Abstract

According to certain arrangements, a climate controlled bed includes an upper portion comprising a core with a top core surface and a bottom core surface. The core includes at least one passageway extending from the top core surface to the bottom core surface. The upper portion of the bed further includes at least one fluid distribution member positioned above the core, wherein the fluid distribution member is in fluid communication with at least one passageway of the core. The fluid distribution member is configured to at least partially distribute fluid within said fluid distribution member.

First claim

What is claimed is:

1. A climate controlled bed comprising:
an upper portion having a top surface and a bottom surface, wherein the upper portion comprises at least one fluid distribution member;
a fluid module comprising a fluid transfer device and a thermal conditioning device that selectively heats or cools fluid entering the fluid module;
at least one fluid passageway placing the at least one fluid distribution member in fluid communication with the fluid module;
at least one humidity sensor positioned along or near an inlet of the fluid module and configured to measure a humidity of fluid entering the fluid module; and
a control unit operatively coupled to the at least one humidity sensor and the fluid module, wherein the control unit is configured, based at least in part on the humidity measured by the humidity sensor to modify at least one operational parameter of the thermal conditioning device in order to reduce the likelihood of condensation formation by the fluid module.

2. The climate controlled bed of claim 1 , wherein the thermal conditioning device comprises a thermoelectric device.

3. The climate controlled bed of claim 1 , wherein the at least one fluid distribution member comprises a spacer fabric or other spacer material.

4. The climate controlled bed of claim 1 , wherein the upper portion comprises a mattress.

5. The climate controlled bed of claim 1 , further comprising a user input device, the user input device being configured to operatively couple to the control unit, wherein the user input device is configured to permit a user to modify at least one operational aspect of the fluid module.

6. The climate controlled bed of claim 5 , wherein the at least one operational aspect of the fluid module comprises a temperature or a temperature setting.

7. The climate controlled bed of claim 1 , further comprising at least one temperature sensor configured to measure a temperature of fluid entering the fluid module, the at least one temperature sensor is operatively coupled to the control unit.

8. The climate controlled bed of claim 7 , wherein the control unit is configured to regulate the fluid module based on both the humidity measured by the humidity sensor and the temperature measured by the at least one temperature sensor to reduce the likelihood of condensate formation by the fluid module.

9. A climate controlled bed comprising:
an upper portion having a top surface and a bottom surface, wherein the upper portion comprises at least one fluid distribution member;
a fluid module comprising a fluid transfer device and a thermal conditioning device that selectively heats or cools fluid entering the fluid module;
at least one fluid passageway placing the at least one fluid distribution member in fluid communication with the fluid module, wherein the at least one fluid passageway is routed at least partially through an interior of the upper portion;
at least one humidity sensor positioned along or near an inlet of the fluid module and configured to measure a humidity of fluid entering the fluid module; and
a control unit operatively coupled to the at least one humidity sensor and the fluid module, wherein the control unit is configured, based at least in part on the humidity measured by the humidity sensor, to reduce an amount of cooling provided by the thermal conditioning device to fluid passing adjacent said thermal conditioning device in order to reduce the likelihood of condensation formation by the fluid module.

10. The climate controlled bed of claim 9 , further comprising at least one temperature sensor configured to measure a temperature of fluid entering the fluid module, the at least one temperature sensor being operatively coupled to the control unit.

11. The climate controlled bed of claim 10 , wherein the control unit is configured to regulate the fluid module based on both the humidity measured by the humidity sensor and the temperature measured by the at least one temperature sensor to reduce the likelihood of condensate formation by the fluid module.

12. The climate controlled bed of claim 9 , wherein the thermal conditioning device comprises a thermoelectric device.

13. The climate controlled bed of claim 9 , wherein the at least one fluid distribution member comprises a spacer material.

14. The climate controlled bed of claim 9 , wherein the at least one fluid distribution member comprises a spacer fabric.

15. The climate controlled bed of claim 9 , wherein the at least one fluid distribution member is incorporated into a structure of the upper portion.

16. The climate controlled bed of claim 9 , wherein the upper portion comprises a mattress.

17. The climate controlled bed of claim 9 , further comprising a user input device, the user input device being configured to operatively couple to the control unit, wherein the user input device is configured to permit a user to modify at least one operational aspect of the fluid module.

18. The climate controlled bed of claim 17 , wherein the at least one operational aspect of the fluid module comprises a temperature or a temperature setting.
