Description

The present invention relates to a solid fuel set for chafing, a solid fuel container for chafing, and a method for keeping the chafing warm.

Recently, a meal system called “Viking” or “Buffet”, which can eat as much as you like from a specified range, has gained popularity. In such a meal system, it is necessary to keep a large number of cooked dishes such as cooked dishes at a predetermined temperature for a certain period of time, and for this purpose, a dish warmer called “chafing” is often used.

Chaefing is a device configured to place a heat source under a dish or plate on which food is placed, and to keep the food warm by hot water or direct fire, but it is difficult to control the temperature with direct fire. For this reason, water (hot water) is often placed under the plate or plate, and the dish is often kept warm. When such chafing is used, conventionally, liquid fuel is put in a liquid fuel container having a combustion core, and the dish is kept at a predetermined temperature by burning the combustion core and boiling water.

In Patent Document 1, as a liquid fuel combustion container used for such chafing, a transparent empty space is formed in which an opening is provided at one end and the other end is closed to accommodate a liquid fuel. Or a container made of a translucent material, a lid that is substantially the same shape as the opening of the container, has a through hole at a substantially central portion thereof, is detachably attached to the opening, and closes, and the penetration of the lid There is disclosed a combustion container for liquid fuel, characterized in that it comprises a combustion core that is inserted through a hole and has an upper end projecting from the outer surface of the lid.

When using such a liquid fuel combustion container, the liquid fuel is transferred from a large container that contains liquid fuel to the liquid fuel combustor, and then the combustion core is ignited to generate a flame. And heat the chafing.

However, when such a liquid fuel is used, there are the following problems. In other words, it is necessary to put a certain amount of liquid fuel in the liquid fuel combustion container. In that case, it is necessary to open the lid and replenish the fuel. Replacement is required.
In addition, liquid fuel is likely to spill when transferred to a liquid fuel combustion container, and liquid fuel is likely to spill when carrying a container containing liquid fuel. However, if liquid fuel is spilled, there is a risk of fire. There is a big problem that there is. In addition, there is a large amount of smoke and soot generated from the flame, and there is a problem that a large amount of smoke is generated particularly during fire extinguishing. Furthermore, there is a problem that it is difficult to ignite when the combustion core is ignited.

The present invention was made in order to solve the problems of the conventional liquid fuel described above, and it is not necessary to replace the combustion wick, and there is no risk of fuel spilling. In addition, a solid fuel set for chafing that is optimal for providing a heat retaining method for chafing that has good ignitability, generates less smoke and soot, and can control the combustion time, and a chain used in the solid fuel set for chafing It is an object of the present invention to provide a solid fuel container for finging and a method for keeping warming of the couching using the solid fuel set for couching.

That is, the solid fuel set for chafing of the present invention is
A lid having an opening at the center, and a solid fuel container for chafing comprising a container body that is open at the top and contains solid fuel inside,
A solid fuel set for chafing comprising solid fuel,
The container body and the solid fuel have a quadrangular prism shape or a cylindrical shape in which a cross-sectional shape parallel to the bottom surface is a rectangle or a circle,
The length of the rectangular diagonal line in the cross section of the container body or the diameter of the circle is Rmm, the height of the container body is Zmm,
The rectangular diagonal length or the circular diameter of the solid fuel in the cross section is dmm, the height of the solid fuel is hmm,
When the diameter of the opening of the lid is rmm,
The following formulas (1) to (4) are satisfied.
40 mm <R <120 mm (1)
0.2 <r / R <0.8 (2)
0.20 <Z / d <0.60 (3)
0.75 <h / Z (4)
In the following, the rectangular diagonal length or the circular diameter R in the cross section of the container main body is also simply referred to as “the length or diameter R of the container main body”, and the above cross section of the solid fuel in the cross section. The length of the diagonal line of the rectangle or the diameter d of the circle is also simply referred to as “the length or diameter d of the solid fuel”.
In each of the following embodiments, the solid fuel set for chafing is also simply referred to as a solid fuel set, and the solid fuel container for chafing is also simply referred to as a solid fuel container.

In the solid fuel set for chafing of the present invention, since the solid fuel is used, it is only necessary to put the solid fuel in a container and ignite with a lighter or the like before starting the heat insulation of cooking or the like. Moreover, since there is no need to replace the combustion core and there is no risk of fuel spilling, preparation before use is extremely simple. In addition, when liquid fuel is used, if liquid fuel is spilled, the spilled liquid fuel may catch fire and there is a risk of fire, but in the case of solid fuel, there is a risk of such fire. There is no.

Further, when the upper surface of the solid fuel is located below the opening of the lid, it is difficult to ignite a little even if a lighter or the like is used. However, in the solid fuel set for chafing of the present invention, the expression (4) is satisfied, Since the height h of the solid fuel exceeds 75% of the height Z of the container body and is close to the opening of the lid, it can be easily ignited using a lighter or the like.

Further, the ratio of the diameter r of the opening to the length or diameter R of the container body (the length or diameter R of the lid) is 0.2 <r / R <0.8 as shown in the equation (2). Since it is set, the solid fuel burns well, and the generation of smoke and soot is less than that of the liquid fuel, so that an atmosphere such as viking can be kept good.

Further, the length or diameter R of the container body is set to 40 mm <R <120 mm as shown in the formula (1), and the diameter of the opening with respect to the length or diameter R of the container body (length or diameter R of the lid). As shown in equation (2), the ratio of r is 0.2 <r / R <0.8, so that solid fuel can be burned well and the combustion time can be controlled. become.

Furthermore, the ratio (Z / d) of the height Z of the container body to the length or diameter d of the solid fuel is 0.20 <Z / d <0.60, and the height h of the solid fuel is the height of the container body. Since the height exceeds 75% of Z, the amount of burning residue can be minimized and solid fuel can be burned well.

Regarding the invention according to claim 1 and its effects, a part of the configuration of the solid fuel set for chaefing according to the present invention is described in association with the effects as described above. All of the constituent requirements described above have an effect on the individual effects described above, and by setting these constituent requirements as a whole, the various effects described above can be achieved, and none of these constituent requirements are lacking. However, it is difficult to exert the above effects.

In the solid fuel set for chafing of the present invention, it is further desirable to satisfy the following expression (5).
(R−r) / 2 <d (5)
In the above equation (5), (R−r) / 2 substantially corresponds to the width of the edge portion of the lid. When the width {(R−r) / 2} of the edge portion of the lid is larger than the length or the diameter d of the solid fuel, or in the same case, when moving in the solid fuel container body It is difficult to ignite with a lighter or the like, and burn residue tends to increase. Therefore, as shown in the equation (5), it is desirable that the diameter of the solid fuel is larger than the width {(R−r) / 2} of the edge portion of the lid.

In the solid fuel set for chaefing of the present invention, it is desirable that the length or diameter R of the container body further satisfies the following formula (6), and r / R further satisfies the following formula (7). .
50 mm <R <100 mm (6)
0.40 <r / R <0.55 (7)
By changing the length or diameter R of the container body in the above range, and further changing the size of the opening in the above range, the flame can be maintained in a more stable state, and the duration of the flame can be increased. This is because it is easier to control.

In the solid fuel set for chaining according to the present invention, the lid and the container body are preferably made of metal or ceramic.
This is because there is no fear of the lid or the container body burning, and the heating can be performed safely for a long time.

In the solid fuel set for chafing according to the present invention, the solid fuel is preferably a solid fuel mainly composed of a combustible liquid such as alcohol.
This is because it can be ignited more easily with a lighter or the like, and stable long-time heating can be easily performed.

In the solid fuel set for chafing of the present invention, it is desirable that the bottom and side surfaces of the solid fuel are covered with a coating material such as aluminum foil.
Since the flame is not generated from the side surface but generated from the upper surface, the flame has a more stable shape and can be kept warm by more stable heat.

In the solid fuel set for chaining according to the present invention, the container body preferably includes a height adjustment base for adjusting the distance between the chaining and the flame.
Since the shape of the solid fuel container is determined by the above formulas (1) to (4), it is difficult to greatly change the height of the solid fuel container. There is a possibility that the height of the solid fuel mounting portion for mounting the chafing solid fuel container may vary depending on the use and size of the chafing. However, even when the height of the solid fuel mounting portion is high, the heating state of the chafing by the flame can be made appropriate if the height adjusting table is provided in the container body.

In addition to the above-described solid fuel set for chafing, the present invention is to keep the chafing warm by using the solid fuel container for chafing used for the solid fuel set for chafing and the solid fuel set for chafing Also provided is a method for keeping warm the chafing.

It is sectional drawing shown. FIG. 2 (a) is a perspective view schematically showing an example of a method of keeping warming the chafing using the solid fuel set for chafing according to the first embodiment, and FIG. It is a partial exploded perspective view showing an example typically. FIG. 3 is a conceptual diagram schematically showing a solid fuel set for chafing according to the second embodiment.

Hereinafter, the solid fuel set for chafing of the present invention and the method for keeping warming chafing using the same will be described with reference to specific embodiments, but the present invention is not limited to these embodiments. .

The chafing, which is a heat retaining object of the solid fuel set for chafing of the present invention, is a device configured to place a heat source under a dish or plate on which food is placed and to keep the food warm by hot water or direct fire. If it is, it will not specifically limit, However, In the following embodiment, what provided the hot water tank which can fill hot water inside, and the plate fitted in the said hot water tank is demonstrated as a chafing.

(First embodiment)
FIG. 1A is a perspective view schematically showing an example of a solid fuel set used in the present embodiment, and FIG. 1B is a cross-sectional view schematically showing the solid fuel set.
In the present embodiment, the case where the container main body and the solid fuel have a cylindrical shape will be described, but the shape of the container main body and the solid fuel of the present invention is not limited to this embodiment.

A solid fuel set 10 shown in FIG. 1A has a lid body 12 having an opening 12a at the center, and a bottomed cylindrical container body 11 having an opening at the top and containing a solid fuel 13 for chafing inside. A solid fuel container 15 for chafing and a solid fuel 13 for chafing.

Here, the diameter of the opening 12a of the lid 12 is rmm, the height of the container body 11 is Zmm, the diameter of the container body 11 is Rmm, the height of the solid fuel 13 is hmm, and the diameter of the solid fuel 13 is dmm. Let the weight of the fuel 13 be Xg.

The lid 12 has a circular opening 12a at the center, and the size of the opening 12a (diameter r) is controlled to control the size of the flame and the combustion time of the solid fuel 13. Can do.

The container body 11 has a bottomed cylindrical shape having an opening at the top and a space for accommodating the solid fuel 13 therein, and the solid fuel 13 sealed with a resin film is accommodated therein.
The solid fuel 13 is mainly composed of a combustible liquid such as alcohol, and the combustible liquid is made solid by adding a small amount of a soap component or the like.
It is preferable that the solid fuel 13 is sealed with a resin film. This is to prevent the combustible components in the solid fuel 13 from disappearing due to volatilization of combustible components such as alcohol therein. However, the solid fuel does not necessarily need to be sealed with a film such as a resin film, and there is a solid fuel that does not particularly require coating. The density of the solid fuel is 0.75 to 0.85.

The container body 11 and the lid body 12 (solid fuel container 15) are made of metal or ceramic, but are preferably made of metal. It is because it is excellent in durability and can be made lightweight. Although the shape of the lid 12 is not particularly limited, it is desirable that a hanging portion that covers the upper portion of the container body 11 is formed on the outer edge as shown in FIG. This is to prevent the lid 12 from shifting. Examples of the material of the container body 11 and the lid body 12 (solid fuel container 15) include SUS430, SUS304, SUS316, aluminum alloy, tin plate, and the like.

It is desirable that the container main body 11 is provided with a height adjusting base for adjusting the distance between the chafing and the flame at the lower part thereof. When the amount of solid fuel 13 to be accommodated or the height of the solid fuel mounting part of the chafing is high, the flame may not reach the chafing. This is because the distance from the fing can be made appropriate. Instead of providing the height adjusting base on the container main body 11, the height of the flame may be adjusted by placing a base having an appropriate height and placing the container main body 11 thereon.

The solid fuel 13 is preferably about 40 to 250 g. When the diameter r of the opening 12a of the lid 12 is adjusted, the above-described amount of the solid fuel 13 is burned, so that the temperature can be kept for about 2 to 4 hours. That is, by adjusting the diameter r of the opening 12a of the lid 12, the combustion time per unit weight of the solid fuel 13 can be controlled, and the heat retention time can be controlled. In the present invention, formulas (1) to (4) are set. By changing the solid fuel capacity within this range, the weight of the solid fuel can be changed and the heat retention time is controlled. Can do.

The diameter R of the container body 11 is preferably 40 mm <R <120 mm as shown in the equation (1), and the ratio of the diameter r of the opening 12a of the lid 12 to the diameter R of the container body 11 (r / R ) Is preferably 0.2 <r / R <0.8 as shown in the formula (2).
This is because the solid fuel 13 can be burned well and the combustion time can be controlled.

When the diameter R of the container body 11 is 40 mm or less, when the solid fuel 13 having a constant weight is to be put, the height Z of the container body 11 must be increased, and the remaining solid fuel 13 is reduced. In addition, since the distance from the opening 12a of the lid 12 is increased, oxygen tends to be insufficient, and it is difficult to burn to the end. On the other hand, when the diameter R of the container main body 11 is 120 mm or more, the shape of the container main body 11 becomes too flat, and it becomes difficult to burn the solid fuel 13 to the end.

When r / R is 0.2 or less, the diameter r of the opening 12a becomes too small, so that it is difficult to form a flame. On the other hand, when r / R is 0.8 or more, a sufficient flame is formed. However, since the solid fuel 13 is consumed at the same speed as when the lid 12 is not provided, it is difficult to control the combustion time.

The diameter R of the container body 11 is more preferably 50 mm <R <100 mm as shown in the equation (6), and r / R is 0.40 <r / R as shown in the equation (7). More preferably, it is <0.55.
This is because the flame can be maintained in a more stable state and the duration of the flame can be controlled more easily.

The height h of the solid fuel 13 with respect to the height Z of the container body 11 is preferably 0.75 <h / Z as shown in the equation (4). Since the upper surface of the solid fuel 13 is close to the opening 12a of the lid 12, it can be easily ignited using a lighter or the like. If h / Z is 0.75 or less, the upper surface of the solid fuel becomes too lower than the opening 12a of the lid body 12, so that ignition becomes difficult.

The ratio (Z / d) of the height Z of the container body 11 to the diameter d of the solid fuel 13 is preferably 0.20 <Z / d <0.60 as shown in the equation (3). As described above, since the upper surface of the solid fuel 13 is set to be close to the opening 12 a of the lid 12, Z / d is substantially the ratio of the height h of the solid fuel 13 to the diameter d of the solid fuel 13. The value approximates to. Therefore, when 0.20 <Z / d <0.60, the amount of burnt residue can be minimized and the solid fuel 13 can be burned well.

If Z / d is 0.20 or less, or Z / d is 0.60 or more, the amount of burnt residue increases, resulting in high costs and an unclear flame disappearance time. It will be difficult to keep warm.

In the solid fuel set 10 for chafing of the present invention, the width {(R−r) / 2} of the edge portion of the lid 12 described in the formula (5) is larger than the diameter d of the solid fuel 13. Small is preferable. If the width {(R−r) / 2} of the edge portion of the lid 12 is larger than or equal to the diameter d of the solid fuel 13, the solid fuel 13 moves in the container body 11, When it comes to be positioned at the corner of the container body 11, it becomes difficult to ignite with a lighter or the like, and burn residue tends to increase, which is not preferable. Since the diameter d of the solid fuel 13 is larger than the width {(R−r) / 2}, the above problem does not occur.

Next, a method for keeping warming the chafing using the chafing solid fuel set of the present embodiment will be described with reference to the drawings. This heat retention method is a representative example, and other heat retention methods may be used as long as the chaining can be kept warm by using the above-described chafing solid fuel set.

FIG. 2 (a) is a perspective view schematically showing an example of a method for keeping warming the chafing using the solid fuel set for chafing of the present embodiment, and FIG. 2 (b) is an example of the chafing. FIG.

As shown in FIG. 2, the chafing 20 used in the present embodiment is provided with legs 22 at the four corners of a substantially rectangular parallelepiped shaped water bath 21 configured to fill hot water, and is fitted into the water bath 21. A plate 23 is provided for accommodating dishes and the like. Furthermore, before providing food to customers, a lid portion 24 having a substantially semi-cylindrical dome shape for covering the food is provided. The lid portion 24 is rotatably fixed to both sides of the container, and can be put into a state where the dish is covered or opened by rotating with a handle.

Furthermore, the solid fuel mounting part 25 for mounting the solid fuel set which concerns on the said embodiment is attached to the bottom part of the container.

Therefore, after the hot water tank 21 constituting the chafing 20 is filled with hot water, the plate 23 is fitted into the hot water tank 21, the prepared dish is placed inside the plate 23, and the solid fuel set 10 is placed on the solid fuel placement portion 25. After that, by igniting the solid fuel 13 placed inside the container body 11, the food in the chafing 20 can be kept at a predetermined temperature for a predetermined time.

The number of the solid fuel sets 10 to be placed inside the solid fuel placement portion 25 is not particularly limited, and two or more sets may be placed depending on the size of the chafing 20 or the like.

Examples that more specifically describe the present invention are shown below, but the present invention is not limited to these examples.

(Examples 1-10 and Comparative Examples 1-9)
First, the solid fuel set 10 for chafing shown in FIG. 1 was prepared. Table 1 below shows the shape of the lid 12 and the container body 11 constituting the solid fuel set for chafing 10 in Examples 1 to 10 and Comparative Examples 1 to 9, and the shape and weight of the solid fuel. In Table 1, the diameter of the opening 12a of the lid 12 is rmm, the height of the container body 11 is Zmm, the diameter of the container body 11 is Rmm, the height of the solid fuel 13 is hmm, the diameter of the solid fuel 13 is dmm, The weight of the solid fuel 13 is Xg.
In addition, as the container main body 11 and the lid body 12, those made of SUS430 were used. Moreover, what solidified alcohol with the soap component was used for the solid fuel.

For this reason, when the solid fuel 13 is ignited, a flame is not generated from the side surface of the solid fuel 13 but only from the upper surface of the solid fuel 13. Accordingly, the flame maintains a more stable shape and the shape of the solid fuel is less likely to collapse, so that more stable heat retention by the flame becomes possible.
Also in the second embodiment, the chafing used in the first embodiment is used, and the dish is kept warm in the same manner as in the first embodiment, but at this time, the warming time can be controlled.
