Bed compromising an air guiding unit for air-conditioning rooms
View Patent ↗The invention being submitted pertains to a bed, consisting of a bedstead ( 1 ) and a mattress ( 2 ), whereby an air-conduction unit ( 4 ) is integrated in the bedstead. Along one or more lateral walls ( 3 ) of the bedstead ( 3 ), side ducts ( 6 ) are provided with lateral escape ports ( 5 ) for the out-flow of air from the air-conduction unit ( 4 ). Additionally, a mattress air-chamber ( 10 ) is provided with the upper escape ports ( 8 ) for the discharge of air from the air-conduction unit ( 4 ).
1. Bed comprised of a bedstead and a mattress, wherein the bedstead has side-walls and comprises an air-conduction unit and the air-conduction unit comprises the side-walls, the side-walls having openings therethrough for the passage of air, said openings comprise escape ports in the side-walls for lateral outflow of air out of the bedstead from the air-conduction unit, further comprising:
side-ducts in the air-conduction unit, the side-ducts being comprised of the side-walls having escape-ports; and
an air-chamber formed in the bedstead, the air-chamber communicating with upper escape ports; and
a side-duct feeding connection for feeding air into the side-ducts, means sealing the side-ducts so that the air fed thereto can escape only through said escape ports; and
a mattress-rack for supporting the mattress and, beneath the mattress rack, a topside having upper escape ports for the passage of air; and
means sealing the air-chamber so that air therefrom can escape only through said upper escape ports; and
further comprising an additional air connection for communication between a source of conditioned air and the side-ducts and/or the air-chamber.
2. Bed according to claim 1 , further comprising a disinfectant dispenser for dispensing disinfectant into the air-chamber.
3. Bed according to claim 1 , further comprising means separating and sealing the air-chamber from the side-ducts.
4. Bed according to claim 1 , wherein the bedstead further comprises a distribution-chamber and feed-lines communicating between the distribution-chamber and the side-ducts and the air-chamber.
5. Bed according to claim 1 , further comprising at least one sliding flap for selectively blocking communication between the distribution-chamber and the side-ducts and the air-chamber.
6. Bed according to claim 1 , further comprising at least one chamber-plate in the air-chamber, the chamber-plates having adjustable individual jets or distribution-bars.
7. Bed according to claim 1 , further comprising a switchover unit which alternately opens and/or closes communication between the distribution-chamber and the side-ducts and the air-chamber.
8. Bed according to claim 1 , further comprising means for detecting presence of a person in a room in which the bed is located and for controlling the switchover unit by signaling said presence of a person.
9. Bed according to claim 1 , further comprising a manual switch for operating the switchover unit.
10. Bed according to claim 1 , further comprising additional bedstead walls sealingly engaging at least a portion of a periphery of the mattress.
11. Bed according to claim 1 , wherein at least some of the escape ports comprise nozzles.
12. Bed according to claim 1 , in combination wit a source of conditioned air, the conditioned are being cooled or warmed.
13. Bad according to claim 12 , wherein the source of conditioned air is accommodated in the distribution-chambers.
14. Bed according to claim 1 , further comprising means for connecting the additional air-connection to a central air cooling and/or heating system.
15. Bed according to claim 1 , wherein the mattress is air-permeable.
16. Bed according to claim 1 , further comprising conduits integrated into the mattress for conducting air from the upper escape ports only vertically into the mattress.
17. Bed according to claim 1 , wherein the mattress is of a honeycomb structure.
18. A wet-cell installation for a room, comprising;
partition walls and a ceiling and an air-treatment unit contained in the installation and air-conditioning ducts mounted in flue walls and communicating with the air-treatment unit, said air-treatment unit is mounted in the ceiling; and
means for sensing room-air temperature and, in response thereto, controlling the air-treatment unit, said air-treatment unit further comprises means for dispensing disinfectant into air being treated; and
an additional air duct adapted to supply conditioned fresh-air from the air-treatment unit to an air-connection of a receiver of the conditioned fresh-air;
said wet-cell installation in combination with a bed comprising a bedstead and a mattress, the bedstead comprising an air-chamber and air-ducts and including said air-connection, said air-connection communicating with the bedstead air-chambers and air-ducts.
