FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] An example of a blower according to the present disclosure will be described in detail below with reference to the drawings. Elements common to the various drawings will be designated by the same reference numerals, and redundant explanations will be omitted. Furthermore, the present disclosure is not limited to the embodiment.

[0011] Embodiment 1 FIG. 1 is a diagram showing an installed state of a blower 1 according to a first embodiment of the present disclosure. In the following description, the terms "up" and "down" refer to the up and down directions in FIG. 1, i.e., the up and down vertical direction. The blower 1 is attached to four suspension bolts 10 suspended from a ceiling 11. The blower 1 includes a blower main body 2, a suspension bracket 3, and a mounting member 4. The ceiling 11 from which the blower 1 is suspended may be the upper surface of a room in a building, or the upper surface of an attic space.

[0012] The blower main body 2 has a housing 21. The housing 21 of the first embodiment is a rectangular parallelepiped and has a first side surface 21a, a second side surface 21b, a third side surface 21c, a fourth side surface 21d (not shown), a top plate 21e, and a bottom plate 21f. An air inlet 22 is provided in the first side surface 21a. The second side surface 21b faces the first side surface 21a and has an air outlet 23 provided therein. The third side surface 21c and the fourth side surface 21d are perpendicular to the first side surface 21a and the second side surface 21b, respectively. The third side surface 21c and the fourth side surface 21d face each other. The surface facing the front of the paper in FIG. 1 is the third side surface 21c, and the surface facing the back of the paper is the fourth side surface 21d.

[0013] The air inlet 22 is connected to the inside of the room via a duct (not shown). The air outlet 23 is connected to the outside of the room via a duct (not shown). A blower fan (not shown) is provided inside the housing 21, and when the blower fan is driven, the air inside the room passes through the housing 21 and is discharged to the outside of the room. Note that in this embodiment, an air blower that discharges the air inside the room to the outside will be described as an example, but the air blower may be an air blower that supplies outside air into the room, or a heat exchange type air blower that exchanges heat between the air inside the room and the air outside the room.

[0014] The hanging brackets 3 are fixed to four corners of the housing 21 of the air blower main body 2. The four hanging brackets 3 are referred to as a first hanging bracket 31, a second hanging bracket 32, a third hanging bracket 33 (not shown), and a fourth hanging bracket 34 (not shown). The first hanging bracket 31 is fixed to the first side surface 21a and the third side surface 21c. The second hanging bracket 32 ​​is fixed to the second side surface 21b and the third side surface 21c. The third hanging bracket 33 is fixed to the first side surface 21a and the fourth side surface 21d. The fourth hanging bracket 34 is fixed to the second side surface 21b and the fourth side surface 21d. The specific configuration of the hanging brackets 3 will be described later.

[0015] The mounting members 4 are inserted into four suspension bolts 10 suspended from the ceiling. Nuts 12 are attached to the suspension bolts 10 below the mounting members 4, and the mounting members 4 are supported and positioned by the nuts 12. The hanging fittings 3 fixed to the air blower main body 2 are attached to the mounting members 4, respectively, so that the air blower 1 is suspended from the ceiling 11. Details of the mounting members 4 will be described later.

[0016] Fig. 2 is a diagram showing the first suspending fitting 31 of embodiment 1 as seen from above. Fig. 3 is a diagram showing the first suspending fitting 31 of embodiment 1 as seen from the side of the second side surface 21b of the air blower body 2. In Figs. 2 and 3, the configuration other than the first suspending fitting 31 is omitted.

[0017] First hanging bracket 31 is a metal plate that extends horizontally and includes opening surface 311 with opening 311a for attachment to hanging bolt 10, first fixing surface 312 that extends downward from the end of opening surface 311 on the air inlet 22 side and is fixed to first side surface 21a of air blower body 2, and second fixing surface 313 that extends downward from the end of opening surface 311 on the housing 21 side of air blower body 2 and is fixed to third side surface 21c of air blower body 2. In the first embodiment, opening 311a formed in opening surface 311 is circular. First fixing surface 312 has protrusion 312a for fixing to first side surface 21a of air blower body 2, and protrusion 312a has first screw fixing portion 312b for screw fixing. Second fixing surface 313 is formed with a second screw fixing portion (not shown) for fixing to third side surface 21c of blower body 2 with a screw or the like.

[0018] The second hanging bracket 32 ​​has a structure that is mirror-symmetrical to the first hanging bracket 31. Although the detailed structure of the second hanging bracket 32 ​​is not shown in the drawings, the first fixing surface 312 of the second hanging bracket 32 ​​that corresponds to the first fixing surface 312 of the first hanging bracket 31 is fixed to the second side surface 21b of the air blower body 2, and the second fixing surface 313 of the second hanging bracket 32 ​​that corresponds to the second fixing surface 313 of the first hanging bracket 31 is fixed to the third side surface 21c of the air blower body 2. In addition, the opening surface 311 of the second hanging bracket 32 ​​that corresponds to the opening surface 311 of the first hanging bracket 31 is oriented parallel to the horizontal direction. The third hanging bracket 33 and the fourth hanging bracket 34 have the same shapes as the second hanging bracket 32 ​​and the first hanging bracket 31, respectively.

[0019] Fig. 4 is an enlarged view of the mounting member 4 of the first embodiment, showing the state before the hanging fitting 3 is attached to the mounting member 4. Fig. 5 is an enlarged view of the mounting member 4 of the first embodiment, showing the state after the hanging fitting 3 has been attached to the mounting member 4. In the first embodiment, the four mounting members 4 attached to the four hanging bolts 10 will be described as having the same structure.

[0020] The mounting member 4 has a first member 41, a second member 42 provided below the first member 41, and a third member 43 provided below the second member 42. In the first embodiment, the first member 41, the second member 42, and the third member 43 are integrally formed.

[0021] The first member 41 is a hollow truncated cone, with a cavity formed along its height into which a suspension bolt is inserted. A truncated cone is a solid body formed by cutting a cone along a plane parallel to its base, excluding the small cone portion. The outer diameter of the top surface of the truncated cone of the first member 41 is smaller than the outer diameter of the bottom surface. In other words, the second outer diameter, which is the outer diameter of the bottom surface of the first member 41 in the vertical direction, is larger than the first outer diameter, which is the outer diameter of the top surface of the truncated cone of the first member 41 in the vertical direction. The outer diameter of the top surface of the truncated cone of the first member 41 is smaller than the width of the opening 311a of the suspension fitting 3, i.e., the diameter of the opening 311a. The outer diameter of the bottom surface of the truncated cone of the first member 41 is larger than the width of the opening 311a of the suspension fitting 3. The first member 41 is made of an elastic material such as rubber, and is elastically deformable.

[0022] The second member 42 is a hollow cylinder made of an elastic material, and has a cavity formed along the height direction of the cylinder into which the suspension bolt 10 is inserted. The third outer diameter, which is the outer diameter of the second member 42, is smaller than the outer diameter of the lower surface of the truncated cone of the first member 41, i.e., the second outer diameter on the vertically lower side of the first member 41. The outer diameter of the second member 42 is also the same dimension as the width of the opening 311a of the suspension hardware 3.

[0023] The third member 43 is a hollow cylinder made of an elastic material, and a cavity is formed along the height direction of the cylinder into which the suspension bolt 10 is inserted. The fourth outer diameter, which is the outer diameter of the third member 43, is larger than the third outer diameter, which is the outer diameter of the second member 42. The outer diameter of the third member 43 is also larger than the width of the opening 311a of the suspension hardware 3.

[0024] The operation of hanging the air blower 1 will now be described. The air blower body 2 is lifted, and the four hanging bolts 10 attached to the ceiling are passed through the openings 311a of the four hanging brackets 3 attached to the air blower body 2. With the air blower body 2 lifted, the mounting members 4 are passed through each of the four hanging bolts 10 from below. After that, one washer (not shown) and two nuts 12 are passed through each of the four hanging bolts 10 in order, and the position of the mounting members 4 is fixed using the two nuts 12 at the specified hanging position.

[0025] A load is applied to the first and third hanging fittings 31 and 33 from above the fixed mounting member 4, pushing the two hanging fittings 3 down to the second member 42 of the mounting member 4. At this time, the outer diameter of the underside of the first member 41 is larger than the width of the opening 311a of the hanging fitting 3. However, the first member 41 is elastically deformable, and applying a load to the first member 41 causes it to contract, thereby pushing the hanging fitting 3 down. After the hanging fitting 3 is pushed down to the second member 42, the contraction of the first member 41 is released, and the width of the opening 311a of the hanging fitting 3 becomes smaller than the outer diameter of the underside of the first member 41. This prevents the hanging fitting 3 from moving upward from the second member 42. Furthermore, because the width of the opening 311a of the hanging fitting 3 is smaller than the outer diameter of the third member 43, the hanging fitting 3 is supported by the third member 43. Then, a load is applied to the second hanging bracket 32 ​​and the fourth hanging bracket 34, and the two hanging brackets 3 are similarly pushed down to the second member 42 of the mounting member 4, thereby allowing the blower main body 2 to be mounted horizontally.

[0026] The air blower 1 of the first embodiment includes an air blower main body 2, a hanging bracket 3 fixed to the air blower main body 2 and having an opening 311a for insertion of a hanging bolt 10, and a mounting member 4 attached to the hanging bolt 10 and to which the hanging bracket 3 is attached, the mounting member 4 including: an elastically deformable first member 41 having a second outer diameter at a lower vertical position that is larger than a first outer diameter at an upper vertical position; a second member 42 formed below the first member 41, having a third outer diameter smaller than the second outer diameter, to which the hanging bracket 3 is attached; and a third member 43 formed below the second member 42 and having a fourth outer diameter larger than the third outer diameter. This allows the hanging bracket 3 to be fixed by elastically deforming the first member 41 of the mounting member 4 and pressing the hanging bracket 3 down to the second member 42, thereby enabling the hanging bracket 3 to be fixed without using a nut on the upper part of the hanging bracket 3, thereby reducing the frequency of tool use. Therefore, the workability of the suspension work on the suspension bolt 10 can be improved.

[0027] Furthermore, according to the blower 1 of the first embodiment, the width of the opening 311a of the hanging fitting 3 is larger than the first outer diameter and smaller than the second outer diameter, which prevents the hanging fitting 3 from slipping upward from the second member 42 of the mounting member 4.

[0028] Furthermore, according to the blower 1 of the first embodiment, the second member 42 and the third member 43 are elastically deformable. This allows the mounting member 4 to be integrally formed. Furthermore, by forming the first member 41, the second member 42, and the third member 43 all from elastic materials, the mounting member 4 can function as a vibration-proof device that suppresses vibration of the blower body 2.

[0029] A modification of the first embodiment will be described.

[0030] In the first embodiment, the opening 311a is described as being circular, but it may also be elliptical.

[0031] Furthermore, in the first embodiment, the first member 41, the second member 42, and the third member 43 are described as being integrally formed, but they may also be separate members.

[0032] In addition, in the first embodiment, the first member 41 has been described as being a truncated cone, but the first member 41 may be a truncated pyramid instead of a truncated cone. Furthermore, the second member 42 and the third member 43 are not limited to being cylindrical, and may be rectangular prisms such as octagonal prisms.

[0033] Furthermore, in the first embodiment, the outer diameter of the second member 42 is described as being the same as the width of the opening 311a of the hanging fitting 3, but this does not have to be the case. For example, the outer diameter of the second member 42 may be smaller than the width of the opening 311a of the hanging fitting 3, or may be larger than the width of the opening 311a of the hanging fitting 3 if the second member 42 is an elastic body.

[0034] Furthermore, in the first embodiment, the four mounting members 4 are described as having the same structure, but they may have different shapes.

[0035] Furthermore, the structure of the hanging fitting 3 is not limited to the configuration described in embodiment 1. For example, although embodiment 1 describes the hanging fitting 3 as being fixed to two side surfaces of the housing 21 of the blower main body 2, it may be fixed to only one surface.

[0036] Embodiment 2 The blower 1 of the second embodiment will be described with reference to Figs. 6 to 8. Fig. 6 is a diagram showing the hanging fitting 3 in the second embodiment, as viewed from above. Fig. 7 is an enlarged view of the mounting member 4 of the second embodiment, showing the state before the hanging fitting 3 is attached to the mounting member 4. Fig. 8 is an enlarged view of the mounting member 4 of the second embodiment, showing the state after the hanging fitting 3 is attached to the mounting member 4.

[0037] Air blower 1 of embodiment 2 differs from air blower 1 of embodiment 1 in the shape of opening surface 311 of hanging bracket 3. In embodiment 1, hanging bracket 3 has circular opening 311a, but in embodiment 2, opening 311a is a U-shaped notch. U-shaped opening 311a has curved portion 311a1 and straight portion 311a2 extending from curved portion 311a1. Hanging bracket 3 is attached to air blower body 2 so that the straight line connecting air inlet 22 and air outlet 23 provided in air blower body 2 is parallel to straight portion 311a2 of U-shaped opening 311a, and so that curved portion 311a1 of U-shaped opening 311a protrudes outward from air blower body 2.

[0038] The relationship between the size of the opening 311a of the hanging fitting 3 and the mounting member 4 in the second embodiment will be described. As in the first embodiment, the first member 41 is a hollow truncated cone, with a cavity formed along the height of the truncated cone. As in the first embodiment, the outer diameter of the top surface of the truncated cone of the first member 41 is smaller than the outer diameter of the bottom surface of the truncated cone. That is, the second outer diameter, which is the outer diameter of the bottom surface of the first member 41 in the vertical direction, is larger than the first outer diameter, which is the outer diameter of the top surface of the truncated cone in the vertical direction. Furthermore, the outer diameter of the top surface of the truncated cone is smaller than the width of the opening 311a of the hanging fitting 3, and the outer diameter of the bottom surface of the truncated cone is larger than the width of the opening 311a of the hanging fitting 3. Note that the width of the opening 311a of the hanging fitting 3 is the distance between the two straight portions 311a2 of the opening 311a. As in the first embodiment, the first member 41 is made of an elastic material such as rubber and is elastically deformable.

[0039] As in the first embodiment, the second member 42 is a hollow cylinder with a cavity formed along the height direction of the cylinder. The third outer diameter, which is the outer diameter of the second member 42, is smaller than the outer diameter of the lower surface of the truncated cone of the first member 41, i.e., the second outer diameter on the vertically lower side of the first member 41. The outer diameter of the second member 42 is the same dimension as the width of the opening 311a of the hanging fitting 3. Note that the outer diameter of the second member 42 may be smaller or larger than the width of the opening 311a of the hanging fitting 3.

[0040] As in the first embodiment, the third member 43 is a hollow cylinder with a cavity formed along the height direction of the cylinder. The fourth outer diameter of the third member 43 is larger than the third outer diameter of the second member 42. The outer diameter of the third member 43 is also larger than the width of the opening 311a of the hanging hardware 3.

[0041] The procedure for hanging the air blower 1 will now be described. A mounting member 4 is passed through each of the four hanging bolts 10 attached to the ceiling from below. Then, one washer (not shown) and two nuts 12 are passed through each of the four hanging bolts 10, in order, and the two nuts 12 are used to secure the mounting member 4 in place at the desired hanging position. The U-shaped openings 311a of the four hanging brackets 3 attached to the air blower main body 2 are passed through the hanging bolts 10, respectively, and the four hanging brackets 3 are placed on top of the mounting members 4. A load is then applied to the first hanging bracket 31 and the third hanging bracket 33, and the two hanging brackets 3 are lowered to the second member 42 of the mounting member 4. Next, a load is applied to the second hanging bracket 32 ​​and the fourth hanging bracket 34, and the two hanging brackets 3 are similarly lowered to the second member 42 of the mounting member 4, thereby horizontally mounting the air blower main body 2.

[0042] According to the air blower 1 of the second embodiment, the opening 311a of the hanging bracket 3 is a U-shaped notch. This eliminates the need to attach the mounting member 4 to the hanging bolt 10 while the air blower body 2 is lifted, thereby reducing the burden on the worker compared to the first embodiment.

[0043] Embodiment 3 The blower 1 of the third embodiment will be described with reference to Figs. 9 to 12. Fig. 9 is a diagram showing the hanging fitting 3 in the third embodiment, as seen from above. Fig. 10 is a diagram showing the hanging fitting 3 in the third embodiment, as seen from the side of the second side surface 21b of the blower body 2. Fig. 11 is an enlarged view of the mounting member 4 in the third embodiment, showing the state before the hanging fitting 3 is attached to the mounting member 4. Fig. 12 is an enlarged view of the mounting member 4 in the third embodiment, showing the state after the hanging fitting 3 is attached to the mounting member 4.

[0044] The blower 1 of embodiment 3 differs from the blower 1 of embodiment 2 in the shape of the hanging fitting 3 and the shape of the third member 43. In embodiment 3, two cylindrical hanging fitting protrusions 311b are provided on the underside of the hanging fitting 3. The two hanging fitting protrusions 311b are arranged on the opening surface 311 so as to sandwich the opening 311a therebetween.

[0045] In the third embodiment, the third member 43 has two third member recesses 43a, which are cylindrical recesses, on the upper surface of a cylindrical body. The two third member recesses 43a are formed on the upper surface of the third member 43 at positions corresponding to the two hanging hardware protrusions 311b, respectively. The hanging hardware protrusions 311b can be fitted into the third member recesses 43a. In other words, the hanging hardware protrusions 311b and the third member recesses 43a form a fixing member for fixing the hanging hardware 3 and the mounting member 4 together.

[0046] The work of hanging the air blower 1 will now be described. Similar to the procedure in the second embodiment, the mounting members 4, washers, and nuts 12 are attached to the hanging bolts 10, and the hanging bolts 10 are passed through the U-shaped openings 311a of the four hanging brackets 3, placed on top of the respective mounting members 4, and pushed down to the second member 42. Thereafter, the hanging brackets 3 are fixed in place by fitting the hanging bracket convex portions 311b into the third member concave portions 43a.

[0047] According to the blower 1 of the third embodiment, the opening 311a of the hanging bracket 3 is a notch, and is provided with fixing members (hanging bracket convex portion 311b and third member concave portion 43a) that fix the hanging bracket 3 to the mounting member 4. As a result, the hanging bracket convex portion 311b fits into the third member concave portion 43a, and in addition to the effect achieved in the second embodiment, the stability of the ceiling-suspended structure of the blower 1 can be improved.

[0048] In the third embodiment, an example has been described in which two hanging hardware convex portions 311b and two third member concave portions 43a are provided, but one of each may be provided, or three or more of each may be provided.

[0049] Embodiment 4 The blower 1 of the fourth embodiment will be described with reference to Figs. 13 to 15. Fig. 13 is a diagram showing the hanging fitting 3 in the fourth embodiment, as viewed from above. Fig. 14 is an enlarged view of the mounting member 4 of the fourth embodiment, showing the state before the hanging fitting 3 is attached to the mounting member 4. Fig. 15 is an enlarged view of the mounting member 4 of the fourth embodiment, showing the state after the hanging fitting 3 is attached to the mounting member 4.

[0050] The blower 1 of embodiment 4 differs from the blower 1 of embodiment 2 in the shape of the hanging fitting 3 and the shape of the third member 43. In embodiment 4, the hanging fitting 3 has two cavities 311c in the opening surface 311. The two cavities 311c are arranged on either side of the opening 311a in the opening surface 311.

[0051] Furthermore, in the fourth embodiment, the third member 43 has two third member protrusions 43b. The two third member protrusions 43b are formed on the top surface of the third member 43 at positions corresponding to the two hollow portions 311c. The third member protrusions 43b can be fitted into the hollow portions 311c of the hanging hardware 3. In other words, the third member protrusions 43b and the hollow portions 311c form a fixing member for fixing the hanging hardware 3 and the mounting member 4 together.

[0052] The work of hanging the blower 1 will now be described. Similar to the procedure in the second embodiment, the mounting members 4, washers, and nuts 12 are attached to the hanging bolts 10, and the hanging bolts 10 are passed through the U-shaped openings 311a of the four hanging brackets 3, placed on top of the mounting members 4, and pushed down to the second member 42. Thereafter, the third member protrusions 43b of the third member 43 are fitted into the hollow portions 311c of the hanging brackets 3, thereby fixing the hanging brackets 3 in place.

[0053] According to the blower 1 of the fourth embodiment, the opening 311a of the hanging bracket 3 is a notch, and is provided with fixing members (corresponding to the hollow portion 311c and the third member protrusion 43b) that fix the hanging bracket 3 to the mounting member 4. As a result, the third member protrusion 43b fits into the hollow portion 311c, and in addition to the effect achieved in the second embodiment, the stability of the ceiling-suspended structure of the blower 1 can be improved.
