Askomiele has posted in another thread a brochure of a Kannegiesser.de tunnel washer matched with a spray rinsing spin dryer .

He thinks (me too) this could work on frontloaders too.
Sudslocks are the main issue. Maybe this thing could work : a very low spin speed (e.g 200 rpm) while spraying fresh water with a pressure booster, then a progressive increase up to 1000 rpm without spray action, both alternated several times, then one final normal rinse with eventual FS .

The spray booster is required to produce a lot of mist rather than a plain jet (...this is E'lux Jetsystem, the jet reaches only those clothes close to the glass door)

A question : how do US toploaders avoid sudslocks during the first sprayrinse after the mainwash ? It's about spin speed or has it to do with the gap between inner and outer tub ?

Any comment or ideas are welcome

Thanks

I reckon...

....the following would probably work

- a very low level first rinse
- high speed spin - say 1200 rpm
- slow to distribution speed (machine is already balanced)
- followed by a spray rinse at distribution speed
- ramp to 1200rpm
- repeat
- final low level fabric softener rinse

Mind, with the amount of water that would be used in the spin rinse, you could just have 3 low level rinses. Provided there is a high speed extraction between each one, they should be fine....

If memory serves, F&P machines do a spin spray rinse by default. Only adding a deep rinse if softener option is enabled.

...top load machines on our market have different cycles.

- an eco option does spray rinses only
- traditional rinse does spray and deep rinse (which by default allows conditioner to be used)
 
Unimac Twin Tubs

Have a spray rinse as the only rinse option, unless one wishes to move the laundry back to the wash tub for a "deep rinse".

Extractor tubs on Unimac twin tubs looks quite like those on vintage Easy SpinDrier's with the center post that has small holes. While the tub spins slowly, a fine mist of water is sprayed at wash, which gets pulled through and spun out. The spray stops and extractor cranks up to full speed to spin out the water. This goes one several times then the final high speed spin to extract water.

Problem with some top loader's spray rinse features, both then and now is either they were designed so water barely reached laundry, and or was bounced off same because of too high rpm speed did not allow water to penetrate the wash.
 
The Brazilian electrolux washers have this combination of ramps and jets.

the jets are also intermitent, so there's some time to drain the water and avoid a sudslock.

there's a TOL model (Acquajet) that has an injector just like the WCI westinghouse top loaders aimed straight to the clothes and is also has an eco rinse option.

the other models were designed to allow the water cascade falling from the dispenser drawer, hit the bottom of the agitator and be sprayed all over the drum by the agitator fins, just like a dishwasher. (it also helps rinsing the glass lid and the agitator's top.

They also have what we call SLC (in portuguese Basket Cleaning System) that has another water jet aiming the outer part of the tub and a small brush scrubs it during the beginning of every spin cycle (rinse spins and final spin). It reduces a lot the build ups caused by our too sudsy detergents.

After the spin rinse, it's sure there's no trace of detergent on the clothes or the tub.
 
Question:

I am wondering: Why do they make high sudsing detergents in South America? What would be their advantage over the low sudsing HE detergents like what we have in the United States?

Answer one: Because the brazilian consumers believe that "if it doesn't fill my house up to the roof with foam, it won't clean".

Omo, the #1 brand here in brazil is much more sudsy than regular Tide.

------------------

They are not so noisy. One can hear the water falling and spraying, but it isn't loud enough to be irritant.

I think the most irritant about those machines is the interlock brake. One can hear it's "click-bang" blocks away.

I always know when my neighbours that have "not so new" Electrolux washers are doing their laundry.

I have one of those in my collection, I'll try to make a video when I use it again and post it here.
 
Haha thx favorit...

Apparantly the 'kannegiesser' technology is new and performes good! Well you read my mind. I was thinking about saving on rinse water and using it to wash properly during mainwash! The machine would spin out the wash water and slow down to a certain rpm where the clothes just 'spinning' around and not really pressed against the wall. There should be a jet that covers the whole wall of the drum to saturate the washing and when the machine detects the clothes are saturated the machine would speed up again. Because the machine needs to break and speed up a lot would this cause more wear on the motor? Maybe it's a good idea to use a directdrivesystem for this...
 
I`m wondering if an effective sprayrinse would be possible at all in a frontloader without a center post keeping the center clear of laundry in the spincycle. Large items like sheets sometimes tend to span over the center in a frontloader and I`m thinking that would block most of the spray maybe even if it`s high pressure and slow revolution. A laser beam in the door boot and a mirror in the center of the drum`s backplane might help balancing properly.
 
Thomas, just think of turbidity sensors in dishwashers.
They work in a very similar way and cost only a few extra "cents". Nothing upscale about them at all...

If the beam detects a sheet or something bulky like a pillow in the way of the water jet the machine could redistribute the load and if that fails as well, a traditional rinse would still be an option.

Perhaps I should apply for a Patent *LOL*

The Brazilian washers you mentioned are toploaders with a center post agitator, right ?
 
a "new old" idea : "intervallspuelschleudern&

Maybe a graduate spray rinse spin routine could bypass the "sheet issue", avoid sudslocks, enhance rinse performance and obviously reduce wrinkles:

1) distribution and spray rinse @ low speed ( e.g.45 seconds)
2) ramp up to hi speed (hold time 30 seconds)
3) loose coast stop (no brake = no stress)
4) some reverse tumbles (clothes change place : less creases , better rinse even if the centre issue is repeated)
5) repeat 1>>4( e.g. four times)
