Description

  The present invention relates to a gas stove mat, and more particularly to a gas stove mat mounted around a gas burner of a gas stove to cover a surface of a top plate.

  The gas stove is generally configured such that a gas burner is provided in an opening formed in a top plate, and a gas burner for supporting a pot or the like on the gas burner is arranged around the gas burner. In addition, usually, around the gas burner, a burner ring for closing the opening of the top plate is mounted. In recent years, a top plate having a flat surface has been often used for easy maintenance.

  By the way, when cooking on a gas stove, food scraps, oil, and the like are scattered from a frying pan, and liquids such as boiled juice and boiled juice are spilled out of a pan, often contaminating the surface of a top plate around a gas burner. Accordingly, a gas stove mat has been provided which covers the periphery of the gas burner and prevents dirt from adhering to the top plate. Such a conventional gas stove mat is described in, for example, JP-A-2006-40513 (Patent Document 1) and JP-A-2015-7513 (Patent Document 2).

  7A and 7B show a conventional gas stove mat described in Patent Literature 1, in which FIG. 7A is a schematic perspective view showing a use state, and FIG. 7B is a cross-sectional view showing a use state. As shown in FIG. 7, in the gas stove 20, for example, a gas burner 23 is arranged in an opening 22 formed in a top plate 21, and a burner ring 24 that covers the opening of the top plate 21 is arranged around the gas burner 23. Then, a goto 25 for placing a pot or the like is removably attached so as to surround the outer periphery of the burner ring 24. The gas stove mat 30 is disposed between the top plate 21 and the gorge 25 so as to cover the surface of the top plate 21 outside the burner ring 24. Therefore, the hole diameter of the opening 30 a formed in the center of the conventional gas stove mat 30 is set to be larger than the outer diameter R of the burner ring 24.

  In the gas stove mat described in Patent Literature 2, one or more opening auxiliary lines are formed concentrically with the opening at the center, and the opening auxiliary line corresponding to the outer diameter of the burner ring of the gas stove to be applied is used by the user. By cutting off, the hole diameter of the opening portion can be made to correspond to the outer diameters of a plurality of types of burner rings with one kind of product. The gas stove mat of Patent Document 2 is also set such that the hole diameter of the opening is larger than the outer diameter of the burner ring.

The conventional gas stove mat 30 described in Patent Literature 1 or Patent Literature 2 is designed to cover the surface of the top plate 21 outside the burner ring 24 protruding from the top plate 21. That is, conventionally, the surface of the top plate 21 is not covered in a region between the burner ring 24 and the gas stove mat 30. For this reason, solids such as food scraps scattered during cooking or liquids such as oil or spilled boiled liquid adhere to the top plate 21 between the burner ring 24 and the gas stove mat 30, or the top plate 21 and the gas stove There is a problem that they may be contaminated by invading the mat 30 or the like.

  As shown in FIG. 8, when the tip 25 a of the portion supporting the bottom of the pot or the like in the gotoku 25 is located near or inside the outer periphery of the burner ring 24, the liquid spilled out of the pot or the like. L reaches the tip portion 25a through the virtue 25 as indicated by the arrow, from which it falls down toward the burner ring 24, and contaminates the surface of the burner ring 24. Further, when the burner ring 24 has a structure that can be attached to and detached from the top plate 21, the dropped liquid L enters the inside of the burner ring 24 through the gap G between the burner ring 24 and the top plate 21. This causes a problem that dirt sticks to the inside of the ring 24 and sticks.

  Further, the conventional gas stove mats described in Patent Literature 1 and Patent Literature 2 are formed to have a substantially flat shape in accordance with the surface shape of the top plate, and a liquid such as broth spilled out of a pan during cooking is used. Since the blocking function is not high, there is also a problem that the spilled liquid is likely to flow out around the gas stove mat.

  The present invention has been made in order to solve the above-described problems, and a top plate and a burner ring around a burner ring are provided by solids such as food waste scattered at the time of cooking or liquid such as oil or broth spilled.

  1A and 1B show an example of a gas stove mat according to an embodiment of the present invention, wherein FIG. 1A is a front view and FIG. 1B is a plan view. FIG. 2 is a sectional view taken along line AA of FIG. FIG. 3 is a cross-sectional view showing a use state of the gas stove mat according to the embodiment of the present invention.

  In the following description, the surface on the exposed side when mounted on the gas stove will be referred to as the surface of the gas stove mat.

  First, referring to FIG. 3, the gas stove mat 1 according to the present invention is mounted around a gas burner 13 of the gas stove. A gas stove to be mounted has a top plate 11 having an opening 12 formed therein, a gas burner 13 disposed in the opening 12, and a gas stove disposed around the gas burner 13 and protruding from the surface of the top plate 11. And a burner ring 14. In the gas stove of the present embodiment, the surface of the top plate 11 around the gas burner 13 is finished flat.

  As shown in FIGS. 1 and 2, a gas stove mat 1 includes an annular mat body 2 which is a molded body of a metal foil. The mat body 2 has an outer dimension capable of covering the surface of the top plate around the gas burner, an inner peripheral portion 4 having an opening 3 formed in a central portion, and an outer peripheral portion of the inner peripheral portion 4. An annular step portion 5 formed to have a step at a position, and an outer peripheral portion 6 extending outward from the step portion 5 are provided. The inner peripheral portion 4 is formed so as to protrude from the outer peripheral portion 6 to the surface side via the step portion 5. When the gas stove has a plurality of gas burners, the gas stove mat is usually provided for each gas burner.

  The mat body 2 is made of, for example, an aluminum foil having a thickness of 10 to 100 μm. In this example, the opening portion 3, the inner peripheral portion 4, the step portion 5, and the outer peripheral portion 6 of the annular mat body 2 are concentric with each other. It is formed. The main parts of the inner peripheral part 4 and the outer peripheral part 6 are formed flat.

  The hole diameter d1 of the opening portion 3 provided in the inner peripheral portion 4 is larger than the inner diameter of the burner ring (the hole diameter of the opening through which the gas burner 13 is inserted) and the outer diameter R of the burner ring (see FIG. 7B). ) Is set to a smaller diameter. The hole diameter d1 is set so as not to interfere with a spark plug provided at the base of the gas burner or a safety device for preventing extinguishing.

  As shown in FIG. 3, the step portion 5 stands up from the outer peripheral portion 6 and has a shallow cylindrical shape. The outer peripheral portion 6 may be vertically erected, but may be slightly inclined toward the inner peripheral portion 4 as illustrated. The diameter d2 of the step 5 shown in FIG. 1 is set equal to or larger than the outer diameter R of the burner ring 14 (see FIG. 7B).

  The outer peripheral portion 6 is a portion continuously extending outward from the step portion 5, and its outer diameter d3 is set to a dimension capable of covering the surface of the top plate around the gas burner. Preferably, the outer diameter d3 is set such that the outer peripheral edge 2b of the mat main body 2 is located outside a position where the virtue attached around the gas burner can come into contact with the surface of the top plate (for example, 220 to 220). 245 mm).

  The protruding height h of the inner peripheral portion 4 with respect to the outer peripheral portion 6 shown in FIG. 2 is set so as to correspond to the height at which the burner ring protrudes from the surface of the top plate, and is usually set in the range of 5 to 10 mm. Is done.

  The mat body 2 further includes a bank portion 9 formed by erecting the outer peripheral edge 2 b of the outer peripheral portion 6. In the illustrated example, the embankment portion 9 is formed so that the surface side has a concave curved surface, but the shape is not particularly limited, and the embankment portion 9 is formed such that the surface forms a conical surface or a cylindrical surface. Is also good. The starting position of the embankment portion 9 is a position that does not interfere with the outer periphery of the gorge, and the height dimension of the outer peripheral portion 6 is set to a size that can prevent the spilled liquid from exceeding the embankment portion 9. You.

  The outer peripheral portion 6 further includes at least one annular liquid stopper 7 formed so as to protrude from the surface of the mat body 2. The liquid stopper 7 is provided at a position that does not interfere with the position where the virtue 15 is in contact with the mat body 2, and is formed so that its cross section has a triangular shape. In addition, the height dimension is set so as not to interfere with the height 15 and is set lower than the height of the step portion 5. This is because when the height of the liquid stopper 7 is higher than the step 5, the liquid accumulated between the step 5 and the liquid stopper 7 flows to the inner side of the burner ring 14 beyond the step 5. This is to avoid this problem.

  As shown in FIG. 3, the gas stove mat 1 is placed on a top plate 11 around a gas burner 13 in use, and a pit 15 is further placed thereon. The mat body 2 has an outer diameter capable of covering the surface of the top plate 11 around the gas burner 13, and the hole diameter of the opening 3 is smaller than the outer diameter of the burner ring 14. The step portion 5 has an outer diameter set substantially equal to the outer diameter of the burner ring 14. Further, the projecting height h of the inner peripheral portion 4 with respect to the outer peripheral portion 6 corresponds to the projecting height of the burner ring 14. On the other hand, the gotoku 15 includes a base 15b placed on the top plate 11 and an arm 15d for supporting a pot or the like, and a lower end 15a located on the inner peripheral side of the base 15b, By being fitted to the outer periphery of the burner ring 14 via the step 5, it is mounted on the top plate 11. The liquid stopper 7 of the mat body 2 is arranged outside the lower tip 15a of the virtues 15 so as not to interfere with the base 15b of the virtues 15. The embankment portion 9 of the mat body 2 is arranged outside the outer peripheral portion 15c of the virtues 15 so as not to interfere with the virtues 15.

  With such a configuration, when the gas stove mat 1 is attached to the gas stove, the gas stove mat 1 can seamlessly cover an area from the peripheral edge of the burner ring 14 to the top plate 11, and the mat main body 2 includes the burner ring 14 and the burner ring 14. It can appropriately contact the surface of the top plate 11. The liquid or the like spilled at the time of cooking falls along the inner peripheral side of the arm 15d of Gotoku 15 and falls on the surface of the burner ring 14, or falls along the outer peripheral side of the arm 15d of Gotoku 15 and falls on the surface of the top plate 11. there's a possibility that. However, by attaching the gas stove mat 1 configured as described above, it is possible to prevent the dropped liquid from contacting a part of the surface of the burner ring 14 and the top plate 11 around the burner ring 14, Since this liquid is prevented from entering the gap between the top plate 11 and the burner ring 14, these stains can be reliably prevented.

  In addition, since the mat body 2 includes the embankment portion 9, the liquid spilled onto the mat body 2 can be reliably prevented from flowing out, so that the effect of preventing the top plate from being soiled is improved.

  Further, the liquid stopping portion 7 formed outside the step portion 5 functions as a weir or a resistance against a liquid which is spilled during cooking and flows from the inside to the outside of the mat body 2. That is, when the liquid spilled from the pot or the like falls to a position inside the liquid stopper 7 such as on the surface of the inner peripheral part 4 and the amount of the liquid is small, the liquid stopper 7 Is blocked and the liquid can be prevented from reaching the outer peripheral portion 6. When the amount of the spilled liquid is large, the liquid stopper 7 gives a resistance to the flow of the liquid to reduce the flow velocity, thereby preventing the liquid from flowing out of the mat body 2 and preventing the liquid from flowing out of the mat body 2. Can be prevented from becoming dirty.

  In the case where a locking structure such as a notch is provided on the surface of the burner ring 14 for positioning the virtue 15, for example, the mat 1 for the gas stove is attached to the mat body 2 as described above. The inner peripheral portion 4 may cover and hide the locking structure of the burner ring 14. Therefore, as shown in FIG. 1B, a mark n for indicating the position of the locking structure of the burner ring 1 may be provided on the surface of the mat body 2, for example, on the surface of the inner peripheral portion 4. When the gas stove mat 1 is mounted around the gas burner, the mark portion n displayed on the surface of the mat body 2 is aligned with the position of the locking structure on the burner ring 14 so that the mat body 2 The sign n allows the position of the lock 15 to be grasped. Therefore, even after the gas stove mat 1 has been mounted, it is possible to easily attach the virtue 15 to an appropriate position.

  The gas stove mat of the present embodiment further has the following configuration. FIG. 4 is an enlarged view of the inner peripheral side of the gas stove mat shown in FIG. 5A and 5B are cross-sectional views showing another state of use of the gas stove mat according to the embodiment of the present invention, wherein FIG. 5A shows a state before attaching a virtue, and FIG. FIG. FIG. 6 is an enlarged view of the outer peripheral side of the gas stove mat shown in FIG.

  As shown in FIG. 4, the inner peripheral portion 4 of the mat body 2 further includes a first rim winding portion 8 formed by rim winding on an inner peripheral edge 2 a along the opening 3. The first edge winding portion 8 is formed by winding the edge of the opening portion 3 from top to bottom. In this example, the first edge winding portion 8 is set so that its lower end is located near the lower surface of the inner peripheral portion 4. You. Since the apparent cross-sectional area (section coefficient) of the inner peripheral edge 2a is increased by forming the first rim winding portion 8, the strength of the inner peripheral edge 2a of the inner peripheral portion 4 (the peripheral edge of the opening portion 3) is improved. Can be. In addition, the first rim winding portion 8 is provided with a dike function for the spilled liquid by protruding from the inner peripheral portion 4 to the surface side with a size corresponding to the diameter after winding (for example, 0.5 to 1 mm). It is possible. Note that the winding direction, the winding radius, and the like of the first edge winding portion 8 are not limited to the present embodiment.

  Further, the inner peripheral portion 4 is adjacent to the step portion 5 and has an annular first gentle slope portion S1 having a first gradient θ1 descending toward the step portion 5, and adjacent to the first gentle slope portion S1. A second gentle slope portion S2 descending toward the step portion 5 and having a second slope θ2 larger than the first slope θ1, and a flat surface including the opening portion 3 adjacent to the second gentle slope portion S2. A ring cover S3.

  When the inner peripheral portion 4 is configured as described above, the boundary between the first gentle slope portion S1 and the step portion 5, the boundary between the first gentle slope portion S1 and the second gentle slope portion S2, and the second The bent portions are formed at three places on the boundary between the gentle slope portion S2 and the ring cover portion S3. Further, since the second gradient θ2 is larger than the first gradient θ1, a concave portion is formed between the first gentle slope portion S1 and the second gentle slope portion S2 when viewed from the front side.

  The above configuration of the inner peripheral portion 4 has the following effects. As shown in FIG. 5 (A), when the base 15 b of the virtues 15 is attached to the outer periphery of the burner ring 14, when the diameter of the step 5 is larger than the diameter of the burner ring 14, As shown in FIG. 5 (B), it is necessary to crush a part of the inner peripheral part 4 and the step part 5 at the lower tip part 15a of the virtue 15. In this example, three bent portions are formed close to the step portion 5 and the recess between the first gentle slope portion S1 and the second gentle slope portion S2 is formed in the concave portion. The area near the step 5 is easily deformed by the load acting on the step 5. As a result, it becomes easy to crush a part of the inner peripheral part 4 and the step part 5 with the lower tip part 15a of the virtues 15. When the diameter of the step portion 5 is larger than the inner diameter of the lower end portion 15a of the lower end 15a, the bent portion formed by the flat ring cover portion S3 and the second gentle slope portion S2 and the first gentle slope surface are formed. Each of the bent portions formed by the portion S1 and the second gentle slope portion S2 also serves as a guide for positioning when the pentagon 15 is mounted. As a result, the deformation of the mat body 2 along the stepped portion 5 can be equalized, so that a displacement between the center of the inner peripheral portion 4 and the center of the outer peripheral portion 6 is prevented, and the mat for the gas stove can be properly used. A proper mounting state can be ensured. In the case where a bent portion formed by the first gentle slope portion S1 and the second gentle slope portion S2 is provided as a guide for positioning when the goto 15 is attached, the present invention is not limited to the form in which a recess is formed between both. , May be formed on the convex portion. However, from the viewpoint of the ease with which the step portion 5 is crushed, it is preferable that a recess is formed between the first gentle slope portion S1 and the second gentle slope portion S2.

  As shown in FIG. 6, the mat body 2 further includes a second rim winding portion 10 formed by rim wrapping on the outer peripheral edge 2 b of the outer peripheral portion 6. The second edge winding portion 10 in this example is formed by winding the edge of the embankment portion 9 from top to bottom, and the lower end thereof is set so as to be located near the upper end of the embankment portion 9. Since the apparent cross-sectional area (cross-sectional modulus) of the outer peripheral edge 2b is increased by forming the second edge winding portion 10, the strength of the outer peripheral edge 2b of the mat body 2 can be improved. In addition, by protruding the second edge winding portion 10 from the embankment portion 9 with a size corresponding to the diameter (for example, 1.5 to 3 mm) after entrainment, it is possible to improve the embankment function against the spilled liquid. is there. In addition, the winding direction, the winding radius, and the like of the second edge winding portion 10 are not particularly limited.

  In addition, the mat body is annular, but is not limited to a circle, and may be a rectangle, a square, a regular hexagon, or the like. When a gas stove having a plurality of gas burners is applied, the mat body may cover the entire surface of the top plate and include a plurality of openings corresponding to the plurality of gas burners. Further, the mat body may be provided with only one of them, in addition to having both the liquid stopping portion and the embankment portion, or both may be omitted.

  Only one liquid stopper may be provided on the mat body, but two or more liquid stoppers may be provided. The cross-sectional shape of the liquid stopper is not limited to a triangular shape, and may be, for example, a semi-circular or rectangular cross-sectional shape.

  The shape of the opening at the inner peripheral portion is circular in the above description, but can be changed according to the shape of the burner ring, such as elliptical. When an ignition plug, a safety device for preventing extinguishing, and the like are provided near the base of the gas burner, the opening may be formed to have a cutout to avoid these. Further, the first gentle slope portion and the second gentle slope portion provided on the inner peripheral portion may be omitted.

  Furthermore, only one of the first rim winding portion formed on the inner peripheral portion and the second rim winding portion formed on the outer peripheral portion may be provided, or both may be omitted.

  The sign portion may be provided on the surface of the step portion or the outer peripheral portion other than the inner peripheral portion, and may be omitted in some cases.
