Description

[Detailed description of the invention] This invention relates to an improvement of a ventilation system that performs heat exchange between exhaust air from indoors and intake air from outdoors.

In conventional ventilation systems of this type, the exhaust fan that supplies indoor air to the heat exchanger and the intake fan that supplies outdoor air are attached to rotating shafts that extend to both sides of the electric motor, and the rotating shaft is aligned with the wall surface. Because it was placed at right angles, the device protruded into the room.
There was a drawback that it spoiled the interior view.

This invention aims to improve the above-mentioned drawbacks of the conventional ventilation system.It is a ventilation system that reduces the depth by arranging an exhaust fan and an intake fan in parallel, each driven by a dedicated electric motor. It provides:

An embodiment of this invention will be described below with reference to FIGS. 1 to 5. In the figure, 1 is a heat exchanger formed by alternately stacking exhaust passages and intake passages (both not shown); 2 is an exhaust fan that sucks indoor air and supplies it to the exhaust passage of the heat exchanger 1; 3 is an intake fan that sucks outdoor air and supplies it to the intake path of the heat exchanger 1; 4 is an exhaust electric motor that drives the exhaust fan 2;
Reference numeral 5 denotes an intake electric motor that drives the intake fan 3. Reference numeral 6 denotes an outer housing that houses a heat exchanger 1, an exhaust fan 2, an intake fan 3, etc., and is composed of a front outer box 7 and a rear outer box 8 made of plastic. The box, the front outer box 7 is integrally formed with an exhaust casing 7a that guides the exhaust air from the exhaust fan 2 shown by the arrow A to the exhaust path of the heat exchanger 1, and the rear outer box 8 is shown by the arrow A from the intake fan 3. An intake casing 8a that guides intake air indicated by B to an intake passage of the heat exchanger 1 and a mounting portion 8b for mounting the exhaust motor 4 are integrally formed. A partition plate 9 is fixed between the front outer box 7 and the rear outer box 8, supports the intake electric motor 5, and separates the exhaust air from the exhaust fan 2 and the intake air from the intake fan 3. The outer wall to be attached, 11 penetrates the outer wall 10, and an exhaust path for discharging the exhaust gas that has passed through the heat exchanger 1 outdoors, 12 penetrates the outer wall 10,
Intake path 1 that supplies outdoor air to intake fan 3
3 and 14 are weather covers that respectively cover the exhaust pipe 11 and the intake pipe 12 to prevent raindrops from entering the apparatus; 13a is an exhaust port; and 14a is an intake port.

With the above structure, by operating the exhaust fan 2 and the intake fan 3, indoor polluted air is sucked in from the suction port 6a of the outer box 6, guided to the exhaust casing 7a, and introduced into the exhaust path of the heat exchanger 1. The weather cover 14 provides fresh air and outdoor fresh air.
is sucked from the intake port 14a of the intake casing 8.
a and is supplied to the intake passage of the heat exchanger 1,
During heating in winter, low-temperature intake air from outside is warmed by exhaust air from indoors in the heat exchanger 1.
The air is supplied into the room from the air intake port 6a of the outer box 6.

Furthermore, during cooling in the summer, high-temperature intake air drawn from outside is cooled in the heat exchanger 1 by low-temperature exhaust air from indoors and supplied indoors, and in either case, energy is used effectively.

As mentioned above, the function of this device as a ventilation device is the same as the conventional one, but the exhaust fan and intake fan are driven by their own electric motors, and are arranged in parallel to the wall surface. Therefore, the depth dimension is approximately 60 mm compared to the vertical one.
%, and can be made thinner, so the interior appearance can be improved. Furthermore, since the exhaust casing and the intake casing are integrated with the front and rear casings, the number of parts is reduced and assembly is facilitated, leading to improved productivity.
