Title: Display panel of full-automatic washing machine
Inventor: ISHIKAWA SHUNICHI
IPC: D06F39/00
Filed: 1993-06-03
Abstract: PURPOSE:To enable a clear display without need for displaying dehydration times at 50 and 60Hz respectively, by expressing numerical marks to certain terms meaning a state of dehydration for a display on a decorative sheet at one of more portions of a light emitting diode of an operation display panel. CONSTITUTION:The LED 39d on the decorative sheet 45 of an operation panel 38 expresses a state of dehydration; supposing a dehydration ability is the same in cases where the power source frequency is 50Hz and where it is 60Hz, the dehydration time in each case is different. Therefore, it is necessary to display both dehydration times for 50Hz and 60Hz respectively on the surface of the decorative sheet 45 and to make two kinds of times displayed only by this display. Further, it would greatly confuse consumers if they cannot understand the principle of the relation between the frequency (number of vibration) and the rotational frequency (number of rotation). Thus, the display of the state of dehydration by the LED 39d which is the light emitting diode is displayed in such terms as strong. standard, or weak, thereby simplifying the displays and preventing confusion.
