Washer-dryer
A combi washer dryer (also known as a washer-dryer in the UK) is a combination in a single cabinet of a washing machine and a clothes dryer. It should not be confused with a "stacked" combination of a separate autowasher and a separate tumble dryer.
The small size of these machines, compared to the total space consumed by a separate autowasher and tumble dryer, suits them to small homes, apartments, and condominiums. Combo units typically have a small height, allowing them to fit into confined places. The units are notable for their ability to wash and dry clothes in a single cycle without the need to transfer laundry between two machines.
Aside from the early wringer/washer machine of the mid-19th century, washing and drying machines were not combined until the latter half of the 20th century. The first completely automatic clothes washer was developed by Bendix Home Appliances in 1937; the same company also invented the first washer-dryer combination unit in 1953.
Most washer-dryers are of the front-loading design for easier access, better efficiency, and more effective washes. Instead of just leaving the clothes to soak in the water throughout the entire wash, like a top-loading machine would do, the front-loading design rotates the drum along its longitudinal axis, so that the contents of the drum are repeatedly lifted in and out of the water throughout the wash cycle.
Most washer dryer combi's are ventless and are designed with drying systems that work differently from the ordinary stand-alone (vented) dryer. Instead of venting moist hot air to the outside, like a conventional dryer would, the combo unit makes use of condensation similarly to condenser dryers. Hot dry(er) air enters the drum from either the front or the rear, and evaporates some of the moisture from the tumbling clothing. This warm, damp air is then drawn through a condensing chamber, and the extracted water is flushed out the drain hose to the sink or through the plumbing lines. These units can be installed under cabinets, in cupboards or anywhere with electricity.
Typically in separate condenser dryers, cool air is used to cool down the process air from the inside drum and to condense the vapor. In combined washer dryers, however, cold water is used instead. The water flows in the opposite direction to the air, allowing the air to cool and to release its moisture, which is pumped out along with the water used to cool the air. These machines normally take longer than regular dryers, because the combo unit has a smaller drum, so there is less volume to allow air circulation and the drum itself must be dried immediately after a wash cycle. This water-fed drying system consumes water for both the washing and drying phases of operation, and may not be suitable for areas where water is scarce.
Alternative methods of cooling the condenser have emerged.
Since condensing dryers discharge waste heat inside buildings, they may increase air conditioning heat loads in summer or provide useful heat in winter. Energy and water usage must be evaluated for the entire system over the entire year to ensure a valid comparison.
