Description

  The present invention relates to a thawing heating auxiliary member used when thawing and heating frozen foods such as frozen rice cake and frozen sushi in a microwave oven.

Lunch boxes that have been commercially available at convenience stores and the like are displayed at the store in a cold state, heated in a cash register at a cash register, and delivered to customers in a warm state. Of course, lunch boxes have a best-before date, and lunch boxes that have expired are discarded. It is an urgent task to reduce the amount of lunches to be disposed of from the viewpoint of environmental protection as well as dealers.
JP-A-9-98888

  In view of this, it is conceivable to display frozen lunches at the store and to defrost and heat them at a cash register. According to this method, the expiration date (preservation date) of bento can be greatly extended. For this reason, the amount of lunch to be disposed of can be reduced.

  However, it is difficult to thaw frozen foods and heat them to a temperature suitable for eating. For example, in the case of frozen rice bran, the moisture content of the ingredients is often greater than the moisture content of rice. For this reason, when thawing heating is performed on the basis of the ingredient, that is, when the heating is stopped in a state where the ingredient is at a temperature suitable for eating, an unthawed portion or a cold portion may remain in the rice. On the other hand, when thawing heating is performed based on rice, that is, when heating is stopped at a temperature suitable for eating, the ingredients may be heated excessively and quality (flavor, texture, etc.) may be impaired.

  In this regard, Patent Document 1 introduces a thawing heating jig including a mounting table, an intermediate layer, and a bottom plate. The mounting table is made of a dielectric material. The intermediate layer is disposed below the mounting table. The intermediate layer is an air layer. The bottom plate is disposed below the intermediate layer. The bottom plate is made of a conductive material. The bottom plate, that is, the thawing heating jig is mounted on the top surface of the turntable.

  The frozen jar placed on the mounting table is heated by the microwaves irradiated from above. In addition, the freezer is heated from below by a microwave surface wave formed near the top surface of the mounting table. In addition, the freezer is heated from below by the microwaves reflected from the lower surface of the mounting table and the upper surface of the bottom plate. For this reason, the heating efficiency of the lower part of the freezer is higher than the heating efficiency of the upper part. Therefore, the rice of the frozen rice cake is warmed in preference to the ingredients placed on the rice.

  However, the electric field intensity of the surface wave formed in the vicinity of the upper surface of the mounting table decreases as it goes upward. In addition, the freezing basket absorbs microwaves not only from the lower surface (bottom surface) but also from the upper surface or side surfaces. For this reason, it is difficult to significantly increase the heating efficiency of the lower part of the freezer compared with the heating efficiency of the upper part.

  Microwaves are irradiated from above the freezer. For this reason, the refrigeration bowl inevitably absorbs microwaves unavoidably. Therefore, the quality of the tool may be impaired by the absorbed microwave. For example, when the frozen salmon is seafood salmon, it is preferable that the temperature of the seafood (raw food) as a tool is low. However, when the tool is directly irradiated with microwaves, the tool may become warm. Also, only the vicinity of the upper surface of the tool may lose moisture and become crispy.

  The thawing heating auxiliary member of the present invention has been completed in view of the above problems. Therefore, an object of the present invention is to provide a thawing heating auxiliary member that can locally increase the heating efficiency of the lower portion of the frozen food and has a low risk of impairing the quality of the upper portion of the frozen food.

  (1) In order to solve the above-described problem, the defrosting heating auxiliary member of the present invention is disposed in a thawing heating chamber of a microwave oven and has a microwave breaker that can cut off the microwave supplied to the thawing heating chamber. It is a heating auxiliary member, and the microwave breaker penetrates itself in the vertical direction and has an arrangement hole in which the frozen food is arranged on the inner peripheral side, and is a lower part than the arrangement hole in the frozen food Is characterized in that the microwave is directly irradiated, and the microwave is indirectly irradiated to a portion above the arrangement hole in the frozen food through the arrangement hole.

  In this specification, “directly irradiating” the lower part of the frozen food means that the microwave supplied to the thawing heating chamber is reflected directly or within the thawing heating chamber, for example, inclusions such as ceramics and paper It means that the lower part of the frozen food is irradiated without passing through.

  In addition, “indirect irradiation” on the upper portion of the frozen food means that the microwave supplied to the thawing heating chamber passes through at least one of the space in the arrangement hole and the portion of the frozen food existing in the arrangement hole. It means that the upper part of the frozen food is irradiated.

  According to the thawing heating auxiliary member of the present invention, the microwave that has been conventionally directly irradiated to the upper portion of the frozen food is also directly irradiated to the lower portion. For this reason, the heating efficiency of the lower part of frozen food can be made high locally. Therefore, it is possible to heat up to the inside of the lower part more rapidly. Further, below the arrangement hole, not only the lower surface of the frozen food but also the entire surface of the lower part is exposed to the microwave. That is, microwaves are absorbed from the entire lower surface. Also in this point, according to the thawing heating auxiliary member of the present invention, the heating efficiency of the lower portion can be locally increased.

  On the other hand, the microwave is not directly irradiated to the upper part of the frozen food. The upper part is due to microwaves irradiated indirectly through the part of the frozen food in the arrangement hole or the space in the arrangement hole, heat conduction from the lower part, steam rising from the lower part, etc. Heated. For this reason, according to the thawing heating auxiliary member of the present invention, the heating efficiency of the upper part of the frozen food is low. Moreover, since microwaves are not directly absorbed from the surface of the upper portion, there is little risk of impairing the quality of the upper portion.

  Moreover, according to the thawing heating auxiliary member of the present invention, the frozen food is held by the arrangement hole. For this reason, the stability of frozen food is high. In addition, if the position of the arrangement hole in the microwave breaker is set so that the microwave tends to concentrate on the lower part of the frozen food, the frozen food can always be thawed under good thawing heating conditions. . In other words, the frozen food can be guided and positioned at a position where it can be easily thawed and heated depending on the position of the arrangement hole.

  (2) Preferably, the microwave breaker is made of metal. The microwave is reflected by the metal. For this reason, according to this structure, it can suppress that a microwave permeate | transmits a microwave blocker (except arrangement holes), and is absorbed by the upper part of frozen food. Moreover, the lower part of frozen food can be heated with the microwave reflected by the microwave interrupter.

  (3) Preferably, it is more preferable to have a microwave blocking cover that is disposed above the microwave blocking tool and covers the upper portion so as to block the microwave. According to this configuration, even if the power supply opening is opened upward in the thawing heating chamber of the microwave oven, it is possible to suppress direct microwave irradiation to the upper portion of the frozen food. Can do. In addition, the microwave can be intensively applied to the lower portion of the frozen food.

  (4) Preferably, in the above (3), the microwave blocking cover is preferably made of metal. According to this structure, it can suppress that a microwave permeate | transmits a microwave interruption | blocking cover and is absorbed by the upper part of frozen food. Moreover, the said lower part can be heated when the microwave reflected by the microwave interruption | blocking cover goes around to the lower part of frozen food.

  (5) Preferably, it is further preferable to have a configuration in which a support leg is disposed below the microwave breaker and supports the microwave breaker. According to this configuration, even when there is no member that supports the microwave breaker on the side of the thawing heating chamber of the microwave oven, the microwave breaker can be disposed in the thawing heating chamber.

  (6) Preferably, the microwave breaker is configured to partition the thawing heating chamber into two upper and lower chambers, an upper chamber and a lower chamber, and the microwave is supplied to the lower chamber. A microwave breaker isolates the upper chamber from the microwave. In addition, the lower chamber is exposed to microwaves. According to this structure, it can suppress comparatively easily that a microwave is directly irradiated to the upper part of frozen food. In addition, it is relatively easy to promote direct irradiation of microwaves on the lower portion of the frozen food.

  (7) Preferably, the microwave breaker further includes a hole diameter adjusting mechanism capable of adjusting the hole diameter of the arrangement hole. According to this structure, the hole diameter of an arrangement | positioning hole can be changed according to the outer diameter of frozen food. When the frozen food has a shape that shrinks downward, the amount of downward projection of the frozen food with respect to the microwave breaker (that is, the vertical length of the lower portion of the frozen food) and the vertical direction of the upper portion of the frozen food The length can be adjusted to the desired length.

  According to the thawing heating auxiliary member of the present invention, it is possible to locally increase the heating efficiency of the lower portion of the frozen food, and to provide a thawing heating auxiliary member that is less likely to impair the quality of the upper portion of the frozen food. it can.

  Hereinafter, embodiments of the thawing heating auxiliary member of the present invention will be described.

  <First embodiment>

  First, the structure of the defrosting heating auxiliary member of this embodiment will be described. FIG. 1 shows a perspective exploded view of a microwave oven in which the thawing heating auxiliary member of this embodiment is arranged. FIG. 2 shows a schematic cross-sectional view of the microwave oven. As shown in these drawings, the thawing heating auxiliary member 1 includes a microwave blocking table 2, a microwave blocking cover 3, and support legs 4. The microwave cutoff table 2 is included in the microwave cutoff device of the present invention. The thawing heating auxiliary member 1 is accommodated in the thawing heating chamber 90 of the microwave oven 9. The microwave oven 9 is a commercial microwave oven installed in a convenience store or the like. A power supply port 91 is opened on the upper bottom surface of the thawing heating chamber 90. The power supply port 91 communicates with the antenna of the magnetron 92. The output of the microwave oven 9 is 3 kW.

  The microwave cutoff table 2 is made of metal and has a rectangular plate shape. In the center of the microwave blocking table 2, a perfectly circular arrangement hole 20 is formed. A freezer basket 8 is arranged on the inner peripheral side of the arrangement hole 20. The frozen rice cake 8 is included in the frozen food of the present invention.

  The lower part 8 a of the freezer 8 protrudes below the arrangement hole 20. On the other hand, the upper portion 8 b of the freezer 8 protrudes above the arrangement hole 20. The frozen rice cake 8 includes a container 80, rice 81, and a tool 82. The container 80 is made of resin and has a teacup shape that is pointed downward and opened upward. The rice 81 and the ingredient 82 are both in a frozen state and are accommodated in the container 80. The ingredient 82 is placed on the upper surface of the rice 81.

  The support leg 4 is made of metal and has a round bar shape. A total of four support legs 4 are arranged. The four support legs 4 protrude downward from the four corners of the lower surface of the microwave cutoff table 2. The lower end of the support leg 4 is in contact with the lower surface of the thawing heating chamber 90.

  The microwave shielding cover 3 is made of metal and has a rectangular parallelepiped box shape opening downward. The microwave blocking cover 3 is disposed on the upper surface of the microwave blocking table 2 in a state where the opening is covered. The microwave blocking cover 3 covers the upper part 8 b of the freezer 8. A wire mesh 30 is attached to the upper wall and side wall of the microwave shielding cover 3. The mesh (interline distance) of the metal mesh 30 is set to 1 mm so that the microwave does not pass through. Engagement hooks 31 are arranged at the lower ends of the four side walls of the microwave shielding cover 3. The engagement hook 31 is made of metal and has a frame shape. The engagement hook 31 is supported so as to be rotatable around the lower end of the side wall. The front end of the engagement hook 31 is locked to the lower surface of the microwave cutoff table 2.

  Next, the movement at the time of setting the freezer 12 in the thawing heating auxiliary member 1 of this embodiment will be described. First, the freezer 8 is arranged in the arrangement hole 20 of the microwave cutoff table 2 from above. Next, the microwave shielding cover 3 is placed on the freezer 8. Then, the engaging hook 31 of the microwave blocking cover 3 is locked to the lower surface of the microwave blocking table 2. The microwave blocking cover 3 is fixed to the microwave blocking table 2 by the locking. The upper portion 8 b of the freezer 8 is surrounded by the microwave cutoff table 2 and the microwave cutoff cover 3.

  Next, the movement at the time of thawing and heating the frozen jar 8 using the thawing heating auxiliary member 1 of the present embodiment will be described. As shown in FIG. 2, the microwave generated from the magnetron 92 is supplied into the thawing heating chamber 90 through the power supply port 91. That is, the microwave is supplied to the freezer 8 from above. Here, the walls defining the thawing heating chamber 90 are made of metal. In addition, the microwave blocking cover 3 is made of metal. Further, the microwave cannot pass through the mesh of the metal mesh 30. For this reason, the supplied microwave is repeatedly reflected by the wall of the thawing heating chamber 90 or the microwave blocking cover 3, and goes around to the lower side of the thawing heating chamber 90. Below the thawing heating chamber 90, the lower surface of the microwave cutoff table 2 and the lower portion 8 a of the freezer 12 are exposed. Here, the microwave cutoff table 2 is made of metal. For this reason, the microwave that has entered the lower side of the thawing heating chamber 90 is reflected by the lower surface of the microwave blocking table 2. Finally, the microwave is absorbed from the entire surface of the lower part 8a of the freezer 8. In this way, the microwave propagated in the thawing heating chamber 90 is absorbed by the entire surface of the lower portion 8a of the freezer basket 8 that only absorbs microwaves in the thawing heating chamber 90.

  The absorbed microwaves cause the rice 81 in the lower portion 8a to be quickly thawed and warmed to a temperature suitable for eating. The microwave attenuates exponentially as it travels inside the rice 81. However, the microwave is absorbed by the entire surface of the lower portion 8a. For this reason, the center part of the rice 81 is also fully thawed and warmed to a temperature suitable for eating.

  A part of the microwaves passes through the lower part 8a and reaches the upper part 8b while being attenuated. For this reason, the upper portion 8b also absorbs microwaves and is heated. Moreover, the heat of the lower part 8a is transmitted through the rice 81 by heat conduction. The upper portion 8b is also heated by this heat conduction. Further, water vapor is generated from the lower portion 8a heated by the microwave. Steam rises in the rice 81. The upper portion 8b is also heated by this water vapor. In addition, the water vapor that has reached the upper portion 8b is changed to water, and the upper portion 8b is also heated by the water being heated by the microwave. Thus, the rice 81 and the tool 82 of the upper part 8b are heated from below by indirect microwaves, heat conduction, water vapor, and the like. It is then thawed and warmed to a temperature suitable for eating.

  Next, the effect of the thawing heating auxiliary member 1 of this embodiment will be described. According to the thawing heating auxiliary member 1 of the present embodiment, the microwave that has been conventionally applied directly to the upper portion 8b of the freezer 8 is also applied to the lower portion 8a. For this reason, the heating efficiency of the lower part 8a can be made higher than the heating efficiency of the upper part 8b. Therefore, it is possible to heat more rapidly to the central portion inside the lower portion 8a. Further, microwaves are absorbed into the inside of the freezer 8 not only from the lower surface of the freezer 8 but also from the entire lower surface 8a. Also in this respect, the heating efficiency of the lower portion 8a can be increased.

  On the other hand, the upper portion 8b is not directly irradiated with microwaves. The upper part 8b is heated by microwaves irradiated indirectly via the lower part 8a, heat conduction from the lower part 8a, water vapor rising from the lower part 8a, and the like. For this reason, according to the thawing heating auxiliary member 1 of the present embodiment, the heating efficiency of the upper portion 8b is low. Further, since microwaves are not directly irradiated from the surface of the tool 82, there is little risk of impairing the quality of the tool 82. Specifically, even if the tool 82 is raw, the risk of the surface becoming warm is small. Further, there is little risk that moisture will escape from the vicinity of the surface of the tool 82 and the tool 82 will become clumsy. Further, according to the thawing heating auxiliary member 1 of the present embodiment, heat moves from the rice 81 toward the ingredient 82. For this reason, it is possible to reproduce the state in which the ingredients 82 are placed on the warm rice 81 as if they were served.

  The microwave cutoff table 2 is made of metal. For this reason, it can prevent that a microwave permeate | transmits the microwave interruption | blocking table 2 (except the arrangement | positioning hole 20), and is absorbed by the upper part 8b. Further, the lower portion 8 a can be heated by the microwave reflected by the microwave blocking table 2.

  Further, the defrosting heating auxiliary member 1 of the present embodiment has a microwave blocking cover 3. For this reason, it is possible to prevent the microwave from being directly irradiated to the upper portion 8b even though the power supply port 91 is opened above the freezer 8. In addition, the lower portion 8a of the freezer 8 can be intensively irradiated with microwaves.

  The microwave blocking cover 3 is made of metal. For this reason, it can suppress that a microwave permeate | transmits the microwave interruption | blocking cover 3 and is absorbed by the upper part 8b. Moreover, the lower part 8a can be heated intensively when the microwave reflected by the microwave interruption | blocking cover 3 goes around to the lower part 8a.

  Further, the thawing heating auxiliary member 1 of the present embodiment has support legs 4. For this reason, the microwave cutoff table 2 can be disposed in the thawing heating chamber 90 even though there is no member that supports the microwave cutoff table 2 on the side of the thawing heating chamber 90 of the microwave oven 9. That is, the thawing heating auxiliary member 1 of this embodiment can be used regardless of the type of the microwave oven 9. For this reason, the defrosting heating auxiliary member 1 of this embodiment is highly versatile.

  Moreover, the defrosting heating auxiliary member 1 of this embodiment is used in a commercial microwave oven 9. For this reason, combined with the high heating efficiency and the high output, the lower portion 8a can be defrosted and heated more rapidly. On the other hand, the upper portion 8 b is surrounded by the microwave cutoff cover 3 and the microwave cutoff table 2. For this reason, although the output of the microwave oven 9 is high, there is no possibility that the upper portion 8b is excessively thawed and heated. As described above, when the thawing heating auxiliary member 1 of the present embodiment is used in the commercial microwave oven 9, the frozen basket 8 can be provided to the customer quickly and without impairing the quality.

  Further, according to the thawing heating auxiliary member 1 of the present embodiment, the microwave blocking cover 3 is fixed to the microwave blocking table 2 by the engagement hook 31. For this reason, the possibility that the microwave blocking cover 3 is detached from the microwave blocking table 2 is small. Further, there is little possibility that the microwave is irradiated to the upper portion 8b through the gap between the microwave blocking cover 3 and the microwave blocking table 2.

  Further, according to the thawing heating auxiliary member 1 of the present embodiment, the wire mesh 30 is disposed on the microwave blocking cover 3. For this reason, water vapor generated by thawing heating can be released to the outside of the microwave shielding cover 3 through the mesh. Accordingly, the water vapor is condensed on the upper bottom surface of the microwave shielding cover 3 to form water droplets, and there is little possibility that the water droplets will fall on the tool 82 of the freezer 8 after thawing heating. Also in this respect, there is little risk of impairing the quality of the tool 82.

  Further, according to the thawing heating auxiliary member 1 of the present embodiment, the microwave cut-off table 2 is directly touched to the refrigeration bowl 8 by putting the microwave block table 2 in and out of the thawing heating chamber 90 in a state where the refrigeration bowl 8 is arranged in the arrangement hole 20. The frozen basket 8 can be taken in and out of the thawing heating chamber 90 without any trouble. For this reason, it is convenient, for example, when the temperature of the freezer 12 is high. The freezer 8 is held by the arrangement hole 20. For this reason, there is little possibility that the freezer 8 will fall off the microwave cutoff table 2.

  <Second embodiment>

  The difference between the present embodiment and the first embodiment is that a microwave blocking plate that divides the thawing heating chamber into two upper and lower chambers is arranged instead of the microwave blocking table. Therefore, only the differences will be described here.

  FIG. 3 shows a schematic cross-sectional view of a microwave oven in which the thawing heating auxiliary member of this embodiment is arranged. In addition, about the site | part corresponding to FIG. 2, it shows with the same code | symbol. The microwave oven 9 is a microwave oven for home use. The output of the microwave oven 9 is 500W. On both side surfaces of the thawing heating chamber 90, two guide rails 93 for arranging oven pans (not shown) are arranged on the upper and lower sides respectively.

  The microwave blocking plate 5 is made of metal and has a rectangular plate shape as a whole. The microwave blocking plate 5 is included in the microwave blocking device of the present invention. The microwave blocking plate 5 is installed between a pair of guide rails 93 facing in the width direction. A true circular arrangement hole 50 is formed in the center of the microwave blocking plate 5. A freezer basket 8 is arranged on the inner peripheral side of the arrangement hole 50. The microwave blocking plate 5 partitions the thawing heating chamber 90 into a lower chamber 90a and an upper chamber 90b. A lower portion 8a of the freezer 8 protrudes into the lower chamber 90a. On the other hand, the upper portion 8b protrudes into the upper chamber 90b. A power supply port 91 is provided on the lower surface of the lower chamber 90a. The microwave blocking plate 5 can slide on the pair of guide rails 93. By the slide, the microwave blocking plate 5, that is, the freezer 8 can be taken in and out of the thawing heating chamber 90.

  FIG. 4 shows a perspective exploded view of the microwave blocking plate 5. As shown in the figure, the microwave blocking plate 5 includes a plate body 51 and a pair of adjusting blades 52. The plate body 51 has a flat rectangular tubular shape. The plate body 51 has a pair of openings 510 facing in the width direction. Opening side stoppers 511 are formed at the edges of the opening 510. FIG. 5 shows an enlarged view in the circle IV of FIG. As shown in FIG. 5, the opening-side stopper 511 is formed by bending a protruding piece (shown by a dotted line in the figure) formed on the plate body 51 inward.

  Returning to FIG. 4, the pair of adjusting blades 52 has a rectangular plate shape. The pair of adjusting blades 52 are respectively arranged so as to be able to be taken in and out with respect to the pair of openings 510 of the plate body 51. The horizontal width of the microwave blocking plate 5 can be adjusted by inserting and removing the adjusting blade 52 from the plate body 51. Further, the blade end of the adjustment blade 52 is locked on the guide rail 93, whereby the microwave blocking plate 5 is installed on the guide rail 93. A blade-side stopper 520 is formed at the root end of the adjustment blade 52. The wing-side stopper 520 can be engaged with the opening-side stopper 511. By engaging the blade side stopper 520 and the opening side stopper 511, the adjustment blade 52 is prevented from being separated from the plate body 51 and falling off.

  The thawing heating auxiliary member 1 of the present embodiment has the same effects as the thawing heating auxiliary member of the first embodiment. Moreover, according to the thawing heating auxiliary member 1 of the present embodiment, the lower portion 8a can be directly irradiated with microwaves relatively easily without using a microwave blocking cover, a support leg or the like. In addition, the microwave can be prevented from being directly irradiated to the upper portion 8b in a relatively simple manner.

  Further, according to the thawing heating auxiliary member 1 of the present embodiment, the horizontal width of the microwave blocking plate 5 can be adjusted by inserting and removing the adjusting blade 52 from the plate body 51. For this reason, the microwave blocking plate 5 can be disposed regardless of the width of the thawing heating chamber 90. Therefore, the defrosting heating auxiliary member 1 of the present embodiment is highly versatile.

  Moreover, according to the thawing heating auxiliary member 1 of the present embodiment, the entire output of the microwave oven 9 is used to heat the lower portion 8 a of the freezer 8. For this reason, although it is a low output household microwave oven 9, the frozen rice cake 8 can be defrosted and heated to a temperature suitable for eating. Further, according to the thawing heating auxiliary member 1 of the present embodiment, the arrangement hole 50 is arranged directly above the power supply port 91. For this reason, the heating efficiency of the lower part 8a is high.

  <Third embodiment>

  The difference between the present embodiment and the first embodiment is that a hole diameter adjusting mechanism is arranged on the microwave blocking table. Therefore, only the differences will be described here. FIG. 6 shows an exploded perspective view of the thawing heating auxiliary member of this embodiment as viewed from below the microwave blocking table and the support legs. In addition, the same code | symbol is shown about the site | part corresponding to FIG. As shown in the figure, the microwave cutoff table 2 includes a table body 21 and an adjustment plate 22. The adjusting plate 22 is included in the hole diameter adjusting mechanism of the present invention.

  The table body 21 is made of metal and has a rectangular plate shape. In the center of the table main body 21, a true circular arrangement hole main body 20a is formed. Both of the opposing long sides of the table body 21 are bent downward in a C shape. Guide portions 210 are partitioned in the C-shape.

  The adjustment plate 22 is made of metal and has a rectangular plate shape. An adjustment recess 20 b is formed on one side of the adjustment plate 22. The adjustment recess 20b has a semicircular shape. A pair of guided portions 220 are disposed on two sides of the adjustment plate 22 facing each other with the adjustment recess 20b interposed therebetween. As the guided portion 220 is guided by the guide portion 210, the adjustment plate 22 can slide in the horizontal width direction inside the table body 21.

  A case where the outer diameter of the freezer is large will be described. FIG. 7 is a schematic cross-sectional view of the microwave blocking table of the thawing heating auxiliary member of this embodiment. Parts corresponding to those in FIG. 2 are denoted by the same reference numerals. As shown in the figure, the outer diameter of the container 80 of the freezer 8 is relatively large. When the container 80 has a large diameter, the freezer 8 is held only by the arrangement hole main body 20a. In this case, the arrangement hole body 20a corresponds to the arrangement hole of the present invention.

  The case where the outer diameter of the freezer is small will be described. FIG. 8 shows a schematic cross-sectional view of the microwave cutoff table. Parts corresponding to those in FIG. 2 are denoted by the same reference numerals. As shown in the figure, the outer diameter of the container 80 of the freezer 8 is relatively small. When the container 80 has a small diameter, the adjustment plate 22 is slid toward the center in the horizontal width direction of the table body 21 from the state shown in FIG. Then, the adjustment plate 22, that is, the adjustment recess 20b is made to enter the arrangement hole main body 20a. Here, the space | interval of the arrangement | positioning hole main body 20a and adjustment recessed part 20b end which opposes a width direction is smaller than the hole diameter of arrangement | positioning hole main body 20a independent. For this reason, the small-diameter container 80, that is, the freezer 8 is sandwiched between the arrangement hole main body 20a and the adjustment recess 20b. In this case, the arrangement hole main body 20a and the adjustment recess 20b correspond to the arrangement hole of the present invention.

  A case where the ratio between the lower part and the upper part of the freezer is changed will be described. FIG. 9 shows a schematic cross-sectional view of the microwave cutoff table. Parts corresponding to those in FIG. 2 are denoted by the same reference numerals. As shown in the figure, when the ratio of the upper portion 8b is increased and the ratio of the lower portion 8a is decreased, the adjustment plate 22 is moved from the state of FIG. Slide toward the center of the direction. And the freezer 8 is clamped by the arrangement | positioning hole main body 20a and the adjustment recessed part 20b. On the other hand, when the ratio of the upper part 8b is reduced and the ratio of the lower part 8a is increased, the adjustment plate 22 is slid in the direction opposite to the above direction. And the space | interval of the arrangement | positioning hole main body 20a edge and adjustment recessed part 20b edge which opposes a horizontal width direction is enlarged.

  The thawing heating auxiliary member of this embodiment has the same function and effect as the thawing heating auxiliary member of the first embodiment. Moreover, according to the defrosting heating auxiliary member of the present embodiment, the overlapping area between the arrangement hole main body 20a and the adjustment recess 20b can be adjusted. Moreover, the space | interval of the arrangement | positioning hole main body 20a end and adjustment recessed part 20b end which opposes a horizontal width direction can be adjusted. For this reason, the hole diameter of the arrangement hole can be adjusted according to the outer diameter of the container 80 of the freezer 8. Moreover, the ratio of the lower part 8a and the upper part 8b of the freezer 8 can be adjusted. For this reason, it is easy to search for thawing heating conditions suitable for eating.

  <Others>

  The embodiment of the thawing heating auxiliary member of the present invention has been described above. However, the embodiment is not particularly limited to the above embodiment. Various modifications and improvements that can be made by those skilled in the art are also possible.

  For example, in the above-described embodiment, the thawing heating auxiliary member of the present invention is used for thawing heating of the frozen rice cake 8, but may be used for other frozen foods such as frozen sushi, frozen noodles, and frozen buns. In particular, the thawing heating auxiliary member of the present invention can be suitably used for frozen food when the upper portion has a lower proper temperature than the lower portion.

  Moreover, in the said embodiment, although the mesh of the metal mesh 30 of the microwave interruption | blocking cover 3 was 1 mm, a mesh is not specifically limited (refer above-mentioned FIG. 1). Any size that does not transmit microwaves is acceptable.
