On the upper surface of the four frames of the ceiling suspension frame 8, two stays 15, 15 having hooking grooves 16 are erected, respectively. It can be seen from the perspective view of FIG. 3 that the horizontally long mounting hole 17 is formed. Desirably, the ceiling suspension frame 8 has a structure in which two L-shaped components are inserted into a frame shape, and the connecting portions are fastened with setscrews 27 and 27 so that it can be divided into two parts. is there. Reference numeral 28 denotes a terminal table.

As can be seen from FIG. 4A, which is a front perspective view, and FIG. 4B, which is a rear perspective view, the duct joint 18 has a duct connecting short pipe 20 attached to a mounting plate 19 having a through hole 21 formed therein. The duct connecting short pipe 20 and the through hole 21 are made to communicate with each other. In contrast to the duct joint 18, the blind plate 18 a shown in FIG. 1A is configured by only the mounting plate 19 without the duct connecting short pipe 20 and having no through holes 21. In either case, side guide pieces 22 and 22 and side hook-shaped locking pieces 23 are bent at both sides of the mounting plate 19, and a lower hook-shaped locking piece (locking piece) 24 is formed at the center of the lower side. Is bent. The inner dimension between the left and right side guide pieces 22 and 22 is substantially equal to the outer dimension of the stays 15 and 15 described above. As shown in FIG. 5 (A), the duct joint 18 is inclined obliquely from the inside of the ceiling suspension frame 8, and the lower hook-shaped locking piece 24 is first suspended from the ceiling as shown in FIGS. 1 (A) and 1 (B). When it is raised straight as shown in FIG. 5B after being inserted into the horizontally long mounting hole 17 of the frame 8, the side hook-shaped locking piece 23 of the mounting plate 19 is engaged and locked with the hooking groove 16 of the stay 15. Thus, the assembly of the duct joint 18 (or the blind plate 18a) to the ceiling suspension frame 8 is completed with one touch. A sealing material 25 is attached to the back surfaces of the duct joint 18 and the blind plate 18a, and the metal cover 26 of the main body 11 is disposed in close contact with the sealing material 25. Communication between the duct and the inside of the main body 11 is made through the metal cover 26.

Connection cords from remote controllers installed outside the bathroom, and when electric shutters are installed in duct joints, power supply and signal leads from the respective duct joints, as well as toilets and toilets in the case of multi-room ventilation Various wirings such as connection cords from the wall switch may be before or after the main body 11 is attached. However, as shown in FIG. 7, the wires are bundled into a single relay cable 35 and a relay connector 36 is attached to the end thereof. deep. Various lead wires coming out from the electrical parts of the main body 11 to be connected to the various connection cords are also gathered in a single cable 37, and a relay connector 38 is attached to the tip thereof. The relay cables 35 and 37 to which these two relay connectors 36 and 38 are attached are fixed at appropriate positions by a fixture 39 using, for example, the terminal block table 28 of the ceiling suspension frame 8, if necessary. For example, the planar shape formed at one corner of the metal cover 26 and the main body 11 is appropriately hung down from the triangular penetration portion 40. After joining both the relay connectors 36 and 38, together with the hanging relay cables 35 and 37, they are pushed onto the bottom cover of the main body 11 from the penetration point 40, and the bottom lid part of the penetration point 40 is a lid (not shown). You should close it with

In order to assemble a ventilation device using the above devices, exhaust ducts leading to the outside, auxiliary suction ducts from the toilet and washroom are piped to the vicinity of the planned installation position of the main body, and the four anchor bolts 2 and the ceiling Hanging the ceiling suspension frame 8 using the hanging bracket 3 is the same as in the past. The suspension work of the ceiling suspension frame 8 can be performed at any time from the opening 10 and the inspection port (not shown) of the unit bus, so that the unit bus can be carried in at any time. If the size of the ceiling suspension frame 8 is larger than the size of the opening 10 and cannot pass through the cage, remove the set screws 27 , 27 of the ceiling suspension frame 8 and divide them into two parts. Assemble the frame again on the ceiling. Of the four surfaces of the ceiling suspension frame 8 on which the stay 15 is erected, the exhaust joint and the auxiliary suction duct joint 18 are mounted on the maximum three surfaces, and the blind plate 18a is mounted on the remaining surface. Can be done with one touch as described above. Each duct connecting short pipe 20 is inserted with the end of the duct coming to the immediate side, and then tightly coupled by winding a tape, and the ceiling suspension frame 8 is aligned after the unit bus is carried in. That is the same as before. When the metal cover 26 and the main body 11 are pushed from the opening 10 and the main body 11 is screwed, the main body 11 can be temporarily suspended by the annular hanging strap 31, so that the screwing operation can be performed with both hands. it can. Each duct communicates with the inside of the main body 11 through the metal cover 26, but wind leakage can be prevented by the sealing material 25 adhered to the back surfaces of the duct joint 18 and the blind plate 18a.
