DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] The details of the embodiment of the present invention will be described with reference to the drawings. In the following drawings, the same or corresponding parts are given the same reference numerals, and redundant description will not be repeated. The range hood according to the embodiment is referred to as a range hood 100.

[0009] (100 Range Hood Configurations) The configuration of the range hood 100 will be described below.

[0010] FIG. 1 is an exploded perspective view of a range hood 100. As shown in FIG. 1, the range hood 100 has a main body 10, a hood 20, an exhaust port fitting 30, and a jig 40. In the following, the first direction DR1 is defined as one of the horizontal directions, and the second direction DR2 is defined as the other horizontal direction perpendicular to the first direction DR1. In the following, the third direction DR3 is defined as a direction perpendicular to the first direction DR1 and the second direction DR2, that is, a vertical direction. The range hood 100 is attached to a wall W. The normal direction of the wall W is along the second direction DR2.

[0011] The main body 10 has an upper end and a lower end. The main body 10 has an upper wall 11, side walls 12 and 13, a front wall 14 and a rear wall 15. The upper wall 11 forms the upper end of the main body 10. The upper ends of the side walls 12 and 13 are continuous with the upper wall 11. The side walls 12 and 13 face each other with a gap in the first direction DR1. The upper ends of the front wall 14 and the rear wall 15 are continuous with the upper wall 11. The front wall 14 and the rear wall 15 face each other with a gap in the second direction DR2.

[0012] The internal space of the main body 10 is defined by a top wall 11, a side wall 12, a side wall 13, a front wall 14, and a rear wall 15. A fan 16 (not shown) is housed in the internal space of the main body 10. A through hole 11a is formed in the top wall 11. The through hole 11a communicates with the internal space of the main body 10. A screw hole 17 (not shown) is formed in the side wall 12 and the side wall 13.

[0013] The hood portion 20 is attached to the lower end of the main body portion 10. The hood portion 20 has an upper wall 21 and a bottom wall 22 (not shown in FIG. 1, see FIG. 10). A recess 22a (not shown) is formed in the bottom wall 22. In the recess 22a, the bottom wall 22 is recessed toward the upper wall 21. The range hood 100 further has a straightening plate 22b (not shown). The straightening plate 22b is attached to the hood portion 20 so as to face the bottom surface of the recess 22a with a gap therebetween. A through hole 20a (not shown) is formed in the hood portion 20. The through hole 20a penetrates the hood portion 20 along the third direction DR3 and communicates with the internal space of the main body portion 10.

[0014] The exhaust outlet device 30 has an exhaust inlet 31 (not shown) and an exhaust outlet 32. The exhaust outlet device 30 can be attached to the upper wall 11 so that the exhaust inlet 31 is connected to the through hole 11a and the exhaust outlet 32 ​​faces the first direction DR1. Note that the exhaust outlet device 30 can also be attached to the upper wall 11 so that the exhaust inlet 31 faces a direction other than the first direction DR1.

[0015] The jig 40 has a first member 41 and a second member 42. Fig. 2 is a front view of the first member 41. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2. As shown in Figs. 2 and 3, the first member 41 has a plate-shaped portion 43 and an upper end portion 44.

[0016] The plate-shaped portion 43 is a flat portion. The plate-shaped portion 43 is, for example, rectangular in shape with its longitudinal direction aligned with the fourth direction DR4. The fifth direction DR5 is a direction perpendicular to the fourth direction DR4, and the sixth direction DR6 is a direction perpendicular to the fourth direction DR4 and the fifth direction DR5. The plate-shaped portion 43 has a first end 43a and a second end 43b. The first end 43a and the second end 43b constitute both ends of the plate-shaped portion 43 in the sixth direction DR6. The second end 43b is an end opposite to the first end 43a.

[0017] The plate-shaped portion 43 has a first surface 43c and a second surface 43d. The first surface 43c and the second surface 43d constitute both end surfaces of the plate-shaped portion 43 in the fifth direction DR5. In other words, the first surface 43c and the second surface 43d constitute both end surfaces of the plate-shaped portion 43 in the thickness direction. The first surface 43c is a surface that comes into contact with the wall W when the first member 41 is attached to the wall W. The second surface 43d is the opposite surface to the first surface 43c.

[0018] A plurality of through holes 43e are formed in the plate-shaped portion 43. The through holes 43e penetrate the plate-shaped portion 43 along the fifth direction DR5. That is, the through holes 43e penetrate the plate-shaped portion 43 along the thickness direction. The first member 41 is attached to the wall W at the plate-shaped portion 43. More specifically, the first member 41 is attached to the wall W by inserting a fixing member such as a screw (not shown) into the through hole 43e and screwing the fixing member such as the screw inserted into the through hole 43e into a stud (reinforcement bar) inside the wall W. Which of the plurality of through holes 43e is to be used is appropriately selected depending on the position of the stud inside the wall W.

[0019] The fourth direction DR4 is aligned with the first direction DR1 when the first member 41 is attached to the wall W. In addition, the second end 43b is located above the first end 43a when the first member 41 is attached to the wall W.

[0020] The upper end 44 has a first portion 44a and a second portion 44b. The first portion 44a is connected to the second end 43b. The first portion 44a extends along the fifth direction DR5 so as to move away from the wall W when the plate-shaped portion 43 is attached to the wall W. That is, the first portion 44a extends along the direction from the first surface 43c to the second surface 43d. The second portion 44b is connected to the end of the first portion 44a opposite to the second end 43b. The second portion 44b extends upward along the sixth direction DR6 when the plate-shaped portion 43 is attached to the wall W. That is, the second portion 44b extends along the fifth direction DR5 so as to move away from the second end 43b. Thus, the upper end 44 is L-shaped in a cross-sectional view perpendicular to the fourth direction DR4.

[0021] A screw hole 44c is formed in the second portion 44b. The screw hole 44c penetrates the second portion 44b along the fifth direction DR5. That is, the screw hole 44c penetrates the second portion 44b along the thickness direction. Two notches 44d are formed at the end of the second portion 44b opposite to the first portion 44a. The two notches 44d are arranged at an interval in the fourth direction DR4.

[0022] The width of the first member 41 in the fourth direction DR4 is defined as a width WD. The width WD is appropriately selected according to the space where the range hood 100 is to be attached. The width WD is, for example, 600 mm, 750 mm, or 900 mm.

[0023] Fig. 4 is a front view of the second member 42. Fig. 5 is a first side view of the second member 42. Fig. 6 is a second side view of the second member 42. As shown in Figs. 4 to 6, the second member 42 has a plate-shaped portion 45, two engagement portions 46, and two fixing portions 47.

[0024] The plate-shaped portion 45 is a flat portion. The plate-shaped portion 45 is, for example, rectangular in shape with its longitudinal direction aligned with the seventh direction DR7. The eighth direction DR8 is a direction perpendicular to the seventh direction DR7, and the ninth direction DR9 is a direction perpendicular to the seventh direction DR7 and the eighth direction DR8. The plate-shaped portion 45 has a first end 45a and a second end 45b. The first end 45a and the second end 45b constitute both ends of the plate-shaped portion 45 in the seventh direction DR7. The second end 45b is an end opposite to the first end 45a.

[0025] The two engaging portions 46 are connected to the first end 45a and the second end 45b, respectively. The engaging portions 46 extend along a ninth direction DR9. A through hole 46a is formed in the engaging portion 46. The through hole 46a penetrates the engaging portion 46 along a seventh direction DR7. That is, the through hole 46a penetrates the engaging portion 46 along the thickness direction.

[0026] One of the engagement parts 46 is attached to the main body 10 by inserting a fixing member 48 (not shown) into the through hole 46a and screwing the inserted fixing member 48 into a screw hole 17 formed in the side wall 12. The other of the engagement parts 46 is attached to the main body 10 by inserting a fixing member 48 into the through hole 46a and screwing the inserted fixing member 48 into a screw hole 17 formed in the side wall 13. The fixing member 48 is, for example, a screw. With the second member 42 attached to the main body 10, the seventh direction DR7, the eighth direction DR8, and the ninth direction DR9 are aligned with the first direction DR1, the second direction DR2, and the third direction DR3, respectively.

[0027] The plate-shaped portion 45 has a first surface 45c and a second surface 45d (see FIG. 8). The first surface 45c and the second surface 45d constitute both end surfaces of the plate-shaped portion 45 in the eighth direction DR8. That is, the first surface 45c and the second surface 45d constitute both end surfaces of the plate-shaped portion 45 in the thickness direction. The first surface 45c faces the first member 41 (plate-shaped portion 43) when the second member 42 is attached to the main body 10 and is attached to the first member 41. The second surface 45d is the opposite surface to the first surface 45c. The first surface 45c is flush with the back wall 15, for example.

[0028] The engaging portion 46 protrudes upward from the upper wall 11 when the second member 42 is attached to the main body 10 (see FIG. 10). A recess 46b is formed in the engaging portion 46. The recess 46b is formed in a portion of the engaging portion 46 that protrudes upward from the upper wall 11 when attached to the main body 10. The recess 46b has a side surface 46c, a side surface 46d, and a bottom surface 46e. The side surface 46c and the side surface 46d face each other with a gap in the ninth direction DR9. The bottom surface 46e is continuous with the side surface 46c and the side surface 46d. The side surface 46c has a protrusion 46ca. The side surface 46c protrudes toward the side surface 46d. The protrusion 46ca is disposed with a gap from the bottom surface 46e in the eighth direction DR8.

[0029] The second portion 44b comes into contact with the side surface 46c, so that the engaging portion 46 is engaged with the upper end portion 44. More specifically, the second portion 44b is inserted between the convex portion 46ca and the bottom surface 46e, so that the engaging portion 46 is engaged with the upper end portion 44. With the engaging portion 46 engaged with the upper end portion 44, the second member 42 is slidable along the first direction DR1 relative to the first member 41. By sliding the second member 42 along the first direction DR1 relative to the first member 41, the engaging portion 46 fits into the notch 44d. With the engaging portion 46 engaged with the upper end portion 44, the side surface 46d faces the first portion 44a.

[0030] The fixing portion 47 is connected to the bottom surface 46e. The fixing portion 47 connected to one of the engaging portions 46 extends toward the other engaging portion 46 along the seventh direction DR7. The thickness direction of the fixing portion 47 is along the eighth direction DR8. An insertion hole 47a is formed in the fixing portion 47. The insertion hole 47a penetrates the fixing portion 47 along the eighth direction DR8. That is, the insertion hole 47a penetrates the fixing portion 47 along the thickness direction. FIG. 7 is an exploded perspective view of the jig 40. As shown in FIG. 7, the fixing member 49 is inserted into the insertion hole 47a with the engaging portion 46 engaged with the upper end portion 44, and the inserted fixing member 49 is screwed into the screw hole 44c.

[0031] Fig. 8 is a cross-sectional view of the jig 40. As shown in Fig. 8, the plate-shaped portion 43 is sandwiched between the wall W and the main body portion 10 (back wall 15) in a state in which the first member 41 is attached to the wall, the second member 42 is attached to the main body portion 10, and the engagement portion 46 is engaged with the upper end portion 44.

[0032] <Modification> In the above, an example has been described in which the jig 40 has the first member 41 and the second member 42, but the jig 40 does not have to have the second member 42. In this case, for example, the engagement portion 46 may form a part of the main body portion 10.

[0033] In the above, an example was described in which the top wall 11, the side wall 12, the side wall 13, the front wall 14, and the back wall 15 are flat, but at least one of the top wall 11, the side wall 12, the side wall 13, the front wall 14, and the back wall 15 does not have to be flat, and may be, for example, arched. In the above, an example was described in which the top wall 21, the bottom wall 22, the side wall 23, the side wall 24, the front wall 25, and the back wall 26 are flat, but at least one of the top wall 21, the bottom wall 22, the side wall 23, the side wall 24, the front wall 25, and the back wall 26 does not have to be flat, and may be, for example, arched.

[0034] (How to install Range Hood 100) A method for installing the range hood 100 will be described below.

[0035] Fig. 9 is a process diagram showing a method for installing the range hood 100. As shown in Fig. 9, the method for installing the range hood 100 includes a first member installing step S1, a second member installing step S2, a temporary placement step S3, a duct connecting step S4, and a jig fixing step S5.

[0036] In a first member attachment step S1, the first member 41 is attached to the wall W. In a second member attachment step S2, the first member 41 is attached to the main body 10. In a temporary placement step S3, the engagement portion 46 is engaged with the upper end portion 44, thereby temporarily attaching the main body 10, the hood portion 20, and the exhaust outlet fitting 30 to the wall W. The main body 10, the hood portion 20, and the exhaust outlet fitting 30 are temporarily placed in a position away from the duct 50 in the first direction DR1.

[0037] The duct 50 extends along the first direction DR1. The duct 50 has a duct inlet 51 at one end in the first direction DR1. The duct 50 is, for example, a spiral duct. Unlike a flexible duct, a spiral duct is a duct that is difficult to deform. The exhaust outlet device 30 may be attached to the upper wall 11 after the temporary placement step S3 is performed. At this time, the engagement portion 46 is not fitted into the cutout 44d.

[0038] Fig. 10 is a front view illustrating the duct connection step S4. As shown in Fig. 10, in the duct connection step S4, the main body 10, the hood 20, and the exhaust port fitting 30 are slid along the first direction DR1 relative to the first member 41 (see the arrow in Fig. 10). As a result, the exhaust outlet 32 ​​is connected to the duct inlet 51. At this time, the engagement portion 46 is fitted into the notch 44d. In the jig fixing step S5, the fixing member 49 is inserted into the insertion hole 47a, and the fixing member 49 inserted into the insertion hole 47a is screwed into the screw hole 44c, thereby fixing the second member 42 to the first member 41. With the above, the attachment of the range hood 100 to the wall W is completed.

[0039] FIG. 11 is an enlarged front view of the jig 40 according to the modified example. As shown in FIG. 11, in a state where the second member 42 is attached to the first member 41, the width of the insertion hole 47a in the first direction DR1 may be larger than the width of the insertion hole 47a in the third direction DR3. From another perspective, the insertion hole 47a may be an elongated hole whose longitudinal direction is along the first direction DR1. The notch 44d may have a width in the first direction DR1 such that the engagement portion 46 fits within the range where the insertion hole 47a and the screw hole 44c overlap in the first direction DR1. In this case, the attachment position of the range hood 100 can be finely adjusted after the exhaust port tool 30 is connected to the duct 50.

[0040] (Effects of Range Hood 100) The effects of the range hood 100 will be described below.

[0041] If it is difficult to deform the duct 50 (for example, if the duct 50 is a spiral duct), the duct 50 may become an obstacle when installing the range hood, causing problems in installing the range hood. In this regard, in the range hood 100, the second member 42 is slidably attached to the first member 41 attached to the wall W. Therefore, in the range hood 100, the exhaust outlet 32 ​​and the duct inlet 51 can be connected by temporarily placing the range hood 100 at a position away from the duct 50 and then sliding it. In this way, with the range hood 100, even if the duct 50 is difficult to deform, it is possible to easily connect the duct 50.

[0042] In the range hood 100, the engagement portion 46 protrudes above the upper wall 11, so the worker can proceed with the work while visually checking the engagement portion between the engagement portion 46 and the upper end portion 44. Therefore, the range hood 100 can be easily temporarily placed on the first member 41. In addition, the situation of the place where the range hood 100 is installed varies. Therefore, it is necessary to use a first member 41 having a different width WD according to the situation of the place where the range hood 100 is installed. In the range hood 100, even when a first member 41 with a different width WD is used, the engagement portion 46 can be engaged with the upper end portion 44 without changing the second member 42, and the installation can be performed.

[0043] In the range hood 100, when the engaging portion 46 is engaged with the upper end portion 44, the side surface 46d faces the first portion 44a. Therefore, even if a force is suddenly applied from below to the range hood 100 while the engaging portion 46 is engaged with the upper end portion 44, the side surface 46d and the first portion 44a come into contact with each other, and the engaging portion 46 is unlikely to come off the upper end portion 44. Therefore, the range hood 100 can be installed safely.

[0044] With the second member 42 attached to the first member 41, a moment acts on the first member 41 due to the weight of the range hood 100, moving the upper end portion 44 side away from the wall W. In the range hood 100, since the plate-shaped portion 43 is sandwiched between the main body 10 (back wall 15) and the wall W, a reaction force in a direction that cancels out the moment acts on the plate-shaped portion 43 from the wall W. Therefore, in the range hood 100, it is possible to suppress deformation of the first member 41 caused by its weight and sagging associated with the deformation.
