Washing machine life profile
Dear, First, i have seen on FIDES 2009, there are 1 more rinse in the table of phases by program (§3.5.3) than in the principle of life profile (§3.5.1). •17 "fragile washing" cycles/year, with 2 rinses / cycle (1 rinse/cycle in §3.5.1) •100 "normal programs" cycles/year, with 3 rinses / cycle (2 rinses/cycle in §3.5.1) •33 "very dirty" cycles/year, with 3 rinses / cycle (2 rinses/cycle in §3.5.1) Total = 150 cycles = 433 rinses / year What is this additional rinse? It’s a preliminary rinse at 18°C before washing clothes (before programs)? Secondly, in the "very dirty" program in table of phases (§3.5.3), there are 2 phases of washing with drum at 80°C (Short wash and Normal wash). Each phase have 33 cycles/ year so 66 cycles / year in total (together). Same for the "Empty (drum at 80°C) phase" = 66 cycles. 66 cycles of “washing and empty” with drum at 80°C, but there are only 33 cycles/year of "Heating to 80°C". The same cycle of heating is used for the 2 phases of washing with drum at 80°C (short wash and normal wash). •Duration of washing (short and normal) + empty = 0.13 + 0.33 + 0.1 = 0.56 hours/very dirty cycle •During of heating = 0.26 hours/very dirty cycle The drum of washing machine can have the same temperature between 2 washes without another heating?

Re: Washing machine life profile

Dear,

Thank you and congatulation for your message. You have exactly understood the purpose of the life profile examples in the FIDES Guide 2009: to show principles and to be analysed, and not to be used as it.

I have not look in details in your question for the moment. The washing machine life profile illustrates how it is possible to go from the functional description of the product to the life profile. The firts step (§3.5.1) is what is known at user level. It was not possible to put all the reasonning in the FIDES Guide. So it doesn′t show for example that each spin includes a rinse (fact that explains your first question). We will look further later the details of your remark.

Thank you again for this first contribution to FIDES Guide 2009!

All the best with FIDES!
