Description

  The present invention relates to a top plate for a drop-in stove in which a stove body is disposed so as to drop into a stove opening established on a countertop, and more particularly to a top plate formed of a metal flat plate.

  Conventionally, a stove top plate is generally formed of a press-formed steel plate. In order to ensure rigidity, such a steel plate top plate is formed in a shape in which an outer peripheral edge portion, an opening edge portion of a burner opening, and the like are raised from other portions (for example, see Patent Document 1). As a result, the top plate is not flat, and a heavy feeling is not obtained, which gives the user a cheap feeling.

  Therefore, the applicant of the present application has previously proposed a stove top plate formed of a thick metal (for example, aluminum) flat plate according to Japanese Patent Application No. 2003-40523. In this case, since the flat plate itself constituting the top plate is highly rigid, it is not necessary to form a raised portion for increasing rigidity on the top plate, the top plate is flat, and it feels visually heavy. This gives a sense of quality.

However, since the top plate of the previous application has high thermal conductivity, the temperature of the front portion of the top plate becomes high due to heat conduction from the portion of the top plate near the heat source, and the top plate is thick. Since the heat capacity is large, it takes time until the temperature of the front portion of the top plate decreases after using the stove. Therefore, when a hand is touched to the front side part of a top plate, there is a possibility that the user may feel hot.
JP 2002-257358 A

  In view of the above points, the present invention provides an improved stove top for the stove according to the above-mentioned prior application, in which it is possible to avoid as much as possible the touching of the front part of the top plate to make the user feel hot. That is the issue.

  In order to solve the above-mentioned problems, the present invention is a top plate for a drop-in type stove that is arranged so as to drop the stove body into a stove opening established in a countertop, and is formed from a metal flat plate. It is characterized by comprising a main body and a resin protective body arranged along the front edge of the top plate main body.

  According to the present invention, the front side portion of the top plate that is easily touched by hand is constituted by the protective body, and it is possible to effectively prevent the hand from touching the top plate itself from the front side. The protective body is made of resin and has a lower thermal conductivity than that of a metal top plate. Therefore, even if the hand touches the protective body, it does not heat as much as the left. Moreover, even if the resin material (protector) is at the same temperature as the metal material (top plate main body), the degree of heat that is felt compared to the metal material is low. Therefore, it is possible to avoid as much as possible the touching the front side portion of the top plate to make the user feel hot.

  Note that, as a method of connecting the protector to the top plate main body, it is conceivable to screw the protector to the top plate main body from the front, but in this case, the screw appears on the appearance and the appearance is impaired. On the other hand, one engagement part of the male type and the female type is formed on the front edge of the top plate main body, and the other engagement part of the male type and the female type is formed on the protector, If it connects so that a protection body may be connected with a top-plate main body by fitting, a connection part (engagement part) will not appear in an external appearance, but a appearance will become favorable.

  Moreover, it is desirable that the protective body has a cover portion that projects rearward from the front edge of the top plate main body and overlaps with a portion near the front edge of the upper surface of the top plate main body. According to this, it can prevent more effectively that a hand touches the upper surface of the top plate main body by a cover part. Furthermore, even if a gap is formed between the end surface of the front edge of the main body of the top plate and the end surface of the protector facing the top plate, the gap is covered with the cover portion and does not appear in the appearance, and the appearance is kept good. . In addition, a step due to the rear edge of the cover part is formed on the top surface of the top plate, and when spilled, the simmered juice flows out from the top to the front of the top plate, and the front edge of the counter top There is also an effect that it is possible to prevent the dripping from being caused by this step.

  In addition, in order to be able to perform the operation of the heat source on the top plate, when forming an operation hole through which the operation shaft of the operation unit for the heat source disposed in the stove body is inserted in the portion near the front edge of the top plate main body, It is necessary to prevent the boiled spilled juice falling on the top plate from flowing into the stove body from the operation hole. Here, if the cover part is formed so as to overlap the formation area of the operation hole mainly composed of the top plate, the flow of boiled juice up to the formation area of the operation hole is suppressed by a step due to the rear edge of the cover part. It helps to prevent the boiled juice from flowing into the operation hole.

  In this case, it is necessary to form a through hole in the portion of the cover portion that overlaps with the formation portion of the operation hole, and to project the operation shaft onto the top plate through the operation hole and the through hole. Accordingly, when a large amount of boiled spill occurs and the boiled sap flows over the cover part over the step formed by the rear edge of the cover part, the boiled sap may flow into the operation hole from the through hole. Here, if a cylindrical projection that rises upward from the opening edge of the through hole is formed, the cylindrical projection functions as a bank portion surrounding the through hole, which can prevent the inflow of boiled juice from the through hole. It is.

  Furthermore, if a cylindrical fitting part that hangs down from the opening edge of the through hole and fits into the operation hole is formed in the cover part, the protector is positioned with respect to the top plate main body by this fitting part. It can be locked and is advantageous.

  In addition, in a drop-in stove, a seal member attached to the bottom surface of the top plate is used to prevent water on the counter top from entering the stove opening from the gap between the counter top and the top plate. Through the countertop. In this case, if the sealing member attached to the front edge of the lower surface of the top plate is secured to the top plate main body and the lower surface of the protector so as to straddle both the top plate main body and the protector, the top plate main body and the protection The connection with the body is advantageously ensured even on the lower surface by the sealing member.

  Further, when the top plate is seated on the counter top via the seal member as described above, the seal member attached to the front edge of the lower surface of the top plate is easily visible from the front, and the appearance is impaired. In this case, if the lower surface of the part of the protector located in front of the seal member attached to the front edge of the lower surface of the top plate is bulged below the upper surface of the seal member in a range not contacting the counter top The sealing member is difficult to see from the front, and the appearance can be kept good.

  FIG. 1 shows a drop-in type stove incorporated in the countertop 1 (see FIG. 3) of the system kitchen. The stove includes a box-shaped stove body 2 having an upper surface as an open surface. As shown in FIG. 3, an outer bending flange 2 a is formed at the upper edge of the stove body 2, and the outer bending flange 2 a is stowed 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 to the opening edge of the opening 1a. And the top plate 3 covers the stove body 2 over the outer bending flange 2a from above. Seal members 4F, 4S, and 4R are attached to the lower surface of the top plate 3 along the front edge, the left and right side edges, and the rear edge (see FIG. 2), and the opening of the stove opening 1a of the countertop 1 The top plate 3 is seated on the countertop 1 via seal members 4F, 4S, 4R outside the outer bending flange 2a of the stove body 2 that is hooked to the edge (see FIG. 3). This prevents water or the like on the countertop 1 from entering the stove opening 1a or the stove body 2. In this embodiment, the seal member is divided into four parts, that is, a seal member 4F on the front edge side, seal members 4S and 4S on the left and right side edges, and a seal member 4R on the rear edge side. Of course, it is possible to use an annular sealing member.

  The top plate 3 is disposed along the top plate main body 31 formed of a flat plate made of metal, for example, aluminum and having a relatively thick thickness (for example, thickness of 6 mm), and the front edge of the top plate main body 31. And a protective body 32 made of resin. The resin material forming the protective body 32 is preferably a heat-resistant resin such as PET-PBT having a rating according to UL94, which is a measure of flame retardancy, of V-0 or higher. The connection structure of the top plate main body 31 and the protection body 32 will be described in detail later.

  In the stove body 2, three burners 5 serving as heat sources are arranged at the left and right and the middle rear. As shown in FIG. 2, the top plate main body 31 is provided with three burner openings 311 that allow the burner 5 to face. Then, the five virtues 6 are placed on the top plate main body 31 so as to surround the respective burner openings 311. Further, three operation knobs 7 corresponding to the three burners 5 are arranged on the top plate 3 at the center near the front edge. As shown in FIG. 3, each operation knob 7 is connected to an operation shaft 8 a extending upward from a valve unit 8 for each burner 5, which is a heat source operation section provided in the stove body 2. In the portion near the front edge of the top plate main body 31, three operation holes 312 that are inserted through the operation shafts 8 a are formed corresponding to the three operation knobs 7 (see FIG. 3).

  By the way, since the top plate main body 31 has high thermal conductivity, the temperature of the front side of the top plate main body 31 becomes high due to heat conduction from the peripheral portion of the burner opening 311 when using the stove. Since it is thick and has a large heat capacity, it takes time for the temperature of the front portion of the top plate main body 31 to drop after the stove is used (after the burner 5 is extinguished). It is easy to accidentally touch the front part of the top plate 3 after using the stove, and touching the top plate main body 31 makes me feel hot. However, in this embodiment, since the protector 32 is disposed along the front edge of the top plate main body 31, it is possible to effectively prevent the hand from touching the top plate main body 31 itself from the front side. The protector 32 is made of resin and has a lower thermal conductivity than the top plate main body 31 and a lower degree of heat to be felt. Absent. Therefore, it is possible to avoid as much as possible the touching the front side portion of the top plate 3 to make the user feel hot.

  With reference to FIGS. 3 and 4, a male engagement portion 313 that protrudes forward is formed on the front edge of the top plate main body 31, and a cross section of the male engagement portion 313 is formed on the protection body 32. A female engaging portion 321 formed of a groove having a cross-sectional shape matching the shape is formed. Then, the protector 32 is connected to the top plate main body 31 by fitting the engaging portions 313 and 321 together. Here, an enormous portion 313a having a larger vertical width than the base end is formed at the distal end of the male engagement portion 313 so that the protector 32 is prevented from coming off forward. In this embodiment, the cross-sectional shape of the enormous portion 313a is a bowl shape, but may be another shape such as a square. Further, a female engagement portion may be formed on the front edge of the top plate main body 31, and a male engagement portion formed on the protection body 32 may be engaged therewith. In any case, by connecting the protector 32 to the top plate main body 31 by fitting the male and female engagement portions 313 and 321, the connecting portion between the protector 32 and the top plate main body 31 can be externally seen. Does not appear and looks good.

  By the way, when the enormous portion 313a is formed in the male engagement portion 313 as described above, it is difficult to assemble the protector 32 to the top plate main body 31 from the front side. Therefore, the protector 32 is slid from the top plate main body 31 in the lateral direction so that the female engagement portion 321 is engaged with the male engagement portion 313. Therefore, it is necessary to prevent the lateral displacement of the protection body 32 with respect to the top plate main body 31. In this case, a vertical screw hole is formed at an appropriate position of the male engagement portion 313, and the protection body 32 is screwed to the male engagement portion 313 from below using the screw hole, thereby protecting the protection body 32. However, this increases the number of parts and man-hours, which increases costs.

  Therefore, in the present embodiment, as shown in FIG. 3, the sealing member 4 </ b> F attached to the lower surface leading edge side of the top plate 3 extends over both the top plate main body 31 and the protection body 32 and protects the top plate main body 31 and the protection plate. It is fixed to the lower surface of the body 32 with an adhesive. According to this, the protector 32 is connected to the top plate main body 31 via the seal member 4F on the front edge side, and the lateral displacement of the protector 32 with respect to the top plate main body 31 can be prevented, and the cost can be reduced.

  In the present embodiment, the lower surface of the portion of the protector 32 positioned in front of the front edge side seal member 4F is bulged below the upper surface of the seal member 4F. According to this, the seal member 4F on the front edge side is blinded by the bulging portion 322 on the lower surface of the protection body 32, and the seal member 4F on the front edge side is difficult to see from the front, and the appearance is kept good. The bulging portion 322 is formed so as not to come into contact with the counter top 1 so that the seal member 4F on the front edge side is seated on the counter top 1 and the sealing performance is reliably ensured.

  In addition, since the appearance of the end of the seal member 4F on the front edge side is damaged when exposed in the lateral direction, the left and right side edge seal members 4S are attached so as to enter the lower surface of the end of the protective body 32 as shown in FIG. The end of the edge side seal member 4F is covered with the side edge side seal member 4S from the outside in the lateral direction.

  The protective body 32 is integrally formed with a cover portion 323 that protrudes rearward from the front edge of the top plate main body 31 and overlaps a portion near the front edge of the upper surface of the top plate main body 31. According to this, it is possible to more effectively prevent the cover portion 323 from touching the upper surface of the top plate main body 31 with the hand. Further, even if a gap is formed between the end surface of the front edge of the top plate main body 31 and the end surface of the protective body 32 facing the top plate main body 31, the gap is covered with the cover portion 323 and does not appear in appearance, and the appearance is good. Kept. In addition, when boiled spilled, the boiled spilled juice flows out from the top 3 to the front of the top 3, and the boiled spilled soup drops from the front edge of the countertop 1 and soils the floor. become. However, when the cover portion 323 is formed as described above, a step 324 is formed on the upper surface of the top plate 3 by the rear edge of the cover portion 323, and this step 324 indicates that the simmered juice flows to the front of the top plate 3. It is possible to prevent the spilled juice from dripping on the floor.

  Furthermore, in the present embodiment, the cover portion 323 is formed so as to overlap the above-described formation region of the operation hole 312 of the top plate main body 31, and the through-hole 325 is formed in the portion of the cover portion 323 that overlaps the formation region of the operation hole 312. The operation shaft 8a is protruded on the top plate 3 through the operation hole 312 and the through hole 325. When the cover portion 323 is formed so as to overlap with the formation region of the operation hole 312 in this way, it is possible to suppress the boiled juice from flowing to the formation region of the operation hole 312 with the step 324 due to the rear edge of the cover portion 323. Therefore, it is not necessary to separately attach a packing for preventing the inflow of the boiled juice into the operation hole 312 and the cost can be reduced.

  In addition, when a large amount of spilled liquid is produced and the spilled juice flows over the step 324 due to the rear edge of the cover part 323 and flows on the cover part 323, the boiled liquid is boiled in the stove body 2 from the through hole 325 through the operation hole 312. Spilled juice may flow in. Therefore, in the present embodiment, a cylindrical protrusion 326 that rises upward from the opening edge of the through hole 325 is formed on the cover portion 323. According to this, the cylindrical protrusion 326 functions as a bank part surrounding the through hole 325, and the inflow of the simmered juice from the through hole 325 can be reliably prevented.

  Further, the cover portion 323 is formed with a cylindrical fitting portion 327 that hangs down from the opening edge of the through hole 325 and fits into the operation hole 312. Therefore, the protection body 32 is positioned and locked with respect to the top plate main body 31 also by the fitting portion 327, and the connection strength of the protection body 32 to the top plate main body 31 is increased.

  By the way, a sign such as a logo mark may be attached on the top plate 3, but when the top plate 3 is composed only of a metal flat plate, the sign may be imprinted on the upper surface of the flat plate by embossing. Conceivable. However, in this case, the sign becomes a dent, and dirt easily accumulates there, which impairs the appearance. Moreover, although it is possible to stick the film which printed the label | marker on the upper surface of a flat plate, in this, a film may peel off during cleaning, and it is unpreferable. Therefore, in this embodiment, a marker 328 having a convex cross section is integrally formed on the upper surface of the protector 32. This is advantageous because dirt does not easily accumulate on the sign 328 and the sign does not peel off. Further, since the protector 32 is made of resin, there is an advantage that various color variations are possible by coloring the resin.

  In the above embodiment, the cover portion 323 is formed so as to overlap the region where the operation hole 312 of the top plate main body 31 is formed, but the cover portion 323 may be formed so as to avoid the region where the operation hole 312 is formed. In addition, the cover portion 323 can be omitted. Further, the sealing member 4F on the front edge side can be fixed to one lower surface of the top plate main body 31 and the protection body 32 without straddling both the top plate main body 31 and the protection body 32.

  In the above embodiment, the protector 32 is slid from the top plate main body 31 in the lateral direction, and the female engagement portion 321 is engaged with the male engagement portion 313. However, the present invention is not limited to this. Absent. For example, as in the second embodiment shown in FIG. 5, a male engagement portion 313 is formed on the front edge of the top plate main body 31 so as not to reach the lateral end thereof, and the protective member 32 has a bag hole shape. It is also possible to engage the female engagement portion 321 with the male engagement portion 313 by forming the female engagement portion 321 and pushing the protector 32 into the top plate main body 31 from the front. . In this case, the male engagement portion 313 is not exposed in the lateral direction, and the appearance is improved.

  However, in this case, in order to allow the protector 32 to be pushed in from the front, the vertical width of the enormous portion 313a at the tip of the male engaging portion 313 is made relatively small or the enormous portion 313a is omitted. It is necessary, and the protector 32 is easily removed forward. In this case, as in the above embodiment, the sealing member on the front edge side is fixed to the lower surface of the top plate main body 31 and the protection body 32 so as to straddle both the top plate main body 31 and the protection body 32, or the cover portion. By forming a fitting portion for the operation hole in 323, it is possible to prevent the protector 32 from coming forward from the top plate main body 31. It is also possible to prevent the protector 32 from coming off by screwing the protector 32 to the male engagement portion 313 from below.
