In addition, a parallel link mechanism or an eccentric cam need not be used as long as the mechanism performs the same operation.

Next, a method of using the present configuration will be described. First, an ordered food material A is taken out of the types displayed in the frozen showcase in response to a customer's order, and the composite heating cooker 1 is taken out.
, And the food A is placed on the fixed heating panel 3 in the heating chamber 2.

Here, the ingredients A will be described. C is a sandwich bread, D is an ingredient such as a hamburger, etc.
It is packaged in a heat-resistant bag B having a heat-resistant performance close to 00 ° C. The food material A is frozen in a state of being packaged in the heat-resistant bag B.
Therefore, the food material A can be produced at the factory as planned.

Next, when the door is closed and the start button is pressed,
The movable heating plate 4 is moved down by the vertical movement mechanism 6 and is gently heated while being sandwiched between the fixed heating plate 3 and the radiating antenna 5 in the heating chamber 2 so that the food A is not crushed.

When heating is performed for about 30 seconds, the power for heating is turned off by the timer, and the movable heating platen 4 rises.
When you hear the sound, open the door and cook the ingredients A
And take it out to the customer. Even if the customer takes it home, the core temperature of the ingredients is as high as 80 ° C., so if the time is about 30 minutes, the customer can eat sufficiently warm and delicious.

For the safety of a person using the combined cooking device 1, the door is locked during heating, and may be accidentally exposed to microwaves or may be burned by touching the movable heating plate during heating. It is considered that there is no.

Ingredient A, which is a frozen sandwich, contains 3
Since it is packaged in a heat-resistant bag B with a heat-resistant performance close to 00 ° C,
Heating can be performed by directly sandwiching between the heating plates 3 and 4.
Heat-resistant bag B even if sandwich bread C is frozen
, The surface of the sandwich bread C is baked to make it crisp and flavorful.

In addition, the ingredient D such as a hamburger in a frozen state is:
The powerful microwave instantly warms up and turns into a delicious hot sandwich in a short time.

FIG. 6 shows a specific embodiment of the combined cooking device according to the fourth aspect of the present invention. In this configuration, the heating plates 30 and 40 that heat the food A in between, and the radiating antenna 5b of the microwave heating device that radiates microwaves, which are electromagnetic waves, to the food A from above the upper heating plate 40 to heat the food A. The same components as those of the above-described embodiment are denoted by the same reference numerals, and the details thereof are omitted. The radiation antenna 5c is also provided below the lower heating panel 30 (further, these heating panels 30, 40).
May be installed on the side).

The heating plates 30 and 40 have a large number of punching holes 31 and 41 formed in the surface thereof, and have heating wires 32 and 42 such as nichrome wires built therein. in this way,
By providing the punching holes 31 and 41, microwaves emitted from the radiation antennas 5b and 5c can be heated.
0 is transmitted to the food material A from above and below, and is designed to be easily heated by microwaves. The diameter of the punching holes 31 and 41 needs to be at least 3 mm or more in order to improve the microwave transmittance. In the configuration of the above embodiment in which microwaves are radiated only from the side, while the frozen portion in order from the side to the inside of the food material A melts and dissipates as steam, the water is eliminated by the above thawing. Only the surface is burnt by the heat treatment by the heating plates 30 and 40,
The interior often remained unthawed.
However, in this configuration in which microwaves are radiated from above and below the food material A, since the microwaves reach the core of the food material A and promote quick thawing, the baking of the surface by the heating plates 30 and 40 is moderate. In addition, since the core of the ingredient A has been completely thawed and is sufficiently warm, it is possible to finish the baked condition just before eating. In order to prevent the punching holes 31 and 41 from being directly radiated to the heating wires 32 and 42 and burned out (to prevent only the heating wires from being used for heating the food material A), avoid them. Has been drilled.

Further, in the present configuration, as shown in FIG.
3 and 43, and a space is provided on the opposite surface side of the upper heating plate 40 to cover with the heat-resistant glass 44. Glass material has good thermal conductivity, but is inferior in heat storage,
The surface side to be brought into contact with the food material A may be configured so as to directly cover the surface of the heating plates 30 and 40, but if the opposite side is covered without opening a gap, heat is radiated from the surface side that is not in contact with the food material A. As a result, the heat efficiency of the upper heating plate 40 is deteriorated. Therefore, a gap is provided on the opposite surface side of the upper heating plate 40 as described above so that heat is stored there and heat radiation is suppressed. On the other hand, since the air warmed by the heat rises as it is, there is no need to store heat, especially on the side of the lower heating plate 30 which is not in contact with the food A, and it is necessary to promote the rise of the air due to the heat radiation. The surface side is configured to be directly covered with the heat-resistant glass 34. When the lower heating plate 30 is used in a floating state at least at the time of heating, as shown in FIG. 8, the air radiated from the non-contact surface side easily rises, and the heating efficiency further increases. .

FIG. 9 shows another configuration of the heating panels 35 and 45 used in the configuration of the fourth aspect. That is, in this configuration, a large number of punching holes 31 and 41 are formed in the surface, and the heating plates 35 and 45 are formed by current heating plates that generate heat by the resistance heat when a current is applied. With this configuration, it is possible to raise the temperature instantaneously because the heating itself generates heat when applied with current, without the need to incorporate the heating wire into the heating plate, which simplifies manufacturing and reduces the thickness. And temperature control becomes easier.

[0033]

As described above, according to the configuration of the composite cooking device of the present invention, the foodstuffs such as frozen sandwiches and the like which are heat-resistant packaged are directly sandwiched and heated, and at the same time, heated by electromagnetic waves, thereby making the food delicious and drastically improved. Cooking time will be reduced. In the configuration in which the electromagnetic wave is radiated from the top and bottom of the food material as in the structure of the fourth aspect, the electromagnetic wave reaches the core of the food material and prompts thawing quickly, so that the surface of the food is burned appropriately by the heating plate. By the time, the cores of the ingredients have been completely thawed and are warm enough, so that they can be finished just right when eaten.
