DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] <Embodiment> The gas stove 1 according to this embodiment will be described in detail below.

[0012] (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, it may be a table stove that is used by placing it on an installation surface (for example, a table, a stove stand, etc.).

[0013] 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, an oven function, and a rice cooking function, or may have any of a range, an oven, or a rice cooker.

[0014] For ease of explanation, the directions are defined below based on the manner in which the gas stove 1 is used. That is, 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 "front direction," the opposite direction as the "rear direction," and the two directions parallel to the front and rear 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, the definitions of these directions are not intended to limit the manner in which the gas stove 1 according to the present invention is used.

[0015] As shown in FIG. 1, the gas stove 1 includes an appliance body 2 having a plurality of (three in this example) burners 22, a top plate 3, and a trivet 4.

[0016] (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.

[0017] (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.

[0018] (2.2) Burner The burners 22 heat the cooking utensils placed on the trivet 4. The burners 22 are Bunsen burners that receive a supply of gas containing gas and perform premixed combustion. The burners 22 are arranged apart from one another 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 cooking section 31 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, separated in the left-right direction (i.e., the device body 2 may have four burners 22).

[0019] Here, the term "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 grills, heating plates, takoyaki plates, hot sandwich plates, waffle makers, and the like.

[0020] 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 body of the burner 22. A gas supply path (not shown) leading 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 path 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.

[0021] The burner cap 222 is a component placed on the upper end surface of the burner body 221, and forms a plurality of 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.

[0022] 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 at the center of the burner 22 when viewed from above (sometimes called a plan view). In this specification, "the center of the burner 22" means the center in a plan 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 at the center of the burner cap 222 when viewed from above.

[0023] The upper end of the temperature sensor 225 protrudes upward from the upper end surface of the burner cap 222. The temperature sensor 225 can move elastically downward relative to the upper surface of the burner cap 222, based on the position where it protrudes from the upper end surface of the burner cap 222. 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. As a result of the upper end surface of the temperature sensor 225 contacting the cooking utensil, the temperature of the cooking utensil can be measured by processing the electrical signal generated by the temperature sensor 225 by a controller (not shown). As a result, the temperature of the food contained in the cooking utensil can be detected.

[0024] (2.3) Grilling equipment Grill device 23 is a device that can grill food stored in a grill chamber (not shown). As shown in Fig. 1, 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. 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.

[0025] (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 configured from a metal plate in which the cooking section 31, the exhaust section 32, and the outer peripheral edge section 33 are integrally formed. There are no particular limitations on the metal plate, and examples thereof include aluminum, stainless steel, enamel, and fluorine-coated steel plate.

[0026] (3.1) Cooking section Cooking section 31 is an area for cooking and is an area that can receive liquid (for example, boiling over, spillage, etc.). A trivet 4 is attached to cooking section 31, and cooking utensils are placed on trivet 4. As shown in Fig. 2, cooking section 31 is equipped with a flat receiving section 311 located below exhaust section 32 and outer peripheral edge section 33, a plurality of outer peripheral sections 313 protruding from receiving section 311, and a burner insertion hole 312 formed in the center of each outer peripheral section 313. Burner insertion hole 312 penetrates top plate 3, and an upper end of burner 22 passes through it.

[0027] The outer circumferential portion 313 has a dam portion formed around the burner insertion hole 312, and prevents liquid from entering the burner insertion hole 312. The outer circumferential portion 313 protrudes from the receiving portion 311, and the dam portion can block the liquid received by the receiving portion 311 from flowing toward the burner insertion hole 312. The outer circumferential 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 circumferential portion 313 is formed integrally with the receiving portion 311 by applying a drawing process.

[0028] In this embodiment, as described above, the outer peripheral portion 313 is formed integrally with the receiving portion 311, and the structure is such that liquids and the like 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 composed of a burner ring, for example, the burner insertion hole 312 may be covered with a cover.

[0029] 1, the top plate 3 is attached to the housing 21 so as to rest on the upper end of the housing 21 of the device body 2. When the top plate 3 is attached to the device body 2, the upper end of the burner 22 is inserted into the burner insertion hole 312 and protrudes above the upper surface of the outer circumferential portion 313.

[0030] In addition to the function of blocking liquid as described above, the outer periphery 313 also has the function of positioning the trivet 4 relative to the top plate 3 by holding the positioning portion 571 of the trivet 4. The positioning of the trivet 4 by the outer periphery 313 may be achieved by contact with a dam portion (a surface rising from the receiving portion 311) of the outer periphery 313, but in this embodiment, it is achieved by inserting the positioning portion 571 of the trivet 4 into a recess 314 (FIG. 2) formed in the outer periphery 313.

[0031] As shown in Fig. 2, the recesses 314 are formed in two places, at the front and rear ends 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, if the positioning portion 571 of the trivet 4 is inserted from top to bottom into the recess 314, the positioning portion 571 will fit into the recess 314 as shown in Fig. 3.

[0032] (3.2) Exhaust section The exhaust section 32 is a flat plate-shaped section in which an exhaust port for exhausting the exhaust air from inside the grill chamber is formed. As shown in Fig. 1, the exhaust section 32 is provided behind the cooking section 31. An exhaust port cover 321 is removably attached to the exhaust port.

[0033] (3.3) Outer periphery The outer peripheral edge 33 surrounds the outer periphery of the cooking section 31 and is a portion rising from the outer edge of the cooking section 31. As shown in FIG. 3(A), 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 move upward as it moves 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-right outer side and the front outer peripheral edge 33, and are connected to the exhaust section 32 (FIG. 1) for the rear outer peripheral edge 33.

[0034] (4) Trivet The trivet 4 is removably attached to the top plate 3 and supports cooking utensils on the burners 22. As shown in Fig. 1, the trivet 4 is configured to collectively cover at least two of the multiple burners 22, and in this embodiment, it collectively covers three burners 22. In this embodiment, the trivet 4 is configured as a full trivet that covers the entire surface of the cooking area 31.

[0035] The trivet 4 is made of metal. Examples of metals that can be used to make the trivet 4 include enamel and stainless steel.

[0036] As shown in Fig. 4, the trivet 4 is composed of multiple (here, two) divisible sections 5, 6. Each of the sections 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 section covering the burner 22 located forward of the center in the front-to-rear direction of the cooking section 31 of the top plate 3 is defined as the "front section 5," and the section covering the burner 22 located rearward of the center in the front-to-rear direction of the cooking section 31 of the top plate 3 is defined as the "rear section 6."

[0037] (4.1)Anterior split body The front divided body 5 is a trivet that covers the front burner 22 among the burners 22 arranged in the front-rear direction. As shown in Fig. 1, the front divided body 5 collectively covers both of the pair of left and right burners 22 on the front side. The front divided body 5 constitutes a part of the trivet 4 (here, a full-face trivet).

[0038] 5(A), when the front divisional body 5 is attached to the correct position on the top plate 3, a position C1 in the front divisional body 5 corresponding to the center of the burner 22 is located rearward of a center C2 in the front-rear direction of the front divisional body 5. In other words, the front divisional body 5 is set so that a dimension L1 from the position C1 corresponding to the center of the burner 22 to the front end is longer than a dimension L2 from the position C1 to the rear end.

[0039] In this regard, it is preferable to position the front burner 22 of the multiple burners 22 in the gas stove 1 as far away from the user as possible. If the burner 22 is positioned away from the user, for example, if overflow occurs from the cooking utensil, the overflow can be prevented from reaching the user, and the effect of the heat of the flame of the burner 22 on the user can be suppressed.

[0040] For this reason, the front split body 5 in this embodiment is set so that the dimension L1 from position C1 to the front end is longer than the dimension L2 from position C1 to the rear end, so that the burner 22 is positioned away from the user, while the area from the burner 22 to the front end of the cooking section 31 of the top plate 3 can be used as an area where cooking utensils can be placed.

[0041] FIG. 5(A) shows a plan view of the front division body 5 attached to the top plate 3 in the correct orientation, and FIG. 5(B) shows a plan view of the front division body 5 attached to the top plate 3 in the reversed orientation. As described above, when the front division body 5 is attached to the top plate 3 in the correct orientation, the position C1 corresponding to the center of the burner 22 is shifted rearward with respect to the center C2 of the front division body 5 in the front-rear direction. Therefore, if the user mistakenly attaches the front division body 5 in the reversed orientation (this may be called "misinstallation"), as shown in FIG. 5(B), a part of the front division body 5 enters the installation area of ​​the rear division body 6. Therefore, even if the user tries to attach the rear division body 6 to the top plate 3, the user cannot attach the rear division body 6, and can reliably know that the front division body 5 is incorrectly installed.

[0042] As shown in FIG. 4, the front section 5 includes a frame portion 51, a plurality of legs 52, a mounting portion 53, a plurality of pressing portions 56, a plurality of positioning claws 57, and a plurality of grounding portions 58.

[0043] (4.1.1) Frame Frame portion 51 surrounds burner insertion hole 312 at a position spaced from burner insertion hole 312. Frame portion 51 according to this embodiment surrounds two burner insertion holes 312 that are aligned in the left-right direction, but may surround one burner insertion hole 312, or may surround three or more burner insertion holes 312, for example. Frame portion 51 is formed in a generally rectangular frame shape in a plan view.

[0044] The lower surface of the frame 51 faces the upper surface of the cooking section 31 of the top plate 3. When the front section 5 is attached to the top plate 3, as shown in FIG. 1 , the front side of the frame 51 is aligned along the front outer peripheral edge 33 of the top plate 3, both left and right sides of the frame 51 are aligned along the left and right outer peripheral edge 33 of the top plate 3, and the rear side of the frame 51 is aligned along the center of the cooking section 31 in the front-to-rear direction.

[0045] The cross-sectional shape of the frame 51 is not particularly limited, and examples thereof include a vertically long rectangle, a circle, a rectangle with rounded corners, a flat plate, a pipe, etc. Here, it is formed in a rectangular shape with rounded corners (4 mm wide, 10 mm long).

[0046] When the trivet 4 (front divided body 5) is attached to the top plate 3, a gap is provided between the burner insertion hole 312 and the frame portion 51, as shown in Fig. 5(A). That is, as described above, the frame portion 51 is placed on the top plate 3 at a position spaced from the burner insertion hole 312. The gap between the burner insertion hole 312 and the frame portion 51 does not have to be constant around the circumference of the burner insertion hole 312, or it may be constant. Furthermore, there is no particular limit to the size of the gap.

[0047] (4.1.2) Legs As shown in Fig. 4, the legs 52 stand up from the frame 51 and support the mounting portion 53. The legs 52 allow the mounting portion 53 to be positioned at a predetermined height relative to the top plate 3, and as a result, the height of the cooking utensil placed on the mounting portion 53 relative to the burner 22 can be set to a height relationship that allows effective heating of the cooking utensil. Each leg 52 is formed in a plate shape and attached to the frame 51 so as to be perpendicular thereto. In this embodiment, the legs 52 and the frame 51 are attached by welding, but may be attached by other methods such as fitting, cutting, screwing, riveting, etc.

[0048] (4.1.3) Placement The placement portion 53 is a portion on which cooking utensils are placed. The placement portion 53 is provided at the upper end portion of the leg portion 52. The upper end surfaces of the multiple placement portions 53 are located on the same plane. As shown in Fig. 4, the placement portion 53 includes multiple trivet claws 54 on which cooking utensils are placed when heating, and an auxiliary support body 55 on which cooking utensils are placed when not heating.

[0049] The trivet claws 54 extend radially from a position corresponding to the center of the burner 22. In other words, the trivet claws 54 extend from the upper end of the leg 52 toward the center of the burner insertion hole 312. As shown in FIG. 3(A), the lower surface of the trivet claws 54 is inclined with respect to the horizontal plane so that the tip is located higher. In other words, the trivet claws 54 are formed in a tapered shape with a narrower vertical width toward the tip. The trivet claws 54 may extend along a straight line connecting the upper end of the leg 52 and the center of the burner 22, or only the tip portion may extend radially and the other portions including the base end may be bent relative to the tip portion to extend non-radially.

[0050] 4, the auxiliary support body 55 is configured by combining a plurality of vertical members 551 extending in the front-rear direction and a plurality of horizontal members 552 extending in the left-right direction. The auxiliary support body 55 is provided on both the front section body 5 and the rear section body 6, but is formed in a lattice shape on the front section body 5 and is formed in an H shape on the rear section body 6. The auxiliary support body 55 is not limited to being formed in a lattice shape or an H shape, and may be formed in, for example, a cross shape, a lattice shape, a square shape, a V shape, a T shape, etc.

[0051] (4.1.4) Clamp The pressing portion 56 partially faces the region inside the frame portion 51 of the upper surface of the top plate 3, thereby preventing upward warping of the top plate 3. The pressing portion 56 protrudes downward from the mounting portion 53, and its lower end face faces the upper surface of the top plate 3. In this embodiment, the pressing portion 56 protrudes from the trivet claws 54 of the mounting portion 53, but may also protrude from the auxiliary receiver 55.

[0052] Here, "upward warping" refers to a phenomenon in which the top plate 3 expands due to the effect of heat from the burner 22, causing the cooking surface of the top plate 3 to warp upward relative to the horizontal plane. Upward warping may be accompanied by abnormal noise.

[0053] The holding portions 56 face the inner region of the frame portion 51 on the upper surface of the top plate 3. Since the upward warping phenomenon is more severe the closer to the center of the cooking portion 31 of the top plate 3, the four holding portions 56 located between adjacent burners 22 can more effectively suppress the upward warping. However, even if the holding portions 56 are provided only on the outside of the burners 22 adjacent in the left-right direction, they can still be effective in suppressing the upward warping to a certain extent.

[0054] The pressing portion 56 only needs to face the upper surface of the top plate 3, and may be separated from it by a small gap (i.e., may be in close proximity), or may be in contact with the top plate 3. The pressing portion 56 according to this embodiment is in close proximity to the upper surface of the top plate 3, as shown in FIG. 6(A).

[0055] FIG. 6(A) shows the relationship between the lower end surface of the pressing portion 56 and the upper surface of the top plate 3 when the cooking utensil is not placed on the placement portion 53. A gap S1 is formed between the lower end surface of the pressing portion 56 and the upper surface of the top plate 3. This gap S1 is preferably, for example, 0.1 mm or more and 1.0 mm or less, and more preferably 0.1 mm or more and 0.5 mm or less. If the gap S1 is 0.5 mm or less, when the cooking utensil is not placed on the placement portion 53, a gap S1 is formed between the lower end surface of the pressing portion 56 and the upper surface of the top plate 3, but when a cooking utensil such as a pot or frying pan is placed on it, the lower end surface of the pressing portion 56 comes into contact with the upper surface of the top plate 3 as shown in FIG. 6(C). If the gap S1 exceeds 0.5 mm, the lower end surface of the pressing portion 56 is unlikely to come into contact with the upper surface of the top plate 3 unless the cooking utensil is filled with water or contains food.

[0056] In this way, when no cooking utensil is placed on the placement portion 53, a gap S1 is formed between the lower end surface of the holding portion 56 and the upper surface of the top plate 3. This means that when the trivet 4 is attached to the top plate 3, it is slid over the top plate 3 and positioned in the correct position without the holding portion 56 rubbing against the top plate 3, preventing the top plate 3 from being scratched.

[0057] Furthermore, when a cooking utensil is placed on the placement portion 53 and heated, the pressing portion 56 is in contact with the upper surface of the top plate 3, so that upward warping is unlikely to occur and the generation of abnormal noises associated with upward warping can be suppressed. There are no particular limitations on the force (contact pressure) with which the pressing portion 56 contacts the upper surface of the top plate 3, and the pressing portion 56 may be pressed against the upper surface of the top plate 3 with a constant force, but it is preferable that the pressing portion 56 contacts with as small a contact pressure as possible. If the force with which the pressing portion 56 contacts the upper surface of the top plate 3 is small, the upper surface of the top plate 3 can be prevented from being scratched.

[0058] The pressing portion 56 protrudes downward from the end of the center of the trivet claw 54. The pressing portion 56 is formed with the same width in the protruding direction. As shown in Fig. 6(A), the pressing portion 56 is inclined with respect to the vertical plane so as to move away from the burner insertion hole 312 as it goes downward.

[0059] Therefore, the surface 561 of the pressing portion 56 on the burner insertion hole 312 side is also inclined with respect to the vertical plane so as to move away from the burner insertion hole 312 as it goes downward, so that the trivet claw 54 can be brought as close as possible to the center of the burner 22, and the range of cooking utensils that can be placed on the placement portion 53 can be increased, making it easier to stably place the cooking utensils on the placement portion 53. Furthermore, while bringing the trivet claw 54 as close as possible to the center of the burner 22, the lower end surface of the pressing portion 56 can be made to face the upper surface of the top plate 3, and interference of the flame of the burner 22 with the pressing portion 56 can be suppressed. In addition, since the multiple pressing portions 56 are arranged to surround one burner 22, the portion of the cooking portion 31 of the top plate 3 that is close to the heat source can be pressed, and the upward warping of the top plate 3 can be effectively suppressed.

[0060] (4.1.5) Positioning claws As shown in Fig. 4, the positioning claws 57 protrude from the frame 51 toward the outer periphery 313, and a positioning portion 571 is formed at the tip. The positioning claws 57 extend perpendicular to the frame 51. There are two positioning claws 57 for each burner 22. The two positioning claws 57 are disposed on the front and rear sides of the burner 22 on a straight line parallel to the front-rear direction passing through the center of the burner 22. In this embodiment, the positioning claws 57 are attached to the frame 51 by welding, but may be attached by other methods such as fitting, cutting, screwing, riveting, etc.

[0061] 3(A), the positioning portion 571 is inserted into the recess 314, thereby being positioned relative to the outer periphery 313 of the top plate 3. Therefore, the trivet 4 is not positioned by the outer periphery edge portion 33 of the top plate 3, but is positioned relative to the outer periphery 313 in both the front-rear and left-right directions.

[0062] In this embodiment, the front division body 5 is positioned by two positioning portions 571 with respect to each of the two burners 22 on the left and right (therefore, it is positioned by a total of four positioning portions 571). Also, the rear division body 6 is positioned by two positioning portions 571 with respect to one burner 22 (therefore, it is positioned by a total of two positioning portions 571). However, if one of the front division body 5 and the rear division body 6 is positioned with respect to the outer periphery 313, the other may be positioned with respect to the one division body. For example, if the front division body 5 is positioned with respect to the outer periphery 313, it is sufficient to position the rear division body 6 with respect to the front division body 5. In this case, the rear division body 6 does not need to have the positioning claws 64.

[0063] As shown in Fig. 3(B), the lower end of each positioning portion 571 is tapered so that the thickness decreases toward the lower end. In this embodiment, only the lower end of the positioning portion 571 is tapered, but, for example, the positioning portion 571 may be tapered from the center toward the lower end in the vertical direction, or from the upper end toward the lower end. The positioning portion 571 can be smoothly inserted into the recess 314 by being tapered.

[0064] (4.1.6) Grounding part In the trivet 4, the grounding portion 58 rests on the cooking portion 31 (receiving portion 311) of the top plate 3 and is grounded. In other words, the trivet 4 is supported on the top plate 3 by the grounding portion 58. The grounding portion 58 is made of a cushioning material. The cushioning material can suppress the generation of contact noise between the components 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 51, and examples of the cushioning material include elastomer, soft synthetic resin, hard synthetic resin, resin foam, wood, and cloth.

[0065] 4, grounding portion 58 is attached to the lower end of leg portion 52, whereby a plurality of grounding portions 58 are arranged along frame portion 51. At the lower end of leg portion 52, attachment groove 514 is formed, as shown in FIG. 7. Grounding portion 58 includes foot portion 581 whose lower surface faces receiving portion 311, and locking portion 582 protruding upward from foot portion 581. Locking portion 582 is fitted into attachment groove 514, whereby grounding portion 58 is attached to the lower end of leg portion 52.

[0066] When the trivet 4 has the grounding portion 58 placed on the receiving portion 311 with no cooking utensils placed on the placement portion 53, a gap is formed between the bottom end surface excluding the grounding portion 58 and the upper surface of the top plate 3. As a result, when the trivet 4 is attached to the top plate 3, the trivet 4 and the top plate 3 do not come into contact with each other, suppressing the generation of noise (contact noise) caused by contact between components.

[0067] (4.2) Posterior split body The rear divided body 6 is a trivet that covers the rear burner 22 among the burners 22 lined up in the front-rear direction. The rear divided body 6 differs from the front divided body 5 in that the portion corresponding to the burner 22 is formed in the center in the left-right direction, but has the same basic structure, including a frame portion 61, multiple legs 62, a mounting portion 63, multiple positioning claws 64, and multiple grounding portions 65. Therefore, overlapping descriptions will be omitted below.

[0068] The rear divisional body 6 does not have the pressing portions 56 that the front divisional body 5 has. However, since a plurality of pressing portions 56 are arranged in the front divisional body 5, even if the rear divisional body 6 does not have the pressing portions 56, it is possible to prevent the top plate 3 from warping upward. Note that the rear divisional body 6 may also have pressing portions 56, similar to the front divisional body 5.

[0069] The rear divisional body 6 is attached onto the top plate 3 so that the front edge of the rear divisional body 6 is aligned with the rear edge of the frame portion 51 of the front divisional body 5. Here, the positioning portion of the positioning claw 64 of the rear divisional body 6 is inserted into the recess 314 of the outer circumferential portion 313 to position the rear divisional body 6 with respect to the top plate 3, but positioning may also be achieved by abutting the front edge of the frame portion 61 of the rear divisional body 6 against the rear edge of the frame portion 51 of the front divisional body 5. In this case, the positioning claw 64 may not be necessary.

[0070] (5)Other As described above, the trivet 4 according to this embodiment is positioned relative to the top plate 3, not relative to the outer periphery 33, but relative to the outer periphery 313. For this reason, it is also possible to attach an individual trivet 7 that is attached one-to-one to the burner 22, as shown in Fig. 8. Therefore, by using a common top plate 3, it is possible to provide a gas stove 1 having a trivet 4 according to the user's preference, and inventory management of each part is easy, allowing for high manufacturability.

[0071] The individual trivet 7 has a general structure, for example as follows. The 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 portions 73 provided on the front and rear trivet claws 72. The pair of positioning portions 73 are inserted into recesses 314 in the outer periphery 313, whereby the individual trivet 7 is positioned relative to the outer periphery 313.

[0072] <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.

[0073] (1) Variation 1 The ground contact portions 58, 65 in the above-described embodiments are attached to the lower ends of the legs 52, 62, but in the present invention, the ground contact portions may be attached to the frame portions 51, 61 as shown in Fig. 9. Here, the frame portion 51 of the front separate body 5 will be described as an example, but the same applies to the rear separate body 6.

[0074] The grounding portion 58 is attached to the frame portion 51. The grounding portions 58 are attached at intervals along the frame portion 51. The attachment of the grounding portions 58 to the frame portion 51 is realized by, for example, adhesive bonding, fitting, melting, welding, two-color molding, screwing, pinning, riveting, a snap-fit ​​structure, wrapping, or the like.

[0075] When a cooking utensil is placed on the mounting portion 53, the load from the cooking utensil is transmitted to the frame portion 51 via the trivet claws 54 and the legs 52. Since the legs 52 are attached to the area between the grounding portions 58 of the frame portion 51, the area between the grounding portions 58 of the frame portion 51 may bend due to the force applied from the legs 52. When the area between the grounding portions 58 of the frame portion 51 is bent, the mounting portion 53 moves closer to the burner 22. This affects the heating provided to the cooking utensil.

[0076] In reality, the retaining portion 56 has a certain degree of effect in suppressing deflection, but in this modified example, in addition to the retaining portion 56, the following measures are taken to suppress deflection.

[0077] 10 is an explanatory diagram comparing the height relationship between a cross section in a vertical plane of the grounding portion 58 and a cross section in a vertical plane along the positioning claw 57. One or more positioning claws 57 are disposed between adjacent grounding portions 58.

[0078] 10, a restricting portion 59 is formed at the lower end of the positioning claw 57, protruding downward from the lower end of the frame portion 51. The lower surface of the restricting portion 59 (referred to as a "restricting surface 591") is set to be located between the lower surface of the grounding portion 58 and the lower surface of the frame portion 51. In other words, the dimension L12 between the restricting surface 591 and the grounding portion 58 is smaller than the dimension L11 between the lower surface of the frame portion 51 and the lower surface of the grounding portion 58.

[0079] When force is applied from legs 52, the area between ground contact portions 58 in frame 51 bends by dimension L12, and regulating surface 591 comes into contact with top plate 3. However, the amount of bending of the area between ground contact portions 58 in frame 51 does not exceed dimension L12. Dimension L12 is set so as not to affect the heating applied to the cookware, and L12 is preferably 0.1 mm or more and 1.0 mm or less, and more preferably 0.1 mm or more and 0.5 mm or less.

[0080] In this way, by attaching the grounding portion 58 to the frame portion 51, it is possible to minimize the warping of the areas between the grounding portions 58 in the frame portion 51 while suppressing the generation of contact noise between the components, thereby preventing adverse effects on combustion performance.

[0081] Although the restricting portion 59 is provided at the lower end of the positioning claw 57, it may be provided at the lower end of the leg 52 in a location where there is no positioning claw 57. In the first modification, the restricting portion 59 may be provided at the lower end of the leg 52 connected to the auxiliary receiving body 55, in addition to the leg 52 connected to the trivet claw 54.

[0082] The restricting portion 59 is not limited to the positioning claw 57 and the leg portion 52, and may be provided on, for example, the frame portion 51. The restricting surface 591 is formed in an elongated flat shape made of an end face of a plate so as to fit along the upper surface of the top plate 3, but the shape is not particularly limited, and may be, for example, an arc shape, a spherical shape, a line shape, a point shape, or the like.

[0083] Furthermore, by providing the regulating surfaces 591 at multiple locations, for example, if a user loses the grounding parts 58, 65 while removing the trivet 4 from the top plate 3 for cleaning, even if the trivet 4 is attached to the top plate 3 without attaching the grounding parts 58, 65, the trivet 4 will be supported by the multiple regulating surfaces 591. Therefore, compared to a case in which the regulating surfaces 591 are not provided, the distance between the cooking utensil and the burner 22 can be brought closer to the condition when the grounding parts 58, 65 are provided, and the combustion performance is less likely to be affected.

[0084] (2) Other modifications Modifications of the embodiment are listed below. The modifications described below can be applied in appropriate combination.

[0085] The frame portions 51, 61 in the above-described embodiments are formed in a generally rectangular frame shape when viewed from above, but the present invention is not limited to this and may be formed in, for example, a generally circular frame shape when viewed from above, a generally elliptical frame shape when viewed from above, or a generally trapezoidal frame shape when viewed from above.

[0086] The holding portion 56 according to the above embodiment is provided on four of the six trivet claws 54 for one burner 22, but in the present invention, it may be provided on only one trivet claw 54. The holding portion 56 may also protrude downward from, for example, a part of the vertical member 551 of the auxiliary support body 55. The holding portion 56 may also be configured with, for example, a regulating portion 59 (see Modification 1) protruding downward from the lower end of the positioning claw 57, and even in this case, a certain degree of upward warping suppression effect can be expected.

[0087] The pressing portion 56 according to the above embodiment is formed to have the same width along the protruding direction, but may be formed to have a triangular shape in a side view with the width decreasing downward. Also, in this embodiment, the trivet claw 54 and the pressing portion 56 are formed to have an inverted V shape, but in the present invention, they may be formed, for example, in a T shape or a Z shape.

[0088] In the trivet 4 of the above embodiment, the positioning portion 571 is provided separately from the holding portion 56, but the lower end of the holding portion 56 may be configured to be inserted into the recess 314 of the outer circumferential portion 313, so that the holding portion 56 also serves as the positioning portion 571.

[0089] The gas stove 1 according to the above embodiment is provided with a plurality of burners 22 separated into a front side and a rear side with respect to the center in the front-rear direction of the top plate 3, but in the present invention, the plurality of burners 22 do not have to be separated into a front side and a rear side with respect to the center in the front-rear direction of the top plate 3. For example, two or more burners 22 may be arranged in the left-right direction along the center in the front-rear direction of the top plate 3.

[0090] 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 peripheral edge section 33 are integrally formed, but in the present invention, the cooking section 31 may be made of a stainless steel plate and the outer peripheral edge section 33 and exhaust section 32 may be made of aluminum, or multiple parts may be combined.

[0091] In the gas stove 1 of the above embodiment, the positioning portion 571 is formed by the tip of the positioning claw 57, and is inserted into the recess 314 of the outer periphery 313 to position the trivet 4 relative to the outer periphery 313. However, in the present invention, the positioning portion 571 may be formed by a ring-shaped frame material that surrounds the periphery of the outer periphery 313.

[0092] The front separate body 5 according to the above embodiment is positioned with respect to the outer circumferential portion 313 by a pair of positioning portions 571 spaced apart in the front-rear direction, but may be positioned by a single positioning portion 571 on the front or rear side. Moreover, as the multiple positioning portions 571, three or more positioning portions 571 may be provided.

[0093] The trivet 4 according to 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 4 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 in the front-to-rear direction of the top plate 3 and does not cover the areas on both sides in the left-to-right direction of the rear burner 22. The trivet 4 may also be configured as a combination of the front divided body 5 and individual trivets 7.

[0094] The trivet 4 according to the above embodiment is configured with a divided body divided in the front-rear direction, but may be configured with a divided body divided in the left-right direction, for example. In this case, each divided body is formed in a generally rectangular shape in plan view, for example, with the longitudinal direction being in the front-rear direction.

[0095] The top plate 3 in the above embodiment had an outer peripheral edge portion 33 rising from the cooking portion 31, but the outer peripheral edge portion 33 does not have to rise from the cooking portion 31, and 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.

[0096] In the trivet 4 according to the above embodiment, the grounding portions 58, 65 are provided partially in the circumferential direction of the frame portions 51, 61. However, for example, the grounding portions may be provided over the entire circumferential length of the frame portions 51, 61.

[0097] The front split body 5 according to the above embodiment is configured to cover two burners 22, but the front split body 5 may be configured to be separable in the left-right direction.

[0098] The trivet 4 according to the above embodiment is configured to cover the entire surface of the cooking section 31 of the top plate 3, but it may be configured to cover the exhaust section 32 and the entire surface of the cooking section 31.

[0099] In the front divided body 5 according to the above embodiment, the position C1 corresponding to the center of the burner 22 is located behind the center of the front divided body 5 in the front-rear direction, but the position C1 corresponding to the center of the burner 22 may be located forward of the center of the front divided body 5 in the front-rear direction. In this case, when a cooking utensil is placed directly above the front burner 22, it is advantageous that other cooking utensils can be easily placed behind the cooking utensil. In this case, even if the front divided body 5 is installed incorrectly, a gap is generated between the rear end of the front divided body 5 and the rear divided body 6, so that the user can easily know that the trivet 4 is installed incorrectly.

[0100] In the above embodiment, the pressing portion 56 is provided only on the trivet claw 54 of the front split body 5, but in the present invention, the pressing portion 56 is provided only on the trivet claw 54 of the rear split body 6 and does not necessarily have to be provided on the front split body 5.

[0101] In the trivet 4 of the above embodiment, the mounting portion 53 is fixed to the frame portion 51 via the legs 52, but in the present invention, if the frame portion 51 is tall, the mounting portion 53 may be fixed directly to the frame portion 51.

[0102] In this specification, expressions accompanied by "approximately", such as "approximately parallel" or "approximately perpendicular", may be used. For example, "approximately parallel" means that the state is substantially "parallel", and includes not only a strictly "parallel" state but also an error of a few degrees. The same applies to other expressions accompanied by "approximately".

[0103] Furthermore, in this specification, expressions that are distinguished 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 a region having 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".

[0104] <Summary> As described above, the gas stove 1 according to the first embodiment comprises a top plate 3 having a burner insertion hole 312 through which a burner 22 passes, and a trivet 4 attached to the top plate 3 and on which cooking utensils are placed. The trivet 4 has a frame 51 surrounding the burner insertion hole 312 at a position spaced from the burner insertion hole 312, a mounting portion 53 fixed to the frame 51 and on which cooking utensils are placed, and a pressing portion 56 partially facing the area on the upper surface of the top plate 3 inside the frame 51.

[0105] According to this embodiment, the pressing portion 56 faces the inner region of the frame portion 51 of the top plate 3, making it less likely for the inner region of the frame portion 51 to warp upward, and suppressing the generation of abnormal noise from the top plate 3 associated with upward warping.

[0106] In the gas stove 1 according to the second embodiment, in the first embodiment, the pressing portion 56 protrudes downward from the mounting portion 53, and the lower end face thereof faces the upper surface of the top plate 3.

[0107] According to this embodiment, the load of the cooking utensil placed on the placement portion 53 can be utilized to suppress the occurrence of upward warping.

[0108] In the gas stove 1 of the third aspect, in the second aspect, when no cooking utensil is placed on the mounting portion 53, a gap S1 is formed between the lower end surface of the pressing portion 56 and the upper surface of the top plate 3.

[0109] According to this embodiment, when the trivet 4 is attached to the top plate 3, the pressing portion 56 does not rub against the top plate 3, and therefore, the top plate 3 can be prevented from being scratched.

[0110] In the gas stove 1 according to the fourth aspect, in any one of the first to third aspects, the mounting portion 53 includes a plurality of trivet claws 54 extending toward the center of the burner insertion hole 312. The pressing portion 56 protrudes downward from the end portion on the center side of at least one of the plurality of trivet claws 54.

[0111] According to this embodiment, the periphery of the burner 22 can be pressed by the pressing portion 56, and the occurrence of upward warping can be effectively suppressed.

[0112] In the gas stove 1 according to the fifth embodiment, in the fourth embodiment, the surface 561 of the pressing portion 56 on the burner insertion hole 312 side is inclined with respect to the vertical plane so as to move away from the burner insertion hole 312 in the downward direction.

[0113] According to this embodiment, the trivet claws 54 can be brought as close as possible to the burner 22 while preventing the retaining portion 56 from coming too close to the flame port 226.

[0114] The gas stove 1 according to the sixth aspect is in any one of the first to fifth aspects and includes a plurality of burners 22 and a plurality of burner insertion holes 312. The trivet 4 is configured to collectively cover at least two of the plurality of burners 22.

[0115] According to this embodiment, by using a trivet 4 that covers two or more burners 22 collectively, cooking utensils can be placed not only on the burners 22 but also between the burners 22, improving usability while suppressing the occurrence of upward warping.

[0116] In the gas stove 1 according to the seventh aspect, in any one of the first to sixth aspects, the top plate 3 has a plurality of outer periphery parts 313 formed around the burner insertion hole 312 to prevent liquid from entering the burner insertion hole 312. The trivet 4 has a positioning part 571 that is positioned relative to the outer periphery parts 313.

[0117] According to this embodiment, the trivet 4 can be positioned relative to the outer periphery 313, which improves the freedom of design of the outer periphery 313 of the top plate 3. In addition, since 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 deterioration of combustion performance due to misalignment of the mounting position of the trivet 4 relative to the top plate 3 can be prevented.

[0118] In the gas stove 1 according to the eighth aspect, in the seventh aspect, a recess 314 is formed in the outer circumferential portion 313. The trivet 4 has a positioning claw 57 which is fixed to the frame portion 51 and has a tip portion which is inserted into the recess 314. The positioning portion 571 is formed by the tip portion of the positioning claw 57.

[0119] According to this embodiment, the contact area between the positioning portion 571 and the outer circumferential portion 313 can be made as small as possible, and the generation of contact noise between the members can be suppressed as much as possible.

[0120] In gas stove 1 according to the ninth aspect, in the eighth aspect, the lower end of positioning portion 571 is formed in a tapered shape such that the thickness dimension decreases toward the lower end.

[0121] According to this embodiment, the positioning portion 571 can be smoothly inserted into the recess 314 .

[0122] In the gas stove 1 according to the tenth aspect, in any one of the first to ninth aspects, the trivet 4 is composed of a plurality of divisible segments. Each of the plurality of segments has a frame portion 51, 61 and a mounting portion 53, 63, and at least one of the plurality of segments has a pressing portion 56.

[0123] According to this embodiment, the trivet 4 is made up of a plurality of divided bodies, which makes it easy to handle when cleaning.

[0124] In the gas stove 1 according to the eleventh aspect, in the tenth aspect, the trivet 4 has, as a plurality of divided bodies, a front divided body 5 covering the burner 22 located forward of the center in the front-to-rear direction of the top plate 3, and a rear divided body 6 covering the burner 22 located rearward of the center in the front-to-rear direction of the top plate 3. The front divided body 5 is configured so that a portion of the front divided body 5 corresponding to the center of the burner 22 is located rearward of the center in the front-to-rear direction of the front divided body 5.

[0125] According to this embodiment, if the trivet 4 is erroneously installed on the top plate 3, the rear end of the front divided body 5 will enter the installation area of ​​the rear divided body 6. In this case, since the rear divided body 6 cannot be attached, the user can be sure that the front divided body 5 has been erroneously installed.

[0126] In the gas stove 1 according to the twelfth aspect, in any one of the first to eleventh aspects, the trivet 4 has a grounding portion 58, 65 that is provided on the frame portion 51, 61 and rests on the upper surface of the top plate 3. The grounding portion 58, 65 is made of a cushioning material.

[0128] In the gas stove 1 according to the thirteenth aspect, in the twelfth aspect, the grounding portions 58,65 are provided at intervals along the frame portions 51,61. The placement portions 53,63 are connected to the frame portions 51,61 within the area between the adjacent grounding portions 58,65. The trivet 4 has a restricting portion 59 provided between the adjacent grounding portions 58,65, which restricts the deflection of the frame portions 51,61. The lower surface of the restricting portion 59 is located between the lower surfaces of the grounding portions 58,65 and the lower surfaces of the frame portions 51,61 in the vertical direction.

[0129] According to this embodiment, when a cooking utensil is placed on the mounting portion 53, 63, bending of the area between the contact portions 58, 65 of the frame portion 51, 61 can be minimized, thereby preventing any adverse effects on the performance of heating the cooking utensil.

[0130] The trivet 4 according to the fourteenth embodiment is attached to a top plate 3 having a burner insertion hole 312 through which a burner 22 passes, and is used to place cooking utensils on.
