で回転させられるようになつている。Configuration of a conventional example and its problems A conventional air conditioning ventilation fan will be explained based on FIGS. 1 and 2. In the figure, 103 is an outdoor side discharge port 104 on the bottom surface and an outdoor side suction port 1 on the back side.
05, and a louver 100 is removably fitted to the front surface of the main body. The louver 100 has an indoor suction port 101 on the front surface and an indoor discharge port 1 on the top surface.
02. The indoor side suction port 101 and the outdoor side discharge port 104 communicate with each other through an exhaust passage 106, and the indoor side discharge port 102 and the outdoor side suction port 105 communicate with each other through an air supply passage 107. The exhaust passage 106 and the air supply passage 1
A heat exchange element 108 is provided at the intersection of 07,
The exhaust passage 106 has exhaust vanes 10 for blowing air.
9 is provided, and the air supply passage 107 is provided with air supply vanes 110 for blowing air. These exhaust vanes 109 and air supply vanes 110 are connected to the motor 111.
It is designed so that it can be rotated.

この時、熱交換素子108の内部で外気と室内空

気にて室内へ回収される。 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 heat exchange element 1 as shown by arrow A→A'.
08 and the main body 103 through the exhaust passage 106.
It is discharged to the outside from the outdoor side discharge port 104. The outside air sucked in from the outdoor side suction port 105 of the main body 103 flows into the air supply passage 10 as shown by arrow B→B'.
7 and the louver 10 through the heat exchange element 108.
It is discharged to the outside from the indoor discharge port 102 of No. 0.
At this time, the thermal energy of the outside 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 into the room by the outdoor air.
しかしながら上記のような構成では、熱交換素

羽根110に静圧がかかり、回転数が高く、騒音
も大きかつた。 However, in the above configuration, since there is only one heat exchange element 108, the heat transfer area is small, and the distance from the exhaust vane 109 and the air supply vane 110 is from the center of the heat exchange element 108 to both ends. There is a considerable difference in terms of surface area, and because the passing air volume is not uniform, the entire heat exchange element is not working effectively.
The amount of thermal energy recovered, that is, the heat exchange rate, was also low. In addition, the size of the heat exchange element 108 is limited due to the appearance of the product and it is difficult to increase it.
The cross-sectional area of the exhaust passageway and the air supply passageway inside the heat exchange element became smaller, the ventilation resistance loss became larger, and the ventilation air volume was also reduced. Furthermore, since the ventilation resistance loss was large, static pressure was applied to the exhaust vanes 109 and the air supply vanes 110, resulting in high rotational speed and large noise.

が悪くなる等の問題があつた。 In order to overcome these drawbacks with conventional air conditioning ventilation fans, it is possible to increase the size of the heat exchange element to increase the heat transfer area and reduce ventilation resistance loss, but this would increase the size of the main unit itself. This made installation work extremely difficult and caused problems such as poor appearance.

The present invention provides an air conditioning ventilation fan that facilitates maintenance and inspection of heat exchange elements.

D', D→D", D→D, D→D'" It is discharged indoors from the indoor side discharge port 3. At this time, the thermal energy of the outside air and the indoor air are exchanged with each other inside the four heat exchange elements 12, and the thermal energy of the indoor air is In this case, the amount of air passing through each heat exchange element (processing air volume) that performs heat exchange may be small, so the heat transfer area per unit air volume becomes large. is cut at a predetermined angle to the stacking direction of the heat exchanger plate 11 to form a right triangular column,
Since it is provided on the outer periphery of the exhaust vane 7 and the air supply vane 8, the exhaust vane 7 and the air supply vane 8
The distance from the heat exchange element 12 is the same for each heat exchange element 12, and all four heat exchange elements 12 work effectively, making it possible to increase the heat exchange rate. In addition, since each heat exchange element 12 is cut at a predetermined angle with respect to the stacking direction of the heat exchanger plates 11, the inlet area of the air from the exhaust vanes 7 and the air supply vanes 8 is reduced. Because it is large and there are four of them, ventilation resistance loss is small, a large amount of ventilation air can be obtained, and the static pressure applied to the exhaust vanes and air supply vanes is low, which lowers the rotation speed. The noise level is extremely low. In addition, since the four heat exchange elements 12 are integrally formed by the frame 15, they can be easily attached and detached from the main body 4, and maintenance and inspection such as cleaning is easy. Since the element 12 is covered, it is less likely to be scratched during cleaning, extending the life of the heat exchange element. Further, since the suction port 13 of the exhaust vane 7 is provided in the heat exchange unit 10, the depth dimension of the main body is also reduced, and the structure of the main body is also simplified, which facilitates installation work and reduces manufacturing costs.

In this case, as in the above configuration, the heat exchanger plate 1 of the heat exchange element 12
The stacking direction of the heat exchanger element 12' is vertical, and the stacking direction of the heat exchanger plates 11 of the heat exchange element 12' is horizontal, and they are arranged next to each other to prevent airflow due to the rotation of the exhaust vanes 7 and the supply air vanes 8. Heat exchange element 12,1
Since it was made to be approximately the same as the suction port direction of 2',
Air flows smoothly from the exhaust vanes 7 and the air supply vanes 8, and ventilation resistance loss is reduced, so the ventilation air volume increases and the rotational speed decreases.

揮できる。Effects of the Invention As described above, according to the present invention, a heat exchanger is provided in which a plurality of heat exchange elements are integrally formed by a frame on the outer periphery of the exhaust vane and the air supply vane provided in the center of the main body. Since the configuration is such that heat exchange ventilation is performed by providing a unit and forming an exhaust passage and an air supply passage, the heat transfer area of the heat exchange element is increased, thereby improving the heat exchange efficiency and reducing ventilation resistance loss. Since the amount of air is small, a large amount of ventilation air can be obtained, the static pressure applied to the exhaust vanes and the air supply vanes is low, and the rotational speed is also low, so noise can be extremely low. Furthermore, since the plurality of heat exchange elements are integrally formed by the frame, they can be easily attached and detached from the main body, making maintenance and inspection such as cleaning easier, and the life of the heat exchange elements is extended.
Furthermore, since the main body structure is simplified, installation work is simplified, and manufacturing costs are also reduced.
