Benefits of technology

[0022]The invention is suitable particularly for apparatuses designed in the manner of commercial washing machines, namely what are referred to as continuous process washing machines. A washing machine of this type has an elongate, overall rotationally driveable drum with a plurality of consecutive chambers, at least one of the chambers being assigned an outer drum. An outer drum is customarily located where treatment liquid, such as pre-washing liquid, clear washing liquid and/or rinsing liquid, can be conducted out of the drum or liquids

Problems solved by technology

In addition, the treatment liquid absorbs dirt washed out of the laundry and possibly foreign materials which, for the most part, are heavier than t

Embodiment Construction

[0029]The invention is described below with reference to an apparatus, in the form of a continuous process washing machine 10, for washing and rinsing items of laundry. However, the invention is not restricted thereto.

[0030]The continuous process washing machine 10 shown schematically in FIG. 1 has a cylindrical drum 12 which is rotationally driveable about a preferably horizontal axis of rotation 11. The axis of rotation 11 lies on the longitudinal center axis of the drum 12. The laundry to be washed is transported from the left to the right (with respect to FIG. 1) in the treatment direction 13 through the rotationally driven drum 12.

[0031]A plurality of chambers 15 which are consecutive in the treatment direction 13 are formed by transversely directed partitions 14 in the drum 12. One laundry batch is treated, in particular washed and rinsed, in each chamber 15. The chambers 15 may be identical in size, but may also differ in size. The partitions 14 have central or eccentric open...

Abstract

A method and apparatus for washing items of laundry that makes provision to continuously filter the treatment liquid during the washing operation. As a result, interfering attendant materials in and on the treatment liquid are successively removed during the washing operation, which increases the efficacy of the washing operation. Provision is preferably made to remove both lighter constituents, such as foam and lint, from the treatment liquid and also to filter heavier constituents, such as impurities washed out of the items of laundry, from the treatment liquid using the same filter. The same filter can also be used, after the end of the washing operation, to filter the treatment liquid to be let out and to temporarily store the treatment liquid in a collecting tank before the filtered treatment liquid is reused. The invention thus permits multiple functions of the filter.
