Description

  The present invention relates to a glass top plate for a stove including a pin for positioning five virtues.

  Since the stove burns when the flame of the burner touches the virgin claws, it causes poor combustion, so there is no flame hole (no flame hole) on the peripheral surface of the burner with a circumferential interval equivalent to the circumferential arrangement pitch of the virgin 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 in a normal orientation 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 stove for a glass top plate, impacts such as when a cooking container such as a pan or a frying pan is moved violently are transmitted to the glass top plate through the virtues, and the glass top There is a risk of cracking the plate. In particular, in the case where the lower end of the leg of the virtuosity claw is in direct contact with the top plate, the virtuosity frame that connects the lower end of each leg is provided, and the top plate is in contact with the top plate in comparison with the virtuos that contact the top plate via the virtuosity frame. The impact area of the glass top plate is likely to decrease due to stress concentration.

  In view of the above points, an object of the present invention is to provide a glass top plate for a stove that can prevent the impact resistance of the glass top plate from being lowered.

  The present invention includes a glass top plate main body, a metal frame provided on the peripheral edge of the top plate main body, and a leg portion projecting on the top plate main body and extending below the five virtue claws constituting the five virtues. A glass top plate for a stove comprising a pin for positioning the five virtues by being fitted into a concave hole formed at the lower end of the top plate, wherein the pin is inserted into a through-hole formed in the top plate body, and above the top plate body And a flange projecting in parallel with the top plate body with an interval upward from the top surface of the top plate body. An elastic member is provided between the top plate body and the top plate body so as to liquid-tightly close the space between the top plate body, and the lower end of the leg portion of the virtuosity claw is seated on the flange at a portion around the concave hole. Arranged below the main body of the board with a space from the lower surface of the main body. Is provided with a coupling retention plate to the frame body, the holding plate is characterized in that supporting the pin from below.

  According to the present invention, when a cooking container such as a pot or frying pan on the virtues is moved violently, the impact is absorbed by the elastic member via the virtues and the flange of the pin, and via the holding plate that supports the pin. Is transmitted to the frame provided at the peripheral edge of the top plate body, and the impact force is dispersed. Thereby, it becomes difficult to transmit the said impact to the glass-made top-plate main body, and it can prevent that the impact resistance 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.

  Here, it is conceivable that the pin is fixed to the top plate in order to prevent the pin from falling off. As a fixing method, it is conceivable that a male screw portion is formed at the lower end portion of the pin, a through hole through which the male screw portion of the pin can be inserted is formed in the holding plate, and fixed with a nut. However, this requires a nut, increases the number of components, and lowers the ease of assembling the pins to the top plate.

  In this case, if the holding plate is provided with a screw hole corresponding to the through hole of the top plate body, the male screw portion provided on the pin is screwed into the screw hole of the holding plate, and the pin is fixed to the holding plate, Since the holding plate itself also functions as a nut, the nut becomes unnecessary, and the assemblability can be improved.

  Further, in the present invention, if the holding plate is formed so as to extend from the frame body and is integrated with the frame body, the connection strength between the holding plate and the frame body is increased, and the shock transmitted through the virtues and pins is It becomes easy to disperse by being directly transmitted to the glass, and the impact resistance of the glass top plate can be further improved.

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 glass top plate 1 is heated by the flame produced | generated by combustion of the air-fuel mixture which ejected.

  The virtues 2 have a central coupling portion 21 located above the burner 3 and a plurality (four in the present 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 claw 22 is set on the glass top plate 1 with a normal phase in which each virtuosity claw 22 is positioned in the same orientation as the flameless hole portion or the small flame hole portion of the burner 3, the flame touches each virtuosity claw 22. Can be prevented.

  Therefore, in the present embodiment, a pair of pins 5 is provided on the glass 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 two opposing virtuosity claws 22. Is formed, and the pin 5 and the concave hole 23a are fitted together, thereby positioning the virtues 2 on the glass 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. The pin 5 is formed with a stepped portion 52a by providing a small diameter portion 52 at the lower end. A screw is cut on the outer peripheral surface of the small diameter portion 52. That is, in the present embodiment, the small diameter portion 52 corresponds to the male screw portion of the present invention.

  Then, the pin 5 is inserted into the annular packing 6 made of an elastic resin such as silicone rubber from above, and the pin 5 is positioned at a position corresponding to the concave hole 23a for placing the virtues 2 on the top plate 1 in a normal phase.
