Description

  The present invention relates to an appliance for preventing a spill from a pan and a cooking container support using the appliance.

  For example, when udon noodles, buckwheat noodles, somen noodles, pasta and other noodles are boiled in a pan, the starch contained in the noodles or the starch starch adhering to the surface of the noodles dissolves in the water. Viscosity becomes higher than this, and it becomes a bubble that is hard to be crushed by wrapping air and water vapor generated from the hot water surface at the time of boiling, and it is blown higher than the liquid surface and spills out of the pan.

  When a spill occurs, the surroundings of the range become soaked with water and becomes dirty, which takes time for maintenance. In addition, the gas fire in the gas range disappears due to the spill, and there is a risk of gas poisoning and gas explosion. For this reason, it is necessary to adjust the heating power frequently or to pour water during cooking. However, adjusting the heating power during cooking to lower heat or watering will lower the heating temperature and lower the temperature at which the noodles are boiled. The feeling may be impaired.

  In addition to boiling noodles, for example, when cooking such as cooking boiled fish or fish, or warming milk or soy milk, spilling of boiled juice or liquid to be heated occurs.

  In order to eliminate such spillage, various proposals have been made to devise the structure of the pan itself, or to provide a spill prevention tool and lid that are separate from the pan.

  For example, in Patent Document 1, the inner bottom surface is a circular plane, the inner surface is a spherical surface whose diameter gradually increases as it goes upward, the diameter ratio between the inner bottom surface and the inner surface, and the height of the pan from the inner bottom surface A pot is described that regulates the relationship of the above to a specific relationship to appropriately promote bubbling of boiled water and boiled juice to enhance the boiling effect, and prevent boiled water and boiled juice from spilling.

  Further, in Patent Document 2, a cylindrical standing portion formed in a hollow shape, and formed continuously with the standing portion so as to spread outward from the lower end of the standing portion, the outer edge is located below the lower end, An umbrella-shaped hem that is open at the outer edge, and at least one first through hole is formed on the upper end side of the standing part, and at least a second through hole is formed in the skirt. One formed blow-out prevention device is described.

  Patent Document 3 describes a pan lid for preventing spillage, which is inclined upward from the lower portion of the peripheral side edge fitted and locked to the opening of the pan and has a blowout hole in the inclined deepest portion.

  In Patent Literature 4, in a pot lid composed of a lid having a concave portion having an opening at the center and an inner lid covering the opening, at least the steps are gradually lowered from the outer peripheral edge of the lid toward the center. There is described a pan lid for preventing spillage formed by forming a single stepped portion and the concave portion having an opening in the center formed continuously at the free end edge of the stepped portion which is the innermost portion.

Japanese Patent No. 2829299 Utility Model Registration No. 3099539 Japanese Utility Model Publication No. 3-76521 Japanese Utility Model Publication No. 61-42504

  However, since the pan described in the above-mentioned Patent Document 1 is a pan having a unique shape with emphasis on convection mainly used for noodle bowls, the inner bottom surface is larger than the upper opening surface compared to a general pan. This is a shape that is not suitable for boiled dishes with low moisture content, such as boiled beans and boiled fish (form boiled), which are small and it is important to cook the entire material at a uniform temperature. In addition, there is a problem that it is expensive to purchase as a dedicated pan for preventing spillage.

  On the other hand, since the spill prevention device described in Patent Document 2 is used by being installed at the bottom of an existing pan, the spill prevention device becomes an obstacle when transferring boiled noodles from a pan to a colander or the like. . Therefore, I want to remove the spill prevention device from the bottom of the pan, but it is difficult to remove because the hem is wide, and the temperature of the device is close to 100 ° C., so it needs to be handled with care, and there is a hindrance to transferring noodles quickly.

  Furthermore, since this blown-out prevention device is mainly intended for noodle bowls, as in Patent Document 1, it is important to cook the whole material uniformly and uniformly, such as boiled beans, boiled fish and boiled fish with a low water content. The structure is unsuitable for cooking. In particular, since there is a need to install this spill-proof device inside the pot, its presence often becomes an obstacle when cooking boiled food. Further, since the shape is complicated, it is difficult to care when sticking occurs.

  Moreover, the pan lid described in the above-mentioned Patent Documents 3 and 4 is intended to eliminate the spilling of the broth during cooking of the simmered food. For this purpose, the center of the pan lid that is inclined so as to become lower toward the center. Is provided with a blowout hole (opening). During cooking, the boiled boiled soup blown from the blowout hole is cooled at the outside temperature, the foam disappears and becomes liquid, and flows into the pan again from the blowout hole. . However, the effect cannot be expected for large-scale spills such as when using noodle bowls. In some cases, for example, when used with a heating cooker with strong thermal power such as an IH cooking heater, Because of the problem of being lifted, it is not suitable for use in noodle bowls.

  Therefore, the present invention can be attached to a hand-held pan having a normal shape, is easy to attach and detach, and can handle a certain size depending on the size of the pan to be attached. An object of the present invention is to provide a spill prevention device that can handle any spillage of cooking, and a cooking container support using the same.

  In order to solve the above-mentioned problem, the pan spill preventive tool of the present invention is used by being installed at the opening of a circular pan, and the top and bottom of the pan spill preventer has a full-open body, and the lower part of the trunk The diameter of the opening is smaller than the diameter of the opening of the pan, and the upper opening of the body is larger than the diameter of the lower opening and the diameter of the opening of the pot. In addition, a frustoconical portion that contacts the opening of the pan is formed.

  The blowout prevention device of the present invention has a simple configuration as a whole, in which the lower opening is smaller than the diameter of the opening of the circular pan and the upper opening is larger than the diameter of the lower opening and the diameter of the opening of the pan. For this reason, the middle part of the torso hits the upper edge of the pan simply by mounting it from the top of the pan to the opening of the pan, and can be easily set in the pan. In addition, since the whole or a part of the body portion has a truncated cone shape, it is possible to deal with a pan whose diameter of the opening of the pan is somewhat different. Therefore, it is not necessary to purchase a new pot in accordance with the spill preventive tool of the present invention, and it can be used as it is for various kinds of hand-held pots.

  If this anti-spill tool is set in a pan and boiled noodles, for example, at the time of boiling, air or steam vaporized in the hot water in the pan will become bubbles that enclose the gas when it comes out from the surface of the hot water. These bubbles are blown up one after another from the surface of the hot pot. These bubbles are blown up one after another from the surface of the hot pot. At this time, first, the growing bubble is guided to the upper body portion by the truncated cone portion of the blowout prevention tool. And, in order to secure a room temperature air layer for cooling more, in a body part designed to have a diameter larger than the diameter of the opening of the pan, a bubble close to 100 ° C. is brought into contact with an air layer having a large temperature difference close to room temperature over a wide range. By forced cooling at once. This causes the foam to lose propulsion energy and disappear without further growth.

The height of the body part of the spill prevention tool shall be set with a sufficient margin than the height at which the foam rising from the opening of the pan disappears.
As described above, the blowout prevention device of the present invention has the upper opening of the trunk portion larger than the diameter of the lower opening and the diameter of the opening portion of the pan, and the opening portion of the pan is formed on the whole or a part of the trunk portion. Since the frustoconical portion is formed so as to abut on the noodles, it is possible to effectively prevent the spilling, so that the noodles can be boiled with the required strong heat for a certain time suitable for noodle bowls. As a result, cooking time can be shortened.

  In addition, in addition to noodle bowls, it is possible to prevent spillage generated from the liquid in the pan during cooking such as cooking of boiled food, milk or soy milk.

  By making the diameter of the lower opening of the body part of the spill prevention device 140 mm or more and the diameter of the upper opening 220 mm or more, it can correspond to a circular pan having a diameter of 140 mm to 220 mm that is usually used, By setting the height of the body part from the opening of the pot to 30 mm or more, it corresponds to the height of the pot being increased by 30 mm or more, so that spillage can be effectively suppressed.

  Moreover, the cooking container support of the present invention is a cooking container support using the above-mentioned pan spill prevention tool, and an arm that spans at least two locations on the upper edge of the trunk of the spill prevention tool. A ring portion having a cooking vessel support hole formed at the center portion of the arm and into which the bottom portion of the cooking vessel is fitted is provided.

There are many dishes that take cooking time even if they continue to heat with a strong fire while avoiding spills by using this anti-spill tool.
For example, when pasta and hand-made udon are heated from water, it is necessary to continue heating for more than 10 minutes or more when the time until the water boils and the time when the noodles are boiled is combined. While the noodles are being boiled, water vapor close to 100 ° C. continues to be released to the upper part of the cylindrical main body of the spill prevention tool. It is a great energy loss to release this as it is in the atmosphere. Therefore, if the sauce and noodle soup for pasta can be heated using the heat of steam during cooking, the heat energy can be effectively used and a plurality of cooking operations can be performed at one time.

  In order to use this cooking container support tool, the arm of the cooking container support tool is supported over two parts of the cylindrical body of the spill prevention tool, and a bowl or the like is cooked in the cooking container support hole in the center ring portion. Place the container so that the bottom of the cooking container is exposed at the top center of the pan. Thereby, it is possible to perform another cooking by effectively using the heat of steam together with the function of preventing spillage.

  According to the present invention, it is an anti-spillage tool that has a body part that is fully open at the top and bottom, and is used by being installed at the opening part of a circular pan, and the lower opening of the body part is smaller than the diameter of the opening part of the pan. The cone has a small diameter, and the upper opening of the body is larger than the diameter of the lower opening and the diameter of the opening of the pan, and a cone that contacts the whole or a part of the body and the opening of the pan By using a blow-off prevention tool with a trapezoidal part, it can be attached to a hand-held pan of normal shape, easy to attach and detach, and can handle a certain size of the size of the pan to be attached, With noodle bowls, it can handle spills of cooking such as boiled food, heating milk and soy milk.

  In addition, the cooking container support of the present invention is formed at the center of the arm, which is stretched over at least two portions of the upper edge of the trunk of the blowout prevention tool, and the bottom of the cooking container is fitted. By providing the ring part which has a cooking container support hole, the heat of the steam which blows off from a pan can be used effectively using a blowing-out prevention tool.

Embodiments of the present invention will be specifically described below with reference to the drawings.
1A and 1B show a blow-out prevention device according to Embodiment 1 of the present invention. FIG. 1A is a perspective view seen from above, and FIG. 1B is a perspective view seen from below. FIG. 2 is a cross-sectional view of a state in which the spill preventer according to the first embodiment is set in a pan.

  The blow-out prevention device 1 according to the first embodiment includes a lower inclined edge portion 2, a frustoconical shape portion 3 thereon, and a body portion 4 thereon. The handle 5 is fixed with rivets or the like. The lower inclined edge 2 has a larger gradient than the frustoconical portion 3, and the lower inclined edge 2 of the lower part from the part where the gradient changes when the upper inclined opening of the pan is mounted and fixed becomes an inclination stopper. It is an important part to increase the stability at the time of wearing. The frustoconical portion 3 is inclined so that it can be accommodated to a certain width depending on the size of the pan to be mounted, and various protrusions unique to the pan (rivets for fixing the handle, screws, etc.) It has a function to avoid.

  Except for the handle 5, the blowout prevention tool 1 can be made of aluminum, stainless steel, copper, heat-resistant glass, thermosetting plastic, or other materials similar to those for the pan. In the case of metal, it can be made by a general manufacturing method such as pressing or spatula drawing. The handle 5 can be made of wood, plastic or the like having low thermal conductivity.

In the first embodiment, as shown in FIG. 2, the inner diameter of the lower end of the lower inclined edge 2 is d1, and the outer diameter of the upper end of the lower inclined edge 2 (the lower end of the frustoconical portion 3) is d2. The outer diameter of the upper end of the truncated cone 3 (the lower end of the barrel 4) is d3, the outer diameter of the upper end of the barrel 4 is d4, the height of the lower inclined edge 2 is h1, and the height of the truncated cone 3 If the height is h2 and the height of the body 4 is h3,
d1 = 174 mm, d2 = 180 mm, d3 = 260 mm, d4 = 270 mm, h1 = 12 mm, h2 = 30 mm, h3 = 80 mm
It was. This can be applied to small pots, medium pots and large pots having a diameter of 180 mm to 260 mm.
Here, in determining the height h <b> 3 of the body portion 4, the following experiment was performed to formulate a dimension that does not cause spillage.
(1) 22cm round pan 3000cc water Pasta 300g (3 servings)
(2) 20cm round pot 1500cc water Somen 150g (3 bundles)
(3) 20cm round pan 2000cc water Somen 200g (4 bundles) + 300cc soy milk
(4) 22cm round pot 800cc water Taro 800g + seasoning (soy sauce, sugar, etc.)
In addition, although the experimental example of (3) is not actual cooking, soy milk was added to 4 bundles of somen, assuming a severe spilled situation.
In the experiments (1) to (4), the height h3 that could withstand the spillage was 80 mm. However, this height is an ideal value, and actually 30 mm to 60 mm is sufficient.

In another example, so that it can correspond to a small pot, a medium pot of caliber 180mm ~ 220mm,
d1 = 174 mm, d2 = 180 mm, d3 = 220 mm, d4 = 230 mm, h1 = 10 mm, h2 = 20 mm, h3 = 90 mm
It can also be. Compared to the previous example, the diameters of d3 and d4 are smaller due to the smaller diameter of the pan.
Of course, these numerical values are merely examples, and the present invention is not limited to these.
For example, d1 = 134 mm can be set in order to correspond to a pan having a diameter of 140 mm. A pan of less than 140 mm is not suitable for cooking with other noodle bowls that may cause spillage, and is not included in this embodiment.

  When this spill prevention device 1 is set in a pan 6-1 to 6-2 and heated with noodle bowls, boiled food, milk or soy milk, bubbles are blown up one after another from the surface of the hot water in the pan, At this time, the growing bubble is guided to the upper body portion 4 by the frustoconical portion 3 of the blowout prevention device 1. And since the diameter of the trunk | drum 4 is designed larger than the diameter of the opening of pan 6-1 to 6-2 so that the room temperature air layer for cooling can be secured more, the bubble near 100 degreeC is near room temperature. Forced cooling is performed at once by contacting a wide range of air layers with a large temperature difference. This causes the foam to lose upward propulsion energy and disappear without further growth. As a result, spillage can be effectively prevented, and cooking such as cooking of boiled food, milk or soy milk can be performed safely and cleanly and safely without frequently adjusting the heating power in the middle.

FIG. 3 is a cross-sectional view showing a blowout prevention device according to Embodiment 2 of the present invention.
The blow-out prevention device 11 according to the second embodiment includes a lower truncated cone part 12 and a body part 13 thereabove, and grips 14 are fixed to both outer sides of the body part 13 by rivets or the like. Yes. Similarly to the spillage prevention device 1 of the first embodiment, this spillage prevention device 11 is also made of aluminum, stainless steel, copper, heat-resistant glass, thermosetting plastic, and other materials similar to the pan except for the handle 14. be able to. The handle 14 can also be made of wood, plastic or the like having low thermal conductivity.

In the second embodiment, as shown in FIG. 3, the outer diameter of the lower end portion of the truncated cone portion 12 is d11, the outer diameter of the upper end portion of the truncated cone portion 12 (the outer diameter of the body portion 13) is d12, the cone When the height of the trapezoidal part 12 is h11 and the height of the body part 13 is h12,
d11 = 172 mm, d12 = 260 mm, h11 = 120 mm, h12 = 30 mm
It is said. In this example, the inner edge of the upper edge corresponds to a pan having a diameter of 180 mm to 240 mm.

  In the case of this Embodiment 2, compared with Embodiment 1, since the height h11 of the frustoconical part 12 is high and the inclination of the slope is steep, in a pot with a small caliber and a large pot, The part to be entered changes greatly as it is shallow or deep. Moreover, if the truncated cone part 12 goes deep inside the pot, it may cause a sense of filth and discomfort depending on the type of cooking. However, except for such a case, the function of preventing spillage can be sufficiently achieved.

Next, an embodiment of the cooking container support of the present invention will be described with reference to FIGS.
FIG. 4 is a perspective view showing an embodiment of the cooking container support of the present invention, FIG. 5 is a perspective view showing a state where the cooking container support is set on the upper part of the blow-out prevention tool, and FIG. 6 is a cooking container support. It is a perspective view which shows the state which set the bowl which is a cooking container to.

  As shown in FIG. 4, the cooking container support 20 is described with respect to the above-described spill prevention tool 1 or 11 (hereinafter, an example in which the spill prevention tool 1 of Embodiment 1 having high stability when the pan is mounted is used). .)) And the cooking vessel support which is formed at the center of the arm 21 and is fitted to the bottom of the cooking vessel having a round bottom such as a bowl. A ring portion 22 having a hole 22a is provided. A handle 23 is attached to the end of the arm 21. The arm 21 is provided with a plurality of holes 24 along the longitudinal direction. This hole 24 may mean a steam vent for allowing steam blown from the lower pan to pass through, or a monitoring hole for confirming the inside of the pan. It is also possible to provide a function as a measuring hole for measuring the amount (bundle) of.

  As a material of the cooking container support 20, an aluminum plate, a stainless steel plate, a copper plate, a wood plate, a heat-resistant plastic plate, etc. can be used except for the handle 23, but metal is preferable in terms of durability and flame retardancy. .

  In this embodiment, the length L to both ends of the arm 21 is set to 380 mm so that it can be set on the body of the spill preventive tool corresponding to the pan having an upper opening of 180 mm to 260 mm. In this example, the inner diameter D1 of the cooking vessel support hole 22a of the ring portion 22 is 150 mm so as to be compatible with a commercially available 150 mm bowl. When a 150 mm bowl with a capacity of about 500 cc is set in the cooking vessel support hole 22a with an inner diameter of 150 mm, the bottom of the hemispherical bowl is almost completely fitted, and the steam heat from the pan is maximized. You may want to lower it. In that case, when the auxiliary ring 25 is placed on the upper part of the ring portion 22 and the bowl is set, the height of the bowl can be increased and the steam heat received from the pan, that is, the cooking temperature can be lowered. By setting the inner diameter D2 of the auxiliary ring 25 to 130 mm, for example, the bowl can be raised by about 35 mm to 40 mm.

  In order to use the cooking container support 20 having the above configuration, as shown in FIG. 5, the upper part of the spill prevention tool 1 mounted on the upper part of the pan 6, the body 4 of the spill prevention tool 1, and the cooking container support tool. Visual alignment is performed so that the 20 ring portions 22 are substantially concentric, and the arm 21 is placed on the upper edge of the body portion of the spill prevention device 1. Next, as shown in FIG. 6, the bowl 30 is placed so that the bottom of the bowl 30 fits into the cooking container support hole 22 a inside the ring portion 22 of the cooking container support 20.

Here, when it is desired to increase the height of the bottom portion of the bowl 30, the auxiliary ring 25 shown in FIG. 4 is placed on the upper portion of the ring portion 22 and then the bowl 30 is set in a hole inside the auxiliary ring 25. The height of the bowl 30 is increased. Thus, by using the auxiliary ring 25, the temperature at which the bowl 30 is cooked by adjusting the steam heat generated from the pan 6 can be adjusted.
Experimentally, 2,000 cc of water is put into a 20 cm round pan, and the bowl 30 is set on the cooking container support 20 placed on the top of the spill prevention tool 1 while boiling 200 g (two servings) of pasta. When 400g of pasta meat sauce was added and heated for 14 minutes, the temperature of the meat sauce was heated to 71 ° C at a room temperature of 32 ° C. Thus, since the meat sauce is also heated to an appropriate temperature at the timing when the pasta is boiled, energy saving of cooking and shortening of the cooking time can be achieved without using another heat source.

As described above, by using the cooking container support 20, it is possible to perform another cooking by effectively using the heat of steam together with the function of preventing spillage.
In addition, as a heat source of the pan used in this invention, it can respond to all systems, such as gas, electric heating, and IH (induction heating).

  The present invention can be attached to a hand-held pan of normal shape, is easy to put on and take off, and can be handled with a certain width depending on the size of the pan to be attached, noodle bowl, boiled food, heating of milk or soy milk, etc. It can be suitably used in the field of cooking utensils as a spill preventive tool that can handle any spillage of cooking and a cooking container support using the same.
