Description

[Technical field]

[0001] The present invention relates to a microwave conditioner for use in a microwave oven and a frozen food product enclosed therewith. [Background technology]

[0002] A microwave oven is configured to have a microwave generator built into the wall of the oven chamber, and to radiate microwaves in a predetermined direction to heat an object to be heated.

[0003] In this case, there is a problem that the microwave oven has uneven heating, and the object to be heated is not heated evenly. In order to solve this problem, various devices have been developed, such as a turntable for the microwave oven stand (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 05-025201 Summary of the Invention [Problem to be solved by the invention]

[0005] However, there are still cases where the object to be heated is insufficiently heated in some places. For example, a frozen food such as gratin may be hot enough to burn you at the periphery, but cold at the center. This is due to the uneven distribution of the amount of microwaves that reach each part of the object to be heated. In particular, fixed table type ovens that are not turntable type tend to have noticeable uneven heating.

[0006] The present invention has been made with a focus on such problems, and aims to realize a microwave conditioner for a microwave oven, which efficiently heats the difficult-to-heat central portion and improves the uniformity of the overall heating, and a frozen food product enclosed with the same. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention takes the following measures.

[0008] In other words, the microwave adjustment device for a microwave oven according to the present invention is characterized in that a plate-shaped material is folded in a circular shape and the ends are engaged to form a three-dimensional structure, and the three-dimensional structure is placed on the microwave stand with a direction perpendicular to the circular direction facing up and down, thereby increasing the amount of microwaves that are reflected inside the oven and reach the center of the object to be heated.

[0009] In this case, it is preferable that the plate-like material is strip-shaped and the width dimension is set to a predetermined lifting height.

[0010] It is also preferable that the plate-shaped material has a guide for cutting or folding back along the longitudinal direction, thereby making it possible to adjust the width dimension.

[0011] The three-dimensional structure may be a cylinder or a polygonal column.

[0012] The microwave conditioner for a microwave oven is preferably used enclosed in a packaging container. Effect of the Invention

[0013] According to the present invention, it is possible to provide a microwave conditioner for a microwave oven, which efficiently heats the difficult-to-heat central portion and improves the uniformity of heating throughout, and a frozen food product enclosed therewith.

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] FIG. 1 shows a microwave adjuster A for a microwave oven according to this embodiment. As shown in FIG. 1(a), this microwave enhancer A for use in a microwave oven is formed by forming a plate-like material 1 made of a stiff material (such as cardboard) into a rectangular shape (strip) of length x and width y, with a slit 11 in the short direction near one end 1a and an insertion portion 12 that can be inserted into the slit 11 formed on the other end 1b.

[0017] One example is x=3, y=15, but of course these dimensions can be set appropriately.

[0018] The width W1 of the slit 11 is cut in a range narrower than the width W of the cardboard 1. On the other hand, the insertion part 12 has a tip 12b at the tip of the base end 12a formed in an arrow shape, the width W2 of the base end 12a is almost equal to the slit width W1, and the width W3 of the tip 12b is wider than the width W2 of the base end, forming a triangular shape.

[0019] The corner 1ab on the side of one end 1a is rounded off so that parts of it can be easily overlapped when the whole is rounded in the longitudinal direction.

[0020] Then, this plate-like material 1 is rolled in the longitudinal direction as shown in FIG. 1(b), and the insertion portion 12 is inserted into the slit 11 from the outside to the inside while gradually bending or narrowing it, and then expanded at the end of the insertion, thereby preventing it from slipping out and fashioning it into a cylindrical three-dimensional structure AA.

[0021] FIG. 2 is a schematic diagram showing a state in which the microwave conditioner A for use in a microwave oven is placed on a microwave stand b1 of a microwave oven B.

[0022] 3 shows an example of using a microwave oven B in a conventional general state without using the microwave conditioner A for a microwave oven, in which a microwave stand b1 in a heating chamber b2 is composed of a flat table or the like, and a microwave generator (not shown) is provided on a side wall b3, for example. When an object 10 to be heated is placed directly on this microwave stand b1 and heated, microwaves X are irradiated from the side wall b3 obliquely downward toward the center, so that if the center 10a of the object 10 to be heated is less easily hit by microwaves X than some peripheral portions 10b, it takes time to heat the center 10a.

[0023] In contrast, as shown in FIG. 2, when the microwave adjustment tool A for a microwave oven is placed on a microwave stand b1 constituted by a flat table or the like, the object 10 to be heated is raised and the microwaves X hit the object 10 not only from above but also from below. This shortens the heating time of the center 10a, and it has been found that the object 10 to be heated can be heated more uniformly, including the peripheral portion 10b.

[0024] As described above, the temperature after heating within heating chamber 10b changes not only in the planar direction but also depending on the vertical position, and since the temperature after heating tends to be higher near the center of microwave oven B (near the center between microwave stand b1 and top wall b4) than at a position closer to the microwave stand b1, it was confirmed that it is effective to position object to be heated 10 closer to the center of microwave oven B.

[0025] FIG. 4 illustrates the experimental results of how the center 10a of the object 10 is heated, with the horizontal axis representing the lift distance of the object 10 from the microwave stand b1 and the vertical axis representing the temperature after heating. The solid and dashed lines are the results of two tests performed on the same object 10. Although there is some error in both results, the temperature of the center 10a drops temporarily in the region where the raised height is between 3 cm and 5 cm, and then rises again at 5 cm or more. This suggests that the optimal support height varies depending on the type of microwave oven B and the type of object 10, as this microwave oven may have such a focused distribution of microwaves X.

[0026] For this reason, it is not possible to define an appropriate height in general, but by setting the height for each object to be heated (frozen food) while taking into account the average characteristics of the microwave oven B that is expected to be used, it is possible to achieve a heating state that matches the attributes of the object to be heated 10.

[0027] Therefore, it is preferable to put this microwave conditioner A for use in a microwave oven on the market enclosed in a container (such as a plastic bag) 100 containing frozen food 10, as shown in Fig. 5. Although there will be some error depending on the microwave oven B used, it is possible to enclose a microwave conditioner A with a lifting height set as optimally as possible for each frozen food 10.

[0028] When the bag 100 containing the frozen food 10 is small, it is preferable to fold the microwave adjuster A for use in a microwave oven and store it therein.

[0029] In such a case, as shown in Fig. 6(a) of a microwave conditioner A' for a microwave oven, it is preferable to assemble the device into a polygonal prism (triangular prism) shape as shown in Fig. 6(b) by using the folding line 1h when folded so that the folding line 1h becomes a corner. In this way, the object to be heated 10 is supported in a triangular prism shape rather than a cylinder, but it is possible to achieve both a compact storage function and an appropriate height raising function. Of course, it is also possible to stretch the folds and use the device in a substantially cylindrical shape.

[0030] Also, to accommodate height differences, for example, as shown in Fig. 7(a), guides g1, g2, etc., such as cut lines or perforations, can be provided at multiple width dimension positions along the width direction, and by cutting with scissors or tearing by hand at those positions, a microwave adjuster A'' for use with a microwave oven can be made whose raised height when assembled can be adjusted from Wa to Wb to Wc. Alternatively, as shown in Fig. 7(b), the height of microwave adjuster A'' for use with a microwave oven can be adjusted by bending inward the positions of guide g1, etc., so that the raised height when assembled can be adjusted from Wa to Wb.

[0031] As described above, the microwave adjustment device A for a microwave oven according to this embodiment is formed by bending the plate-shaped material 1 in a circular shape and engaging the ends 1a, 1b to form a three-dimensional structure AA, and by placing the three-dimensional structure AA on the microwave stand b1 with a direction perpendicular to the circular direction facing up and down, the amount of microwaves reflected inside the oven and reaching the center 10a of the object 10 to be heated is increased.

[0032] In this way, by efficiently heating the center portion 10a of the object to be heated 10, it is possible to prevent cold areas from remaining after the entire object has been moderately heated, and to improve the uniformity of the entire heating. Moreover, if the microwave adjustment tool A is made in this shape, it is difficult to buckle when it is made into a three-dimensional structure AA, even though it has a simple shape, and it can be used as something that is extremely convenient to handle and to set / remove the object to be heated 10.

[0033] In particular, since the plate-like material 1 is strip-shaped and the width dimension W is simply set to a predetermined lifting height, it can easily accommodate the type of object to be heated 10 and the type of microwave oven B (such as an average microwave oven or a specific microwave oven).

[0034] The plate material 1 preferably has a guide g for cutting or folding back along the longitudinal direction, thereby making the width dimension adjustable. This allows the plate material 1 to be optimized for each application even if a common plate material 1 is used.

[0035] When the three-dimensional structure AA is cylindrical, the support surface becomes uniform, so that the support of the object to be heated is stable and the support strength can be increased.

[0036] When the three-dimensional structure AA is in the shape of a polygonal column, it can be folded to facilitate packing into the packaging container 100 for the frozen food 10.

[0037] By enclosing the microwave adjuster B for use in a microwave oven in the packaging container 100, it is possible to provide a microwave adjuster A for use in a microwave oven set to an appropriate raising height for each frozen food 10.

[0038] Although an embodiment of the present invention has been described above, the specific configuration of each part is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0039] For example, the plate-shaped material may be a waterproof or water-repellent material, or a material that generates heat when exposed to microwaves. Some microwave ovens have a built-in microwave generator under the oven stand, but even in this case, the amount of microwave light focused can be distributed in the height direction, so it is effective to make it possible to change and adjust the height of the object to be heated from the oven stand.
