Description

Window type ventilation device for building

Technical Field

The patent of the utility model relates to a natural ventilator for building, especially a window formula ventilation unit for building.

Background

In the existing window type ventilation products, the sound insulation performance is difficult. The utility model discloses this problem can be solved.

SUMMERY OF THE UTILITY MODEL

The utility model provides a window formula ventilation unit for building for solve above-mentioned prior art's problem.

The utility model provides a window formula ventilation unit for building sees from the crosscut section, is equipped with three air chamber along by indoor to outdoor circulation of air direction in proper order: the indoor cavity and the middle cavity are communicated with each other through a gate gap; the middle cavity and the outdoor cavity are communicated with each other through a middle seam, and the opening seam is provided with an openable air brake. One side of the window type ventilation device faces indoors, and the other side faces outdoors. The two ends of the window type ventilation device are provided with end covers, one side of each end cover facing the indoor is provided with an air brake switch, the angle of the air brake can be adjusted through the air brake switch, so that the opening of a brake gap can be adjusted, the brake gap can be fully opened, fully closed or only partially opened, and the indoor ventilation volume can be adjusted through adjusting the opening of the brake gap.

When the window type ventilation device is installed, one side faces outdoors; the opening of the air cavity facing the outdoor side faces downwards, and an anti-mosquito net is arranged at the opening. The inner wall of the window type ventilation device can be attached with sound absorption materials according to the requirement.

Detailed Description

Ventilation and sound insulation are a pair of contradictions. The window type ventilation device is limited to the requirements of installation position and beauty, and the external dimension cannot be very large, so the requirement difficulty of sound insulation technology is high. The window type ventilation device is different from other modes in sound insulation treatment, and generally, noise reduction modes generally comprise absorption, shielding, refraction and reflection.

The ventilation volume of the window type ventilation device can be selected according to the requirement, the longer the length is, the larger the ventilation section of the ventilation narrow slit is, and the larger the ventilation volume is; the ventilation quantity can be adjusted by adjusting the opening of the air brake.

The window type ventilation device is small in overall dimension, the installation position is a window or a door, the window type ventilation device can be integrated with a door and a window, the installation is convenient, the operation is easy, and the wall body is not required to be damaged, so that the whole effect is safe, simple, convenient and tidy.

The description and applications of this patent are illustrative and explanatory only and are not intended to limit the scope of this patent to the embodiments described above. Variations and modifications of the embodiments disclosed herein are fully possible, and alternative and equivalent various components of the embodiments are well known to those skilled in the art. It will also be apparent to those skilled in the art that the present patent can be embodied in other forms, structures, arrangements, proportions, and with other components, materials, and parts, and other changes and modifications, without departing from the spirit or essential characteristics thereof, and without departing from the scope and spirit of the present patent.
