[0027]
Next, a structure for installing the bathroom heating / drying machine 21 above the ceiling will be described. FIG. 5 is a front view showing the structure of a hanging support 37 attached to the hanging bolt 29 and supporting the bathroom heating / drying body 22, and FIG. 6 is a sectional view taken along line XX of FIG. . FIG. 7 is an exploded perspective view of the hanging support 37. As shown in FIG. 7, the suspension support 37 includes an upper nut 43, a temporary holding spring member 44, an upper elastic member 45, a lower elastic member 46, and a lower nut 47.
[0028]
The temporary holding spring member 44 is formed by bending a sheet metal, and as shown in FIG. 7, through holes 48 through which the suspension bolts 29 can be inserted are formed from both ends of a horizontal piece 49 opened at the center. The elastic piece 50 hangs down, the support piece 51 extends horizontally outward from the lower end of the elastic piece 50, and the guide piece 52 extends obliquely downward from the tip of the support piece 51 inward. As shown in FIG. 6, the width of the temporary holding spring member 44 is slightly smaller than the width of the mounting hole 30 opened in the casing 24, and the length of the horizontal piece 49 is also larger than the length of the mounting hole 30. The length of the temporary holding spring member 44 is longer than the length of the mounting hole 30.
[0029]
As shown in FIGS. 5 and 6, the upper nut 43 is screwed to the suspension bolt 29, and the temporary holding spring member 44 with the suspension bolt 29 inserted through the through hole 48 is held by the upper nut 43. Have been. That is, the upper nut 43 is integrated with the temporary holding spring member 44 so that the temporary holding spring member 44 can be held when the upper nut 43 is attached to the suspension bolt 29. For example, the upper nut 43 may be joined to the upper surface of the horizontal piece 49 of the temporary holding spring member 44 by welding or the like, and a projection provided on the lower surface of the upper nut 43 in the through hole 48 of the horizontal piece 49 may be rotated. It may be connected freely. In the construction state, the temporary holding spring member 44 is inserted into the mounting hole 30 from the upper surface side of the mounting location of the casing 24, the elastic piece 50 and the support piece 51 pass through the mounting hole 30, and the support piece 51 Is facing the lower surface of the casing 24.
[0030]
The upper elastic member 45 is made of a material having elasticity such as rubber or plastic, and a shaft portion 54 is vertically suspended from a lower surface of a horizontally long rectangular elastic pressing portion 53 having a width larger than the width of the mounting hole 30. A through hole 55 is provided from the elastic holding portion 53 to the shaft portion 54. While the upper elastic member 45 has elasticity, it has rigidity enough to press the upper surface of the mounting portion of the casing 24. For example, a metal core may be inserted into the elastic holding portion 53 made of rubber or soft plastic, or a hard plastic having appropriate elasticity, such as polyethylene, having a certain thickness may be used. The elastic member 45 may be formed in advance. The upper elastic member 45 has the upper surface of the elastic pressing portion 53 adhered to the lower surface of the horizontal piece 49 of the temporary holding spring member 44 with an adhesive or a double-sided adhesive tape. In the construction state, the suspension bolt 29 is inserted into the through hole 55 of the upper elastic member 45, and the lower surfaces of both sides of the elastic pressing portion 53 are in contact with the upper surface of the casing 24.
[0031]
The lower elastic member 46 is formed of a material having elasticity such as rubber or plastic into a cylindrical shape having a larger diameter than the mounting hole 30, and the shaft portion 54 of the upper elastic member 45 fits almost exactly on the upper surface. The fitting hole 56 penetrates. The lower elastic member 46 is inserted with the suspension bolt 29 on the lower surface side of the casing 24, and tightens the lower nut 47 screwed to the suspension bolt 29 on the lower surface side of the lower elastic member 46 so that the elasticity of the upper elastic member 45 is reduced. The edge of the mounting hole 30 (that is, the location where the casing 24 is attached) is sandwiched between the holding portion 53 and the upper surface of the lower elastic member 46.
[0032]
As a result, the bathroom heater / dryer main body 22 is supported by the suspension support 37 so as to be suspended by a plurality of, for example, four or three suspension bolts 29 inserted through the mounting holes 30. Further, since the bathroom heating / drying device main body 22 is supported so as to be sandwiched between the upper elastic member 45 and the lower elastic member 46, the vibration of the motor and the like inside the bathroom heating / drying device main body 22 is also reduced. And the lower elastic member 46 can absorb the vibration noise.
[0033]
Next, the procedure for installing the bathroom heating / drying machine 21 above the ceiling will be described with reference to FIGS. 8 and 9. First, as shown in FIG. 8A, an upper nut 43, a temporary holding spring member 44, and an upper elastic member 45 are attached to each suspension bolt 29. The upper nut 43 and the temporary holding spring member 44 are integrated, and the upper elastic member 45 is adhered to the lower surface of the temporary holding spring member 44. Thus, the upper nut 43, the temporary holding spring member 44, and the upper elastic member 45 can be attached to the suspension bolt 29. After attaching these to the suspension bolts 29, the upper nut 43 is turned so that the temporary holding spring members 44 and the upper elastic members 45 attached to the respective suspension bolts 29 have substantially the same height from the ceiling panel 38. Adjust so that
[0034]
Next, the bathroom heater / dryer body 22 is delivered into the opening 39 of the ceiling panel 38 and lifted to the ceiling. At this time, each hanging bolt 29 is positioned within the hanging bolt recess 28 of the casing 24, and the lower end of the hanging bolt 29 is inserted into the mounting hole 30 opened on the bottom surface of the hanging bolt recess 28. When each hanging bolt 29 enters the mounting hole 30, the bathroom heating / drying body 22 is lifted, and the bathroom heating / drying body 22 is pushed upward as it is.
[0035]
When the bathroom heater / dryer body 22 is pushed upward, the edge of the mounting hole 30 of the casing 24 comes into contact with the guide piece 52 of the temporary holding spring member 44 as shown in FIG. Further, when the bathroom heater / dryer main body 22 is pushed up, the guide piece 52 is pushed inward by the edge of the mounting hole 30, so that the elastic piece 50 is elastically bent inward as shown in FIG. As a result, the support piece 51 and the guide piece 52 are retracted inward, and the edge of the mounting hole 30 moves upward beyond the tip of the support piece 51.
[0036]
When the edge of the mounting hole 30 exceeds the support piece 51, the support piece 51 and the guide piece 52 return to their original positions due to the elastic return force of the elastic piece 50. Accordingly, when the hand supporting the bathroom heating / drying device main body 22 is released, the mounting portion of the casing 24 rides on the support piece 51 and is temporarily held, as shown in FIG. 9D. Therefore, the worker is released from the work of supporting the bathroom heating / drying body 22 at this time.
[0037]
Next, as shown in FIG. 9E, a lower elastic member 46 and a lower nut 47 are attached to each suspension bolt 29, and the lower nut 47 is rotated and tightened. At this time, the shaft portion 54 of the upper elastic member 45 fits into the fitting hole 56 of the lower elastic member 46, and the axes of the upper elastic member 45 and the lower elastic member 46 are aligned. When the lower nut 47 is strongly tightened, the lower surface of the mounting portion of the casing 24 is pushed up by the lower elastic member 46, and as shown in FIG. 46 is strongly sandwiched and supported. In the state where the construction is completed in this way, as shown in FIG. 9 (f), the casing 24 may be lifted from the support piece 51 of the temporary holding spring member 44, or may be on the support piece 51. No problem. Thereafter, the front cover 23 is attached to the lower surface of the bathroom heating / drying body 22.
[0038]
If the temporary holding spring member 44 is not used, the bathroom heater / dryer main body 22 cannot be temporarily held, so the lower elastic member 46 and the lower nut 47 are attached to each hanging bolt 29 as shown in FIG. Even while the lower nut 47 is tightened, the bathroom heater / dryer main body 22 needs to be supported by hand, and work cannot be performed without at least two or more people. On the other hand, according to the construction method of such an embodiment, the lower elastic member 46 and the lower nut 47 can be attached while the bathroom heating / drying body 22 is temporarily held by the temporary holding spring member 44. Therefore, labor can be saved, and the bathroom heater / dryer 21 can be installed alone.
[0039]
If only the bathroom heating / drying body 22 is supported by the temporary holding spring member 44, the bathroom heating / drying body 22 rises up from the temporary holding spring member 44. Further, even when the bottom surface of the recess 28 for the suspension bolt of the casing 24 is pressed by the elastic pressing portion 53, in order to easily fit the edge of the mounting hole 30 between the elastic pressing portion 53 and the support piece 51, The distance between the lower surface of the elastic pressing portion 53 and the upper surface of the support piece 51 needs to be larger than the thickness of the edge of the mounting hole 30 of the casing 24 so that a margin is provided. A gap is formed between the upper surface of the elastic pressing portion 53 and the lower surface of the elastic pressing portion 53. As a result, the bathroom heater / dryer main body 22 may rise or swing due to an earthquake, vibration during running of a large vehicle, or the like. Therefore, in the present invention, in the final construction state, the casing 24 is fastened and fixed with the upper nut 43 and the upper elastic member 45 and the lower elastic member 46 and the lower nut 47, and the bathroom heating / drying body 22 swings. And does not float. Therefore, the bathroom heater / dryer main body 22 is securely fixed, and there is no possibility that vibration noise, chatter noise, or the like is generated. Further, since the casing 24 is sandwiched between the upper elastic member 45 and the lower elastic member 46, the vibration can be absorbed by the elastic members 45 and 46. In particular, if the casing 24 floats from the support piece 51, there is no possibility that vibration noise or the like is generated between the bathroom heating / drying body 22 and the temporary holding spring member 44.
[0040]
Furthermore, the casing 24 is provided with a hanging bolt recess 28 so that the hanging bolt recess 28 can be passed only through the mounting hole 30 opened on the bottom surface of the hanging bolt recess 28. Can be easily passed through the casing 24 of the bathroom heating / drying device main body 22, and the construction can be further simplified.
[0041]
In the above embodiment, the temporary holding spring member 44 is located below the upper nut 43, but the upper nut 43 may be integrated with the lower surface of the horizontal piece 49 of the temporary holding spring member 44. If the horizontal piece 49 of the temporary holding spring member 44 is sandwiched between the two upper nuts 43, the temporary holding spring member 44 and the upper nut 43 may be formed separately.
[0042]
(Second embodiment)
FIG. 10 is an exploded perspective view showing a structure of a hanging support 37 used in another embodiment of the present invention. In the temporary holding spring member 44 used in this embodiment, the width of the elastic piece 50, the support piece 51, and the guide piece 52 is smaller than the width of the mounting hole 30, but from the side edges of the horizontal piece 49. The overhang portion 49a extends horizontally, and the entire width of the horizontal piece 49 is larger than the width of the mounting hole 30. The lower elastic member 46 has a through hole 58 through which the suspension bolt 29 is inserted.
[0043]
Therefore, in the temporary holding spring member 44, the casing 24 is grasped by sandwiching the casing 24 between the overhang portion 49 a and the lower elastic member 46, and the bathroom heating / drying machine main body 22 is supported by the hanging bolts 29. it can. When the temporary holding spring member 44 is made of metal, an elastic sheet 57 made of rubber, soft plastic, foamed plastic or the like may be attached to the lower surface of the horizontal piece 49.
[0044]
According to such an embodiment, since the upper elastic member 45 can be omitted, the number of parts can be reduced, the cost is advantageous, and the construction is simplified.
[0045]

Therefore, the subsequent process of attaching the lower fastener to the hanging bolt and tightening the lower fastener to the mounting location of the air conditioner to support the air conditioner can be easily performed, thereby saving labor. Alternatively, labor saving can be achieved. In a typical case, the work of installing the air conditioner above the ceiling can be performed by one person. Moreover, in the final form, the mounting location of the air conditioner is sandwiched between the upper fastener and the lower fastener, so that the air conditioner is firmly fixed to the suspension bolt.
[0046]
Further, according to the embodiment of the present invention, since the elastic member forming a part of the upper tightening tool is in contact with the upper surface of the mounting location of the air conditioner, vibration of the air conditioner is reduced. It can be absorbed by the elastic member, the upper tightening tool can have a vibration damping action, and it is possible to prevent generation of vibration noise and chatter noise.
[0047]
