Description

  The present invention relates to a positioning structure for five virtues placed on a top plate of a stove.

The stove burns when the flame of the burner touches the five virtue claws, resulting in poor combustion. Therefore, there is no flame hole (no flame hole) on the circumferential surface of the burner with a circumferential interval equivalent to the circumferential arrangement pitch of the virtue claws. Part) and a small flame hole. Then, a pin is projected on the top plate so that each virtuosity claw can be set on the top plate with a normal phase located in the same orientation as each flameless hole portion or small flame hole portion of the burner. In order to position the five virtues, a concave hole formed at the lower end of the leg portion extending below the five virtue claws constituting the pin is known (see, for example, Patent Document 1). Thereby, it can prevent that the flame of a burner touches each virtue nail.
Japanese Patent No. 2698002

  When the conventional virtuosity positioning structure is applied to a glass top plate stove, the impact of moving a pan, pan, etc. is transmitted to the glass top plate through the virtues, and the durability of the glass top plate May decrease. In particular, in the case where the lower ends of the leg portions of the five virtue claws are in direct contact with the top plate, the top plate is provided with a frame portion that connects the lower ends of the leg portions and compared with the five virtue that contacts the top plate via the frame portion. The contact area is small, and the durability of the glass top plate tends to decrease.

  An object of this invention is to provide the positioning structure of five virtues which can prevent that durability of a glass top plate falls in view of the above point.

  In order to achieve the above-mentioned object, the present invention is adapted to a pin projecting on the top plate of a stove by fitting a concave hole formed at the lower end of a leg portion extending below the five virtue claws constituting the five virtues. In the positioning structure of five virtues for positioning, the top plate is made of glass, and the pin is inserted into a through hole formed in the top plate and protrudes above the top plate. A flange projecting in parallel with the top plate is provided with a gap, and an elastic member is provided between the flange and the top plate so as to liquid-tightly seal between the flange and the top plate. It is characterized in that it is seated on the flange around the hole.

  According to the present invention, an impact such as when a pan or the like on the virtues is moved is absorbed by the elastic member via the virtues and the flange of the pin, and is hardly transmitted to the glass top plate. Thereby, it can prevent that the durability of a glass top plate falls. Further, since the elastic member closes the gap between the flange and the top plate in a liquid-tight manner, it is possible to prevent the simmered juice or the like from flowing into the stove from the gap between the pin and the through hole of the top plate.

  In the present invention, the virtues are provided with a plurality of virtues, and a plurality of pins projecting from the top plate so as to correspond to all the virtues are fitted with pins corresponding to the lower ends of the leg portions of the virtues. If the concave hole is formed, the impact from all the five virtue claws can be absorbed by each elastic member, and the lowering of the durability of the top plate can be more reliably prevented.

  Further, in the present invention, the five virtues are provided with a plurality of five virgin claws, and a pin is protruded from the top plate so as to correspond to some of the five virgin claws. If a concave hole is formed and a cushion member is provided at the lower end of the leg portion of the other five virtue claws, the other virtue can be used with the cushion member without projecting pins corresponding to all the five virtue claws on the top plate. The impact from the nail can be absorbed, and the durability of the top plate can be prevented from being lowered.

  Hereinafter, with reference to FIGS. 1-3, embodiment of the positioning structure of five virtues of this invention is described using a drop-in type gas stove. In the figure, reference numeral 1 denotes a glass top plate of a gas stove, and 2 denotes five virtues placed on the top plate 1. An opening 1a is formed in the top plate 1, and a burner 3 protrudes upward from the opening 1a.

  As shown in FIG. 2, the burner 3 is mounted on the mixing tube 31 installed in the stove body 4 covered with the top plate 1, the burner body 32 protruding above the top plate 1, and the burner body 32. And a burner head 33.

  The mixing tube 31 is placed and fixed on a frame 4 a provided on the bottom of the stove body 4. A gas nozzle (not shown) facing the upstream end of the mixing tube 21 is provided in the stove body 4. A mixed gas (air mixture) of the fuel gas ejected from the gas nozzle and the primary air sucked from the upstream end of the mixing pipe 31 is generated in the mixing pipe 31. The downstream end portion of the mixing tube 31 is bent upward, and a cylindrical portion 34 suspended from the burner body 32 is fitted to the downstream end portion from above. A gap between the opening 1a of the top plate 1 and the downstream end of the mixing tube 31 is closed by a lid 1b.

  A large number of tooth forms are suspended from the outer peripheral portion of the lower surface of the burner head 33, and a flame hole 35 is formed by gaps between these tooth forms. The air-fuel mixture from the mixing tube 31 is ejected from the flame hole 35 through the burner body 32. And the to-be-heated object mounted in the virtues 2 on the top plate 1 is heated by the flame produced | generated by combustion of the jetted air-fuel mixture.

  The virtues 2 include a central coupling portion 21 located above the burner 3 and a plurality (four in this embodiment) of five virgin claws 22 extending radially outward from the central coupling portion 21. A leg portion 23 extending downward is formed at the outer end portion of each of the five virtue claws 22. A concave hole 23 a is provided at the lower end of the leg portion 23.

  By the way, when the flame of the burner 3 touches the five virtue claws 22, a combustion failure occurs. Therefore, a flameless hole portion (a portion without the flame hole 35) or a small flame hole portion is provided on the peripheral surface of the burner head 33 with a circumferential interval equivalent to the circumferential arrangement pitch of the five virtue claws 22 provided. Therefore, if each virtuosity 22 is set on the top plate 1 in a normal phase in which each virtuosity claw 22 is positioned in the same orientation as each flameless hole portion or small flame hole portion of the burner 3, each virtuosity claw 22 touches the flame. Can be prevented.

  Therefore, in the present embodiment, a pair of pins 5 are projected from the top plate 1 so as to correspond to the two opposing virtuosity claws 22, and the pins 5 corresponding to the lower ends of the leg portions 23 of the opposing two virtuosity claws 22 The concave hole 23a to be fitted is formed and the pin 5 and the concave hole 23a are fitted to position the virtues 2 on the top plate 1 in a normal phase. This will be described in detail below.

  As shown in FIG. 3, the pin 5 includes a flange 51 projecting radially outward provided in the middle in the up-down direction, and a small-diameter portion 52 provided at the lower end portion with a space downward from the flange 51. Is provided. A screw is cut on the outer peripheral surface of the small diameter portion 52. Then, the pin 5 is inserted into the annular packing 6 made of an elastic resin such as silicone rubber from above, and is positioned at a position corresponding to the concave hole 23a when the virtues 2 are placed on the top plate 1 in the normal phase. Are inserted into the through holes 11 provided in the top plate 1. At this time, the packing 6 is positioned between the lower surface of the flange 51 of the pin 5 and the upper surface of the top plate 1. That is, in the embodiment, the packing 6 is an elastic member of the present invention.

  The nut 7 is screwed to the small diameter portion 52 of the pin 5. An annular packing 81 and a washer 82 are interposed between the lower surface of the top plate 1 and the upper surface of the nut 7. By tightening the nut 7, the packing 6 is sandwiched between the flange 51 and the top plate 1. As a result, the packing 6 liquid-tightly closes the gap between the flange 51 and the top surface of the top plate 1. Therefore, it is possible to prevent boiled sap from flowing into the stove body 4 through the gap between the pin 5 and the through hole 11 of the top plate 1.

  The distance between the flange 51 of the pin 5 and the small diameter portion 52 is set slightly longer than the thickness of the top plate 2, that is, the axial length of the through hole 21. This prevents the top plate 1 from being damaged by overtightening the nut 7. In addition, a pair of parallel chamfered portions 53 are formed in a portion located above the flange 51 of the pin 5, thereby making it easy to prevent the pin 5 from rotating and to easily tighten the nut 7.

  The lower end of the leg portion 23 of the virtuosity claw 22 is seated on the flange 51 of the pin 5 at a portion around the concave hole 23a. A cushion member 9 having elasticity such as silicone rubber is provided at the lower end of the leg portion 23 of the other two virtuosity claws 22 except for the two virtuosity claws 22 in which the recessed holes 23a are formed. The leg portions 23 of 22 are seated on the top plate 1 through the cushion member 9.

  According to the gas stove of the embodiment, an impact such as when a pan or the like on the Gotoku 2 is moved is absorbed by the packing 6 or the cushion member 9 through the Gotoku claws 22 and the flange 51 of the pin 5, and is made of glass. It becomes difficult to be transmitted to the top plate 1. Thereby, it can prevent that durability of the glass-made top plate 1 falls.

  In addition, although embodiment demonstrated the thing which provided the concave hole 23a in the leg part 23 of the two five virtue claws 22 among the four virtue claws 22, it is a concave hole in the leg part 23 of the three or all five virtue claws 22. 23a may be provided, and the top plate 1 may be provided with a pin 5 corresponding to the recessed hole 23a. A spring washer may be used in place of the packing 81 and the washer 82 positioned between the lower surface of the top plate 1 and the nut 7.
