Mattress and method of adjusting pressure of mattress

摘要

A mattress and a method of adjusting the pressure of a mattress are provided. The method includes a first process of measuring internal pressure before a user lies on a mattress having at least two zones in which cells having a closed inner space filled with fluid are formed, a second process of measuring an increase in the internal pressure of each cell occurring when the user lies on the mattress, and an average pressure adjusting process of adjusting an amount of the fluid introduced into each cell of the mattress based on a pressure variation caused by a difference between the internal pressure detected from each cell in the first process and the internal pressure detected from each cell in the second process.

1. A method of adjusting air pressure of a mattress, the method comprising:
providing a mattress comprising:
a mattress body comprising a plurality of air compartments, which comprises a first air compartment and a second air compartment,at least one air pressure sensor configured to detect air pressure within the first and second air compartments, andan air pump configured to supply air pressure to the plurality of air compartments; obtaining an unloaded air pressure for each of the plurality of air compartments,using the at least one sensor, when no load is placed on the mattress, the first air compartment having a first unloaded air pressure. the second air compartment having a second unloaded air pressure; obtaining a loaded air pressure for each of the plurality of air compartments, using the at least one sensor, when a user is on the mattress,, the first air compartment having a first loaded air pressure, the second air compartment having a second loaded air pressure; obtaining an average air pressure difference between the unloaded air pressures and the loaded air pressures of the plurality of air compartments; determining a first characteristic value for the first air compartment based on the first loaded air pressure, the first unloaded air pressure, and the average air pressure difference such that the first characteristic value represents a differential between the average air pressure difference and a first air pressure difference, wherein the first air pressure difference is a difference between the first loaded air3 pressure and the first unloaded air pressure; setting a first target air pressure or a first air pressure adjustment for the first air compartment based on the first characteristic value; determining a second characteristic value for the second air compartment based on the second loaded air pressure, the second unloaded air pressure, and the average air pressure difference such that the second characteristic value represents a differential between the average air pressure difference and a second air pressure difference, wherein the second air pressure difference is a difference between the second loaded air pressure and the second unloaded air pressure; setting a second target air pressure or a second air pressure adjustment for the second air compartment based on the second characteristic value; adjusting air pressure, using the pump, of the first air compartment based on the first target air pressure or the first air pressure adjustment; and adjusting, air pressure using the pump, of the second air compartment based on the second target air pressure or the second air pressure adjustment.
