Description

  The present invention relates to a structure for opening and closing a front panel of a ventilator, and more particularly to a ventilator having a front panel that can be opened and closed both vertically and horizontally and detachable from a body case.

  Ventilation devices such as a ventilation fan and a heat exchange type ventilation fan require periodic removal of the front panel due to the need for maintenance such as cleaning. Since a ventilator is generally installed on a wall or the like near the ceiling, the front panel removal work is often performed on a stepladder or ladder. For this reason, it is desirable that the front panel of the ventilation device can be easily removed.

  In order to facilitate the removal of the front panel, the following proposals have been conventionally made. In other words, a front panel is provided for the main body that houses the ventilation equipment, with a shape that covers the front of the main body, with the upper part serving as a fulcrum, and is openable and detachable. Are provided, and long shaft holes are provided on the left and right sides of the front surface side of the main body in front and rear directions obliquely upward and engaged with the rotation shaft of the front panel. Thereby, when the front panel is opened, the front panel can be removed without contacting the main body (see, for example, Patent Document 1).

  FIG. 14 is a schematic diagram showing how the front panel of the ventilation device described in Patent Document 1 is opened and closed. In the proposed ventilator, the rotation axis of the front panel 150 is removed from the main body 160 with the front panel 150 opened upward with respect to the main body 160. However, in general, the ventilator is often installed on a vertical wall 210 close to the ceiling 200 or a vertical surface close to a lateral wall (not shown) as shown in FIG. In such a case, the front panel 150 contacts the ceiling 200 and cannot be removed. In particular, when the front panel 150 has an air inlet and an air outlet and has a large thickness in the depth direction, a predetermined distance from the ceiling 200 is required.

  Furthermore, in the ventilator described in Patent Document 1, after the front panel is opened upward, the pivot shaft of the front panel is removed from the main body 160, so that the work is performed at a high position and the workability is poor. In addition, since the front panel 150 may be dropped, improvement has been demanded.

  The present invention has been made to solve the above-described problems. The front panel can be double-opened, the front panel can be opened and closed in a direction that does not interfere with the wall surface, and in any direction in any direction. It is an object of the present invention to provide a ventilator that can easily remove a front panel even if it is installed, and does not cause the front panel to fall, thereby facilitating maintenance work.

In order to solve the above problems, a ventilator according to the present invention is provided to cover a front surface of a main body case by forming a ventilator, a main body case for housing the ventilator, an air inlet and an air outlet. and a front panel, and the engagement portion respectively provided on either one of the four corners of the main body case and the front panel, a forward direction relative to the engagement portion respectively provided on the other corners corresponding to the engagement portion And an engaged portion that is detachably and rotatably engageable.

  In the ventilator according to the present invention, the engaging portion includes an arm portion and a bulging portion formed at the tip of the arm portion, and the engaged portion rotates the bulging portion with a predetermined force. It is characterized by including an elastic pivot part that pivots freely and opens the bulging part when a predetermined force or more is applied.

  Here, the ventilation device includes not only those that exchange indoor and outdoor air, but also those that ventilate indoor air, those that circulate indoor air, and the like. Including air conditioners.

Further , the “ bulged portion” means a swollen shape, that is, a shape having a larger outer diameter than the arm portion is provided at the tip of the arm portion.

  According to the ventilator according to the present invention, the engagement portions provided at both ends of either the main body case or the front panel and the engagement portions provided at the other engagement portions of the main body case and the front panel are provided. Since it has an engaged part that is detachable in the forward direction with respect to the joint part and engages in a freely rotatable manner, either the engaging part or the engaged part provided at both ends is selected and opened. By doing so, the front panel can be double-opened. As a result, the front panel can be opened and closed in a direction that does not interfere with the wall surface, so that it can be installed in any direction in any direction. Moreover, if the front panel is opened, the front panel will not be dropped. On the other hand, by opening both engaging portions and engaged portions provided at both ends, the front panel can be easily removed forward, and maintenance work can be facilitated.
