Description

  The present invention relates to a range hood and a method for manufacturing the range hood.

  Conventionally, a range hood having a substantially conical hood portion has been proposed which is connected to a duct cover at the upper part and gradually spreads downward from above to collect air containing oil, steam, etc. (For example, Patent Document 1). Such a range hood does not have a corner portion in the hood portion, and a curved portion formed only by a curve having a small curvature is a visual main element, and therefore exhibits high designability when placed in a dining kitchen or the like.

Japanese Patent Laid-Open No. 08-247518

  However, in such a range hood, a joint line appears at the boundary between the hood part and the duct cover, there is no sense of unity as a whole, and the beauty of the curve expressed in the hood part is reduced. . In order to solve this problem, it is conceivable to put a band-shaped decorative member between the hood part and the duct cover in order to smoothly connect the hood part to the duct cover. In order to make a member, there is a problem that an expensive metal mold is required or a gap is generated between the hood part and the decorative member or between the duct cover and the decorative member unless the dimensions are accurately obtained.

  Therefore, the present invention provides a range hood having a high design property and a method for manufacturing the same, in which a decorative member can be produced at a low cost, and the decorative member is attached in close contact with the hood portion so that a gap is hardly generated.

In order to solve the above problems, a hood portion having an opening for sucking air, a duct cover provided on the hood portion, covering the duct, and less rigid than the hood portion, the joint between the duct cover and the hood portion The cut surface shape of the duct cover by the horizontal plane in the vicinity of the joint when installed is a first curved portion, and the cut surface shape of the hood portion by the horizontal plane when installed is The first curved portion has a second curved portion having a curvature smaller than the curvature of the first curved portion, and has a curvature that decreases from the joint of the hood portion toward the opening, and the end portion of the belt portion intersects the vertical plane. A range hood is provided in which the first angle formed by the intersecting line and the vertical direction is larger than the second angle formed by the second intersecting line where the central portion of the belt portion intersects the vertical plane and the vertical direction.
According to this, by attaching to the hood part in a state where the end of the band-shaped decorative member (band part) having low rigidity is spread, the center part of the band part rises conversely, that is, the band part is the hood. By attaching to the part with the first angle larger than the second angle, the lower end of the belt part is pressed against the hood part to be in close contact with the hood part, and a range hood with high design that is unlikely to cause a gap can be provided. . Moreover, since a cheap flat metal plate can be used for a belt | band | zone part, even in the range hood which requires fireproof performance, the range hood which gave the makeup which does not cost can be provided.

Further, the width of the end portion may be wider than the width of the central portion.
According to this, since the width of the end portion of the band portion is wider than the width of the central portion, it becomes easy to make the end portion widened, and from the end portion at the lower end of the band portion to the central portion. Since the amount of change per unit length from the first angle to the second angle is reduced by increasing the length of, the gap is less likely to occur.

In order to solve the above problems, a curved hood portion having an opening for sucking air, a curved duct cover provided on the hood portion and covering the duct, and having a lower rigidity than the hood portion, the duct cover and the hood In the manufacturing method of the range hood provided with a band part covering the joint of the part, the band near the joint of the hood part while pressing the end part in the longitudinal direction of the band part toward the opening having a smaller curvature than the joint. A method of manufacturing a range hood is provided in which the belt portion is connected to the hood portion and the belt portion is attached to the hood portion in a state where the belt portion is wound in a substantially horizontal direction and the belt portion is pressed down. .
According to this, the end part of the band part is widened by wrapping and connecting the band-shaped decorative member (band part) having a low rigidity to the hood part around the joint while pressing the end part in the opening direction. In the state where the center part of the belt part stands up and is attached to the hood part, and the lower end of the belt part is pressed against the hood part and is in close contact with the hood part. A manufacturing method can be provided. Moreover, since an inexpensive flat metal plate can be used for the band part, even in a range hood that is required to have fireproof performance, it is possible to provide a method for manufacturing a range hood with makeup that does not cost much.

  As described above, according to the present invention, a decorative hood with a high design property that can produce a decorative member at a low cost and is less likely to cause a gap due to the decorative member being attached in close contact with the hood portion and its manufacture. A method can be provided.

Embodiments according to the present invention will be described below with reference to the drawings.
<First Example>
The range hood 100 in a present Example is demonstrated with reference to FIG. 1 thru | or FIG. The range hood 100 is an apparatus for collecting air containing oil smoke rising from a cooker or the like disposed below the range hood 100 and exhausting it outside the house via the duct DU. The range hood 100 is provided on the hood 10 having the opening 16 for sucking air, the pipe-shaped decorative member 20 attached to the lower end 11 of the hood 10, and the hood 10 and covers the duct DU. The duct cover 30, the fan case 40 provided inside the hood portion 10, and the fan case provided below the fan case 40 and collecting air collected by the lower end portion 11 of the hood portion 10 via the air passage 44. 40, an inner surface panel 50 leading to 40, and a band portion 60 covering the joint 31 of the duct cover 30 and the hood portion 10.

  The hood portion 10 has a substantially truncated cone shape except for the back side where the flat back plate 18 is provided. More precisely, the surface profile of the hood portion 10 extends from the arc shape CL to the back plate 18 on both sides on the back side and the curved surface on the side surface of the truncated cone having a semicircular arc shape CL on the front side. It is comprised from the plane which has the linear form ST provided. The hood portion 10 has an arc shape CL having the largest radius at the lower end portion 11 forming the opening portion 16, and an arc shape CL having the smallest radius at the upper end portion 111 closest to the duct cover 30.

  That is, the hood portion 10 has an arc shape CL having the smallest curvature at the lower end portion 11 and has an arc shape CL having the largest curvature at the upper end portion 111. These radii / curvatures vary linearly between the upper end 111 and the lower end 11. In such a hood part 10, when the range hood 100 is installed, the cut surface shape of the hood part 10 cut by the horizontal plane is a hood part curved part 17 (second curved part) having a substantially arc shape CL on the front side. )including. The hood portion bending portion 17 has a curvature smaller than the curvature of the duct cover bending portion 32 of the duct cover 30 described later, and has a curvature that decreases from the upper end portion 111 of the hood portion 10 toward the opening portion 16.

  The hood portion 10 will be described in detail with reference to FIGS. The hood portion 10 is formed by pressing or laser processing a flat plate having an outer shape in which rectangular end portions 15 are extended on both sides of the developed shape of the side surface of the truncated cone, and the front side is curved in a generally arc shape CL. A frustoconical shape having a portion 17 is formed in a shape in which a rectangular plane is extended to both end portions 15. When installed, in this embodiment, the upper end 111 on the front side is formed to be slightly higher, but the upper end 111 of the hood 10 is generally horizontal as a whole. The lower end portion 11 of the hood portion 10 is formed so that the front side is slightly higher as a whole. The lower end portion 11 has a substantially semicircular arc shape CL on the front side and linear STs on both sides thereof, ie, both end portions 15 on the back side. That is, the lower end portion 11 has a linear shape ST at both end portions 15 and a generally arc shape CL between both end portions 15.

  The lower end portion 11 has an engagement piece 12, an engagement claw 13, and a detent engagement portion 14 for attaching a decorative member 20 described later. The anti-rotation engaging portions 14 are provided one by one at the end on the most back side of both end portions 15 of the linear ST, and are fitted with holes that are anti-rotation engaged portions 22 of the decorative member 20 described later. The anti-rotation engaging portion 14 is a rectangular flat plate extending in a convex shape from the lower end portion 11, but is not limited thereto, and may have any shape as long as the anti-rotation engaging portion 22 is fitted to the anti-rotation engaged portion 22. .

  A plurality of the engagement pieces 12 and the engagement claws 13 are appropriately provided on the lower end portion 11 having the arc shape CL. Even if there are too many engagement pieces 12 and engagement claws 13, workability is deteriorated, and at least, a gap is likely to be generated between the lower end portion 11 and the decorative member 20. In the present embodiment, the engagement pieces 12 and the engagement claws 13 are alternately provided, but the present invention is not limited to this, and the engagement pieces 12 may be provided between the engagement claws 13. By providing the engaging piece 12 between the engaging claws 13, the decorative member 20 can be easily attached to the lower end portion 11 without the decorative member 20 protruding from the lower end portion 11. The engaging pieces 12 are fitted into the slits 21 of the decorative member 20 and are engaged with each other. The engagement piece 12 is a rectangular flat plate extending from the lower end portion 11, but is not limited thereto, and may have any shape that can be fitted to the slit 21 and slidable to some extent while being fitted.

  The engaging claw 13 has a claw portion 131 that engages with the slit 21 and is engaged with the inner surface of the pipe-shaped decorative member 20. The engaging claw 13 is a flat plate extending from the lower end portion 11 and having a claw portion 131 at the tip. Thus, by providing the engaging piece 12 that only fits into the slit 21 of the decorative member 20 and does not engage with the decorative member 20 together with the engaging claw 13 that engages, the decorative member 20 is positioned with the lower end portion 11. There is provided a range hood 100 that can easily attach the pipe-shaped decorative member 20 to the lower end portion 11 of the hood portion 10 with little friction without slipping out of the lower end portion 11 and improving workability in manufacturing. it can.

  Further, the decorative member 20 will be described in detail with reference to FIG. The decorative member 20 is a hollow pipe-shaped member that is attached to the lower end portion 11 of the hood portion 10 and has substantially the same shape as the outer shape of the lower end portion 11. In other words, the decorative member 20 has a linear shape ST at portions corresponding to both end portions 15 of the hood portion 10 and a generally arc shape CL between portions corresponding to both end portions 15. Moreover, the decoration member 20 has the slit 21 which is a some slit-shaped hole so that it may adapt to the position of the engagement piece 12 and the engagement nail | claw 13, and they may fit.

  The slit 21 is not opened directly upward in a plan view, conforms to the inclination of the hood portion 10, and cannot be seen from a diagonally downward direction or a horizontal direction that becomes a normal line of sight when installed. Similarly, the gap formed between the hood portion 10 and the pipe-shaped decorative member 20 is inclined slightly inward from the top so as not to be seen. The slit width of the slit 21 is slightly larger than the plate thickness so that the engagement piece 12 and the engagement claw 13 are fitted. The slit length of the slit 21 into which the engagement piece 12 is fitted is longer than the length of the rectangular engagement piece 12 by a deviation width, and the slit length of the slit 21 into which the engagement claw 13 is fitted is It is slightly larger than the length of the claw portion 131 so that the portion 131 fits.

  Further, the decorative member 20 is adapted to the position of the anti-rotation engaging portion 14 at the end closest to the back plate 18, and the slit-like anti-rotation engaged portion 22 corresponds to the both end portions 15 so as to be fitted. Have. The slit width of the anti-rotation engaged portion 22 is slightly larger than the thickness of the anti-rotation engaging portion 14 so that the anti-rotation engaging portion 14 is fitted, and the slit length is the anti-rotation engaging portion 14 of the anti-rotation engaging portion 14. It is substantially the same as the length of the rectangular anti-rotation engaging portion 14 so that it does not shift when fitted into the engaging portion 22. The decorative member 20 is made of an elastic member and is usually made of a pipe made of a metal such as stainless steel having a plate thickness of 1 mm or less, but is not limited thereto. In this way, when the anti-rotation engaging portion 14 is fitted into the anti-rotation engaged portion 22, the decorative member 20 does not move with respect to the lower end portion 11, and the pipe-shaped decorative member 20 becomes the hood portion. Thus, it is possible to provide the range hood 100 that does not easily fall off from the lower end 11 of the ten.

  Further, when the lower end portion 11 has only a linear shape or only an arc shape, when the decorative member 20 is slid, it is necessary to slide while lifting the end portion provided with the anti-rotation engaging portion 14. Since there is a portion corresponding to both end portions 15 of the linear shape ST extending in the tangential direction from the end of the arc shape CL, the linear ST portion of the lower end portion 11 and the linear ST portion of the decorative member 20 are shifted laterally. This eliminates the need for lifting. Therefore, when attaching the decorative member 20 to the lower end portion 11, the decorative claw 13 that fits the slit 21 provided in the arcuate CL portion is fitted and the decorative member 20 is slid, and then the end of the decorative member 20 is moved. The decorative member 20 can be easily attached to the lower end portion 11 because the anti-rotation engaging portion 14 provided at the portion of the linear shape ST may be fitted to the anti-rotation engaged portion 22 by lifting.

  The duct cover 30 will be described in detail with reference to FIG. The duct cover 30 is provided on the hood part 10 and covers the duct DU. The lower portion of the duct cover 30 is fitted inside the upper end portion 111 of the hood portion 10, and the duct cover curved portion 32 having a substantially semicircular arc shape CL on the front side and the vicinity of both sides thereof, that is, the back side, has a straight ST. Have. That is, when the range hood 100 is installed, the cut surface shape of the duct cover 30 cut along the horizontal plane includes the duct cover curved portion 32 (first curved portion) having a substantially arc shape CL on the front side. The duct cover curved portion 32 has the same curvature from the bottom to the top, and has a substantially cylindrical shape. The duct cover bending portion 32 has a larger curvature than the curvature of the hood portion bending portion 17 of the hood portion 10.

  In this embodiment, since the lower portion of the duct cover 30 is fitted inside the upper end portion 111 of the hood portion 10, the joint 31 between the duct cover 30 and the hood portion 10 in appearance is connected to the upper end portion 111 of the hood portion 10. Match. However, the joint 31 of the duct cover 30 and the hood portion 10 in appearance coincides with the lower end of the duct cover 30 when the lower portion of the duct cover 30 is in contact with the outside of the upper end portion 111 of the hood portion 10. Since the duct cover 30 has a substantially cylindrical shape on the front side, the duct cover 30 also has a duct cover curved portion 32 in the vicinity of the joint 31.

  The fan case 40 is a device that is provided inside the hood portion 10 and generates a flow of air that is sucked from the opening 16 of the hood portion 10 and exhausted to the duct DU. In the present embodiment, it is provided inside the hood part 10, but is not limited to this, and may be provided near the duct DU above the hood part 10, for example. The fan case 40 includes therein a fan 41 that generates an air flow, a fan motor 42 that rotationally drives the fan 41, an opening 45 that faces the air passage 44 and sucks air, and a duct that exhausts air to the duct DU. And a connection unit 43. In the present embodiment, the fan 41 is a sirocco fan having a high static pressure, but is not limited thereto, and may be an axial fan, for example.

  The inner surface panel 50 guides the air collected by the opening 16 of the hood 10 to the fan case 40 via the air passage 44 that is an opening at the center. Below the inner panel 50 is provided a rectifying plate 51 that increases the flow velocity of the air near the decorative member 20 at the lower end of the hood 10 to increase the collection efficiency. A switch 52 for turning the range hood 100 on and off is provided.

  The belt 60 will be described in detail with reference to FIGS. The belt part 60 is a belt-like or elongated member for covering the joint 31 between the duct cover 30 and the hood part 10. In the present embodiment, the width WE of the end portion 61 of the band portion 60 is wider than the width WC of the central portion 62. At the upper part of the end part 61, there is provided an attachment part 63 for bending and attaching to the upper part of the hood part 10, and at the side part of the end part 61, a rear attachment part 631 for bending and attaching to the rear face of the hood part 10. The band portion 60 is made of a member that is softer than the hood portion 10 because it is thinner than the plate thickness used for the hood portion 10, that is, is less rigid than the hood portion 10. For example, the band portion 60 is produced by extracting from a flat plate made of stainless steel having a plate thickness of 0.3 to 0.8 mm by pressing or laser processing.

  It is preferable that the upper end 64 of the band portion 60 is in contact with the duct cover curved portion 32 having the arc shape CL of the duct cover 30 or the back side portion having the linear shape ST and there is no gap. The lower end 65 of the band portion 60 is pressed against and closely contacts the hood portion curved portion 17 having the arc shape CL and the both end portions 15 having the linear shape ST of the hood portion 10, and between the lower end 65 and the hood portion 10. In the state where there is no gap, the soft belt portion 60 is attached so as to be wound around the hood portion 10.

  Thus, the angle of the edge part 61 and the center part 62 of the band part 60 has the following characteristics in the attached state by attaching the band part 60 to the hood part 10. That is, the first intersection line L1 (for example, the first crossing line BB with the BB cross section in FIG. 1) is shown in FIG. The first angle A1 formed by the vertical direction is the second intersection line (for example, the AA cross section) where the central portion 62 of the belt portion 60 intersects the vertical plane (for example, the AA cross section in FIG. 1). The second intersection line L2 is larger than the second angle A2 formed by the vertical direction and the second intersection line L2 is shown in FIG.

  By having such a feature, the end portion 61 of the band portion 60 which is a band-shaped decorative member that is soft and has low rigidity is attached to the hood portion 10 in a state of being spread in the horizontal direction. The central portion 62 rises (becomes close to the vertical direction), that is, the belt portion 60 is attached to the hood portion 10 with the first angle A1 being larger than the second angle A2, so that the lower end 65 of the belt portion 60 is the hood portion. Thus, the range hood 100 with high design properties can be provided that is pressed and pressed into close contact with each other and hardly causes a gap.

  In addition, since the belt portion 60 can be an inexpensive flat metal plate, the belt portion 60 is used for drawing processing even in a range hood that requires many parts made of metal because fire resistance is required. It is possible to provide a range hood 100 that can be manufactured without a high-priced mold and has a makeup that does not incur costs such as mold manufacturing costs. Further, since the width WE of the end portion 61 of the band portion 60 is wider than the width WC of the central portion 62, it is easy to apply a force to the end portion 61, and the end portion 61 can be easily expanded. At the same time, since the length from the end 61 to the center 62 at the lower end 65 of the band 60 is increased, the amount of change per unit length from the first angle A1 to the second angle A2 is reduced (first). Since the angle gradually changes more gradually from the first angle A1 to the second angle A2, a gap is less likely to occur.

  With reference to FIG. 11 thru | or FIG. 14, the method to attach the belt | band | zone part 60 to the hood part 10 is demonstrated. First, as shown in FIG. 11, one end 61 of the band portion 60 is aligned and screwed so that the attachment portion 63 contacts the upper surface of the hood portion 10. In this case, the upper end 64 of the band part 60 is above the upper end part 111 of the hood part 10 that becomes the joint 31 of the hood part 10 and the duct cover 30, that is, the joint 31 is covered with the band part 60. Align. And if it can align and screw, the back surface attaching part 631 of the one edge part 61 will be attached to the back plate 18 by screwing.

  Next, since the belt portion 60 is made of a soft material with small rigidity, the other attachment portion 63 is the upper surface of the hood portion 10 while pressing the other end portion 61 downward (in the direction of the opening portion 16). The band 60 is wound around the joint 31 and screwed with it so that it is in contact with the belt. And as shown in FIG. 12, the back surface attaching part 631 of the other edge part 61 is attached to the back plate 18 by screwing. That is, when the longitudinal direction of the belt portion 60 is installed in the vicinity of the joint 31 of the hood portion 10 while pressing the end portion 61 in the longitudinal direction of the belt portion 60 toward the opening 16 having a smaller curvature than the joint 31. The belt part 60 is attached to the hood part 10.

  Next, as shown in FIG. 13, both the attachment parts 63 of the band part 60 and the upper part of the hood part 10 are firmly connected via the attachment fitting 19 with the band part 60 pressed downward. After the belt portion 60 is firmly connected to the upper portion of the hood portion 10, the duct cover 30 is attached so as to be fitted inside the upper end 64 of the belt portion 60 as shown in FIG. 14.

  In this way, the band-shaped decorative member (band part 60) having a small rigidity is wound and connected to the hood part 10 around the joint 31 while pressing the end part 61 in the direction of the opening 16 to thereby connect the band part 60. The end portion 61 is spread and the central portion 62 of the belt portion 60 rises (relatively close to the vertical direction) and is attached to the hood portion 10, and the lower end 65 of the belt portion 60 is the hood portion. The manufacturing method of the range hood with the high design property which is made into the state pressed and pressed to 10 and it is hard to produce a clearance gap can be provided. Moreover, since the belt part 60 can use an inexpensive flat metal plate, even in a range hood that requires fireproof performance, a method for manufacturing a range hood with makeup that does not require cost such as mold production costs is provided. can do. In the present embodiment, the attachment portion 63 of one end 61 in the band portion 60, the rear attachment portion 631 of the one end portion 61, the attachment portion 63 of the other end portion 61, and the rear attachment portion of the other end portion 61. Although it has been described that the belt portion 60 is attached to the hood portion 10 in the order of 631, the present invention is not limited to this. For example, the attachment portion 63 of one end portion 61 of the belt portion 60, the attachment portion 63 of the other end portion 61, You may attach in order of the back surface attachment part 631 of the edge part 61 of this, and the back surface attachment part 631 of the other edge part 61.
