Meanwhile, when the left and right turning keys 286 are input, the processor 210 displays the set tilt angle and time respectively (S360), and the designated time corresponding to the input of the tilt angle key 285 and the tilt time key 284 and set the angle (S370).

If the tilt angle key 285 and the tilt time key 284 are not input, the processor 210 sets left and right turning (basic turning) according to the default value (S380).

The air pump 270 is operated and the valve 260 is controlled to supply air to the air mat 100 to perform a turning operation (S410).

The processor 210 can perform left and right turning for each line, for example, by alternately controlling the first line (L1) and the second line (L2), and also the 11th line (L11) and the 12th line (L12). Left and right turning can be performed by controlling the 13th line (L13) and the 14th line (L14).

The processor 210 checks the current operating state and displays the operating state for normal, emergency, and cyclic stop in the status window 294 (S420).

The processor 210 performs the turning operation in cycles until the mode is released (S430), and when one cycle is completed, the turning operation is repeated again according to the designated cycle.

In the case of automatic mode, the processor 210 repeats the operation until the mode is released, and in the case of manual setting, the processor 210 terminates the operation after performing the operation of one cycle or a designated cycle.

The processor 210 stops operating when the mode is released or the power key 289a is input (S440).

Therefore, the present invention distributes the pressure on the user's body through alternating levitation, allows the user to change the posture as needed, and performs turning movements to the left and right, as well as turning the head, left, right, and legs through dynamic turning mode. By automatically performing the turning motion for each body part in order and automatically repeating the turning motion even if the user does not set it individually, bedsores are prevented, the massage effect is improved, and the user's convenience is improved.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely illustrative, and those skilled in the art will recognize that various modifications and other equivalent embodiments can be made therefrom. You will understand. Therefore, the true technical protection scope of the present invention should be determined by the scope of the patent claims below.
