According to the method of attaching the range hood disclosed in Patent Document 1, the range hood can be attached to the wall surface with sufficient strength even when the mounting screw is misaligned with the base material inside the wall or in the case of reforming.
However, with such a mounting method, the length of the protruding portion of the mounting screw protruding from the mounting device is short, and it is difficult to hook the wall mounting hole of the range hood onto the protruding portion of the mounting screw, so that it is difficult to mount the range hood.
To solve this problem, shorten the screwing length of the mounting screw into the screw hole of the mounting device, or use a mounting screw with a long overall length, so that the length of the protruding portion of the mounting screw protruding from the mounting device is increased. It is possible to increase the length.
However, if the screwing length of the mounting screw into the screw hole of the mounting device is shortened, the temporary mounting strength of the mounting screw to the mounting device is weak, so the range hood when the wall mounting hole is hooked on the protruding part of the mounting screw The temporary mounting support of the becomes unstable and the range hood may fall.

Also, because the depth of the mounting device (the size between the surface that contacts the wall surface and the surface that contacts the range hood), that is, the length of the screw hole into which the mounting screw is screwed, is limited, use a mounting screw with a long overall length. Then, when the mounting screw is tightened, the tip of the mounting screw comes into contact with the wall surface, so that the mounting screw cannot be sufficiently tightened and the mounting strength of the range hood becomes weak.

The present invention has been made to solve the above-mentioned problems, and its purpose is to attach a range hood to a wall surface with sufficient strength even when the mounting screw is misaligned with the base material inside the wall or in the case of reforming. It is possible to attach the mounting hole of the range hood body to the protruding part of the mounting screw easily, the range hood body can be easily temporarily mounted and supported, and the temporary mounting strength of the mounting screw is strong, and the range hood body is stable.

Next, details of the fan box mounting portion will be described with reference to FIGS. 3 and 4. FIG. 3 is an enlarged front view of the portion where the blower box is attached, and FIG. 4 is a sectional view taken along line AA of FIG.
The wall mounting member 4 has a hollow box shape in which the back plate 42 and the front plate 43 are connected by the upper and lower connecting members 44 with a space therebetween. An upper portion 42a of the back plate 42 projects upward from an upper portion 43a of the front plate 43, and a screw insertion hole 40 is formed in the upper portion 42a.
The wall mounting member 4 has a screw hole 45 into which the mounting screw 6 is screwed. For example, a screw hole 45 is formed by fitting a nut 46 into the hole 42b of the rear plate 42 and the hole 43b of the front plate 43 so as to be attached.
The attachment portion 5 is a plate-shaped metal fitting, and is attached to the side surface 21c of the blower box 21 with screws, rivets, welding, or the like. The back surface 5a of the mounting portion 5 is flush with the back surface 21a of the blower box 21. The mounting portion 5 can be provided integrally with the blower box 21.

The mounting screw 6 includes a threaded portion 60 on one end side in the axial direction of the mounting screw 6, a trunk portion 61 which is continuous with the other axial end portion of the threaded portion 60 and which is axially intermediate to the mounting screw 6, and a shaft of the trunk portion 61. It has a screw head 62 which is continuous with the other end in the axial direction and is located on the other end side in the axial direction of the mounting screw 6.
The axially one side portion of the screw portion 60 is screwed into the screw hole 45 of the wall mounting member 4, and the axially other side portion (body portion side portion) of the screw portion 60 is the front plate 43 of the wall mounting member 4, that is, the wall. It projects from the side surface of the mounting member 4 opposite to the wall surface 3.
The body portion 61 has a diameter larger than that of the threaded portion 60, and one end surface 61a in the axial direction of the body portion 61, that is, the end surface 61a on the side of the threaded portion 60 projects in the direction perpendicular to the axial direction from the outer peripheral surface of the threaded portion 60. The end surface 61a is a tightening surface of the mounting screw 6. An end surface 61a of the body portion 61 on the threaded portion 60 side is a surface perpendicular to the axial direction of the mounting screw 6.
The outer peripheral surface 61b of the body portion 61 is a smooth surface having no unevenness in the axial direction. The body portion 61 has the same diameter in the axial direction, and the outer peripheral surfaces are parallel in the axial direction.

The screw head 62 has a larger diameter than the body 61, and one end surface 62a of the screw head 62 in the axial direction, that is, the end surface 62a of the screw head 62 on the body 61 side projects from the outer peripheral surface 61b of the body 61. ..
An end surface 62a of the screw head 62 on the body 61 side is perpendicular to the axial direction of the mounting screw 6. The screw head 62 has a rotation operation portion 62b that rotates the mounting screw 6.
The screw head 62 has a substantially hemispherical shape, and has a cross-shaped groove on the surface thereof, and the groove is the rotation operation portion 62b.
The present invention is not limited to this, and the screw head 62 may have a hexagonal shape. Alternatively, the screw head portion 62 may have the same diameter as the body portion 61, and a groove may be formed on the end surface of the screw head portion 62 to form a rotary operation portion.

The mounting portion 5 has a mounting hole 50 penetrating from the back surface 5 a to the front surface 5 b, that is, penetrating in the thickness direction of the mounting portion 5.
The mounting hole 50 includes a lower large-diameter hole portion 51 through which the screw head 62 of the mounting screw 6 is inserted in the axial direction, and an upper small-diameter hole portion 52 continuous with the upper portion of the inner peripheral surface of the lower large-diameter hole portion 51. It has a dharma shape.
The screw head 62 and the body portion 61 of the mounting screw 6 cannot be inserted through the upper small diameter hole portion 52 in the axial direction, but the screw portion 60 can be inserted through the axial direction. The inner peripheral surface upper portion 52a of the upper small diameter hole portion 52 contacts the outer peripheral surface of the screw portion 60.
The body portion 61 of the intermediate hole portion 53 that connects the upper inner diameter portion of the lower large diameter hole portion 51 and the lower portion of the inner small diameter portion of the upper small diameter hole portion 52 cannot pass in the direction perpendicular to the axis. However, the threaded portion 60 can pass in the direction perpendicular to the axis.

The inner peripheral surface upper portion 52a of the upper small diameter hole portion 52 of the mounting hole 50 is in contact with the upper peripheral portion of the screw portion 60. The screw portion 60 of the mounting screw 6 is screwed into the screw hole 45 of the wall mounting member 4 and tightened. Due to the tightening force of the mounting screw 6, the end surface 61a of the body portion 61 on the threaded portion 60 side contacts the front surface 5b of the mounting portion 5, and the back surface 5a is pressed against the front plate 43 of the wall mounting member 4.
As a result, the mounting portion 5 is fixed to the wall mounting member 4, and the range hood body 2 is fixedly mounted on the wall surface 3 with the mounting member 4 interposed.
As described above, since the mounting portion 5 of the range hood main body 2 is sandwiched between the body portion 61 of the mounting screw 6 and the wall mounting member 4 and is firmly fixed, the range hood main body 2 has the wall mounting member 4 interposed therebetween. It is stably attached to the wall surface 3.

Next, an embodiment of a method of attaching the cooker hood body 2 to the wall surface 3 will be described.
As shown in FIG. 4, the back plate 42 of the wall mounting member 4 is brought into contact with the wall surface 3, and the fixing screw 41 is screwed into the stud inside the wall from the screw insertion hole 40 of the back plate 42 to tighten the wall mounting member 4. It is fixed and attached to the wall surface 3.
At this time, by selecting the screw insertion hole 40 corresponding to the stud and screwing the fixing screw 41 into the stud from the selected screw insertion hole 40, the wall mounting member 4 can be attached at an arbitrary position regardless of the position of the stud.
The axially one side portion of the screw portion 60 of the mounting screw 6 is screwed into the screw hole 45 of the wall mounting member 4 by a length sufficient to obtain sufficient mounting strength, and the mounting screw 6 is temporarily mounted to the wall mounting portion 4. As a result, the mounting screw 6 can be firmly and temporarily mounted to the wall mounting member 4.

The temporarily installed mounting screw 6 has the other axial end 60a of the threaded portion 60, that is, the body side portion thereof protrudes from the front plate 43 of the wall mounting member 4, that is, the side surface opposite to the wall surface 3, and the threaded portion of the body portion 61. There is a gap S (FIG. 5) between the end surface 61a on the 60 side and the front surface of the wall mounting member 4. This gap S is larger than the thickness of the mounting portion 5.
When the mounting screw 6 is screwed into the screw hole 45, a positioning piece (gap gauge) is brought into contact with the front plate 43 of the wall mounting member 4, and the end surface 61a of the body portion 61 of the mounting screw 6 on the screw portion 60 side is brought into contact with the positioning piece. Therefore, the gap S between the end surface 61a of the body portion 61 on the screw portion 60 side and the front surface of the wall mounting member 4 may be set to a predetermined value. By doing so, the gap S can be easily set to a predetermined value.
The wall mounting member 4 may be mounted on the wall surface 3 after the mounting screw 6 is screwed into the screw hole 45 and temporarily mounted.

In this state, the installer lifts the range hood main body 2 and moves it in the up-down direction and the left-right direction, so that the mounting hole 50 is attached to the mounting screw 6 as shown by a two-dot chain line in FIG. Align 51 with screw head 62 axially. For example, the center 51a of the lower large diameter hole portion 51 is made to coincide with the center 62c of the screw head 62.
After that, the range hood body 2 is moved toward the wall surface 3 as indicated by the arrow a in FIG. 5, so that the lower large diameter hole portion 51 has the screw head portion as shown by the solid line in FIG. It passes through 62 and reaches the body 61.
In this state, the range hood body 2 is moved downward as shown by the arrow b in FIG. 6, and as shown by the alternate long and short dash line in FIG. 6, the intermediate hole portion 53 (the portion on the inner peripheral surface of the lower large diameter hole portion 51 ) Is brought into contact with the outer peripheral surface 61b of the body portion 61 and the mounting portion 5 is hooked on the mounting screw 6 to temporarily mount and support the range hood body 2.

After that, the range hood body 2 is moved toward the wall surface 3 as shown by the arrow c in FIG. 6, so that the attachment portion 5 has the intermediate hole portion 53 of the attachment hole 50 and the outer periphery of the body portion 61 of the attachment screw 6. It moves (slides) to the screw portion 60 side while sliding on the surface 61b.
Then, when the intermediate hole portion 53 of the mounting hole 50 passes through the body portion 61 of the mounting screw 6, the range hood main body 2 moves downward by its own weight as shown by an arrow d in FIG. 6, and the mounting portion 5 is a two-dot chain line. As shown by, the inner peripheral surface upper portion 52a of the upper small diameter hole portion 52 of the mounting hole 50 contacts the outer peripheral surface of the screw portion 60 of the mounting screw 6. At this time, the installer having the range hood body 2 feels that the mounting portion 5 has fallen from the outer peripheral surface 61b of the body portion 61 to the screw portion 60, and the inner peripheral surface of the upper small diameter hole portion 52 of the mounting hole 50. Since the builder can confirm that the upper portion 52a is in contact with the outer peripheral surface of the screw portion 60 of the mounting screw 6, there is no mounting mistake.

In this state, the mounting screw 6 is tightened, and the end face 61a of the body portion 61 on the screw portion 60 side is pressed against the front surface 5b of the mounting portion 5 as shown in FIG. The mounting portion 5 is fixed to the wall mounting portion 4 by being sandwiched by the portion 61, and the range hood main body 2 is fixed to the wall surface 3 with the wall mounting member 4 interposed therebetween.
Thereby, the range hood can be attached to the wall surface 3.
Since the wall mounting member 4 is used for mounting in this manner, the range hood body 2 can be mounted on the wall surface 3 with sufficient strength even when the mounting screw 6 is misaligned with the base material inside the wall or in the case of reforming. ..

Further, in the state where the mounting screw 6 is screwed into the screw hole 45 of the wall mounting member 4 and temporarily mounted, the other axial end 60a of the screw portion 60 and the body portion 61 project from the wall mounting member 4, so the screw portion 60 Since the length of the protruding portion of the mounting screw 6 from the wall mounting member 4 can be increased by screwing the screw into the screw hole 45 by a length that provides sufficient mounting strength, the mounting hole 50 of the mounting portion 5 can be screwed into the mounting screw 50. 6 is easily hooked to the protruding portion, and the temporary mounting strength of the mounting screw 6 is strong. Moreover, the mounting screw 6 can be sufficiently tightened.
Therefore, in the prior art, the protruding portion is only the other end portion 60a in the axial direction of the screw portion 60, but according to the present invention, the protruding portion is further lengthened by the body portion 61, so that the range hood body 2 is temporarily attached. It is easy to support, and the range hood body 2 can be stably temporarily mounted and supported. Moreover, the range hood body 2 can be firmly fixed and attached.

Further, since the end surface 61a of the body portion 61 on the screw portion 60 side is perpendicular to the axial direction of the mounting screw 6, when the mounting screw 6 is tightened, the end surface 61a of the body portion 61 uniformly contacts the mounting portion 5, Since the mounting portion 5 can be pressed against the wall mounting member 4 with a wider area, the range hood body 2 is in a stable mounted state.
Further, since the outer peripheral surface 61b of the body portion 61 is a smooth surface having no unevenness in the axial direction, there are obstacles when moving the mounting portion 5 along the outer peripheral surface 61b of the body portion 61 toward the screw portion 60 side. Therefore, it is easy to move the mounting portion 5 to the screw portion 60 side.

Further, since the body portion 61 has the same diameter in the axial direction, the attachment portion is attached by the weight of the range hood body 2 or the like in a state where the attachment hole 50 of the attachment portion 5 is in contact with the outer peripheral surface 61b of the body portion 61. A force for moving the mounting portion 5 away from the screw portion 60 does not act, and the mounting portion 5 can be easily moved to the screw portion 60 side.
Further, since the mounting screw 6 has the screw head portion 62 having a diameter larger than that of the body portion 61, the wall surface of the range hood body 2 is kept in contact with the mounting hole 50 of the mounting portion 5 on the outer peripheral surface 61b of the body portion 61. Even if a force in the direction of separating from 3 is applied, the end face 62a of the screw head 62 on the body portion 61 side does not come off and is not easily removed, which is safe.

FIG. 7 shows another embodiment of the mounting screw 6. The mounting screw 6 has a screw portion 60, a body portion 61, and a screw head 62, and the outer peripheral surface 61b of the body portion 61 has no unevenness in the axial direction. It is a smooth surface and has a taper shape in which the diameter on the screw portion 60 side is smaller than the diameter on the screw head 62 side.
With this mounting screw 6, with the mounting hole 50 of the mounting portion 5 being in contact with the outer peripheral surface 61b of the body portion 61, the force for moving the mounting portion 5 to the screw portion 60 side by the weight of the range hood body 2 or the like. Works, and a force in a direction away from the screw portion 60 does not work, so that it is easy to move the mounting portion 5 to the screw portion 60 side.

FIG. 8 shows a second embodiment of the mounting hole 50. The mounting hole 50 has a triangular shape having a bottom side at the bottom and an apex at the top.
The bottom side of the mounting hole 50 is the lower large diameter hole portion 51 through which the screw head 62 of the mounting screw 6 is axially inserted, and the apex side is the upper small diameter hole portion 52 through which the screw head 62 is not axially inserted. .. An intermediate portion between the bottom side and the apex of the mounting hole 50 is an intermediate hole portion 53 that connects the lower large diameter hole portion 51 and the upper small diameter hole portion 52.

FIG. 9 shows a third embodiment of the mounting hole 50. The mounting hole 50 includes a circular lower large diameter hole portion 51 through which the screw head 62 of the mounting screw 6 is inserted in the axial direction, and a screw head 62. Has a rectangular upper small-diameter hole portion 52 through which the screw portion 60 is inserted in the axial direction without being inserted in the axial direction. The portion is the intermediate hole portion 53.

Although not shown, the mounting hole 50 may be a single hole through which the screw head 62 and the body 61 of the mounting screw 6 are inserted in the axial direction. That is, the mounting hole 50 may have any shape as long as the screw head 62 and the body 61 are inserted in the axial direction and the upper portion of the inner peripheral surface is in contact with the outer peripheral surface of the screw portion 60.
In the above embodiment, the mounting hole 50 of the mounting portion 5 is brought into contact with the outer peripheral surface 61b of the body portion 61 of the mounting screw 6 so that the mounting hole 50 of the mounting portion 5 is pulled to the body portion 61 of the mounting screw 6. The mounting portion 5 was slid on the outer peripheral surface 61b of the body portion 61 and moved to the screw portion 60 side, but when the mounting hole 50 of the mounting portion 5 is hooked on the mounting screw 6, the mounting portion 5 is mounted. The hole 50 (the inner peripheral surface upper portion 52a of the upper small-diameter hole portion 52) may come into contact with the screw portion 60 of the mounting screw 6, but it may be that.
