Description

Technical Field

[0001] The present invention relates to a mat installed around a gas burner of a gas stove.

Background Art

[0002] Since food scraps, oil, and seasonings scatter during cooking, or the boiling liquid spills, etc., the top plate of a gas stove is likely to get dirty. Therefore, various mats for gas stoves that cover this top plate have been devised. When the top plate is covered with a mat for a gas stove, dirt adheres to the mat for the gas stove, so the top plate itself is less likely to get dirty. Also, the dirt on the mat for the gas stove can be wiped off relatively easily.

[0003] As such a mat for a gas stove, as in Patent Document 1, there is known a donut-shaped sheet body in which an opening for inserting a gas burner in a gas stove is formed, and a plurality of opening auxiliary lines such as perforations are formed concentrically with the opening. In the mat for a gas stove of Patent Document 1, by cutting off the opening auxiliary line and adjusting the size of the opening, it becomes possible to install it around gas burners with various outer diameters.

[0004] Also, where a burner ring is installed around the gas burner on the top plate, a mat for a gas stove configured to cover from around the gas burner to outside the outer periphery of the burner ring has been developed, as in Patent Document 2. Specifically, where there is a step between the outer peripheral portion of the burner ring and the top plate, the mat for a gas stove of Patent Document 2 has an opening for inserting the gas burner and an inner peripheral portion that covers the burner ring, an outer peripheral portion that covers outside the above step of the top plate, and a step portion that connects these inner peripheral portion and outer peripheral portion with a height difference corresponding to the height of the above step. Because the inner circumference makes proper contact with the burner ring and the outer circumference makes proper contact with the top plate, it can cover a wide area from the burner ring to the top plate, thus preventing dirt from accumulating. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2015-7513 [Patent Document 2] Japanese Patent Publication No. 2019-219065 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] However, in both Patent Documents 1 and 2, the opening diameter of the gas range mat is set to be considerably larger than the outer diameter of the gas burner in order to allow the gas burner to pass through easily. As a result, the area near the inner circumference of the burner ring, which is located inside the opening, may become soiled due to spills during cooking.

[0007] In conventional gas ranges, the parts surrounding the gas burner were removable, so if the burner ring got dirty, it could be removed and cleaned, and if the dirt couldn't be removed by cleaning, only the burner ring needed to be replaced. However, in recent years, gas ranges have increasingly featured designs where surrounding parts such as burner rings cannot be removed, in consideration of ease of cleaning. In such cases, if the dirt cannot be removed even after cleaning, the entire gas range had to be replaced. Therefore, the need to prevent burner ring contamination has increased even further in recent years. .

[0008] In this regard, one could consider narrowing the opening of the gas range mat to prevent dirt from accumulating near the inner circumference of the burner ring. However, the outer circumference of the gas burner and the area near the inner circumference of the burner ring are equipped with a spark plug (electrode) and a safety device (flame detection sensor) to prevent flame failure. Therefore, simply narrowing the opening could cause interference between the ignition plug, the safety device to prevent flame failure, and the mat, potentially hindering the ignition of the gas burner and the operation of the safety device, which could lead to a fire.

[0009] Therefore, the problem to be solved by the present invention is to prevent the burner ring from becoming dirty during cooking in a gas range mat without interfering with the operation of the ignition plug or the safety device for preventing flame failure. [Means for solving the problem]

[0010] To solve the above-mentioned problems, the gas range mat according to the invention comprises: a mat body capable of covering a burner ring installed around a gas burner on the top plate of a gas range; an opening formed in the mat body through which the gas burner can be inserted, having a diameter approximately the same as the outer diameter of the gas burner; and a cutout formed in the mat body extending from the outer diameter of the opening, through which an ignition plug and a safety device for preventing flame failure attached to the gas burner can be inserted.

[0011] By configuring the gas range mat according to the invention in this way, it becomes possible to cover almost the entire burner ring with the mat itself, thereby preventing the burner ring from becoming soiled during cooking. In particular, because the opening through which the gas burner can be inserted is almost the same diameter as the gas burner, spills and other contaminants during cooking can be effectively prevented from getting on the inner circumference of the burner ring. In this context, "the opening is approximately the same diameter as the gas burner" means that the opening diameter is the same as or slightly larger than the outer diameter of the gas burner. "Slightly larger" means that there is only enough space near the inner circumference of the burner ring to adequately prevent spills and other contamination during cooking. Specifically, this means that the opening diameter is at most a few millimeters larger than the outer diameter of the gas burner.

[0012] Furthermore, the gas range mat according to the invention has a notch around the opening, and when installed, the ignition plug and the safety device to prevent flame failure are located within this notch. Therefore, the mat body does not interfere with the ignition plug or the safety device to prevent flame failure, and their operation is not hindered. The notches may be provided in multiple locations so that the spark plug and the safety device for preventing flame failure can be inserted individually, or in a single location so that they can be inserted together.

[0013] In the gas range mat according to the invention, it is preferable to adopt a configuration in which the notches are provided in multiple locations along the outer circumference of the opening so that ignition plugs and safety devices for preventing flame failure, each arranged in a different pattern, can be inserted through them.

[0014] While various arrangement patterns exist for ignition plugs and flame failure prevention safety devices depending on the gas range manufacturer and the size of the gas burner, a single gas range mat can be used for various gas ranges by positioning the cutouts so that all of these multiple patterns can be inserted.

[0015] In the gas range mat according to the invention, the burner ring is connected to the gas range It is preferable to adopt a configuration that further includes markers at positions corresponding to the interlocking protrusions and recesses provided for alignment.

[0016] When the burner ring is covered with the mat body, the fitting concave and convex portions of the burner ring become invisible, making it difficult to fit the grate on top of it. However, by providing a mark at a position corresponding to the fitting concave and convex portions of the mat body, the position of the fitting concave and convex portions of the burner ring can be confirmed even from above the mat body. Therefore, the operation of fitting the fitting concave and convex portions together can be easily performed. As the mark, printing, holes, cuts, transparent parts, etc. can be considered, but it is more preferable to use holes because they are easy to form and the fitting concave and convex portions can be directly visually recognized through the holes.

[0017] In the mat for a gas range according to the invention, it is preferable to adopt a configuration in which a plurality of the marks are provided in the circumferential direction of the mat body so that the fitting concave and convex portions with different arrangement patterns and numbers can all be aligned.

[0018] The fitting concave and convex portions of the burner ring and the grate have various arrangement patterns and numbers depending on the manufacturer of the gas range, etc. By providing marks so that all of these multiple patterns can be aligned, one mat for a gas range can be used for multiple types of gas ranges.

[0019] In the mat for a gas range according to the invention, it is preferable to adopt a configuration in which the mat body has a circular top plate that is placed on the burner ring and a skirt portion that hangs down from the outer periphery of the top plate by a height corresponding to the height difference between the burner ring and the top plate.

[0020] By generally matching the shape of the mat body with the shape of the burner ring, it becomes easy to cover the burner ring, and it is possible to further prevent the adhesion of boiled juice or the like to the burner ring.

[0021] In the mat for a gas range according to the invention, it is preferable to adopt a configuration in which the mat body further has a border winding portion on the outer periphery of the skirt portion.

[0022] With such a configuration, the cooking juice or the like that spills and spreads on the mat body is blocked by the edge-wrapping portion, so that it does not flow out from the outer periphery of the mat body onto the top plate, and the top plate can be prevented from being soiled.

Advantages of the Invention

[0023] Since the gas stove mat according to the invention is configured as described above, it is possible to prevent the burner ring from being soiled during cooking without hindering the operation of the ignition plug or the safety device for preventing flameout.

Embodiments for Carrying Out the Invention

[0025] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The gas range mat 1 in the embodiment shown in Figures 1 to 4 is installed on the top plate of the gas range 50 so as to cover the burner ring 52 located around the gas burner 51, as shown in Figures 1 to 3, to prevent food scraps, oil and seasoning liquids from splashing or broth from boiling over during cooking, which can cause dirt to adhere to the burner ring 52.

[0026] As shown in Figure 4, the gas range mat 1 of this embodiment comprises a mat body 10 made by press-molding a metal foil such as aluminum foil. The thickness of the metal foil is not particularly limited, but 30 to 50 μm is preferred. If the thickness exceeds 50 μm, there is a risk of easily cutting your hands on the edges of the opening 20 described later, and if the thickness is less than 30 μm, it may be too thin and easily torn, making it difficult to mold the mat body 10. The mat body 10 consists of a circular top plate 11, a skirt portion 12 hanging down from the periphery of the top plate 11, and an upward-curving edge portion 13 formed on the periphery of the skirt portion 12, and as a whole it has the shape of an inverted shallow dish. A flange 12a is attached to the skirt portion 12.

[0027] The outer diameter of the top plate 11 of the mat body 10 is set to be approximately equal to or slightly larger than the outer diameter of the burner ring 52 of the gas range 50, and the height of the skirt portion 12 is set to be approximately equal to or slightly larger than the protrusion height of the burner ring 52 from the top plate. Therefore, when the mat body 10 is placed over the burner ring 52, almost the entire burner ring 52 is covered. This prevents dirt from adhering to the burner ring 52.

[0028] As shown in Figures 1 to 3, with the mat body 10 installed, the flange 12a and edge banding 13 attached to the skirt portion 12 are positioned on the top plate 53 outside the burner ring 52. Even if cooking liquids or other substances adhering to the top plate 11 flow down from the outer edge of the top plate 11, they are caught by the flange 12a, thus preventing the top plate 53 from becoming soiled. Even if the broth or other liquid that has flowed down onto the flange 12a tries to flow further over the mat body 10, the edge banding 13 blocks it, thus preventing the contamination from spreading. The edge banding 13 also helps prevent injuries to the hands.

[0029] As shown in Figure 4, a circular opening 20 is formed in the center of the top plate 11 of the mat body 10. The opening 20 is formed by punching it out with a die-cutting tool. The diameter of the opening 20 is set to be approximately equal to or slightly larger than the outer diameter of the gas burner of the gas range, and as shown in Figures 1 to 3, the gas burner 51 is inserted through this opening 20 when the mat body 10 is installed. The gas burner 51 has a temperature sensor 51a that protrudes upward from its center and is covered with a burner cap 51b. Since there is almost no gap between the opening 20 and the gas burner 51, dirt from spills during cooking is prevented from adhering to the inner circumference of the burner ring 52 through the gap.

[0030] As shown in Figure 4, a notch 30 is formed on the edge of the opening 20 of the top plate 11 of the mat body 10, and is continuous with the opening 20. The notch 30 is shaped by punching it out with a die-cutting blade or the like. It has been done. The notch 30 extends in the outer diameter direction of the opening 20 and has a constant width in the circumferential direction of the opening 20, and has an overall rectangular shape. Multiple notches 30 are arranged in parallel in a predetermined pattern around the circumferential direction of the opening 20. In each notch 30, the radial length is almost uniform, but the circumferential width varies. As shown in Figures 1 to 3, with the mat body 10 installed, the ignition plug 51c and the safety device 51d for preventing flame failure, which are attached to the outer circumference base of the gas burner 51 and face the flame opening, are inserted through the notch 30. As a result, the mat body 10 does not come into contact with or cover the spark plug 51c or the flame failure prevention safety device 51d, thereby preventing interference with the operation of the spark plug 51c and the flame failure prevention safety device 51d.

[0031] The arrangement pattern of the notches 30 is set to match the arrangement pattern of the spark plug 51c and the flame failure prevention safety device 51d in a typical commercially available gas range 50. In other words, as shown in Figure 5, there are several arrangement patterns for the spark plug 51c and the flame failure prevention safety device 51d in a typical gas range 50. In any of these arrangement patterns, the position and number of notches 30 are determined so that both the spark plug 51c and the flame failure prevention safety device 51d pass through the notches 30. This makes it possible to use a single gas range mat 1 for multiple types of gas ranges 50.

[0032] As shown in Figure 4, a hole 40 is formed near the outer edge of the top plate 11 of the mat body 10, serving as a marker. The hole 40 is not continuous with the opening 20 and the notch 30. The holes 40 are rectangular in shape, and multiple holes are arranged in parallel in a predetermined pattern around the circumferential direction of the top plate 11. As shown in Figures 2 and 3, in the gas range 50, the burner ring 52 and the trivet 54 for supporting pots and pans have interlocking protrusions 52a and 54a for aligning their positions with each other. When the mat body 10 is placed on the burner ring 52, aligning the hole 40 with the interlocking protrusions of the burner ring 52 makes it easy to align the trivet from above. In the illustration, the interlocking protrusions 54a of the trivet 54 are inserted through the hole 40.

[0033] The arrangement pattern of the holes 40 is set to match the arrangement pattern of the fitting recesses 52a of the burner ring 52 and the fitting recesses 54a of the trivet 54 in a typical commercially available gas range 50. In other words, as shown in Figure 5, there are several possible arrangement patterns for the fitting recesses 52a and 54a of the burner ring 52 and trivet 54 in a typical gas range 50. In any of these arrangement patterns, the position and number of holes 40 are determined so that they can be matched with the fitting recesses 52a of the burner ring 52. This makes it possible to use a single gas range mat 1 for multiple types of gas ranges 50.

[0034] The embodiments disclosed herein are illustrative in all respects and are not restrictive. The scope of the present invention is defined by the claims and includes all modifications and variations within the scope of the claims and in the sense equivalent thereto.

[0035] In this embodiment, the mat body 10 is shaped like an inverted shallow dish made by press-molding metal foil, but the shape of the mat body 10 is not limited to this, and can be made of, for example, silicone rubber or It may be made of a heat-resistant and flexible sheet body consisting of non-combustible paper, glass fiber sheets, or composites thereof, and may be placed over the burner ring 52 while being deformed. Furthermore, even if the mat body 10 is made of metal foil, its shape is not limited to the embodiment, and for example, the flange 12a and the edge wrapping portion 13 can be omitted. In this embodiment, the mat body 10 is configured to cover only the area around the gas burner 51, but it is not limited to this configuration. For example, as shown in Figure 6, it may be configured to cover almost the entire top plate 53. In that case, the mat body 10 will be provided with multiple openings 20 and notches 30 attached to their edges, through which each of the multiple gas burners 52 on the top plate 53 can be inserted.

[0036] The arrangement pattern and number of the notches 30 and holes 40 are not limited to the embodiment. For example, in this embodiment, the notches 30 and holes 40 are arranged to accommodate multiple arrangement patterns of spark plugs 51c, safety devices 51d for preventing flame failure, and fitting protrusions 52a and 54a. However, for a product dedicated to a specific gas range, the notches 30 and holes 40 may be arranged to accommodate only a single arrangement pattern of spark plugs 51c, safety devices 51d for preventing flame failure, and fitting protrusions 52a and 54a. In that case, the number of notches 30 and holes 40 will be reduced, which will further prevent soiling of the burner ring 52. In this embodiment, the hole 40 is formed only in the top plate 11, but as shown in Figure 7, it may also be formed extending from the top plate 11 to the skirt portion 12, or from the top plate 11 to the flange 12a. Alternatively, as shown in Figure 8, the spark plug 51c and the safety device 51d for preventing flame failure may be housed together in a single notch 30.

[0037] In this embodiment, the notch 30 is rectangular, but its shape is not limited to this, as long as the spark plug 51c and the safety device 51d for preventing flame failure can be inserted through it, and it may be semicircular, semi-elliptical, or the like.

[0038] In this embodiment, a hole 40 is shown as a marker, but the type of marker is not limited to this. Examples include printing a mark, providing a recess or protrusion, or providing a transparent portion. Also, even when a hole 40 is used as a marker, its shape is not limited to this embodiment and may be circular, elliptical, polygonal, etc. Furthermore, the marker can be omitted.
