The heat exchange element 86 is provided inside the main body 81 at a position where the exhaust airflow A91 and the intake airflow A93 intersect, and exchanges heat between these airflows.

[0017] The mounting structure 100 will be described with reference to Figs. 3 and 4. Fig. 3 is a side view of the mounting structure 100. Fig. 4 is an enlarged side cross-sectional view of the area surrounded by a circle E in Fig. 3. The mounting structure 100 is a structure for mounting the ventilation device 80 to the rafter 72 using the device mounting part 14. The ventilation device 80 is installed between two rafters 72 extending in parallel. The device mounting part 14 in this example is a member extending along the extension direction of the rafter 72, and has a base part 11, a rafter mounting part 12, a device mounting part 14, and a panel frame mounting part 16. Hereinafter, the horizontal direction parallel to the extension direction of the rafter 72 is referred to as the "vertical direction", and the horizontal direction perpendicular to the vertical direction is referred to as the "side", "horizontal direction" or "horizontal".

[0018] The base portion 11 is a flat portion extending vertically along the siding 72. The siding mounting portion 12 is provided in the base portion 11 at approximately the center in the width direction in order to fix the base portion 11. The siding mounting portion 12 has a plurality of mounting holes 122 arranged vertically. The base portion 11 is fixed to the siding 72 by screwing wood screws B2 into the siding 72 through the mounting holes 122.

[0019] The device mounting portion 14 is provided on the base portion 11 at a position closer to the ventilation device 80 in the width direction in order to fix the base portion 11 to the ventilation device 80. The device mounting portion 14 has a first portion 141 extending laterally and a second portion 142 extending upward from an end of the first portion 141, and has an angled cross section in a side view. The first portion 141 has a plurality of mounting taps 143 arranged in the vertical direction. The mounting taps 143 in this example are burring taps. The second portion 142 has a plurality of mounting holes 144 arranged in the vertical direction.

[0020] An angle member 84, which has an angle-shaped cross section in a side view and extends vertically, is fixed to a side surface of a main body 81 of the ventilation device 80. The angle member 84 has a flange portion 841 extending laterally from the side surface of the main body 81, and a flange support portion 842 extending upward from the end of the flange portion 841 along the side surface of the main body 81 and fixed to the main body 81. The flange portion 841 has a plurality of mounting holes 846 arranged vertically. The plurality of mounting holes 846 are provided at positions corresponding to the plurality of mounting taps 143.

[0021] The first portion 141 of the device mounting portion 14 contacts the flange portion 841, and the second portion 142 contacts the flange support portion 842. In this state, the bolt B3 is screwed into the mounting tap 143 through the mounting hole 846, whereby the device mounting portion 14 is fixed to the main body 81 via the angle member 84. The second portion 142 and the flange support portion 842 may be fastened together to the side surface of the main body 81 by the bolt B4.

[0022] The panel frame mounting portion 16 is provided on the base portion 11 at a position away from the ventilation device 80 in the width direction in order to fix the panel frame 62 of the cover panel 60. The panel frame mounting portion 16 has a plurality of mounting taps 162 arranged in the vertical direction. The mounting taps 162 in this example are burring taps.

[0023] As shown in FIG. 4, the device mounting portion 14 is provided closer to the ventilation device 80 than the furring strip mounting portion 12 , and the panel frame mounting portion 16 is provided farther from the ventilation device 80 than the furring strip mounting portion 12 .

[0024] The cover panel 60 is provided below the ventilation device 80, and is a substantially rectangular member that covers an opening 702 formed in the ceiling material 70 for mounting the ventilation device 80. The cover panel 60 is provided with a window (not shown) for exposing the louver 87.

[0025] The panel frame 62 is a frame member having a connecting portion 622, a downward extending portion 624, and a side extending portion 626, each of which extends in the vertical direction. The connecting portion 622 is a portion that extends laterally, and is connected to the base portion 11. The downward extending portion 624 is a portion that extends downward from the end of the connecting portion 622. The side extending portion 626 is a portion that extends laterally from the lower end of the downward extending portion 624, and is in contact with the ceiling material 70.

[0026] A pair of panel frames 62 are provided on both the left and right sides of the ventilation device 80. The pair of panel frames 62 are connected by a plurality of (e.g., three) horizontal frame members 64 arranged vertically apart. The horizontal frame members 64 are frame members extending horizontally. The horizontal frame members 64 are connected to the panel frame 62 by bolts B5. The panel frame 62 has a plurality of mounting taps 627 arranged vertically. In this example, the mounting taps 627 are burring taps. The cover panel 60 is fixed to the panel frame 62 by the bolts B5 penetrating the cover panel 60 and screwing into the mounting taps 627. In addition to the panel frame 62, the horizontal frame members 64 may also be provided with mounting taps for mounting the cover panel 60.

[0027] The connecting portion 622 has a plurality of mounting holes 623 that are arranged vertically and penetrate vertically. The plurality of mounting holes 623 are provided at positions corresponding to the plurality of mounting taps 162. The panel frame 62 is fixed to the panel frame mounting portion 16 of the ventilator mounting member 10 by screwing the bolts B1 into the mounting taps 162 through the mounting holes 623.

[0028] The ceiling material 70 has a wide variety of thicknesses. In this example, as shown in Fig. 4, the connecting portion 622 is fixed at a position spaced apart from the panel frame mounting portion 16 by a gap G1. Therefore, in this embodiment, by providing the gap G1 between the connecting portion 622 and the panel frame mounting portion 16, the difference in thickness of the ceiling material 70 can be easily accommodated.

[0029] A side surface of the main body 81 of the ventilation device 80 is provided with an overhanging portion 88 that overhangs laterally from the side surface of the main body 81 through the upper side of the joist 72, in addition to the angle member 84. The overhanging portion 88 in this example has a lateral overhanging portion 881 that extends laterally from the side surface of the main body 81, a downward overhanging portion 882 that extends downward from the end of the lateral overhanging portion 881, and a connecting portion 883 that extends laterally from the end of the downward overhanging portion 882. The connecting portion 883 is provided with a mounting tap 884 at a position corresponding to the mounting tap 162. The lateral overhanging portion 881 of the overhanging portion 88 contacts the upper side of the joist 72.

[0030] The tip side of bolt B1 is screwed into a mounting tap 884 of a connection portion 883 of the overhanging portion 88. With this configuration, the panel frame mounting portion 16 is fixed to the main body 81 via the overhanging portion 88. Since the base portion 11 and the overhanging portion 88 are connected to each other with the joist 72 sandwiched between them, the main body 81 of the ventilation device 80 is firmly fixed to the joist 72.

[0031] The siding 72 has various variations in thickness. In this example, as shown in Fig. 4, the connection part 883 is fixed at a position spaced apart from the panel frame mounting part 16 of the base part 11 by a gap G2. Therefore, in this embodiment, by having the gap G2 between the connection part 883 and the panel frame mounting part 16, the difference in thickness of the siding 72 can be easily absorbed.

[0032] As described above, since there are various variations in the lateral spacing of the rafters 72, there are also various variations in the spacing between the main body 81 and the rafters 72. In this example, as shown in Fig. 4, the downward projection 882 is spaced apart from the rafters 72 by a gap G3, and the flange support 842 is spaced apart from the rafters 72 by a gap G4. For this reason, this embodiment can easily absorb the difference in spacing between the main body 81 and the rafters 72 by having the gaps G3 and G4.

[0033] Next, an example of a method for mounting the ventilation device 80 will be described. (1) Place the extension portion 88 on the siding 72 and position the ventilation device 80 between the sidings 72. (2) Fix the ventilator mounting member 10 to the ventilator 80 using bolts B3 and B4. (3) Use wood screws B2 to secure the ventilation device mounting member 10 to the rafters 72. (4) Using the bolts B1, fix the panel frame 62 to the ventilation device mounting member 10. At this time, the tip of the bolt B1 is first screwed into the mounting tap 162, and then screwed into the mounting tap 884. In this state, the panel frame 62 is connected to the panel frame mounting portion 16, and the base portion 11 and the overhanging portion 88 are connected. (5) Fix the cover panel 60 to the panel frame 62 using bolts B5.

[0034] This mounting method is merely one example, and various modifications are possible.

[0035] Next, the characteristics of the ventilator mounting member 10 of the embodiment will be described. The ventilator mounting member 10 includes a base portion 11 having a sill mounting portion 12 and a device mounting portion 14, so that the ventilator 80 can be easily mounted to the sill 72. By providing a plurality of mounting holes 122 at different positions in the lateral direction as the sill mounting portion 12, it is possible to accommodate existing sills 72 that are provided at various intervals. As a result, it is easy to replace an existing ventilation device and a newly installed ventilation device that are mounted in different positions.

[0036] Furthermore, since the ventilator mounting member 10 has the panel frame mounting portion 16 for fixing the panel frame 62, a separate member for fixing the panel frame 62 can be omitted.

[0037] Furthermore, since the panel frame 62 and the protruding portion 88 can be connected to the panel frame mounting portion 16 by the bolt B1, a separate bolt and the man-hours required for screwing in the separate bolt can be eliminated.

[0038] In addition, since the panel frame mounting portion 16 is provided farther from the ventilation device 80 than the joist mounting portion 12, the distance between the pair of left and right panel frames 62 can be increased to mount a cover panel 60 with a larger width. As a result, the cover panel 60 can cover a wide area where the ventilation device 80 has been replaced, improving the aesthetic appearance after construction.

[0039] Furthermore, according to the method of mounting the ventilation device 80 using the ventilation device mounting member 10, it is possible to accommodate existing sills 72 of various intervals, thereby reducing ancillary work such as carpentry work for the sills and replacing the ceiling wallpaper.
