Drying times? washer-dryer combo

""The drying system doesn't use a total condenser (it has a dry condenser that doesn't use water to cool down)"

I'd think this'd be a major selling point: You could use the dryer anywhere there's an outlet.

My comments about flood pans, discharge rates, etc. were for would-be buyers whose landlords or co-op boards are hysterical about the building being "not able to handle" washers. It would probably be a selling point if the washer could use "dishwasher connections" The point is not the actual physics of the situation. The point is for buyers to have some sort of evidence to prove that if the building can handle a dishwasher, it can handle your washer.

Is there a possibility of a water heater and of warm rinses? It'd be another selling point if the owner would still be able to laundry even if the hot water were out (remember, many customers would live in old apartment buildings). I'd suspect most buyers would be happy to accept the longer wash times that would result. The prime concern would be for their schedule not to be disrupted. "

Pans: impossible

Draining: It drains slower than a dishwasher. It's almost like a dishwasher draininb with pauses.

It has a built in water heater and it is cold fill only.
Warm rinses, unfortunately no.

It also has delay start and user friendly (user selects the time to end the cycle and the washer calculates the delay based on the lenght of the cycle)

Modern European machines have built in flood pans, the bottom of the machine has that function, so it's doable. It's part of a water safety system, including a cut off of the water supply when the bottom of the machine gets flooded.

The molds already exist, it's impossible to make new molds because the cost is absurd.

I've always thought about incorporating a conventional dryer system into a front load washer platform. That is, having a submersible heating element around the back of the outer drum, in a similar manner of how GE and Frigidaire constructs their dryers (albeit, the elements are exposed nichrome and would NOT be a good mix around water!). This element could also heat water during the wash cycle. As for venting, a duct at the top of the outer drum connects to a small centrifugal blower, separated by a lint screen which is pulled up at the top.

As for the vanes in the drum, they would need to be deeper than what is typical in domestic FLs so that the laundry tumbles well as it should in a conventional dryer. I would imagine that deeper vanes would enhance wash performance as well.

I don't know how a gas-powered dry system would be incorporated into a FL, though. It would have to be heat exchanger tubes surrounding the outer drum.

The issue with the dryer element being placed in the tub is the radiant heat. Radiant heat of a sufficently powerfull element will mean the SS drum heats up like a skillet and scorches clothing.
See the drying temperatures of the GE units.

Dryers with exposed wire elements never have the elements in direct line of sight to the laundry, and in general, no current system I know of has. Thus, no radiant heat is implied to the laundry.

A gas combo would just as any gas dryer have a burner assembly seperate from the wash tub with some kind of splash guard and air path to the tub.
The is a video of a gas combo on YouTube that explains that pretty well.
