Description

  The present invention relates to a heat exchange ventilator capable of performing ventilation by supply / exhaust while exchanging heat between supply / exhaust flows through a built-in heat exchanger.

  The heat exchange ventilator incorporates a heat exchanger that performs air-to-air heat exchange, and performs ventilation by simultaneous supply and exhaust while performing heat exchange.

  For example, Patent Document 1 discloses a heat exchange ventilator embedded and installed in the back of a ceiling in which an air supply blower and an exhaust blower are arranged with a heat exchanger interposed therebetween.

  Since this type of embedded heat exchange ventilator is completely embedded in the back of the ceiling, it is difficult to secure space for maintenance of the heat exchange ventilator on the upper and lower surfaces of the product. Therefore, it is configured so that maintenance can be performed from the side of the product. When a sirocco fan is used for the blower, a structure is adopted in which the scroll casing of the blower is formed integrally with the air passage on the main body side, and a motor with blades is attached thereto, thereby completing the blower and the air passage.

  Further, the rotating shaft of the blade member of the blower, that is, the rotating shaft of the motor is provided so as to be horizontal with respect to the bottom surface of the casing so that the blower can be easily attached and detached from the maintenance port on the side surface of the product during maintenance. As a result, the blade member can be easily inserted into and removed from the scroll casing, and the heat exchanger is removed from the maintenance port only for the blower ASSY (a state in which the blade and the motor are integrated) without removing the scroll casing. Later, the product can be removed horizontally in the opening space in the product, and sufficient maintenance is possible even in a space-saving maintenance space behind the ceiling.

  Patent Document 2 discloses a heat exchange ventilator installed and used on a floor in a building, in which a supply air blower and an exhaust blower are arranged with a heat exchanger interposed therebetween.

  In this type of floor-mounted heat exchange ventilator, the blower may be detachable from the front or rear surface of the main body so that the blower can be maintained or replaced. For example, a pair of guide rails are provided in parallel to the front side and the rear side inside the main body of the heat exchange ventilator, and a blower is inserted on the guide rails. The blower slides toward the rear side of the main body along the guide rail, and is fixed to a stopper provided on the rear side of the main body or the rear end of the guide rail.

JP-A-9-133386 (see, for example, [0014] to [0023]) JP 2012-78063 A (see, for example, [0011] to [0035])

However, in the embedded heat exchange ventilator as disclosed in Patent Document 1, during maintenance of each blower, first, the maintenance port opened on the exterior of the product is removed, the heat exchanger is taken out, and then the arm from the above maintenance port. Or, it was necessary to immerse the entire body in the product, remove the screw around the blower, and take out the heavy blower with one hand. Therefore, although the work was easy, it was hard labor.
In addition, the blowout port portion, which is a large opening opened in the exterior, is a portion that is weak in strength and has a structure that should not be deformed. However, in the heat exchange ventilator as shown in Patent Document 1, There are no parts to reinforce it.

Moreover, in the floor-mounted heat exchange ventilator like patent document 2, although there exists a slide structure of an air blower, it is a floor-standing type and a ceiling embedding is impossible. Even if it can be embedded in the ceiling, it has a structure where the take-out position of the air supply blower and the exhaust blower are largely separated and pulled out from the position corresponding to each blower, so usually one maintenance provided on the ceiling Both hands are out of reach during the maintenance work from the mouth.
Therefore, it is necessary to provide a maintenance port in the ceiling according to the position of each blower, and there is a problem that the design of the ceiling is impaired.

  The present invention has been made in view of the above, and an object of the present invention is to obtain an embedded heat exchange ventilator that realizes ease of maintenance.
