Application No. 10-2008-0118919 filed by the present applicant discloses the configuration of the closing control means for automatically enabling the closing of the drawer.

Such a conventional closing adjustment means is used not only for closing the drawer, but also for closing the door and automatically opening the drawer or the door.

In the structure of the conventional closing control means (opening and closing control device), a damper and a tension spring are connected to one switch. Therefore, when the door or drawer is closed or opened, the opening and closing speed is decelerated by the damper, and finally the door or drawer is completely opened and closed by the force of the tension spring.

However, in such a conventional structure, a problem arises in that the door or drawer is not completely closed. That is, in the conventional structure, since the stroke of the switch, the stroke of the damper, and the stroke of the tension spring are the same size, it requires more force than the tension of the tension spring when opening or closing the door or drawer, causing inconvenience to the user. Done.

In addition, in order to solve this problem, if the stroke of the switch or damper is reduced, the damping force (absorbing force) of the damper that absorbs the kinetic energy of the door or drawer is reduced. That is, if the damper force is constant, the energy absorption of the damper is proportional to the operation of the damper. Therefore, since the operation stroke of the damper is reduced, the amount of energy absorption is also reduced, so that it is impossible to reduce the stroke of the switch and the damper.
