Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a heat exchanger extraction device for a heat exchange type ventilation system that recovers indoor thermal energy that is discharged outdoors through ventilation.

BACKGROUND TECHNOLOGY Conventionally, this type of heat exchange type ventilation system has been used, for example, in order to exchange heat between indoor and outdoor air, as shown in Figs.
The first, second, and third heat exchangers 101A, 101B, and 101C each having a rectangular prism shape tilted at 45 degrees are connected to the main body 10.
They can be taken out individually in the horizontal direction from an opening 104 in a side plate 103 of No. 2.

Problems to be solved by the invention In this conventional configuration, the first, second, and third
When taking out the heat exchangers 101A, 101B, and 101C from the opening 104 of the main body 102, even if the first heat exchanger 101A on the front side can be taken out easily,
Second and third heat exchangers 101B and 101C on the back side
The problem was that they were hard to reach and could only be removed using special tools.

The present invention has been made with the above-mentioned conventional problems in mind, and an object of the present invention is to provide a heat exchange type ventilation device in which the heat exchanger can be easily maintained and inspected.

Means for Solving the Problem In order to solve this problem, the present invention includes a plurality of heat exchangers arranged in series, a blower for sucking outside air, a blower for discharging indoor air, and a main body incorporating these. , an opening slightly larger than the heat exchanger provided in the side plate of the main body, and a connector for connecting one end and the other end of the plurality of heat exchangers, at least one of the connectors. The end has a detachable fixed part.

Effect With this configuration, the heat exchanger can be removed by removing the fixing part of the front heat exchanger, taking out the front heat exchanger, and then pulling the connector. Because it is located at the front, the heat exchanger on the back side also has to be removed from the front without having to reach all the way into the main body.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is the main body of the heat exchange type ventilation device, which is provided with an indoor suction port 2 and an indoor discharge port 3 communicating with the room on one side, and an outdoor suction port 4 communicating with the outdoors and the indoor side suction port 4 on the other side. An outer discharge port 5 is provided. Inside this main body 1, first, second, and third heat exchangers 6a, 6b, and 6c for exchanging heat between indoor and outdoor air are arranged in series in the horizontal direction, and 7a and 7b are arranged on the front side, respectively. , the first handle of 7c,
Second handles 7x, 7y, and 7z are provided on the back side. A blower 8 for sucking in outside air is provided in the air passage leading to the outdoor suction port 4, and a blower 9 for discharging indoor air is provided in the air passage leading to the indoor suction port 2. The side plate 11 of the main body 1 has the heat exchangers 6a, 6b,
Heat exchangers 6a, 6b, 6 slightly larger than 6c
c. An opening 10 for taking out is provided, and a closing plate 12 is provided in this opening 10. In addition,
A closing plate 12a is also provided at a symmetrical position on the opposite side. The first handle 7a on the front side of the first heat exchanger 6a and the second handle 7z on the back side of the third heat exchanger 6c have fixing parts 13 such as hook-and-loop fasteners attached at both ends. and a connecting member 14 such as a belt provided with a fixing portion 13a on the opposite side.

In the above configuration, the first, second, and third heat exchangers 6a, 6b, and 6c are taken out as follows.

In the above configuration, the first, second, and third heat exchangers 6a, 6b, and 6c are taken out as follows.

Remove the fixing part 13 of the connector 14 fixed to the first handle 7a of the first heat exchanger 6a, and
Pull out the heat exchanger 6a, and then pull the connector 14 to move the second and third heat exchangers 6a and 6c to the front and take them out.

As described above, according to this embodiment, the first, second,
When taking out the third heat exchangers 6a, 6b, 6c from the opening 10, the second and third heat exchangers 6b, 6c located at the back can be positioned as far as the front by pulling the connector. As with the heat exchanger 6a of No. 1, it is taken out near the opening 10, and can be easily taken out from the main body 1.

In this embodiment, each heat exchanger 6a, 6b, 6c was explained as being taken out from the closing plate 12 side.
It goes without saying that depending on the position of the inspection hole provided in the ceiling, it can be taken out in the same way even if it is accessed from the blocking plate 12a on the opposite side.

Effects of the Invention As is clear from the description of the embodiments described above, according to the present invention, a connecting device connects one end and the other end of a plurality of heat exchangers, and at least one end is a detachable fixture, By pulling this connector, the heat exchanger located at the back of the main unit can be pulled out, so you don't have to reach deep into it or use special tools to remove it. There is no need to use it, it can be taken out near the opening, and the effect is that the heat exchanger can be easily maintained and inspected.
