Description

  The present invention relates to a ventilating device attached to a ventilating opening so as to communicate with a ventilating duct disposed in, for example, a ceiling, a wall or the like in a ventilator in a store, an office, an apartment, or the like.

  Conventionally, in air conditioners in stores, offices, condominiums, etc., for example, a ventilation duct is installed on the back of the ceiling, and a louver panel equipped with a filter is attached to the ventilation opening that leads to the ventilation duct. It removes and captures dust and other substances in the air to ventilate the interior of the store.

  Accompanying the operation of the air conditioner, not only replacement of the filter but also maintenance such as cleaning and inspection inside the ventilation duct is necessary due to contamination and damage of each part of the apparatus constituent members. For example, if dirt or dust such as oil or cigarette accumulates inside the ventilation duct, it may cause a decrease in ventilation power. Therefore, the air conditioning apparatus can be used safely and comfortably by periodically cleaning the ventilation duct.

  By the way, for the inspection of the air conditioner, etc., for example, a ventilation opening device is provided in a ventilation opening formed in a ceiling surface, a wall surface, etc., and a ventilation louver panel provided with a filter in this ventilation opening device is provided. As an open / close device that opens and closes, for example, there is a ventilating device for ventilation proposed in Patent Document 1. This ventilation device can be applied to a case where ventilation with an air-conditioning ventilation system or a natural ventilation system is applied, and can be applied without problems even under use conditions where a sufficient waterproof function is required. The filter disposed inside can be easily replaced from the outer surface side of the housing.

  That is, the ventilation device for ventilation disclosed in Patent Document 1 includes a base frame that is fixed to the outer surface of the mounting opening, a louver panel that closes a vent opening in the base frame, and air that is attached to the base frame and enters from the louver panel. It is equipped with an air guide box that guides it upward and a dustproof filter.

  In addition, an inverted J-shaped latching groove is formed at the lower end of the louver panel, and by engaging this latching groove with the shaft of the base frame, the louver panel is pivotally supported, Therefore, it is possible to swing upward and open between a closed position for closing the vent and an open position. Moreover, since the louver panel is pivotally supported through the latching groove with the lower end portion opened in this way, the louver panel can be removed from the base frame and its inner surface can be cleaned.

  Further, a screw-like stopper for fixing and holding the louver panel and a stopper for receiving the louver panel at the open position are provided between the louver panel and the base frame. According to Patent Document 1, the filter can be taken in and out from above with respect to a guide frame provided on the inner surface of the louver panel in a state where the louver panel is opened.

Utility Model Registration No. 3202467

  However, in the case of the above-described Patent Document 1, when cleaning the inside of the vent hole or the inner surface of the louver panel, the retaining groove of the louver panel must be removed from the shaft of the base frame, and cleaning, inspection, etc. Maintenance work is very troublesome.

  Further, when the ventilating device for ventilation according to Patent Document 1 described above is installed in the ventilation opening that leads to the ventilation duct, the retaining groove of the louver panel is instantly opened when the louver panel is swung downward and the vent is opened. There is a risk that the louver panel easily falls off the shaft of the base frame and falls and breaks.

  In addition, since the louver panel does not have a mechanism for supporting the filter in advance, there is a possibility that the filter may accidentally slide and drop from the louver panel at the moment when the louver panel is swung downward.

  Furthermore, there is a risk that a screw-like stopper loosened to open the louver panel may be accidentally dropped and lost.

  Therefore, the present invention was devised in view of the existing circumstances as described above, and its purpose is, for example, to install a louver panel attached to a ventilation opening that leads to a ventilation duct arranged on the back of a ceiling, a wall surface or the like. By making it easier to open and close the louver panel without having to remove it, you can easily perform maintenance such as cleaning the inner surface of the louver panel, replacing the filter, and cleaning and checking the inside of the ventilation duct. In addition, it is an object of the present invention to provide a ventilating device that can be securely and easily closed with a simple structure by locking and closing the louver panel in a closed position and opening the louver panel by releasing the lock.
