Description
Maquina lavadora Washing machine
El presente invento se refiere a una maquina lavadora, que comprende un mueble en forma de caja, en el que se ha montado una cubeta que contiene un tambor rotativo, habiendose instalado entre el mueble y la cubeta un The present invention relates to a washing machine, which comprises a cabinet-shaped piece of furniture, in which a tray containing a rotating drum has been mounted, and between the furniture and the tray a
5 dispositivo tubular deformable para permitir la carga y la descarga de ropa a traves de aberturas alineadas del mueble, de la cubeta y del tambor y para prevenir el derrame de agua afuera de la cubeta. Una maquina lavadora semejante, que revela las caracteristicas del preambulo de la reivindicaci6n 1, se conoce por el documento EP 0 213 385 A. 5 deformable tubular device to allow the loading and unloading of clothing through aligned openings of the furniture, the bucket and the drum and to prevent the spillage of water out of the bucket. A similar washing machine, which reveals the features of the preamble of claim 1, is known from EP 0 213 385 A.
En las conocidas maquinas lavadoras, el dispositivo tubular deformable de antes es un fuelle de caucho, que lleva a 10 cabo las funciones expuestas anteriormente. In the known washing machines, the deformable tubular device from before is a rubber bellows, which performs the functions set forth above.
La carga desequilibrada provoca que la unidad de lavado, es decir, el conjunto de la cubeta y el tambor se mueva dentro del mueble transmitiendo fuerzas y vibraciones a traves de amortiguadores, muelles y fuelle al mueble y, por consiguiente, tambien al suelo. The unbalanced load causes the washing unit, that is, the whole of the bucket and the drum to move inside the furniture, transmitting forces and vibrations through dampers, springs and bellows to the furniture and, consequently, also to the floor.
A pesar de la flexibilidad de los conocidos fuelles de caucho, el material y la rigidez geometrica de los mismos Despite the flexibility of the known rubber bellows, the material and the geometric stiffness of the same
15 provoca la transmisi6n de fuerzas suficientes entre la unidad lavadora y el mueble, especialmente fuerzas tangenciales. Estas cargas elevadas crean fuerzas de reacci6n considerables, que requieren un disefo que utiliza un espacio que se podria usar mejor utilizando una unidad de lavado mayor. 15 causes the transmission of sufficient forces between the washing unit and the furniture, especially tangential forces. These high loads create considerable reaction forces, which require a design that uses a space that could be better used using a larger washing unit.
Un objeto del presente invento es proporcionar una maquina lavadora del tipo especificado al principio de la descripci6n, que no presente los problemas tecnicos expuestos antes sin incrementar el coste total de la maquina. An object of the present invention is to provide a washing machine of the type specified at the beginning of the description, which does not present the technical problems set forth above without increasing the total cost of the machine.
20 El objeto de expuesto antes se consigue gracias a las caracteristicas enumeradas en las reivindicaciones adjuntas. The object set forth above is achieved thanks to the features listed in the appended claims.
La idea basica subyacente en el presente invento es reemplazar el fuelle de caucho tradicional por un componente hecho con un tejido o una tela de una rigidez muy baja entre la unidad lavadora y el mueble con fines de sellado. Con el termino "tela" quiere decirse cualquier tipo de material tejido, de punto o de fieltro. La ventaja, comparada con las soluciones existentes, es decir, los fuelles de caucho, es principalmente la elevada flexibilidad e independencia 25 de las caracteristicas geometricas de "desacoplamiento" de la tela en comparaci6n con la rigidez del material y de la geometria de las juntas estancas de caucho corrientes. La tela no se torcera bajo la carga tangencial, no creando, por tanto, elevadas fuerzas de reacci6n, lo que puede tomar en consideraci6n un disefo, que utilice menos espacio para la estructura mecanica. En consecuencia, se reducen ruidos y las vibraciones a una dimensi6n sorprendente e inesperada si los comparamos con las maquinas, que utilizan los fuelles de caucho tradicionales. El menor nivel de 30 fuerzas y vibraciones entre la unidad lavadora y el mueble permite una velocidad de rotaci6n mayor, al mismo tiempo que incrementa la vida del aparato. Segun una realizaci6n preferida del presente invento, con el fin de tener propiedades homogeneas del componente de tela, puede producirse este ultimo utilizando una labor de punto tubular continua o una labor de punto inconsutil con objeto de evitar cualquier cambio de espesor en toda la superficie del dispositivo tubular hecho de tela. Los dos extremos del dispositivo tubular pueden usar el cosido para The basic idea underlying the present invention is to replace the traditional rubber bellows with a component made with a fabric or a fabric of a very low stiffness between the washing unit and the furniture for sealing purposes. With the term "fabric" it means any type of knitted, knitted or felt material. The advantage, compared to existing solutions, that is, rubber bellows, is mainly the high flexibility and independence of the geometric characteristics of "decoupling". of the fabric compared to the rigidity of the material and the geometry of the current rubber seals. The fabric is not twisted under the tangential load, thus not creating high reaction forces, which may take into consideration a design that uses less space for the mechanical structure. Consequently, noise and vibration are reduced to a surprising and unexpected dimension if we compare them with the machines, which use traditional rubber bellows. The lower level of 30 forces and vibrations between the washing unit and the cabinet allows a higher rotation speed, while increasing the life of the apparatus. According to a preferred embodiment of the present invention, in order to have homogeneous properties of the fabric component, the latter can be produced using a continuous tubular knitting work or a seamless knitting work in order to avoid any change in thickness over the entire surface of the fabric. tubular device made of cloth. The two ends of the tubular device can use sewing to
35 encerrar elementos de uni6n (por ejemplo, juntas t6ricas de caucho o metal toroidal o muelles polimericos) para fijar el dispositivo a la cubeta, por un lado, y al mueble, por otro. 35 enclose joining elements (for example, rubber or toroidal metal o-rings or polymeric springs) to fix the device to the cuvette, on the one hand, and to the furniture, on the other.
Mas caracteristicas y distintivos segun el presente invento se aclararan con la siguiente descripci6n detallada en relaci6n con el dibujo adjunto, que muestra la aplicaci6n de un sellado de tela un estado actual de la tecnica de la maquina lavadora de carga superior. More features and distinctions according to the present invention will be clarified with the following detailed description in relation to the attached drawing, which shows the application of a fabric seal a current state of the art of the top-loading washing machine.
40 Incluso si la presente descripci6n de una posible realizaci6n del invento esta enfocada a una maquina lavadora de carga superior, esta claro que la soluci6n del presente invento puede utilizarse tambien para maquinas lavadoras de carga frontal. Even if the present description of a possible embodiment of the invention is focused on a top-loading washing machine, it is clear that the solution of the present invention can also be used for front-loading washing machines.
