Spin dryer drum design

[adam-aussie-vac]

Hey guys what is a better drum for extracting the water out of laundry? Would that be

A: A spin dryer drum with holes/slots at the top?
B: A spin dryer drum with holes/slots at the bottom?
C A spin dryer drum with holes / slots all over?

Photos 1,2 and 3 Correspond to questions A,B and C

As with washer/extractors suds containers with holes give better results for spin drying than those with merely "slits", and other variations of solid tub designs.

IIRC Creda and some other spin driers used those nearly solid inner tub design (slits around center and top of tub), because machines could be used for rinsing well as extraction. Without holes water poured into spin can largely remained soaking into wash.

IIRC some early front load washing machines sold in Europe had small slits instead of holes in suds containers. Don't believe that design lasted very long, but am not sure.

Now of course Miele with their whole "honeycomb" suds container design has taken things to next level. Suds container has quite small holes which means machine uses less water for washing and rinsing because less of it goes between suds container and outer tub.

Would you mind telling me what the suds container is

I actually don’t know what that is

Whats Better ?

Hi Adam, No one drum gives better water extraction just on holes alone, it also depends on drum container diameter, motor torque and rotating speed.

The UK are probably the only country that has used all the various types of spin dryers / extractors / wizzors both domestic and commercial.

Holy Drums: will give the quickest route for the water to be flung out of the clothes, but size of holes determines clothes getting stuck in the holes blocking routes for the rest of the clothing to dry, and gives you all those dimples etc that you have to peel the clothes out of the holes possibly damaging them.

Examples are: Hoover & Creda[this post was last edited: 9/12/2021-04:57]

What Spin Drum Is Best

Solid Spin Drums where developed for twin tub combination washing machines and where great for rinsing in the spin can, water can be poured or sprayed on or over and through the clothes then when the centrifugal forces start the water is spun through the clothes and out of holes or vanes at the top or lower part of the spin can.Examples are early Servis Twin Tubs and Hotpoint.

Which Spin Can Is Best ?

Single Vane Extraction Drums: Many spin dryers had solid type spin cans made of either metal , aluminium or vitreous enamel, these where typically a solid can with a single vane in the middle of the drum and a lip at the top through which the water would be spun through or over .Typically Creda , Frigidaire and later Servis drums.

Which Spin Drum Is Best For Extraction ?

Servis UK the only British manufacturer of washing machines from 1929 where the first to introduce the "Spin-Care" range of drums into the worlds first computer controlled washing machines. They basically turned the spin can with vanes onto its side, the extra water retained in the drum cushioned the clothes, retained more water in the wash drum and then upon draining and spinning the water extracted through the vanes situated in the front & back of the wash drum.

Suds container - inner wash tub.

Have Miele on mind I guess after a night of doing research. It's what Miele calls inner wash tubs on their machines.

"The newly designed suds container closely hugs the inner drum, and the entrance to the sump with its heater elements is gently curved"

So, "suds container" means the Outer Tub and the thing that revolves is the "inner drum" in Miele`s strange kind of wording.

Or am I missing something?

Had things muddled...

Just checked parts diagram for my Miele washer...

Suds container is the outer tub.

Inner tub is called "drum".

So that's me for you, always holding fuzzy end of lollipop.

 

[mrboilwash]

I don`t know exactly what always holding fuzzy end of lollipop means but I hope you didn`t take it personally that I corrected you.

 

[launderess]

Not you, but us.

Meant once again one had things muddled. Nothing directed towards your good self.

Good info, good explanation.

Thanks, Chestermike.

Kind regards, Walter.
