Description

The present invention relates to a ventilator that supplies air outside a building to the room and exhausts air inside the building to the outside of the building.

  Conventionally, a heat exchange type ventilator that supplies fresh outside air to each room with a heat exchange unit close to the room temperature, and exchanges the dirty air in the room with the heat exchange unit and discharges it outdoors. Has been. In recent years, all buildings having living rooms are obliged to install a 24-hour ventilation facility, and the demand for heat exchange type ventilators is increasing.

  The heat exchange ventilator has an intake port for taking outside air into the side wall portion of the main body case, an intake port for supplying the intake air into the room, and an intake port for taking in the air from the room. And an exhaust port for discharging the air sucked into the room from the suction port to the outside. A motor having rotating shafts for an air supply fan and an exhaust fan is installed inside the main body case. An air supply fan and an exhaust fan are attached to each of the rotation shafts of the motor. As a result, an air supply air passage through which fresh air taken from the outside is supplied indoors and an exhaust air passage that sucks indoor dirty air and sends it out to the outside are formed inside the main body case. A heat exchange element for exchanging heat between the air blown from the supply fan and the air sucked by the exhaust fan is provided at the intersection of the supply air path and the exhaust air path (see Patent Document 1).

  In the heat exchange type ventilator configured in this way, condensation is formed inside the main body case due to cold outside air taken in from outside in the winter or the temperature difference between the room where the air supply fan is installed and the room where the exhaust fan is installed. May occur. In particular, condensation is likely to occur in a room where a heat exchange element is installed. Therefore, as a countermeasure against condensation, a heat exchange type ventilator that employs a main body case formed of a foamed resin such as polystyrene foam is used. As a result, even if low-temperature air is supplied to the inside of the main body case that houses the air supply fan, dew condensation is prevented by the heat insulating effect of the foamed resin material.

JP 2007-24415 A

  However, the heat exchange ventilator disclosed in Patent Document 1 has the following problems.

  The polystyrene foam constituting the main body case is generally light in weight and excellent in heat insulation, but has a characteristic that strength is low. For this reason, the foamed polystyrene may be deformed by a load (pressure) of a fan, a heat exchange element, or the like. As a result, the air direction of the air supply and exhaust air passages, which serve as air passages, is disturbed, and there is a problem that heat exchange and ventilation cannot be performed smoothly and efficiently. Furthermore, it is desired to prevent condensation in the supply air passage and the exhaust air passage while improving the strength of the main body case.

  Therefore, the present invention solves the above-described problems, and an object thereof is to provide a ventilator that improves the strength of the ventilator body of the ventilator and prevents condensation.

  In order to solve the above problems, a ventilating apparatus according to the present invention takes in air outside a building from an intake port and supplies the intake air into the room from the intake port, and inhales from the intake port. A ventilator main body having an exhaust air passage for exhausting indoor air from the exhaust port to the outside of the building, and provided inside the ventilator main body, and rotationally driven by driving means to exhaust the air outside the building to the indoor An air supply fan to be supplied to the exhaust system, an exhaust fan provided inside the ventilation device main body, which is rotationally driven by a driving means and sucks the indoor air through the suction port, the air supply air path, and the exhaust air A heat exchanging means for exchanging heat between the air taken in from the intake port and the air drawn in from the intake port, and a resin material that supports at least a part of the heat exchange means Or And a made supporting member, wherein the support member constitutes a part of said exhaust air passage.

  In the present invention, the support member is made of a resin material, and the resin material has a characteristic of high strength. Therefore, it is possible to prevent the support member from being deformed by heat exchange means or the like, and it is possible to form an exhaust air passage that is not disturbed. In addition, since the resin material is generally excellent in heat insulating properties, it is possible to prevent dew condensation caused by heat exchange means or the like even when a part of the exhaust air passage is formed by the support member.

  According to the present invention, by configuring the support member that supports the heat exchange element with a high-strength resin material, it is possible to improve the strength of the support member and prevent deformation of the support member. In addition, since the resin material has a heat insulating property, it is possible to prevent condensation generated by the heat exchange means.
