And a screw insertion portion formed on the other end side of each heat insulating member, and is configured to be fastened and fixed with screws inserted from the screw insertion portion into the screw fixing portion.

  Since the heat insulating members are fastened and fixed with screws, there is no possibility that the heat insulating members are easily detached by an inadvertent operation, and the safety is excellent. In addition, the replacement work when replacing some of the deteriorated heat insulating members is relatively easy.

  In the sixth feature configuration, as described in claim 6, in addition to any of the first to fifth feature configurations described above, the heat insulating member includes a pair of symmetrically supporting portions. The heating container is arranged so as to be sandwiched from the left and right sides.

  The heat insulating member can be configured with the minimum number of parts, and the loading / unloading operation when mounting or dismounting from the heating container is easy. Furthermore, each heat insulation member to comprise should just be the same shape, and suppression of manufacturing cost is possible.

Below, an example of the heating container, the heating container holder, and the heating cooking device which comprise this invention is demonstrated based on drawing.
As shown in FIGS. 1 (a) to 1 (c) and FIGS. 2 (a) and 2 (b), a heating cooker 1 includes a metal heating container 2 formed in a pan shape or a dish shape, and a heating purpose. A resin heating container holder 9 arranged so as to surround the container 2 and a metal lid body 23 are also provided.

  The heating cooker 1 is a cooker used to heat the cooking material charged in the heating container 2 using a microwave oven or an IH cooking heater, and the back surface of the bottom 2A of the heating container 2 has a thickness. A disk-shaped heating element 5 of about several mm is fixed, and heat generated by the heating element 5 is transmitted through the metal heating container 2 to heat the cooking material inside.

  The heating element 5 functions as a heating cooker 1 for a microwave oven by configuring it with a dielectric heating heating element, and functions as the heating cooking apparatus 1 for an IH cooking heater by configuring the heating element 5 with an induction heating heating element. To do.

  The heating container 2 includes an opening 3 for feeding the cooking material, and a housing 4 for housing the cooking material charged from the opening 3, and the inner edge of the opening 3 including the housing 4 and the lid 23 are flat. It is configured as a perfect circle when viewed. Although the heating container 2 and the lid 23 are made of aluminum which is excellent in thermal conductivity and is made of a lightweight material, they may be made of other metals such as copper having the same thermal conductivity characteristics.

  As shown in FIGS. 3A to 3D and FIGS. 4A to 4C, the heating container 2 includes an edge 7 slightly extending from the opening 3 outward in the radial direction of the opening 3. An extension portion 6 including a protruding piece portion 8 that extends greatly outward in the radial direction from the edge portion 7 is formed integrally with the housing portion 4.

  The edge portion 7 and the protruding piece portion 8 are formed point-symmetrically in pairs so that the edge portions 7 and the protruding piece portions 8 face each other at an interval on the outer periphery of the opening 3. The outer peripheral part of the piece part 8 is formed concentrically. Therefore, the length from the center of the opening 3 to the outer periphery of the protruding piece 8 is constant. Furthermore, the inner peripheral part of the edge part 7 and the inner peripheral part of the protrusion piece part 8 are formed in the same length.

  As shown in FIGS. 1 (a) to 1 (c) and FIGS. 2 (a) and 2 (b), the heating container holder 9 includes a heat insulating member 10 having a support portion 11 and a protection portion 12. A support 11 is provided so as to surround the opening 3 of the heating container 2 in order to support the heating container 2 without touching the high-temperature heating container 2 in a heated state with fingers or palms.

  The holding part 4 of the heating container 2 prevents the fingers, arms, etc. from touching the outer surface of the holding part 4 of the heating container 2, that is, the side wall when the support part 11 is gripped with fingers or held by the palm. A protection portion 12 is formed integrally with the support portion 11 so as to continue downward from the support portion 11 so as to hang down to the vicinity of the bottom portion 2A along the outer surface of the support portion 11.

  Heat insulation member 10 such as polytetrafluoroethylene (PTFE Teflon (registered trademark)) having a heat resistant temperature of 260 ° C., a silicon resin having a heat resistant temperature of 300 ° C., and a syndiotactic polystyrene resin (SPS) having a heat resistant temperature of 270 ° C. A resin having a high temperature can be suitably used.

  All of these resins have a low dielectric constant and excellent microwave transmission characteristics, so that they are excellent as heating container holders 9 for microwave ovens, and are difficult to deteriorate even in environments where high-temperature heating is repeated as cooking utensils. Demonstrate the heat insulation effect.

  The support portion 11 is formed to extend outward in the radial direction of the opening portion 3 so as to surround at least the extension portion 6 formed in the opening portion 3 of the heating container 2. Is formed so as to protrude outward in the radial direction from the protective portion 12 along the line. Further, the support portion 11 is formed with a protruding portion 17 that protrudes upward along the outer periphery of the support portion 11.

  As shown in FIGS. 5 (a) to 5 (c) and FIGS. 6 (a) and 6 (b), the heating container holder 9 is connected to a pair of heat insulating members 10 separable from each other and the heat insulating members 10 connected to each other. And a heat insulating support portion 11 that can support the heating container 2 by surrounding the heating container 2 in a state of being connected to each other by the connecting portion 14.

  Each heat insulating member 10 is formed in a bilaterally symmetric shape in a plan view, and is disposed so as to sandwich the heating container 2 from the left and right sides by a pair of support portions 11, and in a state of being connected by a connecting portion 14, a perfect circle in a plan view It arrange | positions concentrically with the container 2 for a heating so that it may become a shape.

  Each heat insulating member 10 is a concave portion that engages with a convex portion, that is, an extended portion 6 (7, 8) formed on the heating container 2 (see FIG. 2A, hereinafter, “convex portion” is also denoted by reference numeral 6). 13, the pair of heat insulating members 10 can be connected to each other by the connecting portion 14 in a state where the concave portion 13 is engaged with the convex portion 6.

  Grooves that function as recesses 13 from the inner peripheral side to the outer peripheral side of each heat insulating member 10 (hereinafter referred to as “grooves” are also denoted by reference numeral 13) so as to be fitted around the convex parts 6 formed along the peripheral part of the heating container 2 Is shown).

  The groove 13 includes a pair of first ribs 18 that regulate the vertical position of the edge 7 of the heating container 2, and a pair of second ribs 19 that regulate the horizontal position of the protruding piece 8 of the heating container 2, A pair of third ribs 20 that regulate the vertical position of the protruding piece 8 are provided.

  The first rib 18 protrudes from the lower surface of the groove 13 toward the upper surface, the second rib 19 extends from the lower surface of the groove 13 to the upper surface, and the third rib 20 protrudes from the lower surface of the groove 13 toward the upper surface. Is formed.

  The protruding piece portion 8 of the heating container 2 is fitted into a region guided by the pair of second ribs 19 in the groove portion 13. At that time, the vertical position of the protruding piece portion 8 is regulated by the third rib 20 and the horizontal position of the protruding piece portion 8 is regulated by the second rib 19, and the protruding piece portion 8 is completely fitted in the groove portion 13. The vertical position of the edge portion 7 of the heating container 2 is regulated by the first rib 18 in the inserted state.

  Thus, the edge 7 of the extension 6 (7, 8) formed in the heating container 2 is shallowly engaged with the groove 13, and the protrusion is formed to extend further radially outward from the edge 7. The piece 8 is deeply engaged with the groove 13 and the connecting portions 14 come into contact with each other.

  Since a gap functioning as a heat insulating layer by air is formed between the extension portion 6 formed in the heating container 2 and the support portion 11 by the first rib 18 and the third rib 20, heat transmitted to the fingers Can be further reduced.

  The connecting portion 14 includes a screw fixing portion 15 formed on one end side of each heat insulating member 10 and a screw insertion portion 16 formed on the other end side of each heat insulating member 10, and from the screw insertion portion 16 to the screw fixing portion 15. Both are fastened and fixed by the inserted screw 22.

  Although it is preferable to use the screw 22 made of the same material as the heat insulating member 10, a resin screw having a heat insulating property comparable to that of the heat insulating member 10 may be used, or a ceramic screw may be used. Assuming that the screw is heated to a temperature higher than the heat-resistant temperature of the heat insulating member 10, it is preferable to avoid the use of a metal screw because the connecting portion 14 may be softened and the tightened state may be loosened.

  Since the convex portion 6 formed in the heating container 2 and the concave portion 13 formed in the heat insulating member 10 can only be connected by the connecting portion 14 in a state where the convex portion 6 is securely engaged, the heating container holder 9 is heated. It is not attached to the container 2 in an insufficient state, and sufficient safety can be ensured. That is, there is no possibility that the heating container holder 9 is accidentally detached from the heating container 2 during cooking and an accident such as a burn occurs.

  In addition, since the heat insulating members 10 are fastened and fixed by screws 22, they are not easily detached by an inadvertent operation, and are excellent in safety. The heat insulating member 10 can be detached from the container 2 and cleaned, and the sanitary condition of the cooking utensil can be kept good.

  Furthermore, even when the heating container holder 9 deteriorates due to repeated use, only the support portion 11 can be replaced by reusing the heating container 2. Moreover, the heating container holder 9 that can be attached to or detached from the heating container 2 can be configured with a minimum number of parts at low cost.

  The convex portion 6 formed along the peripheral portion of the heating container 2 can be surely shifted to the engaged state by simply inserting the convex portion 6 into the groove portion 13 of the heat insulating member 10, and heating without fear of causing a burn. The heating cooker 1 can be contacted and supported further from any direction around 360 ° around the container 2 for heating.

  As shown in FIG. 6B, a gap G is formed between the housing portion 4 and the protection portion 12 of the heating container 2 with the heating container holder 9 attached to the heating container 2. In addition, a rib 21 that is divided into a single piece or a plurality of pieces is formed on the inner surface of the protection portion 12.

  Since the heat insulation layer by air is formed by the gap G between the protection part 12 and the outer surface of the housing part 4, the heat insulation member 10 can be kept at a lower temperature, and when the cooking device 1 for heating after the heat treatment is handled. Safety is improved.

  Further, even when food is sandwiched in the gap G between the heat insulating member 10 and the heating container 2, it can be easily removed by washing water and can be drained easily, so that it is hygienic. Note that the rib 21 may not be provided as long as it has a certain degree of strength, such as when the thickness of the protective portion 12 is sufficient.

  The protection unit 12 may be formed of a heat insulating plate-like body having a gap so that a fine mesh-shaped or ultra-fine striped finger cannot enter.

  If the surface of the protection part 12 is embossed, the cooking device 1 for heating does not easily slide down from the hand even when the protection part 12 is supported with both hands.

  As shown in FIGS. 7A to 7C, the lid body 23 includes a lid body 24 and a resin handle 25 for heat insulation. The lid body 24 is press-molded so that a concave portion 28 is formed at the center of a disk-shaped aluminum plate and a skirt portion 26 that hangs down around the periphery. A handle 25 is fitted in the recess 28 and is detachably fixed with a bolt. The lid body 24 is formed with a plurality of small-diameter vent holes 27 for releasing steam generated in the heating container 2 during cooking.

  When the heating cooker 1 described above is configured as a microwave heating cooker, a dielectric heating heating element such as a magnetic powder-containing sintered body or a magnetic powder kneaded resin molded body can be used as the heating element 5. For example, a magnetic powder-containing sintered body obtained by sintering Mg-based ferrite powder or a magnetic powder-kneaded resin molded body obtained by kneading Mg-based ferrite powder in a silicon resin can be suitably used.

  FIG. 10 shows an example of a temperature rise characteristic by microwave of a sintered body containing magnetic powder obtained by sintering Mg-based ferrite powder. Although depending on the power of the microwave, the temperature is raised to about 250 ° C. in about 20 seconds by applying the microwave, and the temperature is raised to about 270 to 280 ° C. after about 30 seconds.

  As shown in FIG. 2 (b), when the cooking device 1 for heating is used in a microwave oven, there is a risk that electric discharge may occur due to a gap between the edge of the opening 3 of the heating container 2 and the skirt portion 26 of the lid 23. There is. Therefore, in order to avoid discharge in the gap, a non-metallic heat insulation that covers at least the peripheral portion of the opening 3 of the heating container 2 and also functions as a packing interposed between the heating container 2 and the lid 23. A member 30 is disposed.

  As the heat insulating member 30, a ring-shaped member formed of flexible silicon resin is preferably used. Even when the thickness of the ring-shaped member is adjusted so that the upper surface of the ring-shaped member is located slightly below the upper surface position of the support portion 11, and the lid 23 is lifted by the pressure of steam generated during heating, the lid 23 is The movement is restricted by the inner edge of the support portion 11 so as not to move over the support portion 11.

  The specific shape of the ring-shaped member is not limited to the shape shown in FIG. 2B, and is a shape including a position restricting portion 31 that regulates the position of the lid body 23 by the shape of the ring-shaped member itself. Also good.

  As shown in FIG. 8C, the heat insulating member 30 is configured by a ring-shaped member having a L-shaped cross section, and a flat portion 30A that receives the skirt portion 26 of the lid 23, and an outer peripheral portion of the flat portion 30A. And a rising portion 31A that functions as a position restricting portion 31 that restricts the movement of the rising lid body 23 vertically. That is, the position restricting portion 31 is formed at a position facing the outer peripheral portion of the lid body 23 in the heat insulating member 30.

  As shown in FIGS. 8A and 8B, the heat insulating member 30 is preferably formed integrally with the heating container holder 9. FIG. 8A shows an example in which the position restricting portion 31 is formed integrally with the support portion 10 and is composed of a hanging wall 31B that hangs from the radially outer side of the opening 3 toward the opening 3. Yes. FIG. 8B shows an example in which the position restricting portion 31 is formed integrally with the support portion 10 and is constituted by a raised wall 31 </ b> C that protrudes from the opening 3 toward the radially outer side of the opening 3. Yes.

  As described above, since the heating cooker 1 and the heating container holder 9 are concentrically formed in a perfect circle, the heating cooker 1 is inside a microwave oven with a limited volume. Since it can be supported from any position in the surroundings without being burned, positioning and handling can be easily performed in the warehouse, and a sufficient area of the accommodating portion 4 can be secured in plan view.

  Moreover, when the support part 11 is arrange | positioned so that the opening part 3 of the container 2 for heating may be enclosed, the heating container in which the cooking material was accommodated and the gravity center moved below the opening part 3 can be supported with a stable attitude | position. It becomes like this, A finger | toe can be latched to the protrusion part 17 formed upwardly along the outer periphery of the support part 11, and the cooking device 1 for heating can be easily pulled out to the near side in the store | warehouse | chamber of a microwave oven. It is possible to avoid sliding down even when the support portion 11 is gripped.

  Further, since the edge 7 and the projecting piece 8 that fit into the groove 13 formed in the heat insulating member 10 are formed on the outer periphery of the opening 3 with a space therebetween, the support 11 is supported by fingers. However, the weights of the heating container 2 and the cooking material are not received only by the resin support 11, but are sufficiently received by the edge 7 and the projecting piece 8.

  In consideration of the strength of the support portion 11, when only the edge portion 7 having a short extension length is disposed on the entire circumference of the opening portion 3, the extension length of the support portion 11 is also shortened, and the cooking device 1 for heating is supported. Although it becomes difficult, the extended length of the support portion 11 can be sufficiently secured by providing the projecting piece portion 8 having a long extended length, and it becomes easy to support the cooking device 1 for heating, and the entire circumference of the opening portion 3. Therefore, it is not necessary to arrange the projecting piece 8 on the surface, so that the material cost can be reduced.

  Further, since the outer peripheral portion of the edge portion 7 and the outer peripheral portion of the projecting piece portion 8 are formed concentrically, it can be efficiently pressed without causing waste of materials, and the microwave oven of the heating container 2 It is also easy to confirm the position of the accommodating portion 4 in the storage. Furthermore, since the length from the center of the opening 3 to the outer periphery of the projecting piece 8 is constant and concentric with the housing 4, while being limited by the size of the microwave oven, It is possible to configure so as to ensure a sufficient area of the accommodating portion 4 in plan view.

Hereinafter, another embodiment of the present invention will be described.

  In the embodiment described above, the first rib 18 and the third rib 20 that regulate the vertical position of the extending portion 6 project from the lower surface of the groove portion 13 to the upper surface of the groove portion 13 formed in the heating container holder 9. Although the formed example was demonstrated, the 1st rib 18 and the 3rd rib 20 may be protruded and formed in the lower surface from the upper surface of the said groove part 13. As shown in FIG.

  9A and 9B show an example in which the third rib 20 is formed to protrude from the upper surface of the groove 13 to the lower surface. In this case, the extending portion 6 of the heating container 2 can be stably received without separating the space on the lower surface of the support portion 11.

  Further, as shown in FIG. 9A, when the first rib 18 and the third rib 20 are formed so as to protrude from the upper surface of the groove portion 13 to the lower surface, the first rib 18 and the third rib 20 depend from the upper surface of the support portion 11 toward the opening portion 3. The position restricting portion 31 for restricting the movement of the lid body 23 can be constituted by the suspended wall 31B, and the skirt portion 26 of the lid body 23 is received by the flat portion 30A extending in the horizontal direction from the hanging wall 31B. It is possible to avoid the occurrence of a spark between the heater 23 and the heating container 2.

  In embodiment mentioned above, although the convex part 6 inserted in the groove part 13 formed in the container holder 9 for heating was demonstrated continuously in the outer periphery of the opening part 3 of the container 2 for heating, the convex part was demonstrated. 6 may be formed on the outer periphery of the opening 3 of the heating container 2 at intervals. Similarly, the groove part 13 formed in the container holder 9 for heating may be intermittently formed corresponding to each convex part 6.

  In the embodiment described above, an example in which a pair of the edge portion 7 and the projecting piece portion 8 that fit into the groove portion 13 formed in the heat insulating member 10 is formed on the outer periphery of the opening portion 3 with an interval therebetween is described. The edge part 7 and the protrusion piece part 8 may be formed one by one. Each of the first rib 18 to the third rib 20 only needs to be formed in the groove 13 formed in the heating container holder 9 corresponding to them.
