<Embodiment>
The gas stove 1 according to this embodiment will be described in detail below.

(1) Overall The gas stove 1 is a stove that uses gas as fuel. The gas stove 1 according to this embodiment is a built-in stove in which the device body 2 is dropped into an opening formed in the worktop of a kitchen counter, but in the present invention, the gas stove 1 may be a table stove that is used by placing it on an installation surface (for example, a table, a stove stand, etc.).

In this embodiment, the gas stove 1 is a gas stove with a grill. With a gas stove with a grill, food stored in the grill chamber can be grilled. However, the gas stove 1 according to the present invention does not have to have a grill function. Instead of a grill function, the gas stove 1 may have, for example, a multi-grill with a range function, oven function, and rice cooking function, or may have any of a range, oven, or rice cooker.

For ease of explanation, the following directions are defined based on the manner in which the gas stove 1 is used. In other words, assuming a manner in which the user cooks while facing the gas stove 1, the "left-right direction" is defined as shown in FIG. 1. The direction from the gas stove 1 toward the user and along the horizontal plane is defined as the "forward direction," the opposite direction as the "rearward direction," and the two directions parallel to the forward and rearward directions are defined as the "front-rear direction." The direction perpendicular to the installation surface (the upper surface of the worktop) is defined as the "up-down direction." However, these definitions of directions are not intended to limit the manner in which the gas stove 1 according to the present invention is used.

As shown in FIG. 1, the gas stove 1 comprises a device body 2 having multiple (here, three) burners 22, a top plate 3, and a trivet 4.

(2) Device Body The device body 2 constitutes the main body of the gas stove 1. The device body 2 includes a housing 21 and a plurality of devices 22, 23. The gas stove 1 according to this embodiment has a plurality of burners 22 and a grill device 23 as the plurality of devices 22, 23.

(2.1) Housing The housing 21 is a box in the device body 2 that houses the devices. The housing 21 is formed in a rectangular parallelepiped shape and has an opening (not shown) on the top surface. As shown in Fig. 1, the front surface of the housing 21 is formed with an opening 211 for passing the grill door 231 and an opening 212 for passing the operating device 24 for igniting/extinguishing the devices and adjusting the flame power.

(2.2) Burner The burner 22 heats the cooking utensils (not shown) placed on the trivet 4. The burner 22 is a Bunsen burner that receives a supply of gas containing gas and performs premixed combustion. The burners 22 are arranged apart from each other in the housing 21. The device body 2 has, as the burners 22, two burners 22 located forward of the center in the front-rear direction of the top plate 3 and one burner 22 located rearward of the center. However, the device body 2 may have, as the burners 22, two burners 22 located rearward of the center in the front-rear direction of the top plate 3 that are separated in the left-right direction (i.e., the device body 2 may have four burners 22).

Here, in this specification, "cooking equipment" refers to tools used when cooking. Examples of cooking equipment include cooking containers such as pots, clay pots, frying pans, and kettles, as well as grills, heating plates, takoyaki plates, hot sandwich plates, waffle makers, etc.

As shown in FIG. 2, the burner 22 includes a burner body 221, a burner cap 222, an ignition plug 224, and a temperature sensor 225. The burner body 221 constitutes the main part of the burner 22. A gas supply passage (not shown) that leads to a fuel gas supply source such as city gas or LP gas is connected to the burner body 221. The upper end surface of the burner body 221 is open. The fuel gas supplied from the gas supply passage is mixed with air inside the burner body 221 and flows toward the opening on the upper end surface. A burner cap 222 is attached to the upper end surface of the burner body 221 so as to cover the opening.

The burner cap 222 is a part that is placed on the upper end surface of the burner body 221, and forms multiple flame ports 226 between the burner cap 222 and the upper end surface. A hole 223 is formed in the center of the burner cap 222. A temperature sensor 225 is passed through the hole 223 of the burner cap 222.

The temperature sensor 225 is used to measure the temperature of the cooking utensil placed on the trivet 4 and detect the temperature of the food being cooked inside the cooking utensil. The temperature sensor 225 is located in the center of the burner 22 when viewed from above (sometimes called a planar view). In this specification, the "center of the burner 22" means the center in a planar view of the part that protrudes above the upper surface of the top plate 3, and in this embodiment, means the center of the hole 223 of the burner cap 222. Therefore, the temperature sensor 225 is located in the center of the burner cap 222 when viewed in a planar view.

The upper end of the temperature sensor 225 protrudes upward from the upper end surface of the burner cap 222. The temperature sensor 225 is installed so that it can move up and down relative to the burner cap 222, and is elastically displaceable. Therefore, when a cooking utensil is placed on the trivet 4, the upper end surface of the temperature sensor 225 descends while in contact with the cooking utensil, and at this time, it elastically contacts the cooking utensil. When the upper end surface of the temperature sensor 225 comes into contact with the cooking utensil, the electrical signal generated by the temperature sensor 225 is processed by a controller (not shown), and the temperature of the cooking utensil can be measured. As a result, the temperature of the food contained in the cooking utensil can be detected.

(2.3) Grill device The grill device 23 is a device that can grill food stored in a grill chamber (not shown). The grill device 23 includes a grill chamber (not shown) having an opening on the front side, and a grill door 231 that opens and closes the opening of the grill chamber. The grill door 231 is attached via a support mechanism (not shown) so as to be movable in parallel along the front-rear direction relative to the grill chamber.

(3) Top Plate The top plate 3 is the uppermost plate of the gas stove 1. As shown in FIG. 1, the top plate 3 is formed in a substantially rectangular plate shape. The top plate 3 includes a cooking section 31, an exhaust section 32, and an outer peripheral edge section 33. The top plate 3 according to this embodiment is made of a metal plate in which the cooking section 31, the exhaust section 32, and the outer peripheral edge section 33 are integrally formed. Examples of the metal plate include aluminum, enamel, and fluorine-coated steel plate. However, in the present invention, the top plate 3 is not limited to a metal plate, and may be made of, for example, glass.

(3.1) Cooking section The cooking section 31 is an area for cooking and is an area that can receive liquid (e.g., boiling over, splashing, etc.). A trivet 4 is attached to the cooking section 31, and cooking utensils are placed on the trivet 4. As shown in Fig. 2, the cooking section 31 includes a planar receiving section 311 located below the exhaust section 32 and the outer peripheral edge section 33, a plurality of burner insertion holes 312 formed in the receiving section 311, and a plurality of outer peripheral sections 313 formed around each burner insertion hole 312. The burner insertion holes 312 penetrate the top plate 3, and the upper end of the burner 22 passes through them.

The outer peripheral portion 313 is formed around the burner insertion hole 312 and prevents liquid from entering the burner insertion hole 312. The outer peripheral portion 313 protrudes from the receiving portion 311 and can block the liquid received by the receiving portion 311 from moving toward the burner insertion hole 312. The outer peripheral portion 313 may be formed integrally with the receiving portion 311, or may be formed by attaching a separate member such as a burner ring. In this embodiment, the outer peripheral portion 313 is formed integrally with the receiving portion 311 by applying a drawing process.

In this embodiment, as described above, the outer peripheral portion 313 is integrally formed with the receiving portion 311, and the structure is such that liquids adhering to the outer peripheral portion 313 can be easily wiped off, so the burner insertion hole 312 is exposed. However, in cases where the outer peripheral portion 313 is formed of a burner ring, the burner insertion hole 312 may be covered with a cover.

As shown in FIG. 1, the top plate 3 is attached to the housing 21 of the device body 2 so that it rests on the upper end of the housing 21. When the top plate 3 is attached to the device body 2, the upper end of the burner 22 passes through the burner insertion hole 312 and protrudes above the upper surface of the outer periphery 313.

In addition to the function of blocking the liquid described above, the outer peripheral portion 313 also holds the positioning portions 52, 62 of the trivet 4, thereby positioning the trivet 4 relative to the top plate 3. The positioning of the trivet 4 by the outer peripheral portion 313 may be achieved by contact with the side of the outer peripheral portion 313 (the surface rising from the receiving portion 311), but in this embodiment, it is achieved by inserting the positioning portions 52, 62 of the trivet 4 into the recesses 314 (Figure 2) formed in the outer peripheral portion 313.

As shown in FIG. 2, the recesses 314 are formed at two locations, the front end and the rear end of the outer periphery 313. The recess 314 at the front end is open to the front and upward directions. The recess 314 at the rear end is open to the rear and upward directions. Therefore, when attaching the trivet 4 to the top plate 3, when the positioning portions 52, 62 of the trivet 4 are inserted from top to bottom into the recess 314, the positioning portions 52 (62) fit into the recess 314 as shown in FIG. 3.

(3.2) Exhaust Section The exhaust section 32 is a flat plate-shaped section in which an exhaust port is formed to let out the exhaust air from inside the grill chamber. As shown in Fig. 1, the exhaust section 32 is disposed behind the cooking section 31. An exhaust port cover 321 is removably attached to the exhaust port.

(3.3) Outer peripheral edge The outer peripheral edge 33 is a portion that surrounds the outer periphery of the cooking section 31 and rises from the outer edge of the cooking section 31. As shown in FIG. 3A, the outer peripheral edge 33 has a rising portion 331 and a top portion 332. The rising portion 331 rises from the outer edge of the receiving section 311 (i.e., the outer edge of the cooking section 31). The rising portion 331 is inclined with respect to the receiving section 311 so as to go upward as it goes outward from the edge of the receiving section 311. The top portion 332 protrudes along a horizontal plane from the upper end of the rising portion 331. The outer ends of the top portion 332 are connected to the side ends 34 of the top plate 3 for the outer peripheral edge 33 on the left and right sides and the front outer peripheral edge 33, and are connected to the exhaust section 32 (FIG. 1) for the rear outer peripheral edge 33.

(4) Trivet The trivet 4 is removably attached to the top plate 3 and supports cooking utensils on the burners 22. The trivet 4 is configured to collectively cover at least two of the multiple burners 22, and in this embodiment, covers three burners 22. In this embodiment, the trivet 4 is configured as a full trivet that covers the entire surface of the cooking section 31.

The trivet 4 is made of metal. Examples of metals that can be used to make the trivet 4 include enamel and stainless steel.

As shown in FIG. 4, the trivet 4 is composed of multiple (here, two) divisible segments 5, 6. Each of the segments 5, 6 is formed in a generally rectangular shape in plan view with its longitudinal direction in the left-right direction. In the following, the segment that covers the burner 22 located forward of the center of the top plate 3 in the front-to-rear direction is defined as the "front segment 5," and the segment that covers the burner 22 located rearward of the center of the top plate 3 in the front-to-rear direction is defined as the "rear segment 6."

(4.1) Front divided body The front divided body 5 is a divided trivet 4 that covers the front burner 22 among the burners 22 arranged in the front-rear direction. Therefore, the front divided body 5 according to this embodiment collectively covers both of the pair of left and right burners 22 on the front side, as shown in FIG.

As shown in FIG. 5(A), the position of the front split body 5 corresponding to the center C1 of the burner 22 is shifted in either the front-rear direction from the center C2 of the front split body 5 in the front-rear direction. Specifically, in this embodiment, the position of the front split body 5 corresponding to the center C1 of the burner 22 is located rearward of the center C2 of the front split body 5 in the front-rear direction.

For this reason, in the gas stove 1 according to this embodiment, even if a certain dimension or more is secured from the front end of the top plate 3 in order to keep the front burner 22 away from the user, the area in front of the burner 22 can be used as an area for placing cooking utensils. By keeping the burner 22 as far away from the user as possible, liquid can be prevented from reaching the user in the event of overflow from the cooking utensil, and the effects of the flame and heat of the burner 22 can be suppressed.

Figure 5(A) shows a plan view of the front divided body 5 when it is placed in the correct orientation, and Figure 5(B) shows a plan view of the front divided body 5 when it is installed in the opposite orientation. In this way, if the position of the front divided body 5 corresponding to the center C1 of the burner 22 is shifted in either the front or rear direction from the center C2 of the front divided body 5 in the front-to-rear direction, there is an advantage that when a cooking utensil is placed directly above the burner 22, it is easier to place other cooking utensils in other positions on the trivet 4.

If the front split body 5 is installed in the wrong position (sometimes called "incorrect installation"), as shown in Figure 5(B), part of the front split body 5 will enter the installation area of the rear split body 6, and the user will be unable to install the rear split body 6, allowing them to know for sure that the front split body 5 has been installed incorrectly.

As shown in FIG. 4, the front section 5 includes a frame portion 51, a plurality of positioning portions 52, a plurality of mounting portions 53, and a plurality of grounding portions 56.

(4.1.1) Frame portion The frame portion 51 is a skeletal portion that connects the positioning portion 52 and the multiple mounting portions 53. The frame portion 51 includes a frame portion 511, a connecting portion (first connecting portion 512) that connects the frame portion 511 and the mounting portions 53, and a connecting portion (second connecting portion 513) that connects the frame portion 511 and the positioning portion 52.

The frame 511 is formed into a generally rectangular frame shape in a plan view. The frame 511 surrounds a pair of left and right burners 22 located at the front of the multiple burners 22. The lower surface of the frame 511 faces the upper surface of the cooking section 31 of the top plate 3. When the front divided body 5 is attached to the top plate 3, the front side of the frame 511 runs along the front outer peripheral edge 33 of the top plate 3, both left and right sides of the frame 511 run along the left and right outer peripheral edges 33 of the top plate 3, and the rear side of the frame 511 runs along the center of the cooking section 31 in the front-to-rear direction.

The cross-sectional shape of the frame 511 is not particularly limited, but examples include a vertically elongated rectangle, a circle, a rectangle with rounded corners, a flat plate, a pipe, etc. Here, it is formed in a rectangle with rounded corners (4 mm wide, 10 mm long).

The first connecting parts 512 rise from the frame part 511 and support the multiple mounting parts 53. Each first connecting part 512 is formed in a plate shape and is fixed to the frame part 511 by welding. Note that the fixing of the frame part 511 and the first connecting parts 512 is not limited to welding, and may be realized by, for example, fitting, cutting, screwing, etc.

The second connecting portion 513 connects the positioning portion 52 and the frame portion 511, so that the frame portion 511 can be positioned in the correct position by the positioning portion 52, which is positioned relative to the outer periphery 313. The second connecting portion 513 extends from the frame portion 511 toward the outer periphery 313, and fixes the positioning portion 52 to the frame portion 511.

(4.1.2) Positioning Part The positioning part 52 is a part that is positioned relative to the outer periphery 313 of the top plate 3. As shown in FIG. 3, the positioning part 52 is configured with a tip that is inserted into the recess 314 of the outer periphery 313. The front divided body 5 has two positioning parts 52 for one burner 22. The two positioning parts 52 are located on a straight line that passes through the center of the burner 22 and face each other. Here, the positioning part 52 that is inserted into the front recess 314 is referred to as the "first positioning part 521," and the positioning part 52 that is inserted into the rear recess 314 is referred to as the "second positioning part 522." When the first positioning part 521 is inserted into the front recess 314 and the second positioning part 522 is inserted into the rear recess 314, the trivet 4 is positioned in both the front-rear direction and the left-right direction.

As shown in FIG. 3B, each positioning portion 52 is tapered so that its thickness decreases toward the bottom end. In this embodiment, only the bottom end of the positioning portion 52 is tapered, but it may also be tapered from the center toward the bottom end in the vertical direction, or from the top end to the bottom end. The positioning portion 52 is tapered so that it can be smoothly inserted into the recess 314.

(4.1.3) Placement section The placement section 53 is a section on which cooking utensils are placed. The upper end surfaces of the placement sections 53 are located on the same plane. As shown in Fig. 4, the placement section 53 includes a plurality of claws 54 arranged radially from the center of the burner 22, and auxiliary sections 55 that constitute the placement section 53 other than the claws 54.

As shown in FIG. 3(A), the claw portion 54 is tapered so that the vertical width dimension decreases toward the tip on the center side of the burner 22. As shown in FIG. 4, the auxiliary portion 55 is composed of a combination of multiple vertical members 551 extending in the front-rear direction and multiple horizontal members 552 extending in the left-right direction. The multiple vertical members 551 and multiple horizontal members 552 are formed, for example, in a lattice shape.

(4.1.4) Grounding Part The multiple grounding parts 56 are parts of the trivet 4 that rest on the upper surface of the top plate 3 (more specifically, the receiving part 311). The grounding parts 56 are made of a cushioning material. The cushioning material suppresses the generation of contact noise between the parts when the trivet 4 comes into contact with the top plate 3. The cushioning material is preferably made of a material softer than the metal that makes up the frame part 51, and examples of the cushioning material include elastomer, soft synthetic resin, hard synthetic resin, resin foam, wood, and cloth.

The grounding portion 56 is provided on the frame portion 51. The multiple grounding portions 56 are attached at intervals along the frame portion 511. The multiple grounding portions 56 according to this embodiment are attached to the frame portion 511. The attachment of the grounding portion 56 to the frame portion 511 is achieved by, for example, adhesive bonding, fitting, adhesion, welding, two-color molding, screwing, pinning, riveting, a snap-fit structure, wrapping, etc.

When no cooking utensils are placed on the trivet 4, the grounding portion 56 of the trivet 4 rests on the receiving portion 311, and a gap is formed between the bottom end surface excluding the grounding portion 56 and the upper surface of the top plate 3. This reduces the generation of contact noise between the components that occurs when the trivet 4 and the top plate 3 come into contact when the trivet 4 is installed on the top plate 3 or when cooking utensils are placed on the trivet 4.

Here, the first connecting portion 512 that supports the mounting portion 53 is connected to the portion between the adjacent grounding portions 56 in the frame portion 511. Therefore, when a cooking utensil is placed on the mounting portion 53 (e.g., the claw portion 54), the load is applied to the frame portion 511 via the first connecting portion 512, and the portion between the grounding portions 56 in the frame portion 511 may bend. When the frame portion 511 is bent, the mounting portion 53 moves closer to the burner 22, which affects the combustion performance.

Therefore, in the trivet 4 according to this embodiment, as shown in Fig. 6, a restricting surface 571 is formed between the bottom surface of the grounding portion 56 and the bottom surface of the frame portion 511. Note that Fig. 6 is an explanatory diagram comparing the height positions of the cross section of the grounding portion 56 and the cross sections of the frame portion 511 and the restricting surface 571 to explain the height relationship between the two.

As shown in FIG. 6, the dimension L2 between the regulating surface 571 and the underside of the grounding portion 56 is smaller than the dimension L1 between the underside of the frame portion 511 and the underside of the grounding portion 56. Therefore, since the regulating surface 571 is located between the underside of the grounding portion 56 and the underside of the frame portion 511, even if the portion between the grounding portions 56 in the frame portion 511 warps, the regulating surface 571 comes into contact with the top plate 3, preventing the frame portion 511 from warping further. Therefore, when installing the trivet 4, it is possible to minimize the warping of the portion between the grounding portions 56 in the frame portion 511 while suppressing the generation of contact noise between the components.

6, the restricting surface 571 is composed of the lower surface of the restricting portion 57 that protrudes downward from the lower end of the first connecting portion 512 and the lower end of the second connecting portion 513. The restricting portion 57 is provided on the first connecting portion 512 and the second connecting portion 513, so that the restricting portion 57 can be positioned between adjacent grounding portions 56. Note that while FIG. 6 shows that the restricting portion 57 is provided on the first connecting portion 512 and the second connecting portion 513 that support the claw portion 54, the restricting portion 57 is also provided on the lower end of the first connecting portion 512 that supports the auxiliary portion 55.

The restricting portion 57 is not limited to the first connecting portion 512 and/or the second connecting portion 513, and may be provided, for example, on the frame portion 511. The restricting surface 571 is formed in a flat shape, but there is no particular limit to the shape, and it may be, for example, an arc shape, a spherical shape, a line shape, a point shape, etc.

By providing the regulating surfaces 571 in multiple locations, even if the user were to remove and lose the grounding portion 56 for some reason, the trivet 4 can be grounded at the multiple regulating surfaces 571. Therefore, compared to when the trivet is grounded at the frame portion 511, there is less change in the distance between the cooking utensil and the burner 22, and the impact on combustion performance can be reduced.

(4.2) Rear division body The rear division body 6 is a divided trivet 4 that covers the rear burner 22 among the burners 22 lined up in the front-rear direction. The rear division body 6 differs from the front division body 5 in that the portion corresponding to the burner 22 is formed in the center in the left-right direction, but is the same in that it includes a frame portion 61, multiple positioning portions 62, multiple mounting portions 63, multiple grounding portions 64, and a regulating portion 65. Therefore, overlapping descriptions will be omitted below.

The rear split body 6 has multiple positioning parts 62 and is positioned relative to the outer periphery 313 of the burner 22 at the rear. However, the positioning parts 62 of the rear split body 6 do not have to be provided. If there are no positioning parts 62, the rear split body 6 can be positioned by contacting the front end of the frame part with the rear end of the frame part 511 of the front split body 5.

(5) Effect In the gas stove 1 according to this embodiment, the trivet 4, which collectively covers at least two of the multiple burners 22, has a positioning portion 52 (62) that is positioned relative to at least one of the multiple outer circumferential portions 313.

In the gas stove 1 according to this embodiment, the trivet 4 can be positioned relative to the outer periphery 313, improving the degree of freedom in designing the outer periphery of the top plate. In addition, because the trivet 4 is positioned relative to the outer periphery 313 close to the burner 22, the positional relationship between the trivet 4 and the burner 22 can be maintained with high precision, and the installation state of the trivet 4 is unlikely to affect the combustion performance.

In addition, because the gas stove 1 according to this embodiment uses a trivet 4 (full-surface trivet) that is positioned relative to the outer periphery 313, it is also possible to use a trivet 4 (sometimes called an "individual trivet 7") that is installed for each burner 22, as shown in FIG. 7. Therefore, by using a common top plate 3, gas stoves 1 with trivets 4 according to the user's preferences can be manufactured, resulting in high manufacturability and easy inventory management.

The individual trivet 7 comprises a ring-shaped trivet frame 71 surrounding the outer periphery 313, a number of trivet claws 72 fixed to the trivet frame 71 and arranged radially, and a pair of positioning parts 73 provided on the front and rear trivet claws 72. The pair of positioning parts are inserted into the recesses 314 of the outer periphery 313, thereby positioning the individual trivet 7 relative to the outer periphery 313.

In addition, in the gas stove 1 according to this embodiment, the trivet 4 is made up of multiple segments, making it easy to handle when cleaning.

In addition, in the gas stove 1 according to this embodiment, the portion of the front divided body 5 that corresponds to the center C1 of the burner 22 is offset in either the front or rear direction from the center C2 in the front-to-rear direction of the front divided body 5, so that while a cooking utensil is placed in a position to be heated by the burner 22, it is easy to place other cooking utensils in other positions on the trivet 4.

In particular, the front split body 5 is configured so that the portion of the front split body 5 that corresponds to the center C1 of the burner 22 is located rearward of the center C2 of the front split body 5 in the fore-and-aft direction, so that in the event of incorrect installation, the rear end of the front split body 5 enters the installation area of the rear split body 6. Therefore, the rear split body 6 cannot be installed, and the user can be sure that the front split body 5 has been incorrectly installed.

In addition, the trivet 4 according to this embodiment has contact sections 56, 64 that rest on the upper surface of the top plate 3 and are made of a cushioning material, so that when the trivet 4 is installed on the top plate 3, the trivet 4 and the top plate 3 come into contact with each other, preventing noise from being generated between the components.

In addition, the positioning portion 52 (62) of the trivet 4 is the tip that is inserted into the recess 314, so the contact area between the positioning portion 52 (62) and the outer periphery 313 can be made as small as possible, and the generation of contact noise between the components can be minimized as much as possible.

In addition, the lower end of the tip portion constituting the positioning portion 52 (62) is formed in a tapered shape such that the thickness dimension decreases as it approaches the bottom end, so that the positioning portion 52 (62) can be smoothly inserted into the recess 314.

In addition, since a restricting portion is formed between adjacent grounding portions 56, bending of the portions of the frame portion 511 between the grounding portions 56 can be minimized.

<Modification>
The above embodiment is merely one of various embodiments of the present invention. The embodiment can be modified in various ways depending on the design and the like as long as the object of the present invention can be achieved. Modifications of the above embodiment will be described below.

(1) Modification 1
In the trivet 4 of the above embodiment, the grounding portions 56, 64 are attached to the frame portion 511, but in the modified example 1, the grounding portions 56, 64 are attached to the first connecting portion 512 that supports the mounting portion 53, as shown in Figure 8.

As shown in FIG. 9, the grounding parts 56, 64 in the first modification have a foot 561 along the lower end of the first connecting part 512 and a locking part 562 formed integrally with the foot 561. A groove 514 into which the locking part 562 fits is formed at the lower end of the first connecting part 512. The trivet 4 has a regulating surface 571, as in the above embodiment. The regulating surface 571 is formed by the lower end surface of the regulating part 57 provided at the lower end of the first connecting part 512 (indicated by the symbol A in FIG. 10) located between the adjacent grounding parts 56, 64.

In this way, the grounding parts 56, 64 may be provided not only on the frame part 511 but also on the first connecting part 512. Also, although not specifically shown, the grounding parts 56, 64 may be provided on the second connecting part 513.

(2) Other Modifications Modifications of the embodiment are listed below. The modifications described below can be applied in appropriate combinations.

The gas stove 1 according to the above embodiment is provided with multiple burners 22 separated into front and rear sides with respect to the center of the top plate 3 in the front-to-rear direction, but in the present invention, the multiple burners 22 do not have to be separated into front and rear sides with respect to the center of the top plate 3 in the front-to-rear direction. For example, two or more burners 22 may be arranged in the left-right direction along the center of the top plate 3 in the front-to-rear direction.

The top plate 3 in the above embodiment is made of a metal plate in which the cooking section 31, exhaust section 32, and outer periphery 33 are integrally formed, but in the present invention, the cooking section 31 may be made of glass, and the outer periphery 33 and exhaust section 32 may be made of metal, and there are no particular restrictions on the materials.

In the gas stove 1 according to the above embodiment, the positioning parts 52 and 62 are formed by the tip parts, and are inserted into the recesses 314 in the outer periphery 313 to achieve positioning relative to the outer periphery 313 of the trivet 4. However, in the present invention, the positioning parts 52 and 62 may be formed by a ring-shaped frame material that surrounds the periphery of the outer periphery 313.

The front split body 5 according to the above embodiment includes a first positioning portion 521 and a second positioning portion 522 that are spaced apart in the front-rear direction, but it may include only one of the first positioning portion 521 and the second positioning portion 522. In this case, the outer peripheral portion 313 may have a structure that includes only one recess 314. Furthermore, the front split body 5 may include three or more positioning portions as the multiple positioning portions.

In the front split body 5 according to the above embodiment, the first positioning portion 521 and the second positioning portion 522 are positioned apart in the front-rear direction with respect to one burner 22, but they may be positioned apart in the left-right direction, for example. In addition, the first positioning portion 521 and the second positioning portion 522 are positioned on a straight line passing through the center of the burner 22, but the first positioning portion 521 and the second positioning portion 522 may be positioned at a position where the angle between the straight line connecting the first positioning portion 521 and the center of the burner 22 and the straight line connecting the second positioning portion 522 and the center of the burner 22 is 90°.

The trivet 4 in the above embodiment is configured as a full trivet that covers the entire surface of the cooking area 31, but in the present invention, the trivet may be configured so that the rear divided body 6 corresponds only to the periphery of the rear burner 22, and is located behind the center of the top plate 3 in the front-to-rear direction and does not cover the areas on both sides of the rear burner 22 in the left-to-right direction. The trivet 4 may also be configured as a combination of the front divided body 5 and individual trivets 7.

The trivet 4 according to the above embodiment is configured with a divided body that is divided in the front-to-rear direction, but it may also be configured with a divided body that is divided in the left-to-right direction, for example. In this case, each divided body is formed, for example, in a generally rectangular shape in plan view with its longitudinal direction in the front-to-rear direction.

The top plate 3 according to the above embodiment has an outer peripheral edge 33 that rises from the cooking area 31, but the outer peripheral edge 33 does not have to rise from the cooking area 31. If the cooking area 31 is made of a glass plate, the outer peripheral edge 33 may be made of a frame material that protects the edge of the glass plate, and in this case, the upper end of the frame material may be formed at the same height as the upper end of the edge of the glass plate.

In the trivet 4 according to the above embodiment, the grounding portions 56, 64 are provided partially in the circumferential direction of the frame portion 511, but may be provided, for example, over the entire circumferential length of the frame portion 511.

The front split body 5 in the above embodiment is configured to cover two burners, but the front split body 5 may be configured to be split in the left and right directions.

In the above embodiment, the position corresponding to the center C1 of the burner 22 of the front divided body 5 is located behind the center C2 of the front divided body 5 in the front-to-rear direction, but the position corresponding to the center C1 of the burner 22 may be located forward of the center C2 of the front divided body 5 in the front-to-rear direction. In this case, when a cooking utensil is placed directly above the front burner 22, it is advantageous to be able to place other cooking utensils behind the cooking utensil. In this case, even if the front divided body 5 is installed incorrectly, a gap is created between the rear end of the front divided body 5 and the rear divided body 6, so the user can easily know that the trivet 4 is installed incorrectly.

In the gas stove 1 according to this embodiment, the positioning portion 52 is formed on both the front divided body 5 and the rear divided body 6, but in the present invention, it is sufficient that the positioning portion 52 is formed on at least one of the multiple divided bodies. Also, when multiple burners 22 are covered in one divided body, the positioning portion 52 only needs to be positioned with respect to the outer periphery 313 corresponding to at least one burner 22.

In this specification, expressions that include "approximately", such as "approximately parallel" or "approximately perpendicular", may be used. For example, "approximately parallel" means that the object is essentially "parallel", and does not only mean a strictly "parallel" state, but also includes an error of a few degrees. The same applies to other expressions that include "approximately".

Furthermore, in this specification, expressions that are differentiated by the presence or absence of "part...", such as "end" and "end", are used. For example, "end" means the end part of an object, while "end" means an area with a certain range that includes the "end". Any point that is within a certain range that includes the end is considered to be an "end". The same applies to other expressions that include "part...".
