[0017]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0018]
(Example 1)
FIG. 1 is a sectional view showing the configuration of a cooking utensil for a high-frequency heating device according to the present invention.
[0019]
The cooking utensil 9 for a high-frequency heating device includes a tray 12 on a high-frequency heating element 11 having a high-frequency heating film 10 provided on the back surface. The saucer 12 is provided with wavy irregularities, and a gap 13 is provided between the high-frequency heating element 11 and the saucer 12.
[0020]
FIG. 2 is a cross-sectional view of a configuration in which the cooking utensil for a high-frequency heating device of the present invention is installed in a high-frequency heating device.
[0021]
The high-frequency heating device 14 includes a heating chamber 15 that accommodates an object to be heated, a heating unit 16 that performs heater heating provided in the upper part of the heating chamber, and a high-frequency generation unit that generates high frequency and performs high-frequency heating provided on the bottom surface of the heating chamber. 17, and the cooking utensil 9 for high-frequency heating equipment is installed on the rail 18. The high frequency transmitted from the high frequency generation means 17 is supplied to the heating chamber 15 from below by the high frequency dispersion means 19.
[0022]
The ceramic high-frequency heating element 11 provided with the high-frequency heating film 9 made of nitride and boride is used as the high-frequency heating element 11, and the surface of the aluminum-plated steel sheet in which the surface is provided with wavy irregularities and the gap 13 is provided. A saucer 12 having a fluorine coating and a black heat-resistant coating on the back surface was used.
[0023]
Using chicken thighs as the object to be heated, preheating for 10 minutes with the high-frequency heating element and the saucer placed, and then simultaneously heating for 10 minutes with the upper heater 600W and the high-frequency 300W as the heating means 16, both inside and front and back It was heated moderately, and especially the front and back sides were uniformly burnt and the finish was good. The water reduction rate was 13%, and it was completed juicy. Also, without the hassle of flipping the chicken thighs, the inside was heated and the inside and outside were burnt.
[0024]
This is because the provision of the gap 13 increases the electric field strength on the high-frequency absorption film 10 by increasing the distance between the high-frequency absorption film 10 and the metal surface of the tray 11, and heat generation at the high-frequency absorption film 10 occurs. This is thought to be due to the increase. Moreover, since the amount of high-frequency waves that wrap around the front side of the saucer 12 is smaller than when there is no gap, the water reduction rate of chickens does not increase, and it is considered that good burns are on the front and back.
[0025]
Moreover, when the surface of the saucer 12 is not provided with a wave-like unevenness and the gap 13 is not provided, the back side is thin and the high frequency is supplied to the chicken. As a result, the water reduction rate of the chicken is 24. The chicken thighs shrunk and hardened, and the back surface was hard to get burnt.
[0026]
This is because the electric field intensity on the high-frequency absorption film 10 is low because the distance between the radio wave absorption film 10 and the metal surface of the tray 12 is short, the heat generation at the high-frequency absorption film 10 is low, and the high frequency is on the front side of the tray 12. It is thought that because the amount of wrapping around increased, the water reduction rate of chickens also increased, and it became difficult for burnt eyes to stick to the back side.
[0027]
Moreover, the difference in the effect with and without the metal tray 10 and the difference with and without the gap 13 were compared by heating the high-frequency heating device 4 with water. Comparison was made when 100 ml of water at 10 ° C. was heated at 1000 W for 10 seconds.
[0028]
When there was no metal tray, the water temperature rose 5.7 ° C., and 342 W was supplied to the water when converted to output.
[0029]
When there was a metal saucer and there was no gap, the water temperature rose 4.7 ° C., and 282 W was supplied to the water when converted to output.
[0030]
When there was a metal saucer and there was a gap, the water temperature rose 3.0 ° C., and when converted into output, 180 W was supplied to the water.
[0031]
On the other hand, when there was no metal tray, the temperature of the bottom surface of the high-frequency heating element increased by 7 ° C. from 23 ° C. to 30 ° C.
[0032]
When there was a metal tray and there was no gap, the temperature of the bottom surface of the high-frequency heating element was increased by 2 ° C. from 23 ° C. to 25 ° C.
[0033]
When there was a metal saucer and there was a gap, the temperature of the bottom surface of the high-frequency heating element increased by 11 ° C. from 23 ° C. to 34 ° C.
[0034]
From the above, it can be seen that when only a high-frequency heating element is used as a saucer and high-frequency heating is performed, more high-frequency is supplied to the object to be heated than when there is a metal saucer.
[0035]
Also, even when a metal tray is installed on the high-frequency heating element, it can be seen that if there is no gap, the temperature of the high-frequency heating element is not increased, i.e., it is difficult to be heated. It can be seen that many high frequencies are supplied to the object to be heated. In the case of chickens, the lower surface is burnt, but a lot of high frequency is supplied to the chickens.
[0036]
It can also be seen that by providing a gap in the metal tray, the amount of high frequency supplied to the object to be heated is smaller than when there is no gap. This is considered to be the reason that chicken thighs were heated well without shrinking and burnt.
[0037]
In the above description, the heater heating and the high frequency heating are performed simultaneously. However, they may be performed separately or may be repeated simultaneously.
[0038]
In addition, when the case where there is a radio wave transmission port on the side and the case where there is a radio wave transmission port below, there was less heating unevenness when it was below.
[0039]
The longer the rail 18 is installed in the depth direction, the smaller the gap between the tray 12 and the side wall surface, and the high frequency supplied from below is less likely to wrap around the tray 12 so that the bottom surface of the object to be heated is burnt. Became easier to attach.
[0040]
By arranging the outer shape of the saucer so that the gap between the heating chamber side wall surface and the door closing the heating chamber is reduced so that the heating chamber is divided into an upper part and a lower part, The high-frequency wave supplied from the slab is less likely to circulate above the saucer, the amount of microwaves supplied to the high-frequency heating element is increased, and the bottom surface of the object to be heated is more easily burnt.
[0041]
As the heating means 16, hot air may be used in addition to the tube heater and the sheathed heater. In addition to the configuration in which the high-frequency heat generating film 10 is provided on the back surface, the high-frequency heat generating body 11 may be formed of a ceramic that generates heat at a high frequency.
[0042]
Although not shown in FIG. 1, a ceramic plate is provided on the lower surface of the high-frequency dispersion means 19 on the bottom of the heating chamber, and is used as a table on which to-be-heated items such as cooked food during high-frequency heating are placed. In other words, the cooked food is not applied to the high frequency dispersion device 19 or the like.
[0043]
In addition, although the aluminum plating steel plate was used for the metal receiving tray 10, as long as the metal does not transmit high frequency, various plating steel plates such as stainless steel, aluminum and aluminum alloy, galvanized steel plate, aluminum zinc alloy plated steel plate and copper plated steel plate are used. Cold rolled steel sheets, clad materials, etc. can also be used.
[0044]
(Example 2)
In FIG. 3, the structure sectional drawing of the cooking utensil for high frequency heating apparatuses of 2nd Example is shown.
[0045]
In FIG. 3, the cooking utensil 20 for a high-frequency heating device has a configuration in which a gap 24 is provided between a high-frequency heating element 22 provided with a high-frequency heating film 21 and a metal tray 23.
[0046]
When the cooking utensil 20 for the high-frequency heating device of the present invention was installed in the high-frequency heating device 14 shown in Example 1 and the chicken leg was heated, the front and back could be burnt.
[0047]
This is considered to be due to the fact that the electric field strength on the high-frequency absorption film 21 is increased by increasing the distance between the high-frequency absorption film 21 and the metal surface of the tray 23, and the heat generation at the high-frequency absorption film 21 is increased. . Also, compared to when there is no gap, the amount of high-frequency waves that wrap around the front side of the saucer 23 is reduced, so the water reduction rate of chickens does not increase, and it is considered that good burns are on the front and back.
[0048]
(Example 3)
In FIG. 4, the structure sectional drawing of the cooking utensil for high frequency heating apparatuses of 3rd Example is shown.
[0049]
In FIG. 4, the space 28 corresponding to the gap 13 of the first embodiment is filled between the high-frequency heating element 26 provided with the high-frequency heating film 25 and the metal receiving tray 27, although it is filled with a ceramic material as a dielectric. The distance between the metal surface of the tray 27 and the high-frequency heating film 25 is taken. The other configurations of the high-frequency heating device are the same as those in the first embodiment.
[0050]
When the cooking utensil 20 for the high-frequency heating device of the present invention was installed in the high-frequency heating apparatus 14 shown in Example 1 and the chicken leg was heated, the front and back could be burnt.
[0051]
This is considered to be due to the fact that the electric field strength on the high-frequency absorption film 25 increases as the distance between the high-frequency absorption film 25 and the metal surface of the tray 27 increases, and the heat generation at the high-frequency absorption film 25 increases. . Moreover, since the amount of high-frequency waves that wrap around the front side of the tray 27 is smaller than when there is no gap, the water reduction rate of chickens does not increase, and it is considered that good burns are on the front and back.
[0052]
Further, when the structure filled with the dielectric is taken, the high-frequency heating element 26 becomes heavy, and on the other hand, since the heat capacity becomes large, there is an effect that it is difficult to cool in the case of constant heating. In addition, since the heat capacity can be increased, it is difficult to cool once preheated, and it is possible to burn it in the case of continuous use or tunnel-type continuous high frequency heating.
[0053]
(Example 4)
In FIG. 5, the structure sectional drawing of the cooking utensil for high frequency heating apparatuses of a 4th Example is shown.

[0058]
When the present invention was installed in the high frequency heating apparatus shown in Example 1 and cooked, the same scorching performance as in Example 1 was obtained. In addition, since the high-frequency heating element 40 is held at the lower part of the tray 41, the high-frequency heating element 40 and the tray 41 are integrated, so that there is no need to take them out separately, and there is an effect that labor can be saved. It was.
[0059]
(Example 6)
