The ventilation device according to the present invention is a ventilation device including a box-shaped main body, a louver provided below the main body, an air supply blower provided in the main body, and an exhaust blower. Includes an air supply panel, a ring panel, a panel holding portion, a louver frame and an inspection panel, the air supply panel and the ring panel are held by the panel holding portion on the louver frame, and the louver frame is an inspection opening. The inspection panel is provided in the inspection opening, the louver has an air supply port on the air supply panel side, a ring air port on the ring air panel side, and an outside air port and an outside air port on the side surface of the main body. An exhaust port is provided, an air supply air passage for blowing outdoor air from the outside air port to the air supply port is formed by the air supply blower, and indoor air is formed from the ring air port to the exhaust port by the exhaust blower. An exhaust air passage is formed, the panel holding portion includes a side surface portion, a bottom surface portion, a hook portion and a holding portion, the side surface portion is connected to the louver frame, and the bottom surface portion is the said. Connected to the side surface portion, the hook portion is provided so as to project upward from the bottom surface portion, and the holding portion is provided so as to project from the side surface portion toward the hook portion, and the air supply panel is provided. Includes a front portion, a bent portion and a folded portion, and when the air supply panel is closed, the front portion forms a part of the air supply air passage with the louver frame, and the bent portion is formed. The front portion and the folded portion are connected, and the folded portion is provided so as to be folded in a direction overlapping the front portion, and has a holding portion and a hook hole into which the hook portion is inserted. When the air supply panel is open, the holding portion of the air supply panel is inserted into the hook hole, and when the air supply panel is closed, the air supply panel is hooked. This is a ventilation device in which the portion is inserted into the hook hole.

As a result, when the air supply panel is open, the air supply panel is held by the panel holding portion by inserting the holding portion into the hook hole, and when the air supply panel is closed, the air supply panel is held. The hook is held by the panel holding portion by being inserted into the hook hole. This makes it easy to remove the panel and improves workability.

Further, the folded-back portion includes a folded-back surface provided with the hook hole, and when the air supply panel is open, the air supply panel is supported by the bottom surface portion by the end portion of the folded-back surface, and the air supply panel is supported by the bottom surface portion. When the air supply panel is closed, the air supply panel may be supported by the bottom surface portion by the folded surface and the bottom surface portion in close contact with each other.

With such a configuration, when the air supply panel is open, such as when the air supply panel is attached, the air supply panel is held by the panel holding portion by contacting the end portion of the folded surface with the bottom surface portion. When the air supply panel is closed, such as when supplying air, the air supply panel is supported by the bottom surface portion by the folded surface and the bottom surface portion in close contact with each other. As a result, the panel can be easily removed and workability is further improved.

Further, the air supply panel is rotated around the end of the folded surface as a fulcrum so that the holding portion is inserted into the hooking hole and the hooking portion is inserted into the hooking hole. It may be configured to switch between the state and the state.

As a result, when opening and closing the air supply panel, the work can be performed using the end of the folded surface as a fulcrum, so that the operator can easily work even when the work is performed at a high place.

Further, in a state where the holding portion is inserted into the hooking hole, the holding portion restricts the vertical movement of the air supply panel, and the hooking portion is inserted into the hooking hole. In the state, the hooking portion may be configured to restrict the movement of the air supply panel in the left-right direction.

As a result, when the air supply panel is open, the holding part restricts the vertical movement of the air supply panel, and when the air supply panel is closed, the hooking part restricts the movement of the air supply panel in the left-right direction. Since the movement can be restricted, the panel does not easily come off even when a force is applied from the bottom to the top, for example.

Further, the holding portion is inclined downward from the side surface portion toward the hooking portion, and when the air supply panel is attached to the panel holding portion, the end portion of the folded surface is the upper surface of the holding portion. When placed on the surface, the structure may be such that it is guided to the bottom surface portion in the vicinity of the hooking portion along the pressing portion.

With such a configuration, when the air supply panel is attached, when the end of the folded surface is placed on the holding portion, the end of the folded surface slides along the inclined holding portion and pulls. It is guided to the bottom surface portion in the vicinity of the hanging portion. As a result, the hook portion is smoothly inserted into the hook hole, and the workability of the work of attaching the air supply panel is improved.

Further, the end portion of the holding portion on the hooking portion side may be lower than the upper end of the hooking portion.

As a result, the hook hole of the air supply panel guided along the inclined holding portion is inserted into the hook portion from above, and the air supply panel can be attached more smoothly.
