The present invention relates to a cooking gas stove.

As a conventional gas stove, there is a case in which the upper part of the main furnace body accommodating the gas burner is covered by the upper plate, and a trivet is placed around the opening of the furnace which is formed to face the gas burner on the upper plate (for example, See Patent Document 1).

In such a gas stove, since the trivet is always in contact with the upper surface of the upper plate, there is a problem that the upper surface of the upper plate that the trivet is in contact with is damaged. That is, the trivet not only supports a relatively heavy cooking vessel, such as a pot of food, but also receives a high heat from the gas burner, so that the metal is relatively hard and heavy (eg, cast iron, etc.). It is formed to improve the strength and durability by preventing contact wear and deformation with the cooking vessel. On the other hand, in recent years, in order to improve the appearance, a glass top plate or an aluminum top plate may be adopted. When the trivets as described above are placed on these top plates, scratches or the like may occur on the top surface of the top plate, thereby causing the appearance of the top plate. There was a problem of damaging.

In addition, in other conventional gas furnaces, it is known that so-called flame-retardant burners having a plurality of inward flame holes are employed in an annular burner body having the same center as the furnace opening as a gas burner (for example, , Patent Document 2).

In such a gas stove, an annular guide member is provided on the burner body with the upper surface of the burner body to divide the air passage for secondary air, and a trivet is placed on the upper end of the guide member located inside the furnace opening. By placing, the trivet can be supported in a state of being lifted from the top plate. According to this, since a space | gap is formed between a trivet and a top board, compared with the case where a trivet is directly put on a top board, damage to the top board by contact of a trivet and a top board can be suppressed.

However, in the above-described gas stove having a flame retardant burner, since the tricycle is supported by the upper end of the guide member located inside the furnace opening, that is, since the support position is located at the innermost side of the trivet, the stability is low. Relatively low. For this reason, when cooking a cooking vessel such as an iron pot or a frying pan, the trivet cannot maintain its horizontal state and tilts in one direction. In some cases, a misalignment occurs in the furnace opening. There is a thing. In addition, when the position of the trivet is large, the engagement between the upper end of the guide member and the trivet may be released. At this time, the trivet does not remain in an excited state on the upper plate and comes into contact with the upper surface of the upper plate, thereby damaging the appearance of the upper plate. There is a fear.

The present invention has been made in view of the above problems, it is possible to improve the stability of the trivet and to maintain the state of lifting the trivet from the top plate during cooking, and to suppress the contact of the trivet and the top plate due to the misalignment of the trivet to damage the top plate. An object of the present invention is to provide a gas stove that can prevent the gas.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention has a furnace furnace body, the gas burner installed in a furnace furnace body, the top plate which has a furnace opening part which faces the gas burner, and covers the upper surface of the furnace body, and the perimeter of a furnace opening part A gas stove having a metal trivet placed on the gas stove, characterized in that a metal trivet is provided between the periphery of the furnace opening and the trivet to support the trivet in a state where the trivet is lifted from the top plate. have.

According to the present invention, the trivet is provided with a support ring, that is, the trivet is supported on the support ring by the trivet so that the trivet is kept in an excited state on the top plate. Thereby, compared with the case where a trivet is directly put on a top board, damage to a top board by contact of a trivet and a top board can be prevented. In addition, since the tricycle support ring is interposed between the periphery of the furnace opening and the tricycle, the tricycle can be supported at a position outside the furnace opening, and as a result, when the tricycle support is supported by a guide member in a conventional flameproof burner. In comparison with this, stability can be improved. Therefore, not only the state which lifted up the trivet from the top board during cooking can be kept good, but also unnecessary tilt and positional shift of the trivet can be suppressed.

In addition, since the tricycle support ring is formed separately from the tricycle, the tricycle does not need to form the support ring with the same material as the tricycle, and the tricycle can be easily lightened by forming the support ring using a metal that is lighter than the tricycle. . In addition, since the top plate is very easy to attach and detach, the trivet can be easily and quickly cleaned and replaced when the support ring is contaminated or damaged. Moreover, since the trivet does not have to be a dedicated part itself, It becomes cheap by being obtained.

In addition, in the present invention, the trivet is composed of a plurality of trigeminal doljo and the annular trigeminal frame connecting these trigeminal doldol, the trivet is located on the periphery of the furnace opening, the tricycle support ring is the upper end of the trigeminal frame It is preferable to support the trivet in contact with the lower surface.

According to this, the tricycle cannot be easily recognized from the outside because the tricycle is hidden under the frame of the tricycle, so the tricycle can be provided with the support ring without deteriorating the appearance, and the tricycle is lifted from the top plate. I can support it.

And, when the three ends of the three prongs of the three prongs are connected to the three prongs of the three prongs, and the three prongs of the three prongs of the three prongs extend outward of the frame at intervals between the upper end of the upper plate and the third prongs, ), A protruding member formed of a metal having a lower hardness than the trivet and protruding toward the upper surface of the upper plate may be attached in a non-contact state with the upper surface of the upper plate.

The protruding member is not in contact with the upper surface of the upper plate when the trivet is in a horizontal state, so that the upper plate is not damaged. In addition, in the case where the trivet is cooking to handle a cooking vessel such as an iron pot or a frying pan from above, when the trivet is inclined unnecessarily, the protruding member abuts against the top plate, thereby minimizing the inclination of the trivet, thereby reliably deviating the position of the trivet. It can prevent. When the trivet is inclined, the inclination of the trivet is suppressed by the protruding member so that the trivet returns to the horizontal state immediately by its own weight. As a result, the time for which the protruding member is in contact with the upper plate becomes very short, thereby preventing damage to the upper plate. can do. Further, since the protruding member is formed of a metal having a lower hardness than the trivet, damage to the upper plate can be made very small as compared with the case where the triangular protrusion contacts the upper plate.

In addition, in the present invention, the trivet support ring may form a vent hole through which the combustion air of the gas burner may pass.

According to this, even if the introduction of the combustion air from the outer periphery of the main body (for example, the rear end of the top plate or the front part of the main body) is insufficient, the tricycle can supply sufficient combustion air to the gas burner through the support ring. The combustion of the gas burner can be made favorable.

In addition, in the present invention, the trivet support ring extends downward along the periphery of the furnace opening from the inner periphery of the placement surface placed on the upper plate along the periphery of the furnace opening, and the inner periphery of the placement surface. The lower part, the standing part standing up from the outer periphery of the mounting surface part, and the supporting surface part extending horizontally or almost horizontally outward from the upper edge of the standing part to support the trivet. Characterized in having a.

When the trivet having such a shape is attached to the furnace opening of the upper plate, positioning of the mounting surface portion on the upper plate is easy by only inserting the drooping portion into the furnace opening. Since is supported, it is possible to obtain a support state of high stability trivet.

In addition, the tricycle is composed of a plurality of trigeminal doljo and the annular trigeminal frame connecting the trigeminal doljo, the tricycle support ring when the support surface portion of the support ring abuts the lower surface of the trigeminal frame, the tricycle support ring There is formed a plurality of the standing portion and the support surface portion at predetermined intervals along the outer periphery of the mounting surface portion, and forms a engaging recess that the outer end of the support surface portion is engaged with the tricycle of the trivet, the tricycle support ring The three ends may be detachably connected to the three rings by elastically engaging the outer ends of the supporting surface portions of the support surface to the engaging recesses of the three-wheeled frame.

According to this, the trivet can be attached to or detached from the upper plate while the trivet and the trivet are connected to the support ring, and thus the detachable operation can be facilitated.

In addition, the receiving body may be provided with a receiving member that receives the load of the trivet by placing the lower end of the lower part of the lower portion of the support ring.

According to this, since the load of the trivet can be distributed to the periphery of the furnace opening of the upper plate and the receiving member, the load of the trivet can be prevented from being concentrated on the upper plate and the deformation and damage of the upper plate can be reliably prevented.

In addition, in the present invention, when the top plate is made of metal, a standing edge may be formed along the periphery of the furnace opening to form a cylindrical shape, and the trivet may be supported by placing the support ring on the standing edge.

According to this, since the periphery of the furnace opening is reinforced by the standing periphery, the trivet can improve the mounting stability of the support ring, whereby the trivet's supporting state can be stabilized.

In addition, when the upper plate is made of glass, a metal protective ring may be attached to the periphery of the furnace opening, and the trivet may be supported by placing a trident support ring on the protective ring.

In the glass top plate, when an impact or the like is applied to the periphery of the furnace opening formed on the top plate, cracks may easily occur on the periphery of the furnace opening, and thus metal protection for preventing cracks at the periphery of the furnace opening. Fit the ring. This kind of protection ring includes, for example, a cylindrical portion inserted into the furnace opening and a flange portion formed successively at the upper and lower ends of the cylindrical portion to face the upper and lower surfaces of the upper plate, and between each flange portion and the upper plate. It is attached through the packing. By supporting the trivet by putting the tricycle support ring on such a protective ring, the tricycle as well as the tricycle can prevent contact between the support ring and the top plate, and the protective ring can improve the mounting stability of the tricycle support ring.

As shown in FIG.

As shown in FIG. 2, the gas burner 4 is formed by forming a plurality of inward flame holes 10 in the annular burner body 9 having the same center as the furnace opening 3. It consists of a type burner. The burner body 9 is fixed to a pedestal (not shown) formed on the bottom plate 11 of the furnace body 1.

On the burner body 9, an annular guide member 12 for guiding air from the outside to the flame hole 10 as secondary air for combustion is provided, and the guide member 12 is a burner body 9 The air passage 13 for the secondary air is partitioned between the upper surface and the upper surface. The guide member 12 is attached to the burner body 9 through the bracket which is not shown in several places of the circumferential direction. In addition, the inner circumferential side portion of the guide member 12 extends upward toward the furnace opening portion 3, and a flame guide for guiding the flame of the gas burner 4 into the furnace opening portion 3 by the inner circumferential side portion is provided. To be configured.

In addition, the periphery of the kiln opening 3 is a standing periphery, which is erected in a tubular shape over its entire circumference in order to prevent deformation of the periphery of the periphery and prevention of boiling soup and the like. 14) is formed. In addition, the lower part of the inner diameter part of the gas burner 4 (the space enclosed by the burner main body 9), and the soup tray 15 for receiving the boiling soup etc. which fall through this inner diameter part, etc. ) Is installed.

As shown in Fig. 1, on the front plate 2, a pair of left and right operation levers 16 for driving operation of the left and right gas burners 4 are arranged on the front side thereof, and the left and right pair of furnace openings ( Corresponding to 3), a pair of left and right trivets 17 on which a cooking vessel (not shown) is placed is arranged. Each tricycle 17 is composed of a plurality of trigeminal protrusions 18 arranged at intervals in the circumferential direction, and an annular trivet mold 19 connecting these trigeminal protrusions 18. In this embodiment, the trivet 18 and the trivet 19 are cast integrally with an iron-based material, for example, stainless steel. As shown in FIG. 2, the trivet 19 is used as a cover ring which covers and covers the periphery part (range including the standing periphery part 14) of the furnace opening part 3 from the upper side.

In addition, as shown in FIG. 2, the tricycle support ring 20 is interposed between the periphery of the furnace opening 3 and the tricycle 17. That is, the trivet support ring 20 is placed on the upper end of the standing periphery 14 formed at the periphery of the furnace opening 3, and the trivet lifts the trivet 17 from the upper plate 2 by the support ring 20. I support it in one state.

The trivet support ring 20 is formed by forming a thin plate made of metal (for example, stainless steel, etc.) in a cylindrical shape, and as shown in FIGS. 2 and 3, at the upper end of the standing edge 14 of the furnace opening 3. The mounting surface portion 21 to be placed, the lower portion 22 extending downward along the periphery of the furnace opening 3 at the inner circumference of the mounting surface portion 21, and the outer circumference of the mounting surface portion 21 to the upper side. It is a shape provided with the upstanding part 23 standing up and the support surface part 24 extended toward the outer side from the upper edge of the standing part 23. As shown in FIG. The support surface portion 24 abuts on the lower surface side of the trivet 19, and the standing portion 23 forms a gap between the trivet 17 and the upper plate 2. And, since the tricycle support ring 20 cannot be visually recognized from outside by being covered and hidden by the trivet 19 as a cover ring, the tricycle support ring 20 is installed. No deterioration in appearance is caused.

When the tricycle 17 is supported by the tricycle support ring 20, the tricycle 17 is excited from the upper plate 2, and thus, the upper plate 2 is brought into contact with the tricycle 17 by the upper plate 2. The damage on the upper surface can be prevented. In addition, since the tricycle support ring 20 is formed separately from the tricycle 17, the tricycle support ring 20 does not need to be made of the same material as the tricycle 17. When the tricycle support ring 20 is formed using a metal that is lighter than the tricycle 17, the upper plate 2 It is advantageous to reduce the load on the load. When the tricycle support ring 20 is attached to the furnace opening 3 of the upper plate 2, the mounting surface 21 is easily formed by only inserting the lower portion 22 into the furnace opening 3. Since the trike 17 is supported in a relatively large area by the support surface 24 and the support position is on the outer circumferential side than the center of the trike 17, the support state of the trike 17 is maintained. I can stabilize it.

2 and 3, a plurality of vent holes 25 are formed in the standing portion 23 of the trivet support ring 20. The vent member 25 allows the guide member 12 to smoothly supply combustion secondary air to the vent passage 13 partitioned between the upper surface of the burner body 9. In addition, as shown in FIG. 1, the air introduction part 26 can be formed in the rear end of the upper plate 2, or sufficient secondary air for combustion can be introduced in the clearance of the burner body 9 and the upper plate 2, etc. If there is, the trivet does not have to form the vent hole 25 in the standing portion 23 of the support ring 20.

In addition, as shown in FIG. 2, the protruding member 27 which protrudes toward the upper surface of the upper board 2 is attached to the lower edge of the rear end of the trigeminal protrusion 18. As shown in FIG. The protruding member 27 is formed of a metal having a lower hardness than the trivet 17 (brass in the present embodiment), and protrudes to a position with a slight distance (about 1 to 1.5 mm) from the upper surface of the upper plate 2. have. As a result, when the trivet 17 is in a normal horizontal posture, since the protruding member 27 is in a non-contact state with respect to the upper plate 2, the damage of the upper plate 2 due to contact with the protruding member 27 is prevented. Does not occur.

In addition, for example, even if a situation occurs in which the trivet 17 is tilted by cooking cooking the cooking vessel violently on the trivet 17, the trivet 17 is brought into contact with the upper plate 2. Tilting is suppressed, and the position shift of the trivet 17 with respect to the furnace opening 3 can be prevented. In addition, since the inclination of the trivet 17 at this time is very small, the tricycle 17 immediately returns to the horizontal position, and the contact time between the protruding member 27 and the upper plate 2 is also very short, and the protruding member 27 Since the tricycle 17 is lower in hardness, the risk of damage to the upper plate 2 due to the contact between the protruding member 27 and the upper plate 2 is also very small.

Although not shown, a rubber cap or the like may be attached to the protruding member 27, thereby reliably preventing damage to the upper plate 2 due to the contact between the protruding member 27 and the upper plate 2. can do. In addition, although not shown, the protrusions 27 do not have to be formed when the trivets are not shaped to extend outwardly of the trivets 19.

In addition, even if the trivets placed on the upper end of the standing periphery 14 formed on the periphery of the furnace opening 3 are provided with packings formed by rubber or the like, although not shown, do. Thereby, the damage of the upper end of the standing peripheral part 14 of the upper board 2 can also be prevented.

Also in this case, similarly to the first embodiment described above, the trivet 17 is in an excited state on the upper plate 28, thus preventing damage to the upper surface of the upper plate 28 due to the contact between the trivet 17 and the upper plate 28. In addition, the trivet 17 can be stably supported. In addition, a packing formed by rubber or the like may be provided on the lower surface of the mounting surface portion 21 of the tricycle placed on the upper flange portion 31 of the protection ring 29 by rubber or the like. It is possible to prevent damage to the upper surface of the upper flange portion 31 of the protective ring 29.

In addition, as shown in Fig. 5, the trivet further extends the lower part 22 of the support ring 20 to the lower side, and a receiving member supporting the lower part 22 on the bottom plate 11 of the main body 1 ( 38) may be provided. At this time, the triangular contact with the lower end of the lower portion 22 of the support ring 20 to the receiving portion 39 formed horizontally on the upper end of the receiving member 38. According to this, since the load of the trivet 17 can be disperse | distributed by the receiving member 38 so that it may not concentrate on the periphery of the furnace opening part 3, especially in the glass top board 28, the periphery of the furnace opening part 3 is made. Can prevent cracking. In addition, although not shown in the above-described first embodiment, the receiving member 38 is provided to disperse the load of the trivet 17 so that deformation in the peripheral portion of the furnace opening 3 of the aluminum upper plate 2 is assured.
