CLOTHES WASHING AND DRYING MACHINES"
This report refers to an Invention Patent that addresses improvements introduced in clothes washing s machines and dryers. These improvements are essentially characterized b the fact that they introduce two new types of electric motors in the construction of the aforementioned equipment.
As known by the technical expert, clothes washing machines in general, also called washers, are io basically characterized by accelerating the clothes washing process by means of the friction created by the resulting movement inside the washing chamber (tub).
There is a wide variety of washing machines and washing systems on the market. Generally speaking, is there are two representative systems: washing by tumbling and by agitation.
In their basic configuration, conventional washing machines use water or water vapor (which is considered a universal solvent), and a chemical agent, considered a 2o facilitator for the loosening of dirt, such as soap powder, among others.
As mentioned above, in the washing system by tumbling, the clothing is placed inside the washing chamber (tub), which is arranged horizontally and receives the circular 2s movement of the motor through a belt and pulley and starts to revolve 360 around an axis. The water, clothing and chemical agent accompany the circular movement of the tub until they reach its upper part, after which the tub falls, forced downwards by the force of
2 gravity, promoting the collision and friction of the water and clothing with the surface of the basket, thus loosening of dirt.
According to this conception, the clothing is not totally submersed, hence less water is required than s with washing by agitation, where the clothing is totally submersed. In this type of machine the clothing is loaded from the front (door), obliging consumers to lean down, thus representing an ergonomic problem.
In some machines that wash by io tumbling, the water is substituted by water vapor (dry cleaning), and the soap powder by other chemical agents (products), including perchloretylene, Dry Part and Acqua Clean.
In washing by agitation, the movement of the water, clothing and chemical agent contained inside is the tub is induced by the alternate horizontal movement of the axis with blades located at the center of the actual tub.
Hence the alternate movement of the respective axis with blades inside the tub represents the element responsible for friction between the water and clothing, and 2o consequently for the loosening of dirt. However, the direct contact between the axis with blades and the clothing reduces the useful life of fabrics.
In this conception, the clothing is totally submersed, contributing towards a relatively high consumption 2s of water. Furthermore, the motor is constantly required to promote the alternate horizontal movement of the axis with blades, thus increasing the amperage and consequently the consumption of electric power. In this system the clothing is accessed from the top of the machine (lid),

Furthermore, the motor is constantly required to promote the alternate horizontal movement of the axis with blades, thus increasing the amperage and consequently the consumption of electric power. In this system the clothing is accessed from the top of the machine (lid),
3 thus guaranteeing better ergonomics.
In machines that operate by agitation, the concentration of clothing in the lower and upper part of the washing chamber remains almost unaltered, thus promoting a s differentiated kind of wash.
In parallel, with conventional dryers the tumblers, which are usually horizontal and cylindrical, rotate 360 around an axis together with the clothing at a fixed speed that decreases after the upper part of the tub is reached. Hot air is io simultaneously introduced in the tub from a fan positioned at the back, top or lower part of this tub, which provokes the flow of air by a heated element. Once heated, the air circulates naturally around the tub and consequently over the surface of the clothing, drying it.
Motors in clothes dryers only execute is the task of rotating the tank at a constant low speed of around 50 rpm;
in washing machines the tubs rotate at two speeds, one for washing and the other for spinning, hence they need different motors.
This is the basic configuration of the two most representative systems of clothes washing machines and 2o dryers.
In the prior patent application from the same applicant, PI-9306475-4, the tumbling of the spherical tub was executed in two directions simultaneously and for this purpose established the use of two motors, one to execute the 360° turn 2s around an "x" axis and the other to execute the 360 turn around a "Y"
axis. In this case, the actual surface of the washing tank was used to fix a part of the second motor; in this manner, a second motor was obtained, consisting of a belt or ring of induced or inductors covered

4 by plastic and fastened to the middle point of the surface of the tank to isolate the current; the other part of the motor, comprising another ring of induced or inductors sealed off from contact with water was coupled to the internal surface of the supporting arch, which covered s the entire tank, and consequently the ring or belt of induced or inductors at its middle point. Hence the elements that comprise an electric motor were obtained i.e., inductor and induced. An electric current was supplied to this assembly in order to generate a magnetic field that executed the 360° turn around the second axis.
to Thus a series of technical and operational advantages was obtained in comparison with conventional clothes washers.
Continuing with studies and research on the topic, the Applicant has now developed other forms and is variations of the innovative electric motor and its respective applications.
The purpose of this patent is to substantially alter the concept of conventional clothes washing and drying machines in order to provide for the application of the 2o innovative ring-motor concept (circumscribed) and now also of the flat ring-motor and respective variations, in mini clothes washing and drying machines that are more compact than current ones. The circumscribed and flat ring-motor, encapsulated with plastic and protected from contact with water applied directly or indirectly on the 2s surface of the tank or tub serves as an excellent substitute for various normal mechanic components necessary for the movement of the washing tub, such as belts, pulleys, gears and gearbox, thus generating new advantages.
These advantages include the optimization of the washing process, with consequent economy of water, space and electric power, since the washing process is executed in a compact machine with much smaller dimensions than s current ones, which on average wash 5 kg and consume around 240 liters of water in their total cycle.
Another advantage of a constructive nature consists of the application of the aforementioned electric motor concept to the compact machine or mini washer mini dryer concept, to thus facilitating their construction and balancing further to simplifying their use.
Another advantage refers to the fact that part of the ring-motor can be coupled on the surface of the tank, of the tub, of the lid, of the axis with blades or on the outside lower is part of the tank, generating the circular or alternate movement of the washing chamber (tub) directly or indirectly without the assistance of secondary parts. In this manner the components are optimized the machine is consequently compacted.
The combination of the compact 2o machine and circumscribed ring-motor or flat ring-motor (with flat active sides facing each other) concepts can be applied to the agitation system (vertical cylindrical tanks) and to the tumbling system (horizontal cylindrical tanks), only now with reduced dimensions and with a specific internal anatomy that occasionally substitutes the axis 2s with blades.
Another advantage is the possibility of coupling part of this motor (estator) on the surface of the machine door while the other part (rotor) can be coupled on the surface of the tub. Hence when the door of the machine is opened, the rotor is automatically separated from the stator, turning it off and expanding the use and application of the concept.
An additional advantage refers to the s fact that the tub can be optionally removed at the end of the washing process and serve to transport the clothing.
Another advantage is related to the fact that we can use the electric ring-motor as an autonomous and independent component of the clothes tub assembly, that can to therefore be coupled circumstantially to execute specific tasks, in tanks of varied dimensions suited to the quantity of clothing.
Yet another advantage refers to the fact that the parts of the ring-motor, i.e., rotor and stator, are independently encapsulated in plastic, thus guaranteeing sealing is against water and the insulation of the current. For this purpose when the aforementioned parts are manufactured they will be injected with plastic or ferrite (syntherized) and subsequently polymerized.
The reduction of mechanic parts allows for a wider range of uses of electronic components that add 2o value and functionality to the washing machine.
The circumscribed ring-motor must be differentiated from the flat ring- motor. The former type has the basic components of a conventional motor: rotor (permanent magnets, electromagnets or even a squirrel grid) and stator (coil), only in this 2s case in a ring format, with one ring circumscribed to the other, i.e., one ring (rotor) with a smaller diameter totally covered by another ring (stator) with a large diameter or vice versa, thus obtaining the elements that form an electric motor, i.e., inductor and induced. An electric current is induced to this plastically encapsulated assembly protected from contact with water to generate a magnetic field, which drives the circular movement of the rotor around an axis.
The flat ring-motor has the same s components: rotor and ring-stator, only arranged in parallel, with the active sides of their rings facing, contrary to the previous one whose rings are circumscribed. Hence the ring or rotor disc with its permanent magnets are positioned equidistantly and with their active side facing the active side of the ring or coiled stator disc.
to However, in the two previous designs, it is possible to substitute the permanent magnets of the ring or ,rotor disc with a magnetic belt or squirrel grid, thus adapting the construction of the motor to the implicit requirements, whether for a synchronous or asynchronous motor.
is The use of permanent magnets is indicated in synchronous motors as we have precise control of the RPM (rotation per minute) and of the speed. In asynchronous motors where "slipping" is a known feature, the RPM and speed control are imprecise.
2o The ring format of the motor permits the arrangement of a greater number of permanent magnets on its surface, and respectively, a greater number of poles, making for a wide range of variations from high to reduced speeds automatically, without the need for a mechanic speed reducer (gearbox).
as The larger the quantity of poles and permanent magnets the greater the speed reduction possibility, and the better the physical-magnetic properties of the magnets, the fewer magnets required.
The use of natural or polymerized ferrite (synthesized) magnets in the rotor naturally establishes protection against the action of water and does away with the need for subsequent encapsulation. The use of neodimeo magnets that are s naturally more powerful reduces the number of necessary magnets in comparison to other less powerful ones.
Based on this, we can specifically use a BDC type Brushless motor, consisting of a stator ring with an embricado type three phase bearing with 90 poles, covered by a io magnetic core (crown of the stator) without teeth, and a rotor ring consisting of 90 permanent magnets arranged in parallel and equidistantly, supported by a magnetic conductor (rotor crown). The stator bearings are supplied with power by an "drive", with a single phase 220V inlet.
is However, by altering the number of permanent magnets, and consequently poles an ample constructive variation is obtained, suited to needs without altering the original concept.
Hence in other possible variations 2o a BDC type Brushless motor is established, consisting of a stator ring with embricado type three phase bearing, with an "N" number of poles (suited to the necessary power and speed), covered by a toothless magnetic core (stator crown) and a rotor ring, consisting of an "N" number of permanent magnets arranged in 2s parallel and equidistantly, supported by a magnetic conductor arch (rotor ring).
The supply and control of the speed and rotation of the motor is executed by an electronic Drive device that controls and establishes a low speed for washing and a higher one for spinning.
The application of part of the ring-motor on the body of the tank and tub represents a considerable s advantage, since the surface of the object to be spun is used to guarantee its mounting. However, the same motor components, i.e., rotor and stator, do not operate separately, hence the patent establishes the assembly of the ring- motor independently, for the distance and alignment of its rings (rotor and stator) to be maintained to unaltered, and for the motor to effectively perform the function for which it is designed.
One of the forms of independent assembly consists of coupling the motor components, i.e., rotor and stator respectively, on the surface of two discs arranged in parallel;
is the first equipped with a hole and central bearing and the second equipped with an activating axis coupled at its center. This axis fits into and overreaches the hole and the bearing of the first disc, thus maintain the assembly mounted and aligned.
Another form is to apply the 2o components of the ring-motor, i.e., rotor and stator , to the surface of the rings of a bearing with specific dimensions and properties, thus transforming the simple bearing into a "ring-motor bearing", i.e., a bearing with a coupled electric motor in its body.
The basic configuration of 2s conventional bearings consists of an internal ring and another external ring, separated by one or two tracks of spheres or ring rollers that guarantee the concentricity, assembly and independent movement of the rings.
This set of innovations serve to simplify the construction of the machines, reducing the number of component parts and making the viability of the new concept effectively more concrete.
On the other hand, this set of innovations also applies to conventional simple tumbling washers and dryers (horizontal cylindrical tanks) and washers and dryers that operate by agitation (vertical cylindrical tanks). With the application of the innovations developed here in the aforementioned conventional io machines, these become more compact, lighter and substantially simpler, both in constructive and operational terms.

Figure 8 shows an independent form s of mounting the ring-motor, including a circumscribed ring-motor 1, with the stator ring 4, mounted on the internal perimeter structure of a disc 1 1 , with a hole 12 in its center. This disc totally circumscribes the rotor ring 2, a rotor which in turn is coupled on the external perimeter surface of another disc 13, which transmits the circular or alternate io movement of the rotor 2 through an axis 14, positioned in the center of the disc 13, which overreaches the central hole 12 of the disc 11. In turn, this hole has a fitted bearing 15, which surrounds and supports the axis 14, thus guaranteeing the movement of the rotor ring 2, further to the mounting and alignment of the assembly.
is Figure 9 shows a perspective view with a cross-section of another form of independent assembly on the surface of a bearing (R). For this purpose a circumscribed ring-motor 1 is provided for, in which the rotor ring 2 and the stator ring 4 are respectively coupled on the surface of the internal bearing rings 16 2o and external bearing 17 of a bearing (R). In this case the external surface of the internal bipartite bearing ring 16 is used to fix a part of the circumscribed ring-motor 1, i.e., the rotor 2, and on the internal surface of the external bearing ring 17 the other part of the circumscribed ring-motor 1, i.e., the stator 4, or vice versa, separated 2s by two tracks of spheres or ring rollers 18, which guarantee the concentricity, assembly and independent movement of the rings, with the advantage of having cleared the central space or core of the rings to fix the object to be rotated directly in this space.
Figure 10 highlights the detail of the mounting of the assembly described in figure 9, where the following components can be seen: rotor 2, stator 4, internal bearing ring 16 and external bearing ring 17 and track of spheres or ring rollers 18 of the s circumscribed motor 1.
Figure 11, in the same way as figure 8, illustrates the independent mounting of the ring-motor, only in its flat ring configuration, i.e., flat ring-motor 6, with part, i.e., with the stator ring 9 mounted on the front of a disc 11, which has a hole 12 in io its center. This entire disc faces the rotor ring 7 in parallel, and the rotor is coupled on the front of another disc 13, which transmits the circular or alternate movement of the rotor 7 through an axis 14, positioned in the center of the disc 13, which overreaches the central hole 12 of the disc 11. In turn, this hole has a fitted bearing 15, which is surrounds and supports the aforementioned part further to the mounting and alignment of the entire assembly.
The innovations arising from the use of the ring-motor permit operating advantages, including the possibility of using the actual surface of the basket and tank to fix part of the 2o ring-motor.
The subject matter of this patent refers to "Improvements Introduced to Clothes Washing and Drying Machines", according to which, to execute the circular or alternate movement of the washing tub in the so-called agitation system with a 2s vertical cylindrical tank, the following components are provided for: an encapsulated circumscribed ring-motor 1, with part, i.e., the stator ring 4, supported on the outside lower surface of the water containment tank (tank) 19, which entirely circumscribes the rotor ring 2, which in turn is coupled on the surface of a disc 13, and transmits the circular and alternate circular movement of the rotor 2, to the perforated washing chamber (tub) 20 containing the clothing, through a central axis 14, positioned in the center of the disc 13, which overreaches the s aforementioned tank 19, and touches the tub 20, thus causing its circular or alternate movement and permitting the optional removal of the aforementioned tub 20 at the end of the washing process (pursuant to figure 12).
To make the alternate circular io movement of the tub 20 in the agitation system in a more simplified manner, we have developed other forms. One of these consists of using the actual immobile top surface of the tank 19 to fix a part of the circumscribed ring- motor 1, i.e., the stator 4, properly encapsulated and protected from contact with water; and the other part of the motor, is consisting of the rotor 2, also encapsulated in plastic, coupled to the top surface of the tub 20 and totally covered by the stator ring 4, thus obtaining the elements of an electric motor, i.e.: rotor and stator that execute the alternate circular movement of the tub and at the end of the washing process permit the optional removal of ao the tub to transport the clothing, together with the rotor 2 (pursuant to figure 13).
Figure 14 illustrates another advantage concerning the possibility of coupling part of this encapsulated circumscribed ring-motor 1 on the surface of lid 21 of 2s the washing machine, i.e., stator 4, while the other part, the encapsulated rotor 2, can be coupled on the surface of the tub 20, permitting the circular and alternate movement of the aforementioned tub 20, thus expanding the use and application of the concept in the so-called agitation system, although emphasizing the importance of keeping the distance and alignment of the rotor 2 in relation to the stator 4, unaltered.
In addition, we can apply the s innovative concepts illustrated above in the agitation system with vertical cylindrical tub to the so-called tumbling system with a horizontal cylindrical tub.
Hence figure 15 illustrates a circumscribed ring-motor 1, with part, i.e., the stator ring 4, supported to on the outside posterior surface of the tank 19, which totally circumscribes the rotor ring 2, which in turn is coupled on the surface of a disc 13, and transmits the circular or alternate circular movement of the rotor 2, to the tub 20, through an axis 14 positioned in the center of the disc 13, which overreaches the aforementioned tank 19, is and touches the tub 20, thus causing the circular or alternate circular movement and permitting the optional removal of the aforementioned tub at the end of the washing process.
To executed the circular or alternate circular movement of the tub 20 in the tumbling system in a more 2o simplified manner, we have developed some other forms. One of these consists of using the actual immobile front surface of the tank 19, to fix a part of the circumscribed ring-motor 1, i.e., the stator 4, properly encapsulated and protected from contact with water; and the other part of the motor, consisting of the rotor 2, also encapsulated in 2s plastic and protected against contact with water, coupled to the front surface of the tub 20, totally circumscribed by the stator ring 4, thus obtaining the elements of an electric motor, i.e. rotor and stator that execute the circular or alternate circular movement of the tub and at the end of the washing process, permit the optional removal of the tank for use to transport the clothing, together with the rotor 2 (pursuant to figure 16).
Figure 17 illustrates another s advantage related to the possibility of coupling part of this encapsulated circumscribed ring-motor 1 on the surface of the lid 21 of the clothes machine, comprising a stator 4, while the other part consisting of a rotor 2 can be coupled on the surface of the tub 20, thus permitting its circular or alternate circular movement and to expanding the use and application of the concept in the so-called tumbling system.
Likewise the application of the flat ring-motor 6 is established in the six alternatives previously illustrated in figures 12, 13, 14, 15, 16 and 17, although considering the is difference in the design and arrangement of the rotor in relation to the stator, with the active sides of its rings or discs parallel and facing each other, contrary to the circumscribed ring-motor where the rotor ring is circumscribed to the stator ring or vice versa, as illustrated by figures 18, 19, 20, 21, 22 and 23.
2o In figure 18, as in figure 12, access to the tub 20 is made from the top of the machine, one of the parts of the encapsulated flat ring-motor 6, the stator 9, is integrated to the outside lower surface of the tank 19; and the other part, the rotor 7, is integrated to the surface of a disc 13, which transmits the alternate 2s circular movement of the rotor 7 to the tub 20 through the axis 14, central driver.
In figure 19, as in figure 13, part of the encapsulated flat ring-motor 6, i.e., the stator 9, is coupled on the immobile top surface of the tank 19, and the other part of the motor, consisting of the encapsulated rotor 7, is coupled to the upper surface of the tub 20.
In figure 20, as in figure 14, part of s the flat ring-motor 6, the stator 9, is encapsulated, coupled on fihe surface of the lid 21 of the washing machine, while the other part, i.e., the encapsulated rotor 7, is coupled on the surface of the tub 20, thus executing the circular and alternate movement of the aforementioned tub 20. In figure 21, as in figure 15, access to the tub 20 is made from io the front of the machine, and part of the flat ring-motor 6, the encapsulated stator 9, is coupled to the outside posterior surface of the tank 19; while another part, the rotor 7, is coupled to the surface of a disc 13, which transmits the alternate circular movement of the rotor 7 to the tub 20 through an axis 14, central driver.
is Ln figure 22, as in figure 16, part of the encapsulated flat ring-motor 6, i.e. the stator 9, is coupled on the immobile front surface of the tank 19, and the other part of the motor, consisting of the encapsulated rotor 7, is coupled to the front surface of the tub 20.
2o In figure 23 with horizontal cylindrical tanks, as in figure 17, part of the flat ring-motor 6, the encapsulated stator 9, is coupled on the surface of the clothing access lid 21 of the washing machine, while the other part, i.e., the encapsulated rotor 7, is coupled on the surface of the tub 2s 20, thus executing the circular and alternate movement of this tub 20.
Furthermore, and also thanks to the use of these innovations in the machines describe above, another highly important application is obtained: in simple tumbling with a tilted washing chamber, preferably at around 451; this promotes an improved accommodation and a more homogeneous distribution of clothing inside the tub, which is now tilted, besides combining the s ergonomic advantages of machines that wash by agitation, where access to the clothing is made from the top of the machine, with the advantages of washing by simple tumbling, as illustrated by figures 24, 25, 26, 27, 28 and 29.
In figure 24, as in figure 12, access to to the tub 20 is made at the top of the machine, which is tilted. One of the parts of the circumscribed ring-motor 1, the stator 4, is integrated to the outside top surface of the tank 19; and the other part, the rotor 2, is integrated to the surface of a disc 13, which transmits the alternate circular movement of the rotor 2 to the tub 20 through an is axis 14.
In figure 25, as in figure 13, part of the circumscribed ring-motor 1, i.e., the stator 4, is coupled on the immobile upper surface of the tank 19, now tilted, and the other part of the motor, consisting of the rotor 2, is coupled to the top surface of 2o the tub 20.
In figure 26, as in figure 14, part of the circumscribed ring-motor 1, i.e., the stator 4, is coupled on the surface of the lid 21 of the washing machine, now tilted, while the other part (rotor 2) is coupled on the surface of the tub 20, thus 2s executing the circular and alternate movement of this tub 20.
In figure 27, as in figure 18, access to the tub 20 is made via the tilted top part of the machine, only with the flat ring-motor 6, with one of its parts, the stator 9, integrated to the outside lower surface of the tank 19; and another part, the rotor 7, integrated to the surface of a disc 13, which transmits the circular or alternate movement of the rotor 7 to the tub 20 through an axis 14.
Figure 28, like figure 19, now shows s part of the flat ring-motor 6, i.e., the stator 9, coupled on the immobile top surface of the tank 19, now tilted, and the other part of the motor, consisting of the rotor 7, coupled to the top surface of the tub 20.
In figure 29, as in figure 20, part of the flat ring-motor 6, the stator 9, is coupled on the surface of the lid io 21 of the now tilted washing machine, while the other part (rotor 7) is coupled on the surface of the tub 20, thus executing the circular and alternate movement of this tub 20.
We can extend the application of the circumscribed ring-motor 1, and of the flat motor 6, in machines that is wash by agitation with vertical tanks, although using an axis with blades. Hence the alternate movement of the respective axis with blades inside the tank represents the element responsible for friction between the water and the clothing. This friction can be caused by direct contact of the axis with blades and the water and clothing, or by 2o indirect contact, if we have a smaller axis with blades separated from direct contact with the clothing by a screen or perforated grid, in this case the axis with blades moves the water which in turn moves the clothing.
To execute the alternate circular 2s movement of the axis with blades 22 inside the tub 20 using the so-called agitation system, a circumscribed ring-motor 1 is established with part, i.e., the stator ring 4, supported on the outside bottom surface of the tank 19, which circumscribes the entire rotor ring 2, which in turn is coupled on the surface of a disc 13, and transmits the circular or alternate movement of the rotor 2 to the axis with blades 22, through a central driving axis 14, positioned in the center of the disc 13, which overreaches the tank 19, and touches the axis with s blades 22 during the washing cycle, making it rotate, and that after being uncoupled from the axis with blades 22, touches the tub during the spinning cycle (pursuant to figure 30).
To execute the alternate circular movement of the axis with blades 22 inside the tub 20, using the so-lo called agitation system, a flat ring-motor 1 is established with part, i.e.
the stator ring 9, supported on the outside bottom surface of the water contention tank, tank 19, which completely faces the rotor ring 7, which in turn is coupled on the surface of a disc 13, and transmits the circular or alternate movement of the rotor 7 to the axis with blades is 22, through a central driving axis 14, positioned in the center of the disc 13, which overreaches the tank 19, and touches the axis with blades 22 during the washing cycle, making it rotate, and that after being uncoupled from the axis with blades 22, touches the tub 20 during the spinning cycle (pursuant to figure 31 ).
2o Figure 32 illustrates the application of the circumscribed ring-motor 1 in the same manner as in figure 30, only with the blade axis separated from direct contact with the clothing. For this purpose a circumscribed ring-motor 1 is established with part, i.e. the stator ring 4, supported on the outside bottom 2s surface of the tank 19, and that totally circumscribes the rotor ring 2, which in turn is coupled on the surface of a disc 13, which transmits the circular or alternate movement of the rotor 2 to the axis with blades 22, separated from direct contact with the clothing by a screen or grid 23, through a central driving axis 14, positioned in the center of the disc 13, which overreaches the tank 19, and touches the axis with blades 22 during the washing cycle, making it rotate, and t hat after being uncoupled from the axis with blades 22, touches the tub 20 s during the spinning cycle.
Figure 33 illustrates the application of the flat ring-motor 6 in the same manner as in figure 31, only with the blade axis separated from direct contact with the clothing. For this purpose a flat ring-motor 6 is established with part, i.e., the stator ring io 9, supported on the outside bottom surface of the water contention tank, tank 19, which completely faces the rotor ring 7, which in turn is coupled on the surface of a disc 13, and transmits the circular or alternate movement of the rotor 7 to the axis with blades 22, separated from direct contact with the clothing by a screen or grid 23, is through a central driving axis 14, positioned in the center of the disc 13, which overreaches the tank 19, and touches the axis with blades 22 during the washing cycle, making it rotate, and that after being uncoupled from the axis with blades 22, touches the tub 20 during the spinning cycle.
2o The improvements established herein can also be applied to mini clothes dryers, which like mini washing machines eliminate or reduce various mechanical components used in transmission such as pulleys, belts and gears, as illustrated in figures 34, 35, 36, 37, 38 and 39.
2s In figure 34, the clothing is accessed from the front part of the mini dryer. One of the parts of the circumscribed ring-motor 24, the stator 26, is integrated to the outside posterior surface of the tank 19; and the other part, the rotor 25, is integrated to the surface of a disc 13, which transmits the circular movement of the rotor 25 to the tub 20, through a driving axis 14.
In figure 35, part of the s circumscribed ring-motor 24 of the mini drier, i.e. the stator 26, is coupled on the immobile front surface or coupled to the front surface of the tub 20.
In figure 36, part of the circumscribed ring-motor 24 of the mini drier, i.e. the stator 26, is io coupled on the surface of the clothing access lid 21 of the clothes dryer, while the other part, the rotor 25, is coupled on the surface of the tub 20, thus executing the circular and alternate movement of the aforementioned tub 20.
In figure 37, as in figure 34, one of Is the parts of the flat ring-motor 27 of the mini dryer, the stator 29, is integrated to the outside posterior surface of the tank 19; and the other part, the rotor 28, is integrated to the surface of a disc 13, which transmits the circular movement of the rotor 28, to the tub 20, through an axis 14.
2o In figure 38, as in figure 35, part of the flat ring-motor 27 of the mini dryer, i.e., the stator 29, is coupled on the immobile front surface of the tank 19; and the other part of the motor, consisting of the rotor 28, is coupled to the front surface of the tub 20.
2s In figure 39, as in figure 36, part of the flat ring-motor 27, i.e. the stator 29, is coupled on the surface of the clothing access lid 21 of the dryer, while the other part, the rotor 28, is coupled on the surface of the tub 20, thus executing the circular movement of this tub 20.
Finally the applicant has developed other variations that are related to the fact that we have fully separated the circumscribed and flat ring-motor from the assembly s formed by the tank and tub, hence the ring-motor is mounted as an autonomous component, totally independent and now called an agitator, responsible for the movement of the tank and tub assembly for washing, spinning or drying.
The tub and tank assembly can io occasionally be coupled to the aforementioned agitator for the execution of an intended task.
In this manner we obtain some advantages, including that of being able to couple varied tanks with dimensions suited to the quantity of clothing.
is Another advantage of an operational nature consists of having the components responsible for the movement, in the case of the ring-motor, of the remaining assembly, tub and tank, totally separate, thus permitting the separate packaging, transport, handling and even purchase of the aforementioned 2o components.
In brief, the agitator is the independent ring-motor consisting of a rotor and stator appropriately mounted and encapsulated, which transmits the circular movement of the rotor through an axis fastened to the assembly, in the case of the 2s tank and tub, the central.
Figure 40 illustrates the aforementioned agitator 30, comprising a circumscribed electric ring-motor 1, with the stator ring 4, mounted on the internal perimetric structure of a disc 31, with a hole in its center 32. This disc fully circumscribes the rotor ring 2, which is coupled on the outside perimetric surface of a disc 33, which transmits the circular or alternate movement of the rotor 2 through an axis 34, positioned in the s center of disc 33, which overreaches the central hole 32 of the disk 31. In turn, a bearing 35 is lodged in this hole and surrounds the supports the aforementioned axis 34, thus guaranteeing the deriving movement of the rotor ring 2, further to the mounting and alignment of the entire assembly, which in turns is closed by a lid 36.
io Figure 41 shows the agitator assembly 37, now using the flat ring-motor 6, with the stator ring 9 mounted on the front of a disc 38, with a hole 39 in its center. This disc fully faces the rotor ring 7 in parallel, and this rotor is coupled on the front of another disc 40, which transmits the is circular or alternate movement of the rotor 7 through an axis 34, positioned in the center of the disc 40. This axis overreaches the central hole 39 of the disk 38. In turn, this hole has an lodged bearing 35, which surrounds and supports this axis 34, thus guaranteeing the deriving movement of the rotor ring 7, further to 2o the mounting and alignment of the entire assembly, which in turn is closed by a lid 36.
Figure 42 shows the agitator assembly 30, totally mounted and closed with its central axis 34.
These are obviously just a few 2s schematic examples. It is clear than any alterations introduced in this invention are included in and protected by this patent.
to Thus a series of technical and operational advantages was obtained in comparison with conventional clothes washers.
Continuing with studies and research on the topic, the Applicant has now developed other forms and is variations of the innovative electric motor and its respective applications.
The purpose of this patent is to substantially alter the concept of conventional clothes washing and drying machines in order to provide for the application of the 2o innovative ring-motor concept (circumscribed) and now also of the flat ring-motor and respective variations, in mini clothes washing and drying machines that are more compact than current ones. The circumscribed and flat ring-motor, encapsulated with plastic and protected from contact with water applied directly or indirectly on the 2s surface of the tank or tub serves as an excellent substitute for various normal mechanic components necessary for the movement of the washing tub, such as belts, pulleys, gears and gearbox, thus generating new advantages.
These advantages include the optimization of the washing process, with consequent economy of water, space and electric power, since the washing process is executed in a compact machine with much smaller dimensions than s current ones, which on average wash 5 kg and consume around 240 liters of water in their total cycle.
Another advantage of a constructive nature consists of the application of the aforementioned electric motor concept to the compact machine or mini washer mini dryer concept, to thus facilitating their construction and balancing further to simplifying their use.
Another advantage refers to the fact that part of the ring-motor can be coupled on the surface of the tank, of the tub, of the lid, of the axis with blades or on the outside lower is part of the tank, generating the circular or alternate movement of the washing chamber (tub) directly or indirectly without the assistance of secondary parts. In this manner the components are optimized the machine is consequently compacted.
The combination of the compact 2o machine and circumscribed ring-motor or flat ring-motor (with flat active sides facing each other) concepts can be applied to the agitation system (vertical cylindrical tanks) and to the tumbling system (horizontal cylindrical tanks), only now with reduced dimensions and with a specific internal anatomy that occasionally substitutes the axis 2s with blades.
Another advantage is the possibility of coupling part of this motor (estator) on the surface of the machine door while the other part (rotor) can be coupled on the surface of the tub. Hence when the door of the machine is opened, the rotor is automatically separated from the stator, turning it off and expanding the use and application of the concept.
An additional advantage refers to the s fact that the tub can be optionally removed at the end of the washing process and serve to transport the clothing.
Another advantage is related to the fact that we can use the electric ring-motor as an autonomous and independent component of the clothes tub assembly, that can to therefore be coupled circumstantially to execute specific tasks, in tanks of varied dimensions suited to the quantity of clothing.
Yet another advantage refers to the fact that the parts of the ring-motor, i.e., rotor and stator, are independently encapsulated in plastic, thus guaranteeing sealing is against water and the insulation of the current. For this purpose when the aforementioned parts are manufactured they will be injected with plastic or ferrite (syntherized) and subsequently polymerized.
The reduction of mechanic parts allows for a wider range of uses of electronic components that add 2o value and functionality to the washing machine.
The circumscribed ring-motor must be differentiated from the flat ring- motor. The former type has the basic components of a conventional motor: rotor (permanent magnets, electromagnets or even a squirrel grid) and stator (coil), only in this 2s case in a ring format, with one ring circumscribed to the other, i.e., one ring (rotor) with a smaller diameter totally covered by another ring (stator) with a large diameter or vice versa, thus obtaining the elements that form an electric motor, i.e., inductor and induced. An electric current is induced to this plastically encapsulated assembly protected from contact with water to generate a magnetic field, which drives the circular movement of the rotor around an axis.
The flat ring-motor has the same s components: rotor and ring-stator, only arranged in parallel, with the active sides of their rings facing, contrary to the previous one whose rings are circumscribed. Hence the ring or rotor disc with its permanent magnets are positioned equidistantly and with their active side facing the active side of the ring or coiled stator disc.
to However, in the two previous designs, it is possible to substitute the permanent magnets of the ring or ,rotor disc with a magnetic belt or squirrel grid, thus adapting the construction of the motor to the implicit requirements, whether for a synchronous or asynchronous motor.
is The use of permanent magnets is indicated in synchronous motors as we have precise control of the RPM (rotation per minute) and of the speed. In asynchronous motors where "slipping" is a known feature, the RPM and speed control are imprecise.
2o The ring format of the motor permits the arrangement of a greater number of permanent magnets on its surface, and respectively, a greater number of poles, making for a wide range of variations from high to reduced speeds automatically, without the need for a mechanic speed reducer (gearbox).
as The larger the quantity of poles and permanent magnets the greater the speed reduction possibility, and the better the physical-magnetic properties of the magnets, the fewer magnets required.
The use of natural or polymerized ferrite (synthesized) magnets in the rotor naturally establishes protection against the action of water and does away with the need for subsequent encapsulation. The use of neodimeo magnets that are s naturally more powerful reduces the number of necessary magnets in comparison to other less powerful ones.
Based on this, we can specifically use a BDC type Brushless motor, consisting of a stator ring with an embricado type three phase bearing with 90 poles, covered by a io magnetic core (crown of the stator) without teeth, and a rotor ring consisting of 90 permanent magnets arranged in parallel and equidistantly, supported by a magnetic conductor (rotor crown). The stator bearings are supplied with power by an "drive", with a single phase 220V inlet.
is However, by altering the number of permanent magnets, and consequently poles an ample constructive variation is obtained, suited to needs without altering the original concept.
Hence in other possible variations 2o a BDC type Brushless motor is established, consisting of a stator ring with embricado type three phase bearing, with an "N" number of poles (suited to the necessary power and speed), covered by a toothless magnetic core (stator crown) and a rotor ring, consisting of an "N" number of permanent magnets arranged in 2s parallel and equidistantly, supported by a magnetic conductor arch (rotor ring).
The supply and control of the speed and rotation of the motor is executed by an electronic Drive device that controls and establishes a low speed for washing and a higher one for spinning.
The application of part of the ring-motor on the body of the tank and tub represents a considerable s advantage, since the surface of the object to be spun is used to guarantee its mounting. However, the same motor components, i.e., rotor and stator, do not operate separately, hence the patent establishes the assembly of the ring- motor independently, for the distance and alignment of its rings (rotor and stator) to be maintained to unaltered, and for the motor to effectively perform the function for which it is designed.
One of the forms of independent assembly consists of coupling the motor components, i.e., rotor and stator respectively, on the surface of two discs arranged in parallel;
is the first equipped with a hole and central bearing and the second equipped with an activating axis coupled at its center. This axis fits into and overreaches the hole and the bearing of the first disc, thus maintain the assembly mounted and aligned.
Another form is to apply the 2o components of the ring-motor, i.e., rotor and stator , to the surface of the rings of a bearing with specific dimensions and properties, thus transforming the simple bearing into a "ring-motor bearing", i.e., a bearing with a coupled electric motor in its body.
The basic configuration of 2s conventional bearings consists of an internal ring and another external ring, separated by one or two tracks of spheres or ring rollers that guarantee the concentricity, assembly and independent movement of the rings.
This set of innovations serve to simplify the construction of the machines, reducing the number of component parts and making the viability of the new concept effectively more concrete.
On the other hand, this set of innovations also applies to conventional simple tumbling washers and dryers (horizontal cylindrical tanks) and washers and dryers that operate by agitation (vertical cylindrical tanks). With the application of the innovations developed here in the aforementioned conventional io machines, these become more compact, lighter and substantially simpler, both in constructive and operational terms.

In turn, this hole has a fitted bearing 15, which surrounds and supports the axis 14, thus guaranteeing the movement of the rotor ring 2, further to the mounting and alignment of the assembly.
is Figure 9 shows a perspective view with a cross-section of another form of independent assembly on the surface of a bearing (R). For this purpose a circumscribed ring-motor 1 is provided for, in which the rotor ring 2 and the stator ring 4 are respectively coupled on the surface of the internal bearing rings 16 2o and external bearing 17 of a bearing (R). In this case the external surface of the internal bipartite bearing ring 16 is used to fix a part of the circumscribed ring-motor 1, i.e., the rotor 2, and on the internal surface of the external bearing ring 17 the other part of the circumscribed ring-motor 1, i.e., the stator 4, or vice versa, separated 2s by two tracks of spheres or ring rollers 18, which guarantee the concentricity, assembly and independent movement of the rings, with the advantage of having cleared the central space or core of the rings to fix the object to be rotated directly in this space.

This entire disc faces the rotor ring 7 in parallel, and the rotor is coupled on the front of another disc 13, which transmits the circular or alternate movement of the rotor 7 through an axis 14, positioned in the center of the disc 13, which overreaches the central hole 12 of the disc 11. In turn, this hole has a fitted bearing 15, which is surrounds and supports the aforementioned part further to the mounting and alignment of the entire assembly.
The innovations arising from the use of the ring-motor permit operating advantages, including the possibility of using the actual surface of the basket and tank to fix part of the 2o ring-motor.
The subject matter of this patent refers to "Improvements Introduced to Clothes Washing and Drying Machines", according to which, to execute the circular or alternate movement of the washing tub in the so-called agitation system with a 2s vertical cylindrical tank, the following components are provided for: an encapsulated circumscribed ring-motor 1, with part, i.e., the stator ring 4, supported on the outside lower surface of the water containment tank (tank) 19, which entirely circumscribes the rotor ring 2, which in turn is coupled on the surface of a disc 13, and transmits the circular and alternate circular movement of the rotor 2, to the perforated washing chamber (tub) 20 containing the clothing, through a central axis 14, positioned in the center of the disc 13, which overreaches the s aforementioned tank 19, and touches the tub 20, thus causing its circular or alternate movement and permitting the optional removal of the aforementioned tub 20 at the end of the washing process (pursuant to figure 12).
To make the alternate circular io movement of the tub 20 in the agitation system in a more simplified manner, we have developed other forms. One of these consists of using the actual immobile top surface of the tank 19 to fix a part of the circumscribed ring- motor 1, i.e., the stator 4, properly encapsulated and protected from contact with water; and the other part of the motor, is consisting of the rotor 2, also encapsulated in plastic, coupled to the top surface of the tub 20 and totally covered by the stator ring 4, thus obtaining the elements of an electric motor, i.e.: rotor and stator that execute the alternate circular movement of the tub and at the end of the washing process permit the optional removal of ao the tub to transport the clothing, together with the rotor 2 (pursuant to figure 13).
Figure 14 illustrates another advantage concerning the possibility of coupling part of this encapsulated circumscribed ring-motor 1 on the surface of lid 21 of 2s the washing machine, i.e., stator 4, while the other part, the encapsulated rotor 2, can be coupled on the surface of the tub 20, permitting the circular and alternate movement of the aforementioned tub 20, thus expanding the use and application of the concept in the so-called agitation system, although emphasizing the importance of keeping the distance and alignment of the rotor 2 in relation to the stator 4, unaltered.
In addition, we can apply the s innovative concepts illustrated above in the agitation system with vertical cylindrical tub to the so-called tumbling system with a horizontal cylindrical tub.
Hence figure 15 illustrates a circumscribed ring-motor 1, with part, i.e., the stator ring 4, supported to on the outside posterior surface of the tank 19, which totally circumscribes the rotor ring 2, which in turn is coupled on the surface of a disc 13, and transmits the circular or alternate circular movement of the rotor 2, to the tub 20, through an axis 14 positioned in the center of the disc 13, which overreaches the aforementioned tank 19, is and touches the tub 20, thus causing the circular or alternate circular movement and permitting the optional removal of the aforementioned tub at the end of the washing process.
To executed the circular or alternate circular movement of the tub 20 in the tumbling system in a more 2o simplified manner, we have developed some other forms. One of these consists of using the actual immobile front surface of the tank 19, to fix a part of the circumscribed ring-motor 1, i.e., the stator 4, properly encapsulated and protected from contact with water; and the other part of the motor, consisting of the rotor 2, also encapsulated in 2s plastic and protected against contact with water, coupled to the front surface of the tub 20, totally circumscribed by the stator ring 4, thus obtaining the elements of an electric motor, i.e. rotor and stator that execute the circular or alternate circular movement of the tub and at the end of the washing process, permit the optional removal of the tank for use to transport the clothing, together with the rotor 2 (pursuant to figure 16).
Figure 17 illustrates another s advantage related to the possibility of coupling part of this encapsulated circumscribed ring-motor 1 on the surface of the lid 21 of the clothes machine, comprising a stator 4, while the other part consisting of a rotor 2 can be coupled on the surface of the tub 20, thus permitting its circular or alternate circular movement and to expanding the use and application of the concept in the so-called tumbling system.
Likewise the application of the flat ring-motor 6 is established in the six alternatives previously illustrated in figures 12, 13, 14, 15, 16 and 17, although considering the is difference in the design and arrangement of the rotor in relation to the stator, with the active sides of its rings or discs parallel and facing each other, contrary to the circumscribed ring-motor where the rotor ring is circumscribed to the stator ring or vice versa, as illustrated by figures 18, 19, 20, 21, 22 and 23.
2o In figure 18, as in figure 12, access to the tub 20 is made from the top of the machine, one of the parts of the encapsulated flat ring-motor 6, the stator 9, is integrated to the outside lower surface of the tank 19; and the other part, the rotor 7, is integrated to the surface of a disc 13, which transmits the alternate 2s circular movement of the rotor 7 to the tub 20 through the axis 14, central driver.
In figure 19, as in figure 13, part of the encapsulated flat ring-motor 6, i.e., the stator 9, is coupled on the immobile top surface of the tank 19, and the other part of the motor, consisting of the encapsulated rotor 7, is coupled to the upper surface of the tub 20.
In figure 20, as in figure 14, part of s the flat ring-motor 6, the stator 9, is encapsulated, coupled on fihe surface of the lid 21 of the washing machine, while the other part, i.e., the encapsulated rotor 7, is coupled on the surface of the tub 20, thus executing the circular and alternate movement of the aforementioned tub 20. In figure 21, as in figure 15, access to the tub 20 is made from io the front of the machine, and part of the flat ring-motor 6, the encapsulated stator 9, is coupled to the outside posterior surface of the tank 19; while another part, the rotor 7, is coupled to the surface of a disc 13, which transmits the alternate circular movement of the rotor 7 to the tub 20 through an axis 14, central driver.
is Ln figure 22, as in figure 16, part of the encapsulated flat ring-motor 6, i.e. the stator 9, is coupled on the immobile front surface of the tank 19, and the other part of the motor, consisting of the encapsulated rotor 7, is coupled to the front surface of the tub 20.
2o In figure 23 with horizontal cylindrical tanks, as in figure 17, part of the flat ring-motor 6, the encapsulated stator 9, is coupled on the surface of the clothing access lid 21 of the washing machine, while the other part, i.e., the encapsulated rotor 7, is coupled on the surface of the tub 2s 20, thus executing the circular and alternate movement of this tub 20.
Furthermore, and also thanks to the use of these innovations in the machines describe above, another highly important application is obtained: in simple tumbling with a tilted washing chamber, preferably at around 451; this promotes an improved accommodation and a more homogeneous distribution of clothing inside the tub, which is now tilted, besides combining the s ergonomic advantages of machines that wash by agitation, where access to the clothing is made from the top of the machine, with the advantages of washing by simple tumbling, as illustrated by figures 24, 25, 26, 27, 28 and 29.
In figure 24, as in figure 12, access to to the tub 20 is made at the top of the machine, which is tilted. One of the parts of the circumscribed ring-motor 1, the stator 4, is integrated to the outside top surface of the tank 19; and the other part, the rotor 2, is integrated to the surface of a disc 13, which transmits the alternate circular movement of the rotor 2 to the tub 20 through an is axis 14.
In figure 25, as in figure 13, part of the circumscribed ring-motor 1, i.e., the stator 4, is coupled on the immobile upper surface of the tank 19, now tilted, and the other part of the motor, consisting of the rotor 2, is coupled to the top surface of 2o the tub 20.
In figure 26, as in figure 14, part of the circumscribed ring-motor 1, i.e., the stator 4, is coupled on the surface of the lid 21 of the washing machine, now tilted, while the other part (rotor 2) is coupled on the surface of the tub 20, thus 2s executing the circular and alternate movement of this tub 20.
In figure 27, as in figure 18, access to the tub 20 is made via the tilted top part of the machine, only with the flat ring-motor 6, with one of its parts, the stator 9, integrated to the outside lower surface of the tank 19; and another part, the rotor 7, integrated to the surface of a disc 13, which transmits the circular or alternate movement of the rotor 7 to the tub 20 through an axis 14.
Figure 28, like figure 19, now shows s part of the flat ring-motor 6, i.e., the stator 9, coupled on the immobile top surface of the tank 19, now tilted, and the other part of the motor, consisting of the rotor 7, coupled to the top surface of the tub 20.
In figure 29, as in figure 20, part of the flat ring-motor 6, the stator 9, is coupled on the surface of the lid io 21 of the now tilted washing machine, while the other part (rotor 7) is coupled on the surface of the tub 20, thus executing the circular and alternate movement of this tub 20.
We can extend the application of the circumscribed ring-motor 1, and of the flat motor 6, in machines that is wash by agitation with vertical tanks, although using an axis with blades. Hence the alternate movement of the respective axis with blades inside the tank represents the element responsible for friction between the water and the clothing. This friction can be caused by direct contact of the axis with blades and the water and clothing, or by 2o indirect contact, if we have a smaller axis with blades separated from direct contact with the clothing by a screen or perforated grid, in this case the axis with blades moves the water which in turn moves the clothing.
To execute the alternate circular 2s movement of the axis with blades 22 inside the tub 20 using the so-called agitation system, a circumscribed ring-motor 1 is established with part, i.e., the stator ring 4, supported on the outside bottom surface of the tank 19, which circumscribes the entire rotor ring 2, which in turn is coupled on the surface of a disc 13, and transmits the circular or alternate movement of the rotor 2 to the axis with blades 22, through a central driving axis 14, positioned in the center of the disc 13, which overreaches the tank 19, and touches the axis with s blades 22 during the washing cycle, making it rotate, and that after being uncoupled from the axis with blades 22, touches the tub during the spinning cycle (pursuant to figure 30).
To execute the alternate circular movement of the axis with blades 22 inside the tub 20, using the so-lo called agitation system, a flat ring-motor 1 is established with part, i.e.
the stator ring 9, supported on the outside bottom surface of the water contention tank, tank 19, which completely faces the rotor ring 7, which in turn is coupled on the surface of a disc 13, and transmits the circular or alternate movement of the rotor 7 to the axis with blades is 22, through a central driving axis 14, positioned in the center of the disc 13, which overreaches the tank 19, and touches the axis with blades 22 during the washing cycle, making it rotate, and that after being uncoupled from the axis with blades 22, touches the tub 20 during the spinning cycle (pursuant to figure 31 ).
2o Figure 32 illustrates the application of the circumscribed ring-motor 1 in the same manner as in figure 30, only with the blade axis separated from direct contact with the clothing. For this purpose a circumscribed ring-motor 1 is established with part, i.e. the stator ring 4, supported on the outside bottom 2s surface of the tank 19, and that totally circumscribes the rotor ring 2, which in turn is coupled on the surface of a disc 13, which transmits the circular or alternate movement of the rotor 2 to the axis with blades 22, separated from direct contact with the clothing by a screen or grid 23, through a central driving axis 14, positioned in the center of the disc 13, which overreaches the tank 19, and touches the axis with blades 22 during the washing cycle, making it rotate, and t hat after being uncoupled from the axis with blades 22, touches the tub 20 s during the spinning cycle.
Figure 33 illustrates the application of the flat ring-motor 6 in the same manner as in figure 31, only with the blade axis separated from direct contact with the clothing. For this purpose a flat ring-motor 6 is established with part, i.e., the stator ring io 9, supported on the outside bottom surface of the water contention tank, tank 19, which completely faces the rotor ring 7, which in turn is coupled on the surface of a disc 13, and transmits the circular or alternate movement of the rotor 7 to the axis with blades 22, separated from direct contact with the clothing by a screen or grid 23, is through a central driving axis 14, positioned in the center of the disc 13, which overreaches the tank 19, and touches the axis with blades 22 during the washing cycle, making it rotate, and that after being uncoupled from the axis with blades 22, touches the tub 20 during the spinning cycle.
2o The improvements established herein can also be applied to mini clothes dryers, which like mini washing machines eliminate or reduce various mechanical components used in transmission such as pulleys, belts and gears, as illustrated in figures 34, 35, 36, 37, 38 and 39.
2s In figure 34, the clothing is accessed from the front part of the mini dryer. One of the parts of the circumscribed ring-motor 24, the stator 26, is integrated to the outside posterior surface of the tank 19; and the other part, the rotor 25, is integrated to the surface of a disc 13, which transmits the circular movement of the rotor 25 to the tub 20, through a driving axis 14.
In figure 35, part of the s circumscribed ring-motor 24 of the mini drier, i.e. the stator 26, is coupled on the immobile front surface or coupled to the front surface of the tub 20.
In figure 36, part of the circumscribed ring-motor 24 of the mini drier, i.e. the stator 26, is io coupled on the surface of the clothing access lid 21 of the clothes dryer, while the other part, the rotor 25, is coupled on the surface of the tub 20, thus executing the circular and alternate movement of the aforementioned tub 20.
In figure 37, as in figure 34, one of Is the parts of the flat ring-motor 27 of the mini dryer, the stator 29, is integrated to the outside posterior surface of the tank 19; and the other part, the rotor 28, is integrated to the surface of a disc 13, which transmits the circular movement of the rotor 28, to the tub 20, through an axis 14.
2o In figure 38, as in figure 35, part of the flat ring-motor 27 of the mini dryer, i.e., the stator 29, is coupled on the immobile front surface of the tank 19; and the other part of the motor, consisting of the rotor 28, is coupled to the front surface of the tub 20.
2s In figure 39, as in figure 36, part of the flat ring-motor 27, i.e. the stator 29, is coupled on the surface of the clothing access lid 21 of the dryer, while the other part, the rotor 28, is coupled on the surface of the tub 20, thus executing the circular movement of this tub 20.
Finally the applicant has developed other variations that are related to the fact that we have fully separated the circumscribed and flat ring-motor from the assembly s formed by the tank and tub, hence the ring-motor is mounted as an autonomous component, totally independent and now called an agitator, responsible for the movement of the tank and tub assembly for washing, spinning or drying.
The tub and tank assembly can io occasionally be coupled to the aforementioned agitator for the execution of an intended task.
In this manner we obtain some advantages, including that of being able to couple varied tanks with dimensions suited to the quantity of clothing.
is Another advantage of an operational nature consists of having the components responsible for the movement, in the case of the ring-motor, of the remaining assembly, tub and tank, totally separate, thus permitting the separate packaging, transport, handling and even purchase of the aforementioned 2o components.
In brief, the agitator is the independent ring-motor consisting of a rotor and stator appropriately mounted and encapsulated, which transmits the circular movement of the rotor through an axis fastened to the assembly, in the case of the 2s tank and tub, the central.
Figure 40 illustrates the aforementioned agitator 30, comprising a circumscribed electric ring-motor 1, with the stator ring 4, mounted on the internal perimetric structure of a disc 31, with a hole in its center 32. This disc fully circumscribes the rotor ring 2, which is coupled on the outside perimetric surface of a disc 33, which transmits the circular or alternate movement of the rotor 2 through an axis 34, positioned in the s center of disc 33, which overreaches the central hole 32 of the disk 31. In turn, a bearing 35 is lodged in this hole and surrounds the supports the aforementioned axis 34, thus guaranteeing the deriving movement of the rotor ring 2, further to the mounting and alignment of the entire assembly, which in turns is closed by a lid 36.
io Figure 41 shows the agitator assembly 37, now using the flat ring-motor 6, with the stator ring 9 mounted on the front of a disc 38, with a hole 39 in its center. This disc fully faces the rotor ring 7 in parallel, and this rotor is coupled on the front of another disc 40, which transmits the is circular or alternate movement of the rotor 7 through an axis 34, positioned in the center of the disc 40. This axis overreaches the central hole 39 of the disk 38. In turn, this hole has an lodged bearing 35, which surrounds and supports this axis 34, thus guaranteeing the deriving movement of the rotor ring 7, further to 2o the mounting and alignment of the entire assembly, which in turn is closed by a lid 36.
Figure 42 shows the agitator assembly 30, totally mounted and closed with its central axis 34.
These are obviously just a few 2s schematic examples. It is clear than any alterations introduced in this invention are included in and protected by this patent.
