  However, in the above-described conventional gas stove, when spilling occurs during cooking, there is a problem that the spilling stagnation stays in the recess, and burns due to the combustion heat of the stove burner and sticks as dirt that is difficult to remove. Moreover, in this thing, since the said recessed part is provided in the position close | similar to a burner body, cooking containers, such as a pan and a frying pan mounted in Gotoku, became obstructed, and the fitting state of the said recessed part and convex part That is, there is also a problem that it is difficult to visually check whether the five virtues are correctly set on the top surface of the top plate in a rotation-preventing state.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a gas stove that is easy to clean and easy to use in a gas stove in which a stove burner is disposed on a top plate.

  The present invention is provided with the burner body of the stove burner protruding upward from the burner opening of the top plate of the stove body, and the five virtues are provided on the top plate in a state of being positioned in the front, rear, left and right with respect to the burner body. In this gas stove, a rotation preventing portion for preventing rotation of the five virtues in the circumferential direction of the burner body is provided on the top plate outer frame provided along the outer peripheral edge of the top plate.

  In this case, since the five virtue rotation preventing portions are provided at the outer peripheral position of the top plate, it is not necessary to provide an unevenness for preventing the five virtues from rotating around the outer periphery of the burner body. Therefore, dirt such as boiled spills is less likely to stay around the burner body. In addition, by providing the five virtue rotation prevention portion at a position away from the burner body, it is difficult for spillage to adhere to the rotation prevention portion, and it is difficult for the cooking container to obstruct the state of the rotation prevention portion. It is also possible to reliably recognize whether the five virtues are correctly set in the rotation-blocking state.

  Further, according to the present invention, in the gas stove, an engaged portion that engages the lower frame of the virtues is provided on the outer periphery of the burner body, and the virtues are burnered by engaging the lower frame with the engaged portions. Positioned to the front, back, left and right with respect to the body.

  In this case, by engaging the lower frame with the engaged portion on the outer periphery of the burner body, the five virtues are positioned front and rear, left and right with respect to the burner body, and further at the rotation blocking portion provided on the top plate outer frame Since the rotation of the virtues in the circumferential direction is prevented, it is relatively easy to set the virtues at the correct position, and it is also easy to recognize whether the virtues are correctly set in the rotation prevention state. It is.

  Further, in the gas stove according to the present invention, a convex portion is provided at a position outside the lower portion of the virtues, and a concave portion for fitting the convex portion of the virtues as the rotation blocking portion is provided on the top plate outer frame. It is.

  In this case, it is configured so that the rotation of the virtues in the circumferential direction of the burner body is prevented by fitting the convex portion provided at the position outside the lower part of the virtues to the concave portion of the outer frame of the top plate. Therefore, when setting the virtues on the top board, it is easy to visually recognize the direction of the virtues and the positional relationship between the convex portions and the concave portions. Therefore, it is possible to more reliably recognize whether or not the five virtues are correctly set in the rotation prevention state.

  In the gas stove according to the present invention, the rotation prevention portion is provided on the side surface side of the stove body in the outer frame of the top plate.

  In this case, since the cooking container is less likely to obstruct the state of the rotation prevention portion compared to the case where the rotation prevention portion is provided behind the stove body, the five virtues are set correctly in the rotation prevention state. It is possible to more reliably recognize whether or not

  As described above, according to the present invention, dirt such as spilled oil is less likely to stay around the burner body, so that the cleaning property is improved. Further, since it is easy to visually check whether the five virtues are correctly set in the rotation prevention state, the usability is also improved.

Next, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings.
As shown in FIG. 1, a gas stove 1 according to an embodiment of the present invention is a so-called gas table stove that is used by being placed on a kitchen table, and constitutes an upper surface portion of a substantially rectangular box-like stove body 10. The top plate 101 is provided with a single or plural (two in this case) stove burner 2. In addition, on the arrangement portion of the stove burner 2 on the top surface of the top plate 101, the virtues 3 that support cooking containers such as pots and pans are placed. Furthermore, the stove body 10 is provided with a grill cabinet 100 for grilling food ingredients.

  On the front surface portion 102 of the stove body 10, a stove point fire extinguishing operation button 12 for igniting and extinguishing the stove burner 2 and a grill point for igniting and extinguishing a grill burner (not shown) provided in the grill cabinet 100 are provided. A fire extinguishing operation button 13 is provided. In the present embodiment, the front portion 102 is the front of the gas stove 1, the depth direction when the gas stove 1 is viewed from the front portion 102 side is referred to as the front-rear direction, the width direction is referred to as the left-right direction, and the height direction is referred to as the up-down direction.

  The top plate 101 is formed of a glass plate having high heat resistance and impact resistance. Further, the outer peripheral edge of the top plate 101 is surrounded by a metal frame body (hereinafter referred to as “top plate outer frame”) 14 such as aluminum or stainless steel over the entire periphery. The top plate 101 may be formed of a steel plate whose surface is subjected to finish processing such as heat-resistant coating or wrinkles.

  The upper surface of the central portion (hereinafter referred to as “top plate central portion”) 101A of the top plate 101 is provided at a position lower than the upper surface of the outer peripheral portion (hereinafter referred to as “top plate outer peripheral portion”) 101B of the top plate 101. In this way, boiled spills generated during cooking are prevented from flowing out from the top plate 101.

  A substantially circular burner opening 15 for allowing the burner body 20 of the stove burner 2 to face upward is provided at the center portion 101A of the top plate. On the other hand, an exhaust port 16 communicating with the inside of the grill cabinet 100 is provided at a position near the rear of the stove main body 10 in the outer peripheral portion 101B of the top plate.

  As shown in FIGS. 1 to 3, the stove burner 2 is incorporated in the stove main body 10 with a substantially cylindrical burner body 20 protruding upward from the burner opening 15. Further, although not shown, a valve unit that opens and closes in response to the ignition operation or the fire extinguishing operation of the stove point fire extinguishing operation button 12 is incorporated in the stove body 10, and gas is introduced into the burner body 20 through the valve unit. Is supplied.

  A burner head 21 having a plurality of flame holes 210 on the outer periphery is mounted on the upper part of the burner body 20, and the gas supplied into the burner body 20 is ejected from the flame holes 210 to the outer periphery of the burner head 21. . Although not shown, a spark discharge is generated in the vicinity of the flame hole 210 by the ignition operation of the stove point extinguishing operation button 12 in the gap between the inner peripheral edge of the burner opening 15 and the outer peripheral surface of the burner body 20. An ignition plug for igniting the ejected gas and a flame detection sensor for detecting the presence or absence of a gas combustion flame outside the flame hole 210 are provided.

  Around the outer periphery of the burner body 20, a substantially disc-like burner ring 22 that covers the gap between the inner peripheral edge of the burner opening 15 and the outer peripheral surface of the burner body 20 from the upper surface side of the top plate 101 is mounted. The burner ring 22 prevents boiled spills generated during cooking from flowing directly into the stove body 10 through the burner opening 15.

  As shown in FIG. 2, the burner ring 22 includes a sensor insertion hole 221 and a sensor cutout 222. When the burner body 20 is mounted on the burner body 20, the ignition plug and the flame detection sensor are connected to the sensor insertion hole 221 and the sensor insertion hole 221. It is inserted through the sensor notch 222.

  Gotoku 3 has an annular lower frame 30 having an inner diameter substantially the same as the outer diameter of the burner ring 22 and a plurality (six in this case) of substantially U-shapes standing on the outer periphery of the lower frame 30. The lower claw 30 is ring-engaged with the outer periphery of the burner ring 22 to be positioned front-rear and left-right with respect to the burner body 20.

  Further, the virtues 3 are formed symmetrically in the front-rear direction. Like the gas stove 1 according to the present embodiment, the two stove burners 2 are arranged symmetrically on the upper surface portion 101 of the stove body 10. If the five virtues 3 placed on the arrangement part of the one stove burner 2 are rotated 180 degrees, they can be placed on the other part of the stove burner 2 as well. In other words, the common virtues 3 can be used for the left and right stove burners 2.

  The support claws 31 are arranged in a radial pattern from the upper part of the outer peripheral edge of the lower frame 30 to the outside. In addition, in the state where the virtues 3 are set on the top surface of the top plate 101 in the correct position and orientation, the support claws disposed on the lateral extension line passing through the center of the lower frame 30 at a position near the side surface portion 104 of the stove body 10 31A (hereinafter referred to as “outer center claw”) extends to a position where the outer end surface 310 substantially coincides with the outer surface of the top plate outer frame 14.

  As shown in FIGS. 2 and 3, a downwardly protruding protrusion 32 is formed at a corner portion between the outer end surface 310 and the lower end surface 311 of the outer central claw 31 </ b> A. On the other hand, the upper end surface 141 of the top plate outer frame 14 is formed with a notch 42 that is recessed downward to fit the protruding piece 32 as a rotation preventing portion of the virtues 3. By inserting 32, rotation of Gotoku 3 in the burner body 20 circumferential direction is prevented.

  The width dimension of the notch 42 in the front-rear direction is set to be substantially the same as the thickness dimension of the protrusion 32 in the front-rear direction, and the protrusion 32 is closely fitted to the notch 42 while being sandwiched from the front and rear. Therefore, the heat of Gotoku 3 heated to high temperature during cooking is transmitted to the top plate outer frame 14 via the projecting piece 32 and released to the outside of the gas stove 1. Thereby, the thermal load to Gotoku 3 is reduced. Similarly, the heat of the top plate 101 and the burner ring 22 that are heated during cooking is also transmitted to the top plate outer frame 14 through the five virtues 3 and released to the outside of the gas stove 1. Therefore, overheating of the top plate 101 is suppressed, and it is also possible to reduce spillage from being heated and sticking on the surface of the burner ring 22.

  When the virtues 3 are set on the top surface of the top plate 101 in the correct position and orientation, the lower end surface 311 of the outer central claw 31A is in contact with and supported by the top surface of the top plate outer peripheral portion 101B. On the other hand, the lower end surface 313 of the support claw 31 other than the outer central claw 31A is abutted and supported by the upper surface of the top plate central portion 101A.

  The upper end surface 141 of the top plate outer frame 14 is set to a height that substantially matches the top surface of the top plate outer peripheral portion 101B. Further, a part of the outer peripheral end surface 105 of the top plate 101 faces outward from the notch 42, and the projecting piece 32 is fitted into the notch 42 with the inner end surface 325 contacting the outer peripheral end surface 105. .

  Thus, according to the above-described embodiment, since the notch 42 that prevents the rotation of the virtues 3 is provided at the outer peripheral position of the top plate 101, the upper surface of the burner ring 22, the outer peripheral edge, etc. There is no need to provide irregularities for preventing the rotation of the virtues 3 near the outer periphery. Accordingly, dirt such as boiled spills does not easily stay around the burner body 20, and cleaning is easy. In addition, since the notch 42 is provided at a position away from the burner body 20, spillage is less likely to adhere to the notch 42, so that it is easier to clean. In addition, the cooking container placed on Gotoku 3 is unlikely to obstruct the state of fitting between the projecting piece 32 and the notch 42, and Gotoku 3 is set on the top surface of the top plate 101 in a state of preventing rotation. It is easy to use because it can be recognized with certainty.

  Further, in this case, the five frames 3 are positioned in the front-rear and left-right directions with respect to the burner body 20 by engaging the lower frame 30 with the engaged portion on the outer periphery of the burner body 20 (here, the outer periphery of the burner ring 22). Furthermore, since the rotation of the virtues 3 in the circumferential direction of the burner body 20 is prevented by the notches 42 provided in the top plate outer frame 14, the virtues 3 can be set in the correct position relatively easily. It is also easy to recognize whether the virtues 3 are correctly set in the rotation blocking state. Therefore, it is easier to use.

  In this case, the corner 32 between the outer end surface 310 and the lower end surface 311 of the outer central claw 31A, that is, the projecting piece 32 provided at a position outside the lower portion of the five virtues 3 is attached to the top plate outer frame 14. Since it is configured to prevent the rotation of the virtues 3 by being fitted to the notches 42 of the upper end surface 141, when setting the virtues 3 on the top plate 101, It is easy to recognize the positional relationship with the notch 42. Moreover, when Gotoku 3 is mounted on the burner ring 22 in the left and right direction, the projecting piece 32 comes into contact with the upper surface of the top plate central portion 101A, while the lower end surface of the support claw 31 on the opposite side to the outer central claw 31A. Since 313 contacts the upper surface of the outer peripheral portion 101B of the top plate, the backlash is large and the posture of Gotoku 3 is not stable. Therefore, it can be more reliably recognized whether or not the virtues 3 are correctly set on the upper surface of the top plate 101 in a rotation preventing state. Therefore, it is even easier to use.

  Further, in this case, a notch 42 for fitting the projecting piece 32 as a rotation blocking portion of the virtues 3 is provided at a position above the side surface portion 104 of the stove main body 10 on the upper end surface 141 of the top plate outer frame 14. Therefore, compared with the thing provided with the rotation prevention part in the back of the stove main body 10, it is hard to become obstructive that a cooking container visually recognizes the fitting state of the protrusion 32 and the notch 42. FIG. Therefore, it can be more reliably recognized whether or not the virtues 3 are correctly set on the upper surface of the top plate 101 in a rotation preventing state. Therefore, it is even easier to use.

  Moreover, in this case, since the rotation of the virtues 3 is prevented at only one predetermined position on the upper end surface 141 of the top plate outer frame 14, the virtues 3 are correctly set on the upper surface of the top plate 101. It is possible to easily confirm whether or not Therefore, it is even easier to use.

  Further, in this case, the projecting piece 32 formed on the support claw 31 is fitted into the notch 42 in a state where the inner end surface 325 is in contact with the outer peripheral end surface 105 of the top plate 101. Since it is configured to be caught on the outer peripheral end surface 105 of the top plate 101, even if a stress is applied laterally from the side surface portion 104 side of the stove body 10 to the center side with respect to Gotoku 3, Gotoku 3 is burnered. It is hard to come off from 22 easily. Therefore, usability is even better.

  In the above-described embodiment, one specific support claw 31 (outer center claw 31A) of Gotoku 3 is configured to fit into the notch 42 on the upper end surface 141 of the top plate outer frame 14. However, like the gas stove 1E shown in FIG. 4, the support claw (outer front claw) 31B extending from the front side position of the lower frame 30 toward the side surface 104 side of the stove body 10 and the lower frame 30 A projecting piece 32 is provided at the lower part of either or both of the support claws (outer rear claws) 31C extending from the rearward position toward the side surface portion 104 side of the stove body 10, and the projecting pieces 32 are provided on the ceiling. It is good also as what was comprised so that rotation to the burner body 20 circumferential direction of Gotoku 3E might be prevented by engaging with the notch 42 provided in the upper end surface 141 of the board outer frame 14. FIG. Such a structure is provided on the extension line in the front-rear direction passing through the center of the lower frame 30 and on the extension line in the left-right direction passing through the center of the lower frame 30 as shown in FIG. Is particularly suitable for those not provided.

  In the above-described embodiment, the upper end surface 141 of the top plate outer frame 14 is provided with the notch 42 as the rotation preventing portion of the virtues 3. However, as in the gas stove 1F shown in FIG. A pair of clamping pieces 420 are provided on the upper end surface 141 of the outer plate frame 14 as a rotation preventing part of the virtues 3F, and the support claws 31 are fitted into the gaps 42F between the clamping pieces 420 so that the burner body of the virtues 3F. It is good also as what was comprised so that rotation to 20 circumferential directions might be prevented. Further, as in the gas stove 1G shown in FIG. 6, a pair of clamping pieces 320 is provided at the lower part of the support claw 31 of the virtues 3G, while the upper end surface 141 of the top plate outer frame 14 is provided as a rotation prevention portion of the virtues 3G. The projecting piece 42G may be provided, and the projecting piece 42G may be inserted into the gap 32G between the sandwiching pieces 320 to prevent the rotation of the virtues 3G in the circumferential direction.

  Moreover, in the said embodiment, although what was provided with the notch 42 as a rotation prevention part of the virtues 3 in the upper position of the side part 104 of the stove main body 10 in the upper end surface 141 of the top-plate outer frame 14 was demonstrated, A notch 42 may be provided as a rotation blocking portion of Gotoku 3 at a position above the rear surface of the stove body 10 on the upper end surface 141 of the top plate outer frame 14, or on the outer surface of the top plate outer frame 14, It is good also as what provided the notch and the protruding piece as a rotation prevention part of Gotoku 3.

  The present invention can also be applied to a structure in which an annular ridge 101C is formed along the outer periphery of the burner opening 15, instead of the burner ring 22, as in the gas stove 1H shown in FIGS. In this structure, the outer periphery of the annular raised portion 101C becomes an engaged portion that engages the lower frame 30, and the lower frame 30 is ring-engaged with the outer periphery of the annular raised portion 101C, so that the virtues 3 are attached to the burner body 20. On the other hand, it is positioned on the front, rear, left and right.

  Moreover, the present invention can be applied to a so-called built-in stove that is mounted in a stove-attached hole opened on a countertop of a kitchen in a state of being dropped, or can be applied to a gas stove that does not have the grill cabinet 100.
