[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a suction port device which is disposed on a ceiling or the like in a space to be air-conditioned and suctions air in the space, and particularly relates to a suction port device provided with an air purification filter in the device.

[0002]

[Prior art]

 Conventionally, various filters are installed inside the suction port device that is installed on the ceiling or wall of the indoor space subject to air conditioning as part of the air conditioning equipment, and that sucks indoor air for the purpose of ventilation etc. In some cases, the sucked indoor air can be passed through this filter to remove dust and odor sources in the air. FIG. 4 shows an example of such a conventional suction port device with a filter. FIG. 4 is a schematic diagram illustrating the configuration of a conventional suction port device.

In FIG. 4, a conventional suction port device 100 has a rectangular or square opening area, and is formed with a frame portion 101 a surrounding the opening area, and is attached to a ceiling (or wall) 50. And an opening frame 101 that is connected to a duct 51 inside the ceiling (or wall) 50 and receives a negative pressure from the duct 51 to suck indoor air into an opening area. A frame portion 102a that fits inside the frame portion 101a is formed and has a rectangular or square opening area in the center, and the end portion of the frame portion 102a is rotatable on the inner side wall of the opening frame body 101. A middle frame 102 pivotally mounted on the opening frame body 101 to be openably and closably attached thereto, and a plurality of wing cross-sectional shapes arranged in parallel near the room in the opening area of the middle frame 102 to rectify the sucked air. A rectifying blade 103 and a filter 104 that is detachably disposed adjacent to the downstream side of the rectifying blade 103 in the opening region of the middle frame 102 and that allows the sucked indoor air to pass therethrough to remove dust and the like. It is.

In the conventional suction port device 100 based on the above configuration, the indoor air is sucked substantially vertically into the opening region of the middle frame 102 while being guided by the rectifying vanes 103 fixed vertically, and the filter 104 Then, the dust passes through the inner space of the opening frame 101, reaches the duct 51, and goes to the downstream air conditioner (not shown).

When the filter 104 is to be cleaned or replaced by the conventional suction port device 100, the opening / closing fitting 102 b for fixing the inner frame 102 and the opening frame 101 is loosened to release the fixing, and the inner frame 102 is opened. After taking out the body 101 by rotating it indoors, the filter 104 attached to the middle frame 102 is removed.

[0006]

[Problems to be solved by the invention]

 Since the conventional suction port device is configured as described above, it has a double frame of the opening frame body 101 and the middle frame 102, and the frame portion on the indoor side also has a double width so that the width looks thick. In addition, there was a problem in appearance, such as inconsistency in design because the outlet devices used in pairs were generally single frames. In addition to the fact that the structure of the connecting portion between the opening frame 101 and the middle frame 102 is complicated and time-consuming to manufacture, the effective opening area is reduced by the double frame, and the resistance is large and There was a problem that the cost would be high, for example, the air conditioner had to be able to handle high loads.

In addition, while the middle frame 102 is rotated to open and close the opening frame 101 to replace and clean the filter 104, if the width of the opening frame 101 is small, the rotation of each part of the middle frame 102 is performed. There is a problem that the difference in radius becomes relatively large and a portion that interferes with the inner surface of the opening frame body 101 is generated and the middle frame 102 cannot be taken out, so that a narrow suction port having a small short side dimension cannot be realized. did. Further, a sufficient gap is required between the opening frame body 101 and the middle frame 102 in order to secure the turning radius of the middle frame 102 so that it can be opened and closed. As a result, there is a problem that the air purification performance is reduced.

On the other hand, a suction port device having a single frame structure without a middle frame, in which a filter is directly supported by an opening frame body in consideration of the appearance, has conventionally existed, and a large effective opening area has been secured. Although the resistance was reduced, the opening frame had to be removed from the ceiling or the wall due to the integral structure when removing the filter, and this required a lot of work.

The present invention has been made to solve the above-mentioned problems, and has excellent appearance, high efficiency, easy attachment / detachment of a filter to improve workability, and simplification of the structure and cost reduction. An object of the present invention is to provide a suction port device that can be downed.
