Panasonic, the brand name for which Matsushita Electric Industrial Co., Ltd. is best known, unveiled its tilted-drum washer-dryer that uses no heater or water during the dry cycle. Incorporating a heat-pump dryer for the first time in the world, the NA-VR1000 completes a cycle of washing and drying using half the energy, water and time required for our conventional model. The new model will be available in Japan from November 28, 2005.

Conventional drum-type washer-dryers use heater dryers. During the dry cycle, they consume a large amount of electricity to heat the air and many liters of water to cool the hot air and carry away moisture from the drum. The drying system dries clothes by exchanging heat via heat-pump unit. As it does not let heat or moisture escape outside the dryer drum, it is energy efficient. Reportedly, the drying and moisture removing capability dries garments more quickly. According to the company, three dress shirts will dry in 20 minutes (one-third of the time) and a bulky blanket in 1 1/2 hours (one-half of the time), compared to other conventional dryers.

The NA-VR1000 also features the newly-developed "warm water jet and foam washing system." The warm water jet adds more cleaning power to the foam washing system that is used in the current models. Combined with concentrated detergent foam, it eliminates bacteria and odor more effectively than cold-water washes. Cold-water wash can also be selected according to need. The washing system is included in the tilted-drum washer-dryer models released in China this month.
