Definitions
- the present invention relates to the floating basket and clutch applied to the top-loading washing machine, more precisely, the object of this application includes the combination of a floating basket coupled to a set of vertically moving clutch parts and along the drive shaft due to the presence or absence of water in the machine tank;
- the floating basket and clutch assembly allows wash and spin functions to be performed with reduced part numbers and high efficiency over conventional models.
- top load or “top load” type washing machines are equipment with an upper door that includes a tank, a basket and an agitator or impeller mounted on a vertical axis.
- Most “top loading” machine models have the vertical shaft coupled with a drive system consisting of a motor, gearbox and clutch.
- the work performed by the clutch of a washing machine is to enable the engine and gearbox to operate programmatically within certain variations of the vertical shaft output rotation speed to which they are located.
- the agitator and the basket are linked so that they perform the washing operation, that is, of oscillating movement of the agitator in relation to the basket, and where the soap and water are stirred between the tissues, removing the dirt of these.
- the agitator and basket remain stationary, allowing the wash water to drain so that, in one last operation, said agitator and baskets are rotated so that they rotate together at a high speed, setting up the spin operation that expels excess water trapped in clothing and fabrics.
- Conventional clutches for the most part, use a gear and spring mechanism to shift engine power transmission between the wash and dehydration steps.
- Conventional clutch springs provide a means for effecting power transmission between the motor and the rotary agitator and the basket.
- Each conventional clutch spring requires high precision in its number of turns, and depends on calculations regarding its internal diameter, among others.
- electromagnets, actuators, lever arms and other components are required to control the movement of the clutch springs. Therefore, the conventional clutch mechanism has a complicated construction resulting in increased production cost.
- a floating clutch system that requires a transmission system, unlike the object in question, is the Brazilian document of n. PI 0605507-9 (Mabe) which deals with a floating clutch with two concentric axes, where, through a movable body, energy can be transmitted from one axis to the other by means of an indented disc which engages or disengages by vertical displacement in a cylindrical part, fixed to the agitator, due to the presence of some fluid, transmitting the torque of the inner shaft to the coupling and, from this, to the other parts.
- the motor is of type DD (direct drive) and transmits the power to the axle set by transmission system.
- the floating basket and clutch assembly applied to the agitator washing machine has as its main objective to provide that a top-loading washing machine has a specific constructivity to engage specifically and efficiently. , the floating basket mechanism and gear assembly to perform wash and spin functions.
- the floating basket and clutch assembly includes a drive shaft which: (i) at the lower end receives the rotate command from the engine; (ii) the upper end is coupled to the agitator or impeller base and imposes oscillating motion thereon; (iii) in the middle region provides means that allow the vertical displacement of the basket to perform the centrifugation operation.
- a first gear mechanism formed by a cylindrical bearing and provided with external radial teeth, while the median region of said axis is housed another cylindrical bearing with internal radial teeth, which in turn is fixed to the inner base of the tank.
- a floating mechanism formed by the floating basket provided with coupling means to a set of three vertically movable floating clutch parts, two of which are called crowns, one upper and the lower one, each provided with internal and external teeth, which can engage said upper and lower bearings.
- the centerpiece of the floating assembly comprises an inverted chamber or cup whose upper base is fixed by screws to the upper floating crown and its lower base is fixed also by screws to the floating basket and the lower crown, thus forming a floating assembly. able to engage and disengage from the fixed bearings.
- the wash or spin function is activated by the presence or absence of water in the floating assembly.
- the basket moves upwards vertically along the drive shaft, disengaging the upper fixed bearing assembly, but engaging said assembly on the lower fixed bearing, thereby parking the basket and allowing the shaft to impose swinging motion on the agitator, washing the laundry .
- the innovation is simple and eliminates the need to employ several other conventional components, thereby reducing costs without compromising agitation and centrifugation operations.
- the upper and lower gear assemblies are easy to produce and considerably reduce or reduce maintenance labor, not to mention that in the event that any of the parts of such gear assemblies need to be replaced, the cost is low in market as they are made of plastic.
- Figure 1 is a perspective view of a top load washing machine illustrating the basket and the agitator in evidence, as well as the drive system shaped by the motor, pulley, belt and drive shaft;
- Figure 2 is an enlarged sectional side view of the entire innovative assembly, namely floating basket, drive shaft, fixed bearings and small motor;
- Figure 2A is a perspective view and partial section of the elements that make up the clutch and the fixed bearings;
- Figures 3A and 3B show the bottom view of the basket and an enlarged side sectional view of the base of the basket illustrating the flotation chambers;
- Figures 4A, 4B and 4C show, respectively, the upper fixed bearing and upper crown in perspective and side view of both in mounted position
- Figures 5A, 5B and 5C show, respectively, the lower fixed bearing and the perspective lower crown and side view of both in assembled position
- Figures 6A, 6B and 6C depict, in detail and in upper and lower perspective, the intermediate float chamber integrating the clutch with respect to the basket base;
- Figure 7 is a sectional side view of the washing machine with sufficient water to carry out the washing operation, illustrating in greater detail the engaged upper gear assembly and the lower gear assembly in disengaged position, allowing the agitator swing and the basket remains parked;
- Figure 8 illustrates another view similar to the previous one, but the washing machine is without water, in the beginning of the centrifugation procedure, where the disengaged upper gear assembly and the lower gear assembly are observed in detail. allowing the agitator and basket to rotate together at high speed.
