FIG. 1 is a plan view, a front view, and a sectional view taken along line AA of the baking table according to the first embodiment, and FIG. 2 is a side view and a sectional view taken along the line BB of the baking table according to the first embodiment.
As shown in FIGS. 1 (A) to 1 (C) and FIG. 2 (A), the baking table according to the first embodiment is formed of a substantially rectangular parallelepiped ceramic plate 1 having a length of 135 mm, a width of 230 mm, and a thickness of 5 mm. There is.
The ceramic plate 1 is provided with seven rectangular holes 2 having a length of 20 mm and a width of 8 mm in a matrix of seven in the horizontal direction and three in the vertical direction at equal intervals, and the upper edge of the ceramic plate 1 is provided. And the distance between the top edge of the matrix-shaped hole 2, the distance between the lower edge of the ceramic plate 1 and the bottom edge of the matrix-shaped hole 2, the left edge of the ceramic plate 1 and the leftmost side of the matrix-shaped hole 2. The distance between the ceramic plate 1 and the right edge of the ceramic plate 1 and the rightmost side of the matrix-shaped hole 2 are both 15 mm.
Further, as shown in FIGS. 1 (A), 1 (C) and 2 (B), a ridge having a width of 5 mm, a height of 1.5 mm and an inner tapered surface is formed around both surfaces of the ceramic plate 1. 3 is provided, and ridges 4 having a width of 1 mm, a height of 1 mm, and a tapered surface on the outside are provided around both sides of each hole 2. Therefore, the thickness of the periphery of the baking table according to the first embodiment is 8 mm.
Further, the ceramic plate 1, the ridges 3 and the ridges 4 in Example 1 are formed by mixing 20% by weight or 30% by weight of silicon carbide with heat-resistant clay, molding them into the shapes shown in FIGS. 1 and 2, and then firing them. Manufactured. Therefore, when the baking table according to the first embodiment is placed inside the microwave oven and irradiated with microwaves, the silicon carbide generates heat and the ceramic plate 1 is also heated.

実施例1のセラミック板1は、上記のような構造及び材質であるため、実施例1に係るパン焼き台を用いると、セラミック板1の上面に被調理物を載せてオーブントースターの内部に置いて加熱した場合は、上方にある熱源から熱線は被調理物に直接照射され、下方にある熱源からの熱線はセラミック板1に照射されるとともに、マトリクス状の穴2を通して被調理物にも照射され、かつ、熱せられたセラミック板1からの赤外線及び遠赤外線が被調理物に照射されるので、パン等の被調理物を効率的に加熱調理することができる。
なお、耐熱陶土に炭化珪素を20重量%混入させたセラミック板の遠赤外線放射率(波長範囲3.33〜20μmにおける積分放射率)を、ヒーター温度100℃で計測した結果88.6%であり、耐熱陶土に炭化珪素を30重量%混入させたセラミック板の遠赤外線放射率を、同条件で計測した結果87.7%であった。そして、一般的な陶器の遠赤外線放射率は、65〜75%程度であることから、実施例1のセラミック板1は、赤外線及び遠赤外線を効率的に被調理物へ照射できることが分かる。
また、同様にして電子レンジの内部で加熱した場合は、マイクロ波によって被調理物が加熱されるとともに、マイクロ波の照射によりセラミック板1も熱せられるので、パン等の表面に焦げ目を付けることができる。
さらに、セラミック板1の両面の周囲に突条3が設けられ、各穴2の両面の周囲に凸条4が設けられているので、セラミック板1のどちらの面を上面として用いても、その上面に載せたパン、ピザ、肉まん等がセラミック板1から滑り落ちにくく、また、これらを載せてオーブントースターや電子レンジの内部で加熱した時に、セラミック板1の上面の周囲や各穴2の周囲に落ちたパンくずや水滴等が、セラミック板1の縁や穴2からこぼれ落ちるのを防止できる。
Since the ceramic plate 1 of the first embodiment has the above-mentioned structure and material, when the pan baking table according to the first embodiment is used, the object to be cooked is placed on the upper surface of the ceramic plate 1 and placed inside the oven toaster. When heated, heat rays from the heat source above are directly applied to the object to be cooked, heat rays from the heat source below are applied to the ceramic plate 1 and also to the object to be cooked through the matrix-shaped holes 2. Moreover, since the infrared rays and far infrared rays from the heated ceramic plate 1 are applied to the object to be cooked, the object to be cooked such as bread can be efficiently cooked.
The far-infrared emissivity (integrated emissivity in the wavelength range of 3.33 to 20 μm) of a ceramic plate in which 20% by weight of silicon carbide was mixed with heat-resistant ceramic soil was measured at a heater temperature of 100 ° C. and was 88.6%. The far-infrared emissivity of a ceramic plate in which 30% by weight of silicon carbide was mixed with heat-resistant ceramic soil was measured under the same conditions and found to be 87.7%. Since the far-infrared emissivity of general pottery is about 65 to 75%, it can be seen that the ceramic plate 1 of Example 1 can efficiently irradiate the object to be cooked with infrared rays and far-infrared rays.
Further, when the food is heated inside the microwave oven in the same manner, the object to be cooked is heated by the microwave and the ceramic plate 1 is also heated by the irradiation of the microwave, so that the surface of the bread or the like may be browned. it can.
Further, since the ridges 3 are provided around both sides of the ceramic plate 1 and the ridges 4 are provided around both sides of each hole 2, no matter which side of the ceramic plate 1 is used as the upper surface, the ridges 4 are provided. Bread, pizza, meat buns, etc. placed on the upper surface do not easily slip off from the ceramic plate 1, and when these are placed and heated inside an oven toaster or microwave oven, the circumference of the upper surface of the ceramic plate 1 and the circumference of each hole 2 It is possible to prevent bread scraps, water droplets, and the like that have fallen on the ceramic plate 1 from spilling from the edges and holes 2 of the ceramic plate 1.

The ceramic plate 11 was provided with five circular holes 12 having a diameter of 4 mm at equal intervals in a matrix of five in the horizontal direction and three in the vertical direction. The total number may be determined in consideration of the main use of the baking table and the vertical and horizontal lengths of the ceramic plates 1 and 11.
For example, when the dimensions of the ceramic plates 1 and 11 are 100 mm in length and 150 mm in width, the area is 10 to 300 mm 2 . The diameter is 3.5 to 19 mm), and 5 to 7 pieces can be selected in the horizontal direction and 2 to 4 pieces in the vertical direction. When the dimensions of the ceramic plates 1 and 11 are 250 mm in length and 300 mm in width, the area is large. 30-1200 mm 2 rectangles, circles or ellipses (6-40 mm in length, 5-30 mm in width, 6-39 mm in diameter in the case of circles), 7-12 in the horizontal direction, 4 to 4 in the vertical direction You can choose from eight.
Further, the arrangement of the plurality of holes 2 and 12 does not have to be in a matrix shape, and when the size of the ceramic plate 1 is 100 mm in length and 150 mm in width while considering the size of the holes 2 and 12, 10 to 30 pieces are used.

また、耐熱陶土等の陶磁器原料に混入させる炭化珪素の含有量は、10重量%未満だとマイクロ波の吸収と発熱の効果が得られず、50重量%を超えると陶磁器の成型が困難となるため、10〜50重量%が好ましく、20〜40重量%がより好ましい。
同様に、陶磁器原料に混入させる金属酸化物の含有量は、5重量%未満だとマイクロ波の吸収と発熱の効果が得られず、50重量%を超えると陶磁器の成型が困難となるため、5〜50重量%が好ましく、8〜12重量%がより好ましい。
さらに、炭化珪素や金属酸化物を含有する陶磁器製の板に代えて、両面若しくは片面にマイクロ波吸収発熱物質からなる発熱層を設けた陶磁器製の板とすることによっても、電子レンジによる加熱調理において、被調理物の表面に焦げ目を付けることができる。
なお、マイクロ波吸収発熱物質の一例としては、フェライト粉等の透磁率が大きい粉末を、シリコン樹脂、水ガラス、シリカゾル等のバインダーに60〜80重量%加えて塗料化したものが挙げられる。そして、両面に発熱層を設けた場合は、どちらを上面にしても被調理物の表面に焦げ目を付けることができ、片面に発熱層を設けた場合は、被調理物の表面に焦げ目を付けるか否かを選択することができる。
(3) Around both sides of the ceramic plates 1 and 11 of Examples 1 and 2, the widths of the ridges 3 and 13 having a width of 5 mm and a height of 1.5 mm and the widths of both sides of the holes 2 and 12 are formed. Hemispherical protrusions 15 having a diameter of 1.4 mm and a height of 0.7 mm were provided on both sides of the protrusions 4 and 14 having a height of 1 mm and a height of 1 mm, and the ceramic plate 11 of the second embodiment. However, these may be provided on only one side, and the ridges 4, the protrusions 14, and the protrusions 15 may not be provided.
When the ridges 4, the protrusions 14, and the protrusions 15 are not provided, bread crumbs, water droplets, and the like are likely to spill out, but the food to be cooked adheres to the surfaces of the ceramic plates 1 and 11, so that there is an advantage that they are easily browned. There is.
Further, the dimensions of the ridges 3 and 13, the ridges 4 and the protrusions 14 may be such that the bread or the like does not easily slip off and the bread crumbs or water droplets can be prevented from spilling. Not limited to the dimensions, the ridges 3 and 13 may have a width of 1 to 10 mm and a height of 1 to 5 mm, and the ridges 4 and 14 have a width of 0.5 to 5 mm and a height of the ridges. The height may be 3 or 13 or less and the range may be 0.5 to 3 mm.
(4) The ceramic plates 1, 11, the ridges 3, 13 and the ridges 4 and 14 in Examples 1 and 2 are fired after molding by mixing 20% by weight or 30% by weight of silicon carbide with heat-resistant porcelain clay. Although it was a ceramic plate manufactured in the above process, metal oxides such as iron oxide and alumina may be mixed in place of silicon carbide, and the surface of the object to be cooked may be browned during heating in a microwave oven. If it is not necessary to attach it, it may be a ceramic plate manufactured by molding without mixing silicon carbide or metal oxide with an appropriate ceramic raw material and then firing.
Further, if the content of silicon carbide mixed in the ceramic raw material such as heat-resistant clay is less than 10% by weight, the effect of microwave absorption and heat generation cannot be obtained, and if it exceeds 50% by weight, it becomes difficult to mold the earthenware. Therefore, 10 to 50% by weight is preferable, and 20 to 40% by weight is more preferable.
Similarly, if the content of the metal oxide mixed in the earthenware raw material is less than 5% by weight, the effects of microwave absorption and heat generation cannot be obtained, and if it exceeds 50% by weight, it becomes difficult to mold the earthenware. 5 to 50% by weight is preferable, and 8 to 12% by weight is more preferable.
Further, instead of the ceramic plate containing silicon carbide or metal oxide, a ceramic plate having a heat generating layer made of a microwave absorbing heat generating substance on both sides or one side can be used for cooking in a microwave oven. In, the surface of the object to be cooked can be browned.
As an example of the microwave-absorbing pyrogen, a powder having a high magnetic permeability such as ferrite powder is added to a binder such as silicon resin, water glass, or silica sol in an amount of 60 to 80% by weight to form a paint. When the heat generating layer is provided on both sides, the surface of the object to be cooked can be browned regardless of which side is the upper surface, and when the heat generating layer is provided on one side, the surface of the object to be cooked is browned. You can choose whether or not.
