Household device for washing and drying laundry, clothing and the like.

The invention relates to a household appliance which is suitable for washing laundry, items of clothing and the like in different ways, in particular with regard to the washing temperature. G

The currently common household drum washing machines are as to their practical use by a capacity on dry laundry of 4 ~ "6 kg and by the poss ~ the possibility of selecting different washing programs, in order to set some working parameters for the various types of laundry to be able to customize.

The household linen is intended for washing with household washing machines generally divided as follows:

1. White cotton fabrics or those in hard-wearing Colours.

2. Cotton fabrics in not very resistant colors and mixed fibers (cotton and synthetic fibers).

3. Synthetic fabrics.

4. Woolen fabrics.

Each of these different types of fabric requires washing in washing machines different modalities. The washing programs differ mainly in terms of how they are used the maximum temperature reached during washing and the average

execution or non-execution of the wringing effect Spin, with more complicated machines also changing the rhythm of the washing drum and the water level will.

If you only consider the wash cycle, these different wash programs will ultimately produce the Thermal effect (and thus at least partially also the chemical effect of the detergent solution) and the mechanical effect changes.

High temperatures (from 85-100 ° C) that are more resistant when washing and heavily soiled cottons are useful and often essential, in fact when washing of the following substances as too high:

- Mixed fiber and synthetic materials in which the compression caused by the mechanical washing effect is strongly impressed at temperatures of more than 55 "-65 * C or in which yellow discolouration or at least color changes can occur; '

- Cotton fabrics or other fabrics in colors that are not very resistant and which have a tendency to discolour (whereby the detergent ^{solution discolors) at temperatures above 5O-6O e C;}

- items of clothing that include additional items, which are damaged at higher temperatures, such as tapes, elastic parts, reinforcement inserts, etc.

As far as the mechanical effect is concerned, the rotation rhythms of the laundry drum, which are suitable for cotton fabrics, are suitable for

1 09821/1198

Mixed fiber and synthetic fabrics less suitable and for Woolen fabrics, also for those with felt-free equipment, the resulting matting is not permitted.

With a constant rotation rhythm of the washing drum, the mechanical effect can be reduced by reducing the times, increasing the liquid level in the washing container and by appropriately changing the amount of laundry items brought into the washing drum. a

The large number of household drum washing machines commonly used at the moment wash programs that can be carried out has limited practical value.

The housewife who washes one or more times a week, has accumulated a few kilograms of laundry, which comprises at least two groups, one of which (laundry that is at high temperature washable) over the others (laundry that can be ■ washed at a lower or lower temperature). This way she almost always uses the J wash program high temperature because it easily brings together a quantity of 3-5 kg of tough cotton fabrics while using them only rarely used the other washing programs, as it is difficult to find a corresponding one even in the course of a whole week Accumulates amount of laundry to be washed at lower temperatures. So to whom the economic side of washing is dear to the heart, which is often faced with the choice, often hand-washing certain items of clothing (shirts, socks, undergarments, etc.) or washing dirty clothing

to collect pieces for longer than a week in order to bring together such a quantity that a rational amount Machine washing is permitted.

Washing and drying devices are known in which the articles to be washed are already in the desired final state Form are suspended on supporting bars and in which these suspended articles are splashed and sprayed by several jets of liquid (detergent solution or rinse water) thus be shaken, so that the mechanical shaking action together with the liquid spray causes the detachment of the dirt from the exposed and also from the covered surfaces of the articles, while the liquid running down along the articles has such a smoothing effect that the washed and dried ones Articles can be used immediately or after a slight flattening.

The invention provides an apparatus for washing and drying, which has a closable cupboard container, a A plurality of support rods for hanging up the items of laundry and clothing to be washed, as well as a plurality of spray nozzles for spraying and shaking the suspended articles and is characterized in that the container is in its interior is divided into two rooms for washing delicate articles and for washing normal articles, which Rooms are each provided with their own means for spraying and shaking the items to be washed, with the Feed the into the room to wash the delicate items

introduced washing liquid at least one shut-off valve is, which can be actuated upon reaching a predetermined temperature suitable for washing the delicate articles is while heating the washing liquid and their Feeding into the other of the two rooms is continued.

By means of the inventive device, it is possible to undergo several articles under the most appropriate for the same temperature and other washing conditions a sub M retired union wash.

The main advantage of the invention. Device consists in the fact that this different washing by means of a single umpteen, simple and economical washing cycle can be achieved is.

As can be seen even more clearly from the following description, Another advantage of the device according to the invention is that when similar articles are introduced into the two Place the washing in both rooms un- ™ under the same conditions is possible while when introducing of washing at low or medium temperature Laundry in one room and from at high temperature too washing laundry in the other Hardly the operator the implementation of the different modes of treatment in can bring about the two rooms. The temperature change takes place by interrupting the washing liquid supply into the room intended for washing at a lower temperature as soon as the washing liquid reaches the said low

has reached a higher temperature while heating and the Washing is continued in the other washroom until the higher temperature is reached.

The mechanical shaking of the suspended articles can also be independent of the way in which it is brought about. be changed accordingly "

An exemplary embodiment of the device according to the invention is explained in more detail with reference to the drawing.

to facilitate.

The washing circuit comprises a single circulating pump 19 which sucks in the washing liquor from the common floor 20 of the two washing rooms and feeds it through a line 21 to the spray devices in the two rooms 11 and 12. A filter grille 22 is provided above the common floor 20 of the washrooms, which retains coarse impurities, while a further filter 23 for fine filtration is switched on in the pressure line of the pump IQ, so that clogging Λ of the spray nozzles is prevented. A drain pump 24 with a drain pipe 25 is provided for draining the washing and rinsing fluid at the end of each phase of the washing cycle. Finally, a schematically illustrated heating resistor 26 is provided for heating the washing liquid.

Each room 11 and 12 is provided with a spray device for spraying the articles suspended on the support rods 18, which consists of two rotatable spray arms 27A and 27B for the room 11 and, similarly, two rotatable spray arms 28A. and 28B are made for the space 12, which spray arms are through conduits \ 28 and 30 connected together in pairs and are provided in known manner with spray nozzles 31st In the example shown, the space 11 is intended for calving delicate laundry \ at a lower temperature, which is why there is a shut-off valve 34, which is preferably automatically controlled, in the line 33 branching off from the pressure line 21 of the pump 19 to the spray arms 27A and 27B. A second control valve 35, which can also be controlled manually by means of an operating button 36, is used to regulate the ...,

Liquid inlet to the spray arms 27A and 27B is provided.

To dry the washed wipes, each space 11, 12 is provided with a fan 37 and 38, respectively, by its own Motors (39 for the room 11, while the motor of the fan 38 is not shown) can be driven. The dry air circuit comprises the intermediate space 15 in which a shower 40 for condensation of the during drying developing water vapor and, if necessary, to remove the residual foam at the end of the washing cycle is. Suitable heating means (not shown) for the drying air are arranged at an appropriate point.

As already mentioned, one of the two rooms (in the example shown, room 11) is provided to accommodate any desired delicate laundry items at low temperature and possibly also with less mechanical effect to wash based on normal washing conditions. When the detergent solution is what is permitted for washing delicate items For this purpose, the shut-off valve 34 is activated by means of a suitable control (for example by a thermostat or a time control device), the wash liquor flow being diverted into the space 12 will. It should be noted that appropriate measures can be taken (for example throttle valves or By-pass valves) to prevent the temperature and the mechanical washing effect in the second space 12 due to the interruption of the washing liquor flow in, the room 11 is unfavorable to be influenced. Furthermore, the manual control valve 35 can be used for

Adjustment of the mechanical effect can be provided to the
Reduce the strength of the mechanical effect in the room for washing the delicate laundry, especially if the spray jets also have the task of causing the necessary shaking of the items to be washed.

It should be noted in this regard that, as has already been suggested, the hydraulic spraying devices themselves can produce the shaking by placing their jets on the articles to be washed in the vicinity of their suspension on the support rods
meet, while mechanical devices can be provided to set the support rods in the horizontal 'direction in vibration.

Finally, it is worth mentioning that it is with the inventive Device is also possible to dry the laundry to carry out different temperatures and for different times, which is particularly important when one takes into account that in the absence of the centrifugal effect for some types of textile fibers the drying time and temperature are considerable differ from those for other types of fibers.

It will be understood that the invention does not depend on what has been described Exemplary embodiment is limited, but that numerous variants are possible within its scope.
