FR1449949A - Double machine for washing dishes and linen and multiple combinations - Google Patents

Description

Double machine for washing dishes and linen and multiple combinations; The object of this patent is, inter alia, to economically produce a new product, in one form, two super laundered or juxtaposed washing machines, one used to wash the laundry and the other dishes, at the same time. The use of common organs such as, for example, a common pump and a pressurized air generator common to both machines. Eventually the latter will be the vibrations of ultrasounds, or sounds, or infra-sounds, produced, for example, by fixed or adjustable frequency sifflets. These whistles are, as usual, actuated either by the passage of water or by that of air, of said pump and of said air generator alternately or concomitantly.

The kind of pressurized air generator is indifferent and can therefore be constituted by a compressor, or by a turbine, or by a blower or by a fan or other, such as, for example, a household vacuum cleaner.

This patent also relates to the characteristics listed herein and considered in isolation or in partial or total combination. One of the characteristics in question is the use of common ganes without, for this, in some of the instructions for use below, that the water and air used by the dishwashing machine may be soiled by a passage through the washing machine. <I> Washing machine 1a dishes </ I> Fig. 1 gives a vertical section without the inlet and exhaust tubes and the like are connected, as they are in reality, by pipes whose arrangement on the lateral side of the machine, is provided by FIG. 2. The machine comprises the upper compartment 1, the water pump X and the pressurized air generator H placed in the intermediate compartment 2. The latter is divided into two distinct parts by a partition which offers the advantage, from the electrical point of view, to completely separate the electrical control unit b and the O and Y motors, their air generator H and water pump X, With this partition crossed by the axes S of the O and Y motors, axes Separate driving H and X, we avoid any danger of pro. water jets on the electric motors due to possible leaks from the pump X or the generator H in the event of upwelling in the latter.

The compartment 1 comprises the removable detachable dish N formed of a lower frame on which is fixed the compressed air distributor K. This latter is, for example and among others constituted by a hollow half-cylinder closed at its two extremities and provided with small tubes, said mouths V, allowing the outlet by these mouths of the air that H blows by J under and inside K. At these mouths V are fixed metal or other son whose tuft will rub the interior of the utensils which will be placed on V, this friction taking place under the turbulent agitation of the water produced by the air escaping under pressure of V. These mouths V may be constituted by ultrasonic whistles, or sonic or infra-sonic, fig. 6-7 and 8 for example, which will add their effect of vibratory waves to the water and to the air passing through V and actuating them.

The pots, pots and other similar utensils will cover the said mouths V by which is breathed into the water the air escaping from K under pressure which produces a violent agitation of the liquid which, in its ascent upwards, washes the rest dishes.

The N-holder is equipped with 4 vertical posts perforated with small pin holes. designed to adjust the height of the two plate-carrying frames to the size of the latter. On the uprights also slide glass holders, knife holders and fork holders whose current models are commercially available as drip trays.

The compartment 1 comprises a closure lid B with a peripheral rubber gasket under which is fixed by a central bolt a removable housing provided with a rain watering grate G 'which also serves as a filter screen for food waste. where appropriate. Said housing may be replaced by a sprinkler head, or by any sprinkler or by a hydraulic reaction sprinkler located under the cover B and connected by a pipe to the orifice D located on the cover B and intended to the fixing by screwing the pipe t 'water filling. Said housing has laterally an orifice 13 connected by the pipe t3 to the suction opening U (intake) of the air produced by the generator H. The latter thus sucks air which is introduced into the The duct t3 is surrounded by an insulated heating resistor not shown in the figure. Note that the lid B has a small angled tube which fits into the pipe t3 to allow the removal of the lid; this nesting does not have any consequence since the canalisation just sucks.

 Operation. - A pull rod c connects the stop valves RZ R 'and RI of the machine to wash the laundry located below. The zipper c is pulled out and at the same time these 3 shut-off valves are closed with a single movement. The stopcocks R6 and R 'of the dishwashing machine are also interconnected by an articulated rod terminated by a pulling eye d. In a single gesture by pulling the eyelet d itself opens the stopcocks R6 and R '. We put in the compartment 1 the amount of soap wanted as well as the dishware garnished plates, utensils and other washing. It is filled with water until a level of glazing locating whose window is set on the front of the machine washing the dishes. This filling is done by the pipe t 'screwed on D. It pushes on the housing b the button to start and stop the motor O. This last actuates the generator H which then blows, under the air distributor K the air sucked by the generator and the pipe t '. The generator blows through its exhaust tube J ', the duct t6 and JZ blowing tube opening J under the distributor K, insufflated, we say, its compressed air which by the mouths V will violently shake the compartment 1 water to wash.

Note here that the zippers <I> c and d </ I> do not have to be touched anymore and say, after draining (see below) the rinsing is only the reproduction of the washing operation with soap less.

Draining is effected by pressing the 2nd button of the housing b, button which switches on the pump X and its motor Y connected by the axis S passing through the partition of the intermediate compartment 2. The pump then sucks the water from the compartment 1 through the orifice 12 giving in this compartment by the duct t 'and the intake tube 11 of the pump which represses the liquid to be drained by its exhaust tube 10 and the hose t' hooked at a sink and finished with the tap R '.

The instructions which have just been described above are precisely those which exclude any possibility of staining the water of the dishwashing machine since this water is only drained by the pump without returning the species, in compartment 1.

To use, possibly, in addition to those actuated by the mouthpieces V of K ultra sounds, sounds or infrasons produced by the passage of water in whistles will be placed these fixed or adjustable frequencies, inside compartment 1 on an appropriate tube internally screwed on the orifice 14 which will unscrew the plug to screw in its place, the pipe F with the threaded portion of R '. By then making the pump work the whistles will come into action separately if one stops H and his engine or concomitantly with the air whistles of the mouths V if one also turns on the pressurized air generator and its engine.

<I> Drying. </ I> - When the oil is drained, the pressurized air generator is left running and the hot air, blown under K, will dry the dishes. It should be noted that in the dishwashing machine the distributor K can be omitted and that the air directly blown under pressure into the water by J is sufficient to stir the water of the compartment 1.

<I> Prewash. </ I> - Thanks to the grid G ', a prewash can be made in rain of continuous and renewed water; For this purpose the pipe will lead, without interruption, into the cover B and the compartment 1, the clean water of the local installation, water that the pump X starts, will evacuate by t2, to the sink, and in direct current of dirty water with food particles detached from the dishes. To save calories and water prewash, can, after filling, screw on one another, the free ends of t 'and t' whose tap R 'will of course be open, the pump being in march, the water of compartment 1 will circulate, then, in closed circuit without evacuation to the sink. On this occasion, the grid G 'will act as a filter screen for the residual food particles. It should be pointed out that this closed circuit is also capable of actuating a sparger, or a sprayhead or a hydraulic reaction turnstile in the case where, as mentioned above, one of these latter would be mounted instead. of the grid G '.

The machine can also be washed and rinsed by simply blowing air under pressure under K. In this case, when the pump X is stopped, the quantity of water in compartment 1 will not decrease and calories will be saved since instead of being drawn into the cold environment outside, the hot air compartment 1 will circulate in closed circuit, t 'being connected to t2 by R'.

The disadvantage of this means of economy is that if the pump is turned on the water saddle then circulates in the pump X where, during previous laundry operations, circulated l Dirty water from this laundry. Anyway, and for simplicity, it is preferable to connect the orifice 10 to the orifice 14 by a small fixed pipe with a stop and opening valve R ', as worn on fig. n 2. This faucet can also be articulated on the zipper d and be controlled by the latter. Under these conditions, the drain pipe t 'will no longer be screwed on 14 and occupy the place that is his in fig. n 2.

Another simplification will be to adopt, for valve heads, toothed knobs whose teeth mesh with a common control rod forming rack (or worm) and actuating the openings and closures of these valves using a one and the same gesture.

Instead, to use multiple robotic nets a sensible economy will be achieved by employing 3 small mobile hoses (rubber). The first one will be fixed in 11, the 2 'on J' and the 3 'on 10. This way, the free ends of these 3 small pipes will be able, by threaded ends, to be manually and respectively screwed in 12, in J = and in 14 for the use of the dishwasher, while they can be screwed respectively on 9 (as well as on t '), on t8 and on t' (and on t2), for the use of the dishwasher. For spinning, the second small pipe (the central one) will be unscrewed from it and screwed on T. <I> Washing machine </ I> (Fig. 1 and 2) Fig. 1 is a vertical section showing the components, organs and means described below with their operation. Fig. 2 represents a lateral external view showing the relative locations, enlarged for the comprehension, valves, pipes and ports for admission, exhaust, etc.

<I> Operation </ I> - Connect the filling hose t 'to the orifice W. Close the valves R', R6, R ', R9 and R4, the latter reserved for spinning.

The valves Rz, R ', W and possibly R8 are opened by simply pulling on the common pull c. The laundry is introduced into the compartment 3 with soap through an appropriate window. This port, located on the front of the compartment 3 will be sealed by a closure of the kind of pressure cookers, or others. The laundry to be washed then on the grid 'G', removable grid placed on the lower compartment 4. The water is filled by the pipe t 'to a marked mark on the window pane. The engines of the pressurized air generator H and the pump are started. X. The generator H then blows air through the tube J ', through the pipes t6 and te, then through the tube J' and finally through the threaded outlet orifice J4 which opens, under the laundry, into the 3. The air under pressure, thus insufflated, violently agitates the water and the linen and escapes by W and t '. For its part, the pump sucks, through the orifice 9, the pipe t 'and the suction tube 11, the amount of water and foam passed over the grid Gz. This water mixed with foam is then discharged by the pump, the tube 10 and the pipe t 'to the orifice L placed in the lowest part of the compartment 3, the valve R' of the pipe emptying t2 is well understood closed. The pressurized water is thus introduced by L and 1 into the compartment 4 from which it leaves, still under pressure, through the holes of the grid G3 which distributes it in ascending threads in the compartment 3. These nets facilitate the the air is blown in by J "and the whole agitates violently the water and projects the linen against the grid Gz where it is thus washed by shocks and friction.

It should be noted that the air blown by H originates from the outside but has been heated in the duct t 'embedded in its heating resistor. The exhaust of the air is outside by the orifice W and by t 'which is connected to it. For its part, the compartment 3 is heated by the gas ramp M (or by a heating resistor).

<I> Optional vibrating waves </ I>. If one wants to improve the system, one will screw, on the one hand, on J ^ one of the distributors K of fig. 3-4-5 and secondly, at the outlet of the tube 1 in the compartment 4 is screwed a horizontal tube bent or T-shaped closed at its or its free ends and perforated with holes. These splitters will print rhythmic pulsations with water. It will be possible, opul tively, to screw in these holes whistles with fixed or adjustable frequencies producing ultrasounds, sounds and infrasons according to the nature of the whistles adopted. The same will be done in the air outlet holes of the splitters K or directly on the orifice J4 for the models having no splitters K. Vibration waves will thus be obtained in the compartment 3 at the air passage and the passage of water in the whistles and this concomitantly or separately, to choose.

<I> Pulsed air. </ I> - The rhythmic pulsations mentioned above will recur cyclically thanks to the air distributors in fig. 3-4 and 5. These splitters produce pulsations of water because the air blown by J 'wins the upper part of K that caps J4. By accumulating at the top of the tundish the air compresses more and more and lowers the water level inside K until it reaches the exhaust holes in the lower belt. of the dispatcher. Part of the air emptied into the latter then escapes abruptly through the exhaust holes and the other part suddenly and partially decompressed back (from below K which is open), the level of the water well above the escape holes through which the water in turn penetrates into K where it also penetrates below K.

The <I> cycle </ I> just described is repeated as long as the pressurized air generator is running and prints, by said means, pulsations with water and laundry compartment 3. In the latter, the grid GZ may consist solely of a single grid in one or two pieces, for example with a median rubber band. Fig. 1 shows these two pieces formed by the two halves of GZ perforated many holes and interconnected by a strip of rubber while other rubber bands securing them to the side walls of the compartment 3. This does not exclude other fastening means by strand sandours or others for example.

 Drain. <I> - </ I> In order to drain, the valve RI is closed and, with R8 open, the pump that is turned on operates the drain, thanks in part to the ducting t 'and, on the other hand, to the drain hose. drain t2. The emptying may, without the aid of the pump, also be effected by blowing air which will drive water from compartment 3 before it.

 Rinsing. - Fill with clean water and start the pump. The flushing water is automatically discharged into direct current through the drain hose attached to the sink and this as the intake of clean water by t '. If we want to save the amount of water for rinsing, we can proceed to the latter closed circuit valve R 'being screwed to the end of t'. It should be noted that the rinsing operations must be carried out with the compressed air generator H running and causing the agitation of the water and the laundry to be rinsed by its blowing.

<I> Spin. </ I> - After draining, close RZ and open R 'which has a valve-valve of safe tee. The generator H is turned on and blows its compressed air by T into the rubber bladder Z (under and to which is fixed a min sheet that preserves punctures). This bladder, when gliding, pushes GI by stretching the rubber bands of the grid. The two halves of the latter then curl down and press the laundry on the grid G 'and on the bottom of the compar, timent 3. The expressed water of the linen goes from to much more easily, then, in the compartment 4 through the holes of the grid G ', that the pump X starts sucks under this grid water expelled from the laundry and establishes a depression in the compartment 4. This mode of spinning by bladder is more effective than that which consists, as for the emptying, to spin by simply blowing air from the compartment 3 the water being pierced or expressed laundry as the latter is sitting on the grid G '.

<I> drying. The laundry is spread in the compartment 3 and is dried there by blowing the air of the generator H turned on. To activate the drying, compartment 3 will be slightly warmed by switching on the gas ramp M (or the heating resistor which can replace this ramp).

<I> Simplifications of </ I> manczuvres. The numerous valve maneuvers described in the above-mentioned body of this patent have been detailed only to make the compositions of the air and water circuits of the machine comprehensible. In the reality of things, said maneuvers instead of being successively carried out by hand will be by pulling the hand or pushing or rotating the latter com-mandant either a zipper, a rack or a worm common as explained above; unless one prefers to use the three small hoses connecting, by fall and manually, either on the washing machine the saddle or on the washing machine as already indicated above.

<I> Machines </ I> jarxtaposed. <I> - </ I> The two machines object of the present instead of being superimposed as for the model described so far, can be, soli darily, juxtaposed with for elements and means constituting all or part of those who have been previously indicated. The surface economy characteristic realized by the means of the superposition will be, then, lost in the juxta position which admits such variants of forms or combinations as possible. Amongst other possible improvements, soft metal wires or puffs of nylon strands in front of those which will eventually fill, the mouthpieces V of K will be fixed on the walls of compartment 1. These additional wires are intended for turbulent agitation. water due to air insufflation, to rub the outside of pots or other capping mouths V.

Among the possible forms of the juxtaposed machines is a cylinder constituting, within a rectangular shaped casing, the inner body of the washing machine. In this case, the grid G 'will be round and the compartment 4 may be constituted by a sieve bowl which will serve as a pulsating distributor.

Among the multiple combinations falling within the scope of this patent are, among others, those consisting of: constituting X by two pumps placed one after the other, in series and stitched on the same common axis S. These two pumps (centrifugal or otherwise) would each have their own suction tubes 11 and exhaust 10. They would serve, one washing machine and the other washing machine the saddle. This combination allows, in each of the two machines, the use of water circulation in closed circuits without the water circulating in the dishwashing machine having to go through an organ where dirty water would have circulated. laundry. This assembly makes it possible, at the cost of slight modifications of the water pipes, to remove the drawbars <I> c and d </ I> f, - ,. 2 and the valves R ', R', RZ and RI and to make independent the channels of escape and suction of water of each of the two machines. The two pumps then work together, one full and the other empty. To avoid this minor inconvenience, the engine Y may be an inverter motor and both pumps may each be provided with one of the known freewheel systems. These two freewheels will be mounted in opposite directions on the axis S. All this makes it possible to use only a common motor Y but does not prevent, of course, having in the intermediate compartment 2 two separate pumps. driven by two separate electric motors.

Another combination is to delete, the distributors K of fig. 4 and 5 the air escape holes. This suppression would in no way affect the rhythmic pulsations that the air, escaping below the splitters, would print, still, with the water, but one would not have any more holes of fixing on distributor, whistles with vibra produced by air.

Another combination is, if one does not use pulsating splitters K, to provide J and J 'air whistles comparable to those of fig. 6 and 7, but placed in a circle or in continuous circumference on a closure plug screwed on J and on J .; This cap will be surrounded by a funnel (flag) directed upwards and serving mega phone amplifying, reflecting and upward the vibratory waves produced by the step, wise of the air of J and J in the whistles.

It should be further noted that the bent or T-shaped tube referred to above for the production of vibrating waves by water may, instead of having whistles screwed into suitable holes, be split over its entire upper length and receive in this slot a single whistle (FIG 6 or 7) extending, by welding, on and in the entire horizontal length of said slot.

 It is possible to provide said tube with a V-shaped vibratory reflector for example.

Claims (1)

 SUMMARY 1 One dishwashing machine and one washing machine are placed on one intermediate compartment and the other on the bottom. These machines can be superimposed or juxtaposed. Both use a common pump and compressed air generator placed in the intermediate compartment. The pump ensures the emptying and, in open or closed circuit, a flow of ash or ascending water. Through channels, in open circuit the water is, as and when, drained and, in a closed circuit, the water passes and passes through a grid in ascending nets concurrent with the blown air to agitate water and spray the laundry against a grid above the previous one. An inflatable bladder and a grid pushed back by the bladder drain the laundry whose water expressed by pressure is emptied by a channel opening into a lower compartment. , 2 The air generator provides insufflation, in both machines. This insufflation agitates the water and washes the laundry or the dishes according to whether one opens or closes ad hoc taps actuated in common by drawbars or worm. 3 Whistles screwed on water and air distributors, possibly, can add the action of ultrasonic or sonic or infra-sonic waves following the setting of these whistles. 4 Admissions and exhausts from the pump and generator may be manually connected or mechanically connected by taps to either the dishwashing machine or the following washing machine. The machine accepts various combinations such as two separate pumps operated by a single motor with or without a reversing switch and freewheel system. 6 The machine can use pulsating air distributors.
