sorry to post this but I am curios to know...

[aquarius8000]

...The LG dryers, do they have an inverter direct drive motor, and how do dryers use steam to dry clothes when steam is a vapourised liquid?

P.s, this may come in handy soon!

Again, sorry for posting this but I have allways wanted to know.

Help appreciated,

Chris.

Don't understand why you are so apologetic about posting what seems to me to be a perfectly valid question. The fact that I haven't got a clue what you are talking about is beside the point - fair point, well made LOL!!

Steam is not used for drying; it is used for de-wrinkling, sanitizing/anti-allergy and stopping static cling, depending on how the particular brand is marketing it.

Just a few people dont like us youngsters posting here.

Thanks Peter

That is utter rubbish, and you know it. The reason people have been so hard on you lately is due to the increased volume of pointless threads and posts that use this forum like an instant messenger service and not a forum, all created by the same bunch of people. You're age has NOTHING to do with it - if you were 65 we'd still be saying the same thing! As I've previously said, it's just plain daft to post "I've e-mailed you" to your mate and it wastes valuable web space that could be used for something worth posting.

Questions like this are exactly what this forum is for

Ok.

Sorry about that 'ive emaild you' situation. Lets put it in the past please.

Again thanks for you end comment, has put a smile on my face.

^Agreed. These kind of posts are great. I often find somebody will ask a question, maybe not one I need to know, but the answer is still interesting because it adds to my knowledge.

I certainly hope someone can help. Sorry, but I know nothing about LG dryers - only ever used the washers.

 

[aquarius8000]

cant be helped that you dont know that but atleast it will give you more knowlige too.

As above, the steam is largely to release wrinkles. Rather than pay $200 extra for a steam dryer, I'd pay $1 for a spray bottle. But that's just me.

As for inverter drive, I don't know the specifics of any model. It's never specifically published. Example, there's a "direct drive" Whirlpool topload washer, but obviously the motor is not attached DIRECTLY to the agitator, as in, no intervening mechanism.

It is possible--though questionably practical--to make a LITERAL direct drive frontload washer, with curved linear-motor segments. It's even less practical in a dryer, which only needs to run one speed and one direction. And where the energy consumption is on the order of 30:1 heat:motor.

My Frigiwhite FL is not inverter, it's chopper. That is, mains AC is (either synchronously or asynchronously) chopped to PWM DC. Then the motor is 'directly' coupled to the drum by a reduction pulley. Thus it changes both speed and direction entirely electronically. The only remaining mechanical wear point other than the belt is the brushes. Inverter does away with those. But the inverter electronics is about 3 times as complicated, and evidence suggests that electronics is a weak point in electronic washers. Thus inverter is ~3x more prone to failure than chopper, whereas brushes are very cheap and easily replaced.

electronic controlled motors

my '98 frigilux and '02 splendide both use brushed PWM driven DC motors-when i had
the very well used frigilux apart for a bearing repair,i checked the brush length
and they were still quite long-should last the life of the washer in most cases.
my '98 mah 3000 neptune is driven by a"switched reluctance"electronic driven motor
-it's basicly a big stepper motor(makes some cool"UFO liftoff"sounds during spin
runnup!)
my '09 GE hydrowave has a 3phase induction motor driven by an inverter to provide
the agitation motion and to allow the induction motor to run at around 10,000 rpm
during spin-there is no transmission between the pulley the motor drives and the
agitator,the motor just reverses back and forth during agitation.For spin a
magnetic dog clutch locks the tub to the agitator shaft-at start of spin motor
creeps at low speed to make sure clutch is locked and tub turns freely then winds
up to spin speed.

me i would not rely on steam the best way to avoid wrinkle and i am the one doing the washing in my family is to 1 wash the shirt in cold water at the perm press casual cycle and 2 to hang dry the shirt and not put it in the dryer.

Thanks for the information guys....

How do dryers make the steam, does it make the energy bill rise and what type of dryers is it on?(vented or condensor?)

Thanks,

Chris

 

[iheartmaytag]

I can only speak of what I am familiar

How the dryer makes steam.

My Maytag 5000 series has a small spray nozzle, more of a mister,  in the back of the drum.  This mister is attached to a Y couple from the cold water inlet shared with the washer.    On a steam cycle the dryer will run at high temp for about 5 minutes before the mister sprays for approximately 1 minute.  Then, depending on the cycle, the dryer runs for an additional set time 10 - 25 minutes to dry the clothes and lets you know they are finished.

 

Sorry, came back to answer the other questions you had. 

My dryer is vented.

As for the energy used, I am sure it increases the usage some, but I use the cycle so infrequently; it isn't noticable.

LG Steam Dryer

Has a reservoir that you fill with water, as you would a steam iron.  The unit has a heater that will make the steam and it is released to the cylinder automatically according to your cycle choice.  I've seen it demo'd, I still think it's just a gimmick.

Who are we to judge if your question is valid or not? For you it's a relevant question, for others it may not be so relevant, but It doesn't means it's not a valid question and you don't need to apologize.

As said above, the steam is not used to "dry" the clothes, but to remove wrinkles.

Also, as said above, it's all about marketing and how to get some extra money from consumer's wallets.
Steam works and really helps removing wrinkles, but nobody needs to spend a lot of money to do that. You can spray the clothes using a $1 spray bottle or don't spend a single cent and get an old silk scarf or a napkin or any small piece of thin fabric, soak it with water, squeeze with your hand and put it in the drum together with the clothes.

I don't know if the dryer has a "direct drive" motor, but this kind of motor is made only to reduce production costs (and make the consumers believe it's better)

These motors are as reliable as an standard motor but, if there's a failure, it's a nightmare to be fixed (nightmare to the consumers). and a wonderful dream to manufacturers. The worst case scenario is a worn belt... only $5 or less to replace
and the smallest malfuncion in a DD motor means the whole motor has to be replaced.

For those who like the spin noise (that's my case) there's only a small difference on the tone. a standard motor sounds like a jet engine, while the DD sounds like the subway. DD motor are less than 5db more silent than other motors. unless your ears are so sensitive that can hear a butterfly farting, you won't hear any diference on noise level.

I see no reason (unless profit) to have a DD motor in a dryer.

Here in Brazil Electrolux tried to use this DD "pancake" motor in a standard top loading machine. The market HATED it. (but electrolux loved it because the machine has no transmission, only a small magnetic clutch and costed 50% more only because of the DD marketing.)
