Description

  The present invention relates to a rotating device for an electric rotating bed.

  A conventional electric rotating bed will be described with reference to an operation flow (FIG. 7). Conventionally, a bed controller using three types of switches such as a CW rotation switch 111, a CCW rotation switch 112, and an OFF switch 113 as shown in FIG. 5B is used, and the user presses the bed controller switch ( S101), the electric rotating bed was rotated. When the motor rotates for a predetermined time (S102 to S104), the motor is stopped (S105). After the user leaves, it is necessary to rotate the rotating bed to a predetermined position when making a bed (S106 to S110). ).

Problems to be solved by the present invention

  The bed make-up is usually placed at a fixed position on the head side and the leg side (for example, a pillow placed on the head side is placed at a position where it is easy to see the TV (FIG. 1 (a)).

  However, since the rotation of the electric rotating bed is controlled by time, it does not stop at a predetermined position (FIG. 1 (a)) after the CW rotating switch 111 or the CCW rotating switch 112 is pressed and the electric rotating bed rotates for a predetermined time. Therefore, after the user exits using the electric rotating bed (FIG. 1 (b)), the electric rotating bed is not in a predetermined position, and it is necessary to rotate the electric rotating bed to a predetermined position when making a bed, Since it is necessary to monitor for a long time until it rotates to a predetermined position, there has been a problem that bed making becomes inefficient.

  In addition, after the user presses the switch on the bed controller of the electric rotating bed and stops at an arbitrary position after rotating for a certain time (FIG. 1B), when the user tries to watch the TV, the user can easily watch the TV. There was also a problem that the position of the pillow had to be moved because it was not in position.

  In view of such circumstances, an object of the present invention is to provide an electric rotating bed that stops at a predetermined position.

Means for solving the problem

  In order to solve the above-mentioned problem, the rotating device of the electric rotating bed according to claim 1 is a motor of a driving source, a bed that rotates in conjunction with the rotation of the motor, and when the bed is in a specific position. There is a position sensor that outputs a signal, an operation switch that operates the rotation direction of the motor, and a control circuit that controls the motor to rotate for a certain period of time when the operation switch is pressed. Then, stop control of the motor is performed based on a signal from the position sensor, and the rotating bed is stopped at a predetermined position.

  The rotating device of the electric rotating bed according to claim 2, a motor of a driving source, a bed that rotates in conjunction with the rotation of the motor, a position sensor that outputs a signal when the bed is at a specific position, There is a reset operation switch that rotates the bed to a predetermined position and a control circuit that controls the motor. When the reset operation switch is pressed, the motor is controlled to stop based on a signal from the position sensor and rotates. The bed is stopped at a predetermined position.

Effect of the invention

  According to the present invention, since the electric rotating bed stops at a predetermined position, the user stops at a position where the user can easily see the TV. In addition, even with bed make-up, the electric rotating bed automatically rotates to a predetermined position, so that bed make-up is easy and time required for bed make-up can be reduced.
