Description

The present invention relates to a range hood and a mounting member for the range hood.

The range hood is installed above the cooking cooker in order to discharge oil smoke and the like generated from the cooking cooker in the kitchen to the outside during cooking. As such a range hood, a wall-fixed type that is fixedly installed on a wall surface near the ceiling is known.
For example, the range hood described in Patent Document 1 has an L-shaped mounting bracket attached to the upper surface of a box-shaped main body case containing a fan or the like, and the other side of the mounting bracket is attached to the wall surface. It is fixed.

JP-A-2015-68536

Since the mounting bracket described in Patent Document 1 is mounted only on the upper surface of the main body case, it is necessary to mount it on the upper surface with a wide mounting area in order to increase the mounting strength and the supporting strength with respect to the main body case. Therefore, the mounting bracket becomes large, and it becomes difficult to mount the mounting bracket in advance at the manufacturing stage of the range hood. Therefore, it is necessary to attach the mounting bracket to the main body case at the installation site of the range hood, and the work process at the installation site increases. Further, even if the mounting posture of the mounting bracket with respect to the upper surface of the main body case can be set appropriately, it is difficult to properly set the mounting posture with respect to other surfaces (side surface, rear surface, etc.) of the main body case, and it is difficult to set the mounting posture with respect to the other surface (side surface, rear surface, etc.) of the main body case. Coupled with this, there is a high possibility that the mounting bracket will be mounted in a state of being tilted with respect to the other surface.

An object of the present invention is to provide a range hood in which the mounting member can be miniaturized and the mounting member can be mounted in advance on the main body case of the range hood in an appropriate mounting posture at the manufacturing stage.

A range hood according to a certain viewpoint includes a main body case having a rear surface, an upper surface, and left and right side surfaces and accommodating a fan, and a mounting member for mounting the main body case on a wall surface.
The mounting member includes three fixing pieces fixed to each of the rear surface, the upper surface, and the side surface at a corner portion of the main body case where the rear surface, the upper surface, and the side surface are abutted against each other, and the wall surface. It is equipped with a mounting piece that can be attached to.

Since the mounting member includes three fixing pieces that are fixed to the rear surface, the upper surface, and the side surface at the corner of the main body case, each of the fixing pieces is compared with the case where the fixing pieces are attached to only one surface of the main body case. The mounting area of the fixed piece with respect to the surface can be reduced, and as a result, the mounting member itself can be miniaturized. Therefore, it is possible to attach the mounting member to the main body case in advance at the manufacturing stage of the range hood, and it is possible to only mount the mounting member on the wall surface at the installation site of the range hood. Therefore, the workability of the range hood can be improved. Further, since the mounting member is fixed to the three surfaces at the corners of the main body case, it becomes easy to appropriately set the mounting posture with respect to each surface.

Preferably, the mounting piece is directly connected to at least two of the three fixing pieces.
With this configuration, the mounting piece can be firmly attached to two of the three surfaces of the main body case, and the main body case can be attached to the wall surface in a stable state via the mounting piece.

Preferably, the mounting piece is provided with a contact portion that is long in the vertical direction and abuts on the wall surface, and a bent portion that bends forward from the left and right side portions of the contact portion.
With this configuration, the bending rigidity of the mounting piece in the front-rear direction can be increased, and the main body case can be stably mounted on the wall surface.

Preferably, the fixing piece fixed to the side surface extends forward from the bent portion.
With this configuration, the fixing piece fixed to the side surface of the main body case can function as a bending portion for increasing the bending rigidity of the mounting piece.

Preferably, the mounting piece is provided with a contact portion having a vertical length exceeding the upper surface from the lower side of the rear surface and abutting against the wall surface, and a portion of the contact portion beyond the upper surface. A mounting hole for inserting a mounting tool for mounting the mounting piece is formed on the wall surface.
With this configuration, the abutting portion of the mounting piece is fixed to the wall surface at a portion of the mounting hole arranged at a position beyond the upper surface of the main body case, and abuts on the wall surface in a wide range below the mounting hole. The wall surface will stably receive the load of the main body case. Further, since the contact portion is arranged at a position overlapping the lower case in the vertical direction, a sufficient contact area with respect to the wall surface can be secured even if the amount of protrusion of the mounting piece from the upper surface of the lower case is reduced. .. Therefore, by adopting the above configuration, the size of the mounting member can be reduced.

The mounting member of the range hood according to another viewpoint is a mounting member for mounting the main body case in which the fan is housed on the wall surface in the range hood.
At the corner where the rear surface, the upper surface, and the side surface of the main body case abut against each other, three fixing pieces fixed to each of the rear surface, the upper surface, and the side surface, and a mounting piece attached to the wall surface are provided. ing.

According to the present invention, the mounting member can be miniaturized, the mounting member can be mounted in advance on the main body case of the range hood at the manufacturing stage, and the mounting posture of the mounting member with respect to the main body case can be appropriately set.

[Mounting structure of range hood 10]
FIG. 3 is a side view of the range hood 10. The range hood main body 12 is attached to the wall surface Wb on the back side by the attachment members 41 and 42. The mounting members 41 and 42 include a first mounting member 41 for mounting the lower case 33 of the main body case 31 on the wall surface Wb and a second mounting member 42 for mounting the upper case 34 of the main body case 31 on the wall surface Wb. have.

As shown in FIG. 1, the second mounting member 42 is provided over the entire width in the left-right direction on the upper surface of the upper case 34. As shown in FIG. 3, the second mounting member 42 is formed in a substantially L shape in a side view, and has a horizontally arranged fixing piece 42a and a vertically arranged mounting piece 42b. .. Then, the fixing piece 42a is fixed to the upper surface of the upper case 34 by a fixing tool 48 such as a screw or a rivet, and the mounting piece 42b is fixed to the wall surface Wb by a fixing tool 49 such as a screw.

4 is a side view of the first mounting member 41, FIG. 5 is a plan view of the first mounting member 41, and FIG. 6 is a rear view of the first mounting member 41. These FIGS. 4 to 6 show the first mounting member 41 on one of the left and right sides (right side). Since the first mounting member 41 on the left and right other side (left side) has the same configuration as the first mounting member 41 on the left and right one side except that it is formed symmetrically with a mirror image, detailed description thereof will be omitted. ..

The first mounting member 41 is fixed to the corners C at the rear upper ends on both the left and right sides of the lower case 33. Further, the first mounting member 41 has a mounting piece 43 mounted on the wall surface Wb and fixing pieces 44, 45, 46 fixed to the lower case 33, and is formed by bending a metal plate material. ing.

The mounting piece 43 includes a contact portion 51 and a bent portion 52. The contact portion 51 is made of a rectangular plate material elongated in the vertical direction. As shown in FIG. 5, the contact portion 51 is arranged behind the rear surface 33a of the lower case 33 with a gap, directly contacts the wall surface Wb, and is attached to the wall surface Wb.

As shown in FIG. 4, the lower end of the contact portion 51 is arranged at a position substantially coincident with the lower end of the lower case 33. The upper end of the contact portion 51 extends upward beyond the upper surface 33b of the lower case 33, and protrudes upward from the upper surface 33b. In other words, the contact portion 51 is arranged at a position overlapping the lower case 33 in the vertical direction.

As shown in FIG. 6, an attachment hole 53 for inserting an attachment 49 such as a screw for attaching the abutting portion 51 to the wall surface Wb is formed in the upper part of the abutting portion 51. The mounting hole 53 is formed from an insertion hole portion 53a having a diameter through which the head of the mounting tool 49 can be inserted and from the upper edge of the insertion hole portion 53a upward, and is smaller than the head of the mounting tool 49. It is provided with a drop groove 53b having a width.

As shown in FIGS. 4 and 5, the bent portion 52 is bent forward from both the left and right sides of the contact portion 51. The bent portion 52 functions as a rib that increases the bending rigidity of the contact portion 51 in the front-rear direction.

The fixing pieces 44, 45, 46 are the first fixing piece 44 fixed to the side surface 33c of the lower case 33, the second fixing piece 45 fixed to the rear surface 33a of the lower case 33, and the upper surface of the lower case 33. It is composed of a third fixing piece 46 fixed to 33b.

The first fixing piece 44 extends further forward along the side surface 33c of the lower case 33 from the bent portions 52a arranged on the left and right outer sides of the mounting piece 43. The first fixing piece 44 has a vertical length extending over the vertical height of the lower case 33. The upper part and the lower part of the first fixing piece 44 are fixed to the side surface 33c of the lower case 33 by a fixing tool 48 such as a screw or a rivet.

As shown in FIGS. 5 and 6, the second fixing piece 45 is bent inward from the bent portion 52b arranged on the left and right inside of the mounting piece 43 along the rear surface 33a of the lower case 33. The second fixing piece 45 has a length in the vertical direction over the height of the lower case 33. The upper part and the lower part of the second fixing piece 45 are fixed to the rear surface 33a of the lower case 33 by a fixing tool 48 such as a screw or a rivet.

As shown in FIG. 5, the third fixing piece 46 is bent inward in the left-right direction from the upper end edge of the first fixing piece 44 along the upper surface 33b of the lower case 33. The third fixing piece 46 is fixed to the upper surface 33b of the lower case 33 by a fixing tool 48 such as a screw or a rivet.

From the above, in the first mounting member 41, in the corner portion C where the rear surface 33a, the upper surface 33b, and the side surface 33c of the lower case 33 are butted, the first to third fixing pieces 44, 45, and 46 are the lower cases, respectively. It is fixed to each surface 33c, 33a, 33b of 33. Therefore, the mounting area of each of the fixing pieces 44, 45, 46 with respect to each of the surfaces 33c, 33a, 33b can be formed smaller than that of the case where the fixing piece is fixed to only one surface of the lower case 33. As a result, the entire first mounting member 41 can be miniaturized.

When the first mounting member 41 becomes smaller, it becomes possible to mount the first mounting member 41 on the main body case 31 in advance at the manufacturing stage of the range hood 10. Therefore, at the installation site of the range hood 10, the work of fixing the first mounting member 41 to the main body case 31 can be omitted, and the first mounting member 41 previously mounted on the main body case 31 can be attached to the wall surface Wb. Since only the installation work needs to be performed, the workability can be improved.

In the first mounting member 41, since the fixing pieces 44, 45, 46 are fixed to the respective surfaces 33c, 33a, 33b at the corner portion C of the lower case 33, the first attachment to the respective surfaces 33c, 33a, 33b is performed. The posture of the member 41 can be set appropriately. Further, since the first mounting member 41 is mounted on the lower case 33 at the manufacturing stage of the range hood 10, each of the first mounting members 41 is mounted on the lower case 33 at the installation site of the range hood 10 as compared with the case where the first mounting member 41 is mounted on the lower case 33. It becomes easy to appropriately set the mounting posture with respect to the surfaces 33c, 33a, 33b.

The flexural rigidity of the mounting piece 43 of the first mounting member 41 is increased by the bending portions 52 that bend forward on both the left and right sides of the contact portion 51. Therefore, when the mounting piece 43 of the first mounting member 41 is mounted on the wall surface Wb, it is possible to prevent the mounting piece 43 from bending back and forth due to the load of the range hood 10, and the main body case 31 can be stabilized. It can be attached to the wall surface Wb. Further, the first fixing piece 44 extends forward from one of the bent portions 52, and substantially functions as a rib for reinforcing the mounting piece 43. Therefore, it is possible to further increase the rigidity of the mounting piece 43.

The first mounting member 41 has a form in which the first and second fixing pieces 44 and 45 are directly connected to the mounting piece 43, and only the third fixing piece 46 is via the first fixing piece 44. Is indirectly connected to the mounting piece 43. By directly connecting the mounting piece 43 to the two fixing pieces 44 and 45 in this way, the lower case 33 can be mounted on the wall surface Wb in a more stable state.

The mounting piece 43 of the first mounting member 41 has a mounting hole 53 formed in a portion exceeding the upper surface 33b of the lower case 33, and a wall surface below the mounting hole 53 in a wide range exceeding the height of the lower case 33. It is in contact with Wb. Therefore, the load of the main body case 31 can be received by the wall surface Wb in this range. Further, since the contact portion 51 is arranged at a position overlapping the lower case 33 in the vertical direction, even if the amount of protrusion of the mounting piece 43 from the upper surface 33b of the lower case 33 is reduced, the contact portion 51 is sufficiently relative to the wall surface Wb. The contact area can be secured, and the size of the first mounting member 41 can be further reduced.

FIG. 7A is a schematic perspective view showing a state in which the lower case 33 is unfolded, and FIG. 7B is a perspective view showing a state in which the lower case 33 is assembled. The rear surface 33a, the upper surface 33b, and the side surface 33c of the lower case 33 are formed by bending a single plate material. Specifically, it is formed by bending the portions forming the side surface 33c and the rear surface 33a downward (see arrows) from the portion forming the upper surface 33b of one plate material. The first mounting member 41 has a function of connecting the side surface 33c and the rear surface 33a, which are not directly connected, by being mounted on the corner portion C of the lower case 33. Therefore, it is not necessary to separately provide a member for connecting the side surface 33c and the rear surface 33a, and the number of parts can be reduced. Further, the first mounting member 41 covers the space between the rear surface 33a and the side surface 33c of the lower case 33 from the outside, and closes the gap between the two. Therefore, it is not necessary to separately provide a member for closing the gap between the rear surface 33a and the side surface 33c.

It should be considered that the embodiments disclosed this time are exemplary in all respects and not restrictive. The scope of the present invention is shown by the scope of claims rather than the above description, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
For example, the first mounting member 41 may be mounted at a corner of the upper case 34 in the main body case 31. Further, the main body case 31 is not limited to the one composed of the upper case 34 and the lower case 33, and may be formed in the box shape of one rectangular parallelepiped (or cube).
