Abstract
A bed includes a mattress set on which a user's body is placed, an adjustable bedframe to adjust a position or orientation of the mattress set for various sitting and sleeping positions, and a dryer to dry the mattress set. The dryer includes a fan, a filter, and a heater to discharge filtered hot air toward the dryer to reduce mildew and mites. A humidity sensing sheet may be provided to sense a humidity level at different regions or areas of the bed, and the dryer may be controlled to supply hot air to regions of the bed having a higher humidity level than a predetermined humidity level or humidity range.
Claims19
A method of controlling mattress humidity, comprising:
- sensing a humidity at a plurality of points on a mattress;
- determining respective average humidity values for a plurality of regions of the mattress based on the sensed humidity at the plurality of points;
- and
- performing a drying operation based on the determined average humidity values,
- wherein sensing the humidity at the plurality of points on the mattress includes:
- repeatedly sensing the humidity;
- determining a difference between a current sensed humidity and a previously sensed humidity;
- comparing the determined difference to a predetermined error range;
- when the determined difference is within the predetermined error range for a first predetermined time period, proceeding to the determining of the respective average humidity values for the plurality of regions of the mattress;
- and
- when the determined difference the predetermined error range for a second predetermined time period, stopping sensing for a third predetermined time period and repeating the repeatedly sensing of the humidity after the third predetermined tithe period, and
- wherein performing the drying operation includes:
- comparing the respective average humidity values for the plurality of regions to a predetermined humidity range;
- and
- operating at least one fan provided below the mattress to suction air and selectively discharge air toward at least one of the regions of the mattress having ones of the respective average humidity values that exceed the predetermined humidity range to dry the at least one of the regions of the mattress.
A method of controlling a mattress humidity, comprising:
- performing a humidity scan of the mattress;
- storing data from the humidity scan;
- determining, using the stored data, average humidity values corresponding a plurality of regions of the mattress;
- generating, via the processed data, a humidity image reflecting the humidity values at the plurality of regions;
- outputting the humidity image on a display;
- comparing the determined average humidity values to predetermined humidity values;
- and
- performing a drying operation to dry the mattress based on the the comparing of the determined average humidity values to the predetermined humidity values,
- wherein performing humidity scan includes:
- repeatedly sensing the humidity;
- determining a difference between a current sensed humidity and a previous sensed humidity;
- comparing the determined difference to a predetermined error range;
- when the determined difference is within the predetermined error range for a first predetermined time period, proceeding to the step of determining the average humidity values;
- and
- when the determined difference is not within the predetermined error range for a second predetermined time period, stopping sensing for a third predetermined time period, and repeating the step of repeatedly sensing;
- the humidity after the third predetermined time period, and
- wherein performing the drying operation includes selectively discharging air toward at least one of the regions of the mattress having ones of the respective average humidity values that exceed the predetermined humidity values to dry the at least one of the regions of the mattress.
