Introduction New Dryer Platforms

ENV 06 will substitute all the electronic and timer plattforms fortumble dryers.

The substitution involves:

-EDR 1000-EDR 2000- All dryers with mechanical Timers

All user interfaces will be substituted too.

Introduction: August / September 2006

Product Definition

Requirements on performance:

Drying (condensation)- Drying performance are identical to condensation dryer running production 2006- Programme technique, load capacity, no. of drying programmes identical to condensation dryer running production 2006

Real Wool Drying- Suitable for all kind of articles which are sensitive against mechanical agitation (wool, viscose, ... )- For reduced amount of load (1 ... 2 kg)

10

Product Definition

• Clothes refreshing- odour removal procedure with steam or/and fragrance

treatment- textile surface refreshment with steam treatment for cotton, fleece, linen fabrics etc.

- variable process air circuit (switch from open to closed position automatically depending on process step)

• De-wrinkling procedure- very improved easy ironing performance for cotton compared to the existing easy ironing program

- steam treatment for cotton fabrics- improved temperature – mechanic – profile for synthetics

Product Definition - Performance

As a function of material, quantity and programme

– Pre-ironing -> for blouses, shirts, trousers , jackets, skirts, coats etc. from linen, cotton, synthetic for 0,5 to ca. 1 kg laundry, that do not have to be ironed in ideal case

– Refresh -> Usable with not-washable and not washed textiles, Removing of smells, folds and rough creases - possibly is later necessary a ironing, since e.g. also „Bügelfalten“ are removed

– Iron aid -> for all materials because relatively even moisture distribution on and in the materials for 0,5 to ca. 3 kg laundry

Air Ccirculation System

The drying functionality is influenced by two air circulationsystems.• a warm air circuit which is sealed within the appliance• a cold air circuit which circulates ambient air through certain sections of the appliance

The warm air circuit removes the humidity from the clothes fabrics and crosses the cold air circuit inside of the heat exchanger. The result is a thermal exchange which condenses the humidity contained in the warm air.The condensation water is collected in a tank.

18

Humidity Sensing

Conductimetric sensor:

The two halves of the drum are separated by an insulating strip.The impedance of the front and rear shells ( to which the sensorsare connected) varies according tothe wash load, the type of fabricand the degree of humidity.This value is converted into anoscillation of 260Hz and 0Hz bythe electronic.It determines the duration ofthe cycle and the final humidity.

To create a sufficient air flow it is necessary to haveindependend drum and fan motors.

During the steam programmes the steam should stay in the drum. no air circulation but drum movement no fan

4. For graphic LCD user interfaces (TC1) a specific customer screen with complete alarm code and possible supplemen-tary text descriptions can be shown

5. Delete the alarm memory by pressing standard key combination

65

Alarm Management In Service Mode

Attention:

It´s possible to read the last three alarm codes in the alarm memory by pressing a key combination simultaneously.

( Solution still under development )

66

Clear Alarm Memory

The alarm memory can be cleaned in service mode. Use thestandard key combination for 2 seconds in the alarm memory position of the programme selector

Important! After a succesful repair the alarm memory should becleared always.

Standard key combination:Press simoultaneously Start/Pause and the first key left from it.

67

Alarm Table

The failure codes of the EDR1000 / EDR 2000 range are stillvalid.Additionally new alarm codes will be implemented for the CRMcomponents.

The creation of the new alarm table is still in development.

It can be found in the new service manuals for the ENV06

Tumble dryer models when available.
