The present invention relates to trivets used in stoves.

In furnaces, such as a gas stove, the method of forming a protective layer, such as an enamel and a fluorine coating, on the upper surface of a top plate is used well in order to prevent the boiling soup etc. adhering to the upper plate which covers the opening of the upper surface of a furnace main body. In addition, the iron trivet is placed on the top plate, and if it is scratched by the trivet, the upper surface of the top plate is damaged. In particular, scratches are likely to occur in the upper plate having the protective layer formed on the upper surface thereof.

Therefore, it is known that a recess is formed on the bottom of the trivet, and it is attached by inserting a heat-resistant buffer (packing) in the recess, thereby preventing the top plate from being scratched by the trivet (for example, a patent document) 1).

Japanese Patent Application Laid-open No. Hei 10-300104 {bush 45 in FIG. 1}

However, only by inserting the buffer into the concave portion of the bottom of the trivet, the buffer easily slips out when the buffer is strongly rubbed, and when the buffer is pulled out, the upper plate cannot be prevented from scratching, and the trivet is rattling. In addition, iron trivets tend to transmit heat, and the buffer may transfer heat to deteriorate or melt. The durability of the buffer may also be insufficient, and this may cause the buffer to fall out.

Accordingly, an object of the present invention is to improve durability by preventing the buffer from falling out and preventing the performance degradation caused by the heat of the buffer in the trivet provided with the heat resistant buffer at the bottom.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention is a trivet used for a stove, In the trivet which a heat resistant buffer body is protruded and attached to the recessed part formed in the bottom face of the trivet from this bottom face, The said buffer body is the said A heat insulating material is interposed on the upper surface of the concave portion, and the concave depression formed on the bottom surface of the buffer member is attached to the concave recess by a screw to which the head is buried.

The trivet consists of a plurality of protrusions and a frame connecting them, and the bottom of the trivets having the concave portion may be either the bottom of the protrusion or the bottom of the frame.

In the present invention, since the heat-resistant buffer is screwed into the concave formed on the bottom of the trivet, even if the buffer is strongly rubbed, it does not fall out, and the top plate can be stably prevented from being damaged by the buffer. The sieve will not fall out and cause trivet rattling. In addition, since the buffer is attached to the recess of the bottom of the trivet through the heat insulating material, it is possible to reduce the transfer of heat of the trivet to the buffer, thereby preventing the performance degradation caused by the heat of the buffer to have high durability. Can be.

According to the present invention, the shock absorber can be attached to the recess in point contact with the gap between the inner sidewall of the recess and the gap. As a result, it is possible to further reduce the heat transfer to the buffer, and to prevent the performance degradation caused by the heat of the buffer. The buffer is positioned in the recess if the contact with the inner sidewall is point contact. In particular, when the screw is fixed, the buffer is positioned without rotation.

In addition, the upper surface of the buffer body is provided with a receiving portion for accommodating the lower portion of the heat insulating material, the lower portion of the heat insulating material accommodated in the receiving portion can be a shape that does not rotate in contact with the inner side wall of the receiving portion. In this way, the heat insulating material adhering to the concave portion is hardly seen from the outside so that the external appearance is not damaged, and the position of the heat insulating material can be prevented from shifting from the buffer body when the buffer is attached.

Further, a ceiling surface receiving portion for accommodating an upper portion of the heat insulating material may be formed on the ceiling surface of the recess, and an upper portion of the heat insulating material accommodated in the ceiling surface receiving portion may contact the inner sidewall of the ceiling surface receiving portion so as not to rotate. . By doing in this way, the heat insulation material attached to the recessed part becomes hard to be seen from the outside, and external appearance is not damaged, and the position on the heat insulating material at the time of attachment of a buffer body can be prevented from shifting in a recessed part.

Further, a plurality of protrusions can be formed on the lower surface of the side wall forming the concave depression of the bottom of the buffer. This makes it possible to prevent the trivet from slipping well against the top plate, and to reduce the transfer of heat from the top plate to the buffer, thereby further improving the effect of preventing performance degradation due to the heat of the buffer.

In one embodiment of the present invention, the trivet consists of a plurality of radially long stone claws and a frame connecting the claws, and the recess formed on the bottom of the claws has both sides in the longitudinal direction of the claws opened. As the notch groove, a water penetration prevention portion is formed at the upper edge of the opening of the notch groove. If the water penetration prevention part is formed, even if a large amount of broth has fallen to the stone piece, the broth will fall down while riding on the water penetration prevention part, so that the insulation does not enter the recess from the outer surface of the stone piece so that the insulation gets wet by the soup. There is no work.

The space | interval G of is formed. In addition, the base 19c of the guide member 19 is attached to the support 12d attached to the burner 11 while maintaining the distance T with the burner 11, and the burner 11 and the guide member 19. Air flows between) and guides the flame further toward the center.

The trivet 20 is composed of six radially long protrusions 21 and an annular trivet edge 22 connecting them, and the tricycle of each protrusion 21 is radially outward from the edge 22. The heat resistant buffer body 24 is attached to the recessed part formed in the bottom face of 21 A of protruding leg parts. The trivet 20 is placed on the top plate 13 by landing the buffer member 24 attached to the recessed portion of the bottom surface of the protrusion piece 21 on the top plate (13).

The bottom surface of the trivet rim 22 is formed with a protruding ring portion 22a protruding downward, and a sunshade 22b protruding into the front circumference is formed at the base of the protruding ring portion 22a. When the trivet 20 seats on the upper surface of the glass plate 13a of the upper plate 13, the protrusion ring portion 22a is allowed to enter the gap G. By this, the trivet 20 is positioned, and the trivet rim 22 is positioned on the inner side of the tip of the diffuser 19b of the guide member 19, and the trivet rim 22 is positioned outside the trivet rim 22. Since the periphery is located outside the protective ring 16, the boiled broth formed during cooking by covering the gap G does not fall into the gap G even when the trivet falls to the edge 22.

According to this embodiment, as shown in FIG. 2, FIG. 4, and FIG. 5, the bottom surface of the leg part 21A of the protrusion piece 21 of the trivet 20 is made into the outer end 21G of the protrusion piece 21, and The inner end 21N is cut out at right angles to the longitudinal direction of the radial direction, so that the recess 21B is formed as a notched groove opening to the left and right outer surfaces 21C in the longitudinal direction of the protrusion piece 21; In addition, the screwing hole 21B2 was formed in the ceiling surface 21B1 of this recessed part 21B. Then, the heat-resistant buffer 24 is disposed in the recess 21B via the heat insulating sheet 25 as a heat insulating material, and the head portion 26a is formed in the recessed recess 24B of the lower surface of the buffer 24. The shock absorber 24 and the heat insulating sheet 25 were fixed to the screwing hole 21B2 of the ceiling surface 21B1 of the recessed part 21B by the screw 26 to which it was buried.

At this time, the upper surface 24U of the buffer body 24 does not contact the ceiling surface 21B1 of the recess 21B by the heat insulating sheet 25. In addition, since the lower portion 24K of the buffer member 24 protrudes from the bottom surface of the leg portion 21A of the protrusion piece 21 by a predetermined height H, even when the trivet 20 is placed on the top plate 13, the trivet Since it is the buffer 24 which the 20 contacts, the upper plate 13 does not cause a damage | wound.

Moreover, the said buffer body 24 is a small rectangle which does not contact this inner side wall 21B3, in order to remove the heat transfer by the contact with the inner side wall 21B3 of the recessed part 21B of the protrusion piece 21. It formed in the shape and adhere | attached at intervals with the inner side wall 21B3.

In addition, when the contact with the inner sidewall 21B3 is in point contact, the buffer 24 has almost no heat transfer from the trivet, so that the buffer 24 is in point contact with the inner sidewall 21B3, for example, FIG. 5. As shown by broken lines in (b), the inner sidewall 21B3 is arcuate, and only the corners of the rectangular buffer 24 are in point contact with the inner sidewall 21B3. As shown, the structure which makes the protrusion 28 which protrudes inwardly from the inner side wall 21B3, and makes point contact, or the protrusion which protrudes outward from the side surface of the buffer body 24, as shown to FIG. 5 (d). (29) may be formed so that the buffer body 24 and the inner sidewall 21B3 may be in point contact. In this way, the buffer 24 is positioned in the recess 21B. In particular, the buffer 24 is positioned so that it does not rotate when the screw is fixed.

Silicone rubber (heat resistance temperature 300 degreeC) was used as the heat resistant buffer 24, and the nonwoven fabric of ceramic wool was used as the heat insulating sheet 25. As shown in FIG.

Further, preferably, a rectangular accommodating portion 24A is formed on the upper surface of the buffer 24, and the lower half of the heat insulating sheet 25 is accommodated and supported in the accommodating portion 24A. In this case, the heat insulating sheet 25 attached to the recess 21B is not easily seen from the outside and the appearance is not impaired, and the position of the heat insulating sheet 25 at the time of attachment of the buffer 24 is changed to the buffer. The shift from (24) can be prevented.

And in this embodiment, the accommodating part 24A of the upper surface of the buffer body 24 is the side which positions the side wall 24A1 which forms this accommodating part 24A in the opening of both sides of the recessed part 21B, ie The side of the both side surfaces 21C of the leg portion 21A is left, and the side facing the pair of inner sidewalls 21B3 of the recess 21B is cut out to form the notch portion 24A2.

In addition, positioning of the heat insulating sheet 25 with respect to the buffer 24 is performed on the side surface 25A1 of the heat insulating sheet 25 with respect to the side wall 24A1 constituting the receiving portion 24A for the heat insulating sheet 25. ) Is positioned so that the heat insulating sheet 25 does not rotate inside the housing portion 24A.

Moreover, as shown by the dotted line in FIG. 5 (a) in the ceiling surface 21B1 of the recessed part 21B, the ceiling surface accommodating part 21B4 which accommodates the heat insulating sheet 25 is formed, and a ceiling surface accommodating part The upper part of the heat insulating sheet 25 accommodated in 21B4 can be made into the shape which touches the inner side wall of the ceiling surface accommodating part 21B4, and does not rotate.

By doing in this way, since the heat insulating sheet 25 adhering to the recessed part 21B becomes hard to be seen from the outside, an external appearance is not impaired and at the time of attachment of the buffer 24, the position of the heat insulating sheet 25 is Offset in the recess 21B can be prevented.

Moreover, the recessed recessed part 24B of the lower surface of the buffer body 24 leaves the side wall 24B1 which forms the recessed recessed part 24B, and the notch part 24A2 on the same side as the notch part 24A2 of the accommodating part 24A. When the side opposite to 24A2 at right angles is cut out to form the notch portion 24B2, the shape of the shock absorber 24 is balanced and the deformation of the shock absorber 24 when the screw 26 is tightened can be prevented. have. 24C is a hole for the screw 26.

Moreover, although the accommodating part 24A was made into the groove-shaped accommodating part between two side walls 24A1 which oppose, it can also be set as the recessed part surrounded by four sides by the side wall 24A1. Moreover, although the recessed recessed part 24B was also made into the groove-shaped recessed recessed part by the notch part 24B2, it can also be set as the recessed recessed part surrounded by four sides by the side wall 24B1.

Since the trivet of this embodiment is comprised as mentioned above and the heat-resistant buffer 24 was screwed into the recessed part 21B formed in the bottom face of the protrusion piece 21 of the trivet 20, the buffer 24 was carried out. It is possible to stably prevent the wound of the upper plate 13 by the buffer 24, even if it is strongly rubbed, and also cause the trivet 20 to rattle due to the buffer 24 being pulled out. Disappear. The buffer 24 is also attached to the inner side wall 21B3 in the recess 21B at a point contact or spaced apart through the heat insulating sheet 25 so that the trivet 20 and the buffer 24 have a large area. ), The transfer of heat from the trivet 20 to the buffer 24 can be reduced, and deterioration due to heat of the buffer 24 can be eliminated to achieve high durability.

In addition, although the temperature of the protrusion 21 of the trivet 20 may reach up to 270 degreeC, according to the attachment of the buffer of this embodiment, 220 degreeC which reduced the temperature of the buffer 24 about 50 degreeC Since it raises only to an extent, deterioration of a buffer can be fully prevented.

6 (a) and 6 (b) show another embodiment, in which the water penetrating prevention protrusion piece 21D is integrally formed at the upper edge of the opening of the recess 21B of the outer side surface 21C of the protrusion piece 21. It formed so that the heat insulating sheet 25 might be covered by this protrusion piece 21D. The protrusion pieces 21D are formed at intervals from the buffer body 24 in order to avoid heat transfer to the buffer body 24. As a result, even if the amount of the boiled soup dropped on the stone piece 21 is large, since the boiled soup falls through the stone piece 21D, the boiled soup is dropped into the recess 21B from the outer surface 21C of the stone piece 21. There is no work, and the heat insulating sheet 25 does not get wet by boiling soup.

Moreover, as shown in FIG.6 (c), the projection 27 is formed in four corners on the lower surface of the heat resistant buffer body 24. As shown in FIG. The protrusion 27 can be formed by integral molding with the buffer 24. As a result, as shown in FIG. 6B, the protrusions 27 on the lower surface of the buffer body 24 abut against the upper plate 13 so that the trivet 20 does not slide well against the upper plate 13. In addition, transfer of heat from the upper plate 13 to the buffer 24 can be reduced, and the effect of preventing deterioration due to heat of the buffer 24 can be further improved.

In the above embodiment, the concave portion 21B of the trivet 20 is rectangular in plan view, but can be a suitable shape. Since the trivet 20 is of the type which lands on the top plate 13 by the leg portion 21A of the protrusion piece 21, a recess is formed at the position of the leg portion at the bottom of the protrusion piece 21 to form a buffer (24). In the trivet of the type in which the trivet rim lands on the upper plate 13 on the outside of the protection ring 16 of the opening circumferential portion 13c of the upper plate 13, the tricycle forms a recess in the bottom of the rim and cushions it. Just attach a sieve.

In addition, although the trivet of the drop recognition furnace which used the glass top plate was demonstrated as an example, the top plate may use the metal plate, such as aluminum. In addition, the furnace is not limited to the drop-in type but may be a type provided above. The gas burner may be either external or flame resistant.

As is clear from the above description, the present invention can provide a trivet with which the heat resistant buffer attached to the lower surface is prevented from falling out and the heat transfer to the buffer is reduced to increase the durability of the buffer.
