Abstract

A ventilating device includes a frame forming an outer contour, an airflow path formed by a flowing of air inside the frame, and a plurality of orifices configured to measure a static pressure in a chamber where the airflow path is located, wherein at least one orifice of the plurality of orifices is further configured to drain water out of the frame. In the present disclosure, the orifice for static pressure measurement is provided in the air supply path and/or the air discharge path at a position where the dew is dominantly accumulated, the drainage function and the function of measuring the static pressure may be realized simultaneously, reducing the cost and ensuring air tightness.

First claim

What is claimed is:

1 . A ventilating device, comprising:
a frame forming an outer contour, an airflow path formed by a flowing of air inside the frame, and a plurality of orifices configured to measure a static pressure in a chamber where the airflow path is located, wherein at least one orifice of the plurality of orifices is further configured to drain water out of the frame.

2 . The ventilating device according to claim 1 , wherein,
the airflow path comprises an air supply path for allowing the air to flow from outside to a room, and an air discharge path for allowing the air to flow from the room to outside; a heat exchanging element for exchanging energy between indoor air and outdoor air is provided at an intersection position between the air supply path and the air discharge path; and the plurality of orifices are provided in the airflow path at a position where the air hasn't reached the heat exchanging element yet or in the airflow path at a position where the air has already left the heat exchanging element.

3 . The ventilating device according to claim 1 , wherein a surface of the frame is provided with a panel capable of being opened and closed, and the plurality of orifices are provided on the panel.

4 . The ventilating device according to claim 1 , wherein a fixing bolt for fixing a measuring tube of different sizes of a static pressure gauge is provided in each of the plurality of the orifices.

5 . The ventilating device according to claim 4 , wherein,
the fixing bolt comprises a fixing bolt body of a hollow truncated cone shape, the fixing bolt body comprising: a first bottom surface extending into the frame and provided with a first opening, and a second bottom surface positioned outside of the frame and provided with a second opening.

6 . The ventilating device according to claim 5 , wherein,
the fixing bolt further comprises an outer flange provided in an insertion direction of the measuring tube and having a larger diameter than that each of the plurality of orifice, a stopper extending outwardly in a rotational direction of the fixing bolt is provided on a surface of the outer flange facing the fixing bolt body, and the outer flange is formed with a third opening communicating with the second opening; one end of the stopper is provided with a hook portion and the other end thereof is provided with a connecting portion connected to the outer flange; and each of the plurality of the orifices comprises a main orifice portion through which the fixing bolt body passes, and a lateral orifice portion through which the stopper passes.

7 . The ventilating device according to claim 6 , wherein, an observation hole corresponding to the stopper is provided on the outer flange; and
a recess or a projection is provided on the outer flange.

8 . The ventilating device according to claim 6 , further comprising a cover, wherein
the cover comprises a covering portion covering the third opening, and an engaging portion adapted to be engaged into the second opening; wherein the engaging portion is provided with a notch for enabling deformation of the engaging portion, and a gap is formed between the covering portion and the third opening.

9 . The ventilating device according to claim 3 , wherein,
an inner wall of the panel is provided with a thermal insulating member preventing heat exchange between the air inside the ventilating device and the air outside the ventilating device, and the thermal insulating member is provided with a guide hole penetrating through the thermal insulating member.

10 . The ventilating device according to claim 9 , wherein,
a water storage portion recessed towards the panel is formed on the thermal insulating member, and the guide hole is provided at a lowest point of the water storage portion.

11 . The ventilating device according to claim 1 , wherein,
the ventilating device is an air blower or a heat exchanger.

12 . The ventilating device according to claim 1 , wherein
when the ventilating device is mounted on a wall other than a ceiling, the plurality of orifices are provided on a surface acted as a bottom surface of the frame.
