Abstract

1,121,199. Tumbler driers. WESTINGHOUSE ELECTRIC CORP. 14 June, 1967 [20 June, 1966], No. 27370/67. Heading F4G. [Also in Division G1] The moisture content of clothes in a heated drum dryer is measured electrically to control the time during which heated air is supplied. A moisture sensor 34 (Figs. 2, 4) is mounted on the inner surface of the drum 11 near each of a plurality of equispaced tumbling vanes 33, and comprises two interdigitated electrodes 37, 38, the former being earthed to the main structure by fixing screw 39, and the latter connected by insulated screw 41 to a continuous metal band 44 on the outer surface of the drum, which is contacted by a spring-loaded carbon brush (51, Fig. 5, not shown) as the drum revolves. The electrodes 37, 38 are periodically in contact with the tumbling clothes, and the electrical resistance between them is inversely proportional to the degree of dampness of the clothes. The control circuit (Fig. 3) includes a switch 31 for selecting the voltage to be applied to heater 24, and a cam 59, initially set to close contacts 69, 70 and 71, 72 to energize the circuit. Motor 19 drives the drum 11. When the clothes 55 are part dry, the voltage drop across electrodes 37, 38 rises sufficiently to fire a neon tube 77, followed by controlled rectifier 74, completing the energizing circuit for timer motor 58, which drives the cam 59 until the circuit is again broken. Adjustable resistor 57 in series with the moisture sensor 34 controls the moisture level at which timer motor 58 starts. Thermostat switches 82, 83 are incorporated in the circuit.
