Europe's top consumer electronics show generally showcases gadgets that make life more entertaining with the latest flat screen televisions, stereo equipment and the like.

But this year the Internationale Funkausstellung, opening in Berlin on Friday, will for the first time see usually more down-to-earth appliances like fridges and washing machines fighting for attention.

According to organisers of the six-day show, which hopes to attract more than 200,000 visitors, the inclusion of white goods reflects what they call a "worldwide trend for more comfort in the home and for healthier eating."

And in these days of soaring energy bills and growing environmental consciousness about global warming and water resources, they also offer greater efficiency.

In an effort to boost flagging sales, makers of these normally commonplace home appliances have given them an image revamp, with even the humble vacuum cleaner made to look futuristic and exciting at the Ifa.

But it is not all superficial. There have also been changes under the hoods of many of these products, with mechanical controls ripped out to be replaced by high-tech electronics.

There are "intelligent" washing machines on display from Bosch for example that adapt the amount of water used to the weight of what is being washed, while dishwashers make more efficient use of every last drop.

Fridges just keep things cool, you might think. But no, fridges at the Ifa have in-built LCD televisions and send you a shopping list of what you need -- by email.
