Drum washing machine with agitator

The invention "refers to a washing machine with Preferably a cylindrical washtub and one coaxial in it arranged, rotatably mounted washing drum »one over the drum axis contains rotatably mounted central laundry mover or agitator.

Such drum washing machines are known in different designs. Different arrangements have also been proposed in order to remedy the difficulties arising from uneven weight distribution in the washing container when the washing drum rotates in such washing machines. For this it is usually necessary to flexibly mount the washing tub, including the rotating drum and its agitator arranged in it, on the housing of the washing machine ₀

The invention is directed to a special design of this flexible bearing, which sioh by simplicity, easy assembly and disassembly. this is achieved according to the invention in that the wash tub with

its bottom surface on an upper bearing lug of the gearbox housing sits and the frame connecting the parts has supporting supports fixed to the circumference of the wash tub, with their lower ends on one below the gear housing Attack arranged support plate, connected by inwardly protruding support webs with the gear housing and by means of "The springs on the bottom of the machine housing are tensioned,

In a further embodiment of the invention, the bottom surface of the machine housing expediently has a central support base with a spherically arched circumferential surface, while the lower support plate of the support supports is adapted to the shape of this base and supported with a friction ring on the base edge _o

The drive motor is conveniently seated in an adjustable position next to the gear housing on a lower support plate of the Support frame β For additional reduction of unbalance - The wash tub can bump into when the washing drum is turned be provided with a counterweight on its opening edge »
