AI Technical Summary

Technical Problem

The thermal insulation performance of existing motorized casement window frames deteriorates after the installation of motors and other drive components, necessitating improvements in the thermal insulation performance of motorized casement windows.

Method used

An upper and lower thermal insulation strip is installed in the window frame profile to form a thermal insulation space. An opening is made in the upper thermal insulation strip to install driving components such as motors in the thermal insulation space. The first sealing strip is used to block airflow from entering the room. The second and third sealing strips are combined to form a multi-seal structure. Insulation material is filled into the thermal insulation space.

Benefits of technology

While controlling the thickness of the window frame, the thermal insulation and sealing performance of the electric casement window were improved, achieving a balance between the utilization of the motor installation space and the thermal insulation performance.

Abstract

This utility model relates to the field of door and window technology, and discloses a window frame profile and a casement window. The window frame profile includes: a frame strip with an upper thermal insulation strip and a lower thermal insulation strip spaced apart along the vertical direction in the middle, forming a thermal insulation space between the upper thermal insulation strip and the lower thermal insulation strip, and the upper thermal insulation strip having an opening communicating with the thermal insulation space; and a first sealing strip connected to the top side of the upper thermal insulation strip, the first sealing strip being closer to the front side of the frame strip relative to the opening. This utility model utilizes the position of the frame strip within the thermal insulation space to install driving components such as motors, thereby controlling the thickness of the frame strip while also taking into account the thermal insulation performance of the frame strip, thus improving the practicality of the electric casement window.
