Description

  The present invention relates to a range hood, and more particularly to a reinforcing structure of a lower end portion of a main body constituting body such as a hood main body and a front plate constituting the range hood.

Conventionally, as shown in FIG. 4, the main body constituting body A <b> 1 constituting the waste gas capturing space such as the hood body 1 and the front plate is formed by pressing a metal flat plate, which is an edge thereof. The lower end edge is provided with an upward substantially U-shaped bent piece 7 inwardly at the lower end opening edge to increase the rigidity of the lower end portion. In this type of range hood, the corner portion cannot be bent along the shape of the hood. Therefore, after bending, it is necessary to attach another member 17 to the corner portion by welding or caulking to maintain strength. There was a lot of manufacturing processes, which caused the cost to rise.
In addition, in the case of bending upward into a substantially U-shape, the bent piece 7 is exposed greatly, deteriorating the appearance image and reducing the product value, and the edge of the metal plate is exposed sharply. Sometimes the user could be injured accidentally (the former).
Therefore, as shown in FIG. 5, an inward piece 8 is bent at an appropriate interval at the lower end of the main body structure A1, and an edge member 9 having a circular cross section is attached to the inward piece 8 by laser welding. The edge member 9 combines the reinforcement of the main body constituting body A1 and the makeup (see (the latter) Patent Document 1).
This gives the user a gentle image with a rounded edge rather than an image with a squared bottom edge, thereby enhancing the commercial value.

However, when the edge of the inwardly facing piece 8 that is bent from the main body constituting body A1 is exposed, this becomes a dangerous place at the time of cleaning, and when finishing is poor at the time of welding, a separate finishing process is required. This increases the manufacturing process and causes the manufacturing cost to rise.
Note that the prior art (the former) known to the applicant of the present application is not related to the literature known invention, and therefore the prior art document information is not disclosed in the present specification.
JP 2002-310477 A

  The present invention has been made in view of the above-mentioned conventional circumstances, and the intended process is to impart rigidity while giving the user a gentle image with roundness at the lower end of the main body constituting body such as a hood body and a front plate. In addition, it is intended to provide a range hood that is safe at the time of cleaning and inexpensive to manufacture.

The technical means taken in order to solve the above-mentioned problem is that a curl portion is integrally formed inward at a lower end portion of a main body constituting body such as a hood body or a front plate, and an end surface of an end portion of the curl portion is A range hood that is close to or abuts on the inner side of the lower end portion, or that the end portion of the curled portion is folded or wound along the inner side of the lower end portion so that the end portion is not exposed to the outside. Item 1).
And, it is effective to form the curled portion continuously at the corner of the main body constituting body (Claim 2).
In addition, the curled portion is formed integrally along the corner by bending the portion corresponding to the corner of the main body structure in the metal thin plate for forming the main body structure having a flat shape and curling at the end. (Claim 3).
Here, the main body component refers to a hood member that secures a waste gas capturing space.

  According to the above means, the curl portion inside the lower end portion of the main body constituting body such as the hood body and the front plate is made smaller than the upward substantially U-shaped bent piece disclosed in the prior art, and the edge having a circular cross section It gives the body structure a round design and rigidity that is almost similar to a range hood with welded members.

Since the present invention has a reinforcing structure in which a curl portion is integrally formed inward at the lower end portion of the main body constituting body such as the hood body and the front plate as described above, the upward substantially U-shaped bent piece is disposed inside. During cleaning, the edges of the bent pieces and the inwardly facing pieces are exposed, as in the case of bending inwardly or by bending the inwardly facing piece that attaches the edge member with a circular cross section to the lower end of the main body structure. It is safe without accidental injury.
In addition, it does not give the user a small and harsh feeling compared to the case where it is bent upward in a substantially U-shape, and the hood body and the hood body as in the case where the edge member having a circular cross section is welded to the inward piece. There is no fear that the edge member having a circular cross section is recognized as a separate body due to poor welding finish, and it is more elegant and smart, giving it a high-class feeling and increasing the commercial value.
In addition, the curled portion is provided at the end of the flat metal thin plate because it can be bent into the required shape while maintaining its curly cross-sectional shape even if it is bent by a bender or the like like the metal circular tube. The metal thin plate is bent as it is with a bender or the like, and is integrally molded while maintaining a predetermined cross-sectional shape without crushing the hollow portion along the corner of the main body constituting body. For this reason, after bending the main body structure, as in the case of bending upward into a generally U-shaped shape, another member is attached to the corner portion by welding or caulking to maintain strength, or the main body structure is bent. After that, since it is not necessary to weld an edge member having a circular cross section to the inwardly facing piece portion, it is possible to reduce the component parts and the manufacturing process, and to significantly reduce the material cost together with the manufacturing cost.

  Next, an embodiment of the range hood of the present invention will be described with reference to FIGS.

  As shown in FIG. 1, the range hood A has a blower unit 2 mounted on a top plate (not shown) of a flat and thin hood body 1 having an open lower surface, and communicates with the blower unit 2 and has an exhaust port ( (Not shown) is opened in the same top plate, and the grease filter 3 is provided so as to block the exhaust port from below in the hood body 1, and the grease filter 3 is concealed from the bottom by the rectifying plate 4 so as to be invisible. Illustrated is a type in which the blower unit 2 is concealed from the front by a curtain plate, and an illumination case 6 is provided on the rear end side of the hood body 1 over the entire length in the width direction, and the case 6 is illuminated downward. Is installed.

  And the curl part C is formed in the same body toward the lower end part of main body structural bodies A1, such as the hood body 1 and the front plate.

  This curled portion C is curled as is conventionally known. In the end processing, as shown in FIG. 2, the end portion is made horizontal or linear, and the end surface thereof is brought close to or in contact with the back surface of the main body constituting body A1. As shown to Fig.3 (a), an edge part is folded along the back surface of main body structural body A1. As shown in FIG.3 (b), an edge part is made to follow the back surface of main body structural body A1 like curly hair. And at least the ends are processed so as not to be exposed to the outside.

  At the corner of the main body constituting body A1, although not shown, the end of the metal flat plate for the main body constituting body is subjected to curling, and a portion corresponding to the corner of the main body constituting body on the metal flat plate is used using a bender or the like. By bending, the curled portion is integrally formed so as to be continuous along the corner of the main body constituting body.

In the present embodiment, a type in which the curling process is continuously performed on the three side surfaces of the hood body 1 excluding the back surface portion to which the lighting case 6 is attached is shown.
Of course, it is of course possible to form a curled portion at the lower end of the back surface.

  By the way, the range hood is not limited to the configuration described above, but has a type called a boot type that covers the front space with a front plate, a type called a flat type, and a current plate. The thin type, the island type, the open kitchen, etc., which include a hood member having a waste gas capturing space, regardless of its size, include all types of configurations.

  The range hood A configured as described above is a curled portion C integrally formed inward at the lower end portion of the main body constituting body A1 constituting the waste gas capturing space such as the hood body 1 and the front plate, and the main body structure. Gives the body A1 rigidity, gives a round and gentle image to the user, brings out a high-class feeling, is gentle on fingers during cleaning, simplifies the manufacturing process and reduces the materials used. Can be provided at low cost.
