Abstract
A convectively air-ventilated furniture comprises an elongated and hollow member having a lower end with an air inlet opening thereat and an upper end with an air exit opening thereat. A massive and elongated convective air channel extends from the air inlet opening to the air exit opening inside the hollow member. The contact areas between the user of the furniture and the top surface of the member are thermally conductive so that the body heat of the user heats up the air inside the hollow member thereby, through chimney effect, initiating and maintaining in the air channel a convective air current directed from the air inlet opening toward the air exit opening and substantially increasing the rate of heat transfer between the user and the air inside the hollow member.
Claims16
A convectively air-ventilated furniture comprising:
- an elongated and hollow member having a lower end and an upper end and having also a top contact surface for the user of the furniture to rest against;
- first wall means defining an air inlet opening at the lower end;
- second wall means defining an air exit opening at the upper end;
- third wall means defining an elongated, convective air channel extending from the air inlet opening to the air exit opening inside the hollow member;
- at least a major portion of the contact area between the user and the top contact surface being air impermeable but sufficiently thermally conductive so that the body heat of the user heats up the air inside the hollow member thereby, through chimney effect, initiating and maintaining in the air channel a significant convective air current directed from the air inlet opening toward the air exit opening and substantially increasing the rate of heat transfer between the user and the air inside the hollow member.
A convectively air-ventilated furniture comprising:

- first wall means defining an air inlet opening at the lower end;
- second wall means defining an air exit opening at the upper end;
- third wall means defining an elongated, convective air channel extending from the air inlet opening to the air exit opening inside the hollow member;
- the contact area between the user and the top surface being sufficiently air-permeable so that the moisture from the user lowers the density of the air inside the hollow member thereby, through chimney effect, initiating and maintaining in the air channel a significant convective air current directed from the air inlet opening toward the air exit opening and substantially increasing the rate of moisture removal from the user into the convective air current, the non-contacted area of the top surface being air-tight to avoid air communication therethrough thereby enhancing the strength of the convective air current.
