Patent Document 1: Japanese Patent Application Laid-Open No. 2001-4155

The present invention relates to a trivet installed on a top plate of a stove to support cooking utensils such as a pot on a burner.

In general, the gas stove is provided with a trivet for supporting cooking utensils such as a pot on the burner. The trivet is provided with a frame placed on the top plate of the gas stove, and a plurality of protrusions provided on the frame so as to sequentially project toward the upper portion of the burner.

As this type of trivet, it is known to connect a plurality of protrusion members integrally by welding or caulking to a frame formed in an annular shape by a metal plate or a metal shell. However, according to this, there is a problem that the manufacturing cost becomes expensive because the work of connecting the plurality of protrusion members to the mold is cumbersome and the work efficiency is low.

Thus, the trivet disclosed in Patent Document 1 described above is known as being capable of manufacturing at low cost by facilitating manufacture by omitting the operation of connecting the protrusion member to the mold and reducing the number of parts. The trivet disclosed in the patent document 1 blanks a band-shaped mold and a plurality of protrusions that project continuously along the mold from a metal sheet, and joins both ends of the mold by welding or the like, and then molds each protrusion. It is formed by bending toward the center of (hereinafter also referred to as "bending").

Said trivet 31 is the junction part 35 and this junction part which are formed so that each protrusion 33 may stand in succession to the upper end of the frame 32, as shown to (a) and (b) of FIG. It consists of the extension part 36 formed in the side end 35a of 35. As shown in FIG. The trivet 31 blanks one sheet of metal plate, joins both ends 32a and 32b of the mold 32, and extends at the side end 35a of the joint 35 of the protrusion 33. Since 36) can be formed simply by bending it in the center direction, it is easy to manufacture and can be manufactured at low cost.

However, in the trivet 31 disclosed in Patent Literature 1, the junction 35 is erected so that combustion exhaust flowing toward the outside of the burner is encountered, so that the smooth flow of the exhaust is prevented by the junction 35, resulting in poor combustion. It may cause. In addition, in the case of the trivet 31 disclosed in Patent Literature 1, as shown in Fig. 7A, the area of the junction 35 is relatively small, but the trivet may be placed with a heavy cooking utensil. Therefore, there is a possibility that the weight cannot be supported by the same size as the connection part 35. Therefore, in order to be able to support a certain amount of weight, it is actually necessary to increase the area of the connection part 35, but the problem that the combustion state of the burner is further worsened when the area of the connection part 35 is increased. have. In the manufacture of the trivet 31, it is necessary to perform welding, caulking or the like when joining both ends 32a and 32b of the mold 32.

In order to solve the above problems, the present invention, in order to solve the above-mentioned problems in more detail, blanking only one sheet of metal plate without requiring caulking or welding and bending it to a predetermined shape It is also an object of the present invention to provide a trivet that can be formed and that does not disturb the combustion exhaust of the burner.

The trivet for the stove according to the present invention for achieving the above object is "a trivet having a mold placed on the top plate of the stove, and a plurality of protrusions which project from the mold to the upper side of the burner in succession to support the cooking utensils. In the frame and the projection is formed integrally by blanking the metal plate material, the protrusion is a bottom plate portion protruding outward from the outer periphery of the frame in the state of blanking the metal plate material, and the bottom plate A standing portion formed at one side end of the portion, and a protrusion projecting outwardly from the standing portion, wherein the frame is formed in an annular shape to surround the burner, and is formed at an outer side in an inner circumference along a line extending radially from the center thereof. Having a groove formed toward the surface, and the standing portion is bent from the side end of the bottom plate portion to the back surface side of the frame, Is bent folded back so as to overlap the rear surface of the frame at the outer periphery of the bottom part the frame, the rising portion is inserted into the groove characterized in that the protruding on the surface of the mold. "

In the furnace trivet of the present invention, the standing portion of the protrusion protrudes from the groove to the surface of the mold, and the groove is formed along a line extending radially outward from the center of the mold. Therefore, since there is no obstacle such as a junction where the combustion exhaust of the burner collides like a conventional trivet, smooth flow of the combustion exhaust can be achieved and good combustion of the burner can be ensured. Moreover, since the said frame and the protrusion are integrally formed by blanking a metal plate material, and this protrusion can be formed only by bending to a predetermined shape, it can manufacture easily and can manufacture at low cost. Moreover, since the said frame is formed in annular shape, it does not need to carry out welding, caulking process, etc. like a conventional trivet.

Moreover, in the furnace trivet of this invention, it is preferable that the outer periphery of the said frame is bent downward with the said bottom plate part, and the inner periphery of the said frame is bent downward and bent. As described above, since the cross section of the frame is formed in a 'c' shape by bending the outer and inner circumferences of the mold downward, the strength and durability of the mold can be improved.

Moreover, in the furnace trivet of this invention, it is preferable that the boundary part of the said groove | channel and the said standing part is covered with the filler. According to this. Since boiling broth etc. do not intrude into the said boundary part, daily management becomes easy. As this filler, enamel processing and heat-resistant coating etc. are preferable, You may give an enamel processing and heat-resistant coating to the whole trivet not only the said boundary part.
