Description

  The present invention relates to a ventilator that is mainly used in the field of ventilation and ventilates a room while exchanging heat between indoor air and outdoor air using a heat exchanger.

  More than 40 years have passed since the start of the sales of ventilators equipped with heat exchangers, and there are many cases in the market where the ventilators are replaced in conjunction with the replacement of air conditioning equipment accompanying the renewal of buildings.

  In addition to improving heat exchange efficiency, current ventilation systems have improved ventilation performance, enabling more reliable ventilation. Accordingly, the size of the ventilator is different from that of the past ventilator, and the pitch of the suspension bolt for hanging from the ceiling is not necessarily the same. Also, there are cases where the air volume is different, and it is necessary to replace the suspension bolts at the time of renewal.

  Conventionally, as a ventilation device using existing suspension bolts, when installing the main body of the ventilator in the horizontally long state, a hanging bracket is directly attached to the horizontal dimension opposite surface of the main body, and when installing the main body in the vertically long state, the vertical dimension of the main body There is one in which a hanging metal fitting is attached to the opposite surface via an auxiliary metal fitting (for example, see Patent Document 1).

JP-A-10-246488 (summary)

  In the conventional ventilator described above, the suspension fittings are installed at the four corners of the main body, and the main body is suspended by four suspension bolts. In recent years, renewal has been carried out on existing properties due to the renewal of air conditioners etc., and there are many cases where new ventilators of different sizes are installed in the places where existing ventilators were installed It has become. When installing ventilators of different sizes, there is usually only one existing hanging bolt that can be used, and the remaining three need to be cut or pulled out of the way. Yes. When one hanging bolt is used, it is necessary to newly install three hanging bolts. The reworking of the suspension bolt due to the fact that the ceiling suspension pitch does not match is one factor that increases the construction period and construction cost.

  The present invention was made in order to solve the above-described problems. By diverting existing suspension bolts as much as possible, it is possible to reduce the construction period, construction cost, and waste such as existing suspension bolts. The aim is to obtain a ventilator that can.

  The ventilation apparatus according to the present invention includes a heat exchanger, an air supply fan that sucks outdoor air and blows the air into the room through the heat exchanger, and an exhaust fan that sucks indoor air and discharges the air through the heat exchanger. It has a box-shaped main body inside and two sets of support fittings provided respectively in the front and rear of the air flow direction of the main body, and the two sets of support fittings are respectively provided on both side surfaces of the main body in the air flow direction. A first support member provided oppositely, a second support member provided between the opposing first support members and movable in the direction of airflow, and a second support member orthogonal to the direction of airflow And a third support member fixed to a suspension bolt suspended from the floor slab on the upper floor.

  According to this invention, the two sets of support fittings provided on the main body are provided so as to be movable in the direction perpendicular to the direction of the air flow, on the second support member, which is movable in the direction of the air flow. And a third support member fixed to a suspension bolt suspended from the floor slab on the upper floor. With this configuration, the ventilation device can be suspended without installing the suspension bolt in accordance with the size of the ventilation device. This makes it possible to divert existing suspension bolts, especially when renewing ventilation equipment, and can reduce the work period and construction costs compared to ventilation equipment that requires replacement of suspension bolts. Waste such as bolts can be reduced.

The perspective view of the ventilator which concerns on embodiment of this invention. The perspective view which shows the modification of the support metal fitting provided in the ventilation apparatus of FIG. The perspective view which shows the modification of the support metal fitting provided in the ventilation apparatus of FIG.

  Embodiments of a ventilator according to the present invention will be described below in detail with reference to the drawings. In addition, this invention is not limited by this embodiment.

FIG. 1 is a perspective view of a ventilation device according to an embodiment of the present invention.
The ventilator 1 shown in FIG. 1 is provided in front of and behind the box-shaped main body 10 having a heat exchanger, an air supply blower, and an exhaust blower inside, a control box 17, and an air flow direction of the upper surface 18 of the main body 10, respectively. And two sets of supporting brackets 20 are provided. The main body 10 is formed in a rectangular parallelepiped shape whose outer shape is long in the direction of airflow (depth direction), for example.

  An outdoor air supply port 12 and an outdoor exhaust port 13 are provided on one surface 11 in the depth direction of the main body 10. On the other surface 14, an indoor air supply port is provided at a position diagonally with respect to the outdoor air supply port 12, and an indoor exhaust port is provided at a position diagonally with respect to the outdoor exhaust port 13. . The outdoor air inlet 12 and the indoor air inlet communicate with each other via an air supply air passage formed in the main body 10, and the outdoor air outlet 13 and the indoor air outlet are formed in an exhaust air air passage formed in the main body 10. It communicates through.

  The heat exchanger is installed at the intersection of the supply air passage and the exhaust air passage. The air supply blower is installed in the supply air passage on the indoor air supply port side, and the exhaust air blower is installed in the exhaust air passage on the outdoor exhaust port side.
