Method for controlling a metering device arranged movably on the inside of a dishwasher
First Claim
1. A method for controlling a dispenser apparatus reversibly positioned in the interior of a dishwasher, said method comprising the steps of:
- a. providing a light transmitting unit as part of said dispenser or as part of said dishwasher, said transmitting unit capable of emitting light pulses;
b. providing a light receiving unit as part of said dispenser or as part of said dishwasher, said receiving unit capable of receiving light pulses;
c. emitting a first light pulse I1 from said transmitting unit into the interior of said dishwasher, said pulse having a predefined pulse duration of lt1;
d. receiving said first light pulse I1 by said receiving unit, said reception initiating a time lapse measurement beginning at time tI1;
e. emitting a second light pulse I2 from said transmitting unit into the interior of said dishwasher, said pulse having a predefined pulse duration of lt2;
f. receiving said second light pulse I2 by said receiving unit, said reception terminating said time lapse measurement at time tI2;
g. calculating the time difference tI2−
tI1; and
h. encoding an information item or the portion of an information item based on said time difference.

Abstract
The present invention is a method for controlling a dispenser reversibly positioned in a dishwasher. The dispenser or dishwasher is configured with light transmission and receiving units. Light pulses are transmitted into the interior of the dishwasher and received by the receiving unit. The time difference (tI2−tI1) between the pulses is determined and that time difference is used to encode an information item or a portion of an information item. Such information items include a control signal, a measured value, an operating state of the automatic dishwasher and/or of the dispensing apparatus.
