Abstract

A system for adjusting the microclimate of a bed environment includes a multi-zone mattress-style support having individual heating zones, a heater for heating the individual heating zones, a cooler for cooling the multi-zone mattress-style support, and temperature sensors. The cooler includes the multi-zone mattress-style support at least one air duct with the multi-zone mattress-style support for transporting ambient air through the multi-zone mattress-style support.

First claim

The invention claimed is:

1. A system for adjusting the microclimate of a bed environment, the system comprising:
multi-zone mattress-style support including a plurality of individual heating zones;
means for heating the plurality of individual heating zones;
means for cooling the multi-zone mattress-style support; and
a plurality of temperature sensors, and
wherein the means for cooling the multi-zone mattress-style support comprises at least one air duct, within the multi-zone mattress-style support, for transporting ambient air through the multi-zone mattress-style support, the at least one air duct comprising at least one inlet opening for receiving air and at least one outlet opening for output of the air,
wherein the at least one air duct includes a plurality of longitudinally extending air ducts adjacent to each other and parallel to a longitudinal axis of the multi-zone mattress-style support, the adjacent air ducts being configured to transport air in opposite directions, and each of the adjacent air ducts having respective inlet and outlet openings of the at least one inlet opening and the at least one outlet opening, and
wherein the at least one inlet opening of the at least one air duct is at a first side end of the at least one air duct for receiving the air along a longitudinal direction parallel to the longitudinal axis, and the at least one outlet opening of the at least one air duct is at a second side end of the at least one air duct for output of the air along the longitudinal direction, the first side end and the second side end being at opposite side ends of the at least one air duct.

2. The system according to claim 1 , wherein the plurality of individual heating zones is configured to be heated individually.

3. The system according to claim 1 , wherein the means for cooling further comprises at least one lowering means for lowering the air temperature below the temperature of the ambient air, said lowering means being selected from the group consisting of Peltier elements and cooling compressor units.

4. The system according to claim 1 , wherein the means for cooling the multi-zone mattress-style support does not comprise any means for cooling the air to a temperature which is lower than the temperature of the ambient air.

5. The system according to claim 1 , wherein each heating zone of the plurality of individual heating zones is provided with at least one temperature sensor of the plurality of temperature sensors.

6. The system according to claim 4 , further comprising at least one additional temperature sensor for sensing the temperature of a room where the system is located.

7. The system according to 1 , further comprising a controller operatively connected with the temperature sensors, the means for heating the plurality of individual heating zones, and the means for cooling the multi-zone mattress-style support.

8. The system according to 1 , wherein the multi-zone mattress-style support is a mattress positionable directly on a slatted frame or a box spring, or is a topper mattress that can be laid on top of a mattress.

9. The system according to claim 1 , wherein the at least one air duct comprises a plurality of air ducts with outlet openings arranged facing an upper face of the multi-zone mattress-style support.

10. The system according claim 1 , wherein the at least one air duct comprises a plurality of air ducts with outlet openings, the outlet openings being arranged to a side of the multi-zone mattress-style support for preventing air to enter the bed and creating an air flow in a plane of the multi-zone mattress-style support.

11. The system according to claim 1 , wherein the least one air duct includes a plurality of air ducts configured to provide individual zones that can be cooled independently of one another.

12. Use of a system as defined in claim 1 for adjusting the microclimate of a bed environment.

13. A method for adjusting the microclimate of a bed environment, the method comprising acts of:
measuring temperature of the bed environment in individual zones; and
adjusting the temperature of the bed environment in the individual zones such that the temperature in said individual zones is kept at a preset temperature,
wherein the adjusting act includes an act of warming by a heater or cooling by a cooler the individual zones to the preset temperature, the cooler having at least one air duct comprising at least one inlet opening and at least one outlet opening,
wherein the warming act includes an act of subjecting at least one electrical resistance wire in each individual heating zone of a multi-zone mattress-style support to an electric current thereby becoming warm, wherein the warmth is conducted from the electrical resistance to an upper face of the multi-zone mattress-style support by conduction,
wherein the cooling act includes an act of forcing air to flow through the at least one air duct within the multi-zone mattress-style support,
wherein the at least one air duct includes a plurality of air ducts adjacent to each other and parallel to a longitudinal axis of the multi-zone mattress-style support, the adjacent air ducts being configured to transport air in opposite directions, and each of the adjacent air ducts having respective inlet and outlet openings of the at least one inlet opening and the at least one outlet opening, and
wherein the at least one inlet opening of the at least one air duct of the respective inlet and outlet openings is at a first side end of the air duct for receiving the air along a longitudinal direction parallel to the longitudinal axis, and the at least one outlet opening of the at least one air duct is at a second side end of the at least one air duct for output of the air along the longitudinal direction, the first side end and the second side end being at opposite side ends of the at least one air duct.

14. The method according to claim 13 , wherein temperature of the at least one air that is forced through the at least one air duct within the multi-zone mattress-style support is not lowered below temperature of ambient air.

15. The method according to claim 13 , wherein temperature of the air that is forced through the at least one air duct within the multi-zone mattress-style support is lowered below temperature of ambient air.

16. A system for adjusting the microclimate of a bed environment, the system comprising:
a multi-zone mattress-style support including a plurality of individual heating zones;
a heater configured to heat the individual heating zones;
a cooler configured to cool the multi-zone mattress-style support; and
a plurality of temperature sensors,
wherein the cooler comprises at least one air duct, within the multi-zone mattress-style support, for transporting ambient air through the multi-zone mattress-style support, the at least one air duct comprising at least one inlet opening for receiving air and at least one outlet opening for output of air to the multi-zone mattress-style support,
wherein the at least one air duct includes a plurality of air ducts adjacent to each other and parallel to a longitudinal axis of the multi-zone mattress-style support, the adjacent air ducts being configured to transport air in opposite directions, and each of the adjacent air ducts having respective inlet and outlet opening of the at least one inlet opening and the at least one outlet opening, and
wherein the at least one inlet opening of the at least one air duct is at a first side end of the at least one air duct for receiving the air along a longitudinal direction parallel to the longitudinal axi
