DRYER FOR LAUNDRY Russian patent published in 2012 - IPC D06F58/00 

FIELD: textiles and paper.

SUBSTANCE: machine for drying laundry comprising a rotating drum (2) made with the ability to accommodate objects (3) of laundry to be dried, one or more means (4) of lifting laundry, located on the inner circumferential surface (5) of the drum (2), and an electrical circuit for determining the electrical resistivity and/or conductivity of laundry placed into the rotating drum (2), with each means (4) of lifting laundry comprises at least one first electrode (6) and at least one second electrode (7), electrically isolated from each other and made with the ability to contact with the laundry, and the first electrode (6) and the second electrode (7) are electrically connected, respectively, to the first conductive contact element (8) and the second conductive contact element (9) electrically isolated from each other and located on the outer circumferential surface (10) of the drum (2). The first conductive contact element (8) and the second conductive contact element (9) are in a constant galvanical connection during the drum (2) rotation respectively, the first sliding contact (11) and the second sliding contact (12) made with the ability to slide on the first conductive contact element (8) and the second conductive contact element (9), and both sliding contacts (11, 12) are electrically connected to the control unit (13) for measuring the electrical parameter depending on the residual moisture content in the dried laundry, which connects the first and second electrodes (6), (7). Each means (4) of lifting laundry comprises a first metal part that serves as the first electrode (6), and a second metal part that serves as the second electrode (7). These parts are located on the inner circumferential surface (5) of the drum (2) and are electrically insulated from each other by an insulating spacing element (18), and each means (4) of lifting laundry comprises two metal halves separated from each other by an insulating spacing element (18).

EFFECT: machine for drying laundry enables to define the electrical conductivity or electrical resistivity of laundry processed inside the rotating drum, even when the inner surface of the drum being in contact with the laundry, is made of electrically non-conductive material.
