nozzles. While the water or lye supply to the Spray tubes 5 on one side at their rear ends, it is in the rotating spray arm 7 in the middle from below Arranged coming, as shown in particular in FIG. 4 "The additional spraying of the laundry items from below especially with large laundry items that are folded up during the cleaning or care process Hang over the retaining struts 2, proven to be advantageous, because then the inner sides of the U-shaped downwards hanging laundry can be sprayed directly. Dominisrend

for washing and rinsing and above all for that However, the straightening of the laundry remains the same from the upper spray tubes 5 coming, downward spray tetratals. The design of the spray tubes 5 and the spray nozzles protruding from them are of particular importance for washing and smoothing the items of laundry. For this purpose, the spray tubes 5 are provided with flat jet nozzles 6 of the type shown in particular in FIG. 3. The ends of the spray nozzles 6 are therefore flattened or compressed. In this way, flat bundles are created Lye or water jets 8, which because of the parallel arrangement of the spray tubes 5 to the laundry holding struts 2 accordingly run parallel and thus also over a wide area and. with relatively large kinetic energy meet the individual items of laundry. This radiation effect on the one hand and the treatment temperatures occurring thermoplastic effect in the hanging laundry, the latter is stretched and thus effective smoothed. So that the flat jets cover the entire cross section of the washing and drying room 1 and thus also the suspended ones If items of laundry hit everywhere, the spray pipes 5 are pivotable about their longitudinal axes in the rear wall 1 ' the washing and drying room arranged and during washing and rinsing by an electric motor in pendulum oscillations to move. One possible embodiment FIG. 8 shows where the rear ends 5 'protruding backwards from the machine wall 1'

tubes 5 with links 5 ¹¹ are articulated on a common push rod 9, which is connected via the connecting rod 9 ¹ to the crank disk 9 ^{11 to be} driven in rotation by an electric motor. The pendulum oscillations of the spray pipes 5 to be generated thereby are in the Pig. 1 and 2 indicated by double arrows drawn. The distance WA of the upper spray tubes 5 from the laundry support struts 2 below should be at least 1/3 of the mutual spray tube distance so that the downwardly directed caustic or water jets can better penetrate the spaces between the hanging items of laundry.

Next to the washing and drying room 1 and separated from it by a vertical partition wall 10 is a narrow, Air shaft 11 to be acted upon by a coolant provided for the circulating dry air, the bottom and top over the essentially horizontally extending chambers 12 or 13 is connected to the washing and drying room. The air shaft 11 is in its upper part, about a third of its height, provided with a sprinkler H, the cooling water jets on the Outer wall 15 of the air shaft 11 are directed. This is done in the direction of the arrows circulating air is effectively cooled when passing through the air shaft 11, whereby the air in the circulating air Moisture is condensed, therefore a corresponding drying of the circulating air takes place. To circulate the

the flushing water via lines 24 and 25 to the spray pipes 5 arrives. The circulation pump 21 is by the pole-changing motor 26 and the water switch 23 by the Drive electric motor 27, both in a known manner by the program controller 28 or its corresponding relay being controlled.

Both the perforated floor plate 18 of the washing and drying room 1 and a ^{sieve 29 covering the sump drainage connection 12 · f} , the mesh size of which should be as small as possible than the width of the spray nozzles 6 in order to prevent them from being clogged by fibers or other impurities removably arranged so that they can be easily cleaned if necessary.

Like the Pig. 5 and 6 show that the laundry cleaning machine also includes a plurality of spacers 30, which from elongated, essentially U-shaped profiled hollow bodies exist, which over their entire length with water and air passage openings or slots 31 are provided are. As FIG. 6 shows, these spacers 30 are used to hang one above the other at a correspondingly spaced relationship to allow several items of laundry 32, 33 on the same laundry holding struts 2, their shape and improve training after the penetration or penetration of washing liquor, rinsing water and drying air, so overall ensure more effective cleaning and drying of the individual items of laundry hanging on top of each other.

In Fig. 10, the entire machine is shown in a diagrammatic, partially sectioned representation. The side walls of the washing and drying room 1 are provided with a heat insulating layer 34 from the outer cladding 35 is surrounded. The front door opening 3 is to be closed by the door leaf 36, which by means of the rubber seal 37 permits a watertight locking of the device. When the door is open, these are the bottom cover perforated sheet metal 18, the two lower spray tubes 5 and the comb-like struts 2 of the movable laundry trolley 4 visible in pushed-in position. The upper end of the Device forms the control panel 38 with the setting buttons, pointers and pushbuttons for the program controller and the order a lateral, vertical axis which can be swiveled out detergent dispenser bowl 39.
