Abstract
A rotatable drum forms an airtight seal with a door. A vacuum line connects the interior of the drum to a vacuum pump. A shutoff valve closes the vacuum line to the pump. A pressure equalization valve connects the drum to the outside atmosphere. A bearing supports the drum, in combination with the vacuum line. Infrared lamps heat clothes placed inside the drum. The vacuum pump reduces the air pressure in the drum below atmospheric pressure, reducing the evaporation temperature of the water in the clothes. A heat sensor measures the temperature of the air leaving the drum. Solenoid-driven purge valves allow air to enter the drum in short bursts, thus aiding the drying of the clothes.
Claims10
A clothes dryer for drying wet clothes, wherein the dryer comprises:
- a drum, having an inner surface, an open end for admitting the clothes, and a closed end opposite the open end;
- a door, adapted to close upon the open end of the drum, and forming an airtight seal thereon;
- a bearing, attached to the drum for admitting and connecting a vacuum line to the interior of the drum via an aperture defined in the drum, an airtight seal being formed between the aperture, the bearing, and the vacuum line;
- a vacuum pump, connected to the vacuum line;
- rotating means for rotating the drum;
- heating means for heating the clothes;
- a vacuum shutoff valve, located in the vacuum line between the drum and the vacuum pump;
- and
- a pressure equalization valve, connected to the vacuum line at a point between the drum and the vacuum shutoff valve, for restoring atmospheric pressure inside the drum.
A clothes dryer for drying wet clothes, wherein the dryer comprises:
- a drum, having an inner surface, an open end for admitting the clothes, and a closed end opposite the open end;
- a door, adapted to close upon the open end of the drum, and forming an airtight seal thereon;
- a bearing, attached to the drum for admitting and connecting a vacuum line to the interior of the drum via an aperture defined in the drum, an airtight seal being formed between the aperture, the bearing, and the vacuum line;
- a vacuum pump, connected to the vacuum line;
- a motor;
- a belt, driven by the motor, for rotating the drum;
- infrared lamps for heating the clothes;
- a vacuum shutoff valve, located in the vacuum line between the drum and the vacuum pump;
- and
- a pressure equalization valve, connected to the vacuum line at a point between the drum and the vacuum shutoff valve.
A clothes dryer for drying wet clothes, wherein the dryer comprises:
- a drum, having an inner surface, an open end for admitting the clothes, and a closed end opposite the open end;
- a door, adapted to close upon the open end of the drum, and forming an airtight seal thereon;
- a bearing, attached to the drum;
- a vacuum line connected at one end to the interior of the drum via an aperture defined in the drum, an airtight seal being formed between the aperture and the vacuum line;
- a vacuum pump, connected to the vacuum line;
- a motor;
- a belt, driven by the motor, for rotating the drum;
- a plurality of paddles, attached to the inner surface of the rotating drum, for tumbling the clothes;
- a plurality of diodes, operative in accordance with the Peltier effect, attached to the paddles, the diodes creating heat for heating the clothes;
- a vacuum shutoff valve, located in the vacuum line between the drum and the vacuum pump;
- and
- a pressure equalization valve, connected to the vacuum line at a point between the drum and the vacuum shutoff valve.
