[0003] [Patent Document 1] JP 2008-196801 A Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional range hoods have a problem in that the filter mounting portion is made separately from the hood and attached to the hood top plate, resulting in poor productivity. In order to solve this problem, the present inventors attempted to improve productivity by forming the filter mounting portion integrally with the hood top plate through drawing. However, drawing the hood top plate causes distortion in the hood top plate, which creates a gap between the hood top plate and the main body, allowing oily smoke and other liquids to be sucked in through the gap when the range hood is in operation.In addition, when cleaning the hood, cleaning fluid and other liquids may seep into the hood through the gap.

[0005] The present invention has been made to solve the above-mentioned problems, and its object is to provide a range hood in which the hood top plate is drawn to integrally mold the filter mounting section, thereby improving productivity, suppressing distortion of the hood top plate due to drawing, and eliminating gaps between the hood top plate and the main body. [Means for solving the problem]

[0006] The first range hood of the present invention comprises a hood, a main body attached to a hood top plate of the hood, a filter attached to the hood, and a blower provided on the main body, the hood top plate having an opening communicating with an intake part of the blower, and heating and adjustment are performed by driving the blower. Reason and a filter for collecting oily smoke generated in a range hood and discharging it outside the range hood through the filter. The range hood is characterized in that the hood top plate has a filter mounting portion formed by drawing around the opening, an upward protrusion that is continuously provided so as to surround the periphery of the filter mounting portion, and a fixing portion for fixing the main body, the main body has a flange portion having a fixed portion that is fixed to the hood, and the main body is attached to the hood top plate by fixing the fixed portion and the fixing portion with a fastening member, the underside of a part of the flange portion is in contact with a part of the protrusion, the flange portion that is not in contact with the protrusion is in contact with the hood top plate and is located outside the protrusion that is not in contact with the flange portion.

[0007] The second range hood of the present invention includes a hood, a main body attached to a hood top plate of the hood, a filter attached to the hood, and a blower provided on the main body, and the hood top plate has an opening communicating with an intake part of the blower, and heating and adjustment are performed by driving the blower. By reasonThis range hood collects generated oily smoke inside the hood and expels it outside the unit through the filter, and the hood top plate has a filter mounting portion formed by drawing around the opening, an upward protrusion that is continuously arranged to surround the filter mounting portion, and a fixing portion for fixing the main body, and the main body has a flange portion having a fixed portion that is fixed to the hood, and the main body is attached to the hood top plate by fixing the fixed portion and the fixing portion with a fastening member, and the underside of at least a part of the flange portion is in contact with at least a part of the protrusion.

[0008] In the range hood of the present invention, the convex portion has a front side convex portion, a rear side convex portion, a right side convex portion, and a left side convex portion, and the flange portion has a front side flange portion, a rear side flange portion, a right side flange portion, and a left side flange portion, and the range hood can be one in which the underside of the front side flange portion is in contact with at least a portion of the front side convex portion. This improves the adhesion between the hood top plate and the front side of the main body, which is particularly effective in range hoods where oily smoke, cleaning fluids, and other liquids often flow toward the main body from the front side.

[0009] In the range hood of the present invention, the convex portion in contact with the lower surface of the flange portion may have a fixing portion relief portion that avoids the fixing portion. According to this, the lower surface of the flange portion comes into strong contact with the protrusion, and the flange portion can be firmly fixed.

[0010] In the range hood of the present invention, the convex portion having the fixing portion recess can be such that the fixing portion and the portion other than the fixing portion recess are provided in the same straight line. This improves the adhesion between the underside of the flange and the protrusion, eliminating any gaps between the hood top plate and the main body.

[0011] In the range hood of the present invention, the fixing portion recess may be provided on the opposite side of the fixing portion to the filter attachment portion. According to this, the relief portion of the fixing portion acts as a dike, making it difficult for liquid to flow to the fixing portion, and preventing liquid from entering the hood from the fixing portion.

[0012] In the range hood of the present invention, a wiring hole is formed in the front side portion of the filter mounting part, and the front side convex portion facing the front side portion of the filter mounting part of the convex portion has a hole relief portion that avoids the wiring hole, and the hole relief portion can be provided on the front side of the wiring hole. This allows wiring to run from the hood to the main body through the wiring hole. In addition, the hole relief portion acts as a bank, making it difficult for liquid to flow to the wiring hole, and preventing liquid from entering the hood through the wiring hole.

[0013] In the range hood of the present invention, the front side convex portion has a fixing portion clearance portion to avoid the fixing portion and a hole clearance portion to avoid the wiring hole, the front side convex portion is arranged in a straight line with the fixing portion and a portion other than the fixing portion clearance portion and the hole clearance portion, and the range hood can be such that the underside of the front flange portion is in contact with the portion of the front side convex portion other than the fixing portion clearance portion and the hole clearance portion. This is particularly effective in range hoods that have electrical equipment mounted on the front side of the hood, as oily smoke and liquids such as cleaning fluids often flow toward the main body from the front side.

[0014] In the range hood of the present invention, the convex portions can have two convex portions opposing each other in the front and rear side directions and two convex portions opposing each other in the right and left side directions, making the range hood symmetrical in the right and left side directions. This allows the protrusions to be well balanced in the right and left side directions, and the main body to be attached to the hood in a well balanced manner in the right and left side directions.

[0015] In the range hood of the present invention, the convex portions can have one pair of two convex portions facing each other in the front-to-rear side directions and two other pair of convex portions facing each other in the right-to-left side directions, and the range hood can be configured so that at least one or the other pair of facing convex portions is in contact with the underside of the flange portion. This allows the main body to be attached to the hood top plate in a well-balanced manner. Effect of the Invention

[0016] According to the first and second range hoods of the present invention, the filter attachment portion is integrally formed by drawing the hood top plate, thereby improving productivity. In addition, by providing the convex portion, distortion of the hood top plate can be suppressed when the hood top plate is drawn to integrally mold the filter mounting portion, so that no gaps due to distortion are generated between the hood top plate and the main body. Furthermore, since the convex portion faces upward, it acts as a barrier to stop the flow of liquid, and can prevent liquid flowing over the upper surface of the hood top plate from flowing toward the filter mounting portion. In addition, since the contact area between the underside of the flange and the convex portion is a linear contact with a small contact area, the force of fixing the main body to the hood top plate and the weight of the main body improves the adhesion between the contact area between the underside of the flange and the convex portion, eliminating gaps and preventing liquid from entering through the contact area. Therefore, when the range hood is in operation, air is not sucked in between the hood top plate and the main body, and liquid does not seep into the hood from between the hood top plate and the main body.

[0017] According to the first range hood of the present invention, the flange portion that is not in contact with the protruding portion is in contact with the hood top plate, so that the main body can be stably attached. In addition, the flange portion that is not in contact with the convex portion is located outside the convex portion that the flange portion is not in contact with, so it has a positioning function when attaching the main body to the hood top plate, making it easy to attach the main body.

[0019] BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a range hood according to an embodiment of the present invention; The overall configuration of the range hood will be described with reference to Fig. 1 to Fig. 7. Fig. 1 is an overall perspective view of the range hood, Fig. 2 is an overall front view of the range hood, Fig. 3 is an overall plan view of the range hood, Fig. 4 is an overall bottom view of the range hood, Fig. 5 is a bottom view of the range hood with the filter and baffle plate removed, Fig. 6 is an AA cross-sectional view of the range hood shown in Fig. 2, and Fig. 7 is a BB cross-sectional view of the range hood shown in Fig. 2. As shown in Figures 1 to 3, range hood 1 includes a hood 2 and a main body 3. Hood 2 is box-shaped with an open bottom and is made up of a hood top plate 20 and a peripheral plate 21, and peripheral plate 21 has a rectangular planar shape with a front side plate 22, a rear side plate 23, a left side plate 24, and a right side plate 25. The front side is the side facing the person cooking when range hood 1 is installed, the rear side is the side facing the front side, the left side is the side to the left of the person cooking when range hood 1 is installed, and the right side is the side to the right of the person cooking when range hood 1 is installed.

[0020] The main body 3 is in the shape of a box with an open bottom and is comprised of an upper panel 30 and a peripheral panel 31 . The peripheral panel 31 has a front side panel 32 , a rear side panel 33 , a left side panel 34 and a right side panel 35 . As shown in Figs. 5 and 6, the hood top plate 20 has an opening 26 near the rear side plate 23, and the filter attachment portion 4 is integrally formed around the opening 26 by drawing. A protrusion 5 is provided continuously around the periphery of the filter attachment portion 4, and the protrusion 5 is an upward protrusion that protrudes above the upper surface 20a of the hood top plate 20. The hood top plate 20 is drawn to integrally form the filter attachment portion 4, thereby improving productivity. Providing the protrusions 5 can suppress distortion of the hood top plate 20 when the hood top plate 20 is drawn to integrally form the filter attachment portion 4 .

[0021] As a result, no gap is generated between the hood top plate 20 and the main body 3 due to distortion, air is not sucked in between the hood top plate 20 and the main body 3 when the range hood is in operation, and liquid does not seep into the hood 2 from between the hood top plate 20 and the main body 3. Furthermore, since the protrusion 5 faces upward, it acts as a dike that stops the flow of liquid, and can prevent liquid flowing over the upper surface of the hood top plate 20 from flowing toward the filter attachment portion 4 side.

[0022] 6, a filter 27 is attached to the filter attachment portion 4, and a straightening plate 28 is attached inside the hood 2. The straightening plate 28 is located below the filter 27 and covers the filter 27. As shown in FIG. 4, an outer peripheral surface 28a of the straightening plate 28 and an inner surface 21a of the peripheral plate 21 of the hood 2 are spaced apart from each other to form an inlet portion 29. As shown in FIG. 6, a blower 6 is provided inside the main body 3. The blower 6 has a motor 60 and a fan 61, and as the fan 61 rotates, it sucks in air from an inlet portion 62. The inlet portion 62 communicates with the opening 26. By rotating the fan 61 with the motor 60 to drive the blower 6, oily smoke generated during cooking or the like is collected in the hood 2 through the inlet 29, sucked in by the blower 6 through the filter 27, and exhausted outside the machine. For example, it is exhausted to the outdoors through a duct or the like (not shown).

[0023] 6, electrical equipment 7 is attached to the inside of hood 2 near front side plate 22. Electrical equipment 7 has operating parts 70 such as switches and lights 71. An electrical equipment cover 72 for covering the electrical equipment 7 is attached near the front side plate 22 inside the hood 2 to prevent oily smoke collected inside the hood 2 from reaching the electrical equipment 7. Since electrical wiring (not shown) is conducted between the electrical equipment 7 and the main body 3, as shown in FIG. 5, a wiring cover 73 is attached to the underside 20b of the hood top plate 20 to prevent oily smoke from reaching the electrical wiring. As shown in Figures 5 and 7, the front end of the wiring cover 73 protrudes toward the electrical equipment 7 through a hole 74 in the electrical equipment cover 72, and the rear end of the wiring cover 73 protrudes toward the main body 3 through a wiring hole 75 formed in the front portion 4a of the filter mounting portion 4.

[0024] The filter attachment portion 4 and the protrusion 5 will be described in detail with reference to Figures 8 and 9. Figure 8 is an enlarged view of part C in Figure 5, and Figure 9 is an enlarged view of part D in Figure 6. In Figure 8, the rear end of the wiring cover 73 is not shown, but wiring holes 75 are shown. 8, filter mounting portion 4 has a rectangular planar shape and is made up of a front-side filter mounting portion 40 on the front side plate 22 side, a rear-side filter mounting portion 41 on the rear side plate 23 side, a left-side filter mounting portion 42 on the left side plate 24 side, and a right-side filter mounting portion 43 on the right side plate 25. Front-side filter mounting portion 40 is the front portion 4a. 9, each filter attachment portion 40, 41, 42, 43 has a generally upwardly facing U-shape with a downward portion 44 continuing with the hood top plate 20, a horizontal portion 45 continuing with the downward portion 44, and a hook-shaped filter support portion 46 continuing with the horizontal portion 45. The filter support portions 46 form the opening 26. The filter 27 is attached across each of the filter support portions 46.

[0025] As shown in Fig. 8, the upward protrusion 5 has a rectangular planar shape consisting of a front protrusion 50 provided along the front filter mounting part 40, a rear protrusion 51 provided along the rear filter mounting part 41, a left protrusion 52 provided along the left filter mounting part 42, and a right protrusion 53 provided along the right filter mounting part 43. Each of the protrusions 50, 51, 52, 53 has a linear shape, but when the planar shape of the filter mounting part 4 is a circle, an ellipse, or the like, each of the protrusions 50, 51, 52, 53 is curved like an arc. In other words, the upward protrusion 5 has two protrusions facing each other in the front and rear side directions and two protrusions facing each other in the right and left side directions, is symmetrical in the right and left side directions, is provided along the filter mounting part 4, and desirably has the same planar shape as the filter mounting part 4. This allows the protrusions 5 to be well balanced in the right and left side directions, and the main body 3 can be attached to the hood 2 in a well balanced manner in the right and left side directions.

[0026] A fixing portion 10 for fixing the main body 3 is provided around the filter attachment portion 4 on the hood top plate 20. The fixing portion 10 is a hole that penetrates the hood top plate 20 and through which a fastening member 11 such as a screw passes. The fixing portion 10 is not limited to this and can be, for example, a screw hole into which the fastening member 11 is screwed. The fixing portion 10 has a plurality of front side fixing portions 10a provided along the front side filter mounting portion 40, a plurality of left side fixing portions 10b provided along the left side filter mounting portion 42, and a plurality of right side fixing portions 10c provided along the right side filter mounting portion 43. The fixing portion 10 is not limited to this, and can be provided anywhere around the filter mounting portion 4.

[0027] Since the left surface side fixing portion 10b is provided on the opposite side of the left surface side convex portion 52 from the left surface side filter mounting portion 42, i.e., on the outside, the left surface side convex portion 52 can be provided in a position close to the left surface side filter mounting portion 42 regardless of the left surface side fixing portion 10b. Since the right surface side fixing portion 10c is provided on the opposite side of the right surface side convex portion 53 from the right surface side filter mounting portion 43, i.e., on the outside, the right surface side convex portion 53 can be provided in a position close to the right surface side filter mounting portion 43 regardless of the right surface side fixing portion 10c. According to this, when the hood top plate 20 is drawn to integrally form the filter attachment portion 4, distortion of the hood top plate 20 can be further suppressed.

[0028] The front side protrusion 50 has a fixing portion clearance portion 50a for avoiding the front side fixing portion 10a, so that the front side protrusion 50 is not discontinuous due to the front side fixing portion 10a. The portion 50b of the front side protrusion 50 other than the fixed portion clearance portion 50a and the front side fixed portion 10a are provided on the same straight line. On the same straight line includes being on the same straight line and being slightly deviated from being on the same straight line. The fixing portion relief portion 50a is provided on the opposite side of the front side fixing portion 10a to the front side filter attachment portion 40. In other words, the fixing portion relief portion 50a protrudes in an arc shape toward the front side plate 22 of the hood 2. The fixing portion relief portion 50a is not limited to an arc shape, and may be a mountain shape, a trapezoid shape, or the like.

[0029] According to this, the fixing part relief portion 50a acts as a dike that stops liquid from flowing to the front side fixing part 10a, and liquid flowing on the upper surface 20a of the hood top plate 20 can be prevented from penetrating from the front fixing part 10a into the hood 2. For example, it is possible to prevent cleaning liquid from penetrating into the hood 2 when cleaning the hood top plate 20. In addition, the front side convex portion 50 can be provided in a position close to the front side filter mounting portion 40, and the distance between the filter mounting portion 4 and the upward convex portion 5 other than the fixing portion relief portion 50a can be made uniform all around.

[0030] The front side protrusion 50 has a hole relief portion 50c for avoiding the wiring hole 75, so that the front side protrusion 50 is not discontinuous due to the wiring hole 75. The front side fixing portion 10a and the portion 50b other than the fixing portion clearance portion 50a and the hole clearance portion 50c of the front side protrusion 50 are provided in the same straight line. In the same straight line, both the same straight line and a slight deviation from the same straight line are included. The hole relief portion 50c is provided on the front side of the wiring hole 75. In other words, the hole relief portion 50c protrudes in an arc shape toward the front side plate 22 of the hood 2. The hole relief portion 50c is not limited to an arc shape, and may be a mountain shape, a trapezoid shape, or the like. According to this, hole relief portion 50c acts as a dike that stops liquid from flowing into wiring hole 75, and can prevent liquid flowing on upper surface 20a of hood top plate 20 from penetrating through wiring hole 75a into hood 2. For example, it can prevent cleaning liquid from penetrating into hood 2 when cleaning hood top plate 20. Furthermore, when wiring hole 75 is formed continuously from front filter mounting part 40 to hood top plate 20, front convex part 50 can be provided close to front filter mounting part 40. Depending on the size, shape, etc. of wiring hole 75, hole relief part 50c may not be formed in front convex part 50.

[0031] The main body 3 will be described in detail with reference to Fig. 10. Fig. 10 is an enlarged bottom view of the main body shown in Fig. 1. A mounting flange 8 is provided at the lower part of the peripheral plate 31 of the main body 3. The flange portion 8 has a fixed portion 12 to be fixed to the hood 2 . The fixed portion 12 is a screw hole into which the fastening member 11 such as a screw is screwed. The fixed portion 12 is not limited to this, and may be, for example, a hole through which the fastening member 11 passes. The main body 3 is attached to the hood top plate 20 by screwing the fastening member 11, which has passed through the fixing portion 10 of the hood top plate 20, into the fixed portion 12.

[0032] The flange portion 8 has a rectangular planar shape and is made up of a front flange portion 80 formed by bending the lower portion of the front side plate 32, a rear flange portion 81 formed by bending the lower portion of the rear side plate 33, a left flange portion 82 formed by bending the lower portion of the left side plate 34, and a right flange portion 83 formed by bending the lower portion of the right side plate 35. The front flange portion 80 protrudes further toward the front side than the front side plate 32. In other words, it faces outward. The rear flange portion 81 protrudes further toward the front side than the rear side plate 33. In other words, it faces inward. The left flange portion 82 protrudes further toward the right side than the left side plate 34. In other words, it faces inward. The right flange portion 83 protrudes further toward the left side than the right side plate 35. In other words, it faces inward.

[0033] The front flange portion 80 is longer than the dimensions of the left and right sides of the main body 3, and has a left protruding portion 80a that protrudes from the left side plate 34 and a right protruding portion 80b that protrudes from the right side plate 35 as shown in Figures 1 and 2, and the left and right protruding portions 80a, 80b are fixed to the hood top plate 20 with fastening members such as screws. This makes it possible to reinforce the hood top plate 20. The flange portions 80, 81, 82, 83 may be prepared separately from the plates 32, 33, 34, 35 and then secured to the lower portions of the plates 32, 33, 34, 35 by means of screws, bolts, welding or the like.

[0034] The fixed portion 12 has a plurality of front side fixed portions 12a provided on the front side flange portion 80, a plurality of left side fixed portions 12b provided on the left side flange portion 82, and a plurality of right side fixed portions 12c provided on the right side flange portion 83. With the front side fixed part 12a facing the front side fixing part 10a of the hood top plate 20 and the main body 3 in contact with the hood top plate 20, the fastening member 11 passing through the front side fixing part 10a is screwed into the front side fixed part 12a. With the left side fixed part 12b facing the left side fixing part 10b of the hood top plate 20 and the main body 3 in contact with the hood top plate 20, the fastening member 11 passing through the left side fixing part 10b is screwed into the left side fixed part 12b. With the right side fixed part 12c facing the right side fixing part 10c of the hood top plate 20 and the main body 3 in contact with the hood top plate 20, the fastening member 11 passing through the right side fixing part 10c is screwed into the right side fixed part 12c.

[0035] The installation of the main body will be described with reference to Fig. 11. Fig. 11 is a cross-sectional view taken along line E-E of the range hood shown in Fig. 2. The underside of the front flange portion 80 contacts the portion 50b other than the fixing portion clearance portion 50a and the hole clearance portion 50c of the front convex portion 50, i.e., a portion, and the underside of the rear flange portion 81 contacts the rear convex portion 51. The underside of the left flange portion 82 contacts the upper surface 20a of the hood top plate 20, and the underside of the right flange portion 83 contacts the upper surface 20a of the hood top plate 20. In this state, by screwing the fixing member 11 from each fixing portion 10a, 10b, 10c into each fixed portion 12a, 12b, 12c, the underside of the front side flange portion 80 is pressed against the front side convex portion 50, the underside of the rear side flange portion 81 is pressed against the rear side convex portion 51, and the undersides of the left side flange portion 82 and the right side flange portion 83 are pressed against the upper surface 20a of the hood top plate 20, thereby fixing and attaching the main body 3 to the hood top plate 20.

[0036] In this way, since the lower surfaces of the front and rear flange portions 80, 81 contact the front and rear protrusions 50, 51, respectively, the main body 3 can be attached to the hood top plate 20 in a well-balanced manner in the front and rear directions. Furthermore, since the contact areas between the front and rear flange portions 80, 81 and the front and rear convex portions 50, 51 are linear contacts with a narrow contact area, the force fixing the main body 3 to the hood top plate 20 or the weight of the main body 3 improves the adhesion between the contact area between the underside of the front flange portion 80 and the front convex portion 50 and between the underside of the rear flange portion 81 and the rear convex portion 51, eliminating gaps, and preventing liquid from entering through the contact areas between the hood top plate 20 and the front and rear sides of the main body 3.

[0037] In addition, since the underside of the left side flange portion 82 contacts the upper surface 20a of the hood top plate 20, and the underside of the right side flange portion 83 contacts the upper surface 20a of the hood top plate 20, each contact portion has a wide contact area, making the main body 3 stable and capable of being attached to the hood top plate 20 in a well-balanced manner in the left and right side directions. Furthermore, the left side flange portion 82 is positioned outboard of the left side protrusion portion 52, and the right side flange portion 83 is positioned outboard of the right side protrusion portion 53, so that when attaching the main body 3 to the hood top plate 20, it has a positioning function in the left and right side directions, making it easy to attach the main body 3.

[0038] Furthermore, by providing the fixing portion relief portion 50a in the front side protrusion 50, gaps are created between the periphery of the front side fixing portion 10a and the fixing portion relief portion 50a of the front side protrusion 50, and between the front side fixing portion 10a and the front side flange portion 80, so that the front side flange portion 80 can be firmly fixed by the pulling force generated by screwing the fastening member 11 into the front side fixed portion 12a. This allows the front side of the main body 3 to be firmly attached to the hood top plate 20. In addition, because the portion 50b of the front side protrusion 50 other than the fixing portion clearance portion 50a and the front side fixing portion 10a are arranged on the same straight line, the pulling force generated by screwing the fastening member 11 acts concentratedly on the portion of the front side flange 80 facing the portion 50b of the front side protrusion 50 other than the fixing portion clearance portion 50a of the front side protrusion 50, further improving the adhesion between the underside of the front side flange 80 and the front side protrusion 50. This makes it possible to eliminate any gap between the front side of the main body 3 and the hood top plate 20.

[0039] In the embodiment, the undersides of the front and rear flange portions 80, 81 are in contact with the front and rear convex portions 50, 51, and the undersides of the left and right flange portions 82, 83 are in contact with the hood top plate 20, but this is not limited to this, and the undersides of the front and rear flange portions 80, 81 may be in contact with the hood top plate 20 and the undersides of the left and right flange portions 82, 83 may be in contact with the left and right convex portions 52, 53, or the underside of one flange portion may be in contact with one convex portion, or the undersides of all flange portions may be in contact with convex portions.
