Description

[Detailed explanation of the invention] Industrial field of use In recent years, ceiling-embedded ventilation fans that simultaneously supply and exhaust air have become popular as houses become more airtight. The present invention relates to such a simultaneous supply/exhaust type ceiling-embedded ventilation fan.

Conventional configuration and its problems Figure 1 shows a conventional simultaneous supply/exhaust type ceiling-embedded ventilation fan.
FIG. 2 will be explained. If the ceiling plate 101 is thin as shown in FIG.
are separated, but as shown in Figure 2, the ceiling plate 10
1 is thick or the louver is shifted laterally, the separation plate B107 of the main body 106 and the louver 102
Since a gap is created between the louver and the separation plate A103, and the air supply passage 104 and the exhaust passage 105 are short-circuited inside the louver, there is a drawback that the air supply and exhaust air are mixed and effective ventilation cannot be performed.

Purpose of the invention This invention solves these conventional drawbacks, and allows effective ventilation without short-circuiting between the air supply and exhaust passages even when the ceiling panel is thick or the louvers are installed out of alignment. The purpose is to

Structure of the invention The present invention is designed to separate the air supply passage and exhaust passage provided in the main body by providing a plurality of separation plates approximately in the center inside the louver to prevent short-circuiting between the louver and the main body even if the ceiling panel becomes thick. The plate is configured to freely bend and come into contact with a plate separating the air supply passage and exhaust passage of the main body between a certain distance between the main body and the louver.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

The inside of the box-shaped main body 1 having an opening 8 on the lower surface,
A heat insulating space is formed by a pair of partition plates A2 and B3 vertically disposed facing each other approximately in the center, and is partitioned into an air supply passage 4 and an exhaust passage 5. Air blowers 6 are provided in both the air supply passage 4 and the exhaust passage 5. Partition plate A
2 and the partition plate B3 are horizontally connected by a partition connecting plate 7 at the tip of the lower surface of the main body 1 on the opening 8 side. In addition, a louver 9 is provided in the opening 8 on the lower surface of the main body 1.
is attached with the tips of its four circumferences in contact with the ceiling plate 13. A separation plate 10 made of a soft vinyl chloride sheet is erected approximately at the center of the inside of the louver 9 so as to come into contact with the partition connecting plate 7 . Further, the louver 9 has an indoor discharge port 11 of the air supply passage 4 and an indoor suction port 12 of the exhaust passage 5.

Effects of the invention The simultaneous air supply and exhaust type ceiling-embedded ventilation fan having the above configuration is arranged on a thick ceiling panel 13 as shown in FIG. The separation plate 10 that has been designed has its tip bent freely along the partition connecting plate 7 until the distance between the main body 1 and the louver 9 reaches a predetermined distance, and the distal end of the separating plate 10 always comes into contact with the partition connecting plate 7. The supply air and exhaust air will not mix.
