Description

  The present invention relates to a ventilator.

  Conventionally, as a ventilation device attached to a ventilation hole provided on a wall surface of a building to be ventilated, a ventilation device having an opening / closing function capable of switching between a ventilation enabled state and a ventilation disabled state has been proposed.

  Originally, this ventilator is required to be able to ventilate the inside and outside of the room at all times due to the relationship with the Building Standards Law, but on the other hand, it is open, for example, during typhoons and strong winds. However, there is also a demand to make the ventilation impossible in an unavoidable situation where inconvenience arises.

  This ventilating device with an opening / closing function comprises a cylindrical mounting body connected to a ventilation hole, and an opening / closing lid provided at the front opening of the mounting body for opening / closing the front opening. In general, it is possible to switch between a closed position and an open position by pushing the button.

  By the way, this type of ventilator with an opening / closing function has been proposed that includes an opening / closing mechanism that switches the position of the opening / closing lid (a plurality of positions of a closed position, an opening position, and a maximum opening position) in stages. (Hereinafter referred to as a conventional example).

  In this conventional example, by switching the opening / closing position of the opening / closing lid, the degree of opening of the front opening of the mounting body can be varied to adjust the air flow rate.

  In the conventional example, the opening and closing lid body is opened and closed in the order of the opening position to the closing position, the closing position to the opening position, and the opening position to the opening position. Switching is most necessary. That is, it is most necessary in daily life if you do not want to block the ventilation but want to restrict it.

  Nevertheless, the conventional example is extremely troublesome because it cannot achieve the opening halfway position unless it passes through the closing position from the opening position.

  In addition, in the conventional example, the mounting structure of the opening / closing lid body with respect to the mounting body is generally a structure in which parts are mounted from the rear side of the mounting body, and it is necessary to replace the parts after installation on the wall surface. In such a case, there is a problem that the maintainability is very bad, for example, the entire apparatus (mounting body) must be removed from the wall surface.

  The present invention has been developed in view of the above-described problems, and provides a ventilation device that is very easy to operate and excellent in practicality.

  The gist of the present invention will be described with reference to the accompanying drawings.
