Abstract
The utility model is a fresh air inlet exchange device containing wall through pipe and rainproof device and airflow regulating device installed separately on the outer end and the inner end, a small blower is installed in the axial center in the wall through pipe. The advantages of the utility model is provided with the two functions to ventilate by natural wind and forcedly by wind machine, no wind machine needs to open while the air pressure in the outer and inner of the room is quite larger, natural ventilation is adopted by the gap between the blower and the inner wall of the wall through pipe. While the ventilation flow can not meet the requirements and then to open the blower to improve ventilation airflow by ventilating forcedly, combining with the airflow regulating device to regulate the ventilation airflow in an appropriate range to meet the requirements to fresh air under various conditions. It can supply fresh air into room and drain such gas as contaminated air or fume and etc. out of the room.
Description
Technical field
The utility model relates to a kind of difunctional fresh air switch of registering one's residence, and is mainly used in the ventilation of indoor and outdoor.
Background technology
Existing a kind of ventilation unit is realized circulating naturally of indoor-outdoor air by wall pipe, at the outdoor end and the indoor end of wall pipe rain insensitive device and volume adjusting apparatus is housed respectively.Its shortcoming is the circulation naturally that only relies on air, and under the identical or very approaching situation of the air pressure of indoor and outdoor, the circulation of air is less, can not satisfy the demands.
Summary of the invention
The purpose of this utility model just provides a kind of difunctional fresh air switch of registering one's residence, to solve the circulation naturally that only relies on air that prior art exists, under the identical or very approaching situation of the air pressure of indoor and outdoor, the circulation of air is less, the problem that can not satisfy the demands.
The technical solution of the utility model is: comprise wall pipe and be installed in the rain insensitive device and the volume adjusting apparatus of its outdoor end and indoor end respectively, a small-sized fan is installed in the axle center in described wall pipe.
Described rain insensitive device can adopt blinds, umbrella hat or elbow; Described volume adjusting apparatus can adopt and open and close lid, rotary switch or sliding door.
In described wall pipe, be provided with air filtration layer net.
Between the outdoor end of described wall pipe and rain insensitive device, be equipped with and be connected transverse tube or standpipe.
The utility model has the advantages that to have gravity-flow ventilation and utilize the force ventilated two kinds of functions of blower fan, can when indoor and outdoor air pressure is big, not need to open blower fan, utilize the gap gravity-flow ventilation between blower fan and the wall pipe inwall; And when ventilation can not be satisfied the demand, open the blower fan forced ventilation, and improve ventilation, combine with the ventilation adjusting device again, ventilation is adjusted in the OK range, satisfied under the various situations demand to fresh air.
