Description

  The present invention relates to a top plate for a drop-in type stove in which a stove body is disposed so as to drop into a stove opening established on a countertop.

  2. Description of the Related Art Conventionally, a top plate for a drop-in stove in which a main portion (top plate main body) of the top plate is configured by a highly decorative plate such as a glass plate is known (see, for example, Patent Document 1). In such a top plate, in order to protect the peripheral part of the top plate main body, a frame-like outer frame surrounding the top plate main body is provided, and the top plate is seated on the counter top in the outer frame.

Recently, in order to reduce the cost by omitting the outer frame, a top plate formed of a single thick plate made of metal (such as aluminum) has been developed. The top plate made of such a thick metal plate is heavy and high-class, but is heavy and inconvenient to handle.
JP 2001-193946 (paragraph 0004, FIG. 1 and FIG. 2)

  In view of the above, it is an object of the present invention to provide a drop-in top plate for a stove that has a good appearance and is light in weight and capable of obtaining a solid feeling similar to that of a metal plate top plate. Yes.

In order to solve the above-mentioned problem, the present invention is a top plate for a drop-in type stove that is arranged so that the stove body is dropped into a stove opening established in a counter top, A flat-plate-shaped top plate main body having a side plate portion formed by bending and having a lower surface as an open surface, the two sides intersecting at the corners of the four corners of the top plate main body Each of the side plates of the top plate is exposed, and a corner member is mounted on at least the front left and right corners of the four corners of the top plate. An inner bending flange that is bent inwardly at the lower edge is formed, and the corner member covers a side cover portion that covers an outer surface of a portion near the corner portion of the side plate portions of the two sides of the top plate that intersect at the corresponding corner portion ; Projects inwardly from the lower edge of the side cover, and is bent at the corners of the top plate And a lower surface cover portion that covers the lower surface of the flange, the lower surface cover portion, wherein the engaging portion engaged with the inner bent flange is formed.

  According to the above configuration, the main body of the top plate appears to be a thick metal plate having a thickness corresponding to the height dimension of the side plate portion even though it is made of sheet metal and is light, and a profound feeling can be obtained. A flat box-shaped top plate having a side plate portion can also be formed by drawing a sheet metal, but in this case, the radius of the bent portion of the side plate portion with respect to the top surface of the top plate and the radius of the four corners of the top plate are reduced. It must be taken large, giving a strong impression that it is a press-molded product, and a profound feeling is not created. On the other hand, in the present invention, since the side plate portion is formed by bending, the radius of the bent portion of the side plate portion with respect to the upper surface of the top plate can be reduced, and the corner portion can be formed into an angular shape, and the metal thick plate An impression close to that can be given.

  However, when the side plate portions are formed by bending, the side plate portions on the two sides that intersect at the corner portions are not continuous, and the edge of each side plate portion is exposed at the corner portions. When the edges of the side plate portions are exposed at the left and right corners on the front side that are visually noticeable, the appearance is impaired. However, according to the present invention, at least at the left and right corners on the front side, the edge of each side plate portion is covered and covered by the side cover portion of the corner member, so that the appearance is improved.

  Furthermore, if the upper surface cover portion is formed on the corner member so as to project inward from the upper edge of the side cover portion and cover the upper surface portion of the corresponding corner portion of the top plate, the boiled portion between the side cover portion and the side plate portion is formed. It is possible to prevent foreign matter such as spilled juice from entering, and even if a gap is formed between the side cover part and the side plate part, this gap is hidden by the top cover part and does not appear in the appearance, and the appearance is good. Kept.

  In addition, if an inwardly bent flange that is bent inward is formed at the lower edge of each side plate part of the top plate, a seal is attached between the top plate and the countertop by attaching a packing to the inwardly bent flange. Can be secured. In this case, a lower surface cover portion is formed on the corner member so as to project inward from the lower edge of the side cover portion and cover the lower surface of the inner bending flange at the corresponding corner of the top plate, and the inner bending flange is formed on the lower surface cover portion. It is desirable to form an engaging portion that engages with. When there is no lower surface cover part, there is a possibility that the lower edge of the side cover part is caught by something and the side cover part floats from the side plate part. On the other hand, if comprised as mentioned above, a side cover part will be latched by an internal bending flange by the engaging part via a lower surface cover part, and it can prevent that a side cover part floats from a side plate part.

  Further, when the lower surface cover portion is formed in this way, a packing may be attached to the lower surface of the inner bending flange over the lower surface of the lower surface cover portion, or the lower surface cover portion does not overlap the lower surface of the inner bending flange. You may stick packing like this. In the latter case, it is desirable to set the thickness of the lower surface cover portion and the material of the corner member so that the lower surface cover portion can ensure the sealing performance with the counter top at the location of the lower surface cover portion.

  FIG. 1 shows a state in which a drop-in stove is incorporated in the countertop 1 of the system kitchen. As shown in FIG. 2, the stove includes a box-shaped stove body 2 having an upper surface as an open surface. An outer bending flange 2 a is formed on the upper edge of the stove body 2, and the outer bending flange 2 a is placed at the opening edge of the stove opening 1 a in a state where the stove body 2 is dropped into the stove opening 1 a opened in the countertop 1. The stove body 2 is suspended from the countertop 1 by being hooked. And the top plate 3 covers the stove body 2 over the outer bending flange 2a from above. A packing 2b is attached to the peripheral edge of the outer bending flange 2a, and the outer bending flange 2a is seated on the counter top 1 via the packing 2b.

  As will be described in detail later, the top plate 3 includes a sheet metal top plate main body 4 formed in a flat box shape, and four corner members 5 mounted at four corners of the front, rear, left and right of the top plate main body 4. It consists of On the top surface of the top plate main body 4, three burner openings 4 a for opening three burners (not shown) arranged in the stove main body 2 are opened, and in the front central portion of the top surface of the top plate main body 4. The three operation elements 6 for the burner are arranged. The opening portions of the burner openings 4a of the top plate main body 4 are press-molded so as to rise upward, and the rising portion 4b prevents the spilled juice from flowing into the burner openings 4a and the rigidity of the top plate main body 4 I am trying to up. Although not shown, five virtues are placed on the top plate main body 4 so as to cover the swelled portion 4b from above for each burner opening 4a.

  As shown in FIGS. 2 and 3, the top plate main body 4 uses a sheet metal (for example, a stainless steel plate having a thickness of 0.8 mm), and includes a side plate portion 41 having a height of about 8 mm that is bent downward on each of the front, rear, left and right sides. It has a flat box shape. Here, when the top plate main body 4 is formed by drawing, the radius of the bent portion of the side plate portion 41 with respect to the upper surface of the top plate main body 4 and the radius of each corner of the four corners of the top plate main body 4 must be increased. It is not obtained, and the impression that the top plate main body 4 is a press-formed product is strongly given. Therefore, in the present embodiment, each side plate portion is formed so that the radius of the bent portion of each side plate portion 41 with respect to the upper surface of the top plate main body 4 is as small as possible and each corner portion of the top plate main body 4 is squared. 41 is formed by bending. Therefore, the top plate main body 4 has a feeling close to that of a thick metal plate, and a heavy feeling is obtained even though it is made of sheet metal and is lightweight. In addition, an inner bending flange 42 that is bent inward is formed at the lower edge of each side plate portion 41. A packing 43 is attached to the lower surface of the inner bending flange 42, and the top plate main body 4 is seated on the counter top 1 via the packing 43 outside the outer bending flange 2 a of the stove body 2. In addition, in order to improve the decorativeness of the top plate main body 4, it may be subjected to wrinkle processing, fluorine processing, or the like.

  By the way, when the side plate portion 41 is formed by bending as described above, it is formed at the four corners of the top plate main body 4 by the edges of the two side plate portions 41 and 41 of the top plate main body 4 that intersect here. A recessed portion 44 appears. If the recessed portion 44 is exposed, the appearance is impaired. Therefore, a resin corner member 5 is attached to each corner of the top plate main body 4, and the recessed portion 44 is blinded by the corner member 5 so that the appearance is not impaired. Yes. Although it is possible to weld the edges of the two side plate portions 41, 41 so that the recessed portions 44 are filled, it takes time and effort to finish the weld bead smoothly. Also in this case, if the corner member 5 is mounted, the weld bead is blinded, so that it is not necessary to finish the weld bead, which is advantageous. Further, visually conspicuous are the left and right corner recesses 44 on the front side of the top plate main body 4, and the left and right corner portions 5 on the rear side may be omitted.

  As shown in FIGS. 3 to 5, the corner member 5 has an L-shaped horizontal cross section that covers the outer surfaces of the side plate portions 41, 41 of the two sides of the top plate main body 4 that intersect at the corresponding corner portions, near the corner portions. Side cover portion 51, upper cover portion 52 projecting inward from the upper edge of side cover portion 51 and covering the upper surface portion of the corresponding corner of top plate main body 4, and inward from the lower edge of side cover portion 51 And a lower surface cover portion 53 that covers the lower surface of the inner bending flange 42 at the corresponding corner of the top plate main body 4. The lower surface cover 53 is divided into two corresponding to the inner bending flanges 42 and 42 of the side plates 41 and 41 on the two sides, and is engaged with the inner edge of each inner bending flange 42 at each half of the lower surface covering 53. A mating piece-like engaging portion 54 is integrally formed. Note that an engagement hole may be formed in the inner bending flange 42, and a protrusion-like engagement portion that fits into the engagement hole may be formed in the lower surface cover portion 53.

  According to the above configuration, the corner member 5 is locked to the inner bending flange 42 in the engaging portion 54 and attached to the corner portion of the top plate body 4. Then, the concave portions 44 at the corners are concealed by the side cover portion 51, and the appearance is kept good. Moreover, when wrinkle processing is performed on the top plate main body 4, wrinkles are easily lost at the corners, but this can also be prevented.

  The packing 43 is attached to the lower surface of the inner bending flange 42 over the lower surface of the lower surface cover portion 53. Here, the packing 43 is formed of a foamed elastic body such as chloroprene rubber sponge, and the portion of the packing 43 that overlaps the lower surface cover portion 53 is crushed by the weight of the top plate 3 and is flush with other portions. Therefore, when the top plate 3 is placed on the counter top 1, the packing 43 is in close contact with the counter top 1 over its entire length (the entire circumference of the top plate body 4), and a seal between the top plate 3 and the counter top 1 is provided. Sex is secured. Further, when a horizontal external force acts on the top plate 3 on the counter top 1, the lower surface cover portion 53 tends to be displaced with respect to the inner bending flange 42 by a frictional force acting between the counter top 1 and the packing 43. However, since the lower surface cover portion 53 is locked to the inner bending flange 42 by the engaging portion 54, the lower surface cover portion 53 is not displaced, and the side cover portion 51 is prevented from floating from the side plate portion 41 due to the displacement of the lower surface cover portion 53. Is done.

  In the first embodiment, the upper surface cover portion 52 is formed on the corner member 5. However, the corner member 5 is formed so as not to have the upper surface cover portion 52 as in the second embodiment shown in FIG. 6. It is also possible to do. In the second embodiment, a protrusion 51 a that enters the recessed portion 44 at the corner of the top plate body 4 is formed in the side cover portion 51 so that no gap is formed between the protruding portion 51 and the recessed portion 44. However, in this case, foreign matter such as simmered juice may enter between the side cover portion 51 and the side plate portion 41, and a gap is formed between the side cover portion 51 and the side plate portion 41. In this case, this gap becomes visible from above, and the appearance is impaired. On the other hand, if the upper surface cover portion 52 is formed as in the first embodiment, such a problem does not occur, which is advantageous.

  Further, in the second embodiment, the packing 43 is stuck to the lower surface of the inner bending flange 42 of the top plate main body 4 so as not to overlap the lower surface cover portion 53 of the corner member 5. In this case, the corner member 5 is formed of a relatively soft material having a hardness of about 60 to 80 HS, such as ABS resin, silicone resin, etc., and the thickness of the lower surface cover portion 53 is relatively small so that an appropriate compression allowance can be obtained. If it is formed thick (for example, 2 to 3 mm), it is possible to ensure the sealing performance with the counter top 1 at the place where the lower surface cover portion 53 is disposed by the lower surface cover portion 53 itself. In the second embodiment, the lower surface cover portion 53 is not divided into two, and is formed in an L shape in plan view extending across the inner bending flanges 42, 42 of the side plate portions 41, 41 on the two sides. Yes. In the case of the first embodiment as well, when the packing 43 is stuck so as not to overlap the lower surface cover portion 53, it is configured in the same manner, and the sealing performance can be secured by the lower surface cover portion 53 itself.

  7 and 8 show a third embodiment approximate to the first embodiment. The third embodiment is different from the first embodiment in that the engagement hole 45 is formed on the upper surface of the corner portion of the top plate main body 4 and the engagement hole 45 is formed on the lower surface of the upper surface cover portion 53 of the corner member 5. This is a point that a cylindrical projection 55 is formed to be engaged with. According to this, the corner member 5 is locked to the top plate main body 4 not only by the engaging portion 54 of the lower surface cover portion 53 but also by the protrusion 55 of the upper surface cover portion 53, and due to thermal deformation of the corner member 5. It is possible to prevent the upper surface cover portion 52 from floating from the upper surface of the top plate main body 4 due to warping. In addition, in order to make it easy to engage the protrusion 55 with the engagement hole 45, the protrusion 55 may be divided into a plurality of pieces in the circumferential direction.

  FIG. 9 shows a fourth embodiment that approximates the third embodiment. The fourth embodiment is different from the third embodiment in that a recess 46 is formed at the corner of the top plate main body 4 from the upper surface to the side plate 41. The size and depth of the recess 46 are equal to the size and thickness of the upper surface cover 52 and the side cover 51 of the corner member 5. Therefore, in a state where the corner member 5 is mounted on the corner portion of the top plate main body 4, the upper surface of the top plate main body 4 and the upper surface of the upper surface cover portion 52 of the corner member 5 are flush with each other, and the side plate of the top plate main body 4. The outer surface of the portion 41 and the outer surface of the side cover portion 51 of the corner member 5 are flush with each other.

  If the corner member 5 is locked to the top plate main body 4 by the projection 55 of the upper surface cover portion 53 as in the third and fourth embodiments, the engagement portion 54 of the lower surface cover portion 53 is not locked. The bottom cover 53 can be omitted. However, in this case, when the packing 43 protrudes to the outside of the inner bending flange 42 and comes into contact with the lower edge of the side cover part 51 or when something is caught on the lower edge of the side cover part 51, the side cover part 51 floats from the side plate portion 41 and impairs the appearance. On the other hand, if the engaging portion 54 of the lower surface cover portion 53 is locked to the inner bending flange 42, such a problem does not occur, which is advantageous.
