Abstract
There is provided an air mat device comprising a mat unit that has an air cell; an air supply and exhaust unit that supplies air to the air cell and exhausts the air from the air cell; and a control unit that acquires a state change quantity of the air cell or a time required for a state change of the air cell, as a control reference value, and that controls the air supply and exhaust unit in accordance with the control reference value. There is also provided an internal pressure control method of an air cell according to the above configuration.
Claims16
An air mattress device comprising:
- an air cell;
- a pump unit configured to supply air to the air cell or exhaust air from the air cell;
- and
- a controller configured to set a first inner pressure to the air cell if a user's estimated weight is a first value, and the controller being configured to set a second inner pressure to the air cell if the user's estimated weight is a second value, the second value being different from the first value, the first inner pressure being different from the second inner pressure, and
- wherein the controller is configured to exhaust the air from a first state of the air cell to a second state of the air cell and then estimate the user's weight as the first value if a measured period of exhausting the air from the first state of the air cell to the second state of the air cell is a first period, the controller is configured to estimate the user's weight as the second value if the measured period of exhausting the air from the first state of the air cell to the second state of the air cell is a second period, the first value is larger than the second value, and the first period is longer than the second period.
