Description

[Detailed Description of the Invention] [Industrial field of application] This invention is installed on the ceiling and supplies the outside air to the room through the opening facing the room and the exhaust of the room air to the outside in parallel. The present invention relates to a simultaneous installation / exhaust type ceiling-mounted ventilation device.

[Prior Art] A ceiling-mounted ventilation system of simultaneous intake and exhaust type is equipped with an intake system for taking in outside air and an exhaust system for exhausting indoor air, and has an indoor air intake arranged on the ceiling surface. Ventilation of the room is performed by the outside air outlet. In this type of ventilation device, for example, as disclosed in Japanese Utility Model Laid-Open No. 56-90633, an exhaust flow and an intake flow of outside air are passed through a heat exchanger so that heat can be exchanged between them. However, due to the demand for compactness, the indoor air intake facing the room and the outdoor air outlet are often close to each other, and in the past, the indoor air intake and the outdoor air outlet were covered with a decorative panel. It has a lid. The decorative panel is provided with openings corresponding to the indoor air intake and the outside air outlet, respectively, and is configured such that the air is taken in and out from a direction separated by a grill or the like provided in the opening.

[Problems to be Solved by the Invention] In the above-described conventional ceiling-mounted ventilator, if the decorative panel is configured such that the decorative panel is flush with the ceiling surface, mixing between intake and exhaust can be prevented. If the decorative panel is shaped like a mountain in order to prevent mixing between intake and exhaust, the amount of protrusion into the room becomes large, and the interior quality deteriorates significantly.

The present invention has been made in order to solve such a conventional problem, and an object thereof is to obtain a ceiling-mounted ventilator which is not easily mixed between intake and exhaust, does not project from the ceiling surface, and is well-suited to the ceiling structure. And

[Means for Solving the Problems] A ceiling-mounted ventilator according to the present invention has an opening at the center which is divided into an indoor air intake and an outside air outlet, and blows outside air from the outside air outlet. A main body with built-in blowers for intake and exhaust, which exhausts indoor air from the indoor air intake and exhausts it, and is rotatable on the boundary side between the outside air outlet and the indoor air intake of this main body A pair of open / close panels pivotally supported to open and close the opening of the main body, driven with power supply to the blower to rotate the open / close panel in the pivot in conjunction with the operation and stop of the blower. And a panel drive device including a motor for opening and closing.

[Operation] In the present invention, the indoor air intake and the outside air outlet of the main body can be closed by a pair of open / close panels pivotally supported on the boundary side between the two when not operating, and two when operating. The pair of open / close panels can be opened by the panel drive device on the side separated from each other, and the open / close panels can be configured not to project from the ceiling, and mixing of intake and exhaust can be prevented.

[Embodiment] Both FIG. 1 and FIG. 2 show an embodiment of the present invention. The illustrated ceiling-mounted ventilation device is a heat exchange ventilation type having a heat exchange function, and has both an exhaust system configuration for exhausting indoor air and an intake system configuration for supplying outside air. The main body 1 arranged on the back of the ceiling has a lower surface that is parallel to the ceiling surface A, and has an outside air outlet 2 as an outlet structure for the air supply system and an indoor air intake 3 as an inlet structure for the exhaust system. And are formed. The outside air outlet 2 and the indoor air intake 3 are partitioned in the center, and the outside air outlet 2 is installed in the main body 1 from one ventilation passage of the heat exchanger 4 and is a blower 5 for intake air.
In addition, the indoor air intake 3 communicates with the exhaust blower 6 incorporated in the main body 1 to the other ventilation passage of the heat exchanger 4. A pair of opening / closing panels 7 hinged to each other at the center of the lower surface of the main body 1 so as to be rotatable with respect to each other is provided on the boundary between the outside air outlet 2 and the indoor air intake 3 at the hinge portion. Is pivoted to be located. Open / close panel 7
Has a flat area capable of covering the lower surface of the main body 1, and is rotated by a drive device between a horizontal closed position and an open position in which the hinge portion is bent like a chevron or a dogleg.
The drive unit corresponds to the power supply of the blowers 5 and 6, and the gear motor 8 to which the power is supplied, the gear motor 8 and the open / close panel 7.
And a linking member 10 including a link 9 for linking the open / close panel 7. The open / close panel 7 is opened / closed in conjunction with the operation / stop of the blowers 5 and 6. When the opening / closing panel 7 is opened, the opposite side of the hinge portion is opened as shown in FIG. 2, and the direction in which the indoor air intake 3 and the outside air outlet 2 are separated from each other is opened. Therefore, there is no mixing of intake air and exhaust air in which the blowout flow of the outside air is sucked into the intake flow of the indoor air. Further, the opening / closing panel 7 can be normally placed in a closed position where it is flush with the ceiling surface A, and can be fitted to the ceiling by having the same surface configuration as the ceiling material.

[Effects of the Invention] As is apparent from the description of the embodiments above, the ceiling-mounted ventilator of the present invention has an opening at the center, which is divided into an indoor air intake and an outside air outlet, A main body that incorporates blowers for intake to blow outside air from the outside air outlet and for exhaust to suck and exhaust indoor air from the indoor air inlet, both of the outside air outlet and the indoor air inlet of this main body It is pivotally supported on the border side so that it can rotate.
A set of two open / close panels that open and close the opening of the main body, and a motor that is driven together with power supply to the blower to rotate and open / close the open / close panel in the pivot part in conjunction with the operation and stop of the blower. Since it is provided with a panel drive device, the indoor air intake and the outside air outlet of the main body can be closed by a pair of opening and closing panels pivotally supported on the boundary side of both when not operating, During operation, a pair of open / close panels can be opened on the side separated by a panel drive, and the open / close panels can be configured to fit on the ceiling so as not to project from the ceiling, and mixing of intake and exhaust can be prevented. .
