Abstract
A bed system includes 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, or draw ambient air from the mattress, to achieve a desired temperature at the top of the mattress. 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.
Claims22
A mattress system comprising:
- a mattress having a mattress top surface that defines a first climate control zone and a second climate control zone;
- one or more air controllers in fluid communication with the first and second climate control zones and operable to cause air to flow through the first and second climate control zones individually;
- one or more processors;
- and
- a computer-readable storage medium coupled to the one or more processors having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- receiving a command to supply air to the first climate control zone that is heated;
- and
- in response to receiving the command, commanding the one or more air controllers to cause heated air to flow through the first climate control zone and to cause ambient air to flow through the second climate control zone, wherein adjusting a flow rate of ambient air through the second climate control zone reduces an amount of heat transferred from the first climate control zone to the second climate control zone.
5 more elements
A mattress system comprising:
- a mattress having a first climate control zone, a second climate control zone, a third climate control zone, and a fourth climate control zone;
- a first air chamber included in the mattress and configured to be inflated or deflated to adjust firmness at a first side of the mattress;
- a second air chamber included in the mattress and configured to be inflated or deflated to adjust firmness at a second side of the mattress;
- a first airflow pad included in the mattress and configured to allow air to flow through the first climate control zone;
- a second airflow pad included in the mattress and configured to allow air to flow through the second climate control zone;
- a third airflow pad included in the mattress and configured to allow air to flow through the third climate control zone;
- a fourth airflow pad included in the mattress and configured to allow air to flow through the fourth climate control zone;
- one or more air controllers in fluid communication with each of the first, second, third, and fourth climate control zones and configured to independently supply air to or draw air from each of the first, second, third, and fourth climate control zones;
- one or more processors;
- and
- a computer-readable storage medium coupled to the one or more processors having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- commanding the one or more air controllers to operate in a first mode whereby heated or cooled air is supplied to the first climate control zone while air is simultaneously drawn from the second climate control zone;
- commanding the one or more air controllers to operate in a second mode whereby heated or cooled air is supplied to the third climate control zone while air is simultaneously drawn from the fourth climate control zone;
- and
- commanding the one or more air controllers to adjust a flow rate of the air drawn from the second climate control zone or the fourth climate control zone to reduce an interference of the heated or cooled air supplied to the first climate control zone or the third climate control zone, the interference occurring from the first climate control zone to the second climate control zone and the third climate control zone to the fourth climate control zone.
12 more elements
A method for controlling multiple climate control zones of a mattress, comprising:
- receiving a command to supply first air to a first climate control zone;
- based on the command, controlling at least one air controller to supply first air to the first climate control zone to cause the first air to flow through the first climate control zone;
- and
- controlling the at least one air controller to supply second air to a second climate control zone to cause the second air to flow through the second climate control zone, wherein supplying the second air comprises adjusting a flow rate of the second air to the second climate control zone to reduce an interference of the first air on the second air, the interference occurring from the first climate control zone to the second climate control zone.
