Description

Drain valve and door and window applying same

Technical Field

The utility model relates to the technical field of doors and windows, in particular to a drain valve and a door and window using the same.

Background

It is known that building doors and windows, one of the important components of a building, have a significant impact on the quality of the indoor environment. At present, in order to prevent water accumulation in the door and window frame, arranging a drainage mechanism on the door and window becomes one of the design specifications of the door and window, especially for the exterior enclosure door and window of a building. The existing door and window drainage mechanism generally has the main form that a drainage hole is arranged on a door and window frame body so as to communicate the space inside the door and window frame body or the space of a door and window rail groove with the outside by utilizing the drainage hole, thereby draining accumulated water in the door and window frame body or the door and window rail groove in time; however, when the drainage mechanism encounters strong convection weather, not only original accumulated water in the door and window cannot be smoothly drained outdoors, but also external rainwater flows backward easily under the driving of airflow, so that indoor water inflow or wall body water immersion is caused.

In view of this, various improved door and window drainage mechanisms are available in the market at present, for example, a door and window drainage hole cover with wind and insect prevention and various colors disclosed in the patent application No. 201721686959.7 chinese utility model is mainly to cover a housing cover plate of a prefabricated drainage hole by buckling the exterior of a door and window frame profile, and to provide a baffle plate capable of rotating relatively between the housing cover plate and the outer wall of the door and window frame profile, so as to adjust the extension path of the prefabricated drainage hole from the horizontal direction to the vertical downward direction. Although the drainage mechanism can avoid the problem that rainwater or mosquitoes directly invade the room due to the fact that the drainage hole is directly communicated with the outside to a certain extent, the drainage mechanism has the following defects: 1. the housing cover plate and the baffle plate are arranged to have negative influence on the overall structure and the external decoration effect of the door and window. 2. Under the influence of factors such as imperfect structural design of the baffle plate, under strong convection weather, external air flow still exists and can enter the shell cover plate from the lower part of the shell cover plate, and then the baffle plate is opened relative to the drain hole to invade into the drain hole or indoors.

Thus, there is still room for significant improvement in existing door and window drainage mechanisms.
