KITCHEN DEVICE WITH AN APPLIANCE FOR DISPLAY OF MOTOR ROTATION FREQUENCY

摘要

FIELD: personal use articles.SUBSTANCE: invention relates to a kitchen device with an electric motor with adjustable rotation frequency intended for actuation of the treatment tool; the kitchen device contains an appliance for measurement of the motor rotation frequency and several optic indicator elements that are controlled by the measurement device and intended for display of the motor rotation frequency; assigned for each optic indicator element is a band of the motor rotation frequencies; the optic indicator elements are controlled by the measurement device so that an intensity of each indicator element equal to other than zero changes as the motor rotation frequency function within the bounds of the rotation frequency band assigned to it; if the motor rotation frequency exceeds the top threshold of band assigned to an indicator element the intensity of such optic indicator element assumes the same value as it assumes when the motor rotation frequency reaches the top threshold of the band concerned.EFFECT: invention enables creation of a kitchen device where the motor rotation frequency may be displaced with good resolution, the device characterised by design simplicity and cost-efficiency and a user friendly handling method.11 cl, 2 dwg
