  The virtues 300 have an engaging portion 330 that can be engaged with the positioning portion 222. The engaging portion 330 is provided at the distal end portion of the five virtue claws 320 and protrudes downward from the portion of the connecting portion 310 to which the virtue claws 320 are connected. When the virtues 300 are placed on the top plate 15, the engaging portions 330 are engaged with the positioning portions 222 disposed above the flame holes 204, whereby the burners 201 and the top plate 15 are engaged. Positioned against. In the present embodiment, six positioning portions 222 are provided so as to be aligned in the circumferential direction, but the number of positioning portions 222 can be arbitrarily changed.

  The positioning portion 222 provided in the burner 201 is directed from the locking portion 223 recessed in the upper end surface 221 and the top portion 224 disposed between the two locking portions 223 arranged in the circumferential direction toward the locking portion 223. And two inclined guide surfaces 225 that are inclined so as to be lower. That is, the inclined guide surface 225 is inclined along the circumferential direction of the cover member 220.

It is preferable to dispose the locking portion 223 at a position separated from the flame hole 204b.

Next, the operation of the gas stove 200 of the present embodiment will be described.
When placing the virtues 300 on the top plate 15, as shown in FIG. 2, the insertion holes 311 formed in the connecting portion 310 of the virtues 300 are fitted into the temperature sensor 230. Then, by virtue of its own weight, the virtues 300 move downward while being guided by the inclined surface 234 of the temperature sensor 230 through the insertion hole 311, and the connecting portion 310 is disposed on the cover member 220.

  In this state, when the virtues 300 are rotated about the central axis of the annular connecting portion 310, the engaging portion 330 protruding from the lower surface side of the connecting portion 310 is inclined on the upper end surface 221 of the cover member 220. It moves along the guide surface 225. And when the engaging part 330 provided in the connection part 310 engages the latching | locking part 223 provided in the burner 201, the virtues 300 will be attached on the top plate 15 in the state positioned with respect to the burner 201. .

  At this time, in the virtues 300, the engaging portion 330 is engaged with the engaging portion 223 in a concave-convex relationship so that rotation in the circumferential direction is restricted, and the inclined engaging surface 313 is inclined and guided by its own weight. The surface is in surface contact with the surface 225 and is supported by the burner 201. Thus, when the virtues 300 are positioned with respect to the vertical direction and the circumferential direction, the inclined engagement surface 313 is brought into surface contact with the inclined guide surface 225 by its own weight, so that the posture is stabilized.

According to the embodiment detailed above, the following effects are exhibited.
(1) Since the positioning part 222 with which the engaging part 330 of the virtues 300 engages is provided in the burner 201, positioning the virtues 300 with respect to the burner 201 does not provide the top plate 15 with an uneven shape. The five virtues 300 can be positioned with respect to the top plate 15. In addition, since the positioning portion 222 is disposed above the flame hole 204 provided in the burner 201, even if the lower portion of the burner 201 or the top plate 15 becomes dirty due to boiling or the like, the positioning portion 222 becomes dirty. It is hard to stick. Therefore, since the problem that dirt adheres to the positioning part 222 and the positioning of the virtues 300 becomes difficult to occur, the virtues 300 can be easily positioned. Thereby, the virtues 300 can be easily positioned without providing the top plate 15 with an uneven shape.

  (2) Since a plurality of positioning portions 222 are arranged so as to be aligned in the circumferential direction, the engagement portion 330 engages with the positioning portion 222, whereby the virtues 300 can be positioned in the circumferential direction. And since the engaging part 330 is provided in the front-end | tip part of the 5 virtue claw 320, even if it does not visually recognize the engaging part 330 directly, the position of the engaging part 330 in the circumferential direction can be seen by visually recognizing the 5 virtue claw 320. While grasping, positioning of the virtues 300 can be performed.

  (3) Since the positioning portion 222 provided on the cover member 220 has the inclined guide surface 225 that is inclined along the circumferential direction of the cover member 220, the connecting portion 310 of the virtues 300 is placed on the cover member 220 and the virtues. When 300 is rotated in the circumferential direction, the inclined engagement surface 313 of the virtues 300 overlaps with the inclined guide surface 225. Thereby, since the inclined engagement surface 313 and the inclined guide surface 225 are brought into surface contact by the own weight of the five virtues 300, the five virtues 300 placed on the top board 15 can be stabilized.

  (4) By fitting the engaging portion 330 projecting from the connecting portion 310 of the virtues 300 into the engaging portion 223 recessed in the upper end surface 221 of the burner 201, the virtues 300 in the direction intersecting the vertical direction Movement can be regulated. And since the latching | locking part 223 is formed in the upper end surface 221 of the burner 201, when positioning the virtues 300, it is easy to visually recognize. Further, since the engaging portion 330 protrudes downward from the connecting portion 310 that connects the plurality of virgin claws 320, the top plate is supported by the positioned connecting portion 310 being supported by the upper end surface 221 of the burner 201. 15 can be stabilized.

  Further, by stabilizing the virtues 300 placed on the top plate 15, the contact area between the base end of the virtuosity claw 320 and the top plate 15 can be reduced, so that the dirt attached to the top plate 15 is Adhesion to the nail 320 can be suppressed.

  (5) When the top surface 231 of the temperature sensor 230 is inserted through the insertion hole 311 of the virtues 300, the virtues 300 move downward along the inclined surface 234, and therefore toward the positioning portion 222 provided on the cover member 220. The engaging portion 330 provided in the connecting portion 310 can be guided. Thereby, the engaging part 330 can be easily engaged with the positioning part 222.

  (6) By making the cover member 220 detachable from the burner head 210, the cover member 220 can be detached from the burner head 210 and the positioning portion 222 can be easily cleaned.

  (7) Since the outer edge of the cover member 220 protrudes outward from the cylindrical portion 211 in which the flame hole 204 is formed, the cover member 220 prevents the burner head 210 from being attached to the flame hole 204. Can be protected.

  (8) By disposing the locking portion 223 at a position separated from the main flame hole 204b, it is possible to prevent a large flame coming out from the main flame hole 204b from hitting the five virtue claws 320. Thereby, the fall of the thermal efficiency at the time of heating the pan etc. which are mounted on Gotoku 300 can be suppressed.

In addition, the said embodiment can also be changed and actualized as follows.
-As shown in FIG. 4, you may provide the flange part 314 used as the aspect which protrudes toward the top plate 15 side at the time of positioning in the outer edge of the connection part 310 of Gotoku 300.

While being able to suppress, aesthetics can be improved.

The inclined engaging surface 313 and the inclined guiding surface 225 may not be provided, and the connecting portion 310 may be supported by the locking portion 223 via the engaging portion 330.
-In the connection part 310, you may provide the engaging part 330 in the position spaced apart from the five virtue claw 320. FIG. According to this structure, since the engaging part 330 can be arrange | positioned in arbitrary positions, the freedom degree of design can be made high.

  -When the virtues 300 are placed on the top plate 15, the connecting portion 310 may be provided at a position away from the burner 201. For example, the base end portion of the five virtue claws 320 can be connected to the connecting portion 310. Also in this case, the virtues 300 can be positioned by locking the engaging portions 330 projecting downward from the front end portions of the virtues 300 to the locking portions 223.

  -The engagement part 330 and the latching | locking part 223 should just be provided at least 1 each. However, when a plurality of engaging portions 330 and locking portions 223 are provided, the virtues 300 can be positioned more accurately than when only one engaging portion 330 and one locking portion 223 are provided. This is preferable because it is possible.

  The burner 201 may be configured not to include the temperature sensor 230. In this case, since it is not necessary to provide the insertion hole 311 in the connection part 310 of the virtues 300, the configuration of the virtues 300 can be simplified.

  The burner 201 may be configured not to include the cover member 220. According to this configuration, the configuration of the burner 201 can be simplified. Also in this case, the positioning of the virtues 300 can be performed by forming a positioning portion on the upper end surface of the burner head 210. Alternatively, instead of the cover member 220, a secondary air guide that forms a ventilation gap for secondary air between the upper surface of the burner head 210 may be provided, and a positioning portion may be provided on the upper end surface of the secondary air guide. Good.

  -While the latching | locking part which comprises a positioning part is protrudingly provided in the upper end surface 221 of the burner 201, an engaging part may be recessedly provided in Gotoku 300. FIG. According to this structure, it can suppress that a latching part accumulates dirt compared with the case where the latching | locking part is recessed.

  The connecting part 310 of the burner head 210 and the virtues 300 is not limited to the outer edge formed in a circular shape, and for example, the outer edge may be formed in a circular shape having a polygonal shape, or in a linear shape that does not form a ring. It may be formed.
