Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchange ventilator for performing ventilation by supply and exhaust while exchanging heat between supply and exhaust flows through a built-in heat exchanger.

[0002]

2. Description of the Related Art This type of heat exchange ventilator has a built-in heat exchanger for performing heat exchange between air and air, and performs ventilation by simultaneous air supply and exhaust while performing heat exchange. Ventilation with little fluctuation in volume can be performed. As such a heat exchange ventilator, a stacked heat exchanger configured in a hexahedron is widely used. The end face of the heat exchanger has a parallelogram shape.
As shown in JP-A-178238 and JP-A-2-267442, two diagonal lines related to the fore-edge are assembled in a box-shaped main body casing such that one of the two diagonal lines is oriented in the horizontal direction and the other is oriented in the vertical direction. ing. Therefore, the primary passage for passing the exhaust flow of the heat exchanger and the secondary passage for passing the supply air flow obliquely intersect. In the main body casing, an exhaust air passage for passing an exhaust air flow and an air supply air passage for passing an air supply flow are defined independently over the entire path. However, the air passage configuration is quite complicated and assembly is not good.

Therefore, an air supply passage 50 as shown in FIG.
An air supply-side airflow component 55 integrally formed with an outlet portion 51 leading to an outlet end of the air outlet, an inlet portion 53 following an inlet end of the exhaust air passage 52, and a blower casing portion 54, and an outlet end of the exhaust air passage 52 An exhaust-side air path component 56 integrally formed with an outlet section 51, an inlet section 53 following the inlet end of the supply air passage 50, and a blower casing section 54 is mounted on the opposite side in the main body casing 57, and A part in which the supply air passage 50 and the exhaust air passage 52 are integrally formed by integral molding has also been developed. The supply-side air path component 55 and the exhaust-side air path component 56 have the same configuration and are assembled in a rotationally symmetric relationship. The portion from the blower casing portion 54 to the outlet portion 51 of the supply-side air path component 55 and the exhaust-side air path component 56 is oriented in a right angle direction with an R-shaped surface so as not to have a large resistance.

[0004]

In the conventional heat exchange ventilator as described above, the configuration employing the air supply side air path part 55 and the exhaust side air path part 56 reduces the number of parts and reduces the weight. Although it is possible to achieve the improvement of the efficiency and the assembling property, and the production effectiveness is high, the positions of the inlet / outlet end of the supply air passage 50 and the inlet / outlet end of the exhaust air passage 52 are set to the supply air passage part 55 and the exhaust air passage. It is determined by the configuration of the outlet portion 51 of the part 56, and the body casing 5
7 has a problem that it is difficult to set the entrance end in multiple directions. In addition, since the outlet portion 51 of the supply-side air path component 55 and the exhaust-side air path component 56 has an R-shaped surface, there is also a problem that it is difficult to manufacture a mold and the cost is high.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a heat exchange ventilator using air supply and exhaust side air path components. To increase the degree of freedom regarding the duct piping of
