Description

IMPROVEMENTS IN WASHING MACHINES CLOTHING DRYERS " This report refers to an Invention Patent that deals with improvements introduced in clothes washers and dryers, improvements that are essentially characterized by the fact that two new types of electric motors are introduced in the construction of said equipment.

It is the knowledge of the technique clothes washing machines in general, also called clothes washers, are characterized by accelerating the process of washing clothes through the attrition created by the resulting movement inside the washing chamber (basket) .

There are countless washing machines and washing systems in the market, in general, it has two representative systems, among them: by turning and by agitation.

In its basic configuration conventional washing machines use water or water vapor (which is considered universal solvent) and a chemical agent, considered a facilitator for the detachment of dirt, such as soap powder among others.

In the aforementioned wash washing system, the clothes are placed inside the washing chamber (basket), arranged horizontally, which receives the circular movement of the motor by means of a belt and pulley, and goes on to rotate 360 ° around an axis, the set of water, clothes and chemical agent accompanies the circular movement of the drum until it reaches the top of it, after which it falls, pushing down by force of gravity promoting the collision and the attrition of the set water and clothes with the surface of the basket, causing therefore the detachment of the dirt.

According to this conception, the clothing is not totally submerged, in this way needing a smaller amount of water compared to washing by agitation, where the clothes are totally submerged, the access to the clothes is made by the front part of the machine (top ) forcing the consumer to get off, thus representing an ergonomic problem.

In some machines that perform the washing by turning, the water is replaced by water vapor (dry cleaning) and the soap powder is replaced by other chemical agents (products), among them the percloretilene, Dry Par, Acqua Clean. In the washing by agitation, the set of water, clothes and chemical agent contained inside the basket, moves induced by the alternate horizontal movement of the finned shaft located in the center of the basket itself.

Thus, the alternate movement of the respective finned shaft inside the basket represents the element responsible for the friction between the water and the clothes, and consequently the detachment of the dirt, however the direct contact between the finned shaft and the clothes diminish the useful life of the tissues.

In this conception, the clothes are completely submerged, contributing to a comparatively large water consumption, in addition to the fact that the motor must be constantly demanded to promote the alternate horizontal movement of the finned shaft, thus increasing the amperage and consequently the consumption of electrical energy, in this system access to clothing (cover) is made by the upper part of the machine guaranteeing better ergonomics.

In the machines by agitation, the concentration of clothes in the inferior and superior part of the washing chamber remains almost unaltered thus providing a differentiated wash.

In parallel with conventional dryers the generally horizontal cylindrical baskets rotate 360 ° around an axis with a fixed speed together with the clothes that fall after reaching the top of the drum. Simultaneously to that movement hot air is introduced into the basket, through a fan positioned in the rear, upper or lower part of said basket, which causes the passage of air through a hot electrical resistance. Once hot, the air circulates naturally throughout the basket and consequently on the surface of the clothes, drying them.

The motors in the clothes dryers only execute the task of turning the drum in a constant low speed, around 50 RPM, in the washing machines the baskets turn in two speeds, one to wash and another to centrifuge, for it they need motors different This is the basic configuration of the two most representative systems of washers and dryers.

In the previous patent application of the same request, PI-9806475-4, the turning of the spherical drum was made in two directions simultaneously and for this, prior to the use of two motors, one to execute the 360 ° rotation around a "X" axis, and the other to execute the 360 ° rotation around a "Y" axis, being, in this case, using the surface of the washing drum itself to fix in it an integral part of the second motor; in this way, we had this second motor composed of a belt or ring of induced or induced by plastic, and fixed on the midpoint of the surface of the drum to isolate the current; the other part of the motor composed of another ring of armatures or inductors isolated from the contact of the water was coupled to the internal surface of the supporting arch, which involved the entire drum and consequently the ring or belt of armatures or inductors at its midpoint; In this way, the integrating elements of an electric motor were obtained, which are inductive and inductor, and an electrical current was induced to this set, in order to generate a magnetic field that executed the 360 ° rotation, around the second axis.

This being the case, a series of technical and operational advantages were obtained in relation to conventional clothes washers.

Following his studies and research on the matter, the Requeriente now developed some other forms and variations of the innovative electric motor and their respective applications.

The present patent substantially alters the concept of conventional clothes washers and dryers, since it envisages the application of the innovative concept of annular motor (circumscribed) and now also annular (flat) and its respective variations, in mini-washers and mini- clothes dryers more compact than the current ones. The circumscribed annular motor and the plane, plastically encapsulated and protected from water contact applied directly or indirectly on the surface of the drum or of the basket, substitutes considerably several usual mechanical components necessary to the movement of the washing basket as, belts, pulleys, gears , change generating with it new advantages.

Among them is the optimization of the washing process with consequent savings in water, space and electric power, once the washing process is done in a compact machine with smaller dimensions than the current ones that wash an average of 5 Kg., And spend approximately 240 liters of water in its total cycle.

Another advantage of constructive character consists of the application of the referred concept of electric motor to the concept of compact machine or mini-washer / mini-dryer, in this way, facilitating its construction, balancing, as well as simplifying its use.

Another advantage with respect to the fact of being able to couple part of the annular motor on the surface of the drum, of the basket, of the cover, of the finned shaft, or on the external lower part of the drum, generating directly or indirectly without the help of secondary parts. circular or alternate movement of the washing chamber (basket). We thus have an optimization of the components and consequent compaction of the machine.

The union of the concepts of compact machine and circumscribed annular motor or flat annular motor (with flat actuating sides overturned to each other) can be applied to the agitation system (vertical cylindrical drums) and to the tipping system (horizontal cylindrical drums) only now with reduced dimensions and with specific internal anatomy that occasionally substitutes the finned shaft.

Another advantage is the possibility of coupling on the surface of the access cover the clothing, part of this motor (stator) while the other part (rotor) can be coupled on the surface of the basket, thus understanding that by opening the door The machine automatically separates the rotor from the stator, turning it off, thus expanding the use and application of the concept.

Another advantage is the fact that the basket can optionally be removed at the end of the washing process and serve to transport the laundry.

Another advantage is related to the fact that we can have the annular electric motor as an autonomous component and independent of the basket and drum set of clothes and that therefore, it can be coupled circumstantially to execute specific tasks in drums with various dimensions, suitable for the amount of clothes.

A further advantage refers to the fact that the annular motor can have its independent parts, that is to say, rotor and stator, encapsulated by plastic guaranteeing thus the closure against water, and the isolation of the current, for this, it is foreseen at the moment of its manufacture the injection of the aforementioned parts in plastic or the use of ferrite (sintered) and subsequently polymerized.

The reduction of mechanical parts allows the expansion of the use of electronic components that add value and functionality to the washing machine.

It is necessary to differentiate the circumscribed annular motor from the other annular plane. The circumscribed annular motor has the basic components of a conventional motor, rotor (permanent magnets, electro-magnets or even esquilo cages) and stator (coil) only in this case, in an annular format, with one ring circumscribed to the other, it is say, a ring (rotor) with smaller diameter being involved in its entirety by another ring (stator) with larger diameter, or vice versa, being thus the elements of an electric motor are obtained, which are, inductor and induced and to that set plastically encapsulated, protected from the water contract, induces an electric current, so as to generate a magnetic field that thus drives the circular movement of the rotor around an axis.

The flat annular motor has the same components, rotor and stator of annular format, only now arranged in a parallel way, and with the acting sides of its rings turned towards itself, contrary to the previous one that has its rings one circumscribed to the other, being thus we have the rotor ring or disk with its permanent magnets positioned equidistantly and with its acting side turned towards the actuating side of the ring or winding stator disc, however in the two previous conceptions it is possible to replace the permanent magnets of the ring or rotor disk with a magnetic tape or "esquilo cage", thus adapting the construction of the engine to the implicit needs, whether by a synchronous or asynchronous motor.

In the synchronous motor is indicated the use of permanent magnets, because we have precise control of the RPM (rotation per minute) and speed, in the asynchronous motor where we have the known "slip", the control of the RPM and the speed are imprecise.

The annular format of the motor allows the arrangement of a greater number of permanent magnets on its surface and a greater number of poles, making the possibility of varying the high speeds to be reduced automatically, without the need for a mechanical speed reducer (change ).

The greater the number of poles and permanent magnets, the greater the possibility of speed reduction and the better the magnetic-magnetic properties of the magnets, the smaller the number of magnets required.

The use of natural or ferrite magnets (sintered) and polymerized in the rotor, naturally provides a protection against the action of water and dispenses posterior encapsulation, the use of neodymium magnets that are naturally more powerful, decreases the number of magnets needed if were compared with other less powerful.

Based on this, we can specifically use a brushless BDC type motor ("Brussless" construction) composed of a stator ring with three-phase winding of the type imbricated with 90 poles, involved by magnetic core (stator crown) without grooves ("tootless" construction ) and a rotor ring composed of 90 permanent magnets arranged parallel and equidistantly, supported by a magnetic conductor (rotor crown). The power supply of the stator windings is supplied by a "drive" with single-phase input of 220 Volts.

However, by altering the number of permanent magnets and consequently poles, a wide constructive variation is made possible, adapted to the needs without altering the original concept.

Therefore, in other possible variations, a BDC type motor without brushes is planned ("Brussless" construction) consisting of a stator ring with three-phase winding of the type imbricated with the "N" number of poles (suitable for the power and speed required) involved by magnetic core (stator crown) without grooves ("tootless" construction) and by a rotor ring, composed of an "N" number of permanent magnets arranged parallel and equidistantly, supported by a magnetic conducting arc (rotor ring).

The feeding and the control of the speed and rotation of the motor are supplied by an electronic device "Drive" that controls and establishes a low speed for the washing and another one higher for the centrifugation.

The application of part of the annular motor on the body of the drum and of the basket represents considerable advantage, since it is used of the surface of the object to be rotated to guarantee its assembly, however, the same components of the motor, that is to say, rotor and stator they do not work in isolation, therefore the assembly of the annular motor is also provided independently so that the distance and the alignment of its rings (rotor and stator) are kept unaltered and the motor effectively fulfills the corresponding motor function.

One of the forms of independent assembly consists of coupling the components of the motor, that is to say, rotor and stator respectively on the surface of two discs arranged in parallel; the first equipped with hole and central bearing, and the second equipped with actuator shaft coupled in its center, axis which fits and passes through the hole and the bearing of the first disc, thus keeping the assembly armed and aligned.

Another way is to apply the components of the annular motor, that is, rotor and stator to the surface of the rings of a bearing with specific dimensions and properties, thus transforming the simple bearing into an "annular motor bearing", that is, a bearing that has in his body an electric motor coupled.

Conventional bearings have as basic configuration an internal and an external ring, and between them one or two tracks of spheres or runners that guarantee concentricity, assembly and independent movement of the rings.

This set of innovations comes to simplify the construction of the machines, decreasing the number of component parts, as well as effectively making the viability of the new concept more concrete.

On the other hand, this set of innovations also applies to washing machines and dryers of conventional design of simple turning (horizontal cylindrical drums) and agitation (vertical cylindrical drums). With the application of the innovations now developed, in the aforementioned conventional machines, these become more compact, lighter, and substantially simpler, constructively and operatively.

Figure 11, in the same way as in figure 8, illustrates the independent assembly of the annular motor, only now in its planar annular configuration, ie flat annular motor 6, as a part, that is to say, with the stator ring 9. , armed on the side of a disk 11, which has at its center a hole 12, which disc runs parallel in its entirety the rotor ring 7, which rotor is coupled on the side of another disk 13, disc which transmits the circular or alternate movement of the rotor 7, through an axis 14, positioned in the center of the disk 13, which passes through the central hole 12, of the disk 11, which hole, in turn, receives the bearing 15 that involves and supports said shaft 14, thereby ensuring the movement of the rotor ring 7, as well as the assembly and alignment of the whole assembly.

The innovations coming from the use of the annular motor allow operative advantages, and among them the possibility of being able to use the own surface of the basket and the drum to fix in it part of the annular motor.

The object of the present patent refers to "Perfections Introduced in Clothes Washers and Dryers", according to which to perform the circular or alternating movement of the washing basket in the said system by agitation with vertical cylindrical drum, an engine is provided circumscribed annular 1, encapsulated, with part, that is to say, the stator ring 4, supported on the external lower surface of the water containment chamber (drum) 19, circumscribing in its entirety the rotor ring 2, which in turn , is coupled on the surface of a disc 13, and transmits the circular and alternating circular movement of the rotor 2, to the perforated washing chamber (basket) 20, which contains the clothes, through a central axis 14, positioned in the center of the disc 13, which passes the aforementioned drum 19, and touches the basket 20, thus causing its circular or alternate movement and allowing that at the end of the washing process the aforementioned basket 20 can be withdrawn. onally (according to figure 12).

In order to make the alternating circular movement of basket 20 in the system by agitation, in a more simplified way, we developed some other forms. One of them consists of using the upper real surface of the drum 19 to fix in it an integral part of the circumscribed annular motor 1, that is to say, the stator 4, duly encapsulated and protected from water contact; and the other part of the motor, composed of the rotor 2, also encapsulated plastically, is coupled to the upper surface of the basket 20, being involved in its entirety by the stator ring 4, being thus obtained the integral elements of an engine electrical, which are, rotor and stator that executes the alternating circular movement of the basket and at the end of the washing process allows the basket to be optionally removed and used to transport the clothes in conjunction with the rotor 2 (according to figure 13) .

Figure 14 illustrates another advantage that says with respect to the possibility of coupling on the surface of lid 21, of the clothes washer, part of this encapsulated circumscribed annular motor 1, that is, stator 4, while the other part, rotor 2 encapsulated, can be coupled on the surface of the basket 20, thus enabling the circular and alternate movement of the referred basket 20, thus expanding the use and application of the concept in the system said by agitation, but highlighting the importance of keep the distance and the alignment of the rotor 2 unchanged, in relation to the stator 4.

Additionally, we can apply the innovative concepts illustrated above in the vertical cylindrical drum agitation system to the system said by turning, with horizontal cylindrical drum.

Thus, in FIG. 15, a circumscribed annular motor 1 is provided, with part, that is to say, the stator ring 4 supported on the external rear surface of the drum 19, circumscribing in its entirety the rotor ring 2, which in turn it is coupled on the surface of a disk 13, and transmits the circular or alternating circular movement of the rotor 2, to the basket 20, through an axis 14, positioned in the center of the disk 13, which passes said drum 19, and touches the basket 20, thus causing circular or alternate circular movement and allowing that at the end of the washing process the aforementioned basket can be optionally removed.

In order to make the alternating circular or circular movement of the basket 20 in the system by turning it, in a more simplified way, we develop some other forms. One of them consists in using the actual front surface of the drum 19 to fix in it an integral part of the circumscribed motor 1, that is, stator 4, properly encapsulated and protected from contact with water; the other part of the motor, composed of the rotor 2, encapsulated plastically and isolated from the water contact, is coupled to the front surface of the basket 20, being completely circumscribed by the stator ring 4, thus obtaining the elements components of an electric motor, which are, rotor and stator that executes the circular or alternating circular movement of the basket and at the end of the washing process allows the drum to be optionally removed, and used to transport the clothes in conjunction with the rotor 2 (according to figure 16).

Figure 17 illustrates another advantage that says with respect to the possibility of coupling on the surface of lid 21, of the clothes washer, part of this circumscribed annular motor 1 encapsulated, composed of stator 4, while the other part composed of rotor 2 can be coupled on the surface of the basket 20, thus enabling its alternating circular or circular movement, extending from? that way the use and application of the concept in the system said by turning.

In the same way, the application of the now annular motor 6 is envisaged, in the six alternatives illustrated above in figures 12, 13, 14, 15, 16, 17, considering, however, the difference in design and layout of the rotor in relation to the stator, which now has the acting sides of its rings or discs parallel and turned towards itself, in contrast to the circumscribed annular motor, where the rotor ring is circumscribed to the stator ring or vice versa, as illustrated in figures 18, 19 , 20, 21, 22, 23.

In figure 18, in the same way as in figure 12, access to the basket 20, is made by the upper part of the machine, the flat annular motor 6, encapsulated, has one of the parts, stator 9, integrated to the lower outer surface of the drum 19; and the other part, rotor 7, integrated to the surface of a disk 13, which transmits the alternating circular movement of the rotor 7, to the basket 20, through the axis 14, central actuator.

In figure 20, in the manner of figure 14, we have part of the flat annular motor 6, encapsulated stator 9, coupled on the surface of the cover 21, of the clothes washer, while the other part, that is to say, the encapsulated rotor 7, coupled on the surface of the basket 20, thus executing the circular and alternating movement of the aforementioned basket 20 In figure 21, in the same way as in figure 15, access to the basket 20, is made by the front of the machine, the flat annular motor 6, has part, encapsulated stator 9, coupled to the rear surface external drum 19; and the other part, rotor 7, coupled to the surface of a disk 13, which transmits the alternating circular movement of the rotor 7, to the basket 20, through an axis 14, central actuator.

In figure 22, to the example of figure 16, we have part of the encapsulated flat annular motor 6, that is, stator 9, coupled on the real front surface of the drum 19, and the other part of the motor, composed of the encapsulated rotor 7 , coupled to the front surface of the basket 20.

In figure 23 with horizontal cylindrical drums, as in figure 17, we have part of the flat annular motor 6, encapsulated stator 9, coupled on the surface of the clothing access cover 21, of the clothes washer, while the another part, that is to say, encapsulated rotor 7, coupled on the surface of the basket 20, thus executing the circular and alternating movement of said basket 20.

In addition and also thanks to the use of these innovations in the machines described above, another important application is obtained, which is: in the simple wash with inclined washing chamber, preferably around 45 °; this makes possible a better accommodation and a more homogeneous distribution of the clothes inside the basket, now tilted, in addition to uniting the ergonomic advantages of washing machines by agitation, where access to clothes is made by the upper part of the advantages of simple tumbling washing, as illustrated in figures 24, 25, 26, 27, 28, 29.

In Figure 24, in the same way as in Figure 12, access to the basket 20, is made by the upper part of the machine, only now inclined. The circumscribed annular motor 1 has one of the parts, stator 4, integrated to the outer lower surface of the drum 19; and the other part, rotor 2, integrated to the surface of a disk 13, which transmits the alternating circular movement of the rotor 2, of the basket 20, through an axis 14.

In figure 27, in the same way as in figure 18, access to the basket 20 is made by the inclined upper part of the machine, only now with the flat annular motor 6, which has one of the parts, stator 9, integrated to the outer bottom surface of the drum 19; and part, rotor 7, integrated to the surface of a disk 13, which transmits the circular or alternate movement of the rotor 7, to the basket 20, through an axis 14.

Already in FIG. 28, as in FIG. 19, it now shows part of the flat annular motor 6, that is, stator 9, coupled on the immovable upper surface of the drum 19, now inclined and the other part of the motor, composed of the rotor 7, coupled to the upper surface of the basket 20.

In figure 29, in the same way as in figure 20, we have part of the flat annular motor 6, stator 9, coupled on the surface of the lid 21, of the laundry machine now inclined, while the other rotor part 7 , coupled on the surface of the basket 20, thus executing the circular and alternating movement of said basket 20.

We can extend the application of circumscribed annular motor 1, and plane 6, in machines that wash by agitation with vertical drums, but now using a finned shaft, being this way the alternate movement of the respective finned shaft inside the drum represents the element responsible for the attrition between water and clothing, this attrition can be caused by a direct contact of the shaft with fins and the set of water and clothing, or indirect, if we have a shaft with smaller fins, separated from direct contact with clothing by intermediate of a cloth or perforated grid, in this case the finned shaft moves the water that, in turn, moves the clothes.

To make the alternating circular movement of the finned shaft 22, inside the basket 20, using the said system by agitation, a circumscribed annular motor 1 is provided, with part, that is, the stator ring 4, resting on the surface external lower part of the drum 19, and circumscribing in its entirety the rotor ring 2, which in turn is coupled on the surface of a disk 13, and transmits the circular or alternate movement of the rotor 2, to the finned shaft 22, to through a central actuator shaft 14, positioned in the center of the disc 13, which passes through the drum 19, and touches the finned shaft 22, at the moment of washing by rotating it, and which after decoupling the finned shaft 22, touches the basket on the occasion of centrifugation (according to figure 30).

To make the alternating circular motion of the finned shaft 22, inside the basket 20, using the said system by agitation, a flat annular motor 6 is provided, with part, that is, the stator ring 9, resting on the surface external lower part of the water containment chamber, drum 19, which tilts in its entirety the rotor ring 7, which in turn is coupled on the surface of a disk 13, and transmits the circular or alternate movement of the rotor 7, to the finned shaft 22, through a central drive shaft 14, positioned in the center of the disc 13, which passes through the drum 19, and touches the finned shaft 22, at the time of the washing making it turn, and that after decoupling the Shaft with fins 22, touches basket 20, for spinning (according to figure 31.).

Figure 33 illustrates the application of the flat annular motor 6, in the same way as in figure 31, only now with the finned shaft separated from the direct contact with the clothes, for this is provided, a flat annular motor 6, with part, that is to say, the stator ring 9, resting on the external lower surface of the water holding chamber, drum 19, which tilts in its entirety the rotor ring 7, which in turn is coupled on the surface of a disk 13, and transmits the circular or alternating movement of the rotor 7, to the finned shaft 22, separated from the direct contact with the clothing by a cloth or grid 23, through a central drive shaft 14, positioned in the center of the disk 13, which passes through the drum 19 and touches the finned shaft 22, at the moment of the washing making it turn, and that after uncoupling from the finned shaft 22, touches the basket 20, on the occasion of the spinning.

The improvements now envisaged can also be applied in mini clothes dryers, which in the manner of the mini-washers, eliminates or diminishes several mechanical components used in the transmission such as pulleys, belts, gears, as illustrated in figures 34, 35 , 36, 37, 38, 39.

In Figure 34, access to clothing is made through the front of the mini-dryer. The circumscribed annular motor 24, has one of the parts, stator 26, integrated to the outer rear surface of the drum 19; and another part, the rotor 25, integrated to the surface of a disk 13, which transmits the circular movement of the rotor 25, to the basket 20, through an actuator shaft 14.

Already in figure 35, we have part of the circumscribed annular motor 24, of the mini-dryer, that is, stator 26, coupled on the real front surface of the drum 19, and the other part of the motor composed of the rotor 25, coupled to the front surface of the basket 20.

In figure 36 we have part of the circumscribed annular motor 24, of the mini-dryer, that is to say, the stator 26, coupled on the surface of the access cover to the clothes 21, of the clothes dryer, while the other part , the rotor 25 is coupled on the surface of the basket 20, thus executing the circular and alternating movement of the mentioned basket 20.

Already in figure 38, as shown in figure 35, we now have part of the plane annular motor 27 of the mini-dryer, that is to say, the stator 29 coupled on the real front surface of the drum 19, and the other part of the motor composed of the rotor 28, coupled to the front surface of the basket 20.

In figure 39, as in the front figure real estate of the drum 19, and the other part of the engine, composed of the rotor 28, coupled to the front surface of the basket 20.

In figure 39, as in figure 36, we have part of the annular plane motor 27, the stator 29, coupled on the surface of the access cover to the clothes 21, of the dryer, while the other part, the rotor 28 , coupled on the surface of the basket 20, thus executing the circular movement of said basket 20.

Finally, the requester developed other variations that are related to the fact of completely separating the circumscribed and flat annular motor from the assembly composed of drum and basket, thus having the annular motor armed as an autonomous component, totally independent and now named agitator, responsible for the movement of the drum and basket, either to wash, spin or dry.

The basket and drum assembly may be coupled occasionally to said agitator for the execution of the intended task.

In this way we achieve some advantages, among them, the ability to attach varied drums with dimensions appropriate to the amount of clothing.

Another advantage of an operational nature consists in having completely separated the components responsible for the movement, in this case, the annular motor of the remaining set, basket and drum, thus allowing the aforementioned components to be accommodated, transported, manipulated and even acquired separately.

In summary, the agitator is the independent annular motor, composed of rotor and stator properly assembled and encapsulated, which transmits when it is fitted to the set intended, in the case, drum and basket, the circular movement of the rotor through a central axis.

Figure 40 illustrates the aforementioned agitator 30, composed of a circumscribed annular electric motor 1, with the stator ring 4, armed on the internal perimetric structure of a disk 31, having at its center a hole 32, which circumscribes in completely the rotor ring 2, rotor which is coupled on the external perimeter surface of a disk 33, which disc transmits the circular or alternate movement of the rotor 2, through an axis 34, positioned in the center of the disk 33, passing through the central hole 32, of the disc 31, hole which in turn has received bearing 35, which involves and supports the said axis 34, thus guaranteeing the movement coming from the rotor ring 2, as well as the assembly and alignment of all the set that, in turn, is closed by a lid 36.

Figure 41 shows the agitator assembly 37, now using the flat annular motor 6, with the stator ring 9, armed on the side of a disk 38, having at its center a hole 39, a disk which tilts parallel in its entirety the rotor ring 7, rotor which is coupled on the side of another disk 40, disc which transmits the circular or alternating movement of the rotor 7, through an axis 34, positioned in the center of the disc 40, axis which transfers the central hole 39, of the disc 38, hole which, in turn, has received bearing 35, which involves and supports said shaft 34, thus guaranteeing the movement coming from the ring (...) axis 34, positioned in the center of the disc 40, axis that passes through the central hole 39, of the disc 38, hole that, in turn, has received the bearing 35, which involves and supports the shaft 34, thus guaranteeing the movement coming from the rotor ring 7, as well as the assembly and the alignment of the whole set, which in turn is closed by a lid 36.

Figure 42 shows the agitator assembly 30, fully assembled and closed with its central axis 34.

Obviously these are only some schematic examples, it being clear that any alteration introduced in the present invention are included and protected by the present patent.
