Description
"DISPOSITIVO E PROCESSO DE ACIONAMENTO DO CESTO DE UMA MÁQUINA DE LAVAR ROUPA DURANTE A ETAPA DE CENTRIFUGAÇÃO" "DEVICE AND DRIVING PROCESS OF THE BASKET OF A WASHING MACHINE DURING THE SPIN"
FUNDAMENTOS DA INVENÇÃO BACKGROUND OF THE INVENTION
A presente invenção se refere a um dispositivo e a um processo de acionamento do cesto de uma máquina de lavar roupa durante a centrifugação. The present invention relates to a device and a method of activating a washing machine basket during spinning.
Conforme é de conhecimento geral, em uma máquina de lavar roupa convencional, conforme mostrada na figura 1 , um motor elétrico A aciona uma polia/eixo B por meio de uma correia C. Na fase de lavagem da roupa, o dito eixo B aciona somente o agitador D até que a dita fase seja concluída. Em seguida, a embreagem é acoplada e o eixo B passa a acionar, conjuntamente, o agitador D e o cesto E disposto dentro do tanque F. Com a centrifugação, a água contida no cesto é removida através dos orifícios G situados na parede do dito cesto e escoa pelo tanque F, eliminando, assim, o excesso de água das roupas. Em seguida, as roupas podem ser retiradas da máquina de lavar e colocadas para secar. As is well known, in a conventional washing machine, as shown in Figure 1, an electric motor A drives a pulley / shaft B by means of a belt C. In the laundry phase, said shaft B drives only the agitator D until said phase is completed. Then the clutch is coupled and the shaft B starts to drive the stirrer D and the basket E arranged inside the tank F together. With the centrifugation, the water contained in the basket is removed through the holes G located in the wall of the said one. basket and drains through tank F, thus eliminating excess water from clothing. The clothes can then be removed from the washing machine and put to dry.
TÉCNICA ANTERIOR E SEUS INCONVENIENTES PRIOR TECHNIQUE AND ITS INCONVENIENTS
Conforme citado anteriormente, para se iniciar a fase de centrifugação é necessário que a embreagem da máquina de lavar seja acionada, de modo que o eixo acione, simultaneamente, o agitador e o cesto que contém as roupas. Normalmente, conforme mostrado na figura 2, as embreagens da técnica anterior apresentam uma mola H que aciona um pino I, o qual, por sua vez, aciona a alavanca J de acionamento da embreagem (não mostrada na figura), desacoplando a dita embreagem durante a fase de lavagem. Na fase de centrifugação, um tracionador eletro-mecânico L traciona uma cinta de plástico M, o que causa o acionamento da alavanca J e, conseq Cientemente, o acoplamento da embreagem, fazendo com que o cesto E gire junto com o agitador D. Observa-se ainda na figura uma chapa de cobertura N cobrindo o conjunto formado pelo motor elétrico A, polia B e correia C. As mentioned above, to start the spinning phase it is necessary that the washer clutch is engaged so that the shaft simultaneously operates the stirrer and the basket containing the laundry. Typically, as shown in Figure 2, prior art clutches feature a spring H that drives a pin I, which in turn drives the clutch drive lever J (not shown in figure), uncoupling said clutch during the washing phase. In the centrifugation phase, an electro-mechanical tractor L pulls a plastic belt M, which causes the lever J to act and, consequently, the clutch to engage, causing the basket E to rotate along with the agitator D. Also shown in the figure is a cover plate N covering the assembly formed by the electric motor A, pulley B and belt C.
Um inconveniente da técnica anterior é o fato de que a embreagem em si e todos os demais componentes destinados ao seu acionamento apresentam um custo elevado. A drawback of the prior art is the fact that the clutch itself and all other components intended for its operation are expensive.
