inflatable bed having a unit incorporated electric air pump for inflating a mattress assembly

摘要

An inflatable bed comprising: a mattress assembly (1) having at least one air chamber (E); and a unit of electric air pump (2) in connection with said mounting mattress (1) and including: a first pump device (21) in fluid communication with said air chamber (E) in said assembly mattress ( 1) to inflate said air chamber (E). a first control valve (25) operable to allow and interrupt the fluid communication between ambient air and said air chamber (E), said first control valve (25) being disposed between the ambient air and said air chamber (E ), a second pump device (22) in fluid communication with said air chamber (E) separated fluidly from said first control valve (25) for inflating said air chamber (E), a pressure sensor (27) fluid communication with said air chamber (E), and a controller (5); said controller (5) being configured to control said first control valve (25) to allow fluid flow air amiente in said air chamber (E) therethrough such that said first pump device (21) performs initial inflation of said air chamber (E) to a first pressure value; said pressure sensor (27) configured to detect when it has reached the first pressure value; and said controller (5) being configured such that when said pressure sensor (27) detects that it has reached the first pressure value, said controller (5) controls said first control valve (25) to interrupt the flow of fluid ambient air in said air chamber (E) and deactivates said first pump device (21), wherein said second pump device (22) is operable to perform the subsequent inflation of said air chamber to a second value Pressure.
