(Embodiment 1)
FIG. 1 is a sectional view of a cooking utensil for a high-frequency heating device according to Embodiment 1 of the present invention, and FIG. 2 is a plan view when the cooking utensil for the high-frequency heating device is opened.

  In FIG. 1, FIG. 2, the lower container 1 and the upper container 7 of the cooking appliance for high frequency heating apparatuses are connected so that opening and closing is possible. The lower container 1 is formed of a material that transmits microwaves (for example, polypropylene resin). A lower inner member 2 is fitted inside the lower container 1. The lower inner member 2 is formed of a material that transmits microwaves (for example, polypropylene resin), and has four concave portions 3 a, 3 b, 3 c, 3 d, one central convex portion 4, and a rib shape around the convex portion 4. Protrusions 5a, 5b, 5c and 5d are provided. A space 6 is provided below the convex portion 4. Reference numeral 7 denotes an upper container of the cooking utensil for the high-frequency heating device, which is formed of a material that transmits microwaves (for example, polypropylene resin).

  An upper inner member 8 is fitted inside the upper container 7. The upper inner member 8 is formed of a material that transmits microwaves (for example, polypropylene resin), and is provided with a flat surface portion 9, and a rib 10 and a space 11 for improving strength are provided on the inner side of the upper inner member 8. ing. Reference numeral 12 denotes a hinge portion between the lower container 1 and the upper container 7. A claw portion 13 (upper container 7 side) and a flange portion 14 (lower container 1 side) are provided on the opposite side of the hinge portion 12. Reference numeral 15 is a food, and 16 is a bag containing the food 15. In the plan view of FIG. 2, only the bag 16 is shown by a dotted line, and the food material 15 is omitted from the drawing for clarifying the internal state.

  About the cooking utensil for high frequency heating devices comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the food 15 contained in the bag 16 is attached to the cooking utensil for the high-frequency heating device with the center of the food 15 contained in the bag 16 placed on the convex portion 4 at the center of the lower container 1 in the opened state as shown in FIG. Put together (as indicated by the dotted line indicating the bag 16), and then overlap the lower container 1 and the upper container 7 so that the claw portion 13 of the upper container 7 is hooked on the flange portion 14 of the lower container 1, and The foodstuff 15 containing the bag 16 is sandwiched between the portions 9 and the foodstuff 15 containing the bag 16 is sandwiched.

  Next, the cooking utensil for the high-frequency heating device is heated by a high-frequency heating device (for example, a microwave oven). Before the explanation, the heating of the general food 15 in the bag 16 by the high-frequency heating device is illustrated. 3 to explain.

  Reference numeral 17 denotes a high-frequency heating device including a microwave oven, which can place a cooked food in the cooking cabinet 18 and heat it by microwaves. As shown in FIG. 3, when the food 15 containing the bag 16 is microwave-heated, steam 19 generated when the food 15 is heated accumulates in the bag 16, but as shown in FIG. 3, the bag 16 swells upward, Hot steam 19 will accumulate at the top of the bag 16.

  However, since the hot steam 19 is separated from the food 15, the hot steam 19 does not work effectively to warm the food 15, and as a result, there is a problem that the heating time for raising the food 15 to a predetermined temperature becomes long. Moreover, the foodstuff 15 is put in the cooking chamber 18 through the bag 16, and the heat of the foodstuff 15 escapes to the cooking cabinet 18 side as shown by the arrow A through the bag 16, and this also increases the heating time. It will be.

  In contrast, in the present embodiment, as shown in FIG. 4, the cooking utensil for the high-frequency heating device to which the food 15 in the bag 16 is attached is installed in the cooking chamber 18 of the high-frequency heating device 17, and microwave heating is performed. To do. At this time, steam 19 generated from the food material 15 accumulates in the bag 16 when microwaved, but the upper portion of the bag 16 is suppressed by the flat portion 9 of the upper inner member 8 as shown in FIG. The bag 16 swells toward the recesses 3 a, 3 b, 3 c, and 3 d, and the hot steam 19 accumulates in the upper part in the vicinity of the food 15.

  Therefore, the hot steam 19 touches the food 15 and works effectively to warm the food 15. As a result, the heating time when raising the foodstuff 15 to a predetermined temperature can be shortened. The food 15 is mainly supported by the convex part 4, but there is a space 6 below the convex part 4, and the space 6 insulates the heat of the food 15, so that the outer side of the lower container 1 is directed to the outer side. Thermal radiation can be reduced, and the heating time can also be shortened by this action. Further, the swelling of the bag 16 during heating generates a force that separates the upper container 7 and the lower container 1, but the upper container 7 and the lower container 1 are coupled by the hinge part 12, the claw part 13, and the flange part 14. Can be maintained in a fixed state.

  In the present embodiment, the following three effects are exhibited by adopting a configuration in which the lower inner member 2 is fitted inside the lower container 1 and the upper inner member 8 is fitted inside the upper container 7. become.

  (1) The effect of suppressing the upward bulging of the bag 16 during microwave heating is most effective in the height dimension of the food material 15 and the convex portion 4 on the lower container 1 side and the plane on the upper container 7 side. This is the time when the space dimensions with the portion 9 are the same. Therefore, when the height dimension of the food material 15 changes greatly, it is necessary to change the space dimension of the convex part 4 and the plane part 9, but in this Embodiment, the lower inner member 2 or the upper inner member 8 is made higher than the food material 15 height. It can be adjusted easily, so it is very convenient to use.

  (2) Due to the fitting configuration, a space 6 is formed between the lower container 1 and the lower inner member 2, and a space 11 is formed between the upper container 7 and the upper inner member 8. It is possible to insulate the heat radiation from the foodstuff 15 and shorten the heating time or keep the completed state warm.

  (3) The food material 15 is heated to a high temperature, and the internal parts that come into contact with the food material 15 preferably have a structure that increases heat resistance to prevent thermal deformation. However, in this embodiment, the lower inner member is adapted to the temperature rise state of the food material 15. 2 and only the upper inner member 8 are changed to a heat-resistant material (for example, in this embodiment, polypropylene resin is used, but it is changed to a heat-resistant resin such as PBT resin). Can do.

  First, the food material 15 containing the bag 16 is sandwiched between the convex portion 4 and the rib-shaped convex portions 5a, 5b, 5c, and 5d of the lower inner member 2 and the flat portion 9 of the upper inner member 8. When the food material 15 is heated by the microwave emitted from the high-frequency heating device, the generated water vapor 19 accumulates in the bag 16 and the bag 16 expands. At this time, the bulge is pressed by the flat surface portion 9 made of the rigid body portion of the upper inner member 8, so that it enters the flexible portion 20 of the lower inner member 2.

  At this time, the hottest portion of the steam 19 accumulates in the upper portion of the bag 16, but the food 15 is formed by the convex portions 4 of the lower inner member 2 and the rigid portions of the rib-like convex portions 5 a, 5 b, 5 c, and 5 d. The hottest water vapor 19 supported and accumulated in the upper part stays in the vicinity of the food 15, and as a result, the temperature of the food 15 can be increased in a shorter time. Since this operation state is very similar to that of the first embodiment of the present invention shown in FIG. 4, the drawing is omitted.

  Further, according to the embodiment of the present invention, the food 15 contained in the bag 16 is not limited to the convex portion 4 of the lower inner member 2 and the rigid body portions of the rib-shaped convex portions 5a, 5b, 5c, and 5d, but also has a small support force but is flexible. Since the portion 20 can also be supported, the holding of the food 15 is stable, the positional relationship between the food 15 and the hottest portion of the steam 19 is always constant, and variations in the quality of the food 15 after heating are reduced.

(Embodiment 3)
6 is a cross-sectional view of the cooking utensil for the high-frequency heating device according to Embodiment 3 of the present invention, and FIG. 7 is a plan view when the cooking utensil for the high-frequency heating device is opened.

  In FIG. 6, reference numeral 21 denotes a lower inner member that is fitted inside the lower container 1. The lower inner member 21 is formed of a material that transmits microwaves (for example, polypropylene resin), and has four concave portions 22a, 22b, 22c, and 22d, one central convex portion 23, and a rib shape around the convex portion 23. Protrusions 24a, 24b, 24c, and 24d are provided. A space 25 is provided below the convex portion 23.

  Reference numeral 26 denotes a heating element that generates heat by absorbing microwaves. For example, a ferrite powder is used as a heating material, and is formed of a mixture with silicon rubber. Furthermore, the Curie point of the heating element 26 is set to about 100 ° C. The heating element 26 is fixed to the convex portion 23 with an adhesive or the like through a heat insulating material 27 made of silicon rubber, for example. Other component parts are given the same numbers as in the description of the first embodiment, and description thereof is omitted.

  About the cooking utensil for high frequency heating devices comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, as shown in FIG. 8, the food 15 in the bag 16 is attached to the cooking utensil for the high-frequency heating device, the cooking utensil for the high-frequency heating device is installed in the cooking cabinet 18 of the high-frequency heating device 17, and microwave heating is performed. When microwave heating is performed, the vapor 19 generated from the food material 15 accumulates in the bag 16. However, as shown in FIG. 8, the upper portion of the bag 16 is suppressed by the flat portion 9 of the upper inner member 8, and the recess 22 a of the lower inner member 21. , 22b, 22c, 22d, the bag 16 swells, and the hot steam 19 accumulates in the upper part in the vicinity of the foodstuff 15. Therefore, the hot steam 19 touches the food 15 and works effectively to warm the food 15. As a result, the heating time for raising the food material 15 to a predetermined temperature is shortened.

  However, when the food 15 is a frozen food, there is a problem that the input to the food becomes small at the initial stage of microwave heating, and as a result, the heating time becomes long. In the present embodiment, this is also solved. As will be described below.

  In general, FIG. 9 shows the relationship between the load amount of the foodstuff 15 of the high-frequency heating device 17 and the microwave heating input to the foodstuff 15. As can be seen from FIG. 9, the high-frequency heating device has a characteristic that the microwave heating input to the food material 15 decreases when the load amount of the food material 15 is small. In the frozen food material, the food material 15 is frozen at the initial stage of heating, and the load is reduced.

This is because ice has a smaller dielectric constant and smaller dielectric loss angle than water, and as a result, ice is about 2000 times more resistant to microwave heating than water. In order to solve this problem, in the embodiment of the present invention, a heating element 26 that absorbs microwaves and generates heat is provided in a cooking utensil for a high-frequency heating device, and as shown in FIG. A heating element 26 is provided.

  Therefore, as shown in FIG. 10, in the initial stage of heating, the amount of heating directly by the microwave acting on the food material 15 and the two types of heating in which the heating element 26 is once heated by the microwave and conducted to the food material 15. Is the sum of As described above, the microwave heating input can be increased even when the load amount is small because the food 15 in the initial stage of heating is frozen, and as a result, the heating time can be shortened.

  In addition, when the food material 15 is heated to a certain extent and thaws, and the ice becomes moisture, the load on the food material 15 increases, and the amount of direct microwave heating to the food material 15 itself increases, so the microwave to the heating element 26 is increased. Heating is not necessary. Rather, at this time, the heating efficiency is improved when the heating element 26 does not receive the microwave heating input and the food 15 receives the microwave heating input.

  In the present embodiment, a ferrite material having a Curie point of about 100 ° C. is used for the heating element 26, and therefore, when the temperature of the heating element 26 exceeds the Curie point (about 100 ° C.), The amount of wave heating will be reduced. With this action, in the initial stage of heating when the food 15 is in a frozen state, the temperature of the heating element 26 is low, the heating element 26 is heated by microwaves, and the heat is transmitted to the food 15 to promote heating. When the temperature of the material 15 rises, the ice in the food material 15 melts and changes to moisture, and the food material 15 itself is easily heated by microwaves.

  When the temperature of the heating element 26 rises and the temperature of the heating element 26 exceeds the Curie point (100 ° C.), microwave heating to the heating element 26 is reduced. Thereby, the heating element 26 is not heated unnecessarily. As a result, the heating efficiency of the food material 15 is improved by this action, and the heating time of the food material 15 can be reduced.

  Furthermore, although the foodstuff 15 is mainly supported by the heat generating body 26 on the convex portion 23, there is a space 25 below the convex portion 23, and the heat of the foodstuff 15 and the heat generating body 26 is blocked by the heat insulating material 27. In addition, the space 25 further insulates, and heat radiation to the outer side of the lower container 1 can be reduced, and this action also shortens the heating time.

  In addition, the portion of the food material 15 where the temperature is most difficult to rise is a portion at the lower central position 28 of the food material 15. In the present embodiment, the heating element 26 is provided at that portion, so that this problem can be solved. it can.

  Furthermore, when the temperature of the Curie point of the heating element 26 is 100 ° C., and the heating element 26 rises to near 100 ° C., the input of microwave heating to the heating element 26 is reduced, and the food 15 may be overheated and burnt. No. Further, for example, the bag 16 using a PET resin (heat resistant about 140 ° C.) is not thermally damaged.

  In the present embodiment, after heating the food 16 in the bag 16 once, the heating element 26 itself has a temperature near 100 ° C., and this heat storage action continues the second and subsequent foods in the bag 16. When 15 is heated, the second and subsequent heating times can be made shorter than the first time.

In this embodiment, a ferrite material is used for the heating element 26, and a material having a Curie point temperature of 100 ° C. is used. However, the heating element 26 can be anything that is heated by microwave heating. Also, the Curie point temperature may be other than 100 ° C. In short, an optimum product may be selected according to the cooking contents of the food material 15, the heat resistant temperature of the bag 16, and the microwave heating control method.

  In the first to third embodiments, the lower container 1 and the lower inner members 2 and 21 are configured as separate members, and the upper container 7 and the upper inner member 8 are configured as separate members. In short, the concave portions 3a and 22a and the convex portions 4 and 23 and the like may be formed on the lower container 1 side, and the flat portion 9 may be formed on the upper container 7 side.

  Further, in the first to third embodiments, the lower container 1 and the upper container 7 are fixed by connecting the hinge part 12 and the claw part 13 and the flange part 14. The lower container may be fixed by the weight of the upper container or the like. In short, the food material 15 in the bag 16 may be sandwiched.

  As described above, since the cooking utensil for a high-frequency heating device according to the present invention can quickly heat a packaged food using a high-frequency heating device, the heating process at the time of manufacturing the bagged food, etc. It can also be used for heating in factories.
