Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heat exchange type ventilation device that recovers indoor thermal energy discharged outdoors through ventilation of a house or the like.

In recent years, as a means of ventilating a room that is being cooled or heated, the method is to exhaust dirty air from inside the room to the outside, bring in fresh air from outside, and exchange heat between the indoor air and outdoor air. Heat exchange type ventilation devices, which transfer the thermal energy of exhausted indoor air to inhaled outdoor air and recover it indoors, have come into use, and their popularity has been remarkable as homes have become more airtight.

Structure of a conventional example and its problems A conventional heat exchange type ventilation device will be explained based on FIGS. 1 to 4. In the figure, a ceiling-embedded heat exchange type ventilation system Z and a wall-embedded heat exchange type ventilation system R are shown.
are installed in separate rooms. In this ceiling-embedded heat exchange type ventilation system Z, 100 is a louver having an indoor side suction port 101 and an indoor side discharge port 102, and this louver 100 has an outdoor side discharge port 104 and an outdoor side suction port 105. A main body 10 having
3 is fitted. The main body 103 includes an exhaust passage 106 that communicates the indoor suction port 101 with the outdoor discharge port 104, and an exhaust passage 106 that communicates the indoor suction port 101 with the outdoor discharge port 104.
An air supply passage 1 that communicates with the outdoor side suction port 105
07 is formed, this exhaust passage 106 is provided with an exhaust vane 109, and this air supply passage 10 is provided with an exhaust vane 109.
7 is provided with an air supply vane 110, and a motor 111 for rotating the exhaust vane 109 and the air supply vane 110 is provided. In addition, the exhaust passage 10
6 and the air supply passage 107 have an intersection, and a heat exchange element 108 is provided at this intersection.

In the above configuration, when the exhaust vane 109 and the air supply vane 110 are rotated by the motor 111,
Indoor air sucked in from the indoor side suction port 101 of the louver 100 flows through the exhaust passage 10 as indicated by arrow A→A'.
6 and the main body 103 through the heat exchange element 108.
The outdoor air discharged to the outside from the outdoor side outlet 104 of the main body 103 and sucked in from the outdoor side suction port 105 of the main body 103 flows into the air supply passage 107 as indicated by the arrow B--→B'.
through the heat exchange element 108 to the louver 100
It is discharged to the outside from the indoor side discharge port 102. At this time, the thermal energy of the outdoor air and the indoor air are exchanged with each other inside the heat exchange element 108, and the thermal energy of the indoor air is recovered indoors.

In addition, in a wall-embedded heat exchange type ventilation system R installed in another room, 200 is the indoor suction port 2.
01 and an indoor side outlet 202, and this louver 200 is fitted into a main body 203 having an outdoor side outlet 204 and an outdoor side suction port 205. This main body 203 is formed with an exhaust passage 206 that communicates the indoor side suction port 201 with the outdoor side discharge port 204, and an air supply passage 207 that connects the indoor side discharge port 202 with the outdoor side suction port 205. The exhaust passage 206 is provided with an exhaust vane 209 , the air supply passage 207 is provided with an air supply vane 210 , and the exhaust passage 207 is provided with an air supply vane 210 .
9 and a motor 211 that rotates the air supply vane 210
is provided. Further, the exhaust passage 206 and the air supply passage 207 have an intersection, and a heat exchange element 208 is provided at this intersection. In the above configuration, when the exhaust vane 209 and the air supply vane 210 are rotated by the motor 211, the indoor air sucked in from the indoor suction port 201 of the louver 200 moves from arrow C→
Pass through the exhaust passage 206 as shown in C', and heat exchange element 2
08 and is discharged to the outside from the outdoor side outlet 204 of the main body 203, and
The outdoor air taken in from 05 is indicated by arrow D--→
The air passes through the air supply passage 207 as indicated by D', passes through the heat exchange element 208, and then reaches the indoor side discharge port 20 of the louver 200.
2 and is discharged into the room. At this time, heat exchange element 2
Thermal energy possessed by the outdoor air and indoor air are exchanged with each other inside the 08, and the thermal energy possessed by the indoor air is recovered indoors.

However, if heat exchange ventilation is to be performed in two rooms with the above configuration, a heat exchange type ventilation system must be installed in each room. 108
Since the exhaust vanes 109, the air supply vanes 110, the motor 111, etc. are incorporated into the main body 103, the dimensions of the main body 103 become large and the weight becomes heavy, making installation work very difficult. Also,
The drawback was that the ducts could not be connected after the ceiling panels were pasted, so installation work could not be carried out. In addition, since a large ceiling opening is required to install the main body 103, in the case of a rod-edge ceiling, the rod edge must be cut, which causes problems such as poor appearance and makes it difficult to clean the heat exchange element 108. In this case, since the louver 100 is large in size, it is troublesome to remove it, and it is also heavy, so there is a high risk of falling, and when replacing the main body 103, it is necessary to remove the ceiling plate, and it is necessary to replace the motor 111. When doing so, the work had to be done near the ceiling, making maintenance and inspection difficult. In addition, the motor 111 and the exhaust and air supply blades 109 and 110 are connected to the main body 103.
Because of this, noise during operation easily enters the room through the louver 100, increasing indoor noise. For wall-embedded heat exchange type ventilation system R, installation work,
Although maintenance and inspection are easy, since the louver 200 must be mounted on a wall facing outdoors, the mounting location is limited, and the louver 200 protrudes from the wall, resulting in a poor appearance.

OBJECT OF THE INVENTION The present invention solves these conventional drawbacks and facilitates the installation and maintenance inspection of a heat exchange type ventilation system when performing heat exchange ventilation for two rooms, as well as improving the appearance. The present invention provides a heat exchange type ventilation device that reduces noise.

Structure of the Invention The present invention includes a blower unit having an exhaust vane, an air supply vane, and a motor inside, and a plurality of heat exchange units having heat exchange elements inside.
The blower unit and each heat exchange unit are connected by ducts to heat exchange and ventilate multiple rooms at the same time.The main body of the blower unit is installed on the outdoor wall, the supply/discharge box is inside the wall, and the collection box is placed on the indoor wall. The heat exchange unit is removably connected to the fan unit collection box through the duct and the duct mounting plate provided on the heat exchange unit so that it can be freely removed from the indoor side through the ceiling opening. In addition to facilitating installation work, equipment replacement, and maintenance and inspection, the ceiling opening size is reduced to improve the appearance of the indoor ceiling surface and reduce indoor noise.
