Background

At present, a casement window is a window with one side of a window sash hinged with a window frame by a hinge, has the characteristics of large opening angle and large ventilation volume, and is widely applied to various buildings. The traditional casement window is opened and closed by manually pushing and pulling, and the problems of inconvenient operation, large potential safety hazard, incapability of reliably locking and the like exist. Therefore, those skilled in the art have developed various electric window openers to open and close the casement window; the common electric window opener mainly comprises a push arm or a push arm assembly hinged between a window sash and a window frame, and the push arm is driven by a motor to swing or move so as to open and close the window sash. Various multi-point locks are designed to lock the closed casement window sash; the common multi-point lock mainly comprises a plurality of locking points and a pull plate for linking the locking points, wherein a locking nail is arranged on the pull plate, and the locking nail is shifted by utilizing a motor to drive a shifting fork, so that the multi-point lock can be electrically locked or unlocked.

When the window openers and the multipoint locks are used for opening windows, the multipoint locks need to be opened firstly, and then the window openers are used for opening windows; when the window is closed, the window opener is required to be used for closing the window, and then the multipoint lock is locked. The existing casement window is not provided with a corresponding mechanical structure to link the window opener and the multipoint lock in sequence, so that the window opener and the multipoint lock can only be respectively provided with motor drives, and sequential actions of the window opener and the multipoint lock are realized through a sequential module in a control program. Therefore, the arrangement of the two motors and the control module is not only unfavorable for the control of production and use cost, but also causes the complexity of the whole circuit structure of the window opener and the multipoint lock, the increase of fault points and the unfavorable guarantee of service life.
