The operation panel 6 and the display 7 are provided in the front position of the machine room 5 of the oven main body 1.

As shown in FIG. 1, the lower part of the inner box 3 is formed in the shape of a plate having a support end 3a, and the bottom end 8 is installed on the support end 3a, and the inner box 3 is provided. The inside of) is partitioned up and down by the bottom plate 8 by the heating chamber 9 which is two rooms, and the bottom part 10 of the heating chamber 9. The bottom plate 8 is formed of a microwave transmitting member, for example, ceramic, for the purpose of transmitting microwaves when using a stove function, which is a function of an oven. The bottom plate 8 is a so-called flat table, and as shown in FIG. 3, the far-infrared light-generating film 8a is applied to the entire surface of the upper surface at least on the heating chamber 9 side, and has a far-infrared light generating function.

The far-infrared generating film 8a is formed by applying a glaze having a far-infrared radiation action. The glaze is made of, for example, aluminum oxide (AL ₂ O ₃ ) or lithium oxide (Li) based on, for example, silicon oxide (SiO ₂ ). _It is set as the composition which mix | blended 2O). Originally, ceramics materials have excellent far-infrared radiation effects, but by adding inorganic pigments to the glaze, they emit far-infrared rays more efficiently.

Moreover, a far-infrared coating film is apply | coated also to the at least inner whole surface of the left side, right side plate, back plate, and ceiling plate of the heating chamber 9.

In the machine room 5, a magnetron 11, which is a device for generating microwaves, is provided. Moreover, the excitation port 12 is provided in the lower surface of the bottom part 10 of the heating chamber 9. A waveguide 13 is provided between the magnetron and the aftershock hole 12 to guide the excitation hole 12 while reflecting the microwaves generated by the magnetron 11. When the bottom plate 8 is installed on the support means 3a by the excitation opening 12 installed on the bottom portion 10 as described above, the bottom plate 8 covers the aftershock opening 12. The bottom plate 10 is provided with a rotating antenna 14 freely rotatable for reflecting the microwaves reaching the excitation port 12 into the heating chamber 9, and the rotating antenna 14 is arranged around the shaft 15. It is to be rotated by the motor 16 through. The rotary antenna 14 is formed of a material that is difficult to absorb microwaves for reflecting microwaves, and rotates during microwave oscillation to diffuse microwaves radiated from the excitation port 12 into the heating chamber 9. As a result, the heated object 19 is uniformly heated in the heating chamber 9.

In addition, the bottom portion 10 is provided with an electric heater, for example, a rectangular frame-shaped sheathed heater 17 located below the bottom plate 8, and includes a ceiling member of the heating chamber 2, For example, an upper electric heater, for example, a flat heater 18, is provided on the top surface of the ceiling plate.

Subsequently, the operation of the embodiment will be described.

First, in the case of oven cooking, the cooked material 19 (in the first embodiment, bread is placed on the bottom plate 8), and the sheath heater 17 and the flat-panel 18 are energized by operation of the operation panel. It heats and heats and cooks the to-be-processed object 19 in the heating chamber 9. And in the far infrared generation coating film 8a of the bottom plate 8, it is heated by the sheath heater 17, and produces far-infrared rays. In the far-infrared ray generating coating film on the inner surface of the heating chamber 9, far infrared rays are generated by being heated by the planar heater 18 and the sheath heater 17.

In this way, the workpiece 19 placed on the bottom plate 8 is formed by the far-infrared rays and sheath heater 17 and the plane heater 18 generated on the entire inner surface of the bottom plate 8 and the heating chamber 9. Heated, in other words, far-infrared radiation and heater heating.

Subsequently, when the microwave cooking is carried out, the magnetron 11 is energized by operating the operation panel 6 to generate microwaves, and the microwaves are guided into the bottom portion 10 through the waveguide 13 and the excitation port 12. Then, it is reflected by the rotating antenna 14, penetrates the bottom plate 8, is radiated into the heating chamber 9, and heating cooking of the workpiece 19 is performed.

As described above, according to the present embodiment, since the far infrared ray is generated from the bottom plate 8 necessary for forming the heating chamber 9, a cooking utensil which is a conventional accessory generating far infrared rays is unnecessary. In addition, the sieve heater 17 and the flat heater swell in the workpiece 19 due to the far-infrared effect emitted from the far-infrared ray-generating coating film 8a applied to the entire inner surface of the bottom plate 8 and the heating chamber 9. The outside can be baked yellow by the heating of 18). In addition, the bottom plate 8 covers the exciter openings 12 formed in the bottom portion 10, so that the heat in the heating chamber 9 can be prevented from leaking from the exciter openings 12 during oven cooking.

In addition, since the bottom plate 8 is formed of a ceramic which is a microwave transmitting member, there is no problem in microwave transmission at the time of stove cooking.

In this case, the outer peripheral edge portion and the central circular portion on the lower surface of the bottom plate 20 become uncoated portions 20c and 20d to which the microwave heating element 20b is not applied so as to change the coating density.

For convenience of description in the second embodiment, referring to FIG. 1, when the microwave generated by the magnetron 11 is emitted into the bottom plate 10, the microwave heating element 20b applied to the bottom plate 20 receives the microwaves. It generates heat and heats the far-infrared coating 20a. The heated far infrared rays generating film 20a generates far infrared rays. In the vicinity of the non-coating portion 20d at the center of the bottom plate 20, microwaves diffused and reflected by the rotary antenna 14 pass through the heating chamber 9 to be used for cooking. In this way, even when the stove function is used, the cooked object can be cooked by microwaves and far infrared rays.

(Third embodiment)

5 is a third embodiment of the present invention, which is different from the first or second embodiment in that the shelf 21 is formed on the left and right side plates of the heating chamber 9 to support the net 21. It is a configuration to be floated on the bottom plate (20). The rest of the configuration is the same as in the first or second embodiment.

This third embodiment is particularly suitable for reheating cooked food 22 (fish in the embodiment) or for cooking without cooking the inner surface of the cooked food. Alternatively, the same effects as in the second embodiment can be obtained.

In addition, in the third embodiment, when the cooked object 22, for example, fish is cooked by installing the net 21 on the shelf support 9a formed inside the heating chamber 9, the fish 22 is used. Because the liquid leaking out from the net does not accumulate, it can be cooked without wetting the inside of the fish 22. By such a structure, the inside of the fish 22 can be cooked so that it may not be called, and it can be heated and cooked smoothly by far-infrared heating to the inside.
