發明所要解決的課題The problem to be solved by the invention

在多線圈型的IH方式的電飯煲中，根據線圈的形狀或配置，加熱方式會發生大的變化。但是，在專利文獻1、2的多線圈型的電飯煲中，沒有對線圈的形狀或配置進行詳細研究，以抑制加熱不均勻的觀點在線圈的形狀或配置上有值得改進的地方。In a multi-coil type IH type rice cooker, the heating method greatly changes depending on the shape and arrangement of the coils. However, in the multi-coil type rice cookers disclosed in Patent Documents 1 and 2, the shape and arrangement of the coils are not studied in detail, and there is a point for improvement in the shape and arrangement of the coils from the viewpoint of suppressing heating unevenness.

本發明的課題是在多線圈型的IH型的烹飪器中抑制加熱不均勻。An object of the present invention is to suppress uneven heating in a multi-coil type IH type cooker.

用於解決課題的技術方案Technical solutions for solving problems

本發明提供一種烹飪器，該烹飪器具備鍋和多個線圈，所述鍋呈帶底圓筒狀，具有鍋底部、鍋側部及彎曲部，所述彎曲部連接所述鍋底部與所述鍋側部，所述多個線圈配置於所述鍋的至少所述鍋底部及所述彎曲部的外側，所述線圈俯視時具有橢圓形狀，並被配置為：所述橢圓形狀的長軸沿所述鍋的周向，且所述線圈的中心比所述鍋側部更靠近所述鍋底部。The invention provides a cooker, the cooker is provided with a pot and a plurality of coils, the pot is cylindrical with a bottom, and has a pot bottom, a pot side and a curved portion, and the curved portion connects the pot bottom and the the side part of the pot, the plurality of coils are arranged on at least the bottom of the pot and the outer side of the curved part of the pot, the coils have an elliptical shape in plan view, and are arranged so that the long axis of the ellipse shape is along the The circumference of the pan, and the center of the coil is closer to the bottom of the pan than the side of the pan.

根據該結構，由於多個線圈配置於鍋的至少鍋底部及彎曲部的外側，因此線圈為立體配置，而不是平面配置。這樣，通過進行立體的加熱能夠抑制加熱不均勻。另外，由於線圈配置為線圈的中心比鍋側部更靠近鍋底部，因此能夠對鍋底部進行相對較大的加熱。特別是，在電飯煲或進行煮燉烹飪的烹飪器中，通過對鍋底部進行程度大的加熱，鍋中能夠產生上下方向的對流。其結果，能夠很好地混合被烹飪物，從而能夠抑制加熱不均勻。此外，所謂鍋的“帶底圓筒狀”並不僅限於嚴格意義上的圓筒，也包含在鍋側部有坡度的那樣的圓錐狀的形狀。另外，鍋底部、鍋側部及彎曲部為通過曲率劃分的部分，各部分並不限於平坦。並且，彎曲部可以是連接鍋底部和鍋側部的R部（焊腳部）等的角部。According to this configuration, since the plurality of coils are arranged at least on the outer side of the pan bottom and the bent portion of the pan, the coils are arranged three-dimensionally, not planarly. In this way, heating unevenness can be suppressed by performing three-dimensional heating. In addition, since the coil is arranged so that the center of the coil is closer to the bottom of the pan than the sides of the pan, it is possible to heat the bottom of the pan relatively greatly. In particular, in a rice cooker or a cooker for simmering cooking, convection in the vertical direction can be generated in the pot by heating the bottom of the pot to a large extent. As a result, the to-be-cooked material can be mixed well, and heating unevenness can be suppressed. In addition, the so-called "bottomed cylindrical shape" of the pot is not limited to a cylinder in the strict sense, but also includes a conical shape having a slope on the side of the pot. In addition, the pot bottom part, the pot side part, and the curved part are parts divided by curvature, and each part is not limited to being flat. In addition, the bent portion may be a corner portion such as an R portion (leg portion) connecting the pot bottom portion and the pot side portion.

所述線圈可以延伸到所述鍋的所述鍋側部的外側。The coils may extend outside the pot sides of the pot.

根據該結構，由於多個線圈配置於鍋的鍋底部、彎曲部及鍋側部的外側，因此通過進行更加立體的加熱能夠抑制加熱不均勻。According to this configuration, since the plurality of coils are arranged on the outer sides of the pan bottom, the curved portion, and the pan side portion of the pan, it is possible to suppress uneven heating by performing more three-dimensional heating.

所述橢圓形狀的短軸方向的寬度可以為92mm以上且110mm以下。The width in the short-axis direction of the elliptical shape may be 92 mm or more and 110 mm or less.

根據該結構，如上所述規定線圈的面積時，由於規定了短軸方向的寬度的上下限，因此能夠具體設計線圈的形狀。本發明的發明人們在實驗中證實了，特別是，短軸方向的寬度在上述範圍時，在電飯煲或進行煮燉烹飪的烹飪器中，鍋內產生對流，從而能夠很好地混合被烹飪物。According to this configuration, when the area of the coil is specified as described above, since the upper and lower limits of the width in the short-axis direction are specified, the shape of the coil can be specifically designed. The inventors of the present invention have confirmed through experiments that, in particular, when the width in the short-axis direction is within the above-mentioned range, in a rice cooker or a cooker for simmering cooking, convection is generated in the pot, and the food to be cooked can be well mixed. .

在相鄰的所述線圈間可以設有間隙。A gap may be provided between the adjacent coils.

根據該結構，由於線圈彼此不接觸，因此線圈之間不導熱。由此，通過各線圈能夠加熱各部分。另外，由於線圈彼此不重疊，因此能夠固定來自各線圈的感應加熱量。換言之，若存在線圈彼此重疊的部分，則在重疊的部分中到鍋的距離根據線圈而不同，感應加熱量有可能不固定，但該結構能夠防止這個問題。According to this structure, since the coils are not in contact with each other, heat is not conducted between the coils. Thereby, each part can be heated by each coil. In addition, since the coils do not overlap each other, the amount of induction heating from each coil can be fixed. In other words, if there is a portion where the coils overlap each other, the distance to the pan varies depending on the coil in the overlapped portion, and the amount of induction heating may not be constant, but this structure can prevent this problem.

所述間隙可以為10mm以上且50mm以下。The gap may be 10 mm or more and 50 mm or less.

根據該結構，線圈間的間隙為10mm以上，通過該間隙對配置各線圈的區域進行分區。由此，通過各線圈能夠加熱各部分。另外，線圈間的間隙為50mm以下，減少非加熱區域從而能夠均勻地加熱。According to this configuration, the gap between the coils is 10 mm or more, and the region where each coil is arranged is divided by the gap. Thereby, each part can be heated by each coil. In addition, the gap between the coils is 50 mm or less, and the non-heating area can be reduced to enable uniform heating.

所述烹飪器可以還具備鍋容置部，所述鍋容置部呈帶底圓筒狀，容置所述鍋，並具有底部、側部及曲部，所述底部配置於所述鍋底部的外側，所述側部配置於所述鍋側部的外側，所述曲部配置於所述彎曲部的外側，並連接所述底部與所述側部，在所述鍋容置部的所述曲部可以設置有線圈安裝部，所述線圈安裝部呈沿所述線圈的內部形狀的圓弧狀。The cooker may further include a pot accommodating portion, the pot accommodating portion is cylindrical with a bottom, accommodates the pot, and has a bottom portion, a side portion and a curved portion, and the bottom portion is arranged at the bottom of the pot. the outer side of the pot, the side portion is arranged on the outer side of the pot side portion, the curved portion is arranged on the outer side of the curved portion, and connects the bottom portion and the side portion, and is located on the outer side of the pot accommodating portion. The curved portion may be provided with a coil mounting portion having a circular arc shape along the inner shape of the coil.

根據該結構，通過在鍋容置部的曲部安裝線圈，能夠積極地對鍋的彎曲部進行加熱，因此能夠實現立體的加熱。特別是，由於線圈安裝部為沿線圈的內部形狀的圓弧狀，因此能夠準確定位並安裝線圈。此外，所謂鍋容置部的“帶底圓筒狀”並不僅限於嚴格意義上的圓筒，也包含在側部有坡度的圓錐狀的形狀。另外，底部、側部及曲部為通過曲率劃分的部分，各部分並不限於平坦。並且，曲部可以為連接底部和側部的R部（焊腳部）等的角部。According to this configuration, by attaching the coil to the curved portion of the pot accommodating portion, the curved portion of the pot can be actively heated, so that three-dimensional heating can be realized. In particular, since the coil mounting portion has an arc shape along the inner shape of the coil, the coil can be accurately positioned and mounted. In addition, the so-called "bottomed cylindrical shape" of the pot accommodating portion is not limited to a cylinder in the strict sense, but also includes a conical shape having a sloped side portion. In addition, the bottom part, the side part, and the curved part are parts divided by curvature, and each part is not limited to being flat. In addition, the curved portion may be a corner portion such as an R portion (leg portion) connecting the bottom portion and the side portion.

發明效果Invention effect

根據本發明，在多線圈型的IH方式的烹飪器中，由於配置為線圈的橢圓形狀的長軸沿鍋的周向，且線圈的中心比鍋的鍋側部更靠近鍋底部，因此鍋內產生對流，從而能夠抑制加熱不均勻。According to the present invention, in the multi-coil type IH type cooker, since the long axis of the ellipse shape of the coil is arranged in the circumferential direction of the pan, and the center of the coil is closer to the bottom of the pan than the pan side of the pan, the inside of the pan is Convection is generated, whereby uneven heating can be suppressed.

第7圖是表示鍋10、鍋容置部131和線圈150的位置關係的剖視圖。FIG. 7 is a cross-sectional view showing the positional relationship between the pan 10 , the pan accommodating portion 131 , and the coil 150 .

線圈150配置於鍋10的鍋底部10a、鍋側部10b及彎曲部10c的外側。另外，線圈150與鍋容置部131的底部131a、側部131b及曲部131c的外表面抵接。從促進煮飯時的對流的觀點，線圈150優選配置於至少鍋底部10a及彎曲部10c的外側，即，優選抵接於至少鍋容置部131的底部131a及曲部131c。The coil 150 is arranged on the outside of the pot bottom portion 10 a , the pot side portion 10 b , and the curved portion 10 c of the pot 10 . In addition, the coil 150 is in contact with the bottom portion 131 a , the side portion 131 b , and the outer surfaces of the curved portion 131 c of the pot accommodating portion 131 . From the viewpoint of promoting convection during rice cooking, the coil 150 is preferably disposed at least outside the pot bottom 10a and the curved portion 10c, that is, preferably in contact with at least the bottom 131a and the curved portion 131c of the pot accommodating portion 131 .

從鍋10的中心軸L朝向徑向外側，定義到線圈150的中心的距離d1，到彎曲部10c的中央的距離d2。此時，距離d1比距離d2小。即，線圈150配置為線圈150的中心比鍋側部10b更靠近鍋底部10a。由此，線圈150對鍋10的鍋底部10a進行相對較大的加熱。The distance d1 to the center of the coil 150 and the distance d2 to the center of the bent portion 10c are defined from the center axis L of the pan 10 toward the radially outer side. At this time, the distance d1 is smaller than the distance d2. That is, the coil 150 is arranged such that the center of the coil 150 is closer to the pot bottom 10a than the pot side 10b. Thereby, the coil 150 heats the pot bottom 10a of the pot 10 relatively largely.

第8圖是表示線圈150的配置的鍋10的仰視圖。第8圖為了表示線圈150和鍋10的位置關係沒有圖示出鍋容置部件130，原來如第7圖所示在線圈150和鍋10之間夾入鍋容置部件130。線圈150配置為線圈150的橢圓形狀的長軸沿鍋10的周向。FIG. 8 is a bottom view of the pot 10 showing the arrangement of the coils 150 . In FIG. 8 , the pan accommodating member 130 is not shown in order to show the positional relationship between the coil 150 and the pan 10 . As shown in FIG. 7 , the pan accommodating member 130 is sandwiched between the coil 150 and the pan 10 . The coil 150 is arranged such that the long axis of the elliptical shape of the coil 150 is along the circumferential direction of the pot 10 .

在本實施方式中，線圈150的短軸方向的寬度（短徑w1）例如為97mm，長軸方向的寬度（長徑w2）例如為120mm。線圈150的橢圓形狀並不限於該數值，但優選地，如下所示短軸方向的寬度為92mm以上且110mm以下。In the present embodiment, the width in the short axis direction (the short diameter w1 ) of the coil 150 is, for example, 97 mm, and the width in the long axis direction (the long diameter w2 ) is, for example, 120 mm. The elliptical shape of the coil 150 is not limited to this numerical value, but preferably, the width in the short-axis direction as shown below is 92 mm or more and 110 mm or less.

在第8圖所示的線圈150a～150c的配置中，各線圈150a～150c相互不接觸，隔開間隙D進行配置。優選地，該間隙D為10mm以上且50mm以下。在本實施方式中，該間隙D例如為26mm。In the arrangement of the coils 150 a to 150 c shown in FIG. 8 , the respective coils 150 a to 150 c do not contact each other and are arranged with a gap D therebetween. Preferably, the gap D is 10 mm or more and 50 mm or less. In the present embodiment, the gap D is, for example, 26 mm.

本發明的發明人們在實驗中證實了通過將線圈150的短軸方向的寬度規定為92mm以上且110mm以下，稱為Brix值的米飯的美味成分變大。在實驗中，使用5.5合容量和10合容量的兩種容量的電飯煲，在本實施方式的線圈150的配置下，只變更線圈150的短軸方向的寬度，對Brix值進行測定。在短軸方向的寬度的變更中，在使配置有線圈150的鍋10的徑向的最內點一致的狀態下，以向徑向外側增大線圈150的條件進行實驗。在實驗中，線圈150的基線數設為45根，匝數設為23匝。此外，進行其他實驗，線圈150的基線數設為25根，匝數設為24匝，但沒有發現大的變化，也同時證實了作為影響要素大的要素是線圈150的面積。另外，線圈150的內部形狀設為短徑34mm、長徑62mm。實驗結果如下面的【表1】、【表2】所示。The inventors of the present invention have confirmed in experiments that by making the width of the coil 150 in the short-axis direction to be 92 mm or more and 110 mm or less, the deliciousness component of the rice called Brix value increases. In the experiment, the Brix value was measured by changing only the width in the short-axis direction of the coil 150 under the arrangement of the coil 150 in the present embodiment using rice cookers with two capacities, 5.5% and 10%. In changing the width in the short-axis direction, experiments were conducted under the condition that the coils 150 were enlarged radially outward in a state where the innermost points in the radial direction of the pan 10 in which the coils 150 were arranged were aligned. In the experiment, the number of base lines of the coil 150 was set to 45, and the number of turns was set to 23 turns. In addition, another experiment was conducted, and the number of base lines of the coil 150 was set to 25 and the number of turns was set to 24, but no significant change was found, and it was also confirmed that the area of the coil 150 was the most influential factor. In addition, the inner shape of the coil 150 was set to a short diameter of 34 mm and a long diameter of 62 mm. The experimental results are shown in the following [Table 1] and [Table 2].

參照【表1】，線圈150的短軸方向的寬度為92～102mm，能夠得到良好的Brix值。參照【表2】，線圈150的短軸方向的寬度為100～110mm，能夠得到良好的Brix值。因此，線圈150的短軸方向的寬度優選為92～110mm，更優選為100～102mm。Referring to [Table 1], the width in the short-axis direction of the coil 150 is 92 to 102 mm, and a good Brix value can be obtained. Referring to [Table 2], the width in the short-axis direction of the coil 150 is 100 to 110 mm, and a good Brix value can be obtained.

第9圖是表示線圈150的配置的鍋容置部131的仰視圖。FIG. 9 is a bottom view of the pan accommodating portion 131 showing the arrangement of the coils 150 .

在鍋容置部131的曲部131c設置有線圈安裝部131e，所述線圈安裝部131e呈沿線圈150的內部形狀的圓弧狀。在本實施方式中，線圈安裝部131e沿鍋容置部131的周向設有多個，對於各線圈150a～150c各設有兩個，共計6個。與各線圈150a～150c分別對應的每兩個線圈安裝部131e相互對置，與各線圈150a～150c的長軸方向的內端接觸。A coil mounting portion 131 e is provided on the curved portion 131 c of the pot accommodating portion 131 , and the coil mounting portion 131 e has an arc shape along the inner shape of the coil 150 . In the present embodiment, a plurality of coil mounting portions 131e are provided along the circumferential direction of the pan accommodating portion 131, and two coils 150a to 150c are provided for each, for a total of six coils. The two coil attachment portions 131e corresponding to the respective coils 150a to 150c are opposed to each other, and are in contact with the inner ends of the respective coils 150a to 150c in the longitudinal direction.

線圈150a～150c為了通電及控制經由未圖示的電線分別電連接於控制基板140、141（參照第5圖）。在本實施方式中，線圈150a～150c都是相同的。經由上述電線，能夠向線圈150a～150c分別獨立地通電。The coils 150 a to 150 c are electrically connected to the control boards 140 and 141 (see FIG. 5 ), respectively, through electric wires not shown for energization and control. In this embodiment, the coils 150a to 150c are all the same. The coils 150a to 150c can be independently energized through the above-mentioned electric wires.

在本實施方式中，通過以下方式進行控制，即，如下所述在適當的定時從控制基板140、141向線圈150通高頻電流。In the present embodiment, control is performed by supplying a high-frequency current from the control boards 140 and 141 to the coil 150 at appropriate timing as described below.

參照第6圖，例如，若只向線圈150a通高頻電流，則對與線圈150a對應的鍋10（參照第4圖）的底面部到側面部的上下方向（縱向）的大的區域進行局部感應加熱。通過集中地加熱該加熱區域，在鍋10內的該加熱區域產生上下方向的大的對流。通過上下方向的大的對流得到大的攪拌效果，在煮飯中，能夠得到米飯所包含的美味成分（溶出糖分等）。此外，為了集中地加熱該加熱區域，依賴線圈150的加熱輸出，但優選地至少通電0.5秒左右。例如，從0.5秒到30秒只向線圈150a通電。Referring to FIG. 6 , for example, when only a high-frequency current is applied to the coil 150 a , a localized area of the pan 10 (refer to FIG. 4 ) corresponding to the coil 150 a in the vertical direction (longitudinal direction) from the bottom surface to the side surface. Induction heating. By heating the heating region intensively, large convection in the vertical direction is generated in the heating region in the pot 10 . A large stirring effect is obtained by the large convection in the up-down direction, and delicious ingredients (elution of sugar, etc.) contained in the rice can be obtained during rice cooking. In addition, in order to heat this heating area intensively, it is preferable to energize at least about 0.5 second depending on the heating output of the coil 150 . For example, only coil 150a is energized from 0.5 seconds to 30 seconds.

同樣地，若在上述時間只向線圈150b通高頻電流，則對與線圈150b對應的鍋10的底面部到側面部的上下方向（縱向）的大的區域進行局部感應加熱，在鍋10內的該加熱區域產生上下方向的大的對流。另外，若在上述時間只向線圈150c通高頻電流，則對與線圈150c對應的鍋10的底面部到側面部的上下方向（縱向）的大的區域進行局部感應加熱，在鍋10內的該加熱區域產生上下方向的大的對流。Similarly, when only the high-frequency current is applied to the coil 150b at the above-mentioned time, local induction heating is performed on a large area in the vertical direction (longitudinal direction) from the bottom surface to the side surface of the pan 10 corresponding to the coil 150b, and inside the pan 10 This heating area of produces large convection in the upper and lower directions. In addition, if only the high-frequency current is applied to the coil 150c at the above-mentioned time, local induction heating is performed on a large area in the vertical direction (longitudinal direction) from the bottom surface to the side surface of the pan 10 corresponding to the coil 150c, and the inner surface of the pan 10 is heated by local induction. This heating area generates large convection in the up-down direction.

這樣，例如，若只向線圈150a通電，而使其他線圈150b、150c為非通電，則對與通電的線圈150a對應的鍋10的底面部到側面部的上下方向（縱向）的大的區域進行局部感應加熱，在鍋10內的該加熱區域產生上下方向的大的對流。即，通過通電形成的局部的加熱區域和通過非通電形成的非加熱區域之間的的溫度差變大，產生大的對流，因此能夠得到大的攪拌效果。In this way, for example, when only the coil 150a is energized, and the other coils 150b and 150c are de-energized, a large area in the vertical direction (vertical direction) from the bottom surface to the side surface of the pan 10 corresponding to the energized coil 150a is performed. Local induction heating generates large convection in the vertical direction in the heating area in the pot 10 . That is, since the temperature difference between the local heating area formed by energization and the non-heating area formed by non-energization increases, large convection occurs, and thus a large stirring effect can be obtained.

接下來，若只向位於線圈150a的相鄰位置的線圈150b通電，而使其他線圈150a、150c為非通電，則對與通電的線圈150b對應的鍋10的底面部到側面部的上下方向（縱向）的大的區域進行局部感應加熱，在鍋10內的該加熱區域產生上下方向的大的對流。並且，若只向位於線圈150b的相鄰位置的線圈150c通電，而使其他線圈150a、150b為非通電，則對與通電的線圈150c對應的鍋10的底面部到側面部的上下方向（縱向）的大的區域進行局部感應加熱，在鍋10內的該加熱區域產生上下方向的大的對流。Next, when only the coil 150b located adjacent to the coil 150a is energized, and the other coils 150a and 150c are de-energized, the vertical direction ( A large area in the vertical direction) is locally induction heated, and large convection in the vertical direction is generated in this heating area in the pot 10 . Furthermore, when only the coil 150c located adjacent to the coil 150b is energized, and the other coils 150a and 150b are de-energized, the vertical direction (vertical direction) from the bottom part to the side part of the pan 10 corresponding to the energized coil 150c is energized. ) is subjected to local induction heating, and large convection in the vertical direction is generated in the heating region in the pot 10 .

因此，能夠通過以下方式進行控制，即，依次進行：向多個線圈150中的某個線圈通電後，向位於某個線圈的相鄰位置的其他線圈通電，並使除其他線圈以外的線圈為非通電。根據該控制，通過局部加熱產生的上下方向的大的對流在鍋10的周向依次移動，在鍋10內能夠產生上下方向的對流及周向的對流結合形成的對流。通過結合形成的對流在煮飯中能夠進一步獲得米飯所包含的美味成分（溶出糖分等）。Therefore, it is possible to perform control by sequentially energizing one of the plurality of coils 150, then energizing the other coils located adjacent to the certain coil, and making the coils other than the other coils energized. Not powered. According to this control, the large vertical convection generated by the local heating moves sequentially in the circumferential direction of the pan 10 , and convection in which the vertical convection and the circumferential convection are combined can be generated in the pan 10 . The convection formed by the combination can further obtain delicious ingredients (dissolved sugar, etc.) contained in the rice during cooking.

根據本實施方式的電飯煲1，具有以下優點。According to the rice cooker 1 of this embodiment, there are the following advantages.

由於多個線圈150配置於鍋10的至少鍋底部10a及彎曲部10c的外側，因此線圈為立體配置，而不是平面配置。這樣，通過進行立體的加熱能夠抑制加熱不均勻。另外，由於線圈150配置為線圈150的中心比鍋側部更靠近鍋底部10a，因此能夠對鍋底部10a進行相對較大的加熱。通過對鍋底部10a進行程度大的加熱，鍋10中能夠產生上下方向的對流。其結果，能夠很好地混合米飯，能夠抑制加熱不均勻並能夠提高Brix值。Since the plurality of coils 150 are arranged at least on the outer sides of the pot bottom 10a and the bent portion 10c of the pot 10, the coils are arranged three-dimensionally, not planarly. In this way, heating unevenness can be suppressed by performing three-dimensional heating. In addition, since the coil 150 is arranged such that the center of the coil 150 is closer to the pan bottom 10a than the pan side, it is possible to relatively heat the pan bottom 10a. By heating the pot bottom 10a to a large extent, convection in the vertical direction can be generated in the pot 10 . As a result, the rice can be mixed well, the uneven heating can be suppressed, and the Brix value can be increased.

由於3個線圈150配置於鍋10的鍋底部10a、彎曲部10c及鍋側部10b的外側，因此通過進行更加立體的加熱能夠抑制加熱不均勻。Since the three coils 150 are arranged on the outer sides of the pan bottom 10a, the curved portion 10c, and the pan side portion 10b of the pan 10, heating unevenness can be suppressed by performing more three-dimensional heating.

由於線圈150彼此不接觸，因此線圈150之間不導熱。由此，通過各線圈150能夠加熱鍋10的對應部分。另外，由於線圈150彼此不重疊，因此能夠固定來自各線圈150的感應加熱量。換言之，若存在線圈150彼此重疊的部分，則在重疊的部分中到鍋10的距離根據線圈150而不同，感應加熱量有可能不固定，但線圈150防止了這個問題。Since the coils 150 are not in contact with each other, there is no heat conduction between the coils 150 . Thereby, the corresponding part of the pot 10 can be heated by each coil 150 . In addition, since the coils 150 do not overlap each other, the amount of induction heating from each coil 150 can be fixed. In other words, if there is a portion where the coils 150 overlap each other, the distance to the pan 10 in the overlapped portion varies depending on the coil 150, and the amount of induction heating may not be constant, but the coil 150 prevents this problem.

線圈150間的間隙為10mm以上，通過該間隙對配置各線圈150的區域進行分區。由此，通過各線圈150能夠加熱鍋10的對應部分。另外，線圈150間的間隙為50mm以下，減少非加熱區域從而能夠均勻地加熱。The gap between the coils 150 is 10 mm or more, and the region where each coil 150 is arranged is divided by the gap. Thereby, the corresponding part of the pot 10 can be heated by each coil 150 . In addition, the gap between the coils 150 is 50 mm or less, so that the non-heating area can be reduced and uniform heating can be achieved.

通過在鍋容置部131的曲部131c安裝線圈150，能夠積極地加熱曲部131c，因此能夠實現立體的加熱。特別是，由於線圈安裝部131e為沿線圈150的內部形狀的圓弧狀，因此能夠準確定位並安裝線圈150。By attaching the coil 150 to the curved portion 131c of the pan accommodating portion 131, the curved portion 131c can be actively heated, so that three-dimensional heating can be realized. In particular, since the coil attachment portion 131e has an arc shape along the inner shape of the coil 150, the coil 150 can be accurately positioned and attached.
