Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a flame-retardant appliance for preventing overheating of a tempura frying pan, mainly to prevent tempura oil from being overheated in a tempura frying pan placed on the trivet of a gas stove. used to prevent

(Conventional technology) Most tempura pans made using metal materials such as iron and copper are conventionally placed directly on the trivet of a gas stove, and the gas flame burns the bottom and side walls of the tempura pan. had been heated.

(Problem that the invention aims to solve) When heating the bottom wall or side wall of a tempura pan directly with a gas flame, as in the past, the tempura oil such as salad oil inside the frying pan is heated through the bottom wall or side wall. The amount of heat transferred is larger than the amount of heat dissipated through the surface of the tempura oil or the side wall of the tempura pan that is not heated by the gas flame, and the tempura oil reaches a temperature suitable for frying tempura in a relatively short time. For example, it is heated to around 180°C, and thereafter the temperature continues to rise, albeit at a slower rate.

For this reason, if the person frying tempura is away from the tempura pot for some time, for example by using the telephone or other means, the tempura oil will be heated from the flash point to the ignition point, above the temperature suitable for frying tempura. One of the main causes of spontaneous combustion and fires
I was getting older.

(Means for solving the problem) This invention was made to solve the above problem, and the cylindrical holding member placed on the trivet engages with the trivet of the gas stove at its lower edge. A notch is formed, and a required number of notches for exhausting combustion gas are provided on the upper edge, and a disc-shaped flameproofing member protrudes outward from the holding member at the upper end of the cylindrical holding member. The flameproofing member is integrally provided, and has a cylindrical rising portion in the center that supports the bottom wall of the frying pan, thereby configuring a flameproofing device for preventing overheating of the frying pan.

(Function) When a tempura pan is heated using a flame-retardant device fixed on the trivet of a gas stove, the gas flame that comes out from the combustion gas exhaust notch in the holding member,
The disk-shaped flameproof member provided so as to protrude outward from the upper end of the holding member reliably prevents heating of the side wall of the frying pan. Therefore, the oil inside the frying pan is heated through the bottom wall of the frying pan that emerges from the opening of the cylindrical rising part, and the side wall of the frying pan located above the opening is directly heated by the gas flame. It is hardly heated and functions as a heat dissipation area for heated tempura oil.

Therefore, the amount of heat transferred to the tempura oil from the regulated bottom wall of the tempura pan, and the amount of heat radiated from the surface of the heated tempura oil and the side wall of the tempura pan above the opening of the rising part. , it becomes easier to balance the frying oil before it reaches the flash point or ignition point, and even if the frying pan is heated for a long time, the frying oil will not rise above a certain temperature at which it has reached equilibrium.

Moreover, the combustion gas rising inside the cylindrical holding member is discharged from the notch provided on the upper edge of the holding member that joins the flameproofing member, so the gas flame maintains complete combustion while cooking the tempura. Heat the bottom wall of the pan.

(Example) Figures 1 and 2 show an example of this invention, in which a flameproof member 1 formed in a disc shape is
A cylindrical rising part 2 supporting the bottom wall of the tempura pan A is integrally provided in the center thereof. For example, six rectangular notches 3 are formed at equal intervals on the upper edge of the cylindrical rising portion 2. The shape, number, and arrangement of the notches 3 are not limited to those in the above embodiment, and the notches 3 may be omitted when the height of the rising portion 2 is relatively small.

Reference numeral 4 denotes a cylindrical holding member attached to the lower surface of the flameproofing member 1 by welding or other means. In order to discharge the combustion gas trapped in the member 4, for example, four notches 5 of a rectangular or other shape that are relatively long in the circumferential direction are provided at equal intervals, and at the lower end of the holding member 4. A notch 6 is provided on the rim to engage with the trivet B of various gas stoves used. Therefore, the number of notches 6 is the trivet B of the gas stove you are using.
When the number of arms is 3, 4, 5, 6, or 8, the number of arms will be 3, 4, 5, 6, or 8 accordingly.

It is desirable that the flameproofing device consisting of the disc-shaped flameproofing member 1 and the cylindrical holding member 4 be made by enameling both sides of an iron plate, but it is of course possible to use other metal materials. .

Since this embodiment is constructed as described above, after each notch 6 provided on the lower edge of the holding member 4 is engaged with the trivet B of the gas stove,
When the tempura pan A is placed on the circular opening of the rising part 2 and heated, the tempura oil C is heated by the gas flame that reaches the bottom wall of the tempura pan A through the holding member 4 and the rising part 2 of the flameproof member 1. , mainly heated.

In addition, even if the gas flame comes out together with the combustion gas from the notch 5 for discharging combustion gas provided in the holding member 4, it is possible to move the same length outward from the outer circumference of the upper end of the holding member 4. The disc-shaped flameproofing member 1 provided so as to protrude from the flameproofing member 1 reliably prevents the gas flame from circulating above the flameproofing member 1 and directly heating the side wall of the frying pan A. The tempura oil C radiates heat not only through its surface but also through the side wall of the tempura pan A.

Therefore, if you use flame-retardant equipment, tempura pan A
Not only is the heating area of the bottom wall of tempura pan A regulated to be slightly smaller, but also the heat dissipation from the side wall of tempura pan A is effective, so even when tempura oil C is heated for a long time, By balancing the temperature between the temperature suitable for frying tempura (for example, 180°C) and the flash point or ignition point, it is possible to prevent problems such as fire from occurring.

Figure 3 shows the test results showing the effect of this example, where a shows the case where the tempura pan was heated without using a flameproof appliance, and b shows the case where the tempura pan was heated with the flameproof appliance. . Outer diameter of flameproof member 1 20
cm, the inner diameter of the rising part 2 is 15.5 cm, 600 c.c. of salad oil is put in the tempura pot A, and the relationship between the temperature measured with a thermocouple at a point approximately 10 mm below the oil surface in the center of the tempura pot A and the heating time is shown. It is something that

In addition, when heating the tempura pan A using a flameproof appliance, the combustion gas rising inside the cylindrical holding member 4 flows through the notch 5 provided on the upper edge of the holding member 4 and the rising portion 2. Since the gas flame is discharged to the outside of the flameproof appliance from the notch 3 provided on the upper edge, the gas flame can heat the bottom wall of the deep fryer A for a long time while maintaining complete combustion. Furthermore, these notches 5 and 3 can be used to know the combustion state of gas inside the flameproof appliance from the outside, and are therefore useful for maintaining safety during use.

FIG. 4 shows a second embodiment of this invention, in which the disk-shaped peripheral portion 1a of the flameproof member 1 in the previous embodiment is formed so as to be bent slightly diagonally upward.

When such a bend is formed in the periphery of the flameproof member 1, the strength of the flameproof member 1 is strengthened, the combustion gas is discharged from the notch 5 more smoothly, and the combustion of gas through the notch 5 is The status can be made easier to see.

5 and 6 show a third embodiment of this invention, in which the lower edge of the holding member 4 in the first embodiment is engaged with various numbers of trivets B used in gas stoves. Multiple sets of notches 6A _i (i=3,
4, 5, 6, ...) are provided in common with a notch 6A _p serving as one reference, and an indicator 7 indicating that it is a reference is provided on the holding member 4 above the notch 6A _p serving as a reference. This is the case when it is set. A mark or an aperture can be used as the indicator 7.
In Fig. 5, ,,, and are the positions where the central angle is divided into 3, 4, 5, and 6 equal parts, respectively, and the notches 6A when the number of trivets B is 3, 4, 5, and 6. ₃ , 6A ₄ , 6A ₅ , and 6
Shows the location where A ₆ is installed.

When the flameproofing device is formed in this way, by engaging the notch 6A _p with the index 7 with one arm of the trivet B, the other notch 6A _i (i = 3, 4, 5, 6, ...) can be automatically engaged with each other arm of the trivet B, resulting in an excellent practical effect.

(Effects of the invention) According to the structure of this invention, the following excellent effects are achieved.

(1) Since a disc-shaped flameproofing member is provided at the upper end of the holding member that protrudes outward by the same length from the outer circumferential surface of the holding member, the gas flame passes through each notch of the holding member to the outside together with the combustion gas. Even if it comes out,
By the action of the disc-shaped flameproofing member, the side wall of the deep fryer pan above the rising portion of the flameproofing member can be reliably prevented from being heated by the gas flame or combustion gas.

In addition, due to the flameproof member and its rising part,
Since the heating area of the tempura pan is regulated to be slightly smaller, the side wall of the tempura pan above the rising portion can be used as a heat dissipation area for the heated tempura oil.

For this reason, even if the tempura pan is heated for a long time, the temperature of the tempura oil will be prevented from rising above a certain temperature below the ignition point, effectively preventing fires caused by tempura oil. It can be prevented.

(2) Since the required number of notches are provided at the joint between the cylindrical holding member and the flameproofing member, it can be used to heat a tempura pan for a long time by completely burning the gas within the holding member. .

(3) If the lower edge of the cylindrical holding member is provided with a notch that engages with the trivet of the gas stove, the tempura pan can be held in a stable state with the flame-retardant appliance locked to the trivet of the gas stove. It can prevent overheating and prevent the occurrence of fire caused by overheating.
