Automatic Washing Machines

Low-Cost Acceleration Sensors in Automatic Washing Machines 

It is also possible for washing to be virtually evenly distributed when it is placed in the machine so that it spins with only a very small imbalance. However, if the batch of washing includes an item which drains poorly, if at all, and the rest of the washing drains well, then here it is possible for imbalances to occur only when the spinning cycle has reached higher speeds.

The duration and temperature conditions of automatic washing machine cycles must also be taken into account during the selection of detergent enzymes. These can vary widely from region to region. For example, in Europe, laundry cycles can be more than an hour at temperatures reaching as high as 90°...

Since then, there have been many publications concerning the effect of particles on the formation and stability of foams, froths, and emulsions. Here we are mainly concerned with the destabilizing effect of particles on foams and froths. Practical examples inclnde the effect of hydrophobed mineral particles and collector precipitates on the stability of mineral flotation froths [77, 143], Another is the nse of wax [144] to control the foam of detergent formulations for automatic washing machines. 

It has now been many years since all active substances in detergents were condemned one right after the other. First it was alkyl benzene sulfonates because they foamed. This was followed by sodium tripolyphosphate because it is a nutrient, and then NTA as a result of ignorance and bad data. Within ten years of their introduction the finest detergents ever manufactured were under mortal attack. Before the phosphate detergents there were no satisfactory automatic washing machines. 

The current demand of a circuit is the cument taken by that circuit over a period of time, say, 30 minutes. Some loads make a constant demand all the time they are switched on. A100 watt light bulb will make a constant current demand of (100 watts 230 volts) 0.43 amperes whenever it is switched on. However, an automatic washing machine is made up of a variable speed motor, a pump and a water heater all controlled by a programmer. The washer load will not be constant for the whole time it is switched on, but will vary depending upon the wash cycle. 

The US is the world s largest market for automatic washing machines. Japan is the second largest market, followed by Germany and France.
