Bed air control system

#This document relates to bed systems, and more particularly to devices, systems, and methods for controlling air flow and temperature of a bed.

#In general, a bed is a piece of furniture used as a location to sleep or relax. Many modern beds include a soft mattress on a bed frame. The mattress may include springs, foam material, and/or an air chamber to support the weight of one or more occupants. Various features and systems have been used in conjunction with beds, including heating and cooling systems for heating and cooling a user of a bed.

#Some embodiments described herein include a bed system with microclimate control capabilities for providing quality sleep experience. The bed system can include a microclimate control subsystem configured to supply conditioned air (e.g., heated or cooled air) to a mattress to achieve a desired temperature at the top of the mattress. In some implementations, conditioned air can be supplied to one or more airflow pads arranged under the mattress top, so that the conditioned air is distributed to the mattress top through the airflow pads. Alternatively, the microclimate control subsystem can draw ambient air from the mattress, thereby conditioning the temperature at the top of the mattress. For example, air is forced to be drawn from the airflow pads so that air at the mattress top is suctioned into the mattress and permits for the air to be circulated and refreshed at the mattress top. Utilizing supply of conditioned air to provide air at desired temperature to the mattress system, or utilizing air suction to drain heat away from the mattress system, can provide precise microclimate control at the mattress, thereby permitting conformable sleep.

#FIG. 1 illustrates an example bed system 100 for providing a quality sleep experience with an example local bed system 101. The local bed system 101 can include a bed 102 and a bed control system 110 used in conjunction with the bed 102 and configured to control one or more user comfort features of the bed 102.

#The bed 102 can include a mattress 104 and a foundation 106. In some embodiments, the mattress 104 can be an air mattress having an inflatable air chamber and a controller for controlling inflation of the inflatable air chamber. In other embodiments, the mattress 104 does not include an air chamber. For example, the mattress 104 may include foam and/or springs instead of or in addition to an inflatable air chamber. The mattress 104 can be sized and shaped as a twin mattress, full mattress, queen mattress, king mattress, California king mattress, split king mattresses, partially split mattress (e.g. a mattress that is split at the head and/or foot ends and joined in the middle), and/or other mattress as suitable for the application. The foundation 106 is positioned under the mattress 104 to support the mattress 104. In some embodiments, the foundation 106 can be an adjustable foundation with one or more articulable sections, such as for raising the head and foot of the foundation 106 and the mattress 104. In other embodiments, the foundation 106 can be a stationary foundation.

#The bed 102 can be configured to provide a microclimate control of the mattress 104. In some implementations, the bed 102 provides a foot warming function. For example, the bed 102 can include a foot warming device 120 which is disposed on the mattress 104 or incorporated in the mattress 104 and at a foot side of the bed 102. The foot warming device 120 can be disposed on a top of the mattress 104, included in the mattress 104, or disposed at other locations of the bed 102 and/or in other configurations. The foot warming device 120 can include an electronic heating element in some implementations. The foot warming device 120 can include an air circulation element through which heating air is circulated in other implementations. Other configurations are also possible.
