Description

  The present invention relates to a ventilation device.

  Conventionally, as this type of ventilator, there is known a ventilator that is installed in a building, introduces outside air from an outside air supply port, and supplies the outside through a built-in heat exchanger (see, for example, Patent Document 1). ).

  Hereinafter, the ventilation air conditioner will be described with reference to FIG.

  As shown in FIG. 12, the outer casing 101 is installed in a ceiling space in a building. A lower panel 103 is attached below the outer casing 101 via a panel outer frame. Fresh outside air is introduced from the air supply port, and passes through the air supply ventilation path 114b supplied to the room through the panel outlet UO. On the other hand, dirty air in the room is introduced from the panel suction port UI and passes through the exhaust ventilation path 114a exhausted from the exhaust port to the outside of the room. The heat exchanger 109 is configured to perform heat exchange between the exhaust flow A1 exhausted from the exhaust port and the supply air flow B1 supplied from the air supply port.

  The ventilator according to the present invention includes a box-shaped main body, a louver provided below the main body, an air supply fan provided in the main body, and an exhaust fan. Includes an air supply panel, an air pressure panel, a panel holding portion, a louver frame, and an inspection panel, and the air supply panel and the air pressure panel are held by the louver frame by the panel holding portion, and the louver frame has an inspection opening. The inspection panel is provided in the inspection opening, and the louver has an air supply port on the air supply panel side, an air supply port on the air circulation panel side, an outside air port on the side surface of the main body, and An exhaust port is provided, and a supply air passage is formed by which the outdoor air is blown from the outside air port to the air supply port by the supply air blower, and the exhaust port from the ring air port to the exhaust port An exhaust air passage through which indoor air is blown is formed, the panel holding portion includes a side surface portion, a bottom surface portion, a hooking portion, and a pressing portion, and the side surface portion is connected to the louver frame, and the bottom surface portion Is connected to the side surface portion, the hook portion is provided to protrude upward from the bottom surface portion, and the pressing portion is provided to protrude from the side surface portion to the hook portion, The air supply panel 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, The bent portion connects the front portion and the folded portion, the folded portion is provided so as to be folded in a direction overlapping the front portion, and a hooking hole into which the pressing portion and the hook portion are inserted is provided. Have said air supply When the air channel is open, the air supply panel is in a state in which the pressing portion is inserted into the hooking hole, and when the air supply panel is closed, the air supply panel It is a ventilator which becomes a state inserted in a hook hole.

  Thereby, 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 hooking hole, and when the air supply panel is closed, the air supply panel is The hooking portion is held in the panel holding portion by being inserted into the hooking hole. As a result, the panel can be easily detached and workability is improved.

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

  With this 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 with the end of the folded surface coming into contact with the bottom surface portion. When the air supply panel is closed, such as when air is supplied, the air supply panel is supported by the bottom surface portion by the close contact between the folded surface and the bottom surface portion.

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

  As a result, when the air supply panel is open, movement of the air supply panel in the vertical direction is restricted by the pressing portion, and when the air supply panel is closed, the hooking portion is used to move the air supply panel in the left-right direction. Since the movement can be limited, for example, even when a force is applied from the bottom to the top, the panel is unlikely to come off.

  The pressing portion is inclined downward from the side surface portion toward the hook portion, and when the air supply panel is attached to the panel holding portion, an end portion of the folded surface is an upper surface of the pressing portion. It is good also as a structure guided to the said bottom face part in the vicinity of the said hook part along the said pressing part.

  With this configuration, when the air supply panel is attached, if the end of the folded surface is placed on the holding part, the end of the folded surface moves so as to slide along the inclined holding part. Guided to the bottom surface in the vicinity of the hook. Thereby, a hook part is smoothly inserted in a hook hole, and the workability | operativity of the operation | work which attaches an air supply panel improves.

  Moreover, it is good also as a structure where the edge part in the said hook part side of the said press part is lower than the upper end of the said hook part.

  Thereby, the hooking hole of the air supply panel guided along the inclined pressing part is inserted into the hooking part from above, and the air supply panel can be attached more smoothly.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
