I: Prior art 3 Conventional technology In the past, according to Japanese Patent Laid-Open Publication No. Sho 58-100232, a fire rack for a stove is known, which is located below the upper edge of the fire rack claw and is located at 10 fires. A wide annular partition plate is provided in a radial direction above the lower end of the leg portion of the frame claw, and a plurality of fire frame claws are inserted and fixed to the partition plate at the leg portion. The fire stand has the advantage of separating the flow of the combustion exhaust gas from the burner and the flow of one of nine ': k cm-personal air up and down by the partition plate and improving the combustibility of the burner. 15 In addition, the aforementioned fire rack is used by a user in a normal stove which has a burner facing an inner periphery of a soup receiving pan formed by mounting the burner on an opening formed on a top plate made of a metal plate. Recently, a top plate made of glass and The burner faces the open top glass stove which is opened / formed on the top plate. Glass top stoves are popular because they are flat, attractive and easy to clean. 20 The problem to be solved by the invention is described. The fire shelf is large and the weight is increased. At the same time, the overflowing soup or conditioner is easy to fall and adhere to the partition, and because the partition is high temperature, it overflows. The broth or sauce is burnt on the divider and cleaning is troublesome. In addition, the right-hand side of the conventional fire rack is used in a normal stove, and the outlet of the secondary air passage is located on the soup receiving tray through the partition plate area 1233975 玖. This part is close to the burner and becomes a very high temperature due to radiant heat. It is a part that is easily burnt due to the spilled soup or conditioning substances, and it is located in the outlet part of the secondary air path. Therefore, just before the burner 5, the flow of the secondary air will be disturbed and the supply of the secondary air to the burner will be uneven, which will have a bad effect on the flammability. In addition, some people have considered the use of conventional fire racks in glass top stoves. However, the fire stands are bulky due to the presence of partition plates, and will damage the delicate appearance of glass top stoves and make the appearance poor. . 10 In view of this, the object of the present invention is to provide a small and light fire stove for stoves, which can improve the maintainability and appearance without impairing the flammability improvement effect of the burner, and a glass top surface using the fire stand. Stove. [Akihito] Means for solving the problem 15 & The above-mentioned problem is solved, in a fire rack for a stove having a plurality of fire rack claws arranged at intervals in the circumferential direction, according to the present invention, below the upper edge of the fire rack claw and A ring frame formed by a strip-shaped plate extending up and down in the width direction is provided above the lower end of the legs of the fire frame claws, and the plurality of fire frame claws are fixed to the ring at the feet of each fire frame claw Shape box. 20 X, in a glass top stove with 2 ports formed by a glass top plate and a burner facing the top plate, according to the present invention, a fire stand describing the present invention is placed on the top plate to surround the burner . Since the ring frame of the fire frame of the present invention has the width in the up-down direction, even if there is no partition plate that expands radially as in the past, the flow and direction of combustion exhaust gas from the combustion 1233975 玖, the invention explainer, The flow of the secondary air of the burner is divided up and down. In particular, if it is a glass top stove, the top plate does not have the depression of the soup receiving plate and is flat until the burner part, so the secondary air flowing in from the space below the ring frame flows smoothly along the top plate. Up to 5 knives to the burner section, even if a fire stand with a partition plate as in the past is not used, the flammability of the combustion benefit can be improved. In addition, because the light radiation heat from the burner flame penetrates the glass top plate to keep the top plate at a relatively low temperature, it can suppress the scorched deposits on the top plate and prevent secondary air caused by these accumulations. Disturbance of ML motion has adverse effects on flammability. 10 Moreover, the ring frame is only a width of the plate thickness of the band-shaped plate from the up and down direction and has a ring shape, so the overflowing soup or conditioner is not easy to adhere, and it extends radially inward from the burner in the past. The partition plates are different and are not easy to be heated. As a result, the overflowing soup or the conditioner can be effectively prevented from burning, and the fire rack can be easily cleaned. Moreover, it is lighter than the conventional fire stand 15 using a partition plate, and at the same time, the fire stand is light and does not damage the appearance even when used in a glass top stove.

In the figure, 1 is a glass top plate 20 ', and the burner 3 faces the opening 2 formed in the top plate i. The burner 3 is composed of a metal plate burner body 4 having a mixing tube portion 4a and a ring-shaped burner head 4b, and a ring-shaped burner cover 5 placed on the burner head. The head 4b is inserted into the protective ring 6 attached to the periphery 2 of the opening 2 of the top plate 1 and protrudes from the top plate 1. Next 1233975 发明, invention description ’By burning! The tooth shape of the outer peripheral portion of the lower surface of the 1 cover 5 forms a plurality of flame holes 5a, and an outward flame is formed by the gas ejected from the burner head 4b through the flame holes 5a. In addition, a small flame hole% is formed in the burner cover 5 upward, and an umbrella portion 5c covering the internal portion of the burner cover 5 from above to prevent the overflow of the soup 5 from falling is integrally formed. A fire stand 7 is placed on the top plate 1 to surround the burner 3. As shown in Fig. 2, the fire stand 7 has a plurality of fire stand claws 8 (six in the example of the figure) arranged at intervals in the circumferential direction. Each fire claw 8 is formed with an outer leg portion 8a, a support claw portion 10 for a conditioner p extending from the upper end of the leg portion 8a inward, and a pair of top plates t extending inward from the lower end of the leg portion 8a. The support portion 8c has a roughly [] shape. The fire stand 7 further has a ring-shaped frame 9 formed by a strip-shaped plate extending up and down in the width direction. The ring frame 9 is arranged below the upper edge of the fire claw 8 (the upper edge of the supporting claw portion 8b) and above the lower end of the chattering portion 8a (the lower edge of the support portion 8c). Each fire stand claw 8 is fixed to the ring frame 9. Further, in this embodiment, a notch portion 8d is formed on the outer edge of the leg portion 8a, and the leg portion 8a is welded and fixed to the ring frame 9 while the ring frame 9 is fitted into the notch portion 8d. When the conditioner P is placed on the fire stand 7 and the burner 3 is on fire, the combustion exhaust gas from the burner 3 flows outward along the bottom of the conditioner p, as shown by the ring frame 9 in FIG. The space between the upper edge and the bottom surface of the conditioner p is discharged to the outside. In the burner 3, the secondary air is supplied from the inside through the burner head 4b and the inner diameter portion of the burner cover 5 as shown by the arrow b. At the same time, it passes between the lower edge of the ring frame 9 and the top plate 1. The secondary air is also supplied from the outside as shown by arrow c. 1233975 发明, description of the invention, here, the width of the gap between the upper edge of the annular frame 9 and the bottom surface of the conditioner P, that is, the distance between the upper edge of the annular frame 9 and the upper edge of the fire frame claws γ When the combustion exhaust gas is set to a value sufficient for exhausting the combustion exhaust gas, the combustion exhaust gas is smoothly branched from the space between the upper edge of the annular frame 9 and the bottom surface of the conditioner p without branching under the% -shaped frame 9. Secondly, since the annular frame 9 has a width in the up-down direction, the secondary air flows in through the space between the lower edge of the annular frame 9 and the top plate 1 due to the flow of combustion exhaust gas. Secondly, since the top plate 1 does not have the concave portion of the usual cooking appliance receiving tray for soup and is flat until the burner part, the secondary air flowing through the space between the lower edge 10 of the ring frame 9 and the top plate 1 It flows to the burner part smoothly against the top i, and the flammability of the burner 3 is improved. In addition, the top plate i is made of glass, and the radiant heat from the burner flame passes through the top plate 丨, so that the top plate 1 can be maintained at a relatively low temperature, so that the scorched deposits on the top plate 丨 can be suppressed 'and can also be prevented from being caused by these accumulations. Disturbance of secondary air flow and 15 adverse effects on flammability. In addition, the ring frame 9 is a ring-shaped plate having a width of only a portion of the thickness of the band-shaped plate when viewed from the up and down direction, so that the spilled soup or the conditioner is not easy to adhere 'and extends radially inward from the conventional burner. The partition plates are different and are not easy to be heated. As a result, it is possible to effectively prevent the burning of the soup or the conditioner from burning, and the cleaning of the fire rack 7 is easy. Furthermore, it is lighter than a conventional fire stand using a partition plate, and at the same time, the fire stand 7 is light and does not deteriorate the appearance even when used in a glass top stove. In addition, in order to improve the separation performance between the flow of combustion exhaust gas and the flow of secondary air, the upper and lower width L2 of the annular frame 9 is set to the annular frame 9 1233975 玖, the upper edge of the invention and the fire claw 8 The distance L1 between the upper edges is 0.4 to 5 times as ideal. In addition, the distance L3 between the lower edge of the annular frame 9 and the lower end of the leg portion 8a varies according to the necessary supply amount of secondary air from the outside. However, if 1 is supplied twice from the inside as in this embodiment For air, it is better to set it to 0.3 times L 丨 5 or more. The above description is that the burner 3 is a glass top stove using an outer flame burner forming an outward flame, but the same applies to a glass top stove using an inner flame burner forming an inward flame. this invention. Example 0 In a glass top stove shown in Fig. 1, a fire stand having a ring frame 9 (an embodiment of the present invention) and a fire stand without a ring frame (comparative product) were used for a fire test.
