  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  A gas stove that is a cooking device includes a main body (not shown) that serves as a base to which a burner 2 for a stove, an operation unit (not shown), a control device (not shown), and the like are attached, and an upper end of the main body. The top plate 1 (that is, the top plate) which is attached to the top plate and forms the top surface portion, and the stove portion 11 formed on the top plate 1 are provided. The top plate 1 is mainly composed of a metal plate such as an aluminum alloy or a glass plate, and a chemical conversion film is formed on the surface thereof. In the present embodiment, as shown in FIG. 1, a left stove portion 11a having a standard burner 2a is provided on the upper surface of the top plate 1 in front of the left side, and a rear stove having a small burner 2b is provided. The part 11b is provided in the back of the center part in the left-right direction, and the right cooking unit 11c provided with the high heating power burner 2c is provided in front of the right side.

  As shown in FIG. 2A, the burner 2 is formed on the mixing pipe 21 attached to the main body, the burner body 22 formed on the upper end of the downstream side of the mixing pipe 21, and the upper part of the burner body 22. The burner head 23 is exposed above the top plate 1 through a burner opening 10 (see FIG. 2B) drilled in the top plate 1. In the present embodiment, as shown in FIG. 1, three substantially circular burner openings 10 (see FIG. 2B) serving as the stove portions 11 a to 11 c are respectively provided on the left side of the top plate 1 and on the left and right sides. The standard burner 2a, the small burner 2b, and the high-heat-power burner 2c are inserted through the burner opening 10 from below and project upward. And, on the upper surface of the top plate 1, the virtues 4 in which the burners 2 are arranged in the center are provided. The burner 2 and the virtues 4 are heated objects such as a pot placed on the virtues 4 (not shown). 1) is formed.

  As shown in FIGS. 3 and 4, the virtues 4 are formed by integrally assembling a substantially annular virtuosity frame 41 and a plurality of virtues claws 42. In the present embodiment, the virtuosity frame 41 is formed by bending a metal round bar having a substantially circular cross section in an annular shape in plan view, and a plurality of virtues claw 42 in the circumferential direction of the virtuosity frame 41 (this embodiment) 6 in the form) are formed at substantially equal intervals. The virtue frame 41 may not have an annular shape in plan view, and a part of the circumferential direction may be interrupted, and the shape in plan view is not particularly limited, such as a substantially circular shape or a substantially square shape.

  As shown in FIGS. 3 and 4, the virtuosity claw 42 is a flat plate mainly composed of a metal having a predetermined thickness formed in a substantially U shape. In this embodiment, the steel plate is coated with a heel coating. It is made of a polished steel plate or a stainless steel plate. The pointed tip 42a of the lower piece of the five virtue claws 42, which is substantially U-shaped, is fixed to the five virtue frame 41 by welding and is integrally formed. Then, a part of the five virtue claws 42 is fitted in such a manner as to project inward beyond the virtue frame 41 and project downward from the upper side of the portion welded to the inner virtue frame 41 on the inner side (center side of the virtue frame 41). A protruding piece 43 is formed. The fitting protrusions 43 are formed on two five virtue claws 42 provided respectively at substantially the center of the two arcuate portions 41a of the five virtue frame 41.

  As shown in FIG. 2, a burner ring 3 having a substantially annular shape in plan view is interposed in a gap S between the inner end edge of the burner opening 10 of the top plate 1 and the outer peripheral surface of the burner body 22 of the burner 2. . The burner ring 3 is composed of a cylindrical portion 31 having a substantially cylindrical shape, and an outer flange portion 32 that protrudes over the entire circumference on the outer peripheral side of the upper end portion of the cylindrical portion 31, and in the present embodiment, An inner flange portion 33 is provided on the inner circumferential side of the upper end portion of the cylindrical portion 31 so as to protrude over the entire circumference (see FIGS. 2 and 8).

  Further, as shown in FIGS. 2 and 8, the fitting protrusion 43 is positioned on the upper surface of the outer flange portion 32 of the burner ring 3 in a state in which the five virtue frame 41 and the burner ring 3 are fitted by positioning means described later. A fitting recess 35 into which the fitting protrusion 43 is fitted is provided in the portion to be fitted. The fitting recess 35 is formed to have a width that is substantially the same as or slightly wider than the thickness of the fitting protrusion 43 and is substantially the same as or slightly longer than the length of the fitting protrusion 43. Then, the fitting protrusion 43 is fitted into the fitting recess 35. Thereby, in addition to the fitting by the positioning means, the positioning of the virtues 4 with respect to the burner ring 3 can be further strengthened by the fitting of the fitting protrusion 43 and the fitting recess 35.

  Then, the burner ring 3 is attached to the top plate 1. In this embodiment, the cylindrical portion 31 of the burner ring 3 is inserted through the burner opening 10 from above the top plate 1 and attached. Thereby, the burner ring 3 is attached to the top plate 1 at a predetermined position and a predetermined direction. A concave groove 34a having a ring shape in plan view is formed on the lower surface of the outer flange portion 32 of the burner ring 3, and a sealing member 34b is loaded in the concave groove 34a. When the burner ring 3 is attached to the top plate 1, the outer flange portion 32 comes into contact with the upper surface of the peripheral edge of the burner opening 10 of the top plate 1. At this time, the seal member 34 b is pressed against the upper surface of the top plate 1. The seal is made.

  The five virtues 4 need to be attached to the burner ring 3 in a predetermined position and a predetermined direction, and positioning means for that purpose is provided. In the present embodiment, as the positioning means, the shape of the five-virtual frame 41 in a plan view is made non-circular, and a five-virtual frame fitting portion capable of fitting the five-virtual frame 41 to the outer flange portion 32 of the burner ring 3 is provided. .

  In this embodiment, as shown in FIGS. 3 and 4, the virtually frame 41 is formed in a plan view shape with a part of the annular circumferential direction being an arc and the remaining part is formed by extending the arc. In particular, in the illustrated example, the two arcuate portions 41a on the same circle having a central angle of about 150 degrees are opposed to each other, and the distance is slightly separated. The end portions on the same side of the arc-shaped portion 41a are connected by a straight line portion 41b to be a point-symmetric shape. The central angle of the arcuate portion 41a may not be 150 degrees.

  In the present embodiment (see FIGS. 2 and 8), the burner ring 3 forms an arcuate portion and a straight portion corresponding to the arcuate portion 41a and the straight portion 41b of the virtually frame 41, and The outer shape of the portion 32 is formed in substantially the same shape as the plan view shape of the virtuosity frame 41, and this outer peripheral edge functions as a virtuosity frame fitting portion.

  As shown in FIG. 8, the inner peripheral edge of the five virtue frame 41 is fitted into the outer peripheral edge of the outer flange portion 32 of the burner ring 3. Since the outer shape of the outer frame portion 32 of the virtuosity frame 41 and the burner ring 3 is non-circular, the virtues 4 are positioned with respect to the burner ring 3 when the virtues 4 and the burner ring 3 are fitted. It cannot be rotated relative to the circumferential direction. Thereby, the attachment position and direction with respect to the burner ring 3 of the 5 virtue frame 41 can be made into a predetermined position and a predetermined direction.

  Thus, when the virtues 4 are attached to the burner ring 3 attached to the top plate 1 in a predetermined position and in a predetermined direction, the outer peripheral portion 42b of the lower piece of the virtues 4 is seated on the top plate 1. However, when the outer peripheral part 42b is directly seated on the top plate 1, when a heavy pan or the like is placed on the virtues 4, the outer peripheral part 42b scratches or bites the chemical film on the surface of the top plate 1 to form a chemical film. There is a risk of cocoon formation. Once wrinkles are formed, dirt enters the wrinkles and causes corrosion, and the aesthetics are also impaired. Therefore, the virtues 4 are placed on the top plate 1 via the buffer member 7 so that the outer peripheral portion 42b does not directly contact the top plate 1 as shown in FIGS.

  As shown in FIGS. 3 and 4, a portion of the outer peripheral portion 42 b of Gotoku 4 placed on the top plate 1 is a seating portion 8, and the buffer member 7 is attached to the seating portion 8. In the present embodiment, the seating portion 8 is formed at the end portion of the five virtue claws 42 that is farthest from the center of the substantially annular five virtue frame 41 in plan view, thereby stably supporting the five virtues 4. It is possible to suppress the influence of heat transfer to the gas stove.

  A recess 81 is formed in the seating portion 8 upward from the lower surface. The concave portion 81 is provided so that the projecting pieces 82 approach each other from both sides of the opening edge at the lower end, and between the tips of the projecting pieces 82 becomes the inlet opening 81a, and the upper side of the inlet opening 81a is more than the inlet opening 81a. The widened portion 81b is wide in the horizontal direction.

  As shown in FIG. 5, the shock-absorbing member 7 is press-fit in the recess 81, and is fitted in the shape of the upper spread portion 81 b and the fit-in portion 71 is press-fit in the recess 81. A thickness direction regulating portion 72 for regulating the movement of the five virtue claws 42 of the buffer member 7 in the plate thickness direction, a retaining portion 73 that is recessed at the lower end portion of the fitting portion 71 and into which the projecting piece 82 enters, and a top plate And a top plate abutting portion 74 that abuts with. In the present embodiment, the buffer member 7 is made of rubber, but is not particularly limited to rubber, and the surface of the top plate 1 is not wrinkled (or hardly wrinkled) even if pressed against the surface of the top plate 1. Any material can be used.

  When the fitting portion 71 of the buffer member 7 is press-fitted into the concave portion 81 of the virgin claw 42, as shown in FIG. 7 (c), the protruding piece 82 of the lower piece of the virgin claw 42 enters the retaining portion 73, As shown in FIGS. 6 and 7, the buffer member 7 is attached to the virtuosity claw 42 in a state of being prevented from coming off. At this time, it is easy to get over the protruding piece 82 by the inclined portion 71a (see FIG. 5) formed in the fitting portion 71 and inclined so that the width becomes shorter as it goes upward. When the fitting portion 71 is press-fitted in the recess 81, a gap of approximately 0.2 mm is formed in the horizontal direction between the insertion portion 71 and the inner wall of the upper spreading portion 81 b, and the upper end of the fitting portion 71 is pressed against the upper end of the recess 81. The size is formed.

  Since the upper end of the insertion portion 71 is press-fitted so as to be in pressure contact with the upper end of the concave portion 81, when the pan is placed on the virtuosity claw 42, the insertion portion 71 receives a part of the load, The load applied to the top plate contact portion 74 from the lower end of the portion 8 is reduced, and the shear stress generated in the top plate contact portion 74 due to the downward force by the lower end of the seating portion 8 is reduced, and the top plate contact portion 74 is hard to be damaged.

  In this way, by placing the virtues 4 on the top plate 1 via the buffer members 7, the virtues 4 directly contact the top plate 1 to prevent wrinkles on the surface of the top plate 1 or creases. The risk of sticking is reduced.

  Further, in the present embodiment, as shown in FIG. 2, the lower surface of the virtuosity frame 41 is positioned higher than the lower surface of the seating portion 8, and the virtues 4 are mounted on the top plate 1 via the buffer members 7. When placed, the frame 5 is not in contact with the top plate 1. Thereby, the part which contacts the top plate 1 decreases and the top plate 1 becomes more difficult to be wrinkled. Even if the lower surface of the virtually frame 41 is located below the lower surface of the seating portion 8, the lower surface of the virtually frame 41 is higher than the lower surface of the buffer member 7 when the buffer member 7 is attached. It only has to be located.

  Further, in order to remove the buffer member 7 press-fitted in the concave portion 81 of the virgin pawl 42, when the buffer member 7 is applied in the direction toward the top plate contact portion 74 (that is, downward), the buffer member 7 is buffered. The fitting portion 71 of the member 7 can be elastically deformed to get over the protruding piece 82, move in the direction along the plate thickness direction restricting portion 72 (that is, downward), and come off from the virtuosity claw 42.

  In the present invention, the recess 81 and the buffer member 7 are shaped as described above, so that the buffer member 7 can be easily attached to and detached from the virtues 4. Further, by supporting a part of the load applied when an object to be heated such as a pan is placed on Gotoku 4 with the fitting portion 71, the shearing force at the top plate contact portion 74 that contacts the top plate 1 is reduced. Since the top plate contact portion 74 is less likely to be damaged, the top plate 1 is further less likely to be wrinkled.

  In addition, when attaching the buffer member 7 to the virtuosity claw 42, the buffer member 7 can be bonded to the virtues 4 by applying an adhesive, and the buffer member 7 which is a small member is lost during use. It can be made more sure to prevent.

  Further, by not using an adhesive, the attachment and detachment of the buffer member 7 to and from the virtues 4 can be easily and repeatedly performed. Therefore, it is convenient that the virtues 4 can be washed separately.

  In addition, Gotoku 4 generally has specifications that form a coating film on a metal such as iron, and specifications that are formed of a metal such as stainless steel that does not have a coating film. The width and height dimensions of the recess 81 before the formation of the cocoon film formed on the virgin claw 42 formed with the cocoon film on the metal of the above are formed on the virtuo claw 42 of the specification that does not form the cocoon film. Compared with the dimension of the recessed part 81, it is formed larger by about 0.4 to 0.8 mm. As a result, a cocoon film is formed on the virtuosity claw 42 of the fabric that is formed to a large extent as described above. The same width and height can be achieved. Thereby, the shape of the buffer member 7 used for the virtues 4 with the specification for forming the heel coating and the virtues 4 with the specification for not forming the heel coating can be the same size. That is, the size of the recessed portion 81 to be formed is changed in accordance with the post-treatment of the metal forming the virtues 4 so that the final recessed portion 81 has the same size.

  Moreover, in this embodiment, as shown in FIG. 9, the ring cover 5 which covers the upper surface of the burner ring 3 is provided. As a result, even if the broth spills from the pan during cooking, the dirt does not adhere to the burner ring 3 but adheres to the ring cover 5, so that only the ring cover 5 needs to be washed and the careability is improved. Is.

  Furthermore, the ring cover 5 is disposed between the outer periphery of the burner 2 (specifically, the outer periphery of the burner head 23) and the inner periphery of the virtuosity frame 41. It will be better. A notch 51 for releasing the fitting protrusion 43 is formed in a portion corresponding to the fitting protrusion 43.
