MODE FOR CARRYING OUT THE INVENTION

[0017] [[ID=2二十二]] <Embodiment> Hereinafter, the gas stove 1 according to the present embodiment will be described in detail.

[0018] (1) Overall The gas stove 1 is a stove that uses gas as fuel. The gas stove 1 according to the present embodiment is a built-in stove in which the device main body 2 is dropped into an opening formed in the worktop of the kitchen counter. However, in the present invention, it may be a table stove that is placed on an installation surface (for example, a table, a stove stand, etc.) and used. [[ID=三十三]]

[0019] The gas stove 1 is a gas stove with a grill in the present embodiment. According to the gas stove with a grill, the cooked food stored in the grill cabinet can be grilled. However, the gas stove 1 according to the present invention does not necessarily have to have a grill function. As the gas stove 1, instead of the grill function, for example, it may have a multi-grill having a range function, an oven function, or a rice cooker function, or it may have any one of a range, an oven, or a rice cooker. [[ID=3七十七]]

[0020] In the following, for the sake of explanation, directions will be defined based on the usage of the gas stove 1. That is, assuming a usage scenario where the user faces the gas stove 1 directly while cooking, the "left-right direction" will be defined as shown in Figure 1. Furthermore, the direction from the gas stove 1 toward the user and along the horizontal plane will be defined as the "forward direction," the opposite direction as the "backward direction," and the two directions parallel to the forward and back directions will be defined as the "front-back direction." In addition, the direction perpendicular to the installation surface (the top surface of the worktop) will be defined as the "up-down direction." However, these definitions of directions are not intended to limit the usage scenarios of the gas stove 1 according to the present invention.

[0021] As shown in Figure 1, the gas stove 1 comprises a main unit 2 having multiple (in this case, three) burners 22, a top plate 3, and a trivet 4.

[0022] (2) Main unit of the device The main body of the appliance 2 constitutes the main component of the gas stove 1. The main body of the appliance 2 comprises a housing 21 and a plurality of appliances 22, 23. In this embodiment, the gas stove 1 has a plurality of burners 22 and a grill device 23 as the plurality of appliances 22, 23.

[0023] (2.1) Enclosure The housing 21 is a box within the main unit 2 that houses the equipment. The housing 21 is formed in a rectangular parallelepiped shape and has an opening (not shown) on its top surface. As shown in Figure 1, the front of the housing 21 has an opening 211 for passing through the grill door 231 and an opening 212 for passing through the control devices 24 that ignite / extinguish and adjust the heat output of each piece of equipment.

[0024] (2.2) Burner The burner 22 heats the cooking utensil (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. Multiple burners 22 are arranged apart from each other within the housing 21. The appliance body 2 has multiple burners 22, consisting of two burners 22 located in front of the center in the front-to-back direction of the top plate 3, and one burner 22 located behind the said center. However, the appliance body 2 may have two burners 22 located behind the center in the front-to-back direction of the top plate 3 that are separated in the left-to-right direction (i.e., the appliance body 2 may have four burners 22).

[0025] Here, "cooking utensils" as used in this specification refers to tools used in cooking. Examples of cooking utensils include cooking containers such as pots, earthenware pots, frying pans, and kettles, as well as grilling racks, heating plates, takoyaki plates, hot sandwich plates, and waffle makers.

[0026] As shown in Figure 2, the burner 22 comprises a burner body 221, a burner cap 222, an ignition plug 224, and a temperature sensor 225. The burner body 221 is the burner 22 The main component is the burner body 221, to which a gas supply passage (not shown) leading to a fuel gas supply source such as city gas or LP gas is connected. 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 close the opening.

[0027] The burner cap 222 is a component that rests on the upper end surface of the burner body 221, and forms a plurality of flame ports 226 with 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.

[0028] The temperature sensor 225 is used to measure the temperature of the cookware placed on the trivet 4 and to detect the temperature of the food being cooked inside the cookware. The temperature sensor 225 is located in the center of the burner 22 when viewed from above (sometimes referred to as a plan view). In this specification, "center of the burner 22" means the center of the portion that protrudes above the upper surface of the top plate 3 in a plan view, and in this embodiment, it 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 in a plan view.

[0029] 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 as to be able to move vertically relative to the burner cap 222 and is elastically displaceable. Therefore, when a cookware is placed on the trivet 4, the upper end surface of the temperature sensor 225 descends while in contact with the cookware, and at this time it elastically contacts the cookware. As a result of the upper end surface of the temperature sensor 225 coming into contact with the cookware, the temperature of the cookware can be measured by processing the electrical signal generated by the temperature sensor 225 with a controller (not shown). As a result, the temperature of the food being cooked in the cookware can be detected.

[0030] (2.3) Grilling device The grilling device 23 is a device capable of grilling food placed in a grilling chamber (not shown). The grilling device 23 comprises a grilling chamber (not shown) having an opening at the front, and a grilling door 231 that can open and close the opening of the grilling chamber. The grilling door 231 is attached to the grilling chamber via a support mechanism (not shown) so as to be movable parallel to the front and rear directions.

[0031] (3) Top plate The top plate 3 is the uppermost plate of the gas stove 1. As shown in Figure 1, the top plate 3 is formed in a substantially rectangular shape. The top plate 3 comprises a cooking section 31, an exhaust section 32, and an outer peripheral edge 33. In this embodiment, the top plate 3 is made of a metal plate in which the cooking section 31, exhaust section 32, and outer peripheral edge 33 are integrally formed. Examples of metal plates include aluminum, enamel, and fluorine-coated steel plates. However, in this invention, the top plate 3 is not limited to a metal plate and may be made of glass, for example.

[0032] (3.1) Cooking section The cooking section 31 is an area for cooking and is capable of receiving liquids (e.g., boil-overs, spills, etc.). A trivet 4 is attached to the cooking section 31, and cooking utensils are placed on the trivet 4. As shown in Figure 2, the cooking section 31 comprises a flat receiving section 311 located below the exhaust section 32 and the outer peripheral edge 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 is They let me in.

[0033] The outer periphery 313 is formed around the burner insertion hole 312 and prevents liquid from entering the burner insertion hole 312. The outer periphery 313 is raised from the receiving portion 311 and can block the liquid received by the receiving portion 311 from flowing towards the burner insertion hole 312. The outer periphery 313 may be formed integrally with the receiving portion 311, or it may be formed by attaching a separate member such as a burner ring. In this embodiment, the outer periphery 313 is formed integrally with the receiving portion 311 by drawing.

[0034] In this embodiment, as described above, the outer peripheral portion 313 is integrally formed with respect to the receiving portion 311, and the structure makes it easy to wipe off any liquids adhering to the outer peripheral portion 313, so the burner insertion hole 312 is exposed. However, if the outer peripheral portion 313 is composed of a burner ring, the burner insertion hole 312 may be covered by a cover.

[0035] As shown in Figure 1, the top plate 3 is attached to the housing 21 of the main unit 2 of the equipment so as to rest on the upper end of the housing 21. When the top plate 3 is attached to the main unit 2 of the equipment, the upper end of the burner 22 is passed through the burner insertion hole 312 and protrudes above the upper surface of the outer circumference 313.

[0036] In addition to the function of blocking the liquid as described above, the outer periphery 313 also has the function of positioning the mounting position of the trivet 4 on the top plate 3 by holding the positioning parts 52 and 62 of the trivet 4. The positioning of the trivet 4 by the outer periphery 313 may be achieved by contact with the side surface of the outer periphery 313 (the surface rising from the receiving part 311), but in this embodiment, it is achieved by inserting the positioning parts 52 and 62 of the trivet 4 into the recess 314 (Figure 2) formed in the outer periphery 313.

[0037] As shown in Figure 2, the recesses 314 are formed at two locations on the outer circumference 313, at the front and rear ends. The recess 314 at the front end opens in the forward and upward directions. The recess 314 at the rear end opens in the rear and upward directions. Therefore, when attaching the trivet 4 to the top plate 3, when the positioning parts 52 and 62 of the trivet 4 are inserted into the recesses 314 from top to bottom, the positioning parts 52 (62) fit into the recesses 314, as shown in Figure 3.

[0038] (3.2) Exhaust section The exhaust section 32 is a flat plate-shaped part in which an exhaust port is formed to release exhaust from inside the grill compartment. As shown in Figure 1, the exhaust section 32 is located behind the cooking section 31. An exhaust port cover 321 is removablely attached to the exhaust port.

[0039] (3.3) Peripheral edge The outer peripheral edge 33 surrounds the outer periphery of the cooking section 31 and is the portion that rises from the outer edge of the cooking section 31. As shown in Figure 3(A), the outer peripheral edge 33 has an upright portion 331 and a top portion 332. The upright portion 331 rises from the outer edge of the receiving section 311 (i.e., the outer edge of the cooking section 31). The upright portion 331 is inclined relative to the receiving section 311 so that it goes upward as it goes outward from the edge of the receiving section 311. The top portion 332 protrudes along the horizontal plane from the upper end of the upright 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 edges 33 in the left and right directions and the front peripheral edge 33, and to the exhaust section 32 (Figure 1) for the rear peripheral edge 33.

[0040] (4) Trivet The trivet 4 is removably attached to the top plate 3 and supports cookware on the burner 22. The trivet 4 supports at least two of the multiple burners 22. It is configured to cover the two burners together, and in this case, it covers the three burners 22 together. In this embodiment, the trivet 4 is a full-surface trivet that covers the entire surface of the cooking section 31.

[0041] Trivet 4 is made of metal. Examples of metals that make up trivet 4 include enamel and stainless steel.

[0042] As shown in Figure 4, the trivet 4 is composed of multiple (in this case, two) divisible sections 5 and 6. Each of the sections 5 and 6 is formed in a roughly rectangular shape in plan view, with its longitudinal direction in the left-right direction. Hereinafter, the section that covers the burner 22 located in front of the center of the top plate 3 in the front-to-back direction will be defined as the "front section 5," and the section that covers the burner 22 located behind the center of the top plate 3 in the front-to-back direction will be defined as the "rear section 6."

[0043] (4.1)Anterior split body The front split section 5 is a divided trivet 4 that covers the front burner 22 among the burners 22 arranged in the front-to-back direction. Therefore, as shown in Figure 1, the front split section 5 according to this embodiment covers both of the left and right burners 22 located at the front.

[0044] Here, as shown in Figure 5(A), in the front split body 5, the position corresponding to the center C1 of the burner 22 is offset in either the front-rear direction from the center C2 in the front-rear direction of the front split body 5. Specifically, in this embodiment, the position corresponding to the center C1 of the burner 22 in the front split body 5 is located rearward from the center C2 in the front-rear direction of the front split body 5.

[0045] Therefore, in the gas stove 1 according to this embodiment, even if a certain distance or more is secured from the front end of the top plate 3 in order to keep the front burner 22 of the multiple burners 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, it is possible to prevent liquid from reaching the user if it boils over from the cooking utensil, and to suppress the effects of the flame and heat from the burner 22.

[0046] Here, Figure 5(A) shows a plan view of the front split body 5 in the correct orientation, and Figure 5(B) shows a plan view of the front split body 5 installed in the opposite orientation. In this way, if the position of the front split body 5 corresponding to the center C1 of the burner 22 is shifted in either the front-to-back direction relative to the front-to-back center C2 of the front split body 5, there is an advantage in that when a cooking utensil is placed directly above the burner 22, it is easier to place other cooking utensils at other positions on the trivet 4.

[0047] Furthermore, if the front section 5 is installed in the wrong direction (sometimes referred to as "incorrect installation"), as shown in Figure 5(B), a portion of the front section 5 will enter the installation area of ​​the rear section 6. As a result, the user will be unable to install the rear section 6, and will be able to reliably detect the incorrect installation of the front section 5.

[0048] As shown in Figure 4, the front split body 5 comprises a frame portion 51, a plurality of positioning portions 52, a plurality of mounting portions 53, and a plurality of ground contact portions 56.

[0049] (4.1.1) Frame section The frame portion 51 is the skeletal part that connects the positioning portion 52 and the multiple mounting portions 53. The frame portion 51 comprises 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.

[0050] The frame portion 511 is formed in a roughly rectangular shape when viewed from above. The frame portion 511 surrounds a pair of left and right burners 22 located at the front of the plurality of burners 22. The lower surface of the frame portion 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 edge of the frame portion 511 follows the front outer edge 33 of the outer edge 33 of the top plate 3, both left and right edges of the frame portion 511 follow the left and right outer edges 33 of the outer edge 33 of the top plate 3, and the rear edge of the frame portion 511 follows the center of the cooking section 31 in the front-to-back direction.

[0051] The cross-sectional shape of the frame portion 511 is not particularly limited, but examples include a vertically elongated rectangle, a circular shape, a rounded-corner rectangle, a flat plate shape, a pipe shape, etc. In this case, it is formed in a rounded-corner rectangle shape (4 mm wide, 10 mm long).

[0052] The first connecting portion 512 rises from the frame portion 511 and supports the multiple mounting portions 53. Each first connecting portion 512 is formed in a plate shape and is fixed to the frame portion 511 by welding. Note that the fixing of the frame portion 511 and the first connecting portion 512 is not limited to welding, but may also be achieved by fitting, machining, screwing, etc.

[0053] The second connecting portion 513 connects the positioning portion 52 and the frame portion 511, allowing the positioning portion 52, which is positioned relative to the outer circumference 313, to position the frame portion 511 in the correct position. The second connecting portion 513 extends from the frame portion 511 toward the outer circumference 313 and fixes the positioning portion 52 to the frame portion 511.

[0054] (4.1.2) Positioning section The positioning portion 52 is the part that is positioned relative to the outer circumference 313 of the top plate 3. As shown in Figure 3, the positioning portion 52 consists of a tip that is inserted into a recess 314 of the outer circumference 313. The front split body 5 has two positioning portions 52 for one burner 22. These two positioning portions 52 are located on a straight line passing through the center of the burner 22 and face each other. Here, the positioning portion 52 that is inserted into the front recess 314 is called the "first positioning portion 521", and the positioning portion 52 that is inserted into the rear recess 314 is called the "second positioning portion 522". When the first positioning portion 521 is inserted into the front recess 314 and the second positioning portion 522 is inserted into the rear recess 314, the trivet 4 is positioned in both the front-to-back direction and the left-to-right direction.

[0055] Furthermore, as shown in Figure 3(B), each positioning portion 52 is formed in a tapered shape such that its thickness decreases as it approaches the lower end. In this embodiment, only the lower end of the positioning portion 52 is formed in a tapered shape, but for example, it may be formed in a tapered shape from the center in the vertical direction toward the lower end, or from the upper end toward the lower end. Because the positioning portion 52 is formed in a tapered shape, it can be smoothly inserted into the recess 314.

[0056] (4.1.3) Mounting section The mounting section 53 is the part on which cooking utensils are placed. The upper end surfaces of the multiple mounting sections 53 are located on the same plane. As shown in Figure 4, the mounting section 53 comprises multiple claw sections 54 arranged radially from the center of the burner 22, and auxiliary sections 55 that form the mounting section 53 other than the claw sections 54.

[0057] As shown in Figure 3(A), the claw portion 54 is formed in a tapered shape such that the vertical width dimension decreases towards the tip on the central side of the burner 22. As shown in Figure 4, the auxiliary portion 55 is composed of a combination of multiple vertical members 551 extending in the front-to-back direction and multiple horizontal members 552 extending in the left-to-right direction. The multiple vertical members 551 and the multiple horizontal members 552 are arranged, for example, in a grid pattern. It is formed in this way.

[0058] (4.1.4) Grounding part The multiple contact points 56 are the parts of the trivet 4 that rest on the upper surface of the top plate 3 (more specifically, the receiving portion 311). The contact points 56 are composed of cushioning members. The cushioning members suppress the generation of contact noise between the members when the trivet 4 comes into contact with the top plate 3. The cushioning members are preferably made of a material softer than the metal that constitutes the frame portion 51, and examples include elastomer, soft synthetic resin, hard synthetic resin, resin foam, wood, cloth, etc.

[0059] The ground contact portion 56 is provided on the frame portion 51. Multiple ground contact portions 56 are attached at intervals along the frame portion 511. In this embodiment, multiple ground contact portions 56 are attached to the frame portion 511. The attachment of the ground contact portions 56 to the frame portion 511 can be achieved, for example, by adhesive, fitting, welding, two-color molding, screw fastening, pin fastening, riveting, snap-fit ​​structure, wrapping, etc.

[0060] When no cooking utensils are placed on the trivet 4, the contact portion 56 rests on the receiving portion 311, and a gap is formed between the lower end surface excluding the contact portion 56 and the upper surface of the top plate 3. Therefore, when installing the trivet 4 on the top plate 3 or placing cooking utensils on the trivet 4, the generation of contact noise between the trivet 4 and the top plate 3 is suppressed.

[0061] Here, the first connecting portion 512 that supports the mounting portion 53 is connected to the portion of the frame portion 511 between adjacent ground contact portions 56. Therefore, when a cooking utensil is placed on the mounting portion 53 (for example, the claw portion 54), the load is applied to the frame portion 511 via the first connecting portion 512, and the portion of the frame portion 511 between the ground contact portions 56 may flex. When the frame portion 511 flexes, the mounting portion 53 moves closer to the burner 22, which affects the combustion performance.

[0062] Therefore, in the trivet 4 according to this embodiment, as shown in Figure 6, a regulating surface 571 is formed located between the lower surface of the ground contact portion 56 and the lower surface of the frame portion 511. Figure 6 is an explanatory diagram comparing the height positions of the cross-section of the ground contact portion 56 and the cross-sections of the frame portion 511 and the regulating surface 571 in order to explain the height relationship between the two.

[0063] As shown in Figure 6, the dimension L2 between the regulating surface 571 and the lower surface of the ground contact portion 56 is smaller than the dimension L1 between the lower surface of the frame portion 511 and the lower surface of the ground contact portion 56. Therefore, because the regulating surface 571 is located between the lower surface of the ground contact portion 56 and the lower surface of the frame portion 511, even if the portion of the frame portion 511 between the ground contact portions 56 flexes, the regulating surface 571 contacts the top plate 3, preventing the frame portion 511 from flexing any further. As a result, when installing the trivet 4, the flexing of the portion of the frame portion 511 between the ground contact portions 56 can be minimized while suppressing the generation of contact noise between components.

[0064] As shown in Figure 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. By being provided on the first connecting portion 512 and the second connecting portion 513, the restricting portion 57 can be positioned between adjacent ground contact portions 56. In Figure 6, it is shown 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, but the restricting portion 57 is also provided on the lower end of the first connecting portion 512 that supports the auxiliary portion 55.

[0065] Furthermore, the restricting portion 57 is not limited to the first connecting portion 512 and / or the second connecting portion 513, but may also be provided on the frame portion 511, for example. Also, although the restricting surface 571 is formed in a planar shape, There are no particular restrictions on the shape; for example, it may be arc-shaped, spherical, linear, or point-shaped.

[0066] Because the regulating surfaces 571 are provided in multiple locations, even if, for example, the user removes and loses the grounding part 56 for some reason, the trivet 4 can still be grounded by multiple regulating surfaces 571. Therefore, compared to grounding at the frame part 511, the distance between the cooking appliance and the burner 22 changes less, and the impact on combustion performance can be reduced.

[0067] (4.2) Posterior split body The rear split body 6 is a divided trivet 4 that covers the burner 22 located at the rear of the burners 22 arranged in the front-to-back direction. The rear split body 6 differs from the front split body 5 in that the portion corresponding to the burner 22 is formed in the center in the left-to-right direction, but it is the same in that it has a frame portion 61, multiple positioning portions 62, multiple mounting portions 63, multiple grounding portions 64 and regulating portions 65. Therefore, redundant explanations will be omitted below.

[0068] The rear section 6 has a plurality of positioning parts 62 and is positioned relative to the outer circumference 313 of the burner 22 located at the rear. However, the positioning parts 62 of the rear section 6 are not required. If there are no positioning parts 62, the rear section 6 can be positioned by bringing the front end of the frame portion into contact with the rear end of the frame portion 511 of the front section 5.

[0069] (5) Effects In this embodiment of the gas stove 1, the trivet 4, which covers at least two of the multiple burners 22 together, has a positioning portion 52 (62) that is positioned relative to at least one of the multiple outer peripheral portions 313.

[0070] In the gas stove 1 according to this embodiment, the trivet 4 can be positioned relative to the outer periphery 313, thereby improving the design flexibility of the outer periphery of the top plate. Furthermore, since the trivet 4 is positioned relative to the outer periphery 313 that is 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 does not significantly affect the combustion performance.

[0071] Furthermore, in the gas stove 1 according to this embodiment, since a trivet 4 (full-surface trivet) is positioned relative to the outer circumference 313, it is also possible to use trivets 4 (sometimes referred to as "individual trivets 7") installed for each burner 22, as shown in Figure 7. Therefore, since a common top plate 3 can be used to manufacture gas stoves 1 with trivets 4 according to the user's preference, manufacturability is high and inventory management is easy.

[0072] Each individual trivet 7 comprises a ring-shaped trivet frame 71 surrounding the outer periphery 313, a plurality 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 recesses 314 of the outer periphery 313, thereby positioning the individual trivet 7 relative to the outer periphery 313.

[0073] Furthermore, in the gas stove 1 according to this embodiment, the trivet 4 is composed of multiple separate parts, making it easier to handle during cleaning.

[0074] Furthermore, in the gas stove 1 according to this embodiment, the portion of the front split body 5 corresponding to the center C1 of the burner 22 is offset in either the front-to-back direction relative to the front-to-back center C2 of the front split body 5. Therefore, even when placing a cooking utensil 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.

[0075] In particular, the front split body 5 has a portion corresponding to the central C1 of the burner 22 of the front split body 5, which is the front Since the front section 5 is configured to be positioned behind the central point C2 in the front-rear direction, in the event of incorrect installation, the rear end of the front section 5 will enter the installation area of ​​the rear section 6. Therefore, the rear section 6 cannot be installed, and the user can be certain that the front section 5 has been incorrectly installed.

[0076] Furthermore, in this embodiment, the trivet 4 has contact points 56 and 64 that rest on the upper surface of the top plate 3, which are made of cushioning material. Therefore, when installing the trivet 4 on the top plate 3, it is possible to suppress the generation of contact noise between the trivet 4 and the top plate 3.

[0077] Furthermore, since the positioning portion 52(62) of the trivet 4 is the tip portion that is inserted into the recess 314, the contact area between the positioning portion 52(62) and the outer circumference 313 can be made as small as possible, and the generation of contact noise between the components can be suppressed as much as possible.

[0078] Furthermore, 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 lower end, allowing the positioning portion 52(62) to be smoothly inserted into the recess 314.

[0079] Furthermore, since a restricting portion is formed between adjacent ground contact portions 56, the deflection of the portion of the frame portion 511 between the ground contact portions 56 can be minimized.

[0080] <Variation> The above embodiments are merely one of many embodiments of the present invention. The embodiments can be modified in various ways depending on the design, etc., as long as they achieve the objectives of the present invention. Modifications of the above embodiments will be described below.

[0081] (1) Variation 1 In the above embodiment, the trivet 4 has its ground contact portions 56 and 64 attached to the frame portion 511. However, in the modified example 1, the ground contact portions 56 and 64 are attached to the first connecting portion 512 that supports the mounting portion 53, as shown in Figure 8.

[0082] The ground contact portions 56 and 64 in the modified example 1, as shown in Figure 9, include a foot portion 561 along the lower end of the first connecting portion 512 and a locking portion 562 integrally formed with the foot portion 561. A groove 514 into which the locking portion 562 fits is formed at the lower end of the first connecting portion 512. The trivet 4 also has a regulating surface 571, similar to the above embodiment. The regulating surface 571 is composed of the lower end surface of a regulating portion 57 provided at the lower end of the first connecting portion 512 (indicated by reference numeral A in Figure 10), which is located between adjacent ground contact portions 56 and 64.

[0083] Thus, the ground contact portions 56 and 64 may be provided not only on the frame portion 511 but also on the first connecting portion 512. Furthermore, although not specifically shown in the figures, the ground contact portions 56 and 64 may also be provided on the second connecting portion 513.

[0084] (2) Other variations The following lists some modifications of the embodiment. The modifications described below can be combined and applied as appropriate.

[0085] In the gas stove 1 according to the above embodiment, the top plate 3 is equipped with multiple burners 22 separated into front and rear sides with respect to the center in the front-to-back direction. However, in the present invention, the multiple burners 22 do not have to be separated into front and rear sides with respect to the center in the front-to-back direction of the top plate 3. For example, two or more burners 22 are arranged in the left-to-right direction along the center in the front-to-back direction of the top plate 3. It may be placed.

[0086] In the above embodiment, the top plate 3 is made of a metal plate in which the cooking section 31, exhaust section 32, and outer peripheral edge 33 are integrally formed. However, in the present invention, the cooking section 31 may be made of glass, and the outer peripheral edge 33 and exhaust section 32 may be made of metal, and there are no particular restrictions on the material.

[0087] In the gas stove 1 according to the above embodiment, the positioning parts 52 and 62 are composed of tip portions that are inserted into recesses 314 of the outer circumference 313 to achieve positioning of the trivet 4 relative to the outer circumference 313. However, in the present invention, the positioning parts 52 and 62 may be composed of a ring-shaped frame material that surrounds the outer circumference 313.

[0088] The front split body 5 according to the above embodiment includes a first positioning portion 521 and a second positioning portion 522 that are separated in the front-rear direction, but it may also have 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 have three or more positioning portions as multiple positioning portions.

[0089] In the above embodiment, the front split body 5 had the first positioning part 521 and the second positioning part 522 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. Also, although the first positioning part 521 and the second positioning part 522 were positioned on a straight line passing through the center of the burner 22, they may be positioned such that the angle between the straight line connecting the first positioning part 521 and the center of the burner 22 and the straight line connecting the second positioning part 522 and the center of the burner 22 is 90°.

[0090] In the above embodiment, the trivet 4 is composed of a full-surface trivet that covers the entire surface of the cooking section 31. However, in the present invention, the rear divided body 6 may correspond only to the area around the rear burner 22, and the trivet may be composed of a part that is behind the center of the top plate 3 in the front-to-back direction and does not cover the areas on both sides in the left-to-right direction of the rear burner 22. Alternatively, the trivet 4 may be composed of a combination of the front divided body 5 and individual trivets 7.

[0091] The trivet 4 in the above embodiment is composed of divided sections that divide in the front-to-back direction, but it may also be composed of divided sections that divide in the left-to-right direction, for example. In this case, each divided section is formed in a substantially rectangular shape in plan view, for example, having its longitudinal direction in the front-to-back direction.

[0092] In the above embodiment, the top plate 3 had an outer peripheral edge 33 that rose from the cooking section 31, but the outer peripheral edge 33 does not have to rise from the cooking section 31. If the cooking section 31 is made of a glass plate, the outer peripheral edge 33 may be made of a frame material that protects the end face of the glass plate, in which case the upper end of the frame material may be formed at the same height as the upper end of the end face of the glass plate.

[0093] In the above embodiment, the trivet 4 has ground contact portions 56 and 64 partially provided in the circumferential direction of the frame portion 511, but for example, they may be provided along the entire length of the frame portion 511 in the circumferential direction.

[0094] In the above embodiment, the front split body 5 is configured to cover two burners, but the front split body 5 may also be configured to be separable in the left-right direction.

[0095] In the above embodiment, the front split body 5 has a position corresponding to the center C1 of the burner 22 located behind the center C2 in the front-rear direction of the front split body 5. However, the position corresponding to the center C1 of the burner 22 may be located in front of the center C2 in the front-rear direction of the front split body 5. In this case, the front When a cooking appliance is placed directly above the side burner 22, there is an advantage in that other cooking appliances can be easily placed behind the cooking appliance. In this case, even if the front split section 5 is installed incorrectly, a gap will be created between the rear end of the front split section 5 and the rear split section 6, so the user can easily find out if the trivet 4 has been installed incorrectly.

[0096] 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 if it is formed on at least one of the multiple divided bodies. Furthermore, if a single divided body covers multiple burners 22, the positioning portion 52 only needs to be positioned relative to the outer peripheral portion 313 corresponding to at least one burner 22.

[0097] In this specification, expressions containing "approximately" or "approximately perpendicular" may be used. For example, "approximately parallel" means substantially parallel, and includes an error of a few degrees, not just strictly parallel. The same applies to other expressions containing "approximately".

[0098] Furthermore, in this specification, expressions such as "end" and "end" are distinguished by the presence or absence of "...part". For example, "end" means the very end of an object, while "end" means a certain range that includes the "end". Any point that is within a certain range that includes the "end" is considered an "end". The same applies to other expressions that include "...part". [Explanation of Symbols]
