DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present embodiment shown in FIGS. 1 to 6 relates to an exploded structure in a heat exchange ventilator as an example of electric equipment. In this heat exchange ventilator, a heat exchanger 1 for performing air-to-air heat exchange is built in a main body box 2 configured in a hexahedral box shape, and performs simultaneous heat supply and exhaust while performing heat exchange. This is to perform indoor ventilation, and it is possible to perform ventilation with little variation in the state quantity in the room. In the main body box 2, a part of the path is constituted by one fluid passage of the heat exchanger 1, and an air supply passage 4 through which an air flow from the outdoor to the indoor is passed by the air supply blower 3, and a part of the path Is constituted by the other fluid passage of the heat exchanger 1, and an exhaust passage 6 through which an air flow from the room to the outside is passed by the exhaust blower 5 is independently defined over the entire path.

The main body box 2 is made of a thin steel plate, and a guide rail-shaped heat exchanger attaching / detaching structure 7 is provided as shown in FIG.
Further, in order to increase the rigidity of the main body box 2, ribs 8 formed by drawing are provided at important points as shown in FIG. The heat exchanger attachment / detachment structure 7 has a configuration in which a flat bottom channel is formed in the center by rising on both sides protruding inward. The heat exchanger 1 is formed in a stacked hexahedron shape, and the rectangular holding frames 9 at two opposing ridges are inserted into and removed from the channels of the heat exchanger attaching / detaching structure 7 above and below the main body 2. Can be attached to the main body box 2 or removed from the main body box 2.

A blower unit 10 is installed on each side of the heat exchanger 1 in the main body box 2. One blower unit 10 is a large-sized component that constitutes a fan casing of the exhaust blower 5, a part of the exhaust passage 6, and a part of the air supply passage 4, and the other blower unit 10 is also the air blower 3.
Are large parts that constitute a fan casing, a part of the supply passage 4 and a part of the exhaust passage 6. Each motor 11 of the exhaust blower 5 and the supply blower 3 is fixed by a holding member 12 as a structural component provided on the heat exchanger 1 side. Each holding member 12 is detachably fixed to the main body box 2 without using screws or welding. That is, as shown in FIG. 4, a slit-shaped notch hole 13 is provided on the main body box 2 side along the top plate portion and the bottom plate portion, and two holding members 12 can be fitted and fixed in each notch hole 13. Hook-shaped fitting portions 14 are provided on the upper and lower sides. Then, each holding member 12 is detachably fixed to the main body box 2 by fitting each fitting portion 14 into each notch hole 13. Structural components such as components defining the air supply passage 4 and the exhaust passage 6 are also included in the holding member 12.
In the same manner as described above, the fitting portion 14 and the
Is fixed to the main body box 2 so as to be disassembled.

Further, each blower unit 1 is provided in the main body box 2.
A knock-out structure 15 that can be opened to a size that allows each blower unit 10 to be taken out is provided as shown in FIG. As shown in FIGS. 5 and 6, a heat insulating material 17 is attached to the outer surface of the main body box 2 with a release paper 16 such as synthetic paper (Yupo) interposed between the outer surface and the outer surface. The heat insulating material 17 is attached on the outer surface of the main body box 2 with the release paper 16 attached thereto. However, if the release paper 16 is previously attached to one surface of the heat insulator 17, the heat insulating material 17 is attached. The work becomes easier.

When disposing the heat exchange ventilator having such a configuration, it can be disassembled as follows. Main body box 2
The heat exchanger 1 inserted and attached to the heat exchanger attaching / detaching structure 7 is pulled out, and the heat exchanger 1 is separated from the main body box 2. The heat insulating material 17 covering the outer periphery of the main body box 2 is replaced with a release paper 16.
Then, the entire release paper 16 is peeled off from the outer surface of the main body box 2. The respective knockout structures 15 of the main body box 2 are punched and opened, the holding member 12 is pulled out of the fitting portion 14 from the cutout hole 13, and each blower unit 10 is pulled out of the opening portion. The motor 11 is removed from each holding member 12, and the impeller is further removed from the motor 11. Structural components such as components defining the air supply passage 4 and the exhaust passage 6 are also removed from the main body box 2 and disassembled in the same manner as the holding member 12.
In this way, the disassembly can be performed without the troublesome and difficult operation of removing the screws, and the heat insulating material 17 can be easily peeled off and separated.

Since the reinforcing member, the guide rail and the like are not fixed to the main body box 2 by screwing or welding, it is not necessary to disassemble them. From a manufacturing standpoint, there is little screw tightening, welding or caulking work, so that the assemblability is good and the productivity is improved. In addition, since no reinforcing member or guide rail is required, the number of parts is reduced and the cost is reduced. As for the knockout structure 15, the disassembly work becomes easier when the air passage of the blower unit 10 and the fan casing are set at positions where they can be taken out first.

In this embodiment, the heat exchange ventilator has been described by way of example. However, the present invention can be applied to other electric devices having the same configuration.
Can be applied to the heat insulating structure of the duct.
