  • Patent number: 8668765
    Abstract: A drying system includes a desiccant wheel that dries incoming air. The dried air is heated using a heating element to promote drying of an article within the drying system. A portion of the heated air is diverted to a secondary air path that leads away from the drum holding the article. The diverted portion is used to regenerate an area of the desiccant wheel. A secondary heating element is used to promote regeneration and located in the secondary air path.
    Type: Grant

  • Patent number: 8137440
    Abstract: A dryer and a drying apparatus attachable to a dryer are disclosed. A wheel having desiccant material is located in line and in close proximity with a heating element. The wheel includes a first portion positioned in an inlet air path and a second portion positioned in an outlet air path. The desiccant material removes water molecules from air within the inlet air path, and lowers the vapor pressure of the incoming air. In the outlet air path, heated air flows through the second portion to transfer energy to the desiccant material. The wheel rotates to change the desiccant material within the portions.

  • Publication number: 20090205220
    Abstract: An adapter to a dryer, or a new configuration to a dryer, allows articles, such as clothes, towels, sheets and the like to dry with reduced energy consumption. The adapted configuration draws air from outside the room or structure housing the dryer. The outside air is then used to dry the articles. The outside air can be heated within the dryer using the existing heater prior to entering the drum holding the articles. After the heated air removes moisture from the articles, the moist, hot air is expelled outside the room or structure through an outlet air duct. Thus, air within the room or structure is not used for the drying process and conditions such as temperature and pressure are not changed when the dryer is on.
